Influence of the Cross-Sectional Shape and Corner Radius on the Compressive Behaviour of Concrete Columns Confined by FRP and Stirrups
Authors: Wei Yang , Xu Yang , Wang Gaofei , Cheng Xunyu , Li Guofen
Published: January 2022

Axial compression tests were carried out on 72 FRP (fiber reinforced polymer)–stirrup composite-confined concrete columns. Stirrups ensure the residual bearing capacity and ductility after the FRP fractures. To reduce the effect of stress concentration at the corners of the confined square-section concrete columns and improve the restraint effect, an FRP–stirrup composite-confined concrete structure with rounded corners is proposed. Different corner radii of the stirrup and outer FRP were designed, and the corner radius of the stirrup was adjusted accurately to meet the designed corner radius of the outer FRP. The cross-section of the specimens gradually changed from square to circular as the corner radius increased. The influence of the cross-sectional shape and corner radius on the compressive behaviour of FRP–stirrup composite-confined concrete was analysed. An increase in the corner radius can cause the strain distribution of the FRP to be more uniform and strengthen the restraint effect. The larger the corner radius of the specimen, the better the improvement of mechanical properties. The strength of the circular section specimen was greatly improved. In addition, the test parameters also included the FRP layers, FRP types and stirrup spacing. With the same corner radius, increasing the number of FRP layers or densifying the stirrup spacing effectively improved the mechanical properties of the specimens. Finally, a database of FRP–stirrup composite-confined concrete column test results with different corner radii was established. The general calculation models were proposed, respectively, for the peak points, ultimate points and stress–strain models that are applicable to FRP-, stirrup- and FRP–stirrup-confined concrete columns with different cross-sectional shapes under axial compression.

Authors: Martwong Ekkachai , Chuetor Santi , Junthip Jatupol
Published: January 2022

Cationic organic pollutants (dyes and pesticides) are mainly hydrosoluble and easily contaminate water and create a serious problem for biotic and abiotic species. The elimination of these dangerous contaminants from water was accomplished by adsorption using cyclodextrin nanosponges. These nanosponges were elaborated by the cross-linking between 1,2,3,4-butanetetracarboxylic acid and β-cyclodextrin in the presence of poly(vinyl alcohol). Their physicochemical characteristics were characterized by gravimetry, acid-base titration, TGA, 13C NMR, ATR-FTIR, Raman, X-ray diffraction, and Stereomicroscopy. The BP5 nanosponges displayed 68.4% yield, 3.31 mmol/g COOH groups, 0.16 mmol/g β-CD content, 54.2% swelling, 97.0% PQ removal, 96.7% SO removal, and 98.3% MG removal for 25 mg/L of initial concentration. The pseudo-second-order model was suitable for kinetics using 180 min of contact time. Langmuir isotherm was suitable for isotherm with the maximum adsorption of 120.5, 92.6, and 64.9 mg/g for paraquat (PQ), safranin (SO), and malachite green (MG) adsorption, respectively. Finally, the reusability performance after five regeneration times reached 94.1%, 91.6%, and 94.6% for PQ, SO, and MG adsorption, respectively.

Published: January 2022

Prayer is one of the most important aspects of religious/spiritual life. The psychological literature has identified various types of prayer and a few methods for measuring it. The Multidimensional Prayer Inventory (MPI) has received much attention from researchers since it allows for the capture of the most universal forms of prayer, characteristic of the Judeo-Christian tradition: Adoration, Confession, Thanksgiving, Supplication, and Reception. The aim of this article was to examine psychometric properties and clinical applications of the Polish MPI. In four studies, we established the internal structure of the MPI using Principal Component Analysis (PCA, study 1) and Confirmatory Factor Analysis (CFA, study 2), examined its validity and reliability in relation to religiousness (study 3), and analysed its clinical application (study 4). The Polish MPI has been confirmed as a reliable and valid measure of five types of prayer for use in research settings.
GNSS Aided Long-Range 3D Displacement Sensing for High-Rise Structures with Two Non-Overlapping Cameras

