Abstract: Background CA-125 is used as a marker in the diagnosis, treatment, and follow-up of ovarian cancers. High CA-125 levels indicate a high tumor burden, large ascites volume, and advanced stage. In the present study, the predictive value of CA-125 for the prognosis of ovarian cancer patients was determined. Materials-Methods The data of 173 patients diagnosed with ovarian cancer between 2009 and 2021 were analyzed retrospectively. CA-125 values before primary treatment were recorded. All patients underwent neoadjuvant chemotherapy or primary tumor surgery. Patients with normal CA-125 values at the end of treatment, and those with residual tumor, were followed up until the first recurrence. Disease-free and overall survival were analyzed. Results According to the preoperative CA-125 values, the disease-free survival time before treatment in patients with CA-125 levels of 0–40, 41–120, and > 121 U/ml was 73, 59.8, and 54 months, respectively; the differences were not statistically significant (p = 0.174). Patients with a ≥ 3-fold increase in their CA-125 value at recurrence had shorter overall survival (0–40 U/ml: 86 months; 41–120 U/ml: 60 months; > 121 U/ml: 54 months; p = 0.025). For patients without residual tumor after surgery, overall survival was 61 months, but it was significantly shorter (38 months) in those with residual tumor > 1 cm (p=0.001). Conclusion Levels of the tumor marker CA-125 are used to determine the response to treatment, residual tumor, and disease recurrence in ovarian cancer patients. Although elevated CA-125 levels alone do not contribute to the prognosis, patients with values 3-fold higher than before treatment had shorter overall survival.

Abstract: The Covid-19 Pandemic affected world economies unimaginably, not leaving out the educational sector. Standardised educational assessments commonly deployed as paper-pencil in less developed countries faced challenges that call for technological adoption. The study was qualitative research of case study type. The study population was top-level officials in national examination bodies in Nigeria who served as key informants sampled using purposive and snowball techniques. In-depth interviews were conducted for data collection supported by documentary analysis to examine the perception and prospects of adopting Computer Adaptive Testing for Standardized Educational Assessment with case Studies from West and South Africa. Findings revealed that key informants positively perceived computer adaptive testing and were seen as consistent with current practices, experiences, and needs. The prospect of adopting the technology by examination bodies in West Africa was relatively high. However, there are myriad challenges to overcome to bring this to reality. Considering these findings, some recommendations were given. Keywords: Perception, Prospects, CAT, Standardised testing, Educational assessment, Covid-19, Less developed countries.

Abstract: Meaning and identity construction is important not only when libraries are used as spaces for managing Indigenous Knowledge (IK) but also in situations involving social interaction. The implication is that IK tends to attract different meanings and identities depending on persons in various contexts where it is managed. The research sought to establish the meanings and identities constructed when indigenous knowledge is managed by academic libraries. A qualitative approach which utilised a phenomenology research design was adopted. Open-ended questionnaires, unstructured interviews, observation and photo documentation were utilised to gather data from 60 participants sampled from three universities in the Eastern Cape Province of South Africa. The findings revealed that there are commendable efforts to create space for IK within libraries, but that their collection needs to be transformed and decolonised by collecting, documenting, organising, storing, and disseminating more indigenous knowledge, as well as promoting it for sustainable development. The study concluded that academic libraries were not doing enough and suggests that they be viewed as information and educational resources for the community outside the institution. They also need to open their doors to the youth for them to learn about their IK and develop pride in their heritage.

Abstract: The collection of the Fees Must Fall Movements (FMFM) records are new to most\narchivists and records managers in South African universities. This paper aims to\nassess the collection of records during the Fees Must Fall Campaign using a Multiple\ncase study design. Qualitative data were collected through interviews with selected\narchivists and records managers from the University of Johannesburg, the University\nof Witwatersrand, and the University of Cape Town, and subjected to document\nanalysis. The study established that most of the FMFM campaigns were not\ncollected/documented by the university archive repositories. It emerged that there\nwere no clearly developed strategies to collect FMFM. Therefore, the study\nrecommended that universities develop clear strategies for data collection and\nencouraged collaboration and partnership in the collection FMFM.

