Facing the challenges of urban form and space quality in a high-density environment, the paper puts forward the development trend of three-dimensional and multi-functional design for an urban high-rise complex, and analyzes the design methods of establishing an urban landmark, including multi-functional composition, three-dimensional space integration, three-dimensional traffic organization and energy flow programming. Meanwhile, combined with the specific design case of Yiwu World Trade Center, the practical experience of designing a high-rise complex in China's medium-sized cities is analyzed.

This research is focused on the 'Resident-participated Workshop' which targets the improvement of residential environment of apartment complex from the residents' point of view. The purpose of the workshop is to induce the residents interest and encourage them to participate in design process, thus, residents will be satisfied with the result with affection and achievement. This research aims the effectiveness of 'Resident-participated' design plan as a program which enables them to maintain and self manage in the long run. The object of this research was the public space within the apartment complex of Susojugong Rental Apartment Complex in Gangnam-ku, Seoul and followings are the contents; 1. Method of 'Resident-participated Workshop'. 2. Program of 'Resident-participated Workshop'. 3. Design analysis of improved apartment complex through 'Resident-participated Workshop' and selection. As a result, it was noticeable that 'Resident-participated Workshop' was an important factor in decision making of designs from the very first stage through communication. As a part of workshop program, design game used cubic models which was useful to enhance the understanding of the participants. It also induced the cubic conception so that intercommunication with the design specialists was possible. But, the development of various workshop method to increase the residents' interest and participation is necessary, especially, program development is required to change the residents' attitude towards the design plan. It is anticipated that a continuous related research is neccsary in this regard.

A quick-acting hydraulic fuse, which is mainly composed of a poppet, a seat, and a spring, must be designed to minimize the leaked oil volume during fuse operation on a line rupture. The optimal design parameters of a quick-acting hydraulic fuse were searched using the design of experiments method and the complex method. First, the $L_{50}(5^4)$ orthogonal array is used to find the robust minimum point among the 625 points of design variables. The search range can then be narrowed around the robust minimum point. Second, the $L_{25}(5^4)$ orthogonal array is used to obtain the variations of the design variables in the narrowed search range. The variations of design variables are used to set the structure of a polynomial equation representing the leakage oil volume of the quick-acting hydraulic fuse. The least squares method is then applied to obtain the coefficients of polynomial equation. Finally, the complex method is used to find the optimal design parameters where the objective function is described by the polynomial equation.

Accurate modeling of complex dynamic stiffness of the pneumatic springs is crucial for an efficient design of vibration isolation tables for precision instruments such as optical devices or nano-technology equipments. Besides pressurized air itself, diaphragm made of rubber materials, essentially employed for prevention of air leakage, plays a significant contribution to the total complex stiffness. Therefore, effects of the diaphragm should be taken care of precisely. The complex stiffness of an inflated diaphragm is difficult to predict or measure, since it is always working together with the pressurized air. In our earlier research, the complex stiffness of a diaphragm was indirectly estimated simply by subtracting stiffness of the pressurized air from measurement of the total complex stiffness for a single chamber pneumatic spring. In order to reflect dynamic stiffness of inflated diaphragm on the total stiffness at the initial design or design improvement stage, however, it is required to be able to predict beforehand. In this presentation, how to predict the complex stiffness of inflated rubber diaphragm by commercial FE codes(e.g. ABAQUS) will be discussed and the results will be compared with the indirectly measured values.

The main purpose of this study is to define the characteristics of emvironmental-friendly design which is found on in the planning of apartment housing complex. For this purpose, the subject of analysis were focused on the plans which had been authenticated an apartment housing complex development of Green Buildings. In conclusion, the characteristics of environmental-friendly design in the of apartment housing complex which are analysed through this study can be summarized as follows: It is shown that most plans hardly used the designs items such as 'preserving geographical feature' , 'use of substitutive sources' while the application ratio of 'making streamlets' , 'artificials afforestations' , 'making pedestrain road and bicycle road' is highest. this analysis means many planners and designers depends on only a few design elements when they plan apartment housing complex. it is because they don't have a correct understanding of environmental-friendly development.

An integrated structural design system can define and process complex design information that occurs in each of the design stages for flexible cooperation. It can also reduce human error on sequential design steps: preliminary design, analysis and detailed design. Therefore, it's very important to have consistent semantic expression and procedure for structural design information that has complex relationships. In this study, we introduce the object-oriented concepts and object-oriented database thechnique that provides high level semantic expression in order to develop an integrated structural design system.

This paper introduces a design of multi-dimensional complex emotional model for various complex emotional expression. It is a novel approach to design an emotional model by comparison with conventional emotional model which used a three-dimensional emotional space with some problems; the discontinuity of emotions, the simple emotional expression, and the necessity of re-designing the emotional model for each robot. To solve these problems, we have designed an emotional model. It uses a multi-dimensional emotional space for the continuity of emotion. A linear model design is used for reusability of the emotional model. It has the personality for various emotional results although it gets same inputs. To demonstrate the effectiveness of our model, we have tested with a human friendly robot.

Deciding peak-time demand will be most important factor to decide facilities' capacity of complex transfer centers. Concentration of demand is growing more and more in urban railroad that has 3 minutes headway by using MOE of 15 minutes demand. It is far from reality. Moreover there are various demand and reflection of business facilities' demand and commerce facilities' demand is being requested in complex transfer centers. This study focused on it and suggested demand calculation method about facility design of complex transfer centers.

Fractal geometry based upon the latest complex theory shows different features of design pattern quite different from the past. It is not yet sure which kind of effects it would bring about in the future, we think that it would help to create various spaces and organic design vision. Therefore we will look into the significances and adaptabilities in space design by studying fractal design principles of today's new model in space design
