The purpose of this study was to investigate the effects of early cognitive training and tailored telephone coaching program for ischemic stroke. Among 28 participants, assigned into the experimental(n=15) and control group(n=13). Only the experimental group was received a 4-week cognitive training and 11 session of tailored telephone coaching. The effect ot the program was evaluated four times(baseline, 4weeks, 8weeks, 12months) using the tool on Depression, Mini Mental State Examination(MMSE), Neuropsychological battery, Activities of Daily Living(ADL). The repeated measures ANOVA showed that the experimental group showed improvement in MMSE, verbal memory and executive function compared to the control group. Especially, the improvement of executive function which is related to ADL was a remarkable result. This suggests that early intervention is very important for recovery cognitive function and independent daliy life after stroke, and periodic telephone coaching should be done together for mid-to long term effects.

PURPOSE: This study measured the impact of a 12-week fall-prevention exercise program on balance, ambulatory ability, lower limb strength, and psychosocial characteristics in older adults diagnosed with dementia. METHODS: The participants comprised 31 older adults (9 men, 22 women) diagnosed with Alzheimer's or vascular dementia at a long-term care hospital located in Gunsan City. A fall-prevention exercise program was provided to the experimental group, while the control group was only provided with instruction and materials related to the fall-prevention exercise program. The participants were evaluated before the intervention, 6 weeks after the intervention, and 12 weeks after the intervention on static and dynamic balance abilities (using Timed Up and Go test: TUG, Tinetti-balance scale, one-leg standing test: OLS), gait (Tinetti-balance scale, 6-minute walk test: 6MWT), lower limb strength (sit to stand test; STS), and psychosocial characteristics (Short Form 36 Health Survey-Korean version, Korean Mini-Mental State Exam). RESULTS: An independent samples t-test and repeated measures analysis of variance were used for the statistical analysis. There were statistically significant improvements after the intervention (p<.05) in dynamic balance abilities (TUG and OLS using the left foot), gait (6MWT), and lower limb strength (STS) for the experimental group, but not for the control group. No difference was seen in psychosocial characteristics. CONCLUSION: Older adults with dementia who participated in the fall-prevention exercise program showed significant improvements in their static and dynamic balance abilities, lower limb strength, and ambulatory ability after the intervention.

Objectives : This study analyzed the differences of body mass index(BMI) in Korean patients with Alzheimer's diseases(AD), Mild Cognitive Impairment(MCI), and healthy controls to verify whether low BMI is associated with cognitive impairment. Furthermore, this study also sought to examine any association between BMI and Mini Mental State Examination-Korean version(MMSE-K), Clinical Dementia Rating(CDR), and Global Deterioration Scale(GDS). Methods : A total of 257 subjects were included in the study. History taking, mental status examination, physical examination and neurocognitive function test were carried out for the diagnosis of AD and MCI. The subjects' demographic data and presence of diseases were also surveyed. The overall cognitive function and severity of diseases were assessed using MMSE-K, GDS, and CDR. Results : The order of BMI was found to be healthy controls>MCI>AD, with statistically significant differences among the groups. The order of MMSE-K scores was similar, with healthy controls>MCI>AD in statistically significant differences. The healthy controls had the lowest CDR and GDS scores, and AD patients had the highest scores. There was a significant positive correlation between BMI and MMSE scores(r=0.238, p=0.000). BMI was negatively correlated with CDR(r=-0.174, p=0.008) as well as with GDS(r=-0.233, p= 0.000). Conclusions : Measuring BMI of patients with AD or MCI is expected to be meaningful in that BMI could be a clinical indicator of AD. We expect this to be beneficial for the diagnosis, prevention, and therapeutic approach of AD and also expect large-scale, long-term longitudinal studies to follow.

