With the social media era considering as a turning point for communication age sharing has become unlimited. Many families have being chosen technological devices rather than a safe play area for their children. It has been considered that children is hang by a thread regarding easily accessibility and personal info via YouTube which is considered the biggest video sharing platform and another recent micro-film applications which is popular with under 18 years old children.
It is necessary that children and adolescents to get connect with their peers. The children and adolescents who are lurking in online world without any guidance may join social media movements so called “trends”.
The other thread which children and adolescents could face is the video-sharing sites which turned into trading sector. While children are online, their parents who have an urge to get goods from those sites give their children a chief part in those videos.
In some videos, children are forced to behave unnatural regarding unmatched behaviors to their mental and physical development by their parents. Another negativity for children who have a role in these videos is destructive comments that are typed under videos. Some comments which are filled with jealousy and anger can be labeled as “cyber-bullying”
Consequently, when the severe usage of YouTube and video-sharing sites because of widespread use of Internet is considered, it has been a necessity to protect children’ personal information and their privacy. The harm which is stemmed from sales policy has to be spoken by...
Kannabis Yasal, Ya Sonra…

Published: April 2020

Recently, it is seen that the regulations regarding the use of psychoactive substances such as cannabis are considered just as a public security problem in specific periods and it is expected to be controlled by legal precautions. However, with the realization that the problem of substance use and addiction is not a mere public security problem, treatment and prevention activities have started to be given importance. In recent years, it has been observed that people who both regulate medical treatment, and work on the legal framework and related to the psychosocial dimension of the incident, have been working sensitively on legal regulations and new developments. From now on the substance use is evaluated within “public health and society safety”, and along with this, especially cannabis regulations are being changed rapidly and the issue is still being discussed in many countries. It is thought that it will be difficult to predict the long-term consequences of these practices as the basis of both individual and societal in terms of public health and public safety. This article is written in order to summarize the individual and social consequences that may arise if the use of recreational cannabis is allowed by compiling the studies regarding the subject.

Combined Porogen Leaching and Emulsion Templating to produce Bone Tissue Engineering Scaffolds
Authors: Owen Robert , Sherborne Colin , Evans Richard , C. Reilly Gwendolen , Claeyssens Frederik
Published: April 2020

Bone has a hierarchy of porosity that is often overlooked when creating tissue engineering scaffolds where pore sizes are typically confined to a single order of magnitude. High internal phase emulsion (HIPE) templating produces polymerized HIPEs (polyHIPEs): highly interconnected porous polymers which have two length scales of porosity covering the 1–100 µm range. However, additional larger scales of porosity cannot be introduced in the standard emulsion formulation. Researchers have previously overcome this by additively manufacturing emulsions; fabricating highly microporous struts into complex macroporous geometries. This is time consuming and expensive; therefore, here we assessed the feasibility of combining porogen leaching with emulsion templating to introduce additional macroporosity. Alginate beads between 275 and 780 µm were incorporated into the emulsion at 0, 50, and 100 wt%. Once polymerized, alginate was dissolved leaving highly porous polyHIPE scaffolds with added macroporosity. The compressive modulus of the scaffolds decreased as alginate porogen content increased. Cellular performance was assessed using MLO-A5 post-osteoblasts. Seeding efficiency was significantly higher and mineralized matrix deposition was more uniformly deposited throughout porogen leached scaffolds compared to plain polyHIPEs. Deep cell infiltration only occurred in porogen leached scaffolds as detected by histology and lightsheet microscopy. This study reveals a quick, low cost and simple method of producing multiscale porosity scaffolds for tissue engineering.
Managing natural disaster risk with earthquake damage scenarios and shakeout exercises: Lessons from Mw = 8 Mandi multi-stakeholders scenario in India
Authors: Taneja Pawan Kumar , Taneja Shallini
Published: April 2020

