The Internet of things is the infrastructure that can communicate with each other by exchanging information by installing antennas that can communicate with all things in the world. The reason why the Internet of Things is the core of the Fourth Industrial Revolution is that data is collected through the Internet to be. Technology of things Internet and Trend of Things Internet IoT (Internet of Things) is a concept that enables internet connection and communication between devices equipped with various sensors. It is the core IT trend of lot, technology such as big data, mobile, cloud And to provide information for the development of the industrial environment through research on the importance of the Internet of things, the core of the Fourth Industrial Revolution and the processing and analysis techniques of Big Data. By providing various security measures and future technologies, This study was conducted to contribute to management.

This paper is to understanding the recent research trend of leadership. To this end, it is intended to grasp the research trend of leadership by using foreign academic databases such as SCOPUS and SPRINGER. As a result of the analysis, it was found that a lot of research has been conducted in management, human resource management, organization, etc., which have traditionally been studied. However, in addition to this field, research in the fields of Nursing, Engineering, Computer Science, and Education has been steadily increasing. This shows that the study of leadership is becoming important not only in companies and specific organizations, but also in various disciplines. In particular, as leadership is becoming more important than ever, it is expected that research on leadership will continue to be carried out with interest in many fields.

This study aimed to analyze AI research trends related to elementary, middle, and high school education. To this end, the related literature was collected from the SCOPUS database and the publication period of the collected literature was from 1974 to March 2021, with 154 journal papers and 571 conference papers. Research trends were analyzed based on the co-occurrences analysis technique of 4,521 words of author keyword and index keyword included in these papers. As a result of the analysis, big data, data mining, data science and deep learning were found as the latest research trends with machine learning and there was a difference between elementary, middle and high school education. It can be seen that elementary school had a lot of robot-related research, middle school had a lot of game and data-related research, and high school had various and in-depth research. In discussion, we mapped the top 50 words common to elementary, middle, and high schools with the 'Artificial Intelligence Basics' curriculum of Korean Government and '5 Big Ideas' of the United States Government so that AI research can be viewed at a glance.

This paper reviews electrodeless lamp technology. The lamp has very long life time but very high cost compared to conventional lamps such as fluorescent lamp. For optimizing the overall system in performance and cost power supply as well as lamp is very important. First, the paper describes various electrodeless lamps and its market condition. Then, a lot of circuit technology for constructing the power supply is reviewed and circuit characteristics are discussed

The purpose of this paper was to analyze the development trends of gene therapy. The possibility of technological development and commercialization of gene therapy has been increased along with the success of Human Genome Project. A lot of gene-therapy-based R＆D and clinical trials have been advanced. The US and EU have led the global technological development, and Korea is in early stage although many institutions and firms have participated in this area.

Organic based photovoltaics (OPV) have been received a lot of attention because they are lightweight, inexpensive to fabricate and flexible compare to crystalline Si solar cells. In this seminar, several important progresses in the Polymer PV, such as, formation of bulk heterojunction, development of post annealing technique, tandem cell fabrication will be introduced. In addition that, some efforts to achieve the further improvement in the performance of the Polymer PV will be discussed.

This study aims to investigate research trends relevant to mathematics teachers and discuss implications on professional development of mathematics teachers. For the purpose of this study, we review 156 articles written between 2006 and 2015 related to mathematics teachers. The articles are analyzed using the model of professional growth suggested by Goldsmith, Doerr, Lewis(2014). The model discusses personal domain, external domain, domain of practice, and domain of consequence. In the results of this study, articles focusing on the personal domain of mathematics teachers appear a lot in reviewed ones, whereas studies relevant to external domain or domain of practice of mathematics teachers are relatively small.

We conducted a content analysis of the researches published for a 7-year period (1997-2003) in the Korean Journal of Play Therapy (Korean Association for Play Therapy) and The Journal of Play Therapy (Korean Association of Psychological Rehabilitation for Children). Specifically, we analyzed a total of 156 articles for research contents, instruments, subjects, statistical analytic methods, and references. The results of the study are as follows: First, the principal areas of research activity and publication were specific theoretical review, personality, and adjustment research. Most outcomes, processes, and outcome researches were conducted in a form of case study. Second, typical samples contained 4 to 6 year old children or elementary schoolers. A lot of them were counseling center clients or normally adapted children. Third, 37% of the articles used ANOVA-related statistical analytic methods, and 35% of them used descriptive statistical analytic methods. Lastly, many articles averagely cited foreign references written 11 years prior to domestic references.
