As growth of the web-based applications, the requirements of the users who have been very familiar to the web-based user interfaces and customer-oriented services on the Internet would become more knowledge-intensive and higher technology involved in a more convenient and polite way of service delivery. Therefore, the service quality of information system department should be considered as a very important factor influencing success of information systems. The objective of this study is to provide the relationship between service quality of IS department and its impacts such as use, user satisfaction and job performance. For this purpose, we provide a research model for it and test it empirically for the users of the corporate portal in one of main telecommunication service providers in Korea. In result, our model with satisfiable validity and reliability shows not only importance of IS departments' service quality but also two-faced characteristics of service quality. That is, while technical competence which means with knowledge and expertise of IS department staffs is more related with user satisfaction on information systems, personal service which means the way and manner of service delivery is more related with use of it.

According to software growth, also software maintenance has been continuously improving. In addition, the existing concept of software maintenance process demands operational management and improvement of service task. However, when we perform maintenance task, we have several constraints about applying service based requirement to system. Therefore, in order to solve these problems, we need a study of task of process for service based maintenance. In this paper, we propose a Service based Software Maintenance Process. Proposed process based on MaRMI-RE standard for software development and maintenance and compares it with the service based representative standards. In a related works, we study activity of ITIL and identify activities and tasks for maintenance. After this, identified activities and tasks compare with activities of MaRMI-RE. And then, we derive activities and tasks of a Service based Software Maintenance Process. Finally, we validate a result by comparing the proposed process with a general service operational process.

The study is to investigate the extent to which public sector and private sector have established local governance at the community level. Also, it examines similarity and dissimilarity in the perception of unmet needs in the community service delivery system among local officials and workers in social service agencies for poor female-headed households, using survey questionnaire. It finally aims to propose more effective way of local governance between officials and workers in service agencies, and to improve living conditions for poor female headed households. Results show that first, about 70% of survey participant assess community governance and network system do not work well. Second, the more positive people evaluate their outreach efforts and the network level among community service agencies, the more they perceive that unmet needs are satisfied and recipients are well benefited. Third, the perceptions are significantly different in the extent of service delivery and the unmet needs between local officials and service workers who implement direct social service to female-headed households, after controlling for other related factors. In conclusion, suggestions are given to develope more effective service delivery system for poor female-headed households.

To solve the internal security problem such as human error and bad faith, the automation of computer system management is significant. For this purpose, we focus attention in the automation of Mail Delivery Service. Today, requirement for reliable mail delivery system becomes larger and larger. However, existing systems are too strict about their configuration. Hence, we propose the method based on Reinforcement Learning (RL) to achieve proper MX record ordering. A measure on validity of the design of system, such as network topology number of servers and so on, is also obtained as side benefit. In order to verify the usability of the presented method, we did on a small model of mail delivery system. As a result, we show that RL is available for determination of the proper MX record ordering. Additionally, we suggest that it is also available for comparing validity of setting of MTA and the network design.

The purpose of this paper is to review concerns and activities related to the library of Germany as well as to look over recent trends referred to the maintenance of the library and its information service system since the unification of Germany in 1990. In fact, since the unification, many libraries in old East Germany have been closed with some precious books being lost. Also since most of libraries are short of funds and proper materials, it is real situation that they can not actively respond to the demand of information by library users who want to adapt themselves to changes, while only urgently requesting some support from old West Germany. In the meantime, the new government and libraries of Germany are giving a great effort to building an efficient document delivery system through financial support for the expansion of books and the purchase of urgently necessary library equipments in the poor libraries of old East Germany and support for the course to re-educate the in-service or unemployeed librarians, and also systematic organization between similar libraries, integration of national bibliographies, and maintenance of the interlibrary loan system. The nationwide interlibrary loan system, an expanded form of the system of old West Germany, allows the delivery of document to be easily performed, centered on both central cataloues for East Germany and West. However, in order to build an efficient information service system which covers whole Germany, it seems there needs more time required.

Due to the development of IT technology and the spread of infectious diseases, online non-face-to-face services are rapidly expanding. In particular, the information delivery process is also changing from the past postal branch-based to an information delivery system using mobile devices. This change is due to the change from the information delivery using the telephone line to the information delivery system using the Internet. Mobile notification service is a service that sends electronic notices to mobile devices held by users to deliver information and is validated for delivery, which has the advantage of reducing the benefits of unnecessary mail production, exposure to personal information, and misdelivery. However, user identification information must be provided to operators that provide mobile electronic notification services. In this paper, the current state of use of the mobile electronic notice service, which has been in effect since 2019, is investigated and analyzed, and the current mobile electronic notice service is to be safely provided and to take appropriate protection measures for personal information. In providing the mobile electronic notification service to users, it is possible to identify the service standards required by the sending agency, and based on this, prepare the technical standards for the mobile electronic notification service that the sending agency must comply with in advance and use it for the mobile electronic notification service.

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.
