Tarak is our own traditional fermented milk made through lactic acid fermentation by using makgeolli as inoculum for milk or using already made tarak as inoculum but it is hardly known to people as its related studies are also insufficient. Accordingly, the purpose of this study was to manufacture jelly by using tarak and analyze its quality characteristics for the diversification of consumption promotion and demand of traditional fermented milk tarak. Tarak jelly that was made according to the percentage of adding tarak showed a tendency that the content of crue protein, crude fat and crude ash except for moisture water meaningfully increased as the amount of tarak added increased (P<0.05). In the case of pH, it declines as the amount of tarak added was high. The chromaticity measurement result of tarak jelly was 54.32 in the case of control group for L, and it increased as the amount of tarak added increased. In the case of a, it decreased as tarak was added, whereas b meaningfully increased. There was meaningful difference between samples in the case of chewiness, fracturability and adhesiveness (p<0.05). The sensory test result showed that there was meaningful difference between samples in their appearance and taste but there was no meaningful difference in the case of overall preference, scent and texture.

이경연,유성란,정기철,장병귀,최강덕,이준헌,Lee, K.Y.,Yu, S.L.,Jung, K.C.,Jang, B.K.,Choi, K.D.,Lee, J.H. 한국가금학회 2007 韓國家禽學會誌 Vol.34 No.2

한국 재래닭에서 성장에 따른 유전자들의 발현 변화를 알아보고 성장 촉진, 대사 및 면역 관련 유전자를 발굴하기 위하여 주령별로 닭의 간에서 RNA를 추출하였으며 10개의 arbitrary ACPs를 이용하여 차등 발현되는 유전자를 조사하였다. 발현량에 현저한 차이를 보이는 5개의 유전자들이 선별되었으며, 이 중 3개의 유전자들은 BLAST search 결과 이미 기능이 알려진 FTH1, SAA와 HSP90B1으로 밝혀졌다. 그러나 2개의 유전자들은 닭의 genome sequence가 끝났음에도 불구하고 기능이 밝혀져 있지 않아 앞으로 이 유전자들의 기능에 대한 연구가 지속되어야 함을 의미한다. 본 연구에서 닭의 간에서 성장 단계별로 발현 차이를 보이는 유전자들은 앞으로 다른 유전자와 단백질들과의 관계를 통하여 닭의 성장 및 지방 대사를 이해하는데 도움을 줄 것으로 사료된다. The chicken liver has been involved in various biological functions including detoxification, glycogen storage and plasma protein synthesis. The aim of this study was to investigate differentially expressed genes in chicken liver in four different growing stages. Using 10 arbitrary Annealing Control Primers (ACPs), five differentially expressed genes have been identified. Based on the Basic Local Alignment Search Tool (BLAST) search results, three of them were matched with previously known genes, and the other two were matched with unknown EST sequence and a hypothetical protein, respectively. In order to confirm the expression results, quantitative real-time PCR was also performed. The high similarities between the expression data using arbitrary ACPs and quantitative real-time PCR indicate that the identified genes are the real differentially expressed genes in different growing stages. The genes identified in this study can be used as valuable biomarkers in chicken with further investigation of the functions.

본 연구의 목적은 교육부와 시·도 교육청 ‘학교 예술교육 활성화 추진 계획’을 비교 분석하여 정부 및 시·도 교육청 차원의 학교 예술교육 정책 현황을 살펴보고, 교육부와 시·도 교육청 추진 계획의 개선 방향을 모색하는 것이다. 비교 분석 결과 다음과 같은 개선 방향을 제안하였다. 첫째, 시·도 교육청 추진 계획은 교육부의 추진 계획을 참고하되 지역의 특수성을 반영한 차별화된 내용이 담길 수 있도록 해야 한다. 특히 지역 차원에서 학교 예술교육을 내실화 할 수 있는 방안이 구체적으로 제시되어야 한다. 둘째, 교육부 추진 계획 작성 시 시·도 교육청에서 반드시 추진해야 할 중점사업과 자율적으로 운영할 수 있는 사업을 구분하고 차별화하여 관리할 필요가 있다. 셋째, 차년도 교육부 추진 계획 작성 시 당해연도 시·도 교육청 추진 계획을 참고하여 시·도 교육청의 실정을 반영하여 작성할 필요가 있다. 넷째, 교육부 추진 계획 발표 시기를 앞당기고 이를 참고하여 시․도 교육청 추진 계획을 작성하도록 권고할 필요가 있다. The purposes of this study were to compare and analyze Ministry of Education and municipal and provincial education offices in “Activation Plan for Art Education in School,” examine the current policies for art education in school at the government level and at the level of municipal and provincial education offices, and search for improvement directions for the plans propelled by Ministry of Education and municipal and provincial education offices. Based on the comparison and analysis results, the study proposed the following improvement directions: first, municipal and provincial education offices need to consult the plans of Ministry of education and reflect differentiated content to reflect the unique features of local areas when making their plans. It is especially important that their plans should contain specific plans to strengthen art education in school at the local level. Second, Ministry of Education needs to distinguish and differentiate the main projects that must be implemented by municipal and provincial education offices from the projects that can be implemented by them autonomously for the management purposes when making its plans. Third, Ministry of Education needs to consult the plans being pushed forward by municipal and provincial education offices for the year and reflect the actual state of municipal and provincial education offices when making plans for the next year. Finally, there is a need to recommend that Ministry of Education should advance the date of announcing its plans and that municipal and provincial education offices should consult them to make their own plans.
