A Study on the Successful Adoption of IoT Services : Focused on iBeacon and Nearby

Abstract Submitted：January 27, 2015 1 st Revision：February 12, 2015 Accepted：February 17, 2015* 숭실대학교 대학원 경영학과** 숭실대학교 경영학부 교수, 교신저자The purpose of this study is to propose the effective location- based IoT service acceptance model by integrating ELM (Elaboration Likelihood Model) with UTAUT (Unified Theory of Acceptance and Use of Technology). The Partial Least Squares was used to analyze the causal relationships with respect to the effects of central route and peripheral route on acceptance intention.The results shows that central route has more significant impac ts on perceived usefulness than peripheral route and CFIP (Concern for Information Privacy) weaken the relations hip of acceptance intention and perceived usefulness. Our findings indicate some meaningful implications in the accep tance research of IOT services. First, we noted that the easy of use significantly affects the adoption of location- based IoT service. Furthermore, it is important to build the secured mechanism of privacy protection to adopt of locatio n-based IoT service. Second, we tried to attempt the newly integrated approach to technical acceptance using UTAUT’s variables and ELM by Petty and Cacioppo (1986). Finally this research empirically analyzed the adoption case of location-based IoT service which is not well-known yet within our country.

The Evaluation of Administrative Efficiency of the Korean University Using DEA Model

Purpose: The purpose of this study was to evaluate administrative efficiency of the Korean university and to identify the factors which may affect on the efficiency of universities. In addition, last purpose of this study was to compare correlation among administrative, research and education model. Methods: The collected data through Higher Education in Korea were analysed using DEA (Data Envelopment Analysis). Furthermore, in order to provide the better accurate results by removing the bias of the results, this paper implements Bootstrap DEA. It also analyzed the causes of efficiency by Tobit Regression after setting the dependent variable as a proposed efficiency score and compared correlation analysis results be- tween other models. Results: The results of this study are as follows; First, the Korean universities showed low administrative efficiencies. Second, efficiency of national universities are higher than it of private universities. Finally, the administrative and research·education model have statistically significant correlation. However, usually many Korean universities focus their resources on education performance such as employment and rates to attract new students than research performances. Conclusion: This study shows that the administrative efficiency positively affects both research and educa- tional efficiency. Approximately 70% of the Korean universities needs to improve their administrative efficien- cies and to pay attention to enhance their poor services, low-level performances.

Issues and Strategic Approach on Creation of a Global Media Company in Korea

With the saturation of the local market, the domestic media industry is searching for new growth drivers by crossing over to other industries, but due to the limited size of the market, results fail to meet expectations. Despite its strengths in cultural contents, as verified by the Korean Wave Hallyu, and advanced platform services, the industry feels threatened by the entry of global foreign media businesses in the domestic arena. This and the stagnated growth in the local media market are challenges we are facing today. On the other hand, it could prove to be a timely opportunity to transform the existing media industry structure where exporting hardware and terminals is at the heart of a globalized business into a structure based on software and contents exports. Based on such critical thinking, this study examines the current status of media markets, home and abroad, and aims to come up with strategic measures through a discussion on the issues and methods proposed for the globalization of local media businesses from a holistic viewpoint based on ecosystem, M&A and contents.
