Authors: Kyriachenko Y. , Oskyrko O. , Udovychenko I. , Halenova T.
Published: May 2020

Secretions derived from amphibian skin glands serve as a potential reservoir of various valuable active molecules. Currently, the
multiple substances with diverse therapeutic activities among the components of glandular secretions of different species of
amphibians have been found. It has been proven that they have antibacterial, antifungal, antiprotozoal, antidiabetic, antineoplastic,
analgesic, and sleep-inducing properties. Taking this into consideration, to get the basic knowledge about the properties of the
components of skin secretions of some Anura species that inhabit the territory of Ukraine is crucial for further investigation of the
most potential ones. The red blood cell hemolysis assay is a prevalent test to study the cytotoxicity of studied samples. The aim of
the present study was to analyze the hemolytic activity of skin secretions of Bombina bombina, Bombina variegata, Bufotes viridis,
Rana temporaria, Pelophylax ridibundus, and Pelobates fuscus, and to obtain the primary data on the possible mechanism of their
toxicological action on the blood cells membranes. The skin secretions of six amphibian species mentioned above were incubated
with erythrocyte suspension in different concentrations. Eminently active B.variegata skin secretions, having the HD HD50 value at
0.5 µg/ml, were taken for the subsequent researches, where the effects of osmotic protectants, divalent cations, antioxidants,
chelating agent, and serine protease inhibitor on the cell lysis ability of B. variegata skin secretions was studied. All studied cations
inhibited the hemolytic activity of B. variegata secretions in a dose-depend manner. While the serine protease inhibitor,
phenylmethylsulfonyl fluoride (PMSF), markedly decreased the hemolytic activity of studied skin secretions. We can assume that the
bioactive peptides in these skin secretions have an enzymatic mechanism of action.

Günümüzde yetkinlik geliştirme, kariyer tatmini, iş performansı ile algılanan istihdam edilebilirlik kavramları, örgütsel davranış literatüründe önemli kavramlar arasındadır. Söz konusu kavramlar ve bu kavramlar arasındaki ilişkilerin bilinmesi, işletmelerde her kademedeki yöneticilere ve çalışanlara hem örgütsel hem de bireysel gelişimin nasıl olması gerektiği ile ilgili konularda yol gösterir. Bu kavramlar arasındaki ilişkilerin incelenmesi önem arz etmektedir ve literatürde yapılan inceleme neticesinde, söz konusu kavramlar arasındaki ilişkilerde aracılık etkisinin incelendiği herhangi bir çalışmanın yapılmadığı tespit edilmiştir. Bu kapsamda yapılan çalışmanın amacı, yetkinlik geliştirmenin kariyer tatmini ve iş performansına etkisini ve bu ilişkide aracılık rolünün olabileceği değerlendirilen bireylerin algılanan istihdam edilebilirliğin aracılık etkisinin olup olmadığını araştırmaktır. Bu çalışmada kolayda örneklem ve anket yöntemleri kullanılmıştır. Veriler, 6 adedi devlet ve 3 adedi vakıf olmak üzere toplam 9 üniversitede çalışan 178 öğretim görevlisi ve memurdan toplanmıştır. Anket sonucunda toplanan verilerin analizinde R programlama dili kullanılmıştır. Ölçeklerin geçerlilik ve güvenilirliği faktör analizi ve güvenirlik testi ile test edilmiştir. Kurulan hipotezler korelasyon ve regresyon analizleri ve Sobel testleri ile incelenmiş ve çalışmanın sonunda elde edilen bulgular yorumlanmıştır. Yapılan çalışmanın sonunda, yetkinlik geliştirmenin iş performansının artmasında önemli olduğu, ancak kariyer tatminin artmasında ise etkili olmadığı tespit edilmiştir. Ayrıca, algılanan istihdam edilebilirliğin yetkinlik geliştirme ile kariyer tatmini arasındaki ilişkide aracılık rolünün olmadığı ve yetkinlik geliştirme ile iş performansı arasındaki ilişkide ise kısmi aracılık rolünün olduğu sonucuna ulaşılmıştır.

