濕田에 있어서 물管理에 關한 作物學的 硏究 : 落水處理가 水稻의 光合成에 및이는 影響 The effect of the surface drainage on the Photosynthetic activity in rice Plant

蔡殷錫 全北大學校 1966 論文集 Vol.7 No.-

1. Authors investigated an in fluence of the surface drainage on the photosynthetic activity in race field. 2. The yieldof rice plants was increased by the surface-drainage treatment given during a period from the end of fertile tiller formation until the soil moisture content decrease to 70% 3. According to the analysis of havested materials, this yield-increase was chiefly dud to the increase in ripened in repened grain number ratio of ripened grains to total grains in an ear. and weight of 1000 unhulled Kernels. 4. To know the reason for this. authors measured the apparent photosyn the tic activityof rice population in field, and discussed the relation between the Photosynthesis and other charactersin rice plant. 5. The total area of riceplant in this dsainage-plot was generally inferior to that of the constantly water-logged plot (control plot) both in the draining stage and in the subseguent irrigatings tage. 6. Connected with the total leaf area. the light transmission rate in the drainage-plot inas almays inclined to be higher than that of the control-plot. 7. The water content of rice plant was lomer in the drainage-plot thanin the control plot. Not only in the draining stage but also in the subsquent irrigating stage. 8. Though the photosynthetic activity per Unit area either of rice leaves or of the field was depressed by such draining treatment. it was promoted by the subsquent irrigation. 9. This superiority of the photosynthetic activity in the drainageplot lasted until the ripening stage and attributed to the yield incvease. 10. Although it has been reported by some researcher that the pho tos ynthetic activity per unit leaf area has highly positive correlation with the water content in rice leaf blode? but in this study, the correlation between them was partially disturbed because other factors caused by drainage treatment might presumably benefit the photosynthetic activity.

We extend the ranges of the vacuum standards to 10^-6 Pa by injecting the gas flow into the lower vacuum chamber of the orifice flow type vacuum standards system. The systematic error of the vacuum measurement has been reduced by measuring temperature accurately by reducing leak rate of the flowmeter and by attaching the ballast tank to flowmeter. We measure N_2, He and Ar gases for the sensitivity of nude ionization gauge for the check of the vacuum accuracy. The results are compared with the result of other research institute.

Long term occupational exposure to solvent mixtures may cause adverse effects to the central nervous system with neurobehavioral symptoms. And some organic slovents have been suggested to cause impairment of tuberoinfundibular dopaminergic activity and neurochemical mechanisms controlling pituitary secretion. For the purpose of assessing neuroendocrine effects in occupational solvents exposure, hormonal study settings (shoes-manufacturing industry & fishing products industry) and compared with nonexposed controls(33 men, 85 women). Male workers exposed to solvent mixtures had significantly lower plasma level of follicle-stimulating hormone(FSH) than nonexposed male controls. While female workers exposed to solvent mixtures had significantly lower plasma levels of growth hormone(GH), and thyroid-stimulating hormone(TSH) than nonexposed female controls. The results of significant decrease in plasma concentrations of pituitary hormones(FSH, GH, and TSH) in workers exposed solvent mixtures indicate that occupational exposure to solvent mixtures may induce neuroendocrine effects through an effect on hypothalamic pituitary axis.

For the purpose to estimate the exposure levels of heavy metals and to present a basis of occupational health managements to the industrial workers exposed to heavy metals, this study conducted to know the lead and chromium levels of whole blood of industrial workers. The study population were divided into three groups to the exposure levels ; directed exposure group, indirect exposure group and non-exposure group, and the sample number of workers who exposed to lead were 80, chromium were 77, and control group were 31. The contents of lead and chromium were analyzed by atomic absorption spectrophotometer. The results were summerized as follows : 1. Sex distribution of studied group were 77.1 % in male, and 22.9 % in female. Age distribution were 74.4% in 30-49 age group. The work in years were 43.1 % in 5-10 years, 29.8% in 1-4 years. 2. Mean blood level of lead were 33.53㎍/㎗ in direct exposure, 23.84㎍/㎗ in indirect exposure group and 11.77㎍/㎗ in control group. 3. Mean blood levels of chromium were 1.9㎍/㎗ in direct exposure, 1.51㎍/㎗ in indirect groups and 0.95㎍/㎗ in control group. 4. Mean lead levels of direct exposure group was higher in male than female as 36.44㎍/㎗, 27.35㎍/㎗ respectively, but there was no difference in indirect and control group by sex. Mean chromium levels of direct exposure group were higher levels 2.26㎍/㎗ in female than 1.84㎍/㎗ in male, but there were no difference in indirect and control group by sex. 5. The age group of 29 or younger among the direct exposed had high level of lead and chromium as 35.7㎍/㎗ 2.41㎍/㎗ respectively, but that age group had no evident difference in the level of lead and chromium among the indirect exposed and non-exposed.

