Lab Report Banana Dna Essay Example for Free

Lab Report Banana Dna Essay DNA is organized into genes and stores genetic information. DNA molecules are long, slender molecules that carry the heritable information of organisms on to future generations. Because of their size, it is impossible to see a single DNA molecule with the naked eye. It would take about 300,000 DNA molecules side by side to make a bundle as thick as a human hair. When subjected to certain conditions, it is possible to collect â€Å"large† amounts of DNA to make it visible. As part of the chromosomes, the information contained in genes can be transmitted faithfully by parents through gametes to their offspring. For the gene’s DNA to subsequently influence an inherited trait, the stored genetic information in the DNA in most cases is first transferred to a closely related nuclei acid, RNA or ribonucleic acid. In eukaryotic organisms, RNA most ofther carries the genetic information out of the nucleus, where chromosomes reside into the cytoplasm of the cell. In the cytoplasm, the information in RNA is translated into proteins, which serve as the end products of most all genes. The process of transferring information from DNA to RNA is called transcription. The subsequent conversion of the genetic information contained in RNA into a protein is called translation. DNA molecule exists in cells as a long coiled structure often described as a double helix. Each strand of the helix consists of a linear polymer made up of genetic building blocks called nucleotides. There are four types of nucleotides which vary depending on the four nitrogenous bases of the molecule. The four nitrogenous are A(adenine), G(guanine), T(thymine) and C(cytosine). These comprise the genetic alphabet which in various combinations, will specify the components of proteins. It was established in 1953 by James Watson and Francis Crick that the two strands of their proposed double helis are exact complements of one another, such that the rings of the ladder always consists of either A=T, or G=C base pairs. This complementarity between adenine and cytosine nitrogenuos base pairs and between guanine and cytosine nitrogenuos base pase pairs, attracted to one another by hydrogen bonds, is critical to genetic function. Complementarity serves as the basis for both the replication of DNA and for the transcription of DNA into RNA.

Role Of The Nurse In Safe Administration Of Oral Medication Nursing Essay

Role Of The Nurse In Safe Administration Of Oral Medication Nursing Essay Administration of medicines to adults who are physically ill or injured is part of the adult nurses responsibility to provide holistic care and promote health (Veitch Christie 2007). Medicines are manufactured in several forms and can be administered by different routes. According to the form of the medications there are different requirements and equipment for their administration and storage (Burton and Donaldson 2007). This essay will focus on the administration of oral medicines, the standards and the legal requirements for their safe administration. The essay will also look at areas where problems are most likely to arise and will describe the measures which nurses can take to ensure patients safety when administering oral medicines. The National Patient Safety Agency (NPSA) defines patient safety as a process which involves identification, analysis and management of risks and incidents, including medication errors so potential or actual harm to patients can be prevented or minimised. Medication errors have a significant impact on patients, their families and health professionals involved. They can compromise patients safety and result in actual harm to patients. A total of 72,482 medication errors of which 14,111 caused harm of various extents to patients and 37 resulted in death were reported to the NPSA (2009) in one year. The same report showed that nearly half of the incidents were concerned with administration of medicines. Another report by the Department of Health (2004) estimated the cost of medication errors in NHS hospitals between  £200-400 million per year. Therefore it is vital that nurses adopt safe, methodical and skilled approach to administration of medicines. LEGAL The management of all medicines in the United Kingdom is governed by several legislations, the Standards for Medicine Management (2008) and the Standards of conduct, performance and ethics issued by the NMC (2008). The Standards outline the nurses responsibilities in relation to the current UK legislations. Burton Donaldson (2007) summarise these legislations in the latest edition of the Foundations for Nursing Practice. The Medicines Act (1968) regulates the requirements by which medicines are manufactured, prescribed and administered. The Medicines Act (1968) also classifies medicines into four categories which are Prescription only medicines (POMs), Pharmacy only medicines (Ps), General sales medicines (GSLs) and Control drugs (CDs).The Misuse of Drugs Act (1971) and the Misuse of Drugs Regulations (1985) provide the legal framework for the management of the controlled drugs and differentiate medicines according to the level of harm they may cause. The Mental Capacity Act (2005) provides the foundations for care delivery including medicine administration to people who lack the ability to make informed decisions. For Scotland these foundations are contained within The Mental Health (Care and Treatment) (Scotland) Act (2003) and The Adults with Incapacity (Scotland) Act (2000). These regulations are in place to assist and guide nurses and are fundamental in protecting patient safety. Anex1 of the Standards for Medicine Management (NMC 2008) specifies the nurses responsibility to comply with these regulations. However the administration of medication is not solely a mechanistic task to be performed and requires more than just following written instructions (NMC 2004). In respect to oral medicines and their administration the nurse should take a person centred approach and assess and assist each patient individually according to patients general condition. Kelly and Wright (2009) draw attention on the high number of medication administration errors in patients with swallowing difficulties, where physiological abnormalities can lead to difficulties in swallowing of liquids or tablets. Griffith (2005) suggests that alternative form of medicines should be considered if patients have difficulties swallowing tablets. The nurses responsibility in this respect is to perform the initial and ongoing assessment of patients condition to establish the suitability of certain type of oral medicine and the ability of the patient to take this medicine (NMC 2008). Physical or mental health conditions could also have an impact on the medication compliance by patients leading to crushing, mixing or disguising medicines in food or drink (Kelly Wright 2009). The Department of Health (2010) and The National Prescribing Centre (2010) outline the parameters and principles for safe mixing of medicines and the nurses role in this relation. Following these principles when nurses consider mixing of medicines they should always act in line with local policies, consult a pharmacist and obtain written instructions and also obtain consent from patients. Crushing and mixing of medicines without a careful assessment and justification could present safety risks for patients and nurses (Paparella 2010) because of their chemical formulations. Examples of these are the enteric coated tablets, slow released formulations and products containing carcinogenic substances. Crushing or splitting of these medicines may lead to undesirable effects for example unintended rapid absorption. Griffith (2005) points out the legal consequences of crushing tablets. If crushing of oral formulation results in harm for the patient the nurse responsible will be liable for negligence. Paparella (2010) suggests simple steps such as careful consideration whether a tablet is safe to crush and consultations with pharmacist could significantly minimise the risk for patients and nurses. It is also essential that nurses have a sufficient level of knowledge of how medicines interact with the human body in order to be able to observe if they achieve the desired therape utic effect and to avoid any adverse reactions (NMC 2008). Covert administration of medicines represents not only safety risks to patients but also has legal and ethical aspects which nurses have to consider before making a decision for such action (Griffith 2007). Although most of the nurses do not prescribe medicines it has been found that the administration of a wrong dose of medicine causes the largest number of deaths and serious harm to patients, followed by the administration of wrong medicine and omitted or delayed medicine (NPSA 2009). Subsequently, administering wrong dose of medicines has been linked to poor mathematical skills (Pentin Smith 2010). The nurses responsibility in connection with administering correct doses of oral medicines is outlined in the Standards for medicine administration (NMC 2008) which states the nurses must be aware of the patients care plan, check prescription and dosage before administering medicines. Administering of a wrong oral medicine is often associated with similar medicine or patient names, packaging, labelling or poor storage systems (NPSA 2009). This is particularly common issue in nursing and care homes where no wrist bands for identification are used (Pountney 2010). CONCLUSION Safe administration of medicines requires a methodical approach that follows local policies (Burton,C Donaldson,J 2007).

