Objectives : In this study, 233 dental hygiene students in Seoul and Gyeonggi areas were surveyed in order to provide the basic data for more effective clinical practice by investigating the stress they experience during the clinical practice and how they cope with stress; Methods : 5 areas in stress factors as environmental factor, interpersonal factor, role and activity, ideal and value, and the amount of BEPSI and 4 areas in their coping methods as problem-oriented, social support, emotion-oriented, and wishful thinking were measured by Liker 5-point scale. Results : 1. The satisfaction level of subjects on their major was the highest as 'generally satisfied (50.6%),' and their satisfaction level of clinical practice was also the highest as 'generally satisfied (32.6%).' 2. The clinical practice stress was 2.76 points on average, and their stress factors were ideal and value (3.18), environmental factor (2.98), role and activity (2,70), the amount of BEPSI (2.55), and interpersonal factor (2.37). And the way how they cope with stress were 3.29 points on average, wishful thinking (3.71), social support (3.36), problem-oriented (3.13), and emotion-oriented (2.95). 3. The clinical practice stress according to clinical training institutions showed significant differences: university dental hospitals and general hospitals (2.83), dental clinics (2.65), and dental hospitals (2.63). 4. The clinical practice stress showed a negative correlation between the satisfaction level of major and the satisfaction level of clinical practice (p<0.01), and the more satisfaction they had in their major and clinical practice, the less stress during the clinical practice. 5. In the correlation between each subordinate factor of the stress in clinical practice and how to cope with it, interpersonal factor and emotion-oriented factor, the amount of BEPSI and wishful thinking showed a positive correlation (p<0.05). Conclusions : In this study, it is necessary to develop clinical practice program that is to increase satisfaction and provide motivation in order to reduce the stress during clinical training.

The excessive settlement and deformation of disintegrated carbonaceous mudstone (DCM) embankments under dynamic loading have long been problems for engineers and technicians. In this work, the characteristics and mechanism of the plastic deformation of DCM under different degrees of compaction, water contents and confining pressures were studied by static triaxial, dynamic triaxial and scanning electron microscopy testing. The research results show that the axial stress increases with increasing confining pressure and degree of compaction and decreases with increasing water content when DCM failure. The axial strain at failure of the DCM decreases with increasing confining pressure and degree of compaction and increases with increasing water content. Under cyclic dynamic stress, the change in the axial stress level of the DCM can be divided into four stages: the stable stage, transition stage, safety reserve stage and unstable stage, respectively. The effects of compaction, water content and confining pressure on the critical axial stress level which means shakedown of the DCM are similar. However, an increase in confining pressure reduces the effects of compaction and water content on the critical axial stress level. The main deformation of DCM is fatigue cracking. Based on the allowable critical axial stress, a method for embankment deformation control was proposed. This method can determine the degree of compaction and fill range of the embankment fill material according to the equilibrium moisture content of the DCM embankment.

The purpose of this study is to study how college students cope with their stress and how the level of their self-differentiation affects degrees of stress and stress-coping strategies. The questionnaires were handed to 497 college students at Y university in Gyeongbuk Province and the data were analyzed in terms of Cronbach's ${\alpha}$-coefficient, frequency and percentage, t-test, and regression analysis by using the SPSS statistical package. The results of this study were as follows: 1. For stress level, degree of self-differentiation and stress coping strategies of the college students, the average scores were 3.56, 2.53 and 3.49, respectively in 5-point Likert Scale, indicating that the students possess the above-average score for the degree of self-differentiation and stress-coping strategies and the below-average score for stress levels. 2. From examination of difference verification of stress levels based on the degree of self-differentiation and effect of degree of self-differentiation on stress levels, it was found that the higher is the degree of self-differentiation the lower is the stress level. 3. From examination of difference verification of stress-coping strategies according to the degree of self-differentiation and effect of degree of self-differentiation levels on stress coping strategies, we found that the students of higher degree of self-differentiation exercise the more active stress coping strategies. These results show that the degree of students' self-differentiation is a significant variable that influences their stress levels and stress control methods. It is thought that students' self-differentiation functions to minimize their stress and to actively cope with their stressful situation and that a high degree of self-differentiation is a significant mediator variable that is beneficial to students' mental health. It follows from the above observations that while college students in this study seem to possess good degrees of self-differentiation and stress coping capabilities and low stress levels they need to seek for the ways to improve their degree of self-differentiation by seeing into themselves and relationships with others around them. Parents, schools and consultation agencies are required to take an active hand to educate and encourage them to cope with their stress positively.

