신성철,정구용,정의룡,Shin, Sung-Chul,Chung, Ku-Young,Chung, Eui-Ryong 한국축산식품학회 2007 한국축산식품학회지 Vol.27 No.3

본 연구는 포유류의 Y-염색체상에 존재하는 SRY 및 ZFY의 웅성 특이적 성 결정 유전자를 이용하는 PCR 기법으로 쇠고기 성판별 기술을 개발하고자 수행하였다. 성 결정 유전자 영역의 특정 염기서열을 포함하는 primer를 각각 설계 합성하고 이들 primer를 이용하여 PCR증폭을 실시한 다음, 각각의 증폭산물을 1.5% agarose gel에 전기영동하여 웅성 특이적 DNA band의 증폭여부를 확인하였다. SRY 유전자에서 웅성개체 쇠고기는 1,348 bp 크기의 단편을 가진 DNA band가 검출되었으나, 자성개체의 경우 DNA band가 전혀 검출되지 않은 것을 확인 할 수 있었다. 또한, ZFY 유전자에서 웅성개체의 쇠고기는 979 bp 크기의 단편을 가진 DNA band가 모두 검출되었으나, 자성개체의 쇠고기에서는 역시 DNA band가 전혀 검출되지 않았다. 즉, SRY 및 ZFY 유전자는 모두 숫소에서 유래한 쇠고기에서 웅성 특이적인 DNA band가 정확히 검출된 반면 암소에서 유래한 쇠고기에서는 웅성 특이적 DNA band가 전혀 검출되지 않았다. 또한 쇠고기 성 감별법을 도축 후 가공 유통판매단계에 실제 활용 가능성을 검증하고자 시중에 유통되고 있는 등심 및 갈비 포장육 350시료를 무작위 추출하여 성 판별을 실시한 결과 숫소가 252시료(72%) 그리고 암소가 98두(28%)로 조사되었다. 따라서 본 연구에서 개발한 SRY 또는 ZFY의 웅성 특이적 성 결정 유전자를 이용하는 쇠고기 성 감별기술은 생산단계는 물론 도축 후 가공 유통 판매되고 있는 모든 쇠고기의 암수 성감별을 위한 유용한 DNA 표지인자로 활용할 수 있을 것으로 기대된다. The objective of this study was to develop a rapid and reliable method for the sex determination of beef using the PCR(polymerase chain reaction) technique. We have used two bovine sex determining genes, SRY and ZFY, on the Y-chromosome to identify the sex of Hanwoo and Holstein beet. We attempted to amplify 1,348 bp and 979 bp fragments from male and female genomic DNA corresponding to the SRY and ZFY genes, respectively, using male specific primers. The amplified PCR products were separated by electrophoresis in a 1.5% agarose gel to detect a male specific DNA band. When DNA from male beef was amplified with primers specific for the SRY gene, a DNA band of 1,348 bp was present in all of the male samples, but absent from all of the female samples. Also, when DNA from male beef was amplified with primers specific for the ZFY gene, a DNA band of 979 bp was observed in all of the male samples, but absent from all female samples. In conclusion, the bovine SRY and ZFY genes are typically found only in male beef. For the practical application of this method for the sexing of commercial beef at the processing and marketing stages after slaughter. a total of 350 beef samples collected randomly from local markets were analyzed for sex determination. The proportions of male and female samples were 252 (72%) and 98 (28%), respectively. Therefore. the SRY and ZFY genes. which are specific for the Y-chromosome, may be useful sex-diagnostic DNA markers to distinguish male meat from female meat.

신성철,박영만,Shin, Seoung-Chul,Park, Young-Man 한국시뮬레이션학회 2010 한국시뮬레이션학회 논문지 Vol.19 No.2

In the anti-submarine warfare, a search using HMS is used as a basic strategy. The importance of HMS operation strategy is increasing, but it is hard to develop effective anti-submarine search strategy due to reciprocal actions among sea environments, search patterns, sonar operational tactics, anti-submarine search strategy, etc. In this research, a simulator was invented so as to analyze anti-submarine search patterns used when an HMS-carrying ship searches for submarine in various anti-submarine search environments. The simulator reflects various factors that influence anti-submarine search, and with consideration of search patterns of anti-submarine ships as well as evasive movement of submarines, it can simulate various anti-submarine search operations such as a collaborative anti-submarine operation by a single or multiple forces. Also, the simulator will contribute to developing and improving systematic and efficient HMS operational tactics in anti-submarine warfare.

