    Today's dynamic development trend and competitive ICT era have seen drastic dependence on ICT usage and services. It drives organization towards improving the performance of its ICT services (ICTS). This is achievable by focusing on the organization's ICT mission and vision which depends on seamless coordination, effective monitoring and continuous action that only accessible through consistent governance of ICTS. It is important for the ICT services quality (ICTSQ) and achieving business aim and objectives. However, nowadays, most firms' governance process is ad-hoc and informal, no enterprise wide consistency and accountability weakness without formal approach to govern the complexity of ICTS. To address this issue, the study tries to reveal the governance components to be considered for ICTSQ by focusing on Higher Education Institutions (HEIs) since ICT and their services play an important role in the context of universities. Besides focusing on universities' core activities of teaching and learning, it also promotes technology development of the country. ICTS requires the governance component to ensure feasible and orderly function of planning, implementation, coordination and monitoring. Some previous general governance framework and IT governance developed by various organizations such as International Organization for Standardization (ISO), IT Infrastructure Library (lTIL) and Control Objectives for Information and related Technology (COB IT) have been reviewed, Hence, the reviews outcome and preliminary interviews are fundamental in understanding the governance of ICT services in the listing of governance component appropriate for ICTSQ within HEIs context. Ideas and guidelines from the findings should be useable for the relevant parties' assesment, measurement and improvement of their ICTS

    Software or application testing is a process of executing a program with the goal of finding defect to make better system. In software testing phase, writing test cases is one of the important activities. Manually writing test cases approach is lengthy of time period and need more effort to accomplish the process. On the other hand, automated test case generation technique is the way to solve this issue and model-based test case generation approach would be the appropriate for this automation process. Usually, a model is required in model-based testing approach to generate the test cases and UML activity diagram is the model in our research. In this paper, we explained our proposed model-based test case generating approach and we successfully developed a tool based on our proposed technique that could generate test cases automatically using UML activity diagram as an input. Finally, we conducted an experiment on a real life simple application of a system using the tool and successfully able to show that our tool can produce same test cases as manually writing test cases of the same system but this tool can save a lot of time and effort as well

    {0, 1, 3}-NAF representation and algorithms for lightweight elliptic curve cryptosystem in Lopez Dahab model

    Elliptic curve scalar multiplications is the most time-consuming and costly operation in elliptic curve cryptosystem. The scalar multiplication involves computation of Q = kP where k is a scalar multiplier, and P and Q are points on an elliptic curve. This computation can be improved by reducing the Hamming weight of the scalar multiplier k. The Hamming weight of k represents the number of nonzero digits in the scalar multiplier. This paper proposes a new scalar representation in non-adjacent form (NAF) using the digits 0, 1 and 3. This paper also proposes an algorithm for converting from a binary to {0,1,3}-NAF representation. Comparative analysis between the proposed NAF and the traditional NAF with digit {-1,0,1} is carried out. At average case, the proposes {0,1,3}-NAF representation has a lower Hamming weight than the traditional NAF. In our analysis, we use the {0,1,3}-NAF representation in the scalar multiplication operation. The average number of point addition operations in the scalar multiplication is considerably reduced compared to the addition-subtraction scalar multiplication algorithm

    Nowadays most of the public sector organisations are implementing a knowledge management system (KMS) to assist the systematic creation and sharing of their knowledge resources. The recent technological needs, collaboration and cooperation among public sector organisations (PSO) serve a vital role in the development of knowledge management systems (KMS). However, in order to establish a successful and standardised collaborative KMS amongst Malaysian PSO (MPSO), proper governance needs to be in place. The aim of this study is to identify governance components for collaborative KMS (CKMS). Accordingly, the journal articles published within the period 1998-2013 were identified and analysed. The articles were sourced mainly from Knowledge Management Research & Practice, Science Direct, Emerald, MIS Quarterly, as well as from some other academic databases. Keywords used during the literature search were “governance”, “knowledge management system”, “collaboration”, “collaborative knowledge management system”, “knowledge sharing” and “knowledge management governance”. Moreover, expert opinion from the public sector expert teams and academic experts was also acquired from several consultation sessions to ensure that the components obtained from the readings meet the requirements of KMS collaborations. Based on the analysis and consultation, a conceptual model for governance of CKMS is constructed

