Mathematica를 이용한 대학 물리교육의 새로운 학습도구 개발

윤희중 목원대학교 자연과학연구소 2001 自然科學 硏究論文集 Vol.10 No.1

Mathematica를 이용하여 추상적이고 난해한 물리학의 개념들을 가시화하고 강의 현장에서 insitu로 확인할 수 있는 학습도구(courseware)를 개발하였다. 물리학과의 학부 과정에서 강의만으로는 이해하거나 실험실에서 직접적으로 실험해 보기 곤란한 물리현상들을 결정하고 이들을 학습현장에 적용할 수 있는 프로그램을 제작하였다. 본 논문에서는 양자역학의 energy eigenvalue를 계산하고 그래프를 구하는 문제를 Mathematica 4.0에서 작성하고 교수학습 현장에 적용하는 과정을 제시하였다. Mathematica를 교수학습현장에 도입함으로서 좀 더 역동적인 교수학습이 이루어지고 물리학도들이 쉽게 컴퓨터 프로그램 기법을 익히는 데에 도움이 되어 지식정보화 시대의 새로운 courseware가 될 수 있음을 확인하였다. A Mathematica courseware illustrating the complicated physics concepts of the angular momentum problems in quantum mechanics is presented. We have shown the calculation and visualization of the energy level of a rigid rotator having a Hamiltonian aL_x^2+bL_y^2+L_z^2. We found that it is very useful to integrate Mathematica into physics class of improving the teaching and learning of physics in the undergraduate curriculum and to enhance the computer programming skills for students.

The study was to investigate the limitation of bodyweight reduction in each boxers. The subjects who belong to college caliber elite boxer were measured physiques, physical fitness factors, and treadmill test in normal condition and drug progressive bodyweight reduction. The results which is based on individual data were summarized as follows: 1. In case of subject K.J.S, some of muscular strength factors were decreased with 4 Kilogram bodyweight reduction, but others were sustained normal condition with 5 Kilogram bodyweight reduction. Base on this results, it could be concluded that subject K.J.S.would be sustained normal condition, despite bodyweight was reduced by 5 Kilogram. 2. In case of subject P.K.S., muscular strength, power, agility and cardiopulmonary function were decreased significantly with 4 Kilogram bodyweight reduction. Base on this results, it could be conclude that subject P.K.S wouldn't be sustained normal condition over 3 Kilogram bodyweight reduction. 3. In case of subject J.J.H., there were no significant decreasing in most of tested items, despite the weight was reduced by 5 Kilogram. Based on this results, it could be concluded that subject J.J.H would be sustained normal condition by 5 Kilogram bodyweight reduction. 4. In case of subject S.K.S., muscular strength and cardiopulmonary function were decreased with 4 Kilogram bodyweight reduction. base on this results, it could be concluded that subjects S.K.S. wouldn't be sustained normal condition over 3 Kilogram bodyweight reduction. 5. In case of subject K.S.G., muscular strngth, agility, power, and cardiopulmonary function were even increased after 4 Kilogram bodyweight reduction. Based on this results, it could be concluded that subject K.S.G. would be sustained super-normal condition, despite the weight was reduced by 4 Kilograms. 6. In case of subject L.S.R., power, flexibility, agility and mumuscular strength factors except backmuscule strength were increased. with 4 kilogram bodyweight reduction, but cardiopulmonary endurence was decreased over 3 Kilogram bodyweight reduction. Base on this results, it could be concluded that subject L.S.R. would be sustained normal condition, despite the weight was reduced by 4 Kilogram. 7. In case of subject C.H.G., muscular endurance, flexibility, aagility, muscular sterngth factors except backmuscle strength were increased, but power and cardiopulmonary function were decreased with 4 Kilogram bodyweight reduction respectively. Based on this results, if could be concluded that subject C.H.G. would be sustained normal condition, despite the weight was reduced by 4 Kilograms. 8. In case of subject C.B.H., muscular sterngth, power and agility were increased, and muscular endurance, flexibility were decreased with 4 Kilogram bodyweight reduction respectively.

윤희중 牧園大學校 1987 論文集 - 牧園大學校 Vol.12 No.-

Time-resolved Si I attice-temperature measurement has been developed during cw laser annealing by utilizing the time-dependent optical interference in Si on sapphire(SOS). This interference is due to change in Si lattice-temperature. A new method using a microscope is demonstrated for time-resolved Si lattice-temporature measurement during laser annealing.

