Digestion of Starch by Salivary Amylase Essay Example

Digestion of Starch by Salivary Amylase Essay The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase, the key enzyme for starch digestion, salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose, amylopectin, and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis, pancreatic resection, pancreatic neoplasm, cystic fibrosis, and other causes of pancreatic insufficiency. Quantitation of salivary amylase in these diseases has yet to be performed. It is also unclear whether the presence of starch in a meal protects salivary amylase from inactivation by the acidic gastric environment. In the first six months of life, pancreatic amylase is very low or absent. Despite this physiologic pancreatic amylase deficiency, young infants seem to tolerate moderate amounts of starches in the diet (1). Fi,rthermore, during acute diarrhea in infancy, soluble polymers of glucose derived from corn are well tolerated. The use of polymers of glucose have the advantage of providing the infant with potential mucosal injury with a carbohydrate source that can e readily absorbed and has a high caloric density with low osmolality (2). It seems, therefore, that salivary amylase and glucoamylase of the small intestinal brush border can compensate for physiologic amylase deficiency in infancy, even during diarrheal episodes. In this issue of Digestive Diseases and Sciences, Fried, Abramson, and Meyer (3) utilized a selective salivary isoamylase inhibitor (4, 5) to quantitate the amount of salivary amylase in postprandial jejunal fluid. This is a comparatively simple method using a wheat isolate that inhibits 88% of salivary amylase nd 27% of pancreatic amylase. Standard curves of amylase inhibitor activity were constructed by mixing known concentrations of pure salivary and Address for reprint requests: Dr. E.

Digestive Diseases and Sciences, Vol. 32, No. 10 (October 1987) pancreatic standard in four to six different ratios. The fraction of amylase uninhibited in the presence of the inhibitor is calculated and plotted against a known pancreatic-salivary amylase ratio. In their hands, 11% of total amylase output was found in ormal subjects. In contrast, 27% was obtained in an achlorhydric subject after a hamburger meal.

When gastric pH is below 3. 0, however, salivary amylase is not detected in the stomach (3, 7). Malagelada et al demonstrated that after a steak sandwich the gastric pH is gt;3. 0 for 60 min (8). Since the stomach will have emptied a substantial portion of its contents by that time, a significant amount of amylase could pass through the stomach without inactivation (8-10). It will be interesting to etermine whether starch alone will protect salivary amylase for inactivation in the stomach without the buffering capacity of other components of a meal; glucose polymers have been known to show some protective effect (11). Although the amylases found in saliva and pancreatic secretion in humans are similar immunologically, they have distinct characteristics in their structure, function, and genetics (12). Salivary amylase is controlled by the Amy 1 locus of the chromosome, while pancreatic amylase is controlled by the Amy 2 lo cus, which is distinctly different from the Amy 1 locus. Salivary amylase nd pancreatic amylases differ from one another by several properties and can be separated by ionexchange chromatography (13) or polyacrylamide gel electrophoresis (14) and isoelectric focusing (15, 16). The salivary and pancreatic amylases are similar in molecular weight (approx 55,000 vs 62,000) (17, 18) and amino acid composition (18). The two isoenzymes are further distinguishable in their sensitivity to selective inhibitors, particularly an isolate from wheat which inhibits salivary amylase to a higher degree than pancreatic amylase (4). Last but not least, salivary and pancreatic amylase diff

