Following to current interior design that becoming more varied and composite, minimal tendency has also been changed. Furthermore, according to the lapse of time, minimalism, a space design, has been developed in a new look among such complex trends. Therefore, in this study, changes of tendency into a style of minimalism and characteristics thereof shown in interior design amid current of times were carefully reviewed, and local and foreign artists together with their works were investigated and analyzed having focused on the inclination of minimalism displayed in interiors of commercial spaces, especially before or after 2000s by dividing them into distinctive features in connection with space, material and type. It is thought that the interior space under the concept of minimalism will be changed and developed further in a variety of shapes to suit the environments in the current era getting rid of simple physical characteristics.

Presently, rapidly changing and unstable global economic environments demand engineers. Products should be designed to increase profits by lowering costs and provide distinguished performance compared with competitors. This study aims to optimize the design of the power-transmission drive shaft. The mass is reduced as an objective function, and the stress is constrained under a constant value. To reduce the number of experiments, CCD (central composite design) and D-Optimal are used for the experimental design. RSM (response surface methodology) is employed to construct a regression model for the objective functions and constraint function. In this problem, there is only one objective function for the mass. The other objective function gives 1; thus, NSGA-II is used.

This study was intended to suggest the design guidelines of the space for the elderly with dementia. To achieve this, the behavioral characteristics of the elderly with dementia were grasped, and the design cases which were considered and reflected of the behavioral characteristics of the elderly with dementia were examined. Then, the effective space design guidelines which met the behavioral characteristcs of the elderly with dementia were suggested. The behaviors of the elderly with dementia were categorized into cognitive, emotional, and functional behavior. The positive influences of space design on dementia symptom were founded in the planned living environments, accessible and visible location of common space such as living room, soft and homelike interior finishes and lighting, and healing garden. Therefore, the space design for the elderly with dementia should be done on the basis of the dementia symptoms and healing effects.

In the last several decades of 20 century, the user oriented design concept has evolved in more concrete ways, producing POE and UPD(User Participated design). These concepts are ways of achieving the fit between built environments and human needs. These, technique in the digital world has implied and promoted lots of experimental ways to interact with possible users before the construction stages in the design process to reduce the results, stemming from ineffective planning and designing. The purpose of this paper is to show an evaluation technique in the design cycle. An actually designed child care facility was evaluated before construction by potential users. For this purpose, focused group interview was employed.

The word \"permaculture\" is a contraction of \"permanent agriculture\" or \"permanent culture\". Permaculture principles are designed to support (or ensure) the survival of humanity, the earth and all on it, and, to improve our standard of living, Permaculture can be defined as : a design system for creating sustainable human environments that can be (relatively) easily constructed and maintained. The principles of permaculture designs are relative location every element (such as house , rice paddy, road, esc) is placed in relation to each other such that each assists the other : each element performs multiple functions ; each function is supported by many elements : energy efficient planning ; using biological resources rather than fossil fuels : energy cycling on site (both fuel and human energy) : Using and accelerating natural plant succession to establish favourable sites and soils ; poly-culture and diversity of beneficial species for a productive, interactive system ; use of edge and natural patterns for best effect. These principles can be used for any permaculture design, in any climate, and at any scale. There has been very little scientific examination of Permaculture, and as such, it must be viewed as a design philosophy.viewed as a design philosophy.

To analyze the correlation between drivetrain systems and to optimize the vehicle design with satisfying of the initial design objects, the performance sensitivity analysis through the iterative design procedure must be carried out. In this study, effects of the design parameters for the main components of the parallel type hybrid drivetrain system are analyzed by using the developed method of the vehicle performance simulation, and the basis of the optimal selection of the design parameters from the relation of design constraints and required performances is suggested. In driving control of the parallel hybrid vehicle, power split ratio is the most important factor, and the improved drivetrain system can be constructed through the only change of the algorithm for determination of the power spilt ratio, which is strongly applicable to the driving patterns and the environments. Therefore, Various techniques, such as the change of the weighting factors and the range extended algorithm, are suggested and evaluated in this paper.

A product family design has received much attention over the last several decades, since a product family-based development shortens lead-times and reduces cost, as well as increases efficiency and effectiveness of the product realization process. It is challenging work, however, to define the product family design in the heterogeneous product development environments, due to myriads of products related information described in different ways across products in any companies. In this paper, we provided a way of defining product family design framework using formal concept analysis and ontology language. Based on this, the specific product family can be derived by ontological reasoning, and the new product concept can be also expanded in the framework. The proposed framework is formalized using OWL (Web Ontology Language) and implemented in $Prot{\acute{e}}g{\acute{e}}$. Actual product family design algorithm is carried out using FaCT++ engine, a plug-in to $Prot{\acute{e}}g{\acute{e}}$, and the benefits of the proposed method are also demonstrated through a case study.

Owing to the mass-housing policies of high-density and high-rise, the residential environments in Korea have come to be uniform and monotonous. Nevertheless, the design competitions introduced for the first time in 1980s have played significant roles in developing the fresh ideas and concepts in housing design. It is important to review the ideas played proposed in competitions until now in order to spread them into other housing developments. In this context this study classified the types of unit plan and analyzed their design characteristics in the proposals of housing design competitions in 1990s.

Our society is rapidly digitalizing. The effects of his digitalization are very diverse and one of them is that our living environments are changing. Many routine places which certain activities have been taken places are changing. For example, home office, education at home using internet, home shopping, internet banking, and so on. These facts cause the home to be extended and digitalized. That is, as our living patterns are changing, the housing needs are also changing. The purpose of this study is to graspe the digital related housing needs of the residents and suggest the directions of the digital home design. The subjects were 400 housewives who lived in 85m2 sized multi-family houses in Busan. They were relatively young in their age, had high education level, and middle income. On the base of their demands, the digital home designed as follows would be desirable: 1) safe and secure design and digital system, 2) design to improve residents' health and encourge family interaction, 3) human, warm, and soft interior mood, 4) the space composition different from the existing one.
