lifetime, with the aim of improving knowledge, skills and competencies. These

activities can be undertaken in formal, non-formal as well as informal learning

settings. From this point of view, Anadolu University e-Certificate Programs

are national scale platform and have been developed as a solution to the need

for lifelong learning in Turkey.

In 2016,

upon the Ministry of Labour, Social Services and Family’s request, an OHS e-Certificate

Program for Employer and the Representative of Employer, who have a workforce

of fewer than 50 workers and a workplace

that is classified as “less dangerous” has been designed by Anadolu University.

This

research is designed to reveal the tendencies within the Occupational Health

and Safety e-Certificate Program, which has almost 80,000 participants since

2016. The average age of participants is 39 and 65.3% are graduates of higher

education and 51.4% are employers. Participants have indicated that they are

most likely to benefit from the course book during their study; 80.7% of them

stated that they will re-participate in such course which is conducted through

open and distance learning.

A Trial to Predict the Diurnal Global Solar Irradiance Received On A Horizontal Plane for Clear Days in Terms of The Solar Angles.
Authors: Shaban Samia Sayed
Published: September 2019

A general distribution function is suggested to predict both symmetrical and asymmetric diurnal global solar irradiance q (t) W/m2 received on a horizontal surface, where “t” is the local day time "h" .The distribution is given in terms of well-established parameters, namely: td :- the length of the solar day expressed in term of the solar angles.

tmax :- the time of the day at which the irradiance reaches its maximum value qmax W/m2 for symmetrical distribution  tmax =   i.e.  it occurs at the midday time.

td , tmax and qmax are taken as parameters.

The suggested expression can be easily integrated along the length of the day time. This gives the daily totals of the received solar energy per unit horizontal area.This is of vital technical importance for solar energy exploitations and applications.  Comparison between computed according to the present model and published experimental meteorological data in Barcelona (Spain), Hong Kong (China), Jeddah and Makah (Saudi Arabia) is given as illustrative examples. Comparison with the published trials for the same locations is also clarified. The introduced model itself gives good fitting for the intermediate interval points of the local day time which is the more effective region.
Prevalence of malignancy in masses from the mammary gland region of dogs with single or multiple masses
Authors: Litterine-Kaufman John , Casale Sue A. , Mouser Pamela J.
Published: September 2019

OBJECTIVE

To determine the prevalence of malignancy in masses from the mammary gland region of dogs with single or multiple masses.

ANIMALS

95 female dogs from which mammary gland masses had been excised.

PROCEDURES

Medical records of all female dogs from which mammary gland tissue was submitted to the Angell Animal Medical Center Pathology Department from 2009 through 2014 were reviewed. For each dog, data were obtained on breed, body weight, age, reproductive status, and number, location, and histologic classification of masses. The prevalence of malignancy was compared between dogs with single versus multiple masses and among the 5 pairs of mammary glands. Dogs with single versus multiple masses were also compared with respect to age and reproductive status.

RESULTS

Among 161 evaluated masses, 137 (85%) were classified as benign or nonneoplastic and 24 (15%) as malignant. Five of 95 (5%) dogs had masses that were not of mammary gland origin. Age, reproductive status, and quantity of masses (single vs multiple) were not significantly associated with the prevalence of malignancy. The prevalence of malignancy in masses from the fourth (caudal abdominal) mammary gland was significantly lower than that in the other 4 mammary glands combined.

CONCLUSIONS AND CLINICAL RELEVANCE

Dogs with multiple masses in the mammary gland region were not significantly more likely than dogs with single masses to have a malignancy, suggesting that these 2 groups could be managed similarly. Further studies are needed to evaluate the clinical relevance of the lower prevalence of malignancy in masses from the fourth mammary gland.

