Authors: Chong Maureen Siew Fang , Shahrill Masitah , Li Hui-Chuan 
Published: June 2019

A mathematics framework was developed to integrate problem-solving that incorporated simulation of real-life problems in the classrooms. The framework coined as the RECCE-MODEL emphasised understanding and thinking with a view on mathematics embedded in real-life. The RECCE which stands for Realistic, Educational, Contextual, Cognitive, and Evaluation encompass the underlying principles of teaching problem solving and guide teachers in planning, designing, developing, and facilitating real-life activity tasks in developing students’ problem-solving competencies in mathematics lessons. It also explores students’ cognitive competency in their application of abstract mathematical knowledge into real-life problems based on students’ developmental status of their thinking and reasoning skills correlating to Meanings, Organise, Develop, Execute and Link (MODEL). This study investigated the affective development of the students through activity tasks developed by the sampled teachers using the principles within the framework. In total, 94 students from two high schools in Brunei Darussalam responded to a students’ questionnaire constructed to address the MODEL aspect of the framework. In particular, the analyses involved the students’ affective competencies that corresponded to a 19-item instrument within the questionnaire. The findings showed that Brunei high school students have stimulated beliefs and positive attitudes towards non-routine problem-solving in the learning of mathematics. Meanwhile, meaningful activities developed by the teachers encouraged the development of cognitive-metacognitive and affective competencies of the students. The RECCE-MODEL framework paved the way towards understanding the relationships between effective pedagogical approaches and students’ learning, and between attitudes and cognitive abilities, and also for teachers to make better-informed decisions in the delivery of the curriculum.

Published: June 2019

El estrés laboral docente, y su impacto en la efectividad escolar es un tema relevante y de importancia, tanto científico como social. Estudiar el estrés laboral del magisterio es una necesidad en el contexto educativo pues permite trazar medidas preventivas y de afrontamiento. El contexto de la posmodernidad y de un mundo tecno-globalizado, repercute en este nivel educativo tanto en su misión como en su función social, los trabajadores de educación básica no solo tienen por encargo la formación del niño o adolescente, sino también cubrir los espacios de aprendizaje que la familia no puede suplir unido a las demandas de eficacia y a la influencia de las condiciones de trabajo en la cultura organizacional escolar.
El propósito del presente estudio fue determinar un modelo explicativo que corrobore el efecto moderador del liderazgo transformacional sobre el efecto negativo del estrés laboral sobre la efectividad escolar en los docentes de escuelas de educación básica de Ciudad Guzmán, Jalisco. Se asumió un diseño de investigación de tipo no experimental transversal y con alcance explicativo. Se declara de esta forma, pues se observa el estilo de liderazgo, el estrés laboral y la efectividad escolar, tal como se presentan en el contexto de la educación básica por lo que no se construye ninguna situación, sino que se observan situaciones ya existentes. La metodología es cuantitativa, se utiliza un modelo de moderación a través de la interface process en el programa SPSS.25.
Se evidencia en el presente estudio, que existe, relación –negativa- entre el estilo de liderazgo transformacional y el estrés laboral docente percibido. En el mismo tenor, se muestra como hallazgo la relación negativa entre el estrés laboral y la efectividad escolar percibida. Se demuestra que, a mayor estrés, menor será la percepción de efectividad escolar, por tanto, el resultado avala la necesidad de intervención para reducir el estrés laboral y potenciar la efectividad de las escuelas estudiadas. El liderazgo transformacional constituye un modulador del estrés laboral y la eficacia escolar por lo que se demuestra que directores capaces de influir como modelos en sus trabajadores, con adecuado uso del carisma y tolerancia psicológica, así como con una actitud personalizada y más humana hacia sus trabajadores garantizarán escuelas que resulten menos afectadas por estrés laboral, más efectivas en su misión social, organizacional y, por tanto, más saludables.

Published: June 2019

Abstract

Aim: To study the differences in cardiovascular risk between type 2 diabetic and non-diabetic patients with asymptomatic hyperuricemia and gout using the Framingham Risk Score (FRS) and complex multimodal ultrasonography.

Patients and methods: A total of 201 patients participated, divided into two groups: 1/ patients with asymptomatic hyperuricemia (n = 52), and 2/ patients with gout (n = 149). FRS was determined as well as ultrasound parameters, independent predictors of cardiovascular risk: left atrial size (LA), intima-media thickness (IMT) and common carotid artery resistive index (CCARI).

