  • On March, 2013, the Government announced the Multiple Prime Contract method will be expanded in public building construction projects. The applying multiple prime contract method has been immersing issue among all stakeholders of construction project. The owner conducts the role of a general contactor as well as owner's original responsibility while construction works being executed by specialty contractors. If the owner has not experience of project management, it should be bring about increasing management cost due to the interface problems among prime contractors. With this reason, it is difficult to administrate the multiple prime contract. So far there has been no methodology of predicting management cost in the multiple prime contract. Therefore, this study aims to enable the operation of efficient multiple prime contracts by developing a model to predict their management costs.

  • Since 2004, the government decided to gradually introduce Actual Cost Data into cost estimate for improving problems of below-cost tendering and to reflect fair market price through competition and carry contract efficiently. However, there are many concerns that Actual Cost Data has not reflected real market price, even that has contributed to reduce the government's budget. General construction firm's burden for labor cost is imputed to specialty contractors and eventually it becomes construction worker's burden. Therefore, realization of Actual Cost Data is very important factor to settle this system. To understand realization level and make short term forecast, this paper drew construction group of which labor cost constitutes more than 95% of direct cost, and compares their Actual Cost Data with relevant skilled workers's unit wage and predicts using time series analysis. The bid price which is not be reflected market price accelerates work environment changes and leads to directly affect such as late disbursement of wages, bankruptcy to workers. Therefore this paper is expected to be used to the preliminary data for solving the problem and establishing improvement of Actual Cost Data.

  • The purpose of this research was to find the present condition on dementia patients clothes design including shapes, colors, construction and details in domestic. This research was for confirming the present problems, suggestions, and basic informations for development dementia patients clothes proto-types. The research methods and process were as follows; 1. The total 20 institutes (5 dementia specialty hospitals, 3 the senior hospitals and 11 nursing care centers) were researched during from June to August, 2005 by trained researchers who had experiences researches. 2. The total 30 nurses and care-givers were interviewed for find the present problems related the dementia patients clothes. 3. The total 39 suits for dementia patients clothes were collected and the design analysed such like shapes, colors, constructions and details by taking pictures and drawing flat works. 4. The present condition about the clothes and problems were found and suggest new ideas. The results were belows; 1 The most of institutes of domestic area had two piece type like general hospital patients' clothes for dementia patients clothes. It means there are no concerning now for old dementia patients. 2. The white colors were firstly used as fabric ground and secondly pale tone or pastel tone colors were used The blue and pink were used as pattern colors. The pattern colors were usually moderate tones. 3. The characteristics of constructions and details were round neckline, buttons, full-length sleeves, straight pants, ankle length pants. 4. New functional fabrics and designs for emotional satisfaction were demanded for dementia patients.

  • Metropolitan rapid transit system plays an essential role in the public transportation system of any large city, and its managing agency is usually charged with the responsibility of storing and managing the design drawings of the system. The drawings are important and historically valuable documents that must be kept permanently because they contain comprehensive data that is used to manage and maintain the system. However, no study has been performed in Korea on how well agencies are preserving and managing these records. Seoul Metropolitan Rapid Transit Corporation(SMRT) is the managing agency established by the city of Seoul to operate subway lines 5, 6, 7, and 8 more efficiently to serve its citizens. By the Act on Records Management in Public Institutions(ARMPI), SMRT should establish a records center to manage its records. Furthermore, all drawings produced by SMRT and other third party entities should be in compliance with the Act. However, SMRT, as a form of local public corporation, can establish a records center by its own way. Accordingly, the National Archives & Records Service(NARS) has very little control over SMRT. Therefore, the purpose of this study is to research and analyze the present state of storage and management of the drawings of metropolitan rapid transit in SMRT and is to find a desirable method of preservation and management for drawings of metropolitan rapid transit. In the process of the study, it was found that a records center is being considered to manage only general official documents and not to manage the drawings as required by ARMPI. SMRT does not have a records center, and the environment of management on the drawings is very poor. Although there is a plan to develop a new management system for the drawings, it will be non-compliant of ARMPI. What's happening at SMRT does not reflect the state of all other cities' metropolitan rapid transit records management systems, but the state of creation of records center of local public corporation is the almost same state as SMRT. There should be continuous education and many studies conducted in order to manage the drawings of metropolitan rapid transit efficiently by records management system. This study proposes a records center based on both professional records centers and union records centers. Although metropolitan rapid transit is constructed and managed by each local public corporation, the overall characteristics and processes of metropolitan rapid transit projects are similar in nature. In consideration of huge quantity, complexity and specialty of drawings produced and used during construction and operation of metropolitan rapid transit, and overlap of each local public corporation's effort and cost of the storage and management of the drawings, they need to be managed in a professional and united way. As an example of professional records center, there is the National Personnel Records Center(NPRC) in St. Louis, Missouri. NPRC is one of the National Archives and Records Administration's largest operations and a central repository of personnel-related records on former and present federal employees and the military. It provides extensive information to government agencies, military veterans, former federal employees, family members, as well as researchers and historians. As an example of union records center, there is the Chinese Union Dangansil. It was established by several institutions and organizations, so united management of records can be performed and human efforts and facilities can be saved. We should establish a professional and united records center which manages drawings of metropolitan rapid transit and provides service to researchers and the public as well as members of the related institutions. This study can be an impetus to improve interest on management of not only drawings of metropolitan rapid transit but also drawings of various public facilities.
