    Estágio com Relatório em Urbanismo Sustentável e Ordenamento do TerritórioThe following internship report has the objective of presenting the work that has been done during 5 months within the scope of the non-teaching component of the master's course in Sustainable Urbanism and Spatial Planning, taught at the Faculty of Science and Technology (FCT) at NOVA University in Lisbon. Over the course of the entire master’s from September 2019 until September 2021, I have developed a special interest in climate change adaptation. The objective of the internship consisted out of assisting and co-constructing the development of a project related to climate adaptation and to learn how to work in a team both on the national and international level. During the time of the internship, I participated in the EIT Climate-KIC funded project 'MEDCLIV', which envisages to apply experimental and participatory approaches to develop and share solutions and co-built ways of climate adaptation and mitigation within the vine and wine value chain. Most of the activities realized are connected to the development of the platform called Vineas, a co-constructed platform for climate adaptation in the vine and wine sector made by all the participating countries in the Mediterranean. As the platform Vineas is focussed on identifying possible climate adaptation and miti-gation options, the question became pertinent to what extent different wine regions of Portu-gal (IGP’s) were actually affected by different climate risks. Therefore, a research was set up as part of this internship report to identify the potential climate risk for different parts of Conti-nental Portugal for 5 different hazards. The methodology of this research follows the concep-tual framework of the Fifth Assessment Report (AR5) of the IPCC, which states that the total climate risk is constituted through the interplay of the hazards, and the potential exposure and vulnerability. The internship report is ended by a short reflection on the research and the in-ternship followed, which will result in some recommendations for further development strat-egies for the vine and wine sector and the platform Vineas.O seguinte relatório de estágio tem como objetivo apresentar o trabalho desenvolvido durante 5 meses, no âmbito da componente não letiva do curso de mestrado em Urbanismo Sustentável e Ordenamento do Território, ministrado na Faculdade de Ciências e Tecnologia (FCT) da Universidade NOVA em Lisboa. Ao longo do mestrado, de setembro de 2019 até setembro de 2021, desenvolvi um interesse especial na adaptação às alterações climáticas. O objetivo do estágio consistiu em auxiliar e co-construir o desenvolvimento de um projeto rel-acionado com a adaptação climática e aprender a trabalhar em equipa a nível nacional e in-ternacional. Durante o período do estágio, participei no projeto financiado pelo EIT Climate-KIC de nominado MEDCLIV, que visa aplicar abordagens experimentais e participativas para desen volver e compartilhar soluções e formas co-construídas de adaptação e mitigação do clima na cadeia de valor da videira. Uma vez que a plataforma Vineas está focada na identificação de possíveis opções de adaptação e mitigação do clima, a questão tornou-se pertinente em que medida as diferentes regiões vitivinícolas de Portugal (IGP’s) foram efetivamente afetadas por diferentes riscos climáticos. Assim, foi realizada uma pesquisa no âmbito deste relatório de estágio para iden-tificar estes riscos climáticos para diferentes regiões de Portugal Continental. A metodologia desta pesquisa segue o arcabouço conceitual do Quinto Relatório de Avaliação (AR5) do IPCC, que afirma que o risco climático total é constituído pela interação dos perigos, a exposição potencial e vulnerabilidade. O relatório de estágio é finalizado com uma breve reflexão sobre a pesquisa e o estágio realizado, que resultará em algumas recomendações para o futuro

    Indonesia is in an era of globalization, it can be seen by the era of technology that introduced the virtual world (cyberspace, virtual world) through internet networks, communication with electronic media without paper. The development of electronic signature technology has been implemented in Indonesia. The existence of electronic signatures has begun to replace conventional signatures in several places on the grounds of using technology to make it easier. The ІTE Act already guarantees electronic signatures. GMS can be held using electoral media. However, the GMS with electronic media must be approved and signed by the GMS participants. In the notary deed, the minutes of the GMS are included in the release deed. Preparation of a notary deed of the GMS minutes using an electronic system must be signed by all GMS participants. Participants who attend the meeting via video conference can use the signature using the electronic system. Legal Issues in this Research There are unclear norms related to signatures which are described in the Law on Notary Position. This research is normative law research. From the results of the research using the above method, the author obtains answers to the problems regarding the Law of Signing Notary Deeds Using Electronic Signatures.

    Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementNowadays, the use of creativity in business has been increasing drastically because it is important for the market to come up with new ways to find answers to the problems proposed by the users. There are several different creativity techniques that can be used in different contexts. One of the most important techniques is the SCAMPER technique, which is based in reorganizing, modifying, adding and eliminating information. An automated system will provide answers and solutions to creativity problems and contribute to minimize the cost of innovation in the companies. For that reason businesses will be able and willing to continue to use creativity when innovating. The aim of this thesis is therefore to design an architecture system for a creative information system based on an automated system that relies on the SCAMPER creativity technique

    Doutoramento em Arquitetura Paisagista - Instituto Superior de AgronomiaOne of the most complex issues that modern society is facing is landscape transformation, its fragmentation and ecological simplification, resulting in loss of biodiversity and a decline in ecosystems’ quality. Recently, the concept and establishment of Ecological Networks (EN) have been seen as a solution towards nature conservation strategies targeting biodiversity and ecological connectivity, (re)focusing on the ecosystem approach and the “continuum naturale”. The research in this dissertation aims to clarify the potential of EN in the context of landscape planning and its importance and function within the Green Infrastructure (GI) concept, emerging from EU Biodiversity Strategy to 2020, as a fundamental strategically connected infrastructure of abiotic and biotic systems underlying the provision of multiple functions valuable to society. It also addresses the lack of mapping at the national level of ecological systems. The main research objectives are: 1) To develop a methodology to map the National Ecological Network (NEN) for mainland Portugal and 2) To develop a Land Morphology (LM) mapping method at the national level. LM classifies landforms according to their hydrological position in the watershed and represents a helpful evaluation tool for modelling natural systems. This thesis contributes to the understanding of: i) the NEN as a spatial network that defines areas of existing and potential ecological connectivity at various scales which provides the physical and biological conditions necessary to maintain or restore landscape’ ecological functions; ii) the importance of NEN as an ecologically based tool towards a more sustainable landscape planning, strengthening the notions of connectivity and multi-functionality of landscape; iii) the morphological approach to map Portuguese landforms as valuable tool to assist policy makers and planners in taking decisions based on a more thorough analysis of land value and its ecological functions; and iv) Mapping the wet system at national level may have an impact on clarifying concepts related to water resources and can be used as a preliminary delimitation of floodplains and potential flood risk areasN/

    Research and innovation are two pillars that come together when universities are at stake. The expansion of the frontiers of human knowledge, in all areas and disciplines, is an irrefutable commitment of higher education institutions. Together with public and private entities, they are also committed to promoting knowledge transfer to society and the economy, in the form of new ideas, new products and new processes. Universities are supposed to transform ideas into value for society. To achieve these goals, higher education institutions have to assure their human resources are highly qualified, that they have an adequate atmosphere, that research is of high quality, and finally that adequate interactions take place. At UMinho we have a clear strategy to be an open and permanent space for knowledge production and furtherance of nationally and internationally relevant innovation across different social and economic sectors. For many years, UMinho has adopted the principles of open access and open science. We aim at carrying out our scientific activity and the dissemination of the corresponding results transparently and collaboratively; this implies that researchers, citizens, policymakers, state agencies, companies, and third sector organizations work in close cooperation facing research and innovation processes. We believe this is the shorter way to trigger smart and sustainable growth and qualified job creation. At UMinho, we encourage the coupling between research and education. Our goal is to expand research opportunities and to give our students occasions to experience vibrant research environments, ensuring that learning goes beyond the “common” routines. Joining research and learning processes provides both undergraduate and postgraduate students with opportunities to own their learning process. We believe that research experience has a role to play in improving students’ motivation for learning, in the pursuit of their interests. Doing better science occurs when we make it both more sensitive to the needs of society and also more efficient in what concerns the allocated resources. It is also a question of accountability. This is fundamental for reinforcing society awareness about our contributions to human and social development. Following the 2018 publication, we present here the 2019 edition of Research and Innovation, a series that draws on the outcomes of the activity of the UMinho research and innovation ecosystem. This comprehensive volume gives particular emphasis to the Research Units outcomes, namely in terms of funding, research projects, papers, and the most important achievements; the activity of the Interface Units and Collaborative Laboratories in which UMinho participates is also reported, through their activities and institutional projects, making evident their importance for the continuous growth of our Institution, our region, and our country.