Published: May 2020

Breast cancer is one of the most common cancer types especially met in women. The number of breast cancer patients increases every year. Thus, to detect breast cancer at its early stages gains importance. Breast region detection is the pioneering step of breast cancer diagnosis researches performed via image processing techniques. The performance of computer-aided breast cancer diagnosis systems can be improved by exactly determining the breast region of interest. In this study, the goal is to determine a region of interest for breast MR images, in which one or more lesion can appear. The achieved region includes two breasts and lymph nodes. The proposed region of interest detection system is fully automatic and it utilizes several image processing techniques. At first, the local adaptive thresholding technique is applied to the noise-filtered grey level breast magnetic resonance images taken with ethical permissions from Sakarya Education and Research Hospital. After adaptive thresholding, connected component analysis is performed to exclude extra structures around the breast region as thorax area. This analysis selects the largest area in the binary image which corresponds to a gyrate region including breast area and lymph nodes over the backbone. Then, the integral of horizontal projection is calculated to determine an optimum horizontal line that allows setting the region of interest apart. In the following step, sternum midpoint is detected to separate the right breast from the left one. Finally, a masking operation is applied to get corresponding right and left breast regions in the original MR image. To evaluate the performance of the proposed study, the results of automatic region of interest detection system are compared with the manual region of interest selection performed by an expert radiologist. Dice similarity coefficient and Jaccard coefficient are used as performance criteria. According to the results, the proposed system can detect region of interest for computer-aided breast cancer diagnosis researches, exactly.

Cambios en el peril proteómico de preadipocitos con diferentes condiciones metabólicas
Authors: Moreno Castellanos Natalia R
Published: May 2020

Introducción y objetivos: El tejido adiposo subcutáneo se considera un depósito con un papel protector desde un punto de vista metabólico. El exceso de tejido adiposo desencadena en obesidad, la cual, está acompañada típicamente por resistencia a insulina, dislipidemia, e hipertensión arterial. No obstante, se conoce que existe un subgrupo de obesos que parecen estar protegidos de dichas complicaciones. Estos individuos son definidos como obesos sanos metabólicamente. A pesar de los avances en el conocimiento de las alteraciones que suceden en el tejido adiposo en obesidad, aún se desconocen los mecanismos que subyacen en el desarrollo de resistencia a insulina. Por lo tanto, en este trabajo, se estudió la asociación entre obesidad y desarrollo de enfermedad metabólica identificando factores y procesos que determinan la transición desde el fenotipo obeso sano y no sano, empleando preadipocitos provenientes de tejido adiposo subcutáneo. Metodología:Se emplearon datos de un estudio de proteómica comparada de preadipocitos de tejido subcutáneo obtenidos de pacientes obesos normoglucémicos no resistentes a insulina y de pacientes obesos con diabetes mellitus de tipo 2. El estudio proteómico, se llevó a cabo utilizando la técnica de iTRAQ combinada con LC-MSMS. Resultados y conclusiones: Las diferencias entre preadipocitos de tejido adiposo subcutáneo en sujetos normoglucémicos y con diabetes, afectan sobre todo a proteínas citosólicas y, en particular, a proteínas relacionadas con procesos metabólicos mientras que, las membranales no cambian entre fenotipos obesos. En el estudio se identificaron importantes diferencias en el perfil proteómico de los preadipocitos de tejido adiposo subcutáneo en obesidad, tanto en sujetos normoglucémicos como diabéticos, apoyando la importancia de estas células en el mantenimiento de la identidad del depósito graso. También se encontró que, la transición desde el fenotipo obeso sano hacia el no sano conlleva un mayor desarrollo de estrés oxidativo e inflamación en las células precursoras adipocitarias
Occupational injuries and the “student syndrome” (or procrastination) on a large construction project
Authors: Niño-Espejo Fredy E , Idrovo Alvaro J
Published: May 2020

