A signed 3-partite graph is a 3-partite graph in which each edge is assigned a positive or a negative sign. Let G(U, V, W) be a signed 3-partite graph with $U\;=\;\{u_1,\;u_2,\;{\cdots},\;u_p\},\;V\;=\;\{v_1,\;v_2,\;{\cdots},\;v_q\}\;and\;W\;=\;\{w_1,\;w_2,\;{\cdots},\;w_r\}$. Then, signed degree of $u_i(v_j\;and\;w_k)$ is $sdeg(u_i)\;=\;d_i\;=\;d^+_i\;-\;d^-_i,\;1\;{\leq}\;i\;{\leq}\;p\;(sdeg(v_j)\;=\;e_j\;=\;e^+_j\;-\;e^-_j,\;1\;{\leq}\;j\;{\leq}q$ and $sdeg(w_k)\;=\;f_k\;=\;f^+_k\;-\;f^-_k,\;1\;{\leq}\;k\;{\leq}\;r)$ where $d^+_i(e^+_j\;and\;f^+_k)$ is the number of positive edges incident with $u_i(v_j\;and\;w_k)$ and $d^-_i(e^-_j\;and\;f^-_k)$ is the number of negative edges incident with $u_i(v_j\;and\;w_k)$. The sequences ${\alpha}\;=\;[d_1,\;d_2,\;{\cdots},\;d_p],\;{\beta}\;=\;[e_1,\;e_2,\;{\cdots},\;e_q]$ and ${\gamma}\;=\;[f_1,\;f_2,\;{\cdots},\;f_r]$ are called the signed degree sequences of G(U, V, W). In this paper, we characterize the signed degree sequences of signed 3-partite graphs.

Background: Variants of human papillomavirus (HPV) show more oncogenicity than do prototypes. The HPV16 Asian variant (HPV16As) plays a major role in cervical cancer of Asian populations. Some amino acid changes in the E6 protein of HPV16 variants affect E6 functions such as p53 interaction and host immune surveillance. This study aimed to investigate activities of HPV16As E6 protein on modulation of expression of miRNA-21 as well as interferon regulatory factors (IRFs) 1, 3, 7 and c-fos. Materials and Methods: Vectors expressing E6 protein of HPV16As (E6D25E) or HPV16 prototype (E6Pro) were constructed and transfected into C33A cells. HCK1T cells expressing E6D25E or E6Pro were established by transducing retrovirus-containing E6D25E or 16E6Pro. The E6AP-binding activity of E6 and proliferation of the transfected C33A cells were determined. MiR-21 and mRNA of interesting genes were detected in the transfected C33A cells and/or the HCK1T cells, with or without treatment by culture medium from HeLa cells (HeLa-CM). Results: E6D25E showed binding activity with E6AP similar to that of E6Pro. Interestingly, E6D25E showed a higher activity of miR-21 induction than did E6Pro in C33A cells expressing E6 protein. This result was similar to the HCK1T cells expressing E6 protein, with HeLa-CM treatment. The miR-21 up-regulation significantly corresponded to its target expression. Different levels of expression of IRFs were also observed in the HCK1T cells expressing E6 protein. Interestingly, when treated with HeLa-CM, IRFs 1, 3 and 7 as well as c-fos were significantly suppressed in the HCK1T cells expressing E6D25E, whereas those in the HCK1T cells expressing E6Pro were induced. A similar situation was seen for IFN-${\alpha}$ and IFN-${\beta}$. Conclusions: E6D25E of the HPV16As variant differed from the E6 prototype in its activities on epigenetic modulation and immune surveillance and this might be a key factor for the important role of this variant in cervical cancer progression.

The Expansion-Deflection(E-D) nozzle is a nozzle that has a performance gain through the altitude compensation effect by changing the effective area within the nozzle according to the altitude. An E-D nozzle has been known to reduce the length of the nozzle and achieve the payload gain of the launch vehicle. Due to the potential advantages of an E-D nozzle, related research has been carried out in the United Kingdom, Germany, Australia and Europe etc. In the UK, the flow characteristics of the E-D nozzle and the performance comparison with the dual-bell nozzle which is altitude compensation nozzle were studied. In order to understand the transition characteristics of the E-D nozzle in DLR, the transition characteristics according to the nozzle pressure ratio change were analyzed. In Europe, numerical study using the E-D nozzle concept on upper stage of the launch vehicle Ariane 5 ESC-B was carried out to confirm the possibility of payload gain according to the nozzle length reduction. In this paper, research trends of an E-D nozzle performed outside the country are classified and analyzed according to their characteristics and utilized as basic data of E-D nozzle research in the future.

