A bubble diagram is understood as a graphic medium which bridges program and plan in architectural design process. The role of a bubble diagram is either to generate or to explain a plan in relation to its program. Despite the explicit role of a bubble diagram in architectural design process, what a bubble diagram indicates exactly is very ambiguous. Here I attempt to reveal the nature of the bubble diagram more sharply. My main argument is that the ambiguity of a bubble diagram results from the fact that it is used to range two different types of representational formats. Reviewing the theories of shape recognition and shape representations in vision science, I will also argue that the procedural description of architectural design process should be criticized and that the focus of design method research has to be shifted into the representational format of form description in architectural design process.

This paper describes the surface form measurement of a spherical smooth surface by using single shot off-axis Fizeau interferometry. The demodulated phase map is obtained and unwrapped to remove the $2\pi$ ambiguity. The unwrapped phase map is converted to height and the 3D surface height of the surface object is reconstructed. The results extracted from the single shot off-axis geometry are compared with the results extracted from four-frame phase shifting in-line interferometry, and the results are in excellent agreement.

Morphologically annotated corpora are the basis for many tasks of computational linguistics. Most current approaches use statistically driven methods of morphological analysis, that provide just POS-tags. While this is sufficient for some applications, a rule-based full morphological analysis also yielding lemmatization and segmentation is needed for many others. This work thus aims at 〔1〕 introducing a rule-based Korean morphological analyzer called Kormoran based on the principle of linearity that prohibits any combination of left-to-right or right-to-left analysis or backtracking and then at 〔2〕 showing how it on be used as a POS-tagger by adopting an ordinary technique of preprocessing and also by filtering out irrelevant morpho-syntactic information in analyzed feature structures. It is shown that, besides providing a basis for subsequent syntactic or semantic processing, full morphological analyzers like Kormoran have the greater power of resolving ambiguities than simple POS-taggers. The focus of our present analysis is on Korean text.

This study is regarding closed and open forms, which have relatively high recognition among visual perception phenomena in costumes. In particular, this study reviewed closeness and openness of ethnic look, which is a representative open costume. Closed form can be summarized as simple and clear silhouette, conspicuous differentiation from the background, simple construction of the costume and colors with low brightness and clearness. It Is modern, functional, rational and modest. On the other hand, open form can be summarized as complicated and inconspicuous edge line, complicated inner shape and colors with high brightness, high clearness and vividness. It includes concepts of pleasure, entertainment, joy, eroticism, rebel and resistance. Modern costumes have been simplified for a long time and they have functional and closed characteristics in their shape, structure and form. On the other hand, modern open form costumes are usually found in sub-cultural styles such as punk, hippie, kitsch and vintage, and some ethnic looks. Following is a summary of the characteristics of open form shown in the ethnic look. 1. The shape, structure of costumes, hair accessories, lace, ruffle and ornaments are complicated and irregular. 2. The silhouette is inconspicuous because of ambiguity between backgrounds and ABC (Apparel-Body-Construct) or the use of see-through materials. 3. It makes complicated visual shapes because it does not have a single type but is composed of various clothing items together. 4. It gives complex feelings by matching various colors or more than two different fabrics. 5. It looks like the open type because of the complex patterns shown in the costumes.

This paper aims to define the relational logic of in-between code articles as well as within atomic sentences in Korean Building Code, as an intermediate research and development process for the automated building permit system of Korea. The approach depicted in this paper enables the software developers to figure out the logical relations in order to compose KBimCode and its databases. KBimCode is a computer-readable form of Korean Building Code sentences based on a logic rule-based mechanism. Two types of relational logic definition are described in this paper. First type is a logic definition of relation between code sentences. Due to the complexity of Korean Building code structure that consists of decree, regulation or ordinance, an intensive analysis of sentence relations has been performed. Code sentences have a relation based on delegation or reference each other. Another type is a relational logic definition in a code sentence based on translated atomic sentence(TAS) which is an explicit form of atomic sentence(AS). The analysis has been performed because the natural language has intrinsic ambiguity which hinders interpreting embedded meaning of Building Code. Thus, both analyses have been conducted for capturing accurate meaning of building permit-related requirements as a part of the logic rule-based mechanism.

