Purpose: The purpose of this study was to identify the effects of a supportive program on uncertainty, anxiety, and maternal-fetal attachment in high-risk pregnant women. Methods: The participants were 59 high-risk pregnant women admitted to the maternal-fetal intensive care unit. The control group (n=30) received usual treatment and antenatal care, while the experimental group (n=29) received an additional supportive program. Uncertainty, anxiety, and maternal-fetal attachment were measured in both groups prior to the intervention and at 3 days and 10 days after the intervention (or at discharge). Data were analyzed with the t-test, chi-square test, repeated-measures analysis of covariance, and the Greenhouse-Geisser correction in SPSS version 23.0. Results: A supportive program including information provision, nutritional care, emotional care, and exercise care was developed from the literature. All variables except women's length of stay were found to be homogeneous the between experimental and control groups in the pre-test. Length of stay was calculated as a covariate for testing hypotheses. There was a significant difference in state anxiety over time between the two groups, while there were no differences in uncertainty or maternal-fetal attachment. Conclusion: This supportive program was identified as an effective nursing intervention on state anxiety in high-risk pregnant women during their stay in the maternal-fetal intensive care unit. It is suggested that nurses could apply this program to alleviate high-risk pregnant women's state anxiety, and that this program could be modified to be more effective on uncertainty and maternal-fetal attachment in high-risk pregnant women.

Motivation has been identified as an important factor predicting long-term outcomes of alcohol abuse treatment. Whether a patient agreed on his/her inpatient treatment at time of hospitalization could be an indicator of their motivation for treatment. This study focused on this aspect of treatment motivation and examined whether this factor predicts post-discharge abstinence. A sample of 145 individuals who were hospitalized for alcohol abuse treatment participated in the baseline data collection, of which only 66 successfully completed the 8 month follow-up telephone interview. The findings of survival analysis suggest that voluntarily admitted individuals had significantly longer duration of post-discharge abstinence compared to their counterparts. A Cox proportional hazards regression model revealed that voluntary admission and family support were significant predictors for post-discharge relapse of drinking, after controlling for the effects of marital status, living alone, and working status. Implications for social work practice are discussed.

This paper looks critically, in the light of the Capital Controversies of the 1950s and the 1960s, at the Neoclassical claim that the Funded-Pension system is economically superior to the Pay-As-You-Go (PAYG) pension system. This claim rests crucially upon the inverse relation between the rate of interest and the volume of investment (the investment demand function) and the positive relation between the capital intensity and labour productivity (the 'intensive- form' production function), The Capital Controversies proved that the two relations do not always hold; then, the claim in question loses much of its ground. Further, the absensce of the relations makes plenty room for effective demand in determining the level of income and the volome of employment even in the long period. This positive role of effective demand in the long period highlights the problems of the Funded-Pension system and, at the same time, supports the competitiveness of the PAYG pension system.

The purpose of this study is to understand the context of mental hospital admission and discharge related with the stakeholder and to find out issues about public management on mental health disabilities. To this process, the more effecive alternative policies for mental health will be offered. As a research tool, the qualitative study was used, and the 6 case were analyzed. Through this study, we find 5 theme such as admission type occurred outside public management, uneffective public management in mental hospital treatment, long-term treatment mechanism occured in mental hospital, helplessness and role distortion of public follow-up system. According to the mental health law, mental hospital admission and discharge on mental health disabilities is to managed public system. But public management with mental health disabilities did not work on. In this results, we are find infringement on mental health disabilities. According to these findings, several suggestions are offered for better policies about admission and discharge procedures managed by public system.

The purpose of this study is to examine the recovering gambling addicts' overcoming process on their hardships of life which hamper their recovery. For this study, we had one to one depth interview with 10 participants who had overcome their hardships of life after stopping gambling. The data gathered from the interviews were analysed following the grounded theory process suggested by Strauss and Corbin. As a result, 131 concepts were constructed, and they were classified into 32 subcategories and 14 category. We presented "overcoming of the hardships of life through the acceptance of reality and re-determination" as a core subject which connects the whole concepts. Based on the research outcomes, we proposed some policy and practice intervention methods such as economic self-support program, social security service, and triangle support system by counselor-family-peer recovering addicts.

