Intervention measures have been implemented worldwide to reduce the spread of the COVID-19 outbreak. The COVID-19 outbreak has occured in several waves of infection, so this paper is divided into three groups, namely those countries who have passed the pandemic period, those countries who are still experiencing a single-wave pandemic, and those countries who are experiencing a multi-wave pandemic. The purpose of this study is to develop a multi-wave Richards model with several changepoint detection methods so as to obtain more accurate prediction results, especially for the multi-wave case. We investigated epidemiological trends in different countries from January 2020 to October 2021 to determine the temporal changes during the epidemic with respect to the intervention strategy used. In this article, we adjust the daily cumulative epidemiological data for COVID-19 using the logistic growth model and the multi-wave Richards curve development model. The changepoint detection methods used include the interpolation method, the Pruned Exact Linear Time (PELT) method, and the Binary Segmentation (BS) method. The results of the analysis using 9 countries show that the Richards model development can be used to analyze multi-wave data using changepoint detection so that the initial data used for prediction on the last wave can be determined precisely. The changepoint used is the coincident changepoint generated by the PELT and BS methods. The interpolation method is only used to find out how many pandemic waves have occurred in given a country. Several waves have been identified and can better describe the data. Our results can find the peak of the pandemic and when it will end in each country, both for a single-wave pandemic and a multi-wave pandemic.

Objective: Community pharmacists are frontline health care providers, but have been considered as underutilized professionals on a daily basis. The purpose of this scoping review was to identify information about the impact of the COVID-19 pandemic on community pharmacy services and to evaluate new services that could be applicable. Methods: We searched MEDLINE and EMBASE for studies published up to January 10, 2020. Search terms consisted of keywords relevant to this review, including "COVID-19", "community pharmacy", and "community pharmacist". This review targeted studies of pharmacist services provided by community pharmacies in OECD member countries during the COVID-19 pandemic period. Results: Twenty-seven studies were included in this review. Changes in community pharmacist services due to the COVID-19 pandemic were broadly classified into four categories. First, as the face-to-face services became challenging, various non-face-to-face services were being tried. Second, community pharmacists directly participated in the services to prevent the spread of COVID-19. Third, community pharmacists made efforts to support continuity of care for patients who experienced difficulties due to the reduced professional care as health and medical resources are concentrated in response to COVID-19. Fourth, community pharmacist services were emerging, targeting patients suffering from greater health inequality during the pandemic. Patients expressed high demand and satisfaction for the service of the community pharmacist, and pharmacists reported self-efficacy and professional pride. Conclusion: This study demonstrated that in the era of the COVID-19 pandemic, various community pharmacist services have been tried and received positive evaluations from patients in several OECD countries.

본 논문의 목적은 COVID-19의 최근 주요 연구 동향을 파악하는데 있다. 이에 Elsevier에서 제공하는 해외 학술 DB인 SCOPUS를 활용하여 최근 3년간(2020~2022) COVID-19의 연구 동향을 파악하고자 한다. 빈도 분석 결과, covid가 7,248건, pandemic이 4,974건, study가 3,313건, research가 2,137건, crisis가 1,777건 순으로 그 중요도가 나타났다. 트렌드 분석결과, covid와 pandemic은 꾸준하게 연구가 진행되고 있으나, study, research, crisis는 최근 들어 연구가 다소 감소하고 있는 것으로 나타났다. LDA 토픽 모델링 분석 결과, 중요한 토픽은 'covid19, pandemic' 인 것으로 나타났다. 이는 COVID-19에 대한 연구가 일상생활뿐만이 아니라 기업이나 조직에서도 필요하기 때문에 의학 이외의 다른 학문 분야에서도 중요하다는 것을 보여준다. 특히 COVID-19가 그 어느 때보다도 중요해지는 상황에서 COVID-19의 연구가 미치는 영향 및 파급효과에 관한 관심이 지속적으로 이루어질 것으로 보인다.

Objective : Hospital workers' mental health has deteriorated because of the ongoing COVID-19 pandemic. The purpose of this study was to investigate the impact of the prolonged COVID-19 pandemic on the mental health of hospital workers and its determinants. Methods : Two surveys were conducted among employees working in a hospital that received COVID-19 patients from the early phase of the pandemic in South Korea. Data on demographics, perceived threat, workplace evaluation, resilience, and mental health status were collected using the Korean General Health Questionnaire-20 in the initial phase (February 2020) and during the third wave of COVID-19 (December 2020) for 467 and 545 workers, respectively. The mental health of hospital workers in the two phases was compared, and the risk and protective factors during the third wave were investigated. Results : The proportion of patients in the psychiatric high-risk group increased from 2.8% in the initial phase to 11.4% during the third wave. The perceived threat, workplace evaluation, and resilience of respondents deteriorated. Risk factors for mental health during the third wave included the perceived threat items of job stress, loss of control, and considering resignation. Protective factors included presence of children, workplace satisfaction, and hardiness in resilience. Conclusion : Hospital workers' mental health deteriorated as the pandemic progressed. General stress and tension such as job stress, loss of control, considering resignation rather than COVID-19-specific stress had negative effects on mental health of hospital workers. Therefore, care for work stress itself can be helpful to maintain the mental health of hospital workers. Also, governance to improve workplace satisfaction or hardiness in resilience can be a potential protective factor for hospital workers' mental health during the prolonged pandemic.

