Reduction in Floor Impact Noise Using Resilient Pads Composed of Machining Scraps.

Floor impact noise is a significant social concern to secure a quiescent living space for multi-story building residents in South Korea. The floating floor, consisting of a concrete structure on resilient pads, is a specifically designed system to minimize noise transmission. This floating structure employs polymeric pads as the resilient materials. In this study, we investigated the utilization of helically shaped machining scraps as a resilient material for an alternative approach to floor noise reduction. The dynamic elastic modulus and loss factor of the scrap pads were measured using the vibration test method. The scrap pads exhibited a low dynamic elastic modulus and a high loss factor compared to the polymeric pads. Heavyweight impact sound experiments in an actual building were conducted to evaluate the noise reduction performance. The proposed pads showed excellent performance on the reduction in the structure-borne vibration of the concrete slab and resulting sound generation. The analytical model was used to simulate the response of the floating floor structure, enabling a parametric study to examine the effects of the resilient layer viscoelastic properties. Both experimental and analytical evidence confirmed that the proposed scrap pads contribute to the development of sustainable solutions for the minimization of floor impact noise.

Performance of ChatGPT in the In-Training Examination for Anesthesiology and Pain Medicine Residents in South Korea: Observational Study.

ChatGPT has been tested in health care, including the US Medical Licensing Examination and specialty exams, showing near-passing results. Its performance in the field of anesthesiology has been assessed using English board examination questions; however, its effectiveness in Korea remains unexplored. This study investigated the problem-solving performance of ChatGPT in the fields of anesthesiology and pain medicine in the Korean language context, highlighted advancements in artificial intelligence (AI), and explored its potential applications in medical education. We investigated the performance (number of correct answers/number of questions) of GPT-4, GPT-3.5, and CLOVA X in the fields of anesthesiology and pain medicine, using in-training examinations that have been administered to Korean anesthesiology residents over the past 5 years, with an annual composition of 100 questions. Questions containing images, diagrams, or photographs were excluded from the analysis. Furthermore, to assess the performance differences of the GPT across different languages, we conducted a comparative analysis of the GPT-4's problem-solving proficiency using both the original Korean texts and their English translations. A total of 398 questions were analyzed. GPT-4 (67.8%) demonstrated a significantly better overall performance than GPT-3.5 (37.2%) and CLOVA-X (36.7%). However, GPT-3.5 and CLOVA X did not show significant differences in their overall performance. Additionally, the GPT-4 showed superior performance on questions translated into English, indicating a language processing discrepancy (English: 75.4% vs Korean: 67.8%; difference 7.5%; 95% CI 3.1%-11.9%; P=.001). This study underscores the potential of AI tools, such as ChatGPT, in medical education and practice but emphasizes the need for cautious application and further refinement, especially in non-English medical contexts. The findings suggest that although AI advancements are promising, they require careful evaluation and development to ensure acceptable performance across diverse linguistic and professional settings.

지방선거에서 중국인 등 외국인 영주권자 선거권 배제 필요성에 관한 연구

In 2005, during the Roh Moo-hyun administration, South Korea gave foreigners the right to vote for local council members and heads of local governments. Koreans living in China cannot cast a single vote in elections held in China. Foreign permanent residents residing in South Korea can vote after only three years. The number of Chinese permanent residents in South Korea is approximately 150,000, and the number of permanent residents who are foreigners and can participate in elections in 2026 is expected to be 181,251. This can be said to be an example of deviating from the principle of reciprocity in that one can vote in Korean local elections even if one does not have Korean nationality. The current law has some unreasonable aspects and is not fair from the perspective of reciprocity. Additionally, there have been attempts by China to interfere in elections in Australia and Canada, and voices of concern about Chinese political intervention are growing. These laws that violate reciprocity must be revised. Based on the principle of reciprocity voting rights for foreign permanent residents including Chinese should be excluded.

Confirmation bias, information selection, and belief reinforcement about the safety/risk of nuclear spent fuel storage facilities

This study investigates the phenomenon of confirmation bias in information selection in the context of nuclear spent fuel (NSF) storage facilities. An online survey was administered to a sample of 321 residents in South Korea. They were asked to assess their beliefs about the safety/risk of NSF storage facilities before and after their exposure to additional information. Our findings show a positive association between the initial belief and confirmation bias, suggesting that the research participants tend to select articles consistent with their beliefs about the safety/risk of the facility. Trust in government is negatively related to confirmation bias, implying that residents with a greater level of trust in government are more likely to choose information opposing their initial beliefs. Finally, this study finds the self-reinforcing and potentially polarizing nature of individuals' beliefs about the safety/risk of NSF storage facilities as residents’ initial beliefs are reinforced rather than challenged after they reviewed self-selected articles. Implications for public policy and communication strategies related to improving the acceptance of NSF storage facilities are discussed.

