Cocoa pod breaking is a key step in the process and reliance on manual methods has largely remained unaddressed. One adverse effect of reliance on manual labour is the level of child labour in cocoa production increases. Aside from the manual process being ineffective, another implication is the risk the manual process exposes farmers to. This paper documents the design and local fabrication of a mobile cocoa pod-breaking machine that automatically separates the beans from the husk and placenta, using mechanized blades and a sieve system, thereby improving productivity, reducing labour cost, and on-farm hazards. Preliminary testing of the machine’s performance indicates efficiencies of 90-98% and bean damage of less than 2%. The business potential of this machine is also described.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132742280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Communication with the Deaf is usually done through sign languages, which relies heavily on vision. This is a major challenge during emergency situations involving the Deaf, when there is a need to contact emergency services; because most emergency service contact numbers are voice-based thereby making it difficult for a Deaf victim to describe the nature of aid required. The aim of this research effort is to design a sign support emergency mobile application for Deaf people, to avail them the same level of access to emergency services as hearing people. This is done by using a cross-platform mobile application, called SignSupport, which was developed by following an iterative co-design methodology, with the local Deaf communities, emergency service providers and domain experts as collaborators. The developed app was rigorously tested and deemed usable and effective by the stakeholders.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115569834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To make available simpler FMIS and also aid farmers effectively and efficiently manage their farm activities, this project designed and developed a Livestock Farm Management Information System (LFMIS). Towards the development of the system, participants were chosen from the Khomas region of Namibia. The developed system is able to allow farmers to record livestock information and track their progress, manage farm resources with accounting capabilities, manage calendar events, and reminders of important farm events, such as treatment, connect with buyers, connect with relevant farm, stakeholders, and access seasonal progress, pest and production information. The developers are optimistic that the system would benefit farms and farmers by making them more efficient and effective. Considering that the system currently does not manage calendar events, and reminders of important farm events, such as treatment and does not also automatically alert famer of animal diseases, it is recommended that similar future systems or higher versions of this system incorporate the said features.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"427 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114952073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic abnormality in all patients with COPD is airflow limitation. The main method for diagnosis of COPD is using spirometer and imaging equipment, which are expensive and not suitable for use. This study aims at developing algorithms for analysing cough sounds for detecting COPD. CNN and CRNN based deep learning techniques are used for developing the algorithm. We have used both augmented and non-augmented datasets with three different feature extraction methods: Mel-frequency cepstral coefficient, zero crossing rate, and harmonic change detection function. The developed CNN and CRNN scored an accuracy of 96.6% and 96.73% respectively. Conclusion: The proposed algorithms have improved classification performance that had been reported in the literature. Significance: The results of this study suggest that automatic diagnostic tools can be developed with less intervention from healthcare professionals.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"324 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121839215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the huge impact of the data generated at the lowest level of the health sector in performance monitoring, decision making, planning and measuring progress prompted the need to have digital solutions. When digital tools were introduced; most of them were only addressing a single functionality or programme, resulting with a lot of fragmentation and siloed systems. Therefore, most of the information systems in place are not holistic, what is missing is information systems that are integrated in nature, encompassing all the patient and programmes data. The Malawi MoH through the Community Health Services Section (CHSS) in collaboration with other departments is implementing an integrated community health information system (iCHIS), resting upon an open-source, web-based platform – DHIS2. The goal of this paper is to discuss the role that different communities of practice (CoP) played in the different phases of iCHIS development and implementation. Drawing on case material from several CoPs in the Malawi health sector community level, a case is built around the use of CoPs, arguing that if the different communities are well coordinated and collaborated, they will be able to enhance the integration of the community health information system. In this paper, we analyzed how the interaction of different CoPs have led to the successful implementation of the integrated community health information system (iCHIS) in the Malawi health sector. Five CoPs were identified namely: policy makers, developers, users, facilitators and supervisors CoPs.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120848162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, more research is required to explain the factors that could potentially influence voters, particularly the youth demographic (18-35 years), to adopt e-voting technology. This research investigated the factors that influence the intention of young South Africans to adopt electronic voting in South Africa by combining constructs from three theories: theory of planned behaviour (TPB), technology acceptance model (TAM) and the diffusion of innovation theory (DOI). An online survey was used to collect data (n=412). Confirmatory factor analysis applied on a pre-tested and pre-validated quantitative survey reveal that technology stickiness, access to ICT, ICT skills, attitude towards ICT, relative advantage and political affiliation influence the intention to use e-voting. This research provides actionable insights for stakeholders in the electoral process management regarding e-voting adoption in the global South.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132758791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An interactive remote wind energy laboratory (lab) was developed in this study. The lab enables remote experimentation via the internet about the variables on which wind power output depends, including; wind speed, temperature, humidity, number of turbine blades, and pitch angle. The lab setup consisted of; wind fan, wind speed sensor, miniature wind turbine, NI ELVIS II prototyping board, and Arduino microcontroller. The sample results and wind power curve generated were found to be similar to those from hands-on experiments. The lab can be used for demonstrations, in circumstances of inadequate wind power hands-on experiments, and where there are many students.","PeriodicalId":142887,"journal":{"name":"2022 IST-Africa Conference (IST-Africa)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126599054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
