Authors: Fazekašová Danica , Fazekaš Juraj , Štofejová Lenka
Published: November 2021

The focus of this work is on the evaluation of selected water quality indicators as per the applicable regulations, taking into account European and national legislation and the evaluation of the risk of contamination of surface waters with toxic elements using the contamination factor (Cfi) and the degree of pollution (Cd). The studied area of Slovinky is an important ore region, with rich deposits of copper and silver ores that have been mined for centuries. One of the most important remnants of mining activities in this area is the Slovinky tailing impoundment. The sludge pond area has an area of 15 ha, and the height of the dam is 113 m above sea level, which makes the sludge pond one of the tallest water structures in Slovakia. The Slovinský creek was monitored in the years 2010, 2011, and 2019 at five sampling points, which were selected to map the entire length of the water flow from the source to the estuary to the river Hornád. Risk elements (As, Cu, Cd, and Fe) and physicochemical parameters (such as temperature, dissolved oxygen concentration, conductivity, resistivity, salinity, total dissolved solids, NaCl, redox potential, and pH) were included in this study and evaluated according to applicable regulations, taking into account European legislation (Act No. 269/2010 Coll., guideline value WHO 2011). The results of the experimental studies showed that the highest values of As and Cu were measured at the site where drainage waters from the Slovinky tailing impoundment and mining water of the Alžbeta shaft flow into the creek. The concentration of As exceeded the limit value by up to 31 times and the concentration of Cu 16.8–134.5 times. At the same time, the highest values of conductivity, salinity, total dissolved solids, and NaCl were found, and there was no acidification of water at the site that had the highest pollution. Water contamination was assessed based on Cfi and Cd; our findings showed that the surface water from the site of contamination, along the entire length of the stream, was very highly contaminated with risk elements in the order of As > Fe > Cu, and the level of contamination decreased with distance from the site of contamination. Our research shows that seepage of toxic substances from sludge ponds and abandoned mines has caused the requirements for the quality of surface water of the Slovinský creek not to be met. In connection with mining activities, surface streams act as a transport medium through which other components of the environment can be polluted.
Estimating Regional Evapotranspiration Using a Satellite-Based Wind Speed Avoiding Priestley–Taylor Approach
Authors: Sun Jingjing , Wang Wen , Wang Xiaogang , Huang Dui
Published: November 2021

Wind speed (u) is a significant constraint in the evapotranspiration modeling over the highly heterogeneous regional surface due to its high temporal-spatial variation. In this study, a satellite-based Wind Speed Avoiding Priestley–Taylor (WAPT) algorithm was proposed to estimate the regional actual evapotranspiration by employing a u-independent theoretical trapezoidal space to determine the pixel Priestley–Taylor (PT) parameter Φ. The WAPT model was comprehensively evaluated with hydro-meteorological observations in the arid Heihe River Basin in northwestern China. The results show that the WAPT model can provide reliable latent heat flux estimations with the root-mean-square error (RMSE) of 46.0 W/m2 across 2013–2018 for 5 long-term observation stations and the RMSE of 49.6 W/m2 in the growing season in 2012 for 21 stations with intensive observations. The estimation by WAPT has a higher precision in the vegetation growing season than in the non-growing season. The estimation by WAPT has a closer agreement with the ground observations for vegetation-covered surfaces (e.g., corn and wetland) than that for dry sites (e.g., Gobi, desert, and desert steppe).

Published: November 2021

The potential invasiveness of alien macroinvertebrate species in the Italian/Swiss hydrographic system of Lake Maggiore (NW Italy) was assessed through the Aquatic Species Invasiveness Screening Kit, a risk assessment tool developed for quantifying the impacts of alien species on the commercial, environmental, and species traits sectors. Data were collected using the databases provided by two regional environmental agencies in northern Italy (Lombardy and Piedmont regions) and by the governmental monitoring program of Switzerland, which were integrated with a systematic literature search on Google scholar and ISI Web of Science. In the assessment area, 16 macroinvertebrate invasive alien species were reported: nine mollusks, four decapods, and three amphipods. The species assessment indicated seven species with a high level of invasiveness: Procambarus clarkii, Faxonius limosus (formerly, Orconectes limosus) and Pacifastacus leniusculus, Dreissena polymorpha, Corbicula fluminea, Sinanodonta woodiana, and Pseudosuccinea columella. The results allow invasive species managers to understand which species to focus their monitoring on in the near future in order to track IAS movements and limit their spread within the hydrographic system and to provide the identification and refinement of concerted bilateral strategies aimed at limiting the impacts of these species. They also account for the implications of future climate change on the invasion potential of each species.

