This paper is attempted to find the causes of poverty in Korean rural community by surveying the various socio-economic organizations, especially "Gyes"(so-called,mutual finance associations) In Western countries,as Max Weber pointed out, Capitalism was propelled by Protestant ehics. In Korea, however, it seems impossible to find such a spiritual impulse. Especially farmers are never trained to apply themselves to capitalistic competition, and they are adhered to feudalistic and pre-capitalistic ideology. Korean farmers' ideology is chiefly influenced by Confucianism. The ideology of Confucianism is based on rationalism of present world, with the assumption that character and essence of human being is originally honest and good. Korean farmers prefer thespiritual and social values to material wealths. It is the very reason why Korean farmers are so poor in economic aspect. But it is very difficult to find the causes of their poverty from that view of value because of its abstractness. This situation made me to survey the various socio-economic organizations to grasp their concerns and view of value. It seemed possible to find their view of value and the causes of thier poverty by observing and analysing the socio-economic organizations, especially"Gyes." Korean people have been organizing"Gyes"spontaneously without any interferences and orders. They have been enjoying their lives, helping to get rid of their lonely life and unhappy events through this organization. They have, for the last few centries ,made it a rule to organize"Gyes"when they wish to do something to be done by Cooperation. To-day, the movement of Cooperatives, so far as village cooperatives, it stagnant, while "Gyes"are prosperous and popular among the people. While cooperatives help to promote the economic development,"Gyes"prevent rural communities from it. This research is based on such a view point in finding the causes of poverty of Korean rural Communities. These surveys were performed by the country agencies of O.R.D and the pioneer workers of A.C., and students and the writer of this paper. Surveys were made on 29villages and 266 various socio-economic organizations,among which were 210"Gyes,17 agricultural Cooperatives, 18 4H clubs and 26 another associations Every organization was surveyed,according to the schedule, made in advance, by interviewing the leaders of every organization. Followings are the Conclusions made from the result of this survey: 1.There are many socio-economic organizations in rural Communities. Every village has 9 organizations, on an average. Above all the organizations, "Gyes"are absolutely numerous and the majority of farmers have joined in "Gyes". This fact make us consider that"Gyes" are still most prosperous. 2. Among the many "Gyes", those for funeral rite, marriage ceremony and recreation are most of all. The reasons why farmers organize so many"Gyes" are that these events causes them formidable expenses and that farmers are indulged in phylosophy of uneasiness. 3. Some of "Gyes" inhibit outsiders from joining and some limit the qualifications of membership. From this it is learnt that Gye has more or less exclusive nature in itself. According to the results of survey,"Gyes"-having 10.29 members-occupy overwhelmingly large number. This suggests that Korean farmers are more used to Cooperate in groups of smaller number of membership than in those of large number. 4. Usually the oldest member is selected as the head of every organization and the rest are selected in turn as manager without respect to their managerial ability As one of the major causes of the poverty in rural communities, it can be said that they are usually administrated by the aged. This fact is typically found in the system os "Gyes" 5. Almost all of the "Gyes" have considerable real and personal estates. Every Gyes lent their estates to their members or outsiders to get interest of high rate than that of Current band rate. The members of "Gyes"are indifferent to the high rate of interest for increasement of the fund of "Gyes" because they do not sense the evil practices of wasteful expenditure of "Gyes" This situation have brought to Korean rural communities the lack of motivation for the increasement of productivity