Introduction: There is a higher occurrence of injuries on the first working days of the week, and between 13:00 and 17:00 hours. An association between some special dates and changes in the occurrence of deaths or diseases have been described in different countries and regions. Our hypothesis was that completing contractual obligations with a company may become triggers that increase the occurrence of occupational injuries. Methods: Injury records were analyzed and consolidated monthly payroll reports (from January 2012 to September 2013) for personnel operations who worked in companies that were involved in a megaproject to build a road in Colombia. This analysis reports a possible association between dates of financially important contractual milestones and a higher occurrence of occupational injuries. One-tailed binomial tests were used to compare the occurrence of injuries one and two months before and one month after four deadlines, corresponding to 14, 3, 1 and 1% of the overall budget, respectively. Results: The highest occurrence of injuries was observed during the month before the deadline corresponding to 14% of the budget (p=0.07). Discussion: Contractual milestones could act as distal determinant whereas human errors are proximal determinants of injuries.
Association Between Polymorphisms in Cytokine Gene and Viral Infections in Renal and Liver Transplant Recipients: A Systematic Review
Authors: Sakharkar Prashant , Deb Subrata , Mashayekhi Nina
Published: May 2020

Purpose: Although transplantations are associated with an increased risk of post-transplantation infections, they greatly improve life expectancy and patients’ quality of life. Cytokine genes play an important role in the success of transplants due to their immunological functions. A systematic review was conducted to evaluate cytokine gene polymorphisms and risk of cytomegalovirus (CMV), hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in kidney and liver transplant recipients. Methods: A systematic search was conducted using PubMed, EMBASE, Medline and Google Scholar from their inception until January 28, 2019 using appropriate key words. Review articles, case reports or series, studies conducted on non-human subjects and published in languages other than English were excluded. Data were abstracted using a standardized form. The quality of the studies included was assessed using “Risk of Bias Assessment tool for Non-randomized Studies (RoBANS)”. Results: Thirty-one studies met our inclusion criteria; populations studied were diverse with a sample ranging from 20 to 1,671. Nineteen studies evaluated Interleukin (IL)-28B polymorphism, while six studies evaluated interferon lambda (IFN-λ) gene polymorphisms and their impact on CMV, HCV, and HBV progression. Polymorphisms in IL-10 gene were investigated in six studies. Polymorphisms in IL-12B and IL-1B gene were associated with a higher risk of developing CMV infections while polymorphisms in IL-28B were associated with a lower incidence of CMV infection in renal transplant recipients. Similarly, polymorphisms in IL-28B were associated with higher liver dysfunction from HBV infection in liver transplant recipients. Studies included had low risk of bias. Conclusions: Cytokine gene polymorphisms IL-12B and IL-1B were found to be associated with an increased risk of infection in kidney transplants and IL-28B in liver transplant recipients. However, the small number and heterogeneity of studies limits the generalization of our results. Further research may lead to finding these associations in larger studies which perhaps improve the use of genetic testing and targeted antiviral therapy. This will further reduce the risk of viral infections associated with cytokine gene polymorphisms in post renal and liver transplant recipients.

The Effect of the Activator/Precursor Ratio on the Rheological Properties of the Alkali-activated Mining Waste Mud Paste
Authors: Benhamouda Abdelhakim , Castro-Gomes João , Pereira-de-Oliveira Luiz
Published: May 2020

To determine the properties of paste, mortar or concrete, it is necessary to understand its rheological behaviour first. This study discusses the effect of the activator/precursor ratio on the rheological properties of the alkali-activated paste. The pastes consisted of a mix of 70 % of tungsten mining waste mud, 15% waste glass and 15% of metakaolin. This mix was activated by combining sodium hydroxide and sodium silicate. Five activator/precursor (a/p) ratios were studied: 0.37, 0.38, 0.39, 0.40 and 0.41. The result obtained shows that the rheology of the pastes is affected by the activator/precursor ratio. The rheological behaviour of the paste fits the Bingham model. The yield stress (τ0) and plastic viscosity (μ) increase inversely with the activator/precursor ratio (e.g. a/p=0.37 gives τ0=84.19 and μ=0.4185; a/p=0.41 gives τ0=30.389 and μ=0.2937). The workability increases proportionally with the activator/precursor ratio (e.g. a/p=0.37 gives a slump=133 mm; a/p=0.41 gives a slump=158 mm). The compressive strength decreases when the activator/precursor ratio increases (e.g. at 28 days for a/p=0.37, the compressive strength was 19.6 MPa; for a/p=0.41, the compressive strength was 13 MPa). Finally, the ideal ratios were 0.38 and 0.39.
Elaboration of Geotechnical Thematic Maps in Urban Areas
Authors: Monteiro António , Pais Luís , Rodrigues Carlos
Published: May 2020

