극한강우사상의 분석은 다양한 극치 분포로 구성된 극치이론을 통해 가능하다. 일반적으로 단일 지점의 극한사상의 분석을 위한 지점빈도해석 (Point Frequency Analysis, PFA)이 다양한 재현기간에 해당하는 강우량을 추정하는데 널리 사용되어왔다. 하지만 수문기후학적 극치기록은 시간적 그리고 공간적으로 제한적이다. 따라서 모의 불확실성을 줄이고 신뢰성 높은 결과를 도출하기 위해 서로 유사한 분포를 가질 수 있는 인근 지점의 활용하는 지역빈도해석 (Regional Frequency Analysis, RFA) 방법이 개발되어 적용되고 있다. 본 연구에서는 부산, 울산, 경남지역의 기상청 종관기상관측시스템(Automated Synoptic Observing System, ASOS) 울산, 부산, 통영, 진주, 거창, 합천, 밀양, 산청, 거제, 남해지점 일강수량을 자료를 기반으로 Metropolis-Hasting 알고리즘을 사용하여 일반극치분포(Generalized Extreme Value, GEV)의 매개변수를 추정하고 PFA 및 RFA의 불확실성을 평가하고자 한다. 이러한 연구는 공간적 구성 요소(예, 지리적 좌표, 고도)를 고려하지 못하며 추가변수 (예, 공변량)를 분석에 결합할 수 없는 등의 RFA의 한계를 극복하고, 명시적으로 불확실성을 추정하여 결과의 신뢰성을 확보 할 수 있는 계층적 베이지안 모델의 개발에 도움이 되리라 기대된다.

Archival description in archives has an important role in document control and reference service. Archives has made an effort to do archival description. But we have some differences and problems about a theory and practical processes comparing with advanced countries. The serious difference in a theory is that a function classification, maintenance of an original order, arrangement of multi-level description are not reflected in practical process. they are arranged in shelves after they are arranged by registration order in a unit of a volume like an arrangement of book. In addition, there are problems in history of agency change or control of index. So these can cause inconvenience for users. For improving, in this study we introduced the meaning and importance of arrangement of description, the situation and problem of arrangement of description in The National Archives, and a description guideline in other foreign countries. The next is an example for ISAD(G). This paper has chapter 8, the chapter 1 is introduction, the chapter 2 is the meaning and importance of arrangement of description, excluding the chapter 8 is conclusion we can say like this from the chapter 3 to the chapter 7. In the chapter 3, we explain GOVT we are using now and description element category in situation and problem of arrangement of description in Archives. In the chapter 4, this is about guideline from Archives in U.S.A, England and Australia. 1. Lifecycle Date Requirement Guide from NARA is introduced and of the description field, the way of the description about just one title element is introduced. 2. This is about the guideline of the description from Public Record Office. That name is National Archives Cataloguing Guidelines Introduction. We are saying "PROCAT" from this guideline and the seven procedure of description. 3. This is about Commomon Record Series from National Archives of Australia. we studied Registration & description procedures for CRS system. In the chapter 5, This is about the example which applied ISAD to. Archives introduce description of documents produced from Appeals Commission in the Ministry of Government Administration. In the chapter 6, 7. These are about the problems we pointed after using ISAD, naming for the document at procedure section in every institution, the lack of description fields category, the sort or classification of the kind or form, the reference or identified number, the absence description rule about the details, function classification, multi-level description, input format, arrangement of book shelf, authority control. The plan for improving are that problems. The best way for arrangement and description in Archives is to examine the standard, guideline, manual from archives in the advanced countries. So we suggested we need many research and study about this in the academic field.

This paper intends to identify the structure of homogeneous regions and functional regions in Seoul based on B.J.L. Berry's ‘general field theory of spatial behavior’. The structure of homogeneous regions by using socio-economic variables can explain how the structural elements of the city are arranged. It can be ssid that Seoul has shifted towards more complicated and differentiated features in terms of homogeneous regions. The different patterns are found between the northern part to Han River where old torn areas are located and the southern part to Han River where newly urbanized areas are located. Usually, the concentric pattern and the sectoral pattern coexist, which is enhanced moving from CBD to the outskirt area. The distribution of different social classes shows irregular pattern similar to the variation of living environment. The social gap is expected to be more widening between new towns and old towns. The analysis of spatial movement pattern shows no clear hierarchical order because of current shifts towards both multi-nuclear pattern and spatial dispersion. The functional regions show duplicated structure overlapping their boundaries each other. The ‘general field theory of spatial behavior’ strongly suggests that spatial interactions among sub-areas in the city are differentiated from the basic characteristics and function of each sub-area. The attributes of homogeneous regions and functional regions are interrelated in the characteristics of isomorphic nature.

