Based on the K-UAM roadmap, this study was conducted to select major education and training subjects necessary for the composition of the initial UAM pilot education and training curriculum. Currently, UAM aircraft have similar characteristics to rotorcraft that can take off and land vertically around VTOL functions. Therefore, in this study, the Rotary Wing Pilot Training Curriculum of the Army Aviation School, which represents Rotary Wing Flight Education, was selected as a comparative group, and education and training subjects for initial UAM pilot training were selected. First, a hierarchical structure for the AHP survey was designed based on the Army's rotorcraft pilot education and training subjects, and the AHP survey was conducted by selecting experts from each class. If the education and training subjects given as priorities through AHP analysis are applied to initial UAM pilot training, it is expected to contribute to the effect of education and training and ultimately to the safe operation of UAM.

Securing large amounts of training data in deep learning neural networks, including convolutional neural networks, is of importance for avoiding overfitting phenomenon or for the excellent performance. However, securing labeled training data in deep learning neural networks is very limited in reality. To overcome this, several augmentation methods have been proposed in the literature to generate an additional large amount of training data through transformation or manipulation of the already acquired traing data. However, unlike training data such as images and texts, it is barely to find an augmentation method in the literature that additionally generates bio-signal training data for convolutional neural network based human activity recognition. Thus, this study proposes a simple but effective augmentation method of bio-signal training data for convolutional neural network based human activity recognition. The usefulness of the proposed augmentation method is validated by showing that human activity is recognized with high accuracy by convolutional neural network trained with its augmented bio-signal training data.

The purpose of this study was to identify the factors influencing vocational training participation among individuals aged 65 and older in order to enhance their employability. According to the research findings, the educational background and economic activity status of the elderly significantly impact their participation in vocational training. It was confirmed that economic activity and vocational training are closely related to the capacity development and increased employability of the elderly. Moreover, a considerable number of elderly individuals express a continued desire to work, and this group tends to participate more in vocational training. This underscores the importance of promoting vocational training among the elderly and developing suitable models, which holds significant policy implications. Logistic regression analysis revealed that gender, education, economic activity, desire to work, and pension income affect participation in vocational training. This highlights the necessity of formulating specific strategies in government support policies, particularly for those with lower educational backgrounds. Additionally, the study emphasizes the importance of approaches that encourage vocational training participation, especially among those with lower pension income.

RLHF(Reinforcement Learning from Human Feedback, 인간 피드백 기반 강화학습) 방법론이 최근 고성능 언어 모델에 많이 적용되고 있다. 이 방법은 보상 모델과 사람의 피드백을 활용하여 언어 모델로 하여금 사람이 선호할 가능성이 높은 응답을 생성하도록 한다. 하지만 상업용 언어 모델에 적용된 RLHF의 경우 구현 방법에 대하여 정확히 밝히고 있지 않다. 특히 강화학습에서 환경(environment)을 담당하는 보상 모델을 어떻게 설정하는지가 가장 중요하지만 그 부분에 대하여 오픈소스 모델들의 구현은 각각 다른 실정이다. 본 연구에서는 보상 모델을 훈련하는 큰 두 가지 갈래인 '순위 기반 훈련 방법'과 '분류 기반 훈련 방법'에 대하여 어떤 방법이 더 효율적인지 실험한다. 또한 실험 결과 분석을 근거로 효율성의 차이가 나는 이유에 대하여 추정한다.

The purpose of the present study was to examine whether Interpersonal Cognitive Problem Solving(ICPS) skill training would enhance interpersonal solving skills and behavioral adjustment of mildly mentally retarded adolescents in the junior and high school. The program used in the present study was shortened and adapted for mildly retarded adolescents from Shure and Spivack(1982) program which was developed to improve the adjustment of children in the intermediate grades 5-6. The subjects were 22 mildly retarded adolescents, and they were assigned to either the experimental(11) or the control group(11). The experimental group were given ICPS training 4 times a week over a period of 8 weeks with a total of 32 sessions in all. The results showed a significant improvement of alternative thinking and consequential thinking in the experimental group compared with the control group. With regard to behavioral ratings by the parents and teachers, there were no significant differences between the groups. The results indicated that the training was effective in increasing the ability to generate alternative solutions and to predict consequences, but the significant improvement of interpersonal cognitive problem solving skills did not lead to noticeable improvement in behavioral adjustment. It was suggested that a longer training period for over-learning, concomitant parent education program, and more behaviorally oriented social skill training combined with the cognitive approach would yield significant training effects, maintenance and transfer.
