The purpose of this study was to evaluate the effect of exercise on cognitive function in the elderly through a systematic literature review and meta-analysis. For the study purpose, 14 studies were selected through a systematic process of using several databases and 11 studies were used to estimate the effect size of exercise on cognitive function. Meta-analysis was performed using a random effects model, and the effect size on cognitive function was calculated. The effect size for cognitive function of exercise intervention was Hedges' g=1.05 (95% CI: 0.61~1.50), indicating a large effect size. For heterogeneity, moderator analysis was performed using intervention, number of times per week, intervention duration, and cognitive function measurement. Cognitive function measurement was statistically significant, the other moderators did not significant difference. Results support that exercise has significant positive effects on cognitive function in elderly in korea. It also provided a basis that can be applied to exercise intervention design for cognitive function.

Purpose: This study aims to examine the influence of vitamin D and calcium on depression and cognitive function of the elderly living alone in a city. Methods: The participants were registered in eight senior centers in S city and they had lived alone. Data were collected between November 28, 2014 and March 7, 2015. A total of 155 people participated in data collection to measure the serum vitamin D, the serum calcium, depression, and cognitive function. The data were analyzed with t-test, ANOVA, Pearson's correlation and multiple regression analysis. Results: There were significant differences in depression according to gender and perceptions of health status. Depression correlated significantly with the serum calcium and perceptions of health status, and a stepwise regression analysis showed that the perceptions of health status were significant. There were significant differences in cognitive function according to education level and age. Cognitive function correlated significantly with the serum vitamin D and a stepwise regression analysis showed that education level and age were significant. Conclusion: Consequently, elderly people with poor perceptions of their health status need a depressive intervention program and those with a higher age and lower level of education need a cognitive function intervention program.

Purpose: The purpose of this study was to evaluate a cognitive behavioral anger management intervention in order to increase self-consciousness and decrease anger among Korean military men, Methods: A quasi-experimental design was used for this study. Ninety two soldiers were screened for unhealthy anger expression using a questionnaire. Among them, 26 soldiers who showed unhealthy anger expression were selected for this study. They were matched by rank and assigned to either a treatment or control group. The treatment group received the intervention three consecutive times, once a week and for 120 minutes per session. Participants were assessed before and after the intervention for anger (the State-Trait Anger Scale) and self-consciousness (Self-consciousness Scale). Data was analyzed using descriptive statistics, $x^2-test$, Mann-Whitney test, and Wilcox on signed rank test. Results: There was no statistically significant decrease in anger or increase in self-consciousness between the two groups following treatment. However, there was a significant increase in private self-consciousness in the treatment group after the intervention(p=.006). Conclusion: The cognitive behavioral anger management program improves private self-consciousness in soldiers. However, Additional research is needed to explore whether long-term intervention is more effective for anger control in the military setting. The findings from this study suggest that more attention should be given to mental health care for Korean soldiers.

Purpose: This study was to examine the effects of Dan Jeon Breathing on physical endurance, cognitive function, and depression in middle-aged women. Methods: This study employed a quasi-experimental with a nonequivalent control group pre-post test design. Participants were 59 middle-aged women and randomly assigned to the experimental or control group. Dan Jeon Breathing was carried out for 40 minutes per day, 3 times per week for 12 weeks between March 1 and July 31, 2010. Data were analyzed by Mann-Whitney U test and Wilcoxon signed ranked test for paired data. Results: After Dan Jeon Breathing intervention, the scores of physical endurance and depression of the experimental group were significantly higher than those of the control group. However, the scores of cognitive function between two groups were not significantly different. Conclusion: The Dan Jeon Breathing can be utilized as a nursing intervention for physical endurance and depression in middle-aged women. Also, a revised model of Dan Jeon Breathing is needed to be examined for cognitive function.

