벼 도열병균의 레이스분리 비율이 분리품종과 지역간에 어떤 차이가 있는지를 구명하기 위하여 시험을 수행하였다. 벼 도열병균의 레이스 분포는 채집지역이 동일하여도 분리품종이 상이하거나, 품종이 동일하여도 채집지역이 상이하면 레이스 종류와 비율에 있어서 큰 차이가 있었다. 정확한 레이스 조사를 위해서는 도열병균 채집지역의 객관적인 선정과 재배품종의 면적비율에 의하여 도열병균을 분리 동정하여야 할 것으로 생각된다. 식물체의 저항성측면에서 도열병균에 대한 유묘기 밭못자리상태에서의 저항성 정도와 성체기 본답상태에서의 잎도열병과 이삭도열병 발병정도와는 일치하지 않았다. 벼 품종에 대한 도열병균 침해 레이스의 수와 포장에서 밭못자리 검정의 저항성 정도와 본답상태의 잎도열병과 이삭도열병 발병정도와는 일정한 관계가 없었다.

This study analyzed settlement motivation, life satisfaction factors, policy requirement targeting return farmers on mountain village. 8 target villages where return farmers live at least 10 people were selected according as cooperation of the local governments through literature by considering the area of the whole country. The return farmers in target villages were conducted a face to face survey with village headman's pre-coordination from February to September 2013. A total of 94 surveys were performed and 87 copies were used in the analysis. According to the results, the most important factor influenced the decision to be a return farmer was "my family health(3.97)". The correlation analysis was performed to examine factors related with satisfaction of "return farmer life in general". The result showed that "change of physical health" was the most important correlativity with 0.544 correlation coefficient and 0.05 significant level and "family relationship" was followed with 0.424 correlation coefficient and 0.05 significant level. According to the "important factor for the successful return-farmer life", 42.7% of respondents chose "harmonious relationships with local residents" and "stable source of income" was chosen by 29.3% of residents. A questionnaire for the analysis of policy requirements showed that "education system related Forestry(Agriculture)" was the highest demand with 4.oo points. The result can be used as a basis for establishing policies with activation of mountain villages to attract to constantly increasing population of return farmers.

In the present study, the anticonvulsant effects of Artemisia capillaris Herba (AC) and its major constituent, esculetin (ECT), were tested and the mechanism studied. Locomotion, Myorelaxation, motor coordination and electroshock seizure experiment were conducted in mice. To identify the anticonvulsant mechanism effect of this drug, chemical-induced seizure in mice and the ionic movement in neuroblastoma cells were also observed. The ethanol extract of AC was orally administered to mice 30 min. prior to testing and ECT was intraperitoneally injected. AC and ECT treatment did not change locomotor activities as well as activities on the rota-rod, which indicates that they did not cause a sedative and myorelaxation effect. AC and ECT treatment increased threshold of convulsion induced by electroshock. AC treatment also inhibited convulsion induced by pentylenetetrazole. In the case of strychnine however, only high dose of AC treatment inhibited convulsion. AC and ECT treatment increased the $Cl^-$ influx into the intracellular area in a dose-dependent manner. On the other hand, bicuculline, a GABA antagonist, inhibited the $Cl^-$ influx induced by AC and ECT. These results indicate that ECT induces the anticonvulsive effect of AC extract through the GABAergic neuron.

