This study conducted a survey on visitors who visited the 2021-2022 KBL Professional Basketball Stadium in Wonju to understand how professional sports viewing factors affect the club image, club satisfaction, and club reputation. As factors for watching professional sports, four factors were considered: stadium, game situation, spectating cost, and spectator promotion. A total of 450 questionnaires were distributed and 411 questionnaires excluding 39 questionnaires were used as the final analysis data. For the effective questionnaire survey, After analyzing the purpose and purpose of the research, participants were asked to collect data. The collected data were analyzed using SPSS statistical package after data coding and cleaning process. The results of this study are as follows. First, the effect of professional sports viewing factor on brand image was 45.1%, and the factor of pro sports viewing was significant in stadium, competition situation, and promotion of viewing, and had no effect on viewing cost. Second, the influence of professional sporting factor on the satisfaction of the team was 42.5% in explaining power, which was significant in the stadium, the competition situation, the cost of visiting, and promotion of viewing. Third, the influence of professional sports viewing factor on team reputation was 62.1%, and the factor of professional sports viewing was significant in promoting stadium, visiting cost, and viewing, and had no effect on economic situation. The implication of this study is that in order to increase the brand value of the club, it is much more effective to increase the quality of facilities and food and beverages and to activate events for the audience than to lower the cost of viewing.

This study empirically analyzes the effect of a sports club's performance and social media operations on online information search volume, reflecting fan engagement. Additionally, it confirms that such effect can vary depending on the issuance of sports fan tokens. The analysis of the data resulted in the support of all four hypotheses presented in this study. The team's goal differentials during the games exhibited a significant and positive effect on the online information search volume by fans. Furthermore, the quantity of a team's social media posts also showed a significant and positive effect on the online information search volume. The aforementioned effects of the team's game-related performance and social media activity on the online information search volume appeared to be strengthened when the sports fan tokens of the team were issued. This study conducts an empirical analysis of fan engagement in sports clubs and delves into the marketing dimensions of sports fan tokens. By doing so, it broadens the research scope within sports marketing and offers practical insights for the development of marketing strategies by sports clubs.

Silicon heterojunction technology (HJT) solar cells have received considerable attention due to advantages that include high efficiency over 26%, good performance in the real world environment, and easy application to bifacial power generation using symmetric device structure. Furthermore, ultra-highly efficient perovskite/c-Si tandem devices using the HJT bottom cells have been reported. In this paper, we discuss the unique feature of the HJT solar cells, the fabrication processes and the current status of technology development. We also investigate practical challenges and key technologies of the HJT solar cell manufacturers for reducing fabrication cost and increasing productivity.

하지 웨어러블 로봇의 근력 보조 성능을 극대화하기 위해서는 착용자의 보행 상태를 인식하는 보행 위상 추정 기술이 필수적으로 요구된다. 본 논문에서는 착용자의 보행 속도 변화 및 착용자 간 보행 특성 차이에도 강인하게 보행 위상을 추정할 수 있는 LSTM 기반 보행 위상 강건 인식 기술을 개발하였다. 웨어러블 고관절 보조 로봇을 착용한 총 5명의 트레드밀 및 실외 overground의 보행 센서 정보를 바탕으로 학습을 수행하였다. 저속 및 고속 보행을 포함한 다양한 보행 속도에서 정밀한 보행 위상 추정이 가능한 웨어러블 센서 조합을 도출하였고, 보행 위상 인식 정밀성은 5-Fold Cross Validation 기준 RMSE 약 1.68% 수준의 결과를 얻을 수 있었다.

Most of professional baseball teams are not good for business condition because of operation costs in spite of support of mother company. This study measured the relative efficiency and productivity change of the Korean professional baseball teams using DEA model and Malmquist Index for 2006-2008. The main results of this study can be summarized as follows. First, in case of efficiency of CCR for 2006-2008, the number of efficient professional baseball teams(CCR value is one) are two(Doosan Bears, Samsung Lions), two(Doosan Bears, SK Wyberns), two(Lotte Giants, LG Twins) respectively. Second, in case of efficiency of BCC for 2006-2008, the number of efficient professional baseball teams(BCC value is one) are three(Doosan Bears, Samsung Lions, LG Twins ), four(Doosan Bears, SK Wyberns, Samsung Lions, Kia Tigers), four(Lotte Giants, LG Twins, SK Wyberns, Samsung Lions) respectively. Third, average of Malmquist Index representing productivity change for 2006-2008 are 1.0615, 1.0293 respectively. These values mean increase of productivity. Results of this study can be used by inefficient professional baseball teams to improve inefficiency.