Public attitudes towards co-ethnic migrant integration: evidence from South Korea

ABSTRACT What can public attitudes towards the integration of co-ethnic migrants teach us about social integration in newly diverse societies? Research finds that South Koreans prefer co-ethnic migrants from culturally similar or desirable origins, but it says little about the integration of migrant groups. Existing data and qualitative studies suggest considerable barriers to fully incorporating otherwise preferred migrants. Focusing on integrating North Korean migrants in South Korea – a relatively privileged migrant group that enjoys substantial resettlement support but encounters barriers to full integration – this paper addresses the research gap by testing competing explanations of migrant incorporation. Informed by Intergroup Threat Theory (ITT), the study examines how threats defined as realistic or symbolic shape native attitudes toward these migrants. Using a conjoint survey experiment to measure preferences for economic, political, and social integration, we find South Koreans favor North Korean migrants with extended residence in South Korea, which is a marker for diminishing realistic and symbolic intergroup threats. Conversely, migrants signaling stronger affiliations to North Korea or lacking diverse social ties in South Korea fail to alleviate intergroup threat concerns and consequently face discrimination. Our findings offer insights into integration policy and contribute to the migration and citizenship literature and contemporary Korean Studies.

Comparative Analysis of Driver Mutations and Transcriptomes in Papillary Thyroid Cancer by Region of Residence in South Korea.

Radiation exposure is a well-known risk factor for papillary thyroid cancer (PTC). South Korea has 24 nuclear reactors in operation; however, no molecular biological analysis has been performed on patients with PTC living near nuclear power plants. We retrospectively included patients with PTC (n=512) divided into three groups according to their place of residence at the time of operation: inland areas (n=300), coastal areas far from nuclear power plants (n=134), and nuclear power plant areas (n=78). After propensity score matching (1:1:1) by age, sex, and surgical procedure, the frequency of representative driver mutations and gene expression profiles were compared (n=50 per group). Epithelial-mesenchymal transition (EMT), BRAF, thyroid differentiation, and radiation scores were calculated and compared. No significant difference was observed in clinicopathological characteristics, including radiation exposure history and the frequency of incidentally discovered thyroid cancer, among the three groups. BRAFV600E mutation was most frequently detected in the groups, with no difference among the three groups. Furthermore, gene expression profiles showed no statistically significant difference. EMT and BRAF scores were higher in our cohort than in cohorts from Chernobyl tissue bank and The Cancer Genome Atlas Thyroid Cancer; however, there was no difference according to the place of residence. Radiation scores were highest in the Chernobyl tissue bank but exhibited no difference according to the place of residence. Differences in clinicopathological characteristics, frequency of representative driver mutations, and gene expression profiles were not observed according to patients' region of residence in South Korea.

Apartment Space Planning Directions for Infectious Disease Prevention and Management: Insights Based on Residents’ Experiences

The COVID-19 pandemic has raised people’s interest in pandemic-safe housing. This study aims to present insights into apartment housing space design to prevent and manage infectious diseases based on the actual living experiences of apartment residents. The relevant literature was reviewed, and overall satisfaction was assessed through a questionnaire targeting apartment residents in South Korea. Finally, using the photovoice method, residents’ space needs were identified. By applying a mixed-use methodology and identifying the needs of residents, the following two recommendations were derived: (1) a flexible space plan to support multifunctional use while securing work efficiency and privacy in the living room, bedroom, and space for hobbies/work/learning; (2) a facility for removing contaminants at the entrance with sufficient storage space. The residents emphasized the importance of non-structural changes to the space and the convenience of use to increase actual space utilization. When planning future pandemic-safe apartment housing spaces, it is important to consider structural aspects like functionality and facilities. Convenience of use and methods of supporting family members’ privacy should also be taken into account.

