Purpose: This study aimed to identify the prevalence of mild cognitive impairment (MCI) among a group of community-dwelling elderly and to determine if there were differences in general characteristics, activities of daily living (ADL), perceived health status (PHS) between the MCI group and group of elderly with normal cognitive function. Methods: This study utilized a descriptive survey design. Six hundred and five subjects over the age 65 were recruited from an S public health center, Seoul. Data were gathered through a variety of instruments: MoCA-K, K-MMSE, K-MBI, S-IADL, and PHS scale. Data were analyzed by SPSS/WIN 18.0 using descriptive statistics, Chi-Square test and t-test. Results: The prevalence of MCI among the subjects was 46.0%. Differences in IADL, PHS, age, education, sex, and residing with a spouse were statistically significant between groups. The MCI group had lower IADL, lower PHS, were older, and had lower educational levels than the group with normal cognitive function. Further, the MCI group was less likely to live with a spouse. Conclusion: It is suggested that MCI group should be targeted in developing and implementing nursing strategies to prevent dementia and improve the elderly cognitive function.

Objectives : The purpose of this study was to test stage model in Traumatic Brain Injury(TBI) patients. According to the stage model, attention deficits which is basic stage in information processing lead to memory disturbance and subsequently affect higher-order cognitive function such as memory, decision-making, abstract thinking, and judgement related to executive function. Therefore, it was hypothesized that attention affect recall(retrieval efficacy) related to executive function mostly relative to other cognitive function, in TBI patients with low executive function. Methods : Participants were referred to a TBI clinic and then was rated on K-WAIS and Executive Intelligence Test(EXIT). Participants were divided into two groups according to Executive IQ(EIQ) score, which of high function group(N=67) was more than 80(above low average) and of low function group(N=52) was under 80 (under borderline). To test the stage model, using hierarchical regression analysis, recall(retrieval efficacy) was regressed on 3 subscales(attention, verbal, visuospatial scale) after controlling for IQ according to each group. Furthermore, the mediation effect of attention between retrieval efficacy and verbal, visuospatial score was analyzed. Results : In the low function group, only attention area predicted significantly recall(retrieval efficacy), indicating that lower attention were related to lower EIQ after controlling for IQ. In the high function group, no area predicted significantly retrieval efficacy. In the low function group, verbal and visuospatial scale did not predicted significantly retrieval efficacy, indicating that there was no evidences supporting the mediation model. Conclusion : Only attention affect retrieval efficacy in TBI patients with low executive function. But, the mediation effect of attention between retrieval efficacy and verbal and visuospatial scale was not tested in the low function group. These results implied that stage model was tested partially. In treating cognitive deficit in TBI patients, it is necessary to develop cognitive rehabilitation program based on stage model. Furthermore, it is necessary to necessary to test mediation model in the future study.

This study identifies the moderating effects of cognition on the relationship between self-care confidence and self-care behavior in the diabetic elderly. The participants were 205 elderly subjects with diabetes, who visited a citizen health center located in D city, Korea. Data were collected from 20th April to 31st August 2015, and were analyzed by t-test and multiple regression. Our results reveal no significant differences between the depressive and non-depressive groups, when considering diabetes self-management confidence, knowledge, behavior and cognitive function. Cognitive function had a moderating effect in the relationship between self-care confidence and self-care behavior only in the depressed group. Our results indicate that it is therefore necessary to apply individual nursing intervention based on cognitive function and depression level, and to develop various programs for improving the cognitive function and depression amongst the diabetic elderly.

The study is conducted to identify the effects of the dementia preventive program on dementia knowledge, depression and cognitive function. A nonequivalent control group with pretest-posttest design was used on 61 elderly who were assigned to the experimental group 30 and control group 31. By using SPSS WIN 21.0 program, independent t-test was performed as analyzing method. The result of this study showed that average level of dementia knowledge was increased statistically (t=3.976, p<.001) at experimental group. Average level of cognitive function was increased statistically significant (t=3.048, p<.05) at experimental group. These findings confirmed that the dementia preventive program for preventing dementia was effective for improving dementia knowledge and cognitive function for elderly. Therefore, it is further encouraged to perform the dementia preventive program for preventing dementia within other Korean community in USA.