Scientifically simulated Earthquake Damage Scenario (EDS) and Shakeout exercises help the policymakers to set up emergency plans for the immediate consequences and medium-long-term mitigation and prevention for a seismic event. The purpose of this study is to draw important lessons and a deeper understanding of issues and challenges in planning and implementing such exercises in a highly populous developing country like India. The Government of India developed a first-ever multi-state and multi-stakeholders EDS naming Mw = 8 Mandi and conducted a Mega Multicity Shakeout Exercise in the Western Himalayan Region during 2014. A cross-sectional research design consisting of a mainly qualitative research approach using a multi-stakeholders perspective approach was used to factor key lessons. The scenario development and shakeout exercise faced several challenges such as lack of awareness among concerned stakeholders, lack of technical know-how at the grass-root level, lack of poor coordination among various stakeholders, and unavailability of data on important issues. Due to the lack of understanding of the sensitivity of the issue, the success of implementation largely depends on the involvement of the top leadership of state governments. Scientific EDS exercises followed by mega shakeout exercises helped not only the community up to some extent but also mainly helped administration, government agencies in generating awareness of the earthquake and possible risk attached to it.
Multiscreening and Social TV
Authors: Marinelli Alberto , Andò Romana
Published: April 2020

The explosive growth of handheld screen devices has fostered the emergence of new TV consumption practices: “always connected while watching TV” is the expression that best summarizes this transformation. On the one hand, we observe multiscreening practices engendered by the availability of second screen devices, which people use both simultaneously and sequentially while watching. On the other hand, these handheld devices are strengthening the social dimension of the TV-watching experience (Social TV). This paper aims to analyze the diffusion of social and connected television in the Italian market, relying on data from the “Osservatorio Social TV 2013-2014” (Sapienza University, Rome).
Newspaper Video Content
Authors: Negredo Samuel
Published: April 2020

Newspaper websites and online only news operations deliver an increasingly varied and comprehensive offer of original audiovisual content. In Spain, they cover current affairs and niche interests, complementing the video reports supplied by news agencies. The spoken word is a primary mode of expression, in the form of dialogues (interviews and debates) and speeches (comments and analyses), but more complex and visually appealing formats have been developed. There is a challenge to organise these packages and programmes in order to facilitate access and retrieval, which may help to improve user experience, and to maximise long-term consumption and value.
Wide-Screen Television and Home Movies
Authors: Steward Tom James Longley
Published: April 2020

In this article, Tom Steward uses past interrelations of television and cinema spectatorship, exhibition, production and aesthetics to historicize phenomenological digital-era discourses on, ontological definitions of, and cultural arguments about television and cinema convergence. He argues that television and cinema assisted in defining each other as late 20th Century media and cultural forms, have a multi-directional industrial and artistic flow, and are often interdependent in reception and distribution. Television and cinema convergence demonstrates the need for historical breadth in media convergence theory and an understanding of medium-specificity that incorporates interactions with other media.
‘The Schneiderverse’
Authors: Dare-Edwards Helena Louise
Published: April 2020

This article will analyse the textual features of two recent and successful American-based Nickelodeon shows, both of which incorporate digital and social technologies into their sitcom-style format. Aimed at a tween-girl1 audience, these ‘convergence comedies’2 complicate traditional notions of media spectatorship and the distinctions between media producers and consumers as audiences are invited to participate in the processes of production. While media convergence is built into the visual style of both shows, the shows themselves converge to create a shared fictional world, dubbed the ‘Schneiderverse,’ which traverses the boundary between the real and the fictional. It will be considered how the audience’s media experience3 could be enriched through immersion in the online spaces associated with the texts.
Editorial
Authors: Fickers Andreas , Weber Anne-Katrin
Published: April 2020

Over the last few years, ‘media archaeology’ has evolved from a marginal topic to an academic approach en vogue. Under its banner, conferences and publications bring together scholars from different disciplines who, revisiting the canon of media history and theory, emphasize the necessity for renewed historiographical narratives. Despite, or maybe because of profuse debates, media archaeology remains a loosely defined playground for researchers working at the intersection of history and theory. Far from offering uniform principles or constituting a homogeneous field, its prominent authors – Friedrich Kittler and Wolfgang Ernst, Siegfried Zielinksi, Jussi Parrika and Erkki Huhtamo, to name just a few – distinguish themselves by their heterogeneity regarding methodology and theoretical focus.

