Effective ICT use for Digital Innovation: An Actualized Affordance Perspective through ICT enabled Design Thinking
Authors: Shirish Anuragini , Srivastava Shirish C. , Boughzala Imed
Published: July 2021

Les technologies de l’information (TIC) disponibles dans les organisations peuvent être utilisées pour créer des solutions innovantes d’une manière rapide, efficace et économique. Malgré la nécessité de mieux comprendre les modalités permettant d’utiliser les TIC dans les organisations pour favoriser l’innovation, la littérature sur l’innovation numérique/digitale se concentre principalement sur l’étude de la mise en œuvre de TIC existantes dans de nouveaux contextes ou sur la conception et le développement de nouvelles technologies de l’information. Cet article enrichit ces travaux de recherche en étudiant un mécanisme créatif alternatif mobilisant les technologies digitales existantes pour l’innovation. En ancrant nos arguments dans la littérature sur l’usage efficace des SI et « l’affordance de la technologie », nous conceptualisons les caractéristiques des agents d’innovation et l’affordance actualisée de l’innovation basée sur l’utilisation des TIC, comme les deux principaux facilitateurs de l’innovation digitale. Les caractéristiques des agents d’innovation sont opérationnalisées par le biais de caractéristiques génériques et spécifiques au domaine de « l’auto-efficacité créative » et de « l’affect envers l’utilisation des TIC ». L’affordance de l’innovation actualisée est opérationnalisée comme l’utilisation efficace des technologies disponibles grâce à une approche de conception basée sur les TIC ou encore « ICT enabled design-thinking » (ICT-DT). Le modèle proposé est testé empiriquement via une méthode quasi-expérimentale comprenant des données provenant d’une enquête en deux temps de collecte. Les résultats montrent une influence significative à la fois des caractéristiques de l’agent d’innovation et de l’affordance actualisée de l’innovation pour faciliter l’innovation digitale. Cependant, l’affordance actualisée de l’innovation, opérationnalisée par l’approche ICT-DT, a une relation plus forte avec l’innovation digitale par rapport aux caractéristiques de l’agent d’innovation. Cela souligne la nécessité pour les organisations d’intégrer l’utilisation des TIC pour permettre des approches de créativité structurées (telles que le DT) et encourager les productions innovantes. L’étude offre également plusieurs implications pour la recherche et pour la pratique.
How protection motivation and social bond factors influence information security behavior
Authors: Berthevas Jean-François
Published: July 2021

Les technologies numériques sont omniprésentes, avec pour corollaire la prolifération des attaques contre les actifs informationnels. Ainsi, la sécurité de l’information (IS) semble être une question cruciale pour les individus et les gestionnaires. Si les tentatives d’identification des facteurs qui guident le comportement des acteurs en matière de sécurité de l’information (ISB) ne sont pas nouvelles, cette identification reste plus nécessaire et actuelle que jamais. De ce point de vue, cette étude empirique contribue à une meilleure compréhension des facteurs cognitifs et de socialisation qui influencent les comportements en matière de sécurité de l’information. En utilisant un modèle hiérarchique de second ordre avec modélisation partielle par équations structurelles des moindres carrés (PLS-SEM), nous testons pour la première fois l’applicabilité de la théorie de la motivation de protection (PMT) et de la théorie du lien social (SBT) à la sensibilisation aux technologies de la sécurité de l’information (ISTA) et au comportement de protection contre les logiciels malveillants (MPB) de 430 étudiants. Premièrement, nos résultats démontrent que la combinaison de la PMT et de la SBT produit un modèle plus robuste pour l’analyse de l’ISTA et de la MPB que si l’on considère chacune de ces théories séparément. Deuxièmement, l’ISTA agit en partie comme médiateur des liens sociaux et de la motivation de protection et pourrait donc être un comportement de sécurité fondamental. Si nous soulignons le rôle prépondérant de l’implication, la différence significative observée dans les ISB des deux sexes est liée à la plus forte influence pour les femmes, des liens sociaux sur l’ISTA. Ce résultat s’explique notamment par des effets plus homogènes des facteurs de socialisation chez les femmes que chez les hommes. Nous suggérons que la conception des programmes et de l’enseignement de l’ISTA soit mieux adaptée aux différents facteurs cognitifs et de socialisation des individus, notamment en mettant l’accent sur les liens sociaux et, plus spécifiquement, sur l’implication. Nous fournissons également des recommandations détaillées sur la manière dont les praticiens peuvent améliorer les ISB des individus.
Anaerobic enrichment of Bacillus alkylbenzene remedial consortia from waste biomass melanoid sources

