This work examines the results of a soil incubation experiment in the laboratory, under controlled conditions of humidity and temperature. The purpose was to determine the medium-term influence of the presence of antibiotics on the total and specific microbial biomass, determined by means of the phospholipid fatty acids (PLFAs) analysis (total microbial biomass, and specific fungal, bacterial, actinobacterial, Gram-negative bacterial and Gram-positive bacterial biomass), as well as the relationship between some of these groups (fungal biomass/bacterial biomass, Gram-negative-bacterial /Gram-positive bacterial). The experiment was performed with four different cultivated soils with a similar pH but different organic matter (OM) content, to which eight doses of three antibiotics of the tetracycline group (tetracycline, oxytetracycline and chlorotetracycline) were added. Microbial biomass measurements (total and specific groups) were performed after 42 days of incubation. As expected, the total and specific microbial biomass values were different in the four soils studied. Both the total and the specific microbial biomass showed a similar response to the presence of antibiotics, although in several cases the data were inconsistent and difficult to interpret. In general, in all soils the addition of chlorotetracycline and tetracycline slightly modified or increased, to a greater or lesser extent, the values of both total and specific microbial biomass, particularly at higher doses. However, in certain cases, biomass values decreased due to the addition of the highest dose of oxytetracycline. With regard to fungal/bacterial and Gram-bacteria/Gram+ bacterial biomass ratios, values slightly changed after the addition of the antibiotics.

Segmentación semántica consiste en encontrar objetos previamente definidos en una imagen digital y se aplica en tecnologías como vehículos autónomos, interacción humano-maquina, realidad aumentada, robótica, etc. Los modelos más comunes para llevar a cabo esta forma de segmentación son las redes totalmente convolucionales, ya que reportan los mejores desempeños en la detección de objetos. Sin embargo, la mayor parte de estas redes tienen alto costo computacional y requieren de computadoras costosas, por lo que han surgido recientemente modelos basados en estas redes, pero con baja complejidad en cálculos para que las aplicaciones de segmentación semántica se puedan implementar desde sistemas embebidos. Por lo tanto, para contribuir con este esfuerzo, se presenta en este artículo un análisis detallado las redes Enet, Mobilenet v2, ERFNet y ESPNet v2, las cuales son redes populares en la literatura que se pueden correr desde un sistema embebido. Con base en los resultados, se concluye que los métodos que reemplazan la convolución regular por factorizaciones como la convolución separada en profundidad y convoluciones dilatadas con diversas ramas y el uso de otras estrategias como convoluciones saltadas e interpolaciones articuladas reducen el costo computacional comparando las métricas generadas por cada red como la huella de memoria, la precisión y el tiempo que tarda en segmentar una sola imagen.
Refactoring Techniques for Improving Software Quality: Practitioners’ Perspectives
Authors: Almogahed Abdullah , Omar Mazni
Published: September 2021

Refactoring is a critical task in software maintenance and is commonly applied to improve system design or to cope with design defects. There are 68 different types of refactoring techniques and each technique has a particular purpose and effect. However, most prior studies have selected refactoring techniques based on their common use in academic research without obtaining evidence from the software industry. This is a shortcoming that points to the existence of a clear gap between academic research and the corresponding industry practices. Therefore, to bridge this gap, this study identified the most frequently used refactoring techniques, the commonly used programming language, and methods of applying refactoring techniques in the current practices of software refactoring among software practitioners in the industry, by using an online survey. The findings from the survey revealed the most used refactoring techniques, programming language, and the methods of applying the refactoring techniques. This study contributes toward the improvement of software development practices by adding empirical evidence on software refactoring used by software developers. The findings would be beneficial for researchers to develop reference models and software tools to guide the practitioners in using these refactoring techniques based on their effect on software quality attributes to improve the quality of the software systems as a whole.

BACKGROUND. Particularly dangerous coronavirus disease (COVID-19) continues to be one of the urgent problems of mankind. Researchers around the world have noted that in the third wave of the COVID-19 pandemic, the disease became more aggressive. Physicians more often began to pay attention to the occurrence of progressive lung degradation, in particular bullous-emphysematous changes in the lungs, and in those patients who did not have a history of chronic lung disease. Due to the fact that in the acute phase of coronavirus infectious computed tomography (CT) of the chest according to the national protocol is not required, the timing of this complication remains unknown.

