Background: Depression and cognitive function have a positive effect on the improvement of quality of life and extension of lifespan in the elderly. In addition, it appears as a major factor influencing oral health status. Therefore, this study looked at the relationship between the Geriatric Oral Health Assessment Index (GOHAI), depression, and cognitive function in the elderly using the Korea Longitudinal Study of Aging. Methods: In this study, 4,535 elderly people aged 65 years and over were targeted using the 7th data of the 2018 Korea Longitudinal Study of Aging. A t-test and ANOVA analysis were performed to compare GOHAI, depression, and cognitive function by group. In addition, hierarchical multiple linear regression was performed to understand the effect of the elderly's perceived depression scale and cognitive ability on GOHAI. Results: As a result of adding the depression scale and cognitive function variables to Model 2, the explanatory power was 22%. Educational level, marital status, private health insurance subscription, average monthly allowance, subjective health status, use of dentures, smoking status, economic activity, depression scale, and cognitive function were found to have significant influence (p<0.05). In addition, when controlled and viewed with all factors, depression and cognitive function were found to have an effect on oral health-related quality of life. Conclusion: The findings indicate that depression and cognitive function are associated with oral health-related quality of life in the Korean elderly. As the age increases, the quality of life declines due to depression and cognitive function problems, in addition to oral discomfort, eating disorders, and physical discomfort.

본 연구는 공감 능력이 사회 정의 실천에 미치는 영향을 사회 인지적 관점에서 알아보고자 하였다. 구체적으로 인지적 공감과 정서적 공감이 사회 정의 자기 효능감, 사회 정의 결과 기대, 사회 정의 관심이라는 사회 인지적 기제를 통해 사회 정의 실천에 어떤 영향을 주는 지를 살펴보았다. 이를 위해 서울 및 경기도에 거주하는 20대 537명을 대상으로 사회적 이슈 질문지, 사회적 바람직성 척도, 한국어판 공감 지수 척도를 포함하는 자기 보고식 설문조사를 실시하였으며, 사회적 바람직성을 통제한 뒤 연구 모형을 구조 방정식 모형을 통해 검증하였다. 분석 결과, 인지적 공감에 비해 정서적 공감의 영향력이 더 큰 것으로 나타났으나 두 변인 모두 사회 정의 실천에 유의한 영향력을 행사하며, 특별히 사회 인지적 기제를 거쳐 간접적으로 사회 정의 실천에 영향을 미친 것으로 나타났다. 이러한 결과는 공감 능력이 일반적인 이타행동 뿐만 아니라 사회적 불평등과 차별의 개념을 포함하는 사회 정의 실천 역시 예측한다는 것을 시사한다. 본 연구의 결과를 종합하여 정서적 또는 인지적 공감의 측면에서 사회 정의 실천을 촉진할 수 있는 방안을 제안하였다.

PURPOSE: The purpose of this study was to investigate the effect of multimodal intervention through VR (virtual reality)-based immersion program on the cognitive function and brain activity of patients with mild cognitive impairment. METHODS: The subjects of the study were 10 people in the experimental group who applied a complex intervention that performed cognitive tasks using the movement of the upper extremities through the VR program, and 10 people in the control group who received traditional occupational therapy. After the study intervention was applied 5 times a week, 30 minutes a day for a total of 8 weeks, LOTCA-G(Lowenstein Occupational Therapy Cognitive Assessment for Geriatric Population) and NIRSIT LITE were used to compare. RESULTS: Significant differences in cognitive function and brain activity were noted between the pre- test and post-test in the experimental group. Brain activity showed statistically significant differences in four channels of the working memory domain and one channel of the metacognitive domain (p < . 05). Comparative analysis of the difference between the two groups revealed statistically significant differences in cognitive function and brain activity. The brain activity showed statistically significant differences in three channels of the working memory domain and one channel of the metacognitive domain (p < .05). CONCLUSION: Through the results of this study, it was found that the complex intervention of performing cognitive tasks using upper extremity movements through the VR program had a positive effect on the cognitive function of patients with mild cognitive.