Long-Term Variation of Global GEOV2 and MODIS Leaf Area Index (LAI) and Their Uncertainties: An Insight into the Product Stabilities
Authors: Fang Hongliang , Wang Yao , Zhang Yinghui , Li Sijia
Published: November 2021

Leaf area index (LAI) is an essential climate variable that is crucial to understand the global vegetation change. Long-term satellite LAI products have been applied in many global vegetation change studies. However, these LAI products contain various uncertainties that are not been fully considered in current studies. The objective of this study is to explore the uncertainties in the global LAI products and the uncertainty variations. Two global LAI datasets—the European Geoland2 Version 2 (GEOV2) and Moderate Resolution Imaging Spectroradiometer (MODIS) (2003-2019)—were investigated. The qualitative quality flags (QQFs) and quantitative quality indicators (QQIs) embedded in the product quality layers were analyzed to identify the temporal anomalies in the quality profile. The results show that the global GEOV2 (0.042/10a) and MODIS (0.034/10a) LAI values have steadly increased from 2003 to 2019. The global LAI uncertainty (0.016/10a) and relative uncertainty (0.3%/10a) from GEOV2 have also increased gradually, especially during the growing season from April to October. The uncertainty increase is larger for woody biomes than for herbaceous types. Contrastingly, the MODIS LAI product uncertainty remained stable over the study period. The uncertainty increase indicated by GEOV2 is partly attributed to the sensor shift in the product series. Further algorithm enhancement is necessary to improve the cross-sensor performance. This study highlights the importance of studying the LAI uncertainty and the uncertainty variation. Temporal variations in the LAI products and the product quality revealed herein have significant implications on global vegetation change studies.

Published: November 2021

Background: In the modern era of tremendous automation in analytical processes, reporting errors have been reduced significantly. Therefore, the focus has been shifted to identifying the extra analytical causes of errors in the laboratory. Objectives: This study aimed to audit major clinical decisions affecting quality indicators (i.e., reporting errors and error prevention) by adhering to ISO 15189 (2012) and National Accreditation Board for Testing and Calibration Laboratories (NABL) (112) requirements. Methods: The records of the reporting errors were maintained from the biochemistry section of the central clinical laboratory (CCL) and analyzed based on the aim of this study. Then, the root cause analysis was performed, and the data was collected and audited from November 2015 to July 2020. Results: The total number of reporting errors between the mentioned periods were 132, with an incidence of 1 error per 384 processed samples on the day of observing the reporting error. In general, 22 (16.67%), 16 (12.12%), and 94 (71.21%) cases were pre-analytical, analytical, and post-analytical errors, respectively. The incidence of the post-analytical error was noted to be more since they were all typographical errors. Conclusion: Overall, transcriptional or typographical errors were found to be the main causes of reporting errors. In our clinical laboratory, we are attempting to minimize these errors by pre-validating the results by senior technicians and faculty prior to the typing and approval. These avoidable errors can be minimized by the continuous training of laboratory staff. Up-gradation to automated data collection information management systems are of great hope for preventing such errors.
Clinical and laboratory differences between extended-spectrum β-lactamase-positive and extended-spectrum β-lactamase-negative bacteria in febrile urinary tract infection in pediatrics
Authors: Kahbazi Manijeh , Yousefichaijan Parsa , Habibi Danial , Nejabat Somaie , Najmi Amirreza , Karimi Fateme
Published: November 2021

