Uma nova abordagem bíblico-arqueológica do contexto histórico do livro de Neemias
Authors: Kaefer José Ademar , Xavier Suely
Published: January 2020

O presente artigo apresenta uma análise do contexto histórico do livro de Neemias à luz das recentes descobertas e conclusões da nova arqueologia. Pela análise literária se percebe uma incongruência quanto à cronologia dos fatos históricos narrados nos livros de Neemias e Esdras, o que dificulta precisar a data da composição de ambos. Concomitantemente, a arqueologia revela que existe um grande vazio no que tange a evidências arqueológicas do período persa. Os resultados das escavações em Jerusalém e arredores colocam uma grande interrogação quanto ao tamanho da Província Jehud, ao tamanho da cidade, à importância do templo, enquanto centro da coleta de tributos, à existência da muralha persa, à existência neste período das localidades mencionadas no texto etc. A ausência de evidências arqueológicas parece apontar ainda para um grande declínio da escrita em Judá durante o reinado persa. Toda esta situação deveria colocar a comunidade acadêmica em alerta, uma vez que a pesquisa moderna tende a situar grande parte da produção bíblica no período persa.
Renascimento e reforma: interfaces sociais e epistemológicas
Authors: Damião Abraão Pustrelo
Published: January 2020

Este trabalho constitui-se de uma análise bibliográfica acerca da história das ideias e das práticas epistemológicas que possibilitaram, em conjunto, o surgimento e a legitimação da Reforma Protestante durante o Renascimento. Para tanto, apresenta as principais características do Humanismo cultural e suas ramificações sociais, no intuito de esclarecer a sociabilidade comum que envolve o pensamento e a atividade dos indivíduos deste período. Isso significa que uma ideia pode surgir a qualquer momento, mas só ganhará força “histórica” se for ao encontro dos interesses de sua época. Neste sentido, o artigo enfatiza que a Reforma só foi possível, porque as condições materiais, intelectuais e psicológicas dos indivíduos, que participaram dela, convergiram em direção a novas ideias e práticas por ela inspiradas.

Introducción: El papel de los profesionales de la salud es crucial para suministrar información sobre vacunación y tranquilizar a las gestantes sobre la seguridad y los beneficios de la inmunización para la madre y los niños. La falta de recomendación del inmunobiológico se puede asociar a las dificultades en la indicación y contraindicación clínica, el manejo de los efectos colaterales y de las reacciones adversas a los inmunobiológicos y por la falta de capacitación del profesional. Adicionalmente, la falta de instrumentos de medición, para el cuidado en la sala de vacunación, justifica la construcción y validación de herramientas para tal fin. Objetivo: Construir y validar el contenido y la apariencia de un instrumento que evalúa el conocimiento de profesionales de la salud sobre la vacunación de gestantes. Materiales y Métodos: estudio metodológico para la elaboración de un instrumento de medición. Se utilizó la Técnica Delphi para validar el contenido y la apariencia de los elementos. Se calculó el Índice de Validación del Contenido (IVC) y el Content Validity Ratio (CVR) para calcular el grado de concordancia entre los jueces. Para obtener la puntuación del instrumento, además de los ítems de evaluación del conocimiento, también se envió a los jueces una escala de criterios de puntuación para evaluar el conocimiento de los profesionales en función de las recomendaciones del Ministerio de la Salud sobre la vacunación del gestante. Resultados: Todos los ítems del instrumento obtuvieron un IVC variable de 90% a 100% y un CVR entre 0,7 y 1,0, confirmando la validez del contenido. Discusión y Conclusiones: El instrumento presentó un índice de validez de contenido satisfactorio y se puede utilizar para evaluar el conocimiento sobre vacunación de la gestante.
Solubility in the Na,Ca||SO4,HCO3-H2O system at 25 °C
Authors: Soliev L. , Jumaev M. T. , Varkaeva A. M. , Makhmadov Kh. R. , Sinoi G.
Published: January 2020

Water solubility at 25 °C was studied in the four-component water-salt system comprised of sodium and calcium sulfates and hydrocarbonates in order to determine the concentration parameters of solution and crystallization of the constituent salts and to experimentally verify the phase equilibria in the geometric images of the system predicted previously by the translation method. The prediction of possible phase equilibria in geometric images of the system, followed by plotting its phase diagram, appreciably decreases the time and material costs of experimentation and improves the reliability of results. Our results can serve both as reference information and as a scientific base for optimizing the parameters of natural and artificial processes, in particular, the recycling of salt from liquid waste of aluminum production facilities.

