Sport industry creates value-added by production and distribution of product or service related with sports or sports. Because this industry shows promise in becoming a major industry area, the government is making an effort to bring up or develop it. The financing to firms of sport industry area(sporting goods industry, sport facility industry, sport service industry) with low interest rate and long-term repayment period on the basis of sports promotion fund is excellent scheme to promote sport industry. Nevertheless, Because many people indicate operational inefficiency of it, it is necessary to check operational efficiency through investigation for loan system of sports promotion fund. The purposes of this paper are to analyze public loan system using funds of other government organization and to the current status of loan system of sports promotion fund.

Purpose: This study sought to examine the symbolization of brand identity in Nike golf advertisements and to provide implications for sporting goods ads. Research design, data, and methodology: The study employed Socher's semiotic theory to analyze characteristics embedded in Nike video advertisements. In specific, the study selected 'No cup is safe' among Nike video ads and analyzed structures of ad message and presented metaphors of ad messages. Results: As a study on the semiotic analysis of communication by case, this study investigated how the brand identity pursued by Nike in the advertisement is symbolized by identifying the signifier and signified in the advertisement. As a result of the study, it was possible to segment and analyze a total of 8 advertisement scenes, from the most important tee shot in golf, setting the aiming, sending to the center of the fairway, and applying the general situation of ball in and hole out to the cases of Tiger Woods and McIlroy, thereby helping the general public. Conclusions: Summary of above results showed that it was also conveying the message of metaphor and metonymy that 'I can be like Tiger Woods and McIlroy' by using Nike golf products. Further implications were discussed.

Composite materials, being light-weight and of high mechanical strength, are increasingly used in various industries such as the aerospace, automobile, sporting-goods manufacturing, and ship-building industries. Recently, manufacturing of composite materials using 3D printers has increased. 3D-printed composite materials are made in free-form and adapted for end-use by adjusting the fiber content and orientation. However, research on the machining of 3D printed composite materials is limited. The aim of this study is to develop a machine learning method to select machining conditions for machining of 3D-printed composite materials. The composite material was composed of Onyx and carbon fibers and stacked sequentially. The experiments were performed using the following machining conditions: spindle speed, feed rate, depth of cut, and machining direction. Cutting forces of the different machining conditions were measured by milling the composite materials. PCA, a method of machine learning, was developed to select the machining conditions and will be used in subsequent experiments under various machining conditions.

Composite laminates are used in a wide range of applications including defense, automotive, aviation and aerospace, marine, wind energy, and recreational sporting goods. These composite beams still exhibit problems such as buckling, local deformations, and interlaminar delamination. To overcome these drawbacks, a novel viscoelastic autoclave bonding with tapered epoxy reinforcement polyurethane films is proposed. In existing laminates, compression face wrinkling and interlaminar delamination is caused in the sandwich beam. The unique viscoelastic autoclave spunbond interlayer bonding is designed to prevent face wrinkling and absorb and distribute stresses induced by external loads, thereby eliminating interlaminar delamination in the sandwich beam. Also, the existing special reinforcement causes stress concentrations, and the core is not effectively connected, which directly affects the stiffness of the beam. To address this, a novel tapered epoxy polyurethane reinforcement adhesive film is proposed, whose reinforcement thickness gradually tapers as it enters the core material. This minimizes stress concentrations at the interface, preventing excessive adhesive squeeze-out during the bonding process, and improves the stiffness of the beam. Results indicate the proposed model avoids the formation of micro cracks, interlaminar delamination, buckling, and local deformations, and effectively improves the stiffness of the beam.

