O lugar dos objetos de ensino nos livros didáticos de Português do Ensino Fundamental II: alterações, deslocamentos e permanências ao longo dos tempos
Authors: Cargnelutti Joceli 
Published: December 2019

As pesquisas envolvendo livros didáticos procuram lançar sobre esse objeto diferentes olhares: alguns com tons prescritivos, críticos ou de denúncia; outros mais investigativos. No entanto, o importante é lançar um olhar diferente, que o investigue, descreva, compreenda, que se lance do lugar de uma história e de uma sociologia do ensino. É necessário que se busque uma perspectiva sócio-histórica do livro didático (Soares, 1996). Na tentativa de melhor conhecer a constituição do ensino de língua portuguesa, via livro didático, busco, neste artigo, investigar os objetos de ensino selecionados nas unidades didáticas de coleções de livros didáticos do Ensino Fundamental II, publicados antes e na vigência do Programa Nacional do Livro Didático (PNLD; verificar a ênfase dada a cada objeto de ensino, nas diferentes coleções, bem como pontuar as permanências, as alterações e os deslocamentos ocorridos, nas unidades didáticas, a partir da seleção dos objetos de ensino. Para tanto, a pesquisa se sustenta na perspectiva teórica sócio-histórica, a qual permite compreender a unidade didática a partir de um processo histórico, e o livro didático enquanto um dos instrumentos responsáveis por assegurar a aquisição dos saberes e das competências julgados indispensáveis à inserção das novas gerações na sociedade (Soares 1996). O corpus da pesquisa é constituído por obras didáticas publicadas antes da vigência do PNLD (período das décadas de 1960, 1970 e 1980) e na vigência do Programa (coleções de 1999, 2002, 2005, 2008 e 2011). O que foi possível depreender, a partir dos elementos, é que os livros didáticos são um sinalizador dos processos de permanência, de alteração e de deslocamentos no ensino de língua de Língua Portuguesa.

Published: December 2019

Background: Diabetes Mellitus (DM) is a chronic and non-communicable disease that has serious impacts. Previous studies have focused on a single intervention in the management of DM. Therefore, EMAS (education, nutrition management, physical activities, and stress management) interventions are proposed to convey the pillars of diabetes mellitus as endorsed by the Indonesian Ministry of Health.Purpose: This study aimed to analyze the effects of EMAS interventions on the knowledge, attitudes, skills, and glucose control in patients with type-2 DM.Methods: This study used a pretest-posttest quasi-experimental design without control groups. The samples were 86 diabetic patients recruited using a purposive sampling technique. The EMAS interventions were conducted for six months and eight sessions (October 2018 to March 2019). The EuroQoLfive-dimensional (EQ-5D) questionnaire was used to collect the data, and the paired t-test was used for data analysis. Results: The results showed that there were significant differences in the knowledge, attitudes, skills (p=0.001), and glucose control (p=0.04) of type 2 diabetes mellitus after the implementation of EMAS interventions. Conclusion: EMAS interventions significantly increased the knowledge, attitudes, and skills in patients with type 2 diabetes to behave healthier to control their blood sugar. Community nurses can use EMAS intervention for the management of DM among diabetic patients.
Electrodynamics in Euclidean Space Time Geometries
Authors: Schliewe Jörn 
Published: December 2019

AbstractIn this article it is proven that Maxwell’s field equations are invariant for a real orthogonal Cartesian space time coordinate transformation if polarization and magnetization are assumed to be possible in empty space. Furthermore, it is shown that this approach allows wave propagation with finite field energy transport. To consider the presence of polarization and magnetization an alternative Poynting vector has been defined for which the divergence gives the correct change in field energy density.
Idling Performance under Valve Deactivation Strategy in Port Fuel Injection Engine
Authors: Paimon A. S. , Rajoo S. , Jazair W. , Abas M. A. , Che Daud Z. H. 
Published: December 2019

