Recently, attempts have been made to use data to operate games, seasons, and teams in professional baseball. Therefore, in this study, we collected baseball game records and analyzed the relationship between on-base rate and pitching count induction, and this was defined as the third record for non-game factors such as discomfort index, which includes the weather application data. When the discomfort index was over 75, the pitcher's induction of pitching was high, and when the discomfort index was less than 69.9, the on-base rate was high, but when the discomfort index was 70 or more and less than 75, the batter's on-base performance was the lowest. Through the results of the study, it could be inferred that the discomfort index, the batter's on-base rate, and the number of induction pitches are related, and that it is highly likely to be related to the pitcher's performance. Through this study, we could see the possibility of defining a cumulative/ratio record defined as the primary record and a saver metric defined as the secondary record, and a third, tertiary record linking data outside the game.

As the Korean College scholastic Ability Test (CSAT) has been implemented for 17 years since 1994, it is becoming more and more difficult to make new items that haven't been previously used to measure students' thinking ability. Therefore, it is necessary to keep conducting research on making new test items that can measure students' scholastic ability reliably. For this reason, multiple choice items on the Japanese university entrance exam, which is a Japanese National Center Test for University Admissions (NCTUA) equivalent of CSAT, were analyzed in order to draw implications for CSAT item development. In this study, we analyzed the Japanese NCTUA administered in January 2009 to investigate the structure of its science test. We also analyzed the NCTUA items by the domains of contents and behaviors, and tried to predict item difficulty from the perspective of Korean applicants. Major findings are as follows: Most NCTUA items measure understanding knowledge or low level thinking ability. Also the alloted time for each item is longer than CSAT. The number of test items, and the number of choice and alloted points for each item are diverse, unlike CSAT. The number of items using real-life materials are much more, but the items are not rigorous in sentence expression compared to CSAT. And the difference of difficulty level among science tests were larger with reference to CSAT. Also science score is required for most applicants regardless whether they are taking liberal arts or going onto the science track.

Objectives: Smokers who had failed to quit smoking were frequently reported that life stress mostly interrupted their abstention. Stress vulnerability model for smoking cessation has been considered, and most of contemporary smoking cessation programs help smokers develop coping strategies for stressful situations. This study aims to investigate the appropriate coping styles for stress of abstention from smoking. The result of investigating the relationship between abstention following smoking cessation program and coping styles would suggest useful information for those who want to stop smoking and health practitioners who help them. Methods: Participants were 69 smokers (62 males, 7 females) participated in a hospitalized smoking cessation program, whose mean age was 44.89 (SD=9.61). Participants took medical test and completed questionnaires and psychological tests including: Fagerstrom Test for Nicotine Dependence and Multidimensional Coping Scale. To identify participants' abstention, researchers followed them for 2 years. To identify whether abstained or not and encourage them to abstain, researchers called them on the telephone once a week for 3 months. After 3 months, they were contacted every other week till 6 months passed since they left smoking cessation program. And they were contacted once a month for other 18months. Researchers also contacted their family to identify their abstention. Data Mining Decision Tree was performed with 37 variables (13 variables for the coping styles and 24 smoking-related variables) by Answer Tree 3.0v Results: Forty four (63.8%) out of sixty nine for 2 weeks, 34 (49.3%) for 6 months, 25 (36.2%) abstained for 1 year, and 22 (31.9%) abstained for 2 years. Participants of this study abstained average of 286.77 days from smoking. Included variables of a Decision Tree model for this study were positive interpretation, emotional expression, self-criticism, restraint and emotional social support seeking. Decision Tree model showed that those (n=9) who did not interpret positively (<=7.5) and criticized themselves (>6.5) abstained 23 days only, while those (n=9) who interpreted positively (>7.5), expressed their emotion freely (>6.5), and sought social support actively (>11.5) abstained 730 days, till last day of the investigation. Conclusion: The results of this study showed that certain coping styles such as positive interpretation, emotional expression, self-criticism, restraint and emotional social support seeking were important factors for long-term abstention from smoking. These findings reiterate the role of stress for abstention from smoking and suggest a model of coping styles for successful abstention from smoking. Despite of limitation of this study, it might help smokers who want to stop smoking and health practitioners who help them.