Bioremediation of alkylbenzenes, including toluene, ethylbenzene and xylenes, was performed using fermentable aromatic sources and electron mediators by Bacillus cereus 301 in a limited oxygen state. The fermentation of small fermentable aromatic melanoids from cow manure as soluble humus hydrolysates or sugarcane molasses as saccharine, glucose and limited basal medium was compared. Thus, an evaluation model of exponential decline against a control was incorporated for interpretation of remedial data. The significance of the present strategy for constructing multivariant effects of electron donors could be objectively judged by pattern comparison with the short-term data analyzed. Thus, grafted aromatics as methyl- or ethylbenzene require much more microbial reaction time, even with mixed aromatic donors or stronger electron donors such as methanol in the original reduced medium, as indicated in the scatter chart. However, completion of the remedial time was needed by the kinetic simulation, and even low, smooth data were expressed. Among the exponential decay curves indicated, the carbon sources in the mix were favorably expressed. The smooth pattern indicated that fermentations with glucose and molasses showed lower remedial activity than melanoids or the indole series. The vigor increase was better for melanoid carbon in the initial fermentation of 24 h, while molasses increased later at 72 h and was more quenched by amending indole acetic acid (IAA) or indole expression. The molecular interaction of the electron mediator indole acetic acid in most trials indicated a quenched effect on toluene and ethylbenzene degradation, even when mixed with the original reducing medium, but expressed better with molasses in both kinetic simulations and growth effects. Thus, combining electron mediators such as IAA for Bacillus may offer a new degradation route for the metabolite alkylbenzene, which is worth further exploration for environmental aromatic waste remediation and combined restoration strategies.
Hamilton type gradient estimates for a general type of nonlinear parabolic equations on Riemannian manifolds
Authors: Zeng Fanqi ,   School of Mathematics and Statistics, Xinyang Normal University, Xinyang, 464000, China
Published: July 2021

In this paper, we prove Hamilton type gradient estimates for positive solutions to a general type of nonlinear parabolic equation concerning $ V $-Laplacian:

   \begin{document}$ (\Delta_{V}-q(x, t)-\partial_{t})u(x, t) = A(u(x, t)) $\end{document}

on complete Riemannian manifold (with fixed metric). When $ V = 0 $ and the metric evolves under the geometric flow, we also derive some Hamilton type gradient estimates. Finally, as applications, we obtain some Liouville type theorems of some specific parabolic equations.

Authors: Alhaleem Nour Abed ,   Department of Mathematical Sciences, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, Bangi 43600, Selangor, Malaysia, Ahmad Abd Ghafur
Published: July 2021

Motivated by the new notion of intuitionistic fuzzy normed ideal, we present and investigate some associated properties of intuitionistic fuzzy normed ideals. We describe the intrinsic product of any two intuitionistic fuzzy normed subsets and show that the intrinsic product of intuitionistic fuzzy normed ideals is a subset of the intersection of these ideals. We specify the notions of intuitionistic fuzzy normed prime ideal and intuitionistic fuzzy normed maximal ideal, we present the conditions under which a given intuitionistic fuzzy normed ideal is considered to be an intuitionistic fuzzy normed prime (maximal) ideal. In addition, the relation between the intuitionistic characteristic function and prime and maximal ideals is generalized. Finally, we characterize relevant properties of intuitionistic fuzzy normed prime ideals and intuitionistic fuzzy normed maximal ideals.

Authors: KIM Yujong , MOON Myungkook , LEE Jae-Sang
Published: July 2021

In 2012, the Korea Multi-purpose Accelerator Complex (KOMAC) facility with a total construction budget of about $300M was constructed at Gyeongju in Korea. It has a 75 m long 100 MeV proton accelerator, which can supply the highest average beam current of 1.6 mA. Since 2013, the KOMAC has been operating the 100 MeV proton accelerator for the official user beam service with two multi-purpose beamlines, one at 20 MeV and the other at 100 MeV. In 2015, the first new high-flux beamline was constructed for a medical isotope production, and the second new beamline was added in 2016 to provide a low-flux proton beam irradiation service mainly for research on the effects of radiation on semiconductors, spacecraft parts, and medical/biological samples. By the help of recent increased usages of Korean semiconductor manufacturing companies, such as SAMSUNG and SK hynix, the competition rate for requesting beam time of the proton accelerator was increased as high as 3.54:1 in 2020. To support various research fields with good user satisfaction, we have been preparing to increase the beam energy of the proton accelerator from 100 MeV to at least 500 MeV. In this article, we describe the construction history, current operational status, and various applications of the KOMAC proton accelerator and its future upgrade plan.

