La langue est un des ${\acute{e}}l{\acute{e}}ments$ $privil{\acute{e}}gi{\acute{e}}s$ de la $r{\hat{e}}verie$ chez Bachelard. La langue est une force fondamentale de l'imagination. D'une part, elle garde son propre valeur dans le processus de l'imagination, et d'autre part elle forme sa propre image. La $priorit{\acute{e}}$ de langue chez Bachelard a, en effet, quelque liaison avec la notion de Logos qui avait ${\acute{e}}t{\acute{e}}$ $trait{\acute{e}}$ depuis longtemps comme $v{\acute{e}}rit{\acute{e}}$ ${\acute{e}}ternelle$ dans la $m{\acute{e}}taphysique$ occidentale. Cependant, la notion de logos de Bachelard se $diff{\grave{e}}re$ de celle de $m{\acute{e}}taphysique$ occidentale. Tandis que la $m{\acute{e}}taphysique$ traditionnelle traite le logos comme un but ${\acute{e}}ternel$ de sa $m{\acute{e}}ditation$, Bachelard donne l'importance sur la $capacit{\acute{e}}$ linguistique et imaginaire du logos. Le $logosph{\grave{e}}re$ est un des exemples qui montre bien la $diff{\acute{e}}rence$ entre la notion de logos de Bachelard et celle de $m{\acute{e}}taphysique$ traditionnelle. Le $logosph{\grave{e}}re$ est un $n{\acute{e}}ologisme$ de Bachelard qui est fait pour $d{\acute{e}}signer$ $l^{\prime}atmosph{\grave{e}}re$ verbal de la $soci{\acute{e}}t{\acute{e}}$ contemporaine $gr{\hat{a}}ce$ ${\grave{a}}$ l'emission de radio. Bachelard comprend le $ph{\acute{e}}nom{\grave{e}}ne$ de radio en tant que $r{\acute{e}}alisation$ de $Psych{\acute{e}}$ dans la vie quotidienne. C'est $gr{\hat{a}}ce$ ${\grave{a}}$ la technologie moderne que nous pouvons avoir l'univers de langue plus facilement par rapport aux $si{\grave{e}}cles$ $pr{\acute{e}}c{\acute{e}}dents$. Selon Bachelard, la radio n'est pas un simple instrument de communication. C'est une porte pour entrer dans la $r{\hat{e}}verie$ universelle. La radio est une voix du monde qui exprime notre inconscient. Quand un $r{\hat{e}}veur$ $r{\hat{e}}ve$, son $r{\hat{e}}verie$ se $d{\acute{e}}veloppe$ en se discutant avec le monde. Alors, quand nous $r{\hat{e}}vons$, nous parlons au monde et nous ${\acute{e}}coutons$ du monde, de sorte que nous devenons les citoyens du $logosph{\grave{e}}re$. Dans son oeuvre Sur la Grammatologie, J. Derrida critique la $m{\acute{e}}taphysique$ occidentale en la intitulant logocentrisme. Derrida pense que la philosophie occidentale a comme le but final la $pr{\acute{e}}sence$ de logos. Cette $pr{\acute{e}}sence$ de logos ne peut ${\hat{e}}tre$ $r{\acute{e}}alis{\acute{e}}e$ que par la langue de la voix, non pas par la langue de $caract{\grave{e}}re$. $D^{\prime}o{\grave{u}}$ vient le logocentrisme ou le phonocentrisme de $m{\acute{e}}taphysique$ occidental. Mais Derrida pense que le logocentrisme n'est qu'un autre aspect de l'ethnocentrisme ${\acute{e}}troit$ de l'occident. La notion de $logosph{\grave{e}}re$ de Bachelard a quelques ressemblances avec logocentrisme par ses apparences. Cependant, elles ont une $diff{\acute{e}}rence$ fondamentale depuis leur $d{\acute{e}}part$. Tandis que logocentrisme $tra{\hat{i}}te$ la parole en tant que $mani{\grave{e}}re$ d'expression de raison qui est une puissance fondamentale de l'homme, Bachelard pense que la parole est un $r{\acute{e}}sultat$ d'une opposition et fusion de notre raisons et parole. Bachelard pense que la parole est une $r{\acute{e}}alisation$ de l'image qui est l'essence de notre $psych{\acute{e}}$. Pour lui, la parole, la quintessence de $logosph{\grave{e}}re$, est le champ de l'imagination $d^{\prime}o{\grave{u}}$ jaillissent les images. C'est pour cela que $logosph{\grave{e}}re$ se situe ${\grave{a}}$ l'antipode de logocentrisme. $Logosph{\grave{e}}re$ nous fournit un espace de $r{\hat{e}}verie$ de langue. Notre $soci{\acute{e}}t{\acute{e}}$ contemporaine $fourr{\acute{e}}e$ des images visuelles creuses est $d{\acute{e}}pouill{\acute{e}}e$ de plus en plus des espaces de $r{\hat{e}}veries$. C'est une des raisons que le $logosph{\grave{e}}re$ de Bachelard doit ${\hat{e}}tre$ $r{\acute{e}}activ{\acute{e}}$ aujourd'hui.

