Lately, Koreans are drastically getting more interested in sports to improve their health as the quality of their life is improving. Following this trend, government agencies and local organizations have been continuously building community sport facilities near residential areas. These facilities are required to be equipped with a good level of acoustic performance for music and speech delivery: communication and / or music between sports-players while games, leisure sports, and training are carried out. However, excessive reverberation occurs at most of old community sports facilities built with lightweight panels as finishing materials so the facilities users have been continuously complained about this. With respect to this, the research has attempted to suggest the optimum acoustic performance of six community sports facilities that lightweight panels were used for finishing materials. After acoustic performance surveys of these facilities were carried out and found out the problems using acoustic simulations. The results of the surveys revealed that excessive reverberation occurred at the facilities with lightweight panels and this caused difficulties of communication. Acoustic performance of the community sports facilities was evaluated to be suitable after adjustments of the room constant according to their appropriate Reverberation Time (RT). This result is thought be useful for design and refurbishment of similar community sport facilities in the future.

Lately, owing to development of modern society, as living quality of people has been enhanced, interests in health improvement are being increased drastically. In accordance with these, our nation and local governments are building social physical facilities for local community residents consecutively. These most social physical facilities need sound clarity for smooth communications among athletes in playing games and simultaneously music clarity for music in rest and performances. But, in case of most social physical facilities which were established previously, due to the reasons of simplicity and economic feasibility of construction, as the facilities were finished with lightweight panels, lots of faults are being shown presently. Therefore, after physical acoustic performance was analyzed by conducting field measurement aiming at social physical facilities that were finished with lightweight panels, and based on it, this study tried to grasp acoustic problems.

Large gymnasia are utilized for multi-purpose events such as sports, performance, and a range of events. However, old gymnasia show many acoustic defects and in order to correct them, changes of finishing materials and partial interior-design are employed for improvements of their acoustic performance. Nonetheless, some research are required to be carried out because subjective responses actually experienced by audiences might not be improved after these changes. With respect to this, the research has attempted to look into differences of the subjective responses between before and after acoustic performance improvements made at five old large gymnasia. In the cases of a gymnasium where the Reverberant Time (RT) has been shortened, the reverberant, the loudness, and the diffusion have been decreased but the definition, the clarity, the intimacy, the balance, and the warmth have been increased. In the cases of a gymnasium where the RT has been lengthened, the subjective responsese has shown the opposite result to the case of the RT shortened except for the warmth. Therefore, subjective responses illustrate positive reactions after improvements of acoustic performance have been made as adjusting changes of finishing materials, sound absorbing power, and room constance. This result is thought be useful for design and refurbishment of large gymnasia in the future.

이 연구의 목적은 보다 효과적인 수업을 계획하기 위하여 중등 체육교사의 교수 계획 준비도에 대한 인식과 교수활동을 수행할 때 주된 초점이 무엇이고, 미비한 부분이 무엇인가를 밝히는데 있다. 따라서 체육교사의 수업 계획준비 실태 및 개인적 특성에 따른 교수 계획 준비도의 차이를 규명하는데 있다. 이를 위해서 연수를 받는 중·고등학교 체육교사 230명을 대상으로 편의 추출법을 사용하여 표본을 추출하였다. 조사도구는 설문지며, 탐색적 요인분석을 통해서 교수 계획 준비도의 하위 변인을 5개 변인으로 구성하였다(수업조직 계획준비, 수업운영 계획준비, 학생평가 계획준비, 피드백 계획준비, 학습관리 계획준비). 수집한 자료는 SPSSWIN Ver 8.0을 이용하여 기술통계분석(Descriptive analysis)과 일원변량분석(one way ANOVA)을 실시하여 다음과 같은 결론을 얻었다. 첫째, 체육교사의 교수 계획 준비도의 인식정도는 평균보다 비교적 높게 인식하고 있는 것으로 나타났다. 그 중 수업운영 계획준비와 학습관리 계획준비는 상당히 긍정적으로 높게 인식하고 있는 반면, 피드백 계획준비는 교수 계획 준비도 요인 중 가장 낮게 인식하고 있었다. 둘째, 체육교사의 경력에 따른 교수 계획 준비도는 수업조직 계획준비, 수업운영 계획준비, 학습관리 계획 준비 요인에서 통계적으로 유의한 차이가 나타났다. 그리고 근무교에 따라서는 학생평가 계획준비 요인에서만 유의한 차이가 나타났으며, 수업시수에 따라서는 수업조직 계획준비, 학습관리 계획준비 요인에서 통계적으로 유의한 차이가 나타났다. 이처럼 체육교사의 개인적 특성에 따라 4개 변인에서는 부분적으로 유의한 차이가 나타났지만, 피드백 계획준비 요인에서는 유의한 차이가 나타나지 않았다. The purpose of present study is to ascertain the awareness on the preparation level, main focus during teaching, and weak point for effective teaching in physical education of middle school setting. In addition, the difference of the degrees of class preparation would also be examined according to the real condition of teaching preparation plan(TPP) and each teacher`s personality. For the purpose, 230 teachers were randomly sampled who charge in physical education in middle and high schools and participate in training course. A questionnaire was used as research tool, and five variables were made for the TPP after an analysis on exploratory elements: plans of class organization, classroom management, evaluation, feedback and discipline management. SPSSWIN Ver 8.0 was used for the collected data on which descriptive analysis and one-way ANOVA were applied. The results are as follows: First, degree of awareness on TPP of physical education teachers was rather higher than average. While they were aware of plans of classroom management and discipline management with considerable positiveness, their awareness of the plan of feedback preparation was least among the variables. Second, four elements showed a significant difference statistically: the preparation plans for class organization, classroom management and discipline management showed a significant difference according to teacher`s individual career experience; as for the age of teacher, the preparation plans of class organization and discipline management showed a significant difference; as for the type of school, only the plan of evaluation showed a significant difference; and the plans of class organization and discipline management showed a significant difference according to teaching hours per week. On the contrary, there was no statistically significant difference for the plan of feedback.

Machine room Packed with various machinery are one of the greatest sources of noise. Noise made by a machine room is transmitted to residential spaces as air-borne sound as well as. disturbing residents' pleasant living environment and causing public complaints. In addition. many buildings that were constructed without full consideration of soundproofing in design issues need to be repaired to control noise at high costs. Therefore. the purpose of this study is to provide basic information for establishing consideration against noise from machine rooms. by measuring and analyzing noise made by machinery in the machine room of dormitories at J. W and H University which had different characteristics.
