The recent problems of adolescents are leading us to amphasize school mental health program. Therefore, for the first step of that program, this study was attempted to find out the students' daily life stress, their adaptation beharior to resolve that stress, and their self-concept which has an effect on that beharior, to analyze the relationship among those three variables, and to provide basic data which help maintain and promote students' adaptability and mental health. The subjects were 4 classes each grade, 743 students who were chosen as a sample subject among the total of 3,250 students of a junior girls' school in Seoul by stratified sampling method. The Oquestionnair surrey was done from April 1, 1985 to April 6, 1985. The instruments were (1) a part of Junghoon chois' perceptual Orientation Scale for measuring self-perception of students, (2) Rosenberg's Questionnair for measuring students' evaluation of self-esteem, (3) modified Bell's Adoptive Behavior Questionnair, and (4) the Measuring scale for stress developed by the investigator. The collected data were analyzed by using descriptive statistics, x²-test, t-test, ANOVA, and Pearsons' Correlation. The results are summarized as follows: 1. The range of mean score of self-concept, stress, and adaptation beharior is 1-5 respectively. The mean score of self concept was 3.45. The mean score of stress was 2.53, and the degree of stress was in order of the problem of study and grade marks, girl friend, appearance, and relaxation. The subjects preferred effective long-term adaptation method (Mean=2.81) to ineffective short-term adaptation method. (Mean=2.47) 2. The self-concept had the highest degree when students were 1st grade, in good health condition, taking high grade marks, both parents existing, fathers' educational level being above college, and being in high economic status. The degree of stress was significantly high when students were 3rd grade, in poor health condition, having low grade marks, being in poor economic status, and fathers' educational level being under elimentary school. In relation with adaptation method, 1st grade students used more sbort-term and long-term method, and when students had high grade marks, being in high economic status. they used more long-term adaptation behavior. 3. Two Hypotheses of this research were tested: Hypothesis 1. "The higher the students' self-concept is, the more they use long-term adaptation method." was accepted. (r=.2482, p<.01) (t=-4.99, p<.001) Hypothesis 2. "The higher the students' stress is, the more they use short-term adaptation method." was accepted. (r=.2897, p<.01) (t= -7.51, p<.001) In conclusion, a person in charge of school health can help students to adapt effectively by planning and implementing methods which highten their self-concept and lower their stress. But because the correlation among self-concept, stress and adaptation behavior was at a low level, I think that the study, which confirm the relationship of those three variables, is needed.

This study aims to investigate the stress factors of students in Dental Hygiene Department who will soon take the national examination, corresponding countermeasures and relationship of internal and external personality. On the basis of the results from investigation, this study will identify the methods to effectively cope with stress and to take the national examination with more positive thinking for the students and faculty members in Dental Hygiene Department, who have to pass the difficult test, the national examination. The structured questionnaires were given to junior students in Dental Hygiene Department in three colleges, to identify the stress factors, methods to deal with stress and A/B personality types. For the stress factor by field, the M college showed significantly higher stress about curriculum and assignment than the C college. In the stress factor analysis by item, the lack of information on national examination in the test area, all items in learning environment, a quantity of assignment that doesn't help the preparation of national examination in the assignment area, and lack of information on employment in job area demonstrated the significant difference(p<0.05). For the methods of subjects to deal with stress, several subcategories of long-term and short-term adaptation had significance. In case of the methods to deal with stress by personality type, B type in the short-term adaptation method in M college and A type in the long-term adaptation method in C college were significantly higher(p<0.05). As for the correlation between the population sociological features and stress factors by personality type, health status had the high correlation with test in the test area. In other areas, the travel hours to school showed the significant correlation. The higher the records were, the longer the travel hours were and the better the health status was, the higher the long-term adaptation method scores were. Moreover, the personality of A type showed the higher scores in the long-term adaptation method than that of B type. The health status and personality type showed the significant correlation(p<0.05). In conclusion, it is required to prevent any situations b identify the personality type and stress reasons of the students in Dental Hygiene Department who will take the national examination soon. The additional requirement is the continuing interest and counseling of faculty members to help students to cope with stress with positive attitude.