In urban areas it is difficult to access natural terrain due to strong human intervention. Therefore, any exposure of the natural terrain is considered an important source of geological and geotechnical data collection. The Geographic Information Systems (GIS) has been responsible to provide great development in geotechnical cartography, particularly in urban environment, using geographic databases and new analysis tools. Our goal is to create a geographical database that will allow and/or improve the elaboration of geotechnical thematic maps, using cartographic data of open platforms combined with free and open source GIS software. In the presented study our focus was related with the identification of the granite alteration degree...Through the geographical database, along with the geological map of the study area, the areas related to the degree of granite alteration were identified and delimited. The data were collected through  “Street  View”  which results from the integration of a specific module in the GIS software (QGIS). The obtained data were validated by direct observation and were photographically recorded. This approach proved to be an effective method, with no significant differences when compared with direct observations. The methods’ limitations are the quality of some “Street View” images, and the existent subjectivity related to the observer in the identification of the degree of alteration of the rocky massif. Its advantage is to reduce the data collection’s time and the possibility of comparing the same place at different time points.

Analysis of the Implementation of the Standard Performance ABNT NBR 15.575/2013: A Case Study with Brazilian Constructors
Authors: Silva Moreira Fernanda , Fujita Lima Rafaela , Felipe Cândido Luis , Carlos Gonçalves Lanzinha João
Published: May 2020

The development of studies about the housing constructions developments came from the need to ratify the effectiveness of the construction systems to the detriment of the low quality of the final product related to civil construction, which was unfolded in the creation of ABNT NBR 15,575 / 2013 - Housing Constructions - Performance. However, its implementation is still a point of discussion among several companies in this field, besides there is a gap between the requirements and established criteria and the adequacy of the constructive practices. Thus, the present work aims to analyse, through a multiple case study, the process of implementation of the Standard Performance in Brazilian construction companies, focusing on the main difficulties of implementation. For that, semi-structured interviews were carried out in 5 constructors, being possible to identify the implementation process adopted by each company and its main difficulties of adequacy to the norm. Thus, it was possible to verify that although the standard performance is required, the increase in costs resulting from this requirement has delayed its implementation, being the main difficulty of adequacy. In addition, it was observed that although the implementation process of the regulations is incipient, any effort in its direction represents an improvement in the quality of the civil construction and, consequently, in the durability and useful life of the buildings.
Stress-strain Relationship in Homogeneous and Two-layered Triaxial Test Specimens
Authors: Oliveira Gabriel , Falorca Isabel
Published: May 2020

The stress-strain relationship of a homogeneous specimen, obtained from triaxial compression test, allows to determine stiffness parameters for numerical-method based analyses in common geotechnical software. Stiffness parameters are defined as the ratio of stress to strain along an axis. However, when a heterogeneous specimen is tested, the equivalent elastic modulus that represents a simplification of the nonlinear behavior is complex. This paper presents a study intended to contribute to the debate about the degree to which conventional soil mechanics approaches can be applied to layered specimens. Triaxial compression tests were carried out on both homogeneous and two-layered specimens under a low effective confining pressure of 30 kPa. The triaxial apparatus was chosen since the applied stress and specimen boundary conditions are well defined, and the repeatability of the test method is good. The behavior of both specimens was studied in terms of the stress-strain relationship and stiffness. The main differences were crucial to understanding the composite soil-aggregate interaction, which is discussed and compared. The results indicate that the interface between composite soil and aggregate is important to keep the stability of the layer of aggregate over the soft composite soil, and practical methods of achieving that are suggested.
Proposal of Methodology for Technical Inspection and Rehabilitation Intervention for Multi-family Building of the 60’s in Portugal
Authors: Marcelino Inês , Lanzinha João
Published: May 2020

