Abstract

Introduction: The purpose of the study was the calibration of Gafchromic films in clinical interventional radiology conditions and the assessment of the influence of dose range, the shape of the fitting curve, and its practical application. The aim of the work was to show how practically perform calibration in a wide range of doses.

Material and methods: Gafchromic XR–RV3 films were included in the study. The calibration was performed for A and B film series separately. Doses from the range of 0 – 8 Gy were used. Film dosimeters were read out in reflective mode with a commercial flatbed scanner.

Results: Among various degrees of a polynomial function, the best fit, which fulfilled the chosen criterion of 95% agreement between measured and reconstructed doses and simple equation criterion, was observed for third-degree polynomial. The fitting curve where the dose is the function of optical density (logMPV) was demonstrated to be more precise than the fitting curve based on MPV only. To minimize the difference between dose absorbed by the film and dose reconstructed from the fitting curve below 5% it is necessary to divide the calibration range of 0 – 8 Gy into two subranges for use in interventional radiology. This difference was set at a maximum level of 3.8% and 1.9% for the lowand high-dose range, respectively. Each series of films may have a slightly different calibration curve, especially for the low dose range. A deviation of up to 36% between two batches of Gafchromic film was observed.

Conclusions: For the third-degree polynomial fitting function (one of the recommended in the literature) calibration should be done into low and high dose ranges and for each batch separately. A systematic error higher than 20% could be introduced when the fitting curve from one film batch is applied to the other film batch.

Abstract
Spiroid wingtip devices (WD) offer a promising way of improving the lift drag ratio of UAVs, but may on the other hand lead to negative aerodynamic interference of the wing with the WD and deterioration of the aerodynamic characteristics as compared to a wing without the WD. Determining the influence of the geometric parameters of a spiroid WD on aerodynamic wing characteristics, however, remains an understudied field. In our study, we investigated the influence of the following geometrical parameters on wing aerodynamic characteristics with WD: area, radius, camber angle, constriction, and pitch of the spiroid. We found that the positive effect of the WD is present at a relative radius > 0.05, as well as with an increase in the lift coefficient C

L
as a result of an increase in the proportion of inductive resistance. For example, with the Reynolds number Re = 2.1×105 for a rectangular wing with an aspect ratio θ = 5.12 equipped with a spiroid WD with =0.15 the quality gain is almost 10% at C

L
= 0.5, and at C

L
= 0.7 is almost 20% and at C

L
= 0.7 – almost 20% compared to a wing without WD. Moreover, we found that a change in the camber angle WD θ provides an increase in the derivative of the lift coefficient with respect to the angle of attack in the range from θ = 0° to θ = 130°. By changing the camber angle, it is possible to increase the lift drag ratio of the layout up to 7.5% at θ = 90° compared to θ = 0° at the Reynolds number Re = 2.1×105. From the point of view of ensuring maximum lift drag ratio and minimum inductive drag, the angle θ = 90° is the most beneficial.
STUDENT AND INSTRUCTOR EXPERIENCE USING COLLABORATIVE ANNOTATION VIA PERUSALL IN UPPER YEAR AND GRADUATE COURSES
Authors: D’Entremont Agnes G. , Eyking Adrianna 
Published: July 2021

Perusall is a collaborative annotation platform designed for pre-readings in a flipped classroom, but can also be used for stand-alone, asynchronous reading discussion components of courses. We examine the use of Perusall as a social constructivist learning tool in two upper year/graduate courses in Mechanical Engineering. Perusall was used to replace in-class discussion of readings during the shift to online teaching. Data was collected from student surveys and from the student and instructor annotations themselves. Annotations were coded for content, and examined for factors such as upvoting. We found substantial engagement from students, with collaborative annotation providing opportunities for: correction of misunderstanding; linking concepts from the course and between readings; discussing larger issues around research and research writing; sharing background information among peers; and critically analyzing the readings. Students reported deeper learning than in typical in-class discussions of readings; however, they also noted that annotation required much more time. Overall, collaborative annotation appears to be an effective method for course reading discussion.

