What have we learnt from natural disasters in the past, and what can we do differently in the management of critical disasters to minimise their impact on life, property and the environment? From a realistic and practical perspective, this paper will challenge conference attendees to consider the relationship between historical events and generational complacency, a learning from history, in measures to manage disasters, from devastating floods (which regularly flood the major Australian state of Queensland and city of Brisbane), to bushfires in 2009 which killed almost 200 hundred people. Australia has a unique history of natural disasters, ranging from extremes in high temperature, to floods and cyclones. The impacts of these are highly destructive, and Australia, like some countries, has partly learnt from the past, and has developed extensive capability and strategic approaches for pre-empting and managing such events, lessons which have world wide application and benefit. Techniques for pre-planning as well as dealing with the aftermath of a disaster are critical in ensuring that the confidence of the public is restored and/or maintained to ensure the effective “normalisation” of communities post the disaster. A simple risk management philosophy will be proposed to define the 5 lessons to manage such disasters, which all too often are a victim of generational complacency resulting in ineffective emergency management. The paper will provide a summary of mistakes from the past, Australia’s current initiatives and techniques in addressing emergency needs, including prevention, communication, response and recovery.

Thermal comfort depends on several factors such as temperature conditions of the operating room, insulation of protective clothing, stress, rate of metabolism and safety mechanisms in the body to keep core temperature stable. The modification of any of these elements triggers defense mechanisms which in extreme cases may lead to serious disturbances in the body. The maintenance of recommended standards (ISO 7330) concerning thermal conditions in operating rooms ensures the highest possible physical capabilities of the personnel while providing maximum safety for the patients. The purpose of the present work is to report the results obtained during an experimental campaign carried out at the Umberto I Hospital in Enna in order to improve efficiency of HVAC installations to secure thermal comfort in the operating rooms.","PeriodicalId":370021,"journal":{"name":"WIT Transactions on Biomedicine and Health","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122280266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Substantial scientific evidence supports that inhalation of emissions from diesel exhaust particulates is associated with a range of adverse health effects. Measurements have shown that underground miners can be exposed to over 100 times the typical environmental concentrations of diesel particulate matter (DPM) and over 10 times the concentration measured in other work environments where diesel engines are common. This paper reports personal and environmental exposures to DPM in an underground mine in Western Australia. The findings demonstrated that the DPM concentration exceeded the provisional 8-hour time weighted average exposure standard of 0.1 mg/m 3 for most of the assessed locations. The elemental analysis indicated high concentrations of silica and iron in DPM which could be potentially associated with some adverse health effects including respiratory illnesses and irritating effects. Thermal comfort underground was also assessed and the results showed non compliance with the standards of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).","PeriodicalId":370021,"journal":{"name":"WIT Transactions on Biomedicine and Health","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132938986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One area of aerosol science that is currently of much interest, and is the focus of this article, is the formation of particles by combustion. Our major concern is with so-called “nanoparticles” (diameter less than 50 nm), which can be formed, for example, from diesel engine and can be associated with health effects. One of the objectives of this pilot study was to characterize the NanoMoudi Model 125B which a second generation micro-orifice uniform deposit impactor. This new equipment is designed for sampling atmospheric aerosols and also for diesel emission monitoring and analysis. As part of this study the concentrations of particles with different size including PM10, PM2.5, and PM1.0 were also measured at different locations away from busy road within Perth metropolitan area using TSI DustTrakTM 8520 Aerosol Particulate Monitor and TSI P-Trak 8525 Ultrafine Particle Counter. The results of the study showed that the NanoMoudi could be used to successfully collect and analyze fine and ultrafine particles including diesel particulates. Further to this, people who lived closer to busy roads were more likely to be exposed to higher concentrations of ultrafine particles which could be associated with adverse health effects.","PeriodicalId":370021,"journal":{"name":"WIT Transactions on Biomedicine and Health","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128072952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It represents a major health problem for most modern societies. The reasons for this increase might be the association of pollen with air pollutants. Hyper-reactivity tests are being conducted on mice and rats for allergic immune response. However, such tests cannot evaluate the deposition of pollen to the respiratory tract, because they force the animals to be immunized to pollen allergen mixed with air pollutants separately. The purpose of this study is to investigate how air pollutants deposit onto airborne Cryptomeria japonica pollen grains during the pollen-flying season between urban and mountainous areas, and to aid further bioreactivity and hypersensitive research. Suspended particulate matter (SPM), Cryptomeria japonica perigonium and pollen grains were collected to identify the deposition of air pollutants in an urban area, Saitama City, and in a mountainous area, Okuchichibu, during the pollen flying seasons. Ionic and metallic components of SPM and perigonium and pollen grains were analyzed. We found that crustal components (Al, Fe and Ti) tended to deposit on pollen perigonium. The amount of ionic components of particles (NO3, SO4 and NH4) and gaseous pollutants (NO2, SO2 and NH3) deposited on the perigonium and pollen grains were higher in the urban than in the mountainous areas, the results of which was proven by determination of gaseous Environmental Health Risk V 77 © 2009 WIT Press WIT Transactions on Biomedicine and Health, Vol 14, www.witpress.com, ISSN 1743-3525 (on-line) doi:10.2495/EHR090081 pollutants exposed to Cryptomeria japonica pollen.
