The long-term repair program is significant as the execution standard for apartment in repair construction, and provides the basis for effective facility management through appropriation reserve and preventive maintenance. Considering its importance, the government legislates the items, cycle, and ratio for long-term repair. However, the frequent changes, controversies on repair, and difficulties in using appropriation reserve are caused as the items have not been revised on time reflecting up-to-date construction technologies. In order to resolve these problems, it is required to improve the standard by evaluating the appropriateness of repair items throughout the analysis of actual conditions. This study aims to suggest the revision plan for the criteria with the major items based on the status identified by the actual long-term repair programs and historical repair construction data. To do this, the adoption ratios of items to program are reviewed by collecting the real cases of the long-term repair programs. Developing improvement plan was approached in two ways such as "exclusion method" deleting minimum unnecessary items and "selection method" sorting out items with high adoption ratio and evidence of repair in a positive manner. Aa a result, the major items were identified as 118 items and 73 items by exclusion method and selection method respectively from the current 147 items. The outcomes of this study are expected to contribute enhancing the practicality of the standard in that the regulation for long-term repair program should periodically reflect the status of currently applied construction methods and materials.

Plant construction projects usually take much higher uncertainty and risks than the projects from other domains. This implies the importance of plant construction project management should be more emphasized than the other domain. Especially, the overall successes of the projects often depend on the performance of process planning and scheduling performed at the initial stage of the project. However, most plant construction projects suffer great difficulties in establishing proper process planning and scheduling timely because of unstructureness and dynamicity of environment of the project itself In this paper, we propose a knowledge-based process planning and scheduling approach in a plant construction domain to cope this problem. First, we modulize process planning knowledge and present the knowledge representation scheme. Second, we propose an inferencing mechanism to build a process planning for plant construction based on the represented process planning knowledge. Since our approach automate the initial process planning, which was usually done by manual way, it can improve the correctness and also completeness of the process plan and schedule by reducing the time to plan and allowing simulations on the various situation. We also design and implement this our approach as a real working system, and it is successfully applied to real plant construction cases from a leading construction company in Korea. Based on this success, we expect our approach can be easily applied to the projects of other areas, while contributing to enhancement in productivity and quality of project management.

Practical and efficient application of lean construction, which has been proposed as an alternative to the limitations of traditional construction management methods, was developed to facilitate application on site and improve productivity through the fusion of traditional construction management methods. The concepts of Lean Time and Lean Cycle Time, which are the principles of lean construction, were introduced to eliminate waste and smooth flow production and pursuit of perfection, and the goal of establishing and improving the criteria for measurement and improvement was established and the information collection template was configured and applied to ensure reliability of measurement and analysis. Based on this, the project feasibility, reliability, and continuous improvement process were applied to the Field case to verify its effectiveness.

$\lceil$The Construction Technology Development Master Plan$\rfloor$ aimed to promote construction technology R&D and to use its result efficiently is a legal plan based on Construction Technology and Management Law and established every five years. Now $\lceil$The 3th Construction Technology Development Master Plan(The 3th Master Plan)$\rfloor$ is establishing by MOCT(Ministry of Construction & Transportation) because the 2th Master Plan is completed at 2002. The 3th Master Plan suggests 'Establishment of construction environment leading the world-wide construction market' as a long-term vision, and also presents basic targets ; 'Improvement of competitiveness through conducting construction project efficiently', 'Transform into technology-oriented industry'. It consists of 7 fields and 25 main subjects. The 7 fields are construction manpower, production system, environment, safety, construction information, construction engineering, construction R&D.

During road construction, minimizing haul and return distances as well as keeping a balance between cut and fill quantities are two of the key tasks for earthmoving operation planning. The result of the earthwork planning has a significant impact on the construction cost and duration. Although there have been research efforts regarding optimized earthwork planning using linear programming, the current practice of selecting earthwork planning methods typically depends on a field manager's intuitive and/or experimental knowledge. Furthermore, there is no system considering earthwork influential field factors including the transportation distance, the earthwork quantity, and the recycling ratio of earth volume. Therefore, this research focuses on the development of such a model for planning the optimized earthwork to increase the efficiency of a road construction. The proposed model is developed based upon the transportation problem method which is a part of Linear Programming. The application result of optimization model on a case study shows that the duration and cost for earthwork ha sbeen reduced approximately 19% and 11% respectively

Disasters have been diversifying and the scale of disaster has been increasing worldwide due to the global warming and urbanization. Consequently, it is essential to establish the systematic disaster management because the scale of damages has been rapidly increasing. Nowadays, the importance of the standardized disaster management have been realized internationally due to the 9.11 terror and Tsunami. Also, the activities of research and development to utilize and establish the disaster management standards have been increasing. This study mainly focused on generating an efficient operating manual to support the systematic disaster management of the central administration office based on disaster management standard in South Korea. Firstly, the activities and status of disaster management performed by the central administration office were investigated. Accordingly, libraries of work, functions, organizations, references and behavior for disaster management were designed. Then, a method to make the efficient operation manual based on the constructed libraries was presented to maximize the efficiency of disaster management. This emergency operation manual could support the systematic disaster management by defining the work, function, references and the codes of conduct. Thus, central administration office would be able to define methods and procedures from preparation to recovery through the utilization of the operation manual.

양봉관리 방법이 양봉 농가마다 조금씩 차이가 난다. 그것은 봉장이 다르고 또한 토질과 기후도 다르가. 그리고 환경 조건도 다르며 따라서 양봉가의 성격과 양봉의 상태도 강군과 약군으로 달라지기 때문에 관리방법도 다르기 마련이다. 1월 양봉관리는 작년을 결산하고 새해는 더욱더 알찬 계획을 세워 풍성하게 수확을 할 수 있는 준비 하는 달이다. 1월의 봉군 관리는 봉군의 상태와 환기에 중점을 두어야 한다.

Although waste management in construction industry has a significant impact on both economical and environmental issues, the current level of waste management performance in Korean construction is reported as relatively low. In this context, this study aimed to suggest the considerations for the improved construction waste management guideline, which leads to the effective waste management on a construction site. In order to reach this goal, the existing domestic construction waste management guidelines were analyzed based on the criteria of the environmental management procedure of ISO 14001. These considerations were described in three aspects such as "planning", "implementation and operation", and "checking and corrective actions".
