The ACI 318 stress block parameters have been closely examined for validity of their values in evaluation of flexural strength and deformability. For this the conventional definition of stress block has been used. The comparison of parameter values between ACI stress blocks and the exact approach implies that an alternative idealization other than the rectangular stress block may be required.

A design process is difficult to describe comprehensively because a design problem has a multi-disciplinary nature and the design itself evolves as solutions are attempted by the designer. The process of design has been investigated in this paper with the purpose of characterizing the role that a system of this kind may have. In defining the system, an approach has been used that privileges the relationships with the existing CAD tools based on data exchange standards in course of definition today. Integrated design environment normally consists of a centralized data model a data management system and a set of CAD tools. In this study, all further investigations are directed towards the data management system, as one of the main components of the proposed environment. Moreover, product modeling, as a prerequisite for the data management core, is taken into special consideration.

Environmental designers face a wide range of problems to be solved in their day-to-day works. The scale and number of problems and so enormous that designers should be a way out to meet these complex situation. Lately, environmental design process based on systems a.pproach is chosen for design methodology. It is a very complicated procedure with many alternatives. It is a evolutionary process that establishes the solution of a series of problems. This study attempt to tell the designer how to find design solution to problems and how to organize form as solution problems. The model of this design process is largely composed of three phases; Phase I : Problem definition and existing system analysis. Phase II : design goals and objectives, design criteria Phase III : creative process of design form.

Contemporary architecture has two different movements that one is the utilization of digital technology and the other is the inclination to nature. After deconstructivism in architecture, the tendency of design shows the fusion between digitalism and organicism and as a consequence the phenomena of 'skin expression' has emerged which can be thought as 'organic digitalism' or 'digital organicism'. The definition of skin tendency in environmental design is the design of nature based on the technology. As a result, the surface becomes the design issue compared to structure and the momentum for new aesthetic value. There are post-structuralism, complex system theory and the organic architecture as theoretical background for the tendency of skin expression. Specially the ideas of post-structural philosophy has effected deeply to the formation of its movement and also offered the theoretical nutrition for digital architecture. The characteristics of the skin tendency can be analyzed as topological transformation, smooth continuum, deterritorialization, ecological response system, and tactility. These design characteristics has combined with conventional material and design vocabulary to transform and develope new spatial conception.

This study aims to inquire into the expressive characters of Shiro Kuramata's works regarding his design languages. His design languages, based on sentimentality and aesthetics characteristic of the orient and his unique memories and experiences, can be defined as nongravitation, fioatation and transparency. And the definition can be completed by his unique extinguishing technique, eliminating the structure with materials without feature, such as glass and acrylic and expanded metal, steel mash and 'Star piece Terrazzo' a material which he has invented. This study examines Shiro Kuramata's design works from the late 1960's to 1991, the year of his death, the background of his growth and the art and people who have influenced him. It also looks into the indigenous cultural background and his unique memories and experiences. The study also considers his furniture works and interior design to read his languages properties of the materials and expressive techniques. The study presents data on Shiro Kuramata and puts forwards the significance of his works and tries to lead the way of the interior design by application techniques of materials.

The Furniture Industry is, which is taking Charge of the large Portion of environmental Pollution as a nun Consumer of Resources, therefore, in a Furniture Design, active Argument of the Researches and the related Constituents to the Design and Material is very absolutely required recently The Furniture Design which Ecology was applied to can minimize the environmental Burden through the Resources and Energy Consumption Reduction and cyclic Utilization within the Earth Ecosystem, and proceed to the Presentation of the Possibility to solve the recent environmental Problems. This Study was written as part of the first Step in the Development of independent Eco-Label System and environmental Criteria for Furniture and national Furniture Industries. It contains the Definition of Furniture, ecological Design and ecological Furniture (Chapter2). and Chapter 3 Presents Characteristics of ecolo91cal Furniture. Chapter 4 Provides a Summary of the specific Criteria on a Materials used for Furniture Design with the relevant environmental Issues in the Life Cycle of Furniture, and also health 8t safety related Issues and performance Issues.

The purpose of this these is to study on the environmental design brand for the vitality of corporate image. To achieve the purpose of this study, the methods and contents are as follows: 1. Conforming the concept of the corporate environmental design brand. For that explaining the definition and the tradition of brand and the meaning of corporate identity and corporate environmental design system. 2. Explaining the factors of the corporate environmental design. For that 1) explaining the expression of the corporate identity 2) Explaining the expressive factors of the corporate identity. For that, studying the style and the theme. 3. Studying the cases of the corporate environmental design brand. By these methods and contents, we will study environmental design brand for the vitality of corporate image.

Since most engineering problems have had open-ended and ill-defined characteristics, design process is in advance attended with determination of alternatives based on realistic constraints after definition of appropriate problem. And it is completed with selection of best alternative through their comparison and investigation, and with performance of selected-alternative's detail design. As the process of structural design compared with that of general design, this paper presents a paradigm which can generate structural design alternatives, select optimum structure among them and simultaneously set its optimum design variables in reference of several objective as a result in more extended design region. For this purpose, specialized genetic algorithms which can handle design alternatives and multicriteria problems is used.

본 논문은 C++에 분산 객체 프로그래밍 기능을 추가한 D++ 언어를 제안한다. 대등관계 복제객체 모델을 지원하는 D++는 분산 클래스의 정의, 멤버 함수의 일치성 제어 정의 기능, 그리고 영구 객체 이름에 기반한 분산 객체를 정의할 수 있는 언어 구조를 제공한다. D++ 프로그램에서 새로이 생성되는 분산 객체는 생성 시에 제공되는 객체의 영구 이름과 동일한 영구 이름을 갖는 분산 객체가 존재할 경우 해당 객체들과 복제 관계를 유지함으로써 정보를 공유한다. 각 복제 객체들은 서로 간에 대등한 관계를 가지며, 멤버 함수 정의 시에 기술되는 특성에 따라 일치성이 유지된다. 이 같은 D++의 분산 객체 모델은 실시간 그룹웨어의 기본 요구 사항인 분산 환경에서의 정보 공유 및 사건 공지 기능을 자연스럽게 해결해 주기 때문에 실시간 그룹웨어의 개발을 효율적으로 지원할 수 있을 것으로 기대한다. Abstract This paper proposes D++ programming language that is an extension of C++ for distributed object oriented programming. The D++, which supports peer-to-peer object model, provides new language constructs for the definition of distributed classes, the definition of the consistency control of the member function and the definition of distributed object variables with the persistent name. In D++, when the persistent name of a newly created distributed object is same as that of an existing distributed object, the new distributed object replicates object state of the existing distributed object and thus they share the object state. The replicas have peer relation and the consistency among them is maintained according to the characteristic described on the definition of designated member functions. It is expected that D++ language increases efficiency in development of real-time groupware because the distributed object model of D++ naturally supports the information sharing and event notification that are the basic functions required when building real-time groupware.
