첫번째 질문-포용적 디자인을 진정으로 포용적으로 만드는 방법은 무엇인가. 대부분의 포용적 디자인 제품들이 사용자들에게 그다지 매력을 주지 못하는 이유는 디자이너들이 제품의 사용성의 개선에 치중하면서도 제품과 사용자를 연결해 주는 감성적 가치를 간과하기 때문이다. 디스플레이와 키보드를 크게 하는 등의 사용성의 개선책은 때로 제품을 매력이 없고 관심을 끌지 못하게 만들어 결과적으로 원래의 의도와는 달리 포용성을 충족시키지 못하게 되게 된다. 감성적 디자인이란 단순히 재미있는 제품을 만드는 것이 아니라, 사용하기 즐거운 제품을 만드는 것을 의미한다. 긍정적인 감성적 디자인은 제품에 대한 호감을 증가시켜서 사용자로 하여금 제품에 대한 연결감을 고양시키고, 이러한 감성적 연결감은 제품을 사용하는 것을 즐겁게 할 뿐만 아니라, 사용 방법을 배우는 것 조차 즐겁게 만든다. 또한 제품에 대한 주의를 높이고 지루함을 줄여서 사용성에 따르는 많은 문제를 해결해 준다. 더 많은 사람이 즐겁게 사용한다면 그 제품의 포용성은 더욱 높아질 것이다. 두번째 질문-포용적 디자인은 혁신적인 상품성이 있을 수 없는가. 대개의 포용적 디자인 제품은 혁신적이지 못하고, 따라서 새로운 시장 기회를 만들지 못한다. 감성적 접근방법이 사용자 측면의 가치를 높이는 일이라면, 혁신적 디자인 접근 방법은 시장에서의 가치를 높이는 일이다. 이는 더 많은 기업의 포용적 디자인 제품의 개발을 촉진시키게 된다. 본 논문에서는 포용적 디자인에서의 감성적 디자인 방법의 효과를 조명하고, 감성적 디자인 접근 방법이 포용적 디자인 제품을 혁신적으로 만들 수 있는 가능성을 다룬다. 또한 제시된 디자인 프로세스를 통하여 이러한 과정의 사례를 보여준다.

The purpose of this study was to investigate the influence of luxury brand value on luxury brand preferences according to chemyon(social-face). For data collection, research questionnaires were responded by 222 females over 20 years old consumers living in Pusan and Ulsan. The collected data were analyzed using SPSS 14.0 for windows Package by frequency analysis, the factor analysis using Varimax, reliability analysis, multi-regression analysis, and chow-test. The results of this study were as follows: First, concerning the worth of luxury brands that qualify value, conspicuous value, unique value, and emotional value significantly affected the consumers' luxury brand preferences. On the other hand, only social value of the luxury brand did not have a significant effect on the consumers luxury brand preferences. Second, the study was to investigate whether the luxury brand value has an effect on the brand preferences according the consumer's chemyon or not. The results showed different effects of perceived values on luxury brand preferences between the low chemyon group and the high chemyon group. The high chemyon group had an effect on conspicuous value, social value, and emotional value, while the low chemyon group had an effect on quality value for luxury brand preference.

This research studied robust design of composite structure under combined loading of bending and torsion. DOE (Design of Experiment) technique was used to find important design factors. The results show that the beam height, beam width, layer thickness and stack angle of outer-layer are important design parameter. The $2^{nd}$ DOE and RSM (Response Surface Model) were conducted to obtain optimum design. Multi-island genetic algorithm was used to optimum design. An approximate value of 6.65 mm in deflection was expected under optimum condition. Six sigma robust design was conducted to find out guideline for control range of design parameter. To acquire six sigma level reliability, the sigma level reliability, the standard deviation of design parameter should be controlled within 2.5 % of average design value.

The purpose of this study is to develop an optimal performance design ova concrete median barrier using the design of experiment and crash simulation which is done by Pam-Crash, one of the commercial crash simulation software. A formula of characteristic value was suggested to obtain an optimal performance design considering all of von Mises stress, volume and acceleration at center of gravity of a heavy truck. An optimal design of a concrete median barrier was obtained by the analysis of variance based on design of experiment and crash simulation. A crash simulation with the optimal design was accomplished in order to verify the suitability of the suggested formula and the proper application of the design of experiment. The obtained optimal design was satisfied for a domestic design regulation of a concrete median barrier.

