Published: June 2020

Küçülme, performans ya da davranış gibi çeşitli sebeplerle ortaya çıkan işten çıkarma uygulamaları, çalışma yaşamında önemli bir yere sahiptir. Gelişen teknoloji ve insanların her an her yerde ulaşabildikleri sosyal medya araçlarının yaygınlaşmasıyla birlikte işten çıkarma sebepleri de değişmiştir. Bu araştırmanın amacı, çalışanların sosyal medya paylaşımlarının işten çıkarma sebebi oluşturup oluşturmayacağını incelemektir. Çalışanların yaptıkları sosyal medya paylaşımları, işten çıkarma ve mahremiyet bağlamında değerlendirilmiştir. Araştırmada nitel araştırma türlerinden örnek olay yöntemi kullanılarak işten çıkarma ve sosyal medya olgularını temsil niteliği taşıyan örnekler derinlemesine incelenmiştir. Araştırma sonucunda, çalışanların mahremiyeti göz ardı ederek sosyal medya platformlarında yaptıkları paylaşımların işten çıkarma sebebi olabileceği görülmüştür. Nitekim çalışanın raporlu olduğu günde sosyal medyada plajdan tatil fotoğrafı paylaşmasının, sosyal medyada insan kaynaklarını hedef alarak sataşma niteliğinde söylemde bulunmasının, iş sözleşmesini kölelik sözleşmesi olarak nitelendirmesinin ve işyerinden kurumun logosunun göründüğü iş disiplinini bozan fotoğraf paylaşmasının işten çıkarma sebebi olabileceği ortaya çıkmıştır. Çalışmanın en önemli katkısı, sosyal medya sebebiyle işten çıkarma olgusunu mahremiyete yönelik modern tehditler olan ifşa ve gözetim bağlamında incelemesidir. Artık sosyal medya sadece işe alımda değil işten çıkarmada da işverenler için değerlendirme unsuru haline dönüşmüştür.
Scaleup of Laboratory Data for Surfactant-Alternating-Gas Foam Enhanced Oil Recovery
Authors: Salazar-Castillo Rodrigo O. , Rossen William R.
Published: June 2020

Foam increases sweep efficiency during gas injection in enhanced oil recovery processes. Surfactant alternating gas (SAG) is the preferred method to inject foam for both operational and injectivity reasons. Dynamic SAG corefloods are unreliable for direct scaleup to the field because of core-scale artifacts. In this study, we report fit and scaleup local-equilibrium (LE) data at very-low injected-liquid fractions in a Bentheimer core for different surfactant concentrations and total superficial velocities.

We fit LE data to an implicit-texture foam model for scaleup to a dynamic foam process on the field scale using fractional-flow theory. We apply different parameter-fitting methods (least-squares fit to entire foam-quality scan and the method of Rossen and Boeije 2015) and compare their fits to data and predictions for scaleup. We also test the implications of complete foam collapse at irreducible water saturation for injectivity.

Each set of data predicts a shock front with sufficient mobility control at the leading edge of the foam bank. Mobility control improves with increasing surfactant concentration. In every case, scaleup injectivity is much better than with coinjection of gas and liquid. The results also illustrate how the foam model without the constraint of foam collapse at irreducible water saturation (Namdar Zanganeh et al. 2014) can greatly underestimate injectivity for strong foams.

For the first time, we examine how the method of fitting the parameters to coreflood data affects the resulting scaleup to field behavior. The method of Rossen and Boeije (2015) does not give a unique parameter fit, but the predicted mobility at the foam front is roughly the same in all cases. However, predicted injectivity does vary somewhat among the parameter fits. Gas injection in a SAG process depends especially on behavior at low injected-water fraction and whether foam collapses at the irreducible water saturation, which may not be apparent from a conventional scan of foam mobility as a function of gas fraction in the injected foam. In two of the five cases examined, this method of fitting the whole scan gives a poor fit for the shock in gas injection in SAG. We also test the sensitivity of the scaleup to the relative permeability krw(Sw) function assumed in the fit to data.

