원자력발전소 설계업무 수행중 생산되는 전산데이타를 반영구적으로 보관하기 위하여 Autocom 장비를 이용한 마이크로피쉬(microfiche)를 생산해 왔으나 이 장비의 노후로 인한 잦은 고장 및 데이타의 재사용 불가로 인해 기기의 교체가 요구 되었다. 또한 영광 3호기 이후, 교체노심설계 및 핵연료 설계등의 원전 설계업무에 UNIX Workstation(W/S)이 사용되면서 UNIX 시스템의 네트웍을 이용한 온라인 데이타 저장의 필요성이 대두됨에 따라, 이에 대한 하드웨어 분석과 테스트 과정을 거쳐 분산 운영되는 UNIX 시스템에 적합한 CD-ROM 저장시스템을 구성하였다. 본 논문에서는 이러한 CD-ROM 저장 시스템의 기술적인 내용을 분석하고 향후 보완 및 개발되어야 할 내용을 제시하였다.

In the construction, VR(Virtual Reality) is simply used by users to implement and experience 3D modeling in virtual reality, such as safety, practical education, and promotion. The VR related research includes content development and visualization simulation such as disaster safety evacuation simulation and design education contents. Research on developing suitable VR and presenting directionality is insufficient, which is required in practice. Therefore, in this study, prior to the development of VR suitable for the construction, quantitative evaluation, and analysis based on the judgment of experts are performed. However, the research was conducted on the design stages, which are believed to have high needs and application effects of VR during the lifecycle of construction. There are nine tasks that can be applied to VR in the design stage, and these tasks were evaluated and analyzed using IPA(Importance Performance Analysis) by surveying the level of expectations, importance, and performance. As a result, it was evaluated and analyzed that VR and content development was necessary for the review of member interference and collaboration work for decision making among related stakeholders. The results of this study are expected to be used as basic data for the development of VR to be applied in the design stage to the future.

The purpose of this study is to investigate how the vendor suitability factor affects ERP introduction factors of domestic small and middle businesses and internal performance. When domestic firms introduce an ERP package, they mostly use the package already developed by ERP firms. Therefore, this study tried to analyze that the suitability factor of an ERP package supplier serves as a moderating role for ERP internal performance. The study result showed that the vendor suitability factor played a moderating role for ERP introduction factors and internal performance. In other words, the vendor suitability factor served a moderating role for four factors -CEO support, education/training, users' IT capability, and business standardization /formulation- and internal performance. But, it was analyzed that the vendor suitability factor didn't serve as a moderating role for IT infrastructure and internal performance.

기업 및 공공기관의 클라우드 서비스 도입이 확산되면서 업무 시스템에 대한 보안 요구사항이 변화하고 있다. 기존에는 보호해야 할 정보자산이 물리적으로 외부와 분리된 내부 공간에 집중되었다면 클라우드 환경에서는 자산의 분포 범위가 넓어지면서 내부와 외부의 경계가 모호해진다. 따라서 경계 기반의 전통적인 보안 방식은 클라우드 기반 업무환경에 적합하지 않으며 정보 서비스를 이용하는 전 주기에서 암묵적인 신뢰를 배제하고 지속적으로 검증을 수행하는 제로 트러스트 기반의 업무 시스템 운영이 필요하다. 본 논문에서는 스토리지 클라우드 서비스인 아마존 웹 서비스 S3(Simple Storage Service)에 대하여 제로 트러스트 모델을 설계하고, 직접 서비스를 운영하며 제안된 제로 트러스트 모델의 안전성을 검증한다. 제로 트러스트 모델은 스토리지에 접근하는 사용자에 대한 인증 및 식별 기술, 스토리지 암호화 기술, 암호화 키 관리 기술을 활용하여 설계하였으며 제로 트러스트 기술 적용 시, 스토리지 보안성이 향상되는 것을 실제 서비스 운영을 통한 실험을 통해 확인하였다.

