Authors: Da Silva Ribeiro Leni , Xavier da Silva Mattos Hellen Cristina 
Published: February 2023

O presente artigo propõe contribuições para a importância de considerar a relação da trajetória escolar com a prática docente, baseada na perspectiva teórica da Relação com o Saber. Consideramos que os estudos de trajetórias nos permitem considerar os elementos sociais que compõem os sujeitos e que influenciam no seu desempenho na escola. O nosso objetivo geral, portanto, é compreender os estudos sobre a trajetória escolar e as suas contribuições para a prática docente. Para isso, realizamos um estudo da arte com as pesquisas na área “trajetória escolar”, a fim de caracterizar e identificar as suas contribuições para a prática docente. A pesquisa foi desenvolvida a partir dos resumos de artigos publicados em periódicos científicos, os quais foram quantificados e identificados para realizar o mapeamento da área de estudo. Como resultados, verificamos que poucos estudos dessa área temática fazem uma relação direta com as práticas pedagógicas. Os artigos que nos ajudaram a ter essa compreensão se referem aos desdobramentos de uma relação de mão-dupla: a trajetória produz efeitos na escola ao mesmo tempo que essa instituição impacta os percursos dos estudantes. Consideramos que os estudos de trajetórias escolares indicam como o contexto social influencia o processo de aprendizagem, pois os alunos são sujeitos que estão tendo relações com o saber o tempo todo, com as outras pessoas ao seu redor e com o mundo. Assim, o professor deve sempre lembrar que seus alunos são sujeitos que têm histórias e que a abordagem de ensino terá maior significado se considerar os percursos que os discentes estão trilhando.

Authors: Ritonga Daniel , Fitrian Achmad , Hendro Gatut 
Published: February 2023

The research will discuss the execution of industrial relations court decisions with permanent legal force, aiming to reveal and analyze how the process of implementing industrial relations court decisions with permanent legal force and what factors hinder the execution of industrial relations court decisions with permanent legal force. This is a literature study using normative legal research.
The data collected by library research, namely by the study of written information about the law that comes from various sources and is widely published and is needed in normative legal research. The findings highlight that the procedure for the execution of industrial relations court decisions that have permanent legal force has not been explicitly regulated in Law Number 2 of 2004 concerning Industrial Relations Dispute Settlement. However, Industrial Relations Dispute Settlement confirms that the Industrial Relations Court applies procedural law applicable to civil procedural law within the General Courts as stated in Article 57 of Industrial Relations Dispute Settlement. The lack of good faith on the part of the losing party to voluntarily carry out their obligations as stated in the verdict is one of the factors impeding the execution of the Industrial Relations Court's decision, which has permanent legal force. In addition, it is difficult for the winning party, in this case the workers, to determine which company assets can be executed against the losing party, and the execution cost is too high for the court to issue an execution order.

Metal nanoparticles as a category of nanomaterial are receiving interest due to their wide range of applications including in biomedical fields. Among these nanoparticles, silver nanoparticles are the most extensively studied for medical applications because they have been proven to exhibit excellent activity against a wide range of medically significant pathogenic microorganisms, including bacteria, viruses, fungi, and yeasts. In this work, silver nanoparticles were biogenically synthesized using the stem bark extract of Stereospermum kunthianum Cham as capping agent. Physicochemical properties, antioxidant activity, antimicrobial properties and in vitro cytotoxicity of the synthesized AgNPs were studied following standard procedures. UV-Vis studies show broad absorbance peak of the nanoparticles between 430 and 450 nm, SEM image shows that some of the synthesized nanoparticles are near spherical shape with many of the particles appear to have irregular shapes while the material average crystalline size from the XRD analysis was 27.878 mm. The synthesized AgNPs exhibits moderate antioxidant activity with IC50 value of 124.84 μg/mL. Among the microorganism tested, the AgNPs shows more activity against Staphylococcus aureus than Salmonella typhi and Candida albicans. Brine shrimp lethality test of the synthesized AgNPs indicates some level of cytotoxicity with LC50 of 461.850 μg/mL. using biological materials as reducing agents remains best green approach for the synthesis of silver nanoparticles.

