위도상사화(Lycoris uydoensis M. Kim)의 효율적인 기내 급속 대량 증식체계를 확립시키고자 잎과 인편을 배양하였다. 5℃에서 60일간 저온 처리한 모구를 구고를 중심으로 상부, 중부 및 하부로 구분하여 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA, 0.5 mg·L-1 NAA와 1.0 mg·L-1 BA 또는 3.0mg·L-1 IBA와 3.0 mg·L-1 BA 혼용처리된 MS 배지에 배양한 결과 식물생장조절물질과는 관계없이 디스크가 부착된 인편의 하부가 캘러스 및 자구 형성에 가장 효과적인 부위였다. 캘러스는 잎절편이나 인편조직에서 쉽게 형성되었으나 소자구 및 신초는 인편에서만 형성되어 기내번식에 적합한 절편체는 인편이었다. 자구 형성 및 신초분화는 배지내 첨가된 식물생장조절물질에 따라 치상체에서 직접 자구를 형성하거나 캘러스를 통해 식물체로 분화되는 2가지 경로로 형성되었는데 디스크가 부착된 인편을 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA, 0.5 mg·L-1 NAA와 1.0 mg·L-1 BA 또는 3.0 mg·L-1 IBA와 3.0 mg·L-1 BA 혼용처리된 MS 배지에 배양하여 30일 이내에 60%-100%까지 유도하였다. 다량의 자구형성 및 유지는 MS배지에 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA가 혼용되거나 또는 3.0 mg·L-1 IBA와 3.0mg·L-1 BA 혼용처리 되었을 때 0.5 mg·L-1 NAA와 1.0mg·L-1 BA 혼용처리 되었을 때 보다 효과적이었다. 6% sucrose는 자구형성 및 비대를 촉진시켰으며 특히 3.0 mg·L-1 IBA와 3.0 mg·L-1 BA 혼용처리배지에 6% sucrose를 첨가시키므로 0.1 mg·L-1 2,4-D와 1.0 mg·L-1 BA가 혼용 배지보다 구의 비대가 1-2배 증가하였다. 인편유래 캘러스로부터 기관분화 또는 인편에서 직접 분화된 자구에서 성공적으로 식물체가 재분화되었다. This study was conducted to establish an effective in vitro mass propagation system using leaf and bulb scale explant sources of Lycoris uydoensis M. Kim. For the bulb scale culture, the bulbs treated at 5℃ for 60 days were dissected into three parts according to bulb height (upper, middle, and bottom), and allowed for a culture on the MS medium with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA, 0.5 mg ? L-1 NAA plus 1.0 mg ? L-1 BA, and 3.0 mg ? L-1 IBA plus 3.0 mg ? L-1 BA. Regardless of plant hormone treatments, the bottom part of the bulb including the disk proved to be most effective in forming the callus and bulblets. Callus was readily produced on the young leaf segment and bulb scale tissues, whereas, bulblets and shoots were formed only on bulb scale explants. Bulb scales with disk appeared to the best optimal explant for in vitro propagation. Two distinct pathways, either organogenesis through callus or direct bulblet formation, could be recognized in bulb scale culture. Bulblet formation and shoot organogenesis from the bulb scales with disk were effectively induced up to the 60%~100% on the MS medium supplemented with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA, 0.5 mg ? L-1 NAA plus 1.0 mg ? L-1 BA, and 3.0 mg ? L-1 IBA와 3.0 mg ? L-1 BA within 30 days of culture. On MS media supplemented with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA or 3.0 mg ? L-1 IBA와 3.0 mg ? L-1 BA were more effective than 0.5 mg ? L-1 NAA plus 1.0 mg ? L-1 BA for induced and maintained a large number of bulblets. Six percent of sucrose enhanced bulblet formation and expanded the bulblets. Especially, adding 6% of sucrose on MS media supplemented with 3.0 mg ? L-1 IBA와 3.0 mg ? L-1 BA was one or two times of bulblets expanted than on MS mediun with 0.1 mg ? L-1 2,4-D plus 1.0 mg ? L-1 BA plus 6% of sucrose. Plantlet regeneration was successfully achieved from bulb scale-derived callus, via shoot bud induction or direct bulblet formation.

