According to the "Safety Evaluation Detailed Instructions (Dam)", precise safety inspection is carried out for dams that exceed a certain scale. However, as the Hydrological Safety Evaluation from various evaluation standards is designed to evaluate the safety of existing dams considering PMF, the evaluation is much less applicable for most agricultural reservoirs. Therefore, the Hydrological Safety Guidelines for agricultural reservoirs are expected to be re-evaluated considering the diverse risk factors with the coefficient model and AHP in this study. The coefficient model has been developed by selecting the hydrological safety superordinate subordinate evaluation factors to reflect diverse risk factors of agricultural reservoirs. After calculating the sum of indicators score for each evaluation factors, validation procedures were performed for the questionnaire which a panel answered. The practical coefficient has eventually been estimated for the hydrological safety evaluation considering the diverse risk factors. The conclusions acquired based on the study done are that both most agricultural reservoirs were classified as flood defense capability is insufficient and agricultural reservoirs which meet embankment-freeboard standards considering PMF was overestimated.

The purpose of this study was to develop a web-based internet program for nutritional assessment and diet management of patient having hyperlipidemia. Hyperlipidermia were classified by hypercholesterolemia and hypertriglyceridemia. The program consisted of four parts according to their functions and contents. The first part explained the metabolism of lipids and defined the hyperchotesterolemia and hypertriglyceridemia. The second part is to assess the general health status such as body weight, obesity index, basal metabolic rate and total energy requirement by the input of age, sex, height, weight and degree of activity. This part also provides the Patient with menus lists and 1 day menu suitable to his weight, activity and the status of hyperlipidemia and offers the information for food selection, snacks, convenience foods, dine-out, behavioral modification, cooking methods, food exchange lists, and information on energy and nutrients of foods and drinks, and top 20 foods classified by nutrients. The third part is designed to investigate diet history of patient, that is, to find out his inappropriate dietary habit and give him some suggestions for appropriate dietary behavior. This part also offers on-line counseling and frequently asked Questions. The fourth part is evaluating their energy and nutrients intake by comparing with recommended dietary allowance for Koreans or standardized data for patient with hyperlipidemia. In this part, it is also analyzing energy and nutrients of food consumed by food group and meals, and evaluating the status of nutrient intake. These results are finally displayed as tabular forms and graphical forms on the computer screen.

Female empowerment advertising campaigns are easily observed in the United States and European countries whereas it is rarely found in Korea. Thus, this study is designed to analyze female empowerment advertising campaigns so-called femvertising through a case analysis method. The case analysis is often employed in the field of advertising and other social sciences, especially is helpful in finding current trends. Study results found that themes of global femvertising campaigns could be categorized into 'redefining women's beauty', 'gender equality', 'education', and 'leadership'. The objective of these femvertising campaigns is to change perspectives of the society on women and change men's perspective. In terms of product category by global femvertising campaign companies, it varies from consumer goods, IT & electronics, automotive, finance, toy, non-profit organization to press. In general, femvertising targets women, but some femvertising campaigns also target men. This study also provides implications in regards with media usage strategy and advertising planning strategy.

Because web documents become creation and disappearance rapidly, users require the recommend system that offers users to browse the web document conveniently and correctly. One largely untapped source of knowledge about large data collections is contained in the cumulative experiences of individuals finding useful information in the collection. Recommendation systems attempt to extract such useful information by capturing and mining one or more measures of the usefulness of the data. The existing Information Filtering system has the shortcoming that it must have user's profile. And Collaborative Filtering system has the shortcoming that users have to rate each web document first and in high-quantity, low-quality environments, users may cover only a tiny percentage of documents available. And dynamic recommendation system using the user browsing pattern also provides users with unrelated web documents. This paper classifies these web documents using the similarity between the web documents under the web document type and extracts the user browsing sequential pattern DB using the users' session information based on the web server log file. When user approaches the web document, the proposed Dynamic recommendation system recommends Top N-associated web documents set that has high similarity between current web document and other web documents and recommends set that has sequential specificity using the extracted informations and users' session information.

A mobile device like ceil phone is the necessity of modern people, of ich con be easily connected to a wireless internet through such a mobile device. The demand for a wireless data communication is growing rapidly. However, agencies have not yet completed standardization of a markup language. Due to the development of the Mobile Device, agencies in this field have provided different data formats with each Mobile Device Platform. Traditionally, contents is hand-tailored to suit the target device. A key problem is that the characteristics and capabilities of the mobile device are too diverse to service the most suitable mobile contents. Because of these problems, the need for a re-usable document description language increases. In this paper, we defined Template file that is common data to service mobile devices. We proposed a method that could be an effective wireless web service though design and the implementation of the Call manager & the XSL Generator. In the methodology, when requesting a wireless internet service, a mobile device finds out markup language and a hardware specification of the mobile device through the Call Manager component supports. The XSL Generator component creates the XSL file dynamically that is the most suitable to a device. Finally, contents is serviced to each device by XSLT. It can generate a wireless page more easily by reusing the existing web contents through such course. Therefore, it can save the time and expense for generating a wireless page.

Using methods of principle component analysis and pattern of analysis. Korean food supply pattern and its change (1962-1969) have been compared whit those of other 40 countries. 1) Among the 4 groups classified on the first and second principle components, Korea belongs to the highest crop grain dependent group of Asia. Although Korea is identified as one of the highest crop consuming countries among the group, a significant increase in the consumption of fruits and vegetables is noticed during the period. 2) According to the pattern of numerics analysis Korean food supply pattern (1969) is similar with those of Japan (1949), philippines, Taiwan, while is quite apart from those of U.S.A., W. Germany, France and Australia. 3) During the period the food supply pattern of Korea has been changed significantly toward the more common locations on the world food supply pattern map. Yet the location is far from the desirable one and its moving direction is characteristic, differing not only those of Europian countries but also Asian neighborhoods. this unique pattern should receive a careful examination and thus proper measures should be undertaken to take care of optimal nation's nutritional requirements.

