Associer les formateurs à la conception de ressources pour leur propre formation : un essai d’analyse d’une coopération orientée-activité
Authors: Mouton Jean-Claude , Flandin Simon
Published: March 2021

Sur la base d’une convention entre l’Institut français de l’Éducation (IFÉ) et l’entreprise EDF, une équipe constituée de représentants des deux institutions est intervenue pendant une année au sein de l’entreprise pour la conception d’un environnement numérique destiné à la formation de formateurs. Menée dans une approche ergonomique, l’intervention a demandé plusieurs ajustements (cadres théoriques, cultures des acteurs, commande et demande, pertinence et acceptabilité des méthodes) et a initié et outillé une co-analyse de l’activité des formateurs. Les épisodes les plus significatifs, leur analyse et le modèle d’activité produit sont décrits, ainsi que la manière dont ils ont informé la conception. Nous discutons en conclusion des conditions requises à l’instauration et à l’entretien d’un rapport ouvert entre conception, formation et recherche dans ce type d’intervention.
Une perspective d’éducation tout au long de la vie centrée sur l’activité humaine et positionnée dans le courant des Humanités Numériques
Authors: Poizat Germain , Gaillard Vincent , Durand Marc
Published: March 2021

Le recours à l’analyse de l’activité dans une perspective d’éducation impacte le travail des formateurs, notamment du fait qu’elle leur procure des instruments de conception et d’action nouveaux. Cela vaut pour les formateurs dans leurs pratiques quotidiennes ; cela vaut aussi pour les formateurs-chercheurs d’une équipe de recherche. Cet article présente une réflexion relative à un impact majeur au sein du programme de recherche cours d’action porté par cette équipe, qui est l’extension des visées de formation professionnelle vers celles d’une « éducation tout au long de la vie » (ELV). Concevoir une ELV centrée sur l’activité humaine et son analyse, suppose de se donner un idéal de l’homme éduqué, et de se préoccuper des pratiques sociales réelles, tenues pour des références, des supports et des cibles pour les transformations des activités humaines visées en formation. Cette définition implique a) une conception éducative holiste qui respecte le caractère global, pluridimensionnel et singulier de l’activité humaine, sa dynamique historique, son inscription culturelle, sa continuité individuelle-sociale, et sa permanente auto-construction ; b) un positionnement de cette perspective d’ELV dans le courant des Humanités Numériques ; c) une inscription du programme de recherche cours d’action dans une approche d’anthropotechnologie éducative.

Generally, radiation oncology applies evaluation and prediction in medical imaging and diagnosis, specifically for contouring organs, which results in the production of the clinical target volume (CTV) that corresponds to disease risk and organ exclusion. Medical physicists contour organs and combine computed tomography (CT) scans to digital imaging and communications in medicine (DICOM) radiation therapy (RT) to assist physicians for diagnosing tumors and calculating the dosages in treatments including radiation and chemotherapy. Thus, to generate RT images with high accuracy, this paper proposes a new Generator Adversarial Network (GAN) for RT images called radiation therapy GAN (RTGAN). We combine multiple loss functions with synthetic similarity DICOM-RT images and compare the results with Pinnacle, a radiation oncology treatment planning system. Further, we evaluate the method to get a score of 0.984 in structured similarity (SSIM) and 31.26 in peak signal-to-noise ratio (PSNR) and find that it costs 0.058 s to finish contouring one CT image. The proposed method is applied and tested in the department of radiation oncology at the Chung Shan Medical University Hospital, and the results are similar to the ground truth images. Thus, it not only effectively reduces the false-positive rate but also makes a breakthrough in medicine.

Published: March 2021

The tremendous amount of data generated through IoT can be imbalanced causing class imbalance problem (CIP). CIP is one of the major issues in machine learning where most of the samples belong to one of the classes, thus producing biased classifiers. The authors in this paper are working on four imbalanced datasets belonging to diverse domains. The objective of this study is to deal with CIP using oversampling techniques. One of the commonly used oversampling approaches is synthetic minority oversampling technique (SMOTE). In this paper, the authors have suggested modifications in SMOTE and proposed their own algorithm, SMOTE-modified (SMOTE-M). To provide a fair evaluation, it is compared with three oversampling approaches, SMOTE, adaptive synthetic oversampling (ADASYN), and SMOTE-Adaboost. To evaluate the performances of sampling approaches, models are constructed using four classifiers (K-nearest neighbour, decision tree, naive Bayes, logistic regression) on balanced and imbalanced datasets. The study shows that the results of SMOTE-M are comparable to that of ADASYN and SMOTE-Adaboost.