This study aimed to analyze the six personality factors of rehabilitation therapists and to identify the effects of these factors on their job stress and turnover intention. This study involved physical therapists and occupational therapists as rehabilitation therapists. A structured questionnaire was distributed to rehabilitation therapists, and 186 answered copies were used for data analysis. The results of the survey were as follows: Among the six personality factors, the rehabilitation therapists showed the highest level of honesty-humility and the lowest level of openness to experience. In terms of job stress, the subjects experienced the highest level of stress from job autonomy and the lowest level of stress from relationship conflict. In terms of turnover intention and work motivation reduction, the subjects scored above the median points, showing their high levels of turnover intention. In addition, higher levels of extraversion and agreeableness in the rehabilitation therapists led to a statistically significant reduction in their turnover intention and a statistically significant decrease in most of their job stress factors. Based on these results, organizational management aimed at increasing the personality factors of extraversion and agreeableness is necessary as a measure to effectively manage rehabilitation therapists' job stress and turnover intention.

All clinical nurses are not only faced with the physical and emotional needs of patients but also exposed to the heavy workload. In clinical settings, the nurses' stress becomes more and more critical. Understanding the stress experienced by nurses is essential for planning programs to enhance patient care and to promote nurses health. Many methods to reduce the stress were practiced for patients. In this study, the investigator examined how the imagery influence the reducing the stress of clinical nurses. For this study, the recorded tape for imagery developed in the Society of Rheumatics was applied. In order to evaluate the effect of imagery on the stress of clinical nurse, stress score, serum cortisol, blood pressure, and pulse were measured on 20 clinical nurses for 20 days. The results were as follows: 1. Stress score decreased significantly in the experimental group. And the rate of decrease in stress score was significantly higher in experimental group than in the control group. 2. The level of serum cortisol decreased significantly after the application of imagery. 3. Systolic blood pressure decreased significantly after the application of imagery. These results indicate that after applying the method of imagery on the nurses, stress score, serum cortisol level, and systolic blood pressure were significantly decreased. Therefore, this study proves that imagery is one of the methods to reduce the stress of clinical nurses.

The purpose of this research project is to assess students' stress during clinical rotations and to suggest strategies for enhancing professional skills as well as the quality of clinical rotations among the students of dental technology. The participants included 200 sophomores and juniors from dental laboratory college located in Daegu and Jeju. Data was collected December 7, 2007, and March 7, 2008, by survey samplings. A total of 185 completed surveys were obtained and analyzed for this study. Findings from the study are summarized below. When age and stress were compared, it was found that younger students had higher levels of stress related to their environment, role, and activities. Regarding grade level and stress, students in lower levels were slightly (p<.01) more likely to have stress (Sophomore =2.91, junior =2.49). When the stress level was compared with students' satisfaction with their major, the less students were satisfied, the higher their level of stress was. The study found a slight (p<.05) difference between groups [satisfaction group (M=2.44), group in between satisfaction and dissatisfaction (M=2.58), and dissatisfaction (M=2.82)) in the relationship between satisfaction with the major and overall stress. Again, it appears that stress levels increase as satisfaction with the chosen major decreases. Third, the intensity of stress was affected by the environment in which students practiced, classmate relationships, roles, goals and values, and activities, and areas of performance. It showed that the groups unsatisfied and in-between with the quality of practice have more intensified stress than the group with satisfaction. The study showed a slight (p<.01) difference amongst groups [(satisfaction group (M=2.17), group in between satisfaction and dissatisfaction (M=2.68), and dissatisfaction (M=2.96)) in the relationship between satisfaction with the quality of the clinical rotation and overall stress. It appeared that higher levels of stress were seen with lower satisfaction with the major. Overall, students' level of stress was correlated with age and grade level, level of satisfaction in the major and the quality of the clinical rotation. Furthermore, schools need to focus on improving the environment where students practice, classmate relationships, roles, goals and values, and activities, and areas of performance. Dental laboratory colleges should concentrate on the basic case with the quality of clinical rotation and the chosen major. More skillful teaching and properly assigned clinical rotations and classes, along with a strong practical knowledge base applicable to clinical rotations will be needed in order to address these sources of dissatisfaction.