Purpose: This study aimed to identify the degree of accident prevention behavior, self-esteem, self-regulation ability, and social support among middle-school students, and investigate factors influencing their practice of accident prevention behaviors. Methods: The participants were 174 students from two middle schools located in J city. Data were collected from December 28, 2017 to February 9, 2018 using self-reported questionnaires. Results: The mean score were $3.08{\pm}0.37$ of 4 for practice of accident prevention behaviors, $3.07{\pm}0.57$ of 4 for self-esteem, $3.69{\pm}0.48$ of 5 for self-regulation ability, and $3.38{\m}0.75$ of 5 for social support. Positive correlations were found among self-regulation ability, self-esteem, social support, and practice of accident prevention behaviors. The factors influencing the practice of accident prevention behaviors were personality (being 'haste') (${\beta}=-.20$, p=.003), self-regulation ability (${\beta}=.48$, p<.001), and social support (${\beta}=.23$, p<.001). These factors explained 39.0% of the variance in practice of accident prevention behaviors. Conclusion: It was found that the middle-school students engaged in prevention behavior to an extent that was insufficient to prevent accidents. Therefore, it is necessary to develop intervention strategies to improve the practice of accident prevention behavior among middle-school students, considering self-regulation ability, social support, and personality, which affect the practice of accident prevention behaviors.

Purpose: This study aimed to identify the effects of utilizing Smartphone Application Peer Support (SAPS) on health behavior and body mass index (BMI) among overweight or obese breast cancer survivors (BCS). Methods: A nonequivalent control group with a non-synchronized design was utilized and 36 participants (experimental group 14, control group 22) were recruited from August 2017 to September 2018. Participants were 40~65 years old, overweight or obese, had completed primary cancer treatment within the 12 months prior to the study, and had not done regular exercise during the last 6 months. The 3-month SAPS consisted of exercise and diet education (once p/2 weeks), peer support (once p/week), and self-monitoring using smartphone applications (5 times p/week). All participants underwent assessments at baseline, right after SAPS, and at 3 months after SAPS. Data were analyzed using repeated measures ANOVA. Results: At the completion of SAPS significant differences were found between groups in motivation for exercise (t=-3.24, p=.005), physical activity (t=-4.15, p<.001), total calorie intake (t=3.42, p=.002), calories from fat (t=-3.01, p=.005), intake of vegetables (t=-2.83, p=.008), and BMI (t=5.21, p<.001). Significant differences in BMI (t=4.13, p<.001) remained up to 3 months after SAPS completion. No significant differences was shown between groups in self-efficacy for exercise, either immediately after or 3 months after SAPS. Conclusion: The SAPS has the potential to improve motivation for exercise, health behavior, and BMI of BCS. However, special efforts are required to encourage participants to complete the intervention and maintain long-term effects for future trials.

Gas foil thrust bearings (GFTBs) support axial loads in oil-free, high speed rotating machinery using air or gas as a lubricant. Due to the inherent low viscosity of the lubricant, GFTBs often have super-laminar flows in the film region at operating conditions with high Reynolds numbers. This paper develops a mathematical model of a GFTB with turbulent flows and validates the model predictions against those from the literature. The pressure distribution, film thickness distribution, load carrying capacity, and power loss are predicted for both laminar and turbulent flow models and compared with each other. Predictions for an air lubricant show that the GFTB has high Reynolds numbers at the leading edge where the film thickness is large and relatively low Reynolds numbers at the trailing edge. The predicted load capacity and power loss for the turbulent flow model show little difference from those for the laminar flow model even at the highest speed of 100 krpm, because the Reynolds numbers are smaller than the critical Reynolds number. On the other hand, refrigerant (R-134a) lubricant, which has a higher density than air, had significant differences due to high Reynolds numbers in the film region, in particular, near the leading and outer edges. The predicted load capacity and power loss for the turbulent flow model are 2.1 and 2.3 times larger, respectively, than those for the laminar flow model, thus implying that the turbulent flow greatly affects the performance of the GFTB.