Introduction: The prevalence of urinary tract infections (UTIs) due to extended-spectrum beta-lactamase (ESBL)-producing bacteria is rising, which needs more potent antibiotics, such as carbapenems. Objectives: To evaluate the clinical and laboratory differences between ESBL-positive and ESBL-negative bacteria in febrile UTI in children between one month to seven years to indicate prognostic parameters for ESBL+ UTI and to suggest appropriate antibiotic treatment. Patients and Methods: This cross-sectional study investigated 282 patients diagnosed with the first febrile UTI. The participants were assigned to ESBL-positive and ESBL-negative UTI groups. The groups were compared based on their clinical and laboratory characteristics and outcomes; the infant group was assessed separately (with the onset age of <3 months). Results: The ESBL UTI was detected in 10.2% of the cases with a history of more frequent hospitalization (P=0.002), longer hospitalization (P=0.04), higher recurrence rate (P=0.003), and more red blood cell count in urine analysis findings (P=0.02). In the antimicrobial susceptibility assay, the ESBL-positive UTI group indicated resistance to third-generation cephalosporins; nevertheless, 93.1% of the cases responded clinically. The infant group showed 13% of the patients with ESBL-positive UTI that was correlated with a history of longer preonset hospital stay (P=0.001), elevated C-reactive protein (CRP) concentration (P=0.002), and elevated recurrence rate (P=0.03), compared to the older group. Conclusion: The ESBL UTI should be further considered due to the resulted recurrence rate. The antimicrobial sensitivity assay indicated resistance to third-generation cephalosporins; however, these drugs are applied as the first choice due to the high response rate. Aminoglycosides are applicable as second choice drugs prior to initiating the use of carbapenems, if third-generation cephalosporins did not indicate bactericidal impacts on ESBL UTI.

Published: November 2021

Introduction: One of the most common nosocomial infections is urinary tract infection (UTI) which more commonly occurs in patients with urethral catheter. Objectives: The aim of this study is to compare the incidence rate of catheter-associated bacteriuria (CRB) and UTI between sheathed designed catheters versus other methods of urinary drainage. Patients and Methods: In this randomized double-blind controlled trial, 150 male patients, who needed urethral catheter, were randomly assigned into three groups; condom bag, designed sheath catheter and traditional Foley catheter. The midstream urine samples were sent to laboratory to evaluate bacteriuria immediately after catheter insertion, upon catheter removal and after two weeks consequently. Results: The mean age of patients was 51.28 ± 14.12 years. The frequency of bacteriuria in patients was 19 (38%), 10 (20%) and 10 (20%) in the traditional catheter, condom bag and sheathed designed catheter, respectively, which was strongly significant (P<0.001). Conclusion: The frequency of bacteriuria in the patients with designed sheathed catheter was significantly less than the traditional catheter. Therefore, using the designed catheter in short-term may be safer in the patients. Trial registration: The trial was registered in the Thai Clinical Trials Registry (identifier: TCTR20200703002; http://www.clinicaltrials.in.th/index.php?tp=regtrials & menu=trialsear ch & smenu=fulltext & task=search & task2=view1& id=6443).

ABSTRACTThe current international business transaction activity is not difficult, with the advancement of technology, the world provides ample opportunities and opportunities for the international community to make connections between them.. International business transactions are private law studies, where in private law the law provides wider opportunities for each party to make, agree and execute the clauses they make. However, it can not be said that in order to carry out such business activities, the parties must carefully understand and understand the legal norms in the countries of the opposing parties. This will greatly affect the implementation of the agreement. For that reason it is necessary for researchers to clarify the study of legal protection of international business transactions in the era of free trade.The following issues are Legal Principles of International business transactions in the era of free trade and Legal Certainty on International Business transactions. The method used is normative legal research.This research produces the Principles of law of international business transactions can be found in the rules of international treaty law which regulates the provisions of international business transactions. The provisions of the international convention on the Contracts for the International Sale of Goods (CISG) and the UNIDROIT Principle of International Contracts of 1994 and Legal certainty in international business contracts can be seen from the legal source of international business contracts. Not surprisingly, when different business actors of citizenship conduct international business transactions, they will consent to law enforcement of one of the business actors. Keywords: Legal Protection, International Business Transactions, Free Trade