buy custom Constructivism Evaluation essay Introduction Knowledge is acquired through interaction of learners with fellow students, teachers and learning materials. To help the learners, instructors should have an understanding of their students by examining them and the resources available to tackle the problem. They should also understand the problem to be solved and examine the kind of knowledge needed by learners to do it. This means that they should have an understanding of the learning process of their students and should be in a position to facilitate it. Learning is defined as modification of behaviour through practice, training and/or experience. According to researchers and scientist however, the definition of learning depends on the type of learning process used. These theories are behaviorism, social cognitive and constructivism (L. Nagowah S. Nagowah, 2009). This paper will focus on the theory of constructivism, its applicability in learning, strengths, weaknesses and an exhaustive comparison with other learning processes. Constructivism This is a learning theory whose basic idea is that learners should create their own understanding of an issue through interaction with others and in relation to knowledge that is already in existence. According to researchers, constructivism is not so much a theory of learning as a model of acquiring knowledge which can be used to create a learning theory (Richardson, 2003). To fully understand the constructivist theory, the following aspects are discussed. a) Social Constructivism This theory suggests that knowledge is constructed by people and its form is determined by the political environment, ideological perceptions, values, exertion of power and an attempt to preserve status, beliefs and economic interests of the people (Richardson, 2003). According to Richardson, an individuals learning process and understanding of their world is influenced by social factors. This means that the learning process involves accommodating shared social beliefs and ideologies to acquire formal knowledge. Social constructivism implies that theories and ideas developed by a learner or individual are viable and applicable in the larger social contexts. Social constructivists believe that knowledge is a function of shared reality which develops out of social limitations affecting the learning process of an individual (Karagiorgi Symeu, 2005). This implies that no learning can occur without interference from social environments surrounding the learner. This means that a learner creates meaning of a situation or a problem based on social interactions and experiences. b) Psychological Constructivism This theory suggests that construction of knowledge is based on experiences of an individual and depends on a learners prior knowledge (Richardson, 2003). According to Richardson, learners do not depend so much on the experiences and ideologies of a social group but on their personal experiences. The theory goes further to suggest that knowledge developed by an individual from his perspective can be adopted by groups formal knowledge. Psychological constructivists believe that realities and experiences are very unique to each individual (Karagiorgi Symeu, 2005). This means that the process of creating knowledge and the knowledge created by learners should be based on teir own experiences without the consideration of experiences from other individuals. To the constructivist, reality is not a function of socio-cultural practices within which a learner resides and social beliefs should therefore not influence the learners perspective in solving problems. This suggests that a learner should be motivated by his beliefs, ideologies and experiences to develop skills to cope with a problem. Behaviorism versus Constructivism Behaviorism as a learning process ignores the psychological ability of an individual and focuses on the observable actions of an individual (L. Nagowah S. Nagowah). Adherents to this theory suggest that learning can be measured by simply observing change in behavior of an individual. To them learning process is passive where knowledge is transferred and acquired by repetition of a new behavioral pattern. Behaviorists believe that the right behaviour pattern for learning can be reinforced by reward or punishment. They believe that learning should be a process of transferring knowledge from the teacher to the students who should be able to reproduce the knowledge when need be. The major difference between behaviorism and constructivism is that, constructivism allows student s to come up with their own understanding of a problem and device ways to resolve it. Constructivism encourages creativity while behaviorism encourages repletion of behavior and knowledge acquired. Cognitive Theory versus Constructivism Cognitive theory puts emphasis on the psychological activity of an individual in the learning process. The proponents of the theory argue that every task requires a unique and different cognitive process to resolve or understand. They insist that it is important to understand and appreciate the metal processes that enable an individual to acquire and retain knowledge so that the processes can be enhanced. To the cognitive psychologists, learning is an active activity for the learners that require creativity (L. Nagowah S. Nagowah). The cognitive theory relates to the role of information processing in learning. This is because the processing aspects such as memory organization and neurological connections form the basis of the cognitive theory. An individual requires cognitive knowledge in order to synthesis information acquired to form meaningful understanding. This theory suggests that learning is acquired at different levels by different individuals depending on their cognitive development. This theory is similar to the behaviorists because it suggests that learning is a process where knowledge is given and absolute. This means that knowledge is passed on from the teacher to the learners. The theory suggests that behavior can be used to deduce the cognitive ability of an individual to process information and apply it in learning (L. Nagowah S. Nagowah). This theory is different form constructivism because it only seeks to understand the processes of thinking that allows learning to take place. Unlike constru ctivism, it does not encourage innovation and it believes in the traditional way of learning where the teacher provides information and knowledge to the students. Constructivism as a learning model has generated a range of mixed feelings and criticism towards learning processes. The proponents support the ideologies and ht e expected outcomes of the model when used in education while those against it base their arguments on the weaknesses of the theory application as ddiscussed below. Strengths of the Constructivism a) Active learning Constructivism places a learner at the centre of the learning process. It fosters motivation of the learner because the students experience the pleasure that comes from solving a problem (Karagiorgi Symeu, 2005). The model also fosters creativity because it suggests that instructors should design problems that can be solved in different ways and leave the students to struggle through the solving process on their own. b) Authentic learning The model fosters authentic learning by offering an opportunity to model problems to fit real life occurrences. This stimulates the learner to own the problems and solve them in their own understanding as if in real life situations (Karagiorgi Symeu, 2005). Authentic learning motivates the learners to implement knowledge in a genuine way thus developing relevance and meaning to their learning process and knowledge. Weaknesses of the Model According to a research done in India, the model of constructivism generates major problems in the education system. The research shows that the model makes it hard to examine the knowledge acquired by learners because its learning process is based on practice and personal experiences. In the particular case of India, the model presented a problem in devising a methodology for written examination (Raina, 2011). The information formed by learners through constructivism learning is not acceptable at face value. It is must be measured against the acceptable already existing knowledge for its applicability in meaning. This is controversial to the aims of the model and the basis under which it is established. Those against the model argue that it is not logical to take the learners through the process of innovation and creativity only to measure them against already existing knowledge. To them, knowledge is information that has already been tested and approved as applicable and requires passing and assimilation. The protagonists of the model argue that acquisition of knowledge should be explicit until learners have acquired basic concepts and skills to engage in creative and active inquiry (Gibbons, 2003). Constructivism presents a problem when applied to absolute learning courses such as learning the English language as opposed to learning science. According to research, use of constructivism to teach language or absolute subjects is not applicable. The instructor cannot be able to allow the learners to formulate their own words so that they can understand the language they are learning. Conclusion Constructivism is applied in learning with the aim of stimulating learners to be creative in solving problems. However, the model presents controversy in evaluation method of the learning process. According to research, use of contemporary evaluation methods is pointless where the model has been used for learning. When applied in a learning context, the expected outcome of the process should be creativity and enhanced skills. However, the outcome is not always the same because the model largely depends on the social culture of an individual and the basic knowledge they can relate to their experiences. This leaves room for more research to be conducted on the models applicability to multicultural learning setup. Buy custom Constructivism Evaluation essay

