본 연구는 중학교 교육과정에서 수학과 연계된 지구과학 실험 중 지구의 크기 측정을 중심으로 총 30시간 동안 지구과학 교육봉사 활동에 참여한 예비 지구과학교사와 중학생들에게 본 프로그램이 주는 의미를 살펴보고 혁신적 수업으로의 가능성을 탐색해 보았다. 중학교 과학 교과서에 소개된 고대 그리스 시대 에라토스테네스의 그림자 길이를 이용한 지구 크기 측정 실험에서 나타나는 오차를 최소화하기 위하여, 멀리 떨어진 수도권과 지방의 두 개의 중학교에서 삼각비를 이용한 탐구 활동을 수행 한 후, 실측한 자료를 두 학교 학생들이 공유하여 지구의 크기를 최종적으로 계산하였다. 이 과정을 통해 실측 자료를 효과적으로 표현하는 수학적 방법을 배우며, 반복적이고 정확한 자료 획득 과정의 중요성과 어려움을 체험하고, 도출된 결과에 포함된 오차의 원인들에 대해 토론하였다. 본 연구 결과는 학생들이 지구과학 탐구의 특성을 이해하고, 2015 개정 교육과정에서 과학과 수학교과에서 공통적으로 강조하고 있는 교과 역량인 문제 해결력, 사고력, 의사소통 능력을 함양할 수 있는 수학·과학 통합 프로그램 개발에 기초 자료를 제공할 것이다.

Recently, the advancement of information and communication technology(ICT) is expanding the connectivity through Internet of Things(IoT), and the media of connection is also expanding from wire/cable transmission to broadband wireless communication, which has significantly improved mobility. This hyperconnectivity has become a key element of the fourth industrial revolution, whereas the supervisory control network of purification plants in korea is operated as a communication network separated from the outside, thereby lagging in terms of connectivity. This is considered the best way to ensure security, and thus there is hardly any consideration of establishing alternatives to operate an efficient and stable communication network. Moreover, security for management of a commercialized communication network and network management solution may be accompanied by immense costs, making it more difficult to make new attempts. Therefore, to improve the conditions for the current supervisory control network of purification plants, this study developed a industrial security L2 switch that supports modbus TCP(Transmission Control Protocol) communication and encryption function of the transmission section. As a result, the communication security performance improved significantly, and the cost for implementing the network management system using Historical Trend and information of HMI(Human Machine Interface) could be reduced by approximately KRW 200 million. The results of this study may be applied to systems for gas, electricity and social safety nets that are infrastructure communication networks that are similar to purification plants.

Today, the fashion business environment of the 4.0 generation is changing based on fashion technology combined with advanced digital technologies such as AI (Artificial Intelligence), big data and IoT (Internet of Things). “Digital Transformation” means a fundamental change and innovation in a digital paradigm including corporate strategy, organization, communication, and business model, based on the utilization of digital technology. Thus, this study examines digital transformation strategies through the fashion brand Burberry. The study contents are as follows. First, it examines the theoretical concept of digital transformation and its utilization status. Second, it analyzes the characteristics of Burberry’s digital transformation based on its strategies. For the research methodology, a literature review was performed on books and papers, aligning with case studies through websites, social media, and news articles. The result showed that first, Burberry has reset their main target to Millennials who actively use mobile and social media, and continues to communicate with them by utilizing digital strategy in the entire management. Second, Burberry is quickly delivering consistent brand identity to consumers by internally creating and providing social media-friendly content. Third, they have started real-time product sales and services by using IT to enhance access to brands and to lead consumers towards more active participation. In this study, Burberry’s case shows that digital transformation can contribute to increased brand value and sales, keeping up with the changes in the digital paradigm. Therefore, the study suggests that digital transformation will serve as an important business strategy for fashion brands in the future.
