The HANARO, multi-purpose research reactor, 30 MWth open-tank-in-pool type, is under 24 MWth of power operation since it reached to the initial critical in February, 1995. Many useful experiments should be safely performed to activate the utilization of the HANARO, but there is a radioactive risk of using the HANARO. To reduce the risk, a test facility, which is not reacted by nuclear fuel, is being developed to simulate similar flow characteristics with the HANARO. This paper describes the computational flow analysis to determine each shape of simulating fuels for simulating the flow similarities of 36 elements hexagonal fuels assembly and 18 elements circulating fuels assembly loaded in HANARO. The shares of orifices were determined by the trial and error method and the structural integrities of them were verified by the finite element method assuming that the flow rate and pressure differences of reactor core are constant. The analysis results will be verified with the results of the flow test to be performed after the installation of this test facility.

At this point in time South Korea is rapidly metastasizing to a aging society. A major cause of aging can be summarized as increased life expectancy, decrease of nuclear family and birthrate, and South Korea's progress is faster than any other country. From the 1970s, western society has changed social welfare to deinstitutionalization and community care because of problems about economic reason and facilities protection, so the type of elderly social service has also changed from the facility welfare service which is accommodated old people in certain facility to community welfare service which provides various welfare services with living together. Public facilities for low income group which are supported by government are lower, 6.6%, than the United States or Japan, 50%. They are divided into private manage facilities and subscription elderly facilities. These subscription elderly residential facilities show poor administration because of focusing on development and market analysis for investment returns. Therefore, in order to vitalize the elderly welfare residential facilities in Korea, we need plans about systematic services facilities for welfare and phased medical treatments. Therefore, the purpose of this study is that (1) the types and functions of residents for community elderly residential facilities in elderly welfare policies of U.S., and supported policies are researched as a transcendental model, (2) data about operating system with the principles of the market is analyzed, and (3) basic data about welfare facility plan for community residential elderly people is provided.

The atmosphere of foodservice facility is considered to be the total environment to which customers are exposed. Atmosphere is sometimes described as everything that makes an impression on people. On the other hand, mood is best described as the response of an individual to the various components that make up the atmosphere. Most people experience some type of reaction to the atmosphere that may be desirable or undesirable. If the individual response to the foofservice facility is favorable, the atmosphere has served to put that person into a good mood. In the highly competitive commercial restaurant field, the planning of the atmosphere for new facilities is going to be more important. The coming generation of potential customers is growing up in an environment that associates dining out with more than just good food. This study is characterized by the right atmosphere offerings. Thus, this study discusses the physical components affecting perception of atmosphere. Many of these components will be discussed in detail to show their relationship to the design of dining areas. This study identified the many physical components of atmosphere that can be manipulated and arrive at a combination that will give the desired sensations. With these backgrounds as a guide, this study presented alternatives which should not only provide atmosphere but should reach a satisfactory level of creating atmosphere from a practical standpoint. these is to maximise the perceptual effect, train the employees, and be reflected and be reflected the advertising and public relations.

This paper considers a two-stage supply system consisting of two make-to-stock facilities. The facility in the first stage produces a single type of component in anticipation of future demands from the market and the end item production while the facility in the second stage produces the end item in anticipation of future demands from the OEM customers. The facility in the first stage has the option of to accept or reject each incoming demand from the market. In this paper, we address the problem of how to control the exogenous component demand and how to manage the production of the end item and the component so as to maximize the system's profit subject to the system costs. In this paper, we present a heuristic policy that is the base-stock production policy combined with a linear switching curve for component demand control. Numerical study is implemented under different operating conditions of the system and it shows that the performance of the heuristic is very promising compared to that of the optimal policy for the Markov model.

The purpose of this study is to identify if dental patients discriminate between dental clinic and dental hospital and the related factors for choice of dental facilities. A self-administered questionnaire survey was conducted from March 21 to April 11, 2011. Among 430 dental patients who visited dental clinic or dental hospital twice or more in Daegu, 410 dental patients were included in analysis. A total of 73.6% of the dental clinic visitors recognized correctly that the visiting facility was dental clinic and 82.3% of dental hospital visitors did correctly. Therefore, it can be said that dental hospital visitors recognize better the type of dental care facilities they visit. When it comes to choosing the dental facility, there were not much differences between the clinic and hospital patients in this study. Human resources, facilities and equipment, service are factors for choosing dental clinic and dental hospital in order. However, modern dental facility and equipment were more important factor for patients to choose dental hospital than clinic. It will be necessary for dental clinic or dental hospital to develop its own specific service to fulfill dental patients' needs through further studies on factors for choosing dental facilities.

Currently the forest area is 6,370,000 hectare (ha) which occupies 63.7% in Korea. The forest has good functions such as production of forest products, conservation of national land, prevention of disasters, etc. However constructing houses near the forest area make bad situation like illegal waste incineration by resident. So research subject is forest fire caused by waste incineration place including facility. And this study was conducted about statistical analysis and research analysis of the 100 waste incineration places including facilities at the country town. Statistical analysis shows that March is 27% which percentage is the highest number of forest fire in 10 years' average. The number of forest fire caused by waste incineration is 45 which is the third highest number in the fire statistic. The distance between waste incineration place including facility and forest area is 30m, 40m and 50m. That 40m (36%) is the most common distance from forest area. The types of waste incineration are ground (62%), the temporary facility made with oil drum can (35%) and other made with steel sheet, concrete, etc. The result of this study is that government and local government must conduct the improvement measure to reduce illegal incineration such as waste pickup area made with rain and wind proof type installed near residence, expenses for waste treatment, enlightenment and training, etc. Also considering their age and income are needed for realistic improvement.

Eco-friendly and sustainable seaweed biomass energy have been under the spotlight as the future of renewable energy. However, seaweed culture is primarily conducted inshore, with the research on offshore culture still in an early stage. For massive biomass production, a systematic engineering approach is required to devise offshore seaweed culture facilities rather than the conventional empirical ones. To establish the fundamental behavior of seaweed culture facilities, the dynamic characteristics of a seaweed culture facility were analyzed in the study. For this purpose, numerical analyses of the seaweed culture facility (a frame type) were carried out by using the hydrodynamic simulation program ANSYS-AQWA. For the analysis, environmental loads were considered using the wave spectra and co-linear current; mooring variables were selected as parameters; and time domain analyses were carried out to acquire the time series responses and eventually the dynamic characteristics. Finally, the mooring performance was evaluated. It was found that the motion could be controlled by adjusting the buoyancy and mooring slope.

Cloud BIM, which incorporates cloud computing technology and BIM technology, is increasingly used in construction. In particular, the recent trend of cloud services in IT field is to provide customized cloud services according to the characteristics of users. These changes are also linked to the cloud BIM, which is emerging in the construction industry. However, cloud BIM researches and commercial technologies that are currently underway do not reflect these trends, and they provide services through generalized management functions in construction projects. In order to solve these problems, a new type of customized cloud BIM service is needed that can provide cloud services by reflecting the characteristics of the project, customization based on the user's work, and providing the knowledge service. Therefore, this study aims to derive the system requirement function that should be preceded for implementing the customized cloud BIM service, and the target project is selected as the medical facility.
