Background. A third wave of COVID-19 infection is now sweeping across the globe. Severe injury of the epithelial barrier, caused by the action of respiratory viruses (including coronaviruses), facilitates the invasion of the respiratory tract with other germs, like viruses, fungy or bscteria. Methods. 92 inpatients with COVID-19 pneumonia and 68 inpatients with nosocomial pneumonia (NP) non COVID-19 were enrolled in our study. For microbiological assessment sputum samples were collected. Statistical analysis performed using the x2 test (Statistica software, version 7.0). Results. From the 92 COVID-19 patients 64 (69,2%) were dignosed with secondary nosocomial bacterial infection (SNBI). Overall ESKAPE agents, like K.pneumoniae, E.faecium, Acinetobacter spp. and Ps.aeruginosa were highly detected in SARS- CoV-2 group — 85,7%. in opposed to non COVID-19 group, bacterial agents isolated from the patients with SARS-CoV-2 SNBI manifested higher rate of antibiotical panresistance (p < 0,05). Conclusions. The study showed some etiological and antibiotic resistance differences of COVID-19 SNBI, compared to non SARS-CoV-2 NP and a higher rate of antibiotical panresistance in COVID-19 group. Thus, the empirical treatment in bacterial co-infections in SARS-CoV-2 patients requires proven argumentation and adjustment to antibiotic resistance data in each case separately.

Cephalosporins, and primarily ceftriaxone, were the main group of antibiotics used as monotherapy in case of community-acquired pneumonia of inpatient treatment. Macrolides and fluoroquinolones have been used predominantly in combination with cephalosporins (ceftriaxone, ceftazidime, cefuroxime, cefazolin) in patients with comorbidities. The selection of empirical antibacterial preparations was based on subjective, objective, laboratory and radiological data, as well as by analyzing epidemiological data and antibacterial resistance in hospital. The optimal strategy in the selection of antibiotics or their combinations is determined by covering spectrum of possible microbial agents, obtaining a synergistic antimicrobial effect and avoiding potential adverse reactions.

The term nontuberculous mycobacteria (NTM) includes different species of mycobacteria, other than Mycobacterium tuberculosis complex (M. bovis, M. africanum, M. microti, M. canetti, M. caprae, M. pinnipedii, M. suricatta, M. mungi) and other than those that cause leprosy (M. leprae, M. lepromatosis). The rate of lung infection with NTM increases with age and varies considerably in different countries. NTM are opportunistic pathogens that can cause the disease, especially in immunocompromised patients or in those with preexisting lung disease. The decision to initiate the treatment is based on an assessment of the potential risks and benefits, individually for each patient. The aim of the treatment is to liquidate/ improve the clinical and functional manifestations, to reduce the lung lesions and to restore work capacity. The treatment of patients with mycobacteriosis is a complex one (polychemotherapy, if necessary — surgical treatment etc.), long-term, under direct observation, administered in the hospital and/or at home. The treatment regimen is chosen depending on the species involved, radiological picture, comorbidities, drug sensitivity etc.

QT interval prolongation is a predictor of the life-threatening cardiac arrhythmias — polymorphic ventricular tachycardia (torsade de pointes). Long QT syndrome may be congenital or acquired. It is known that a wide range of both antiarrhythmic and non-cardiac medications might lead to QT interval prolongation. List of drugs that cause QT prolongation is constantly growing and being updated. The review contains current data on the clinical significance of the control of QT interval duration within drug therapy. Clinical conditions associated with an increased risk of QT interval prolongation are described. Drugs that can induce QT prolongation are also discussed.

The study aimed to examine the effect of prior knowledge, self-efficacy, emotional intelligence, learning behavior, and culture on the level of significance accounting understanding of Islamic banking students in Salatiga. This study uses primary data by providing questions in the form of questionnaires distributed to respondents who are students of the Islamic Banking Study Program, Faculty of Economics and Islamic Business, IAIN Salatiga. The sample was selected using the purposive sampling method. A total number of 180 questionnaires were sent out and 160 questionnaires can be processed. The data is processed by multiple linear regression analysis to prove the hypothesis. The results showed that partially the effect of prior knowledge has a significant effect on accounting understanding, although the four other variables, namely self-efficacy, emotional intelligence, learning behavior, and culture have no effect on the level of accounting understanding of Islamic banking students in other cities.

