[์˜๋ฌธ]I. Introduction : The long-term prognosis of a composite-restored tooth is mainly affected by the sealing efficacy of the restorative material on the dental structures. Therefore the โ€˜leakage testโ€™ is the essential factor to test. The purpose of this study is to search for the nondestructive methods to observe dentin-composite interfaces using a AgNO3 solution and micro-CT II. Material and Methods : In this study, about 50 human premolars and a AgNO3 solution have been used. 1mm thickness specimen, crown-shaped specimen, tooth-shaped specimen was prepared. Each specimen was infiltrated by a AgNO3 solution in various conditions - including โ€˜Gapโ€™, โ€˜Spaceโ€™, NaOCl, EDTA, etching, pressure, minus pressure, bonding - and observed by micro-CT. III. Results : First, the AgNO3 solution was infiltrated by dentinal tubules by capillary action. Second, combination of the NaOCl solution and EDTA solution increased the ability of an AgNO3 infiltration. Third, external pressure increased the ability of an AgNO3 infiltration. Fourth, 1mm thickness specimen with NaOCl, EDTA and external pressure showed successful result of AgNO3 infiltration model. Fifth, there was no successful infiltration model in tooth-shaped specimen. IV. Conclusions : In this research, results showed that the AgNO3 solution can infiltrate dentinal tubules. Therefore, using an AgNO3 solution and micro-CT is possible to observe the dentin-composite interfaces as a nondestructive method under sufficient pressure and combined irrigation of NaOCl and EDTA. The 1mm thickness specimen could be a experience model for further research.ope

This study is a longitudinal research to investigate the change of psychological awareness and mental characteristics in native Yabian Koreans in China. The difference between first survey data(1991) and second survey data(2000) was analyzed. Another purpose of this study was to find the differences of psychological awareness in Korean generation groups at Yanbian territory, China. The data from native Yanbian Korean groups(n=558) were accordingly analyzed. The survey questionnaire was composed of items reflecting the individual subject's view of values and psychological items concerning evaluation of incumbent social issues. The major result of this study was an increased tendency toward capitalistic values and preference of psychological well-being In Yanbian Koreans. In addition, Yanbian Koreans in the year of 2000 took relatively pessimistic view of the unification of Korea as compared to those in 1991. The implication and limitation of this research result were discussed
