Mobile contents market is growing with the rapid adoption of smart-phones. Online access via mobile compared to PC-based online access, has distinctive service delivery characteristics which are ubiquitous connectivity and contextual offer. In addition, this study includes characteristics which are relatively disadvantageous for mobile services compared to PC-based services. These are response time and supporting non-verbal informations. This study investigates the influence of service delivery characteristics to perceived interactivity and mobile service attitude. The results show that mobile services' ubiquitous connectivity and contextual offer showed a positive relationship with the perceived interactivity of the mobile service. And the response time also showed a positive relationship with the perceived interactivity, but non-verbal information didn't. When the trade-off is met between response time and nonverbal information, mobile service developer should choose response time since it has positive effect on perceived interactivity and attitude.

For indoor mobile robots, the performance of autonomous navigation is affected by a variety of factors. In this paper, we focus on the characteristics of indoor absolute positioning systems. Two commercially available sensor systems are experimentally tested under various conditions. Mobile robot navigation experiments were carried out, and the results show that resultant performance of navigation is highly dependent upon the characteristics of positioning systems. The limitations and characteristics of positioning systems are analyzed from both quantitative and qualitative point of view. On the basis of the analysis, the relationship between the positioning system characteristics and the controller design are presented.

This paper aims to empirically examine how personal characteristics and social influence affect user acceptance of mobile web browsing service. To examine the intention to use mobile web browsing service, we applied the Technology Acceptance Model (TAM) which has been widely used to explain and predict the IT acceptance to this study. This research also includes personal characteristics such as computer self-efficacy, mobile self-efficacy, and personal innovativeness in IT and social influences such as subjective norms, image, and visibility as the external variables of the TAM. The results indicate that computer self-efficacy do not directly influence ease of use, but indirectly through mobile self-efficacy. And the results indicate that mobile self-efficacy and personal innovativeness in IT have direct effects on ease of use. Empirical results also show that subjective norms and image affect usefulness. Additional theoretical and practical implications of these findings are also discussed in the paper.

Recently, with the increasing popularity of smartphones, mobile applications have been being used in various sectors. In these environments, some mobile applications are being made for special purposes. The mobile campus application is one exemplary type of such special-purpose mobile applications, which have unique characteristics that allow only designated users, belonging to a specific group, to access and use relevant knowledge. The aim of this study is to identify and investigate critical success factors of mobile campus applications based on the DeLone & McLean's information systems (IS) success model and to find unique characteristics of mobile campus applications, compared to general-purpose mobile applications. In order to empirically test our research model, 199 samples were collected from students who actually had experience of using the mobile campus application of A university at least once. The findings of the structural equation modeling using SmartPLS 2.0 confirmed the DeLone & McLean's IS success model, with the exception for relationships between service quality and user satisfaction/intention to use. Moreover, the moderating role of sense of belonging to school on the relationships between quality-related factors (i.e., information, system, and service qualities) and success-related factors (i.e., user satisfaction and intention to use) was examined.

Purpose: The purpose of this study is to analyze the deployment characteristics of korean and foreign mobile hospitals and to draw out the advantages and disadvantages based on the movement of patients. Methods: The arrangement and user movement lines of foreign mobile hospitals which were actually utilized, and the arrangements and user movement lines of korean mobile hospitals are compared and analyzed. Based on the results of the comparative analysis, we suggest the optimal placement of mobile hospital in Korea. Results: The recently developed Korean mobile hospitals have made many improvements. However, there is no practical use case for the mobile hospital in Korea, so it is necessary to establish the basis for the mobile hospital development site and the site access considerations. In addition, there is no detailed analysis of the movement of the administrators other than the medical staff, and it is considered that research on safe waste disposal is further needed. Implications: It is highly likely to be used as a basic data to find out the combination method of mobile hospitals that can efficiently deal with disasters through the arrangement and movement analysis of mobile hospitals in Korea and abroad.

This research investigates the characteristics of the mobile social commerce and explores the moderating effects of perceived risk and price sensitivity. This survey targeted consumers in their 20s to 30s who use mobile social commerce applications. We used 261 questionnaires for the final statistical analysis. Descriptive analysis, factor analysis, reliability analysis, and hierarchical regression analysis were applied in the data analysis. The results are summarized as follows. First, characteristics of mobile social commerce are composed of economics, informativeness, entertainment and promotion. Second, perceived risk (which had a negative effect on purchase intention) had moderating effects between perceived risk and economics or entertainment. Third, price sensitivity (which had a positive effect on purchase intention) had a moderating effect between price sensitivity and promotion. This study contributes to the disclosure of the role of perceived risk and price sensitivity as moderating factors between the characteristics of mobile social commerce and purchase intention. Finally, useful implications (both academic and practical) are provided for fashion retail managers.

Purpose: The purpose of this study is to examine the deployment types and characteristics of mobile hospitals with it's historical backgrounds. Methods: Since the disaster can not be classified by country, the scope of the study is to include both domestic and foreign mobile hospitals. In order to minimize the casualties from the field hospitals used at the time of the First World War, which is the mother of mobile hospitals, we analyzed the mobile hospitals which are more compact and changed to the target areas and analyzed the mobile hospitals. Results: Historically, mobile hospitals have been transformed in a way that they are close to the target area and rapidly inject essential elements, and the deployment of wards has evolved to be able to combine in any form with center corridor. In the case of hospitals that can deal with infectious diseases, each treatment room was installed separately to thoroughly separate the copper wire. Implications: As disaster damage increases and incidence increases, field response should be quick. However, research on mobile hospitals, which are indispensable for field response in Korea, has not been conducted in various ways. From the origins of mobile hospitals, the development process is reviewed, and research is carried out to clarify the grounds and backgrounds for the planning of mobile hospitals that are quick and appropriate to the situation in Korea and abroad.
