These days information technology and internet have made startling progress. In these developing environments, the strategy or marketing based on existing off-line is getting more difficult to accomplish the role of the improvement of business competitive power, and they are bringing out a lot of changes in information management and marketing performance method about consumers due to digital networking between companies and consumers. These developments and changes make many varieties in the way of design studying methodology. Therefore, in this study, considering the aspects of design, society and environment, after I developed the consumer response framework about products design which is argued by Bloch(1995) ; distinct relationship model among preference degree- design image adjective - design factors, we established design information abstraction solution combined with the interaction based on IT as eCRM in real time. This suggested solutions will provide product designers with good information in finding the design factors which consumers prefer.

The purpose of this study is to develop ICT utilization learning materials for a chapter titled 'Environment Friendly Clothing and Reform of Clothing' in technology and home economics textbooks for Year 2 students in middle school. The research methods were selected from ten types of junior high school technology textbooks, which were revised in 2009, and mainly focused on items such as jeans, shirts, shirts, cardigans, and skirts, Using selected textiles and basic design t-shirts, five works were made using structural and decorative details. The results of this study are as follows. First, textile products shown in the chapter 'Environment Friendly Clothing and Reform of Clothing' are most commonly worn and found in daily life. With regard to a reuse method, structural changes to clothing are proposed. For example, cases relating to the changing of a neckline or the use of a shirt or a sleeve are presented. There are some decoration methods adapted in reuse; using ornaments, such as spangles and emblems, patchwork, shirring and the constucting of collages. Second, following the plan, 5 items are designed with T-shirts, shirts, cardigans and skirts. For the T-shirt design, other fabrics including organza and neoplan are used from design point of view, in addition to reused textile products. Detailed structural changes of necklines, sleeves and collars and detailed and the ornamentation method including shirring, smoking, patchwork and collages are used. Third, this study proposes 6 categories (profile, design planning, diagram, reused textile product, production method and order and pictures of T-shirts developed) under the title of 'T-shirt Made Out of Disposed Clothing', selecting a blog as active teaching and learning material as a part of the ICT utilization in educational settings.

The façade, a fundamental function as a skin that protects human life from external environment such as cold and hot weather, snow, rain, and wind, etc, has served as a media for communication between indoor space of the building and outside space. From the media for communication point of view, the approach to envelope design, in which environmental elements are transmitted internally through the filtering of external environments, has been evolving in various ways from the past to the present. Today, modern architecture technologies including curtain wall systems and user-friendly computer programming and environmental analysis programs demonstrate a differentiated approach to envelope design related to the indoor environment. For this reason, it is worth noting that the envelope design factors and trends that appear variously in the UNStudio's projects before and after the 2000s. The factors reflected in the envelop design in conjunction with the indoor environment obtained through the case study of the UNStudio's office projects were daylight environment, thermal environment, ventilation, noise, privacy and view, and consideration for daylight environment and thermal environment was reflected in many cases through the case study. Looking at the changes in the diagrams in order of year, it can be seen that the envelope design using the environmental analysis tool has been performed since 2006. This is a clue to show the envelop design changes from the conceptual method to the data-based one. The diagrams and analysis results related to the envelop design showed that the thermal environment related to solar radiation was the most, and no diagrams and analysis related to the indoor illumination were found. Since 2010, PV panel installation has been shown in the envelope design, which can be found in the increased efficiency of PV panels due to the technological advances and the decrease in production cost.

Tight integration between design and analysis processes and the data representation in the ship design application domain have been studied in this paper. Multi-Representation Architecture for design and analysis integration, proposed at Georgia Institute of Technology, has been carefully investigated for the application in the initial ship design stage. The MRA approach facilitates efficient generation of analysis models from the initial ship design data, thus reducing design lead time. Easy generation of analysis model is important because it allows quick analysis iteration under frequent design changes. The SMM, ABB and PBAM are defined for the analysis model of the typical ship structure. Only a part of the typical initial ship design data has been considered in the experimental implementation of the proposed approach. However, the prototype implementation shows that the application of MRA approach in the structural ship design domain is quite feasible. It is also contemplated that the same approach can be extended for other design and analysis views in the ship design domain.

Nuclear Power Plant consists of about 1.4 million facilities. and the design standards and design requirements for the continuos utilization and safety of facilities are complexly connected with the facilities. When a design change for facilities or design requirements is occurred at the time of construction or operation, there are a lot of facilities, design requirements, and design bases that are affected by the facilities or design bases being changed. The above design changes are so complex that the existing document-bases design change process is time-consuming and may also cause human error. In this study, we developed a design requirement taxonomy that can be applied to the data-centric design bases document that can improve it. To do this, we analyze the design elements from the highest level to the lowest level applied to the nuclear power plant, and classify the design elements according to the characteristics of the design elements.

In this paper, observer-based H$\sub$$\infty$/ controller design method for singular systems with time-varying delay by Just one LMI condition is presented. The sufficient condition for the existence of controller and the controller design method are presented by one perfect LMI approach. The design procedure involves solving an LMI. Since the obtained condition can be expressed as an LMI form, all variables including feedback gain and observer gain can be calculated simultaneously by Schur complement and changes of variables.

Robust parameter design is to identify appropriate settings of control factors that make the system's performance robust to changes in the noise factors that represent the source of variation. In this paper, we introduce a factor analysis approach to simultaneously optimize multiple quality characteristics in the robust parameter design. An example is illustrated to compare it with already proposed method.

The purpose of this research is to examine the expression methods of Haute Couture designers' high value-added jacket designs, In order to achieve this, the positions and sizes of the design component items of tailored jackets designed by Haute Couture designers from the 1940s to the 1970s were analyzed. The results of the analysis are as follows. First, the silhouette changed while leading the contemporaneous fashions, and such changes could be confirmed by the width and length of the jacket's shoulder, chest, waist, and hem that determine the silhouette. Particularly, the length of the chest changed which signifies that the depth of the armhole was playing an important role in the production of high value-added jackets in relation to the sleeves and the fit of jackets. Second, the position and the size of the dart are the components that can express the fit of a jacket and the designer's creativity, The starting point position of the dart and the position passing by waist, and the position of the end of the dart were placed in the position beyond B.P. depending on the designer's creativity and techniques, deriving the changes of the silhouette and creating high value-added jackets. Third, the tailored collar, which was a three-dimensional component made up of the upper collar, gorge line, lapel, and break line, was an important component that could express high value-added jackets. Changes in the width and the height of the break line position of the sides of the neck were represented as changes in the neck size of the collar, and changes in the vertex locations of the upper collar corner-point, the gorge line (the corner-point of the lapel and V zone) were also represented as diverse tailored collar designs. And the differences in the width and the length of each component of the collar were related to each other and represented as changes in the slope and angle of the collar outline. Fourth, the changes in sleeve designs of the jacket were in such items as the width of the sleeve opening, the width of the sleeve hem, and the length of the sleeve, and were represented as diverse sleeve designs such as widened sleeve opening types, and straight line types.

During the construction project period, a lot of change orders happen in the design and construction stage Especially, The change order during construction stage causes the huge construction cost increase and duration delay. Accordingly, research on the change order of the construction stage is being progressed relatively active in the design stage, but the design changes are rarely made. In the design stage, the owner has to pay a design addition cost when change order due to the demands of owner happens. However Korea has not the specific standard about design additional cost in design stage. Therefore, this study analyzes problems of design additional cost estimation methods through the case study, and then indicates the method that the ratio distributes to details dividing design tasks and the method of the PM(Project Management). Eventually, this study expects to minimize claim related the design additional cost in design stage.
