Let D be an integrally closed domain with quotient field K, * be a star operation on D, X, Y be indeterminates over D, $N_*\;=\;\{f\;{\in}\;D[X]|\;(c_D(f))^*\;=\;D\}$ and $R\;=\;D[X]_{N_*}$. Let b be the b-operation on R, and let $*_c$ be the star operation on D defined by $I^{*_c}\;=\;(ID[X]_{N_*})^b\;{\cap}\;K$. Finally, let Kr(R, b) (resp., Kr(D, $*_c$)) be the Kronecker function ring of R (resp., D) with respect to Y (resp., X, Y). In this paper, we show that Kr(R, b) $\subseteq$ Kr(D, $*_c$) and Kr(R, b) is a kfr with respect to K(Y) and X in the notion of [2]. We also prove that Kr(R, b) = Kr(D, $*_c$) if and only if D is a $P{\ast}MD$. As a corollary, we have that if D is not a $P{\ast}MD$, then Kr(R, b) is an example of a kfr with respect to K(Y) and X but not a Kronecker function ring with respect to K(Y) and X.

A display device combining plasma display panel (PDP) and field emission display (FED) is proposed to achieve high luminous efficiency. The device can avoid the main energy loss channels of both PDP (ion loss) and FED (low CL efficiency). $2{\sim}6$”-diagonal test panels with carbon nano-tube (CNT) electron emitter and Xenon ambient gas showed the luminous efficiency of 4.14lm/W and brightness of $263cd/m^2$ at 35V (1kHz, 1% duty), indicating that it is a good candidate for the low voltage driven, highly efficient next generation display.

최근 3D 입체 영화 및 3D 방송 기술의 개발과 더불어, 사용자의 몰입감을 극대화하기 위하여, 3D 입체영상과 사용자의 인터랙션 효과를 융합하는 3D Interaction 기술이 개발되고 있다. 본 논문에서는 3D 디스플레이에서의 시각안전영역을 고려한 3D 사용자 인터페이스의 구현 방법에 대해서 소개한다. 사용자의 입력에 따라 객체의 변이 정보를 계산하고, 변이 정보가 사람의 시각안정영역 내에서 존재하도록 적응적으로 깊이를 조절하여, 사용자의 시각적 편안함과 3D 객체에 대한 조절 기능을 제공할 수 있다. 무안경 3D 디스플레이 상에서의 구현 결과를 통해 제안하는 기술의 효율성을 보여준다.

최근, 다수의 3D 콘텐츠가 개발되고 있으며 이러한 3D 콘텐츠는 스테레오 카메라를 이용하여 촬영되고 있다. 그러나 대부분의 3D 콘텐츠는 제작자의 개인적인 경험에 바탕을 두고 제작되고 있어, 일괄적인 기준이 모호한 상황이다. 이에 본 논문에서는 제공된 정보로부터 정확한 3D 정보들을 계산해주는 3D 계산기를 제안한다. 제안된 3D 계산기는 제작자의 선택을 돕고자, 주어진 정보로부터 정확한 기기의 위치, 받침대의 위치, 시차, 카메라와 렌즈의 떨어진 거리등을 계산해준다. 따라서, 제안된 3D 계산기는 촬영 대상 물체가 실제 영화관이나 3D Display 상에서 어떻게 보여지는지를 미리 계산하여 보여줌으로써, 3D 콘텐츠를 제작함에 있어 제작시간을 줄이고 제작자의 의도를 정확하게 반영할 수 있도록 도와준다. 제안된 3D 계산기는 windows OS, iOS, 그리고 android OS 등 다수의 OS에서 사용 가능하도록 다수의 OS상에서 포팅이 되어 있다.

This paper presents an automatic pose-normalized 3D face data acquisition method using 2D and 3D information. We propose an automatic pose-normalized 3D face acquisition method that accomplishes 3D face modeling and 3D face pose-normalization at once. The proposed method uses 2D information with AAM (Active Appearance Model) and 3D information with 3D normal vector. The 3D face modeling system consists of 2 cameras and 1 projector. In order to verify proposed pose-normalized 3D modeling method, we made an experiment for 2.5D face recognition. The experimental result shows that proposed method is robust against pose variation.

To investigate the genetic variation of high-and low-molecular-weight glutenin subunits (BMW-GS and LMW-GS), granule-bound starch synthase I (GBSSI) and puroindoline in 24 Korean wheat cultivars. At the BMW-GS compositions, three Glu-A1 alleles, five Glu-B1 alleles and three Glu-D1 alleles were identified. The high frequency of alleles at each locus was Glu-A1c allele (15 cultivars), Glu-B1b allele (16 cultivars) and Glu-D1f allele (16 cultivars). Four alleles were identified at the Glu-A3 and Glu-B3 loci and three at Glu-D3 locus and Glu-A3d, Glu-B3d and Glu-D3a were mainly found at each Glu-3 locus. Glu-A3d, Glu-B3d, Glu-D3b or c (4 cultivars, respectively) and Glu-A3d, Glu-B3d, Glu-D3a and Glu-A3c, Glu-B3d or h, Glu-D3a (3 cultivar, respectively) were predominantly found in Korean wheats. At the GBSS compositions, 2 waxy wheat cultivars, Shinmichal and Shinmichal1, showed null alleles on the Wx loci and other cultivars were wild type in GBSS compositions. At the puroindoline gene compositions, Korean wheat cultivars carried 3 genotypes, which 10 cultivars (41.7%) were Pina-D1a and Pinb-D1a, 11 cultivars (45.8%) had Pina-D1a and Pinb-D1b and 3 cultivars (12.5%) carried Pina-D1b and Pinb-D1a. These genetic variations could present the information to improve flour and end-use quality in Korean wheat breeding programs.
