Public psychological reaction to food safety emergencies is influenced by various factors like the destructive force of events, the influence of rumors, government intervention and public risk response ability, among which the most direct influence to public psychology is disaster information dissemination. This paper investigate the influences that panic growth rate, white noise rumor and government intervention have on public psychology amidst food safety emergencies, and propose the public psychology regulation system to cope with food safety emergencies. The goal of our research is: revealing the mutual inhibition mechanism between mass rationality and mass panic in food safety events. Our research results indicate that with the changes of mass panic growth rate, the public psychology differentiates into two steady states (mass panic and public numbness) and one unsteady state (mass rationality state). Meanwhile, mass panic and public numbness leap to change at the saddle node bifurcation points, and there exists a lagging effect.

Precise Assessment

Chlorination has been believed to be the best sterilization method in water supply engineering for many years. However, the recent carcinogenic problem of trihalomethanes (THM) formed from organic compounds by chlorination requires us to assess the public health risk of THM. The author tried an assessment of a suitable chlorination technique considering both the effects of THM and viruses on human health, using Lake Biwa as a representative example of a water resource in Japan. Statistical handling of data was revealed to be important because of the statistical nature of the data. In other words, since both concentrations are very low in tap water, we need to quantify both the effects and concentrations with probabilities. In the first part of this paper, a statistical procedure and numerical results of the assessment of virus and THM risks are shown. In the second part some results of accuracies in virus experiments are briefly shown. These experiments concerning statistical problems are particularly important for more precise assessment of the public risk of viruses in tap water.

Food Safety And Quality

Currently, we assist the emergence of sensors and low-cost information and communication technologies applied to food products, in order to improve food safety and quality along the food chain. Thus, it is relevant to implement predictive mathematical modeling tools in order to predict changes in the food quality and allow decision-making for expiration dates. To perform that, the Baranyi and Roberts model and the online tool Combined Database for Predictive Microbiology (Combase) were used to determine the factors that define the growth of different bacteria. These factors applied to the equation that determines the maximum specific growth rate establish a relation between the bacterial growth and the intrinsic and extrinsic factors that define the bacteria environment. These models may be programmed in low-cost wireless biochemical sensor devices applied to packaging and food supply chains to promote food safety and quality through real time traceability.

Network Public Opinion

The real-time and dissemination characteristics of network information make net-mediated public opinion become more and more important food safety early warning resources, but the data of petabyte (PB) scale growth also bring great difficulties to the research and judgment of network public opinion, especially how to extract the event role of network public opinion from these data and analyze the sentiment tendency of public opinion comment. First, this article takes the public opinion of food safety network as the research point, and a BLSTM-CRF model for automatically marking the role of event is proposed by combining BLSTM and conditional random field organically. Second, the Attention mechanism based on vocabulary in the field of food safety is introduced, the distance-related sequence semantic features are extracted by BLSTM, and the emotional classification of sequence semantic features is realized by using CNN. A kind of Att-BLSTM-CNN model for the analysis of public opinion and emotional tendency in the field of food safety is proposed. Finally, based on the time series, this article combines the role extraction of food safety events and the analysis of emotional tendency and constructs a net-mediated public opinion early warning model in the field of food safety according to the heat of the event and the emotional intensity of the public to food safety public opinion events.

The Impact

We experimentally test whether expert organizations on social media can correct misperceptions of the scientific consensus on the safety of genetically modified (GM) food for human consumption, as well as what role social media cues, in the form of “likes,” play in that process. We find expert organizations highlighting scientific consensus on GM food safety reduces consensus misperceptions among the public, leading to lower GM misperceptions and boosting related consumption behaviors in line with the gateway belief model. Expert organizations’ credibility may increase as a result of correction, but popularity cues do not seem to affect misperceptions or credibility.

After the occurrence of public health emergencies, due to the uncertainty of the evolution of events and the asymmetry of pandemic information, the public’s risk perception will fluctuate dramatically. Excessive risk perception often causes the public to overreact to emergencies, resulting in irrational behaviors, which have a negative impact on economic development and social order. However, low-risk perception will reduce individual awareness of prevention and control, which is not conducive to the implementation of government pandemic prevention and control measures. Therefore, it is of great significance to accurately evaluate public risk perception for improving government risk management. This paper took the evolution of public risk perception based on the COVID-19 region as the research object. First, we analyze the characteristics of infectious diseases in the evolution of public risk perception of public health emergencies. Second, we analyze the characteristics of risk perception transmission in social networks. Third, we establish the dynamic model of public risk perception evolution based on SEIR, and the evolution mechanism of the public risk perception network is revealed through simulation experiments. Finally, we provide policy suggestions for government departments to deal with public health emergencies based on the conclusions of this study.

In Indonesia, currently they are still fighting the Corona / Covid 19 Virus, as well as in other countries. The number of cases affected by patients continues to grow. In several reports reported recovery, but not a few who died. Information dissemination aims to change people's attitudes, beliefs and behavior through providing information and raising awareness that a problem that arises can be overcome, especially in terms of preventing the transmission of Covid 19 through the selection and use of good and correct masks.Providing correct knowledge to the public can be done in various ways, one of which is by directly socializing the knowledge that will be given. This community service activity is carried out by extension methods, distributing information brochures, distributing masks and directly teaching the community how to use masks and choosing the right and good masks.After health education was carried out, the community understood and wanted to choose masks and use masks correctly. The public also understands the importance of taking preventive measures so as not to be infected or exposed to the Covid 19 virus.Health education activities should be carried out routinely by health workers in order to improve public health by changing people's life habits to be clean and healthy ones

This article is based on the results of research which the aim is to find out how is mapping of the education information dissemination network in the community of Cintaratu village, Pangandaran district. The reason for choosing the topic was that Padjadjaran University (Unpad) campus is in the village and it is assumed that the presence of the university in the village could improve the quality of education of its people. To confirm this assumption, it is necessary to map the education sector information network. We use qualitative methods which approach is a descriptive study, the researchers conducted a mapping of educational information dissemination. The main informants of this study are the community and village officials. Data were collected through in-depth interviews, passive participatory observation, and literature studies. The finding of the research are as follows, 1) the initial mapping of educational information dissemination to the community was carried out through direct communication, namely through two major activities - recitation and celebration; 2) recitation and celebration are two activities that are susceptible to physical noise-causing information related to education not conveyed properly to the public. Effective communication does not occur in these two activities.

Safety Rules

This chapter explores the evolution of food trucks and food safety regulations for these vehicles in the Los Angeles region between WW2 and the present. It shows how food trucks have reacted to and influenced the region’s industrialization and deindustrialization, and how food trucks became more informal and public as immigration made Los Angeles a majority non-white metropolis. In considering how food safety changed as operators began cooking on board trucks, the chapter examines how safety rules can both protect the public and reflect social norms of legitimacy around identity and public space.
