This work focuses on current sharing between punch-through insulated gate bipolar transistors (IGBTs) connected in parallel and evaluates the mechanisms that allow overall current balancing. Two different control strategies are presented. These strategies are based on the modification of transistor gate-emitter control voltage V_GE by using an active gate driver circuit. The first strategy relies on the calculation of the average value of the current flowing through all parallel-connected IGBTs. The second strategy is proposed by the authors on the basis of a current cross reference control scheme. Finally, the simulation and experimental results of the application of the two current sharing control algorithms are presented.

From women's magazine published between January to June in 2002. Ywo page spread magazine advertising were selected for this study. From the findings, standard layout of two page spread advertisements in women's magazine Language are enumerated. It is written in Korean or Korean and English in black roman/serifs or square typeface for headline copy written in same typeface. Two to three color are used for typeface in the most ads. The relationship between product life cycle and all research items shows that there is very strong relationship.

Visual and color in Korean newspaper advertisements appeared in transformational advertising (21cm$\times$30.4cm) were analyzed. Data were gathered from 191 advertisements shown on major four daily newspaper; Dong-a, Joong-ang, Chosun, and Hanguk from October to December in 2000. From the results of this research, researcher concluded the followings; Both Korean and English are frequently used. With expectation of high readability, Roman/serifs and San serifs are mostly used typefaces. Selecting color for copy and backgraund in advertisements became more varied to satisfy varied consumers' personality.

1. In the late second century A.D. the dalmatic, which originated in Orient, came into fashion in the Roman world. 2. It was first introduced as a vestment in public worship by Pope Sylvester I (314-335A.D.) who ordered it to be worn by the deacons. 3. The dalmatic was cut like a tunic, but wider, and with wide short sleeves. It was worn without belt, and was characteristically decorated by the clavus. Its shape, which is the form of a cross, refer to the passion of Christ. It symbolizes joy, salvation and justice. 4. In early christian epoch, colors was found in the Bible. 5. Clavus running from the shoulders to the hem in front and back represented as 'The servant of God', and symbolized the Blood of Christ. With time, clavi change from simple stripes to decorative ones.

Apart from its Greco-Roman and Christian connotations, considering its continuous influence in the Byzantine world, the oikoumene should be seen as a geo-political as well as socio-religious concept of networking and unity in popular thought and local narratives. This paper argues that "ecumenical" thought survived after Late Antiquity and through the Byzantine era in the Orthodox transportation infrastructure of people and information. It also provides a review of the circulation of heresiological "labels" in the middle to late Byzantine eras. In the Mediterranean, routes, transportation vehicles, and any media supported intelligent networking in the oikoumene. People in the oikoumene could access foreign teachings or stories from outsiders or "barbarians" of different faiths. Constantinopolitan intellectuals coined and issued labels for heretics, such as the Bogomils, Paulicians, and Massalians, and constructed a narrative of the heretical contamination from the center of the oikoumene. Heresiologists collected the information used in creating these heresy titles from far-flung places in all directions from Constantinople, and then exported the labels, which were spread using the transportation network of the Byzantine oikoumene.

This paper attempts to demonstrate how the linguistic and mythological features of the shamanic language make it incantatory, or ′enchanting′. Passages used in shamanic rites manifest linguistic characteristics that point to their own norms and conventions, as well as some mythological features that contribute to the undecipherablity of the shamanic language. Focusing on the estranged linguistic and mythological features, I propose that shamanic languages can be best interpreted in terms of the linguistic hierarchization, a notion that has been developed since Roman Jakobson′s poetics. The present study adopts Eisele′s framework that reinterprets Jakobsonian hierarchization into a slightly revised notion on the basis of the "degree of combinatorial freedom" and the "degree of semantic immediacy", looking into a set of paradigm examples in search of some parallel structures characterizing the shamanic language. The enchanting effect of this peculiar form of language, it is argued, is due mostly to the frequent use of lexical parallelism, which works in the reverse direction of the normal process of interpretation.

The purpose of this study is to analyze the multi-layered space utilized as strategy for deconstruction in the architecture of Hiromi Fujii. Although the design of Eisenman and Fujii was based on the philosophical theory of Jacques Derrida, there are many different aspects of architecture. At the same time, Hiromi Fujii could construct his concept of multi-layered space to colligate the academic knowledge of Jacques Derrida, Roman Jakobson and Colin Rowe. This kind of concept for multi-layered space is a critical element to be distinct from the characters between two architects, and it is implied such as an significant concept to analyze the architecture for Hiromi Fujii. This multi-layered space contains interesting and researchable value to understand and to analyze the western architecture theory from the viewpoint of Asian architect. Accordingly, the purpose of the thesis is to find the meaning to establish an theoretical foundation for being under discussion to the architecture of Fujii through the concept of multi-layered space.

본 논문은 한글 고유 명사를 새로 개정된 한글 로마자 표기법에 의해 로마자 표기로 변환하는 시스템의 구성에 대해 기술하였다. 1995년에 문화체육부에서 배포한 프로그램 이후로 현재까지 한글을 로마자 표기로 자동 변환하는 프로그램이 나오지 않았고 이 프로그램 또한 새로 개정된 로마자 표기법이 아닌 예전의 로마자 표기법을 따르는 이유로 본 논문은 새로 개정된 표기법을 따르는 한글 고유명사의 로마자 자동 변환 시스템을 DB를 이용하여 구축하는 방안을 제시하였다. 그 결과 DB를 이용한 한글의 로마자 자동변환시스템은 개발자 측면에서는 프로그램 구현과 정확성 면에서 효과적인 장점을 얻을 수 있으며, 사용자 측면에서는 새로 개정된 개정안을 쉽게 익히고, 사용할 수 있게 한다.

Humans have a long history of asbestos use. There are reports from the Roman era, of asbestos victims among the slaves who worked in asbestos mines. The fact that asbestos can induce lung cancer and mesothelioma was verified epidemiologically in the 1960s. Asbestos related diseases are predominantly occupational in nature but can be caused by environmental exposure. Environmental mesothelioma is mainly associated with tremolite asbestos and this information comes from many countries including Turkey, Greece, Corsica, New Caledonia and Cyprus. In 1993, the first case of mesothelioma in Korea was reported in an asbestos textile worker. Recently, some asbestos disease victims who lived near an asbestos factory have their cases before the courts. A series of recent asbestos-related events in Korea, for example, the shocking revelation of asbestos containing talc in baby powders have caused the general public to become aware of the health risks of asbestos exposure. Asbestos related diseases are characterized by a long latency period, especially, mesothelioma which has no threshold of safety. Hence the best strategy for preventing asbestos related diseases is to decrease asbestos exposure levels to as low as possible.
