For the semiconductor device safety from over current in the digital electronic circuit system must be surely designed that it's surface mount type micro fuse device. In this paper, We has analysed to the fusing character of micro fuse as a function changed thickness of thermosetting ink epoxy. To the change of thermosetting ink epoxy thickness with in production lot, in the electrically character (fusing test in the 2 multiple over current and 10 multiple over current, surface temperature test in the 1.25 multiple over current) of micro fuse has been tested. According to the electrically character result, changed thickness of thermosetting ink epoxy in designed micro fuse withheld direct effect in both end resistance changes. Also, because high thermal energy in the micro fuse test of over current was occurred to effect such as thermal runaway and explosion. Therefore, screen printing process in the design of micro fuse using thermosetting ink epoxy is very important for production quality improvement.

김도경,김건영,Kim, Do-Kyong,Kim, Kun-Young 한국조경학회 2011 韓國造景學會誌 Vol.39 No.5

지구단위계획에서는 형식적으로 조성되는 경직된 제도의 모습을 벗어나기 위하여 구역 내 총체적인 계획의 일부분으로 건물 세부 기준뿐만 아니라, 공개공지의 배치, 형태 및 포상에 대한 가이드라인을 제시하고 있다. 문제점을 가지고 있는 도시환경정비기본계획(2005년 수립)이 그동안 도심부의 여건 변화를 반영하기 위하여 재정비되면서 구역별 개발유도 지침에 공개공지 부문이 세분화 되었다. 이러한 제도가 공개공지계획에 있어 실효성 있는 제도인지 개정 전 후를 비교해 본 결과, 도시 및 주거 환경정비법 상 공개공지 관련 수립지침의 부재로 공개공지계획 시 공통적으로 지켜야 하는 건축법과 별반 다를 것이 없는 항목이 신설되어 개정되기 전과 괄목할만한 변경사항이 없다는 분석 내용이다. 지구단위계획과 비교 분석해 본 결과, 지구단위계획 상 공개공지계획은 상위법인 건축법, 서울시 건축조례와 동일한 조성 기준이 한가지만 존재하고, 대부분은 제1종지구단위계획수립지침을 통해 신설된 조성 기준들이다. 반면, 도시환경정비기본계획상 공개공지계획의 속성은 절반이 상위법인 건축법과 서울시 건축조례와 동일하거나 유사한 항목이다. 건축법과 같은 공통적으로 지켜야 하는 상위법에서는 설치기준 등과 같은 필수적인 요소들의 나열이라면, 하위법에서는 주변 환경과 공개공지의 적극적인 연계로 공개공지의 의의에 맞게 구체적이고, 실효성 있는 미시적인 측면의 조성 기준이 만들어져야 할 것이다. The district units planning suggests not only detailed standards of building as parts of the whole plan in the district but also a guideline of the arrangement, shape and pavement of the public open space, in order to move away from the rigid image of an institution which causes the formal creation of it. This triggered various problems. While the basic plan for adjustment of urban environments(established in 2005) was being reorganized in order to reflect changed conditions of the city center, the sector of public open space was subdivided according to the guidelines of development by district. We conducted a comparative analysis of conditions before and after the adjustment, so as to examine whether or not the reorganized institution is effective for the plan of public open spaces. The analysis showed that there was no remarkable change between the basic plan and the reorganized institution in that items which were not any different from the existing building codes were established due to lack of guidelines related to public open space under the law of urban and residential environmental improvement. Low regulations should set up criteria for establishment from a concrete, effective microscopic aspect appropriate to the significance of public open space by the linking of public open space and the surrounding environment, whereas high regulations such as building codes should specify essential components.

김도경,여상건,Kim, Toh-kyung,Yeo, Sang-geon The Korean Society of Veterinary Science 2003 大韓獸醫學會誌 Vol.43 No.3

The VP2 gene of infectious bursal disease virus (IBDV) Chinju which was previously detected in Chinju, Korea was cloned and sequenced to establish the information for the development of genetically engineered vaccines and diagnostic reagents against IBDV. The nucleotide sequence of the entire Chinju VP2 gene consisted of 1,356 bases long encoding 452 amino acids in a single open reading frame (ORF). It consisted of 368 adenine (27.1%), 363 cytosine (26.8%), 339 guanine (25.0%) and 286 thymine (21.1%) residues. The predicted $M_r$ of the Chinju VP2 protein was 48 kDa, and the protein contained 13 phosphorylation sites by protein kinase C, casein kinase II or tyrosine kinase, whereas 3 asparagine-linked glycosylation sites were recognized. The nucleotide sequence of Chinju VP2 ORF had a very close phylogenetic relationship with 98-99% homology to that of the very virulent IBDVs (vvIBDVs) HK46, OKYM, D6948, UK661, UPM97/61 and BD3/99. Also, the Chinju VP2 protein revealed a very close phylogenetic relationship with 99-100% homology to that of these vvIBDVs. The Chinju VP2 protein had 100% amino acid identity in the variable region of residues 206-360 with that of the D6948, HK46, OKYM and UK661, as well as 100% identity in two hypervariable regions of residues 212-224 and 314-324 with those of the D6948, HK46, OKYM, UK661, UPM97/61 and BD3/99. The amino acid sequence of the chinju VP2 protein contained a serine-rich heptapeptide of SWSASGS as in these vvIBDVs.

