In this paper, we suggest the Deep Neural Network Model System for predicting results of the match of 'League of Legends (LOL).' The model utilized approximately 26,000 matches of the LOL game and Keras of Tensorflow. It performed an accuracy of 93.75% without overfitting disadvantage in predicting the '2020 League of Legends Worlds Championship' utilizing the real data in the middle of the game. It employed functions of Sigmoid, Relu and Logcosh, for better performance. The experiments found that the four variables largely affected the accuracy of predicting the match --- 'Dragon Gap', 'Level Gap', 'Blue Rift Heralds', and 'Tower Kills Gap,' and ordinary users can also use the model to help develop game strategies by focusing on four elements. Furthermore, the model can be applied to predicting the match of E-sports professional leagues around the world and to the useful training indicators for professional teams, contributing to vitalization of E-sports.
The aim of this study is to explore the educational experience of nursing students after designing an action learning class suitable for basic nursing science class and applying it.

PURPOSE: The purpose of this study was to investigate the effects of a group exercise program with competitive games on balance in chronic stroke patients. METHODS: The subjects were chronic stroke patients living at home after their discharge from the hospital. A total of 32 subjects were divided into two groups. The experimental group performed a group exercise program with competitive games, and the control group performed individual exercises. The exercise program duration was one hour, and it comprised 10 minutes of stretching, 40 minutes of the main exercise, and 10 minutes of stretching at the end. The experimental group was divided into two teams of 8 players each and played competitive games (transfer a gym ball to another person, relay 10 m walking and return, transfer an object to the next person using both arms while sitting). The control group performed an arm/trunk exercise for 15 minutes and gait training for 25 minutes. These exercises were conducted twice a week (4 weeks). The Berg Balance Scale (BBS) and timed up-and-go (TUG) tests were performed to confirm the change in balance. RESULTS: In the experimental group, BBS showed a significant increase (p < .05) and TUG showed a significant decrease (p < .05). In the control group, there was no statistically significant change in the BBS. However, the TUG showed a significant decrease (p < .05). The BBS and TUG both showed statistically significant differences (p < .05) in the between-group comparison of the change in pre-post intervention values. CONCLUSION: A group exercise program with competitive games to improve the balance ability for fall prevention in chronic stroke patients could be used as a good intervention method.

Background and objective: This study was conducted to investigate the effect of an agro-healing program on the relationship satisfaction and emotional change between parents and children. Methods: We sent an official letter to D Office of Education with information and recruitment for the agro-healing program. Then D Office of Education has sent the official letter to elementary schools under the jurisdiction to recruit parents who were willing to participate in the programs with their children. The subjects were recruited by order of application, and 27 families participated, but 20 parent-child teams who attended all sessions and fully participated in the program were ultimately selected. From October 12 to November 16, 2019, a total of 6 sessions of the programs were held once a week at a care farm in Gyeongsangbuk-do. In the morning, they participated in a program that utilizes the resources of plants and animals in the care farm, and later participated in an indoor horticultural program in the afternoon. Results: In the parent-child relationship satisfaction test, it was found that communication was significantly increased after participating in the agro-healing program (p = .047). There were no statistically significant changes in the sentence completion tests written by the children, but their potential perception or attitude towards their parents changed more positively than before according to the content of the sentences. Conclusion: The agro-healing program could strengthen the relationship between parent and child by improving the parent-child relationship satisfaction and children's emotional attitude towards their parent.

