비디오 정보를 사용자에게 서비스하기 위해서는 기존의 범용 파일 서버와는 다른 새로운 개념의 서버가 요구된다. 본 논문에서는 실시간 재생 서비스를 제공하는 개인용 VOD(Video-On-Demand) 서버를 설계하고 이를 Windows NT환경에서 구현하였음을 보인다. 제안하는 개인용 VOD 시스템은 VCR(Video Cassette Recorder) 연산의 지연시간, 사용자 접속 승인 지연시간을 줄였으며 빠른 VCR 연산으로 VOD 시스템에 접속하는 사용자에게 좀더 빠른 데이타를 전송할 수 있도록 하였다. 또한 사용자들의 접속을 원활히 하기 위하여 대화 형태의 인터페이스를 제공한다.

This paper overviews the design of SANique$^{TM}$ -a shred file system for Linux cluster based on SAN environment. SANique$^{TM}$ has the capability of transferring user data from network-attached SAN disks to client applcations directly without the control of centralized file server system. The paper also presents the characteristics of each SANique$^{TM}$ subsystem: CFM(Cluster File Manager), CVM(Cluster Volume Manager), CLM(Cluster Lock Manager), CBM(Cluster Buffer Manager) and CRM(Cluster Recovery Manager). Under the SANique$^{TM}$ design layout, then, the syndrome of '||'&'||'quot;split-brain'||'&'||'quot; in shared file system environments is described and defined. The work first generalizes and illustrates possible situations in each of which a shared file system environment may split into two or more pieces of separate brain. Finally, the work describes the SANique$^{TM}$ approach to the given "split-brain"problem using SAN disk named "split-brain" and develops the overall recovery procedure of shared file systems.

건설사업관리 방식을 도입하는 과정에서 건설사업관리자의 계약적 책임에 대하여 많은 논란이 있어 2002년 건설기술관리법에 손해배상 조항을 개정하였으며, 건설산업기본법에서도 건설사업관리자에게 선관의무를 부과하고 있다. 하지만 CM for Fee의 계약 방식의 경우 건설사업관리자는 컨설턴트 책임을 지니고 있지만, 국내 건설환경으로는 컨설턴트 책임범위에 대해서 명확하게 규정하지 못하고 있다. 이에 본 연구에서는 건설사업관리자의 컨설턴트 책임의 성격인 전문가적 책임 중 선량한 관리자의 주의의무에 대한 이론을 정리하고자 하였으며, 변호사 등 전문가 의무 등을 토대로 건설사업관리자의 선관주의 의무 항목을 제시하여 건설사업관리자에 대한 책임문제를 진단할 수 있는 기초를 제공하고자 하였다. 도출된 항목에 대한 검증을 위해 전문가를 대상으로 인터뷰조사를 실시하여 중요도를 산정하였다.

The aim of this study was to identify perception discrepancies related to organizational effectiveness in childcare center. To achieve this, managers and teachers were treated as two different subjects. Statistical analysis showed that perception influences differed between managers and teachers. Managers were affected by organizational characteristics and director of the organization. On the other hand, teachers were affected by organizational characteristics and the manager of the child-care center. It was established that the different view points of managers and teachers led to a situation where a manager perceived organizational effectiveness in a more holistic and positive light compared to teachers. It is our assertion that in order to run a child-care center efficiently, it is very important to fortify the ability and authority of managers.

아날로그 방송에서 디지털 방송으로 변화되면서 다양한 서비스를 사용자에게 제공하려는 데이터들을 송수신하기 위한 방송 환경이 다양하게 연구 되고 있다. 실시간 방송 환경에서 전달된 데이터는 수신기의 저장장치에 임시적으로 저장되고, 사용자는 그 데이터를 사용 할 수 있게 된다. 실시간 방송 환경에서는 데이터의 일부분이 지속적으로 들어오는 스트리밍 형태로 전송되는데, 이와 같은 실시간 방송 환경에서는 기존의 파일 시스템과 다르게 데이터 처리를 고려할 필요가 있다. 본 논문은 실시간 방송 환경에서 전달된 데이터를 신뢰성을 보장하고, 유연성을 제공 할 수 있는 스토리지 매니저를 제안한다.

