Malignant Transformation of Oral Lichen Planus—An Umbrella Study of Systematic Reviews
Authors: Warnakulasuriya Saman , Ramos-García Pablo , González-Moles Miguel Ángel
Published: July 2023

Oral lichen planus (OLP) is classified as a potentially malignant disorder. Systematic reviews collating longitudinal observation studies provide evidence of the rate or proportion of malignant transformation. We conducted an umbrella study of published systematic reviews. An extensive English-language study search was carried out in several databases to identify relevant articles, providing systematic reviews on the malignant transformation of OLP. Data from eight systematic reviews published between 2014 and 2023 are presented. The reported proportions of malignant transformation ranged from 1.1% to 1.4%. A meta-analysis based on the 10 highest-quality studies yielded a higher proportion of malignant transformation (2.28%). We list some limitations found in several of these systematic reviews. Some studies reported an increased risk of malignancy in OLP lesions, demonstrating epithelial dysplasia. In view of the consistent evidence of the risk of oral malignancy, OLP patients should be monitored carefully to detect early cancer development.

Published: July 2023

We present a gradient method for designing cascaded diffractive optical elements (DOEs) consisting of several sequentially located phase DOEs. Using the unitarity property of the operator of light propagation through the cascaded DOE, we obtain explicit expressions for the derivatives of the error functional with respect to the phase functions of the cascaded DOE. We consider the application of the gradient method to the problem of focusing different incident beams to regions with different intensity distributions and to the problem of optical image classification. The presented description of the gradient method treats the problems of designing cascaded DOEs for focusing laser radiation and for image classification within a unified approach reducing the calculation of the derivatives of the error functionals to the same formula. We present examples of the calculation of single and cascaded DOEs for focusing different incident beams to different regions and for classifying handwritten digits, which demonstrate the high performance of the proposed method. The presented results may find application in the design of diffractive neural networks and systems for focusing laser radiation.

Published: July 2023

A self-homodyne coherent (SHC) transmission system that has a good prospect in terms of short-reach interconnections can simplify digital signal processing (DSP) and reduce the power consumption of laser diodes. However, the polarization control of the carrier becomes a pivotal part of these systems, and different from the traditional polarization control on a certain state of polarization (SOP), it only needs to lock the two polarization lights after the polarization beam splitter (PBS) in a state of equal power. Half-wave plates or Mach–Zehnder interferometers can accomplish the above goals. In order to evaluate the performance of these polarization control structures in the SHC system, we modeled them on the basis of theoretical analysis. Furthermore, a variable-step greedy linear descent (GLD) algorithm is proposed to solve the power fluctuation problem caused by the accelerated change of SOP near the pole of the Poincaré sphere. The simulation results indicate that the variable-step GLD algorithm can effectively improve the tracking ability of the polarization control loop up to approximately 1.5 times of the GLD algorithm and the gradient descent (GD) algorithm.

Authors: Kim Heetae , Jeon Sungmin , Jung Yoochul , Kim Juwan
Published: July 2023

In this paper, the magnetic heating effect of the superconducting quarter-wave resonator (QWR) cavities is investigated, and the Q slopes of the superconducting cavities are measured with an increasing accelerating field. Bardeen–Cooper–Schrieffer (BCS) resistance is calculated for the zero-temperature limit. The vertical test is shown for the performance test of the QWR cavities. The parameters for the QWR cavity are presented. The Q slopes are measured as a function of an accelerating electric field at 4.2 K. The surface resistance of the superconducting cavity increases with an increasing peak magnetic field. The magnetic defects degrade the quality factor. From the magnetic degradation, we determine the magnetic moments of the superconducting cavities. All quarter-wave resonator (QWR) cryomodules are installed in the tunnel, and beam commissioning is performed successfully.

