The purpose of this study was to compare the fracture and shear bonding strength of resin-modified glass ionomer cements with composite resin and conventional glass ionomer cement Three kinds of restorative materials including a composite resin (Z 100), a conventional glass ionomer cement(Fuji II), and resin- modified glass ionomer cements(Fuji II LC, Vitremer, Dyract and Compoglass) were investigated in this study. For measurement of fracture and shear bonding strength, disk samples of the materials were prepared and cylindrical samples of the materials were bonded the flat enamel and dentin surfaces according to manufactuer's instructions. All specimen were determinated by using an Instron testing machine with a crosshead speed of 1 mm/min. Then, each treated enamel and dentin surface was observed by SEM. The following results were obtained. 1. The bi-axial flexural strength of Z 100 was highest, and Fuji n LC, Vitremer, Dyract and Compoglass were significantly higher than Fuji n (P<0.05). 2. The shear bonding strength of Z 100 on the enamel and dentin surface was higher than other experimental groups except Fuji II LC(P<0.05). Fuji II LC was significantly higher than Fuji II (P<0.05), but in the case of Vitremer, Dyract and Compoglass were similar to Fuji II (P>0.05). 3. The shear bonding strength of Z 100 and Fuji II LC on the enamel surface were highly increased as compared with dentin surface (P<0.05), but in the case of Fuji II, Vitremer, Dyract and Compoglass were not different between enamel and dentin(P>0.05). 4. In the Z 100 and Fuji II LC, obvious etched enamel surface and exposed dentinal tubules according to remove of smear layer and smear plug were observed.

We have successfully commercialized a novel optical compensation film, OCB-WV film, for OCB-LCD-TVs which has fast response time and wide viewing angle. The OCB-WV film consists of a 45degree-aligned discotic layer and a high Rth biaxial TAC film, which is suited for a roll-to-roll polarizer manufacturing process. This OCB-WV has brought out the excellent features that OCB intrinsically has, making nextgeneration fast-response LCD-TVs possible and free from image blurring in conjunction with an impulsive driving scheme.

We have constructed the Mount Fuji submillimeter-wave telescope at Nishiyasugawara (alt. 3725 m) near the summit of Mt. Fuji (alt. 3774 m). Thanks to the excellent condition of Mt. Fuji, we have successfully carried out the [CI] survey toward more than 40 square degrees of sky, including qrion MC, Taurus MC, Rosetta MC, DR 15, DR 21, NGC 1333, NGC 2264, W 3, W 44, W 51, L 134, p-Oph. Our [CI] survey have revealed that the [CI] 492 GHz emission widely extends to the molecular clouds. The spatial and velocity structures of the [CI] 492 GHz emission resemble those of 13CO J=l-0 in many molecular clouds, implying that [CI] 492 GHz and $^{13}CO$ J=1-0 are emitted from the same gas. The column density of $C^o$ linearly correlates with that of CO up to high Av, suggesting that $C^o$ exist in the deep interior of molecular clouds. In several regions, we have found that the distributions of $C^o$ and CO are different from each other. The $C^o$-rich area is found in the Hieles' cloud 2. The C+/CO/$C^o$ configuration is found in DR 15, p-Oph, M 17, Orion KL, and NGC 1333. These results indicate that an origin of $C^o$ is unrelated with the photodissociation process. We discuss the observed $C^o$ distributions in relation to the non-equilibrium chemistry.

레진 강화형 글래스 아이오노머 시멘트의 접착 강도를 알아보고, 타액 오염이 접착제의 종류에 따라 접착 강도에 어떠한 영향을 미치는지 관찰하여 봄으로써 임상적 효용성을 알아보기 위하여 본 연구를 시행하였다. 교정 치료를 목적으로 발거된 소구치에 교정용 복합 레진 접착제로 Ortho-One, 레진 강화형 글래스 아이오노머 시멘트로는 Fuji Ortho LC, Vitremer, Advance를 사용하여 통상적인 과정의 브라켓 접착을 하였으며, 타액 오염군은 타액 오염후에 건조 한 뒤 브라켓을 접착한 후 증류수에 침적하고 $37^{\circ}C$ 항온조에 24시간 보관하였다. 만능시험기로 인장 접착 강도를 측정하여 다음과 같은 결과를 얻었다. 1. 통상의 방법으로 브라켓을 부착한 경우 인장 접착 강도는 Ortho-One군에서는 $7.68\pm1.76$ 이었으며, Advance군에 서는 $7.87\pm2.80$, Fuji Ortho LC군에서는 $4.99\pm2.53$, Vitremer군에서 는 $2.80\pm0.88$ MPa 나타났다. 타액 오염시킨 경우 인장 접착 강도는 Ortho-One군에서 는 $4.12\pm1.67$, Advance군에서는 $5.37\pm0.68$, Fuji Ortho LC군에서는 $4.41\pm1.61$, Vitremer군에서는 $2.60\pm1.10$ MPa 로 나타났다. 2. 타액 오염시킨 경우 Fuji Ortho LC와 Vitremer는 거의 영향이 없었고 (p>0.05), Ortho-One과 Advance는 큰 폭의 접착 강도 저하 현상을 나타냈다 (p<0.05). 3. Advance와 Ortho-One, Fuji Ortho LC는 만족할 만한 인장 접착 강도를 나타내어 브라켓 접착시 임상적 유용성이 있으리라 생각된다.

The volatile components in 'Fuji' apple were effectively determined by a headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS). A total of 48 volatile components were identified and tentatively characterized based on National Institute of Standards and Technology (NIST) MS spectra library and the Kovats GC retention index I (RI). The harvested Fuji apples were divided into two groups: 1-methylcyclopropene (1-MCP) treated and non-treated (control) samples for finding important indicators between two groups. The major volatile components of both apples were 2-methylbutyl acetate, hexyl acetate, butyl 2-methylbutanoate, hexyl butanoate, hexyl 2-methylbutanoate, hexyl hexanoate and farnesene. No significant differences of these major compounds between 1-MCP treated and non-treated apples were observed during 1 month storage. Interestingly, the amount of off-flavors, including 1-butanol and butyl butanoate, in 1-MCP treated apples decreased over 5 months, and then increased after 7 months. However, non-treated apples did not show significant changes for off-flavors during 7 month storage (p<0.05). The non-treated apples also contained the higher levels of two off-flavors than 1-MCP treated apples. These two compounds, 1-butanol and butyl butanoate, can be used as quality indicators for the quality evaluation of Fuji apple.

Effects of chitosan coating on respiration rate and internal gas composition of 'Fuji' apple and 'Satsuma' mandarin were investigated and compared to wax emulsions and two commercial coating materials. Chitosan coating reduced respiration rate significantly (p<0.05) in 'Fuji' apple and 'Satsuma' mandarin compared to uncoated and other coating materials. Chitosan coating on 'Fuji' apple showed the highest $CO_2$ and the lowest $O_2$ concentration in the internal gas composition at $5^{\circ}C$ but showed no differences compared to other coating materials at $20^{\circ}C$. 'Satsuma' mandarin showed significantly high $CO_2$ concentration in chitosan coating at $20^{\circ}C$ but there were not significant differences among coating materials in $CO_2$ and $O_2$ composition at $5^{\circ}C$.
