Análisis de la Responsabilidad Social y Sostenibilidad en Gestión Universitaria. Caso: Universidad técnica particular de Loja-Ecuador. Social Analysis of responsibility and sustainability in university management. Case Universidad Técnica particular ...
Authors: Ortiz Criollo José Fernando 
Published: July 2017

En las últimas décadas el concepto de “Responsabilidad Social” y “Sostenibilidad” ha ganado espacio en el ámbito organizacional; en el sentido de fijar en las empresas la concepción de ser socialmente responsables por sus actos, en los ámbitos ético, social, económico y medio ambiental. Si bien es cierto este proceso de cambio ha tenido buenos resultados todavía se espera un largo camino para consolidar a las organizaciones dentro de los principios y parámetros de lo social y sosteniblemente responsable.
Bajo este sentido, no debemos pasar por alto el hecho de que las universidades no dejan de relacionarse con el concepto de Responsabilidad Social; pues son unidades complejas que tienen como fin el formar profesionales con alto nivel de conocimiento y, que este conocimiento adquirido sea transformado en resultados que coadyuven al desarrollo de las condiciones de vida de la sociedad.
El objetivo de este artículo es hacer una interpretación de algunos aspectos de la gestión de la Universidad Técnica Particular de Loja y en base a ello generar un análisis crítico de su modelo de responsabilidad social universitaria; el cual vincula las funciones sustantivas con sus grupos de interés, identificados éstos como autoridades, funcionarios, docentes, empleados, estudiantes y la sociedad en general.

OBJECTIVEReports on supratentorial extraventricular ependymoma (STE) are relatively rare. The object of this study was to analyze the clinical, radiological, and histological features and treatment outcomes of 14 patients with STE.METHODSOverall, 227 patients with ependymoma underwent surgical treatment in the authors’ department between January 2010 and June 2015; 14 of these patients had STE. Data on clinical presentation, radiological studies, histopathological findings, surgical strategies, and treatment outcomes in these 14 cases were retrospectively analyzed.RESULTSThe patients consisted of 6 women and 8 men (sex ratio 0.75). Mean age at diagnosis was 24.5 ± 13.5 years (range 3–48 years). Tumors were predominantly located in the frontal and temporal lobes (5 and 4 cases, respectively). Typical radiological features were mild to moderate heterogeneous tumor enhancements on contrast-enhanced MRI. Other radiological features included well-circumscribed, “popcorn” enhancement and no distinct adjoining brain edema. Gross-total resection was achieved in 12 patients, while subtotal removal was performed in 2. Radiotherapy was administered in 7 patients after surgery. Seven tumors were classified as WHO Grade II and the other 7 were verified as WHO Grade III. The mean follow-up period was 22.6 months (range 8–39 months). There were 3 patients with recurrence, and 2 of these patients died.CONCLUSIONSSupratentorial extraventricular ependymoma has atypical clinical presentations, various radiological features, and heterogeneous histological forms; therefore, definitive diagnosis can be difficult. Anaplastic STE shows malignant biological behavior, a higher recurrence rate, and a relatively poor prognosis. Gross-total resection with or without postoperative radiotherapy is currently the optimal treatment for STE.
H i Kinematics and Mass Distribution of Messier 33
Authors: Kam S. Z. , Carignan C. , Chemin L. , Foster T. , Elson E. , Jarrett T. H. 
Published: July 2017

Abstract
A new deep H i survey of the galaxy Messier 33 is presented, based on observations obtained at the Dominion Radio Astrophysical Observatory. We observe a perturbed outer gas distribution and kinematics in M33, and confirm the disk warping as a significant twist of the major axis of the velocity field, although no strong tilt is measured, in agreement with previous work. Evidence for a new low-brightness H i component with anomalous velocity is reported. It harbors a large velocity scatter, as its kinematics both exceeds and lags the rotation of the disk, and leaks in the forbidden velocity zone of apparent counterrotation. The observations also reveal wide and multiple-peak H i profiles that can be partly explained by crowded orbits in the framework of the warp model. Asymmetric motions are identified in the velocity field as possible signatures of a lopsided potential and the warp. The mass distribution modeling of the hybrid Hα–H i rotation curve favors a cuspy dark matter halo with a concentration in disagreement with the ΛCDM dark halo mass–concentration relationship. The total mass enclosed in 23 kpc is

