Purpose: This study aimed to identify the relationships among attitudes towards death, perceptions of hospice care, and hospice care needs as perceived by family members of patients in the intensive care unit (ICU). Methods: This study used a descriptive correlational method. A structured questionnaire was used to collect data from 114 participating families in the ICU at Dong-A University Hospital, from October 10 to November 1, 2019. The data were analyzed in terms of frequency, percentage, and mean and standard deviation. The t-test, one-way analysis of variance, and Pearson correlation coefficients were also conducted. Results: Perceptions of hospice care showed significant differences according to age (F=3.06, P=0.031) and marital status (t=3.55, P=0.001). However, no significant differences in attitudes towards death or hospice care needs were found. A significant positive correlation was found between perceptions of hospice care and hospice care needs (r=0.49, P<0.001). Conclusion: In order for families to recognize the need for hospice care and to receive high-quality palliative care at the appropriate time, it is necessary to increase public awareness of hospice care through various educational and awareness-raising efforts, thereby providing opportunities for families of terminally ill patients to request hospice care.

Purpose: The purpose of this study was to identify factors influencing prevention behaviors for particulate matter exposure in young adults. Methods: A convenience sample of 330 young adults was recruited from the community. Data were collected using a structured questionnaire and analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression analysis with the SPSS/WIN 26.0 program. Results: The factors affecting prevention behaviors of particulate matter exposure were self-efficacy (β=.54 p<.001), subjective norm (β=.18, p<.001) and using the air purifier (β=.-17, p<.001). These variables had a 46% variance to explain prevention behaviors for particulate matter exposure. Conclusion: Findings showed that 'self-efficacy' and 'subjective norm' were important factors influencing prevention behaviors of particulate matter exposure in young adults. Thus, we need to consider the positive impact of prevention behaviors of particulate matter exposure and increase the chances of prevention behaviors of particulate matter exposure program for young adults.

This research aims to explore factors influencing creativity among the employees of nanotechnology companies. Further, this survey aimed to investigate the role of psychological capital (PS), job satisfaction (JS) and corporate social responsibility (CSR) as sources to foster creativity. Participants included 375 employees of nanotechnology companies in China. Sequential mediation analysis revealed that creativity was significantly influenced by psychological capital, job satisfaction and corporate social responsibility. Furthermore, not only psychological capital, job satisfaction and corporate social responsibility were directly and indirectly related to creativity but also explained 67.35% variance of it. It seems that having more psychological resources, more well-being and good feelings concerning performance in the workspace and the efforts of companies to improve employee welfare are among the most important factors in increasing employee creativity. Our findings can help companies, especially nontechnology companies, in focusing on factors fostering the creativity of employees, because creativity enhances and promotes the performance and success of companies.

Purpose: This study examined the perceived quality of life of families of individuals with developmental disabilities who regularly participate in physical activities. It also explored differences in the quality of family life based on variables such as family relationships, family income, gender, disability type, and age. Methods: A survey was administered to 69 family members of individuals with developmental disabilities who regularly participate in physical activities. The collected data were analyzed using descriptive statistics, independent samples t-test, and one-way analysis of variance. Results: The average overall quality of life for families of individuals with developmental disabilities who participate in continuous physical activities was 3.49. After analyzing each subtype, psychological health was found to be 3.91, the burden for people with developmental disabilities was 2.75, community participation was 3.76, cohesion was 3.83, and openness was 3.49. No statistically significant differences were found in family relationships or family classes, disability type, age, or gender of the individuals with developmental disabilities across the variables. Conclusion: When planning service development and support to improve the quality of life for families of individuals with developmental disabilities, it is necessary to develop systematic programs at the family level rather than providing support based on various variables.

This paper is intended to determine the optimal processing parameters applied to the dyeing procedure so that the desired color strength of a raw fabric can be achieved. Moreover, the processing parameters are also used for constructing a system to predict the fabric quality. The fabric selected is the nylon and Lycra blend. The dyestuff used for dyeing is acid dyestuff and the dyeing method is one-bath-two-section. The Taguchi quality method is applied for parameter design. The analysis of variance (ANOVA) is applied to arrange the optimal condition, significant factors and the percentage contributions. In the experiment, according to the target value, a confirmation experiment is conducted to evaluate the reliability. Furthermore, the genetic algorithm (GA) is combined with the back propagation neural network (BPNN) in order to establish the forecasting system for searching the best connecting weights of BPNN. It can be shown that this combination not only enhances the efficiency of the learning algorithm, but also decreases the dependency of the initial condition during the network training. Most of all, the robustness of the learning algorithm will be increased and the quality characteristic of fabric will be precisely predicted.

