This study aims to develop a sort of expert system to simulate Internet of Things (IoT) service in architectural design alternatives and enhance the simulation performance using building information. The proposed protype system, named iotBIM, visualizes human behaviors and IoT services in a virtual place that is automatically generated from among design alternatives. We use commercial building information modeling (BIM) authoring tool for the development of iotBIM. The decision to develop iotBIM on the BIM platform was made because BIM tools already generate precise 3D models of design alternatives; iotBIM is plugged into the BIM tool as a simulation module. In the midst of the design process, architectural designers can activate iotBIM to investigate and establish IoT services that accord visually with design alternatives. The purpose of this study is to provide a theoretical and technological basis for the ultimate goal of this study.

As the Internet technology of things is developed, a variety of things Internet devices are emerging. Manufacturers of such Internet devices are registering with the IFTTT to control the device so that the user can use the service. However, most object Internet devices are controlled by smartphone applications, so when a manufacturer uses different devices, many applications should be installed and used. In this paper, we design a smart home service remote control that can control various smart home devices in cooperation with IFTTT automated service platform.

2018년 한국의 합계출산율은 0.98명으로 OECD 회원국 중 출산율 1명이 되지 않는 유일한 국가가 되었다. 이에 대한 원인으로 경제적 문제, 맞벌이 부부의 증가로 인한 육아스트레스를 들 수 있다. 때문에 육아스트레스를 줄이기 위해 아이를 보다 편하게 보살필 수 있는 사물인터넷(IoT: Internet of Things) 기술이 접목된 육아용품이 필요하다. 이에 따라 본 논문은 기존의 아기침대에 사물인터넷 플랫폼을 추가하고 각 센서 들의 정보를 수집해 아기의 수면패턴분석 및 수면유도, 시트 온도조절, 시트 등받이 조절, 침대 자동 스윙 및 스윙 세기 조절, 침대 높낮이 조절 등의 기능을 수행하는 사물인터넷 기반의 새로운 육아용품을 개발해서, 부모들의 효율적인 육아 활동을 가능하게 하여 육아스트레스에 대한 부담을 크게 감소시키는 것을 목표로 한다.

In recent years, the Internet of things has grown rapidly and is being used in many fields. The function of an Internet device isto collect information in various environments and to provide useful information to users. Due to recent developments in technology, the kinds of Internet devices are increasing and the prices are getting cheaper. In addition, many open source platforms that are easy to use have been developed and are providing convenience to users. In this paper, wireless data transmission and cloud server system based on ESP-12E NodeMCU module was designed and sensor information collected from Internet devices was transmitted to cloud server through WiFi wireless communication. The collected sensor data was saved by creating channel and field in the cloud server and the data of each field was visualized as a graph.

Some blind spots of information were occurring because important information such as school events, employment information, attendance information, and major school schedules were currently communicated through home communication messages only. To address this problem, an e-Board prototype was designed to incorporate P2P-based Internet of Things technology in a wired and wireless network based on a survey of data on smart education based on the Internet of Things. In each classroom, necessary information, such as school events, was received in real time from the classroom and shared in the classroom. They also want to design an e-Board prototype for Internet of Things-based smart education because they are easily accessible to anyone even if they do not know how to use e-Board.

The Internet of Things is valuable as a means of solving social problems such as personal, public, and industrial. Recently, the application of IoT technology to the healthcare industry is increasing. It is important to ensure reliability and security in IoT-based healthcare services. Communication protocols, wireless transmit/receive techniques, and reliability-based message delivery are essential elements in IoT healthcare devices. The system was designed and implemented to measure body temperature and activity through body temperature and acceleration sensors and deliver them to the oneM2M-based Mobius platform.

As Internet of Things (IoT) technology evolves, IoT devices are being utilized in a variety of fields. However, it has become a new surface of cyber attacks and is affecting industries that did not previously consider cyber breaches. After a intrusion occurs, post-processing and damage spread prevention are important, but it is difficult to respond due to the lackof standards and guidelines. Therefore, in order to respond to such incidents, this paper establishes an incident data collection procedure and presents the data that can be collected to improve the intrusion data acquisition method for general IoT devices. In addition, we proved the efficiency and feasibility of the data collection procedure through experiments.

정보통신기술의 발달은 개인용 컴퓨터나 노트북 컴퓨터와 같은 컴퓨터를 중심으로 이루어진 네트워킹 및 인터넷 환경을 컴퓨터를 포함한 스마트폰, PDA, 휴대용 멀티미디어 기기와 같이 이동이 가능한 소형의 기기를 중심으로 변화시키고 있다. 그러나, 연산, 통신 및 네트워킹 기능이 가능한 소형 장치들은 정보화 기기뿐만 아니라 계량기, 온도계와 같은 일반적인 사물에도 부착될 수가 있다. 사물에 부착된 이러한 소형 장치들은 사물의 정보를 자동으로 획득하게 해주거나 사물간의 통신 네트워크를 통해 정보의 상호 공유가 가능해진다. 이와 같이 사물에 부착된 통신 장치를 이용하여 사물이 네트워크에 연결되거나 사물간에 통신 네트워크를 구성하여 정보를 공유하는 개념 및 기술을 지칭하는 용어로 IoT, M2M 및 사물지능통신 등이 있다. 이러한 네트워크 환경에서는 사람 대 사람, 사람 대 사물뿐만 아니라 사물 대 사물간의 통신 네트워크가 가능해져 모든 객체간의 정보 공유가 가능해지며 이는 미래 유비쿼터스 정보 서비스 사회로 진화하기 위한 필수적인 기술 요소라 할 수 있을 것이다.

The remarkable change in the automobile industry, which is a traditional industrial field, is now evolving into a form of moving toward autonomous functions rather than humans due to various convenience functions and automatic driving or autonomous driving technologies if the person was central when driving the car. This situation is expanding to various industries such as the aviation industry and the drone market, as well as the robot market. The drone market in the aviation industry is being used in various fields due to the unmanned nature of drone operation. Among them, military drones are secret and due to the specificity of technology, details are not disclosed, but as a collection of advanced technologies, they have played a key role in drone development. In this study, the current status of China and the European Union, including the United States, which are major competitors in the drone field, was investigated, and the technologies of major countries were compared and analyzed through the characteristics and operational specifications of the drones currently in operation.

IoT, which can be regarded as an enhanced version of M2M communication technology, was proposed to realize intelligent thing to thing communications by utilizing Internet connectivity. Things in IoT are generally heterogeneous and resource constrained. Also such things are connected with each other over LLN(low power and lossy Network). Confidentiality, mutual authentication and message origin authentication are required to make a secure service in IoT. Security protocols used in traditional IP Networks cannot be directly adopted to resource constrained devices in IoT. Under the respect, a IETF standard group proposes to use lightweight version of DTLS protocol for supporting security services in IoT environments. However, the protocol can not cover up all of very constrained devices. To solve the problem, we propose a scheme which tends to support mutual authentication and session key agreement between devices that contain only a single crypto primitive module such as hash function or cipher function because of resource constrained property. The proposed scheme enhances performance by pre-computing a session key and is able to defend various attacks.
