Recently, there are high expectations of a society benefitting from a digital sharing economy. However, to establish a digital sharing economy, one needs to first create a reliable social structure. Transparency is recognized as the most important measure of value in not just politics or economics, but also in all domains of our lives. Although all nations strive to create "societies based on credit and trust," in truth, rigidity, irregularity, corruption, and inefficiency are widespread in all aspects of society. Thus, there is a growing interest in blockchain technology, also called the "second Internet revolution," seeking trust in digital environments, although it is difficult to obtain trust in such environments. However, the principles and methods of evaluating blockchain technologies are still unclear and not standardized. This study addresses the evaluation indexes such as transaction per second, maximum data size per one transaction, accuracy and blockchain technology application methods in the digital sharing economy and suggest ways to safely vitalize a blockchain-based digital sharing economy.

The aim of this study is to test the behavioral acceptance of adopting smart-media for special education teachers on the points of personal innovativeness and social influence with structural equation modeling(SEM). The corelation of factors such as personal innovativeness, social influence, performance expectancy and behavioral intention are significant. The results of SEM analysis show that the direct impact of social influence on performance expectancy and behavioral intention is significant. The indirect impact of social influence toward behavioral intention through performance expectancy is also significant. However, the personal innovativeness is not statistically significant factor affecting performance expectancy and behavioral intention.

This study analyzes diverse research studies on psychomotricity as convergence of psychological and physical exercises and aims to identify challenges and provide solutions for more extensive future research. The study collected 50 papers published in Korea from 2013 to March 2017 through paper search systems and analyzed the distribution of the works by types and research subjects, and types of research design, types of dependent variables and the number of interventions involved. By research design, it was found that most number of papers were based on single-subject research, followed by quantitative research. Motor development appeared the most as a dependent variable, followed by sociality and emotional behavior. Most number of studies involved 21-30 times of interventions. The changes in the research results were analyzed in the order of sociality, motor development, and behavior change. Future psychomotricity studies need to expand study subjects and diversify research methods and variables, with active follow-up studies contributing to social service by providing comprehensive solutions.

In this Study, Social Network Analysis of IoT related patents in South Korea, China, and Japan was conducted from the viewpoint of patent informatics. To this end, 2,526 patents filed by PCT until December 2019 were investigated up to the subclass level of the IPC code. As a result, in the case of South Korea, representative IPC codes are in the order of G06Q, H04L, G06F, H04W, and the highest frequency of interconnection is H04L→H04W, H04W→H04L, H04W→H04B. In China, the representative IPC codes are in the order of H04L, H04W, G05B, G06Q. South Korea has strong technological convergence centered on the G06Q, while China has strong convergence centered around H04L and H04W. Moreover, in China, H04L and H04W have more diverse combinations than in South Korea in Section A, B, G, and H. In the future, it is necessary to study the diversity of technology convergence of H04L and H04W in China.