Reflection Of Clinical Practice Nursing Essay

Reflection Of Clinical Practice Nursing Essay The purpose of this essay is to demonstrate application of core components of the NMC Code of Professional Conduct (2008) using reflective practice. The NMC Code of Professional Conduct (2008) states that nurses should act in accordance with the code, using an ethical and legal framework to ensure patient wellbeing and respect confidentiality. Nurses must act in a fair, non-discriminatory way which respects customs, values and beliefs of an individual, providing care which demonstrates sensitivity (NMC 2008, p2). Reflective practice is described by Duffy (2008, p.1405) as an active and deliberate process to critically examine practice, where an individual is challenged to undertake the process of self-enquiry. Refection allows us to look at an experience and how it makes us feel and react, asking what is good and bad, and what can be learnt (Sellman Snelling 2010). Gibbs reflective cycle (1988) allows a systematic and structured analysis and reflection of an event. Description. On my second day of placement in Theatres, I was in the recovery room where a 3 year old boy was being recovered following surgery. The next patient admitted was a Polish lady, who I will call Joanna, in order to maintain confidentiality. She was admitted following an elective termination of pregnancy. Pre operatively she had an interpreter present, but she had returned to the ward and was not present in recovery. When she woke up, Joanna turned to her right and saw the 3 year old boy next to her. She became distressed and started to cry. Joanna appeared to understand no English at all, I tried to calm her down and reassure her, but she did not seem to comprehend. The staff nurse thought that she was upset at seeing the boy after her procedure and went to get a mobile screen to separate the patients. Joanna then became more upset. I called the ward and asked the interpreter to come back to recovery, as the patient was getting more distressed and we were not able to reassure her due t o a communication barrier. The 3 year old boy was also becoming upset. When the interpreter arrived Joanna was able to verbalise that it was the presence of the child that caused her upset and anxiety, as it was the last thing she expected to see when she woke up from anaesthesia. Feelings. I felt helpless as I could not fully understand why she was upset, and I was unable to reassure her or calm her down. I also felt sad and concerned for the 3 year old boy who was obviously distressed by the circumstances. I was concerned that Joanna may have felt more isolated by putting the screen there, and maybe felt judged because of her procedure. I felt the staff nurse assumed the presence of the boy was causing Joannas upset, but that we could not be absolutely sure. Evaluation. Joanna was in a vulnerable position during her post- operative period, and we were unable to help her immediately due to communication barriers. We attempted to resolve what we thought might be the problem by placing the screen, but this appeared to worsen levels of distress for Joanna. Alongside this we were unable to assess her pain, nausea levels and fully explain what we were doing. Positively, we called the interpreter to return as soon as possible to attempt to resolve the situation. I also feel that I was able to look inside myself to challenge my Muslim religious beliefs, which are fundamentally against abortion, putting these aside to treat Joanna in a fair non-discriminatory way. I was able to act in a sensitive and compassionate manner, affirming my belief that I am able to adhere to the Code of Professional Conduct (2008) and its core components. Analysis. The Abortion Act (1967) allows termination of pregnancy up to 24 weeks if continuance of the pregnancy would involve risk to the physical and mental health of the mother. Abortion is one area where health professionals may raise a conscientious objection. Nurses may avoid taking part in the procedure, but must continue to care for the patient, before and after the procedure, despite personal opinions and moral concerns (Royal College of Midwives 1997, NMC 2006). Kane (2009) states in accordance with the NMC nurses must give appropriate and comprehensive care to all patients, regardless of their reason for being in hospital. The Code of Conduct states you must act as an advocate for those in your care (2008, p2), nurses also have a legal obligation to care. I feel I gave appropriate care, regardless of Joannas reason for admission, and did not treat her any differently because of this. The Royal College of Nursing (2012) state that nurses must be culturally competent, caring for the needs of people with differences in beliefs, values and cultures, to provide meaningful, beneficial health care. Health care is compromised when the patient does not understand what is being said to them (Anderson et al. 2003). Communication is seen as a fundamental component in cross cultural care and language difficulties can lead to insufficient care and poor quality nursing (Jirwe et al. 2010, Jacobs et al. 2006). I do feel although we attempted to resolve the situation, our ability to care for Joanna was compromised by not being able to communicate verbally. Jirwe et al. (2010) found in their study that nurses who experienced difficulties in talking to their patients led to care being mechanical and impersonal, as they were fearful of making mistakes. Jirwe et al. (2010) suggest that nursing programs need to address this deficit to ensure nurses are skilled to deal with cross cultu ral differences, such as using translators, nonverbal communication etc. This is supported by Jacobs et al. (2006) who state that people with limited English are less likely to receive the care they need and are less satisfied with health care. The only factor that can improve this is the use of someone who speaks their language, i.e. an interpreter. Carnevale et al. (2009) state that linguistic barriers can cause discrimination and compromise nursing care. They apply ethical theory in that the patient should be respected as a unique person, their right to self-determination upheld, respect for privacy and the nurses responsibility for ones competence and judgement. Veiga et al. (2011) found in their research that the presence of a support person in the recovery room post termination was perceived by the women in a positive manner and also reduced anxiety levels. Termination of pregnancy is associated with pain, which can be exacerbated by anxiety and psychological factors (Pud et al. 2005). It is estimated 10-20% of women following terminations suffer from serious negative psychological complications such as anxiety, depression and sleep disturbances (Coleman et al 2005). I am concerned that Joannas level of anxiety, may have caused her increased pain, and may also have affected her recovery in the longer term. I was unable to find any research that suggested that adults and children should not be recovered together. However there is a drive in the UK to provide same sex accommodation where possible in order to promote dignity and privacy (NHS Institute for Innovation Improvement 2010). A privacy and dignity report by the Chief Nursing Officer stated that screens if used should be high enough to feel like they are in a separate room. Conclusion. Based upon the literature reviewed during the analysis, it is evident that an interpreter should have been available to reduce Joannas stress, anxiety and even pain response. We do not always know how a patient will recover in the immediate postoperative period and patients can often be disorientated. This was made worse for Joanna as she did not understand what was happening. We could not effectively give reassurance, or fully assess the situation due to the language barrier. The only way in which this could have been resolved was to have the interpreter present when she came round from her anaesthetic. In reflection, the screen should have been in place before Joanna came round from theatre to protect both her, and the 3 year old boys dignity and privacy. If the screen had been in place, then this incident would not have occurred. It I difficult to say whether placing the screen was the right action after Joanna became upset, as it seemed to cause Joanna more distress. However, we also had to take into consideration the 3 year old boy, who was frightened, scared and also becoming upset. It is my opinion that this was in both patients best interests to place the screen after the fact, although it would have been a better situation if the interpreter had been present. It must however be said, that it is not always possible to have an interpreter due to scarce resources, but as the patients advocate, we should do all we can to protect their best interests. Action Plan. In future, regardless of my location, I will endeavour to be aware of potential problems that may arise due to the patients circumstance or environment. I will be more focused on making sure that all resources are in place, such as anticipating when an interpreter may be necessary, and also ensuring dignity and privacy are maintained. I feel this reflective essay has been invaluable, and I am able to demonstrate ethical practice, acting in a non-discriminatory and fair manner, within a legal framework , despite my own personal beliefs.

