The main purpose of this study was to explore the effect of the stress of hospitalization on the sleep pattern. Additionaly, this study was also to demonstrate how Johnson's nursing model may be applied to as nursing process. 104 hospitalized patients on surgical and medical wards were asked to rate 49 stress producing events associated with experience of hospitalization and sleep pattern scale. Five university hospitals were used as the setting for this study. Data for the study were collected by patient interview during hospitalization, self-reports and review of charts. For the analysis of the data, the pearson's correlation analysis of covariance and regression analysis were used. The results of this study were stated as follows; 1. The mean of the hospital stress scores was 111.261(S.D.=26.160). This means that the level of the hospitalization stress is high. The mean of the sleep pattern scores was 12.204(S.D. =2.615) This means that the characteristic's of the sleep pattern is poor. 2. The relationship between the hospitalization stress and sleep pattern was statistically significant at .01 level. 3. The effect of the hospitalization stress influenced strongly on the sleep pattern after sex, trait anxiety as covariates controlled. 4. The hospitalization stress revealed a 12% pre-diction as an influenced factor for the sleep pattern. Therefore, It can he said that the hospital stress did contribute significantly to the characteristics of the sleep pattern. Johnson's model can he also said that it is useful for the the assessment and diagnosis in nursing process.

Objectives: The study was conducted to investigate the relationship between several stress measures in everyday life, emotional eating behavior, and dietary pattern (snacks, fatty foods, sweet beverages, fruits and vegetables) in school-aged children. Methods: One hundred and ninety-four students of an elementary school located in Seongnam City participated in the study. The students responded to the survey questionnaire by self-report, which consisted of items regarding general characteristics, height, weight, dietary habits, frequency of consuming healthy (fruits and vegetables) and unhealthy foods (snacks, fatty foods, and sweet beverages), emotional eating behavior, and daily stress. Correlational analysis was performed to examine the relationship between stress, emotional eating behavior, and dietary pattern, and Poisson and logistic regression analyses were conducted to investigate the effects of stress on dietary pattern. Results: Positive correlations were found between all stress factors and emotional eating behavior and between the friend and personal factor (one of the stress factors) and the consumption of sweet beverages. The frequency of consuming sweet beverages was 2.6 times higher in the high stress group than in the low stress group (95% CI). Conclusions: Children's daily stress was associated with emotional eating behavior and undesirable dietary pattern such as consumption of sweet beverages.

IC 패키지와 같이 두께가 수백 마이크로미터 정도로 매우 얇은 기판에서 뒤틀림 불량을 일으키는 가장 큰 원인은 응력이다. 일반적으로 응력은 기판 위에 서로 다른 물질을 적층할 때, 결정구조 및 그에 따른 열팽창 계수의 차이로 인해 발생한다. 본 연구에서는 사각형의 박막 패턴이 적층된 기판에 발생하는 응력의 거동을 수치적으로 분석하였다. 먼저 기판 변위를 구하고, 이를 이용하여 기판 변형률과 응력을 구하였다. 박막 패턴의 가장자리에 인장력이 집중된 경우, 박막 패턴의 가장자리를 중심으로 수직 응력과 전단 응력이 발생한다. 수직 응력은 박막 패턴의 가장자리와 꼭짓점 부근에 발생한다. 전단 응력도 박막 패턴의 가장자리를 중심으로 발생하나 수직 응력과는 달리 꼭짓점 부근에는 나타나지 않는다. 또한 가장자리를 중심으로 전단 응력의 크기와 방향이 바뀌는 것을 확인할 수 있었다. 박막패턴 가장자리 힘이 동일할 때, 수직 응력은 전단 응력에 비해 10배 정도의 값을 나타내었다. 이는 뒤틀림 불량을 일으키는 가장 큰 원인이 수직 응력임을 나타낸다.

Purpose: The present study was intended to assess stress, depression and fatigue of nurses working for university hospitals and to reveal its association with the type A behavior pattern. Method: The self-administered questionnaires were given to 810 nurses employed in 4 participating hospitals located in Daejeon City. The questionnaire items included sociodemographic, job-related, and the type A behavior patterns as independent variables and the PWI, SDS and MFS as dependent variables. Result: The proportion of the type A behavior pattern was 24.3% of subjects, in the degree of stress, high risk stress group was 87.0%, in the degree of depression, normal group was 60.9%, in the degree of fatigue, high risk fatigue group was 48.6%. The degree of stress, depression, and fatigue were significantly higher in the type A behavior pattern group then the type B behavior pattern group. The type A behavior pattern was significant positive correlation with stress, depression, and fatigue. The degree of stress(OR=1.2, 95%CI=1.167-1.262), depression(OR=1.1, 95%CI=1.11-1.17) and fatigue (OR=1.1, 95%CI=1.04-1.06) were significantly higher for the type A then the type B behavior pattern group. Conclusion: The degree of stress, depression, and fatigue were significantly higher in the type A then the type B behavior pattern group.