The rocky road to freedom: number of countries transited during defection and risk of metabolic syndrome among North Korean Refugees in South Korea

ObjectivesNorth Korean Refugees (NKRs) undergo defection, and this has been shown to impact their current health status in South Korea. However, little is understood about how the defection process is related to metabolic syndrome (MetS). This study regarded the defection process to be a quasi-measurement of traumatic experience and investigated whether defection was a risk factor for MetS among NKRs living in South Korea. Study designThis cross-sectional study obtained data from the Korea University Anam Hospital in Seoul. NKRs (N = 847) voluntarily completed questionnaires and underwent at least one medical examination between October 2008 and July 2021. MethodsMultivariable logistic regression models were used to evaluate whether the number of countries transited by NKRs was associated with MetS by controlling for covariates. ResultsThe prevalence of MetS among male and female NKRs in South Korea was 12.3% and 13.3%, respectively. The highest prevalence of MetS (33.4%) was among NKRs who had transited two countries. The number of months in transit countries (mean: 49.9 ± 51.7) and period of residence in South Korea (mean: 40.9 ± 40.9 months) were also considered. NKRs who transited three countries had a higher probability of MetS (odds ratio [OR] 2.660, 95% confidence interval [CI] 1.161–6.097) than those who travelled directly to South Korea. NKRs who transited three countries and had only resided in South Korea for a short period had a higher probability of MetS (OR 3.424, 95% CI 1.149–10.208) than those who have lived in South Korea for a longer period. ConclusionsConsidering the social vulnerability of NKRs and consequential health problems, there is an urgent need for appropriate support from the government and society.

A Pilot Study of a Game-Based Cognitive Training Intervention for Public Senior Housing Residents in South Korea

The current study investigated the effects of a game-based intervention on cognitive function and mood for older adults in South Korea. In a nonrandomized controlled, pretest-posttest study, sixteen older adults were allocated to an intervention or control group. The intervention group received the 10-week cognitive training using Happy Table. The game-based cognitive training intervention significantly improved cognitive function and memory loss, whereas the control group maintained a similar level of impairment. However, there were no significant changes in anxiety and depression for both groups. The implementation of game-based intervention may be promising for improving cognitive abilities for older adults.

Age-specific Risk of SARS-CoV-2 Reinfection During Omicron Outbreaks, South Korea.

We assessed the risk of reinfection among all residents in South Korea who tested positive for coronavirus disease 2019 from January to August 2022. Children 5-11 years [adjusted hazard ratio (aHR) = 2.20], and 12-17 years old (aHR = 2.00), were at higher risk; whereas 3-dose vaccination (aHR = 0.20) lowered the risk of reinfection.

Dietary supplement use and its related factors among Chinese international and Korean college students in South Korea.

The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. We conducted online surveys of 400 Chinese international students and 452 Korean college students from January to February 2021. We analyzed the factors related to the use of dietary supplements by these students using multi-group structural equation modeling and logistic regression analysis. Approximately 65% of the Chinese international students and 93% of the Korean college students consumed dietary supplements at least once in the year preceding the survey. The common types of dietary supplements consumed by both groups of students were vitamin and mineral supplements, Lactobacillus products, and red ginseng products. Structural equation modeling showed that perception of the consumption of dietary supplements by family and friends positively influenced attitude toward dietary supplements. This effect was higher for Korean college students than for Chinese international students (P < 0.01). Attitude toward dietary supplements positively influenced their use, and this effect was higher for Chinese international students than for Korean college students (P < 0.001). Logistic regression analysis showed that the use of dietary supplements by Chinese international students was significantly associated with age, self-reported health status, interest in health, perception of and attitude toward dietary supplements, and length of residence in South Korea. Among Korean college students, it was associated with exercise frequency and attitude toward dietary supplements. This study showed significant differences in the use of dietary supplements and related factors between Chinese international and Korean college students. Therefore, nutrition education programs on dietary supplements need to have differentiated content for each group. Such differences also suggest that the industry should consider the relevant characteristics of college students while developing and marketing dietary supplements.

The Food Delivery App Information Design Suggestion for Foreigners in South Korea

Many foreigners living in South Korea faces various problems in their daily lives, such as language barriers, cultural differences, etc. This also applies to making food orders via mobile applications. A lot of foreigners have difficulties using food delivery apps for various reasons. The purpose of this study is to create a functional design of food delivery app for foreigners based on a survey. As a part of this study, we conducted a survey among foreign residents in South Korea to identify and analyze user needs. After analyzing the survey results, we proposed a mobile app design based on user experience. As a result, we created a new design interface that includes a full English translation of the entire menu and information about food allergens. Besides, information about nutrients, ingredient’ origin, the pungency indicator and the label of vegan and halal food also have been added to the application interface.

