  • One of the goals of the new 2015 revised curriculum is to cultivate the creativity of students who will live in the era of the Fourth Industrial Revolution to create new things through diverse ideas and challenges based on basic learning skills. Accordingly, in order to solve the given problems rationally, the convergence problem solving ability that can process and utilize various areas of knowledge and information is becoming important. Therefore, in this study, we designed the integrative education using a 3D printer based on Tinkercad modeling and applied it to the class to investigate the effect on the improvement of computing thinking ability of elementary school students. To verify the contents of the study, two classes of 25 sixth-grade elementary school students were divided into an experimental group and a controlled group. For the experimental group, 12 classes of convergence education programs using a 3D printer were applied for about three months, and the same amount of general curriculum was conducted for the control group. After that, the t-tests were carried out using the pre-post test to measure the effectiveness of the computational thinking ability. After the application of the program, the experimental group showed statistically significant improvement in computational thinking ability, but the controlled group showed no statistically significant difference. The results show that convergence education using the Tinkercad modeling-based 3D printer has a positive effect on the improvement of computing thinking ability of elementary school students.

  • As the role of entrepreneurship has become more important for continuous business growth in a rapidly changing economic environment, numerous studies dealing with entrepreneurship are taking place. However, recent studies has concentrated mainly on business-oriented entrepreneurship which emphasizes corporate efficiency only. While in the era of fourth industrial revolution human resources are more important than corporate efficiency, the existing literature is largely focused on traditional entrepreneurship. Research on humane entrepreneurship has not been rigorous, and there are few studies involving small and medium-size enterprises (SMEs) in particular. The purpose of this study is to fill in this void by investigating the effect of humane entrepreneurship on core competencies of SMEs and the effect of these core competencies on corporate performance. To examine SMEs core competencies and their performance from the perspective of humane entrepreneurship, this study set up traditional entrepreneurship and humane entrepreneurship as variables, and develop research model based on these variables. This study tests 5 different hypothesis using this model. A survey was conducted among CEOs and executives at SMEs in Seoul and Gyeonggido, South Korea from, June 26 to August 1, 2018. A total of 310 questionnaires were analyzed. The results show that both traditional and human entrepreneurship have a positive effect on the core competencies of SMEs, which are core competency factors, and that core competencies positively affect both non-financial performance and financial performance. Moreover, non-financial performance is found to have positive effect on financial performance. Given these findings, this study suggests that humane entrepreneurship is critical to SMEs and their performance, no less than traditional entrepreneurship. This study provides profound implications of necessity of raising humane entrepreneurship in environment of companies.

  • Lee Hang Ro's Mind-theory(心說) is an important theory comparable to it of Gi Jeong Jin, Lee Jin Sang and Jeon Woo. In this paper, I examined the influence of the Western-school(西學) in the process of formation of Lee's theory. Since the Western-school had flowed in the beginning of the 17th century, in the 18th century it was subject to Confucian intellectuals along with social stability. However, listed in the 19th century, along with the turmoil of the East Asian international order, the Western-school was also rejected. The Western-school was a tool to analyze the cause of Western invasion(西勢東漸) in him. Lee saw The Western-school from the standpoint of Christianity mainly. Especially Christianity was recognized as a religion that emphasizes God rather than humans. In contrast, Confucianism was understood as a thought system that emphasizes human moral subjectivity rather than God. In this process mind was expanded to the subjectivity of human. However, Lee only emphasized the traditional Confucianism order and ignored the rationality of the Western-school. He could not accommodate western civilization actively and properly respond to the world order in that time. On the other hand, we are now in the era of a new civilization called the Fourth Industrial Revolution. To this the remarks of Lee's Mind-theory will be an important suggestion point for organizing the new civilization actively.