Mark Twain/ Huck Finn Essay -- essays research papers

In Mark Twains’ books he relates himself to a characters by giving them some of his personal life and history. In the book The Adventures of Huck Finn, Mark Twain relates the most to the main character of Huck Finn. Mark Twain and the character Huck Finn have similarities in their lives, such as, Twain placing Huck on the river he grew up on, having Huck not be specific with his religious beliefs, and never staying in the same place for long.   Ã‚  Ã‚  Ã‚  Ã‚  The main thing that stood out in the book was that the story always happened around the river. Huck would go away from the river for a while but would always end up coming back to it a short time later. It was the same way with Mark Twain, whose real name is Samuel Langhorne Clemens. â€Å"Mark Twain† is a river man's term for water that was just barely safe for navigation (Kaplan). He was only four years old when his family moved to Hannibal, a small town in Marion County on the west bank of the Mississippi River. There Clemens spent his boyhood, amazed by the romance and shocked by the violence of the river life, with the steamboats, keelboats, and giant lumber rafts, as well as by the people who washed up by the river, the professional gamblers and confidence men. Near the river, the men were fierce and had little cares. It was no place for a young boy.   Ã‚  Ã‚  Ã‚  Ã‚  Further from the banks of the Mississippi was Hannibal. Hannibal was a fine place to raise children. There were many places to go with fun things for young boys to do. Twain let his imagination go when he went to places like Holliday’s Hill and the caves close to the summit, where he may have played pirates just like Huck. A close friend of Clemens was Tom Blankenship, the son of the village drunkard, who was to be immortalized years later as Huck’s friend Tom Sawyer (The Adventures of Tom Sawyer). Tom Sawyer is Huck Finn’s best friend in the book. Tom freely invents lies and loves adventure, just as Tom Blankenship did.   Ã‚  Ã‚  Ã‚  Ã‚  When Clemens was just a young boy he saw death on the river and in his owns home. One of his sisters died when he was four years old, and his brother died three years later when he was seven years old (Encyclopedia Britannica). After the death of Samuel Clemens’ father, it became necessary for him to contribute to supporting his family. He worked so hard that he bu... ...g. So Clemens rode the Mississippi for almost four years, and he remembered these years as the most carefree of his life.   Ã‚  Ã‚  Ã‚  Ã‚  The river is the main focus of the book. They never seem to stay away from it for very long. Even with all the bad stuff going on at the river, it seems to be the only place that Clemens and Huck can find peace. The river even takes his evil father away from him for good. Through spending so much time with Jim, and all the experiences on the river, Huck reveals a strong sense of humanity (â€Å"Huck Finn Notesâ€Å"). He showed this when he did everything he could to save the two murderers who fell off of the ship. Huck will always do everything that he can to help a person if they need it. Huck is a very clever character who always thinks his plans out, unlike Tom who just acts upon an idea.   Ã‚  Ã‚  Ã‚  Ã‚  Clemens seems to use his childhood experiences to write this book. To represent his self as a child he uses Huck and lets him live out all of his childhood adventures. Twain and Finn are similar because they both grew up on the river, have no specific religious beliefs, and they never stay in one place for a long time.

Shakespeares Hamlet - The Ghost Of Hamlet’s Father Essay -- GCSE Engl

The Ghost Of Hamlet’s Father      Ã‚   What would Shakespeare’s tragedy, Hamlet, be like without the character of the Ghost? The drama simple wouldn’t BE! The Ghost, though not a human character in most senses of the word, is crucial for the development of the play. This essay will analyze this interesting character.    Frank Kermode in â€Å"Hamlet† fits the Ghost into the local and national scene:    But meanwhile the ghost – â€Å"this thing† – has appeared. (Horatio as skeptic raises questions as to its status which could have been avoided.) There has been speculation as to its purpose, but one thing seems sure: it has to do with the state of the nation – it   â€Å"bodes some strange eruption to our state† – and with the armaments drive now in progress under the threat from Norway. That it genuinely has to do with the state of the nation – its spiritual rather than its merely political state – we shall learn; and to give us a â€Å"musical’ sense that this is so, there is the unexpected speech about Christmas. (1138)    The Ghost means more than a commentary on the spiritual and political state of the nation. Gunnar Boklund’s   â€Å"Judgment in Hamlet† introduces the Ghost in terms of the dilemma of the protagonist:      It is a commonplace to refer to Hamlet’s â€Å"dilemma† and a critical problem to explain in what this dilemma consists. A natural way to come to terms with the problem is obviously through the character that forces the dilemma upon Hamlet, that is to say, the Ghost. This is a particularly attractive approach, since it promises to bring the findings of modern research into Elizabethan demonology to bear directly upon the question of the nature of the Ghost and its message. It was apparently generally believed, a... .... San Diego: Greenhaven Press, 1999. Rpt. from The Masks of Hamlet. Newark, NJ: University of Delaware Press, 1992.    Shakespeare, William.