The specialty of Construction Manager's work is largely depends on the project progress stage and the type of management work. However, at present, career management system manages only the type and duration of the construction project, disregarding specialty and competence. However, in order to select a right construction manager for the client's needs or project characteristics, career management should be subdivided and managed according to the project progress stages or the types of management. In addition, this career management plan is essential for construction managers to receive appropriate wages for their careers and competences. Therefore, this study proposes a classification system for the integration of career, work, and competency to promote effective career management.

This study develops a mediating model to explore the relationships between organizational characteristics, manager's knowledge, management commitment, user involvement, information quality, and management information system effectiveness in small- and medium-sized enterprises in Vietnam. Adapting scales from previous research, the authors designed questionnaires, which they distributed to respondents in Vietnamese small- and medium-sized enterprises. Also, by employing a meta-analytic path analysis throughout structural equation modelling (SEM) with sample of 356 respondents, authors indicate that organizational characteristics are directly related to management information systems effectiveness. Moreover, manager's knowledge, user involvement, and information quality show their important roles in the increase of management information system effectiveness, yet management commitment does not indicate a similar role in the growth of management information system effectiveness. Bootstrapping is utilized to discover the meditating role of information quality, illustrating that quality information mediates the linkages between user involvement, organizational characteristics, and management information systems. However, the mediating role of information quality in the relationship between management commitment, manager's knowledge, and management information systems is not significant. This study contributes to the management information system literature as well as to enhance MIS effects in small and medium-sized enterprises.

Many researches and projects are implemented about u-IT according to changes of ubiquitous environments in the world. Especially, there are benefits to raise lifestyle and we can develop industry by applying ubiquitous regionally. Also it makes citizen feel comfortable directly. There are many projects to regionally adopt ubiquitous services like u-City model for getting this advantages. RFID technology must be suited to each environment because each RFID tag has different characteristics according to frequency band. We need to integrate bands of RFID to overcome limitations and provide more detail information and services. In this study, we develop the dual band RFID Manager needed adopting u-Zone service for both 13.56MHz and 2.45GHz. The RFID Manager, application software for base station of u-Zone, delivers the information from readers to integrated u-Zone server system.

창업보육센터의 효율적인 운영시스템을 도출하기 위해 창업보육센터 운영시스템에 따른 운영성과 및 보육매니저의 역할에 따른 운영성과에 대해서 고찰하였다. 설문 대상은 창업보육센터에 입주한 기업체로 하고, 분석은 SPSS 19 Ver 프로그램을 활용하여 요인분석, 신뢰도분석, 상관관계분석, 회귀분석 및 매개변수에 의한 회귀분석을 실시하였다. 그 결과 창업보육센터 운영시스템은 창업보육센터 성과에 영향을 미치는 중요한 요인임을 확인하였으며, 이 중 H/W시스템과 S/W시스템 모두가 유의적인 영향을 미치는 요인임을 확인하였다. 그러나 매니저 특성이 창업보육센터 지원시스템과 성과와의 관계를 매개하는 변수인지에 대해서는 가설이 기각되어 반드시 매니저의 특성 요인이 상호간에 영향력을 미치지는 않는 것으로 보인다. 운영성과는 센터에 대한 성과와 입주기업에 대한 성과로 나누어 분석한 결과 매니저 특성은 입주기업 성과에 유의적인 영향을 미치는 것으로 분석되었다.

In order to improve project performance by analyzing the effects of the project manager's leadership competency and the individual competency of the project participants on the project performance, this study examines the effect. In this study, a research model and hypothesis were established to understand the causal relationship between leadership competency, individual competency, and project performance, and a survey was conducted based on this. Overall, it was found that the leadership competency of the project manager and the individual competency of the project participants had a positive effect on the project management performance, the project leadership competency had a positive effect on the completion performance, and the project participant individual competency had a negative effect on the completion performance. As a result of analyzing the effect of the project manager's core competency on the project management performance according to the amount or period of the project type, which is the moderating variable, it was found that there was no moderating effect on the management performance. For the success of the SI project, it is most important to understand the project characteristics well and select a PM suitable for the characteristics, and methods for nurturing excellent project managers should be further studied. In addition, it is expected that it will be possible to identify the effect of project manager leadership competency and participant competency on project performance based on sophisticated research design for more competent PM selection.
