  • This study investigated the complex meanings of the concept of place and their periodical changes in the Korean architectural discourse. For that, the study surveyed almost every articles in majour 3 Korean architectural magazines during around 1990s, when the Korean architects and theorists concerned the 'place' as an alternative of the modernists' 'space'. 60 selected articles were organized in a table in a chronological order together with their keywords and category codes. The 8 categories reflecting 8 issues of 'place' were suggested in the study after the analysis of selected articles' contents. The categories were structured by two axes which were 4-grade scale axis influences by C. Norberg-Schultz' approach, and 'architecture-human' axis following the 'structure-action' division by A. Giddens. After the analysis of the diachronic and synchronic tables, the study tried to establish a structure model of the concept of place in Korean architectural context, which consisted of architectural terms such as environment, social system, context, identity, landscape, community, Materiality, and residence. This final result could be useful for both architects and theorists who might try to apply the idea of 'place' without erstwhile confusion on their design or research by examining the detailed contents of the concept.

  • H.264, a recently proposed international video coding standard, has adopted context-based adaptive variable length coding (CAVLC) as the entropy coding tool in the baseline profile. By combining an adaptive variable length coding technique with context modeling, we can achieve a high degree of redundancy reduction. However, CAVLC in H.264 has weakness that the correct prediction rate of the variable length coding (VLC) table is low in a complex area, such as the boundary of an object. In this paper, we propose a VLC table prediction scheme considering multiple reference blocks; the same position block of the previous frame and the neighboring blocks of the current frame. The proposed algorithm obtains the new weighting values considering correctness of the VLC table for each reference block. Using this method, we can enhance the prediction rate of the VLC table and reduce the bit-rate.

  • The purpose of this essay is threefold. First, to highlight research of Seonmin KIM, whose 2006 Ph.D. dissertation elucidates complex relationships among Ming China, Choson Korea, Tokugawa Japan, and mountainous ginseng-producing "borderlands" between Korea and China; her story concludes with the remarkable rise of a borderlands power that overthrew Ming China, there-by establishing dominance that lasted into the $20^{th}$ century - the Qing Dynasty. A second purpose is to showcase application of a non-standard-model - the Hydraulic Metaphor - that elucidates economic components of Professor KIM's history via visual and intuitive mechanisms designed to be understandable for non-specialists. Last, an outline of East Asian history is placed within context of centuries of monetary evolution that eventually yielded the late-$16^{th}$-century birth of globalization.

  • An environment in which the software is operated become more complex and changed dynamically. Such software requires the ability to adapt in accordance with operating environments, by monitoring the changes of user requirements and operating environments. Especially, the mobile device used in military operation requires more dynamical adaptation than the mobile device in normal environment. In this paper, we propose MOSAIC architecture based on Self-Adaptive Software suitable for military mobile device and verify the results. The proposed architecture consists of context manager, evaluation manager and adaptation manager. We simulate the MOSAIC architecture by modelling PRE(Position Reporting Equipment) used in the army and verify four types of operational mode and dynamical reconfiguration of user interface.

  • Today's computers are built up from a minimal set of standard pattern recognition operations. Logic gates, such as NAND, are common examples. Biomolecular materials offer an alternative approach, both in terms of variety and context sensitivity. Enzymes, the basic switching elements in biological cells, are notable for their ability to discriminate specific molecules in a complex background and to do so in a manner that is sensitive to particular milieu features and indifferent to others, The enzyme, in effect, is a powerful context sensitivity pattern processor that in a rough way can be analogized to a neuron whose input-output behavior is controlled by enzymatic dynamics.

  • Present computing power and enhanced technology is progressing at a dramatic rate. These systems can unravel complex issues, assess and control processes, learn, and-in many cases-fully automate production. There is no doubt that technological advancement is improving many aspects of life, changing the landscape of virtually all industries and enhancing production beyond what was thought possible. However, the human is still a part of these systems. Consequently, as the advancement of systems transpires, the role of humans within those systems will unavoidably continue to adapt as well. Due to the human tendency for error, this technological advancement should compel a persistent emphasis on human error reduction as part of maximizing system efficiency and safety-especially in the context of the nuclear industry. Within this context, as new systems are designed and the role of the human is transformed, human error should be targeted for a significant decrease relative to predecessor systems and an equivalent increase in system stability and safety. This article contends that optimizing the roles of humans and machines in the design and implementation of new types of automation in nuclear facility systems should involve human error reduction without ignoring the essential importance of human interaction within those systems.

  • The classical HMM is defined by a parameter triple �� = (��, A, B), where each parameter represents a collection of probability distributions: initial state, state transition and output distributions in order. This paper proposes a new stationary parameter e = (e1, e2, …, eN) where N is the number of states and et = P(|xt = i, y) for describing how an input pattern y ends in state xt = i at time t followed by nothing. It is often said that all is well that ends well. We argue here that all should end well. The paper sets the framework for the theory and presents an efficient inference and training algorithms based on dynamic programming and expectation-maximization. The proposed model is applicable to analyzing any sequential data with two or more finite segmental patterns are concatenated, each forming a context to its neighbors. Experiments on online Hangul handwriting characters have proven the effect of the proposed augmentation in terms of highly intuitive segmentation as well as recognition performance and 13.2% error rate reduction.

  • 스마트 폰을 비롯한 다양한 모바일 기기는 사용자 중심의 정보 수집과 상황 인지 및 서비스 제공에 적합한 환경이다. 하지만 사용자에게 의미 있는 서비스를 제공하기 위해서는 단순한 환경 상태 또는 행동에 대한 추론보다는 사용자의 행동에 대한 목적과 의도를 파악할 수 있어야 한다. 즉, 주변 환경 상태와 사용자의 행동 이력, 현재의 행동 등을 종합하여 사용자가 필요로 하는 서비스를 예측하고 결정할 수 있는 상황 모델이 필요하다. 따라서 본 논문에서는 사용자의 일상 생활 상에서의 중요한 일정을 추적하여 적합한 모바일 서비스를 제공하기 위한 기반 지식 모델로서 계층적인 모바일 컨텍스트 모델을 제안하고자 한다. 기존의 상-하위 컨텍스트 모델을 세분화하고 의미 있는 컨텍스트를 추가하여 서비스를 결정하는데 중요한 기반 정보로 활용될 수 있도록 한다.

  • Trusted Execution Environment(TEE) is an execution environment provided by CPU hardware to gain guarantee that the execution context is as expected by the execution requester. Remote attestation of the execution context naturally arises from the concept of TEEs. Many implementations of TEEs use cryptographic remote attestation methods. Though the implementation of attestation may be simple, the implementation of verification may be very complex and heavy. By using a server delegating the verification process of attestation information, one may produce lightweight binaries that may verify peers and establish a secure channel with verified peers.

  • The growth-share matrix is a portfolio planning tool developed by the Boston Consulting Group (BCG) to assist competitive positioning in the international market including those in the construction industry. This matrix is helpful in balancing the firm's cash-flow, and it can suggest strategic directions for each business unit. However, its effectiveness and applicability have long been debated in the academic field due to the complex and unique industrial context of construction. To solve the dispute, this research clarifies the applicability of theories underlying the growth-share matrix to the construction industry. Empirical research based on actual financial data of Korean construction firms is adopted for the statistical analysis including one-way analysis of variance and correlation analysis. The results of this research show that empirical findings on the relationship between performance variables. In this context, this research can provide important insights on the concept of portfolio management in the construction industry.
