Factores determinantes el fracaso escolar en España: un análisis socioeducativo de la producción de conocimiento
Authors: Moles-López Elisabet , Añaños Fanny T- , Burgos Jiménez Rubén J.
Published: June 2023

Objetivo: La presente investigación analiza los factores que determinan el fracaso escolar en España, utilizando la “Encuesta Social 2010: Educación y Hogares en Andalucía”[1], mediante una muestra de 5032 casos, de gran representatividad. Originalidad/aporte: El fracaso escolar es un tema de sumo interés socioeducativo en las investigaciones actuales, así como un objetivo prioritario de actuación para la Unión Europea debido a las altas tasas registradas en los últimos años. Método: Parte de un análisis sistematizado documental desde un enfoque cuantitativo. Estrategias/recolección de información: Se realiza una explotación de datos secundarios de la encuesta, haciendo inferencia con la situación actual mediante dos modelos de regresión logística binaria para las cohortes de edad. Los resultados muestran una brecha de sexo en la probabilidad de fracaso escolar, ya que las mujeres obtienen menor riesgo. El nivel sociofamiliar indica que la importancia que otorgan los padres/madres/tutores a la educación no es un factor que influye en el fracaso escolar; sin embargo, el control parental hacia los estudios de educación secundaria disminuye su probabilidad. El nivel socioeconómico familiar representa un factor prioritario que interviene en la probabilidad de que se produzca. Conclusiones: Los hallazgos realzan la necesidad de adecuación y actualización de los datos sobre los factores que determinan el fracaso escolar desde una perspectiva socioeducativa y de género, de modo que permitan una intervención socioeducativa y la aplicación de políticas educativas-sociales coherentes con la realidad social, atendiendo a las características y condiciones específicas del alumnado, a fin de ejercer acciones de prevención, fomentar el desarrollo integral e integración social.

Authors: Stanciu Nicolae V.
Published: June 2023

Recent initiatives to promote digital education exhorting in literacy and soft skills as computational thinking have required redefining curricula, teaching and learning methods adapted to a new channel of communication. Less attention has been paid to the psychological dimensions of learning and teaching Romanian as a second language, especially to language awareness and motivation of learners in the field. Beginning with what is generally known as communication schemata and ethnography of communication this article analyzes the strategies used in a narrow strip of learning and teaching Romanian as a foreign language in North Macedonia through online classes and workshops of lexicography and translations.

Published: June 2023

The COVID-19 pandemic process has been associated with particularly strong declines in the academic, social, and psychological conditions of university students. Concerns about COVID-19 have often been correlated with worsening well-being. Besides the burdens most university students face, student-athletes have also been exposed to these psycho-social consequences. Therefore, it is important to examine the protective factors against psychological adjustment skills. Concepts such as resilience and endurance, which are defined as one's ability to react to difficulties, can also be protective factors. With the ongoing pandemic process, resilience and endurance in university students who are athletes and non-athletes have not yet been examined in this context. For this reason, this study aims to examine the mediator role of resilience in the relationship between mental well-being, COVID-19 anxiety, and burnout. 778 university students, 412 athletes and 366 non-athletes, studying in different departments of the university participated in the study. As data collection tools, COVID-19 related anxiety scale, short psychological resilience scale, Warwick-Edinburgh mental well-being scale short form and maslach burnout scale student form were used. The relationships between the anxiety, burnout, mental well-being and psychological resilience levels of the athletes and non-athletes were determined by the Pearson product moment correlation coefficient. Structural equation modeling was used in data analysis to determine the direct and indirect predictive effects between variables. During the research process, all analyzes were made using SPSS 22.00 and AMOS package programs. The results showed that resilience was negatively related to COVID-19 anxiety and burnout, and positively related to mental well-being in both groups. Resilience mediated significant effects on COVID-19 anxiety, burnout, and mental well-being for students in both groups.

