Mobile communication is evolving toward next generation system that is capable to provide ubiquitous human-centric services with giving no restriction on time and location. In particular, context-awareness will be realized using various sensors and devices and related technologies under the ubiquitous Next Generation (NG) mobile communications environment where user's demand and surrounding context are changing dynamically. By such context awareness, context aware service which provides best suitable services for a user by analyzing user's needs and situational information, will be one of the promising NG mobile services. In this article, we propose NG mobile service environment with focusing on generic service traffic flows supported by the NG service platform which gives various means of connecting users and service providers. Then, we propose evolutional phases of context-aware services based on ranges of context information and evolutional trend of telecommunication technologies and networking environment in NG mobile service environment.

The purpose of this study is to analyze the spatial distribution and the linkage characteristics of the warehousing industry in Busan and to provide the policy implications for the warehousing industry in Korean port hinterland. We surveyed the warehousing firms in Busan. Categorizing the warehousing industry into industry types, sizes, and organization types on the basis of the survey, we attempted the point pattern analysis and the proximity analysis using the GIS. The warehousing industry in Busan had changed from a small single-unit firm to a medium or a large firm with a head office or branches. These were distributed in hinterland of North Harbor, South Harbor & Gamcheon Harbor, and Sin-Pyoung & Jang-Rim industrial complex and Sasang Industrial Complex constituting the spatial agglomeration. The warehousing industry in Busan formed the linkages with other sectors of the same logistics to provide manufacturing industries with various other services as well as storage services. The linkages were largely formed in the local scope with spatial proximity, generating the economic gains of agglomeration, which were transformed into the efficiency of the warehousing industry in the local scope to gradually expand the spatial dimensions of the linkages.

In this study, in order to practice the social inclusion of libraries, the related policies currently announced in the 3rd Comprehensive Library Development Plan were examined, and the current status of tasks promoted by central administrative agencies and metropolitan and provincial libraries was examined based on these policies. As a result, first, in terms of active information welfare realization, various programs and services are being implemented to bridge the knowledge and information gap, but it seems that the scope of the target should be expanded in the future, cooperation with related organizations, and infrastructure improvement. Second, in terms of expanding the openness of the space, the expansion of the open space as an open space and the application of universal design are being performed. In the future, it seems that the scope of universal design application should be expanded in consideration of budget investment for continuous space reconstruction and diversity of users. Third, in terms of linking services across boundaries, services and programs are provided to infants and toddlers, children, women, the elderly, the underprivileged, job seekers, and multicultural families. In the future, it seems that the improvement of the service system for the expansion of inclusive services in libraries should precede, and cooperation between related ministries should be made to provide differentiated services. Finally, it is expected that future policy-making tasks for social inclusion should be considered not only for books, programs, and spaces, but also for librarians' education, establishment of cooperative networks with related organizations, and marketing for services and programs.

Applications in ubiquitous environments should provide the best services to users by considering the changes of users requirements and service environments, and should adapt service behaviors to the underlying platform's behaviors according to contextual changes. To reflect users requirements actively and provide more flexible services, we propose 2-level context adaptation method for supporting dynamic application adaptability in contextual changes. We offend the range of contexts to users requirements for supporting context adaptation. It can reflect users preferences in offering application services. For application adaptability, we use adaptation policies to allow applications require how they adapt to specific contexts, and to make them react actively on such situations.

In developed and industrialized countries life expectancy has increased significantly over the past century. As a consequence, the proportion of elderly individuals in these countries has also enlarged with the resulting increased burden on health care providers. In many developing countries the problem of age related and other eye disorders has far outstripped the ability to manage them. Accordingly, the World Health Organization (WHO) has introduced an initiative: Vision 2020 - The Right to Sight, with the objective of eliminating preventable blindness by the year 2020. This paper reviews the broad range of conditions involving external and internal structures of the eye and also the effects of aging on visual functions. It is hoped that this will provide a stimulus for increased study of these disorders, improved clinical diagnosis, and an enhanced interest and role in contributing to the objectives of the WHO and the World Council of Optometry with respect to early diagnosis, prevention and management of the diseases and disorders of the eye that are more prevalent in old age.

