The efficacy of surveys in detecting Canada Lynx (Lynx canadensis) can vary considerably by geographic area. We conducted surveys using digital passive infrared trail video-cameras from January to April 2013, during the breeding season of the Canada Lynx, in the John Prince Research Forest in central British Columbia. We used snow-track surveys to test the efficacy of our camera surveys. We measured trail camera detection rates by survey week and location and we noted Canada Lynx activity and behaviours recorded by the cameras. The detection rate increased between January and April, reaching a peak of 8 Canada Lynx/100 camera-days in early April. Canada Lynx spent more time at camera sites displaying behaviours such as scent-marking and cheek-rubbing in late March. The combination of both snow-track and trail camera surveys was especially effective, with Canada Lynx detected at 77% of all monitored sites. Depending on survey objectives, it may be beneficial to conduct camera as well as other non-invasive survey methods for Canada Lynx during the breeding season, when survey efficacy and detection rates are maximized.

Este artigo examina como as questões dos surveys sobre democracia são estruturadas de modos diferentes, dependendo do emprego de uma definição idealista ou realista e da presença ou não de comparações com regimes alternativos. Começo mostrando medidas de democracia em países pós-comunistas que perguntam às pessoas se estão satisfeitas ou não com a democracia e pedem que a comparem com um padrão ideal. As seções posteriores apresentam os resultados de questões realistas do New Democracies Barometer, que pedem às pessoas para avaliar regimes do passado, do presente e do futuro - e alternativas não-democráticas historicamente familiares.

Determining Canada Lynx (Lynx canadensis) distribution is an important management need, especially at the southern extent of the species range where it is listed as threatened under the U. S. Endangered Species Act. We describe a systematic snowtrack based sampling framework that provides reliable distribution data for Canada Lynx. We used computer simulations to evaluate protocol efficacy. Based on these simulations, the probability of detecting lynx tracks during a single visit (8 km transect) to a survey unit ranged from approximately 0.23 for surveys conducted only one day after snowfall, to 0.78 for surveys conducted 7 days after a snowfall. If the survey effort was increased to three visits, then detection probabilities increased substantially from 0.58 for one day after snowfall to about 0.95 for surveys conducted 7 days after a snowfall. We tested the protocol in the Garnet Range, Montana, where most lynx were radio-collared. We documented a total of 189 lynx tracks during two winters (2001-2003). Lynx distribution based on snow-track surveys was coincident with the area defined through radio telemetry. Additionally, we conducted snow-track surveys in areas of western Wyoming where lynx were believed present but scarce. We detected a total of six lynx tracks during three winters (1999-2002). In Wyoming , where lynx presence was inferred from a few tracks, we verified species identification by securing genetic samples (hairs from daybeds) along track-lines.

To assess whether Western Chorus Frogs have declined in eastern Ontario, we conducted amphibian call surveys at 18 sites in the Cornwall area, where they were heard calling in 1990, as well as selected wetlands in the same area. Chorus frogs were detected at only 1 of the 18 original locations during surveys in 2001 and 2007. When survey locations with and without Chorus Frogs were considered, the site occupancy rate declined from 58% in 1990, to only 12% in 2007. Chorus Frogs appear to have declined in this area of eastern Ontario which is adjacent to documented declines in western Québec and northern New York.

During field surveys conducted in Albania in 2014, we encountered 90 species of butterflies. Anthocharis damone Boisduval, 1836 is a new species for the fauna of Albania while Apatura metis Freyer, 1829 is confirmed for the country. With these discoveries the number of butterfly species known to occur in Albania has risen to 200 and our surveys added many new sites for species considered rare and local in Albania. In addition, the life cycles of Lycaena ottomana (Lefèbvre, 1830) and Apatura metis from Albania are documented and discussed.

Surveys were conducted to assess Phytoseiidae (Acari: Mesositgmata) diversity in various habitats and ecosystems (including natural and agricultural areas) since 2008 in Turkey. This paper aims to provide a review of the Turkish species belonging to genus Amblyseius Berlese (Acari: Phytoseiidae) based on materials collected during these surveys as well as previous records. As a result, A. nemorivagus Athias-Henriot was found for the first time for Turkish fauna. In addition, unknown male of A. bryophilus Karg is described and illustrated. A revised identification key is provided for the 13 Amblyseius species found in Turkey. Validity of some previous Turkish records, and identity of A. meridionalis Berlese, are discussed. There are series of discrete species reported under the name A. meridionalis, none of them truly match with the original description in terms of shape of ventrianal shield. Our results indicated that A. kadzhajai Gomelauri, A. meridionalis, A. nemorivagus and A. obtusus (Koch) sensu Karg, were found only on moss. Amblyseius andersoni (Chant), A. herbicolus (Chant) and A. swirskii Athias-Henriot are common in agricultural ecosystems or higher plants. According to results, there is a different geographic distribution between these three species; A. swirskii is reported only from east Mediterranean, while A. herbicolus only from North-East (Black Sea region), A. andersoni is common in western Turkey. Only a few specimens of Amblyseius adjaricus Wainstein & Vartapetov and A. bryophilus were collected, from cultivated plants from Black Sea region. Therefore, potential of Turkish populations of these five species and their using possibilities in biological control are warranted in Turkey.