OPTIMIZATION OF GAS TURBINE POWER PLANT BY EVOLOUTIONARY ALGORITHM; CONSIDERING EXERGY, ECONOMIC AND ENVIRONMENTAL ASPECTS
Authors: SHAMOUSHAKİ Moein , ALİEHYAEİ Mehdi
Published: April 2020

In this paper the exergy, economic and environmental analysis of Aliabad Katoul power plant as well as its multiobjective
optimization have been done by NSGA-II algorithm. Two objective functions have been considered. The first
objective function is the total cost rate and the second objective function is environmental impact cost. Optimization of
objective functions has been done in two modes namely cycle with and without air preheater. The results showed that the
existence of air preheater reduces both objective functions. So that in optimum point, for cycle without air preheater, the
amount of total cost rate has been about 30% and environmental cost rate was about 33% higher than cycle with air
preheater. Also, sensitive analysis of objective functions to fuel unit cost was conducted. At the lower environmental cost
rate that the total cost rate was higher, sensitivity of Pareto solutions to the fuel unit cost was more than some parts of
figure with smaller total cost rate. Also, exergy losses of various components were obtained that conclusions illustrated
that combustion chamber has the maximum rate of exergy destruction (about 73%). Impact of ambient temperature
variation on exergy losses and efficiency for different components was studied. The conclusions illustrated that with
growing in ambient temperature, exergy efficiency of all parts decreased and exergy losses increased. Also, by rising the
ambient temperature, exergy efficiency decreased, so that an increase in temperature from 293 Kelvin to 323 Kelvin, total
exergy efficiency decreased from about 51% to 49%.

Authors: Avila Mellizo Greace Alejandra , Rozo-Gutierrez Nathaly , Forero-Motta Diana Alexa
Published: April 2020

Introducción: Los defectos congénitos son alteraciones del desarrollo que se generan en la vida intrauterina y tienen un alto impacto en la mortalidad infantil. La Organización Panamericana de Salud ha definido que la vigilancia en salud pública es una de las herramientas fundamentales para obtener estimaciones más precisas sobre la prevalencia del evento. Metodología: Estudio descriptivo retrospectivo con base en la notificación individual semanal de casos al Sistema de Vigilancia en Salud Pública (Sivigila) del evento 215 – Defectos congénitos de los años 2015, 2016 y 2017. Resultados: La notificación de defectos congénitos en Colombia ha aumentado un 39,9% entre 2015 y 2017 con una tasa de prevalencia para el último año de 106,6 casos por 10.000 nacidos vivos. Las tasas de prevalencia más altas se encontraron en cuatro grupos diferentes: 1) menores de sexo masculino, 2) pertenencia étnica indígena, 3) hijos de madres no aseguradas al sistema de salud, 4) hijos de madres con edades mayores de 35 años. Así mismo, los defectos congénitos del sistema osteomuscular, sistema circulatorio y sistema nervioso central presentaron la mayor tasa de prevalencia. Discusión: Las mayores tasas de prevalencia identificadas en algunos grupos poblacionales son consistentes con otros estudios realizados en la región, y a su vez pueden ser relacionados con las condiciones de vulnerabilidad que limitan posiblemente la falta de oportunidad y acceso a los servicios de salud.

