  • Porous materials play a vital role in science and technology. The ability to control their pore structures at the atomic, molecular, and nanometer scales enable interactions with atoms, ions and molecules to occur throughout the bulk of the material, for practical applications. Three-dimensional (3D) porous carbon-based materials (e.g., graphene aerogels/hydrogels, sponges and foams) made of graphene or graphene oxide-based networks have attracted considerable attention because they offer low density, high porosity, large surface area, excellent electrical conductivity and stable mechanical properties. Water pollution and associated environmental issues have become a hot topic in recent years. Rapid industrialization has led to a massive increase in the amount of wastewater that industries discharge into the environment. Water pollution is caused by oil spills, heavy metals, dyes, and organic compounds released by industry, as well as via unpredictable accidents. In addition, water pollution is also caused by radionuclides released by nuclear disasters or leakage. This review presents an overview of the state-of-the-art synthesis methodologies of 3D porous graphene materials and highlights their synthesis for environmental applications. The various synthetic methods used to prepare these 3D materials are discussed, particularly template-free self-assembly methods, and template-directed methods. Some key results are summarized, where 3D graphene materials have been used for the adsorption of dyes, heavy metals, and radioactive materials from polluted environments.

  • Purpose - The purpose of this study is to shed light on the healthcare management systems in correlation with the advancing technological world, as well as the many diversified systems in different Asian countries. Research design, data, and methodology - This is a comprehensive study on the past researches that have been conducted on the field of healthcare management in different Asian countries. The different types of healthcare coverages were examined by country. Additionally, incorporating the healthcare system with technology is also investigated in this research. Results - The results have shown that there is a rapid incorporation of the technology in today's society with the healthcare systems. This has promising effects for the future, and for the different healthcare systems that exist within other Asian countries around the world. Conclusion - Quality healthcare for people are still elusive, and the healthcare management should improve on ways to better take care of their patients for the near future. By shedding light on the healthcare systems of Asian countries, an idea of the similarities and differences each hold can be assessed and utilized for future goals. By incorporating technology into healthcare systems, this will help in improving the overall care and quality-of-life that patients receive for the future.

  • The Cyber-Physical System (CPS) is a term describing a broad range of complex, multi-disciplinary, physically-aware next generation engineered system that integrates embedded computing technologies (cyber part) into the physical world. In order to define and understand CPS more precisely, this article presents a detailed survey of the related work, discussing the origin of CPS, the relations to other research fields, prevalent concepts, and practical applications. Further, this article enumerates an extensive set of technical challenges and uses specific applications to elaborate and provide insight into each specific concept. CPS is a very broad research area and therefore has diverse applications spanning different scales. Additionally, the next generation technologies are expected to play an important role on CPS research. All of CPS applications need to be designed considering the cutting-edge technologies, necessary system-level requirements, and overall impact on the real world.

  • This paper provides a basis for investigating 'The Origin of Artificial Species,' as a robot can be considered as an artificial creature. To design an artificial creature, its general internal architecture is presented and its artificial chromosomes are proposed as its essential components. Rity as an artificial creature is developed in a virtual world of PC to test the world's first robotic 'chromosomes,' which are a set of computerized DNA (Deoxyribonucleic acid) codes for creating robots (artificial creatures) that can have their own personality, and can ultimately reproduce their kind, or even evolve as a distinct species. The effectiveness of the artificial chromosomes is demonstrated by implanting the genetic code into two Ritys living in a virtual world, in order to define their personality.

  • Universities are considered important actors and drivers of socio-economic development in the regional innovation eco-system. This article investigates the role Kenyan universities and research institutes play in the development of regional innovation eco-system in the context of triple and Quadruple helices. A model involving Government, Industry, Universities and Society (Public) linkages in the regional innovation eco-system and with Information and Communication Technology as an enabler is used as a framework for analysing the nature of linkages in Kenya. The article uses literature review and case study methods to examine how universities and research institutes can spur the development of the innovation eco-systems. The research question is: what is the role of Kenyan universities and research institutes in spurring innovation ecosystems? Six cases of Kenyan universities and research institutes are considered in the light of Government Policy on Science, Technology and Innovation (STI) which is underpinned in Kenyan constitution 2010. The study contributes to the understanding of how deep collaboration among universities, government, research institutes, Science Cities, local, regional, national and international players spurs the creation of world-class innovation ecosystems which can contribute to regional development in developing countries like Kenya.

  • Human history show the whole society changed rapidly and found that the momentum and foundation of such change is " the advanced technology ",which is, the advanced knowledge. The world is newly established based upon openess, spaclalization and globalization, and the each nation and company should have to adopt all the existing frames to follow the new world reality. Today is the changing period from industrial society to information society, and information technology plays a great role. As the information society moves ahead, world economy and social infrastructure will be based upon network society and various information systems will make an integrated information system. This paper presents that to establish interior design related information in the age of information with radical change of previous way of thinking, cooperative information exchange system. Also substantial and effective communication systems should be made and continuing cooperation system of interior design information area should be formulated.d be formulated.
