This study investigates the stability and performance of high-resistance badminton nets through the integration of reinforced lightweight materials. By focusing on the structural and economic impacts, the research aims to enhance both the durability and practicality of badminton nets in professional and recreational settings. Using a combination of advanced material engineering techniques and economic analysis, we explore the development of nets constructed from innovative composites. These composites offer improved resistance to environmental factors, such as weather conditions, while maintaining lightweight properties for ease of installation and use. The study employs high-order shear deformation theory and high-order nonlocal theory to assess the mechanical behavior and stability of the nets. Partial differential equations derived from energy-based methodologies are solved using the Generalized Differential Quadrature Method (GDQM), providing detailed insights into the thermal buckling characteristics and overall performance. The findings demonstrate significant improvements in net stability and longevity, highlighting the potential for broader applications in both the sports equipment industry and related economic sectors. By bridging the gap between material science and practical implementation, this research contributes to the advancement of high-performance sports equipment and supports the growth of the sport economy.

Purpose: The purpose of this study is to provide fundamental information for professional sports and economy activation of cities, to explore mutual cooperative constructive relationship, and to investigate the Impact of Korean professional volleyball teams brand personality on city brand equity. Research design, data, and methodology: The study collected 500 survey responses and analyzed 478 surveys except for 22 which did not complete all items. For analyzing data, frequency, reliability, exploratory factor analysis, t-test, One-Way ANOVA, correlation, Multiple Regression were computed. Results: First, in difference in brand personality and city brand equity, due to gender, age, region of fan, significant difference were shown statistically in team image by gender, in honesty, interest and obdurability of brand personality by age, and in local community contribution, development possibility and sports facility of team image. Also, all factors show significant difference in region of fan. Second, regarding the impact of brand personality on city brand equity, honesty and capacity were shown to affect every factor of city brand equity, interest affected city image, and obdurability affected city perception. Conclusion: Professional teams need to develop win-win relationship with local community and seek to build positve image towards community fans via distinctive strategies for positioning.

The purpose of this study is to analyze the economic efficiency of the policy implemented by Ministry of Culture, Sports and Tourism on leading company in sport industry. The leading companies in sport industry are those who have a certain amount of sales in sport industry and the ones with potential to become global companies. Supporting areas include business advancement, overseas market development, and overseas PR marketing integration support. The research is performed by developing the equilibrium model composed of supply as well as demand and applying input-output analysis. The economic efficiency is estimated to in the form of changes in the sales of corporations and the ripple effect of the national economy. The results of the study are as follows. First, it is estimated that the sales growth rate of the company due to the implementation of the policy is from 3.74% to 5.19%. Second, the increase in sales reaches to a maximum of KRW 4,081 billion with a minimum of KRW 1,573 million, depending on the size of the company. Third, it is estimated that the production inducement effect for the national economy is from KRW 36 billion to KRW 93.4 billion. Fourth, the induced value added for the national economy is estimated to be at least KRW 11.3 billion, up to KRW 29.2 billion.

Purpose - As society continues to develop and the economy grows, consumer participation in sports activities and consumption of sports-related goods are steadily increasing. Nowadays, Spyder, the sporting goods company has achieved great success in the Korean market. In the launching, Spyder tried to communicate the sport authentic brand value to consumers as successful sporting goods brands did. The purpose of this study is to identify the key factors influencing the successful branding strategies of sporting goods retailers. In the process of value trading to the consumer, the concept of authenticity which includes 'originality', 'truth' and 'genuine' is considered as one of the most important factor for branding. This study tries to define the brand authenticity in sporting goods retailer and to develop measurement scale. This study suggests a new paradigm for sports brand research and implications for management of domestic sporting goods retailer that is losing the direction to develop brand value. Research design, data, and methodology - This research consists of two parts of study. The first study is a qualitative research to define sport brand authenticity and measuring items through expert interviews. The second study is the development of scales to the authenticity. And reliability and validity of the scales are verified by quantitative methods. A total of 500 respondents were surveyed and the statistical tests were conducted by dividing two groups. Results - This study defines the authenticity of sports brand which is divided into four dimensions; behavioral authenticity, performance authenticity, spiritual authenticity and virtuous authenticity. And this newly defined four dimensions measurement tool is proved statistically in this study in terms of reliability and validity. Conclusions - For the success of sporting goods retailers, it is important to understand the value of sport and to communicate it with customers effectively. This study suggests a tool for sport brand authenticity and also significant implications for brand strategies. In addition, every entity which is related with sport can apply the measurement scale of this study to understand their position and find direction in terms of authentic sport value.

Recently, intensive research efforts are world-widely forced on the development of sport shoes improving both the injury protection and the playing performance by taking kinesiology and biomechanics into consideration. However, the success of this goal depends definitely on the reliable evaluation of the dynamic responses of sport shoes and human foot, particularly the landing impact characteristics. It is because the landing impact force is a main source of unexpected injuries and influences the playing performance in court sport activities. This paper addresses the application of finite element method to the evaluation of landing impact characteristics of barefoot and several representative court sport shoes in running. In order to accurately reflect the coupling effect between human foot and shoes accurately, we construct a fully coupled three-diemensional foot-shoe FEM model which does not rely on the independent experimental data any more. Through the numerical simulation, we assessed the reliability of the numerical FEM model by comparing with the experimental results and investigated the landing impact characteristics, such as GRF, MIF, acceleration and frequency responses, of representative court sport shoes.

This study is conducted to propose an activation plan for fisherinas by analyzing in depth the needs for fisherina development. For this purpose, the result is derived through the analysis of literature, in-depth interviews and Delphi methods. As a result, the need for fisherina development is shown as follows: first, the saturation due to the increase of maritime recreational vessels; second, the possibility of economic development; third, the activation of the fishing village economy. Accordingly, the problems of the fisherina are derived, first, the conflicts with fishermen and recreational vessel users, second, the financial difficulties, third, the lack of infrastructure. The activation plans for fisherinas are as follows: first, forming a consultative body centered on stakeholders; second, ensuring financial soundness; third, building infrastructure by linking businesses; and fourth, systematic supplementary plans. These results will play an important role in expanding the underdeveloped domestic fisherina business and will be another step in activating the maritime leisure industry.
