The surge in global competition necessitates the education system in Malaysia to go through transformation at all aspects, including in the use of technology in Education. The transformation in education towards the 21st Century is not only needed in primary and secondary schools but also in tertiary institutions. The transformation in education leaves a big impact on the field of education, including the teaching of English as Second Language (ESL) which is currently experiencing teaching and learning transformation process as well. This literature review canvasses the advantages of using technology in ESL classroom, the current challenges ESL educators face when teaching ESL in Sabah’s tertiary institutions and the role of ESL educators in using technology in their approach to teaching ESL. This review was carried out through an analysis of secondary data in the form of related and relevant previous studies conducted by researchers in the teaching of English as a second language. The findings indicate that there are some advantages in employing technologies in ESL classrooms. However, there are also few challenges that ESL educators need to embrace or face during teaching ESL in Sabah’s tertiary institutions. ESL educators will serve as a facilitator and guide to assist students in the process of embracing 21st Century learning in Industrial Revolution 4.0 era.

Teaching practicum is an essential part of teacher-training that provides real classroom engagement for a beginner teacher. It is considered as one of the most critical components of teacher preparation with the greatest impact on teacher quality (Mtika, 2011; Zeichner, 2010; Graham, 2006; Tang, 2003) and is significant for the development of their pedagogical skills (Kauffman, 1992). The sudden upsurge of the Covid -19 infections around the world in the first quarter of 2020, witnessed massive closure of schools worldwide in order to contain the spread of the pandemic. This unexpected turn of events had flipped the more traditional face-to-face method of teaching and learning into distance learning that requires 21st. Century technology and skills. This paper explores the experience of a group of trainee teachers from an institute of higher learning in Malaysia, at managing this unprecedented challenge in delivering education remotely via technology. Data were collected from interviews and supplemental written records in the form of lesson plans, teaching evidence, and online tools employed for teaching and learning. The findings show that the trainee teachers undergo varied and often challenging experiences in ensuring the continuity of curriculum-based education and the students’ progress in learning. Their successes in delivering the lessons amidst the novel encounters are the epitome of resilient and flexible teachers in the making.

In this article, a fully 3-D printed embedded passive harmonic sensor tag with improved read range and better clutter rejection is presented for detecting assets located underground. The sensor tag receives the query signal from a 3-D printed Vivaldi antenna at the fundamental frequency (f 0 ) and radiates back to the interrogator at the second harmonic frequency (2f 0 ). The sensor tag consists of a linearly polarized double slot antenna that operates at both the fundamental as well as the second harmonic frequency. Utilizing the capabilities of 3-D printing, a nonlinear diode is embedded onto the substrate and coupled to the antenna for generating the higher order harmonics is designed. The 3-D printed tag is compatible with direct printing onto the buried assets, such as plastic pipelines, as markers for localization. The polarization of the antenna is used for identifying the location and the direction of the pipeline. The sensor tag has higher signal-to-noise ratio and can be readily interrogated with any hand-held readers from above the ground.

This paper demonstrates a simple, low-cost additive manufacturing technique for fabricating structures compatible with high-density packaging solutions. Leveraging the third dimension (z-axis), several out-of-plane (non-planar) antennas that are compatible with multi-layer integration are presented, including an elevated vertical mount patch antenna, an air-gap based E-Patch antenna, a monopole with a corner reflector, and a vertical Yagi-Uda antenna. A T-line resonator is characterized to understand the transmission line losses associated with the vertical bends. Details of the simulation, fabrication, and measurements are presented. Simulations are carried out using ANSYS High-Frequency Structure Simulator (HFSS (R)), and structures are fabricated using a polyjet printing process. The measured results are in good agreement with the simulation results, and overall a good performance is achieved for all the antenna designs. For example, the elevated vertical mount patch shows a gain of 3.62 dBi (center frequency of 5.4 GHz), and the air-gap E-patch antenna shows a gain of 6 dBi at 2.4 GHz and 10 dB bandwidth of 4.9 GHz. The vertical monopole antenna with a corner reflector shows a peak gain of 7.3 dBi at 6 GHz, and the Yagi-Uda antenna shows a forward gain of 6 dBi at 5 GHz.