Published: January 2022

Image-based displacement measurement techniques are widely used for sensing the deformation of structures, and plays an increasing role in structural health monitoring owing to its benefit of non-contacting. In this study, a non-overlapping dual camera measurement model with the aid of global navigation satellite system (GNSS) is proposed to sense the three-dimensional (3D) displacements of high-rise structures. Each component of the dual camera system can measure a pair of displacement components of a target point in a 3D space, and its pose relative to the target can be obtained by combining a built-in inclinometer and a GNSS system. To eliminate the coupling of lateral and vertical displacements caused by the perspective projection, a homography-based transformation is introduced to correct the inclined image planes. In contrast to the stereo vision-based displacement measurement techniques, the proposed method does not require the overlapping of the field of views and the calibration of the vision geometry. Both simulation and experiment demonstrate the feasibility and correctness of the proposed method, heralding that it has a potential capacity in the field of remote health monitoring for high-rise buildings.
Automatic Extraction of Damaged Houses by Earthquake Based on Improved YOLOv5: A Case Study in Yangbi
Authors: Jing Yafei , Ren Yuhuan , Liu Yalan , Wang Dacheng , Yu Linjun
Published: January 2022

Efficiently and automatically acquiring information on earthquake damage through remote sensing has posed great challenges because the classical methods of detecting houses damaged by destructive earthquakes are often both time consuming and low in accuracy. A series of deep-learning-based techniques have been developed and recent studies have demonstrated their high intelligence for automatic target extraction for natural and remote sensing images. For the detection of small artificial targets, current studies show that You Only Look Once (YOLO) has a good performance in aerial and Unmanned Aerial Vehicle (UAV) images. However, less work has been conducted on the extraction of damaged houses. In this study, we propose a YOLOv5s-ViT-BiFPN-based neural network for the detection of rural houses. Specifically, to enhance the feature information of damaged houses from the global information of the feature map, we introduce the Vision Transformer into the feature extraction network. Furthermore, regarding the scale differences for damaged houses in UAV images due to the changes in flying height, we apply the Bi-Directional Feature Pyramid Network (BiFPN) for multi-scale feature fusion to aggregate features with different resolutions and test the model. We took the 2021 Yangbi earthquake with a surface wave magnitude (Ms) of 6.4 in Yunan, China, as an example; the results show that the proposed model presents a better performance, with the average precision (AP) being increased by 9.31% and 1.23% compared to YOLOv3 and YOLOv5s, respectively, and a detection speed of 80 FPS, which is 2.96 times faster than YOLOv3. In addition, the transferability test for five other areas showed that the average accuracy was 91.23% and the total processing time was 4 min, while 100 min were needed for professional visual interpreters. The experimental results demonstrate that the YOLOv5s-ViT-BiFPN model can automatically detect damaged rural houses due to destructive earthquakes in UAV images with a good performance in terms of accuracy and timeliness, as well as being robust and transferable.
Wavelength-Dependent Seeing Systematically Changes the Normalized Slope of Telescopic Reflectance Spectra of Mercury
Authors: Wohlfarth Kay , Wöhler Christian
Published: January 2022

Telescopic observations of Mercury consistently report systematic variations of the normalized spectral slope of visible-to-near-infrared reflectance spectra. This effect was previously assumed to be a photometric property of the regolith, but it is not yet fully understood. After the MESSENGER mission, detailed global spectral maps of Mercury are available that better constrain Mercury’s photometry. So far, wavelength-dependent seeing has not been considered in the context of telescopic observations of Mercury. This study investigates the effect of wavelength-dependent seeing on systematic variations of Mercury’s normalized spectral reflectance slope. Therefore, we simulate the disk of Mercury for an idealized scenario, as seen by four different telescopic campaigns using the Hapke and the Kaasalainen–Shkuratov photometric model, the MDIS global mosaic, and a simple wavelength-dependent seeing model. The simulation results are compared with the observations of previous telescopic studies. We find that wavelength-dependent seeing affects the normalized spectral slope in several ways. The normalized slopes are enhanced near the limb, decrease toward the rim of the seeing disk, and even become negative. The decrease of the normalized spectral slope is consistent with previous observations. However, previous studies have associated the spectral slope variations with photometric effects that correlate with the emission angle. Our study suggests that wavelength-dependent seeing may cause these systematic variations. The combined reflectance and seeing model can also account for slope variations between different measurement campaigns. We report no qualitative differences between results based on the Hapke model or the Kaasalainen–Shkuratov model.
Understanding Electric Bicycle Users’ Mode Choice Preference under Uncertainty: A Case Study of Shanghai
Authors: Xin Feifei , Chen Yifan , Ye Yitong
Published: January 2022

