Published: November 2020

The research concerned the application of Dynamic Assessment (DA) in English Language Teaching (ELT) which based on Vygotsky’s theory, namely Zone of Proximal Development (ZPD). The research was meant to investigate the effect of DA in improving teaching and learning speaking in Indonesia especially English as a Foreign Language (EFL) learners in university. The research was conducted using a qualitative method by involving four Indonesian university learners in the first semester. The participants received the same treatments through pre-test and self-reflection, feedback and knowledge expansion, post-test and self-reflection, post-feedback, and semi-structured interviews. The instruments were used to analyze the learners’ non-fluency and mastery problem. The analysis showed that the learners’ speaking performance was improved after experiencing DA sessions. The results of the test and self-reflection showed significant improvement in their speaking. The finding showed some positive effects of DA on EFL learners’ speaking performance. In interviews, learners showed positive experiences and attitude toward DA since it served them a comfortable, structured, practical, and meaningful platform to recognize their speaking behavior, weaknesses, strength, and needs. Furthermore, it also helped them to get the objective feedbacks with less anxiety. The researchers conclude that DA can be applied as a primary alternative assessment in English speaking practices.

Published: November 2020

The main purpose of this study was to design and verify the quality of an assessment aimed at diagnosing scientific misconceptions among students enrolled in 10th-grade biology subjects. A sample consisted of N=200 students from schools under the administration of the Office of Secondary Educational Service 31, Nakhon Ratchasima province. We employed the design-based approach, which consists of four phases, namely, construct map, item design, outcome space, and Wright map. Multidimensional Random Coefficient Multinomial Logit Model (MRCMLM) was used to evaluate the quality of the assessment tool. The assessment tool consists of two dimensions, namely, knowledge and reasoning. The assessment tool is comprised of 40 items, with 20 items tapping each of the dimensions. Findings form item analysis and modeling revealed sufficient evidence on the internal structure and validity of the instrument. It can be concluded that the unidimensional model is more appropriate than the multidimensional model for diagnosing scientific misconceptions in the genetics topic for dichotomously scored with four options in each item. The polytomous scored type should be further investigated to determine the best fit model in the items relating to evidence-based reasoning for supporting students’ answers.

Published: November 2020

Teacher education institutions (TEIs) in the Philippines establish their brand of educational quality through their graduates’ performance in the Licensure Examination for Teachers (LET). It is, therefore, necessary for TEIs to align instructional delivery with the competencies in the LET. Thus, this study was undertaken to correlate academic achievement and licensure examination performance of teacher education graduates. Academic achievement is the graduates’ grade weighted average in college and pre-board examination results. The respondents were 1,017 graduates of Bachelor of Secondary Education and Bachelor of Elementary Education in a state university in Cagayan Province, Philippines. The study revealed a significant and strong correlation between the graduates’ grade weighted average in college and LET performance. This is an indication of the effective evaluation procedure of the university since the teachers’ assessment concurs with the graduates’ performance in the LET. A significant relationship was also established between the graduates’ performance in the pre board examination and LET albeit with a weak correlation. This study recommends the development of mechanisms in improving the conduct of pre-board examination review programs in the university. Further validation of the assessment tools used in the pre-board examination is likewise suggested.

Published: November 2020

Academic reading is an inescapable task in higher education. Due to its importance for study success, students are required to maintain their academic reading engagement. With engagement, they would be enabled to persevere and be more spirited in their reading efforts. However, not all students perceive academic reading positively, particularly in EFL learning environment where English reading is seen as something daunting. Academic reading engagement is essentially determined by a number of dimensions, one of which is affective dimension. This research aims to portray the affective dimension of the academic reading engagement among student teachers of English as a Foreign Language (EFL) in a teacher-training university in Indonesia. Eight EFL student teachers were selected from three classes of an English content course which required a lot of academic reading. These student teachers were interviewed using a semi-structured guide. The results show that many EFL student teachers’ efforts in coping with course-related reading materials were externally driven. They showed low liking for learning, demonstrated little enthusiasm, interest, enjoyment, and confidence in relation to academic reading. Also, they did not always understand the values of academic reading and text relevance for their development as teachers.