Health care reform Essay Example | Topics and Well Written Essays - 250 words - 2

Health care reform - Essay Example Therefore, physicians must be able to decide who to see first and the duration they will spend with each patient. Concisely, rationing must embrace efficiency where decisions are made so as to produce the good outcomes. In addition, all individuals must be treated equally but the worst off must be favored. Patients who are in critical conditions should be considered for treatment first, and those who are less ill should come later after the critical ones have been attended to (Hoffman, 2008). Doctors need to assist individuals without discrimination. The action of rationing in health care conforms to my professional and person ethics this is because it does not conflict with any ethical codes (White, 2010). Its main aim is to promote and protect the health of the public through reasonable decisions that will ensure every individual is treated depending on his or her condition. For instance, a doctor can decide to handle a particular case over another one since it is urgent and may lead to death if not handled quickly. This is not against any ethical code, but it is part of maintaining a healthy nation and reducing the mortality rates (Fuchs & Emanuel,

Marketing decisions and planning Essay Example | Topics and Well Written Essays - 1750 words

Marketing decisions and planning - Essay Example For Hemopure, competitive market is represented by the donor blood market and substitute products. The main competitors of Biopure are Baxter and Northfield. Both companies are market leaders relying on the high quality of products and selling history. Competition refers to the creation of differential advantage particularly by the effective management of innovation to meet changing marketing opportunities (Cooper et al 133). Programmed innovation, like Hemopure, is the method of achieving continuous market adjustment; competition is its stimulus. The main difference between Baxter’s and Northfield’s products and Hemopure is that the latter is based on cattle blood used as the main source of hemoglobin. External factors that place a limit on competition and innovation include various types of governmental regulation, accepted industry practices and agreements, and the social. The main strengths of Hemopure are innovative methods of production and hemoglobin extraction. The main weakness is that the product is not ready for immediate launch and will need two additional years of research and development. Also, Northfield laboratories received FDI approval in 1999 (Biopure Corporation 8-9). Veterinary market proposes enormous opportunities for Biopure because it will be the only company producing such products. The main strength is that for the next 3-5 years, Biopure will be the only market leader in this sector. The main weakness is that any other company can enter this market and reduce the price level. Thus, even such lead

