    Abstract Background: The coronavirus disease 2019 (COVID-19) pandemic has been one of the most serious global threats to public health recently. The present study examined whether area deprivation is associated with concerns related to COVID-19 using large nationwide data across South Korea. Methods: We used nationwide 2020 Korea Community Health Survey and official government database. Of the 225,680 included participants, 123,324 (54.6%) were women, and the mean age was 54.9 [17.8] years old. We classified the Area deprivation index (ADI) into Quartile 1 (Least deprived); Quartile 2; Quartile 3; and Quartile 4 (Most deprived). Our primary outcome was the concerns related to COVID-19 (0–16 scores). Multilevel regression analysis was conducted. Results: The mean score of concerns related to COVID-19 was 11.3 [3.2] in the total population. 13.5% of the variability in the scores of concerns related to COVID-19 was accounted for by district areas. Area with Q4 of ADI were associated with an increased score of concerns related to COVID-19 (Q1: reference; Q2: β = 0.218, SE = 0.119, FDR adj.p-value = 0.085; Q3: β = 0.235, SE = 0.133, FDR adj.p-value = 0.094; Q4: β = 0.252, SE = 0.109, FDR adj.p-value = 0.029). 19–49 groups in area with Q4 of ADI were associated with an increase in scores of concerns related to COVID-19 than other age groups in area with Q4 of ADI. Area with Q4 of ADI were associated with a score of concern of being criticized if getting infected compared to area with Q1 of ADI. Conclusion: We found that the highest quartile ADI was associated with greater concerns related to COVID-19. By identifying vulnerable population to concerns related to COVID-19, health systems may consider preventive intervention to mitigate mental health issues.

  3. Article ; Online: Post-processed posteriors for sparse covariances

    Abstract We consider Bayesian inference of sparse covariance matrices and propose a post-processed posterior. This method consists of two steps. In the first step, posterior samples are obtained from the conjugate inverse-Wishart posterior without considering the sparse structural assumption. The posterior samples are transformed in the second step to satisfy the sparse structural assumption through a generalized thresholding function. This non-traditional Bayesian procedure is justified by showing that the post-processed posterior attains the optimal minimax rates under the spectral norm loss in high-dimensional settings. We also propose the post-processed posterior for contaminated data and apply it to the estimation of the sparse idiosyncratic covariance of the approximate factor model. The advantages of our method are demonstrated via a simulation study and a real data analysis with S&P 500 data.

    Abstract Purpose: This article aimed to investigate 1) whether electronic cigarette (EC) users are more likely to experience asthma attacks or emergency room (ER) visits due to asthma than non-users and 2) how age and smoking behaviors moderate the effect size of the association.
    Materials and methods: We used National Health Interview Survey data from 2016-2019. Multiple logistic regression analysis was performed to identify the association between current EC use and having an asthma attack and ER visitation due to asthma. Interaction terms were included to explore the moderation effects of age and cigarette smoking status. Subgroup analysis was conducted according to age group.
    Results: Of the 218911 participants, 2.0% of them experienced an asthma attack, and 0.5% visited the ER due to asthma. Current EC use was associated with higher odds of having an asthma attack. In interaction analysis, age and smoking status were identified as a moderator in the relationship between EC use and asthma attacks. Participants in their 20s or 30s showed the highest interaction effect.
    Conclusion: Our analysis indicates the potential impact of EC use on public health and the moderating effects of smoking behavior.

    Abstract The platform developed in this study provides users with mental and physical health status monitoring services. Recently, it has been difficult for people with various respiratory diseases and mental health conditions to receive regular examinations/observation from specialized medical institutions. Therefore, in this study, because the need for the continuous health status measurement/monitoring of subjects was recognized, a device for constantly monitoring trends and changes in blood oxygen saturation was developed to ensure safety. Oxygen saturation below 90 indicates an emergency. In addition, we conducted a hypothesis test for analyzing the relationship between sensor data and depression and anxiety. The sensor data used in the research were location, gyroscope metrics, touch, data usage, and sleep mode from a smartphone. Correlation analysis and multiple regression analysis were conducted to analyze the relationship between the collected sensor data and depression and anxiety. As a result of the research, it was found that among the general characteristics, income, location, sleep duration, and gyroscope were found to have a negative effect on depression and anxiety, whereas touch was shown to have a positive (+) effect. It was confirmed that sensor data measured over runtime can be used as information that can explain users’ depression and anxiety.

    Abstract In this study, we investigated the influence of quasi-one-dimensional (Quasi-1D) characteristics on the source and drain contact resistances within vertical nanowire (NW) field-effect transistors (FETs) of diminutive diameter. The top contact of the NW is segregated into two distinct regions: the first encompassing the upper surface, designated as the axial contact, and the second encircling the side surface, known as the radial contact, which is formed during the top-contact metal deposition process. Quantum confinement effects, prominent within Quasi-1D NWs, exert significant constraints on radial transport, consequently inducing a noticeable impact on contact resistance. Notably, in the radial direction, electron tunneling occurs only through quantized, discrete energy levels. Conversely, along the axial direction, electron tunneling freely traverses continuous energy levels. In a meticulous numerical analysis, these disparities in transport mechanisms unveiled that NWs with diameters below 30 nm exhibit a markedly higher radial contact resistance compared to their axial counterparts. Furthermore, an increase in the overlap length (less than 5 nm) contributes to a modest reduction in radial resistance; however, it remains consistently higher than the axial contact resistance.
