There are something unreasonable, unsatisfactory on the law system for laboratorial safety enforced by the government from April 2006. Therefore, the system should be reviewed and revised to be satisfactory for current research condition. This study is to analyze research areas for improving laboratorial safety and to show safer ideas. With more detail, more practically improving ideas have been shown for systemizing safety assessment in advance, effective organization of laboratory, safety committee and their regulation. It is expected that better safety level all the concerned engagement, reasonable revision of safety regulation of laboratory, can be made by this research result.

정부조직에서는 성과관리제도의 법제화 이후 중앙부처에서부터 지방자치단체에 이르기까지 광범위하게 확산되어 가고 있다. 성과관리제도가 지방자치단체에서 성공적으로 정착하기위해서는 구성원들의 수용성을 제고하는 것이 선행되어야 한다. 따라서 본 연구에서는 지방자치단체의 성과관리제도의 수용성에 영향을 미치는 요인을 확인하고 정책대안을 모색하고자 하였다. 연구결과 수용성제고를 위해서는 공정한 제도의 마련과 충분한 제도에 대한 공감대 형성이 선행되어야 하며, 제도에 대한 인식개선을 위해 체계적인 교육프로그램의 시행과 의견수렴장치의 마련이 요구된다. 또한 조직에 적합한 평가체계를 수립하고 객관적인 지표도출을 위한 매뉴얼 개발 등의 적극적인 노력이 필요하다. 마지막으로 제도의 연속성을 보장하고 비전중심의 성과관리제도로 변화하는 것 또한 수용성을 제고하는 중요한 요인이다.

Molecular characteristics and improving methods for thermal stability of enzyme have been considered. Intrinsic and extrinsic stabilizing mechanisms are two governing principles for enhanced thermal stability of enzyme in molecular basis. Factors contributing to the former and the latter mechanisms may be involved in the enhanced thermal stability of enzyme complementarily. Also, the methods for improving thermal stability of enzyme which comprise reaction in organic solvent system, chemical modification, immobilization, sequential unfolding and refolding, gene manipulation techniques and enzyme-antibody complexing are reviewed.

Purpose This paper attempts to identify items for improving the usage of PLM(Product Lifecycle Management) systems and suggests ways to prioritize improvement items on the basis of importance. It also tries to find out differences in the importance of improvement items due to the company size, the industry, the job, or the PLM solution. Design/methodology/approach Through a survey from participants to a PLM System Conference, data were collected from a sample of 181 users who had the previous experience in using a PLM system. In order to figure out the differences in the importance among user groups, the F-test with the Scheffe test as a post-hoc analysis was used in case of equal variances and the Welch test with the Dunnett T3 test was used in case of unequal variances. Findings This study sorted out 25 improvement ideas according to their importance assessed by the PLM system users. The top five ideas are improving data consistency, error minimization, fast system response time, enhancing user recognition, and business process improvement. The support group puts higher importance than the general user group in data consistency, fast system response time, enhancing user recognition, business process improvement, dedicated team for data consistency, continuous support from management, hardware performance upgrade, output linkage to other systems, and shortening problem solving duration. The largest company group attaches significantly higher weights than the smallest company group to data consistency, error minimization, fast system response time, business process improvement, dedicated team for data consistency, security with proper access management, output linkage to other systems, and better user interface.

Improving energy efficiency is the important thing of energy saving strategies that was shown up result of IEA meeting and the G8 Summit. Energy audit was started in 2006 that Korea government policy for improving energy efficiency. Who used over 2,000toe/yr(tons of oil equivalent per year) energy consumption has to perform energy audit program of obligation every five years with auditing company. HANMI C&E as a company authorized by Government has diagnosed various type building. This case studies are chosen to best practices by KEMCO. This studies present efficient recommendation methods for improving system performance.

A improving sensorless compensator for the IPMSM(Interior Permanent Magnet Synchronous Motor) drive system is proposed. Generally, the motor drive system is required the robust parameter variation and disturbance. The speed estimation methods of the conventional IRP(Instantaneous Reactive Power) compensator is improved by the speed estimation techniques of the current model observer with the proposed instantaneous reactive power compensator. Performance evaluations of the novel speed error compensator and sensorless control system are carried out by the experiments.

This paper provides an analysis of the effect of input signals, such as acceleration power and generator shaft speed for improving Power System Stabilizer(PSS) efficiency. We consider a single machine and infinite bus system which is modeled by PSCAD/EMTDC. We choose an optimum stabilizer gain with respect to eigenvalue analysis and transient stability analysis to each input signal.

The crystalline silicon solar cell was one of the first to be developed and it is still the most widely used type. The photovoltaic cells will exhibit long-term degradation if the temperature exceed a certain limit. The purpose of this study is to investigate the possible of improving the performance of a photovoltaic cooling system. According to the results of the experiment, the thermal degradation of 44.63degrees was observed by cooling on the surface of photovoltaic cells. It is a decrease of 22.215percent of generating power. It is shown that photovoltaic cooling system is effected on improving the effectiveness of a photovoltaic out of power.

This study is a discussion of business process reengineering for the next generation information system. To be concrete, we analyze and reengineer the current business process in administration of academic, general and research. This reengineering is conformed by 5 steps, as analyzing environmental status that figures out factors of inside or outside (environmental analyzing), analyzing current condition that diagnoses AS-IS process (current situation analysis), establishing information-oriented vision with strategic accomplishing goals accordingly (visioning), deducing detailed improving tasks (defining tasks), and engineering TO-BE process comprehending improving matters (engineering model). This paper shows BPR model for next generation information system.