Hotel Reservation

I. Statement of Scope and Objectives A. Introduction Technological innovation cause changes in the way people live. They have made lives of people easier, more comfortable and convenient and even hoteliers and services oriented companies find ways how to satisfy their customers, But how these hoteliers manage their transaction with fast and more convenient way. The Columban College Hotel & Resort is founded Dr. Susan P. Alegoria, the Dean of the College of Business Administration, with the recommending approval of the school treasurer Fr. Amado S. Censon and Rev. Fr. Daniel O.Presto the school President to the Board of Trustees – Most Reverent Bishop Florentino G. Lavarias, DD, as Chairman of the Board. Hotel now are having a hard time keeping their files in place. The procedure implemented is slow in billing. Manual handling of information may lead to inaccuracy of information because humans are prone to errors. In their reservation transaction there is a problem in shifting of schedules of the staff because the records is place only in the logbook and sometimes the staff is not aware that there is a reservation in a specific room because of it is difficult for them to find the room immediately.The proposed computerization system can reduced if not totally eliminates the errors that will be encountering. This system provides efficient and precise output because of the transaction for computation of bills. Accessing and updating records in reservation can be done with relative. It would then be easier for this company to go about their work with less effort and high efficiency. For Columban College Hotel & Resort, a manual-based transaction is still applied that serves as their primary system & when it comes to their data management which is record keeping and report generating.Such processes are done using logbooks, worksheets, price lists, calculators and a lot of human intervention. By doing so, the company has been encountering human errors such as i naccurate calculation, when turns out to be an inconvenience for them as it requires greater effort and time. To complement the need for capability to control, it is essential to develop an information system that will serve as the company’s backbone. Background of the Study Columban College Hotel & Resort was built on the premise of putting aLaboratory facility for BSHRM – Bachelor of Science in Hotel and Restaurant Management and BST – Bachelor of Science in Tourism students. After two years of deliberate construction, a five storey, 15 rooms building complete with three star class facilities finally open its doors on April 15, 2004. A team of experts manage and operate the Hotel Laboratory for the students to experience a first class hospitality education, making them equipped and at par with their counterparts.All Laboratory classes/subjects are done in the hotel; Front Office, Housekeeping, Kitchen Operations, Bar Tending/Cocktail Mixing, Baking with Cake D ecoration, International Cuisine, Events and Catering Management, and Culinary Arts. These specialized subjects are taught by experts from the industry and with NC II certification by TESDA. The Columban College Hotel & Resort, is the first educational hotel in Zambales and Bataan Provinces, it is located at Barrio Barretto, Olongapo City.

