In our country, the application of the design method of face to face dimension in wall-slab apartment has passed 10 years. So MC(Modular Coordination) design method has fixed in the design step to some degree. In Design and Work Execution of House the exclusive area of the apartment was calculated by face to face dimension. And the term of face to face dimension was known broadly to clients, construction company, etc. But design method of face to face dimension is not to simply extend the room size so far as wall depth in design process but to ensure the actual space should be considered with efficient use and assembly of building components. That is to say, Design method of face to face dimension is not to be defined by design step but to be related with construction and maintenance. However in construction process the point of face to face design method was not understood even now. So the purpose of this study was to extract the effect and question of face to face design method in construction process by survey of actual condition of structure and construction quality, and compare this result with existing construction method. The following project of this study is to survey of actual condition of interior components such as gypsum board, windows & doors etc. Therefore this study is to induce architectural long-life through architectural standardization construction and component's exchange, and, by the subject of the study on Apartment to have design guideline and basis for joining part between Gypsumboard and windows.

디자인의 심미적 요인은 물리적, 기능적, 행태적, 경제적 요인에 비해 정량적으로 측정되거나 평가되기가 쉽지 않다. 그렇지만 심미적 요인들은 디자인 조형과정에서 필수적으로 중요한 역할을 한다. 이러한 중요성에도 불구하고 공간의 심미적 가치평가나 심미적 영향 요소들의 상호작용에 관한 연구는 미비한 편이다. 그래서 본 연구는 상업 공간디자인의 시각적 선호도와 지각적-인지적, 감정적 차원의 미적 변수들 사이의 상호관계를 찾아보고자 하였다. 실증 조사의 연구 결과에 따르면, 상업 공간디자인의 선호도에 긍정적 영향을 주는 미적 변수로는 지각적-인지적 차원의 '통일', '질서', '명료성'과 감정적 차원의 '기분 좋은', '편안한'을 들 수 있다. 반면, 선호도에 부정적 영향을 주는 미적 변수로는 지각적-인지적 차원의 '대비', 복잡성', 그리고 명료성의 반대 개념인 '불명료성'과 감정적 차원의 '호기심 있는', '긴장되는'을 들 수 있다.

The purpose of this study is to survey about the images of the sexy clothes that young women sympathize in modern society, that is, to make a research into the cognitive dimensions of 'Sexy image' and the constructive peculiarity of clothing. The researches into dimension of image by sexy clothing make that female mainly consist of in their twenties during May to October in 2003. The independent variables were: 1) The physical beauty dimension, 2) The negative estimate dimension, 3) The characteristic devaluation dimension,4) The elegance/ high grade dimension,5) The freshness/ beauty dimension,6) The sex appeal/ exposure dimension. Judging from each characteristic of costume in classified by articles, that is, colors, texture, shapes, details, and others-phenomenon of outerization of under clothing, print. We can know the clothes showing up our nice figures are the sleeveless design tied with strap, soft texture as silk chiffon and the colors that are not strong. And there were no embarrassed, ugly and pitiful clothing. Expressing sexy beauty by clothing is the result that the wearer produces intentionally by compounding design factors, it's the ideal when the observer's reaction and the wearer's intention correspond. Therefore, it will be helpful in expressing ideally if the subject, what kinds of sexy beauty the compounding design factors express, is studied carefully. Also it is expected to be used in grasping modem consumers' desires that want to look sexy, finding out how to express, dealing with the consumers' desires correctly, and the reference materials of the planning goods, sales promotion, and selecting of a medium of advertisement according to the consumers' desires.

In ancient times, architectural design was seen as a critical task in building technologies. Specifically, form, dimension and structural design are of significant. These aspects are associated with each other and to be emerged as a whole. Designing plan dimension was deemed to be the core of design technology due to its close relationship with module system. Thus, its evolution as well as development process typically represents and reflects the spirits and contents of design technologies in ancient China. In China, the materials regarding ancient architectural technology include Yingzaofashi(營造法式) of Song Dynasty and Gongchengzuofazeli(工程做法則例) of Qing Dynasty. They show many aspects concerning materials, structure, scale system and building. In Yingzaofashi, although the length of objects are decided by 'cai(材)' and 'fen(分)', there are no regulations on length, width and height of a building. However, in the construction of ancient buildings, the above mentioned basic scales are very important in both design and construction. The present paper attempts to discuss the significance, namely, the design principles of length, with and height of ancient chinese architecture.

Grading of aggregate influences significantly almost all of the concrete performances. The purpose of this paper is to propose practicable equations that express the optimized total aggregate gradation, by weight or by number of particles in a concrete mix. The principle is based on the fractal feature of the grading of combined aggregate in a solid skeleton of concrete. Therefore, equations are derived based on the so-called fractal dimension of the grain size distribution of aggregates. Obtained model was then applied in such a way a correlation between some properties of the dry concrete mix and the fractal dimension of the aggregate gradation has been built. This demonstrates that the parameter fractal dimension is an efficacious tool to establish a unified model to study the solid phase of concrete in order to design aggregate gradation to meet certain requirements or even to predict some characteristics of the dry concrete mixture.

Gate poly-silicon critical dimension is a prime characteristic of a metal-oxide-semiconductor field effect transistor. It is important to achieve the uniformity of gate poly-silicon critical dimension in order that a semiconductor device has acceptable electrical test characteristics as well as a semiconductor wafer fabrication process has a competitive net-die-per-wafer yield. However, on gate poly-silicon critical dimension, the complexity associated with a semiconductor wafer fabrication process entails hierarchical variance components according to run-to-run, wafer-to-wafer and even die-to-die production unit changes. Specifically, estimates of the hierarchical variance components are required not only for disclosing dominant sources of the variation but also for testing the wafer-level uniformity. In this paper, two experimental designs, a two-stage nested design and a randomized complete block design are considered in order to estimate the hierarchical variance components. Since gate poly-silicon critical dimensions are collected from fixed die positions within wafers, a factor representing die positions can be regarded as fixed in linear statistical models for the designs. In this context, the two-stage nested design also checks the wafer-level uniformity taking all sampled runs into account. In more detail, using variance estimates derived from randomized complete block designs, Duncan's multiple range test examines the wafer-level uniformity for each run. Consequently, a framework presented in this study could provide guidelines to practitioners on estimating the hierarchical variance components and testing the wafer-level uniformity in parallel for any characteristics concerned in semiconductor wafer fabrication processes. Statistical analysis is illustrated for an experimental dataset from a real pilot semiconductor wafer fabrication process.

Mostof existing CAD systems do not provide the advanced function for systematic checking of design and drafting errors in mechanical drawings. We have reported a computer aided drawing check system to single plane projection drawings made by a CAD system. This paper describes a checking method of dimensioning errors in mechanical drawings. The checking items are deficiency and redundancy of dimensions, input-errors in dimension figures and symbols, etc. Checking for deficiency and redundancy of global dimensions has been performed applying Graph Theory. This system has been applied to several examples and we have confirmed the feasibility of this checking method.
