클라이밍 동작을 기본 컨트롤 도구로 활용하는 상호작용 콘텐츠를 클라이밍월에 적용하여 상호작용이 가능한 휴먼케어 콘텐츠로 전환 할 수 있다. 본 논문에서는 클라이밍월을 스크린으로 활용하여, 스크린 위에서 이동하는 아동에게 지속적인 목표와 동기부여 요소를 제공하는 게임형태의 휴먼케어 콘텐츠를 기획한 사례를 소개한다. 또한 기존의 단방향적인 형태의 클라이밍에 클라이밍의 상하좌우 이동을 활용하는 움직임에 대한 상호작용을 제시하는 게임 콘텐츠를 제작하여 실제 환경에 적용한 결과물을 제시한다.

With South Korea entering aging society, the problem of the elderly living alone is aggravating due to increasing health risks associated with social isolation. This should be counteracted by providing them with supports conducive to the recovery of social relationship and effective management of daily activities, such as health checkups, homecare services, chore services, and contents building for information service. This paper presents a human care system implementing miniaturization and portability for the elderly and other care recipients by integrating various contents into recipients' situation perception, direct experience, and sensor modules as a smartphone application in Internet of Things environment to facilitate their health status monitoring.

Due to economic development and advancement of medical science, an aging society where the proportion of the elderly population increases is coming. Korea's aging speed is growing rapidly compared to that of other developed countries. The physical and mental abilities of elderly people with aging are getting worse more and more. They want a kind of auxiliary system in order to mitigate and prevent their weakness. The supplementary system can greatly contribute to improving the quality of life for elderly people. In particular, some devices that include muscle strengthening and cognitive and balance ability enhancement are useful for the most older people. In this paper, we introduce a development of human care contents based rehabilitation equipment to enhance these functions, and present its usability evaluation. The evaluation is conducted for rehabilitation specialists as well as expected users and their results are analyzed.

Super-realistic content technology has recently attracted attention as a core of the "new normal" that can overcome the spatial constraints caused by pandemics. It is moreover the core that allows users in remote locations to meet and engage in various social, cultural, and economic activities based on a network. Content technology is rapidly spreading beyond the existing entertainment area to various industries as an innovative tool that can be used to overcome space-time constraints and improve the productivity of industrial sites, because reality and virtual reality are now super-connected with ultra-low latency. However, existing services such as teleconferencing and tele-collaboration do not provide a level of realism that replaces face-to-face services, and various technical requirements have been proposed to overcome this. The trends in core technologies such as XR twins, hyper-realistic reproduction, sensory interaction, and emotional recognition technology, which are necessary for interactive realistic content that leads to feelings, from reproduction to experience and emotion, are explained. In this article, our aim is to present the future of realistic content that enables human care and can even overcome psychological difficulties such as the "Corona blues".

In the era of the 4th industrial revolution symbolized by the Internet of Things, big data and artificial intelligence, various embedded devices are increasing exponentially. These devices have communication functions despite their low specifications, so the possibility of personal information leakage is increasing, and security threats are also increasing. Embedded devices can have security issues at most levels, from hardware to services over the network. In addition, it is difficult to apply general security techniques because it has characteristics of resource constraints such as low specifications and low power, and the related technology has not been standardized. In this study, we present vulnerabilities and possible problems and considerations in applying SDN to embedded devices in consideration of structural characteristics and real-world discovered cases. This study presents vulnerabilities and possible problems and considerations when applying SDN to embedded devices. From a hardware perspective, we consider the problems of Wi-Fi chips and Bluetooth, the problems of open flow implementation, SDN controllers, and examples of structural properties. SDN separates the data plane and the control plane, and provides a standardized interface between the two, enabling efficient communication control. It can respond to the security limitations of existing network technologies that are difficult to respond to rapid changes.