Published: March 2021

Despite the growing interest in mobile advertising targeting smartphones' users from a business perspective, academic research is still scarce regarding the implementation of mobile coupons and their redemption in retail stores, especially when integrating the location dimension. This study is addressing the needs for new insights about customers' attitudes, considering the technological and social evolution of the use of smartphones. This article explores how product and retail managers can offer mobile coupon opportunities to increase coupon redemption among potential customers using smartphones, and potentially concerned with privacy issues. Through the theory of planned behavior, this study finds that geolocation is a relevant variable in mobile advertising for a conversion rate optimization. The results suggest that geolocation has a positive impact on behavioral intention and increases the likelihood of coupon redemption.

Published: March 2021

The conversion of lignocellulosic biomass to biofuel as potential sources of transportation fuels, and for being both non-toxic and biodegradable. 5- Hydroxymethylfurfural (5-HMF) has been discovered to be a precursor for biofuel production and can be produced from biomass, which is readily available, renewable, and sustainable. Cellulose content in cassava peels is an opportunity to produce bio-based chemical products called 5-hydroxymethylfurfural. This study aims to determine the proper condition of glucose dehydration reaction of cassava peels hydrolysis. The optimum condition of dehydration reaction in this study was a glucose mass ratio: deep eutectic solvent of 1:6 and a reaction temperature of 80 ᵒC and the highest yield of 5-hydroxymethylfurfural using deep eutectic solvents (DES) based on choline chloride/oxalic acid was 70.22% and using DES based on choline chloride/oxalic acid was 64.50% at 5.70% glucose initial concentration using 1.5% H2SO4 catalyst on hydrolysis reaction cellulose of cassava peels. Physicochemical properties of deep eutectic solvents (DES) were pH of 5.8, density of 1.1574 gr/cm3 and viscosity of 119.33 cP. The results in this study indicate that the addition of DES choline chloride/oxalic acid can increase the yield of 5-hydroxymethylfurfural obtained.

Authors: Kumar Vikrant , Tayal Sachin , Ali Abbas , Gandhi Arun
Published: March 2021

Purpose of Study:

The purpose of the study was to evaluate the effect of patient characteristics and equipment-related factors on the computed tomography (CT) dose received by patients from positron emission tomography-CT (PET-CT) using system-generated dose-length product (DLP) values and also to check the effective dose (ED) received from various CT protocols at our institute.

Materials and Methods:

This retrospective study included 78 adult patients who underwent F-18 fluorodeoxyglucose whole-body PET-CT and were divided into three groups based on the area of primary cancerous lesion. In Group A, we had 44 patients who underwent PET-CT (head-and-neck protocol), in Group B, we had 24 patients who underwent PET-CT (whole body with brain protocol), and in Group C, we had 10 patients who underwent PET-CT (pelvis protocol). All of the patients under the study are of South Asian ethnicity. A majority of patients 53.85% were males and remaining 46.15% were females. The product of conversion factor (k-coefficient), as described in “American Association of Physicists in Medicine Report No. 96” and DLP value generated by the scanner, was used to calculate the ED. Moreover, we also performed regression analysis to check relation between body weight, height, scan range, tube current, Volume computed tomography dose index (CTDIvol), DLP, and ED.

Results:

The regression analysis shows that scan range, patient height, weight, tube current, and DLP were significantly correlated with ED (P < 0.05 for all). Moreover, the DLP and conversion factor method estimated the ED from various groups. Patients under Group A (head-and-neck protocol), Group B (whole body with brain protocol), Group C (pelvis protocol) received an average ED of 22.45 mSv, 22.40 mSv, and 21.24 mSv, respectively.

Conclusion:

ED from CT component of PET-CT can be assessed as the product of scanner-generated DLP and conversion factor for selected range. Moreover, body weight, scan range, and tube current had an independent significant effect on ED received from CT.