Objectives: Sound and light (SL) stimulation has been used as a method to induce some useful mental states in the fields of psychology and psychiatry. It is believed that sound and light entrainment device (SLED) has some specific effects through synchronization of EEG in patients who use it. Theta frequency is believed to stimulate deep relaxation and short term memory processing. This study was conducted to evaluate if 4-10 Hz SL stimulation can induce relaxation and improve short term memory function. Methods: Ten medical students with no medical or psychiatric problems participated in this study. Subjects were randomly divided into two groups. One group was applied with real SLED was applied to one group (R group) and pseudo SLED to the other group (P group). The two groups were exposed to SL stimulation with SLED 15 minutes a day for 5 days, and after two days rest the two groups were switched over. The Korean Wechsler Adult Intelligence Scale (K-WAIS), Academic Motivation Tests (AMT), Test Anxiety Scale (TAS), Korean Auditory Verbal Learning Test (K-AVLT), and digit span were used to evaluate short term memory. Spielberger's State-Trait anxiety inventory and heart rate variability (HRV) test were used to evaluate degree of relaxation. Results: Compared with S group, R group showed a significant improvement in K-AVLT and digit span after a single application of SL stimulation. But 5-day long application did not reveal any differences between the two groups. A significant change in HRV was observed in 5-day long application of SL stimulation after being switched over to other SLED. Conclusion: This pilot study suggests that 4-10 Hz SL stimulation has some positive influences on short term memory and relaxation.

Objectives : Chronic alcohol consumption has been known to result in various neurocognitive deficits. Many neuropsychological studies revealed that the major disturbances occurred in the executive function, learning and short-term memory, visuospatial performance function, perceptuo-motor skills, and abstraction and problem solving abilities. This study was done to identify which cognitive areas might be mainly affected. Methods : The cognitive disturbance was evaluated using the Korean Version of the Mini Mental State Examination(MMSEK) and the 7 Minute Screen(7MS) in male inpatients with alcohol dependence(N=3 : as well as in age and education level matched healthy male controls(N=30). Four individual tests of the 7MS were consisted of the Benton Temporal Orientation Test, the Enhanced Cued Recall, the Clock Drawing and the Category Fluency. Results : 1) The average scores of four individual test of the 7MS for the alcoholics were $2.77{\pm}4.38$ for the Benton Temporal Orientation Test, $13.90{\pm}2.02$ for the Memory Test(the Cued Recall $6.77{\pm}1.94$, the Uncued Recall $7.10{\pm}2.45$), $5.84{\pm}1.86$ for the Clock Drawing, and $12.58{\pm}3.29$ for the Category Fluency. Except the Benton Temporal Orientation Test, there were statistically significant differences between test scores of alcoholics and those of controls(p<0.01). 2) The alcoholics who had MMSE-K score <24 were 9.68%. The average(${\pm}S.D.$) score of the MMSE-K for the patient group($27.23{\pm}2.62$) was significantly(p<0.001) lower than that of the healthy controls($29.20{\pm}1.24$). There were no statistically significant differences between four individual test scores of the 7MS of alcoholics with the MMSE-K score <24(N=3) and those of alcoholics with the MMSE-K score ${\geq}24$(N=28). 3) Four individual test scores of the 7MS seemed to have statistically significant association with such variables as MMSE-K, duration of alcohol drinking, blood magnesium concentration, liver function and thyroid function. Conclusion : Mild deficits of cognitive areas such as orientation, memory, visuospatial abilities and verbal fluency could be found in alcohol dependence.

In this study we compared the cognitive function (Mini-Mental State Examination for Dementia Screening: MMSE-DS) and nutrient intake of elderly women with dementia in a long-term care facility (EW-LCF) and a day-time care facility (EW-DCF). This survey was conducted from July 2015 to May 2017 on 73 elderly women with dementia (47 women in LCF and 26 women in DCF) in the city of Incheon. The data obtained from interviews with the subjects and caregivers were analyzed using the SPSS 20.0. The total score of the MMSE-DS and intakes of most nutrients in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). The nutrient adequacy ratios (NAR) of protein, vitamin A, C, $B_6$, $B_{12}$, thiamin, riboflavin, niacin, folic acid, calcium and phosphorus in the EW-LCF were significantly lower compared to the EW-DCF (p<0.05). However, the indexes of nutritional quality (INQ) of vitamin C, $B_6$, thiamine, niacin, calcium, magnesium, and iron in the EW-LCF were significantly higher compared to the EW-DCF (p<0.05). As a result, the subjects showed an unbalanced and insufficient nutrition intake status regardless of the type of care facility. Most nutrient intakes of the EW-LCF with lower cognitive function were very significantly lower compared to the EW-DCF (p<0.001). Therefore, it is necessary to assess the cognitive function and nutritional status regularly at care facilities for the elderly women suffering with dementia and to provide specialized individual nutritional management.

