OBJECTIVE: The COVID-19 pandemic continues to pose significant challenges to nations. The Korean government aimed to mitigate the spread of COVID-19 through stay-at-home strategies and maintaining social distance, which are likely to result in major changes in the lifestyle, mental health, and quality of life of citizens. This study aimed to investigate the impact of the COVID-19 pandemic on these factors in Koreans over 20 years old. METHODS: The study sample consisted of 104 adults in South Korea aged over 20 years. An online survey was conducted between August and October 2020, in which participants were asked to complete the Yonsei Lifestyle Profile to assess lifestyle changes, the Center for Epidemiological Studies-Depression Scale, and the World Health Organization Quality of Life Scale abbreviated version. To investigate the changes in people's lifestyles, depression, and quality of life post COVID-19, descriptive statistics were calculated for these indicators before and after the onset of the pandemic. The p-value was two-sided, and values <0.05, were regarded as statistically significant. RESULTS: There was a significant decline in physical and other meaningful activities, including activities of daily living, leisure, social activity, and education. However, there were no significant changes in nutrition, except in the consumption of carbohydrates and minerals. Participants reported that their quality of life and mental health had decreased after the pandemic struck. CONCLUSIONS: We obtained novel data on the changes in the lifestyle, mental health, and quality of life of South Korean adults before and after the onset of the pandemic. The results of our study may assist health policymakers and practitioners in the development of health education or relevant interventions to deal with the pandemic situation as well as future crises.

With the adoption of new technologies, more risk is introduced into modern society. Important decisions about new technologies tend to be made by specialists, which can lead to a mismatch of risk perception between citizens and specialists, resulting in high social cost. Using contingent valuation methods, this paper analyzes the relationship between willingness to pay (WTP) and the factors expressed through people's image of nuclear power plants (NPP), their perception of NPP safety, and how these can be affected by their scientific background level. Results indicate that groups with a high scientific background level tend to have low risk perception level, represented through their image and safety levels. Further, the results show that mean WTP is dependent on scientific background and image levels. It is believed that these results could help decision makers address the mismatch of trust between the public and specialists in terms of new policy.

Reliable information through instrumentation systems is essential in mitigating severe accidents such as the one that occurred at the Fukushima Daiichi nuclear power plant. There are five elements which might pose a potential threat to the reliability of parameter detection at nuclear power plants during a severe accident: high temperature, high pressure, high humidity, high radiation, and missiles generated during the evolution of a severe accident. Of these, high temperature apparently poses the most serious threat, since thin shielding can get rid of pressure, humidity, radiation (specifically, alpha and beta radiations), and missile effects. In view of this fact, our study focused on designing an instrument transmitter protecting device that can eliminate the high-temperature effect on transmitters to maintain their functional integrity. We present herein a novel concept for designing such a device in terms of heat transfer model that takes into account various heat transfer mechanisms associated with the device.

"A detailed examination of the "Korean development model" from its urban dimension, evaluating its sociopolitical contexts and implications for international development cooperation. There is an increasing tendency to use the development experience of Asian countries as a reference point for other countries in the Global South. Korea's condensed urbanization and industrialization, accompanied by the expansion of new cities and industrial complexes across the country, has become one such model, even if the fruits of such development may not have been equitably shared across geographies and generations. The chapters in this book critically reassess the Korean urban development experience from regional policy to new town development, demonstrating how these policy experiences were deeply rooted in Korea's socioeconomic environment and discussing what can be learned from them when applying them in other developmental contexts. This book will be of great interest to scholars and researchers in the field of urban studies and developmental studies in general and in Korea's (urban) development experience in particular"--

When a first child is born into a family, major changes occur in the lives of first time parents, and this is especially the case for new mothers. Previous research has illustrated that social support can help new mothers better understand and meet the demands of child care and parenting. In this study, the sources and types of social support reported by new mothers were compared to that of the grandmother in two generations of 301 mother-daughter pairs in three cultures (Korea, Hong Kong, and the United States). The results show that for young mothers in Korea, the primary source of support came from mothers or mothers-in-law; whereas the primary source of support for young mothers in both Hong Kong and the United States came from their husbands. The Korean data from the grandmothers reflects a patriarchal pattern, in that the husband's mother provided the most support and help. This was not the case in Hong Kong or the United States. Content of support for new mothers (categorized into physical care, active interaction with the child, and emotional support) differed greatly by source of support (e.g. husband, mother, or mother-in-law) and by culture. These generational and societal differences are interpreted as reflecting both rapid social change and contrasting cultural emphases on marital and extended family relationships. Kin support is more evident in Korea, whereas in Hong Kong and the United States, the relationship between husbands and wives is emphasized.