ABSTRACT The Kayan Mentarang National Park (KNPM) area located in the Heart of Borneo (HoB) in North Kalimantan lives various Dayak sub-tribes. They inhabit and keep the forest so that the forest remains safe and sustainable. Indigenous and tribal peoples who have customary forest areas in which their status of appointment as KMNP initially may receive, so that the process can continue in the inaugural process. But with the development of information and circumstances the situation was changed and now the indigenous people reject the pegat which will be doneThe legal issues that serve as the purpose of this paper are: the recognition of traditional rights of indigenous and tribal communities and the recognition of local wisdom in the management of Kayan Mentarang National Park. Using the normative juridical and customary law approaches that this method is expected to address the issue of law.The dynamics of the development of society and law can change the legal status of both government and customary law community to a legal fact. Forests as natural resources and the environment are constitutionally the government's obligation to regulate them. Inauguration of customary forest as a national park brings legal consequences to rights and obligations. Implementation of laws and regulations is limited by Human Rights. It is necessary to harmonize the law, so that both the interests of indigenous and tribal peoples, as the inhabitants as well as the natural resources, the environment, and the biodiversity as the interests of mankind are not mutually harmful. Keywords: Customary Law Community, Traditional Rights, National Park

Mode degeneracy and enhanced sensitivity in electrically injected PT-symmetric semiconductor laser with a quasi-high-order exceptional point
Authors: Chen Jingxuan , Wang Yufei , Fu Ting , Wang Xueyou , Dai Yingqiu , Zheng Wanhua
Published: November 2021

Exceptional points (EPs) can be exploited for a new generation of sensors. We propose an electrically injected parity-time (PT)-symmetric three-ridge semiconductor laser. By introducing the non-zero next-nearest-neighboring coupling coefficient to the Hamiltonian obtained by coupled mode theory, the results of eigenspectra match well with those of numerical simulation obtained by finite element method. Based on the introduced coupling coefficient, we develop our design and obtain a quasi-third-order EP. We analyze the eigenmode splitting vs perturbation strength at the EP, which proves that our design is rather sensitive to the external perturbation and possesses the potential to be applied as active high-sensitive sensors.

Проведений аналіз особливостей діагностики тромбоемболії легеневої артерії у пацієнтів на інфаркт міокарда. Визначено, що дані проведених досліджень вказують на існування специфічного гемодинамічного синдрому дисфункції правого шлуночка, що характеризується недостатнім його наповненням в результаті порушення здатності скорочуватися. Поєднання гемодинамічних ознак венозного типу застою з легеневою гіпертензією утруднюють діагностику тромбоемболії легеневої артерії у таких пацієнтів. Характер і механізм змін внутрішньосерцевої гемодинаміки у пацієнтів з різними формами інфаркту міокарда ще недостатньо вивчені і потребують подальшого детального дослідження. Помилки при КТ діагностиці можуть бути обумовлені ефектом часткового об’єму: накладенням периваскулярних м'яких тканин, зон розгалуження бронхів, і кровоносних судин, що йдуть не в вертикальному напрямку; артефактами, які обумовлені потоком крові і рухом, помилковими дефектами наповнення, обумовленими потоком крові.

Authors: Reddy G Aishwarya , Samad Mohammed Abdul , Siddalingappa Karjigi , Herakal Kallappa C
Published: November 2021

BACKGROUND: Dermatophytes are one of the most common fungal agents causing supercial skin infections. The prevalence of these infections varies from place to place and is more commonly associated with low socioeconomic status. AIMS AND OBJECTIVES: To isolate and identify the common dermatophytic species causing the infection and to know the efcacy of the antifungals commonly used against them. METHODS: One hundred and ten new cases, who consented for study were included. Skin scrapings were collected for direct microscopy by KOH and for fungal culture in Sabouraud 4% dextrose agar (SDA) with cycloheximide and dermatophyte test medium. Fungi were identied on the basis of their macroscopic and microscopic features with the help of lactophenol cotton blue staining and urease test. RESULTS: Of the 110 cases, 58 cases were KOH positive for fungal laments and culture positive for dermatophytes. Trichophyton was the predominant isolate (51 cases) with T. verrucosum being the commonest species (28 cases), followed by T. rubrum (16 patients), and T. mentagrophytes (7 cases). All species of Trichophyton were found to be most sensitive to systemic itraconazole and topical luliconazole amongst antifungals. CONCLUSIONS: Trichophyton species is the commonest organism causing fungal infections. Itraconazole and luliconazole are the most effective systemic and topical agents against them.
Multi-frame constrained block sparse Bayesian learning for flexible tactile sensing using electrical impedance tomography
Authors: Wang Xiaojie
Published: November 2021

