Beer, Japanese sake, red wine and shochu were adopted as the alcoholic subjects. The sensor outputs after 1 hour and 2 hours of drinking were adopted in the technique. The concentration grade was indicated using three metal-oxide odor sensors. It became obvious that the alcoholic component in the expiration could remain over 3 hours after drinking. Japanese elderly people mostly prefer beer and sake according to a questionnaire survey which was carried out for the aged, and the number of people was 68. The survey was carried out by a mail correspondence method. The number of males was 37 and the female number was 31. Many persons who received the questionnaire preferred beer and sake to whiskey and wine. In this study, the sensor-output characteristic as a function of passage of time after drinking sake was investigated and the suitable amount could be indicated by a developed technique. This means an amount of alcohol from which the subject feels refreshment of mind and body. In the questionnaire, it became obvious that 61% of aged men habitually drunk and 18% of females drunk. Women also preferred wine, plum liquor and shochu cocktails. This system was developed to survey the aged life style and identify whether they drunk moderately or not. And it can be also applicable to health monitoring for the elderly person.","PeriodicalId":370021,"journal":{"name":"WIT Transactions on Biomedicine and Health","volume":"16 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":"121247300","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}

Nowadays, one circumstance which might confuse the exposure reality is that the majority of solvents which are often used have a faint odour. Therefore, the conditions at offset printing in regard to solvent exposure may seem acceptable to workers. Fortunately, general ventilation and local exhaust systems have also become more common, and new printing machines, often with automatic cleaning, have entered the market. The health effects of volatile organic solvents are dependent on the chemicals involved but, normally, are associated with affecting the nervous system, the liver and also the kidneys. The purpose of this study was to document the conditions regarding exposure to volatile organic compounds in an offset printing unit and to permit identify task with higher exposure and with priority for preventive measures application. Exposure assessment was done before and after installation of general ventilation and local exhaust equipments and during printing and cleaning procedure. It was use portable VOCs measurement equipment with real-time measurements (MultiRAE, RAE Systems model) that allowed identify task with higher exposure. The need and appropriateness of ventilation introduction is measured by the significant statistically difference (p<.001) in the concentration results before","PeriodicalId":370021,"journal":{"name":"WIT Transactions on Biomedicine and Health","volume":"7 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":"117284482","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}

We sought to determine the effects of (1) lateral dominance, (2) body mass, (3) body height and (4) the direction of perturbation on the Lehr’s damping ratio for characterizing the balancing ability of 80 healthy young participants on an unstable oscillatory platform. Tests were performed while standing on both limbs and on one limb (dominant or nondominant), and the direction of oscillation was anterior-posterior and mediallateral. The healthy patients were divided into four groups based on body height and into five groups based on body mass. The average value of the Lehr’s damping ratio was significantly smaller for participants standing on their nondominant limb compared to their standing on both limbs or on the dominant limb. The largest difference of the Lehr’s damping ratio was 0.014 (2.5%) comparing the groups with different body mass, and it was 0.012 (2.1%) comparing the groups with different body height. A weak correlation was found between the Lehr’s damping ratio and body mass (r=0.14) and between the Lehr’s damping ratio and body height (r=0.19). There was a significant difference when comparing the Lehr’s damping ratio determined from oscillation in the anterior-posterior direction to the Lehr’s damping ratio determined from oscillation in the medial-lateral direction (p<0.008).

The approach used in this research integrates public health and anthropological methods to assess environmental and behavioral interactions that facilitate human exposure to bird flu. Four key elements of the H5N1 eco-biosociocultural model were identified: (1) the subsidized natural environment; (2) the built environment; (3) the socio-political and economic environment; and, (4) the cultural environment. Analysis of these elements resulted in development of an eco-biosociocultural disease model for H5N1 that addresses health disparities by incorporating the built and subsidized natural environments integrated with associated cultural beliefs, knowledge, and behaviors. Our results suggest that the disparate incidence and mortality pattern of H5N1 in Egypt is likely affected by increased exposure opportunities among women and children resulting from lack of knowledge, traditional daily activities, poultry practices, and child-rearing activities. Despite community based health education efforts, knowledge about poultry diseases and H5N1 transmission are not well understood among Egyptian women. In the absence of a perceived immediate bird flu threat, this research suggests that women tend to maintain traditional behaviors. The H5N1 epidemiologic footprint in Egypt differs from other countries, but the lessons learned provide a basis for health education action that may be transferable to other venues.","PeriodicalId":370021,"journal":{"name":"WIT Transactions on Biomedicine and Health","volume":"39 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":"121914123","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 is known that the fluid flow patterns downstream of an obstruction may be very complex and are three dimensional, including the formation of vortices, recirculating flow, flow separation and the onset of turbulence. The development of any such pattern of flow might be detrimental to the optimal performance of the flow system. In this work we have used the magnetic resonance imaging (MRI) technique to investigate flow dynamics downstream of an artificial heart valve. MRI is a naturally threedimensional, non-invasive technique that finds application in clinical, biomedical research and materials research. It has the capability to visualize the internal structure of materials and also to quantify mass transport properties. In this in vitro study, we have measured the turbulent diffusivity and velocity downstream of the valve in two configurations (fully opened and partially opened). Our particular implementation of the MRI measurement (known as SPRITE imaging) is unusually robust to fast turbulent flows and has been demonstrated effective at Reynolds numbers on the order 10 5 , much higher than possible with most conventional, clinical MRI techniques. The results showed a low turbulent diffusivity downstream of the fully opened valve configuration, while the turbulent diffusivity is higher downstream of the partially opened valve coupled with a high-velocity fluid jet and recirculating flow.