The purpose of this study is to draw a systematic access method of career intervention for dance majors. This study conducted Delphi survey and Analytic Hierarchy Process(AHP). As a result of study, 16 elements of career intervention were produced in total 4 areas. Results show that vocational guidance puts emphasis on the understanding of the various vocations, career education on the career planning and goal, career counseling on the macro-narrative to the life and career intervention network on the dance job fair and workshop. In the complex weight of all factors, ratings of weight show that dance vocation guidance and career education are demanded significantly. Results show that expansion of career alternatives, application of diversified dance career development road map to the curriculum, development of test tool and outcome standard, dance educators' systematic career intervention education and systematization of network for career support were suggested as measures for dance career intervention. This study discussed about dynamic reality and systematic access method for dance majors based on theories of Holland(1997), Super(1990), and Savickas(2005).

This study aimed to build up the concept of culture welfare. For this purpose, we analyzed the practitioners' understanding about culture welfare in culture and social welfare by Modified Grounded Theory Approach. The results showed that the practitioners did not understand the concept of culture welfare clearly, and revealed being in confusion. Their understandings about culture welfare were classified into five types, 1) a type denying a terminology, culture welfare itself, 2) a type without awareness about culture welfare, 3) a type regarding culture welfare as sub realm in the special domain of culture and social welfare, 4) a type undividing and integrating culture and social welfare, 5) a type recognizing an independent domain of culture welfare. But despite of large deviation like this, the practitioners were common to give emphasis on giving opportunities to everyone in the enjoyment of culture, for heightening the quality of life. Summing up, culture welfare is defined as 'all direct and indirect effort in culture and arts, in a narrow sense to economical vulnerable class, and in a broad sense to everyone, to raise cultural susceptibility, creative thinking, and potential competence for realization a life worthy of man. The significance of this study is in establishment the definite and practical concept of culture welfare through a deep analysis the practitioners' understanding. This will give the theoretical basis to the study and the development of various programs in culture welfare.

Packages have been used for a wide variety of purposes, for protection, for display, for transportation of goods, or for keeping personal belongings. According to the demands of society and the times, liquor packages have been specialized and have appeared in almost every shape and size without restriction to cine particular type of material. In spite of its rapid development and wide application in our society, liquor package design has rarely been considered as a subject of comprehensive study. Majoring in package design, I have become especially interested in the area of liquor package design. I would like to explore liquor package design from several aspects. With the advent of new market and the rise of a new consumer society, advertising and mass media have expanded rapidly. While convenience of use is not a major issue, serving size certainly are quality, appeal of heritage and health concerns. Heritage is a major consumer appeal in Whisky, Beer, Wine and spirits. Designers have drawn heavily on the tradition of alcoholic products, have used type and graphics to create the illusion of heritage for new products. A sidelight to the heritage aspect of spirits package is the evolution of outer boxes for international liquors. International liquors package design illustrated the past and current themes. The design is contemporary and spare. Colored panels correlated to the liquor flavor used on clean white, black, gold boxes. While this research does not deny the impact of structural innovation and convenience package design , it does deny the existence of a graphic plateau. It is assumed therefore, that development in technology can facilitate communication between East and West. This can be accomplished because as containers of products are used in social setting, their form will gradually apply strong influence to the need for economical, easily handled, easily utilized packaging. Typically, ethnic package designs are those packages containing products which are prepared and marketed to a category of people who are prepared and marketed to a culture traits. They are liquor products sold in the metropolitan New York area which are marketed specially to Asians, Hispanics, or Eurpean population. These cultural groups share numerous traits including religion, language, dietary habits and traditional drinking styles. Therefore, the products which are familiar or common in their native countries are often imported or marketed there to serve them. These packages and products are frequently found on the shelves of supermarkets in predominantly ethnic areas. That is Korea, Japan if packaging is correctly design it would appeal to the American market. My research is that oriental beverage -Soju is good example of this precept. Assumedly, there must be a degree of subjectivity since it is a mean in which the consumers can relate to its advertising. This degree to relate and identify is the degree to which the package will be remembered and purchased. Subjectivity is intimately related to purchases since there is no such thing as a rational purchase in a society that operates on mass consumption. It is essential that packages become more personal human, entertaining, and more like advertising in order to maximize merchandising potential.

