In this thesis, three key issues that restrict networks from scaling up so as to be able to cope with the rapid increase in traffic are investigated and series of approaches are proposed and tested for overcoming them. Firstly, scalability limitations owing to the use of a broadcast mechanism in one collision domain are discussed. To address this matter, servers under software-defined network architectures for eliminating discovery messages (SSED) are designed in this thesis and a backbone of floodless packets in an SDN LAN network is introduced. SSED has an innovative mechanism for defining the relationship between the servers and SDN architecture. Experimental results, after constructing and applying an authentic testbed, verify that SSED has the ability to improve upon the scalability of the traditional mechanism in terms of the number of switches and hosts. This is achieved by removing broadcast packets from the data and control planes as well as offering a better response time. Secondly, the scalability restrictions from using routers and the default gateway mechanism are explained. In this thesis, multiple distributed subnets using SDN architecture and servers to eliminate router devices and the default gateway mechanism (MSSERD) are introduced, designed and implemented as the general backbone for scalable multiple LAN-based networks. MSSERD's proposed components handle address resolution protocol (ARP) discovery packets and general IP packets across different subnets. Moreover, a general view of the network is provided through a multi-subnets discovery protocol (MDP). A 23 computers testbed is built and the results verify that MSSERD scales up the number of subnets more than traditional approaches, enhances the efficiency significantly, especially with high load, improves performance 2.3 times over legacy mechanisms and substantially reduces complexity. Finally, most of the available distributed-based architectures for different domains are reviewed and the aggregation discovery mechanism analysed to establish their impact on network scalability. Subsequently, a general distributed-centralised architecture with open-level control plane (OLC) architecture and a dynamic discovery hierarchical protocol (DHP) is introduced to provide better scalability in an SDN network. OLC can scale up the network with high performance even during high traffic.

The centralized management that exist currently hampers a ready solution for small problems that accrue becoming major structural problems that directly and indirectly impact in the student‟s pedagogical development. The community participation in school defense is old, although it‟s very limited. Currently School Units don‟t have financial management autonomy and the little money that they receive is passed to the APM- School parents and teachers association who is a non-profit legal entity, unlinked to the school and not embodies the School Unit. The APM is an instrument used by the legislature to fulfill that prescribes the LDB, Brazilian Federal law for education guidelines and bases about democratic management at public schools. The problem is that APM, instead of making the social control of the School Unit, manage their resources and thereby lost his exemption to supervise the administrative acts, since it is also a practitioner of these same acts. Although cited in many works, the issue of school units "autonomy", to be obtained as a result of actions outlined during the planning moments can be considered as a strong absence. Our research looks for alternatives ways for schools financial resources management that improve results in terms of expertise, general culture, social training and at the same time enable to Public Manager and team, responsible for school direction, a fast, efficient and accurate tool for action / As escolas públicas de brasileiras vivenciam uma fase crítica de deterioração das suas instalações físicas e de seus equipamentos pedagógicos. A centralização administrativa atualmente existente dificulta a pronta solução de pequenos problemas que, ao acumularem-se, transformam-se em grandes problemas estruturais que influem direta e indiretamente no aproveitamento pedagógico dos alunos. A defesa da participação da comunidade na escola, ainda que muito limitada, é antiga. Atualmente as Unidades Escolares não possuem autonomia na gestão financeira e o pouco recurso que recebem é repassado para a APM - Associação de Pais e Mestres que é uma entidade jurídica sem fins lucrativos, desvinculada da escola e não personifica a Unidade Escolar. A APM é o instrumento utilizado pelo legislador para cumprir o que prescreve a LDB-Lei de Diretrizes e Bases da Educação no tocante à gestão democrática do ensino público. O problema é que a APM, invés de fazer o controle social da Unidade Escolar, passou a gerir os seus recursos e com isso perdeu a isenção de fiscalizar os atos administrativos, uma vez que também é praticante destes mesmos atos. Apesar de citada em muitos trabalhos, a questão da autonomia das unidades escolares, a ser obtida como resultante das ações delineadas durante os momentos de planejamento pode ser considerada como uma significativa ausência. A nossa pesquisa procura alternativas na forma de gestão dos recursos financeiros das escolas que melhorem o resultado em termos de conhecimentos específicos, cultura geral, formação social e ao mesmo tempo possibilite ao Gestor Público e sua Equipe, responsáveis pela direção da Escola, uma ferramenta administrativa de ação rápida, eficiente e precisa

