This paper describes a modeling of service composition manager based on TINA (Telecommunication Information Networking Architecture). The Service composition function is mainly motivated by the desire to easily generate new service using existing services from retailers or $3^{rd}$-party service providers. The TINA-C specification for the service composition does not include the detailed composition procedure and its object models. In this paper, we propose a model of components for the service composition, which adapts a static composition feature in a single provider domain. To validate the proposed modeling, we implemented prototype service composition function, which combines two multimedia services; a VOD service and a VCS service. As a result, we obtain the specification of the detailed composition architecture between a retailer domain and a $3^{rd}$-party service provider domain.

Recently, spread of large amount Smartphones made users to download location-based service applications, which provided by application developers. These location-based service applications are convenient tool for users. Location-based service use technology to find location of user and provide information of user's location. Leakage of information of user's location and expose of privacy life raised new controversy. In this thesis, it will analyze relations of increase of Smartphone market, usage of Location-based service and severity of personal information leakage. Also, it will analyze examples of user's case of damage which caused by leakage personal information and find solutions to reduce damage of personal information leakage. In research, it will find cases of damage that cause by Location-based service. Also it will analyze and research cases of damage and present with graph and chart. In conclusion, to reduce and prevent from damage which caused by leakage personal information, it is important that users and application developers to realize danger of private and personal information leakage. Also, user's personal information must deal with cautiously and application developers have to research and develop the application with powerful security.

In the era of the internet and ubiquitous computing, IS users are still facing a variety of threats. Therefore, a need of more tightened information security service increases unprecedentedly. In this sense, this study is aimed at proposing a new research model in which IT assets (i.e., network, system, and information influence) Security and Information Security Service (i.e., confidentiality, integrity, nonrepudiation, authentication) affect information security quality positively, leading to users' satisfaction eventually. To prove the validity of the proposed research model, PLS analysis is applied with valid 177 questionnaires. Results reveal that both IT assets Security and Information Security Service influence informations security qualify positively, and user satisfaction as well. From the results, it can be concluded that Korean government's recent orchestrated efforts to boost the IT assets Security and Information Security Service helped great improve the information security quality and user satisfaction.

공공 부문이나 대기업에서 운영하는 웹 사이트의 규모가 커지면서 분야별로 사이트가 나누어지게 되는데, 사이트를 이동할 때 마다 로그인을 다시 해야 하는 불편이 있다. 따라서 최근 이용자들의 불편을 줄이기 위하여 SSO(Single Sign-On) 통합인증 체제를 도입하는 사례가 늘고 있으나 전체 패밀리 사이트를 일괄적으로 가입과 탈퇴되는 문제가 발생한다. 이에 이용자의 필요에 따라 선택적으로 가입과 탈퇴가 가능한 통합 인증체제 방안을 제안하고자 한다.

Recently, web-based service software has been used as to combine various information or to share information according to the needs of users and the convergence of specialized fields and individual dependent systems. According to the necessity of the user, the proper service environment and the selective service environment according to the purpose and the needs of the user have been studied in a variety of specialized and combined professional research fields and industries. Software based on cloud systems and web services is being used as a tool for appropriate group and user groups and roles. A service system combined dynamically needs a module to manage a user through internal logic and grant a service access authentication. Therefore, it has been considered various approaches that a user who accesses the system is given a service access authority for a certain period of time. Also, when the deadline is over, the authority that you are given to access system will go through the process of expire the right. In this paper, we define the roles of users who access web services, manage user rights according to each role, and provide appropriate service resources to users according to their rights and session information. We analyzed the procedure of constructing the algorithm for the service according to the procedure of each user accessing the web service, granting the service resource and constructing a new role.

본 연구의 목적은 학교도서관 정보서비스의 범주를 설정하여 정보서비스 현황을 분석하고 활성화 전략을 제안하는 것이다. 학교도서관의 정보서비스 범위와 내용 설정 결과 정보제공 영역과 안내 영역의 서비스 내용이 독서교육이나 교과와 연계한 정보활용교육과정 운영으로 수렴되고 있는 것으로 나타났다. 그러나 2012전국도서관운영평가 결과 학교도서관의 정보서비스 도달률은 48.2%로 매우 낮게 나타났다. 특히 독서상담이나 독서치료 등 학생의 자아탄력성과 학교 참여를 높일 수 있는 정의적 영역과 관련된 정보서비스 내용이 매우 열악한 실정이다. 따라서 학교도서관의 정보서비스 활성화를 위해서는 사서교사 등 전문 인력자원의 지속적인 배치를 위한 제도 개선이 절실한 실정이다. 또한 학교도서관 정보서비스의 핵심 영역인 정보활용교육의 국가 수준 교육과정에서의 위상 강화, 정보서비스에 필요한 기반 확충 노력이 지속적으로 이루어질 필요가 있다. 아울러 독서상담과 치료 등 학생의 스트레스와 문제 상황을 해결하는데 기여할 수 있는 서비스 개발이 필요하다. 그리고 학교도서관 정보서비스가 지역사회와 연계성을 가짐으로써 학교 공동체 활성화에 기여해야 할 것으로 보인다.

Although logistics service quality is considered an essential strategy for success and survival in today's internet environment, there are still a lot of question: what variables determine the extent of logistics service effect, how difficultly do the determinants affecting logistics service effect and how accomplish the decision making in the implementation of inter-organization information system. The purpose of this study is to examine a model to utilize the application and effect of logistics service through e-marketplaces. The results of empirical analysis are mentioned as follows; First, among the interorganization information system factors, four variables(top management support in organization characters, competitive degree in environment characters, relative advantage and information efficiency in innovation characters) have been shown to be primary determinant of the effect of logistics service quality. Second, the type of independent variable used results in a significant difference in the effect of logistics service quality. Third, Korean firms have to pursue the corporate strategy focused on logistics service quality.

BRIS has been established by the Ministry of Agriculture, Food and Rural Affairs since 2011 under Article 21 of the Act on the Preservation, Management and Utilization of Agricultural Life Resources. It is an information service that provides information related to agricultural life resources in connection with the Rural Development Administration, the Forest Service, and Korea Seed & Variety Service, Agricultural Resources and Agricultural and Livestock Quarantine Headquarters. The purpose of this study is to evaluate how the users assess the information system quality (information quality, system quality) for the current Bio Resource Information Service (BRIS). Ultimately, the structural equation modeling analyzes the causal relationship between each variable and how it responds to the user's continuous use intention. As a result, information quality among information system quality and information quality among system quality used as the main variables for the evaluation of BRIS were statistically positively influenced by users' perceived usefulness, while system quality It has been analyzed to have a positive effect on the sustained use intention. The user's continuous use intention is positively influenced by the information system quality and perceived usefulness at a statistically significant level. Especially, the perceived usefulness plays a role in mediating the user's continuous use intention.
