Organizational Factors and Office Workers’ Health After the World Trade Center Terrorist Attacks: Long-Term Physical Symptoms, Psychological Distress, and Work Productivity
No full textObjective: To assess if organizational factors are predictors of workers' health and productivity after the World Trade Center attacks.Methods: We conducted a survey of 750 workers and compared those who had direct exposures to the World Trade Center attacks (south of Canal Street workers; primary victims) with those less directly exposed (north of Canal Street workers; other victims and non-victims).Results: South of Canal Street workers reported headache more frequently than north of Canal Street workers did (P = 0.0202). Primary victims reported headache and cough more frequently than did other victims and non-victims (P = 0.0086 and 0.0043, respectively). Defensive organizational culture was an independent predictor of cough and job stress, and job stress was an independent predictor of on-the-job productivity losses.Conclusion: Organizational variables may modify health and productivity outcomes after a large-scale traumatic event in the workplace.This research was supported in part by the Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health (NIOSH) Grant 5 R21 OH007713-02, and the NIEHS sponsored UMDNJ Center for Environmental Exposures and Disease, Grant NIEHS P30ES005022.This is a non-final version of an article published in final form in Journal of Occupational and Environmental Medicine (50(2):112-25, 2008 Feb) a publication of Lippincott, Williams & Wilkins.

No full textThis study aims to assess the level of knowledge, attitude, and practice (KAP) toward Clostridium botulinum outbreak in home-canned bamboo shoots at Pakalung SubDistrict, Ban Luang District, Nan Province, Thailand. A cross-sectional approach was conducted to assess KAP using a structured questionnaire. A total of 280 people, randomly selected responded by face to face interview. The results indicated that the knowledge and attitude of the participants were moderate and neutral (57.9 % and 51.8 %, respectively). The prevalence of good practice level was 89.6 %. Furthermore, the knowledge was significantly associated with social-demographic characteristics (Chi-square, p<0.05) i.e. education level (p<0.001), occupation (p<0.029), monthly incomes (p<0.001). The attitude was associated with age group (p<0.001), education level (p<0.002), monthly incomes (p<0.001) and monthly incomes (p<0.001) are associated with practice level. The information gained would be utilized for health promotion and use of appropriate tools to increase more knowledge, and changing wrong beliefs concerning food habits and changing some people’s practices that might increase risk related to C. botulinum foodborne.Peer reviewed
Knowledge, Attitude, and Practice (KAP) of Using Personal Protective Equipment (PPE) for Chilli-Growing Farmers in Huarua Sub-district, Mueang District, Ubonrachathani Province, Thailand
No full textPesticide use in Thailand has increased significant, raising concerns about potentially adverse effects on human health and environment, in particular, as a number of pesticide products have been heavily used on chilli farms. The objectives of this study were: (1) to assess the knowledge, attitudes, and practices on using personal protective equipment (PPE) of chilli-growing farmers to protect themselves from pesticides, (2) to evaluate the knowledge, attitudes, and practices associated with pesticide use and exposure in the chilli-growing farmers, and (3) to provide recommendations and guidelines to reduce the exposure to pesticides among farmers in Huarua Sub-District, Mueang District, Ubonrachathani Province, Thailand. A standardized questionnaire was completed through face to face interviews with 330 chilli-growing farmers. The results showed that 53% of the participants were male and 39.6% and ages ranging between 31-40 years. 71.2 % had received primary school education and most of them applied pesticides by themselves. Almost 89.4% of respondents acknowledged that they ought to wear mask, boots, and cloth while spraying. Furthermore, 83.3% knew that pesticides can pass through their body in 3 ways; ingestion, dermal contact, and inhalation. In addition, 45.5% of respondents knew that spraying should be done in the windward direction and that they should use PPE. Many of the respondents checked their equipment before using them and wore clothing while spraying. Nevertheless, 77.2 % of chilli-growing farmers had low level of knowledge, 54.5 % of the farmers were not concerned about pesticide use or exposure, and 85.0 % of farmers demonstrated a fair level of actual usage. The associations between knowledge and attitude, knowledge and practice, and attitude and practice demonstrated statistical significance with low positive correlation (0.216, 0.285, and 0.305 respectively). The results suggested that government authorities and communities should be provided with the appropriate recommendations, strategies and guidelines to prevent adverse health effects regarding to pesticide exposure of farmers in this area.Peer reviewed
