Since in web service composition, the same service may be offered by different providers with different Quality of Services (QoS) attributes, selection criteria are needed to select which Web Services will be considered for composition. Location of provider can be one of these criteria and intends to decrease the number of remote interactions between providers as well as reducing waiting time of service consumer. Therefore in this paper, we present technique for composing web services according to their location by semantically describing customer's goals and provider's web service capability by means of carefully designed ontology and logical expression.

We studied customer recognition and understanding of menu labeling as well as the correlations between customer support for menu labeling and multiple factors, such as demographic characteristics, dinning-out behavior, and menu selection criteria. This study designed a survey and received responses from 351 individuals. The analysis results reveal that most respondents did not acknowledge menu labeling or lacked knowledge of it. Many of the respondents showed experience in ordering from menus with ingredient labels, but many showed no interest in menu labeling. Exactly 114 (32.5%) respondents showed support of menu labeling, and most were interested in levels of trans-fat, fat, and cholesterol. The respondents reported that menu labeling should be implemented more in fast-food restaurants and causal dinning restaurants. This study also analyzed how customer menu selection criteria are related to support level of menu labeling. Respondents were classified into three groups based on their support level for menu labeling (low medium high), after which correlations between customer menu selection criteria and support level were examined. Respondents in the high support group considered all menu selection criteria (i.e., ingredients, health, and consideration of calories). GLM analysis showed that monthly dining-out expenses were highly related to support level with a significance level of 0.05, and the interaction between monthly dining-out expenses and respondents' jobs also affected support level with a significance level of 0.01.

This study provides basic data on how stress impacts the processed convenience foods purchase attitudes and the selection attributes of housewives. The stress consists of 3 factors, which were housework stress, family relation stress and economic stress. The processed convenience food purchase attitude consisted of 2 factors, which were peripheral influence purchase and conviction purchase. The processed convenience food selection attribute consisted of 4 factors, which were quality, convenience, packaging and price. Factor loading confirmation and reliability test were conducted, and the reliability was confirmed with Cronbach's alpha coefficients for all the factors exceeding 0.5. The high stress levels showed significantly high stress factors of housework, family relations and economic stress (P<0.001). The high stress group was shown to make purchases by recognizing peripheral influences (P<0.01). When the selection properties of processed convenience foods depending on different stress levels were examined, it was revealed that among the three groups, the low stress group least considered the price aspect (P<0.01). After deducting the factors, AMOS (Analysis of Moment Structure) was used to conduct the confirmatory factor analysis for verifying validity. The structural equation model was used to determine the path coefficient. From the processed convenience foods purchase attitude, the peripheral influence purchase had significantly positive (+) effects on convenience (P<0.05). Also, conviction purchase was shown to have significantly positive (+) effects on quality (P<0.05). Housework and family relation stress were shown to have negative (-) effects on processed convenience foods selection attribute, and economic stress was shown to have positive (+) effects, although no significant relationships were revealed.

Purpose - The current study examines the shopping behavior of Chinese tourists who purchase Korean cosmetics when visiting Korea, based on expectancy-disconfirmation of shopping satisfaction and brand attitude toward Korean cosmetics. A moderating effect of consumer conformity on the relationships between cosmetics selection factors and two dimensions of disconfirmation - expectation and performance is also examined. Research design, data, and methodology - We conducted a survey with 250 Chinese tourists who visited Jeju, Korea and had purchased Korean cosmetics during their stay. Excluding 43 respondents' inputs because of incomplete answers and missing values, 207 responses were used in the final analysis. All hypotheses were tested using structural equation model (SEM). Results - We found that the Chinese tourist expectations had positive impact on their satisfaction, and the factors for cosmetic selection had a positive effect on shopping satisfaction and brand attitude. A moderating effect of consumer conformity was found to be significant. Conclusions - Given the significantly increased demand for Korean cosmetics from Chinese tourists, Korean cosmetics firms need to better understand cosmetics selection attributes and preference of Chinese tourists, which can provide a guideline to develop retail stores and distribution outlets for Chinese tourists.

This study analyzed the selection factors for cultivation practices in paddy rice farming. For the study, conjoint model with part-worth utility was adopted, where model profiles included three attributes of yield, production cost, and cultivation difficulties and two levels for each attribute. The value of each level was set up with experimental data obtained from National Institute of Crop Science. Ninety three rice farmers, who joined Korea Rural Economic Institute as farmer correspondences, were surveyed through internet with the profiles selected by factorial design. Result showed that rice farmers considered cultivation difficulties as the most important selection factor to adopt new cultivation practices followed by production cost and yield in consecutive order. This results were robust in spite of past experiences with new practices, willingness to adopt new practices in the future, imitative nature and government interventions.
