This research aims to describe the application of curriculum k13, especially scientific steps on the PAI (Islamic Education) subject in Islamic Elementary School Bina Insani Muslim Jatimulya in South Tambun subdisstrict, Bekasi Regency. The research instruments consist of observation, interview and documentation. The data of the research are analyzed employing a qualitative descriptive technique. The result of the one-month research shows that the scientific steps have been implemented as a whole. However, its implementation is not in accordance with the regulations of Minister of Education and Culture of Republic of Indonesia, consisting of 5 steps: observing, asking, trying, reasoning or associating and communicating. The inadequacy of the scientific steps in PAI learning can be seen in its non-sequential implementation. In the observing step, the aspect of aqidah (faith) is a dominant obstacle because it contains the concept of knowledge that is related to a belief and its abstract character. The discussions in this step tend to be rowdy and not focused. Besides, the imitating activity is only applied to aspects of fiqih (jurisprudence), such as the material of cleaning procedure. In the associating step, especially on the aspects of Al-Qur'an and hadith, students find it difficult to associate the contents of Al-Qur'an with the phenomena in their daily life, especially for students who have just learned to read Al-Qur'an. The last one is communicating ideas has not organized yet and tends to be quiet.

Testing potential psychological predictors of attitudes towards cultured meat
Authors: Wilks Matti , Phillips Clive J C , Fielding Kelly , Hornsey Matthew
Published: February 2019

Cultured meat is an emerging food technology that has the potential to resolve many of the social, environmental and ethical issues surrounding traditional factory farming practices. Recently, research has begun to explore consumer attitudes to the product, revealing a number of barriers and demographic predictors. However, our understanding of the psychological mechanisms that underpin attitudes to cultured meat remains limited. In the current study, we draw on an attitude roots model (Hornsey & Fielding, 2017) to explore a range of psychological mechanisms that may underpin attitudes to cultured meat. In terms of negative attitudes and intentions toward cultured meat, the most powerful predictors were food neophobia, political conservatism, and distrust of food scientists. When it comes to absolute opposition to cultured meat - defined by the unconditional belief that it should never be allowed under any circumstances - the strongest predictors were food and hygiene disgust sensitivity subscales, food neophobia, and conspiratorial ideation. A number of presumed mechanisms held no relationships to cultured meat attitudes, including social dominance orientation, speciesism, and naturalness bias. The null results on naturalness bias are of particular interest given recent research identifying concerns about naturalness as a key barrier to consumer acceptance. These results demonstrate the need for a more nuanced understanding of the psychological mechanisms that contribute to cultured meat attitudes and engagement.

In regard to Islam, Indonesia as the largest Muslim democracy in the world, the location and power of youth present a unique experience to form professional relationships, develop projects and advance policies that are vital for national security and human well being in term of environmental development. This paper addresses some of practices of Islamic students which a part of environmental improvement and partnertship mainly derived from their youth spirit. In addition, it also aims to explore actual experience with regards to contribution within the organizational context. The study performed in Himpunan Mahasiswa Islam (HMI, The Association of Islamic University Students) in Indonesia. They live out on experiential learning approach to explore opportunity to participate on sustainable city growth. Data was collected through interviews with 25 number of informants and documents on many activities and series of environment agenda. They are part of Pengurus Besar (national board) in Jakarta. The respondents were asked to define their organizational policy on environment and natural resources. At the same time, they were also asked to describe their experience in their projects. Respondents’ descriptions of their experiences on the project work were compared to one another, even though they are engaged to the same type of projects. Students’ experience of program on environment is undeniably important in enhancing a better performance on national progress. With such experience in hand, they will contribute towards a better atmosphere. The programs enable students to present their spirit and power in building better environment. Additionally, programs provide a platform for dialogue and the exchange of ideas. They bring forward voices from cultures and situations that are typically not included in environment discourses, to empower local communities and to build a national community that promotes environment policy and action. The paper concludes with a number of implications and research direction to enrich the knowledge of student participation in the development sustainable cities. They expect to explore in a setting conducive to constructive involvement and also grapple with the challenges associated with non-violent social change.
Neuroscience of imagination and implications for human evolution
Authors: Vyshedskiy Andrey
Published: February 2019

Vivid dreaming often conjures-up imaginary novel images during the sleep. Humans can also imagine novel mental images consciously and purposefully in the process of Prefrontal Synthesis (PFS). Despite both processes commonly referred to as ‘constructive imagination,’ their mechanisms of mental image creation are very different. PFS is completely dependent on the lateral prefrontal cortex (LPFC) and patients with damage to the LPFC often lose their PFS ability. Conversely, dreaming is not controlled by the LPFC: the LPFC is inactive during the sleep and patients whose LPFC is damaged do not notice any change in their dreams. Other neurobiologically distinct components of imagination discussed in this manuscript include amodal completion, categorically-primed spontaneous imagination, integration of modifiers and mental rotation, and Prefrontal Analysis. Clearer neurobiological definitions of separate imagination mechanisms can lead to better understanding of hominin evolution and better educational strategies in children with neurodevelopmental delays.

