O extrativismo vegetal, baseado na exploração sustentável dos produtos florestais não madeireiros é uma das alternativas mais consistentes ecologicamente, no que tange a Conservação da biodiversidade e cobertura natural da Floresta Amazônica. Mas, há problemas sistêmicos que não têm deixado este segmento desenvolver-se de forma satisfatória. O vazamento da economia regional dos produtos extrativistas da Amazônia é uma variável que contribui para o baixo nível de desenvolvimento social e econômico da região. É imperativo que sejam realizadas análises econômicas sobre as possibilidades desse novo modelo A solução provisória para esta área foi estabelecida em 1841, com a definição do espaço entre os rios Oiapoque e Araguari como “Área do Contestado”. Ficou definido então, que a gestão da referida área seria feita de forma compartilhada entre os dois Países. A questão da disputa entre Brasil e França pelas terras do Amapá, só se resolveu definitivamente com a intermediação do presidente suíço Walter Hauser, que em 1o de dezembro de 1900, através do protocolo conhecido como “Laudo Suíço”, concedeu a referida área ao Brasil. de desenvolvimento, apoiado nas bases de um capitalismo contemporâneo, que tem procurado aprimorar os mecanismos econômicos de inclusão social de variáveis ambientais como elementos endógenos do sistema produtivo na Amazônia. O Amapá é o estado brasileiro mais preservado (97% de sua cobertura florestal original) e possui 72% do território como áreas protegidas. Este trabalho pretende identificar o nível de contribuição que os produtos não-madeireiros, extraídos nas florestas por populações tradicionais têm na economia do Amapá. Como método central de análise, foi utilizado o modelo de matriz insumo-produto desenvolvido por Wassily Leontief. Este procedimento analítico tem relevante destaque como instrumento prático de análise e planejamento econômico. Além das análises de programação do crescimento econômico setorial, é adequado para estimar, mediante os efeitos multiplicadores, os impactos do crescimento econômico na produção trabalho e renda setorial de toda a economia. O objeto central do trabalho são as análises estruturais dos arranjos produtivos locais dos produtos florestais não-madeireiros do estado do Amapá, em níveis regional e local. O método desenvolvido pelo Francisco de Assis Costa (Contas Sociais Ascendentes Alfa - CS_) foi usado na construção das matrízes, tendo como base os procedimentos analíticos ascendentes de agregação progressiva dos dados locais O setor extrativista dos produtos florestais não -madeireiros do estado do Amapá, com um PIB de R$ 204 milhões no ano de 2009 tem uma participação pequena, com somente 3,07% das riquezas produzidas no estado. Todavia, quando é observado que 86,77% do valor total do PIB (6,65 bilhões de reais) é decorrente de atividades do Setor Terciário e que todo o Setor Produtivo (Primário e Secundário), tem participação de apenas 13,24%, conclui-se que o valor da produção dos produtos florestais não-madeireiros é bem significativo no estado do Amapá.

The purpose of this paper is to analyze the integration of environmental issues in the context of manufacturing function/production (or operations), which is considered the organizational area that should lead corporate environmental management. We present a background on the greening of the manufacturing area, especially in terms of product development, process, quality management and logistics. Four case studies of Brazilian companies are presented as part of the study, and it is found that the maturity level of these companies' environmental management tends to follow the degree to which the environment has been inserted into subareas of production, especially in the process of product development. However, difficulties encountered in greening a company's logistics activities are also recognized in most cases. It is concluded that companies can overcome this challenge by adopting new concepts of green supply chain management. The notes highlight the observed distance between arguments in the international literature and the reality of Brazilian companies on the greening of manufacturing aspects.

The purpose of this study is to describe the development of a model to predict the digestible lysine requirements of broilers using the factorial approach, and to evaluate the model using as reference the model presented in Brazilian Tables for Poultry and Swine. The model partitions the requirement for maintenance and growth for feather-free body protein and feather protein, in which the inputs are body and feather protein weight and the daily rates of protein deposition in the feather-free body and feathers. The parameters that express the lysine requirement for maintenance were obtained in metabolism trials with roosters, and those for the efficiency of lysine utilization in experiments with broilers from 1 to 42 d. Based on these results the model proposed was: Lys (mg/d) = [(151xBP(m)(-0.27)xBP(t)) + (0.01xP(t)x18)] + [(75xBPD/0.77) + (18xFPD/0.77)], where Lys = digestible lysine requirement (mg/d), BPm=body protein weight at maturity (kg), BPt=body protein weight at time t (kg), FPt=feather protein weight at time t (kg), BPD=body protein deposition (g/d), FPD = feather protein deposition (g/d). The model yields sensible predictions of the digestible lysine requirements of broilers of different strains and ages growing at their potential, and suggests a lower lysine requirement after 27 d than does the Brazilian model. The proposed model is the first step in the development of a simulation model that predicts the food intake of a broiler and hence the dietary amino acid content that would optimise performance.

