The paper presents a participatory design research framework as a primary method for structuring youth engagement, participation and contribution to the design, development and usability evaluation of three evidencebased e-tools for wellbeing, which include smart phone mobile apps as well as e-health websites. The three projects are part of a series of six e-tools part of Safe and Supportive program under Young and Well CRC. The participatory design method, developed by Zelenko (2012) for application in design of online health promoting technologies, was further piloted in partnership with Inspire USA for specific application within the CRC, deploying a combination of creative design workshops and speculative design activities in developing e-tool prototypes with young people. This paper presents the resulting participatory research framework as it was implemented across the e-tool projects to facilitate active youth participation in co-designing the e-tools and ensuring the final designs are relevant to young people and deliver health messages in engaging ways. The principles of Participatory Design (PD) that inform the new framework include a high degree of participant agency in creative decisionmaking and a commitment to the process of co-designing, with young people working alongside designers and developers. The paper will showcase how the PD framework was applied across three projects to increase young people’s contribution to final design outcome.

Objectives To address the scarcity of comprehensive, theory-based research in the Australian context, this study, using a theory of planned behaviour (TPB) framework, investigated the role of personal and social norms to identify the key predictors of adult Australians' sun-safe intentions and behaviour. Design The study used a prospective design with two waves of data collection, 1 week apart. Methods Participants were 816 adults (48.2% men) aged between 18 and 88 years recruited from urban, regional, and rural areas of Australia. At baseline, participants completed a questionnaire assessing the standard TPB predictors (attitude, subjective norm, and perceived behavioural control [PBC]), past behaviour, behavioural intention, and additional measures of group norm for the referent groups of friends and family, image norm, personal norm, personal choice/responsibility, and Australian identity. Seventy-one per cent of the participants (n = 577) reported on their sun-safe behaviour in the subsequent week. Results Via path modelling, past behaviour, attitude, group norm (friends), personal norm, and personal choice/responsibility emerged as independent predictors of intentions which, in turn, predicted sun-safe behaviour prospectively. Past behaviour, but not PBC, had direct effects on sun-safe behaviour. The model explained 61.6% and 43.9% of the variance in intention and behaviour, respectively. Conclusions This study provides support for the use of a comprehensive theoretical decision-making model to explain Australian adults' sun-safe intentions and behaviours and identifies viable targets for health-promoting messages in this high-risk context.

Antioxidants in acute physical exercise and exercise training remain a hot topic in sport nutrition, exercise physiology and biology, in general (Jackson, 2008; Margaritis and Rousseau, 2008; Gomez-Cabrera et al., 2012; Nikolaidis et al., 2012). During the past few decades, antioxidants have received attention predominantly as a nutritional strategy for preventing or minimising detrimental effects of reactive oxygen and nitrogen species (RONS), which are generated during and after strenuous exercise (Jackson, 2008, 2009; Powers and Jackson, 2008). Antioxidant supplementation has become a common practice among athletes as a means to (theoretically) reduce oxidative stress, promote recovery and enhance performance (Peternelj and Coombes, 2011). However, until now, requirements of antioxidant micronutrients and antioxidant compounds for athletes training for and competing in different sport events, including marathon running, triathlon races or team sport events involving repeated sprinting, have not been determined sufficiently (Williams et al., 2006; Margaritis and Rousseau, 2008). Crucially, evidence has been emerging that higher dosages of antioxidants may not necessarily be beneficial in this context, but can also elicit detrimental effects by interfering with performance-enhancing (Gomez-Cabrera et al., 2008) and health-promoting training adaptations (Ristow et al., 2009). As originally postulated in a pioneering study on exercise-induced production of RONS by Davies et al. (1982) in the early 1980s, evidence has been increasing in recent years that RONS are not only damaging agents, but also act as signalling molecules for regulating muscle function (Reid, 2001; Jackson, 2008) and for initiating adaptive responses to exercise (Jackson, 2009; Powers et al., 2010). The recognition that antioxidants could, vice versa, interact with the signalling pathways underlying the responses to acute (and repeated) bouts of exercise has contributed important novel aspects to the continued discussion on antioxidant requirements for athletes. In view of the recent advances in this field, it is the aim of this report to examine the current knowledge of antioxidants, in particular of vitamins C and E, in the basic nutrition of athletes. While overviews on related topics including basic mechanisms of exercise-induced oxidative stress, redox biology, antioxidant defence systems and a summary of studies on antioxidant supplementation during exercise training are provided, this does not mean that this report is comprehensive. Several issues of the expanding and multidisciplinary field of antioxidants and exercise are covered elsewhere in this book and/or in the literature. Exemplarily, the reader is referred to reviews on oxidative stress (Konig et al., 2001; Vollaard et al., 2005; Knez et al., 2006; Powers and Jackson, 2008; Nikolaidis et al., 2012), redox-sensitive signalling and muscle function (Reid, 2001; Vollaard et al., 2005; Jackson, 2008; Ji, 2008; Powers and Jackson, 2008; Powers et al., 2010; Radak et al., 2013) and antioxidant supplementation (Williams et al., 2006; Peake et al., 2007; Peternelj and Coombes, 2011) in the context with exercise. Within the scope of the report, we rather aim to address the question regarding requirements of antioxidants, specifically vitamins C and E, during exercise training, draw conclusions and provide practical implications from the recent research.