Transkrypcja aktów urodzenia dzieci par jednopłciowych. Rozważania „de lege lata” i „de lege ferenda fundamentali”
Authors: Tracz Katarzyna
Published: June 2023

Celem rozważań jest przedstawienie kwestii dopuszczalności transkrypcji aktów urodzenia dzieci par jednopłciowych. Polski porządek prawny nie akceptuje małżeństw homoseksualnych, co prowadzi do odmowy dokonania transkrypcji takich aktów ze względu na zastosowanie klauzuli porządku publicznego. W konsekwencji małoletni obywatel Rzeczypospolitej Polskiej pozbawiony jest możliwości uzyskania dokumentów tożsamości oraz nadania numeru PESEL, co utrudnia wykonywanie przysługujących mu praw obywatelskich oraz wynikających z prawa unijnego — prawa do swobodnego przemieszczania się i pobytu na terenie państw członkowskich. W pracy szczegółowej analizie poddane zostało orzecznictwo sądów administracyjnych oraz Trybunału Sprawiedliwości Unii Europejskiej w odniesieniu do rozwiązań prawnych de lege lata oraz jego wpływ na praktykę organów administracji publicznej. Ocenie poddano także projekt ustawy nowelizującej regulacje dotyczące transkrypcji pod kątem postulowanych rozwiązań de lege ferenda.
Prying open the space for social work in the new millennium
Authors: Houston Stan , Skehill Caroline , Pinkerton John , Campbell Jim
Published: June 2023

Social work in the United Kingdom faces all manner of woes. Critical public inquiries, disgruntled users of the service, the bureaucratisation of practice, problems with recruitment, and the overhaul of training, all continue to reinforce a culture of pessimism. It has been suggested that social work in the United Kingdom stands at the crossroads where a decision must be made either to accept these depressing conditions as they are, or to challenge them by asserting a new future for a reinvigorated profession. The latter option is supported by the authors of this article because we share the view that as social workers we have available to us discursive freedom with which to analyse the profession’s contemporary ailments and to find a way through them based on a discourse of social justice. The idea and practice of discursive freedom can be captured in the heuristic notion of ‘space’ which the authors use here as a shared focus for analysing contemporary social work from four different critical perspectives. In this way a dialogue is promoted between theory and practice and within critical theory. In its method and its results this inquiry is still very much work-in-progress. This provisional quality sits comfortably with the notion of ‘space’ and gives rein to its recursive qualities. These qualities, it is argued, must lie at the heart of transformative social work.
Thoraco-laparotomy approach to salvage a life-threatening cardiac box stab injury to the infecrior vena cava in Malaysia: a case report

Published: June 2023

Torso stab injuries near the cardiac box may present unique challenges due to difficulties in hemorrhage control. For a stab injury to the heart, the repair is straightforwardly performed via median sternotomy. In contrast, injuries to the inferior vena cava are challenging to repair, especially when they are close to the diaphragm, and the bleeding can be torrential. Herein, we describe a case of a self-inflicted stab wound within the "cardiac box." The trajectory of the stab injuries went below the diaphragm and injured the infradiaphragmatic inferior vena cava. Successful emergent repair via the thoraco-laparotomy approach revived the young man. In this report, we revisit and discuss previous large series of patients with this rare vena cava injury.
Three-column reconstruction through the posterior approach alone for the treatment of a severe lumbar burst fracture: a case report
Authors: Kim Woo Seok , Jeong Tae Seok , Kim Woo Kyung
Published: June 2023

Generally, patients with severe burst fractures, instability, or neurological deficits require surgical treatment. In most cases, circumferential reconstruction is performed. Surgical methods for three-column reconstruction include anterior, lateral, and posterior approaches. In cases involving an anterior or lateral approach, collaboration with general or thoracic surgeons may be necessary because the adjacent anatomical structures are unfamiliar to spinal surgeons. Risks include vascular or lumbar plexus injuries and cage displacement, and in most cases, additional posterior fusion surgery is required. However, the posterior approach is the most common and anatomically familiar approach for surgeons performing spinal surgery. We present a case in which three-column reconstruction was performed using only the posterior approach to treat a patient with a severe lumbar burst fracture.
Importance of ROS1 fene fusions in non-small cell lung cancer

