본 논문에서는 MindWave와 AR 헤드셋 기기를 연동하여 자폐 스펙트럼 장애 아동이 불안감을 느낄 때 발산되는 뇌파 신호를 실시간으로 감지한다. 또한 실시간 객체 검출을 위한 YOLOv5 알고리즘을 통해 시각적 정보를 수집하여 해당 아동이 불안감을 느끼는 원인을 파악하고 이에 맞는 해결책을 AR 형태로 제시하며 자폐 스펙트럼 장애 아동이 불안감을 느끼면 보호자에게 알림을 전송하는 앱을 구현한다. 이를 통해 자폐 스펙트럼 장애 아동의 뇌파 안정과 정서 회복을 돕고 실생활에서 발생할 수 있는 돌발 상황을 방지할 수 있는 시스템을 제안한다.

Given that nowadays things get very fast due to the pervasive use of the Internet and mobile devices, decision-making time can be an important variable in the online economic decisions. Although in experimental and behavioral economics, measures like scores or earnings are usually preferred, this study argues that the time variable can be dealt with as a new decision outcome. Thus, by selecting some psychological factors presumably impactful in the online context (i.e., incidental emotions, psychological distances, and individual's impulsivity), this study tested their effect on decision time in the online centipede game. As a result, the mean decision time in the game was longer (1) in the happiness condition than in the anger condition and (2) in the friend condition than in the stranger condition. The people with attention difficulties spent a short time in the decision and the people who dislike complex problems spent a short time in explaining their decision. This study can contribute to the field as it used the decision time as the dependent variable and it tested the effect of psychological factors in the context of online decision-making. Future studies can be conducted in other online decision situations or by considering other psychological variables.

Asian gypsy moth, Lymantria dispar asiatica (Lepidoptera: Erebidae), which is an indigenous pest in Korea, a large outbreak has been reported in Gyeonggi-do, Chungcheong-do, and northern Gyeongsangbuk-do from 2019 in forest and nearby downtown areas, causing emotional damage to forests and city dwellers. During the indoor culture of gypsy moth eggs collected in Yecheon, Gyeongbuk in 2021 we found that 79.65% (321/403 of first instar larvae) were died due to Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV) infection. Sequence analyses of 36 gypsy moths collected from 12 regions in Korea using LdMNPV late expression factor-8 (lef-8) and polyhedrin (polh) genes showed a genetic variation of 0.80% and 0.86%, respectively. Comparison to GenBank data showed that the Korean samples were most similar to LdMNPV in Japan, whereas most different to those of Turkey. These results showed a high infection rate of LdMNPV in Korea and LdMNPV is one of the important population regulators of the gypsy moth.

This study is intended to draw a scale for problem behaviors of young children. To achieve this, an empirical survey was carried out on experts from three groups of daycare center teachers, kindergarten teachers and early childhood education-majored professors. A total of 209 items were measured by the scale for young children's problem behaviors from the 1970s to now. The results showed that 96 of a total 209 items in 5 categories related to the scale for young children's problem behaviors were adopted as major items. Using these 96 major items in 5 categories, 17 out of 40 items in a peer relationship category, 13 out of 41 items in a development category, 20 out of 50 items in a fundamental habit category, 22 out of 38 items in a morality category, and 24 out of 40 items in an emotion category were adopted. Most items were adopted in the emotion category, whereas most items were rejected in the development category. Therefore, it is judged that their problem behaviors are caused mainly by anxiety, shrinking, unexpected behaviors, dependence on parents or teachers, and slow behaviors due to the latent negative emotions of young children at the developing stage.