This study analyzed the relationship between efficient pitchers and teams advancing to the postseason in Korean professional baseball through DEA. A total of 1,133 pitchers who threw more than one inning from the 2014 season to the 2018 season were selected for this study. For DEA analysis, input variables were selected as annual salary and inning output variables as Wins, Saves, and Holds and the number of efficient pitchers for each season was classified using the input-oriented BCC model. After that, it was divided into two groups based on joining the postseason or not, and the number of efficient pitchers was compared through a prop test. As a result of the analysis, the groups that advanced to the postseason in the rest of the season except for the 2014 and 2017 seasons had more efficient pitchers. Considering that the 2014 season recorded the highest WAR (Wins Above Replacement) at 183.56 compared to other seasons, most pitchers threw well, and in the 2017 season, they made more mistakes in pitching than in other seasons, but they performed well in batters. The results of this study have expanded the research field using efficiency analysis in professional baseball and can be used as useful data for practical research.
An educator may utilize various pedagogies such as hands-on practice, practicum, and project-based learning to enhance a student's competency. Among various pedagogies, project-based learning is one of the well-known pedagogies that may provide similar on-the-job experience. In general, an educator may divide the students into small groups and assign tasks to check students' cooperation skills and achievements during project-based learning. However, an educator may experience difficulties operating project-based learning due to the COVID-19 pandemic. Most of the team activities are done in non-face-to-face meetings, and as a consequence, the educator may not find an underachieving team easily and cannot intervene appropriately. This study introduces a rigorous analysis method to evaluate team activities to analyze individual students' participation and contributions. First, this study develops evaluation rubrics by conducting questionnaires to professors and students to find an appropriate weight value for the evaluation scale. Then, this research introduces an analysis environment to evaluate students automatically. The analysis environment collects dialog data from social network services and measures interactions among students in a team. After measuring interactions, the environment generates a report to visualize the team activities. We applied the proposed method and environment to the capstone design course to show the effectiveness of the method and environment. Based on the case study, the environment showed that the analysis method could easily indicate the teams' activities and check the level of participation.
Purpose: The purpose of this study is to examine the factors affecting the intention to use online collaboration tools for non-face-to-face educational environment in the perspective of the learners. Methods: For empirical analysis, the survey of this study was administered with data that were limited to experienced learners using online collaboration tools such as Google Docs, Allo, Padlet, and Slido in online education environments such as Zoom, Webex, MS Teams, etc. and valid 400 data were analyzed by SPSS(ver 22.0) and R(ver 4.1.0) program package. Results: The results of empirical analysis showed that performance expectancy were found to have an effect on reliability of system quality, empathy of service quality, playfulness and informativity of content quality among the characteristics of online collaboration tools. On the other hand, it was found that the security of system quality, responsiveness of service quality, and extroversion of user personality characteristics did not affect. It was analyzed that playfulness had the greatest positive effect, followed by informativity, empathy, and reliability. Among the characteristics of online collaboration tools, it was found that the reliability and security of system quality and informativity of content quality had an effect on the effort expectancy. It was analyzed that informativity has the greatest influence, followed by security and reliability. Conclusion: This study is meaningful in that it examines the perspectives of users and learners, who can be said to be the end customers of online collaboration tools. Based on the results of this study, it is expected that not only platform operators that provide online collaborative tools, but also providers that use online collaboration tools will have a significant impact on the development of edutech and infrastructure in the educational environment.
This study is a plan on the way to strengthen the survival ability by increasing the use time of air respirator by applying emergency breathing method in the situation where firefighter has to wait for RIT (Rapid Intervention Teams) because it is impossible to escape by himself or emergency escape during isolation during field activities. The research procedure first drew problems by conducting a survey on fire fighters under the Seoul Fire and Disaster Headquarters, and conducted an experiment to compare normal breathing and emergency breathing with 20 members of the Seoul 119 Special Rescue Team, and suggested emergency breathing method and training process modeling that can be applied to each field situation based on the data obtained. The experiment was conducted over 9 weeks, and it was divided into three categories: field activity situation, movement (emergency escape assumption) situation, and place (assume waiting for RIT). In the field activity situation experiment, it was confirmed that the application of skip breathing method was appropriate and the use time of air respirator increased about 1.6 ~ 1.9 times. In the moving situation or the in-situ situation, wheel breathing method was appropriate and the use time of air respirator increased about 1.6 ~ 2.4 times. However, when conducting intense activities in the field activity situation, it is recommended to use it limitedly because it is difficult to apply the emergency breathing method. If emergency breathing is not clearly learned in the body, it is difficult to use in the field, so I think systematic and continuous training is necessary. This study suggests that the application of emergency breathing method is effective enough to strengthen the survival ability of firefighters in the field.