In this paper, we present recent progress in the PAL-XFEL, including the present status of its operation. The increase in the FEL pulse energy is explained, and the generation of a self-seeding FEL is described. In addition, the generation of a two-color FEL is mentioned.
Mercenarios y clases dependientes en el imperio espartano: un capítulo de historia social
Authors: Fornis César
Published: July 2021

Esparta fue el primer Estado griego en hacer un uso masivo de mercenarios extranjeros. Al mismo tiempo, a nivel interno recurre al servicio militar de los hilotas, que alcanzarán la libertad pero no la ciudadanía. Ambos desarrollos se relacionan con el esfuerzo militar continuo exigido por el proyecto de construcción imperial espartano. Por otro lado, muchos lacedemonios que no pertenecían a la clase dominante de los homoioi pero que, sin embargo, habían sido adiestrados en el uso de armas, abandonaron Esparta para trabajar como soldados de fortuna aprovechando las posibilidades que la influencia del imperio ofrecía en varias regiones de importancia geoestratégica, lo cual suponía una especie de válvula de escape que aliviara la tensión sociopolítica en Laconia. De esta forma, mercenarios espartanos y mercenarios al servicio de Esparta son dos procesos imbricados y que corren en paralelo durante la vigencia del imperio espartano, desde la guerra del Peloponeso hasta la batalla de Leuctra.

Authors: Romeo Marugán Francisco
Published: July 2021

El análisis de la cartografía y fotografías históricas ha permitido identificar una estructura de grandes dimensiones en el entorno inmediato de la ciudad antigua del Cabezo de Alcalá de Azaila que, hasta el momento, había pasado desapercibida. La utilización de tecnologías avanzadas de teledetección aérea, junto con la prospección de campo y la prospección magnética, ha conseguido reconocer un complejo escenario bélico del I a. C. en el que destaca un gran recinto de planta cuadrada y un sistema de agger y fosos que rodean la acrópolis de la ciudad. Este trabajo presenta una primera aproximación a los resultados obtenidos en 2017, que abren una serie de posibilidades sobre las que hay que profundizar.
Dos nuevas hachas de época tardoantigua procedentes de los fondos del Museo de Guadalajara (siglos V-VI). Cronología y contexto cronocultural
Authors: Catalán Ramos Raúl , Daza Pardo Enrique , Vega Rivas Elena
Published: July 2021

Este trabajo presenta dos hachas de hierro tardoantiguas inéditas depositadas en el Museo de Guadalajara que proceden de sendos hallazgos fortuitos realizados en el norte de la provincia. Ambos casos se adscriben a tipologías poco comunes en Hispania, ya que los paralelos más claros se encuentran fuera del ámbito peninsular. Dada su extremada rareza, su documentación y análisis proporciona tanto la ampliación del repertorio de elementos vinculados con el mundo militar tardorromano y altomedieval en el centro peninsular, como la movilidad y dispersión de tipos por toda Europa.
¿Quién protege a los soldados? Representación colectiva y práctica de la protección en los ejércitos españoles de la edad moderna
Authors: Recio Morales Óscar
Published: July 2021

La precaria situación de oficiales y soldados en los ejércitos españoles de la Edad Moderna, unida a los problemas de meritocracia y venalidad, causaron la desafección dentro de la profesión y su desprestigio fuera de ella. Este estudio plantea el problema de la representación colectiva de la gente de guerra y las soluciones propuestas desde la administración. Nos centramos en dos de las múltiples respuestas posibles: la figura institucionalizada del «protector del soldado» de los Habsburgos y la práctica de la protección desarrollada por los inspectores de los Borbones. Las conclusiones avanzan que el «protector del soldado» fue una respuesta vacía de contenido y de poco calado; los inspectores, por su parte, se enfrentaron a una dura oposición en su práctica de la protección y en sus intentos de extensión de su jurisdicción sobre todos los cuerpos del ejército. Los límites a la representación colectiva —la reivindicada desde las tropas, por una parte, y la ofrecida desde las instituciones, por otra— nos permiten avanzar en una lectura política de la protección asistencial y la falta de recursos para cubrir las necesidades y expectativas de los militares.