Polyphenylvinylketone (PPVK) having a carbonyl group at the side chain was blended with polystyrene (PS) to investigate the effect of vinylketone polymers on the photodegradability of the blend as a function of U.V. irradiation time. Hydrogenated polyphenylvinylketone (PPVK(H)) which is made by hydrogenation of some of the carbonyl groups in PPVK was also blended with PS to check the role of carbonyl carbonyl group in the process of photodegradation. Photodegradability was also investigated for blends of PS with polymethylvinylketone (PMVK) and for copolymers of styrene and methylvinylketone (SMVK) to compare the effect of copolymerization versus blending on photodegradability. PPVK showed higher photodegradability than PPVK(H), which followed that the blends of PS with PPVK gave higher degradability than with PPVK(H). In view of the fact that PPVK(H) is a partially hydrogenated version of PPVK, carbonyl group was confirmed to be involved in the photodegradation mechanism. When polymethylvinylketone (PMVK) was blended with PS, this blend showed a higher degradability than PS/PPVK blend. Therefore the highest photodegradability was achieved when PS was blended with PMVK followed by PPVK and PPVK(H) in order. When SMVK was UV irradiated, it showed the highest photodegradability than any blends mentioned above. Therefore, copolymerization was proved to be the better means of photodegradation than blending.

Anthracycline antibiotics doxorubicin (DXR) is clinically important cancer therapeutic agent produced by Streptomyces peucetius. DXR result by further metabolism of rhodomycin D (RHOD) and require a deoxy-sugar component for their biological activity. In this study, production of TDP-L-daunosamine and its attachment to ${\varepsilon}$-rhodomycinone (RHO) to generate RHOD has been achieved by bioconversion in Streptomyces venezuelae that bears eleven genes. S. peucetius seven genes (dnmUTJVZQS) were transformed by plasmid and S. venezuelae two genes desIII, IV and two more S. peucetius drrA, B genes were integrated into chromosomal DNA. To generate the feeding substrate RHO, 6L S. peucetius grown on agar plate was harvested, extracted with organic solvent and then purified using preparative HPLC. Recombinant S. venezuelae grown on agar plate containing RHO was harvested and its n-butanol soluble components were extracted. The glycosylated product of aromatic polyketide RHO using heterologous host S. venezuelae presents the minimal information for TDP-L-daunosamine biosynthesis and its attachment onto aglycone. Moreover, the structure of auxiliary protein, DnrQ, was predicted by fold recognition and homology modeling in this study. This is a general approach to further expand of new glycosides of antitumor anthracycline antibiotics.

