호림수산(滸林水産) 양식장(養殖場)에서 사육하고 있는 12개연령(個年齡)의 향어(香魚)(이스라엘잉어) 39마리중 36마리로부터 큰 후흡반(後吸盤)으로 세개내면에 고착(固着)하고 있는 132개체(個體)의 물고기거머리를 1986년(年) 4월(月) 7일(日)에 채집하여 충체(蟲體)의 구조(構造)를 상세(詳細)하게 검토(檢討)하였다. 충체(蟲體)는 짧고 두꺼우며, 전흡반(前吸盤)에는 두 짝의 안점(眼點)이 있다. 후흡반(後吸盤)은 최대체폭(最大體幅)의 $0.3{\sim}0.4$배(倍)이며, 유안점(類眼點)이 없다. 제1측방(第1側方) 돌출부(突出部)는 제(第)2의 것보다 작으며, 제(第)$2{\sim}5$의 것은 크지만 제(第)$6{\sim}11$의 것은 후단(後端)에 갈수록 점점 작아진다. 원체절(原體節)은 3체환(體環)으로 되어 있으며, 다시 작은 구조(溝條)로 분절(分節)되어 있다. 원체절(原體節)에 있어서 체환(體環)의 최다수(最多數)는 14개(個)이다. 이러한 형태학적(形態學的) 특징(特徵)으로 미루어 보아 Trachelobdella sinensis Blanchard, 1896이라고 동정(同定)한다. 이 물고기거머리는 저자(著者)가 우리나라에서 처음으로 발견(發見)하였으며 새로운 분포지역(分布地域)으로서 한국(韓國)을 추가(追加)한다.

상용 위성탑재카메라를 이용한 지표면의 고해상도 영상획득은 1990년대부터 세계 각국에서 많은 노력과 투자를 하고 있다. 미국은 이미 해상도 1m급의 IKONOS, Orbview 및 Quickbird 등을 운용하고 있으며 최근에는 해상도 0.5m급 이하의 위성탑재 카메라를 개발하고 있는 것으로 알려졌다. 러시아, 프랑스, 이스라엘, 일본 등도 1m급 탑재카메라를 개발 중이거나 운용중이며 우리나라도 다목적 실용위성 시리즈의 탑재카메라 개발을 통해 고해상도 위성 카메라를 운용 및 개발 중이다. 이러한 개발동향에 따라 고해상도 위성카메라의 광학부품과 구조부품에 대한 기술적 연구와 개발에도 많은 노력이 이루어지고 있는데, 국내에서도 향후 계속되는 국가의 위성탑재카메라 개발계획에 따라 요구되는 핵심 광구조 부품 개발을 위해 대구경 광학 부품이나 구조물에 대해서 단계적인 국내개발을 시작하고 있다. 우선적으로 한국항공우주연구원과 한국표준과학연구원은 연구원간 협력프로그램으로 대구경 우주급 반사경조립체에 대한 국내개발을 진행하고 있으며 우주환경에서의 광학시험에 필요한 관련 시설을 구축하고 있으므로 국내의 위성관련 광구조부품 개발 기술도 획기적으로 향상될 것으로 기대된다.

A study on quinolone antibacterial (pefloxacin methanesulfonate) was performed to use for the drug of fisheries. Petloxacin was proved excellent in antibacterial activity and resistance against fish pathogens when compared with the existing antibacterials. And any side effect was not observed during the period of indicated use. An outline of MIC(Minimal Inhibitory Concentration) was $1.6{\sim}6.4{\mu}g/ml$, $TLm_{48h}$ value were 380~420 ppm in Israeli carp(Cyprinus caprio) and 2100~2300 ppm in flounder(Paralichthys olivaceus). The residual time of fish body was less than 15 days. So we can treat some bacterial disease of fish by the dosage of 100 g/day/ton of fish body weight for 3 days and pefloxacin is thought to be used effectively and widely against most bacterial fish pathogens.