Published: June 2023

Targeted therapy has become one of the standards of care for advanced lung cancer. More than 10 genetic aberrations have been discovered that are actionable and several tyrosine kinase inhibitors (TKIs) have been approved to target each of them. Among several genetic aberrations that are actionable in non-small cell lung cancer (NSCLC), ROS1 translocations also known as gene fusion proteins, are found in only 1%-2% of the patient population. ROS1 mutations can usually be detected using a combination of techniques such as immunohistochemistry (IHC), Fluorescence in-situ testing (FISH), polymerase chain reaction (PCR), and next-generation sequencing (NGS). However, RNA NGS and ctDNA NGS (liquid biopsies) also contribute to the diagnosis. There are currently numerous FDA-approved agents for these tumors, including crizotinib and entrectinib; however, there is in-vitro sensitivity data and clinical data documenting responses to ceritinib and lorlatinib. Clinical responses and survival rates with these agents are frequently among the best compared to other TKIs with genetic aberrations; however, intrinsic or extrinsic mechanisms of resistance may develop, necessitating research for alternative treatment modalities. To combat the mechanisms of resistance, novel agents such as repotrectenib, cabozantinib, talotrectinib, and others are being developed. In this article, we examine the literature pertaining to patients with ROS1 tumors, including epidemiology, clinical outcomes, resistance mechanisms, and treatment options.

This work presents the morphology and characterization of chitosan nanoparticles crosslinked with lecithin in the form of nano-onions obtained by an easy, economical, and possibly scalable method from a polymeric precursor known as chitosan. The creation of new products by using shrimp waste is a fundamental factor in avoiding water pollution. These materials have a positive impact as they add value to waste, and they provide the opportunity to decrease pollution. Chitosan nano-onions were synthesized by an environmentally friendly, easy, and inexpensive method using chitosan as a natural source. Chitosan nano-onions (CSNO) were characterized by using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS) and specific surface area (SSA). The nano-onions characterization obtained by FTIR shows the presence of carbonyl groups at a wavenumber of 1752.12 cm–1, while the phosphate groups attributed to lecithin are observed at 1156.88 cm–1. XRD analysis confirmed an amorphous structure, while SEM images presented a globular morphology with concave surfaces. TEM analysis showed that the nano-onions are congregated in a unique structure that includes nanotubes. The CSNO average diameter by DLS was 442.5 nm with an octagonal arrangement, and a polydispersity index (PDI) of 0.532 and 31.9 mV. The average size of CSNO, the PDI, and the value of zeta potential were indicators of a stable dispersion with a specific superficial area measured by the Brunauer-Emmett-Teller (BET) method of 1.4 m2 g–1. The results of the chitosan-lecithin nano-onions characterization indicate changes in the surface of the material with a larger total surface area and pore structure, compared to that of pure chitosan. According to the results of the CHNO characterization, they could be used as adsorbents for contaminants and they also have a potential application in the biomedical area, mainly as drug encapsulation material.

Published: June 2023

Front-of-pack labelling (FOPL) systems, such as the Nutri-Score, play a crucial role in promoting healthy diets and raising consumer awareness. Our study aimed to gather the opinions of Polish experts on the Nutri-Score and its relation to an ideal information system. We conducted a Poland-wide expert opinion study using a cross-sectional design survey with 75 participants, who had an average of 18±13 years of experience and were mainly employed at medical and agricultural universities. The data were collected with CAWI method. The results showed that the most important features of an FOPL system were clarity, simplicity, consistency with healthy eating recommendations, and the ability to objectively compare products within the same group. While more than half of the respondents believed that the Nutri-Score provides an overall assessment of a product’s nutritional value and facilitates quick purchasing decisions, it falls short in helping consumers compose a balanced diet and cannot be applied to all product groups. The experts also expressed concerns about the system’s ability to account for a product’s degree of processing, full nutritional value and carbon footprint. In conclusion, Poland’s current labelling system needs expansion, but the Nutri-Score requires significant and deep changes and validation against national guidelines and expert expectations before implementation.
SL-Swin: A Transformer-Based Deep Learning Approach for Macro- and Micro-Expression Spotting on Small-Size Expression Datasets
Authors: He Erheng , Chen Qianru , Zhong Qinghua
Published: June 2023