The swimming pool – a mini –Olympic size pool with kiddy pool with lush tropical gardens and a roof deck overlooking the Barretto campus and Subic Bay will definitely make your stay wort hwhile. As educational hotel and resort, our tradition of impeccable service will make your stay memorable.The Columban College Hotel & Resort continues to set itself apart with its excellence in Hospitality Service and education as evidence by the result of regional culinary skills competition. The existing system in the organization contains many manual operations, including a manual registration and reservation performed by the guest which creates a problem on the receptionists recording the data that has been gathered, manual transactions of payment also created problem in paying the bills in the hotel. The Columban College Hotel & Resort is having a hard time keeping their files in place. The procedure implemented is slow in billing.Manual handling of information may lead to inaccuracy of information because humans are prone to errors. In their reservation transaction there is a problem in shifting of schedules of the staff because the records is place only in logbook and somet imes the staff is not aware that there is a reservation in a specific room because of it is difficult for them to find the room immediately. Another problem also is the marketing of the hotel because of its location and finding the prospect guests. The proposed computerization system can reduced if not totally eliminates the errors that will be encountering.This system provides efficient and precise output because of the transaction for computation of bills. Accessing and updating records in reservation can be done with relative. Reports are being generated depending on the list required by the management. It would then be easier for the company to go about their work with less effort and with high efficiency. B. Statement of the Problem MAJOR PROBLEM: Based on observation and interview done by the proponents, this study identified that the major problems experienced by the management lies on the manual process of all their operation.SPECIFIC PROBLEMS: 1. Slow Process – It ta kes time to prepare a billing report and billing statement of the clients and unable to determine quickly the availability of the rooms in order to assign new clients to their respective rooms because they are still using manual process. 2. Data Security – Their records will get lost or damaged because their data is not secured and sometimes the receptionists overlooks the records of the reservations and assigns different clients on the same room and same date which makes the manual system unreliable. 3.Intensive labor – They have difficulties on searching clients’ records and scanning the log books for the availability of the rooms it also needs effort in order to compute the billing statement. C. Objectives of the Study GENERAL OBJECTIVE: The general objective is to design and develop a Hotel Management System for Columban College Hotel & Resort, Barrio Barretto, Olongapo City. SPECIFIC OBJECTIVES: 1. To be able to develop a system that will speed up the proce ss of operation. The receptionists will have an ease using this system because our proposed system is capable on computing the payments that clients have made. . To be able to secure a program by creating a different user level of security The proposed system will have a capability to create a back-up of the recent database and the records are protected because the only person who can access their records is the receptionists. 3. To be able to develop a system that will ease the job of different user. With one glance the room’s status will be shown whether it is available, occupied and reserved. The receptionists would no longer look throughout all the rooms’ information on the log book one by one. D. Scope and Limitations ScopeThis study will cover the management of the rooms, the system will show the information of the room if it is occupied or available. The system will provide the computerization of the costumers’ total. The system will record the clientsâ⠂¬â„¢ information and the transaction they settled. Limitations The system limits the direct usage of the system by the clients, only the receptionists can operate the system. Editing guest information & transactions can only be made by the receptionists. E. Locale of the Study Figure 1. 0 The Columban College Hotel & Resort is located at Rizal Ext. Barrio Barretto, Olongapo City, near the Columban College, Barretto Campus. F. Significance of the Study This study aims to provide a Hotel Management System for Columban College Hotel & Resort. With regards to the billing of the guest, the system will be responsible in computing their payment and checking the availability of all rooms. Receptionists: They will consume less time and effort interacting with their clients. Having this system, they can easily access or check the status of the rooms depending on its types. And they can easily give the bill of the clients because it was already computed by the system.Clients: Their clients wi ll not have to wait for a long period of time for the room that will be assigned to them and their bill. Company: The hotel will have a better transaction process and ease in their guest management. II. Review of Related Literature and Studies A. Related Literature This chapter is a discussion of the background, aims and objectives of the present study. This chapter deals with the review of related literature. The purpose of the study of research works done in the same field is to understand what type of study has been done and what exactly has been explored before the present research work started.The system provide the reception an easy way for searching on rooms, listing off rooms, inserting the client information, making reservation for rooms and doing payment process. This will be created by four students of Columban College. They are Jon Roel Lasala(BSCS), Kristian Castillo(BSCS), Steven Ocampo(BSIT) and Rosendo Luy(BSIT). B. RELATED STUDIES Foreign Webraydian (2007) asserted that to run a hotel successfully it is important that the hotel management should be good before making any change in the trends one should take a look to every aspects as any changes in the trend also have a wide impact on the diverse industries.Rutherford (2009) asserted that the hotel business should be done in terms of the guest interest as well because of the growing concern over environment friendly service. O’Fallon (2010) asserted that the hotel business is one of the most competitive businesses in the world or the better words is â€Å"most cut throat†. Michael said that hotel reservations software allows hotels and resorts to manage reservation software allows hotels and resorts to manage reservations, set rates, offer discounts and monitor room allocations. Most otel reservation systems include hotel management software, hotel reservation and billing software, hotel reception software and hotel accounting software modules. Global Marketing asserted that comm unicating with all of these channels in order to keep them current on your inventory and rates, requires in some cases, daily manual intervention with multiple faxes and phone calls. More importantly, verifying the accuracy of each channel’s current allotment and rate by property is critical but rarely automated. Most times hotel operators do not know where or how their rooms are being sold or at what rate until the booking confirmation arrives.Waller said that is hotel hotel reservation software is really a necessary need. Pencil and paper booking sheets for example tend to get the job