Recently, the space organization of Korean-Chinese houses is different from that of other territories. The vast land of China, coming from different hometown in Korean peninsula, and the different hometown in Korean peninsula, and the different procedure of settlement seem to make the different space organization of Chinese-Korean single family housing at the urban area in Liaoning Province.The characteristics of the Korean-Chinese space organization of single family housing at the urban area in Liaoning Province are as follows;i)Three types of space organization are central kitchen type, central corridors types, and central living room type. ii)The central kitchen type is mainly in old urban housing, after 1980's, the central corridor type appears in single family housing, and central living room type appears 1990's.iii) It seems that the main reason to change the space organization are fuel, system of heating, influence of Korea housing. Especially, Korean-Chinese like central living room type that is suitable for sit down living style. This central living room type supposes to be used as popular space organization in urban housing.

In this paper an experimental study is presented to investigate the dynamic behavior of impacting droplet onto a liquid film. The main parameters are the droplet velocity and the thickness of the liquid film. Photographic images are presented to show the formation of crown, central jet and disintegrating droplet from the central jet. The emphasis is on presenting the time evolution of crown diameter, crown height, central jet height and the size of disintegrating droplet from the central jet. The diameter and height of crown are higher for faster droplet and thinner liquid film. On the other hand, the height of central jet are higher for faster droplet and thicker liquid film. The size of disintegrating droplet from the central jet heavily depends on the droplet velocity; Larger droplet is produced with faster falling droplets.

Electronic cash affects central bank in many areas, in particular regarding the issuance of money, supervision of cashless payments, supervision of the banking system and monetary policy. The effects of electronic cash on central bank policies, the security and integrity of the payment system, and naturally also on single sector such as company engaged in the transport of money and valuables, depend mainly on the extent to which the new payment methods can replace cash. The possible development of electronic cash merits special attention from central banks for at least three reasons. First, central banks are concerned that the introduction of the new payment instrument should have no adverse effect on public confidence in the payment system and payment media. Second, although the substitution of electronic cash for other forms of money should not theoretically hamper central bank's ability to control the money supply, it might, however, have practial implications, at least in the long run, which need to be carefully examined. Third, because electronic cash may be used for payments of very small value, they have the potential, more than any other cashless instrument, to take over the role of notes and coins in the economy and, therefore, have implications for central bank's activities and revenues.

The purpose of this thesis is a searching out the characteristics of Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism and its influences on Korean modern dwellings especially in the time of 1930's. At the early stage of the colonial time($1905{\sim}1919$), the central corridor type Japanese dwellings were implanted into Korea for the Japanese official residences. The central corridor type Japanese dwelling was an urban modern dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. After the 1920's the central corridor type Japanese dwellings have spreaded itself and became a prototype of a modern dwelling in Korea. The characteristics of the central corridor type Japanese dwellings have influenced on the Korean high class dwellings and Korean architects' proposals for modern dwelling in the time of 1930's. By the implantation and spread of the central corridor type Japanese dwellings, Korean modern dwellings at the same time have affected and undergone transformation. The aspects of transformation were ; The outbreaking of the Japanese style entrance and central corridor, the transformation of MaDang from the inner court with a function of circulation into the outer court garden with plants and the transformation of Korean dwellings from the rural inner court type into the urban outer court type. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

Spent fuel is moved from the reactor into the spent fuel pool when nuclear power plant permanently shutdown. The sole function of a permanently defueled facility is to store spent fuel in a quiescent state. The function of electric system and loads are reduced. It is necessary to establish an operating strategy of electric system in the permanent shutdown nuclear plant. This paper reviews required loads and design criteria considering transition to permanent shutdown. An operating strategy of onsite electric system is proposed considering decommissioning strategy and stage of defueled condition.

The semi-discrete central scheme and central upwind scheme use Runge-Kutta (RK) time discretization. We do the Lax-Wendroff (LW) type time discretization for both schemes. We perform numerical experiments for various problems including two dimensional Riemann problems for Burgers' equation and Euler equations. The results show that the LW time discretization is more efficient in CPU time than the RK time discretization while maintaining the same order of accuracy.

The Central African Region is known as one of the most troubled and unsafe regions in Africa. But more recently the Central African Region has been growing and developing, with many projects underway involving huge local and foreign construction companies. Despite this fact, workers in the Central African Region often encounter unsafe working conditions and must confront many kinds of hazards. Therefore, the aim of this study is to identify the safety management situation in Central African construction sites, by focusing on the countries of Rwanda and DR Congo. Through our research, it was found that the two countries studied in the Central African Region are very similar with regard to their safety management systems, with some exceptions. In addition, it was revealed that both these countries in the Central African Region had good safety performance. This study will help to illuminate the situation of safety systems on construction sites in the Central African Region, and can be used by companies advancing into the Central African Region's construction market.

This study analyzed the dietary behaviors and adaptation for Korean foods among Central Asian workers(Mongolia, Kazakhstan, Uzbekistan, Kyrgyzstan) living in South Korea to provide basic and fundamental data that allows Central Asian workers to have desirable eating habits while living in South Korea. Questionnaires were completed by 186 Central Asian workers living in South Korea. From this study, we found that 56.8% of respondents ate three meals a day, and 27.2% of respondents ate two meals a day. 29.7% of respondents had no snacks. For adapting Korean food, Mongolia, Uzbekistan, Kyrgyzstan workers had difficulties adapting spicy and salty flavors and unpleasant smell while Kazakhstan workers had difficulties due to sweet flavors and spicy and salty flavors. Men adapted better than women to adapt Korean food. Women respondents ate Korean food more often than men. And the Uzbekistan ratio of eating homeland food daily was the highest. By providing understanding of dietary patterns of Central Asian workers, these results can be used as the basic and fundamental data for their Korean food adaptation.

In the calculation of DCGLs using RESRAD code, the selection of input parameter values is paramount, which is basically possible when specific measures for selecting reuse scenarios and probabilistic evaluation methods are established. When referring to the impact of the age group considered in the environmental impact assessment among the existing operations of the plant, it may also need to be applied in the decommissioning project, and there will be considerations along with site reuse scenarios and probabilistic evaluations. Therefore, the main purpose of this study is to distinguish the types of exposure affected by residual radioactivity contamination during the process of deriving DCGL to be used in the final site release stage of NPPs and to evaluate them by reasonably assigning age group parameter values. In addition, the case of entering a single value for parameter values by age group and the case of entering probabilistic distributions were compared and analyzed.