National-wide and/or large scale sample surveys generally use complex sample design. Traditional Pearson chi-square test is not appropriate for the categorical complex sample data. Rao-Scott suggested an adjustment method for Pearson chi-square test, which uses the average of eigenvalues of design matrix of cell probabilities. This study is to compare the efficiency of Rao-Scott first order adjusted test to Wald test for homogeneity between two populations using 2009 Gyeongnam regional education offices's customer satisfaction survey (2009 GREOCSS) data. The 2009 GREOCSS data were collected based on stratified three-stage cluster sampling with probability proportional to size. The empirical results show that the Rao-Scott adjusted test statistic using only the variances of cell probabilities is very close to the Wald test statistic, which uses the covariance matrix of cell probabilities, under the 2009 GREOCSS data based. However it is necessary to be cautious to use the Rao-Scott first order adjusted test statistic in the place of Wald test because its efficiency is decreasing as the relative variance of eigenvalues of the design matrix of cell probabilities is increasing, specially more when the number of degrees of freedom is small.

Purpose: This study was done to develop a prediction model for postpartum depression by verifying the mediation effect of antepartum depression. A hypothesized model was developed based on literature reviews and predictors of postpartum depression by Beck. Methods: Data were collected from 186 pregnant women who had a gestation period of more than 32 weeks and were patients at a maternity hospital, two obstetrics and gynecology specialized hospitals, or the outpatient clinic of K medical center. Data were analysed with descriptive statistics, correlation and exploratory factor analysis using the SPSS/WIN 18.0 and AMOS 18.0 programs. Results: The final modified model had good fit indices. Parenting stress, antepartum depression and postpartum family support had statistically significant effects on postpartum depression, and defined 74.7% of total explained variance of postpartum depression. Antepartum depression had significant mediation effects on postpartum depression from stress in pregnancy and self-esteem. Conclusion: The results of this study suggest that it is important to develop nursing interventions including strategies to reduce parenting stress and improve postpartum family support in order to prevent postpartum depression. Especially, it is necessary to detect and treat antepartum depression early to prevent postpartum depression as antepartum depression can affect postpartum depression by mediating antepartum factors.

Purpose: The purpose of this study was to identify factors influencing depression in breast cancer patients. Method: A descriptive correlational study design was used. A convenience sample of 155 subjects was recruited from the outpatient for breast cancer patients at one hospital in Gyeonggi, South Korea. Body image was measured with the category of "Body image" from the EORTC QLQ-BR23(European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Breast cancer version) and sexual function was measured with category of "sexual function" from it. Depression was measured with Korean version of Beck Depression Inventory(BDI). Results: The mean score of body image was relatively low(M = 54.44, SD = 30.92), of sexual function was low (M = 24.82, SD = 22.50), and of depression was relatively low(M =14.90, SD = 8.00). Depression had a significant relationship with body image(r = -.363, p = <.001), however, there was no significant relationship between depression and sexual function(r = -.137, p = .103). In the regression analysis, depression was found to be influenced significantly by monthly income and body image, these variables explained 28.8% of the variance in depression(F = 4.662. p = <.001). Conclusion: It suggests that nurses need to take into consideration body image and economic status in management depression in breast cancer survivors.

Purpose: The study was performed to identify exercise self-efficacy, depression, and stress by the stage of change in exercise behavior in middle aged women. Method: The subjects consisted of 317 women residing in B city by convenience sampling. The collected data was analyzed by the SPSS/WIN program. Result: The subjects were distributed in each stage of exercise behavior change: There were 53 subjects in the pre-contemplation stage, 86 subjects in the contemplation stage, 88 subjects in the preparation stage, 51 subjects in the action stage and 39 subjects in the maintenance stage. Analysis of variance showed that exercise self-efficacy (F=39.9, p<.001), depression (F=5.58, p<.001), and stress (F=6.33, p<.001) were significantly associated with the stages of exercise behavior change. There was a significant negative correlation between the stage of change and depression, and the stage of change and stress, but a significant positive correlation between the stage of change and self- efficacy, depression and stress. Conclusion: This study identified that exercise self-efficacy, depression and stress were significant variables to explain a possible relationship with exercise stages of middle aged women. This study provides new information to influence the development of better health promotion and exercise intervention for middle aged women in the community.

Purpose: The purpose of this study was to investigate the level of self management of patients with poorly controlled type 2 diabetes, and to investigate the factors influencing self management. Methods: The subjects consisted of 117 diabetes patients who visited the outpatient department of a university hospital from March to August 2008. Data were collected by asking the subjects to answer a 54-item questionnaire and were analyzed using the SPSS/WIN 14.0 program. Results: The total mean score of the patients in self -management was 4.38 out of 7. Medication adherence obtained the highest score under self-management, and the self-monitoring of blood glucose obtained the lowest score. Family support, self-efficacy, severity, and depression were found to be significantly correlated with self-management. In stepwise multiple regression analysis a total of 44.5% of the variance in self management was accounted for by family support, self-efficacy, severity, and depression. Conclusion: Therefore, a diabetic intervention program should be designed and provided for increasing family support, self efficacy, and severity and for reducing depression of patients with poorly controlled type 2 diabetes.