Efficient Energy Saving Scenarios for Indoor PM2.5 Management in an Apartment of South Korea.

Indoor PM2.5 must be effectively controlled to minimize adverse impacts on public health. Cooking is one of the main sources of PM2.5 in residential areas, and indoor air quality (IAQ) management methods such as natural and mechanical ventilation, range hood, and air purifier are typically used to reduce cooking-generated PM2.5 concentrations. However, studies on the combined effects of various IAQ management methods on indoor PM2.5 reduction and energy consumption are limited. In this study, a theoretical model was established to estimate the performance of various IAQ management methods for controlling indoor PM2.5 concentrations and energy consumption. The model was verified by comparative experiments in which, various IAQ management methods were operated individually or combined. Seasonal energy consumption was calculated through the verified model, and energy consumption saving scenarios were derived for maintaining indoor PM2.5 concentrations less than 10 μg/m3, a World Health Organization annual guideline, under fair and poor outdoor PM2.5 concentrations of 15 and 50 μg/m3, respectively. Based on our results, we found that energy consumption could be reduced significantly by applying natural ventilation in spring, autumn, and summer and mechanical ventilation in winter. Our study identified efficient energy saving PM2.5 management scenarios using various IAQ management methods by predicting indoor PM2.5 concentration and energy consumption according to the annual life patterns of typical residents in South Korea.

Reinfection with SARS-CoV-2 in general population, South Korea; nationwide retrospective cohort study.

To better understand the epidemiology of SARS‐CoV‐2 reinfections, we analyzed national data from South Korean who were followed longitudinally from January 2020 to April 2022. We conducted a nationwide retrospective cohort study to estimate possible SARS‐CoV‐2 reinfection rates in all residents in South Korea, with at least two episodes of laboratory‐confirmed SARS‐CoV‐2 infection by reverse‐transcriptase polymerase chain reaction or rapid antigen test (RAT) performed at least 45 or more days between both episodes, between January 2020 and April 2022. There were 16 130 855 laboratory‐confirmed SARS‐CoV‐2 cases in South Korea, with 55 841 (346.2 per 100 000; or 0.3% of all infections) cases of possible reinfections. The reinfection rate has increased from 6.0 cases per 100 000 during Pre‐Delta period to 128.0 cases per 100 000 and 355.1 cases per 100 000 during Delta and Omicron periods, respectively. Persons with one dose of vaccination had the highest reinfection rate of 642.2 per 100 000, followed by unvaccinated persons (536.2/100 000) and two‐dose vaccinated persons (406.3/100 000). Our finding suggests that the majority of possible reinfections occurred following the emergence of new variants.

Factors influencing the community capacity of rural residents in South Korea

ABSTRACT This research aims to identify the factors that influence community capacity as it affects the mobilisation of inner resources and community conflict management for community residents. Data from an on-site survey consisting of self-administered questionnaires were obtained from 339 community residents in rural areas of South Korea. Factor analysis identified four dimensions: problem assessment, leadership, connections and self-help. Education, income, length of residence, as well as participation in agricultural cooperatives, community development organisations and hobby organisations were significant factors in influencing individuals having positive or negative attitudes and abilities associated with community capacity. Conclusions suggest that community development specialists and policymakers should consider these factors to understand individuals participation in community-based organisations in order to build community capacity.

High prevalence of depression and sleep–wake disorders among female emergency medicine residents in South Korea

