송원섭,진영욱,김동철,우 서 順天大學校 1997 論文集 Vol.16 No.1

유자(Citrus junos)의 부정배는 자연조건에서는 주심조직과 배낭근처에서 발생하였으며 부정배로 발육될 시원세포들은 매우 큰 핵과 세포질로 충만되어 있고 주로 배낭근처에 있는 주공측의 주심조직에서 발생되었다. 기내배양 조건에서는 자연조건에서 보다도 훨씬 많은 부정배들이 배낭내에서 관찰되었으며 이러한 부정배들은 대부분 배낭과 밀접해 있는 주심세포층으로부터 발생하였다. 또한 몇몇 부정배들은 주심조직에서 직접 발생하는 것이 관찰되었다. Adventive embryo usually occurs inside the embryos ac nucellar tissue in the in Vivo state. Initial cells to be developed in to adventive embryos were conspicuous with large nucleus and dense cytoplasm, and arose mainly from nucellar tissue or from integuments. In the in Vitro culture, much more embryos were observed in the embryo sac. than in the in Vivo conditions, and embryos seemed to arise from the nucellar cell layer lining the embryo sac. Some of the adventive embryos were observed occurring directly from the nucellar.

新梢頂端培養에 의한 대추나무(Zizyphus jujuba Miller)의 callus로부터 植物體 再分化

宋沅燮,金鎭洙,劉成吾 圓光大學校大學院 1991 論文集 Vol.8 No.-

Organogenesis from callus induced from shoot tip in vitro cultured was examined with using different strength of MS medium containing various concentration of different plant growth regulators alone and its combination in jujube (Zizyphus jujuba Miller). Callus induction was favorable in the treatment of concentration of 2,4-D 1.0, 0.3mg/1 adding on MS medium. Favorable shoot proliferation from callus subcultured on medium for shooting appeared in the treatment of 0.5mg/1 BAP alone adding on 1/2 MS medium. For rooting induction 1/2 MS medium supplemented with the combination of 0.5 or 1.5mg/1 IBA and 0.1, 1.0mg/1 BAP was most effective but 1/2 MS medium containing IBA alone had little effect.

The purpose of this study is to clarify the effect of the monomer ratio on properties of the polymer-modified mortars using methyl methacrylate-ethyl acrylate latexes, and to obtain basic data necessary to develop appropriate latexes for cement modifiers. This paper deals with the effect of the monomer ratio on the typical properties of polymer-modified mortars with methyl methacrylate-ethyl acrylate latexes. The polymer-modified mortars using MMA/EA latexes are prepared with various polymer-cement ratio, and tested for strengths, water absorption, and chloride-ion penetration depth. The test results indicate that the monomer ratio is very important factors to characterize the strength properties of polymer-modified mortars, but the water absorption and chloride-ion penetration depth are influenced by polymer-cement ratio rather than monomer ratios.

楊雲燮 群山大學校 1982 論文集 Vol.4 No.-

Management is the dynamic force which converts human and nonhuman resources into organizational Performances. It is a process which integrates previously stated resources into something that is greater than the mere sum of its parts. So the role of management is to facilitiate the effective and efficient attainments of organizational goals and personal needs of its members. Today's manager, however, has faced with difficulties in the light of changing environment, and it is his agency to deal with the change and must cope with the environment it has set in turbulent motion. And these difficulties should be solved not by the external factors, but by the internal factors such as motivation, participation in management and self-goal setting or self-control etc. Management by objectives (MBO) is best known as a system which encourages increased participation in management of the organization at all levels and emphasizes accomplishments and results and also a system of management designed to faciliate planning and organizational control, organizing and assigning tasks, problem-solving and decision-making, and motivation and self-control, as well as other important functions and activities. Activities such as performance appraisal, manager development, Compensation and manpower-planning can be meaningfully integrated into this system. The writer assumed that the actual application of this MBO system in organization through member-control by planned objective members and management productivity by objectives should be very helpful trying for the growth of Enterprise, so he studied the above title as the following contents.