Authors: Hu Jin Lian , Jiang Yuan Zhang , Gu Lin
Published: July 2021

Spiders silks have extraordinary strength and toughness simultaneously, thus has become dreamed materials by scientists and industries. Although there have been tremendous attempts to prepare fibers from genetically manufacture spider silk proteins, however, it has been still a huge challenge because of tedious procedure and high cost. Here, a facile spider-silk-mimicking strategy is reported for preparing highly scratchable polymers and supertough fibers from chemical synthesis route. Polymer films with high extensibility (>1200%) and supertough fibers (~387 MJ m-3) are achieved by introducing polypeptides with β-sheet and α-helical structure in polyureathane/urea polymers. Notabley,the toughness of the fiber is more than twice the reported value of a normal spider dragline silk, and comparable with the toughest spider silk, aciniform silk of Argiope trifasciata.
Thermal Camouflage Clothing in Diurnal and Nocturnal Environments
Authors: Pimenta Catarina , Morais Carla , Fangueiro Raul
Published: July 2021

This paper shows the possibility to thermally camouflage a human body in a beach environment, during the day and at night, through the use of two knitted fabric clothing prototypes. The conceptual design process applied was initially developed based on the need to firstly understand the behaviour of an individual dressed under the focus of a thermal imaging camera in the light of the infrared spectrum. The thermal tests undertaken to observe the model's thermal camouflage in certain positions/perspectives in both environments, enable simultaneously running of different solutions while introducing changes to the clothing. Printing with copper pigments and the patchwork using stitched structures in polyester knitted fabric played a decisive role to capture the thermal colours of the thermal image intended for the camouflage effect.
Mechanical Design and Manufacturing of Signal Interception Antenna in Composite Material for Naval Application
Authors: Santoro Daniele , Lecci Umberto , Pera Fabio Massimo , Gaetano Domenico , Bia Pietro , Manna Antonio
Published: July 2021

This work shows the mechanical design and the FE analyses performed for an innovative naval Antenna Unit for signal interception application: more than twenty electromagnetic sensors operating from HF up to Ka band and microwave modules are integrated in a unique structure designed for a top mast installation (i.e. for naval platform). The number of constraints in terms of weight and electromagnetic transparency calls for the employment of composite materials such as glass, aramidic and carbon epoxy prepregs. Primary structures was modelled by using FE codes: both orthotropic and isotropic models have been implemented as well as non-linear contacts and bolted joints. The mast-mounted installation requires high mechanical stiffness and strength but the exposure to saline environment needs many manufacturing issues to be respected. In particular, the selection process of suitable materials and the sealing manufacturing procedures to protect them from the external agents was reported. Another key feature of the presented design concerns the electromagnetic compatibility requirement: to avoid electromagnetic emissions (EMC) generated by antenna’s internal units and to protect antenna sensors by external platform’s emitters, an appropriate stacking sequence was chosen for composite laminates with a prepreg copper mesh.

Authors: Jawad Yaqoob M. , Al-Kadhemy Mahasin F. Hadi , Salman Jehan Abdul Sattar
Published: July 2021

Nanocomposites were prepared by the method of solution casting with different proportions of magnesium oxide nanoparticles (0, 1, 3, 5, 7 and 9) wt%. The structural and optical properties of nanocomposites of CMC/MgO have been studied. It was well known that the increased content of MgONPs in the method contributes to the peaks of MgONPs being completely integrated and/or disappearing within the CMC diffraction halos in the experimental results of XRD study. The differences in the XRD spectrum indicate that doping with nanoparticles induced a disparity in the microstructure of the polymer. Nanocomposite film scanning electron microscopy (SEM) reveals that MgONPs appear to form aggregates and scatter well in (CMC/MgO) nanocomposite films and at apply 9 wt. It forms a continuous network within the polymer for the percentage of MgONPs to (CMC) polymer. FTIR spectrum revealed the MgONPs has no destructive influence on the polymer structure as no covalent bonds formed between CMC and MgONPs. The optical properties of CMC/MgO nanocomposites were measured in wavelength range (200–900) nm. Experimental studies have shown that the absorbance, absorption coefficient, extinction coefficient, refractive index, actual and imaginary dielectric constant of CMC polymer is improved with an increase in concentrations of MgONPs in nanocomposites. The transmittance and energy gap of CMC polymer are decreased with the increase in the concentrations of MgONPs.

