이학수 대구효성가톨릭대학교 현대사상연구소 1999 현대사상연구 Vol.9 No.-
This study has the focus on interchange relations and cooperation between south and north in the governmental level. And then I analyze the following fields here. ① background, objects, scope and methodology as a preface ② environmental analysis on interchange relations and cooperation ③ criteria and principles on interchange relations and cooperation ④ case analysis ⑤ prospects and conclusion Above all, the ultimate findings are that it is important to exist the interchange relations and cooperation between two governments, and that our government must have a highly diplomatic strategies, north Korea's government must have sincere attitudes rather than past. If we all have the above circumstances, Korea's unification will be completed before long.

施肥量,栽植密度 및 收穫時期가 담배 잎蛋白質 生産에 미치는 影響
李鶴洙 충북대학교 엽연초연구소 1993 煙草硏究 Vol.14 No.-
Effed of the amount of fertilizer, plant density, and harvesting time on the production of tobacco leaf protein and fresh biomass were investigated. Flue-cured tobacco(N. tabacum, L., cv, NC 82) seedlings were transplanted in the field dressed 200 kg N per ha at 1×105, 3×105, 5×105, 7×105 plants per ha, and were harvested at the time when 6 and 10 weeks after transplanting, respectively. Harvest at 10 weeks after transplanting increased greatly number of leaves per plant and fresh weight of a plant, percentage of senescent leaf weight, but significantly decreased fresh weight of a leaf and total protein contents g-1 fresh weight of the leaf and stalk over the amount obtained from the harvest at 6 weeks after transplanting. Also, fresh leaf numbers of a plant, fresh weight of a leaf and of a plant, and total protein contents g-1 fresh weight of biomass were more decreased, but the percentage of senescent leaf weight was remarkably increased under higher plant density. Therefore, it was seemed that harvesting at 6 weeks after transplanting under 1×105 plant density per ha is more effective for producing higher yield of biomass and protein per plant than 10 weeks harvesting with 7×105 population per ha. But, a trend was observed that biomass and protein yield per ha are positively correlated with plant population, and interrelated significantly between harvesting time and plant density. Biomass yield per ha was the greatest at 7×105density(80.5t), but the peak of protein yield was at the near of 5×105 population(2,454kg as total protein) per ha on the regression curve. If was assumed that if tobacco plants are transplanted under 5×105 planted density at the mid of May, and thereafter harvested at 6 weeks repeatedly during the growing season, it is possible to harvest 2~3 times per year, and to yield more 6,024kg of total protein and over 140 metric tons of fresh biomass ha-1 year-1 statistically in the Korea tobacco growing regions.

이학수 韓南大學校 2007 論文集 (인문·사회·자연과학·공학) Vol.37 No.-
Bridges are investigated to study the effects of negative reaction forces. The parameters considered in this study are span lengths, angles of curvature, and the number of shoes. Midas/Civil computer program was used for the analysis of the curved bridges. The analysis results show that negative reaction forces are not created with one shoe installed. It is also concluded that the increasing ratio of negative reaction forces becomes larger, as the angles of curvature increase, and the elongation of span lengths turns out to increase the magnitudes of the uplift forces.

李學守 대구효성가톨릭대학교 1986 연구논문집 Vol.32 No.1
In this study general theory about organizational behavior is reviewed as an introduction and a frame work of analysis to analyze administrative phenomena and behavior. The purpose of studies to administrative behavior is to be established the development to organizational change and development has three dimensions, that is, individual dimension,. Organizational sturcture and goals have been relationed to organizational behavior. This paper is composed of following chapters. Chapter one is a step on an introduction which defines scope and analytic objects about organizational behavior. Chapter two is a step on theoretical analysis about three dimensions of organizational behavior, and this analysis is a framework about organizational behavior. Chapter three is a conclusion about this study. The ultimate finding of this study is that an analysis about organizational behavior is useful to behavior studies in administrative phenomena.

李鶴洙 충북대학교 엽연초연구소 1983 煙草硏究 Vol.10 No.-
The effects of method and fluid for homogenization, temperature and duration of incubation, and temperature in dehydration with a convectional drying oven, which are considered as important factors in HLC process, on the physicochemical properties of the final products from bright tobacco have been investigated. Homogenization in a commercial-size Waring blender after Food choppering over homogenization in Food chopper only decreased reducing sugar, starch, protein-N and specific gravity, whereas 0.025 M phosphate buffer solution added at the time of homogenization increased crude fiber and total volatile bases. Incubation at 40℃, and incubation for 48hr., individually, reduced reducing sugar, total -N, protein-N and total volatile bases. And then, dehydration at 120℃ over 80℃ decreased nicotine, reducing sugar, starch, petroleum ether extracts. In consequence of the effects from above and from interactions between factors, it is regarded conditions of homogenization and dehydration as more significant factor effects the quality of the final products than conditions of incubation in HLC process.