Resumo: Os medicamentos tem sido considerados instrumentos terapêuticos fundamentais que produzem curas, prolongam a vida e retardam o surgimento de complicações associadas a doenças, sendo responsáveis por parte significativa da melhoria da qualidade e expectativa de vida da população. São vários os fatores que influenciam o uso de medicamentos, entre eles se destacam os aspectos demográficos, sócio-econômicos e culturais da população e as políticas governamentais para o setor e o mercado farmacêutico. Analisar o padrão de utilização e os fatores associados a esse uso justifica-se devido ao crescente consumo dos medicamentos e o alto investimento do Estado com a Política de Assistência Farmacêutica no país. Os inquéritos de saúde são instrumentos importantes para obter informações relativas a utilização de medicamentos pelos diferentes segmentos sociais da população. O objetivo do presente estudo e analisar a prevalência da utilização de medicamentos segundo variáveis demográficas, sócio-econômicas e de comportamentos relacionadas a saúde da população, identificando os fatores associados ao uso. Trata-se de um estudo transversal, cujos dados foram obtidos do inquérito ISA-SP. A população de estudo e residente da área urbana de Campinas, com idade igual ou superior a 18 anos. A amostragem foi realizada em múltiplos estágios, estratificada e por conglomerados. O período recordatorio do uso de medicamentos foi os 3 dias anteriores a realização da entrevista. Utilizou-se a classificação ATC para a codificação dos medicamentos. As estimativas de prevalência e as analises de regressão consideraram as ponderações relativas ao desenho amostral, utilizando o software STATA 8.0. Utilizou-se o teste qui-quadrado para verificar a associação estatística entre a variável dependente e as variáveis independentes. Foram estimadas razoes de prevalência ajustadas por sexo e idade e respectivos IC 95% utilizando regressão múltipla de Poisson. Foi desenvolvido um modelo hierárquico de regressão múltipla de Poisson para ajuste de variáveis de confundimento. A prevalência global do uso de medicamentos foi de 48,5%. Observou-se que mulheres referiram maior consumo de medicamentos que os homens e que a media de medicamentos aumentou com a idade em ambos os sexos. Apos ajuste por idade e sexo, observa-se que as variáveis religião, renda, numero de doenças crônicas, presença de morbidade nos últimos 15 dias e transtorno mental comum permaneceram significativamente associadas ao uso de medicamentos. No modelo hierarquizado final verificou-se consumo significativamente maior de medicamentos nas pessoas no sexo feminino, nas idades de 40 anos ou mais, renda familiar superior a 4 salários mínimos, religião evangélica, morbidade referida nos últimos 15 dias e apresentando doenças crônicas (uma a duas, três ou mais). Os medicamentos mais consumidos foram os que atuam no sistema cardiovascular, sistema nervoso e fitoterápicos. O perfil de utilização de medicamentos em Campinas encontra-se dentro dos parâmetros observados em outros estudos. Os resultados podem subsidiar ações da Política de Assistência Farmacêutica, visando a ampliação do acesso e a promoção do uso racional de medicamentos.
Abstract: The drugs have been considered key therapeutic tools that produce healing, prolong life and delay the onset of complications associated with diseases, accounting for a significant part of improving the quality and life expectancy of the population. There are several factors influencing the use of drugs, among them stand out the demographic, socioeconomic and cultural population and government policies for the sector and the pharmaceutical market. To analyze the pattern of use and factors associated with such use is justified due to the increasing consumption of drugs and the high investment from the State Pharmaceutical Assistance Policy in the country. Health surveys are important tools for information concerning the use of drugs by different social segments of the population. The aim of this study is to analyze the prevalence of use of medicines according to demographic, socioeconomic and health-related behaviors of the population, identifying the factors associated with use. This is a cross-sectional study with data obtained from the survey ISA-SP. The study population is resident in the urban area of Campinas, aged over 18 years. Sampling was performed in multiple stages, stratified by conglomerates. The recall period of drug use was the three days prior to the interview. We used the ATC classification for the coding of medicines. The prevalence estimates and regression analysis considered the weights from the sample design, using STATA 8.0. We used the chi-square test to verify the statistical association between the dependent and independent variables. We estimated adjusted prevalence ratios by sex and age and their respective 95% using Poisson multiple regression. We developed a hierarchical model of Poisson multiple regression to adjust for confounders. The overall prevalence of drug use was 48.5%. It was observed that women reported higher consumption of drugs than men and that the mean number of medications increased with age in both sexes. After adjusting for age and sex, it is observed that the variables of religion, income, number of chronic diseases, presence of morbidity in the last 15 days and common mental disorder remained significantly associated with drug use. In the final hierarchical model was found significantly higher consumption of medicines in people in females, ages 40 years or more family income than 4 minimum wages, evangelical religion, reported morbidity in the last 15 days and presenting chronic diseases (one two, three or more). Most frequently consumed drugs were acting on the cardiovascular system, nervous system and herbal medicines. The profile of drug utilization in Campinas is within the parameters observed in other studies. The results can support the actions of Pharmaceutical Policy, aimed at expanding access and promoting rational drug use.

O principal objetivo deste trabalho é mostrar que é possível buscar por estrelas pobres em metais a partir da premissa de que uma grande fração destas será rica em carbono. Essa hipótese ainda não havia sido verificada pois muitas das chamadas estrelas CEMP (Carbon Enhanced Metal-Poor) foram negligenciadas em estudos anteriores devido à forma como foram executadas as buscas por estas estrelas. Estes objetos são importantes pois assumem o papel de registros fósseis das primeiras gerações estelares, uma vez que retêm em suas atmosferas informações vitais acerca da composição química do meio em que foram geradas. Por não apresentarem bandas moleculares intensas de carbono em seus espectros, muitas dessas estrelas não foram selecionadas para estudos em média/alta resolução. Este trabalho fornece, a partir do estudo da parte estelar do projeto HES (Hamburg/ESO Survey), que contém 4.404.908 objetos, dois novos índices de linha para a região da banda G do CH, em 4304 Å. Estes, pelo fato de possuírem uma largura de banda de 200 Å, conseguem superar falhas dos índices anteriormente definidos e representam com fidelidade as principais características desta região. Após uma análise detalhada da base de dados, e do cálculo dos novos índices de linha para todos os objetos disponíveis, foram identificadas com o telescópio SOAR 132 estrelas pobres em metais inéditas na literatura, sendo que 51% destas possuem metalicidades abaixo de [Fe/H] < -1.0 e apresentam consideráveis enriquecimentos em carbono ([C/Fe] > +0.5). Já para as estrelas encontradas com [Fe/H] < -2.5, a fração de estrelas com abundâncias de carbono [C/Fe] > +1.0 chega a 80%. Estimativas de abundâncias de elementos químicos tais como bário e estrôncio revelam que, mesmo com parâmetros atmosféricos e abundâncias de carbono semelhantes, as estrelas analisadas por este trabalho possuem mais de um tipo de cenário possível para sua formação. Neste ínterim, os objetos adicionados à literatura contribuem tanto para o aumento da estatística de estrelas pobres em metais quanto para testes de modelos teóricos de enriquecimento químico da Via Láctea. Finalmente, este trabalho também gerou uma lista de 6123 candidatas a estrelas CEMP inéditas na literatura.
The main goal of this work is to show that is possible to search for metal-poor stars based on the premise that a large fraction of these will be carbon-rich. This hypothesis had not yet been verified because many of the so-called CEMP (Carbon Enhanced Metal-Poor) stars were neglected in previous studies due to the design of the search for metal-poor stars with carbon enhancements. Those objects play a major role as fossil records of the very first generation of stars, since they carry in their atmospheres vital informations concerning the chemical composition of the medium where they were formed. By not showing strong carbon molecular bands in their spectra, many of those stars were not selected for follow-up studies in medium/high resolution. This work provides, based on the study of the stellar part of the HES (Hamburg/ESO Survey), two new line indices for the G band (4304 Å) that, by having a line band of 200 Å, can overcome the flaws of the previously defined indices and also truly represent the main features of this region. After an extensive analysis of the database and the calculation of the line indices for all the available objects, 132 new metal-poor stars were identified with the SOAR telescope, being that 51% of those stars with [Fe/H] < 1.0 present considerable carbon enhancements ([C/Fe]> +0.5). For the observed stars with [Fe/H] < 2.5, the fraction of objects with [C/Fe] > +1.0 rises up to 80%. Abundance estimates for barium and strontium show that, even with similar atmospheric parameters and carbon abundances, the stars analysed in this work have more than one possible formation scenario. Finally, this work also contributes with a 6123 CEMP star candidate list of unpublished objects.

