  • Solid phase enzyme linked immunosorbent assay (ELISA) was developed to detect the whole cells of Edwardsiella tarda from infected tissues of flounder. Cross-reaction test was performed by ELISA against fish pathogens such as A. hydrophila ATCC7966. V. anguillarum HYUFP5001, Y, ruckeri 11-4, E. ictaluri and Streptococcus sp. NG8206. Rabbit anti-E, tarda Edk-2 sera highly cross-reacted with A. hydrophila ATCC7966 and V. anguillarum HUFP5001. However, the cross-reaction was removed by using the anti-serum pre-adsorbed with A, hydrophila ATCC7966 FKC. The intra-species cross-reaction among E. tarda isolates was very high. ELISA with the whole cell antigens present in tissue homogenate appeared with highly decreased sensitivity, presumably by the co-coating of lipid or proteins in tissues. Thus, it would be necessary to use the infected tissue homogenates diluted more than 100 times with PBS for diagnosis. Interestingly, compared with the using of FKC antigen, the direct detection of viable cells in tissue homogenate showed more sensitive results with detection limit of $1{\times}10^3$ cells/ml in buffer or diluted tissue homogenate. Consequently, the ELISA method developed in this study was specific, rapid and sensitive for diagnosing edwardsiellosis.

  • This case is to analyze the structure of technology convergence with social network analysis. More specifically, the convergence structure among input technologies mediated with products is analyzed with 2-mode social network analysis. Products are identified in project's goal and coded as the Korea Standard Industrial Classification. The input technologies are coded as the National Science Technology Classification. The subjects were 401 R&D projects applied to '2012 Convergence Technology Development Project for Small and Medium Businesses' promoted by Korea Technology & Information Promotion Agency for Small and Medium Enterprises. IT sectors had the structure of a particular input technology connected to many products, BT sectors also had a few input technology connected to many products but most were connected to specific products. Therefore We have realized that each convergence area had different convergence structure. There were the difference of connectivity centrality between input technologies and input technologies mediated with products. For IT sectors, the embedded S/W were the highest in both cases. For BT sectors, functional cosmetic development and fermentation technology were the highest in input technologies but fermentation technology was not the highest in input technologies mediated with products. This case defines the convergence based on the real projects and the use for managing and planing projects. Therefore, this case was to make a tool to analyze and design technology convergence projects.

  • Open innovation is a phenomenon that has been widely accepted by both practice and theory over the last few years. On the contrary, partner relationships have attracted little attention while the open innovation could not be emerged without the link to partners. This paper identifies and evaluates a framework for the partner relationships and open innovation processes. Based on the literatures regarding open innovation and partner relationships, we propose the framework of matrix type. We present results based on 352 open innovation cases reported during 2002-2009, and each case is classified into 5 different categories of the framework. JV-C(Joint Venture relationship & Coupled process) archetype has dominated the cases with 178 cases(50.6%) where JV-O(Joint Venture relationship & Outside-In process) follows JV-C with 124 cases(35.2%). No significant change has been found in the number of cases after 2003 when open innovation firstly suggested. However, the number sharply increases in 2009 by boom in JV-C and JV-O. These results show the importance of partner relationships and preference toward Joint Venture relationship in open innovation, while the conventional approaches has just focused on value-chain partnership. We find remarkable collaboration cases contributed by universities and government invested research centers, so the role of non-profit R&D organizations has also been discussed.

