Medios de comunicación y consumo de alcohol en adolescentes: ¿qué dicen los expertos?
Authors: Suárez Relinque Cristian , Del Moral Gonzalo , Musitu Gonzalo , Villarreal-González María 
Published: November 2017

El objetivo del presente estudio es conocer la opinión de profesionales expertos en adolescencia, familia, escuela, medios de comunicación y políticas locales, respecto al rol que desempeñan los medios de comunicación en el consumo de alcohol en los adolescentes. Se ha realizado una investigación cualitativa siguiendo el esquema propuesto por la Teoría Fundamentada (Grounded Theory) (Glaser y Strauss, 1967). La información se ha obtenido a partir de Grupos de Discusión guiados por entrevistas semiestructuradas. Participaron en el estudio 32 expertos nacionales. La conclusión principal es que los expertos entrevistados perciben que los medios de comunicación desempeñan un importante rol educativo en el consumo de alcohol e identifican siete aspectos clave (subcategorías) en el comportamiento de los medios que suponen factores de riesgo para el consumo en los adolescentes, los cuales se agrupan en tres categorías (modelado en hábitos no saludables, imagen sesgada del adolescente y falta de rigor en la información).
Sex practices and knowledge about HIV/AIDS among drug users in a low-income urban community of Costa Rica
Authors: Chacón Ortiz Manuel , Barrantes Kenia , Achí Rosario , Comerford Mary , McCoy, Clyde 
Published: November 2017

HIV/AIDS transmission among drug users is associated with education, sex practices and substance use. This study examined 159 drugs users’ knowledge, beliefs and sex behavior related to HIV/AIDS risk in Costa Rica. Results showed considerable use of marihuana, alcohol, crack and cocaine and a very low lifetime incidence of other drugs. All substance use patterns were higher than national averages. Respondents showed a high level of knowledge about HIV/AIDS transmission and prevention. However, there did not seem to be a relationship between knowledge and practice. Unprotected sex was common and having an HIV/AIDS test was not a regular practice. Knowledge about HIV/AIDS is not a determinant factor for condom use among this group. It is concluded that having the proper knowledge about transmission and prevention does not guarantee safe sex practices. Further research and public health evidence based practices for HIV/AIDS prevention should target drug user population

Published: November 2017

Aunque no se trata de un fenómeno reciente, la Nomofobia (No Mobile Phone Phobia) entendida como una adicción comportamental que implica un alto temor a quedarse sin teléfono móvil, está siendo objeto de investigación desde diferentes disciplinas dada las importantes consecuencias que se están observando entre la población más joven. Sin embargo, son pocos los instrumentos capaces de medir esta adicción no reconocida como tal por el DSM-V. En el presente trabajo se ha llevado a cabo el proceso de adaptación y validación de la escala de medición de la Nomofobia de Yildirim y Correia. Para ello se procedió a una adaptación lingüística y cultural de la misma, seguida de una revisión por parte de expertos en la materia. La decisión del grupo de expertos supuso una modificación de la redacción y la inclusión de un nuevo ítem. La escala resultante se aplicó a una muestra de 372 estudiantes de Educación Secundaria Obligatoria, en institutos públicos de la provincia de Alicante. Los resultados permitieron la validación de la escala objeto de este estudio.

Familiar consequences of pathological gambling: a critical review / Repercusiones familiares del juego patológico: una revisión crítica
Authors: Autor Autor 
Published: November 2017

En este trabajo se presenta un análisis de las principales repercusiones familiares del juego patológico. Se revisan los estudios sobre las consecuencias físicas y psicológicas observadas en la pareja –habitualmente, la mujer– del jugador, en los hijos y, en el caso de ludópatas adolescentes, en los padres. Los resultados de la revisión ponen de manifiesto que el impacto del juego patológico va más allá del paciente afectado y se observa la presencia de repercusiones concretas en los familiares cercanos. Sin embargo, los resultados obtenidos hasta la fecha no son concluyentes. Se carece de estudios empíricos rigurosos sobre este tema. Por último, se comentan las implicaciones clínicas de las repercusiones familiares para el tratamiento del juego patológico. AbstractIn this paper, the main family consequences of pathological gambling are described. Studies about physical and psychological consequences in gambler’s partners –primarily, females–, in children and, in the case of adolescent pathological gamblers, in parents, are reviewed. Results show that the family impact of pathological gambling is very important. However, the results of studies are not conclusive. Finally, clinical implications of these family consequences for pathological gambling treatment are commented upon.
Clinical aspects of gambling: a non conventional addiction / Aspectos clínicos de la conducta adictiva al juego: una de las adicciones no convencionales
Authors: Vacca Rodríguez Ricardo 
Published: November 2017

