Background

Individuals with respiratory conditions, such as asthma, are particularly susceptible to adverse health effects associated with higher levels of ambient air pollution and temperature. This study evaluates whether hourly levels of fine particulate matter (PM2.5) and dry bulb globe temperature (DBGT) are associated with the lung function of adult participants with asthma.

Methods and findings

Global positioning system (GPS) location, respiratory function (measured as forced expiratory volume at 1 second (FEV1)), and self-reports of asthma medication usage and symptoms were collected as part of the Exposure, Location, and Lung Function (ELF) study. Hourly ambient PM2.5 and DBGT exposures were estimated by integrating air quality and temperature public records with time-activity patterns using GPS coordinates for each participant (n = 35). The relationships between acute PM2.5, DBGT, rescue bronchodilator use, and lung function collected in one week periods and over two seasons (summer/winter) were analyzed by multivariate regression, using different exposure time frames.

In separate models, increasing levels in PM2.5, but not DBGT, were associated with rescue bronchodilator use. Conversely DBGT, but not PM2.5, had a significant association with FEV1. When DBGT and PM2.5 exposures were placed in the same model, the strongest association between cumulative PM2.5 exposures and the use of rescue bronchodilator was identified at the 0–24 hours (OR = 1.030; 95% CI = 1.012–1.049; p-value = 0.001) and 0–48 hours (OR = 1.030; 95% CI = 1.013–1.057; p-value = 0.001) prior to lung function measure. Conversely, DBGT exposure at 0 hours (β = 3.257; SE = 0.879; p-value>0.001) and 0–6 hours (β = 2.885; SE = 0.903; p-value = 0.001) hours before a reading were associated with FEV1. No significant interactions between DBGT and PM2.5 were observed for rescue bronchodilator use or FEV1.

Conclusions

Short-term increases in PM2.5 were associated with increased rescue bronchodilator use, while DBGT was associated with higher lung function (i.e. FEV1). Further studies are needed to continue to elucidate the mechanisms of acute exposure to PM2.5 and DBGT on lung function in asthmatics.

Authors: Mewes Janne C. , Lindenberg Melanie , Vrijhoef Hubertus J. M.
Published: June 2022

Objective

To assess the cost-effectiveness of preterm preeclampsia (PE) screening versus routine screening based on maternal characteristics in Germany and Switzerland.

Methods

A health economic model was used to analyse the cost-effectiveness of PE screening versus routine screening based on maternal characteristics. The analysis was conducted from the healthcare perspective with a time horizon of one year from the start of pregnancy. The main outcome measures were incremental health care costs and incremental costs per PE case averted.

Results

The incremental health care costs for PE screening versus routine screening per woman were €14 in Germany, and -CHF42 in Switzerland, the latter representing cost savings. In Germany, the incremental costs per PE case averted were €3,795. In Switzerland, PE screening was dominant. The most influential parameter in the one-way sensitivity analysis was the cost of PE screening (Germany) and the probability of preterm PE in routine screening (Switzerland). In Germany, at a willingness-to-pay for one PE case avoided of €4,200, PE screening had a probability of more than 50% of being cost-effective compared to routine screening. In Switzerland, at a willingness-to-pay of CHF0, PE screening had a 78% probability of being the most cost-effective screening strategy.

Conclusion

For Switzerland, PE screening is expected to be cost saving in comparison to routine screening. For Germany, the additional health care costs per woman were expected to be €14. Future cost-effectiveness studies should be conducted with a longer time horizon.

Published: June 2022

The interference control measured in the Emotional Stroop Task is the phenomenon that gives us an insight into mechanisms of emotion-cognition interactions. Especially the role of dimensions of affect can be easily studied with this paradigm. In the current study, we were interested in the role of the complexity of emotional stimuli (origin). We also aimed at searching for activation-like factors that impair (arousal) or improve (subjective significance) the effectiveness of cognitive control. We have used an orthogonal manipulation of all the above dimensions in words. We expected to find the contrastive effects of arousal and subjective significance on reaction times and Event Related Potential’s amplitudes. On a behavioural level, we observed the reduction of reaction times with increasing subjective significance of stimuli and reflective origin. We also found a correlation between subjective significance and reduction of amplitude polarisation in the N450 component associated with cognitive control execution effort. This experiment shows that subjective significance has an improving role for cognitive control effectiveness, even when valence, arousal and origin levels are controlled. This guides us to conclude that external stimuli may drive not only disruption of control but also its improvement.