, of which 11% are stars and gas. At the virial radius of the cuspy halo, the resulting total mass is

, but with a baryonic mass fraction of only 2%. This strongly suggests a more realistic radius encompassing the total mass of M33 that is well smaller than the virial radius of the halo, possibly comparable to the size of the H i disk.
Revisiting SNR Puppis A with Seven Years of Fermi Large Area Telescope Observations

Published: July 2017

Abstract
Puppis A is a very famous and extensively studied supernova remnant that shows strong evidence of shock-cloud interaction. We reanalyze its GeV γ-ray emission using seven years of Pass 8 data recorded by the Fermi Large Area Telescope. The morphology of the γ-ray emission is more compatible with that of the thermal X-ray and IR emissions than the radio image, which suggests a possible correlation between the gamma-ray-emitting region and dense clouds. The γ-ray spectrum in the energy range of 1–500 GeV shows a break at 7.92 ± 1.91 GeV, with photon indices of 1.81 ± 0.08 below the break and 2.53 ± 0.12 above the break, which can naturally explain the lack of TeV γ-ray emission from Puppis A. The multi-wavelength observations favor a hadronic origin for the γ-ray emission.
Refractive Changes Induced by Spherical Aberration in Laser Correction Procedures: An Adaptive Optics Study
Authors: Amigó Alfredo , Martinez-Sorribes Paula , Recuerda Margarita 
Published: July 2017

PURPOSE:
To study the effect on vision of induced negative and positive spherical aberration within the range of laser vision correction procedures.

METHODS:

In 10 eyes (mean age: 35.8 years) under cyclopegic conditions, spherical aberration values from −0.75 to +0.75
µ
m in 0.25-
µ
m steps were induced by an adaptive optics system. Astigmatism and spherical refraction were corrected, whereas the other natural aberrations remained untouched. Visual acuity, depth of focus defined as the interval of vision for which the target was still perceived acceptable, contrast sensitivity, and change in spherical refraction associated with the variation in pupil diameter from 6 to 2.5 mm were measured.

RESULTS:

A refractive change of 1.60 D/
µ
m of induced spherical aberration was obtained. Emmetropic eyes became myopic when positive spherical aberration was induced and hyperopic when negative spherical aberration was induced (
R
2
= 81%). There were weak correlations between spherical aberration and visual acuity or depth of focus (
R
2
= 2% and 3%, respectively). Contrast sensitivity worsened with the increment of spherical aberration (
R
2
= 59%). When pupil size decreased, emmetropic eyes became hyperopic when preexisting spherical aberration was positive and myopic when spherical aberration was negative, with an average refractive change of 0.60 D/
µ
m of spherical aberration (
R
2
= 54%).

CONCLUSIONS:
An inverse linear correlation exists between the refractive state of the eye and spherical aberration induced within the range of laser vision correction. Small values of spherical aberration do not worsen visual acuity or depth of focus, but positive spherical aberration may induce night myopia. In addition, the changes in spherical refraction when the pupil constricts may worsen near vision when positive spherical aberration is induced or improve it when spherical aberration is negative.

Authors: Prabhu P. Rajesh , Jain Mayank , Bawane Piyush , Varghese Joy , Venkataraman Jayanthi 
Published: July 2017

