  • With the rapid industrialization and the advent of the era of the Fourth Industrial Revolution, the importance of character education is on the rise. The purpose of this study is to develop the Instructional model that can make the school classroom as a democratic learning community based on general classes and naturally realize the character education in addition to the other subject-matter education. A draft of the instructional model was implemented to confirm that the factors of the character education in mathematics could be improved. The toughness index was measured by using the Character Scale for School Mathematics(CSSM) before and after implementation. Based on the results of the measurement, we completed a P (personal) instruction model and a S (social) instruction model that can enhance the factors of the character education in mathematics based on the democratic learning community through the advisory committee.

  • The purpose of this study is to research on usability of Seoul Bike focusing on seoul citizens over-50s. Before the test, I researched Seoul Universal Design Guideline's background, purpose, principle and range through literature review. Then I did two tests based on re-establishment of the existing principle to fit the public service. First, I have noticed that using the service through an application was difficult for seoul citizens over-50s even if they have NEEDS for using Seoul Bike according to the survey. Next, I drew the result from User Task Evaluation Analysis. Due to the low app usability(the main point of the service) and accessibility and usability status was rate low, but the overall service process was comfortable and convenience. I expect this study will be a good resouce for public service design.

  • It's been more than 30 years since global warming by the increase in CO2 became a cause celebre worldwide. Recently the government promulgated Framework Act on on Low-Carbon Green Growth and has been continuously putting much effort into saving energy and reducing carbon dioxide emissions such as an international climate change conference to prevent the increase in CO2. However, because most cities are not planned for energy saving, new cities should be planned as the active energy-efficient urban structure for 'sustainable urban development' from a long-term perspective. This study aims to design a new prototype for the sustainable energy-independent and environment-friendly housing estates which is the nation's new vision in the era of the Fourth Industrial Revolution. A study on the energy-independent site planning and the quantitative standardization of its factor will be conducted.

  • As the fourth industrial revolution begins in earnest, related technologies are becoming a hot topic. Hardware development is accelerating to make the most of technologies such as high-speed wireless communication, and related companies are growing rapidly. Artificial intelligence often uses desktops in general for related research, but it is mainly used for the learning process of deep learning and often transplants the generated models into devices to be used by including them in programs, etc. However, it is difficult to produce results for devices that do not have sufficient power or performance due to excessive learning or lack of power due to the use of models built to the desktop's performance. In this paper, we analyze efficiency using boards with several Neural Process Units on sale before developing the performance of deep learning to match embedded boards, and deep learning accelerators that can increase deep learning performance with USB, and present a simple development direction possible using embedded boards.

  • Since the era of the 4th industrial revolution has been ripe, the use of artificial intelligence(AI) based on massive data is beginning to be actively applied in various fields. However, as the process of analyzing forest species is carried out manually, many errors are occurring. Therefore, in this paper, about 60,000 pieces of AI learning data were automatically analyzed for pine, larch, conifer, and broadleaf trees of aerial photographs and pseudo images in the metropolitan area, and an AI model was developed to distinguish tree species. Through this, it is expected to increase in work efficiency by using the tree species division image as basic data when producing forest change detection and forest field topics.

  • 산업혁명을 거치면서 높은 화석연료를 사용하는 제조업 중심의 산업구조와 많은 자원을 필요로 하는 도시의 집중 현상으로 지구 온난화에 따른 이상기후 발생이 증가하고 있다. 이러한 기후변화는 홍수, 태풍, 폭염 및 폭설 등의 자연재해 발생 빈도 및 규모를 증가시켜 피해가 커지고 있다. 특히 인구 및 시설들이 집중해 있어 도시의 집중 현상은 이러한 재해에 더욱 취약한 구조가 됨에 따라 피해의 규모를 가중 시키고 있는 실정이다. 전 세계적으로 기후변화 문제의 심각성을 인식하고 이를 해결하기 위해 선신국에 의무를 부여하는 교토의정서(1997년) 채택에 이어, 선진국과 개도국이 모두 참여하는 파리협정(2015년)을 채택하였고 2016년 협정이 발효되었다. 파리협정의 목표는 산업화 이전 대비 지구 평균온도 상승을 2℃보다 아래로 유지하고, 나아가 1.5℃로 억제하기 노력하는 것을 강제하는 것으로 2050년까지 탄소 순배출량을 '0'으로 만든다는 탄소중립사회로의 전환이 본격적으로 시작되었다. 본 연구에서는 기후변화로 인한 물부족 및 수실오염과 같은 도시의 수자원 문제 해결을 위해 IoT 기반 센서 및 네트워크 기반 수자원 플랫폼을 개발하였다. 도시 수자원 시설 데이터를 기반으로 대체 수자원 확보 및 수요 중심의 물 관리를 통해 효율적인 물 배분이 될 수 있도록 하였으며 이러한 스마트 물 관리에 따른 대체 수자원 확보 및 효율적 물 배분이 탄소 저감에 미치는 효과에 대해 분석하였다. 연구대상 지역은 세종 6-4구역으로 LID 특화지구로 조성되었으며 1,000 세대의 주민이 생활하는 공동주택이다. 물 순환(LID) 시설에서 확보된 물을 물 공급 시설과 연계하여 공동주택에서 활용함으로써 감소된 상수 사용량을 온실가스 배출량으로 환산하여 탄소 저감량을 계산하였다. 실제 주민들(1,000세대)이 사용하고 있는 상수량 데이터와 전력거래소 온실가스 배출계수를 활용하였으며 물순환(LID) 시설로 확보하여 대체할 수 있는 상수량은 10%로 가정하였다. 연구대상 지역(1,000세대)의 연간 상수공급량은 331,603m3이며, 연간 전력사용량은69,637kWh이다. 온실가스 배출량은 31.963tCO2eq이며, 온실가스 저감량은 3.2tCO2eq로 산정되었다. 추후 LID 시설에 대한 상수 대체량과 온실가스 저감효과 정량화가 필요하다.

  • This study requires SW education that can adapt to the advent of the fourth industrial revolution and the new normal environment of COVID-19 pandemic. Small and powerful smartphones, which have become a necessity in digital society, are designed and applied to create apps with useful apps or artificial intelligence modules that have been trained with data using the App Inventor program as a good teaching tool. After conducting the class in a blended method that combines face-to-face and non-face methods, the survey questioned the technical and cognitive maturity of artificial intelligence and the pros and cons of blended software classes. We also found changes in career orientation, which is intended to explore SW-related talent occupations that require a lot of demand in terms of national development before and after artificial intelligence classes. Significant results were reached in three of the sub-elements. Even in non-face-to-face situations, it is expected that an app vendor software education program using artificial intelligence will be provided to the actual site.
