  • The purpose of this study was to find out the effects of electroencephalograph (EEG) power and coherence on cognitive function in normal elderly, non-demented elderly with mild cognitive impairment, and demented elderly during working cognition tasks. Forty elderly women (19 demented elderly, 10 non-demented elderly with mild cognitive impairment, 11 norma1 elderly) participated in this study, All subjects performed working cognition tasks with Raven's CPM while EEG signal was recorded, EEGs were measured continuously at rest and during the working cognition task. EEG power and coherence was computed over 21 channels: right and left frontal, central, parietal, temporal and occipital region. We found that there were more correct answers among normal elderly women than in other groups Owing the working cognition task, ${\Theta}$ wave at Fp1, Fp2 and F8, a wave at Fp2, ${\beta}$ wave at Fp1, Fp2. F4 and F8 of the frontal region was increased significantly in the demented elderly group. On the other hand. ${\Theta}$ wave at Fp1, Fp2 and F7, ${\beta}$ wave at Fp1, Fp2, F3 and F7 of the frontal region was increased significantly in the group of non-demented elderly with mild cognitive impairment. In contrast. in the normal elderly group, all of the ${\Theta}$ wave and ${\beta}$ wave at Fp1, Fp2, F3, F4, F7 and F8 of the frontal region (except ${\beta}$ wave at F3) was increased significantly, These results suggest that the nerves in prefrontal and right hemisphere regions were most active in the demented elderly group during problem solving, and the nerves in the prefrontal and left hemisphere lobe were most active in the group of non-demented elderly with mild cognitive impairment. In contrast, me majority of nerves in the frontal region were active in the normal elderly group.

  • Alzheimer's disease is a form of dementia that can be managed by identifying the disease in its initial phases. In recent times, numerous computer-aided diagnostic techniques utilizing magnetic resonance imaging (MRI) have demonstrated promising outcomes in the categorization of Alzheimer's disease (AD). The OASIS MRI dataset was utilized which has 80,000 brain MRI images. It is suggested to resample this dataset as it is highly imbalanced and posed a challenge in preventing bias toward majority class while employing the convolution neural network (CNN) model for classification. This paper examines and extracts patterns and features of 461 patients taken from the OASIS dataset. The research has aimed at utilizing the Base Model of EfficientNetV2B0 with custom classification layers, and simplified custom CNN model, also exploring Multi-class classification across four distinct classes: Non-Demented, Very Mild Demented, Mild Demented, Moderate Demented in addition to binary classification as Non-Demented and treating other classes as demented. Furthermore, different dataset sizes were experimented with 5,000 and 20,000 for each class to be discussed in this paper. The experiment results indicate that EfficientNetV2B0 achieved the accuracy of 98% in binary classification, 99% in multiclass. Whereas custom sequential CNN model in multiclass classification presents the accuracy of 96% for 20,000 dataset size and 98% for 80,000 dataset size.

  • Purpose: The purpose of this study was to identify premorbid personality, depression and disturbing behaviors to provide information for developing nursing interventions for the pre-demented and mild demented elderly living as residents of their community. Method: The survey was conducted through direct interviews using a structured questionnaire in J city. Among the subjects contacted, 89 made appropriate replies to the survey. Result: The subjects' disturbing behaviors were significantly related to premorbid personality and depression. The predictors to disturbing behaviors of the pre-demented elderly were sex, extroversion, neuroticism and conscientiousness. The predictors to disturbing behaviors of the mild demented elderly were agreeableness, depression, sex, conscientiousness, and extroversion. Conclusion: In conclusion, disturbing behaviors of pre-demented elderly and mild demented elderly are affected not only by their premorbid personality but also by their depression. Therefore, it is necessary to encourage and respond to them with understanding their disturbing, behaviors in 'relation to their premorbid personality. In addition. it is important to maintain positive emotion in order to reduce their disturbing behaviors.

