Nowadays Industrial Design appears to us as provided products in the market through only User Interface and Technical Improvement. Consumer purchasing products intend to grant the meaning for the product by mobilizing his specific feeling and experience the moment he contact products the first time. As metaphorical character shown in the product is named to the Product Language, Industrial designer shall constantly proceed the study on the exact understanding or processing method. As Objects or products using by us imply aesthetical value, it appears to be different according to the diverse condition of products be different according to the diverse condition of products to be used. In case objectivity is unsatisfactory, aesthetic character shown in the product requires new instrumental system. Product analysis applied aesthetical measure of BIRKHOFF can be applied as tool for inherent metaphorical character of product and product development. With this, Design operation shall be much easier. So Application of aesthetical measure is not only a system but a tool giving help to carry out more smooth design process.

In this paper, we introduce a new architecture of PSO-based Polynomial Neural Networks (PNN) and discuss its comprehensive design methodology. The conventional PNN is based on a extended Group Method of Data Handling (GMDH) method, and utilized the polynomial order (viz. linear, quadratic, and modified quadratic) as well as the number of node inputs fixed (selected in advance by designer) at Polynomial Neurons located in each layer through a growth process of the network. Moreover it does not guarantee that the conventional PNN generated through learning results in the optimal network architecture. The PSO-based PNN results in a structurally optimized structure and comes with a higher level of flexibility that the one encountered in the conventional PNN. The PSO-based design procedure being applied at each layer of PNN leads to the selection of preferred PNs with specific local characteristics (such as the number of input variables, input variables, and the order of the polynomial) available within the PNN. In the sequel, two general optimization mechanisms of the PSO-based PNN are explored: the structural optimization is realized via PSO whereas in case of the parametric optimization we proceed with a standard least square method-based learning. To evaluate the performance of the PSO-based PNN, the model is experimented with using Gas furnace process data, and pH neutralization process data. For the characteristic analysis of the given entire data with non-linearity and the construction of efficient model, the given entire system data is partitioned into two type such as Division I(Training dataset and Testing dataset) and Division II(Training dataset, Validation dataset, and Testing dataset). A comparative analysis shows that the proposed PSO-based PNN is model with higher accuracy as well as more superb predictive capability than other intelligent models presented previously.

The garden has long served as away of thinking about nature and about culture and how each influences the other (Francis and Hester, 1990). This study, viewing the garden as a representation of the ideal, tried to seek for detailed aspects of the aforementioned ideal with the representative examples of Thomas Jefferson's gardens. Hidden behind his best known position as a politician was his other career: designer and creator of several gardens. Monticello, Academical Village, and Poplar Forest represented not only his ideals of national values like freedom, democracy and agrarian society, but also a yearning for the rural area and ideals for higher education realization. His personal desire and ideal are represented inside the spatial order, together with his ideals as a politician and the pioneer of new country. By representing the symbolic meaning metaphorically and restructuring it through a spatial scheme, Jefferson's ideal was admired and shared with visitors. In this way, Jefferson's gardens were practical stages to reveal his ideals.

In this paper, we analyze workflow management system in programming language aspects. Many workflow characteristics such as workflow relevant data, workflow control structures, and workflow application invocations are studied and compared with those of distributed parallel programs. Although there exist minor differences between them, we found that there exist surprisingly many analogies between them. Based on this observation, we suggest to view workflow management system as distributed parallel program development platform. This new view on workflow management system provides users consistent view on workflow and workflow management system and with this view workflow management system designer can cope with arbitrary requests from the users keeping design consistency. Moreover the analogy between workflow and program provides a basis to apply program analysis techniques to the analysis of workflow.

In Accordance with the change of design paradigm, the design process has changed into user-centered workflow from designer-centered workflow. Since the purpose of the past research methods is quantitative analysis or the understanding of the present situation, it doesn't fit in practical design that expressed the user's needs. Therefore, the real data about what they see and how they feel will be useful for the user-centered design. This paper's objective is to analyze eye-movement recordings and pupil size of user for mobile interface design. For this objective, it was experimented on that the user's eyegaze data of using a mobile phone by the Eyegaze Interface System, and analyzed three levels of user's task performance. The results provided evaluation of new developed and old existing interface design of mobile phone by the experiment of eye-movement recordings and pupil size. The benefit of results is compliment of the limitation of current usability test through visual characteristics of design and qualitative data of user.

