본 연구의 목적은 도시 고령자와 농촌 고령자의 사회참여활동 유형이 인지기능 손상 정도(정상, 경증 인지기능저하, 중증 치매 의심)에 미치는 영향을 분석하는 것이다. 연구목적을 위해 6차(2016년)와 7차(2018년) 고령화 연구패널 조사 데이터 중 55세 이상 고령자 5,668명의 자료를 사용하여 다항 로지스틱 회귀분석을 하였다. 분석결과는 어떤 유형이든지 사회참여활동 하는 것이 인지기능 장애 위험을 줄여준다는 것은 도시와 농촌 둘 다 일관되게 유의하였으나, 도움이 되는 사회참여활동 유형이 도시와 농촌 간 차이가 있었다. 즉, 도시와 농촌에 사는지에 따라 정상군에서 인지기능저하 또는 치매 의심이 될 위험을 낮추는 데 도움이 되는 사회참여 활동 유형과 인지기능저하에서 치매 의심이 될 위험을 낮추는 데 유의한 유형이 달랐다. 따라서 인지기능 장애를 예방하고 치매 중증도를 완화하는 데 사회참여활동을 적극적으로 권장돼야 하며 적절한 지원이 필요하다는 것을 보여준다. 그리고 도시와 농촌의 차이를 고려한 정책과 개입이 요구됨을 함의한다.

This study was carried out to assess the degree of cognitive impairment and health status for the aged people in seoul area. The subjects were selected 117 aged at the nursing home and 101 residents from the community. To assess the cognitive function, Mini-Mental Status Examination(MMSE-K) and the assessement tool of health status for the elderly which was developed by Lee(1989) used to check the health status. The followings are the results of the Survey Study; 1. The elderly who were assessed as a cognitive impairment status was $47.9\%$ of the nursing home people and $42.6\%$ of the ordinary community residency elderly. 2. Health status of the community residency elderly was much better condition than the status of the nursing home residency elderly. 3. There was a significant relationship between the degree of cognitive impairment and the physical health status.

This study examines cognitive impairment, which is one of the results from social exclusion and leads to logical reasoning disorders. This study also investigate how cognitive errors called abductive inference error occur due to cognitive impairment. Present study was performed with 81 college students. Participants were randomly assigned to the group who has experienced social exclusion or to the group who has not experience the social exclusion. We analyzed how the degree of error of abductive inference differs according to the social exclusion experience. The group who has experienced social exclusion showed a higher level of abductive inference error than the group who has not experience. The abductive condition inference value of the group who has experienced social exclusion was higher in the group with the deduction condition inference value of 90% than in the group with the deduction condition inference value of 10%, and the difference was also significant. This study extended the concepts of cognitive impairments, escape theory, cognitive narrowing which are used to explain addiction behavior to human cognitive bias. Also this study confirmed that social exclusion experience increased cognitive impairment and abductive inference error. Future research directions and implications were discussed and suggested.

Objectives: This study investigated the effect of cognitive impairment on the association between social network properties and mortality among older Korean adults. Methods: This study used data from the Korean Social Life, Health, and Aging Project. It obtained 814 older adults' complete network maps across an entire village in 2011-2012. Participants' deaths until December 31, 2020 were confirmed by cause-of-death statistics. A Cox proportional hazards model was used to assess the risks of poor social network properties (low degree centrality, perceived loneliness, social non-participation, group-level segregation, and lack of support) on mortality according to cognitive impairment. Results: In total, 675 participants (5510.4 person-years) were analyzed, excluding those with missing data and those whose deaths could not be verified. Along with cognitive impairment, all social network properties except loneliness were independently associated with mortality. When stratified by cognitive function, some variables indicating poor social relations had higher risks among older adults with cognitive impairment, with adjusted hazard ratios (HRs) of 2.12 (95% confidence interval [CI], 1.34 to 3.35) for social nonparticipation, 1.58 (95% CI, 0.94 to 2.65) for group-level segregation, and 3.44 (95% CI, 1.55 to 7.60) for lack of support. On the contrary, these effects were not observed among those with normal cognition, with adjusted HRs of 0.73 (95% CI, 0.31 to 1.71), 0.96 (95% CI, 0.42 to 2.21), and 0.95 (95% CI, 0.23 to 3.96), respectively. Conclusions: The effect of social network properties was more critical among the elderly with cognitive impairment. Older adults with poor cognitive function are particularly encouraged to participate in social activities to reduce the risk of mortality.