Les avis des philosophes sur la mort sont $diff{\acute{e}}rentes$ selon leurs visions du monde. Certains essaient de surmonter la peur sur la mort, en $n{\acute{e}}gligeant$ la mort, et certains essaient de vivre le vraie vie par la $m{\acute{e}}ditation$ de la mort. Chez Kierkegaard la notion de la mort se $pr{\acute{e}}sente$ comme key-world $tr{\grave{e}}s$ important, et cela signifie qu'il parle par la mort une vie $s{\acute{e}}rieuse$ et vraie. Pour Kierkegaard la mort signifie d'abord la mort de la vie mondaine ou la $n{\acute{e}}gation$ de soi, cela est en faveur de sa conception de la nature humaine $o{\grave{u}}$ l'homme est fondamentalement un ${\hat{e}}tre$ $probl{\grave{e}}matique$ et ${\grave{a}}$ la fois ceuli qui a un rapport avec $l^{\prime}{\acute{e}}ternel$. Le $d{\acute{e}}sespoir$ de l'homme sur la vie $pr{\acute{e}}sente$ peut devenir 'la maladie qui entraîne la mort' c'est-${\grave{a}}$-dire la mort spirituelle, mais il peut donner aussi une chemin par laquelle l'homme se dirige en tant qu'individu vers l'Absolu. Chez lui ${\hat{e}}tre$ $s{\acute{e}}rieux$ signifie devenir existentiellement par la $n{\acute{e}}gation$ de soi. Et l'absence de la $sinc{\acute{e}}rit{\acute{e}}$ signifie l'absence de soi en tnat $qu^{\prime}{\hat{e}}tre$ spirituel. Ainsi la $pens{\acute{e}}e$ $s{\acute{e}}rieuse$ sur la mort $n^{\prime}{\acute{e}}tant$ autre chose que de penser la mort comme la partie de $l^{\prime}{\hat{e}}tre$ $pr{\acute{e}}sent$, elle devient la source ${\acute{e}}nergique$ qui permet de vivre pleinement le $pr{\acute{e}}sent$ comme $r{\acute{e}}alit{\acute{e}}$ $li{\acute{e}}$ ${\acute{a}}$ $l^{\prime}{\acute{e}}ternit{\acute{e}}$. Sa $pens{\acute{e}}e$ $s{\acute{e}}rieuse$ sur la mort permet d'avoir une conviction religieuse par laquelle l'homme peut penser la mort corporelle comme aventure $li{\acute{e}}e$ ${\grave{a}}$ $l^{\prime}{\acute{e}}ternit{\acute{e}}$ et par laquelle l'homme peut penser aussi la vie $apr{\grave{e}}s$ la mort comme vraie vie que les justes avaient $d{\acute{e}}sir{\acute{e}}s$. Cette $pens{\acute{e}}e$ de Kierkegaard sur la mort signifie le sens $m{\acute{e}}taphysique$ sur la mort au sens $o{\grave{u}}$ elle est une $r{\acute{e}}alit{\acute{e}}$ $v{\acute{e}}cue$, et aussi la $pens{\acute{e}}e$ qui ${\acute{e}}claircit$ la sagesse des philosophes antiques ${\grave{a}}$ la perspective $chr{\acute{e}}tienne$ qui dit philosopher, c'est apprendre ${\grave{a}}$ mourir.

The purpose of this study was to evaluate the human pulpal response to Dentin Bonding Desensitizer. Class V cavities were prepared on the buccal surfaces of the first premolars and Dentin Bonding Desensitizer(ALL-BOND Desensitizer, Bisco, Inc. U.S.A.) was applicated in ten experimental teeth, or ZOE(PROPAC, GC Co. TOKYO, JAPAN) cement in eight control teeth and cavities were filled with light curing glass ionomer(Fuji II LC, GC Co., TOKYO, JAPAN). At 3-day and 25-day postoperative interval. pulpal response was observed and evaluated histologically with light microscope. The results were as follows. ; 1. At 3-day postoperative interval, the control teeth were grade 1 inflammatory cell response and grade 1 connective tissue response. 2. At 25-day postoperative interval, all control teeth were grade 1 inflammatory cell response and in three control teeth grade 1 connective tissue response were observed, and one teeth showed grade 2 connective tissue response. 3. At 3-day postoperative interval, the experimental teeth were grade 1 inflammatory cell response and grade 1 connective tissue response. Below the cavity, a few inflammatory cell(PMNs) in odontoblastic layer, increased blood vessels and pulpal cells were seen and this pulpal response was similar to control teeth. 4. At 25-day postoperative interval, in four experimental teeth grade 1 inflammatory cell response and grade 1 connective tissue response were observed, and one experimental teeth showed mild inflammatory response. 5. At 3-day and 25-day postoperative interval, no reparative dentin deposition was seen. 6. Both experimental and control group, pulpal response showed difference between 3 and 25-day of postoperative interval. In control teeth, increased predentin and pulpal cells were seen and in experimental teeth, congestion of blood vessels and increased pulpal cells were seen. In conclusion, the pulpal irritation due to this Dentin Bonding Desensitizer was not severe, and it was considered that the agent was not harmful to the human pulp.

Fracture of the sternum has been considered as a serious injury and also associated with major complications such as myocardial, major thoracic vascular, and spinal injury. Retrospective datas from blunt trauma victims admitted to our hospital were analyzed to determine significance of sternal fractures and possible associated injures. 101 sternal fractures by blunt trauma were admitted from january, 1986 to december, 1995. Frequency was about 3.51 olo of the nonpenetrating chest trauma. The ratio of male to female was 1.82 versus 1. Most common cause in the stemal fracture was high decelerating injury(73 cases). Most common fracture site was sternal body(75 cases). Average days of adm ssion were 26 days. Abnormal ECG findings were sinus bradycardia(Teases), complete or incomplete RBBB(6 cases), sinus tachycardia(4 cases), specific S-T change(3 cases), 1st degree A-V block(2 cases), LVH(1 case), PVC(1 case), and Low voltage(1 case). CPK-MB was increased about 32.Lolo of sternal fractures. Except of expired 2 patients, patients were treated with conservative treatment(94 cases) and open reductions & steel wire fixations(5 cases). Complication after operation was wound infection(1 case). Causes of death were 1 hypovolemia and 1 acute respiratory distress syndrome. In conclusion, although sternal fracture is less frequent, and mostly treats with conservative treatment, it shoed be carefully observed because of critical associated injuries.