돼지로부터 분리한 Staphylococcus hyicus subsp hyicus 489주의 protein A 존재여부와 함량을 indirect hemagglutination 및 enzyme-linked immunosorbent assay(ELISA)법으로 조사하였다. Indirect hemagglutination text에 의하여 cell-bound protein A 및 extracellular protein A 보유균은 489주 중 각각 87.7% 및 36.0%로 나타났다. ELISA법에 의한 이들 균의 protein A함량 측정에서 전균주의 extracellular protein A는 1ng/ml미만이었으며, cell-bound protein A함량은 대부분의 균주에서 1ng/ml 미만이었고 11주가 25~108ng/ml 수준이었다. The Presence and quantity of protein A in Staphylococcus hyicus subsp hyicus isolates from pigs were determined by indirect hemagglutination test and enzyme-linked immunosorbent assay(ELISA). Cell-bound and extracellular protein A was demonstrated in 87.7% and 36.0% of 489 isolates, respectively, by indirect hemagglutination test. When contents of the protein A were estimated by ELISA method, all of the isolates that were positive to protein A in indirect hemagglutination test produced extracellular protein A of less than 1ng/ml. Most of the isolates produced cell-bound protein A of less than 1ng/ml, whereas 28 isolates produced 1 to 35ng/ml and 11 isolates produced 25 to 108ng/ml.

김도경,박성,조건,이형복,Kim, Do-Kyung,Park, Sung,Cho, Kurn,Lee, Hyung-Bock 한국세라믹학회 1994 한국세라믹학회지 Vol.31 No.11

Ultra-fine $\beta$-SiC powders were fabricated by self-propagating high temperature synthesis process (SHS) using chemical furnace. The dependences of the C powders with different surface areas, the molar ratios of C/Si, the weight ratios of chemical fuel content, and pellet diameter-size on synthesis were investigated. Compositional and structural characterization of these powders was carried out by scanning electron micrograph and X-ray diffraction. The $\beta$-SiC powders which had C/Si mole ratio=1.05, 3 times chemical fuel contents, and pellet diameter=20 mm were optimum for synthesis efficiency. By optimizing process-variables, it is possible to fabricate $\beta$-SiC powders which have little secondary phases ($\alpha$-SiC).

드림랜드 부지는 산으로 둘러싸인 강북지 역의 유일한 평지화 된 놀이공원이었으나, 현재는 시설 노후화와 방치로 인해 지역 거점공원으로서의 기능이 상실되었다. 부지 주변은 기존의 밀집주거와 새로 조성될 뉴타운 등이 혼재할 것이며, 특히 지역 여건상 강북지역의 도시환경 개선을 위한 대형공원이 필요하다는 측면에서 강북 대형공원 조성사업이 대두되었다. 본 연구는 강북 대형공원 조성사업 국제 현상공모에서 우수작으로 선정된 작품의 설계전략과 내용을 서술하고자 한다. 계획안의 주안점은 다음과 같다. 첫째, 산지형 공원의 새로운 가능성을 찾고자 하였다. 지극히 일상적인 생활공간으로서 산책과 등산, 체력단련시설 등 제한적으로 이용되는 산지형 공원을 선조들이 산을 즐겼던 그 정취를 재현해 보고자 하였다. 둘째, 사회성 강한 자립공원을 만들고자 하였다. 도시 속에 섬으로 존재하는 녹색 숲으로서의 공원이 아닌 자체적인 변화의 에너지를 발산하면서 도시와 적극적으로 소통할 수 있는 공원이 되도록 하였다. 셋째, 다랑이 논은 자연과 더불어 사는 우리의 삶의 방식과 이념을 표현한 실체적 공간이었으며, 우리의 대표적인 향토적 경관이기도 하다. 이런 다랑이 논은 세 개의 낮은 산으로 둘러싸인 대상지를 아우를 수 있는 디자인 모티브였으며, 산에서부터 자연스럽게 흘러내리는 정겨운 풍경은 도시속의 명소로서 사람들의 이야기를 담아낼 수 있도록 계획하였다. Although the Dreamland site was the only flat amusement park in the northern part of Seoul, the site lost its function as a regional park due to aging and, therefore, was no longer in use. The site is surrounded by currently existing high dense low-story housing blocks and proposed new towns. A renovation plan for Dreamland was raised by the City of Seoul to enhance the quality of the urban environment in the northern part of Seoul. This study articulates the design concepts and strategies of the prizewinning work of the International Design Competition for Gangbuk Large Park. The three key points can be summarized as follows: First, this design proposal tried to find a new possibility for a large mountain park in an urban areas. These days, mountain parks are used limitedly as ordinary living spaces for activities such as a walking, hiking, and physical training. New strategies were sought to reconstruct the sentiment with which our ancestors enjoyed the mountains. Second, this proposal tried to make Dreamland a socially self-sufficient park. We designed a park which generates self-energy and which communicates with the city, not a park which only exists as a green island in a city. Lastly, rain fed paddy fields, a typical Korean vernacular landscape, was a tangible space which represented people's life-styles harmonizing with the nature. Rain fed paddy fields is a design motif which puts the three surrounding mountains together with the site. It is expected that the new design will works as a noted place.