Published: January 2020

Calcium sulfoaluminate cement (CSA) has the characteristics of rapid hardening, high early strength, high corrosion resistance and high impermeability, but its ability to continue to show strength increases at middle and late ages is poor. In this study, this drawback was improved by clinker mineral design. Alite (C3S) in Portland cement clinker was used as a seed crystal to induce new C3S in CSA clinker. The role of the introduction of C3S and the effect of commonly used CSA admixtures on the setting time and hydration properties of alite-modified CSA (AMCSA) are described in this paper. Due to the hydration characteristics of C3S, it was found that its introduction effectively improved the bond strength of the mortar and the strength growth persistence in middle and late stages. Commonly used CSA admixtures (e.g. lithium carbonate and boric acid) had the same effect on the setting time and hydration properties of the AMCSA mortar. The addition of lithium carbonate accelerated the cement hydration rate and shortened the setting time, which is beneficial for super early strength of mortar and enabled compressive strengths of up to 4·67, 9·10 and 22·49 MPa at 30 min, 1 h and 4 h, respectively. The addition of boric acid retarded the cement setting time due to a reduction in the hydration rate.
A Petri net approach to assess the effects of railway maintenance on track availability
Authors: Fecarotti Claudia , Andrews John
Published: January 2020

The railway infrastructure includes a portfolio of assets that are subjected to degradation and failure processes due to both usage and ageing. As a consequence of degradation and failures, speed restrictions and line closures may be imposed to control the risk of derailment. Such actions have a direct impact on service, as they lead to delays and journey cancellations. Maintenance is implemented to control the state of the assets. Different maintenance strategies determine different asset conditions and performance profiles and, consequently, a different impact on service. This paper presents a simulation tool based on Petri nets, which combines degradation and maintenance processes to predict future track geometry conditions, including the probability of those failure modes leading to speed restrictions and line closures. Such a model is a valuable feature of an effective infrastructure-asset-management system that intends to support cost-effective informed decisions on railway maintenance.
Pull-out behaviour of steel fibres in cracked concrete under wet–dry cycles – deterioration phenomena
Authors: Marcos-Meson Victor , Solgaard Anders , Skovhus Torben Lund , Jakobsen Ulla Hjorth , Edvardsen Carola , Fischer Gregor , Michel Alexander
Published: January 2020

This paper presents an experimental investigation into the mechanisms altering the pull-out behaviour of partially pulled hooked-end steel fibres inside an artificial crack exposed to wet–dry cycles of chlorides and carbon dioxide for 6 months. Mechanical and corrosion damage at the surface of the steel fibre was investigated using three-dimensional optical interferometric profiling, and petrographic analyses were used to describe damage and healing processes at the matrix surrounding the fibre. Mechanical damage observed in the cementitious matrix and at the fibre's surface confirmed that the pull-out process was governed by yielding of the fibre, fracture of the adjacent matrix, and friction between the hook and the matrix. Increases in the pull-out force of partially pulled-out fibres after exposure were connected to accumulation of corrosion products from the steel fibre and to alteration of the cement matrix surrounding the fibre. This study concluded that autogenous healing and carbonation of the damaged cement matrix around the fibre are the main mechanisms responsible for the increase in the fibre–matrix bond strength of hooked-end steel fibres bridging cracks in concrete exposed to wet–dry cycles.
Dichtung und Wahrheit. Gesichtsmasken in der Berliner Gipsformerei
Authors: Tocha Veronika
Published: January 2020