In order to predict stress intensity limit of high-temperature creep structures, creep work-time equation, defined as $W_ct^P=B$, was used, and the results of the equation were compared with isochronous stress-strain curve (ISSC) ones of ASME BPV NH Code. For this purpose, the creep strain tests with. time variations for commercial type 316 stainless steel were conducted with different stresses; 160 MPa, 150 MPa, 145 MPa, 140 MPa and 135 MPa at $593^{\circ}C$. The results of log $W_c$ and log t plots showed a good linear relation up to $10^5$ hr. The constants p, B and stress intensity limit values showed comparatively good agreement to those of ASME NH ISSC. It is believed that the relation can be simply obtained with only several short-term 1% strain data without ISSC which can be obtained by long-term creep data.

In order to investigate the mechanism of adaptation to long-term heat stress, six female buffalo calves of about 7 to 8 months age, were exposed to the cool-comfort environment (THI 65) for 21 days to obtain normal values of blood acid-base. An adaptive response of acid-base regulation was determined to long term (21 days) exposure of buffalo calves to hot-dry (THI 80) and hot-humid (THI 84) conditions. Higher rectal temperature and respiratory rate was recorded under hot-humid exposure compared to hot-dry. Significant reduction in the rectal temperature and respiratory rate on day 21 of hot-dry exposure indicated early thermal adaptation compared to hot-humid. Decreasing rectal temperature and respiratory rate from day 1 to 21 was associated with concurrent decrease in blood pH and pCO2. Increased plasma chloride concentration with low base excess in blood and in extracellular fluid suggested compensatory response to respiratory alkalosis. Reduced fractional excretion of sodium with increased fractional excretion of potassium and urine flow rate indicated renal adaptive response to heat stress.

Numerical modeling and scenario composition are needed to characterize the geological environment of the disposal site and analyze the long-term evolution of natural barriers. In this study, processes and features of the hydro-mechanical behavior of natural barriers were categorized and represented using the interrelation matrix proposed by SKB and Posiva. A hydro-mechanical coupled model was evaluated for analyzing stress field changes and fracture zone re-activation. The processes corresponding to long-term evolution and the hydro-mechanical mechanisms that may accompany critical processes were identified. Consequently, practical numerical methods could be considered for these geological engineering issues. A case study using a numerical method for the stability analysis of an underground disposal system was performed. Critical stress distribution regime problems were analyzed numerically by considering the strata's movement. Another case focused on the equivalent continuum domain composition under the upscaling process in fractured rocks. Numerical methods and case studies were reviewed, confirming that an appropriate and optimized modeling technique is essential for studying the stress state and geological history of the Korean Peninsula. Considering the environments of potential disposal sites in Korea, selecting the optimal application method that effectively simulates fractured rocks should be prioritized.

Purpose: This study is a mixed methods research that was conducted to verify factors affecting the working experience of community-based long-term care hospital workers during the COVID-19 pandemic. Methods: The study was carried out from July 19 to November 3, 2021 for 340 nurses who worked at 10 long-term care hospitals located in G city. Results: As the study results, factors that affected job stress of the workers working at community-based long-term care hospitals included job satisfaction (β=-.27, p<.001), work demand (β=-.25, p<.001), fatigue (β=.19, p=.001), and cooperation and leadership (β=-.12, p=.049). It was found that the participants were struggling with physical and mental stress caused by the increased workload due to the preventative measures taken to stop the infection and spread of COVID-19. Despite this, they accepted their situation as necessary to overcome the pandemic and shared the quarantine guidelines of the government and community health centers while actively responding to prevent the spread of COVID-19 under the leadership of their supervisors. However, they were experiencing psychological and emotional burnout in the prolonged pandemic situation. Conclusion: It is considered necessary to help relieve their stress and provide psychological and mental support by adopting a policy to develop and apply comprehensive programs.