done, yes? That may be so, but also considers that with hotel reservation software, such booking sheets can be printed out, and many software packages can be configured to most any language. Martindale, asserted that another great feature about using hotel reservation is you can select from any hotel in the area that you want to stay at, even of your budget wouldn’t normally allow you t o afford it.With the online system you can browse the different hotels available in the area, and see if they have only a discounted price or if they will allow you to create your own price. This many sound strange, but especially during off peak times many hotel want people to spend something to stay in their room to help increase their annual revenue. Charya, asserted that Hotel Management system helps the hotel administrators to accommodate special request, booking checkouts, etc. They keep sending reminders highlight the important dates for the benefits of the customers.It also gives the hotel administration leverage in terms of making immediate adjustments as and when something unexpected turn ups. Schneider said that room management is simple and cost effective because a guest room management system can ensure maximum user-friendly and cost effectiveness. Assuresoftware. com testified that the management software can help your people get more out of every minute, every hour, a nd every workday. It is designed to boost productivity by simplifying scheduling rooms and resources. LocalValenzuela (2003) asserted that computer-based hotel reservation and billing system can reduce errors that will be encountered. This system provides efficient and precise output because of the transaction for computation of bills. Reports are being generated depending on the list required by the management since computerization of all companies are being encourage; there is need for hotels to adapt computerized operation too. Razal (2004) testified that the reservation and information are essential to attract clients and customers, so when they see that the establishment that can be added to their success.Wong (2004) concluded that reservation system will lessen the work of the employees and would really help them a lot in managing the hotel and it would be much easy to organize all transactions of the hotel. Capistrano (2005) asserted that reservation system enhance the existi ng business operation and give further improvement for the business process. Fuerte (2005) concluded that an application of IT technology in any business firms hold the key to competitiveness towards development and success in the business.Ramirez (2005) asserted that reservation system will benefit not only the company but customers as well, because it will increase the efficiency of the employees working operation. Daduya (2006) claimed that organized and fast retrieval of information computerization of their reservation and registration process is need, for them to have fast and accessible transaction. Mirador (2007) asserted that reservation system is deemed significant because it will be different from the traditional process of reservation.This will reinstate the manual process of reservation which probably creates difficulty for the people the who are responsible in reservation. C. Analysis on Related Literature and Studies As summary, Hotel Reservation System is an advance p rocess of managing hotel reservation; check in, check out of costumers. It is a user friendly and helps the hotel receptionist to accommodate special request, booking, checkouts. They keep sending reminders and highlight the important dates for the benefits of the costumers.Therefore, hotel that uses Computer based system needs to conduct day training for the users/receptionist to be literate in hotel management system and to avoid difficulties in making reservation of costumers. It lessens the time consume doing the hotel reservation. It is a replacement for manual reservation. A system more convenient and user friendly and compiling of files is more accurate and more sufficient than compiling it manually. It is more easy-driven to ensure faster and reliable data by processing of information in database. III. Methodologies A. Methods of Research StudyIn this chapter, the proponents described the method of research used and data gathering procedure, tools and data processing techniq ues. The Proponents used the different gathering materials like internet, books and previous study similar to the proposed study. After collecting and analyzing the data that we gather we found out some of the problems and establish our main objectives that served to be our guidelines for pursuing the system. Those gathered information from questionnaire, surveys and interviews can solved to the problem of the Columban College Hotel & Resort for their manual process. B.Data Gathering Techniques The proponents used the Descriptive Method; it is designed to investigate and to gather information about the present situation. This was the chosen method of the proponents because the method can help the proponents obtain the information they need. There are different ways to gather the information needed for the proponents to understand more about the current system of Columban College and how can the people adjust in the new system that is going to be implemented. The facts and informatio n that was gathered by the proponents was obtained by the use of Observation, Interview and Survey.Observation – this first stage to be done because before doing the interview and survey the proponents needs to observe what kind of environment the locale of the study have, what kind of people is involved and the educational attainment of each people. This technique is very helpful in gathering the needed data because conducting the observation opened some issues and problems that the study will encounter. Interview – by conducting the interview, all the questions and issues of the proponents was brought up and was answered.Interviews were done with the different people who are involves and in-charge of the Columban College Hotel & Resort. Survey – this was used by proponents to determine the percentages of the students who agree and disagree on the proposed system. Using this technique gives the proponents the opportunity to understand the situation of the stude nts in the existing system. The techniques/ways discussed above will not be obtained without the instruments used in data gathering. These instruments were performed carefully and accurately to have a very reliable result in the study.The instruments used to gather the information needed are the Library and the Internet. Library – the proponents used the Library to gather some important information that can help improve the study. It also played a very big part in the study itself; the Library contains a lot of reliable information regarding the study that helped the proponents. Internet – the internet played a vital role in gathering the information needed. The internet nowadays contains information that are not that reliable and accurate, the proponents carefully compared the results and comments of the other readers in the internet to have a result that is reliable.The proponents used survey form as one of the most important method in data gathering. A set of survey questions was given to at least 30 respondents including employee and guests of Columban College Hotel & Resort, who gives the proponents a specific knowledge and help us in identifying the common problems they are facing in a relation to the study. The proponents used Percentile Method to determine the quantities and percentage of the responses in the survey. 1.

