The initial research of Task Computing in the ubiquitous computing (UbiComp) environment revealed the need for access control of services. Context-awareness of service requests in ubiquitous computing necessitates a well-designed model to enable effective and adaptive invocation. However, nowadays little work is being undertaken on service access control under the UbiComp environment, which makes the exposed service suffer from the problem of ill-use. One of the research focuses is how to handle the access to the resources over the network. Policy-Based Access Control is an access control method. It adopts a security policy to evaluate requests for resources but has a light-weight combination of the resources. Motivated by the problem above, we propose a universal model and an algorithm to enhance service access control in UbiComp. We detail the architecture of the model and present the access control implementation.

We consider a G/M/1 queue with two-stage service policy. The server starts to serve with rate of ${\mu}1$ customers per unit time until the number of customers in the system reaches A. At this moment, the service rate is changed to that of ${\mu}2$ customers per unit time and this rate continues until the system is empty. We obtain the stationary distribution of the number of customers in the system.

With the rising attention dedicated to research ethics, the responsibility of researchers to comply with research ethics is also highlighted. Among a number of research ethics obligations that researchers should abide by, an institutional review board (IRB) review is the most essential step to be taken before launching research. As the health service research field grapples with human subjects, it closely aligns with IRB deliberation. However, it seems that researchers still do not fully understand their obligations of IRB reviews. Due to the nature of health services research, there are many cases that are exempt from IRB reviews, which often elicits confusion in the research field. On that note, we aim to explore the issues regarding IRB reviews that health service researchers need to know.

Purpose - This study focuses on "large-scale marts," which is a typical discount-based retail channel (hereinafter, DRC), and provides practical managerial implications by applying the KD-SQS service quality factor based on customers' experiential perspective by developing and applying existing service measures. Research design, data, and methodology - The research subjects include adults who have experienced "large-scale marts." The research involved SPSS 20.0 and AMOS 19.0 packages; path analysis is used to analyze structural relationships. Results - First, physical aspects, human interaction, and additional convenience aspects of service quality have statistically significant influence on service value. Second, physical aspects, human interaction, and policy have statistically influence on store loyalty. Third, service value influences store loyalty. Fourth, service guarantee adjusts the relationship between service quality, service value, and store loyalty in terms of human interaction and policy. Conclusion - Among service quality measures, improving service value through personal service needs to be prioritized, while we need to develop different methods for the service guarantee system to effectively influence service value and store loyalty.

At present, deterioration in service quality, which caused by increased network traffic from a lot of users in the same network, makes smooth communication service difficult. In this paper, we present policy-based QoS management system for VoIP service in order to supply smooth VoIP service to users. The presented system can guarantee quality of VoIP service even in huge traffic situation, and makes it possible to operate whole network in an efficient manner.

The purpose of this study is to examine internet agent of IT(Information Technology) in health care industry Since IT is essential for corporate strategy in service management, this section examines IT in health care service, especially from the view of 'Agent Technology' that has been recently issued. Intelligent agent is a new paradigm for developing software applications. More than this, agent-based computing has been hailed as 'the next significant break-through in software development' and 'the new revolution in software'. And health care service is a non-mechanic, human-based service. This paper reviewed what possible suggestions or advices can be made to the health care service. Since many health care services using internet have been attempted over the recent years, this study will hopefully be able to come up with good suggestions from many aspects. Thus, information inequality between producer(physician) and consumer(patient) in health care service will be decreased through the introduction of agent technology.

Background : Demands have increased for a variety of welfare services and customized services for persons with disabilities(PWD). A management System focused on PWD was needed to provide for comprehensive services. The purpose of this study was to design a disability database and an application system in order to provide continuous and comprehensive rehabilitation service for PWD. Methods : We analyzed local and abroad disability-related policies and systems and derived the contents that should be included in the integrated database for PWD through a survey among rehabilitation specialists. Result : The integrated database for PWD was composed of 7 categories including General Characteristics, Health & Medicine, Assistance, Education, Employment, Economics and Daily & Social Life. The applicable system of integrated database for PWD was proposed to help conducting policies in such areas as follows ; 'welfare', 'education and culture', 'economic activity', 'social participation' and 'Health'. Conclusion : The main goal of disability policy and strategy should be established by systematically analyzing disability-related data integrating database of PWD. Accordingly, specific objectives and directions for disability policies should be set and efficiently managed and operated. The integrated database for PWD may be utilized for disability-related policies and service monitering, sustainable and integrated management and community participation and integration based on the rights of the disabled.

This study focuses on the determinants of the community health service utilization. Theories suggest seven models for community health service utilization, which are divided largely into two groups such as Health Service Supply Model and Health Service Demand Model: Supply Model includes Medical Implements Model, Personnel and Budget Model, Management System Model, Staffs' Behavior Model, Service Quality Model; Demand Model includes Area Model and Clients' Characteristics Model. This paper tests how the above models influence on the community health service utilization. After interviewing some administrative staffs of the Community Health Service Center at Pusan, questionnaires were made and mailed to the staffs of 198 Korean Community Health Service Center as a universe, among which from 98 centers we got response. Analyzing the data from the questionnaires, we found "the number of personnels in the health service center" and "demands for medical service" as important variables to affect the utilization of the community health service center. These two variables are typical factors representing Supply Model and Demand Model each. However, the variables selected from Management System Model, Administrative Behavior Model, Service Quality Model and Area model are not significant in a statistical sense. The paper suggests that to recruit the personnels, especially nurses, and to make out the demands of the clients for health service be the precedent conditions to increase the utilization of the Community Health Service Centers in Korea.ce Centers in Korea.

The scale and the extent of a aging of population of a rural are more serious than those of a urban in China. However, the welfare policy and the service for the aged in the rural are inferior. China established the different systems of social welfare policy for the city and the rural and has administered it since the china was established. Owing to an open-door policy(opening of a reform) the gap between the two got more deeply distinguished. Accordingly. the striking difference is shown in a living environment and a quality of life of the cities and the rural. I made clear the difference of services for the aged in the rural and the urban examining daily lives, medical industry, recreation systems and so on and analyzing their sources. In addition, I proposed the ways to establish synthetic social welfare policy of the urban and the rural.
