    Some disabled artists in Ghana exhibit a lot of rich knowledge and practical skills which are potential materials for teaching and learning. These should be documented otherwise the rich concepts and philosophies inherent in them which, among others, are perceived to depict societal problems may be lost after their death. It is the aim of this paper to identify and document the unique artistic qualities in some of the art works of selected physically disabled artists. It was the pursuit of the writers to contribute to the documentation of these works to serve as resource material for Art Education and Special Education. Through qualitative research, an enquiry was made into the artifacts of six (6) selected disabled artists in Ashanti Region. Description of ten (10) works comprising textiles, sculpture, painting, three dimensional (3-D) design, and basketry was done. These physically disabled artists were interviewed using the face-to-face method as data collection instrument. The results of the research largely confirm  that the selected artifacts depict problems of the society. Also, a few of the works portray their emotions, personal nature, ideas and philosophy. It is recommended that more physically disabled persons should find life in art since art provides varying types of employment for disabled persons.Keywords: Artifacts, art education, philosophy, disability art

    This study investigates and explores avenue for effectively managing and increasing the availability of Graduate Students’ scholarship by submitting Theses and Dissertations in electronic format for easy accessibility and storage. This pilot study was done in the year 2009 with GraduateStudents in the Faculties of Fine and Industrial Art in the Kwame Nkrumah University of Science and Technology (KNUST). Qualitative research was employed to appraise and analyse Theses and Dissertations (TDs) management in the School of Graduate Studies (SGS) and theUniversity Library. In addition, graduate students’ knowledge of online publishing and the capabilities of the Network Operations Centre (NOC) of the KNUST in managing the Electronic Theses and Dissertations (ETDs) were reviewed. An online framework resource was designed anddeveloped to manage and promulgate graduate research output in the structure of ETDs. This framework named “KNUSTVester” is founded on the philosophy of Open Access (OA) Initiative and mimicked the submission processes of the SGS and employed the Dublin Core MetadataElement Set (DCMES) for accessing the ETDs online. Testing of the online framework resource was done and the results confirmed that the submission of theses and dissertations electronically could be an effective tool for the promulgation of knowledge and skills in this 21st Century

    The aim of this paper is to identify the essential and vital information about body proportions, body assets and body liabilities so as to realize the good features to emphasize and the flaws to improve through effective optical illusions in clothing. This study was based on the premise that many people disregard their proportions and figure types and just go for any style of dress that may not befit them. In order to achieve the above aim, pertinent literature was reviewed, and interviews conducted to investigate whether or not people consciously select their clothes on the basis of their body proportions. Thirty (30) ladies were interviewed and observed. The result was that the population studied was not individualistic in their dresses. The people had diverse criteria for selecting their clothes which largely excluded consideration of their body proportions. In discussing the results, personality analysis chart was designed for use of fashion conscious persons. This is in relation to the proportions of identified fashion models, average figures and some philosophy on ideal beauty. Besides, design elements which serve as effective tools for optical illusions and recommended design ideas for shaping selected figures have been provided to guide people to go for the most appropriate dress styles that are distinct and individualistic. Keywords:Proportion, personality analysis, optical illusion, distinct dressing. Journal of Science and Technology Vol. 28 (2) 2008: pp. 133-14

    Diorama Art – A Potential Medium For Museum Educationm

    Get PDF
    The study recognizes the traditional role diorama plays as an effective medium for museum education and employed both descriptive and experimental methods to produce a diorama to popularize it for the Ghanaian populace. It explored the use of non-traditional modelling material (corn shucks and cobs) in the preparation of diorama. The results of the study  indicate that corn shucks and cobs which have less use in our environment as raw materials can be used as modelling medium to produce sculpture. As such other unconventional materials could be explored for modelling in order to open more avenues to sculptors. Besides, diorama could be a minimuseum, a potent tool to keep proper records, document valuable cultural and historic information to inspire and educate the public; as well as a way of building museums on school campuses to expand classroom teaching and learning.Keywords: Diorama, Museum, Education, Aperture, Assemblage

    Analysis of drug resistance among difficult-to-treat tuberculosis patients in Ghana identifies several pre-XDR TB cases