Feasibility Study 3. Technical Feasibility Columban College Hotel & Resort is in need of a computer-based system to be able to operate faster and more efficiently. The system project primarily intends to avoid inconsistencies during operation. Also, implying the use of computerized processes avoids inaccurate report of billing amounts and miscalcula tion of transactions.

However, the only thing that the shop need is hosting the proposed system and it is less expensive. The proposed system just need to acquire an internet connection and have knowledge on computer and it will be possible for them to get their needs and information by just browsing.The economic feasibility will illustrate the expenses needed to be able to implement the proposed system successfully below. Since the Columban College Hotel & Resort has already has a one (1) complete set of personal computer, there is no need to buy a new one.

Figure 7. 0 Gantt Chart 3. 5 Feasibility Analysis Executive Summary After the proponents gather all the essential information needed, the proponents is convinced that the proposed system will be feasible in implementing.The proposed system requires both hardware and software components to keep the system running. For the receptionists, the Visual Basic 6. 0 i s needed to run the system. It is important to create a back-up of database to keep the information and transactions safely. Since the needed software and hardware were available in the hotel, the proponents will only now focus in implementing the system to know whether the proposed system will truly help the Columban College Hotel & Resort. 4.

System Design 1. Proposed System This research describes an adaption of a hotel reservation system in Columba n College Hotel & Resort.Computer technology has made our lives much easier and convenient. Years ago, people had to manually input important information of their guest, now you just use the computer to find this information. In just one click, instantly find the guest name, rooms & rates, address, email address, phone numbers and so on. By investigating their existing reservation, the guest input the information manually in reservation form. It is hassle for the guest to do a reservation as well as to the receptionist. It is time a waste of time, effort and the things that is needed for the reservation.Proponents will implement the proposed system in Columban College Hotel and Resort. All you need is computer and a user, by just opening the application. It is a very reliable, efficient and convenient. It is much easier to for the receptionist to look at the database and see if the guests are already paid or if the room is already occupied or unoccupied and so on and so forth. 2.

