In ATM networks there are two methods in traffic control as schemes advancing the quality of service. One is reactive control after congestion and the other which is generally recommended, is preventive control before congestion, including connection admission control on call leel and usage parameter control, network parameter control, priority control and congestion control on cell level. In particular, usage parameter control is required for restricting the peak cell rate of bursy tracffic to the parameter negotiated at call set-up phase since the peak cell rate significantly influences the network quality of service. The scheme for progressing quality of service by usage parameter control is themethod using VSA(Virtual Scheduling Algorlithm) recommended ITU-T. The method using VSSA(Virtual Scheduling Suggested Algorlithm) in this paper is suggested by considering cell delay variation and token rate of leaky bucket, compared VSA and VSANT(Virtual Scheduling Algolithm with No Tolerance) with VSSA which polices violated cell probability of conformed peak cell rate and intentionally excessive peak cell rate. VSSA method using IPP(Interruped Poisson Process) model of input traffic source showed more quality of service than VSA and VSANT methods as usage parameter control because the suggested method reduced the violated cell probability of contformed peak cell rate and intentionally excessive peak cell rate.

Recently, interest in living safety and crime prevention is increasing. The reality is that most women have anxiety about social safety and ultimately want a safe return to home. As a result of these issues, the Seoul Metropolitan Government and the National Police Agency are implementing various services to alleviate them. However, there are limitations such as that the service can be used only during a limited time or the process of checking whether the patrol is really completed is complicated. Therefore, in this paper, we propose a service platform that overcomes these limitations and suggests the best and shortest patrol route to the police based on the desired patrol location applied by citizens. It is designed based on the MVC pattern, and the functions are divided for each user. It is hoped that the platform will reduce crime rates and allow citizens to ultimately return home with peace of mind. Also we expect that the police will ablet to find places where they did not know about or need to patrol with more attention through the recommended route of the platform, which will be helpful in their task.

The purpose of this study is to examine the current congregate meal service program for homebound elderly. One hundred three meal service centers in charge of the congregate meal service programs as part of the elderly foodservice program were surveyed for administrative structure, menu management, food purchasing and production management, hygiene, equipment, and facilities. Statistical data analyses were completed using the SAS 8.1 program for descriptive analysis and ANOVA. The meal cost of 54.4% of the congregate meal service centers ranged from ￦l,500 to ￦l,999 per meal. According to the menu analysis, all nutrients except calcium and Vitamin B2 were at levels of more than 33% of the Recommended Dietary Allowances for Koreans. A total of 81.5% of the centers were operated without the services of a dietitian, and food purchasing, menu planning and other foodservice management processes were handled by non-professionals, such as volunteers, cooks or social workers. Although 88.3% of the centers required a therapeutic diet menu for the health of the elderly, most directors (77.6%) replied that in their current status they could not afford to serve therapeutic diets. These results suggest that financial and systematic supports by government is very necessary. Fifty-five percent of the centers never used standard recipes. For determining portion sizes, 93.2% of the congregate meal service centers depended on the personal experience of the personnel. Finally, the current congregate meal services for the homebound elderly were not operated systematically. To improve the elderly food service program, it is strong1y recommended that it be managed by Professionals.

Objective: The provision of pharmaceutical care service in compliance with good pharmacy practice (GPP) standards is important, but there is lack of studies to investigate the barriers that significantly hinder community pharmacies in Korea from adhering to the standards. This study was aimed to identify the major barriers to provision of pharmaceutical care service in compliance with the proposed pharmacy practice standards which have been developed based on the GPP standards recommended jointly by WHO and FIP. Methods: Questionnaires reviewed by the expert committee were posted for 32 days on the website which is most frequently accessed by community pharmacists. The respondents completed them by checking the scores (Max=5, Min=1) for major barriers to provision of pharmaceutical care service focusing on patient information management and drug use review process in prescription fillings. The answered scores were automatically collected using online data processing. Mean differences between scored data were assessed by ANOVA. Results: Total 321 pharmacists participated in the survey. Results indicated that 'difficulty of diagnosis identification' (m=3.92, SD=1.21), 'lack of time' (m=3.48, SD=1.22) and 'lack of updated clinical information' (m=3.17, SD=1.10) were the major barriers to provision of pharmaceutical care service in patient information management. The main barriers to drug utilization review were 'lack of time' (m=3.32, SD=1.21), 'lack of updated clinical information' (m=3.11, SD=1.17), and 'negative feedbacks or refusals from prescribers' (m=3.00, SD=1.38). There were significant differences among the groups by location, employed number of pharmacists and acceptability to the proposed GPP standards. Conclusion: Difficulties in managing patient clinical information and lack of time were found to be the major barriers in providing pharmaceutical care services in community pharmacies in Korea. Further research is recommended to determine ways to reduce these barriers in order to provide quality pharmaceutical care service that is in compliance with the internationally recognized GPP guidelines.