    Software development process and software quality have important roles in government and education sector as our society nowadays becomes more dependent on computers technology especially in system or software product development. Thus, the effectiveness of project management is an important factor to find out the achievement of the software development processes as well as level of software quality. Previously, a research studies regarding the practices of software development process have been conducted by many researchers to examine the effectiveness of the practices including research studies were conducted in European countries, India, Japan and just a few in Asian countries especially in Malaysia. With regard of this situation, this research study conduct a survey in order to investigate current practices of software development process activities as well as identifies the methodology, programming languages and techniques used in software development processes. The structured questionnaire have been distributed to the respective respondents for data collection followed by data extracting, data analyzing, evaluation and discussion of the results. Basic statistical methods which are frequency and cross tabulations were used to analyze the data. The results of this research study have addressed some important points regarding the practices of software development processes used in government and education sectors in Malaysia such as gives impact towards a better quality of software or system. Furthermore, implementing of project management process are not in maximum approach which show that project management are not fully implemented in development of a project

    Get PDF
    Social commerce is a relatively new stream mediated by the proliferation of Social Networking Sites (SNSs) and the popularity of social media. The social commerce wave has opened up vast opportunities in emerging markets through online communities’ participation. Knowledge sharing and learning through online communities are made possible with the active collaboration and interaction among groups of individuals. This study investigates on the role of social media in facilitating online communication of consumers through related theories and constructs, leading to online social support. A conceptual model integrating constructs of the Theory of Planned Behavior (TPB), Social Support Theory (SST), perceived value and satisfaction is developed to augment our understanding on the continuance participation from the intention and behavioral perspectives. The study therefore introduces a continuance participation model that integrates the emotional and informational constructs from the SST, TPB, perceived value and satisfaction in SNSs to establish a theoretical foundation for the study of continuance participation in online communities. A survey conducted on users of SNSs with a total of 285 final respondents empirically tests the continuance model constructs with ten hypotheses using Structural Equation Modelling (SEM) approach and Partial Least Square (PLS) methods to which all nine theorized hypotheses are achieved. The results indicate that social interaction through social support has an intense influence on perceived value and satisfaction resulting in an increased continuance participation intention and behavior in online communities. Additionally, the model reveals that the constructs perceived behavioural control, subjective norms, and attitude from the Theory of Planned Behaviour alongside with Social Support constructs, satisfaction and a perceived value construct significantly influence online communities’ continuance participation intention and behaviour. This paper also seeks to enlighten our knowledge on online communities and tap into the social commerce capabilities particularly looking into continuance participation from the intention and behavioral perspectives. The findings of this study contributes to the social commerce school of thought by theoretically developing research in online communities by proposing social constructs from a social psychology theory in increasing our understanding on continuance model. The theoretical base of this study is the primary contribution of this research. In addition, it complements the minority theoretical background that surfaces in the area of social commerce distinctly looking at online communities

    Knowledge management system (KMS) has become an important asset to the organisation. KMS acting as a tool in supporting organisation knowledge management (KM) practices. The advancement of internet technology makes it easier for organisation KMS working in a collaborative manner. With the rapid development of KMS in organisation, collaboration among these KMS would make a smooth sharing of information. This research aims to scrutinize the governance mechanism of KMS used in managing and controlling the agency KMS. From the previous study, the governance mechanism had been identified based on the development of the conceptual framework. This study investigates the relationships of governance mechanism that consist of two main sub-systems: (1) KMS governance; and (2) collaborative KMS. A survey was conducted by distributing a questionnaire to 25 respondents from eight (8) Malaysian government agencies. The respondent comprises of Community of Practice (CoP), Subject Matter Expert, ICT experts and KM User. The aim of this paper is to determine the validity and reliability of each dimension in the questionnaire using the Rasch Measurement Model (RMM) analysis. The survey was developed comprises 2 sections consisting of 40 items. A total of 21 responses were received. The RMM is used to measure the quality control of item dimensions in the instrument. As a result, almost all the items in the questionnaire constructs were statistically reliable and valid for further analysis, and a few items need to be revised and changed. This specifies that the respondents are reliable and the items are reasonable for this study

    Social commerce is an emerging digital trend that involves participation from online communities. Members of online communities have become influential in ensuring the prolonged usage of social commerce sites. Drawing on the theories of planned behavior and social support as well as satisfaction and perceived value constructs, the purpose of this manuscript is to propose a continuance participation measurement framework. The framework integrates pertinent constructs that drive continuance participation measurement process, which applies the weighted checklist method. A simulation is performed to measure the significance level of online community sites. Additionally, data gathered from four experts confirm the efficacy of the proposed framework. The simulation discussed serves as a guideline and can be useful for developers and managers of social commerce sites for measuring the performance of their online community sites