Assessing and Improving Bioterrorism Preparedness Among First Responders: A Pilot Study
No full textFollowing the September 11 terrorist attacks, the vulnerability of the United States became apparent. It also became evident that there was a need for respiratory protection. The purpose of this study was to determine the prior knowledge and perceptions of emergency medical technicians with respect to bioterrorism and to enhance their current knowledge to better prepare them for possible future events. The study was also designed to create a certified pool of trainers who would be capable of fit-testing all squad members with N-100 respirators. Representatives were recruited from each of the Hunterdon County, New Jersey, rescue squads. Participants attended a train-the-trainer session. Before the session and after, they were tested on knowledge and perceptions about relevant bioterrorism issues and were given an educational presentation on bioterrorism, threatening agents, respiratory health, and proper protection, along with being introduced to the fit-test steps for N-100 respirator masks. The response rate for the training was 94 percent. The authors measured and compared responses on the pre-test and the post-test with respect to knowledge, behaviors, and perceptions, and the results indicated a change following the training. The study thus provided evidence that the train-the-trainer program is an effective method of providing public health preparedness training to members of community organizations and agencies.Reprinted with permission from the Journal of Environmental Health, a publication of the National Environmental Health Association, www.neha.org.Supported by NIEHS Grants ES07148 and ES05022 and the Environmental and Occupational Health Sciences Institute.Peer reviewe

Effects of different irrigation in coffee genotypes conilon
No full textDue to the conditions of uneven distribution of rainfall in northern Espírito Santo, Brazil, cultivation of Conilon coffee (Coffeacanephora) has been done predominantly under irrigation with highly productive crops especially coffee production in Brazil. After the irrigation system implementation it is fundamental to the success of the project to implement a system of water management in irrigated crop, requiring a correct quantification of crop water consumption. The purpose of this study was to evaluate the response of different genetic materials (clones) of Conilon coffee to different irrigation. The study aimed quantification of water consumption, as well as to estimate the crop coefficient (Kc). The research was conducted in a farm called Córrego Grande in São Mateus, Espírito Santo state, Brazil in commercial cultivation of Conilon coffee in 3 x 0.8 m spacing, conventional drip irrigated, with a flow rate of 2 L h-1 and spaced 0.5 m. The experimental design was completely randomized in a subplot design, with six plots, five subplots and four replications. The plots were irrigation corresponding to 25%, 50%, 75%, 100%, 125%, 150% of evapotranspiration for a condition of drip irrigation. The subplots were Conilon called 02, 03, 18, 153 and bamburral. Each replication was consisted of 20 plants. Data were subjected to analysis of variance and the means of treatments (subplots) were compared by Tukey test at 5% probability. The averages of the treatments (plots), were subjected to polynomial regression analysis. Regarding the growth parameters the 150% evapotranspiration blade for located irrigation was superior to the other ones. As for the first crop productivity, the percentages of irrigation applied for the maximum productivity varied according to the evaluated clone from blade percentages of 94.7% (kc = 0.947) for clone 03, percentage to 123.9% of the blade EToLoc (kc = 1.239) for clone 02.Em razão das condições da distribuição irregular das chuvas na região norte do Espírito Santo, o cultivo de café Conilon (Coffea canephora) tem sido feito predominantemente sob irrigação, com lavouras altamente produtivas com destaque na produção cafeeira nacional. Após a implantação do sistema de irrigação torna-se fundamental ao sucesso do projeto a implementação do manejo de água do cultivo, requerendo uma correta quantificação do consumo hídrico da cultura. Diante isso, o trabalho