Nowadays, Stress is becoming an increasingly important concern both in individual and in organization. This is because of the tremendrous results which are caused by it. For this reason, diverse research has been done to reduce the harmful results which are most frequently related to stress in organization. But, there has evenly existed no common definition of stress, yet. Thus, after reviewing many literature about stress, we clarified the concept of stress and suggested the necessity of stress management examining aversive effect on both individual and organization. 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 these models. Based upon th9 theoretical background, we analysed the critical influential factors of stress symptom outcomes through the empirical research. The main findings out of the analysis are as follows: As critical factors of impacting on outcomes, it was indicated that job context stressors such as lack of promotion opportunity and inequality compensation were more important factors than job content stressors such as job variety and job significance. On the other hand, on occasion of physical and mental symptoms, individual factors such as A-personality and self-confidence were the most critical factors to impact on symptoms. In this respect, individual factors were functioned as moderator of relating between stressors and stress symptom outcomes. This tendency was turned out to be more explicit in female. From the preceding analysis, we will give some suggestions for stress management as follows: 1) To set up career planning and developing program. 2) To establish a systematic and equitable reward system. 3) To assign the opportinuity of systematic personality changing. 4) To create a supportive climate and social support. 5) To redesign job. 6) To reduce conflict and clarify roles. This study alas limitation in that it did not fully consider the measurement of stress concept and in that investigating has been conducted in a short Period of time. It is recommended that more systematic researches should be needed through a more careful, detailed observation over long periods of time.

유관호,정순광,김판규 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.6

This study was to find out the way how high school students have participated in current leisure activities recently and to suggest directions to activate leisure activities efficiently in case of weekly 5-school day system. The subjects for this study were male and female students who were working at 8 high school in Seoul. The simple random sampling was used to collect the data. In this study, total 400 questionnaires were distributed and 397 were used for the analysis. For data analysis, SPSSWIN(Statistical Package for Social Science for Window) 10.0 was used. Especially, frequency analysis, independent t-test, one-way ANOVA and Scheffe's multiple range test were used. The results of current leisure participation by high school students are come out as the following: Boy students laid stress on leisure activities themselves but girl students thought leisure facilities important. During leisure activities, boy students spent time with their friends or by themselves while girl students did it with their friends or families. On weekdays and holidays, boy students were spending most of their time doing things for pleasure(like playing Baduk and reading cartoons) or for fulfilling their interests (like taking pictures), but girl students were doing things for pleasure or for social interaction. In spending leisure time, the high school students in their first year spent below 1 hour and those in their second year spent about 2 hours. Healthy students' perception for leisure activities were shown stronger than those for weak students. Healthy students did leisure activities to enjoy their lives while weak students did them in order to get rid of stress. The college entrance system was chosen as a big obstacle to enjoy their leisure activities for all sampled groups. The results of the analysis about leisure activities in case of proceeding with weekly 5-school day system are the following: During weekdays and holidays, boy students wanted to do sport activities and girl students wanted to enjoy sightseeing and cultural activities. Boy students and second year students wanted a billiard room to be installed in school while girl students and first year students wanted a lounge. Boy students spent most of their leisure time at home or in a PC room, while girl students did at home, in a park or a playground. On holidays, high school students in their first year wanted to do sports activities while those in their second year wanted to go to the cultural facilities or do sports activities. During a vacation, first year students wanted to do sports activities and things for pleasure, but those in second year wanted to enjoy sightseeing and cultural activities. I'd like to suggest some desirable directions for leisure activities based on the analysis of the survey result: First, by improving college entrance system, make high schools become places which students can learn with the whole person education. Second, by develope active and energetic programs in leisure activities, make students get a lot of experience of life and build more leisure facilities. Third, since boy students prefer sports activities and girl students are interested in tour or sightseeing in case of weekly 5-school day system, it's necessary to study how to cope with the situation.

In the free flap surgery using microvascular anastomosis, angioraphy is widely used as an integral part of preoperative plans. The necessity of angiography is well extablished. But since there exist many controversies regarding adverse effects of angiography. especially there is no concrete evidence about their effects on the patency after microvascular anastomosis, This study attempts to examine the chronological changes of the arterial intima after systemic injection of ionic contrast media sodium iothamate(Talabrix ) and to evaluate its effects on the patency of microvascular anastomosis. Fifty-nine Sprague Dawley rats were divided into 5 groups according to time interval between contrast media injection and microvascular anastomosis. The time intervals were 1 day, 3 days, 7 days, and 14 days after contrast media injection. The ionic contrast media was injected intraveneously through the tail vein. Left inguinal arteries were anastomosed under an operating microscope after the contrast media injection. After the above procedures and reviewing all the results, we can conclude that ionic angiographic dye causes reversible injuries to the vascular intima, and deteriorates patency of the microvascular anastomosis. And we suggest that a time interval more than at least 7 days to 14 days, between anguographic study and flap transfer is requested.

