Pressure ulcers are a major complication of spinal cord injury (SCI) and often develop despite frequent repositioning. This paper describes the development of a new hypothesis on the cause of pressure ulcers and its development into a novel, sensor-driven electronic device for their treatment and prevention. A prospective study carried out to determine the history of early-occurring pressure ulcers among patients with SCI admitted to the former Charity Hospital, New Orleans showed, as expected, that duration of immobilization prior to ward admission was a significant risk factor. However, the strongest risk factors were low systolic blood pressure and low partial pressure of oxygen at the time of admission to the emergency department. Poor circulatory function thus appeared to be a more important cause of ischemic injury and resultant ulcers than external pressure. These findings suggested that maintaining adequate tissue perfusion was the key to treatment and prevention. A new method was thus conceived of continuously monitoring tissue oxygenation at areas of high risk, combined with using therapeutic electrical stimulation to increase blood flow and raise tissue oxygenation when the level dropped below a set point. In subsequent research, tissue oxygenation at the sacrum was found to be lower in patients with SCI than in controls; furthermore, high voltage pulse galvanic stimulation (HVPGS) at 75 Hz applied to the back of patients with SCI lying supine increased transcutaneous oxygenation levels at the sacral area into the normal range within 10 minutes. A method has since been patented for automating and performing this task, called COMAS (Cutaneous Oxygen Monitoring and Stimulation) and discussions are underway to develop and manufacture the device
Politehnica University of Timisoara, Romania
Time : 10:15-11:00
Corneliu Bob has graduated at the University Politehnica of Timisoara,Romania in 1961 and PhD civil engineering in 1971 at the same University. In 1990 he became professor of R C structures and completed his PhD as scientific coordinator at the civil engineering from faculty in Timisoara. From 1996 till 2004 he was the head of the National Building Research Institute, Timisoara. He has also been very active in the Romanian Associations for Civil Engineering as National Association Engineering for Structural Analysis, Bucharest, Romanian Concrete Commission, Romanian Academy of Material Science. Since 1992, he became the member in the permanent committee as a chairman of the IABSE romanian group and member of the SED editorial board
The construction industry is one of the biggest polluter from the process of extracting the raw materials to the demolition process of the existing constructions. The building and construction industry uses 40% of the materials entering the global economy, consumes approximately 50% of the total energy supply and contributes with almost 50% to the total CO 2 emissions .This represent really a problem of the healthcare. Waste management encompasses the collection, transporting, storage, treatment, recovery and disposal of waste. There are only same of the countries highlighted waste management as one of the criteria of sustainability.
The aim of the present plenary speech is to underline the efficiency of the construction recycling. The main themes are: importance of construction recycling; experimental determinations; construction recycling properties. On the other hand, two important themes, with implication on efficient technology, are presented: a proper sustainability model and a quantitative appreciation of reinforcement corrosion.
The main advantages of the sustainability model are: cover the three dimensions of sustainability, includes only quantitative parameters (energy, materials, cost, manpower, waste, dust, noise, main strength etc.), flexibility of solutions and so on. The quantitative model of reinforcement corrosion gives a formula for average depth of carbonation or chloride penetration. These themes help specialists to choice proper materials as construction recycling
