This study evaluates the social value orientation, well-being of the elderly and care needs of elderly that elderly care services are identified and seeks future service development directions through a desire survey. As of October 2019, 1,501 elderly living alone who used basic care services for the single elderly households for more than 3 months were sampled, and frequency analysis, technical statistical analysis, t-test, and variance analysis were conducted. The survey found that social value orientation averages 90.93, and the sense of well-being of the elderly is 71.29 points. As a result of the analysis of variance and post-hoc analysis, the well-being of the elderly was statistically significant in groups well aware of their social value orientation. In addition, key words such as "loneliness", "lonely Death", and "safety" were derived for concerns that may arise when the service is discontinued. Based on the results of this study, it could be used as basic data to explore the development direction of the new "elderly care services" and to establish a care system for senior citizens in preparation.

Purpose: This study was to investigate the belief in evidence-based practice, awareness of importance and performance of intravenous infusion and pressure ulcer evidence-based practice guidelines among nurses in a tertiary general hospital. Methods: The subjects of this study were 217 nurses working in a tertiary general hospital. Data collection was performed between February 11 and February 25, 2022. Data analysis was conducted descriptive statistics, t-test, hierarchical regression analysis, and Importance-Performance Analysis. Results: The mean score of belief for evidence-based practice among novice nurses was 3.34 out of 5, while preceptor nurses scored a mean of 3.41 out of 5. There was no significant difference in belief scores between novice nurses and preceptor nurses (t=-1.21, p=.227). The factors influencing the performance of evidence-based practice guidelines for intravenous infusion were belief in evidence-based practice (β=.14, p=.009) and importance of intravenous infusion (β=.51, p<.001), and the factors influencing the performance of evidence-based practice guidelines for pressure ulcer were belief in evidence-based practice (β=.15, p=.002) and importance of pressure ulcer (β=.65, p<.001). Importance-Performance Analysis of the evidence-based practice guidelines of two groups were used to identify common and different items. Conclusion: To improve the performance of evidence-based practice guidelines, it is necessary to enhance the evidence-based practice belief and importance of evidence-based practice guidelines. In particular, evidence-based practice should be provided to improve nursing quality through education on items of low-importance and low-performance and items of high-importance but low-performance guidelines identified through Importance-Performance Analysis.

This study was aimed at the married immigrant women and was attempted to provide the basic data of the nursing practice useful in identifying the relationship aspects and the influence of resilience factor and promoting the family adaptation. This study was conducted for the married immigrant women who were located in urban-rural complex area around Daejeon city and in Chungnam region, and the multi-cultural families supporting program of community welfare halls among those who had resided over 1 year in Korea. The data was collected from Feb, 2012 to July, 2012 and in the end, 216 questionnaires were made the subjects of data analysis. For the collected data, frequency analysis, percentage, ANOVA, t-test and correlation analysis were conducted using SPSS, LISREL. The overall index of hypothesis model showed a good congruence like ${\chi}^2$ = .06 (p= .812), df=1, ${\chi}^2$(df)=.06, GFI=1.0, AGFI= 1.0, SRMR=.002, NFI= 1.0, NNFI=1.0, RMSEA=0.000, CN=266. Looking at the results of hypothesis testing suggested by the model, the variables which affected the family adaptation were family stress and parenting stress, while social support, family hardness, problem solving communication, and problem solving coping didn't affect the family adaptation. It is considered that based on the results of this study, nursing intervention which helps the family adaptation of the married immigrant women who are in a crisis situation must be done with a program which can help them have a positive view on the stress situation and reduce the stress happening in the family relationship and parenting.

The purpose of this case-control study was done to examine the relationship among the cerebral infarction, blood lipids and homocysteine. We compared the components of blood lipids and homocysteine between cerebral infarction patients group (n=127) and controls group (n=158). We performed Pearson's chi-square test and Student's t-test for univariate analysis, Binary logistic regression for multivariate analysis to evaluate risk factors of cerebral infarction and Pearson's correlation analysis to investigate correlation between blood lipids and homocysteine. The results were as follows. The blood levels of High density lipoprotein cholesterol(HDL-Chol) and Low density lipoprotein cholesterol (LDL-Chol) were significantly lower in patients group, while age, the blood levels of Triglyceride(TG) and homocysteine were significantly higher in patients group. Hypertension had a 4.62 odds ratio, $TG{\geq}150\;mg/d{\ell}$ had a 2.33 odds ratio, HDL-Chol ${\leq}40\;mg/d{\ell}$ had a 6.85 odds ratio, but sex, DM, T-Chol, LDL-Chol had no direct relationship with odds ratio(non significant). In addition, among T-Chol and TG , HDL-Chol, LDL-Chol, they had positive correlation each other. Between TG and HDL-Chol had negative correlation each other. Homocysteine was not correlated with blood lipids adjusted for age and sex. These results suggest that low HDL-Chol and high TG may be risk factor of cerebral infarction. The correlation between homocysteine and blood lipids was not proven.y urther reserch on the subject is needed.

