In this paper, as a proposal to an effective corpus construction and utilization scheme, there is a purpose to explore the present situation of Japanese corpus construction, concrete content and current trend. In Japan, dependence on google is remarkable, there has been a steady effort to develop high-quality corpus and development tool. On the other hand, the Japanese corpus should clearly grasp the location and information from those created by individual researchers to their own purpose to those created mainly by universities, research institutes, national policy institutions, etc. It is difficult. In this survey, it was possible to distinguish by "media corpus", "literary·magazine·web and balanced corpus", "spoken language corpus", "learner corpus", "historical material corpus" etc. by field and type. In addition, there were not many tools developed for corpus efficient use and secondary processing such as "example search", "morphological analysis", "machine translation", etc. for tool corpus only. The current trend in Japanese corpus construction spurred preparations for Seed data which can be utilized in linguistic research and various fields of the fourth industry, including national policy and research institutes such as NINJAL, JPO, NICT, ALAGIN and companies such as RAKUTEN ing.

In the 4th Industrial Revolution, it is a time when all the devices and people interact to create new added value. Software education is necessary in elementary school because what is more important is software. However, until now there is a lack of teaching and learning methods for software education in elementary school. In this paper, IDOL model is proposed as a method to solve this problem. statements for elementary students. The idol model is learning through observe, to implement, to diversify. In the implementation, the elementary students are to make it quickly, In the diversification, it is variously changing the things that have been made, and observation how the changed things are different. A model is verified by a group of experts consisting of elementary school teachers.

With the recent start of the 4th Industrial Revolution, markets related to autonomous driving are rapidly developing. In order to understand the rapidly developed technology trend of autonomous driving technology, we would like to investigate the characteristics and differences of level 0 to level 5 of autonomous driving. The overall configuration, recognition technology, and auxiliary technologies of autonomous vehicles are analyzed, and through this, the structure and algorithm of autonomous driving technology are identified. In addition, by manufacturing a simulated autonomous RC car using an ultrasonic sensor and a camera, the necessity of recognition technology and auxiliary technology is identified.

The Green New Deal policy was established to innovate the government's energy consumption structure, establish a third basic energy plan to strengthen the global competitiveness of the energy industry, and realize a carbon neutral society due to the increased need for transition to a low-carbon economy. Waterworks such as drinking water, water purification plant, and pressurization plant analyze control factors and energy consumption status by process to improve energy management efficiency and reduce energy usage through the 4th industrial revolution. Ultimately, we want to realize net-zero water purification plant.

Recently, artificial intelligence and SW have occupied an important position worldwide as the foundation technology of the era of the 4th industrial revolution, and web browser-based programming learning systems are becoming common due to changes in the learning environment caused by COVID-19. In accordance with this trend, this paper proposes a functionally scalable microservice-based system structure for an online evaluation system as a tool for learning algorithms that are the basis of artificial intelligence and SW. In addition, a functional structure for applying machine learning to automatic evaluation functions under the proposed system structure is also proposed.

The academic library has the ideal environment as a facilitator of knowledge creation, as a space where researchers can collaborate and as a creation hub center on campus. Recently, based on the 4th Industrial Revolution and creative theories, the maker space is gradually being introduced into academic libraries in foreign countries. Maker Space of the academic library is the best place to discover new knowledge and interests, practice, and interdisciplinary education. In this study, we propose a plan to introduce the maker space of domestic university libraries through case studies of domestic and overseas university and university libraries.

In this study, city gas is the most commonly used in homes, and gas accidents are increasing as demand increases. Among them, accidents due to user carelessness are the most and we try to provide information by establishing scenarios to effectively prevent this. The gas leak in the home is an enclosed space, and the appropriate Gaussian model is applied. As smart home control technology is developed by the 4th industrial revolution, it will make a foundation to provide information through program to predict and prevent gas leakage accidents and apply it to smart home safety platform.

As IoT technology develops along with the 4th industrial revolution, gas safety products to which IoT technology is applied are being developed. However, since the gas safety system was not allowed, system improvement and operation reliability test for IoT gas safety products are required. This thesis researches IoT fuse cock and smart multi-function meter among IoT gas safety products, and analyzes the empirical data of IoT fuse cock to secure operational reliability data, thereby becoming a leader in IoT gas safety products. It aims to develop gas barrier technology one step further through various test evaluations and methods in the future.

Among the 4th Industrial Revolution technologies, evaluated bolus applicability through dose assesment according to the materials of 3D printing technology. Dose assesment was using MCNPX which was applied Monte Carlo method and 3D print materials were ABS, PC and PLA. Thus, the thickness with the same effect as the bolus 10 mm was found to be ABS 10 mm, PC 9 mm and PLA 9 mm for the 6 MeV electron. For 6 MV X-ray, ABS 11 mm, PC 10 mm and PLA 9 mm were shown. This study showed that tissue equivalent materials made from 3D printer materials can replace bolus.

In modern society, the use of the image processing field is increasing rapidly due to the 4th industrial revolution and the development of IoT technology. In particular, edge detection is widely used in various fields as an essential preprocessing process in image processing applications such as image classification and object detection. Conventional methods for detecting an edge include a Sobel edge detection filter, a Roberts edge detection filter, a Prewitt edge detection filter, Laplacian of Gaussian (LoG), and the like. However, existing methods have the disadvantage of showing somewhat insufficient performance of edge detection characteristics in a low-light level environment with low contrast. Therefore, this paper proposes an edge detection algorithm based on contrast analysis to increase edge detection characteristics even in low-light level environments.