Objectives: The purpose of the study is to investigate and analyzed the current status of a dental hygiene curriculum according to the dental hygienist competency. Methods: The study subjects were 59 courses in the department of dental hygiene in G University from April 1 to May 30, 2015. Except for liberal arts, 51 courses were finally selected and analyzed for the relationship between the curriculum and competency. For each course, systematic reviews were made by subject name, core competency, achievement goals, lecture hours, weekly themes, and learning goals. Three experts in the dental hygiene evaluated and analyzed the association of competency and goals. Results: Each course was operated by the goal from one to twenty two competencies of dental hygiene. Achieving one item of competency in a course required 13 hours on the average from minimum 2 hours to maximum 30 hours. More than 20 courses were operated and more than 900 hours were necessary for achieving the competency. The competency included the contents of 'Be able to utilize basic medical and dental knowledge in dental hygiene care and patient care' among the dental hygiene competencies. Conclusions: Competency based dental hygiene education will provide theoretical background for defining the identity of dental hygienist as a health care worker and to encourage professionals who contribute to the recognition of healthy society. Further research should be continued for improving the competency-based dental hygiene curriculum and education methods for implementing the curriculum within the paradigm of health care services.

This study redesigned the Korean speaking classes to foreign undergraduate students as flipped learning classes and verified their effect on speaking-related emotional variables. In addition, international students' perceptions of what experiences are needed to improve speaking efficacy in Korean were examined. For this purpose, the 'Creative speaking' subject for freshmen was redesigned to flipped learning class and operated for one semester. To analyze the effect of speech-related emotions, a paired t-test was conducted on 26 foreign students' pre-post scores of speech efficacy and anxiety. Also awareness of experiences needed to improve speech efficacy was surveyed and content analysis was conducted. As the result, the speaking efficacy of students after flipped-learning has been significantly improved. This means that flipped learning classes for the Korean speaking are effective for the positive emotions of foreign students speaking Korean. In addition, international students perceived that Korean speaking efficacy can be improved by practicing speaking in Korean, learning with Korean colleagues. Based on these results, several discussions and suggestions were presented.

Since socioscientific issues (SSI) reflect various characteristics of new technologies designed to meet the incessant human needs in the contemporary society, this study explores the feasibility of adapting nature of technology (NOT) to analyze students' socioscientific decision-making. To achieve the aim, forty-five college students enrolled in a liberal arts course on science and technology studies participated in the study and responded to a GMO (golden rice) scenario in a written form. Four major viewpoints were identified from their writing: 1) is the technological artifact able to solve a societal problem?, 2) are there some alternatives to solve the societal problem?, 3) what kinds of side effects or flaws could turn up during distribution and consumption of the technological artifact?, and 4) can we cope with the technological uncertainty? We revisited the viewpoints within the NOT framework (technology as a 'fix,' cultural context and role of values, technological trade-offs, technology as a system, and technological progression). As a result, unlike NOS, NOT were quite explicitly represented in their decision-making and students' level of understanding on NOT varied. It indicates that NOT can be a promising construct for cultivating informed SSI decision-making.

This study investigates how the emotion-based learning motivation enhancement program influences learning motivation and social support of college students. The developed final program consists of Learning Motivation I, Learning Coaching, and Learning Motivation II, which has 12 sessions. In each session, every student was guided to have reflection time by writing self-evaluation and reflection paper. The participants were 38 students majoring in engineering at K-college located in G city who took one liberal arts subject based on psychology during the 1st semester in 2016 and who were divided into an experimental group (19 students) and a control group (19 students) by non-probability sampling method. In the experimental group, emotion-based learning motivation enhancement program was totally processed 12 times, one class in a week, by one main lecturer and one assistant lecturer. For data analysis, independent sample t-tests, paired samples t-tests, and review analysis were conducted. The study results are as follows. First, the experimental group participating in emotion-based learning motivation enhancement program had more significant differences in learning motivation, and both self-confidence and self-contentment among sub-components than the control group. Second, the experimental group had no significant differences in social support, compared with the control group. The impression writing analysis of the experimental group showed that this program affected learning motivation and social support. Lastly, the study discussions and implications are described.

