The concept of DSS has been applied to profit organizations however, the purpose of this paper is to show how the DSS helps the school administrators to increase the productivity of their operation. DSS may change the structure and atmosphere of the school, but can't always make success in its implementation. Therefore top management should know the problems and its major limitations. Recently the price of micro computer has become cheaper and its capabilities has improved a lot. We'd better notice that decentralized control system will take place in school in the future.

우리 나라 5대 재벌그룹 기업들의 노동자 경영의사결정 참가의 실정을 단체협약과 노사협의회 규정들을 중심으로 살펴본 결과 다음의 결론들을 얻었다. 첫째, 분석대상 기업들은 장기전략 수준 및 작업현장 수준의 노사관계에서 노동자들의 경영의사결정 참가가 매우 저조한 상황에 처하여 있으므로 노사관계 주체들이 경영환경이 급변하고 있는 최근의 상황에 대하여 능동적 적극적 협력적으로 대처하지 못하는 등 대처능력 부족을 심각하게 드러내고 있다. 둘째, 이들 기업에서 단체교섭 수준의 사항들에 대하여는 단체교섭 수단으로, 장기전략 수준 및 작업현장 수준의 사항들에 대하여는 노사협의회 수단이 상대적으로 많이 활용되고 있다는 점이 발견되었다. 셋째, 노사협의회를 통한 노동자 경영의사결정 참가방식으로는 좀더 대립적인 분위기를 지닌 단체교섭과 충분한 거리를 유지할 수 있는 분리형의 형태가 참가범위의 확장이라는 면에서 보다 효율적인 것으로 생각되었다.

통신망 진화와 함께 다양하게 변화해가는 통신망 운용환경에 능동적으로 대처하기 위해서는 표준화된 개방형 구조를 지향하는 통신망 관리주고의 설계가 필수적으로 요구된다. 특히, 다양하고 이질저인 통신망 구성요소(NE:Network Element)들로 구성되는 통신망에서는 상호 연동성(interoperability)이 결여되어 통신망 운용관리측면에서 TMN 사용자가 필요로 하는 관리서비스 (MS: Management Service)의 효율적인 지원이 매우 어려원진다. 그러므로, 본 고에서는 국제표준화기구인 ITU-TS(Telecommunication Standardization Sector : CCITT)와 유럽의 RACE(R&D in Advanced Communications and Technologies in Europe) 프로그램 통신망에 취해지는 관리행위에 대한 요구사항을 기술한 서비스구성요소(MSC: Management Service Component)를 TMN 관리계층에 따라 계층화시키고, 관리응용기능 (MAF: Management Application Function)을 기능관점에서 분류한 관리기능영역(FA: Functional Area)들간의 정보흐름을 분석하는 등 Top-Down 접근방법에 의한 통신망 관리구조 설계에 대해서 기술하고자 한다.

In order to deal with severe competition in the construction market of developing countries, large contractors must continually improve their own performance and operation. Performance measurement is the heart of ceaseless improvement in organizations. Key performance indicators (KPIs) play a key role in measuring project management performance (PMP) of large contractors in developing countries. The main objective of this paper is to identify KPIs, which can be used to measure PMP of contractors, and then analyze the underlying relationships of these KPIs in order to gain insight into PMP of large construction firms in Vietnam construction industry (VCI). Literature reviews and the pilot survey provided 30 KPIs. Fourteen KPIs, which have the mean values higher than 3.0, were considered as important KPIs through a questionnaire survey of 32 professionals. Factor analysis of these KPIs was employed to categorize them. The results of the survey revealed that top six KPIs are construction time and cost, owner satisfaction on services and products, and quality management and project team performance. Factor analysis uncovered that 14 top-ranked KPIs can be grouped under six categories, namely: (1) construction input management, (2) owner satisfaction, (3) cost and quality, (4) manpower management, (5) subcontractor performance and (6) equipment management. The findings of this research can be used as a guideline to measure PMP of contractors in Vietnam as well as in other developing countries. Since contractors from a country to the other country may have the same manner to manage construction projects, the results of this study may be useful not only to practitioners and researchers in Vietnam but also to participants in other developing countries.

The widespread use of the Internet has led to the problem of intellectual property and copyright infringement. Digital rights management (DRM) technologies have been developed to protect digital content items. Digital content can be classified into static content (for example, text or media files) and dynamic content (for example, VOD or multicast streams). This paper deals with the protection of a multicast stream on set-top boxes connected to an IP network. In this paper, we examine the following design and architectural issues to be considered when applying DRM functions to multicast streaming service environments: transparent streaming service and large-scale user environments. To address the transparency issue, we introduce a 'selective encryption scheme'. To address the second issue, a 'key packet insertion scheme' and 'hierarchical key management scheme' are introduced. Based on the above design and architecture, we developed a prototype of a multicasting DRM system. The analysis of our implementation shows that it supports transparent and scalable DRM multicasting service in a large-scale user environment.

In this paper, a two-stage and top-down approach of mid-term and long-term R&D planning of public corporation is proposed to incorporate some characteristics of public corporation and to overcome the complexity of the real world planning. Unlikely to R&D planning of private company, the total investiment size of public corporation is institutionally determined. A top-down approach is developed to adopt this feature. The proposed approach has two stages to overcome the complexity. In the first stage, we develop a plan for R&D area by adopting the business area and the public role of corporation. In the second stage, we develop the detailed plan within each area. The proposed approach is applied to develop the mid-term and long-term R&D plan of Korea Gas Corporation.

This study investigate the effects of environmental and organizational characteristics on e-business competence and the influence of e-business competence on export performance in the small and medium sized firms. The development of the research model is based on the literature of e-business and the empirical studies of information technology competence. The data from the survey was analyzed using Partial Least Squares(PLS). The results from the empirical model suggest that e-business competence is affected by environmental uncertainty and market diversity as well as top management support and learning orientation. And, export performance is enhanced by e-business competence.

IT and e-business is a hot issue of the world business and economic communities. The web site is the portal through which most of electronic transactions are conducted today. The main purpose of this paper is to investigate on factors influencing the web site development at the firms in Korea. Survey questionnaires were distributed via email & post to 281 firms that have implemented web site. Out of 44 responded questionnaires, 39 data sets were available for statistical analysis with SPPSSWin 10.1. Factor analysis identified five dimensions of web site development : (1) support of top management, (2) information technologies maturity, (3) strategic utilization of web site, (4) strength of rivalry among competing firm, (5) support policy of the government. Results of this study show that information technologies maturity and strategic utilization of web site positively influence on web site development. But support of top management, strength of rivalry among competing firm and support policy of the government don't influence on web site development. This study may provide a guideline to improve the quality of web site development.

This study will provide a useful information and suggestions regarding new wine drinkers wine selection attributes and preference on wine producing countries to wine distributors, wine producers and marketers in Korea. New wine drinkers showed high preference on sweet wine, rich aroma wine, matured wine and white wine respectively. Regarding wine producing countries, Germany, France and Chile were rated among the top preferred countries by new wine drinkers. Results showed that the reasons for disliking wines were not being used to it as the top reason followed by wine being expensive and wine not being tastes good.
