신지나,안중호,김태하 한국경영정보학회 2013 Asia Pacific Journal of Information Systems Vol.23 No.3

The principal objective of the work is to confirm the effects of perceived interactivity, trust, and emotion on intentions to use IPTV service. The empirical investigation into IPTV service users suggests that (i) the perception of interactivity should be directly related with trust, (ii) Users’ trust should bolster users’ emotion in a positive or negative aspect, and (iii) such emotion is verified to affect the intention to use IPTV continuously. More specifically, we demonstrate that positive and negative emotions influence user intentions positively and negatively. Additionally, we find that the trust mediates perceived interactivity and emotions, and both trust and emotion mediate the relationship between perceived interactivity and intentions to use IPTV. The work indicates that trust and emotion of users should be considered from IS perspective in an attempt to build the intention to use IPTV. IPTV firms should consider in their IPTV design and offering strategy how to enhance positive emotions for user retention and eventually bolster intentions to use IPTV continuously.

사용자 경험 관점에서 문화 공연의 디지털 트랜스포메이션 사례 연구 - 방탄소년단 온라인 콘서트를 중심으로 -

신지나(Shin, Ji Na),허정윤(Heo, Jeong Yun) 한국디자인문화학회 2021 한국디자인문화학회지 Vol.27 No.1

본 연구는 온라인 라이브 콘서트에서의 사용자 경험 연구를 통해, 문화 공연의 단순한 디지털화를 넘어 디지털 트랜스포메이션이 일어날 수 있는 기회 요소를 발굴하여 온라인 공연에서의 사용자 경험을 향상하고 가치를 제고하는 것을 목적으로 한다. 온라인 공연에서의 라이브 콘서트 관람 동기가 충족되는지 알아보기 위하여 연구 대상으로 방탄소년단의 온라인 콘서트 ‘MAP OF THE SOUL ON:E’를 선정하여 콘서트를 관람한 사용자를 중심으로 온라인 콘서트에 대한 만족 요소, 불만족 요소, 관람 과정의 행동과 경험을 심층 인터뷰를 통하여 조사하였다. 수집한 자료는 질적 연구 방법의 코딩을 활용하여 온라인 공연에서의 사용자 경험 범주를 추출하고, 고객여정지도를 통해 온라인 공연에서의 단계별 사용자의 니즈와 언맷니즈를 도출하였다. 연구 결과, 라이브 콘서트 관람 동기 중 경험성, 실용성에 관련된 하위 범주에 대하여 사용자는 대체로 만족하였으나 상호작용성, 참신성의 동기는 온라인 콘서트를 통해 충족시키지 못하였다. 따라서 상호작용성과 참신성의 동기를 충족시키기 위해 관객과 무대, 관객과 관객 사이에 상호작용이 일어날 수 있도록 연결하는 방안을 중심으로 디지털 트랜스포메이션 전략을 세우는 것이 필요할 것으로 보인다. This study aims to improve the user experience and value in online performances by discovering opportunities for digital transformation beyond simple digitization of cultural performances through research on user experience in online live concerts. In order to find out whether users are satisfied with their motives for attending live concerts in online concerts, I selected BTS online concert ‘MAP OF THE SOUL ON:E’ as a research target and focused on users who watched online concerts. The satisfaction factor, dissatisfaction factor, and behavior and experience of the viewing process were investigated through in-depth interviews. I extracted user experience categories in online performances from data collected using qualitative research methods, and derived user needs and unmet needs through customer journey maps. As a result of the study, users were generally satisfied with the experience and practicality among the motives for viewing live concerts, but the motives for interactivity and novelty were not satisfied at the online concert. Therefore, in order to satisfy the motive of interactivity and novelty, it seems necessary to establish a digital transformation strategy centering on a plan to connect the audience and the musician, and the audience and the audience.

저산소증으로 미만성 뇌피질 손상이 유발된 성인형 스틸병 환아(患兒) 1례(例) 보고(報告)

송인선,신지나,송미진,이정림,Song, In-Sun,Shin, Ji-Na,Song, Mi-Jin,Lee, Jeong-Lim 대한한방소아과학회 2003 대한한방소아과학회지 Vol.17 No.2

저자는 류마티스 관절염의 일종인 성인형 스틸병으로 치료받던 16세 환아의 치료 과정 중 발생한 미만성 뇌피질 손상 1예(例)에 대하여 초기 양방 병원에서의 치료에도 변화가 없었던 운동마비와 정신신경계통의 제반 증상에 대하여 한방적 치료한 결과 호전도가 있었기에 증예보고(證例報告)하는 바이다. 특히 경계정충(驚悸??)을 동반한 불면(不眠)에 대하여 자하차(紫河車) 약철(藥鍼)과 녹용(鹿茸) 약철(藥鍼)을 시술한 것에 대하여서는 지견을 얻었으며 가미온담탕(加味溫膽湯), 양심탕류(養心湯類)의 처방이 유용한 효과가 있다는 결론을 얻었다. 하지만 150일이라는 장기입원 치료에 비해서 전실어(全失語)는 거의 호전을 보지 못했으며 Mental Grade가 GCS 상 12점까지 상승하였으나 일상생활에서의 능동적인 운동능력의 호전에는 한계가 있었다는데서 아쉬움이 남는다. 아직까지 한방 분야에서 성인형 스틸병과 미만성 뇌피질 손상에 대한 연구는 별로 보고된 것이 없었으며, 특히 장기간의 관리가 필요한 마비 질환의 경우 그 평가 척도나 정신계통의 회복에 있어서 연구 및 치료방법이 부족한 듯하며 차후 지속적인 연구가 필요하리라 사료된다. Objective : There were few reports on the treatment of Adult-onset Still's disease and Diffuse cerebral dysfunction. This oriental medical treatment shows the possibility of healing Adult-onset Still's disease and Diffuse cerebral dysfunction, therefore we announce this. Methods : The acupuncture, herbal medicine, herbal acupucture(Jahageo, Nockyong) therapies were applied for treating this patient's chief symptom(chest discomfort, palpitation, rigidity, mentality change, global aphasia, dysphagia, coughing and sputum) Results : 1. Adult-onset Still's disease is a rare systemic inflammatory disorder of unknown etiology, characterised by salmon-colored rash, intermittent spiking high fever, arthralgia and variety of systemic features. This is one type of Juvenile arthritis. 2. Diffuse cerebral dysfunction is an anoxic-ischemic encephalopathy, and most cause of this is the hypoxia caused by hypotention or respiratory distress. 3. After oriental medical treatments, his chief symptoms were improved. Conclusion : The more study about oriental medical treatment on Adult-onset Still's disease and Diffuse cerebral dysfunction is needed.