The spread of the COVID-19 coronavirus occurs in all countries. This pandemic incident has been taken seriously by various sectors including in the world of education. This research is a quantitative descriptive study to explain the Self-Regulated Learning (SRL) profile of Indonesian students in online learning which is carried out in COVID-19 emergencies. The research commenced three days after the establishment of the WHO COVID-19 pandemic. The respondents were taken by accident sampling at several schools implementing online learning after the designation of this mode by the Indonesian Ministry of Education and Culture on March 15, 2020. The schools comprised general high schools and vocational schools. The data were collected via Google Form filled out by 10th to 12th-grade students. The instrument used was a questionnaire with a scale of 1 to 5 (from absolutely disagree to absolutely agree) consisting of planning, monitoring, controlling, and reflecting aspects. There were two analytical techniques used i.e., descriptive statistics and ANOVA. The results of this study indicate that students in Indonesia still need assistance and mentoring from teachers to improve SRL. Several mentoring strategies can be applied to manage active learning. The teachers should explicitly include the process of mentoring, strengthening the students’ SRL. Teachers need to be aware that online learning is not only to master certain subject matters but also to strengthen SRL.
The responsiveness of Bachelor of Elementary Education curriculum: An illuminative evaluation
Authors: Cahapay Michael Bobias
Published: November 2020

As higher education institutions are pressured to evaluate the responsiveness of their curriculum programs, there is a challenge of first order to define responsiveness. This challenge, however, is compounded by the paucity of a tested evaluation model that addresses it. Thus, this paper aimed to evaluate the responsiveness of the Bachelor of Elementary Education curriculum by attempting the applicability of the model called “illuminative evaluation.” Following the stages and components within the social anthropological framework of the model, multiple methods such as interviews, document reviews, and surveys were employed. The main data analysis technique used was the thematic analysis. The results revealed that illuminative evaluation contextually defined the concept of responsiveness and it effectively uncovered concealed aspects that indicate discrepancies within the curriculum. Thus, given these research outcomes, this work contributes new knowledge to the tradition of evaluation theory and provides practical evidence for the improvement of the curriculum under evaluation. The recommendations are offered at the end of the study.

Social comparison and life satisfaction in social media: The role of mattering and state self-esteem
Authors: P. T. Sim Patrick , Prihadi Kususanto Ditto
Published: November 2020

The overarching aim of this study is to explain how comparing self to others in social media might predict one’s sense of life satisfaction. In order to achieve that, we test the hypothesis that mattering and state self-esteem play a serial mediation that explains the link between social comparison in social media and life satisfaction. One hundred and forty-seven participants’ ages between 18 to 35 were recruited to participate in this research and were asked to fill up the Iowa-Netherlands Comparison Orientation Measure, General Mattering Scale, State Self-Esteem Scale and Riverside Life Satisfaction Scale questionnaires. Bias-free Bootstrap Method with 5000 sample has been conducted to analyze the relationship among the variables, and the results suggested that the overall model of the predictor significantly contributed to life satisfaction. Nevertheless, because social comparison did not predict the sense of mattering, serial mediation did not occur as per hypothesized. Our supplementary analyses indicated that state self-esteem fully mediated the contribution of mattering on life satisfaction. Implication, limitation and suggestions are discussed at the end of the paper.

