De notre temps, nous faisons face ${\grave{a}}$ un changement du $th{\hat{e}}atre$ dans son ensemble. Le $th{\acute{e}}atre$ contemporain tente de se $d{\acute{e}}marquer$ des autres formes artistiques, mais aussi des formes $litt{\acute{e}}raires$, lorsque la tendance est ${\grave{a}}$ la fusion des genres. Il existe ainsi de plus en plus de $th{\hat{e}}atre$ ${e}xp{\acute{e}}rimentaux$, $n{\acute{e}}s$ sous le nom de $th{\acute{e}}atre$ anthropologique, $th{\acute{e}}atre$ sociologique, $th{\acute{e}}atre$ ethnologique, $th{\acute{e}}atre$ ${\acute{e}}pist{\acute{e}}miologique$ ou $th{\acute{e}}{\hat{a}}tre$ interculturel. La $m{\acute{e}}thodologie$ doit elle s'adapter ${\grave{a}}$ cette tendance de fusion? Au lieu de trouver une $m{\acute{e}}thode$ d'anlyse de chaque "nouveaux genre" $n{\acute{e}}$ de la fusion, nous nous interrogeons sur la $m{\acute{e}}thodologie$ pour ${\acute{e}}tudier$ le $th{\hat{e}}atre$ dans son ensemble. Si une telle $m{\acute{e}}thodologie$ d'analyse existait, quelle serait la $diff{\acute{e}}rence$ avec la $m{\acute{e}}thodologie$ $d{\acute{e}}j{\grave{a}}$ existante? Et si elle n'existait pas, quelle serait la meilleure $m{\acute{e}}thodologie$ $adapt{\acute{e}}e$? Nous $consid{\acute{e}}rons$ la $m{\acute{e}}thode$ d'analyse de la didascalie comme nouvelle $m{\acute{e}}thodologie$ $adapt{\acute{e}}e$. En effet, la didascalie $conna{\hat{i}}t$ sans cesse des $m{\acute{e}}tamorphoses$ dans $l^{\prime}{\acute{e}}criture$. De nombreux $th{\acute{e}}oriciens$ ont $d{\acute{e}}velopp{\acute{e}}$ des $m{\acute{e}}thodes$ d'analyse afin de mieux comprendre les diverses formes de $th{\acute{e}}atre$ comtemporain et ses didascalies. Notre travail est de rassembler les ${\acute{e}}tudes$ des $diff{\acute{e}}rents$ $th{\acute{e}}oriciens$ et de les ordonner ; afin de proposer un outil d'analyse $adapt{\acute{e}}$ pour $l^{\prime}interpr{\acute{e}}tation$ des $pi{\grave{e}}ces$ du $th{\acute{e}}{\hat{a}}tre$ contemporain.

This research is a experimental study for the machining conditions of E. D. M. They were used Cu electrode and the various amplitude of current waves for the machining by E.D.M. By the analyse the characteristics of current, voltage, roughness of surface and over cut, the next results were obtained. E.D.M. machining time become to be more longer by the increasing the tensile stress. In case of NAK 55 as the composite resin, the machining time was more faster without the relationship for the tensile stress. And if it was more increased the amplitude of Ip, it has been more faster in the machining time and more poor in the surface roughness. But it was increased Ip with 5A, it has been increased 0.3 time in over cut. So, if we want to be the precision machining, the diameter of the electrode should be more smaller than the diameter of machined hole in workpiece with E.D.M.

In the present study, we investigated the antioxidant activity of Aucklandia lappa Decne (AL). Cell viability was measured in an MTT assay. Antioxidant effects were evaluated based on total polyphenol/flavonoid contents, ABTS radical scavenging activity, DPPH radical scavenging activity, SOD activity, and ROS content. AL was found not to be toxic at concentrations of 1 ㎍/mL, 10 ㎍/mL, and 100 ㎍/mL, respectively. The phenolic content was higher in AL-D than in AL-E, while the flavonoid content was higher in AL-E than in AL-D. AL-E exhibited higher ABTS radical scavenging activity than AL-D, and the EC50 values for BHA were 217.1 ㎍/mL in AL-D and 180.5 ㎍/mL in AL-E. AL-E also showed the highest DPPH radical scavenging activity. EC50 values for BHA were 114.2 ㎍/mL in AL-D and 95.8 ㎍/mL in AL-E. The SOD-like activity of AL-E was higher than that of AL-D. The EC50 values for ascorbic acid were 48.5 ㎍/mL in AL-D and 72.9 ㎍/mL in AL-E, indicating that both AL extracts have a SOD activity higher than that of ascorbic acid. AL-E reduced relatively more ROS than AL-D. With 100 ㎍/mL AL-E, the reduction level was almost similar to that of dexamethasone. Our results demonstrate that AL have antioxidant effects, and we believe that they could be very valuable as raw materials for anti-aging products, based on their antioxidant activity.