Published: June 2022

Background

Southern China is at risk for arborvirus disease transmission, including Zika virus and dengue. Patients often present to clinical care with non-specific acute febrile illnesses (AFI). To better describe the etiology of AFI, we implemented a two-year AFI surveillance project at five sentinel hospitals in Yunnan and Guangdong Provinces.

Methods

Between June 2017 and August 2019, we enrolled patients between 2 and 65 years of age presenting at one sentinel hospital in Mengla County, Yunnan, and four in Jiangmen City, Guangdong, with symptoms of AFI (acute onset of fever ≥ 37.5°C within the past 7 days) without respiratory symptoms or diarrhea. Demographic, epidemiologic, and clinical information was obtained and entered into a web-based AFI surveillance database. A custom TaqMan Array card (TAC) was used to test patients’ whole blood specimens for 27 different pathogens using real-time polymerase chain reaction assays.

Results

During the two-year project period, 836 patients were enrolled; 443 patients from Mengla County and 393 patients from Jiangmen City. The median age was 33 years [range: 2–65], and most were hospitalized [641, 77%]. Of 796 patients with valid TAC results, 341 (43%) were positive for at least one of the 10 unique pathogens detected. This included 205 (26%) patients positive for dengue virus, 60 (8%) for Orientia tsutsugamushi, and 42 (5%) for Coxiella burnetii. Ten patients (1%) in Jiangmen City tested positive for malaria, 8 of whom reported recent travel outside of China. TAC results were negative for 455 (57%) patients. None of the patients had a positive TAC detection for Zika virus.

Conclusions

The project detected variability in the etiology of AFI in Southern China and highlighted the importance of differential diagnosis. Dengue, O. tsutsugamushi, and C. burnetii were the most frequently identified pathogens among enrolled AFI patients. As a non-notifiable disease, the frequent detection of C. burnetii is noteworthy and warrants additional investigation. The project provided a framework for routine surveillance for persons presenting with AFI.

Hepatitis C virus (HCV) is highly diverse and grouped into eight genotypes (gts). Infectious cell culture models are limited to a few subtypes and isolates, hampering the development of prophylactic vaccines. A consensus gt1b genome (termed GLT1) was generated from an HCV infected liver-transplanted patient. GLT1 replicated to an outstanding efficiency in Huh7 cells upon SEC14L2 expression, by use of replication enhancing mutations or with a previously developed inhibitor-based regimen. RNA replication levels almost reached JFH-1, but full-length genomes failed to produce detectable amounts of infectious virus. Long-term passaging led to the adaptation of a genome carrying 21 mutations and concomitant production of high levels of transmissible infectivity (GLT1cc). During the adaptation, GLT1 spread in the culture even in absence of detectable amounts of free virus, likely due to cell-to-cell transmission, which appeared to substantially contribute to spreading of other isolates as well. Mechanistically, genome replication and particle production efficiency were enhanced by adaptation, while cell entry competence of HCV pseudoparticles was not affected. Furthermore, GLT1cc retained the ability to replicate in human liver chimeric mice, which was critically dependent on a mutation in domain 3 of nonstructural protein NS5A. Over the course of infection, only one mutation in the surface glycoprotein E2 consistently reverted to wildtype, facilitating assembly in cell culture but potentially affecting CD81 interaction in vivo.

Overall, GLT1cc is an efficient gt1b infectious cell culture model, paving the road to a rationale-based establishment of new infectious HCV isolates and represents an important novel tool for the development of prophylactic HCV vaccines.

