This study aimed to identify the effects of sports participation motives, the involvement in choosing sportswear, and the satisfaction with/perceived importance of sportswear functionality, on customers' repurchase intentions. A total of 185 survey questionnaires were analyzed after surveying 200 female undergraduates in their 20s. The research results are as follows. First, the participation motives for sports were categorized as follows. A factor analysis conducted on 13 questions yielded 4 factors. Factor 1 included consideration about socializing and pleasure, factor 2 privileged ostentation, factor 3 was concerned with enhancing health, and factor 4 was about maintaining appearance. Second, the various effects of different sports participation motives, of the satisfaction with functionality, and of the involvement in buying sportswear on customers' repurchase intentions were analyzed. The intention to repurchase sportswear was considered as a dependent variable, while the motives for participating in sports, the satisfaction with functionality, and the level of involvement were treated as independent variables. A multiple regression analysis using these variables showed that the satisfaction with functionality and involvement in choosing sportswear had a significant impact on the intention to repurchase sportswear. Third, looking at how different participation motives for sports affected the importance of sportswear functionality, the motives related to socializing and pleasure and ostentation, the sub-factors in sports participation motives, significantly increased the importance of comfort. Motives related to enhancing health and maintaining appearance, on the other hand, were found to affect the importance of sports performance. Fourth, a MANOVA was performed to examine the difference in the importance of functionality between those consumers highly involved in sportswear-buying and those less involved. Those with a high level of involvement were found to prioritize sports performance over comfort. Those with a low level of involvement were shown to place a greater emphasis on comfort.

The purpose of this study was to investigate the buying behavior of sports apparel brand in relation to the involvement of specific professional football teams. A total of 256 adults in their 20s and 30s who residing in Seoul, Suwon, Inchon, and Daejeon completed questionnaires. Data were analyzed by using SPSS 11.0. Major statistical methods were frequency analysis, t-test and Chi square analysis. The results of this study were as follows; 1. The high involvement group of the specific professional football team showed a higher degree in the recognition, the preference, and the buying intention on sports apparel brands than the low involvement group did. Results showed statistically significant differences in responses to preferred items and store types between the low- and high involvement group. 2. With regard to the preference of sponsored apparel brands and the number of own items according to the preference of specific professional football teams, the group who preferred FC Seoul and Suwon Samsung Bluewings had a higher preference and own more items than the less preferred group did. 3. Male respondents were found to have a higher degree in the recognition, the preference and the buying intention than female respondents were. Also, there were differences in responses to a preferred store type between males and females.

The purpose of this study was to investigate and verify interaction effects of collaboration and brand origin as well as fashion involvement on consumer attitudes towards global sports apparel brands and Chinese local sports apparel brands targeting Chinese consumers. A survey was conducted on 425 Chinese women aged 19 to 34 years. Data were subjected to frequency analysis, reliability analysis, t-tests, 3-way ANOVA, and simple effect analysis. Results of the study are as follows. First, fashion involvement, collaboration, and brand country of origin all had a significant effect on consumer preference of Chinese consumers when purchasing sportswear. Second, fashion involvement and collaboration in purchasing sportswear had a significant interaction effect on consumer preference. Finally, collaboration, brand origin, and fashion involvement showed significant three-way interaction effects on Chinese consumers' preferences. Results of this study can help establish an efficient marketing strategy for Chinese local sportswear brands, which are fiercely competing with global sportswear brands in the Chinese market because they can examine Chinese consumers' attitudes toward sportswear brands. To accurately compare global and local sportswear brands, it must be assumed that there are no differences in brand preferences among consumers. However, as this study selected each brand as the research brand ranked as the top preference, this aspect was not taken into consideration. Therefore, in future research, it is necessary to consider differences in brand preferences and conduct the study accordingly.

