이상영,천동원,한원식 한국농업정책학회, 한국축산경영학회 2001 농업경영정책연구 Vol.28 No.3

According to the analysis results on Korean cattle cooperatives, it is considered that the conditions of members' welfare, payment and education were poor because of short establishment period and unexpected financial crisis. However, the representative's farm management ability and planning was well prepared. Viewing the components of investment in the cooperative, while the proportion of investment in kind was getting bigger, investment in cash and in kind were increased by 28.6% and 78.2%, respectively compared with the beginning stage. Most of the investment in kind was destined to land and facilities. Per capita investment was increased by 11.6million won from 21.3million won at the beginning to 32.9million won. The component ratios of fixed capital such as facility and equipment were composed of 36.4% of subsidy, 43.1% of loan and 20.5% of self-support. Results of the economic analysis on the cooperatives by farming system identified that the highest profitability and productivity were achieved by Type II on increasing value-added followed by Type I of concentrating on hanwoo production, Type III on selling input and Type IV on saving input. Investment analysis based on the amount of allowable investment limit also shows that all farming systems except Type II invested over an appropriate level. Most influential factors affecting cooperative's profitability were record keeping and selling type. The effects of the cooperatives' operating system and subsidy on profitability were statistically insignificant.

소수력발전은 하수처리장 에너지 자립을 위한 효과적인 대안이다. 본 연구는 유량변동이 크고 유효낙차가 낮은 중소형하수처리장(기흥레스피아) 적용을 위해 피치조절형 세미카플란(semi-kaplan) 마이크로수력발전의 적용 타당성을 평가하였다. 가변피치 semi-kaplan 수차는 유량조절을 위한 가이드베인은 생략하고 피치조절형 런너를 장착하여 기계적 결함은 줄이면서 유량변동이 큰 처리장에 특화된 기술이다. 마이크로수력발전 시스템은 설계조건(유량 0.35 m3/s, 유효낙차 4.7 m)에서 90.2%의 수차효율 달성이 가능하였고 발전용량은 13.4 kW로 산정되었다. 설비가동률 74%로 가동 시 연간 약 86.8 MWh 에너지 생산을 통해 2.1%의 에너지 자립이 가능하고 이는 연간 49톤의 CO₂ 감축효과와 맞먹는다. 경제성 평가결과 초기 건설공사비가 200,000,000원 이하인 경우에는 내부수익률은 6.1%, 순현가는 15,539,000원, 편익-비용률은 1.08, 투자회수년은 15.5년으로 경제성이 충분한 것으로 나타났다. Small scale hydropower is one of most attractive and cost-effective energy technologies for installation within sewage treatment plants. This study was conducted to evaluate the potential of a semi-kaplan micro-hydropower (MHP) system for application to sewage treatment plants with high flow fluctuations and a low head. The semi-kaplan MHP is equipped with an adjustable runner blade, and is without a guide vane, so as to reduce the incidence of mechanical problems. A MHP rating 13.4 kWp with a semi-kaplan turbine has been considered for Kiheung Respia sewage treatment plant, and this installation is estimated to generate 86.8 MWh of electricity annually, which is enough to supply electricity to over 25 households, and equivalent to an annual reduction of 49 ton CO₂. The semi-kaplan turbine showed a 90.2% energy conversion efficiency at the design flow rate of 0.35 m3/s and net head of 4.7 m, and was adaptable to a wide range of flow fluctuations. Through the MHP operation, approximately 2.1% of total electricity demand of Kiheung Respia sewage treatment plant will be achievable. Based on financial analysis, an exploiting MHP is considered economically acceptable with an internal rate of return of 6.1%, net present value of 15,539,000 Korean Won, benefit- cost ratio of 1.08, and payback year of 15.5, respectively, if initial investment cost is 200,000,000 Korean Won.

