In this study, we discuss about the printed reflectarray antenna design for parabolic reflector volume reduction. For this, we simulated and measured the phase characteristics of the unit array element of reflectarray antenna using waveguide simulator. As a results, the maximum phase variation is $298^{\circ}$ by simulation, the average phase variation is $309^{\circ}$ by measurement in 10GHz. And the printed Reflectarray antenna gain is 28.3dBi, 3dB beamwidth is E-plane $5.1^{\circ}$, H-plane $5.2^{\circ}$, sidelobe level is E-plane -11.4dB, H-plane -17.6dB.

PURPOSE: The aim of this study was to investigate the effects of distal movement on shoulder muscle activation during diagonal pattern of exercises. METHODS: Seventeen healthy male participants volunteered to participate. Five muscles of shoulder were investigated during standing performance of diagonal shoulder exercises with and without visual trace. Two patterns of the diagonal exercises were used as diagonal 1 flexion and extension (D1F-E), and diagonal 2 flexion and extension (D2F-E). Two way repeated measures analysis of variance was used, which the factor was the presence of distal movement and exercise variations. RESULTS: The average muscle activity values of the lower trapezius and anterior deltoid are higher with the D2F-E, compared to the D1F-E (p<.05). The distal movement effect was observed within included all muscles except the lower trapezius, which the values are significantly greater in exercise with distal movement (P<.05). All significant increase of the muscles during the exercise with distal movement condition showed over 0.9 for the observed power in present study. CONCLUSION: Present result suggested that the diagonal pattern of exercise with distal movement has additional advantages of activating the scapulothoracic muscle as well as glenohumeral muscles. In addition, the D2F-E exercise pattern is effective for activating lower trapezius and anterior deltoid muscles.

We investigated the structural parameters of a sample of 30 dwarf galaxies(15 dEs and 15 dS0s) in the Virgo Cluster using i-band images from the Sloan Digital Sky Survey Data Release 4. Among 28 galaxies for which surface brightness profiles were derived from ellipse fittings, 23 galaxies had a single component that was adequately described by a generalized $S\acute{e}rsic$ function with a shape parameter ranging from n=0.5 to 2, while 5 galaxies(2 dEs and 3 dS0s) had bulge and disk components that were fitted by a generalized $S\acute{e}rsic$ function and an exponential function, respectively. Since the majority of dwarf galaxies in the present sample had a single component, it seems likely that genuine dS0 galaxies that have disk and bulge components are quite rare in the Virgo Cluster. The similarity in structural parameters of genuine dS0 galaxies in the Virgo Cluster with those of Magellanic-type galaxies implies that the progenitors of dwarf lenticular galaxies in the Virgo Cluster were most likely Magellanic-type galaxies if dS0s are harassed late-type spirals.

PCR-RFLP analysis was carried out to investigate the genotype of Melanocortin receptor 1 (MC1R) gene in Korean Brindle Cattle and Korean Cattle with dark muzzle, which are coat color and muzzle pigmentation variants of Korean Cattle, respectively. Allelic variants of MC1R in cattle were analyzed by digestion with BsrFⅠ, AciⅠ. Among six genotypes, $E^D/E^D,\;E^D/E^+,\;E^D/e,\;E^+/E^+,\;E^+$/e and e/e, detected in cattle, only two genotypes, $E^+/E^+\;and\;E^+$/e, were observed in Korean Brindle Cattle, probably reflecting the necessary of $E^+$ allele for the expression of black brindle coat color. As in Korean Cattle with light muzzle, the $E^+$/e and e/e genotypes were detected in Korean Cattle with dark muzzle. The $E^+$ and e alleles frequencies in two populations of Korean Cattle with dark muzzle and with light muzzle were 0.37, 0.63 and 0,11, 0.89, respectively. Although the frequency of $E^+$ allele in Korean Cattle with dark muzzle was higher than in Korean Cattle with light muzzle, the $E^+$ allele was not completely associated with dark muzzle pigmentation. The results of this experiment indicate that the difference of MC1R genotype and frequency may be useful for fixation of coat color in Korean Cattle as well as Korean Brindle Cattle.

