Porcelain jacket crown and metal ceramic crown are representative esthetic restorations for full veneer crowns. Genarally, Porcelain jacket crown is more esthetic and closer to natural tooth appearance. However it is brittle and subject especially to tensile stress. Recently, a new reinforced porcelain for substructure, In-Ceram(VITA Zahnfabrik, Germany) was developed. This new reinforced porcelain is stronger than all other existing porcelain material and, can be widely used as one of the substructure materials. This study compared the deformation of In-Ceram and metal substructures for the stress of 5, 7 9, 11, 13, 15kg forced to the each lingual slope with 30 degree angle. Metal substructure was casted with 3 kinds of metals precious(Degudent H, Degussa, Germany), semiprecious(Degupal U, Degussa, Germany), nonprecious(Rexillum IQ, Rexillium, U.S.A.). Real time holographic interferometry was used for analysing the stress of these samples. This holographic interferometric analysis can evaluate the whole aspect of deformation without any morphological limitations and analyze finite deformation of samples by um and can be used on the idential samples not on computer model nor any other simulations. The results obtained were as follows 1. When the load by Max. 15kg was added to the lingual slope of each samples, in all cases of In-Ceram, Degudent H, Degupal U, Rexillium III substructures, tensile deformation on the labial aspect and compressive deformation on the lingual aspect were increaced from the cervical to incisal region. 2. When the surface deformation of each substructure was compared , In-Ceram showed uniform stress distribution without any flexion of its surface. In the metal substructures, Rexillium III on the labial aspect, Degupal U on the lingual aspect showed uniform surface deformation without any flexion. 3. In the case of Degudent H, severe changes of fringe patterns appeared at the incisal resion of labial aspect & whole lingual aspect, therfore interpretation of interferogram was not possible in this study: 4. When compared the Max. deformation of labial surfaces, In-Ceram showed least deformation in the load of 5,7,9kg and also in the load of 11,13,15kg except Rexillium M. When compared the Max. deformation of lingual surfaces, In-Ceram showed greatest deformation in all loading condition. 5. In the respect of stress distribution, In-Ceram was not disadvantageous. Holographic interferometry has a few methodological limit for the small dental restoration anlysis relatively great dynamic force condition. But as noncontact and nondestructive stress analyzing method, it is valuable to analyze 'finite deformation and more studies needed to apply it.

An empirical review on silk fabrics of the Chosun period showed that they varied in kind and design according to their uses. Thus the purpose of this study is to classify the fabrics into excavated and temple fabrics according to their uses and collected places and then to examine characteristics of each type. Excavated fabrics were most accounted for by tabby fabric, followed by satin, twill, leno and gauze and union cloth. Tabby fabric was most used throughout the Chosun period, followed by satin. This is supported by many literary records. Concerning excavated dresses of the same period, tabby fabric, especially Ju(紬) was the main material, followed by satin. Leno and gauze fabric was much less used than in the Koryo period. Among excavated dresses surveyed in this study, none was made of compound woven fabrics such as Brocade. Other excavation reports said that Brocade had been used for a cuff of coat in few cases, if any. Tabby fabric was widely used for both the right side and lining while twill and satin fabrics were mainly adapted to weave the right side because they had luster higher than the former, smooth sense of touching and unique designs.

장주현,노희영 강원대학교 정보통신연구소 2008 정보통신논문지 Vol.12 No.-

Recently, many software-programs are being plagiarized. Therefore a study on the prevention against plagiarism needs in aspect of information protection. Generally there are two methods to find out the plagiarism. The one lies in comparison with tokens of the source programs, and the other depends on structural similarity that analyzes the programs into control structures. This paper attempted to proof of objective reliability of the PDP method that measures the structural similarity of plagiarism in object-oriented program. Hence this paper presented the NCT method that improves the reliability through direct participation in decision for the structural similarity of program, and attested to the reliability of PDP method in comparison with similarity of two methods

The effect of alloying elements addition, austenite content and distributions on the tensile properties and corrosion resistance of duplex and super duplex stainless steels has been investigated by changing heat treatment conditions. With the addition of N and Cu, the austenite content of duplex stainless steels increased. After heat treating the super duplex stainless steel, the austenite content increased above 1200℃ and the ferrite single phase temperature shifted to 50℃ high in comparison to duplex stainless steel. Due to the stored energy induced from cold rolling the super duplex stainless steel. the specimen with fibous structure showed to be increased in austenite content compared to the specimen with dispersed structure. Tensile strengths decreased and elongations increased with increasing austenite content. The super duplex stainless steel with fibrous structure showed superior tensile strengths and elongations to the fibrous duplex stainless steel and super duplex stainless steel with dispered structure. The effect of Cu and CU+W addition on tensile properties was small. The passive current density and critical current density of high alloyed super duplex stainless steel showed value in comparison to duplex stainless steel. The Cu+W added super duplex stainless steel appeared the highest corrosion resistance among all specimens.

The clouds-shaped pattern is originated from Taoism, Buddhism, and Confucianism. It stands for good-luck, longevity and productivity. It has been used on its own or with other patterns since the ancient times. It also has various forms. It particularly was used more frequently than any other patterns as a typical good-luck pattern, representing auspiciousness, divine authority, and so on in Chosun dynasty. The pattern, according to its component parts, is classified as individual type and compound type, which is mixed with other patterns such as treasure pattern, plant pattern, letter pat-tern, or animal pattern. For both individual type and compound type, swastika-shaped cloud pattern was mostly used. For compound type, the pattern compounded of treasure pattern was extraordinarily used a lot. In terms of the arrangement, the most common arrangement methods were brick-shaped arrangement and dense type arrangement, the arrangement method that spreads the patterns all over the surface. Among the fabrics with clouds-shaped pattern, satin damask fabrics had the majority. Clouds-shaped pattern was used a lot in men's Po(coat), such as Dahnryoung, Jiknyoung, Chollik, etc. rather than in women's clothes. It was a typical pattern used in Dahnryoung, an official uniform that represented people in the highest class in Chosun dynasty. The divine power symbol of this pattern indicated the authority and dignity that the upper class people could have.
