Technology Choice, Change of Trade Structure, and A Case of Hungarian Economy

In the IT industry, there has been a remarkable increase in the demand for system LSI. A system LSI must be tailor-designed for each electrical appliance, and then produced. It is said that in recent years, this production method has made the IC cycle ambiguous. It can be sought that the choice of whether the economy pursues a development path centering on technology which is tradable or technology which is embodied in labor, depends on the historical background. In this paper, the economic background is explained in order to analyze and capture movements in the IT industry and technology. Then, an econometric model for Hungary has been constructed to estimate the effect of technological progress on the economy.

Technology Choice in the IT Industry and Changes of the Trade Structure

In the IT industry, there has been a remarkable increase in the demand for system LSI. A system LSI must be produced, tailor-designed for each electrical appliance. It is said that this production method has made the IC cycle ambiguous in recent years. It can be sought that the choice of whether the economy pursues a development path centering on technology which is tradable or technology which is embodied in labor, depends on the historical background. The relationship between these two types of technologies is changing rapidly every one or two years. In this background, the analysis is focused on the new trend of technology. In the section 2, the newest trend of technology in the field of system LSI is explained. Then, which kind of technology will be developed and how it will have an affect in the near future, is considered.

Abstract: The aim of this Final Project of Career, Implementation of Virtual Engineering with Joomla!, is to create a web software application where a multidisciplinary engineering project bases on the networking, working groups and the flexible working can be implemented. The networking is the job through the Information Technology and Communication (ITC) where working groups compounded of multidisciplinary and multiracial professions, different religions and located in different time zones are created. The multicultural environment, collaboration, flexibility and to share resources are the order of the day on this kind of groups. The flexibility is the ability to adaptability of workers to the productivity demand, with the trust which is placed on them by supervisor people who wait to receive the work completed in a specific form and date. These workers do not need either constant supervision or a fixed site where to do the job. Everything the workers need is on the network, as the information as the tools, that is why they become teleworkers. These workers demand a high use of their knowledge, so it can not be allowed to become obsolete. This would be a great misfortune. That is why they need to continue learning and knowing the new technologies emerging with the aim of getting new revenues. Workers do an intensive use of the information technology and communication, characterized by continuous innovation and technological change. These workers need a broad social and professional network with great power. This network is important to keep updated with innovations taking place at the companies, to apply for a new job, a new technology course etc.. Thanks to Internet services a bigger number of contacts are provided compared to earlier times. The software application of this project is compounded with enough tools with the aim of the workers can carry out their activity and maintenance of the links on their professional nets.

Distributed System for Cognitive Stimulation Over Interactive TV.

Descripción y evaluación de sistema de estimulación cognitiva a través de la TDT orientada a personas con enfermedad de Parkinson, con supervisión por parte de sus terapeutas de forma remota. Abstract: This paper details the full design, implementation, and validation of an e-health service in order to improve the community health care services for patients with cognitive disorders. Specifically, the new service allows Parkinson’s disease patients benefit from the possibility of doing cognitive stimulation therapy (CST) at home by using a familiar device such as a TV set. Its use instead of a PC could be a major advantage for some patients whose lack of familiarity with the use of a PC means that they can do therapy only in the presence of a therapist. For these patients this solution could bring about a great improvement in their autonomy. At the same time, this service provides therapists with the ability to conduct follow-up of therapy sessions via the web,benefiting from greater and easier control of the therapy exercises performed by patients and allowing them to customize new exercises in accordance with the particular needs of each patient. As a result, this kind of CST is considered to be a complement of other therapies oriented to the Parkinson patients. Furthermore, with small changes, the system could be useful for patients with a different cognitive disease such as Alzheimer’s or mild cognitive impairment.

Data Processing Modeling in Decision Support Systems.

