“…However, a review of studies in Indoor Environmental Quality revealed that the relationship between indoor acoustic conditions and occupants' health seems not to have received adequate consideration (Frontczak and Wargocki, 2011). This is especially so in residences as well as other indoor environments outside the office space as evident in Aylward et al, (2005). The study remarked that regarding the relationships between aspects of the indoor environment and occupants' health, there has been considerable research into occupational (office or work) environments, while other indoor environments with significant potential health impacts have not enjoyed similar level of examination.…”

This study examined indoor sound pressure level in selected rooms within a students’ housing neighbourhood in Nigeria; assessed the self-reported physical health symptoms of the occupants; and analysed the relationships between the two. Sound pressure level was measured in each of the randomly selected 22 rooms at 15-minute intervals between 7hours and 19hours daily through a period of four weeks each during the peaks of both dry and wet seasons. The measurement was done with Data Loggers placed at work plane at the centre of the rooms. Purposive sampling was used to select all the occupants in the selected rooms as well as the two adjoining rooms to fill a questionnaire. This amounted to 696 respondents. The questionnaire, elicited information regarding what each respondent regarded as the most prominent source of noise, their gender, age and complexion, as well as their self-reported physical health status. This study found that a significant 79% of the respondents identified indoor noise sources as the prominent contributor to the acoustic condition in the rooms; that the mean measured sound pressure levels in each room layout ranged from 27.75 dB to 56.29 dB; and that the self-reported physical health symptoms with significantly high percentage of observation were cold, fatigue, and headache. Correlation analysis showed that there was an inverse relationship between the sound pressure level in the rooms and the frequency of observance of cold, fatigue, and headache among the occupants. However, the relationship is more significant during the wet season, and more pronounced in female occupants than in male.

“…To monitor daily activities of the elderly people, video cameras can be deployed in smart environments such as smart homes or smart hospitals to acquire time-series activity video clips as shown in Figure 1. Indeed, several studies support that personalized lifecare and healthcare services can decrease the mortality rate [3] especially for the elderly and disabled people in smart environments [4,5]. For instance, in the European countries, it is estimated that the proportion of older people is increasing while receiving personalized healthcare services instead of receiving institutional care or nursing home care.…”

Human activity recognition (HAR) is an emerging methodology essential for smart homes with practical applications such as personal lifecare and healthcare services for the elderly and disabled people. In this work, we present a novel HAR methodology utilizing the recognized body parts of human depth silhouettes and Hidden Markov Models (HMMs). We first create a database of synthetic depth silhouettes and their corresponding body parts labelled silhouettes of various human activities to train random forests (RFs). With the trained RFs, a set of 23 body parts are recognized from incoming depth silhouettes, yielding a set of centroids from the identified body parts. From the dynamics of these centroids, motion parameters are computed: a set of magnitude and directional angle features. Finally, the spatio-temporal dynamics of these motion features of various activities are used to train HMMs. We have performed HAR with the trained HMMs for six typical home activities and obtained the mean recognition rate of 97.16%. The presented HAR methodology should be useful for residents monitoring services at smart homes.

“…Com a chegada dos anos 90, as mudanças do estilo de vida da população urbana foram se consolidando e atualmente os habitantes das grandes cidades gastam cerca de 90% de seu tempo em ambientes internos e a qualidade do ar de ambientes internos, tornou-se um assunto de extrema importância mundial [9,16,17]. Desta forma, uma ênfase crescente vem sendo dada à poluição do ar em ambientes internos e os efeitos tóxicos à saúde causados pelos poluentes do ar tem sido alvo de interesse dos pesquisadores.…”

A Deus porque sem ELE nada somos.A Profa. Dra. Lilian Rothschild pela valiosa orientação, paciência e dedicação.Ao Superintendente do HU pela permissão concedida para a realização das amostragens!!! Aos meus pais Lydio (in Memorium) e Maria e meus irmãos, Paulo, Mario e Nádia, todo meu respeito, carinho e amor.Ao meu amado Tio Harold L. Palmer e minha Tia Helena Palmer todo o meu respeito, carinho e amor.Aos todos os meus Mestres, aqueles que durante a minha vida me conduziram para o caminho da verdade e da luz.Aos meus grandes amores, minha esposa Carol e minha filha Amanda.Ao meu sogro Celso e Marli, pela força, amizade, carinho e paciência, todo meu respeito, carinho e amor. A quantificação de 11 compostos carbonílicos (formaldeído, acetaldeído, acetona, acroleína, propionaldeído, crotonaldeído, butiraldeído, benzaldeído, isovaleraldeído, valeraldeído e 2,5-dimetilbenzaldeído) e a identificação de outros 43 compostos orgânicos voláteis (alcanos, alcenos, aromáticos, halogenados e nitrogenados) foram feitas em 9 ambientes diferentes de trabalho localizados em áreas internas do Hospital Universitário, USP, São Paulo.Dentre os compostos carbonílicos, os mais abundantes em ordem decrescente foram formaldeído, acetona, acetaldeído e acroleína. As maiores razões de mistura de formaldeído foram observadas nas salas de Macroscopia (169,9 e 90,2 ppbv) e Técnicas Histológicas (11,7 e 58,7 ppbv), em decorrência da atividade desenvolvida nos locais. Na sala de Macroscopia, os níveis de formaldeído encontrados foram acima do limite (100 ppbv) estabelecido por órgãos internacionais que controlam a qualidade do ar em ambientes internos não industriais.As razões de mistura entre o ambiente interno e o ambiente externo, razões I/E, permitiram indicar a predominância dos compostos carbonílicos nos ambientes internos. A acroleína foi encontrada na faixa de 6,4 a 9,3 ppbv nos ambientes internos estudados. Na área externa, entretanto, foram encontrados valores similares (6,4 e 6,8 ppbv) aos dos ambientes internos obtendo razões I/E próximas de 1. Os compostos podem ter sido emitidos por materiais de construção e acabamento, fumaça do tabaco, adesivos, via metabolismo microbiano e bacteriano ou podem ter sido transportados por correntes de ar do ambiente externo para o ambiente interno.Palavras-chave: compostos orgânicos voláteis (COV), compostos carbonílicos, ambientes internos, hospitais, ar, fontes de emissão. and Histological Techniques (11.7 and 58.7 ppbv), due to the routine activities of these places. At the Macroscopy room, the level of formaldehyde identified (100 ppbv) was above the international limits established to non-industrial internal places.The ratios of the mixture of indoor and outdoor places, I/O, indicate the biggest presence of carbonyl compounds in internal places. Acrolein has been identified (6.4 to 9.3 ppbv) at indoor places. At the external area, there where found similar values (6,4 to 6,8 ppbv), and the ratio I/O obtained is near to 1. The origin of these compounds is possibly construction materi...