The electric bicycle is considered as an environmentally friendly mode, the market share of which is growing fast worldwide. Even in metropolitan areas which have a well-developed public transportation system, the usage of electric bicycles continues to grow. Compared with bicycles, the power transferred from the battery enables users to ride faster and have long-distance trips. However, research on electric bicycle travel behavior is inadequate. This paper proposes a cumulative prospect theory (CPT) framework to describe electric bicycle users’ mode choice behavior. Different from the long-standing use of utility theory, CPT considers travelers’ inconsistent risk attitudes. Six socioeconomic characteristics are chosen to discriminate conservative and adventurous electric bicycle users. Then, a CPT model is established which includes two parts: travel time and travel cost. We calculate the comprehensive cumulative prospect value (CPV) for four transportation modes (electric bicycle, bus, subway and private car) to predict electric bicycle users’ mode choice preference under different travel distance ranges. The model is further validated via survey data.

Published: January 2022

Multilevel inverters (MLIs) are capable of producing high-quality output voltage and handling large amounts of power. This reduces the size of the filter while also simplifying the circuitry. As a result, they have a wide range of applications in industries, particularly in smart grids. The input voltage boosting feature is required to use the MLI with renewable energy. Moreover, many components are required to get higher output voltage levels that add weight and cost to the circuit. Numerous MLI topologies have been identified to minimize the losses, device count, and device ratings. A seven-level modified H-bridge inverter with a reduced component count, and reduced THD is presented in this paper. Two DC sources with six IGBTs have been used to generate a seven-level output voltage, and the Aquila Optimizer (AO) has been implemented to get the regulated output. MATLAB/Simulink environment has been used for designing the simulation model. Furthermore, the simulation result has been validated in the laboratory on a hardware setup using the DSP-TMS320F28335 Launchpad. With the reduced number of switching devices as well as the dc supply, the size of the inverter is compacted and becomes more economical.

Published: January 2022

Health service providers in developed nations are responsible for 5% of their national carbon emissions, much of which originate from transport and supply chains. Connected autonomous freight vehicles (CAV-Fs) offer the potential to reduce this impact and enable lower cost operations, with trials being explored across the world. Transportation and carriage regulations, particularly in relation to the movement of dangerous goods (DG) such as medicines and diagnostic specimens, have not been developed for and applied to this new transport mode, particularly where loads are unaccompanied. Through an audit of current legislation and practice, this paper evaluates current DGs regulations applied to the transportation of medical products and medicines by autonomous road vehicles. Where existing regulations are not appropriate for CAV-Fs, recommendations and adaptations have been proposed to support safe and practical application. Remote monitoring and tracking of vehicles are critical for ensuring load security, quick and effective incident response, and management of documents and communications between parties. Loading/unloading procedures are significantly more important than in crewed vehicles, with load segregation and recording of all activity being of key importance. Other recommendations relate to training provision, vehicle specifications, and product health monitoring.
Outdoor Thermal Environments of Main Types of Urban Areas during Summer: A Field Study in Wuhan, China
Authors: Li Kun , Li Xuefei , Yao Keji
Published: January 2022

Under the influence of the urban heat island effect, the thermal environments of urban built-up areas are poor, leading to the loss of urban vitality and the extreme deterioration of thermal comfort. In this paper, the outdoor thermal environment in Wuhan’s main urban area is studied via the use of field measurements. From June to August in the years 2015 to 2017, 20 measurement points were selected for monitoring from 08:00 to 19:00 h, which were located in spaces such as residential areas, parklands, commercial streets, and college/university campuses. The measurements for the same types of land and different types of land use are analyzed. A comprehensive thermal environment index is used to quantitatively evaluate the overall situations of thermal environments. The results showed that the cooling effect of vegetation shading was stronger than the effect of water evaporation and the maximum temperature difference between the two cooling methods reached 6.1 °C. The cooling effect of the canopy shading of tall trees was stronger than the effect of grassland transpiration and the maximum temperature difference was 2.8 °C. The streets with higher aspect ratios might improve the ventilation, but the wind speeds remained low, which did not provide a strong cooling effect. This study helps urban planners understand the thermal environment of Wuhan or similar cities with hot summer and diversified urban areas, and puts forward suggestions to reduce the heat island effect from the aspect of building layout, green coverage, shading mode, and street aspect ratio, so as to establish sustainable cities that are climate adaptable and environmentally friendly.

