The BIM design is expected to expand to the domestic and overseas construction industries, depending on the effect of construction productivity and quality improvement. However, with the obligation of Public Procurement Service to design the BIM design, it includes a design error and the problem of utilization of 3D design by choosing a simple 2D to 3D remodelling method that can not be modelled in 3D modeling or use of the construction and maintenance phases. The results reviewed by BIM design results were largely underutilized and were not even performed with the verification of the error. In order to resolve this, one must develop the check system that secures the quality of BIM design and ensure that the reliability of BIM results are available. In this study, it is designed to develop a program that can automatically verify the design of the BIM design results such as violation of the rules of the BIM design, design flaws, and improve the usability of the BIM design. In particular, this programs were developed not only to identify programmes that were not commercially available, but also to validate drawings in low-light computer environments. The developed program(LH-BIM) store the information of attribute extracted from the Revit file(ArchiCAD, IFC file included) in the integrated DB. This provides the ability to freely lookup the features and properties of drawings delivered exclusively by the LH-BIM Program without using the Revit tools. By doing so, it was possible to resolve the difficulties of using traditional commercial programs and to ensure that they operate only with traditional PC performance. Further, the results of the various BIM software can be readily validated, which can be solved the conversion process error of IFC in the case of SMC. Additionally, the developed program has the ability to automatically check the error and design criteria of the drawings, as well as the ability to calculate the area estimation. These functions allow businesses to apply simple and easy tasks to operate tasks of BIM modelling. The developed system(LH-BIM) carried out a verification test by reviewing the review of the BIM Design model of the Korea Land & Housing Corporation. It is hoped that the verification system will not only be able to achieve the Quality of BIM design, but also contribute to the expansion of BIM and future construction BIM.

최근 국외 건설사들은 BIM 설계를 통하여 건설 생산성 및 품질향상의 효과를 얻고 있다. 반면에 국내의 BIM 설계는 추가 비용 및 전문 인력부족 등의 문제로 침체되어 있는 실정이다. 건설경기의 불황 등의 이유로 건설시장 규모가 축소되어 있는 시기인 만큼 일차적으로 공공기관을 중심으로 BIM 설계를 활성화하여 설계 초기 단계뿐만 아니라 시공분야까지 BIM을 적극적으로 도입하고 그에 따른 성과의 확산 및 국내 BIM 기술발전을 도모할 수 있어야 한다. 본 연구에서는 BIM 설계 활성화를 위해서 일차적으로 공공기관의 BIM 설계를 활성화시킬 수 있는 방안을 제시하였다. 이를 위하여 한국토지주택공사(LH) 사례를 통하여 BIM 설계 추진상의 문제점들을 분석하였고, 그에 따른 개선방향 및 구체적인 설계 적용 방안을 제안하였다. 또한, 제시된 방안을 단계적으로 수행하기 위해 "LH BIM 설계 적용 로드맵"을 수립하였으며, 그에 따른 기대효과를 제시하였다. 제안된 연구 내용은 한국토지주택공사에서 시범사업으로 적용될 예정이다. Recently, foreign construction companies through the BIM-design have the effect of improving productivity and quality construction. On the other hand, domestic BIM-design is a little depressed because of lack of additional costs and professional personnel problem. The construction industry of recession, as reasons of construction market is downsizing. First must, enabling the design in public institutions, mainly BIM.. Design for BIM the construction sector, as well as an early stage actively introducing and spreading of the performance of him and domestic BIM technology should be able to promote the development. Public institutions in accordance with this study presented measures that can stimulate the BIM design on LH. To that end, the public agency's design were analyzed, and suggested the Improvement and Application of the four aspects for Modular Coordination BIM Design. Also, gradually formulate a "road map for public institutions applied design bim" in order to carry out the plans put forward and presented the expected effect of him. The proposed work was public institutions will be used as a pilot project in Korea Land Housing Corporation.

