One of the main problems in 3D shape measuring systems that use the triangulation of line-shaped laser light is precise center line detection of line-shaped laser stripe. The intensity of a line-shaped laser light stripe on the CCD image varies following to the reflection angles, colors and shapes of objects. In this paper, a new center line detection algorithm to compensate the local intensity variation on a line-shaped laser light stripe is proposed. The 3-D surface shape measuring system using the proposed center line detection algorithm can measure 3-D surface shape with enhanced measurement resolution by using the dynamic shape reconstruction with adaptive pattern clustering of the line-shaped laser light. This proposed 3-D shape measuring system can be easily applied to practical situations of measuring 3-D surface by virtue of high speed measurement and compact hardware compositions.

Denim has been one of the most favored clothing item among young people regardless of regional difference. This study compared the styling of women's denim fashion in two Asian metro-cities, Seoul and Beijing, in order to understand how differ the fashion taste of both cities. Data was collected by taking photos of young women who wear denim clothing at the main streets of downtowns or famous shopping areas of both cities from the July of 2004 till the April of 2005. A total of 524 photos(Seoul 242, and Beijing 282) were put into content analysis. Results showed that there were several similarities and differences in denim styling between two cities in terms of the most widely worn denim items and the coordinate items, and the favored colors, silhouette, details of denim pants and the coordinate items. In Seoul, women favored denim look with little detail, fitted silhouette, and in more formal image. A few denim styles prevailed in each season which reflect current denim fashion trends. Meanwhile a wide variety of denim styles were found at Beijing without dominant denim trends, which means Beijing women put more emphasis on personal expression of their fashion taste instead of just following fashion trends.

Digital is the main topic of 21C design. Experts analyzed that pop art and related cultural products are becoming popular as digital generations of twenties to forties are centered of new art culture. This survey is to suggest the differentiated jewelry products which are out of the existing products as combining the embodiment of various colors by using celebrities who are taken kindly to and the lenticular which can be image converted through an optical illusion. As public's living standard is getting improved, design elements would come into the spotlight. Therefore, this research is expected to work as the part of an epoch-making design in the jewelry industry by extending the design field.

The purpose of this study was to examine visually impaired people's clothing behavior, using a qualitative approach. The results are intended to be used as baseline data to make an instrument that can measure the factors that have an effect on visually impaired people's clothing needs from the perspective of environmental and social relationship contexts. This study was made through in-depth interviews with people with grade-1 visual impairment, and the results were as follows: First, when purchasing clothing, they were accompanied by trusted people, and chose trusted brands and trusted products. They spent as little time as possible, did not try on many clothes, and they preferred colors, designs, and purchase methods that carried as low a risk as possible. Second, they wanted basic product information and simple procedures when purchasing and using clothing products. Third, they were able to manage their own clothes themselves. However, there was insufficient laundry information available. Fourth, the main reason why visually impaired people took care of their appearance was that they wanted to look neat and clean to be respected by others. Based on the study results, it is necessary to provide information on clothing to improve quality of life and welfare and thus ensure visually impaired people's independence.

For a connected graph G, an r-maximum edge-coloring is an edge-coloring f defined on E(G) such that at every vertex v with $d_G(v){\geq}r$ exactly r incident edges to v receive the maximum color. The r-maximum index $x^{\prime}_r(G)$ is the least number of required colors to have an r-maximum edge coloring of G. In this paper, we show how the r-maximum index is affected by adding an edge or a vertex. As a main result, we show that for each $r{\geq}3$ the r-maximum index function over the graphs admitting an r-maximum edge-coloring is unbounded and the range is the set of natural numbers. In other words, for each $r{\geq}3$ and $k{\geq}1$ there is a family of graphs G(r, k) with $x^{\prime}_r(G(r,k))=k$. Also, we construct a family of graphs not admitting an r-maximum edge-coloring with arbitrary maximum degrees: for any fixed $r{\geq}3$, there is an infinite family of graphs ${\mathcal{F}}_r=\{G_k:k{\geq}r+1\}$, where for each $k{\geq}r+1$ there is no r-maximum edge-coloring of $G_k$ and ${\Delta}(G_k)=k$.
