AFROCENTRIC PEDAGOGY APPROACH IN THE CURRICULUM OF EDUCATIONAL SYSTEM RENEWAL IN AFRICA: A CASE OF SOUTH AFRICA
Get PDFThe purpose of this paper is to conceptualize in greater detail the educational system approach that is being imposed into African countries, South Africa as a case in point. Over the past years, Sub-Saharan countries have and still experience indoctrinated educational system in which the content is mimicked from purported hegemonic states such UK, USA and other western counties inter alia. The problem of education retrogrades from the prior independence of African countries in the early 1960s wherein, the colonial masters organized and silently played a crucial role in shaping the formation of education in Africa; and not much has changed in terms of education since then. A particular concern is that the system of education might have designed to impoverish African people and perpetuate dependency to the western nations. Hence, at the core center of the educational system is the curriculum which seem to be inevitable and requires an alteration, particularly in South Africa. Therefore, the outlook of this paper is to critique and interrogate the system of education in South Africa looking at the socio-economic development and a continuous alteration in respect of the curriculum. The paper shows that for the realization of African renaissance, ideals of Africa Agenda 2063 and accelerated development, the system of education must be transformed and be Africanized to benefit the people of Africa. The paper uses literature-based approach as a methodological framework in order to analyze the status quo of education in South Africa. The paper concludes and recommends that the transformation of current educational system requires an alteration to the inclusive of indigenous knowledge to vigorously respond to socio-economic woes in Africa. Furthermore, the paper advocates for indigenous knowledge consideration in the incessant curriculum renewal
GOVERNMENT OF THE PEOPLE, BY THE PEOPLE, AND FOR THE PEOPLE: STAKEHOLDER'S ENGAGEMENT IN SERVICE DELIVERY PLANNING IN SOUTH AFRICA
Get PDFThis article examines stakeholder involvement in service delivery planning within local government, focusing on Polokwane Local Municipality. Local governments' proximity to stakeholders through integrated development planning (IDP) enables a comprehensive understanding of their needs. Municipalities are legally required to ensure active stakeholder participation, reflecting a governance model of "government of the people, by the people, and for the people." Drawing on Patsy Healey's (1997) collaborative planning theory, the article uses a mixed methodology, including probability sampling of 80 respondents for questionnaires and purposive sampling of 3 respondents for semi-structured interviews. Findings reveal a significant deficit in service delivery due to inadequate stakeholder engagement, despite satisfactory legislative compliance. Challenges include demonstrations, resource constraints, service backlogs, inadequate monitoring and evaluation, and corruption. Recommendations emphasize prioritizing stakeholder involvement and enhancing institutional capacity to optimize resources, address poverty, and improve service delivery

PERFORMANCE REQUIRED FOR COMMON-USE COMPONENTS OF COMPUTER NETWORKS
Get PDFSometimes, in practice, simple solutions of quick preliminary estimation of basic characteristics of a computer network are needed. In this aim, the backbone subnet and server set of wide area computer networks are examined. Based on Jackson’s partitioning theorem and considering the linear dependence of the costs of channels, routers, and servers on their performance, a simplified analytical model for these components of the network is defined. Using this model, two optimization problems are formulated: minimizing the average response time to user requests of data processing and minimizing the summary cost of servers, channels and routers of the computer network. For both problems, analytical solutions regarding the necessary performances of channels, routers and servers are obtained. As expected, in the obtained analytical solutions, the equations for the optimization criteria of the two problems coincide, only their form being different. Calculations of performances according to these solutions are simple and can be done, for example, in MS Excel. Because the obtained in this way performances are positive real numbers, and the allowed performances of concerned entities are discrete ones, further adjustment of the solution in question, depending of the case, may be necessary. For such an adjustment, two algorithms are proposed. One of them solves the problem by reducing it to that of backpack. Another solves the problem based on the use of resource concentration rule
ENSURING THE LONG-TERM STABILITY OF DEEP CUTTING SLOPES FORMED BY CLAY SOILS ON REPUBLIC OF MOLDOVA ROADS
Get PDFThe article presents research results on identifying the causes of landslide deformations along the M21 road, Brest-Chișinău-Poltava in the Republic of Moldova, using Maslov's physico-technical theory of creep, along with proposals for their stabilization. It highlights the geomorphological and geological characteristics contributing to landslide formation, focusing on the rheological properties of clayey soils. The studies included stability calculations based on laboratory investigations aimed at determining strength and rheological properties. Results demonstrated the dependence between soil moisture and structural cohesion, influencing landslide resistance and creep deformations. Proposed values for residual strength characteristics of clayey soils ensure long-term stability of deep excavation slopes without creep deformations, as well as values allowing economically feasible excavations with partial reduction of structural cohesion without compromising slope stability during operation
EVALUATING THE ADSORPTION POTENTIAL OF SUGARCANE BAGASSE AND LEMONGRASS FOR CHROMIUM (VI) REMOVAL IN WASTEWATER TREATMENT