Autistic traits in synaesthesia: atypical sensory sensitivity and enhanced perception of details
Authors: van Leeuwen Tessa Marije , van Petersen Eline , Burghoorn Floor , Dingemanse Mark , van Lier Rob
Published: February 2019

In synaesthetes specific sensory stimuli (e.g., black letters) elicit additional experiences (e.g. colour). Synaesthesia is highly prevalent among individuals with autism spectrum disorder but the mechanisms of this co-occurrence are not clear. We hypothesized autism and synaesthesia share atypical sensory sensitivity and perception. We assessed autistic traits, sensory sensitivity, and visual perception in two synaesthete populations. In Study 1, synaesthetes (N=79, of different types) scored higher than non-synaesthetes (N=76) on the Attention-to-detail and Social skills subscales of the Autism Spectrum Quotient indexing autistic traits, and on the Glasgow Sensory Questionnaire indexing sensory hypersensitivity and hyposensitivity which frequently occur in autism. Synaesthetes performed two local/global visual tasks because individuals with autism typically show a bias toward detail processing. In synaesthetes, elevated motion coherence thresholds suggested reduced global motion perception and higher accuracy on an embedded figures task suggested enhanced local perception. In Study 2 sequence-space synaesthetes (N=18) completed the same tasks. Questionnaire and embedded figures results qualitatively resembled Study 1 results but no significant group differences with non-synaesthetes (N=20) were obtained. Unexpectedly, sequence-space synaesthetes had reduced motion coherence thresholds. Altogether, our studies suggest atypical sensory sensitivity and a bias towards detail processing are shared features of synaesthesia and autism spectrum disorder.
Disentangling the facilitating and hindering effects of threat-related stimuli – A visual search study

Published: February 2019

A large body of research has demonstrated the attention-grabbing nature of threat-related stimuli. According to the results of studies using spatial cueing tasks, threat could also facilitate attentional processes. However, it was pointed out that it is not clear whether the attentional draw or the facilitated processing caused by threatening stimuli lead to a better performance compared to neutral ones. Here, we aimed to disentangle the two effects by using a visual search paradigm that allowed us to separate the emotional stimuli and the cognitive task. We manipulated stimulus onset time and threat intensity. Participants saw neutral and threatening pictures as priming stimuli, and then, they had to find numbers in ascending order in a matrix array. We measured the reaction time for finding the first number, and search time for finding all the numbers. Our results showed that when the priming stimulus is presented longer threatening pictures had an attentional-grabbing effect compared to neutral ones, which was compensated by the facilitating effect of threat. We did not find any significant effects for the shorter presentation time. Further theoretical and methodological implications are discussed.

Authors: Zeng Guang , Peng Kaiping , Hu Chuan-Peng
Published: February 2019

Background. The mental health and well-being of adolescents are becoming increasingly important globally. Understanding the relationship between different aspects of well-being is crucial for effective interventions of the well-being of adolescents. The present study aims to analyze the network structure of adolescent well-being and identify the central well-being traits. Methods. We used a network model to analyze the network structure of a psychometrically sound measurement of adolescent well-being ---- the engagement, perseverance, optimism, connectedness, and happiness (EPOCH) scale. The dataset comes from a representative sample of Chinese adolescents (17, 854 participants from rural and urban areas from Southern, Northern, and the middle part of China). Results. The twenty items of EPOCH formed a highly interconnected network. The item H4 (“I am a cheerful person.”), E2 (“I get completely absorbed in what I am doing”), and O4 (“I believe that things will work out, no matter how difficult they seem”) were the most central traits. Conclusions. Cheerfulness, engagement in current activity and optimism for the future are most central to the psychological well-being of Chinese adolescents. Future studies should further test the dynamics between these central traits and other well-being traits to find effective interventions of well-being of adolescents.
Can imagination reduce prejudice over time? A preregistered test of the imagined contact hypothesis
Authors: Schuhl Jennifer , Lambert Eric , Chatard Armand
Published: February 2019