In recent years, the analysis of macro- and micro-expression has drawn the attention of researchers since they provide visual cues of an individual's emotions for a broad range of potential applications such as lie detection and criminal detection. In this paper, we address the challenge of spotting facial macro- and micro-expression from videos and present compelling results by using a deep learning approach to analyze the optical flow features. Different from other deep learning approaches that are mainly based on Convolutional Neural Networks (CNNs), we propose a Transformer-based deep learning approach that predicts a score indicating the probability of a frame being within an expression interval. In contrast to other Transformer-based models that achieve high performance by being pre-trained on large datasets, our deep learning model, called SL-Swin, which incorporates Shifted Patch Tokenization and Locality Self-Attention into the backbone network Swin Transformer, effectively spots macro- and micro-expressions by being trained from scratch on small-size expression datasets. Our evaluation outcomes surpass the MEGC 2022 spotting baseline result, obtaining an overall F1-score of 0.1366. Additionally, our approach also performs well in the MEGC 2021 spotting task with an overall F1-score of 0.1824 and 0.1357 on CAS(ME)^2 and SAMM Long Videos, respectively. The code is publicly available on GitHub (https://github.com/eddiehe99/pytorch-expression-spotting).

Abstract: Background and Objectives: Holter-based late potentials (LPs) are useful for predicting lethal arrhythmias in organic cardiac diseases. Although Holter-based LPs exhibit diurnal varia-tion, no studies have evaluated the optimal timing of LP measurement over 24 h for predicting lethal arrhythmia that leads to sudden cardiac death. Thus, this study aimed to validate the most effective timing for Holter-based LP testing and to explore factors influencing diurnal variability of LP parameters. Materials and Methods: We retrospectively analyzed 126 patients with post-myocardial infarction (MI) status and 60 control participants who underwent high-resolution Holter electrocardiography. Among the 126 post-MI patients, 23 developed sustained ventricular tachycardia (VT) (the MI-VT group), while 103 did not (the MI-non-VT group) during the obser-vation period. Holter-based LPs were measured at 0:00, 4:00, 8:00, 12:00, 16:00, and 20:00, and heart rate variability analysis was simultaneously performed to investigate factors influencing diurnal variability of LP parameters. Results: Holter-based LP parameters showed diurnal variation with significant deterioration at night and improvement during the day. Assessment at the time with the longest duration of low-amplitude signals <40 μV in the filtered QRS complex terminus (LAS40) gave the highest receiver operating characteristics curve (area under the curve, 0.659) and the highest odds ratio (3.75; 95% confidence interval, 1.45–9.71; p=0.006) for predicting VT. In the multiple regression analysis, heart rate and noise were significant factors affecting LP parameters in the MI-VT and control groups. In the non-VT group, LP parameters were significantly influenced by noise and parasympathetic heart rate variability parameters such as logPNN50. Conclusions: For Holter-based LP measurements, test accuracy was higher when LP was measured at the time of the highest or worst value of LAS40. Changes in autonomic nervous system activity, including heart rate and noise levels, were factors influencing diurnal variability.

Published: June 2023

Post-extubation dysphagia (PED) can lead to serious health problems in critical ill patients, yet routine bedside screening may be lacking in many Intensive Care Units (ICUs), possibly due to limited awareness for this condition. This study aimed to establish baseline data on the current approaches, the status of perceived best practices to PED screening and treatment, as well as to assess awareness of PED. A nationwide cross-sectional, online survey was conducted of all adult ICUs in the Republic of Cyprus in June 2018. More than 85% of ICUs reported that there was no standard protocol indicating which patients should be screened for PED. Cough reflex testing and water swallow test were the most reported assessment methods used to confirm the presence of PED. Muscle strengthening exercises without swallowing and swallowing exercises were mostly used to treat dysphagia. Overall, 28.6% of the ICUs agreed that PED was common in their unit. We identified gaps in Greek Cypriot ICUs awareness and knowledge regarding PED screening and treatment. Comprehensive unit-based dysphagia education programs must be urgently im-plemented and interdisciplinary and collaborative work between nurses, intensivists and speech and language therapists is needed to address the situation and improve the quality of care pro-vided.