    365870/13 (depósito legal)No âmbito das actividades de I&DT da empresa Sinergeo, Lda., o projecto PROSPEG (nº 11480), dedicado à investigação em prospecção e pesquisa e pegmatitos graníticos, co-financiado pelo “ON.2 – O Novo Norte e QREN através do fundo Europeu de Desenvolvimento Regional (FEDER), resultou de uma co-promocão com a Universidade do Minho. É objectivo geral do projecto o desenvolvimento de programas de prospeccão e pesquisa de pegmatitos no território português, utilizando como via fundamental para a primeira aproximação a áreas de pesquisa, metodologias de análise distanciada e deteccão remota. Justifica-se a investigação neste domínio pelas dificuldades de implementação de outros métodos geofísicos e geoquímicos, dado o deficiente contraste entre pegmatito e encaixante. Por outro lado, a inscrição da análise distanciada e deteccão remota em programas de prospecção estratégica de pegmatitos, também se afigura vantajosa em termos da relação custo/beneficio e da extensão e densidade da cobertura que permite. Em estádio estratégico as acções de prospecção incidiram sobre um conjunto de áreas, reconhecida ou hipoteticamente férteis no que respeita a ocorrência de pegmatitos com interesse económico. Essas áreas podem ser encaradas como compartimentos da Província Pegmatítica Varisca do Norte e Centro de Portugal onde ocorrem pegmatitos com uma grande diversidade intrínseca, estrutural, morfométrica, mineralógica e económica, representando simultaneamente diferentes níveis estruturais de colocação e de exumação dos conjuntos e corpos pegmatíticos individuais. Os suportes escolhidos para a análise distanciada foram imagens multiespectrais dos sensores LANDSAT e SPOT e ainda imagens disponibilizadas pelo Google Earth Pro. Estas foram submetidas a tratamento, através de processamentos digitais que incluíram a ampliação de contraste, a combinação RGB de bandas espectrais, a análise em componentes principais e a classificação Maxver de imagens. A conjugação destas técnicas permitiu tornar mais evidentes padrões geométricos, cromáticos, texturais e espectrais da expressão superficial de pegmatitos e seus indicadores de prospecção. Combinando aqueles procedimentos de processamento com indicações relativas a faixas e maciços produtivos, provenientes da análise sobre a distribuição regional de corpos nas áreas consideradas e aproveitando critérios empíricos geológico-estruturais e geomorfológicos, foi possível seleccionar um conjunto de áreas mais restritas sobre as quais se desenvolveram trabalhos de investigação geológica. Estes compreenderam numa primeira fase cartografia geológica a escalas 1:5000, como via para a identificação de sectores com índices pegmatíticos em situação potencialmente económica, a investigar mediante sondagens. A partir destes levantamentos, alguns guias estruturais e litológicos condicionantes da presença de pegmatitos em contexto intra-granítico, também puderam ser discriminados. A direccão N30E, tardi-Varisca, parece condicionar de forma estrita a instalação dos corpos com maior volume no Norte e Centro de Portugal. Por outro lado também se nota que a distribuição dos pegmatitos revela um caracter coincidente com sectores de maior diversificação e heterogeneidade litológica, reconhecendo-se as seguintes fácies tendentes para pegmatitos: leucogranitos com grão fino com biotites nodulares, amarelecidos por lixiviação com influência supergénica; fácies com tendência leucocrata com diferenciações difusas pegmatíticas; fácies microporfiróides com evidências de fluxo; fácies miarolíticas pontuadas por bolhas pegmatíticas; leucogranitos portadores de cordierite e granada; biotititos estabelecidos na superfície de contacto entre fácies graníticas e granitos porfiróides enrubescidos por hematitizacão hidrotermal a supergénica. O programa de prospeccão pontual com sondagens levado a cabo foi em alguns casos bem-sucedido, tendo--se chegado a intersectar em profundidade uma bolsada pegmatítica com dimensão apreciável. Noutros casos foi possível delimitar em profundidade o desenvolvimento de corpos conhecidos, sujeitos a exploração no passado, e aí aumentar o quantitativo de reservas potenciais. Nos casos em que se recorreu a métodos destrutivos de