This paper summarizes the results of these efforts by offering a photovoltaic system structure in 50㎾. The combination of photovoltaic system components are interconnected and system monitoring system will be summarized for the purpose of the increasing safety in this article. This paper describes configuration of utility interactive photovoltaic system which generated electric power supplies to dormitory. In order to installing the middle or large scale photovoltaic system, It must investigated the optimal design of system, compute quantity of power generation, economic rate of return and so on. In this paper represent 50㎾ utility photovoltaic system examination, developed simulation results and financial analysis. The performance of photovoltaic system has been evaluated, analyzed with simulation and financial analysis results. The results obtained in this research will be much useful to prior investigation for installing utility interactive photovoltaic system.

본 연구는 재래닭의 성장 관련 유용 유전자를 검색하기 위하여, 재래닭에서 발현되는 유전자와 코니쉬에서 발현되는 유전자를 subtraction하여 cDNA library를 구축하고, 염기서열을 밝혀서 재래닭 특이 유용 유전자를 검증하고자 하였다. cDNA library에서 얻은 clone들의 염기서열을 분석하여 나타난 결과를 5개의 clone을 비교 분석하였다. Clone NDS-1(618nt)은 비록 타 종과의 상동성은 낮으나(10%) 해당 과정에서 중요한 역할을 담당하는 triosephosphate isomerase이며, Clone NDS-6(651nt)는 자에서 해당 과정에 관여하는 glyceraldehyde-3-phosphate dehydrogenase로 여겨진다. 그러나 3가지 유전자(clone NDS-2, NDS-10, NDS-12)는 다른 유전자들과 비교하여 5.0%내외의 낮은 상동성을 보이고 고등 동물과 거의 유사성이 없으므로 재래닭 특이 성장 관련 유용 유전자일 가능성이 있다. This experiment was conducted to examine the effective DNA related with muscle growth of Korean native chicken. cDNA library was constructed with mRNA subtraction from Korean native chicken to Cornish. Total mRNA was purified from pectoralis muscle of adult chicken. Five clones were compared their DNA sequence and characteristics based on GenBank. Clone NDS-1 (618nt) was low homology (10%) with other species, but it is closely related with triosephosphate isomerase which is play an important role in glycolysis. Clone NDS-6 (651nt) is corresponding to glyceraldehyde-3-phosphate dehydrogenase. These two clones are encoding to enzymes in key role in glycolysis. However, other three clones (NDS-2, NDS-10, NDS-12) have low homology with other species about 5.0%. These clones were not similar with any other eukaryotics. Therefore, three clones (NDS-2, NDS-10, NDS-12) are high possibility of specific DNA for muscle growth in Korean native chicken.