The importance of franchising in Brazil as a supplier of products and services and its social significance by creating jobs and collecting taxes makes the franchising chains administration a very important issue, justifying all the efforts seeking for improvement in this area. The characteristics of this organizational model bring specific challenges to managers, mainly the integration of the chain components: franchisers, franchisees and chain customer. This dissertation has the following main objectives: to show why the use of heterogeneous and non-integrated systems by franchising chains can increase the management problems of these kind of organizations; to define an architecture of a unique, centralized and integrated system to franchising chains; and to propose its adoption by managers of franchising chains to mitigate or even eliminate several identified administration problems. The results of a research about the administration system adopted by educational franchising chains in Brazil are presented to evidence its integration stage. Finally, a case study shows the perception of the benefits followed by the adoption of a unique, centralized and integrated management system by an educational franchising chain. The research results show that a great number of educational franchising chains in Brazil still adopt heterogeneous and non-integrated systems on the chain units. This kind of solution makes the exchange of data, information and knowledge difficult, reducing the collaboration between the chain members and confusing the chain administration. This study proposes a systems architecture that ensures the integration between the chain elements, becoming an important management tool to educational franchising chains, facilitating the agility and increasing the competitive capacity for these organizations. This is the perception of the executive managers of the franchising chain case study that adopted a unique, centralized and integrated system and had an improved administration capacity / O modelo de organização empresarial em rede, particularmente redes de franquias, vem crescendo a taxas bastante superiores à média da economia. A importância do setor de franquias no Brasil como fornecedor de produtos e serviços e o seu peso social como gerador de empregos e na arrecadação de impostos tornam a administração das redes de franquias um elemento relevante dentro do cenário econômico nacional, justificando as iniciativas de aprimoramento da gestão de redes de franquias. As características deste modelo organizacional impõem desafios específicos aos administradores, principalmente quanto ao grau de integração entre os elementos da rede, quais sejam franqueadores, franqueados e clientes finais. Esta dissertação tem como principais objetivos: mostrar porque a utilização de sistemas não integrados e heterogêneos tradicionalmente utilizados pelas redes de franquias pode potencializar as dificuldades de administração destas organizações; definir a arquitetura de um sistema único, centralizado e integrado para a gestão de redes de franquias; e propor a sua adoção por redes de franquias para mitigar ou até mesmo eliminar diversos dos problemas de gestão identificados. À guisa de ilustração, são discriminados os resultados de uma pesquisa sobre os sistemas de gestão utilizados por redes de franquias do segmento educacional no Brasil, com o fito de evidenciar seu estágio de integração e centralização. Por fim, um estudo de caso de uma rede de franquias educacional que já adota um sistema único, centralizado e integrado de gestão, mostra a percepção dos benefícios encontrados na adoção deste tipo inovador de solução. Os resultados da pesquisa mostram que a grande maioria das redes de franquias do segmento educacional adota, em suas unidades, sistemas de gestão heterogêneos e isolados entre si e em relação ao sistema do franqueador. Este tipo de solução dificulta a troca de dados, informações e conhecimento, diminuindo a possibilidade de colaboração entre os integrantes da rede e dificultando a administração da organização. A arquitetura de sistemas proposta neste estudo permite a integração dos elementos de uma rede, podendo constituir-se em uma importante ferramenta na gestão de redes de franquias, apoiando a agilidade e a competitividade destas organizações. Esta é a percepção dos executivos da rede de franquias do estudo de caso, que teve sua administração facilitada e aperfeiçoada a partir da adoção de um sistema único, centralizado e integrado de gestão

Since Taiwan put the NHI into practice, Drug Price Black-Hole of the NHI has estimated about 20 billion every year under the fee-for-service payment system (FFS) and pricing drug with brand. Therefore, we collect the papers and some cases to discuss the situation of the Drug Supply Chain in Taiwan. We would like to understand how to descrease the drug cost in purchasing and distributing by this paper. This paper makes use of Value Chain, Diamond Theory, New Value Curve to analyze the Drug Supply Chain in Taiwan and proposes the model and process to direct the industry how to developing the Drug Supply Chain by certralized management. The Drug Supply Chain of certralized management can provide some benefit as following: 1. Purchase jointly to reach economies of scale 2. Simplify the reporting process 3. Effectively use the information of the drugs 4. Utilize the distributed process by jointly delivery 5. Help the separation profession of pharmacy from medicine to implement Besides, this paper proposes the initial plan about the Drug Supply Chain of certralized management as following: 1.Begin with governmental hospitals. 2. Select large amount of the drugs of NHI. 3. Provide flexible frequency of distribution. 4. Intergrate the information flow and cash flow. 5. Bureau of National Health Insurance (BNHI) supports the Internet Servie provider (ISP) to build the platform of the Drug Supply Chain. Our main goal is to adapt this kind of model to help NHI overcome financial crisis by jointly purchasing and distributing, simplifying the process of reporting and help the separation profession of pharmacy from medicine.

The purpose of this dissertation was to identify factors that contribute to the sustainability of rural water supply facilities (WSFs). Twenty-four interviews were conducted: 16 from rural communities and 8 from water supply agencies. Key findings are that in order to achieve sustainability of WSFs, there is need to ensure that (1) there is an effective community organisation; (2) communities have the ability to operate and maintain WSFs; (3) communities are able to raise adequate user fees for purchasing spare parts; and (4) that there is a strong backup support at the district level to carry out major repairs. Major threats to the sustainability of WSFs include high poverty levels in communities, weak institutional framework and inability of communities to handle major breakdowns. / Social Work / M.A. (Social Work)