Let $D{\subseteq}E$ be an extension of integral domains with characteristic zero, I be a nonzero proper ideal of D, and let H(D, E) and H(D, I) (resp., h(D, E) and h(D, I)) be composite Hurwitz series rings (resp., composite Hurwitz polynomial rings). In this article, we show that H(D, E) is an Archimedean ring if and only if h(D, E) is an Archimedean ring, if and only if ${\bigcap}_{n{\geq}1}d^nE=(0)$ for each nonzero nonunit d in D. We also prove that H(D, I) is an Archimedean ring if and only if h(D, I) is an Archimedean ring, if and only if D is an Archimedean ring.

La $d\'{e}marche$ et l'objet de cette recherche sont d'analyser, psychiquement, $th\'{e}oriquement$, les marques de $l'intersexualit\'{e}$ $pr\'{e}sentent$ en Orient et les $\'{e}l\'{e}ments$ intersexuels, binaires dans le $v\hat{e}tement$, et $\'{e}galement$ de comprendre $l'ambiguit\'{e}$ ou encore la fusion des $identit\'{e}s$ $sexu\'{e}es$, qui $pr\'{e}sente$ symboliquement a travers le $v\hat{e}tement$, dans la $soci\'{e}t\'{e}$ moderne. La base fondamentale dans la $th\'{e}orie$ de l'Orient est que l'univers se divise en Yin ($caract\`{e}re\;f\'{e}minin$) et Yang ($caract\`{e}re$ masculin) et que tout individu $poss\`{e}de$ $\'{e}galement$ ce couple, en quelque sorte un intersexuel qui s'ignore, avec des variations selon l'individu. En $d\'{e}finitive$, les compositions doubles des $\'{e}l\'{e}ments$ dans le $v\hat{e}tement$ oriental montraient $embl\'{e}matiquement$ nos $qualit\'{e}s$ doubles, masculins et $f\'{e}minins$, et les trois $\'{e}l\'{e}ments$ semblent primordiaux pour $l'\'{e}lucidation$ de la $pr\'{e}disposition$ du porteur : la couleur du tissu, sa forme et la texture du $v\hat{e}tement$. La mode d'auiourd'hui oscille entre masculin et $f\hat{e}minin$. Cette fusion de la mode semble le reflet d'une tendance intersexuelle et d'une fusion du genre. Ainsi, cette recherche est, $\grave{a}$ travers $l'\'{e}l\'{e}ment$ masculin ou $f\'{e}minin$ des $v\hat{e}tements$, pour tenter de discerner lesprit, l'intention et le $caract\`{e}re$ sexuel dominant du porteur.

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.

The recent works of architecture and interior design take on too various aspects to be classified as a trend or tendency. Many subjects, seeking the superiority between form and function in space which was the issue of Modernism, got to face the works which transcend the limitation of architecture due to the development of a variety of media and technology these days. In result, we could see the works which are to be Included into the category of art rather than architecture. This study starts from the thought that the common aspects of these works are based on the strangeness to pursue uniqueness, peculiarities or novelty. 'The subject of this study, $'D\acute{e}paysement'$, creates a new relation, disconnected from customs, to an architecture which became familiar through defragment, fixation and abstraction by the habitual relation and makes it reborn as an architecture which gives us a fantasy and a pleasure, by converting into the shape and image which are different from its original shape when a stimulus is given to an architecture. This study starts from the artistic aspect which has a close correlation with the architecture. The subject, $'D\acute{e}paysement'$ could be historically considered in two aspects - $D\acute{e}paysement$ of Surrealism which developed in paintings and Defamiliarization of Russian Formalism in the area of literature. This study is carried in a category of $D\acute{e}paysement$, focusing on the visual aspect of the architecture. This study is composed as follows: In chapter 2, a theoretical research is performed according to the definition and meaning of the $D\acute{e}paysement$ expression techniques, its origination and evolution, and type classification by the features of expression techniques in the era of Surrealism when $D\acute{e}paysement$ developed most vigorously in the area of art. In chapter 3, the system which formalizes the expression method of the techniques is presented, focusing on the case analysis of the artistic works according to the types of $D\acute{e}paysement$. In chapter 4, the application of the expression techniques of $D\acute{e}paysement$ is discussed by conducting cases analysis of the modern interior design.
