The objectives of this study were to estimate genetic parameters for 10 linear conformation traits and final score in Hanwoo cows. A total of 53,277 records for type traits of Hanwoo cows were collected from 2008 to 2012 from Korea Animal Improvement Association. Ten linear traits studied were stature, body length, chest depth, body rump angle, rump length, pin bone width, udder volume, foot angle, rear legs side view, and rear legs rear view. The model included the fixed effects of herd-year-classifier, age at measurement and age after calving, the random animal additive genetic effect and residual effect. Heritability estimates for linear type traits were ranged from 0.003 for rear legs side view to 0.213 for final score. Genetic correlations among linear type traits were ranged from -0.068 (for rear legs side view and rear legs rear view) to 0.982 (for body length and rump length). The final score was found to be in a strongest genetic correlation with rear legs rear view (0.947), followed by pin bone width (0.918), body length (0.887), rump length (0.883), chest depth (0.883), udder volume (0.811), stature (0.802), rump angle (0.637), foot angle (0.519) and rear legs side view (0.176). Corresponding phenotypic correlations for pairs of linear type traits were mostly similar in direction, but smaller than the genetic correlations.

The objective of this study was to estimate genetic parameters on days to 90 kg body weight and ultrasound measured traits (back fat thickness, eye muscle area, retail cut percentage) and predict genetic progress when the weights for selection on the paternal traits of Duroc, which can be incorporated into sire line selection indexes. A simulation program, ZPLAN+, was used for the simulation. Genetic parameters of days to 90 kg body weight (D90KG), back fat thickness (BFT), eye muscle area (EMA) and retail cut percentage (RCP) used in the simulation were estimated from 27,972 heads of farm tested Duroc pigs from 2005 to July, 2012. Parameters of simulation used genetic parameters with parturition rates, ratios of test pigs and replacement rates that were dependent on selection protocols of simulated farms. Different weights of selection for traits of days to 90 kg and backfat thickness were compared. Estimates of heritability were 0.406, 0.355, 0.159 and 0.379 for D90KG, BFT, EMA and RCP, respectively. Genetic correlation of D90KG with BFT, EMA and RCP were –0.043, 0.049 and 0.021, respectively. Genetic correlation of BFT with EMA and RCP were –0.394 and –0.937. And genetic correlation between EMA with RCP were 0.524. Simulation result showed that index weight of 3:1 on D90KG and BFT was effective to shorten days to 90 kg without any significant changes in backfat thickness. Generally the genetic changes were greater as parturition rate and ratios of test pigs increased. Increase in replacement rate had a small effect on genetic changes in negative way. Thus, we recommend that index weight of 3:1 on days to 90 kg and backfat thickness could be utilized for sire line selection.

The objective of this study was to determine the effect of the MC1R genotypes of the Chikso (Korean brindle cattle) sires on the coat colors of their offspring. In this study, 15 Chikso sires with known MC1R genotypes were used for breeding in the Gangwon Province Livestock Research Center, the Chungbuk Institute of Livestock and Veterinary Research, and the Livestock Experiment Station, Jeonbuk Institute of Livestock and Veterinary Research from either 2011 or 2012 to 2013. There were 6 sires with E+E+ genotypes and 9 sires with E+e genotypes, and their coat colors were all whole brindle (more than 50 of the body). Among the 90 calves produced in 2011∼2013 or 2012∼2013 from the 15 sires, 50 (55.6%) of them were females and 40 (44.4%) of them were males. Coat colors of the offspring were determined when they reached over 6 months of age. Calves with whole brindle, part brindle, brown and black coat colors were 42 (48.3%), 11 (12.6%), 18 (20.7%) and 16 (18.4%), respectively. Ratio of calves with whole brindle coat color was higher than any other coat colors. Among the offspring with whole brindle color, 20 (41.7%) calves were female and 22 (51.3%) calves were male. By determining the MC1R genotypes of the dams and calves in this study along the family lines, and investigating other genes that may be involved in the coat colors of the Chikso, better breeding system may be established to increase the brindle coat color appearance in the future.

