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.

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.

SHS법에 의한 Ti-Si계 세라믹스의 합성 및 소결체의 특성에 관한 연구

김도경,박성,조덕호,조건,이형복,Kim, Do-Kyung,Park, Sung,Cho, Duk-Ho,Cho, Kurn,Lee, Hyung-Bock 한국세라믹학회 1994 한국세라믹학회지 Vol.31 No.3

Intermetallic Ti-Si system ceramics were synthesized from stochiometric mixtures of titanium and silicone powders in vacuum by Self-propagating High-temperature Synthesis(SHS). In each cases of Ti5Si3, Ti5Si4 and TiSi, and TiSi2 synthesis, 20wt% product dilution, direct ignition and SHS chemical furnace method were employed. The combustion modes, which were observed during the synthesis process by using the high speed camera, of Ti5Si3, Ti5Si4, TiSi, and TiSi2 exhibit spin, osciallatory, steady-state, and spin combustion, respectively. With increasing Ti/Si molar ratio an decrease of combustion velocities was found. From the results on the measurement of the flexural strength, the specimen hot pressed at 135$0^{\circ}C$ for 30 min using synthesized Ti5Si4 powders showed the highest flexural strength at 215 MPa.

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.

건축설계 측면에서 본 수덕사 대웅전의 평면과 가구 특성에 관한 연구

김도경,Kim, Do-Kyoung 한국건축역사학회 2008 건축역사연구 Vol.17 No.4

In this study, I attempted to the architectural design characteristics of Daeung-Jeon in Sudeok Temple. For this purpose, After I set up several assumptions in the basis of the general characteristics of Korean wood architecture, and then, analyzed floor plan, structural formation and section sizes of structure and bracket members in relation to module and unit. As the results, the characteristics of the design process of plan and structure are follows. (1) 1 ja(尺), the unit applied to this building is measured $307.6{\sim}318.3mm$) and the average is 312.9mm (2) It is estimated that the floor plan designed on the basis of the top of columns. By the applied unit, every bay of the front side and the side is each designed by 15 ja and 8.5 ja. (3) The section is composed of piled members which have same section size. As basic module of section size called 'jae(재;材)', it is estimated at width 0.45 ja by height 0.75 ja. And as the secondary module, height between jae and is called 'gyoe(계;)' and it wes designed by three height size of 0.25 ja, 0.27 ja and 0.30 ja, (4) It is estimated that the section plan was designed by the order as follows. Firstly, the horizontal position of purlins wes decided on the basis of the intersection point of long and short rafters, and then the position and the section size of purlins and jangheyo(長舌) wes decided on the basis of the slope of roof and rafters. Secondly, going down from purlins, the members of structure composed of 'jae' and 'gyoe' was repeated. Lastly, for the purpose of linking the structure members located on the center line of adjacent purlins organically, the height of whaban(화반) was controlled.

중국 고건축 기행(1) - 산서성을 중심으로

김도경,Kim, Do-Gyeong 대한건축사협회 1996 建築士 Vol.1996 No.7

역사적으로 우리나라의 전통건축은 중국건축과 밀접한 관계를 지니고 있다. 그래서 중국이 자본주의 경제체제를 수용하면서 개방되자마자 중국건축에 관심을 가지고 있던 많은 사람들이 중국을 방문하게 되었다. 그리고 여러 사람들에 의해 중국건축에 대한 소개가 이루어졌다. 그러나 중국은 워낙 방대한 영토를 지니고 있고, 아직은 중국을 여행하는데 교통이나 안전 등 많은 문제가 있어서 국내에 소개된 중국건축은 빙산의 일각에 불과하다고 할 수 있다. 필자는 지난해 9월 28일부터 10월 25일까지 산서성을 중심으로 한 중국의 일부를 답사한 바 있다. 이번 답사 지역 중에는 기왕에 국내에 잘 알려진 곳도 있고 그렇지 않은 곳도 있다. 이번 기회에 그 답사내용을 사진과 평면 스케치를 곁들어 소개하고자 한다. 중국건축에 대한 이해와 연구에 조금이나마 도움이 되었으면 한다.

