정의룡 국제문화기술진흥원 2018 문화기술의 융합 Vol.4 No.4

The aim of this study is to analyze the policy effects of child care leave focusing on the childbirth in South Korea. This instituion of child care leave orinignally seeks to harmonize the work and family. The instituion is increasingly fortified in the receipants and benefits. This study analyze the policy effect of the institution using difference-in-difference method and Korea Welfare Panel Data. The result of the analysis suggest that substantial expansion of child care leave and family-friendly labor environment rebuilding are important.. 본 연구는 육아휴직제도가 출산에 미치는 정책효과에 대한 분석을 수행하였다. 육아휴직제도는 1차적으로 일과가정의 양립을 취지로 하고 있다. 그러나 출산율 제고의 문제가 부각되면서 육아휴직제도 또한 출산장려책의 일환으로 기대되면서 육아휴직의 대상과 급여 혜택 또한 강화되어 왔다. 본 연구에서는 이러한 배경 하에서 복지패널 자료를 활용하여 가임기 여성 및 그 배우자의 육아휴직 혜택 이후 출산효과를 이중차분의 방법을 활용하여 분석하였다. 분석결과 육아휴직제도의 정책효과는 출산에 관한 한 아직까지 긍정적이지 않는 것으로 나타났다. 이러한 분석결과는출산율 제고에 있어서 육아휴직제도의 실질적인 확대 외에 우리나라의 가정친화적인 노동환경 재정립의 필요성을 시사하고 있다.

Identification of Korean Native Pork Using Breed-Specific DNA Marker of KIT Gene

정의룡,정구용 한국축산식품학회 2010 한국축산식품학회지 Vol.30 No.3

Accurate methods for the identification of closely related species or breeds in raw and processed meats must be developed in order to protect both consumers and producers from mislabeling and fraud. This paper describes the development of DNA markers for the discrimination and improvement of Korean native pig (KNP) meat. The KIT gene is related to pig coat color and is often used as a candidate marker. A 538 bp fragment comprising intron 19 of the pig KIT gene was amplified by PCR using specific primers, after which the PCR amplicons of a number of meat samples from KNP and three major improved breeds (Landrace, Duroc and Yorkshire) were sequenced in order to find a nucleotide region suitable for PCR-RFLP analysis. Sequence data showed the presence of two nucleotide substitutions, g.276G>A and g.295A>C, between KNP and the improved pig breeds. Digestion of KIT amplicons with AccII enzyme generated characteristic PCR-RFLP profiles that allowed discrimination between meats from KNP and improved pig. KNP showed three visible DNA bands of 264/249,199, and 75 bp, whereas DNA bands of 249, 199, and 90 bp were detected in the three improved pig breeds. Therefore, the 75 bp DNA fragment was specific only to KNP, whereas the 90 bp DNA fragment was specific to the improved breeds. The breed-specific DNA markers reported here that target the KIT gene could be useful for the identification of KNP meat from improved pig meats, thus contributing to the prevention of falsified breed labeling.

The aim of this study is to analyze the President Directions Item using Semantic Network Analysis. This study has three contributions. First, this study shows the difference of policy directions through the frequency and contents of key words. Second, this study suggest patterns changes of decision-making of the president and bureaucracy through the key words network structure. Third, this study infers the interaction between the president's will and context of institutions. 본 연구는 그간 학문적, 이슈적 관심에서 간과되었던 “대통령 지시사항”에 대한 분석을 수행하였다. 이러한 분석을 통해 대통령의 행정부처 내에서 진행되었던 정책방향의 차이에 대한 이해를 제고시키고, 시대의 흐름을 이해하는데 기여할 뿐만 아니라 향후 정책발굴에 있어서도 도움이 될 수 있음을 확인할 수 있었다. 본 연구는 대통령 지시사항과 관련한 키워드 네트워크 구조에 대한 패턴변화를 의미연결망 분석을 통해 고찰함으로써 대통령의 정책방향차이가 대통령의 의지와 제도적 맥락 간의 상호작용에 연동되고 있다는 시사점을 제공하는데 기여하고 있다.

