iBeacon Indoor Positioning Method Combined with Real-Time Anomaly Rate to Determine Weight Matrix
Authors: Guo Yu , Zheng Jiazhu , Zhu Weizhu , Xiang Guiqiu , Di Shaoning
Published: December 2020

This paper proposes an indoor positioning method based on iBeacon technology that combines anomaly detection and a weighted Levenberg-Marquadt (LM) algorithm. The proposed solution uses the isolation forest algorithm for anomaly detection on the collected Received Signal Strength Indicator (RSSI) data from different iBeacon base stations, and calculates the anomaly rate of each signal source while eliminating abnormal signals. Then, a weight matrix is set by using each anomaly ratio and the RSSI value after eliminating the abnormal signal. Finally, the constructed weight matrix and the weighted LM algorithm are combined to solve the positioning coordinates. An Android smartphone was used to verify the positioning method proposed in this paper in an indoor scene. This experimental scenario revealed an average positioning error of 1.540 m and a root mean square error (RMSE) of 1.748 m. A large majority (85.71%) of the positioning point errors were less than 3 m. Furthermore, the RMSE of the method proposed in this paper was, respectively, 38.69%, 36.60%, and 29.52% lower than the RMSE of three other methods used for comparison. The experimental results show that the iBeacon-based indoor positioning method proposed in this paper can improve the precision of indoor positioning and has strong practicability.

Published: December 2020

Cervical cancer is the fourth most common cancer in the world. Whole-slide images (WSIs) are an important standard for the diagnosis of cervical cancer. Missed diagnoses and misdiagnoses often occur due to the high similarity in pathological cervical images, the large number of readings, the long reading time, and the insufficient experience levels of pathologists. Existing models have insufficient feature extraction and representation capabilities, and they suffer from insufficient pathological classification. Therefore, this work first designs an image processing algorithm for data augmentation. Second, the deep convolutional features are extracted by fine-tuning pre-trained deep network models, including ResNet50 v2, DenseNet121, Inception v3, VGGNet19, and Inception-ResNet, and then local binary patterns and a histogram of the oriented gradient to extract traditional image features are used. Third, the features extracted by the fine-tuned models are serially fused according to the feature representation ability parameters and the accuracy of multiple experiments proposed in this paper, and spectral embedding is used for dimension reduction. Finally, the fused features are inputted into the Analysis of Variance-F value-Spectral Embedding Net (AF-SENet) for classification. There are four different pathological images of the dataset: normal, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), and cancer. The dataset is divided into a training set (90%) and a test set (10%). The serial fusion effect of the deep features extracted by Resnet50v2 and DenseNet121 (C5) is the best, with average classification accuracy reaching 95.33%, which is 1.07% higher than ResNet50 v2 and 1.05% higher than DenseNet121. The recognition ability is significantly improved, especially in LSIL, reaching 90.89%, which is 2.88% higher than ResNet50 v2 and 2.1% higher than DenseNet121. Thus, this method significantly improves the accuracy and generalization ability of pathological cervical WSI recognition by fusing deep features.

Published: December 2020

The elevated concentrations of various trace metals beyond existing guideline recommendations in water bodies have promoted research on the development of various electrochemical nanosensors for the trace metals’ early detection. Inspired by the exciting physical and chemical properties of nanomaterials, advanced functional nanocomposites with improved sensitivity, sensitivity and stability, amongst other performance parameters, have been synthesized, characterized, and applied on the detection of various trace metals in water matrices. Nanocomposites have been perceived as a solution to address a critical challenge of distinct nanomaterials that are limited by agglomerations, structure stacking leading to aggregations, low conductivity, and limited porous structure for electrolyte access, amongst others. In the past few years, much effort has been dedicated to the development of various nanocomposites such as; electrochemical nanosensors for the detection of trace metals in water matrices. Herein, the recent progress on the development of nanocomposites classified according to their structure as carbon nanocomposites, metallic nanocomposites, and metal oxide/hydroxide nanocomposites is summarized, alongside their application as electrochemical nanosensors for trace metals detection in water matrices. Some perspectives on the development of smart electrochemical nanosensors are also introduced.
PSANet: Pyramid Splitting and Aggregation Network for 3D Object Detection in Point Cloud
Authors: Li Fangyu , Jin Weizheng , Fan Cien , Zou Lian , Chen Qingsheng , Li Xiaopeng , Jiang Hao , Liu Yifeng
Published: December 2020