Pulmonary function, computerized tomography features and six-minute walk test at three months in severe COVID-19 patients treated with intravenous pulsed methylprednisolone: a preliminary report
Authors: Van Zeller Cristiano , Anwar Asad , Ramos-Bascon Nordita , Barnes Natalie , Madden Brendan
Published: July 2021

COVID-19 ARDS has a high mortality and few therapeutic options. We present a preliminary report on our experience using high-dose pulsed methylprednisolone in COVID-19 ARDS and three-month outcomes. We performed a retrospective analysis of all patients treated with high-dose methylprednisolone for COVID-19 ARDS and three-month lung function, 6MWT, and CT findings. 15 patients were treated of which 10 survived to discharge. Reduced DLCO was the commonest abnormality in lung function tests and had the lowest mean value. Parenchymal bands were the commonest CT finding and 50% of patients had fibrosis at three-months. Mean 6MWD was 65.4% predicted and was abnormal in 62.5% of patients. In this cohort of patients with COVID-19 ARDS treated with high-dose methylprednisolone pulses, CT, lung function, and 6MWT abnormalities were unsurprisingly common at three months, although all 10 patients treated early in their disease course survived, a possible therapeutic effect. Further randomised controlled trials are needed to assess the benefits of this treatment.

Published: July 2021

Objective:

To determine the healthcare utilization patterns and estimate the economic burden of animal bites in Golestan province, north part of Iran.

Methods:

This cross-sectional study was performed based on the data of 12 181 animal-bite patients from Golestan province who were referred to the rabies prophylaxis centers between March 2019 and March 2020. The study was a societal perspective, and all patients were investigated by census method. The micro-costing method with a bottom-up approach as well as the human capital approach were used to estimate the economic burden.

Results:

In our study, the economic burden caused by animal bites was estimated at $1 383 639 (275 354 672 060 Rials). The largest share of costs was related to direct healthcare costs, direct non-healthcare costs, and indirect costs accouting for 91%, 5%, and 4%, respectively. In addition, the average cost of a animal-bite patient was estimated at $113.5 (22 605 260 Rials) (The average cost of a case in type 2 and 3 exposures was $45 and $412.8, respectively). The largest share of direct healthcare costs was related to immunoglobulin, vaccine, and personnel expenses accounting for 61.3%, 19.8%, and 11.65%, respectively.

Conclusions:

Our study shows that animal bites in Golestan province, north of Iran impose a high economic burden on the communities, especially the healthcare system, which indicates the need to review management and control programs of animal bites and rabies based on animal-bite patterns of the area.
Pulmonary neuroendocrine carcinoid tumors
Authors: Patané Ana Karina , Guma Gabriela , Rayá Mercedes , Rosales Adolfo , Astorino Walter , Rosenberg Moisés
Published: July 2021

INTRODUCTION:

There are several factors predicting evolution in carcinoid tumors (CT) to date including the Ki67 role.

AIMS:

The aim of this study is to identify a KI67 cut-off point for a population of CT and determine its prognostic implication in global and disease-free survival.

METHODS:

Hematoxylin-eosin slides of 102 CT were revised. The percentage of cells expressing Ki 67 was determined manually.

STATISTICAL ANALYSIS:

The variables were compared with the t-test or the Wilcoxon test according to their distribution, the categorical ones with Chi-square or Fisher's test. The best cut-off point was established by constructing receiver operating characteristic curves, then using that value as a dichotomous variable.

RESULTS:

72 typical carcinoids (TC) and 30 atypical carcinoids (AC) were analyzed; 66% were female. Median age (TC 38 vs. AC 51, P = 0.001), Ki67 expression (TC 0.63 vs. AC 2, P = 0.003), tumor size (TC 2.5 vs. AC 2.6, P = 0.001), the percentage relapse (TC 3.4% vs. AC 23%, P = 0.006), and the number of deaths (TC 1 vs. AC 4, P = 0.042) were significantly higher in the AC subgroup. The best cut-off point for Ki 67 was 0.755 (area under the curve AUC 0.564, 95% confidence interval 0.270–0.857), with no significant differences found in the disease-free and overall survival curves when considering values < or ≥ at the established cut-off point. The best cut-off point of the Ki-67 when exclusively analyzing AC was 1.18. When using this value as a predictive variable, a marginal statistical association was observed between Ki-67 expression, mortality (P = 0.077), and the frequency of relapses (P = 0.054).

