The purpose of this dissertation is to analyze the factors which university students feel as stress in their daily life and the correlation between these and their eating habits. The subject are students enrolled at 'H' university in Asan. There are 801 students who response for this research. We surveyed and analyzed the correlation between the life stress and eating habit of university students. It is analyzed that the objects suffered stress most by 'schooling' and 'job complication.' Surveying the general eating habit of university students, it is found that they do not eat meal regularly, i.e., 'average meals (40.9%)' and 'irregular meal(35.2%).' No significant difference was observed in the regularity of meals between sexes. When it comes to overeating or voracity, male students answered 'sometimes(77.6%)' or 'often(22.5%)', but female students answered 'sometimes(66.2%)' or 'often(28.2%)', which means that female students are more frequent in overeating or voracity. The frequency of eating snack is more than once a day 60.1% in female students and 47.3% in male students, which shows that the rate of female students is much higher than that of male students. Surveying the correlation between stress that male and female university students suffer and the regular meal, we found that both of them tend to eat meal irregularly if they are stressed. Comparing the stress for its factor, male students eat meal irregularly if they are stressed by 'schooling' and female students eat meal irregularly if they are stressed by 'figure.' Checking the correlation between stress and time spent for meal, it is found that while male students eat meal in a hurry when they are stressed by 'job affair', female students do so when they are stressed by 'home economy. Analyzing the correlation between frequency of snack and stress, both male and female tend to eat snack more frequently when they are stressed more. In general, males like the oily food more than male, but when students get stresses, females want to eat oily food than male. Analyzing the correlation between stress and preferential menu, males like green vegetables, sea food in the life get less stresses than others Females like a menu of meat get higher stress than others.

Diabetic nephropathy has been increasing, although blood glucose and blood pressure can be controlled by angiotensin converting enzyme(ACE) or advanced glycosylation end products(AGE) inhibitors in the diabetic patients. We investigated the effect of dietary supplementation of sea tangle on the blood glucose, and pathological scoring of diabetic kidneys in the streptozotocin(STZ) induced diabetic rats. Male Sprague-Dawley rats were divided into normal rats fed control diet and diabetic rats fed control diet or control diet supplemented with powder or oater extract of sea tangle. Diabetes was induced by a single injection of STZ(60mg/kg, ip) in citrate buffer. The animals were fed the experimental diet and water for 13 weeks. Dietary supplementation of sea tangle decreased blood glucose in the diabetic rats. However, dietary supplementation of sea tangle did not affect the antioxidant enzyme activities, MDA content and pathology of diabetic kidneys. These results indicate that decreased blood glucose by sea tangle could not delay the progression of diabetic kidney disease.

목적 : 본 연구의 목적은 다감각환경 적용이 인간의 정서상태에 미치는 영향을 조사하여 스트레스 관리 및 예방법으로서의 의미가 있는지 알아보고자 하였다． 연구방법 : 155명의 대학생을 대상으로 스노즐렌 적용을 하였으며 측정도구로 개정판 대학생용 생활 스트레스 도구와 정서상태 검사(POMS)를 사용하여 치료전후를 비교하였다．스노젤렌 적용방법은 대상을 개별과 그룹으로 무작위로 구성하였고，1회씩 30분의 치료를 실시하였다． 결과 : 정서상태 점수는 치료전 103점에서 치료 후 69점으로 감소하여 유의하게 감소하였고，각 요인별 정서요인 들도 모두 유의한 차이를 보였다．개별치료，그룹치료간의 치료형태에 따른 정서상태 변화의 차이는 없었으며，성별에 따라서는 피곤감을 제외한 모든 요인에서 치료전후의 유의한 차이가 없었다．정서상태 총점과 불안감，우울감，분노감，피곤감 요인이 스트레스와 밀접한 상관관계를 보였다． 결론 : 스노즐렌 적용이 정서상태에 긍정적인 영향을 미친다는 것을 확인하였으며 이를 통하여 정신건강예방 분야에서 작업치료 중재방법으로 활용하기 위한 지속적인 연구가 필요할 것으로 기대된다．

