  • 고효율 태양전지를 위한 결정질 태양전지의 구조 중 UNSW에서 개발한 BCSC(buried contact solar cell)가 있는데, 이는 전면 전극을 laser 처리 후 무전해 니켈 도금으로 형성한 것이다. 이같은 전면 전극을 형성하기 위해서는 무전해 nickel 도금 후 열처리가 필수적이다. 우리는 이 공정을 확립하기 위해 결정질 wafer에 후면을 PECVD로 SiNx막을 형성하여 $30\Omega/\square$로 도핑한 후 후면을 불산으로 제거한 상태에서 양면을 니켈 무전해 도금으로 전극을 형성하여 $300^{\circ}C,\;350^{\circ}C,\;400^{\circ}C$에서 각각 3,6,9분간 진행하였다. 그 결과 $400^{\circ}C$에서 3분간 열처리된 sample이 상대적으로 가장 명확한 IV curve를 형성하였다. 이 실험의 결과는 PN 접합 구조에서 전극을 nickel로 사용할 때 유용하게 사용될 수 있다.

  • The defense industry export of Korea has been steadily risen since 2006. It is attained $340million, the highest export amounts ever, in 2013. As the defense industry export increase, Defense Acquisition Program Administration (DAPA) built defense industry export and import management system to assist export and to protect defense technologies. In this paper, we study factors to activate the defense industry export and import management system using Technology Acceptance Model(TAM) in compulsive usage environment. The significance of this study is as follows: First, we prove the reliability and feasibility of measurement variables in defense industry of compulsive usage environment. Second, we suggest factors to activate the defense industry export and import management system. Third, we present methodology to find factors in computation systems of public institute using TAM.

  • We presents a source module implementation system using building blocks as one of the software reusing approach. Based on module text retrieval system, system is composed of library management program and new module making program for module management. We build a software module by virtue of the reuser's customization and by applying a practical module to this model and then proved that program development through reusing approach is better than that of writing out a source code directly.

  • Developing the safety training program has been a major research topic in CBT as well as in traditional teaching and learning. With regard to determining learning control in CBT, it is important to consider not only the characteristics of learning tasks but also student's individual difference. In this regard, the purposes of this study are to develop the CBT program as well as animation program in order to increase the student's performance.

  • In this paper, we introduce IEC 60300(Dependability program management) into urban transit system, and propose effective method to apply IEC 60300 to Subway Corporation. The dependability is the collective term used to describe the availability performance and its influencing factors such as reliability performance, maintainability performance and maintenance support performance. A dependability program covers all phases of a system's life cycle from planning to operation and possibly disposal, and is composed of program elements divided into tasks.

  • Chonnam National University Medical School has designed and implemented two career planning programs: a three-phase curriculum-based program and a longitudinal non-curricular program over the course of 6 academic years. The three phases of the curriculum-based career planning program are self-assessment, career exploration, and field experience. The non-curricular career counseling program operates through a faculty advisor system, with each faculty member guiding a group of students from each academic year, and students in each year forming a mentor-mentee relationship. The non-curricular career exploration program consists of a student research support program, an international practice program in basic and clinical medicine, and a specialty exploration fair. A survey conducted among 38 graduates (54.3%) working as interns at Chonnam National University Hospital revealed that graduates preferred autonomous elective subjects within the curriculum-based program. They also responded positively to the faculty advisor system, through which they maintained close relationships. A focus group interview with three interns indicated that subjects providing direct experience in fields of interest and courses that students could choose freely were helpful in career decisions. Through follow-up research, it is necessary to design and operate a systematic career planning program based on an analysis of the needs of graduates taking part in a residency training program after selecting a medical specialty.