Nutraceutical is food for health with functions of preventive, promotive, rehabilitation, aesthetic, intelligence to curative. Nutraceuticals as food products can have a contemporary value, which is a trend or extraordinary circumstance that attracts consumers because of its function as a supplement, functional food, medical food, and genetically engineered food so that it penetrates the world market without limits. Nutraceuticals that are contemporary make it easy to achieve the goals of health care by using the "nutraceuticals" approach because the client wishes to himself with a high level of confidence in the benefits of the product for health and therefore uses it. Potential compound for nutraceuticals is secondary metabolites because it has multipotential for health, but specific to certain functions. Secondary metabolites, generally sourced from low plants and animals, because these biological groups do not have a perfect secretion system so that metabolites resulting from secondary metabolism are stored in cells and tissues properly, with several functions, among others, for defense and attractiveness of the biological. Some of the classes and compounds of plant secondary metabolites that are known to have potential for nutraceuticals are Terpenoids, Terpenoids non-Carotenoids, Polyphenolics, Phenolic Acids, Non-Flavonoid Polyphenolics, Glucosinolates, Thiosulphinates, Phytosterols, Anthraquinones, Glucosamines, Octacosanolines, Characticines, Chines) Pectin, Pigments, Tocotrienols and Tocopherols, Ubiquinon and -Lipoic Acid. Furthermore, some contemporary nutraceuticals are Spiruline, Broccoli, Aloe Vera Gel and Aloe Juice, Soyfoods, Omega-3- Fatty Acids, Pomegranate Juice, Walnuts, and Organic Mushroom Nutrace.
Magneto – thermoelectric Effects in Compositional Superlattice in the Presence of Electromagnetic Wave
Authors: Thu Hang Dao , Thi Hoa Nguyen , Thi Thanh Nhan Nguyen , Quang Bau Nguyen
Published: September 2019

Ettingshausen coefficient (EC) in the compositional semiconductor superlattice under the influence of electromagnetic wave (EMW) is surveyed by using the quantum kinetic equation for electrons.  The analytical expressions of the Ettingshausen coefficient are numerically calculated for the GaAs/AlGaAs compositional semiconductor superlattice. It have been showed that the appearance of EMW has changed the EC’s value and the EC decreases nonlinearly when the temperature increases. Studying the dependence of EC on the magnetic field, we discovered that the resonance peaks have appeared and the superlattice period strongly affects the Ettingshausen coefficient.
Electrochemical properties of Fe2O3/AB based composite electrodes in alkaline solution
Authors: Tuan Anh Trinh , Thi Hang Bui
Published: September 2019

To find a suitable material for Fe-air battery anode, Fe2O3 nanoparticles (nm) and microparticles (µm) were used as active materials and Acetylene Black carbon (AB) as additive to prepare Fe2O3/AB composites. The effect of grain size of iron oxide particles and additives on the electrochemical behavior of Fe2O3/AB composite electrodes in alkaline solution have been investigated using cyclic voltammetry (CV), galvanostatic cycling and electrochemical impedance spectroscopy (EIS) measurements. Iron oxide nanoparticles provided better cyclability than iron oxide microparticles. Impedance of electrode increased during cycling but the nm-Fe2O3/AB electrode gave smaller resistance than µm-Fe2O3/AB one. The additives showed strongly effects on the electrochemical behaviors of iron oxide electrodes. The AB additive enhanced the electric conductivity of Fe2O3/AB electrode and thus increased the redox reaction rate of iron oxide while K2S interacted and broke down the passive layer leading to improved cyclability and giving higher capacity for Fe2O3/AB electrodes.
Optical Simulation of Planar CH3NH3PbI3 Perovskite Solar Cells
Authors: Duc Cuong Nguyen
Published: September 2019

In this work, optical simulation results of planar CH3NH3PbI3 solar cells using a MATLAB script developed by McGehee’s group (Stanford University) will be presented. The device structure is FTO/HEL/AL/ETL/LiF/Al, where HEL is a hole-extraction layer, AL is an active layer (CH3NH3PbI3), and EEL is an electron-extraction layer. This MATLAB script uses the transfer matrix method, where transmission and reflection are calculated for each interface in the stack as well as attenuation in each layer. The wavelength-dependent optical constants (n and k) of each layer were measured by spectroscopic ellipsometry (SE). The exciton generation rates within the active layer were calculated and with an assumption that the Internal Quantum Efficiency (IQE) equals 100% at all wavelengths, the predicted short-circuit currents (JSC) were also estimated. These results show a good agreement with the experimental values of JSC measured on real devices.

Brain metastases from cervical cancer reduce longevity independent of overall tumor burden
Authors: Takayanagi Ariel , Florence T. J. , Hariri Omid R. , Armstrong Abigail , Yazdian Pouria , Sumida Andrew , Quadri Syed A. , Cohen Joshua , Tehrani Omid S.
Published: September 2019

Background:

Isolated brain metastasis (IBM) from cervical cancer is a very rare encounter in neurosurgery. We sought to understand how patients with isolated brain metastases differ from those with metastases in the setting of widespread disease.

