Recently problems of soil and groundwater contamination occur in major construction sites of highway, dam and railways. Contaminants of oil fuels are also detected in the former fuel storage facilities of railroad station and army troops of transportation, etc. These facilities are planned as the sites of commercial infrastructures after restoration from pollutants by the law of soil environment conservation of Korea. In this manuscript, the contents of soil environment conservation law including soil assessment and restoration technology are introduced. Recent changes of soil environment area are also analyzed.

Boeun-gun is hard to develop, because of large numbers of mountains and vast distribution of limited development districts. However it is easy to access from the entire country, and there are large conservation area such as national park and dams. Short-term plans such as attraction of tourists can be established using these advantages. Long-term plans can be planed with stable establishment of continuous considerations and supports. These supports will be rewarded while it demands some time and costs. Private owned mountains can be converted from negligence upkeep of property to utilization of mountains with basic consideration of mountain conservation. This may contribute the essential function of mountain.

The term of ‘the Basic Engineering-Doctrine’implies that “doing more with less”, which had been resulted in a proliferation of “technical slaves”capable of substituting for human labor or animal power during the 1760’s Industrial Revolution, Recently with the downsizing this has been also used to be as a basic concept of every company in Korea. Basically the word is based on a conception of energy conservation for human activities.

The magazine (Bulletin) of "Seikou" was made by conservation engineers to exchange information about the survey and repair work of historic buildings in Japan before World War II. This magazine has 26 volumes in total, and was published periodically four times a year from April 1937 to December 1943. Publisher is Nindokai that is supposed to the forerunner of Bunkenkyo (the Japanese Association for Conservation of Architectural Monuments). Only 3 or 4 organizations except personal possession have it now. And it has a limit to use the contents of the article as a general historical material. So, it was rare that experts and researcher used to the "Seikou". However, this study focuses on the articles of the Korean historic building, which is sometimes appeared in it, although there are few. The purpose of this paper is to clarify the fact-finding of the conservation for the Korean historic building in Japanese colonial period by analyzing the articles in historical records of "Seikou".

Demand Side Management(DSM) is a system to reduce the investment cost for new power plant construction and expansion of supply facilities, power through the investment for the energy conservation and load management. In this study, the trend of the energy environment, the necessity and feasibility of DSM shall be investigated and analysed, so that this study will give a help to select and develope a proper DSM technologies for actual use.

This paper studied Lee Han-Choel's career who was known as the first Korean who had participated in several survey and repair projects of Korean historic buildings as a field engineer during the Japanese colonial era. This paper investigated documents and drawings to find out what he had done specifically in the field, and distinguished the records he had written by handwriting comparison method. In addition, the author analyzed the contents of the articles he published and clarified their significance in Korean architectural history. Through this study, the author expected to clarify Lee's historical status as the first Korean modern expert in the field of historic building conservation, and to supplement the research for the history of Korean during the Japanese colonial era.

Building energy simulation has become a useful tool for predicting cooling, heating and air-conditioning loads for facilities. It is important to provide building energy performances feed back to the mechanical and electrical system operator and engineer for energy conservation and maintenance of building. From this research, we set up the typical weather data of location, basic description of building, geometric modelling data and the specification of Installed primary HVAC system for establishing the simulation model about energy consuming that take place in multipurpose building complex. The simulation tool of building energy - EnergyPlus (DOE and BLAST based simulation S/W), it has been used and accomplished calculations and analyses for evaluating the effect of the system types and operating condition of central HVAC plant on the building energy consumption. In this paper, we offer comparison and simultaneous results those involve electricity consumption pattern and amount between actual operation versus EnergyPlus simulation to the object building during summer season.