Published: November 2020

The application of robot simulation tools for modelling, analysis and improvement of existing industrial manufacturing cells is presented with reference to the development and implementation of the digital factory concept. A real case study of aerosol can packaging and palletizing cell scenario in the metal can manufacturing industry for containing food and products is used as a reference in this paper. For studying manual aerosol can packaging and palletizing conditions of the worker, a detailed time and motion analysis of workers is carried out. On the basis of cycle time analysis results, an alternative to the manual operation, a more sophisticated automated packaging and palletizing system is suggested. A proposed system which uses a robotic manipulator including automated production machine and devices are also developed and tested. The viability of the suggested system is checked through simulation and cycle time analysis. A fuzzy logic software, MATLAB is employed in order to analyse the actual system’s behaviour in terms of productivity, and utilization of the available facilities. The 3D simulation software, DELMIA V6  is additionally employed to perform a detailed design phase of the manufacturing cell. From the simulation results, this gives a rough approximation that the production of one robotized manipulator, and automated packaging and palletizing cell is equal to the production of about 4.3 manual packaging and palletizing cells. These results have shown the need for change to automation in the aerosol can packaging and palletizing system.
Air cloud algorithm for diminution of active power loss
Authors: Lenin Kanagasabai
Published: November 2020

In this work, air cloud (AC) algorithm is used to solve the optimal reactive power problem. Clouds shape in numerous ways. Convective clouds are created when moist air is warmed and expand into floating. Air raises haulage water vapour and within it expands and gets cooled as it goes. As the temperature and pressure of the air diminish, its saturation point – the equilibrium level of evaporation and condensation – is reduced. Every x is one cloud droplet, and qualitative characteristic of one cloud is explained by the three digital character (Ex, En, He), droplets number n, where Ex (Expected value), En (Entropy) and He (Hyper entropy) of one cloud determine centre position of cloud, cover range of cloud and thickness of cloud equally. Projected AC algorithm has been tested in standard IEEE 14, 57, 300 bus systems and simulations results show the better performance of the proposed algorithm in reducing the real power loss.
Emotional model for a multi-robot system with emergent behavior
Authors: Gil Angel , Aguilar Jose , Dapena Eladio , Rivas Rafael
Published: November 2020

This article describes an emotional model for a general-purpose robot operating in a multi-robot system with emergent behavior. The model considers four basic emotions: anger, rejection, sadness and joy, plus  a neutral emotional state, which affect the behavior of the robot,  both individually and collectively. The emotional state of each robot in  the system is constructed through the conjunction of a series of factors related to their individual and collective actions, which are: safety, load, acting and interaction, which serve as input to an emotional process that results in an index of satisfaction of the robot that establishes the emotional state in which it is in a certain moment. The emotional state of a robot influences its interactions with the other robots and with the environment, that is, it determines its emergent behavior in the system. This paper  presents the design of this model, and establishes some considerations for its implementation.

Power transmission lines are of great importance for the operation of all sectors of society, such as commerce, industry and public agencies. To ensure reliability and availability of power supply, regular and occasional inspections are conducted, mostly using patrol with binoculars, helicopters or truck cranes. Research is being developed using unmanned aerial vehicle (UAV) to make this activity autonomous, faster, safer, and less costly. The present work aims to analyze research related to the autonomous control of the UAV along the transmission lines through a systematic review of the literature (SRL), apply a viable solution and to verify the possible lacuna in this state of the art. Improvements in safety, computational process and energy efficiency with low-cost were identified. The results presented can help the research community to perform the working this state of art, from the suggestions of autonomous tracking of transmission lines.

Low power consumption is the necessity for the integrated circuit design in CMOS technology of nanometerscale. Recent research proves that to achieve low power dissipation, implementation of approximate designs is the best design when compared to accurate designs. In most of the multimedia ap- plications, DSP blocks has been used as the core blocks. Most of the video and image processing algorithms implemented by these DSP blocks, where result will be in the form of image or video for human observing. As human sense of observation isless, the output of the DSP blocks allows being numerically approx- imate instead of being accurate. The concession on numerical exactness allows proposing approximate analysis. In this project approximate adders, approximate compressors and multipliers are proposed. Two approximate adders namely PA1 and PA2 are proposed which are of type TGA which provides better results like PA1 comprises of 14 transistors and 2 error distance, achieves reduction in delay by 64.9 % and reduction in power by 74.33% whereas the TGA1 had 16 transistors and more power dissipation.PA2 comprises of 20 transistors and 2 error distance. Similarly PA2 achieves delay reduction by 51.43%, power gets reduced by 67.2%. PDP is reduced by 61.97 % whereas TGA2 had 22 transistors. Approximate 4-2 compressor was proposed in this project to reduce number of partial produt. The compressor design in circuit level took 30 transistors with 4 errors out of 16 combinations whereas existing compressor design 1took 38 and design 2 took 36 transistors. By using the proposed adder and compressors, approximate 4x4 multiplier is proposed. The proposed multiplier achieves delay 124.56 (ns) and power 29.332 (uW)which is reduced by 68.01% in terms of delay and 95.97 % in terms of power when compared to accurate multiplier.