Previous empirical research has shown that positive, i.e. salutogenic, psychological resources and social support, have health-promoting effects in stressful life situations. In the present study the associations between sense of coherence (SOC), dispositional optimism, partner support, psychological distress, and quality of life among cancer patients and their partners were examined. The data was collected from Helsinki University Central Hospital in 1997 2000 by self-report questionnaires approximately 2, 8, and 14 months post diagnosis. Participants in studies I-IV were 155, 123, 153, and 147 cancer patients and their partners, respectively. The sample of the present study consisted of physically relatively well-functioning patients, whose overall psychological wellbeing was generally good as compared to the healthy population. Partners in this study, however, reacted more strongly to their partners illness and treatment. The partners displayed e.g. higher levels of anxiety and depression than the patients. The results of this study indicated that cancer patients and their partners with strong SOC and who are optimistic report fewer symptoms of distress. Moreover, patients who display an optimistic attitude to life, who receive support from their partner, and who control how they express anger have a better quality of life. The findings also confirmed that the role of the partner is significant in coping with cancer. The symptoms of depression and anxiety in patients and partners were associated, and the partner s optimism seemed to protect also the patient from elevated levels of anxiety. The role of the partner was also highlighted in the couples anger-expression styles. The patients and partners tendency to inhibit anger was associated with decreased partner support and worse patient quality of life. Finally, in the present study we found substantial gender differences. For the patients, partner support was more significant for the women than for the men. Furthermore, for the female patients, the husband s tendency to openly express anger (anger-out) had a negative impact on their psychological quality of life, whereas the wives high anger-out seemed to predict good psychological quality of life in the men. Also, in this study the female partners reported higher levels of anxiety and depression as compared to the male partners. The results of the present study extend the previous literature on positive psychological resources and psychological wellbeing among cancer couples. Furthermore, these findings support the theory on SOC and optimism as health-promoting factors. However, the construct of SOC seems to include other important elements besides optimism. The findings of this study are applicable in designing new rehabilitation programmes for cancer patients and their partners.

Aims: The older the youngsters are, the more important role hobbies and leisure time activities have in their life. That is why various activities organized by the non-profit organizations have an important role concerning the development of food habits of youngsters. This study has three main themes. The themes and their respective study questions are: 1. The youngsters' conceptions on healthy eating and food choice: What kind of food do youngsters consider as healthy? How do they see their own eating habits from this point of view? 2. The youngsters and the significance of everyday food-related information: How do the youngsters perceive the role of different actors and these actors' role regarding their own food habits and food choice? 3. The possibilities of the organizations that work with youngsters to improve their food habits: What kind of role do the non-profit organizations have on the youngsters' food habits and healthy food choice? Methods: This study comprises of two types of data. First, a quantitative internet-based survey (N=582) was used to collect data on the 9th graders conceptions and understandings. The data was analyzed with the SPSS-program. Means, cross-tabulations, Pearson´s correlations and t-test were calculated from the data. The qualitative data was collected using interviews. The respondents were 12 experts from non-profit organizations. The interviews were analyzed with the qualitative content analysis. Results and conclusions: The non-profit organizations studied have good possibilities to communicate with youngsters through their hobbies. As part of their activities these organizations are able to influence on health-promoting lifestyle and food habits of youngsters. In order to reach more youngsters, these organizations should actively act e.g. in virtual societies of youngsters. Youngsters will participate when activities are voluntary and exhilarating. From the point of food habits doing, learning and identifying are the most important factors to engage the young. Also the models of peers and adults are important. Non-profit organizations should offer youngsters activities but these organizations should also influence on society.

