The programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, but it requires mathematical knowledge and logical thinking skills, so that many local private university and college students with low basic skills are having difficulties learning it. This problem occasionally causes SW-major students to lose interest and confidence in their majors during the introductory course of programming languages; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C-language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C-language, and developed the examples of Scratch for exercising the concepts. In addition, we designed an instructional model, by which the programming concepts are first learned through Scratch and then C-language is taught, and conducted an experiment on the SW-major freshman students of a local private university to verify the effectiveness of the model. In the situation where SW education is becoming common, we expect that this study will help programming language education of security IT students.

The fourth industrial revolution era calls for the ability to solve problems creatively based on basic literacy for technology. These capabilities can be enhanced through the maker education linked to SW education STEM convergence education. Meanwhile, one of the tasks that must be set prior to the maker education is to take an educational approach rather than a tech-centric approach and consider ways to stimulate interest and motivation of the participants. For this purpose, this study developed and applied an engineering-oriented Reading & Maker education program to prospective teachers so that they could participate in active making activities on their own with interest and sympathy rather than simply guiding maker activities. As a result of the study, the results of the maker education recognition survey after the application of the program showed a statistically significant improvement(p<.000).

In the era of the fourth industrial revolution, advanced technologies such as the Internet of Things(IoT) and big data are emerging. However, the level of application of IoT to indoor environment is very weak. Therefore, it is necessary to develop a system for analyzing air pollutants or indoor air quality through real-time monitoring using the IoT. This paper implements a system that measures indoor environmental values using Arduino and various sensors, and stores the information obtained from various sensors into a database of server. The information stored in the server was built as a database and utilized in the ventilation system or air cleaner installed in the home or company's room. In the proposed system, it is possible to check the immediate indoor environmental condition through the LED status display of the monitoring sensor module while reducing the cost of the sensor used to implement IoT technology.

This paper analyzed 'Software Education' of the Practical Arts unit among the six textbooks developed under the 2015 revised curriculum, and provided implications for selection of textbooks, researching curriculum, and developing the next textbook. As a result of analyzing the prior study, it was found that the inquiry analysis was insufficient in the case of the elementary school 'Software Education' unit. the inquiry analysis was insufficient. On the contrary, in the middle and high school textbook research was sufficient. Therefore, we analyzed the contents of the textbook using the Romey analysis method, judging that our children who will live in the era of the Fourth Industrial Revolution need an exploratory textbook. As a result of analyzing textbooks, there was no ideal textbook with inquiring tendencies in all analysis factors, and different analysis factors with high inquiring tendencies were found in each textbook. In the entire textbook, the analysis element with the lowest inquiring tendency was the text, and the highest analysis element was the activity. The analysis factors with the greatest deviation in the evaluation index between textbooks are data and evaluation.

Economy of Communion (EoC) is an emerging economic principle that recognizes the dilemma of traditional perspectives and turns to human centered values and ideas. Furthermore the EoC encompasses all the principles derives from free market economy, ethical norm and social solidarity. This study aims to understand Economy of Communion concepts and its ripple effects under current Korean economy condition which mainly follows Neo-liberalism. Korean economy needs new paradigm to deal with intensifying economical inequality in Korea these days. By understanding EoC's primary value and studying research cases and Sungsimdang, Seokwangsa one of EoC enterprise cases in Korea, this study suggests new economic paradigm. In response to the needs, two important practices should be manifested through fraternity: 1) mutural equity, and 2) dissemination of giving culture. These are construct the economy of communion, which is defined as unique humanism. This study is also expected to suggest new paradigm that establishes new economy system that can cover current economy system's problems.

In the fields of science and engineering, multidisciplinary research is common, and researchers with a diverse range of expertise collaborate to achieve common goals. As the 4th industrial revolution gains currency in society, there is growing demand on talented personnel both with technical knowledge and skills and with communicative skills. That is, future engineers are expected to possess competence in social and artistic skills in addition to specialized knowledge and skills in engineering. In this paper we introduce an emerging field of 3D bioprinting as an exemplary case of interdisciplinary research. We have chosen the case to demonstrate the possibility of cultivating engineers with π-shaped expertise. Building on the concept of T-shaped talent, we define π-shaped expertise as having both technical skills in more than one specialized field and interpersonal/communicative skills. Wtih references to such concepts as trading zones and interactional expertise, we suggest that π-shaped expertise can be cultivated via the creation of multi-level trading zones. Trading zones are referred to as the physical, conceptual, or metaphorical spaces in which experts with different world views trade ideas, objects, and the like. Interactional expertise is cultivated, as interactions between researches are under way, with growing understanding of each other's expertise. Under the support of the university and the government, two researchers with expertise in printing technology and life sciences cooperate to develop a 3D bioprinting system. And the primary investigator of the research laboratory under study has aimed to create multiple dimensions of trading zones where researchers with different educational and cultural backgrounds can exchange ideas and interact with each other. As 3D bioprinting has taken shape, we have found that a new form of expertise, namely π-shaped expertise is formed.