This paper presents an implementation of Space-time Trellis Codes for 4-state on FPGA. To reach the very high data rates provided in STTC, a lot of expensive high-speed Digital Signal Processors (DSPs) should be employed for the real time applications, while it might not be affordable. This fact has motivated in designing dedicated hardware implementations using Field Programmable Gate Array (FPGA) with low cost and power consumption. The hardware device XC3S400, family Xilinx Spartan-3, and package PQ208 are used in this project, in which the STTC encoder and decoder utilizes maximum 10% and 22% as that of available device capacity respectively. The design has been simulated and synthesized successfully in Xilinx integrated software environment.
Efficient adaptation of the Karatsuba algorithm for implementing on FPGA very large scale multipliers for cryptographic algorithms
Authors: Andre Walder
Published: November 2020

Here, we present a modified version of the Karatsuba algorithm to facilitate the FPGA-based implementation of three signed multipliers: 32-bit × 32-bit, 128-bit x 128-bit, and 512-bit × 512-bit. We also implement the conventional 32-bit × 32-bit multiplier for comparative purposes. The Karatsuba algorithm is preferable for multiplications with very large operands such as 64-bit × 64-bit, 128-bit × 128-bit, 256-bit × 256-bit, 512-bit × 512-bit multipliers and up. Experimental results show that the Karatsuba multiplier uses less hardware in the FPGA compared to the conventional multiplier. The Xilinx xc7k325tfbg900 FPGA using the Genesis 2 development board is used to implement the proposed scheme. The results obtained are promising for applications that require rapid implementation and reconfiguration of cryptographic algorithms.Here, we present a modified version of the Karatsuba algorithm to facilitate the FPGA-based implementation of three signed multipliers: 32-bit × 32-bit, 128-bit x 128-bit, and 512-bit × 512-bit.

Background

Aortic stenosis (AS) is one of the most common forms of valvular heart disease. Our aim was to estimate the burden of AS in the hospital in France, describe patient characteristics, and evaluate the mortality rate and temporal trends.

Methods and Results

All patients hospitalized for AS in France between 2006 and 2016 were identified from the national hospital discharge database. Patients’ sociodemographic, medical, and surgical characteristics and temporal trends were described. All AS‐related deaths between 2000 and 2014 were identified using death certificates. In 2016, 26 071 patients were hospitalized for AS: 56.5% were men with an average age of 77 years. The all‐cause mortality rate at 1 year postindex stay was 11%. The rate of patients hospitalized for AS increased by 59% between 2006 and 2016, reaching 38.7/100 000 person‐years in 2016. This increase was most pronounced in patients aged >75 years. The number of transcatheter aortic valve implantations increased following their introduction in 2010. In 2016, 44% of patients were treated with aortic valve surgery during the index hospital stay or following year (mean age, 71.5 years), and 34% were treated with transcatheter aortic valve implantation (mean age, 83.0 years). In 2014, 6186 deaths caused by AS were identified in death certificates: 41.6% were men with an average age of 87 years. The age‐standardized mortality rate increased by 5% between 2000 and 2014, reaching 8.5/100 000 person‐years in 2014.

Conclusions

The rate of patients hospitalized for AS increased in recent years in line with the higher life expectancy and introduction of transcatheter aortic valve implantation. Mortality increased more moderately.