도시재생을 효율적으로 수행하기 위해서는 전국적으로 쇠퇴정도를 파악하고 지구단위별 쇠퇴지역 및 잠재력 등을 평가할 수 있어야 한다. 이를 위해서는 다양성과 복합성을 고려한 공간정보 기반의 종합적 진단체계의 구축이 요구된다. 본 연구에서는 이러한 진단체계 구축의 일환으로 도시재생 종합정보시스템 아키텍처를 설계하였다. 시스템 개발을 위해 일차적으로 시군구단위 쇠퇴진단지표 DB를 구축하고, 쇠퇴진단시스템을 개발하였다. 또한 시스템의 고도화 추진방안을 제시하였다. DB 구축은 전국 시군구를 대상으로 하였으며 이에 대한 메타데이터를 구축하였다. 시스템은 Open API 기반으로 확장이 용이하도록 설계하였다. 그리고 RIA 기술 기반의 직관적인 UI를 구현하였다. 시스템의 주요기능은 지표관리, 진단분석(시군구단위 쇠퇴진단), 정보공개 등으로 구성하였다. 고도화 방안에서는 도시재생 DB의 공간적 관계성을 고려한 정보모형을 설계하고, 시멘틱 웹의 적용방안을 제시하였다. 지구단위 분석모형의 개선방안으로 지구단위 분석모형, GIS 기반의 공간분석 플랫폼, KOPSS 분석 모듈의 연계 활용방안 등을 제시하였다. 도시재생 종합정보시스템의 활용을 통해 도시쇠퇴의 현황 파악 및 재생대상의 우선적인 수요파악을 통해 정책결정이 용이해질 것으로 기대된다. In order to achieve an efficient urban regeneration of the nation, it is required to determine the extent of decline nation-wide and the declined areas for each district and also to evaluate the potentials of the concerned areas. For this task to be accomplished, a construction of a comprehensive diagnostic system based on spatial information considering diversity and complexity is required. In this study, a total information system architecture for urban regeneration is designed as part of the construction of such a diagnostic system. In order to develop the system, a city and district level unit decline diagnostic indicators has been constructed and a decline diagnostic system has been developed. Also, a scheme to promote the advancement of the system is proposed. The DB construction is based on the city and district level nation-wide and metadata for the concerned level is constructed as well. The system is based on the Open API and designed to be flexible for extension. Also, an RIA-based intuitive UI has been implemented. Main features of the system consist of the management of the indicators, diagnostic analysis (city and district level decline diagnosis), related information, etc. As for methods for the advancement, an information model in consideration of the spation relations of the urban regeneration DB has been designed and application methods of semantic webs. Also, for improvement methods for district unit analytical model, district level analysis models, GIS based spatial analysis platforms and linked utiliation of KOPSS analysis modules are suggested. A use of a total information system for urban regeneration is anticipated to facilitate concerned policy making through the identification of the status of city declines to identify and the understanding of the demands for regeneration.

Recently, prestressed H-Beam bridges with external unbonded Tendons are increasingly built. The mechanical behavior of prestressed steel H-beams is different from that of normal bonded PSC beams in a point of the slip of tendons at deviators and the change of tendon eccentricity that occurs, when service load are applied in external unbonded steel H-beams. The concept of prestressing steel structures has been widely considered, in spite of long and successful history of prestressing concrete members. In the study, The flexural test on prestressed steel H-beams has been performed in the various aspects of prestressed H-beam including the tendon type and profile. The load was plotted against the deflection and the strain respectively in the steel beam and prestressing bars. The value expected with the equation of internal force equilibrium and compatibility between the deflection of the bars and the H-beam was found to correlate well with the measured data. 본 연구에서는 기존에 사용된 H-Beam 교량을 편향부와 외부 긴장력을 도입하여 보강효과에 의하여 지간을 증가시킬 수 있고 단면을 축소할 수 있다는 근거를 제시하였고, 유연도법을 이용하여 편향부의 효과에 의한 추가 긴장량을 산정하였다. 또한, 실험변수(긴장량, Tendon의 개수, 편향부의 유 무)에 의해서 표준실험체(기존 H-Beam)와 외부 긴장된 H-Beam 등 5개의 실험체를 제작하여 휨 실험을 실시하여 외부 긴장된 H-Beam의 역학적 거동을 연구하였다. 특히, 보강효과 및 편향부의 효과를 실험적으로 검증하였다.