Authors: Mahfud Mahfud , Rizanizarli Rizanizarli 
Published: July 2021

Even though Law Number 23 of 2004 concerning on the Elimination of Domestic Violence was promulgated fifteen years ago, the number of domestic violence against women has not significantly decreased. The Law has not set concrete actions that may fall under the domestic violence that can be punished, particularly in terms of sexual abuse psychological violence, and negligence in household towards women. This research aims to analyze domestic violence against women in this Law and the conducts that are considered to be domestic violence which is commonly found in daily life in Indonesia. A purely qualitative research method encompassing document analysis of key documents in Indonesia and the Anti-Domestic Violence Law 2004 is adopted in this paper. The research reveals that This Law is particularly protecting women from household violence in Indonesia. The law has recognized physical violence, sexual violence, psychological violence, and negligence as sorts of domestic violence against women in household although it might find difficult to enforce the law when dealing with marital rape regarding lack of reports from victims and polygamy concerning circumstances that can be used to criminalize the perpetrators.

Manual Therapy: Always a Passive Treatment?
Authors: Rhon Daniel I. , Deyle Gail D. 
Published: July 2021

Synopsis The use of manual therapy as an intervention has garnered intense debate, one that is often mired in a straw-man argument that manual therapy is a purely passive intervention. When passive interventions are equated with low-value care, it is easy to deride manual therapy as low-value care. However, manual therapy describes a wide variety of treatments, some with passive components and some that are primarily passive in certain scenarios. But manual therapy can be an integral part of highly active treatment strategies. We implore investigators to describe manual therapy interventions in sufficient detail so that they can be reproduced and thereby help the end users of research (including clinicians) to better assess the value of such interventions. This Viewpoint challenges the assumption that manual therapy is always a passive treatment of low value. J Orthop Sports Phys Ther 2021;51(10):474–477. Epub 1 Jul 2021. doi:10.2519/jospt.2021.10330

Objectives:
Radiographic reference lines, angles, and measures comprise the foundation for accurate evaluation and surgical planning of orthopedic surgeries, especially when it comes to foot and ankle deformities. To date, no study has evaluated the average parameters for foot and ankle radiography in the Saudi population. This study aimed to establish reference values of foot and ankle angles for the general Saudi population.

Methods:
We included 100 participants (200 feet) in this study, with 50 males and 50 females aged 21–30 years. We recruited subjects who had no history of foot or ankle pain, surgery or fracture, no evidence of ligamentous laxity, and no history of systemic disease. Bilateral anterior-posterior (AP) and lateral weight-bearing radiographs were obtained using standardized angles. A total of 19 angles on AP and 9 angles on lateral radiographs were evaluated. Radiographic parameters were compared between genders.

Results:
A total of 400 radiographs from 200 normal feet were evaluated. The mean ± SD age of the subjects was 22.7±1.7 years. Statistically significant differences in mean radiographic parameters were found between males and females in both radiographic projections.

Conclusion:
Significant variation exists between the normal foot and ankle reference angles between the Saudi population included in our study and other ethnicities. Moreover, significant differences are found between genders in our study. Considering the lack of other studies involving the Saudi population, the results of this study can help serve as a reference when evaluating Saudi patients.
Cranial nerve function after cerebellopontine angle meningiomas removal
Authors: Sirko Andrii H. , Malyi Rostislav R. 
Published: July 2021

