Purpose: This study aims to explore the effects of government's value intervention messages on the prevention and control of infectious disease in the risk communication process in terms of goveremnt policy response to COVID-19 from the mismatch message perspective, and draws the relevant implicaitons. Due to the infeciton spread, some people point out that depression caused by COVID-19 is because of wrong signals of the government and infectious disease prevention and control authorities, namely value intervention messsages. Research design, data and methodology: This study examined the epidcmic situation through message deails regarding the effects of government's mismatch messages on prevention and control of infectious disease and the resulting phenomena. Results: People's lives are under serious threat overall, so the declaration of the end of COVID-19 is almost impossible unlike MERS. Economic downturn due to foreced prevention and control regulaitons of COVID-19, mistruct of social distancing, fatigue on mismatch messages, and moral hazard on the awareness of prevention and control of infectious disease are negative phenomena to risk communiaiton on COVID-19. Conclusions: This study investigated the government authorities' policy sending wrong signals due to mismatching of the reality at this point in time for infectious disease prevention and control from the risk communicaiton perspectrive.

The objective of the study is to empirically investigate the impact of bank capital on the lending behavior of Vietnamese commercial banks from 2007 to 2019. Lending behavior is captured by two dimensions, including the quantity (loan growth) and quality (credit risk) of loans. Instead of investigating loan growth and credit risk separately, we combine these two aspects in our study and further develop the interaction term between capital buffers and credit risk to capture the asymmetric impact. We apply the dynamic model (regressed by the generalized method of moments) and the static models (regressed using the fixed effects, random effects, and the pooled regression approach) to perform regressions. The results show that banks with higher capital ratios tend to expand lending more, while the risk of credit portfolios is controlled at lower levels at these banks. Further analysis reveals that credit risk mitigates some aspects of the relationship between bank capital and loan expansion. The patterns remain robust across alternative measures and econometric techniques. The study provides insightful policy implications for bank managers and regulators in the process of upgrading capital resources to ensure the safety and soundness of the banking industry in an emerging country.

L/C(Letter of Credit) is a common payment term designed to prevent credit risk in international trade. However, most companies prefer T/T (Telegraphic Transfer) payment due to its time and cost efficiency. According to related statistics, more than 70% of international trade contracts are based on T/T rather than other payment terms. The time required from the export negotiation to the completion of the export transaction and collection in international trade is very long. In this process, disputes related to settlement are continuous, so caution should be exercised. Therefore, whether or not the export payment is recovered in a timely manner is the core issue of trade transactions for exporters. The purpose of this study is to identify problems that cause delayed payments during settlement by the remittance (T/T) method, which can lead to settlement risk, in order to investigate those factors which can lead to delays in payments and increased risk as well as to determine ways to prevent such factors in advance. According to empirical findings, trading experience, transaction duration, and contract contents can be important determinants in terms of payment delays. Industry uniqueness and market uncertainty were found to be in opposition to the hypothesized relationships. The results of this study will be useful for trading companies to reduce their payment risk.

Hazardous wastes released into the general environment are of concern to the public and to public health authorities. In response to this concern, the Comprehensive Environmental Response, Compensation, and Liability Act, as amended (commonly called Superfund), was enacted in 1980 to provide a framework for environmental, public health, and legal actions concerning uncontrolled releases of hazardous substances. The Agency for Toxic Substances and Disease Registry (ATSDR) was created by Superfund to address the public health issues of hazardous wastes in the community environment. Two key Agency programs, Public Health Assessments and Toxicological Profiles, are designed to assess the risk to human health of exposures to hazardous substances that migrate from waste sites or through emergency releases (e.g., chemical spills). The Agency's public health assessment is a structured process that permits ATSDR to identify which waste sites or other point sources require traditional public health actions (e.g.. human exposure studies, health studies, registries, health surveillance, health advisories). The ATSDR qualitative public health assessment complements the U.S. Environmental Protection Agency's quantitative risk assessment. For Superfund purposes, both assessments are sitespecific. ATSDR's toxicological profiles are prepared for priority hazardous substances found most frequently at Superfund sites. Each profile presents the current toxicologic and human health effects information about the substance being profiled. Each profile also contains Minimal Risk Levels (MRLs), a type of risk assessment value. This paper covers ATSDR's experience in conducting public health assessments and developing MRLs, and it relates this experience to recommendations on how to improve chemical risk assessments.

As the hydrogen economy receives attention, much research has been conducted on water electrolysis that can produce green hydrogen. After investigating the various risk factors that exist in the alkaline water electrolysis process through hazard and operability study and job safety analysis, which are risk assessments, measures to ensure safety were prepared and made into a manual. Possible risks that could occur during various emergency stop situations and operations were identified, and leakage of potassium hydroxide (KOH) and hydrogen used as electrolyte appeared to be the main risk. If you utilize a risk assessment for the relevant equipment when writing a manual, you will be able to prepare work procedures that substantially reduce risk factors.