이 연구는 선원의 의료와 건강실태 현황을 설문조사를 통하여 선원에 대한 의료지원 및 건강증진을 위하여 개선해야 할 점을 찾고 의료사각지대로 되어 있는 선내 의료 및 건강관리 여건을 개선하기 위한 제도개선 방향을 제안하는 것을 목적으로 한다. 이 논문에서 제시한 선원건강증진을 위한 정책 추진과제를 실천하기 위해서는 선원법 등의 법적 뒷받침이 필요하다. 이를 위하여 추진하여야 할 제도개선방향은 다음과 같다.첫째, 선내응급의료지원의 질적 향상을 추진하여야 한다. 이를 위하여 무선전화에 의한 음성 정보에 의존하여 응급의료지원을 하고 있는 한계를 극복하여야 하며, 의료지원을 하는 의사가 응급선원의 건강상태를 파악할 수 있도록 건강측정장비를 선박에 비치할 것을 의무화하는 등 제도를 강화해 나가야 할 것이다. 둘째, 응급 시만 의료지원을 하는 현행 제도를 개선하여, 응급 시 뿐만 아니라 평상시에도 의료지원을 할 수 있도록 제도적 개선이 필요하다. 이를 위해서는 원격의료에 대한 현행 법제에 대한 개선이 필요하다. 선박 등 의료기관 이용이 제한되어 있는 곳에 대해서는 의료 수요자가 절실하게 요청하고 있는 원격의료의 허용을 전향적으로 검토하여야 할 것이다.셋째, 최근 발달하고 있는 최신 응급의료장비의 선내비치와 더불어 각종 해상 응급상황에 맞는 의약품을 갖출 수 있도록 특히, 신종 전염병의 발병 시 지체없이 필요한 예방약품을 갖출 수 있도록 제도적 정비가 필요하다. 이를 위해서는 선원법 시행규칙 제52조에 대한 정비와 선내에 비치할 의약품과 의료장비 비치기준에 대한 주기적인 검토제도가 마련되어야 한다.넷째, 의료관리자 제도에 대한 개선방향으로는 선원법 제85조 및 제87조를 개정하여 선박소유자가 선장 또는 1등항해사 중에서 의료관리자 또는 응급처치담당자를 지정하도록 제도적 보완을 할 필요가 있다. 또한 선원에 대한 원격의료의 효과를 제고하기 위해서는 의료관리자에게 원격의료 상황에서 원격지의사를 보조하여 원만한 의료행위가 가능하도록 하는 제도의 마련도 추진되어야 할 것이다.다섯째, 선원의 건강문제에 대하여 상병 후 치료 중심에서 발병 예방 중심으로 진화할 수 있도록 선박에 비치할 건강측정장비를 개발하고 평소에 선원의 건강상태를 측정하여 건강상태를 확인하는 예방적 선원건강관리제도의 도입이 필요하다. 이를 실현하기 위한 효과적인 방안은 선원건강증진센터를 설치․운영하는 것이다.