This paper presents the optimal design of Robot-Arm part use Design of Experiment(DOE). The DOE(Design of Experiment)was conducted to find out main effect factors for design of Robot-Arm part. In this design of Robot-Arm, 5 control factors include numbers of 4 level are selected and we make out L16 orthogonal array. Using this orthogonal array, find out optimal value and main effect factors of object function for design of Robot-Arm part by 16 times of test. We evidence this optimal value by using CATIA V5 Analysis.

This report investigates the stress distribution according to the location and shape change of the circular hole for the lightweight design of the cross beam of a railway passenger car and studies the lightweight design. To design a lightweight cross beam with a circular hole, we selected the non-circular crossbeam as a basic model, examined the stress distribution and displacement by position and determined the location, shape, size and quantity of the hole for light weight. We analyzed the effects of the position and shape of the hole on the maximum equivalent stress and displacement. The influencing factors were set as the design parameters, and the stress value was examined according to the variation of each variable. By considering the stress value according to the change of each variable and selecting the design parameter with the narrowest scattering value of the stress at each position of the hollow cross beam with various hole positions and shapes, we studied a cross beam with a circle hole under identical load condition to have an equal stress distribution to that of a non-circular cross beam.

뢰성에 기반한 한계상태설계법은 국제표준화기구인 ISO뿐만 아니라 국내의 각종 건설관련 기준에서도 적용되는 등 국내외적으로 기존 허용응력설계법을 대체하고 있는 실정이다. 본 논문에서는 국내에서 건축물의 기초로 많이 사용되고 있는 PHC 매입말뚝을 대상으로 한계상태설계법의 일종인 LRFD 설계정수를 제안하였다. PHC 매입말뚝의 LRFD 설계정수를 제안하기 위해 81개의 현장 동재하 시험자료와 이들 말뚝에 대한 지지력 설계(Meyerhof 설계법, SPT-CPT 전환 설계법) 자료를 분석하고 목표 신뢰도 지수 2.33과 3.0에 대해 하중저항계수를 제시하였다. PHC 매입말뚝의 저항계수는 목표 신뢰도 지수에 따라 Meyerhof 방법, SPT-CPT 전환법은 각각 0.36~0.44, 0.24~0.31을 나타내었다.

An extreme value analysis (EVA) is essential to obtain a design value for highly nonlinear variables such as long-term environmental data for wind and waves, and slamming or sloshing impact pressures. According to the extreme value theory (EVT), the extreme value distribution is derived by multiplying the initial cumulative distribution functions for independent and identically distributed (IID) random variables. However, in the position mooring of DNVGL, the sampled global maxima of the mooring line tension are assumed to be IID stochastic variables without checking their independence. The ITTC Recommended Procedures and Guidelines for Sloshing Model Tests never deal with the independence of the sampling data. Hence, a design value estimated without the IID check would be under- or over-estimated because of considering observations far away from a Weibull or generalized Pareto distribution (GPD) as outliers. In this study, the IID sampling data are first checked in an EVA. With no IID random variables, an automatic resampling scheme is recommended using the block maxima approach for a generalized extreme value (GEV) distribution and peaks-over-threshold (POT) approach for a GPD. A partial autocorrelation function (PACF) is used to check the IID variables. In this study, only one 5 h sample of sloshing test results was used for a feasibility study of the resampling IID variables approach. Based on this study, the resampling IID variables may reduce the number of outliers, and the statistically more appropriate design value could be achieved with independent samples.

The major aim of this study was to find out that the relation between consumers value and experience quality toward purchase intention in addition to the influence of the consumers value and experience quality on the effects of scarcity message types collaboration using limited edition in global SPA brand. As a result of an empirical analysis, it shows that consumers value and experience quality are co-related to the intention of purchase, especially, brand familiarity and reputation influenced scarcity valuation in the affirmative and both emotional value and epistemic value influenced the intention of purchase under scarcity message. The moderating effect of consumers value and experience quality however, turns out to be not significant although its effect is directionally supported that is purchase intention was high when scarcity message is shown. Moreover, emotional epistemic group was influenced by scarcity message so we found that consumers value is changed to emotional with subjective. This result indicates that we need the scarcity message type reflecting the characteristics of consumers value and experience quality to increase customer's purchase intention.