Introdução. Inquéritos domiciliares têm sido utilizados em estudos epidemiológicos desde o início do século passado. Com o passar do tempo, os métodos de realização de entrevistas foram se aperfeiçoando, possibilitando maior rapidez e exatidão nas informações obtidas. As entrevistas realizadas via telefone tornam o processo mais fácil, ágil e de menor custo. Objetivo. Comparar os moradores do município de São Paulo que possuíam telefone fixo em sua residência, com os que disseram não possuir o referido aparelho, quanto a variáveis demográficas, de condições de vida, estilo de vida, estado de saúde e também quanto ao uso e acesso aos serviços de saúde. Metodologia. Utilizando o módulo survey do pacote estatístico Stata em sua versão 9.2, foi feita uma caracterização do perfil desses dois grupos de entrevistados (com e sem telefone fixo). Foram calculados também, os vícios que a não cobertura por parte da população sem telefone ocasiona às estimativas e foi verificado como um ajuste de pós-estratificação diminui este vicio. Resultados. Dos 3333 entrevistados na cidade de São Paulo, 77,7% possuíam telefone fixo residencial; foi detectada associação estatisticamente significante entre a presença de telefone fixo e as variáveis: naturalidade, raça/cor, religião, situação conjugal, escolaridade do chefe de família, renda, tabagismo, alcoolismo, presença de morbidade referida, hipertensão, auto-avaliação em saúde, realização de mamografia, exame de próstata, consultas odontológicas, consumo de medicamentos e utilização do SUS para a realização dos exames de saúde. Ao se retirar da análise, a população sem telefone fixo, as estimativas de exame de pré-natal e próstata, tabagismo, alcoolismo, auto-avaliação de saúde, consultas odontológicas e a utilização do SUS para os exames de pré-natal e Papanicolaou foram as que tiveram maior vício. Após o ajuste de pósestratificação, houve uma melhora em todas as estimativas que estavam associadas à posse do telefone fixo, porém o vício não foi reduzido por completo. Conclusão. A exclusão dos moradores sem aparelho telefônico é uma das principais limitações e fonte de vício em pesquisas via telefone, mesmo em lugares onde a cobertura seja considerada razoável. Este obstáculo não deve ser considerado um impedimento, no entanto, algumas precauções e ajustes terão que ser utilizados para se reduzir os vícios, contribuindo para a estimação e interpretação correta dos resultados, já que estes levantamentos via telefone servem não apenas para se conhecer o estado de saúde da população, mas também contribuem para a orientação no planejamento de ações e novas políticas de saúde pública.
Introduction. Household surveys have been widely used in epidemiologic studies since the beginning of the 20th century. The methods used in interviews have improved and become a more precise way to obtain information. Telephone interviews make the whole process easier, quicker and less expensive. Objective. To compare households with and without telephone living in São Paulo city analyzed by demographic life conditions, life style, health state and access to health services. Methods. Using Stata 9.2 (survey package), the residents were separated in two groups (with and without telephone). The biases created by the non-coverage of nontelephone respondents from the data bank were estimated and a poststratification adjustment was applied with the purpose of reducing this bias. Results. About 77.7% of respondents reported owning a telephone in the city of São Paulo which was statistically associated to region of birth, race, religion, marital status, schooling of household head, income, smoking status, alcoholism, morbidity, hypertension, self-health status, breast and prostate exam, dental care, medicine use, and also the utilization of Brazilian National Health System (SUS) in health exams. Excluding the respondents without telephone from the analysis, prevalence estimates of prenatal and prostate exam, smoking status, alcoholism, self-health status, dental care and the utilization of Brazilian National Health System in prenatal care and Papanicolaou exam were extremely affected by non-coverage bias. Nevertheless after post-stratification adjustment, the bias has been diminished to all variables associated to telephone ownership, but not completely. Conclusion. The exclusion of persons without telephone is one of the main limitations, as well as, is a great source of bias in telephone surveys, even in areas where the coverage is relatively high. However, it should not be considered a barrier, since some precautions are taken in order to reduce bias, improve the estimates and provide correct interpretation of results, the telephone survey is not only important to (get to) know the population health status, but it also contribute to supporting new public health action.