Due to the advancement of both, information technology in general, and databases in particular; data storage devices are becoming cheaper and data processing speed is increasing. As result of this, organizations tend to store large volumes of data holding great potential information. Decision Support Systems, DSS try to use the stored data to obtain valuable information for organizations. In this paper, we use both data models and use cases to represent the functionality of data processing in DSS following Software Engineering processes. We propose a methodology to develop DSS in the Analysis phase, respective of data processing modeling. We have used, as a starting point, a data model adapted to the semantics involved in multidimensional databases or data warehouses, DW. Also, we have taken an algorithm that provides us with all the possible ways to automatically cross check multidimensional model data. Using the aforementioned, we propose diagrams and descriptions of use cases, which can be considered as patterns representing the DSS functionality, in regard to DW data processing, DW on which DSS are based. We highlight the reusability and automation benefits that this can be achieved, and we think this study can serve as a guide in the development of DSS.

Procesos de dualización en la sociedad de la información: algunas polémicas públicas de índole tecnológica

La tecnología ha cambiado el mundo, pero las consecuencias de estos cambios en la sociedad no siempre se han pronosticado bien. Las Tecnologías de la Información transformaron el método de producción industrial. La nueva industria produce ideas y conceptos, no objetos. Este cambio ha dado como resultado una sociedad dualizada, ha desaparecido gran parte de la clase media y han aumentado las diferencias entre la clase alta y la baja. Las exigencias educativas de los nuevos puestos de trabajo innovadores son superiores a los de la industria tradicional, pero inferiores en los puestos de trabajo de producción. Además, el número de puestos de trabajo disponibles de este tipo es menor que en la industria tradicional, se necesita menos mano de obra, los procesos se pueden automatizar, las tareas mecánicas se aprenden en poco tiempo y son trabajos temporales, cuyo número dependerá de la demanda global. Para que el proceso de innovación funcione, las empresas se reúnen en las zonas financieras de grandes ciudades, como Nueva York o Londres, que fueron las primeras con acceso a las redes de telecomunicación. De esta manera se producen sinergias que contribuyen a mejorar el proceso innovador global. Estas ideas y conceptos que cambian el mundo necesitan de este entorno de producción, que no puede ser replicado, y son tan importantes que su acceso está restringido para la mayor parte del mundo por distintos mecanismos de control. El despliegue de las redes de telecomunicaciones inalámbricas ha sido enorme en los últimos años. El cliente busca llamar desde cualquier lugar y llevar un acceso a Internet en teléfono móvil. Para conseguirlo, las operadoras de telefonía móvil necesitan poner antenas de telefonía móvil en las ciudades, pero la instalación cerca de edificios no está siendo fácil. Pocos quieren tener una antena cerca por los problemas de salud de las personas que padecen los que ya viven o trabajan cerca de una. Los efectos del electromagnetismo en los seres humanos no están claros y provocan desconfianza hacia las antenas. La digitalización de los contenidos, que ha sido necesaria para transmitir contenido en Internet, permite que cualquier persona con un ordenador y una conexión a Internet pueda publicar un disco, una película o un libro. Pero esa persona también puede copiar los originales y enviarlos a cualquier lugar del mundo sin el permiso del autor. Con el fin de controlar la copia no autorizada, los derechos de autor se están usando para cambiar leyes e incluir sistemas de censura en Internet. Estos sistemas permiten a los autores eliminar el contenido ilegal, pero también pueden ser usados para censurar cualquier tipo de información. El control de la información es poder y usarlo de una manera o de otra afecta a todo el planeta. El problema no es la tecnología, que es solo una herramienta, es la forma que tienen los gobiernos y las grandes empresas de usarlo. Technology has changed the world, but the consequences of these changes in society have not always been well predicted. The Information Technology transformed the industrial production method. The new industry produces ideas and concepts, not objects. This change has resulted in a society dualized, most of the middle class has disappeared and the differences between high and low class have increased. The educational requirements of new innovative jobs are higher than the ones of the traditional industry, but lower in production jobs. Moreover, the number of available jobs of this type is lower than in the traditional industry, it takes less manpower, processes can be automated, mechanical tasks are learned in a short time and jobs are temporary, whose number depends on global demand. For the innovation process works, companies meet in the business districts of large cities, like New York or London, which were the first with access to telecommunications networks. This will produce synergies that improve the overall innovation process. These ideas and concepts that change the world need this production environment, which cannot be replicated, and are so important that their access is restricted to most of the world by different control mechanisms. The deploy of wireless telecommunications networks has been enormous in recent years. The client seeks to call from anywhere and to bring Internet access in his mobile phone. To achieve this, mobile operators need to put cell towers in cities, but the installation near buildings is not being easy. Just a few want to have an antenna closely because of the health problems suffered by people who already live or work near one. The effects of electromagnetism in humans are unclear and cause distrust of antennas. The digitization of content, which has been necessary to transmit Internet content, allows anyone with a computer and an Internet connection to be able to publish an album, a movie or a book. But that person can also copy the originals and send them anywhere in the world without the author's permission. In order to control the unauthorized copying, copyright is being used to change laws and include Internet censorship systems. These systems allow authors to eliminate illegal content, but may also be used to censor any information. The control of knowledge is power and using it in one way or another affects the whole planet. The problem is not technology, which is just a tool, but the way that governments and large corporations use it.

