김상기,황병곤 대구대학교 2005 대구대학교 학술논문집 Vol.1 No.1

본 논문에서는 무선 인터넷 플랫폼에 관해 고찰하고 한국형 무선 인터넷 플랫폼 표준인 WIPI를 이용하여 DQQ(Daegu University Quiz Quiz)라는 모바일 게임 컨텐츠를 제작하였다. 이 DQQ는 Java 언어 기반의 플랫폼에서 Jlet을 사용하여 제작 되었고, 학교 실제 지도와 실제 건물 사진을 제공하여 사실성을 높였다. 또한 네트워크 게임 기능을 구현하여 커뮤니케이션을 하면서 서로간 게임을 할 수 있다. 한편 이 DQQ는 신입생, 재학생 및 편입생을 대상으로 학교 소개 및 학사 시스템 사용법을 퀴즈라는 형태로 제작하여 누구라도 쉽게 접근할 수 있도록 하였고 다소 까다로운 학사 시스템 사용법을 쉽게 습득하도록 제작되었다. This paper presents the review of mobile internet platform and a mobile game contents named DQQ using WIPI. I present this DQQ system that used Jlet in the platform of Java language foundation. The school actual map and actual building pictures came to make the real scene provide. This DQQ used the form of quizes to show a school introduction and an university graduate system usage. So the students, freshmen and enrolled students can use this DQQ more easily.

Multi-component white cast irons with different levels of alloying elements such as Cr, V, Mo and W were prepared to examine their Solidification microstructure. It was observed that Chunky or nodular MC carbide was precipitated in the region of primary austenite dendrite. In the intercellular boundary, M?C₃carbide was precipitated as flower or bar shape and M₂C carbide as needle shape. In as-cast condition, the matrix was found to be composed of pearlite or pearlite + austenite composite structure. It was also known by EPMA that MC carbide was mainly composed of V, M7C₃carbide by Cr and M₂C carbide by Mo and W. With the help of cooling curves, the eutectic reactions occurred in the following order : (γ + MC), (γ + M?C₃) and (γ + M₂C). The identification of each carbide was also confirmed by X-ray diffraction pattern.

Multi-component white cast iron of 3%C-10%Cr-5%Mo-5%W was casted, and then heat treated with three different methods such as homogenizing, austenizing and tempering to observe its effects on the mocrostructure, hardness and abrasive wear resistance. While M7C₃and M?C carbides with almost pearlitic structures were observed in as-cast specimen, secondary carbide, retained austenite and tempered martensite were observed in the heat treated specimens. Hardness and wear resistance of austenized and tempered specimens were improved compared to those of as-cast specimen.

Shape modeling is an important part of computer vision. Shape models help the tasks of object representation and recognition. In this paper, curve evolution and level set algorithms are used for extracting a shape within an image. This method is based on the ideas developed by Osher and Sethian to model propagating solid/liquid interfaces moving with curvature-dependent speeds. We propose the new generalized formulation and stopping function of evolution for more accurate extraction of shape. Our method canbe applied to model arbitrarily complex shapes and has the ability to dynamically sense the topological changes of the shape during the shape recovery process.

문화대혁명(文化大革命)에 대한 한국학계의 연구현황과 앞으로의 과제

김성곤 서울대학교 국제지역원 1997 국제지역연구 Vol.6 No.1

문화대혁명이 발발한지 30년이 지난 지금 이에 대한 한국학계의 연구는 양적으로나 질적으로 외국학계의 연구현황과 비교하여 많이 뒤져 있다고 판단된다. 양적인 연구부족은 주제의 다양화에 제약을 가할 수밖에 없으며, 이는 심지어 한국에서 문화대혁명 연구가 존재한다고 말할 수 있는가에 대한 의문으로까지 발전하게 된다. 이러한 현상은 비단 문화대혁명이라는 연구주제에만 그치는 것이 아니며 중국연구 전반에 걸친 문제일 수 있다. 다른 한편, 과거 한국에서 중국연구를 한다는 것은 객관적인 연구환경의 제약등으로 인하여 어려움이 많았다. 그러나, 이러한 요인만을 탓할 수는 없는 것이 독자적인 시각을 구축하고자 하는 연구자들의 개인적 노력도 매우 부족했다는 점인데, 이는 자료이용 현황을 통해서도 알 수 있기 때문이다. 최근 외국학계에서는 기존에 축적되어 있는 연구물에 만족하지 않고 문화대혁명에 대해 보다 새로운 연구를 진행중이다. 이는 한편으로 과거와는 달리 지금은 중국현지에서의 생생한 자료수집을 통한 연구가 가능해졌기 때문이고, 또 다른 한편으로 이에 대한 연구가 지금의 중국을 이해하는데 매우 중요하다는 인식에서 출발한 것으로 생각할 수 있다. 이렇게 볼 때, 한국에서 중국연구를 보다 촉진시키기 위해서라고 문화대혁명에 대해 새로이 바라보아야 한다는 인식이 요구되며, 지금부터라도 연구물들이 축적되어야만 할 것이다. Thirty years ahve passed since China's Cultural Revolution broke out in 1966. To assert that research done on the subject by Korean acholars is far behind the quantity and quality of work produced by foreign academe, particularly the West's may not be an exaggeration. It is also no hyperbole to think that China studies in general in Korea suffers from the same backwardness. In part, this is caused by the obvious difficulties of studying a closed Communist nation like China of the past, but perhaps the more important reason is the lack of efforts by Korean scholars to do the research. One cursory glance at the bibliographic entries of their publications reveals a glaring lack of primary sources. Recently, China scholars outside Korea have begun toseriously re-examine the Cultural Revolution. New research methods and access to critical research materials since 1979 in China and the promise of better understanding the real causes of the Cultural Revolution have been the intial impetus. Better grasp of the Cultural Revolution is indispensible to understanding today's China. In this respect, Korean China scholars are advised to seriously rethink their study of the Cultural Revolution.