There are many issues involved in scaleup of laboratory data to field performance: reservoir heterogeneity, gravity, interactions between foam and oil, and so on. This study addresses the best way to fit model parameters without oil for a given permeability, an essential first step in scaleup before considering these additional complications.

Authors: Song Wenhao , Gong Yao , Tu Pei , Zhang Lin , Jin Zhili , Wang Hairong
Published: June 2020

Background

The aim of this study was to analyze the expressions of long noncoding RNA(lncRNA) in rat with type 2 diabetes mellitus(T2DM) complicated with acute myocardial ischemia reperfusion injury(IRI).
Methods

Type 2 diabetic rats were induced by high calorie diet combined with streptozotocin. IRI rats models were established by the ligation and release of left anterior descending coronary artery(LAD). The expression levels of lncRNA and mRNA in myocardial tissues of rats were detected via high-throughput sequencing technology, and Gene Ontology analysis and Kyoto Encyclopedia of Genes and Genomes pathway analysis were performed.
Result

Transcriptome analyses were performed to show expression profiles of mRNAs and lncRNAs in myocardial tissues of diabetic rats with IRI. A total of 2,476 lncRNAs and 710 mRNAs were differentially expressed between operation group and sham operation group. Then, an mRNA-lncRNA coexpression network was constructed. Finally, the present study verified that TCONS_00036439、TCONS_00151548、TCONS_00153276、TCONS_00344188、TCONS_00277692、TCONS_00236469、TCONS_00236468、TCONS_00153290、TCONS_00360941、TCONS_00142622 were associated with the initiation and development of ischemia reperfusion injury. Then, an lncRNA-mRNA coexpression network was constructed.
Conclusion

There is differential expression of lncRNAs in myocardial IRI tissues of diabetic rats. Building gene regulation networks to find the nodal gene and lncRNA is useful for understanding the pathogenesis of type 2 diabetes mellitus complicated with acute myocardial ischemia reperfusion injury and providing new therapy target.

Background During the outbreak period of COVID-19 pneumonia, cancer patients have been neglected and in greater danger. Furthermore, the differential diagnosis between COVID-19 pneumonia and radiation pneumonitis in caner patients remains a challenge. The study aimed to determine their clinical presentations and radiological features to familiarize radiologists and clinical teams with them in order to early diagnosis and prompt early patient isolation.Methods From January 21, 2019 to February 18, 2020, the patients selected consecutively met the following criteria: (i) presumed COVID-19 pneumonia; (ii) patients with a history of malignancy and lung exposure to ionizing radiation. A retrospective analysis including all patients’ presenting was performed.Results 4 patients from 112 suspected individals were selected, including 2 males and 2 females with a median age of 54 years (39–64 years). After repeated pharyngeal swab nucleic acid tests, 1 case was confirmed and 3 cases were excluded from COVID-19 pneumonia.Conclusions Despite the comparable morphologic characteristics of lung CT imaging, the location, extent, and distribution of lung lesions between COVID-19 pneumonia and radiation pneumonitis differ significantly, further combined with clinical and laboratory findings that could facilitate early diagnosis and appropriate management.

