Most of the Korean Diaspora who lived in Yunhaeju moved to Central Asia in 1937 following the deportation policy of Russia. The Korean Diaspora has maintained the traditional way of living for 140 years without a deep relationship with Korea. This study examined the dwellings of the Korean Diaspora of Kazakhstan in Central Asia through visiting their houses and conducting interviews. The results of the research were as follows. 1) The houses of the Korean Diaspora in Kazakhstan in early times consisted of Jungjigan which has Gudle and one bedroom. Gudle is the most traditional element of the Korean Diaspora's house and it is generally used as a place to gather family members. 2) The Korean Diaspora's houses in Kazakhstan were basically built according to Russian style but with a slightly different way of living inside. 3) The changing process of planning and building code of apartments in Kazakhstan is similar to that in Russia and other CIS nations. 4) Korean's food style is one mixed with Korean, Russian and Central Asian foods and Kimchi and Jang(bean paste) are the essential elements for most Koreans. 5) Koreans are very active to develop a relationship with Kazaks, Uighurs, and Russians and this enables the exchange of their culture eventually. This study is the first step to supply basic information for study of the Korean Diaspora in Central Asia and deeper research is necessary with a wide range in Russia.

Most of the Korean diaspora who lived in Yunhaeju moved to Central Asia in 1937 following the policy of deportation of Russia. Uzbekistan is the representative place for Korean diaspora to have settled down in Central Asia at that time and mort Korean diaspora in Central Asia are living in Uzbekistan now. Korean diaspora have maintained a traditional way of living for 140 years without a deep relationship with Korea. This study examined the dwellings of the Korean diaspora of Uzbekistan in Central Asia by visiting their houses and conducting interviews. Results of the research were as following: 1) The houses of the Korean diaspora in Uzbekistan in early times consisted of 2-3 bedrooms with Gudle. Gudle is the most traditional element of the Korean diaspora's house and it has been used as a place for gathering family members. 2) Korean diaspora's houses in Uzbekistan were built according to Russian and Uzbek style but most of the Korean diaspora's have a mixed style with traditional Korean elements of living.3) The changing process of planning and building codes of apartments in Uzbekistan is similar to that in other CIS nations and all of Russia. 4) Korean's food style is a mixture of Korean, Russian and Central Asian foods. Kimchi and Jang (bean paste) are essential for most Koreans and most Koreans are making these at home. 5) Most Koreans have maintained a good relationship with the Uzbek people and Koreans are very active in gelling along well with all. This enables them to exchange their culture eventually in various parts. This study could be the first step to supply basic information for the study of the Korean diaspora in Uzbekistan. Deeper research over a wider range is needed in Russia.

In order to analyze the effects of ground vibration caused by underground blasting having an effect on structure, the particle velocity and acceleration are calculated by using DYNPAK program. The DYNPAK program analyzes nonlinear transient dynamic problem and adopts the very popular and easily implemented, explicit, central difference scheme. In this program, the material behavior is assumed to be elasto-viscoplastic. Using the particle acceleration history, modal analysis method is applied to the forced vibration response of multiple-degree-of-freedom(MDOF) systems using unclupled equations of motion expressed in terms of the system's natural circular frequencies and modal damping factors. AS a means of evaluating the vibration behavior of building structure subjected to underground blasting, the time response of the displacements relative to the ground of five-story building is determined. It is concluded that the amount of explosives consumed per round, the location of structure, the properties of rock medium, the stiffness fo structure, etc. act on the important factors influencing on the safety of building and that the response of a structure subjected to a forced excitation can usually be obtained with reasonable accuracy by the modal analysis of only a few mode of the lower frequencies of the system.

In many parts of the world, low cost housing used to be built and maintained by the governments, based on designs and detail specifications prepared by the public sector with construction carried out by contractors. Results vary due to differences in design standards, workmanship and property management, depending also on the neighbourhood's care of the estates and their pattern of usage. In the UK, where Private Finance Initiative (PFI) has been used for infrastructure projects, there have been successful cases of city estate being transformed by PFI. These PFI housing schemes involve new-build, refurbishment as well as facility management. Unlike traditional construction, which is based on prescriptive specifications, PFI housing is based on output specifications. A study has been undertaken to compare the two specification approaches as they are applied to housing estate. Results are enlightening and serve as good reference to cities such as Hong Kong SAR and Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.