Objectives: The purpose of this study was to investigate the effect of handgrip strength level on cognitive impairment in hypertensive patients. Methods: This study used the first to eighth year data of the Korean Longitudinal Study of Aging (KLoSA). Of the 10,254 respondents who participated in the basic survey, respondents were included that they were diagnosed with high blood pressure and had no cognitive impairment. The handgrip strength was based on the highest value of handgrip strength for both hands. Cognitive function using MMSE results and 23 points or less were defined as cognitive impairment. Cox models were conducted to estimate the hazard ratios (HRs) of cognitive impairment in relation to handgrip strength adjusting for covariates. Results: In the case of hypertension patients, the probability of cognitive decline decreased by 3.0% every time the maximum handgrip strength increased by 1 unit. In the analysis by age, under the age of 64 had a 1.8% decrease in the probability of cognitive decline whenever the maximum handgrip strength increased by 1 unit, and a 3.6% decrease in those over the age of 65. In the gender analysis, male had a 3.2% decrease in the probability of cognitive decline for every 1 unit increase in the maximum handgrip strength, and female had a 2.6% decrease. Conclusions: The results of this study are expected to be used as basic data for the development of interventions to prevent cognitive decline in hypertensive patients by identifying the effect of handgrip strength level on cognitive decline. It is also expected to be used as basic data for health education on the necessity of increasing muscle strength for hypertension patients in the community.

Objective: The purpose is to verify that whether there are significant correlation between parent-teacher cooperation, quality of home environment, and mathematical interaction of parents and cognitive development of 3-year-olds, and the quality of home environment and mathematical interaction mediate the relationship between the parent-teacher cooperation and the cognitive development. Methods: A test was performed on 110 3-year-olds enrolledin a daycare center located in city S, and a questionnaire survey was conducted on their parents. We analyzed our data using SPSS WIN 21.0 and pearson's correlation, tested the mediating effect using regression, and used the Sobel test to check significance of the mediating effect. Results: Cognitive development of 3-year-olds was correlated with the parent- teacher cooperation, the quality of home environment, and mathematical interaction of parents. The quality of home environment showed complete mediating effect on the relationship between the parent-teacher cooperation and the cognitive development, and the mathematical interaction showed complete mediating effect on the relationship between the parent-teacher cooperation and the cognitive development. Conclusion/Implications: The parent-teacher cooperation indirectly predicts the cognitive development through the quality of home environment and the mathematical interaction. This research can contribute to the development of the family- institution connection program to facilitate the parent-teacher cooperation.

Purpose Among various psychosocial factors, negative social comparison, attention blocking to stimuli, and cognitive interference via information overload are considered most critical in hindering the effective performance improvement of computer-based idea generation. Given that the effect of negative social comparison along with a plausible solution based on the notion of performance feedback and goal setting has been successfully addressed, this study focused on the remaining issues of "attention blocking to stimuli and cognitive interference via information overload" and attempted to find a way to alleviate the effect of such process losses on performance. Design/methodology/approach A 2 × 4 between-subjects design was used, crossing cognitive ability (high and low) and personality (extroversion and introversion). Five subjects per each treatment were randomly selected to make the sample size equal. The group simulator was used to measure individual-level performance. The dependent variables were the quantity of and quality score of ideas. The manner by which these performance measures were operationalized was consistent with prior studies. An additional analysis using the number of diverse ideas was also conducted. Findings Three arguments were made in this study: (1) high cognitive individuals would perform better than low cognitive individuals, (2) extraverted individuals would perform better than introverted individuals, and (3) cognitive ability and personality would interact such that individuals in Q1 would have the highest performance. Cognitive ability had an effect on quality not quantity. Personality had an effect on both quantity and quality. An interaction between cognitive ability and personality was not found due to small sample size despite the use of the group simulator.