Published: June 2022

In this study, we derived the calculating formula for the standard sediment delivery rate (SDR) of forest watersheds by comparing and analyzing the potential quantity soil erosion using the universal soil loss equation (USLE) and the actual measurement based on the dredging data of check dams. In addition, by extracting forest watersheds in Gyeongsangbuk-do using GIS and applying them to it, we investigated the usability as basic data for the establishment of a fundamental construction plan for check dams in Gyeongsangbuk-do. As a result, the sediment delivery rate was high in small watersheds about 0.1㎢ compared to the predicted amount, but rapidly decreased in large watersheds of 1㎢ or more. Based on this, we figured out that the calculation formula for the standard sediment delivery rate of forest watersheds is SDR=0.2021×Area-0.712. Furthermore, after calculating the potential soil erosion quantity of forest watersheds in Gyeongsangbuk-do using USLE, it was estimated that a total of 9,897,192ton/year of sediment yields can be produced annually. Therefore, additional 2,743 check dams per year are required in order to control potential soil erosion of the forest watersheds in Gyeongsangbuk-do.

Authors:   Crisis and Emergency Management: Theory and Praxis, Choi Jung Yoon , Yoo Doo Ho
Published: June 2022

This research begins with the idea that the workplace plays a significant role in occupational safety and accident management. Government programs to address safety events and disasters have recently included the science and technology of the fourth industrial revolution. As a result, the purpose of this study is to investigate the experimental impact of these policies and responses to the fourth industrial revolution on workplace safety management. According to the research, it was discovered that the larger the policy influence, the better the workplace safety management. The interaction between policy impact and the response to the 4th industrial revolution was investigated, and it was found that the response to the 4th industrial revolution had a positive effect that reinforced the good impact of government policies on workplace safety management. Therefore, the government should develop policies to notice and respond to workplace safety incidents on a daily basis. We are also drafting policies so that workplaces can conduct their own safety management based on the characteristics of employees and organizations, as well as safety management techniques that combine technologies from the 4th industrial revolution.

The purpose of this study is to investigate how such factors as demography, community resilience and individual resilience of peoples living in Seoul, Incheon, and Gyeonggi-do Province affect the COVID-19 prevention behavior. The results of the analysis are as follows. First, in model 1 of hierarchical regression analysis, women, adults in their 40s and 50s, and citizens with the average monthly family income of more than 5 million won were appeared to enhance COVID-19 prevention behavior. Second, factors of community resilience were put into model 2. Coping with the crisis were shown to have positive effects on COVID-19 prevention behavior, but leadership has a negative impact, and social relationship were not statistically significant. Third, factors of individual resilience were put into model 3. The control ability, empathy and gratitude were appeared to have positive effects on COVID-19 prevention behavior, but satisfaction of life has a negative impact, and relational ability were not statistically significant. Collectively, it was confirmed that control ability is the most important factor in the prevention behavior of COVID-19.

Published: June 2022

A severe rain storm that occurred on July 16, 2017, caused flooding of paddy fields and rural houses south of Osong Biovalley. To analyze the flood event that occurred in the Cheongju area and to verify its effects on the Osong area, rainfall frequency analysis was evaluated based on the observed hydrological data. The recurrence frequency of flood events was estimated through rainfall frequency analysis, and the effect of flood events on the estimation of probable rainfall was confirmed. The GATE2012 flood simulation program was used to analyze the flood-damaged area. The program simulation was performed by dividing it into the case where the inflow of the generated discharge within the study area was not reflected and the case where it was reflected. In the case of not reflecting the inflow of the generated discharge, it was divided into the non-operational and normal operation of the pumping and drainage station, and in the case of consideration, the generated discharge was changed and the inundation analysis was performed by classifying it into nine cases. Through this study, it is to improve the reliability of the analysis of flood damage in paddy fields during floods and to contribute to the establishment of a flood prevention plan.

Published: June 2022

Debris flow transports lots of sediments downstream that cause damage to human lives and properties. The accurate estimation of the debris flow hazard zone is a critical factor of the successful early-warning and evacuation for reducing the debris flow risk. Korea Forest Service has developed a debris flow hazard map using Random Walk Model (RWM). Meanwhile, because check dams in forest watersheds capture discharged debris, the effect of check dams should be considered for mapping the debris flow hazard zone. This study analyzed the effect of check dams on debris flow discharge using RWM with the check dam module. As a result, RWM seems to simulate the sediment capture by check dams. However, the total deposit areas were not significantly different despite the effect of check dams because of input parameters and the flow direction calculation algorithm of RWM. Further studies on appropriate spatial resolution and initial sediment volume should be conducted to improve the debris flow hazard map.