Methods:

A systematic review was completed using PubMed and the Cochrane Library. Patients with isolated brain metastases (IBM) and non-isolated brain metastases (NIBM, or brain metastases in the setting of disseminated disease), were compared. Two-sided statistical tests were used to determine significance. Survival function was carried out using the Kaplan–Meier method.

Results:

A total of 89 patients, 25 with IBM and 64 with NIBM, were identified. The time interval between initial diagnosis of cervical cancer and diagnosis of brain lesion was significantly shorter in the IBM group (median 7.5 vs. 20.05 months, and IBM vs. NIBM, respectively; P = 0.006). Overall survival from initial diagnosis of cervical cancer was significantly shorter for the IBM group versus the NIBM group (7.63 vs. 26.3 months, respectively; P = 0.0005). Data demonstrate a 3.4-fold reduction of median life expectancy to 7.63 months. Survival after diagnosis of brain metastases did not differ between groups (median, IBM 7 months vs. NIBM 4 months, P = 0.08).

Conclusion:

Taken together, our data suggest that for cervical cancer patients with brain metastasis intracranial metastasis itself (and not overall tumor burden) represent a sentinel event in limiting longevity. While the present study is underpowered to compare treatment options directly, further work should be focused on determining the optimal treatment for these patients.
The Role of Object Design in the Creation of Ani­mation Imagery. Art Analysis Experience
Authors: Parkhomenko Yana A. , Lugovtsev Anatoly Yu.
Published: September 2019

The article’s problematics relate to the field of theoretical understanding of the emergent deve­lopment of 3D animation in modern culture, its technological, artistic, commercial features. The article focuses on specific features of character design and the influence of the character’s audiovisual image on the aesthetic imagery of the screen work. The study aims to distinguish the concepts of “character type”, “visual imagery”, “audiovi­sual imagery”, “artistic ima­gery” and to substantiate the semantic relationships between them. The authors uphold the belonging of character design to the field of object design, identify the main phases of desig­ning the audiovisual imagery of the character object, and determine its structural role in transmedia projects. In the process of consi­deration of these aspects, the article involves materials from interviews and speeches by artists Alexander Petrov, Mikhail Tumelya, and Maxim Kostenko.

Via the deductive method, the article highlights the components of the screen artistic imagery in terms of subject-spatial content. In the context of solving certain problems, a comparative analysis of character ensembles in various techniques is carried out using examples of national and foreign animation. This analysis reveals the main trends in the development of artistic space of the screen work. The article also covers commercial, technological and aesthetic aspects of character development in modern 3D animation.

The conclusions of this study provide the conso­lidation of the term “object design” in the art field and can be further used both in analytical work and in the educational process in the areas of history and theory of art, media and multimedia directing theory and practice.
A.F. Mantel’s Art Collection in Museums of the Volga Region: Reconstruction Experience
Authors: Ulemnova Olga L.
Published: September 2019

A characteristic feature of the artistic life of Russia at the turn of the 19th—20th centuries was the growth in the number of private art collections and the expansion of the social composition of collectors due to the addition of industrialists, merchants and intellectuals. After the Russian Revolution of 1917, these collections became one of the important sources in the formation of art collections of metropolitan and provincial museums of Russia. The article is devoted to one of the most interesting private collections of the Kazan province — the collection of A.F. Mantel, formed at the beginning of the 20th century from paintings and graphics by the leading masters of the World of Art association: A.N. Benois, I.Ya. Bilibin, A.F. Gaush, B.M. Kustodiev, D.I. Mitrokhin, G.I. Narbut, N.K. Roerich and others. The article reveals the fates of once famous works of the artists from the World of Art association, which were shown at the association’s exhibitions and published in well-known books, magazines and almanacs such as Apollo, Libra, Rosehip, At Dawn and others. A.F. Mantel’s collection played an important role in the formation of museums in several cities of the Volga region — Kazan, Tetyushi, Kozmodemyansk — becoming one of the sources of contemporary national art collections. Due to various reasons, the most of the collection, including the part received by museums, was lost in the late 1910s — 1930s. Relying on archival and literary sources and museum collections, the author, for the first time, managed to restore, with a high degree of accuracy, the composition of the part of A.F. Mantel’s collection that was purchased for museums of Tetyushi and Kozmodemyansk, and to clarify the composition of the Kazan Museum’s collection.