This study examined the effectiveness of 'Forest Therapy (FT)' from the biological, neurocognitive and psychosocial perspectives. Adolescents who were classified as potential internet addicts took part in a FT program for two (once or twice) or three days. Before and after participating the program, Serum Brain-derived neurotrophic factor (BDNF), Comprehensive Attention Test (CAT), Children's Depression Inventory (CDI), and State Anxiety Inventory (STAI) were measured. It was found that FT led to positive consequences, indicated by increased serum BDNF, improved CAT performance, reduced internet use desire, greater resilience, and better social relationship. In addition, FT was partially effective in alleviating state anxiety level, when the participants were classified in accordance with FT exposure lengths. Overall, this study provides evidence that FT reduces symptoms related to internet addiction and promotes various qualities required for well-being.

Due to the growing popularity of mobile information technology, more people, especially in the general public, have access to computerized geospatial information systems for wayfinding tasks or urban navigation. One of the problems with the current services is that, whether the users are exploring or navigating, whether they are travelers who are totally new to a region or long-term residents who have a fair amount of regional knowledge, the same method is applied and the direction are given in the same way. However, spatial knowledge for a given urban region expands in proportion to residency. Urban navigation is highly dependent on cognitive mental images, which is developed through spatial experience and social communication. Thus, the wayfinding service for a regional community can be highly supported, using well-known regional places. This research is to develop the framework for urban navigation within a regional community. The concept of communal ontology is proposed to aid in urban regional navigation. The experimental work was implemented with case study to collect regional landmarks, develop the ontological model and represent it with formal structure. The final product of this study will provide the geographical information of a region to the other agent and be the fundamental information structure for cognitive urban regional navigation.

The purpose of Emergency Medical System(EMS) is what a patient returns to society with recovering mental tone in the shortest time as giving prompt and proper medical treatment to patient in emergency situation, and the Correctional Administration(CA) is purposed for the convict to return and settle down to society after release from prison in success as executing schooling, enlightenment activity, vocational training to convict who was quarantined from the society for the term of imprisonment. The EMS and CA will coincide each other which is reverting people to society in safety. This study aims to suggest the developmental program of EMS in correctional facilities through the cause of emergency situation, system, human resources, establishment, medical equipments, state of budget and the point issue for safety of victim who has many chances that is exposed to physical damage and disease because of particularity of lower culture in correctional facilities and the staff who works there. First, in the view of the correctional facility security system, a proper number of the emergency rescuers should be employed. Second, the effective transportation system along with some emergency medical equipment needs to be established. Third, the correctional officers and the prisoners should be learned the first-aid training which is realistic, practical and systematic. Fourth, the cooperative system should be established such as 1339 emergency medical information center in society. Fifth, the Ministry of Health and Welfare must increase EMS budget for correctional facilities.

The purpose of this study is to clarify the concept of the frail elderly and to obtain theoretical evidence. The research method was conducted using the basic principles for conceptual analysis of Walker and Avant(2005). As a Result of a review of the literature about how to utilize the concept of a frail elderly, frail elderly might be in the intermediate state of health and disease. They can be defined as physically vulnerable in the sarcopenia, inflammation, insulin resistance, and preceding advanced disease, lead to hospitalization, falls, disability, and death. The attributes were physiological, psychological, and socio-environmental and economic factors, so they had multidimensional factors. They were required the assist daily living of another person. Also, their attributes had decreased the amount of recovery time and degree, and exhaustion. The attributes of frail elderly consisted of these facts: dynamic process, multidimensional factors, dependency, vulnerability. The frail elderly was a dynamic process that involves the possibility of change to health and disease, and include physical, mental, cognitive, and social environmental factors. In addition, the frail elderly was difficulty in daily life, physical vulnerability and difficulty in adaption. In conclusion, frail elderly as defined by the results of this study will contribute to the foundation of health care systems, including community visiting nursing to understand the level of frail elderly and systemic management to do not go into long term care.
