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.

This study was conducted to investigate the physicochemical characteristics of Sunchang traditional kochujang(fermented hot pepper-soy bean paste) for quality standardization. The kochujang samples, which have been fermented for 8 months in 1999, were collected from 20 firms at folk village in Sunchang area and analyzed their chemical compositions and color reference. The mean value of moisture, amino-type nitrogen, pH, acidity and salt content of the samples collected were $44.62{\pm}1.79%$, $132.66{\pm}21.67\;mg%$, $4.52{\pm}0.08$, $15.77{\pm}1.62$ and $8.76{\pm}1.55%$, respectively. The moisture, pH, acidity and salt content of each sample did not show much differences among samples. The Hunter values(L, a and b) of Sunchang traditional kochujang were $25.72{\pm}1.58$, $23.26{\pm}1.71$ and $9.86{\pm}0.94$, respectively. The mean content of amino-type nitrogen of Sunchang traditional kochujang was $132.66{\pm}21.67\;mg%$, and there were a little difference between the minimum(100.33 mg%) and the maximum(164.56 mg%). The main free sugars of Sunchang traditional kochujang were fructose($1.86{\pm}1.01%$), dextrose($4.29{\pm}2.06%$), sucrose($0.54{\pm}1.21%$), and maltose($1.48{\pm}0.77%$). The contents of fructose, dextrose, and maltose had little difference among samples. The fatty acids in Sunchang traditional kochujang were composed of palmitic, stearic, oleic, linoleic, linolenic, octadecatetraenoic, arachidonic and behenic acid. The linoleic acid(18:2) showed the highest, occuping 59.37% of the total fatty acids.

The purpose of the study was to find out design problems of grand chapel of the Protestant church and to set analysis frame based on theoretical study on abstract symbolism and investigate cases and to give reference of abstract symbolism expression of design of the chapel. The findings were as follow: Introduction of the light was found to be the most outstanding among abstract symbolic factors, and metaphor was commonly used to express abstract symbols. First, 1) Introduction of the light was found to be the most outstanding at application of abstract symbolic factor of modern Protestant church to be the highest among pastors, office bearers, believers and non-Christians. 2) The metaphor was found to be the most noticeable among abstract symbolic expressions. Second, the findings of questionnaire survey was: The findings of questionnaire of not only abstract symbolic expression factor but also symbolic expression method was not to cognize ideas of pastor, office bearers, believers and designers often. This was because abstract symbolism was made from point of view of designers. Therefore, abstract symbolic expression factors of grand chapel of modern Protestant church, for instance, effective introduction of the light, light quoting the Bible sayings, material, color and shapes, etc should be used with metaphor and symmetry to give Christians value of symbol and to hide meaning of symbolic values to non-Christians who do not know contents of the Bible.

In this paper, A new stereo matching method based on reliability space is proposed to acquire 3D information from 2D image. In conventional stereo matching methods, speed is sacrificed to achieve high accuracy. To increase the matching speed while maintaining a high accuracy, this paper proposes this stereo matching method. It first makes the disparity space image for comparing all of the pixels on the stereo images. Then it produce reliability space through analyzing this value. and, By comparing the reliability space according to disparity, it makes disparity map. Moreover, the parts that make regional boundary errors are corrected by classifying the boundary of each region with the reference to color edge. The performance of the proposed stereo matching method is verified by various experiments. As a result, calculation cost is reduced by 30.6%, while the image quality of proposed method has similar performance with the existing method.

This study carefully explored today's preferable beauty images, analyzed Korean adult purchasing trends of functional underwear and market analysis of the most popular items and their designs. Information and methods are based largely on reference book material as well as analysis of real domestic data. The paper's research timeline simply spans the last three years, as in accordance with project parameters. Helping improve body shape, foundation literally means 'substructur' and 'base'. The formativeness in these adult foundations typically has three main category classifications. First, natural modern image. This is where we find natural beauty including that which embodies a cool modern sense. Here, you can often see such patterns as either stripes and dots, or simply no patterns at all. Colors are green, red-brown, incarnadine, or khaki from a natural or basic human body color. Its products are marketed as both solid and durable eco-friendly materials, and lace-seethrough. Fashion's natural modern image is undoubtedly the most popular style purchase choice among both genders. Second, sweet romantic image. This mainly consists of two concepts : a sweet and romantic theme, and visual appeal. Patterns include flowers, lips, heart, stars, candies and various other appealing characters. Its main colors are pink, yellow, red, purple, and violet. Products are decorated with laces, frills and ribbons. Since only men's semi-girdles carry such designs, this fashion foundation is largely a women's world. While men show an obvious interest in foundation, they still mostly prefer the choice of natural modern images. Third, mystic sexy image. This is defined as all feminine images of mysterious and classic sexual beauty. Patterns are variously expressed as paisley, flowers, and geometric. Colors are largely purple, blue-green, royal-blue, cobalt, and black. Products are commonly decorated with beading, spangles, hot-fixes and so on. While this image can be found in all kinds of women's foundations, it typically appears only in men's corsets and girdles.

