Abstract
The world is social distancing and compulsory confinement has caused stress, psychological instability, stigmatization, fear, and discrimination in the general population. In this cross-sectional survey study, we administered the Fear of COVID-19 Scale (FCV-19S) to hospital medical and nonmedical personnel. A total of 1,216 participants were surveyed from May 25 to May 29 of 2020. We asked all the staff for their participation in the study and physical copies of the survey were distributed to the staff willing to participate. All surveys were answered anonymously. We found that the global FCV-19S mean score was 16.4 ± 6.1, with a significant difference between women and men’s scores. Medical students presented higher scores than experienced medical personnel. Additionally, the medical and nursing personnel presented a higher level of fear than hospital staff who did not work directly with COVID-19 patients. Our findings suggest that greater knowledge of medicine or infectious diseases could decrease the overall psychological impact of the pandemic disease.

The Effectiveness of Low-Investment Pachinko/Pachislot in Reducing Gambling-Related Harms: A Cross Sectional Study
Authors: Yokomitsu Kengo , Inoue Kazuya , Irie Tomonari 
Published: July 2021

Abstract
BackgroundPachinko and pachislot are popular types of gambling activities in Japan. Prior studies in Japan have reported a concerning prevalence of problem gambling among adult players. While these studies have identified various gambling-related harms, Japanese research on harm-minimization strategies is scarce. Therefore, the present study aimed to analyze the effectiveness of low-investment pachinko and pachislot as a harm-reduction strategy. MethodsWe considered gamblers who played games that cost the typical amount of money to be “normal-pachi players.” Those who played low-investment games were categorized as “half-pachi players” and “quarter-pachi players,” reflecting those who played games at half or one quarter the cost of a typical machine, respectively. To assess the harm-reduction effect, a one-way ANCOVA was conducted to compare the impact of the groups (normal-pachi players [n= 101], half-pachi players [n= 104], and quarter-pachi players [n= 100]) on dependent variables, namely the number of days players had gambled during the prior month; total time and amount of money spent on gambling; debts caused by gambling; gambling severity; cognitive distortion; depressive symptoms; and problems in work, family, and social life. ResultsWe demonstrated that the amount of money spent by quarter-pachi players on gambling during the past month was lower than that of normal-pachi players. However, we did not find significant differences with respect to any other gambling-related harms among normal-, half-, and quarter-pachi players. ConclusionLow-investment pachinko and pachislot can reduce the amount of money spent on gambling. It can thus partly act as a harm-minimization strategy. Moreover, the results of the present study indicate that the problems at work affect various outcomes for gamblers. Given that 90% of the participants in this study were employed, the results of this study may have important implications for employed gamblers.

Published: July 2021

Abstract
We develop a dynamic computable general equilibrium (CGE) model to assess the macroeconomic impacts of water scarcity and water (in)security in South Africa. The water-CGE model which includes a detailed representation of water flows (surface water, groundwater, wastewater, and seawater) has been calibrated with an updated social accounting matrix enabling to conduct policy simulations up to 2030. We show that water scarcity will have an impact on the South African economy. With an increase of water scarcity by 17%, the CGE model predicts a decrease of South African GDP by -0.34% in 2030. The long-term impact of water scarcity varies from one sector to another, with the most negatively impacted sectors being those related to water (loss of GDP up to -2.48%). Due to the increase of water scarcity, the unemployment rate is expected to be 0.1% higher in 2020 which represents a loss of 18,000 jobs compared to the baseline year (2013). The 17% increase in water scarcity is also expected to have a negative impact on household welfare: by 2030, household consumption may decrease by -0.26%. Some policies can mitigate the negative impacts of water scarcity, the most promising one being to promote water saving.

