Published: December 2019

The purpose of this study was to identify the impact of implementing a Learning Management System (LMS) ‘TES Teach’ on students’ learning experiences in a computer-assisted language learning (CALL) course with flipped-class instruction. For the data collection procedure, an individual interview with ten undergraduate students from an Indonesian college was conducted to demonstrate the potential impacts of the LMS in students’ meaningful learning activities. The observation of students’ learning activities on the LMS was also recorded to support the interview data. The LMS was adopted to distribute and receive information, thus, the students were able to monitor learning activities, learn the contents before coming to class, evaluate learning process, and interact with others outside of class hours. The finding of this study suggests that the LMS TES Teach is recommended to be performed in teaching CALL for higher education in Indonesia. It offers students’ occasion to practice and enhances their listening, writing, reading and vocabulary skills in and out-of-class times. It also prepares students to get ready for classroom activities in term of conversations and speaking skills. The further use of the LMSs should become often-visited sites by students for learning activities and replaced other non-educational favorite websites. Finally, this study recommends that the Ministry of Research, Technology and Higher education or policymakers in Indonesia, including instructors, students, and community members, must be actively involved in developing, supporting, and maintaining a transformed learning culture, from being traditional to a technology-based learning environment.

Analisa Pengujian Repeatability Timbangan Elektronik dengan Metode Syarat Teknis Timbangan Non Otomatis dan Metode NMI Australia
Authors: Wali Ponco
Published: December 2019

Testing repeat electronic scales with non-automatic scales technical requirements so far is fairly long if not using a calculator or computer. The aim of this research is to compare the repeatability testing method of electronic scales using methods according to the technical requirements of non-automatic scales and the Australian NMI method, both of which refer to OIML R76 in determining the validity or cancellation of electronic scales repeatability testing. This research method is done through repeat testing on 3 samples of electronic scales, then on each electronic scale 2 test methods are performed. The conclusion is that the electronic scales repeatability testing uses the non-automatic scales technical requirements method and the Australian NMI method has some differences although both refer to OIML R76. These differences include several points, namely the charge used, the method of adding additions, the formula for determining electronic scales, and different test results. The Australian NMI method is deemed to make it easier and more time efficient compared to the non-automatic weighing technical requirements method.
Rationale, design, and challenges with implementing a clinical intervention to teach appropriate gestational weight gain (TAGG): Protocol of a Randomized controlled trial (Preprint)
Authors: Mackeen Awathif , Downs Danielle , Hetherington Vonda , Lutcher Shawnee , Mowery Jacob , Paglia Michael , Savage Jennifer , Bailey-Davis Lisa
Published: December 2019

BACKGROUND

Excessive gestational weight gain (GWG) has public health implications including preterm birth, preeclampsia, gestational diabetes, and cesarean delivery. In an effort to mitigate adverse consequences of excessive GWG, this study tests a health intervention that includes enhancements to improve knowledge and awareness of appropriate GWG, and patient-centered nutritional counseling to promote appropriate GWG.

OBJECTIVE

The primary objective of the study was to increase the proportion of women who are managing their GWG as recommended by the IOM.4,5

METHODS

This randomized controlled trial was conducted at Geisinger in Pennsylvania where excessive GWG is common among women with pre-conception obesity. Eligible, consenting participants with pre-pregnancy body mass index >30.0 kg/m2 were randomized (1:1) to: 1) Usual Care: usual written educational materials and counseling by an obstetric care provider or 2) Enhanced Care: Usual Care plus a) a personalized letter from a physician detailing appropriate GWG, b) exposure to individualized GWG chart in the electronic health record via the patient portal, and c) a consult with a Registered Dietitian Nutritionist and follow-up via tele-health counseling (10-20 mins/1-2 weeks) for the duration of the pregnancy.

RESULTS

The primary outcome was the proportion of women that gain less than 20 pounds over the course of the pregnancy. Secondary outcomes include knowledge, expectations, and attitude about pregnancy weight gain; increased self-efficacy for ability to eat healthy and being physically active to manage weight; and eating behavior. Potential moderators that will be explored include sleep, perceived stress, perceived involvement in care, and household food security. Data collection has been completed as of November 2019.