3D object detection in LiDAR point clouds has been extensively used in autonomous driving, intelligent robotics, and augmented reality. Although the one-stage 3D detector has satisfactory training and inference speed, there are still some performance problems due to insufficient utilization of bird’s eye view (BEV) information. In this paper, a new backbone network is proposed to complete the cross-layer fusion of multi-scale BEV feature maps, which makes full use of various information for detection. Specifically, our proposed backbone network can be divided into a coarse branch and a fine branch. In the coarse branch, we use the pyramidal feature hierarchy (PFH) to generate multi-scale BEV feature maps, which retain the advantages of different levels and serves as the input of the fine branch. In the fine branch, our proposed pyramid splitting and aggregation (PSA) module deeply integrates different levels of multi-scale feature maps, thereby improving the expressive ability of the final features. Extensive experiments on the challenging KITTI-3D benchmark show that our method has better performance in both 3D and BEV object detection compared with some previous state-of-the-art methods. Experimental results with average precision (AP) prove the effectiveness of our network.
Vicarious Radiometric Calibration of Ocean Color Bands for FY-3D/MERSI-II at Lake Qinghai, China

Published: December 2020

To calibrate the low signal response of the ocean color (OC) bands and test the stability of the Fengyun-3D (FY-3D)/Medium Resolution Spectral Imager II (MERSI-II), an absolute radiometric calibration field test of FY-3D/MERSI-II at the Lake Qinghai Radiometric Calibration Site (RCS) was carried out in August 2018. The lake surface and atmospheric parameters were mainly measured by advanced observation instruments, and the MODerate spectral resolution atmospheric TRANsmittance algorithm and computer model (MODTRAN4.0) was used to simulate the multiple scattering radiance value at the altitude of the sensor. The results showed that the relative deviations between bands 9 and 12 are within 5.0%, while the relative deviations of bands 8, and 13 are 17.1%, and 12.0%, respectively. The precision of the calibration method was verified by calibrating the Aqua/Moderate-resolution Imaging Spectroradiometer (MODIS) and National Polar-orbiting Partnership (NPP)/Visible Infrared Imaging Radiometer (VIIRS), and the deviation of the calibration results was evaluated with the results of the Dunhuang RCS calibration and lunar calibration. The results showed that the relative deviations of NPP/VIIRS were within 7.0%, and the relative deviations of Aqua/MODIS were within 4.1% from 400 nm to 600 nm. The comparisons of three on-orbit calibration methods indicated that band 8 exhibited a large attenuation after launch and the calibration results had good consistency at the other bands except for band 13. The uncertainty value of the whole calibration system was approximately 6.3%, and the uncertainty brought by the field surface measurement reached 5.4%, which might be the main reason for the relatively large deviation of band 13. This study verifies the feasibility of the vicarious calibration method at the Lake Qinghai RCS and provides the basis and reference for the subsequent on-orbit calibration of FY-3D/MERSI-II.
Hierarchical Suppression Based Matched Filter for Hyperspertral Imagery Target Detection
Authors: Gao Ce , Wu Yiquan , Hao Xiaohui
Published: December 2020

Target detection in hyperspectral imagery (HSI) aims at extracting target components of interest from hundreds of narrow contiguous spectral bands, where the prior target information plays a vital role. However, the limitation of the previous methods is that only single-layer detection is carried out, which is not sufficient to discriminate the target parts from complex background spectra accurately. In this paper, we introduce a hierarchical structure to the traditional algorithm matched filter (MF). Because of the advantages of MF in target separation performance, that is, the background components are suppressed while preserving the targets, the detection result of MF is used to further suppress the background components in a cyclic iterative manner. In each iteration, the average output of the previous iteration is used as a suppression criterion to distinguish these pixels judged as backgrounds in the current iteration. To better stand out the target spectra from the background clutter, HSI spectral input and the given target spectrum are whitened and then used to construct the MF in the current iteration. Finally, we provide the corresponding proofs for the convergence of the output and suppression criterion. Experimental results on three classical hyperspectral datasets confirm that the proposed method performs better than some traditional and recently proposed methods.
Life-Cycle Assessment of Carbon Footprint of Bike-Share and Bus Systems in Campus Transit

