The relationship between natural cycles and human actions in causing climate change and its impacts on society have been a subject of debate. This paper explores the responses of pre-modern Koreans to climate change and natural disasters. The focus of this paper is on the societal reactions to these natural calamities and disasters during the Koryŏ dynasty (936–1392 A.D.) and their influence on Korea afterwards. This paper investigates the reasons behind the retention of primal religious worldviews in the face of ecological crises while other major imported religions were abandoned. The research method involved in this paper is archival research, and the literature sources include ancient records and other ecotheological resources. Through an analysis of the archival research and ecotheological resources, this study sheds light on the interpretation of climatic events in pre-modern Korea. Furthermore, based on the research findings, it presents missional implications for the Korean church in the post-pandemic era. This study underscores the importance of the church's responses to environmental awareness, collective responsibility, and spiritual support in addressing the challenges of climate change and provides missional implications for the Korean Church in response to the post-COVID-19 era based on the results of the research.

This paper attempts to explore the public dimension of religion in Korea. First, it examines the Western and East Asian contexts on the concept of 'public', noting that the gap in notions of public is large between East Asian and Western traditions. The following section discusses Habermas' 'institutional translation proviso' in relation to the notion 'public'. The institutional translation proviso serves as the basis for further discussion on rethinking the public role of religion in Korea in the era of climate crisis. We argue that 'secular' translations of religious convictions can help religious citizens and communities engage in public discourses on ecological challenges. We then consider major limitations of Habermas' understanding of religion. In the following section, we move on to discuss Albert Schweitzer and process theology in order to demonstrate how religious languages can be reinterpreted on the basis of modern experiences of ecological challenges. We then consider Buddhist alternatives for overcoming the climate crisis. The final section introduces José Casanova's account of public religions and discusses its implication for envisioning the public role of religious organizations in ecological efforts. Reviewing the contributions made by religious organizations to the Korean society, we suggest that 'ecological publicness' of religion can be obtained. [ABSTRACT FROM AUTHOR]

As climates change around the world, concern regarding environmental pollutants emitted into the atmosphere is increasing. The cement industry consistently produces more than 4000 million metric tons of cement per year. However, the problem of air pollutants being emitted from the calcination process is becoming more critical because their amount increases proportionally with cement production. Each country has established regulatory standards for pollutant emission. Accordingly, the cement industry is equipped with facilities to reduce air pollutants, one of which is the NOx removal process. NOx reduction processes under combustion conditions are modified to minimize NOx generation, and the generated NOx is removed through post-treatment. In terms of NOx removal efficiency, the post-treatment process effectively changes the combustion conditions during calcination. Selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) processes are post-treatment environmental facilities for NOx reduction. Accordingly, considering the stringent NOx emission standards in the cement industry, SNCR is essential, and SCR is selectively applied. Therefore, this paper introduces nitrogen oxide among air pollutants emitted from the South Korean cement industry and summarizes the technologies adapted to mitigate the emission of NOx by cement companies in South Korea.

As incidences of food poisoning, especially norovirus-induced diarrhea, are associated with climate change, there is a need for an approach that can be used to predict the risks of such illnesses with high accuracy. In this paper, we predict the winter norovirus incidence rate in Korea compared to that of other diarrhea-causing viruses using a model based on B-spline added to logistic regression to estimate the long-term pattern of illness. We also develop a risk index based on the estimated probability of occurrence. Our probabilistic analysis shows that the risk of norovirus-related food poisoning in winter will remain stable or increase in Korea based on various Representative Concentration Pathway (RCP) scenarios. Our approach can be used to obtain an overview of the changes occurring in regional and seasonal norovirus patterns that can help assist in making appropriate policy decisions. [ABSTRACT FROM AUTHOR]