Ensayos de seguridad eléctrica orientados a la vigilancia del mercado

El presente estudio recopila los diferentes bancos de pruebas de EMC, Radio, SAR y seguridad eléctrica que se utiliza en la vigilancia del mercado. Describe las pruebas realizadas por el Estado español para llevar a cabo el seguimiento y control de los equipos vendidos. En primer lugar se presenta una descripción cualitativa de los ambientes clasificados por requisitos que explica en qué consisten las pruebas que se hacen, cómo se configura el entorno de medida y cuáles son los equipos que se deben utilizar. Está ilustrado con fotografías de los bastidores, antenas, amplificadores, generadores y otros equipos que la SETSI tiene en su laboratorio en El Casar (Guadalajara). La vigilancia de los equipos se realiza periódicamente en los estados miembros de la Unión Europea. Los funcionarios responsables también se reúnen periódicamente a nivel europeo para sacar conclusiones y hacer proyecciones futuras. El equipo adquirido en centros comerciales de venta al público, después de poco más de un mes, en el que se pasan las pruebas, vuelve a la cadena de comercialización, por lo que los dispositivos no se puedan dañar. Las pruebas realizadas en el laboratorio no pueden ser perjudiciales para los dispositivos por lo que es necesario tomar precauciones en la ejecución de las pruebas. El centro del PFC es el área de la Seguridad Eléctrica. El capítulo 4 es una reproducción de la Norma internacional IEC 60950-1:2007/A11 sobre seguridad en equipos de tecnología de la información adaptada a los requisitos de la vigilancia de mercado. Las autoridades competentes se basan en este estándar para evaluar y garantizar la seguridad del usuario en los equipos de consumo. Diseñados los procedimientos de ensayo y montado un banco de acuerdo a estos ensayos, se ha preparado un manual de operador, capítulo 5, en el que se recogen cada una de las pruebas y controles visuales que deben realizarse para probar que el equipo es conforme. Para finalizar, en el capítulo 6, se ejecutan ensayos de ejemplo sobre tres dispositivos de prueba y se elaboran las correspondientes hojas de ensayo. El propósito es proporcionar al operador un manual completo del banco de seguridad eléctrica, es por ello que en el manual de operador se han repetido muchos fragmentos de la norma para facilitar al operador el objetivo concreto de las pruebas y el acceso fácil a la información. This dissertation presents the different test benches of EMC, Radio, SAR and Electrical Safety that are used in market surveillance. Describes the tests performed by the Spanish State to carry out the monitoring and control of equipment sold. First a qualitative description of the environments classified by requisites that explains in that consist the tests that are make it, how it configures the measure environment and which are the equipment that it should use. It is illustrated with photographs of the racks, antennas, amplifiers, generators and other equipment that the S.E.T.S.I has in its laboratory on El Casar (Guadalajara). The surveillance of equipment is performed periodically in the member states of the European Union. Responsible officials also periodically meet at European level to draw conclusions and make future projections. The equipment purchased in malls public sale, after little more than a month, in which the tests are passed, returned to the trade chain, which is why the devices cannot be damaged. The tests done in the laboratory may not be harmful for devices are thus necessary to take precautions in the execution of the tests. The center of this dissertation is the area of Electrical Safety. Chapter 4 is a reproduction of the International Standard IEC 60950-1:2007/A11 safety in teams of information technology, adapted to the requirements of market surveillance. The competent authorities are based on this standard to assess and ensure the user's safety in the consumption equipment. Designed test procedures and mounted on a bench according to these tests, it has prepared a manual operator, in Chapter 5, with each of the tests and visual inspections in order to prove that the equipment complies. Finally, in Chapter 6, such tests run on three devices are developed test and test some leaves. The purpose of this book is to provide an operator manual of the bench of electrical safety, which is why the operator manual have been repeated fragments of the standard, in chapter 5, to facilitate the operator to test execution and access to information.