Frank Lloyd Wright, a master of the 20th Century Ar-chitecture, contributed tremendously in creating a wholly new form of American architecture called Prairie Style. His idea behind the development of the building structur-al system, organic relationships between inner and outer space, horizontal vertical lines, and idea of extending and expanding interior spaces came from nature. He had completed over 390 projects throughout his life and 90% of those projects were residential design. The most typical characteristic shared by many of his residential design was that each design element, whether it is functional or aesthetical, has close relationship to or-ganic nature, human scale, theoretical floor plants, and maximum emphasis on horizontal lines in respect to na-ture. His concept of "flow of spaces" reformed common the-ory of room next to room in a enclosed space. His sense of "wall" was no longer the side of a box. Careful selec-tion of finishing materials, colors, and natural images en-hance the design as well. F.L. Wright was an artist, designer, and architect who believed the exterior space should have direct relationship to the interior space. His architectural philosophy was not only to design exterior of architecture but also to ful-fill his space through the careful development of interior elements such as furniture, and lighting fixture. Even the patterns for leaded glass windows were designed to have unified appearance from outside to inside of the house. The objective of this study was to analyze floor plans, spatial organizations, and interior design elements of the houses which represent the best of F.L. Wright's design principles and philosophy behind Prairie Style. The meth-od used to collect informations for this study was based on books, articles, journals, and actual site visits. actual site visits.

At present, the design of extrusion dies and operation in extrusion companies are primarily based on trial and error. The experience of the die designer, the press operator and the die corrector determine the performance of the extrusion die and the efficiency of the process. In order to produce defect-free products of desirable quality in terms of strength, surface quality and geometrical dimensions, it is important to obtain more knowledge of the processes that occur during extrusion. Recently, to reduce the costs of designing and manufacturing of extrusion dies, and to ensure the quality of the extruded products, numerical simulation for extrusion processes such as FEM (finite element method) is applied increasingly and becomes a very important tool for the design and development of new products. However, most of the studies about FE simulation have been accomplished for simple geometry and low extrusion ratio in the filed of steady metal flow conditions. The extruded products of AI alloy in industrial practice involve complicated sectional geometry. This study was designed to reduce the time of die design and manufacturing in the extrusion process using FEM simulation. FEM simulations of extrusion process were performed in non-steady states conditions by changing weld plate included in extrusion die set. Product which was employed in this study is heat sink that has been used in the parts of heat exchanger of electric circuits. It is generally applied for aluminum or its alloys due to heat efficiency and easy production of complicated shapes, and manufactured by extrusion process. The simulated results showed that weld plate shape in extrusion dies influences meta] flow and dimensional accuracy of products.

In this paper, we present a new framework and synchronization mechanism to effectively support developing real-time communication service by using a real-time object model named TMO (Time-Triggered Message-Triggered Object). Also, we describes the application environment as the DHS(distributed high-precision simulation) to guarantee real-time service message with TMO structure in distributed network systems. The TMO scheme is aimed for enabling a great reduction of the designer's effort in guaranteeing timely real-time communication service capabilities of among distributed multi-nodes systems. Our real-time framework provide the consistent construction and configuration of tine-triggered processing components across heterogeneous distributed object environment more easily. It has been formulated from the beginning with the objective of enabling design-time guaranteeing of timely action. In the real time simulation techniques based on TMO object modeling, we have observed several advantages to the TMO structuring scheme. TMO object modeling has a strong traceability between requirement specification and design.

This research is intended to study literatures relating to western rocking chairs style in early 20th century in order to provide basic data of designs for rockers of today in Korea and investigate characteristics of rocking chair from academic, formative and pragmatic perspectives. During the first half of 20th century, western rocking chairs (1925~1945) embodied actively the simple functionalism concept that furniture design must follow functionality considerations. Therefore, bare wood rocking chairs were without any surface decoration and tubular steel frame rocking chairs often included black leather upholstery in a bold attempt to express exposed structure. And the fact that tubular steel produced such lightweight furniture was crucial importance. Many Modernist designer created curvaceous lines of new pattern changes in their furniture. The structure of Modern rocking chair became all-important, for stylistic as well as functional reasons. Designers equated exposed structure of tubular steel and wooden frame with integrity and rationality and create an equalitarian style of design. Especially, designers in the early 20th century did use various brilliantly colored upholstery and wooden frame with simple forms of modern characteristics.
