The nuclear power plant construction project is a large-scale project that involved a daily maximum of thousands of workers. many equipment and laborers involved has been required consistently to minimize the need for safety through real-time safety management. But current nuclear power plant construction site is only managed to access of workers and equipments. The purpose of this study is the owner requirements reflects the characteristics of the nuclear power plant construction project integrated safety management system utilizing active RFID and GPS positioning technology.

Clients ought to Appropriate the cost of quality management for contractors based on Construction Technology Management Act. The costs of safety management and environment reservation are separately estimated. and the quality management cost is added up to secure the construction quality required on sites. However, the sufficient cost for quality management was not allowed to the contractors, due to the viewpoints of the clients that the quality management should be one of the duties of contractors. In addition, an Account-related legislation enacted a provision of the labor cost of quality management as the one that should be included in the indirect labor cost. From the continuous survey the quality management cost is currently estimated by 0.2% of the total project cost and the contractors protest the portion of the quality management cost is insufficient. Thus, this paper aimed to provide the bases of estimation of the actualized quality management cost considering the viewpoint of contractors.

Progress measurement provides project participants with valuable information in terms of 'current status', 'corrective countermeasure', and 'forecast of future risks'. However, the managerial effort (or workload) required to acquire and maintain detailed progress data has been the major barrier to practical implementation. Even though recent efforts in utilizing data acquisition technologies (DATs) have actively attempted to automate the progress measurement process, previous DAT research has only been focused on limited construction tasks or selected technologies. This paper proposes a DAT selection algorithm that automatically assign an appropriate DAT for every commodity item for an entire constriction project. Five different criteria were identified and developed in order to comprehend specific requirements for automating the progress measurement of each commodity group. A case-study and also a survey from practitioners were conducted in order to validate the proposed methodology.

Most construction works in a building site are progressed by many work categories and sub-contractors. Therefore there are many difficult things of management of construction-information because variable occurrences are happened to manpower and material resources. For this reason, various management systems are suggested, but the application of these systems are difficult because only construction company manages these systems and sub-contractor's participation, understanding and financial ability are insufficient. In addition to that, there are other problems such as lost information when it is carried, perversion and distrust of information by hand and lots of time and labor are necessary for collection, analysis, and management of information which are offered for daily report. so the purpose of this study is for improvement of reporting process with making an analysis of productivity effects and an analysis of function and problem of daily report. I intend to suggest the direction of improved daily report system for better productivity of construction work through input information and management of cooperation enterprises.

Korean Peninsula Flora Database (KPF database), developed by T.B. Lee Herbarium of Seoul National University comprises ca. 65,000 accessions of vascular plants collected from Korean peninsula from 1850 to 1945. Among these, material from North Korea (Democratic People's Republic of Korea) is represented with ca. 33,000 accessions. The largest part of this material [ca. 4287 accessions (13%) from North Korea] originates from five Japanese and one American collectors, such as Imai, Hanjiro, Mills, Ralph Garfield, Furumi, Masatomi, Nomura, Naohiko, Saito, Tatsumoto, and Okuyama, Shunki from 1909 to 1942. These data are the third largest holding (13%) of North Korean collections after Komarov, V.L and Nakai, T. A part of scientific report about the results of these expeditions had been published before, but the present publication set it sights on giving a first overview of the itineraries and the materials collected by five collectors in North Korea. Among these, Saito has by far the largest collection with 1,730 specimens, followed by five collectors in order with 1,067, 532, 510, 368 and 370 accessions by Mills, Nomura, Okuyama, Furumi, and Imai respectively.

An installation of the construction lift has a few limitations by many constrains and these have influences on labor productivity, that can be changed by vertical-transportation management. In the super-tall building construction, a management of construction lift operation is one of the most important factor, but existing methodologies depend on skilled practitioners' experiences. And it is true that the expertise resulted by the experiences does not transfer to the next generation. This study is a part of lifting-management simulation development which aims at the optimal construction lift management. A proposed algorithm is focus on lifting time calculation considering an acceleration capability. This research evaluates the result accuracy using comparative analysis on simulation result and field measuring time.

The Internet, the main issue of a new millennium, is being researched vitally for the progress of the construction industry, and the construction industry is considered to be led into a high-value added state-of-arts technology industry through CALS. Even if many construction companies gradually widen the use of the Internet for various purposes such as an electronic bidding system and an e-commerce system, the companies are still demanded to use the Internet more broadly and practically. Hence, the need for a tool for fast decision making and an effective construction management has risen. The PRIMA system has been developed specifically focused on meeting with those recent changes of the construction industry. This system is composed of three parts. Those are Just In Time(JIT) management, integrated application of man power${\cdot}$safety${\cdot}$work management and decision making process based on real-time information in the Internet. The usefulness of the PRIMA system has already been proved in a super-scale construction project. As the Internet environment get improved the use of the tool will be spread out gradually for many construction projects, regardless their size and location.

Establishment and expansion of a FOI regime is a fundamental basis for modern democracy. Informed decisions and supports by the people are critical to establishment of democratic institutions and policies. The best tool to make informed decisions and to ensure accountability is the FOI. For effective FOI, good records management is necessary requirement. This paper observes and analyses the development of the FOI in the U.S., the Open Government policy, and the government records management reforms under Obama Administration to search viable solutions for Korean FOI and public records management reforms. Major revisions and advancement of the FOIA in the United States are examined, especially the revision of the FOIA as the OPEN Government Act of 2007. The FOIA revision enhanced greatly the freedom of information in the U.S. including the establishment of an independent FOI ombudsman by the Congress. The paper also discusses the Presidential memoranda on the Open Government and the FOI by President Obama, the following directives, Presidential memorandum on government records management and the Government Records Management Directive. Major contents of the directives, plans, and achievement are summarized and analysed. Finally, this paper compares the government records management reforms under former President Roh Mu Hyun with the Obama's reform drive. The comparison found that major difference in the "top-down" government records reforms are the difference in democratic institutions such as weak congressional politics, strong bureaucratic obstacles, and relatively weak social and professional supports for the reforms in Korea, while these reforms were similar in terms that they were driven by insightful political leaders. Independent FOI ombudsman and national records administration are necessary for such democratic reforms.