Le but de notre recherche est $d^{\prime}{\acute{e}}clairer$ la nature du $d{\acute{e}}passement$ de soi aux actes humaines dnas le Thomisme. Dans le Thomisme la nature humaine qui a la raison et la $volont{\acute{e}}$ a une $intentionnalit{\acute{e}}$ ver la fin ultime. De sorte que les actes humaines qui $corr{\grave{e}}spondent$ cette nature humaine a un $caract{\grave{e}}re$ du $d{\acute{e}}passement$ de soi visant toujours plus que le $pr{\acute{e}}sent$. Le fondement de cet acte du $d{\acute{e}}passement$ de soi est $l^{\prime}{\hat{a}}me$ rationelle qui est la forme substantielle de l'homme et de soi subsistante. Chez st. Thomas ce $caract{\grave{e}}re$ du $d{\acute{e}}passement$ a trois ${\acute{e}}taps$ distinctes : (1)le $d{\acute{e}}passement$ dans l'ordre du $progr{\grave{e}}s$ naturel (2)le $d{\acute{e}}passement$ de soi dans l'ordre morale (3)le $d{\acute{e}}passement$ de soi dans l'ordre de la religion. Le $d{\acute{e}}passement$ dans l'ordre du $progr{\grave{e}}s$ naturel apparaît d'abord au $caract{\grave{e}}re$ de $l^{\prime}{\hat{a}}me$ rationelle. St. Thomas $d{\acute{e}}finit$ les vertus rationelles comme $^{\prime}pl{\acute{e}}nitude$ dans le $f{\acute{e}}blesse$, parce qu'il $consid{\grave{e}}re$ la vertu rationelle comme $finalit{\acute{e}}$ des $facult{\acute{e}}s$ du sens $ext{\acute{e}}rieur$. L'homme par le sens $ext{\acute{e}}rieur$ reçoit des $esp{\grave{e}}ces$ sensibles(especies sensibilis), et $poss{\grave{e}}de$ les images. Puis cette images sensible devenant la $r{\acute{e}}alit{\acute{e}}$ spirituelle sous forme du $m{\acute{e}}moire$ et du souvenir, devient aussi la partie de son existence. Donc chez st. Thomas la vertue rationnelle n'est pas simplement un $facult{\acute{e}}$ $sp{\acute{e}}culative$, mais elle est dans l'ordre du devenir et du $pl{\acute{e}}nitude$. A cette raison st. Thomas compare la raison(ratio) comme $g{\acute{e}}n{\acute{e}}ration$(generatio) et l'intelleigence(intellectus) comme ${\hat{e}}tre$(esse). C'est-${\grave{a}}$-dire la raison $d{\acute{e}}passe$ le sensible et l'intelligence $d{\acute{e}}passe$ la raison. Le $d{\acute{e}}passement$ de soi dans l'ordre morale $li{\acute{e}}$ au $progr{\grave{e}}s$ de la conscience. Chez st. Thomas la perception de l'objet $ext{\acute{e}}rieur$ ayant pour but d'avoir conscience de soi, se perfectionne ${\grave{a}}$ ceci. D'avoir conscience de soi signifie d'avoir $l^{\prime}identit{\acute{e}}$ de soi, et de-$l{\grave{a}}$ apparaît l'acte moral en tnat qu'acte $sp{\acute{e}}cifique$ humain. La raison pour laquelle la vie morale elle-$m{\hat{e}}me$ a un $caract{\grave{e}}$ du $d{\acute{e}}passement$, c'est que l'acte humaine qui corresfonde ${\grave{a}}$ $l^{\prime}identit{\acute{e}}$ du soi est une vie qui vise toujours plus que le $pr{\acute{e}}sent$ ou $l^{\prime}id{\acute{e}}al$. Quant au problem du $d{\acute{e}}passement$ dans l'ordre de la religion, chez st. Thomas en raison de $l^{\prime}affinit{\acute{e}}$ entre Dieu et l'homme, $o{\grave{u}}$ il y a des vertues infuses(virtutes infusas), il y a une sorte du $d{\acute{e}}passement$ religieux. Car ces vertues infuses signifie la communication entre Dieu(${\hat{E}}tre$ absolu) et l'homme(${\hat{e}}tre$ fine) et cela signifie le $d{\acute{e}}passement$ de l'humain vers le divin. Cette $id{\acute{e}}e$ thomiste permet de penser que $o{\grave{u}}$ il y a un $d{\acute{e}}passement$ de soi dans la vie religuse d'une personne, il y a une intervention $r{\acute{e}}elle$ de la providence divine. Cette $pens{\acute{e}}e$ thomiste sera alors un $caract{\grave{e}}$ $r{\acute{e}}aliste$ face ${\grave{a}}$ la $pens{\acute{e}}e$ $id{\acute{e}}aliste$ qui n'admette que le $d{\acute{e}}passement$ absolu comme $d{\acute{e}}passement$ religieux.