PURPOSE: This study examined the effects of coordinative locomotor training on the physical factors for falls in the elderly with mild cognitive impairment. METHODS: This study examined thirty subjects diagnosed with mild cognitive impairment by the radiologic findings, history, and physical examination. The subjects were assigned to a control group (n = 15) or experimental group (n = 15, coordinative locomotor training). The experimental group underwent coordinative locomotor training for four weeks, with training sessions two times per week. The control group was given a fall-prevention education for 60 minutes without coordinative locomotor training. To evaluate the physical factors for falls, the lower extremity strength and the Korean version of the Fullerton advanced balance scale and biorescue were measured for balance. These tests were conducted before and after training. RESULTS: Significant differences were observed between the two groups after the four weeks of coordinative locomotor training for the elderly with mild cognitive impairment the experimental group had a greater degree of improvement in the physical factors for falls. CONCLUSION: These findings suggest that coordinative locomotor training may have a functional effect on fall-prevention and the mobility of the elderly with mild cognitive impairment. In addition, it is expected to provide systematic and effective data that can be used as a fall prevention program for the elderly with mild cognitive impairment in each institution.

Objectives : This prospective population-based cohort study was conducted to evaluate the risk factors of cognitive impairment and the degree of cognitive function change through a 5-year follow-up. Methods : The baseline and follow-up surveys were conducted in 1998 and 2003, respectively, Among 176 subjects who had normal cognitive function in the baseline study, 136 were followed up for 5 years. The cognitive function was investigated using the Korean version of the Mini-Mental State Examination (MMSE-K). The collected data were analyzed using SPSS and Stata. Results : Of the 136 subjects analyzed, 25 (18.4%) were cognitively impaired. Old age and low social support in the baseline survey were risk factors for cognitive impairment after 5 years. In the generalized estimating equation for 128 subjects except severe cognitive impairment about the contributing factors of cognitive function change, the interval of 5 years decreased MMSE-K score by 1.02 and the cognitive function was adversely affected with increasing age, decreasing education and decreasing social support. Conclusions : Although the study population was small, it was considered that the study results can be used to develop a community-based prevention system for cognitive impairment.

Purpose: This study was done to identify differences in factors influencing cognitive function according to the cognition of community dwelling elders. Methods: A convenience sample of 565 community dwelling elders participated in this study and from May to June, 2010 trained research assistants collected data using structured questionnaires. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, correlation, and multiple regression with the SPSS Win 15.0 version. Results: The elders had a slightly low degree of cognitive function. Of the 565 elders, 41.1% were in the normal group for cognitive function and 58.9% in the mild impairment group. Although there were no significant differences in general characteristics between the groups, factors influencing cognitive function were different. Factors influencing elders in the normal group were leisure activity and moderately good health status. These variables accounted for 5.7% of the variance in cognitive function. Factors influencing elders in the mild impairment group were leisure activity, depression, and education level limited to elementary school graduation. These variables accounted for 19.9% of the variance cognitive function. Conclusion: This study provides comprehensive understanding of factors influencing cognitive function in elders. Differentiated nursing interventions according to degree of cognitive function are suggested.

Purpose: The purpose of this study was to find out the degree of cognitive function among the elderly and to confirm its correlated factors. Methods: The subjects consisted of 392 elderly people over the age 65 who were living in Busan. Data were collected by the interview method, using a structured questionnaire and the K-MMSE scale. Results: The average points of the elderly's cognitive functions measured by K-MMSE were 23.76(${\pm}4.02$). With the cut-off point for cognitive impairment set as 24 points below using K-MMSE scale, 38.8% of the subjects have cognitive impairments. Among the variables related to cognitive functions, literacy showed the highest correlation with cognitive function(${\beta}=.330$, t=7.249, p<.001), followed in order by educational level, age, depression level, attendance of elderly's college, and religious activity. The total explanatory power of these variables is 36%. Conclusion: In order to prevent cognitive impairment among the elderly, elderly people have to maintain social relationships continuously, and expand the social network by participating in the related programs. Some efforts to prevent the occurrence of depression and to stimulate patients' brain activity need to be recommended.

Background and Purpose: Prospective memory (PM) has a known relationship with frontal function, and PM decline has been observed in amnestic mild cognitive impairment (aMCI). Cerebral small vessel disease, as evidenced by white matter hyperintensities (WMHs), is linked to frontal dysfunction. This study was undertaken to evaluate the relationship between PM decline and WMHs in patients with aMCI. Methods: Of 74 enrollees with aMCI, 69 completed this prospective study. We compared total scores and sub-scores of the Prospective and Retrospective Memory Questionnaire (PRMQ) administered at baseline and 3 months later, stratifying patients by degree of WMHs. Results: A significant decline was seen in PRMQ total scores and PM scores at the 3-month mark in patients with moderate (vs. mild) degrees of WMHs ($-2.8{\pm}7.2$ vs. $0.2{\pm}7.1$; p=0.032). In addition, patients with moderate (vs. mild) degrees of deep WMHs (DWMHs) showed greater PM decline, whereas PM loss in patients with mild, moderate, or severe degrees of periventricular WMHs (PVWMHs) did not differ significantly. Conclusions: Findings of this study indicate that the burden of WMHs is consistently implicated in PM deterioration experienced by patients with aMCI, and signifies greater PM decline, especially in instances of extensive DWMHs. Greater attention to the change of PM is therefore needed in aMCI patients with WMHs.