In this paper, we presented a multi-frame constrained block sparse Bayesian learning (MFC-BSBL) reconstruction algorithm to tackle the challenge of poor-quality reconstruction images in electrical impedance tomography (EIT) for tactile sensing. The fundamental idea of MFC-BSBL is to explore the sparsity, intra-frame correlation, and inter-frame correlation of impedance distributions by extending the Bayesian inference framework. To verify the proposed algorithm, we conducted numerical simulations for different cases to identify one, multiple, round, and square targets. The simulation results demonstrated that this method can effectively detect the target positions and shapes by reducing artifacts and noise in the reconstructed images. To demonstrate the application of this approach to real EIT-based tactile sensing, we conducted real-contact detection experiments using the EIT tactile sensor system. Compared with traditional methods, the tactile sensor system using the MFC-BSBL algorithm can achieve accurate contact detection and significantly reduce artifacts and noise.
A Survey on Machine Learning and Deep Learning based Quality of Service aware Protocols for Software Defined Networks
Authors: Deva Sarma Hiren Kumar
Published: November 2021

Quality of Service (QoS) is one
of the most important parameters to be considered in computer networking and
communication. The traditional network incorporates various quality QoS
frameworks to enhance the quality of services. Due to the distributed nature of
the traditional networks, providing quality of service, based on service level
agreement (SLA) is a complex task for the network designers and administrators.
With the advent of software defined networks (SDN), the task of ensuring QoS is
expected to become feasible. Since SDN has logically centralized architecture,
it may be able to provide QoS, which was otherwise extremely difficult in
traditional network architectures. Emergence and popularity of machine learning
(ML) and deep learning (DL) have opened up even more possibilities in the line
of QoS assurance. In this article, the focus has been mainly on machine
learning and deep learning based QoS aware protocols that have been developed
so far for SDN. The functional areas of SDN namely traffic classification, QoS aware
routing, queuing, and scheduling are considered in this survey. The article presents
a systematic and comprehensive study on different ML and DL based approaches designed
to improve overall QoS in SDN. Different
research issues & challenges, and future research directions in the area of
QoS in SDN are outlined.

Published: November 2021

This study examined the effect of housing development on surface water quality in Enugu urban. The research design used for this study was experimental. A total of 11 samples of water were collected from the various selected site locations within the study area, in the three local government areas of Enugu urban. The water sample was collected with acid-washed and open dried polyethylene bottles, the samples were labeled according to their various rivers and streams, the polyethylene bottles were corked and were kept in ice-filled boxes, transported to PRODA for analysis. The major findings of the study showed that housing development in Enugu urban has a negative significant impact on water quality because Okwuosa river has an Organic matter level of 4.19 while WHO Limit is 2,9, therefore this aspect should be monitored for Okwuosa river in Enugu South. Other findings were Compared with the WHO standard and it showed that water quality deteriorates as housing development progresses. It is therefore the recommendation of the study that the housing authorities in Enugu state should institute measures to ensure that housing development does not compromise environmental quality and house owners and indeed all residents should be properly sensitized through environmental education on the dangers of abusing environmental standards.

Assessment of Medication Errors Among Anesthesia Clinicians in Saudi Arabia: A Cross-Sectional Survey Study
Authors: Aldossary Deemah Nassir , Almandeel Hussah Khalid , Alzahrani Jumanah Hashim , Alrashidi Hasnaa Obaid
Published: November 2021

Introduction

Anesthetic drugs are prepared and administrated without referral to the pharmacy or other medical departments. We aimed to assess the occurrence of anesthetic drug errors in Saudi Arabia. We also determined the contributing factors, reporting strategies, and clinicians' opinions of the preventive measures.

Methods

We conducted a cross-sectional web-based survey study using a validated tool. A total of 300 anesthesia clinicians completed the survey (146 anesthesiologists and 154 anesthesia technology specialists). We measured descriptive statistics to describe the demographic characteristics and performed inferential statistics to examine associations and differences.

