The main purpose of queueing theory is to find the optimal solution for maintaining systems such as service facilities. Analyzing the overfolw process provides an important information for the solution in queueing systems with finite capacity. In this thesis we approximate the expected time until the first overflow in M/G/1/K/N queueing systems. Results will be applied to approximate the expected time until the first reduction of source population system. Simulation results show that our approximation is applicable to real situations.

An ATMS(Assumption-based Truth Maintenance System) has been widely used for maintaining the truth of information by detecting and solving contradictions in nile-based systems. But the ATMS can not correctly maintain the truth of the information in case that the generated information is satisfied within a time interval or includes data about temporal relations of events in time varying situations, because it has no mechanism manipulating temporal data. In this paper, The extended ATMS method is proposed, which can maintain the truth of the information in the inference system using information changing over time or temporal relations of events. In order to maintain contexts generated by relations of events, the label representation method is modified, the disjunction, conjunction simplification method in the label-propagation procedure and nogood handling method of the conventional ATMS are modified, too.

Serious social problems related to the elderly have appeared in the Gangwon Province because the population in this area is rapidly aging. Gangwon has the highest suicide rate and the highest percentage of single households. In the process of preparing for the super-aging society, Time Bank (TB) System has been actively used in 34 countries, especially in the United States, the United Kingdom, and Japan. In Korea, the Gumi Senior Club has joined this system since 2004. TB is a multilateral exchanged system based on the philosophy that everyone's time is valued equally. Time credits are given to the person who provides social services, such as citizen participation and elderly care. People receive the desired services using time credits or donating them. If this system were applied to the Gangwon Province in accordance with its characteristics, it would help to reduce the elderly's prejudices and manage their diverse health problems. A virtual local currency using IT technologies is needed to boost the regional economy. The elderly's participation in TB is strongly needed. Future research about the effectiveness of health management is then discussed.

The paper addresses the introduction of outsourcing of delivery service for the small service industries such as delivery based restaurant in order to increase the profit and revenue of the service company, upgrade the delivery satisfaction for the customers, and expand the welfare of the senior people through the work. The chinese restaurants are selected as model service companies, outsourcing of delivery services are suggested for those restaurants and simulation models are developed for all operation systems for them. Some of input data for the simulation are collected from the real world and others are refined through the interview with the field workers. 6 scenarios are established considering the number of deliverers and delivery charges and simulation experiments for each scenario have been done according to the 3 kind of situations of the service companies. The results show that introduction of outsourcing increases the revenue and profit of the service company, decreases the service time for the customers and increases the revenue of the delivery outsourcing company employing the senior people. So delivery outsourcing for the service industries can be considered as a good solution for the welfare problem of the senior people.

The purpose of this study is to find some implications for improving diversities of the senior high school system in Korea, by examining those of Australian high school system. Based on the literature review, school diversification can be defined as providing students or their parents with some range of alternative programs from which they can choose a school or program they believe are best suitable for them. In this point, the concept is very similar to that of school choice. The finding of this study can be summarized as follows. First, the programs of within-school diversification at Australian senior secondary schools include subject selecting, extension programs and vocational education and training courses(VET). Second, selective schools, independent schools and specialist schools are the types of between-schools diversity programs in Australia. Third, the characteristic of Australian school diversification was traditionally between-schools diversification, of which the purpose is to provide excellent learning opportunities for some talented students. However, the policy trend has, recently, been extended to within-school diversity programs. The conclusions of this study are as follows. First, the policy of high school diversification 300 in Korea can be seen as a suitable one because one of its aims was to overcome some limitations of the school equalization policy. Second, well defined within-school diversity programs should be considered in order to avoid educational disadvantage issues in education that can be inevitably risen from between-school diversification policies. Lastly, the possibilities of implementing VET programs at general high schools should also be urgently considered.

We aimed to identify personal-interpersonal-social factors influencing Person-Centered Care Competence (PCCC) of senior grade nursing students based on King's dynamic interaction system model. The data were collected using online based questionnaires that contained items on ethical sensitivity, peer group care interaction, interpersonal competence, social support and PCCC. The participants were 242 4th grade nursing students who had undergone clinical practicum. The data were analyzed using descriptive statistics, T-test, ANOVA, Pearson's correlation coefficients, and Multiple regression analysis with the SPSS 26.0. In the multiple regression analysis, interpersonal competence(β=0.42, p<.001) and social support(β=0.29, p<.001) were statistically significant factors that explained 44.1% of PCCC(F=23.77, p<.001). This study is significant in that we identified the factors affecting the Person-centered Care competence based on King's conceptual framework. This study could provide basic data for the development of an intervention program to improve PCCC of senior nursing students.

Purpose: Healthy and balanced meal is very important for the elderly to maintain the quality of life in community. Senior meal delivery system and congregate meal services have been played an important role to prevent premature institutionalization of the elderly. Food delivery system and lunch service spaces for the Korean elderly were mostly focused and limited on low-income family. The purpose of this study is to analyze community food services environments for the elderly in the UK, the U.S. and Japan for the possibility of applying those service spaces to Korean community. Methods: Lunch service spaces of these three countries were investigated by literature research and visiting of venues. Pilot study of the elderly meal services in Seoul was done for comparing environments and future research. Results: Lunch service spaces in three countries were mostly community based for accessibility and the types of management were various for the elderly to choose the most suitable services for them. The group dining spaces are usually small and designed to give de-institutional atmosphere. Implications: Food service environments for the elderly in Korea should develop more community based model of food delivery and congregate meal service spaces as well as more de-institutionalized design of those spaces.
