The present study explored the impact of personality and self-identity on online information acquisition, information transmission and the usage of SNSs. Participants were 180 students, SNS users, from a university in Korea. Among the participants, 171 students completed all surveys. As a results, personality traits such as openness, extraversion, agreeableness, neuroticism were positively related to the SNS usage and information behaviors. Social identity orientation was associated with time spent of SNS and the number of friends whereas collective identity orientation was related to information acquisition. As a result of multiple regression, time spent, openness, agreeableness, collective identity were significant predictors of information acquisition. The number of SNS in use, time spent of SNS, openness, neuroticism were predictors of information transmission. However, as the predictor of information transmission, neuroticism showed inverse relationship with information transmission.

This is a study to examine the factors that affect group-buying social commerce users' repurchase intention. In order to verify research hypotheses, this paper collected data from 396 users who currently use the group-buying social commerce in China. We used the AMOS 22.0 analysis. The results show that value, trust and satisfaction are the strong predictors of repurchase intention. And Information quality, System quality and Service quality are the significant antecedents of value, trust and satisfaction. Finally, perceived value exerts stronger effect on repurchase intention for high-shopping habit customers, where as trust and satisfaction have higher influence on repurchase intention for low-shopping habit customers. Implications and limitations are discussed.

Although mobile banking provides cost-saving opportunities as well as convenient banking experience for customers, today's banks still face challenges when deploying the technology because a good number of customers are reluctant to use mobile banking for personal reasons. This paper is an empirical investigation of the determinants of the intention to use smartphone-based mobile banking services. The determinants are grouped into two categories including personal factors and social influence factors. We conducted an empirical analysis using 751 survey responses collected from present users of mobile banking services. The results of the analysis reveal that all the personal factors have positive relationships with the intention to use mobile banking services. On the other hand, it was found that of the social influence factors, perceived herding behavior has significantly positive relationship with the intention to use smartphone-based services, whereas subjective norm is not significantly related to the intention. We provide practical as well as academic implications of the research findings.

This study attempted to analyze factors influencing S-DMB adoption. The theoretical background of this study is 'Technology acceptance model.' Based on this theory and literature review this study set 5 hypotheses. For this research, a survey was conducted by online research lab. from October 25 to 31. Data were collected from 350 subjects. Complete and useable questionnaires were received from 303 respondents. The result and conclusion are as follow: 'Instant accessibility,' 'service quality,' 'Cost,' 'advertising,' 'perceived easy of use' are significant factors influencing 'perceived usefulness'. 'Compatibility,' is a significant variable influencing 'perceived easy of use'. However, 'self efficacy' and 'innovativeness' are not significant factors influencing 'perceived easy of use.' The result of the analysis showed that most of the hypotheses were verified the same as preceding studies, but some results were different with the result of preceding studies. Therefore, it implies the characteristics of S-DMB different with other IT systems and mass media that were research subject mostly before, and it influences the result of this study as well.

Recently, the trend of open innovation and web 2.0 change the information portal services. The importance of using information demand analysis is emphasized in planning service strategy. The issues of the study are how we can figure out the demand and how we can use it in enhancing service level. This study aims at presenting the result of green technology information users' interests and the service enhancement directions. For the information types, additive functions, open innovation needs, the relation between users' organization, main job title, and the involved technological area are analysed. Among them, the involved technological area of the user is correlated to the needs, so we illustrate the meaning of planning service strategy according to the technological fields. The main contribution of the study can be the customized service strategy proposal using the users' demand which can be different from one technology field to another.

Recently, as voluntary activity has become more widespread, there have been some voluntary activity movements in the provision of library services for people with disabilities. This study aimed to develop a model on voluntary activity in library services for disabled people in public libraries. Survey data collected through three data collection methods showed that volunteer activities in public library services for the disabled were very poor, and recommended the training of library staff and volunteers serving disabled people, the management of educational programs for librarians about the disabled and the dissemination of standardized manuals. From the results of the survey, a voluntary activity model, based on three factors, the aims of library services, the types of the disabilities, and volunteer services including specific sub areas of services, was developed. Finally, this voluntary activity model will contribute to the theory development of library services for the disabled

The ridership and transit systems are influenced by the expansion of metro-rail in Seoul metropolitan area. However, it has been difficult to measure its precise quantitative influences. Also effective policy implementations have been limited due to the lack of practical evidences. Thus an empirical analysis for an operating metro-rail is essentially required. In this regard, this study examines the impact of the Jungang line on transportation system, whose metro-rail block has been recently started new service. The main interest of this study is to find out the changes of ridership and to forecast the ridership changes by the metro-rail service. The results indicate that the effect on auto users is less than that of bus users. The auto demand is decreased by 33.3% and the bus demand by 66.6%. Additionally, its influence on Gyeonggi-do bus was greater compared with that on the Seoul bus. From questionnaire survey, this results could be confirmed. To sum up, the metro-rail gives less influences on auto users, while it gives greater influences on bus users.

This study finds a way to increase the usability of a subway commuter pass. Usability of the commuter pass on a probabilistic statistical model is calculated when the pass is allowed to used in a different mode(bus). A sunk cost of commuter pass is used to reduce the vehicle travels from public transit. 324 people aged 25 to 35 were surveyed and utilized to build a Nested Logit Model on STRADA 3.5 platform. Main results are as follows. First, commuter passes were issued in various forms. Second, the model turns out to be statistically significant in four explanatory variables (discount rate, inter-usablity between modes, forms of payment and periods). Lastly, the more valid on different modes, the more increased of the rail commuter pass.

The study analyzed the determinants of bypass healthcare utilization for hospitals in Seoul, of which phenomenon has rapidly risen since the introduction of KTX in 2004. 203 interviewees who had visited hospitals in Seoul using KTX were analyzed. We found that probability of utilization of inpatient service is increased with statistical significance by visiting hospital for the purpose of disease treatment, being aged over 40, being married and so on. This implies that the government needs to consider policies to support higher-level general hospitals in non-Seoul areas to enhance the quality of healthcare. Also hospital accreditation program and P4P program need to be used to help patients choose hospitals based on the accurate information on the quality of health care.