Base Teórica: Apesar dos avanços alcançados na última década por meio das ações de controle da tuberculose, esta endemia permanece um problema no Brasil. Atraso no diagnóstico e tratamento dos casos de tuberculose é o fator de maior impedimento no controle da tuberculose. Os objetivos desse estudo foram descrever a trajetória dos pacientes com diagnóstico de tuberculose antes do início do tratamento em unidade de referência, analisando a demora do paciente e o número de unidades de saúde visitadas antes do início do tratamento para tuberculose. Método: Estudo transversal realizado em dois serviços de tisiologia. Pacientes com idade ≥18 anos e com diagnóstico de tuberculose pulmonar responderam um questionário que avaliava: trajetória até o diagnóstico, tempo até o diagnóstico e fatores associados com o atraso no diagnóstico. Resultados: A média de idade dos pacientes foi de 40,4 ± 16,1. Foi encontrada uma mediana de 20 dias no atraso dos pacientes. Os fatores associados negativamente com atraso do paciente em um modelo de análise multivariada foram perda de peso e ter procurado tratamento por causa do primeiro sintoma. Também foi encontrado que 44,8% relataram incorretamente o modo de transmissão tuberculose. Além disso, o local de primeiro atendimento para 37,3% dos pacientes foi uma emergência de hospital público. Conclusão: Foi encontrada uma mediana de 20 dias no atraso dos pacientes até o diagnóstico da tuberculose em dois serviços de saúde e em uma região com alta prevalência da doença, os fatores associados a este atraso na análise multivariada foram perda de peso e ter procurado tratamento por causa do primeiro sintoma.
Background: Despite the advances in the last decade through the actions of tuberculosis control, this remains a problem endemic in Brazil. Delays in diagnosis and treatment of tuberculosis cases are major impeding factors in the control of tuberculosis. The objectives of this study were to describe the health care seeking behavior of tuberculosis patients, assessing patient delay and the number of health care facilities visited before the start of tuberculosis treatment. Methods: Cross-sectional study in two tuberculosis services. Patients aged ≥18 years old and diagnosed with pulmonary tuberculosis answered a questionnaire that evaluated: path to diagnosis, time to diagnosis and factors associated with delay in diagnosis. Results: The mean age of all patients was 40.4 ± 16.1 years. We found a median patient delay of 20 days. The factors associated negatively with patient delay in multivariate analysis were weight loss, and have sought treatment because of the first symptom. We also demonstrated that 44.8% of patients incorrectly reported the mode of transmission of tuberculosis. In addition, the local of first attendance was an emergency room of public hospitals in 37.3% of patients. Conclusions: We demonstrated that the median patient delay in tuberculosis diagnosis in two tuberculosis services in a region with a high prevalence of tuberculosis was 20 days, and the factors associated with this delay in multivariate analysis were weight loss, and have sought treatment because of the first symptom.

Este estudo transversal foi realizado com 111 adultos de 30 a 59 anos, em duas Unidades Básicas de Saúde da cidade de São Paulo. O exame clínico foi realizado por um examinador para avaliar as condições da cárie dentária, seguindo os critérios da Organização Mundial da Saúde. Foram aplicados questionários para obter dados socioeconômicos, demográficos, comportamentais. Para avaliar qualidade de vida na saúde bucal foi aplicado o instrumento Oral Health Impact Profile (OHIP-14). Utilizaram-se, para perda dentária, os dentes perdidos (limite 7 dentes perdidos) e para o grupo de alta experiência de cárie o SiC - Significant Index Caries (limite 25,5), e na avaliação da qualidade de vida o OHIP-14 foi dicotomizado em ter presença e ausência de impacto. Foi realizada uma análise descritiva e utilizado o teste do qui-quadrado, com o nível de significância de 5%. A média de idade foi 42 anos. O CPOD foi de 18,55 (+6,7), sendo a média de dentes cariados 1,6 (+1,8), perdidos de 8,6 (+6,5), e obturados 8,2 (+5,1). A perda dentária foi associada com a limitação funcional (p=0,013), desconforto psicológico (p=0,017), incapacidade física (p=0,002) e incapacidade social (p=0,036). O grupo de alta experiência de cárie foi associado com incapacidade física (p=0,004) e limitação física (p=0,025). A utilização do indicador subjetivo OHIP-14 mostrou que a incapacidade física foi associada tanto à perda dentária como ao grupo de alta prevalência de cárie, sendo importante instrumento para medir o impacto da saúde bucal na qualidade de vida
Abstract: The objectives of this study were to understand the conditions of oral health status of adults users from the Unified Health System - UHS, to verify the association between tooth loss and the impact on quality of life and see if the high caries experience interferes in the quality of life of this population. A survey was conducted with 111 adults from 30 to 59 years in two Basic Health Units in São Paulo. The clinical examination was conducted by an examiner to assess the conditions of dental caries, following the criteria of World Health Organization. Questionnaires were used to obtain demographic, socioeconomic and behavioral factors. To asses quality of life in oral health was applied Oral Health Impact Profile (OHIP-14) instrument. It was used to tooth loss, a limit of 7 missing teeth, and the group of high caries experience, SiC - Significant Caries Index (limit 25.5), and assessing the quality of life the OHIP-14 it was dichotomized into have presence and absence of impact. It was performed a descriptive analysis and used the chi-square rejection level of 5%. The mean age was 42 years. The DMFT was 18.55 (+6.7), with an average of 1.6 decayed teeth (+1.8), missed 8.6 (+6.5), and filled 8.2 (+5.1). Tooth loss was associated with functional impairment (p=0.013), psychological distress (p=0.017), physical disability (p=0.002) and disability social (p= 0.036). The group of high caries experience was associated with physical disability (p=0.004) and physical impairment (p=0.025). The use of subjective indicator OHIP-14 showed that physical impairment was associated with both tooth loss as the group of high caries experience, an important tool to measure the impact of oral health on quality of life

