The purpose of this study was to examine the image perceived by fathers of children with Internet addiction. To achieve the study purpose, we conducted depth interviews with ten fathers of children with Internet addiction who had been diagnosed as At-Risk through a face to face meeting. The reason for choosing face to face interviews was to listen to the subjective stories and descriptions from fathers about the kind of fathers they are, which are felt and experienced in real life. More specifically, we selected the depth-interview methods through structured questions and non-structured questions. The interviews were held for two or three hours through an individual meeting of ten fathers and data were collected in order to conduct a categorical analysis. The figures discovered from fathers of children were divided into four categories; the father figure who is indifferent to the Internet use of his child, the father figure depending only on education through the Internet, the father figure who is in a weaker point than the Internet and the father figure who is addicted to the Internet. Based on the study results, we suggested the desirable behaviors, which may be useful for both fathers and children with Internet addiction as well as a follow-up study.

Recently, community computing has been proposed for group formation and group decision-making. However, legacy community computing systems do not support group need identification for ad hoc group formation, which would be one of key features of ubiquitous decision support systems and services. Hence, this paper aims to provide a multi-agent based methodology to enable nomadic community computing which supports ad hoc need identification and group formation. Focusing on supporting group decision-making of relatively small sized multiple individual in a community, the methodology copes with the following three characteristics: (1) ad hoc group formation, (2) context-aware group need identification and (3) using mobile devices working in- and out-doors. NAMA-US, an RFID-based prototype system has been developed to show the feasibility of the idea proposed in this paper.

The main characteristic of technology commercialization by technology-intensive SMEs is that its success is highly uncertain due to the low maturities of their technology and market. Therefore, in order to find out more effective policy, it is essential to understand the technology commercialization in terms of the institutional support system including innovation policy, rather than an individual firm's strategy. Focusing on the Daeduk Innopolis, where many technology-intensive firms agglomerate, this paper explores SMEs' behavior for technology commercialization and the innovation system in the regional level. Then it points out the limitations and problems of the technology commercialization system in Daeduk innopolis, which might be closely related to the 'system failure' in the transition period. Based on the results of this innovation system approach, this paper also suggests some policy directions and agendas for overcoming those system failures in technology commercialization.

Mind map is a very useful technique for brainstorming. Therefore, it can be effectively used for collaboration as a creative group conception. However, existing mind map software is not possible to collaborate because it is difficult to share mind map or discuss among members. In this study, we developed a mind map system that can support collaborative work as well as individual authoring and editing. This can incorporate individual mind maps of members into mind map of team, share and discuss them, and modify the mind map. This is convenient because it does not require a separate program installation, and verifies usability to support the process of collaborative process through usability evaluation.

The purpose of this study is to examine the relationships between fathers and children with Internet addiction. To achieve the goal, researchers chose face to face interview methods with 12 children who had been considered'at risk'with Internet addiction. More specifically, examiners conducted individual in-depth interviews with 12 children associated with Internet addiction for 30~40 minutes during four sessions through structured questions and non-structured questions. After collecting data, examiners conducted a categorical analysis based on collected data. Finally, the research results, discovered in this research, were as follows: First, the Internet set up the inter-generational barrier in the relationship between father and child, second, children took an interest in the Internet instead of their busy father, Third, the Internet played the role of a place to escape from the awkwardness with their father, fifth, fathers were not able to control the Internet use of their children. Based on the research results, this study suggests a desirable behavior pattern for fathers which can be conducive to children with Internet addiction and their fathers along with a follow-up study.

The study aims to reveal the factors that impact the decisions made by child care directors in the process of managing their day care centers. The seven participants I surveyed are directors in child care centers located in Seoul and Kyung Ki-Do. Through in-depth interviews and case-by-case studies, I uncovered that there are both external and internal factors that influence a director decisions. The external factors are following the standards set by the law, accommodating the demands set by parents, collaboration with the teachers, accepting the advice of friends and family, and creating realistic conditions. The internal factors are each director's own management philosophy, religious beliefs, and personal experience. This study aims to create policies for establishing and developing educational material so that child care directors will be able to provide an ideal environment for the supervision and education of children.

This study aims to seek effective measures centering on developing countries that can export Korea's e-Government ranked the first place two times in a row (2010 and 2012) in the United Nations' e-Government Survey. Up to the present, individual ministries or agencies have made efforts to export systems or services related to e-Government, but it is judged that comprehensive and systematic approaches have not been sufficient. This study, therefore, has been intended to find realistic mid- and long-term strategies and supporting methods that can promote Korean-type e-Government exports by analyzing problems identified in the strategies implemented by the current ministries or agencies for assisting enterprises engaged in e-Government exports. In addition, this study as an empirical one has been intended to diagnose improvement points by analyzing e-Government exporting strategies executed by existing government ministries and agencies, suggest methods for filling in gaps between as-is and to-be models, and seek timely and effective measures in the future.

IR(Institutional Repository) is an indispensable instrument for not only long time preservation of intellectual products but also for shifting commercial publishing company-dominated academic communication stream. In Korea, dCollection project of Ministry of education, science and technology has contributed on immediate, integrated circulation of distributed research products. dCollection is already one of the few integrating instrument for distributed academic resources, but it has not been university's voluntary instrument to announce their research accomplishments and to realize open access. On the other hand, Japanese government has promoted universities' IR operation through "Next generation infrastructure construction project." Even though distributing speed is relatively low, each university made ripe operating skill by their selves and realize its own purpose. This study comparatively analyzed policy and current status of Institutional Repository in Korea and Japan from various viewpoints. And also it proposed directions of development about Korean Institutional Repositories.

Over the past decades, information and communication service providing safe and efficient navigation have been tried in maritime area. However, there were provided different ways such as different protocol or different policy. It made hard to serve efficiently. The introduction of MSI as a part of e-navigation development can be a kind of concepts to solve this problem. This paper tries to suggest a conceptual design of onboard application middleware to be able to communicate the shore-side maritime safety information system, take into account the reuse of open-source software.