En la actualidad el campo de las adicciones se ha ampliado ante la aparición de una patología similar a las adicciones a las sustancias químicas pero donde no existe una sustancia psicoactiva, denominadas conductas adictivas, o adicciones no convencionales. Através de los últimos años se ha comprobado que ciertos individuos son más sensibles a desarrollar una conducta adictiva hacia objetos actividades o personas o un mismo individuo puede desarrollar unas conductas adictivas y a la vez una adicción a drogas. En cambio otras pueden desarrollar con mayor facilidad una conducta adictiva a las actividades, a las máquinas u objetos o a las personas de manera exclusiva, permanente y/o sucesiva, a la cual se le denomina personalidad adictógena. Una de estas patologías es la conducta adictiva al juego llamada también ludopatía y es la que desarrollaremos en este trabajo. Se presentan las características clínicas del trastorno, las diferentes etapas del proceso adictivo, incidiendo en los mecanismos cognitivos. Se propone una clasificación del adicto al juego. AbstractThe addicionology field is more extensive these days than many years ago because it comes up pathology some at chemical substance addiction but there aren't a psychoactive substance in use, this pathology is calling for the specialists "addictive behaviors" or none conventional addictions. Through the years in clinical and hospitals we can see that some people are more sensitive to develop an addictive behavior besides a chemical addiction, and others can develop easily an addiction to the activities, machines, objects or persons of exclusive permanent and successive way. One of this interesting and complexity pathology is the gambler addictive behavior, calling also ludopatia and the following are the clinical profile. Characteristics of gambling are presented, the stages of the addictive process, especially on cognitive mechanisms. A classification of gambler is presented.

Published: November 2017

La evidencia empírica ha mostrado que el consumo abusivo de alcohol puede repercutir negativamente en determinadas funciones cognitivas.El objetivo de este artículo ha sido analizar si existe relación entre el consumo de alcohol y determinadas habilidades cognitivas (memoria, percepción y razonamiento) en jóvenes universitarias. Se han utilizado varios cuestionarios para recoger el perfil adictivo de las jóvenes y para evaluar el rendimiento de los sujetos en tareas que implican ciertas habilidades cognitivas. Participaron 100 mujeres, de entre 18 y 25 años, distribuidas en dos grupos: consumidoras de riesgo (n=31) y consumidoras de bajo riesgo (n=69), siguiendo los criterios de la OMS. En cuanto a losresultados, por un lado, el grupo de las consumidoras de riesgo mostró un patrón de consumo más grave en términos de uso de otras sustancias, frecuencia de consumo y porcentajes de cumplimiento de criterios de abuso. Por otro lado, en cuanto a las habilidades cognitivas se encontraron diferencias significativas entre grupos en razonamiento abstracto y en percepción. Los resultados muestran tendencias de cómo el consumo abusivo de alcohol podría afectar al funcionamiento cognitivo de las mujeres jóvenes. Futuros estudios podrían profundizar en estos déficits y aportar luz en la mejora de las técnicas terapéuticas y preventivas en este campo. Abstract Empirical evidence has shown that alcohol abuse may negatively affect to certain cognitive functions. The aim of this paper was to analyze the relationship between alcohol consumption and certain cognitive abilities (memory, perception and reasoning) in university students. Two questionnaires were used to assess the young women addictive profile and to assess several the subjects’ performance on tasks involving cognitive skills. A total of 100 women between 18 and 25 years, divided into two groups following the WHO criteria was involved in the study: consumers at risk (n = 31) and low-risk users (n = 69). In terms of results, on the one hand, the consumers at risk group showed a more severe pattern of consumption in terms of substance, frequency of consumption and rates of fulfill criteria for abuse. Furthermore, in terms of cognitive abilities significant differences between groups in abstract reasoning and perception were found. The results show trends of how alcohol abuse might affect cognitive functioning in young women. Future studies could deepen the deficit and bring light into the improvement of preventive and therapeutic techniques in this field.