OBJECTIVE. To study the timing of the onset of disappearing lung syndrome as one of the complications of communityacquired pneumonia of viral etiology (COVID-19) and to demonstrate on clinical observations according to CT.

MATERIALS AND METHODS. A group of patients referred for treatment to the SI “National institute of phthisiology and pulmonology named after F.G. Yanovsky of the NAMS of Ukraine”. Among the examined according to CT of the chest identified 21 patients (15 men and 6 women aged 24 to 67 years) with radiological signs of disappearing lung syndrome. Nine of them (7 men and 2 women aged 24 to 54 years) were treated at the institute during the acute period of the disease. Another 12 (8 men and 4 women aged 27 to 67 years) were referred to the institute from other medical institutions, where they were treated for community-acquired pneumonia of viral etiology (COVID-19) 3-4 months ago.

RESULTS AND DISCUSSION. CT analysis of the chest in 21 patients with disappearing lung syndrome showed that 9 (42,9 %) of them were diagnosed with bullous-emphysematous changes in the acute period of the disease – from 1 to 2 months, and in 12 (57,1 %) – in the postpartum period, in the period from 3 to 4 months. At the same time, patients had difficulty breathing, coughing, no significant improvement in general condition after previous inpatient treatment. Three of 12 patients noted deterioration of the general condition.

CONCLUSIONS. In severe patients with community-acquired pneumonia of viral etiology (COVID-19), a progressive pulmonary degradation syndrome with the formation of bullous-emphysematous changes can occur both in the acute period of the disease and develop or progress in the postpartum period (after 3-4 months after inpatient treatment). CT of the chest should be performed in all patients after inpatient treatment and elimination of acute respiratory distress syndrome, which will allow timely diagnosis of changes in lung architecture and complications of the disease.

Published: September 2021

The study was conducted to determine the performance and attitudes towards reading and writing of Grade 12 students in public schools of Cabagan, Isabela. There were 244 students involved in the study. Stratified random sampling was used in selecting the participants of the study. A quantitative research method was used in the study to determine performance and attitudes towards reading and writing. Frequency counts, percentage scores, the arithmetic mean, and Kendall’s Rank Correlation Tau was used to describe and analyze the data in the study. The findings of the study revealed that students' reading and writing performance were poor. However, their attitudes toward reading and writing were positive. Hence, the study demonstrated that there is a significant correlation between students’ attitudes and their reading and writing performance. Thus, the study supports DepEd’s "SulongEdukalidad" in creating programs to enhance learners' reading mastery and sustain its basic goal of producing quality learners enhanced by quality education. Language teachers should also be engaged and exposed to training to handle weak foundations of learners in basic academic (reading and writing) skills.

Pedagogical implications for ESL (English as a second language) and EFL (English as a foreign language) and researchers are offered in the light of these results.
Global Perspectives on Smart-Power Strategy in International Arena: Critical Discovery into Philosophy of Clausewitz and Sun Tzu from Strategic Implications
Authors: Bao Barack Lujia
Published: September 2021

Within the military discipline, the doctrine from Carl von Clausewitz and Sun Tzu can be framed as the ones among the most influential strategy-based philosophical domains. Carl von Clausewitz’s theoretical framework of consolidation of all powers and strategic obliteration of all forces of the opponents and rivals seems not uncommon in analysing the scenarios of international power competition and contest. On the contrary, Sun Tzu (around 545B.C.-470B.C.), the ancestral Chinese military strategist during the Spring and Autumn Period, put forward the complete distinctive strategic conception of optimum winning without engaging in any fight, which meanwhile plays a more epistemologically productive, thought-provoking role in utilising smart power strategy in a complex, evolving international arena where hard power alone has been of no avail to keep a dominantly advantageous position. Sequentially, it is indispensable for strategists to conduct in-depth exploration into the role of smart power through abstractly inheriting the consequential philosophical implications from Sun Tzu and Clausewitz as a distinctive strategy-building element and eclectically and rationally combine, enliven and hierarchise their implicit ties with an authentic world matrix that it is hard to empirically theorise and accurately quantify. Through deductive-analysis approaches and case studies of the US (a dominant power in relative terms over the long run), China (the second-largest economic power thus far) and India (a rising power in BRICS), the primary purpose of this paper seeks to dialectically explore an implicit dyadic nexus between 1) the philosophical implications for Sun Tzu and those for Clausewitz and 2) the nature and implementation of smart power strategy ranging from the perspectives of historical origin and international context. It can be argued that the philosophical standpoint of smart power strategy bears historical merits that the principal arguments from Clausewitz and Sun Tzu somehow generated. This paper-based on existential research findings meanwhile prognosticates that the strategic implementation of smart-power strategy, which tends to be highlighted worldwide in the foreseeable future, will advance in a world of multipolarisation instead of bipolarity and strategic co-opetition (i.e. cooperation and competition combined) will grow as an alternative widespread international phenomenon and trajectory that complicates the magnetism, flexibility and unpredictability of how a broad definition of national strength would influence the international structure and international standing.