김천제,최수일,한의수,이효진,고원식 건국대학교 동물자원연구센터 1991 動物資源硏究誌 Vol.16 No.-

본 연구는 국내에서 생산되고 있는 돈육 luncheon meat과 수입 luncheon meat의 성분조성 및 품질을 비교 평가하기 위하여 실시하였다. 그 결과를 요약하면 다음과 같다. 1) 국산돈육 luncheon meat의 수분함량은 57.2%로 수입품(53.1%)보다 높았으며 조지방 함량은 수입품(53.1%)보다 높았으며 조지방 함량은 수입품이 26.6%로 국산품(20.6%)보다 높았다. 그러나 조단백질 함량은 거의 같았다. 2) 국산돈육 luncheon meat와 수입품 모두 대장균이 검출되지 않으며, 타르색소(tar colors)도 사용하지 않은 것으로 나타났다. 3) 국산돈육 luncheon meat의 NO₂의 함량은 4 ∼ 35ppm으로 돈육수입 luncheon meat(1.7∼6ppm)보다 높았다. 4) 국산돈육 luncheon meat의 TBA가는 0.09∼0.13로 비교적 낮았으나, 유통기간이 긴 수입돈육 luncheon meat는 0.09∼0.39로 국내제품에 비하여 상대적으로 높은 값을 나타내었다. 5) 국산돈육 luncheon meat의 VBN(12.3∼18.4mg%)은 수입품(15.7∼18.2mg%)보다 낮았다. 6) 수입 luncheon meat는 국산 luncheon meat보다 jelly loss가 약2배 높았다. 7) 경도는 국산돈육 luncheon meat통조림이 수입품보다 높은 것으로 나타났으나, 탄력성과 응집성은 큰 차이가 나지 않았다. The aim of this study was to assay and compare the ingredient or composition and quality of imported pork luncheon meat with those of domestic's. The results obtained were as follows. 1. The amount of water in domestic pork luncheon meat products(57.2%0 was higher than that of imported products(52.2%0, and the content of crude fat in imported products(26.6%) was higher than that of domestic products(20.6%). The amount of crude protein, however, both domestic and imported products was approximately the same. 2. E.coli was not found in both domestic and imported products. No tar-colors were detected in both samples. 3. The amount of NO₂in domestic pork luncheon meat products(4 to 35ppm) was higher than that of imported products(1.7 to 6ppm). 4. The TBA-value of domestic pork luncheon meat products(0.09 to 0.13) was relatively low, whereas the value of imported products was higher than that of domestic products(0.09 to 0.39). 5. The VBN-value of domestic luncheon meat products(12.3∼18.4mg%) was lower than that of imported products(15.7∼18.2mg%). 6. The jelly loss of imported pork luncheon meat products was approximately 2 times higher than that domestic's . 7. The hardness of imported pork luncheon meat products was lower than that of domestic products. Elasticity and coheshiveness in both products were not significantly different.

