Authors: Aguilera Eguía Raúl , Jorquera Pino Paula Jessica , Salgado Claudia Jaqueline , Flores Cherie 
Published: June 2016

Introducción: la obesidad se define como una acumulación anormal o excesiva de grasa que puede ser perjudicial para la salud, donde la expansión del volumen del tejido adiposo es secundaria a un balance energético positivo mantenido en el tiempo. Objetivo: resumir las revisiones sistemáticas Cochrane y no Cochrane que evalúen el efecto de la suplementación de calcio para la disminución de peso en personas obesas. Material y métodos: se realizó una búsqueda en la base de datos Medline (1980-septiembre 2015), Metabuscador TripDatabase y Epistemonikos (hasta septiembre 2015), Cochrane BVS (hasta septiembre 2015), se buscó de forma manual en revistas relacionadas al tema de interés, se buscaron actas de congresos, se realizó seguimiento de referencias relevantes y se contactó con expertos en el área. Resultados: la búsqueda preliminar arrojó un total de 7.163 artículos potencialmente elegibles; según los criterios de elegibilidad incluimos 2 revisiones sistemáticas de estudios clínicos aleatorizados. Conclusión: el suplemento de calcio es efectivo en la reducción de peso en personas con obesidad, presentando baja calidad de evidencia. Por tanto, es muy probable que investigaciones adicionales tengan un impacto importante en la confianza de la estimación del efecto y es probable que cambie.

Published: June 2016

Introducción: la leche es un fluido cambiante formado por lípidos, proteínas, minerales y moléculas inmunes. Las tasas de lactancia materna (LM) exclusiva se encuentran por debajo de los objetivos fijados por la Organización Mundial de la Salud (OMS), que establece que las madres deben dar el pecho de forma exclusiva durante 6 meses y suplementarla con otros alimentos durante los dos primeros años. Si se llevan a cabo esas recomendaciones, las madres y sus bebés se verían beneficiados. La leche materna modifica su composición en función de la edad del bebé, el momento del día, la dieta materna o el grado de plenitud de la glándula mamaria. Estudios recientes apuntan que existe una relación dinámica entre el estado de salud del niño y la composición de la leche de la madre, ya que, incluso, aumenta la producción de anticuerpos ante una infección activa del lactante. Objetivo: efectuar una revisión sistemática de la literatura científica a base de reunir los conocimientos actuales relacionados con las propiedades inmunológicas de la lactancia materna y de sus efectos en la salud de la madre y el niño. Métodos: se lleva a cabo una búsqueda sistemática y se seleccionan 21 artículos específicos sobre el tema, siguiendo las directrices PRISMA. Resultados: los estudios analizados muestran que la leche materna tiene gran cantidad de componentes inmunológicos que aumentan ante las necesidades del bebé. También ofrece beneficios físicos y psicológicos para la madre y el niño y supone, igualmente, un ahorro económico al disminuir los ingresos hospitalarios de los bebés, puesto que disminuye su morbilidad. Conclusiones: los bebés alimentados con leche materna tienen menos probabilidades de padecer enfermedades gastrointestinales, respiratorias, alérgicas o asma, y también previene la obesidad infantil. Además, la LM tiene efectos beneficiosos para la madre, pues disminuye el riesgo de padecer cáncer de mama, enfermedades cardiovasculares y el síndrome metabólico. Se deben aumentar las tasas de lactancia materna exclusiva, al menos hasta los 6 meses de vida.

Authors: Álvarez Cristian , Ramírez-Campillo Rodrigo , Vallejos-Rojas Andrea , Jaramillo-Gallardo Javiera , Salas Bravo Carlos , Cano-Montoya Johnattan , Celis-Morales Carlos 
Published: June 2016