Johann Wolfgang von Goethe (1749-1832) sah etwas "Fremdartiges, ja völlig Unwahres" im Medium der Totenmaske. Überhaupt schien ihm der Tod "ein sehr mittelmäßiger Porträtmaler", weshalb er sich nicht nur gegen die Abnahme seiner eigenen Totenmaske aussprach, sondern es auch ablehnte die Totenmasken seiner Freunde zu betrachten. Mit dieser Haltung nimmt Goethe im Kontext seiner Zeit eine Ausnahmestellung ein, waren Totenmasken von öffentlichen Persönlichkeiten und Geistesgrößen aller Art ab dem frühen 19. Jahrhundert doch höchst populär und wurde die Abformung des Totengesichts gerade deshalb praktiziert, weil sie - so der damalige Konsens - wie kein anderes bildgebendes Verfahren Realitätsnähe und Wahrheit verbürgte.

Published: January 2020

The present work aimed to evaluate the effect of temperature, particle size and bed height of the chromium (VI) adsorption process using plantain peels in a continuous system. The experiment was carried out on a packed bed column, adjusting the feed temperature of the solution with a REX-C100 controller coupled to a type K thermocouple. The initial concentration of Cr (VI) was set at 100 ppm, the pH at 2 and the feed rate of 0.75 mL/s. The analyses were performed by UV-Vis spectroscopy using the colourimetric method of 1.5-diphenylcarbazide. The material was characterized by infrared spectrometry by Fourier Transforms (FTIR), from this analysis, it was determined that the OH and NH2 functional groups are the main responsible for the formation of complexes with the cations in solution. Also, it was established that only the particle size is statistically significant. According to the response surface analysis, the optimum conditions of the process were 353.15 K, a particle size of 0.819 mm and a bed height of 67.768 mm. From the thermodynamic study of the process, it is established that it is endothermic and the chemical adsorption prevails in it. The results obtained in the process modelling suggest that Dose-Response can be used reliably to scale the process.

Authors: Muñoz-Neira Milton Javier , Roa-Ardila Manuel Fernando , Correa-Celi Carlos Rodrigo
Published: January 2020

This article reports a comparative study of experimental results obtained during the drying of Castilla-variety coffee beans from Santander, Colombia. They were performed by two means: thermal and electromagnetic radiation. Twenty experiments were carried out, ten tests in a microwave cavity at 2,450 MHz-1,080W, and ten tests using a conventional electric oven with temperature controlled at 50±2oC. Experiments were made using samples of coffee beans with parchment, without parchment, and of the only-parchment. For each sample, dimensionless moisture ratio and diffusion coefficients were determined, according to the second law of Fick. We found that the diffusion coefficient of the samples dried in a microwave cavity was twenty-two times higher than the diffusion coefficient of samples dried with thermal radiation. Likewise, it was observed that samples in conventional oven showed a uniform temperature, in contrast with those heated by microwave radiation. Such results are useful for designing hybrid systems for drying coffee beans.

Published: January 2020

Bicycle sharing systems are an alternative to promote sustainable transportation and active living. Bicycle users are exposed to traffic and to pollutants in their trips; therefore, the analysis of pollutant concentrations and user exposure is of utmost importance for planning the expansion of creation of these transportation systems. In order to evaluate the concentrations and exposure of cyclists to PM2.5, we designed a route within the bicycle sharing system of Medellin and implemented a sensor-based monitoring protocol. Measurements were carried out with a low-cost sensor validated with local information. Potential average daily dose of PM2.5 was calculated based on the average time of exposure and the level of effort made by the user while riding. Hotspots were identified as the zones on the route with concentrations three standard deviations above the average for each route. PM2.5 concentrations were found to be highly variable in terms of hour of the day and season of the year. When the concentrations are higher, the potential average daily dose is doubled. There are two types of hotspot according to the built environment configuration on the route, and the concentrations in these hotspots are reaching values considered as harmful for sensitive population groups. The present results are key for the discussion leading to the implementation of measures that will improve the welfare of cyclists in Medellin, that may span from infrastructure intervention to early warning systems.
Study of the lateral vibration in a multistage rotor
Authors: Mendivelso-Duarte Carlos Yesid , Arzola de la Peña Nelson , Cruz-Guayacundo Wilmer
Published: January 2020

