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.

Pineal germinoma is one of the most radiosensitive intracranial tumors and so recently a regime of radiotherapy combined with ventricular shunting was advocated. But not infrequently seeding through the subarachnoid space and shunting system was observed. We have experienced a pineal tumor, which was treated completely by irradiation following ventriculo-atrial shunt but without evidence of intracranial recurrence spinal metastasis occurred 16 months later. After myelography total laminectomy from L1 to L3 was performed and intradural tumor was removed. Histopathological diagnosis was germinoma. After wonud healing spinal axis irradiation was performed with symptomatic improvement.

第三共和國의 政府 PR의 現況

尹嬉重 이화여자대학교 한국문화연구원 1971 韓國文化硏究院 論叢 Vol.17 No.-

Public relations is a vital tool of adjustment, interpretation, and integration between individuals, groups, and society. Today public understanding and support is basic to existence in our competitive system, and the writer believes that maladjustment in the field if government is based on the misunderstanding of realities and communication processes. The three main elements of public relations are practically as old as society itself: informing people, persuading people, and integrating people with people. However, the means and methods of accomplishing these ends have greatly changed as society has changed. At the same time, the constant and recognizable goal pf public relations activities-good will-is always presents. Public relations as an activity over the year are a response to the problems facing an institution. Administrations need to explain governmental operations and activities to citizens who were affected by them. The work of the departments and agencies on all governmental levels must be interpreted. Administrators need to find out what citizens consider the shortcomings of the agencies and what methods might be used to improve them. This is the practical, two-way function of public relations applied to government. This thesis seeks to give a broad, over-all view of government public relations in Korea, excluding the area of external (foreign) public relations. The problem of writing a thesis on ROK government PR was immense since the securing of the necessary facts and data in statistically usable form was almost impossible. The thesis consists of six parts. The first part is introductory. Its purpose is to explain why this sort of work should be undertaken. There is no easy approach or solution when dealing with government public relations in contemporary society. The second part is devoted to democracy and public information. The study of public relations activities of the government eventually leads to the problem of what is essentially required for the modernization and democratization of our country. Information is essential to a democratic society. Public relations provides the knowledge and the techniques that enable leaders to be more effective. In a democracy, leadership is dependent in understanding the public and knowing how to reach it. The citizens have a right to know what these agencies and departments of their government are doing. Democracy depends on a well-informed citizenry if government is to function successfully. The third part is dedicated to presenting a clear picture of the past and present of the ROK government public relations. Also, this part handles the comparative study of political systems, and the organization of the public information department, past and present. To provide the background for a better understanding of government public relations today, this part begins with a survey of the development of a public information system from 1945 to the present time, showing how the exigencies of modern life have created a demand for specialists in public relations. The difference between the First Republic (Liberal Days) and the Second Republic(Democratic Days) represents two extremes: the Liberals can be characterized by their authoritarianism and the Democrats by their liberalism. The Third Republic may be characterized by its extensive use of mass communication media for the purpose of government public relations. The fourth part deals with realities of the Third Republics government public relations. This part handles the analysis of public information administration of the ROK: policies, organizations, budgets, personnel and media. Important to an understanding of government public relations is a knowledge of how and why it developed as an activity. As the impact and extent of government increases, the need for adequate communication between public officials and citizens becomes more urgent. The fifth part is an attempt to analyze the mass communication media used for the government public relations after the May revolution. The writer seeks to discuss the various tools of public relations used. While many think that government information work consists exclusively of news releases to commercial news media, the government agencies are compelled to use a variety of media to reach their general and specialized publics. External periodicals, informational brochures, motion picture films, filmstrips, slides, etc. are needed to carry the agencies' messages. The government information men use speakers and exhibits for national fairs to give the publics the facts about the services of their agencies and to educate them about community, industrial, or other problems with which the government agencies deal. In this section the study is divided into three major parts: the publishing field, the broadcasting field, and the field of motive, exhibition, special event and research. Finally, in the sixth part, the thesis concludes with a presentation of the improvement of government public relations here in Korea, indicating some obstacles to the effective operation of the government public relations policy. Significant factor to be considered for the future fruitful implementation of the government public relations programs, besides organization, budget and manpower, is the scientific formulation of systematic and continuous policies. As a result of this study the writer has become convinced that the existing public relations activities to of the government require many changes or modifications in the future. One such modification is that the strengthening of public opinion surveys and other research tools is necessary to obtain the information required for future public information activities. The writer hopes that this kind of study will make a useful contribution to the foundation of constructive policy formation in a modern public relations system in Korea, while at the same time benefiting and stimulating students to further research in this influential field. Interspersed throughout the thesis are 14 charts and graphs which present trends in government public relations activities and expenditures over the period 1945-1970.

民主社會와 公報 宣傳 活動

尹嬉重 이화여자대학교 한국문화연구원 1974 韓國文化硏究院 論叢 Vol.23 No.-

Since democracy depends on a well-informed citizenry, if government is to function successfully, the free flow of information to the public is vital to the health of modern democracy. In reality, a democratic state is under constant temptation to borrow tactics and techniques, as far as the manipulation of public opinion is concerned, which have proved successful for a totalitarian state. Thus the problem of government domination of public opinion remains a serious one even in a democratic state. Through the skillful use of mass communication channels along with the suppression of information flow, the rulers in a democratic state can easily shape the contours of majority opinion. And one must admit that the capacity to manipulate domestic opinion can be an invaluable asset to any government involved in international conflict. This thesis seeks to give an over-all view of the relationship between a democratic society and a public information service provided by the government. At the same time it will indicate some obstacles, hostilities, and limitations to the effective operation of a public information service. This paper consists of six parts. The aim for the first part is to explain why this kind of study should be undertaken. The second part is devoted to politics and communication in a democratic country and will also consider some of the interrelationships between the two. The third part deals with publics opinion and government propaganda and the ways in which they are interrelated. The fourth part is an attempt to discuss in general terms the antagonism and limitations of government public relations which can arise from the theory of marginal utility. The fifth part deals mainly with the United States government public relations program. Important to the understanding of government public relations in a democratic state is a knowledge of how and why this kind of a program has developed. Since many governments model their public relations programs after the United States, a look at this activity as it is practiced in reality is of great value. Finally, the thesis concludes with a presentation of a way to improve government public relations in general, indicating limitations of and obstacles to the effective operation of a government public relations policy in a democratic state.

윤희중,문동안 한국운동역학회 1999 한국운동역학회지 Vol.9 No.1

This study is to investigate the biomechanical factors during the Depth jump. Subjects for this study were 12males, they were grouped in 2guoup by age(20s, 40s). All the subjects were required to perform Depth jump in 3 directions(front, backward, vertical). The performances of all the videotaped(60Hz). The recorded images were subject to digitizing with KWON3D Motion Analysis Package. while the ground reaction force were collected with KwonGRF ground Reaction Force Analysis Package. After collecting the data, the selected kinematical and kinetical variables were computed in relation to jump direction and age. Based on the results of data, the following conclusions were drawn; 1. Differences of jump direction and age have an effect on the jump height and stance time. 2. Differences of jump direction have an effect on the ground reaction force, while age differences have not effect on the ground reaction force. 3. Differences of jump direction have an effect on the hip and ankle angles but have not an effect on the knee angle. Differences of age have an effect on the the hip, knee and ankle angle.

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.

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.