The Navy is in the process of developing a sonar-operation strategy to increase the effectiveness of underwater target searching capability. HMS is the basic strategy to detect underwater targets. The advantages of HMS is that, it has a short preparation time to operate and can be always used regardless of sea conditions and weather. However, it is difficult to effectively detect underwater targets due to the interaction between marine environments and sonar-operations. During the research, the effectiveness of the HMS system's underwater target searching capability was analyzed by integrating various search and defense patterns, and environment conditions into the simulation. In the simulation the ship search an evasive target within a set region. The simulation presented results for an effective searching and defense methods of underwater targets. These research results can be used as foundation for advancing and improving the sonar operational tactics.

申星澈(Sung Chul Shin) 한국인구학회 1986 한국인구학 Vol.9 No.2

This study was carried out to calculate working life expectancy and its potential gains according to the degree of reduction in the specific causes of death. It sought to ascertain what potential gains in labor force longevity might be reasonably achieved through efforts to reduce mortality from injuries and poisoning, diseases of circulatory system, neoplasms and the other causes of death. The data were drawn from the three sources such as "The 1982 Causes of Death Statistics," "Abridged Life Table for Korea 1978~'79" and "The 1982 Annual Report of Economically Active Population" issued by Economic Planning Board. Analytical tools used in this study were the cause-deleted life table and the Wolfbein Wool's working life table method. Partial life expectancy was adopted as an index of this study, This application will be widely used as a good demographic tool for analyzing the dynamics of labor force and causes of death. Some of the findings are summerized as follows. 1. Partial lite expectancies from initial age 15, 25, and 45 respectively to terminal age 65 are 44.86, 35.59 and 17.41 years in life expectancy itself, 37.08, 32.83 and 15.21 years in working life expectancy, 7.78, 2.76 and 2.20 years in inactive life years. 2. Potential gains in working expectancy from initial age 15, 25 and 45 to terminal age 65 by the complete elimination of the specific causes of death are 1.36, 0.94 and 0.27 years in injuries and poisoning, 0.88, 0.83 and 0.54 years in diseases of circulatory system, 0.56, 0.54 and 0.37 years in neoplasms, 1.13, 1.02 and 0.58 years in the other causes of death. The relationship between degree of reduction in causes of death and potential gains in working life years is in direct proportion. The prime orders of reduction effectiveness in age groups by the causes of death are injuries and poisoning in age 15-24, the other causes of death in age 25-49 and diseases of circulatory system in age 50 and over. 3. If it were possible to reduce 25%, 50% and 75% in mortality condition 1978~'79, the average length of working life would be 38.08, 39.13 and 40.17 years in age 15, and 33.68, 34.57 and 35.44 years in age 25, and 15.67, 16.14 and 16.63 years in age 45.

This study was intended to analyze real situations of private certificates related to school violence registered with Korean Private Information Service and, on the basis of such analysis, it found problems in private certificate system related to school violence and proposed alternatives. At the present time, the total number of private certificates related to school violence registered with Korean Private Information Service was found to be 239, and there was no authorized private certificate, all of such certificates being private certificates registered. It was found the problems in private certificates related to school violence arose: first, in the identity and expertise of relevant private certificate registration agencies; second, in public confidence of relevant certificates; third, in job performance of the persons having relevant certificates; fourth, in the process of qualification examination; and lastly, in follow-up management. As alternatives to these problems, followings can be mentioned. First, it is necessary to ensure that, in case of a certificate which is not actually used or utilized, registration of such a certificate may be abrogated. Second, giving a regular education to related persons is needed so that the private certificates related to school violence may be registered as authorized private certificates and secure public confidence. Third, it is required that a process for qualification examination must be reinforced in order to enhance expertise of relevant agencies and it is required to instruct relevant agencies to compulsorily make public a process of obtaining qualification so that consumers can know information of relevant certificates. Lastly, an education for the agencies of managing certificates needs to be given so that such agencies may operate management of certificates systematically and specially.