여의도 한강공원 조성계획

김도경,최원만,홍형순,Kim, Do-Kyong,Choi, Won-Man,Hong, Hyoung-Soon 한국조경학회 2008 韓國造景學會誌 Vol.36 No.2

한강은 대한민국 수도 서울을 가로지르는 거대한 스케일의 매력적인 강이다. 그러나 근대화 과정에서 일괄적 인 호안공사로 직강화 되어 본연의 자연스러움과 하천의 건강성을 점차 상실하였다. 이를 극복하고 한강 중심의 개혁을 통해 수변도시 서울의 이미지를 확고히 하여 고급 브랜드화 하겠다는 한강르네상스 계획이 진행 중이다. 본 연구는 한강르네상스 사업의 일환으로 진행된 여의도 한강공원 국제 설계경기 공모 당선작의 설계전략과 내용을 서술하고자 한다. 계획의 주안점은 기본적으로 여의도 한강공원이라는 새로운 워터프런트의 정체성을 대변하는 3가지 이슈를 가지고 접근하였다. 첫째, 여의도는 비록 개발에 의해 인공적인 섬으로 변했지만 한강에서 과거의 기억을 가지는 유일한 공간이다. 모래섬의 서정성과 물가의 감성적인 기억을 가지는 장소로 계획하고자 하였다. 둘째, 한강르네상스 프로젝트의 6가지 지구 중 서로 마주 보고 있는 용산과 여의도는 중심지 역으로서 국제적인 금융, 업무지 역으로 조성된다. 용산의 철저히 도시적인 모습에 반해, 목가적 풍경과 고층건물이 절묘하게 어우러지는 색다른 풍경의 여의도 워터프런트를 제안하여 용산과의 적극적인 상호관계를 형성하고자 하였다. 마지막으로, 본 계획안에서는 현상공모 범위 밖인 여 의도공원과 본 현상공모 대상인 여의도 한강공원 관계를 재설정해 보고자 하는 것이었다. Ran Gang is a huge, attractive river which meanders through Seoul, the capital of South Korea. However, during the modernization of Seoul, the river gradually lost its natural beauty and healthy condition. Han Gang Renaissance is a project to upgrade the look of the Seoul waterfront, by overcoming this disaster and reorganizing the surroundings of Han Gang. This research articulates the design strategies and description of the prizewinning work of the International Design Competition for Yeouido Riverside Park that was linked to the Han Gang Renaissance Project. There are three key points that basically speak to the identity of the new waterfront, Yeouido Riverside Park. First, the current day Yeouido was recreated as an artificial island through the rapid expansion of the city and the initiation of the shore protection works. However, because it is the only island still remaining that shows the history of Han Gang, the park was designed to be the place which preserves the lyric of sand island and the emotional memory of riverside. Secondly, among the six districts of the Han Gang Renaissance Project, the two districts that are facing each other, Yongsan and Yeouido, are the central areas promoting international finance and business. Despite Yongsan's complete urban image, the exquisite harmony of pastoral scenes and skyscrapers of the Yeouido waterfront is presented to develop an active mutual relation with Yongsan. Lastly, this design scheme re-establishes the relationship between this competition's site, Yeouido Riverside Park, and a neighboring site, Yeouido Park.

김도경,Kim, Dokyoung 한국건축역사학회 2014 건축역사연구 Vol.23 No.5

Source criticism is very important on the research of architectural history as well as general history. In this point this research studied on the original form and change of Dokrak-dang that is very important building in architectural history of Korea. The result is as in the following. Dokrak-dang that Whoijae built at first was three by two kans size that had daecheong of four kans and ondol-bang of two kans. Gye-jeong that Whoijae built was three kans size that had daecheong of two kans and ondol-bang of one kan. After Whoijae died, Dokrak-dang's ondol-bang was changed to maru between 1555 and 1556 and ondol-bang in west side and stack room was added in 1630. Gye-jeong was changed to ㄱ-shaped floor plan that was added up two kans from three kan's 'ㅡ'-shaped one.
