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.

Synthesis of $PbLaTiO_{3}$ : Mn powders containing La and Mn was carried out using $PbO,\;TiO_{2},\;La_{2}O_{3}\;and\;MnO_{2}$ as starting materials by hydrothermal method. In the synthesis of single phase $PbLaTiO_{3}$ : Mn powder containing La and Mn, the optimal x value corresponding to La substitution was 0.01 which corresponds to $0.99(Pb_{1-x}La_{2x/3}TiO_{3})+0.01MnO_{2}$. The optimal conditions for the preparation of the powder synthesis were 8 M-KOH solvent of hydrothermal solvent, $270^{\circ}C$ of reaction temperature and 24 hrs of run time. It was found that the synthesized powders had spherical morphology with average particle size of 70 nm and specific surface area of $5.5\;m^{2}/g$.

Single crystalline films of La doped YIG(yttrium iron garnet) were grown by the liquid phase epitaxy. The lattice constants of films obtained by DCD(double crystalline diffractometer) measurement increased with increasing La contents in films. In particular, lattice constants of films grown wiht Y/La=20 solution were nearly same as those of GGG (gadolinium gallium garnet) substrate. The saturation magnetization measured with VSM (vibrating sample magnetometer) was about 1750Gauss which is the same as that of pure YIG irrespective of La contents in films. FMR(ferromagnetic resonance) linewidth of La doped YIG was smaller than that of pure YIG. Since appropriate La doping decreases the lattice mismatch between film and substrate, the FMR linewidth was Y/La=20 in this experiment.

Al2O3/(5~20vol%)LaAl11O18 composites in which the second phase was dispersed with a elongated grain shape were fabricated using Al2O3 and La2O3 composition by hot-pressing. In order investigate the in-fluence of LaAl11O18 on the toughening of LaAl11O18 on the toughening of Al2O3 matrix composites AE(acoustic emission) analysis was con-ducted together with an evaluation of fracture toughness using of SEPB technique. The degree of AE events occurred in composites were more than those in monolithic alumina. The occurrences of AE event increased with increasing the amount of LaAl11O18 phase in the Al2O3/LaAl11O18 composite is two times higher compared to monolithic alu-mina. The main toughening mechanism was attributed to the bridging of LaAl11O18 grains at tip of pro-pagating crack.

Pb(Mg$_{1}$3/Nb$_{2}$3)O$_{3}$[PMN]-PbTiO$_{3}$[PT]계 고용체의 상경계조성(MPB)영역에 대해 La을 첨가하여 변성시킨 La변성 (1-x)PMN-xPT(x=0.35) 고용체를 만들어 온도-유전율 특성, 전계유기 분극특성 및 변위특성을 조사하였다. PMN-PT의 상경영역의 조성인 x=0.35에 대해 La함량을 0-10at%까지 변화시켰다. PMN-PT계 고용체에서 PT 의 함량이 증가함에 따라 전계유기변위 및 히스테리시스 특성이 모두 증가하였다. 전계유기변위 값 $\varepsilon$ 는 능면정과 정방정의 공존영역인 MPB(x=0.35)조성에서 가장 높은 값($\varepsilon$ = 2 x $10^{-3}$)을 보여 주었다. MPB조성에 대해 La을 첨가한 계의 전계유기변위를 조사한 결과 La의 첨가량이 적을 때 (La=0-5at%)는 La의 함량이 증가함에 따라 히스테리시스 특성이 감소하였고 $\varepsilon$ 은 증가하여 고성능의 액튜에이터 재료에 적합한 조성물로 기대된다.

The sintering phenomena and piezoelectric properties of PZT ceramics of composition $Pb(Zr_{0.54} Ti_{0.46})O_3$ were investigated when a small quantity of $La_2O_3$ , $LaMnO_3$, $LaCrO_3$ were added. The unwanted chemical composition change in PZT during sinterin porces du to PbO evaporation poses a severe problem in PZt manufacturinig. It is observed tat an addition of small amount of $LaMnO_3$ to PZT markedly decreases the evaporation of PbO during sintering . The green compact of (1-x) PZT.xLaMnO3(x=0.02~0.10) could be sintered of under O2 atmosphere alone with no significant loss of PbO. The planar coupling factor kp of the sintered $0.98Pb(Zr_{0.54} Ti_{0.46})O_{3.0.02}LaMnO}3$ is similar to that of commercial PZT 6A. Microstructure investigation shows that part of sintering process of $Pb(Zr, Ti)O_3$.$LaMnO_3$ system progresses via liquid phase sintering. It is believed that the evaporation of PbO in PZT sintering is restricted by the addition of $LaMnO_3$ due to the above phenomena. Furthermore the solid solution of $LaMnO_3$ in PZT causes diffuses phase transition.