The rapid increase in allergic diseases in developed, high-income countries during recent decades is attributed to several changes in the environment such as urbanization and improved hygiene. This relative lack of microbial stimulation is connected to a delay in maturation of the infantile immune system and seems to predispose especially genetically prone infants to allergic diseases. Probiotics, which are live ingestible health-promoting microbes, may compensate for the lack of microbial stimulation of the developing gut immune system and may thus be beneficial in prevention of allergies. Prebiotics, which are indigestible nutrients by us, promote the growth and activity of a number of bacterial strains considered beneficial for the gut. In a large cohort of 1 223 infants at hereditary risk for allergies we studied in a double-blind placebo-controlled manner whether probiotics administered in early life prevent allergic diseases from developing. We also evaluated their safety and their effects on common childhood infections, vaccine antibody responses, and intestinal immune markers. Pregnant mothers used a mixture of four probiotic bacteria or a placebo, from their 36th week of gestation. Their infants received the same probiotics plus prebiotic galacto-oligosaccharides for 6 months. The 2-year follow-up consisted of clinical examinations and allergy tests, fecal and blood sampling, and regular questionnaires. Among the 925 infants participating in the 2-year follow-up the cumulative incidence of any allergic disease (food allergy, eczema, asthma, rhinitis) was comparable in the probiotic (32%) and the placebo (35%) group. However, eczema, which was the most common manifestation (88%) of all allergic diseases, occurred less frequently in the probiotic (26%) than in the placebo group (32%). The preventive effect was more pronounced against atopic (IgE-associated) eczema which, of all atopic diseases, accounted for 92%. The relative risk reduction of eczema was 26% and of atopic eczema 34%. To prevent one case of eczema, the number of mother-infant pairs needed to treat was 16. Probiotic treatment was safe without any undesirable outcome for neonatal morbidity, feeding-related behavior, serious adverse events, growth, or for vaccine-induced antibody responses. Fewer infants in the probiotic than in the placebo group received antibiotics during their first 6 months of life and thereafter to age 2 years suffered from fewer respiratory tract infections. As a novel finding, we discovered that high fecal immunoglobulin A (IgA) concentrations at age 6 months associated with reduced risk for atopic (IgE-associated) diseases by age 2 years. In conclusion, although feeding probiotics to high-risk newborn infants showed no preventive effect on the cumulative incidence of any allergic diseases by age 2, they apparently prevented eczema. This probiotic effect was more pronounced among IgE-sensitized infants. The treatment was safe and seemed to stimulate maturation of the immune system as indicated by increased resistance to respiratory infections and improved vaccine antibody responses.

Lactobacillus rhamnosus GG is a probiotic bacterium that is known worldwide. Since its discovery in 1985, the health effects and biology of this health-promoting strain have been researched at an increasing rate. However, knowledge of the molecular biology responsible for these health effects is limited, even though research in this area has continued to grow since the publication of the whole genome sequence of L. rhamnosus GG in 2009. In this thesis, the molecular biology of L. rhamnosus GG was explored by mapping the changes in protein levels in response to diverse stress factors and environmental conditions. The proteomics data were supplemented with transcriptome level mapping of gene expression. The harsh conditions of the gastro-intestinal tract, which involve acidic conditions and detergent-like bile acids, are a notable challenge to the survival of probiotic bacteria. To simulate these conditions, L. rhamnosus GG was exposed to a sudden bile stress, and several stress response mechanisms were revealed, among others various changes in the cell envelope properties. L. rhamnosus GG also responded in various ways to mild acid stress, which probiotic bacteria may face in dairy fermentations and product formulations. The acid stress response of L. rhamnosus GG included changes in central metabolism and specific responses related to the control of intracellular pH. Altogether, L. rhamnosus GG was shown to possess a large repertoire of mechanisms for responding to stress conditions, which is a beneficial character of a probiotic organism. Adaptation to different growth conditions was studied by comparing the proteome level responses of L. rhamnosus GG to divergent growth media and to different phases of growth. Comparing different growth phases revealed that the metabolism of L. rhamnosus GG is modified markedly during shift from the exponential to the stationary phase of growth. These changes were seen both at proteome and transcriptome levels and in various different cellular functions. When the growth of L. rhamnosus GG in a rich laboratory medium and in an industrial whey-based medium was compared, various differences in metabolism and in factors affecting the cell surface properties could be seen. These results led us to recommend that the industrial-type media should be used in laboratory studies of L. rhamnosus GG and other probiotic bacteria to achieve a similar physiological state for the bacteria as that found in industrial products, which would thus yield more relevant information about the bacteria. In addition, an interesting phenomenon of protein phosphorylation was observed in L. rhamnosus GG. Phosphorylation of several proteins of L. rhamnosus GG was detected, and there were hints that the degree of phosphorylation may be dependent on the growth pH.

