Electrical product safety certification is for public safety. Korea electrical safety certification (KC) is being tested and certified on the base of Korean electrical appliance safety act and KC scheme. There are operating system and Electrical safety standards in the KC scheme. KC' operating system was adapted from japan operating system of Japan certification scheme. But KC certification' electrical safety standard was adapted from IEC standards of IECEE CB scheme. So There are many problems such as difference of version between KC standards and IEC standards, discrepancy between operating system and standards. Therefore, This paper analyzed the reason of discrepancy and proposed the improved KC certification operating system in order to reduce cost and to save time in the procedure of issuing KC approval for public safety in using electrical products and also for global competence.

The objective of this was to improve a transportation cost relation between Central Distribution Centers(CDCs) and Regional Distribution Centers(RDCs), to control inventory cost concerning safety stock for each service level, by reviewing distribution steps connecting CDCs and RDCs under the price discount. It was also to examine and compare operating costs for the following two alternative suggestions for setting the service standard as a counter measure for a stock-out of the distribution network system management. First, provision by dispersing the safety stock to the CDCs and RDCs; and second, exclusive provision of the safety stock only to the RDCs. The cost comparison analysis was made for each category of purchase costs, regular transportation costs, express transportation costs, and inventory holding costs.

Domestic as well as global automobile manufacturers are making greater efforts in cost reduction to strengthen the competitiveness. In this study, we developed a program to effectively manage standard time of automobile assembly line, and confirm based on A-automobile factory data. For the purpose, we develop the system which is possible to manage standard time as well as calculate man-hour for automobile assembly line.

Price quotations for SOR / RFQ from OEM clients is a very important process in the automotive parts industry. However, OEM clients are demanding a price quote on short duration but it takes long delivery time due to sales, research and development, purchasing, production and cost management departments role and jobs focused on detail and responsibility. And to provide a reasonable alternative with eliminating the waste of non-value processes is to achieve OEM clients satisfaction through standardized and parallel processing, IT system based on the systems and processes of global benchmark companies.

화학사고의 예방 및 대응을 위한 화학물질관리법이 2015년 전부 개정되었다. 이를 계기로 유해화학물질 취급시설의 설치 및 관리기준도 상당히 강화되었다. 하지만, 일부 기존시설의 경우 시설기준 준수가 어려운 쉽지 않은 경우가 발생하지만 일괄적으로 적용되고 있어 산업계에서는 어려움을 호소하고 있는 실정이다. 본 연구에서는 이러한 최근 2년(2017-2018)간 취급시설 중 민원(1,087건)이 가장 많았던(2017:117건, 2018:83건) 방류벽에 대한 선행연구, Flacs 시뮬레이션, 국내·외 기준, 만족도 조사 등을 통해 보다 합리적인 방안을 마련하고자 하였다. 이에 현재 가동 중인 기존시설에 한하여 방류벽의 설치 목적을 고려하여 화학물질 유·누출을 신속하게 감지할 수 있고 신뢰성을 높이기 위해 감지기를 추가로 설치하거나 상시 모니터링이 가능한 폐쇄회로텔레비전(CCTV)을 추가로 설치·운영하는 경우 추가 대체방안으로 인정하였다. 이는 부지를 확보하기 힘들거나, 공사비용 등 경제적인 문제로 법적인 규제를 이행하지 못하는 영세사업장 또는 중소기업의 안전측면과 비용적인 측면에 도움이 될 것이다.

