Run expectancy (RE) is the mean number of runs scored from a specific base runner/outs situation of an inning to the end of the inning. Win expectancy (WE) is the probability that a particular team will win the game at a specific game state such as half-inning, score difference, outs, and/or runners on base. In this paper, we derive RE and WE for the Korea Baseball Organization (KBO) League based on six-year data from 2007 to 2012 using a Markov chain model.

Purpose: The purpose of this study was to investigate the status of internet addiction, internet expectancy, and self-efficacy in elementary school students. Method: The study was carried out during the period from June 16 to July 12, 2003. The subjects in the study were 397 elementary students attending four elementary schools in Chungcheongbuk-do and Kyunggi-do. Self-rating questionnaire included general characteristics, internet addiction scale, internet expectancy scale, and self-efficacy scale. Data was analyzed using SPSS/WIN10.0 by unpaired t-test and Pearson corelation coefficient. Result: In this study, the mean score of internet addiction was 20.7. Internet dangerous group was 12.6% and internet addicticted group was 0.3%. The score of internet addiction was significantly different according to parents' concern, aversion to school life and extracurricular lecture. The mean score of internet expectancy was 27.1. The score of Internet expectancy was significantly different according to popularity among friends and easiness of making friends. The mean score of self-efficacy was 55.8. The score of self-efficacy was significantly different according to conversation with parents, enforcement of parents on learning, aversion to school life, aversion to extracurricular lecture, existence of intimate friend, popularity among friends(p=.000), and easiness of making friends. Conclusion: This study showed that prevalence of internet addiction was much lower than expected, but the score of internet addiction and internet expectancy can be different according to parents' concern and relationship with friends. Therefore parents must be concerned about their children and their school lives to prevent internet addiction.

In the midst of the progress of the 4th industrial revolution, the Corona19 Pandemic was forming giant double wave. Companies riding this wave can win, but companies that do not will fall into the wave and struggle. In connection with the 4th industrial revolution, various technologies are emerging and commercialized. At this point, consumers, especially digital natives, who have been with digital since birth, tried to find out what factors affect the intention to use these technologies and which factors have the most important influence. For this purpose, data were collected through a survey on factors affecting the intention to use FinTech technology and AR technology for 150 digital natives in their 20s. Based on this, statistical analysis was conducted and the following results were obtained. As a result of the overall analysis regardless of the type of technology, it was found that performance expectancy, effort expectancy, social influence, and habits have a positive (+) effect on digital natives' intention to use the 4th industrial technology. On the other hand, a significant influence relationship between the facilitating conditions, hedonic motivation and intention to use the 4th industrial technology was not tested. It was found that the influence was greatly influenced by social influence and habits. In the case of FinTech and AR, which were further subdivided into this study, different aspects were revealed as a result of separate analysis. In the case of FinTech technology that emphasizes utilitarian value, performance expectancy, effort expectancy, social influence, and habits had a positive (+) effect on intention to use. It was found that the influence was greatly influenced by habits and social influence. In the case of AR, which emphasizes the hedonic value, all the variables adopted in this study had a positive (+) effect on the intention to use the technology. It was found that hedonic motivation and social influence had a great influence. Combining the results of the analysis, social influence was found to be an important influence variable regardless of the type of 4th industrial technology. FinTech technologies such as mobile banking, where services are becoming more common, are habits, and in the case of AR, which has not yet been universalized and is provided mainly for entertainment, hedonic motivation was found to be an important factor. This study was able to present academic and practical implications based on the above confirmation of factors affecting digital natives' acceptance and use of the 4th industry technology.

Purpose: The purpose of this study was to identify change in the exercise behavior and to identify factors influencing long-term adherence to aquatic exercise in patients with arthritis as a follow-up study after five years. Method: Baseline data had been collected using a structured interview 6 months after participants completed the aquatic exercise educational program. This second follow-up data collection included 133 participants from the original baseline study and was done 5 years after the original baseline study. Data was analyzed using SPSS 16 Win program. Results: The stage of change for the participants was as follows: Precontemplation (44.3%), Contemplation (24.1%), Preparation (3.0%), Action (0%) and Maintenance (adherence, 28.6%). The adherers (N=38) had significantly higher scores than non-adherers (N=91) in self-efficacy, outcome expectancy, group coherence and self-evaluation, and significantly lower scores in barriers to exercise. In logistic regression analysis, self-efficacy, group cohesion, barriers to exercise and self-evaluation were associated with exercise adherence (Chi Square=17.14, p=.002). Group cohesion (OR=2.5871, 95% CI=1.094-6.113, p= .030) was the most important factor. Conclusion: Self-efficacy, group cohesion, barriers to exercise and self-evaluation need to be considered in planning exercise programs to improve exercise adherence.

Conventional funding system for the university research projects is limited to a grant or subsidy type funding method which does not require an obligation of refund. Such a funding system is known as ideal one for the university research activities which in general is not a profit oriented activities. It is considered ideal in a sense that nonprofit oriented research activities gives more emphasis on creativity than on efficiency or practical value. A venture- business-start-up research activity can not be considered as a pure nonprofit oriented activities. It clearly gives more emphasis on efficiency and practical value than on creativity Recently a large portion of the venture-business-start-up research activities are carried out in the universities. When a conventional research funding system is applied to such a new type of research activities, it turned out that the success rate is much lower than expectancy. This is why a new and differentiated funding system is sought for such a new type of research activities. A funding system of loan type for a venture-business-start-up research activities is proposed herewith. A loan system naturally requires a pay back after the successful start up of the venture business. This loan system nay be considered that a business concept is grafted on a conventional funding system for the university research activities. This means that a rather loose or generous terms and conditions of the money loan case is introduced into this funding system to remedy the short comings of the intrinsic nonprofit nature of the university research activities. The point is how to improve the success rate and how to reduce the undesirable aspect of the conventional university research activities when it is practiced with the new type of research activities. After one and half year of practicing with the new funding system. it can not be asserted that a definitely positive results could be obtained. but a trend of desirable aspects could be observed such as low drop out rate. project selection efficiency, higher sense of responsibility. etc.
