ДОСЛІДЖЕННЯ МОДЕЛЕЙ РОЗПОВСЮДЖЕННЯ ІНФОРМАЦІЇ ТА ІНФОРМАЦІЙНИХ ВПЛИВІВ В СОЦІАЛЬНИХ МЕРЕЖАХ
Authors: Ulichev O. S.
Published: October 2018

Предметом вивчення в статті є процеси розповсюдження інформації та інформаційних впливів у віртуальних соціальних мережах. Метою є дослідження існуючих моделей розповсюдження інформації та інформаційних впливів у віртуальних соціальних мережах, порівняння окремих моделей, виявлення характеристик та специфічних ознак, що не враховуються в існуючих моделях. Завдання: дослідити види існуючих, раніше запропонованих, моделей для моделювання інформаційних процесів в соціальних мережах, провести порівняльний аналіз для виявлення характеристик та проявів, що не враховуються в запропонованих моделях, і в той же час можуть мати суттєвий вплив на досліджувані процеси. Використаними методами є: аналіз та синтез, емпіричні методи порівняння. Отримано наступні результати: порівняння розглянутих моделей виявляє, що більшість з них не враховують індивідуальних характеристик вузла. Класичні моделі орієнтовані на дослідження певних підгруп вузлів мережі та динаміку зміни даних підгруп, при цьому всі вузли мають однакові характеристики. Практика дослідження ситуацій в реальних умовах показує суттєвість значення та впливу на процес особистих характеристик учасників процесу інформаційного обміну. В тому числі існуючі моделі не враховують і поведінки чи стратегій, що обираються окремими вузлами в ході реалізації процесів інформаційного впливу. Висновки. Щоб узагальнити поведінку конкретних учасників мережі на всю мережу, необхідно створення єдиної теорії соціальних мереж, в рамках якої можна було б вивчати методи виявлення і опису характеристик мереж, закономірності поширення цих характеристик, створення методів, що дозволяють за структурою соціальної мережі та іншими характеристиками визначати причини взаємодій учасників. Наявність великої кількості запропонованих моделей потребує комплексного підходу до порівняння та оцінки моделей. Інформаційні впливи ботів та автоматизований підхід до процесу розповсюдження інформації втрачають свою актуальність за рахунок наявності розроблених методів для розпізнавання та нейтралізації таких впливів. В ході «живого спілкування» та інформаційних процесів між людьми – вузлами мережі вирішальне значення мають характеристики окремо взятого вузла та обрана ним поведінкова стратегія для досягнення поставленої мети. Як показує проведене дослідження – більшість існуючих моделей дані аспекти не враховує.

Forensic Evaluation of Compacted Soils using RAMCODES
Authors: Oyola-Guzmán Romer D. , Oyola-Morales Rómulo
Published: October 2018

Unexpected failure of compacted soils was explained using design curves of the Rational Methodology for Compacted Geomaterial’s Density and Strength Analysis (RAMCODES).  Forensic geotechnical evaluation, applied to a compacted soil used at a construction site, demonstrated that the bearing capacity of the soil was influenced by the water content and the dry unit weight. At the construction site, the only criterion used for quality control of the compacted soil was the minimum compaction percentage; the maximum dry unit weight (achieved using the standard Proctor test) was used when the soil was compacted with light equipment, and the maximum dry unit weight (achieved using the modified Proctor test) was used when it was compacted with heavy equipment. After changing water content conditions, the soil compacted with heavy equipment and the soil compacted with light equipment exhibited changes in bearing capacity; the soil compacted with light equipment showed a failure, whereas the soil compacted with heavy equipment did not. The causes of failure were evaluated from samples of soil analyzed in the laboratory; analysis was performed using design curves obtained through a factorial experimental design. Our analysis revealed that the criterion of minimum compaction percentage was not adequate to determine the actual mechanical performance of the soil. We sought to determine why the soil compacted with light equipment did not satisfy the bearing capacity expected after compaction, and what other actions should performed at a construction site to avoid failure of soils compacted with light equipment.

Authors: Nazarnia Hadi , Sarmasti Hadi
Published: October 2018

This study proposes a network analysis framework for characterizing infrastructure resilience in the aftermath of disasters through the use of consumers’ service disruption information. In the presented framework, the notion of “peers” is used to construct the network models of consumers experiencing service disruption in the aftermath of a disaster to understand the type and extent of infrastructure damages and specify disruption patterns. Data related to electricity disruption in Bhaktapur, Nepal, in the aftermath of the 2015 Gorkha Earthquake is used to construct the network models of consumers’ networks at different points in time in the aftermath of the disaster. The created models are then used in network analysis for examining the network topological characteristics (such as clustering) and specifying the attributes of service disruption. The contribution of this paper lie in: (i) the development and validation of a novel network from disruption information, (ii) identify the extent of infrastructure disruption, type of damage, and recoverability from changes in network topology over time.