Repercusión y análisis de las nuevas tecnologías en el entorno educativo del siglo XXI

Desde que se implantó la Sociedad de la Información, educadores e investigadores de todo el mundo han discutido y reflexionado sobre temáticas acerca de cómo deben ser usadas las Tecnologías de la Información y la Comunicación (TIC) para apoyar los aprendizajes, y cómo estas herramientas pueden ser útiles para mejorar los resultados académicos. Vivimos en una sociedad dinámica, sujeta a continuos cambios que afectan a cada una de los sectores de nuestra vida. El auge de las TIC ha transformado nuestro modo de pensar, de relacionarnos e incluso la manera de enseñar y de aprender. De ahí que la incorporación de las TIC a la sociedad en general y, de forma específica, al mundo de la educación se perciba hoy, como una realidad cada vez más consolidada y también como una necesidad. Por eso, este trabajo tiene como objetivo fundamental la evaluación de la implantación y el desarrollo que la educación y las TIC han tenido desde comienzos del siglo XXI hasta nuestros días. Este trabajo se dividirá en dos partes diferenciadas y complementarias. En una primera sección se presenta el marco teórico de los pilares fundamentales que sustentan la interacción entre educación y nuevas tecnologías y lo que ello conlleva. Un segundo apartado presenta el diseño metodológico de la investigación y los resultados alcanzados al aplicar instrumentos de evaluación en un centro escolar y su posterior análisis e interpretación de los resultados en referencia al impacto de las nuevas tecnologías en las aulas. ABSTRACT Since Information Society was introduced, educators and researchers from around the world have discussed and have reflected on issues about how the Information Technology and Communication (ICT) must be used to support learning, and how these tools can be useful for improving academic outcomes. We live in a dynamic society that is subject to continuous changes affecting every sector of our life. The growth of ICT has transformed the way we think and interact and even the way of teaching and learning. Hence, the incorporation of ICT in society in general and, specifically, in the world of education today is perceived as an increasingly consolidated reality and also as a necessity. Therefore, this work has as main objective the evaluation of the implementation and the development that education and ICT have had since the beginning of the XXI century to today. This work is divided into two distinct and complementary parts. The first section presents the theoretical framework of the pillars that support the interaction between education and new technology and what it entails. The second section presents the methodology of the research and results achieved by applying assessment instruments in a school and its subsequent analysis and interpretation of the results concerning to the impact of new technologies in the classrooms.

It is a project type dialog box, created, compiled and released with the integrated development tool Microsoft Visual Studio 2010. The architecture is structured in three layers: the user interface, business layer and data access layer. It has been necessary to configure the project with the support CLR -Common Languages Runtime – in order to implement the reporting functionality. The software application is submitted with the project report and its annexes to the following documents: Functional Requirements Specifications - Detailed User Interface Specifications, Technical Design and User Guide.

