ABSTRACT - This study was performed to evaluate hepatoprotective effect of daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by CCI_4 and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase(LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid perotidation, catalase and glutathione-S-transfrease(GST) in liver microsome were determined in hepatotoxic rats induced by CCI_4. DWT was significantly reduced the serum ALT, AST, ALP, LDH. TC and TG lecels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of CCI_4-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5.000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks.DWT did not induce any toxic signs in the mortalitie, clinical signs, body weight changes, and gross necropsy finfings of mice. Based in these results. It is concluded that DWT may have the hepatoprotective effect on CCI_4 induced hepatotoxicity in rats. Also. DWT may have no side effect and its LD_50 value may be over 5.000mg/kg b.w. in mice.

Whangryunhaedok-Tang (WT) is formulated with Coptidis Rhizoma, Phellodendri Cortex, Scutellariae Radix and Gardeniae Fructus, and Daewhang-whangryunhaedok-Tang (DWT) is made by the combination of Rhei Rhizoma, a wellknown anticostipation drug in WT. Therefore, DWT has been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by corn oil and high cholesterol-diet. Oral administration of DWT significantly inhibited the increase of serum triglyceride and LDL-cholesterol levels, and the decrease of serum HDL-cholesterol levels in hyperlipidemic rats induced by corn oil. Also, oral administration of DWT significantly prevented the increase of serum total cholesterol, triglyceride and LDL-cholesterol, and liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that DWT is effective for the treatment of hyperlipidemia.

The variations of engine performances and exhaust CO-emissions of a four stroke cycle M-combustion type Diesel engine have been measured changing the heat dissipation by coolant flow in the water jacket. The results of study are as follows: (1) The increase in temperature of cooling water brings the decrease in engine heat dissipation at a constant output. (2) The general trends show that the heat dissipation of the test engine increases when maximum pressure in cyliner increases at the constant cooling water temperature. (3) Under the constant engine revolution, the brake fuel-consumption decreases in accordance with emission of carbon monoxide increases in conformity with the decrease of cooling water temperature. (4) The exhaust emission of carbon monoxide increases in conformity with the decrease of cooling water temperature.

This study is based on the hypothesis that the farm income might be improved significantly if the farmers could utilize their own reserved farm resources efficiently. We can often see that farm income is quite different even though farmers have similar resources. Therefore the question arises: "Why should farmers income vary so greatly when similar conditions exist?" The main purpose of this study is to answer this question with regard to management only. To study the problem a survey was conducted. Based on the 1973 mangement year, 80 farms were selected among 40 villages in 16 cities and income through individual business, the farms which achieved the highest levels of income were classified as leading farms, and those farms that had low levels of income were defined as general farms. This study was accomplished by first, identifying the resources available to the two groups of farms classified, second, by comparing the levels of farm income per farm between leading and general farms. Third, tentative management guideline was drawn by analysing the business factors affecting farm income between leading and general farms. 1. First, the total value of the physical assets on the leading farms was 20 percent greater than that of general farms. Second, the total acreage on the leading farms was 21 percent greater than that of the general farms. Third, total productive man-work units of the leading farms was 34 percent greater than that of the general farms. 2. When the human resources on the farms were compared, it was found that the available man equivalent of the leading and general farms were 3.7 and 3.5 respectively, and the used man equivalent were 1.97 and 1.79 respectively. 3. The farm income of the leading farms was 1,275,000 won while the general farms only made 704,000 won. Therefore the level of farm income on the leading farms was 81 percent higher. 4. The differences in farm income was far greater than the differences in resources. The reason for this is farm organization. Generally, as the land area was not the only factor which affected the levels of income. 5. The land cultivated with cash crops in the leading and general farms was 6.5 VS. 2.9 tanbo, the productive man-work units of cash crops were 206 VS. 79, and the gross cash crops receipts were 592,000 won VS. 185,000 won (leading farms first). 6. It was found that cash crops were the critical factor affecting farm income. Thus the leading farms have increased their farm income by a better use of land and by cultivation of more profitable cash crops. It was also found that the leading farms organized their farms mote effectively. 7. On the other hand, given equivalent productive man-work units of cash, farm income was increased when the amount of land cultivated was increased, but given equivalent land, farm income was highly increased relative to the increased productive man-work units of cash crops. In conclusion, the leading farms income was much higher than that of the general farms, regardless of the similarity of available resources, because their farming organization, cropping system, resource use, and attitude towards farm operation were more effective.

