The natural convection model of the consolidated system has been developed to make sure the removal of decay heat generated in the spent fuel for the loss of forced cooling accident. The numerical technique employed was based on the ADI scheme. The calculation of heat generation rate in the spent fuel was peformed by the ANS-79 decay heat model, and the nonuniform surface heat flux is assumed with a chopped sine curve for the conservative decay heat generation input. The sensitivity study was performed to examine the possibility of the pool bulk boiling by varying the various parameters, i.e. inter-fuel spacing ratio, heat generation power, and radius of the fuel rod. The application results of this model show that the natural circulation flow through compacted spent fuel bundles enables the pool temperature to control in a safe and effective manner, after the required cooling time. The corresponding acceptance criteria of the cooling time for rearranging the spent fuel rods were also found.

Objectives : It is sure that standardization of medical instruments is very important and necessary. Cupping therapy is one of the traditional oriental medical method, and it is necessary to set up a standard of cupping therapy and instruments. Methods : We select 3 major cupping instrument makers according to a questionnaire survey of 2001 oriental medical doctors. Dae Gun is A maker, Han Sol is B maker, Dong Bang is C maker. And with these air pumps we make experiments on stability by an inner impact test and a falling test. With these cups we check stability by an inner impact test and a disinfection test. And to know function of these instruments we test a negative pressure and maintain attached cups until 5 to 10minutes. Results : All results of experiments(impacted test, disinfection test, falling test) on stability of cups and air pumps are suitable for medical instrument. And the efficiency of 3 major makers shows various results. Negative pressure of B group is the highest, C group is the second, A group is the lowest. Pressure maintenance test shows A and C group is comparatively up to the experimental standard(<10%), B group is comparatively below the experimental standard(<10%). Conclusions : Results show stability of cups and air pumps is suitable for medical instruments. And negative pressure of cupping and maintenance of pressure show various results. So it is necessary to set up a standard negative pressure of cupping and maintenance of pressure.

Purpose : This study is a basic research to establish guidelines for healthcare facility in Korean healthcare market. As a first step, it is a main purpose for making beginning point of ICU guideline to set a basic level of ICU facility size and quality by analysis current ICU facilities and existed domestic guidelines : law, criteria of healthcare insurance review and assessment service, credit of Korea institute for healthcare accreditation. Methods : First of all, the all requirements of existed guidelines are put together and summarized. The summary is compared with that of US, UK, and Australia to know its quality difference with international market. In addition, all hospitals in Korean market are classified based on total bed number and ICU bed number to know the most occupied facility size range in the market. Second of all, by comparing 15 ICUs' current setting of the public general hospital, a general condition of ICU facility would be extracted based on function, floor area per bed, services Results : 72.8% of hospitals in Korea are belonging below 500 beds hospital. Among them 200-299 beds hospitals occupied 35.3% and are shown as the most occupied hospital size. As 15 public general hospitals are analyzed, it is clear that the more bed size and services the more ICU area per bed. As a result it is sure that the 300~500 bed may be a clear line as a general ICU condition whose function and bed number relatively consistent in the range. Implications : to keep the qualified medical environment and contemporary hospital trend, the guideline as a minimum requirement keep naturally out from current healthcare settings and should reflect their limit to reconcile with the new trend in the market.

The purpose of this study is to establish more rational and practical planning theory for amusementpark. It analyze and considerate the fluctuation of the people who come and use a Tong-Ch'on amusementpark. The results drawn from this research work are as follows ; There are considerable correlation between use fluctuation and some factors. The factors are season (spring, summer, autumn) as a time, temperature, cloud amount, duration of sunshine, weather (rainy day) as a climate and date (weekday, holiday) as a social system. The important variables are temperature, cloud amount, duration of sunshine and date (week day, holiday) to estimate the user of amusementpark. I can reduce the following two types of regression models. 1.${\log}_eY1=6.9114+0.1135TEM+0.00002_eSUM-0.4068WI+0.4316W3$ ($R^2=0.94$) 2. ${\log}_eY2=7.2069+0.1177TEM-0.0990CLO+0.488W3$ ($R^2=0.95$) Y ; Number of User TEM ; Temperature CLO ; Amount of cloud SUN ; Duration of Sunshine WI ; Weekday W3 ; Holiday Those model is inorder to estimate the user for management of Tong-Ch'on amusementpark and use on the computation of facility size for reconstruction. Besides the amusementpark, city park and outdoor recreation area could estimate of user throuth this method. But, I am not sure about the regression models because I didn't apply the regression models to the other amusementpark, city park or outdoor recreation area. Therefore, I think that this problem needs to study in the future.

The purpose of this study was to determine pH value of some alcoholic drinks sold in Korea and to provide the basic information which can cause dental erosion. Alcoholic drinks commercially sold were purchased from various big markets in Korea. The sorts of drinks tested in this study consisted of 5 brands of beers, 24 brands of makgeollis, 9 brands of wines and 12 brands of sojus. The test groups were selected randomly and the pH of each beverage was determined using a pH meter he each pH was measured. For statistical data, Mann-Whitney test was used to analyze difference for red wine and white wine and Kruskal-Wallis test was used to compare the pH of each test group. The result of this study was as followings: the mean pH of 5 brands of beers was 4.21, that of 24 brands of makgeollis 3.88, of 9 brands of wines 3.34 and of 12 brans of sojus 7.86. Each test group was significantly different (p<0.05). Except for soju groups, the test groups had a low pH value which can cause dental erosion. In terms of comparing between pH value of red wine and white wine, the result of this study represented that the mean pH of red wine was 3.45 and that of white wine was 3.21. This result showed the pH of two kinds of wine had a low pH which can lead to dental erosion and the difference of two wine were significantly different (p<0.05). As a result, some drinks sold in Korea have a high erosive potential on teeth since they have a comparatively low pH expect soju. Hence, when we consume some kinds of alcoholic drinks, we make sure to remember that the alcoholics which had a low pH, can have an effect on dental erosion that mean we should avoid to drink some alcoholic drinks with low pH for long time.

