The construction craft workers have been getting older and have become drained, in spite of the vital factor that it directly affects productivity and quality as a final producer. This situation in the construction industry is ultimately due to evasion of performances by young craft workers. Therefore, the aim of this study is to propose the certification and level system of construction craft workers and to extract young craft workers from the market for construction craft workers so as to supply and demand high quality of craft workers. First of all, the present status and problems of the domestic construction craft workers are considered in this study. Furthermore, the appropriate way to establish its certification and level system is suggested from the Interview with experts, as well as references of German and Australian case. The revitalization of certification and level system provided in this study is expected to ensure that the craft workers are not simple laborers, but are required the professional knowledge and skill. Besides, it will lead to strengthen specificity and to break from aging, by taking young and qualified craft workers into the construction industry. Also, it will promote an employment stability by connecting the social security system.

The purpose of this study was to make clear considerations in the planning of community housing and the roles of coordinators. Seongmisan village, a representative urban community village in Seoul, was selected for this study on problem solving between residents and opinion coordination between residents and coordinators. For this qualitative research, 2 residents and 2 coordinators answered 'open questionnaires' on prior basic planning, land purchase, financing, architectural planning, construction and inspection, and actual living conditions thereafter. They were each interviewed for 2 hours at a time that was 14-16 months after the residents started living in the new houses, and the records were transcribed. The following was the result. 1) The residents, who ruled the steps of prior basic planning and land purchase, did not have sufficient information or knowledge of the construction of community housing, so that they faced difficulties especially in the legal and financial aspects. 2) The coordinators participated in the project at the steps of architectural planning and construction. The residents accepted the coordinators' opinions on the choice of floor and position, and the coordinators listened to the residents' opinions on individual plans and finishing materials. In the construction step, however, there was conflict between them, and dissatisfaction occurred on the completion time and construction cost. For the successful construction of community housing, a professional coordination company needs to join the project to establish a system of opinion coordinating from the step of prior basic planning to the step of afterconstruction management.

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.

Visual inspection works are very important part of facility maintenance and management life cycle as a step of creating base data for decision making and maintenance and repair. But currently, visual inspection works have been performed unefficiently and unreliably as works on hand, duplication of works, decisions of defect state, unutilization of inspection history, lack of professional and so on. In this research, we developed visual inspection system that processes inspection work efficiently and provides reliability of inspection output, as a target of bridges, tunnels, underground roadway on national road. We defined problems through visual inspection work analysis, examined the solutions and reflected to functional design of system. We will plan to utilize this system in HMCS(Highway Maintenance and Construction Service).

A historic urban landscape has to be preserved wholly, not only as a cultural heritage site, but also as an environment and a neighborhood. However, cultural heritage sites have their own unique social-commercial environments, and these are not easy to integrate during the preservation process even though they are located in the same area. To examine ways of overcoming the difficulty in integrating the preservation of heritages, this study analyzes the historic urban landscape preservation of St. Augustine, Florida in the United States. The preservation of St. Augustine's historic urban landscape can be identified by its unique system of government-academy cooperation. For integrated preservation of the historic landscape of St. Augustine, Florida's state government owns the properties, which are not designated but have a heritage value, and are located next to the nationally designated heritage sites. The properties receive trust administration by the University of Florida. This cooperation between the government and the university can benefit both stakeholders. To the government, the relationship gives the benefit for professional, long-term management for the properties and their environments. To the university, the cooperation provides a place for practical education, funding, and opportunities for research and management. The government-academy cooperation model argued for this study can be applied to many Korean historic cities' urban landscape preservation planning.
