For the development of solar thermal power tower plant from the early 80' to today, various kinds of receiver have been tested and evaluated. Most of 1st generation receiver used water/steam as a working fluid to operate steam turbine and now the first commercial solar power tower PS-10 also makes saturated steam. However, to increase thermal efficiency of storage system and to obtain practical use of solar energy, molten salt system have been used from THEMIS project in France at 1984. The Solar Tres plant of 17 MWe power generation will be constructed in Spain and have plan to operate 24 hours in summer. The air volumetric receiver system can be integrated with combined cycle of gas turbine and HRSG and also with steam turbine easily. Therefore, related researches to develop higher efficient solar power tower plant and to operate with stable are widely performed in the world.

This is a positive study for researching of the cognition, realities of composition and utilization, and requirements of the future about green spaces of the urban traditional residences nearby downtown of Taegu. This study is constructed to the actual and servey examination, and the subject areas were Sam-Duk-Dong and Su-Sung-Dong. The results of this study were summarized as follows, 1) The dweller more Preferences anti-artificial and hearing than artificial and visually nature elements. 2) The best plant space was 'Madang', and the kind of best plant was ornamental. The main purpose of plants were admiration and to use as food. 3) The dweller's requirements rather hearing than visually elements. and they preference in indirectly method but they had subconslousness about directly plant plan. Also they want to water space.

Amount used of admixture fare is increasing for concrete economic efficiency and ability security. Security of economic efficiency and ability can expect by use of this admixture fare but is displaying a lot of problems on early age strength hold by hydrate delay relatively. Specially, in the case of construction site, concrete strength can speak that interrelation is high with mold removal of forms time. Therefore, is economical and need examination of plan that can secure robber within 3 days using admixture fare such as fly ash and blast furnace slage differential speech to secure function. In this study, adding liquid admixture within 1% of a binding agent quantity to examine these problem with physical characteristic after hardening ago specially, strength change at standard and air dry curing of observed change in priority. Air dried and water curing total strength enhancement effects appeared by thing which is in case of add test result liquid admixture by below 1% and strength deputy by passage of age could know is not big.

Serious problems of the environment protection and resource exhaustion are exhibited. due to the increase of the construction materials and activation of the remodeling, recently. Especially, most of the advanced countries. recycling plan for the waste concrete is vigorously progressing. The purpose of this study is making advances in the recycling of waste concrete material for use as recycled aggregate to make secondary concrete product. Using recycled aggregates form demolished concrete, we manufactured cement bricks to experiment overall performance in Korean Standard and feasible performances. On the recycled cement, in the case of cement : aggregate is 1 : 7 is satisfied with KS F 4004 : dimensions, water absorption, compressive strength of quality of a standard. So we concluded that it has great feasibility to apply these products to construction industry.

The equipment of a landfill need whole cut off facilities so that leachate generated from the landfill primarily do not leak to the ocean. Also, the whole collected leachate need a consecutive clarification treatment to discharge. A method is considered the best among the three alternatives. The merits of this method are as follows; have no secondary pollution. can cut down the expense of treatment, have good effects on preventing external leakage, don't need a leachate well, reliable quality control and easy post management. The weaknesses of this method are as follows; need a thorough survey about underground water and quality of the soil, need a special process to use as the land.

China's rapidly growing cities offer a unique opportunity to create highly sustainable communities. Architects and their clients, typically real estate developers, are highly focused on strategies that are effective at reducing energy and water usage at the scale of the individual building or within a master plan of multiple related buildings. However, a closer look at energy consumption reveals that transportation uses more energy worldwide than residential and commercial buildings combined. In light of this, it is appropriate that China is making massive investments in transportation infrastructure like heavy rail rapid transit and grade separated expressways, but the end result of these investments to date has been to enable people to live further from where they work and shop rather than closer - while simultaneously not creating walkable communities. Using positive and negative examples from Asia and the rest of the world, this article will investigate the specific urban design policies such as height limits, setbacks, land use restrictions, parking ratios, and parcel size which might change to enable the creation of truly sustainable communities for China's 21st century.

Green Roof Systems are embossed that realize ecological architecture as a substantially alternative plan. So, a Purpose of the study is seeking to optimize expectation effect through the Green Roof System. we set possible object and propose the prototype on the basis of the existing Green roof System technologies. We visualize a proposed Prototype apply various materials and methods. and we analyse the effects of Green Roof System upon our City climate with use energy efficiency comparison the Green roof system with the Concrete Rooftop. We'll Provide the low data for The prospects of City climate improvement through the a ripple effect on Green Roof System and for activation of Green Roof Technology.

Depth-area-duration(DAD) relations are important to hydrological plans and designs for the water resources as well as the flood defence. And these relations have been still in analysis and use today because they can be applied to readily available data. In this paper, rational and consistent DAD models were developed using the multiple regression analysis and basic relationships of area ratio-runoff volume about heavy rainfall occurring in the Im-Jin river basin, 1999. In addition, revised DAD models and curves that can convert a maximum point rainfall to mean area rainfall were developed and evaluated. As results, these models seem to have predictive value in order to plan and design hydrological structures of flood defence in the Im-Jin river basin.

최근 중 소규모의 도시개발, 택지개발, 유통단지, 산업단지, 주택단지 조성 등의 단지개발이 급속히 증가하고 있으며, 이에 따라 재해영향평가 및 사전재해영향성 검토도 증가하고 있는 실정이다. 단지개발은 보통 지구지정 또는 기본계획을 수립하여 개발계획 승인을 받고 실시설계를 통하여 실시계획을 승인을 받는 절차를 갖는다. 이에 효율적인 토지이용계획을 위하여 개발계획 승인전에 수십 회의 토지이용을 변경하고 또한 실시계획승인 전에도 토지이용계획은 수회의 변경을 통하여 이루어진다. 이에 재해영향평가 및 사전재해영향성검토를 초기단계에서 수행하는 실무자들은 토지이용계획의 빈번한 변경으로 인하여 저류지 규모 산정에 어려움을 가지고 있다. 단지개발의 토지이용계획 특성상 투수지역이 다소 있는 단지, 투수지역인 공원 녹지, 불투층인 도로 주차장으로 주로 구성된다는 공통점이 있다. 따라서 최근의 심의 완료된 재해영향평가보고서들을 인용, 각 단지개발의 토지이용계획도를 고려한 저류지 홍수조절용량을 산정하는 경험적이고 통계적인 다중회귀모형을 개발하였다. 금회 유도된 다중회귀모형식은 재해영향평가 및 사전재해영향성검토를 수행하는 실무자에게 행정계획단계뿐만 아니라 개발사업단계에서도 신속하게 저류지 규모를 개략 산정하고, 비전문가인 검토자가 신속히 홍수조절용량의 적정성을 검토하는데 매우 효과적으로 사용될 것으로 판단된다.