The rehabilitation of old buildings has been increasing over the last few years due to the lack of maintenance and there is an advanced degradation of the Portuguese built park. This sector of the civil construction has as objective the full reutilization of the existing buildings maintaining its identity. Since Portugal has a large percentage of buildings where it is possible to identify constructive times that accompanied the implementation of different trends and technological evolutions, defining differentiated strategies for intervention. The 1960s deserve some prominence in Portugal because it is composed of a significant set of buildings with reticulated structure in reinforced concrete and without concerns from the point of view of thermal behaviour, which are now inhabited mainly by elderly people, often residing alone. The following work aims to present a methodology proposal and apply it to a case study. The proposed methodology includes the detailed inspection of a building from the 60s in Covilhã, the consultation of residents and the definition of intervention proposals based on the main nonconformities detected. In the first stage, a detailed analysis of the existing situation is proposed, which includes a technical inspection report on the common parts and the different fractions of the building and a survey of residents in order to know their opinions and expectations regarding the work to be carried out. In the second phase we propose a set of measurements, the realization thermograms and the thermal analysis of the different habitable fractions of the building based on the current thermal regulation. After analysing all the data collected, the intervention proposals are defined according to the needs of the building and the residents, in a phased way and with the aim of creating better accessibility, comfort and use conditions.
Making Cycling Spaces in Hilly Cities
Authors: Matias Isabel , Santos Bertha , Virtudes Ana
Published: May 2020

Traffic congestion and environmental pollution in cities have stimulated the rise of policies to encourage practices of less polluting, and more economic and healthier modes of transportation, such as cycling. Several factors influence bicycle use, including the steep gradients which can limit it use, but do not completely prevent it. In this context, urban planning and transport engineering play a key role in promoting cycling, with particular emphasis on the definition and design of cycling networks at hilly cities, according to the citizens’ needs on their daily commutes. To address this challenge, this paper describes the starting developments and the methodological approach of a doctoral research having the following goals: to define the data to be considered in feasibility studies of designing cycling mode in hilly cities; to develop a bicycle suitability model based on demographic, travel-generating poles, type of bicycles (regular vs. electric) and road network criteria; to develop a model to support the definition of cycling network based on connectivity, network intersections, integration with other modes of transportation, parking and safety; and to define a procedure for assessing solutions and define cycling routes hierarchy, having as case study the hilly city of Covilhã, at Serra da Estrela mountain.

Published: May 2020

This paper presents contributions on underground hydric and geothermal resources of the Meda Municipality land. After a brief introduction about the importance of the theme, the Meda municipality’s administrative, geographic, geomorphological and geological frameworks are presented in a synthetic way. The main hydrogeological units of the municipality are presented below and, based on the water surpluses resulting from precipitation, the order of magnitude of the water reserves of those hydrogeological units is advanced. From a vast field survey of groundwater points on the various hydrogeological units, the results obtained from the expeditious physicalchemical parameters are presented, and based on them some waters were selected to carry out complete physical-chemical and some isotopes analyses. Based on all the results, the municipality was organised in three different major hydrogeological domains (Longroiva, Areola, and Graben), for which the conceptual geohydraulic model was developed. From the several results, it is emphasized in particular that in the various domains there are potential to explore special groundwater with characteristics not only for medical spa and aqua-ludic spaces, but also for the production of energy and even not only heat energy, with cascading uses, but also for the production of electricity from groundwater from 70 to 113∘C.

Published: May 2020

Purpose of the study: This study aims to measure the readability of Second Grade Arabic Language books in the United Arab Emirates (UAE).

