An Appraisal of Teachers’ Perception on Repairing of Clothes

Abstract The purpose of the study was to examine teachers’ perception on repairing of clothes in Agona Kwanyako in the central region of Ghana. Quantitative research approach and Descriptive survey design were adopted for this study. The population of this study comprised teachers in the seven public Basic Schools, one Senior High School, two private Basic Schools and one Vocational and Technical School in [...] Read more.
The purpose of the study was to examine teachers’ perception on repairing of clothes in Agona Kwanyako in the central region of Ghana. Quantitative research approach and Descriptive survey design were adopted for this study. The population of this study comprised teachers in the seven public Basic Schools, one Senior High School, two private Basic Schools and one Vocational and Technical School in Agona Kwanyako. Krejcie and Morgan chart was used to sample hundred and fifty-five (155) out of two hundred and sixty (260) teachers in Agona Kwanyako schools. The main instrument for data collection and analysis was questionnaire. All the questionnaires retrieved were prepared by sorting and coding. They were then entered into IBM SPSS Statistics 2017 version 25.0 for data to be analysed. The SPSS software was used to generate mean, standard deviation, frequency and percentages on the data because it is fast, energy saving and gives a consistent and accurate statistical representation of raw data. Findings were then discussed in relation to the research question for the study. Data were presented using tables and charts. The study indicated that the perception one holds about the repair of clothes affects how they view the act and their subsequent adaptation of the exercise. The perception teachers hold about clothes repair was that, clothes protect the environment, create employment and alleviate one from poverty, helps clothes stay trendy and can give one a sense of satisfaction. It can also be concluded that clothes that are normally used such as dresses, shirts and trousers are the types of clothes mostly repaired. Teachers have positive perception about clothes repair. Based on this it is recommended that Home Economics teachers should team up with other teachers to inculcate proper clothes care in their students. Also, clothes should be made in such a way that repairing is easier and possible based on the findings on the types of clothes that are mostly repaired.

Distributed Generation and Optimization of smart Grid Systems: Case Study of Kumba in Cameroon

Abstract The traditional electric grid of the City of Kumba has been experiencing a constant failure which leads inhabitant to experience constant blackout. This constant blackout persists and stays for a long time due to the lack of communication between equipment, consumer and supplier. Whenever there is a fault, the repairing agents walk along the feeder to find the fault. This manual fault finding [...] Read more.
The traditional electric grid of the City of Kumba has been experiencing a constant failure which leads inhabitant to experience constant blackout. This constant blackout persists and stays for a long time due to the lack of communication between equipment, consumer and supplier. Whenever there is a fault, the repairing agents walk along the feeder to find the fault. This manual fault finding increases the restauration time which leads to the augmentation of the blackout period. Factors responsible for the failure of the line are complex to be controlled. It is necessary to reduce restauration time by introducing Information and Communication Technologies (ICT) and sensing system in the grid and making it to be smart. ICT in this smart grid, sensors and smart meters are meant to assure two-way communication between the supplier and the consumer. They send real time information which is computed at the control center to optimize the entire grid. Distributed generation is also introduced in the system for two purposes. To complete the lag in power demand of the grid and to take over the supply when the main feeder is faulty. Various distributed generation sources studied led to the choice of solar power plants thanks to their low production of Greenhouse Gas (GHG) and availability of their resources in the city. A model has been proposed for the distributed generation and optimization of the smart grid. The system indexes obtained without distributed generation in the grid are different from that with. The difference in these indexes proved that the grid has been optimized. However, the reliability of the grid is enhanced after the introduction of distributed generation into the system. This enhancement in reliability declares that with distributed generation into the grid, the population of Kumba has a reliable power supply, which makes them to have energy throughout.