Pesquisa de natureza descritiva e abordagem quantitativa de dados sobre a Aplicabilidade da Norma Regulamentadora-32 (NR 32) do Ministério do Trabalho e Emprego (MTE), visando mobilizar os trabalhadores de enfermagem para reduzir a exposição aos riscos inerentes do trabalho em estabelecimentos de saúde. Problema de pesquisa: Quais os fatores que interferem na implantação da Norma Regulamentadora-32 nas enfermarias de um Hospital Público Estadual do Rio de Janeiro, na visão dos trabalhadores de enfermagem? Teve como objetivo geral analisar os fatores que interferem na aplicabilidade da NR 32 pela enfermagem, em um hospital público do Rio de Janeiro. A população foi composta de 138 trabalhadores de enfermagem das enfermarias de clínica médica, cirúrgica e ortopédica. Utilizou-se para a coleta de dados um questionário estruturado com perguntas fechadas. Os dados foram coletados no período de 28 de janeiro a 14 de fevereiro de 2009, e analisados através do Programa Statical Package for the Social Sciences (SPSS) versão 13 for Windows e Microsoft Office Excel 2003. Os resultados apontaram que os trabalhadores de enfermagem desse hospital estão, em sua maioria, na faixa etária de 30-49 anos, com pelo menos 1 ano de atuação no mesmo setor e formaram-se há 15 anos ou mais, além disso, 68,1% são estatutários. Constatou-se que há recomendações da NR-32 e precauções-padrão não são seguidas pelos participantes da pesquisa. Os fatores que interferem no cumprimento da atual legislação vão desde o desconhecimento dos riscos ocupacionais e comportamento dos trabalhadores, até a falta de uma ação efetiva de Educação Continuada e da Comissão de Controle de Infecção Hospitalar (CCIH). Destacaram-se, entre outros, o uso de adornos (51,8%); calçado aberto (48,9%); alimentação no posto de trabalho (46,3%); uso da pia para outras finalidades (44,9%), reencape ou desconexão manual de agulhas (36,4%); sair do local de trabalho com uniforme ou Equipamento de Proteção Individual - EPI (21%); limite de recipiente de descarte de perfurocortantes não respeitado (11,8%), falta de uso de EPI quando auxilia no exame com Raios-X (32,6%) e na manipulação de quimioterápicos (7,8%). A instituição não fornece uniformes nem calçados. Outros fatores institucionais foram a falta de equipamentos, a falta de um política de prevenção e promoção da saúde, inexistência de serviço de saúde ocupacional e instalações físicas inadequadas. Tal descumprimento expõe, de forma excessiva, os trabalhadores de enfermagem aos mais variados fatores de riscos ocupacionais, podendo refletir na sua saúde e no processo de trabalho. Recomenda-se um trabalho efetivo e integrado dos Programas de Educação Continuada e CCIH para esclarecimento dos trabalhadores de enfermagem, e implantação do Serviço de Saúde do Trabalhador. Sugere-se aos gestores expandirem este estudo para os demais setores das unidades hospitalares e outras instituições públicas de saúde para o conhecimento da situação de trabalho, bem como a criação de espaços de discussão para a busca de soluções dos problemas com a participação dos trabalhadores.

