We have previously produced transgenic (TG) mice expressing the human lactoferrin (hLF), interleukin-10 (hIL-10), and thrombopoietin (hTPO) proteins in the milk. In this study, we examined whether simple crossbreeding between two kids of a single transgenic mouse can produce double transgenics co-expressing two human proteins.. The hLF male, and the hIL-10 male were crossbred with the hIL-10 and hTPO females, and the hTPO female, respectively. PCR analysis for genotyping showed 32%, 23% and 24% double transgenic rates for hLF/hIL-10, hLF/hTPO, and hIL-10/hTPO transgenes, respectively. We analyzed the expression levels of the human proteins from double transgenic mice and compared those with their single transgenic siblings. All double transgenic co-expressed two human proteins at comparable levels to singles', unless hTPO was not co-expressed: for hLF, 1.1 mg/ml in hLF/hIL-10, whereas 0.5 mg/ml in hLF/hTPO; for hIL-10, 4.1 mg/ml in hIL-10/hLF, whereas 1.4 mg/ml in hIL-10/hTPO. Ihe downregulation of hTPO to half level of singles' was observed in double transgenic mice. The possible reason why hTPO co-expressed might lead to down-regulation of another human protein was discussed. These results suggested that double transgenic generated by crossbreeding between two singles' could be useful system for bioreactor.

본 논문에서는 입력에 제한이 있는 시간지연 비선형 시스템에 대한 퍼지 $H_2/H_{\infty}$ 제어기 설계 방법을 제시한다. 포화입력을 갖는 시간지연 비선형 시스템을 시간지연과 포화입력을 갖는 Takagi-Sugeno 퍼지 모델로 표현하고 병렬분산보상(PDC)의 개념을 이용하여 제어기를 설계한다. Lyapunov 함수를 이용하여 시간지연과 포화입력을 갖는 $H_2/H_{\infty}$ 퍼지모델에 대한 폐루프 시스템의 안정성 조건과 LQ 성능을 최소화하는 조건을 유도하고, 퍼지 $H_2/H_{\infty}$ 제어기가 존재할 충분조건을 선형행렬부등식(LMI: liner matrix inequality)을 이용하여 구한다. 제어기는 선형행렬부등식의 해를 구하므로써 바로 구할 수 있으며, 설계된 퍼지 $H_2/H_{\infty}$ 제어기는 $H_{\infty}$ 노옴 한계값을 만족하면서 LQ성능의 상한값을 최소화한다. 마지막으로 포화압력으로 포화압력을 가지는 시간지연 비선형 시스템에 대해 퍼지 $H_2/H_{\infty}$ 제어기 설계 사례를 보인다.

Let R be a ring, and ${\alpha}$ be an endomorphism of R. An additive mapping H : R ${\rightarrow}$ R is called a left ${\alpha}$-multiplier (centralizer) if H(xy) = H(x)${\alpha}$(y) holds for all x,y $\in$ R. In this paper, we shall investigate the commutativity of prime and semiprime rings admitting left ${\alpha}$-multiplier satisfying any one of the properties: (i) H([x,y])-[x,y] = 0, (ii) H([x,y])+[x,y] = 0, (iii) $H(x{\circ}y)-x{\circ}y=0$, (iv) $H(x{\circ}y)+x{\circ}y=0$, (v) H(xy) = xy, (vi) H(xy) = yx, (vii) $H(x^2)=x^2$, (viii) $H(x^2)=-x^2$ for all x, y in some appropriate subset of R.

It is shown that every almost linear mapping h : $A{\rightarrow}B$ of a unital PoissonC*-algebra A to a unital Poisson C*-algebra B is a Poisson C*-algebra homomorph when $h(2^nuy)\;=\;h(2^nu)h(y)$ or $h(3^nuy)\;=\;h(3^nu)h(y)$ for all $y\;\in\;A$, all unitary elements $u\;\in\;A$ and n = 0, 1, 2,$\codts$, and that every almost linear almost multiplicative mapping h : $A{\rightarrow}B$ is a Poisson C*-algebra homomorphism when h(2x) = 2h(x) or h(3x) = 3h(x for all $x\;\in\;A$. Here the numbers 2, 3 depend on the functional equations given in the almost linear mappings or in the almost linear almost multiplicative mappings. We prove the Cauchy-Rassias stability of Poisson C*-algebra homomorphisms in unital Poisson C*-algebras, and of homomorphisms in Poisson Banach modules over a unital Poisson C*-algebra.

