Communicable diseases are a long-standing global concern. This research was driven by the need for Environmental Health Practitioners (EHPs) to comply with the regulations defining the scope of practice for Environmental Health. Section 5 outlines the role of EHPs in communicable disease surveillance (CDS). Therefore, the EHPs’ perception of this function could influence the quality of service in the City of Ekurhuleni Municipality (CoE). The objective of this study was to determine the EHPs’ perceptions with regards to communicable disease surveillance (CDS). A descriptive study that encompassed qualitative methods with a total population of 95 EHPs, consisting of senior EHPs and Environmental Health Managers respectively was employed. The study participants reported a wide range of opinions regarding the improvement of CDS, including training, reporting systems, specialization and development of standard operating procedures. A significant number reported dissatisfaction with the way CDS is performed in the CoE. This study has demonstrated that provisions of the regulations are not optimally adhered to. Therefore, these results may facilitate the creation of a comprehensive approach in addressing CDS by EHPs. This approach should guide policy formulation by the national government and aid in CDS.

The number of the Internet of Things (IoT) patterns in the literature is growing rapidly. As a result, this makes it difficult to identify and differentiate a pattern from a large number of related patterns. Thus, there is a need for organizing these patterns in a meaningful way to facilitate speedy retrieval and guide the IoT architects in building a classification scheme that groups a family o f r elated patterns together. The classification of these patterns is often made difficult by the fact that the names of these patterns generally do not reveal the core essence of the pattern. In order to understand the essence of a pattern, users are generally expected to go through several pages which may still be obscure and difficult to understand due to semantic barriers and richness of language. Intuitively, this problem can be addressed by assigning a few verbal predicates that best describe the core essence of each pattern. In this paper, we show that Formal Concept Analysis (FCA) and Concept Lattices are suitable tools to support this task. Accordingly, we make use of FCA to build a concept lattice, which serves as a semantic index to model terms that define the core attributes of each pattern. We introduce the notion of attributes hierarchies to scientifically identify the one main concept that seems to underlie the meaning of each IoT pattern. The more significant attributes for the pattern are represented by concepts that branch out of the root node concept, forming leaf nodes down the hierarchy. This concept lattice feeds from information taken from a few pre-identified sentences taken from a document. These are sentences that describe the core attributes of the pattern. By quantifying sentence similarity between these preidentified sentences and other sentences in the document, we can identify sentences from which we can extract concepts for building the concept lattice. Experimental results show a promising performance in using this approach for organizing the IoT patterns.

Health is the biggest challenge to a majority of citizens regardless of age group and with the shortage of major components in the healthcare sector, life expectancy tends to reduce due to a lack of facilities. Technology on the other hand is reaching out to meet some of the demands that the healthcare will continuously require in order to deliver their services on time. One such technology is known as the internet of things (IoT). IoT has already proven its great potential towards the healthcare domain. IoT has the ability to allow patients to be monitored from the comfort of their homes through sensors equipped within devices deployed to perform specific tasks. The other technology is none other than the Blockchain which was introduced to deliver its capabilities in the financial ledger. The Blockchain helps to keep track of all the transactions being recorded, which in healthcare sector the need for Blockchain can be transformed to keep a trace of patient records. Since the IoT devices have the capability to monitor vital signs in the human body, it will be of a great achievement to integrate it with the Blockchain to keep an efficient system of healthcare records. The approach of this work is presented based on an Blockchained-IoT system to improve challenges of storing patients’ data captured by wearable IoT devices to help medical caregivers to make more informed decisions based on the efficient healthcare record-keeping. The design science approach will be proposed in our research to run the full experiment of our work.

The need for Knowledge Management Systems (KMS) in South African Metropolitan Municipalities has certainly become heightened in recent years. In the case of this study, City of Johannesburg Metropolitan Municipality (CoJ) is used as a case study. The main aim of the KMS is to ensure that relevant organisational experiences and knowledge generated both internally and externally are captured and shared to achieve strategic objectives of the organisation. The Organizational Culture Theory (OCT) has not been used much in South Africa, particularly with knowledge management systems. This paper intends to contribute to the South African literature through this study by using OCT to develop the KMS Adoption and Use (KMSAU) Framework.
