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,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.

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.

In 2004, the Incheon Urban Development Corporation held a design competition for the Song-Do apartment complex development. Several projects that won the prize in the recent design competitions were reviewed to look around the current design tendency, and current conditions of the site were surveyed. The authors tried to combine digital and environment-friendly factors, considering the site condition. Because the site is on reclaimed land and is located at the center of the information-technology industrial area, these two factors inform the main concept of this project. The site was divided into two different zones : the Ocean Zone and the Digital Zone. The 'community spaces'(community street, community plaza and so on) were designed for the various activities of the residents. The Patios, 'private' community spaces, included many facilities for play, appreciation, rest, exercise, refreshment and gathering. To avoid common landscape styles in the patios, simple and minimal forms were designed. The environmental sculptures were carefully planned, allocated and shaped with digital technology, based on the 'Present and Future of Song-Do'. The authors also tried to introduce environment-friendly factors, such as the green roof system, wall planting, and the water recycling system. This project is following the M.A. (Master Architect) process, and is still being modified to make the hi-tech and environment-friendly apartment complex.

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.

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.