Backgrond: Despite global legislative and regulatory efforts to ensure sustainable food safety and security, mycotoxins remain a serious challenge in the supply of staple food commodities like maize and other grains in South Africa. Objectives: We reviewed mycotoxin contamination of maize, maize-associated food products, together with other cereals to emphasis the need for continuous monitoring and management in South Africa. Methods: A scoping review was conducted on mycotoxin contamination of maize, maize-related products, and other cereals, as well as associated health implications in South Africa. The review intended to identify relevant articles and reports from 1980 to 2020 based on Arksey and O’Malley guidelines. Results: Of the 103 articles/reports identified for the research questions “that define to what extend the South African population is exposed to mycotoxins, and why”, 31 (30 %) were eligible for this study. The most recurrent mycotoxins were fumonisins (FBs) and aflatoxins (AFs). The levels of FBs and AFs were as high as 140480 and 762 µg/kg, respectively. Conclusion: The FBs and AFs were the main mycotoxins in maize, other cereals, and related products. Therefore, adopting effective, sustainable, and scalable measures in limiting mycotoxin contamination is critical for the mitigation of food insecurity and the resulted health burden. Training farmers and other stakeholders on good hygiene and farming practices along the food chain is important.
Much Ado about Nothing?

Published: June 2021

This essay carefully examines the debate between Hegel and Wilhelm von Humboldt about the meaning of the Bhagavad Gîtâ, and more specifically about several verses in Gîtâ 6 regarding the radical emptying and purification of the mind. My aim is to propose a new and wider conversation, not possible in Hegel’s time but necessary in ours, between European scholars and peer Indian intellectuals in traditions familiar with the Gîtâ for centuries before any European knew of it at all. To exemplify this new work, I attend to the reading of the same Gîtâ 6 passage by the famed philosopher and theologian Madhusûdana Sarasvatî (ca. 1540–1640). In this way, the European inquiry into the status of Indian thought and religion ceases to be an exclusively European endeavor, becoming instead a beneficial and mutually corrective crosscultural and interreligious conversation about texts and history, philosophy and theology.
Link Travel Time Estimation in Double-Queue-Based Traffic Models
Authors: Yang Xia , Ma Rui , Yang Peng , Ban Xuegang Jeff
Published: June 2021

Double queue concept has gained its popularity in dynamic user equilibrium (DUE) modeling because it can properly model real traffic dynamics. While directly solving such double-queue-based DUE problems is extremely challenging, an approximation scheme called first-order approximation was proposed to simplify the link travel time estimation of DUE problems in a recent study without evaluating its properties and performance. This paper focuses on directly investigating the First-In-First-Out property and the performance of the first-order approximation in link travel time estimation by designing and modeling dynamic network loading (DNL) on single-line stretch networks. After model formulation, we analyze the First-In-First-Out (FIFO) property of the first-order approximation. Then a series of numerical experiments is conducted to demonstrate the FIFO property of the first-order approximation, and to compare its performance with those using the second-order approximation, a point queue model, and the cumulative inflow and exit flow curves. The numerical results show that the first-order approximation does not guarantee FIFO and also suggest that the second-order approximation is recommended especially when the link exit flow is increasing. The study provides guidance for further study on proposing new methods to better estimate link travel times.
Decision Making on Government Subsidy for Highway Public-Private Partnership Projects in China Using an Iteration Game Model

Published: June 2021

Government subsidy is an important responsibility of fiscal expenditure in public-private partnership (PPP) projects. However, an improper subsidy strategy may cause over-compensation or under-compensation. In this research, an iteration game model combining game theory and real option is established to describe the periodic decision-making process. The strategy game model is applied to characterize the behavioral interactions between stakeholders, and the real option theory is used to predict the project performance under the influence of their decisions. Besides, two new indicators, the efficiency of fund (SE) and the total extra cost paid by the private sector (ME), are proposed to evaluate the extra project revenue caused by each unit of the subsidy and the incentive effects of the subsidy. Consequently, the preliminary results indicate that a periodic and iterative negotiations regarding the subsidy will effectively improve the efficiency of fund compared to the traditional way. The results also show that it is important for the public sector to give incentives, encouraging the private sector to make more efforts on the project, rather than merely providing fund support. Further study will focus on more detailed and complicated behaviors of stakeholders based on the model proposed in this paper.
Understanding Human Mobility Within Metro Networks – Flow Distribution and Community Detection
Authors: Gan Zuoxian , Liang Jing
Published: June 2021

