The purpose of this study is to analyze whether a group reminiscence program is effective in improving self-esteem and reducing depression in the elderly. The subjects of the study were 20 men and women aged 65 or older who used a senior welfare center located in N City. They were randomly assigned to the experimental group (n=10) and control group (n=10). Self-esteem and Korean Depression Scale (GDS-K) were used as measurement tools to verify the effectiveness of the program. The experimental group conducted a total of 10 sessions, once a week, for 80 minutes each. A group counseling program was implemented for the experimental group, and no measures were taken for the control group during the same period. To verify the effectiveness of this program, the SPSS 21.0 statistical program was used to calculate the mean and standard deviation of the pre- and post-tests for each group and conduct an independent samples t-test. As a result of the study, the experimental group that implemented the program significantly improved self-esteem and significantly decreased depression compared to the control group. Based on these results, the significance and limitations of the study were discussed.

This study was conducted to confirm the level of stress and infection prevention behavior of nursing college freshman during the COVID-19 pandemic. 119 nursing college freshmen who took remote classes because face-to-face classes were not possible due to the COVID-19 pandemic. The collected data were analyzed by descriptive statistics, Independent t-test, one-way ANOVA, and Pearson's correlation coefficient using SPSS WIN/PC 26.0 statistics program. As a result of this study, the sensitivity to stress was significantly higher when the attitude towards college life was passive (F=5.92, p=.004), and when people perceived themselves as healthy, their stress was significantly lower (t=-2.22, p=.029). In addition, those who responded that they were very uncomfortable due to activity restrictions due to COVID-19 had a significantly higher level of infection prevention behavior than those who responded that they did not feel any discomfort (F=3.51, p=.018). In a pandemic environment such as COVID-19, efforts to promote a positive attitude and awareness of health conditions are needed to reduce the stress of college freshmen and increase infection prevention behavior.

We test the hypothesis that the gradual diffusion of information across asset markets leads to cross-asset return predictability in Korea. And, the aim of this paper is related to forecast the stock market, business cycle index and industrial production by various indicators of economic activities in Korea. For this, our paper sets models and focuses on empirical test. The stock market on this month correlate with industries in Korea. The stock market doesn't lead to industries. The industries and macroeconomic variables have high correlation. We test that gradual diffusion of industrial information will predict stock market in Korea. For this, we analysis on possibility of Granger cause by VAR models between industries and stock market. As a result, 21 portfolios cause to Kospi statistically significance at 5%. Especially, the Beverage portfolio has bilateral Granger causality to Kospi. In case of Internet and Cosmetics portfolio, Kospi has unilateral Granger causality to it. The predictability of specific industries has a relation to Macroeconomic variables. What industrial portfolios predict to Business Coincidence Index? The only 6 industrial portfolios of 36 portfolios have a statistically significance at 10%. And, 9 portfolios have a statistically significance at 5%.

Objectives : This study aimed to investigate the psychosocial characteristics of functional gastrointestinal disorder (FGID) in patients with psychiatric disorders. Methods : This study was conducted with 144 outpatients visiting the psychiatric clinic at a university hospital. FGIDs were screened according to the Rome III questionnaire-Korean version. Demographic factors were investigated, and psychosocial factors were evaluated using the Hospital Anxiety Depression Scale, Patient Health Questionnaire-15, Childhood Trauma Questionnaire-Korean, and State-Trait Anger Expression Inventory. Chisquared test and student's t-test were used as statistical analysis methods. Results : There were differences in education level between two groups divided according to FGID status (${\chi}^2=10.139$, p=0.017). Comparing the psychiatric disorder by FGID group, irritable bowel syndrome (IBS) group showed significant differences (${\chi}^2=11.408$, p=0.022). According to FGID status, IBS group showed significant differences for anxiety (t=-3.106, p=0.002), depressive symptom (t=-2.105, p=0.037), somatic symptom (t=-3.565, p<0.001), trait anger (t=-3.683, p<0.001), anger-in (t=-2.463, p=0.015), and anger-out (t=-2.355, p=0.020). Functional dyspepsia group showed significant differences for anxiety (t=-4.893, p<0.001), depressive symptom (t=-3.459, p<0.001), somatic symptom (t=-7.906, p<0.001), trait-anger (t=-4.148, p<0.001), state-anger (t=-2.181, p=0.031), anger-in (t=-2.684, p=0.008), and anger-out (t=-3.005, p=0.003). Nonerosive reflux disease group showed significant differences for anxiety (t=-4.286, p<0.001), depressive symptom (t=-3.402, p<0.001), somatic symptom (t=-7.162, p<0.001), trait anger (t=-2.994, p=0.003), state anger (t=-2.259, p=0.025), anger-in (t=-2.772, p=0.006), and anger-out (t=-2.958, p=0.004). Conclusions : Patients with psychiatric disorders had a high prevalence of FGID, and various psychosocial factors contributed to such differences. Therefore, the psychiatric approach can offer better understandings and treatments to patients with FGID.

This study was conducted to investigate the effects of child nursing simulation using standardized patient on nursing student's anxiety, self-efficacy, and critical thinking disposition. A one group pre test-post test design was used. The subjects of the study were 62 students in the nursing department and 4th year students at the university in C city. The hospitalized child nursing simulation was conducted for approximately 3.5 hours, including 60 minutes of pre-study and orientation, 60-80 minutes of hands-on scenarios, and 30 minutes of reflection diary writing and debriefing. The data collection was conducted from March to December 2016. Statistical analyses of the collected data were conducted, including t-tests, Pearson's correlation coefficient, and Cronbach's ${\alpha}$. Analyses were conducted using SPSS 21.0. The results of the study showed that anxiety (p <.001) was significantly lower and self-efficacy (p<.001) and critical thinking disposition (p<.001) were higher. Therefore, we propose that various scenarios for simulation practice that utilize standardized patients to enhance core nursing abilities be developed.

Since Gamma Knife(R) radiosurgery(GKRS) is based on a single-fraction high dose treatment strategy, independent verification for the results of Leksell GammaPlan(R) (LGP) is an important procedure in assuring patient safety and minimizing the risk of treatment errors. Several verification methods have been developed and reported previously. Thus these methods were tested statistically and tried on Leksell Gamma Knife(LGK) target treatments through the embodiment of the previously proposed algorithms(PPA). The purpose of this study was to apply and evaluate the accuracy of verification methods for LGK target treatments using PPA. In the study 10 patients with intracranial lesion treated by GKRS were included. We compared the data from PPA and LGP in terms of maximum dose, arbitrary point dose, and treatment time at the isocenter locations. All data were analyzed by Paired t-test, which is statistical method used to compare two different measurement techniques. No statistical significance in maximal dose at 10 cases was observed between PPA and LGP. Differences in average maximal dose ranged from -0.53 Gy to 3.71 Gy. The arbitrary point dose calculated by PPA and LGP was not statistically significant too. But we found out the statistical difference with p=0.021 between TMR and LGP for treatment time at the isocenter locations. PPA can be incorporated as part of a routine quality assurance(QA) procedure to minimize the chance of a wrong overdose. Statistical analyses demonstrated that PPA was in excellent agreement with LGP when considering the maximal dose and the arbitrary point dose for the best plan of GKRS. Due to the easy applicability we hope PPA can be widely used.
