- Description: There is certainly a need to upgrade our educational system and this can be done through technology-enhanced learning. Technology-enhanced learning can be achieved by developing a web-based ontology e-learning platform, which allows learning to take place ubiquitously. In achieving this task, this research is focusing on analyzing the use of web-based ontology to support the design and implementation of a ubiquitous learning system in South Africa. The implemented web-based ontology e-learning system was deployed and tested. The system testing was done on two variables (Information retrieval and Scalability) of localhost and client system, with the following testing metrics: time is taken for information retrieval, request time to process the request, transfer rate, time localhost receives request, time to respond, roundtrip time for request and network usage. The metrics testing was achieved using apache benchmarking console and gnuplot application to generate the data captured and performance graph, while Wireshark was also used to test/analyze round trip time and network usage through the deployed system. The results of the findings in this study show that the relationship between student and learning content becomes explicit when using ontology technology in searching, organizing, gathering and development content. Results obtained from information retrieval show that the transfer rate of information on localhost for 100 request @ current level of 5 is 37169.89kb/s, while on the client’s system, the transfer rate was 48494.36kb/s which was due to multiple request on the client’s side. Results obtained on scalability shows the round trip time which was (time to respond-time to request). The longest roundtrip was 8 seconds as a result of network being congested with multiple packets request from various sources trying to access the localhost at the same time while the fastest was 1 seconds. The implications of this results show that web-based ontology e-learning system has a positive input to teaching and learning processes in schools for content retrieval and network usage. The system furthermore shows the relationship adopted by learners and teachers, and also the match needs that arise in between. The contribution of this study adds to the existing discoveries on the use of web-based and knowledge-based ontology.

- Description: This study focused on perceptions and experiences of Ward-Based Outreach Teams in implementing Primary Health Care Re-engineering at Nyandeni and Mhlontlo Sub-Districts in OR Tambo District. Primary Health Care (PHC) is defined as essential health care, devised to be universally accessible to the community through means acceptable to them, with their full involvement and at costs that the community can afford. The National Department of Health (NDoH) introduced the new strategy of Ward-Based Outreach Teams (WBOTs) that are regarded as the key stakeholders in this effort, as they render health services at households. WBOTs are allocated in different municipal wards and are supposed to visit the population, irrespective of race, socio-economic status and geographical setting. The aim of the study was to explore and describe the perceptions and experiences of Ward-Based Outreach Teams in implementing the RPHC at Mhlontlo and Nyandeni sub-districts. The qualitative research design was employed to reach the objectives of the study. The sample used was all WBOTs who had been working for more than one year and had undergone WBOTs training for ten days. Self- structured questionnaires, one-on-one interviews and a focus group were used to collect data from different categories of WBOTs. The researcher adhered to the ethical standards of nursing research as explained by the Democratic Nursing Organization of South Africa, such as anonymity, confidentiality, privacy and quality research. Participant’s names were not written on the questionnaires. The data was analyzed using themes, categories and sub categories, the statistical package for social sciences. Bar graphs and tables were used to communicate data. The results of the study showed that WBOTs are essential to needy households and individuals. The study revealed that the job of Community Health Workers (CHWs) involved community mapping, giving health education talks, household registration, tracing of defaulters, referring needy clients to health facilities depending on severity of illnesses and building relations with other government organizations, namely the Department of Home Affairs, to help clients obtain birth certificates and identity documents, the Department of Social Development, for social problems within households, and the Department of Education, acting as partner for the overall welfare of students. The results of the study revealed that shortage of outreach teams, limited resources, inconsistence in recruitment of Health Promoters and Community Health Workers causes psychological distress, frustration, absenteeism, less concentration when serving communities and impacts on the service delivery system. Therefore,it is recommended that the Department of health should provide outreach teams with medical equipment, dedicated transport, trainings and improve recruitment and retention strategy. In conclusion, the findings of this study indicated that the department of Health has taken the right direction with this programme and that some cooperation does exist between health and other departments.
