통신과 소재, 센서의 발전은 다양한 분야에서, 다양한 제품 개발을 유도하였다. 항로표지 또한 이러한 기술적인 변화의 흐름에 부합하기 위해 다양하게 진화 하고 있는 중이다. 기존에 기술적 측면에서 고려되어 앞으로 상용화 될 것이라 예측했던 각종 장비 및 기술들이 현실에 적용되기 시작하였다. 드론의 경우 택배, 농업, 소방, 해양안전등 다양한 방면에서 개발이 진행되어 상용화 되고 있으며, 자율주행 차량의 경우도 실제로 제품이 출시되어 운전자가 운전대를 조작하지 않고 숙면을 취하는 내용을 언론매체를 통해 종종 접하고 있다. 이러한 기술 및 장비가 과연 얼마나 항로표지에 적용되어 사용되고 있는지 알아보고 향후 나아갈 방향에 대해서 알아보도록 한다.

In the future, robots and drones for the convenience of our lives in everyday life will increase. As a method for controlling this, a remote control or a human voice method is most commonly used. However, the remote control needs to be operated by a person and can not ignore ambient noise in the case of voice. In this paper, we propose an economical attitude information acquisition method to accurately acquire the posture information of the arm in real time under the assumption that the surround drones or robots can be controlled wirelessly with the posture information of the arm. For this purpose, the extended Kalman filter was used to eliminate the noise of the arm position information. in order to detect the arm movement, a low cost MEMS type sensor was applied to secure the economical efficiency of the apparatus. To increase the wear ability of the arm, We developed a compact and lightweight attitude information acquisition system by integrating all functions into one chip as much as possible. As a result, the real-time performance of 1 ms was secured and the extended Kalman filter was applied to acquire the accurate attitude information of the arm with noise removed and display the attitude information of the arm in real time. This provides a basis for generating commands using real-time attitude information of the arm.

Recently, unmanned technologies interest increased. An unmanned boat is not directly on people and radio can be controlled by boat. Used for military unmanned boat was first developed in the United States Navy. In recent years, for hobby, for pesticide application, for water activities, expanding exploration in various ways, including for use. The role of a variety of unmanned boat above, In the case of a variety of unmanned probe of the role of unmanned boat on the boat people who don't be able to come to the vision of the advantage can not be exploring places like blind spot. In this paper, The Blind Spot are explorations of places such as streaming real-time as possible, an unmanned boat using Raspberry Pi that support implementation. Receiver input signals of an unmanned boat to the transmitter under the manipulation of, using smartphones hotspot feature Raspberry Pi and smartphones, network connection. Via Raspberry Pi motion of using real-time streaming using unmanned boat.

With the crisis of the COVID-19 pandemic and the era of the 4th industrial revolution, archaeological heritage education has entered a new phase. This article responds to the trends in the post-COVID-19 era, seeking ways to develop archaeological heritage education and sustainable strategies necessary in the era of the 4th industrial revolution. The program of archaeological heritage education required in the era of the 4th industrial revolution must cultivate creative talent, solve problems, and improve self-efficacy. It should also draw attention to archaeological heritage maker education. Such maker education should be delivered based on constructivism and be designed by setting specific learning goals in consideration of various age-specific characteristics. Moreover, various ICT-based contents applying VR, AR, cloud, and drone imaging technologies should be developed and expanded, and, above all, ontact digital education(real-time virtual learning) should seek ways to revitalize communities capable of interactive communication in non-face-to-face situations. The development of such ancient heritage content needs to add AI functions that consider learners' interests, learning abilities, and learning purposes while producing various convergent contents from the standpoint of "cultural collage." Online archaeological heritage content education should be delivered following prior learning or with supplementary learning in consideration of motivation or field learning to access the real thing in the future. Ultimately, archaeological ontact education will be delivered using cutting-edge technologies that reflect the current trends. In conjunction with this, continuous efforts are needed for constructive learning that enables discovery and question-exploration.