El objetivo de este trabajo consistió en desarrollar y analizar las propiedades psicométricas de una escala multidimensional para evaluar los conocimientos relacionados con el VIH/SIDA en adolescentes (Escala de conocimientos sobre VIH/SIDA, HIV-KS). Tras un estudio piloto se administró un cuestionario de 48 ítems a una muestra de 14 centros escolares de 5 provincias españolas. Se puso a prueba la estructura teórica del cuestionario mediante un análisis de componentes principales al que se le aplicó un análisis confirmatorio. Se analizó la validez convergente y discriminante y la fiabilidad de la escala y, finalmente, se procedió a comprobar su invarianza factorial en función del género y la edad con una muestra de 1216 participantes. La versión final de HIV-KS estuvo compuesta por 10 ítems distribuidos en 3 factores principales. Los factores incluidos fueron (1) Transmisión oral del VIH, (2) Efectos del VIH, y (3) Otras vías de transmisión del VIH. La escala HIV-KS muestra invarianza en función del género y la edad y buena consistencia interna. HIV-KS es una escala capaz de evaluar de forma rápida y eficaz el grado de conocimientos sobre VIH/SIDA en población adolescente. Absctract This paper aims to describe the development process, the factor structure, the reliability and validity of a multidimensional scale to measure HIV/AIDS-related knowledge for adolescents (HIV/AIDS Knowledge Scale, HIV-KS). After a pilot study of the items, a questionnaire of 28 items was administered to a sample from 14 different schools in 5 counties in Spain. Firstly, Principal-component analysis was used: first, to test a theory-driven structure and second, to develop an empirically derived factor structure for HIV-KS, which was tested with a confirmatory factor analysis. Secondly, reliability and convergent and discriminant validity were examined and finally, the factorial invariance was analyzed according to gender and age with a sample of 1,216 Spanish adolescents.The final version of the HIV-KS consists of 10 items distributed across three major factors. The factors included are: (1) HIV oral transmission, (2) HIV effects, and (3) other HIV transmission methods. The HIV-KS is invariant across gender and age and shows good validity and internal reliability. HIV-KS is a capable and parsimonious self-report scale for assessing main aspects of HIV/AIDS-related knowledge for adolescents.
Molecular Modeling of Organic Materials for Flow Simulation and Digital Source-Rock Physics
Authors: Feng Feng , Akkutlu I. Yucel 
Published: November 2017

Abstract
Model development for organic materials such as kerogen and bitumen using molecular building blocks is an important and fast-evolving science for source rock characterization. However, the size of the current models is much smaller than the representative elementary volume of organic in order to describe the macroscopic quantities such as diffusion coefficents and permeability. In addition, pore size distribution of the current models is skewed towards the lower end such that the predicted quantities are inaccurate.
A new methodology is presented to build larger organic models to overcome the scale-dependence issue. A solid organic skeleton can be built using 3D tomographs which can be obtained from high-resolution microscopy such as TEM. The skeleton is populated with atoms distributed based on the organic matters maturity and elemental composition. As part of the new methodology to build larger organic model, we replace the atoms that make up the skeleton with an average representative atom whose bond length with the surrounding representative atoms is tuned to maintain the solid density and the structure of the skeleton unchanged. The average force field parameters are calculated based on kerogen's elemental composition. Permeability of this simplified organic model is measured using molecular dynamics simulation of steady-state fluid flow through the model pore-network.
When the transport simulation results of the simplified organic model are compared to its counterpart carrying exact molecular description, the simplified model is accurate for the calculations of permeability, tortuosity, and saturations and reduced the computational cost significantly. The simplified model can be applied to large samples and plugged into the existing digital rock workflows, to utilize meaningful pore connection information provided from tomograhy.