전 세계적으로 ‘지구환경 보호운동’과 웰빙 삶이 확산되면서 환경과 인체에 부정적인 영향을 미치고 있고, 특히 합성섬유의 주원료인 원유가 멀지 않은 장래에 고갈될 것을 예상하고 있으며, 이에 대한 대안으로 새로운 천연섬유 소재의 창출에 대한 연구가 활발하게 진행되고 있다. 따라서 본 연구는 천연섬유의 주산지가 될 수 있는 자연 환경적 요소를 갖추고있는 캄보디아 천연섬유 작물 현황을 조사하여 추후 한국 농산업체의 천연섬유 생산에 대한 투자를 대비한 정보를 제공하고자 조사 연구하였던 바 결과를 요약하면 다음과 같다. 1. 현재 캄보디아의 천연섬유산업은 소규모로 아직 초기 단계에 있으며, 조사된 황마, 부레옥잠 등 열대식물도 있지만, 왕골, 갈대, 목화 등 온대지역에 자생하는 천연섬유 등 12가지 작물이 대표적인 천연섬유 작물로 조사되었다. 2. 누에를 이용한 실크산업은 캄보디아의 저렴한 노동임금으로 부가가치 창출이 쉬운 산업으로 캄보디아 정부에서 활성화 길을 모색하고 있으나, 기술력 향상을 위한 인력양성이 가장 큰 문제점으로 대두되고 있다. 3. 목화를 이용한 천연섬유 생산은 대단위 노동집약적 산업으로 수출활로의 전망은 좋으나 주로 북부지역이 주 생산지로 인구밀도가 적은 농촌지역에서 활성화시키는데 한계점이 있는것으로 나타났다. 4. 캄보디아의 열대성기후와 정부의 지원, 세계의 천연섬유산업의 트렌드와 더불어 천연섬유 분야의 전문가 양성과 해외 투자자유치, 섬유생산기술 발전 등을 동반한다면 캄보디아는 새로운 천연섬유생산기지로 발전 가능성이 있는 것으로 조사되었다.

The purpose of this study is to investigate the errors concerning V-ing forms in Korean college freshmen’s English essays in order to provide some guidelines for teaching the forms effectively. The data for this study were retrieved from a learner corpus consisting of 815 essays written by Korean college freshmen. A total of 3,843 words were found in the form of V-ing, which were categorized according to their roles as follows: (a) present participles (1,235 tokens), (b) gerunds (2,591 tokens), and (c) unclear cases (17 tokens). Of the 3,843 forms of V-ing, a total of 292 tokens were classified as erroneous, 137 of which were participle-related errors and 138 gerundrelated errors. The most frequently occurring errors under the categories of present participles and gerunds were the use of a present particle without a main verb (64.2%) (e.g. I *looking for the meaning of the building’s name) and to-infinitive related errors (66.7%) (e.g. Therefore, we try to *changing our college’s image), respectively. Pedagogical suggestions based on the findings of the study are also provided at the end.

Preservation, distribution and share of regional genetic resources are one of the hot topics of international debates. Korean government under National Institute of Animal Science (NIAS) supervision made a law that initiated national management system of livestock genetic resources in agriculture and fishery (July, 2012). NIAS preserve domestic livestock genetic sources of Chikso (Korean brindle cattle), Heugu (Korea black cattle), native pig and native chicken under the strategies of multiple place guardians to keep these minor animals from getting extinct through various reasons. A total of around 3,300 animals are under protection currently. Around 70,000 germ cells of Chikso, Heugu, native goat, etc, are stored by cryopreservation method. Moreover,around 30,000 samples of whole blood and DNA are stored in deep freezers. NIAS also constructed Animal Genetic Resource Information Management System (AGRIMS) and stored information including the phenotypes and genotypes of livestock genetic resources. We also have built companionships with nine provincial livestock institutes and two universities regarding rare livestock animal management since 2008. These companion organizations have around 16,000 animals of 11 breeds in their custody. Internationally, we keep on registering these breeds on FAO and Domestic Animal Diversity Information System (DAD-IS) database systems. Recently we updated registration of 24 breeds of six species such as Chikso, Chookjin Chamdon, Ginkkoridak, Jindo, etc.

The objective of this study was to identify the effects of various environmental effects associated with performance testing results in pig population of domestic pig breeding farms. Performance test data collected from 2,000 to 2,010 were a total of 265,901 heads. By breeds, data consisted of Duroc, Landrace and Yorkshire. Environmental factors considered in models were breed, sex, farm, year of test, season of test, and parity. Broad range of age at testing day averaged at 155 days of age were grouped as A (up to 140 days) B (141~150 days), C (151~160 days), D (161~170 days), and E (greater than 170 days). Traits analyzed were ADG, days to 90 ㎏, end weight (body weight at the test day), rib eye area, back fat thickness. Age group effects were all significant for all the traits studied (p<0.05). As ages at test day get greater, ADG, days to 90 ㎏ and end weight tended to be greater while ultrasound measures of rib eye area and back fat thickness tended to be less. This would be the results of linear age adjustments on ultrasound measures, that caused overestimation in younger age groups and underestimation in older age groups than in average age group (C). This was evidenced by looking at ultrasound measures before linear age adjustments were applied. We conclude that, for more accurate performance testing, testing within guided age interval should be abided. And further researches should be made on biologically justifiable methods of age adjustments especially for ultrasound measures.

