  • Purpose: This study was designed to construct and test structural equation modeling on healthy menopausal transition in middle-aged women in order to identify variables affecting healthy menopausal transition. Methods: Participants, 276 women, 45 to 60 years of age, with menopausal symptom score higher than 5 on the Korean version of Menopause Rating Scale, were recruited in three cities and one county of Gyeongnam Province. Research data were collected via questionnaires and analysed using SPSS version 18.0 and AMOS version 20.0. Results: After confirmatory factor analysis, one of the observed variables was excluded due to relatively low factor loading. The model fit indices for the hypothetical model were suitable for the recommended level: GFI=.93, CFI=.92, RMSEA=.05. Self-efficacy, self-differentiation, and menopausal symptoms explained 67.7% of variance in menopausal transition, and self-differentiation was the most influential factor for menopausal transition. Self efficacy and menopausal symptoms explained 9.6% of variance in menopausal management, although "menopausal symptoms" was not significant. Conclusion: These results suggest that nursing interventions to improve self-differentiation, self efficacy, menopausal management and decrease menopausal symptoms are critical for healthy menopausal transition in middle-aged women. Continued development of a variety of community-based nursing interventions to facilitate healthy menopausal transition is suggested.

  • Koreans rarely complain of depression or other psychological problems because mental illness is viewed as a stigmatizing and threatening experience. This study examined the relationships among stressful life events, close relationships, self-esteem. and depression in 400 college women aged 18 to 30 years. Depression was positively related to stressful life events (r=.21, p=<.01). Depression and stressful life events were negatively associated with self-esteem (r=-.67; r=-.11, p<.01; p<.05 respectively). Close relationships with women and men friends were each negatively associated with depression (r=-.24; r=-.16, p<.01; p<.05). Close relationships with women and men friends were positively associated with self-esteem (r=.23; r=.20, p<.01). Forty nine percent of variance in depression rates in this sample was explained. After adjustment for degrees of freedom, a total of 49% of the variance in depression was explained by self-esteem and stressful life events. This investigation into the relationships among the variables influencing depression for college women is a critical issue as health professionals need to be aware that college women are at considerable risk for depression. Effective psychosocial interventions are those designed for specific populations to meet unique care needs and since young Korean women may be at considerable risk for depression.

  • The purpose of this study was to investigate the influencing factors on health behavior among patients with coronary artery disease. Method: The subjects were 95 patients who visited the out-patient department of a university hospital for follow-up. The four health belief concepts (motivation, benefit, barrier, seriousness), general self-efficacy, health behaviors on medication, diet, exercise, stress management, smoking, and drinking were measured. Result: There were significant differences in the health behavior scores of subjects according to family support and the experience of surgical procedure. Subjects were found to have a high degree of compliance in taking medication. However subjects reported the lowest degree of compliance in regular exercise. In the multiple regression analysis, surgical procedure and motivation were significant predictors to explain diet. Motivation and barrier were significant predictors to explain exercise. Self-efficacy, motivation and family support were significant predictors to explain stress management. Family support and seriousness explained 16% of variance in drinking. Also, family support explained 30% of variance in smoking. Conclusion: Since predicting factors on each health behavior indicator were different, then nurses should consider these differences to construct strategy enhancing patient's recovery.

  • Purpose: The purpose of this study was to construct a questionnaire to assess male workers' sobriety behavior based on Ajzen's Theory of Planned Behavior (TPB). Methods: A primary questionnaire with 56 questions was constructed based on literature review and structured interview with male workers. The Content Validity Index (CVI) was evaluated by a group of experts, construct validity was tested by principle component analysis, and reliability was evaluated by Cronbach's ${\alpha}$ and the test-retest reliability test. Results: Fifty two questions showed higher than .8 of CVI. Four factors explained 78.71% of the total variance among items for sobriety intention and direct measure, and six factors explained 67.99% of the total variance among indirect measure items and those factors coincided with the variables of TPB in factor analysis. Cronbach's ${\alpha}$ of this questionnaire was .873 and the result of test-retest reliabilty test was relatively reliable. A total of 41 items with 7-point scale were constructed in the final version. Conclusion: This questionnaire was valid and reliable to measure sobriety behavior based on TPB in male workers. It can be useful to evaluate the result of a sobriety program for male workers.

  • Purpose: The purpose of this study was to compare health promoting behavior between working and non-working mothers with infants and toddlers, and to investigate factors affecting the mothers'health promoting behavior. Methods: This descriptive study was conducted through conveniently sampled 403 women who visited the child health clinics at two public health centers. The questionnaire included the Health Promoting Life Style Profile (HPLP) and a visual analogue scale for subjective health status. ANCOVA, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted using SPSS ver. 21. Results: Working mothers' average HPLP score ($2.30{\pm}0.37$) was higher than non-working mother's ($2.15{\pm}0.37$). The score of the physical activity subscale was lowest among the subscales and there was a difference between the two groups. Subjective mental health status was the only predictor of working mothers'health promoting behavior, and it explained 23.2% of variance in health promoting behavior. Subjective mental health status, education, and age were the predictors of non-working mothers' health promoting behavior and they explained 27.2% of variance in health promoting behavior. Conclusion: According to the findings, both working and non-working mothers' health promoting behaviors were low. To promote mothers' health, it is necessary to develop diverse community health promotion programs to support mothers.

  • Purpose: Gamma knife radiosurgery (GKR) requires frame positioning because the treatment target should be as close as possible to the center of the frame. The purpose of this study was to identify the level of pin-fixing (PFP) and removal pain (PRP), and the associated factors with the pain undergoing GKR. Methods: A total of 116 patients who underwent GKR for their brain tumor were recruited from C University hospital located in H city, J province. The level of pain was measured by the 10 cm VAS. Results: The level of PFP and PRP were 6.36 and 3.26 points, respectively. Step-wise multiple regressions found that the group who have not perceived numbness after applying 5% EMLA cream was the highest associated factor with PFP, following the time from lidocaine injection to pin-fixation, which explained 21% of total variance of the level of PFP. On the other hand, a group who did not perceive numbness after applying 10% lidocaine spray was the highest factor with PRP, among female patients, which explained 27% of total variance of the level of PRP. Conclusion: Both of PFP and PRP of the stereotactic frame were moderate so that nurses should consider diverse strategies to reduce pain among patients undergoing gamma knife radiosurgery.

  • This study was performed to show change of fat-free mass(FFM), representing mostly the muscle mass change, and muscle strength with increasing age, and relationship between dietary, exercise behaviors and FFM in healthy middle-and old aged women who are of age over 55 years. The FFM and correspondingly hand grip strength showed significant positive correlation with age. But concentration of serum albumin showed no significant relationship with age. The subjects were categorized into groups according to FFM tertile. The anthropometry such as weight, BMI, fat mass, circumferences of waist and hip, WHR, and hand grip strength decreased significantly in the lowest FFM group. But the albumin level showed no change according to FFM level. The FFM showed significant correlation with nutrient intakes such as energy, carbohydrate, protein, Fe, P, Ca. No association, however, was shown with exercise behavior probably because of no case with resistance exercise habits. The variance of FFM was explained 55.2% by height and carbohydrate intake. The variance of height-adjusted FFM could be explained only 16.2% by intake amount of carbohydrate. In conclusion, the decrease of FFM may cause to reduce muscle strength in female elderly. The increasing nutrient intakes were associated with the increased FFM and may protect from risk of sarcopenia. However, only the carbohydrate intake could influence independently the FFM in middle- and old-aged women. The FFM has no association with endurance exercise habits.