Published: October 2018

This paper examines the prospects of using semiconductor layered A III B VI type - photovoltaic cells and the photoresistors as receptors for quantitative and qualitative measurements of carbon oxides. Carbon compounds in gaseous state form absorption bands of electromagnetic radiation in a wide range of spectrum (200 ÷ 100 000) cm-1. The light absorbed or emitted in these bands at the excitations with ionizing radiation (X, γ) or strong electric fields contain direct information about the concentration of these molecules.  The frequencies that correspond to maxima of these bands are characteristic parameters of absorbing molecules. Fundamental absorption bands of CO, CO 2 and NC have the edge of band at the border of ultraviolet-vacuum, while the emission bands d cover their full range of wave numbers from 45000 cm-1 to 10000 cm-1. Two types of radiation receptors from lamellar semiconductor type AIIIBVI photosensitive in this spectral range are studied.

Authors: OBREJA CLAUDIU , STAN GHEORGHE
Published: October 2018

The total machining time for a part produced on machining centers is influenced, besides the actual machining time, by the auxiliary times which include the automatic changing of the tools. In order to increase the productivity of machining centers, the research presented in this paper has focused on enhancing the movement speed of an automatic tool feeding system. Increasing the movement speed of the mechanism`s components has led to the appearance of unwanted side effects, such as shocks and vibrations. In order to minimize these effects, we have proposed and tested a new solution to adjust the braking regime.

Authors: BARBULESCU ANDRONELA , DEAC CRISTIAN , AVRAM LAZAR , PETRESCU VALENTIN , GLIGOR ALINA
Published: October 2018

In the current paper the authors present some experimental researches regarding the depollution through combustion of soil samples that were contaminated with hydrocarbons. Determinations were carried out on chernozem-type soils with high germinative potential, artificially polluted with an oil-derived fraction with known characteristics and a clay-type soil accidentally polluted with an oil-derived fraction of unknown composition. Several combustion tests were carried out, varying the combustion and calcination time. The tests have shown that the calcination time should be of at least 10 minutes to eliminate the pollutant, but the actual duration does not significantly influence the result.

Authors: MUREȘAN MIRCEA-VLAD , PICĂ ELENA-MARIA
Published: October 2018

This paper intends to inform the scientific and engineering community on the importance of wastewater treatment plants of small capacity, designed for rural settlements. By analysing the evolution of Romania’s population by towns, on 1st January 2010, the weight of urban population was 55.1 %, and the weight of the rural population was 44.9 % of the total population. The rural environment representing 44.9% of the total population is grouped into 2860 villages with a degree of connection to wastewater treatment plants of only 11.21 %. At the moment the design of treatment plants, regardless of the structure and size of the settlement, is performed in a non-differentiated way, using the same technological methods for urban and rural areas. The implementation of technical solutions that are use for urban areas in case of small and very small towns’ claims high investment costs and especially operational costs, the efficiency of these solutions being unsatisfactory, because of wrong adoption of sizing parameters, for example, the influent specific flow. From this paper will result, based on case studies, that the specific flow sizing treatment plants for rural areas is overrated, much too high, resulting in oversized treatment plants.

ENHANCING THE EFFICIENCY OF INDOOR LOCAL VENTILATION USING CROSS-FLOW FANS: CASE STUDY FOR A SMOKING CABIN
Authors: ANDREI DRAGOMIRESCU , ADRIAN CIOCĂNEA
Published: October 2018

The paper presents an original solution for increasing air quality and reducing energy consumption of the local indoor ventilation by using cross-flow fans. The solution is a combination between the local exhaust ventilation (LEV) technique from industry, negative-pressure isolation rooms used in hospitals, and air curtains (AC) used for isolating of indoor/outdoor spaces. The solution provides a high air flow rate at low velocity due to the high value of the flow coefficient of the cross flow fans and, in the same time, allows modular setup according to local space geometry. A case study is proposed regarding the isolation of a smoking area where smell and airborne particles appear. A 3D numerical simulation was performed, in which one cross-flow fan with long axial length was considered. The optimum air flow rate and flow pattern was obtained in order to isolate the local space. The results show that a new approach for reducing sick building syndrome could be addressed by providing modular and local ventilation using cross-flow fans.
GIS BASED DECISION SUPPORT SYSTEM FOR SEISMIC RISK IN BUCHAREST. CASE STUDY – THE HISTORICAL CENTRE
Authors: DIANA GHEORGHE , IULIANA ARMAS
Published: October 2018