Authors: Cai Yi , Li Bijun , Zhou Jian , Zhang Hongjuan , Cao Yongxing
Published: July 2023

Removing moving objects from 3D LiDAR data plays a crucial role in advancing real-time odometry, life-long SLAM, and motion planning for robust autonomous navigation. In this paper, we present a novel method aimed at addressing the challenges faced by existing approaches when dealing with scenarios involving significant registration errors. The proposed approach offers a unique solution for removing moving objects without the need for registration, leveraging range flow estimation combined with IMU measurements. To this end, our method performs global range flow estimation by utilizing geometric constraints based on the spatio-temporal gradient information derived from the range image, and we introduce IMU measurements to further enhance the accuracy of range flow estimation. Through extensive quantitative evaluations, our approach showcases an improved performance, with an average mIoU of 45.8%, surpassing baseline methods such as Removert (43.2%) and Peopleremover (32.2%). Specifically, it exhibits a substantial improvement in scenarios characterized by a deterioration in registration performance. Moreover, our method does not rely on costly annotations, which make it suitable for SLAM systems with different sensor setups.

Published: July 2023

Upper extremity hemiplegia is a serious problem affecting the lives of many people post-stroke. Motor recovery requires high repetitions and quality of task-specific practice. Sufficient practice cannot be completed during therapy sessions, requiring patients to perform additional task practices at home on their own. Adherence to and quality of these home task practices are often limited, which is likely a factor reducing rehabilitation effectiveness post-stroke. However, home adherence is typically measured by self-reports that are known to be inconsistent with objective measurement. The objective of this study was to develop algorithms to enable the objective identification of task type and quality. Twenty neurotypical participants wore an IMU sensor on the wrist and performed four representative tasks in prescribed fashions that mimicked correct, compensatory, and incomplete movement qualities typically seen in stroke survivors. LSTM classifiers were trained to identify the task being performed and its movement quality. Our models achieved an accuracy of 90.8% for task identification and 84.9%, 81.1%, 58.4%, and 73.2% for movement quality classification for the four tasks for unseen participants. The results warrant further investigation to determine the classification performance for stroke survivors and if quantity and quality feedback from objective monitoring facilitates effective task practice at home, thereby improving motor recovery.
A New Spatial Registration Algorithm of Aerial Moving Platform to Sea Target Tracking
Authors: Dai Qiuyang , Lu Faxing
Published: July 2023

Spatial registration is the primary challenge affecting target tracking accuracy, especially for the aerial moving platform and sea target tracking. In this environment, it is important to account for both the errors in sensor observations and the variations in platform attitude. In order to solve the problem of complex types of errors in the tracking of sea targets by aerial moving platforms, a new spatial registration algorithm is proposed. Through separating and analyzing observation data, the influence of sensor observation error and attitude error on observation data is obtained, and a systematic error consistency matrix is established. Based on observation information from multiple platforms, accurate tracking of sea targets can be accomplished without estimating systematic error. In order to verify the effectiveness of the algorithm, we carried out simulation experiments and practical experiments on the lake, which showed that the new algorithm was more efficient than traditional algorithms.

Published: July 2023

This paper presents a personalized and smart flowerpot for ornamental horticulture, integrating 3D printing and cloud technology to address existing design limitations and enable real-time monitoring of environmental parameters in plant cultivation. While 3D printing and cloud technology have seen widespread adoption across industries, their combined application in agriculture, particularly in ornamental horticulture, remains relatively unexplored. To bridge this gap, we developed a flowerpot that maximizes space utilization, simplicity, personalization, and aesthetic appeal. The shell was fabricated using fused deposition modeling (FDM) in 3D printing, and an Arduino-based control framework with sensors was implemented to monitor critical growth factors such as soil moisture, temperature, humidity, and light intensity. Real-time data are transmitted to the Bamfa Cloud through Wi-Fi, and a mobile application provides users with instant access to data and control over watering and lighting adjustments. Our results demonstrate the effectiveness of the smart flowerpot in enabling automated monitoring of plant growth and environmental control. This innovation holds significant promise for advancing smart device development in ornamental horticulture and other related fields, enhancing efficiency, plant health, and overall user experience. Future research in this area has the potential to revolutionize horticultural practices and contribute to the advancement of smart agriculture.