沈銀淑,兪鎭采 충북대학교 농업과학기술연구소 1989 農業科學硏究 Vol.7 No.1

The slopes, cultivate ratio and conditions of soil are settled and then agricultural region classified by the altitude in Chungbuk area. Because of the ranges of the Mountains of Soback to the east the altitude is high and the plains is developed to the west. The Interior of the Centural Area of the West (Ginchon, Womsong, Chungju, Jungwon) and the West Interior of Soback Mountains(Chungju, Chungwon) are high cultivate ratio and proper for the good conditions of production. On the other hand, the Taeback area (Gaesan, Tanyang) with low temperature is mountainous area, and so the altitude is high and cultivate ratio is low. The climate of this area have the feature of low temperature in the high mountains, that is why the conditions of production is disadvantage. The Soback Mountainous area(Kwesan, Bowuen, Okchon, Youngdong) is semi-mountainous area, and so cultivate ratio is low, the condition of agricultural production is a little disadvantage. The zone of life and the social-economic conditions is reflected by the agricultural areas mentioned above. Namely, the cities are developed in the advantageous area of agriculture and social-economic conditions is better. And also in the management-indicate-analysis the differences of the natural condition is reflected by the section of the region. In analysis of the specialized items and the development stage each farm in its scale has come the resemble concussion. Although the specialized items are same the meaning is different on the distribution of farm scale. We may say that the specialized regions living many farms with more scale which can suffice the farm household cost and can remove the differences of income between city and country. Owing to the limitation of material data I cannot reflect the tendency of the latest, but I can conclude that agricultural system of Chungbuk must be done to the following directions. First : When we deal with agricultural management as a matter of region, We should not disregard production policy of each items and then improve the structure of agriculture and product system in this region. Second : Laying stress on the items which are glowing the farm management scale, We should organized the system of agricultural production. Third : As the investment of industry to magnify the management scale in the IGP region is the modernization of facilities, the introduction of machine and strategic investment of economic project is valuable. The investment should be put in advance in the FGP and IGP in order to improve the infrastructure of agriculture for the agricultural foundation and social overhead capital.

「서동요」의 형성과 그 예언적인 힘의 유래 : 「삼공본풀이」와의 관련을 중심으로

The aim of this thesis is to reveal the formation of "Seodongyo(薯童謠)" and the source of its prophetic power. Until now the relation between "Seodongyo(薯童謠)" and "Samgongbonpuri(三公본풀이)" was ignored. Consequently a folk song was believed to be the origin of "Seodongyo(薯童謠)," and an artful design of Seodong(童謠) was regarded as the source of its prophetic power. Now this view must be corrected. "Seodongyo(薯童謠)," has two important elements. One is 'rumour' which caused Seonhwagongju(善花公主) to be expelled, and the other is 'love' which caused her to success. "Samgongbonpuri(三公본풀이)" also has two elements similar to those. After all "Seodongyo(署童謠)" was formed by reducing "Samgongbonpuri(三公본풀이)." In the context of "Seodongyo(薯童謠)" Seodong(薯童) and Seonhwagongju(善花公主) are objectified. So "Seodongyo(薯童謠)" is the wishful utterance of storytellers who see them objectively. After all the source of prophetic power of "Seodongyo(薯童謠)" is the story of "Samgongbonpuri(三公본풀이)" or the desire of storytellers.

For the purpose of promotion of mental health in the rural elderlies, we surveyed 506 elderlies by means of Mini-Mental State Examination(MMSE) for evaluation of cognitive functions. We assesed degree of cognitive function impairments and association between cognitive function and socio-environmental conditions. The results were as follows : 1. Proportion of severe and mild cognitive function impairments were increased as incresing age, and mean scores of MMSE became decreased significantly among them(P<0.001). 2. In female, rates of severe and mild cognitive function impairment were high and mean scores of MMSE were significantly lower than male(P<0.001). 3. In widow group, proportion of severe and mild cognitive function impairment were high and mean scores of MMSE were significantly low(P<0.001). 4. As decreasing familly numbers, proportion of severe and mild cognitive function impairment became high and mean scores of MMSE were significantly low(P<0.01). 5. In physical handicaped group, proportions of severe and mild cognitive function impairment were high and mean scores of MMSE were significantly low(P<0.001). 6. In low scores of physical ability group, proportions of severe and mild cognitive function impairment were high and mean scores of MMES were significantly low(P<0.001). 7. Most item-scores of MMSE were significantly correlated. 8. In stepwised multiple regression analysis, age, existence of physical disorder, sex and scores of physical ability were selected highly correlated variables and power of explanation was 0.1528.

여말선초의 시화에 나타난 기(氣)의 성격 변화와 그 의미

鄭雲采 건국대학교 인문과학연구소 1998 인문과학논총 Vol.31 No.-

The aim of this thesis is to reveal the change of the concept of Ki(氣) in Sihwa(詩話) and its meaning. Until now the change of the concept of Ki(氣) in literary criticism was ignored. Consequently the understanding of the relation between literary and society was superficial 《Bohanjib(補閑集)》, the Sihwa(詩話) which is written in Koryeo-Sidae(高麗時代), emphasizes the characteristic traits of Ki(氣) itself and the process of their growth. Therefore Ki(氣) itself is the criterion of a literary work's worth. 《Donginsihwa(東人詩話)》, the Sihwa(詩話) which is written in Joseon-Sidae(朝鮮時代), emphasizes the external source of Ki(氣) and the appearance of it. Therefore the external source of Ki(氣) is the criterion of a literary work's worth. These facts mean that in Koryeo-Sidae(高麗時代) the aesthetic sense of a work is the criterion in literary criticism and in Joseon-Sidae(朝鮮時代) the utility of a work is the criterion in literary criticism.