This paper presents the development of theoretical and experimental models for the study of rotodynamic behavior of a multistage rotor. The transfer matrix method, which includes the characteristics of stiffness and damping for the supports and the stages respectively as well as the characteristics of unbalance in the stages, is used for the theoretical model. The data from a physical model was employed as a way of validating the theoretical results. The first two critical speeds were determined with the theoretical model and they differ in a low percentage with respect to the values measured experimentally. Moreover, the vibration level recorded in the physical model rises 2.5 times when the multistage rotor approaches the first two critical speeds. In addition to this, significant displacements of the lateral critical speeds are noticeable when an increase in mass imbalance is induced in several of the rotor impellers.
Analysis of the Soiling Effect on Solar-Panel Power Efficiency in the Colombian Caribbean Region

Published: January 2020

This paper summarizes the impact of particulate material on solar-panel performance for systems located in the Colombian Caribbean Region. First, the dirt/particles are identified and classified; and then, their effect in the reduction of solar panel efficiency has been estimated at most of 6% during the times of the day with the maximum solar radiation. It has been found that the impact decreases exponentially for other hours during the day, which implies that dirt effect becomes negligible on the electric power available. The study reveals that the effect of dirt/particles is significant from a clean solar panel to one with light accumulation, but rapidly diminishes as accumulation changes from light to heavy. Thus, it is suggested that once some dirt accumulates on the panel, a cleaning procedure can wait until the particle accumulation is heavy without sacrificing efficiency excessively. The results of the study become a tool to estimate the trade-offs between power efficiency of photovoltaic systems and financial viability of those projects. Hence, inverters can be chosen such that they can limit the amount of electric power while minimizing the stochastic nature of solar radiation and the dirt/particle effect. The analysis presented starts through a complete Multivariate Analysis of Variance (ANOVA) considering three fundamental factors: dirt/particles, solar radiation and day.

DISCOURSE SYNERGY IN THE INTERCULTURAL CONTEXT
Authors: Kravchenko N. H.
Published: January 2020

The development of linguistic research in the conditions of globalization acquires a new understanding, since it correlates with culturology, ethnology, and explicates the linguistic and cultural heritage. Modern linguistic intelligence is extrapolated to the problems of intercultural communication, linguistic aesthetics, and the study of national and cultural realities. The consideration of languages, in particular Germanic, in intercultural interaction appears to be actualized, because the knowledge of national values and communication peculiarities of Germanic native speakers contributes to the comprehension of the specific cognition nature of their cultural environment.

Authors: Kim Min Jin , Song Ji-Soo , Kim Young-Jae , Kim Jung-Wook , Jang Ki-Taeg , Hyun Hong-Keun
Published: January 2020

Molar root-incisor malformation (MRIM) or molar-incisor malformation (MIM) is a new type of dental anomaly characterized by dysplastic roots of permanent first molars, occasionally second primary molars, and the crowns of maxillary central incisors. MRIM involving permanent first molars and second primary molars is characterized by normal crowns with short, thin, and narrow roots, whereas MRIM involving permanent maxillary central incisors exhibits constrictions of the crown in the cervical area. In the first case, we extracted the affected first permanent molars at the optimal timing to minimize space deficiencies and induce space closure. In addition, composite resin restorations were performed on the anterior central incisors. In the second case, a mandibular lingual arch was used to stabilize the affected teeth in order to mitigate discomfort by reducing rotational biting forces.

Published: January 2020

Aim: The present study aimed to evaluate the association between parenting styles, child's behavior in dental setting and dental caries status. Study design: Children aged 3–7 years on their first dental visit were included in the study. Their parents were asked to complete Parenting Style Dimension Questionnaire (PSDQ) to assess their parenting style. Oral prophylaxis was performed for the children and their behavior was assessed using Frankl behavior rating scale. Their caries status was recorded using DMFT/deft index. Results: Out of 315 parents, 240 parents exhibited authoritative parenting style, 45 exhibited permissive and 30 exhibited authoritarian parenting style. Permissive parenting was associated with four-fold increase in the child's negative dental behavior and authoritarian parenting showed two-fold increase in the negative behavior of children compared to authoritative parenting. Children of both authoritative and authoritarian parents showed less caries status and the permissive parenting depicted threefold increase in the caries status compared to authoritative parenting. Conclusion: Children of both the permissive and authoritarian parents showed more negative dental behavior than children of authoritative parents. Children of permissive parents showed increased caries status compared to the children of authoritative parents.

