This study proposes a novel approach to enhancing the social inclusion and participation of individuals with developmental disabilities. Utilizing cutting-edge virtual reality (VR) technology, we designed and developed a metaverse simulator that enables individuals with developmental disabilities to safely and conveniently experience indoor handicapped handball sports. This simulator provides an environment where individuals with disabilities can experience and practice handball matches. For the modeling and animation of handball players, we employed advanced modeling and motion capture technologies to accurately replicate the movements required in handball matches. Additionally, we ported various training programs, including basic drills, penalty throws, and target games, onto XR (Extended Reality) devices. Through this research, we have explored the development of immersive assistive tools that enable individuals with developmental disabilities to more easily participate in activities that may be challenging in real-life scenarios. This is anticipated to broaden the scope of social participation for individuals with developmental disabilities and enhance their overall quality of life.

This study aimed to quantify the attitude toward doping among handball players and to identify the influence of players' demographic information, knowledge of doping, education of anti-doping on the attitudes toward doping. 385 elite handball players (193 adolescent players, 165 adult players) were participated in this study and filled in the questionnaire about demographic information, knowledge of doping, education of anti-doping and Performance Enhancement Attitude Scale (PEAS). Collected data were analyzed by Stepwise multiple linear regression. Adult players were more generous about doping than adolescents, and, adolescent players' attitudes toward doping were influenced by their gender and age. In adults, attitudes toward doping were related with only the gender. These results would be useful information to develop the effective anti-doping strategy for handball play.

The purpose of this study is to collect official records of the 2019 Men's and Women's Handball World Championships to identify important shooting variables that determine the team's record of winning or losing. After collecting 192 games of men's and women's national teams from 24 countries and verifying the difference in competition records according to the winning and losing groups, the decision tree method, one of the data mining techniques, is analyzed. According to the analysis, the 9m shooting success rate and Near shooting success rate were the most important factors for both men and women. Men win 83.3% if the 9m shooting success rate is 32.5% or higher and the Near shooting success rate is 67.5%, and women win 75% if the 9m shooting success rate is 75% or more and the Near shooting success rate is 51%. Also, the women's yellow cards are considered important variables that determine victory or defeat. In conclusion, both men and women were able to identify the factors of winning and losing decision shooting, but follow-up studies are needed considering the relativity of various record variables and performance in future handball.

본 연구는 A체육대학교 옥내운동장 5곳을 선정하여 현재의 조명환경을 파악하고 수평면 및 수직면 조도를 측정하고 분석하였다. 고천장인 실내테니스장 배드민턴장, 핸드볼장과 저천장인 유도장과 탁구장을 선정하여 측정한 결과 평균조도는 실내테니스장 483[lx] 배드민턴장 272[lx], 핸드볼장 471[lx], 유도장 284[lx], 탁구장 370[lx]로 기준조도보다 상당히 낮게 측정되었다. 수직연 조도와 균제도도 권장치보다 낮게 나왔으나 연습경기장이므로 수평면조도를 충분히 보완한다면 연습하는 데는 큰 무리가 것으로 보인다. 전반적으로 조명환경이 열악하고 설비가 노후화되어 있으므로 시설보수 시 시뮬레이션을 활용하여 종목별 경기특성에 맞는 환경을 갖추도록 연구검토가 필요할 것으로 판단되었다.
