Variation simulation and diagnosis considering in-plane/out-of-plane welding distortion

Geometric variation including welding distortion accumulates as many parts are joined together, ultimately affecting the final product. This variation is then subjected to correction, which requires considerable effort, time, and cost. This variation can be categorized as in-plane/out-of-plane variation. To date, studies on variation simulation have largely focused on the out-of-plane variation, however the variation generated in the in-plane direction requires more time and efforts to correct afterwards. This research aims to construct a variation simulation model considering both the in-plane and out-of-plane variations. A geometric analysis was performed to derive an equation that reflects the coupling effect of the out-of-plane variation on the in-plane variation. The proposed model is validated with case study analysis and the results shows that good fidelity in predicting and diagnosing the in-plane variation during the block assembly process considering welding distortion.

Influence of social responsibility and pandemic awareness of nursing students on COVID-19 preventive behaviours: a cross-sectional online survey in South Korea

Objectives Factors influencing COVID-19 preventive behaviour require exploration to strengthen the response competencies of prehealthcare professionals and reduce the pandemic’s impact. This study aimed to identify the level of COVID-19 preventive behaviour among Korean nursing students and to determine the influence of social responsibility and pandemic awareness to present educational strategies for reducing disaster impact.Methods and analysis As a cross-sectional descriptive survey study using an online questionnaire, the participants were convenience sampled from one online community for nursing students and three nursing colleges located in Seoul, South Korea. The data from 590 participants were analysed by t-test, analysis of variance, Pearson’s correlation and linear multiple regression using SPSS.Results The factors influencing COVID-19 preventive behaviour were identified to be social responsibility (linear regression coefficient 0.354, 95% CI 0.243 to 0.464), pandemic awareness (linear regression coefficient 0.131, 95% CI 0.025 to 0.237), impact of COVID-19 on daily life (linear regression coefficient 0.085, 95% CI 0.019 to 0.152) and living in Daegu/Gyeong-buk area (linear regression coefficient 0.134, 95% CI 0.024 to 0.244).Conclusion Based on the findings that social responsibility and pandemic awareness are key predictors of COVID-19 preventive behaviour, customised educational programmes and additional studies are recommended for raising social responsibility and pandemic awareness among prehealthcare professionals as a part of disaster response

The Determinants of Adherence to Public Health and Social Measures Against COVID-19 Among the General Population in South Korea: National Survey Study

BackgroundThe COVID-19 pandemic has created devastating health, social, economic, and political effects that will have long-lasting impacts. Public health efforts to reduce the spread of COVID-19 are the priority of national policies for responding to the pandemic globally. Public health and social measures (PHSMs) have been shown to be effective when used alone or in combination with other measures, reducing the risk of spreading COVID-19. However, there is insufficient evidence on the status of compliance with PHSMs in the general population for the prevention of COVID-19 in public areas, including Korea. ObjectiveThe aim of this study was to assess levels of compliance with the recommended PHSMs against SARS-CoV-2 infection and their predictors among the general population by using national data. MethodsThis study was a secondary data analysis of the National Survey of Infectious Disease Preventive Behaviors in Community, which was conducted by the Korea Centers for Disease Control and Prevention Agency (KDCA) between October 12 and October 30, 2020. The primary study was cross-sectional, using stratified sampling via an adjusted proportional allocation method to select representative samples and ensure the stability of samples. The data were collected through phone interviews conducted by trained enumerators using a structured questionnaire. PHSM adherence was measured using a 10-item comprehensive infectious disease prevention behavior (CIDPB) scale, and each sociocognitive factor, including perceived susceptibility to SARS-CoV-2 infection, perceived severity of SARS-CoV-2 infection, perceived confidence in performing preventive behaviors related to COVID-19, information comprehension ability, and trust in information from the KDCA, was measured. A total of 4003 participants were included in the final analysis. Tobit regression and a decision tree analysis were performed to identify the predictors of preventive measures and the target groups for intervention. ResultsWe discovered that women scored 1.34 points higher on the CIDPB scale than men (P<.001). Compared to the group aged 19 to 29 years, those aged 50 to 59 years and those older than 60 years scored 1.89 and 2.48 points higher on the CIDPB scale (P<.001), respectively. The perceived severity of infection, confidence in preventive behaviors, information comprehension ability, and trust in information from the KDCA were significant positive determinants of CIDPBs (P<.001). The perceived susceptibility to infection showed a significant negative relationship with CIDPBs (P<.001). ConclusionsFemale sex, older age, lower income, and sociocognitive factors were found to be significant determinants of adhering to PHSMs. The findings suggest the need for tailored interventions for target groups; specifically, the age group that was the most active at work indicated the highest potential to spread infection. Adequate public health education and health communication for promoting adherence to PHSMs should be emphasized, and behavior change strategies for those with low perceived confidence in performing PHSMs should be prioritized

