Household electrical appliances should be designed to satisfy safety standards. An expert system is implemented to support the design process. The general-purpose expert system shell. ART-IM which is running under MS-DOS environment, is used to construct the knowledge-base. A set of rules has been extracted from the EN 60 335-1 that is British standard specification for the safety of household and similar electrical appliances. The main focus of this paper is on codes that have systematic and mormative structures. The internal structure of the safety standard is analysed to improve the process of rule extraction.

기후변화로 인하여 연최대 극치강우의 빈도와 크기가 변하고 있으며 이로 인하여 수공구조물의 안전대책에 대한 문제가 대두 시 되고 있다. 이 때문에 기후변화의 영향을 고려하기 위하여 다양한 방법이 시도되고 있으나 제공되는 전지구 자료가 시공간에서 한계점을 가지고 있어서 이를 단계적으로 극복하기 위한 전체적인 프로세스에 대한 재설정이 필요한 실정이다. 본 연구에서는 전지구격자 일강우자료에서 시작하여 중소규모유역에 적용가능하도록 지점 시간자료로 세분화 시키는 전체적인 프로세스를 소개하고자 한다. 생산된 시간상세화자료를 바탕으로 IDF를 유도하는 과정까지 확인할 수 있으며 이를 바탕으로 기후변화를 고려한 수공구조물의 설계를 재산정이 가능할 것으로 판단된다.

How do we create a next generation Records Management System? Under a rapidly changing system development environment, the records management system of public institutions has remained stable for the past 10 years. For this reason, it seems to be the key cause of the structural problem of the Records Management System, which makes it difficult to accommodate user requirements and apply a new recording technology. The purpose of this study is to present a redesigned model for a next-generation records management system by analyzing the status of the electronic records management. This study analyzed "A Study on the Redesign of the Next-Generation Electronic Records Management Process," records management technology of advanced records management system, and a case of an overseas system. Based on the analysis results, the improvement direction of the records management system was analyzed from several aspects: functional, software design, and software distribution. This study thus suggests that the creation of a microservice architecture-based (MSA) and an open source software-oriented (OSS) records management system should be the focus of next-generation record management.

Europe, the US and Japan have acquired test results on impact coefficient for a long time and applied it to equipment design to secure safety of structures. However, Korean enterprises use the impact factor held by advanced business to design equipment as it is difficult for them to obtain it through tests. In this paper, NX/NASTRAN, was used to perform static load analysis and impact load analysis of a PCB Handler, semiconductor test equipment, and the result was employed to study how to calculate the impact coefficient with the finite element analysis. The calculation method was applied to the JIS(Japanese Industrial Standard), and the impact coefficient of the PCB handler was calculated as 1.27 for the sudden start or stop. The impact coefficient generated by the analysis is expected to make a great contribution to the industry as it can be used to improve the equipment structure and develop on existing equipment in the future.
