The light emitting diodes (LED) lighting source’s color element can be easily changed and this can be effectively applied to meet the users’ emotional needs. Thus, there’s an increase in the demand for research that study the relationship between the color element of LED lighting and the user’s emotional response. This research aimed to understand how the lighting’s color affected the experiment participants as they were resting (Experiment Ⅰ; n=18) or working with intense concentration (Experiment Ⅱ; n=18). A total of nine colors of ambient lighting were provided including red, orange, yellow, green, cyan, blue, white and when the lights are out. Also, the user’s emotional effect was evaluated through the following three cognitive levels: first, at the visceral level the electrocardiogram (ECG) and electroencephalogram (EEG) responses were recorded; second, at the behavioral level the user’s ability to memorize English vocabulary and time perception were observed; third, at the reflective level, the users were asked about lighting color through a survey. There are experiments’ results : first, in resting context there was a positive correlation between the behavioral and physiological appropriateness for the context (r= 0.49); second, in attentive context, there was a positive correlation between the behavioral and reflective appropriateness for the context (r= 0.41); third, even the emotional responses to the red and yellow lights were dissimilar, and the responses to cyan and blue were distinctly disparate. The results of this research can apply lighting color as a design element to induce the appropriate emotional response from the user.

공공 서비스 분야에서의 시민 참여를 확대하기 위하여, 다양한 공공 문제를 제보할 수 있는 신고어플리케이션이 운영되고 있다. 그러나 어플리케이션을 이용한 민원 신고를 적극 홍보하고 있음에도 불구하고 사용자 만족도는 상당히 떨어지고 있으며, 실질적이고 지속적인 사용으로 이어지지 않고 있다. 본 연구에서는 이러한 문제의식에 따라 공공신고 어플리케이션의 문제점을 탐색하고 이를 해결할 수 있는 디자인 대안을 제안하고자 하였다. 연구방법 1 에서는 사용자 리뷰를 수집하여 신고어플리케이션의 민원 처리 과정에 따른 문제점을 분석하였으며, 연구방법 2 에서는 사용자에게 어플리케이션을 사용하여 직접 신고를 해보게 함으로써 실제 신고 상황에서의 문제점을 분석하였다. 본 연구의 결과는 신고 어플리케이션의 실질적인 사용을 유도하기 위해서는 어플리케이션의 기능 및 사용성에 대한 문제점 뿐만 아니라, 일상 생활 속에서 자연스러운 신고 행동을 유도하고 신고에 대한 보상과 격려를 강화할 수 있는 근본적인 해결책이 필요하다는 점을 시사한다.

Background : This burgeoning trend, as the nation transitions towards a super-aged society, has lead to an escalating interest in the quality of life of the elderlies. The necessity for emotional care, potentially delivered through advanced Fourth Industrial Revolution technologies like robotics, is increasingly recognized for the elderly. However, there is still a lack of researches that focuses on the aesthetics, which is the key factor that influences face-to-face interaction. This study analyzed which design elements of the AI care robot and feedback elements of the interaction were more involved in building intimacy with the elderly. Methods : In order to lay the groundwork for a basic theory of the research subjects and their emotions, a literature review was conducted to examine elderly people, intimacy, AI care robots, and senses. We selected Hyodol and Dasom robots as samples, and conducted task-based observations and in-depth interviews on design elements and feedback elements, and analyzed them using behavioral frequency analysis and AEIOU methodology. Results : The following factors contributed to triggering intimacy. First, anthropomorphic onscreen character shapes, white and green colors, and fabric were the most intimacy-enhancing materials. Second, among the feedback elements of interaction, smiling and moving facial expressions, childs voice, multi-sensory feedback, dynamic movement, and various movements were the most involved in creating intimacy. Third, Hyodol’s-dols emotional and cognitive types were more involved in intimacy, while Dasoms play and cognitive types were more involved in intimacy. Fourth, Hyodol-dol was found to be a negative factor because of its simple doll-like appearance, while Dasom was found to be a negative factor because of its simple and mechanical movements. Conclusions : As the market for AI care for seniors is changing with the development of AI technology, this study aimed to propose a design direction suitable for seniors using AI care robots. In the future, we hope that this study will be used as a basis for the development and research of AI design for seniors in various fields such as AI care robots and facilities.
헬스케어 빅데이터 유통을 위한 블록체인기술 활성화 방안

At the core of future medicine is the realization of Precision Medicine centered on individuals. For this, we need to have an open ecosystem that can view, manage and distribute healthcare data anytime, anywhere. However, since healthcare data deals with sensitive personal information, a significant level of reliability and security are required at the same time. In order to solve this problem, the healthcare industry is paying attention to the blockchain technology. Unlike the existing information communication infrastructure, which stores and manages transaction information in a central server, the block chain technology is a distributed operating network in which a data is distributed and managed by all users participating in the network. In this study, we not only discuss the technical and legal aspects necessary for demonstration of healthcare data distribution using blockchain technology but also introduce KOREN SDI Network-based Healthcare Big Data Distribution Demonstration Study. In addition, we discuss policy strategies for activating blockchain technology in healthcare.