Trans-radial prosthesis is a wearable device that intends to help amputees under the elbow to replace the function of the missing anatomical segment that resembles an actual human hand. However, there are some challenging aspects faced mainly on the robot hand structural design itself. Improvements are needed as this is closely related to structure efficiency. This paper proposes a robot hand structure with improved features (four-bar linkage mechanism) to overcome the deficiency of using the cable-driven actuated mechanism that leads to less structure durability and inaccurate motion range. Our proposed robot hand structure also took into account the existing design problems such as bulky structure, unindividual actuated finger, incomplete fingers and a lack of finger joints compared to the actual finger in its design. This paper presents the improvements achieved by applying the proposed design such as the use of a four-bar linkage mechanism instead of using the cable-driven mechanism, the size of an average human hand, five-fingers with completed joints where each finger is moved by motor individually, joint protection using a mechanical stopper, detachable finger structure from the palm frame, a structure that has sufficient durability for everyday use and an easy to fabricate structure using 3D printing technology. The four-bar linkage mechanism is the use of the solid linkage that connects the actuator with the structure to allow the structure to move. The durability was investigated using static analysis simulation. The structural details and simulation results were validated through motion capture analysis and load test. The motion analyses towards the 3D printed robot structure show 70-98% similar motion range capability to the designed structure in the CAD software, and it can withstand up to 1.6 kg load in the simulation and the real test. The improved robot hand structure with optimum durability for prosthetic uses was successfully developed.

Since the TV broadcasting was established in Arab countries until the 1990s, broadcasting during this specific time was based on a government control model, which derived from the view of broadcasting as an instrument of state advance that must be under the control from government. This kind of TVs, limits the broadcasting to highlight the government issue (1). In these kind of TVs, they focus with the leader’s opinion more than the Palestinian problem. By the way, the theme in Arab media determined to highlight the leader’s opinion who claims the right to speak on behalf of Palestinians. In September 1991, the first private TV in the Arab world was established when MBC went on the air from London. More private TVs followed after that like: Orbit in 1994 and ART in 1995, both based in Italy owned by Saudi businessmen, Future Television and LBC, both Lebanese based in Beirut, in 1995, and Al-Jazeera based in Qatar in 1996. In 2002 the number of the Arab TV stations was expanded to more than 150 TVS as government or privately owned, with capability of reaching the Arab people in any place in the world. This paper focuses on the media coverage of the conflict between two parties Palestine and Israel. The preview studies show that, in a conflict the media has an influential role and has responsibility for increasing violence or contributing to the resolution of conflict and mitigation of violence (2). This study examined 61 news coverage and framing of the Israel and Palestine conflict, known as the 50 days’ war from 8 July – 26 August 2014 by Ma’an News Agency, which delivers news to Ma’an TV (Palestinian satellite television station). A quantitative content analysis was employed to examine the news published during the war using five generic frames developed by (3). Holsti Inter-coder reliability and validity test value is 0.988 or 98% agreement. The results showed that conflict and human-interest frames were significantly visible compared to other frames in Ma’an news coverage. Portrayal of images of civilian killing, children and women killed in their homes and suffrage news coverage, in this war. Responsibility frame stressed on hospitals bombing and embargo of medications which reduced chances for Palestinian of immediate medical help. The economic frame highlighted the economic and financial losses of Palestinians as consequences of 50 days’ war. Most of them lost their income, businesses, agriculture land and homes and became refugees.

Our consciousness is somewhat shaped by our surroundings. External and internal consciousness can guide, explain, direct, and train us to form our socio-cultural belief systems. These socio-cultural belief systems may partly explain why we do what we do, why we see what we see, why we say what we say, and why we feel what we feel. Our consciousness, to a large extent, shapes and energizes our understanding of human beings� complex relations. As such, 9/11 strife-torn unrests, for example, leaves behind unnecessary complications, chaos, and risks, not only to many Americans, but also to other Islamic nation-states. These sporadic and unpredictable 9/11 complexities are not only discussed, debated, and negated, but has also contributed to our awareness on what it means to live in the post-9/11 era. While many of these explorations are affirmed, regarded, and profound in many Western nation-states, studies on 9/11 consciousness from Asian perspectives, particularly from the viewpoints of Muslim-dominated nations are, to this end, largely insufficient. Taking these contours into consideration, this paper attempts to discuss the extent to which 9/11 consciousness are highlighted in newspapers. Specifically, using spectrum of consciousness theory, this paper explores some of the many ways consciousness of 9/11 tensions is framed in five Malaysian newspapers. We will show the ways in which newspapers describe 9/11 contexts and how diverse layers of consciousness are delineated in the newspaper, forming some levels of questions, contests, and negotiations about 9/11 chaos. The discourse analysis included in this study will demonstrate different fragments of 9/11 reality. By describing these constructions of 9/11 in newspapers framed within spectrum of consciousness, we will be able to reveal the dynamics of these unsettled, unruly 9/11 complications.

