Authors: Gil López Eugenio 
Published: May 2019

El presente artículo trata de analizar la aplicación de la denominada Teoría del Conocimiento Efectivo a la hora de determinar la responsabilidad de los Prestadores de Servicios de Intermediación (ISP), centrado fundamentalmente en dos tipos de prestadores: aquellos que prestan un servicio de alojamiento o almacenamiento de contenidos, y los que prestan un servicio de búsqueda y enlace a contenidos ajenos. Partiendo del hecho de que la actividad de estos prestadores es un instrumento clave para el desarrollo y la evolución de Internet, debe determinarse que ocurre en el supuesto de que los contenidos alojados o los enlaces realizados lesionen bienes y/o derechos de terceros, para lo cual se procede a analizar la normativa aplicable a este tipo de prestadores, la interpretación y aplicación realizada de la misma por los tribunales españoles y de la Unión Europea en casos concretos, y ya anticipa postura contraria a esta interpretación en determinados supuestos que considera incompatible con las reglas exigibles en el ámbito de la seguridad jurídica.Palabras Clave: ISP, Conocimiento Efectivo, instrumentos de búsqueda. This article attempts to analyze the application of the so-called theory of knowledge Effective on determining the liability of Intermediary Service Providers (ISP), focusing mainly on two types of providers, on the one hand those who provide a service storage or hosting content, and on the other those who provide a service search and link to external contents. Given the fact that the activity of these providers is a key to the development and evolution of Internet tool, we must determine what happens in the event that hosted content or links made injure goods and / or rights, for which is to analyze the rules applicable to such providers, interpretation and application made of it by the Spanish courts and within the scope of the European Union in specific cases, and we anticipate our stand against this interpretation in certain cases we consider incompatible with enforceable rules in the field of legal certainty.Keywords: ISP, Effective Knowledge, search tools.

CRISIS DE LA EPISTEMOLOGÍA DE LAS CIENCIAS SOCIALES Y LA EDUCACIÓN COMPARADA
Authors: Escudero Jaime Caiceo 
Published: May 2019

Este artículo persigue preguntarse por qué las ciencias sociales en general, y la educación comparada en particular, no han tenido el desarrollo esperado. La razón de lo anterior se encuentra en que cuando surge la ciencia moderna lo hace en torno a los problemas propios de la física (ciencia pura), la astronomía (ciencia aplicada) y la matemática (ciencia instrumental) en que se estudia el mundo natural, el cual tiene siempre un comportamiento uniforme. Copérnico, Bacon, Galileo, Kepler y Newton entre los siglos XVI y XVII así lo entendieron y lo estudiaron, desarrollando la epistemología propia de las ciencias naturales. Dilthey nos indica en Introducción a las Ciencias del Espíritu (1883) que las ciencias sociales no han tenido el desarrollo esperado porque han utilizado el modelo epistemológico propio de las ciencias naturales; por ello, propone buscar una epistemología propia para las ciencias sociales, pues el objeto de estudio son los hombres y sus relaciones, que no tienen un comportamiento uniforme. A pesar de todos los esfuerzos realizados durante el siglo pasado aún no se logra. Por lo mismo, la Educación Comparada no ha tenido el desarrollo esperado. La metodología utilizada es la propia de la filosofía -analítico-reflexiva-, considerando a sus autores en sus fuentes.Palabras Claves: Epistemología/ Ciencias Naturales/ Ciencias Sociales/ Dilthey/ Educación Comparada.

A pesquisa apresentada tem como objeto de estudo a análise da importância do profissional pedagogo no processo de recuperação e reinserção social dos usuários de drogas na cidade de Uberaba, Estado de Minas Gerais. Ela foi possível, graças ao Conselho Municipal de Políticas Públicas sobre Drogas. Utilizando-se de um levantamento documental, bibliográfico e de outros recursos de cunho normativo, foi focado o contexto de atuação do pedagogo, alargando-o ainda mais com as políticas públicas, com a reinserção social e com outras interfaces. O objetivo geral da pesquisa foi ressaltar o valor da função pedagógica na reinserção social dos usuários de drogas no munícipio, levando em consideração as Diretrizes Curriculares Nacionais para o Curso de Graduação em Pedagogia, licenciatura (CNE/CP nº 1/2006), também para as sinergias de efeito ativo e retrocessos, em que se inserem os espaços não escolares para o debate. Esses diversos aspectos emergiram de reformas efetuadas, visando os cuidados de seus destinatários, em outros níveis de observações, que a investigação, por associações imprevisíveis, terminou por produzir. Na análise final dos dados, verificaram-se inconsistências no papel desempenhado pelo pedagogo na tarefa de reinserção do usuário de drogas. Por fim, as recomendações da Declaração de Caracas, as quais foram adotadas pela Organização Mundial de Saúde, assim como os conceitos produzidos pelo Terceiro Setor foram fundamentais para a análise das ações governamentais.