Background The effect of pharmacological treatment (PT), exercise treatment (ET), and both in depressive symptoms remains a matter of debate. The present study aimed to clarify (1) the effect of ET as a monotherapy or complementary treatment of pharmacological therapy; (2) changes in the dose-response for different exercise prescription characteristics; and 3) hypothesizing about the gene network model of exercise effects on depression. Methods We sought Randomized Controlled Trials (RCT) addressing the effects of exercise on depressive patients, published in peer-reviewed journals between 2003-2019 in Scopus, Cochrane, Pubmed/Medline, ISI Web of Knowledge and APA PsycNET databases. Standardized mean difference (SMD) was calculated considering the mean difference on depression scales (pre and post-intervention) and pooled standard deviation for each intention-to-treat in each study. For the gene network model of exercise on depression an in silico analyses were used. Results We found 1,165 articles and selected 15 studies to this meta-analysis. RCTs with different ET and PT prescriptions were examined using the delta (pre and post-intervention) of a validated depression scale compared to the control group in different treatment conditions.Standardized mean differences and confidence intervals (SMD, 95% CI) were found for ET with or without PT group (-0.45, -0.62 to -0.29), ET and PT group (-0.70, -1.00 to -0.40), and only ET group (-0.39, -0.57 to -0.21). The subgroup analyses showed a moderate and large SMD in favour of resistance training (-0.67, -1.22 to -0.12), aerobic exercise 60-80% of maximum heart rate intensity (-0.56, -0.89 to -0.23), 20 to 30 minutes (-0.59, -0.88 to -0.31) or 45 to 60 minutes (-0.55, -0.81 to -0.29) duration per session, and seven times per week (-0.75, -1.30 to -0.20). Conclusion ET plus PT showed a better effect on reducing depressive symptoms, and the exercise prescription that shows the best dose-response in subgroup analyses can be the target for ET in depression. Also, the genes network model can withstand the effect of exercise in the depressive symptoms decrease according to an interaction between BDNF and inflammation. More well-designed studies are needed to confirm our findings.

The information was collected from mothers having a child within last five years preceding the survey years.The total number of such mothers was 4066, 4148, and 3998 respectively in the survey of 2006, 2011, and 2016.The association between institutional delivery and the explanatory variables was assessed via bivariate analysis (chi-square test) and multivariate analysis (binary logistic regression).Results The utilization of health service during delivery stepped up from 21% in 2006 to 62% in 2016.Although the proportion of delivery in health facility increased among poorest over the period of 10 years, the disparity between richest and poorest still persisted from 2006 to 2016 and the association was highly significant in all the surveys. Although, government of Nepal has launched the maternity incentive scheme through safe delivery incentive program in 2005, poor women are still deprived from utilizing the service. Poorest and poorer women were 78 percent (aOR = 0.22, 95% CI 0.17–0.27) and 71 Percent (aOR = 0.23, 95%CI 0.23–0.35) respectively less likely to have institutional delivery than the richest women after controlling the other socio-demographic and culture factors. Furthermore, this study found that education, place of residence, women’s autonomy, religion, number of ANC visits, exposure to newspaper and TV were significant predicators for place of delivery.Conclusion Although there has been three-fold increment in utilization of health services during delivery over the period of 10 years, the discrepancy between rich and poor, educated and uneducated and urban and rural area is highly evident. Overall, our study highlights the necessity of interventions to promote institutional delivery with greater focus on poor, uneducated, and rural women.

Background: Sigmoid volvulus is a major cause of mechanical large bowel obstruction in volvulus belt countries. The objective of this study to explore the magnitude and clinical characteristics of Sigmoid Volvulus Methods: Hospital-based retrospective cross-sectional study employed in Debre Tabor general hospital Northcentral Ethiopia. A medical review conducted on the medical chart from Jan1, 2016 to Dec31, 2019. The collected data checked manually for completeness and consistency. The final data coded and entered to SPSS version 23 for data processing and analysis. Binary logistic regression used to measure the association of each covariate with the outcome variable. In addition, factors that have p=0.25 with the outcome variables were taken into a multivariable logistic regression analysis to control the potential confounders. The result of the final model expressed in terms of adjusted Odd Ratios (AOR) and 95% CI and statistical significance declared if the P-value is less than 0.05.Result: There were 124 patients with sigmoid volvulus admitted within four years of the study. During the study period, 408 patients with bowel obstructions were admitted, among Mechanical large bowel obstruction (MLBO) 135 (33.1%), Mechanical small bowel obstruction (MSBO) 251(61.5%), and Ileosigmoid knotting 22(5.4%). Our study showed that sigmoid volvulus accounted for 91.9% and 30.4% of Mechanical Large bowel obstruction and Bowel obstruction respectively. Most of the patients were male 97.6 %( N=121) and rural residents 91.1 %( N=113). The peak age was 56-65 years accounted for 29 % and 65.3 %( N=81) of patients were above age 50years. The age ranged from 19-88 years. The mean and median ages were 56.52± (SD=14.4) and 58.5± (IQR=17.75) respectively. The mean of hospital stay for elective admission was 10.98(SD±4.33) days and the median was 11 (IQR±5) days. The mean of hospital stay for emergency admission excluding death and leave against medical advice was 8.4(SD±4.1) days and median was 8 (IQR±2) days Conclusion: Primary resection and anastomosis was the common procedure for management of sigmoid volvulus. Mortality rate was 6.45% and higher in gangrenous sigmoid volvulus (14.6 % vs. 2.4%)

