According to the OECD (Organization for Economic Cooperation and Development) report, the suicide rate of senior citizens has been high since 2009 due to lower social participation compared to their youth and depression. As entering the Information Era, it became easier to form and expand relationships due to the influence of online community sites. However, it is difficult to use these community sites for the elderly because they lack accessiblity for seniors. In this paper, we describe the content of community mobile apps for senior citizens' social solitude and participation in information society. We also, analyze why community sites are difficult to use, and suggest community mobile app interfaces and content considering physical and cognitive conditions, focusing on user scenarios based on PACMAD, one of the user assessment models. This will serve as the basis for encouraging the elderly to participate in the information society.

RBAC(Role Based Access Control) has the advantage that reflects the real world because it presents a basic access control model based on user's role in organizations or governments. But in RBAC model, the privileges of the senior roles in these hierarchies are inherited from those of the junior roles, so RBAC model has the privileges problem that he senior are given more privileges than they need. That is, it tends to infringe the Principle of Least Privilege. On the other hand, if we give some excessive constraints on the RBAC model without scrupulous care, it may be meaningless property of role hierarchies. Furthermore, such complicated constraints make it more difficult to mange resources and roles in huge enterprise environments. The purpose of this paper is to solve the problems of role hierarchies such as inefficient role managements and abuse of privileges by using newly presented the backward tag pointer path expression in the inheritance of privileges.

Due to the shortage of elderly care services in urban areas, multi-functional welfare facilities are proven to be very effective for delivering various service needs of elderly in Japan. Introduction of new longterm care policy for elderly in Korea would change many aspects of elderly care service facilities. Especially elderly home care services like adult daycare centers will expand drastically after beginning of elderly longterm care insurance. The purpose of this research is to study and analyze multi-functional welfare facilities in Japan focusing on the types of day service in those facilities. Planning of daycare centers in multi-functional welfare facilities for the elderly can be classified to 8 types. Those types are daycare centers with senior housing, longterm care insurance facilities, senior centers, small multi-function facility, medical facilities, educational facilities, community facilities and general housing projects. Each type has different benefits for the networking of services for the elderly. Design of daycare centers in multi-functional welfare facilities have distinctive features in entrance and user approach, space allocation and circulation planning. The study of daycare centers and multi-function planning should be followed to make better home care environments for the elderly in Korea.

In the cases of the major cities, high poverty rate of the elderly, immature pension policies, and insufficient market conditions, policies and services for the employment of the elderly decrease the desire for the job participation. It is time to prevent the problems of the elderly, and induce the reachable seniors to participate in social activities. This research provides the location-based, customized job-search service for the elderly in order to actively support the participation in the economic activities of the elderly. The goal of SSJS(Smart Senior Job Search) is to provide the individual elderly with the customized position. It prints the appropriate positions near user location based on the residential area, job classification, and the physical condition, and provides the mash-up of the selectable job range in the unit distance based on the map. This customized service, which enables the seniors to select the type of the jobs based on their physical, mental and life conditions of the seniors, supports the participation in economic activities of the elderly people, and contribute to the expansion of the social job positions for the elderly and the equalization of the local development.

This study examines the case of living lab led by intermediary and explores the development possibility as living lab platform. The analyzed cases are 'The Seoul Innovation Park Living lab', 'Korea Senior Living lab' of Seongnam Senior Experience complex, and 'Disaster Safety Living lab'. As a result of the analysis, all three cases have formed a user panel to form a living lab platform, and provide living lab service to internal and external organizations. A common feature that combines a technology platform with a 4Ps-based governance platform is identified. However, the characteristics, the meaning, and the process are different from case to case. In the future, the living lab platform needs to share learning experiences that are going on individually, since domestic living lab platform is in the early stage. Through this, it is necessary to seek collaboration and cooperation with related similar projects, and to jointly promote institutional and physical infrastructures related to living labs.

This study, continuing education programs and elderly welfare center in order to verify the source of satisfaction perceived elderly welfare center services for the elderly aged 60 or over to use the various welfare services for elderly, distribute the questionnaire with the permission of the welfare centers, utilizing a material portion 175. This study used PASW 18.0 program on the collected data and for data analysis, detailed statistical analysis methods used were t-test and One-way ANOVA. Gender were observed in higher overall satisfaction of a man, granted a high degree of satisfaction lower age, education elementary school, at least university graduates, found that satisfaction is high. In health, become clear that the more satisfied the more you health, spending money a month it became clear that the more satisfied the elderly to be used about 300,000 won to 500,000 won use period found that the elderly were more satisfied if less than one year and more than three years. In the region, Gangseo-gu is found to be slightly higher overall satisfaction with services than the Eunpyong-gu.

Role-based Access Control(RBAC) model has advantage of easy management of access control with constraints such as permission inheritance and separation of duty in role hierarchy. However, previous RBAC studies could not properly reflect the real-world organization structure with its role hierarchy. User who is a member of senior role can perform all permissions because senior role inherits all permissions of junior roles in the role hierarchy. Therefore there is a possibility for senior role members to abuse permissions due to violation of the least privilege principle. In this paper, we present a new model of role hierarchy, which restricts the unconditional permission inheritance. In the proposed model, a role is divided into sub roles(unconditional inheritance. restricted inheritance, private role), keeping organization structure in corporate environment. With restricted inheritance, the proposed model prevents permission abuse by specifying the degree of inheritance in role hierarchy.

This study attempted to find ways to recognize public libraries as social institutions with spatial functions to integrate generations for older adults in the face of Korea's entry into a super-aged society. In particular, the goal of this study is to find out the implications and strategies for the design of libraries and facilities for older adults. And to this end, major guidelines related to senior citizens' service spaces and facilities were analyzed to derive implications for senior citizens' services. In addition, an in-depth interview survey was conducted on elderly users with experience in using library services to identify the priorities of creating spaces and facilities for the elderly. As a result, "Open elderly service space" and "Integrated elderly service space" were proposed as a way to organize the elderly service space in public libraries.

Recently, owing to performance elevation of telecommunication technology, increase of wireless internet's subscriber and diffusion of wireless device, Interest about LBS (Location Based Service) which take advantage of user's location information and can receive information in concerning with user's location is increasing rapidly. So, MOMS (Moving Object Management System) that manage user's location information is required compulsorily to provide location base service. LBS of childhood such as service to find a friend need only current location, but to provide high-quality service in connection with Data Mining, CRM, We must be able to manage location information of past. In this paper, we design distributed manage system to insert and search Moving Object in a large amount. It has been consisted of CLIM (Current Location Information Manager), PLIM (Past-Location Information Manager) and BLIM (Distributed Location Information Manager). CLIM and PLIM prove performance of searching data by using spatiotemporal-index. DLIM distribute an enormous amount of location data to various database. Thus it keeps load-balance, regulates overload and manage a huge number of location information efficiently.