Published: February 2023

Introduction: Granuloma annulare (GA) is a non-infectious granulomatous disease that can affect children and adults. Although many studies have been conducted adult GA patients, the literature on pediatric GA cases is limited.
Objectives: Therefore, this study aimed to examine the demographic, clinical, and pathological features of pediatric GA cases.
Methods: This study was performed retrospectively in a single-center tertiary dermatology hospital. Demographic characteristics and clinical and histopathological features were recorded.
Results: Forty-one participants were included in this study, of which 66% were female. The mean age was 3.8 ± 2.6 years, and the mean lesion duration was 7.5 ± 10.3 months. The involvement of 78% of the patients was localized, and the remaining 22% was generalized. Asthma (30%) was the most common comorbid disease. Histopathological examination was performed on twenty-one patients, and the infiltrate pattern was interstitial in 71% of the cases and palisadic in 29%. Generalized distribution, trunk involvement, and concomitant disease tended to be higher in patients with an interstitial pattern than in those with a palisadic pattern.
Conclusions: Atopy and asthma should be questioned in pediatric GA cases. There are differences between involvement, distribution, concomitant disease, and histopathological patterns, which may indicate differences in pathogenesis.
What Do Patients Want To See On Social Media? Evidence From A Two-Year Experiment
Authors: Barrutia Leire , Vega-Gutiérrez Jes´ús , Santamarina-Albertos Alba 
Published: February 2023

Introduction: Dermatological information on social media is dominated by misleading and potentially harmful content from nonexperts. Literature suggests that, to address this issue, dermatologists should develop an online presence. However, successful presence of dermatologists on social media has been criticized for focusing on cosmetic dermatology and not representing the broad spectrum of the specialty.
Objectives: The aim of this study was to systematically analyze which dermatological topics interest the public most, and to find out whether it is feasible for a dermatologist to become influential on social media while presenting all dermatological topics equally.
Methods: The study was performed on an educational dermatology YouTube channel. The 101 videos published in a two-year period were divided into cosmetic (51 videos) and medical dermatology (50 videos). Student’s t-test was conducted to determine whether there were significant differences in views. Medical dermatology videos were then classified into three categories: Acne, facial dermatoses (excluding acne) and other dermatological diseases. A Kruskal-Wallis test was used to compare these three categories and cosmetic dermatology.
Results: When comparing cosmetic and medical dermatology, no significant differences were found. When comparing the four categories, cosmetic dermatology and acne were found to generate significantly more views that other dermatological diseases.
Conclusions: The public seems to be particularly interested in cosmetic dermatology and acne. This might make it challenging to become successful on social media while presenting a balanced portray of dermatology. However, focusing on popular topics can provide a real chance to be influential and protect vulnerable people from misinformation.

Published: February 2023

The meteorological and hydrological drought indices are mostly applying as a tool for observing changes in drought situations. In the present research work, evaluated the performance of two modified meteorological drought indices i.e. modified standardized precipitation index (SPIe) and modified recoinnaissance drought index (RDIe) and hydrological drought indices i.e stream-flow drought index (SDI). The effective precipitation was used instead of precipitation for modification of meteorological drought indices. The assessment of drought trends at multi-temporal such as 1, 3, 6 and 12 months was done by using popular Mann-Kendall test and the probability and return period of occurrence of severe and extreme drought condition of the meteorological and hydrological drought events. Finally results were non-significant trend (either positive or negative) at 95% confidence limit and the 43 years reoccurrence interval of extreme meteorological drought for Latur and Parabhani districts, the 10.75, 21.5 and 14.33 years return period of severe meteorological drought for Latur, Nanded and Parabhani districts. Also, the 18, 18 and 43 years reoccurrence interval of severe hydrological drought for Latur, Nanded and Parabhani districts was calculated.

