    Get PDF
    Organizational change is vital for an organization to survive and stay competitive. A collective organizational member’s cooperation and commitment are needed in the successful implementation to provide a better service delivery to customers. Measuring organizational readiness for change at an organizational-level is more advantageous because the collective organizational members will more capable of learning new methods and tools and confident the change will success. There are five classes of antecedents that have direct effects on organizational readiness in IS adoption: attributes of change, leadership support, internal context, attributes of change target and IT support. By understanding readiness, organizational leaders may improve their ability to implement planned changes and with that the proximal outcome of organizational readiness will improve efficiencies and productivities

    Most ICT projects failed due to various factors including organizational issues and leaders who did not sufficiently assess organizational readiness for change. Although various perspectives and criteria have been used by researchers to measure organizational readiness, reported evidence on its measurement in information systems (IS) adoption is still limited and unclear, which calls for clarification and further studies. The purpose of the paper is to discuss the evaluation of IS adoption in organizational readiness using an extended organizational readiness framework and to identify the factors that influence organizational readiness in IS adoption. A case study was conducted on the Human Resource Management Information System (HRMIS) based on the Framework of Organizational Readiness at the Public Service Department (PSD) of Malaysia. This qualitative study involved interviews, observations and document analysis. The study found that the PSD is set to implement the HRMIS but the issues and problems identified as pertaining to the HRMIS must be addressed and dealt with immediately in order to achieve the system objectives. A number of factors influencing organizational readiness were identified in the adoption of the HRMIS: Attributes of the Change (vision clarity, change appropriateness and change efficacy), Leadership Support (top management support, presence of an effective champion, and IT support), Internal Context (organizational history of change, organizational conflicts and policies, and organizational flexibility) and Attributes of the Change Targets (collective self-efficacy and user training). Although our case study focused on a specific setting, the identified factors and proposed framework extension is potentially useful for assessing other information systems in different settings; the findings could act as a guide for assessing organizational readiness prior to the adoption of information systems

    Treatment using plant materials has been widely researched and observed to assist in curing a disease. Medicinal products derived from herbal plants are proven useful as drugs must follow guidelines not to cause acute or chronic toxicity. The purpose of this study was to investigate the teratogenic potential of an ethanolic sappan wood extract on the growth of unborn rats. Six groups of pregnant rats are created: Aquadest was administered to the Control group, whereas the Treatment groups received 100, 200, 300, 400, or 500 mg.kg-1 BW of an ethanolic extract of Sappan wood. On the twenty-first day of gestation, pregnant rats were CO2-euthanized and delivered vaginally. Rats' body weight during pregnancy was observed, along with fetal growth measurements, viscoelastic examination, and skeletal development. Wistar rats' reproductive systems, fetal body weight, body length, and tail length were all unaffected by ethanol extract of Sappan wood at doses from 100 mg/kg to 500 mg/kg. In fetuse rat from the control group and the five dosage groups, no skeletal development had taken place and there were no obvious external abnormalities. Even at the maximum dose of 500 mg, sappan wood extract demonstrated no teratogenic effects on the development of fetal rats.kg-1 BW

    Heated vegetable oils and cardiovascular disease risk factors

    Get PDF
    Cardiovascular disease (CVD) is one of the leading major causes of morbidity and mortality worldwide. It may result from the interactions between multiple genetic and environmental factors including sedentary lifestyle and dietary habits. The quality of dietary oils and fats has been widely recognised to be inextricably linked to the pathogenesis of CVD. Vegetable oil is one of the essential dietary components in daily food consumption. However, the benefits of vegetable oil can be deteriorated by repeated heating that leads to lipid oxidation. The practice of using repeatedly heated cooking oil is not uncommon as it will reduce the cost of food preparation. Thermal oxidation yields new functional groups which may be potentially hazardous to cardiovascular health. Prolonged consumption of the repeatedly heated oil has been shown to increase blood pressure and total cholesterol, cause vascular inflammation as well as vascular changes which predispose to atherosclerosis. The harmful effect of heated oils is attributed to products generated from lipid oxidation during heating process. In view of the potential hazard of oxidation products, therefore this review article will provide an insight and awareness to the general public on the consumption of repeatedly heated oils which is detrimental to health

    Tocotrienol Attenuates Stress-Induced Gastric Lesions via Activation of Prostaglandin and Upregulation of COX-1 mRNA

    The present study aims to distinguish the effect of tocotrienol on an important gastric protective factor, prostaglandin E2 (PGE2), in stress-induced gastric injury. Twenty-eight Wistar rats were divided into four groups of seven rats each. Two control groups were fed commercial rat diet, and two treatment groups were fed the same diet but with additional dose of omeprazole (20 mg/kg) or tocotrienol (60 mg/kg). After 28 days, rats from one control group and both treated groups were subjected to water-immersion restraint stress for 3.5 hours once. The rats were then sacrificed, their stomach isolated and gastric juice collected, lesions examined, and gastric PGE2 content and cyclooxygenase (COX) mRNA expression were determined. Both the regimes significantly attenuated the total lesion area in the stomach compared to the control. Gastric acidity, which was increased in stress, was significantly reduced in rats supplemented with omeprazole and tocotrienol. The PGE2 content was also significantly higher in the rats given tocotrienol supplementation compared to the control followed by an increase in COX-1 mRNA expression. We conclude that tocotrienol supplementation protected rat gastric mucosa against stress-induced lesions possibly by reducing gastric acidity and preserving gastric PGE2 by increasing COX-1 mRNA