연구목적: 기존의 인력에 의한 안전점검은 기술자의 안전이 우려되거나 접근이 어려워, 평가 및 데이터 확보에 한계가 있었고, 시설물의 노후화로 유지관리 대상이 증가함에 따라 더욱더 큰 문제가 되고 있다. 드론 기술이 발전하면서 외관조사에 이를 활용할 경우, 인력의 안전 보장, 시각적 데이터 확보, 신속한 점검 진단이 가능하며, 최근 드론에 의한 시설물 안전점검이 일부 도입되는 등 활용도가 높아지고 있다. 활용성을 보다 강화하기 위해서는 드론에 의한 시설물 외관조사의 대가기준이 필요하다고 판단되며, 본 논문에서는 댐을 대상으로 연구를 수행하였다. 연구방법:품셈 산출을 위해 기존 국내 안전점검 및 드론관련 대가기준을 조사하고, 드론을 활용한 안전점검 관련 절차를 비교분석하여 작업 절차 및 공종에 대하여 검토하였다. 또한 실제 댐에 대한 드론 촬영 및 입면정사영상 제작을 통해 실증 자료를 수집하였다. 연구결과: 드론을 활용한 시설물 안전점검을 위한 작업공종을 도출하였고, 작업공종에 따라 두 개의 댐을 대상으로 실증조사결과를 수집하였으며, 이를 바탕으로 댐기준시설물 규격 기준으로 품셈 안을 도출하였다. 시설물의 구조형식별, 규격별 조정비는 기존 지침을 적용하고, 기상기준점측량이 필요한 경우 건설공사표준품셈의 무인비행장치측량의 품을 적용하도록 하였다. 결론:드론을 활용한 외관조사 시 GSD를 세밀하게 할수록 촬영 사진 수가 크게 증가하여, 대가기준을 산출을 위한 보정으로 조정비 개념을 적용하였다. 더불어 안전거리 유지를 위해서는 최대 GSD가 한계를 나타내는 문제점도 고려해야 함을 알 수 있었다.

This research analyzes clean room major fire prevention standard of clean Room (FM, IRI, and NFPA Code), the structure of Performance-Based Fire Safety Design (PBD) applied the korean fire industry situation. Performance-Based Fire Safety can operate effectively the performance of fire protection equipment & building design, so the fitness of fire safety system can be embodied by operating this. moreover, cost to be consume fire safety of real building can reduce and Performance-Based Fire Safety is considered to important technique in fire protection field. A fire in a clean room may cause a serious loss by spreading smoke particles. We will be investigated by using a computational fluid dynamics, for loss prevention by smoke spreading from one fire area to another for clean room and compared the Performance-Based Fire Safety Design with the prescriptive code design. The methodology of fire safety performance-based fire safety design and guarantee of many kinds design skill of fire system and developing design procedure will be very serious one in order to improve efficiency of domestic system. Therefore, This research will be contributing to secure safety of clean room and to set up the performance-based fire safety design in Korea by regulation for the performance-based fire safety design effectively.

To develope a domestic machinery industry, international competition through reducing cost by increasing productivity is as important as evolving technology and increasing quality. In this study, we have studied in application of GT technology. GT is a skill that acquires high productivity using part's resemblance for multi part and small size production like mass production. We have classified group, such as design, layout and the others, to be applied systematically. The design group includes retrieval for drawings and study for GT design. The layout group includes GT layout, analysis of production process and study for composition method. And others include scheduling, standardization and standard process.

This study is to investigate and compare domestic hazardous toys with harmful substances with foreign toys so that we can find out management criteria for in cognitive infants. Actually, commercially used toys have been collected and tested to find out more effective management standard. it is tried to produce evaluation criteria of environmentally harmful substance but variety of product is needed for overcoming actual barrier due to lot of difficulty huge cost, time, objectiveness. Therefore, This study does not cover all the above. Establishment of evaluation criteria for product harmfulness made by Government or Local government should be continued to improve. Foreign reference material for toy product in Europe, USA, Japan have been investigated and domestic product have been collected and tested for containing heavy metals, formaldehyde, phthalate in the study. All the test have been made in accordance with KSM ISO 2124 to measure heavy metal transfer into body. Toy product used for the study have been purchased in the real market and some of them contains harmful elements with over standard. Post management system such as RAPEX to control periodically should be established for plastic toy with low quality product.
