This study aimed to verify the mediating effects of cognitive function and social support and to establish a structural relationship between child maltreatment and resilience in school-age children (n=357) taken in by child protection service. In the first model (linear arrangement), each protective factor mediates independently between maltreatment and resilience; in the second model (arrangement in due order), cognitive function has mediating effects prior to social support. Analysis of data included descriptive statistics, Cronbach's a, confirmatory factor analysis, and structural equation modeling. Results of the first model showed indirect effects of cognitive function and social support. Results of the second model significantly affirmed that the mediators, cognitive function and social support, diminish negative effects of maltreatment by bolstering resilience.

Evidence regarding the efficacy of Ginkgo biloba extract on cognitive function has been contentious. This study evaluated the effective period of G. biloba intake to improve cognition in the elderly. PubMed, EMBASE, Cochrane, Web of Science, and PsycArticles databases were searched for short-listing relevant studies. Twenty-five studies fulfilled the inclusion criteria. Cognitive efficacy was assessed based on the duration of intervention. G. biloba intake for 3-6 months statistically significantly affected cognitive function (SMD= -0.21; 95% CI -0.39, -0.03; p=0.02). However, the improvement in activities of daily living (ADLs) was not statistically significant. Thus, G. biloba intake for more than three months improves cognition in the elderly people with cognitive impairment and AD dementia without any safety risk. Intake for up to six months does not improve ADLs significantly in mild to moderate dementia patients.

The purpose of this study was to identify differences in cognitive function according to the presence or absence of apraxia and the tasks most relevant to the cognitive function among the various types of tasks in the apraxia test. The subjects were 42 community residents who participated in a cognitive rehabilitation program related to dementia in a Chungbuk area. MMSE-K and BCoS(Birmingham Cognitive Screen) apraxia test were administered to all subjects. The apraxia test includes three types of tasks, gesture production tasks that make meaningful movements according to verbal instructions, gesture recognition tasks that display behavior after make sense of meanings, and meaningless imitation task. Apraxia group(n=30, MMSE-K mean score: 25) showed lower cognitive function than group without apraxia(n=12, MMSE-K mean score: 28). All tasks in the apraxia test showed a significant correlation with cognitive function, but the meaningless imitation task had a negligible correlation. The apraxia test is a good way to assess cognitive function, and it may be more effective to use meaningful behavior to replace cognitive testing.

Objective: The purpose of this study was to get the cognitive reaction time according to the intensity of auditory stimuli in older people and to differentiate the cognitive reaction time between older people and adults. Method: 49 subjects consisted of 32 older people and 17 adults. Cognitive reaction time was assessed with Simple Auditory Reaction of Foundation I in PSS CogReHab. Analysis of the data was done by using independent t-test. Results: The results were as follows: 1. There was a significant difference of the mean of cognitive reaction time to the intensity of auditory stimuli. 2. There was no significant difference from older people regardless of sexual distinction in mean of cognitive reaction time. However, there was a significant difference of the mean of cognitive reaction time in adults. 3. There was a significant difference between older people who got a job or not in 90 dB of auditory stimuli. 4. The mean of cognitive reaction time to the intensity of auditory stimuli in older people was slower than adults. There was a significant difference of the mean of cognitive reaction time between older people and adults in 70 dB of auditory stimuli. 5. The mean of cognitive reaction time to the intensity of auditory stimuli in older people did not have the significant difference in scholastic ability. Conclusions: The results of the study showed slowing of the cognitive reaction time in auditory stimuli to aging in older people.

Purpose : This study aims to investigate the effect of instrument-activities daily living training through client-centered home visitation on the cognitive functions, occupational performance, and instrument-activities daily living of elderly at the cognitive support grade(Grade6). Methods : The subject of this study was a 66-year-old woman living in G Metropolitan City, who has been diagnosed with Alzheimer's and mild dementia. The study period was from March 17, 2020 through June 12, 2020, and the A-B-A' design, among the individual case experiments, was adopted as the study design. For the data analysis, descriptive statistic and visual analysis using graph were used for the change of cognitive functions, occupational performance, and instrument-activities daily living. Results : The instrument-activities daily living provided through client-centered home visitation improved the subject's cognitive functions, occupational performance(performance, satisfaction) and instrument-activities daily living. Conclusion : This study showed that daily life training through client-centered home visitation can help elderly people at the cognitive support grade select for themselves the problems of daily life caused by cognitive decline and practice specific action plans, thereby enabling them to maintain and improve the cognitive functions necessary for the performance of activities, such as comprehension, memory, and thinking skills. In addition, it is thought that the activities based on the subject's preferences, performance, and sense of importance assured the subject of feelings of motivation and the possibility of participation, and had a positive effect on the subject's performance speed and rate. With the above in mind, Instrument-activities daily living client-centered home visitation is proposed as a potential practical intervention program for individuals. It can help elderly people at cognitive support grade to maintain and improve their functions, thereby delaying the progress of their condition to severe dementia.

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: This study aimed to investigate the impact of a 12-week combined cognitive and physical exercise program on cognitive and physical functions in older adults diagnosed with mild cognitive impairment (MCI). Design: A one-group pretest-posttest study. Methods: Twelve participants with MCI engaged in a weekly 60-minute session of combined cognitive and physical exercise program. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), while physical function was evaluated through measures of muscle strength, postural balance, and walking capabilities. Muscle strength assessments included the arm curl test, handgrip strength, and the 5 sit-to-stand test. Postural balance was evaluated using the one-leg stance test, timed up-and-go test, functional reach test, and four square step test. Walking function was analyzed through a gait analysis device. Pre- and post-intervention measurements were compared to determine the effects of the exercise program. Results: The results demonstrated significant improvements in MoCA, arm curl test, timed up-and-go test, walking speed, and cadence following the 12-week intervention (p<0.05). MoCA scores revealed enhanced cognitive performance, while measures of muscle strength, including the arm curl test, exhibited significant changes. Improvements in timed up-and-go test scores indicated enhanced mobility, accompanied by increased walking speed and cadence, as evidenced by gait analysis. Conclusions: This study suggests that a structured 12-week program incorporating both cognitive and physical exercises can lead to meaningful improvements in cognitive and physical functions among older adults with MCI.

인지 보존능력(CR)이란 보완적 뇌 연결망을 통해 인지적 수행력을 최적화 또는 극대화시키는 능력이다. CR은 노화에 따른 인지-언어 능력의 저하를 완화 또는 지연시키는 데 기여한다. CR 및 정상 노년층의 인지-언어 능력 간 상관성을 체계적으로 살펴본 국내 메타분석 연구는 거의 드문 편이다. 본 연구에서는 2000년 이후 게재된 국내외 문헌 중 총 32개 논문을 대상으로 메타분석을 실시하여 상관성을 체계적으로 검증하고자 하였다. 그 결과, CR의 유형은 교육수준과 인지자극 활동, 다중언어 사용, 직업 순으로 많았고, 인지-언어의 하위 영역 중에는 기억력, 전반적 인지능력, 언어능력이 대다수를 차지하였다. 또한, CR과 인지-언어 능력 간 상관성은 '중간' 정도였으며, 기억력, 언어능력 등이 여러 CR 유형과 유의한 상관성을 보였다. 본 연구는 CR이 정상 노년층의 인지-언어 능력에 미치는 효과성을 체계적으로 분석함으로써 증거 기반적 자료를 제공할 수 있다는 점에서 의의가 있다.