Introducción: En el fenómeno migratorio desde Venezuela hacia Colombia, las mujeres representan una proporción significativa entre los migrantes irregulares; de ellas, las gestantes han sido priorizadas por sus condiciones particulares de vulnerabilidad. Sin embargo, se desconocen sus condiciones de salud. Objetivos: Caracterizar multidimensionalmente la situación de salud de las gestantes venezolanas migrantes irregulares, residentes en las principales ciudades receptoras del Caribe colombiano: Barranquilla y Riohacha. Metodología: Estudio descriptivo de corte transversal en 520 gestantes venezolanas migrantes irregulares, captadas por muestreo sistemático en hospitales públicos, y comunitariamente a través de búsqueda activa en bola de nieve entre agosto de 2018 y mayo de 2019. Con un cuestionario estandarizado se evaluaron los principales problemas de salud, estado nutricional, seguridad alimentaria, presencia de síntomas depresivos, accesibilidad y satisfacción con los servicios de salud. Resultados: La mitad percibía su salud durante el embarazo como buena o muy buena (53,4%). El 51,3% presentó anemia ferropénica y la mayoría algún grado de inseguridad alimentaria (87,5%). La prevalencia de síntomas depresivos clínicamente significativos fue del 32,1%. Una alta proporción reportó algún tipo de violencia por parte de su pareja (90,2%). El 25,9% requirió atención sanitaria por urgencias independiente de la atención prenatal. El 62,7% calificó la atención por urgencias como muy buena o buena, mientras que el 73,1% piensa que le brindaron la atención necesaria para su problema de salud. Conclusiones: Los principales problemas de salud en gestantes que participaron en el estudio corresponden a la inseguridad alimentaria, anemia, síntomas depresivos, violencia de pareja y ausencia de controles prenatales. Su situación de salud debe considerarse en el marco del proceso migratorio y desde los determinantes sociales de la salida, tránsito, llegada y retorno. Las medidas de atención primaria para esta población deben seguir siendo fortalecidas por el sistema de salud a nivel territorial y basadas en evidencia.
Imputación de valores perdidos y detección de valores atípicos en datos funcionales: una aplicación con datos de PM10
Authors: Meléndez Rafael , Bolívar Stevenso N , Rojano Roberto
Published: April 2020

Los datos recopilados en el monitoreo de la contaminación del aire, como PM10, se obtienen en estaciones automatizadas que generalmente contenían valores faltantes debido a fallas de la máquina, mantenimiento de rutina o errores humanos. Los conjuntos de datos incompletos pueden causar sesgo de información, por lo tanto, es importante encontrar la mejor manera de estimar estos valores faltantes para garantizar la calidad de los datos analizados. En este trabajo se evaluaron los datos de partículas PM10consideradas en el tiempo como un objeto funcional, para este caso se utilizó la base de datos de la red de monitoreo ambiental de la Corporación Ambiental de La Guajira (Corpoguajira). En este estudio hemos implementado la metodología de Jeng-Min Chiou,(2014) para imputar datos funcionales. La detección de valores atípicos de contaminantes es muy importante para el monitoreo y control de la calidad del aire. Además, hemos implementado el método de imputación de datos faltantes y detección de valores atípicos para datos funcionales. Consideramos las concentraciones de partículas PM10en las estaciones de monitoreo ambiental sobre el área de influencia de la mina de carbón a cielo abierto durante 2012. Para imputar datos faltantes funcionales, se basó en la aplicación de herramientas como el análisis de componentes principales funcional (ACPF) y los procedimientos gráficos para detectar curvas de valores atípicos como el bagplot funcional y el diagrama de caja funcional de la región de mayor densidad (HDR) por sus siglas en ingles. Los resultados indican que la estación de Barranca es una curva atípica y se observó que los intervalos imputados capturan la dinámica que se comparte con las otras trayectorias de las diferentes estaciones