Published: December 2020

Low-carbon transport system is desired for sustainable cities. The study aims to compare carbon footprint of two transportation modes in campus transit, bus and bike-share systems, using life-cycle assessment (LCA). A case study was conducted for the four-campus (College Ave, Cook/Douglass, Busch, Livingston) transit system at Rutgers University (New Brunswick, NJ). The life-cycle of two systems were disaggregated into four stages, namely, raw material acquisition and manufacture, transportation, operation and maintenance, and end-of-life. Three uncertain factors—fossil fuel type, number of bikes provided, and bus ridership—were set as variables for sensitivity analysis. Normalization method was used in two impact categories to analyze and compare environmental impacts. The results show that the majority of CO2 emission and energy consumption comes from the raw material stage (extraction and upstream production) of the bike-share system and the operation stage of the campus bus system. The CO2 emission and energy consumption of the current campus bus system are 46 and 13 times of that of the proposed bike-share system, respectively. Three uncertain factors can influence the results: (1) biodiesel can significantly reduce CO2 emission and energy consumption of the current campus bus system; (2) the increased number of bikes increases CO2 emission of the bike-share system; (3) the increase of bus ridership may result in similar impact between two systems. Finally, an alternative hybrid transit system is proposed that uses campus buses to connect four campuses and creates a bike-share system to satisfy travel demands within each campus. The hybrid system reaches the most environmentally friendly state when 70% passenger-miles provided by campus bus and 30% by bike-share system. Further research is needed to consider the uncertainty of biking behavior and travel choice in LCA. Applicable recommendations include increasing ridership of campus buses and building a bike-share in campus to support the current campus bus system. Other strategies such as increasing parking fees and improving biking environment can also be implemented to reduce automobile usage and encourage biking behavior.
Getting Young Drivers to Buckle Up: Exploring the Factors Influencing Seat Belt Use by Young Drivers in Malaysia
Authors: Ibrahim Ahmad Nazrul Hakimi , Borhan Muhamad Nazri , Mhd Yunin Nor Aznirahani
Published: December 2020

Many car drivers in Malaysia, especially young drivers, ignore the importance of wearing seat belts. This questionnaire study employed an extended version of the theory of planned behaviour (TPB) by including habit as a new construct to explain the factors influencing the behavioural intention and expectation of young Malaysian drivers to use seat belts. A total of 398 young drivers from the state of Selangor in Malaysia participated in this study. Analyses used a covariance-based structural equation modelling (CB-SEM) approach. The results showed that the variance, which indicates the intention of young Malaysian drivers to use seat belts (R2 = 0.76), is influenced by drivers’ habits and three basic constructs of the TPB (attitude, subjective norms, and perceived behavioural control). The basic TPB constructs have a direct and positive impact on the intention of young Malaysian drivers to use seat belts. Drivers’ habits have a positive and direct influence on their intention to use seat belts, and an indirect influence via the attitude and perceived behaviour control constructs. Drivers’ habits do not influence subjective norms. The authors recommend implementing effective measures to encourage Malaysian drivers to use seat belts and ensure sustainable traffic safety.
Barriers to Formal Help-Seeking Behavior by Battered Turkish Women According to Sociodemographic Factors
Authors: Keskin Abdulkadir , Karaman Filiz
Published: December 2020

Violence against women is a significant sociological problem that negatively affects society. Although violence against women is widespread worldwide, the help-seeking behavior of women exposed to violence remains underdeveloped. In this study conducted in Turkey, the formal help-seeking behavior of women exposed to violence was studied according to sociodemographic factors. Data were obtained from surveys on domestic violence against women from the Turkish Statistical Institute (TURKSTAT), which was held in 2008 and 2014. Chi-square and binary logistic regression analyses are used in this study. The dependent variable is determined as whether women who had experienced violence sought help from formal institutions. In order to explain the dependent variable, education, age group, region, and sociodemographic variables are used. According to the results, as the education level of women exposed to violence increases, help-seeking behavior through official means also increases. In addition, women with a personal income are more likely to seek formal help than those without, and the development of the sociocultural region inhabited affects the formal help-seeking behavior of women exposed to violence. Between 2008 and 2014, legal regulations on women’s rights in Turkey were seen to positively affect formal help-seeking behavior. Although the formal help-seeking behavior of women subjected to violence in 2014 increased significantly compared to 2008, this improvement is not sufficient.
Rethinking Sustainability Monitoring in the Arctic by Linking Resilience and Sustainable Development in Socially-Oriented Observations: A Perspective
Authors: Vlasova Tatiana , Petrov Andrey N. , Volkov Sergey
Published: December 2020

