This study has been carried out to provide data for the workforce by analyzing personnel status of medical device manufacturers, level of difficulty in securing human resource, reason for difficulty in securing human resource, resignation rate, and recruitment methods. Results, medical device manufacturers are required overseas sales personnel responsible for international certification and exported, regardless of the production item. And the company is located in the metropolitan area did not facilitate a secure workforce. Medical device manufacturers have difficulties in securing personnel, regardless of the employees and sales. In particular, Class 3 production company was more difficult. The reason that it is difficult to secure the human resources is attributable to the poor working conditions of the private companies and there is a few possible employees equipped with the job competency demanded by corporate entities. With respect to the analysis on the retirement rate, the larger the company scale and the more the employee number, more difficulty is experienced in the human resource management. Therefore, for any medical device manufacturers with large organization scale, it would be critical to introduce appropriate human resource management program.

The university admission system for talented students in computer and information areas has been mainly implemented during early admission period centering on universities located in metropolitan area since 1997. However, the current trend is that total number of selected students and universities that are selecting are continuously declining and 14 students were selected from 2 universities in school year 2013. Accordingly, it is difficult to expect positive effects on education related to information on secondary school curriculum, as well as train and select very talented students in certain areas. Such phenomenon is a result of insufficient educational activities on information of secondary school curriculum, as well as a reflection of social perception in the areas of computer and information. It shows that major variable with significant effects of university admission system has not been properly considered in the policy of training talented students at national level and the administration of secondary school curriculum on computer and information areas. Accordingly, there is a need for a comprehensive approach that considers the method and standards of universities' student selection system when establishing related future policy.

The pre-service teachers who did not have basic understanding of SW education and basic knowledge about scratch program which is an EPL tool for research. Therefore, we had time to learn the basic education of SW education and the basic functions of the scratch program over 18 periods before the pre-test of creativity. After conducting pre-test of creativity and conducting SW education applying design thinking over 21 hours, we conducted post-test of creativity. As a creativity test tool, TTCT pattern test forms A and B of Torrance were used. As a result of the verification, it was found that SW education applying design thinking was effective in improving creativity of elementary school pre-service teachers.

The citation & reference writing is a necessary curricular course for undergraduate students to improve paper writing and information literacy. And academic libraries have been involved in relation to the course. In this context, this study examined and analyzed present conditions and contents of the citation & reference writing presently taught by academic libraries. The investigation shows that 9 out of 51 universities in Seoul & Gyeonggi-Do taught the course of citation & reference writing. The course was all taught under the title of 'paper writing' except one academic library, and the librarian taught this course on off-line. Some academic libraries taught only part of citation & reference works while many never taught them at all. Especially, the definition and types of plagiarism and reference works on Website were not appropriately covered.

Jini architecture's Network Plug and Work provides simple and flexible network environment for distributed applications. Through the Jini technology, facilities for dynamically registering and locating mobile agent services can be easily supported, as well as the services useful for activities of mobile agents can be dynamically supported. In this paper, we describe a Jini-based mobile agent system named JMoblet, which provides the basic functions of a mobile agent system such as creation, control, transfer, location and communication among agents. To increase the reliability of the system, it also provides exception handling and persistence of the mobile agent systems for reliability.
