The present study aims to investigate the styles of traditional classrooms and to discover the acoustic characteristics of the classroom. Acoustic experiments were undertaken at the Myoung Ryun Dang at the Cheongju Hyang-gyo which have typical style of the traditional classroom of Korea. The background noise level is about 37.3dB that is unsuitable for educational spaces. It is because lots of noise is coming from the outside. Several acoustic parameters were measured at 12 points including sound pressure level (SPL), reverberation time(RT), definition(D50) and speech intelligibility(RASTⅠ). It was found that SPL is reducing rapidly in proportion with the distance away from the sound source. The average value of RT is 0.75 second when classroom was empty which means the appropriate condition for speech. The average D50 value is a 0.60 that is regarded as suitable condition. The average RASTⅠ is 0.66 which is a value of satisfactory level. The result shows that Myoung Ryun Dang has good acoustic conditions with short reverberation time and high clarity in spite of the noises.

성명희 범태평양응용언어학회 1999 범태평양응용언어학회지 Vol.3 No.1

The purpose of this study is to investigate what beliefs Korean college students majoring in tourism English hold about learning foreign languages, particularly on English and to suggest the desirable directions of English teaching for them. To achieve this, one hundred and fourteen students at Seoul Health College participated in the study. A 30 item questionnaire(15 open-ended and 15 closed) about subjects` beliefs on language learning was grouped together into three categories. They included (1) beliefs on the nature of foreign language learning, (2) beliefs on the learners` own English learning, (3) beliefs on the learners' own language learning environment. The main findings and suggestions are provided.

Tourism English Teaching Techniques Converged from Two Different Angles

성명희 범태평양응용언어학회 2001 범태평양응용언어학회지 Vol.5 No.1

This paper aims to provide some techniques converged from two different angles(learners and tourism English features)for effective tourism English teaching in junior college in Korea. For this, comprehensive methods were undertaken: a questionnaire for learners` needs analysis, an instrument designed by Xiao-hua and Naerssen (1987) for learners` strategies for oral communication, a small-scale classroom study for learners`preference of teaching techniques; interviews for the feature of tourism English teaching. It is suggested that the specific knowledge of the content and the basic expressions of the content be first identified, and then, interaction, an essential factor, be focised on provoking learners` stategies for communication, and be placed on a continuum from predictable interaction to language parctice, along with various groupings, supports of grammar knowledge when necessary.

데이타 플로우 시스템의 화일 처리에서의 병렬효과

성낙운,김명순 경성대학교 1989 論文集 Vol.10 No.1

In order to realize very high performance computers, many people demand a new computer system, It is called to be the data flow computer that is no concept of global updatable memory and memory counter different from conventional Von Neumann type computers in structure. To provide storage for large volume of information and allow sharing of information files must be used in the data flow system. A file is regarded as stream stored in the external device separated from the data flow file system and data flow fill system provides an interface to the data flow system. To enhance file concurrency, new data flow window concepts are proposed, it is provided to reduce the data movement overheads between the data flow system and the external environment. Macro and overlapped windows are also used to reduce oveheads when external files are accessed from the data flow system.

This study was peerformed the effects of balance taping on the changes of heart rate and blood lactate concentration during longterm submaximal exercise. The results were as follow:Heart rate and blood lactate concentration of taping group at 40 mins and 50 mins during exercise showed a significant(P < 0.05) lower values than control group. At the immedately and recovery 15 min after exercise, heart and blood lactate concentration of taping group showed a significant(P < 0.05) lower values as compared to control group. In the recovery rate of heart rate and blood lactate concentration, taping group showed a significant(P < 0.05) higher values as compared to control group. In this results, the taping was suggested the effective method for acute recovery of exercise-induced fatigue.

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with florisil, and finally analyzed simultaneously the organochlorine and pyrethroid pesticides using GC(ECD). An ultra-2 fused silica capillary column was used to separate and identify the products. The resolution between the last isomeric peak of cypermethrin(59.987min) and the first isomeric peak of flucythrinate(60.043min) was not satisfactory. The last isomeric peak of fenvalerate(62.344min) and the first isomeric peak of fluvalinate(62.397min) were overlapped. Recoveries of soybean sample for the most pesticides were 73.3% to 102.4%. Detection limits were between 0.004 and 0.063 ㎍/㎎ when this method was used.

원격영상강의에서 발생하는 상호작용의 빈도와 유형이 학습 동기유발에 미치는 영향

강명희,김서영 한국교육정보방송학회 1996 교육정보미디어연구 Vol.1 No.2

본 연구에서는 원격영상 강의를 시범적으로 실시하고 있는 '한국방송대학교'의 2개 강좌-사회과학 계열 1개 과목과 인문과학 계열 1개 과목-를 모국과 자국 모두 관찰함으로써 원격교육에서 상호작용이 어떠한 빈도와 형태로 나타나고 있으며 이는 학습자의 동기유발에 어떠한 영향을 미치는가를 조사하였다. Flanders의 상호작용 분석법을 활용하여 비디오로 촬영한 강좌 상황을 분석한 결과는 다음과 같다. (1) 사회과학 계열의 과목이 인문과학 계열 과목보다 교사 대 학습자 (T-S), 학습자 대 교사(S-T), 학습자 대 학습자(S-S) 상호작용이 많이 일어난 것으로 관찰되었다. (2) 모국과 자국의 비교에서는 모국이 자국에 비해 일반적으로 상호작용이 많이 일어나며, 그 유형은 교사 대 학습자(T-S) 상호작용이 주를 이루었다. (3) 상호작용이 많은 것이 학습자의 동기를 전반적으로는 유발하지 않았으나. T-S 유형은 학습자 의 주의력에 S-T 유형은 학습자의 자신감에 의미있는 영향을 주는 것으로 나타났다. The purpose of the study is to investigate the frequencies and patterns of teacher-student interaction and gain insight on the student motivation regarding interaction through two video conferencing courses being implemented at Korea Open University during the fall semester of 1995. The results revealed the lecture K provided much more interaction than lecture M. In lecture K, teacher-student interaction was prevalent. On the other hand, student-teacher interaction was more observed in lecture M. The on-site location showed more interaction than remote-site in both lecture. On-site location, teacher-student interaction was more frequently observed and student-teacher interaction was shown more in remote-site. Analysis of the relationship between interaction pattern and student motivation revealed that there was no correlation between interaction pattern and student motivation. All pattern of interaction could not be directly correlated to overall students motivations. However, it was elucidated that the Teacher-Student pattern enhanced attention of the students and the Student-Teacher pattern positively influenced confidence of the students.

최명수,박남철,박형준,김경호,이성로 목포대학교 정보산업연구소 2000 情報産業硏究誌 Vol.8 No.-

The use of the Internet is much increased and the multimedia data such as voice and image should be processed in the Internet. The required characteristics of the communication networks for the 21-st century Internet are the fusion between communications and broadcasting, high speed, large capacity, high intelligence, and personalization. In realizing the characteristics mentioned above, the ATM is the only technique that can practically guarantee QoS and is the core technique in super high-speed service networks. In this paper, we will investigate the international study of the high-speed the satellite communication and then research plans for developing and providing optimum application services.