Published: January 2020

Objective: Although mitis-salivarius-bacitracin (MSB) agar is a commonly used selective medium for detecting Streptococcus mutans in clinical studies, non-S. mutans microorganisms are cultivatable on MSB agar. Since few studies have identified non-S. mutans bacteria grown on MSB, this study aimed to identify and differentiate MSB-grown non-S. mutans bacteria from predente infants' oral cavity. Study design: The saliva from 51 predente infants were plated on MSB agars. Bacteria colonies were characterized based on their morphology under direct visualization and light microscopic observation. Colony PCR targeting S. mutans htrA locus and 16S rRNA DNA sequencing were used for further bacteria identification. Results: Overall, 80% of the predente infants had oral bacteria grown on the MSB agar. Nine bacteria were identified, including S. mutans, Staphylococcus epidermidis, Klebsiella quasi-pneumoniae, Klebsiella pneumoniae, Enterobacter kobei, Enterococcus faecalis, Staphylococcus hominis, Streptococcus anginosus and Phytobacter. The most frequently detected bacteria were S. epidermidis (41.5%), followed by E. kobei (24.4%), K. pneumoniae (17.1%) and S. mutans (9.8%.) Conclusions: Multiple non-S. mutans bacteria from infants' oral cavity could grow on MSB agar. Caution should be exercised in counting the colony forming units of S. mutans from oral samples on MSB agar to avoid overestimation by assuming that all colonies on the MSB agar are S. mutans. Using the colony morphological guide we summarized, these non-S. mutans bacteria could be distinguished from S. mutans. Our study provides a key reference to pediatric cariology clinical-epidemiological studies that commonly use MSB to identify/quantify S. mutans in infants and young children.
Fecal blood tests-screening methods for identification of pre-tumor changes and tumors at the early stage
Authors: Novikova Valeriya P. , Drygin Alexey N.
Published: January 2020

Mortality due to cancer of the rectal colon is currently increasing in all groups of the adult population. Various screening methods are used to identify the pre-tumor and early stages of the development of tumor pathology of the colon: occult blood tests in feces, computer colonography (virtual colonoscopy), colonoscopy, DNA testing, tumor marker M2-PK (tumor fractional pyruvate kinase fraction M2). All of these colorectal cancer screening methods give good results, but there is no consensus among experts regarding the choice of the most optimal method. One of the first tests to detect hidden blood in the stool was biochemical tests: guaiac test (gFOBT guaiac fecal occult-blood test ), in which hemoglobin in the stool was detected by a biochemical method that exploited the pseudoperoxidase activity of hemoglobin and the Gregersen reaction, which is a benzidine test in which benzidi was used instead of guaiac resin And instead of a hydrogen peroxide barium peroxide. Enzyme-linked immunosorbent assays, in contrast to biochemical ones, use antibodies specific only to human hemoglobin, which excludes false-positive results obtained using the biochemical method. The FIT test (Fecal Immunochemical Test or Immunochemical Fecal occult blood test) specifically determines human hemoglobin in feces at lower threshold values (40300 g HB/1 g feces) compared to g-FOBT. Due to its high accuracy, Enzyme-linked immunosorbent assays are successfully used to detect occult blood in inflammatory bowel diseases, allergic enteropathies, acute intestinal infections, and erosive gastritis.