Shén神 é uma categoria chinesa de sentidos múltiplos e abrangentes, presente na filosofia e na medicina. Direcionaria o processo de surgimento de todas as coisas no universo, como uma força configuradora. Na pessoa, atuaria sobre todos os estágios de desenvolvimento corporal e pessoal, do nascimento até a morte, caracterizando-a como pessoa única no universo. Teve seus sentidos reduzidos pela Medicina Chinesa Contemporânea, hegemônica na China e instituída após a Revolução comunista. Costuma ser traduzida como Espírito ou Mente no ocidente e é indissociável do corpo físico. Está presente em todas as dimensões da Racionalidade Médica Chinesa, observando-se na literatura convencional, grande abrangência de sentidos quando tratada pela dimensão cosmológica, porém costuma ser reduzida aos sentidos de mente, segundo definições ocidentais, quando tratada pelas dimensões de ordem prática: diagnose e terapêutica. O desafio desta tese foi elaborar uma síntese entre os sentidos cosmológicos e as dimensões práticas. Para isso, procedeu a uma pesquisa teórico conceitual, a partir de leituras e interpretações ocidentais de textos clássicos chineses, elaboradas por autores com critério filológico apurado. Observou-se que os sentidos de Shén神 se fazem presentes em ressonância recíproca com diversas outras categorias da Doutrina Médica Chinesa, como Qì氣, Xuè血, Jīng精, Qìng情, Emoções, Zàng-Fǔ贓腑, Órgãos e Vísceras, entre outras. Cada uma delas com atribuições específicas, que, porém, se reorganizariam em ressonância com as outras. Assim, ao proceder a diagnose e instituir uma terapêutica direcionada a cada uma dessas categorias, o terapeuta estaria interferindo diretamente sobre Shén神 e vice versa. Shén神 poderia assumir sentidos diversos, numa visão de totalidade. A partir daí, percebeu-se a necessidade de estudar essas categorias em ressonância com Shén神, além da própria diagnose e da terapêutica, à luz das premissas do Pensamento Chinês. Categorias como processo, totalidade, potencial ou eficácia ajudaram a apreender, não só os amplos sentidos de Shén神, e suas ressonâncias, mas também as peculiaridades do ato de diagnosticar e tratar na Racionalidade Médica Chinesa. Foi, então, elaborada uma visão da Diagnose e da Terapêutica capaz de contemplar Shén神 e suas ressonâncias, que se espera poder utilizar nos serviços de saúde, contribuindo para estratégias de promoção da saúde, estreitamento de vínculos terapeuta-paciente e maior eficácia terapêutica na prática da Racionalidade Médica Chinesa.

Em 1988, a Assembleia Constituinte, no rastro do processo de redemocratização do país, finalmente apontava para a transformação das políticas sociais no Brasil, cujo resultado foi lavrado na Carta Magna. A partir desse momento, os brasileiros obtiveram o direito de cidadania como estatuto fundamental de nacionalidade, e o direito à saúde como princípio de cidadania. Neste sentido, o setor saúde foi pioneiro nas práticas das políticas sociais no Brasil. A adoção de seus princípios doutrinários e operacionais por lei destacando-se aqui a integralidade significou a afirmação do direito à saúde como caminho de supressão da estrutura fragmentada de organização dos serviços de saúde no Brasil. Integralidade emerge como eixo de organização da defesa do direito à saúde, a partir das propostas de mudanças das práticas no cotidiano dos serviços. O objetivo deste estudo foi analisar as relações existentes entre os usuários do Sistema Único de Saúde (SUS), a partir dos Conselhos de Saúde, e o Ministério Público (MP) desenvolvida no município de Porto Alegre, no estado do Rio Grande do Sul, no que concerne à utilização de dispositivos institucionais e jurídico legais no cumprimento do direito à saúde. O foco deste estudo esteve voltado para a experiência desenvolvida entre os anos de 2000 e 2004, no município de Porto Alegre. Historicamente, os Conselhos de Saúde naquele estado têm desempenhado papel de destaque na formulação e acompanhamento das políticas públicas de saúde. O avanço desses conselhos permitiu-lhes desenvolver novas estratégias na luta pela garantia do direito à saúde, e o MP vem sendo importante parceiro nessa disputa. Nesse cenário, pudemos observar a utilização, cada vez mais freqüente, do princípio da integralidade como recurso legal na discussão encaminhada pelos usuários junto ao MP, no intuito de garantir o direito à saúde. O princípio da integralidade tem sido utilizado como proposta de transformação da própria lógica da gestão de oferta de serviços. O MP tem propiciado uma interlocução cada vez maior entre a gestão dos serviços e os conselhos de saúde, a fim de encontrar melhores saídas para os principais problemas de saúde do município. Esse espaço de diálogo criado pelo MP constitui avanço substancial na compreensão das formas de solução de conflitos, fundando um novo campo de práticas de aprimoramento do Estado democrático. A atuação conjunta do MP com os Conselhos de Saúde tem levado a instituir novas formas e mecanismos de negociação e pactuação entre as diferentes esferas dos poderes públicos e sua relação com a sociedade, no que diz respeito à institucionalização de uma gramática civil de direito à saúde.