The main purpose of this study is to draw a business guideline which can be used by Chonnam Provincial Foundation Seed Farm to improved its own business. In addition, the author expects this study will be a pioneer work to other provincial foundation seed farms in Korea for analysing their business. Also, the author hopes that the result of study should be a useful standard for the government to measure and evaluate the financial budgets submitted and the management accomplished by the farms. To accomplish these purpose, available business data, based on 1975 management year, were collected from the farm. In order to find the starting point to the problem, the national average from the Ministry of Agriculture and Fisheries and the standard farmbusiness data of Chollanamdo area from the National Agricultural Economics Research Institute were used as a comparative measurement for analysing the input-output relationship of the farm. In spite of the efforts consumed, however, the results still have many problems to be reexamined. As yet, having confidence that the findings from the study will be helpful to the foundation seed farms and to the government as well, the author is going to summarize the study as follows: 1. Analysing the management of rice foundation seed and registered seed production per 10a of paddy land, total gross receipts were 103,314 won and total farm expenses were 65,917 won. Consequently, farm income per 10a of land was 37,326 won which is relatively small compared to the national average of 62,016 won. 2. In the case of barley foundation seed and registered seed production per 10a of upland, total gross receipts were 32,149 won, whereas total farm expenses were 39,072 won. As a result, there was a deficit of 6,923 won, which is far below the national average of 16,845 won. 3. Studying the result of soybean foundation seed production per 10a of land, total gross farm receipts were 29,876 won and total farm expenses were 31,856 won. By the result, farm income computed to 1,980 won which will be compared to the standard farm income of 16,451 won of this area, estimated by the National Institute of Agricultural Economics. 4. Seeing the financial statement of potato foundation seed farm bnsiness per 10a of land, total gross recipts were 64,208 won. At the same time, there was 62,661 won worth of farm expense. As a consequence, the net reward from the business was 1,547 won. It, however, is also a very small result compared to the standard farm income of the same area. 5. As pointed out above, the financial perfomance of all kinds of foundation seed prodution farming seems to very small compared to those of general farms. Yet there are acceptable reasons we must recognize. First, the purposes of seed production farms and general farms are quite different. The end purpose of a foundation seed farm is not to earn income but to produce good seed for the general farms. Second, the characteristics of foundation seed farms and general farms are very different. General farms have many self-supply items foundation seed farms, however, mostly supply their inputs from market places. Especially, the one performs its business mostly by its own unpaid family labor, the other, on the other hand, performs its enterprises entirely by employed labor. Besides, the labor requirement of the foundation seed farm is absolutely larger than that of a general farm. 6. In order to minimize the cost of farming, the substitution of labor forces to machinery is recommended. Readjustment of arable land is needed; emoloying a professional technician for machinery replacement is also necessary. 7. To increase the efficiency of labor, a flexible wage unit system rather than the prevailing fixed and unified wage system should be adopted. 8. Finally, encouraging the managers by giving appropriate incentives is also considered as a very important factor to improve over all business efficiency.