Background: Upper respiratory tract specimens are widely applicable for the diagnosis of COVID-19. To date, no study has analyzed the actual viral loads in upper respiratory tract and its relationship with the severity of lung lesions, Ct value of RT-PCR and transmission capacity in COVID-19 patients.Methods: We retrospectively enrolled nine COVID-19 patients. Clinical data and close contacts of these patients were investigated. Respiratory samples were tested for SARS-CoV-2 with both normal RT-PCR and droplet digital PCR.Results: All the COVID-19 patients complicated with pneumonia. Viral loads in nasopharyngeal swabs were accurately quantified, and they had no direct correspondence with the severity of lung lesions. The Cycle Threshold (Ct) value of RT-PCR was approximately consistent with the absolute quantification of digital PCR. The spearman correlation coefficient between them was -0.952 with P value < 0.001. Close contacts of patients with very low viral load or no detected virus were not infected.Conclusions: Viral loads in nasopharyngeal swabs, could not predict the severity of lung lesions revealed by CT in COVID-19 patients. The infectious capacity of patients with low or absent viral load in upper respiratory tract was relatively weak, and wearing mask might be helpful for lower its spread.

Background Numerous studies have been focused on the clinical and imaging features among COVID-19 patients positive for SARS-CoV-2, but the data after negative is limited. We aims to describe these features after negative respiratory nucleic acid testing results.Methods From January 31 to February 28, 2020, 51 mild-to-moderate COVID-19 cases (median: 34.0 years and 47.1% male) were retrospectively enrolled. Demographic, clinical, laboratory, and CT imaging data were collected before and after two sequential negative results for respiratory SARS-CoV-2 .Results After negative for respiratory SARS-CoV-2, the clinical symptoms continued to recover and the abnormal imaging were observed for all of the moderate cases. 77.4% of the moderate patients had multi-lobar involvement and lesions were more frequent in the lower lobes. The most common CT imaging manifestations were ground glass opacity (51.6%) and fibrous stripes (54.8%%). Among 12 out of 31 moderate patients with repeated chest CT scan after negative for SARS-CoV-2, 7 patients (58.3%) with ground-glass absorption reduced over 60% within one week, but there were still 4 cases (13.8%) with absorption less than 5%.Conclusions The clinical symptoms and abnormal imaging persisted but continued to recover after negative for respiratory SARS-CoV-2.

Autonomous vehicles need to have the ability to predict the future behavior of surrounding vehicles, which helps with proper trajectory planning and tracking. Many behavior prediction methods have limited application because they have a very limited prediction horizon. This paper proposes a deep learning-based hybrid model for behavior prediction over long-time periods, including maneuver recognition and a behavior prediction module. In the previous module, the CNN extracts the social characteristics of the target vehicle and LSTM outputs the maneuver probability vector and forms a contextual feature vector with the social features. In the lateral module, LSTM and Attention are based on the contextual feature vector to capture multi-time step information in the behavior time window to complete the prediction of the target vehicle behavior. Real-car collection and open-source vehicle trajectory datasets were used for training and testing. The results show that the proposed algorithm could predict vehicle behavior with an accuracy of 89.73% and an average prediction time of 2.032 s, which has a high engineering application value.