Published: July 2023

Autonomous vehicles (AVs) rely on advanced sensory systems, such as Light Detection and Ranging (LiDAR), to function seamlessly in intricate and dynamic environments. LiDAR produces highly accurate 3D point clouds, which are vital for the detection, classification, and tracking of multiple targets. A systematic review and classification of various clustering and Multi-Target Tracking (MTT) techniques are necessary due to the inherent challenges posed by LiDAR data, such as density, noise, and varying sampling rates. As part of this study, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was employed to examine the challenges and advancements in MTT techniques and clustering for LiDAR point clouds within the context of autonomous driving. Searches were conducted in major databases such as IEEE Xplore, ScienceDirect, SpringerLink, ACM Digital Library, and Google Scholar, utilizing customized search strategies. We identified and critically reviewed 76 relevant studies based on rigorous screening and evaluation processes, assessing their methodological quality, data handling adequacy, and reporting compliance. As a result of this comprehensive review and classification, we were able to provide a detailed overview of current challenges, research gaps, and advancements in clustering and MTT techniques for LiDAR point clouds, thus contributing to the field of autonomous driving. Researchers and practitioners working in the field of autonomous driving will benefit from this study, which was characterized by transparency and reproducibility on a systematic basis.
Wavelet-Based Output-Only Damage Detection of Composite Structures
Authors: Janeliukstis Rims , Mironovs Deniss
Published: July 2023

Health monitoring of structures operating in ambient environments is performed through operational modal analysis, where the identified modal parameters, such as resonant frequencies, damping ratios and operation deflection shapes, characterize the state of structural integrity. The current study shows that, first, time-frequency methods, such as continuous wavelet transform, can be used to identify these parameters and may even provide a large amount of such data, increasing the reliability of structural health monitoring systems. Second, the identified resonant frequencies and damping ratios are used as features in a damage-detection scheme, utilizing the kernel density estimate (KDE) of an underlying probability distribution of features. The Euclidean distance between the centroids of the KDEs, at reference and in various other cases of structural integrity, is used as an indicator of deviation from reference. Validation of the algorithm was carried out in a vast experimental campaign on glass fibre-reinforced polymer samples with a cylindrical shell structure subjected to varying degrees of damage. The proposed damage indicator, when compared with the well-known Mahalanobis distance metric, yielded comparable damage detection accuracy, while at the same time being not only simpler to calculate but also able to capture the severity of damage.

Published: July 2023

This paper evaluates the potential application of Raman baselines in characterizing organic deposition. Taking the layered sediments (Stromatolite) formed by the growth of early life on the Earth as the research object, Raman spectroscopy is an essential means to detect deep-space extraterrestrial life. Fluorescence is the main factor that interferes with Raman spectroscopy detection, which will cause the enhancement of the Raman baseline and annihilate Raman information. The paper aims to evaluate fluorescence contained in the Raman baseline and characterize organic sedimentary structure using the Raman baseline. This study achieves spectral image fusion combined with mapping technology to obtain high spatial and spectral resolution fusion images. To clarify that the fluorescence of organic matter deposition is the main factor causing Raman baseline enhancement, 5041 Raman spectra were obtained in the scanning area of 710 μm × 710 μm, and the correlation mechanism between the gray level of the light-dark layer of the detection point and the Raman baseline was compared. The spatial distribution of carbonate minerals and organic precipitations was detected by combining mapping technology. In addition, based on the BI-IHS algorithm, the spectral image fusion of Raman fluorescence mapping and reflection micrograph, polarization micrograph, and orthogonal polarization micrograph are realized, respectively. A fusion image with high spectral resolution and high spatial resolution is obtained. The results show that the Raman baseline can be used as helpful information to characterize stromatolite organic sedimentary structure.

Published: July 2023

Amitriptyline residue released into the aquatic ecosystem can have detrimental consequences on marine organisms and human wellbeing via consumption of polluted water. With a uniquely large surface area and abundant functionalities, graphene oxide adsorption offers a remediation solution for such water pollution. This study focused on synthesizing a novel graphene-based adsorbent via ice-templating of boron-doped graphene substrate. The batch adsorption performance of the as-synthesized adsorbent was explored by central composite design (CCD), while its potential large-scale application was evaluated with a packed-bed column study. The CCD optimized conditions of 12.5 mg dosage, 32 min adsorption time, 30 °C operating temperature and 70 ppm concentration produced the highest removal efficiency of 87.72%. The results of the packed-bed study indicated that continuous adsorption of amitriptyline was best performed at a graphene bed of 3.5 cm in height, with 100 ppm of the pharmaceutical solution flowing at 2 mL/min. Furthermore, the breakthrough curve was effectively portrayed by the Log Bohart–Adams model. The as-synthesized adsorbent showed a high regeneration potential using ethanol eluent via multiple adsorption–desorption cycles. The results suggest the boron-doped graphene adsorbent in packed-bed as a highly effective system to remediate amitriptyline in an aqueous environment.

