Asan Oeam village is a town that has been formed since about 500 years ago. It is a folk village centered on Yean Lee and designated as National Folk Cultural Property No. 236. However, the original shape of the thatch, which has regional characteristics, is disappearing. Therefore, I want to study the architectural characteristics of the house which is well preserved in the original shape. The Genjaegotaek is located in the center of the Oeam village. The composition of the house consists of a Munganchae, Salangchae, Anchae, Sadang. The Anchae is an 'ㄱ' shaped house, and it is shaped like a 'ㅁ' which is opened by facing. The wide yard in front of the Salangchae is made of strangely shaped rocks, a hundred-year-old pine, old pagodas, ponds, pavilion. Outside the main gate, there is an 'ㅡ' shape thatch on the west. The Galabjib of Geonjaegotaek is a servant house, and the shape is a ㄱ type. The plane remained well in its original shape, thatch is consisting of a kitchen-room-daecheong maru-room. A Galabjib of Geonjaegotaek can not represent all the thatch of a Oeam village. However, it is expected that this study will be used as a basic data when the study by the thatch in this area is conducted through the analysis of the type.

In this study, a dwelling type of Korea and Japan was compared, and consumption rate of domestic timber and its usage was also investigated. In Korea, dwelling type of apartment which constructed by iron and steel-concrete is main shared, but a detached house which is shared at 60% of dwelling type of Japan is mainly constructed by timber. And the rate of the consumption of domestic wood in Japan is 73%. In Japan, there is an effort to substitute imported wood to domestic timber through the promotion of using of domestic timber. Whereas the needs on using of domestic timber gradually emerged. So, the legal about sustainable use of wood is approved by the National Assembly on May 2012. There is not active movement in the aspect of using of domestic timber yet. These causes to the geographical and environmental characteristics, but industry, policy, and the difference of recognize on domestic timber utilization is thought to do greater influence. Hence, it is recommended to make a portfolio of both balanced domestic timber usage and the change of awareness of people by referring to the example of Japan.

This study analyzes the contribution of hanok that construction in reducing greenhouse gas (GHG) emissions in Korea by calculating the carbon storage of hanoks and comparing it to different housing types in Korea. The hanok is a traditional Korean house. And it were first designed and built in the $14^{th}$ century during thd Joseon Dynasty. According to our results, the number of hanoks in 2016 was approximately 547,085 which was accounting for 7.8% of the total construction market, This study found Gyeongbuk with 95,083, Jeonnam with 88,981, Gyeongnam with 76,388 and Seoul with 43,519 hanoks. According to the GHG Inventory Report for 2016, Korea's total annual GHG emissions amounted to 650 million $tCO_2$, with the carbon stocks in hanoks amounting to 19.2 million $tCO_2$. This accounts for 2.8% of Korea's total GHG emissions and 46.1% of the carbon absorbed by forests. Our results show that hanoks store four times more carbon than light-frame-wood-houses, and 15 times more carbon than concrete-reinforced and steel-frame houses. The main factors causing the hanok industry slowdown are the high construction costs, lack of government support, and insufficient knowledge of hanok architecture. Therefore, to further increase the carbon stock of hanok, more research is needed to improve the technical use of wood and reduce construction of the hanok and prepare legal and institutional arrangements related to hanok industry.

Elementary education is the most fundamental education phase to cultivate a minimum natural quality for basic people life. Because elementary school is a very important step to be a base of lifelong education, it has to lead students to develop a capability of information utilization and rear the ability of self-leading study. Accordingly the elementary school library must be made and managed to cope with a new environment of education and information, as well as it must be a appropriate facilities for the contents of the 7th course of study : The aim of the 7th course of study is to rear the autonomous and creative Korean who lead the age of globalization and information-oriented. It is an ideal that the school library has a separate building for itself as the general information center but it is not easy to do in our conditions. Accordingly when it Is located in a school house, it has to be at the center within easy access of other related rooms such as a classroom and school house. Therefor making a plan and designing a school building, the school library has to be considered preferentially as a main facilities in order to make a school to accept the future.

People currently spend more than 80% of their time indoors; therefore, the management of indoor air quality has become an important issue. The contamination of indoor air can cause sick house syndrome and various environmental diseases such as atopy and nephropathy. Formaldehyde gas, which is the main contaminant of indoor air, is lethal even with microscopic exposure; however, it is commonly used as an adhesive and waterproofing agent for indoor building materials. Therefore, there is a need for a gas sensor capable of detecting trace amounts of formaldehyde gas. In this review, we summarize recent studies on metal oxide-based semiconductor gas sensors for formaldehyde gas detection, methods to improve the gas-sensing properties of metal oxides of various dimensions, and the effects of catalysts for the detection of parts-per-billion level gases. Through this, we discuss the necessary characteristics of the metal oxidebased semiconductors for gas sensors for the development of next-generation sensors.