Earthquake early warning systems (EEWSs) are considered to be one of the most effective means for seismic risk mitigation, in terms of both losses and societal resilience, by releasing an alarm immediately after an earthquake occurs and before strong ground shaking arrives the target sites to be protected. To gain experience for the National System for Fast Seismic Intensity Report and Earthquake Early Warning project, we deployed a hybrid demonstration EEWS in the Sichuan–Yunnan border region with micro-electro-mechanical system-based sensors and broadband seismographs and low-latency data transmission. In this study, we described the structure of this EEWS and analyzed its performance in the first 2 yr from January 2017 to December 2018. During this test period, the EEWS detected and processed a total of 126 ML 3.0+ earthquakes, with excellent epicentral location and magnitude estimation. The average location and magnitude estimation errors for the first alert were 4.2±7.1  km and 0.2±0.31, respectively. For the earthquakes that occurred inside and outside the hybrid network, the first alert was generated 13.4±5.1  s and 26.3±13.5  s after the origin time (OT), respectively. We analyzed the performance of the EEWS for the 31 October 2018 M 5.1 earthquake, because it was the largest event that occurred inside the hybrid network during the test period. The first alert was obtained at 7.5 s after the OT, with a magnitude error of 0.1 magnitude unit, a location error of about 1 km, and a depth error of 8 km. Finally, we discussed the main differences between the EEWS’s estimates and the catalogs obtained by the China Earthquake Network Center, and proposed improvements to reduce the reporting time. This study demonstrated that we constructed a reliable, effective hybrid EEWS for the test region, which can provide sufficient support for the design of the National EEWS project.

Raf ömrü işlenmiş ürünün önceden belirlenmiş mikrobiyel, besinsel, tekstürel, duyusal özellikleri ve tüketici beğenisini koruduğu depolama süresi olarak tanımlanabilir. İşlenmiş gıdalar taze halleri ile kıyaslandığında daha uzun raf ömrüne sahiptir ve bu yüzden standart depolama koşullarında raf ömrü testleri uzun zaman gerektirmektedir. Bu nedenle son yıllarda gıdaların kontrollü ve ağırlaştırılmış depolama koşullarındaki bozunma oranlarının ve kalite parametrelerindeki değişimlerin daha hızlı ve kolay belirlenmesi için hızlandırılmış raf ömrü testleri kullanılmaktadır. Çalışma raf ömrü, hızlandırılmış raf ömrü testleri ve raf ömrü tahmininde kullanılacak reaksiyon kinetiği yaklaşımlı matematiksel modelleri açıklayarak son yıllarda hızlandırılmış raf ömrü testleriyle ilgili seçilmiş çalışmaları özetlemeyi amaçlamaktadır.

Bu araştırmanın amacı, sosyal medya kullanıcılarının sosyal karşılaştırma eğilimlerini incelemektir. Bu çerçevede üniversite öğrencisi sosyal medya kullanıcılarının sosyal karşılaştırma hedeflerinin, karşılaştırma sürecinde yaşadıkları duyguların ve ortaya koydukları davranışların incelenmesi hedeflenmiştir. Temel nitel araştırma yöntemi ile gerçekleştirilen bu araştırmaya katılacak öğrencilerin belirlenmesinde amaçlı örnekleme yöntemlerinden ölçüt örnekleme tekniği kullanılmıştır. Araştırmaya sosyal medya hesabı olan ve yaşları 18-22 aralığında değişen 4’ü kız, 3’ü erkek 7 lisans öğrencisi katılmıştır. Veriler, araştırmacı tarafından yarı yapılandırılmış görüşme formu ile Mart-Nisan 2018 ayları içerisinde toplanmış ve elde edilen verilerin analizinde tümevarımsal analiz yöntemi kullanılmıştır. Yapılan analizlerin inandırıcılığı ise ilgili bir alan uzmanın kontrolü ile sağlanmıştır. Sosyal medya kullanıcılarının sosyal karşılaştırma eğilimlerine ilişkin bulgular araştırmanın amaçları doğrultusunda “karşılaştırma hedefi”, “karşılaştırmalarda ortaya çıkan duygular” ve “karşılaştırmalarda ortaya koyulan davranışlar” şeklinde kategorileştirilmiştir. Bu doğrultuda karşılaştırma hedefine ilişkin elde edilen bulgularda, katılımcıların sosyal medyada çoğunlukla yukarı doğru karşılaştırmalara yöneldiği, aşağı doğru karşılaştırmalara ise daha az başvurduğu görülmektedir. Karşılaştırmalarda ortaya çıkan duygulara bakıldığında ise; katılımcıların yukarı doğru karşılaştırmalarda çoğunlukla umut, imrenme gibi asimilasyon duyguları, daha az ise kıskançlık gibi kontrast duyguları yaşadıkları; aşağı doğru karşılaştırmalarda ise daha çok üzüntü, acıma, korku gibi asimilasyon duyguları, daha az ise küçümseme gibi kontrast duyguları yaşadıkları görülmektedir. Son olarak karşılaştırmalarda ortaya koyulan davranışlar bağlamında katılımcıların yukarı doğru karşılaştırmalarda benliği geliştirici davranışlar sergiledikleri; aşağı doğru karşılaştırmalarda ise kaçınma davranışına başvurdukları görülmektedir. Bu bulgular genel olarak sosyal medya kullanıcılarının sosyal karşılaştırma eğilimlerinin yukarı veya aşağı doğru olabildiğine, buna göre de karşılaştırma sürecinde yaşadıkları duygu ve davranışların değişebileceğine işaret etmektedir.

