The recent fashion trend of knit wear is now changing to the various fibrous color combination which emphasizes the plain texture. It supports the human body curvature which is influenced by the slim style of woven wear. In this research work, the general characteristics and knit wear fashion trend are studied. The metallic fiber and fancy yarn are used widely as fiber materials for knit in nowadays. However, the light and functional materials are preferred. The general characteristics of knit which gives the feeling of light and warm are still prevailing using pure wool, kid mohair, and mixed wool with polyester. In order to provide the soft touch feeling, smoothness of fine fiber, and feeling of sponge, several kinds of finishing techniques such as bulky, felting, bonding, and quilting process are usually adopted. The knit wear fashion trend is mainly consisted of the basic design items, and it gives the feeling of luxurious and elegance. The more youthful feeling is adapted for the general style of knit wear of the certain target age. The woven wear trend such as season color, line and pattern are applied in knit wear trend in recent days.

Organic semi-conductive materials have characteristics such as the advantages of easy formability, low-cost and diversity along with moderate semi-conductive properties. In this paper, we developed a flexible organic-inorganic hybrid solar cell fiber. First, we made a solar cell on the glass and attached the solar cell on the glass fiber similarly. In the latter case, thermal deposition method was employed in order to effectively apply ITO onto fiber surface. The amount of ITO was controlled by varying the temperature from 25, 150 to $300^{\circ}C$. Optimum result was obtained at $150^{\circ}C$ where maximize the deposition amount without significant decomposition of ITO. Despite of maximum open circuit voltage of 0.39V, the resulting current was quite unstable and weak, limiting realistic applications. It was, however, concluded that the flexible solar cell fiber developed showed a possibility of low-weight application from functional clothing for military to space suit mainly due to flexibility and thus wear ability.

para-Aramid fibers were treated by low-temperature plasma to improve the adhesion. The surface of para-aramid fibers were treated with gaseous plasma of several discharge power and treatment time in oxygen gas at 1Torr pressure. The treated fibers at low-temperature plasma were taken oxygen-containing functional groups and micro-crator on the surface. The modified fibers were measured by dynamic contact angle analyzer and XPS(X-ray photoelectron spectroscopy). The Interfacial adhesion properties of aramid fabric and polyurethane resin were determined by T-peel test. The surface of aramid fibers were observed by FE-SEM photographs. It was found that surface modification and chemical component ratio of the aramid fibers were improved wettability and adhesion characterization.

Cracks are typical defects that occur in concrete structures. When cracks occur in the structure, durability reduction, concrete neutralization, and steel corrosion cause functional safety problems. In order to prevent such cracks, surface repair method is performed for cracks smaller than 0.3 mm and rechargeable method is performed for cracks larger than 0.3 mm. However, even if it is applied by the surface repair method at less than 0.3 mm, re-leakage cracks continue to occur. Recently, the Supreme Court ruled that the rechargeable method should be applied to cracks less than 0.3mm in order to reduce the occurrence of defects. However, it was considered that the repair fees were too high relative to the observed defect rate, resulting in a necessitation of modifying the existing construction analysis administration standards. This study analyzes the differences in the subjective views on the durability degradation with regards to surface repair methods in concrete structures.

The purpose of this study was to the characteristics of the interior space composition for luxurious apartments and the trend of interior design. Surveying visits were made to 30 model houses for which individual apartments of 8 million Won or more per pyeong (about 3.30 square meters) were on sale from December 1999 through November 2000 in Seoul and suburb area, pundang. The major finding were summarized as follows; (1) The characteristics of the planes indicated that the living-room separation type accounted for the majority, which was not generally different from common apartments. The master zone divided several room. The main room which conventionally played the roles of the family gathering space and the second room shared by family members, was designed exclusively for husband and wife. Distinctively separated from the other spaces, it was to be used for personalized space, together with bathroom for the couple, dressing room, or study. Attempts were made for the high-class apartments to get away from the common uniformed apartments, such as the yard-type balcony or the second entrance in consideration of the moving path. (2) The characteristics of the interior designs showed that the detailed attention was paid to every composing element for the emphasis of the high quality image. The factors determining the quality were finishing materials, kitchen furniture, hygienic ceramics, electrical appliances water supply equipment, or functional storage closet.

The objective of this study was to determine effects of humic acid (HA) and blueberry leaf powder (BLP) supplementation in pig feed on productivity, blood profiles, and meat quality characteristics of longissimus muscle. The experimental design included six treatments: 1) CON, no addition; 2) T1, BLP 0.1%; 3) T2, BLP 0.2%; 4) T3, humic acid 2%; 5) T4: humic acid 2%+BLP 0.1%; and 6) T5: humic acid 2%+BLP 0.2%. HA and BLP supplementation in pig feed significantly increased average daily feed intake (ADFI) values (p<0.05). HA supplementation in pig feed had beneficial effects in lipid profiles without altering feed efficiency rate (FER). HA and BLP co-supplementation in pig feed decreased pH in longissimus thoracis (p<0.05). In addition, sensory characteristics were enhanced when pig feed was supplemented with HA and BLP without causing adverse effects in meat quality. Taken together, addition of HA and BLP in pig feed may produce functional meat products.