ABSTRACT
Background: The interface between tuberculosis (TB) and Crohn’s disease (CD) is relevant as TB complicates both the diagnosis and management of CD. Aim: This study aimed to identify the distinctive characteristics of ileocaecal and colonic TB (C‑TB) and colonic CD (C‑CD) at colonoscopy and to correlate the colonoscopy findings with histology. Materials and Methods: This prospective study included consecutive patients presenting with classical symptoms of TB or CD. The colonoscopic findings were compared with histology, which was taken as gold standard. Appropriate statistical tests were applied. Results: Fifty‑eight individuals fulfilled the inclusion criteria. Nine and 16 patients with C‑TB and C‑CD, respectively, had histological confirmation of respective diagnosis. In 33 specimens, the histological diagnosis was inconclusive. The sensitivity of colonoscopy for diagnosing C‑TB was high at 88.9% (95% confidence interval [CI]: 51.8–99.7). It was 50% (95% CI: 24.7–75.4) for CD. The reverse was true for CD whose specificity was high at 71.4% (95% CI: 55.3–84.3) and low for TB at 46.9% (95% CI: 32.5–61.7). All the patients diagnosed as confirmed CD or TB responded well to respective treatment. Six of the thirty patients with failed response to anti‑TB treatment required surgery or change in treatment after 2 months. Conclusion: Colonoscopic findings of isolated ileal involvement, aphthous ulcer, cobble stoning, long‑segment strictures, skip lesions and perianal involvement favored a diagnosis of CD. Correlation of colonoscopy with histology is poor for both CD and TB. The accuracy, sensitivity and specificity of colonoscopy were better and superior for the diagnosis of CD, than in the diagnosis of TB.

ABSTRACTSchistosomiasis is prevalent in tropical and subtropical areas. It manifests as an acute or chronic illness caused by the body’s reaction to the worms’ eggs. In view of its clinical similarity to various other diseases, the disorder may cause diagnostic errors. We present a case of a Sudanese man, who presented with fever, headache, fatigue, myalgia, excessive sweating, abdominal cramps, and a high eosinophil count on blood testing. He was diagnosed with a connective tissue disorder and was started on prednisolone, but 3 weeks later, he presented with rectal bleeding. Colonoscopy showed features of moderate distal colitis. Colonic biopsies revealed several viable schistosome ova associated with aggregates of eosinophils, compatible with active colonic schistosomiasis.

ABSTRACTPseudoaneurysm is a known complication of pancreatitis associated with significant morbidity and mortality. Computed tomography (CT) localizes the pseudoaneurysm apart from the severity of underlying pancreatitis. Digital subtraction angiography with coil embolization is recommended treatment for pseudoaneurysm to avoid bleeding and surgery. However, in cases where angiographic coil embolization fails due to technical reasons, CT/ultrasonography‑ guided thrombin injection remains a viable option as described in literature. In the present case, role of endoscopic ultrasound‑guided thrombin injection into large pseudoaneurysm that was not feasible by angiographic occlusion has been highlighted. The procedure avoided surgery and its related complication.

ABSTRACTVideo capsule endoscopy is now the first-line tool in evaluating and diagnosing obscure gastrointestinal bleeding, inflammatory bowel disease, and small bowel neoplasms. Capsule retention is an uncommon but clinically significant complication. How to best retrieve these retained capsules is currently being debated. In this case report, we describe a retained capsule successfully retrieved using double-balloon enteroscopy. This case also highlights the fact that capsule retention can occur even in the absence of signs and symptoms suggestive of intestinal obstruction.

En Física, un gran número de magnitudes son vectores, y su uso requiere operaciones típicas tales como: suma, resta, multiplicación por un escalar, producto escalar, producto vectorial y producto mixto. Se trata de conceptos básicos en todos los cursos de Física General para grados en Ingeniería. Sin embargo, algunos estudiantes carecen de una comprensión profunda de las operaciones vectoriales y sus propiedades.En este trabajo presentamos un laboratorio virtual (desarrollado utilizando la herramienta “Easy Java Simulations”) para el estudio y comprensión de estos conceptos. El usuario puede introducir las componentes de los vectores de entrada y obtiene una representación 3D, que puede escalar y girar para una mejor visualización. Se puede seleccionar cualquiera de las operaciones antes mencionadas, y se muestra el resultado tanto numérica como gráfica-mente. El usuario puede también modificar cualquiera de los vectores repre-sentados. De esta forma, el laboratorio virtual proporciona una visualiza-ción en tiempo real de cómo el cambio afecta al resultado. También se incluye la posibilidad de modificar únicamente el módulo o la orientación.Para comprobar la eficiencia del laboratorio virtual, se han analizado los resultados obtenidos por dos grupos de estudiantes (laboratorio virtual vs. recursos tradicionales). También se ha realizado una encuesta de opinión.Palabras clave: laboratorio virtual, Física, Easy Java, análisis vectorial.
