The purpose of this study was to investigate the effects of desensitizer on shear bond strength of adhesive resin cements for all ceramic crown. For this study, Gluma $desensitizer^{(R)}$(Heraeus Kulzer, Germany) and MS $Coat^{(R)}$(Sun medical, Japan) were used as desensitizer, and Bistite $II^{(R)}$ resin cement(Tokuyama, Japan) and Variolink $II^{(R)}$ resin cement (Ivoclar, Liechtenstein) were used. IPS Empress ceramics were bonded to dentin surfaces after application of desensitizer and shear bond strength of specimens were measured using UTM(Zwick 1456 41. Zwick, Germany) at a crosshead speed of 1mm/min. The obtained results were as follows : 1. The shear bond strength of both resin cements were not affected by Gluma $desensitizer^{(R)}$ containing HEMA 2. The shear bond strength of Bistite $II^{(R)}$ resin cement was significantly decreased by MS $Coat^{(R)}$. 3. The failure mode in MS $Coat^{(R)}-Bistite \;II^{(R)}$ group was mainly adhesive type between dentin and resin cement. but that of Gluma $desensitizer^{(R)}$-Variolink $II^{(R)}$ group was mainly mixed type, combined adhesive failures between dentin and resin cement or porcelain and resin cement.

현대 사회는 복잡하고 다원화되어 좀처럼 합리적 의사결정을 내리기 어렵다. 그 원인의 근본은 체계와 생활 세계의 지나친 분화에 의하여 야기 된 것이기 때문에 체계와 생활 세계의 통합을 통하여 해결할 수밖에 없다. 그것은 사회과학의 지식만으로 획득되는 것도 아니고 일반적인 토론학습에 의해서도 쉽게 달성될 수 없는 문제이다. 일반적 토론학습은 대부분 대화 참여자가 전략적 동기에 의하여 대화를 진행시키기 때문에 의사소통이 왜곡 될 우려가 남아 있고 결국은 전략적 합의는 언제든지 폐기 될 위험성이 내포되어 있다. 그리고 체계기능의 입장에서는 체계의 효율성은 생활세계의 삶을 위협한다. 하버마스는 이러한 위험이나 위협으로부터 탈출할 수 있는 방법을 대화행위자들이 선험화용론의 입장에서 “담론 규칙”을 따르고 순수한 합의에 이를 경우에만 가능하다고 주장한다. 본고에서는 합리적 의사소통인 순수한 합의는 대화행위자들이 합리적 대화의 조건인 보편타당한 구성요소를 대화 속에 포함시키면서 상대방과 합리적으로 소통할 수 있는 능력을 가질 때 가능하다는 것을 통합적으로 규명한 후에 이 논리를 실제 수업에 어떻게 적용할 것인지 개론적 측면에서 접근하였다. This essay is to answer “What is rationality of human communication? and ‘Why we must answer this question? Democratic societies generally cultivate a disputatuos public sphere in which citizens are encouraged to “have their say” on any issue arises. In nondemocratic societies, many people have a principled opposition to these sorts of disordered public debates, and seek to rely upon other institutional structures to resolve public policy. This suggest that, even if every society shares the same general practice of argumentation and “rules of discourse” they may choose not to use this practice to resolve all of their problems. These problems ought to be resolved in the status of a rationality. As possible response to this challenge we would transform the methodological principle of self matching of reconstruction of rationality. These are first, means end rationality, second, communicative consensual rationality, third, functional structural system rationality. In the light of these competing approaches to our problem, I would like to draw a discourse to be both a transcendental function and a type of communication. From this point: I wish to propose the following thesis: in asking question of the rationality of human communication, one has first to ask about the rationality of a discursive argumentation concerning the question. This question concerns the rationality that is presupposed by a rational theory communication. Against this suggestion, it may be objected that our conception of arguing as form of communication should rather lead to an attempt at accounting for the rationality of communicative action and thus an immediate discussion of competing claims of current theories of communicative action. In arguing we cannot give up raising claims to universal truth to be valid for, and hence acceptable by everyone, i.e. for every possible member of the indefinite “system” of an ideal communication community. So in any event, we cannot deny that in arguing about the problem of rationality we must suppose a rational procedure of discourse that is different from strategic rationality, a procedure through which we may come to grounded consensus about meaning claims and truth claims. Thus the way to reach self matching reconstruction of the rationality of communication is the transcendental pragmatic argumentation.

