Concepts, methods and tools for interactive CAD-based concurrent engineering design optimization of mechanical/structural systems and components which are critical in terms of cost development time, functionality and quality, are presented. The emphasis is on implementation of methods and capabilities for the optimization of composite structural system, and the integration of design process and manufacturing process of composite structures into standard CAD-based concurrent engineering environment The optimization of composite fuselage structures are performed under concurrent engineering environment for the example.

This study starts at the at-risk children(the students in the margins)' needs for the inclusive education environment who increased lately. It is studied in the limited scope, which is about spacially 'playground' and 'Sensory integrative therapy' in terms of the special education therapy. The 6 environmental setting principles are suggested, which is redefined in terms of suitable for applying to the environment design based on the training way and arbitration principle of J. Ayres' Sensory integrative therapy. And then various environment design methods are drawn from above-mentioned 6 principles, they are categorized in 4 elements for environmental setting - sensory element, behavior element, mental element and design expression element. This trial brings daily practice of therapeutic stimulate to sensory integration dysfunction children, and sensory experiential diversity promoting development to general children. Expecially it has some advantage that at-risk children(the students in the margins) feel a sense of belonging as a member of society.

Environment problem has proposed in the world at large, the desire for environment conservation and one's value change which lay emphasis on lasting human sensibility are increasing. Constant human mind and ecology centered in space is presenting as future space design substitute plan which is based on fundamental material quality in the space such as environment and human ,naturalist or Green Design, pro-environment construction, sense design and etc. So, we intend to anthropocentric value and get out of satisfaction of function as the past physical environment equipment which is applied the elements of ecology based on the organized body and interaction with human. A form of sensitive space is divided into sentient space, expressing method and material, change of space according to the flow of time, and is expressed in a more segmented form of sensuality by being replaced into a new sensitive space through transaction with human, who occupy within the space. The space embodiment which is satisfied human sense regards as alternative plan intention for the future, through two subjects relativity between the elements of ecology and sense, we will find the influence of sense as each space trait of the elements of ecology, examine sense form in the space with the synthetic summary. It is significant presentation for the lasting space based on anthropocentric delightfulness as the design which moves human mind while designing the space for this pattern of sense space.

Until now, the stealth design to reduce the infrared signature of ship haven't been carried out using the proper design criteria. The study on the maritime meteorological environment in the Korean seas hasn't been accomplished yet, so the design criteria of the maritime meteorological environment was just given by the engineering sense without experience of the Navy and/or of the shipyard. Even in rather good conditions(summer condition), the estimated IR signature of a ship showed larger values and couldn't predict the worst condition during the operation of a ship at sea. In this study, domestic maritime meteorological data were collected and variables affecting the IR signature of a ship had been derived through the sensitivity study of IR signature according to the maritime meteorological environment in Korean seas. The basic study on the criteria of the stealth design of IR signature has been carried out.

The engineering process including design, analysis/evaluation and manufacturing activities is becoming one of the key issues to embody a concurrent engineering concept. This paper proposes a framework to integrated the complicated engineering design and manufacturing processes under the concurrent engineering environment. The framework offers the following facilities: (1) to represent the complicated engineering process (2) to coordinate design activities and execute the process in a distributed environment (3) to support a communication among the related engineers. The engineering processes is depicted using process flow graphs that consist in tasks and the corresponding input and output data. The engineering activities in the defined processes can be executed in a distributed environment through process controller of the framework. Engineers can communicate to suggest their opinions and to exchange product information in the framework. We have conformed the CORBA standard to integrate various distributed engineering the and communicate among them, and used a Java to support the platform independent environment on the Internet. Since the proposed framework an be a formal approach to integrate the engineering processes by providing formalism, parallelism, reusability, and flexibility, it can be effectively applied to embody the concurrent engineering concept in a distributed environment.

The purpose of this study, which has been conducted as a government and academic joint project, is to introduce the design, production and installation of the structures exhibited to let people know the meaning the environment-friendly eco-park - Haneul Park that is located in Mapo-gu, Seoul. The exhibition was held as a part of Green Garden Panorama of Seoul Design Fair 2010 and used the stands of Jamsil Sports Complex as the exhibition space. The key contents of the exhibition consist of four elements; firstly, green plants were placed on the first and second floor stands of the complex in order to create the space inside the main stadium as a space that symbolized green environment. Secondly, the usability of the containers of food was maximized to attract the spectator's interest and induce desire to have it. Thirdly, the efforts of the Mapo-gu office for green environment were emphasized using environment-friendly materials. The process and meaning of the transformation of Nanji Island that had been a waste dump site in the past into Haneul Park - an environment-friendly eco-park were expressed by a four-stage space structure. The majority of installations placed in each stage were sold to visitors during the event so as to minimize the generation of wastes after the event.

The concurrent engineering technologies have been broadly used in the field of the design, testing, manufacturing and maintenance works to reduce development time and costs. For this purpose, many design environments with the product data management system, the virtual engineering system and web database system are developed. In this research, we developed the driving simulator of the KTX(Korea Train Express) as a basic study for building the concurrent engineering design environment of rolling stock. The virtual track was developed from the Seoul to the Busan and the Daejeon to Mockpo to generate immersible driving environment. Also, fault generation systems were developed to educate drivers of the KTX. We expect to reduce the time and costs of newly developed rolling stock using the design environment developed in the research.

Modernity which is superficial phenomenon set off the mass scale for mass consumption and provide uniformly artificial environment. But natural destruction, environment pollution, resources exhaustion and so on has been caused by this and now ecology is threatened by destruction and damage beyond the limitation and human beings survival is even threatened. Accordingly furniture development for environment preservation considered environment problem is the urgent real situation. Recent paradigm is the concept of Eco-design which is the green design possible to live together in symbiosis, and new types of alternative furniture are needed in Korea as well. 'Furniture for disassembly' is presented as new method for alternative furniture.
