Due to the development of social networks and smartphones, many different kinds of issues have emerged in business and society. By reflecting these trends, social network sites have appeared and they are recognized as the new concept of sites. The major feature of the social network sites is that the social relationship had been taken to the online space. Social network sites support the formation of a network and offer users the relationship between users offline as well as online. Based on the features mentioned above, users enjoy the benefits using social network sites. These social network sites in the enterprise can be used to form relationships with customers. This study identified the influencing factors as relational benefits and social influence on relationship commitment in social network sites. In addition, we analyzed that how the relationship commitment between users affects user loyalty after their using social network sites. We presented empirical results by utilizing structural equation model with 244 respondents and the significant implications for the academy and the practice with discussions.

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.

This study identified the effect of changes in the riverbed on the benthic macroinvertebrate communities. The benthic macroinvertebrates collected from the surveyed sites belonged to 119 species, 65 families, 20 orders, and 7 classes in 4 phyla. The number of Ephemeroptera, Plecoptera, and Trichoptera (E.P.T) species was 42, 10, and 8, respectively, in the tributary, confluence, and Nakdong River sites. Lotic species (Hydropsychidae) showed a high density at the tributary sites, whereas lentic species (Chironomidae) showed a high density at the confluence and Nakdong River sites. Community analysis showed that the Dominance Index (DI) was 0.54 in tributary sites, and dominance indices increased closer to the Nakdong River sites. The diversity index (H') was inversely proportional to DI. The ratio of Burrowers species (BU) at the surveyed sites increased closer to the Nakdong River sites. Analysis of common species showed 37 species (34.6%) between the tributary and confluence sites and 66 species (51.5%) between the confluence and Nakdong River sites.

This study investigates "commitment" , which is the crucial variable in the study of relationship marketing, because I pay attention to the importance of relationship marketing toward consumers in virtual environment. This dissertation whose main issue is about virtual environment focuses on "commitment" from two perspectives. One is customers′ relationship commitment toward enterprises or corporations through internet sites and the other is relationship commitment between customers. The main purpose is to verify antecedents and consequents which influence relationship commitment toward internet sites (corporations or enterprises) and between customers. The hypotheses are that (1) share values and relationship benefit from internet sites affect relationship commitment toward internet sites (2) share values and interactions between customers affect relationship commitment between customers (3) interactions with relationship commitments toward internet sites and between customers exist (4) these relationship commitments affect future intentions. The subjects are university students who I think get used to using internet. The results indicate that (1) antecedents of relationship commitment toward internet sites and between customers are significantly influential (2) relationship commitment toward internet sites influences relationship commitment between customers, but the effect of relationship commitment between customers on relationship commitment toward internet sites is not significant (3) relationship commitment between customers influences future intentions, but the effect of relationship commitment toward internet sites on future intentions is not significant.

Multivariate statistical approaches to classify sampling sites with measuring their similarity by water quality data and understand the characteristics of classified clusters have been discussed for the optimal water quality monitering network. For empirical study, data of two years (2005, 2006) at the 9 sampling sites with the combination of 2 depth levels and 7 important variables related to water quality is collected in Yongdam reservoir. The similarity among sampling sites is measured with Euclidean distances of water quality related variables and they are classified by hierarchical clustering method. The clustered sites are discussed with principal component variables in the view of the geographical characteristics of them and reducing the number of measuring sites. Nine sampling sites are clustered as follows; One cluster of 5, 6, and 7 sampling sites shows the characteristic of low water depth and main stream of water. The sites of 2 and 4 are clustered into the same group by characteristics of hydraulics which come from that of main stream. But their changing pattern of water quality looks like different since the site of 2 is near to dam. The sampling sites of 3, 8, and 9 are individually positioned due to the different tributary.

Objectives: The aim of this study was to assess the quality of the information and characteristics associated with information packaging, and develop suggestions for how this web site might be improved. Methods: The 50 sites were selected for evaluation. Inclusion criteria for evaluation were the purpose and the popularity of the sites. Two kinds of evaluation tool were employed for the analysis: one that evaluate the quality of information and the design of the web sites, and another that evaluate the covered contents. A scoring system allowed the sites point on yes/no basis on the evaluation items. The association between quality of the web sites on sexuality education and their site characteristics were assessed using ANOVA. Conclusions: Major conclusions were as follows. First, the scope and currency of the selected web sites were found to be appropriate. Second, the authority of the information was found to be the most serious problem of the selected sites. Third, the category of sexual behavior found to be the most frequently mentioned and sexual health was the second. The least mentioned category was personal skills. Finally, sites operated by private organization were found to have more accurate information and better design feature than those operated by public organization and/or individual.
