This study also examines whether superordinate identification intensifies support for people-to-people exchanges and unification using an experiment. South Koreans’ increased superordinate identification with North Koreans leads to greater humanization of the latter as well as less negative feelings toward them but does not affect support for unification. This suggests that extended contact is enough to generate superordinate identification with the outgroup but not enough to affect support for government policies.

We compared the prognosis of Korean patients with recurrent gastric cancer according to the presence or absence of cancer‐related symptoms at the time of recurrence detection.MethodsWe retrospectively reviewed the medical records of 305 Korean patients who experienced recurrence after curative resection of primary gastric cancer between March 2002 and February 2017 at Yonsei Cancer Center, Yonsei University College of Medicine, Seoul, Republic of Korea.ResultsThe median follow‐up duration was 169.8 months (1–267.2), and the median age at first recurrence was 58.1 years (23.4–81.9). Among 305 patients with recurrence, 97 of 231 (42.0%) patients with early recurrence (≤5 years after curative surgical resection) and 47 of 74 (63.5%) patients with late recurrence (>5 years after curative surgical resection) had cancer‐related symptoms at recurrence (p ...

We determine the elements of framing strategies and narrative styles in facilitating public attention, positive and negative responses, and engagement in news content. We used the YouTube application programming interface to collect data from VideoMug, Korea’s most popular YouTube channel, run by the Seoul Broadcasting System. We examined 23,774 replies commenting on North Korea-related video clips from July 1, 2018, to May 17, 2019. The findings show that entertainment and human interest frames were effective in drawing public attention to news coverage about North Korea. Using humor and colloquial language facilitated public attention (both positive and negative) and public engagement. Over half (59.55%) of the comments generated positive emotions; less than one-third generated negative emotions (31.41%);...

First, the study investigated the response strategies Samsung used on Facebook through the lens of situational crisis communication theory (SCCT). Next, we applied a webometric network analysis and exponential random graph models (ERGM) to analyze the relationship between the crisis response strategies and the dynamics of electronic word of mouth (eWOM) behaviors. Then, we performed topic modeling and semantic network analysis to examine the public perceptions of and responses to Samsung’s crisis communication strategies based on public comments. Samsung used silence, information, and rectification strategies. More participants and comments were generated and stronger ties were found in the eWOM networks for matched responses than for silence. Public responses and perceptions t...

This study investigates the effects of framing of celebrities’ messages (emotional framing and framing of celebrity involvement) on public attitudes and behaviors to address climate change. A sequential mediation process is examined with structural equation modeling. In addition, this study assesses the role of parasocial relationship (PSR) with celebrities as predictors and moderators of the impact of framing of celebrity involvement. The results indicate that fear appeals were more effective than hope appeals in driving participation in activism, but emotional framing did not affect any other variables. Framing of celebrity involvement appeals using first-person pronouns led to more positive attitudes, but had no effect on behaviors. In addition, PSR was a strong positive predictor of attitudes and behaviors.

The role of social media amid the current coronavirus disease (COVID-19) pandemic has often been criticized, but little systematic research has been conducted on this issue. Social media functions as a convenient source of information in pandemic situations. OBJECTIVE Few infodemiology studies have applied network analysis in conjunction with content analysis. This study investigates information transmission networks and news-sharing behaviors regarding COVID-19 on Twitter in Korea. The real time aggregation of social media data can serve as a starting point for designing strategic messages for health campaigns and establishing an effective communication system during this outbreak. METHODS Korean COVID-19-related Twitter data were collected on February 29, 2020. Our f...

The study compared the networking power of public diplomacy organizations based on social media use, engagement with the public, interaction patterns among the public, and public perceptions and attitudes toward organizations. This was accomplished through a three-step method employing social network analysis and topic modeling. The network analysis found that the Korean public diplomacy organization generated a larger, more loosely connected, and decentralized comment network than the Japanese organization, which presented a "small-world" connectivity pattern with highly interconnected actors. The findings also suggest that, compared to the Japanese organization, the Korean organization was successful in not only enhancing its soft power through social media but also building international networks among the foreign public.

This article identifies the most visible politicians on Cyworld in terms of comments posted on their profiles between April 1, 2008 and June 14, 2009 and examines the text and sentiments reflected in those profiles. A content analysis combining semantic network analysis and sentiment analysis illustrates the meaning and collective sentiment of the comments. The results suggest that progressivism dominated political discourse and that the members of the ruling party received more negative comments than those of the opposition party. Furthermore, group-oriented terms indicated the existence of collectivism, which is representative of Eastern culture. The results suggest a significant relationship among gender, comment types, and SNS activities.
