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.

기존의 사이버 환경의 보안 기술은 단순히 데이터, 네트워크, 시스템을 보호함으로써 인간의 자산을 보호하는 차원의 기술이었다면, IoT 환경에서 보안 기술은 궁극적으로 사물들로부터 사람을 보호하는 기술로 패러다임의 변화가 예상된다. 따라서 본고에서는 미래의 새로운 성장동력으로 부상하고 있는 사물인터넷(IoT) 서비스 활성화를 지원하는 동시에 인간의 자산과 생명을 보호하기 위하여 정부차원에서 수립한 정보보호 기술 개발 계획을 정리한다. IoT 정보보호 기술은 디바이스, 네트워크, 서비스/플랫폼의 3개 계층으로 나누어 9개 원천기술로 분류하였다

The purpose of this study is to determine how the use of retailtech technology affects consumers' purchase intention. Furthermore, this study aims to investigate the mediating effects of technology usefulness and ease of use on this influence relationship and whether experiential marketing moderates consumers' purchase intention. The survey was conducted from August 1, 2023 to September 30, 2023, and a total of 257 people participated in the study. For statistical analysis, hierarchical regression analysis, three-stage mediation regression analysis, and hierarchical three-stage controlled regression analysis were conducted to test the hypothesis. The results of the study are as follows. First, it was confirmed that big data-AI utilization, mobile-SNS utilization, live commerce utilization, and IoT utilization affect purchase intention in retail technology utilization. Second, technology usefulness has a mediating effect on IoT utilization, mobile-SNS utilization, and big data-AI utilization. Third, perceived ease of use of technology mediated the effects of IoT utilization, mobile-SNS utilization, live-commerce utilization, and big data-AI utilization. Fourth, escapist experience has a moderating effect on mobile SNS utilization and live commerce utilization. Fifth, esthetic experience has a moderating effect on mobile-SNS utilization and big data-AI utilization. Through this study, we hope that the domestic distribution industry will contribute to national competitiveness by securing the competitive advantage of companies by utilizing new technologies in entering the global market.
