In this paper, we will study the application of coupled annular nanoplates on basketball equipment to enhance energy absorption and vibration control by incorporating a viscoelastic substrate between the two nanoplates and get their dynamic behavior and possible way for performance enhancement of advanced sports material. Higher-order shear deformation theory is used to formulate the mathematical model, while the finite element method (FEM) is employed to estimate vibrational frequencies and energy absorption. Our results highlight how the critical parameters would affect the vibration and energy absorption characteristics of coupled annular nanoplates on basketball equipment. In fact, the findings in this paper have demonstrated the possibilities for nanostructured materials to enhance durability, energy efficiency, and vibration isolation in basketball sports equipment. The use of such advanced materials in conjunction with the theoretical framework given in the work will allow development pathways toward high-performance sporting goods that are optimized for dissipative and impact-resistant energy. This will provide innovations in sports engineering.

Sport has no age limit and can be done anywhere and in any condition with minimal equipment. The existence of sports spaces in all parts of the world is considered a citizen's right. One of the activities carried out in this field is installing sports equipment and structures in parks and encouraging citizens to use this equipment for physical health with the least cost and facilities. Installing sports structures in open spaces such as parks is a practical step for developing citizens' sports. Although using devices in parks is acceptable, it is more critical to meet scientific and technical standards. The components of these structures must have high strength and endurance against changes in environmental conditions such as humidity, temperature difference, and corrosion. Among the various causes of material degradation, corrosion has always been one of several fundamental causes of metal equipment failure. Sports structures in open spaces are not safe from corrosion. Uniform corrosion is the most common type of corrosion. This corrosion usually occurs uniformly through a chemical or electrochemical reaction across the surface exposed to the corrosive environment. Rust and corrosion of outdoor sports structures are examples of this corrosion. For this reason, in this research, with the green synthesis of silica nanoparticles and its application in outdoor sports structures, the life span of these structures can be increased for the use of physical exercises as well as their quality.

우리나라는 선진대열 진입 무렵부터 '스포츠'의 긍정적 효과에 대한 유용성을 경험해 왔다. 이를테면 올림픽 등 국제대회 개최는 국가 내외적 발전을 추동하였다. 국가홍보에 기여한 바도 매우 크다. 우리나라의 인지도를 향상시킨 매개체로서 스포츠 이상의 경쟁력 있는 콘텐츠는 드물다. 실제로 스포츠는 국가발전을 리드하는 중요한 역할을 수행해왔다. 그 결과 우리나라에서는 스포츠에 대한 투자확대와 수요증대라는 선순환 구조가 체계화될 수 있었다. 그간 스포츠의 육성과 진흥에 대한 노력은 산업적 부가가치의 창출로 이어지는 경향을 갖추게 되었다고 할 수 있다. 이러한 스포츠 생산성에는 다른 분야들과 구별되는 장점이 있다. 비교적 균형 있게 성과를 국가 전반으로 환원시킨다는 점이다. 이상의 관점에서 본고는 우리나라 스포츠 시설의 안전성 증진을 위한 법제도적 측면의 발전방안을 제언하고자 하였다. 국가는 스포츠 시설을 체계적이고 적극적으로 관리할 책임과 의무가 있다. 여기에는 국가 및 공공의 스포츠 시설만이 아니라 민간 스포츠 시설도 포함된다고 할 수 있다. 스포츠 발전과 국가 발전의 공진화적인 관계는 앞으로 더욱 넓게 확대될 것이므로 그에 대한 철저한 준비가 필요하다.

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.

This paper aims to research the technology level of sports industry, through analyzing the technology gap between Korea and other major countries (USA, Europe, Japan, and China), and provide a list of technologies to be prioritized for R&D investment by conducting an analysis of the strategic importance of various element technologies. The results of the analysis showed that the technology level of Korean sports industry currently stands at 70.5% of the country with the most advanced technology (the USA), and that the technology gap amounts to 4.8 years. It was also found that the USA is the country with the most advanced technology (100%) at present, followed by Europe (91.1%), Japan (88.3%), Korea (70.5%), and China (61.2%). To reduce the technology gap, we established a Strategic Zone (SZ) and derived three element technologies including 'design and production technologies for sports and game equipment' in the $1^{st}$ tier, nine element technologies including '3D motion analysis and simulation technology' in the $2^{nd}$ tier, and four element technologies including 'fitness/health promotion and management technology' in the $3^{rd}$ tier. The significance of this research is that it included five major technology categories of the sports industry in its analysis, selected an expert on sports industry technologies using the delphi method. Therefore, the results of this study may be suitable for use as basic data in establishing the R&D strategy for the future development of the sports industry.

As the number of kids cafes, one of the children's playgrounds, is increasing rapidly, safety accidents in the kids cafe are also increasing rapidly. The facility is also increasing as the need increases, but it is spreading without ensuring safety. In particular, the Ministry of Public Administration and Security for children's play facilities in the kids cafe, and the Ministry of Culture, Sports and Tourism for organic organizations are divided into different departments, so it is not easy for local governments to manage and supervise the actual business, and there are safety blind spots. Kids cafes have changed rapidly according to needs of children and guardians who are users, and there are many problems associated with them. Therefore, we identified problems that may arise due to insufficient safety management systems for kids cafes, investigated the safety management related to kids cafes in advanced countries, and compared and analysed them with domestic systems. As a result of the research, we proposed a safety management reinforcement system, and we hope to contribute to the reduction and prevention of kids café safety accidents.
