The purpose of this study was to examine the Korean red carpet fashion of Daejong, Bluedragon, Korean Film Awards from 2002 to 2004, focusing on nominates of female movie stars and presidents. Leading colors were black and white but pale and vivid colors were also chosen. Dresses were made of satin, chiffon, lace and velvet mainly, and patterned fabrics made strong statements among them. Based on the long and slim silhouette, there were lots of details using beads, sequins and crystal stones for manipulating lighting effects. Fur shawls along with diamond jewelry were favorite items of many stars. They preferred dresses of international brands to that of domestic brands. Esthetic qualities of red carpet fashion were categorized as decorative gorgeousness, sophisticated elegance, glamourous sensuality, paradoxical presentation, pure innocence, and Korean refinement.

Since the late 1930s, acrylic resins have been the materials of choice for the fabrication of complete denture bases. It has excellent esthetic properties, adequate strength, low water sorption, and low solubility. But acrylic resin has disadvantage of processing shrinkage that reduces denture retention and accuracy of denture occlusion. Metals also have been used in denture base material. Metals used in denture bases display excellent strength and dimensional stability. The major disadvantages associated with metal denture bases include increased cost, difficulty in fabrication, compromised esthetic qualities, and inability to re-base. The purpose of this study is to compare the artificial tooth movements of complete dentures with resin bases and metal bases after curing, deflasking, polishing immersion in water for 1 week and 4 weeks. Twenty-four maxillary complete resin denture bases with artificial teeth were fabricated. Twelve of them were resin based and other twelve of them were metal based. Fine crosses were marked on the incisal edges of right central incisors and distobuccal cusps of be second molars. Measurements were done for the changes of distances of reference points at the time of wax denture, after deflasking after decasting after polishing after immersion in water for 1 week and 4 weeks Meaurements were done to the accuracy of 0.001mm with a measuring microscope. The results were as follows : 1. Metal base showed significantly less tooth movement than resin base after curing and decasting (p<0.01). 2. Metal base showed significantly less tooth movement than resin base after polishing (p<0.01). 3. After immersion in water for 1 week and 4 weeks, metal base showed less movement than resin base. Difference was significant for anterior-posterior distances (p<0.01), but not significant for molar-to-molar distance (p>0.01). 4. 1 week and 4 weeks of immersion failed to compensate the initial processing shrinkage of metal and resin bases (p>0.01).

When we design a dress, we should not only consider the esthetic sense and the relationship between movements of the body and the type of dress, but also the combination between the qualities and proper uses of textiles. recently the sale of ready-made clothes has been booming but I wonder whether they have been made in accordance with research concerning body movements and dresses. I would like to make the following observations on dresses, because I have personally suffered the inconvenience of restricted arm movements when wearing ready-made clothes. I have made four types types of foundations with muslin and Jersey, with these foundations I measured the degree of tension or how much the waist-line was drawn up then the arm was moved in increments of 45 degree angles and there by covering the entire span of vertical and horizontal movements. I have intended to experiment with sleeves of differing height in several ways. Concerning the movement factor, I have determined that with excessive activity vertical movements are twice as uncomfortable as horizontal movements. Concerning the faburic, I have found that because jersey has more elastic qualities than muslin, it has proven to be more responsive to body movements. concerning dresses, I have fund that the higher the height of the sleeves, the more uncomfortable it is to move the arms and the greater the degree to which the waist-line is drawn up. As a result this experiment I have made the following observations. Firstly, the vertical movement of the arms to a 180 degree angle has the most extreme influence on the breadth of movement of the waist-line. Secondly, because jersey permits freer body movements than muslin, it should be the preferred material for use in making sportswear. Thirdly, the formula A·H/4+3 of the sleev's cap height is suitable for making street dresses and formal wear. The formula A·H/5 and A·H/6 are properly used when making working clothes and sportswear, and the formula A·H/8 is proper for a sleeping garment and clothes for patients. Fourthly when deciding to any garments, it is important to consider the amount of arm movement anticipated and the relationship between the material and the degree to which the waistline is drawn up. In nder-blouse, when we raise our arms to the most extreme position, we should at that point still have 20∼25 cm of material remaining under the waist-line which includes the maximum of 14.1cm plus part of the blouse and breath of skirt's belt. In the case of the over blouse it is proper for us to have the length of 17∼20 cm remaining below the waist-line.

The composite resin, due to its esthetic qualities, is considered the material of choice for restoration of anterior teeth. With respect to shade control, the direct-placement resin composites offer some distinct advantages over indirect restorative procedures. Visible-light-cured (VLC) composites allow dentists to match existing tooth shades or to create new shades and to evaluate them immediately at the time of restoration placement. Optimal intraoral color control can be achieved if optical changes occurring during application are minimized. An ideal VLC composite, then, would be one which is optically stable throughout the polymerization process. The shade guides of the resin composites are generally made of plastic, rather than the actual composite material, and do not accurately depict the true shade, translucency, or opacity of the resin composite after polymerization. So the numerous problems associated with these shade guides lead to varied and sometimes unpredictable results. The aim of this study was to assess the color changes of current resin composite restorative materials which occur as a result of the polymerization process and to compare the color differences between the shade guides provided with the products and the actual resin composites before- and after-polymerization. The results obtained from this investigation should provide the clinician with information which may aid in improved color match of esthetic restoration. Five light activated, resin-based materials (${\AE}$litefil, Amelogen Universal, Spectrum TPH VeridonFil-Photo, and Z100) and shade guides were used in this study. Three specimens of each material and shade combination were made. Each material was condensed inside a 1.5mm thick metal mold with 10mm diameter and pressed between glass plates. Each material was measured immediately before polymerization, and polymerized with Curing Light XL 3000 (3M Dental products, USA) visible light-activation unit for 60 seconds at each side. The specimens were then polished sequentially on wet sandpaper. Shade guides were ground with polishing stones and rubber points (Shofu) to a thickness of approximately 1.5mm. Color characteristics were performed with a spectrophotometer (CM-3500d, Minolta Co., LTD). A computer-controlled spectrophotometer was used to determine CIELAB coordinates ($L^*$, $a^*$ and $b^*$) of each specimen and shade guide. The CIELAB measurements made it possible to evaluate the amount of the color difference values (${\Delta}E{^*}ab$) of resin composites before the polymerization process and shade guides using the post-polishing color of the composite as a control, CIE standard D65 was used as the light source. The results were as follows. 1. Each of the resin composites evaluated showed significant color changes during light-curing process. All the resin composites evaluated except all the tested shades of 2100 showed unacceptable level of color changes (${\Delta}E{^*}ab$ greater than 3.3) between pre-polymerization and post-polishing state. 2. Color differences between most of the resin composites tested and their corresponding shade guides were acceptable but those between C2 shade of ${\AE}$litefil and IE shade of Amelogen Universal and their respective shade guides exceeded what is acceptable. 3. Comparison of the mean ${\Delta}E{^*}ab$ values of materials revealed that Z100 showed the least overall color change between pre-polymerization and post-polishing state followed by ${\AE}$litefil, VeridonFil-Photo, Spectrum TPH, and Amelogen Universal in the order of increasing change and Amelogen Universal. Spectrum TPH, 2100, VeridonFil-Photo and ${\AE}$litefil for the color differences between actual resin and shade guide. 4. In the clinical environment, the shade guide is the better choice than the shade of the actual resin before polymerization when matching colors. But, it is recommended that custom shade guides be made from resin material itself for better color matching.