In this work, the combined meandering-pattern stress-sensors were presented in order to achieve the high sensitivity of stress sensors. Compared to the previous works, which have been using the single meandering-pattern stress-sensors, the sensitivity was approximately observed to increase by 30%~70%. Also, in this paper, more simple and convenient stress-measurement method was presented.

The purposes of this research are to find out general trends of mother-adolescent communication and family stress to estimate the differences of communication patterns and family stress according to sociodemographic and communication variables and to analyze communication variables influencing on family stress. The samples were selected from high school students and their mothers and 342 couples were used in final analysis. Barnes & Olson(1982)'s parent-adolescent communication scale(PACI) and McCubbin(1981)'s family stress scale(FILE) were used to measure mother-adolescent communication pattern and family stress. The data were analyzed by frequency, percentage, mean, Chi-square, F-test Duncan-test, multiple regression, Pearson's r, and Chronbach's α. The result are summerized as follows: 1) Mothers highly perceived mother-adolescent open communication pattern but adolescents highly revealed mother-adolescent close communication pattern. The general trends of family stress showed that adolescents stress is higher than mothers. 2) Communication patterns showed significant differences in mother's age, adolescent's sex and communication variables in mother's education and conversation variables. Generally when mothers and adolescents communicated insufficiently and were not satisfied with communication patterns family stress was increased. 3) Family stress was significantly different in communication patterns. Form the regression analysis it was found that communication patterns are crucial to family stress. Especially open communication pattern between mothers and adolescents was the most important among the communication patterns for family stress was reduced.

Stress and fatigue are general physical aspects of our daily lives. It has been shown that physical therapists have different levels of job stress and fatigue according to the type A/B behavior patterns. This study collected data from 212 physical therapists between October 28 and November 23, 2016 using an anonymous, self-administered questionnaire. The study results showed the proportion of physical therapists with the Type A behavior patterns(TABP) was 18% greater than that of physical therapists with the Type B behavior patterns(TBBP). In this study, physical therapists with TABP were compared with physical therapists with TBBP. The results indicated that physical therapists with TABP were more inclined to experience higher levels of overall job stress and fatigue from the following stress factors: physical environment, job requirement, and job autonomy. Therefore, the stronger the tendency toward TABP, the stronger the feeling of job stress and fatigue from physical environment, job requirement, and job autonomy. Those with a tendency toward TBBP showed positive correlations between job requirement and the total job stress score; thus, the stronger the tendency toward TBBP, the stronger the feeling of overall job stress and fatigue from job requirement. This study suggests that it is necessary to manage the job stress and fatigue of physical therapists with both TABP and TBBP and to manage the job stress and fatigue of physical therapists with the type A behavioral pattern.

This study was attempted to provide the basic data concerning development of stress management program for hospital nurses, and to focused on the analysis of job stress and social support according to the types of behavior pattern. The subjects were 296 staff nurses at a general hospital in Seoul. Data were collected with self-reported questionnaires and analyzed by SPSS-PC+ 8.0 win for descriptive analysis and ANOVA analysis. The results of this study indicated that; 1) The perceived job stress was negatively correlated with social support and was positively correlated with TABP. 2) The score of the perceived job stress was higher in TABP nurses than TBBP. The TABP nurses usually perceived more support from peers than from supervisors These results showed that the staff nurses who supported from supervisor felt less stress, and the score of the perceived job stress was higher in TABP nurses than in TBBP. So the differences in social support and job stress according to the types of behavior pattern must be considered significantly in development of the staff nurses' stress management program. Also it was needed to develop the strategies that TABP nurses was effectively supported by the supervisor.

Effective notch stress, as an approach to evaluate the local stress at a notch (weld toe or root), is defined as the total stress assuming linear-elastic material behavior. This method can be effectively used to evaluate the fatigue performance of welded joints. In this study, finite element analysis results using the effective notch stress method were correlated with fatigue test results of rib-to-deck welded joints in a steel orthotropic bridge deck. Effective notch stress approach provided a good correlation with the crack pattern observed in the full-scale fatigue test. A higher effective notch stress at the critical weld toe than at the weld root was consistent with the dominant crack pattern observed at the weld toe during testing. The effective notch stress at the toe on the deck plate was about 80% higher than that on the rib; no cracks at the weld toe on the rib in the testing were observed. Maximum effective notch stress at the weld root occurred on the upper side of the root notch, which indicates that cracks are more likely to propagate into the deck plate, not into the weld metal. This is also consistent with the observed crack pattern in which the crack from the root propagated upward into the deck plate. No such crack pattern, propagating into the weld metal, was observed in the testing.