Due to the competitive advantages derived from appropriate logistical operations, and the high costs associated with it, companies began to consider academic studies conducted in this area in order to optimize its processes and satisfy its customers. Logistics, an essential part of supply chain management, is also responsible for all internal movements within a manufacturing facility, ensuring that production lines are properly stocked. This category is called In-Plant Logistics and the target of this case study. It was observed that the following company, which belongs to soap powder manufacturer business, faces numerous stops of its production lines. For that reason, it was proposed to create a staging area, which will ensure greater visibility of the production plan, avoiding replannings, besides relieving the work of overloaded departments

Current studies indicate a need to integrate environmental management with manufacturing strategy, including topics like cross-functional integration, environmental impact, and waste reduction. Nevertheless, such studies are relatively rare, existing still a need for research in specific regional contexts. At the same time, the results found are not unanimous. Due to these gaps, the objective of this article is to analyze if environmental management can be considered a new competitive priority for manufacturing enterprises located in Brazil. A cross-sectional survey was conducted with Brazilian companies certified by ISO 14001. Sixty-five valid questionnaires were analyzed through Structural Equation Modelling (SEM). The first conclusion is that environmental management presents a preventive approach in the sample analyzed, focused on eco-efficiency, what potentially do not to create a competitive advantage. This preventive approach inhibits environmental management from being regarded as a new competitive manufacturing priority, in the full sense as defined by the literature. Another important result is that environmental management, although following a preventive focus, may influence positively the four manufacturing priorities: cost, quality, flexibility and delivery.

O objetivo do artigo é apresentar um quadro de referência de conceitos da Gestão da Sustentabilidade na Cadeia de Suprimentos (GSCS) para auxiliar pesquisas futuras na tentativa de integração intra e interorganizacional fundamentada em aspectos da sustentabilidade. Trata-se de um artigo teórico, cujo procedimento metodológico adotado foi o desk research em periódicos da área de gestão e operações, realizado em duas etapas. Na primeira, buscou-se visualizar os estudos da temática em seis importantes periódicos internacionais da área, totalizando 53 artigos entre 1954 e 2009. Esta etapa gerou uma evolução da temática, contribuindo para apontar tendências. Na segunda, foram revisados seis periódicos nacionais da área de administração. Selecionaram-se 11 artigos, publicados entre 1961 e 2009, resultando em um panorama da temática no contexto acadêmico brasileiro. O conceito de GSCS apareceu apenas em 2007, o que mostra a atualidade do tema, embora este seja a junção de temáticas anteriormente estudadas.

[EN] Background: Spain has gone from a surplus to a shortage of medical doctors in very few years. Medium and long-term planning for health professionals has become a high priority for health authorities. Methods: We created a supply and demand/need simulation model for 43 medical specialties using system dynamics. The model includes demographic, education and labour market variables. Several scenarios were defined. Variables controllable by health planners can be set as parameters to simulate different scenarios. The model calculates the supply and the deficit or surplus. Experts set the ratio of specialists needed per 1000 inhabitants with a Delphi method. Results: In the scenario of the baseline model with moderate population growth, the deficit of medical specialists will grow from 2% at present (2800 specialists) to 14.3% in 2025 (almost 21 000). The specialties with the greatest medium-term shortages are Anesthesiology, Orthopedic and Traumatic Surgery, Pediatric Surgery, Plastic Aesthetic and Reparatory Surgery, Family and Community Medicine, Pediatrics, Radiology, and Urology. Conclusions: The model suggests the need to increase the number of students admitted to medical school. Training itineraries should be redesigned to facilitate mobility among specialties. In the meantime, the need to make more flexible the supply in the short term is being filled by the immigration of physicians from new members of the European Union and from Latin America.
