Product Life cycle Management (PLM) is an indispensable tool for manufactures to develop competitive products in an efficient way. This enlarges the number of participants for product development who should understand PLM for their supporting activities. However, burdens for developing example products, maintaining complex PLM systems and training prerequisite skills for engineering tools such as CAD systems prohibit an efficient introductory course to PLM. This paper proposes a comprehensive introductory course to PLM that bases on general product development process. In addition, it enables participants to build their example products with familiar Lego blocks and to construct 3D CAD assembly models by using predefined 3D elements. The PLM system for the course provides an intuitive and simple user environment for participants to specify their parts lists, associated 3D CAD models, and product structure of example products. Experiences on a class of the course show it is a valid and efficient education and training method for the PLM introduction.

Since most human activities in a nuclear power plant are perfirmed in the main control room (MCR), it is important to have its design well human-engineered, both physically and cognitively. Much research efforts have been given for better, operator-centered designs of human-machine interface in MCR capitalizing today's advanced information technology. Korea is among those who are actively expending such research for the next-generation nuclear plants. This paper analyzes two forerunners among the emerging MCR designs, namely Nuplex 80+ and N4, from the perspective of cognitive systems engineering. Since the two show some fundamental differences in their design concepts, the principles with their pros and cons must be enumerated to benefit our own design of new control rooms. This paper also lists many other decision-making points that emerged due to the new availability of cognitively based on cognitive engineering principles. The future scope and directions of related research are suggested.

The purpose of the study is to develop an integrated viewer which can display both text and image files on the Internet environment. Up to now, most viewers for full-text databases can be displayed documents only by image or graphic viewers. The newly developed system can compress document files in commercial word processors (e.g, 한글TM, WordTM, ExceITM, PowerpointTM, HunminJungumTM, ArirangTM, CADTM), as well as conventional TIFF image file in smaller size, which were converted into DVI(DeVice Independent) file format, and display them on computer screen. IDoc Viewer was evaluated to test its performance by user group, consisting of 5 system developers, 5 librarians, and 10 end-users. IDoc Viewer has been proved to be good or excellent at 20 out of 26 check lists.

[Purpose] Recently, skyscrapers have sharply increased throughout the world, including South Korea. Although a skyscraper has its own merit such as the landmark of a city, it also has various problems like massive energy consumption. This study is aimed to establish the concept of environment-friendly skyscraper and propose a plan to realize skyscraper after analyzing the architectural, facility and environmental friendly elements of skyscrapers. [Method] This study lists up skyscrapers over 40 floors and 200 meters high. Upon 10 constructed buildings, it analyzes their basic plans and the green building technologies applied to them and suggests effective and environment-friendly architectural plan. [Result] This study examined the distinctions of the layout, shape, facade, and floor plan plane of 10 skyscrapers and found out specific techniques to be used for the use plan of natural energy, plan for saving resources and reducing wastes and a plan for environmental architecture and system.

In this paper, intelligent marketing and merchandising methods utilizing data mining and Web mining techniques are proposed for online retailers to survive and succeed in gaining competitive advantage in a highly competitive environment. The first part of this paper explains the procedures of one-to-one marketing based on customer relationship management(CRM) techniques and personalized recommendation lists generation. The second part illustrates Web merchandising methods utilizing data mining techniques, such as association and sequential pattern mining. We expect that our Web marketing and merchandising methods will both provide a currently operating Internet shopping mall with more selling opportunities and give more useful product information to customers.

This paper develops a portfolio management game applicable to Korean Stock Market with an emphasis on teaching and training aid. It allows each participant to start out with a certain amount of money and pick his favorable stocks from a list of stocks chosen by instructor. Each participant must make a transaction at each time period and he gets a readout that states his individual performance, i.e., stock lists, cash on hand, net worth, transactions he has made and rank in accordance with his net worth. This game package consists of 10 subprograms and 7 files written with Fortran language for use on the Nova 840 computer and is divided into 3 main categories according to their functions, i.e., book-keeping function, data processing function and information searching function. This package may be used for training portfolio decison makings in the stock market and for comparing various investment methods through hypothetical investments.

