  • Understanding consumers' being well and stylishly dressed is a key for marketers' success in ever changing fashion industry. The purpose of this study is to identify the antecedents of dressing style. As antecedents, personal values and clothing-related variables were considered: this study included physical appearance, materialism, and individualism as personal values and quality conscious, price conscious, and brand conscious as clothing related variables. It was hypothesized that personal values influence dressing style both directly and indirectly through clothing related variables. Data were gathered by surveying university students in Seoul, using convenience sampling. Three hundred eleven questionnaires were used in the statistical analysis, exploratory factor analysis using SPSS and confirmatory factor analysis and path analysis using structural equation modeling. The results showed that all the fit statistics for the variable measures were quite acceptable. In addition, the overall fits of the model suggest that the model fits the data well. The hypothesized relationship test also showed that individualism among personal values directly influences dressing style and that only price consciousness among clothing-related variables influences dressing style. With respect to the relative importance, individualism showed the largest standardized regression weight. The results suggest effective product, price, and promotion strategies for marketers whose target market is style conscious consumers.

  • Purpose: The purpose of this study was to examine the effects of aquatic exercise on pain, fatigue, physical fitness, disability in ADL, and psychological variables in women with arthritis. Methods: With a quasi-experimental design, 46 women who has arthritis were assigned into an experimental group (n=23), or a control group (n=23). Data were analyzed with SPSS/WIN using descriptive statistics, t-test and ANCOVA. Results: The mean age of the subjects was 60.9 years in the experimental group and 59.8 years in the control group. The pretest scores of the outcome variables were similar between the two groups except fatigue and waist flexibility. After controlling fatigue and waist flexibility, the experimental group showed more improvement than the control group in Rt shoulder flexibility score (F=4.36, p=.04), sit-up score (F=32.34, p=.00), and muscle strength score (F=30.78, p=.00). The score of disability in ADL decreased in the experimental group (F=5.49, p=.02). The depression score decreased in the experimental group (F=12.01, p=.00), and self-efficacy was improved more than the other variables(F=8.88, p=.00). Conclusion: Aquatic exercise is likely to be an effective nursing intervention to improve physical fitness, to reduce pain, fatigue, and disability in ADL, and to enhance psychological functions in women with arthritis.

  • This paper describes an ejector design technique which used for simulating low pressure environment corresponding to high altitude. Also the ejector performance characteristics was investigated according to performance and geometric variables by cold gas flow test. Entrainment ratio, compression ratio and expansion ratio were designated as performance variables and an ejector gap ratio was designated as a geometric variable. A relationship between the performance variables to predict the ejector performance was identified and it was confirmed that the performance variables have much more effective than the ejector gap ratio through the ejector cold gas flow test.

  • In this study, factors that influence water supply capacities of dams are extracted using factor analysis, and multiple regression equations for estimating water supply capacities of dams are developed using the analysis results. Twenty-one multi-purpose dams and twelve Municipal and Industrial (M&I) water supply dams are selected for case studies, and eight variables influencing water supply capacities of dams, namely: watershed area, inflow, effective reservoir storage, grade on amount of M&I water supply, grade on amount of agricultural water supply, grade on amount of in-stream flow supply, grade on river administration, and grade on average rainfall, are determined. Two case studies for multi-purpose dams and M&I water supply dams are performed, employing factor analysis, respectively. For the two cases, preliminary tests, such as reviewing matrix of correlation coefficient, Bartlett's test of sphericity, and Kaiser-Meyer-Olkin (KMO) test, are conducted to evaluate the suitability of the variables for factor analysis. In case of multi-purpose dams, variables are grouped into three factors; M&I water supply dams, two factors. The factors are rotated using Varimax method, and then factor loading of each variable is computed. The results show that the variables influencing water supply capacities of dams are reasonably selected and appropriately grouped into factors. In addition, multiple regression equations for predicting the amounts of annual water supply of dams are established using the factor scores as explanatory variables, it is identified that the models' accuracies are high, and their applications to determining effective storage capacity of a dam during dam planning and design steps are presented. Consequently, it is thought that the variables and factors are useful for dam planning and dam design.

  • The American Concrete Institute (ACI) 318-11 permits the use of the moment magnifier method for computing the design ultimate strength of slender reinforced concrete columns that are part of braced frames. This computed strength is influenced by the column effective length factor K, the equivalent uniform bending moment diagram factor $C_m$ and the effective flexural stiffness EI among other factors. For this study, 2,960 simple braced frames subjected to short-term loads were simulated to investigate the effect of using different methods of calculating the effective length factor K when computing the strength of columns in these frames. The theoretically computed column ultimate strengths were compared to the ultimate strengths of the same columns computed from the ACI moment magnifier method using different combinations of equations for K and EI. This study shows that for computing the column ultimate strength, the current practice of using the Jackson-Moreland Alignment Chart is the most accurate method for determining the effective length factor. The study also shows that for computing the column ultimate strength, the accuracy of the moment magnifier method can be further improved by replacing the current ACI equation for EI with a nonlinear equation for EI that includes variables affecting the column stiffness and proposed in an earlier investigation.