Published: March 2021

An elderly male on androgen deprivation therapy for prostatic adenocarcinoma presented with obstructive jaundice. Since biopsy from the head of the pancreas showed neuroendocrine carcinoma (NEC), he was diagnosed with second primary pancreatic NEC. Ga-68 DOTANOC positron emission tomography/computed tomography (PET/CT) done subsequently showed enlarged mildly DOTANOC-avid retroperitoneal nodes infiltrating the pancreas. These nodes were found to be progression of prostate-specific membrane antigen (PSMA) nonavid retroperitoneal nodes visualized in his Ga-68 PSMA PET/CT performed at another institution before 4 months, when there was no lesion in the pancreas. This observation revised the diagnosis from second primary pancreatic NEC to progression of neuroendocrine differentiation in preexisting prostatic adenocarcinoma.

Authors: Shiva R. , Ali Iqbal , Eswarawaka Mridula
Published: March 2021

Tuberculosis (TB) is considered as a ubiquitous disease, as it can involve any organ or a part of the body. Commonly, it involves the lungs and the abdomen. Muscle involvement is rare. In most cases, it is secondary to tubercular costochondritis or TB of the spine. Autopsy studies have revealed the abdominal wall involvement in <1% of patients who died of TB. A high index of suspicion is necessary to diagnose tubercular lesions in unusual anatomical locations. Antitubercular therapy is the main form of treatment; however, some patients may require surgical intervention. We are hereby presenting a case of tubercular anterior abdominal wall abscess secondary to wet peritonitis in a 40-year-old apparently healthy male with no past history of TB. The objective is to alert the clinicians and radiologists to the possibility of TB when considering such cystic lesions of the anterior abdominal wall.

Sampah merupakan permasalahan yang sering mucul di Kota manapun. Pada beberapa Negara Maju, sampah tidak lagi menjadi beban, namun sangat berpotensi dijadikan sebagai pembangkit listrik energi terbarukan. Dengan memanfaat gas metan yang dihasilkan, “sumber masalah” tersebut dapat terkelola sehingga tidak terbengkalai di TPA dan menimbulkan dampak negatif terhadap lingkungan sekitarnya. Bercermin dari hal tersebut, beberapa Kota besar di Indonesia meniru sistem pengolahan sampah menjadi listrik namun dengan metode yang beragam, termasuk Kota Singaraja. Bekerjasama dengan Kementrian ESDM, Pemda Singaraja mencoba membangun Pilot Project PLTG Landfill Bengkala, tepatnya di TPA Desa Bengkala, Kecamatan Kubutambahan. Akan tetapi, sampai saat ini project tersebut masih pada tahap penelitian dan beberapa waktu belakangan, belum dilanjutkan kembali. Dengan potensi TPA yang mampu menampung sampah hingga 165 ton, pengelolaan sampah berbasis sanitary landfill ini dapat menghasilkan listrik sebesar 2 MW. Apalagi dalam upaya pengembangan infrastruktur Pusat Kota Lama Singaraja, pemanfaatan gas metan dari sampah menjadi salah satu langkah inovatif, yang menjadikan kota tumbuh sebagai Kota yang mandiri karena dapat menghasilkan sumber energi listrik alternatif terbarukan. Tujuan penelitian ini adalah untuk memberikan usulan mengenai sumber energi listrik terbarukan yang murah dan ramah lingkungan.

No-Drama Obama: Personal Memoirs, Bestsellers, and Qualitative Research: A Review
Authors: Duffy Maureen
Published: March 2021

Personal memoirs and life histories are forms of qualitative research that from time to time appear on bestsellers lists. These forms of research detail the authors’ experiences of living and reflecting upon their everyday lives—lives that may be unique in some sense or lives made unique by the richness of the interplay of living, reflecting, and writing. In this review, I make the case for viewing moments in all lives as worthy of the development of personal memoir or life history and for using memoir as a way of generating takeaways or lessons learned. I review Elyn Saks’ (2007) memoir and bestseller about her life with schizophrenia, The Center Cannot Hold, and the British actor, author, and comedian, Stephen Fry’s 2006 documentary about bipolar disorder Stephen Fry: The Secret Life of the Manic Depressive. Both are examples of life histories that provide an abundance of opportunities for learning about what we might otherwise never know.