Abstract
Intestinal malrotation is a congenital intestinal rotation anomaly and can present with various symptoms. Electrolyte disorders are very common in childhood. Pseudo-Bartter syndrome (PBS) is one of the conditions that causes electrolyte disorders and can be seen due to intestinal malrotation in children.A 3.5-month-old boy who was diagnosed as having malrotation is reported. The patient had PBS because of non-bilious vomiting. We could find only two reports on PBS related to malrotation. It is emphasized that intestinal malrotation should be considered in patients presenting with gastrointestinal symptoms such as vomiting, abdominal pain, and also PBS.
A Novel Dual-Band Conformal Surface Plasmons Waveguide With Tunable Frequency Response In Large-scale
Authors: Fang Yijiao , Zhong Jiangwei 
Published: July 2021

Abstract
A novel dual-band conformal surface plasmons (CSPs) waveguide is designed and well studied in this paper. In earlier researches, we have recognized that electromagnetic field of CSPs waveguide are always confined to a sub-wavelength area and have a strong potential to be applied in devices designing. However, almost all of the earlier CSP structures is mainly focus on the fundamental mode characteristics with only single resonance frequency. Here we propose a innovative dual inverted-L structure with excellent performance not only on the fundamental mode but also on a new upper mode. This structure operates in microwave frequencies regime and shows outstanding frequency tunability characteristic. Being different from frequency characteristics in the earlier CSP waveguides which always used to be designed single-frequency device, dual-frequency tunability can be obtained via the dual L-type bending branch of the periodical CSP structure. In present paper, we also realize a tunable dual-frequency filter by changing the scaling factor of inverted-L stubs.

Abstract
Infrastructure service model provides different kinds of virtual computing resources such as networking, storage service, and hardware as per user demands. Host load prediction is an important element in cloud computing for improvement in the resource allocation systems. Hosting initialization issues still exist in cloud computing due to this problem hardware resource allocation takes serval minutes of delay in the response process. To solve this issue prediction techniques are used for proper prediction in the cloud data center to dynamically scale the cloud in order for maintaining a high quality of services. Therefore in this paper, we propose a hybrid convolutional neural network long with short-term memory model for host prediction. In the proposed hybrid model, vector auto regression method is firstly used to input the data for analysis which filters the linear interdependencies among the multivariate data. Then the enduring data are computed and entered into the convolutional neural network layer that extracts complex features for each central processing unit and virtual machine usage components after that long short-term memory is used which is suitable for modeling temporal information of irregular trends in time series components. In all process, the main contribution is that we used scaled polynomial constant unit activation function which is most suitable for this kind of model. Due to the higher inconsistency in data center, accurate prediction is important in cloud systems. For this reason in this paper two real-world load traces were used to evaluate the performance. One is the load trace in the Google data center, while the other is in the traditional distributed system. The experiment results show that our proposed method achieves state-of-the-art performance with higher accuracy in both datasets as compared with ARIMA-LSTM, VAR-GRU, VAR-MLP, and CNN models.

Published: July 2021

Abstract
In the present work, authors have demonstrated how a localized induction heat treatment can be advantageously applied, controlled and mechanically characterized on a specific part – i.e. on steel hose fittings for hydraulic applications. More specifically, the study shows how this specific type of heat treatment facilitates the acquisition of significant localization effects on mechanical properties, and how such a treatment could act as a powerful tool for material optimization in diverse applications. The instrumented micro-indentation test was adopted as the investigation method for mechanical characterization and, due to the reduced amount of material required for the test, has the double advantage of retrieving potential spatial gradients of the mechanical properties without causing permanent damage to the entirety of analyzed parts. The measurement of both the Vickers hardness and plastic work required to make the indentation that would be necessary to quantify the strength and ductility capability of the parts’ material. In addition, a customized tensile test, based on the strains measurement obtained through an optical full-field method – i.e. Digital Image Correlation (DIC) – was developed with the aim of identifying and quantifying the correlation between the material properties attainable through a conventional tensile test and those measured by the instrumented micro-indentation test. Finally, it was demonstrated that the proposed customized tensile test, due to the localized heat treatment, is capable of retrieving potential spatial gradients of material properties.

