The current education is becoming more extensive with the application of various teaching methods. This is a problem that is so distributed that it is difficult for users to find the data and it takes a long time to find the information they need. Currently, various educational services, materials, and instruments are developed and scattered. Therefore, it is important to raise students' awareness of aptitude and career path with customized education tailored to students. Conventional education platforms have very difficult to choose the right materials for students because of the spread of educational programs and institution materials. To solve this, we propose a customized recommendation approach to recommend customized educational service materials and institution for students to teachers, which helps teachers conveniently choose materials suitable for their respective environments. On this new platform, the CNN algorithm provides recommended content for classes and students. For real service on the educational service platform, we implement this system for Jeil edus business. Through this mechanism, we expect to improve the quality of education by helping to select the right service.

Social networking services (SNSs) serve to strengthen people's social relationships by providing ways for people to utilize such relationships especially like workplace. With the development of the internet worldwide, the number of SNS users is rapidly growing and a wider range of service types have become available. In this study, we designed a research model with a focus on what makes people use SNSs at workplace and how it is associated with changes in relationship quality and their intention to continue using the services and analyzed data collected for the research model. Theoretically, intrinsic and extrinsic motivation was invoked and measured, in terms of hedonic and utilitarian values, and satisfaction and trust were adopted as variables of relationship quality. Data were collected from Facebook users using workplace, and a partial least squares (PLS) analysis was made on 188 data points. The analysis results showed that two forms of motivation-hedonic and utilitarian-are separated from each other in their influence and that utilitarian value is more important than hedonic value, especially when it comes to users' satisfaction. In addition, the analysis found a weak relationship between satisfaction and trust in SNS environments; this was a little different from the results of previous studies.

To ensure competitiveness in the modern automotive market, material arrangements and information managements should be performed concurrently with new car developments. In automotive general assembly shops, thus, new business workflow and supporting environments are inevitable to reduce the manufacturing preparation time in developing a new car in the manner of concurrent and collaborative engineering. Since complete material arrangements for a whole general assembly system is a huge and complex job, several planners should execute their planning jobs and share information. Therefore, each planner should provide others with his/her results with continuous on-line communication and cooperation. Digital automotive general assembly factory is useful the performing concurrent and collaborative engineering and is essential for material arrangements and information managements systems. In this research, we constructed a sophisticated digital factory of an automotive general assembly shop by measuring and modeling through the parametric 3-D CAD, and a web-based system for concurrent and collaborative material arrangements for automotive general assembly via 3D mock-up is developed. By the digital general assembly shop and developed web-based system, savings in time and colt of manufacturing preparation activities are possible, and the reliability of the planning result Is greatly improved.

This research analyzes results and efficiency to promote a government enterprise of A Korean public enterprise to use DEA. Especially, we were used analysis efficiency which are one is year-on-year, another is integrated, and the other is vertical analysis. As a results of integrated analysis show that Gyeonggi_2003 Gyeonggi_2004, Gangwon_2004, Chungcheon-Bukdo_2003, Chungcheon-Bukdo_2004, Cholla-Namdo_2005, and Kyongsang-Bukdo_2003 need to improve upon. Year-on-year analysis result that Gyeonggi, Gangwon, and Kyongsang-Bukdo need urgent improvement. Today, many advanced countries approach not only agricultural investment but also synthetic investment because they believe that agriculture contains living space including food control. Therefore, when the government make a strategic plan for the land and water development in the field of agriculture, they should prepare it well including the proper measures to cope with the internal and external environments.

This study was performed to discuss how to develop policies to support social participation by full-time housewives, from the perspectives of human resource development and utilization. This study focused on three areas of potential human resource development: (a) labor force participation (b) social education (c) volunteerism. It analyzed the related "social infrastructures," especially labor market situation and child care systems. The current governmental policies and other social programs implemented by various institutions as well as the relevant literatures were reviewed. The preliminary policy proposals outlined in this study were evaluated by the policy developers and experts through several hearings and discussions. Programs proposed from this study were as follows : (a) programs to support housewives who wish to find employment or create a self-owned business, (b) educational programs exclusively offered for full time housewives, and (c) programs to award certificates and rewards and to create paid employment tied to volunteer work. In addition, the ways how to ameliorate the gender discrimination by changing the labor and social environments and institutionalizing the child care were discussed.

본 연구는 혁신유형과 네트워크 형태간의 관계를 탐색적으로 고찰하였다. 즉, 기업의 혁신유형에 따라 사회적 자본의 특성이 어떻게 다르게 나타나는지를 실증 분석하고 있다. 이 관계를 검증하기 위해 2005년 6월에서 7월 사이에 실시된 "경북 IT기업 기술혁신활동 조사"에서 나타난 168개 기업 자료를 실증적으로 분석하였다. 분석은 IT기업의 기술혁신 유형변수로 '탐색형 기업', '활용형 기업'으로 구분하였고, 사회적 자본은 네트워크의 형태를 나타내는 '구조적 변수'와 강도를 나타내는 '관계적 변수'로 구분하여 구성형태를 분석하였다. 분석 결과, 탐색형 기업에서는 네트워크의 범위가 넓고(sparse network) 약한 연계(weak tie) 관계를 가지는 반면, 활용형 기업에서는 네트워크가 범위를 좁고(dense network) 강한 연계(strong tie) 관계를 가지는 것으로 나타났다.