Behavioral and neurochemical effects of ethanol were assessed in rats after acute administration. Ethanol, 1-5g/㎏, inhibited the memory and rotarod performance, but significantly increased the spontaneous locomotor activity. Ethanol, 1-5g/㎏, did not affect the striatal dopaminergic neuronal activity and cortical noradrenergic neuronal activity. Ethanol, 1g/㎏, decreased the contents of DA(46.7%), DOPAC(66.7%) and HVA(79.2%) in frontal cortex, but increased the contents of DA(125%), DOPAC(116.7%) and HVA(l40%) in hippocampus. Ethanol, 2-5g/㎏, significantly increased the dopaminergic neuronal activity in frontal cortex, while it remarkably decreased the monoaminergic neuronal activity in hippocampus. These results suggest that the activity of cotical dopaminergic neuron play an important role in modulation of the motot activity induced by low does of ethanol, and that the activity of cotical and hippocampal catecholaminergic neurons could be responsible for the control of memory induced by higher does of ethanol.

AIDS is worldwide problem. It has threatens societies and is potentially a big problem among youth. UNAIDS has warned that collective global responses are necessary; with half of the newly infected being children and young people in 1998, educating youth below age 24 is essential. Because of both their unexpected, strong sexual activities and an easjer tendency to change their behavior than adults, UNAIDS emphasizes the importance of prevention education leer youth. In Korea, 4 cases of HIV infection have officially been reported among high school students. Considering the potential seriousness of HIV inflection among youth, the Korean Anti- AIDS Federation (KAAF) began an education programme for Korean youth (middle & high school pupils) as one intervention method in 1993. The purpose of this study is to evaluate the impact of the education programs performed and to develop a better programme. The intervention method used in this study was mainly a lecture in a big or small auditorium or through broadcasting systems using audio-visual teaching aids. The period of this survey was from Nov. 10 to Dec. 26. in 1998. The subjects surveyed were 792 pupils who were sampled from 12 different middle and high schools in Seoul by a two-stage cluster sampling. Self recording the structured questionnaire was used far data collection. Data were analyzed by using a paired t-test to compare the knowledge difference before and after the interrention method. A chi-square test to compare the consciousness difference between pre-post-education results was used, and an ANOVA was used to compare the knowledge difference among the selected groups. Major results of this study are summarized as follows: (1) AIDS knowledge significantly changed after AIDS prevention education. (2) The direct lecture in a big or small auditorium is more effective than an indirect lecture through a broadcasting system or through audio-visual teaching aids. (3) Those who had not seen obscene materials (e.g. pornography films, magazines etc.) acquired much more knowledge than others after AIDS prevention education. (4) Those who had no girlfriend/or boyfriend acquired much more knowledge than the others after AIDS prevention education. (5) As to the attitudes toward chastity, more girls than boys and students who had not seen obscene materials rather than those who already had were liable to support the state ment: "all should remain chase" and their consciousness on "being chaste" changed much more than that of others after intervention. (6) As to the individual evaluation of lectures, 23.1% shows "very good" , 44.1% "good" , 26.9% "normal"'-'thus, the positive evaluation was to 94.2%. The negative response was 5.8%. (7) As to the desire fur AIDS education sponsored by KAAF in the future, more than몫90.5% showed a positive reaction. (8) As to the educators in future education methods, pupils wanted lecturers from outside their schood. (9) Students from vocational high schools have seen obscene materials much more than other groups and the percentage of these who had a girlfriend/or boyfriend was higher than that of the ethers as wello. (10) 90% of those who watched obscene materials responded that they experienced these materials while at middle school and 100% before reaching the second grade of high school. (11) The number of boys who have experienced obscene materials is twice as many as that of girls. (12) The percentage of boys who have a girlfriend is much higher than the percentage of girls who have a boyfriend. (13) Among those who have friends of the opposite sex, 11.1% say that they hare had sexual contact and 20.8% hare experienced kissing and caressing.

고주파 해저면 반사손실의 주파수 종속성 측정

박순식,최지웅,윤관섭,나정열 한양대학교 이학기술연구소 2002 이학기술연구지 Vol.5 No.-

During the last several decades, although there have been lots of efforts to develope the high-frequency bottom reflection loss model, the frequency dependence of bottom loss was not considered in most cases because the sea bottom was assumed to be generally much smoother and lower gradient than the sea surface. However, if the sea bottom is rougher than acoustic wavelength, the scattered field will be increased and the reflected field will be decreased. In this paper, the high-frequency bottom reflection losses were obtained through the measurement of reflected waves from the artificially-made-flat sandy bottom. The experimental data were compared with the values calculated by the forward loss model of Mourad & Jackson. Conseouently, we suggest the frequency dependence of bottom reflection loss. 기존 해저면 반사손실 모델들은 해저면을 해수면에 비해 거칠기와 경사도가 매우 평탄하거나 완만한 경계면으로 가정하므로 주파수에 따른변화를 고려하지 않거나 미약하다고 가정하였다. 그러나 고주파를 사용하는 소오나 시스템의 경우, 음파의 파장에 비해 해저면이 거칠다면 음파는 산란 영향이 증가하게 되므로 상대적으로 반사손실 또한 증가하게 된다. 따라서 본 논문에서는 임의로 모의된 사질 성분의 해저면에서 수십 ㎑ 이상의 고주파들을 사용하여 주파수별 반사손실을 계산하고, 이를 기존의 해저면 반사손실 모델과 비교하였으며, 해저면 반사손실의 주파수 종속성을 제시하고자 한다.