Get PDFThe increasing levels of chromium (VI) ions in textile wastewater pose significant environmental challenges, necessitating effective treatment methods. This study evaluates the biosorption potential of sugarcane bagasse (SCB) and lemongrass (LM), both individually and in blend form, for the removal of chromium (VI) ions. Batch adsorption experiments were conducted to assess the impact of contact time and adsorbent dosage on removal efficiency. BET analysis revealed that the blend had the highest surface area (1047.885 m²/g), enhancing its adsorption capacity, while FTIR spectroscopy identified key functional groups such as hydroxyl and carbonyl that facilitate metal binding. Results indicated that the blend exhibited superior adsorption capacity, with kinetic studies showing that the adsorption process followed a Pseudo-second order model, suggesting chemisorption as the dominant mechanism. Isotherm analyses indicated that the Langmuir model best-described adsorption on SCB, while the Freundlich model was more suitable for LM and the blend. This research recommends the practical application of SCB and LM in wastewater treatment and encourages further investigation into their potential for removing other heavy metals, highlighting a sustainable approach to environmental remediation
INFLUENCE OF POTATO AND PEA PROTEIN FINING ON THE CHROMATIC PROFILE FEATURES OF RARA NEAGRA WINE
Get PDFDue to food security issues associated to use of animal proteins and the rising demand for non-animal-based fining agents, the wine industry is becoming more interested in developing alternatives to conventional protein fining. This study evaluated the effects of several protein fining agents on the color and phenolic content of Rara Neagra red wine. Wines that were fined with proteins from potatoes and peas were contrasted with gelatin treated wines and untreated control wines. Variations in color and phenolic content revealed that plant and animal proteins had different capacities for clarification and interaction with colorless phenolics and anthocyanins, which had significant effects on color characteristics. The experimental study revealed that, in comparison to gelatin, potato and pea protein extracts were more protective in lowering the overall polyphenol level of Rara Neagra wines. Similar to other proteinaceous fining agents, the acquired data demonstrated a minor decrease in color intensity and a low decrease in the quantity of total anthocyanins. Overall, results showed that potato protein and pea protein could be used as effective fining alternatives to animal proteins, and their effectiveness should be researched in different variations depending on the chemical composition or variety of the wines
INTEGRATION OF SPENT GRAIN INTO FOOD PRODUCTS
Get PDFSpent grain is a component of grain that consists primarily of its shells and is a by-product of the production of beer or ethyl alcohol. It is characterized by a diverse chemical composition, mainly composed of proteins and dietary fibers and, to a lesser extent, lipids, minerals, phenolic compounds, as well as B vitamins and vitamin E. In its native form, it is a product with a high moisture content, which makes it unsuitable for long-term storage. In this connection, several problems arise that worsen the economic and environmental situation at the global level. This article presents effective methods of processing spent grain to prevent negative consequences associated with its irrational use. Possibilities for the application of used spent grain in the food industry are also presented: bakery and pasta, confectionery, the meat and dairy industry, as well as the production of beverages. Thus, the integration of spent grain in the food composition will lead to solving the economic and environmental difficulties that have appeared in the last decades; it will allow the development of a functional food market, which will lead to the improvement of the quality of the population life by strengthening the trend of good nutrition and reducing the negative impact on the environment
CHARACTERISTICS OF BIOMASS RESULTING FROM AGRO-INDUSTRIAL PROCESSES AND POSSIBILITIES OF ITS EVALUATION IN THE CONTEXT OF THE CIRCULAR BIOECONOMY
Get PDFWaste management in the agro-industrial sector is a significant issue that demands a thoughtful and multifaceted approach, not only to prevent environmental contamination with harmful substances but also to produce value-added products. The selection of waste treatment technology should be based on the waste's nature, composition, and initial quantities, which are determined by the primary production cycle, raw materials, and applied conditions. This study focuses on exploring innovative methods to enhance the conversion rate and efficiency of organic waste biomass by incorporating small amounts of biologically active substances into the fermentation mix. The research also examines the impact of natural plant-based additives on various types of biomass within the agro-industrial sector. In agricultural areas where industries produce wine, spirits, beer, and juices, liquid waste is continuously produced in a state of ongoing digestion. This requires strict measures to prevent its direct disposal into landfills, water bodies, or other environmental compartments, as such actions could disrupt the natural balance of soil microorganisms, plants, and other organisms. Present-day methods for handling solid organic waste often include its application in agriculture, incineration, anaerobic digestion, composting, and related processes. Liquid waste from the agro-industrial sector can be treated through processes like sedimentation, settling, and anaerobic fermentation
CAUSES OF THE SPREAD OF PRIVATE TUTORING PHENOMENON A FIELD STUDY AT A CENTER IN ALGERIA
Get PDFThis research discusses the phenomenon of private tutoring, which has become a significant threat to the education system by creating academic inequalities and hindering students' equal opportunities for university enrollment. The study explores the prevalence of private tutoring at the secondary level in Ghardaia and investigates the reasons behind its widespread adoption. It also examines whether educational elements, such as teachers and the curriculum, influence the prevalence of private tutoring. Additionally, the research explores the role of families in encouraging their children to adopt this educational pattern. The descriptive-analytical methodology was employed, utilizing a questionnaire with 23 items distributed across three axes: reasons related to the student, reasons related to the teacher and curriculum, and reasons related to the family. The questionnaire was administered to a sample of individuals in Ghardaia. After analyzing the responses, the study found that the majority of the sample attributes the spread of private tutoring largely to reasons associated with the family, significant encouragement from families for their children to join private tutoring, and perceived teacher inadequacy in academic achievement. The dense curriculum was also identified as a crucial factor leading students to opt for private tutoring
