Bicycle fitting used to depend on empirical adherence of bicycle Peter and intuitive judgment by hand, but recent developments in industry and the Fourth Industrial Revolution have continuously developed other related tools that can be applied to bicycle fitting. Depending on these circumstances, bicycle fitting technology is also developing, and due to the difficulty of the technicians, there is a limit to popularizing. The Bicycle Integrated Fitting System has the need for this study to make these problems easy for anyone to operate by the system of manual. The purpose of this study is to examine the methods of physical sizing among the various stages of developing these systems. Accurate physical measurements can improve the efficiency of bicycle riding and minimize the injury of bicycle risers issued by incorrect fittings. Thus, in this study, physical measurement methods for bicycle fitting were derived by body region and applied to the post-measurement fitting as well as the location and method of measurement. It has prepared a basis for establishing a core database for physical measurement of development of integrated bicycle fitting system. Research was conducted to enhance understanding and utilization of users after system development and results were derived for the purpose of the study. Research was conducted to establish a database for the development of a bicycle integrated fitting system, and future research on bicycle fitting methods, application of the system, and hardware development should be carried out.

As the industry develops and quality of life increases, the concept of leisure is also changing. Bicycling is a healthy sport for exercising while enjoying nature, facilitating the enjoyment of a healthy life. As a result, the awareness surrounding bicycles has increased, and so has the interest in lighter and more luxurious carbon bikes. The number of domestic companies producing carbon bicycles frames is nil. In this study, we analyze the frames of existing foreign brands and analyze the deformation and stress concentration area according to the load of the frame, using the finite element analysis. In addition, we set up the range of stiffness based on the content of the structural analysis, to localize the carbon bicycle frame and famous foreign products, and compare the prototype with the stiffness by using bicycle molds for track races.

언젠가 끝이 날 줄 알았던 코로나19는 이제 '언택트 시대'라는 우리의 삶과 일상이 되었다. 급변된 삶의 패턴에 적응하기 위한 스트레스와 우울감은 남녀노소 구분 없이 상당하며, 이를 해소할 수 있는 방법과 공간들이 점차 줄어들고 있음에 우리는 정신적, 육체적 건강을 우려하지 않을 수 없다. 그저 많은 여가 활동 중 하나의 종목이었던 콘솔게임이 빛을 발하는 시점이다. 이웃주민들과 축제를 열고, 여행을 다니며 모험을 떠나 땀이 나도록 운동을 하게 된다. 본 논문에서는 대표적인 콘솔게임 닌텐도에 대해 알아보고, 우리나라 게임시장이 국민의 신체적, 정신적 건강을 위해 앞으로 주목해야 할 방향성에 대해 알아보고자 한다.

In 2012, fishes caught by three-side fyke net in the coastal waters of Jedo were assessed for species composition and seasonal fluctuation in their abundance. The fish were caught at two research stations (St.) and were found to comprise 53 species, 39 families, and 9 orders. The dominant species were Takifugu niphobles, Lateolabrax maculatus, and Acanthopagrus schlegelii. To gain a measure of their biodiversity, all the species were assessed for their number, richness, diversity, evenness, and dominance. The highest and lowest number of total caught fish individuals was recorded in summer and winter, respectively. The diversity index was the highest in summer and lowest in winter. The evenness index was the highest in summer and lowest in spring. The richness index was highest in summer and lowest in winter. Furthermore, the dominance index was highest in spring and lowest in autumn.

Purpose: This study aims to utilize geographic data to analyze how various retail formats of large-scale stores around the traditional market affect the performance of the traditional market in Seoul, Korea. Research design, data, and methodology: The two types of catchment areas were demarcated (circle of 1km radius and Thiessen polygon) for each traditional market, and the large-scale stores located within each catchment area were identified for 153 traditional markets in Seoul, Korea. Additionally, multiple regression analysis was utilized. Results: The results revealed that the influence on the performance of the traditional markets were different depending on the retail format of the large-scale stores. Large discount stores were found to have a negative effect on the sales and the visitors of traditional markets, whereas complex shopping malls and department stores had a positive effect on the traditional markets. Conclusions: As a result of the differences in the retail format such as product categories and leisure functions, the impact of some large-scale stores on the traditional market may have a greater agglomeration effect than the consumer churn effect. Therefore, it is suggested that in the regulation of these large-scale stores, the differences in retail format should be considered for the future.

Objective: Thoroughbred horses have been bred exclusively for racing in England for a long time. Additionally, because horse racing is a global sport, a healthy leisure activity for ordinary citizens, and a high-value business, systematic racehorse breeding at the population level is a requirement for continuous industrial development. Therefore, we established genomic evaluation system (using prize money as horse racing traits) to produce spirited, agile, and strong racing horse population Methods: We used phenotypic data from 25,061 Thoroughbred horses (all registered individuals in Korea) that competed in races between 1994 and 2019 at the Korea Racing Authority and constructed pedigree structures. We quantified the improvement in racehorse breeding output by year in Korea, and this aided in the establishment of a high-level horse-fill industry. Results: We found that pedigree-based best linear unbiased prediction method improved the racing performance of the Thoroughbred population with high accuracy, making it possible to construct an excellent Thoroughbred racehorse population in Korea. Conclusion: This study could be used to develop an efficient breeding program at the population level for Korean Thoroughbred racehorse populations as well as others.

Purpose: This study aims to fill the existing gap in the existing literature by investigating the mediating effect of psychological empowerment between leadership and motivation for workers at retail stores, and to extend the previous research to determine the preferences of the researchers and practitioners in leadership and employee motivation in retail through a systematic approach. Research design, data and methodology: This study used a systematic approach to the mediation effect of psychological empowerment on the relationship between leadership and employee motivation in retail stores. To ensure completeness, systematization, and transparency, the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach was applied. Results: The research findings (Total Four Mediating Roles) suggest that psychological empowerment may mediate between leadership and employee motivation. These mediation roles (Empowering Leadership Styles, Organizational Culture and Psychological Empowerment, Customer Psychological Empowerment, and High-Performance Work Systems (HPWS) and Psychological Empowerment) will help practitioners comprehend how these empowerment and motivation leadership styles are interconnected in the retail industry. Conclusions: The research results indicate that psychological empowerment is essential for employee motivation in the retail sector. Through this knowledge, retail store managers can implement strategies designed to empower employees and create a motivated workforce, bolstering organizational effectiveness.
