Item Assessment Of The Diagnostic Performance Of HIV Rapid Test Kits In Ghana(University of Ghana, 2017-07) Okyere, D.A.Rapid diagnostic test kits are a crucial component of HIV diagnosis in resource limited settings. HIV RDTs are recommended because they are less expensive, require little expertise, require little sample volume and generate results in less than 20 minutes. The WHO, CDC, and UNAIDS recommend countries to undertake pre and post market evaluations of HIV RDTs used for HIV testing in that particular country. Little is known about post market evaluations of test used in Ghana. Most of these test kits are used as single test in HIV prevention and control programmes. To strengthen HIV screening in Ghana, a laboratory-based cross sectional analytic study was conducted using 200 HIV positive and HIV negative banked samples from the National Public Health Reference Laboratory of The Ghana Health Service at the Korle Bu Teaching Hospital. The sensitivity of the First Response, Wondfo, Healgen, Advance Quality (Intec) and Fastep test kits were 99.0% each. Advance Quality (Intec) demonstrated a sensitivity of 97%. The specificity of the First Response, Wondfo, Healgen, Advance Quality (Intec) and Fastep test kits were 92.0%, 95.0%, 98.0%, 99.0% and 95.0% respectively. The study results show that the test kits evaluated are good for screening purposes.Item Development of Brass Band Music of The Salvation Army, A Study of The Mamprobi Corps(University of Ghana, 2016-07) Okyere, D.A.This study focuses on the history and development of brass band music of the Salvation Army specifically Mamprobi Corps from the 1993 to 2016. The thesis takes a critical look at: the traditional performance practice, questions and resources of orality and modes of transmission, styles, type of instruments, transcriptions and analysis of some selected music performed by the band currently. The field recordings and the musical transcriptions of selected musical items clarify and support the research of the interplay of tradition, creativity, improvisation, innovation and the place of oral-aural modes of learning and performance, and stylistic traits in historical perspectives. Furthermore, the study examines the role brass band plays in the church, and non-church contexts, continuity and change. Finally, the research discusses the relevance of the Mamprobi Corps band today.