The present study details the women employment and the overwhelming potential help for women to get the economic power and to change a gender connection on the employment market. Working women pick up a considerable measure of new skill and abilities associated with driving an organization as well as with personal improvement. Besides, they also conceded that more prominent support women in the market may contribute to defeat a stereotypical picture of woman as a mother and spouse. This is fought to be principally a result of structural shifts in the economy, changing effect of wage and substitution effects and an increase in instruction levels of women in the populace. Our results also suggest that development without any other person's information is not sufficient to increase women's economic activity, but instead the dynamics of development matter. These findings are especially imperative to help design policies to enhance women's work force cooperation rate so that India can take complete favorable position of its upcoming demographic dividend.

Heart Attacks are the real reason for death on the planet today, especially in India. The need to anticipate this is a noteworthy need for enhancing the nation's healthcare services. Exact and exact forecast of the coronary illness for the most part relies upon Electrocardiogram (ECG) information and clinical information. These information's must be sustained to a non-direct ailment expectation demonstrate. This non-straight heart work observing module must have the capacity to distinguish arrhythmias, for example, tachycardia, bradycardia, myocardial localized necrosis, atrial, ventricular fibrillation, atrial ventricular ripples and PVC's. In this paper we have built up a productive strategy to procure the clinical and ECG information, in order to group the information in unsupervised way utilizing k-means clustering technique to precisely analyze the heart and anticipate irregularities assuming any. The general procedure can be ordered into three stages. At last we utilize these two information's i.e. ECG and clinical information for grouping by k-means approach for ordering the coronary illness and to anticipate variations from the norm in the heart or it's working by contrasting the class and the real class. We at that point locate the most imperative highlights of the dataset utilizing molecule swarm enhancement and bolster vector machines coupled together and after that apply a similar calculation on the decreased dataset. We can look at the outcomes acquired from the original dataset with the reduced dataset.

Aproximación teórica del objeto de estudio del turismo
Authors: Fuentes Moreno Aníbal
Published: September 2019

La construcción del conocimiento del turismo ha sido tema básico de diversos investigadores que se reconocen como pioneros de la teoría del turismo, tales como Morgensten, Erenspergel, Glücksmann, Borman, Troisi, Guyer-Freuler, Stradner, además de los connotados turismólogos Hunzinker y Krapf. Dichos autores propusieron, hacia 1942, la Doctrina General del Turismo (DGT) bajo un enfoque disciplinar económico y sociológico, que enfatizó que los visitantes en los 50 eran motivados por su amor al patrimonio cultural especialmente en Europa. Gran parte de los estudios en los 50 y 60 se limitaron al análisis de la demanda y sus variables en gustos, preferencias de compra y diversión, fortalecidospor un creciente interés en las técnicas de promoción, publicidad y comercialización, lo que sería el nacimiento del mercadeo (marketing). Contemporáneos como Luis Fernández Fuster, Manuel Ortuño Martínez, Manuel Ramírez Blanco o bien Oscar de la Torre Padilla, entre otros, han influido en hacer notar que el turismo posee una ciencia que se origina por la teoría desarrollada respecto a este fenómeno y a su práctica. En los 80 Fernández Fuster iniciaría una publicación preguntándose: ¿Es el turismo una ciencia?, provocando no pocas discrepancias que, para aquel tiempo, en donde las ciencias iniciaban su especialización y perfeccionamiento, el planteamiento de la pregunta, se convertiría en un problema de prestigio, agregando que tal fenómeno tiene hasta hoy día, un sinnúmero de conocimientos con entidadpropia, suficiente para que pueda reclamar la categoría de disciplina científica. Sin embargo, las discusiones académicas en el siglo XXI sobre si el turismo es una ciencia o no, están a la orden del día entre los investigadores, académicos, pedagogos y organismos públicos y privados. En este sentido, la pregunta ¿Es el turismo una ciencia?, se vuelve viral en procesos de rediseños curriculares que apuntan a un cambio de matriz productiva en el Ecuador.
Influencia de la aptitud natural de uso del suelo en la pobreza y desnutrición de la población rural en la provincia de Cotopaxi, Sierra Centro del Ecuador