Ten multivoltine female parental lines were crossed with popular bivoltine male silkworm breed NB$_4$D$_2$. Three types of heterosis parameters viz., heterosis over mid-parental value (hybrid vigour), heterobeltiosis (useful heterosis) and standard heterosis (standard check) were estimated for 15 economically important quantitative traits. The interaction among the hybrids and parents indicated significant effect for maximum characters. The heterotic effect of new hybrid combination was compared with popular hybrids viz., Pure Mysore${\times}$NB$_4$D$_2$ and Nistari${\times}$NB$_4$D$_2$. Varied heterotic effect was observed for different traits for different hybrid combination. The results inferred that the crosses viz., BL$_{23}$${\times}$NB$_4$D$_2$ ranked top for 14 traits followed by Hosa Mysore${\times}$NB$_4$D$_2$ for 11 traits; PA$_{12}$${\times}$NB$_4$D$_2$ for 9 traits; BL$_{24}$${\times}$NB$_4$D$_2$ for 8 traits; Kolar Gold${\times}$NB$_4$D$_2$ for 7 traits; WAI$_1$${\times}$NB$_4$D$_2$ for 6 traits and MU$_{11}$${\times}$NB$_4$D$_2$ for 5 traits. Among these, the best hybrids Kolar Gold${\times}$NB$_4$D$_2$ and MU$_{11}$${\times}$NB$_4$D$_2$ were identified for longer filament length and fine denier. Similarly for higher cocoon yield and silk productivity BL$_{223}$${\times}$NB$_4$D$_2$ and BL$_{24}$${\times}$NB$_4$D$_2$ were found to be superior. These hybrid combinations are suitable for commercial exploitation at large scale.e.e.e.

Recent studies have reported that the distribution of HPV-16 sequence variation differs geographically, and more specifically that HPV-16 E6/E7 intratypic variants might carry a high risk for development of ICC (invasive cervical cancer) and CIN (cervical intraepithelial neoplasia) in a given population. To investigate the genetic diversities of HPV-16 E6/E7 oncogene by region, we collected nineteen HPV-16 isolates from sexually high-risk women in Busan, and analyzed the HPV-16 E6/E7 coding regions (nt 34 to 880) with HPV-16 E6/E7 specific PCR amplification. At the nucleotide levet eleven variants of the E6 genes and nine variants of the E7 genes were identified as follows: E6 T178G (n=l1), E6 T178A (n=l), E6 T350G (n=3), E6 A442C (n=2), E6 AI04T, E6 All1G, E6 C116T, E6 G145T, E6 T183G, E6 C335T, E6 G522C and E7 A647G (n=12), E7 A645C, E7 A777C, E7 G663A, E7 T732C, E7 T760C, E7 A775T, E7 T789C and E7 T795G, respectively. At the amino acid levet the isolated HPV-16 E6 and E7 genes showed eleven E6 variants: E6 D25E (n=12), E6 L83V (n=4), E6 E113D (n=2), E6 MIL, E6 Q3R, E6 P5S, E6 Q14H, E6 D25N, E6 127R, E6 H78Y, E6 C140S and three E7 variants: N29S (n=12), L28F, T72S. HPV16 E6 L83V, the dominant variant in the Caucasian population, showed relatively low frequencies in our study population. We elucidated that the dominant HPV-16 E6/E7 variants were HPV-16 E6 D25E (63.2%) and HPV-16 E7 N29S (63.2%), which were phylogenetically included in Asian lineage. Further study is needed to evaluate the risk of cervical cancer related HPV-16 E6/E7 intratypic variants in the Korean population.