Published: July 2023

Parental involvement of super-diverse families in the educational process is an integral part of the integration of emergent bilingual students, which, however, entails obstacles to its implementation in Greek schools and worldwide. Τhe present study investigates, through a qualitative case study, the perceptions of eight primary school teachers who had worked in zones of educational priority (ZEPs) in Greek public education, which are also called reception classes, towards the involvement of immigrant and refugee parents in the educational process as well as the barriers that influence it. The methodological tool of semi-structured interviews was used, while the sample was selected with both the convenience and snowball sampling techniques. Some important results reveal the usefulness of parental involvement for all involved persons in the school–family partnership as well as the multiple obstacles to its implementation. The main difficulties encountered by the participants were the parents’ lack of competence in Greek or in an intermediate language as well as their unfamiliarity with a culturally different education system. In response to this reality, the establishment of translation services at school with language and cultural interpreters that could bridge theses distances while recognizing families’ differences as an asset rather as an obstacle emerges as a necessity.

Published: July 2023

In China, the majority of mountainous regions are characterized by complex topography and a delicate, sensitive geological environment. These areas, which exhibit insufficient infrastructure and widespread irrational human engineering activities, are often susceptible to geological hazards such as slope instability and soil mass movements. These geological hazards pose substantial threats to human lives and property, hindering the progress of mountainous areas. Therefore, conducting research on evaluating the vulnerability of slope rock and soil mass movement geological hazards (hereinafter referred to as geological hazards) is of utmost importance for hazard prevention, emergency management, and economic advancement in these regions. This study focuses on Xuanwei City and selects eight factors for evaluation, including elevation, gradient, slope aspect, normalized vegetation index, stratigraphic lithology, distance from faults, distance from rivers, and distance from roads. These factors are chosen based on a comprehensive analysis of the spatial and temporal distribution of geological hazards and hazard incubation conditions. Two paired models, the deterministic coefficient model + logistic regression model (CF+LR) and the information quantity model + logistic regression model (I+LR), were employed to assess the study area quantitatively. The performance of these models was assessed by employing receiver operating characteristic (ROC) curves and calculating the corresponding area under curve (AUC) values. The results indicate that: (1) The AUC values for the coupled CF+LR and I+LR models are 0.799 and 0.772, respectively. These results indicate that both models provide an objective and reliable assessment of the vulnerability to geological hazards, specifically slope rock and soil mass movements, in the study area. (2) Based on the CF+LR model calculations, the geological hazard susceptibility of Xuanwei City can be categorized into four zones: extremely high susceptibility (6.09%), high susceptibility (31.08%), medium susceptibility (32.26%), and low susceptibility (30.57%). (3) The CF+LR model more accurately represents the evaluation results and offers a strong reference value.

Authors: Bie Hongling , Li Pengyu , Chen Fenghua , Ghaderpour Ebrahim
Published: July 2023

Non-holonomic wheeled robots (NWR) comprise a type of robotic system; they use wheels for movement and offer several advantages over other types. They are efficient, highly, and maneuverable, making them ideal for factory automation, logistics, transportation, and healthcare. The control of this type of robot is complicated, due to the complexity of modeling, asymmetrical non-holonomic constraints, and unknown perturbations in various applications. Therefore, in this study, a novel type-3 (T3) fuzzy logic system (FLS)-based controller is developed for NWRs. T3-FLSs are employed for modeling, and the modeling errors are considered in stability analysis based on the symmetric Lyapunov function. An observer is designed to detect the error, and its effect is eliminated by a developed terminal sliding mode controller (SMC). The designed technique is used to control a case-study NWR, and the results demonstrate the good accuracy of the developed scheme under non-holonomic constraints, unknown dynamics, and nonlinear disturbances.

