  • Yet objective of this paper to spell out in detail the relationship between factors design techniques of data analysis and the design of simulation model of the management organization. Yet an organization is more than a collection of individuals. It is something more than the sum of its Parts: it exists as an entity with its own definable objectives. The management process comprise those activities or functions that managers must perform to effectively carry out this asizned role. However, now that O.R. and system approach has been generalized and the assembly system of hard ware or soft ware through computerization is being improved, the systematization of scientific organization is urgently needed. This paper is to set forth :he problem and solution which are most fit for the management organization in relation to computer. Procedure developed are : 1. Interpretation of the management organization. 2. Design of the computer simulation. 3. Application.

  • Evolutionary operation is a useful tool for improving full-scale manufacturing process by systematically changing the levels of the process variables without jeopardizing the product. This paper presents a system design for the evolutionary operation software called 'evolutionary optimizer'. Evolutionary optimizer consists of four modules: factorial design, many variables, mixture, and mean/dispersion. Context diagram, data flow diagram and entity-relationship modelling are used to systematically design the evolutionary optimizer system.

  • Plant life cycle consists of design, construction, certification, operation, and maintenance phases, and various and enormous plant life cycle data is involved in each phase. Plant life cycle data should be linked with each other based on its proper relationships, so that plant operators can access necessary plant data during their regular operations and maintenance works. Currently, the relationships of plant life cycle data may not be defined explicitly, or they are scattered over several plant information systems. This paper proposes high level design of a plant life cycle data management system based on pre-defined plant life cycle database design. ISO-15926 standard is adapted for the database design. User-interface designs of the plant life cycle data management system are explained based on analysis of plant owners' requirements. A conceptual design of the database is also described with the entity-relationship diagram.

  • 이 연구는 IFLA에서 연구되고 있는 '전거데이터의 기능상의 요건'(FRAD)을 FRAR에서의 변화 양상을 중심으로 명확히 이해하기 위한 것이다. 또한 FRAD가 RDA와 MARC21에 끼친 영향을 분석함으로 FRAD와 관련 규칙과의 관계를 정립하였고, 전거제어를 위한 IFLA의 활동에 비추어 국내 전거제어 관련 목록 규칙과 포맷, 주요 전거DB구축 현황을 검토하였다. 이런 분석을 토대로 국내 전거제어 표준을 위한 고려사항으로 접근점제어방식, 적용범위 확대, 개체-관계 모형과 같은 새로운 접근방식의 도입, 국가서지작성기관의 역할 강화 등을 살펴보았다. 이 연구결과는 전거제어를 위한 기초자료로 활용될 수 있을 것이다.

  • 이 연구의 주된 목적은 한국인의 자기 인식에 나타난 토착문화심리를 탐구하는데 있다. 이를 위해 크게 네 측면, 즉 개인으로서의 자기 인식(보통 때의 나, 독특한 개인으로서의 나, 혼자 있을 때의 나), 가족과 함께 있을 때 자기 인식(아버지, 어머니, 자녀, 배우자와 함께 있을 때의 나), 주위사람과 함께 있을 때 자기 인식(친한 친구, 선생님, 직장 상사, 부하 직원과 함께 있을 때의 나), 타인과 함께 있을 때의 자기 인식(낯선 사람, 외국인과 함께 있을 때의 나)을 분석하였다. 분석대상은 1,465명(초 중 고 대학생 623명, 성인 842명)이었으며, 연구자에 의해 제작된 자유반응형 질문지를 사용하였다. 분석 결과, 한국인의 자기 인식에 나타난 토착심리로서 두 가지 측면이 부각되었다. 첫째는 자기에 대한 인식에서 관계 내 역할의 중요성이었으며, 둘째는 관계 맥락 속에서 유동성있게 변하는 자기의 특징이었다. 이를 토대로 개별적 자기와 관계적 자기의 차원 및 자기의 일관성과 유동성 차원에 대해 논의하였다.

  • The socket-spigot template supporting system is widely used in engineering applications in China. As a newer type of support structure, there has been growing research interest in its bearing capacity. In this paper, four vertical bearing capacity tests were carried out on the basic mechanical unit frame of a socket-spigot template supporting system. The first goal was to explore the influence of the node semi-rigid degree and the longitudinal spacing of the upright tube on the vertical bearing capacity. The second objective was to analyze the displacement trend and the failure mode during the loading process. This paper presents numerical analysis of the vertical bearing capacity of the unit frames using the finite element software ANSYS. It revealed the relationship between the node semi-rigid degree and the vertical bearing capacity, that the two-linear reinforcement model of elastic-plastic material can be used to analyze the socket-spigot template supporting system, and, through node entity model analysis, that the load transfer direction greatly influences the node bearing area. Finally, this paper indicates the results of on-site application performance experiments, shows that the supporting system has adequate bearing capacity and stability, and comments on the common work performance of a socket and fastener scaffold.

  • Since the recently established obligation to implement safety and health measures for specialized workers as outlined in the Occupational Safety and Health Act (OSHA) for nine occupations in January 2020 and five occupations in November 2021, there is a need to verify and inspect the on-site operation of related systems. After a comprehensive fact-finding survey and risk factor analysis, it is necessary to examine the responsibility for on-site safety and preventive measures, along with the roles and responsibilities of specialized workers. Stakeholder analysis is essential to identify the fundamental problems related to the responsibility stipulated in the purpose of OSHA and to explore the entity responsible for implementing safety measures. Therefore, in this paper, we discuss the topic of implementation based on legal standards for on-site safety and preventive measures. Additionally, we develop a role model for appropriate safety measures, outlining the dynamic relationship between those who provide labor and those who provide labor in the context of specialized workers.

  • Studies on the calculation of accident costs include the approach on calculating damage costs covering all accidents regardless of first or secondary party and the one calculating damage costs generated by a single victim. These two approaches have a limitation of considering a subject for costs analysis as a single entity. In addition, research on estimating the interaction effects caused in the relationship between diverse traffic accident features and factors remains inadequate since most studies focused on calculating costs incurred in a single entity such as a victim, damaged building, or social organization in charge of managing car accident. This study intends to identify the expected range of old age where a specific interaction effect would remain, compare accidents between old age section and the entire age section, and discover an exogenous variable to be applied in accident drop effects in senior people and reduced benefits by calculating and testing additional accident costs in case the first party and the second party all pertain to the senior age section. By classifying the entire accidents caused by old drivers according to the types of cars, significant coefficients representing the influence that affects car accidents according to the characteristics are calculated and set them as the representative variables by selecting top variable in accordance with from low to high order. Furthermore, characteristics on five age groups such as a group of over 65 and less than 70, a group of over 70 and less than 75, a group of over 75 and less than 80, a group of over 80 and less than 85, and a group of over 85 are elicited and compared them with these preselected accident characteristics variables, thereby identifying what changing effects come out.
