Background: Working environment is one of the factors which can determine public health conditions as many workers spend a large portion of their time at work.Objective: The aim of this study was to assess the magnitude and characteristics of occupational injury among workers in Kombolcha textile factory, North East Ethiopia.Methods: Institution based cross-sectional study design was conducted from April1-15, 2013 among 455 randomly selected workers after stratification by working departments. A structured questionnaire based interview, review of records of injury report and walk through survey using work environment observation checklist were used to support the self-reported information. Descriptive statistics were used for analysis using SPSS version 20.Results: The overall occupational injury prevalence rate was 36.9%. Puncture, abrasion/laceration, fracture, cut and back pain were the most common types of injury. Most of the sources of injury were due to machinery, lifting heavy objects, splinters, fall and hand tools.Conclusion: The magnitude of occupational injury at Kombolcha textile industry showed a high prevalence that indicates the need to work on integrated injury prevention by mainstreaming occupational health and safety procedures in all working  departments of the factory.

ObjectivesTo guide the development of targeted interventions for the prevention of work-related back pain, this manuscript estimates the prevalence of back pain and its association with a variety of risk factors among Almeda textile factory production works from March to April 2015. An institutional—based cross-sectional study was carried out in Almeda textile factory, North Ethiopia. Randomly selected workers were administered a structured questionnaire about their socio-economic status, lifestyle, working conditions, back pain and selected risk factors. The data was entered to Epi Info 3.5.4 version and analyzed using SPSS version 16. Descriptive statistics were done to characterize the study participants. Bivariate and multiple logistic regressions were fitted to control confounding variables. Adjusted odds ratio with 95% confidence intervals was computed.ResultsThe prevalence of work-related musculoskeletal disorders was 53.1%. Gender, age, years of service, lack of physical activity, unavailability of adjustable chair, work-load and poor light were significantly associated with increased risk of back pain. The high prevalence of work-related back pain disorder implies that; habit of doing physical exercise, availing adjustable chair and light at the working place, are key issues which require specific interventions.Electronic supplementary materialThe online version of this article (10.1186/s13104-018-3440-4) contains supplementary material, which is available to authorized users.

Background Road traffic injury is one of the persistent public health challenges in most regions of the world, representing substantial human and economic losses. Annually, about 1.25 million lives are lost, whereas 50 million suffer from road traffic injuries globally. It has been shown that over 60% of the reasons for traffic injuries are a risky driving behavior (RDB). Despite the problem’s pervasiveness, there is a paucity of information about level and factors influencing RDB among professional car drivers in Bahirdar city, northwest Ethiopia. Methods An institution-based cross-sectional study was conducted from February to March 2016. A systematic random sampling technique was used to select 376 participants. A self-administered driver behavior questionnaire (DBQ) was used for data collection. We performed a binary logistic regression analysis to investigate the associations of variables. Potential confounders were controlled using a multivariable logistic regression model. We ascertained the significance at < 0.05 p value and evaluated strength of associations using crude odds ratios (COR) and adjusted odds ratios (AOR) with 95% confidence intervals (CI). Results A total of 361 drivers participated (response rate, 96%). The mean age was 34 (standard deviations ± 7.97) years. The majority, 98.9% ( N = 357), were males. The level of risky driving behavior and road traffic crashes were 79.4% (95% CI 75.92, 83.97) and 16.3% (95% CI 15.91, 24.84), respectively. Average monthly salary [AOR 2.04; 95% CI (1.23, 2.74)], driving experience [AOR 2.72; 95% CI (1.07, 6.89)], distance driven per year [AOR 2.06; 95% CI (1.13, 4.10)], and previous history of involvement in traffic crashes [AOR 2.30; 95% CI (1.15, 7.35)] were significantly associated with risky driving behavior. Conclusions The study shows that risky driving behavior is common among professional car drivers in the study setting. Therefore, it is strongly advisable for policy makers and other stake holders to devise strategies that consider working conditions, like monthly salary and driving experiences. The study also suggests that it is often advisable to reduce the distance driven per year and learn from implications of previous history of involvement in traffic crashes.

Objective. The aim of this research was to compare blood lead level of childbearing women near Addis Ababa-Adama highway with those who live far from it.Study Design. A comparative cross-sectional study design was used to compare blood lead levels of 40 childbearing women (study group) who lived relatively near Addis Ababa-Adama highway and other 36 childbearing women (comparative group) who lived relatively far (10 km) from the highway.Methods. In the study, women having a fertile age within 15–49 years were considered as “childbearing women.” Blood samples were collected from each group and analyzed for blood lead level comparison.Result. The study indicated significant blood lead level difference (p<0.001) between the groups. The study group had higher blood lead level (34.32 ± 6.39 μg/dL) than the comparative group (8.47 ± 3.01 μg/dL). The mean blood lead level of both groups was higher than the advised blood lead concentration for a woman to avoid occupational or vocational lead exposure.Conclusion. This study concluded that blood lead level of women who lived relatively near Addis Ababa-Adama highway was significantly higher than those who lived relatively far from the road.

This study focused in investigating the fuel properties of Castor oil Methyl Ester (CME) and its blend with diesel fuel in running a diesel engine. Engine tests have been carried out with the aim of obtaining comparative measures of torque, power, and specific fuel consumption. Castor oil was extracted by using a mechanical pressing machine and trans-esterification was made by methyl alcohol and potassium hydroxide as a catalyst.  So that its viscosity and density were reduced and by increasing its volatility.  By following the procedures given in American Society for Testing and Materials (ASTM) book the fuel characteristics were identified whether it fulfil the requirements needed to be used as a fuel in internal combustion engines or not. From the characterization result, it was proved that trans-esterified castor oil was found to be a promising alternative fuel for compression ignition (diesel) engines. But the viscosity of CME was still higher and the energy content was a little bit less as compared to petro diesel. To solve these problems CME was blended with petro diesel in some proportion (B5, B10, B20, B40, B80). The torque, power and brake specific fuel consumption performances of CME and its blends with petro diesel were tested in a four stroke diesel engine. The analyzed results were compared with that of petro diesel and found to be very nearly similar, making CME a suiTable alternative fuel for petro diesel.

The purpose of this article is to provide an overview of the crossinstitutional assessment of sustainable development practices in the University of Gondar (UoG). The focus of the assessment was the level of UoG academic departments' integration of sustainability concerns in teaching, research and community service. Management contributions to sustainable development, student initiatives on sustainability issues and policy statements about sustainable development of UoG were also considered in the assessment.The data collection was based on the Unit-based Sustainability Assessment Tool (USAT); in addition, supplementary information was collected through observations across the four campuses of UoG from January to February 2012.The result of the assessment showed that only a few academic departments have incorporated sustainability concerns in their curricula and teaching approach. The initiation and commitment of academic departments in mainstreaming sustainability concerns in the research and community service delivered were relatively poor. The operation and management of UoG showed inadequate sustainable development practices on waste management, energy utilization and purchasing from
