Fine needle aspiration (FNA) is the procedure of choice for evaluating thyroid nodules. It is indicated for nodules >2 cm, even in cases of very low suspicion of malignancy. FNA has associated risks and expenses. In this study, we developed an image analysis model using a deep learning algorithm and evaluated if the algorithm could predict thyroid nodules with benign FNA results.Ultrasonographic images of thyroid nodules with cytologic or histologic results were retrospectively collected. For al

Due to the prevalence of personal health tracking, cases of self-logged data being utilized in the clinic are gradually increasing. However, obstacles to clinicians' ability to further adopt such data-driven medical consultations in the existing workflow remain, such as lack of time and poor interoperability. In this paper, we conducted a workshop to design a clinician interface supporting the integration of data-driven consultation into the existing workflow and investigate the role of the inte

Can a Machine Tend to Teenagers' Emotional Needs?
Junhan Kim, Yoojung Kim, Byungjoon Kim, Sukyung Yun, Minjoon Kim, Joongseek Lee

As teen stress and its negative consequences are on the rise, several studies have attempted to tend to their emotional needs through conversational agents (CAs). However, these attempts have focused on increasing human-like traits of agents, thereby overlooking the possible advantage of machine inherits, such as lack of emotion or the ability to perform calculations. Therefore, this paper aims to shed light on the machine inherits of CAs to help satisfy the emotional needs of teenagers. We cond

By enabling people to track their lifestyles, including activity level, sleeping, and diet, technology helps clinicians to treat patients suffering from "lifestyle diseases." However, despite its importance compared to other lifestyle factors, it is not easy to record food intake consistently. Although researchers have attempted to solve this problem, most have not considered its applicability in the clinical context. In this paper, we aim to (1) understand food-journaling practices and (2) expl

Cyberslacking or Smart Work: Smartphone Usage Log-Analysis Focused on App-Switching Behavior in Work and Leisure Conditions
Youngchan Jeong, Hyelan Jung, Joongseek Lee
SJR Q1International Journal of Human-Computer Interaction

As smartphones can handle work and leisure activities simultaneously, cyberslacking and the collapse of work-life balance are causing social problems. Hence, in this study we analyzed users’ smartphone usage behavior and the transition pattern between work and non-work behaviors using log data collected automatically from an actual site. The collected log data were divided into four types of sessions according to work-related characteristics. No significant difference was found in frequency, usa

DMB 미디어 이용과 틈새시간에 관현 연구
이중식

위성DMB의 상용서비스를 시작으로 국내에 본격적인 모바일-멀티미디어 시대가 도래하였다. 모바일-멀티미디어는, 무선망을 이용한 고화질 영상 재현과 부가된 상호 작용성으로, 기존 음성 중심의 모바일 미디어와 차별화된다. 이렇게 새로이 확산되는 모바일-멀티미디어 이용환경은, 통신산업, 방송산업, 그리고 게임산업에 의해 각기 다른 방식으로 접근되고 있으며, 이 중 DMB는‘방송적 특성’을 가진 접근이라 볼 수 있다. 이 연구의 관심은, 방송 중심의 콘텐츠가 가지는 강력한 시각적 시청 특성이 기 존 모바일 미디어가 형성한 시공간적 이용 특성과 어떻게 타협할 것이냐를 살펴 보는 데 있다. 지난 십여 년 간 우리는 모바일 미디어의 폭발적인 확산을 통해, 개인의 사 회적 시간과 공간 이용에 심대한 변화가 생겼음을 목격해 왔다. 이 중 모바일 미디어 가 개인의 틈새시간(niche time)을 재정의하고, 이를 유용화(useful) 및 유익화 (profitable)한다는 연구는, 모바일 미디어가 고정

챗봇 에이전트 정체성(identity)에 따른 사용자의 인식 및 행동 차이에 대한 연구 - 개인, 기관, 기계 에이전트의 차이를 중심으로

한국HCI학회 논문지

최근 헬스케어 분야에서 지속적인 건강 관리 서비스를 제공하기 위해 챗봇 에이전트를 도입하는 시도가 늘어나고 있다. 하지만 아직까지 챗봇 에이전트 설계에 대한 연구는 인간과 기계라는 구분에 머물러 있어, 에이전트에 대한 신뢰, 친밀감, 행동 변화를 모두 고려해야 하는 헬스케어 영역에서의 챗봇 설계에 활용하기에는 한계가 있다. 따라서 본 연구에서는 인간과 기계라는 구분에서 나아가, 보다 다양한 에이전트 정체성에 따라 사용자의 인식과 행동이 달라지는지 조사하고자 했다. 이를 위해 정체성을 다르게 설정한 3개의 챗봇 에이전트인 의사(개인), 병원(기관), 가상 에이전트(기계)를 제작한 후, 집단 간 설계(between-group design) 방식으로 36명의 사용자를 세 그룹으로 나누어 6일간 챗봇을 사용하며 건강 습관을 기록하도록 하였다. 6일간의 챗봇 사용을 마친 후, 사후 설문 및 인터뷰를통하여 사용자들의 신뢰, 친밀감, 행동 개선에 어떤 영향이 있었는지 살펴보았다. 그 결과 의사와

"I Want to Reveal, but I Also Want to Hide" Understanding the Conflict of Revealing and Hiding Needs in Virtual Study Rooms
Soobin Cho, Joongseek Lee, Bongwon Suh
SJR Q1Proceedings of the ACM on Human-Computer InteractionOA

Since the COVID-19 pandemic, video conferencing platforms have given rise to new virtual activities, such as virtual study rooms where users utilize video to share ambient presence for study motivation. In virtual study rooms, it can be challenging for the users to determine what to reveal and what to hide on camera, as the video needs to strongly convey their presence without revealing more than necessary. In this paper, we investigate the conflicting needs of virtual study room users to reveal

Kong, 인터넷 라디오 플레이어가 가져온 제작관행과 청취행태의 변화
이중식, 윤석훈

2006년 봄에 등장한 ‘인터넷 라디오 플레이어’는 라디오와 인터넷이 결합한 새로운 서비스로 청취자와 제작자에게 라디오 청취의 새로운 환경을 제공하고 있다. 본연구는 KBS의 Kong 서비스 1년을 전후하여, Kong이 가지는 통계적 특성과 게시판이 가지는 상호작용성, 그리고 이러한 상호작용성이 프로그램 제작관행에 어떤 영향을 미치고 있는지를 분석했다. 연구를 통해 Kong의 청취 연령층이 상당히 낮아졌음을 확인할 수 있었고 이들의 라디오 이용 특성도 상호작용적이며 멀티미디어적임을 확인할 수 있었다. 한편 Kong은 인터넷 매체로서 콘텐츠 광역화의 특성을 보여주고 있어 해외와 지방 청취자 비율이 점차 높아져감을 확인할 수 있었다. 또한 기존의 청각 중심의 콘텐츠에서 보고 듣는 라디오로 진화되고 있으며, 보이는 라디오가 가지는 정보 입체성이 청취자와 제작진에게 다르게 인식됨을 확인할 수 있었다. 중요한 점은 Kong 게시판을 통한 상호작용성이 제작에 있어 이미 큰 영향을 미치고 있음을

The rise of small, IoT-related devices and sensors have enabled us to sense and collect data than ever before. In this study, we walk through our attempt of a data-driven approach in collecting behavioral data on television viewing, an activity thought as passive and habitual. We conducted a 14 day experiment with 13 households in the wild using a data logger installed at each house.