Introducción: obesidad e inactividad física son importantes factores de riesgo para el desarrollo de hipertensión en adultos. No obstante, hay poca evidencia sobre el efecto de estos factores de riesgo en el desarrollo de hipertensión en población infantil. Objetivo: investigar la asociación del estado nutricional, niveles de actividad física y etnicidad con niveles de hipertensión en escolares entre 6 y 13 años de edad. Métodos: un total de 418 escolares de ascendencia étnica europea (n = 311) y mapuche (n = 107) fueron participantes de este estudio transversal. Se midió el peso, talla, índice de masa corporal (IMC) y presión arterial, utilizando protocolos estandarizados. Resultados: no se encontraron diferencias significativas en IMC, estado nutricional y presión arterial entre niños con ascendencia europea y mapuche. No obstante, la prevalencia de prehipertensión (21,3% vs. 11,1%) e hipertensión (28,9% vs. 18,6%) fue significativamente mayor en escolares mapuches en comparación con europeos, respectivamente. Escolares con ascendencia mapuche tienen un mayor riesgo de desarrollar prehipertensión o hipertensión que escolares con ascendencia europea (OR: 1,92 [1,19 a 3,06], p < 0,01). La prevalencia de hipertensión aumenta significativamente en ambos grupos étnicos con el incremento de IMC y bajos niveles de actividad física. Conclusiones: el riesgo de desarrollar prehipertensión o hipertensión es mayor en población infantil ascendiente de mapuches que ascendiente de europeos y este riesgo se ve acentuado con el incremento de obesidad y bajos niveles de actividad física.

Published: June 2016

Introducción: la obesidad es una enfermedad asociada a diferentes trastornos físicos y emocionales que inciden en la calidad de vida y que representan un problema de elevada prevalencia en el mundo. La etiología es múltiple y compleja; se ha señalado la culpa como consecuencia del sobrepeso y, al mismo tiempo, como factor asociado al aumento de peso. En México no existen instrumentos para evaluar la culpa por obesidad y sobrepeso en niños y adolescentes. Objetivos: analizar la fiabilidad y validez de la Escala de Culpa por Obesidad o Sobrepeso para Niños y Adolescentes (ECOSNA) en población de Morelia (México). Material y métodos: se elaboró una versión preliminar basada en la bibliografía que se sometió a la revisión de jueces expertos. La escala obtenida de 6 ítems se aplicó a una muestra de 1.418 estudiantes de educación básica de 7 a 15 años. Se realizó un análisis factorial confir- matorio y se estudió la relación de la escala con otras variables como autoestima, sintomatología depresiva y ansiedad. Resultados: la escala resultó unifactorial, se obtuvo un índice alfa de Cronbach de 0,853. La escala ECOSNA mostró una correlación moderada e inversa con la escala de autoestima, y directa y baja con la sintomatología depresiva y la ansiedad clínica. Conclusión: los datos empíricos indican que la escala presenta una validez y confiabilidad satisfactorias.
<p>The International Technology Education Association (ITEA): A Prominent
Voice for Technology Education</p>
Authors: Starkweather Kendall N. 
Published: June 2016

This article is one of a continuing series on professional organizations that
serve the technology professions. The first in this series on The National Association
of Industrial and Technical Teacher Educators (NAITTE) by S. D. Johnson, R. N. Evans,
and J. Stern appeared in the journal Volume XXII, Number 2, Summer/Fall 1996. This was
followed by a special section on the MVITEC in Volume XXIII, Number 1, Winter/Spring
1997, and Wright’s article on the CTTE in Volume XXIII, Number 2, Summer/Fall 1997.
Future issues will carry more such articles to provide members of the technology
professions a comprehensive portrait of professional organizations that exist throughout
the world. Some serve students, others industrial and business practitioners, and others
are devoted to teachers on various educational levels. The progress and strength of
the professions in technology rely on the dynamics of viable professional organizations.
We believe it is in the readers’ interests to participate in, contribute to, and enjoy
the professional benefits of one or more of these organizations as appropriate to the
individual’s status and needs within a technology profession. JS

