Present study identified categorization pattern differences between experts and novices and examined whether categorization training has positive effects on problem solving. In experiment I, we examined categorization differences between groups according to expertise using mathematical equation problems. Experts classified problems based on deep structure related to problem solution methods whereas novices classified problems based on surface features. However, in the labeled categorization condition, novices' categorization pattern was not different from experts'. These results suggest that novices have difficulty identifying deep structure of problems. In experiment 2, we examined whether categorization training showing subjects deep structure of problems explicitly increases transfer performance. The results showed that solution training was more effective to expert group whereas categorization training was more effective to novice group. We have discussed that different training methods should be applied according to expertise.

The purpose of this study was to review the effects of the physical fatigue induced by overtraining on cognitive information processing and emotional change of athletes by neurophysiologic study. And to provide basic data for the athletes and coaches in the sports field to improve understanding of the overtraining symptoms from the brain physiological point of view. We reviewed the domestic and international academic materials and research reports published in the last 20 years using electronic databases and examined the literature that is consistent with the purpose of this study among the retrieved documents. Based on the reviewed literature, we examined the cognitive information processing and emotional change of the athlete according to the training, and overtraining can accumulate the fatigue of the body, which can cause severe side effects in terms of cognitive ability and emotional ability of athletes as well as deterioration of performance. The study using P300 and EEG cerebral hemispheric asymmetry difference indices also confirmed the possibility of a new approach to understand psychological and physiological effects of overtraining on information processing and emotional changes.

Objective : The purpose of this study was to examine the effect of multi-sensory stimulation training on cognitive function and balance skill of the community resident elderly. Methods : 10 participants who is over aged 65 years carry out multisensory stimulation training program for 12weeks, once a week for 60minutes. The multisensory stimulation training program is consisted of total 12 topic based on body schema, gross muscle and tactile stimulation. The result was measured using Mini-Mental State Examination-Korean and Berg Balance Scale to evaluate before and after of cognitive function and balance skill. And after intervention, the satisfaction of the program was investigated. Wilcoxon matched-pair signed rank test was used to compare pre- post difference of cognitive function and balance skill. Results : There was significant difference in cognitive function and balance skill(p<.05) and the satisfaction is positive at the end of the program. Conclusion : The multisensory stimulation training program has positive effects on cognitive function and balance skill for elderly. And the satisfaction is positive at the end of the program. The multisensory stimulation training program can enhance the satisfaction to elderly in the aging society. So, additional studies is needed for efficient use.

This study is single-group pretest-posttest design study to examine the effects of web-based cognitive training program using tablet on cognition and depression in the elderly with high risk of dementia or mild dementia living in a rural area, enrolled in dementia center. Intervention was provided to the 18 participants once a week for 10 weeks within 1 hour. Data was analyzed with SPSS 24.0 and interview data was categorized. The study result proves that after intervention, the participants' cognitive score increased significantly(Z=-3.35, p=.001) and the depression scores were significantly decreased(Z=-3.13, p=.002). Also, interview shows positive effect of the intervention on cognition and depression. It is necessary to improve access environment for smart devices so as not to be restricted by time and place, and to develop and apply various types of web-based programs for each cognitive level. Then, the intervention could be used as a cognitive training program incorporating information and communication technology for the prevention and management of dementia in rural areas.

본 데이터 GAN 기법 데이터 증강기법을 적용하여 가속도 데이터를 증강하는 방법에 대해 연구한다. 가속도 데이터는 사람의 활동패턴을 인지하는데 있어 가장 기본적인 데이터로 활용된다. 가속도 데이터를 증강한 뒤, 활동패턴을 인지하는 머신러닝 모델 훈련에 사용한 결과 생성한 데이터가 육안으로 확인하였을 때 실제 데이터와 유사한 패턴을 형성하였고, 실제 활동패턴인지 모델 훈련에 사용한 결과 정확도(Accuracy)는 기존 데이터로만 훈련한 경우 74%인데 비해 증강된 데이터를 혼합하여 훈련하였을 때 약 88%로 개선된 것을 확인하였다.

Recently, the need to prevent or treat cognitive impairment in older adults has been arising. In particular, they tried to diagnose MCI as an early stage of Alzheimer's disease and to delay the progression to dementia through training cognitive function. Most of cognitive function training have been manufactured to game contents which related to several cognitive function, and it needs to be verified quantitatively whether subjects are paying attention to cognitive function training. Thus in this study, we measured and analyzed EEG signals while performing attention training game contents. As an analysis method, we utilized CI, which shows how much they are focusing on, and RI, which shows how stable they are. The result of this study can be seen that all the subjects' CI were increased, which means that the subjects performed game contents with concentration.

항해사가 타선과의 충돌위험 인지 및 피항을 위한 Radar/ARPA 교육훈련은 오래전부터 STCW협약에 의하여 각 해양계열 및 수산계열 교육기관에서 실시되는 교과목명, 교육시간, 교육내용이 상이한 것으로 조사되었다. 하지만 각 교육기관에서 발행한 이 교육훈련과 관련한 증서는 동일한 효력을 가지고 있다. 이에 Radar/ARPA 교육훈련 내용의 세부사항이 표준화될 필요가 있으며, 최저 평가에 대한 표준도 필요할 것으로 판단된다. 본 연구는 Radar/ARPA 교육환경 개선 및 시나리오 개발, 실습노트, 평가 툴(Tool)에 대하여 개선하고자 하여 이들을 개발 제안하여 이 교육훈련의 효율적인 교육방안을 위한 기본적인 표준모델을 개발하고자 한다.

This research examined the effects of individual differences on visual discrimination skill teaming and its transfer to novel stimuli. Individual participants were categorized as having an analytic or holistic cognitive style, high or low working memory capacity, and high or low levels of rationality, experientiality, and adaptive decision-making styles. Participants received easy or difficult training for the serially presented discrimination task, and then transferred to novel discriminations. Training content interacted with cognitive style and working memory capacity to affect transfer accuracy performance, but individual differences in decision-making styles did not affect transfer performance. Results suggest individual differences should be taken into account when designing an interface for visual discrimination.
