The purpose of this study was to identify the effect of service quality of sport programs in a public sport center on purchasing, customer satisfaction, and trust. The respondents for this study were participants of the center (n=331) located in Nowon-Gu, Seoul in Korea. Respondents consist of 166 males and 165 females. The respondents were over 19 years old and had participated in the sport center program. The study utilized survey instruments by using convenience sampling method. The questionnaire was consisted of service quality, satisfaction, trust, loyalty, customer`s repurchasing intention, and socio-demographic variables. The data were analysed by using SPSS ver 15.0 and AMOS 7.0. Factor analysis, correlational analysis, structural equation model were used where appropriate. Findings are as follows: First, service quality were found to significantly impact on customer satisfaction, trust, customer`s repurchasing intention, and loyalty, Second, it was found that personnel factor significantly influenced on customer satisfaction. Third, customer satisfaction. was found to significantly influence on customer`s trust. Fourth, customer satisfaction. was found to significantly influence on customer`s loyalty. Fifth, customer trust was not found to significantly influence on customer`s loyalty. Sixth, customer`s loyalty was found to significantly influence on customer`s repurchasing intention.

The aim of this work was to enhance the water vapor permeability of bio-polyurethane thin film, whose essential application is as a non-microporous type of film in breathable fabrics, by hybridizing it with nano- and micro-sized titania ($TiO_2$). The bio-polyurethanes were synthesized from 4,4-diphenylmethane diisocyanate (MDI) and a polyol mixture containing polyethylene glycol (PEG) and soybean oil-based polyol, that is, bio-glycols by the hydroxylation of soybean oils upto 25% by weight of bio-polyurethane. We studied the effect of hybridizing the bio-polyurethane films with hydrophilic nano- or micro-sized $TiO_2$ on their breathability by measuring the water contact angle and the water vapor permeability of the films; it was found to significantly enhance the permeability of the bio-polyurethane film. Further, nano-$TiO_2$ was more effective than micro-$TiO_2$ due to the higher surface area resulting from nano particles. On the other hand, it is expected that it would be possible to provide additive functionality to the bio-PU membranes due to photocatalytic effect of nano-$TiO_2$.
