health news articles, and associated article content and context data. News articles with high informational utility and positive sentiment invited more frequent selections and retransmissions. Articles were also more frequently selected when they presented controversial, emotionally evocative, and familiar content. Informational utility and novelty had stronger positive associations with e-mail-specific virality, while emotional evocativeness, content familiarity, and exemplification played a l

This study investigated psychological mechanisms underlying the effect of narrative health communication on behavioral intention. Specifically, the study examined how exemplification in news about successful smoking cessation affects recipients' narrative engagement, thereby changing their intention to quit smoking. Nationally representative samples of U.S. adult smokers participated in 2 experiments. The results from the 2 experiments consistently showed that smokers reading a news article with

This study examined how content characteristics of antitobacco messages affect smokers' selective exposure to and social sharing of those messages. Results from an experiment revealed that content features predicting smokers' selection of antismoking messages are different from those predicting whether those messages are shared. Antismoking messages smokers tend to select are characterized by strong arguments (odds ratio = 2.02, P = .02) and positive sentiments (odds ratio = 3.08, P = .03). Once

Effects of violent video games on aggression remain contentious despite decades of empirical investigations. Using eight-wave panel data collected from 662 South Korean adolescents (grades 4, 7, and 10) for a 4-year period (number of observations = 5,296), the current research critically tested competing hypotheses concerning the relations between violent video games and aggression. In so doing, we directly compared the results from dynamic fixed-effects (FE) regression with those from conventio

본 연구는 인터넷 정치 토론의 담론적 특성을 알아보기 위해 2004년 국회의 대통령 탄핵 소추 의결 당시 인터넷 포털 다음(Daum)에서 벌어진 정치 토론을 분석했다. 특히 툴민(Toulmin, 1958)이 제시한 비형식적 논변구조 모형을 근거로 인터넷 정치 토론의 전반적 논변구성 방식을 검토했다. 또한 게시판 토론에 나타난 담론의 이야기 구조(narrative structure)의 채택과 토론자의 정서(emotion) 표출 방식에 대해서도 탐색했다. 이는 정치적 사안에 대한 논의에 있어서 토론자의 ‘이야기 구조(narrative)의 채택’과 그에 따른 주관적인 ‘정서의 표출’이 인터넷 토론의 비형식적 논변의 핵심요소를 구성한다고 보았기 때문이다. 연구결과, 인터넷 토론은 비형식적 논변구조를 활용하는 특성을 보이며, 이야기를 주장의 근거로 채택하는 경우가 많으며, 전반적으로 이성적이라기보다는 감성적인 주장을 전개한다는 것을 발견했다. 연구결과가 숙의 민주주의의 관점에서 주장되는 시민

This study examined (a) what message variations characterize news articles that fact-check (mis)information (N = 914) and (b) how those message features shape audience engagement with the articles. The study content-analyzed fact-checking coverage from major news outlets in South Korea using both manual and computerized coding, focusing on three categories of message characteristics: source transparency, contextual information, and vividness. The content-analysis data were examined in relation t

This study investigated how content and context features of headlines drive selective exposure when choosing between headlines of a monthly e-mail health newsletter in a naturalistic setting over a period of nine months. Study participants received a monthly e-mail newsletter and could freely open it and click any headline to read the accompanying article. In each e-mail newsletter, nine headlines competed with each other for selection. Textual and visual information of the headlines was content

이 연구는 2004년 국회의 대통령 탄핵 소추 국면 당시 인터넷 포털 사이트 게시판에서 이루어진 토론 자료를 바탕으로, 인터넷 정치 토론의 담론적 특성을 탐색했다. 이를 위해, 먼저 ‘이야기 주제 구조’ 분석방법을 통해 인터넷 정치 토론 게시글의 이야기구조를 경험적으로 분석했다. 또한 ‘이야기의 구조적 복잡성’이 게시글의 품질을 반영한다고 보고, 이것이 작성자의 다양한 개인적 특성 및 게시글의 의사소통 효과와 어떤 관계를 맺고 있는지 탐구했다. 연구 결과, 첫째, 2004년 포털 게시판 토론에서 ‘탄핵은 정당한 심판’, ‘탄핵은 적법한 과정’, ‘정치 냉소’, ‘탄핵은 부정의’, ‘허탈함ㆍ무력감’ 등 다섯 가지의 이야기구조가 발견되었다. 둘째, 이야기의 구조적 복잡성이 높은 토론자들은 의사소통능력과 논변품질이 뛰어나고, 신문뉴스를 열독하고, 정치참여의지가 높으며, 인터넷 정치토론 공간에서 열심히 읽고 또한 쓰는 시민임이 확인되었다. 마지막으로, 이들은 동료 토론자들로부터 더 많은 찬

An assembly model consists of component models and their relations. Conventional CAD systems support 3 dimensional visualization of component models in flat 2D screen. Here, assembly simulation of the assembly model is proposed where the components are displayed and manipulated in 3D environment in real time using the virtual reality interface and the designer can visualize and manipulate the computer based assembly model naturally like a physical mock up. A real time manipulation of component m

Purpose: The purpose of the study was to identify factors affecting the innovative behavior of general hospital professional staff. Methods: In the final analysis, the study focuses on the 442 structured questionnaires received from the professional staff (doctors, nurses, medical technicians, and administrative staff) of H Hospital, a public medical foundation. Data were collected from August 1 to 31, 2014. The SPSS/WIN 19.0 program was used for data analysis which included t-test, ANOVA, Schef

Abstract This study examined how users’ self-views (i.e., identity coherence, identity confusion, self-esteem) and their self-presentation through avatars (i.e., the number of avatars used, self-avatar dissimilarity, the frequency of and the expenditure on avatar customization) in the metaverse mutually influence each other, based on a three-wave panel survey of Zepeto users in South Korea (N = 640). Dynamic fixed-effects models yielded no significant effects of self-views on avatar-based self-p

This study examined the psychological mechanisms underlying the persuasive effects of moral reframing—matching message content to recipients’ core moral foundations—by focusing on processing fluency, message processing depth, and self-affirmation as mediators. An online experiment conducted in South Korea demonstrated that, across two policy issues, moral reframing promoted processing fluency and self-affirmation, thereby enhancing the perceived persuasiveness of policy advocacy messages. Furthe

What makes health news articles attractable and viral? Why do some articles diffuse widely by prompting audience selections (attractability) and subsequent social retransmissions (virality), while others do not? Identifying what drives social epidemics of health news coverage is crucial to our understanding of its impact on the public, especially in the emerging media environment where news consumption has become increasingly selective and social. This dissertation examines how message features