Published: June 2022

Since many people died of thermal disease in 2012 and 2018, the heatwave in Korea has been considered one of the serious disasters, which has led to a significant increase in research on disasters caused by heatwave. However, most previous studies have mainly focused on the relative vulnerabilities of demographic factors such as regional size or gender, age, and occupation. According to previous studies by other countries suffering from heatwave, the causes of heatwave disasters include not only demographic backgrounds but also the role of surrounding societies such as public services. This study found that 11 influencing variables showed acceptable correlation with heatwave victims, and five pairs of contrast areas were selected. Subsequently, public functions were analyzed in the selected contrast regions; however, in spite of concerns over the heatwave, the heatwave shelter in this area has not been well promoted or operated.
A Rare Case Report of Sirenomelia
Authors: Pramod Kumar Sahu
Published: June 2022

Sirenomelia, which is also known as mermaid syndrome, is an extremely rare congenital developmental disorder characterized by anomalies of the lower spine and the lower limbs. Affected infants are born with partial or complete fusion of the legs. Additional malformations may also occur including genitourinary abnormalities, gastrointestinal abnormalities, anomalies of the lumbar-sacral spine and pelvis and absence or underdevelopment (agenesis) of one or both kidneys. Affected infants may have one foot, no feet or both feet, which may be rotated externally. The tailbone is usually absent, and the sacrum is partially or completely absent as well. Additional conditions may occur with sirenomelia including imperforate anus, spina bifida, and heart (cardiac) malformations. The incidence of sirenomelia is 8-1 case/100000[1] births with male to female ratio being 3:1.[2] Sirenomelia has no definite cause, almost all cases occur without any reason.

Previously, some literatures mentioned that sirenomelia is the severe form of caudal regression syndrome and has many developmental disorders. Recently much literature mentioned sirenomelia is similar but a different disorder. NORD has a different report on caudal regression syndrome.

The influence of pH, treatment time and resin concentration on the adsorption of metal ions from industrial wastewater was investigated. It was found that the obtained TTA resin effectively removes heavy metal ions in the following order: Fe2+> Cu2+> Zn2+> Cd2+> Pb2+.
Preoperative Evaluation of Non-Mass-Like Enhancement on Magnetic Resonance Imaging for Measuring Tumor Extent and Affecting Surgical Margin Status in Breast Cancer Patients
Authors: Park Seon Min , Kim Eun Young , Park Yong Lai , Park Chan Heun
Published: June 2022

Purpose: This study investigated the correlation between non-mass-like enhancement (NME) observed on preoperative breast magnetic resonance imaging (MRI) and the actual pathological size of breast cancer. We further examined the effect of NME on the positive resection margins during partial mastectomy.Methods: We retrospectively collected data from breast cancer patients who underwent surgery between January 2018 and September 2020. Patients were divided into two groups based on their MRI findings: NME and no-NME (mass-like lesion only) groups. The medical records, including MRI findings and clinicopathological information of patients, were collected retrospectively, and correlations with pathologic results were analyzed. Propensity score matching was applied to develop comparable cohorts of the NME group and no-NME group.Results: This study included a total of 317 patients, with 66 and 251 patients in the NME and no-NME groups, respectively. The mean pathologic size of invasive lesion was significantly smaller than the mean lesion size in the NME group (1.55±1.39 cm vs. 3.45±1.81 cm, p<0.001). The mean pathologic size of ductal carcinoma in situ (DCIS) lesions was larger than that in the NME group but without statistical significance (3.91±2.67 cm vs. 3.50±1.79 cm, p=0.326). In the NME group, NME estimated DCIS size to within 1 cm in 20 patients (30.3%) and overestimated invasive lesion size by more than 1 cm in 31 patients (46.9%). NME (vs. no-NME; odds ratio [OR], 2.967; 95% confidence interval [CI], 0.878-10.025) showed a tendency to predict positive resection margins, but this was not statistically significant (p=0.080).Conclusion: NME findings on MRI showed a similar extent of DCIS lesions. NME findings on preoperative MRI should be considered an important factor for measuring the extent of tumors, especially in DCIS patients.