furação, adoptou-se de forma inovadora, como forma de obter correspondentes colunas de sondagem, a filmagem de furos combinada com a análise mineralométrica de cuttings. Como subsídios do programa de sondagens também se refere a optimizacão de modelos geométricos e conceptuais de pegmatitos, os quais podem representar conjecturas paradigmáticas passíveis de extrapolação aos campos portugueses e desta forma apoiar subsequentes programas de prospecção pontual. Também a partir dos logs de sondagem, aqui encarados como colunas graníticas produtivas em pegmatitos, foi possível inferir sobre tendências de fraccionação, segregação e fluxo, capazes de fomentar o aparecimento de magmas leucograníticos transicionais e pegmatíticos, que podem posteriormente evoluir in situ ou ser mobilizados e libertados para corredores estruturais. As tendências parecem ser em alguns casos oscilatórias com ritmos bem definidos na organização das cúpulas, e do ponto de vista da detecção remota as fácies resultantes são à partida perceptíveis, na medida em que representam tipos cromáticos extremos e contrastantes, com expressão cartográfica mais extensiva do que os corpos pegmatíticos. Como linha de investigação inovadora, capaz de apoiar a prospecção de pegmatitos através de detecção remota, ainda se obtiveram medidas de reflectância de produtos litológicos pegmatíticos e seus encaixantes produtivos. O correspondente levantamento realizou-se com recurso a um espectroradiómetro tendo os espectros obtidos sido organizados numa base de dados específica. Estes podem ser correlacionados com determinadas oscilações espectrais nas imagens de satélite constituindo assim um acervo útil a utilizar no processamento de imagens, designadamente multi- e hiperespectrais. Da análise efectuada aos espectros, verificou-se que os respeitantes a massas de quartzo se revelaram mais distintos. Também foi possível separar do ponto de vista espectral encaixantes leucograníticos e testar a influência da cobertura dos substractos exumados por líquenes. Verificou- se que a partir de percentagens de recobrimento de 35%, o sinal espectral e efectivamente homogeneizado, impossibilitando a discriminação litológica. Considerando o crescente valor estratégico, económico e tecnológico atribuído aos recursos pegmatíticos e atendendo à inadequação de muitos outros métodos de prospecção, vislumbra-se aplicabilidade efectiva para as metodologias aqui exploradas.Within the framework of the R & D activities of the company Sinergeo Ltd., the project PROSPEG (no 11480), dedicated to the investigation through prospecting and research of granitic pegmatites, co-funded by “ON.2 – O Novo Norte” and QREN, through the European Regional Development Fund (ERDF), resulted from a co-promotion with the University of Minho. The overall objective of this project is the development of pegmatites prospecting programs in the Portuguese territory, using as main via for the primary approach to research areas, remote mapping analysis and remote sensing methodologies. The investigation in this domain is justified by the difficult implementation of other geophysical and geochemical methods, given the lack of strong contrast between pegmatite and enclosing rocks. On the other hand, the remote mapping analysis and remote sensing inscription in strategic prospecting programs is also advantageous in cost/benefit terms and in terms of extension and density of coverage allowed. In a strategic phase the prospecting actions focused on areas, known as/or hypothetically fertile for pegmatites with economic interest. These areas are compartments of the Variscan Pegmatitic Province in North and Center Portugal. Here, pegmatites with high intrinsic, structural, morphological, mineralogical and economic diversity can be found, simultaneously representing different structural levels of emplacement and exhumation of individual pegmatitic sets and bodies. The supports chosen for remote mapping analysis were multispectral images from LANDSAT and SPOT sensors and images from Google Earth Pro. These were treated through digital processes like contrast broadening, RGB combination of spectral bands, principal components analysis and Maxver classification. The conjunction of these techniques