Dengue infection is becoming a serious global health threat. Public awareness is a pre-requisite for the successful implementation of dengue prevention programs. The main purpose of this study was to investigate dengue-related information needs and seeking behavior of the general public in Singapore. Some areas covered by this study were: importance of dengue-related information needs, preferred channels for seeking information, and respondents' perceptions of using dengue-related information. A questionnaire was used for data collection and 152 individuals participated in this study. Data analysis showed that the most sought after information concerned: dengue-related medicines, primary symptoms of dengue infection, and different possible treatments. The popular channels for seeking information were: websites of hospitals and other health agencies, the social media, television, and newspapers. Medical staff, such as doctors and nurses, were trusted for providing accurate information. Although credibility of social media was considered low, respondents were using it due to its easy accessibility. The findings of this study will be useful to government health departments in Singapore as well as in other countries suffering from dengue, hospitals, and public welfare agencies involved in public health awareness campaigns.

This study measured the effects of fake news and propaganda on managing information on COVID-19 among the Nigerian citizenry. This study examined sources of information on COVID-19 available to the people, evaluated reasons behind spreading fake news, examined how fake news has affected the spread of COVID-19 pandemic in Nigeria, established the consequences of fake news on managing COVID-19 pandemic and as well identified ways to contain fake news at a time like this in Nigeria.It is a survey with a sample size of 375 participants selected using simple random technique. Instrument of data gathering was questionnaire widely distributed in the six geo-political zones of Nigeria using Survey monkey. Data was analysed using frequencies, counts and percentages, tables and charts. Findings revealed that people rely more on radio, television, and social media for information on COVID-19. Fake news is spread by people mostly for political reasons and intention to cause panic. In Nigeria, fake news has led to disbelief of the existence of the virus thereby leading to violation of precautionary measures among the citizenry and lack of trust in the government. Concerted effort on the part of the government is required to give public enlightenment on the danger of fake news. Also, directorate of anti-fake news should be established to censor and reprimand sources of fake news. People should always check source of information to confirm its credibility and be weary of sharing unconfirmed information especially on the social media.

This study analyzed the impact of YouTube creator characteristics and channel access factors on the intention to continue watching content, noting that the development of the digital media environment has diversified media audiences' content preferences and access routes. Specifically, we analyzed the effects of YouTube creator trustworthiness, attractiveness, familiarity, and social influence, as well as the effects of recommendation services on perceived usefulness, perceived ease, and perceived enjoyment. The study found that creator credibility and recommendation service had a positive impact on the perceived usefulness of content, while intimacy and charm were important factors in increasing the easy of use and playfulness of content. These perceived usefulness, ease, and playfulness also had a strong positive impact on users' intention to continue watching the channel. This suggests that trust and intimate relationships with creators and appropriate content recommendations play an important role in increasing user satisfaction and channel persistence. The significance of this study's analysis of creator and channel access factors based on the extended technology acceptance model is that it shows the potential for extending and applying the existing technology acceptance model to the digital content environment.

This study provides a national examination on youths' 'understanding' of irradiated food. The 1,200 subjects of the survey were randomly sampled from male and female students throughout the nation, between grades five and eleven. The survey was conducted toward these samples in November 2000. The number of respondents with exposure to irradiated food was so small, amounting to only 4.0 percent of the whole sample. The core concept used in this study is 'impression'. An impression is information about a specific subject, which carries significance to an individual. The results show that the higher the grade was, the more value the contents of impression contained. Furthermore, impressions concerning atomic or nuclear energy, and radioactivity increased greatly among students in middle school and above. Providing information of effects and advantages of irradiated food was focused to increase positive impressions and decrease the negative ones more greatly than providing simple factual information. Youths showed less value-centered impressions of irradiated food and more impressions centered on fragmented facts than adults. Respondents previously exposed irradiated food were shown to acquire the most of their information from the television and newspaper media. Among six information sources presented in the survey, youths pointed out 'science and technology research institutes' as the most credible. International organizations and environmental/ consumer organizations were evaluated as having relatively high credibility. Providing simple factual information of irradiated food did not seem to bring about any difference to the intention of purchasing irradiated food. On the other hand, respondents provided with effects-included information showed an increase in such intention. Our research results of the youth show a notable difference with that of the adults. Thus, programs and strategies to enhance youths' understanding should differ from those concerning adults.

Nowadays, fake news from newspapers and social media is a serious issue in news credibility. Some of machine learning methods (such as LSTM, logistic regression, and Transformer) has been applied for fact checking. In this paper, we present Transformer-based fact checking model which improves computational efficiency. Locality Sensitive Hashing (LSH) is employed to efficiently compute attention value so that it can reduce the computation time. With LSH, model can group semantically similar words, and compute attention value within the group. The performance of proposed model is 75% for accuracy, 42.9% and 75% for Fl micro score and F1 macro score, respectively.