The KOMPSAT-2 was developed by KARI and it was successfully launched from Plesetsk, Russia on 28th July 2006. The Korean government decided the commercialization of the KOMPSAT-2 image data and direct reception services worldwide. SPOT Image, based in Toulouse (France) was selected by KARI through an international open bidding as a foreign company for the KOMPSAT-2 image promotion over the entire world except the territory of Republic of Korea including the North Korea, the United States of America, UAE, Saudi Arabia, Kuwait, Qatar, Oman, Yemen, Egypt, Iran, Iraq, Jordan, Lebanon, and Syria. KAI (Korea Aerospace Industry Ltd.) is an engaged Korean company for this area. KARI has responsibility to operate the satellite, data acquisition, archiving for the worldwide commercialization. For the processing and delivery of the KOMPSAT-2 image data to the users of KAI and SPOT Image, KAI has the binding contract with KARI. So KAI has the responsibility for the commercial ground station operation such as user support, data processing, and the data delivery. The KOMPSAT-2 ground station is hosted in KARI, so KARI has developed the concept of KOCUST (KOMPSAT-2 Commercial User Support Team) jointly with KAI to support the data processing and delivery as KOMPSAT-2 developer and satellite operator. The main purpose of the KOCUST is to support the operational activities to provide the data and service quality to satisfy customers. KOCUST will be organized by the members of KARI and KAI together. KARI members will mainly take the role of KOCUST coordination, data processing and user support in a public sector. KAI members are going to take user desk, data validation and delivery et cetera, which are related with users. This paper describes a summarized concepts of KOCUST like organization, dedicated tasks of each part and work flow of daily operation.

With speeding up the process of being international municipality, the gravity of lacking parking lots in Shanghai urban area, which directly blocks the traffic in the city, has been revealed. This thesis analyses present automobiles parking capability and forecasts the future's needs for the city. To solve the problem, the concept could be to expand parking areas in city center recently to relax the tention and to do thoughtful planning in the near future on the foundation of fully consideration the trend. The municipal government has to set up policy properly, amplify regulations, strenthern the administration and open up a path to raise founds. Berween road system administration which is dynamic and parking lot system administration which is static, there are a knot on macroscopic meaning and an interference as well. The coordination of these two systems would be reflested on the effects of whole municipal traffic adminisration. Basically, public parking lots are city's foundal facilities, just like roads, bridges, etc. The main problems now in Shanghai are large parking space demands, insufficient facilities, cheap parking expenses comparing with the cost of parking lots construcion and poor administration. According to the forecast on social economy development, there will be 580 thousand automobiles in Shanghai by the year 2000, and the amount of private cars will increase greatly. The frequency of automobiles going out will be 1.45 million per day. Public parking lots being able to afford 105 thousand units are needed. To satisfy the demands, the recent aim of planning should be speed up the parking lots construction, the planning objective in next period should be developing reasonably and exceed the demands properly. In order to realize the planning objective, the government has to formulate correct policy and amplify administration regulations. The government has to adopt both administration and economy means, including charging parking people reasonably, collect necessary taxes, bringing the parking lots planning into general municipality planning, opening up an effective path to raise founds, such as set up founds for parking lots construction, issue bonds and stocks, get loans at home and abroad, etc.

This paper examines the trend of restructuring and direction of management response in the Large Purse Seine Fishery. The large-scale fishing industry is one of the most popular fishing areas in the coastal area, and it has been developed by providing exclusive supplies of many types of catchy fish, such as mackerel and horse mackerel through physical productivity in fleet operations. However, the Large Purse Seine Fishery has been declining in profitability due to the deterioration of the business environment since 2000. It is at a crossroads whether it will disappear or regenerate as it is. The Large Purse Seine Fishery's current problems are: firstly, the continued deterioration of the fishery business balance and worsening labor problems, secondly, insufficient freshness management and quality control after landing, and thirdly, import competition. The fourth is the intensification of the market competition, which is the evolution of fishing variability and the increase in the proportion of small fish. The fifth is the reduction of the operating fishing ground due to the suspension of mutual fishing in Korea and Japan. To address these problems and suggest management response directions for the survival of large-scale fishing businesses is as follows. First, a sustainable production system should be established through strengthening resource management and promoting international fisheries cooperation. Second, the profitability of fishing management should be improved by introducing a low-cost supplier system and securing a stable labor force. Third, we should improve the leading and quality control of catch, improve the high value-added value of catch through brand development, and secure competitive advantage with imported produce. Finally, the government should establish a cooperative system among private sector, government, and research institutes to push ahead with these tasks and strengthen the competitiveness of the front and rear industries.
