Kajian ini bertujuan meneroka kefahaman pelajar Biologi di sebuah kolej matrikulasi terhadap konsep kitar karbon menerusi visualisasi penjanaan kendiri (self-generated visualization). Terdapat empat objektif dalam kajian ini iaitu, meneroka pemprosesan maklumat, mengenal pasti model mental yang terhasil dalam kalangan pelajar berbeza tahap pencapaian, menganalisis kefahaman pelajar mengenai konsep kitar karbon dan seterusnya mencadangkan kerangka instruksi visualisasi penjanaan kendiri terhadap konsep kitar karbon. Reka bentuk kajian yang digunakan adalah Grounded theory. Pensampelan bertujuan digunakan untuk memilih pelajar Biologi tersebut. Data dikumpul dengan menggunakan temu bual mendalam (in-depth interview), tugasan visualisasi kitar karbon dan ujian kefahaman kitar karbon. Data temu bual dan dokumen tugasan dianalisis secara kualitatif dengan menggunakan kaedah perbandingan berterusan (constant comparison method) manakala ujian kefahaman kitar karbon dianalisis dan dilaporkan s.....

Problem Statement: Improper triage and prioritization of big-data patients may result in erroneous strategic decisions. An example of such wrong decision making includes the triage of patients with chronic heart disease to low-priority groups. Incorrect decisions may jeopardize the patients' health. Objective: This study aims to evaluate and score the big data of patients with chronic heart disease and of those who require urgent attention. The assessment is based on multicriteria decision making in a telemedical environment to improve the triage and prioritization processes Methods: A hands-on study was performed. A total of 500 patients with chronic heart disease manifested in di®erent symptoms and under various emergency levels were evaluated on the basis of the following four main measures. An electrocardiogram sensor was used to measure the electrical signals of the contractile activity of the heart over time. A SpO2 sensor was employed to determine the blood oxygen saturation le.....

Preschool teachers? professional development and professional qualifications are crucial in enhancing the quality of children?s education. Studies related to the quality of preschool education and preschool teachers? professional qualifications are very limited in Malaysia. As such, this study embarks on finding the effects of ECCE teachers? professional qualifications on their understanding of overall ECCE training, perceptions of the quality of ECCE training, understanding of ECCE curriculum, and their understanding of the teaching and learning process. This study employed the descriptive research design using questionnaires to collect the data. The sample of the study consists of 296 preschool teachers from West Malaysia. The findings indicate that the ECCE teachers? professional qualifications have a significant effect on their understanding of the ECCE training. The results also show that ECCE teachers with higher professional qualifications have better perceptions of the quality .....

Nationwide health information exchange (NHIE) continues to be a persistent concern for government agencies, despite the many efforts and the conceived benefits of sharing patient data among healthcare providers. Difficulties in ensuring global connectivity, interoperability, and concerns on security have always hampered the government from successfully deploying NHIE. By looking at NHIE from a fresh perspective and bearing in mind the pervasiveness and power of modern mobile platforms, this paper proposes a new approach to NHIE that builds on the notion of consumer-mediated HIE, albeit without the focus on central health record banks. With the growing acceptance of smartphones as reliable, indispensable, and most personal devices, we suggest to leverage the concept of mobile personal health records (PHRs installed on smartphones) to the next level. We envision mPHRs that take the form of distributed storage units for health information, under the full control and direct possession of p.....

The purpose of this study is to evaluate the technological acceptance of Chemistry students, and the opinions of Chemistry lecturers and laboratory assistants towards the use of remote laboratory in Chemistry education. The convergent parallel design mixed method was carried out in this study. The instruments involved were questionnaire and interview protocol. A total of 81 Chemistry students, five Chemistry lecturers and two Chemistry laboratory assistants from Universiti Pendidikan Sultan Idris (UPSI) were chosen as respondents in this study. For the quantitative approach, the data from the questionnaire were analysed using descriptive statistics to evaluate students’ technological acceptance of remote laboratory. For the qualitative approach, the responses from the interviews were analysed to evaluate the lecturers and laboratory assistants’ opinions towards the use of remote laboratory by using coding and grouping methods. Quantitatively, the student respondents had given the m.....

The new and disruptive technology of smart home applications (hereafter referred to as apps) based on Internet of Things (IoT) is largely limited and scattered. To provide valuable insights into technological environments and support researchers, we must understand the available options and gaps in this line of research. Thus, in this study, a review is conducted to map the research landscape into a coherent taxonomy. We conduct a focused search for every article related to (1) smart homes, (2) apps, and (3) IoT in three major databases, namely, Web of Science, ScienceDirect, and IEEE Explore. These databases contain literature focusing on smart home apps using IoT. The final dataset resulting from the classification scheme includes 229 articles divided into four classes. The first class comprises review and survey articles related to smart home IoT applications. The second class includes papers on IoT applications and their use in smart home technology. The third class contains propos.....

In this paper, we have reported an electrochemical detection of metal ions based on Calixarene-based sensor. In the sensing strategy, 3-aminopropylsilane (APTMS) was initially self-assembled on indium tin oxide (ITO) followed by functionalization of dicarboethoxy-calix [4]arene (EtC4). The morphology and properties of electrodes were characterized by contact angle, atomic force microscopy, cyclic voltammetry, electrochemical impedance spectroscopy and X-ray photoelectron spectroscopy. The electrochemical response characteristics of the modified electrodes (EtC4/APTMS/ITO) towards analyte ions; Zn(II), Cu(II), and Fe(II) ions were investigated by differential pulse voltammetry (DPV) under optimized conditions. It was found that the response of modified electrode towards the analytes was improved significantly as compared to the ITO electrode and resulted in limit of detections (LOD) of 9.88 pg/L, 8.33 μg/L and 1.15 μg/L, respectively. In addition, the detection limit of simultaneous d.....

wo novel Schiff Base ligands are used in this work. These amphiphilic ligands were being chosen because of the suitability in forming Langmuir film by using Langmuir-Blodgett (LB) technique. Characterizations of these ligands were carried out through LB technique to obtain the surface pressure-mean molecular area (П-A) and surface potential-mean molecular area (ΔV-A) isotherms. The analysis made from extrapolating the П-A graphs led to the result of the estimated area and the radius of the ligand molecules oriented on the air-water subphase. The UV-Visible spectrometer was used to study the optical properties of the ligands. This study was made in order to recognize the fundamental properties of these ligands for future works on detecting ions applications...