Açık ve uzaktan öğrenme ortamlarında başarı için gerek şart olarak kabul edilen eylem yeterliği faktörü, öğrenme motivasyonunun önemli bir parçası ve öğrenen başarısının tamamlayıcısı olarak kabul edilmektedir. Bu bakış açısıyla açık ve uzaktan öğrenenlerin eylem yeterliklerinin incelenmesi önem taşımaktadır. Bu bağlamda bu çalışmanın amacı, Anadolu Üniversitesi Açıköğretim Sistemine kayıtlı öğrencilerin eylem yeterlik düzeylerini incelemektir. Çalışma, nicel araştırma yöntemlerinden tarama modelinde gerçekleştirilmiş kesitsel bir araştırmadır. Araştırmada veri toplama aracı olarak Eylem Yeterliği Ölçeği ve kişisel bilgi formu kullanılmıştır. Veriler, çevrimiçi ortamda gönüllülük esasına göre uzaktan öğrenenlerden toplanmıştır. Veri toplama aracına cevap veren 1132 kadın ve 1002 erkek toplam 2115 öğrenen araştırmanın örneklemini oluşturmaktadır. Çalışmanın araştırma sorularına yanıt bulmak amacıyla elde edilen veriler çözümlenirken betimsel istatistikler, bağımsız örneklemler için t-testi ve bağımsız örneklemler için tek faktörlü varyans analizi (ANOVA) kullanılmıştır. Araştırma sonuçları, Açıköğretim sistemine kayıtlı öğrencilerin eylem yeterlik düzeylerinin ölçeğin ortalama puanlarına göre orta seviyenin üstünde olduğunu göstermektedir. Bu bulguya ek olarak, öğrencilerin eylem yeterlik düzeylerinin; cinsiyete, yaşa ve kayıt türüne göre farklılık gösterdiği ancak öğrencilerin Açıköğretim sistemine giriş yılına göre farklılık göstermediği bulunmuştur. Öğrenme motivasyonunun tamamlayıcısı olarak kabul edilen eylem yeterliği, öğrencilerin motivasyon seviyelerinin, derslerde başarılı olma ve okulu tamamlama eğilimlerinin bir göstergesi olarak kabul edilebilir. Ayrıca, eylem yeterliği uzaktan eğitimde öğrencilerin başarılı olup olmama durumlarını yordaması açısından da önemlidir.

The sociocultural approach has recently been focused on teaching thinking skills and considering the rapidly changing information age and lifelong learning skills, it can be said that culture-based thinking instruction has become more popular. The literature illustrates few but various studies regarding the contribution of the culture of thinking in different projects. In that vein, this study seeks to examine English Language Teaching (ELT) Moonlight 8th grade students’ book and workbook which were distributed by the Ministry of National Education and taught in state schools within the context of the culture for thinking. The target textbooks were analyzed through document analysis in the framework of qualitative research designs. Tishman, Perkins, and Jay (1995)’s framework of the culture of thinking was taken as a basis for examining the target textbooks regarding culture of thinking and main themes have been shaped. The findings of the study concluded that along with the activities supporting the culture of thinking in regard to the language of thinking, mental management, strategic attitude, and transfer, various activities and activity expressions were emphasized to have a risk to overshadow the findings of supporting the culture of thinking.