Hb Adana is a non-deletional α-thalassaemia variant, due to mutations in α1- or α2-globin codon 59 (αCD59) that produce unstable α-globin. Clinical appearance can range from silent carrier to blood transfusion reliance, hepatosplenomegaly, skeletal deformities, and spinal cord compression. Despite the importance of Hb Adana inheritance, this Hb variant is challenging to study since molecular tests are scarce and routine diagnosis can be missed. This study explored the distribution of Hb Adana among local high school students and evaluate the hematological parameters and haemoglobin analysis of Hb Adana in this region of Malaysia. This retrospective study included 13,721 blood samples from high school students enrolled in Malaysia's National Thalassaemia Screening Program at Hospital Raja Perempuan Zainab II (HRPZ II). Multiplex Gap PCR was used to detect deletional α-thalassaemia. Common non-deletional α-thalassaemia was detected using multiplex ARMS PCR. Evaluable data were retrieved from the HRPZ II database. Results: A total of 2327 subjects exhibited common deletional (n=1037, 44.6%) and non-deletional (n=1290, 55.4%) α-thalassaemia. Hb Constant Spring was the most frequent non-deletional α-thalassaemia. Thirty-one participants (1.33%) had αCD59α/αα and one (0.04%) had αCD59α/-α3.7. The 32 Hb Adana subjects were 87.5% Malay, and 12.5% Orang Asli. Additionally, seven cases of HbE/Hb Adana were discovered. The haemoglobin level in heterozygous Hb Adana ranged from mild anaemia to normal, 95.0 g/L to 153.0 g/L. The MCV and MCH were approximately 73 fL and 23 pg, respectively. Conclusions: We have denoted the distribution of alpha thalassaemia mutation patterns among high school students in Kelantan, Northeast Peninsular of Malaysia. Our observation showed Hb Adana was rarely uncommon in our region and the co-inheritance with an α-gene deletion generates α+-thalassaemia; with HbE, α0-thalassaemia. All heterozygous Hb Adana exhibited low MCVs and MCHs.

Like the most of crops, especially sugarcane needs to be kept upright until it is harvested. Because, lodging of sugarcane has a significant negative effect on cane yield and sugar content of sugarcane. To keep sugarcane upright earthing up is an utmost intercultural operation. In Bangladesh, most of the operations for sugarcane cultivation including earthing up are generally done in traditional method using human labor which increases production costs as well as reduces the income of sugarcane growers. So, a cost effective two-wheeled tractor (2WT) mounted earthing up machine was developed in Bangladesh Sugarcrop Research Institute (BSRI), Pabna to reduce drudgery and cost of sugarcane production. Field tests were conducted in experimental sugarcane field at BSRI and technical and economic performances of the developed earthing up machine were also carried out based on the field test. Average effective field capacity and field efficiency were found 0.16 ha/hr and 77.41 %, respectively for the developed earthing up machine. The earthing up machine was not found economically viable when it is used only for earthing up operation. Besides, when the 2WT was being used as the main driver for other activities including earthing up operation, then the earthing up machine becomes economically beneficial with net cash flow, net present value, internal rate of return, benefit-cost ratio and payback period of BDT 148497/ha, BDT 23184, 3%, 3.81:1 and approximately 1 year, respectively. On the contrary, considering cost of only earthing up tool without 2WT, then it was found economically beneficial with net cash flow, internal rate of return, net present value, benefit-cost ratio and payback period of BDT 16428/ha, BDT 3053, 4.7%, 2.71:1 and approximately 2 years, respectively. Since 2WT is commonly used for versatile farming purposes. Therefore, versatile use of 2WT as prime mover for other machines including earthing up machine can make earthing up machine economically viable and beneficial for sugarcane growers.