集團飼育과 飼育環境의 變化가 돼지의 寄生蟲感染에 미치는 영향을 알아보기 위하여 糞便中의 蟲卵을 檢査했다. 光州와 順天, 務安과 靈光에 散在한 農家(274頭), 市道指定 種豚場(292頭) 및 企業養豚場(449頭)에서 飼育되고 있는 總 1,015頭의 돼지를 대상으로 하였으며 雌雄이 다 같이 포함되었고 年齡은 1個月未滿의 어린 돼지에서부터 成豚에 이르기까지 多樣했다. 糞便材料는 1982년 1월부터 6월까지 6個月間에 걸쳐 採取되었다. 그 結果를 요약하면, 總10種의 寄生蟲卵이 檢出되었는데 콕시듐의 감염율(58.6%)이 가장 높았고 그 다음은 豚蛔蟲(16.2%), 돼지腸結節蟲(10.5%), 란솜稈蟲(9.7%), 돼지鞭蟲(5.9%)의 順이었다. 寄生蟲感染率은 지금까지 보고된 것보다 낮았으며 약 30%의 돼지가 아무 기생충에도 감염되지 않았다. 農家에서 기르는 돼지의 寄生蟲感染率이 가장 높았고 그 다음은 種豚場의 돼지이었으며, 大單位養豚場의 돼지는 현저하게 낮은 감염율을 보였다. 돼지腸結節蟲, 紅色毛樣線蟲, 그리고 콕시듐의 감염율은 年齡의 增加와 함께 增加하였으나 돼지鞭蟲과 란솜稈蟲의 감염율은 그 反對의 현상을 나타냈다. 糞便中에서 外部寄生蟲(가루옹에科)의 成蟲과 蟲卵이 發見되었는데 이들이 飼料와 돼지에 미치는 영향에 관해서는 앞으로 追求해 볼만한 과제이다. To determine the effect of intensive pig husbandry on the prevalence of internal parasitism, fecal examinations were performed. During the period of January-June 1982, feces were collected from 1,015 pigs in Chonnam area: of these, 274 pigs were reared in village houses, 292 pigs in breeding piggeries, and 449 pigs in the intensive husbandry. Both sexes were included, and pigs' age ranged from less than one month old to more than 6 months old. Coccidia were the most commonly encountered parasites(58.6%),, followed by Ascaris suum(16.2%), Oesophagostomum spp.(10.5%), Strongyloides ransomi(9.7%) and Trichuris suis (5.9%). Evidence of intestinal parasitism was not detected in 30.1% pigs examined. Pigs of village houses had the highest infection rate(88.7%), followed by pigs of breeding piggeries(78.1%) and of intensive husbandry(53.1%). The results indicate that the unsanitary conditions contribute to the prevalence of parasitism in swine more than the crowding. The infection rates of Oesophagostomum spp., Hyostrongylus rubidus and Coccidia increased with age, while the opposite was the case with the infection rates of Trichuris suis and Strongyloides ransomi. External parasites and their eggs (Acaridae) were demonstrated in the feces of swine (1.1%) and in the feed (concentrates). Their effect on the pigs' body remains to be verified.

These studies were carried out to investigate the effects of rice straw on the growth status of rice plants and changes of chemical properties and to get the suitable method for improvement of newly formed paddy soil. The results obtained are summarized as follows; 1. Under application of rice straw with N-fertilizer to adjust C/N ratio, the deficiency symptom of nitrogen and growth inhibition did not appear and the plant height and the number of shoot were increased at the early growing stage. 2. The brown rice yield was increased 9 per cent in the rice straw 600kg/10a plot adjusted in C/N ratio, and on the other hand decreased 1 to 8 percent in the rice straw plots non-adjusted in C/N ratio. 3. When rice straw was applied, the contents of organic matter, potassium and silica in the newly formed paddy soil were increased. 4. In the paddy soil applied with rice straw, the contents of nitrogen, potassium, phosphate, magnesium and iron in the rice plant were decreased. On the other hand, the contents of calcium and silica were increased. 5. Rice straw was decomposed about 53 per cent submerged control plot, and 55 per cent in rice straw plot. 6. The total nitrogen in the buried rice straw was increased as high as 39 per cent whereas the hydrolyzable carbohydrate with 0.7 N-HCl in the buried rice straw was decomposed 46 per cent at the harvesting stage.