Because of the increasing volume of information, problem decisions tend to be more difficult to deal with. Achieving an objective and making a suitable decision may become a real challenge. In order to better deal with decision making, decision support systems (DSS) have been developed. The decision support systems (DSS) can be used in any kind of a decision-making process and are very suitable in situations that involve a lot of stakeholders and a large number of criteria. DSS offers support in the decision-making process (how a decision should be made), and it does not focus on the result (what decision that should be made). DSS can also involve a large number of stakeholders and criteria, in the same time. A limitation of this method is that, regardless of the mathematical results, the final decision has to be made by the decision maker. Depending on the nature of the decision problem, a decision maker can use decision support systems (DSS), if the decision problem is economic or technical, and spatial decision support systems (SDSS), if the decision maker is faced with a spatial decision problem. The main objective of the present study is to apply a spatial decision support system in order to find a suitable shelter in the historical centre of Bucharest City in the post-disaster phase, in case of an earthquake occurrence. The present work represents a first step in applying SDSS in the context of the seismic risk in Bucharest. For the present paper, the SMCE Module for ILWIS 3.4 was used. The method included the following steps: structuring the problem in a decision tree, applying standardization and weighting methods to the criteria, finding suitable alternatives and choosing one of the alternatives. The results show that several buildings can be used as a shelter and among these are ‘Creditul Roman’ Bank Palace, the National History Museum and the National Bank of Romania.

Investors use financial statement information in their investment decisions. Earnings is usually the main consideration of investors in making decision. However, the increase in earnings is not always followed by positive stock price changes. It shows that in economic decision-making the investors not only need information about the company's financial condition, i.e profit, but also other information. Therefore, investors need useful tool to predict the up or rise of stock price namely earnings response coefficient which shows market reaction on earnings information published by company. If the investor perceived the information content of the announced profits as good quality then the investors will react positively to earnings anouncement.Therefore purpose of this study is to examine the effect of systematic risk, leverage and earnings persistence on earnings response coefficient at manufacturing companies listed on the Stock Exchange. The population in this study are all manufacturing companies listed on the IDX in 2015. The sample of this study is determined by the method of purposive sampling and this study obtained 56 sample companies. The study usesecondary data which is obtained from www.idx.co.id. The results of this study based on multiple regression analysis indicate that systematic risk, leverage and profit persistence have no effect on earnings response coefficient.

The polymer composites of polyaniline (PANI) with PVDF have been synthesized by polymerization method. The different composites of PANI with PVDF are obtained by adding 0.5, 1, 1.5, 2 and 2.5 N solutions of PVDF during the polymerization to get the PANI/PVDF composites. The synthesized samples of PANI and composite of PANI with PVDF polymer were characterized by using X-Ray diffraction (XRD). The dielectric properties such as dielectric constant, dielectric loss and AC conductivity for the composites of PANI/PVDF at different weight percentages are studied as a function of frequency in the range 5 Hz–35 MHz at ambient temperature. It is found that the dielectric permittivity decreased exponentially at lower frequency region up to 300 Hz and then the dielectric permittivity remains constant at higher frequency region as the frequency increased. It is also observed that the dielectric permittivity increased as the concentration of PVDF in the polymer composite increased as compared to PANI. Further, it is observed that the dielectric loss increased as a weight percentage of PVDF increased in the composite of PANI. In case of AC conductivity as the frequency increased the AC conductivity remains constant up to 6.75 MHz and afterwards it increases as frequency increased. This is due to the increase in charge carriers through the hopping mechanism in the polymer composites. It is also observed that as a weight percentage of PVDF increased the AC conductivity is also increased

In search of novel high-performance materials for use in dye-sensitized solar cells (DSSCs), we used density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations to study the geometry, electronic, and optical properties, for organic molecules. The enhancement of organic dye was done by the terminal addition with organic molecule in order to improve their electronic properties and optical absorption. The absorption is became higher than that of the original dye where the rising absorption from 1050 to 1350 approximately. Also, we found that the B3LYP functional with the 6-31G basis set gave highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels. The energy gap decreased after addition from 2.73 to 2.52 eV.