Association of β-Lactoglobulin Variants with Milk Yield and Composition in Dairy Cattle

정의룡,정구용 한국축산식품학회 2006 한국축산식품학회지 Vol.26 No.1

Major milk proteins have considerable variants which comes from substitution and deletions in their amino acid sequences. Variants in genes that code for milk proteins, such as β-lactoglobulin (β-LG) have been established as genetic markers for milk production and milk protein composition in dairy cattle. The effect of β-LG variant on milk production traits, such as milk yield, fat yield, protein yield, fat percentage and protein percentage, was estimated for 482 Holstein cows in the first lactation. The β-LG variants were determined by PCR-RFLP technique at the DNA level. Single trait linear model was used for the statistical analysis of the data. Results of this study indicated that β-LG variants affected significantly protein yield (p<0.05) and fat percentage (p<0.05). Animals with the AA variant produced 31kg of milk protein more than animals with the BB variant. On the contrary, cows with the BB variant had fat percentage higher by 0.35 and 0.32% compared with cows with the AA and AB variants, respectively. No associations between the β-LG variants and milk yield, protein percentage and fat yield were found. Therefore, milk production traits could be improved through β-LG typing by increasing the frequency of A variant for protein yield or the frequency of B variant for fat content in Holstein dairy cattle population.

Association Analysis between SNP Marker in Neuopeptide Y (NPY) Gene and Carcass and Meat Quality Traits in Korean Cattle

정의룡,신성철,허재필 한국축산식품학회 2011 한국축산식품학회지 Vol.31 No.4

Biological or physiological genes that regulate metabolism and energy partitioning have the potential to influence economically important traits such as carcass and meat quality traits in beef cattle. The neuropeptide Y (NPY) functions as a central appetite stimulator and plays a major role in feed intake and energy-balance control. Therefore, the NPY gene is an excellent biological and physiological candidate gene for body weight, feeding, fatness or growth related traits in beef cattle. The objective of this study was to identify single nucleotide polymorphisms (SNPs) in the NPY gene and to evaluate the association of NPY SNP markers with carcass and meat quality traits in Korean cattle. The genomic region (711 bp) including intron 2 of NPY gene was amplified and sequenced, and five SNPs, g.4389 Del(C), g.4371Del(C), g.4271T>C,g.1899A>G and g.1517A>C, were identified. The PCR-RFLP method was then developed to genotype the individuals examined. The g.4271T>C SNP was significantly associated with M. Longissimus dori area (LDA) value (p<0.027). Animals with the TT (78.144± 0.950 cm2) genotype had higher LDA than those with the CC (72.266±2.039 cm2), and animals with TC genotype showed intermediate value. This SNP genotype also showed a highly significant additive genetic effect for the LDA (p<0.01). No significant associations, however, was detected between any of the SNP genotype and other carcass traits measured in this study. In conclusion, SNP genotype of the NPY gene may be used as DNA markers to select animals that have a higher meat yield.

산업구조와 복지국가 발달 관계에 관한 연구 : Fuzzy-set 질적 비교분석을 활용하여

정의룡 국제문화기술진흥원 2019 문화기술의 융합 Vol.5 No.1

The industrialization theory that industry and economic development of country has an important influence on the development of the welfare state had become a major theory explaining the development of the welfare state. However, the theory of industrialization faced criticism that the size of public welfare was relatively weak even in advanced industrial countries where industrialization developed. To complement and explain these limitations, The theory of democracy that the welfare state could be expanded as a strategy for election competition, and the theory of power-resources theory that welfare states could develop when the power of unions and left parties demanding welfare states were strengthened. This study uses Fuzzy-set analysis for the data of OECD countries adding industrial structure variables to existing theory of the development of welfare state. The result suggests that the proportion of manufacture such as industry structure of country is important for the development of welfare state. 일찍이 복지국가 발달에 산업화가 중요한 영향을 끼친다는 산업화 이론은 복지국가 발달을 설명하는 주요한이론으로 자리매김해 왔다. 그러나 산업화 이론은 산업화가 발달한 서구 선진국가들이라 하더라도 공공복지의 규모는상대적으로 약하다는 비판에 직면하였고, 이러한 한계를 보완, 설명하기 위해 이익집단들이 선거 경쟁에서 승리하기위한 전략으로 공공부문의 복지가 확대될 수 있었다는 민주주의 이론, 복지국가를 요구하는 노조와 좌파정당들의 힘이 강화될 때, 복지국가 또한 발달할 수 있었다는 권력자원 이론 등이 부각되었다. 본 연구는 복지국가 발달을 설명하기 위한 새로운 시도로서 복지국가의 발달에 영향을 주는 기존 이론들에 따른요인들 외에 산업구조에 따른 요인들을 추가하여 퍼지셋 질적비교 분석을 수행하였다. 분석결과 복지국가발달에 있어기존이론 외에 제조업의 비중 또한 복지국가 발전의 중요 요소로서 작용할 수 있다는 점을 발견할 수 있었다. 이러한 분석결과는 산업화 이론, 민주주의와 선거경쟁이론, 권력자원 등과 같은 복지국가를 설명하는 기존이론 뿐만 아니라 제조업 비중과 같은 산업구조 또한 복지국가 발달에 영향을 줄 수 있는 요소임을 시사하고 있다.
