The relationship between civic attitudes and voting intention : an analysis of vocational upper secondary schools in England and Singapore
No full textFrom 2009 to 2011, a team from the Centre for Learning and Life Chances in Knowledge Economies and Societies carried out a mixedmethods study of young people in England and Singapore. With regard to civic attitudes, the study showed that there was a greater sense of political self-efficacy and collective (school) efficacy in Singapore than in England. In addition, the group in Singapore scored higher on future voting relative to the group in England. Further, while both political self-efficacy and collective (school) efficacy were correlated with future voting in England, only the latter was correlated in the case of Singapore. For some, the results may seem counter-intuitive. The article reflects on these results, particularly those relating to democratic outcomes
Development of temperature-robust damage factor based on sensor fusion for a wind turbine structure
No full textWind power systems have gained much attention due to the relatively high reliability, maturity in technology and cost competitiveness compared to other renewable alternatives. Advances have been made to increase the power efficiency of the wind turbines while less attention has been focused on structural integrity assessment of the structural systems. Vibration-based damage detection has widely been researched to identify damages on a structure based on change in dynamic characteristics. Widely spread methods are natural frequency-based, mode shape-based, and curvature mode shape-based methods. The natural frequency-based methods are convenient but vulnerable to environmental temperature variation which degrades damage detection capability; mode shapes are less influenced by temperature variation and able to locate damage but requires extensive sensor instrumentation which is costly and vulnerable to signal noises. This study proposes novelty of damage factor based on sensor fusion to exclude effect of temperature variation. The combined use of an accelerometer and an inclinometer was considered and damage factor was defined as a change in relationship between those two measurements. The advantages of the proposed method are: 1) requirement of small number of sensor, 2) robustness to change in temperature and signal noise and 3) ability to roughly locate damage. Validation of the proposed method is carried out through numerical simulation on a simplified 5 MW wind turbine model.close
The establishment of Eunpasango(恩坡散稿) and Sim No-sung(沈魯崇)
No full textEunpasango(恩坡散稿) is an anthology of manuscript copies of the works of Sim Nak-su(沈樂洙, 1739~1799). It is held by the Kyujanggak Institute for Korean Studies and the C.V. Starr East Asian Library of UC Berkeley. Thus far, Sim Nak-su has been known more as a politician than as a man of letters. This study explores the reasons why Sim Nak-sus literary works deserve academic attention by attempting to conduct a comprehensive bibliographic analysis of Eunpasango.
This study adopted two methodological approaches. First, it took a positivist approach relying on primary sources. The study compared the four versions of extant Eunpasango manuscripts to determine the relationship between each manuscript copies. The study also compared the draft copy with each of the subsequent revised versions of the manuscript, and reconstructed the process of revision.
Secondly, this study tried to conduct the bibliographic analysis with a view to literary/historical contexts. As a result, this study found how Sim No-sung(沈魯崇, 1762~1837) was dedicated to the restoration of the literary legacy of his father, Sim Nak-su, and how the publication of Eunpasango had been the focus of Sim No-sungs efforts throught his life.
This study is a step toward illuminating the internal origin of Sim No-sungs literature. Further research on the literary works of Sim Nak-su needs to be conducted, especially by placing the literature Sim Nak-su and Sim No-sung within the framework of inter-generational diachronic compariso

techniques, undertook basic research, was passionate about education in the early years of neurosurgery in Korea, and
played an essential role in founding the Korean Neurosurgical Society. Sim was a true neurosurgeon—a teacher, a scientist,
and a superb pioneer in Korean neurosurgery
Agent-Based Cloud Computing
No full textAgent-based cloud computing is concerned with the design and development of software agents for bolstering cloud service
discovery, service negotiation, and service composition. The significance of this work is introducing an agent-based paradigm for
constructing software tools and testbeds for cloud resource management. The novel contributions of this work include: 1) developing
Cloudle: an agent-based search engine for cloud service discovery, 2) showing that agent-based negotiation mechanisms can be
effectively adopted for bolstering cloud service negotiation and cloud commerce, and 3) showing that agent-based cooperative problemsolving
techniques can be effectively adopted for automating cloud service composition. Cloudle consists of 1) a service discovery agent
that consults a cloud ontology for determining the similarities between providers’ service specifications and consumers’ service
requirements, and 2) multiple cloud crawlers for building its database of services. Cloudle supports three types of reasoning: similarity
reasoning, compatibility reasoning, and numerical reasoning. To support cloud commerce, this work devised a complex cloud
negotiation mechanism that supports parallel negotiation activities in interrelated markets: a cloud service market between consumer
agents and broker agents, and multiple cloud resource markets between broker agents and provider agents. Empirical results show that
using the complex cloud negotiation mechanism, agents achieved high utilities and high success rates in negotiating for cloud resources.