Writing English text is basic competence that students must be common to write because writing plays an important role to enable the students to describe their ideas in logical and in a communicative way. The objectives of this research were to find out whether or not there was a significant correlation between learning motivation together with writing anxiety and writing achievement. The method used was descriptive method and the design was in the form of correlational research. By using total sample, 97 students of SMA ETHIKA Palembang were chosen as the sample of this research. Two questioners and writing test were administered to collect the data. The research results show that (a) there was a positive significant correlation between learning motivation and writing achievement (r=0.845), (b) there was no significant correlation between writing anxiety and writing achievement (r=-0.053), (c) the multiple correlation analysis of all independent variables showed a positive and significant correlation (r= 0.845). Regression analysis showed that learning motivation influenced or contributed partially 84.5% to writing achievement and writing anxiety partially contributed 5,3%, the combination of learning motivation together with writing anxiety contributed 71.5% to writing achievement.
Biomechanical implications of unilateral facetectomy, unilateral facetectomy plus partial contralateral facetectomy, and complete bilateral facetectomy in minimally invasive transforaminal interbody fusion

Published: May 2019

OBJECTIVEMinimally invasive transforaminal interbody fusion techniques vary among surgeons. One decision point is whether to perform a unilateral facetectomy (UF), a unilateral facetectomy plus partial contralateral facetectomy (UF/PF), or a complete bilateral facetectomy (CBF). The authors therefore compared the biomechanical benefits of all 3 types of facetectomies to determine which approach produces improved biomechanical outcomes.METHODSSeven human cadaveric specimens (L3–S1) were potted and prepped for UF, with full facet removal, hemilaminectomy, discectomy, and pedicle screw placement. After distraction, a fixed interbody spacer was placed, and compression was performed. A final fixation configuration was performed by locking the rods across the screws posteriorly with bilateral compression. Final lordosis angle and change and foraminal height were measured, and standard nondestructive flexibility tests were performed to assess intervertebral range of motion (ROM) and compressive stiffness. The same procedure was followed for UF/PF and CBF in all 7 specimens.RESULTSAll 3 conditions demonstrated similar ROM and compressive stiffness. No statistically significant differences occurred with distraction, but CBF demonstrated significantly greater change than UF in mean foraminal height after bilateral posterior compression (1.90 ± 0.62 vs 1.00 ± 0.45 mm, respectively, p = 0.04). With compression, the CBF demonstrated significantly greater mean ROM than the UF (2.82° ± 0.83° vs 2.170° ± 1.10°, p = 0.007). The final lordosis angle was greatest with CBF (3.74° ± 0.70°) and lowest with UF (2.68° ± 1.28°). This finding was statistically significant across all 3 conditions (p ≤ 0.04).CONCLUSIONSAlthough UF/PF and CBF may require slightly more time and effort and incur more risk than UF, the potential improvement in sagittal balance may be worthwhile for select patients.
Tensor decomposition and non-local means based spectral CT image denoising
Authors: Zhang Yanbo , Salehjahromi Morteza , Yu Hengyong 
Published: May 2019