본 연구는 2004년부터 2011년까지 한국종축개량협회에서 듀록 품종에 대하여 수집된 40,657두의 검정기록 및 이들과 혈연관계가 있는 47,974의 가계혈통정보를 이용하여 산육형질에 대한 유전모수를 알아보고자 연구를 실시하였다. 듀록의 산육형질에 대한 유전모수 추정은 고정효과로써 성, 동기우 그룹, 산차 및 검정종료시 개체나이(공변이), 임의효과로써 개체의 상가적 유전효과 및 잔차효과를 포함한 혼합모형방정식을 구성하였으며, 분석은 리눅스 기반의 REMLf90 프로그램을 이용하여 다형질 분석을 실시하였다. 유전력은 90 kg 도달일령, 일당증체량, 등지방두께 및 등심단면적에서 각각 0.334, 0.340, 0.335 및 0.200로 추정되었다. 또한 형질간 유전상관의 결과를 살펴보면, 90 kg 도달일령과 일당증체량, 등지방두께 및 등심단면적에서의 유전상관이 각각 -0.992, 0.130, 0.358, 일당증체량과 등지방두께, 등심단면적에서의 유전상관은 각각 -0.142, -0.361, 등지방두께와 등심단면적간에는 -0.243로 나타났다. 90 kg 도달일령과 일당증체량간에 고도의 부의 상관을 보였으며, 90 kg 도달일령과 등지방두께, 등심단면적은 중저도의 정의 상관을 보였으며, 나머지 형질간에는 부의 상관을 보였다. 듀록 선발시 산육형질간 유전상관을 고려한 개량목표 설정이 필요할 것으로 사료된다.

본 논문은 한우 거세우의 각 월령별 체중과 18개월 체척, 도체형질에 대하여 출생지, 후대검정차수, 측 정일령, 도축일, 도축일령등의 환경효과가 영향을 미치는지 알아 보기위하여 실시하였다. 이 연구에 사용 된 자료는 농협중앙회 한우개량사업소에서 2004년부터 2008년까지 후대 검정한 38차에서 47차까지의 거세우 1,838두의 성장형질과 도체형질 자료를 이용하였고, 성장형질은 18개월령 체척자료와 6개월, 12개 월, 18개월, 24개월 체중을, 도체형질은 24개월령 도축성적을 이용하였다. 각 형질에 대한 환경효과 분석을 위해 각 월령별 체중에 대해서는 고정효과를 출생지, 후대검정차수로 하였고 공변량을 측정일령으로 하였다. 도체형질은 도축일을 고정효과로 도축일령을 공변량으로 하였다. 18개월 체척의 경우는 고정효과를 출생지, 후대검정차수로 하였고, 공변량을 18개월 체척측정일령으로 하였다. 분석결과 24개월 체중에서는 출생지 효과가 유의성이 낮은 것으로 나타났다. 도체형질인 도체중, 등심단면적, 육량지수, 등지방 두께는 도축일에 따른 유의적인 차이가 존재하는 것으로 나타났지만 도축일령에 따른 유의적인 차이는 없었다. 근내지방도에 대해서는 도축일령과 도축일 모두 영향을 미치는 것으로 나타났다. 또한 체척형질은 흉심, 고장폭, 흉위에서 출생지 효과는 영향이 없는 것으로 나타났다. 따라서 본 연구결과는 한우 유전평가 모형 설정 시 활용 가능한 것으로 예상된다.