Results

Sixty-nine percent of respondents had experienced an anesthetic drug error at least once in their career. The two primary factors that caused drug errors were haste (60.3%) and heavy workload (60.3%). On syringe labeling, 56.3% withdrew the drug then labeled the syringe, and 43.7% labeled the syringe then withdrew the drug. The chi-square test revealed that clinicians who labeled the syringe first then withdrew the drug made errors more frequently (p = 0.036). The test also showed that clinicians with less experience had committed more errors (p = 0.015). On reporting drug errors, 77.7% of respondents identified the fear of medicolegal issues as the most common barrier to reporting errors. Respondents believed that double-checking the medication and color-coded syringe labels were the most effective strategies to reduce errors (82% and 64%, respectively). The Mann-Whiney U test revealed significant differences between the two specialties about their opinions of the preventive measures.

Conclusions

There was a high occurrence rate of anesthetic drug errors in Saudi Arabia. Policymakers need to unify the syringe-labeling practice, and future research needs to focus on what makes a nonpunitive culture to encourage reporting errors.

The only thing that is expected in classroom learning activities is the achievement of learning objectives. One of the efforts to achieve the learning objectives is to always communicate with students, such as asking questions. This study aims to determine the query used by novice teachers during their micro-teaching practice in teaching Senior High School students. The theory of Lockhart (1994) is used in this research. Researchers used qualitative methods in processing data. The data obtained from the results of classroom observations with video zoom recording and documentation. The data sources for this study were taken from 10 novice teachers at one of the universities in Indonesia. The author took the data to find out what the novice teacher used during they were doing micro teaching classroom. As a result, the types of question that the teacher used are procedural question, convergent question, and divergent question. Then, the type of question that frequently uses is convergent question. The questions that novice teachers in teaching often use do not require high thinking.

Higher Order Thinking Skill (HOTS) is a demanded strategy to be applied in any teaching activities, including English teaching and learning process. This HOTS application offers attainable learning outcomes to the teachers when conducting teaching activities. Teachers are able to see how far students can learn based on cognitive, affective, and psychomotor aspect. However, there were problems which teachers found and challenged them to encounter the problems to keep the implementation of HOTS successful. This research was carried out to figure out teacher’s self-reflection on problems found and to determine decisions how to encounter them. In line to the research purpose, a qualitative research design was applied within interview and questionnaire. Furthermore, based on teacher’s reflection, it was revealed that during learning activities the students acted unmotivated and lack of confidence; they lacked English interest; and HOTs was not applied properly based on its stages. Then, decision making was established in terms of teaching strategies and lesson planning. In conclusion, despite the importance of creating HOTS to invite students to be creative and critical, problems still remained. Thus, self-reflection did assist teacher to analyze and figure out what teaching weaknesses are and imply to the HOTS application to improve teaching and learning process.
Imagined Communities and Identities in English as a Foreign Language (EFL) Learning: A Literature Review
Authors: Luong Vu Anh , Tran Thao Quoc
Published: November 2021

Imagined community and identity have been recognized as critical aspects in English language learning. Imagined community refers to the ideal community that learners wish to get engaged in, while imagined identity refers to the ideal self that language learners wish to become in the future. However, there is a scant research on these two notions in relation to English as a foreign language (EFL) learning. To that end, this paper aims to present the literature review of the contemporary theories on imagined communities and identities in EFL learning. It first discusses the imagined communities regarding the functions, community of practice, notions of imagined communities and concepts of imagined EFL classroom communities. It then scrutinizes imagined identities in terms of poststructuralists’ theory, English language learners’ identities, notion of imagined identity and EFL learners’ imagined identity. This paper is hoped to provide a timely and needed conceptual framework for other relevant constructs (e.g., English language learning investment) in English language learning.