Background: Normalized cerebral blood volume (nCBV) can be measured using manual or semiautomatic segmentation method. However, the difference in diagnostic performance on brain tumor differentiation between differently measured nCBV has not been evaluated. Purpose: To compare the diagnostic performance of manually obtained nCBV to that of semiautomatically obtained nCBV on glioblastoma (GBM) and primary central nervous system lymphoma (PCNSL) differentiation. Materials and Methods: Histopathologically confirmed forty GBM and eleven PCNSL patients underwent 3T MR imaging with dynamic susceptibility contrast-enhanced perfusion MR imaging before any treatment or biopsy. Based on the contrast-enhanced T1-weighted imaging, the mean nCBV (mCBV) was measured using the manual method (manual mCBV), random regions of interest (ROIs) placement by the observer, or the semiautomatic segmentation method (semiautomatic mCBV). The volume of enhancing portion of the tumor was also measured during semiautomatic segmentation process. T-test, ROC curve analysis, Fisher's exact test and multivariate regression analysis were performed to compare the value and evaluate the diagnostic performance of each parameter. Results: GBM showed a higher enhancing volume (P = 0.0307), a higher manual mCBV (P = 0.018) and a higher semiautomatic mCBV (P = 0.0111) than that of the PCNSL. Semiautomatic mCBV had the highest value (0.815) for the area under the curve (AUC), however, the AUCs of the three parameters were not significantly different from each other. The semiautomatic mCBV was the best independent predictor for the GBM and PCNSL differential diagnosis according to the stepwise multiple regression analysis. Conclusion: We found that the semiautomatic mCBV could be a better predictor than the manual mCBV for the GBM and PCNSL differentiation. We believe that the semiautomatic segmentation method can contribute to the advancement of perfusion based brain tumor evaluation.

This study was performed to identify the association between the menarche experience and mental health in middle school girls aged 14. The subjects were selected using data from the 8th Korean Youth Risk Behavior Web-based Survey (KYRBWS-V), which included 5,991 girls in 1st grade of middle school. Data were analyzed using the PASW 18.0 program for frequency analysis, t-test, chi square and logistic regression analysis. As to results, we found 4,473 girls who had experienced menarche (mean age, 12.8 0.9 years) and 1,518 girls hadn't experienced menarche. In the logistic regression analysis between the menarche experience and mental health behaviors, the odds ratio (OR) [95% confidence interval (CI)] for perceived stress (OR=1.39, 1.20-1.62, p<0.001), perceived depression (OR=1.25, 1.10-1.42, p<0.05), suicide thinking (6OR=1.60, 1.38-1.87, <0.001), suicide planning (OR=1.66, 1.33-2.81, p<0.001) and suicide trial (OR=1.42, 1.09-1.86, p<0.05) were higher in the menarche experience group than in the menarche non-experience group. Our results indicate, a viable association between the menarche experience and mental health in the 1st grade of middle school girls, and suggests that the menarche experience is an important factor influencing adolescent girls' mental health.

The purpose of this study was to evaluate the relationship between bone mineral density (BMD) and body composition (BC) or backmuscle strength (BS). Sixty-one participants were measured by BMD using ultrasound bone densitometry and Inbody for BC (i.e., SLM=Soft lean mass, SMM=Skeletal muscle mass, FS=Fitness score. et al.), BS after self-questionnaire for life cycle. This study was performed after approving Institutional Review Board and obtaining the informed concent from all participants. Participants was divided into two group by BMD T-score; $T-score{\geq}-1.0$, T-score<-1.0. Statistical analysis was performed by using SPSS ver. 22.0(USA), Spearma test for correlation between BMD and BC or BS. BMD or SLM, BS was increased with increasing physical activity or body mass index. SMM or SMM, FS of BMD $T-score{\geq}-1.0$ group was higher than that of T-score <-1.0 group as well as BS(p>0.05). BMD T-score was correlated positively with SLM(r= 0.424) or SMM(r= 0.431) in men, as well as in women(p<0.05). BS was correlated positively with SLM or SMM, FS. BS was significantly positive correlated with BMD in women group (r= 0.591, p= 0.001), but not in men group. We concluded that BMD is the relationship with SLM or SMM, as well as BS in women.