CONCLUSIONS:

Histological type is the best predictor of prognosis in the carcinoid tumor group. In the AC subgroup, the marginal association between mortality, frequency of relapses and Ki values 67 ≥ 1.18 has clinical relevance future analyses are required to determine the real predictive value of this variable.

Introduction:

Coronavirus disease 2019 (COVID-19) pandemic has affected the physical and rehabilitation medicine (PRM) specialty globally. The effects of this pandemic on PRM residents in 14 countries of the Americas are described in this study.

Materials and Methods:

This study is based on the international survey done by the World Youth Forum of the International Society of Physical and Rehabilitation Medicine. The cross-sectional data obtained were analyzed for a point-of-view study (August 2020).

Results:

PRM residents reported multiple challenges in their training program including mental health issues during the pandemic. In all the countries, there was either complete or partial closure of services provided by PRM specialists at the height of the crisis. In some areas, there was a necessity to temporarily transform the rehabilitation service into a COVID-19 unit and to assign residents to medical and intensive care units. Residency programs in 13 countries introduced virtual lectures and examinations. The duration of residency will probably increase in three countries, may not be affected in another six, and is still undetermined in five. The specialty licensing examination was temporally suspended/postponed in four countries, administered in a modified way in one, and has not been affected yet in four.

Conclusion:

COVID-19 pandemic adversely affected the training of PRM residents in the Americas. Despite the efforts to overcome this, the residents need more support including well-being programs. Every country and training program should continue to evolve to adapt to the crisis and anticipate additional challenges in the near future.

Authors: Rana Sakshi , Khosla Divya , Periasamy Kannan , Kapoor Rakesh
Published: July 2021

Malignant peripheral nerve sheath tumor (MPNST) is a soft-tissue sarcoma arising from or differentiating toward peripheral nerve sheath cells. It accounts for 5%–10% of soft-tissue sarcomas. The most common sites of origin are proximal portion of upper, lower limbs and trunk. MPNST arising from the nerve plexus of gastrointestinal tract is extremely rare, and only very few cases have been reported in literature. In this report, we are describing a case of MPNST from mesocolon. An 82-year-old male presented to hospital with complaint of pain abdomen and feeling of lump on the left side of lower abdomen for the past 2 months. On contrast-enhanced computed tomography (CECT) of chest and abdomen, there was 15 cm × 10 cm mass palpable in left lumbar region without ascites and multiple random subpleural nodules in bilateral lung. Intraoperatively, there was 15 cm × 10 cm hard irregular mass in left paracolic gutter infiltrating mesentry of descending colon. Left hemicolectomy was performed with end-to-end anastomosis. Histopathological examination revealed malignant peripheral nerve sheath tumor, and on immunohistochemistry, tumor cells were positive for S-100 and negative for C-kit and Smooth Muscle Actin (SMA). The patient was started on tamoxifen in view of old age and lung metastasis. The patient is on follow-up from 2 years with stable disease. In this report, we highlight the possibility of clinical differential diagnosis of MPNST arising from mesocolon should be kept while dealing with mesenchymal tumors of colon. Radical surgery with negative margins is required for achieving palliation, and adjuvant tamoxifen could offer advantage in patient who cannot tolerate chemotherapy.

PurposeDue to low incidence, epidemiologic data of Ewing sarcoma in the Asian population are scarce. We aimed to examine the incidence pattern and outcome of patients with Ewing sarcoma in the Republic of Korea.Materials and MethodsData of patients with Ewing sarcoma diagnosed between 1999 and 2017 were obtained from the Korea Central Cancer Registry (KCCR). Incidence, clinical characteristics, and survival rates were analyzed and compared between different age groups. ResultsThere were 788 cases (459 males, 329 females), with a median age at diagnosis of 20 years. The age-standardized rate of Ewing sarcoma was 1.01. The number of cases and incidence rates in each age group were as follows: children, 1.6; adolescents and young adults (AYA), 0.93; adults, 0.44; and elderly, 0.53. There were more male cases in children and the AYA group (p < 0.001). Extraskeletal tumors (p < 0.001), primary sites other than extremity (p=0.007), and presence of metastasis at diagnosis (p=0.031) were more frequent in the adults and elderly group. With a median survival time of 78 months, the 5-year overall survival (OS) rate of the entire cohort was 52%. Children fared best (5-year OS, 75%), and the 5-year OS of AYA patients (51%) approximated the OS of the entire cohort. A two-fold difference of 5-year OS was observed between adults and elderly patients (42% vs. 19%). On univariate and multivariate analyses, age ≥ 15 years and presence of metastasis were adverse prognostic factors.ConclusionThis was the first epidemiologic study of Ewing sarcoma using the KCCR data. With a similar incidence to other Asian countries, the survival rate was slightly lower than that of Euro-American cases. Collaborative clinical studies are necessary to improve the outcome of Ewing sarcoma in low-incidence populations.
Moč maske v literaturi
Authors: Samide Irena
Published: July 2021