Esta dissertação analisou as Empresas Promotoras de Salud (EPS), seguradoras de saúde introduzidas no sistema de saúde colombiano através da reforma sanitária instaurada com a Lei n 100/1993, desde uma perspectiva de economia política crítica, através do método de análise documental. A maioria delas são empresas privadas com finalidade lucrativa que conformaram rapidamente um oligopólio que reproduziu problemas dos modelos de Managed Care e Managed Competition já conhecidos internacionalmente. Esta dissertação analisou as relações entre os processos de financeirização do sistema capitalista e o processo de ajuste estrutural na Colômbia, com a reforma sanitária e a dinâmica financeira das EPS. Também foi analisada a introdução de mecanismos próprios do processo de financeirização na gestão financeira das EPS, como: a alavancagem; a reprodução ampliada de capital através da dívida pública; e os investimentos em ativos securitizados. Dado que o sistema de saúde atual se caracteriza por altos níveis de inequidade e injustiça, as consequências da finalidade lucrativa neste, com suas expressões concretas de sofrimento e morte na população, foram preocupações transversais deste trabalho. Os resultados desta dissertação demonstraram a concentração oligopólica do mercado de seguros privados de saúde, cujas empresas se organizaram como um cartel, dificultando o acesso aos serviços de saúde para seus segurados, o que contribuiu para a piora de indicadores de saúde da população. Quando a mobilização social obrigou a aumentar o controle sobre as EPS, estas começaram a sair do mercado declarando-se em falência, ou entrando subitamente em balanços financeiros negativos.

A presente dissertação busca realizar a descrição e sistematização de categorias analíticas que contribuam com análises sobre as relações econômicas, políticas e sociais que sustentam a forma como se constituem historicamente no Brasil o Estado e as políticas públicas na área social, com especial atenção para a área de saúde. Tal objetivo se constituiu na observação das novas estratégias utilizadas pelo Estado para a execução de ações na área de saúde, como os projetos sociais. Tomamos o método do materialismo histórico dialético como referencial teórico, com especial atenção às categorias da filosofia da práxis práxis, totalidade, historicidade e contradição e a teoria marxista sobre a formação do Estado capitalista e suas transformações históricas, com ênfase na teoria sobre o Estado ampliado e o papel da sociedade civil na disputa entre as classes pela hegemonia. No segundo capítulo, abordamos a organização contemporânea do Estado brasileiro, buscando discutir escolhas políticas e econômicas, suas implicações para a organização dos trabalhadores e para a correlação de forças na disputa entre as classes. Foi feito breve levantamento histórico sobre os modelos de desenvolvimento econômico e social nas sociedades contemporâneas, com atenção à consolidação do ideário neoliberal, sua conceituação, as adequações que sofreu a partir do final dos anos 1990 e sua relação com a ideologia desenvolvimentista. Dedicamos o terceiro capítulo ao conceito de capital social, como maneira de compreender a atual forma de desenvolvimento das políticas públicas e em especial as políticas de saúde. A partir deste conceito buscou-se compreender a relação entre Estado e sociedade civil na atualidade e como este influencia as transformações por que passaram o Estado e as políticas sociais. Abordou-se o desenvolvimento das políticas públicas da área social no Estado brasileiro até sua conformação no neoliberalismo; as concepções de saúde em disputa na sociedade brasileira, focando no conceito ampliado de saúde e no de determinação social da saúde; e de que forma estes conceitos são impactados pelas mudanças no contexto do neoliberalismo. Finalmente, foi possível observar como as orientações neoliberais alteraram significativamente a forma de organização e atuação do Estado, a concepção e aplicação de políticas públicas, bem como as políticas de saúde e seu ideário. Mudanças que fizeram pender a atuação do Estado ainda mais a favor dos interesses do capital.