The industrial society of Canada is high tech in nature and is quite affluent in its resources. The standard of living of the people is quite high. There has been a significant growth in various industrial sectors of Canada like mining, manufacturing, services sector, etc. after the end of World War II in the year 1945. It has resulted in the transformation of the Canadian economy which was rural in nature into an urban and industrial economy. United States serves as the main trading partner of Canada. There have been various trade agreements between these two countries recently like the North American Free Trade Agreement (NAFTA) and Canada-US Free Trade Agreement (FTA). This has helped in the development of economic integration and trade between the two countries to a considerable amount. Three-fourths of the exports generated from Canada are accounted through a sub stantial amount of surplus in trade with US. Canada is amongst one of the largest supplier of oil, gas, electrical power and other energy sources for United States. Canada managed to have a significant growth in its economy during the period of 1993 to 2007 because of its varied natural resources, modernized plants and labor forces which are highly skilled in nature. At the end of the year 2008, Global Financial Crisis (GFC) had an adverse effect on the Canadian economy and it went into economic recession. In 2009, the country experienced fiscal deficit for the first time in 12 years time. However the major banks in Canada have managed to recover for the ill effects of recession because of its tradition of having strong capitalization and lending practices which are highly conservative in nature. There has been a marginal growth of Canadian economy in the years 2010-2011. By 2005 it is supposed to be able to balance its budget. The petroleum sector of the country is growing at a rap id pace because of the discovery of many new natural oil reserves in Canada. Canada is ranked in the third position in the world with regards to the volume of oil reserves present in the country (CIA, 2012). Financial Sector in Canada – An Overview The financial services sector of Canadian economy consists of banks, loan companies, trusts, insurance companies, credit unions, securities dealers, companies of mutual funds, leasing companies, insurance agents, financial advisors, different types