Una falla geológica de fallas raciales : el sur norteamericano en Piri Thomas y Manuel Zapata Olivella.
Authors: Maddox John
Published: September 2021

En los años 1940 dos afro-latinos hemisféricos, el afro-puertorriqueño Piri Thomas y el afro-colombiano Manuel Zapata Olivella, viajaron al Sur durante la época de las leyes discriminatorias Jim Crow y los linchamientos de negros. ¿Por qué se pusieron en peligro? Mi respuesta adapta el concepto de los “movimientos continentales” inter-americanos del crítico John D. “Río” Riofrío al contexto de Jim Crow para mostrar que el Sur norteamericano era una “zona catastrófica” a la cual viajaron estos escritores en su juventud para fortalecer sus identidades afro-latinas y su compromiso con la comunidad. Las confrontaciones de estos autores y sus protagonistas con la zona de desastre del Sur son relevantes mientras América experimenta el Nuevo Jim Crow y la época de Trump.

Published: September 2021

Objective: It has been difficult to establish specific subtypes of obstructive sleep apnea (OSA) due to the heterogeneous nature of the disor- der. Previous studies have attempted to exact clinical subgroups or phenotypes of the disorder. However, the psychiatric impact of OSA has been often overlooked, and thus, this study used cluster analysis to examine subgroups of OSA incorporating mood states.Methods: This study is comprised of 346 adult OSA patients (apnea-hypopnea index, AHI≥5) who underwent polysomnography at Nowon Eulji Medical Center from January 2003 to November 2012. Their data also included validated self-report questionnaires that evaluate daytime sleepi- ness, sleep quality, morningness-eveningness, and mood states: Epworth Sleepiness Scale, Korean version of the Pittsburgh Sleep Quality In- dex (PSQI-K), Horne and Östberg Questionnaire, and Korean edition of Profile of Mood States (K-POMS), respectively. A K-means cluster analy- sis was performed to determine the optimal number of clusters and characteristics.Results: We identified three clusters: cluster 1, moderately symptomatic OSA with the least disturbed mood (n=166); cluster 2, severely symptomatic OSA not so disturbed mood (n=90); cluster 3, moderately symptomatic with highest disturbed mood (n=90). Cluster 1 had the lowest AHI and the lowest K-POMS total scores. Cluster 2, despite having the most severe OSA parameters, did not show mood disturbances. Cluster 3 had the highest K-POMS total scores and PSQI-K scores.Conclusion: Certain individuals with OSA are more likely to suffer from disturbed mood states without serious OSA indices. Psychiat- ric manifestations should also be considered when determining the severity of the disorder.

Effects of Elevated Temperatures on the Properties of High Strength Cement Paste Containing Silica Fume
Authors: Abdelmelek Nabil , Lublóy Éva
Published: September 2021

