Purpose: Because carbon monoxide (CO)-intoxicated patients with an alert mental status and only mild cognitive dysfunction may be inadequately assessed by traditional bedside neurologic examination in the emergency department (ED), they may not receive appropriate treatment. Methods: We retrospectively investigated the incidence and features of cognitive dysfunction using the Korean version of the Mini-Mental State Examination (MMSE-K) in ED patients with CO poisoning with alert mental status. We conducted a retrospective review of 43 consecutive mild CO poisoned patients with a Glasgow Coma Scale score of 15 based on documentation by the treating emergency physician in the ED between July 2014 and August 2015. Results: Cognitive dysfunction, defined as a score of less than 24 in the MMSE-K, was diagnosed in six patients (14%) in the ED. In the MMSE-K, orientation to time, memory recall, and concentration/calculation showed greater impairments. The mean age was significantly older in the cognitive dysfunction group than the non-cognitive dysfunction group (45.3 yrs vs. 66.5 yrs, p<0.001). Among the initial symptoms, experience of a transient change in mental status before ED arrival was significantly more common in the cognitive dysfunction group (32.4% vs. 100%, p=0.003). Conclusion: Patients with CO poisoning and an alert mental status may experience cognitive dysfunction as assessed using the MMSE-K during the early stages of evaluation in the ED. In the MMSE-K, orientation to time, memory recall, and concentration/calculation showed the greatest impairment.

Purpose: The purpose of this study was to identify the effects of the tailored group exercise program on perceived health status, physical strength, depression and cognitive function in seniors. Methods: The subjects were 42 seniors of the experimental group and 28 seniors of the control group. The exercise program tailored by physical fitness was carried out for 16 weeks. The dependent variables were measured by Perceived Health Status Scale, The Senior Fitness Test, MMSE-K, and GDS-K. The collected data were analyzed by Fisher's exact test, Chi-square test and t-test, and ANCOVA using the SAS program. Results: In terms of physical strength and depression there was significant difference among groups. Perceived health status and cognitive function were not significant different among groups. Conclusion: In this study, the tailored exercise program was effective and safe for the elderly, and resulted in improving physical and psychological health status in the elderly. This demonstrated that the tailored group exercises program on the basis of the subject's fitness, played an essential role in maintaining and improving the health.

The purpose of this study was to evaluate the factors influencing the ambulatory status in hemiplegia with intracerebral hemorrhage after rehabilitation. Thirty patients with stroke who was admitted in the Chosun University Hospital, between from January 1st' 1998 and December 31st' 1998, were included in this study. The following variables as a potential predictors for ambulation were evaluated at treatment of the stroke onset; 1) general characteristics including age and sex, and 2) clinical characteristics including frequency and onset time of the stroke, affected side, duration of the treatment, time interval between onset and rehabilitation, manual muscle test of paretic limb, sitting and standing balance, proprioception, perception, cognitive function. We compared and analyzed the these variables to the two type of ambulatory status at the time of the discharge by Modified Barthel Index, independent, dependent. The data were analyzed by student t-test, Fisher-exact test, Mann Whitney-U test, $X^{2}$-test, correlation analysis(spearman's). The results were as follows; 1. Were no significantly inflenced independent ambulatory status among general characteristics. 2. Frequency of the stroke and proprioception (p<0.05), muscle strength of the lower limb, cognitive function and standing balance (p<0.01), perception and sitting balance (p<0.001) were significantly inflenced independent ambulatory status among clinical characteristics. 3. Independent Variable correlated with the ambulatory status were muscle strength of the lower limb, proprioception and sitting balance (p<0.05), standing balance, frequency of the stroke, perception and cognitive function (p<0.01). Therefore the muscle strength of the lower limb, proprioception, sitting balance, standing balance, frequency of the stroke, perception, cognitive function were the most significant influencing factors of ambulatory status after rehabilitation.

The purpose of this study was to assess the effects and find the correlation of LOTCA-G and SS-QOL on the cognitive function and quality of life of elderly stroke patients. The time period of the experiment was from March 1, 2018 to March 30, 2018, and the study sample was composed of 102 stroke out-patients who participated in the rehabilitation center in G-city and received treatment of LOTCA-G and SS-QOL. The raw scores of the cognitive function of the elderly stroke patients varied depending on their gender, age, education, and marital status, but the differences were not statistically significant. Second, the raw scores of the quality of life of the elderly stroke patients varied depending on their gender, age, education, and marital status, but only marital status showed significance (p <0.01). The elderly stroke patients' cognitive function and the quality of life showed a statistically significant correlation (p <0.01). LOTCA-G and SS-QOL generally showed significant correlation even among sub-categories, but energy, one of the sub-categories of quality of life, did not show significant correlation with any of the other sub-categories of cognitive function. By combining the study results, it was possible to see that there were high levels of correlation between cognitive function and quality of life in elderly stroke patients shown through LOTCA-G and SS-QOL. Based on this study, if the raw scores of cognitive function and quality of life could be validated and various basic data could be provided for increasing quality of life, it can be considered that the stroke patients' quality of life will be improved.