This studies were carried out in summer season to increase high temperature tolerance using hydrogen peroxide treatments on cucumber in greenhouse. The water stress of cucumber in greenhouse by the hydrogen peroxide treatments showed as control〉250 mM〉500 mM treatments in order. The photosynthesis rate of cucumber at 30℃ did not show difference with each hydrogen peroxide treatment in temperature controlled greenhouse. However, the photosynthesis rate of cucumber in the control and hydrogen peroxide treatments at 40℃ was significantly different. The photosynthesis rate of cucumber in combined treatment with 1,000 mg·L-1 CO2 supply and hydrogen peroxide was also higher than control, however, there was no different of photosynthesis in 250 mM and 500 mM treatment. The value of Fv/Fm and Fm/Fo of chlorophyll fluorescent in 500 mM hydrogen peroxide treatment at 40℃ was highest. Also the activity of POD, the antioxidant enzyme, was higher with high hydrogen peroxide concentration than the other treatments. The high temperature limits for growth were 43℃ in the control, 44℃ in the 250 mM and 46℃ in the 500 mM according to analyze chlorophyll fluorescent Fo. The high temperature tolerance in cucumber increased approximately 3℃ by the hydrogen peroxide treatments under this experiment conditions.

The purpose of this study was to examine associations between subjective symptoms of musculoskeletal diseases and the degree of job stress among shipyard workers. The study population was 7,078 employees of the D shipbuilding company. Survey data was obtained from 1,727 employees using a proportional sample according to age and a self-administered questionnaire. The associations were examined with and logistic regression. The main results were as follows: First, the prevalence of musculoskeletal disease in any one part is 59.5% by NIOSH standard. Second, subjects who had worked in the shipyard for over five years had a prevalence of musculoskeletal disease 1.8 times higher than subjects who had worked in the shipyard for less than five years (p<.01). Finally, those who had less support from co-worker's had a prevalence of musculoskeletal disease 1.3 times higher than subjects who had more support from co-worker's (p<.05). Throughout the results, shipyard workers had higher occurrences of musculoskeletal diseases than other manufacturing workers and the risk of musculoskeletal disorder tended to increase with higher job stress. In this research, the plan to reduce musculoskeletal diseases involved making a program and policy which would be able to lower job stress socio-psychologically. This research will prove useful by using basic preventive materials to improve the musculoskeletal health of labores who work in shipyards and similar places.

The purpose of this study was to determine the factors affecting on the home treatment stress in the CP (cerebral palsy) children's mothers. Direct interviews were conducted from March 17 with April 4, 2003 with 97 mothers of CP children. The average level of stress from home treatment felt by mothers with CP children was . Stress-levels were especially high in mothers who were not satisfied with the treatment outcome (p<.05) and whose acceptance of disability was low (p<.01). Stress felt by mothers was low when their health status was high (p<.05). A physical burden was shown to have a significant correlation with the stress of the mothers during the home treatment (p<.01). Mothers with a child of Level 2 disability had lower levels of stress than those with a child of Level 4 or 5 disability (p<.01). The level of stress was higher in mothers who lagged in acquiring technical sufficiency (p<.05). Multiple regression analysis showed that one factor affecting the stress felt by mothers with CP children was the degree of acceptance of the disability (p<.01). Programs that can reduce the stress levels of mothers with CP children through home treatment and secure social systems such as professional help and economic compensation, need to be developed. Active policies should be established and executed for these mothers since stress felt by mothers significantly affects the consistency and effectiveness of treatment provided at home.

본 실험은 가지과 작물의 염 스트레스에 대한 생장 특성 및 생리적 반응을 구명하기 위하여 수행되었다. 생육단계에 따라 NaCl을 농도별로 처리한 결과는 다음과 같았다. 초장, 생체중 등 생육은 유묘기 및 영양 생장기 모두 NaCl 농도가 높을수록 모든 작물에서 억제되었다 특히 토마토 및 가지에서는 NaCl 40mM 이상에서, 그리고 고추에서는 20mM 이상에서 작물의 생육이 크게 억제되었다. 수량은 토마토 및 가지에 서는 NaCl 20 mM 이상에서, 그리고 고추에서는 10 mM 이상에서 감소하였다. 이러한 수량감소는 낮은 농도에서는 착과수의 감소에, 그리고 농도가 높을수록 착과수의 감소와 더불어 평균과중의 감소의 영향이 컸다. 광합성 속도는 NaCl 농도가 높을수록 감소하는 경향이었으며. 고추가 가장 낮았고, 토마토, 가지 순으로 낮았다. 잎의 수분포텐셜과 기공 전도도도 광합성과 같은 경향을 나타냈다. 경엽의 무기 양분 함량에서는 질소, 인산, 칼슘, 마그네슘 및 칼륨 함량은 NaCl 농도가 증가할수록 감소하였으나 Na 및 Cl 함량은 증가하였다.