Published: January 2022

It is becoming increasingly clear that linear modes of production and consumption are unsustainable. A circular economy would help to minimize both environmental and social problems. As a result, the concept is gaining momentum in the political discourse. However, current policies do not seem sufficient to transform linear value chains to circular ones. This paper compares the potentials of and prerequisites for a circular economy along two important value chains. As a best practice example, the legal framework along the battery value chain is analyzed. This analysis is used to derive recommendations for how to improve the legal framework along the building value chain. We find that the battery value chain is already addressed by targeted instruments and the instruments addressing the building value chain have to be aligned and their credibility improved through mandatory requirements. A value chain-specific approach to develop the legal framework is promising for key sectors, while both general frameworks and value chain-specific instruments are required to fully exploit the CE for every product.
Experimental Study on the Interplay between Different Brine Types/Concentrations and CO2 Injectivity for Effective CO2 Storage in Deep Saline Aquifers

Published: January 2022

Salt precipitation during CO2 storage in deep saline aquifers can have severe consequences on injectivity during carbon storage. Extensive studies have been carried out on CO2 solubility with individual or mixed salt solutions; however, to the best of the authors’ knowledge, there is no substantial study to consider pressure decay rate as a function of CO2 solubility in brine, and the range of brine concentration for effective CO2 storage. This study presents an experimental core flooding of the Bentheimer sandstone sample under simulated reservoir conditions to examine the effect of four different types of brine at a various ranges of salt concentration (5 to 25 wt.%) on CO2 storage. Results indicate that porosity and permeability reduction, as well as salt precipitation, is higher in divalent brines. It is also found that, at 10 to 20 wt.% brine concentrations in both monovalent and divalent brines, a substantial volume of CO2 is sequestered, which indicates the optimum concentration ranges for storage purposes. Hence, the magnitude of CO2 injectivity impairment depends on both the concentration and type of salt species. The findings from this study are directly relevant to CO2 sequestration in deep saline aquifers as well as screening criteria for carbon storage with enhanced gas and oil recovery processes.

Published: January 2022

We consider the Cauchy problem of the three-dimensional primitive equations of geophysics. By using the Littlewood–Paley decomposition theory and Fourier localization technique, we prove the global well-posedness for the Cauchy problem with the Prandtl number P=1 in variable exponent Fourier–Besov spaces for small initial data in these spaces. In addition, we prove the Gevrey class regularity of the solution. For the primitive equations of geophysics, our results can be considered as a symmetry in variable exponent Fourier–Besov spaces.
Enhanced Air Stability of Perovskite Quantum Dots by Manganese Passivation
Authors: Sato Ryota , Umemoto Kazuki , Asakura Satoshi , Masuhara Akito
Published: January 2022

Organic-inorganic perovskite quantum dots (PeQDs) have attracted attention due to their excellent optical properties, e.g., high photoluminescence quantum yields (PLQYs; >70%), a narrow full width at half maximum (FWHM; 25 nm or less), and color tunability adjusted by the halide components in an entire tunability (from 450 nm to 730 nm). On the other hand, PeQD stability against air, humidity, and thermal conditions has still not been enough, which disturbs their application. To overcome these issues, with just a focus on the air stability, Mn2+ ion passivated perovskite quantum dots (Mn/MAPbBr3 QDs) were prepared. Mn2+ could be expected to contract the passivating layer against the air condition because the Mn2+ ion was changed to the oxidized Mn on PeQDs under the air conditions. In this research, Mn/MAPbBr3 QDs were successfully prepared by ligand-assisted reprecipitation (LARP) methods. Surprisingly, Mn/MAPbBr3 QD films showed more than double PLQY stability over 4 months compared with pure MAPbBr3 ones against the air, which suggested that oxidized Mn worked as a passivating layer. Improving the PeQD stability is significantly critical for their application.