한ㆍ중 양국의 회사법은 이사의 책임을 매우 엄격하게 규정하고 있으며 대표소송제도를 인정하고 있지만 요건이 어렵고 복잡하여 활용하기가 쉽지 않다. 향후 주주대표소송을 활성화하기 위해서는 제소요건을 간단하게 하고 소액주주들의 정보부족, 전문성부족, 과다한 비용부담 문제 등을 해결할 필요가 있다. 특히 미국이나 일본의 경우와 같이 제소요건을 단독주주권으로 하고, 제소주주의 담보제공의무가 대표소송제기를 저해하지 않도록 조치할 필요가 있다. 그리고 일반주주는 대표소송을 제기할 수 있는 정보수집도 곤란하고 소송수행에 있어서 입증책임도 부담해야 하기 때문에 회계장부 및 서류의 열람청구요건을 완화하고, 검사인 청구권도 행사하기 쉽도록 완화할 필요가 있다. 또한 원고주주는 승소로 인한 직접적 이익도 없으며 상당한 비용도 부담해야 할 것이므로 주주대표소송의 활성화를 위해서는 이에 대한 배려가 요청된다. 대표소송으로 인하여 기업경영의 건전화는 도모할 수 있지만 책임추궁의 공포 때문에 이사후보자의 선정이 쉽지 않고 이사의 경영행동은 위축을 받을 수 있는 것이 사실이다. 이사는 이러한 공포에서 벗어나 적극적이고 대담한 경영을 하여야만 회사뿐만 아니라 사회적 이익을 향상시킬 수 있는 것이다. 한ㆍ중 양국은 이러한 과제에 대하여 향후 더욱 활발한 교류와 공동연구를 진행해야 할 것으로 생각된다. In recent, we discussed how to enhance the role of directors and the board of directors. As the result, it was generalized that directors are responsible strictly or easily to corporation for their management in error, and that shareholders derivative suit against directors is instituted often. The suit is instituted by shareholders when the corporation does not sue against directors who did illegalities and injuries on corporation. This suit has been adopted in Korean Commercial Law since 1962 in order to protect corporate profits from damages caused by directors. Nevertheless, before 1998, there was no case that derivative suit was instituted. So that, Korean Commercial Law was revised to activate the suit. After that, with the first case of Che-il Bank, a lots of famous derivative suit were instituted against directors. We expect the suit will be very popular in Korea. But in this situation, we have to worry about several problems. Especially, because of heavy burden of directors liabilities, most of corporations are very hard to find out a capable and proper candidate to be a director, and in managerial activities, directors have a tendency to escape a positive management in stead of expecting big earns. To solve these Problems, we discussed on the activation of derivative suit and the reduction of directors liabilities in this study, for example, business judgement rule in American system and the revised bill of Korean commercial law in 2008. Chinese corporation has the strict liabilities system of directors and shareholders derivative suit. But the two system has no flexibility to use, actually it is very difficult to apply. We propose that Korean and Chines scholars have to exchange opinion on the subject in future.

도시재생 업무분야에서 정보체계의 실질적 활용을 도모하기 위해서는 특화된 정보생산 및 관리 모형이 필요하다. 도시재생 종합 DB는 도시 쇠퇴진단, 잠재력 평가, 우선대상지 선정 등 업무 수행을 위해 요구되는 정보수요와 전문가 및 일반인을 대상으로 하는 다양한 서비스 수요에 기반하고 있다. 본 연구에서는 기존의 연구 성과 및 현재 진행 중인 시스템 모형을 분석하여 구축대상 정보를 구성하고 이를 공간정보 기반에서 재구성하여 효과적으로 활용할 수 있도록 정보 모형을 수립하고 구현방안을 제안하였다. 제시된 정보 모형을 통해 도시재생 정보의 활용성을 높이고 도시재생종합정보시스템의 기능을 확장시킬 수 있을 것으로 기대된다.

NAFTA의 投資에 관한 條項과 韓ㆍ中ㆍ日의 投資協定 比較硏究

梁東錫(Dong-suk Yang) 한국기업법학회 2009 企業法硏究 Vol.23 No.2

This study examines the investment chapter of NAFTA and the bilateral investment treaties of Korea-China. of Korea-Japan, and of China-Japan. The three North American countries succeeded in establishing NAFTA. The investment chapter of NAFTA establishes minimum standard of treatment for NAFTA investors and investment which is treatment in accordance with international law, including fair and equitable treatment and full protection and security. NAFTA investors and their investments are entitled to the better of national or most-favored-nation treatment from governments. NAFTA prohibits various investment performance obligations. and generally prohibits direct or indirect nationalization or expropriation of NAFTA investments. And NAFTA has created a highly innovative and increasingly controversial investment dispute settlement system. On the other hand. Korea, China and Japan established only the bilateral investment treaties between each two countries in recent year. However there were no FTA between the three countries, the BIT would be a network which can make a strong economic block in the North East Asia. I hope this study will be applied to establish a North East Asian Economic Block, as NAFTA.