High strength concrete (HSC) production is worldwide increased and gradually replacing the normal strength concrete (NSC). The cement matrix of concrete is the essential part that governs the behavior and strength of concrete. Several researchers have focused on the performance of hardened cement paste (HCP) at ambient temperature such as using different types of supplementary cementitious materials (SCM). However, the performance of HCP after exposure to elevated temperatures requires further evaluation. The present study investigates the influence of different replacements of silica fume (SF) to cement and different water/binder ratios (w/b) on the compressive strength of HCP before and after exposure to elevated temperatures. Eighteen mixes have been prepared and tested. Results of compressive strength tests at ambient temperature were ranged from 58 to 102 MPa depending on the difference of w/b. Furthermore, a new method has been adopted for comparing the responses of HCP at elevated temperatures "heat endurance". Results showed that using SF enhances the residual compressive strength of HCP after exposure to elevated temperatures due to the pozzolanic reaction and the filler contribution. Mixes containing 6%, 12%, and 15% of SF have shown the highest relative residual compressive strength values for 0.30, 0.35, and 0.40 w/b, respectively. Consequently, the results were significantly affected by changing the w/b ratio. Finally, different measurement techniques were provided to support the work, including Thermo-Gravimetric (TG), Computed Tomography (CT), and Scanning Electron Microscope (SEM) analysis to characterize the loss of mass, porosity, and micro-structure alteration of HCP.

Integrated teaching is teaching in which the educational contents of subjects are interconnected. Connections can be discussed in a specialized integrated subjects e.g., Integrated science. Integrated science is a subject that connects knowledge from chemistry, biology, physics, geography, and geology. One topic is discussed from a different point of view, and students should transform their theoretical knowledge in practice. Worksheets can serve as a teaching material that can provide help to students as well as teachers and guide students on their path to knowledge. But how should a worksheet look like and how should the tasks be designed? This contribution describes a suggested method for making a worksheet for integrated (science) teaching that we call CCCTER. CCCTER is abbreviation for choose, connect, create, try, evaluate, remade. The method implements the national Framework education program for secondary general education (grammar schools) in the process of making the tasks. The principles choose, connect, and create are demonstrated. It provides a sample task of a worksheet for integrated (science) teaching.

Cardiovascular (CV) toxicities of the Bruton tyrosine kinase (BTK) inhibitor ibrutinib may limit use of this effective therapy in patients with chronic lymphocytic leukemia (CLL). Acalabrutinib is a second-generation BTK inhibitor with greater BTK selectivity. This analysis characterizes pooled CV adverse events (AE) data in patients with CLL who received acalabrutinib monotherapy in clinical trials (clinicaltrials gov. Identifier: NCT02029443, NCT02475681, NCT02970318 and NCT02337829). Acalabrutinib was given orally at total daily doses of 100–400 mg, later switched to 100 mg twice daily, and continued until disease progression or toxicity. Data from 762 patients (median age: 67 years [range, 32–89]; median follow-up: 25.9 months [range, 0–58.5]) were analyzed. Cardiac AE of any grade were reported in 129 patients (17%; grade ≥3, n=37 [5%]) and led to treatment discontinuation in seven patients (1%). The most common any-grade cardiac AE were atrial fibrillation/flutter (5%), palpitations (3%), and tachycardia (2%). Overall, 91% of patients with cardiac AE had CV risk factors before acalabrutinib treatment. Among 38 patients with atrial fibrillation/flutter events, seven (18%) had prior history of arrhythmia or atrial fibrillation/flutter. Hypertension AE were reported in 67 patients (9%), 43 (64%) of whom had a preexisting history of hypertension; no patients discontinued treatment due to hypertension. No sudden cardiac deaths were reported. Overall, these data demonstrate a low incidence of new-onset cardiac AE with acalabrutinib in patients with CLL. Findings from the head-to-head, randomized trial of ibrutinib and acalabrutinib in patients with highrisk CLL (clinicaltrials gov.

A functional and process flow diagram of an energy-saving floor heating panel using a thermoelectric assembly operating in a heat pump mode has been developed. The technique and calculation of the main heat-and-power parameters of this installation are presented. Studies of a working prototype of a floor heating panel, which have shown the high energy efficiency of the installation being developed, have been performed. It is shown that energy saving is about 15% in comparison with the serially used equipment for local heating of young animals.
COVID-19 Associated Multisystem Inflammatory Syndrome in Children (MIS-C): A New Pediatric Alert
Authors: Sharmin Shova Shamima , Islam Mohammad Imnul
Published: September 2021