Se tomó como antecedente la preponderancia sistémica de la pobreza de la población rural sobre la urbana, avalada por las estadísticas nacionales y se propuso como objetivo central, determinar la correlación entre la aptitud natural de uso del suelo, incompatible con su uso productivo actual, con la pobreza y desnutrición de la población de las parroquias rurales de la provincia de Cotopaxi; bajo la premisa de que la principal actividad productiva de la población es la agricultura. Se aplicó el modelo de correlación de Spearman, dado que las variables utilizadas no garantizan normalidad para aplicar un modelo lineal; se trabajó con los datos de las 33 parroquias rurales de la provincia, excluyendo a las parroquias urbanas, por sus dinámicas productivas diferentes de la producción primaria. Los resultados revelaron que la pobreza y desnutrición de la población rural están en relación directa con la ocupación de la población en agricultura y el uso incorrecto del suelo, contrapuesto con la aptitud natural de uso. Efectivamente, los mayores niveles de pobreza y desnutrición se concentran en la población de las parroquias cuyos territorios muestran la menor aptitud natural para producir cultivos, pero que al mismo tiempo se ocupan mayoritariamente en la actividad agrícola, (más del 60%, en promedio de la población rural se ocupan de la agricultura). La conclusión principal fue que la actividad de producción primaria en la mayoría del territorio rural de la provincia de Cotopaxi, además de no generar los ingresos suficientes para garantizar una vida digna de las familias, produce una espiral de degradación ambiental en cada ciclo agrícola, que reduce la capacidad productiva de los suelos, con la consecuencia obvia del empobrecimiento sistemático de la población involucrada, amén de su inseguridad alimentaria.
Técnicas de Visión Computacional para determinar el estado fitosanitario en plantaciones de brócoli
Authors: Caina Darwin , Carillo René , Carrillo Marcelo
Published: September 2019

La demanda de brócoli se ha incrementado notablemente en las últimas décadas debido a los benefcios que el consumo de este producto ofrece para la salud humana. Esto plantea nuevos retos para los productores, quienes cada vez más se apoyan en la tecnología para mejorar sus procesos productivos, incrementar los rendimientos y con ello satisfacer la demanda actual. Uno de los campos de la tecnología que ha cobrado interés en la producción agrícola es la aplicación de modelos de Visión Computacional, la cual puede proporcionar soporte y asistencia en la producción de alimentos. En este trabajo se propone un algoritmo basado en la detección de color del brócoli, el cual, a nivel “macro”, sea capaz de identifcar problemas ftosanitarios en plantaciones de brócoli; y, a nivel “micro”, pueda ser empleada para identifcar el producto apto para la comercialización y el consumo. El desarrollo del algoritmo utiliza herramientas de software libre, como OpenCV y Python, lo cual reﬂeja que estas herramientas pueden ser desarrolladas a bajo costo; y que sus resultados son similares o superiores a los obtenidos con softwares comerciales.

Este estudio se realizó con el objetivo de documentar la riqueza y la abundancia de las aves silvestres en nue-ve áreas verdes de Sangolquí. Se registró la avifauna mediante puntos de conteo a partir de las 06h30 hasta las 09h30, en días sin lluvia, desde el 11 de noviembre del 2016 hasta el 18 de febrero del 2017, mediante detección visual y auditiva. Cada uno de los nueve sectores fue muestreado a través de siete puntos de conteo consecutivos. La avifauna registrada incluyó una riqueza de 29 especies con un total de 1.010 individuos re-gistrados. La Tórtola Orejuda Zenaida auriculata fue la más abundante con 292 individuos, mientras que las especies menos abundantes, con un solo registro, fueron el Zorzal de Swainson Catharus ustulatus, Carpintero dorsicarmesi Colaptes rivolii, Gallinazo Negro Coragyps atratus, Pinchaflor Pechicanelo Diglossa sittoides y el Gavilán Alicastaño Parabuteo unicinctus. La Paloma Doméstica, el Gorrión, el Mirlo Grande y Tórtola Orejuda se consideran especies sinantrópicas para Sangolquí. Finalmente, se sugiere restaurar la cobertura arbustiva de las áreas verdes para favorecer la conservación de las aves locales.
