Human being can be divided into five elements in the Oriental Medicine. The remedy by using five elements constitution has been shown great effects clinically during that time. Therefore, The job design research considering Oriental Human Constitution is needed for job efficiency and safety. In This study, we examine whether the theory can be applied for job design through the experiment by 'Digital-type Speed Anticipation Reaction Tester' and suggest the desirable direction of job design.

Governments seek to advance public industry had planed to decreased by 50% of KORAIL management deficit in 2010, The transition to a profit in 2012. In addition. The government will not achieve the goal by 2010, management announced plans to review the case, and privatization. Office of unprofitable station and vehicle maintenance, maintenance work to make cost savings through outsourcing hed discussed how to create KORAIL advancement. April 2011 the government, "A study on th Efficiency of Conventional Railway Infrastructure Maintenance R&D Report" progresses, conventional railway infrastructure maintenance has focused attention on the field. However, the general maintenance of railway facilities without the knowledge and safety awareness, as compared to foreign railway personnel, and productivity has pointed out the contradiction. Economy and efficiency of the railway in order to pursue a public awareness and safety and professionalism is required. In this study, the conventional railway infrastructure maintenance in accordance with Facts would like to introduce efficiency measures.

In this study, we developed a heuristic algorithm to get better efficiency of clustering than conventional algorithms. Conventional clustering algorithm had lower efficiency of clustering as there were no solid method for selecting initial center of cluster and as they had difficulty in search solution for clustering. EMC(Expanded Moving Center) heuristic algorithm was suggested to clear the problem of low efficiency in clustering. We developed algorithm to select initial center of cluster and search solution systematically in clustering. Experiments of clustering are performed to evaluate performance of EMC heuristic algorithm. Squared-error of EMC heuristic algorithm showed better performance for real case study and improved greatly with increase of cluster number than the other ones.

To keep enterprise's competitiveness on condition of the automatic manufacturing system such as FA, FMS and CIM, all the maintenance problems should be considered seriously in not only production and maintenance but also related industrial safety. As we analyze in the surveys for the maintenance management of domestic enterprises and the causes of Industrial accident, there will be necessity of drawing up countermeasures for prevention of industrial accidents and for ensuring expertise maintenance technologies. Based on these analyses, this study studied the safety information system, maintenance management information system, and the machinery condition diagnosis technique by using of the knowledge-based system under the internet environment. This web based knowledge-based diagnosis system can easily provide not only the knowledge of expert about deterioration phenomenon of industrial robot, but also the knowledge of relating safety and facility on everywhere, everytime. Therefore, when we use this system, it is expected to improve the efficiency of business processes in the production and safety.

To keep an enterprise's competitiveness on the condition of the automatic manufacturing system such as FA, FMS and CIM, all the maintenance problems should be considered seriously In not only in production and maintenance but also in related industrial safety. As we analyze in the surveys the maintenance management of domestic enterprises and the causes of Industrial accident, there will be necessity of drawing up countermeasures for preventing industrial accidents and for ensuring expertise maintenance technologies. Based on these analyses, the safety information system, maintenance management information system, and the machinery condition diagnosis technique are studied by using of the knowledge-based system under the real-time computer-operating environment and using fuzzy linguistic variable. This computer system based knowledge-based diagnosis can easily provide not only the knowledge of expert system about deterioration phenomenon of industrial robots, but also the knowledge of relating safety and facility all the time. Therefore, it is expected to improve the efficiency of business processes in the production and safety when we use this system.

Internal engine is the main power source of vehicle and is the main source of air pollution. To satisfy this getting rigorous emission regulation, it must be solved simultaneously the dilemma of reducing emission gas and increasing heat efficiency. Diesel engine is preferred compare with gasoline engine in aspect of energy consumption but it must be solved reducing the containing of NOx, CO and HC. In this study: 1. Looking for alternative of performance improvement of Exhaust Gas Recirculation(EGR) which is emission gas reduction system. 2. Reducing malfunction of controlling emission gas. 3. Made possible precision control.

Due to the competition between the various professional events, it is imperative for the team's management to improve efficiency by removing the inefficiencies of the professional team in order to gain a competitive edge. This study use different Data Envelopment Analysis (DEA) models to measure the efficiency of professional sport organizations. In this mathematical-analytical study, this study first reviews the related literature to analyze the input/output variables. In the end, the variables were detected and the data for this study were gathered from the Korean Basketball League (KBL). While previous studies examine relative efficiency of Korean Professional baseball teams by using CCR model, this study fully utilize the DEA method to investigate Korean professional sports organizations' operating problem. Thus, this study propose full results of DEA analysis such as efficiency score (overall, technical, and scale efficiency), slacks in inputs and outputs of inefficient organizations, Malmquist index) As a result, this study provides not only the exact productivity information of a team and a way of improving a firm's productivity with a decision maker.

전 세계적으로 수소에너지에 대한 관심이 점차 증가함에 따라 수소 생산, 저장, 운송, 이용 분야에서 응용 기술의 개발이 활발히 진행되고 있다. 국내에서도 울산 수소타운을 조성하여 시범운영 중에 있어 수소에너지 응용처 확대에 대한 가능성을 높이고 있다. 울산 수소타운은 가스 사용 압력에 따라 고압부와 저압부로 구분할 수 있는데 고압부는 '고압가스안전관리법'을 적용하여 안전관리를 하고 있고 저압부는 '수소타운 시범사업의 안전관리에 관한 지침'을 적용하여 운영 중에 있다. 본 논문에서는 울산 수소타운 내 0.1MPa 이하 저압 수소 사용시설의 안전관리 효율성 향상을 위해 저압 수소사용 시설 및 안전관리 항목 분석을 통해 안전관리 방향성을 검토하고 향후 개선 방향을 제시하고자 하였다. 본 연구의 결과를 통해 국내 수소타운 활성화 및 안전 관리 효율성 증대에 도움이 될 수 있을 것으로 기대한다.