The purposes of the present study were to investigate the impact of a apparel brand and an ingredient brand on evaluation(perceived quality, favorable attitude, purchase intention) of apparel products, and to examine the differences in evaluations toward apparel products allied with ingredient brands between groups divided by product knowledge and leisure involvement. The subjects were 235 men and women aged 20 to 40. Two-by-two factorial design were employed. A series of ANOVA were used to determine if significant differences existed in evaluations of apparel products. There was a significant interaction effect of an apparel brand and an ingredient brand on evaluations of apparel products. Empirical results showed that ingredient brands would improve the consumers' perceived quality, favorable attitude and purchase intention toward apparel products. In addition, the results indicated that the respondents that had high leisure involvement and high product knowledge were more likely to evaluate apparel products based on the ingredient brand of the products. However, the respondents that had low leisure involvement and product knowledge were more likely to evaluate apparel products based on the host brand of the products.

Purpose: The purpose of this study was to determine how many of our patients who had had anterior cruciate ligament (ACL) reconstruction returned to their previous levels of sports and to identify why not doing so. Material and Methods: We evaluated 43 knees with a minimum of two years follow-up among whom undergoing 109 ACL reconstruction from September 2003. The mean age of patients was 26 years (17 to 45 years) Clinical results was evaluated according to the Lysholm Knee scores, Tegner activity score, subjective IKDC questionnaires, objective IKDC evaluation form and KT-1000 arthrometer. Results: The overall clinical results demonstrated significant improvement at the final follow-up comparing to preoperative data (P<0.05). Among 43 patients, 25 patients (58%) returned to their previous level of sports and 18 patients (42%) did not. Of whom, 11 patients (61%) were not able to return to sports due to fear to re-injury and 7 patients (39%) suffered from instability and pain. The differences in the Lysholm Scores, KT-1000 arthrometer and subjective IKDC in the 3 groups of patients by ANOVA test were found to be statistically significant (P<0.001). Although there is no difference in objective IKDC and KT-1000 arthrometer, the difference was observed in Tegner activities, subjective IKDC obtained by those who returned to sport and those who had fear to reinjury (P<0.001). Conclusion: This study showed that a quater of patients could not return to their previous level of sport after ACL reconstruction because of fear to reinjury. We thought that not only improving the technique of ACL reconstruction and systemic rehabilitation but also considering psychological factor of patients could allow more patients to return to the previous level of sports.

Purpose: The anterior cruciate ligament(ACL) has a neuromuscular control function as evidenced by the presence within it of mechanoreceptor. Although these mechanoreceptors have been identified, the afferent somatosensory pathways from ACL to the cerebrum have yet to be demonstrated in their entirety. In order to trace these afferent pathway, we conducted a viral trans-synaptic tracing experiment using the neurotropic pseudorabies virus(PRV). Material and Methods: The PRV was injected into the ACL of rats and allowed to replicate and spread trans-synaptically for 6 to 7 days. The brain and spinal cord of each sacrificed rat was then removed and processed immunohistochemically to detect the presence of PRV. Results: PRV-immunoreactive neurons were found to be localized in several different regions from the spinal cord to the cerebrum. Four nuclei in the reticular formation of the brain stem demonstrated strong positive labeling: the mesencephalic reticular nucleus, magnocelluar reticular nucleus, paragigantocellular reticular nucleus, and gigantocellular reticular nucleus. Conclusions: This findings suggests that the nerve endings of the rat ACL project into the cerebrum and that the reticular formation may play an important role in the afferent pathway of those nerve endings.

The objective of this study examines that a country-of-origin and a congruity between country-of-origin of brand and country-of-origin of production effect on consumers' product preference respectively. To test this hypothesis, we used stimulus material including product photos with brand and its production description. Nation selected for study is defined as developed country, Korea, underdeveloped country, and tape record, sports shoes, and cosmetic, tissue is selected, they have characteristics with thinking vs feeling, level of involvement, private vs public. The result of analysis show that the effects of country-of-origin on product preference is different over country. The product of developed country is preferred by subjective, and following Korea, underdeveloped country. This result imply that country-of-origin effect on consumers' product preference and product evaluation positively. And we found that the degree of congruity between country-of-origin of brand and country-of-origin of production has very substantial impact on product quality judgement and product preference above and beyond brand and country-of-origin of production main effects. This study contributes to a understanding of effects of country-of-origin at the perspective of congruity, and extend level of generalization of country-of-origin effect by testing various product characteristic and congruity.