Objectives: This study explored the effect of the coronavirus disease 2019 (COVID-19) pandemic on psychosocial stress in prime working-age individuals in Korea, focusing on gender inequalities. We hypothesized that the impact of COVID-19 on mental health would differ by age and gender, with younger women potentially demonstrating heightened vulnerability relative to men. Methods: The study involved data from the Korea Community Health Survey and included 319 592 adults aged 30 years to 49 years. We employed log-binomial regression analysis, controlling for variables including age, education, employment status, marital status, and the presence of children. The study period included 3 phases: the period prior to the COVID-19 outbreak (pre-COVID-19), the early pandemic, and the period following the introduction of vaccinations (post-vaccination). Results: The findings indicated that women were at a heightened risk of psychosocial stress during the early pandemic (relative risk [RR], 1.01; 95% confidence interval [CI], 0.98 to 1.05) and post-vaccination period (RR, 1.07; 95% CI, 1.04 to 1.10) compared to men. This pattern was prominent in urban women aged 30-34 years (pre-COVID-19: RR, 1.06; 95% CI, 1.02 to 1.10; early pandemic: RR, 1.16; 95% CI, 1.08 to 1.25; post-vaccination period, RR, 1.22; 95% CI, 1.14 to 1.31). Conclusions: The COVID-19 pandemic has exerted unequal impacts on psychosocial stress among prime working-age individuals in Korea, with women, particularly those in urban areas, experiencing a heightened risk. The findings highlight the importance of addressing gender-specific needs and implementing appropriate interventions to mitigate the psychosocial consequences of the pandemic.

Background: Starting from March 2020 until December 2021, different phases of Covid-19 pandemic have been identified in Italy, with several containing/lifting measures progressively enforced by the National government. In the present study, we investigate the change in occupational risk during the subsequent pandemic phases and we propose an estimate of the incidence of the cases by economic sector, based on the analysis of insurance claims for compensation for Covid-19. Methods: Covid-19 epidemiological data available for the general population and injury claims of workers covered by the Italian public insurance system in 2020-2021 were analyzed. Monthly Incidence Rate of Covid-19 compensation claims per 100,000 workers (MIRw) was calculated by the economic sector and compared with the same indicator for general population in different pandemic periods. Results: The distribution of Covid-19 MIRw by sector significantly changed during the pandemic related to both the strength of different waves and the mitigation/lifting strategies enforced. The level of occupational fraction was very high at the beginning phase of the pandemic, decreasing to 5% at the end of 2021. Healthcare and related services were continuously hit but the incidence was significantly decreasing in 2021 in all sectors, except for postal and courier activities in transportation and storage enterprises. Conclusion: The analysis of compensation claim data allowed to identify time trends for infection risk in different working sectors. The claim rates were highest for human health and social work activities but the distribution of risk among sectors was clearly influenced by the different stages of the pandemic.

본 연구는 통합적 문헌고찰을 통해 COVID-19 팬데믹 상황에서의 임신부 스트레스의 특징을 파악하고자 하였다. 자료수집은 2020년부터 출간된 문헌 중 영어 또는 한글로 발표된 논문들을 대상으로 2023년 5월 1일부터 2023년 8월 10일까지 수행하였다. 문헌검색은 PubMed, Embase, Cochrane library, CINAHL의 국외 검색엔진과 RISS, KISS, 국회도서관의 국내 검색엔진을 사용하였는데, 'pregnan*', 'maternity', 'COVID', 'corona', 'pandemic', 'infection', 'stress'코로나, '팬데믹', '감염', 및 '스트레스'의 검색어를 조합하여 실시하였고, 질평가를 거쳐 최종 13편의 문헌이 선정되었다. COVID-19 팬데믹 상황에서 임신부 스트레스 정도는 대체로 증가하였으며, 임신부 스트레스 주요 요인으로는 임신부의 의학적 상태, 정신심리적 요인, 사회경제적 요인이 있었다. COVID-19 팬데믹 상황 하에서 임신부를 대상으로 이루어진 스트레스 감소 중재는 비대면 교육 및 훈련이 효과적인 것으로 나타났다. 본 연구결과를 바탕으로 신종 감염재난 상황을 대비할 수 있는 스트레스 감소 프로그램 개발의 토대가 될 수 있을 것이라 사료된다.

COVID-19 팬데믹은 정부의 예방 및 통제 조치, 사람들의 위험 인식의 변화, 그리고 생활 방식의 변화를 통해 상당한 사회적 변화를 가져왔다. 특히, 정부의 방역정책과 도시공간의 잠재적 감염 위험에 대한 우려는 교통수단과 도시공간에 대한 선호를 크게 변화시켰다. 이러한 변화는 COVID-19 팬데믹이후에도 도시 공간에 지속적인 영향을 미치거나 새로운 형태로 변화할 수 있다. 따라서 본 연구는 코로나19 범유행에 따른 도시민의 이동수단 선호와 도시공간 이용 변화를 분석하여 도시공간이 현재와 미래의 감염병에 적응할 수 있는 회복탄력성과 잠재력을 탐색하고자 한다. 본 고는 이동 수단과 도시 공간에 대한 전반적인 선호도가 팬데믹 이전, 팬데믹 중, 팬데믹 종료에 따라 유의미하게 차이가 있다는 것을 확인하였다. 팬데믹 기간 동안 안전하다고 인식되는 개인 소유 차량과 녹지 공간을 제외하고는 전반적인 이동수단과 도시 공간에 대한 선호도가 감소하였다. 특히, 이동수단과 도시 공간에 대한 유행 중 선호도는 팬데믹 전에 비해 5배 가량 낮게 나타났다. 팬데믹 당시 긍정적으로 인식되었던 녹지 공간과 의료시설이 팬데믹 이전 선호도 수준으로 돌아올 것으로 예상되나, 다른 도시 공간 요소들은 뉴노멀을 맞이한 것으로 보인다. 본 결과는 코로나19 팬데믹이 도시민의 이동 수단과 도시 공간 선호에 큰 영향을 미쳤음을 시사한다.
