This study aims to empirically investigate how users' online engagement behaviors predict their uses of paid contents. To this end, the data from the 2016 Korean Media Panel Survey, which has been conducted annually by the Korea Information Society Development Institute(KISDI), were analyzed. Major findings(N=8.313) were as follows. First, the active type of online engagement(e.g., posting, commenting), which contributes to direct creation of online contents, was the most powerful predictor to explain the DV. On the other hand, relatively passive actions of user engagement(e.g., sharing, endorsing, voting) turned out to have no significant effects on the uses of paid contents, just as personality traits and online privacy concerns did. Based on these results, it is recommended that online contents or platform service providers should try to establish clearly-targeted marketing strategies, after thoroughly collecting and analyzing the data of users' various online behaviors.

Social Networking Service (SNS) is a part of our daily lives, with their positive and negative impacts. This study investigates SNS fatigue in men and women of different cultural backgrounds as well as the relationship between SNS fatigue and the intentions to cease SNS activities. The study results show that during SNS activities, women are more concerned for their reputation; participants with East Asian cultural backgrounds experience burdens with respect to relationships, and participants with Western cultural backgrounds experience fatigue with respect to privacy concerns. No statistical significance was identified between SNS fatigue and the intentions to cease SNS activity; although people experienced fatigue, they did not desire to stop SNS use. This study reveals that culture and gender impacts SNS fatigue, and few people quit SNS despite the fatigue.

Emerging as a strategic domain of the service industry, the drone logistics industry is evolving into a zero effort industry, which realizes smart device service ranging from corporate services to daily customer services. The role of the drone industry is becoming increasingly important in strengthening national competitiveness, as well as corporate competitiveness, beyond the strengthening of product competitiveness. Although drones have various strengths and weaknesses for industries, there are plenty of possibilities for diverse disputes and conflicts due to lack of related laws, regulations, and institutional norms, as well as unsolved problems related to technologies and operations; that is, there are still policy tasks and problems to be solved such as unauthorized seizure of drones, hacking, protection of personal privacy, safety concerns, regulation and limitation of flying areas, damage relief, and dispute settlements. Thus, in order to vitalize the drone industry as a future growth engine while responding to the changes in the environment of the drone industry in Korea and overseas and to strengthen national and corporate competitiveness by harmonizing with advanced management innovations, it is necessary to conduct in-depth discussions and review policy issues related to the vitalization of the drone industry. Therefore, the purpose of this study is to review the domestic and overseas realities and statuses of the drone logistics industry and application cases, analyze policies regarding the drone logistics industry of each country, review general theories on the solution of disputes arising out of the transactions in the drone logistics industry, and, as a conclusion, suggest desirable policy issues for the vitalization of the drone logistics industry in Korea.

Recent advances in Internet of Things (IoT) encourage us to use IoT devices in daily living areas. However, as IoT devices are being ubiquitously used, concerns onsecurity and privacy of IoT devices are getting grown. Key management is an important and fundamental task to provide security services. For better security, we should restrict reusing a same key in sequential authentication sessions, but it is difficult to manually update and memorize keys. In this paper, we propose a hardware security module(HSM) for automated key management in IoT devices. Our HSM is attached to an IoT device and communicates with the device. It provides an automated, secure key update process without any user intervention. The secure keys provided by our HSM can be used in the user and device authentications for any internet services.

Purpose: As declines in the quality of residential environments occur, such as urban heat island effect, tropical night phenomenon, and violations of right to light and privacy due to urban densification and high rise building, these problems are emerging as social issues. In order to improve these issues, design factors which consider environmental aspects must be selected when planning apartment complexes, and ways to reflect them in the planning phase must be explored. Method: In this study, the analytical hierarchy process(AHP) was used to deduce design factors that considered environmental elements during the planning of apartment complexes. Furthermore, the priority and weight for each evaluation index were assessed. The objective was to propose a guideline for planning apartment complexes by finding the best solution for each evaluation index using complex weight values. Result: Floor area ratio was selected as the most important evaluation criterion in the environmentally conscious evaluation index for apartment complex planning. The shape and placement of skylights were selected as the most important evaluation criteria in the sunshine environment for a pleasant residential environment. Ground surface cover design was selected as the most important criterion in the outdoor thermal environment index for improving the microclimate within cities and apartment complexes. Thus, the results of this study can serve as an investigation guideline that concerns policy and regulations, and as reference data that can be used in planning apartment complexes.

Recently smart phones have been proliferating widely and quickly. Since the number of mobile apps that are being developed and deployed to domestic/international app stores is rising, more apps are being installed and deleted by users without any difficulty. The deployed apps are each attested through distinct verification framework of specific app stores. However, such verification frameworks are insufficient in checking security concerns. Unfortunately, the security verification framework is necessary since the incidents of leaking privacy and confidential information are being increased in lately. The aim of this paper is to provide the security verification framework that assures security and reliability of the e-government mobile apps. In order to verify proposed verification framework, a few apps were selected and inspected through proposed framework and these inspection results are included in this paper.
