Prior to the service evaluation, many kinds of its attributes must be identified on the basis of rational decision owing to complexity and ambiguity inherent in logistics service. there are so many evaluation methods but they are not applicable to logistics service the have property of non-additivity and overlapped attributes. Therefore, probability measure can not used to evaluate logistics service but Fuzzy Measure is required. And the method should be easy to calculate it Recently Fuzzy theory has been applied in Various evaluation problem. Fuzzy evaluation based on Fuzzy theory can accommodate fuzziness in judgement with people through introducing Fuzzy Measure. In this paper, Hierarchical Fuzzy Process is applied to evaluate level of logistics service in Korail and the biggest six logistics companies in the korea which is called 3PL Company. Also Fuzzy Relation Equation which is problem identifying evaluation value at these fuzzy evaluation is applied to verify relation between Input and Output data through @-operation. Therefore, we apply this Fuzzy Relation Equation to Hierarchical Fuzzy Process and verify evaluation value which objects of evaluation are able to possess.

Hierarchical clustering methods have been proposed for more than sixty years and yet are used in various disciplines for relation observation and clustering purposes. In 1965, divisive hierarchical methods were proposed in biological sciences and have been used in various disciplines such as, and anthropology, ecology. Furthermore, recently hierarchical methods are being deployed in economy and energy studies. Unlike most clustering algorithms that require the number of clusters to be specified by the user, hierarchical clustering is well suited for situations where the number of clusters is unknown. This paper presents an overview of the hierarchical clustering algorithm. The dissimilarity measurements that can be utilized in hierarchical clustering algorithms are discussed. Further, the paper highlights the various and recent disciplines where the hierarchical clustering algorithms are employed.

The purpose of this paper is to examine the analytic-assembling(faceted analysis) methods applied in enumerative-hierarchical classification schemes. (mainly in KDC) The methods are summarized as follows : 1. For the enumerative-hierarchical classification schemes, in principle the subjects are divided into subdivisions by only one facet at the same level, and step by step. However some subjects, for example 'library and information science' 'education' and others in KDC, are divided into subdivisions by multiple facets at same level like Colon Classification. 2. Most of enumerative-hierarchical classification schemes have various kinds of auxiliary tables, such as standard subdivisions, areas, periods, and languages. Each of them is considered as foci by a facet applied to subdivide all kinds of subjects or some special subjects into lower level. 3. To classify the compound subjects with phase relation, KDC provides ready-made classification numbers or notes that says 'divide by 001-999'(whole subjects) of 'divide by xxx-xxx'(limited scope of subjects). The ready-made compound subjects, or subdividing by whole or limited scope of subjects are similar to representation of phase relation in Colon Classification. Yet these analytic-assembling methods in KDC are needed to be supplemented and amended. Subdividing methods for faceted analysis have to be unified through the whole schedule. The auxiliary tables should be enlarged and subdivided more specifically. And for representation of phase relation, the linking signs can be useful in KDC as well as UDC and other analytic-assembling classification schemes like Colon Classification.

This article studies that Korean literature has been renewed to World literature-oriented in the history of Modern Korean literary criticism from early modern period to present for reflecting the slogan, "globalization of Korean Literature" as well as contextualizing the necessity, "new relationship between Korean literature and World literature". Some writers, such as Lee Gwangsoo a pioneer of Modern Korean literature and the group for foreign literature[haioei-munhak-pa] introducing World literature to Korea and Lim hwa a prominent critic of proletarian literary theory under Japanese Colonial period, have understood European literature as World literature Korean literature had to reach. Inevitably the hierarchical relation between Korean literature and European literature as World literature had been interiorized to them. Meanwhile Jo Dong-il and Paik Nak-chung who have been representative researchers of Korean literature had tried to broken down the hierarchical relation between Korean literature and European literature interiorized to Korean writers until the 1980s, with Korean literature could be accomplished to World literature meaning. Since the late 1990s Park Sung-chang and Park Sang-jin who are leading researchers of comparative literature in Korea these days, have emphasized the methodology of new comparative literature for 'universality of literature' between Korean literature and World literature, which have been the renewal way of Korean literature in today's age of globalization.