The present study has been conducted to investigate the validity of the computational fire model and the results predicted by BRANZFIRE zone model and FDS field model are compared with a real scale fire test with spray fire in a multi-compartment. The liquid spray fires fueled with toluene and methanol are used as the fire source and the quantitative measurement of heat release rate is performed in an isolated ISO-9705 compartment with a standard door opening. The temperature field predicted by FDS model showed good agreement with the measurement in the fire room and the corridor, and BRANZFIRE model also gave acceptable result in spite of its simplicity and roughness. The mean temperature predicted by FDS model corresponds with measurement within maximum discrepancy range of 25% and the overall mean value of FDS model matched well with experimental data less than 10%. This study can contribute to establish the limitation and application scope of computational fire model and provide reference data for applying to reliable fire risk assessment.

The range of Internet usage is drastically broadened and diversed from information retrieval and collection to many different functions. Contrasting to the increase of Internet use, the efficiency of finding necessary information is decreased. Therefore, the need of information system which provides customized information is emerged. Our research proposes Web Service based recommendation system which employes inference engine to find and recommend the most appropriate products for users. Web applications in present provide useful information for users while they still carry the problem of overcoming different platforms and distributed computing environment. The need of standardized and systematic approach is necessary for easier communication and coherent system development through heterogeneous environments. Web Service is programming language independent and improves interoperability by describing, deploying, and executing modularized applications through network. The paper focuses on developing Web Service based recommendation system which will provide benchmarks of Web Service realization. It is done by integrating inference engine where the dynamics of information and user preferences are taken into account.

우리나라도 2000년 들어 65세 이상의 노인인구는 7.2%를 넘어서서 본격적으로 고령화사회(aging society)에 들어섰다. "21세기는 고령자의 세기"가 된다고 해도 과언이 아니며, 2019년에는 14%가 넘어 고령사회(aged society)로 진입할 전망이다. 그러나 우리나라는 "고령자의 세기"라고 불릴 만큼 사회구조가 변화하고 있는 시점에서 노인 인구의 0.3%만이 시설에서 보호를 받고 있으며, 나머지 99.7%는 일반가정에서 생활하고 있다. 유교사회의 전통규범에 의해 99.7%의 노인들이 가족에 의해서 그들의 노년을 보내고 있으나, 핵가족화와 산업화에 따라 윤리규범이 깨어지고 있는 탈윤리시대에서, 더 이상 요보호 노인(와상노인, 중풍노인, 치매노인), 장애노인 등의 수발 및 보호는 윤리적 규범이나 가족, 가정에 의해서 충족되기는 점차 어렵게 되어 가고 있으며 극명한 한계를 보이고 있다. 이러한 사회적 상황과 가족부양체계의 변화는, 고령자를 대상으로 하는 각종 복지 시책 개발, 특히 재가노인 복지서비스의 필요성이 제기되고 있으나 우리나라는 아직 미미한 수준에 머물러 있다. 우리나라 재가노인을 위한 정책의 활성화와 서비스의 양적 확대 질적 고도화를 위해서는 첫째, 보편적으로 이용할 수 있도록 대상 범위를 확대해야 한다. 둘째, 의료서비스의 확충과 같은 전문적 서비스의 확대 실시가 요청된다. 셋째, 동일한 서비스내용에 대해서는 전달체계를 일원화할 필요가 있으며, 사업주체별로 역할을 분담하고 담당 인력별로 업무를 분담해서 전문성을 강화해야 한다. 넷째, 재가복지 서비스는 중앙과 지방의 분담에 의한 무료 서비스인 만큼 지원을 획기적으로 개선 나가며, 보편적 이용의 정도가 큰 서비스는 점차 정부지원의 서비스로 확대하되 저소득층에 대하여는 무료서비스를 제공하고 저소득층 이상에 대해서는 소득 수준에 따른 차등적 서비스 요금을 부과하는 것이 바람직하다. 그리고 보다 질 높은 서비스를 원하는 중산층 이상에 대하여는 시장 경제원리에 의한 실버산업이 활성화되어야 하며 일본에서 시행하고 있는 개호보험제의 도입방안도 적극적으로 검토되어야 할 것이다.