Background Depression and sleep–wake disorders are recognized as one of the major problems among emergency physicians. While depression is more common in females than in males, the associated factors linking depression and sleep–wake disorders in emergency physicians, particularly females, remain unknown. Objective To analyze the prevalence of depression and sleep–wake problems among emergency medicine (EM) residents in South Korea and to identify the gender differences and situations that adversely predispose female residents to mental health problems. Methods We conducted a cross-sectional analysis using the data collected from the 2019 National EM Residents Wellness Survey targeting all of 630 EM residents in South Korea. The survey included variables potentially influencing depression and sleep–wake problems, such as personal characteristics, work-related stress, and extrinsic environment. Information regarding medical conditions, depression, job stress, and sleep deprivation was obtained using the self-administered Patient Health Questionnaire (PHQ-9), the Apgar Wellness Score (AWS), and the Epworth Sleepiness Scale (ESS). We analyzed the data using IBM SPSS Statistics version 25 and MedCalc version 17. Results A total of 384 residents participated in the survey. Overall, 27.5% of the EM residents met the criteria for at least moderate depression and 36.9% of the EM residents had sleep-related problems. We found that difficulty in trading the shift schedule and frequent night shifts was associated with depression (p = .001, p = .005; respectively). Female residents demonstrated an increased risk of depression and sleepiness compared to their male counterparts (odds ratio [OR] 1.95, OR 1.81; respectively). In addition, logistic regression analysis revealed significant differences by gender in depression with regards to flexibility of trading shifts (p = .005), level of training in the emergency medical centre (p = .035), and frequent night shifts (p = .010). Conclusions Approximately, one-third of EM residents report depression and sleep–wake problems, with female residents showing a higher risk than male residents. Several risk factors were identified, and future strategies should be aimed to address these issues to improve the training environment and overall wellbeing of EM residents. KEY MESSAGES The prevalence of depression and sleep-related problems were, respectively, 1.95 and 1.81 times higher in female residents compared to their male colleagues. The associated risk factors for depression were flexibility of shift trade, level of training in the emergency medical centre, and frequency of night shifts. Improving the training environment and facilities, as well as offering more flexible duty trading options can provide potential opportunities to reduce the risk.

Roles of travel and leisure in quality of life during the COVID-19 pandemic

ABSTRACT Amid the COVID-19 pandemic, our indoor and outdoor leisure activities have profoundly changed. However, research on the way people negotiate leisure motivations with constraints and the relationship between leisure and quality of life during the COVID-19 pandemic is scant. On the basis of in-depth interviews with 32 residents in South Korea in 2020, this study reveals that they proactively overcome leisure constraints; their leisure activities are not reduced but slightly modified (e.g. watching baseball games online vs. at a ballpark) or even increased (e.g. camping). When people articulate quality of life during the pandemic, work, health, and family are more salient themes than leisure and travel. Such finding is incongruent with previous research emphasising the importance of leisure and vacations in the quality of life. This study extends the model of leisure constraints negotiation to the context of a pandemic and advances our understanding of the multi-dimensional nature of the quality of life.

A Site of Bounded Imaginaries: Local Narratives of Buan after Protests against a Nuclear Waste Repository

This paper examines a historical case where local residents in South Korea had been alienated from the decision-making processes in nuclear policy as their sociotechnical visions remained marginalized. Narratives of nuclear experts, activists in environmental NGOs (ENGOs), and local residents supporting or resisting against the siting of a repository in a southwestern rural town, Buan, from 2003 to 2005 were used for our comparative textual analyses. Imaginaries of desirable forms of life and order that constitute nationally-shared visions of “good society” profoundly delimit the shapes of futures by enabling key political decisions of a nation. With our findings, we argue that ethical problems of how to recognize and compensate for what has already happened to people around (candidate) sites of nuclear facilities remains a source of latent social conflict. Buan residents’ visions of a “good society” attainable through their practices around nuclear technology were collectively held and publicly narrated yet failed to become widely shared in the nation. If local people’s understanding of what the past has been and what the future should be like continue to stay marginalized, Korean nuclear governance with participatory initiatives will remain in its current form of “partial” inclusiveness.

Transboundary air pollution and health: evidence from East Asia

AbstractOutdoor air pollution continues to be a challenging health issue, even as countries experience economic growth. By exploiting a unique transboundary setting in East Asia, we study the impact of an increase in particulate matter (PM) concentrations on fetal deaths. Due to the westerlies in the mid-latitudes, residents in South Korea at times experience intermittent exposure to high levels of air pollution. Using such atmospheric setting, we estimate a reduced-form impact of high PM events on fetal deaths, which capturesin uteroexposure to pollution. Controlling for local weather and pollution trends, regression results indicate that high PM events in Beijing lead to a significant increase in daily fetal mortality rates in Korea, by approximately 7.4 per cent. This research finding provides lower-bound estimates of not only negative spillovers manifested in fetal health but also the impact of pollution on the health of the Chinese population and calls for a need to tackle transboundary air pollution via international cooperation.
