Design changes frequently occur while design activities are performed. If the impact of design changes is estimated, design efficiency can be improved. But, the types of design changes are various and they can affect other design parts. Hence, it is difficult to deal with design changes directly. The purpose of this research is to develop systematic algorithms for change propagation tracing and change impact analysis, and then to implement a change impact analysis system. We have selected a process-based design and a design environment which is composed of design parameters and constraints. The algorithm for change propagation tracing tracks the change propagation of design parameters and finds design parameters, constraints and tasks which are probably changed. In the algorithm for change impact analysis, a change impact value is calculated from the list of changeable tasks. These two algorithms have been implemented into change impact analysis system (CIAS). CIAS has been applied to the redesign of 2 stage gear drives. CIAS can improve the efficiency of design activities. If there are many alternatives for a design change at the redesign step, designers can calculate the change impact value of each alternative and perform design change activities in the direction of minimizing design change impact.

In Korea, global warming caused by the climate changes impacted on weather system with increase in frequency and intensity of precipitation, and the rainfall pattern changes significantly by regional groups. Furthermore, it is expected that the regional and annual fluctuation ranges of the rainfall in the future would be more severe. Nowadays, agricultural drainage system designed by the existing standard of 20-year return period and 2 days of fixation time cannot deal with the increment rainfall such as localized heavy rain and local torrential rainfalls. Therefore, it is required to reinforce the standard of the drainage system in order to reduce the agricultural flood damage brought by unusual weather. In addition, it is needed to improve the standard of agricultural drainage design in order to cultivate farm products in paddy fields as facility vegetable cultivation and up-land field crop have been damaged by the moisture injury and flooding. In order to prepare for the changes of rainfall pattern due to climate changes and improve the agricultural drainage design standards by the increase of cultivating farm products, the purpose of this study is to examine the impact of climate changes, the changes of relative design standard, and the analytic situation of agricultural flood damages, to consider the drainage design standard revision, and finally to prepare for enhanced agricultural drainage design standards.

Sustainability in fashion cannot ignore fashion attributes required for the design of rapidly changing and innovative products. This study examines "Re-Birth Design" development and provides a means to apply academic and industry perspectives to the investigation of Re-Birth fashion product development. This study defines "Re-Birth Design" as stock that has been designed and launched through distribution channels, subsequently returned unused, then improved and reborn into a new product for redistribution. This study analyzed specific cases. We selected 100 designs for Re-Birth from 11 brands of "K" fashion company in Korea, to be successfully sold in 2014. These cases are used in the analysis and are categorized into design types. As a result of the analysis, "Re-Birth Design" had five levels: Level 1. Changes in supplementary materials such as adding or removing decoration, Level 2. Changes in patterns or materials (changes within the product), Level 3. Partial changes in design (leading to a new design), Level 4. Complete deconstruction and rebirth of the design, and Level 5. Complete deconstruction followed by the use of the design source for a new product that is not a garment. This study analyzed products owned by brands, as well as successful cases of Re-Birth designs that reused existing resources, reduced energy consumption, and increased environmental and economic efficiency by recreating new products that could be resold.

This paper focuses on the spatial changes that create a three-dimensional or deep feeling on the surface of a scarf centering on the cube shape. Through this, consumers with various tastes were able to satisfy their image presentation. The cube form has simplicity and order and is likely to be used as a formative object. The cube shapes can be expressed in various forms through visual and perceptual spatial changes by presenting various shape changes based on the viewpoint of the two-dimensional silk surface, that is, by changing the eyes' position and orientation. Various visual theorists' discussions about cube-shaped visual changes were discussed. In addition, the three-dimensional spatial illusion caused by the shape and color of Victor Bazaarelli's cube was examined. The cube shape was printed silk surfaces to give a three-dimensional sense of space on a two-dimensional scarf design using the size change, the difference in the length of the line, and the color change. As such, the cube shape has infinite possibilities as a method that can express three-dimensional depth and space on the flat surface of a scarf. Therefore, it is hoped that this study will be applied to various aspects as the basic data for the scarf design that expresses the spatial changes in the form of cubes.