The Sequential Mediating Effects of Dietary Behavior and Perceived Stress on the Relationship between Subjective Socioeconomic Status and Multicultural Adolescent Health

Studies have examined the impact of social determinants of health on the health behaviors and health statuses of ethnic minority adolescents. This study examines the subjective health of this population by examining the direct effects of multicultural adolescents’ subjective socioeconomic status (SES) and the sequential mediating effects of their dietary behaviors and perceived stress. We utilized secondary data of 500 middle school students from multicultural families who participated in the 15th Korean Youth Health Behavior Survey, 2019. Information about SES, perceived stress, subjective health status, and dietary behavior (measured by the breakfast intake frequency during the prior week) were utilized. For the relationship between the SES and the subjective health status, we confirmed the sequential mediating effects of breakfast frequency and perceived stress using SPSS 25.0 and PROCESS macro with bootstrapping. The results showed that SES had a direct effect on subjective health status and indirectly influenced subjective health status through the sequential mediating effect of breakfast frequency and perceived stress. However, SES had no direct effects on perceived stress. These findings emphasize that broadening the community-health lens to consider the upstream factor of SES when preparing health promotion interventions is essential to achieving health equity for vulnerable populations

Correlates of Physical Activity in Urban Midwestern African-American Women

Background: African-American women are at higher risk than white women of cardiovascular disease and stroke. In addition, fewer African-American women reap the cardiovascular benefits of exercise, because of low physical activity. The study goals were to identify personal, social environmental, and physical environmental correlates of physical activity of urban dwelling, Midwestern, African-American women and to obtain their recommendations for increasing exercise in their communities. Methods: A face-to-face interview (Women and Physical Activity Survey) covering personal, social environmental, and physical environmental correlates of physical activity was administered to 399 volunteer African-American women aged 20 to 50 years, living in Chicago. Physical activity was measured with questions on lifestyle and planned leisure-time activity (exercise) from the Behavioral Risk Factor Surveillance System. Results: The women were from a wide socioeconomic spectrum of education and income. Forty-two percent of the women met current recommendations for moderate or vigorous physical activity; 48% were insufficiently active; and 9% were inactive. The following groups of women were more likely to be physically active: women with at least a high school education; women with perceived good health; women who knew people who exercise; and women who viewed the neighborhood as safe. These findings were statistically significant. Conclusions: Interventions that target urban African-American women must address the safety of the physical environment and personal and social environmental correlates of physical activity, and they should focus especially on inactive women who have less than a high school education or perceive themselves to be in poor health

Psychosocial Factors and Work-related Musculoskeletal Disorders among Southeastern Asian Female Workers Living in Korea

Objectives: A rapid increase in the population of migrant workers in Korea has brought new challenges regarding the possible effects of acculturation on health. The purpose of this study was to examine the influence of acculturation- and work-related psychosocial factors on work-related musculoskeletal disorders among migrant female workers living in Korea. Methods: A cross-sectional survey design was used. A translated, structured questionnaire was administrated to 156 southeastern Asian female full-time workers living in Korea. Results: About 35% of the participants experienced some type(s) of work-related musculoskeletal disorder(s), which were more prevalent in Vietnamese women than in Thai and Filipino women. Women who preferred to maintain their own heritage and to reject the host country heritage were at risk for work-related musculoskeletal disorders. Conclusion: Acculturation strategy and nationality were found to be significant factors associated with work-related musculoskeletal disorders. Health professionals need to accommodate acculturation contexts into risk assessment and intervention development for work-related musculoskeletal disorders separately for different nationalities