Most of weapon purchasing countries in the world are using offset trade as an important negotiation means of foreign trade. In particular, Japan and Israel have obtained good results in the new projects and finding a new market for the long run through the offset trade. On the other hand, the USA holds much weight in the aspect of Republic of Korea's record of offset trade performance. However, compared with the record, her achievement known concretely has been evaluated insufficiently. Therefore, we suggest the improvement plans of the offset trade drive systems in this study. So that we analyze foreign countries' priority by offset trade type against the USA, the American offset trade object and priority and the case study of offset trade's post valuation plan. Moreover, we extract management problems of assets and technical materials obtained through the offset trade.

The size of state in Korea is like Israel, this country's venture capital is ruled by government. This venture capital's character is below: the concentration on research of venturer affect positively at qualify of products, This paper lies with venture capital's risk character & performance. The results show that Korean venture capitals have lager unsystematic risk than systematic risk, which implies they specialize in specific business and/or regional areas instead of diversification. The Sharpe measure reveals that the performances of Korean venture capitals are very low relative to even the market portfolio(Kospi) and Kosdaq.

We reported an outbreak of Aeromonas (A.) veronii responsible for ulcerative dermatitis in Israeli carp (Cyprinus carpio). The major clinical signs were darkening body, abdominal extension, exophthalmos and severe ulcerative necrosis in the skin. The necropsy showed yellowish ascites, necrosis in liver and enlargement of kidney and spleen in the morbid fish. In blood agar for culturing bacteria, three different colonies were identified as A. veronii, Plesimonas shigelloides and Shewanella putrefaciens by phylogenetic identification using 16S rRNA or gyrB gene sequences. A. veronii was the most dominant species among them and was resistant to ampicillin, nalidixic acid and oxytetracycline.

This study was conducted to research the differences in food ingredients in the ancient Israelite period in the books of Moses, including the books of Geneses through Deuteronomy, in the Old Testament written during B.C $1446{\sim}1406$. The books introduced various foods in daily life, such as seven kinds of fruits and nuts, thirteen kinds of vegetables and grains, twelve kinds of meats, six kinds of breads and cookies, five kinds of drinks, thirteen kinds of spices, and five kinds of processed foods like butter and oil. The foods were sharply distinguished between the clean (able to eat) and the unclean (unable to eat) in the aspect of food culture. For example, foods with blood were not allowed to be eaten. At that time, bread was a staple food in Israel. There were already standard recipes for baking cookies, and appliances such as frying pans and ovens to bake bread were available. Most of the recipes in the books were the same as modern recipes, especially for wine, grape juice and raisins. Also it seems there were various spices already in use at that time, as well as processed foods made from milk.

The Cyberspace of the Republic of Korea Army is continuously threatened by enemies. Means for responding to such cyber threats are ultimately Military information security professional personnel. Currently, however, there are only a handful of advanced information security professional persons in Republic of Korea Army, and a lack of systematic training is inadequate. Therefore, in this thesis, we surveyed the information security professional human resource policies of USA, UK, Israel, and Japan. In addition, the policy to train professional human resources specialized in defense cyber security, we proposed training of specialist talent of 4 steps and medium and long term plan, step-by-step training system sizing, introduction of certification system.

The development of explosive detection technology in a security environment and fear of terrorism at homeland and abroad has been one of the most important issues. Moreover, research works on the explosive detection are highly required to achieve domestic production technology due to the implementation of aviation security performance certification system. Traditionally, explosives are detected by using classical chemical analyses. However, in the view of high sensitivity, rapid analysis, miniaturization and portability electrochemical methods are considered as promising. Most of electrochemical explosive detection technologies are developed in USA, China, Israel, etc. This review highlights the principle and research trend of electrochemical explosive detection technologies carried out overseas in addition to the research direction for future exploration.

A lot of research has been done on pipe climbing robots to investigate the aging pipe structures of nuclear power plants and petrochemical plants. Nevertheless, most of the research on pipe climbing robots focused on the structural design and foundational motion control of pipe climbing robots. So, For the operator to control the pipe climbing robot, it has many difficulties to climb the pipe and avoid obstacles by manual operation. In this paper, propose an algorithm that recognizes obstacle by using camera images of pipe climbing robots, estimates the distance between pipe climbing robots and obstacles, and determines the position where pipe climbing robots can catch pipes to avoid obstacles between pipes.