Authors: Smith Mark , Schmidt Karen
Published: March 2021

Using the theoretical framework of occupational socialization, the purpose of this study was to examine preservice physical education teachers’ beliefs and values of teachers and teaching through analysis and interpretation of favorite teacher narratives. One hundred and eighty six preservice physical education teachers’ narratives were collected and analyzed using open and axial coding (Corbin & Strauss, 2008). The qualities and characteristics identified through analysis were organized into seven inclusive sub-categories of favorite teacher characteristics and abilities and were articulated into three central themes, described as Pay it Forward, Caring in Teaching, and Motivated to Learn. The findings suggest that understanding favorite teacher influences on preservice teachers provides insights into maximizing the impact of physical education teacher education programs.
Building Connections: An Interpretative Phenomenological Analysis of Qualitative Research Students’ Learning Experiences
Authors: Cooper Robin , Fleisher Anne , Cotton Fatima
Published: March 2021

This paper describes a phenomenological study in which the authors explored students’ experiences learning qualitative research in a variety of academic fields. Semi-structured in-depth interviews were conducted with six participants from various academic fields who had completed at least one post-secondary-school-level qualitative research course and who were not students of the researchers. Using Interpretative Phenomenological Analysis (IPA), the researchers identified five primary themes representing the lived experience and meaning found in the participants’ experience of learning qualitative research: (a) a variety of feelings are experienced, (b) a pivotal experience serves as a catalyst in the learning process, (c) the central role of story, (d) active learning, and (e) relating learning to prior knowledge. The findings both support and contribute new aspects to the knowledge of this experience. The results also point to “building connections” as the essence of the phenomenon of learning qualitative research.
Thorough and Thought-provoking: A Review of Packer’s The Science of Qualitative Research
Authors: Parylo Oksana
Published: March 2021

The conflict between qualitative and quantitative directions in educational research is not new; however, this debate has resurfaced in the accountability era. The Science of Qualitative Research by Martin Packer (2011) is a thought-provoking book that explains why one should engage in qualitative research. Artfully combining history, examples, and his own reflections on the topic, Packer offers a list of well-grounded arguments that show the importance of and the need for qualitative research. Although this book does not explain how to design and conduct qualitative studies, it makes a good read for all those interested in theories behind modern qualitative work and for those who want to better understand the roots of scientific social research and common misconceptions about qualitative analysis.

Inferential statistics drawn include multiple regression and correlation analysis.

Findings: A significant majority (86.3%) of the respondents indicated that teachers advise on teenage pregnancy impacts positively on student behavior while the rest indicated that it impacted negatively

Unique Contribution to the Society, Policy and Theory: The findings of this research showed that socialization communication helps prevent teenage pregnancies. This therefore means that girls would be able to complete school advance in their studies and when they eventually are of age and ready for marriage, they can help alleviate vicious cycle of poverty as they are eligible to formal employment. There will be general growth in society as women will be empowered. The government and stakeholders should strengthen policies and enhance initiatives to educate more girls and reduce early marriages to the elders in the society, to socialize teenagers in the reality of modern life and the challenges that result in teenage pregnancies. The study improves the theory in that it connects socialization to the role of the teacher

Objectives. To determine the overall diagnostic yield of bronchoscopy-guided sampling methods in detecting lung cancer at the University of the Philippines, Philippine General Hospital. The diagnostic yield, equivalent to sensitivity, is defined as the number of bronchoscopic sampling or biopsy procedures with a diagnosis of malignancy divided by the total number of confirmed malignant cases.Methods. This is a cross-sectional, retrospective sensitivity study involving bronchoscopy procedures from January 2014 to December 2018. Surgical Pathology and Cytology Reports of eligible cases were accessed through the institutional Laboratory Information System. Sensitive patient information was omitted, and each case was assigned a unique code. The overall diagnostic yield/sensitivity of bronchoscopy and the diagnostic yield/sensitivity of each technique were calculated.Results. A total of 100 patients satisfied the inclusion and exclusion criteria. Primary lung malignancies are more common in males and the elderly. The most common primary lung cancer is adenocarcinoma (33%). Bronchoscopy, regardless of whether single or multiple techniques were used, has a diagnostic yield of 86% (CI: 77.6-92.1%). Of the individual techniques, those that obtain solid tissues (endobronchial and transbronchial biopsies; 88.2% [CI: 78.1-94.8%] and 80.0% [CI: 28.4-99.5%], respectively) have higher yields compared to techniques that obtain cytologic samples (bronchial washing and brushing; 54.2% [43.7-64.4%] and 70.1% [58.6-80%], respectively).Conclusion. Bronchoscopy, as a diagnostic procedure for pulmonary malignancies, has relatively high sensitivity and may be used for lesions located centrally and can be inspected visually. A multidisciplinary approach to patient selection for bronchoscopy helps improve the utility of the various bronchoscopic techniques.