Abstract
Alzheimer’s disease (AD) is a neurodegenerative condition associated with oxidative stress and neuroinflammation. Lycopene has previously been shown to ameliorate neuroinflammation and exert protection against oxidative damage in neuroblastoma cells. The role of this compound in reversing cognitive dysfunction in AD has yet to be determined. The present study investigates the role of lycopene in AD with an in vitro Aβ1-42-induced cell cytotoxicity model as well as the in vivo APP/PS1 mouse model. The activation of Nrf2 signal pathway was assessed using western blot and RT-PCR. MDA, 8-OHdG, ROS, SOD, GHS and GSSG measurements were carried out using the specialized assay kits. The Morris water maze was used to examine qualitative assessment of memory and spatial learning. Immunofluorescence was used to visualize astrocytes and microglia activation as well as brain β-amyloid (Aβ) deposition. The NeuN positive cells were detected by immunofluorescence and western blot. Levels of cerebral cytokines were quantified using RT-PCR. Lycopene ameliorates oxidative damage in the Aβ1-42-triggered cell cytotoxicity model via Nrf2-ARE signal pathway activation, which is regulated by AKT-GSK3β pathway. In addition, lycopene improves the cognitive impairment and reduces the Aβ deposition. Mechanistically, lycopene attenuates neuron loss, decreases chronic inflammation and activates cerebral Nrf2-ARE signaling pathway in APP/PS1 mice. The results suggest that lycopene alleviates oxidative stress via AKT- Nrf2-ARE pathway. And early administration of lycopene improves cognitive deficits by reducing Aβ deposition, neuronal loss and decreasing the degree of chronic inflammation.
Spatial-temporal Attention Fusion for Traffic Speed Prediction

Published: July 2021

Abstract
Accurate vehicle speed prediction is of great significance to the urban traffic intelligent control system. However, in terms of traffic speed prediction, the modules that integrate temporal and spatial features in the existing traffic speed prediction methods are effective in short-term prediction, but the medium-term or long-term prediction errors are relatively large. Aiming at this limitation, this paper proposes a traffic speed prediction method that combines attention and Spatial-temporal features, referred to as ASTCN. Specifically, unlike previous methods, ASTCN can use the temporal attention convolutional network (ATCN) to separately extract temporal features from the traffic speed features collected by each sensor, and use the spatial attention mechanism to extract spatial features and then perform spatial-temporal feature fusion. Experiments on three real-world datasets show that the proposed ASTCN model outperforms the state-of-the-art baselines.

Abstract
PurposeSince the publication of the Z0011 trial, practice-changing clinical guidelines for breast surgery have been developed. Although recent studies confirmed the feasibility of the Z0011 strategy in Asian populations, there has been no study on the trends of axillary surgery in Asian cohort. This study aimed to investigate the time trend of axillary surgery for breast cancer in Korea and compare it with that in Dutch cohort to understand the impact of the Z0011 trial.MethodsWe collected prospectively constructed data from the nationwide Korean Breast Cancer Registry (KBCR). We identified patients who underwent sentinel node biopsy followed by breast-conserving surgery from 2011 to 2018 and were found to have pathological stage T1-2N1-3M0 disease. Regression analyses were performed to compare the downward trend of axillary lymph node dissection (ALND) in our cohort with that previously reported in a Dutch cohort.Results From KBCR data, 7,478 patients met the inclusion criteria. The proportion of ALND significantly decreased from 2011 (76.6%) to 2018 (47.5%). Multivariate analysis revealed that earlier year at diagnosis, larger tumor size, and lymphatic invasion were associated with a higher odds ratio of performing ALND. Compared to Dutch cohort, the downward trend of ALND in Korea was significantly more gradual (annual percent change: 30.1% vs. 5.8%, P < 0.001).ConclusionsThis study demonstrated a downward trend of ALND in Korean patients with breast cancer. However, the rate of decrease was significantly slower than that in Dutch cohort, indicating the need to spread the Z0011 strategy in Asia.

