The INRA124 is a bovine Y-chromosomal specific microsatellite locus that has been revealed a polymorphism. This locus has two alleles. The 132 bp allele is specific to cattle (humpless) of taurine origin and the 130 bp allele is specific to cattle (humped) of indicine origin. A total 822 males of 20 breeds or populations; North Eastern Asian breeds (Hanwoo, Korean Black cattle, Chik-so, CBK, Japanese Black cattle, Japanese Brown cattle, Yanbian cattle), Chinese yellow cattle (Luxi cattle, Nanyang cattle), European origin (Angus, Hereford, Charolais, Simmental, Brown swiss, Holstein, Limousin), African origin (Kavirondo zebu, White Fulani, crossbreed of N'Dama and Boran), Indian origin (Sahiwal) were characterized the distribution of alleles using INRA124 locus. Any individuals of European, Japanese origins and Hanwoo were not detected 130 bp allele, Bos indicus specific allele. Bos indicus breeds of Indian and African origins were not detected 132 bp allele, Bos taurus specific allele. CBK population that the crossbreed of Hanwoo, Brahman and Charolais showed the frequency of 0.19 in indicine specific allele. The breeds of Chinese mainland, Luxi and Nanyang cattle were detected 0.46 and 0.29 frequencies in indicine specific allele, respectively. These results suggest that Korean cattle, Hanwoo, had not been originated from a crossbred between Bos primigenius in Europe and Bos indicus in India.

1990년대까지 정부출연연구기관은 우리나라의 과학기술을 선도하는 연구개발의 한 주체로서 중요한 역할을 담당해 왔으나, 최근 급속히 변화되고 있는 경제 사회 및 기술적 환경 속에서 정부출연연구기관의 역할 및 위상에 대한 문제점들이 선행연구에서 지적되고 있다. 현재 정부출연연구기관은 각자의 역할 및 위상에 따라 다양한 형태로 정부R&D 과제들을 수행하고 있는데, 이 중 특정 기술분야 및 기술단계에 집중된 과제를 수행하는 출연연구기관이 있는 반면, 다양한 기술분야 및 기술단계의 과제를 수행하는 출연연구기관도 있다. 한 분야에 집중된 과제의 수행은 해당 기술분야의 노하우(know-how), 지식, 기술을 집중적으로 축적하고 해당 분야에 대한 전문성을 제고함으로써 높은 논문성과를 이끌어 낼 수 있을 것이다. 그러나 한 기관에서 다양한 분야의 과제를 수행하는 것 또한 여러 분야의 지식이나 기술을 획득 보유하게 함으로써 다양하고 창의적인 연구를 가능하게 하고, 지식 및 기술 간 융합에 따른 시너지 효과를 통해 높은 논문성과를 도출하는데 기여할 수 있을 것이다. 이처럼 판단하는 시각에 따라 기관이 수행하는 과제의 집중화 정도가 논문성과에 미치는 영향이 상반되게 해석되는 상황에서, 본 연구를 통해 실제 우리나라의 출연연구기관의 경우 그 영향이 어떻게 나타나는지 실증분석을 통해 살펴보고자 한다. 이에 따라 논문을 주요 연구성과로 하는 기초기술연구회 소속 정부출연연구기관을 대상으로 정부출연연구기관이 수행하는 과제특성의 집중화 정도에 따라 집단을 분류하고, 이들 집단 간의 논문성과 차이를 비교 분석함으로써, 출연연구기관 특성에 따른 차별화된 정책 운영에 대한 시사점을 제시하고자 한다.

According to the report from OECD, 80% of world trade quantity was influenced by standard, 50% of EU trade demand certification of forced standard. This leads to develop standard connected with R&D in most country and company worldwide. Recently, Technical standards have advantage of reduction of production cost and market dominating power. Standardization of construction technology has very important role that ouput of R&D refer to KS, national construction standards and it activates in the market. However, domestic construction research related to effectiveness of standadization fall short of expectation in comparison with manufacturing industry. This study present criteria that can analyze the performance and effectiveness in construction R&D project connected with standardization. And it applied domestic R&D cases (finished from 2000 to 2009), analyzes ouput of standadization and economic effect to verify the value of construcion technology standardization.

