Terrorist groups are currently using information and communication technologies (ICTs) to orchestrate their conventional attacks. More recently, terrorists have been developing a new form of capability within the cyber-arena to coordinate cyber-based attacks. This chapter identifies that cyber-terrorism capabilities are an integral, imperative, yet under-researched component in establishing, and enhancing cyber-terrorism risk assessment models for SCADA systems. This chapter examines a cyber-terrorism SCADA risk framework that has been adopted and validated by SCADA industry practitioners. The chapter proposes a high level managerial framework, which is designed to measure and protect SCADA systems from the threat of cyber-terrorism within Australia. The findings and results of an industry focus group are presented in support of the developed framework for SCADA industry acceptance.

This paper presents a distributed multi-agent scheme to detect and identify cyber threats on the protection systems of power grids. The integration of information and communication technologies (ICTs) into existing power grids builds critical cyberphysical energy systems CPESs) in which digital relays are networked cyber-physical components subject to various cyber threats. Cyber attacks on protection systems may mimic real faults, cause component failure, and disable the communication links. Agents utilize both cyber and physical properties to reinforce the detection technique and further distinguish cyber attacks from physical faults. This paper also introduces the problem of secure communicationprotocols and highlights the comparative studies for enhancing thesecurity of the protection systems. The proposed scheme is validatedusing a benchmark power system under various fault and cyber attack scenarios.

Hoy en día, en el mundo se están presentando grandes avances tecnológicos, lo que ha producido cambios en las vidas de las personas, las organizaciones, gobiernos, los Estados y en general en la vida en la tierra. Gracias a estos avances tecnológicos se han creado las TICS o Tecnologías de la Información y Comunicaciones, las cuales han permitido la simplificación de diferentes procesos, han cambiado la forma de interactuar de las personas y la manera de operar de las empresas. En países desarrollados las TICS han venido funcionando desde hace unas décadas pero en los países de Latinoamérica en especial Colombia, un país en vía de desarrollo con un potencial de crecimiento y tendencia al desarrollo, empezaron a hacer uso de estas tecnologías a principio del siglo XXI, trayendo grandes avances y beneficios a los colombianos. Actualmente Colombia es un país en el cual se desarrollan diferentes tipos de tecnologías como aplicaciones móviles, soluciones informáticas, herramientas online, videojuegos, entre otras, lo que ha permitido consolidar al país como un destino atractivo de inversión y proveedor de TICS a nivel mundial.

Durante os últimos 1O anos, em particular, tem-se assistido à descoberta e desenvolvimento de materiais com propriedades únicas e potencialmente úteis em vários domínios da Ciência e Tecnologia. Quer seja na área das Ciências Biomédicas e do Ambiente, na área das Novas Tecnologias de Informação e Comunicação ou nas Novas Tecnologias relacionadas com sistemas de Conversão e Armazenamento de Energia Eléctrica, encontram-se inúmeros exemplos de Novos Materiais com propriedades muito interessantes, e cujas aplicações inovadoras podem revolucionar o nosso Mundo. O presente trabalho é uma proposta de contextualização e experimentação do tema "Materiais Electrocrómicos e Mecaelectroquímicos" no Programa de Química de 12° Ano, nomeadamente na terceira Unidade - Plásticos, Vidros e Novos Materiais. Neste, é apresentada uma sub-unidade que possa integrar a unidade referida. Faz-se especial referência às aplicações dos polímeros condutores, que pela sua inovação e actualidade tomam a leccionação do tema mais apelativa, interessante e facilitadora de uma literacia científica. São apresentadas experiências laboratoriais demonstrativas e elucidativas do tema em questão. Como forma de apoiar a leccionação do referido tema, é apresentada a proposta de uma animação gráfica animada em Power Point. ABSTRACT: During the past 1O years, in particular, it has witnessed to the discovery and development of materials with unique properties and potentially useful in various fields of Science and Technology. There are numerous examples of new materials in different areas, such as Biomedical, Energy and Environmental Sciences and New information and Communication Technologies, with very interesting properties, and whose innovative applications can have an outstanding impact in our world. This dissertation is a proposal of contextualization and experimentation of theme "Electrochromic Materials and Electrochemical Artificial Muscles" in the Program of Chemistry, in 12th year, particularly in the third unit - Plastics, Glass and New Materials. lt will present a sub-unit that can integrate the unit above. The definitions and some applications of the Electrochromic Materials and Electrochemical Artificial Muscles are showed. Demonstrative and illustrative laboratory experiments of the theme are proposed. ln order to support the teaching of that subject, it is presented an animated graphical presentation in Power Point.

The intention of the article is to announce the needs of a curriculum Identified in the NicaraguanThis article analyses the potential of information and communication technologies from a rural social context approach. The author approaches the advantages of the social incorporation of this resource, its menaces and risks as well as the aspects that have to be valued when an impact on social development is expected. This perspective allows tackling the relation between ICTs and social concerns such as social inequality, gender equity, and community participation, among others. The article ends up presenting a reflection about some challenges in this matter.

Division de Educología (School of Education for Secondary Level) of Universidad Nacional in Costa Rica, (UNA) has been aware of the necessary planning and thought of a future that demands a continuous reflection between what is possible and what is desirable. In this sense, the formation of future educators of the country in different specialties, should promote not only the use of the technology, but also the development of critical and objective thinking that will embrace its advantages and its limitations in the noble exercise of what is teaching and learning. Under the light of these precepts, in the year 2007, the educational research activity emerged by the name of Didactic Resources for Learning with a bimodal focus. The present article exposes the main ideas that have been matured after an experience of more than two years with this course, and it is also searching for recapturing a responsible way of planning, implementing and managing the policies of ICTs (Information and Communication Technologies) for the bimodal learning in the context of the Division de Educología (School of Education for Secondary Level) of UNA.