The purpose of this study was to explore the degree of stress in caregivers caring for CVA patients and the level of daily living performance of CVA patients. The subjects for the study were caregivers of 112 CVA patients who enter a hospital or out-patient-department (OPD) at two Oriental medical hospital in Jeonbuk province. The survey instruments used in this study were Kang's ADL check list for daily living performance of patients and Choi's 4 sore scale for stress of caregivers. The survey was conducted from July 4th to August 30th in 1999. The survey results were analyzed with the Statistical Package for Social Science(SPSS) program and can be summarized as follows: 1. The level of daily living performance for the CVA patients was: 1) complete dependence (M=14.9, 13.1%), 2) complete independence (M=23.6, 20.9%), 3) incomplete independence (M=23.9, 21.0%), 4) incomplete dependence (M=26.6, 25%), 5) dependence and independence (M=23.0, 20.0%). The items for with there was a high level daily living performance were: 1) drinking (M=3.62), 2) eating(M=3.25). 3) position returning (M=3.18) : and the items for which there was a low level of daily living performance were: 1) ascending and descending stairs (M=2.08), 2) walking (M=2.47), 3) dressing and undressing trousers (M=2.55). 2. Degree of caregiver stress was: Mean=2.39 at 40 score. The items for which was a high level caregiver stress were: 1) medical fee (M=3.25), 2) being handicapped or recurrence (M=3.02) : and the items for which there was a low level of caregiver stress were: 1) discontinuity of patient's treatment (M = 1.98). 2) change of home atmosphere caused by patient's disease (M = 1.98), 3) desire of patient's knowing about disease (M= 1.99). 3. There was statistically significant difference in the degree of caregiver stress according to the following caregiver's demographic characteristics: education level (F=3.52, P=0.03). change of caregiver (F=5.41. P=0.02). 4. There was a statistically signifiant difference in the level of daily living performance according to the CVA patients demographic characteristics: patient's paralytic status (F=4.48, P=0.01), duration of disease (t=2.76, P=0.03). 5. There was significant difference in degree of caregiver stress according to the CVA patient's demographic characteristics: CVA status (F=4.75, P=0.01). 6. There was statistically significant difference in the degree of caregiver stress according to the level of daily living performance in CVA patients(r=-0.482, P<0.00).

This study was to identify the correlation between the degree of burden, stress and social support of family caregivers in ICU patient. The subjects were 146 family care givers observed at a general hospital at D city. The level of stress that family caregivers experience the average points of 2.18, which is considered less than average. The level of burden that average point of 2.51. Points for level of subjective feeling ranged from 1.74 to 3.90. The average point of 3.03 is higher than that for objectively recognized feeling. The points for social support that average point of 3.03 for social support proves that families feel positive about the social support they are receiving. The level of stress which shows that the lower the income, the higher the stress. The effect on stress shows significance in subjective feelings of burden, social support, and employment, indicating that they have correlations with stress. Both the feeling of burden and social support have an impact upon the stress that patient families experience.

In order to analyze and investigate in the fatigue behavior of the notched specimens under the two level stressing, the U-notched specimens of structural carbon steel which is generally used is prepared. The obtained results are summarized as follows; (1) The fatigue limit of the U-notched specimens is lower than that of the unnotched. The fatifue notch factor (.betha.) of the U-notched specimens is 1.44 for mild steel and 1.52 for harden steel. The notch sensitivity (q) is 0.68 for mild steel and o.8 for harden steel. That is, these facts show that harden steel is more sensitive to the notch than mild steel. (2) The fatigue life time of the U-notched specimens under the overstressing is shorter than under the constant stressing, and the degree of fatigue life time decrease is different to each stress level; the degree for the high stress level is more than for the low stress level. (3) The fatigue life time of the U-notched specimes under the understressing is longer than under the constant stressing, and the degree of fatigue life time increase for the low stress level is more than for the high stress level.

This study aims at grasping the relativity between laborers' yangseng level and stress so as to present the groundwork for preventive oriental medicine approach in industrial health. The researcher prepared the questionnaire on general character, - health-related yangseng level and chose 632 people to execute Autonomic balance test through heartbeat change. The collected material was analyzed by SPSS and tested by T-test, ANOVA The general yangseng level average is 3.27, morality yangseng 3.91, sleep yangseng 3.39, mind yangseng 3.32, sex life yangseng 3.29, exercise yangseng 3.14, activities and rest yangseng 3.07, diet yangseng 2.95, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. In the aspect of yangseng level: Having a spouse, Non-smoking, Non-drinking, Regular exercising, Sufficient sleeping have higher yangseng levels. In Autonomic balance test, age from 35 to 40 has the highest autonomic activity and job period from 5 years to 10 years has the highest stress resistance. Non-smokers have high autonomic activity and stress resistance. Further, have low autonomic balance, stress index and fatigue strength. In the case of regular exercising person, he/she has high autonomic activity and stress resistance with low stress index. Regarding sleeping time, autonomic balance is the highest when he/she sleeps less than 6 hours. Stress resistance is the highest when he/she sleeps 7 hours and stress index is the highest when he/she sleeps 6 hours. After comparing the relativity between yangseng level autonomic balance test, only exercise yangseng has plus factor on autonomic activity and stress resistance and minus factor on stress index and fatigue strength. Yangseng level has been affected by individual character and daily habits. Also stress is more influenced by daily habits than by individual character. We can find the relativity of exercise yangseng between yangseng and stress which suggests that we need to take measures to win over stresses in individual health in the near future.
