This study conducted a survey to find out atopic dermatitis patients' required performance and preference in design factors to develop spring/summer(S/S) knitwears preferred by atopic patients. On the platform of achieved information from statistical analysis, S/S knitwear samples for atopic patients were designed and constructed with cotton/Seacell(R) blended yarn, And subjective wearing sensation were evaluated comparing the samples and the commercial products made with cotton/chitosan blended yarn, trying to help producing more comfortable S/S knitwears for atopic patients. SPSS 12.0 program was used for frequency analysis, Chi-square analysis, ANOVA, and Duncan test. The result was as follows; For comfort of S/S knitwears, atopic patients most considered skin care property. Atopic patients preferred simple and basic knitwear in light color with thin and soft fabric such as plain knit. The preferred style was that 'appropriately fit with suitable ease'. They also preferred 'closed front'; 'boat neckline' and 'V neckline'; 'raglan sleeve' and 'set-in sleeve'. For hem trim, they preferred 'rib' structure. Male preferred simple and plain style with 'round collar' and 'tubular or rib trim", while female preferred sophisticated and characteristic style with 'set-in sleeve' with 'rib trim'. Under the circumstances with insufficient functional knitwears developed, this study tried to develop comfort S/S knitwears for atopic dermatitis patients and the developed knitwears showed as good as or better performance in wearing feeling, fitting, and appearance than the previously developed functional goods.

The purpose of this paper lies in the comparison of the body types between the subjects of Korean women in their 60's living in Russia and China. The findings are as follows. 1. The comparison of 80 items in physical measurements between the Korean women in their 60's living in Russia and China resulted in the differences in 57 items. While the height items including stature between them showed negligible differences, most of the length items relating to width, thickness, circumference, and obesity showed differences, which were big. 2. The analysis by using the physical measurements showed the differences in the number of the elements constituting the body types of the Korean women in their 60's, as 13 for those living in Russia and 11 for those living in China. 3. The cluster analysis for the comparison of the body types of each group, by categorizing the body types, produced three types for both groups. Koreans living in Russia were grouped as those with the short stature and light weight, the medium stature and medium weight, and the tall stature and heavy weight. Koreas living in China were classified as those with the short stature and medium weight, the tall stature and light weight, and the tall stature and heavy weight.

The development of modern transportation technology has required many people in spaces (such as vehicle seats, airports, and train stations) for long periods. The public seats provided in these places are manufactured in a standard size; however, fatigue sets in if the seats are unsuitable for the person's physical size. For this reason, this study developed an air cushion vest that would enhance the comfort of vehicle seats. Passengers in vehicles, trains, airplanes, and buses were observed and surveyed to understand the demand for seat comfort. Our analysis found that the greatest source of discomfort was involuntary nodding of the head while asleep and discomfort around the waist area. For this reason, the air cushion vest was designed to support the head and the waist. The neck cushion of this vest was designed to strengthen head support to counter forward nodding because existing commercial neck cushions had no support for forward nodding. For the waist cushion, at lumbar and below-lumbar parts were chosen as the key parts to be supported, the cushion was designed to contain air at those parts. To cover the embedded waist cushion, the vest was designed to be long. The closure was constructed with zippers from the neck to waistline, and with invisible snaps from the waistline to the hemline so that the wearer could open them easily while seated. A subjective comfort evaluation was conducted to verify the effectiveness of the developed vest. In the test, the developed cushions received a better evaluation than cushions currently available on the market. The volume of the vest could be adjusted by the inflow and outflow of air. It was proven that the vest was effective in terms of comfort and portability. This shows that the developed vest could enhance passenger comfort while sitting on vehicle seats.

The main objective of this study was to examine how Chinese consumers' perceptions toward Korean apparel products have changed over the years. Specifically, motives for purchasing Korean apparel products, information sources, purchase criteria and evaluation on Korean apparel products were investigated. Data were collected in 2002, 2003, 2005, and 2007 from young female Chinese in Beijing, China during the months of June and July. A total of 603 questionnaires were collected and 578 were used in the final analysis. The results of two-way analysis of variance by year and purchase experience indicated that in overall, purchase motives and importance of various information sources changed greatly over the years, while evaluation on Korean apparel products have remained relatively stable. In comparison to the longitudinal changes in Chinese perception toward Korean apparel products, Chinese consumers' perception toward Korean apparel products did not differ significantly in most of variables according to purchase experience.