This paper investigates the effect of valve deactivation (VDA) on idling performance in port fuel injection (PFI) engine. The test was conducted on 1.6L, 4-cylinder engine with PFI configuration. One of the two intake valves in each cylinder was deactivated (zero lift on deactivated port) and fuel injector was modified to only provide fuel spray on the active intake port. In-cylinder pressure was recorded by the combustion analyzer in order to measure and analyze the combustion characteristics. From the test, there are up to 6% of fuel consumption improvements across all the test conditions. Better combustion stability is achieved at very low idling speed (throttle position, TP = 2%) as a lower coefficient of variation of engine speed (COVrpm) and coefficient of variation indicated mean effective pressure (COVimep) were recorded. Increased intake velocity and swirl flow in the VDA strategy creates more turbulence intensity causing higher heat release rate and faster combustion. However, there is no significant difference in the pumping work during the intake cycle but there is extra pumping work recorded towards the end of expansion stroke due to the very early end of combustion. Therefore, valve deactivation strategy provides limited positive improvement to the idling performance in PFI engine.

Published: December 2019

The present research is performed while turning of JIS S45C hardened structural steel with the multilayered (TiN-TiCN-Al2O3-TiN) CVD coated carbide insert by experimental, modelling and optimisation approach. Herein, cutting speed, feed rate, and depth of cut are regarded as input process factors whereas flank wear, surface roughness, chip morphology are considered to be measured responses. Abrasion and built up-edge are the more dominant mode of tool-wear at low and moderate cutting speed while the catastrophic failure of tool-tip is identified at higher cutting speed condition. Moreover, three different Modelling approaches namely regression, BNN, and RNN are implemented to predict the response variables. A Back-propagation neural network with a 3-8-1 network architecture model is more appropriate to predict the measured output responses compared to Elman recurrent neural network and regression model. The minimum mean absolute error for VBc, Ra and CRC is observed to be as 1.36% (BNN with 3- 8-1 structure), 1.11% (BNN with 3-8-1 structure) and 0.251 % (RNN with 3-8-1 structure). A multi-performance Optimisation approach is performed by employing the weighted principal component analysis. The optimal parametric combination is found as the depth of cut at level 2 (0.3 mm)-feed at level 1 (0.05 mm/rev) – cutting speed at level 2 (120 m/min) considered as favourable outcomes. The predicted results were validated through a confirmatory trial providing the process efficiency. The significant improvement for S/N ratio of CQL is observed to be 9.3586 indicating that the process is well suited to predict the machining performances. In conclusion, this analysis opens an avenue in the machining of medium carbon low alloy steel to enhance the machining performance of multi-layered coated carbide tool more effectively and efficiently.
New Methodology for Inertial Identification of Low Mobility Mechanisms Considering Dynamic Contribution
Authors: Calderón L. A. M. , Piedrahita C. A. R. 
Published: December 2019

Knowledge of dynamic parameters of mechanical systems is required in different applications, particularly in the simulation and control problems. In this paper, the standard identification methods are discussed and a new methodology for identification of inertial parameters is raised when the closed chain has low mobility. The methodology includes formulating a symbolic model based on the transfer of inertial properties and a reduction using dynamic contribution indices based on CAD approximations. The new method is applied to the front suspension of an electrical vehicle. After applying the procedure, a model with few parameters that allows accurately reproducing the dynamic behaviour of the system is obtained. A novel methodology has been developed that allows the identification of dynamic parameters in low mobility mechanical systems.

Published: December 2019

Millions in the world suffering diabetes mellitus depends on insulin therapy to control their blood glucose level daily. However, the painful daily injections they need to take could lead to other complications if it is not done correctly. To date, it is suggested by many researchers and medical doctors that the needles should be inserted at any angles of 90º or 45º. Nevertheless, this recommendation has not been supported by clinical or biomechanical evaluation. Hence, this study evaluates the needle insertion for insulin therapy to find the favourable angles in order to reduce injury and pain onto the skin. Finite element analysis was done by simulating the injection of three-dimensional (3D) needle model into a 3D skin model. The insertions were simulated at two different angles, which are 45ºand 90º with two different lengths of needles; 4 mm and 6 mm. This study concluded the favourable angle for 4 mm needle to be 90º while 6 mm needle was best to be inserted at 45º as these angles exerted the least maximum stress and strain onto the skin.

