A city development has been focused on solving a housing shortage of city resulted from rapid industrialization and population increase in city. However, such a development has caused many problems in environment, economy, safety, and so on. In recent, therefore, a new paradigm of a city development is required, and thus ubiquitous city (U-City) concept appears. U-City development, which combines construction method and IT technique, creates a new composite space, and help people improve quality of life in terms of solving many problems caused by existing method of a city development. However, there is no guide to build U-City up to date, and most present U-City projects have processed following past method of city development. Therefore, an objective of this paper is to suggest an explicit procedure of enforcement design in U-City system.

Front End Engineering Design (FEED), currently dominated by a few advanced countries, creates the highest added-value in the in plant construction industry. In the domestic plant engineering industry, it is difficult to acquire its own technology capability and experience due to lack of experience and shortage of experts in advanced design fields such as basic design and FEED. To achieve competitiveness with the advanced countries, it is necessary to establish smart training system for advanced plant design and FEED engineers. This study aims to design an integrated training framework for plant engineering and FEED using system engineering to build a smart plant engineering education system that learns design knowledge based on educational content and experience based on design stage for chemical plant.

To efficiently design safety-critical systems such as nuclear power plants, with the requirement of high reliability, methodologies allowing for rigorous interactions between the synthesis and analysis processes have been proposed. This paper attempts to develop a reliability-centered design framework through an interactive process between Axiomatic Design (AD) and Fault Tree Analysis (FTA). Integrating AD and FTA into a single framework appears to be a viable solution, as they compliment each other with their unique advantages. AD provides a systematic synthesis tool while FTA is commonly used as a safety analysis tool. These methodologies build a design process that is less subjective, and they enable designers to develop insights that lead to solutions with improved reliability. Due to the nature of the two methodologies, the information involved in each process is complementary: a success tree versus a fault tree. Thus, at each step a system using AD is synthesized, and its reliability is then quantified using the FT derived from the AD synthesis process. The converted FT provides an opportunity to examine the completeness of the outcome from the synthesis process. This study presents an example of the design of a Containment Heat Removal System (CHRS). A case study illustrates the process of designing the CHRS with an interactive design framework focusing on the conversion of the AD process to FTA.

To solve structural optimization problems, it is necessary to integrate a structural analysis package and an optimization package. There have been many packages that can be employed to analyze reinforced concrete plane frames. However, because most structural analysis packages suffer from closeness of systems, it is very difficult to integrate them with optimization packages. To overcome the difficulty, we proposed a possible alternative, DAMDO, which integrates Design, Analysis, Modeling, Definition, and Optimization phases into an integration environment as follows. (1) Design: first generate many possible structural design alternatives. Each design alternative consists of many design variables X. (2) Analysis: employ the structural analysis software to analyze all structural design alternatives to obtain their internal forces and displacements. They are the response variables Y. (3) Modeling: employ artificial neural networks to build the models Y=f(X) to obtain the relationship functions between the design variables X and the response variables Y. (4) Definition: employ the design variables X and the response variables Y to define the objective function and constraint functions. (5) Optimization: employ the optimization software to solve the optimization problem consisting of the objective function and the constraint functions to produce the optimum design variables. The RC frame optimization problem was examined to evaluate the DAMDO approach, and the empirical results showed that it can be solved by the approach.

This study analyzed the learning effect, through a satisfaction survey and NVivo qualitative analysis, of fashion design classes using humanities self-reflection writing. The results are as follows. First, with regard to learning satisfaction, learners perceived the class as efficient and showed overall satisfaction. Second, learners' opinions were classified into self-reflection writing, design process, new experience of expression, and the understanding of class activities. Third, in self-reflection writing, learners discovered their tendencies and values while exploring their identity through deep thinking. Fourth, in the design process, learners set the design concept consistently through writing. Fifth, in the new experience of expression, learners recognized the idea produced through writing as the result of thought and considered it a new expression method for design. Sixth, in the understanding of class activities, learners were interested in the process and considered it an activity through which to build their own style in design expression. Design class activities using self-reflection writing drew a positive response and presented the possibility of educational use. The teaching method of this study is expected to be used as a humanistic method for expressions in various design fields.

The color is one of the important key words in Fashion arena today. In fashion, the image and concept changes by use of color or color combinations. The purpose of this research is to pursue the characteristics of color and color combinations through analyzing the colors utilized in oriental fashion design. It is necessary to define the oriental fashion design to build a criteria for collecting law materials for analysis of the research. As a conclusion, traditional oriental colors already used in various traditional artifacts were popular in use by many fashion designers with volatile attitudes towards its original symbolic meanings or philosophy. For example, yellow and red stands for gorgeous or sexy images through fashion design instead of express its original symbols of power and prosperity. The Complimentary Color Combination in hue, value and intensity of colors were also found in fashion design impling oriental images. While Contemporary Fashion Trend Color were also used in expressing Oriental images with oriental details considering fashion market. In using Oriental colors The characteristics of oriental colors and its combinations used in fashion designs are significant and their influences are meaningful not only in fashion design but also adjacent design areas.
