Science and technology have become essential components of healthcare. The emergence of Artificial intelligence (AI), Blockhain, mobile techs, Internet of Things (IoT) and Semantic Web Technologies (SWTs) etcetera have amplified the growing influence of technology in global health systems. IoT and SWTs in particular are seen as the next-generation technologies that can revolutionize global health systems. Thus, this paper examines the various potentials of IoT and SWTs in the health sector, with a view to creating more awareness regarding its prospects and associated risks, and also to assist stakeholders to maximize its possibilities to enrich healthcare delivery. We deduced that both IoT and SWTs harbour promising features that are now being deployed in the health sector to enhance quality service delivery, medical research and innovations, smart health, telemedicine, communications, patient care and effective health outcomes just to mention but a few. We conclude that the adoption and implementation of IoT-based devices and SWTs will be significant in sustainability and improvement of healthcare systems in the future. However, privacy and medical data security remains a major source of concern to many stakeholders.

Studies have documented that poor WaSH is accountable for several cases of diarrhea globally, resulting in millions of unnecessary deaths each year, particularly among children, and most notably in underdeveloped countries where poor knowledge and practice of WaSH have been well documented. Therefore, the work prioritizes evaluation of WaSH practice among students in secondary school in Ijebu Ode, in light of the emergence of COVID-19, which has further highlighted the essence of WaSH practice, especially in our schools. A descriptive cross-sectional approach was adopted in the conduct of the investigation, wherein data was sourced from 60 students selected through random numbers from six randomly selected secondary schools (three public and three private), representing a total student population of 360. The data collected through structured questionnaire and personal interview were computed and analyzed descriptively using Microsoft Excel and Statistical Software for Social Scientist (version 20). Findings indicated that majority of the students in Ijebu Ode have adequate knowledge (78.9%) and inadequate practice (45.6%) on WaSH, and thus, concluded that whereas the participants have adequate knowledge on WaSH, it however did not translate into an actual practice. Hence, a need for an intensive effort that will facilitate adequate WaSH practices among the school students through the availability and accessibility of appropriate WaSH resources, with school and home schedules for WaSH practice.

Despite the mounting compendium of scientific evidence that has clearly documented the link between poor housing quality and health both locally and globally, poor housing quality has continued to be a significant concern in public health, especially in rural and sub-rural areas of emerging nations like Nigeria, where there is slight or no knowledge about the public health consequences of poor housing quality. As a result, the object of this work is to observe the housing quality and the perceived health impacts in Ijebu Ode, Nigeria. The work adopted a descriptive but cross-sectional approach, and data was obtained from four hundred (400) systemically sampled households through structured questionnaires, and analysed descriptively using a statistical tool for social scientists. According to the findings, a significant number of the residents 51.5% had no water in their houses, 44% had two windows in the room; out of which only 32% had windows on the two walls of the room, and 33% of the homes were overcrowded with over two people in a room. The findings further revealed that the vast majority of residents reported having cases of malaria with 67.5%, and cases of typhoid and cough with 15.5% and 4.5%, respectively. Consequently, the study has hitherto concluded that housing quality in Ijebu Ode is poor, which is a major predictor of the perceived health effects experienced by the residents.

If used properly, abattoirs can help with disease management, ante- or postmortem investigation of animals and the meat, and can protect the population from most zoonotic illnesses that can develop after eating unsanitary, unsafe, or unwholesome meat or meat products. This underscores the need to examine and explore present abattoir practises in order to better understand the current situation of meat production in Ijebu Ode, Nigeria. Data was retrieved from three (3) government-approved abattoirs using self-administered structured questionnaires, personal interviews, and observations, and the data were computed descriptively using a statistical software for social scientists. Findings from the empirical observation and evidence indicated significant deficiencies in the essential hygiene facilities and services, with the lack of a veterinary laboratory for microbiological confirmation of suspected meat, and all the butchers reported no utilisation of protective gear during slaughtering activities. 66.7% of the abattoirs disposed of their solid waste by open dumping in the nearby bushes, while the wastewater was discharged into public drains. The study revealed that the abattoir practises in Ijebu Ode are unsatisfactory, with unsanitary practises and shortfalls in fundamental hygiene facilities and services, which are critical for producing healthy meat for public consumption. As a result, standardisation of facilities, including the closure of substandard ones, and educational training of abattoir workers were proposed as ways to improve hygiene facilities and practises.

The aim of this study was to evaluate the Ecological Footprint of Energy and Waste generation in Ijebu Ode, and the study adopted descriptive cross-sectional design and data were collected from four hundred (400) systemically sampled households through structured questionnaires, and analysed using descriptive statistics, and inferential statistics. The findings revealed that, water has the highest Ecological Footprint of 86.5%, followed by energy with 6.7%, while EF of food and waste had footprint of 4.8% and 1.9%, respectively, and with an average EF of 0.3gha/capita, it will require 0.2 Earths, should everyone in the world were to consume like Ijebu Ode.
