The blockchain is still new and unfamiliar. But blockchain appears to shake an entire technology innovation system. Blockchain is rapidly drawing attention in that it will be able to fundamentally revolutionize industry ecosystem. While cryptocurrency transactions and market capitalization have been popular in mass media, several platform operators in non-cryptocurrency areas such as jewelry, social networks, and entertainment, are also moving to introduce blockchain technology in full swing. In this brief note, we intend to present integrated theoretical strands to summarize various prospects for blockchain technology. Further, we want to provide a reflection as to whether this new technology gives opportunities, challenges, or risks to future society. Particularly, we point out one of its alternative and promising adoption that gives way to new forms of decentralized and autonomous organizations (DAOs).

Water pollution problems of urban rivers due to the urbanization and industrialization have been the subject of public attention. In particular, considering the fact that the characteristics of water cycle of each basin change dramatically through the development of new towns, a large number of concerns about future water quality have been raised. However, reasonable measures to predict future water quality quantitatively have not been presented by this moment. In this study, by the linkage of annual unit load generation based on long-term monitoring results of the ministry of environment (MOE) to a semi-distributed rainfall runoff model, SWMM (Storm Water Management Model), we proposed a new methodology to estimate future water quality macroscopically and testified it to verify its applicability for the estimation of future water quality of a small watershed at G new town. As a result of the estimation using Y-EMC (Yearly based Event Mean Concentration), future water quality were simulated as BOD 18.7, T-N 16.1 and T-P 0.85 mg/L respectively which could not achieve the grade III of domestic river life guidance and these criteria could be satisfied by the reduction of domestic wastewater discharge load by over 80%. The results of this study are shown to be utilized for one of basic tools to estimate and manage water quality of urban rivers in the course of new town developments.

The systematic study of the future began with curiosity and imagination about the future; a unique trait of human mental effort-and this seems to be based on the idea that the future can be different depending on current choices or effort. In this sense, it would be seemly to encourage more interest and academic study on the progress of future fashion. In this study, we examine recent changes of fashion material; e.g. that which science and technology have more impact and importance in futuristic fashion since the 1990�s. The period analysed is from the1990's to the present and related data from recent fashion collections and fashion books has also been included The current prediction of the future is largely based on what was formed between the 19th Century and the 20th Century which has persisted until now and has been influenced by the view that science will play a bigger role in the future. This is especially reflected in fashion which chiefly represents material culture. New materials used for fashion are strong and permanently durable, in addition to being very light, thin, flexible, hygienic, ecological and comfortable to wear-almost like a second skin. These fashionable new materials roughly function in two different ways according to external and internal characteristics. First, they cause external change. Second, they exemplify or allow new functions. Examples of external change are the use of silver color, achromatic color, metallic material, smooth-to-the-touch shiny material and the use of luminous material. Examples of the extended function of clothing through the use of new materials are the use of conducting thread, the use of special material for blocking & opening and the use of material which changes colors as the surroundings change. These days, the use of new material which changes its appearance is a novelty unique to the fashion world but we also expect to witness the debut of diverse new materials with extended inner functions.

In general, reliability of AHP depends on pairwise comparison of evaluators. In addition, human judgment on the importance of alternatives or criteria is always imprecise and vague. The Fuzzy AHP technique is suggested and used widely recently. In this paper, we prioritize future energy technology development for well focused R&D. We selected 3 criteria and 10 sub-criteria. According to the result in this study, the most important sub-criterion is the precedence over other competitive technology, the second is the possibility for fundamental technology acquisition, and the third is the improvement energy efficiency. The other side, the lowest important sub-criterion is the technology level compared with advanced countries.

The Korea Electric Power Corporation (KEPCO) recorded 2.9 trillion won deficit in the aftermath of the world financial crisis. KEPCO is trying to escape from the business crisis in every way; however, it is impossible to make huge profit by selling electricity alone. Overseas electrical utilities make profits by selling gas and heat along with electricity. However, it is difficult for KEPCO to enter the gas and the heat selling market because other public companies are already dealing with them. In this situation, improving the business is possible when KEPCO develops a new business model and creates added value using Korean advanced Power IT combined with electricity. This study shows a new business model using Power IT, based on a survey targeting managers in KEPCO branch office and electrical engineers in the field. We hope the new business model suggested in this study is adapted to the real field to create high value in the future.

Foresight, a major methodological tool in the STI policy toolbox, has recently featured new directions in methodological development, becoming influenced by progress in information and communication technologies and online tools. However, no overview of these directions has been available so far. Based on a literature review, an interactive workshop, and an international expert survey as well as expert interviews, the research presented here attempts to shed light onto some of the relevant issues by providing a structured overview of recent changes in order to further the debate on the future directions of methodological development in foresight. The paper outlines four clusters of emerging approaches in foresight:Integrated qualitative and quantitative approaches, IT-based and automated foresight, experiential foresight including new forms of communication and interaction such as visualization and gaming, and open and crowd-sourced approaches. The benefits and challenges of the approaches known so far are categorized and summarized, and areas of potential use for each of the clusters in STI contexts are identified.