Authors: Katsimpris Andreas , Moleron Maria , Karamaounas Aristotelis , Kandarakis Stylianos 
Published: February 2023

Aims: To report a case of very late-onset capsular bag distention syndrome (CBDS) 8 years after uncomplicated cataract surgery treated with Neodymium: Yag (Nd: Yag) laser posterior capsulotomy.
Presentation of the Case: A 76-year-old female patient without any systemic or ocular disorders, presented with progressive blurry vision in her right eye (RE) over the last 1 year. Best-corrected visual acuity (BCVA) was 6/9 in the right eye and 6/6 in the left eye. Manifest refraction revealed a 0.5 diopters myopic shift in her RE compared to her last ocular examination 2 years ago. Scheimpflug photograpgy and slit-lamp examination were utilized to make the diagnosis of CBDS, which was successfully treated with Nd: Yag laser posterior capsulotomy. At day 1 post-capsulotomy the BCVA of her RE improved to 6/6 with a 0.5 diopters hyperopic shift which was consistent with a 0.13 mm post-capsulotomy increase in the anterior chamber depth, as documented by the Scheimpflug images.
Discussion and Conclusion: Late-onset CBDS can manifest after a considerable time period following cataract surgery and Scheimpflug imaging can be a useful aid for a precise diagnosis and documentation of the treatment.

Published: February 2023

The study was undertaken to determine the available micro-nutrient status of the Bhandara tehsil of Maharashtra with the help of GPS-based one hundred-and-five soil samples during the period of 2021-2022 from paddy growing fields. Samples were analyzed at the Soil Science and Agricultural Chemistry Section, College of Agriculture, Nagpur. The results revealed that soils were clay loam to sandy clay loam in texture. The study area was slightly acidic to slightly alkaline and non-saline in reaction. The mean values of 0.42 mg kg-1, 5.44 mg kg-1, 6.39 mg kg-1, 0.98 mg kg-1, and 0.90 mg kg-1 for Zn, Fe, Mn, Cu and B respectively, were recorded. The soil nutrient index values showed that available Zn was low; available Fe was moderate; available Mn and B were moderately high; and available Cu was high. The farmers of the study area mostly adopt improper nutrient management practices which might have resulted in poor fertility status in the area. Taking these things into consideration, a data-driven Decision Support System (DSS) on micronutrient management in soil has been given. To address this problem, farmers of Bhandara tehsil may use micronutrient fertilizers or implement soil management practices that promote the uptake and availability of micronutrients to plants.
Quantifying and Interpreting the Prediction Accuracy of Models for the Time of a Cardiovascular Event—Moving Beyond C Statistic

Published: February 2023

ImportanceFor personalized or stratified medicine, it is critical to establish a reliable and efficient prediction model for a clinical outcome of interest. The goal is to develop a parsimonious model with fewer predictors for broad future application without compromising predictability. A general approach is to construct various empirical models via individual patients’ specific baseline characteristics/biomarkers and then evaluate their relative merits. When the outcome of interest is the timing of a cardiovascular event, a commonly used metric to assess the adequacy of the fitted models is based on C statistics. These measures quantify a model’s ability to separate those who develop events earlier from those who develop them later or not at all (discrimination), but they do not measure how closely model estimates match observed outcomes (prediction accuracy). Metrics that provide clinically interpretable measures to quantify prediction accuracy are needed.ObservationsC statistics measure the concordance between the risk scores derived from the model and the observed event time observations. However, C statistics do not quantify the model prediction accuracy. The integrated Brier Score, which calculates the mean squared distance between the empirical cumulative event-free curve and its individual patient’s counterparts, estimates the prediction accuracy, but it is not clinically intuitive. A simple alternative measure is the average distance between the observed and predicted event times over the entire study population. This metric directly quantifies the model prediction accuracy and has often been used to evaluate the goodness of fit of the assumed models in settings other than survival data. This time-scale measure is easier to interpret than the C statistics or the Brier score.Conclusions and RelevanceThis article enhances our understanding of the model selection/evaluation process with respect to prediction accuracy. A simple, intuitive measure for quantifying such accuracy beyond C statistics can improve the reliability and efficiency of the selected model for personalized and stratified medicine.
Evolving practice in global healthcare: Remote physics support for low‐ and middle‐income countries