본 연구에서는 half-life가 긴 DHEAS를 스트레스 관련 호르몬으로 보고 다음과 같은 실험을 실시하였다. 실험 1) 매일 30분씩 3주간 장기 고온스트레스 부과 후 4일간의 휴식을 준 생쥐에서의 DHEAS 변화를 관찰하여 이를 cortisol과 비교하였다. 그 결과 cortisol의 경우 장기 고온스트레스 부과 후 즉시 혈액을 채취한 그룹(LW)과 4일간의 휴식 후 혈액을 채취한 그룹(LR) 모두 대조군(C)에 비해 유의적 차이를 나타내지 않았다. 이에 반해 DHEAS는 장기 고온스트레스 부과 후 즉시 혈액을 채취한 그룹(LW)에서 대조군에 비해 유의적인 감소(p<0.05)를 보였으며, 4일간의 휴식(LR)을 준 후에도 여전히 유의적인 차이를 유지하였다(p<0.05). 실험 2) 고온스트레스를 매일 30분씩 1주간, 2주간, 3주간 부과한 그룹에서의 휴식 기간별 혈청 DHEAS농도 차이를 측정하였다. 그 결과 스트레스 기간이 길어질수록 혈청 DHEAS농도가 감소되는 경향을 나타내었으며, 10일간의 휴식을 주었음에도 2주간, 3주간 부과한 그룹에서 여전히 대조군에 비해 낮은 농도를 유지하였다(p<0.05). 이러한 결과로 보아 cortisol을 이용한 기존방식은 스트레스가 사라진 후의 상태를 파악하는데 어려움이 있었던데 반해, DHEAS는 변화된 상태를 지속적으로 유지함으로써 스트레스가 사라진 후의 상태를 파악하는데 적합한 호르몬으로 판단된다.

Purpose: This study developed a structural model for explaining and predicting terminal care performance in long-term care hospital nurses. The model was based on the stress integration model of Ivancevich and Matteson(1980) and the results of previous studies. Method: Data was obtained from August to September 2022 from 267 nurses in 13 long-term care hospitals in G-do. Results: Results of model verification for this study, revealed that factors directly affecting the terminal care performance of long-term care hospital nurses were nursing work environment(β=0.43, p<0.001), death anxiety(β=-0.29, p<0.001), and terminal care stress(β=0.22, p=0.003). However, the attitude toward nursing care of dying(β=0.07, p=0.287) had no effect on the terminal care performance. Conclusion: The results of this study, confirmed the necessity of improving an individual's perceived nursing work environment, continuous education related to terminal care to reduce death anxiety, and an interventional approach for enhancing terminal care performance.

Objectives : The purpose of this study was to examine the relationship of the self-efficacy of dental hygiene students to their stressors and ways of stress-adaptation patterns. Methods : The subjects in this study were dental hygiene juniors in four selected colleges located in the metropolitan area. Results : 1. They got a mean of 3.22 in self-efficacy. They gave the highest mark(3.50) to an item 'I can attain it if I set a primary goal.' 2. They got a mean of 3.18 in stressors. Among the stressors, task assignments(3.74) were identified as the greatest stressor, followed by the curriculum(3.25), learning environments(3.16), prospects of employment (3.07) and test anxiety(2.95). 3. They got a mean of 2.02 in stress-adaptation method. They got 2.31 and 1.72 in long-term and short-term adaptation respectively, which showed that long-term stress adaptation method were more prevailing than short-term ones. 4. As a result of analyzing whether there would be any gaps in self-efficacy according to general characteristics, statistically significant gaps were found in that regard according to experience of preparing for college admission after leaving high school, academic standing, satisfaction with the department of dental hygiene and prospects of employment(p<.05). 5. As a result of checking the relationship of their self-efficacy to their stressors and ways of stress adaptation method, there were statistically significant differences in that aspect according to examinations and prospect of employment(p<0.05). As for ways of stress adaptation method, there were statistically significant differences in long-term adaptation method (p<0.05). Conclusions : As it's found that the level of the self-efficacy of the dental hygiene students was linked to the efficiency of their ways of stress adaptation method, the development and implementation of programs geared toward boosting the self-efficacy of dental hygiene students are required to teach them to successfully cope with various kinds of stress that they are likely to face after getting a job.