Three Pinus densiflora populations as shown in location map (Fig. 1) were studied in 1977. These succeed the population numbers 10, 11 and 12 after the preceeding populations. Following the previous study methods, 20 trees were chosen from each population and the morphological characteristics such as tree forms, branching habit, needle and wood properties were investigated. The results are summerized as follows; 1. The mean stand ages were ranged from 40 to 45. The growth performances of trees of population 10 and 11 was similar, but 12 seemed to be inferior more or less. 2. The ratios of clear bole length was 0.53 in population 12 as the highest but 0.43 for population 10 as the lowest. 3. The population 12 was considered to be a stand of the coarser branching habit having the crown index (The maximum crown diameter/the crown length) 1.65 though the mean branching angle indicates almost horizontal. 4. The differences were observed in the clear bole length ratios and crown-indices between populations as shown in Fig. 3 and 4. 5. No inter-population differences in serration density of needle was shown but significant inter and intra-population and individual differences (within population) in number of stomata rows and resin duct. 6. Population 12 shown 0.119 of resin duct index as the maximum. 7. The pattern of diameter growth, analyses based on the width of 10-year-ring segment unit (for example, the 1st segment denotes the width between pith center and 10th year ring and the 2nd one is from 11th to 20th year ring and so on.), was alike among populations as shown in Fig. 9. 8. No significant differences between population in mean summer wood percentages as well as in wood specific gravity was observed. The values of wood specific gravity were increased with the increase of ages in population 10 and 11 however vice versa in population 12. 9. The fiber length was increased with the increase of age but no differences between populations as shown in Fig. 12.

Complement of test standard, evaluation methods and models are needed to improve national competitiveness and to exchange superior genetic resources through the comparison of genetic evaluation score among nations in dairy cattle. Therefore, this study was conducted for the application of international standard to Korea considering domestic circumstance by changing linear-classification test score system of 50 classes which is currently used in Korea to system of 9 classes which is used in advanced nations of dairy. 15,230 of holstein cow linear type records with first parity records for the fifteen linear type and one total score from 2001 to 2006 and pedigree data which were collected by the Korean Animal Improvement Association were used in this study. Population classified by 9 levels was more normal distributed than 50 levels. Correlation coefficients between 50 and 9 score system showed over 0.98 by each classification scheme. Therefore, the 50 point system can be substituted with 9 point system due to their highly positive correlation. However, scores in all traits were still very contingent on classifier under the 9 point system (p<0.001), and F values between foot angle and front teat attachment showed high fluctuation depending on classifier. It means that subjective opinions of classifier would influence on linear type score as ever even if class scheme transformed to system of 9 class. Therefore, the relevance of transformation to the 9 point system should be assessed after analyses about various environmental factors.

Alternative initiation codon(AlC) has been reported in the mitochondrial genes in various mammalian species. We investigated the AlC of mitochondrial NADH dehydrogenase 2 gene(rntDNA ND2) in five pig breeds. Two kinds of initiation codons(ATA/ATf) showing different frequencies among tested pig breeds were used. While all Large White pigs had ATA as an initiator methionine codon, all Landrace pigs had ATf. The other breeds(Berkshire, Duroc and Hampshire) had both initiation codons with the ATA frequencies, 91.9, 21.3 and 60.00/0, respectively. In the previous reports, all Chinese indigenous pig breeds were identified to have unique initiation codon ATA. Although the effect of Ale on the translation of mtDNA ND2 has not been studied in this study, AlC patterns in mtDNA ND2 will contribute to the maternity test using molecular markers in pig breeding.

