Problems of Electronic Commerce Applications in a Developing Country: A Descriptive Case Study of the Banking Industry of Oman

ABSTRACT Internet banking is a relatively new area and there are several issues, which have been generally untouched and are therefore open to further investigation, especially in the developing countries. Hence, this study is a step in this direction. This research has been focused on investigating to identify and highlight the main potential factors or impediments that are currently inhibiting the incorporation or adoption of Electronic Commerce (EC) applications expansion in the Omani banking sector. Data, obtained for the first time, were collected using semi-structured interviews and a survey questionnaire as well as by reviewing some bank documents. The study explores the slow uptake of EC application in the banking industry. The objectives of the research, therefore, were to identify factors enabling or inhibiting the successful adoption and use of ecommerce applications within the banking industry of Oman. The results provide a pragmatic picture of the adoption of EC applications in the country's core financial sector domain. One of its main findings is that security and privacy issues were found to be a serious inhibiting factor. Other factors such as power relationships (as conflict between managers can often emerge during the process of IS/IT adoption). Banks adopting and implementing Internet banking services and applications face several management and social problems and challenges. Although the research context is quite specific, it is believed that the findings are of relevance to other industries and other developing countries

Postirradiation Osteosarcoma of the Maxilla: A Case Report and Current Review of Literature

Background. Radiation-induced sarcomas are well-known potential late sequelae of radiation therapy. They are of rare occurrence in jaw bones and are even rarer in the maxilla. Case report. We report a case of radiation-induced osteosarcoma involving the maxilla in a patient treated with radiotherapy for nasopharyngeal carcinoma 14 years ago. Despite neoadjuvant chemotherapy, surgical treatment could not be performed, and the patient received palliative chemotherapy. Conclusions. Radiation-induced osteosarcomas are aggressive and often elude early detection and timely intervention, rapidly leading to early demise of afflicted patients. Long-term patient follow-up and a high index of suspicion are crucial for timely intervention

BREASTFEEDING PRACTICE AND MOTHERS AWARENESS AND PRACTICE OF ABSOLUTE BREASTFEEDING IN ARAR, SAUDI ARABIA

Background: Human milk meets all the nutritional requirements of infants for the first 6 months of life, and it is associated with a lower incidence of diarrhea than partial or artificial feeding. The infant should be exclusively breastfed for at least 4 months of life and if possible for 6 months, as recommended by WHO and UNICEF. Objectives: The main objective of this study was to determine the breastfeeding status for children under 24 months in Arar city, and to determine breastfeeding practice in relation to some socidemographic and nutrition related variables. Participants and methods: A cross-sectional study was carried out in Arar city, mothers were selected from the attendees of the female side of 6 randomly selected primary health care centers in the city. They interviewed and filled a questionnaire which included the needed questions. Results: Among the 400 studied children,17.2% got breastfeeding, 41.0% had both breast and artificial feeding while 41.8% depended on artificial feeding only. Absolute breastfeeding in the first 6 months of life was found in 34.7% of infants and in the first 4 months of life was found in 13.8%. Sources of health education of the mothers about absolute breastfeeding period were doctors in 12.1%, health education team of the hospitals in 24.1%, relatives and friends in 11.8%, the media in 3.8% while no health education about absolute breastfeeding period was reported by 48.2% of the studied mothers. The reported causes of artificial feeding was difficulty of breastfeeding during working hours in 41.8%, missing of support in 25.7%, preference of formula milk in 11%, thinking that breastfeeding leads to breast enlargement and redundancy in 8.6% and thinking that breastfeeding leads to obesity of the mothers in 4.5%. No significant relationship between type of child feeding and child age, sex, mother education, mother's working status, father's work or mother age group [P >0.05]. Conclusion: 17.2% got breastfeeding, 41.0% had both breast and artificial feeding while 41.8% depended on artificial feeding only. Absolute breastfeeding in the first 6 months of life was found in 34.7% of infants and in the first 4 months of life was found in 13.8%. With deficiency of exclusive breastfeeding among infants of Arar, Saudi Arabia. Programs promoting exclusive breastfeeding in the first 6 months of age must be conducted to increase mothers’ awareness of the exclusive breastfeeding duration is recommended.

Involvement of Different CD4 + T Cell Subsets Producing Granzyme B in the Immune Response to Leishmania major Antigens

The nature of effector cells and the potential immunogenicity of Leishmania major excreted/secreted proteins (LmES) were evaluated using peripheral blood mononuclear cells (PBMCs) from healed zoonotic cutaneous leishmaniasis individuals (HZCL) and healthy controls (HC). First, we found that PBMCs from HZCL individuals proliferate and produce high levels of IFN-and granzyme B (GrB), used as a marker of activated cytotoxic T cells, in response to the parasite antigens. IFN-is produced by CD4 + T cells, but unexpectedly GrB is also produced by CD4 + T cells in response to stimulation with LmES, which were found to be as effective as soluble Leishmania antigens to induce proliferation and cytokine production by PBMCs from immune individuals. To address the question of regulatory T cell (Tregs) involvement, the frequency of circulating Tregs was assessed and found to be higher in HZCL individuals compared to that of HC. Furthermore, both CD4 + CD25 + and CD4 + CD25 − T cells, purified from HZCL individuals, produced IFN-and GrB when stimulated with LmES. Additional experiments showed that CD4 + CD25 + CD127 dim/− Tregs were involved in GrB production. Collectively, our data indicate that LmES are immunogenic in humans and emphasize the involvement of CD4 + T cells including activated and regulatory T cells in the immune response against parasite antigens

Design and implementation of the European-Mediterranean Postgraduate Programme on Organ Donation and Transplantation (EMPODaT) for Middle East/North Africa countries

This prospective study reports the design and results obtained after the EMPODaT project implementation. This project was funded by the Tempus programme of the European Commission with the objective to implement a common postgraduate programme on organ donation and transplantation (ODT) in six selected universities from Middle East/North Africa (MENA) countries (Egypt, Lebanon and Morocco). The consortium, coordinated by the University of Barcelona, included universities from Spain, Germany, Sweden and France. The first phase of the project was to perform an analysis of the current situation in the beneficiary countries, including existing training programmes on ODT, Internet connection, digital facilities and competences, training needs, and ODT activity and accreditation requirements. A total of 90 healthcare postgraduate students participated in the 1-year training programme (30 ECTS academic credits). The methodology was based on e-learning modules and face-to-face courses in English and French. Training activities were evaluated through pre- and post-tests, self-assessment activities and evaluation charts. Quality was assessed through questionnaires and semi-structured interviews. The project results on a reproducible and innovative international postgraduate programme, improvement of knowledge, satisfaction of the participants and confirms the need on professionalizing the activity as the cornerstone to ensure organ transplantation self-sufficiency in MENA countries