  • Adoption of mobile learning (m-learning) is not new in Malaysian oil and gas industry, with heavy investment into research and development to train the workers. Nevertheless, the low application of learnt skills on the job remains an emergent research area where there is a missing link on the effects of m-learning and effective organisational learning and implication on its training transfer. The result of this quantitative research revealed that all variables in m-learning were found to have a positive relationship with the effective organisational learning, and there is evidence of training transfer as a mediator of the relationship between self-directed learning, training design, work environment and effective organisational learning. However, there were some discrepancies in the extend of training transfer between trainee characteristics and organisational learning. As such, some important issues emerged which challenge the importance of evaluating workers' readiness and transfer for a successful implementation of m-learning towards developing effective organisational learning.

  • A full treatment of damping material is not an effective method because the damping effect is not significantly increased compared to that obtained by an effective partial damping treatment. Thus, a variety of methodologies has been considered in order to achieve an optimal damping treatment. One of the widely applied approaches is topology optimization. However, the high computational expenses can be an issue in topology optimization. A new efficient convergence criterion, reducible design variable method (RDVM), is applied to reduce computational expense in topology optimization. The idea of RDVM topology optimization is to adaptively reduce the number of design variables based on the history. The iteration repeats until the number of design variables becomes zero. The aim of this research is to adopt RDVM topology optimization into obtaining an optimal damping treatment. In order to demonstrate the effectiveness and efficiency of RDVM topology optimization, optimal damping layouts and computational expenses are compared between conventional and RDVM topology optimization.

  • The purpose of this study is to solve the problem of revision or abbreviation of questionnaires based on the previous studies suggested by many existing empirical studies. In addition, this study aims to provide the theoretical basis of the research method which has been variously approached since it presents the methodology that can directly measure the research object. For this purpose, this study proposed a more elaborate analysis method using the differences in perception of individuals who are interested in cognitive research. Specifically, the perception gap(D) can be used as an independent variable, a dependent variable, and a moderating variable. And this study suggested an effective research approach using the measurement of perception difference. The difference of perception suggested that it can be used as a measure to overcome the limitations of existing researches used it as independent variables or mediating variables that measure only one factor of expectation and performance or importance and satisfaction. In addition, it is highly likely that various analyzes on the perception differences, which are the result of measuring target factors for the same person, will be quite effective in the situation where follow-up of respondents is difficult. This study is expected to overcome various limitations reported by empirical studies such as scale utilization problem and follow-up survey difficulty. In future research, it was expected that the limitation of the factor derivation process in the research approach could be complemented by web crawling and text mining of big data analysis.

  • The purpose of this study were to : a) examine the current foodservice management practices by different types of elder-care sites, b)evaluate the attitudes of recipients of meal service programs, and c) provide feedback for the efficient and effective foodservice management of elder-care sites in Korea. A total of 91 elderly congregate sites was analyzed in Survey 1 and opinons of 190 recipients were surveyed in Survey 2. According to the result of meal cost analysis, the meal cost per a day was ranged from ₩728 to ₩5,500. Only 16.5% elder-care sites had one dietitian due to the lack of budges and the isolated geographical location of sites. These results suggested that financial and dystematical supports by the government would be very necessary to meet the goal of nutritional-balanced meal services at congregate sites. The survey results of recipients at sites, the mean of meal satisfaction score was rated 3.63 at the five-point scales. Significante differences were found between dependent variables(food, convenience, atmospere, menu, facility, and service) and independent variables(site type, gender, living years at sites, and health status). Thus, foodservice managers must consider characteristics of participants for menu planning, service, and distribution.

  • The purpose of this study is to investigate the effect and potential problem of before and after technique in cosmetic surgery advertisements. This study would draw the positive and negative aspects in executing before and after technique by segmenting the surgical part(eyes, nose, and breast). And this study compared before and after technique with after technique and doctor(expert) endorser. Independent variables of this study are advertisement technique(before and after/after/doctor) and the kind of surgery(double eyelid surgery/ rhinoplasty/mastoplasty). Dependent variables of this study are general attitude toward advertising, hospital believability, ethical judgement toward advertising, intention to cosmetic surgery. This study is run as $3{\times}3$factorial design with 30 subjects per cell, resulting in a total sample size of 270. The result of this study shows that advertising technique in cosmetic surgery advertisement important variable to mediate the effect. This study found that before and after technique was more effective than any other techniques. Also, this study found that the kind of surgery variable should be considered in the execution of cosmetic surgery advertisement. Therefore, the result suggests that the kind of surgery and advertisement technique should be spontaneously considered by cosmetic surgery clinic and advertising regulation organizations for the effective communication way and consumer protection.