This study aimed to develop a design manual to be used during the initial stage of the nearly Zero Energy Building (nZEB) design process. Recently, with the increased demand for nZEBs, there are many architects and architectural firms who are becoming interested in nZEB design. However, since the nZEB design process requires a different approach to the conventional building design process, architects have difficulties with application of the nZEB design process in their projects. Therefore, a design manual which can be used in the nZEB design process was developed in this study. Based on an intensive literature review, energy-saving strategies and their performance levels, which affect heating and cooling energy consumptions were established for a reference building. To analyze the sensitivity of each energy strategy to the overall performance, computer simulations using EnergyPlus were performed. At the same time, an Analysis of Variance assessment was conducted to estimate the relative importance of each energy factor. The energy sensitivity and priority of the energy factors was developed into a set of design guidelines.

Recently, various building integrated wind power (BIWP) approaches have been used to produce energy by installing wind power generators in high-rise buildings constructed in urban areas. BIWP has advantages in that it does not require support to position the turbine up to the installation height, and the energy produced by the wind turbine can be applied directly to the building. The accurate evaluation of wind speed is important in urban wind power generation. In this study, a wind tunnel test and computational fluid dynamics (CFD) analysis were conducted to evaluate the wind speed for installing wind turbines between buildings. The analysis results showed that the longer the length of the buildings, which had the same height, the larger the wind speed between the two buildings. Furthermore, the narrower the building's width, the higher the wind velocity; these outcomes are due to the increase in the Venturi effect. In addition, the correlation coefficient between the results of the wind tunnel test and the CFD analysis was higher than 0.8, which is a very high value.

Paradigm depending only on fossil fuel for building heat source is rapidly changing. Accelerating the change, as it has been known, is obligation for reducing green house gas coming from use of fossil fuel, i.e. reaction to United Nations Framework Convention on Climate Change. In addition, factors such as high oil price, unstable supply, weapon of petroleum and oil peak, by replacing fossil fuel, contributes to advance of environmental friendly renewable energy which can be continuously reusable. Therefore, current new energy policies, beyond enhancing effectiveness of heat using equipments, are to make best efforts for national competitiveness. Our country supports 11 areas for new renewable energy including sun light, solar heat and wind power. Among those areas, ocean thermal energy specifies tidal power generation using tide of sea, wave and temperature differences, wave power generation and thermal power generation. But heat use of heat source from sea water itself has been excluded as non-utilized energy. In the future, sea water heat source which has not been used so far will be required to be specified as new renewable energy. This research is to survey local heating system in Europe using sea water, central solar heating plants, seasonal thermal energy store and to analyze large scale central solar heating plants in German. Seasonal thermal energy store necessarily need to be equipped with large scale thermal energy store. Currently operating central solar heating system is a effective method which significantly enhances sharing rate of solar heat in a way that stores excessive heat generating in summer and then replenish insufficient heat for winter. Construction cost for this system is primarily dependent on large scale seasonal heat store and this high priced heat store merely plays its role once per year. Since our country is faced with 3 directional sea, active research and development for using sea water heat as cooling and heating heat source is required for seashore villages and building units. This research suggests how to utilize new energy in a way that stores cooling heat of sea water into seasonal thermal energy store when temperature of sea water is its lowest temperature in February based on West Sea and then uses it as cooling heat source when cooling is necessary. Since this method utilizes seasonal thermal energy store from existing central solar heating plant for heating and cooling purpose respectively twice per year maximizing energy efficiency by achieving 2 seasonal thermal energy store, active research and development is necessarily required for the future.

우리나라에 공공도서관이 많이 없다. 그 이유는 국민들의 공공도서관에 대한 중요성 및 필요성에 대한 인식 부족과 중앙 및 지방정부의 도서관건립에 대한 인색한 투자와 함께 효과적인 공공도서관 건립정책이 없었기 때문이다. 이제 선진국과 같은 작은 도서관 건립 및 운영 정책을 펴야 한다. 지역 재개발 및 아파트 재건축 추진은 이들 지역에 작은 규모의 마을도서관을 건립할 수 있는 좋은 기회이다. 서울에 있는 J아파트는 재건축을 추진하고 있는데, 이 시점에서 새로운 위치로 옮겨가는 동사무소와 우체국을 하나의 건물로 신축하고, 이 건물 내에 공공도서관을 설치할 수 있을 것이다. 도서관을 이들 시설들과 함께 1층에 배치한다면 시너지 효과를 발생시켜 세 기관 모두에게 도움이 될 것이다. 이처럼 재개발 및 재건축 지역에 공공기관 혹은 상엽시설과 함께 복합건물 형태로 작은 도서관을 건립하는 것은 우리나라 공공도서관의 부족 문제를 해결 할 수 있는 좋은 방법이다.