Monitoring of social-ecological systems dynamics and sustainability is of high importance in a rapidly changing Arctic. The goal of this essay is to discuss and articulate the principles for designing a suitable Arctic sustainability monitoring framework based on the convergence between resilience thinking and sustainable development paradigms. We propose to integrate sustainability monitoring into the socially-oriented observations (SOO) methodologies in order to design Arctic sustainability monitoring as a transdisciplinary participatory activity that results in both co-production of sustainability knowledge and building more sustainable and resilient Arctic social-ecological systems by enabling continuous observation and informed decision-making. Special attention is given to approaches for developing sustainability indicators to monitor trends in Arctic social-ecological systems. It is argued that sustainability monitoring is a valuable component of the Arctic sustainability knowledge system that integrates social and natural sciences and engages Indigenous, local, and traditional knowledge, entrepreneurship, education, and decision-making. Bringing together diverse knowledge systems is the primary route to collectively pursue sustainability in a holistic, polycentric, multifaceted, participatory, and knowledge-driven manner. Transdisciplinary SOO approaches and methods are specifically discussed.
MCNet: Multi-Scale Feature Extraction and Content-Aware Reassembly Cloud Detection Model for Remote Sensing Images
Authors: Yao Ziqiang , Jia Jinlu , Qian Yurong
Published: December 2020

Cloud detection plays a vital role in remote sensing data preprocessing. Traditional cloud detection algorithms have difficulties in feature extraction and thus produce a poor detection result when processing remote sensing images with uneven cloud distribution and complex surface background. To achieve better detection results, a cloud detection method with multi-scale feature extraction and content-aware reassembly network (MCNet) is proposed. Using pyramid convolution and channel attention mechanisms to enhance the model’s feature extraction capability, MCNet can fully extract the spatial information and channel information of clouds in an image. The content-aware reassembly is used to ensure that sampling on the network can recover enough in-depth semantic information and improve the model cloud detection effect. The experimental results show that the proposed MCNet model has achieved good detection results in cloud detection tasks.
Assessing the Influence of Compounding Factors to the Water Level Variation of Erhai Lake
Authors: Wu Huaxin , Wang Shengrui , Wu Tao , Yao Bo , Ni Zhaokui
Published: December 2020

Climate change and human activities cause lake water level (WL) fluctuations to exceed natural thresholds, with implications for the available water resources. Studies that explore WL change trends and the main driving forces that affect water level changes are essential for future lake water resource planning. This study uses the Mann–Kendall trend test method to explore the WL fluctuations trend and WL mutation in Erhai Lake (EL) during 1990–2019 and explore the main driving factors affecting water level changes, such as characteristic WL adjustments. We also use the principal component analysis to quantify the contribution of compound influencing factors to the water level change in different periods. The results showed that the WL rose at a rate of 47 mm/a during 1990–2019 but was influenced by the characteristic WL adjustment of EL in 2004 and the WL mutation in 2005. In 1990–2004, the WL showed a downtrend caused by the increase in water resource development and utilization intensity, and in 2005–2019, the WL showed an uptrend caused by the combined decrease in evaporation, outflow, and the increase in water supply for water conservancy projects. Additionally, the largest contributions of outflow to WL change were 19.34% and 21.61% in 1990–2019 and 1990–2004, respectively, while the largest contribution of cultivated area to WL change was 20.48% in 2005–2019, and it is worth noting that the largest contribution of climate change to WL change was 40.35% in 2013–2019. In the future, under the increase in outflow and evaporation and the interception of inflow, the WL will decline (Hurst exponent = 0.048). Therefore, planning for the protection and management of lakes should consider the impact of human activities, while also paying attention to the influence of climate change.
Large-Scale Particle Image Velocimetry for Estimating Vena-Contracta Width for Flow in Contracted Open Channels
Authors: Fakhri Alireza , Ettema Robert , Aliyari Fatemeh , Nowroozpour Alireza
Published: December 2020

This paper presents the findings of a flume study using large-scale particle velocimetry (LSPIV) to estimate the top-width of the vena contracta formed by an approach open-channel flow entering a contraction of the channel. LSPIV is an image-based method that non-invasively measures two-dimensional instantaneous free-surface velocities of water flow using video equipment. The experiments investigated the requisite dimensions of two essential LSPIV components—search area and interrogation area– to establish the optimum range of these components for use in LSPIV application to contractions of open-channel flows. Of practical concern (e.g., bridge hydraulics) is flow contraction and contraction scour that can occur in the vena contracta region. The study showed that optimum values for the search area (SA) and interrogation area (IA) were 10 and 60 pixels, respectively. Also, the study produced a curve indicating a trend for vena-contracta width narrowing with a variable ratio of approach-channel and contracted-channel widths and varying bed shear stress of approach flow.