인간의 모든 주제는 목표와 절차와 수단을 갖고 있다. 이러한 점에서 사회에서의 하위체계는 이데올로기, 제도와 규범 그리고 기술과 경제로 구분하며 문화에서는 가치적 문화, 규범적 문화 그리고 용구적 문화로 구분된다. 기술과 경제, 그리고 용구 문화에 직접 연관되어 있는 디자인의 경우, 앞의 세 가지 사항과 관련하여 상징적 가치, 미적 형식 그리고 기능성의 측면을 지니게 된다. 산업 사회의 틀을 벗어나고 있는 지금, 사회는 엄청난 변화의 와중에 있으며 디자인 또한 과거의 물질적 개념을 벗어나 새로운 영역으로 확대되어 가고 있는 상황이다. 그러나 이러한 변화는 디자인 자체의 변화라기보다는 디자인의 상위 개념 즉 문화와 사회가 변화하기 때문에 비롯되는 것이라고 볼 수 있다. 이런 점에 주목하여 본 논문에서는 사회 변화와 디자인 변화를 연계시켜 디자인 교육의 미래 방향에 대해서 연구하였다.

Jackets are regarded as an element used to judge ideas and fashion trends for the age in which they are presented. This article analyzed recent tailored jacket fashion trends by categorizing jackets according to design elements. For this, design elements of tailored jackets were categorized into silhouette, collar and lapel, shoulder and sleeve, and decorative elements. We collected and categorized the changes of 491 jackets that have appeared in collections over the past 5 years. The results showed shoulder and sleeve changes (36.25%), silhouette changes (33.4%), lapel and color changes (12.6%), decorative element changes (11.2%), and no changes (6.5%). Jacket forms with changed shoulders and sleeves appeared as styles that have laterally or vertically expanded the shoulder and arm hole with the production of various sleeve forms. Silhouette changes were expressed through forms such as exaggerated silhouettes of oversized-clothing, silhouettes made through cutting or layering, and the polarization of length. Forms with a changed collar and lapel appeared with polarization trends in which lapels dramatically grow larger or narrower, diverse frontal adjustments using no-collar designs, and the utilization of shawl-collars; in addition, forms with changed decorative elements were expressed with layered decorations such as pockets or collar add-ons, adjustment changes using buttons, ribbons or zippers, and various trimmings. The analysis results show that modern female tailored jackets are being made to realize an exaggerated physical beauty of shoulder, sleeve and torsos to maximize decorative effects through new attempts in design.

This research presents a study for the knowledge-based configuration design development of a RC (remote control) helicopter. Parametric design and knowledge based design concepts are introduced for rapid design changes and analyses using commercial CAD software, CATIA(R) Knowledgeware module. It is crucial for RC helicopter design because it enables rapid conceptual design through instant configuration changes. Positions and dimensions of RC helicopter parts were used as design parameters. As an example, positions of CG(center of gravity) points were traced and plotted as the configuration changes. Further research should be performed in areas of user interfaces and web-based multi-user environments instead of using Excel data sheets.

Since 1993, Korea Institute of Design Promotion has carried out Design Promotion Comprehensive Plan every 4 years and due to the institutes founding purpose the plans are mainly focused on enhancing quality of merchandise goods. However due to social and economic changes now enhancing quality of cultural living through design is becoming important as ever. The purpose of this paper is to find our characteristics and changes in design policies and programs to diffuse design culture in the plans. The researchers have inquired proceeding studies on cultural and design policies and also looked into cases that were carried out in Europe to diffuse design culture. By analyzing EU's Cultural Policies four means were found: Education, Exchange, Participation, and Sharing. The results are as follows. First, in the beginning main focus was to educate people about the importance of design and what good design is, in bureaucratic ways. In the Secondary plan, reaching out to local regions begin to show in order to diffuse design culture that was and still is mainly centered around Seoul. Thirdly plan shows more exchanges but not only limited to domestic regions but international wide. In the Forth plan, participation programs and those engaging design to solve social problems are shown but still not much attention is payed to sharing.
