Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

김경태,신현익 금오공과대학교 2008 論文集 Vol.29 No.-

Educational facilities and other school buildings are generally planned and designed by the district educational office. For this reason, actual users, students, teachers and regional residents are excluded at the acquisition stage (Planning, design, and construction) of the new school building. As a result, this research identifies 'participants' needs for the multi-purpose auditorium from each stakeholder involved in designing, constructing, maintaining and using it. The research was conducted by adopting the Multi-Phase Quality Evaluation (MPQE) tool kit which is able to integrate building needs from designers, students and teachers, regional residents, the principal and the facility manager of the school. This research focuses on multi-purpose auditoriums from elementary to high school in Gumi-City

This paper considers identical parallel machine scheduling problem. Each job has a processing time, due date, weight and family type. If a different type of job is follow by prior job, a family setup is incurred. A two phased heuristic is presented for minimizing the sum of weighted tardiness. In the first phase, using rolling horizon technique, group each job into same family and schedule each family. In the second phase, assign each job to machines using schedule obtained in the first phase. Extensive computational experiments and comparisons among other algorithms are carried out to show the efficiency of the proposed algorithm.

엄제현,박동기,김익수,성일용,김종윤,김진석 三陟大學校 産業科學技術硏究所 2003 産業科學技術硏究論文集 Vol.8 No.1

The applicability of a sulphation-floatation process was considered in order to depress of galena in a mineral processing process of complex sulphide ores. The galena will be depressed in the floatation step because of the formation of a PbSO₄ film on the surface of galena. when a PbS bulk concentrate is treated with sulphuric acid. The optimum conditions of the sulphation treatment for depressing galena were found to be 30%. and about 5 minutes of retention, with 18 Vol. % H₂SO₄. under these conditions. galena was sulphated only slightly and thus in complete depression in the floatation.