Published: April 2020

The service environment of the slide gates may cause localized corrosion at welds. In this work, a failure analysis was conducted to determine the causes of the prematurecorrosion of the fillet welds before the commissioning. According to the contractor, the slide gates were manufactured in ASTM A240 Type 316L stainless steel and welded with GMAW using an ER316LSi filler metal. Test samples of the fillet weld metals were extracted from gates after a preliminary visual inspection. The samples were analyzed using ferrite number measurements, Optical Emission Spectrometry, chemical analysis, metallographic examination and Scanning Electron Microscopy with microanalysis. The analysis of results using the Schaeffler and WRC-92 constitution diagrams showed that the estimatedchemical composition of the filler metal differs with the filler metal specified in the WPS suggesting that an incorrect carbon steel filler metal was used during the construction of the gates
Analyzing the Position of Mystical Intuition, Imagination and Reason in Mola Sadra and Ibn Arabi Theosophy
Authors: Amoorezaei Farhad
Published: April 2020

The discussion about mystical intuition, imagination and reason has been a main problem for philosophers and mystics and some discussions has been made about the limits of understanding and perception of each concept.  Ibn Arabi is one of the biggest Islamic mystics and has remarkable views in this field and his works in the field of mystic are of great importance.  Sad Aldin Shirazi, Iranian philosopher from the Safavi era, known as Mola Sadra, which is one of the illuminated philosophers, has done lots of research about Ibn Arabi’s works. In this study, we compare the point of views of these two philosophers and their perception about the understanding the nature of God, while analyzing the opinions of them about reason, imagination and mystical intuition. We have concluded that Mola Sadra, as same as Ibn Arabi, considers reason the first being and the Mohhamadi truth and categorizes it and says that the reason of creatures is limited for understanding God.  In his opinion, reason gets help from feeling and imagination to compensate for this flaw which helps it in the form of mystical intuition.  Therefore, reason is not in contradiction with imagination and mystical intuition but mystical intuition grows with the help of reason and imagination.
Permanent Preservation Areas scenarios in dairy farms in the Vale do Taquari against the forest code
Authors: Daiello Caio Zart , Rempel Claudete
Published: April 2020

The Forest Code implemented innovations in the regulation of Permanent Preservation Areas (PPA), especially by authorizing the continuation of agroforestry activities in the consolidated rural areas. The present study sought to analyze the implications of these innovations by identifying the use and coverage of PPAs in five dairy farms located in the Vale do Taquari, RS, Brazil, and the subsequent application of the Forest Code rules to determine areas that must be recovered and respected on each property. The results showed that the total areas to be respected represent 10.64%, 5.10%, 59.77%, 81.63% and 98.37% of their respective PPA. These data indicated that, depending on the situation of the property, the innovations brought by the Forest Code cause a significant reduction in the ​PPA to be respected, besides leading to disparate protection measures between properties, imposing greater burdens on those in which native vegetation was grown more preserved.
Fatores Político-Econômicos do Desmatamento na Amazônia Oriental
Authors: Gazoni Jefferson Lorencini , Mota José Aroudo
Published: April 2020

Este estudo investigou as relações entre aspectos político-econômicos e o desmatamento na Amazônia Oriental, com o propósito de avaliar os principais fatores primários que contribuíram para o desmatamento recente da floresta regional ou para a sua proteção. Metodologicamente, utilizou-se de regressão múltipla com dados coletados por meio de uma série de corte (cross-section) das informações dos municípios localizados na porção oriental do bioma Amazônia, dados desses válidos para o período 2007/2008. Os resultados evidenciaram que os principais fatores associados em primeiro nível às taxas de desmatamento na região são a área agropecuária, as produções de madeira e carvão vegetal, a produção extrativista não-madeireira, a distância ao escritório regional do Ibama mais próximo, as áreas protegidas e o estoque florestal. Neste sentido, os estudos sobre o desmatamento da Amazônia devem ampliar a atenção quanto às atividades econômicas que podem proteger ao invés de destruir a floresta.