Published: November 2017

Abstract
This paper describes the relationship between visual attention and eye blink frequency. In an experiment, we prompted the activation of a subject’s visual attention and examined the influence of visual attention (as measured using electrodermal activity (EDA), which is meaningfully correlated with visual attention) on the subject’s eye blink frequency. Experimental results show that engagement of visual attention decreased eye blink frequency and that when visual attention was not activated, eye blink frequency increased. Knowledge of this relationship provides a technique using EDA to objectively determining a subject’s visual attention status.
SMART SENSING SYSTEM FOR ENHANCEING THE RELIABILITY OF POWER ELECTRONIC DEVICES USED IN WIND TURBINES

Published: November 2017

Abstract
Reliability of modern power systems, in particular those use wind and solar energies, is affected by the relatively short lifetime of the associated power electronic converters (PECs). Thermal stress has been identified as one of the commonest causes for failures in PECs. However, existing thermal monitoring systems are expensive, bulky and with no intelligent capabilities, which limit their full acceptance as monitoring and control tools in operational power plants. This work presents autonomous and inexpensive microcontroller-based system for monitoring and predicting thermal behaviour of switching devices used in PECs. System’s inputs are non-intrusively measured voltages and currents drawn by those devices while in operation. The developed system also determines lifetime consumption and has the ability to communicate with external monitoring and control systems e.g. supervisory, control and data acquisition (SCADA) platforms. The performance of the developed system was critically assessed and compared with high-resolution thermal imaging camera. Good agreement between both systems was achieved and the inexpensive developed system was found to have an accuracy of 95%.
INITIAL ALIGNMENT OF FIBER-OPTIC INERTIAL NAVIGATION SYSTEM WITH LARGE MISALIGNMENT ANGLES BASED ON GENERALIZED PROPORTIONAL-INTEGRAL-DERIVATIVE FILTER
Authors: Ali Rahgoshay Mohammad , Karimaghaie Paknoosh , Shabaninia Fereidoon 
Published: November 2017

Abstract
Initial alignment in the presence of large misalignment angles is a critical issue in strapdown inertial navigation systems. The large initial misalignment angle adversely affects the accuracy and rapidness of the alignment process. In this paper a novel robust alignment approach is proposed based on a generalized proportional-integral-derivative filter. The proposed alignment approach has some significant advantages compared to the standard Kalman filter based alignment method. This method increases the accuracy and the convergence speed of the alignment process in the large misalignment angles problem. Experimental results also, verify the prominent performance of the presented approach in comparison to conventional standard Kalman filter based alignment method.

Published: November 2017

Abstract
This paper describes the hardware implementation methodologies of fixed point binary division algorithms. The implementations have been extended for the execution of the reciprocal of the binary numbers. Radix-2 (binary) implementations of digit recurrence and multiplicative based methods have been considered for comparison. Functionality of the algorithms have been verified in Verilog hardware description language (HDL) and synthesized in Xilinx ISE 8.2i targeting the device xc4vlx15-12sf363 of Virtex4 family. Implementation was done for both signed and unsigned number systems, having bit width of operands vary as an exponential function of 2n, where n=2 to 5. Performance parameters have been calculated in terms of clock frequency, FPGA slice utilization, latency and power consumption. Implementation results indicate that multiplicative based algorithm is superior in terms of latency, while digit recurrence algorithms are consuming low power along-with less area overhead.

Published: November 2017

Abstract
Microorganisms are contained in all foods, some of them don’t pose a risk for consumers, but many others became pathogenic, because of bad conservation or expired dates. Food will be degraded when the number of microorganisms became very large. The focus in this paper will be on the design of an electronic nose used in detecting rotten food. This nose is applied to detect bad odor diffused by rotten beef, and rotten chicken those meat have almost the same odor at rottenness which is not easily identified by human. Durations and gases emit of its rotten are determined by the pattern recognition methods PCA (Principal Components Analysis) for classification and DFA (Discriminate factorial analysis) for dating, and we will be identify between those rotten meat by DFA method.
