    Assessment of Health and Safety Management in Constructing High-rise Buildings in Addis Ababa: The Case of Sunshine Construction Plc
    (Addis Ababa University, 2022-06) Desta Fekadu; Wasihun Mohammed (PhD)
    The existing health and safety measures employed in the construction of high-rise structures in Addis Ababa that are constructed by sunshine construction plc, were evaluated in this study. The study has given importance to health and safety concerns that have been overlooked by the building industry. A descriptive research design was adopted in this study. Questionnaires were provided and 87.5 percent of the example company's employees had responded. A total of 56 employees from the example firm were surveyed. The data gathered from the surveys were analyzed primarily using descriptive statistical analysis. SPSS version 21 software was used to evaluate and analyze the data, which was imported into Excel. The study had discovered that, the necessary safety and health training is not given to construction workers on how to manage safety and health practices on high rise building projects of the study area. Top officials in construction projects doesn’t give special attention on the implementation of safety training for construction workers in high rise buildings of the study area. Also there is gap on controlling system of, if safety training is implemented on construction site. The safety training program also doesn’t have a planned schedule as other high-rise building projects activities. According to the researcher, every real estate company should have an internal health and safety policy, designated personnel, appropriate facilities, and personal protective equipment (PPE) for all workers on the job site, and should include health and safety duties in contracts with outside contractors. Client of project should not only concentrate on finishing their project on time and schedule additionally they must be concerned protecting their construction workers from any hazard that may cause severe accident or death

    Study on Mycobacterium Bovis Using Conventional and Molecular Methods in Cattle Slaughtered in Kombolcha Elfora Meat Processing Plant
    (2008-06) Desta Fekadu; Yilkal Asfaw
    A cross-sectional study was conducted on 1138 heads of cattle at Kombolcha ELFORA meat processing plant, South-Wello Administrative Zone, Amarha Regional State from November 2007 to May 2008. The objectives of the study were to estimate the prevalence of bovine tuberculosis in cattle slaughtered at Kombolcha ELFORA meat processing plant, and to isolate and characterize the strains of mycobacteria from tuberculousis suspicious lesions. Detailed post mortem examination, bacteriological culturing, regions of difference-bases polymerase chain reaction and spoligotyping were used. The prevalence of bovine tuberculosis was 5.0 % (57/1138) in cattle slaughtered at Kombolcha ELFORA meat processing plant on the basis of detailed post-mortem examination. There was no significance difference in prevalence between male and female (P > 0.05), as well as among the age groups (P > 0.05). Mycobacteria were able to be isolated from 28 of the 57 cattle with gross lesion. A total of 49 isolates were recovered from the different tissues of these 28 cattle, and 20 isolates showed signal for M. tuberculosis complex species of which 19 were M. bovis while one isolate was M. tuberculosis. Further characterization of the strains of M. bovis using spoligotyping revealed the presence of five different cluster of spoligotyping pattern, which include Ethiopian M. bovis train 1, SB1176, SB0134, SB0133 and new strain. The binary number representation of the new strain is 1100000101010110111111111111111101111100000 where 1 indicates the presence of a spacer and 0 indicates a loss. The new spoligotyping was not reported previously from elsewhere to the M. bovis database (www.mbovis.org). The findings of this study indicated that tuberculous lesions were common in cattle slaughtered at Kombolcha ELFORA meat processing plant, and hence detailed post mortem meat inspection procedures are required to minimize the risk of its transmission to the public through meat consumption. In addition, appropriate cooking of meat is required before consumption.