본 연구는 Kingdon의 다중흐름모형(MSF: Multiple Stream Framework)을 통하여 정부연구개발예산 중 미래성장동력 부문에 대한 예산결정 과정을 살펴보았다. 연구 대상은 대통령 의지로 의제가 발기된 정책의제 국가전략프로젝트이며 비합리적 의사결정에 대한 견제수단으로 활용되는 예비타당성조사가 예산의 결정단계로 이어지는 일련의 과정을 살펴보았다. 연구의의는 3개 흐름에서 행해지는 비합리적 의사결정 케이스를 확인하고, 정부 R&D 사업의 예산결정과정에서 온-오프 스위치 역할을 하고 있는 게이트 키퍼(gate keeper)인 사업 평가자(PM), 구체적 사업계획안을 만드는 부처의 사업기획자, 그리고 자문역할을 하는 전문가집단을 정책혁신가로 바라볼 수 있다는 의의를 발견했다. 공공부문의 정책혁신가는 사업을 기획한 부처와 같이 자기(부처)이익을 추구하지는 않지만 공공가치를 추구하는 독립적인 위치에 있었고, 어느 일면에는 과학기술분야의 성장과 발전을 바라고 있었다. 다시 말해, 연구는 정책혁신가라는 존재가 특정한 개인 또는 집단일 뿐만 아니라 2개 집단 이상의 복수의 정책혁신가가 있을 수 있는 가능성을 확인하였다. 특히, 예비타당성조사에서 PM이 흐름 간의 중개를 상향적 직접적으로 수행하지 않지만, 하향적으로 사업기획자 등 주체들 간 의견을 조정하고 합의를 이끌어 내는 모습은 중요 활동을 하고 있음이 확인되었다. 연구는 정책혁신가의 새로운 형태를 발견하였지만, 정책결정의 전 주기가 아닌 정부예산 이후 국회예산이라는 특정 시기를 대상으로 하였는데, 분석 과정에서 예산과 시간의 제약으로 사업기획을 담당했던 부처 및 기재부공무원, 해당기술 분야 연구자, 국회 관계자 등 관련 주체들의 견해를 고루 담아내지 못한 아쉬움이 있다. 향후 다양한 참여자들의 의견을 수렴할 수 있다면 정책 결정 과정에 정책혁신가의 다층적(Multiple) 존재 여부와 특성을 면밀히 들여다 볼 수 있을 것이다.

As a successive work of the variation studies of natural Pinus densiflora stands, some characteristics of individual trees of the three natural populations selected from the Kwang-won Province, the middle-east part of Korean peninsula, as shown in the location map, were investigated. And the statiscal differences between individuals within population, and between populations were analysed. Twenty trees from each population were selected for this study purpose. Doing this, those trees lagged in growth, usually showing poorer form, were eliminated. The results obtained are summarized as follows: 1. Though the average population ages had the ranage between 50 and 63, the growth of height or diameter was similar. Population No.9 is, however, considered to have better tree forms at glance. Population No.8 showed the heighest value not only in the clear-stem-length ratio. 0.53 but also in the crown-index 0.91. The higher value can be result from those trees having long lateral branches and relatively short crown height, meaning undesirable crown shape. In regard to the fine branchedness and the acuteness of branching angle, the population No.9. is considered to be a better one, whereas there was almost no difference in crown height among populations. 2. Checking the frequency distributions of the ratio of the clear-stem-height to the total height and the crown-indices, some difference between populations are considered. These might be attributed to the previous way of stand mangement which alters the density. 3. In the serration density, the average number of 54 per 1cm needle length, the significant differences exist between individual trees within population but not between populations. A few trees which extremly high serration density were observed. As in serration, so tendencies were in the number of stomata row and resin duct. 4. The population 8 had the resin duct index value of 0.074 as the highest which was twice or triple of the other ones. 5. The patterns of increasing process of the average 10-year-ring-segment were not similar till the 30 years of age, but beyond this, the tendency lines were aggregated. 6. Regading the average summer wood ratio, no diffrence between populations, but in the ranges, i.e. 23 to 30 in population No.8. and 16 to 36 in population No.9., with regad to the specific gravity of wood, there were hardly observed any difference between populations even in the ranges values. As the increase of tree ages, the increase of specific gravity was followed but the increasing patterns were not similar between populations. 7. No significant differences between populations in the average tracheid length and the range were detected. However, the length was increased according to the age increase. The increasing pattern was same between populations.