Rapid growth of technology

Rapid growth of technology EXECUTIVE SUMMARY In the current season, the rapid growth of technology, communication and especially the large volume of information have led many companies and organizations to use IT systems for the management and the safety of information. The main objective of this project is to implement a complete security assessment of the private hospital  «Elpis ». The firms which effectively allocate their resources for the better understanding of the risks they face, can more easily avoid unexpected situations and release resources in other directions and profitable activities (i.e. new investments), that otherwise would have potentially rejected as very dangerous. Therefore, the adoption of procedures that focus on Risk Analysis and Management can substantially help firms to prevent or control risky situations. Once, firms have identified an efficient way to measure the relationship between their risk and rewards they could significantly improve their current operations or find new profitable activities. This project investigates the risks related to the security of the hospital  «Elpis ». Specifically, it focuses on the hospital organization, the sources of operational risks and provides detail description of available technologies that can ensure the management and control of these risks. The hospital is located in Athens having two other subsidiaries called  «Mitera » in Chalkida. We know that the private hospitals interchange important medical information concerning their patients. The central IT department is established in Athens dealing with various services such as the patient registration data, patient diagnoses, management of medical information, other data saving, etc. On the other hand, the IT department in  «Mitera » hospital is obsolete with limited ability to send and receive large volume of data. Therefore, this project aims to investigate all the required procedures that can ensure the integrity and confidentiality of medical information transmission betw een the hospitals and the incessant operation of the IT services.  «Elpis » hospital is constituted by five departments: the Administrative Department, the Human Recourses Department, and Finance Department, the Secretariat-motion of Patient Department and the IT Department, while  «Mitera » hospital is organized into two departments, the Secretariat-motion of Patient Department and the IT Department. We analyse the IT department of  «Elpis » hospital which employs the head of the IT department, a network administrator, a medical software administrator, a database administrator and an information security administrator. Our analysis reveals some rules and practices that can ensure the information safety in the private hospital. Also, we have recognized significant sources of risk come from the outside environment and individuals that work in the hospital. The results of this report can be used in the improvement of medical information safety and the minimization of the possible risks. Next, we present the potential technological solutions that the hospital can adopt at a total financial cost of EURO 5000. They include the Intrusion Detection System (IDS), Antivirus, Spyware, Adware and firewall, Implementation of RAID 5, automatic fire detection mechanisms, emergency generator UPS, automatic Air conditioning control, User policy and Password policy. DETAILED ANALYSIS Description of the companys IT infrastructure In this section, we present organizational structure of  «Elpis » and  «Mitera » hospitals as well as their software part of their network. We continuous our analysis using the CRAMM methodology in order to uncover the threats and weaknesses of the IT departments. Finally, we present possible solutions that can face all these risks relevant with the operation of the IT department. The private hospital  «Elpis » is located in Athens at a building consist of 3 floors. In the first floor we find the hospitals administration and a computer room with the IT equipment. In the second floor is the pathological and chirurgical clinic, the secretariat of the clinics and the medical library. The third floor accommodates the cardiologic clinic, the secretariat of the clinic and the room of telemedicine. All the offices for each roof are connected to the same LAN. The organisational structure of private hospital  «Elpis » is constituted by five departments: The Administrative Department: has the total administrative responsibility of hospital. It applies the strategic decisions and rules which are taken through the administrative council. It aims in the appropriate allocation of responsibilities to employees and to provide the maximum good working environment. It has the responsibility for complaints and the implementation of regulation. The Human Recourses Department: Arrange for any matter relating to the official status of the hospital staff, as well as for the monitoring, organizing and control the personnel of all services of the hospital. The Finance Department: the care for the study of the economic needs of the hospital, and its contribution to preparing the budget of the hospital, making the expenditure, the liquidation of personnel acceptances and remaining compensations, procurement, management and storage of supplies and materials that needed to operate the hospital, the training of balance-sheet and assessment, the responsibility for the safeguarding of hospital fortune and the observation of economic statistical elements. The Secretariat-motion of Patient Department: arrange for any matter relating to the organization of secretarial support according with the decisions of management and other services at the hospital. It arranges the publication of tickets for admission of the sick, and compliance with waiting list admission. Also, it keeps detailed statistics of nursing movement and it grants certificates in the patients, afterwards the submission of relative application. The IT Department: has the responsibility for the organisation and operation of computerisation, processing and maintenance of computerized statistical data, providing and distribution of information in the services of hospital, in the Ministry of Health, Welfare and Social Welfare and in other relevant bodies and each other relevant work. It is responsible to research new technologies with aim to save money and increase productivity of the hospital. It provide technical support and training in the employees of hospital for each technology program that using. Also it is responsible for the security of IT programs and IT hardware. The IT infrastructure of hospital  «Elpis » consists of servers which running the medical application or others services and the ability to store all data, the network equipment (switches-Ethernet) which is used for connecting the computer room-servers and the personal computers of hospital staff and the firewall that is configured from the network administrator and monitor data traffic from the hospital on the Internet with specific criteria. In figure 1 presents the topology of the system. Hardware of Hospital Elpis: A Router (1 piece): The Router is a device which connects the workstation on the network of the hospital. The Router connects the local network of the hospital with the internet, using a leased line of 4 Mbps. Firewall (1 piece): The Firewall is a device or software that prevents access to or from a private network for which it was authorized. The Firewalls can also be applied to hardware and software, or a combination of both. It used to deter unauthorized Internet users from accessing private networks. Also firewall controls the movement of data for the region that is responsible. Switch (4 pieces): a hardware device and used to connect different components in the same network. The switches cutting useless Internet traffic and allow you an affordable high-performance network. The switch is can be used for splitting the physical LAN in two small LANs. In network of hospital this switch splits the physical LAN in two small LANs. A central switch is connected with three other switches which connect the workstations. While another switch connects the servers. Database Server (1 peace): Database Server is a device that used by one or more machines as their database. By using a database server users of the hospital have the ability to manage and organize medical data Web Server (1 peace): O web server is a computer, allowing other computers to access files that manage, using the HTTP protocol (Hyper Text Transfer Protocol). Please note that the basic web server administrator has the ultimate control of the server, unlike a simple user The Hospital uses Apache Server. Mail Server (1 peace): mail agent receives the e-mail from local users (incoming), and offered to surrender on outbound users. A computer dedicated to running such applications is also called a mail server. The transfer of medical results from the Mitera hospital to the hospital Elpis made via e-mails. Backup Server (1 peace): A Backup Server is a way to save your important medical files into one single compressed file. The best part of Backup Server is its affordable and you can transfer the compressed file onto another computer or hard drive. In addition, backup server has the possibility to administrate the tape backup machine. Tape Backup Machine (1 peace): Backup Machine provides the easiest way to backup your critical folders and files allowing access to local and network directories. The disk should be replaced at regular intervals and stored in a sheltered place. Workstastion PC (50): Each office holds, one or more desktop pc only for internal services access and development. Software of Hospital Elpis: Microsoft Exchange Server 2003 Windows XP Professional ORACLE 8 The  «Mitera » hospital has a Secretariat-motion of Patient Department, the Pathological clinic and the IT department. The medical information (patients data, patient diagnoses, etc.) is exchanged between hospitals with web-hosting or email. The communication as achieved with an ADSL 4 Mbps. The technical characteristics (see figure 2) of  «Mitera » hospital are the same with  «Elpis » hospital. Hardware of  «Mitera » Hospital: A Router (1 piece), Firewall (1 piece) Switch (4 pieces) Mail Server (1 peace) Web Server (1 peace) Storage Devices (1): are used to store the medical data. The storage devices are one of the most important components of the computer system. Workstation Pc (5) Staff Members of the group will undertake to conduct the risk analysis in Chalkis hospital. They should be trained in project risk analysis in order to fulfill their goal. Specifically, the team has the following members: Director Management: He has the overall responsibility for the project in order to succeed. He is responsible for proper organization of the team and ultimately responsible for assessing the risk analysis. Chief: He is responsible for organizing team members. Has the responsibility to evaluate the job each team member. He is responsible for implementing the risk management program. Manager system and informations: they have the responsible for the integrity and availability of systems and information Security Department: they have the responsible for security programs and to identify risks and their eliminate with using the risk analysis Security Practitioners: they have the responsible for the evaluation of security requirements for each IT systems. Risk Analysis In the previous section we described the organizational and informational structure of  «Elpis » and  «Mitera » hospitals. Now, we are describing the assets that are classified into three categories: a) software assets, b) hardware assets and c) data assets. A system can be characterized as reliable and safe when it is: a) confidential: provide access only to authorized persons. They have access to important information (medical information, personal patient data), b) availability: the service that the IT facilities provide should be incessant, c) integrity: the system should be ready at any time to provide reliably any information. Also, the information should not change by unauthorized persons. Data assets The hospital manages important medical information. Thus, the access to the internal network should not be free and the communication between the hospitals should be characterized by safety and reliability. The data assets of private hospital  «Elpis » can contain the following: Patient Records: patient personal data (patient medical history) Personnel Records: staff personal data Financial Records: financial data concerning both hospitals Statistics records: statistical data related to the number of surgeries, patient entrances, deaths, etc. In this project, we perform a risk analysis and management for two data assets, the patient files and the statistical data. Hardware assets In this category, it is classified the physical assets like the equipment facilities, buildings. We focus our analysis on hardware assets. Specifically, the hardware assets of  «Elpis » hospital can be the followings: Application server: It is the most important part of the system. The medical application is installed on the application server where the medical data processing is implemented. Moreover, other staff and financial application are installed on the application server. Database server: It makes possible to the different software to ask for information, update and delete data. Backup server: It provide access to different saved data in the system relevant to medical data, patient personal data, staff