Published: January 2022

An increasing number of studies have begun considering human endogenous retroviruses (HERVs) as potential pathogenic phenomena. Our previous research suggests that HERV-W Envelope (HERV-W ENV), a HERV-W family envelope protein, is elevated in schizophrenia patients and contributes to the pathophysiology of schizophrenia. The dopamine (DA) hypothesis is the cornerstone in research and clinical practice related to schizophrenia. Here, we found that the concentration of DA and the expression of DA receptor D2 (DRD2) were significantly higher in schizophrenia patients than in healthy individuals. Intriguingly, there was a positive correlation between HERV-W ENV and DA concentration. Depth analyses showed that there was a marked consistency between HERV-W ENV and DRD2 in schizophrenia. Studies in vitro indicated that HERV-W ENV could increase the DA concentration by regulating DA metabolism and induce the expression of DRD2. Co-IP assays and laser confocal scanning microscopy indicated cellular colocalization and a direct interaction between DRD2 and HERV-W ENV. Additionally, HERV-W ENV caused structural and functional abnormalities of DA neurons. Further studies showed that HERV-W ENV could trigger the PP2A/AKT1/GSK3 pathway via DRD2. A whole-cell patch-clamp analysis suggested that HERV-W ENV enhanced sodium influx through DRD2. In conclusion, we uncovered a relationship between HERV-W ENV and the dopaminergic system in the DA neurons. Considering that GNbAC1, a selective monoclonal antibody to the MSRV-specific epitope, has been promised as a therapy for treating type 1 diabetes and multiple sclerosis (MS) in clinical trials, understanding the precise function of HERV-W ENV in the dopaminergic system may provide new insights into the treatment of schizophrenia.
IFN-γ Attenuates Eosinophilic Inflammation but Is Not Essential for Protection against RSV-Enhanced Asthmatic Comorbidity in Adult Mice
Authors: Muralidharan Abenaya , Uddin Md Bashir , Bauer Christopher , Wu Wenzhe , Bao Xiaoyong , Sun Keer
Published: January 2022

The susceptibility to respiratory syncytial virus (RSV) infection in early life has been associated with a deficient T-helper cell type 1 (Th1) response. Conversely, healthy adults generally do not exhibit severe illness from RSV infection. In the current study, we investigated whether Th1 cytokine IFN-γ is essential for protection against RSV and RSV-associated comorbidities in adult mice. We found that, distinct from influenza virus, prior RSV infection does not induce significant IFN-γ production and susceptibility to secondary Streptococcus pneumoniae infection in adult wild-type (WT) mice. In ovalbumin (OVA)-induced asthmatic mice, RSV super-infection increases airway neutrophil recruitment and inflammatory lung damage but has no significant effect on OVA-induced eosinophilia. Compared with WT controls, RSV infection of asthmatic Ifng−/− mice results in increased airway eosinophil accumulation. However, a comparable increase in eosinophilia was detected in house dust mite (HDM)-induced asthmatic Ifng−/− mice in the absence of RSV infection. Furthermore, neither WT nor Ifng−/− mice exhibit apparent eosinophil infiltration during RSV infection alone. Together, these findings indicate that, despite its critical role in limiting eosinophilic inflammation during asthma, IFN-γ is not essential for protection against RSV-induced exacerbation of asthmatic inflammation in adult mice.

