With the entry into an aged society, interest and demand for the elderly are increasing. The rapid increase in the elderly is calling for change in various fields. As the opportunities and desires of the elderly to participate in society increase, research on services suitable for the elderly society is needed. Although the expansion of convenience facilities and improvement of the system are being made to solve problems arising from the elderly society, there are many shortcomings in the increasing demand of the elderly. In addition, due to aging, they have difficulty in living independently and independently due to the decline in their daily life ability and physical function. To solve these problems, the government and local governments provide various services for the elderly. The service for the elderly is provided based on the general characteristics of the elderly, so it has limitations in customized services. In this paper, present a service model using extended information in ICT-based services to complement these problems. Scalable information uses IoT environments to collect information and environmental information for the elderly. Service support using information on the expansion of the elderly shall identify the characteristics of the elderly and support appropriate services when users request services.

This paper proposes a mobile robot platform for education that can experiment with various autonomous driving algorithms such as obstacle avoidance and path planning. The platform consists of a robot module and a remote controller module, both of which are based on the Arduino Nano 33 IoT embedded board. The robot module is designed as a differential drive type using two encoder motors, and the speed of the motor is controlled using PID control. In the case of the remote controller module, a command to control the robot platform is received with a 2-axis joystick input, and an elliptical grid mapping technique is used to convert the joystick input into a linear and angular velocity command of the robot. WiFi and Zigbee are used for communication between the robot module and the remote controller module. The proposed robot platform was tested by measuring and comparing the linear velocity and angular velocity of the actual robot according to the linear velocity and angular velocity commands of the robot generated by the input of the joystick.

In the 4th industrial revolution, the maker movement is spreading around the world with the fusion of advanced technology with product manufacturing. Already in developed countries such as the US and Japan, the emphasis is on maker education that integrates education into traditional makers' movement. Through this, we are fostering young talents who will lead the fourth industrial revolution era. Domestic maker education is mainly performed in the maker space, and is limited to the IT field using Arduino and App-Inventor. Therefore, it has the limitation of fostering IT-oriented makers. Therefore, it is affecting the proliferation of the maker's movement because of the difficulty of participation of the general public. The purpose of this study was to understand the characteristics of maker 's movement and to suggest the direction of Korean maker education. In order to accomplish the purpose of research, we analyzed the case of convergent maker education at D Creation Economic Innovation Center, which combines IT and culture technology. We conducted a case study on maker education(VR production project, electronic publishing, beads craft, leather craft, IoT) which was held from July 8 to August 30, 2017 five times. We conducted interviews with five preliminary makers who participated in all the courses of the education, and five instructors who acted as professional makers with pre- developed questionnaires. The results of the study were derived by applying the Thematic Analysis method after opening the contents of the interview. Based on the results of the study, we could suggest characteristics of Korean makers and future direction of maker education.

Research is underway on services and systems that provide real-time alerts for suffocating gases and potentially explosive materials, but currently smart bend type services are lacking. This study supports real-time identification of explosion hazards due to static electricity in the workplace and immediate elimination of accident occurrence factors, real-time monitoring of worker status and workplace hazards (oxygen, hazardous chemical concentration), and immediate warning and data in case of danger. We propose a method of establishing an accident prevention system through analysis. In this way, various accidents that may occur in industrial sites are monitored using IoT-based intelligent sensor nodes, wireless network technology, data processing middleware, and integrated control system, and real-time risk information at the industrial sites is prevented and accidents are prevented. By supporting a safe working environment, the company can significantly reduce costs compared to post-procurement costs.
