The goal of this study is an exploratory statistical analysis of the university and college library statistics in the Academic Information Statistics System(rinfo.kr) governed of Korean Education and Research Information Service(KERIS) with performance measures based on sustainability. For the goal, we adopt a preprocessing method to develop change-rate variables by considering preceding predictive elements and succeeding performance elements, and to control external factors, such as size and socioeconomic factors. Then we execute a series of factor analyses and multiple linear regression analyses. 13 factors are extracted by the factor analyses and some sets of significant variables affecting the performance measures are identified through the regression analyses. Based on the results, we discuss the problem of out-lier and low correlation between variables. A suggestion for developing new variables is also discussed based on low effect sizes of the developed regression models. We hope that this study contributes to diffuse discussions on statistics system, evaluation, and further library management based on sustainability.

The demand for measures to enhance the safety of maritime transportation is growing internationally, and coastal shipping companies are pursuing sustainability by establishing various maritime safety policies. Increased awareness of the safety management system and safety culture of coastal shipping companies will minimize accidents and increase corporate sustainability. This study empirically analyzed the impact of a safety management system (safety policy, risk management, and safety guarantee) on the corporate sustainability of coastal shipping companies through the mediation of safety culture. The survey questions for each variable were constructed based on previous research and a dministered to 204 employees of coastal shipping companies. Analysis founed that safety policy did not have a statistically significant effect on safety culture, but risk management and safety guarantees had a positive significant effect on safety culture, which in turn had a positive and significant effect on sustainability. Furthermore, we found that safety culture has a mediating effect on the relationship between risk management and safety guarantees and sustainability. Coastal shipping companies thus need to systematize and strengthen risk management and safety assurance to increase safety culture awareness, and increased safety culture awareness can also increase sustainability.

This research attempts to identify N-screen users' motivational and dissatisfying factors in relation to their willingness for continued future use of the service. An on-line survey was conducted (N=558) to reveal five major factors for N-screen use: Medium usability (interface usability and daily usefulness), Socialness (potential for social use with family and friends), Mobility (use without restraints of time and space), Contents (diversity of contents catalogue and related information search), and Habitual use. With exception of Contents factor, four of those factors were proven to be meaningful predictors of the users' willingness for continued future use of N-screen service. Meanwhile, two factors were extracted as the major source for N-screen users' dissatisfaction: Customer service (dissatisfaction associated with the service itself) and Contents (dissatisfaction relating to contents use). The effect of those two dissatisfaction factors was examined. The results show that Contents dissatisfaction, in comparison with Customer service dissatisfaction, was a more powerful predictor for discontinuing of N-screen service use.

Seaports are economically significant infrastructures in terms of dealing with more than 90% of the cargo volume in Korea's international trade. Furthermore, investment costs for constructing ports and the impacts of port industry on national competitiveness lead to the necessity for sustainable port operation. However, the earlier studies dealing with competitiveness and sustainability of the port sector focused on its logistical functions related to port size, operational efficiency, etc. Port competitiveness that considers local community and ecological values as well as the expectations and demands of port users is becoming an important issue in order for ports to cope with volatile external environments while maintaining competitiveness. Therefore, it is necessary to identify port performance indicators and measure their performance in terms of the environmental and social perspectives, as well as the economic perspectives, in order to sustain port development and operations. This paper presents findings from case analyses of SuPorts and PPRISM projects that assist European Union (EU) ports to secure sustainable competitiveness while respecting economic, environmental and social interests between ports and local communities. These projects create port performance indicators with balanced views including not only economic value but also environmental and social values. They measure port performance so port operators can implement these sustainable port practices. This study aims to find the critical factors for sustainable port practices by conducting case analyses of SuPorts and PPRISM projects.

The purpose of this research was to analyze the effect of consumer innovativeness on the evaluation of online fashion advertisement sustainability and on purchase intentions of advertising products. Online survey have been conducted of 573 people who had experience of online advertisements. The data collected from the surveys were analyzed by the factor analysis, the t-test and the multiple regression analysis. the results are as follows: Firstly, it has been identified that the concept of sustainability of online fashion advertisement consists of four sub-elements of the objectivity of advertisement expressions, the non-harmfulness of advertisement expressions, the protection of personal information, and the non-infringement of web use. Secondly, the group that has a higher consumer innovativeness shows a significantly higher experience of online advertisements as well as more many internet use hours than those who have a lower consumer innovativeness. In addition, comparing with the group that shows lower consumer innovativeness, the group who has higher consumer innovativeness shows a significantly higher recognition of the protection of personal information, the non-infringement of web use and the objectiveness of advertisement expressions among the sub-elements of online fashion advertisement. Lastly, the objectiveness of advertisement expressions and the non-infringement of web use significantly affect the intentions of the group that has high consumer innovativeness to purchase advertised products, and the purchase intentions of those who have low consumer innovativeness are significantly affected by the objectiveness of advertisement expressions and the protection of personal information.

Thus purpose of this study is to examine the structural relationship among the LOHAS image of hotel restaurants, customer well-being menu preference, emotional responses, customer satisfaction, and customer loyalty. To test the hypotheses, a survey was conducted of luxury hotel customers in Busan and Seoul. Of the 400 questionnaires distributed 341 was used final analysis. For the hypotheses testing, frequency analysis, reliability and validity analyses SPSS was used while AMOS was employed to examine the relationship among the measured concepts. The results of testing are shown as follows: LOHAS image of hotel restaurants does have a positive effect on well-being propensity, as well as on customer emotional responses. The cooking function factor of well-being propensity results in a negative emotional responses, while the attractiveness factor of well-being propensity brings about a positive emotional responses. Emotional responses positively affect customer satisfaction, which then positively influences customer loyalty. The arising concept of LOHAS in the service industry can help to develop new menu items for LOHAS or well-being oriented customers. In particular, well-being menu propensity and emotional responses may become more important considerations in marketing strategy formation. This thesis provides a theoretical background of LOHAS image, well-being menu propensity, and emotional responses.

Despite the characteristics of public data with various potentials, few studies have been conducted on general users who lack an understanding of data as well as on expansion of the service uses. This study examined which digital-service-quality factors affect the intention to continue using public data services based on the expectation confirmation theory. As a result of the analysis, satisfaction partially mediated between expectation agreement and continued use intention for understandability and efficiency, which were combined as one factor, and completely mediated the relationship between perceived usefulness expectation agreement and continued use intention. It can be seen that the more the understanding and usefulness of the information provided by the service is satisfied, the higher the willingness to use it. Accordingly, it suggested adding an electronic bookmark function and the provision of online community for users to improve the overall quality of services. This study is significant in that it provided evidence on which part to focus on when designing electronic services from the point of view of general users.
