인간과 컴퓨터간의 상호작용에 있어서 감정처리는 매우 중요한 부결이다. 특히, 비디오 정보처리에 있어서 사용자의 감정을 처리할 수 있다면 비디오 검색이나 요약본 추출 등 다양한 응용분야에 활용이 가능하다. 비디오 데이터로부터 이러한 감정 처리를 하기 위해서는 감정에 관련된 특징들을 표현하고, 검출하는 것이 필요하다. 쉽게 추출이 가능한 색상이나 모션 등의 저급 특징들로부터 고급 개념인 감정을 검출하는 것은 매우 어려운 일이지만, 감정에 관련된 여러 장면으로부터 LDA(Linear Discriminant Analysis)와 같은 통계적인 분석을 통해 감정에 관련된 특징들을 검출하는 것은 가능하다. 본 논문에서는 색상, 모션 및 셧 길이 정보로부터 감정과의 관련된 특징을 표현하고 검출하는 방법을 제안한다. 제안된 특징을 사용하여 감정 검출에 관련된 실험을 한 결과 바람직한 결과를 얻었다.

Synchronous wind-induced pressures, measured in wind-tunnel tests on model buildings instrumented with hundreds of pressure taps, are an invaluable resource for designing safe buildings efficiently. They enable a much more detailed, accurate representation of the forces and moments that drive engineering design than conventional tables and graphs do. However, the very large volumes of data that such tests typically generate pose a challenge to their widespread use in practice. This paper explains how a wavelet representation for the time series of pressure measurements acquired at each tap can be used to compress the data drastically while preserving those features that are most influential for design, and also how it enables incremental data transmission, adaptable to the accuracy needs of each particular application. The loss incurred in such compression is tunable and known. Compression rates as high as 90% induce distortions that are statistically indistinguishable from the intrinsic variability of wind-tunnel testing, which we gauge based on an unusually large collection of replicated tests done under the same wind-tunnel conditions.

Abstraction applied in computer networking hides network details behind a well-defined representation by building a model that captures an essential aspect of the network system. Two current methods of representation are available, one based on graph theory, where a network node is reduced to a point in a graph, and the other the use of non-methodological iconic depictions such as human heads, walls, towers or computer racks. In this paper, we adopt an abstract representation methodology, the thinging machine (TM), proposed in software engineering to model computer networks. TM defines a single coherent network architecture and topology that is constituted from only five generic actions with two types of arrows. Without loss of generality, this paper applies TM to model the area of network monitoring in packet-mode transmission. Complex network documents are difficult to maintain and are not guaranteed to mirror actual situations. Network monitoring is constant monitoring for and alerting of malfunctions, failures, stoppages or suspicious activities in a network system. Current monitoring systems are built on ad hoc descriptions that lack systemization. The TM model of monitoring presents a theoretical foundation integrated with events and behavior descriptions. To investigate TM modeling's feasibility, we apply it to an existing computer network in a Kuwaiti enterprise to create an integrated network system that includes hardware, software and communication facilities. The final specifications point to TM modeling's viability in the computer networking field.

Compared with other philosophers and writers who were engaged in architecture Georges Bataille was extraordinary. Because he produced anti-architectural discourse. This paper studied the Bataille's thinking with relation to architecture that used as a fundamental and privileged metaphor. Philosophy regarded as the foundation of all academic discipline needed architecture in order to show its system was durable, synthetic and hierarchical. The will to build a solid system of reasoning made philosophy to call architecture to pretend that it is structurally stable. Metaphor and representation is inevitable in philosophy. Then architectural image that supported by discourse of philosophy became a representation of sociocultural system. According to Bataille architectural representation justified existing power and belief system. With architecture Identity always represented the true and good. This kind of architectonic thinking erased the Other that allowed metaphysics and symbolic Against architecture Bataille produced writings of violation and excess corresponding to labyrinth. Labyrinth in fact made a formal structure of architecture possible to be a metaphor of symbolic system. Bataille's anti-architectural thinking paradoxically shows the importance of Architecture and give a chance to rethink the ethical aspect of architecture instead of aesthetics.