Objectives
Previous studies have reported an association between Internet gaming disorder (IGD) and depression, but the directionality of the relationship remains unclear. Therefore, we examined the reciprocal relationship between level of depressive symptoms and IGD among children in a longitudinal study.

Methods
Research panels for this study consisted of 366 elementary-school students in the iCURE study. All participants were current Internet users, so they could be considered an at-risk population for IGD. Self-reported severity of IGD features and level of depression were assessed by the Internet Game Use-Elicited Symptom Screen and Children’s Depression Inventory, respectively. Follow-up assessment was completed after 12 months. We fitted cross-lagged structural equation models to investigate the association between the two variables at two time points contemporaneously.

Results
The cross-lagged analysis revealed that level of depression at baseline significantly predicted severity of IGD features at the 12-month follow-up (β = 0.15, p = .003). Severity of IGD features at baseline also significantly predicted level of depression at the 12-month follow-up (β = 0.11, p = .018), controlling for possible confounding factors.

Conclusions
The cross-lagged path analysis indicates a reciprocal relationship between severity of IGD features and level of depressive symptoms. Understanding the reciprocal relationship between depressive symptoms and severity of IGD features can assist in interventions to prevent both conditions. These findings provide theoretical support for prevention and remediation plans for IGD and depressive symptoms among children.

Türkiye-Mısır ilişkilerinde ekonomik dinamiklerin etkisi
Authors: SARIASLAN Fatma 
Published: December 2019

Ortak tarihsel ve kültürel
hafızaya sahip olan Türkiye ve Mısır arasındaki diplomatik ilişkiler 1925
yılında başlamakla birlikte, iki ülke arasındaki ekonomik ilişkilerin
1950’lerin ikinci yarısında kurulduğu göz önüne alındığında ekonomik
ilişkilerin iki taraf için de uzun yıllar belirleyici bir unsur olarak
görülmediği anlaşılır. 1970’lerde gerek Soğuk Savaş’ın yumuşama evresine
girmesi gerekse Enver Sedat yönetimindeki Mısır’da liberal politikalar
izlenmeye başlamasıyla siyasi ilişkilere paralel olarak ekonomik ilişkilerde de
yakınlaşma yaşanmış, ancak özellikle ikili ticari ilişkilerde ivme ancak
Türkiye’deki dışa açılma süreciyle 1980’lerde yakalanabilmiştir. Soğuk Savaş’ın
sona ermesiyle dış politika söylemlerindeki örtüşme ekonomik ilişkilerde yansımasını
bulmuş olmakla birlikte, asıl sıçrama 2005’te imzalanan Serbest Ticaret
Anlaşması ile ve özellikle Türkiye’nin Mısır’da yapmış olduğu yatırımlarla
mümkün olabilmiştir. İki ülke arasında tesis edilmiş olan ekonomik ilişkilerin,
Mısır’da yaşanan devrim ve ardından yapılan askeri darbeden kaynaklanan siyasi
iniş çıkışlardan etkilenmekle birlikte, 2005 sonrasında yakalanan seviyenin
altına düşmediği gözlemlenmektedir. Bu
bağlamda çalışmada, Türkiye ve Mısır arasındaki ilişkilerin ekonomi ve siyasi
alanların karşılıklı etkileşimlerinden ne ölçüde ve ne yönde etkilendiği
hususuna cevap aranmaktadır. Bu çerçevede karşılıklı ticaret verilerine ve
doğrudan yatırım ilişkilerine yer verilen çalışmada, Ankara-Kahire
ilişkilerinde ekonomik rasyonalitenin belirleyici etkisine vurgu yapılmaktadır.
