Background: From 2018 to 2020, the Expert Study on Public Understanding after the Fukushima Daiichi Nuclear Power Plant Accident (the Expert Study Group) identified and analyzed activities designed to promote public understanding of science and radiation since the Fukushima accident, and held discussions on how to achieve public understanding in the situation where public confidence has been lost, and how experts should prepare for dealing with the public. This panel session was held at the 53^rd meeting of the Japan Health Physics Society on June 30, 2020. Materials and Methods: First, three subgroup (SG) leaders reported their research methods and results. Then, two designated speakers, who participated as observers of the Expert Study Group, commented on the activities. Next, the five speakers held a panel discussion. Finally, the rapporteur summarized. Results and Discussion: SG leaders presented reports from researchers and practitioners in health physics and environmental risks who provided information after the Fukushima accident. During the discussion, experts in sociology and ethics discussed the issues, focusing on the overall goals of the three groups, local (personal) and mass communication, and ethical values. Many of the activities instituted by the experts after the accident were aimed at public understanding of science (that is, to provide knowledge to residents), but by taking into account interactions with residents and their ethical norms, the experts shifted to supporting the residents' decision-making through public engagement. The need to consider both content and channels is well known in the field of health communication, and overlaps with the above discussion. Conclusion: How to implement and promote the public engagement in society was discussed in both the floor and designated discussions. Cooperation between local communities and organizations that have already gained trust is also necessary in order to develop relationships with local residents in normal times, to establish an information transmission system, and to make it work effectively.

Background: One of the most prevalent cancers in whole world is skin cancer and its prevalence is growing. The present research sought to estimate relative risk of morbidity and mortality due to skin cancer. Materials and Methods: In this cross-sectional study. The required data were gathered from the registered cancer reports of Cancer Control Office in the Center for Non Communicable Disease of the Iranian Ministry of Health (MOH). The data were extracted at province level in the time span of 2008-10. WINBUGS software was used to analyze the data and to identify high risk regions. ArcGIS10 was utilized to map the distribution of skin cancer and to demonstrate high risk provinces by using classic and fully Bayesian models taking into account spatial correlations of adjacent regions separately for men and women. Results: Relative risk of morbidity for women in Yazd and for men in Kurdistan and relative risk of mortality for women in Bushehr and for men in Kohgiluyeh were found to be the highest. Bayesian model due to regarding adjacent regions correlation, have precise estimation in comparing to classical model. More frequent epidemiological studies to enact skin cancer prevention programs. Conclusions: High risk regions in Iran include central and highland regions. Therefore it is suggested that health decision makers enact public education, using anti UV creams and sunglasses for those parts as a short preventing program.

치과의사는 감염, 알레르기, 시력장애 등 다양한 직업적 위험에 노출되어 있으며, 그 중에서도 비교적 최근 들어 새롭게 제기된 문제가 청력손상이다. 치과 진료실에서 발생하는 소음이 작업장 소음 기준을 초과한다는 조사 결과가 발표된 바 있고, 특히 소아치과 의사는 각종 치과 소음에 더하여 어린이의 울음소리라는 부가적 소음원에도 일상적으로 노출되고 있다. 본 연구는 소아치과 의사에게 영향을 미칠 수 있는 소음 환경에 대해 조사하고, 이에 따른 청력 손상 가능성을 고찰해 볼 목적으로 시행되었다. 휴대용 소음계를 이용하여, 각종 치과용 기구, 어린이의 울음소리, 양자가 동시에 발생할 때의 소음 크기를 각각 측정하고, 소아치과 의사가 소음 환경에 노출되는 시간을 설문을 통해 조사하였다. 이 결과를 National Institute for Safety and Health(NIOSH) 및 Occupational Safety and Health Act (OSHA)의 소음 역치 기준, CRA News letter의 청력 손상을 유발하는 소음 기준과 각각 비교하였다. 그 결과, 소아치과 의사가 노출된 소음 환경은, 강도와 노출 시간을 고려했을 때 허용된 작업장 소음 기준을 초과하며, 어린이의 울음소리는 한 번의 노출로도 영구적 청력 손상을 야기할 수 있는 수준으로 나타났다. 따라서 일반 치과의사와 비교하여 소아치과 의사는 직업적 청력 손상의 위험성이 더 높으며, 이를 최소화하기 위한 적극적인 대책이 필요하다는 결론을 내릴 수 있었다.