CORBA가 명세하는 객체참조 메커니즘인 이름 서비스와 트레이딩 서비스만으로는 MICS시스템이 요구하는 다양한 기능을 수용할 수 없으므로 추가적인 객체관리자의 구현이 필요하다 따라서 본 논문에서는 MICS 시스템에서 영상처리 객체의 부하와 결함과 관련된 실시간 정보를 이용한 부하분배와 결함허용을 제공하는 객체 참조서비스를 제공하며, 영상처리 객체의 관리와 사용자환경의 동적 구성을 지원할 수 있는 객체 관리자를 설계, 구현하였다. 제안된 객체관리자는 이질의 분산 환경에서 MICS시스템의 신뢰성과 확장성을 제공하여 클라이언트와 서버간의 고품질의 서비스를 제공한다.

A standardized ergonomics kit is suggested to evaluate and reduce musculoskeletal hazards that yield large socioeconomic burdens in the work system. This kit comprises basic and detailed analysis tools with proper tool selection rules. The basic tool includes a checklist for various risk factors to screen potentially hazardous jobs among manual works. Selective detailed analysis tools can then be applied to the screened job lists for more quantitative and precise evaluation. The tool selection rules are devised for using the basic and detailed analysis tools in a mutually supplemental way. To validate the standardized ergonomics kit, it was applied to evaluate jobs related to the musculoskeletal hazards in a paper-making industry. Among 101 manual jobs investigated, 44 potential hazardous jobs were screened during basic investigation phase and finally 16 hazardous jobs were identified by the detailed analysis phase. The result provided fairly promising ideas of ergonomic interventions for the hazardous jobs.

As a recent global trend, the majority of plant projects are delivered through EPC or EPC-turnkey contracts, where a contractor's liability is more complicated because of the mega size scale and financing method. Previous researches have been lacking a practical usability for project members for liabilities of contracts. Those were focused on solving the claims or schedule calculation issues only. The objective of the present study was to develop a validation process for LDs (liquidated damages) in contractor's liabilities with various case studies and expert judgments. As summarized in this paper, the processes and tools were developed with project life cycle process. The project preparation phase includes 3 step check lists to determine the Go or No-go for projects. In progress phase, contractors should focus on the response strategies for claims with liabilities. The study concludes that those developed processes and tools will help to manage risk of LDs for the contractors in the overseas projects.

최근 병원정보시스템은 병원 경영을 위한 다양한 서비스, 진료 활성화와 진료의 질 향상을 위하여 대용량의 데이터베이스를 보유하게 되었다. 하지만, 병원정보시스템에 대한 정보보호대책은 미흡한 편이다. 따라서, 병원정보시스템 구축할 때, 정보보호에 대한 대책을 적절하게 마련하여 정보보호 감리를 수행하여야 하며, 위험관리를 통한 정보보호 수준을 유지할 수 있도록 정보보호 관리체계(ISMS)를 수립하고 관리해야 한다. 본 논문에서는 병원정보시스템, 정보보호관리체계, 병원정보 보호 요구사항 및 위협요소를 근거로 병원정보시스템에 적합한 정보보호 감리모형을 제안하였다. 감리모형에서는 의료기관의 특성이 잘 반영되어 있는 ISO27799와 비교하여 점검항목들을 도출하였다. 보안영역은 물리적, 기술적, 관리적 영역으로 분류하고 각각에 세부적으로 정보보호 항목들을 도출하였다. 또한 ISO27799의 위험관리 절차에 따라 점검항목을 매핑함으로써 보안성과 효율성을 동시에 향상시킬 수 있도록 설계하였다. 제안한 감리모형은 IT 전문가들의 5점 척도 설문 조사 결과 평균 4.91점으로 나타나 적합하다는 결론이 도출되었다.