Results: The patients in the two groups were age-matched and conventional cardiovascular risk factors were equally distributed. In the asymptomatic hyperuricemia group, 12 patients (23.1%) had diabetes. In this group, there was no difference in FRS between diabetic and non-diabetic individuals. However, diabetic patients had larger LA, thicker intima-media and higher CCARI. In the gout group 18 subjects (12%) had diabetes, but the FRS, LA, IMT and CCARI values were similar among diabetic and non-diabetic patients. Furthermore, when gout subjects were subdivided according to the presence of tophi, we found that the subgroup having gouty tophi and diabetes had larger LA (p = 0.014) compared to those with gouty tophi without diabetes.

Conclusion: In diabetic patients with asymptomatic hyperuricemia and gouty tophi, a more complex approach for estimation of cardiovascular risk is needed. Our work suggests that diabetes and tophi might potentiate their action on the cardiovascular system.
The Influence of Gait Pattern with Aids on the Patient’s Recovery in an Early Period of Total Knee Replacement
Authors: Vassileva D. , Nedelcheva I. , Mindova S. , Karaganova I. 
Published: June 2019

Abstract

Introduction: The total knee replacement is the definitive treatment for knee osteoarthritis (OA). It is an effective intervention to correct OA-related functional limitation. In such patients postoperatively are observed significant differences in the biomechanics of the two knee joints. While bearing the body weight the unoperated knee joint becomes very painful, stiff and incapable of neutral positioning. These factors significantly hamper the initial training in gait with aids in the standard locomotive stereotype immediately after surgery for knee joint replacement, where walking plays an essential role in daily activities and has varied health benefits.

Aim: The aim of the study was to check whether different types of gait with aids in the early postoperative period after total knee replacement have a different influence on the recovery process.

Material and methods: This study was conducted between January 2017 and July 2018 in the Department of Orthopedics and Traumatology of the University Hospital “Kanev” – Rousse. It included 56 patients with unilateral total knee replacement after gonarthrosis, divided into a control and experimental group, each of 28 patients. All patients in both groups had knee extension deficit of the untreated knee joint. The patients in both groups followed the same physiotherapy programs, performed from about the 2nd postoperative day to the 21st day when they were discharged from the department. The difference between the patients in both subgroups was their gait pattern with two axillary crutches.

Results and Discussion: There were statistically significant differences between both groups. One of the most significant differences was in ROM. In the experimental group patients, flexion was improved with an average of 20° more than in the control group patients. Also, in the operated joint, the patients in the experimental group had no contracture, whereas those in the control group showed 15° at the end of the follow-up period.

Conclusion: The results of the study show that the choice of gait training in the following order “crutches, operated leg, crutches, untreated leg” in patients with extensor deficiency and contracture in the untreated knee is more appropriate than the standard type of training in walking with aids.

Published: June 2019

Abstract
Cocaine is a natural alkaloid extracted from the leaves of the South American plant Erythroxylum coca or synthesized chemically. After cannabis, it is the second most frequently abused recreational substance worldwide. Cocaine can affect every tissue and organ within the human body, including the kidneys, causing tissue ischemia due to vasoconstriction, endothelial dysfunction and damage, procoagulant activity and oxidative stress with subsequent ischemic infarctions and fibrosis. The renal changes in cocaine abuse and addiction are due to rhabdomyolysis, ischemic, hypertensive, and inflammatory changes with the development of cell proliferation and fibrosis. The authors present three patients with cocaine-associated renal damage and discuss the underlying mechanisms of cocaine-induces tissue changes.

Authors: Al-Obaidi F. , Al-Kinani T. , Al-Ali M. H. , Al-Myahi M. H. 
Published: June 2019

Abstract

Background: Atrial fibrillation is a relatively common complication of acute myocardial infarction with significant impact on the short and long-term prognosis.

Methods: A systematic literature review was done through Pubmed and CENTRAL to extract data related to new-onset atrial fibrillation following primary PCI.

Results: Searching resulted in twenty-one matched studies. Extraction of data showed an incidence rate of new-onset atrial fibrillation (2.8%-58%). A negative impact was found on the outcomes of patients treated with primary PCI with increased short and long-term mortality and morbidity.