Aplicación de nuevas tecnologías en los sistemas de alumbrado

A medida que transcurre el tiempo la sociedad evoluciona, las ciudades crecen, se modernizan, mejoran su infraestructura y se ofrecen más y mejores servicios a sus ciudadanos. Esto ha hecho que durante muchos años las ciudades se hayan desarrollado sin pensar en lo que vendrá más adelante, contaminando el medio ambiente y consumiendo mucha energía y de forma ineficiente. Ante esta situación, y gracias a las innovaciones tecnológicas en materia de comunicaciones, se están adoptando medidas para dirigir la evolución de las ciudades hacia un modelo de ciudad inteligente y sostenible. Las redes de comunicaciones constituyen uno de los pilares sobre los que se asienta la sociedad, que se encuentra siempre en contacto con su entorno. Cada vez más, se tiene una mayor necesidad de conocer lo que ocurre en el entorno en tiempo real solicitando información climatológica en una determinada ubicación, permitiendo conocer el estado del tráfico para elegir la ruta hacia el trabajo, saber el tiempo que tardará el autobús en llegar a la parada, etc. Como éstos, se podrían citar muchos más ejemplos de necesidades y servicios que demandan hoy día la sociedad y que, seguramente, nadie pensaba que las iba a necesitar hace unos años. Muchos de estos servicios en tiempo real se consiguen gracias a las redes de sensores inalámbricas. Consiste en desplegar una serie de diminutos sensores en una zona determinada con el objetivo de recoger la información del medio, procesarla y modelarla para que esté disponible para los usuarios. Observando la tendencia seguida por las Tecnologías de la Información y de las Comunicaciones (TIC) se puede constatar una continua evolución hacia los dispositivos embedidos, de cada vez más pequeño tamaño y menor consumo y, al mismo tiempo, con mayor capacidad de proceso y memoria y facilidad para las comunicaciones. Siguiendo esta línea, se está construyendo la ciudad inteligente con capacidad para pensar y tomar decisiones, pero hay que dotarla de cierto grado de eficiencia. Se trata de aprovechar los recursos de la naturaleza para crear fuentes de energías limpias e ilimitadas. Empleando las tecnologías oportunas para transformar, por ejemplo, la energía del Sol o la energía del viento en electricidad, se puede alcanzar el modelo de ciudad que se pretende. ABSTRACT. As time passes society evolves, cities grow, modernize, improve their infrastructure and offer more and better services to their citizens. This has made for many years cities have developed without thinking about what will come later , polluting the environment and high energy consuming and inefficient . Given this situation, and thanks to the Technological innovations in communications, is being taken to direct the evolution of cities towards a smart city model sustainable. Communication networks are one of the pillars on which society rests, which is always in contact with their environment. Increasingly, there is a greater need to know what happens in the real-time environment requesting weather information in a certain location , allowing know the traffic to choose the route to work , namely the time take the bus to get to the bus stop, etc. . As these, you could cite many more Examples of needs and services that society demands today and, surely, no one thought that was going to need a few years ago. Many of these real-time services are achieved through networks wireless sensors. Is to deploy a series of sensors in a tiny given area in order to collect information from the environment, process and shape it to make it available to users. Observing the trend followed by the Information Technology and Communications (ICT ) can finding an evolving toward embeded devices of increasingly small size and lower power consumption and at the same time, higher capacity process and memory ease communications. Following this line, is under construction with capacity smart city to think and make decisions, but you have to give it some degree of efficiency. It seeks to harness the resources of nature to create clean energy sources and unlimited. Using appropriate technologies to transform, for example, energy from the sun or wind energy into electricity, it can achieve the model city intended.