Research on the imagined contact hypothesis suggests that simply imagining a positive interaction with an out-group member can reduce prejudice towards stigmatized social groups. To date, however, it remains unclear whether imagined contact has transient or long-lasting effects. This preregistered study (N = 153) tested the hypothesis that a single session of imagined contact is sufficient for reducing explicit and implicit prejudice towards a stigmatized social group and intergroup anxiety over several days. Highlighting the power of imagination, the results suggest that imagined contact could have long-lasting effects on explicit prejudice and intergroup anxiety.

Published: February 2019

Physical activity (PA) interventions in children and adolescents are thought to improve cardiorespiratory fitness (CRF), and possibly executive function (EF), and academic performance (AP). It is thought that the impact of PA upon CRF might be associated with improved EF and AP. However, previous meta-analyses have not examined this relationships. Thus, we conducted a systematic review and meta-regression of intervention studies that reported a pre- and a post-intervention measure of CRF and AP and/or EF and included a control group. A total of 17 studies were included. PA interventions had the following main effects: 0.24 [95% CI=0.09, 0.40] for CRF; 0.11 [95% CI=-0.16, 0.38] for AP; and 0.02 [95% CI=-0.09, 0.13] for EF after removal of influential studies. Meta-regression for CRF changes upon EF outcomes suggested a small effect ranging from negative trivial to moderate (β = 0.26 [95% CI=-0.18, 0.70]). For CRF changes upon AP outcomes the estimate was trivial with poor precision ranging negative to positive large effects (β = -0.04 [95% CI=-1.52, 1.45]). Despite small positive effects upon CRF, the effects upon EF or AP are less clear. Further, it seems unlikely improvements in CRF from PA interventions are associated with changes EF or AP.

Authors: Sigdel B , Nepali R , KC Neeraj , Dubey T , Neupane B , Sigdel D
Published: February 2019

Introduction: Epistaxis is a common otolaryngological emergency condition. It occurs due to local and systemic cause. Local cause lies within the nose bleeding either anterior or posterior. Commonest site of bleeding anterior epistaxis is kiesselbach’s plexus. In posterior epistaxis, it is difficult to locate bleeding site. Epistaxis is controlled by simply pinching of nose, decongested nasal drop and abgel packing. Some cases become more challenging required nasal packing and arterial ligation.

Objectives: To study the epidemiological pattern and management of epistaxis.

Methods: This was a retrospective study on pattern of epistaxis man­aged at Gandaki Medical College Teaching Hospital over a period from April 2015 to April 2016. Information regarding demographic profile, presentation and management of epistaxis was obtained from the Hospital records, ENT Outpatient clinic, Emergency Department, ENT ward and operation theatre.

Results: A total of 78 cases were managed during study period. There was a significant male preponderance with male to female ratio 1.78:1. Patients’ age varied from eight to 80 years with mean age 40.7 years. The peak age of incidence was 21 - 30 years group. Idiopathic nasal bleeding 27 (34.6%) was commonest followed by nasal trauma 23 (29.5%) cases and hypertension 16 (20.5%) cases. Seventeen (21.8%) cases managed in day care basis with decongested nasal drop, chemi­cal cautery and abgel packing. Remaining cases required nasal packing and bipolar cautery and other specific form of treatment. Five (6.4%) cases required sphenopalatine artery ligation with no recurrence of bleeding.

Conclusions: Epistaxis is common ENT emergency. Most common causes are idiopathic followed by nasal trauma and hypertension. Prompt management is instituted according to cases. Most of the cas­es are managed by non-surgical method.

Authors: Parajuli B , Pun G , Ranabhat S , Poudel S
Published: February 2019

Objective: To study the spectrum of histopathological diagnosis of endometrial lesions and their distribution according to age.

Methods: All the endometrium samples obtained by the procedure of dilatation and curettage and hysterectomy sent for histopathological examination at Pathology Department of Gandaki Medical College Teaching Hospital, Pokhara, Nepal. The study duration was total 12 months ranging from July 2016 to June 2017. All the endometrial samples were processed, sectioned at 4 - 6 μm and stained with routine H & E stain. Patient’s data including age, sex, procedure of the biopsy taken and histopathological diagnosis were noted. A pathologist, using Olympus microscope, reported the slides. Cases were reviewed by a second pathologist whenever necessary.