Bacillus stearothemophilus isolated from soil was identified to express multiple extracellular xylanases. Two HindIII restriction fragments of 5.4 and 6.4 kb from B. stearothermophilus genomic DNA were cloned into pBR322 to obtain recombinant plasmids pMG0l and pMG02, respectively, which enabled E. coli HBlOl cells to produce $\beta$-D-xylosidase activity. By subcloning into pUC18 and Southern blotting, the loci of the $\beta$-D-xyiosidase genes were elucidated to be on non-homologous DNA fragments of 2.2 kb from pMGOl(pMG1) and 1.0 kb from pMG02(pMG2), respectively. The two enzymes produced in E. coli cleaved xylobiose, xylotriose, xylotetrose and xylotetrose to produce xylose as a major end product. The gene on pMG1, distinct from that on pMG2 was observed to encode a bifunctional protein that displayed both P-D-xylosidase (EC.3.2.1.37) and a-L-arabinofuranosidase activities (EC.3.2.1.55).

인터넷 기반의 B2B(Business to Business) 모델은 e비즈니스의 실현을 위한 기업의 정보시스템의 인프라와 같은 기반구조를 만들어가기 위한 기본 모델 역할을 하고 있다. 인터넷이 제공하는 표준 프로토콜을 기반으로 다양한 방식의 B2B 지원제품이 출시되고 있지만 그 어떤 제품도 기본적인 인터넷 프로토콜이 아닌 상위의 e비즈니스, 즉 다른 기업과의 협업이라는 관점에서 상호운용성을 보장하지 못하고 있으며 이 부분은 여전히 제품과 산업군에 매우 종속적이다. 이러한 단점을 해결하기 위하여 국제표준을 준수하며 BRB(Business- Registry- Business) 모델을 기반으로 한 글로벌 e비즈니스 솔루션인 XENI의 메세징 관련 제품과 레지스트리 관련 제품의 구현사례와 활용사례를 소개하고자 한다. 또한 국내의 취약한 SI 산업의 해결점이 될 수 있는 글로벌 솔루션 개발이라는 측면에서 향후 보완되어야 할 부분들을 제안한다.

Ethanolic extracts of twenty-one plant species were tested in vitro for their fungitoxic properties against leaf spot causing pathogen of mulberry Myrothecium roridum by poisoned food technique. Ethanolic extracts of twenty-plant spp. reduced mycelial growth of M. roridum significantly except E. pulcherrima. Highest inhibition of M. roridum colony growth observed in 10% extracts of E. citriodora (49.45%) followed by D. metel (39.45%), Chromolaena odoratum (25.56%) and A. sativum (25.00%). Among the concentration tested, 10% concentration was found significantly higher effective on reducing colony growth followed by 5 and 2.5%. Aqueous extract fresh leaves/bulb of seven short-listed plant spp. (inhibition>15% in ethanolic extracts) revealed that D. metel inhibited (23.43%) followed by E. citriodora (14.66%), C. odoratum (13.53%). On dry leaf extracts D. metel was found more effective than E. citriodora. The results indicated that D. metel, E. citriodora, C. odoratum and A. sativum having high fungitoxicity against M. roridum and ethanolic extract found more effective than aqueous extract.