Conclusion: New-onset atrial fibrillation is an adverse prognostic marker in patients with acute myocardial infarction treated invasively. Preventive measures and anticoagulant therapy should be considered more intensively in this subset of patients.

Published: June 2019

Abstract
Every year, many people in the world lose their homes due to natural disasters such as earthquakes, floods and so on. In critical situations, the use of prefabricated parts in the buildings has many technical and economic advantages. Hence, today, this technology is widely used in the industrialized societies. The purpose of this research is to provide an appropriate model for speeding up the process of constructing buildings using prefabricated parts in critical conditions. To do this, Analytic Network Process (ANP) approach has been used to select the best option for speeding up construction projects using prefabricated parts and in critical situations. In this study, the intended criteria are quality, time, cost, and strength. The options that we should compare and the best option among them, according to the criteria mentioned, are Lightweight Steel Frame (LSF) parts, steel parts and concrete parts. In order to find this prioritization, the viewpoints of civil engineers and construction experts have been used. It should also be noted that for the ANP method, the Super Decisions software has been used.
Propagation of Surface Waves in Asphalt Pavements Generated by Different Load Impulse of Falling Weight Deflectometer
Authors: Komačka Jozef , Březina IIja 
Published: June 2019

Abstract
The propagation of waves generated by load impulse of two FWD types was assessed using test outputs in the form of time history data. The calculated travel time of wave between the receiver in the centre of load and others receivers showed the contradiction with the theory as for the receivers up to 600 (900) mm from the centre of load. Therefore, data collected by the sensors positioned at the distance of 1200 and 1500 mm were used.
The influence of load magnitude on the waves propagation was investigated via the different load force with approximately the same load time and vice versa. Expectations relating to the travel time of waves, depending on the differences of load impulse, were not met. The shorter travel time of waves was detected in the case of the lower frequencies. The use of load impulse magnitude as a possible explanation was not successful because opposite tendencies in travel time were noticed.

Published: June 2019

Abstract
The influence of types and parameters of hollow microspheres in the composition of syntactic foams on their structure and coefficient of thermal conductivity has been studied. By using structural and thermal analysis it has been found that the volume concentration and the size of the ceramic and glass hollow microspheres have a strong impact on the density and thermophysical properties of the thin syntactic foams coatings. It has been shown that the best heat insulating properties belong to syntactic foam with composition of 60 vol. % ceramic microspheres with particle size of 1 - 40 μm (k = 0.029 W/m·K, R = 0.008 (m2·K)/W) and with composition of 80 vol. % glass hollow microspheres with particle size of 9 - 25 μm (k = 0.087 W/m·K, R = 0.008 (m2·K)/W). The results demonstrate that application of syntactic foams as thin insulating coatings is appropriate and they are an energy efficient material with number of benefits compare with the common thermal insulators.

Published: June 2019

Abstract
Due to the fact that dams are considered one of the strategic infrastructures of a country, it is very important to protect it against destructive acts. Accordingly, sensors were used at various points to record structural responses to the dam. Based on the questionnaires completed by experts, accuracy had the score of 3.8 so it was considered as the most important feature of the sensors and the optical fiber sensor with a mean score of 3.93 was selected as the best sensor type among the available ones. For this project, a questionnaire was prepared based on Likert scale and SPSS method was used in TOPSIS software. Then, Seimare concrete double curvature arch dam was simulated in ABAQUS 2017 software and the proper positioning of the sensors for optimum performance was determined based on Finite Element Method analysis and according to structural control criteria such as tension, displacement, strain, velocity and so one.

Published: June 2019

Abstract
In this work considerations concerning eccentrically loaded socket footing with cut-off pyramid shaped socket were presented. As an object of study sloped footing with 1.40 m height, corresponding to the maximum frost depth has been adopted. Knowing that in practice there are no perfect pure axial loads, load applied on the eccentricity has been taken into considerations. Eccentric loads result in footing rotation in the direction of eccentricity and acting load, hence one footing end is imbedding into the ground, whereas second end tries to rise up. To observe that phenomenon, elastic type of support under the foundation was introduced corresponding to the naturally humid sand with medium compaction. Presented in this paper considerations of innovative connection technology between footing and column were based on performed numerical studies. Advantages and disadvantages of presented footing in comparison to normal socket footings solutions were widely discussed. Numerical analyses were performed with the utilization Finite Element Method based SolidWorks software.
The Meshfree Localized Petrov-Galerkin Approach in Slope Stability Analysis
Authors: Niemiec Dominik , Bulko Roman , Mužík Juraj 
Published: June 2019

