[Articles]Planetary Urbanisation with or without Cities
Thierry Paquot 부산대학교 한국민족문화연구소 2011 Localities Vol.- No.1
In order to analyse the different kinds of global urbanization and to explore the challenge beneath it, the author describes the three phases of City History. The first city grew from the farming surplus and their destiny was tied to the farming economy. The rise of the capitalism in 16th century call for a new era. The City became mainly places of market trade. The industrial revolution was the third milestone, which we are just leaving now entering in the globalization. The author lists the five urban shapes: the slum, the megapolis, the world-sized city, the gated community, and the small and medium city. He also notices the existence of diffusing urban base on each continent. The challenges are numerous and highly tangled. The author suggests to combine the four main questions that every human being asks themselves about, the social question, the urban question, the knowledge question and the environmental question. I then conclude by opening a few leads for an ecological urbanization on various scales.

Predicting telemedicine system user satisfaction in Sub-Saharan Africa

During our literature review and on-site research in developing countries, particularly in Sub-Saharan Africa, we could not point out any efforts to measure the Quality of Service (QoS) and Quality of Experience (QoE) provided by telemedicine systems, thus making it impossible to understand their overall levels of user satisfaction in sub-Saharan African countries. Therefore, we conducted a qualitative and quantitative study, with experiments to measure QoS performance and the end-user QoE perception of telemedicine systems. Based on obtained results, we propose a mathematical formula to predict the QoE based on QoS measurement values, since a known relationship exists between QoS and QoE.

Alzheimer’s disease (AD) and Parkinson’s disease (PD) are devastating, frequent, and still incurable neurodegenerative diseases that manifest as cognitive and motor disorders. Epidemiological data support an inverse relationship between the amount of physical activity (PA) undertaken and the risk of developing these two diseases. Beyond this preventive role, exercise may also slow down their progression. Several mechanisms have been suggested for explaining the benefts of PA in the prevention of AD. Aerobic physical exercise (PE) activates the release of neurotrophic factors and promotes angiogenesis, thereby facilitating neurogenesis and synaptogenesis, which in turn improve memory and cognitive functions. Research has shown that the neuroprotective mechanisms induced by PE are linked to an increased production of superoxide dismutase, endothelial nitric oxide synthase, brain-derived neurotrophic factor, nerve growth factor, insulin-like growth factor, and vascular endothelial growth factor, and a reduction in the production of free radicals in brain areas such as the hippocampus, which is particularly involved in memory. Other mechanisms have also been reported in the prevention of PD. Exercise limits the alteration in dopaminergic neurons in the substantia nigra and contributes to optimal functioning of the basal ganglia involved in motor commands and control by adaptive mechanisms involving dopamine and glutamate neurotransmission. AD and PD are expansive throughout our ageing society, and so even a small impact of nonpharmacological interventions, such as PA and exercise, may have a major impact on public health.
