The purpose of this study was to survey the recognition and the actual state of use of Native pork. The recognition on Native pork were examined using a questionary to eight hundred males and females in Kyeongbuk and Daegu. The results were as follows : The meats which they often ate in the order of pork, beef and chicken. When people eat out, 43.7% of those ate pork and 42.7% of those ate beef, the younger people liked pork more than the older people. The recognition on pork dishes showed the a high mean value of 3.38 to "I like pork dishes" . 53.5% of the respondants liked three-ply flesh and 33.6% of those liked rib among the part of pork. The favorite pork dish was pork roast meat at 48.1%, Kimchichige at 13.6%, and sweet and sour pork 10.9%. Suitable and garnish food with pork were lettuce, sesame leaf and garlic, and alcoholic drinks such as soju. The Native pork showed a higher mean value than improved pork in taste(lightness, tasty), sticky meat quality, low fat content and good food for health. 30.9% of the respondants recognized as a traditional food. 59.1% of respondants have used the native pork, ingest place came out special eating house 42.2%, 38.3% of respondants suggested 'convenience of purchase' and 31.6% of those suggested 'low price' as facts that has been improved in the native pork.

목적: 당뇨병성 신증의 원인 기전으로 염증반응이 관계한다고 알려진 이후 염증반응을 억제하고자 하는 시도가 있어왔다. 항염증 작용이 있는 retinoid는 면역성 신질환과 당뇨병에서 세포 외 기질 단백의 축적을 줄인다고 보고되었다. 그러나 retinoid가 당뇨병성 신증의 진행에 어떠한 역할을 하는지에 대해서는 연구가 미미한 상태이다. 이에 retinoid가 당뇨병성 신증의 진행과정에 관여하는 염증 작용을 차단할 수 있는지 규명하고자 하였다. 방법: Streptozotocin (STZ)을 쥐에 주사하여 당뇨를 유발시켜 염증 반응을 활성화한 뒤 retinoid를 투여하여 monocyte chemoattractant peptide-1 (MCP-1) 발현을 측정하여 항염증 효과를 평가하였다. 결과: 당뇨가 유발된 쥐들에서 군간 혈당 차이는 없었다. 당뇨 발생 초기 (2일)에 차이가 없던 24시간 요 단백양이 4주 후에는 증가되었고, 당뇨군 내에서는 retinoid를 투여한 군에서 투여하지 않은 군에 비해 단백뇨 양이 감소되는 경향을 보였다. 소변에서 발현된 MCP-1 단백양은 비당뇨군에 비해 당뇨군에서 초기부터 증가하는 경향을 보이다 4주 후에는 의미있게 증가하였다. 당뇨군에서 증가한 소변내 MCP-1 단백 발현이 retinoid를 투여한 경우 약 제를 투여하지 않은 군에 비해 감소하는 경향을 보였다. 신장 피질에서 추출한 RNA에서 MCP-1의 발현을 측정한 결과 비당뇨군에 비해 당뇨군에서 의미있게 증가되었으나 retinoid 투여효과는 관찰되지 않았다. MCP-1에 대한 면역 조직 화학 염색 결과 2일째부터 MCP-1 발현은 당뇨군에서 대조군에 비해 증가되어, 4주 후에는 의미 있게 차이가 났으며, retinoid를 투여한 경우 MCP-1의 발현은 뚜렷이 감소되었다. 결론: STZ 유발 당뇨쥐에서 MCP-1 단백 발현이 증가되는 것을 인하였고, 증가된 MCP-1 발현이 retinoid를 투여하는 경우 감소하는 것을 확인하였다. 이를 통해 당뇨병성 신증의 진행과정 중 retinoid가 염증반응을 차단할 수 있을 것으로 예상하였다. Background : An inflammatory mechanism has been suggested to contribute to the progression of diabetic nephropathy. Although retinoid, a known anti-inflammatory agent. has been reported to be beneficial in some experimental renal diseases, it has not been shown whether it prevents disease progression in diabetic nephrogathy. Therefore, we investigated whether all-trans retinoic acid inhibits inflammatory changes and improves renal function during the early stages of diabetic nephropathy in streptozotocin-induced diabetic rats. Methods : We evaluated anti-inflammatory effect of retinoid on streptozotocin-induced diabetic nephropathy. Anti-inflammatory effect was determined by the expression of monocyte chemoattractant peptide-1 (MCP-1). Results : Urinary protein excretion was significantly higher in diabetic rats at four weeks after the induction of diabetes mellitus compared with controls, and proteinuria in the group with retinoic acid treatment was decreased (1.25±0.69 vs. 0.78k0.72 mg/mg Cr, p=0.056). Urinary excretion of MCP-1 was rapidly increased at two days after induction of diabetes mellitus in diabetic rats, and further increased until four weeks of age compared with control rats. Retinoic acid treatment suppressed to 30% reduction of the urinary level of MCP-1 compared with vehicle treated diabetic rats (l19.3 ± 74.2 vs. 78.1±62.7 pg/mg Cr, p=0.078). Immunohistochemistry revealed a significant increase in staining for MCP -1 protein in the diabetic kidney, and retinoic acid treatment significantly suppressed intrarenal MCP-1 protein synthesis. Conclusion : Retinoic acid suppressed proteinuria and inflammatory changes in diabetic rats. These results suggest that retinoic acid may have an anti inflammatory effect in diabetic nephropathy.