飽和粘土의 變形率 推定

李汶樹 全南大學校農漁村開發硏究所 1982 農業科學技術硏究 Vol.17 No.2

This paper treats the deformation characteristics rather than the shear ones. On the reconsolidated and remoulded saturated clay sampled from the downstream of Yeongsan river in Cheollanamdo, it is investigated that the prediction of strains will be possible based on the theory considering the effect of dilatancy among the several prediction theories 1) developed so far through the undrained and drained triaxial compression test. The conclusions analized are as follows. 1. It is confirmed that the stress paths obtained from the undrained triaxial test with constant cell pressure are similar one another, and state path normalized with Pe(mean equivalent pressure) is overlapped on the same locus, so that there exists a unique state path on the specimens used in this experimental study. 2. The volumetric strain due to the model based on the characteristics of the dilatancy effects is similar to the experimental observation. 3. The prediction of shear strain due to both the incremental theory and the volumetric strain 2) is similar to the experimental observation.

The PCV between age groups was lowest in the age group of 2 years(29.84ml/100ml). 4. Mean corpuscular volume(MCV) was 52.09(23.77-86.57) fl. whereas the MCV of adult cows 51.22(29.77-6.57) fl. Mean corpuscular hemoglobin(MCH) was 16.10(8.21-28.96) pg, whereas the MCH of adult cows was 15.54(8.21-28.96) pg. Mean corpuscular hemoglobin concentration(MCHC) was 30.90(17.35-53.57)g/100ml, whereas MCHC of adult cows was 30.35(17.35-53.57)g/100ml. The MCV, MCH and MCHC appeared to be higher in the calves and heifers than in the adult cows. 5. Most anemic cattle showed macrocytic, hyperchromic anemia. Various types of anemia were detected; microcytic(MCV 37.15 fl) hypochromic(MCH 12.35.pg); macrocytic hypochromic(MCHC 24.21g/100ml); microcyticfMCV 35.71 fl)hyperchromic(MCHC 40.83g/100ml). 6. Mean white blood cell(WBC) count was 10,186(3,200-31,600)/ l, which was high compared with other results. The WBC count between age groups appeared to be especially higher in the age group of 2 years(12, 647/yu.e) than in the other age groups. 7. Mean differential WBC count was lymphocyte 66.95(36-91), monocyte 3.08(0-12), neutrophil 25.69(2-54), eosinophil 3.84(0-18) and basophil 0.44(0-5%), respectively, while in the adult cows, it was lymphocyte 65.87(36-86), monocyte 3.15(0-9), neutrophil 25.84(6-53), eosinophil 4.73(0-15) and basophil 0.41(0-2)%, respectively. Lymphocyte count increased up to 1 year of age and thereafter it decreased with age, whereas the reverse was the case with neutrophil count. There was a negative correlation between lymphocyte and neutrophil counts. Monocyte and eosinophil counts tended to be slightly higher in the older age groups. 8. Mean platelet count was 252,429(93,000-964,000)/㎕; no differences were found in the platelet count between age groups. 9. Mean serum total protein(TP) content was 6.88(4.10-10.20)g/100ml, while the TP content of adult cows was 7.35(5.10-10.20)g/100ml. The TP content tended to increase with age. 10. Mean serum aIbumin(Alb) content was 3.43(2.00-4.40)g/l00ml, while the Alb content of adult cows was 3.51(2.00-4.40)g/100ml. The Alb content appeared to be lower in the calves and heifers than in the adult cows. 11. Mean serum globulin(GIb) content was 3.45(1.10-7.15)g/100ml, while the Gib content of adult cows was 3.84(1.40-7.15g)/100ml. The Gib conienc tended to increase with age. 12. Mean serum .albumin: globuIin(A/G) ratio was 0.99(0.40-3.33), while the A/G ratio of adult cows was 0.91(0.43-2.64). The A/G ratio tended to decrease with age. 13. Mean serum cholesterol concentration was 145.65(44.0-336.0)mg/100ml, whereas the scrum cholesterol concentration of adult cows was 180.93(46.4-336.0)mg/100ml. The serum cholesterol concentration increased up to 4 years of age and thereafter it decreased with age. 14. Mean serum glucose concentration was 46.00(27.0-96.0)mg/100ml, whereas the serum glucose concentration of adult cows was 39.61(27.0-65.0)mg/100ml, which was low compared with other results. The serum glucose concentration between age groups appeared to be especially higher in the age group of less than 1 year(58.07mg/100ml) than in the other age groups. 15.