Background To analyse the clinical characteristics, laboratory tests, and imaging findings of severe cases of coronavirus disease 2019 (COVID-19) versus severe cases of influenza A (H1N1).Methods We retrospectively analysed the clinical data of moderate and severe COVID-19 and H1N1 cases between January 23 and February 23, 2020.Results A total of 33 COVID-19 cases had a clear history of exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with an incubation period of 11.12 ± 7.47 days. A total of 29 H1N1 cases were included in this study. Most cases were sporadic, with an incubation period of 3.67 ± 0.82 days (P = 0.002). The age at onset was 19.79 ± 23.88 years for H1N1 and 43.48 ± 17.82 years for COVID-19 (P < 0.001). For H1N1, common clinical symptoms were high fever and myalgia. The time of disease progression from moderate to severe was 13.60 ± 5.64 days for COVID-19 and 5.25 ± 2.36 days for H1N1 (P = 0.035). Laboratory tests showed that white blood cells (WBC), neutrophils (N), lactate dehydrogenase (LDH), C-reactive protein (CPR), and procalcitonin (PCT) were significantly higher in severe H1N1 cases than in severe COVID-19 cases. D-dimer (DD) was 1.43 ± 1.19 µg/mL in the COVID-19 group, which was higher than that in the H1N1 group (0.88 ± 0.32 µg/mL, P = 0.013). High-resolution computed tomography (CT) showed severe COVID-19 cases presented mainly interstitial involvement, shown by large ground-glass opacities, whereas severe H1N1 cases presented both interstitial and parenchymal involvement, especially parenchymal involvement. All the COVID-19 patients survived to discharge, and one H1N1 patient died.Conclusion Compared with H1N1 patients, COVID-19 patients had a clear history of exposure to SARS-CoV-2, were older, presented milder clinical symptoms and a slower progression, and rarely had bacterial infections. Most H1N1 patients had sporadic H1N1 with an acute onset, high fever, and rapid progression; secondary bacterial infection was an important cause of disease aggravation.

Background: Lower respiratory tract infections（LRIs）were a very common disease, no matter in community acquired infection or hospital acquired infection. Sputum and bronchoalveolar lavage fluid (BALF) were the most important specimens of LRIs. The choice of antibiotics for the treatment of LRIs usually depended on the results of antimicrobial sensitivity of bacteria isolated from sputum and BALF. However, it was rarely reported to compare the pathogens isolated from sputum and BALF and the difference of antimicrobial sensitivity.Methods: A retrospective study was conducted to analyze the differences between sputum and BALF samples in pathogen isolation and antimicrobial sensitivity in our hospital. Results: In our hospital during 2013-2015 year, the quality evaluation of sputum samples was not conducted before sputum culture, but in 2016-2018 year, the quality evaluation of sputum samples was conducted firstly and only qualified sputum samples were cultured. The results of pathogen culture showed that Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus and Haemophilus influenzae were the top five pathogens isolated from sputum and BALF. Antimicrobial susceptibility test showed for these five pathogens the susceptibility rates of BALF isolates to most antibiotics were higher than those isolated from sputum. The sensitivity of A. baumannii to common antibiotics was less than 50%. In particular, the detection rate of carbapenem resistant A. baumannii (CR-ABA) in sputum and BALF was higher than 80%. The sensitivity of P. aeruginosa to antibiotics other than ticarcillin/clavulanic acid and minocycline were higher than 50%. The detection rate of carbapenem resistant Klebsiella pneumoniae (CR-KPN) was 10% - 20% in 2013-2015 and 30% - 50% in 2016-2018. The detection rate of MRSA in sputum was higher than 80%, while that in BALF was 65% - 70%. The separation rate of beta-lactamase-negative ampicillin-resistant H. influenzae (BLNAR) was between 0-6%.Conclusions: The sensitivity of strains isolated from BALF to commonly used antibiotics was generally higher than that from sputum. MRSA, CR-KPN and A. baumannii were the focus of infection control for LRIs.