Methodology: This paper discusses a quantitative survey conducted, based on previous studies which include Momni and Momni (2011), Nasser and Ibrahimi (2013) and Lami and Zoaeni (2014), to examine readability problems in Arabic language books used in UAE schools. The researchers developed a Cloze Test and performed the test on a randomly selected sample of 387 Second Grade students. Both descriptive and inferential statistics (T-Test, ANOVA) were analysed using SPSS version 22 and to examine the readability of Second Grade Arabic Language books.

Main Findings: The result indicates that the students’ average score in all the readability levels to the total score of the Cloze Test is at an unsatisfactory level. There are significant differences in the level of the poetic and prose texts’ readability among the genders and different academic averages.

Applications of this study: This study provides evidence that the long-term goal of the Abu Dhabi Educational Council (ADEC) has yet to be achieved. The outcomes suggest that there is a need to improve students' readability of Arabic Language books in the UAE, starting from the Second Grade.

Novelty/Originality of this study: Readability of Arabic Language Book was widely explained by other researchers, but there is no study conducted on Second Grade students in UAE.
The Evaluation of Syngas Loss from Disposable Syringe Sampling System: A Case Study
Authors: NAGY Gábor , AMBRUS Mária
Published: May 2020

The main advantage of standard gas
sampling methods is their capability to keep a consistent gas composition from
sampling till analysis. On the other hand, the disadvantages include the price
and possible fragility of the sampling equipment, and the speed of sampling.
Thus, a new tool was required that should have low cost, could be used for fast
sampling and during fieldwork. Disposable plastic syringes fulfil all these
requirements with the additional advantage that they can be used multiple times
to take gas samples. With the utilisation of 3-way stopcocks, a filter media
and a butterfly needle, a simple but efficient sampling system was prepared.
Even though the holding time of certain components is not as high as it is for
a standard sample holder, the precise analysis of the gas samples is possible.
Syringes have been successfully utilised in the field of applied pyrolysis, for
small and pilot scale experiments, and can even be used in industrial
environment.

OBJETIVO: Evaluar el impacto de un modelo de Mejoramiento Continuo de la Atención Prenatal sobre la morbilidad materna y la morbimortalidad Perinatal.DISEÑO: Estudio prospectivo descriptivo.MATERIALES Y METODOS: Entre Enero de 1997 y Mayo de 1998, se evaluó la calidad de la atención ofrecida a las pacientes que asistieron a control prenatal en el Centro de Atención Ambulatoria del Instituto de Seguros Sociales (CAA - ISS) y el Centro de Salud Suroccidente del Servicio de Salud del Cauca (CSS -SS) de la ciudad de Popayán. Después de un período de observación de cinco meses, la intervención, realizada en los doce meses siguientes, consistió en la aplicación de un modelo de control de calidad, utilizando un formato diseñado para evaluar el correcto diligenciamiento de 92 variables de la Historia Clínica Perinatal, que permitía además la supervisión y la asesoría continua del personal que realizaba el control. Se analizó el diligenciamiento de 22.292 variables que correspondieron a una muestra del 5.7% de los controles prenatales realizados en ambas Instituciones. El impacto de la intervención se evaluó en los resultados de 1.217 eventos obstétricos ocurridos durante el período del estudio.RESULTADOS: El diligenciamiento correcto de todas las variables se logró incrementar de un 65% a un 92.2% en el CAA - ISS y del 84.5% al 90.8% en el CSS - SS. El mayor impacto de la intervención se evidenció en las tasas de mortalidad perinatal que disminuyeron de 24.3 a 13.0 en el CAA - ISS y de 12.7 a 0 en el CSS - SS, con coeficientes de correlación lineal estadísticamente significativos especialmente en el Seguro Social.CONCLUSIONES: El buen diligenciamiento de la historia clínica, la aplicación de un instrumento de control de calidad y la supervisión conducen al mejoramiento de los resultados perinatales.