Multisystem inflammatory syndrome in children (MIS-C), also termed pediatric multisystem inflammatory syndrome (PMIS) temporally associated with coronavirus disease-2019 (COVID-19) is rare but an emerging alarming condition. Though the exact pathogenesis is unknown, COVID-19 can trigger the condition directly or indirectly via immune complex mediated or antibody-dependent enhancement. Patients with MIS-C can present with persistent fever and a constellation of symptoms including hypotension, multiorgan involvement and elevated inflammatory markers. Presentations of MIS-C have overlapping features of Kawasaki disease (KD), toxic shock syndrome (TSS) and Kawasaki disease shock syndrome. Age of presentation, features of shock and more predilections for myocardial dysfunction can distinguish MIS-C from Kawasaki disease. Early recognition is essential, followed by prompt admission to the hospital for specialist attention. Admission to a pediatric intensive unit is mandatory for children with hemodynamic instability (shock, arrhythmia), significant respiratory compromise, or other potentially life-threatening complications. It is also necessary to maintain an appropriate follow-up schedule to observe the long-term outcome. The prognosis of PMIS/ MIS-C is uncertain, given that it is a new clinical entity and understanding of the disease is still evolving.

ANALYZING RELIGION AND TRUST RELATIONSHIP FROM TURKISH PERSPECTIVE
Authors: YILMAZ Murat
Published: September 2021

This article investigates the relationship between religion and trust using the Turkish sample from the World Values Surveys (WVS). This study focuses on a majority Muslim nation that has been institutionally secular and democratic for more than 90 years. This study explores the longitudinal relationship between religion and trust from 2001 to 2012, a period of significant social transformation.

Over this period, the effects of religion’s covariates on trust outcomes are consistent. However, the findings explore mix supports to the existing literature. Namely, the effects of religious affiliation and behaviour vary on trust outcomes. This study also investigates possible correlations between trust components, and the results do not support the previous findings.
Real-time object detection technology in railway operations

Published: September 2021

Development of new technology to enhance train operability, in particular during manual driving by real-time object detection on track, is one of the rising trends in the railway industry. The function of object detection can provide train operators with reminder alerts whenever there is an object detected close to a train, e.g. a defined distance from the train. In this paper, a two-stage vision-based method is proposed to achieve this goal. At first, the Targets Generation Stage focuses on extracting all potential targets by identifying the centre points of targets. Meanwhile, the Targets Reconfirmation Stage is further adopted to re-analyse the potential targets from the previous stage to filter out incorrect potential targets in the output. The experiment and evaluation result shows that the proposed method achieved an Average Precision (AP) of 0.876 and 0.526 respectively under typical scenario sub-groups and extreme scenario sub-groups of the data set collected from a real railway environment at the methodological level. Furthermore, at the application level, high performance with the False Alarm Rate (FAR) of 0.01% and Missed Detection Rate (MDR) of 0.94%, which is capable of practical application, was achieved during the operation in the Tsuen Wan Line (TWL) in Hong Kong.
Ocean acidification modifies the impact of warming on sediment nitrogen recycling and assimilation by enhancing the benthic microbial loop
Authors: Simone MN , Oakes JM , Schulz KG , Eyre BD
Published: September 2021

Nitrogen that has been recycled in the benthos supports high rates of primary and secondary production in estuaries. However, little is known about the effect of future climate on benthic nitrogen recycling and assimilation. An ex situ core incubation was used to assess the impact of combinations of warming (8°C range) and ocean acidification (OA) (i.e. increased pCO2 and decreased pH) on ammonium (NH4+) and nitrate/nitrite (NOx) fluxes and 15N-nitrate assimilation in shallow unvegetated estuarine sediments. Dissolved inorganic nitrogen (DIN = NH4+ + NOx) fluxes were significantly affected by the interaction of warming and OA, highlighting the importance of considering combined stressor treatments when investigating ecosystem responses to future climates. Warming alone increased DIN efflux from the sediments. At current mean ambient temperatures (23°C) and below (Δ-3°C), OA significantly increased DIN effluxes, but there was little to no effect of OA on DIN fluxes at warmer temperatures (Δ+3°C and Δ+5°C). OA reduced the 15N assimilation/retention of the sediments across all temperatures, suggesting that nitrogen retention in bacterial biomass was reduced, despite OA also increasing primary productivity. As such, under the projected future climate of ~3°C warming and doubling of pCO2 (~1000 µatm), unvegetated estuarine sediments are likely to have a more rapid turnover of DIN driven by greater microphytobenthos production and recycling.
