yongdam multipurpose is under construction to divert a part fo Geum riverlfow to Mankyung watershed and to supply the domestic water to the Chunju region and produce the hydro-electricity. Generally construction of dam by the method of inther-region water transfer affects the quantity and quality of water inthe down streams and reservoirs. The impact of operation plan of Yondgam dam on the quantity and quality of water in the Guem river and Daechung dam was investigated .It was recommended that the discharge of water transfer from one watershed to another should be minimized as much as possible.

Due to the nature of the construction industry, massive and diverse data is generated and collected from each project. It can be classified into a number of variables that specify the distinct characteristics of construction projects. However, a variable is used in different terms depending on the users. This situation plays as a great barrier to effective construction information management and also has limitations to collective research and practice. As a solution, it is essential for developing common and shared variables. In this context, the aim of this study is to define systematically organized standard variables for globally collaborative construction management. The standard variables are identified by bibliometrics analysis with VOSviewer, and the bibliographic data is collected from the Scopus with 13,533 documents about construction management.

This study suggests a safety management model for construction management (CM) suitable to domestic conditions so that inefficiency resulted from the operation of construction projects by public and private indtitutes according to different systems can be eliminated for the securing of systematic and efficient safety managment. Based on the suggested safety management model, this study also develops a safety management information system that can efficiently and consistently manage and maintain a large quantity of information, and give necessary supports in a speedy way in the managing of construction projects.

The value of intangible assets of a company attracts attention in enterprise management environment drastically changing. Following such a trend, many companies have adopted knowledge management. Especially in construction industry of which success of a project is easily affected by the capacity of various participants and work performers, we may find many cases to which the knowledge managements have been adopted. However, the domestic design companies have tended to be late to introduce the knowledge management or have difficulty in effective use of KMS already constructed. This study suggests KMS based on BPM (Business Process Management) and drives its effects to improve problems mentioned above. We drives the expected effects by studying the existing studies and surveying domestic design companies and suggests Prototype for introducing a real system.

This study aims to develop a framework for an accident prediction model leveraging a deep neural network algorithm, specifically tailored for small-scale construction sites. Notably, the incidence of accidents in the construction sector is markedly higher compared to other industries, with a significant contribution from small-scale sites. The challenging nature of construction in urban settings, coupled with the increasing frequency of adverse weather conditions, is likely to escalate accident risks at these sites. Anticipating and mitigating accidents at small-scale construction sites is therefore crucial to decrease the overall industry accident rate. Consequently, this research introduces a Deep Neural Network-based model for forecasting accidents at small-scale construction sites. The framework and findings of this study are poised to serve as a guideline for the safety management of small-scale construction projects, ultimately aiding in the realization of safer, more sustainable construction practices at these sites.

Web-based PMIS (Project Management Information System) has played significant role in construction management processes in Korea. As the use of web-based PMIS increases, regular quality assessment to identify user's requirements is necessary. However, there have been rare research efforts for quality assessment of web-based PMIS. This study aims to assess the quality of web-based PMIS, especially ASP-PMIS (Application Service Provider based PMIS) that is widely used in Korean construction industry. The assessment factors of ASP-PMIS quality were adopted from previous research and empirically confirmed using exploratory factor analysis. ISA (Importance-Satisfaction Analysis), which is a variation of original IPA (Importance-Performance Analysis), were selected for the assessment and analysis method in this research. A total of 253 completed questionnaires, composed of 23 assessment items, were collected from the ASP-PMIS users in Korea (construction managers and constructors), and they were used to analyse the quality of the systems. Some possible contributions of this research are: it introduces a simple and easy-to-use tool for assessing the quality of ASP-PMIS with a set of quality assessment factors that are selected from previous researches and empirically tested; it provides the quality assessment results of ASP-PMIS in Korea so that ASP-PMIS providers in Korea can understand the users' opinion on their systems; it also identified that the urgent factors that require immediate attention to improvement. However, further researches are to be required on the following areas: enhancing the quality assessment factors in terms of their relation to the success of ASP-PMIS and to the users' performance; assessing and analyzing the quality of individual ASP-PMIS; establishing continuous improvement systems institutionally and instrumentally.

Recent new town construction project proouced large numbers of apartment houses using precast concrete (P. C.) panels. l'bst construction companies involved in this project put their management focus on to the individual control of P.C. panel producing plants and the job sites. Little attention was paid to the integrated management of the production. transportation. and im;tallation of P. C. panels. Numerous job site delays experienced in the new town project were largely based on the poor coordination between these three key disciplines of the P. C. apartment construction. This stlldy was initiated with an .intention to improve coordination between these disciplines. Activities of these disciplines were identified and related data were gathered. This was performed through the interv:iews with the personnel involved in P. C. constructlon and through the analy::;is of the related documents and publications. Based on this information. the authors are nolol developing a model IoIhich will provide a foundation for opt:iJnal.ly coorc.inated control of the proouction. transportation, and installation of P. C. panels for apartment construction. In this paper. the authors briefly present intermediate results of this study.