The solubilities of different multicomponent lanthanide oxide (Ln₂O₃) solid solutions including binary (Ln₁ and Ln₂ = La, Nd, Eu, or Tm), ternary (Ln₁, Ln₂, and Ln₃ = La, Nd, Eu, or Tm), and higher systems (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) were studied after aging for four weeks at 60℃. Our recent study revealed that the phase transformations in binary ((La, Nd) and (La, Eu)) and ternary (La, Nd, Eu) systems are responsible for the formation of (La, Nd)(OH)₃, (La, Eu)(OH)₃, and (La, Nd, Eu)(OH)₃ solid solutions, respectively. The variations in the mole fractions of La³⁺, Nd³⁺, and Eu³⁺ in the sample solutions of these hydroxide solid solutions indicated that a thermodynamic equilibrium might account for the apparent La, Nd, and Eu solubilities. Conversely, the binary and ternary systems containing Tm₂O₃ as the heavy lanthanide oxide retained the oxide-based solid solutions, and their solubility behaviors were dominated by their congruent dissolutions. In the higher multicomponent system, the X-ray diffraction patterns of the solid phases, before and after contact with the aqueous phase indicated the formation of a stable oxide solid solution and their solubility behavior was explained by its congruent dissolution.

El presente trabajo tiene como objetivo proporcionar una explicación simplificada pero suficiente sobre el uso de las formas pronominales de tratamiento en los países de habla española, y hacer una propuesta para la enseñanza de los pronombres de tratamiento en la enseñanza del español en Corea. En la actualidad, en el mundo hispánico existen varios sistemas de tratamiento pronominal. La distribución dialectal de sus formas es bastante complicada. En la norma de España se usa el tú para el trato informal en oposición con el usted para el trato formal. Mientras tanto, en Hispanoamérica se usan el tú y el vos para el trato informal, y el usted para el trato formal. Sin embargo, la mayoría de las gramáticas didácticas y manuales no ofrece una explicación suficiente en cuanto a las diferencias de las formas y el uso de los pronombres de tratamiento. En Corea, en la mayoría de las clases de español se enseñan sólo la norma de España, que es minoitaria entre la comunidad global de hispanohablantes. Eso no les permitiría a los estudiantes tener una interacción exitosa con personas que dominen otras normas del tratamiento pronominal. Para que los alumnos tengan una competencia comunicativa que sea lo más universalmente válida, es necesario ofrecer una perspectiva de los fenómenos lingüísticos y culturales que toman en cuenta las variedades del sistema del tratamiento pronominal que se usan hoy en día en el dominio hispánico. Por último, los intereses y el nivel de los alumnos son variables que determinan qué o cuánto hacer en la enseñanza de las formas pronominales de tratamiento.

In order to study the reaction behaviors of bovine $\alpha$-lactalbumin ($\alpha$-La), $\beta$-lactoglobulin ($\beta$-Lg), and their mixtures during heat treatment, samples were analyzed using native-polyacrylamide gel electrophoresis (Native-PAGE), sodium dodecylsulfate (SDS)-PAGE, and two-dimensional (2-D)-PAGE. The electrophoresis demonstrated that the loss of native-$\alpha$-La increased as temperature increased, and that the loss of apo-$\alpha$-La was slightly higher than that of holo-$\alpha$-La. The tests also showed that during heat treatment, a mixture of $\alpha$-La and $\beta$-Lg was less stable than $\alpha$-La alone. As such, it was assumed that $\beta$-Lg induced holo-$\alpha$-La to be less stable than apo-$\alpha$-La during heat treatment. The reaction behavior of $\alpha$-La (holo-, apo-form) during heat treatment showed similar patterns in the 2-D-PAGE electropherogram, but the mixture of $\alpha$-La and $\beta$-Lg created new bands. In particular, the results showed a greater loss of native $\alpha$-La in the holo-$\alpha$-La and $\beta$-Lg mixture than in the apo-$\alpha$-La and $\beta$-Lg mixture. Thus, it can be concluded that the holo-$\alpha$-La and $\beta$-Lg mixture was more intensively affected by heat treatment than other samples, and that free sulphydryl groups took part in the heat-induced denaturation.

The bioconversion of linoleic acid (LA) to conjugated linoleic acid (CLA) was investigated to examine LA-adaptation of Bifidobacterium breve KCTC 3461 to additions of 1 to 5 mg/mL of LA overtime. To induce LA-adaptation, B. breve KCTC 3461 was treated with LA, according to three schemes. For LA-adapted B. breve the maximum concentration of CLA, $300\~350{\mu}g/mL$, was obtained in cys-MRS medium containing 1 mg/mL of LA. The CLA production significantly increased with increasing LA concentration, from 1 to 4 mg/mL, but the conversion of LA to CLA gradually decreased. The CLA production capability of B. breve, and its tolerance, improved significantly with LA-adaptation. The addition of LA (1 mg/mL) into the culture broth after 24 h of cultivation in a 100-mL media bottle was most effective at promoting CLA production. In a 2.5-L stirred-tank bioreactor, the observed conversion and productivity of $56.6\%\;and\;35.4{\mu}gmL^{-1}h^{-1}$, respectively, by LA-adapted B. breve were approximately 6.6 and 9.8 times higher than those of LA-unadapted B. breve.
