대학생 스트레스 영향 요인에 대한 연구 : S대 경영계열 학생을 중심으로
권순일 신라대학교 경제경영연구소 2009 경제경영연구 Vol.10 No.1
Nowadays, Stress is becoming an increasingly important concern both in student and in university. This is because of the tremendous results which are caused by it. Thus, the objective of this study is to make some contribution to reduce the stress of students. To accomplish this objective, after reviewing many literature about stress, we clarified the concept of stress and suggested the necessity of stress management examining aversive effect of it. At the same time, in addition to exploring five models relating stressor to stress symptom, we also illustrate stressors on which were commonly emphasized by the previous works on stressors of university student. Based upon the theoretical background, we analyzed the influential factors of stress symptom outcome through the empirical research. The main findings out of the analysis are as follows; First, it was indicated that the correlation of each stress-factor with others are, in some degree, statistically significant by directly or indirectly. Second, the regression analysis, using stress-factors and intervenient factors as predictors, showed that all the stress-factors except 'low academic record' and 'no participation', and the social support factor had influenced the stress outcome, namely stress symptom. but in the case of the personal factors such as A-personality, gender, age, grade, there were no significant influence on stress symptom. Finally, the moderated effects of intervenient factors were investigated through the ANOVA. it was indicated that both the social support factor and the personal factors somewhat functioned as moderators of relating between stressors and stress symptom outcomes. but the buffer effect of the moderators were turned out to be found, only in 12 of 55case.

권순일,고성주,박인원 대한안과학회 2009 Korean Journal of Ophthalmology Vol.23 No.4
Purpose: To evaluate the clinical course of visual acuity and foveal thickness in the idiopathic epiretinal membrane (ERM) after a vitrectomy with the use of triamcinolone. Methods: We retrospectively reviewed the records of 30 patients (30 eyes) with ERM that were treated by vitrectomy from 2004 to 2008. Visual acuity and foveal thickness from optical coherence tomography imaging was obtained preoperatively and at every postoperative follow-up visit. Results: Visual acuity improved by two or more lines of vision in 30%, 50%, 60%, and 70%, and stayed the same within ±1 line in 47%, 50%, 40%, and 30% at one month, three months, five months, and seven months after surgery. Twenty-three percents of the subjects deteriorated by two or more lines of vision within one month after surgery. None of the subjects had reduced vision three months after surgery. Foveal thickness decreased significantly after surgery. The mean thickness was 409.7±107.9 ㎛ before surgery and 288.6±66.1 ㎛ seven months after surgery. Parameters which were significantly correlated with the final visual acuity included preoperative visual acuity (0.683), preoperative foveal thickness (0.544), and final foveal thickness (0.643) (p<0.005). Conclusions: Foveal thickness and visual acuity improved until seven months after the vitrectomy in patients with idiopathic ERM. Preoperative visual acuity, foveal thickness, and final foveal thickness had a significant correlation with the final visual acuity.

Crab apple cultivars, ‘Maypole’, ‘Tuscan’, and ‘Manchurian’, were evaluated as potential pollinizers of major apple cultivars, ‘Fuji’, ‘Hongro’, and ‘Tsugaru’, cultivated in high-density apple orchard systems. Numerous cultivar characteristics, including blooming time, pollen germination, fruit set, disease and pest resistance, and selfincompatibility, were examined. The blooming times of both ‘Maypole’ and ‘Tuscan’ ranged from April 19 to May 5, which was 2-4 days earlier than those of the major commercial apple cultivars. PCR analysis did not reveal the presence of any of the S-alleles (S1, S3, S7, or S9) identified in major commercial apple cultivars. In addition, the percentage of the fruit set was high after trees were artificially fertilized with crab apple pollen. Artificially cross-pollinated fruits were of similar or higher quality than open-pollinated fruits. They also demonstrated resistance to apple blotch, sooty blotch, and fly speck. The results indicate that the two crab apples, ‘Maypole’ and ‘Tuscan’ would be potential candidates for pollinizers of major apple cultivars in Korea. Use of the pollen of these crap apples in commercial production will improve fruit quality and promote sustainable and robust fruit production.

The purpose of this study is to focus upon the relationship of the elementary school boys sports performance results, cohesion, satisfaction, and motivation. This thesis tried to find the differences of cohesion, satisfaction, and motivation between the fail group and the success group with footbasebal game. The sample groups researched included 84 sixth year boys at Usan Elementary School in Wonju from April 20 to the end of June in 1993. Seven sample groups were divided into success groups and fail groups according to full league system with 21 games during one month. The data were gathered by questionnarie on team cohesion, their satisfaction, and their paticipant motivation at the end of games. T-verifing method applied for the data to find the difference between success groups and fail groups. Analysis of the data obtained from this research can be summarized as folloings and from results we have to be concerned with following suggestions which may be helpful for our educational reality. First, there were significant differences on the direct cohesion and the social cohesion values between the two groups. Second, there ere also evaluate values of the players' satisfation about their roles and position. Last, there were significant differences of their paticipant motivation with their intimate relationship and their mission. There should be more scientific and elaborate study under long-term plans, and evaluation of the sports groups for elementary students which was not mentioned of this paper.

The way to accomplish effectively the organizational objective lies in the fulfillment of goals on the organizational level as well as individual levels. But most of organizational members are, to a certain degree, confronted with stress and thus have difficulties in attaining the organizational goals. In the organizational study, however, there is no general agreement on the meaning of stress and the methods of measuring it are differently used among the researchers. The purpose of this paper is to offer theoretical framework in stress in order to faciliate a greater understanding definition of stress, general adaptation syndrome(GAS), eustress and distress, stressors, moderators of stress, outcomes of stress, and build the theoretical model. The definition of stress is an adaptive response, mediated by individual differences and/or psychological processes, that is consequences of any external(environment) action, situation, or event that places excessive psychological and/or physical demands on person. The four types of stressors are individual-level stressors, group-level stressors, organizational stressors, extraorganizational stressors. The moderators of stress are social support, coping, hardiness, cognitive complexity, and control. The effects of stress are many and varied. Some, of course, are positive such as self-motivation, stimulation to work harder, and increased inspiration to live better life. However, many are disruptive and potentially dangerous. Shuler(1980) identified three categories of potential effects of stress: physiological response, psychological response, behavior response. Finally based on the major components of stress I develop the theoretical model of stress.