  • The purpose of this study was to test the effects of music therapy on cognitive function and depression in demented old adults. This study was made with one -group in a pre- and post-test design. The subjects were seven demented old adults over, sixty-five years and with mild to moderate cognitive impairment, residing at a nursing home. Music therapy was given by one researcher and one research assistant for thirty to forty minutes twice a week for 4 months. Music therapy was conducted with the subjects both listening and singing with a cassette player and a double-handed drum. In order to evaluate the effects of music, we measured the level of cognitive function and depression at the beginning and at the end of the music therapy session by means of an MMSE- K developed by Kwon and Park and the Depression Inventory developed by Chon. The Data were analyzed using descriptive statistics and a paired t - test analysis using a SPSS PC package. The results are as follows: 1) The subjects of the music therapy showed improvement in cognitive function. The MMSE-K score was significantly increased after music therapy. Especially, memory recall was very significantly. 2) The subjects of the music therapy showed a slight decrease in depression. However, there was no significant difference in the degree of depression between mean scores measured before and after music therapy. The results suggest that music therapy is effective in improving and maintaining cognitive function in demented old adults. And we suggest that long-term music therapy will be required to improve depression in demented old adults. These findings are encouraging the idea that music therapy may improve cognitive impairment.

  • 연구목적 본 연구는 치매 군과 비치매 군의 통증 역치 및 통증 경험의 특성을 비교 하고자 한다. 방 법 2010년 강원 조기치매 검진사업의 일환으로 시행된 것으로, 연구 대상은 지역사회 거주중인 65세 이상 노인 8,302명이었다. 이 중, 한국판 간이정신상태검사(MMSE-KC) 점수가 저하 된 1259명을 선별했고, 이중 365명이 한국형 치매 진단평가 도구(CERAD-K)를 이용한 정밀검진을 받았다. 검사 결과 및 전문의의 판단 하에 정상, 경도인지장애, 치매 군으로 진단 후, 최종 비치매 군 90명, 치매 군 57명이(경도-중등도 알츠하이머형 치매) 분석되었다. 압통각계(Pressure algometer)를 이용하여 실험적으로 통증 역치를 측정했고, 자가보고식 검사인 Brief pain inventory(BPI)를 이용하여 통증 경험(통증 심도, 통증 방해도)을 조사했다. 집단 간 차이 분석은 Pearson Chi-Square와, 혼란변인(성별, 나이, 교육수준, GDS, 당뇨)을 보정한 ANCOVA검정을 시행했다. 결 과 인구학적 특성상 치매 환자 군에서 여성이 많고, 연령이 높고, 교육 연수가 낮았다. 통증 역치는 두 군에서 통계적으로 의미 있는 차이가 발견되지 않았다. BPI결과에서 비치매 군이 어깨 통증, 전체 통증 개수, '통상적 일'의 통증으로 인한 방해를 의미 있게 더 많이 호소했다(p<0.05). 그러나 두 군에서 통증 유병률 및 치료는 차이가 없었다. 결 론 치매 군은 비치매 군보다 통증을 더 적게 경험했다. 이는 치매 환자의 통증 역치는 보존되었으나, 내성이 증가한다는 선행 연구를 뒷받침 하는 증거로 여겨진다. 따라서, 치매 환자를 위한 적극적인 통증 사정 및 치료를 제안한다.

  • Purpose: This study aimed to explore influencing factors on care burden among family caregivers for elders with dementia living at home. Methods: Participants in this study were 211 family caregivers who were taking care of elders registered at a support center for dementia located in S-gu, Seoul. Data were collected using a structured questionnaire. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression in SPSS WIN 23.0. Results: The care burden of family caregivers was mild to moderate ($40.31{\pm}21.50$) in this study. The factors influencing care burden among family caregivers for elders with dementia were the age, behavioral problems, and dependency in instrumental activities of daily living of demented elderly, in addition to the perceived health status and resting hours of family caregivers. Overall, these factors explained 46.5% of the total variability in care burden in this sample (F=13.01, p<.001). Conclusion: Findings from this study suggest that the characteristics of demented elderly and family caregivers can influence care burden differently. Individually tailored strategies based on the various caregiving contexts need to be developed to reduce the level of care burden among family caregivers for elders with dementia.