본 연구는 교육과학기술부의 경쟁력있는 국립대학을 만들고자 시행하고 있는 여러 정책 중 연합대학으로의 체제 변화 권유에 대한 장단점과 이해득실을 냉철하게 객관적으로 고찰해 보고자 수행되었다. 연구의 수행방법은 연합대학 체제의 추진이나 독자생존의 길 등 의사결정에 참고자료가 될 수 있도록 일본과 미국 등 외국의 연합대학 사례를 중심으로 수집 가능한 자료를 수집하여 고찰한 후 연합대학 체제 추진이나 독자생존의 장단점을 알아보았다. 본 연구의 결과는 여러 가지 외적인 상황 속에서 우리 대학이 독자적으로 생존하는 것이 가능한가, 또는 결국에는 독자적 생존의 대안으로 연합 내지는 통합의 길을 선택할 수밖에 없는가 하는 것은 그 누구도 쉽게 예단하기 어렵다는 것이다. 그러나 대학 구성원들이 미래를 선택하지 않는다 하더라도 외적인 요인에 의해 미래가 결정될 여지가 있으므로 지금부터라도 대학의 미래에 관한 공동의 지혜를 모아야 할 것으로 생각한다. 함께 머리를 맞대고 허심탄회하게 서로의 의견을 존중하며 서로에 대한 불신을 털어버리고 진정 대학의 미래를 위한 바른 선택이 무엇인가에 관한 논의와 연구가 꾸준하게 지속되어야 할 것으로 판단된다. This study was carried out in order to try to consider objectively merits and demerits regarding a system change invitation toward the Union University System and understanding gains and losses during a lot of policies to make a national college that there was competitiveness of Ministry of Education, Science and Technology of education. The results of this study is that no one is easy to predict, that it does as alternatives of an independent survival or select a street of integration and the Union University System in various external situations, finally. However, the University members does not select the future even if in various external factor because there is no doubt that the future will be decided from now on any University in the future regarding collaborative wisdom of the university, We thought it was going to do. Head with open-minded to respect each other's opinions and distrust each other confide you discard the truly University for the future, select the right to discuss and research can be sustained.

산전광산의 천열수 금-은 광화작용

Within the Hyeongseong area, Kangwondo Province, occur many gold-silver-bearing hydrothermal vein deposits. Geologic setting, ore occurrence, mineral paragenesis, and genetic environments of Au-Ag quartz vein deposits in the Sanjeon mine, a representative mine in the area, are elucidated in this study. Gold-silver mineralization of the Sanjeon mine occurs in epithermal quartz veins which filled fault fractures in quartz porphyry. Ore mineralogy is simple, being composrd of base-matal sulfides (mainly sphalerite, pyrite, galena, and arsenopyrite) and Au-Ag minerals [electrum (24∼40 atomic % Au), argentite, native silver, and pyrargyrite)]. Fluid inclusions show that mineralization was mainly formed at a relatively low and narrow temperature range (150°∼ 250℃). Fluid pressures were about 70bars, corresponding to a hydroststic head of about 600m. Gold deposition occurred mainly at temperature of 210°∼ 250℃ as a combined result of the decreases of temperature and activity of H2S and the increase of pH, due to the boiling of ore fluids. Later deposition of silver minerals such as native silver was mainly a result of cooling and dilution of ore fluids at a temperature range of 150° to 190℃, due the inundation of circulating meteoric water.

용접공에서 혈중 중금속 농도와 혈장중 Malondialdehyde, α-tocopherol 및 적혈구내 Superoxide Dismutase 활성도에 관한 연구

이원진,장성훈,황천현,천병철,김해준 大韓産業醫學會 1998 대한직업환경의학회지 Vol.10 No.2

We investigated the association between the oxidative stress and the concentration of heavy metals in blood among welders. The study subjects were male manual CO₂welders(N=127) exposed to several heavy metals. The age distribution was from 20 to 63(GM=33.7) and the geometric mean(GM) of work duration was 4.2 years. We analyze the level of blood lead, cadmium, manganese and chromium which was related with the oxidative stress in the animal studies. Blood selenuim, plasma malondialdehyde(MDA), plasma α-tocopherol and erythrocyte superoxide dismutase(SOD) were analyzed as biological markers of the oxidative stress. The results of univariate analysis showed that the plasma MDA was significantly correlated with α-tocopherol(r=0.327) and blood selenium(r=0.313) concentration. But we could not find out any relationship between the erythrocyte SOD activities and those metal concentrations. Neither smoking nor alcohol consumption was related to the level of heavy metals and the oxidative stress biomarkers. As the results of multiple regression analysis with stepwise selection method, 1) the change of MDA level were dependent with the level of α-tocopherol and blood selenium concentration(R²=19.7), 2) the plasma α-tocopherol level was dependant with MDA and blood chromium concentration(R²=15.6), 3) in case of erythrocyte SOD activity, only the duration of work was significantly selected.