BACKGROUND As one type of the state-of-the-art detectors, photon counting detectors are used in spectral computed tomography (CT) to classify the received photons into several energy channels and generate multichannel projections simultaneously. However, FBP reconstructed images contain severe noise due to the low photon counts in each energy channel. OBJECTIVE A spectral CT image denoising method based on tensor-decomposition and non-local means (TDNLM) is proposed. METHODS In a CT image, it is widely accepted that there exists self-similarity over the spatial domain. In addition, because a multichannel CT image is obtained from the same object at different energies, images among different channels are highly correlated. Motivated by these two characteristics of the spectral CT images, tensor decomposition and non-local means are employed to recover fine structures in spectral CT images. Moreover, images in all energy channels are added together to form a high signal-to-noise ratio image, which is applied to encourage the signal preservation of the TDNLM. The combination of TD, NLM and the guidance of a high-quality image enhances the low-dose spectral CT, and a parameter selection strategy is designed to achieve the optimal image quality. RESULTS The effectiveness of the developed algorithm is validated on both numerical simulations and realistic preclinical applications. The root mean square error (RMSE) and the structural similarity (SSIM) are used to quantitatively assess the image quality. The proposed method successfully restored high-quality images (average RMSE=0.0217 cm-1 and SSIM=0.987) from noisy spectral CT images (average RMSE=0.225 cm-1 and SSIM=0.633). In addition, RMSE of each decomposed material component is also remarkably reduced. Compared to the state-of-the-art iterative spectral CT reconstruction algorithms, the proposed method achieves comparable performance with dramatically reduced computational cost, resulting in a speedup of >50. CONCLUSIONS The outstanding denoising performance, the high computational efficiency and the adaptive parameter selection strategy make the proposed method practical for spectral CT applications.

Published: May 2019

Research aim : This study aimed to get empirical evidence of the effect of tax rates and the adoption of IFRS to Foreign Direct Investment (FDI). The study also attempts to identify whether a country needs to adopt IFRS fully, convergence IFRS or not using IFRS able to increase FDI. Otherwise to detect Tax rates from Asean Economic Community Countries can affected FDI. Design / Methodology / Approach: This study uses a quantitative descriptive approach. The sample consisted of 54 observations of each variable that consists of information 9 countries of the ASEAN Economic Community (AEC) during the years 2011 to 2016. The proposed model was tested using multiple regression analysis through partial t test, as well as simultaneous test F. Research findings: The results showed the tax rate in a country negatively affect FDI and the adoption of IFRS by a country has a positive effect on FDI, while simultaneously tax rates and the adoption of IFRS have a significant effect on FDI. Contributions theoretical / Originality : This study extends the theoretical concept of tax rates and the level of IFRS adoption, even though previous research has been done before in developing countries, and there is no research that focuses on AEC countries. Previous research used a simple score of 2 to 3 score levels in AECsuring the level of IFRS adoption in each sample country so that it was not able to accurately AECsure the level of IFRS adoption in each country. This Research is using five (5) levels of scores taken from the IASB namely full adoption, adapted, pieceAECl, referenced, and not adoption at all. Practicioner / Policy Implication: The result will be useful to policy makers as an authoritative Tax and Accounting Bodies in AEC Countries as an input to identify factors which can increase Foreign Direct Investment. Research Limitation/Implication : This Study used data from 2011 to 2016, however, others factors could be used with FDI in future researches.

Published: May 2019

Aim: To assess whether serum Vitamin D levels are associated with general and abdominal obesity in young adults.
Materials & Methods: A total of 113 MBBS students of the same batch aged 17–21 years (59 boys and 54 girls) were included in this case-control study. Height and body weight were measured to calculate Body Mass Index (BMI) for General obesity and waist circumference was measured for central obesity. Plasma vitamin D levels were measured. Participants were grouped according to Asian criteria for BMI and abdominal circumference in normal and obese group.
Results: Mean age of students, who participated in study, was 18.2± 0.95 years. In the general obesity group the mean plasma Vitamin D level was 18.77±13.31ng/ml and in its normal reference group(with normal BMI) the mean plasma Vitamin D level was 19.02±16.21ng/ml. In the central obesity group the mean plasma Vitamin D level for males was 21.10±13.30ng/ml and in females 13.52±10.5 ng/ml and in its normal reference group(with normal waist circumference) the mean plasma Vitamin D level in males was 20.16±11.89ng/ml and in females it was 12.66±9.40 ng/ml.
Conclusion: Comparison between obese group and normal group revealed that general obesity and central obesity has no correlation with plasma Vitamin D levels. Plasma Vitamin D deficiency was prevalent even in apparently healthy young individuals and it is more common in females.