This study was conducted to investigate effects of 12 weeks of combined exercise training with blood flow restriction (BFR) on body composition (weight, %body fat, lean body mass, body mass index (BMI)) and cardiovascular responses (brachial-ankle pulse wave velocity (ba PWV) and ankle-brachial index (ABI)) in elderly women. Participants (N = 43, Females) were randomly assigned into a combined exercise with BFR (n = 14, BFR), only combined exercise (n =14, EX) or non-exercise control group (n = 15, CON). Two-way repeated measures ANOVA with contrast testing was utilized for data analysis. Alpha was set at p < 0.05. Body composition (weight, %body fat, BMI) in BFR was significantly changed, and %body fat in EX was significantly decreased, but there was no change in the CON. In addition, the right and left ba PWV values in the BFR were significantly decreased, while only the left side ba PWV in EX was significantly decreased and there was no change in the CON. Moreover, the % change and effect size of most variables in the BFR were higher than the EX. Taken together, the results indicate that even though BFR and EX groups performed the same combined exercise training, BFR had additional stimulations of the sympathetic nerve system due to blood flow restriction. Thus, BFR training is more beneficial and has greater effects on body composition and cardiovascular responses in elderly females.

The purpose of this descriptive correlational study was to explore the effect of knowledge of evidence-based practice (K-EBP) and organizational culture on the innovation behavior of university librarians in South Korea. The structured survey questionnaire consisted of four sections and 60 items. The four sections were concerned with K-EBP, organizational culture, innovation behavior, and EBP-related activities and demographic. The respondents were librarians working in 101 university libraries in South Korea. The results of this study were as follows. First, K-EBP indicated that the respondents had excellent practical skills, but their ability to appraise critically, apply knowledge and to conduct research was weak. Second, the questionnaire scores for K-EBP were significantly positively correlated with those for organizational culture and innovation behavior. Higher K-EBP scores corresponded to higher scores for relation-, innovation-, and task-oriented organizational culture. Third, K-EBP outcomes differed significantly by age group, education level, employment type, job title/seniority, reading of academic journal articles, and attendance at conferences. Organizational culture differed significantly with age. Innovation differed significantly with both age and conference attendance. Fourth, in the hierarchical multiple regression analysis, factors predicting K-EBP scores were education level and reading academic journals. Fifth, the multiple regression analysis identifying factors predicting innovation revealed statistically significant regression coefficients for overall K-EBP and for innovation- and hierarchy-oriented organizational culture. The regression coefficient for perception of a hierarchy-oriented organizational culture was negative. To promote innovation behavior of librarians, we need to foster an innovative organizational culture characterized by communication and cooperation, and improve the ability of librarians to engage in EBP. Educational programs that promote librarian engagement in research-related activities are needed.

The purpose of this study is to examine the mediating effect of physical activity in the relationship between generalized anxiety disorder and overdependence on smartphones in adolescents. To find a way for solving the problems caused by the over-use of smartphones during adolescence, we tried to find the importance of a health promotion program through physical activities. For the purpose of the study, the 2020 Youth Health Behavior Survey data conducted by the Ministry of Education, the Ministry of Health and Welfare, and the Korea Centers for Disease Control and Prevention were used as analysis data for this study. As a result of the study, firstly, generalized anxiety disorder has a negative (-) relationship with physical activity, and physical activity also has a negative (-) relationship with overdependence on smartphones. Secondly, as a result of analyzing the mediating effect of physical activity in the relationship between generalized anxiety disorder and smartphone overdependence experience, the physical activity was found to be a significant factor. Thirdly, it was confirmed that the physical activity has a partial mediating effect in the relationship between generalized anxiety disorder and smartphone overdependence experience. Increasing physical activity through team sports rather than individual sports may help reduce smartphone use.