turned more evident geometric, chromatic, textural and spectral patterns of the superficial expression of pegmatites and its prospecting indicators. By combining those processing procedures with indications of productive stripes and massifs, obtained from the analysis on the regional distribution of bodies in the considered areas, and using empiric geological-structural and morphological criteria, it was possible to select a set of more restricted areas on which was done geological investigation. In a first phase, the geological investigation comprised geological mapping at 1:5000 scale, as a way for identifying sectors with pegmatitic bodies in potentially economic situation to be investigated through drillings. From these surveys were also discriminated some structural and lithological guides conditioning the presence of pegmatites in an innergranite context. The late-Variscan direction N30E seems to strictly condition the emplacement of bodies with higher volumes in the North and Center of Portugal. On the other hand, it is also noticeable that the pegmatites distribution reveals a coincident character with sectors of higher lithological diversification and heterogeneity, with the following facies tending to pegmatites: fine grained leucogranites with biotite nodules, yellowed by supergene leaching influence; facies with leucocratic tendency with diffuse pegmatitic differentiations; microporphyroid facies with flow evidences; miarolitic facies punctuated by pegmatitic bubbles; leucogranites with cordierite and garnet; biotitites established on the contact surface between granitic facies, and porphyroid granites reddened by hydrothermal and supergene hematization. The drilling program was, in some cases, well succeeded, having been intersected a pegmatitic body in depth, with considerable dimension. In other cases it was possible to delimit the development of known bodies in depth, subjected to exploitation in the past, and increase the amount of potential reserves. In the cases where destructive drilling methods were used, it was adopted, in an innovative way, the filming of boreholes combined with mineralometric cutting analysis, as a way to obtain correspondent drilling columns. As a result of the drilling program is also referred the optimization of geometric and conceptual pegmatite models which can represent paradigmatic conjectures amenable to be extrapolated to the Portuguese fields and, in this way, support subsequent prospecting programs. Also from the logs, here perceived as granitic columns productive in pegmatites, it was possible to infer fractionation, segregation and flow tendencies, capable of fomenting the appearance of transitional leucogranitic and pegmatitic magmas that may then evolve in situ or be mobilized and released to structural corridors. The trends seem oscillatory in some cases, with well-defined rhythms in the domes organization. From the remote sensing viewpoint the resulting facies are perceptible as they represent extreme and contrasting chromatic types with more extensive cartographic expression than the pegmatitic bodies. As a line of innovative research, capable of supporting pegmatites prospection through remote sensing, were also obtained reflectance measures of lithologic pegmatitic products and their productive enclosings. The correspondent survey was done through the use of a spectroradiometer and the spectra obtained were organized in a specific database. These can be correlated with some spectral oscillations in the satellite images, and thus represent a useful collection, to multi- and hyperspectral images processing. From the spectra analysis it was found that quartz masses spectra are more distinct. It was also possible to separate from a spectral viewpoint leucogranitic enclosings and test the influence of lichens cover. It was found that with percentages of coating as of 35% the spectral signal is effectively homogenized, turning impossible the lithological discrimination. Considering the increasing strategic, economic and technological value attributed to pegmatitic resources and considering the inadequacy of many other prospecting methods, the methodologies here explored are effectively applicable."ON.2 – O Novo Norte" e QRE