IMF 이후 아파트 단지 옥외공간 명칭변화와 이미지 특성 연구

김도경,정주석,Kim, Do-Kyong,Jeong, Joo-Seok 한국조경학회 2007 韓國造景學會誌 Vol.35 No.1

This study intended to provide basic data for the future naming of outdoor areas in apartment complexes by conducting research into the causes, lengths of time, trends, and characteristics of the changes of outdoor space names of apartment complexes and by analyzing current images of outdoor space names. In order to explore the causes and intervals of changes of outdoor spaces in apartment complexes, related literature was surveyed, with on-site inspections being made to examine outdoor space names by time intervals. At the site selected for this study, a case study was conducted to determine the outdoor space names and to understand the trends in the changes of these name in the apartment complexes. Moreover, a questionnaire survey incorporating selected adjectives was administered to investigate the perceived images of outdoor space names and finished construction spaces. The results are as follows: 1. Causes driving changes in apartment outdoor space names included changes in apartment complex planning concepts, changes in the values and demands of apartment buyers, social values, and changes of brand. Intervals of changes were divided into two with the 1997 IMF financial restructuring of the Korean economy as the division. 2. In regards to trends in changes of apartment outdoor space names and their characteristics, various features applied to spaces have caused many changes, which resulted in the phrase $'\bigcirc\;\bigcirc+garden'$, expressions suggesting various images, and Korean names. 3. The results of the analysis of apartment outdoor space names and finished construction images revealed that there was a difference in all the spaces. This is thought to be mainly due to such issues as paved min, the use of ready-made goods, and figurative expressions. The results of the study above indicate that changes in outdoor space names of apartment complexes have been made simply as part of marketing strategies, with no consideration of the residents. Apartments, an important means of housing in Korea, account for more than 50% of Korea's total housing, and the naming of outdoor space serves as an essential element for residents. Therefore, outdoor spaces of apartment complexes should be named in consideration of the final appearance after construction is completed, with effort by the industry being required.

흰쥐 해마에서 Norepinephrine 유리에 미치는 Protein Kinase C 의 영향

김도경,이영수,최봉규,Kim, Do-Kyung,Lee, Young-Soo,Choi, Bong-Kyu 대한약리학회 1995 대한약리학잡지 Vol.31 No.2

The effects and interactions of $4{\beta}-phorbol$ 12,13-dibutyrate(PDB) and polymyxin B(PMB) with adenosine on the electrically-evoked norepinephrine (NE) release were studied in the rat hippocampus. Slices from the rat hippocampus were equilibrated with $^3H-noradrenaline$ and the release of the labelled product, $^3H-NE$, which evoked by electrical stimulation$(3\;Hz,\;2\;ms,\;5\;VCm^{-1},\;rectangular\;pulses)$ was measured. PDB$(0.3{\sim}10\;{\mu}M)$, a selective protein kinase C(PKC) activator, increased the evoked NE release in a dose related fashion while increasing the basal rate of release. And the effects of $1\;{\mu}M$ PDB were significantly inhibited by $0.3\;{\mu}M$ tetrodotoxin(TTX) pretreatment or $Ca^{++}-free$ medium. $PMB(0.03{\sim}1\;mg)$, a specific PKC inhibitor, decreased the NE release in a dose dependent manner while increasing the basal rate of release. Adenosine $(1{\sim}10\;{\mu}M)$ decreased the NE release without changing the basal rate of release, and this effect was significantly inhibited by 8-cyclopentyl-1,3-dipropylxanthine$(2\;{\mu}M)$, a selective $A_1-receptor$ antagonist, treatment. Also, adenosine effects were significantly inhibited by PDB-and PMB-pretreatment. These results suggest that the PKC plays a role in the NE release in the rat hippocampus and might be participated in a post-receptor mechanism of the $A_1-adenosine$ receptor.

김도경,문정민,Kim, Do-Gyoung,Moon, Jeong-Min 한국주거학회 2013 한국주거학회 논문집 Vol.24 No.3

Today's urban spaces require diverse functions according to segmented social changes. Urban public space needs to be a field of mutual exchange, respect of diversity, and communication. According to these needs, an identity which reaches the public should be developed and realized. Therefore, this study is to present indexes for evaluating public space as a means to improve urban identity along with developing an awareness of possible problems. For this purpose, this study found out and analysed factors of evaluation indexes for the most fundamental public spaces which form cities in order to develop directions for deciding on indexes for public space and activation of that public space. An empirical analysis was conducted with the use of a questionnaire with evaluation indexes, reliability, and validity of properties of the space to be analysed and the evaluation items were tested. Based on the results, the study compared and analysed the differences between groups with independent variables (evaluation indexes) and general characteristics through a t-test. As a result, it was discovered that easy and safe accessibility in the use of urban parks as public space was statistically significant. Such results show that accessibility is the most significant factor in the use of parks.
