abstract: This research examines the use of innovative mechanisms for encouragement of citizen participation in the governance, policy, and decision making processes using case studies of Washington, DC, the United States and Seoul, South Korea for comparison. The research illustrates ways of encouraging development of citizen participation using innovative mechanisms through comparative study. This research used a comparative case study of the two cities which focuses on how the two governments apply ICTs and foster citizen participation, what similarities and differences there are between the two city governments' performance and practices, and what may cause these similarities and differences. For the research, websites and citizen participation practices of Washington, DC and Seoul using innovative technologies - Citizen Summit and Seoul Oasis - are reviewed and compared using the categories of general capacity, actor, legal aspect, management, and evaluation. As capitals of the United States and South Korea, Washington, DC and Seoul lead the encouragement of citizen participation, and the two cities' specific practices are recognized as exemplary. The findings describe encouragement of citizen participation using innovative technologies in governance, policy, and decision making processes of Washington, DC and Seoul as well as similarities and differences. Both cities commonly use Government 2.0. Through Government 2.0, citizens can participate and influence the results and effects of policy. Also, governments secure transparency, legitimacy, and efficiency through direct communication with citizens. The study illustrates how citizen participation using innovative technologies can support civic engagement in local government. Strong leadership of the mayor is a common driving force of the two cities in initiating and implementing the Citizen Summit and Seoul Oasis. Different contexts of the two cities influence ways to initiate and utilize innovative technologies. Washington, DC implemented a practice combining public meeting and small group discussion using innovative technologies. On the other hand, Seoul initiated a new citizen participation practice based on the Internet. The results of the research show that innovative mechanisms allow adopting new government-citizen relationships in both cities. / Dissertation/Thesis / Ph.D. Public Administration 2011

A qualidade dos produtos e sua apresentação ao consumidor são as características mais marcantes nessa mudança. Hortaliças minimamente processadas são aquelas que foram fisicamente alteradas, mas que permanecem no estado fresco. As sucessivas manipulações na produção aumentam as possibilidades de contaminação microbiológica desses produtos. O objetivo deste trabalho foi avaliar a contaminação microbiológica por Salmonella sp. e coliformes a 45°C em dois elos da cadeia produtiva de couve minimamente processada para identificação do ponto crítico de contaminação. Foram coletadas amostras de couve na Agroindústria Machadinho, Brazlândia-DF, em todas as etapas do processo produtivo dentro da agroindústria, além de amostras coletadas em supermercados de Brasília-DF. Foi detectada contaminação por coliformes a 45°C apenas em amostras adquiridas nos supermercados. Verificou-se a necessidade de uma maior integração entre Agroindústria e supermercados, bem como a necessidade de treinamento de gerentes e manipuladores, e a aquisição de equipamentos objetivando a manutenção da qualidade ao longo da cadeia. _____________________________________________________________________________ ABSTRACT / The trade of vegetable crops has changed substantially in the last years. Quality and presentation of the products are the μost iμportant facts in this change. Miniμally processed vegetables are those that have been physically changed but have kept their fresh condition. The successive μanipulation increases the chance of μicrobiological contaμination of the products. The aiμ of this research was to evaluate the μicrobiological contaμination by Salμonella sp. and fecal coliforμes at 45°C in two segμents of the μiniμally processed Chinese kale to identify critical points. Saμples of μiniμally processed Chinese kale were colected froμ Agroindústria Machadinho, Brazlândia−DF, and froμ superμarkets in Brasilia DF. It was detected contaμination by fecal coliforμes at 45ºC in the saμples froμ the superμarkets. It was observed the need of a higher integration between the agroindustry and the superμarkets. It is also necessary training of μanagers and staff, as well as the acquisition of equipμents aiμing quality μaintenance in this supply chain.

Durante o processo de desenvolvimento das acerolas o conteúdo de vitamina C e de polifenóis solúveis totais (PST) diminuiu resultando em um declínio da atividade antioxidante dos frutos Apesar da redução dos PST o conteúdo de flavonóides amarelos e antocianinas totais mostraram um aumento evidente com o amadurecimento o que pode estar associado à mudança de cor e propriedades antioxidantes nutricionais da acerola Enquanto no sapoti o conteúdo dos compostos antioxidantes diminuiu significativamente ao longo do desenvolvimento contribuindo para uma redução da AAT resultante principalmente do declínio do conteúdo dos fenólicos flavonóides amarelos e polifenóis totais pois o sapoti não é considerado uma boa fonte de vitamina C A atividade das enzimas antioxidantes dismutase do superóxido (SOD) catalase (CAT) e peroxidase do ascorbato (APX) diminuiu ao longo do amadurecimento dos frutos tropicais estudados o que contribuiu para um aumento do estresse oxidativo evidenciado pelo aumento da peroxidação de lipídeos sendo, portanto necessário para facilitar muitas das mudanças relacionadas com a maturação O amadurecimento das espécies tropicais estudadas foi acompanhado por um aumento do estresse oxidativo e peroxidativo o qual pode contribuir para as alterações observadas na qualidade pós-colheita dos frutos e para um declínio em seu potencial antioxidante.