한글 입력 방식은 어떤 형태이건 기본 낱자들에 대한 글쇠배열과 결합 규칙이라는 두 요소를 반드시 가진다. 그런데 그 규칙을 토대로 입력 방식을 실제로 구현해 보면, 기본 낱자가 여럿 모인 복합 낱자를 입력할 때 모호성이 존재하거나 다음 글자의 연속 입력이 되지 않는 식의 문제가 발생할 수 있다. 한글은 모아쓰기라는 특성으로 인해 낱자 경계와 글자 경계라는 보이지 않는 정보가 입력 과정에서 추가로 고려되어야하기 때문이다. 초성과 종성을 문맥에 따라 구분해야 하는 두벌식, 글쇠가 매우 적은 모바일 환경, 수십 종류의 낱자들을 조합해야 하는 옛한글이라는 조건이 더해지면 입력 방식을 기술하고 분석하는 난이도가 더욱 높아진다. 본 논문에서는 한글 입력 방식에서 쓰이는 낱자의 결합 규칙을 대결합과 소결합으로 구분해서 기술하는 체계를 제안하며, 이를 토대로 어떤 입력 방식이 주어졌을 때 복합 낱자를 입력하는 세부 규칙을 생성하고 예상되는 문제점을 자동으로 분석해 주는 도구 프로그램을 소개하였다. 그리고 모바일용 삼성 천지인과 KT나랏글 한글 입력 방식을 실제로 분석한 결과를 제시하였다.

How to choose defaults in risk-informed regulations depends on the conservatism implicated in regulatory defaults. Without a universal agreement on the approaches dealing with the conservatism of defaults, however, the desirability of conservatism in regulatory risk analyses has long been controversial. The opponent views it as needlessly costly and irrational, and the proponent as a form of protection against possible omissions or underestimation of risks. Moreover, the inherent ambiguity of risk makes it difficult to set suitable defaults in terms of risk. This paper, the extension of the previous work [1], focuses on the effects of different levels of conservatism implicated in regulatory defaults on the estimates of risk. According to the postulated behaviors of regulated parties and the diversity of interests of regulators, in particular, various measures for evaluating the effect of conservatism in defaults are developed and their properties are explored. In addition, a simple decision model for setting regulatory defaults is formulated, based on the understanding of the effect of conservatism implicated in them. It can help decision makers evaluate the levels of safety likely to result from their regulatory policies.

This paper presents the efficient algorithms for the pose determination of a circular object with and without a priori knowledge of the object radius. The developed algorithms valid for a circular object are the result of the elaboration of Ma's work [2], which determines the pose of a conic object from two perspective views. First, the geometric constraint of a circular object and its projection on the image plane of a camera is described. The number of perspective views required for the object pose determination with and without a priori knowledge of the object radius is also discussed. Second, with a priori knowledge of the object radius, the pose of a circular object is determined from a single perspective view. The object pose information, expressed by two surface normal vectors and one position vector, is given in a closed form and with no ambiguity. Third, without a priori knowledge of the object radius, the pose of a circular object is determined from two perspective views. While the surface normal vectors are obtained from the first view, the position vector is obtained from the two views.

^x This paper focuses on clarifying the diverse conceptions of landscape, of which ambiguity gives rise to confusion to the theory and practice of landscape architecture. Landscape in the form of landscipe has once indicated land, a defined space or a humanized environment, cultivated and inhabited for the purpose of biological sustenance of ordinary people. With the advent of landschap(landscape) painting, its concept moved from the real world to the scenery, a prospect, 'a portion of earth's surface that can be seen at once by a man who is himself upon the surface. 'Once appeared, it remained as a central concept until the 19th century when the modern land-scape architecture, which claims to stand for the democratic planning and environmental design, emerged. However, it still survives as the most popular concept :a landscape is a man-made, beautiful scene. To the contrary, the geographers hold that a landscape is not an actual scene viewed by a particular observer, but is a generalization induced from the observation of many individual scene. Since it is not only very attractive to the general public, but also very important to the designers, scholars and artists, operational definitions of landscape are urgently needed.

A Bayesian response surface updating procedure is applied in order to update the parameters of the covariance function of a random field for concrete properties based on a limited number of available measurements. Formulas as well as a numerical algorithm are presented in order to update the parameters of response surfaces using Markov Chain Monte Carlo simulations. The parameters of the covariance function are often based on some kind of expert judgment due the lack of sufficient measurement data. However, a Bayesian updating technique enables to estimate the parameters of the covariance function more rigorously and with less ambiguity. Prior information can be incorporated in the form of vague or informative priors. The proposed estimation procedure is evaluated through numerical simulations and compared to the commonly used least square method.