The purpose of this study is to analyse the occurrence and evolution of Mao suit which is important position in the modern costume history of China and to provide a source of design inspiration to contemporary fashion designers. In the research method, literature review and case studies was conducted in parallel. For the literature review, changes of Mao suit in each age were reviewed with reference to the related documents, Chinese costume and cultural history, prior research papers and internet resources. The case analysis was qualitatively done focusing on the silhouette, color and detail of clothes in fashion collections. The scope of the study was from 1912 to 2000. The case analysis of the Mao suit applied to the contemporary fashion was made on the applications centered around 'London Collection', 'New York Collection', 'Paris Collection', 'Milan Collection' and 'Chinese Fashion Week' from 2008 to 2015. The results found that Mao suit changed into many different forms after Sun Wen designed it for the first time in 1912. This study classified it into Phase 1(1912~1927), Phase 2(1928~1965), Phase 3(1966~1977), and Phase 4(1978~2000) with historical and political issues and conformational changes in Mao suit. The frequency analysis of the cases of the fashion collections using Mao suit from 2008 to 2015 showed an increased application of Mao suit to the western collection in New York, Paris and London in 2008 due to the impact of Beijing Olympics. However, from 2009 onwards, the frequency of the utilization of Mao suit was higher in the Chinese Fashion Week and the New York Collection. This cause is explained by the fact that the designers who inspired from Mao suit in the New York Collection are American Chinese.

COMS accommodates multiple payloads; Meteorological Image(MI), Ocean Color Imager(GOCI) and Ka-band communication payloads. In order to improve the quality of MI visible channel, the moon image has been taken into account as backup reference in addition to Albedo monitoring. However, obtaining the moon image by adding special mission schedule is not recommended after IOT, because we may miss chances to obtain meteorological images during the time slots for special imaging. As an alternative solution, an approach extracting moon image from MI FD(Full Disk) image has been proposed when the moon is positioned near to the earth. However, prediction of acquisition time of moon image is somewhat difficult as the moon moves while the MI is scanning type sensor. And the moon can not be seen when it is behind the earth or outside of FD field of view. This paper discusses how effectively the moon can be detected by the MI FD imaging. For that purpose, this paper describes an approach taken to predict the time when the moon image is achievable and then introduces the results obtained from computer simulation.

This study aims to analyze the expressive aspect of men's shirts through examining the characteristics of men's shirts with the trend of men's clothing well represented and considering the image based on high fashion. As a method of study, I have conducted the theoretical study through the literature data, and the content analysis through photographs from S/S collection in 2005 to F/W collection in 2010. Especially, in the recent men's shirts, the materials of glossy silk, wavering chiffon and jersey tend to appear and various images are represented with the tasteful decoration such as ruffle, pin tuck and embroidery together with pastel color. Thus, the result of this study is as follows: Firstly, the masculine and romantic images are researched as the image emphasizing the beautiful and soft masculine beauty which doesn't lose the masculinity even though they are seasonedwith the feminine elements. Soft masculine beauty is emphasized by using romantic image decoration of frills, beads and pin tuck or silk, jersey and openwork materials etc. Secondly, practical fusion images have been studied as the images emphasizing the freshness with practicality through grafting more than two items onto one shirt. Many designs have appeared representing new shapes by grafting more than two items onto one shirt or obscuring the border line between the items. Thirdly, the avant-garde chic images have been researched as the image emphasizing the chick image through representing unique and odd designs by excessively expressing the silhouette in general shapes of shirts. I come. to find that the mainly the designs, emphasizing the uniqueness and the distinction with transformed shapes of sleeves, cuffs and the length of shirts in exaggerated manners, are appearing. Thus, I intend to provide a reference material which will be useful for the newly created design and researches of figurative characteristics in the future fashion.

In this paper, improved contour region coding method is proposed to accomplish better depth map coding performance. First of all, in order to use correlation between color video and depth map, a structure in SVC is applied to 3DVC. This can reduce bit-rate of the depth map while supporting the video to be transferred via various collection of network. As the depth map is mainly used to synthesize videos from different views, corrupted contour region can damage the overall quality of video. We hereby adapt a new differential quantization method when separating the contour region. The experimental results show that the proposed method can improve video quality by 0.06~0.5dB which translate the bit rate saving by 0.1~1.15%, when compared to the reference software.
