YouTube Videos Related to the Fukushima Nuclear Disaster: Content Analysis

Background YouTube (Alphabet Incorporated) has become the most popular video-sharing platform in the world. The Fukushima Daiichi Nuclear Power Plant (FDNPP) disaster resulted in public anxiety toward nuclear power and radiation worldwide. YouTube is an important source of information about the FDNPP disaster for the world. Objective This study's objectives were to examine the characteristics of YouTube videos related to the FDNPP disaster, analyze the content and comments of videos with a quantitative method, and determine which features contribute to making a video popular with audiences. This study is the first to examine FDNPP disaster–related videos on YouTube. Methods We searched for the term “Fukushima nuclear disaster” on YouTube on November 2, 2019. The first 60 eligible videos in the relevance, upload date, view count, and rating categories were recorded. Videos that were irrelevant, were non-English, had inappropriate words, were machine synthesized, and were <3 minutes long were excluded. In total, 111 videos met the inclusion criteria. Parameters of the videos, including the number of subscribers, length, the number of days since the video was uploaded, region, video popularity (views, views/day, likes, likes/day, dislikes, dislikes/day, comments, comments/day), the tone of the videos, the top ten comments, affiliation, whether Japanese people participated in the video, whether the video recorder visited Fukushima, whether the video contained theoretical knowledge, and whether the video contained information about the recent situation in Fukushima, were recorded. By using criteria for content and technical design, two evaluators scored videos and grouped them into the useful (score: 11-14), slightly useful (score: 6-10), and useless (score: 0-5) video categories. Results Of the 111 videos, 43 (38.7%) videos were useful, 43 (38.7%) were slightly useful, and 25 (22.5%) were useless. Useful videos had good visual and aural effects, provided vivid information on the Fukushima disaster, and had a mean score of 12 (SD 0.9). Useful videos had more views per day (P<.001), likes per day (P<.001), and comments per day (P=.02) than useless and slightly useful videos. The popularity of videos had a significant correlation with clear sounds (likes/day: P=.001; comments/day: P=.02), vivid information (likes/day: P<.001; comments/day: P=.007), understanding content (likes/day: P=.001; comments/day: P=.04). There was no significant difference in likes per day (P=.72) and comments per day (P=.11) between negative and neutral- and mixed-tone videos. Videos about the recent situation in Fukushima had more likes and comments per day. Video recorders who personally visited Fukushima Prefecture had more subscribers and received more views and likes. Conclusions The possible features that made videos popular to the public included video quality, videos made in Fukushima, and information on the recent situation in Fukushima. During risk communication on new forms of media, health institutes should increase publicity and be more approachable to resonate with international audiences.

BACKGROUND YouTube is a popular American video-sharing platform that has been accessible to the public since 2005. Previous studies have shown that YouTube is potentially beneficial to medical education, but the quality of videos still need to be determined. OBJECTIVE The goal of this study is to understand the quality of the YouTube videos by evaluating the characteristics of physicians and the total number of views on videos regarding fibromyalgia. METHODS The term “fibromyalgia” was searched on the YouTube search engine by relevance, the default setting. Information from the first 100 videos were analyzed. A search was performed on Scopus to determine the h-index and fibromyalgia-related publication for any physician who was featured in the videos. RESULTS Of the top 100 videos, there were 64 academic videos, 18 vlogs, 5 interview videos, and 13 miscellaneous videos. Out of the 64 academic videos, 30 physicians, 7 Doctors of Philosophy (Ph.D.), 5 physical therapists, and 5 chiropractors were identified. The majority physicians have an adequate academic affiliation such as h-index and academic publications. CONCLUSIONS Residents and medical students will encounter a large number of academic videos on fibromyalgia on YouTube. This study suggests that many videos were posted for academic purposes and that the quality of the videos can be ensured to some degree. However, developing a better systemic evaluation of the quality of YouTube content is still necessary.

Fukushima Nuclear Disaster

The Fukushima nuclear disaster has raised the importance on the reliability and risk research of the spent fuel pool (SFP), including the risk of internal events, fire, external hazards and so on. From a safety point of view, the low decay heat of the spent fuel assemblies and large water inventory in the SFP has made the accident progress goes very slow, but a large number of fuel assemblies are stored inside the spent fuel pool and without containment above the SFP building, it still has an unignored risk to the safety of the nuclear power plant. In this paper, a standardized approach for performing a holistic and comprehensive evaluation approach of the SFP risk based on the probabilistic safety analysis (PSA) method has been developed, including the Level 1 SFP PSA and Level 2 SFP PSA and external hazard PSA. The research scope of SFP PSA covers internal events, internal flooding, internal fires, external hazards and new risk source-fuel route risk is also included. The research will provide the risk insight of Spent Fuel Pool operation, and can help to make recommendation for the prevention and mitigation of SFP accidents which will be applicable for the SFP configuration risk management.