  • 본 연구는 대구시 소재 기억의 주간보호시설을 활용하여 경증치매 노인대상의 인지활동을 중심으로 한 인지재활 프로그램을 개발하여, 지역사회 경증 치매노인에게 유용한 복지서비스를 제공함을 연구목적이다. 현재 우리나라에서는 아직 현 실정에 맞는 치매 환자에 대한 지역사회기반의 통합적 중재 프로그램에 대한 개발이 많이 이루어지지 않아 이에 대한 프로그램 개발이 절실히 필요하다. 본 연구의 경증치매노인 인지재활사업은 주로 지역사회 기반의 보호시설 등의 집단시설에서 적용하기에 적합한 경증치매환자 관리에 근간이 될 수 있다고 본다. 하지만 경증치매환자는 개인적 차로 인해 환자 모두가 동일하지 않고 인지재활방법과 그 효과는 분명히 차이가 있다. 결과적으로 개별적으로 적합한 전략에 의해 그 효과를 높일 수 있을 것으로 기대되며 이전 보다 특성이 있고 개별화된 노인요양 케어 프로그램의 개발도 연계될 것으로 사료된다.

  • Purpose: The purpose of this study is to grasp the welfare service for the demented people staying at home and the service that caregivers want to use. Therefore, we are going to develop a Korean senile dementia-care management model. Method; It analyzed the data of 185 demented people and caregivers, who registered in 16 public dementia care centers in B city since June 2002. Results: 1) The types of services used by the aged people with dementia staying at home were, in the order of frequency of use, the day-care center(26.5%), and home-help service (21.6%). 2). The types of services according to the degree of dementia were as follows; mild cases: home care service (5.4%), moderate cases: day-care service (40.0%) and severe cases: day-care service (26.0%). 3). The caregivers who want to use senile welfare institutions accounted for 23.3%, and the major reason they could not use the institutions was due to their economic situation. 4) The Korean senile dementia care management system must be excuted, considering caregivers' economic state and severity of dementia. Since the system was actively operated, many small sized welfare service institutions showed development. Conclusion: The welfare services appropriate to the severity of dementia should be provided. With the model developed in this study, the dementia management requires sufficient care and should be achieved to reduce the caregivers burden.

Method: A total of 13 elders with mild dementia in the data care center were participated. Manual and guideline of data care program was developed. Data care program was composed of movement/exercise, foot massage, music therapy, horticultural therapy, and art therapy. Data care program was performed by trained intervener for 32 weeks. Instruments were physical functioning such as hand grip strength., vital capacity, chiar stand test, sit and reach test, one leg standing, Berg' Balance scale, 6m Walk Velocity, stair climb, ADL, GDS-K, MMSE-K, Integrative Social Functioning Scale, cortisol, Ig A and Ig G. These were measured at the baseline, 16-week, and 32-week post-intervention by the trained nurses. Data were analyzed as Wilcoxon signed rank test. Results: For Hand grip, balance, and vital capacity, there was a significant difference between baseline and 16-week post-intervention(p<.05). For one leg standing, 6m velocity, there was a significant difference between 16-week post-intervention and 32-week post-intervention(p<.05). For Stair climb, there was a significant difference between baseline and 32-week post-intervention(p<.05). For depression and social functioning, there was no significant difference among baseline, 16-week, and 32-week post-intervention. For cognitive functioning, there was a significant difference between baseline and 32-week post intervention(p<.05). There was a significant difference of cortisol, and Ig G between baseline and 32-week post-intervention(p<.05). Conclusion: It would appear that physical fitness, functional performance, ADL, depression, social and cognitive functioning, and physiological indicator of community dwelling elders with dementia can be improved through day care program using multiple stimuli.