Piceatannol (trans-3,4,3',5'-tetrahydroxystilbene), a natural stilbene, is an analogue of resveratrol. Although recent experimental data have revealed the health benefit potency of piceatannol, the molecular mechanisms underlying the anti-cancer activity have not yet been studied in detail. In the present study, the further possible mechanisms by which piceatannol exerts its pro-apoptotic action in cultured human lung cancer A549 cells were investigated. Exposure of A549 cells to piceatannol resulted in growth inhibition and induction of apoptosis. Apoptosis induction of A549 cells by piceatannol showed correlation with proteolytic activation of caspase-3, -8, and -9, and concomitant degradation of activated caspase-3 target proteins such as poly (ADP-ribose) polymerase, phospholipase C-${\gamma}1$, ${\beta}$-catenin, and Inhibitor caspase-activated DNase. The increase in apoptosis by piceatannol treatment was also associated with an increase of pro-apoptotic Bax expression and decrease of anti-apoptotic Bcl-2 and Bcl-xL expression, and caused down-regulation of the inhibitor of apoptosis protein family members and up-regulation of Fas and Fas legend. In addition, piceatannol treatment markedly inhibited the expression of mRNA and proteins of inducible nitric oxide (NO) synthase, and the levels of NO production were progressively down-regulated by piceatannol treatment in a dose-dependent fashion. The results indicate that piceatannol may have therapeutic potential against human gastric cancer cells.

This study was performed to develop a video based system which can be used to measure the averaged fish size in a non-intrusive fashion. The design was based on principles of simple stereo geometry, incorporated fish dimensions weight relationships and took into consideration fish movement to lower system costs. As the fish size is an important factor that impacts the economy of an aquaculture enterprise. Size measurements, including fork length, width or height, girth, thickness and mass, can be used to determine fish condition in the fish farm, so the averaged fish size of fish cage needs to consistently monitor in open ocean aquaculture cage. A precision of ${\pm}3%$ for replicate length measurements of a 60cm bar is obtained at distances between 2.0 and 6.0m, and the mean fork length and mean swimming speed of bluefin tuna were estimated to 48.8cm and 0.78FL/s, respectively.

Composite draw textured yarns(DTY) and air jet textured yarns(ATY) with hollow PET filament have been used for making high emotional fabrics including light weight sports wear garments. This study investigated effect of hollow composite yarns and fabric structural parameters to the comfort properties related to the moisture and thermal transport phenomena for the composite fabrics made of DTY and ATY with hollow PET filament. Wicking property of hollow composite fabric was superior at the high pore size fabric and was not influenced by fabric cover factor. Wicking property of the fabric with ATY was better than that of the fabric with DTY. On the other hand, drying rate of fine pore sized fabric was shorter than that of large pore sized fabric and drying rate of high multi yarn fabric with low cover factor and small pore size was superior than that of hollow composite fabric. The pore size of the fabric was dominant factor in the air permeability and thermal conductivity of hollow composite fabric. High pore sized fabric showed high air permeability and thermal conductivity of hollow composite fabric was nonlinearly inversely proportional to pore size of the fabric.

UV irradiated acrylic pressure sensitive adhesives(PSAs) are prepared to be used for thermal pad in plasma display panel(PDP). The effect of the chemical structure of side-chain in comonomer and of crosslinking agent on wet-out property of acrylic PSAs in wide temperature range were investigated. The correlationship between viscoelastic behavior and adhesion properties, such as tack and peel strength, was also studied. The experimental results supported that wet-out and adhesion properties of acrylic PSAs were enhanced inversely proportional to side-chain length of comonomer in wide temperature range. The peel energy clearly increased in acrylic PSAs prepared by using di(ethylene glycol) dimethylacrylate (DEGDMA) for crosslinking agent. The results might be due to the difference in the glass transition temperature and viscoelastic behavior of acrylic PSAs.

Personal appearance attitude about the ideal beauty is influenced by the context of the culture one belongs to. In a cultural sphere the higher public self-consciousness individuals have then the more sensitive one would be to the sociocultural pressure about thinness and thus the higher the expectations about the ideal appearance. Accordingly, in that culture one would have more body shame when they do not reach the ideal beauty standard. This study examines the difference between Korean and German culture, with a focus on the age group of university students who are especially sensitive to aesthetic consciousness. The results are as follows: There were differences of public self-consciousness, perceived sociocultural pressure, appearance internalization, appearance awareness and body shame between the two cultural spheres; in addition, Korean female university students were significantly higher in all the variables when compared to German female university students. The higher public self-consciousness and perceived sociocultural pressure then the higher the internalization of the ideal appearance; the ideal appearance awareness increased the body shame. In the case of the German female university student group, public self-consciousness influenced body shame directly; however, in case of the Korean female university student group public self-consciousness were not directly affective. Rather, perceived sociocultural pressures directly affected body shame and showed the difference between the cultural spheres. Finally, in regards to the direct effect about body shame, the German female university student group noted the influence of public self-consciousness as the most significant; however, the Korean female university student group noted the influence of sociocultural pressure as the most significant.