Introdução - A preocupação com a qualidade e disseminação dos dados em inquéritos é crescente no mundo. A integração entre banco de dados, planejamento da amostra, questionário e entrada de dados é fundamental para que resultados observados sejam válidos e precisos. A bibliografia pesquisada apontou que os inquéritos raramente produzem arquivos organizados, padronizados e prontos para disseminação, o que impossibilita estudar diferentes objetos de investigação com base em informações já coletadas. Objetivos - Implementar modelo hierárquico para entrada de dados em inquéritos epidemiológicos. Métodos - Foi utilizada a UML (Linguagem de Modelagem Unificada) para o projeto lógico e o Makeview do Epi Info para obtenção das estruturas de dados. Os testes foram feitos em um setor censitário do inquérito Acesso a Medicamentos - FAPESP. A documentação foi gerada no Makeview com ajuda de uma macro do Excel. Resultados - O modelo permite criar arquivos relacionais flexíveis, conforme a necessidade do objeto de estudo, com unidades estatísticas escolhidas dentre os 4 níveis hierárquicos: setor censitário, domicílios, indivíduos e questões específicas. Conclusão - A possibilidade de criar infinitas visões sobre os dados representa um avanço em comparação com o modelo plano. Deve ser usado como padrão em inquéritos epidemiológicos, pois permite estudar o efeito de conglomeração das unidades de análise, além de viabilizar a disseminação com dados organizados. O Epi Info pode ser usado para implementar modelos hierárquicos que considerem as variáveis do plano amostral.
Introduction - Concern about the quality and data dissemination in surveys is growing in the world. The integration between database, sample planning, questionnaire and data entry is fundamental to the accuracy and validity of the results. The bibliography showed that investigations rarely produce organized files, standardized and ready to dissemination, which makes impossible the study of various investigation objects based on information already collected. Goals - Implement hierarchical model for data entry in epidemiological surveys. Methods - It was used the UML (Unified Modeling Language) for the logical project and the Epi Info Makeview to obtain the data files. The tests were made in a census block of the Access to Medicines - FAPESP survey. The documentation was generated in Makeview with help of an Excel macro. Results - The model allows you to create flexible relational files, as the need to study subject, with statistical units chosen amongst the 4 hierarchical levels: census blocks, households, individuals and specific issues. Conclusion - The ability to create infinite views on the data represents a breakthrough in comparison to the flat files. It should be used as standard in epidemiological surveys, it allows studying the effect of conglomeration of analysis\' units, besides enabling the dissemination with organized data. The Epi Info can be used to implement hierarchical models that consider the variables of a sampling plan.

Resumo: A concepção de que os adolescentes raramente ficam doentes e o habito de justificar qualquer problema de saúde seja físico ou mental como "normal" ou característico desta etapa da vida tem limitado a atenção a saúde dos adolescentes e consequentemente as pesquisas nesta área. O controle das doenças infecto-contagiosas, das doenças respiratórias na infância, a maior sobrevida de neonatos extremos, a correção cirúrgica de cardiopatias congênitas, assim como as mudanças dos hábitos alimentares e de atividade física entre crianças e adolescentes podem estar aumentando a prevalência de doenças crônicas em adolescentes. O objetivo deste estudo transversal de base populacional foi estimar a prevalência de doenças crônicas diagnosticadas e de problemas de saúde referidos segundo variáveis demográficas e socioeconômicas e identificar as características demográficas e socioeconômicas dos adolescentes do município de Campinas. As informações de 929 adolescentes de 10 a 19 anos foram obtidas por meio de entrevistas domiciliares realizadas no Inquérito de Saúde do Município de Campinas, ISACamp 2008/09. Foram utilizadas estatísticas descritivas, teste de associação pelo ?2, razões de prevalência e intervalos de confiança de 95%. Para analise múltipla foi realizada Regressão de Poisson. Verificou-se que entre os adolescentes de Campinas a prevalência de ao menos uma doença cronica diagnosticada foi de 19,17% (IC 95%: 15,67 - 23,22), sendo asma a de maior prevalência 7,59% (IC95%: 6,01-9,54), hipertensão (1,07%) e diabetes (0,21%) foram pouco prevalentes nos adolescentes. Problemas de saúde referidos tiveram prevalência de 61,53% (IC95%: 54,61- 68,02), alergia 40,39% (IC 95%: 34,90-46,13) e dores de cabeça freqüente/enxaqueca 24,83% (IC95%: 20,35-29,92) foram os problemas de saúde referidos mais frequentes. Após análise ajustada para idade e sexo observou-se que faixa etária de 15 a 19 anos, não frequentar escola, ter filhos e ser obeso estavam associados a doença crônica diagnosticada. Somente sexo feminino apresentou associação a problemas de saúde referidos após a análise múltipla. A prevalência de problemas de saúde referidos entre os adolescentes de Campinas mostrou-se elevada e três vezes maior do que a prevalência de doenças crônicas diagnosticadas. A idéia de que a adolescência é uma fase da vida na qual pouco se adoece deve ser refutada
Abstract: The concept that adolescents are rarely ill and the habit of regarding any health problem they have, whether physical or mental, as normal or typical of that period of life, have limited the health care for them and, in consequence, research in that field. The control of childhood infectious diseases, respiratory system disorders, longer lifespan for extreme neonates, corrective surgery of congenital heart abnormalities, as well as changes in eating habits and physical activity among children and adolescents, may be increasing the prevalence of chronic diseases among adolescents. The aim of this population-based cross-sectional study was to identify the demographic and socioeconomic characteristics of adolescents in the municipality of Campinas, and analyze the prevalence of diagnosed chronic diseases and health problems reported using demographic and socioeconomic variables. The information from 929 adolescents aged between 10 and 19 was obtained through household interviews in a health survey conducted in the municipality of Campinas - ISACamp 2008/09. Descriptive statistics, the chi-squared test of association, prevalence proportions, and 95% confidence intervals were used. The multiples analysis was performed using Poisson Regression. It was verified that the prevalence of diagnosed chronic diseases among adolescents in Campinas was 19.17% (95% CI: 15.67-23.22), asthma being the most prevalent 7,59% (95% CI: 6.01-9.54), hypertension(1,07%) and diabetes (0,21) were less prevalent in adolescents. The prevalence of health problems reported was 60.99% (95% CI: 54.12-67.46), allergies 49,39% (95% CI: 34.90-46.13) and frequent headaches/migraine 24,83% (95% CI: 20.35-29.92) showing the highest frequency. After the adjusted analysis was conducted, it was observed that while the 15-19 age group, not attending school, having children and being obese were associated with diagnosed chronic diseases. Only female sex was associated with health problems reported after multiple analyses. The prevalence of health problems reported in adolescents from Campinas was significant, being three times higher than that of diagnosed chronic diseases. The concept that adolescence is the period of life during which illnesses are rare should be refuted