Published: July 2023

Weaning entails numerous modifications of the intestinal structure and microbiota composition, making puppies at high risk of sickness during this delicate life stage. The aim of this study was to investigate the effects of a four-week administration of a supplement composed of ultramicronised Palmitoylethanolamide, bovine colostrum and Bacillus subtilis (Normalia® Extra, Innovet Italia Srl, Saccolongo, Italy) on markers of gut health and microbiome of weaning puppies. Twenty-nine four-week-old Golden Retriever puppies were randomly assigned to control (CG, n = 13) and treated (TG, n = 16) groups. During the whole experimental time, there were no differences between the groups with regard to average daily gain and faecal score. In TG, faecal calprotectin and zonulin values were statistically significantly decreased compared to CG, especially at week 8 (zonulin: 42.8 ± 1.54 ng/mL and 55.3 ± 42.8 ng/mL, and calprotectin: 2.91 ± 0.38 µg/g and 5.71 ± 0.43 µg/g, in TG and CG, respectively; p < 0.0001 for both comparisons). Bacteria belonging to phylum Campylobacterota decreased (p = 0.04), while those referring to genera Coprococcus and Pseudomonas increased (p = 0.01 and p = 0.04, respectively). The supplementation of the tested complementary feed can promote the intestinal health of puppies and therefore facilitate weaning by lowering gut inflammation.

Published: July 2023

The condition of asphalt concrete and its standard service life on public roads are the main indicators of the road surface. The factors of violation of the top layer of asphalt concrete from increased dynamic effects of the wheel load of vehicles are considered. Performance indicators are characterized by strength and deformation characteristics. The factors providing the necessary deformation and strength parameters during the operation of the roadway are analyzed and justified. The indicators and conditions of contact of the surface of the crushed granulate in the zone of contact with the binding components are determined. A method of using asphalt granulate of three standard sizes in the formation of the top layer of pavement with a normative, operational service life and rational use of material and technical resources at all stages of the formation and laying of asphalt concrete is proposed. The strength of the dispersed system is achieved during the formation of an asphalt mixture by increasing the density, strength, adhesion of the binder, water resistance and preservation of the structure of the pavement. The experiment established the volumetric and fractional standard size of asphalt granulate in the total volume of the mixture. The volume composition of the granulate content in the total volume of the mixture is from 20% to 25%.

Published: July 2023

A model of plasticity of reinforced concrete structures is considered, based on on the transformations of the intensity of the “stress-strain” connection by projecting the tensors of this connection, using special transitions for the main angle of deformations, total shear deformations, etc.). At the same time, the modulus of plasticity of concrete, the coefficient of transverse deformations are determined, and complex functions are constructed for linear and angular deformations in sections, taking into account deformation, gradients of deformations during the formation of cracks and stiffness changes. The hypotheses adopted for the calculation model determine the distribution of force flows - blocks for compressed and stretched concrete (first object), "main cracks" from the mechanics of destruction of reinforced concrete, complex functions and a two-cantilever element for modeling the deformation effect of reinforced concrete, developed by the author (second object). Tensile concrete resistance is transferred to the working reinforcement and is modeled using the sum of the average values of the longitudinal and transverse forces, as well as the average reduced coefficient of tension concrete. The "pin (nagel)" effect in the reinforcement crossed by a crack was obtained using the model of the second level of structural mechanics for a reinforcing bar with two pinched ends. The opening of the crack and the shift of the crack edges are simulated. The main force vector in the reinforcement is characterized by the values of longitudinal and transverse displacements (the third object).

Published: July 2023

Background

Lifestyle intervention programmes target behavioural risk factors that contribute to cardiovascular diseases (CVDs). Unfortunately, sustainable implementation of these programmes can be challenging. Gaining insights into the barriers and facilitators for successful implementation is important for maximising public health impact of these interventions. The Healthy Heart (HH) programme is an example of a combined lifestyle intervention programme.

Aim

To analyse the reach, adoption, and implementation of the HH programme.

Design & setting

A mixed-methods study conducted in a general practice setting in The Netherlands.

Method

Quantitative data were collected from the Healthy Heart study (HH study), a non-randomised cluster stepped-wedge trial to assess the effect of the HH programme on patients at high risk of developing CVDs at practice level. Qualitative data were obtained through focus groups.