Purpose: The purpose of this study was to examine the effects of a smart-care services program for breast cancer survivors on cognitive function and physical health. Methods: A quasi-experimental control group pretest posttest design was used. Subjects were recruited in D city, and data were collected from July 2017 to February 2018. The experimental group (n=24) participated in the smart-care services program, whereas the control group (n=26) received conventional management. The smart-care services program consisted of addressing cognitive function problems arising from chemotherapy, diet, exercise, head/neck massage and self-monitoring using smartphone applications and smart bands. All participants underwent assessments at baseline, at 6 weeks, and at 12 weeks. Data were analyzed using descriptive statistics (frequency, percentage, mean and standard deviation), a chi-squared test, t-test, and repeated measures ANOVA. Results: After the smart-care services program, significant differences were found between the groups in cognitive function (F=18.91, p<.001) and sleep time (F=9.25, p<.001). No significant differences were found between the groups in caloric consumption after the program. Conclusion: The smart-care services program significantly improved the level of cognitive function and sleep time for breast cancer survivors. The use of this smart-care services program for breast cancer survivors might be an effective nursing intervention tool for improving cognitive function and health behaviors.

Purpose: The purpose of this study was to identify the prevalence of visual and hearing impairment and to investigate the effect of visual and hearing impairment on depression and cognitive function in community-dwelling Korean elderly. Methods: The study population consisted of a representative community sample of 4,028 persons aged 65 and older from the Korean Longitudinal Study of Aging 2008. Depression and cognitive function were measured by CES-D 10-item scale and K-MMSE. Visual and hearing impairment were measured by 5-Likert scale. Data were analyzed using Rao-Scott ${\chi}^2$-test, simple and multiple logistic regression. Results: The prevalence of visual and hearing impairment were 37.3% and 14.0%, respectively. Of the participants, the prevalence of depression was 58.4% and cognitive impairment was 50.6%. There were significant differences in depression and cognitive function according to visual and hearing impairment. Far vision and hearing impairment were predictors for both depression and cognitive impairment even after covariates had been adjusted. Conclusion: These data suggest that visual and hearing impairment in older adults may increase their probability of experiencing depression and cognitive impairment. Thus sensory impairment should be considered a risk factor for mental health and the cognitive function of elderly.

Objectives : The purpose of this study is to examine the effects of 3 day Forests healing programs for cognitive improvement, which consists of helpful contents of Korean medicine. Methods : This study examined the effects of forests healing for mild cognitive impairment patients, who visited a Korean medicine hospital neuropsychiatry clinic for outpatients. The Forests healing programs for cognitive improvement was run with 24 participants, in which 9 of them quit in the middle of the program, so excluded in data analysis. The Forests healing programs for cognitive improvement was consisted of 3 day helpful Korean medicine contents. The primary outcome measurement was a Computerized Neurocognitive Test (CNT), which measured the cognitive functions with computer programs. Results : The results of this study showed that CNT scores were not significantly changed after 3 day forests healing. General psychological states, including depression, anxiety, and anger, were also checked. Among them, depressive mood significantly improved. Quality of life (QOL) was also enhanced after 3 day program. These results indicate that the 3 day Forests healing programs for cognitive improvement was effective for depressive mood and QOL of mild cognitive impairment patients, but not enough for cognitive functions directly. Conclusions : The 3 day Forests healing programs for cognitive improvement were shown to be an effective intervention in improving some aspects of mild cognitive impairment patients, including depressive mood, and QOL. We suggest that repeated participation of this program can enhance cognitive function of mild cognitive impairment patients.

Purpose: This study was performed to investigate the influencing factors of cognitive function and depression in elderly. Method: From 3 provinces, 282 elders who resided in community and facilities completed structured questionnaires, including cognitive functions, depression, self-esteem, ADL, and IADL. Data were analyzed by applying ${\chi}^2$-test, ANOVA, partial correlation coefficient, and stepwise multiple regression analysis with SAS 8.12. Results: Community dwelling aged people showed higher scores in MMSE-K, self-esteem, ADL and IADL, and showed lower scores in depression than facility elders. MMSE-K was positively correlated in self-esteem, ADL, and personal cognition of health, except depression. Major factors that affect cognitive function of elderly were residual type, age, and IADL. In addition, major factors that affect depression of elderly were self-esteem, personal cognition of health, and marital status. Conclusions: Based on the results above, it is necessary to identify the status of cognition and depression in the elderly, and to develop nursing intervention programs, which improve cognitive function and reduce depression for aged, especially for the facility admitted aged.