    BACKGROUND: Resistance to tuberculosis (TB) drugs has become a major threat to global control efforts. Early case detection and drug susceptibility profiling of the infecting bacteria are essential for appropriate case management. The objective of this study was to determine the drug susceptibility profiles of difficult-to-treat (DTT) TB patients in Ghana. METHODS: Sputum samples obtained from DTT-TB cases from health facilities across Ghana were processed for rapid diagnosis and detection of drug resistance using the Genotype MTBDRplus and Genotype MTBDRsl.v2 from Hain Life science. RESULTS: A total of 298 (90%) out of 331 sputum samples processed gave interpretable bands out of which 175 (58.7%) were resistant to at least one drug (ANY(r)); 16.8% (50/298) were isoniazid-mono-resistant (INH(r)), 16.8% (50/298) were rifampicin-mono-resistant (RIF(r)), and 25.2% (75/298) were MDR. 24 (13.7%) of the ANY(r) were additionally resistant to at least one second line drug: 7.4% (2 RIF(r), 1 INH(r), and 10 MDR samples) resistant to only FQs and 2.3% (2 RIF(r), 1 INH(r), and 1 MDR samples) resistant to AMG drugs kanamycin (KAN), amikacin (AMK), capreomycin (CAP), and viomycin (VIO). Additionally, there were 4.0% (5 RIF(r) and 2 MDR samples) resistant to both FQs and AMGs. 81 (65.6%) out of 125 INH-resistant samples including INH(r) and MDR had katG-mutations (MT) whereas 15 (12%) had inhApro-MT. The remaining 28 (22.4%) had both katG and inhA MT. All the 19 FQ-resistant samples were gyrA mutants whereas the 10 AMGs were rrs (3), eis (3) as well as rrs, and eis co-mutants (4). Except for the seven pre-XDR samples, no sample had eis MT. CONCLUSION: The detection of several pre-XDR TB cases in Ghana calls for intensified drug resistance surveillance and monitoring of TB patients to, respectively, ensure early diagnosis and treatment compliance

    Cholera remains a major global public health threat and continuous emergence of new Vibrio cholerae strains is of major concern. We conducted a molecular epidemiological study to detect virulence markers and antimicrobial resistance patterns of V. cholerae isolates obtained from the 2012-2015 cholera outbreaks in Ghana. Archived clinical isolates obtained from the 2012, 2014 and 2015 cholera outbreaks in Ghana were revived by culture and subjected to microscopy, biochemical identification, serotyping, antibiotic susceptibility testing, molecular detection of distinct virulence factors and Multi-Locus Variable-Number of Tandem-Repeat Analysis (MLVA). Of 277 isolates analysed, 168 (60.6%) were confirmed to be V. cholerae and 109 (39.4%) isolates constituted other bacteria (Escherichia coli, Aeromonas sobria, Pseudomonas aeruginosa, Enterobacter cloacae and Enterococci faecalis). Serotyping the V. cholerae isolates identified 151 (89.9%) as Ogawa, 3 (1.8%) as Inaba and 14 (8.3%) as non-O1/O139 serogroup. The O1 serogroup isolates (154/168, 91.7%) carried the cholera toxin ctxB gene as detected by PCR. Additional virulence genes detected include zot, tcpA, ace, rtxC, toxR, rtxA, tcpP, hlyA and tagA. The most common and rare virulence factors detected among the isolates were rtxC (165 isolates) and tcpP (50 isolates) respectively. All isolates from 2014 and 2015 were multidrug resistant against the selected antibiotics. MLVA differentiated the isolates into 2 large unique clones A and B, with each predominating in a particular year. Spatial analysis showed clustering of most isolates at Ablekuma sub-district. Identification of several virulence genes among the two different genotypes of V. cholerae isolates and resistance to first- and second-line antibiotics, calls for scaleup of preventive strategies to reduce transmission, and strengthening of public health laboratories for rapid antimicrobial susceptibility testing to guide accurate treatment. Our findings support the current WHO licensed cholera vaccines which include both O1 Inaba and Ogawa serotypes

    Genotypic and phenotypic diversity of Mycobacterium tuberculosis complex genotypes prevalent in West Africa