Results

Out of 73 approached general practices, 55 implemented the HH programme. A total of 1082 patients agreed to participate in the HH study, of whom 64 patients were referred to the HH programme and 41 patients participated. Several barriers for participation were identified such as time investment, lack of risk perception, and being confident in changing lifestyle on their own. Important barriers for healthcare providers (HCPs) to refer a patient were time investment, lack of information to sufficiently inform patients, and preconceived notions regarding which patients the programme was suitable for.

Conclusion

This study has offered insights from a patient and HCP perspective regarding barriers and facilitators for implementation of the group-based lifestyle intervention programme. The identified barriers and facilitators, and the suggested improvements, can be used by others who wish to implement a similar programme.

La educación sexual de carácter integral en la enseñanza de la Geografía en América Latina
Authors: Moreno Magdalena
Published: July 2023

En los últimos años, con la masificación de los reclamos de los colectivos de mujeres cisgénero y del colectivo LGBTTIQ+, se ha reavivado el debate sobre la importancia de la implementación de la educación sexual. Las instituciones educativas se constituyen como lugares de socialización atravesados por la agenda social y representan el ámbito en donde resuenan dichos debates. Así, surge la demanda de propuestas pedagógicas que dialoguen con los debates del contexto social contemporáneo. En este artículo se reflexiona acerca de los vínculos que se han establecido entre la enseñanza de la Geografía y la Educación Sexual, especialmente, la de carácter Integral. Para esto, se realiza un abordaje general del tema a modo de presentación introductoria. En un comienzo, para contextualizar la situación latinoamericana, se presenta el estado de situación de las diferentes legislaciones que habilitan la incorporación explícita de la educación sexual a las currículas escolares. Luego, el análisis se centra en los principales aportes y posicionamientos políticos de la Ley de Educación Sexual Integral de Argentina, pionera en el continente. A continuación, se realiza una aproximación a los estudios de América Latina acerca de la enseñanza de la Geografía en diálogo con la educación sexual. Esto se realiza a través de la recuperación bibliográfica de los trabajos científicos publicados, a modo de estado de la cuestión. Por último, se plantean los desafíos actuales que presenta el diálogo entre la enseñanza de la Geografía y la Educación Sexual Integral.

Published: July 2023

En el ciclo lectivo 2021, como equipo de cátedra del seminario “Contra-cartografías del neoliberalismo. Luchas y movimientos sociales en defensa de los territorios y la vida”, del Departamento de Geografía de la Facultad de Filosofía y Humanidades (FFyH) de la Universidad Nacional de Córdoba (UNC), llevamos a cabo en co-coordinación con la organización social Todes con DNI, un taller denominado “Contra-cartografías del neoliberalismo e identidades de género como una contra-cartografía en acción”, cuyo fin fue el generar instancias de trabajo colaborativo en donde se abordara el eje de identidades de género y de territorio-cuerpo, poniendo el foco en las particularidades de las diversas corporalidades y cada territorio para elaborar estrategias de intervención que puedan ser llevadas a cabo en distintos espacios. En el presente trabajo, partimos de recuperar dicha experiencia como un ejercicio que posibilita desmontar convenciones de lo cisheteropatriarcal, para abrir un espacio de reflexión crítica en torno a las identidades de género como contracartografías y, a su vez, las contracartografías como herramienta de disputa ante el sistema cisheteropatriarcal-colonial-capitalista. El foco está puesto tanto en lo político-pedagógico como en las narrativas y experiencias que surgieron en relación a las espacialidades de las identidades de género trans y travesti.
Geógrafas en resistencia. Casos de Uruguay, Chile, Argentina y México (1970-1980)
Authors: Ibarra García María Verónica
Published: July 2023