Objective. To analyze cranial nerves (CN) dysfunction incidence in cerebellopontine angle (CPA) meningiomas removal depending on topographic and anatomical tumor location type and define the ways to reduce CN dysfunction incidence and severity.
Materials and methods. The study included 30 CPA meningioma patients operated on in the clinic over a 10-year period (from 2010 to 2020 inclusive). Tumor characteristics, the degree of extent (including matrix location, particularly in relation to the internal auditory canal (IAC), jugular foramen (JF), and Meckel’s cave), and supratentorial extension were assessed. The tumors were divided into 5 groups according to the classification of Nakamura et al. Particular attention was paid to the presence and severity of pre- and postoperative cranial nerves dysfunction.
Results. Different groups of CPA meningiomas in terms of the presence of a new CN neurological deficit were compared in the study. CN VII dysfunction was more frequently detected in group 2 — meningiomas extending to IAC, which was 54.5% of all observed tumors in this group vs. premeatal tumors, where new CN VII deficit was 20%, in group 1. At the same time in groups 3, 4, and 5 there was no new CN VII deficit.
Conclusions. The most frequent symptoms in patients of all groups were dizziness, headache and unsteady gait. Of all the symptoms, only unsteady gait and hearing impairment were more common in patients in group 2, however the differences were statistically insignificant (p = 0.135 and p = 0.268, respectively). Trigeminal nerve and auditory nerve were most commonly affected. Auditory nerve lesions were more often detected in patients of group 2 than in patients of other groups, however, the differences were statistically insignificant (p = 0.268). In general, there were no statistically significant differences between the groups in terms of the incidence of various symptoms and the incidence of CPA cranial nerve damage.
An Approach to the Management of Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.
Authors: Bouhadana David , Sadri Iman 
Published: July 2021

Benign prostatic hyperplasia (BPH) is a condition that affects up to 50% of men over the age of 50; the condition’s prevalence increases with age, particularly after the age of 40. BPH can lead to lower urinary tract symptoms (LUTS) which can have a significant negative impact on health-related quality of life (HRQoL). Men presenting with a gradual onset of LUTS are often suspected to have BPH. However, the clinician must recognize that LUTS possess many different aetiologies. This article aims to provide medical students with a stepwise approach to the diagnosis and management of LUTS that are secondary to BPH. The outlined approach describes the differential diagnoses, required investigations, and management-related details for LUTS that are secondary to BPH. This approach is based off of relevant Canadian, American, and European urological association guidelines.

O artigo apresenta as configurações da cultura escolar de uma escola civil militar que atende ao Ensino Médio, em Cuiabá-MT. É um estudo qualitativo e descritivo que teve como instrumentos de pesquisa fontes documentais, observações e entrevistas semiestruturadas. As discussões têm assento na socioantropologia sobre os desafios da escola e do Ensino Médio ao atender as juventudes; como a cultura escolar lida com a diversidade juvenil; como o projeto pedagógico se vincula aos contextos de vida dos alunos. Compreendeu-se que os projetos de vida dos “jovens alunos” são marcados por incertezas em relação Ã proximidade com a adultez e a terminalidade dos estudos e a importância de investigações sobre as relações entre os jovens, a escola e o Ensino Médio.
microemancipação por meio do ensino superior em administração
Authors: Paschoal Capucho Pablo Henrique , Borim-de-Souza Rafael 
Published: July 2021

O ensino em Administração é tecnocrático e cúmplice de imposições capitalistas que alienam os indivíduos conforme desígnios do mercado. O esquivo a uma formação humanista, reflexiva e crítica prejudica a constituição de uma compreensão em relação a uma realidade que é socialmente construída a partir de uma capacidade de agência silenciada. O objetivo deste estudo teórico é abordar o conhecimento como meio de microemancipação perante as formas de alienação que permeiam a sociedade e a formação dos administradores. Propõe-se que o conceito de microemancipação, por intermédio da razão crítica, ilumine a consciência do administrador quanto Ã s consequências de suas intervenções socioeconômicas.

O artigo se propõe a compreender o contexto da gestão gerencial, enquanto política pública, suas características e influências no sistema educacional e no trabalho do coordenador pedagógico. Originário de uma pesquisa bibliográfica, o estudo evidencia que a gestão gerencial imprime ao trabalho do coordenador pedagógico políticas públicas de responsabilização pela articulação da prática e dos resultados da escola; e, ao exigir líderes executores e não reflexivos, o sistema gerencial tende a transformar o coordenador em um mero executor das ideologias neoliberais sem espaço e condições para superar as concepções ideológicas dominantes.
