    Challenges and complexities in application of LCA approaches in the case of ICT for a sustainable future

    In this work, three of many ICT-specific challenges of LCA are discussed. First, the inconsistency versus uncertainty is reviewed with regard to the meta-technological nature of ICT. As an example, the semiconductor technologies are used to highlight the complexities especially with respect to energy and water consumption. The need for specific representations and metric to separately assess products and technologies is discussed. It is highlighted that applying product-oriented approaches would result in abandoning or disfavoring of new technologies that could otherwise help toward a better world. Second, several believed-untouchable hot spots are highlighted to emphasize on their importance and footprint. The list includes, but not limited to, i) User Computer-Interfaces (UCIs), especially screens and displays, ii) Network-Computer Interlaces (NCIs), such as electronic and optical ports, and iii) electricity power interfaces. In addition, considering cross-regional social and economic impacts, and also taking into account the marketing nature of the need for many ICT's product and services in both forms of hardware and software, the complexity of End of Life (EoL) stage of ICT products, technologies, and services is explored. Finally, the impact of smart management and intelligence, and in general software, in ICT solutions and products is highlighted. In particular, it is observed that, even using the same technology, the significance of software could be highly variable depending on the level of intelligence and awareness deployed. With examples from an interconnected network of data centers managed using Dynamic Voltage and Frequency Scaling (DVFS) technology and smart cooling systems, it is shown that the unadjusted assessments could be highly uncertain, and even inconsistent, in calculating the management component's significance on the ICT impacts.Comment: 10 pages.

    El informe anual Horizon investiga, identifica y clasifica las tecnologías emergentes que los expertos que lo elaboran prevén tendrán un impacto en la enseñanza aprendizaje, la investigación y la producción creativa en el contexto educativo de la enseñanza superior. También estudia las tendencias clave que permiten prever el uso que se hará de las mismas y los retos que ellos suponen para las aulas. Cada edición identifica seis tecnologías o prácticas. Dos cuyo uso se prevé emergerá en un futuro inmediato (un año o menos) dos que emergerán a medio plazo (en dos o tres años) y dos previstas a más largo plazo (5 años)

    The era of industrial revolution 4.0 or the term Indonesian roadmap making 4.0. will change the structure of human life both ways of life, how to interact and communicate and how to receive information for each person with the emergence of supercomputers (smart phones), internet of things, human-machine interfaces, artificial intelligence or artificial intelligence, autonomous vehicles, 3D printing or digitalization, optimizing the human brain with genetic editing and the development of neurotechnology that combines automation with cyber technology, this needs to be balanced with increasing human resources from the pattern in educating students with learning methods taught in basic education to tertiary education, this will bring changes to design, strategy , methods, approaches and models for delivering material or content in our existing education curriculum. This change brings a shift in the substance of the learning method that has an impact on the change significantly in the learning process which now uses information technology such as the use of laptops, andoid-based smartphones, IOS, internet, and new methods for educators to transform learning more effectively and efficiently, with the methods and strategies used to be able to change the learning outcome resulting from our education, which is expected to face the era of the industrial revolution