data, and other general hospital data Mail server: It facilitates the interchange of mails between the  «Elpis » hospital and the hospital in Chalkida. Also, we perform a risk analysis and management for the most important hardware assets: application server and database server. Software assets This category of applications contains software that the staff of hospital uses for data processing. The software assets of private hospital  «Elpis » can be divided into: Staff Software: They are applications that manage data of hospital staff. They permit new records, delete of records and modifications. Patient folders Software: These applications manage data relevant to the patients (personal data patient medical history). Data Statistical analysis Software: They are applications that process statistical data and help in the creation of annual reports DETERMINATION OF COUNTERMEASURES In the above section was realised the analysis for the threats and the vulnerabilities for each assets (figure 3) . In this section we analyze the countermeasures which should be taken for each threat. In addition, we proposed solutions and technical relatively with the physical and hardware section as well as the architectures and security policies. The countermeasures will be supposed in such degree in order that the hospital working in an error-tolerant. Each employee will have the appropriate privileges in system, in relation to the work which he performs. The password policy should be changed. Users must renew the password once a month and use string passwords. For devices that contain important medical information that password should be changed once a week and the rights of the user accounts to be examined by managers every two weeks. As a reference the user policy should describe the rules that will prevent the user from illegal operations (even if accidental) aiming at the confidentiality of data. The company should implement a backup policy in order to store important medical information (patient file) and data which associated with the company (any company, personal information). The backups are major because theres a danger of losing important data from the disaster of equipment or external threats or by human error (deliberate or accidental). The backup will be made every day and in time that the workload of the hospital is small. Also it should be created a monthly backup that will be stored in a separate location, in case where the initial copies have been destroyed by a natural disaster or damage of equipment or human error. The storage of data will be realised with technical of Raid 5 because the price of the disc is significantly reduced and the costs of implementation Raid 5 is now within most organisms budgets. A measure that must be taken is the installation of an emergency generator UPS which will ensure continuous operation of IT equipment even if creates problems at the central UPS. Also an emergency generator UPS should be connected with the cooling system of the computer room. In the computer room there is a simple cooling system which may not ensure the proper operation of IT systems. The most effective measure is the installation of an completed cooling system which will have automatic air conditioning control with aim to minimize the risk of a sudden increase in temperature. The confidentiality and the data integrity is an important part of the hospital. The installation of IDS device provides control of the network and intrusion detection that can come from either inside or outside of hospital and detect violations of security policies. An IDS has the ability to produce reports on the above events. In addition, a measure that must be taken is the installation of completed fire protection equipment in all spaces of the hospital (patient rooms, offices, computer room). The fire system will have the ability to detect smoke or fire and more generally the change in the temperature also in case of emergency the possibility of telephone connection with the local fire station and the police. The education and training of hospital members in safety, confidentiality and organisation issues should are realised each 2 months. Thus, hospital members acquire feeling of personal responsibility and dexterities. Finally, it should be installed Software applications which will protect the network of hospital from malicious programs. The installation of Antivirus Spyware program will take place in server with a view to automatically install and update the antivirus programs on each workstation. CONCLUSION The main objective of this report was to evaluate safety in private hospital Elpis with the method of risk analysis. The hospital has implemented some measures for the correct and safe operation of hardware and software but these measures do not cover many of the threats. The most important areas that should provide the hospital are the confidentiality, integrity and availability of data. These areas should be applied to a greater degree in the user policy and the security policy. Also, it should be implemented specific technologies which ensure in the hospital proper functioning. Access to sensitive patient information and medical research should be protected specifically by unauthorized persons. Finally, it suggested equipment to help in case of emergency.

Piaget Essay -- essays research papers fc

Piaget’s Theory of Cognitive Development   Ã‚  Ã‚  Ã‚  Ã‚  Jean Piaget was born on August9, 1896, in the French speaking part of Switzerland. At an early age he developed an interest in biology, and by the time he had graduated from high school he had already published a number of papers. After marrying in 1923, he had three children, whom he studied from infancy. Piaget is best known for organizing cognitive development into a series of stages- the levels of development corresponding too infancy, childhood, and adolescence. These four stages are labeled the Sensorimotor stage, which occurs from birth to age two, (children experience through their senses), the Preoporational stage, which occurs from ages two to six, (motor skills are acquired), the Concrete Operational stage, which occurs from ages six to eleven, (children think logically about concrete events), and the Formal Operational stage, which occurs after age eleven, (abstract reasoning is developed here).

The focus of this paper will be on the Preoporational stage and how the child’s cognitive abilities develop according to Piaget.   Ã‚  Ã‚  Ã‚  Ã‚  The Preoperational stage is Piaget’s term for the second major stage of cognitive development.

At an early age he developed an interest in biology, and by the time he had graduated from high school he had already published a number of papers. After marrying in 1923, he had three children, whom he studied from infancy.