Due to recent industrial growth and development, there has been a high demand for light and highly durable materials. Therefore, a variety of new materials has been developed. These new materials include carbon fiber reinforced plastic (CFRP or CRP), which is a wear-, fatigue-, heat-, and corrosion-resistant material. Because of its advantageous properties, CFRP is widely used in diverse fields including sporting goods, electronic parts, and medical supplies, as well as aerospace, automobile, and ship materials. However, this new material has several problems, such as delamination around the inlet and outlet holes at drilling, fiber separation, and tearing on the drilled surface. Moreover, drill chips having a fine particulate shape are harmful to the work environment and engineers' health. In fact, they deeply penetrate into machine tools, causing the reduction of lifespan and performance degradation. In this study, CFRP woven and unidirectional prepregs were formed at $45^{\circ}$ and $90^{\circ}$, respectively, in terms of orientation angle. Using a high-speed steel drill and a TiAIN-coated drill, the two materials were tested in three categories: cutting force with respect to RPM and feed speed; shape changes around the input and outlet holes; and the shape of drill chips.

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist industrial applications. The high cost of CF is a problem in various applications and the use of CFRP has been impeded by the high cost of CF in various applications. This paper presents an overview of research related to the fabrication of low cost CF using polyethylene (PE) control technology, and identifies areas requiring additional research and development. It critically reviews the results of cross-linked PE control technology studies, and the development of promising control technologies, including acid, peroxide, radiation and silane cross-linking methods.

A bicycle is one of the most popular sporting goods in view of a sport activity and a human health. Metallic materials such as steel, aluminum, etc. were mainly used to the bicycle fork in the past. Nowadays, the carbon fiber reinforced composite materials are widely used to the manufacturing of a bicycle fork to reduce the weight and to increase the efficiency. Safety is a most important design parameter of a bicycle fork even if the weight and cost reduction are important. Bicycle failure may happen at the critical spot of a bicycle fork and cause the accident. In this paper, the composite bicycle fork will be analyzed to secure the safety and detect a critical spot by using the finite element method with Tsai-Wu failure criterion. The stress data were obtained for the laminated composites with various number of plies and fiber orientation under the bending load. Thus, design concept of a bicycle fork was proposed to secure the safety of a bicycle. The finite element analysis results show that the connection area between a steer tube and a fork blade is critical spot, and 75 or more layers of 0 degree are needed to secure the safety of a bicycle fork.

Purpose - The study aims to analyze the VMD(Visual Merchandising) perception factors in recent sporting goods store and clarify the effect of each VMD perception factors on brand image, satisfaction, and customer revisit intention. The VMD perception factors play an important role in attracting and actually inducing sales to the visiting customers. It has investigated the effect of VMD perception on customer satisfaction and revisit intention. It is expected that the company's marketing strategy with VMD will be differentiated and competitive in sports item stores, brand image enhancement, customer retention, and acquisition. Research design, data, and methodology - In order to verify the hypotheses of this study, a total of 380 questionnaires had been distributed. 360 respondents were used in the final analysis excluding 20 respondents' incomplete answers. The SPSS 18.0 program was used and the data analysis was conducted for the demographic characteristics and distribution behavior. Principal Components Analysis was used for the common factor extraction for validity analysis, and factor analysis was conducted to verify such as validity in brand image or brand attitude. As for Multiple regression analysis, was performed to verify and in the research model, and in and , the mediation was defined through the Sobel Test in order to verify the brand image mediating effects on VMD, store satisfaction, and revisit inquiry of sports store. Results - Qualitative research shows that VMD sub-variables such as aesthetic, fitness, and functional convenience influence store satisfaction and revisit intention. As a result of analyzing the mediating effect of the brand image, the more VMD is strengthened, the more brand image is improved and store satisfaction is also increased. Conclusions - VMD enhancement requires a VMD strategy aligned with the company's management policies and objectives, a visual directing and consistent concept that delivers a strong message to customers. The customer actual purchasing behavior is a combination of various factors such as sports item stores' interior design, display, advertisement promotion like POP(Point of Purchase), salespersons and their service quality, so that the VMD image and the brand image must be consistent and a unique strategic plan is required.