The major objective of construction process control(CPC) is to provide construction managers with operational information that will help reduce project duration and save project cost. However, the CPC in Korea is being applied to construction projects with some basic problems such as the inconvenience of CPC S/Ws and the process control unconcerned with construction information classification system and computer system to integrate cost and schedule. This study analyzes the present condition of CPC including the basic problems, and then suggests the reform measures in technical and operational viewpoints to reduce construction risk. The focus of study is on the technical improvement for the application of construction information management system applicable to both cost estimating and schedule management.

Some consumers prefer online and others prefer offline. What makes them prefer online or offline? There has been a lack of theoretical development to adequately explain consumers' channel switching behavior between traditional physical stores and new virtual stores. Through consumers' purchase decision processes, this study examined the reasons why consumers changed channels depending on purchase process stages. Consumer's purchase decision process could be divided into three stages: pre-purchase stage, purchase stage, and post-purchase stage. We used the intention of channel selection as a surrogate dependent variable of channel selection. And some constructs, that is, channel function, channel benefits, customer relationship benefits, and perceived behavioral control, were selected as independent variables. In buying look-and-feel products, it was identified that consumers preferred virtual stores to physical stores at pre-purchase stage. To put it concretely, all constructs except channel benefits were more influenced to consumers at virtual stores. This result implied that information searching function, which is a main function at pre-purchase stage, was better supported by virtual stores than physical stores. In purchase stage, consumers preferred physical stores to virtual stores. Specially, all constructs influenced much more to consumers at physical stores. This result implied that although escrow service and trusted third parties were introduced, consumers felt that financial risk, performance risk, social risk, etc. still remained highly online. Finally, consumers did not prefer any channel at post-purchase stage. But three independent variables, i.e. channel function, channel benefits, and customer relationship benefits, were significantly preferred at physical stores rather than virtual stores at post-purchase stage. So we concluded that physical stores were a little more preferred to virtual stores at post-purchase stage. Through this study, it was identified that most consumers might switch channels according to purchase process stages. So, first of all, sales representatives should decide that what benefits should be given them through virtual stores at the pre-purchase stage and through physical stores at the purchase and post-purchase stages, and then devise collaborative channel strategies.

This paper attempts to identify that the speeding behavior is the important factor in traffic accident by analysing the background and process of speeding behavior. The structure of hurried behavior is reviewed to explain the relationship between the speeding behavior and hurried behavior. And the process of speeding behavior which becomes his own attitude and behavior in driving by social customs approval is analysed by risk homeostasis theory. The results of attitude survey show that drivers speeding behavior is not changing even though they know that speeding behavior is main factor in traffic accident. The influence structure among hurried behavior, background and process of speeding behavior should be analysed to understand the actual speeding behavior in driving.

The size of the OLED material market is expected to grow from $1.1 billion in 2019 to $2.3 billion in 2023, with an average annual sustainable growth of more than 19%. Among the facilities mainly used by OLED material manufacturers, accidents such as fire, explosion, and leakage frequently occur when using filtration equipment, so it is necessary to improve the risk when using filtration equipment. In this study, it was divided into four main processes, namely, assembly and disassembly process, filtration process, wet cake recovery process, and washing process in order to derive the risks associated with the use of filtration equipment. Hazard factors were derived by conducting accident case investigations, preliminary interviews, and surveys. For the analysis of questionnaire results, statistical analysis such as frequency analysis and Pearson chi-square test analysis was performed using SPSS 21, and risk improvement measures were suggested using the analyzed results. It is expected that this study will serve as a basis for dealing with safety and risk factors that may occur as the size of the OLED market expands.

In this study, the Delphi method and AHP (analytic hierarchy process) were used to evaluate tunnel collapse risk from a comprehensive and multifaceted perspective. Influence factors were established through literature reviews, previous studies, and brainstorming sessions with expert groups, resulting in the construction of five main classification systems. A panel of 21 experts was formed, and three rounds of Delphi surveys were conducted to prevent errors and biases in the expert judgment process, thereby enhancing reliability. Ultimately, 14 influence factors were identified through CVR (content validity ratio) and COV (coefficient of variation) analyses of the experts' responses. Subsequently, the AHP method was applied to assess the relative importance of each influence factor and calculate the final composite weights. The timing of support and reinforcement had the highest priority, followed by groundwater inflow, joint conditions, support pattern levels, and auxiliary methods. These findings help identify the key factors affecting tunnel collapse risk and provide a foundation for developing strategies to improve tunnel safety.