Fukushima Nuclear Disaster

What happens when expertise is forced to face disasters of unprecedented scales? How is knowledge produced in critical moments when every action and decision is a matter of life and death? And how are local social networks mobilized to cope with unforeseen crisis? This paper addresses these questions by examining the emergence of disaster medicine expertise in the aftermath of Fukushima nuclear disaster that struck Japan in 2011. Studies on Fukushima’s impact have to date revolved around the suffering of Tōhoku citizens and the development of Japan’s nuclear energy industry. Acknowledging the gravity of such work, this paper offers an alternative, but equally crucial angle on the disaster: that of the medical caregiving and public health system built in response to radiation hazards resulting from the triple meltdowns at Fukushima Daiichi nuclear power station. Through detailed interviews conducted with eight medical practitioners in Fukushima Prefecture, this paper analyses the significance and impact of Japan’s most recent radiation disaster on its public health infrastructure. To describe the contingent nature of radiation disaster medicine developed in response to radiation risk in Fukushima, we draw on Jasanoff’s characterization of scientific knowledge as ‘serviceable truths’ with regards to public policy and the law, suggesting that expertise in relation to disasters is usefully understood in analogous terms.

Fukushima Nuclear Disaster

AbstractOfficial investigations that followed the Fukushima Nuclear Disaster revealed that it could have been prevented by reasonable safety measures. Investigators concluded that close relationships between government officials and industry executives led to very weak regulatory oversight and the failure to address the risk of violent earthquakes and tsunami such as those that struck the Fukushima Nuclear Power Station on March 11, 2011. News reporters conducted their own investigations in the months following the disaster. Japan’s information disclosure law provided an invaluable tool that enabled them to obtain government records related to regulation of Japan’s nuclear power plants. This article describes some of the stories they produced. Appearing on the front pages of newspapers with daily circulations in the millions, this work provided an authoritative inside view of the failed regulatory process to the Japanese people. The work of the investigative bodies and the news media drove the demand for change that led to disbanding of the regulatory agencies that failed and their replacement by an entirely new regulatory body. This article highlights the importance of “right to know” laws such as Japan’s information disclosure law in creating the opportunity for news reporters and others to demand the release of otherwise confidential government records that can enlighten everyone on matters of great public interest.

Fukushima Nuclear Disaster

AbstractLiterature expects that an attitude toward nuclear power is in direct proportion to the perceived risk of accidents at an operational nuclear power plant; that is, the oppositional attitude is based on the view that nuclear technology is risky and support for nuclear power is related to a perceived low risk and/or potential benefit. However, it is misleading to assume that individuals’ risk perception alone can linearly explain their position after such an accident. The association between risk perception and attitude toward nuclear power varies significantly according to country but, until now, has been largely unexamined. This article takes into consideration the effects of structural factors on that relationship by examining public attitudes toward nuclear energy after the Fukushima nuclear accident in March 2011 and reveals that the need for the efficient production of electricity (i.e., nuclear energy) outweighs concern for the potential danger of a nuclear incident. Although a country's dependence on nuclear power for the production of electricity engenders anti-nuclear attitudes, it is evident that a level of economic development largely alleviates any negativity relative to that energy source.

Nuclear Disaster

After the Fukushima Daiichi nuclear disaster, the public acceptance of nuclear power has dwindled to historical low. Governments were forced to cancel and postpone new projects or even shut down reactors in operation due to an increased anti-nuclear sentiment. This paper aims to provide an international perspective of how various factors can affect public opinion of nuclear power. In this paper, we rebut the previous-held argument that nuclear education is conducive to the public support of nuclear power. It is found that the relationship between educational efforts and public support is captured by a downward-sloping line. The paper then assesses the effect on the public acceptance of demographics, socioeconomic status, political environment and risk orientation using correlation coefficients table. The largest public concern comes from the insecurity of nuclear power plants and radioactive materials. The health of an economy also plays a major role in determining people’s attitude toward building new nuclear power plants. The paper also suggests some solutions for each category of countries based on the research analysis.

Fukushima Nuclear Disaster

Many thought that the 11 March 2011 Fukushima nuclear disaster in Japan might be the end of the “global nuclear renaissance.” In Europe, mass media after Fukushima increasingly presented negative framing of nuclear energy and highlighted declining support for the nuclear industry. In the United States, however, nuclear production and public support for the industry remained steady. This article analyzes US media documents to understand the construction of public discourse on nuclear power in the wake of the Fukushima disaster. Through a content analysis of US newspapers, it demonstrates that post-Fukushima media framed the crisis in a way that privileged expert knowledge and opinion, while delegitimizing non-expert engagement with nuclear energy issues. A comparison between national newspapers and newspapers located in two regions with controversial nuclear plants and active anti-nuclear citizens’ movements additionally demonstrates the power and reach of the identified framework across the spectrum of views on nuclear power.

Leadership style is not a novel concept and has been discussed widely all over the world. With the acceleration of globalization, organizations have to adapt to new paradigms or approaches of leadership. Therefore, it is important to understand leadership preference among individuals to ensure their willingness to perform their job. Specifically, this study was conducted to identify the relationship between gender, age, education level and working experience and leadership preference. This study intends to understand the leadership preference among Sabah communities which involve three major ethnic groups in Sabah namely Malay-Brunei, Bajau and Kadazan-Dusun. The sample of this research was selected based on purposive convenient sampling whereby all respondents are located in Kota Kinabalu. A questionnaire was administered for data collection with a sample of two hundred and nineteen employees from both the public and the private sectors. The data was analyzed using one way ANOVA and the results showed that the three major ethnic groups in Sabah appear to have similar leadership preference. In addition, no significant difference was found between leadership preferences and the demographic variables.