Smart wearables have gained considerable attention from Information Systems (IS) academics, business managers, and health practitioners. In spite of the availability of authentic research studies of smart wearables, there is still a lack of systematic review on the different aspects of smart wearables concept to find the current state of research, particularly from the perspective of IS field. Therefore, the predominant aim of this research is to review smart wearables literature, recent advances, and future challenges. Accordingly, a systematic literature review was conducted to explore smart wearables by reviewing previous studies from 2010 to 2019. For covering all related papers during these years, an integrated review protocol consisting of automatic and manual stages was pursued. 244 papers were identified to address smart wearables issues and challenges. According to the findings, it is observed that smart wearable studies have increased dramatically during the last years. Moreover, the results show that current studies covered different research themes which are related to smart wearables area, particularly user behavior, technology-focused, security and privacy, design, and social acceptability. Furthermore, based on the results of the weight analysis technique, perceived usefulness, attitude toward technology, social influence, and privacy concerns are identified as the best predictors of smart wearables adoption. Additionally, the results show that the Technology Acceptance Model (TAM) is the most commonly adopted theory in the smart wearable studies. The findings of this review would assist academics to realize the existing limitations and gaps as well as the future works for smart wearables research studies.

The window of maximum susceptibility for the development of dental fluorosis for anterior teeth is during the first two to three years of life. The primary source of fluoride intake for infants at this age is mainly from the diet including infant formula. Thus, the present work aimed to investigate the fluoride concentration in commercially available Malaysian infant formulas that required reconstitution before consumption. A total of 29 infant formulas available in the Malaysian market were reconstituted with deionised water, fluoridated tap water, and filtered tap water. The fluoride concentration of the infant formulas was analysed directly using a fluoride ion selective electrode. The daily fluoride intake estimation from the infant formulas was calculated using the median infant body weight and recommended volumes for formula consumption from newborn to > 12 months of age. Results showed that the fluoride concentration of the infant formulas when reconstituted with deionised water ranged between 0.009 to 0.197 mg/L that contributed to the estimated daily fluoride intake ranging from 0.005 to 0.100 mg (total intake per day) or 0.001 to 0.025 mg/kg (total intake per body weight/day). The fluoride concentration in the selected infant formulas was low, but after reconstitution with fluoridated tap water, the overall fluoride concentration in infant formulas sample significantly increased (p < 0.001). Nevertheless, the estimated daily fluoride intake from infant formulas alone did not exceed the lowest-observed-adverse-effect level (LOAEL) of fluoride at 0.10 mg/kg/day.

A Quasi Z-Source (qZS) network has been utilized in a B4 inverter topology to provide voltage boosting effect by turning on the upper and lower switches simultaneously which is known as zero shoot-through states. However, the design of a qZS B4 inverter is not as straightforward as adding a qZS LC impedance network to the front-end of a B4 inverter. This is because there are no zero vectors available in a B4 inverter topology to insert the shoot through zero states, as in the case of a B6 inverter. This paper proposes a new Space Vector Modulation (SVM) technique for a qZS B4 inverter. Additional zero vectors have been appropriately added and distributed in the proposed SVM to avoid altering the existing volt-sec per switching cycle for the existing active vectors. The voltage vectors switching placement is carefully designed in order to enable the voltage boosting effect for this topology without altering the initial output voltage. In addition, an approach to compensate the DC-link voltage ripple has also been taken into consideration in its initial calculation to achieve balanced output voltage. The performance of the proposed modulation technique is verified using MATLAB/Simulink. It is shown that by using the proposed modulation technique, there is an overall improvement on the line to line output voltage where by it is able to produce balanced output voltages for the three-phase loads with or without boosting effect. � 2020, Institute of Advanced Engineering and Science.

Android mobile devices are used for various applications. Online banking and shopping are increasingly being performed on smartphones. As the role of smartphones in business grows, the floodgates have opened mobile devices to malware threats, which can be exploited for malicious purposes. Mobile malware is growing in sophistication and continues to target consumers. Consumers are charged without affirmative consent. As a solution to this challenge, we proposed a system call classification based on surveillance exploitation system calls for SMS. The proposed system calls classification is evaluated and tested using applications from Google Play Store. This research focuses on Android operating system. The experiment was conducted using Drebin dataset which contains 5560 malware applications. Dynamic analysis was used to extract the system calls from each application in a controlled lab environment. This research has developed a new mobile malware classification for Android smartphone using a covering algorithm. The classification has been evaluated in 500 applications and 126 applications have been identified to contain malware. � 2017 American Scientific Publishers All rights reserved.

