The differential cross sections for the process W+P→γ+ hadrons in the Quantum chromody-amics and in the Unified gauge theory have been calculated. These calculations have been carried out in the parton picture with impulse approximations. The quark contributions to the differential cross sections show that the predictions from the broken color gauge theory are about 1.5 times larger than those from the quantum chromodynamics.

대학물리실험 교육 개선 방안

이철세 培材大學校 1997 培材論叢 Vol.2 No.-

대학의 물리 실험은 학생들의 탐구 능력과 과학적 사고력을 높이며 창의성을 개발할 수 있는 방향으로 진행되어야 하며 흥미를 유발할 수 있는 다양한 방법이 제시되어야 한다. 그러나 현재 대부분의 대학에서 수행되는 물리 실험은 고등학교의 실험과 중복되는 과제가 많고 학생들의 행동 요소가 지나치게 구체적으로 명시되어 있으며 결과의 처리 방법 또한 지나치게 규격화 되어 있어서 학생들은 실험 교재에 명시된 지침 대로 기계적으로 행동하게 되는 경우가 많다. 따라서 실험을 통한 학생 주도의 탐구활동과 창의성 개발을 기대하기 어려운 상황이므로 이를 개선하기 위한 방안을 제시한다. These days almost students in university follow the standard process of experiment and there is no room to stand new idea and process. So a new method of experiment for college physics is proposed to provide the opportunities for the students who can plan all the process of experiment and apply new ideas.

The law of Bio-Savart shows that a moving charged particle makes magnetic field. But the movement of particle can not be measured at the same velosity moving coordinate, and the magnetic field can not be measured. To sove this paradox, we must accept the fact that the velosity of the moving charged particle relative to the opposite charged particle is the essential factor of the magnetic field.

Objectives: This study examined the relationship of fatigue to medical utilization, occupational accident and sickness absence. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project, 2002~2004). A total of 30,146 employees categorized within the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were recruited. A structured-questionnaire was used to assess the participants' sociodemo-graphics, job-related factors, health-related behaviors, personality trait, self=perceived fatigue (MFS) and the frequency of medical utilization, occupational accident and sickness absence. Data on medical utilization and occupational accident were confirmed from company health records. Chi-square test and logistic regression analysis were used to elucidate the relationship of self-perceived fatigue to medical utilization, occupational accident and sickness absence. Results: In logistic regression analyses, self-perceived fatigue was associated with medical utilization (outpatient), occupational accident and sickness absence although the strength of the associations was higher in the blue collar workers except for medical utilization. For medical utilization, the white collar worker's adjusted odds ratios of outpatient utilization for workers scoring in the third quartile and the highest quartile, compared to workers scoring in the lowest quartile were 1.50 (95% CI: 1.20-1.87) and 2.16 (95% CI: 1.69-2.75), respectively. The blue collar workers' adjusted odds ratios of outpatient utilization for workers scoring in the second (OR: 1.23, 95% CI: 1.06-1.43), third (OR: 1.42, 95% CI: 1.22-1.66) and highest quartile (OR:1.83, 95% CI: 1.55-2.17), respectively, compared to workers scoring in the lowest quartile were statistically significant. However, no associations were found between fatigue and inpatient utilization for either the white or blue collar workers. The blue collar workers' adjusted odds ratios of being injured for workers scoring in the second, third and highest quartile were 1.41 (95% CI: 1.00-2.00), 1.57 (95% CI: 1.10-2.22) and 2.41 (95% CI: 1.69-3.44), respectively, compared to those scoring in the lowest quartile, but, those of the white collar workers were not significant. There was more likely to an increased risk of sickness absence in workers scoring in the second, third and highest quartile compared to those scoring in the lowest quartile in both white and blue collar workers, but the magnitudes of risk were higher in the blue collar workers than the white collars workers. Conclusion: This result suggests that fatigue is a determinant predictor of medical utilization, occupational accident and sickness absence, and that the pattern of risks for the three outcomes differs according to the occupational type. Some limitations of this study and considerations for future study were also discussed.

The objective of this study is to analyze the stability of international wheat market and the impact of the Uruguay Round on international wheat market and major wheat trading countries. In order to achieve the objective of the study, standard error and coefficient of variation are estimated by country, region and different periods for the comparison of stability of wheat market. To draw prospects of international wheat market after the Uruguay Round negotiations, major wheat trading countries' country schedule and results of previous studies are reviewed. Major findings of the study are; (1) Stability of international wheat market has been increase and the result of the Uruguay round will contribute to enhance market stability. (2) exporters' behavior is more stable than importers' mainly because of export subsidy. (3) Implementation of the result of the Uruguay round will increase wheat price by 6% in international market and reduce quantity traded. (4) The U. S. will increase its market share while EU will lose.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

法律扶助의 理論과 實踐

Under the current legal system, Legal Aid is of the official counsel and the cost exemption in the Criminal Procedure Law and of the litigation assistance in the Civil Procedure Law. But in practice, official counsels are often appointed pending in the court and argue the case for the defendants like that "we want to deal with the accused to leniently." And also the cost exemption and litigation assistance are not put to practical use today. The legal aid system is necessary in not only a Criminal but also a Civil Procedures. It must be properly recognized in both ones. The meanings of those terms are not clearly applied because the history of the system is short. However the supports in the legal procedure like the counsellor designation and cost exemption are called as the Legal Assistance. This support outside the procedure, that is, the legal counsultance and legal guidance, is called as the Legal Advice. It is proper to regard the Legal Assistance and Advice as the Legal Aid. Having the Legal Aid been an institution aimed at to protect safeguard the socio-economically poor, it is understood and specified as a Sozialrecht in the western countries. We think our system must introduce the Legal Aid which are comprised in the people's right of life (Recht auf Existenz). Public defender in the America is an example. Since the Legal Aid is for the poor or misfortunate, it is based on the neighborhood spirit. Therefore the Legal Aid can be developed as jurist body's or each law school's new town movement. The practice of this Legal Aid shall be preceded by the education of lawers, and it must be attended with an improvement of the existing legal education.

Nine nano-sized Fe-Co particle samples synthesized by Chemical Vapor Condensation(CVC) were analyzed using Mo¨ssbauer spectroscopy, XRD, BET and HRTEM. The synthesized nanoparticles consisted of metallic core and oxide shell structures, and their surfaces were covered with a-FeOOH, γ-FeOOH and Fe_(3)O_(4). The increase of cobalt content enhanced magnetic field. However, when the decomposition temperature and the oxygen content in the carrier gas (Ar) increased, the magnetic field of nanoparticles reduced with decreasing the average particle size. with increasing the vacuum pressure, the average particle size and the magnetic field increased.