Despite repeated exhortation about the importance of social and human dimensions of systems development, socio-organizational issues continue to be neglected and ignored in the current information systems practice. A review of the human information processing literature suggests that the reasons for this continuing lack of attention to social issues may be found in the limitations of human cognition and information processing capacities. Bostrom and Heinen(1978) and Kumar and Bjorn-Anderson(1990) also suggest that the inadequate attention to social problems and issues by the analyst could originate from the analysts limited problem perception. This research explores how the representation forms of information systems(IS) methodology used in understanding and modeling the problem situation affect such systems development problem perception. Typically, a system development methodology prescribes the use of system models(i.e., system representations) to understand, analyze, evaluate, and design the information system. Given the size and complexity of information systems, and the abstraction and simplification underlying the modeling process, system representations usually depict only a limited set of aspects of the system. Thus, a methodology whose representations are limited to technical aspects will tend to limit the analyst's perspective to a technical one only(Kumar & Welke, 1990). Following the same line of argument, in contrast, it is the conjecture of this study that a methodology which specifies both social and technical aspects of IS development will help the analyst develop a more comprehensive view of the IS problem domain. Based on the above concept, a theoretical model was first developed which explained the systems analysts cognitive process. Drawing on this model, a research model was developed hypothesizing the impacts of representation forms on problem identification. The model was tested using a laboratory experiment with 70 individual subjects. A special computer software was developed with a hypermedia authoring tool to conduct the experiments in order to avoid experimenter biases and to maintain consistency in administrating repeated experiments. The program, designed to replace the experimenter, consisted of functions such as presenting the subjects with problem material, asking the subjects questions, and saving the typed answers of the subjects. The results indicate that representation forms strongly influence problem identification. It was found that the use of the socio-technical representation form led to the findings of more social problems than the use of technical representation form. The results imply significant effects of representation forms on problem findings and also suggest that the use of adequate representation forms may help overcome dysfunctional effects of our limited information processing capacity.

본 연구는 국민참여재판의 평결범주가 일반인의 법적판단에 미치는 영향과 그 과정에서 '무죄표상'의 역할을 확인하였다. '무죄표상'은 일반적인 의미의 무죄(잘못이 없음)판단을 위한 심리적 기준을 의미한다. 또한, 법률로 정해진 유죄판단 기준으로 간주되는 '합리적 의심의 여지없는 유죄의 증명(beyond a reasonable doubt: BRD)'과 개인의 역치에 대한 추정치인 IT(individual threshold)의 역치로서의 기능을 비교하였다. 본 연구는 평결범주(유죄/무죄 vs. 유죄/유죄아님)와 피고인 유죄가능성(낮음 vs. 높음)을 각각 두 수준으로 조작한 2×2 완전교차요인설계를 사용하였으며, 온라인으로 진행되는 실험에 자발적으로 참여한 137명의 자료가 분석에 사용되었다. 실험은 '무죄표상' 및 기소유죄확률 측정, 재판시나리오 제시, 피고인에 대한 법적판단(판단 확신감 및 피고인 유죄가능성 추정 등 포함) 순으로 진행되었다. 연구 결과, 평결범주는 일반인의 법적판단에 유의한 영향을 미치지 못하는 것으로 나타났으나 '유죄/무죄'의 평결범주를 제시받은 경우 '유죄/유죄아님'의 평결범주를 제시받은 경우보다 유죄판단 비율이 높은 경향이 있었다. 일반인들의 '무죄표상'과 평결범주의 상호작용은 이론적 유죄판단 역치(BRD)와 개인의 역치(IT)의 차이(역치 변화량)를 잘 예측하는 것으로 나타났으며, '유죄/무죄'의 평결범주를 제시받은 경우에 '유죄/유죄아님'의 평결범주를 제시받은 경우보다 '무죄표상'의 변화에 따른 역치변화량이 더 컸다. 역치로서의 BRD와 IT를 비교한 결과에서는 IT가 유죄가능성과 상호작용하여 일반인의 법적판단을 유의하게(p<.1) 예측하는 것으로 나타나서 IT가 BRD보다 더 좋은 역치 추정치라고 할 수 있었다. 본 연구는 법률가들 사이에서 종종 제기되는 문제인 국민참여재판 평결범주의 효과를 실험을 통하여 확인하고 그 효과의 심리적 기제에 대한 논리적인 추론 및 경험적 근거를 제공하였다는 데 의의가 있다.

Let K be a number field and fix a prime number $p$. For any set S of primes of K, we here say that an elliptic curve E over K has S-reduction if E has bad reduction only at the primes of S. There exists the set $B_{K,p}$ of primes of K satisfying that any elliptic curve over K with $B_{K,p}$-reduction has no $p$-torsion points under certain conditions. The first aim of this paper is to construct elliptic curves over K with $B_{K,p}$-reduction and a $p$-torsion point. The action of the absolute Galois group on the $p$-torsion subgroup of E gives its associated Galois representation $\bar{\rho}_{E,p}$ modulo $p$. We also study the irreducibility and surjectivity of $\bar{\rho}_{E,p}$ for semistable elliptic curves with $B_{K,p}$-reduction.