The purpose of this study was to propose a product planning and design direction for smart fitness wear that will improve the impact of personal training based on researching the requirements of smart fitness wear and its acceptance level, as well as the functional demand. The study conducted in-depth interviews with professional fitness trainers and derived five categories and thirteen keywords by analyzing the categorical data analysis using the interview data. In addition, we surveyed general consumers to measure the acceptance level of smart fitness wear and the functional demand for product development. The results revealed that the difference in the acceptance level of smart fitness wear generally depended on the characteristics related to exercise involvement and exercise-related culture rather than on the demographic characteristics. With regard to the difference in the functional demand of smart fitness wear, the results showed that professional trainers focused on the scientific improvement of the effect of exercise while general consumers focused on the function that considers the sustainability of exercise. Based on the results, we proposed product planning and design directions such as 'mounting of heart rate sensing, muscle activity sensing, motion angle or posture sensing, and motion sensing', 'development of concepts and contents for expert line, ordinary line', 'compression wear design', and 'differentiation of product development according to exercise areas'.

UV irradiation causes a variety of biologic effects on the skin. These effects can be devided to acute reactuons and chronic reacxtions by duration of UV irradiation. Acute reactions are erythema reaction, pigment reactions and changes in epidermal thickness. Among them erythema reaction is most common and conspicuous acute effects of the skin. Upon exposure to sun or artificial UV soures, a faint redness response of skin may begin. Larger exposure causes sunburn reaction which is exaggerated erythema reactionassociated with pain, swelling, vesicle and dulla. Extent and time course of erythema reaction depend upon several factors including wavelength and dose of UVR, skin conditions likeas skin type, site, color, temperature, humidity and environmental factors. Evaluation of erythema erythema induced by UV irradiation is difficult to quantify. Degree of redness of skin are usually estimated by subjective visual evaluation. The lowest exposure dose required to protuce erythema is called minimal erythema dose (mod). Repeated exposures of UVR result in photaging skin. In this condition we can see wrinkling, skin atrophy, dilated blood vessels and keratoses. In sensitive persons photocarcinogenesis is can Be developed on exposed area of skin. Recently skin canser is increasing now in our country. An effective public education and photopreventive method must be developed.

Exercise increases the expression and interaction of major neurotrophic factors such as brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF) at both central and peripheral tissues, which contributes to improved brain and neural plasticity and cognitive function. Previous findings have been to understand the effect of light or moderate intensity aerobic exercise on neurotrophic factors and cognitive function, not that of high intensity aerobic exercise. However, recent findings suggest that high intensity interval training is a safe, less time-consuming, efficient way to improve cardiorespiratory fitness and weight control, thus American College of Sport Medicine (ACSM)’s guidelines for exercise prescription for various adult populations also recommend the application of high intensity interval training to promote their overall health. High intensity interval training also enhances the expression of BDNF, IGF-1, and VEGF at the brain and peripheral tissues, which improves cognitive function. Increased frequency of intermittent hypoxia and increased usage of lactate as a supplementary metabolic resource at the brain and neural components are considered a putative physiological mechanism by which high intensity interval training improves neurotrophic factors and cognitive function. Therefore, future studies are required to understand how increased hypoxia and lactate usage leads to the improvement of neurotrophic factors and what the related biological mechanisms are. In addition, by comparing with the iso-caloric moderate continuous exercise, the superiority of high intensity interval training on the expression of neurotrophic factors and cognitive function should be demonstrated by associated future studies.