Aim. This study was carried out to evaluate polymorbidity taking into account geriatric syndromes and their relationship with the course of chronic heart failure (CHF) in outpatients aged 60 years and older. Methods. We conducted an open, prospective, non-randomized study. The main group included 80 patients with CHF, the comparison group – 40 patients without CHF. Conducted clinical examination, ECG, echocardiography, two-photon X-ray absorptiometry. The scale of assessment of clinical status in CHF,Charlson comorbidity index were used. The criteria for frailty were the presence of at least 3 signs due FRAIL scale. Mean follow-up was 24.1±13.0 months. Results. All patients with CHF (100%) and 92.5% of the comparison group had a concomitant pathology. A combination of 3 or more of any diseases was more common in CHF compared to control group (p=0.008), CKD (66%) and obesity (35%) were the most common pathology. Combinations of osteoporosis and CKD (28%), obesity and CKD (23%) were the most frequent in the CHF patients, a combination of obesity and CKD (28%), obesity and diabetes (18%) – without CHF patients. The same incidence of osteoporosis (p=0.768), falls (p=0.980), fractures (p=0.549) and frailty (p=0.828) was observed in CHF patients and different EFLV, but prevalence of frailty was observed at the age of 75 years and older. During the observation period, 24% CHF patients and 5% patients without CHF (p=0.022) died. The worst survival of patients with ischemic genesis of CHF and osteoporosis was noted. The factors associated with an increased risk of death in CHF patients were the ischemic etiology of CHF (OR 8.33; 95% CI 1.11–62.4; p=0.039), male gender (OR 7.91; 95% CI 2.3–27.2; p=0.001), LV EF <45% (OR 2.52; 95% CI 1.01–6,27; p=0.047), low bone mineral density in femoral neck region (р=0.016, ОR 4.3, 95% CI 1.3–17.2), comorbidity score (OR 1.19; 95% CI 1.04–1.37; p=0.012), a total score on the scale of assessment of clinical status in CHF (OR 1.13; 95% CI 1.03–1.24; p=0.008). Conclusion. All СHF patients had concomitant diseases, CKD and obesity were the most common pathologies. The ischemic etiology of CHF, along with the male gender, LV EF less than 45%, severe clinical statusand high score on the Charlson comorbidity index turned out to be risk factors for death in outpatients aged 60 years and older with CHF.

Background: Cervical cancer is still one of the most common cancers affecting females in India, leading to a lot of mortality and morbidity. The objective of this study was to assess the awareness of the human papillomavirus (HPV) infections and vaccination among the medical students of a tertiary care teaching hospital.Methods: A total 300 final year I and II medical students were requested to complete a questionnaire regarding cervical cancer, primary and secondary preventive measures and attitude of students towards HPV vaccination and the answers were then analysed.Results: Among 300 medical students, 46.6% were males and 53.4% were females. Most of them were aware of the common risk factors like early marriage (92.7%), multiple partners (99%), multiparity (83.3%) and HPV exposure (85.7%). Most were aware of the cervical cancer symptoms like offensive vaginal discharge (70%), irregular vaginal bleeding (92.7%) and postcoital bleeding (80.3%). 90% were aware that cervical cancer is preventable and 74% were aware that vaccine is available in India. 70% were aware about the best age to vaccinate is 9-13 years. About 10% were already vaccinated and all were females. Out of 270 students who have not administered HPV vaccine, 53.4% didn’t take the vaccine because of lack of awareness. High cost (18.8%), fear of side effects (13.8%) and doubt on efficacy (14%) were the other reasons reported for non-administration of vaccines.Conclusions: The study showed that there were gaps in knowledge regarding HPV infection and vaccination existed amongst the medical students. So, awareness among the students should be created and a more integrated teaching regarding various aspects of HPV infection, cervical cancers and its prevention needs to be introduced in the medical education system.