The dispersion properties of surface plasmon polaritons during propagation on metal wires with a dielectric coating in the terahertz frequency range are investigated theoretically. An analytical expression is obtained for a pulsed electric field from the solution of Maxwell equations taking into account high-order dispersion terms. The effect of the dielectric coating on the distortion of the pulse shape is analyzed. Unlike uncoated wire, the propagation of a surface plasmon pulses along a coated wire is highly dispersive. It is shown that the coating leads to the appearance of a long-chirped signal with a propagation of only a few millimeters, i.e. when a terahertz pulse propagates along a coated wire, it acquires a long oscillatory tail, the frequency of which depends on time.

Cosmetics have various characters, but there have been no studies which classified the properties of cosmetics based on their effects on skin-domesticated bacteria. In this study, we established an anaerobic culture and short-chain fatty acid measurement system using Staphylococcus epidermidis, a representative bacterium of indigenous skin bacteria. Furthermore, this system was used to extract and classify the characteristics of 9 cosmetics. Cosmetics containing ferments of rice and soy were clustered in the vicinity, although one cosmetic containing soy ferment was clustered distant from other similar cosmetics. Cosmetics from South Asia and those containing natural plant extracts were clustered in the vicinity. These results show that this method can be utilized as a cosmetics pattern map, and will provide a method to prevent growth of opportunistic bacteria.

The goal of this work is to develop a sustainable value chain of carbonaceous adsorbents that can be produced from the solid fibrous digestate (SFD) of biogas plants and further applied in integrated desulphurisation-upgrading (CO2/CH4 separation) processes of biogas to yield high purity biomethane. On this purpose, physical and chemical activation of the SFD derived biochar was optimised to afford micro-mesoporous activated carbons (ACs) of high BET surface area (590-2300 m2g−1) and enhanced pore volume (0.57-1.0 cm3g−1). Gas breakthrough experiments from fixed bed columns of the obtained ACs, using real biogas mixture as feedstock, unveiled that the physical and chemical activation conclude to different types of ACs which are sufficient for biogas upgrade and biogas desulphurisation respectively. Performing breakthrough experiments at three temperatures close to ambient it was possible to define the optimum conditions for enhanced H2S/CO2 separation. It was also concluded that the H2S adsorption capacity is significantly affected by restriction to gas diffusion. Hence, the best performance was obtained at 50 oC and the maximum observed in the H2S adsorption capacity vs the temperature is attributed to the counterbalance between adsorption and diffusion processes.

Background: Pteropodine (PT) is a component of some plants with potentially useful pharmaco-logical activities for humans. This compound has biomedical properties related to the modulation of the immune system, nervous system, and inflammatory processes. This study addresses the an-ti-inflammatory and antioxidant capacity of pteropodin in a murine model of arthritis and induced edema of the mouse ear. Methods: To evaluate the anti-inflammatory activity, we used the reversed passive Arthus reaction (RPAR), which includes the rat paw edema test, the rat pleurisy test, and a mouse ear edema model. The antioxidant effect was evaluated by determining the myeloperoxidase enzyme activity. Results: PT showed an anti-inflammatory effect in the different specific and non-specific tests. We found a 52 to 74% of inhibitory effect of PT in the rat paw edema test, 52% of reduction of the pleural exudate volume, and low neutrophil count (28%), when compared to the control group. We also found a 81% of inflammatory inhibition of the ear edema, and a significant myeloperoxidase enzyme inhibition by the three doses of PT. Conclusions: PT exerted a potent an-ti-inflammatory effect in the acute inflammation model in rodents.

Benefits of baby swimming have been established, but there is limited knowledge about the methodologies used by practitioners. To address this knowledge gap, this study aimed to categorize and classify the equipment and environmental used in baby swimming programs worldwide. A descriptive categorical content analysis approach was employed to analyse videos of baby swimming programs obtained from YouTube. The framework created was validated for interrater reliability, and a pilot study was conducted to classify videos from different countries based on the equipment and environment used. Results indicated that the physical environments observed were pool tanks and swimming pools with and without depth reduction zones, while the equipment used included assistive devices, toys, and clothes. This study represents a significant first step in the development of a comprehensive tool to systematize and characterize the methodologies used in baby swimming programs globally.
Monitoring Braided River-Bed Dynamics at Sub-Event Time Scale Using Time Series of Sentinel-1 SAR Imagery