Over the past 50 years, economic and technological developments have dramatically increased the human contribution to ambient noise in the ocean. The dominant frequencies of most human-made noise in the ocean is in the low-frequency range (defined as sound energy below 1000Hz), and low-frequency sound (LFS) may travel great distances in the ocean due to the unique propagation characteristics of the deep ocean (Munk et al. 1989). For example, in the Northern Hemisphere oceans low-frequency ambient noise levels have increased by as much as 10 dB during the period from 1950 to 1975 (Urick 1986; review by NRC 1994). Shipping is the overwhelmingly dominant source of low-frequency manmade noise in the ocean, but other sources of manmade LFS including sounds from oil and gas industrial development and production activities (seismic exploration, construction work, drilling, production platforms), and scientific research (e.g., acoustic tomography and thermography, underwater communication). The SURTASS LFA system is an additional source of human-produced LFS in the ocean, contributing sound energy in the 100-500 Hz band. When considering a document that addresses the potential effects of a low-frequency sound source on the marine environment, it is important to focus upon those species that are the most likely to be affected. Important criteria are: 1) the physics of sound as it relates to biological organisms; 2) the nature of the exposure (i.e. duration, frequency, and intensity); and 3) the geographic region in which the sound source will be operated (which, when considered with the distribution of the organisms will determine which species will be exposed). The goal in this section of the LFA/EIS is to examine the status, distribution, abundance, reproduction, foraging behavior, vocal behavior, and known impacts of human activity of those species may be impacted by LFA operations. To focus our efforts, we have examined species that may be physically affected and are found in the region where the LFA source will be operated. The large-scale geographic location of species in relation to the sound source can be determined from the distribution of each species. However, the physical ability for the organism to be impacted depends upon the nature of the sound source (i.e. explosive, impulsive, or non-impulsive); and the acoustic properties of the medium (i.e. seawater) and the organism. Non-impulsive sound is comprised of the movement of particles in a medium. Motion is imparted by a vibrating object (diaphragm of a speaker, vocal chords, etc.). Due to the proximity of the particles in the medium, this motion is transmitted from particle to particle in waves away from the sound source. Because the particle motion is along the same axis as the propagating wave, the waves are longitudinal. Particles move away from then back towards the vibrating source, creating areas of compression (high pressure) and areas of rarefaction (low pressure). As the motion is transferred from one particle to the next, the sound propagates away from the sound source. Wavelength is the distance from one pressure peak to the next. Frequency is the number of waves passing per unit time (Hz). Sound velocity (not to be confused with particle velocity) is the impedance is loosely equivalent to the resistance of a medium to the passage of sound waves (technically it is the ratio of acoustic pressure to particle velocity). A high impedance means that acoustic particle velocity is small for a given pressure (low impedance the opposite). When a sound strikes a boundary between media of different impedances, both reflection and refraction, and a transfer of energy can occur. The intensity of the reflection is a function of the intensity of the sound wave and the impedances of the two media. Two key factors in determining the potential for damage due to a sound source are the intensity of the sound wave and the impedance difference between the two media (impedance mis-match). The bodies of the vast majority of organisms in the ocean (particularly phytoplankton and zooplankton) have similar sound impedence values to that of seawater. As a result, the potential for sound damage is low; organisms are effectively transparent to the sound – it passes through them without transferring damage-causing energy. Due to the considerations above, we have undertaken a detailed analysis of species which met the following criteria: 1) Is the species capable of being physically affected by LFS? Are acoustic impedence mis-matches large enough to enable LFS to have a physical affect or allow the species to sense LFS? 2) Does the proposed SURTASS LFA geographical sphere of acoustic influence overlap the distribution of the species? Species that did not meet the above criteria were excluded from consideration. For example, phytoplankton and zooplankton species lack acoustic impedance mis-matches at low frequencies to expect them to be physically affected SURTASS LFA. Vertebrates are the organisms that fit these criteria and we have accordingly focused our analysis of the affected environment on these vertebrate groups in the world’s oceans: fishes, reptiles, seabirds, pinnipeds, cetaceans, pinnipeds, mustelids, sirenians (Table 1).