Resumen: Este estudio examina el capital social de los maestros noveles a partir del Análisis de Redes Sociales (ARS) para explorar su relación con el desarrollo profesional. El capital social se concibe como un concepto multidimensional que permite explorar la parte estructural, relacional y cognitiva de la interacción social. Para ello, se realiza un análisis de las redes egocéntricas de diez maestros noveles con el fin de estudiar sus patrones de interacción dentro de la escuela. A su vez, se realizan entrevistas semi-estructuradas para comprender la importancia y significado de las relaciones sociales, triangulando esta información con los datos estructurales de las redes sociales. Los resultados nos ayudan a entender la importancia de considerar las interacciones informales tales como las relaciones de amistad y consejo como fuente de apoyo, así como la influencia del resto de dimensiones en la mejora del desarrollo profesional de los maestros noveles. Finalmente, se discuten las implicaciones para las políticas educativas que faciliten la incorporación de los nuevos maestros y el fomento de las relaciones sociales entre los profesionales. De este modo, los programas de mentoría y las actividades informales dentro de la escuela pueden ayudar a promover las condiciones necesarias. Por otro lado, se pretenden prevenir aquellas políticas que limitan el flujo de los recursos en las organizaciones educativas, tales como las prácticas aisladas de los maestros. Abstract:This study examines the social capital of novice teachers based on the Social Network Analysis (SNA) to explore its relationships with the professional development. Social capital is conceived as a multidimensional concept that allows exploring the structural, relational and cognitive part of the social interaction. For this purpose, an analysis of the egocentric networks of ten novice teachers is carried out in order to study their patterns of interaction within the school. Additionally, semistructured interviews are conducted to understand the importance and meaning of social relationships, triangulating this information with the structural data from social networks. Results help us to understand the importance of considering informal interactions such as friendship and advice as a source of support, as well as the influence of the rest of the dimensions in improving the professional development of novice teachers. Finally, the implications for educational policies, which can facilitate the incorporation of new teachers and the development of social relationships among professionals, are discussed. Therefore, mentoring programs and informal activities within the school can help to promote the suitable conditions. On the other hand, it is intended to prevent those policies that limit the flow of resources in educational organizations, such as the isolated practices of teachers.
Un departamento de Orientación singular en un Centro Educativo que tiene la colaboración como seña de identidad

Published: October 2018

Resumen:La educación inclusiva sigue siendo un reto de nuestra agenda educativa. Su construcción pasa necesariamente por procesos de colaboración entre diferentes agentes educativos e instituciones. Uno de los profesionales que puede tener un rol clave en este contexto es el orientador. Sin embargo, los estudios muestran que la colaboración entre los departamentos de orientación y otros agentes de la comunidad educativa es limitada. En concreto, el asesoramiento para la mejora del curriculum continúa siendo una tarea pendiente. Este trabajo es un estudio de caso único que muestra el modelo de trabajo de un departamento de orientación que ha reconfigurado de forma profunda su práctica con la intención de reducir los procesos de exclusión entre el alumnado y desarrollar un trabajo más colaborativo con los docentes y el asesoramiento en lo curricular. Las técnicas de recogida de información empleadas han sido: la entrevista, el grupo de discusión y la observación participante. Los resultados muestran que la reunificación de funciones entre los miembros del departamento de orientación, la docencia, el desarrollo de una orientación inclusiva y el trabajo para la mejora de la relación familia-escuela, son piezas fundamentales en el trabajo de estos profesionales. Abstract:Inclusive education remains a challenge of our educational agenda. Its construction necessarily involves processes of collaboration between different educational agents and institutions. One of the professionals that can play a key role in this context is the counselor. However, studies show that collaboration between guidance departments and other agents of the educational community is limited. In particular, the advice for improving the curriculum continues to be an unresolved issue. This work is a unique case study that shows the working model of an guidancen department that has deeply reconfigured its practice with the intention of reducing the processes of exclusion among the students and developing a more collaborative work with the teachers and the curricular advice. The data collection techniques used were: the interview, the focus group and the participant observation. The results show that the reunification of functions among the members of the guidance deparment, the teaching, the development of an inclusive orientation and the work for the improvement of the family-school relationship, are fundamental pieces in the work of these professionals.
Actitudes hacia la ciencia del profesorado en formación de Educación Infantil y Educación Primaria
Authors: Mazas Beatriz , Bravo Torija Beatriz
Published: October 2018