One of the major problems in the analysis of ammonia (NH3) using spectrophotometric method is highly coloured water sample. A reflectometric NH3 sensor based on a facile single-step immobilisation of cobalt(II) (Co2+) ion onto high capacity Dowex HCR-W2 microspheres has been developed to enable the direct NH3 determination in highly coloured water samples. The combination of Co2+ ion-immobilised microspheres via cation exchange chemical reaction and reflectometric technique has improved the optode sensing performance with respect to linear response range and response time. Immobilised Co2+ ion, when complexed with NH3 gave a blue colouration of hexamminecobaltate(II) ([Co(NH3)(6)](2+)) complex at pH 13. The NH3 sensor reached maximum colour intensity in similar to 6 min at ambient conditions. The linear calibration curve was 60-290 mM NH3 with a detection limit of 16 mM NH3, which is suitable for direct determination of NH3-enriched leachate water samples. A good reproducibility between 5.4 and 5.9% relative standard deviation (RSD) was obtained with the probe and the sensing performance can be regenerated using buffer pH 1. The effect of potential interference ions has been investigated during the quantification of NH3 in heavily polluted sewage water. The results obtained were in good agreement with those produced by acidimetric reference method. Crown Copyright (C) 2012 Published by Elsevier B.V. All rights reserved.

Nowadays, search engines tend to use latest technologies in enhancing the personalization of web searches, which leads to better understanding of user requirements. This paper aims to address the problem of enhancing the efficiency of search system by mining data logs. Search logs are associated with all the interactions that have been done between the user and the search engine including the query, the resulted pages and the selection. The paper also aims minimize the ambiguity within the query whilst the partitioning-based clustering aims to reduce the search space by dividing the data into groups that contain similar objects. To do so, this paper conduct several experiments to evaluate correlation clustering method. The method of this paper includes a pre-processing phase, which in turn involves tokenization, stop-words removal, and stemming. In addition, we evaluates the impact of the two similarity/distance measures (Cosine similarity and Jaccard coefficient) on the results of the correlation clustering method. Experimental results obtained are quite satisfactory in terms of the Precision, Recall and F-score. � 2005-2016 JATIT & LLS. All rights reserved.

An epistemological model of learning fields of probabilistic events is formalized. It is used to explain resource allocation that is governed by pervasive complementarities as the sign of unity of knowledge that is induced epistemologically into interacting, integrating and evolutionary variables representing the problem at hand. The end result is formalization of a probabilistic model of learning that has no optimal points. In it variables and their representations simply learn continuously and generate evolutionary general equilibrium points. Such points can be computed by computational general equilibrium under the impact of learning in unity of knowledge. Of all approaches 10 such a study only the doctrine of the paired universe of the Qur'an stands out as unique. In this regard the Qur'an says (36:36), "Glory to God, Who created in pairs all things that the earth produces, as well as their own kind and things of which they have no knowledge."Upon the episteme of unity is constructed the probabilistic model of learning fields. In it we refer to the specific issue of money-real economy linkages as a resource mobilization problem involving an asset valuation approach. Some empirical evidence is placed in respect of the consequences expected from the study of probabilistic models of learning fields applied to economic and financial problems.

Many governments today have implemented Electronic Document Management Systems (EDMS). The employment of EDMS systems has increased the operational (e.g. document storage and retrieval, auditing, workflow facilities, searching and publishing) effectiveness of governments on daily basis. However, not many studies had been undertaken into process of implementing EDMS in the government context. Therefore, this paper fills this gap by presenting a research framework for the implementation process of EDMS. Based on a content analysis of the reviewed literature, this paper identifies thirteen (13) common factors contributing to the implementation process of EDMS. The factors are: (1) Top management support; (2) Budgetary; (3) Implementation planning; (4) Anti-corruption; (5) Implementation staff; (6) Security and privacy; (7) Data quality, (8) User requirements; (9) Cooperation; (10) Systems integration; (11) Awareness; (12) Resistance to change; and (13) Staff training. All these factors subsequently were linked to the Prosci-ADKAR model of change to outline the structure of EDMS implementation process framework. The proposed framework contributes to the theoretical understanding of the EAI implementation process, which may support government practitioners in implementing the EDMS applications in their government organizations. The paper also highlights with three important issues that need to be explored further while developing the framework: 1) the EDMS implementation process meaning in system development life cycle; 2) the importance of EDMS implementation factors; and 3) the kind approach to investigate EDMS implementation process. � 2005 - 2015 JATIT & LLS.