AbstractThe COVID‐19 pandemic has disrupted traditional onsite support for radiotherapy clinics in low‐ and middle‐income countries (LMIC). Clinics there have struggled to commission new techniques and receive onsite training for their staff. We sought to evaluate whether an offsite approach could fill this gap at a clinic in Jordan by requesting a clinical audit and attempting to commission volumetric modulated arc therapy (VMAT). Over 13 months, a consultant provided remote support for a radiotherapy center that had already obtained treatment equipment and licenses. The consultant began by conducting a virtual audit, using a remote login to the center's R&V and TPS, to identify any gaps in the clinical workflow. Suggestions for improving the clinical workflow were proposed, and change implementation was tracked through emails, social media apps, and video conferencing. An extensive table outlined the commissioning process, including all measurements to be done. Social media apps and shared documents were used to track measurements and analysis. The lack of person‐to‐person interaction in this new remote‐support ecosystem created conflicts; we have highlighted some of these, as well as their resolution and the lessons learned from them. The virtual audit identified gaps categorized as machine QA, treatment plan review, and treatment delivery processes. Following the implementation of the proposals, motion management was added, and machine QA became more comprehensive. VMAT was commissioned using the reports of the AAPM and the IAEA. The main challenges for remote support were time difference, establishing an appropriate form and frequency of communication, tone of voice used in messages, and buy‐in from local staff. This evolving practice will enable medical physicists to use modern, multimodal remote communication pathways to effectively transfer knowledge to centers in LMICs. The audit–proposal–improvement pathway for remote support can be incorporated to help others while avoiding the pitfalls we faced.

AbstractIn this study, a reactive oxygen species (ROS)‐responsive hydrogel sensor (PD/MnO2 hydrogel) is developed that can efficiently detect senescent cells. Using immature murine articular chondrocytes with serial passages, the sensor can identify small interfering RNA (siRNA) knockdown of peroxisome proliferator‐activated receptor‐alpha (PPARα) based on the concentration of ROS in cells, simultaneously maintaining its balance via scavenging activity to prevent cartilage degradation in osteoarthritis (OA). The hydrogel sensor exhibits a change in electronic properties, with a distinct resistance from 201.9 kΩ for P0 to 362.9 kΩ for P3, and fluorescence off/on performance with an increase in passaging time. In vitro investigation using PPARα‐specific siRNA reveals a correlation between pressure sensitivity and senescent activity, wherein an elevation in observed signal occurred (41.5%). In vivo analysis reveals significant decrease in degradation of the cartilage of both young, 3 months old aged, 18 months old, and PPARα−/− mice compared to PPARα+/+ mice based on safranin O stains. The expression level of interleukin‐1β is reduced in the cartilage of aged PPARα−/− mice after implantation with hydrogel, indicating the potential of PD/MnO2 hydrogel as a therapeutic modality against OA.

AbstractIntroductionMild to moderate exercise may decrease Alzheimer's disease (AD) risk, but the effects of vigorous, regular physical exercise remain unclear.MethodsTwo patients with initial diagnoses of amnestic mild cognitive impairment (MCI) demonstrated positive AD biomarkers throughout 16 and 8 years of follow‐up, with final diagnoses of mild AD and amnestic MCI, respectively.ResultsPatient 1 was diagnosed with amnestic MCI at age 64. Neuropsychological testing, magnetic resonance imaging (MRI), fluorodeoxyglucose–positron emission tomography (FDG‐PET), amyloid imaging PET, and cerebrospinal fluid (CSF) biomarkers during follow‐ups remained consistent with AD. By age 80, progression was minimal with Montreal Cognitive Assessment (MoCA) 26 of 30. Patient 2 was diagnosed with amnestic MCI at age 72. Neuropsychological testing, MRI, FDG‐PET, and amyloid imaging PET during follow‐ups remained consistent with AD. At age 80, MoCA was 27 of 30 with no clinical progression. Both patients regularly performed vigorous, regular exercise that increased after retirement/work reduction.DiscussionVigorous, regular exercise may slow disease progression in biomarker‐positive amnestic MCI and mild AD.
Fourier spectral‐timing techniques for the study of accreting black holes
Authors: Ingram Adam 
Published: February 2023

AbstractThe X‐ray signal from active galactic nuclei and black hole (BH) X‐ray binaries is highly variable on a range of timescales. This variability can be exploited to map the region of interest close to the BH, which is far too small to directly image for all but two BHs in the Universe. Spectral‐timing techniques provide causal information by combining timing and spectral information. I present a brief review of such techniques, focusing on two examples: X‐ray reverberation mapping and phase‐resolved spectroscopy of low‐frequency quasi‐periodic oscillations (LF QPOs). The former provides a means to diagnose the accretion geometry and measure parameters such as BH mass, and the latter gives perhaps the best constraints we currently have as to the enigmatic LF QPO mechanism.
