Developing an E-Portfolio Model for Malaysian Skills Certification

The rapid development of ICT nowadays demands that the vocational education system in Malaysia needs to change for improvement in the quality of technology-based learning systems. The Malaysia Skills Certification (MSC) E-portfolio model was developed in this study to improve the existing portfolio used for MSC purposes. This study was conducted to verify the MSC E-portfolio measurement model. Respondents involved in this study were 350 MSC instructors from Institute of Public Skills Training in Malaysia, where 200 respondents were selected from institution under the Ministry of Human Resources and 150 respondents were under the Ministry of Youth and Sports in Malaysia. The total size of the respondent is based on the sample size formula of Krejcie and Morgan and the sample was determined using a stratified random sampling method. A questionnaire was used to obtain the research data. Rasch measurement model approach using Winsteps software was used to carry out questionnaire checks in terms of reliability and the validity of the instrument. Verification of content validity and reliability is done by 7 experts through a modified Delphi method. All 38 indicators that measure the MSC E-portfolio elements have high reliability and validity based on internal consistency analysis, indicator reliability, convergent validity and discriminant validity. This shows that a combination of all these four elements can produce an E - portfolio system that is more systematic and multi-purpose, as the concept of e-portfolios are still least applied in the education system. Overall, it can be concluded that the E-portfolio MSC constructs influenced by four major factors which are, operating systems, assessment of competence, Recognition of Prior Achievement (RPA) and virtual learning space. This study also directly gives a new dimension to the MSC system from the aspect of student competency assessment, interactive learning, safety safer storage of learning materials and provide a more systematic knowledge management space

AutoLog: A Log Sequence Synthesis Framework for Anomaly Detection

The rapid progress of modern computing systems has led to a growing interest in informative run-time logs. Various log-based anomaly detection techniques have been proposed to ensure software reliability. However, their implementation in the industry has been limited due to the lack of high-quality public log resources as training datasets. While some log datasets are available for anomaly detection, they suffer from limitations in (1) comprehensiveness of log events; (2) scalability over diverse systems; and (3) flexibility of log utility. To address these limitations, we propose AutoLog, the first automated log generation methodology for anomaly detection. AutoLog uses program analysis to generate run-time log sequences without actually running the system. AutoLog starts with probing comprehensive logging statements associated with the call graphs of an application. Then, it constructs execution graphs for each method after pruning the call graphs to find log-related execution paths in a scalable manner. Finally, AutoLog propagates the anomaly label to each acquired execution path based on human knowledge. It generates flexible log sequences by walking along the log execution paths with controllable parameters. Experiments on 50 popular Java projects show that AutoLog acquires significantly more (9x-58x) log events than existing log datasets from the same system, and generates log messages much faster (15x) with a single machine than existing passive data collection approaches. We hope AutoLog can facilitate the benchmarking and adoption of automated log analysis techniques.Comment: The paper has been accepted by ASE 2023 (Research Track

Development of the Integrated Model of the Automotive Product Quality Assessment

Issues on building an integrated model of the automotive product quality assessment are studied herein basing on widely applicable methods and models of the quality assessment. A conceptual model of the automotive product quality system meeting customer requirements has been developed. Typical characteristics of modern industrial production are an increase in the production dynamism that determines the product properties; a continuous increase in the volume of information required for decision-making, an increased role of knowledge and high technologies implementing absolutely new scientific and technical ideas. To solve the problem of increasing the automotive product quality, a conceptual structural and hierarchical model is offered to ensure its quality as a closed system with feedback between the regulatory, manufacturing, and information modules, responsible for formation of the product quality at all stages of its life cycle. The three module model of the system of the industrial product quality assurance is considered to be universal and to give the opportunity to explore processes of any complexity while solving theoretical and practical problems of the quality assessment and prediction for products for various purposes, including automotive

Computerized Management Information Systems Resources and their Relationship to the Development of Performance in the Electricity Distribution Company in Gaza

This paper aims to identify computerized management information systems resources and their relationship to the development of performance in the Electricity Distribution Company in Gaza. This research used two dimensions. The first dimension is computerized management information systems and the second dimension the Development of Performance. The control sample was (063). (360) questioners were distributed and (306) were retrieved back with a percentage of (85%). Several statistical tools were used for data analysis and hypotheses testing, including reliability correlation using Cronbach’s alpha, “ANOVA”, Simple Linear Regression and Step Wise Regression. The overall findings of the current study suggested the presence of a statistically significant relationship between resources (physical, software, and human and organizational) for the computerized management information systems and the development of performance in the Electricity Distribution Company in Gaza. The study recommended the following: The need to strengthen the company's management interest in the potential of computerized management information systems and using them in the computerization of all the company's activities. And the need to involve workers and users in the design of computerized management information systems and assessment and development process. And strengthen the relationship between users and information systems personnel in the department responsible for the system. And it is essential that the company is developing the infrastructure for information technology in general, and computerized management information systems, in particular for the development of performance. And increase interest in providing resources (physical, software, and human and organizational) for the computerized management information systems. The current study is unique by the virtue of its nature, scope and way of implied investigation, as it is the first study at Electricity Distribution Company in Gaza resources explores the status of Computerized management information systems and their relationship to the development of performance in the Electricity Distribution Company in Gaza increasing interest in Computerized management information systems through continuity, keeping pace with technological means and modern techniques
