We proposed a video summarization algorithm based on an ERP (Event Related Potentials)-based topic relevance model, a MMR (Maximal Marginal Relevance), and discriminant analysis to generate a semantically meaningful video skim. We then conducted implicit and explicit evaluations to evaluate our proposed ERP/MMR-based method. The results showed that in the implicit and explicit evaluations, the average scores of the ERP / MMR methods were statistically higher than the average score of the SBD (Shot Boundary Detection) method used as a competitive baseline, respectively. However, there was no statistically significant difference between the average score of ERP/MMR (${\lambda}=0.6$) method and that of ERP/MMR (${\lambda}=1.0$) method in both assessments.

As the voting age has been lowered to 18 from the 21st general election on April 15, 2020, the use of political news, motivation for political interest, and reliability of political media of first-time voters were examined. Accordingly, we analyzed how their political efficacy affects their voting intentions. As a result of the study through the survey of participants, the use of political news by voters was to acquire political information mainly through TV and portals. And the use of traditional media such as radio and newspaper was low. first voters became interested in politics through articles delivered by the media, and it was found that they trusted the political information provided through terrestrial TV reports and debates. This generation also confirmed that if they have higher political efficacy, they show higher willingness to participate in voting. Through this study, in order to increase the political participation of the younger generation who are evaluated as having relatively low interest in politics, the role of the media was reconfirmed as the most important factor.

A smiling face usually has a positive effect on interpersonal relationships by delivering a warm impression. However, the stereotype content model and compensation effect between warmth and competence suggested that warmth perceptions caused by a smiling face could influence competence perceptions negatively. This study examined the negative impact of the advertising endorser's smile on purchase intention in an expensive product category by adopting the self-construal level. The study results showed that consumers with independent-self construal (vs. interdependent self-construal) showed a lower purchase intention when exposed to an ad containing an endorser's smile. In comparison, consumers with interdependent-self construal (vs. independent self-construal) showed a lower purchase intention when exposed to an ad without an endorser's smile. Thus, this study demonstrated a moderating role of self-construal in the relationship between advertising endorser's smile and purchase intention. These findings provide valuable theoretical and practical implications for effective advertising strategies in the expensive product category.

This study analyzes how Princess Deokhye's photos before entering elementary school were exploited in newspapers during the Japanese colonial period by introducing Roland Barthes' semiological methodology for analysis of photography. In the early 1920s, the Japanese imperialists actively exploited Princess Deokhye, who was about to enter elementary school, to propagate their education policy. The Maeil Shinbo cooperated with their policies by publishing photos and articles of Princess Deokhye. In this paper, 2 photos and articles published in Maeilshinbo were analyzed. As a result, it was found that messages were produced that justified Japanese education policy by using various rhetorical techniques of photography and texts complementary to each other, and that the readers were induced to accept them naturally. In conclusion, it was possible to reveal the seriousness of the problem in that these articles were not merely for propaganda of policy, but were to encourage the disappearance of the traditional values of Joseon.

This study aims to identify topics in newspaper articles related to fine particle matter and to investigate the characteristics and time series trend of each topic. Related national newspaper articles during 1990 and 2021 were collected from Bigkinds. A total of 18 topics have been discovered using LDA, and 11 clusters deduced from clustering. Hot topics include related products/residence, overseas cause(China), power plant as a domestic cause, nationwide emergency reduction measures, international cooperation, political issues, current situation & countermeasure in other countries, and consumption patterns. Cold topics include the concentration standard and indoor air quality improvement. These findings would be useful in inferring the political direction and strategies. In particular, the consumer protection policy should be expanded as the related market is growing. It will also be necessary to pursue policies that will promote public safety and health, and that will enhance public consensus and international cooperation.