Published: June 2022

Purpose: The standard care for patients with ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) is a total mastectomy (TM); however, there is growing interest in repeating BCS for IBTR.Methods: We retrospectively analyzed patients with IBTR who underwent initial BCS for breast cancer at our institution between January 2000 and December 2018. The Kaplan-Meier method was used to compare survival rates between the standard BCS-TM treatment group and the repeat-BCS group.Results: We enrolled 209 IBTR patients with a median follow-up of 102.3 months. No significant differences were observed in overall survival (10 years: 87.3% vs. 78.8%; hazard ratio [HR], 1.11; 95% confidence interval [CI], 0.44-2.81; p=0.821), distant metastasis free survival (10 years: 73.9% vs. 77.7%; HR, 0.80; 95% CI, 0.37-1.72; p=0.727) and disease-free survival (10 years: 57.1% vs. 65.2%; HR, 0.63; 95% CI, 0.35-1.12; p=0.115) between two groups. Repeat-BCS group showed significantly poorer locoregional recurrence free survival rate than did the TM group (HR, 2.44; 95% CI, 1.06-5.56; p=0.029) but the significance was not shown after excluding ipsilateral breast tumor recurrence events.Conclusion: No significant differences were observed in survival outcomes and recurrence rates between patients with IBTR who underwent mastectomy or repeat BCS regardless of molecular subtype, except secondary IBTR rates.

Policies of quality and autonomy in times of economic crisis: Governing the sector of early childhood education and care
Authors: Kalogerakis Panagiotis , Tsatsaroni Anna
Published: June 2022

This study focuses on the debate surrounding global policies and practices related to the sector of Early Childhood Education and Care (ECEC), utilizing the Greek policy context as an example. Drawing on the critical education policy studies literature, this paper interrogates the complex concepts of quality and autonomy, which are core in the global agenda. We do this by exploring how the international and national austerity measures, imposed in many countries – and especially in Greece, marked by a devastating economic crisis in the last decade – have affected their re-interpretation and translation. Our empirical data suggest that municipal ECEC directors, interviewed in the context of our research, hold diverse views on quality, raising issues of inequality, limited participation and low attainment. The study generates reflections, suggesting that the idea of autonomy has been systematically associated with Greece’s economic struggles and therefore understood and re-interpreted by the participants in a constrained way that limits their action. The way these notions are re-contextualized at the municipal level, and the consequences for ECEC provision, pose as key issues of this research.

Days Sales of Inventory (DSI), Days Sales Outstanding (DSO), Days Payable Outstanding (DPO) and Cash Conversion Cycle (CCC) were used as WCM metrics. The study was based on micro-data for 39 consumer goods companies with period from 2015 – 2019. By using multiple regression and correlations analysis, the study shows that extending DSO and DPO had a profitable impact on ROA and extending the DSI and CCC had an adverse impact on ROA in consumer goods companies. Keywords : consumer goods industry, profitability, working capital management
Paradygmaty metafilozofii – historia i współczesność
Authors: Wawrzynowicz Andrzej
Published: June 2022

Metaphilosophy as a research discipline is concerned with the overall metatheoretical reflection of philosophy on its own subject matter, assumptions, methodology, and goals guiding this form of human intellectual activity. The aim of this article is to present a cross-sectional analysis of the main stages in the historical development of this discipline, and offer a general characterization of the current state of research. The means to achieving this goal of study is a confrontation between two partly competitive and partly complementary paradigmatic approaches to metaphilosophical reflection which currently determine a relatively wide range of interests in this theoretically promising and heuristically fertile field of philosophical analysis.