Resumo: Os adolescentes são considerados um grupo vulnerável do ponto de vista nutricional, pois estão submetidos a processos concomitantes de natureza fisiológica, psicológica e social que podem interferir no padrão alimentar. Dentre os fatores determinantes da saúde, a alimentação exerce grande influência no pleno desenvolvimento do indivíduo e na prevenção de possíveis agravos à saúde. Em síntese, os estudos apresentados neste trabalho demonstram problemas no padrão alimentar dos adolescentes, caracterizado por elevado consumo de alimentos ricos em energia, gorduras, principalmente a saturada e o colesterol, açúcar refinado, sódio, em detrimento a alimentos saudáveis como as frutas, as hortaliças, o leite e os tradicionais, arroz e feijão. O objetivo deste estudo foi avaliar os fatores demográficos, socioeconômicos e os comportamentos relacionados à saúde e morbidade associados à qualidade da dieta de adolescentes, residentes no município de Campinas, São Paulo, Brasil. O recordatório alimentar de 24h proveu as informações necessárias para avaliar a qualidade da dieta por meio do Índice de Qualidade da Dieta (IQD) adaptado para a realidade brasileira. Os dados foram obtidos do "Inquérito de Saúde no Estado de São Paulo" (ISASP), uma pesquisa de base populacional, conduzida entre 2001 e 2002. O presente estudo analisa 409 indivíduos de 12 a 19 anos, de ambos os sexos. Os adolescentes foram obtidos por amostra estratificada e por conglomerados. Utilizou-se a regressão de Poisson para avaliar a associação entre o 1º quartil de dietas (dietas de pior qualidade) e as variáveis independentes. A regressão linear múltipla foi utilizada para identificar os fatores associados aos diferentes componentes do IQD. Os principais resultados deste estudo foram: baixo escore médio do IQD na população estudada; menor prevalência de dietas no 1º quartil do IQD no segmento de melhor nível de escolaridade do chefe da família (12 anos ou mais). Os componentes do IQD que apresentaram as menores pontuações foram: frutas, verduras e legumes e leite e produtos lácteos. O componente com maior escore foi o de carnes e ovos. Os segmentos de adolescentes que apresentaram significativa maior pontuação de cada um dos componentes do IQD, em relação às respectivas categorias de referência, foram: adolescentes de religião evangélica, quanto ao grupo dos pães, cereais, raízes e tubérculos; melhor nível de escolaridade do chefe da família, quanto ao grupo das verduras e legumes; segmentos de maior renda familiar, no grupo das frutas; melhores níveis de escolaridade do chefe, no grupo do leite e produtos lácteos; IMC de sobrepeso/obesidade, no componente de carnes e ovos; sexo feminino, no componente sódio; e melhores níveis de renda familiar, no componente variedade da dieta. Por outro lado, os segmentos de adolescentes que apresentaram significativa menor pontuação de cada um dos componentes do IQD, em relação às respectivas categorias de referência, foram: IMC de sobrepeso/obesidade, no grupo das frutas; raça/cor não-branca, no grupo do leite e produtos lácteos; renda familiar mais elevada, no componente das leguminosas; e sexo feminino, no componente gordura total.
Abstract: Adolescents are considered a vulnerable group from a nutritional perspective, since they are under concomitant processes from physiological, psychological and social natures, which may interfere in the dietary pattern. Among the determining health factors, alimenting plays an important role in an individual plain development and on preventing possible health threats. In summary, the study presented in this work demonstrates problems on the dietary pattern of adolescents, known for an elevated intake of aliments that are rich on energy, fat -mainly saturated and cholesterol -, refined sugar, sodium, at the cost of healthy food, such as fruits, vegetables, milk and traditional, rice and beans. The objective of this study was to evaluate the demographic, social-economical and the behavioral factors related to health and morbidity, associated to the diet quality of adolescents from the city of Campinas, in S? Paulo, Brazil. The 24-hour recall method provided the necessary data to evaluate the diet quality through the Healthy Eating Index (HEI) adapted to the local reality. Data was obtained from the "Health Inquiry of the State of S? Paulo" (ISA-SP), a population-based cross-sectional research, conducted between 2001 and 2002. The present study examines 409 individuals with ages from 12 to 19 years, from both genders. Adolescents were obtained by stratified clustered sampling. Poisson Regression was used to evaluate the association between the first diet quartile (worst quality diets) and the independent variables. Multiple linear regression was utilized to identify the associated factors to the different HEI components. The main results of this study were: low HEI score from the studied population; less prevalence of diets on the first HEI quartile on the greater schooling levels for heads of families segment (age of 12 or more). The HEI components that presented the lowest scores were: fruits, vegetables, pulses, milk and dairy products. The highest scoring components were meats and eggs. The segments of adolescents that presented significantly higher score of each component of HEI, in relation to their respective reference categories, were: adolescents from evangelical religion, about the group of cereals; better levels of schooling about the vegetables group; greater household income segments about the fruits group; better schooling levels of head of family, about the milk and dairies products group; overweight/obesity BMI, in the meat and eggs component; female gender, in the sodium component; and better household income levels, in the food variety component. Furthermore, the segments of adolescents that presented significant lower scores of each component of the HEI, in relation to their reference categories, were: overweight/obesity BMI, in the fruits group; race/non-white, about the milk and dairies products group; higher household income levels in the legumes component; and female gender, in the total fat component.

<em>Abstract</em>.—Striped bass <em>Morone saxatilis</em> provide important commercial and recreational fisheries in many Atlantic coast states, in addition to providing popular recreational reservoir fisheries in numerous inland states. Measurements of fishery-dependent data such as harvest, catch, and effort are essential to determining whether management actions are effective. Many states, including Texas, use creel-survey methods for measuring striped bass catch and effort statistics for recreational anglers. However, a systematic overview of the performance of the various types of creel surveys, or creel surveys in general, for measuring striped bass catch and effort has not been performed previously. In many states, both roving and access creel surveys are used, and effort may be allocated using unequal probabilities. In fisheries with low harvests of <em>Morone </em>spp., survey statistics for these fish typically have high relative standard errors (RSE), from 30% to 115%.As directed effort increases, the RSE typically decreases; in systems with high angling effort directed at striped bass, RSE is much lower (e.g., 18% in Lake Texoma, Texas–Oklahoma).We used these and other data from striped bass creel surveys throughout the United States to assess the reliability of estimates from various methods. We recommend making survey sampling effort coincide with the fishing effort. While it may be possible to improve the precision by increasing the amount of manpower devoted to the current creel survey, stratifying or using unequal spatial and temporal probabilities are techniques more likely to improve precision in a cost-effective manner. Once the data have been collected, we show how using model-based estimation, such as using Kalman filters or empirical Bayesian estimation, could also prove advantageous.