Background & objective: The Korean government has expanded its benefit coverage to enhance patients' access to orphan drugs and cancer medicines. However, the number of new drugs whose indications were not applied to reimbursement in health insurance was increased. This study aimed to understand the perspectives of experts and various stakeholders on the introduction of a new funding program for cancer treatment and orphan drugs. Methods: We conducted email surveys comprising 19 questions, from September 9 to 26, 2016. We distributed questionnaires to members of the Pharmaceutical Benefit Appraisal Committee and Cancer Assessment Committee. We also conducted a qualitative study through group interviews with stakeholders, including pharmaceutical companies and some patient groups for diseases. Results: A total of 35 survey respondents recommended the introduction of a funding program for orphan drugs, whereas 66% recommended the launch of funding for anticancer drugs. In addition, most pharmaceutical companies and patient groups recommended the introduction of new funding programs targeting patients with cancer and rare diseases. However, some participants asserted that it would be more appropriate to modify the existing reimbursement scheme than launch new funding. Conclusion: This study concluded that introducing new funding needs a social consensus to relieve financial hardships at the patient level.

Under pure P2P environments, collaborative filtering must be provided with only a few service items by real time information without accumulated data. However, in case of collaborative filtering with only a few service items collected locally, quality of recommended service becomes low. Therefore, it is necessary to research a method to improve quality of recommended service by users' context information. But because a great volume of users' context information can be recognized in a moment, there can be a scalability problem and there are limitations in supporting differentiated services according to fields and items. In this paper, we solved the scalability problem by clustering context information Per each service field and classifying il per each user, using SOM. In addition, we could recommend proper services for users by measuring the context information of the users belonging to the similar classification to the service requester among classified data and then using collaborative filtering.

This study, based on current home nursing services, aims at promoting measures for establishing a community-based home nursing system derived from the pilot home nursing demonstration project conducted by the Seoul Nurses Association. The study was based on an analysis of home nursing records from march 1993 to December 1999. The following is a summary analysis, based on individual characteristics of the patients, the organization, which recommended the service for their patients and personnel services. 1. The service has been used by many elderly people 60years of age or older(66.4%). and married people(60.9%). The average number of visits by service personnel for patients of city government was 23.5. This is 2.5 times as many visits by general patients. General patients(20.2%) had only one visit from service personnel, while 65.5% of patients of city government had 10 or more visits. Particularly, for government recommended patients, 72.7% of the patients were recommended by nurses, while only 21.9% where referred to the services by doctors. The main focus of a home nursing service was to maintain present health status (53.4%), and hospice(11.6%). Also to increase hospital-based home nursing services focused on recovery(55.9%) and maintain present health conditions (19.0%). 2. For general patients, 42.0% of patients were suffering from problems related to CVA, 11.3% from high blood pressure, and for patients referred from city, 21.2% from skeletal muscular disease. Results of home nursing services 29.4% of patients were able to recover or maintain their health status, but 48.9% of the patients died. Another main point of community-based home nursing services is medication(6.7%), other basic nursing services(6.1%), special treatment, instructions on how to use medical devices(5.9%), change of physical posture(4.6%), and training on changing physical positions(4.7%). As mentioned above there were some differences between the characteristics of patients who used the pilot home nursing service conducted by the Seoul Nurses Association and those hospital-based service users. The results are believed to be useful to support a community-based home nursing service model. Particularly, patients under medical supervision and patients recommended by government-run health clinics show a higher frequency and longer use of home nursing services compared to general patients or hospital-based home nursing service users. According to the study, nurses accounted for a large number of recommendations for home nursing services. Many patients with CVA, high blood pressure, skeletal muscular disease and bedsores used community-based home nursing services, while others used the service for minor treatments or maintaining their current health status. Based on the study, the researchers make several suggestions to establish a community- based home nursing service system. First, different ways of setting up a community-based home nursing system have to be mapped out based on the evaluation of the pilot home nursing service conducted by the Seoul Nurses Association. Secondly, a new, community-based, home health care nursing service model, and reimbursement payment system have to be developed. This is based on the outcome of the analysis, and implemented policy. Accordingly, efforts are needed to develop a community- based home nursing system with an intermediary role to promote the visiting nursing services of government-run health centers.

Regardless of which country, all public libraries need facilities, collections, and funds. But how well the library system succeeds depends on the staff committed to providing the highest possible level of service to the community. The public library, therefore, should employ the appropriate number of full-time staff. In order to warrant such a work force, this study analyzed the juridical justification, logical validity, realistic fitness, and usefulness of current legal and recommended staffing standards. This study also suggested the revisions of total space of buildings and collection size as crucial variables for library staffing, division of legal service populations, basic staffing level, and additional staff in proportion to service populations for public libraries in Korea.

Purpose: It is recently reported that the increasing noise in the hospitals has caused psychological and physiological stress problems with patients, and medical staffs. This study intends to investigate and analyze the noise levels in the sub stations in comparison with those in the wards in general. This study tries also to find some alterative solutions to the immediate problems. Methods: Noise measurements are conducted in advance prior to analyzing their results at two general hospitals with more than 900 beds, in the comprehensive nursing service wards and in the main/ sub stations located in the general wards Results: Although the noise level in the comprehensive nursing service wards has been slightly lower than that in the general wards, this result is over the recommended noise levels. Therefore it is recommended that efforts should be made to low down the noise level as an alternative and to replace the aged carts as well. Implications: The comprehensive nursing service wards are required to take measures against the various noise sources.