The study investigated the difficulties encountered by Grade 11 teachers in teaching Senior High School General Mathematics, the reasons for the problems, and the strategies employed by teachers in overcoming the challenges with an end view of developing training design. The sequential explanatory mixed methods design was used in the study with the aid of a questionnaire checklist and an interview to validate the answers generated by the questionnaires. The study revealed that the challenges in teaching emerged due to time constraints and mastery issues of contents. Though teachers were pedagogically and technologically equipped to teach the course, however, some have poor time management and link to peers to share the best strategies to cope with the problems. Hence, training, as well as seminars and workshops for the unmastered competencies/contents and the competencies with no strategies applied to deal with the difficulties in teaching, are to be provided to Grade 11 General Mathematics teachers by implementing the training design developed by the researchers.

A study on the effectiveness of a teaching based on socio-scientific issues in the training of pre-service teachers
Authors: Cayci Baris
Published: May 2020

In this study, two different learning approaches (the Toulmin model of argumentation and whole class discussion technique) to the training of primary school teachers in Turkey were tested over socio-scientific issues. On the one hand, we identified how prospective teachers experienced a change of mind on these issues before and after the training, and on the other hand, we analysed the changes on their argumentation and attitudes. In this research model, the distribution of participants is in 53 experimental groups and 52 control groups, and the group equivalence transactions are done. The study was used three different measurement tools, such as attitudes towards socio-scientific Issues Scale, argumentation test and the Teacher Efficacy Scale. The study included teaching processes based on socio-scientific issues (SSI) for 5 weeks each. Furthermore, the indecisiveness participants displayed in socio-scientific issues completely disappeared in the teaching group following the Toulmin model, and each member of this group made a definite decision on the issues covered.

Keywords: Socio-scientific issues, teacher candidates, argumentation model.

Authors: Madarova Slavka , Garcia Laborda Jesus
Published: May 2020

Foreign language bilingual education has been common in many countries all over the world for many years after the Quebec issue in the 1970s. However, after all these years, bilingual education still remains as a criticized way of education. This research essay examined the most significant criticism by summarizing it into seven common misconceptions of the bilingual education schooling system in Spain in general education English-Spanish 1stâ€”12th grade. A lot of criticism has been directed towards the differences between regular mainstream classes and bilingual classes especially in Primary education. This paper looks at seven commonly addressed issues. The paper especially focuses on Primary education but most revision matters also relate to secondary and even higher education. Special interest is paid to cognitive, social, economic, mode of bilingual education, role of the immigrant students and parentsâ€™ attitudes. The conclusion leads to the understanding that English-Spanish bilingual education is not pernicious but, on the contrary, benefits the cognitive a linguistic development of most school children.

Frontal lob sendromu, genellikle travmatik ya da neoplastik bir frontal lob hasarı sonucu görülen kişilik değişikliği tablosudur. Lezyonun lokalizasyonu orbitomedial bölgede ise amnezi ve konfabulasyon (masallama), disinhibe kişilik değişiklikleri çocuk-suluk, şakacı eğilim, seksüel dishinhibisyon, saldırganlık yelpazesinde bir kliniğe neden olur. Dorsolateral lezyonlar ise kararsızlık, apati ve yürütücü işlevlerin zayıfladığı bir tabloya yol açabilmektedir. Frontal lob sendromuna en sık yol açan neden, travmalar ve tümörler olup, serebrovasküler olaylar, nörodejeneratif hastalıklar, santral sinir sistemi enfeksiyonları ve bazı başka hastalıklarda da bu tablo görülebilmektedir. Hastanın kişiliğindeki dramatik değişiklikler, frontal lob sendromunu dikkat çekici kılmakta, bu olgular, travma kökenliler çoğunlukta olmak üzere çeşitli davalarda adli tıbbi değerlendirmeye konu olabilmektedirler. Bu vakaların değerlendirildiği raporlarda söz konusu tablonun anatomik ve psikiyatrik komponentleri detayları ile irdelenmeli, dava dosyası da beraberinde incelenmek suretiyle görüş sunulmalıdır.
Procesos de educación intercultural y autosegregación indígena en los Aimaras de Puno, Perú
Authors: Bermejo Paredes Saul , Maquera Maquera Yanet Amanda , Bermejo Gonzáles Luz Yohana
Published: May 2020