Acidity and saccharification power of their koji were ranged in 5.0~6.8 and 128sp~241sp. Nine fungi which were showed good quality and sensory evaluation were identified by analysis of their nucleotide sequences with PCR-amplified 18S rDNA internal transcribed spacer-1(ITS-1) and ITS-4 genes. Among them, six strains were identified as Aspergillus oryzae and the other strains were identified as Mycocladus corymbiferus, Rhizopus oryzae, Lichtheimia corymbifera.

동중 유사 상태로의 파이온 단일전하교환 반응A(π??,π??)A'(lAS)에서 0??~미분 산란 단면적을 30~70Mev 에너지 영역에 걸쳐 계산하였다. 표적으로는 Li?과 C? 핵종을 선택하였으며, 반응이론은 distorted-wave impulse approximation에 의해 기술하였다. 계산에 이용한 광학적포텐셜에서 S-wave 및 P-wave의 효과를 동시에 고려했으며, Pauli-blocking효과도 고려하였다. 0?-미분 산란단면저의 에너지 의존성으로부터 40~50Mev 에너지 영역에서 최소값을 얻었으며,이것은 자유파이온-핵자 단일전하교환 산란단면적의 에너지 의존성에서 볼 수 있는 S-파 와 P-파의 간섭효과를 잘 나타내고 있다. The zero-degree differential cross section calculations for the ?Li(π??,π??)Be?? and ??C(π??,π??)N??reactions to isobaric analog state(IAS) are presented for the energy range between 30∼70 Mev, using the distorted-wave impulse approximation(DWIA)in an eikonal framework. The optical potentials are considered using both S-wave and P-wave, and the Pauli-blocking effect is considered. A deep minimum is found near 40∼50 Mev in the excitation function. It reflects the analogous minima of the interference between S-wave and P-wave which was seen in the free pion-nucleoncleon single charge exchange(SCX)cross section of Rowe et al..

Detailed information about the structural nature of three-coordinate borons in ${\beta}-BaB_2O_4$ is obtained through $^{11}B$ MAS NMR and $^{11}B$ single-crystal NMR. The three-coordinate $BO_3$ of the two borons B(1) and B(2) in ${\beta}-BaB_2O_4$ were distinguished. The spin-lattice relaxation time in the laboratory frame $T_1$ for B(1) and B(2) slowly decreases with increasing temperature, whereas the spin-lattice relaxation time in the rotating frame $T_{1{\rho}}$ for B(1) and B(2), which differs from $T_1$, is nearly constant. The B(1) and B(2) of the two types were distinguished by $^{11}B$ MAS NMR and $^{11}B$ single-crystal NMR.

The spin-lattice relaxation times, $T_1$, and spin-spin relaxation times, $T_2$, of the $^{27}Al$ and $^{87}Rb$ nuclei in $RbAl(CrO_4)_2{\cdot}2H_2O$ crystals were investigated. The presence of only one resonance line for the $^{27}Al$ nuclei indicates that the results in a dynamical averaging of the crystal electric field that produces a cubic symmetry field. The changes in the temperature dependence of $T_1$ are related to variations in the symmetry of the octahedra of water molecules surrounding $Al^+$ and $Rb^+$. The $T_1$ values for the $^{27}Al$ and $^{87}Rb$ nuclei are different due to differences in the local environments of these ions. We also compared these $^{27}Al$ and $^{87}Rb$ NMR results with those obtained for $RbAl(CrO_4)_2{\cdot}2H_2O$ crystals. The relaxation mechanisms of $RbAl(XO_4)_2{\cdot}nH_2O$ (X=Cr and S) crystals are characterized by completely different NMR behaviors.

The structural characteristics of 4-coordinate $BO_4$ [B(1)] and 3-coordinate $BO_3$ [B(2)] groups in $BiB_3O_6$ were studied by $^{11}B$ magic angle spinning (MAS) and single-crystal nuclear magnetic resonance (NMR) spectroscopy. The spin-lattice relaxation time in the laboratory frame, $T_1$, for $^{11}B$ decreased slowly with increasing temperature, whereas the spin-lattice relaxation times in the rotating frame, $T_{1{\rho}}$, for B(1) and B(2), which differed from $T_1$, were nearly constant. Further, $T_{1{\rho}}$ for B(1) and B(2) showed very similar trends, although the $T_{1{\rho}}$ value of B(2) was shorter than that of B(1). The 3-coordinate $BO_3$ and 4-coordinate $BO_4$ were distinguished by $^{11}B$ MAS NMR spectrum and $T_{1{\rho}}$.