In the 'Society of the Spectacle', Guy Debord argued that modern life was dominated by the commodity form and the false desires it engendered. He predicted in 1967 that culture would become the driving force in the development of the economy by the end of the century, He was sure when culture becomes nothing more than a commodity, it must also become the star commodity of the spectacular society. Fashion, the starriest of star commodities with its seductive fantasy approaches to the viewers occluding the commercial reality. From this point, the spectacular property of the modern fashion can be found. This study starts on the notion that the modern fashion is on the center of capitalist consumer culture and is constructed by spectacle. On this premise, the purpose of this study is analysing the attribute of 'spectacle' and 'keeping distance ￡Tom spectacle' in modern fashion expressed in fashion show, fashion media and fashion store. The fashion houses in the 1990s that recognised the commercial value of shock and spectacle were eager to employ young spectacularly visible named designers. They generated the publicity necessary for sales of perfume, cosmetics, bags and diffusion range of clothes through the visible fashion show and fashion media. In the fashion show and fashion media, fashion goods as the commodity both flaunts and disguises its commercial nature in spectacle. The spectacle on the fashion store is the process turning the commodity into image to arouse viewer's higher interest. In the fashion store, the appearance of the commodity such as space, display, package is considered more importantly than its 'utility value'. Meanwhile, the study also covered the innovative trial to evade the ubiquitous 'spectacle' in fashion area.

Under the existing law, an act included in medical practice by medical personnel seems to be irrelevant to whether the act concerned in the "Life World" is in the category of medical practice. In spite of the act having been done according to the custom for a long time, and generally done by individuals in the "Life World", these kinds of acts have been banned by law, because if these acts were done by the general individuals, it would be considered as harmful behavior to human life and body. And it is not sure that individuals know such a ban or notification. This cause a "Mistake of Law". Also it is happened if someone knows the existence of law but believes that his/her act is not included. For treating the problem of "Mistake of Law" of unlicensed medical act, in this study I inquired thoroughly into the category and regulation of unlicensed medical act, uncertainty of the Medical Services Law the first Section of Article 27, the prohibition of unlicensed medical act. The "Composition Condition" of the first Section of Article 27 of the Medical Services Law is not certain, it doesn't meet the "Doctrine of Clearance", and it cause the "Mistake of Law". Also it doesn't meet standardization of constitutional state. An exceptional decision of Pusan District Court, the debate about unlicensed medical practice, constitutional decision on unlicensed medical practice of the Constitutional Court of Republic of Korea and point of view of support of regulation. Also I examined the problem of "Mistake of Law" that the regulation of unlicensed medical practice has. I tried to solve uncertainty of "Composition Condition" and proposed a direction of regulation for solving the "Mistake of Law" and the use of existing law.

Humanities knowledge makes the learners overcome the boundaries of study and can be applied variously by means of contents for study. This paper suggests application contents plans designed as the learning tools for blended learning, which can be sure of the possibility to the extension of other fields. Literary education with application contents has effects followings: First, smart device based on the web under the ubiquitous circumstances has the information system like the neuron's. So the application selects the necessary information and makes the contents for infusion into the education. Also it provides with more abundant and extended information system. With this approach, learners are able to get further literary knowledge and promote the ability for tapping them for new knowledge as well. Lastly, literature applied to the class with web contents is based on the foundation that creates new knowledge necessary for culture, arts, and so on. As a result, the education using web contents achieves the boundless of study, which is the final goal of the blended learning.

People believe donations are done by others who have the leisure time and money to do so. In addition, people distrust charity organizations because they aren't sure if the money is used properly which makes them hesitant to donate. In order to gain general public's trust and involvement, people need to start campaigning about trusting and donating to organizations. Looking into many different successful charity case studies, we can find how these different cases are attracting people and building their trust. Therefore, I propose the proper and effective ways to campaign for charity organizations through analyzing different case studies. The result shows that a campaign is most effective when arising amusement and curiosity in the general public. Also trust gets built in the minds of the public once the charity organizations became more transparent.

We are sure that Abakanowicz positively assumes a position of members, which are represented the later modern fabric design. In sprite of his pervasive evaluation, we have doubt about his achievement because the preceding research is insufficient about argumentsuch as dependence on intuitive emotion study, conventional analysis of structure and insufficient inquiry of causa efficiens. We agree that basic structure of is dissipation. Though right and left symmetrical structure is similar, also that structure is different. We can't decide whether structure is unification structure, difference structure or mixture structure . We think that the time of confusing argument of his structure is changing period for disorganization trend. The result of this study confirm the research possibility about space organization with restructure analysis and verification for examining essence structure of sample text . The Thesis are concern that the different between paradigmatic appearances and syntagmatic, which exist . So, we can approach the meaning of system and find dominent point about constructional relationship on the works. The meaning of dominent point is understood about sexless trend or Androgyne, which are appeared Abakanowicz forth work period. The relationship structure which is mixed both issue show that inner issue of work is located the highest position. The paper presents confusing manufacture system, which are suggested man-woman sex and mixed meaning. The other result of this study are, 1. being known as Abakan algorism, Abakanowicz has new drafting idiom from his ancient belief. 2. we need to research the body texture of Abakanowicz with the trend of restructure of body study. 3. we need argue about gender study in relative with poster moderntheology related problem of sexlessness people and perfect sex-people.