Published: July 2021

Abstract
Resistance spot welding (RSW) is a widespread manufacturing process in the automotive industry. There are different approaches for assessing the quality level of RSW joints. Multi-input-single-output methods, which take as inputs either the intrinsic parameters of the welding process or ultrasonic nondestructive testing variables, are commonly used. This work demonstrates that the combined use of both types of inputs can significantly improve the already competitive approach based exclusively on ultrasonic analyses. The use of stacking of tree ensemble models as classifiers dominates the classification results in terms of accuracy, F-measure and area under the receiver operating characteristic curve metrics. Through variable importance analyses, the results show that although the welding process parameters are less relevant than the ultrasonic testing variables, some of the former provide marginal information not fully captured by the latter.

Abstract
Post-operative infections in orthopaedic implants are severe complications that require urgent solutions. Although conventional antibiotics limit bacterial biofilms formation, they ignore the bone loss caused by osteoclast formation during post-operative orthopaedic implant-related infections. Fortunately, enoxacin exerts dual antibacterial and osteoclast inhibitory effects, playing a pivot in limiting infection and preventing bone loss. However, enoxacin lacks specificity in bone tissue and low bioavailability-relate side effects, which hinders translational practice. Herein, we developed a nanosystem (Eno@MSN-D) based on enoxacin (Eno)-loaded mesoporous silica nanoparticles (MSN), decorated with the eight repeating sequences of aspartate (D-Asp8), and coated with polyethylene glycol (PEG). This Eno@MSN-D delivery nanosystem exhibited both antibacterial and anti-osteoclast properties in vitro. More importantly, Eno@MSN-D allowed the targeted release of enoxacin in infected bone tissues and prevented implant-related infection and bone loss in vivo. Therefore, our work highlights the significance of novel biomaterials that offer new alternatives to treat and prevent orthopaedic staphylococcus aureus-related implantation infections and bone loss.

Abstract
The cardiac evaluation of wild animals is still a wide and largely unknown field for several species. Therefore, through complimentary examinations such as radiography, echocardiography and serum troponin levels, this study aimed at describing the values observed in 12 crab-eating foxes (Cerdocyon thous) anesthetized with a combination of intramuscular ketamine and midazolam. Through the use of this chemical restraint, a clinical, radiographic and echocardiographic (linear and indexed values in M-mode) evaluation of the 12 male specimens included in the sample group. Among the findings observed in comparison with domesticated dogs were a decrease in the dimensions of the septum, wall and cavity of the left ventricle, as well as a deceleration in the E wave (EDT), which could be correlated with the maintenance of the serum troponin dosage values (cTnI). Therefore, M-mode echocardiography has proven to be safer and comparative to other species of wild canids when performed through indexed values. In addition, when evaluating the systolic function and segmentary contractions, the anesthetic combination did not have any effects on the results of complementary examinations performed in crab-eating foxes (Cerdocyon thous) included in this study.

Abstract
This study aimed to evaluate the influence of age and sex on the blood biochemical constituents of broiler breeders during the egg production stage. The analysis was performed in an industrial broiler breeder farm, and blood samples were collected from males and females at five different ages. At most ages, females had higher values of total proteins, albumin, globulins, triglycerides, cholesterol, glucose, calcium, phosphorus, Ca/P (calcium and phosphorus)ratio and gamma-glutamyltransferase (GGT). The values of uric acid, aspartate aminotransferase (AST), creatine kinase (CK), and alkaline phosphatase (PAL) were higher in males. The lowest protein values were found at 28 and 60 weeks old. The mean albumin values were significantly higher at 44 and 52 weeks old in males and females. A trend of increasing globulin values ​​with increasing age up to 52 weeks old was observed. Although calcium and phosphorus did not vary according to age, the Ca/P ratio was lowest at 36 weeks old. Comparing the means of both sexes, the AST and GGT values were significantly higher in 60-week-old birds. The highest serum levels of CK occurred at 28 and 52 weeks old. The physiological levels of serum biomarkers presented in this work are important for evaluating productivity performance, welfare, and disease indication in breeding flocks.
