Purpose: This study was done to examine good death awareness, attitudes toward advance directives (ADs), and preference for care near the end-of-life (PCEOL) of hospitalized elders in long-term care hospitals. Relevant characteristics were investigated as well as correlation of the variables. Methods: This descriptive research study involved 161 hospitalized elderly patients in long-term care hospitals. A self-report questionnaire was used to measure Good Death Scale, ADs Survey, PCEOL Scale, and general characteristics. Collected data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation with SPSS/WIN 23.0. Results: In terms of good death awareness, a significant difference was observed; in according to age (F=3.35, p=.037), payer of treatment costs (F=3.98, p=.021), mobility (F=3.97, p=.021), heard discussion about ADs (t=-3.89, p<.001), and willing to complete ADs (t=2.12, p=.036). As far as attitudes toward ADs, the participants presented significant difference depending on religion (t=2.38, p=.018), average monthly income (F=3.91, p=.022), duration of hospital admission (F=5.33, p=.006), person to discuss ADs (t=-2.76, p=.006). On PCEOL, there was a significant difference, depending on religion (t=-3.59, p<.001) and perceived health status (F=3.93, p=.022). Finally, as for how the variables were related to each other, good death awareness and attitudes toward ADs had a weak positive correlation with PCEOL. Conclusion: To help seniors staying in nursing homes face a good death and enjoy autonomy, there should be educational and support systems that reflect each individual's sociodemographic characteristics so that the seniors can choose what kind of care they want to receive near the end-of-life.

Purpose: This study investigated the effects of prenatal education characteristics, pandemic-related pregnancy stress, and health behaviors during pregnancy on prenatal depression in pregnant women during the coronavirus disease 2019 (COVID-19) pandemic. Methods: The participants were 180 pregnant Korean women, recruited from internet communities for pregnancy preparation, childbirth, and childcare, from July 5 to 15, 2022. The collected data were analyzed using the t-test, analysis of variance, the Mann-Whitney U-test, the Kruskal-Wallis test, and multiple regression analysis. Results: The scores for pandemic-related pregnancy stress (24.50±6.37) and health behaviors during pregnancy (67.07±9.20) were high. Nearly half of the participants (n=89, 49.4%) presented with prenatal depression, with scores of 10 or greater. Prenatal depression had a positive correlation with gestational age (r=.18, p=.019) and pandemic-related pregnancy stress (r=.27, p<.001), and a negative correlation with health behaviors during pregnancy (r=-.42, p<.001). The factors associated with prenatal depression were pandemic-related pregnancy stress (t=4.70, p<.001), marital satisfaction (dissatisfied) (t=3.66, p<.001), pregnancy healthcare practice behaviors (t=-3.31, p=.001), family type (weekend couple) (t=2.84, p=.005), and gestational age (t=2.32, p=.022). The explanatory power of these variables was 38.2%. Conclusion: Since participants had a high level of prenatal depression during the pandemic, and infectious diseases such as COVID-19 may recur, strategies should be developed to improve pregnant women's mental health with consideration of the unique variables that are relevant in a pandemic. It is also necessary to develop efficient online prenatal education programs that can be implemented even in special circumstances such as social distancing, and to evaluate their effectiveness.

The paper discusses the problem of controlling systems with a very high number of input variables effectively by fuzzy If . . . then rules. The basic idea is the partition of the state space into domains, which step can be done even iteratively several times, and every domain has its own sub rule base referring to a considerably lower number of variables than the original space. In this manner the number of necessary rules is drastically reduced and time complexity of the control algorithm remains acceptable.

Purpose: The purpose of this study was to investigate the effect of dehydration from preoperative fasting on postoperative nausea and vomiting in patients who underwent gynecologic surgeries. Methods: Study design was a prospective descriptive study. A total of 75 patients in a university hospital were selected. Data were collected from March 17 to May 16, 2014 using self-report questionnaires and clinical electronic chart. Results: Factors influencing the development of postoperative nausea and vomiting were type of surgery (t=3.44, p=.001), use of PCA (t=-2.16, p=.034), and preoperative dehydration level (t=5.93, p<.001), and these variables accounted for 51.7% of postoperative nausea and vomiting. Among these variables, preoperative dehydration amount (${\beta}=.56$) showed the largest influence in the difference in postoperative nausea and vomiting. Conclusion: Reducing dehydration during preoperative fasting can prevent occurrence of postoperative nausea and vomiting. Development of a clinical guideline is necessary to give directions for the prevention of dehydration during preoperative fasting and to ensure the proper duration of fasting according to patient characteristics, type of surgery and time of surgery.

