The purposes of this study are to find out the factors of consumers attitude toward Fashion luxury products; to identify the effects of demographics to influence on consumer's attitude toward fashion luxury products; to identify the effects of the attitude toward fashion luxury to influence on the concern for fashion luxury. The subjects were Korean 445 women from 20's to 50's living in Seoul. The mean, ANOVA, factor analysis, regression analysis, Duncan test were used for statistics analysis. The results are as follows; Seven factors of the attitude toward fashion luxury products were identified: the involvement for fashion luxury, the duality of fashion luxury, the negative response toward the consumption of fashion luxury, the luxurious aspect of fashion goods, the traditional value of fashion luxury, the rarity of fashion luxury. Among demographics, age and income influenced on fashion luxury products involvement, the quality of luxury products. The perception of good quality and hedonic consumption of luxury good influence highly on the involvement for the luxury products.

The purpose of the study is to identify the designers' and the patterner's pattern making, draping and the use of dress form in domestic companies of designer's brand to present basic information for effective pattern works. It turned out that the designer brand companies at home use flat pattern and draping at the same time rather than draping only The effects of the use of draping lies in unique designs and elastic materials, which seems proper phenomena for the current design trend such as high duality and diversification. But, draping has such problems that the pattern takes long time to be finished and that the staffs don't acquire well the needed skills due to the lack of draping education. To secure the high added value of fashion, it is required to develop education programs for new skills and to apply draping actively. Also, it requires an educational system in which practice oriented skills are cultivated, and efficient investment into apparel business.

Let A be a co-Poisson Hopf algebra with Poisson co-bracket $\delta$. Here it is shown that the Hopf dual $A^{\circ}$ is a Poisson Hopf algebra with Poisson bracket {f, g}(x) = < $\delta(x)$, $f\;{\otimes}\;g$ > for any f, g $\in$ $A^{\circ}$ and x $\in$ A if A is an almost normalizing extension over the ground field. Moreover we get, as a corollary, the fact that the Hopf dual of the universal enveloping algebra U(g) for a finite dimensional Lie bialgebra g is a Poisson Hopf algebra.

To increase the overall utility and decrease the link delay and power consumption, a joint optimal cross-layer design of congestion control at the transport layer, link delay at the data link layer and power allocation at the physical layer for mobile ad hoc networks is considered in this paper. As opposed to previous work, the rate outage probability in this work is based on exactly closed-form; therefore, the proposed method can guarantee the globally optimal solutions to the underlying problem. The non-convex formulated problem is transformed into a convex one, which is solved by exploiting the duality technique. Finally, simulation results verify that our proposal achieves considerable benefits over the existing method.

The purpose of this study is to provide for the basic data useful to the high quality knitwear production. For this purpose, knit promotions that product knitwear for 20 age ∼ 30 middle age women were sampled to survey the fabric planning and production·quality management of knitwear, and their directors were surveyed through direct interviews. Data is processed by a computer(SPSS) and analyzed by using frequency, percentage, mean. The results of this study are as fellows. 1. Most of the sample companies were getting smaller or pettier in terms of capital, number of employees. 2. Knit promotions were universally using acrid and wool as knit fabric. 3. Knitwear tended to be producted much in knit promotions. 4. It is needed to use high quality fabric and perform careful sewing for knitwear quality rising.

This paper presents an improved optimal power flow algorithm, which solves an optimization problem with equality constraints with converted inequality constraints. The standard OPF and the penalty function method should do reconstructing active constraints among the inequality constraints so that the activation of the inequality constraints has been imposing an additional burden to solve OPF problem efficiently. However the proposed algorithm converts active inequality constraints into the equality constraints in order to preclude us from reconstructing the procedures. The effectiveness of the new OPF algorithm is validated by applying the IEEE 14 bus system.

Generally, the repeater in CDMA(Code Division Multiple Access) included HPA(HI-Power Amplifier) to amplifier communication signals. Also, HPA contained PD(Predistortor) to maintain the linearization of amplifier characteristics A configuration component of PD have been used electricity nonlinear devices such that diode. But this diode takes many influences at the circumstance temperature. Consequently, st can't maintain output linearization, and drop the communication Duality. The manufacturer set bias of the circuit to the manual at the first out of ware-house low. But the Q-point changes according to the change of the high temperature or low temperature. Therefore, we designed a system to maintain the Q-point by FDM(Fuzzy Decision Maker) in this paper.

Disease susceptibility is linked to nutritional status for a wide range of human and animal diseases. Nutritional status can influence both resistance (ability to resist the pathogen) and resilience (ability to tolerate or ameliorate the effects of the pathogen). This review focuses on the nutritional modulation of gastro-intestinal nematode infection in domestic ruminants, primarily sheep. It highlights the duality of the adverse consequences of infection on host nutritional status and the adverse consequences of poor host nutritional status on resistance to infection. Central to both phenomena is the complex, gut-based immune response to gastrointestinal nematode infection. The potential for strategic nutritional supplementation to enhance host resistance and resilience is reviewed together with recent findings on responses to increased ME supply, and long term effects on host immunity of short term protein supplementation.

Recently, the research and discussion to set up the evaluation standard for nor impact noises in multistory residential buildings has been vividly carried out In Korea. Therefore, the correlation between the methods and auditory responses was investigated through this research to investigate the applicability of the L index evaluation method and the reverse A characteristics evaluation method that are listed in JIS A 1419 since Japanese circumstance are similar to Korean after evaluating the duality of Korean multistory residential buildings. As a result, it was found that the correlation between the value resulted from L index evaluation and the value from reverse A characteristics evaluation is high. In addition, it was also revealed that human responses to each Impacter was similar. Consequently, it is considered th:31 the tendency about the two methods would be similar.
