Diante do avanço da produção econômica no Brasil e os consequentes impactos sobre os recursos naturais, a criação do Sistema Nacional de Unidades de Conservação – SNUC, Lei 9.985/2000, determina importantes normatizações e incentivo às medidas de conservação de áreas naturais dos diferentes ecossistemas brasileiros, na busca da difícil compatibilização do desenvolvimento econômico com a proteção à natureza. No estado de Mato Grosso do Sul, município de Aquidauana, as medidas de proteção ambiental são essenciais em virtude das características peculiares do ecossistema Pantanal. Com o objetivo de levantar informações acerca das condições ambientais das Unidades de Conservação no Município de Aquidauana-MS, o estudo propõe uma análise preliminar da evolução do uso da terra e cobertura vegetal das Unidades de Conservação que abrangem a área do Pantanal, referente ao período de 1987 a 2012. Os procedimentos metodológicos adotados consistiram no levantamento bibliográfico, cartográfico, iconográfico e da legislação existente, bem como análise da legislação. Os resultados indicam considerável preocupação em relação ao avanço da pecuária e consequente perda da vegetação nativa, implicando na necessidade urgente de monitoramento e  gestão ambiental para medidas de conservação do Pantanal. Palavras-Chave: Pantanal; Unidades de Conservação; Gestão ambiental AbstractAs a result of the economical advance production in Brazil and the consequent impacts on natural resources, the creation of the Conservation Units National System – SNUC, Law 9.985/2000, determinates important regulations and incentive to the conservation rules for natural areas in the different Brazilian ecosystem, seeking to have the difficult compatibility between economical development and the nature protection. In the state of Mato Grosso do Sul, municipality of Aquidauana, the environmental protection measures are essential due to the singular characteristics of the Pantanal ecosystem. Aiming to collect information about the environmental conditions of the Conservation Units in the municipality of Aquidauana-MS, the study proposes a preliminary analysis of the evolution of the land use and vegetal coverage in the Conservation Units that include the wetlands of Pantanal, referring to the periods from 1987 to 2012. The methodological procedures adopted consisted of literature, cartographical and iconographical survey as well as the existing legislation study. The results indicate considerable concern about the cattle breeding rise and eventual loss of the native vegetation, implying the urgent necessity of monitoring and environmental management for Pantanal conservation measures. Keywords: Pantanal; Conservation Units; Environmental Management.

Modern manufacturing industries are increasingly faced with international competition and fluctuating market conditions in the age of globalization. In striving to remain competitive, manufacturing industries must deliver products to customer at the lowest cost, at the best quality and in the minimum lead time. As a result, it becomes mandatory to design and implement the advance production planning and scheduling system that supports shorter product cycles despite more complex and specialized manufacturing processes. The advance production planning and scheduling system provides the leaner production strategies and real time information throughout the industry. This paper presents an appropriate Advance Production Planning and Scheduling Software System for a batch production aerospace manufacturing industry. The Software system receive the customer‘s order and perform material requirement planning using software. The software system sends procurement requisition to the procurement department for the materials which is not available in the store for manufacturing of parts. It issues release order to the store section for the issuance of material to the manufacturing shops. It also issues weekly and daily plan with production schedule to the manufacturing shops. It also issues work orders to the production shops for the manufacturing and assembly of the parts. On the completion of the product assembly, proper closing of the work orders has to be done and product may deliver to the warehouse for further handing over to the customers. In case of modification of order by the customer, the Software System will automatically update the relevant data.

Temperature and photoperiod are known as the main stimuli of seasonal reproduction in fish. Turbot (Scophthalmus maximus) is a spring spawning teleost fish species with a promising aquaculture potential and high market value. This study was conducted to assess the effect of photoperiod manipulation on spawning time and spawning performance of turbot. A total of 28 mature turbots from the Black Sea population were subjected to manipulated photoperiod (a photoperiod regime that fish would naturally receive three months later) and natural photoperiod for almost a year. While the fish exposed to natural photoperiod spawned in May, the fish exposed to manipulated photoperiod spawned almost three months earlier compared to the natural photoperiod group. Reproductive and hatchery performance of the manipulated photoperiod and natural photoperiod groups were similar. It can be emphasized that photoperiod play an important role in accelerating maturation and spawning. The findings of this study could be implemented in the turbot aquaculture industry to advance production.
