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 studies the long-run behavior of relative price dispersion among cities in Korea with a special emphasis on heterogeneous transitional patterns of price level dynamics. Formal statistical tests indicate considerable evidence for rejecting the null of relative price level convergence among the majority of cities over the sample period of 1985-2015. The analysis of gravity model suggests that the effect of transportation costs on intercity price level differentials is limited, while other socioeconomic factors, such as income, input factor prices, demographic structure, and housing price growth, play key roles in accounting for persistent regional price level disparities. Individual price levels are found to be better explained by a multiple-component model, and the deviations from PPP may be attributed to distinct stochastic common trends that are characterized by income and demographic structure.

This paper was designated to review consumer complaining in the context of consumerism . For the purpose of this study, the literature in the consumer satisfaction/ dissatisfaction, complaining and noncomplaining behavior was reviewed. A conceptual approach to understanding why consumers complain or not when the dissatisfied was presented. It was suggested that regardless of how dissatisfied a consumer is , an action is taken or forgone only after the costs and benefits of the various alternative are considered and an assessment of the probabilities of success are made. It was suggested that aroused citizens through consumer education, government agency's effort to reduce the consumer's dissatisfaction and seller's marketing strategy in the view of consumerism are three main propositions for the enhancement of the consumer's quality of life in this study. Consumer complaining must be made in virtue of national economic systems( standard of living and the effectiveness of its marketing system, extent of government control and provision of consumer assistances) to achieve high levels of efficiency. Besides national economic systems. the third parties must be promoted for the efficient consumer complaining.

Household debt in Korea raises concerns about the resilience of the economy due to its size and quality. Against this backdrop, we investigate if household leverage matters for private consumption in adverse economic environments even without severe financial disruptions. We find that the balance sheet positions in terms of the leverage ratio may weaken consumption growth. We also find that the depressive effect of debt on consumption may differ across types of consumer spending and household characteristics. In particular, the effects of indebtedness have been much stronger in relation to durable goods expenditures than in other areas. In addition, debtors in high-income (wealth) groups have also shown downward adjustments in consumption even more so than low-income (wealth) groups. These findings imply that debtors' precautionary behavior may serve as an important channel from leverage to consumer spending.

Purpose: In an attempt to investigate causes of runaway impulse in male and female students with runaway impulse experience in high schools, this study was carried out. Methods: The subjects were 195 high school students in Gyeonggi and Incheon area. The data were collected by using the questionnaires. Results: To both male and female students, the main causes of runaway impulse were 'conflicts with parents', 'interference and excessive expectations of parents' and 'burden of study and grades'. In cases of youth with runaway experience by runaway impulse, the major causes of runaway impulse were 'want to have fun with friends' and 'conflicts with parents'. Also shelter and economic difficulties were obstacles that prevent a runaway despite runaway impulse to both male and female students. But in female, the fear and anxiety about runaway were higher barriers than those of male. Conclusion: From the above results, major causes of runaway impulses were relationships with parents, and burden of study. And barriers to prevent a runaway were shelter, economic difficulties to both male and female students.

This paper examined the impact of psychological characteristics of consumers on household debt decisions. With the use of the Heckit models (the traditional approach to the selection problem) this study undertook an empirical study of the influence of a wide range of factors on financial decisions. This study used U.S. household-level data that offers detailed information on household debt, expectations about future income, expectations about future economic conditions, the amount of financial risk the respondent was willing to take, and the amount of time allotted for planning family savings and spending. This study showed that respondents with both substantial financial risk tolerance and positive expectations about future income were likely to have larger household debt showing that researchers and policy-makers need to consider consumer sentiment and preference measures in modeling behavior in credit markets. Additional results showed that household debt is significantly related to two key economic variables: income and net worth.

This study investigates the effects of economic factors on happiness in terms of life satisfaction, one of the most important goals in human life, and examines the moderating role of financial management in the effect of financial stress. Data were collected total 341 individuals in Daejeon, Korea(235 college students and 105 women). The factors influencing life satisfaction were analyzed multiple regression analysis. Effects of moderating variables were tested hierarchical regression analysis. Subjective financial stress was related to both individualistic happiness and collectivistic happiness, whereas objective financial stress had a negative effect only on collectivistic happiness. Financial management (specifically control of expenditure behaviors) had positive effects on both individualistic happiness and collectivistic happiness. Financial management moderated the relationship between financial stress and happiness. The results have important implications.

Prader-Willi syndrome (PWS), a complex genetic disorder, arises from suppressed expression of paternally inherited imprinted genes on chromosome 15q11-q13. Characteristics include short stature, intellectual disability, behavioral problems, hypogonadism, obesity, and reduced bone and muscle. The life expectancy of persons with PWS has increased in recent years. Cardiovascular diseases, diabetes, dermatological, and orthopedic problems are common physical complaints in older people with PWS. Behavioral problems are major concerns in adults with PWS into old age. And aging is also associated with significant social and economic changes. Age-related physical morbidity, physical appearance, behavioral and psychiatric problems, functional decline and economic problems can be combined in older PWS. The care for older people with PWS requires a life span approach that recognizes the presence, progression, and consequences of specific morbidity.