Today, it is necessary to calculate orbits with high accuracy in space flight. The key words of Poincar$\acute{e}$ in celestial mechanics are periodic solutions, invariant integrals, asymptotic solutions, characteristic exponents and the non existence of new single-valued integrals. Poincar$\acute{e}$ define an invariant integral of the system as the form which maintains a constant value at all time $t$, where the integration is taken over the arc of a curve and $Y_i$ are some functions of $x$, and extend 2 dimension and 3 dimension. Eigenvalues are classified as the form of trajectories, as corresponding to nodes, foci, saddle points and center. In periodic solutions, the stability of periodic solutions is dependent on the properties of their characteristic exponents. Poincar$\acute{e}$ called bifurcation that is the possibility of existence of chaotic orbit in planetary motion. Existence of near exceptional trajectories as Hadamard's accounts, says that there are probabilistic orbits. In this context we study the eigenvalue problem in early 20th century in three body problem by analyzing the works of Darwin, Bruns, Gyld$\acute{e}$n, Sundman, Hill, Lyapunov, Birkhoff, Painlev$\acute{e}$ and Hadamard.

The kitsch was emerged from the people's cultural desire in the conditions of the various duplicating technology, the capital economy system, and the civil revolution in the western modern mass society. But it is underestimated constantly because of the conspicious consumption and the aesthetic inadequacy. Even though some kitsches are elevated to the 'kitsch arts' in the historical description of the modern arts, still the most of kitsches are remained as 'just kitsches' and excluded from the aesthetic research according to the double standard. In this essay, I research for whether anti-kitsch theory is convincing theoretically and practically. Anti-kitsch theory criticizes the kitsch on the basis of the modernist aesthetics, in which the 'fine art' provokes the aesthetic pleasure in the disinterested contemplation. But kitsch purposes for the sensual gratification and the sentimentality. So the anti-kitish theorists conclude that the kitsch is the bad taste. In critically analyzing the argumentation of Greenberg's. Kaplan's and $C{\tilde{a}}linescu^{\prime}s$, I refute the privileged prejudice of the ideal critic. They don't justify the criteria of the classification of 'art'/ 'kitsch'. They supplement the economical and the political grounds for the evaluative theory of the kitsch. But the argumentation of the kitsch is consumed conspicuously and results in the unlettered masses is not sufficient. People produce and enjoy the kitsches in the various ways. People envelope the genres, styles and media of the kitsches and they try to suggest the new horizon of the popular aesthetics. So anti-kitsch theories cannot be accepted because they adhere to the elitism and formalism. The exclusion of the kitsch is the derogation for people's taste. Also they didn't reflect the contemporary cultural practice and the aesthetic needs in the system of post-art. The alternative aesthetics of the kitsch is the topic of my next essay.

The slippery slope argument means that if we accept a type of action A, we are committed to accepting B, C and eventually N. Then, N is situation which we must not accept morally. It works causal mechnism that B because A is raised, C because B is raised. But in the logic textbooks and treatises, the slippery slope argument is classified as fallacy. The reason is that the argument is not a causal argument. Actually, it is a probable. Also it is argued that the argument is wrong because it fears about the future extremely. But We can not say all slippery slope argument is fallacy even though a slippery slope argument is sometimes fallacy. I think it is persuasive argument in a significant place. Therefore I argue that the argument is not simple logic as a form of thinking, but practical reasoning applied the context of dialogue. So in order to find it to be practical reasoning we demand the new understanding to fallacy theory. In traditionally, fallacy is defined to wrong reasoning logically, but according to Walton, fallacy means a verbal tactic or deceptive trick that can be used to cause someone to fall down in argument. That is to say, whether or not the argument is successful depends on how it uses as argument tactic in a given context of dialogue. Therefore I argue that whether or not the argument is successful, because of it is practical problem used in a context of dialogue, is to be approached to pragma and dialectical method, not semantic.

In Cheongsong area, very rare spherulitic rhyolites both in Korea and foreign countries occur as dykes showing various types. The spherulites in them represent an undercooling caused by very fast cooling of the dykes in a shallow depth near to the surface and the variety of types were resulted from the difference of relative cooling rate. Cheongsong spherulitic rhyolites can be classified into five types; radiated simple spherulite, layered simple spherulite, layered multiple spherulite, radiated-layered multiple spherulite, radiating layered multiple spherulite. Radiated simple and radiating layered multiple spherulites formed by diffusion current caused by undercooling related to very fast cooling. On the other hand, layered multiple spherulites formed by relatively slow diffusion as a Liesegang ring during relatively slow cooling. If the cooling rate is between the two cases, layered simple spherulites formed. This interpretation indicates that Chrysanthemum, Dandelion, Dahlia and Sunflower types which are included in radiated simple or radiating layered multiple spherulites formed in the dykes with the fastest cooling rate in Cheongsong area while Peony, Rose and Innominate types classified as layered multiple spherulite formed in the dykes with the relatively slowest cooling rate. At the cooling rate between them, Apricot type spherulite formed. The K-Ar age-dating for Cheongsong spherulitic rhyolites indicate them to be formed between 48 and 50 Ma. The Cheongsong rhyolites are very valuable for research and preservation because of their rarity, beauty and diversity.
