  • In the architectural design technologies being changed recently, there is the study to develop the way that will enable the designers to get access logically to the processes of deciding the values of design factors which depend on the experience of the designers. This study, which is one part of those studies, has been carried out to develop the model that can decide the values logically for the design factors having the character that the design values are changed by the time variation out of design factors involved in the building energy saving design. As a result, the structure of the decision model which can decide the design values logically from the computer simulation that solve the problem by interpreting the real world as the probability distribution, has been established through this study. For the application and verification of these decision model, the case study has been carried out for the outdoor climate factors that stand for the design factors having the time variation.

  • In this study, we develop and propose damping correction factors for the Korean standard design spectra. The newly proposed Korean standard design spectra has been given only for 5% damping ratio. But in practice, engineers need design spectra for damping values other than 5%. To obtain design spectra for various damping values from the standard spectra, damping correction factors are derived. These factors modify the shape of design spectra in accordance with the damping ratio. Response spectra for various damping values are calculated from the earthquake records that had been used to calculate standard design spectra. They consist of 55 records from 18 earthquakes occurred in overseas intraplate regions and Korea. The regressed spectra for the damping values ranging from 0.5% to 50 % are compared with standard spectra at three regions acceleration, velocity and displacement sensitive regions. The regression analysis of these data rendered formula for damping correction factors. Finally, a single formula for damping correction factors is recommended that is valid for both horizontal and vertical design spectra and that is applicable to the entire range of periods. One thing to note that recommended damping correction factors is valid for the design spectrum of the rock grounds because the design spectra was developed based on the earthquake records of the rock ground.

  • Design policy in Korea has been dealt as one of the industrial policies in economic policies, and it can be classified as government driven. A problem derived from this is that previous design policies have only pursued creating material values, and have overlooked the emotional values of design, such as creating cultural identity of Korea and cultural independence through it. Therefore, a new mindset of 'Cultural Era of Design' and a new role of 'Designers as Producers of Culture' must be in the strategy and system for supporting the design in Korea. This study can be divided into three major parts. First part compares and examines current design policies of Korea to seek more suitable design policies. Second part suggests a new direction for design policy by analyzing the ideas and cases of such policies. Third part surveys designers and people in related fields to collect opinions about design policies in Korea to propose directions for new design policies and ways to evaluate them. The object of this process is to find out how they, in the center of design and cultural industries, see and follow the policies. It will aid the narrowing of perceptual gap between them and the developers of policies.

  • This research is to understand luxury consumption values for luxury consumers. The aims of this study is to identify their luxury consumption values and the effects of the values on the perceived acquisition value. This study also divided data into two groups according to the difference between reservation price and actual price; positive reservation price group, negative reservation price group, and analyzed the effects of the values on the perceived acquisition value between two groups. In this study, we used structural models equation and results presented that the conceptual model was a good fit to the data. The empirical results suggested four dimensions of luxury consumption values; symbolic value, innovative design value, quality value and origin value. There were positively significant effects of symbolic value and quality value on the perceived acquisition value. The effects of innovative design value on the acquisition value was significantly negative. Two groups categorized by reservation price depicted the differences on effect levels of symbolic value, innovative design value, and quality value on the acquisition value perception.

  • The existing market patterns and social structures have been changed according to the trends of digital and informational society of the 21st century. The characteristics of the consumption market is that the balance of power moves from enterprises to consumers. As consumers’ demands are diversified according to life quality enhancement, many products are based on main aspects of human experiences, emotions and values. Standardized functions and services of products cannot capture consumers to a great extent any more. A notable aspect is that consumers want products or services that can oner movable experiences. Future products must appeal to emotion, not to reason of consumers. Now consumers purchase styles, experiences and stories contained in products, not products themselves. That is, the key to decision to purchase products is the satisfaction of emotional values. Users'emotions diversified due to the development of industrial designs demand the development of new designs that can represent new trends of users. User-centered values imply the change of people's purchasing trends. This indicates that there is a need to change physical aspects such as price or functions into individual emotions and characters. In addition, studies are required on design concepts to pursue new emotional values, apart from functional type designs. It is time for designers to suggest initiative and rational directions for this changing era.

  • In this study, we attempted to expect the mechanical characteristics of the wool fabrics by knowing the yarns. Moreover, we believe that we could apply these results to fabric design. We investigated the relationship between the mechanical characteristics of yarns and fabrics. As results, we have found that bending rigidity, bending hysteresis, compressional energy and compressional linearity between yarns and fabrics had correlated more than r=0.5. Also, the correlation between regression and experimental values is r=0.5 in stiffness while it is r=0.67 in fullness. And regression values were larger than experimental ones in stiffness, but were not in fullness. The correlation between regressional and experimental values had 0.63 in THV. According to the study, it is possible to apply it to fabric design when our predicting the primary hand and the total hand values of the fabrics from the mechanical characteristics of the yarns.

  • Computer simulation of buildings and solar energy systems is being used increasingly in energy assessments and design.. Building designers often now predict the performance of buildings simulation programmes that require hourly weather data. However, not all weather stations provide hourly data. Climate prediction models such as HadCM3 also provide the daily average dry bulb temperature as well as the maximum and minimum. Hourly temperature values are available for building thermal simulations that accounts for future changes to climate. In order to make full use of these predicted future weather data in building simulation programmes, algorithms for downscaling daily values to hourly values are required. This paper describes a more accurate method for generating hourly temperature values in the South Korea that uses all three temperature parameters from climate model. All methods were evaluated for accuracy and stability in terms of coefficient of determination and cumulative error. They were compared with hourly data collected in Seoul and Ulsan, South Korea.
