황성호,오주현,임해진 三陟大學校 1999 論文集 Vol.32 No.1

An ATM multicast switch which can effectively accommodate diverse classes of traffic, is the core component of broadband ISDN. In this paper, we proposed a new call scheduling algorithm assigning priority according to the quality of service under the diverse traffic environment in multicast switch. The algorithm presented in this paper is using unfairness of switch structure, and delay-sensitive traffic may be given the high priority such that it can be transmitted as soon as possible. Also, we proposed a new hardware structure for the algorithm which can be constructed with combinational logic gates and it is beneficial for high-speed operation and VLSI implementation. The results of simulation for performance evaluation show that mean waiting time of delay-sensitive call is considerably reduced.

This study examines teachers' and students' perceptions on the quality of good secondary English teachers in Korea and provides suggestions for the standard of what makes a good English teacher. Through the questionnaire, the researchers collected data from 115 English teachers and 367 students at middle and high schools. The questionnaire consisted of 39 items asking what quality English teachers need in terms of language instruction (English ability, teaching skills, and interactive skills), personality, and assessment. Teachers and students showed significantly different perceptions of English teacher's quality depending on their current teaching/learning levels. Based on the results of the current study, the researchers suggest that more empirical studies like this current one are needed to develop valid standards of a good secondary English teacher's quality in the future and to apply them into teacher selection and teacher training.

본 연구에서는 교사-유아 간 애착안정성 정도에 따라 유아의 스트레스 정도 및 유아의 스트레스 대처행동에 어떠한 차이가 있는지 알아보고자 하였다. 연구 문제에 따른 연구 결과는 다음과 같다. 첫째, 교사-유아 간 애착안정성 정도에 따른 유아의 스트레스 정도에는 통계상 유의미한 차이가 없었고, 유아 스트레스 하위 영역인 교사, 또래, 학습 환경에서도 통계상 유의한 차이가 없는 것으로 나타났다. 다만 학습 활동영역에서 교사-유아 애착안정성이 낮은 유아 집단이 높은 집단보다 스트레스를 더 많이 받는 것으로 나타났다. 이러한 결과는 교사-유아 애착안정성 정도에 따라 교사, 또래,학습 환경 요인과 관련된 유아 스트레스에 차이가 없으며, 교사-유아 애착안정성이 높을수록 유아가 학습활동 요인과 관련된 스트레스를 덜 받는다는 것을 알 수 있다. 둘째, 교사-유아 간 애착안정성 정도에 따른 유아의 능동적, 수동적, 신비적 스트레스 대처행동 양식에서 통계상 유의한 차이가 나타났다. 교사-유아 간 애착안정성 정도가 높은 집단이 능동적 대처를 더 많이 하고, 교사-유아 간 애착안정성 정도가 낮은 집단이 수동적 대처와 신비적 대처를 비교적 더 많이 한다는 것을 알 수 있다. Due to lack of systemic program regarding physical activity in children, the study is to identify the constitution and development of the Natural Physical Activity Program by offering environmentally friendly elements such as wind, sun, mountain, sea, river, tree, flower, field for children. We expect children to learn the relation with nature, respect for life, understanding and love, importance of working together, and etc. The research questions for the purpose of this study are as followed: First, this study is going to identify the overall awareness and its needs of the Natural Physical Activity Program among preschool teachers. Second, we will look over how we can develop such program for preschool teachers. And a direction proposal on Natural Physical Activity Program. About 250 preschool teachers resided in Busan and Gyug-nam province were urged to participate in a research questioning their awareness and needs of the program. Among 250 preschool teachers, we choose 20 of them to interview about the goal, plan and development direction of the program. The result of the study is following as: First, most of the preschool teachers have a positive view on the Natural Physical Activity Program, and they agree that the program is highly needed to use. However, it is urge that overall education environment need to be improved to achieve its goal of the program. Second, the interview on the development direction is categorized as need, development direction, teaching method, evaluation method, activity, problem, improvement, solution, and etc. and, Third, the contents of the program include environmentally friendly elements such as wind, sun, mountain, river, sand, tree, flower, field to induce children’s interest and whole-person education. The contents of the program are expected to deliver hands-on experience for children. And also, the program includes physical activity using a nature object. Based on the potential problems we identified, a next study is expected to deal with following points. First, more empirical research is needed to prove the effectiveness of the program in a broad way by proposing a program that can be applicable at child-education center. Second, the study developed contents to make children feel enjoyable about nature. Unfortunately, in-depth research and development of such program is not sufficient. In this respect, more continuous research on Natural Physical Activity Program is required and need to be widely established.

In this study, we evaluated genotoxicity of heavy metals among particulates with Tradescantia-micronucleus (Trad - MCN) assay in the various working environment. In a synthetic fiber factory and a rubber factory, chromium concentration was higher than any other heavy metals. On the other hand, nickel concentration was the highest in a semi-conductor factory. The difference in genotoxicity among the working environment was statistically significant as Trad-MCN frequencies were 4.67±0.35 MCN/100 tetrads (p<0.01) for the synthetic fiber factory, 5.73±0.81 MCN/100 tetrads (p<0.0I) for the rubber factory, and 15.60±2.58 (p< 0.01) (p< 0.001) for the semi-conductor factory. As a result, heavy metals among particulates in the working environment can be considered to have hazardous potential to human health, although they cannot directly induce DNA damage to the workers in the working environments.