There emerges a growing concern about South Korea's intellectual dependence on U.S. financial news media. However, those media's inherent relationship with national economic and financial interests has been poorly addressed. This paper thus attempts to identify such a strategic partnership between media and the government by analysing news coverages over four critical arena interwoven with U.S. dollar based financial system. For this purpose, total 152 news articles about Asia crisis, Asian Monetary Fund, Malaysia currency crisis and the new international financial architecture have been examined in terms of frame, attitude, cue-givers and discursive strategies. Research results indicate that not only have the media actively deferred to government leadership bur they have also acted as public diplomats in way of not hampering journalistic credibility. Hence, it is claimed that Korean society needs to formulate a model of media's strategic partnership with government at least in foreign policy arena, as well as to launch discursive strategies against nation-bound global news media.

Modeling and simulation of mechanical response of infrastructure object, solids and structures, relies on the use of computational models to foretell the state of a physical system under conditions for which such computational model has not been validated. Verification and Validation (V&V) procedures are the primary means of assessing accuracy, building confidence and credibility in modeling and computational simulations of behavior of those infrastructure objects. Validation is the process of determining a degree to which a model is an accurate representation of the real world from the perspective of the intended uses of the model. It is mainly a physics issue and provides evidence that the correct model is solved (Oberkampf et al. 2002). Our primary interest is in modeling and simulating behavior of porous particulate media that is fully saturated with pore fluid, including cyclic mobility and liquefaction. Fully saturated soils undergoing dynamic shaking fall in this category. Verification modeling and simulation of fully saturated porous soils is addressed in more detail by (Tasiopoulou et al. 2014), and in this paper we address validation. A set of centrifuge experiments is used for this purpose. Discussion is provided assessing the effects of scaling laws on centrifuge experiments and their influence on the validation. Available validation test are reviewed in view of first and second order phenomena and their importance to validation. For example, dynamics behavior of the system, following the dynamic time, and dissipation of the pore fluid pressures, following diffusion time, are not happening in the same time scale and those discrepancies are discussed. Laboratory tests, performed on soil that is used in centrifuge experiments, were used to calibrate material models that are then used in a validation process. Number of physical and numerical examples are used for validation and to illustrate presented discussion. In particular, it is shown that for the most part, numerical prediction of behavior, using laboratory test data to calibrate soil material model, prior to centrifuge experiments, can be validated using scaled tests. There are, of course, discrepancies, sources of which are analyzed and discussed.

On a huge space of information called the Internet, users can use a smart mobile web to get information on various intellectual fields and can access to various Medias such as personal blogs and social networking sites (SNS). This is why a vast amount of information on the web has been effectively managed and researched nowadays through a technology named Semantic Web. However, it still needs for an improvement for studies on searching for intellectual information, though it is enhanced to integrate variously spread information and search for intellectual information user-oriented. Thus, this study aims to research on searching information and knowledge spread around a knowledge-filled information space, which can improve credibility according to user-oriented logic.

Purpose Recently, Internet personal broadcasting has been widely spreaded as a new media type by replacing traditional legacy media such as TV. Considering this phenomenon, this study aims to explore the effect of Aristoteles' persuasion factors on Internet personal broadcasting from a rhetorical view. The reason why users watch the Internet personal broadcasting is that they are persuaded by creator's expertness, empathy, or content usefulness. These factors can be regarded as persuasion factors. Therefore, with Aristoteles' rhetorical persuasion factors composed of ethos, pathos, and logos, this paper tries to investigate how persuasion factors affect user's emotional\ attachment and voluntary donation intention. Design/methodology/approach This paper proposes a model of the relationships among three rhetorical factors, user's emotional attachment, and donation intention. Specifically, ethos is regarded as creator's expertness and trustworthiness, and pathos refers to creator's empathy and social interaction. Last, logos refers to content usefulness and credibility. For testing a hypothetical research model, this study collected 468 surveys and empirically tested hypotheses using a structural equation model. Findings This study investigated how rhetorical factors (ethos, pathos, and logos) and emotional attachment further influence user's donation intention. The findings suggest that rhetorical factors of ethos and pathos enhances emotional attachment, followed by donation intention. Contrary to an expectation, however, logos was not significantly related to emotional attachment. Creators of Internet personal media and MCN providers should focus on the different effects of rhetorical factors and pay attention to the role of emotional attachment to encourage user donation.

This article reviews a few academic discussions in our geological society. The author presents his opinion on the discussions regarding the ages of the Okcheon Group, Myogog Formation, and hominid footprints of the Jeju Island, as well as on the inaccurate reportage in mass media. The academia advances via healthy debates and discussions. The arguments for and against Darwin's "Origin of Species" and scientific debates regarding Wegener's "Continental Drift Hypothesis" are well known. In academic debates or discussions, authority should not be involved in any form. Academic research should be conducted based on scientific principles and evidence-free of personal preferences or other nonacademic factors. Opponents should challenge with scientific approaches, suggesting alternatives based on science. Opposition without scientific basis is not productive in conducting academic research in search of scientific truth. Often, the news media delivers inaccurate information to the public-intentionally or unintentionally. There must be a mechanism to immediately identify and rectify inaccurate, false, or fake information for the benefit of the public and the credibility of the news media.