  • 지구는 현재 태양계에서 액체 상태의 물이 표면에 존재하는 유일한 천체이다. 하지만, 고체 또는 기체 상태의 물은 태양계의 다른 행성이나, 위성, 소행성, 혜성 등에도 풍부하게 존재하고 있다. 풍부한 액체 상태의 물은 지구 표면에서 일어나고 있는 기후의 변화, 해류의 이동, 퇴적 및 침식 작용, 화산활동과 같은 여러 지구과학적 현상에 밀접하게 관여하고 있을 뿐 아니라 생명의 탄생과 진화에도 매우 중요한 역할을 하였다. 현재 지구 표면에 액체 상태의 물이 존재할 수 있는 이유는 태양으로부터의 거리, 지구의 조성 및 크기 등과 관련된 지구 표면의 물리-화학적 조건이 액체 상태의 물이 존재할 수 있는 조건과 일치하고 있기 때문이다. 이와는 달리 지구보다 태양에 더 가깝게 위치하고 있고, 두터운 이산화탄소 대기를 갖고 있어 표면의 온도가 매우 높은 금성의 경우 H2O는 기체 상태로 존재하며, 지구보다 더 멀리 떨어져 있고 희박한 대기를 갖고 있는 화성의 경우에는 현재 H2O가 고체 즉 얼음의 형태로 존재한다. 태양계를 탄생시킨 태양계 성운에서는 압력이 너무 낮아 액체 상태의 물이 존재할 수 없으며, 고온에서는 기체 상태로 매우 낮은 저온에서는 얼음의 형태, 또는 함수 광물 내에 포함되어 존재할 수 있다. 지구와 같은 규모의 행성은 비교적 중력이 작아 태양계 성운의 기체를 거의 끌어들이지 못했다. 따라서 현재 지구에 존재하는 물은 대부분은 고체 상태로 지구에 집적되었을 것이다. 하지만 지구가 탄생한 위치에서 초기 태양계의 온도는 얼음이 형성되기에는 너무 높았기 때문에 좀 더 먼 곳에서(현재의 목성 위치보다 바깥쪽)에서 생성된 얼음 즉, 혜성이 태양계 안쪽으로 들어와 지구에 물을 공급했거나 함수광물을 포함하고 있는 소행성(예를 들어 CI chondrites와 같은 조성의)이 물을 가져왔을 것으로 생각되고 있다.서의 활성화는 어미 변환과 관련된 영역이라기보다는 산출시 관련되는 articulation, motor coordinate관련 영역으로 추정되고, 측두엽의 활성화는 형태소, 의미 관련 지식의 data base로 추정된다. 또한 우반구 전두엽 부분에서 관찰된 활성화는 억제관련 영역으로 짐작된다.러한 동물실험이 그 기초를 제공해 줄 수 있을 것이다. 또한 행동성향 및 기억의 종류에 따른 약물효과의 차이는 기억과 관련된 질병인 알츠하이머 환자에 있어 개개인에게 맞는 적절한 특징적인 치료약물이 존재할 것이라는 가능성을 제공해줄 뿐만 아니라 학습과 기억력 증진 효과를 기대해 볼 수 있을 것이라고 생각된다. 및 지역산업발전의 기획${\sim}$조정기구로서, 선진국의 지역발전기구(Regional Development Agency : RDA)인 지역전략산업기획단이 2002년도부터 산업자원부와 9개 시도에 의해 설립되어 지역네트워크의 활성화와 클러스터의 형성 촉진을 하게 되었고 2004년도에는 13개시도로 확대${\sim}$운영되고 있고, 지역특화사업(H/W)과 지역산업기술개발과제(S/W)와 함께 패케지 형태로 지원되며, 주요역할은 크게 지역산업의 정책기획 분야와 평가관리, 지역혁신역량 조사 및 DB구축 등으로 구분된다. 그중에서도 권역별, 지역별, 지역산업진흥사업 육성과 중장기 산업발전계획을 수립하기 위하여 지역혁신역량을 바탕으로 한 지역 Technology Road Map(TRM)작성사업은 전국공통의 1단계 사업으로 실시 ?榮쨉?, 2005년 3월 기준으로 9개 지역(강원, 대전, 충남, 충북, 경북, 울산, 전남, 전북, 제주) 26개 산업분야를 대상으로 23개가 완료된 상황이다. 이를 근거로 한 지역정책과 R&D 과제 및 필요 인프라의 도출이 체계적으로 구축되어 지역산업 발전을 위한

  • In the circumstance that high oil price state is continued over the world, the investment in crude oil development by oil major is a trend of increasing. Recently the number of delivered drill-ship for 5 years has been sharply increased all over the world and about twice than that of past 30 years. As addition to the increase of the drill-ship demand, the operation of drill-ships which is delivered recently is about 3,000 meters, ultra deep sea, on average and the work area is expending. Accordingly the drilling system including the size and length of pipe for drilling has been bigger and bigger and the power supply equipment for operation system also has large capacity. Unlike merchant vessel, high power and high voltage of diesel generators are required for drill-ship for which the demand for V-type 320 bore of diesel generator has increased. It is on the raised that the importance of lubrication oil cleaning for diesel generator on drill-ship which has longer time for construction, and also long term low load operation is unavoidable during commissioning of equipments. Recently it was reported that engine crankpin was damaged due to the hard contact caused by the abnormal wear down(Cam wear) on crankpin and bearing. The same pattern of wear down was found through the inspection on series vessels and the other vessel under commissioning. The purpose of this paper is to analyze of the wear mechanism based on the observation and theories and objective research from actual cases and to prepare the counter measures to avoid foreseeable damage when the lubricating oil is not properly cleaned.

  • Several problems caused by inevitable increment of airplane have been issued. The most effective solution to solve the issues is considered as establishing appropriate Air Traffic Management (ATM) that reduces aircraft's delay at an airport and intensify the airport's capacity. The purpose of this paper is to produce the optimum aircraft schedules that maximize the aircraft throughput by smooth air traffic flow near terminal area of an airport In this paper, mathematical formulations of the scheduling problem are firstly specified. Based on the mathematical modelling, an Optimization-Based Flight Scheduler that provides the optimum flight schedules for arriving aircraft is developed by introducing the Mixed Integer Linear Programming(MILP) and the Genetic Algorithms(GA). With this scheduler, we calculated the optimum schedules to compare to real schedule data from an Incheon Airport. As a result, it is validated that aircraft throughput produced by the optimum schedule is much better than that of the schedule from the Incheon airport. The optimization-based flight scheduler is expected to deal with problems due to the aircraft saturation in near future.

  • An experiment was conducted to evaluate a ventilation system, which was devised to encourage farmers to use the enclosed growing and finishing pig housing system. A roof-air-entry ventilation system in winter and a side-wall-air-entry system in summer were evaluated. Air flow rate on the floor level which is the low part of pen and the living area of pigs in the enclosed growing and finishing pig house during winter was measured at 0 to 0.19 m/s at the minimum ventilation efficiency of 1,440 $m^{3}/h$. During summer the air flow rate was detected at 0.07 to 0.42 m/s at the maximum ventilation efficiency of 24,000 $m^{3}/h$. Therefore, it is concluded that the side-wall ventilation system is suitable for growing and finishing pigs in the enclosed house during the days of mid-summer and the roof-ventilation system was suitable during the coldest days of mid-winter. In addition, although the enclosed pig house has the system in which air exhausts through only one side wall, air should enter through both-side walls for the better ventilation performance.