In this study, we assessed anti-oxidant activity, anti-microbial, inhibition of biofilm formation and inflammatory factors(nitric oxide, interleukin-6, interleukin-8) inhibitory effect of Perillae semen hydrothermal extract(PSW) and three kinds of Perillae semen supercritical fluid extract(PSSs) extracted by controlling temperature with no variation of pressure. Compared with PSW, PSSs had significantly lower minimal inhibitory concentrations(MICs) against Staphylococcus aureus(S. aureus) and the ability of PSSs to inhibit formation of biofilm was also superior. PSSs reduce the production of inflammatory mediator and inflammatory cytokines significantly compared to PSW. We suggest, therefore, Perillae semen supercritical fluid 45℃ extract which showed the best anti-microbial, inhibition of biofilm formation, and inhibition of inflammatory factors production among the supercritical fluid extracts could be used for protecting patients with atopic dermatitis from pruritus and transepidermal water loss as a functional ingredient from nature.

This study compares the perspectives of experts and the public on the 2015 revised curriculum. To do this, research papers and newspaper articles were collected from October 2013 to May 2020. During this period, 1152 research papers and 692 newspaper articles were collected, and semantic network analysis was performed. As a result of the study, the educational expert group showed great interest in the core concept of the development of the revised curriculum focused on the abstract concept, while the public focused on the practical problems and consequences of the revision rather than the development of the revised curriculum itself. These results not only show the gap between the perspectives of the educational expert group and the public but also raise the need for effective communication to bridge the gap.

Purpose: The number of households vulnerable to isolation increases rapidly as social ties decrease, raising concerns about the associated increase in lonely deaths. This study aimed to identify issues related to lonely deaths by analyzing South Korean news articles; and to provide evidence for their use in preventing and managing lonely deaths via community nursing. Methods: This exploratory study analyzed the structure and trends of meaning of lonely deaths by identifying the association between keywords in news articles and lonely deaths. In this study, we searched for all news articles on lonely deaths, covering the period from January 1, 2010, to May 31, 2023. Data preprocessing and purification were conducted, followed by top-keyword extraction, keyword network analysis and topic modeling. The retrieved articles were analyzed using R and Python software. Results: Four main topics were identified: "discovering and responding to lonely death cases", "lonely deaths ending in lonely funerals", "supportive policies to prevent lonely deaths among of older adults", and "local government activities to prevent lonely deaths and support vulnerable populations." Conclusion: Based on these findings, it can be concluded that lonely death is a complex social phenomenon that can be prevented if society shows concern and care. Education related to lonely deaths should be included in nursing curricula for concrete action plans and professional development.

A theoretical model of information overload (Jackson and Farzaneh, 2012) with its three influential components (i.e., time, technology, and social networks) was empirically tested in the context of news consumption behavior considered as a communicative outcome. Using a national sample of South Korean adults (N = 1166), data analyses identified perceived information overload and large/diverse social networks positively associated with active and passive news consumption. Findings may imply the existence of individually varying cognitive threshold (i.e., tipping point), if crossed individuals cannot process information any further. News consumers may keep searching and receiving information to verify factuality of news even when they feel overloaded.

The inauguration of President Lee Myung-bak symbolizes the success of the "Lost 10 Years" election strategy. This study investigated the meaning of the "Lost 10 Years" strategy and compared this strategy to other traditional propaganda strategies. Although the "Lost 10 Years" is a Grand National Party (GNP) election strategy, it also functions as a conservative propaganda strategy by conservative political groups and media. Thus, this study intends to compare the rhetoric of the GNP with conservative media and find any similarities between the two entities in the context of the "Lost 10 Years" propaganda strategies. This study gathered data from various conservative sources such as the GNP homepage and conservative newspapers to uncover common conservative propaganda messages. The results showed that the first-level propaganda strategies are very similar to the second-level traditional Lasswell strategies. This implies that the "Lost 10 Years" strategy benchmarked traditional propaganda strategies and the GNP won the presidential election because the effectiveness of traditional propaganda strategies was culminated with the support of the conservative media. With these research findings, the study discussed the implications of the propaganda strategies used by conservatives and future research prospects about the subject.
