Some after-dinner thoughts on the giants of infrared space astronomy. I here describe important events in infrared astronomy starting from 1964 when I started working on my PhD. Here I describe how I became involved in IRAS, Infrared Space Observatrory (ISO), Herschel, Spitzer and AKARI, together with important events that led to these great missions.

Anthers of two hot pepper cultivars, Milyang-jare and Geryongsan-jare, were cultured on MS medium containing 0.1 mg/L 2,4-D and 0.1 mg/L kinetin. The influence of pretreatment at 4$^{\circ}C$ and 32$^{\circ}C$ on induction of microspore embryo was investigated. Milyang-jare was superior to the Geryongsan-jare in microspore embryo induction. The 32$^{\circ}C$ pretreatment increased embryo induction compared to the 4$^{\circ}C$ pretreatment while the 4$^{\circ}C$ pretreatment stimulated callus induction. Microspore embryos were regenerated to plantlets in the same medium or hormone free medium at 32$^{\circ}C$ treatment but most embryos failed to develop directly into plantlets at 4$^{\circ}C$ treatment. The optimal period of the 32$^{\circ}C$ pretreatment was 3 days in Milyang-jare and 6 days in Geryongsan-jare. The 32$^{\circ}C$ pretreatment was essential for induction and growth of microspore embryo in pepper.

In this paper, an analysis of the optimized 3D depth of integral imaging is proposed. We achieve this by calculating the amount of image distortion and considering the threshold of recognition in the human visual system. Experimental results are also provided to test the theory.

Digital holography is a computational operation and photo-electronic technology that enables calculating, encoding, and reconstructing a 3D scene based on the interference of a coherent light-wave field. The spatial light modulator in a holographic 3D display decodes a computer-generated hologram to optically regenerate a 3D scene in various depths, thus facilitating to match convergence and accommodation of the human eyes. This paper introduces recent technologies related with the content for digital holography called an ultimate 3D display.

Let C be a smooth complex algebraic curve of genus g. For a divisor D on C, dim D means the dimension of the complete linear series $\mid$D$\mid$ containing D, which is the same as the projective dimension of the vector space of meromorphic functions f on C with divisor of poles $(f)_\infty \leq D$.

Let A be a (complex) Banach algebra. The object of the this paper shall be remove the continuity of the derivation in the recently theorems. We prove that every derivation D on A satisfying [D(a), a] ${\in}$ Prad(A) for all a ${\in}$ A maps into the radical of A. Also if ${\alpha}D^3+D^2$ is a derivation for some ${\alpha}{\in}C$ and all minimal prime ideals are closed, then D maps into its radical.

렌즈어레이 기반의 3D 집적 영상 디스플레이 기술은 비교적 간단한 시스템 구조에서 무안경 방식의 완전시차(full parallax)를 가지는 3D 영상 표시가 가능하기 때문에 차세대 디스플레이 기술 중에 하나로 여겨지고 있다. 본 고에서는 이러한 렌즈어레이 기반의 3D 집적 영상 디스플레이에 대해서 소개하고, 최근에 성능 향상을 위하여 개발이 진행 중인 시간다중화 3D 집적 영상 디스플레이 기술과 콘텐츠 생성 기술에 대해서 설명한다.