V navezavi na trenutno pandemijo članek preučuje motiv maske v književnosti ter njegov vpliv na posameznikovo samopodobo in identiteto. Pri obravnavi vprašanja, kakšne funkcije ima maska v literarnih delih, kakšen je njen učinek in kakšno moč ima, članek najprej pregledno oriše novoveško evropsko in zlasti nemško književnost, nato pa se podrobneje posveti simbolnim razsežnostim maske v obdobju dunajske moderne, ki je z raziskavami na področju medicine, nevrologije, psihologije in psihoanalize prinesla tudi nova spoznanja o jazu. Z motivno-tematsko analizo Sanjske novele Arthurja Schnitzlerja članek prepoznava ambivalentno vlogo maske v človekovem odkrivanju identitete, z analizo Rilkejevega romana Zapiski Malteja Lauridsa Briggeja pa vlogo obrazne maske kot simbolnega sprožilca razkroja identitete, se pravi njeno vlogo v reprezentaciji procesa od samozavedanja do samorazkroja.
Ukrainian Theatrical Drawings and Sketches of the Avant-Garde Era
Authors: Maystrenko-Vakulenko Yuliya
Published: July 2021

The study of time, space and movement as constituent art elements was a focus of attention of avant-garde artists. The theatre where events unfold both in space and time became a place of consolidation of Ukrainian artists, with the synergistic association of representatives in various art branches and movements. A scenographic sketch, that is, a two-dimensional realisation of idea of a future four-dimensional work, is a unique phenomenon to study the evolution of the avant-garde’s concept of the space-time continuum. Through the example of works of both distinguished and less known Ukrainian theatre artists we have studied features of the realisation of time and space categories according to the key stylistic directions of the Ukrainian avant-garde: cubism, futurism, cubo-futurism, constructivism, suprematism. A theoretical basis for the study has been provided by works of Western thinkers of the late nineteenth and early twentieth centuries: Edmund Husserl, Henri Bergson, Oswald Spengler, Ludwig Wittgenstein, Maurice Merleau-Ponty, and Meyer Schapiro, along with the Ukrainian art theorists Kasimir Malevich, Aleksandr Bogomasov, and Les Kurbas, as well as works of modern researchers such as Linda Henderson and Igor Duchan.
We have drawn a parallel between the development of art concepts in the Ukrainian avant-garde and scientific achievements, and the sense of time and space categories in the philosophical thought of that epoch.
Kratka kulturna biografija grafitov in likovne ulične umetnosti ter razlikovanje med njima na podlagi teorije družbenega življenja stvari
Authors: Konda Helena
Published: July 2021

Prispevek metodološko izhaja iz socialne zgodovine umetnosti. Uvodoma je predstavljena tipologija grafitov in likovne ulične umetnosti s poudarkom na dihotomiji jezikovnega in likovnega načina uličnega izražanja. Pri dosedanjem pojasnjevanju razlike med grafiti in likovno ulično umetnostjo je v strokovnih in drugih krogih pretežno uporabljena deskriptivna metoda. Splošno razumevanje je, da je druga oblika vizualna nadgradnja prve, pri razčlenjevanju po fizičnih lastnostih, vsebini in obliki pa je veliko prekrivanja, ker sta morfološka sloga obeh podobna. Prispevek interpretativno pojasnjuje razliko med njima, in sicer z vpletenostjo v družbena razmerja, na podlagi tradicionalnega razlikovanja dveh tipov menjave – darovanja in trgovine. Analiza izhaja iz teorije družbenega življenja stvari Arjuna Appaduraija. Različne razvojne stopnje grafitov so klasificirane po kategorijah različnih vrst blaga in strnjene v kratko kulturno biografijo po modelu Igorja Kopytoffa.
Družbeni strahovi med znanostjo in kulturnim bojem
Authors: Vidmar Horvat Ksenija
Published: July 2021