Published: December 2020

The swelling effect in hydrogel bodies or sponge-like porous bodies (SPB) used in a specific stormwater storage concept of the down-flow type is considered. A macroscopic swelling model is proposed, in which water is assumed to penetrate into the hydrogel by diffusion described by diffusion equations together with a free-moving boundary separating the interface between the water and hydrogel. Such a type of problem belongs to the certain class of problems called Stefan-problems. The main objective of this contribution is to compare how the theoretical total amount of absorbed water is modified by the inclusion of swelling, when compared to the previously studied SPB devices analyzed only for the effect of diffusion. The results can be summarized in terms of the geometrical dimensions of the storage device and the magnitude of the diffusion coefficient D. The geometrical variables influence both the maximum possible absorbed volume and the time to reach that volume. The diffusion coefficient D only influences the rate of volume growth and the time to reach the maximum volume of stored water. The initial swelling of the hydrogel SPB grows with time (Dt) until the steady state is reached and the swelling rate approaches zero. In all the cases considered, the swelling in general increases the maximum possible absorbed water volume by an amount of 14%.

El Territorio en disputa: estrategias políticas y movimientos socioterritoriales
Authors: Halvorsen Sam
Published: December 2020

El territorio ha sido foco de análisis en diversas investigaciones. En gran parte de la literatura anglosajona ha sido conceptualizado como un resultado desde arriba de control del espacio, frecuentemente encarnado por el Estado. En contraste, los trabajos latinoamericanos suelen hacer hincapié en la potencia emancipadora de las luchas por el territorio en búsqueda de la autonomía. Este artículo avanza en una comprensión del concepto de territorio como estrategias superpuestas e intrincadas y, de esa manera, va más allá de los intentos por entenderlo como una dicotomía involucrada en procesos de construcción desde arriba (el Estado, por ejemplo) o desde abajo (los movimientos sociales). Para ello, examina literatura reciente sobre movimientos socioterritoriales –movimientos para los cuales la apropiación del espacio es el objetivo central de su estrategia– y explora algunas relaciones de poder. El artículo está organizado en tres secciones, las cuales corresponden a estrategias particularmente visibles de los movimientos socioterritoriales en las últimas décadas en la región.
Beriman Secara Autentik

Abstract: The main focus of this paper is to explain with theologically the phenomenon of life (Covid-19) which has recently become the unrest of mankind because it attacks all walks of life indiscriminately and gives a broad impact in various sectors of life including religious fields so that humans are forced to live in abnormal conditions and "leave" habits that have become a tradition. In a situation like this where humans are forced to suffer, religious people in particular Christianity will raise classic theodise questions, where is God? Why does He allow suffering to occur? Which then leads to the understanding that God is evil. Questions like these need to get an appropriate explanation using qualitative-descriptive methods with the aim of providing a biblical-theological description that God's position in disaster should be understood as a person who is present and suffers with humanity. He was in a disaster to strengthen and help mankind to cope with disaster, not as a God who was evil and who brought the plague of Covid-19. Humans must have authentic faith that is fully dependent on God in relation in Jesus Christ.

Dalam situasi seperti ini di mana manusia dipaksa untuk menderita, umat beragama secara khusus kekristenan akan melontarkan pertanyaan-pertanyaan teodise klasik, di mana Allah? Mengapa Ia membiarkan penderitaan terjadi? Yang kemudian berujung pada pemahaman bahwa Allah itu jahat. Pertanyaan-pertanyaan seperti ini yang kemudian penulis lihat perlu mendapat penjelasan yang tepat dengan menggunakan metode kualitatif-deskriptif dengan tujuan memberikan gambaran secara biblis-teologis bahwa posisi Allah dalam bencana sebaiknya dipahami sebagai pribadi yang hadir dan turut menderita bersama manusia. Ia ada dalam bencana untuk meneguhkan dan menolong manusia menghadapi bencana, bukan sebagai Allah yang jahat dan yang mendatangkan wabah penyakit Covid-19. Manusia harus beriman secara autentik yaitu bergantung sepenuhnya kepada Allah di dalam relasi dengan Yesus Kristus.

