About the Lab
Professor Jieun Han's research lab focuses on the intersection of healthcare technology, human-centered design, and environmental psychology, with a strong emphasis on smart health environments and assistive robotics. The lab investigates how physical and technological environments—such as smart homes, healthcare facilities, and intelligent robots—can be optimized to enhance user acceptance, well-being, and clinical outcomes. Key research directions include servicescape and healthscape design, usability of healthcare robots, and the application of immersive technologies like virtual reality in neuropsychological assessment and rehabilitation.

15With the COVID-19 pandemic, the importance of home health care to manage and monitor one's health status in a home environment became more crucial than ever. This change raised the need for smart home health care services (SHHSs) and their extension to everyday life. However, the factors influencing the acceptance behavior of SHHSs have been inadequately investigated and failed to address why users have the intention to use and adopt the services. This study aimed to analyze the influential fact
Ever since Bitner defined the term "servicescape" as the physical environment in which the service is assembled, several scholars have attempted to better understand the impact of the built environment in the context of different service settings. While servicescape is a topic of increasing academic interest among scholars and practitioners, most studies in the area are dedicated to understanding the built environment of hedonic service. More studies are needed to examine utilitarian servicescap
BACKGROUND: In neuropsychology, fully immersive virtual reality (VR) has been spotlighted as a promising tool. It is considered that VR not only overcomes the existing limitation of neuropsychological tests but is also appropriate for treating executive functions (EFs) within activities of daily living (ADL) due to its high ecological validity. While fully immersive VR offers new possibilities of neuropsychological tests, there are few studies that overview the intellectual landscape and academi
What is the most significant criteria when you design a healthcare robot? Lots of robots for healthcare environments are being developed, however few of them have succeeded in the real field. Therefore, we tried to present a new perspective to approach this problem. In this paper, we propose a framework that verifies usability by interpreting the robot design from the servicescape perspective. Results of user testing concerning nursing robots was analyzed from four aspects of servicescape: Equip
The results of this study provide empirical evidence linking intelligent healthscape quality, pleasure feeling, job outcomes and job satisfaction derived from a theoretical model of intelligent healthscape quality. These findings further elucidate the significance of the technology embedded physical nurse work environment as well as provide new academic approaches by demonstrating novel applications of a theoretical framework.
Purpose: The purpose of this study was to investigate the effects of oral health education on oral health knowledge, oral health behavior, and oral hygiene status of children from North Korea. Methods: Participants were 32 North Korean children defectors (15 in the education group, 17 in the control group). The oral health education program, including theoretical training and toothbrush training, was done once a week for 4 weeks. Effects of the education program were assessed for oral health kno
This paper seeks to understand Korean national activist Thomas An Chunggŭn's (1879–1910) thoughts on peace and war from a religious point of view. Regarding Itō Hirobumi (1841–1909), the first Japanese resident-general of Korea, as evil, Thomas An resorted to armed struggle and assassinated Itō at the railroad station in Harbin, Manchuria on October 26, 1909 in the name of Korean independence and peace in the East. An's faith in religion served as a driving force in his engagement in national mo
Integrated Nursing Care Service has been conducted in Korea since 2013, and there are several suggestions to enhance the medical staff's efficiency. This research aims to develop a model of intelligent healthscape to delineate ecological constraints of robotic environment. A qualitative study was implemented and video analyses were conducted. To support the main theme, we interpreted environmental elements as smart servicescape we developed. Given that a medical robot service is implemented in c
1885년 4월 5일 호레이스 언더우드(Horace G. Underwood, 1859-1916)가 한국에 첫발을 내디딘 이래 언더우드가 사람들은 한국 근현대사의 순간에 늘 함께 해왔다. 그들은 선교는 물론 교육과 의료 등 여러 분야에서 수많은 족적을 남겼다. 언더우드가의 여성 선교사들 역시 남녀의 접근이 자유롭지 못한 시기에 한국 여성들과 어린이들을 대상으로 의료와 교육, 사회활동 등 다양한 역할을 담당하였다. 릴리어스 스털링 호튼 언더우드(Lillias Sterling Horton Underwood, 1851-1921) 는 1888년 명성황후의 시의로 내한하여 종교의 자유가 아직 허용되지 않았던 시기에다양한 계층의 여성들과 어린이들을 대상으로 의료를 통한 선교 활동을 펼쳤으며 교육과 문서 선교를 통하여 초기 기독교가 뿌리내릴 수 있는 초석을 마련하였다. 1912년 서울외국인학교 최초의 교사로 내한한 에텔 반 와그너 언더우드(Ethel Van Wagoner Underwood, 188
This study investigates the electroencephalogram(EEG) associated with thermal displeasure with a sudden temperature increase. 18 males and 17 females participated in chamber experiment. They stayed in comfortable environment for 30 minutes and moved to uncomfortable environment then stayed for 20 minutes. They answered thermal sensation vote and thermal comfort vote during experiments. Their brainwave were measured for 50 minutes. As results of the experiment, the relative theta power was decrea
The purpose of this study is to evaluate passenger's comfort in subway stations in the summer. Six subway stations in Seoul were selected and a survey was carried out targeting subway passengers. The survey was carried out from <TEX>$12^{th}$</TEX> to <TEX>$28^{th}$</TEX> in August, 2014. The questionnaire of comfort consisted of five environmental factors; thermal, air, light, acoustic and overall comfort and each items consisted of a five-point scale on each comfort. Tablet PCs were used to ma
To make provision for the super-aged society, the senior welfare facility which is a kind of typical physical environment of the nursing service would be expected to perform a very important role in local community. This study was conducted to identify the constructs of the servicescapes of senior welfare facility and to draw analysis indicators of it. For this, we performed literature review based on domestic & foreign government guide, service marketing theory and interior architectural result