Steel-concrete composite structures have been extensively used in building, bridges, and other civil engineering infrastructure. Shear stud connectors between steel and concrete are essential in composite members to guarantee the effectiveness of their behavior in terms of strength and deformability. This study focuses on investigating the shear stiffness of headed studs embedded in several types of concrete with wide range of compressive strength, and their effects on the elastic behavior of steel-concrete composite girders were evaluated. Firstly, totally 206 monotonic push-out tests from the literature were reviewed to investigate the shear stiffness of headed studs embedded in various types of concrete (NC, HPC, UHPC etc.). Shear stiffness of studs is defined as the secant stiffness of the load-slip curve at 0.5V_u, and a formulation for predicting defined shear stiffness in elastic state was proposed, indicating that the stud diameter and the elastic modulus of steel and concrete are the main factors. And the shear stiffness predicted by the new formula agree well with test results for studs with a diameter ranging from 10 to 30 mm in the concrete with compressive strength ranging from 22.0 to 200.0MPa. Then, the effects of shear stiffness on the elastic behaviors of composite girders with different sizes and under different loading conditions were analyzed, the equations for calculating the stress and deformation of simply supported composite girders considering the influence of connection's shear stiffness were derived under different loading conditions using classical linear partial-interaction theory. As the increasing of shear stiffness, the stress and deflection at the most unfavorable section under partial connected condition tend to be those under full connected condition, but the approaching speed decreases gradually. Finally, the connector's shear stiffness was recommended for fully connection in composite girders with different dimensions under different loading conditions. The findings from present study may provide a reference for the prediction of shear stiffness for headed studs and the elastic design of steel-concrete composite girder.

The effect on sow milk of variable levels of cassava in lactating sow diets was analyzed in an attempt to explain the beneficial effects reported by producers of including cassava as a basal feed. Twenty crossbred lactating sows were randomly assigned to five dietary treatments. The treatments were: i) broken rice (BR) as the basal feed (BR100), ii) 50% of BR replaced with cassava chip meal (CCM) (CM50), iii) 75% of BR replaced with CCM (CM75), iv) CCM as the basal feed (CM100), and v) dried boiled cassava chips (CCB) as the basal feed (CB100). The hydrocyanide (HCN) content of CCB was reduced to be intermediate between HCN in the no cassava (BR100) and the 50% cassava (CB50) diets. Hydrocyanide was 0.54, 3.24, 4.41, 5.43 and 1.77 ppm in the BR100, CM50, CM75, CM100 and CB100 diets, respectively. Increasing cassava did not affect feed intake (p>0.05), but increased HCN intake (p<0.01). Milk composition was analyzed for protein, fat, lactose, solids not fat (SNF) and total solids (TS). Milk quality was analyzed for total microbes, coliform bacteria, thiocyanate ($SCN^-$), lactoperoxidase (LPO), and glutathione peroxidase (GPx) activity. At farrowing, sow milk composition was not affected by experimental diets (p>0.05), but milk $SCN^-$ increased as the intake of HCN increased in sows diets (p<0.01), $r^2$ = 0.96. At mid-lactation (day 14), milk composition was not affected (p>0.05). The milk quality levels of $SCN^-$ were 9.4, 10.3, 10.5, 11.6 and 9.1 ppm for the BR100, CM50, CM75, CM100 and CB100 diets, respectively (p = 0.01). The LPO contents were 16.41, 42.13, 51.42, 53.94 and 22.81 unit/L, respectively (p = 0.03). There was no GPx activity found in sow milk. When BR was replaced with cassava meal, total microbes and coliforms were reduced 78% and 87%, respectively, by the influences of HCN. The reported beneficial effects of cassava chip meal as a basal feed in lactating sow diets is manifested by improved performance of suckling pigs. This is due to beneficial, non-toxic levels of HCN in the diets. Besides passing HCN to suckling pigs in the form of $SCN^-$, sow milk may also benefit suckling pigs with the observed (day 14) increase in lactoperoxidase content and reduction in coliform bacteria.