    Findings from previous comparative genomics studies of the Mycobacterium tuberculosis complex (MTBC) suggest genomic variation among the genotypes may have phenotypic implications. We investigated the diversity in the phenotypic profiles of the main prevalent MTBC genotypes in West Africa. Thirty-six whole genome sequenced drug susceptible MTBC isolates belonging to lineages 4, 5 and 6 were included in this study. The isolates were phenotypically characterized for urease activity, tween hydrolysis, Thiophen-2-Carboxylic Acid Hydrazide (TCH) susceptibility, nitric oxide production, and growth rate in both liquid (7H9) and solid media (7H11 and Lowenstein-Jensen (L-J)). Lineage 4 isolates showed the highest growth rate in both liquid (p = 0.0003) and on solid (L-J) media supplemented with glycerol (p<0.001) or pyruvate (p = 0.005). L6 isolates optimally utilized pyruvate compared to glycerol (p<0.001), whereas L5 isolates grew similarly on both media (p = 0.05). Lineage 4 isolates showed the lowest average time to positivity (TTP) (p = 0.01; Average TTP: L4 = 15days, L5 = 16.7days, L6 = 29.7days) and the highest logCFU/mL (p = 0.04; average logCFU/mL L4 = 5.9, L5 = 5.0, L6 = 4.4) on 7H11 supplemented with glycerol, but there was no significant difference in growth on 7H11 supplemented with pyruvate (p = 0.23). The highest release of nitrite was recorded for L5 isolates, followed by L4 and L6 isolates. However, the reverse was observed in the urease activity for the lineages. All isolates tested were resistant to TCH except for one L6 isolate. Comparative genomic analyses revealed several mutations that might explain the diverse phenotypic profiles of these isolates. Our findings showed significant phenotypic diversity among the MTBC lineages used for this study

    Host-switching by a vertically transmitted rhabdovirus in Drosophila

    A diverse range of endosymbionts are found within the cells of animals. As these endosymbionts are normally vertically transmitted, we might expect their evolutionary history to be dominated by host-fidelity and cospeciation with the host. However, studies of bacterial endosymbionts have shown that while this is true for some mutualists, parasites often move horizontally between host lineages over evolutionary timescales. For the first time, to our knowledge, we have investigated whether this is also the case for vertically transmitted viruses. Here, we describe four new sigma viruses, a group of vertically transmitted rhabdoviruses previously known in Drosophila. Using sequence data from these new viruses, and the previously described sigma viruses, we show that they have switched between hosts during their evolutionary history. Our results suggest that sigma virus infections may be short-lived in a given host lineage, so that their long-term persistence relies on rare horizontal transmission events between hosts

    Genomic epidemiological analysis identifies high relapse among individuals with recurring tuberculosis and provides evidence of household recent TB transmission in Ghana

    Get PDF
    OBJECTIVE: We investigated the cause of recurring tuberculosis (rcTB) among pulmonary TB participants recruited from a prospective population-based study conducted between July 2012 and December 2015. METHODS: Mycobacterium tuberculosis complex isolates obtained from rcTB cases were characterized by standard mycobacterial genotyping tools in addition to whole genome sequencing, followed by phylogenetic analysis to assess strain relatedness. RESULTS: A greater proportion (58.3%, 21/36) of individuals with rcTB episodes had TB recurrence within 12 months post treatment. Only 19.4% (7/36) of participants with rcTB harbored a strain with isoniazid (INH) resistance at baseline of which 29% (2/7) were additionally resistant to rifampicin. However, 27.8% (10/36) harbored an INH resistant strain upon recurring of which 40% (4/10) were MDR-TB strains. Recurrent TB was attributed to relapse (same strain) in 75.0% (27/36) of participants with 25.0% (9/36) attributed to re-infection. CONCLUSION: Our findings indicate that unresolved previous infection due to inadequate treatment may be the major cause of rcTB

    Culex pipiens development is greatly influenced by native bacteria and exogenous yeast

    Get PDF
    Culex pipiens is the most cosmopolitan mosquito of the Pipiens Assemblage. By studying the nature of interactions between this species and microorganisms common to its breeding environment we can unravel important pitfalls encountered during development. We tested the survival rate of larval stages, pupae and adults of a Cx. pipiens colony exposed to a variety of microorganisms in laboratory conditions and assessed the transmission to offspring (F1) by those organisms that secured development up to adulthood. Three complementary experiments were designed to: 1) explore the nutritional value of yeasts and other microorganisms during Cx. pipiens development; 2) elucidate the transstadial transmission of yeast to the host offspring; and 3) to examine the relevance of all these microorganisms in female choice for oviposition-substratum. The yeast Saccharomyces cerevisiae proved to be the most nutritional diet, but despite showing the highest survival rates, vertical transmission to F1 was never confirmed. In addition, during the oviposition trials, none of the gravid females was attracted to the yeast substratum. Notably, the two native bacterial strains, Klebsiella sp. and Aeromonas sp., were the preferred oviposition media, the same two bacteria that managed to feed neonates until molting into 2nd instar larvae. Our results not only suggest that Klebsiella sp. or Aeromonas sp. serve as attractants for oviposition habitat selection, but also nurture the most fragile instar, L1, to assure molting into a more resilient stage, L2, while yeast proves to be the most supportive diet for completing development. These experiments unearthed survival traits that might be considered in the future development of strategies of Cx. pipiens control. These studies can be extended to other members of the Pipiens Assemblag