Son on yılda yapılan kamuoyu yoklamaları, ilişkilerdeki gerilimle paralel olarak, Avrupa Birliği’ne (AB) desteğin sürekli azaldığını göstermektedir. Bir AB adayı ülke olarak Türkiye için AB’ye tam üyelik konusunda halkın desteğini almak gereklidir. AB’ye katılım müzakereleri kapsamında hazırlanan Türkiye’nin AB İletişim Stratejisi altında Türkiye kamuoyunun da üyeliğe hazırlanması gerekmektedir. Bu bağlamda, Türkiye kamuoyunun AB’ye verdiği desteğin ölçülmesi çok önemlidir. Bu araştırmanın temel amacı Kafkas Üniversitesi öğrencilerinin AB ve Türkiye-AB ilişkileriyle ilgili düşüncelerini ortaya koymak ve elde edilen bulguları önceki araştırmaların sonuçlarıyla karşılaştırmaktır. Araştırmanın evrenini Kafkas Üniversitesine kayıtlı 20.000 öğrenci oluşturmaktadır. 01.05.2019-07.01.2019 tarihleri arasında yapılan araştırma, Kafkas Üniversitesi’nin bütün fakülte ve yüksek okullarından 384 öğrenciye uygulanmıştır. Elde edilen veriler, SPSS 13 programı ile analize tabi tutulmuştur. Elde edilen veriler, önceki çalışmalarla karşılaştırılmış ve Kafkas Üniversitesi öğrencilerinin AB üyeliğini destek oranının çok düşük çıktığı görülmüştür.
Pancreatitis aguda. Artículo de revisión
Authors: Velázquez Gutiérrez Jesús , Vargas Useche Morella
Published: March 2021

Resumen: La pancreatitis aguda (PA) se define como un proceso inflamatorio agudo del páncreas el cual puede comprometer otros órganos y tejidos. El diagnóstico requiere al menos 2 de las siguientes características: dolor abdominal de moderada a fuerte intensidad, acompañado de náuseas y vómito; evidencia bioquímica de pancreatitis y/o evidencia por imágenes a través de tomografía axial computarizada dinámica (TACD) y/o la resonancia magnética (RM) del páncreas. Es la enfermedad gastrointestinal aguda más común que requiere ingreso hospitalario, siendo la evolución favorable en la mayoría de los casos (80%). Sin embargo, la pancreatitis necrotizante puede desarrollarse en hasta el 20% de los pacientes y se asocia con tasas significativas de insuficiencia orgánica temprana (38%). Los trastornos metabólicos y el ayuno comprometen el estado nutricional lo que podría agravar el curso de la enfermedad, por ello la vía de administración de la terapia nutricional ha demostrado tener un impacto en la evolución de los pacientes. Ahora existe una mejor definición de cuales pacientes con PA necesitan una terapia nutricional agresiva y cuales son aquellos que probablemente se beneficiarán de una nutrición enteral temprana.
Hernias poco comunes: hernia de Spiegel. Reporte de caso
Authors: Añolis Mariana , Reyes Andrés , Al Awad Adel , Matera María
Published: March 2021

