This study aims to describe the overall aspects of future technologies in Korea based on the new taxonomy of technology foresight ; Theme, Area and Paradigm. This taxonomy is designed to overcome and supplement several studies on technology foresights which are judged not to capture the whole aspects of future technologies. Future technologies in Korea will be influenced by the Information and Communication Technology Paradigm over 20-30 years, and by the Biotechnology Paradigm after that period. Expansion of researches in electronics, information and communication is noticeable features in engineering. The application of biotechnology technique and health/environment technologies are emerging in bioscience area. Also there appear new areas related to the trends of engineering and bioscience in natural science. Current research patterns focusing physics, chemistry and engineering in Korea should be changed to those of the advanced countries which emphasize bioscience. Time lag to the world frontier is over 5-6 years, but the lag is expected to be reduced. The shortage of manpower and research funds are pointed as the biggest barrier for the realization of future technologies.

Entering into the 21st century, digital culture and the innovation of media technology have drastically changed our understanding of the concept of space. Increased availability of information made possible by technological advancement has, directly or indirectly, contributed to the development of space design, which, in turn, offers a possibility for a new paradigm in space design. Given these fundamental changes, this study seeks to explore how to understand the expansion of the concept of space. In order to answer this question, this study investigates de-materialization tendency in modern architectural design such as transparency, anti-gravity, complexity and simultaneity of space. It examines the interaction-oriented nature of space among human, information and time. Finally, based on concepts such as new hyper-surface, which transcend the limitations of space and time, it explores new emerging trends in space design.

The aim of this study is to map the intellectual structure of the field of Organic Light Emitting Diode(OLED). Co-word analysis was employed to reveal patterns and trends in the OLED field by measuring the association strengths of terms representative of relevant publications or other texts produced in OLED field. Data were collected from INSPEC. Important keywords were extracted from author keywords. These author keywords were further standardized. In order to trace the dynamic changes of the OLED field, present the technology mapping. The results show that the OLED field has some established research theme and it also changes rapidly to embrace new themes.

The importance of floating photovoltaic systems has recently been emerging to address some issues arising from the installation of conventional ground-mounted photovoltaics. Floating photovoltaics have a few advantages such as cutting down land usage, reducing water evaporation or creating algae. Though there is still necessity to supplement with technical issues: mechanical stability, reliability and long-term durability of floaters and modules. In this paper, we focus the current level of packaging development and introduce research trends that could be applied to next-generation floating photovoltaics.

과거에는 주로 기술적 발전에 의해 기술이 개발되면서 기술 개발의 상업성과 경제성에 많은 의문이 제기되고 있다. 따라서 최근에는 시장과 수요를 강조하여야 한다는 요구가 각 분야에서 도출되고 있다. 즉 기술 자체의 발전에 의해서 기술이 개발되어온 측면이 많아 기술 개발의 결과가 연구실에서 사장되거나 고객에게 다가가지 못하고 개발을 위한 개발에 그치는 경우가 빈번해지면서 기술이나 이를 활용한 아이템 개발시 고객의 소리를 청취하고 이를 적극 반영하여야 한다는 것이 일반화되고 있다. 이에 본 고에서는 시장 고객 중심으로의 접근 체계 및 프로세스, 방법을 마련하고 이를 통해 시도된 미래 유망 IT 융합기술 발굴 시뮬레이션 결과를 중심으로 서술코자 한다.

Recent years have shown a great interest of public in buying and selling of crypto/digital currency. With hundreds of digital currencies in financial market, bitcoin remains the most widely used, adapted, and accepted currency around the world. However, the critics of bitcoin still consider it a threat to modern day power usage. This paper discusses the important pitfalls, pros, and cons related to bitcoin's energy consumption. The paper begins by highlighting the flexibilities cryptocurrency can bring to online money transfers compared to traditional 'fiat' architecture. Then, the focus of the paper entirely remains on listing various facts related to bitcoin's energy utilization including a brief description of several emerging approaches for energy optimization. This paper is concluded by revealing key current challenges associated to bitcoin's energy usage.

This study has identified human performance research issues associated with the implementation of new technology in nuclear power plants (NPPs). To identify the research issues, current industry developments and trends were evaluated in the areas of reactor technology, instrumentation and control technology, human-system integration technology, and human factors engineering (HFE) methods and tools. The issues were prioritized into four categories based on evaluations provided by 14 independent subject matter experts representing vendors, utilities, research organizations and regulators. Twenty issues were categorized into the top priority category. The study also identifies the priority of each issue and the rationale for those in the top priority category. The top priority issues were then organized into research program areas of: New Concepts of Operation using Multi-agent Teams, Human-system Interface Design, Complexity Issues in Advanced Systems, Operating Experience of New and Modernized Plants, and HFE Methods and Tools. The results can serve as input to the development of a long-term strategy and plan for addressing human performance in these areas to support the safe operation of new NPPs.

Hydrogen is emerging as clean fuel and important industrial raw materials. The hydrogen gas is not sensed by the human olfactory system, But the combustion characteristics of hydrogen is that the ignition is very easy, the propagation speed of the flame is very fast and explosion limits is a wide range of 4 %~75 %. Therefore it is extremely in danger, and the need for its leakage detection technologies is especially important in places such as a production, transportation, storage and usage. The hydrogen sensors are classified with ceramic type, semiconductor type, optical type, electrochemical type and so on. Hydrogen sensors and their technologies are reviewed in detail for materials, fabrication process, sensing characteristics, good point and faults, and production and utilization of sensors be discussed.

The amount of electrical energy has been increased with the rapid development of the industrial society. Accordingly, operating voltage of the power equipment and facility capacity are continuously increasing. Development trends of recent high-voltage electrical equipment are ultra high-voltage, large-capacity and compact. Early diagnosis of a failure of the power plant has been emerging as an important task as to supply high quality power to users. In this study, we have tried to develope an algorithm for distinguishing an arc fault signal generated in the power plant by using UV sensor.