Healthcare providers in Korea are using conservative pharmacological treatment for Alzheimer's disease (AD) to delay the progress of the disease or to mitigate its behavioral and neurological symptoms. However, there is a growing need for interventions using practical non-pharmacologic treatment, as the effects of pharmacological treatments has faced limitations. This research provided a cognitive rehabilitation program to 3 AD patients and used a multiple baseline design across subjects to examine the effects. Performing reality orientation therapy (ROT) for 1 cycle (4 weeks) resulted in a slight increase in accuracy and responsiveness on an orientation task, mainly with patients with mild cases of AD. Also, in the sub-domain of the Korean-Mini Mental Status Examination performed to examine changes in cognitive ability, there were minimal changes in place orientation. In functional communication, however, there were no significant differences before and after the intervention. In conclusion, we found that ROT was an effective intervention for improving accuracy and responsiveness in the orientation of patients with mild cases of AD. In future studies, the effect of non-pharmacological interventions can be evaluated more reliably by examining the interaction effects of sample size, length of the intervention, outcome measurements, and pharmacological intervention.

Objectives : The purpose of this study was to develop a cognitive-behavioral intervention for college students at high risk for mental health and to investigate its effect on mental health outcomes. Methods : The program was developed to reduce depressive symptoms and adverse outcomes while promoting resilience and positive effects. It consisted of eight sessions in a small group format for eight weeks. Thirty subjects at high risk for mental health participated in the program. Outcomes on the depressive symptoms, resilience, satisfaction with life, negative affect, and positive affect were evaluated at pre-and post-intervention. Results : Depressive symptom scores reduced significantly post-intervention compared to pre-intervention (t=3.51, p=0.002). Resilience scores (t=-3.65, p=0.001) and satisfaction with life scores (t=-3.00, p=0.006) increased after intervention than pre-intervention. Positive affect scores decreased post-intervention (t=2.28, p=0.031). There was no significant difference between pre-and post-intervention negative affect scores (t=-0.94, p=0.356). Conclusions : Present study demonstrated that group-based cognitive-behavioral intervention could be helpful for college students at high risk for mental health to reduce mental health symptoms and improve healthy protective factors.

The purpose of this study was to classify the results of previous studies on the cognitive function improvement program of the elderly into the cognitive impairment group and the normal group to compare the effect sizes of the groups using meta - analysis. Among the previous studies on cognitive function improvement programs reported in Korea for the last five years, 86 were selected and the effect sizes were summarized using meta-analysis. As a result of the study, the overall average effect size showed a large effect size in both groups. The effect sizes of the intervention types were high for the cognitive impairment group, and the exercise and cognitive-based interventions were similar for the normal group. The gender effect size was higher for the women with cognitive impairment group, and higher for the combined case with normal group. The effect sizes according to group size were higher for 20 persons in cognitive impairment group and higher for 21~40 persons in normal group. The total number of sessions in both groups was higher than 32 times, The number of sessions per week was 3 times for the cognitive impairment group, 4 to 6 times for the normal group. The duration of activity was 55~60 minutes in cognitive impairment group and 70~180 minutes in normal group as the number of sessions and activity time increased the effect size was higher in normal group. This study will be meaningful in that it provided basic data necessary for future program development by comparing and analyzing the effect sizes of the cognitive function improvement program type and the activity factors between the cognitive impairment group and the normal group.

Purpose: During hospitalization, confusion occurs in 15~20% of older adults and persists in 5~10% of them. This study was designed to investigate effects of a five-day nursing intervention program designed to reduce confusion in hospitalized older adults. Subjects were inpatients over the age of 60 years old and were admitted in a surgical care unit. Methods: Data were collected from 111 patients. Subjects divided into one of two groups, 58 patients of the control group which received the usual nursing care; and 53 patients of the intervention group which received the usual nursing care plus nursing intervention program for reducing acute confusion. The Delirium Observation Screening Scale (DOS) and the Korean Mini-Mental Screening Examination (MMSE-K) were utilized. Results: 1) Acute delirium was significantly reduced in the intervention group compared to the control group ($x^2$=4.22, p=.034) as well as the duration of the delirious state was significantly shortened (F=56.62, p<.001). Cognitive function of the intervention group was improved (F=21.14, p<.001). Conclusion: The nursing intervention program reduced the incidence and duration of acute delirium of the elderly inpatients, as well as it helps them keep better cognitive function than the control group.