This study was aimed to compare the Kiwifruit productivity among 3 different cultivation methods and to find out the most profitable marketing ways. Total 40 farmhouses including Chonnam, Kyongnam, Cheju Province were selected and visited to do several prepared questions. 1. The cultivation types of Kiwifruit were composed of 35.1% open-field cultivation(OPC), 45.1% wind-breaking net cultivation(WBNC), 19.8% vinyl-film house cultivation(VFHC) farmhouses. 46.7% farmhouses had vinyl-film house growing garden in Cheju province, all the growers in Kyongnam province had 100% wind-breaking net growing facility, and 57.6% growers had open-field growing orchard in Chonnam province. 2. Among 3 different cultivation types, The productivity of VFHC was shown the higher as 2,134kg/10a than those of OPC(952kg/10a) and WBNC(359kg/10A). Also, the profitability of VFHC(86.6%) was better than those of OPC(13.8%) and WBNC(14.2%). 3. The growing area of Kiwifruit(per 1 farmhouse) was like this; less 600pyong(p) 5.0%, between 600p. and 2,000p. 42.5%, more 2,000p. 7.5% among all questioned farmhouses. So the 52.5% Kiwifruit farmhouses had less 2,000p. growing area and this means that the cultivation scale is small. 4. The percentage incomes per pyong at 3 different cultivation scales were like followings: less 600pyong(p) 72.1%, between 600p. and 2,000p. 74.4%, more 2,000p. 77.8%, So the larger growing scale makes more returns. 5. On marketing patterns for all harvested fruits(630,300kg), 69.0% fruits were sold through group marketing, 20.5% individual marketing, and 10.5% other ways. 6. The cost of group marketing was 611won per kilogram and this cost is 10.6% higher than individual marketing, however, in terms of practical price for each farmhouses. the price through group marketing(1,928won/kg) was 24.1%, 33% better than individual marketing and other ways each. In conclusion, we propose that the Kiwifruit cultivation types should be changed from OPC, WBNC to VFHC pattern and that the marketing patterns also be changed to group marketing pattern from individual and other marketing ways.

본 실험은 한국, 중국 및 일본 재래종 콩 유전자 자원의 주요형질 변이를 조사하고 이들 자원간의 지리적 유연관계를 비교하고자 수행하였으며, 그 결과를 요약하면 다음과 같다. 1. 경장은 한국(66㎝)이나 일본자원(54.9㎝)보다 중국자원(71㎝)에서 더 컸으며, 또한 변이도 중국자원에서 가장 큰 것으로 나타났다. 2. 개화일수 및 생육일수는 한국자원(65.5일, 151.4일)이 가장 길었으며 중국(57일, 120일)과 일본자원(59.9일, 122.4일)은 같은 경향을 나타냈다. 또한 한국과 중국자원은 지역에 따른 차이를 나타냈으나 일본자원에서는 확인할 수 없었다. 3. 백립중은 한국(18.8g), 일본(17.2g) 및 중국(14.7g) 순으로 무거웠다. 특히 한국자원은 9~11g과 23~25g에서 정점을 나타냈고, 변이폭도 가장 컸다. 반면 일본과 중국자원은 13~17g사이에서 정점을 나타냈다. 4. 협수는 중국(46.9개)이나 일본자원(36.5개)보다 한국자원(75.5개)에서 가장 많았으며, 변이폭도 한국자원에서 가장 컸다. 내도복성은 일본자원에서 가장 강하였다. 5. 정준판별분석결과 can 1을 경계로 하여 오른쪽 상하에 한국재래종이 주로 분포하였고 왼쪽에는 중국과 일본 재래종이 주로 분포하여 각 나라별로 고유한 영역을 가지고 분리되었다. 전체적 경향이 중국과 일본자원이 한국자원보다 가까운 경향을 나타냈다. This experiment was carried out to compare the characters of 944 Korean soybean landraces, 716 Chinese, and 170 Japanese soybean landraces introduced from USDA soybean germplasm collection. Cannonical discriminant and cluster analyses were conducted by their origins. The population from China was taller in plant height than those from Korea and Japan, also its variation was largest in Chinese population. The population from Korea was langer than those from China and Japan in terms of days to flowering and maturity. Also, Korean and Chinese accessions appeared the difference of those traits according to latitude. One hundred seeds weight was in the order of Korean(18.8g), Japanese(17.2g) and Chinese populations(14.7g), especially Korean population was distinguished into two groups; the group including accessions between 10 and 15g, and the other group including accessions between 20 and 25g. However, others showed the peak in range of 13~17g. The number of pod per plant was more in Korean accession(75.5) with the largest variation than Chinese(46.9) and Japanese accession(36.5). The distribution of Korean, Chinese and Japanese accessions reflected the origin of accessions analyzed by cannonical discriminant analysis. The relationship between their geographical origins showed the population of China and Japan are losely related.
