Professional baseball is one of the spectator sports that has been loved for a long time by the citizens as a recreational activity since its establishment in 1982, and has been playing pivotal role as a national sport. However, there has been decline in the number of audiences since 2019. Hence, this research paper aimed to provide strategic direction for planning and improvement of professional baseball stadiums by applying the concept of servicescape. In this research, five key factors of servicescape that affects players performance and the level of immersion of spectators were derived through literature review, and based on these key factors, case study analysis were carried out for 51 domestic and foreign baseball stadiums while focusing on the factors derived. Domestic baseball stadiums highly concentrate on spectatorship without effectively responding to change in spectators demand and its effective use of space rather than baseball games. As in foreign cases, it is critical to modify mangement process and planning direction, and improve policies while perceiving baseball stadium as recreational and cultural space.

This study attempted to investigate the effect of competitive anxiety on injury psychology according to the athletic career of tennis athletes at Chinese universities. To study the method, 208 athletes enrolled in a four-year university (0 university, 0 university) located in A City, Hanam Province, were surveyed for a total of three weeks from the end of January to the beginning of February 2023. To verify the research model, frequency analysis, exploratory factor analysis, reliability analysis, and correlation analysis were conducted using SPSS Statistics 25. And independent sample t-test and one-way ANOVA were conducted to find out the differences in variables according to general characteristics, and multiple regression analysis was conducted to verify hypotheses through the concept of measurement. As a result of the study, first, it was found that there was a significant difference in the athletic career of tennis athletes at West China University. Second, the non-standardized coefficient of competition anxiety was found to have a positive (+) effect on exercise weaponry. Third, the non-standardized coefficient of competition anxiety was found to have a positive (+) effect on anxiety and anxiety. Therefore, it was found that other competitive anxiety in the exercise career had an effect on injury psychology. Since competition anxiety according to the athletic career of tennis athletes at Chinese universities affects injury psychology, it suggests that a psychological program that can control competition anxiety and injury psychology of athletes should be developed and introduced to athletes.

Compared to men, women experience difficulties in fund-raising, which can be a fundamental impediment to the success of women entrepreneurs. In this study, we examine whether is a difference between genders in the initial funding performance of start-up companies and confirm whether there are differences in organizational factors and entrepreneur factors that affect the initial funding performance. Data were collected through a survey of technology-based start-up companies located in the metropolitan area, and 287 companies were used for hypothesis analysis. The results reveal that there was a significant difference between genders in the investment attraction performance of early-stage entrepreneurs. In addition, as a result of the split-group regression analysis, it was found that in the case of men, firm age, early firm size, starting capital, engineering major had a significant effect on men. However, in the case of the women's group, it was confirmed that all the variables related to the organizational factors and entrepreneur factors were not significant. This study indirectly suggests that prejudices such as gender role stereotypes actually affect economic activities related to investment attraction activities.

This investigation was carried out to find the effects of silkworm rearing technique on the harvesting amounts. In spring and autumn of 1971, 14 silkworm rearing farmers at Botong Ri and Youngsoo Ri, Chongnam Myun, Hwaseung Kun, Kyunggi Do in Korea were selected as sample farmers. They were devided into two groups, high productivity group and low productivity group according to their harvesting amounts per box of silkworm eggs in 1970. The high productivity group represents the farmer who produced above average harvesting amounts per box, and the low group represents below average group. In this investigation, all farmers were adjusted to share uniform rearing condition with even mulberry leaves. Under this uniform condition, the effects of rearing techniques on the harvesting amounts per box of silkworm eggs and the effects of rearing condition on the harvesting amounts were inferred. Results obtained are as fellows; (1) Measuring from the 14 sample farmers, the effect of rearing technique on the harvesting amounts per box covers 15% of farmers in spring rearing season but 33% in autumn season. (2) Measuring from these sample farmers, the effects of the nutrition condition is less than 56% in spring rearing season but less than 69% in autumn, and it can be concluded that these effects include the effect of climate factor. (3) In the low productivity group. the most important facto. affecting the low productivity is non-disinfection of rearing environment.

This study focused on verifying the identification of freshwater fish species in Korea using Environmental DNA (eDNA) technique. The research of DNA is increasing in the field of ecology, since this is more sensitive of identify rather than traditional investigation method. Which is difficult to detect species hidden in water and be easily influenced by diverse factors (sites, bad weather, researchers and so on). We applied the pilot test in aquarium (Freshwater Fish Ecological Learning Center in Yangpyeong, Gyeonggi Do), where freshwater fish species are inhabits. We conducted to sampling and analyzing the sixteen water samples (50 species from 7 orders and 13 families) using MiFish primer set. The results showed that 45 species (90%) was investigated by eDNA. It highlight that eDNA with universal primer is possible to detect freshwater fish species of Korean. However, the errors on species identification seems to be caused by the primer that be not suited perfectly and the pollution such as aquarium, sampling collectors.

The purpose of this study was to examine the factors influencing the decision to get implant treatment at dental clinic. The subjects in this study were 321 patients at dental hospitals and clinics. Andersen model in which predisposing variables, enabling variables and need variables were suggested as independent variables was used. The implant decision making was selected as a dependent variable in the model. Using logistic regression analysis, we found statistically significant effects of three independent variables: 1) class, 2) satisfaction with the facility; 3) familiarity with others received implant treatment. Those with the middle or high class background were more likely to take implant treatment. Those who were satisfied with clinic facility were more likely to take implant treatment. Those who were familiar with others received implant treatment were more likely to take implant treatment. This result implies the importance of opinion of others were received the same treatment. Hence viral marketing effort is required even in dental care field.
