In this paper, traditional residential architecture in South Korea appear to approach environmental regulation as part of ecological architecture of regional climate controlled environment, according to the characteristics and spatial arrangement, and material to the environment was described as a controlled manner. The scope of this study was not large scale housing construction from traditional chusagotaek, yunjeunggotaek, yangjindang, dokrakdang target was the case. Focusing on examples extracted from Korea first eco-friendly characteristics of traditional residential architecture is an extension of nature to explore space and yard space, and South Korea by way of environmental control that appears in traditional architecture, waterproof, moisture, solar radiation, sunlight, ventilation and air Attributes such as environmental regulation and environmental regulation of space, place and manner of materials were described. Korea's research through more traditional residential architecture of the environmental control and a wide range of environmentally friendly eco-construction was that appeared natural to use energy efficiently, it had been available. Later appeared on the Korea traditional architecture through research on environmental control of environmentally friendly ways to navigate and take advantage of the elements, through continuous research and eco-friendly construction to realize the traditional South Korea could provide a prototype of the modern, I thought I'd had.

In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.

Recently, the need to strengthen the Air Environment Conservation Act and secure alternative heat sources during the winter by carbon neutrality policies has been raised. Accordingly, winter construction, which has safety and quality measures, is emerging as an essential factor. It is believed that eco-friendly tropical type electric hot air heaters will be able to solve most of the problems of winter construction at construction sites, especially prevention of suffocation and fire accidents. In addition, as a result of on-site performance verification, it has secured more than the same performance as the existing curing method, and the curing technology can create an eco-friendly and pleasant working environment while considering safety and construction.

Hospital design technology of Korea has recently been exported to underdeveloped countries through the EDCF business. This business reflects our high technology of the hospital design and the regional features that reflect the natural environments, the architectural features and the architectural technology of underdeveloped countries. In accordance with the trend of the global environmental-friendly design market, introduction of environmental-friendly design is needed in the project of hospital for underdeveloped countries. A result of examining the Bangladesh case, the hospital design for the underdeveloped countries already contains a lots of environmental-friendly design elements which have lots of effect. In addition, these environmental elements already contains the advantage and efficiency of operation. Thus, for the success of the hospital design project of the international assistance business, it is necessary actively to discover the environmental-friendly design elements of the region, and to survey the environmental-friendly construction of the region and to make the guidelines of environmental-friendly hospital design during the feasibility study phase.

Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Apartment residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling construction has a unique characteristic in that the residents are already determined prior to construction execution. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

Recently, the public interest in eco-friendly material and structure has been increasing and many Hwang-toh researches are being actively performed. Hwang-toh is one of the traditional environment friendly construction materials used as a construction and plastering material. Hwang-toh has many advantages as construction material due to its high heat storage capacity, auto-purification, antibiotic ability, and infrared ray emission characteristics. But, currently it has not been developed into construction material and used in modern construction due to its low strength and dry shrinkage cracking prone characteristics. According to the recent researches and study results, Hwang-toh can be used as a natural pozzolanic material like fly-ash or pozzolan. In this study, mechanical properties and structural flexure behavior experiments of slag, recycled PET fiber, and Hwang-toh added concrete are carried out. The test results showed that drying shrinkage of concrete mixed with Hwang-toh has lower compressive strength and elastic modulus than those of control cement concrete specimen, but it has the similar flexural behavior in reinforced concrete beams.

The contamination(stain phenomenon) of natural marble(sipeol, bianko) of art wall of on-site interior finishing system and wall of elevator hall has occurred. The bottom of the art wall of stone junction tile has defects as cracks. To solve these problems, our research team developed eco-friendly complex stone panel(stone 4T + cement board 6T) and high-frequency hot-melt construction method that can construct in winter.

The most important factor when designing coastal and offshore concrete structures is durability. However, concrete in marine environment is exposed to physical and chemical deterioration of seawater, which might easily lead to low quality. The purpose of the present study is to understand advantages of adding ground solidificaton materials by comparatively analyze the seawater resistance of general concrete and environmental-friendly ground solidification materials.

A new algorithm is proposed for the construction of Brezing-Weng-like elliptic curves such that polynomials defining the CM discriminant are linear. Using this construction, new families of curves with variable discriminants and embedding degrees of $k{\in}\{8,16,20,24\}$, which were not covered by Freeman, Scott, and Teske [9], are presented. Our result is useful for constructing elliptic curves with larger and more flexible discriminants.