Este trabajo se enmarca en la geografía feminista y tiene como objetivo presentar a geógrafas latinoamericanas que desarrollaron su formación y/o producción durante las dictaduras militares y el autoritarismo en México. Estas geógrafas no solo generaron conocimiento, sino que también formaron profesionales de la geografía e impulsaron líneas de investigación, contribuyendo al desarrollo de una nueva geografía en América Latina. Se inicia con estas geógrafas por haber vivido la represión debido a sus posiciones políticas y/o académicas. Algunas no pudieron dar clases en universidades, otras tuvieron que exiliarse y algunas resistieron en sus países de origen. La investigación se basó en fuentes primarias y secundarias. Entre las limitaciones se encuentra el hecho de que existen pocos estudios centrados en su papel en el desarrollo de la geografía, con excepción de Elena Chiozza y Graciela Uribe. Cabe destacar que este trabajo no incluye a las geógrafas brasileñas, ya que esto rebasaría el objetivo de este primer acercamiento, aunque es imprescindible integrarlas para tener una mirada latinoamericana completa. La contribución busca dar visibilidad a las geógrafas que, a pesar de las condiciones políticas adversas que vivieron en los años 70 y 80, contribuyeron a la conformación de una geografía crítica desde Latinoamérica.

A jornada de trabalho dos caminhoneiros brasileiros está, como regra, ligada à sua relação trabalhista com a transportadora contratante. O principal objetivo da pesquisa foi identificar e analisar os principais aspectos de saúde e segurança ocupacional que afetam os motoristas autônomos. A pesquisa consistiu em uma revisão da literatura nas bases de dados SciELO, Scopus e Web of Science, na qual se utilizou um processo estruturado, abrangendo um planejamento, execução e análise dos dados pesquisados. A fadiga e a sonolência durante a atividade são consideradas um grande problema de saúde para a categoria, não só porque afetam o bem-estar, mas também porque impactam no desempenho da condução do veículo e, consequentemente, na segurança. Os achados vão ao encontro das discussões trazidas sobre a crescente informalização do trabalho dos autônomos, que os submete à contratos temporários, sem garantias de direitos trabalhistas, com jornadas exaustivas. Este artigo faz uma reflexão sobre a fadiga e a sonolência como as principais causas dos acidentes de trânsito, tornando-se imprescindível o estabelecimento de condições mínimas a serem observadas por qualquer contratante do serviço.

Os estudos acerca da caminhabilidade propõem avaliar a qualidade do deslocamento dos pedestres e os fatores que influenciam as decisões pela viagem a pé. Nas últimas três décadas autores se dedicam a responder a estas questões, afinal, o caminhar é o mais elementar modo de deslocamento, e está presente em todo território brasileiro. O objetivo desse trabalho é propor uma metodologia para elaboração de um Índice de Caminhabilidade para a cidade de Montes Claros/MG. Como objetivos específicos, propõe a apreensão de estudos voltados para os deslocamentos pedonais e a utilização do método de análise multicritério AHP – Analytic Hierarchy Process para desenvolver o Índice de Caminhabilidade. A metodologia foi construída em duas etapas. A primeira efetua uma revisão nos aspectos teóricos da caminhabilidade. A segunda consiste na construção do Índice de Caminhabilidade realizada em três atividades: i) análise de multicritério para definição dos pesos dos indicadores de caminhabilidade, resultante da opinião de especialistas e da percepção de pedestres; ii) definição de critérios para avaliação dos indicadores; e iii) aplicação do modelo matemático para o cálculo do índice de caminhabilidade. Os resultados refletem a relevância dos indicadores: existência de calçada, iluminação, e manutenção/conservação de calçada, e mostram o quão é fundamental entender as especificidades locais na avaliação da caminhabilidade.

High-performance photodetectors hold promising potential in optical communication and imaging systems. However, conventional counterparts are suffering narrow detection range, high power consumption, and poor polarization sensitivity. Characteristics originating from switchable polarization in ferroelectrics can be used to optimize the photo-to-electric procedure and improve the photodetection performance. In this regard, we constructed a configuration by integrating 2-dimensional molybdenum disulfide (MoS
2
) with ferroelectric lithium niobate (LiNbO
3
), resulting in the MoS

/LiNbO

heterostructured photodetector. Benefiting from the pyroelectric effect of LiNbO

, the limitation of bandgap on the detection range can be broken, thus broadening the response band of the detector to 365 to 1,064 nm, as well as enabling the self-powered characteristic. Meanwhile, high carrier mobility and decent light absorbance of MoS

introduce robust light-matter interactions with the underlying LiNbO

, leading to ultrafast rise/fall times of ≈150 μs/250 μs and switching ratios of up to ≈190. Moreover, the highest responsivity, specific detectivity, and external quantum efficiency achieved were 17.3 A·W

