Advances in medical technology and living standards have led to an age of aging. In addition, the development of technology and the popularization of computers have led to the development of the contents business and the release of several functional games. Among these functional games, silver functional games are being played to solve problems such as dementia, a major problem in the aging era. In this study, prior research was analyzed to suggest factors that help design based on the kinetic elements of the design method of the motion-based convergence game for the leisure use of the silver generation. Based on the analysis, the model of exercise factors for preventing dementia is presented. This research design a silver motion-based functional game using the anti-dementia exercise model presented in this study in the future, we expect to see an effective and efficient silver game in the long term.

The purpose of this study was to present the empirical data for the prevention of suicide by analyzing the group differences according to the types of risk factors and protective factors of family members living with dementia patients and the effects of each type on suicidal ideation. This study investigated the characteristics of suicidal ideation among family members of people living with dementia by using a community health survey. It then investigated the effect of each latent group on the suicidal ideation of family members of people living with dementia. Twenty-four risk and protective factors on suicide ideation were analyzed by using Mplus. The four latent classes were high risk - low protective, high risk - high protective, low risk - high protective and low risk - low protective. Multivariate logistic regression analysis showed that the high risk-low protective factor group had the highest suicidal ideation. Based on these results, practical implications and challenges were presented.

The purpose of this study was to determine the factors associated with duration of postoperative delirium following orthopedic joint surgery. This study included 266 patients who underwent orthopedic joint surgery at a single university hospital between January 2012 and February 2014. Patients were divided into two groups according to the duration of delirium: the transient (${\leq}2$ days) and prolonged (>3 days) delirium groups. Of the 266 patients, 137 (52%) developed prolonged delirium. Incidence of pre-existing dementia and history of stroke were significantly higher in the prolonged delirium group than in the transient delirium group. In a multivariate regression model, pre-existing dementia and history of stroke were associated with increased duration of delirium. Our findings suggest that medical practitioners should pay special attention to the prevention and management of postoperative delirium in patients who have dementia or stroke and undergo orthopedic joint surgery.

The objective of the present study was to investigate the effect of eye movement on cognitive ability using Mini-Mental State Examination for Dementia Screening (MMSE-DS) and the amplitude and latency of P300 from event-related potentials after 55 elderly participants were randomly stratified into the saccadic eye movement (SEM) group and the smooth pursuit eye movement (SPEM) group, and performed eye movement for 4 weeks. As a result, P300 amplitude significantly increased and P300 latency significantly shortened in the SEM and SPEM groups. MMSE-DS showed a significant increase in both groups; upon comparing the groups, the SEM group showed a significant difference in orientation and the SPEM group in attention. In conclusion, it is thought that SEM and SPEM can improve and maintain the cognitive ability of the elderly and may be used as therapeutic tools for dementia prevention and mild dementia.

Objective : The aim of this study was to verify the equivalence and effectiveness of the tablet-administered Korean Repeatable Battery for the Assessment of Neuropsychological Status (K-RBANS) for the prevention and early detection of dementia. Methods : Data from 88 psychiatry and neurology patient samples were examined to evaluate the equivalence between tablet and paper administrations of the K-RBANS using a non-randomly equivalent group design. We calculated the prediction scores of the tablet-administered K-RBANS based on demographics and covariate-test scores for focal tests using norm samples and tested format effects. In addition, we compared the receiver operating characteristic curves to confirm the effectiveness of the K-RBANS for preventing and detecting dementia. Results : In the analysis of raw scores, line orientation showed a significant difference (t=-2.94, p<0.001), and subtests showed small to large effect sizes (0.04-0.86) between paper- and tablet-administered K-RBANS. To investigate the format effect, we compared the predicted scaled scores of the tablet sample to the scaled scores of the norm sample. Consequently, a small effect size (d≤0.20) was observed in most of the subtests, except word list and story recall, which showed a medium effect size (d=0.21), while picture naming and subtests of delayed memory showed significant differences in the one-sample t-test. In addition, the area under the curve of the total scale index (TSI) (0.827; 95% confidence interval, 0.738-0.916) was higher than that of the five indices, ranging from 0.688 to 0.820. The sensitivity and specificity of TSI were 80% and 76%, respectively. Conclusion : The overall results of this study suggest that the tablet-administered K-RBANS showed significant equivalence to the norm sample, although some subtests showed format effects, and it may be used as a valid tool for the brief screening of patients with neuropsychological disorders in Korea.

The purpose of this study is to investigate the factors that affect the social distance between the demented elderly and nursing college students. In this study, responses from 158 nursing college students in city D were collected using structured questionnaires and analyzed. As a result, the correlation between variables, social distance, and dementia attitude towards the demented elderly (r = .53, p<.001) showed a statistically correlated relationship, while ageism (r = -.41, p<.001) showed a negative correlation. The results of this study are as follows: first, the interactions between the elderly with dementia and the nursing college students were more frequent (${\beta}=.29$ p=.012), and second, attention to early prevention of dementia (${\beta}=.32$ p=.002) was significant. The explanatory power of these influential factors on the social distance toward the demented elderly was 41.0%.

This study aims to investigate the performance and satisfaction of occupational therapists at the Dementia Relief Center for health care of the elderly in local communities, and to provide basic data necessary for role establishment by checking occupational therapists' tasks according to the priority. The subjects of this study were occupational therapists in dementia care centers in the Honam area and Gwangju Metropolitan City, who were surveyed via mail and e-mail. The survey had a total of 54 items covering the general characteristics of the therapists and current state of the centers (n=8), performance and satisfaction with the service areas and task content of the centers (n=45), and tasks that were considered important (one short-answer question). It was found that occupational therapists at the Dementia Relief Center were mainly carrying out the "Dementia Prevention Management Projects", which provided the programs for the patients, and they showed the highest satisfaction. Although the 'MMSE-DS' is occupational therapists' own area with high performance and satisfaction, it was not assigned to the occupational therapists at the Dementia Relief Center, indicating that the role was insufficient. The tasks related "administrative works and strengthening community capacities" showed low performance and satisfaction, but they are essential for the operation of the Dementia Relief Center and the management of the patients, so the plans to increase the occupational therapists' performance should be established. The categories of projects that occupational therapists consider important were also consistent with those they had to perform. It means the occupational therapists at the Dementia Relief Center recognized their unique roles. In this context, to establish the role of occupational therapist at the Dementia Relief Center, it is necessary to amend the operating guidelines based on the performance, satisfaction, and priorities of the projects, and to develop the curriculums and programs that can improve the tasks with insufficient performance and low satisfaction.

Fermented milk including yogurt, which has a long tradition of thousands of years, was first established in Korea in 1919, and the current market size has grown to over 90 billion dollars. Fermented milk, which began in the early days of liquid yogurt, appeared on the market as spoonable and drinking yogurt. Fermented milk began with research on intestinal health functions and lactobacilli, and gradually developed into various disease prevention studies such as gastrointestinal health, immunity improvement, skin beauty, and prevention of dementia. As a simple meal, it has a nutrient function element, which serves as a meal replacement, and is expanding its range from general foods to special-purpose foods and dietary supplements. Fierce market competition is taking place, and as a result, the domestic fermented milk market is developing through the development of various products for differentiation.
