This research is aimed at exploring students' perception on learning writing skills based on Project-based learning (PBL) method. The researcher applied descriptive research design for this study. A questionnaire was designed to find out the student's perception after they had been taught writing skills through PBL for a semester of 3.5 months. Thirty-five students in class 11 Mathematics at Ha Long high school for gifted students participated in the study. The result of this study showed that project-based learning provides immense opportunities for students to develop their writing skills. The students felt more confident in their ability to write, to work with others and to clearly communicate information. In addition, they enjoyed being an active participant in the learning process and assignments and activities in PBL were helpful. Findings from the study suggest that when guiding groups to implement projects, teachers need to make requirements on objectives, set of content-oriented commands, scale, implementation process and products of the project. The plans of the groups are discussed, unified with the teachers and recorded in each individual project. It is also necessary to ask students to clarify the benefits, difficulties encountered and remedies, new ideas for developing the project are born during the implementation of the project by the team.

Socialism has been presented as one of the notions which is difficult to be understood in a comprehensive manner. The most important articulation about socialism is the fact that it is about human relations. This aspect is fundamentally in connection with the concept of care for each other as well as the spirit of sharing of earthly privileges which are God's given gifts to the humanity for its survival. What make socialism an issue of human concern is therefore, the struggle to understand on whether human beings are self-sufficient or to be human implies to be in a mutual dependence as ends themselves and not means an end. However, in reference to the values which African socialism propagates, provides a unified platform for a perfect human relation.

The Fourth Industrial Revolution (4IR) has introduced significant changes to the global telecommunications industry including South Africa. As a result of innovations and changes in digital technology, the South African telecommunications industry is actively adopting the latest applications and processes of digital technology for rendering efficient voice, data and text messaging services to clients. These changes present opportunities for growth in marketshare to telecommunications operators. The paper presents a summary of the main impact of 4IR on the South African telecommunications industry along with challenges and opportunities 4IR presents to the industry. Advanced applications emanating from 4IR are characterised by the integration of new technologies such as artificial intelligence (AI), the Internet of Things (IoT), big data, and cloud computing. These technologies enable the telecommunications industry to offer innovative services and products, improve operational efficiency, and enhance customer experience. However, the implementation of 4IR technologies presents challenges such as cybersecurity risks, the need for upskilling the workforce, and regulatory challenges. Despite these challenges, 4IR technologies offer opportunities for the telecommunications industry to drive economic growth, increase productivity, and create new jobs. This abstract concludes that South African telecommunications companies need to embrace 4IR technologies to remain competitive in a rapidly evolving market.

Wind erosion and salt–affected soils are predominant desertification processes in Sudan, particularly in the northern part, and have adverse impacts on agricultural lands in the arid and semi-arid lands characterized by erratic rainfall, high temperature, high wind velocity and consequent high rates of evapotranspiration. The main objective of this paper is to present research review on combating, control, reclamation and management practices in areas affected by wind erosion and salt–affected soils. The study showed that the principal measures for controlling wind erosion depends on minimizing certain conditions that can be accelerated wind erosivity (winds ≥ 5.4 m/sec) and vice versa maximizing soil erodibility by creation a suitable condition for generate of non–erodible soil particles (NEP) versus soil surface detachment and transport by wind. Wind erosion research requires high financial support, thus this cost should be borne by government. The strategy of management practices of saltaffected soils aimed to sustain a level of salinity tolerable to the cultivated crops through good manages to water and crop. Assessment and mapping of wind erosion and salt-affected soils is urgent need to determine the inherent risk in the affected areas included in investment map of agricultural land capabilities of the country. Encourage studies on stabilizing soil particles by various natural or synthetic cementing and flocculation materials which are friendly to soil environment to increase NEP on the soil surface. Practical programs on reclamation of salt–affected soils should be included in national development programs and national strategy for scientific research in the State.

The study was conducted to assess the existing supply chain for mudcrab in Region 10 and to identify areas for improvement. The study covered major mudcrab producing areas in Region 10. Reconnaissance survey, courtesy calls and visits to the Local Government Units, Bureau of Fisheries and Aquatic Resources, and Department of Agriculture Offices in the mudcrab producing areas were done to identify the study sites. Results revealed that almost half (49.42%) of the mudcrab production in the country is from Region 10 which were majority caught/sourced from Panguil Bay. There are four specific supply chains traced. Computation of the marketing cost and margin for each key player revealed that the profit margin is higher towards downstream key players (traders). Also, the shorter the supply chain the more equitable distribution of income is observed. There is no face to face interaction between the local traders and the metro manila traders which resulted to information asymmetry. Some of the issues included mortality of mudcrabs during transport, price fluctuation, opportunistic behavior of the fisherman, and political intervention. Finally, common perception of the interviewed respondents pointed out that mudcrab supply is decreasing in Region 10. Therefore, the need for further intervention project on the production technology/ reinforcement of mudcrab industry should be done.

Kruger National Park (KNP) is a major destination for domestic and international visitors and plays a significant role in tourism and nature conservation. However, KNP is increasingly facing stiff competition from local and regional players. Therefore, KNP needs to deliver quality services to ensure visitors’ satisfaction and remain competitive by comprehending factors influencing visitors’ satisfaction. If KNP is to develop effective strategies to improve visitors’ satisfaction, prioritising key success factors (KSFs) that determine customer satisfaction is a prerequisite. This study, therefore, aims to identify the KSFs that KNP needs to prioritise in managing customer satisfaction. In order to achieve this, data were collected from 227 KNP visitors using a questionnaire and analysed using logistic regression. Logistic regression analysis was used to estimate the KSFs in managing customer satisfaction with the quality of service delivered at KNP. This study identified eight KSFs that determine the visitor’s satisfaction with the services; safety, wildlife experience, availability of information, booking experience, guiding experience, accommodation, facilities, and direction and signage.

Sound proof generating sets are normally associated with higher power output and it is costly. This is not commonly found in small generating sets as there are often acquired by low income earners and yet they desire the some comfort. This research focuses on the development of a new composite muffler for small generating sets. The design combined the principles of reactive and active noise reduction approach. The newly designed muffler was compared with an existing design and its performance evaluated. Performance tests show an improvement in terms of insertion loss and transmission loss and a reduction in back pressure build-up in the generating set. The average overall efficiency of the existing muffler is 43.28% whereas that of the newly designed composite muffler is 55.83%.The designed composite muffler provides the gasoline generating set with an additional noise reduction (attenuation) of 17.33 dB, reduced back pressure build-up of 3.6 kPa and improvement of 12.09% overall engine efficiency.