Jones, and 4,645.78%, respectively. Furthermore, because of the anisotropy of the spontaneous-polarized LiNbO

substrate, the photocurrent of the device achieved a dichroic ratio of 7.42, comparing favorably to most MoS

-based photodetectors. This work demonstrates the integration potential between ferroelectric LiNbO

and 2-dimensional materials for high-performance photodetection.
Tracing the Impact of the Digital Virtual Ludic on Immersive Theatre: A Case of Theatre Gamification
Authors: Charitos Dimitrios , Timplalexi Eleni
Published: July 2023

Immersive theatre, a theatrical form emerging at the beginning of the 21st century, invites spectators to become immersed in interactive theatre performances. The use of the term immersive indicates a strong influence from digital media, particularly from virtual worlds (VWs). Immersive theatre and VWs appear to share characteristics. A systematic comparative approach tracing the presence of characteristics shared by immersive theatre and VWs (i.e., virtuality, worldliness, information intensity), among others, still unique to VWs (i.e., agency, ergodicity), reveals that immersive theatre has assimilated some VWs characteristics while still being in the process of negotiating others. The paradigm of pervasive games is brought into the conversation to claim immersive theatre as a partially successful case of theatre gamification, revising theatrical and dramatic conventions, towards what could be called a digitally and ludically inspired neo-dramatic. New intermedial forms of expression could benefit from the adoption of a game/play frame.
Viability of Using Digital Games for Improving Team Cohesion: A Systematic Review of the Literature
Authors: Kovalčík Juraj , Švecová Magdaléna , Kabát Michal
Published: July 2023

Team cohesion, teamwork and team building are important constructs regarding teams and their performance in various organizations and environments. In this review, we sum- marize the current state of research on the influence of digital games on team cohesion and related constructs. We found a total of 7 studies that fit the criteria, resulting in 18 outcomes. Among the 18 outcomes that improved throughout the intervention, 15 reported significant improvement from the intervention and 3 reported no significant differences. Specifically, team communication, task delegation, atmosphere, trust, team flow, team performance and goal commitment were the most improved sub-constructs by team building video gaming interventions. The majority (n = 9) of those with significant improvements post-test were from randomly controlled trials (RCTs) with single or two control groups. Overall, we found that team video gaming may be effective in supporting team cohesion or team building; however, to enhance the understanding of the relationship between digital games and team cooperation, it is recommended to extend or vary gameplay intervention times, prioritize diverse outcome measures, address re- porting biases, conduct follow-up assessments, include diverse populations and report demographics, and recognize the specific effects of different game features on outcomes.

Authors: Kvetanová Zuzana
Published: July 2023

The presented study closely explains R. Caillois’ theory of game principles, while attempt- ing to point out its apparent application in the digital dimension. It is our main intention to clarify the significance and topicality of the characteristics of individual game categories within media products – digital games. Thus, confrontation between the fundamental theoretical framework and its consequent practical application within the selected case study occurs in the submitted scientific text. The study’s ambition is to identify the indicative characteristics of R. Caillois’ game categories in the selected media product – the digital game Sudden Strike 4. The chosen research material can be qualified as a suitable representative of the strategy game genre, which was the direct determinant of our selection. Therefore, the primary objective of the study is to ascertain the possible application of R. Caillois’ game theory in the strategy game genre. For the purposes of achieving the defined objective, the author uses methods of logical analysis of text in combination with qualitative content (narrative) analysis. She thus presumes a certain increase and revaluation of the existing scientific knowledge necessary for both the theory and practice.

Thalassemia is a hematological disorder caused by a gene mutation that leads to defective synthesis of hemoglobin complex. One of the complications of thalassemia is hypocalcemia which is presented with paresthesia, muscle spasm, low-serum calcium, and intracranial calcification. Hypocalcemia can affect thalassemic patients via various mechanisms. Blood transfusion-related and transfusion-independent iron overload, drug side effects, vitamin D3 deficiency, and genetic disorders and polymorphisms are among the etiologies of hypocalcemia in major thalassemia. A careful approach to the differential etiology of this phenomenon is crucial for a resultful treatment.