Authors: Hong Jon-Chao , Lin Chan-Li , Lin Ya-Ling 
Published: June 2016

To help cultivate future talent for creating technology, the PowerTech Youth
Creativity Contest was first held in 2000 by the Taiwan Creativity Development
Association (TCDA) and the National Taiwan Normal University (NTNU). It has since been
organized regularly on a yearly basis, with the number of contending teams growing from
78 in the first year to 414 in 2006 (3-4 members each team). The categories have been
extended from the elementary school level to include junior high school categories. The
activity design adopts the project-based learning approach and aims to develop important
technological creation abilities for students, particularly with respect to knowledge
application, psychomotor skills, and creative thinking in which the planning ability,
imagination, analytical skill, and implementation ability will be developed, and some
affective domains such as persistence, high regard for efficiency, quality improvement
ability, and teamwork spirit will be cultivated through project competition and
realization. The purpose of this article is to describe the operation principles
behind the PowerTech contest from four different dimensions: (1) contest design and its
rationale, (2) contest promotion which includes the application of information
technology (IT), and the social resource identification and application. It is hoped
that the discussion of this article will be valuable as a referential basis to
organizers of similar activities.
<p>Nano Revolution – Big Impact: How Emerging Nanotechnologies Will Change
the Future of Education and Industry in America (and More Specifically in Oklahoma) An
Abbreviated Account</p>
Authors: Holley Steven E. 
Published: June 2016

Scientists are creating new and amazing materials by manipulating molecules at the
ultra- small scale of 0.1 to 100 nanometers. Nanosize super particles demonstrate
powerful and unprecedented electrical, chemical, and mechanical properties. This study
examines how nanotechnology, as the multidisciplinary engineering of novel nanomaterials
into atomically precise products, is expected to disrupt most industries. Past
industrial revolutions, driven by water power, internal combustion power, electrical
power, and computer power, have greatly affected our economy and forever changed the
course of society. Nanotechnology represents more potential power than all previous
technologies combined. The primary methodology of this study involved comparing the
current literature on developments in nanotechnology to the historical development of
electricity to assess if the nanotech revolution is reaching a true “critical mass,”
based on acceleration of technological change today and at other times in history. Data
was collected from technical and business books on nanotechnology, testimonies from
scientists before Congress, policy letters from the President’s Office of Science and
Technology, presentations at major nanotech conferences, perspective surveys from the
international to the local level, studies on the dangers and regulation of
nanotechnology, and studies on the general and scientific educational landscape of
America. Although nanotechnology is growing in national academic intensity, is
gathering public recognition, and is based on patentable science, Oklahoma and the West
South-Central Region received only 9.6 percent of nanotech funding (NSF Award
DMI-0450666, 2005). This study establishes recommendations for business and academic
planning with specific strategies, goals, and objectives for community college workforce
education in Oklahoma.
<p>Students’ Attitudes Toward STEM: Development of an Instrument for High
School STEM-Based Programs</p>
Authors: Mahoney Mark Patrick 
Published: June 2016

The intent of this study was to develop an instrument to measure the current level
of attitude that students’ exhibit toward STEM education. The Concerns-Based Adoption
Model, Taxonomy of Education Objectives – Handbook II, and other pertinent instruments
were utilized as sources of inspiration for the instrument. The selected items were
submitted to a panel of experts representative of STEM education. Initial pilot testing
refined the instrument through principal components analysis and Cronbach’s alpha
coefficients. The identified principal components aligned well with reviewed
instruments. Reliability coefficients were strong for each of the principal
components. Results of the combined analyses led to revisions of the instrument
prior to a larger comparative study – a known-group comparison. A self-identified
STEM-based high school program and a conventional college-preparatory program were
compared. Principal components analysis and Cronbach’s alpha procedures were again
applied to the data collected. The two samples were compared using three distinct
independent variables – educational location, grade level, and gender. Each independent
variable was analyzed for each principal component. MANOVA procedures were
utilized. Male students indicated a statistically significant more positive attitude
toward STEM when compared to the female students for the independent variable of gender.
The statistical significance was demonstrated specifically for the content areas of
technology and engineering. The results of the data analysis supported the proposed
hypothesis. Based upon extensive review of the varied data analysis procedures
implemented, the students’ attitudes towards the STEM instrument demonstrated positive
examples of validity and reliability.
<p>Is the Technology a New Way of Thinking?</p>
Authors: Sanduk Mohammed 
Published: June 2016