Published: June 2023

Remote sensing plays a central role in the assessment of environmental phenomena and has increasingly become a powerful tool for monitoring shorelines, rivers morphology, flood waves delineation and floods assessment. Optical based monitoring and characterization of river evolution at long time scales is a key tool in fluvial geomorphology. However, the evolution occurring during extreme events is crucial for the understanding of the river dynamics under severe flow conditions and requires the processing of data from active sensors to overcome cloud obstructions. This work proposes a cloud-based unsupervised algorithm for the intra-event monitoring of river dynamics during extreme flow conditions based on time series of Sentinel-1 SAR data. The method allows the extraction of multi-temporal series of spatially explicit geometric parameters at high time and spatial resolutions, linking them to the hydrometric levels acquired by reference gauge stations. Intra-event reconstruction of inundation dynamics has led to the estimation of the relationship between hydrometric level and wet area extension and the assessment of bank erosion phenomena. Time series of SAR acquisitions, provided by Copernicus Sentinel-1 satellites, were analyzed to quantify changes in the wet area of a reach of the Tagliamento river under different flow conditions. The algorithm, developed within the Python-API of GEE, first empowers the Sentinel-1 images with the hydrometric level, then involves radiometric slope correction and speckle noise filtering. The Otsu method is then used for image segmentation leading to a water and dry land binary classification. Results support many types of analysis about river dynamics, including morphological changes, floods monitoring and relief efforts and bio-physical habitat dynamics. The results encourage future advancements and applications of the algorithm, specifically exploring SAR data from ICEYE and Capella Space constellations, which offer significantly higher spatial and temporal resolutions compared to Sentinel-1 data.

Vernacular architecture constitutes a rich source of information and ancestral knowledge that can become a key resource for sustainable development through its passive design strategies, which effectively respond to local climatic and weather conditions using locally sourced materials for the construction of its supporting structure and enveloping elements, as well as spatial organization and the incorporation of a buffer area (patio) that optimize the use of renewable resources. This qualitative study analyzes a traditional housing typology with a central patio located in the Historic Center of Azogues city, Ecuador, to evaluate its interior thermal comfort through in-situ monitoring in the different building spaces. Using the open-source software Open Studio and EnergyPlus, a simulation model was built to assess the annual thermal performance of the house. Field records were used to verify the effectiveness of the strategies that respond to the climatic conditions of the area. The analysis carried out on the passive strategies used in the selected house with regard to natural ventilation, solar protection, and thermal insulation, which depend on various aspects of the building, such as its location, internal space arrangement, design of openings (doors and windows), among others. The thermal simulations reveal that the traditional house located in the Historic Center of Azogues city is well adapted to the local climate, although interior thermal comfort is not entirely satisfactory.

Abstract
Background: Parkinson's disease (PD) is a neurodegenerative disorder featured with motor and non-motor deficits. Using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced dopamine neuron degeneration has been widely used to produce reliable animal models of the PD. However, most of previous preclinical studies focused on the motor dysfunctions, few non-motor symptoms were evaluated. So far there is a lack of comprehensive investigation of the non-motor symptoms in animal models.
Objectives: In this study, we aim to use a battery of behavioral methods to evaluate the non-motor symptoms in MPTP-induced non-human primate PD models.
Methods: Cognitive functions, sleep and psychiatric behaviors were evaluated in MPTP-treated cynomolgus monkeys. The tests consisted of delayed matching-to-sample (DMTS), physical activity monitor (PAM), apathy feeding task (AFT), human intruder test (HIT), novel fruit test (NFT) and predator confrontation test (PCT). In addition, we tested whether the dopamine receptor agonist pramipexole (PPX) will improve these non-motor symptoms.
Results: The present results show that the MPTP-treated monkeys exhibited cognitive deficits, abnormal sleep, and anxiety-like behaviors as compared to the control monkeys. These symptoms were relieved partially by PPX.
Conclusions: These results suggest that MPTP-induced PD monkeys displayed non-motor symptoms that were similar to those found in PD patients. PPX treatment showed moderate therapeutic effects on these non-motor symptoms. This battery of behavioral tests may provide a valuable model for future preclinical research.