This study have been carried the analysis the functional composition between individual and apartment dwelling according to space activities and number of room per dwelling. The samples of individual dwelling are selected 220 housing plans among built in 1975 in Busan, and apartment dwelling are selected 60 plans from newly built in Korea over four stories building. The result are the followings: 1. The general patterns of dwelling unit in Korea have a tendency to keep many bed rooms in umber. Individual dwelling is disposed to have more bed rooms than apartment dwelling units. Average bed rooms in number per dwelling are the followings: Individual unit in Korea‥‥‥‥‥‥4.21 room Apartment unit in Korea ‥‥‥‥‥2.88 room Apartment unit in Japan ‥‥‥‥‥2.50 room Apartment unit in Europe‥‥‥‥‥2.02 room 2. The dwelling plan recently built in Korea have a tendency to keep one living room per a dwelling unit. Individual house over 25 pyeong (76㎡) dwelling space and apartment house over 20 pyeong (66㎡) have one living room in Korea. The size and area of living room space are very similar between individual and apartment house, but the analysis shows distinct difference between Korean and European as follows. -average area of living room- Indivdual unit in Korea‥‥‥‥‥‥16,77㎡ Apartment unit in Korea ‥‥‥‥‥17.03㎡ Apartment unit in Japan‥‥‥‥‥‥20.03㎡ Apartment unit in Europe ‥‥‥24.14㎡ 3. It is recommended to reduce the number of bed room and increase the area of living room for admitting to keep appropriate conditions of dwelling activities both individual and apartment house units in Korea.

The transformation and change of society since the turn of the century has been breathtaking. we have progressed from a basically agrarian society to a dynamic, industrial, post-industrial, society with a higher level of standard of living than was ever thought possible. as to the change there is no doubt. we continue to live in the society that have rapidly chanted. we have begun to recognize that social change inalves not only changes in social patterns but also in behavioral value. therefore we emphqsized the importance of hehavioral value in social pattern in order to social goal. we must first of all be considering social pattern and behavioral value. although the emphasis in this study will be on human behavior development, we must recognize the patterns in socety in which most people live are socisl gatterns comprised of many interrelated subpatterns only one of which is a human behavior as to agarian, industrial and post-industrial society. the focus of the agarian society is on anthority and custon modern society is on value and belief and contemporary society is on consumption and other-directed. the havioral criterion of agarian society tradiional society in this study emphasized the ascriptive, paarticularistic, diffure patterns and deferential s-tratification system. Industrial society (modern society) emphasized the save in scarcity psycholong. post-industrial society (contemporary society) emphasized the con-sumption in abundance psychology.

이상준,오상곤 부산대학교 1986 자연과학논문집 Vol.42 No.-

발암물질 N-nitrosodipropylamine을 유일한 탄소원으로 이용하여 분해시킬 수 있는 세균을 하천수와 토양으로부터 분리하였으며 미들 중 분해능이 우수한 EL-02311S isolate를 propionibacterium sp.로 동정하였다. Propionibacterium sp.EL-02311S는 N-nitrosodimethylamine. N-nitrosodibutylamine, N-nitrosodiethanolamine 등을 탄소원으로 이용할 수는 없었으나 이들N-nitroso compounds를 산화시켰다. Propionibacterium sp. EL-02311S에 의한 N-nitrosodipropylamine 의 분해는 gas chromatography에 의해서 측정되었으며 배양시간이 40시간정도 경과된 early stationary phase때까지 약 50%의 높은 분해율을 나타내었다. The bacteria capable of utilizing N-nitrosodipropylamine as a sole carbon source were isolated from soil and sewage water by enrichment culture. The isolate designated as EL-02311S had high biodegradability on N-nitrosodipropylamine and was identified as propionibacterium sp. N-nitrosodimethylamine. N-nitrosodibutylamine, and N-nitrosodiethanolamine were not utillized as a solecarbon source. The N-nitroso compounds that did not serve as growth substrates were oxidized in oxidation tests using resting cell of propionibacterium sp. EL-02311S. The determination of N-nitrosodipropylamine was measured by a gas chromatography. About 50% of N-nitrosodipropylamine was degraded in early stationary phase of 40 h culture.

Thoughtful transformation of Buddhism was emerged by that Mandala was transmitted to Korea, this transformation, a standard model of early temple's arrangement, was based on establishment of Buddhist temples. As the spatial system which was divided into three space ; a boundary, four sides and a main Buddhist sanctum, was transformed to mountainous temple and Mandala of Esoteric Buddhism's main thought effected and traditional belief was absorbed, these transformations pulled off the spatial system of three levels and showed the emergence of gates and sanctums which was the gate of both the four Devas and Mahavairocana and the sanctum of both Yak-Sa and Myung-Bu and gates of a mountain god, Sam-sung and Chil-Sung which was traditional space of Korea. Mandala of Avatamska unified the basic thought of Buddhist temples. On the base of these thought, the basic form of Buddhist temples's arrangement was the iconology of Mandala. In the four sides ; east, west, south and north, As the result that the function of the northern sanctum of Arhant and the southern sanctum of Myung-Bu which was comprised of Vairacana was emerged frequently but both the eastern and the western sanctum wasn't emerged was obtained, It is that as the function of the eastern and western sanctum is not necessary in making three Buddha which is the side buddha of Vairocana, making the sanctum corresponded to Vairocana is not necessary. As I result through the base of this, the spacial system of Mandala is the system of basic though in planning a Buddhist temples and means the system of Korean Mandala which is based on Vairocana from the system of three levels in Buddhist temple sites to in present mountainous Buddhist temples.
