The production process of construction industry is different from thing of the general manufacturing, likewise various participants make temporary teamwork for success of the project through sharing of information. But, the each role of participants is Individually changed to step in construction process stage and moreover it has complicated, entangled interests. The CM(so it called Construction Management as an abbreviation word) system was inducted for the effective management and operation of construction project. The key of the CM success depends on the cooperative relationship relation to major participants. There are lots of studies and efforts for the performance measures of the CM, however existing performance index is only measured as the viewpoint of project owner. Therefore it needs to make up for balanced view through combination of the four-way view of participants. In this study, we should search for cooperative relationship of project participants, and then we should suggest to define the difference of project in their viewpoints.

지금까지 XML문서는 사용자에게 문서내의 모든 내용을 공개하였지만, 전자상거래와 같은 특정 분야의 경우에는 사용자에 따라 문서의 일부만을 공개하는 것이 필요하다. 따라서, 사용자에게 XML 문서의 권한을 부여하고 권한에 따라 접근을 관리하는 접근 관리 시스템이 요구된다. 이를 위하여 사용자 그룹을 권한 주체의 기본 단위로, XML 문서의 엘리먼트를 권한 객체의 기본 단위로 설정하여야 한다. 그러한 권한 주체의 계층 구조는 DAG(Directed Acyclic Graph) 형태로 표현되고 문서에 대한 접근 권한은 접근 제어 리스트를 이용하여 관리된다. 그러나 권한 주체마다 모든 접근 권한을 표시해야 하기 때문에 엘리먼트 단위의 접근 관리를 위해서는 접근 제어 리스트의 크기가 커지게 되는 문제점이 발생한다. 이를 해결하기 위해서 본 논문에서는 DAG를 완전 k-ary 트리로 변환하여 접근 권한을 부모와 자식 노드간에 상속받을 수 있도록 함으로써 접근 제어 리스트의 크기를 상당히 줄이면서도 권한 주체의 접근 권한이 빨리 알아낼 수 있는 새로운 방법을 제시한다. 성능 분석 결과 새로운 방안이 기존의 전관 제어 리스트에 비해 매우 효과적임을 알 수 있다.

The mixed-use development project like urban regeneration project has been enforced with long period and participation of various stakeholders. For this character, lots of risk could be occurred during the process of project and the project's success or failure depends on the risk management. So the process of identifying and responding to risks in urban regeneration projects should be followed systemically. The risk identification phase is the first step to identify risk factors and define risk's character. One of the risk identification methods, the checklist, is the most practical and well-known one. This study suggests the check list that devide risks classified by stakeholders through analizing tasks of stakeholders and drawing risks. This kind of checklist which handles risk factors classified by stakeholders is an easy tool to identify risks and expected to be effective to find risks for various stakeholders and themselves in the urban regeneration projects.

In most PFI(Private Finance Initiative) projects in Korea, the project management are in charge of the Special Purpose Company(SPC) established for carrying out the project. This paper is a case study about an owner CM executed by the organizations and staffs of SPC itself. : Seoulbeltway (Ilsan $\~$ Toegaewon) Private Investment Project. In time management area, the SfC was the leader of project management throughout the life circle - plan, design, permit, construction, operation and maintenance - beyond the schedule manager's role. In cost management area, the methods of reducing the total costs by VE, new technologies, etc. has been needed assuming the construction risks were subject to SPC.

The curtain wall engineering of local high-rise buildings consists of many phases such as design, curtain wail design, manufacture, procurement, construction and facility management, each of which also involves many' actors such as architect, curtain wall consultants, manufacturers, contractors, and facility managers. Moreover, the method for controlling the C/W process of each participant is needed. Eliminating wastes and problems existed in the C/W process can be more effective. What is more, it is necessary to improve the efficiency of the current process and to strengthen the competence through application of SCM to the C/W life-cycle. In addition, it is important that a ]ot of information transfer smoothly and share through information system. Therefore, this study aimed to propose the scope of application and the improvement directions in applying Supply Chain Management concept.

This study analyzed the financing ratio by operation fund financing method and their impact on management performance according to the establishment operation management entity of the medical institution. For the analysis method, ANOVA, logistic regression, and regression analysis were conducted using financial information registered with HASPA.The results of the study, The ratio of gross revenue to operating funds differed significantly depending on the establishment operation management entity. In addition, it was found that the financing ratio of each operation fund financing method was significantly related to the management results(deficit, surplus), and the impact of the operation fund financing method on management performance differed according to the establishment operation management entity. As a result, the management of operating funds of medical institutions is deemed appropriate to apply cost management first considering the ratio of revenue to operating funds, and then to utilize internal operating funds.

Information technology has affected various industries, and the construction industry is one of those. In construction industry, the operating body for maintenance is trying to implement more systematic management skill for public facilities in order to minimize the life cycle cost. For more efficient maintenance system, first, the target facilities were selected and the present condition of their systems was estimated. And, the implementation plan of new system was proposed based on them. Accordingly, the new system managed by working-level personnel can supplement the weak points in the current system.

최근 해안송림에 대한 관심이 높아지고 있고, 이를 효과적으로 보전, 활용해야한다는 목소리가 높지만, 국내에서는 이러한 해안송림이 어떻게 변천되고 지역에 어떻게 기능해 왔는지 아직 알려지고 있지 않다. 본고는 해안송림의 기초연구로서, 하동송림을 대상으로 이러한 해안송림의 사회적인 기능과 관리문제를 검토한 것에 있다. 하동송림을 사례로 조사한 결과, 해안송림은 송림이 지역과 밀착함으로써 주민의 레크레이션기능은 물론 외부관광객을 끌어들일 수 있는 지역발전의 중요한 소재가 될 수 있는 것으로 나타났다. 또한 해안 송림이 지역주민의 일상생활과 밀접히 연관되고 지역발전의 한 축으로서 기능하면서, 송림에 대한 관리 및 주체의식이 높아지는 것으로 나타났다. 이러한 지역발전의 실질적 기능 및 자연스러운 관리의식의 고양은 일반 공원이나 원거리 해안림 등에서는 쉽게 나타나지 않는 것으로서, 마을 숲(해안송림 등)이 갖고 있는 하나의 중요한 잠재력이 아닌가 생각된다. 그러나 관리측면에서는 하천오염이 해결되지 않고, 송림확장계획이 중지되고, 소나무재선충 방지책에 의문에 제기되는 등 적지 않은 문제가 나타나고 있다. 또한 이러한 문제발생의 원인으로는 해안송림에 대한 기본적인 인식의 부족, 책임 있는 관리주체의 부재, 구체적인 연구의 부족 등이 검토된다. 해안송림의 기능과 식생은 고정되어 있는 것이 아니라 지역 환경에 따라 끊임없이 변화되는 것에 있어, 변화에 대응하는 개발논리가 필요하다. 따라서 이러한 특수성을 일반적 임업관리나, 시설보수 차원에서의 접근은 소중한 지역의 자산과 발전기회를 잃은 거와 다르지 않다. 소중한 지역자원의 가치를 빛내고, 보다 효과적인 활용을 위해서는, 보다 체계적이고 파지티브한 관리 및 활용 정책이 요구되는 것에 있고, 이를 위해서는 책임 있는 관리주체를 조직하는 것과 함께, 토지사병에 기초한 송림의 이용 및 식생 변화에 대한 연구가 필요한 것으로 판단된다.