Abstract
The article focuses on the use of the meshfree numerical method in the field of slope stability computations. There are many meshfree implementations of numerical methods. The article shows the results obtained using the meshfree localized Petrov-Galerkin method (MLPG) – localized weak-form of the equilibrium equations with an often used elastoplastic material model based on Mohr-Coulomb (MC) yield criterion. The most important aspect of MLPG is that the discretization process uses a set of nodes instead of elements. Node position within the computational domain is not restricted by any prescribed relationship. The shape functions are constructed using just the set of nodes present in the simple shaped domain of influence. The benchmark slope stability numerical model was performed using the developed meshfree computer code and compared with conventional finite element (FEM) and limit equilibrium (LEM) codes. The results showed the ability of the implemented theoretical preliminaries to solve the geotechnical stability problems.
Network Effects on Rhythms of Scientific Publications
Authors: Oană Iulian 
Published: June 2019

Abstract
Studies based on bibliometric records have introduced the idea of ‘rhythmicity’ when it comes to the publication of research articles. However, the main approach of this particular topic was to analyze journal specific data on rates of manuscript and review submissions. This study takes another path, by analyzing aspects of publication rhythmicity based not on individual, attribute data, but taking into account the fact that publication of research results and the efforts leading to a certain manuscript are often collective endeavors. Thus, co-authorship ego networks are interpreted through the theoretical lenses of ‘social time’ (for temporality), and ‘homophily’ and ‘preferential attachment’ (for network characteristics). For this article, the same data analyzed by M.-G. Hâncean and M. Perc in their 2016 article, Homophily in coauthorship networks of East European sociologists, were used. The data was based on Web of Science bibliometric records for three populations of academic sociologists, from Poland, Romania and Slovenia, and their co-authors. The purpose was to see if the publishing rhythm of an author (i.e., ego) is influenced by the publishing rhythm of her co-authors (i.e., alters) and by the structural characteristics of her ego-network. Rhythmicity was measured as the sum of standard deviations from the mean for the number of articles published between 2006 and 2016, resulting in a score which characterizes egos and alters as constant or irregular in their publishing activity. Results suggest that the structural features of the co-authorship networks can give us certain insights for the rhythmicity of publications. Mainly, structural features of network size, density and node betweenness explain more the variation of egos’ constancy or irregularity in (non)publication than the rhythmicity of their co-authors.

Published: June 2019

Abstract
The purpose of this article is to identify, organize and analyze the international scientific production on social enterprises (SE). It presents the results of a bibliometric study combined with a systematic literature analysis. We analyzed 204 academic articles on the subject, from four different sources: (i) articles published in journals with high impact factors; (ii) most cited articles as per Google Scholar; (iii) articles addressing topics related to SE; and (iv) articles from the Social Enterprise Journal, specialized in the subject. Results point to remarkable recent growth in the field of SE, both theoretically and empirically. In addition, this study presents the main pieces of work, countries, institutions, research questions, methodology and results found in the SE literature. Studies have concentrated around six main categories: (1) understanding SE, through different approaches, concepts and models; (2) governance and relationships with stakeholders; (3) attempts to increase practical references and samples within the field; (4) organizational learning, structure and critical factors for success and failure of SE; (5) metrics, indicators and social impact generated by SE; and (6) legislation of different countries and how it relates to SE.
The Always Embedded State: Six Types of State-Society Interaction
Authors: Negoita Marian 
Published: June 2019

Abstract
This paper offers a critical analysis of the concept of embeddedness as currently used in political sociology and state theory. It argues that the concept of embeddedness can be successfully used to solve a current theoretical impasse – namely, how to conceptualize statesociety relations. The paper creates a conceptual space at the intersection of two axes of variation: the pattern of embeddedness (mono-versus multi-embeddedness) and the degree of state autonomy (captive versus autonomous). A central finding of this paper is that at least six types of embeddedness can be shown to exist in this conceptual space. In the remainder of the paper, the six types are described using a range of evidence extracted from the literature. One major advantage of the proposed typology is that it is able to incorporate, under the same umbrella, a variety of preexisting approaches of state-society interactions.