Results: A total of 128 cases were studied. The most common histopathological diagnosis was proliferative endometrium (28.9%) followed by disorder proliferative endometrium (15.65%). Most of the patients were in age group 36 - 45 years comprising 32.03%. Hydatidiform mole comprised of 7.03% and among Hydatidiform mole, partial mole was more common. Dilatation and curettage (82.8%) was the common procedure in compare to hysterectomy for the evaluation of endometrial lesions.

Conclusions: In this study, we observed a variety of endometrial lesions. Most of them are benign; among benign, proliferative endometrium was the common histopathological diagnosis followed by disorder proliferative endometrium. Most common presenting age group was found to be at 36 - 45 years. In evaluation of hydatidiform mole, partial mole was more frequent in compare to complete mole. Conventional dilatation and curettage is the preferred method in developing countries with limited resource to screen endometrial lesion and therefore biopsy should be sent for histopathological examination. Thus histopathological examination of routinely stained hematoxylin and eosin is readily available and widely accepted standard technique for evaluation of the endometrial lesions.

Light Weight Complete Denture Prosthesis - A Case Report
Authors: Khanal A , Limbu IK , Parajuli PK , Suwal P , Singh RK
Published: February 2019

Retention, stability and support are the basic principles on which the success of a complete denture relies on. Extreme resorption of the maxillary denture-bearing area leads to a narrower, constricted residual ridge with decreased supporting tissues and a larger restorative space between the maxillary and mandibular residual ridge. Rehabilitation in such cases may result in increased weight and height of the prosthesis further compromising its retention, support and stability. So, to prevent further resorption of ridges, the weight of the prosthesis needs to be reduced which can be achieved by making hollow prosthesis. This case report describes a novel technique of fabricating maxillary hollow maxillary complete denture.

A. barbadensis extracts were prepared using aqueous and organic solvents and their in vitro inhibitory action was evaluated by agar well diffusion methods.

Results: Out of total, 38 (21.1%) of the wound specimens showed the occurrence of P. aeruginosa, among which 15 (39%) isolates were multi-drug resistant. Organic extracts of various concentrations (0.2 - 0.8 v/v %) inhibited 66.7% of MDR and all non-MDR (n = 23) P. aeruginosa with zone of inhibition ranging from 9.5 ±1.0 to 21.3 ± 2.2 mm but not by aqueous extract. A positive Pearson’s correlation (r=0.983) was found between antibacterial effect and concentrations of the extracts. The antibacterial activity of organic extracts was statistically associated with antibiotic resistance profile of the organism (p<0.05).

Conclusion: Organic extracts of A. barbadensis revealed variable in vitro inhibitory action against both MDR and non-MDR P. aeruginosa isolated from wound specimens. Although further confirmation is needed, aloe gel extract may be applied as an alternate treatment option.
Virtual beams and the Klein paradox for the Klein-Gordon equation
Authors: Molgado A. , Morales O. , Vallejo J.A.
Published: February 2019

Whenever we consider any relativistic quantum wave equation we are confronted with the Klein paradox, which asserts that incident particles will suffer a surplus of reflection when dispersed by a discontinuous potential. Following recent results on the Dirac equation, we propose a solution to this paradox for the Klein-Gordon case by introducing virtual beams in a natural well-posed generalization of the method of images in the theory of partial differential equations. Thus, our solution considers a global reflection coefficient obtained from the two contributions, the reflected particles plus the incident virtual particles. Despite its simplicity, this method allows a reasonable understanding of the paradox within the context of the quantum relativistic theory of particles (according to the original setup for the Klein paradox) and without resorting to any quantum field theoretic issues.
An algebraic approach to a charged particle in a uniform magnetic field
Authors: Ojeda-Guillén D. , Salazar-Ramírez M. , Mota R.D. , Granados V.D.
Published: February 2019

We study the problem of a charged particle in a uniform magnetic field with two different gauges, known as Landau and symmetric gauges. By using a similarity transformation in terms of the displacement operator we show that, for the Landau gauge, the eigenfunctions for this problem are the harmonic oscillator number coherent states. In the symmetric gauge, we calculate the SU(1; 1) Perelomov number coherent states for this problem in cylindrical coordinates in a closed form. Finally, we show that these Perelomov number coherent states are related to the harmonic oscillator number coherent states by the contraction of the SU(1; 1) group to the Heisenberg-Weyl group.
Design and construction of an apparatus to visualize incompressible fluid flow in several regimes
Authors: Iturbide Jiménez F. , Mendoza Jasso A.J. , Antonio García A. , Santiago Alvarado A.
Published: February 2019