CONCLUSIONS

As GWG care was initiated for mothers with pre-pregnancy BMI >30 kg/m2 within the first and second trimesters, the intervention may have the additional benefit of reducing other adverse pregnancy outcomes including the incidence of gestational diabetes due to healthier rates of GWG. In addition to assessing appropriate GWG, this project will assess eating habits, physical activity, GWG attitudes, sleep quality, and psychological measures, all of which are associated with GWG. Exploratory mediators including perceived stress and food insecurity will also be evaluated.

Self-Service Blood Pressure Measurement in Outpatient Obstetrics Clinics Could Reduce the Waiting Time of Pregnant Women: Cross-sectional Survey (Preprint)
Authors: Xie Wanhua , Gao Yunhe , Tan Weichi
Published: December 2019

BACKGROUND

In the conventional method, the blood pressure values of pregnant women were measured by nurses in the obstetrics outpatient clinics, and then were entered into the computer system. The pregnant women should wait for long time to complete this process. We hypothesized that the self-service blood pressure measurement by pregnant women could be a better option rather than measuring the blood pressure by nurses.

OBJECTIVE

To investigate the influence of self-service blood pressure measurement on pregnant women in the obstetrics outpatient clinics on the waiting time, patient satisfaction, and outpatient volume by comparing with the conventional blood pressure measurement method.

METHODS

The waiting time and satisfaction degree of pregnant women, as well as the outpatient volume in the Obstetrics Outpatient Clinic were compared on the use of self-service blood pressure measurement system with the conventional method. A total of 519 pregnant women in the obstetrics outpatient clinics participated in the satisfaction survey. The sample means were compared with t-test.

RESULTS

After using the self-service blood pressure measurement system, the waiting time of pregnant women for blood pressure measurement was significantly reduced from (18.57±9.68) min to (2.39±1.96) min (P<0.001). In addition, the satisfaction degree of pregnant women was significantly increased (P<0.001), and the monthly outpatient volume was significantly increased (P=0.02,P<0.05).

CONCLUSIONS

The self-service blood pressure measurement has significantly reduced the waiting time, increased the patient satisfaction and the outpatient volume. Therefore, this method is worth to be popularized in clinical practices.

Authors: Kumngern Montree
Published: December 2019

In this paper, a current-mode quadrature oscillator using second-generation current conveyors (CCIIs) is presented. The proposed oscillator consists of two CCIIs, two grounded capacitors and two grounded resistors. The circuit is suitable for integrated circuit implementation by using grounded capacitors. In addition, a new current-controlled current-mode quadrature oscillator using two current controlled second generation current conveyors (CCCIIs) and two grounded capacitors can be obtained by replacing CCIIs and resistors series at X terminals with CCCIIs. The condition of oscillation and frequency of oscillation can be orthogonally controlled. The frequency of oscillation can be controlled by grounded resistors and external bias currents. The proposed circuits have been simulated by SPICE simulations. The simulation results are confirmed the proposed theory.

Published: December 2019

Gateway redundancy can ensure the network availability and reliability in providing a service. One way is to make a backup system on the gateway. This backup system can be applied to the router so that if a failure occurs on the master router its task and function can be transferred to the slave router. The transition process from master router to slave router is known as failover. Common Address Redundancy Protocol (CARP) is one of the redundancy gateway protocols and provides a failover mechanism on the router. Therefore, this study will analyse the CARP protocol implementation in ensuring the network services availability by measuring parameters of throughput, delay, retransmission, and downtime. The results showed that CARP implementation on the network produced the throughput, delay, and retransmission values of 61.7 Mbps, 0.14 ms, and 1.11% when without the link termination and 18 Mbps, 0.53 ms, and 1.58% when with link termination, while the downtime value is 2.91 seconds. The QoS test results show good quality based on ITU-T.

Tax Holiday as an Incentive Policy Tool
Authors: Nar Mehmet
Published: December 2019

Tax holidays can be defined as elimination or reduction of the tax for a period of time. Countries may go for tax holiday practice primarily for promoting investments or for various purposes. However, tax holidays imposed by governments have been criticized in various ways. Because in practice, there is contradiction in terms about what tax holiday is and what exemption is and what should be included as an exception. Because in practice there is a conceptual ambiguity regarding what should be considered within the scope of tax holiday, what in exemption and what in exception. Therefore, the study primarily clarifies the concept of tax holiday and then discuss as to what should be understood from the concept of tax holiday.