The objectives of this study are to confirm that Worincheongangjigok consists of a total of 583 songs, and to reconstruct the last songs (No. 582?583) of Worincheongangjigok along with the restoration of the damaged last part of Worinseokbo v.25. The last part of Worinseokbo v.25 contains song No. 583 of Worincheongangjigok along with gloss, but because the part was damaged severely it is controversial whether No. 583 is the last song of Worincheongangjigok. Thus, Chapter Ⅱ of this paper revised and supplemented existing evidences that Worincheongangjigok No. 583 in Worinseokbo is the last song, and presented new bibliographic evidences. The new evidences are the presumption that the number of missing pages at the end of the volume may not be much different from the number of missing pages at the beginning of the volume and the fact that the gloss in the last part of the volume has a different number of letters per line from that in the glosses for the part of Worincheongangjigok and for the part of Seokbosangjeol. In this study, the reconstruction of the missing part of Worincheongangjigok No. 582 and 583 was based on the reconstructed contents of the last gloss in Worinseokbo v.25. As a result, it was found that narratives No. 1 and 2 of Worincheongangjigok are symmetrical to the last songs No. 583 and 582, but it was impossible at this point to reconstruct the last phrase of No. 583 of Worincheongangjigok. I expect further discussion on this phrase in future literary studies.

This study was undertaken to determine if Salviae Radix (SR) exerts protective effect against oxidant-induced inhibition of phosphate uptake in renal proximal tubular cells. Membrane transport function and cell death were evaluated by measuring phosphate uptake and trypan blue exclusion, respectively, in opossum kidney (OK) cells, an established proximal tubular cell line. $H_2O_2$ was used as a model oxidant. $H_2O_2$ inhibited the phosphate uptake in a dose-dependent manner over the concentration range of 0.1-0.5 mM. Similar fashion was observed in cell death. However, the phosphate uptake was more vulnerable to $H_2O_2$ than cell death, suggesting that $H_2O_2$-induced inhibition of phosphate uptake is not totally attributed to cell death. Decreasedphosphate uptake was associated with ATP depletion and inhibition of $Na^+$-pump activity as determined by direct inhibition of $N^+-K^+$-ATPase activity. When cells were treated with $H_2O_2$ in the presence of 0.05% SR, the inhibition of phosphate uptake and cell death induced by $H_2O_2$ was significantly attenuated. SR restored ATP depletion and decreased $Na^+-K^+$-ATPase activity, and this is likely responsible for the protective effect of SR on decreased phosphate uptake. The protective effect of SR was similar to the $H_2O_2$ scavenger catalase. SR reacts directly with $H_2O_2$ to reduce the effective concentration of the oxidant. The iron chelator deferoxamine prevented the inhibition of phosphate uptake and cell death induced by $H_2O_2$, suggesting that $H_2O_2$-induced cell injury is resulted from an iron-dependent mechanism. These results indicate that SR exerts the protective effect against $H_2O_2$-induced inhibition of phosphate uptake by reacting directly with $H_2O_2$ like the $H_2O_2$scavenger enzyme catalase, in OK cells. However, the underlying mechanism remains to be explored.
Nd : YAG LASER 조사가 치과 임플란트의 물성과 온도 상승에 미치는 영향

Pulsed Nd : YAG LASER has been applied to various fields in clinical dentistry including the treatment of peri-implantitis. However, LASER can affect properties of matter of dental implants which are important to maintaining the health of peri-implant tissue and can raise its temperature during lasing. So there have been warings of using LASER to treat peri-implantitis. But, the effects of laser on dental implants itself are not certain yet. So we measured the temperature rising, examined matter of properties by SEM and EDX before and after pulsed Nd : YAG lasing various intensity. 7 TPS implants and 7 HPS implants were used and pulsed Nd : YAG LASER was used in 0.3W, 1.0W, and 2.0W. 1. 2.0W LASER made polished neck portion of HPS implants reach $39.2^{\circ}C$ after 5 seconds lasing. 2. LASER made crater-like defects on plasma sprayed surface and surfaces were melted and divided by fragments after lasing. 3. There was no specific evidence of element change after lasing.
