We are entering a phase of an aged society. The societal expense on health care for the so called "silver generation", which refer to as those over the age of 65 is increasing. Although many companies provide various services based on information technology for the health of the silver generation, many have pointed out the limits of them, preventing the activation of services. This study tries to develop a new smart health band business model, which is the most common form of healthcare service that reflects the user's desire. To do this, the study will cover the smart health band and the technical functions related to it, as well as the elements of the business model and its content.

The use of Internet of Things(IoT) in smart cities and smart homes is essential. The security of the sensor nodes, which are the core of the IoT, is weak and hacking attacks are severe enough to have a fatal impact on real life. This research is conducted to improve the security of the Internet of Things by developing a lightweight secure communication protocol for the Internet of Things, and to build a safe Internet of Things environment suitable for the era of the 4th Industrial Revolution. It contributes to building a safe and convenient smart city and smart home by proposing key management and identifier development to increase the confidentiality of communication and the establishment of an Internet authentication system.

2020년 7월 정부는 포스트 코로나 시대를 선언하며, 한국판 뉴딜 정책을 발표하였다. 한국판 뉴딜은 디지털인프라 구축, 비대면 산업육성, SOC 디지털화를 기본방향으로 내세웠으며 빅데이터, 인공지능(AI), 사물인터넷(IoT) 등 4차산업 핵심기술의 육성방안을 제시하였다. 최근 인천공항은 한국판 뉴딜 정부정책에 부응하기 위해 인천공항 K-뉴딜 프로젝트를 추진 중이며, 세부 전략과제로 자산관리의 디지털전환을 위한 IoT기반 스마트 자산관리시스템을 구축 중이다. IoT기반 스마트자산관리시스템은 인천공항에 위치한 실내외 이동형 자산에 대해 끊김없는 위치정보를 제공하는 시스템으로 기존 시스템(RFID) 대비 약 4억 원의 인적, 물적 자원을 절감하는 효과를 나타낼 것으로 예상된다. 본 논문에서는 IoT기반 스마트 자산관리시스템의 핵심기술인 실내외 연속측위 스마트 트래커와 네트워크의 구성, 저전력 위치정보 제공방법을 제시한다.

The idea to conduct this study stemmed from the following question: What is the appropriate interpretation of the recent change in the user behavior of radio listeners? For some terrestrial radio programs, traditional listeners who mainly listen to them real-time through terrestrial radio broadcasting has been outnumbered by those who access them on smartphones and other mobile devices in a nonlinear way outside the pre-scheduled time slots of the programs. In the research, how terrestrial radio listeners use the new service called podcasting to access and consume audio content were examined by using Q methodology. As a result, three different types of user behavior and perception were modeled. This shows a prominent change in radio content use, which is moving away from the conventional user behavior pattern of radio content, one of the key media for mass communication in the 20th century. Such a development opens up new opportunities to create the same or even a greater user base compared to the existing one for terrestrial radio programs with the users' newly gained mobile access and to replace current radio content by using podcasting as a new service.

This research is aimed to identify the building factors and deriving the importance of each factor for establishing the smart distribution center in the fourth industrial revolution era. The research methodology used CFPR(Consistent Fuzzy Preference Relations) to effectively extract expert knowledge. Research has shown as principle factors that "Service" is the first factor to be considered as 0.271, followed by "Infra(Warehouse)"(0.254), "Information System"(0.247), and "Equipment"(0.228). And as detailed factors, "Reliability" showed the highest importance as 0.091, followed "Visibility of Information System"(0.076), "Space Advancement"(0.075), "Location"(0.074) and "Satisfaction of service"(0.073). This study has implications in that it has presented an establishment direction for the smart distribution center.

In the era of digital transformation, the transportation underprivileged remains as an underprivileged class without the benefits of technological advances. Electric assist devices for the People with disability are inadequate to provide services suitable for the current traffic environment, although the mobility of the People with disability is improved. In this paper, we develop IoT smart mobility by deriving essential elements through user satisfaction surveys to efficiently move physical distances based on the experience of users using existing electric assistive devices. Based on the data collected through user satisfaction survey, quantitative analysis using TF-IFD and qualitative analysis based on QFD are performed to determine the importance of user requirements. For the evaluation of IoT smart mobility design results reflecting essential functions, usability verification is conducted by forming an expert evaluation team in various fields. In the future, we plan to conduct a service design study that can improve mobility convenience and provide mobility service solutions by designing to provide efficient public services by utilizing IoT smart mobility to the People with disability.

This study investigated effects of elementary school students' use of smartphone upon not only reading but also self-regulated reading. The subject was 6th year students of elementary school. The study investigated the students by smartphone addict self-diagnosis, reading conditions and self-regulated reading test. The findings were: The students' ownership of smartphone and addiction had influence upon reading quantity, reading time and self-regulated reading, and had no influence upon time of use of smartphone. To help elementary school students make use of smartphone correctly and prevent smartphone addiction, the students should be educated at school and home, and also, proper way to teach students how to read books should be researched in the era of smartphone.

In this study, we point out the problem of child and adolescent smartphone addiction, analyze the effects of these smartphone addictions on adolescents, and study how to prevent smartphone addiction. Most young people living in the current era of smartphone have adoption smartphones. Smartphone addiction among adolescents have caused a variety of problems including youth personality, sociality, interpersonal relationships, and depression. We do not only analyze the problem of addiction. We do analyze various problems such as academic stress, family discord, peer relationships, etc. Investigate is not only the situation at risk, but also, it considers its environment. In this research, we presented not only the problem of smartphone addiction in adolescents itself, but also the effects of some problems on adolescents and how to prevent smartphone addiction.