The concept of Corporate Social Responsibility (CSR) was first introduced sixty years ago in the academic field. However, the phrase CSR was not explicitly stated before the 1990s in Korean business and academic researches. Recently CSR is more considered a corporate strategy than a philanthropic donation. CSR comprises contributions to local communities as well as using environmentally beneficial and humane practices. Sponsoring is one available marketing tactic used in order to communicate with the market. This study of sponsorship has concentrated on developing brand asset by accessing potential values of sporting events or star-players. However, sponsorship includes providing funds or goods to non-profit institutions as well as sports or entertainment organizations. Accordingly corporate community-specific sponsorship is defined as firms offering to provide money, goods and/or services to individuals and/or institutions within a particular community, thus establishing an interdependent relationship between the partners aspiring to gain social and economic assets. National sponsorship is typically targeted toward commonly recognized individuals and/or organizations with the intent to maximize exposure of a sponsor's brand, and is known to positively affect brand equity(community-specific sponsorship is committed to a limited local area) that a firm could benefit from by gaining a specific asset. POSCO sponsors the Jukdo Market, locate dinthe city of Pohang, tohelp revive their traditional market. Inreturn, the Jukdo Market merchant suni on display sflags with the POSCO embleminfrontof stores with in the market intending to make shopper sand merchant saware of POSCO's sponsorship. POSCO has succeeded in acquiring public support from the citizens of Pohang. However, the economic effects resulting from the cooperative relationship between POSCO and the Jukdo Market have yet to be measured by any empirical research. The purpose of this study is to assess the economic effects created by the community-specific sponsorship from the groups of merchants and shoppers, measuring its influence on the corporate image and subsequent brand loyalty, as parts of brand equity. The result of the study shows that the community-specific sponsorship of POSCO of the Jukdo Market had different influences on its corporate image and the brand loyalty of shoppers and merchants. First, the merchant group who was more frequently exposed to POSCO's flag recognized the sponsorship of POSCO more than the shopper group, and, therefore, had a better image of the company. Second, the recognition of POSCO's sponsorship had a positive influence on its corporate image, and that positive corporate image had a positive effect on brand loyalty development. However, the recognition of the sponsorship did not have a direct influence on brand loyalty. The friendly corporate image developed by the recognition of the sponsorship consequently could have had an effect on brand loyalty. Therefore, companies should not relinquish investments to corporate image development if they require more brand loyalty. Third, the influence of corporate image on brand loyalty shows stronger results in the shopper group rather than in the merchant group. Psycho-graphic factors of shoppers and merchants might give rise to the difference between the two groups.

This study sets out to examine how a brand image that matches the advertising model has a positive impact on brand attitude and price fairness perceptions. We reviewed the constructs on the basis of previous studies and each of the concepts has been redefined. One such concept, "image congruence," refers to the harmony, fitness, and matching quality of images. For example, how well celebrity advertising model is matches the brand image shows image congruence. Results are summarized as follows: First, the congruence of brand image and sports advertising model has no significant impact on brand attitude certainty and persistence. Second, the individual's brand attitude certainty and brand attitude persistence has a positive impact on the perceptions of price fairness. Third, the congruence of brand image and sports advertising model has a positive impact on the perceptions of price fairness. The first and the third results suggest that the positive impact on the price fairness perceptions is temporary but it has insignificant effects on the formation of brand attitude causing ongoing purchases. In other words, in order to influence consumers' long-term confidence on the brand, improving the quality of products or services has to precede promotional strategies such as advertising. When an advertising model is inappropriate for the brand image, consumers perceive product price changes as a negative issue in the short term. However, in the long term, attitude formation such as consumers' repurchase intentions and word of mouth will be not affected. The second result suggests that an already existing positive brand attitude can contribute more positively to change the perceptions of price fairness. In particular, attitude persistence has greater influence than attitude certainty on the price fairness. It suggests that persistence issues such as the trading period and the frequency of transactions must be managed and controlled because they are more important than the certainty issues such as strength of belief or trust. For example, when a commercial model for expensive sporting goods matches up with the brand image, consumer feels less pressure on the price changes. However, it does not determine the consumer's repeated purchases or sustainable transactions and it also has no absolute impact on the brand trust. In other words, consumer brand attitude should be recognized and approached as a routine strategy in view of the result that it is of great value as a causal variable in the process of consumer decision-making.