본 연구에서는 알코올 섭취 방법이 간과 뇌에서 산화적 스트레스 유발 정도에 미치는 영향을 알아보고자 흰쥐에 5%의 에탄올이 함유된 물을 1개월간 자유로이 섭취하게 하는 방법 또는 2.5g/㎏의 에탄올을 1일 1회 1개월간 경구 투여하는 방법 등 알코올 투여 방법을 달리하고 간, 대뇌 및 소뇌에서 지질과산화 반응과 비타민 E의 함량 변화를 비교하였다. 5%-EtOH의 간조직에서는 비타민 E의 함량이 증가하고 지질과산화물은 변화가 없었으며, 2.5g-EtOH군의 간조직에서는 비타민 E의 함량은 변화가 없으나 지질과산화물은 유의적으로 증가하였다. 뇌 조직에서는, 5%-EtOH군의 대뇌와 소뇌 모두에서 지질과산화물이 증가하고 비타민 E의 함량이 감소하였다. 또한, 2.5g-EtOH군의 대뇌와 소뇌에서도 지질과산화물이 증가하고 비타민 E의 함량이 감소하였으며 그 정도는, 5%-EtOH군에서 보다 큰 경향을 보였다. 결론적으로, 간에서의 지질과산화 반응 및 비타민 E의 함량은 알코올 투여 방법에 따라 다양하게 나타났으나 대뇌와 소뇌에서는 본 연구에서 실시한 투여 방법 모두에 의해 산화적 스트레스가 유발되었다.

The purpose of this study is to investigate effects of the police, prosecution and the others's social support on stress responses and correction of the juvenile delinquents. To accomplish these purposes, this study used sample of 546 juvenile delinquents who are in the process of the juvenile justice. Social support and correction were assessed with an instrument designed for this study. Juvenile delinquents were assessed using the following variables: ⑴ perceived social support scale, specially social support types (esteem support, emotional support, informational support), social support providers (parents, relatives, friends, teachers, community) and police and prosecution's social support. ⑵ correction scale, specially social stigma, social deprivation, self reflection, legal consciousness, self concept. The resulting scale of the instrument had good internal reliability and was scored to show that high scores indicated a willingness to access. To examine this purpose, Mean, standard deviation, Two way ANOVA were conducted. The results are as follows: First, The effects of the police and prosecution's social support on stress responses did make significant difference. The less police and prosecution's social support they had, the more stress responses such as anger, anxiety, guilty feeling and resentment appeared. Second, the effects of the police and prosecution's social support on correction did make significant difference on the social deprivation, legal consciousness and self reflection. Therefore, the system like Youth Counseling Center which provides counseling, consultation, and information to the youth and their parents in early stage of the police and prosecution should be activated. And, Government should develope a formal and informal social support network for the juvenile delinquents.

Maternal stress was very common symptom that every pregnant women could have experienced during pregnant period. We found that the causative factors of stress for subjects were physical change(50.8%), family relationship(13.6%), change of body image(7.4%), concern baby(6.8%), economic difficulties(6.4%), depress(4.3%), morning sickness(3%), and miscellaneous(3.5%). According to our study, maternal stress during the first trimester negatively correlated with food and nutrients intake of pregnant women and gave low weight gain during pregnancy and low birth weight of infants. It also significantly correlated with monthly income(p〈0.001) and monthly food cost(p〈0.001) during pregnant period. Mean intake of Calcium and Iron were 47~60% of RDA and 35~48 of RDA, respectively. With the Iron supplement the total intake of Iron exceeded 100% of RDA. We also found majority of food items, except seaweeds, fruits and vegetables, were negatively correlated with maternal stress during three trimesters. Additional support system projected by professionals in health-care field could mediate maternal stress and lead to healthy pregnancy outcome.

산성비의 주요 성분인 So2가 peroxidase 활성에 미치는 영향을 조사하기 위하여 다양한 농도의 Na2SO3를 포함한 배지에서 벼(Oryza sativa) seedling을 배양하였다. Na2SO3는 볍씨의 발아를 억제시켰으며, 볍씨의 발아율을 50%감소시키는데 필요한 Na2SO3의 농도가 pH 7에서는 300μg/ml, PH5에서는 8μg/ml 이었으나, pH 3
