Human fatigue model at road transport

100%

Ullah I. , Szpytko J.

tom Vol. 17, No. 2

467-474

This paper presents detailed studies in relevance of fatigue. Diverse aspects of fatigue, like causality dala, risk factors and consequences have enlightened to address proper fatigue mechanism. Fatigue is going to be major issue in Asia, and has brought many deaths annually. Fatigue is a process that start s with risk factors, moves on to subjective perceptions of and concludes with the consequences of fatigue. Driver fatigue is recognized as a major causal faetor in accidents involving long-haul commercial drivers. Human operational performance and its relation with road safety is really great mean to understand in terms of technical and human behaviour. Fatigue risk factors, sleep, noise and working schedule etc like are also reduced with specific solution and personnel limits. Human error is found a basie reason of fatigue and need to be addressed to public and concerned authorities. Mathematical model and field based data is highly appreciated to understand basic scenario of subject and accident. The best way to reduce fatigue is to address issues publically and improve system according to environment of transport. This paper presents an introduction to the human fatigue model formulation and its application using a conception of the diserete time process that is regenerative with respect to the renewal process. The model can be used to estimate the human fatigue according to partial and full rest.

We investigated the association between scripture memorization and brain tissue using magnetic resonance imaging techniques. Participants comprised 63 healthy adults between the ages of 35 and 80 years old with no neurological or psychological disorders. Of these, 19 had completely memorized the Quran, 28 had partially memorized parts of Quran while 16, the control group, had not committed the Quran into their memory. White matter, grey matter and cerebrospinal fluid volumes were calculated. The brain tissue volumes of those who memorized the entire Quran and those who memorized only a small portion were compared with the control group using one‑way ANOVA implemented in SPSS. There was no significant effect of age between the three groups (p>0.50). The group who completely memorized the Quran had larger grey matter and white matter volumes than the control group. Our results showed that those who memorized scripture had more brain tissues preserved compared with those who had not memorized scripture. These findings suggest that engaging our brains by memorizing scripture may increase brain health.