Purpose: This study was conducted to investigate the correlation between uncertainty and depression in hospitalized children's mothers. Methods: The subjects were 175 mothers of children who were hospitalized in pediatric unit. A self report questionnaires were used to measure the variables. Variables were uncertainty and depression. In data analysis, SPSSWIN 20.0 program was utilized for descriptive statistics, ANOVA, Pearson's correlation coefficients and multiple regression. Results: Reliability of instruments were found cronbach's alpha=.85~.86. Uncertainty correlated positively with depression(r=.422, p<.010). There were significant differences in depression according to birth order(F=6.58, p=.002), mothers' age(F=6.57, p=.002), education level(F=3.97, p=.021) and mothers' job(t=19.18, p<.001), monthly income(F=4.234, p=.006) and family type(t=7.49, p=.007). In multiple regression, uncertainty, mothers' job and family type were significant predictors of depression in hospitalized children's mothers explaining 30.9%. Conclusions: Uncertainty and depression were significant variables in hospitalized children's mothers. The strategy of nursing intervention which decrease depression in mothers must be developed by decreasing level of uncertainty in mothers of hospitalized children.

The purpose of this study was to find out whether home environmental variables had a greater effect on adolescents' violence against parents. The results of self-reporting questionnaires are as follows ; The victims of violence are mainly mothers. The socio-economic status didn't influence on the degree of violence against parents. The adolescents of the extreme family type used more serious violent behavior. The higher the degree of observed and experienced violence is, the higher the degree of violence against parents. Also, the higher the degree of home education is, the lower the degree of violence against parents. Of all variables, the observed violence and structure-environmental variables account for 37.6% of adolescents' violence against parents. The results of in-depth interview showed that birth-order didn't affect violence against parents. The victims of violence were mainly stepmothers and stepfathers. These parents' educational attitudes were disagreement in parents, seriously inflicted corporal punishment and were indifferent to adolescent. Also, interviewed adolescents were observed and experienced violence in home and used violence against others.

This study was conducted to examine factors influencing mental health of middle-aged adults(N=203) in relation to sociodemographic variables, health behaviors, and social support. The survey with questionnaire was carried out for the subjects of the residents in two communities of a local city located in Gangwon-do, Korea from September 3 to 15, 2003. Data analysis procedure included stepwise multiple regression using mental health as the dependent variable, and sociodemographic variables, health behaviors, and social support as independent variables. There were significant differences in the mental health by birth place(t=-1.67, p<0.10), religion (t=2.27, p<0.05) and subjective economic status(F=2.29, p<0.10). Mental health showed significant positive correlations with both health behavior (r=0.462, p<0.001) and social support (r=0.142, p<0.05). Stepwise multiple regression analysis for mental health revealed that the most powerful predictor was health behavior(β=0.453, p<0.001). Health behavior and religion explained 24％ of the variance. The results suggest the necessity of a intervention that considers the health behaviors should be included in middle-aged adults so as to promote mental health.

The study aims to assess the acceptance of social commerce and participate in social commerce amongst Omani people. The questions of the survey Instrument were prepared in English later converted into Arabic. The survey instrument was having two parts; the first part sought the demographic information like age, gender, education, occupation etc. The second part of the instrument was related to the variables, which was in 5-point Likert scale, where 5 means strongly agree while 1 meaning strongly disagree. The data was collected using online and offline surveys, making the number of the valid responses to 478. A conceptual model was developed using the following variables. The selected variables such as "Familiarity" (F), "Trust" (T), "Perceived usefulness" (PU), "Perceived ease of use" (PEU), "Intention to Purchase" (IP). The hypothesis was tested using structural equation modelling. The results indicate that all six hypotheses were supported. The F, T and PEU, and PU was found to be positive and significant related to intention to purchase (p-value 0.003, 0.001, 0.000. & 0.007). Amongst the four, p value of F was found to be the lowest and PU was found to be the highest. This indicate F was strong indicator of IP as compared to others. PUE relates to PU, and F was related to IP.
