ObjectivesThis study evaluated the response in Daegu, Korea to the first wave of the coronavirus disease 2019 (COVID-19) pandemic according to a public health emergency response model.MethodsAfter an examination of the official data reported by the city of Daegu and the Korea Centers for Disease Control and Prevention, as well as a literature review and advisory meetings, we chose a response model. Daegu’s responses were organized into 4 phases and evaluated by applying the response model.ResultsIn phase 1, efforts were made to block further transmission of the virus through preemptive testing of a religious group. In phase 2, efforts were concentrated on responding to mass infections in high-risk facilities. Phase 3 involved a transition from a high-intensity social distancing campaign to a citizen participation–based quarantine system. The evaluation using the response model revealed insufficient systematic preparation for a medical surge. In addition, an incorporated health-related management system and protection measures for responders were absent. Nevertheless, the city encouraged the participation of private hospitals and developed a severity classification system. Citizens also played active roles in the pandemic response by practicing social distancing.ConclusionsThis study employed the response model to evaluate the early response in Daegu to the COVID-19 pandemic and revealed areas in need of improvement or maintenance. Based on the study results, creation of a systematic model is necessary to prepare for and respond to future public health emergencies like the COVID-19 pandemic.  相似文献

Introduction and Aims. Cultural and biological particulars existing in East Asian countries are likely to mediate differences in the alcohol consumption experience. Despite this no research to date has directly explored the alcohol free association or expectancy of any East Asian nations. The current research aims to provide a set of South Korean alcohol expectancies. Design and Methods. Two hundred and thirty‐seven South Koreans participated in an alcohol free association test and completed a demographic survey. Results. The results both confirmed and contradicted areas of past alcohol expectancy research. There appears to be differences in associates with high probability of recall and alcohol expectancy, where negative, negative sedating and sedating expectancy categories were not found to be predictors of South Korean drinker level. Discussion and Conclusion. The results suggest that South Koreans have a more even level of negative expectancy across all drinker categories, possibly due to a combination of linguistic, cultural and biological difference found among this population. The results provide a list of South Korean alcohol free association norms for future alcohol research in the region, with the results also underlining the need for alcohol free association tests among East Asian nations.[Mahoney BJ, Graham D, Cottrell D, Kim K‐Y.

公共服务体系是现代文明社会的基本标志,也是现代社会稳定发展的基础,公共经济学和欧美国家的发展经验已经证明了这一点。韩国是从上世纪80年代取得“汉江奇迹”后,在经济增长成就和产生的社会问题的双重推动下,开始了以奉侍型政府、国民中心等为目标的管理改革,并逐步建立起比较完善的公共服务体系。中国在进入新世纪后提出建设服务型政府,开始建立和完善公共服务体系。研究表明,在建立公共服务型政府的改革中,两国在价值理念、改革目标、改革路径和举措等方面都有许多相同相似的方面,但也存在差异性。总体上,韩国在建立公共服务型政府,提高公共服务质量等方面要比中国先行一步,有许多值得中国政府学习和借鉴的地方。  相似文献

Background

Biological measurements have been employed as useful biomarkers for exposure. Because of its property of reflecting toxicokinetic differences, however, within-subject variability leads to biased results in epidemiologic studies.

Method

We examined the variability of lead (Pb), mercury (Hg), and cadmium (Cd) levels in blood samples from 1429 participants among 1677 elderly individuals aged over 60 years who lived in an urban area from August 2008 to April 2015.

Results

The geometric means of blood Pb, Hg, Cd were 1.92 μg/dL, 2.48 μg/L, and 1.33 μg/L, and the intra-class correlations (ICCs) were 0.81, 0.71, and 0.83, respectively. The mean values of Pb and Hg levels in this study were lower than the results from single spot samples in other national biomonitoring surveys in Korea, with the exception of Cd was higher than those in other studies. Moreover, the predicted exceedances over the guidance levels for Pb, Hg, and Cd were 1.9%, 4.2%, and 0.3%, respectively.

