This study was carried out for comparative test of growht and yield difference about soybean in crop rotation system and results obtained were as follows. 1. Soybean should be grown well in the fallowing than in double cropping land for a year. 2. The growth of soybean variety Hill planted in row spacing and after cropping ground were slender and grain yield in alley were reduced but increased in after land as potato cultvated land. 3. Yield difference in rotation system about four variety showed Hill in fallowing, Kyungnaml in row spacing land, Haman and Kyangyo in after crops were higher.

Plastic products are producted more than 70% of total processes in the injection molding. The injection molding process has 4 processes such as filling, packing, cooling and ejecting. It spends most of times in the cooling process. Therefore, it is important to control the mold temperature in producing plastic products. The time and system of cooling affect the product's quality and productivity. Especially, cooling time has about 60% of total injection cycle time. Therefore, we can improve a productivity by shortening cooling time. In this study, it was made a comparative study about cooling of linear channels and baffles and observed the variation of mold temperature on the coolant's temperature. As the result, the linear channel's cooling rate had faster than baffles and as coolant's temperature was increased, difference of cooling time was increased. Result of this study will be used widely to design for cooling system of injection mold.

This paper describes the process of structure analysis and injection molding analysis to manufacture the forming injection dies for huge glass insert. Factors such as filling time, filling pressure, material temperature, shrinkage, warpage were investigated by using the analysis software, Moldflow. Runner system and cavity structure were designed and manufactured through the results of deformation analysis data for glass insert. Filling time and filling pressure were analyzed in 3.756sec and 43.37MPa.

There occur not only many problems in the injection process but also low quality productivity due to the injection conditions of various injection factors. Injection molding process factors such as molding temperature, injection pressure, flow rate and flow velocity, must be controlled properly in filling and packing phases in the injection molding process. In this study, effects of these factors on the injection molding were investigated through the flow analysis for the holding pressure affecting cooling time. Results of this study would be helpful to setting of holding pressure for optimization of forming condition in order to reduce cooling time in injection molding.

麥酒麥栽培의 秋播 및 春播比較試驗

文永培 진주산업대학교 1981 論文集 Vol.19 No.-

生産에 있어서 秋播와 春播의 成績을 종합 검토하여 보면 다음과 같다. 1) 秋播의 理想的인 播種期는 10月 25日∼11月1 播種이 年次差異가 적고 무난하다고 생각하다. 2)春播에 있어서는 解多과 더불어 可能한 早期播種을 서둘러야만 收量 및 品質이 秋播보다는 부진하나마 어느 정도 보장될 것이 確實시 되었다. 3)요컨대 麥酒用 栽培를 前載로 栽培할 때는 品種 및 收量面을 고려하여 볼 때 晩播 및 春播栽培은 可能限 하는 것이 有利하다고 생각된다. 4)秋播에 있어서 11月 20日 晩播는 春播區의 2月 20日에 比하여 年次에 따라 差異는 있으나 晩播보다는 오히려 早期春播를 實施함에 有利할 것으로 展望되었다. This study was conducted to find out the qualities and yields of the malting barley sowen in the different season and the results are summarized as follows: 1. The ideal seeding time in fall planting was from October 25 to november 1 and the small variation of the malting barley’s quality and yield was observed in every year. 2. The yields and qualities in spring planting were worse than those in fall and in spring planting the earlier seeding plots were better than those in the late seeding plots. 3. It was considered that the late seeding in fall season and the early seeding in spring season for the malting barley were useful. 4. The yields and qualities sowen between november 20 and february 20 had a little variation, but it was also considered that the yields and qualties in spring planting were more useful than those in fall.

文永培,金鎭雨 진주산업대학교 1980 論文集 Vol.18 No.-

大豆의 單作栽培(早播區)와 麥後作栽培(晩播區)에 있어서 栽植密度를 各各 달리 했을때 大豆의 生育 및 收量差를 調査하므로서 作付體係에 따른 栽植密度를 究明하기 위하여 本試驗을 實施한바 몇가지 結果를 얻어 要約하고져 한다. 1. 播種期間의 開花에 所要된 日數는 單作早播區(5月 20日 播種區)가 59日, 晩播區(6月 20日 播種區)는 38日이 소요되어 晩播할수록 開花日數가 短縮되었고 成熱日數도 역시 같은 傾向이었다. 2. 播種期에 관계없이 密植일수록 莖長을 길어지고 反面 分枝數는 적은 傾向이었다. 3. 收量에 있어서는 早播區가 晩播區에 比하여 增收되었고 특히 早播區는 疎植할수록, 晩播區는 密植에 가까울수록 增收되는 結果를 보였다. This experiment was conducted to determine the feasible population density of soybean treated with the different population densities and sowned in the two difference seasons in the early spring and in the late spring after harvest of wheat and barley and the results were as follows; 1. The reguiring days to flowering of the soybean took 59 days in the treatment sowned in the early spring and 38 days in the treatment sowned in the late spring. The later we planted, the shorter the days to flowering became. In the case in the days to maturity, it showed similar trends in response to the days to flowering. 2. The more the populations increased, the longer the length of leaf became, but the number of branches became, shorter and shorter. However, it had nothing to do with the different sowing season. 3. In the treatment sowned in the early spring, the yields of soybean was increased than those in the late spring. Especially, the more the population density in the early spring and the less the population density in the late spring increased, the more the yield was high.
