GAMMA 네트워크를 이용한 ATM 스위치 구조에 관한 연구
김근배,황성호,송주빈,이종현,임해진,박병철 한국통신학회 1991 韓國通信學會論文誌 Vol.16 No.11
본 논문은 입력과 출력 사이에 다중경로가 제공될 수 있는 GAMMA 네트워크를 이용한 새로운 ATM 스위치의 구조를 제안한 것이다. 제안된 구조는 BANYAN 네트워크를 기본으로 한 여타 ATM 스위치와는 달리 블러킹 문제 해결을 위한 Sorting 네트워크의 필요성을 배제시킨 구조로서 전체 스위치 구조가 축소될 수 있는 스위치이다 또한 시뮬레이션 기법에 의한 제안된 스위치의 성능 평가를 통해 본 연구의 타당성과 그 효율성을 검증하였다. In this paper, we proposed a new ATM switch structure which is based on the GAMMA network, proving multipath between an input and an output port. The size of the proposed new ATM switch will be smaller than the switches based on the BANYAN network, which includes the Sorting network to resolve the blocking in the switch fabric. Also, the validity and the utility of the proposed switch structure is verified through a simulation method.

1990년대의 한국 전문대학의 공예 및 디자인 학과의 교과과정 연구

AbstractIn the 1990s, The phenomena of local-preponderance of technical college don't better than before. The curriculum of industrial arts and design parts can't be seen many difference in the comparison with 1980s.In the high-developing industrial societies, new curriculum development must rapidly be ready for industrial arts and design studies as well as computer education and after school is over, at once students must be employed.To do so, it can be necessary to study curriculum of job-site disposal and new curriculum should be developed for school and industries to cooperate each other.

金根培 建國大學校生活文化硏究所 1989 생활문화ㆍ예술논집 Vol.12 No.-
As commodity export have been increasing due to korean high growth of economy. the improving problems of Industrial Design to support it and the security of excellent designer become necessary. The improvement of cultural life environment and the industrial development was influenced by the design education in university in a contempory society. In the design education of our country its curricula was reorganized through several trial and errors. And many efforts was made to heighten the equalization of higher eucation and the level of college education through the new fostering of college education project in 1980. At this time that all has been dividing into specialization in a contemporary society. design education have to grope for the characteristic of design education by harmonizing liberal arts cultural studies with a major. For this purpose design education should be settled down by means of long-term close plan and governmental active support investment for design development by industrial bussiness. the efforts of design workers. As the establishment of design conception and the setting of reasonable educational objective. the educational system, its curricula and educational contents are settled. the study to carry them into effect is necessary. Even though education authorities have recently tried equalize college education by means of the number limit system of graduation and the full-time system of school, carry out design education to train up excellent designers, the could not achieve their goals therefore, as the regular four-year course system universities carry out the socially required design education ranging from their own entrance examinations to teaching methods by university. they should train up superior craftmen and industrial designers. If the improvement of better living environment and high industrialization is to be continued, the study should be to educate on design according to new educational methods.

The purpose of this study is to investigate the basic data such the total, the daily maximum, and the peak stage of consumptive use of water and also the soil moisture extraction pattern for irrigation plan of tobacco during the growing period. The plots at which this study was conducted are divided into three fertilization levels of 30g, 60g, and 90g. Each block for three levels is divided as vinyl mulching and irrigation plot, vinyl mulching and nonirrigation plot, and nonmulching and irrigation plot. The results obtained are summarized as follows: 1. The evapotranspiration amount of mulching-irrigation plots are similar to that of mulching-nonirrigation plots. While, the evapotranspiration amount of mulching plots are different obviousely from that of nonmulching plots. Therefore, a significance was recognized between the mulching plots and the nonmulching plots. 2. The amount of evapotranspiration in case of 60g and 90g fertilization level was larger than that of 30g. But the 60g plots and the 90g plots showed little differences. 3. In the total amount of evapotranspiration for each of the experimental plots during the growing period, nonmulching-irrigation plot showed the largest value of 332.9mm, second the mulching-irrigation plot, 284. 9mm, and the mulching-nonirrigation plot, the smallest as 255. 9mm. 4. In the monthly average amount of evapotranspiration for each of the treatment plots, the mulching-irrigation the mulching-nonirrigation, and the nonmulching-irrigation plot showed 3. 6mm, 3. 2mm and 4. 2mm respectively. The daily maximum amount of evapotranspiration showed 5. 1mm, 4. 5mm, and 6.4mm for the mulching-irrigation, the mulching-nonirrigationl, and the nonmulching-irrigation plot respectively. 5. It was confirmed that the higher correlationship exists between the weight of dried leaves and the amount of evapotranspiration, and between the weight of dried leaves and the coefficient of evapotranspiration with the function of logarithms. The coefficient of evapotranspiration have a tendency to increase in proportion to the leaf area index. 6. The maximum coefficient of evapotranspration and the largest leaf area index showed 1. 45 and 5.5 respectively. The stage appeared maximum values was assumed to be before and after flowering. 7. The soil moisture extraction pattern has changed by the depth of root zone for the tobacco's growing. The soil moisture extraction influenced on the 20cm depth of soil after 15 days passed, the 30cm depth after 25 days passed and the whole root zone after 45 days passed from planting. It was shown in the only mulching-irrigation plot after S5days passed from planting that the rate of soil moisture extraction of 20cm layer was larger than that of 10cm layer.