Autonomous classification models in ubiquitous environments

Stream-mining approach is defined as a set of cutting-edge techniques designed to process streams of data in real time, in order to extract knowledge. In the particular case of classification, stream-mining has to adapt its behaviour to the volatile underlying data distributions, what has been called concept drift. Moreover, it is important to note that concept drift may lead to situations where predictive models become invalid and have therefore to be updated to represent the actual concepts that data poses. In this context, there is a specific type of concept drift, known as recurrent concept drift, where the concepts represented by data have already appeared in the past. In those cases the learning process could be saved or at least minimized by applying a previously trained model. This could be extremely useful in ubiquitous environments that are characterized by the existence of resource constrained devices. To deal with the aforementioned scenario, meta-models can be used in the process of enhancing the drift detection mechanisms used by data stream algorithms, by representing and predicting when the change will occur. There are some real-world situations where a concept reappears, as in the case of intrusion detection systems (IDS), where the same incidents or an adaptation of them usually reappear over time. In these environments the early prediction of drift by means of a better knowledge of past models can help to anticipate to the change, thus improving efficiency of the model regarding the training instances needed. By means of using meta-models as a recurrent drift detection mechanism, the ability to share concepts representations among different data mining processes is open. That kind of exchanges could improve the accuracy of the resultant local model as such model may benefit from patterns similar to the local concept that were observed in other scenarios, but not yet locally. This would also improve the efficiency of training instances used during the classification process, as long as the exchange of models would aid in the application of already trained recurrent models, that have been previously seen by any of the collaborative devices. Which it is to say that the scope of recurrence detection and representation is broaden. In fact the detection, representation and exchange of concept drift patterns would be extremely useful for the law enforcement activities fighting against cyber crime. Being the information exchange one of the main pillars of cooperation, national units would benefit from the experience and knowledge gained by third parties. Moreover, in the specific scope of critical infrastructures protection it is crucial to count with information exchange mechanisms, both from a strategical and technical scope. The exchange of concept drift detection schemes in cyber security environments would aid in the process of preventing, detecting and effectively responding to threads in cyber space. Furthermore, as a complement of meta-models, a mechanism to assess the similarity between classification models is also needed when dealing with recurrent concepts. In this context, when reusing a previously trained model a rough comparison between concepts is usually made, applying boolean logic. The introduction of fuzzy logic comparisons between models could lead to a better efficient reuse of previously seen concepts, by applying not just equal models, but also similar ones. This work faces the aforementioned open issues by means of: the MMPRec system, that integrates a meta-model mechanism and a fuzzy similarity function; a collaborative environment to share meta-models between different devices; a recurrent drift generator that allows to test the usefulness of recurrent drift systems, as it is the case of MMPRec. Moreover, this thesis presents an experimental validation of the proposed contributions using synthetic and real datasets.

O USO DAS TECNOLOGIAS DA INFORMAÇÃO E COMUNICAÇÃO NO CAMPO OPERACIONAL DA GUARDA CIVIL METROPOLITANA DE SÃO PAULO DESAFIOS À GESTÃO DE PESSOAS

Esta dissertação apresenta um estudo exploratório sobre a experiência de implantação de um sistema digital de segurança. O estudo teve como locus a Guarda Civil Metropolitana de São Paulo e o objetivo geral da pesquisa é analisar o uso das tecnologias da informação e comunicação no campo operacional da organização. Primeiramente foi realizada a pesquisa bibliográfica para rastreamento de temas análogos. Foi possível verificar a escassez de estudos sobre as tecnologias da informação e comunicação na Segurança Pública no Brasil. Dos raros trabalhos encontrados o que deu inspiração para essa pesquisa foi o experimento realizado em Brasília, na área de Gestão do Conhecimento e da Tecnologia da Informação, que investigou a integração de sistemas de info rmações na Segurança Pública do Distrito Federal. Para a realização deste estudo de caso adotou-se a metodologia qualitativa com pesquisas bibliográfica, documental e de campo (entrevistas e observações diretas). Os resultados obtidos demonstram a necessidade de investimentos em tecnologias da informação e comunicação, objetivando a integração e a interoperabilidade das organizações de Segurança Pública. Os resultados também confirmaram os achados em pesquisas e estudos sobre a violência urbana que apontam que só os investimentos na estrutura técnica, em pessoal, em gestão de segurança, chamada política de combate à violência e à criminalidade, não resolve. É preciso urgência na gestão de políticas públicas integradas para combater as causas provocativas da violência e da criminalidade que são a miséria crescente, o desemprego, a falta de serviços públicos eficientes, em especial no setor da saúde e da educação e a ausência de políticas sociais, todos entendidos como violência.(AU)

U.S.-Taiwan Relations: A Study on the Taiwan Relations Act

The relationship between the United States and Taiwan is of great importance to both parties. Taiwan offers certain strategic opportunities for the promotion of American national security interests, and the U.S. accordingly provides Taiwan with support of both a defensive and diplomatic nature. The official U.S. policies regarding relations with Taiwan are enumerated in the Taiwan Relations Act (United States Code Title 22 Chapter 48 Sections 3301 - 3316). The act, approved by the U.S. Congress in 1967, stipulates the terms of the bilateral relationship with regard to national defense and diplomatic relations among other factors. This paper seeks to obtain a more developed picture of sentiments on both sides of this relationship in order to understand better the U.S.'s influence and power in Taiwan and in the region.