In his consideration of thought development, Auguste Comte proposed a three-stage
model, in which the mechanism of development may lead to new types of thought. So the
process that led to a philosophy of science may be repeated to create a new type of
thought. The thought development is attributed to a process of accumulation of
challenged but unanswered questions, followed by a decline of interest in that type of
thinking. The science stage presented a huge accumulation of achievements, but at
the same time it confronts huge challenges. The present work is a theoretical analysis
for what is happening because of these challenges. The author believes that the
technology may be regarded as a fourth stage for Comte’s model. The technology stage
corresponds to globalization as a social stage. Technology has its own methodological
way. Owing to the connection between the technology and human need, the development of
technology follows a Darwinian evolution model. The process of technology selection that
leads to development is the user selection, which corresponds to Charles Darwin’s
natural selection.
<p>The Current State Of Wireless Information Technology In The Construction
Industry In Ohio</p>
Authors: Atalah Alan , Seymour Aaron 
Published: June 2016

Construction projects are increasingly getting complex and fragmented in nature,
yet contractors persistently face shortened project durations and reduced budgets.
Timely delivery of accurate and reliable information among all project participants is
critical and important because information is the foundation upon which decisions are
made and projects are estimated, planned, monitored, and controlled. Recent developments
in technology promise to introduce efficiencies that were not previously available to
the industry. This study seeks to identify the current state of wireless information
technology through the analysis of quantitative data from a web-based survey that
represents the views of the respondents on the usage and interest in wireless
technology. The study suggests that the level of interest in wireless technology is
much higher than the level of use. Wireless technology enhanced the skills,
productivity, and customer service of the participants, but did not improve their
ability to negotiate projects and monitor project costs. The respondents believe that
the return on investment is not a barrier; slow download speeds and durability are the
largest barriers keeping people from using wireless technology.

Rock Mechanical Properties of Shallow Unconsolidated Sandstone Formations
Authors: Ramcharitar Kamlesh , Hosein Raffie 
Published: June 2016

Abstract
Rock mechanical properties, such as the Poisson's ratio, Bulk, Shear and Young's moduli are required for various oilfield operations such as seismic processing, reservoir simulation studies, and hydraulic fracturing for sand control. These properties are usually determined from compressional (P) and shear (S) wave velocities which can be captured by the dipole sonic logging tool. For unconsolidated rocks (shallower than 6000 ft), the P and S-wave velocities are difficult to predict due to the dispersive nature of these rocks. Also, the available correlations in the open literature to determine these parameters should be used with caution since these were developed mainly for deeper formations.
In this study, we compared the sonic wave velocities empirically predicted by Castagna et al., Eberhart-Phillips and Han with the logged sonic wave velocities across the Cruse Formation for eight onshore wells in South-Western Trinidad. We also investigated more suitable methods of matching the logged velocities across the Cruse, by developing new empirical models and an analytical method (Hertz-Mindlin contact model) to account for the unconsolidated rocks. The basic input data required for predicting the sonic velocities and dynamic rock mechanical properties were porosity, clay content and bulk density which were taken from the log data. The models for obtaining the static rock mechanical properties were tested against the results of Mini-Frac tests in two offset wells in the Cruse.
The Artificial Neural Network (ANN) empirical method was shown to be best suited for predicting the dynamic rock mechanical properties for the Cruse Formation, since Average Absolute Errors (AAE) of 3 and 6 % were obtained in matching the P and S-wave velocities respectively. Similarly, the AAE obtained from applying the three empirical correlations were worse than 17 and 30 %. This error was generally observed to lessen for wells which encountered the Cruse at greater depths. While AAE of 6 and 12 % were obtained from applying the analytical method, reservoir depletion was found to significantly affect the results of the modeling due to the implied presence of hard-to-predict free gas saturations. Also, it was found that the analytical method is the only viable procedure to predict the static rock mechanical properties in lieu of laboratory core tests. The analytical method has been tuned in this study using True Vertical Depth (TVD) as a correlation parameter for the first time, and it can generally be used to estimate both the dynamic and static rock mechanical properties of the Cruse Formation for future oilfield operations.