This paper presents an analytical technique for reliability evaluation of electrical distribution network (EDN) containing distributed generation (DG). Based on hierarchical levels of circuit breaker controlling zones and feeder sections, a directed-relation-graph (DRG) for an END is formed to describe the hierarchical structure of the EDN. The reliability indices of EDN and load points can be evaluated directly using the formed DRG, and the reliability evaluation of an EDN containing DGs can also be done without re-forming the DRG. The proposed technique incorporates multi-state models of photovoltaic and diesel generations, as well as weather factors. The IEEE-RBTS Bus 6 EDN is used to validate the proposed technique; and a practical campus EDN containing DG was also analyzed using the proposed technique.

This study examined the moderating role of teacher-child relationship on the relation between children's problem behavior and peer victimization. Participants were 198 children(97 boys, 101 girls; recruited from classes with 5-6 year olds) and their kindergarten teachers. The teachers completed the rating scales to measure the children's peer victimization, problem behavior and teacher-child relationship. The collected data were analyzed using descriptive statistics, t-tests, correlations, and hierarchical multiple regressions. Boys and girls were analyzed separately. Results showed that children's problem behavior had positive relation to their peer victimization. Teacher-child relationship significantly related to children's peer victimization. Hierarchical regression analysis indicated that the interaction of boys' withdrawal behavior and teacher-child closeness predicted boy's peer victimization. Boys' withdrawal behavior, whose teachers demonstrated the lowest level of teacher-child closeness, associated significantly with their peer victimization. Boys' withdrawal and aggressive behavior had significant relation to their peer victimization, especially for the highest level of teacher-child conflictual relationship. Findings suggested the importance of teacher-child relationship in the context of intervention planning for peer victimization.

인터넷상에는 다양한 정보 자원들이 존재하고 있으며 최근에는 XML에 대한 관심이 날로 증가하고 있다. XML은 정보의 구조를 자유롭게 정의할 수 있기 때문에 동일한 응용영역을 표현하는 문서들은 상호 이질적이므로 문서들의 특성에 맞는 각각의 응용프로그램이 필요하다. 만일, 특정 정보를 표현하는 XML문서에 적용되는 DTD가 개념정보를 포함하고 있다면 문서의 구조에 자유롭게 적용될 수 있으므로 상호 이질적인 문제를 극복할 수 있다. 본 연구에서는 개념정보가 포함된 포괄적 DTD를 자동으로 생성하기 위하여 DTD생성기를 개발하였다. 또한 응용영역을 개념화하여 포괄적 DTD를 생성하는데 사용하였다. 포괄적 DTD는 개념정보를 포함하고 있으므로 동일 응용영역 표현하는 다른 구조의 XML 문서에 모두 적용될 수 있으며, 문서의 유효성을 검증하고, 유연한 응용프로그램의 접근이 가능하게 하였다.

Hierarchical galaxy formation models under LCDM cosmology predict that the most massive structures such as galaxy clusters (M > $10^{14}M_{\odot}$) appear late (z < 1) in the history of the universe through hierarchical clustering of small objects. Galaxy formation is also expected to be accelerated in overdense environments, with the star formation rate-density relation to be established at z ~ 2. In this talk, we present our search of massive structures of galaxies at 0.7 < z < 4, using the data from GOODS survey and our own imaging survey, Infrared Medium-deep Survey (IMS). From these studies, we find that there are excess of massive structures of galaxies at z > 2 in comparison to the Millennium simulation data. At 1 < z < 2, the number density of massive structures is consistent with the simulation data, but the star formation history is more or less identical between field and cluster. The star formation quenching process is dominated by internal process (stellar mass). The environmental effect becomes important only at z < 1, which contributes to create the well known star formation-density relation in the local universe. Our results suggest that galaxy formation models under LCDM cosmology may require further refinements to match the observation.

In conventional probability-based quality evaluation of products with qualitative characteristics, many factors that affect the evaluation are not easily represented quantitatively, because the relation between reliability of human evaluator and each of these factors is not clear. In order to evaluate the quality of product with qualitative characteristics quantitatively, in this paper, the relation is represented as the shape of possibility distribution function of fuzzy set on the interval [0,1]. Furthermore, fuzzy reasoning is used to obtain the estimates of quality characteristics. And, it is supposed that many quality characteristics affected by the above factors are connected with the final characteristic through hierarchical structures. Finally, using the estimates gained from the final evaluation, qualitative characteristics are evaluated by use of concept of pattern recognition.