Recently, broadcasting companies have been faced with changes in social environment, particularly, the emergence of new media, including the internet, cable TV and DMB, and in the political environment, such as convergence in broadcasting and communications media. To cope with these changes, broadcasting companies are showing increasing interest in building new broadcasting information systems. This study presents how to develop a web-based broadcasting information system for the small and medium-sized broadcasting company. For developing the system, the study describes system configuration, business function relationship diagrams and business flow diagrams, entity relationship diagrams, major programs, and graphic user interfaces. The newly developed web-based broadcasting information system is expected to increase business productivity to a significant extent through faster decision-making and business execution in and out of the company.

지난 몇 년간 인터넷의 확산과 더불어 기업 환경에는 많은 변화가 있었다. 그 중 하나가 전자적인 형태로 접근할 수 있는 정보 양의 급증이라 할 수 있다. (Martin White, 2000 : 신학철, 2001) E-business 환경에서 이처럼 정보의 양이 급증함에 따라 정보의 효율적인 활용은 기업의 주요 경쟁원천이 되고 있다. 정보의 중요성을 깨달은 기업들은 운영효율성 증가를 위해 백오피스시스템과 프론트오피스시스템 등에 많은 투자를 했다. (안승용, 2001) 하지만 새로운 정보시스템 도입 시 레거시시스템과의 통합을 고려하지 않아 업무효율성 향상을 위한 정보기술이 역으로 업무수행을 저해하는 결과를 초래했다. (Jaydip, 2002) 예컨대 기업의 각 시스템간에 정보의 일관성이 결여되어 있고, 필요한 정보 역시 기업내 여러 시스템에 산재되어 있어 정보의 이용 면에서 효율성이 떨어지는 문제에 직면하게 된 것이다 따라서 기업은 각 시스템에 산재해 있는 정보사용의 효율성을 놀이기 위해 기업 내 다양한 정보시스템간 통합의 필요성을 인식함에 따라 이전까지 분산 환경이던 IT환경이 점차 기업정보포탈(Enterprise Information Portal: EIP)같은 통합 환경으로 바뀌게 되었다. (KRG Report, 2002) EIP는 현재와 E-business를 준비하는 기업에 중요한 관심사항으로 떠오르고 있으며 현재 IBM, MS 같은 글로벌 기업 뿐 아니라 다수의 국내 업체들도 통합 솔루션 시장 진출해 경쟁을 벌이고 있다. 본 논문에서는 EIP의 개념을 살펴보고 기존의 정보시스템과 EIP 관련 연구를 기반으로 새롭게 부상하고 있는 EIP의 성과를 시스템 품질과 정보품질로 측정하여 이들 요인이 EIP사용자의 직무성과에 미치는 영향에 관해 연구하였다. 본 논문은 EIP를 도입한 기업을 대상으로 EIP성과에 대한 연구를 진행하여 EIP를 도입하거나 구현중인 기업에게 적합한 경영관리적 방향을 제시할 수 있을 것이다.

This study was aimed to establish the self-concept as the dental profession and dedicate to the development of dental hygienist role by understanding the relation between the self-concept of dental hygienist and practice performance as dental hygienist. Following the thorough investigation of this correlation, the importance of self-concept as the dental profession was confirmed, and the understanding about the practice performance as dental hygienist was renewed. Dental hygienist working in dental clinic located in Jeonju city, Jeollabuk-Do were selected as the subjects of this study, and the materials were collected from Mar. 11 to Mar. 25, 2002 for 15 days. SPSS was used for analysis of data to deal with ANOVA and verification of Pearson correlation. The results of this research can be summarized as follows; 1. In comparison of the degree of professional self-concept according to the general characteristics of the subjects, there were significant differences in religion(p<.05) and educational background(p<.01). 2. In comparison of the degree of practice performance according to the general characteristics of the subjects, the results showed the significant difference in religion(p<.05). 3. There were highly significant correlation between the professional self-concept and practice performance as dental hygienist(F=.663, p<.001).
