스마트 거울은 다양한 IT기술을 활용하여 다양한 정보를 제공해 주는 거울이다. 그러나 기존의 스마트 거울은 단순한 정보만을 제공하거나 기존 정보 시스템에 답습에 그치고 있다. 본 논문에서는 기존 스마트 거울의 기능과 함께 사용자 맞춤형 스타일링 가이드 모드를 최적화한 Iot 기반 스마트 거울 시스템을 제안한다. 제안하는 시스템의 스타일링 가이드모드는 헤어 스타일링 방법 추천과 메이크 업 방법 추천, 퍼스널 컬러를 이용한 화장품 색상 추천 등의 다양한 기능을 제공하여 거울의 본질을 극대화 할 수 있도록 한다. 제안 시스템은 스마트 거울이 갖추어야 할 날씨 정보, 대중교통 도착정보, 길찾기, 일정 관리, 사진 촬영 등의 일반적인 기능을 제공한다. 이를 바탕으로 사용자에게 새로운 스타일링의 접근성과 활용성을 높이고, 다양한 미디어 정보를 통한 정보 활용과 외출 시간을 단축하는 새로운 스마트 거울 시스템을 제안한다.

With the development of Internet of Things (IoT) technology, the combination of ICT and medical services has been increasing to improve the quality of medical services. Using the IoTs, we can collect personal health information continuously in a patient's everyday life. We expect that this will improve the quality of medical service through analysis. However, the problem of ensuring the protection of personal information within the personal health information has been hampering the research, development, and application of such services. Other problems include lack of IoT devices and lack of user convenience for collecting health information about a patient's everyday life. Therefore, in this study, we construct a daily health information management service that can collect the health related information at any time and store this data in personal storage. This data is then only provided to the healthcare worker when necessary. We built a test bed for an IoT-based smart home platform and are currently conducting user experiments. Based on the results of this study, we are attempting to provide a high quality medical trial service based on daily health information through linkage with medical device manufacturers, medical clinics, insurance companies, etc. We expect the proposed health information management service will contribute to the revitalization of smart health care services via activating various health related IoT devices and analyzing daily health information.

IoT devices refer to embedded devices that can communicate with networks. Since there are various types of IoT devices and they are widely used around us, in the event of an attack, damages such as personal information leakage can occur depending on the type of device. While the security team analyzes IoT devices, they should target firmware as well as software interfaces since IoT devices are operated by both of them. However, the problem is that it is not easy to extract and analyze firmware and that it is not easy to manage product quality at a certain level even if the same target is analyzed according to the analyst's expertise within the security team. Therefore, in this paper, we intend to establish a vulnerability analysis process for the firmware of IoT devices and present available tools for each step. Besides, we organized the process from firmware acquisition to analysis of IoT devices produced by various commercial manufacturers, and we wanted to prove their validity by applying it directly to drone analysis by various manufacturers.

It is important to develop a digital SOC (Social Overhead Capital) maintenance system for preemptive maintenance in response to the rapid aging of social infrastructures. Abnormal signals induced from structures can be detected quickly and optimal decisions can be made promptly using IoT sensors deployed on the structures. In this study, a digital SOC monitoring system incorporating a multimetric IoT sensor was developed for long-term monitoring, for use in cloud-computing server for automated and powerful data analysis, and for establishing databases to perform : (1) multimetric sensing, (2) long-term operation, and (3) LTE-based direct communication. The developed sensor had three axes of acceleration, and five axes of strain sensing channels for multimetric sensing, and had an event-driven power management system that activated the sensors only when vibration exceeded a predetermined limit, or the timer was triggered. The power management system could reduce power consumption, and an additional solar panel charging could enable long-term operation. Data from the sensors were transmitted to the server in real-time via low-power LTE-CAT M1 communication, which does not require an additional gateway device. Furthermore, the cloud server was developed to receive multi-variable data from the sensor, and perform a displacement fusion algorithm to obtain reference-free structural displacement for ambient structural assessment. The proposed digital SOC system was experimentally validated on a steel railroad and concrete girder bridge.

According to the recent expansion of the network environment, the spread of smart devices is continuously increasing. With the spread of smart devices such as smart phones, smart pads and wearables, changes are taking place in smart technologies and IT convergence technologies. The development of smart technology is a key element of the 4th industrial technology. The Fourth Industrial Revolution expanded the new service-based industry by adding intelligence to residential, industrial and production environments using IT convergence and smart devices. Research on providing various services using smart technologies, such as smart home, smart factory, smart farm, and smart healthcare, is being conducted in variety. In particular, There is a sharp rise in smart homes due to the proliferation of IoT devices and the growth of sensor technology, control technology, applications, data management, and cloud services. Smart home services using smart technology provide residents with convenient, beneficial services and environments. Smart home service has complemented the existing home network service, but there still are flaws to be modified. In other words, the spread of smart devices, the development of service provider-oriented services, and the interlocking of services have limitations in providing services in consideration of user environment and user state. In order to solve this problem, this study proposes a smart home service system that considers the situation of the elderly.

사물인터넷(Internet of Things, IoT) 분야는 모든 기기, 사람, 사물 등이 네트워크로 연결되는 초연결 사회를 지향한다. 이에 반해 전력시스템은 폐쇄망으로 운영되고 있으며, 차세대 전력망이라 일컬어지는 스마트 그리드 환경에서도 개방형 양방향 통신을 기반으로 논의는 되고 있으나, 정보보안 취약성이 높아지고 사고 위험이 증가함에 따라 전력망의 안전성 및 신뢰성 확보에 대한 중요도가 증가하고 있다. 이처럼 초연결 사회를 전력분야에 적용하기 위해서는 적용대상의 정의, 적용방법 등에 대한 기본적인 표준 정립을 통해 IoT 확산 저해요인을 조기에 해소하는 것이 필요하다. 본고에서는 전력 및 에너지 분야에 사물 인터넷을 도입하고 활성화 하기 위해 필요한 에너지 IoT(eIoT) 표준 시스템에 대해 알아본다.

이 논문은 손가방에 탑재 가능한 IoT기반 락킹 시스템으로 SafeBag 시스템을 설계하고 구현한다. 일반적으로 사람들이 자신의 손가방을 잃어버린 경우, 손가방 내부에 있는 가치 있는 물건을 보호하고 특히, 제3자에게 이들 물건을 탈취되는 것을 방지하기 자동으로 손가방이 잠기기를 바란다. 이러한 요구를 이루기 위한 IoT기반 락킹 시스템은 손가방 내부에 작은 크기의 솔레노이드 잠금 장치를 통한 자동 락킹-언락킹 기능과 스마트폰과 연동된 마이크로 컨트롤러를 이용한 제어 기능 등을 가지고 있어야 한다. 이 논문을 통해 설계 구현되는 SafeBag 시스템은 이러한 기능을 탑재함으로써 손가방을 잃어버린 경우 손가방을 자동 락킹함으로써 가방 내부의 물건을 안전하게 보호해 주는 이점을 제공한다.