La hernia de Spiegel es un defecto infrecuente de la pared abdominal producido por una alteración en la unión del borde lateral del músculo recto del abdomen y el borde medial del músculo transverso del abdomen en la línea semilunar. Representan apenas del 0,12 al 2% de todas las hernias. La presente investigación se enfocó en describir las manifestaciones clínicas, el diagnóstico, la incidencia, el procedimiento quirúrgico y su evolución en dos casos reportados. Caso 1: Femenina de 33 años, multípara, obesa, quien consulta por dolor y masa palpable en el cuadrante superior izquierdo del abdomen. Al examen físico, se evidenció dolor a la palpación en mesogastrio e hipocondrio izquierdo, exhibiendo protrusión del contenido abdominal, en la línea de Spiegel. Intervención quirúrgica: hernioplastia protésica de Spiegel con colocación de malla supraaponeurótica. Caso 2: Masculino de 89 años, con diagnóstico de enfermedad pulmonar obstructiva crónica, acudió a consulta presentando dolor abdominal en fosa iliaca y en la región inguino–escrotal izquierda. Al examen físico se evidenció saco herniario en la región inguino–escrotal por lo que se decide su resolución quirúrgica. Como hallazgo transoperatorio se evidenció defecto aponeurótico del recto anterior del abdomen izquierdo en su tercio inferior. Intervención quirúrgica: hernioplastia protésica de Spiegel con colocación de malla supraaponeurótica. Conclusión: La hernia de Spiegel es una entidad poco frecuente por lo que se debe concientizar al cirujano para sospechar este tipo de hernia en aquellos pacientes con presencia de aumento de volumen en la línea de Spiegel.

Latinos nos EUA - Unindo Américas, fazendo a América de lá ou perdendo a nossa América?
Authors: Castro Mary Garcia
Published: March 2021

A para os Estados Unidos não é um fenômeno novo, registrando-se deslocamentos de mexicanos para os estados norte-americanos fronteiriços ao México, por exemplo, Califórnia, Texas, Arizona e Novo México, ou seja, para terras que originalmente eram do México, desde meados do século 19. Também é anterior à II* Guerra Mundial o deslocamento para os EUA de massiva corrente de europeus e mais tarde de asiáticos. Na história daquele país os membros dessa corrente são chamados “pioneiros” ou os “velhos imigrantes”. O crescimento dos novos imigrantes, em particular de origem asiática e latina, é ilustrado no Quadro 1. Note-se que em 1960 cerca de 10% dos imigrantes ‘ilegais’eram de origem asiática e 25% da América Latina, enquanto em 1985 os asiáticos passam a representar <juase a metade do contingente de imigrantes documentados, e os provenientes da América Latina, um terço.

O rural-urbano e a escola brasileira

Published: March 2021

Para compreender como vejo a questão da educação rural (e urbana) na sociedade brasileira hoje, é preciso, logo no início deste artigo, superar a razão dualista que costuma dicotomizar os fenômenos humanos, contrapondo-os em pares antagônicos: cultura x natureza, rural x urbano, países desenvolvidos x países subdesenvolvidos, etc. Tal maneira conceituai de organizar o raciocínio pode ajudar a compreender os fenômenos a partir da ciência positivística, mas é obscurecedora do real em sua complexidade (totalidade).

Tempos e Espaços
Authors: Magnani José Guilherme Cantor
Published: March 2021

Este número da Revista Travessia, dedicado ao tema " Tempo e Espaço", à primeira vista podería parecer um mero exercício especulativo, desvinculado da dura realidade da vida dos migrantes. Trabalhadores do campo e da cidade, teriam lá eles, em sua luta do dia-a-dia pela sobrevivência, disposição, ânimo e condições para preocupar-se com conceitos parentemente tão abstratos? Pois não só teriam, como realmente o fazem. E à sua maneira, como mostram os diferentes artigos deste número da revista. Seja no contexto das grandes metrópoles ou de cidades médias, de povoados litorâneos ou de cidades de fronteira - o que se vê é uma produção constante e diversificada de maneiras de ver, usufruir e dar significado a realidades que erroneamente se supõe serem iguais para todos: o tempo e o espaço.

E no início dos anos oitenta que surgem os principais questionamentos contrários ao entendimento do “setor informal” como setor “marginal” , “ autônomo” , de “ fácil entrada” etc., como foi concebido na discussão dos anos setenta (1). É também nesse período que surge no Brasil um interesse maior por parte de pesquisadores das regiões mais desenvolvidas do país pelo tema, antes estudado apenas como um “problema do Nordeste”, principalmente em cidades como Salvador e Recife.