This study was conducted to develop a theoretical model for the determinants of activities of daily living in Korean rural elderly people. The theoretical model was derived from Lawton's Ecological Model to explain human behavior. The model includes determinant variables for functional status such as age, sex, physical status, cognitive status, physical environment, social environment, and depression. Data for this study was collected from 189 elderly people in a rural district near Chonju City. The data was analyzed with SPSS PC/sup +/4.1 and LISREL 8. The analysis of the data showed that the first proposed theoretical model did not fit the collected data well. In order to increase the fit of the model to the data, the model was modified by deleting the exogenous variables of sex, physical environment, and social environment. The fit of the modified model to the data was increased and was move suitable. The results of this study show that the determinants of the activities of Korean rural elderly people were age, perceived physical condition, cognitive status, and depressional status. Age has a significant direct and indirect effect on the activities of daily living of rural elderly people. Perceived physical condition has a significant indirect effect through depression on activities of daily living. Cognitive status also has a significant indirect effect through depression on functional status. Depression has a significant direct effect on the functional status. Physical environment and social environment showed reversal relationships to functional status. In conclusion, the results of this study show that personal characteristic factors are more important than environmental characteristic factors for functional status of elderly people. However, the importance of depression to functional status in Korean rural elderly people and the reverse relationship between social environment and functional status, reflect Korean specificity. Korean nursing needs to focus more on this Korean specificity in order to develop nursing knowledge and practice appropriate to Korean people.

Purpose: We aimed to describe and compare the cognitive function, anxiety, and quality of life for the demented elderly in day care centers or nursing homes. Methods: We selected 44 subjects from day care centers and 63 subjects from nursing homes by performing convenience sampling. The Korean version of Mini Mental Status Examination was used for measuring cognitive status; Rating Anxiety in Dementia, for assessing anxiety; Korean Version of Quality of Life-Alzheimer's Disease, for assessing the quality of life. The data were collected from May to June 2008 and analyzed by SPSS/WIN 14.0. Results: 1) The cognitive function of the subjects in the day care center was higher than that of the subjects in the nursing home. Anxiety in the subjects in the nursing home was higher than that in the subjects in the day care center. 2) The cognitive function and quality of life of the subjects in the day care center showed statistically significant correlation, 3) The anxiety and quality of life of the subjects in the nursing home showed statistically significant correlation. Conclusions: Nursing interventions that improve the quality of life of the demented elderly should be considered and applied according to the degree of cognitive function and anxiety.

Objectives: This study aimed to confirm the association between cognitive function and oral health status in the elderly. Methods: In this study, 5,794 respondents, aged 55 or older, who had participated in the 7th aging research panel survey were used. Statistical analyses were performed using a complex samples cross-tabulation analysis, complex samples general linear model, and a complex sample multinomial logistic regression analysis. Results: After analyzing the cognitive function of the elderly according to their oral health conditions, it was found that suspicions of dementia (19.6%) and cognitive function decline (25.9%) were more common for those who wore dentures than for those who did not wear dentures (p<0.001). Compared to those who did not wear dentures, those who wore dentures were linked to a 1.665 times higher suspicion of dementia (p<0.001). In comparison, cognitive decline was 0.964 times lower when the number of natural teeth increased by 1, and it was 0.941 times lower when the oral health evaluation index for the elderly increased by 1 point (p<0.001). Conclusions: As a result of this study, it was confirmed that cognitive function and oral health status are related in the elderly. Therefore, systematic measures for oral health management and oral health promotion should be prepared in tandem with awareness of possible cognitive decline in the elderly.

Objective : To examine the association between dietary factors and cognitive impairment in older Korean women living in the community. Methods : Wave 2 data, from the Suwon Longitudinal Aging Study (SLAS), of 365 women aged 65 years or over, were used. The Korean version of the 30-point Mini-Mental State Examination (MMSE-K) was used to assess cognitive impairment (score$\geq$19). Dietary habits and frequencies of food group consumption were also examined. Results : A total of 67 women (18.4%) were found to be cognitively impaired. In bivariate analyses, nondietary factors, such as age, marital status, education, income, self-rated health, depression, emotional support, social activity, exercise, and dietary factors, such as self-rated nutritional status, frequency of beans and bean products and milk and dairy products consumption were associated with cognitive impairment. In the multivariate analysis, a higher frequency ($\geq$1 vs. <1 time/day) of beans and bean products (OR=0.48, 95% CI: 0.23-0.99) and milk and dairy products (OR=0.25, 95% CI: 0.10-0.61) consumption was inversely associated with cognitive impairment, after adjustment for non-dietary factors. Conclusion : These results suggest that dietary factors may play a significant role in cognitive impairment of older Korean women.