Resumen:En este trabajo se examinan las actitudes hacia la ciencia de 621 estudiantes de Magisterio de Educación Infantil y Educación Primaria. Para recoger la información se empleó un cuestionario de 24 ítems en el que se incluyeron enunciados relacionados con la imagen hacia la ciencia y el medio ambiente, la ciencia escolar y la enseñanza de las ciencias. También se analizan sus actitudes en función del género, el bachillerato de procedencia, la titulación y la formación en didáctica de ciencias recibida. Los resultados muestran que la actitud hacia la ciencia y el medio ambiente en la mayoría del futuro profesorado es positiva, ya que en casi todos los ítems el número de respuestas favorables supera a las desfavorables. Sin embargo, esta tendencia cambia cuando nos referimos a la actitud frente a la ciencia escolar, donde se muestra mayor tendencia al desacuerdo, excepto cuando se pregunta si hay que aprender ciencias en la escuela. En cuanto a la actitud hacia la enseñanza de las ciencias, un 92% identifica la importancia de enseñarlas en el aula, aunque alrededor del 30% reconoce no tener los recursos y conocimientos suficientes para trabajarla con sus alumnos. La variable que influye en mayor medida en la actitud de los docentes hacia la ciencia es el bachillerato que estudiaron, apreciándose diferencias significativas en 17 de los 24 ítems, siendo más favorables en aquellos que estudiaron bachillerato científico-tecnológico que en el resto. En la titulación no se encontraron diferencias significativas entre los dos Grados participantes. Abstract: In this study, attitudes towards science of 621 Preschool and Primary preservice teachers are examined. In order to collect the information, we used a questionnaire of 24 items which included four blocks related to the image of science, science and environment, school science and science education. Their attitudes are also analyzed in terms of gender, their previous studies, their teaching degree and their teacher training in science education. The results show that the attitude towards science and, science and environment is positive in most of these future teachers, since in almost all items the number of favorable responses exceeds the number of unfavorable. However, this trend changes when referring to attitudes towards school science, which shows a disagree tendency. Just one exception is found when they make reference to the importance of learning science at school. As for science education, 92% identify the importance of teaching science in classroom, although about 30% admit not having enough resources and knowledge to work it. The variable with more influence in the teachers’ attitude towards science is their previous studies. Significant differences were observed in 17 of the 24 items, being more favorable in those who studied science and technology at high school. Non-significant differences are found between the two degrees involved in the study.

Authors: Amar Víctor
Published: October 2018

Resumen:La investigación de corte narrativo comparte la voz con las que, habitualmente, no tenían eco en el panorama académico. Escucharles de modo activo nos ayuda a comprender una situación, a aprender con ellos y a aprehender de su experiencia. Con ello, el cuento será motivo de análisis a partir del quehacer que lleva a cabo una maestra de infantil en la biblioteca de su colegio, a partir de la estimable colaboración que recibe de la familia de su alumnado. Déjame que mire un cuento es un ejercicio para aprender a partir de la práctica educativa; es una experiencia que se comparte con la intención de conocerla y mejorar. Abstract:Narrative research share similarities with which usually had no echo in the academic world.

Let me look a tale is an exercise to learn from educational practice; is an experience to share with the aim to know it and to improve it.
Aprendizaje basado en Proyectos: Una experiencia universitaria
Authors: Toledo Morales Purificación , Sánchez García José Manuel
Published: October 2018

Resumen:La finalidad de nuestra experiencia de innovación ha sido introducir en nuestras aulas universitarias la metodología de Aprendizaje Basado en Proyectos (ABP), la cual consideramos una estrategia de enseñanza en la que los estudiantes planifican, implementan y evalúan proyectos que tienen aplicaciones en el mundo real y que va más allá de lo que sucede en las aulas universitarias. Esta innovación puesta en práctica con 107 estudiantes de segundo curso del Grado de Educación Infantil de la Universidad de Sevilla (España) ha tenido como meta fomentar y desarrollar una variedad de competencias relacionadas no solo con el trabajo en equipo, sino también con habilidades y estrategias de gestión, localización, búsqueda y evaluación de información a partir de fuentes documentales electrónicas, acercándolos a la reflexión de sus propias investigaciones y la construcción de conocimientos. Aunque el ABP es una metodología difícil de aplicar en Educación Superior, los resultados obtenidos ponen de manifiesto las ventajas que ofrece este tipo de metodología y el alto nivel de satisfacción de los estudiantes participantes. Ha ofrecido interacciones óptimas entre profesores y estudiantes, se ha creado un ambiente positivo de aprendizaje en el aula facilitando la comunicación y permitiendo un mejor proceso de enseñanza y aprendizaje.