Abstract: Good teaching in higher education is largely believed to be an important variable in the student success matrix. Universities therefore invest a significant part of their time in developing their academics through postgraduate teaching qualifications so as to enhance their teaching competence and effectiveness. This research critically examined the experiences of a group of academics at a university in South Africa that had recently graduated with a VTED. The study adopted a qualitative methodology where data were collected by means of an in-depth interview schedule. The study revealed that the VTED was well received by the participants as it enhanced their conceptualization of teaching and learning matters. The major recommendation was that university appointment boards should consider this qualification as a requirement for appointment as a university teacher and where one is appointed without it then one should be supported to acquire the qualification within five years of appointment

Abstract: This study sought to establish stakeholder perceptions of the state of readiness of the Eastern Cape Department of Education to respond to COVID-19 pandemic. The study adopted a case-study design within a qualitative approach. Data was gathered from two subject specialists, 11 principals and 11 teachers in one district of the Department of Education (DoE) in South Africa through semi-structured telephonic interviews. Data was analysed through a thematic analysis framework after themes were generated during content analytical processing of the data. Permission was sought from and granted by the participants. Findings revealed that the district was plagued by inaccessibility and lack of savviness about information and communication technologies and related resources which manifested through poor ICT infrastructure and lack of blended learning pedagogy and policy. It also emerged that teachers and learners lacked motivation to use ICTs in teaching and learning which was evident through lack of personal drive. Poor visionary leadership and management in schools costed decision making processes, as well as lack of effective ICT teacher training and induction opportunities. The study concluded that while the DoE is desperate to rescue the school calendar, findings indicated strongly that the province was not ready. Recommendations include the need for the DoE to implement ICT for teaching through intense teacher training on the use of these tools and technologies to enable appropriate near future implementation of online learning and e-learning technologies. Internet connectivity should also be prioritised and be made readily available to learners.

Abstract: This study investigated the consequences of equipping 30 students with Tablet Personal Computers (TPCs) on their learning processes in technical-oriented practical programmes at a rural-based Higher Education Institution in South Africa. The study adopted a case study design within a mixed methods approach and used the constructs of the 2nd Generation Activity Theory. Instruments were constructed Google Forms that were validated through peer debriefing. Quantitative data was analysed through descriptive statistics and qualitative data through content analysis. Findings revealed contradictions in the forms of bureaucratic-motive; technology-ineptness and digital-disruption, and tensions in the forms of pedagogical-motive; stakeholder-agency; self-motive and institutional-motive. Conclusions include that though there was some evidence of learning, there was also evidence that behavioural use deviated from behavioural intentions. There were no change agents early in the adoption process and there was the notion that education technologies automatically motivated learning. Recommendations include that the pervasive nature of technology requires astute and comprehensive technology adoption strategies which include stakeholder-empowerment, development of change agents and increased agency footprints. There is also need to prescribe appropriate technology affordances for a given context so that students utilise TPCs as “tools” for learning and not “toys” for entertainment.

Abstract: Fuel plays a pivotal role in the economic development of every developing country, which means many sectors of the economy will be unfavourably affected by increasing the price of fuel. This paper reviews and analyses annual data on fuel prices from 1998 to 2022. Data were analysed using Autoregressive Integrated Moving Average (ARIMA) (1,1,2) to predict the price of fuel from 2022 to 2032. The ARIMA (1,1,2) model was used due to its accuracy, mathematical soundness, and flexibility, thanks to the inclusion of AR and MA terms over a regression analysis. The results showed that ARIMA (1, 1, 2) was the best fit for the price of fuel since its errors are smaller than Simple Exponential Smoothing (SES), Double Exponential Smoothing (DES), and Triple Exponential Smoothing (TES). Results of the study also showed that the fuel price will increase from 2022 to 2032 in Zambia. These results are useful to policy and decision-makers such as Zambia Revenue Authority (ZRA), Energy Regulation Board (ERB), and Ministry of Transport, Works, Supply and Communications (MoTWSC) in a bid to plan and execute their duties effectively.

INVESTIGATING THE ADOPTION OF SMART HEALTHCARE MONITORING SYSTEM IN THE RURAL AREA

Volume 78, Sep 2022
doi: 10.21506/j.ponte.2022.9.3
View Abstract Hide Abstract   |   Download PDF
Abstract: Smart healthcare (SH) uses a new generation of information technology (IT) such as the internet of things (IoT), cloud computing, big data and artificial intelligence (AI), making smart healthcare efficient, convenient and personalized. In the rural areas, patients are not being monitored regularly and properly due to the shortage of doctors, nurses and other healthcare personnel. These among other issues require SH adoption which is a key to enriching the living standard in rural areas. However, why the low level of adoption of this technology in the rural areas of developing nations remains a research challenge. Hence, this study investigates the reason for the low adoption of SH in the rural area, using Libode township as a case study. Data were collected from 50 participants through a structured interview. The data collected was analysed using a statistical package. This research found that despite the fact that the majority of the people in the rural area are not satisfied with the current healthcare service delivery, they are still using it because they are not aware of other options. A low level of awareness and poor connectivity problems are the two major reasons why there is still a low level of adoption of SH in the rural areas, despite this technological advantages. The study recommends among other things that the healthcare departments raise awareness of smart healthcare benefits among rural area people to help sensitize them.