The Na/K ratio between age groups appeared to be especially lower in the age group of less than 1 year(26.77) than in the other age groups. 23. The values of RBC count, Hb content, PCV, MCH and MCHC increased up to 15-20kg milk yielding group and thereafter they tended to decrease with higher milk yielding groups. In other words, there was a negative correlation between the values of erythrocytic series and milk production. 24. The leukocyte and lymphocyte count were a negative correlation with milk yield, while the neutrophil count was a positive correlation wirh milk yield. The monocyte and eosinophil count tended to increase as milk production increased. No relationships were found between the platelet count and milk production. 25. The serum total protein and globulin content tended to increase as milk production increased, while the reverse was the case with serum albumin content and A/G ratio. 26. The serum glucose concentration was a negative correlation with milk yield. The Serum cholesterol concentration tended to increase as milk production increased. 27. The serum calcium and inorganic phosphate concentration tended to increase as milk production increased, while the opposite was the case with Ca/P ratio. The serum magnesium concentration was especially lower in the highest milk yielding group than in the other milk yielding groups. 28. The serum sodium concentration and the Na/K ratio tended to increase as milk production increased. In other words, there was a positive correlation with milk yield. The serum potassium concentration tended to decrease as milk production increased. No relationships were found between the serum chloride concentration and milk production.

Present experiments were attempted to investigate the effects of several different. media and nitrogen sources for the mycelial growth of E. parasitica. chestnut canker fungus The results are summalized as follows: 1. On the culture media used in the experiment. mycelial growth rates of E. parasitica from 2nd day to 8th far after transmitting are increased nearly in line. and the rapidity of colonial spreads are increased in older as follows; soy-bean souse agar>potato-sucrose agar potato agar>Hopkin's agar 2. Colonial characters are thin and whitish appearance on soy-bean souse agar and Hopkin's agar media, on the contrary, on the potato-sucrose agar and Potato agar are thick arid yellowish-orange, and viscosious pycnespore-masses are produced abundantly. 3. Nitrate nitrogen is better utilized among the nitrogen sources tested and the rates of their utilization are put in order as follows; KNO₃>(NH₄)₂S0₄, asparagine>NH₄₄NO₃>urea. 4. Nitrate nitrogen and ammonium nitrogen are utilized well by the E. parasitica. when the nitrogens of both forms exist separately in each medium, but when both. forms exist in the same medium, they are utilized poorly because of occurring the antagonism between the nitrate and ammonium nitrogen.

流出解析에서의 有效雨量分離에 關한 硏究

嚴柄鉉 全南大學校農漁村開發硏究所 1982 農業科學技術硏究 Vol.17 No.2

In the runoff analysis, it has been recognized that a precise estimation of effective rainfall leads to a more accurate runoff analysis. Up until now, many methods for estimating effective rainfall have been proposed, however, none of them were evaluated as being adequate. A method utilizing the relation between cumulative rainfall and cumulative water losses is generally used as the most rational method. However, even this method has a crucial drawback in that the relation between cumulative rainfall and cumulative water losses is not always identified as a single-valued function because of the influences caused by the soil moisture condition in the catchment, differences in rainfall patterns and so on. In this paper, the function, Ld=(Smax-qb/K). (1-e -ap) is proposed, in which cumulative water losses (Ld) is related by cumulative rainfall (p) and discharge at the beginning of the storm (qb), to deal with the above problem (Smax,K and a are the constants inherent in the catchmets). Applying this method tothe hydrological data of the Geum River basin, Korea(Area = 7,179 m2) and the Kamigamo experimental catchment in Kyoto, Japan (4.39 ha), the adaptability of this method is higher than that of the previous method which is in ordinary use (Figs. 11, 12, 13 and 14). That is to say, the deviation of data is diminished and the relative srror decreases from i6% to 7% in the Geum River hasin and from 23% to 16% in the Kamigamo experimental catchment (Tables 3 and 4).