Computational geometry as a tool for studying root-finding methods
Authors: Petkovic Ivan , Rancic Lidija
Published: December 2019

We present an efficient method from Computational geometry, a branch of
computer science devoted to the study of algorithms, for mathematical
visualization of a third order root solver. For many decades the quality of
iterative methods for solving nonlinear equations were analyzed only by
using numerical experiments. The disadvantage of this approach is the
inconvenient fact that convergence behavior strictly depends on the choice
of initial approximations and the structure of functions whose zeros are
sought, which often makes the convergence analysis very hard and incomplete.
For this reason in this paper we apply dynamic study of iterative processes
relied on basins of attraction, a new and powerful methodology developed at
the beginning of the 21th century. This approach provides graphic
visualization of the behavior of convergent sequences and, consequently,
offers considerably better insight into the quality of applied root solvers,
especially into the domain of convergence. For demonstration, we present
dynamic study of one parameter family of Halley?s type introduced in the
first part of the paper. Characteristics of this family are discussed by
basins of attractions for various values of the involved parameter. Special
attention is devoted to clusters of polynomial roots, one of the most
difficult problems in the topic. The analysis of the methods and presentation
of basins of attractions are performed by the computer algebra system
Mathematica.
Application of the geometry of curves in Euclidean space
Authors: Trencevski Kostadin
Published: December 2019

In this article the so called induced spin velocities are studied, and it is
an improvement of the paper [13] using the geometry of curves in
3-dimensional Euclidean space. Some essential properties of them are given,
and they are rather different than the ordinary velocities. Indeed, the
induced spin velocities are non-inertial and instead of the Lorentz
transformations for them the Galilean transformations should be used. The
induced spin velocity is derived in terms of the curvature and torsion of
the trajectory. Two applications of the induced spin velocities are studied.

3d point cloud model of human bio form created by the application of geometric morphometrics and method of anatomical features: human tibia example
Authors: Vitkovic Nikola , Radovic Ljiljana , Trajanovic Miroslav , Manic Miodrag
Published: December 2019

Morphometrics refers to the quantitative analysis of a biological form and it
can be used to describe its shape. Common types of geometric morphometrics
are Landmark-based Geometric Morphometrics which describe shape by using
anatomical landmarks (e.g. points), and Outline-based geometric
morphometrics which uses envelope curves to describe shape of the biological
form (e.g. bone), and they are not absolutely exclusive. Geometric
morphometrics can be used for the creation of statistical models which
represent shape variation of specific bio form. In this paper, novel
application of geometric morphometrics for the creation of personalized
models of unique bio-forms, i.e. models which are created for the specific
patient is presented. Personalized model is defined as 3D point cloud model
of biological form (in this case human tibia). Positions of points in 3D
space are determined by using set of parametric functions defined by
applying geometrical morphometrics, morphology properties and statistical
analysis on the input set of human tibia samples. By using this technique,
anatomically correct and geometrically accurate personalized models of bio
forms can be created and used in pre, intra, and post-operative procedures
in clinical practice.
On quasi-Clifford Osserman curvature tensors
Authors: Andrejic Vladica , Lukic Katarina
Published: December 2019

We consider pseudo-Riemannian generalizations of Osserman, Clifford, and the
duality principle properties for algebraic curvature tensors and investigate
relations between them. We introduce quasi- Clifford curvature tensors using
a generalized Clifford family and show that they are Osserman. This allows us
to discover an Osserman curvature tensor that does not satisfy the duality
principle. We give some necessary and some sufficient conditions for the total
duality principle.
Electrofreezing of the phase-change material CaCl2•6H2O and its impact on supercooling and the nucleation time
Authors: Sutjahja Inge , Rahman Annisa , Putri Risky , Swandi Ahmad , Anggraini Radhiah , Wonorahardjo Surjani , Kurnia Daniel , Wonorahardjo Surjamanto
Published: December 2019

This paper reports electrofreezing experiments on the inorganic phase-change material (PCM) CaCl2?6H2O by using an insulated copper electrode that is commonly sold in the market. The effect of the applied voltage or electric field to the nucleation process is measured by the nucleation temperature, freezing temperature, supercooling degree, induction time, time for supercooling, and time for crystallisation. It is found that, compared to the zero field, the freezing temperature remains nearly constant while the nucleation temperature increases with increasing applied field, leading to a reduction in the supercooling degree. The decrease in the supercooling degree is approximately 6 K for an applied voltage of V = 5.0 kV or E = 107 V m-1. With the increase in the applied field the induction time decreased considerably along with reduction of the measured data spread as compared to the no-voltage case, while the crystallisation time for the phase transformation prolonged. The overall phenomena are analysed in terms of modification of the Gibbs free energy for crystallisation owing to the applied field, with the mechanism involving bubble generation and formation of a copper-chloride complex.

