음식물류폐기물 혼합 가축분 퇴비(이하, 음폐 퇴비) 사용은 농경지의 작물 생산량 증가 및 토양 이화학성 개선 등의 효과가 있는 것으로 알려져 있다. 반면, 농경지의 과도한 음폐 퇴비 사용은 작물 생육 저해, 농경지 양분 유출로 인한 하천의 부영양화 등 토양 환경에 역효과를 일으킬 수 있다. 이에 본 연구는 음폐 퇴비(Food Waste Compost with Manure, FWC)의 사용량을 달리하여 노지에 처리하였을 때 고추의 생육 및 수량에 미치는 영향을 구명하기 위해 수행하였다. 본 연구의 처리구는 무처리구 (NF), 무기질비료 처리구(NPK50%, NPK 100%), 음폐 퇴비와 무기질비료 50%를 투입한 처리구(NPKFWC1, 2, 3)로 달리하였다. 시험 후 토양 화학성 결과, 음폐 퇴비 사용량이 증가함에 따라 유기물, 유효인산, 교환성 양이온 등의 함량이 증가하였다. 고추 생육 조사 결과, 1년차 전체 주당 생체중과 건물중은 NPKFWC1, 2에서 NPK 100%와 통계적 유의성은 없었으며, 음폐 퇴비를 3배 처리한 NPKFWC3은 NPKFWC1, 2에 비하여 약 10% 감소하였다. 2년차 전체 주당 생체중은 NPKFWC1에서 가장 높았으며, 이는 NPK 100%에 비하여 약 29% 높았다. 또한, 음폐 퇴비 사용량이 증가함에 따라 수량은 감소하는 경향이었다. 본 연구 결과, 음폐 퇴비의 사용량이 증가함에 따라 양분의 과량 축적 및 고추 생육이 저해되는 경향을 보였다. 결론적으로, 음폐 퇴비 사용 시 정량(1,309 kg 10a-1)을 사용할 것을 추천하며, 장기적 사용 시 노지 및 시설 등의 작물 영향 평가 등의 관한 추가적인 연구가 필요한 것으로 판단된다.

본 논 문 에서는 직사각형 형태의 사용후 핵연료 저장구조물 에 대한 내진해석을 다루었다. Eulerian 과 Lagrangian 의 두가지 해석방법 을 사용하여， 그 결 과를 비교하였다. Eulerian 접 근 방법에서는 유체 운동에 대한 Laplace 방정식의 경계치 문제를 푼 반면， Lagrangian 접 근 방법에서는 저 장구조물은 고체 유한요소로 모 형화 하였고， 내부유체 는 유체 유한요소로 보형 화 하였다. 유체영역 을 모형화 하는데 사용된 유체요소의 강성올 적 절히 산정하기 위하여 (1 x 1) 의 갑차적 분을 적 용하였다. 응답스펙 트럼 해석 법으로 유체 구조물 상관관계의 내 진 해석 올 수행한 결 과， 뚜 접 근 방볍으로 구한 벽면에 작용하는 유동압이 장 일치 함을 알 수 있었다. 또한 벽면 유연성의 영향을 포함할 경 우， 지 진 발생시 벽면에 작용 하는 유통 압이 크 게 증가할 수 있 음올 알았다.

Background : Cordyceps militaris has been an wonder drug to anti-aging efficacy and called the three main drugs with ginseng and deer antler from the past. Cordycepin, cordycepic acid (d-mannitol) and adenosine are known as functional ingredients in Cordyceps militaris. Among them, cordycepin, the representative component, has been reported as antimicrobial substance containing immune enhancement, anti-cancer and anti-inflammatory effects. Methods and Results : After Cordyceps militaris produced from different types of medium mixed with 10-fold volume of purified water, the mixture were extracted at 70±5℃ for a hour and that extracts re-extracted using ultrasonics wave for 30 minutes. Qualitative analysis of the index component was determined by using the Q-TOF (A quadrupole time-of-flight mass spectrometer), and quantitative analysis was performed by using HPLC (high-performance liquid chromatography) with Xselect HSS T3 column (2.1 X 100 mm, 2.5㎛, Waters, USA) and ultrapure water and acetonitrile as mobile phase A and B. Detection column temperature, injection volume and the flow rate were 35℃, 2 μL and 0.3 mL / minute respectively. The cordycepin content of Cordyceps militaris produced from medium mixed with vegetable and animal ingredients higher than single ingredient. Moreover, through a variety of analyzes by varying the type and content of the medium additives, the cordycepin in Cordyceps militaris produced from medium mixed with animal ingredients highest. Furthermore, the cordycepin content of a fruit body was higher than those of the a mycelium. Conclusion : These results provide a method for producing an high cordycepin content of Cordyceps militaris as functional food ingredient.

Background : Recently, there is a urgent demand for development of new varieties with enhanced resistance to various biotic/abiotic stresses. In order to develop ginseng varieties with such traits, systematic breeding program and comprehensive field studies are prerequisite. Methods and Results : ‘Cheonmyeong' seeds were collected in 2008 from the farmer field of Buyeo. Physiological investigation and propagation were conducted from 2009 to 2011. It was given the name 'Eumseong No. 8 through the observed yield trial from 2012 to 2013 and local adaptability was carried out from 2014 to 2015. All phenotypes including agronomic characteristics, seed yield, and physiological response to biotic/abiotic stresses were investigated according to the ginseng GAP and UPOV guidelines. Yellow-red leaf and pink berry at maturing stage were observed. The time of emergence, flowering and berry maturity of the ‘Cheonmyeong’ were faster than those of ‘Chunpoong’. Stem length of ‘Cheonmyeong’ was shorter than that of ‘Chunpoong’, whereas stem diameter was thicker than that of ‘Chunpoong’. Main root length was shorter but main root diameter is thicker than that of ‘Chunpoong’. Number of seeds of ‘Cheonmyeong’ was fewer than that of ‘Chunpoong’ but 1,000-seeds weight and stratification rate were higher than those of ‘Chunpoong’. The yield performance of this variety was 661 kg/10 a in local adaptability test for two years, which is 22% higher than that of ‘Chunpoong’. ‘Cheonmyeong’ showed strong resistance to phytophthora blight, mulberry mealybug and nematode and moderate resistance to alternaria blight. ‘Cheonmyeong’ did almost not occur yellow spot of aerial part and rusty skin of root, show moderate resistance at high temperatures. Conclusion : Our study demonstrated that ‘Cheonmyeong’ is an ideal variety with heavier root weight and enhanced stress resistance and contribute will enhance biotic/abiotic stress resistance and increase the farmers' income.

Olive flounder Paralichthys olivaceus is one of the most widely cultured fish species in Korea. Although olive flounder receive attention from aquaculture and fisheries and extensive research has been conducted eye morphological change in metamorphosis, but little information was known to molecular mechanism and gene expression of eye development- related genes during the early part of eye formation period. For the reason of eyesight is the most important sense in flounder larvae to search prey, the screening and identification of expressed genes in the eye will provide useful insight into the molecular regulation mechanism of eye development in olive flounder. Through the search of an olive flounder DNA database of expressed sequence tags (EST), we found a partial sequence that was similar to crystallin beta A1 and gamma S. Microscopic observation of retinal formation correspond with the time of expression of the crystallin beta A1 and gamma S gene in the developmental stage, these result suggesting that beta A1 and gamma S play a vital role in the remodeling of the retina during eye development. The expression of crystallin beta A1 and gamma S were obviously strong in eye at all tested developing stage, it is also hypothesized that crystallin acts as a molecular chaperone to prevent protein aggregation during maturation and aging in the eye.
