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.

尹喜重 韓國體育大學校 1982 論文集 Vol.4 No.-

Physical education, through a great variety of activities, helps man develop efficient motor skills, physical fitness, a positive self-image, and socially desirable behavior. This study was under-ground, school curriculum, types of physical activities and hobbies. The individual sports and Busan areas were selected for sampling. Most of the players fail to have anopportunity to acquire knowledge and attitudes necessary for succesful participation in the future social life because emotional, cultural and home education is usually neglected. They need lots of activities that include the appropriate ways of body weight and condition control, which will provide them an emotional stability. Such offerings are greatly important for the proficiency in activities of their own specialization in their schools and particuar events.

Physical education, through a great variety of activities, helps man develop efficient motor skills, physical fitness, a positive self-image, and socially desirable behavior. This study was undertaken to discuss the consciousness of individual sport players in terms of their family background, school curriculum, types of physical activities and hobbies. Most of the players fail to have an opportunity to acquire knowledge and attitudes necessary for succesful participation in the future social life because emotional, cultural and home education is usually neglected. They need lots of activities that include the appropriate ways of body weight and condition control, which will provide them an emotional stability. Such offerings are greatly important for the proficiency in activities of their own specialization in Korean National College of Physical Education.

해양경찰조직의 진화론적 접근 : 해양경찰청(2003-2012)을 중심으로

윤희중 한국해양경찰학회 2014 한국해양경찰학회보 Vol.4 No.1

신제도주의적 관점은 관료제 변화를 제도의 역동성과 역사적 맥락에서 분석하는 것이고, 이 패러다임에서 파생된 역사적 제도주의는 제도의 변화를 역사적 산물로 설명한다. 특히 경로의존성은 과거 사건이 미래를 제약하여 제도의 지속성을 강조하 는 자기강화 과정에 대한 개념이고, 이 과정에서 관료제는 단계적으로 진화한다. 이 연구는 경찰 관료제의 제도적 진화를 논의하기 위한 노력의 일환이다. 이 연구 에서는 육상경찰의 진화과정 연구에 대한 후속 작업으로 해양경찰 조직의 진화과정 을 분석하였고, 2003년-2012년에 걸쳐 해양경찰청과 육상경찰을 비교·검토하였다. 약 10년에 걸쳐 해양경찰 조직은 형성기와 전환기 단계의 복합적 특징을 나타내 는데, 노무현 정부와 이명박 정부의 진화과정 특성을 살펴보면 다음과 같다. 정권교 체와 독도문제는 해양경찰의 조직이나 인력변화를 촉발시키는 계기가 되었다. 노무 현 정부에서는 본청의 참모기관을 활용한 반면에 이명박 정부에서는 본청이나 특별 지방기관의 집행기관 역할을 중요시했다. 해양경찰 총 정원은 노무현 정부에서는 증 가했지만, 이명박 정부에서는 감소했다. 한편, 노무현 정부와 이명박 정부에서는 대체적으로 계선기관보다 참모기관을 더 다양하게 활용하였다. 그리고 핵심인력인 경찰공무원의 수도 두 정부에서 지속적으 로 증가하는 추세이어서 정권변동에 크게 영향을 받지 않았는데 이러한 경향은 노무 현 정부와 이명박 정부의 육상경찰 추이와 비슷하다.

CW laser annealing 중의 실리콘의 순간 온도 측정

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.

투사각θ로 던진 투사체의 3차원 Mathematica Simulation

윤희중,박종엽 목원대학교 자연과학연구소 2001 自然科學 硏究論文集 Vol.10 No.2

이 논문에서는 Mathematica 4.1을 사용해서 투사각θ로 던진 투사체의 3차원 운동을 simulation하였다. 포사체 운동은 물리학의 기본이 되는 운동으로 물리학에 대한 기본적인 지식이 있는 사람이면 쉽게 이해할 수 있으나 Mathematica를 이용하여 프로그램을 작성하여 simulation해보면 포사체 운동을 좀 더 확실하게 이해 할 수 있다. 이 논문에서는 Mathematica를 간략하게 소개하고 Mathematica에서 포사체 운동을 simulation하여 대학 물리교육 현장에 적용한 과정을 제시하였다. Three demensional Mathematica simulation of the projectile with evaluation angle θ is presented. With this simulation, students can understand the motion of projectile more easily. We show interactive learning programs as examples to illustrate the concepts of projectile motion. We found that integrating the interactive Mathematica programs into physics class was very effective for improving the teaching and learning of physics in the undergraduate curriculum and for enhancing the ingenuity of students.

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.

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.
