Recently, the scale of buildings has been increasing because of the high-rise trend and complexity of underground spaces. A significant number of steel structures have therefore been adopted for building construction. Since workers need to work in high places to install steel beams, many industrial accidents easily occur during steel-frame work. Furthermore, considering the increasing trend of building steel structures, the safety of the workers during the steel beam erection work is of concern. To improve the safety, a new type of joint, located between the steel column and beam, which can eliminate the need for working at the elevated height during steel beam erection has been developed in Korea. Using the newly developed technology in the construction field, the safety performance needs to be evaluated. This study presented the safety evaluation approach for the newly developed technology from the literature review, and applied the method to a self-supported steel joint. The result showed that applying the self-supported steel joint improved the safety of the steel erection work in terms of working posture, working environment, and risk exposure time.

The train-centric control systems development has some distinct points in that a big size of government budget is in general expended in there and the development duration seems to be long. In addition, the changes are ever made continuously in the capability and operational requirements for Trains. Thus, the impact of the potential changes in the required operational capability on the development activities can induce some type of project risks [7]. As such, proper management of project risk has been one of crucial subjects in the train systems development. All these notes combined together make it the significance of the safety management process be raised further up in the train-centric control systems development. As such, the underlying safety management process should be capable of appropriately handling the potential risks that can be created due to the unexpected changes and the long-term development period. The process should also be complemented for the safety consideration of train-centric control systems, for instance, stop. To study these aspect is the objective of the paper. To do so, a step-by-step approach to analyzing the safety management process is first presented. Then, to enhance the process some necessary and useful activities are added in terms of risk and safety management. Then, to pursue some enhancement on the process, a set of necessary and useful activities are added in terms of risk and safety management. The resultant process is further analyzed and tailored using a design structure matrix method. The resultant process is applied in a train-centric control development as a case study.

The objective of this project is to improve the environment of the estuary dike on the Youngsan-River through Re-landscaping. An estuary dike of the Youngsan-River, the largest in the Orient, was constructed in 1981 and connects Mokpo City and Youngam-Gun province. Twenty years ago, when this dike was completed, this place was one of the famous tourist attractions of Korea. It symbolized the development and growth of Korea. But this dike at present is only a dreary sight as a huge concrete construction element. Therefore, a wall painting on the estuary dike was planned to improve this image. The site, an estuary dike of the Youngsan-River, is located in Mokpo City and its length is about 1,360m. The planning focus of this re-landscaping, which is a proposed improvement design through the analysis of characteristics and problems in conventional facilities, is as follows: (1) Introduction of a wall painting that is a symbol of the sea and river (by the creation of an illusion), (2) Production of the wall painting which is under consideration to create a friendly atmosphere of the circumference view and (3) Preparation of a design to establish an approach to the waterfront. By following these steps, an estuary dike can function as a tourist attractions and can be transformed in to cultural space for civilian. This project is good example of environment design that is completed with the regional residents participation through community input in the planning and initiation of a wall painting. The concept of environment design which involves the residents participation and re-landscaping in Korea has not been established up to now on. However, as this projects has proven, consideration for regional residents is a very important factor for the administrative office and planing specialist to address. In the future, it will have a direct influence on the development of design planning. If the establishment of space that can be accepted by residents with love, affection and self-confidence is possible, environment design in which residents participate actively, can be realized.

Most of solar system dissemination has been focused on domestic hot water system of which utilization to a building is relatively simple and safe than solar heating system. Through the survey on a cause of solar house dissemination failure in Korea, we conclude that design integration and systematic approach method for technology application are the most important element for a successful solar house. KIER(Korea Institute of Energy Research) and Hanbat National University have started new project on a development of Zero energy Solar House, called ZeSH which can be sustained just by natural energy without the support of existing fossil fuel. This is the 1st phase research of 10 years long-term ZeSH plan which develops a low-cost and $100\%$ self sufficient ZeSH. The goal of 1st phase ZeSH research is to get a $70\%$ self sufficiency only in thermal loads. Actual demonstration house, named KIER ZeSH I was designed and constructed as a result of 1st phase research work in the end of 2002. Various innovative technologies such as super insulation, high performance window, passive and active solar systems, ventilation heat recovery system are applied and evaluated to the KIER ZeSH I. A lot of computer simulations had been conducted for the optimal design and system integration in every design steps. Considering all the results from detailed hourly computer simulation, it is expected that at least $70\%$ self-sufficiency in thermal loads which is 1st phase target value can be excessively achieved in actual demonstration house. Besides, many valuable findings from the design and analysis to construction could be established such as collaboration method among the participants, practical design and construction techniques for system integration and the others. The purpose of this paper is to introduce the main findings through the development of KIER ZeSH I project. Practical guidelines in every design step for new low- or zero- energy solar house is proposed as result.