In the author's perspective, the public needs to get the right education to address the current conditions, because the characteristics of the corona virus are very fast spreading, so that it requires herd immunity to be able to fight the invisible object's ferocity. However, there seems to be a tendency to be apathetic towards covid 19 protocols. This is what the author later saw needs to get an appropriate explanation using qualitative-descriptive methods that aim to provide a theological understanding of human faith in the midst of the corona virus, a healthy lifestyle that must always be prioritized and build ugahari spirituality as a manifestation of faith that in the midst of non-disaster -in the current situation, God's blessing is always present and sufficient for humanity, through the utilization of local resources.

The properties of elastomers based on a combination of acrylonitrile-butadiene (NBR), ethylene-propylene (EPDM) rubbers and chlorosulfinated polyethylene (CSM) have been studied for the first time, which have been vulcanized by sulfur-free effective systems. The best balance in terms of frost resistance, heat resistance and fuel resistance is demonstrated by rubbers whose formulations are generally dominated by polar CSM and NBR with lower EPDM content (10-20 mas.h). The results of six-month field tests in tropical climate conditions demonstrate high resistance of elastomers to microorganisms. The obtained results stipulate the prospects of application of the created rubbers for operation in different climatic zones.

The effect of the molecular weight of polyvinylbutyral dissolved in phosphorus-containing dimethacrylate on the rheological characteristics of solutions and the properties of polymers based on them has been studied. It was found that the dynamic viscosity of solutions containing 3% PVB with a molecular weight of 43,000, 57,000, and 95,000 g/mol compared with the viscosity of the phosphorus-containing dimethacrylate itself significantly increases. Depending on the molecular mass of polyvinylbutyral, materials obtained under the conditions of photochemically initiated polymerization are characterized by an increase of the elastic modulus during static bending up to 53% at a constant level of oxygen index values.
Logística y transporte internacional:
Authors: Marinucci Elsa
Published: December 2020

Este trabajo describe la disrupción que la pandemia por COVID-19 causó a uno de los pilares de la logística internacional: el transporte. La respuesta inmediata a la pandemia fue el cierre de fronteras, afectando con ello al transporte internacional y, como consecuencia, a todo el movimiento, el almacenamiento y el flujo de mercancías entre países. Si bien el impacto del COVID-19 en la logística internacional se sintió por primera vez en China -debido al papel que este país desempeña en la fabricación mundial-, se extendió rápidamente por todo el mundo. Estas perturbaciones de la cadena de suministros generaron importantes aumentos de costos logísticos que afectaron aún más las ya debilitadas exportaciones de Argentina

Introducción. La hipoglucemia neonatal es el trastorno metabólico más frecuente y precoz del recién nacido, que puede causar desde irritabilidad transitoria hasta estados de convulsión, apnea y muerte. Objetivo: Identificar los factores de riesgo asociados a hipoglucemia en neonatos a término en un hospital público del norte del Perú mediante la creación de un modelo predictivo utilizando regresión logística. Material y métodos: El estudio presentó un diseño de casos y controles pareado por sexo 1:1, con una muestra de 58 casos y 58 controles, según la presencia o no de hipoglucemia neonatal. Se analizaron variables maternas y neonatales: edad gestacional, peso del recién nacido, sexo del recién nacido, tipo de parto, uso de corticoides, inducción del parto, ser hijo de madre diabética, retraso en el crecimiento intrauterino (RCIU), madre con trastorno hidroelectrolítico previo al parto, síndrome de aspiración meconial y estrés perinatal. Resultados: En el análisis multivariado, se observó que el ser hijo de madre diabética es un factor de riesgo para el desarrollo de hipoglucemia neonatal (OR 4,08, IC95% 1,31-14,18, p=0,02). Conclusión: Existe una asociación significativa entre ser hijo de madre diabética y desarrollar hipoglucemia neonatal.

