    Glycemic Index of Five Ghanaian Corn and Cassava Staples
    (2019-09-10) Yeboah, Eunice Serwaa; Agbenorhevi, K. Jacob; Sampson, Gilbert Owiah
    Glycemic index (GI) quantifies and measures the blood glucose raising effect of a food containing a specific amount of carbohydrate. Due to this concerns have been raised on the quality of carbohydrate and the indices that influence its metabolism. The objective of study was to investigate the effect of processing on the glycemic index of five Ghanaian corn and cassava staples. The research design was a cross over trial. Ten healthy subjects consisting of five males and five females were included in the study. Study subjects were served 50g of pure glucose containing 50g of available carbohydrate and 200ml of pure water. Glucose which served as the reference food was given to subjects on two different occasions. The subjects were also served specific 50g of abolo, akple, kafa, local kokonte and processed kokonte on specific days. The glycemic index figures were assessed by using official methods and reported as mean for the ten study subjects. Locally made kokonte had the least GI of 7 followed by processed kokonte which had a GI of 18 whiles kafa had a low GI of 29. Abolo had a medium GI value of 58 and akple also had a medium glycemic index value of 69. There was no significant difference between the GI of locally made kokonte and processed kokonte (p > 0.05) indicating processing had no significant effect on the GI of kokonte.

    IMPLEMENTATION OF SPEECH RECOGNITION IN POINT-OF-SALE SYSTEM
    (2023) POMETSEY STEPHEN KWAKU
    In today's fast-paced world, customers demand swift and convenient services, making it imperative for businesses to offer a friendly and user-friendly system to expedite the checkout process. Traditional cash registers have been largely replaced by Point-of-Sale Systems (POS Systems), which combine both software and hardware to record sales in real-time. However, with the advent of technology and artificial intelligence, there is a compelling opportunity to enhance the efficiency of POS systems even further. Speech Recognition (SR) and Natural Language Processing (NLP), which fall under the domain of Artificial Intelligence, facilitate human computer communication by enabling machines to understand and transcribe spoken language. This breakthrough offers an alternative input method to conventional keyboards and other hardware components. This thesis project aims to implement speech recognition technology in Point-of-Sale systems, reducing the reliance on traditional keyboard input method. The study poses two key research questions: whether Voice/Speech Recognition can effectively replace keyboard input in POS systems and how Voice/Speech Recognition can enhance service delivery in such systems. The research objectives include proposing speech recognition as a viable substitute for keyboard input and examining its impact on service delivery in POS systems. It addresses the practical application of speech recognition in point-of-sale systems using existing algorithms use in PHP, JavaScript (Ajax, jQuery) and MySQL with the help of Web Speech API, offering a novel approach to improve database interactions. In conclusion, this thesis explores the integration of speech recognition in Point-of-Sale systems as a means to optimize productivity and customer service, ultimately offering a valuable alternative to traditional input method.

    IMPROVEMENT TECHNIQUES IN THE GHANAIAN GARMENT INDUSTRY
    (2023) DORKEY MELODY
    This study examines improvement techniques in the Ghanaian garment industry using two fashion houses in the Ho municipality as a case study. The study adopts a descriptive research design to comprehensively understand the improvement techniques adopted by garment manufacturers in the Ho municipality. The target population for the study was all workers of the two fashion houses in the Ho municipality, and a census sampling method was used. Interviews and observations were used as the data collection methods, and the collected data were analysed using quantitative approaches. The purposive sampling technique was used to select a total of 78 participants; the two fashion houses were selected to participate in the study. Questionnaires and Interviews were used as the primary data collection instruments. The findings indicate that the most commonly used techniques for cutting and sewing were patternmaking and the round method of sewing, respectively. The study highlights the need for training and development programme for workers in the industry to enhance their skills in various improvement techniques and the use of technology, sustainable materials, and clear communication with clients to improve the industry’s competitiveness. It was thus recommended that fashion houses should use high-quality materials is particularly relevant to the context of Fashion Houses in Ghana, as it can help them to produce better quality garments that are more durable and attractive to customers.

    PRODUCTION OF BEADED ARTICLES FOR MASSAGE
    (2023) ASIBUO STELLA
    Massage beader articles are the articles that are used to exert pressure on the body. This pressure makes the body soft and relaxed thereby reducing pains in the cells of the body. The study seeks to highlight the production of beaded articles for message. The specific objectives were to identify the importance of beaded articles for massage, to produce beaded articles for massage and to evaluate beaded articles for massage to ascertain its usage. The qualitative research approach was used. Interview and observation were research instruments employed for data collection. The findings revealed that, the usage of beaded articles are of importance to the body. The articles produced are beaded massage mat, beaded massage sticks and beaded massage slippers. This project recommend that the massage beaded articles should be produced into small sizes and larger quantities so that people can use the articles to meet their health needs.

    INVESTIGATING CHALLENGES IN PATTERN MAKING FACED BY CLOTHING AND TEXTILES STUDENTS IN TECHNICAL AND VOCATIONAL SCHOOLS IN THE VOLTA REGION OF GHANA
    (2023) NUWORKPOR AFI ANITA
    Pattern making is a critical skill in the field of clothing and textiles, forming the foundation for successful garment design and production. This study explored the challenges faced by students in pattern making in technical and vocational schools in the Volta Region of Ghana. The research employed a mixed-methods design, incorporating surveys and semi-structured interviews with fifty-five respondents which comprises a mix of both students and instructors, selected through a combination of purposive and systematic sampling methodologies. The study found that, students possess a higher level of familiarity with pattern making approaches compared to their overall expertise on the subject matter, and that a significant proportion of the students exhibit competency in pattern drafting. However, their level of competence in this area is relatively insufficient, suggesting the necessity for further efforts to enhance the students' skills and competences in pattern drafting. In addition, the study found that a considerable proportion of the students exhibited a deficiency in the technical aptitude necessary for precise pattern drafting. Based on the findings, the study recommends the establishment of a stronger collaborative partnership between industry professionals and academics in order to critically evaluate and enhance the curriculum for pattern making courses. The partnership should aim to guarantee that the curriculum encompasses a wide array of pattern making procedures, encompassing both fundamental and intricate issues that students may potentially face.