Published: April 2020

El presente artículo pretende analizar el impacto de la estrategia en las pymes de Costa Rica. Para esto, se ha iniciado con la validación y adaptación de las escalas basadas en los modelos de Porter, así como de Cameron y Quinn, lo cual constituye el objetivo fundamental del presente estudio. A partir de la revisión de literatura, se ha planteado un conjunto de hipótesis asociadas a las teorías de Miles y Snow, las cuales fueron utilizadas para la validación del constructo convergente, además, se analizó la consistencia interna, externa y de constructo. De esta forma, para realizar la validación de contenido se recurre al uso de la entrevista cognitiva. Por otro lado, la validez de constructo de la estrategia de Porter fue comprobada mediante análisis factorial exploratorio y convergente, el cual mostró como resultado el agrupamiento de los ítems según lo planteado por Porter. En este análisis se destaca, además, el hallazgo de una correlación positiva entre las estrategias de diferenciación y liderazgo en costos.

Published: April 2020

Stories have become one of the ways to provide information more effectively in so-called age of technology, the 21st century. Moreover, it is seen that advertising industry storifies what they desire to commercialize. Teaching students in a storified way enables persistence of learning. The effect of storytelling and writing, which already exists in many aspects of life, on secondary students’ anxiety has been a key concern. It has been planned to search this current topic which is not encountered in the literature and to develop a scale. It is thought that secondary school students need an instrument evaluating their story writing anxiety. In this sense, the aim of this study is to develop a scale that will evaluate secondary 7th graders’ story writing anxiety. 439 students (212 female and 227 male students) participated in the study. As a result of exploratory and confirmatory factor analyses, a valid and reliable evaluation instrument for secondary school students’ story writing anxiety was developed. As a result of the research, 5 tier scale with 26 items was formed to evaluate story writing anxiety. Cronbach Alpha value was found to be .853 and total variance explained was 57.827.

Authors: YASAN AK Nehir
Published: April 2020

This study aims to
develop the Internet Literacy Self-Efficacy Scale (ILSEF) that can be used to
examine pre-service teachers’ beliefs in their capabilities to perform recent
web functionalities. The data was collected from eight different departments
and all grade levels of the faculty of education at a state university in
Turkey. Two different samples were used to develop and validate the instrument.
The first and second samples consisted of 174 and 150 pre-service teachers,
respectively. In an effort to explore the factorial structure, exploratory and
confirmatory factor analyses were run. Construct validity was also checked by
convergent and discriminant validity. A four-factor structure with 16 items was
obtained: trustworthiness, creation, technical knowledge, and getting
information. This structure accounted for 65.40% of the total variance. The
reliability Cronbach alpha coefficients of the scale were calculated as ranging
from .90 to .71. The results provided some evidence that the scores obtained
from the Internet Literacy Self-Efficacy Scale are valid and reliable in
assessing pre-service teachers’ self-efficacy beliefs in terms of the Internet
use knowledge and skills.

Gangguan yang sering terjadi pada sistem distribusi adalah gangguan arus hubung singkat. Untuk itu sistem proteksi dipasang di penyulang gardu induk. Pada penyulang Dieng-2  periode Januari 2019- September 2019 telah terjadi trip sebanyak tujuh kali. Peralatan sistem proteksi utama pada penyulang terdiri dari over current relay (OCR), ground fault relay (GFR), dan recloser. Untuk mengetahui koordinasi system proteksi penyulang yang baik diperlukan perhitungan arus nominal trafo, reaktansi sumber, reaktansi trafo, impedansi, dan arus hubung singkat. Hasil perhitungan arus hubung singkat akan menjadi dasar dalam menentukan waktu kerja dan selisih waktu kerja (Δt) relai antara PMT outgoing dan recloser. Pada setting awal relai, terdapat relai yang bekerja  tidak sesuai koordinasi. Pengaturan ulang nilai tms relai diperlukan untuk menyesuaikan waktu kerja (Tk) 0,7 s dan 0,3 s dengan Δt 0,4 s. Sehingga relai dan recloser bekerja sesuai dengan koordinasi proteksi penyulang yang memenuhi standar PLN dan standar IEC 60255.