SARS-CoV-2 variants of concern (VOCs) or of interest (VOIs) causing vaccine breakthrough infections pose an increased risk to worldwide public health. An observational case-control study was performed of SARS-CoV-2 vaccine breakthrough infections in hospitalized or ambulatory patients in Monterrey, Mexico, from April through August 2021. Vaccination breakthrough was defined as a SARS-CoV-2 infection that occurred any time after 7 days of inoculation with partial (e.g., first dose of two-dose vaccines) or complete immunization (e.g., second dose of two-dose vaccines or single-dose vaccine, accordingly). Case group patients (n = 53) had partial or complete vaccination schemes with CanSino (45%), Sinovac (19%), Pfizer/BioNTech (15%), and AstraZeneca/Oxford (15%). CanSino was administered most frequently in ambulatory patients (p < 0.01). The control group (n = 19) received no COVID-19 vaccines. Among SARS-CoV-2 variants detected by whole-genome sequencing, VOC Delta B.1.617.2 predominated in vaccinated ambulatory patients (p < 0.01) and AY.4 in hospitalized patients (p = 0.04); VOI Mu B.1.621 was detected in four (7.55%) vaccinated patients. SARS-CoV-2 breakthrough infections in our hospital occurred mostly in patients vaccinated with CanSino due to the higher prevalence of CanSino vaccine administration in our population. These patients developed mild COVID-19 symptoms not requiring hospitalization. The significance of this study lies on the detection of SARS-CoV-2 variants compromising the efficacy of local immunization therapies in Monterrey, Mexico.

This cross-sectional study, conducted in Naples (Italy) between 16 November and 6 December 2021, explored the willingness to receive the booster dose of the COVID-19 vaccine among a random sample selected from the list of those who had completed a primary vaccination series at the immunization center of a teaching hospital in Naples and the associated factors. Females had a significantly higher perceived risk of getting the SARS-CoV-2 infection, whereas those not-having a cohabitant were less worried. 85.7% were willing to receive the booster dose. Those older respondents who perceived a better health status after the primary vaccination series, who have friends/family members who were diagnosed with COVID-19, who had received information from official government organizations, and those who did not need information would be willing to get the booster dose. 24.7% was hesitant with a Vaccine Hesitancy Scale (VHS) score ≥ 25. Respondents who self-rated a lower health status after the primary vaccination series, who did not have friends/family members who were diagnosed with COVID-19, who had not received information from official government organizations, and who needed information were hesitant. Information and communication regarding the benefits and efficacy of the booster dose are needed in order to control the pandemic.

River water quality degradation is one of the hottest environmental issues worldwide. Therefore, monitoring water quality longitudinally and temporally is crucial for effective water management and contamination control. The main aim of this study was to assess the longitudinal variations in water quality in the mainstream of the Han River, Korea, from 2015 to 2019. The trophic state classification (TSC), microbial pollution indicator (MPI), and river pollution index (RPI) were calculated to characterize river water quality and revealed more serious pollution toward the downstream zone (Dz) due to agricultural and urban-dominated areas. The biodegradability index (BI) indicated that non-biodegradable organic pollutants are increasing in the water body from the urban and animal wastewater treatment plants. Nutrients, organic matter contents, total suspended solids, ionic factors, and algal chlorophyll were higher in the Dz than in any other zones and were markedly influenced by the summer monsoon. Empirical analysis showed that nutrients and organic matter had positive linear functional relations with agricultural and urban coverage and negative linear relations with forest coverage. The pollutant-transport function suggested that suspended solids act as TP and TN carriers. Regression analysis indicated that TP (R2 = 0.47) has more positive functional relations with algal growth than TN (R2 = 0.22). Our findings suggest that a combination of empirical models and pollution indices might be utilized to assess river water quality and that the resulting information could aid policymakers in managing the Han River.

Published: January 2022

The Netherlands is a state located in Western Europe bordering Germany and Belgium. The population of the country is just over 17million people. In terms of GDP, theNetherlands is among the twenty richest countries in the world, and in terms of exports, it is in the top ten. The average life expectancy in theNetherlands is 81.4 years; in the structure ofmortality, malignant neoplasms come out on top, which distinguishes the state from other European countries, where the main cause of deaths is cardiovascular diseases. The compulsory health insurance system was introduced in the country in 2006 after the medical reform. A distinctive feature of the Dutch healthcare system is its relative autonomy from the state, which performs only the function of an external controller, and all other powers belong to the municipal authorities. As a result, several private insurance companies have been admitted to health insurance in the Netherlands, which create healthy competition among themselves, thereby contributing to better quality and more affordable healthcare.