To automate cloud service composition, agents in this work adopt a focused selection contract net protocol (FSCNP) for dynamically
selecting cloud services and use service capability tables (SCTs) to record the list of cloud agents and their services. Empirical results
show that using FSCNP and SCTs, agents can successfully compose cloud services by autonomously selecting services
Chi-Sung's Contribution to Sung-hsiao（宋学）: Especially on his "Fei-han"
No full textChi-Sung (契嵩), a Buddhist priest of Sham-sect (禅宗) in the era of Sung (宋), was also a learned Confucian scholar. His "Fei-han (非韓)" was written to criticize the anti-Buddhistic views of Han-Yu (韓愈), -a noted Confucian scholar in the era of Tang (唐), - which are to be observed in his "Yuan-tao (原道)" and other writings. The author of this article intends, through the examination of Chi-Sung's opinions on "Chung-yang (中庸)" and "Chou-i (周易)", to see how and in what respect his new points of view influenced his contemporary Confucian scholars and, influencing them, contributed to the formation of new sect of learning in the era of Sung.Article信州大学文理学部紀要. 第1部, 人文・社会 9: 49-59(1960)departmental bulletin pape
Optimization of critical factors affecting the performance of an allergen chip for the analysis of an allergen-specific human IgE in serum
No full textA sensitive and multiplexed assay of allergen-specific human immunoglobulin E (IgE) is of great significance in the precise diagnosis of allergies. We report on the optimization of critical factors for chip-based analysis of IgE in human serum with a high reliability. Extracts of two mite species were used as model allergens, and were spotted onto a glass slide for the construction of an allergen chip. Respective allergen-specific IgE in human serum was analyzed by using biotinylated anti-human IgE and a streptavidin-Cy3 conjugate. Factors affecting the performance of the allergen chip were investigated and optimized. Especially, the effect of additives, the concentrations of biotinylated anti-human IgE and the streptavidin-Cy3 conjugate, the serum dilution factor, and the concentration of allergen extract as a capturing agent were examined in detail. Under the optimized conditions, a chip-based analysis for sera from 43 patients revealed a reliable and reproducible diagnosis of respective allergies, showing a good correlation with a conventional CAP assay
Decentralized Strategies for Monitoring Structures using Wireless Smart Sensor Networks
No full textDriven by the needs to address problems with our rapidly aging civil infrastructure, structural health monitoring (SHM) has arisen as an important tool to improve maintenance and operation. Introduced as a promising alternative to the traditional wired sensors, wireless smart sensors offer unique features (low cost, wireless communication, onboard computation, and small size) that enable deployment of dense array of sensors essential for assessing structural damage. The centralized data collection approach, which the wired sensor system commonly employs, is not suitable to wireless smart sensor networks (WSSNs) due to limitations in the wireless communication; decentralized data aggregation and processing is required in the WSSNs. Rather than collecting uncondensed raw sensor data at a centralized location, in-network data processing, made possible by the onboard computational capability of smart sensors, is utilized to condense the raw data and extract meaningful information. By transferring only the condensed data to the centralized location, data communication over the wireless links can be greatly reduced. Decentralized data aggregation approaches can be placed in two broad categories: (a) independent processing (each node processes sensor data independently), and (b) coordinated processing (sensor nodes collaborate to process sensor data by sharing information). This report outlines the implementation of both decentralized data aggregation approaches for the WSSNs employing Crossbow’s Imote2 smart sensor platform. Design considerations for developing WSSN applications are described herein, including network-wide flow and timing, fault-tolerant feature, and network topology to account for the decentralized data aggregation. WSSN applications introduced in this report can be downloaded at the Illinois SHM Project website (http://shm.cs.uiuc.edu).Submitted by Sung Han Sim ([email protected]) on 2009-11-21T21:39:22Z
