The Korean government has been implementing diverse policies with programs to generate better outcomes and results of university-industry collaboration since 1990s. In this paper, we analyze the effect of universities' competency factors on the performance of technology commercialization and start-ups respectively. We employ multiple regression models using 154 data sets from university information posting system of the Korean Council for University Education. Through conducting statistical analyses with diverse data manipulations, we obtained a high degree of significance on hypotheses, and also could compare mutual differences between the effects of university competence on technology commercialization and start-ups. The technology transfer and commercialization specifically depends on professors' patent applications and technology holding company, while start-ups does professionals in industry-university cooperation. We suggest government to spur on the ongoing customization of university-industry collaboration policy, and university to properly cope with global atmosphere changing from ivory tower to academic capitalism and start-ups promotion.

According to the 4th BPE(Basic Plan for long-term Electricity Supply and Demand), Electricity demand of Jeju island in 2012 will be reached to 682MW. Jeju island will be faced with severe shortage of electricty, also needed to find transport route to supply green energy which will be made from "Carbon free island" energy policy toward land at that time. For that reason, The plan which construct 400MW size HVDC connection line was decided for potential supply stabilization and transportation of green energy. KEPCO organized special construction office not only to observe the successful project completion which aims 2011 December but also to build up professional manpower. KEPCO is putting spur to the HVDC project these days. Construction site of converter stations has been already confirmed and contracts of cable, converter have done as per turn-key early this year. On this report, we would like to discuss about project scheme, main characteristics of system, and the furture progress plan of "Jindo~Jeju HVDC construction project expecially converter station part" which is being pushed by KEPCO.

우리나라는 1980년대 초반부터 조선산업과 더불어 조선기자재업체의 동반 성장을 추구해왔다. 그러나 조선산업발전 추이를 보면 중국이나 동남아시아로 시장이 옮겨갈 것이라는 전망이 나오고 있고, 국제해사기구(IMO)에서는 e-navigation 실현을 예고하는 등 국내외적 여건에 따른 산업계의 신속한 변화뿐만 아니라 국가적 대책과 학계의 연구개발 노력이 절실하다. 본 논문에서는 항해통신장비산업의 특징과 국내외동향, 그리고 연구개발분야를 서술하고, 대표적인 연구개발현황을 소개한다.

In general, there has been a lot of research concerned about the gear noise known to be proportional to gear transmission error for external gears likewise spur, helical gear, and hypoid gears. But, In the case of planetary gear set, gear noise study is insufficient because of the difficulty of designing, manufacturing, and understanding of the its mechanical system. This study is aimed to develop the transmission error measurement equipment for the planetary gear sets used in the automatic transmission. By comparing the results of the transmission error and noise objectively, user could select the optimized planetary gear set which has quiet noise level before manufacturing the automatic transmission.

Gear is general mechanical elements that used for power transmission between two shafts that interval is comparatively short. and it delivers big power as accurate ratio of speed. The profile of Spur gear which is the most basic factor is divided into Trochoidal fillet curve and Involute curve. Involute curve is used a lot of a shaped curve of machine parts such as a gear, a scroll compressor and a collar of centrifugal pump. However, It is poor to study the modeling of Trochoidal fillet curve and the three dimensions model shaped mathematical curve. This paper describes a mathematical model of profile shifted involute gear. and this model is based on Camus's theory. We draw three dimensions gear have accurate mathematical function using ADS, VisualLISP. and To check accuracy and perfection, we make a program of checking Interference. and use for this study.

This paper presents a finite element (FE) analysis of the torsional rigidity of a two-stage cycloid drive. The cycloid disk makes contact with a number of pin-rollers simultaneously and eccentric shafts transmit not only torque of the spur gear stage to the cycloid disk, but also that of the cycloid disk to the output disk. Contacts between the disk and pin-rollers are simplified as linear spring elements, and the bearing of eccentric shaft is modeled as a rigid ring that has frictional contact to the disk and an elastic support. FE analysis for an ideal solid cycloid drive was performed and verified by a theoretical calculation. Accurate contact forces were then estimated by iterating between FE analysis for contact forces and Hertz theory calculations for nonlinear contact stiffness. In addition, torsional rigidity of the cycloid drive is analyzed to show that the bearing and nonlinear Hertz contact theory should be considered in analysis and design of a cycloid drive, which was verified with experiments. Finally, the effects of contact stiffness, bearing stiffness and cycloid disk structural stiffness according to the cycloid disk rotation on the torsional rigidity were investigated.

The mineral industry of the United States is going through a challenging time. The US as an industrial nation faces with increasing demand in raw materials to fuel various industrial sectors but, at the same time, meeting environmental constraints associated with excavating and extracting these raw materials. In addition, gradual depletion of material resources. and the necessity of handling more complex forms of resources of primary origin have led to a decline in her resource productivity, once a strategic advantage of the U.S. As a result. the United States currently relies heavily upon foreign importation of various materials such as precious and strategic metals. However, since the US is the major consumer of most of these materials, the recovery of these values from scrap would help renew her position as a resource-producing nation, and ultimately help spur its domestic economy. Furthermore. recycling would also help maintain a clean environment and reduce energy consumption. In this paper. the author attempts to discuss opportunities and challenges lied ahead of the US mineral in relation to recovering their much-needed resources from secondary sources. The need and demand in various metals in the US will be reviewed and discussed. The implication of resource recovery from secondary sources will also be discussed. Extraction methods treating secondary sources are inherently different from those for primary sources. There is a need for new technologies which are metallurgically efficient and environmentally benign in treating secondary sources. Ways to meet such a need will be examined and key factors to be considered in approaching these challenges will be discussed.

Barley yellow mosaic virus (BaYMV-HN) occurring Haenam area was isolated by mechanical inoculation onto barley cultivars, purification and production of antibody. BaYV-HN were purified from infected plants a filamentous virus with 13 nm in diameter and 250∼300 nm and 500∼650 nm in length. Specific antibody made by injecting the purified virus to the muscle of a rabbit. In gel-diffusion tests antibody to BaYMV-HN did not make spur with tow Japanese BaYMV isolates BaYMV-II-1 or BaYMV-III. BaYMV-HN showed the symptom of yellowing and necrosis in host plants. Mechanical inoculation tests with Japanese barley cultivars showed that BaYMV-HN infected New Golden, Akagi Nijo and Tosan Kawa 73, but did not infect Amagi Nijo, Haruna Nijo, Ishukushirazu (ym3), Misato Golden (Ym1), Kashimamugi, Joshushiro Hadaka and Mokusekko 3 (ym1). In Korean barley cultivars, some of the naked barleys which are Hinssalbori, Kinssalbori, Saessalbori and Saechalssalbori were not infected by BaYMV-HN. However, it infected all the covered barley cultivars and the beer barley cultivars. BaYMV-HN had two RNAs, RNA 1 (7.6 Kb) and RNA 2 (3.5 Kb), and one coat protein (33 KDa).