This research aims to determine the impact of privatization on the financial performance of State-Owned Enterprises (SOEs) in the Indonesia Stock Exchange. This type of research is comparative, data sources using secondary data with data collection techniques using documentation and literature studies.The population in this research is all State-Owned Enterprises (SOEs) that have been privatized in IDX. The sampling method uses purposive sampling with 5 companies. Data analysis techniques using normality testing, independent sample T-test, and Wilcoxon test. The results showed that there was a difference in the financial performance of SOES after privatization was seen from the ratio of solvency, activity, and solvency with significance values of 0.030, 0.170, and 0.001. Whereas if viewed from the liquidity ratio, the privatization does not give the difference in the financial performance of the State-Owned Enterprises (SOEs) in IDX with a significance value of 0.088. This insulation also finds that privatization has a bad impact on the performance of State-Owned Enterprises (SOEs) from profitability and activity ratios, but has a good impact when viewed from the ratio of solvency and liquidity.

Published: December 2020

The article presents results of the analysis of interaction of the factors determining the process of the winter and spring runoff formation on the basis of integrated hydro/meteorological observations at the Lammin-Suo (Leningrad Oblast) and ILass (Archangel Oblast) oligotrophic bogs during the period of stabilization (1950-980) and the period of climate change (1981-2018). We have stated that the freezing depth is a factor that regulates the ratio between the winter runoff and spring runoff. It has been shown that the layer of the winter runoff-forming moisture increase with its decrease and, consequently, the winter runoff is increasing while the spring runoff is decreasing. Analysis of results of the observation over the hydrological regime of the bogs of the north and north-west of Russia has shown that it is exactly the 1978-1980 period that is the boundary, which the freeze depth decrease and the change of the characteristics of runoff from bogs can be observed.
Alternative Approach to the Methodology of Ecological Normalization
Authors:   G.A.  Oboldina
Published: December 2020

The paper considers legal, regulatory/methodical, and scientific foundations of the system of ecological normalization of negative impacts caused by economic activities upon water environment by setting norms of quality and permissible impact.The developed system is represented by a combination of methodological provisions and instruments based on the analysis of the best available techniques in the sphere of monitoring data processing, the use of linear trends of the compressed characteristics, and indirect unified assessment of negative impacts as responses to any kind of economic activities. To provide experts with an objective toolbox and specified provisions we have developed a package of water/protective standards to support assessment of the water quality depletion, water systems degradation, actual and permissible anthropogenic load, and solution of other water/environmental problems. Approval of standardized algorithms of expert actions based on the impact monitoring data gives grounds for possible ecologization of the Water Code in order to assess the aquatic systems safety and to implement the state regulatory function of natural resources protection.

The necessity of early diagnosis of respiratory diseases, especially in the context of the COVID-19 pandemic, by means of pulse oximetric screening and monitoring has been substantiated. The expediency of using portable pulse oximeters by therapists and general practitioners has been shown. The main respiratory diseases accompanied by respiratory failure, which can be detected in time by pulse oximetry, are the chronic obstructive pulmonary disease and the obstructive sleep apnea-hypopnea syndrome. Early detection of these diseases is an important task because of the mild symptoms of these diseases in the early stages, and as a result, the prevalence of late diagnosis. Special attention is given to the pulse oximetry for COVID-19 detection, as this infection is also accompanied by respiratory failure. The use of oxygen concentrators and auto CPAP devices for the treatment of respiratory failure as well as rehabilitation has been argued. The effectiveness of the appointment of long-term oxygen therapy using oxygen concentrators for patients with chronic obstructive pulmonary disease, CPAP therapy using automatic CPAP devices for patients with obstructive sleep apnea-hypopnea syndrome with mandatory pulse oximetry monitoring has been confirmed. The analysis of 120 cases of treatment of moderate and severe COVID-19 cases complicated by the pneumonia has been carried out. The efficiency of the use of oxygen concentrators for supplying oxygen to patients at a flow rate not more than 5 l/min has been proven. It has been found that no more than 10 % of patients needed an oxygen flow rate more than 5 l/min. At the same time, the possibility of using CPAP devices for non-invasive ventilation of lungs using full-face masks has been shown. The expediency of using oxygen concentrators and CPAP devices for the rehabilitation of patients after COVID-19 has been noted.

High-power high-brightness broad-area diode lasers have poor lateral beam quality, which has limited the application range of this kind of device. To improve the lateral beam quality, a sawtooth microstructure laser was proposed and the microstructures were carefully designed according to the profiles of each lateral mode and their dependence on the self-heating induced thermal lens effect. As a result of selective mode loss adjustment, a 42% improvement in lateral beam quality was achieved under the power-maintained condition. This technology enables us to develop high-brightness direct-diode laser systems.