El objetivo del estudio es interpretar desde la racionalidad aimara, cómo los procesos de educación intercultural bilingüe (EIB) desarrollados en las escuelas rurales de la zona aimara de Puno-Perú, generan como resultado después de cuarenta años, el fenómeno de la autosegregación indígena.  Originalidad: la autosegregación no se encuentra explicitada como meta u objetivo por ninguna política o programa EIB; es una temática nueva y vinculante para redefinir, la educación impartida en las poblaciones indígenas.  Método: es un trabajo de investigación cualitativa-hermenéutica que, empleando las estrategias del análisis documental y las entrevistas en profundidad; interpreta los resultados, mediante el proceso de análisis de contenido, fundamentalmente, permitiendo establecer como conclusión que, la EIB desde la racionalidad aimara cobra solamente un valor simbólico, se percibe como un programa racista, que a través del tiempo ha provocado, un paulatino desplazamiento lingüístico del aimara por el castellano y la folclorización de la sabiduría y la cultura aimara; situación que simultáneamente, ha posibilitado la emergencia de la autosegregación indígena, como estrategia y racionalidad para redefinir la EIB, la educación en general y la subsistencia de la nación aimara.
La Educación Intercultural en la Guatemala del siglo XXI: una crítica desde la Historia
Authors: Véliz Catalán Néstor Felícito
Published: May 2020

Objetivo: Este artículo plantea un análisis crítico del desarrollo de los procesos de educación intercultural en Guatemala confrontando los supuestos operativos de la misma a nivel internacional y la praxis sometida a las condiciones locales.  Método: Utilizando un enfoque crítico y comparativo, se busca comprender el porqué, las prácticas educativas en cuestión se orientan circularmente, enfocándose en la conservación de las culturas originarias en lugar de propiciar las capacidades para interactuar con otras.  Estrategias: Un análisis de los discursos oficiales y textos analíticos, ha permitido establecer que, el carácter presentado por la educación intercultural guatemalteca obedece, en la actualidad, a la sustitución de la educación tradicional, asimilacionista y absorbente, la que se plantea modificada con la vigencia de los Acuerdos de Paz firmados en 1996.  Originalidad: El artículo aporta un balance crítico sobre los resultados del enfoque oficial sobre la educación intercultural, un aspecto inédito en Guatemala.  Se puede concluir que la forma en que se desarrolla esta modalidad educativa obedece a un enfoque institucional que la asume como la solución de los problemas educativos de los pueblos indígenas a partir del incentivo al uso de las lenguas nativas en los espacios escolares y el rescate de rasgos culturales identitarios.
Dinámicas escolares asociadas a la construcción de un currículo intercultural para la paz y la justicia territorial en el Caribe colombiano, 2018-2019
Authors: González Monroy Luis Alfredo , Ortiz Segrera Jennyfer Tatiana , Gamarra Rosado Luis David
Published: May 2020

Objetivo: El artículo esboza una comprensión en torno a la elaboración de un currículo intercultural para comunidades educativas donde sus miembros han sido victimas del conflicto armado colombiano. Método: Generando un diálogo de saberes y conocimientos entre investigadores y participantes, en un ejercicio de formación recíproca que llevó a reivindicar la tradición oral, que ha sido subalternizada por los discursos escolares del orden transnacional. Estrategias:El horizonte teleológico se trazó en la concepción de hacer una intervención cooperativa, en la cual participó una universidad y una escuela pública rural con el fin de empoderar categorías como interculturalidad, paz y justicia territorial en sus miembros. Esta sinergia incentivó a la comunidad para dar un salto adelante en su nivel de conciencia de práctica docente frente al “otro”. Originalidad: Esta comunicación académica sustenta la elaboración de nuevo conocimiento a partir de las voces de los participantes in situ. Conclusión: La rutina investigativa de injerencia se asume como una herramienta crítica para el cambio social, especialmente, cuando dentro de sus marcos generales los maestros aprenden a innovar y mejorar las realidades propias de una cultura o comunidad, en la expectativa de reconstruir experiencias de aprendizaje que pueden ser propuestas a partir del diseño, implementación y evaluación de acciones pedagógicas para la diversidad.