  • Last year, a new perception of the right to peace on the Korean Peninsula was adopted: DMZ Yanggu Peace Declaration 2021. The Declaration reflects that there is a raising of necessity for a new perception and approach from the perspective of DMZ-related laws, sustainable ecological environment and security. Gangwon is making considerable efforts to make the border area in DMZ as an area of peace by continuously enhancing publicity on the establishment of the 'Peace Special Self-Governing Province'. This study suggests the necessity of a paradigm shift towards the significance of the interkorean border region that it should function as a passage between the South and the North rather than a dam. For, to be renewed as a sustainably developing region through newly constructed flow of communication, the wall of hostility must preliminarily fall dawn. Then a question arises about how Gangwon is, out of other border region, most eligible for the reconsideration of its significance as a border area. The answer relies on the newly established agenda and understandings towards the right to peace in the perspective of founding the policy for the Unification of the Korean Peninsula. Furthermore, the conservation of DMZ ecological environment through enlistment of UNESCO Biosphere Reserve should go hand in hand with the ultimate value of global agenda of the conservation and protection of the environment. The study insists that the peace zone is a prerequisite for the adaption of the era of future-oriented glocalization featured by the Fourth Industrial Revolution. Up to this date, the border area was an area of pain and agony. It is time for Gangwon to be reborn as an area of peace and coexistence. The aim of this study is to point a direction for Gangwon to become a sustainably developing region by illuminating the value of the Gangwon border area as a new area of peace.

  • As the core infrastructure to lead technical innovation for the fourth industrial revolution, economic value and utilizations of radiowaves are increased rapidly. The objectives of this study are to recognize the growing trend of radio stations that transmit information using radiowaves, a limited resource of the country, and to propose developed plans for the radio stations operation system in line with the changing radio technology and use environment. To be specific, the detailed implementation procedures and methods of the system were derived in accordance with the government's plan to convert the complete inspection of radio stations into a SDoC(Self Declaration of Conformity) by the telco. SDoC is a policy that grants autonomy and responsibility for radio waves interference management to existing telecom operator recognized as having radio stations operating capabilities. It has significance in that the function of radio stations inspection, which is a representative technical regulation, is efficiently distributed to the government and the private sector. This study has significance in providing reference for expediting deregulation in the radiowaves management policy.

  • This study conducted an empirical analysis of the factors affecting the job commitment of employees within a financial sales organization, focusing particularly on agile leadership and organizational justice. Agile leadership was subdivided into four components: adaptability, collaboration promotion, proficiency, and an agile approach, whereas organizational justice was broken down into distributive justice, procedural justice, and interactional justice. Data were gathered through an online survey, and 245 valid responses were subjected to hierarchical regression analysis. The results revealed a significant positive effect of distributive justice, interactional justice, adaptability, promotion of collaboration, and an agile approach on job commitment among the employees of the financial sales organization. However, the influence of proficiency, a component of agile leadership, and procedural justice, a dimension of organizational justice, did not prove to be statistically significant. The order of influence among the significant variables was found to be: adaptability, interactional justice, promotion of collaboration, distributive justice, and an agile approach. These findings confirmed the impact of agile leadership in financial sales organizations, traditionally viewed as conservative, and suggested practical implications for the financial sector to adapt in anticipation of the Fourth Industrial Revolution.

  • With the start of the fourth industrial revolution era, technologies of various fields are merged and new types of technologies and products are being developed. In addition, the importance of the registration of intellectual property rights and patent registration to gain market dominance of them is increasing in oversea as well as in domestic. Accordingly, the number of patents to be processed per examiner is increasing every year, so time and cost for prior art research are increasing. Therefore, a number of researches have been carried out to reduce examination time and cost for patent-pending technology. This paper proposes a method to calculate the degree of similarity among patent documents of the same priority claim when a plurality of patent rights priority claims are filed and to provide them to the examiner and the patent applicant. To this end, we preprocessed the data of the existing irregular patent documents, used Word2vec to obtain similarity between patent documents, and then proposed recommendation model that recommends a similar patent document in descending order of score. This makes it possible to promptly refer to the examination history of patent documents judged to be similar at the time of examination by the examiner, thereby reducing the burden of work and enabling efficient search in the applicant's prior art research. We expect it will contribute greatly.
