In this paper, we report a case study of applying puzzle solving as a programming practice. There are many students, who have attended computer programming language courses, have had difficulties in accomplishing the course assignments. It is because just following and citing the programming language course materials is not sufficient for constructing computer programs. Many professional developers have stated that computer programming for small problems is an art of puzzle solving, where developing enterprise-size computer programming projects involves architectural insights which are already dealt in software engineering literatures. Following those backgrounds, we have explored the applicability of puzzle solving in a C++ object oriented programming course and have reported the results. The experimental results show that puzzle solving is effective to the students who are interested in computer programming and have at least beginner-level knowledge and expertise, but it turned out that puzzle solving assignments still does not draw much attention of the students who are not seriously interested in computer programming.

Spatial calibrations have been performed on the Medium-sized Aperture Camera (MAC) of the RazakSAT satellite. Topics discussed in this paper include the measurements of system modulation transfer function (MTF), relative pixel line-of-sight (LOS), and end-to-end imaging tests. The MTF measurements were made by capturing the scanned knife-edge image on a pixel, and an issue in the MTF calculation algorithm is discussed. The method used to place the focal plane at the correct focal position is described, since they make use of MTF measurements. Relative LOS measurements are done by theodolite measurements of the telescope. Qualitative ground test result of end-to-end imaging is given.

Government-driven informatization support projects for small and medium companies turn into collaborative information technology alliances between mother companies and their suppliers. These collaboration efforts are driven by a mother company that can influence and support its suppliers. A mother company establishes a proprietary evaluation system for suppliers' informatization level and enforces the suppliers to use their ERP (Enterprise Resource Planning) systems above a certain level. This paper presents a Samsung Electronics case to find determinant factors for ERP system usage level. This case study aims at providing long-term strategies for the collaboration project and helping the suppliers effectively pursue their informatization projects. Furthermore, the case study will reveal issues and tasks for the mother companies to accomplish sustainable success for their suppliers' informatization.

Single PPM Quality Innovation Program is to pursuit of defects below 10ppm in outgoing quality for strengthen the small and medium enterprise's competitiveness. This study aims to find that whether quality innovation promotion is significant or not in the ISO 9001 certification enterprises. To perform this research, we surveyed CEOs, managers and workers working for manufacturing business, we distributed 250 sheets totally and withdrew 171 sheets. We analyzed 135 sheets that we could use for this research using SPSS 15.0 and AMOS 18.0 program.

This study deals with the improvement of production process on a flow production system with the consideration of six sigma. We analyze the production process and survey the important factors of improvement of productivity. Using a six sigma, we find strategic point and suggest a reformation of production process. We applied a simulation technique to simulate the production line proposed by the result of the Six sigma. With the result of the simulation, this study analyzes the propriety of production line and proposes the alternatives of new production process.

본 연구는 거시경제학의 기초이론인 케인즈 모형을 사용하여 지역의 대학이 지역 경제에서 차지하는 역할이 어느 정도가 되는지 계량적 분석과 설문지를 통한 실증분석을 하였다. 먼저 케인즈의 모형을 사용한 분석결과, D 대학 학생들은 1994 년$\sim$2002 년까지 연간 1 천억 이상 소득 창출효과를 보였다. 이것은 속초시 총소득의 $15%{\sim}30%$ 이상을 차지하는 상당한 비중이라 할 수 있다. 두 번째 분석으로는 D 대학 학생과 지역주민을 대상으로 한 설문 조사를 하였다. 특히 같은 도내 대학교인 K 대를 대상으로 조정 권 (2002)의 연구와 그 결과를 비교하였다. 분석결과 D 대학과 K 대는 전반적으로 유사한 결과를 보였지만, 지역주민들은 실제 계량적 분석결과와 달리 지역대학의 경제적 영향력을 과소 평가하는 것으로 나타났다. 이러한 지역주민 (지방자치단체) 의 지역대학에 대한 인식의 차이와 이해 부족은 지역대학의 잠재능력을 사장시킬 뿐만 아니라 결국 지역발전의 저해 요인으로 작용한다는 것을 시사하고 있다.

한국기계연구원 기계.재료기술정보센터는 경남지역 6천여 제조업 중심 기업들의 인터넷마인드 확산.CALS적용.인터넷정보검색.EC호스팅 등의 업무를 추진해 오면서 얻은 노-하우를 바탕으로, 중소업체들의 정보화 현실을 감안하여 기업(특히 중소기업)이 가장 필요로 하는 EC분야를 적용하기 위해 노력하고 있다. 기업간 EC는 종래에는 VAN을 통한 EDI가 주를 이루었으나, 인터넷이 활성화되고 이용자 수가 폭증함에 따라 거래처 개척, 물류, 결제 등 광범위한 거래 활동은 사이버화해 나가는 것을 대상으로 하고 있으며, 기존 EDI와는 달리 지속적인 거래 관계만을 전제로 하지 않고 거래 활동의 다각화를 시도하고 있다. 이러한 취지에 근거하여, 본 논문에서는 기업간(또는 사업자간) 전자상거래의 유형 중 제품을 생산하는 기업을 대상으로 불특정 다수기업이 인터넷들 통해 제품을 홍보하고 제품 수.발주가 성사되도록 지원하는 유사제품 검색 기능을 탑재한 제품을 형태의 인터넷 마케팅 서버(가칭 비즈니스 서버)를 제안한다.

With Zohar(1980)'s research on safety climate and industrial safety, occupational safety and health literatures begin to emphasize the influence of organizational context. Based on this research trend, this paper tried to review the relationship between safety efforts and employee safety participation, and the moderating effect of safety motivation on such relationship. Based on the responses from 643 manufacturing workers, the results of statistical analysis showed that company precaution activity and management safety involvement have affirmative effects on the employee safety participation, but safety education has not. The extent precaution activity forces on participation activity was proved to be influenced by employee safety motivation.