Purpose: The continued increase in the world population has triggered an increased demand for food. Cereal grains, flour, and their products constitute the staple diet for most of the world's population. This high demand for food, particularly for cereal-based products, has been exploited for commercial gain through adulteration of food materials. We provide a thorough review of the current developments and limitations of modern, nondestructive analytical techniques used for detection of adulterants in cereals and their products and compare them with conventional methods. Results: Adulterated food poses a serious health risks to humans, animals, and the ecosystem in general. Over the last few decades, the adulteration industry has developed fraudulent practices that often outsmart conventional methods of detection and quality control. Therefore, technological advancements to aid in detection and measurement of adulterants in food products and to ensure food quality and safety are critically important to consumers worldwide. Conclusion: There is a continuous demand for development of nondestructive technology to improve the accuracy and efficiency of detection, measurement, and qualification of adulterants in cereals and other food materials.

Point-of-care photography and photo sharing optimize patient outcomes and facilitate remote consultation imperative for resident surgeons. This literature review and external pilot survey study highlight the risks associated with current practices concerning patient privacy and biometric security. In a survey of 30 plastic surgeon residents and attendings, we found that the majority took photos of patients with their iPhones and shared them with colleagues via Apple iMessage. These findings corroborate previous reports and highlight a lack of physician user acceptance of secure photo-sharing platforms. Finally, we frame a successful example from the literature in the context of a postulated framework for institutional change. Prioritizing the privacy and safety of patients requires a strategic approach that preserves the ease and frequency of use of current practices.

Purpose - The purpose of this study is to determine consumers' awareness of hygiene and the perceived risks in the service areas of coffee shops and diners, or simply coffee shops. Research design, data, and methodology - A literature review was conducted on related publications, essays, and periodicals to find correlations among the variables. We developed a research model and hypothesis, and conducted empirical research for statistical data analysis. Results - The results satisfied adequacy standards, with GFI=0.926, AGFI=0.901, RMR=0.020, NFI=0.941, X²=403.197, and p-value=0.120. The results also displayed satisfied adequacy standards for the moderating effects of shop types, with GFI=0.998 (≥0.9 desirable), AGFI=0.998 (≥0.9 desirable), RMR=0.004 (≤0.05 desirable), NFI=0.999 (≥0.9 desirable), X²=1.572, and p-value=0.814 (≥0.05 desirable). Conclusions - A higher consumer hygienic awareness results in a better brand image. Moreover, greater perceived risk results in a worse brand image. Perceived risk is a vital determinant of brand image and it deeply influences customers' decisions to visit. Therefore, perceived risk is a vital determinant of forming a brand image and must be incorporated when devising strategies.

Nuclear power plant site selection is a complex process and its successful completion is a critical milestone in the NPP development cycle. Proper siting of NPP will ensure public health and safety, environmental conservation, reduced project failure risks and a smooth NPP development process among other benefits. The objective of this paper is to demonstrate the application of systems engineering to the problem of NPP siting in Kenya. The siting process demonstrated in this paper includes stakeholder need analysis where stakeholders are identified and their needs concerning NPP site are elicited and converted into system functional requirements. A value model is then developed and potential sites iteratively subjected to three types of criteria i.e. exclusionary criteria, avoidance criteria and suitability criteria. This process is used to identify the candidate sites. An additive value model; multiple objectives Decision Analysis (MODA) is then used to calculate candidate solutions values. The site with the highest solution value score is selected. Sensitivity studies using different criterion weight sets (thereby reflecting different viewpoints) can be conducted to assess their effect on the selection of a preferred site and thereby lend additional credibility to the decision process.

Although animal studies have been used most often for quantitative risk assessment, it is generally recognized that well-conducted epidemiologic studies would provide the best basis for estimating human risk. However, there are several features related to the design and analysis of epidemiologic studies that frequently limit their usefulness for quantitating risks. The lack of accurate information on exposure in epidemiologic studies is perhaps the most frequently cited limitation of these studies for risk assessment. However. other features of epidemiologic study design, such as statistical power, length of follow-up, confounding, and effect modification, may also limit the inferences that can be drawn from these studies. Furthermore, even when the aforementioned limitations are overcome, substantial uncertainty exists concerning the choice of an appropriate statistical (or biologic) model for extrapolation beyond the range of exposures observed in a particular study. This paper focuses on presenting a review and discussion of the methodologic issues involved in using epidemiologic studies for risk assessment. This review concentrates on the use of retrospective, cohort, mortality studies of occupational groups for assessing cancer risk because this is the most common application of epidemiologic data for quantitative risk assessment (QRA). Epidemiologic data should not be viewed as a panacea for the problems inherent in using animal bioassay data for QRA. Rather, information that can be derived from epidemiologic and toxicologic studies complement one another, and both data sources need to be used to provide the best characterization of human risk.
