The purpose of this study was to investigate the effect of white noise on memory and attention of local community elderly during computer-based cognitive rehabilitation program(COMCOG). 30 elderly subjects were recruited and conveniently allocated into experimental and control group. Experimental group subjects carried out COMCOG with white noise. Control group subjects received COMCOG for 30 minutes, 3 times per week for 6 weeks. Neurocognitive funtion test(CNT) were used to evaluate memory and attention during pre and post. The most CNT outcome at post was significantly improved than the pre outcome in the both group(p<.05). And the experimental group showed significantly difference from control group(p<.05). The result of this study show that the COMCOG with white noise may be appropriate for improving memory and attention in elderly. This will enable the application of COMCOG with white noise in cognitive rehabilitation therapy of local elderly and it will help guide the selection of the therapist as one therapeutic basis

본 논문에서는 키넥트 센서 기반의 치매 예방 애플리케이션을 설계하고 구현한다. 이 애플리케이션은 노년층의 치매 예방을 위해 기억력을 향상시키고 간단한 동작으로 운동을 촉진할 수 있는 햄버거 만들기 게임을 구현한다. 햄버거 만들기 게임은 키넥트 센서 기반으로 조인트와 스켈레톤 기능을 활용하여 하늘에서 떨어지는 재료들을 순서에 맞게 획득하여 햄버거를 완성함으로써 점수를 얻는다. 사용자들은 제한 시간이 끝날 때까지 계속 진행하며 순서를 기억해 내는 과정을 통해 기억력을 향상시키고, 재료를 잡기 위한 활동적인 움직임으로 치매 예방에 도움이 되는 운동 기능을 제공한다.

We have developed a serious game for the elderly named 'Paldokangsan3' as a next version of 'Paldokangsan2' which was a walking game with memorization in shopping streets using controllers of hand buttons and foot boards with PC developed in 2012. The interface of had buttons and food boards were changed into the interface of motion capture with the aid of Kinect. The expected effects are improvement of memorization, improvement of concentration ability to find out items in the vision, improvement of vitality through physical walking actions, as well as improvement of mental health through entertainment activities of game play. We have tested 25 volunteers of more than 65 years old in Cheonan city community center for the elderly for 2 weeks. We got the result that the game play was showing positive effectiveness on memorization, physical exercise and self-esteem in mental health area of the elderly.

본 논문에서는 치매 등 인지기능 저하에 따른 질병을 예방하기 위한 기능성 퍼즐 게임을 설계하고 구현하였다. 치매 등 인지기능 저하에 따른 질병은 고령층에서 주로 나타난다. 이에 따라 게임의 UI와 규칙은 가급적 단순해야 하며, 동시에 기억력과 판단력, 반응속도는 향상시킬 수 있도록 해야 한다. 본 논문에서는 고령층에서도 쉽게 조작할 수 있도록 UI를 단순화시켰으며, 순간적인 인지능력과 단기기억력 및 판단력을 향상시킬 수 있는 색맞추기 퍼즐게임을 설계하고 구현하였다.

Objective: The purpose of this study was to examine the effect of the Spaced Retrieval Training (SRT) with Errorless learning on the elderly with Mild Cognitive Impairment (MCI)'s memory, Instrumental Activities Daily Living, Depression symptom. Methods: A single subject experimental research with ABA design was conducted in this study on the 78-years-old person who was enrolled in day-care center. The total experimental sessions were 16 which composed of 3 sessions for baseline, 10 sessions for intervention and 3 sessions for second baseline. K-Auditory Verbal Learning Test (K-AVLT) was measured for the memory each session. For the measurement of cognitive function, IADL, depression Symptom, Korean version of Montreal Cognitive Assessment (MoCA-K), Philadelphia Geriatric Center Instrumental Activities Daily Living (PGC IADL), Geriatric Depression Scale Korean Version (GDS-K) was measured at pre-post test. Results: Memory at the phase B was improved than Phase A. At the phase B, the scores trend was ascending, but after the intervention at the phase A', the scores trend was descending. The scores of MoCA-K were improved, PGC IADL were maintained, GDS-K were decreased. Conclusion: This results support the evidence of the SRT with EL on the elderly with MCI in the clinical setting. In the future, the correlation researches about MCI's memory and other functional factors will be needed for effective occupational therapy service.

The present study was conducted to evaluate the effects of extract from Eriobotrya japonica leaves (EJE) on cognitive impairment induced by scopolamine, a muscarinic antagonist, in rats. Scopolamine injection (1 mg/kg, i.p.) impaired performance in rats in the passive avoidance test as well as in water maze test and severely reduced cholinergic system reactivity, as indicated by reduced acetylcholine levels and increased acetylcholinesterase activity. Daily administration of EJE significantly increased step-through latency in the passive avoidance test, reduced escape latency, and increased time spent in the platform quadrant in the Morris water maze test. EJE protected against scopolamine-induced cholinergic system deficit, including reduced acetylcholine levels and increased acetylcholinesterase activity in whole brain homogenates. These results suggest that EJE provides a significant anti-amnesic effect against scopolamine-induced cholinergic system deficits and cognitive impairment.

Objective : The purpose of this study was to identify the effects of Interactive Metronome (IM) training on short-term memory and attention for children with mental retardation. Methods : For this study, single-subject experimental research was conducted using an ABA design. We observed two children, twice a week for 9 weeks, which was 18 sessions in total. We evaluated the children's brain waves without intervention and the child's pseudo randomly selected sample of one short-term memory task as assessed in the baseline A phase for three sessions. In the intervention phase the children received 40-50 minutes of Interactive Metronome training twice a week, a total of 12 sessions. The short-term memory test and long form test as assessed after treatment, without brain wave in short form test measuring. During the baseline A phase, data were collected using the same procedure as the baseline A phase. Results : After the interactive metronome training, positive changes was observed in brain waves, attentions and short-term memory. Conclusion : The results of this study expect that IM training has a potential for improving cognitive functions of children with mental retardation. In addition, the results of this study can be used as basic data in attention and short-term memory of occupational therapy intervention for children with mental retardation.

This study is an experimental study on the single group pre-post test design for the effects of the food expression activity program on subjective memory, depression, and self-expression of the elderly. 36 elderly people attending Senior Citizen Club from two locations in S City participated. A total of six session programs were applied from January 8 to February 17, 2020. The questionnaire survey conducted subjective momory, depression, and self-expression before and after the program. The contents of the intervention consisted of physical relaxation, cognitive activities, and various food activities. In the result of this study, the food expression activity program were statistically significant differences in subjective memory(t=2.67, p=.011), depression(t=3.88, p<.001), and self-expression(t=2.09, p=.044). Therefore, it is expected that the food expression activity program can be applied as a nursing intervention to reduce depression and improve subjective memory and self-expression in the elders attending senior citizen clubs.