This study is to present a female high school summer blouse with high movement functionality and satisfying appearance. For the experimental research 6 subjects with closest average body shapes and their body surface was measured at beginning and after selecting a representative movement the tested uniform was worn and the appearance and movement functionality was evaluated. The results of this research are as follows. In the research with the aims to improve the sleeve designed the height in 3 types as A.H/4+3, A.H/4+2, A.H/4+1 and their evaluation showed that in the order of best appearance was A.H/4+2, A.H/4+1, A.H/4+3. In the order of best comfort was A.H/4+2, A.H/4+3, A.H/4+1 and the best order for movement functionality was A.H/4+1, A.H/4+2, A.H/4+3. Additional height types designed produced from elastic materials were A.H/4+3, A.H/4+2, A.H/4+1 and the resulting order of appearance was A.H/4+3, A.H/4+2, A.H/4+1, order of comfort was A.H/4+3, A.H/4+2, A.H/4+1 and the order of movement functionality was A.H/4+1, A.H/4+2, A.H/4+3. Integrating these results shows that in using the same concurrent materials, the experiment pattern of setting the sleeve height as A.H/4+2 was the best while in using elastic materials, the experiment pattern of setting the sleeve height as A.H/4+3 was the best.

Pattern grading is a technique used to increase or decrease the size of a garment pattern according to the measurements in a given size chart. The original pattern is graded and laid out for cutting before mass production. This study tried to classify body types for pattern grading of jacket by applying a concept of "drop"defined as the difference between chest girth and waist girth and the difference between hip girth and waist girth for pants. Data were collected through the stratified sampling method. 138 subjects were selected out of 1,290 subjects of our sample population. Findings were as follows : 1) For pattern grading of jacket, the cell with the chest girth of 96cm and the waist girth of 87cm had the highest frequency rate and body type was 87H type and the coverage of this type was 9.52%. Then, the size specification 87-96 was the center of distribution. H type had seven ones such as 72H, 75H, 78H, 81H, 84H. 87H and 90H. H type had 33 observations and frequency ratio of 26.19%. Same types could be graded up and down from the reference size for the age group. And this reference size became to the starting point for developing the grading system. 2) For pattern grading of pants, fatty types, H10 type had six ones such as 80H10. 82H10, 84H10, 86H10, 88H10 and 90H10. H10 type had 28 observations and frequency ratio of 20.29%. H6 type had 6 ones such as 84H6, 86H6, 88H6, 90H6. 92H6 and 94H6. H6 type had 27 observations and frequency ratio of 19.57%. If lower body types were classified as same ones, these types could be graded up and down proportionately.

수화물 결정에 있어서 $H_2O$ 분자의 외부 각 운동을 조사하고저 NaBr-2$H_2O$ 및 BaCl$_2$-2$H_2O$ 분말시료에 대한 중성자비탄성산란실험을 수행하였으며, 관측된 진동수를 모두 이 외부 각 운동에 의한 것으로 보고 다중 및 다준위산란효과를 제거하므로서 평균진동수 분포함수를 구하였다. FG 행열법에 의해서 계산된 진동수의 이론 값들은 모두 복합 mode에 의한 것이였으며 따라서 그 중 포텔샬.에너지분포가 큰 mode로서 관측치에 대한 assignment를 하였다. 소수결합력은 Lippincott-Schroeder 포텐샬함수에서 추산하였으며, 절선형 및 분기형수소결합에 대한 이 함수의 유용성을 $H_2O$ 외부 각 운동 포텐샬함수 모양에 의거하여 검토하였다. 수소결합력의 성질에 대하여 더욱 자세한 자료를 얻기 위해서는 진동수 계산에 H…Y 신축상호작용 운만 아니라 O-H…Y 변각상호작용의 도입이 필요함을 논의하였고 또 $H_2O$ 외부 각 운동에 인어서 mode의 순수성 및 대칭성을 군론을 작용한 방법에 의거하여 논의하였다.

Five species of Hypoglossum from the coasts of Korea were described. They were distinguished each other by vegetative morphology as well as reproductive structures. H. barbatum Okamura and H. simulans Wynne, Price et Ballantine were similar in their subalternate branchings but they were clearly different by developmental mode of 3rd-order cell rows. H. simulans is distinguished from H. barbatum as well as from the other three species in that only innermost cells of 2nd-order rows cut off 3rd-order cell rows. H. geminatum Okamura and H. caloglossoides Wynne et Kraft are oppositely branched but the latter is characterized by regular constrictions at branching points. H. minimum Yamada developed simple blades. Among them, H. simulans, H. caloglossoides, and H. minimum are newly recorded from Korean waters.

Two new marine sponges in the family Chalinidae, Haliclona (Haliclona) uljinensis n. sp. and Haliclona (Reniera) hongdoensis n. sp., are collected from Uljin and Hongdo Island, Korea during 2004-2007. H. (H.) uljinensis n. sp. is closely related to H. (H.) oculata in type of spicules. However, ectosomal skeleton of H. (H.) uljinensis n. sp. is reticulated and isodictyal reticulated type but H. (H.) oculata has not any dermal specialization in skeleton. The growth form of H. (H.) uljinensis n. sp. is thin encrusting with numerous cylindrical tubes on the surface but H. (H.) oculata is solid branch form. Haliclona (R.) hongdoensis n. sp. is closely related to H. (R.) aquaeductus in skeletal structure and growth form. However, oxeas of H. (R.) hongdoensis n. sp. are larger than H. (R.) aquaeductus's.