Published: January 2022

Após profundas transformações ocorridas no início da pós-modernidade, inovações tecnológicas e, em consequência, o aperfeiçoamento das redes surgiram como estratégias de fomento a circulação e aos fluxos. Dessa maneira, os diferentes territórios estão cada vez mais articulados e pautados na fluidez, constituindo redes urbanas cada vez mais densas e abrangentes. Este artigo investiga como a circulação inserida no âmbito da estruturação da rede urbana e sua consoante hierarquia urbana promovem a dispersão do número de casos de COVID-19 na microrregião de Presidente Prudente. Para tanto, uma revisão bibliográfica inicial foi realizada; a análise da dispersão do número de casos apoiou-se em dados retirados do Fundação Sistema Estadual de Análise de Dados – SEADE, resultando em produções cartográficas que representam a quantidade de casos acumulados, em números absolutos e relativos, pelos municípios em cinco diferentes momentos: 01/05/2020, 01/08/2020, 01/11/2020, 01/02/2021 e 01/06/2021. A investigação permitiu inferir que a dispersão do número de casos se deu, sobretudo, em função da circulação promovida pelo papel da centralidade exercida pelos municípios mais importantes da hierarquia urbana da microrregião, segundo a Regiões de Influência das Cidades – REGIC.

Introducción. La persona adulta mayor ve afectadas sus funciones, auditivas, visuales y de movilidad; enfrenta limitaciones para incorporarse a los grupos sociales y la autodeterminación, que en ocasiones le posicionan en condición de dependencia para cubrir sus necesidades básicas afectando su calidad de vida. La comunicación es fundamental para el desarrollo de sus funciones, en el caso del distanciamiento social por COVID-19, la afectó la relación interpersonal y el intercambio de información. La comunicación evita la disminución de las funciones cognitivas y el deterioro paulatino que propicia la exclusión social. S1 Investigación de revisión evaluativa, documental, centrada en la comunicación, calidad de vida, adulto mayor. La revisión de la literatura publicada de 2019-2020, en el contexto de la pandemia por Covid-19, con base en los descriptores de “Calidad de vida”, “Adulto mayor”, “Comunicación”, “aislamiento social”, “COVID 19”, “soledad”. La estructura metodológica y conceptual, se basó en el análisis: 7 trabajos: 1 revisión sistemática, 3 estudios descriptivos, 2 ensayos y 1 tesis de grado. Resultados. Con base en los núcleos temáticos, se contrastaron planteamientos teóricos sustentados en el fomento de la comunicación y la diversificación a través de las TICs, calidad de vida, en el distanciamiento social por COVID-19, que constituye un riesgo para la salud y bienestar en el adulto mayor. Discusión. Los recursos tecnológicos para la comunicación son esenciales en la pandemia por COVID-19. Sin embargo, existe la brecha generacional, la carencia de recursos económicos para adquirirlos, entre otros factores que obstaculizan establecer una comunicación satisfactoria.

Este documento nace como la experiencia de siete años de aplicar la prueba “Mi sistema de comunicación” en el curso de reclutamiento y selección de personal de la carrera de administración y gestión de recursos humanos (AGRH) de la Universidad Técnica Nacional (UTN). Esta prueba se utiliza en procesos de selección de personas en las diferentes organizaciones del país y por el Programa de Habilidades Blandas Empresariales (PROHABLA) de la Universidad Nacional de Costa Rica. El objetivo es conocer el estilo de comunicación de los estudiantes de AGRH para el establecimiento de estrategias organizacionales que se ajusten a sus necesidades. Metodología: Las investigadoras deciden aplicar esta prueba a cuatro grupos de estudiantes utilizando la herramienta Google form, y se utiliza la triangulación en el análisis de los datos. Resultados: La mayoría de las personas participantes son kinésicas y/o kinestésicas, sobresalen los sentidos del tacto, gusto y olfato. Discusión: Los resultados se considera buenos pues la metodología de la Universidad está basada en el “saber-hacer” por tanto al aplicar los sentidos del tacto, gusto y olfato el estudiantado fortalece la comunicación basada en a través de actividades que se basan en las experiencias vivenciales (ejecutar y vivir cada situación). Conclusiones: Una vez que se conocen los resultados se dan dos situaciones a saber: 1) El profesorado puede diseñar las actividades de clase con las estrategias que favorecen la comunicación. 2) El estudiantado reconoce las fortalezas en sus sentidos y aprovechan estos recursos para potenciar otros sentidos y comunicarse de forma integral.