<em>Abstract</em>.— Hydroacoustic surveys have proven valuable for estimating reservoir forage fish abundance but are more challenging for adult predators such as striped bass <em>Morone saxatilis</em>. Difficulties in assessing striped bass in reservoirs include their low density and the inability to distinguish species with hydroacoustic data alone. Despite these difficulties, mobile hydroacoustic surveys have potential to provide useful data for management because of the large sample volume compared to traditional methods such as gill netting and the ability to target specific areas where striped bass are aggregated. Hydroacoustic estimates of reservoir striped bass have been made using mobile surveys, with data analysis using a threshold for target strength in order to focus on striped bass-sized targets, and auxiliary sampling with nets to obtain species composition. We provide recommendations regarding survey design, based in part on simulations that provide insight on the level of effort that would be required to achieve reasonable estimates of abundance. Future surveys may be able to incorporate telemetry or other sonar techniques such as side-scan or multibeam in order to focus survey efforts on productive habitats (within lake and vertically). However, species apportionment will likely remain the main source of error, and we see no hydroacoustic system on the horizon that will identify fish by species at the spatial and temporal scale required for most reservoir surveys. In situations where species composition can be reliably assessed using traditional gears, abundance estimates from hydroacoustic methods should be useful to fishery managers interested in developing harvest regulations, assessing survival of stocked juveniles, identifying seasonal aggregations, and examining predator–prey balance.

<em>Abstract</em>.—The Carolina madtom <em>Noturus</em><em> furiosus</em> is a rare fish endemic to the Tar and Neuse River basins of North Carolina. Surveys over the past three decades suggest declines in its distribution and abundance. We conducted 60 surveys at 30 sites with historical survey records in April–August of 2007 to assess the current status of the Carolina madtom. Data were compared to historical records to detect any temporal change in occurrence. We also estimated the proportion of sites occupied (occupancy) and detection probabilities for a subset of sites with the computer software package PRESENCE using repeat detection/nondetection data. Additionally, we examined aspects of the general biology and population structure of the Carolina madtom (e.g., spawning period, size structure, catch per unit effort). Results indicate a significant decrease in occurrence in the Neuse River basin (χ<sup>2</sup> = 41.6, <em>p</em> < 0.05). Frequencies of occurrence decreased from 0.80 to 0.13 between 1960s and 2007 data. A robust population was detected at only one site surveyed in the Neuse River basin. No significant temporal change in occurrence was seen in the Tar River basin (χ<sup>2</sup>= 0, <em>p</em> = 1). Occupancy estimates generated from PRESENCE were similar to observed frequencies of occurrence due to high detection probabilities. Spawning and nesting behaviors were observed from mid-May through early July. Catch-per-unit-effort data and length-frequencies suggest strong recruitment in most Tar River basin populations and in one Neuse River basin population. Conservation measures are needed throughout the range of the Carolina madtom and especially in the Neuse River basin where there is a high risk of extirpation.

Abstract.—Atlantic sturgeon <em>Acipenser oxyrinchus</em> and lake sturgeon <em>A. fulvescens </em>in the middle St. Lawrence estuary are under consideration for designation as “endangered” or “vulnerable” species. A potential threat to these species is the disposal of dredged sediments in an area where young-of-the-year and juvenile Atlantic sturgeon concentrate. The objectives of this study were (1) to study the short-term and cumulative impacts, if any, of the dumped sediments on the abundance, distribution, and movements of the two sturgeon species downstream of the disposal area, and (2) to investigate the usefulness of acoustic surveys for assessing sturgeon density and distribution. A two-phase, combined acoustic-trawl survey was conducted to describe sturgeon distributions and produce concurrent acoustic and trawl estimates of the relative abundance of demersal fish within the area (lake sturgeon and Atlantic sturgeon were presumed to dominate the acoustic echoes). This series of surveys was the first known attempt to quantify sturgeon abundance and distribution with a vertically deployed echo sounder. The results showed good correspondence between the two methods. Replicated sampling also showed the repeatability of the acoustic technique and stability in demersal fish distribution on a scale of days. The acoustic surveys indicated that the spatial distribution of demersal fishes was dependent on substrate, as these fishes avoided areas of dredged sediment dumping and associated sand dunes. Our study showed that under certain conditions, acoustic-trawl surveys can reliably assess sturgeon density and distribution.

<em>Abstract</em>.—In Ohio reservoirs, a perceived excess of available gizzard shad <em>Dorosoma cepedianum </em>prey and poor recruitment of stocked walleyes <em>Sander vitreus </em>during the 1970s resulted in research to develop and expand a program to stock saugeyes (walleye × sauger <em>S. canadensis</em>), a hybrid better suited for shallow, productive, and turbid reservoirs with short water-residence times. Development of successful production techniques increased saugeye stocking from fewer than 1.2 million to 6–10 million fingerlings (28–42 mm) per year during 1980 through 1990, presenting the challenge of determining stocking rates suited to available prey. To improve <em>Sander </em>spp. stocking practices, we assessed prey supply by quantifying fish biomass in Ohio reservoirs using acoustic technology. Fish biomass varied from 10 to 897 kg/ha as estimated by 53 acoustic surveys conducted on 16 reservoirs during 1999–2006. Among 15 variables associated with reservoir productivity, 84% of the variability in fish biomass was explained by watershed area, trophic state, reservoir area, and reservoir volume; watershed area plus trophic state explained 77% of this variability. Dominance of fish prey smaller than 150 mm, which represented more than 80% of fishes sampled in acoustic surveys, revealed that reservoir fish biomass largely reflected the upper limit of prey fish biomass morphologically available to age-1 and older <em>Sander </em>spp. Gizzard shad represented more than 50% of the fishes captured in 92% of gill-netting surveys conducted in conjunction with acoustic surveys. Unexpectedly, reservoirs with extensive prey biomass occasionally had poor recruitment for <em>Sander </em>spp., and these reservoirs often were stocked at lower rates than ones with better recruitment. Fisheries managers in Ohio can improve stocking practices by using acoustic surveys to predict reservoir capacity for stocked sport fish based on reservoir attributes, then applying these results to details of reservoir-specific recruitment of stocked fishes and their consumptive demand. Refining this supply and demand approach will require continual progress in understanding reservoir ecosystems and their watersheds.