In this work, the design and construction of a didactic experimental equipment to visualize the fluid flow behavior in the laminar, transition and turbulent regimes is presented; as well as the ability to measure and display the respective Reynolds number (Re) of each flow; current educational equipments have limited or null capacity in this regard. The equipment was designed taking into account the basic laws of fluids such as mass, momentum and energy conservation. The analytical calculations were numerically validated using the finite element method (FEM), for which the Ansys software was used in its Ansys@ Parametric Design Language (APDL) and Workbench platforms. Solidworks tools for conceptual design and Stratasys Catalist for three dimension (3D) printing were used. Additionally, hardware was implemented for the step of measuring the flow velocity, temperature and Re calculation. The apparatus is a valuable resource in fluid flow visualization since it permits to read several fluid parameters immediately from a display.
Comparative analysis of proximity potentials to describe scattering of 13C projectile off 12C, 16O, 28Si and 208Pb nuclei
Authors: Aygun M.
Published: February 2019

In this work, we examine the elastic scattering cross sections of 13C on 12C, 16O, 28Si and 208Pb target nuclei at different incident energies. For the first time, we apply six types of proximity potentials such as Broglia andWinther 1991 (BW 91), AageWinther (AW95), Christensen and Winther 1976 (CW 76), Bass 1973 (Bass 73), Bass 1977 (Bass 77) and Bass 1980 (Bass 80) in order to obtain the real part of the optical potential. The imaginary part is taken as the Woods-Saxon potential. Theoretical results are compared with each other as well as the experimental data.
Algoritmo cuántico de Deutsch y Jozsa en GAMA
Authors: Paredes López M. , Meneses Viveros A. , Morales-Luna G.
Published: February 2019

An important feature of quantum computing is its inherent paralellism, allowing to process an exponential number of basic transforms with just a linear number of qubits. The Deutsch-Jozsa algorithm exemplifies the computational complexity reduction. This work reports the implementation and execution of the Deutsch-Josza quantum algoritm in GAMA, a programming language for quantum computing simulation developed by ourselves. Through this simulation, it is possible to explore all the components involved by tracing all the different configurations that each component may take.

Authors: Ruiz Morillas E.
Published: February 2019

In this article an analysis of original historical data is made in order to evaluate the experimental errors in Boyle’s experiment. In this evaluation, statistical regression analysis is used to estimate the constant of Boyle’s law and its uncertainty. Also is used the ideal gas law, which was established much later, as a way to evaluate this uncertainty.This article may be useful to teachers and students as an example of using historical data in physics, and how statistical analysis can be applied to obtain information from these data.
Finite difference calculation of optical properties of hydrogenic impurity in spherical quantum dot with parabolic confinement
Authors: Batra Kriti , Prasad Vinod
Published: February 2019

The optical properties of an electron with an impurity in a spherical quantum dot under parabolic confinement are studied and energies, wave functions, binding energies, radial matrix elements, polarizability, susceptibility and oscillator strength have been evaluated. The numerical method used is the finite difference method in the framework of the effective mass approximation. The variation of the energy levels and radial matrix elements have been studied as function of the radius of the GaAs sphere and also as function of the frequency of the harmonic oscillator potential or parabolic potential. In addition we have studied how polarizability, susceptibility and the oscillator strength vary as a function of dot radius and at different parabolic potential frequencies.

Teaching Tip: Virtual Oncology Clinic
Authors: Nolan Michael W. , Balogh Marton , Waltman Suzanne Shelly
Published: February 2019

Due to limitations in traditional approaches to didactic and clinical learning, professional veterinary medical students face challenges in developing skills and competencies related to clinical practice. The Veterinary Information Network’s (VIN) Virtual Clinic (VVC) aims to support learning by using gaming techniques to simulate clinical case management in a low-risk setting. The VVC lets students explore medical scenarios inside a virtual hospital. The purpose of this article is to describe the development and implementation of a learning approach that blends classroom instructor-directed learning with online simulation-based learning, using the VVC. We share challenges and successes of this approach. The case vignettes in the specific example described herein are for canine multicentric lymphoma. However, the lessons learned through the implementation of this oncology clinic module are expected to apply to a wide range of clinical disciplines.