A agricultura vem passando pela crise provocada pela pandemia da covid-19. Medidas necessárias para evitar a circulação do vírus têm afetado o mundo, em razão da paralisação de atividades produtivas e de serviços. A agricultura e suas cadeias produtivas são classifi cadas como serviços essenciais, paraque não haja ruptura no suprimento de alimentos. Isso implica que trabalhadores rurais, da agroindústria e da distribuição devem manter suas atividades, se adaptar ao contexto sanitário crítico e responder às demandas do mercado. Os efeitos desse cenário sobre o trabalho ainda não são claros, tendo em vista asituação inédita e de rápidas mudanças e medidas. Informações veiculadas pela grande mídia oferecem conteúdo que reflete o cenário atual sobre os efeitos da pandemia. O objetivo deste estudo é identificar os impactos da pandemia por covid-19 no trabalho em agricultura e cadeias produtivas, a partir da perspectiva da grande mídia nacional e internacional. A análise textual lexicométrica foi realizada em 28 notícias veiculadas pela grande mídia entre março e maio de 2020. Cinco principais impactos da covid-19 no trabalho foram identifi cados: saúde do trabalhador, disponibilidade de mão de obra, tempo de trabalho, ruptura da cadeia e mercado de trabalho. Tais impactos são estruturados em três níveis: propriedade agrícola, cadeia agrícola e economia e sociedade. As implicações econômicas e sociais desses impactos na agricultura e nas cadeias produtivas foram discutidas.

The ever increasing use of body-worn systems in the Internet of Things application such as needs better antenna subsystem designs compatible with its requirements. Several challenges limiting the performance of a body-worn system, from materials, and environmental conditions  to the effects of on body application and its hazards are discussed. As a test case, a flexible textile planar inverted-F antenna is presented and discussed. The choice of this topology is due to its simplicity in design and fabrication, relatively broad bandwidth and the presence of a rear ground plane, which minimizes the impacts of the human body on the antenna performance. It is designed on a felt substrate, whereas Aaronia-shield conductive textile is utilized as its  conductive parts (radiator, shorting wall and ground plane). The antenna performance are studied in two cases, first in free space and then in bent conditions in the close proximity to the human body. The influence of the relative humidity on the textile antenna performance is also investigated numerically. Simulated and measured results indicated good agreements. Finally, the proposed antenna is integrated with a transceiver module and evaluated on the body in practice. Its wireless link quality is assessed in an indoor laboratory.

Authors: Гаврилов Артем Дмитриевич
Published: November 2021

В статье поднимается проблема функционирования знаков препинания в русских, чувашских и английских медиатекстах на современном этапе. Автор утверждает, что анализ пунктуационного узуса необходимо проводить на материале сетевых газетных заголовков, поскольку в Интернете они являются главными речевыми единицами, формирующими информационную картину мира людей. Сетевые газетные заголовки концентрируют в себе языковые традиции и инновации, отражают тенденции пунктуационной практики цифрового общества, среди которых автор выделяет использование двоеточия в функции пояснения содержания, представленного в первой части бессоюзного сложного предложения, отсутствие вопросительного знака в конце вопросительного предложения, сочетание знаков препинания в предложении для усиления выразительности высказывания. Выявлено, что не все нормы и правила постановки знаков препинания рассматриваемых языков учитывают изменения в пунктуационном оформлении современных текстов. Автор приходит к выводу, что решение заявленной научной проблемы позволит уточнить новые функции и значения отдельных знаков препинания, переосмыслить их семантические и экспрессивные возможности, выявить национальные особенности и сформировать предложения для обновления свода правил пунктуации разноструктурных языков, а также внести существенный вклад в развитие теории медиа- и интернет-лингвистики, медиастилистики и, главным образом, сопоставительного языкознания.

The article raises the problem of the functioning of punctuation marks in Russian, Chuvash and English media texts at the present stage. The author argues that punctuation usage should be analyzed on the material of online newspaper headlines since on the Internet they are the main speech units that form the information picture of the world. Online newspaper headlines concentrate language traditions and innovations, reflect the trends of punctuation practice of the developing digital society. Among them, the author highlights the use of the colon in the function of explaining the content presented in the first part of a non-union complex sentence, the absence of the question mark at the end of the question, the combination of punctuation marks in the sentence to enhance the expressiveness. It is revealed that not all the norms and rules of punctuation marks of the considered languages take into account changes in the punctuation design of modern texts. The author comes to the conclusion that the solution to the stated scientific problem will allow us to clarify the new functions and meanings of individual punctuation marks, to rethink their semantic and expressive possibilities, to identify the national features of their use, to form proposals for updating the punctuation rules of different structural languages and to make a significant contribution to the development of the theory of media and Internet linguistics, media stylistics and, mainly, comparative linguistics.
