  • In Dongeuibogam "東醫寶鑑", Qian Yi(錢乙)'s had been reorganized in more elaborated ways, comprising Ju dan Gae(朱丹溪)'s 'Yang is always sufficient and Yin is always deficient theory(陽有餘陰不足論) and Li Dong Yuan(李東垣)'s 'Theory of the Spleen and Stomach(脾胃論)'. In organizing the contents, 5 Organs(五臟) were mostly concerned especially 'the Heart, the Fire (心火) and the Kidney, the Water(腎水)' as the axis and 'the Spleen and Stomach(脾胃)' as the center of 5 Organs. Based on this concept, the patterns of disharmonies were categorized and the table of content was organized. In this book, 'Deficiency-Excess and Nourishing-Draining(虛實補瀉)'is the basic treatment rule and the concept of 'Yin and Yang(陰陽)' and 'Exterior and Interior(表裏)' is considered to help tell the prognosis. This book has importance of systemizing Qian Yi(錢乙)'s , which was previously mentioned in Hyangyakjipseongbang("鄕藥集成方"),Euibangyoochui("醫方類聚"), Euirimchyalyo("醫林撮要"), by comprising the theories of Jin Yuan Si Da J ia -the four great masters of the Jin Yuan Dynasties(金元四大家).

  • There are unplugged computer science activities for elementary school students to learn the concept of the Internet. However, these activities are not enough to teach the concept of the Web because they focus on teaching how the Internet works. Since the Web is the core technology of the Third Industrial Revolution, it needs to be understood as a basic common sense. In this paper, we developed an unplugged activity to understand the PageRank algorithm which is closely related to the web. The experimental results show that our unplugged activities behave similarly to the PageRank algorithm.

  • IC-implementations provide high performance for solving the high computational cost of pattern matching but have relative low flexibility for satisfying different applications. In this paper, we report an associative memory architecture for k nearest neighbor (KNN) search, which is one of the most basic algorithms in pattern matching. The designed architecture features reconfigurable vector-component parallelism enabled by programmable switching circuits between vector components, and a dedicated majority vote circuit. In addition, the main time-consuming part of KNN is solved by a clock mapping concept based weighted frequency dividers that drastically reduce the in principle exponential increase of the worst-case search-clock number with the bit width of vector components to only a linear increase. A test chip in 180 nm CMOS technology, which has 32 rows, 8 parallel 8-bit vector-components in each row, consumes altogether in peak 61.4 mW and only 11.9 mW for nearest squared Euclidean distance search (at 45.58 MHz and 1.8 V).

  • Studies for structure design has conducted in many research institutions. A basic concept of Performance-Based Design for structures was presented in seismic fields. Hereafter, Demand were defined to communicate owner's demand to designer by several research institution. Performance-Based Design is guaranteed by an accurate analysis from hazard affected to structures and from social, economical and environmental effects. It is essential to define Performance Level and Performance Objective to grasp accurate demand for structures. In this study, Performance Level and Performance Objective in ATC-40, FEMA-273 and Eurocode were defined to introduce Performance-Based Design.

  • Objectives Although the word Zheng (證) is widely used basic term in nowaday's East Asian traditional medicine, it's definition can't be found in ancient texts before 20th century, and the history in which that term got general meaning in public, have not been clearly introduced. So the present author show the way Zheng confirm it's modern implication. Methods To search the books that contain any contents on Zheng's definition, the author mainly used the electronic texts of Super Star Reader (超星閱讀器). To search modern study article on Zheng's definition, the author used China National Knowledge Infrastructure (www.cnki.net). Results The present study shows that : although Treatments according to disease Pattern Identification (辨證施治) have been prominent treatment modality in East Asian traditional medicine, the general definition of disease Pattern (證) was given in late 20th century. Especially from 1955 to 1965, some major scholars like Ren Ying Qiu (任應秋), Zhu Yan (朱顔), Qin Bo Wei (秦伯未) and Jiang Jian Fu (蔣見復) did important roles in it's concept creation. Conclusions Modern concept of Zheng (證) was defined in late 20th century.

  • Power automation system to operate power distribution systems can be distinguished by distribution SCADA with remote monitoring and control; and distribution automation system with basic functions such as service restoration to the distribution SCADA; and distribution management system which is operated by various applications in order to enhance distribution system operation performance based on the distribution automation system. In the technological change, a technical boundary of information technology (IT) and operation technology (OT) is being blurred by that new concepts such as interoperability. In addtion, IT/OT convergence has been proposed by the improvement of ICT and power system technology. At the viewpoint, advanced distribution management system (ADMS) to have the new concepts and to increase distribution system operation efficiency through global information and functions from the other systems has been proposed. In order to implement the ADMS, IT and OT have to be employed together on the ADMS; and the concept-based IT/OT convergence concept has been presented. Therefore, this paper introduces ADMS and IT/OT convergence and proposes a design of IT/OT convergence based ADMS system design with configurations and functions.

  • This study is intended to create a tool which can identify the concept of consumption life level and to develop a standardized scale to measure consumption life level. Based on it, the concept and perspective of consumption life level was formed and then the scale for measuring it was developed. To develop the scale, the scale was firstly formed by extracting questions through a literature survey, and verifying validity through experts' opinions. Then the final scale was developed by conducting a questionnaire survey for consumers. A preliminary 27-item scale was developed through a literature review. 1000 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying academic data on the consumer's consumption life level but also understanding the consumer's basic behavior patterns. Then a series of tests: test-retest, item-to-total correlation, and Cronbach's reliability coefficient and factor analysis were conducted using the survey data and the final 20-item scale was constructed in the end. The consumer's consumption life level scale consisted of 4 factors.
