Purpose: The purposes of this study were to examine the relationship between health belief and exercise compliance among elderly adults at senior centers and to identify factors influencing their exercise compliance. Methods: The subjects of this study were 100 elderly adults who were using senior centers in J City. Data were collected from the 5th of August to the 14th of September in 2014 using a questionnaire about general characteristics, health belief, and exercise compliance. Data analysis included one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple regression using the SPSS/WIN 18.0 program. Results: The mean score for exercise compliance was 3.85 (range 1~5), and for perceived health state 3.17 (range 1~5). The mean score for each of the sub-factors of health belief was 3.89 for benefit, 1.94 for barrier, 3.34 for severity, 2.43 for sensitivity, and 3.65 for exercise self-efficacy (range 1~5). There was a significant correlation between exercise compliance and exercise benefit, and 28% of variance in exercise compliance was explained by exercise benefit in health belief, family history of illnesses, and perceived sensitivity in health belief. Conclusion: To promote exercise compliance among elderly adults at senior centers, exercise programs emphasizing exercise benefit should be developed.

The symbiotic organisms search (SOS) algorithm is an effective metaheuristic developed in 2014, which mimics the symbiotic relationship among the living beings, such as mutualism, commensalism, and parasitism, to survive in the ecosystem. In this study, three modified versions of the SOS algorithm are proposed by introducing adaptive benefit factors in the basic SOS algorithm to improve its efficiency. The basic SOS algorithm only considers benefit factors, whereas the proposed variants of the SOS algorithm, consider effective combinations of adaptive benefit factors and benefit factors to study their competence to lay down a good balance between exploration and exploitation of the search space. The proposed algorithms are tested to suit its applications to the engineering structures subjected to dynamic excitation, which may lead to undesirable vibrations. Structure optimization problems become more challenging if the shape and size variables are taken into account along with the frequency. To check the feasibility and effectiveness of the proposed algorithms, six different planar and space trusses are subjected to experimental analysis. The results obtained using the proposed methods are compared with those obtained using other optimization methods well established in the literature. The results reveal that the adaptive SOS algorithm is more reliable and efficient than the basic SOS algorithm and other state-of-the-art algorithms.

This study compares the benefits for online clothing purchases between Korean and U.S. consumers. A total of 464 usable questionnaires were obtained from respondents who resided in Korea (n=253) and the United States (n=21l). Data were analyzed by descriptive statistics, factor analysis, and MANOVA. For online clothing purchases, the benefit consisted of five factors: product attribute, transaction services, security, country of origin, and brand symbolism. Results showed that the main effect of nationality and gender on the benefit factors were significant; there was an effect of nationality on product attributes, transaction services, and country of origin. Compared with Korean consumer, U.S. consumers were more likely to consider the benefits of product attributes, transaction services, and country of origin for clothing in online purchases. In addition, there was a gender difference in benefit factors of product attributes, transaction services, country of origin, and brand symbolism. Females were more likely than males to consider the benefits for clothing in online purchases. An interaction effect of nationality and gender was not significant in online purchases for clothing. The managerial implications are discussed for global fashion marketing across the countries.

It is difficult to justify an IT investment unless the investment is expected to have a direct impact on a corporation's performance under rapidly changing business environment. It is important to demonstrate the benefit of the investment through a pre-investment assessment process to induce the executive's decision. This paper presents a methodology to assess the investment by analyzing cost and benefit of the investment. This methodology shows tangible cost as well as hidden cost by analyzing total cost of ownership. The methodology also produces ROI by performing cost benefit analysis including financial and non-financial factors. This paper suggests a systematic way to support If investment decision marking process by evaluating the investment objectively.

The purpose of this study were to investigate the relationships between consumer's value and sportswear's benefit sought/attribute evaluation, and to examine how sportswear's benefit sought were influenced by consumers' value and demographic variables. Subjects were 468 males and females in their teens to 30's in Seoul. Consumer's value was classified into four dimensions by using factors analysis: materialism, achievement orientation, traditionalism, and other consciousness. The value of materialism and achievement orientation had positive relations with brand orientation, fashion, appearance attraction, enterprise image, and brand advertisement of sportswear in both male and female. Achievement orientation had, in case of the male, positive relations with economics, practicality, fabrics, and quality of sportswear. In case of the female, traditionalism had positive relations with economics and practicality, and other consciousness value had positive relations with brand advertisement. Materialism was the most important in predicting brand orientation, followed by social class in both male and female. Age was the most important in predicting practicality, followed by achievement orientation in case of the male. Materialism(-) was, in case of the female, the most important in predicting practicality, followed by traditionalism, achievement orientation, and age.

This paper analyzes the correlation between Net Benefit Test (NBT) and System marginal price (SMP), which has a significant impact on the allocation of demand response (DR) resources in resource scheduling and commitment (RSC) process, based on the performance data of the demand resource market which has been established in 2014. Demand resources compete with generation resources in the RSC process, and it is prescribed to use demand resources only when net benefit occurs. Analysis result shows that the larger the SMP than the Net Benefit Threshold Price (NBTP), the more the winning bid of demand response resource was. It is interpreted that the introduction of NBT in DR market is justified. The demand resource market has been steadily growing. It is required to expand the scope of resources up to the small-sized DR, and to expand the functionalities of demand resources not only in the current energy market but also in the reserve market in the future. In order for that, institutional improvements are required.
