This led so many institutions in Nigeria and abroad to adopt video conference systems (such as zoom, even though it is used by an insignificant number of academicians) to facilitate academic activities through virtual teaching and learning. More than 80% of young students have negatively been affected by their educational activities due to the closure of all schools globally because of the COVID-19 pandemic. The teaching and learning in most Nigerian institutions are based on face-face contact which was paralyzed due to the COVID-19 lockdown. Institutions are called on to adjust their pedagogical practices and adapt to the learning needs of the students beyond the classroom walls as online learning is perceived to be the best method in order to minimize direct contact. The purpose of this meta-analysis was to examine the effect of perceived usefulness and perceived ease of use on zoom classrooms towards learning motivation. A literature search was performed using prominent internet databases between 2018 to 2023. Sixteen published articles fulfilled the review requirements set for incorporation. The small amount of articles resulting from this search indicates that in recent years the use of video conferencing systems has been investigated to some higher extent in using zoom classroom. Results from the sixteen articles disclosed that zoom classroom remains a promising instructional instrument that awaits further exploration in Nigeria. To enhance the knowledge of learners in Nigerian institutions, the research proposes among other things that, adoption was limited in developing countries like Nigeria due to the factors such as limited power supply, internet subscription costs, and limited internet service.","PeriodicalId":472973,"journal":{"name":"Journal of mathematical sciences & computational mathematics","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135901753","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}

It was introduced as a way to approximate classical sets using lower and upper bounds. Rough set theory has been applied to various domains such as data mining, knowledge discovery, machine learning, soft computing, medical analysis, synthesis of switching circuits, and civil engineering. Rough set theory can handle imprecise and noisy data by finding structural relationships and dependencies among attributes. It can also reduce redundant and irrelevant attributes and generate decision rules from data. Rough set theory is closely related to fuzzy set theory, but differs in that it uses multiple memberships instead of partial memberships to model uncertainty. Lot of research works have taken place in this domain with many fruitful outcomes that helped lot in expanding this field to much wider reach of knowledge irrespective of the domain concerned to mathematical and technological application development. In lieu of such research-oriented progress in different versatile domain, many areas of research has remained untouched as many a problem remained unsolved being shrouded under the mystery. This paper deals mainly with some of the still unsolved questions on Rough Set that are under study for new discovery and a way to overcome such limitations citing proper techniques, examples, working models, and graphs.","PeriodicalId":472973,"journal":{"name":"Journal of mathematical sciences & computational mathematics","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135901750","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 improve the quality of life of citizens and lead to sustainable economic and social development; the party and the government has highlighted as crucial to the development of the water sector. the Some projects have been completed implement, but some of them were not matched to technical standard. Concessionaire seeks to cancel or sell the concession contract to others because they had invested, and the return is less than ought.

This assessment aims to study and evaluate the financial performance of MuangKhay Water Supply System, Luang Prabang City, Luang Prabang Province that invest and operate by the private sector, and Build-operate-transfer for 30 years. To do this we collect data with the private operator which cost of investment, personnel, an average of chemicals, operation fees, electricity, etc., to calculate the Payback Period, Net Present Value, Internal rate of Return, and Cost Benefit Ratio.

This study aims to contribute to this issue, in the competitive context of the tuberculosis diagnosis and treatment centres (DTC), and to describe the spatial distribution of the residence of TB patients and DTC, to understand the DTC attendance' rate in the city of Douala, Cameroon. The Spatial analysis was performed to access the spatial-economic model hiding behind the distribution of the \"observed\" number of patients attending the DTCs compared to the \"expected\" number. Multivariate analysis using logistic regression and the analysis of variance were used to identify the factors associated to the demand and supply of DTCs respectively. The decentralization policy advocated by the national program against tuberculosis (NTP) is not always followed by the patients: The \"expected\" and the \"observed\" number of patients in DTCs are not correlated. The attendance of DTCs in Douala is in accordance with the spatialeconomic theory models of Salop and Hotelling, which is an artefact. Patients seeking treatment in DTCs closer to their residence are mainly women and patients from relative poor households, while attendance of DTC was associated with the quality of service and the level of the HF. Attendance HF is dictated by the spatial-economic theory models. The policy of creating HF for TB is not followed by patients in competitive context. Attendance of HF by TB patients is associated with socioeconomic factors;","PeriodicalId":472973,"journal":{"name":"Journal of mathematical sciences & computational mathematics","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135704516","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}