Članek analizira porast teorij zarot v obdobju pandemije COVID-19. Glavnina študij, ki se v zadnjem času posvečajo tematiki teorij zarote, izpostavlja dva ključna dejavnika, ki prispevata k njihovemu razširjanju in privlačnosti: družbena omrežja in z njimi povezan razmah alternativnih resnic ter naraščanje nezaupanja do znanosti. Oba dejavnika lahko prispevata k razumevanju sodobne »epistemološke krize«, ne moreta pa v celoti pojasniti splošnejšega »protirazsvetljenskega obrata« v družbeni zavesti. Avtorica v tem prispevku k tematiki pristopa s primerjavo vzpona teorij zarot in razmaha skrajnega populizma. Primerjalna analiza struktur občutenja pri obeh, trdi, omogoča prepoznavanje vloge neoliberalne države, ki je sprožila vrsto socialnih strahov in, vzporedno, na mestu skupnega dobrega odprla prostor za polariziranje skupnosti.

Published: July 2021

Preeclampsia is a major cause of maternal and fetal morbidity and mortality. Early recognition of the disease may be challenging. Complications may precede the onset of clinical symptoms and medical intervention is often delayed. Moreover, in the absence of specific clinical signs, many patients will present symptoms mimicking the disease without ever being diagnosed with preeclampsia. This situation may, however, lead to medical interventions and cause unnecessary stress for the patient. For many years, research tried to evaluate the significance of serum biomarkers as early indicators of preeclampsia. Among many, the sFlt-1/PlGF ratio, given its performance, aroused the greatest interest. This article reviews current knowledge on the subject, focusing on a Swiss perspective.

Queer Shakespeare; Focus on Henry IV (Part I & II)
Authors: Sarkar Dipak Kumar
Published: July 2021

Shakespeare has undoubtedly shown his mastery in the depiction of the characters in his world celebrated dramas. Despite, being among the bests, Shakespeare has not been able to disregard homosexuality and its presentation in the characters’ activities. The objective of this paper is to find out how queer Shakespeare and his characters have been in Henry IV plays. Moreover, the queer approach of Shakespeare as a writer and person is the aim to be found out in this paper. For this investigation, a queer analysis of the texts along with critics’ view, historical review, theories like feminism, psychoanalysis and queer are to be applied here to find out Shakespeare’s attitude towards sexuality for the better understanding of the works of Shakespeare in general.

EDUCAÇÃO SEXUAL EM LIVROS DIDÁTICOS DE CIÊNCIAS: ABORDAGENS CULTURAIS E SILENCIAMENTOS
Authors: MACHADO LUISA , LÚCIA ESCOVEDO SELLES SANDRA
Published: July 2021

O PRESENTE ARTIGO INVESTIGA, ATRAVÉS DA ANÁLISE DE LIVROS DIDÁTICOS, COMO OS CURRÍCULOS DE CIÊNCIAS ABORDAM A TEMÁTICA DE EDUCAÇÃO SEXUAL. PARA ISSO, ANALISAMOS SETE LIVROS DIDÁTICOS DE CIÊNCIAS DO 8º DO ENSINO FUNDAMENTAL, TENDO COMO REFERENCIAL TEÓRICO-METODOLÓGICO QUATRO ABORDAGENS DO ENSINO DO CORPO HUMANO PROPOSTAS NA LITERATURA: BIOMÉDICA E FISIOLÓGICA; COMPORTAMENTAL; SOCIOAMBIENTAL; E CULTURAL. AO LONGO DA ANÁLISE IDENTIFICAMOS QUE AS CONCEPÇÕES BIOMÉDICA E COMPORTAMENTAL ESTÃO PRESENTES EM TODOS OS LIVROS, TENDO COMO BASE AS CIÊNCIAS DE REFERÊNCIA. POR OUTRO LADO, AS OUTRAS DUAS CONCEPÇÕES APARECEM APENAS NOS LIVROS MAIS RECENTES, SUGERINDO MAIOR APROXIMAÇÃO COM AS QUESTÕES SOCIAIS QUE ENVOLVEM A TEMÁTICA. SENDO ASSIM, ARGUMENTAMOS QUE A EDUCAÇÃO SEXUAL CONSTITUI UMA DAS TRADIÇÕES CURRICULARES DO ENSINO DE CIÊNCIAS, MAS ATUALMENTE É COLOCADA EM XEQUE DIANTE DO CONSERVADORISMO NO BRASIL, AMEAÇANDO ASSIM O CURRÍCULO DE CIÊNCIAS E A EDUCAÇÃO DEMOCRÁTICA.
