  • Organizations must seek change in order to adapt to environmental changes and achieve better performance. However, despite this obvious statement, empirical analysis has been almost non-existent due to the difficulty of manipulating organizational performance or change. In this study, we overcame these limitations and analyzed the causes and effects of organizational change by assuming a professional sports team as a venture company, which is relatively easy to objectively measure and evaluate organizational change or performance. We systematically collected and preprocessed traditional and advanced metrics of National Basketball Association (NBA) statistics along with preprocessed trade data from eight years of regular seasons (2014~2015-2021~2022) to analyze our research model. Assessment of process macro model 7 derives the following empirical result. The results of the empirical analysis depict that NBA teams with low organizational performance in the previous season are more likely to make organizational changes through player trades to improve performance. Into the bargain player trades mediate the static relationship between the winning percentage in the previous season and the winning percentage in the current season. However, the indirect effect of a team's previous season's performance on player trades appears to vary depending on the current situations and context of each NBA team. Teams that made the playoffs in the previous season tend to make fewer trades than teams that did not and the previous season's performance is highly correlated with the current season's performance. On the other hand, teams that did not make the playoffs in the previous season tend to make a relatively larger amount of player trades in total, and the mediating effect of trades vanishes in this case. In other words, teams that did not make the playoffs in the previous season experience a larger change in performance due to trades than teams that made the playoffs, even if they achieved the same winning percentage. This empirical analysis of the inverse relationship between organizational change and the performance of professional sports teams has both theoretical and practical implications in the field of sports industry and management by analyzing the fundamentals of organizational change and the performance of professional sports teams.

  • The objective of this study is to verify the effects of Moosim-Gi-Gong Doinbeop on low back pain targeting low back pain patients hospitalized in Korean medicine hospitals. For the study, 44 adult female and male patients hospitalized with low back pain at M Korean Medicine Hospital and H Korean Medicine Hospital located in Gimpo, Gyeonggi Province were recruited. The subjects had a temperature difference between left and right 湧泉(KI1) of over 0.5℃ through infrared thermographic imaging, and 23 of them were classified in the control group for retrospective analysis based on the test records. Infrared thermographic imaging, X-ray pelvic AP view - standing position, a sit-and-reach test and a VAS survey were employed for detection, and IBM SPSS Statistics 24 for the statistical process. The results were rounded down to three decimal places as in an average±standard deviation, and the significance level was 0.05 to be evaluated significant if p<0.05. The result of the study is as follows: 1. In the comparison between before and after conducting Moosim-Gi-Gong Doinbeop, the meaningful difference was shown in the experimental group in all indicators. But Indicators except for the temperature difference between right and left 湧泉(KI1)(difference between before and after) and In displaced pelvic correction indicators on the X-ray showed a significant difference in the control group. 2. As for the variation widths of the experimental group and the control group, the former showed significant temperature differences between 印堂(EX-HN3) and 關元(CV4) and right and left 湧泉(KI1); difference variations of anteflexion; and changes in PI and In displacement on the X-ray. 3. As for changes in the experimental group according to demographic characteristics, gender, age and degree of obesity did not show significant differences in all indicators. However, those who experienced back pain for more than six months in the experimental group showed the biggest body temperature differences between 印堂(EX-HN3) and 關元(CV4), while other indicators had no significant difference. As a result, patients who received Korean medicine treatment showed relieved back pain and improvement in pelvic correction and sports activity; however, those who got Moosim-Gi-Gong Doinbeop together showed more clearer improvement effects in pelvic correction and sports activity.

  • This study analyzed the difficulty of scoring in different match situations in relation to which competitor scored first. The study analyzed the data from the 2022 Guadalajara World Taekwondo Championships. The analysis was performed for two separate weight classes: lightweight and heavyweight. Four game content variables were used: whether the athlete scored first, attack type, attack area, and game situation. Descriptive statistics, the Rasch model, and discrimination function questions were applied for data processing. SPSS and Winsteps were used for the statistical analysis, and the statistical significance level was set at 0.05. Consequently, in the lightweight class, the scoring frequency of the first scorer was high for all the game variables. In the heavyweight class, the scoring frequency for the first scorer was high for the attack type and attack area. By contrast, those who did not score first were more frequently found to be in a loss situation. By analyzing the scoring difficulties in different match situations based on whether the competitor scored first, the athletes who scored first in attack type most easily scored first. In losing situations, the athletes who scored first in attack area scored most easily, whereas those who did not score first scored most easily in body and match situations. For the heavyweight class, those who scored first in terms of attack type, counter-attack, and attack area scored the most easily while winning in body and match situations.

Data were gathered from the Statistics Korea Life Time Surveys from 2004(y1) and 2019(y2) (n=2,697). Life time was composed of three types(inevitable time, compulsory time, and leisure time) and leisure time was categorized into 11 activities(voluntarism, participation, social relationships, religion, rituals, culture and tourism, sports, game and play, media, rest, and others) to investigate gender differences and time effects.

Second, fathers spent more time on 10 leisure activities except religion in y1, and on all activities than mothers in y2. In y2, less time on three activities(social relationships, rituals, and media) for both fathers and mothers, less time on religion for mothers only, more time on two activities(participation, game and play) for both groups were spent than y1. Third, in the regression analysis of fathers' and mothers' leisure time on three leisure activities(sports, game and play, and media) with a distinct pattern from leisure time for adult group between y1 and y2, socioeconomic variables and lifetime variables showed different effects by gender and waves.