In this paper, smart card data collected from the Nanjing Metro over 2-hour time periods are used to characterize within- and between-day human mobility patterns within the metro network. Results show that the OD (origin to destination) flows can be characterized well by shifted power law distributions with similar exponents around 2, which reflects the fact that a few OD pairs in the system play a dominant role and undertake disproportionately large OD flow distribution. The different exponents signify heterogeneous human movement in within- and between-day ranges. In addition, we analyze the metro community structures over different time periods based on the community detection method using random walks to visualize and understand passenger movement from a spatial perspective. Normalized mutual information is used to compare community partitions over different time-intervals. The results show that the properties of human mobility during different time periods have a similar rhythm, although some nuances exist, and the community structure is usually divided according to the line distribution. This empirical study provides spatiotemporal insights into understanding urban human mobility and some potential applications for transportation management.

Existing parking guidance systems only provide road guidance outside the parking lot but do not provide accurate guidance to specific parking spaces inside the parking lot. By using a Kalman filter, the Grubbs test, and a neural network algorithm to improve the RSSI-based location fingerprint identification technology, an accurate location method based on indoor Wi-Fi is obtained, which implements precise route guidance and a reverse search function for parking spaces. We utilize Beidou positioning to develop a Gaode map for outdoor navigation and use an integrated system of ultrasonic detector/indicators and ground locks to manage parking spaces. Through the secondary development of an Android system and the application of a MySql database, an app for precise parking guidance was developed. The system makes full use of the Internet and parking information, eliminates information asymmetry, improves the utilization ratio of the urban static traffic resources, allocates parking spaces in real-time, breaks information islands, provides parking search and recommendation functions for users, achieves parking information-sharing, and effectively improves parking efficiency and the parking utilization ratio.
Optimization of the Suburban Railway Train Operation Plan Based on the Zonal Mode
Authors: Yang Yongbin , Du Peng
Published: June 2021

Traditional all-stop train operation mode cannot meet the demand of long travel distance and centralized travel of commuters very well. To meet this special travel demand, a zonal train operation mode based on “many-to-many” train stops is proposed. The coefficient of passenger exchange is used to locate suburban areas by depicting travel characteristics of commuters. Operational separating points within the suburban area are used as decision variables to analyze the combined cost components of this model, including passenger travel costs and railway operating costs. An integer programming model with the lowest overall cost is established, and the genetic algorithm is employed to solve it. The results proved good relative benefits in operation costs and travel time. And the sensitivity analysis of both coefficient of passenger exchange and passenger intensity has shown that the zonal operation mode is suitable for suburban railways with centralized travelers. However, the research also shows that when the passenger volume rose to a very high level, the number of zones would be limited by the maximized capacity of railway lines, which may cause the decline of the relative operational efficiency.
A Hybrid Deep Convolutional Neural Network Approach for Predicting the Traffic Congestion Index
Authors: Tran Quang Duy , Bae Sang Hoon
Published: June 2021

Traffic congestion is one of the most important issues in large cities, and the overall travel speed is an important factor that reflects the traffic status on road networks. This study proposes a hybrid deep convolutional neural network (CNN) method that uses gradient descent optimization algorithms and pooling operations for predicting the short-term traffic congestion index in urban networks based on probe vehicles. First, the input data are collected by the probe vehicles to calculate the traffic congestion index (output label). Then, a CNN that uses gradient descent optimization algorithms and pooling operations is applied to enhance its performance. Finally, the proposed model is chosen on the basis of the R-squared (R2) and root mean square error (RMSE) values. In the best-case scenario, the proposed model achieved an R2 value of 98.7%. In addition, the experiments showed that the proposed model significantly outperforms other algorithms, namely the ordinary least squares (OLS), k-nearest neighbors (KNN), random forest (RF), recurrent neural network (RNN), artificial neural network (ANN), and convolutional long short-term memory (ConvLSTM), in predicting traffic congestion index. Furthermore, using the proposed method, the time-series changes in the traffic congestion status can be reliably visualized for the entire urban network.