Conclusion

Korean elderly were exposed to high levels of Pb, Hg and Cd. Especially, those who had high levels of Cd were continuously exposed to Cd during study period with the 6 collection intervals. Therefore, factors affecting environmental Cd exposure should be further studied in the future.  相似文献

The roles of social workers in hospitals have changed in accordance with the environmental changes in the healthcare system. Since 1958, hospital social workers have performed important roles in providing care services in South Korea. Providing psychosocial services was considered to be the most important for more than 30 years from the 1970s to the 1990s. The healthcare system has since undergone major environmental changes, yet there has been little study on the role of hospital social workers in South Korea. In order to address this research gap, this study aims to explore how the roles of hospital social workers have changed since the 2000s. We recruited 198 hospital social workers who were active members of the Korean Association of Medical Social Workers as study participants. The average age of participants was 35.36 years old (SD = 8.27), and they had an average of 8.24 years in hospital social work experience (SD = 6.35). The results indicated that the roles of financial support and community resource linkage, which were regarded to be relatively less important until the 1990s, were recognized as the most important. Given the role changes of hospital social workers in South Korea, implications are discussed.  相似文献

BackgroundThe Korea National Antimicrobial Use Analysis System (KONAS), a benchmarking system for antimicrobial use in hospitals, provides Korean Standardized Antimicrobial Administration Ratio (K-SAAR) for benchmarking. This article describes K-SAAR predictive models to enhance the understanding of K-SAAR, an important benchmarking strategy for antimicrobial usage in KONAS.MethodsWe obtained medical insurance claims data for all hospitalized patients aged ≥ 28 days in all secondary and tertiary care hospitals in South Korea (n = 347) from January 2019 to December 2019 from the Health Insurance Review & Assessment Service. Modeling was performed to derive a prediction value for antimicrobial use in each institution, which corresponded to the denominator value for calculating K-SAAR. The prediction values of antimicrobial use were modeled separately for each category, for all inpatients and adult patients (aged ≥ 15 years), using stepwise negative binomial regression.ResultsThe final models for each antimicrobial category were adjusted for different significant risk factors. In the K-SAAR models of all aged patients as well as adult patients, most antimicrobial categories included the number of hospital beds and the number of operations as significant factors, while some antimicrobial categories included mean age for inpatients, hospital type, and the number of patients transferred from other hospitals as significant factors.ConclusionWe developed a model to predict antimicrobial use rates in Korean hospitals, and the model was used as the denominator of the K-SAAR.  相似文献

The coronavirus disease 2019 (COVID-19) resulted in a marked decrease in the number of patient visits for acute myocardial infarction and delayed patient response and intervention in several countries. This study evaluated the effect of the COVID-19 pandemic on the number of patients, patient response time (pain-to-door), and intervention time (door-to-balloon) for patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI).Patients with STEMI or NSTEMI visiting a hospital in South Korea who underwent primary coronary intervention during the COVID-19 pandemic (January 29, 2020, to December 31, 2020) were compared with those in the equivalent period from 2018 to 2019. Patient response and intervention times were compared for the COVID-19 pandemic window (2020) and the equivalent period from 2018 to 2019.We observed no decrease in the number of patients with STEMI (P = .88) and NSTEMI (P = 1.00) during the COVID-19 pandemic compared to that in the previous years. Patient response times (STEMI: P = .39; NSTEMI: P = .59) during the overall COVID-19 pandemic period did not differ significantly. However, we identified a significant decrease in door-to-balloon time among patients with STEMI (14%; P < .01) during the early COVID-19 pandemic.We found that the number of patients with STEMI and NSTEMI was consistent during the COVID-19 pandemic and that no time delays in patient response and intervention occurred. However, the door-to-balloon time among patients with STEMI significantly reduced during the early COVID-19 pandemic, which could be attributed to decreased emergency care utilization during the early pandemic.  相似文献

ObjectivesThis study assessed the prevalence and changes of human immunodeficiency virus (HIV) knowledge and stigmatizing attitudes in 2006, 2008, and 2011.MethodsThree cross-sectional surveys were conducted in 2006, 2008, and 2011. A cross-sectional sample of high school students in Seoul, South Korea was targeted. A self-administered questionnaire measuring general and transmission and discriminatory attitudes was used.ResultsMisconceptions about casual contact were widespread, even though the proportion responding incorrectly decreased significantly over the 5-year period. The respondents in all surveys displayed a high level of discrimination against those with HIV/AIDS in some situations, particularly in the idea of HIV/AIDS making the respondent feel disgusted (63.3% in 2006, 57.5% in 2008, and 52.6% in 2011), avoiding sitting with people with HIV/AIDS (50.6% in 2006, 50.5% in 2008, and 48.5% in 2011), and blaming those with HIV for becoming infected (46.6% in 2006, 42.8% in 2008, and 43.0% in 2011). Even though respondents had a high level of stigmatizing attitudes, the survey showed that the stigma has declined over the 5-year period.ConclusionThe survey results showed that public health policy should recognize that HIV stigmatizing attitudes persist in Korea. This finding has implications for the development of intervention programs focusing on reducing the levels of discrimination.  相似文献