Under the premise that parks have been a performing field of welfare ideology that benefits the citizen from the past, the present study began with a basic question on what substance a park has and how it has worked. Therefore, this study tried to find out the theoretic background that can explain the roles of a park as an instrument for welfare, of which topic is currently being discussed, and examine how the ideology in the debate regarding welfare characteristics of parks are differentiated from those of social welfare. In addition, this study divided the process of development of parks defined by Galen Cranz in an attempt to view how welfare benefits offered by parks have changed in their development and looked into the roles and types of welfare functions that parks provided to the citizens under a certain social situation by period. Furthermore, the characteristics and development of the ideology underlying a welfare park were examined by function and element in its progression. The results of this study are as follows. The functions that parks have performed so far can be classified into three categories. First, they have a remedial function. Parks have given direct services to 'the socially disadvantaged' such as relief, fostering, and rehabilitation. Second, parks have played a preventive function. They aim to reinforce the functions of individual, family, group, and community. Third, they have exerted a developmental function. They function to promote change of society in a way for it to contribute to social development. Looking into the roles and functions of parks from the perspective of their beneficiary class and benefits, the following were discovered. First, the beneficiaries of welfare characteristics in parks have expanded to the general public from the poor class, and the benefits of parks have spread into the public including the underprivileged in a real sense. Second, the significance of welfare characteristics in parks has also changed from literal benefits to caring for basic human rights. Third, the purpose of welfare characteristics in parks has changed from providing minimal conditions to optimal conditions. At its beginning, the ideology of welfare in parks remained ideal, confining itself to their idealistic characteristics; but as time went on, they created several social benefits in response to various social demands, developing into a field where welfare ideology manifests and is realized in an active manner. Furthermore, it was witnessed that the parks and welfare of the present times are standing at the point of contact for participation and universal well-being. The present study reconsidered the meaning and value of parks from perspective of them as a provider of welfare benefits as well as examined how the welfare ideology of parks is connected to practice. By doing so, this study discovered the various roles, values, and ideology that parks should bear in the future. Therefore, this study is expected to be a good example for future research related to the topic.

The development in the mobile computing systems have arisen new and previously unforeseen problems, such as problems in information management of mobile host, disconnection of mobile host and low bandwidths of wireless communications. Especially, location information management strategy of mobile host results in an increased overhead in mobile computing systems. Due to the mobility of the mobiles host, the changes in the mobile host's address depends on the mobile host's location, and is maintained by mapping physical address on virtual address, Since previously suggested several strategies for mapping method between physical address and virtual address did not tackle the increase of mobile host and distribution of location information, it was not able to support the scalability in mobile computing systems. Thus, to distribute the location inrormation, we propose an advanced n-depth LiST (Location information Search Tree) and the parallel location search and update strategy based on the advanced n-depth LiST. The advanced n-depth LiST is logically a hierarchical structure that clusters the location information server by ring structure and reduces the location information search and update cost by parallel seatch and updated method. The experiment shows that even though the distance of two MHs that communicate with each other is large, due to the strnctural distribution of location information, advanced n-depth LiST results in good performance. Moreover, despite the reduction in the location information search cost, there was no increase in the location information update cost.

It's an important part to calculate the weights between criterions and to aggregate the decision inputs in a MCDM(Multi criterion decision making) This paper presents a method for aggregation cf decision inputs and application to the MCDM. We incorporate the fuzzy set theory and the basic nature of subjectivity due to ambiguity to achieve a flexible decision approach suitable for uncertain and fuzzy environments. To obtain the scoring that corresponds to the best alternative or the ranking of the alternatives, we need to use a total order for the fuzzy numbers involved in the problem. In this article, we consider a definition of such a total order, which is based on two subjective aspects: the degree of optimism/pessimism reflected with the ordered weighted averaging(OWA) oprators. A numerical example, expecially location analysis for anchorage area, is given to illustrate the approach.

The strength of particle-reinforced metal matrix composites is, in general, known to be increased by the geometrically necessary dislocations punched around a particle that form during cooling after consolidation because of coefficient of thermal expansion (CTE) mismatch between the particle and the matrix. An additional strength increase may also be observed, since another type of geometrically necessary dislocation can be formed during extensive deformation as a result of the strain gradient plasticity due to the elastic-plastic mismatch between the particle and the matrix. In this paper, the magnitudes of these two types of dislocations are calculated based on the dislocation plasticity. The dislocations are then converted to the respective strengths and allocated hierarchically to the matrix around the particle in the axisymmetric finite-element unit cell model. The proposed method is shown to be very effective by performing finite-element strength analysis of $SiC_p$/Al2124-T4 composites that included ductile failure in the matrix and particlematrix decohesion. The predicted results for different particle sizes and volume fractions show that the length scale effect of the particle size obviously affects the strength and failure behavior of the particle-reinforced metal matrix composites.