This is where the additional necessity will be ordered by the guest and the receptionist will process the transaction 5. 2 System Outputs . 3 Process Specifications 5. 4 Integrity Controls All bits of information or data that are gathered in the guest will be stored in the system and its database. Only the receptionist can modify the system in the server through the approval of who might be the one should be approving it. That person who will be approving it will depend on the agreement of the company or policy. 5. 5 Security Controls The proposed system has the capability to back-up th e database of all it saved information. The system will have passwords where only receptionist can access it.Any antivirus programs with high integrity will be used to protect the system. 6. Automation Boundary The proposed system will be about reservation of room accommodation and other services. The system will not be providing automated billing. 7. Initial Gap Analysis The existing system is all about manual operation by filling up form of reservation, unlike the proposed system all you need to do is encode the information. Other advantage of the proposed system its more efficient if compiling reservation form. It is also more accurate in reviewing data information about the previous accommodations.Chapter VI A. Implementation Activities In order to successfully implement the proposed system for Columban College Hotel & Resort, the proponents need to orient the Receptionist, Manager and Owner on how the process of the proposed system works and on how the system should be handled, after orientation and installation the system will be tested and will be evaluated for further revisions or enhancement that are still needed to include on the proposed system. B. Testing 1. Unit Testing The system administrator and other users will be involved in testing the program.The users are allowed to explore the system then let them take notes if there are any flaws in it or if there are anything that needs to improve. Then the proponents will debug the system then re-run the testing for further adjustment and debugging until the system will be fully operational. ALPHA TESTING Alpha testing is a form of preliminary software field test carried out by a team of users in order to find bugs that were not found previously through other tests. The main purpose of alpha testing is to refine the software product by finding and fixing the bugs that were not discovered through previous tests.This indicate the stages of the process how the system response to its given task. The testin g is conducted in order to know how the systems deliver the required response regarding with its performance. Based from the test that has been establish in using alpha testing, the proponents comes up from the first part of testing the system, there were things that must be change. One of the changes that need to be change is the abolishing of the manual procedure of the hotel, 2. Integration Testing 3. Usability TestingAfter all operation testing are done, the Hotel Management System receptionist will seek for questions regarding the improvements of the system. After gathering some information, adjustment or improvements will be done in the system depending on how big are the problems need to be change in the system. 4. User Acceptance Test As all the adjustment or improvements are done, the system will be tested again by the Users and will be re-evaluated if the system already fulfilled the User’s satisfaction. C. Change Request and Error Reports D. Deployment 1. Deploymen t Approaches 2. User’s TrainingIn order for the system to fully-implement in the oraganization, the users must undergo training in order to gain enough knowledge in computer. The training will be about familiarizing in the operating system which is the Windows7 so that the user wil use will know where to go in accessing the system, then the Microsoft Visual Basic. net in order for them to easily understand the environment of the syetm because the system is made through the said software. Then, also most importantly is the users must be trained on how to use the system. The training will be conducted in their free time.In terms of the untoward incident that will happen in the system during the operation, the users are obligued to go out series of trainings for the debugging of the system as well as the system’s maintenace. 3. System Maintenance 1. Problem Report During the previous process, the problems aroused in the system are the following: 2. Manual Changing and Upd ating of records The Hotel’s office consists of many files of the clients and inventories. Since, the office piled up with many files there are many records that needed to be recorded in a new form and add to the database.And also the files are not be placed consequently because the files are only been placed to the filling cabinet in the office. 3. Employees are not Computer Confident The Front Desk Employees does not have sufficient knowledge about computer.

A Comparative Study of Date Leaves as Mulch for Tomato Plants Essay

Science Investigatory projects Dried Papaya Leaves as Organic Mulch for Tomato Plants Mulching in agricultural provides a safe yet equally profitable method of enriching and fertilizing the soil planted with crops. Most often-used mulches are of organic composition, such as dry leaves and barks. Unlike synthetic fertilizers and herbicides, these organic mulches pose no or little damage to the soil and crops. Usually defined as the use of organic and biodegradable materials to give plants the nutrients they need, organic farming proved to be the safest and most effective method of increasing and sustaining yield. Various methods fall under organic farming, such as composting, green manuring, legume inoculating, and utilizing animal manure as fertilizers. Mulching is a simple process that increases soil fertility and regulating several factors affecting overall plant growth. In this method, a layer of material-the mulch-is placed on soil surface around the plant. The mulch is used to retard the growth of weeds, protect roots and stems from sudden or extreme temperature changes, reduce soil erosion by wind and water, retard runoff of rainfall, prevent soil puddling by breaking the impact of raindrops, and keep flowers and fruits from being spattered with mud during rainstorms Used Cooking Oil as an Additive Component of Candle The study aims to produce a low-priced, high-quality candle by using used cooking oil as a major component. The following candle compositions were used: 100 percent paraffin wax; 90 percent paraffin and 10 percent oil; 80 percent paraffin and 20 percent oil; 70 percent paraffin and 30 percent oil; 60 percent paraffin and 40 percent oil; 50 percent paraffin and 50 percent oil. The firmness, texture, and light intensity of the candles were tested and compared. Today, candles are made not only for lighting purposes but for many other uses such as home dà ©cor, novelty collections, as fixtures for big occasions (weddings, baptismals, etc.), and as scented varieties for aromatherapy. Candles are made from different types of waxes and oils. Cooking oil is a major kitchen item in Filipino households. It is also used substantially in fast-food outlets, where it is used in different stages of food preparations. Ordinarily, used cooking oil is discarded. This waste oil pollutes and clogs canals and sewerage systems.