한국 텔레비전 방송과 어린이에 대한 연구 : 특히 TV매체의 cultivation effects를 중심으로

윤희중 이화여자대학교 한국문화연구원 1988 韓國文化硏究院 論叢 Vol.53 No.-

Korea, along with its extraordinary economical growth, has seen a matching growth in the media industry and media consumption. The expeditious development of mass media, a characteristic of industrialization, disseminates a standardized, typified, homogenized culture through the mechanisms of mass communication. Television, because of its wide diffusion, plays a central role in the creation, dissemination and maintenance of the culture of a particular society. Public and commercial television broadcasting systems presently coexist in Korea. This combined structure was initially aimed at the realization of the public interest and the cultivation of a healthier popular culture. But because of the capitalistic properties of the television media, television is presently more inclined to the degradation of popular culture rather than its upgradation. This research interests itself with the influence of popular culture on the thought processes and living patterns of its consumers, (3rd and 6th grade children). It concerns itself specifically with what is being transmitted by television and how this is being received and processed by the audience of 3rd and 6th grade children. A combined method of content analysis of TV programs and audience survey was used for this study. An audience survey was carried out to compensate the impracticality of earlier studies which only analyzed the contents of TV programs and deduced the effects unilaterally and theoretically. The survey essayed to discover how the contents of television was actually accommodated and evaluated by the audience. Content analysis of TV programs were carried out for a period of one week from Feb. 2(Mon.), 1987 to Feb. 8(Sun.), 1987. Two or three broadcasts were selected on an alternative day basis for daily programs (in the case of a fifteen minute program), one broadcast for weekly or semiweekly programs and three broadcasts per station on an alternative day basis for daily news programs were selected for analysis. Quantitative analytical methods were mainly used but content properties which could not be quantified were examined through qualitative methods. The criteria and unit of analysis was varied for different programs in accordance with each program's peculiarity. The audience survey was carried out in the Seoul area through a pre-structured questionnaire. The results and problems raised through content analysis show that although TV does not affect children's consciousness and behavior pattern absolutely, however analysis pointed out following problems in programs for children in Korea TV broadcasting. 1) Violence becomes main means of solving problem in cartoon and it created a sense of value to children that violence is more easy and fast way than dialogue and compromise in solving problems, 2) Distinct comparison of characters between good and bad man, male and female appeared on the stage will put narrow-minded sense of value such as black and white logics to children. 3) Behavior and means of the star in drama brings often to good result even if behavior and means are wrong and this kind of notion will put into mind of most children than it can be justifiable to rationalize their object even if behavior and means are wrong. 4) Education program was made up mostly for entertainers and much of amusement, and children only take part of program very passively. 5) Bad slang and meaningless foreign words are often used in program and it makes children imitate wrong words, custom and behavior. Writing on the limitations of this study, one can see the period of content analysis and the period of the audience survey were almost 6 months apart. There was also a rescheduling of program during this period. These facts, along with the political changes that occurred during that period would be the limitations to this study. But these limitations probably were not that decisive considering the fact that the contents of television programs were relatively unchanged and that the questionnaire strived for an evaluation of the audience responses rather than a causal explanation.

Marketing channel system의 communication戰略

尹嬉重 이화여자대학교 한국문화연구원 1980 韓國文化硏究院 論叢 Vol.35 No.-

Today, marketing channels are among the most complicated phenomena encountered in the study of marketing since marketing channels encompass behavioral systems involving many decision markers and often extend over a wide geographical area. For this reason, as integrated systems approach is inevitable to the overall understanding in the structure and functions of communication in modern marking channels. This thesis utilizes an integrated systems approach as the analytical framework for studying and understanding communication in marketing channels. Generally, communication strategy occupies a pivotal position in the overall marketing mix of the firm. The ingredients that make the marketing alive, effective and dynamic lie in the realm of communication. However, it is important to point out here that the types of information flow in marketing channel systems that are of primary importance closely parallel the functions of marketing. It is the role of communication to inform and persuade the potential consumer that other elements of the marketing mix-product, price and physical distribution are worthy of consideration in purchasing decisions. Therefore, the planning of communication strategy in marketing channels necessarily takes place within the development of basic marketing goals objectives by top management. The thesis consists of six chapters. The first chapter is introductory. Its purpose is to explain the reasons that this sort of work should be undertaken. The second chapter provides both the conceptual foundation of marketing and a descriptive overview of marketing from a historical developmental approach. The third chapter develops the concept of the channel as an operating systems and analyses specific structure of channel systems. While introducing the meaning of marking channels here, the rationale for the systems approach to marketing channels is also examined. The fourth chapter describes the selection and control of communication in marketing channels. This chapter also examines the reasons for conflict and their resolution within the marketing channel system. The fifth chapter points out that the internal and external information flows within channel links are necessary for effective operations and that persuasive communication among channel links is necessary in order to gain response from either a channel member or the ultimate consumer. Chapter five also analyses both the role of research as communication feedback in the channel process and the decision strategy to be employed in the actual design of the channel network. The sixth chapter concludes with an analysis that may influence the role of channel members and finally presents here the methods to improve or develop effective communication strategies in marketing channel systems today.

윤희중,강관희,김태삼 한국체육대학교 체육과학연구소 2000 韓國體育大學校附屬 體育科學硏究所論文集 Vol.19 No.1

This study is to analyze the kinematic variables of forehand and back- hand volley in tennis. Five male tennis players are used as subjects, two S-VHS video cameras set in 60frames/sec were used for recording volley motion. Coordinated raw position data through digitizing are smoothing by low-pass Butterworth filtering method at a cut off frequency 6Hz, and the direct linear transformation(DLT) method was employed to obtain 3-D position coordinates. The conclusions were as follows; 1.In the swing time, forehand volley was longer than backhand volley in phase1, but forehand volley was shorter than backhand volley in phase2, forehand volley was shorter than backhand volley in the total swing time. 2.Backhand volley was longer than forehand volley in displacement of Y axis direction and the height of CG was similar to the forehand and backhand volley in total swing phase. 3.At the point of impact, the resultant velocity of racket head was similar to the forehand and backhand volley, and the maximal resultant velocity of racket head occurred before impact. 4.In the angle of the frontal trunk, the wrist and the knee, forehand volley was larger than backhand volley in each event, and each segment angle increased before impact to except the wrist angle of backhand volley. 5.In the angular velocity of the wrist, forehand volley was positive addition and backhand volley was negative addition at impact.