Analysis of pilots’ EEG map in take-off and landing tasks
Authors: Ji Li , Zhang Chen , Li Haiwei , Zhang Ningning , Zheng Peng , Guo Changhao , Zhang Yong , Tang Xiaoyu
Published: June 2022

The take-off and landing phases are considered the critical stages of aircraft flight. To ensure flight efficiency and safety in the critical stages, this research proposes a method for analyzing and monitoring pilot flight status by β-wave. The focus of the study is β potential changes on the EEG map. First, the proportion of β-wave in the electroencephalogram (EEG) of pilots during take-off and landing increases significantly. Second, the EEG map accurately and intuitively reflects the spatial distribution of potential changes in brain regions. Finally, correlation and machine learning are used for further research of β-wave. The conclusions show that the significant changes in the β-wave caused by take-off and landing can be seen in the EEG map to identify and adjust the pilot’s state. Therefore, this research provides more accurate and effective reference information (like the EEG map, correlation and machine learning) for efficient and safe flight training in the critical stages.

A Defence of Robust Idealism in Political Philosophy
Authors: Bertea Stefano
Published: June 2022

In this contribution, I defend a robust model of political idealism, making the case for such an approach to both the theory and practice of politics. On this view, not only in framing a political philosophy but also in putting forward policy proposals and institutional designs, we need not think about feasibility as an overriding, make-or-break criterion for evaluating the soundness of that theory or proposal, neither of which loses its point simply because it is deemed to be unlikely to be implemented. Feasibility, in other terms, cannot be taken as the only standard, or even as the main standard, on which basis to assess the practical worth of a political strategy.

We establish a set of new su˚cient conditions on the existence of at least one positive periodic solution by using the continuation theorem of coincidence degree theory. Our results not only provide a new approach but also generalize previous results. An example with graphical representations are presented to illustrate the results.
WITNESS PROTECTION PROGRAMME: THE VIEWS OF WITNESSES AND STAFF MEMBERS ON HOW CHILDREN ARE AFFECTED BY THE ADMISSION OF THEIR PARENTS INTO THE PROGRAMME
Authors: Mphaphuli Lucy Nthepa
Published: June 2022

Children, although innocent, are often admitted into the witness protection programme with their parents and, as a result, they experience isolation and social uprooting. This qualitative study aimed to describe the views of witnesses and staff members on how children are affected by the admission of their parents into the witness protection programme in South Africa. The ecological systems perspective, which recognises the impact of the environment on human functioning, and the person-in-environment perspective provided the theoretical framework. The findings confirmed the hardships of children in coping with the admission of their parents into the witness protection programme.

Features of the Organization of Creative Activity in History Lessons at School in Grades 6–7
Authors:   Blagoveshchensk State Pedagogical University, Buyarov Dmitry V. , Krestinina Yana S. ,   Chigirinskaya Secondary School
Published: June 2022

The article is devoted to the analysis of the problem of the organization of creative activity in history lessons in secondary school. Currently, the relevance of this methodology has increased significantly, which is associated with changes in standards in the field of education. Creative activity at school contributes to the development of personal qualities of schoolchildren in unity with professional skills of creative and inventive activity. The systematic work of a history teacher to develop the creative abilities of middle school students orients them to show interest in independent intellectual activity, the need for their own research of historical processes and phenomena, the desire to master intellectual skills and abilities, the need for active creative activity. The purpose of the article is to identify and characterize the features of the organization of creative activity in history lessons at school in grades 6-7. At the same time, the choice of age is due to the fact that, on the one hand, students already have a primary base of necessary skills and abilities, and on the other hand, they are still distinguished by sincere interest and willingness to realize their undiscovered creative potential. Methodology. The study was conducted on the basis of studying the modern educational environment. In the course of practical activity and theoretical generalization, an appeal was made to the technology of creative developing learning, to the method of artistic performance, which allows organizing joint activities of teachers and students on the basis of mastering artistic means of expressing their aesthetic understanding and attitude to historical reality. At the same time, creativity is considered in inseparable connection with educational and research activities. In conclusion, it is concluded that the implementation of the lesson with the use of creative activity is carried out through the use of various forms of creative activity, including such as problem-based learning, project activities, conducting non-traditional lessons.