해양연구를 위해 사용하는 연구선은 계획된 연구해역으로 이동하여 연구목적에 맞는 해양관측을 수행한다. 한국해양과학기술원(KIOST, Korea Institute of Ocean Science & Technology)이 보유하고 있는 5척의 연구선에는 항해 중에 상시 관측할 수 있는 GPS, 수심, 기상, 표층 수온 및 염분 측정 장비가 탑재되어 있다. 이러한 상시관측 장비를 통해 생산되는 데이터를 체계적으로 관리하고 활용하기 위한 정보 플랫폼이 요구된다. 따라서 연구선 운항계획에서부터 연구선 운항 중관측, 데이터수집, 데이터처리, 데이터저장, 표출 및 제공서비스에 이르는 일련의 업무 분석을 통해 업무절차를 정의하였다. 업무 절차의 각 단계 별 기능 설계를 거친 후, WebGIS 기반의 정보플랫폼인 KUMOS(KIOST Underway Meteorological & Oceanographic Information System)를 구축하였다. 연구선 항해 중에 생산되는 데이터는 시·공간적 변화가 있는 특성이 있어 이러한 변동성을 고려한 데이터의 품질관리 체계를 개발하였다. 데이터의 체계적인 관리와 서비스를 위해 KUMOS 통합DB를 구축하고 연구선 항적, 데이터 표출, 검색 및 제공 등의 기능을 구현하였다. KUMOS에서 제공하는 데이터 셋은 연구선의 항해 별 운항결과리포트(cruise report), 원시데이터(raw data), 품질관리 플래그(Quality Control(QC) flagged data) 데이터, 필터 데이터(filtered data), 항적도 데이터(cruise track line), 데이터 리포트(cruise data report) 등으로 구성되어있다. 본 연구를 통해 개발한 KUMOS의 기능 별 업무처리 절차와 체계는 연구선 항해 중 상시관측이 가능한 연구선을 보유하고 있는 국내 해양관련 기관 및 대학에도 벤치마킹 역할을 할 것으로 기대된다. Research vessels(R/Vs) used for ocean research move to the planned research area and perform ocean observations suitable for the research purpose. The five research vessels of the Korea Institute of Ocean Science & Technology(KIOST) are equipped with global positioning system(GPS), water depth, weather, sea surface layer temperature and salinity measurement equipment that can be observed at all times during cruise. An information platform is required to systematically manage and utilize the data produced through such continuous observation equipment. Therefore, the data flow was defined through a series of business analysis ranging from the research vessel operation plan to observation during the operation of the research vessel, data collection, data processing, data storage, display and service. After creating a functional design for each stage of the business process, KIOST Underway Meteorological & Oceanographic Information System(KUMOS), a Web-Geographic information system (Web-GIS) based information platform, was built. Since the data produced during the cruise of the R/Vs have characteristics of temporal and spatial variability, a quality management system was developed that considered these variabilities. For the systematic management and service of data, the KUMOS integrated Database(DB) was established, and functions such as R/V tracking, data display, search and provision were implemented. The dataset provided by KUMOS consists of cruise report, raw data, Quality Control(QC) flagged data, filtered data, cruise track line data, and data report for each cruise of the R/V. The business processing procedure and system of KUMOS for each function developed through this study are expected to serve as a benchmark for domestic ocean-related institutions and universities that have research vessels capable of continuous observations during cruise.

The purpose of this study is to identify the effects of ecological experience on the university students`` environmental consciousness. Experimental group was appeared high in the post-test in environmental consciousness(p<.05). Comparative group was appeared high in the post-test in environmental consciousness but there was not any statistically significant difference in the change. The result shows that ecological experience is very helpful for university students to realize the importance of environmental pollution and conservation of nature. Consequently, the environment education in a school or a society is expected to introduce ecologically useful programs applying elements of natural environment and activating natural experience activities through those programs.

Beet armyworm, Spodoptera exigua are difficult to control using chemical insecticides because of the development of insecticide resistance. For eco-friendly beet armyworm managements, various control agents are required. Entomopathogenic fungus is one of promise control agents as an alternative to chemical control agent. We isolated entomopathogenic fungi from soil samples of suwon by insect-bait method using Galleria mellonella and conducted bioassay to larva of beet armyworm. As a result of bioassay isolate FG274, FG340, FG344 had high virulence as 100% against second instar larva of S. exigua. To identify the fungus isolates, their’s morphological characteristic was observed and ITS of 18srRNA was sequenced. ITS sequence of FT274, 340, 344 were highly matched (100%) to that of Beauveria bassiana, Paecilomyces fumosoroseus, Metarhizium anisopliae. To investigate the optimal concentration, three isolates were sprayed at three different concentration(1×106 ,107 and 108 conidia/㎖) in laboratory conditions. 나타내었다.