Dans le contentieux m$\acute{e}$dical, il est difficile de prouver l'existence d'un lien de causalit$\acute{e}$ entre la faute m$\acute{e}$dicale et les pr$\acute{e}$judices subis par la victime. R$\acute{e}$partir bien de façon raisonnable la charge de la preuve du lien causal est alors une des questions pr$\acute{e}$occup$\acute{e}$es par la doctrine cor$\acute{e}$enne. La Cour supr$\hat{e}$me cor$\acute{e}$enne semble toutefois facilliter l'indemnisation des victimes dans les cas o$\grave{u}$ la responsabilit$\acute{e}$ du m$\acute{e}$decin a ${\acute{e}}t{\acute{e}}$ mise en cause, et cela en admettant des fois une solution op$\acute{e}$rant un renversement de la charge de la preuve du lien causal. Une telle attitude a ${\acute{e}}t{\acute{e}}$ m$\hat{e}$me affirm$\acute{e}$e dans un arr$\hat{e}$t rendu r$\acute{e}$cemment en cas de dommage caus$\acute{e}$ par le fait du produit de sant$\acute{e}$, notamment pour le cas de contamination virale par voie de transfusion. La Cour a $\acute{e}$galement reconnu que l'action se pr$\acute{e}$scrit $\grave{a}$ partir du moment de la consolidation du pr$\acute{e}$judice. Aux termes de cette $\acute{e}$tude, on pourra constater que le juge français reconna$\hat{i}$t aussi l'assouplissement de la charge de la preuve du lien de causalit$\acute{e}$ en mati$\acute{e}$re d'action m$\acute{e}$dicale. Il faudra toutefois souligner que le ph$\acute{e}$nom$\acute{e}$ne ne soit pas g$\acute{e}$n$\acute{e}$ralis$\acute{e}$ en droit français, d'autant plus que la pr$\acute{e}$somption de l'existence de la causalit$\acute{e}$ en la mati$\grave{e}$re a $\acute{e}$t$\acute{e}$ admise de mani$\grave{e}$re restrictive par la l$\acute{e}$gislation sp$\acute{e}$cifique. Tel $\acute{e}$tait notamment le cas pour les accidents de la contamination par le virus du sida ou de l'h$\acute{e}$patite C survenus apr$\grave{e}$s la transfusion. En d$\acute{e}$finitive, on peut dire qu'en droit français, le principe est maintenu en cas de manquement $\grave{a}$ une obligation de r$\acute{e}$sultat n$\acute{e}$e du contrat m$\acute{e}$dical, tandis que la Cour de cassation admet parfois en mati$\grave{e}$re de droit commun de la responsabilit$\acute{e}$ contractuelle la pr$\acute{e}$somption de causalit$\acute{e}$ en cas d'inex$\acute{e}$cution des obligations de r$\acute{e}$sultat. En fait, la pr$\acute{e}$somption de causalit$\acute{e}$ dans le contentieux m$\acute{e}$dical pourra mener les m$\acute{e}$decins $\grave{a}$ se diriger vers les traitements d$\acute{e}$fensifs. Cette situation peut m$\hat{e}$me conduire $\grave{a}$ emp$\hat{e}$cher le d$\acute{e}$veloppement de la science m$\acute{e}$dicale, enfin $\grave{a}$ une situation d$\acute{e}$savantageuse aux patients. Il y a alors lieu de se m$\acute{e}$fier des int$\acute{e}$r$\hat{e}$ts d$\acute{e}$s$\acute{e}$quilibr$\acute{e}$s entre le m$\acute{e}$decin et le patient. De ce point de vue, on peut estimer que le droit français donne des suggestions aux juristes cor$\acute{e}$ens dans la recherche des solutions plus ad$\acute{e}$quates en ce qui concerne la charge de la preuve du lien causal en mati$\acute{e}$re de responsabilit$\acute{e}$ m$\acute{e}$dicale.

Estradiol-$17{\beta}(E_2)$와 2,4-dichlorophenoxy acetic acid (2, 4- D)가 난황 전구물질의 합성에 미치는 영향을 넙치 Paralichthys olivaceus 간세포의 초대 배양을 통하여 조사하였다. 배양간세포의 생존율은 배양온도 $27^{\circ}C$에 서 가장 높게 나타났으며, $15^{\circ}C$에서는 생존율이 급격히 감소하여 약 50%의 생존율을 나타내었다. $E_2$에 의한 VTG 의 합성은 $10^{-6}M$에서 최대치를 나타내었다. 2, 4-D $10^{-7}\sim10^{-5}M$의 첨가에 의해 VTG의 합성은 이루어지지 않았다. 그러나, 저농도인 $10^{-8}M$에서는 VTG의 합성이 증가하였다. $E_2$ 및 2, 4-D에 의해 합성된 VTG는 $10^{-6}M$ tamoxifen의 첨가에 의해 유의하게 억제되었다 (P<0.01). 본 연구 결과에서 $E_2$와 2, 4-D의 동시 첨가는 VTG의 합성을 억제하지 않았다. 이러한 결과는 2, 4-D의 작용이 $E_2$와 유사한 작용을 가지지만, VTG의 합성에 있어서 $E_2$ 수용체에의 작용 양식은 서로 다른 것으로 추정된다.

Solution to the diffusion layer for the first order reaction at a droping mercury electrode (D.M.E.) is presented. Equations are derived for polarographic currents for the reactions at the D.M.E. A factor which is applicable to the D.M.E. is derived, when we use the equations of the polarographic currents for the reactions at a plane electrode(P.E.), and the rate constants of the backward reactions are negligibly small. Polarographic currents from a combination of diffusions and reactions are obtained at the D.M.E. with special approximation. Rate constant for the reaction of ferrous ion with hydrogen-peroxide is determined at the D.M.E.,using the data of Kolthoff and Perry. The agreement of the equation with the data of Kolthoff and Perry for the kinetic current of ferric ion in the presence of hydrogen-peroxide is good. Ratios of diffusion layer at the D.M.E. to the diffusion layer at the P.E. are discussed and show that, when the rate constants of the backward reactions for the first order reactions are larger than 1/0.05 sec-1. and drop-time about 3 sec., these ratioes are about one.
