  • Statement of problem: All-ceramic restorations have been advocated for superior esthetics. Various post and core systems have been used to improve the strength of damaged teeth, but it is unclear whether they affect the final shade of finished all-ceramic restorations. Purpose: The influence of different types of post and core systems on light transmission through all-ceramic crowns was assessed by spectrophotometric analysis. Also the masking effect of different thickness of ceramic ingot was evaluated. Material and Methods : Forty-five sample disks (15mm in diameter) at several thickness(1.0, 1.5, 2.0mm) and value(shade 100, 200, 300) were made in heat pressed ceramic(IPS-Empress). Background specimens simulating gold-alloy cast posts(Type III casting gold alloy), metal posts(Ni-Cr casting alloy) and ceramic posts(CosmoPost) were fabrica-ted. Resin composite(Z250, A3 shade) was used as a tooth substrate reference. For each combination, the change in color was measured with a spectrophotometer. Readings were performed for 2 conditions (1) ability of ceramic to mask the core in relation to its thickness(1.0, 1.5, or 2.0mm) ; (2) influence of post and core types on the final color of the ceramic. Data were recorded according to the CIE $L^*a^*b^*$ systems and color difference($\Delta$E) was calculated. Results: 100 shade ingot: when ceramic thickness was 1.0mm, $\Delta$E value for ceramic post larger than 1 but $\Delta$E value for metal and gold post was larger than 2. For ceramic thickness of 1.5mm, only $\Delta$E value for metal was larger than 2, and the other samples' $\Delta$E value was smaller than 2. For ceramic thickness of 2.0mm, $\Delta$E values for all specimens was smaller than 2. 200 shade ingot: when ceramic thickness was 1.0mm, $\Delta$E value for ceramic post was smaller than 1 but $\Delta$E value for metal and gold post was larger than 2. For ceramic thickness of 1.5 mm, only the $\Delta$E value for metal was larger than 2, and the other samples' $\Delta$E value was smaller than 2. For ceramic thickness of 2.0mm, $\Delta$E values for all specimens was smaller than 1. 300 shade ingot: when ceramic thickness was 1.0mm, only $\Delta$E value for metal was larger than 2 and the other samples' $\Delta$E value was smaller than 2. For ceramic thickness of 1.5mm, $\Delta$E values for all specimens was smaller than 1. For ceramic thickness of 2.0mm, $\Delta$E values for all specimens was smaller than 1. Conclusion: The final esthetic result of the IPS-Empress glass-ceramic restoration was not affected by the presence of different core materials when the thickness was more than 2.0 mm. When ceramic thickness decreases to 1.5mm, it is advised to take the substrate aspects into consideration. If the ceramic thickness is less than 1.0mm, using the tooth color matched substrate is strongly recommended.

  • The purpose of this study is to examine the interior textile color changes and trends by analyzing the characteristics of interior color hues and tones. Heimtextil in the interior field was selected for color trend analysis from 1996 to 2000. The conclusions of this study are as follows: First, In terms of hue, warm colors like Y, YR, and R were most prominent in all four years. Some new colors, however, emerged with higher frequency. The frequency of GY and B increased in 96/97, GY, BG and PB in 97/98 PB and B in 98/99, and B and PB in 99/2000. Especially between 96/2000, the frequency of PB and B has been increased, although the frequency of GY has been decreased. Over the four years, P, RP, and Neutral showed medium frequency, and G and BG showed low frequency. Gold appeared as an accent color in two years while silver appeared in one year. In summary, warm colors like Y, YR, and R were most prominent in interior color. Second, In terms of tone, p, b, v, and sf were most prominent over the four years. Although 에 and ltg appeared with high frequency n general, a wide variation was presented. The tones such as p, dp, and v appeared with high frequency in the three years of 96/97, 97/98 b and sf in 97/98 ; lt, dk and sf in 98/99. On the other hand, a new trend emerged in 99/2000. In this year, ltg, sf, s, d and dkg appeared with high frequency unlike the other three years. In other words, soft or light tones, such as pale, soft, light, grayish, and deep, and strong tones, such as vivid and bright, appeared with high frequency.

  • Studying the dress style of the Buddhist Goddess of Mercy SU WOL KWAN EUM DO (Drawings on the Buddhist Goddess of Mercy who is watching the Moon reflected in the still water), it is composed of a splendid, jewel crown with five colors, a light and flimsy, non-colored veil with many kinds of gold·plated patterns. This gold·plated carapace figures on a scarlet ground are drawn on the veil and the oval-type flower figures mixed with a scarlet lotus blossom ard arranged. An arabesque pattern of BOSANGHWA (an imaginary, Buddhistic flower figure) is mainly used for both line decorations and necklace. Like this, various kinds and types of figures are in harmony in spite of many changes in figure design. The SU WOL KWAN EUM DO in Koryo dynasty is full of colorful, subtle, harmonious figures which are unique style, which cannot be found in japan, China, and so on. In other words, most of most of dress patterns which are shown in SU WOL KWAN EUM DO are China ink paintings with mountains and waters as its setting. In case of color painting, figure designs are seldom used. The dress pattern in SU WOL KWAN EUM DO of koryo dynasty is characteristic of its variety and magnificent colors.

  • A simple, highly sensitive and selective method based on the rhodamine B-covered gold nanoparticle with dual-readout (colorimetric and fluorometric) detection for $\small{L}$-cysteine is proposed. A mechanism is that citrate-stabilized AuNPs were modified with RB by electrostatic interaction, which enables the nanometal surface energy transfer (NSET) from the RB to the AuNPs, quenching the fluorescence. In the presence of $\small{L}$-cysteine, it was used as a competitor in the NSET by the strongly Au-S bonding to release RB from the Au surface and recover the fluorescence, and the red-to-purple color change quickly, which was monitored simply by the naked eye. Under the optimum conditions, the detection limit is as low as 10 nM. The method possessed the advantages of simplicity, rapidity and sensitivity at the same time. The method was also successfully applied to the determination of $\small{L}$-cysteine in human urine samples, and the results were satisfying.