El estudio cualitativo, exploratorio y descriptivo surge de dos preguntas: ¿Qué las motiva a acosar moralmente a otra mujer? ¿El acoso de la mujer es similar al del varón? La respuesta es compleja debido a la escasez de fuentes e investigaciones centradas en la mujer acosadora moral, y a la falta de casos registrados en las instituciones educativas en donde los protocolos de denuncia están dirigidos exclusivamente al acoso sexual.

El objetivo de la investigación se centra en exponer este fenómeno que se está incrementando debido a la invisibilidad de la mujer como acosadora producto del discurso actual, en donde generalmente es víctima de la violencia; sin embargo, cuando ejerce el rol contrario es aún más efectiva en paralizar y destruir de una forma sutil y silenciosa, disfrazándose en la amistad (Prieto, Carrillo y Castellanos, 2016).

La investigación es documental de enfoque cualitativo. Utilizando la metodología de caso, se acompaña de un análisis hermenéutico, al igual que de la aplicación de la entrevista a informantes clave y de la observación directa como instrumentos de recopilación de datos. El método de interpretación fue la triangulación de datos, lo cual generó las reflexiones expuestas.

Las conclusiones, por tanto, establecen nuevas líneas de investigación, ya que en los casos presentados el líder del acto está oculto y utiliza a la mujer como arma para el acoso y destrucción de sus congéneres, lo que sugiere el desarrollo de nuevos patrones de violencia con la finalidad de evadir la normatividad y los protocolos de detección. Asimismo, a partir del análisis de las fuentes se sugiere que, aunado a que es escasa, la poca investigación existente de agresiones alternativas se encuentra escondida en las publicaciones académicas, ya que la cultura machista ridiculiza la agresión de las mujeres como algo poco femenino, oculto y, a consideración de los investigadores, de poco valor.

Published: December 2019

Students' mathematics learning achievement is influenced by many factors, one of which is the learning media used. The textbook is one alternative learning media. The textbook used previously was not focused on problem-solving, so that this development research aims to produce a textbook based on problem-solving in algebra that is valid, effective, and practical. This research uses Gall & Borg development research which is limited to seven steps namely research and information collecting, planning, developing a preliminary form of product, preliminary field testing, main product revisions, main field testing, and dissemination. This research was conducted at the Department of Mathematics Education, Universitas PGRI Madiun. Instruments and data collection used in this study were textbook validation sheets, learning outcomes tests, and student response questionnaire. The results of the research showed that the validation result of the textbook was included in the highly valid criteria (86,74 %), the test results met the criteria of classical completeness (82,75%), and the students' response to the textbook was very high (83,33%). Based on these results, it can be concluded that the algebra textbook based on problem-solving can be used in learning. The results of the application of an algebra textbook based on the problem-solving show an increase in student achievement with an N-Gain value of 0.32.
The Sufficient Conditions for M[[S,w]] to be T[[S,w]]-Noetherian R[[S,w]]-module

In this paper, we investigate the sufficient conditions for T[[S,w]] to be a multiplicative subset of skew generalized power series ring R[[S,w]], where R is a ring, T Í R a multiplicative set, (S,≤) a strictly ordered monoid, and w : S®End(R) a monoid homomorphism. Furthermore, we obtain sufficient conditions for skew generalized power series module M[[S,w]] to be a T[[S,w]]-Noetherian R[[S,w]]-module, where M is an R-module.

Students need an understanding of mathematical concepts provided by educators who have good skills. Educators must also maximize their teaching time so that it requires learning models such as e-learning and blended learning to meet the loss of teaching time due to other activities that must be done by the teacher besides teaching. This study aims to see the impact of blended learning and e-learning on the ability to understand mathematical concepts of students in the material of two-variable linear equations. The method used in this study is the quasi-experiment with the posttest only control design research. Technical analysis uses one way ANOVA. Based on the results of the study, Blended Learning and E-Learning influence understanding mathematical concepts in the two-variable linear equation material, so that it can be used as a knowledge given to students in understanding mathematical concepts.