Saat melakukan praktik laut, peneliti menemukan adanya masalah saat kapal akan melakukan proses pendinginan muatan di kapal LPG, bahwa sebelum memulai kegiatan bongkar muatan harus terlebih dahulu melaksanakan Pendinginan Matuatan. Pendinginan muatan sendiri merupakan proses yang di lakukan untuk menjaga kuantitas muatan yang di bawa agar sesuai dengan bill of lading dengan yang tertera. Namun yang terjadi di atas kapal proses pendinginan muatan tidak di lakukan sesuai prosedur. Hal ini mengakibatkan keterlambatan pada proses bongkar muat. Kemudian ketika proses pendinginan, prosedur pendinginan tidak sesuai dengan apa yang di tetapkan. Sehingga proses bonkar muatan terlambat. Hal ini dapat mengakibatkan kerugian kepada berbagai pihak. Skripsi ini dibuat untuk mencegah ketidaksesuaian tempratur muatan dengan ketentuan yang diberikan pihak charterer. Peneliti menggunakan metode penelitian kualitatif dengan metode pengumpulan data observasi dan wawancara. Untuk mencegah terjadinya ketidaksesuaian temperatur muatan dengan ketentuan yang diberikan, kapal harus selalu melakukan pengoperasian yang tepat dan sesuai dengan prosedur yang benar sehingga kerusakan dan permasalahan dapat di cegah sebelum terjadi.

Indonesia adalah salah satu negara yang merupakan pelaku impor dan juga ekspor. Berdasarkan jalur yang digunakan, terdapat tiga jalur untuk melakukan impor dan ekspor yaitu jalut darat, udara dan laut. Jalur laut adalah yang banyak diminati oleh sebagian besar pelaku impor dan ekspor. PT Evergreen adalah perusahaan pelayaran yang mana bertanggungjawab atas kondisi dan penanganan peti kemas dari pelabuhan asal ke pelabuhan tujuan. Pengaruh penanganan dan biaya perbaikan kontainer impor di PT Evergreen Shipping Agency Indonesia disebabkan oleh masalah kecepatan pengangkutan yang menyebabkan peningkatan biaya pengangkutan kontainer ekspor dan impor selalu meningkat dari tahun ke tahun. Selain itu, situasi ekspor dan impor Indonesia yang masih sangat terfragmentasi juga menjadi faktor yang melatar belakangi meningkatnya penanganan dan biaya perbaikan kontainer import. Adapun kendala umum pada penanganan kontainer yaitu faktor cuaca dan kesalahan manusia (human error). Penelitian ini ditujukan untuk mengetahui seberapa besar pengaruh proses penanganan kontainer import terhadap biaya perbaikan kontainer di PT Evergreen Shipping Agency Indonesia.
The directionality of interjoint neural coupling in the impaired upper extremity post stroke

 To date, research has primarily focused on identifying and analyzing abnormal coupling in the upper extremity following stroke during gross movements such as reaching. Yet, little is known about the direction of abnormal coupling in conjunction with its degree between joints—muscles—of interest. In this study, we address the directionality of pathological neural couplings between joints, and variability in the degree of them, in the upper extremity post stroke. To evaluate the direction of interjoint coupling, joint motion and muscle activity in an involuntary mode while another joint—muscle—was voluntarily activated were assessed in comparison to those made in a volitional mode, focusing on the shoulder, elbow and wrist joints. Overall, involuntary activation of the wrist flexor in the stroke group is observed when muscles of a more proximal joint voluntarily activate (p < 0.1 and p <0.05), while activation of the wrist flexor does not lead to involuntary activation of the shoulder muscles and elbow flexor, in comparison to the healthy group. In particular, in the stroke group who is assumed to have a severe loss of the corticospinal system, the wrist extensor is subordinately activated by those about the other joints voluntarily activated (p < 0.05) while it does not cause activations of those about the other joints. These findings indicate that stroke-caused synergies could be directional, implying the existence of a cortical source and/or neural pathway for a muscle that is not paired with that for other muscles.
