Anthropometric characteristics of roadside auto-mechanics: a case study
The study evaluated the relevant/corresponding anthropometric
characteristics of the people involved in engine-repair activities. The study was
carried out on the selected roadside auto-engine repairers along Lagos-Ibadan
express way, in Nigeria. This was with a view to providing ergonomic design
data for optimal working condition among this set of workforce and redesigning
the mechanics inspection-pit. Material and methods: The static and the
functional anthropometric characteristics of the mechanics were measured. The
data obtained from 110 auto-mechanics, randomly selected, were employed to
evaluate efficient design parameter for roadside workstations. Results: The
results indicated that inspection-pit is about 1626 mm deep; seat height ranges
between 375 mm and 405 mm; optimal work posture sitting is between 483 mm
and 622 mm. Conclusions: Adopting the data presented in this paper in
optimizing the auto-mechanics working conditions for effective workplace
comfort and productivity among the roadside auto-mechanics in Nigeria will be
of immense advantage
Simulation study of typical auto-mechanics tasks
This study evaluates the heart rate of healthy non-mechanics handling
predetermined loads, in postures typically used by roadside auto-mechanics
during repair. The heart rate for different age groups and work postures of
roadside auto-mechanics were determined from the assessment of healthy
non-mechanics of the same age limit using a digital premium pressure
monitor. Regressions were then developed to predict the heart rates of the
auto-mechanics. The result indicated that load and posture adopted by
roadside auto-mechanics, accounts for 2.74% and 4.51% of increase in their
heart rate respectively, while age accounts for 65.78%. It further revealed that
heart rate increases with age and load handled, and also showed that heart rate
is highest in bending posture, followed by stooping. In conclusion the
developed regression algorithms were sufficiently adequate in predicting the
heart rate of roadside auto-mechanics and it also indicated that older roadside
auto-mechanics need not engage in arduous tasks
Sustainable Manufacturing in Africa: The Pros and Cons- A Pragmatic Review
Manufacturing is an essential aspect of every thriving economy. It is a driver that cannot be overemphasized. This is so because production of goods and service is what ensures a continuous growth of the economy. It is therefore imperative to ensure the sustainability of this key tool. This study reviews the various elements of manufacturing, the strengths and constraints of sustainable manufacturing especially in Africa. The study concludes that manufacturing is sustainable provided the needed support from key players is available and can drive an economy to fast development