teve como objetivo a avaliação da resposta de diferentes materiais genéticos (clones) de café Conilon a diferentes lâminas de irrigação, visando a quantificação do consumo hídrico, bem como a estimativa do coeficiente de cultura (Kc). A pesquisa foi conduzida na fazenda Córrego Grande, em São Mateus, em cultivo comercial de café Conilon, no espaçamento 3,0 x 0,8 m, irrigada por gotejamento convencional, com vazão do gotejador de 2 L h-1 e espaçados de 0,5 m entre si. O delineamento experimental foi inteiramente casualizado em parcela subdividida, com seis parcelas, cinco subparcelas e quatro repetições. As parcelas foram lâminas de irrigação correspondentes a 25%, 50%, 75%, 100%, 125%, 150% da evapotranspiração para condição de irrigação localizada. As subparcelas foram os genótipos de Conilon denominados 02, 03, 18, 153 e Bamburral. Cada repetição foi constituída de 20 plantas. Os dados foram submetidos à análise de variância e as médias dos tratamentos (subparcelas), comparadas pelo teste de Tukey a 5% de probabilidade. As médias dos tratamentos (parcelas), foram submetidos a análise regressão polinomial. Em todos os parâmetros vegetativos avaliados a porcentagem da lâmina aplicada de 150% da evapotranspiração para irrigação localizada foi superior às demais. Já para produtividade da primeira safra, as porcentagens das lâminas de irrigação aplicadas para a máxima produtividade variaram em função do clone avaliado, desde porcentagens de lâmina de 94,7% (kc = 0,947) para o clone 03, até porcentagem de lâmina de 123,9% da EToLoc (kc = 1,239) para o clone 02.Coordenação de Aperfeiçoamento de Pessoal de Nível Superio
Alternativas de manejo de água de irrigação em cultivos de Conilon.
No full textO cultivo do café Conilon no Norte Capixaba tem sido feito predominantemente sob irrigação, em razão das condições de distribuição irregular das chuvas. Após a implantação do sistema de irrigação, o manejo da água de irrigação torna-se muito importante do ponto de vista econômico e ambiental para o sucesso da irrigação do cafeeiro Conilon. Objetivou-se, neste trabalho, avaliar métodos de manejo de água em sistema de irrigação por microaspersão, empregado em cafeeiros Conilon adultos, na região de São Mateus (ES). Durante três safras (2008 a 2011) foram avaliados os efeitos do manejo de irrigação pelos métodos: balanço de água no sistema solo-planta-atmosfera, tensiometria e o sistema Irrigas, nas características produtivas de quatro clones do café Conilon. Os resultados obtidos indicaram que os manejos de irrigação pelo sistema Irrigas e o balanço hídrico possibilitaram as maiores produtividades, porém foram os que tiveram maior consumo de água e menor eficiência no uso da água de irrigação
Residents' perspectives on forest health issues and management practices in Mount Robson Provincial Park.
No full textBritish Columbia and in particular the Central Interior region have a long history of infestation by mountain pine beetle (Dendroctonus ponderosae). However, current levels of mountain pine beetles have reached epidemic proportions in part due to the changing weather conditions and forest management practices. This current epidemic has resulted in changed forest conditions that make the forests more susceptible to fire and renewed beetle attacks. The epidemic is of particular concern for parks and protected areas due to the long history of fire suppression and inactive management. In the Robson Valley, community members find themselves immersed in issues regarding forest health and mountain pine beetle management and the corresponding effects on amenity, property, and ecological values without sufficient information from reliable and trusted sources. The rich amenity values of the Robson Valley manifest themselves in active and vocal community members thus recent strategies for active management within Mount Robson Provincial Park have met with some resistance. Limited communication between BC Ministry of Environment and local residents regarding active management strategies has only served to amplify this opposition. A survey was conducted with residents of Valemount and McBride to explore their perceptions of forest health and management practices in the Robson Valley. Results show that residents overwhelmingly want to be involved in the planning process for active management in Mount Robson Provincial Park. Resident's agree with active management strategies for a variety of management rationale, however they do not agree with all forms of active management. Improved communication strategies could help agencies such as BC Ministry of Environment gain support for more controversial management actions.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b163702