<em>Abstract.</em>—The principal aim of this study is to describe the distribution patterns of abundance and biomass, on a seasonal and bathymetric basis of the main macrourid species from the Spanish Gulf of Cadiz. The results from 23 bottom-trawl surveys carried out in the study area in spring and autumn of 1993–2006 were analyzed. The most abundant species captured were common Atlantic grenadier <em>Nezumia aequalis </em>and saddled grenadier <em>Coelorinchus coelorhincus. </em>In terms of biomass, softhead grenadier <em>Malacocephalus laevis </em>was the third most important species and bluntsnout grenadier <em>Nezumia sclerorhynchus </em>and glasshead grenadier <em>Hymenocephalus italicus </em>were the least abundant species. Of the five species caught in the surveys, only <em>N. aequalis</em>, <em>M. laevis </em>and <em>C. coelorhincus </em>were analyzed in detail; their yields expressed in number of individuals/h represented the higher values and showed higher yields in spring than in autumn, suggesting a seasonal pattern of abundance. However, <em>C. coelorhincus </em>did not show this pattern except between 1999 and 2004. <em>N. aequalis </em>showed the widest bathymetric range. The observed yields in the depth gradient for the three species revealed species-specific preferences for a determinate depth range. In relation to mean total size, larger individuals of <em>M. laevis </em>and <em>N. aequalis </em>were observed during the March surveys. <em>C. coelorhincus </em>was the only species that showed a slight increase in mean size with increasing depth.

<em>Abstract</em>.—The Guadalupe Bass <em>Micropterus treculii</em> is a central Texas endemic black bass species occurring only in streams and rivers draining the Edwards Plateau ecoregion. It is designated the state fish of Texas and provides a popular sport fishery. In addition to being a popular sport fish, it is listed as a species of special concern due to habitat degradation and hybridization with Smallmouth Bass <em>M. dolomieu</em>. Past socioeconomic surveys of Texas black bass anglers have focused primarily on reservoir fisheries while little is known about fishing patterns, economic impact, and preferences of river and stream anglers. A Web-based open-access survey was used to determine fishing characteristics, assess attitudes and quantify the economic impact of anglers fishing rivers and streams in a 24-county region of Texas from August 20, 2011 to December 20, 2012, with a focus on anglers who specifically fished for Guadalupe Bass. A total of 700 respondents participated in the survey. More than half of respondents were paddlers targeting black bass, and 42% specifically fished for Guadalupe Bass on their trips. An additional 34% of anglers listed black bass species, which included Guadalupe Bass as their preferred species. Similar to previous surveys of Texas river and stream anglers, access was identified as the largest impediment to the future maintenance and improvement of river and stream fishing. Based on 563 surveys used in the economic impact analysis, using IMPLAN (Impact Analysis for Planning) Professional version 2 (Minnesota IMPLAN Group, Minneapolis), an estimated US$74,182,080 in direct angler expenditures was spent on fishing trips to the study region, resulting in a total economic impact (including indirect and induced impacts) of $71,552,492 and 776 full-time jobs. These findings indicate the economic value of river and stream angling to the Texas economy.

<em>Abstract</em>.—Blue catfish <em>Ictalurus furcatus </em>were introduced into North Carolina reservoirs in the mid-1960s and have recently become a popular target for anglers pursuing large catfish. In 2008, the North Carolina Wildlife Resources Commission enacted a maximum size limit for blue catfish at Badin Lake and Lake Norman where only one fish greater than 813 mm could be harvested daily. Surveys indicated that few fish larger than 813 mm were present in either system and that the time to reach the size limit was 12 years in Badin Lake and 20 years in Lake Norman, on average. Although few large fish were present in either system, tournament anglers at Lake Norman kept larger fish in a higher proportion than found in gill-net surveys or harvested during a recent creel survey. Modeling results suggested that the regulation would have little or no impact on increasing the number of large catfish in either population. However, the regulation will protect some rare fish that grow to the maximum size limit and potentially allow recapture opportunities if catch-and-release mortality is low.

Among the partners of the UNESCO Chair The Ocean’s Cultural Heritage are CHAM and IPC (Cape Verde) which defined as essential action the underwater archaeological site inventory of that archipelago. This action started in 2018 as part of the European project CONCHA, that aims to address the different ways that port cities developed around the Atlantic during the early modern era. CONCHA’s surveys were conducted on the island of Santiago, in Ribeira Grande anchorage, in São Francisco (17th century) and in Urânia shipwrecks (1809). The project included the underwater survey, a review of the documentation and of the archaeological materials, recovered from the sites, at the Museum of Archaeology in Praia. Dissemination and training activities were also carried out. This paper systematizes the results of these works.

A survey é um método importante para o campo da Interação Humano-Computador (IHC) por ser de fácil aplicação e possibilitar a coleta de grande quantidade de dados, entretanto, a adaptação de surveys ao contexto do respondente ainda é uma limitação das plataformas on-line. Este trabalho apresenta a plataforma Camaleão, utilizada para criação de surveys on-line com perguntas adaptáveis às respostas dos usuários. A plataforma dispõe de uma interface web para criação e disponibilização de surveys e pode dar suporte para pesquisas de validação de instrumentos psicométricos ou ainda em testes de usabilidade e experiência do usuário (UX) onde este tenha que considerar tópicos específicos de interação.

The purpose of this review is to highlight LiDAR data usage for geomorphic studies and compare to other remote sensing technologies. This review further identifies survey efficiencies and issues that can be problematic in using LiDAR digital elevation models (DEMs) in completing surveys and geomorphic analysis. US Army Corps of Engineers (USACE) geospatial data collection guidance (EM 1110-1-1000) (USACE 2015) aligns with the American Society for Photogrammetry and Remote Sensing Positional Accuracy Standards for Digital Geospatial Data (ASPRS 2014). Geomorphic assessment technologies are rapidly evolving, and LiDAR data collection methods are at the forefront. The FluvialGeomorph (FG) toolbox, developed to support USACE watershed planning, is a recent example of the use of LiDAR high-resolution terrain data to provide a new, efficient approach for rapid watershed assessments (Haring et al. 2020; Haring and Biedenharn 2021). However, there are advantages and disadvantages in using LiDAR data compared to other remote sensing technologies and traditional topographic field survey methods.
