In this paper, we propose an efficient memory architecture for coeff_token encoding in H.264/AVC standard. The VLCTs used to encode the coeff_token syntax element are implemented with the memory. In general, the size of memory must be reduced because it affects the cost and operation speed of the system. Based on the analysis for the codewords in VLCTs, new memory architecture is designed in this paper. The proposed memory architecture results in about 24% memory saving, compared to the conventional memory architecture.

In architectural planning, previous cases of similar spatial program provide important data for architectural design. Case-based reasoning (CBR) paradigm in the field of architectural design is closely related to the designing behavior of a planner who makes use of similar architectural designs and spatial programs in the past. In CBR, spatial graph can be constituted with most fundamental data, which can provide a method of searching spatial program by using visual graphs. This study developed a system for CBR that can analyze the similarity through graph comparison and search for buildings. This is an integrated system that is able to compare space similarity of different buildings and analyze their types, in addition to the analysis on a space within a single structure.

Interrogative sentences are generally used to perform speech acts of directly asking a question or making a request, but they are also used to convey such speech acts indirectly. In the utterances, such indirect uses of interrogative sentences usually carry speaker's emotion with a negative attitude, which is close to an expression of anger. The identification of such negative emotion is known as a difficult problem that requires relevant information in syntax, semantics, discourse, pragmatics, and speech signals. In this paper, we argue that the interrogatives used for indirect speech acts could serve as a dominant marker for identifying the emotional attitudes, such as anger, as compared to other emotion-related markers, such as discourse markers, adverbial words, and syntactic markers. To support such an argument, we analyze the dialogues collected from the Korean soap operas, and examine individual or cooperative influences of the emotion-related markers on emotional realization. The user study shows that the interrogatives could be utilized as a promising device for emotion identification.

The impersonal or psyc-predicate construction in Old English (=OE) poses a special challenge for most case theories in generative linguistics. In the OE impersonal construction, the experiencer argument is marked by dative, accusative, or nominative, whereas the theme is marked by nominative, genitive, or accusative, or by a PP. The combinations of possible cases for experiencer and theme are not random, bringing about daunting complexity for possible and impossible case frames. In this paper, I develop a conceptual semantic case theory (a la Jackendoff 1990, 1997, 2002; Yip, Maling, and Jackendoff 1987) to provide a unified account for the complicated case frames of the OE impersonal construction. In the conceptual semantic case theory, syntax and semantics have their own independent case assignment principles. For impersonal verbs in OE, I propose that UG leave an option of determining either syntactic or semantic case to lexical items. This proposal opens a new window for the OE impersonal construction, in that it naturally explains both possible and impossible case frames of the construction.

Visual trope is one of the important appealing methods of creativity to induce voluntary consumer participation. In many cases, it delivers a message using metaphors. To define the concepts of_metaphor, we investigated methods of expression and significance of metaphor itself and associated forms; in all: metaphor, analogy, catachresis, metonymy, and synecdoche. We also considered the structure of each form to propose a method of metricizing the metaphor Consequently, we found that the metaphor of a visual trope is a type of operation and development of codes. We suggested models for each form type and concept of metaphor through the evaluation of metaphor significance and case study. Metaphor significance forms mutually close relationships with codes of pragmatics, semantics, and syntax. We suggested a type of metrics or a guideline for an expression method and evaluation of a visual trope appropriate for a metaphor form type. Therefore and importantly, the following study presents unique, but manifold results that are also useful in the field of design.

Today the Seoul metro has become the most important public transportation since opening in 1974. However, planning and design of stations, transfer systems and facilities are discorded by different companies and subway lines. Therefore, there is lack of objective design guidelines to secure legibility and safety in subway space. In this context, we aim to investigate the objective design and planing guidelines in terms of people's cognition and space use pattern. Space syntax method which enables scientific analysis is utilized to examine spatial layout considering passenger's spatial behavior. The research resulted in providing objective design and planning standards.

If normality of an observed data is not a viable assumption, we can carry out normal-theory analyses by suitable transforming data. Power transformation by Box and Cox, one of the transformation methods, is derived the power which maximized the likelihood function. But it doesn't induces the closed form in mathematical analysis. In this paper, we compose some R the syntax of which is easier than other statistical packages for deriving the power with using numerical methods. Also, by using R, we show the transformed data approximately distributed the normal through Q-Q plot in univariate and bivariate cases with some examples. Finally, we present the value of a goodness-of-fit statistic(AD) and its p-value for normal distribution. In the similar procedure, this method can be extended to more than bivariate case.

Uncertainty and dynamism surrounding pervasive systems require new and sophisticated approaches to defining, detecting, and handling complex exceptions. This is because the possible erroneous conditions in pervasive systems are more complicated than conditions found in traditional applications. We devised a novel exception description and detection mechanism based on "situation"- a novel extension of context, which allows programmers to devise their own handling routines targeting sophisticated exceptions. This paper introduces the syntax of a language support that empowers the expressiveness of exceptions and their handlers, and suggests an implementation algorithm with a straw man analysis of overhead.

한국어 문장은 하나 이상의 용언으로 인해 구문 분석 과정에서 다양한 구문 모호성이 발생한다. 이들 중 대부분은 내포문의 수식 범위로부터 발생되는 구 부착의 문제 때문이다. 이런 구운 모호성은 내포문의 범위를 정해서 하나의 구문 범주의 기능을 가지도록 하면 해결할 수가 있다. 본 논문에서는 내포문의 범위를 정하기 위해서 문형과 한국어의 구문 특성을 이용한다. 먼저, 내포문에 있는 용언의 문형 정보가 가질 수 있는 필수격을 최대로 부착하여 내포문의 범위를 정해서 단문으로 분할한다. 그리고 한국어의 구문 특성을 이용해서 분할된 내포문의 기능을 하나의 구문 범주인 체언구나 부사구로 변환한다. 이렇게 함으로써 복합문의 구성 형태가 단문 구조로 변환되기 때문에 내포문의 범위에 의한 구 부착의 문제가 쉽게 해결된다. 이것을 본 논문에서는 내포문의 단문 분할이라고 한다. 본 논문에서 제안한 방법으로 432 문장을 실험한 결과 문형과 단문 분할을 이용하지 않은 방범보다 구문모호성이 87.73% 감소되었다.

Negative polarity items(NPIs), which function as quantifiers are licensed in a syntactically strict way by negatives, which function as qualifiers, resulting in universal negating interpretations as pairs. We present a proposal to explain the related phenomena, in which the syntax and the semantics are closely related to each other, with Combinatory Categorial Grammar. For this purpose, we first adopt the usual approach to scrambling, but control its overgeneration with the use of markers, taking into account the complex syntactic phenomena involving NPIs and scrambling in Korean. We also propose to utilize polarity intensity as a novel feature, in order to account for the universal negating interpretations when NPIs are combined with negatives. Our proposal also explains the difference in readings when other quantifiers or qualifiers intervene the NPI and the related negatives.
