Scopolia parviflora Nakai, a rare and endangered species, is the sole plant producing tropane alkaloids (TA) among the Korean native species. In order to enhance TA productivity the SP72 root line was selected by screening 100 of root line, and the optimal culture media for root growth and TA production were investigated with the SP72 roots. Based on the several media, SH and 2B5 medium were determined as growth medium and White and NN medium as production medium. Among the four combinations of two-stage culture, 2BN (2B5 as growth medium plus NN as production medium) showed more enhanced root growth and TA production as compared with production media of White and NN medium and growth media of SH and 2B5 medium, respectively. However, bubble column bioreactor (BCB) cultures applying two-stage culture did not reveal the effective results despite of the each successful operation of two-stage culture in conical flasks and BCB cultures.

Cellulase의 합성 및 그의 조절기작을 밝히기 위한 기초연구로서 Aspergillus nidulans FGSC 168로 부터 CMC 배지에서 자라지 못하는 돌연변이주인 TCD27, NCN2, ACN 14, ACN3를 얻어내어 이들의 성질을 분석하였다. 이들 4가지 돌연변이주는 모두 inducer를 세포내로 수송하는 permease를 만들어 내는 유전자에는 아무 결함이 없었다. 이들 중 ACN3는 cellulase의 합성 및 그의 조절 기작과는 직접 관련이 없는 돌연변이주로 추정되나, TCD 27과 NCN2는 조절 유전자에 돌연변이가 일어났을 가능성이 있고, ACN 14는 구조 유전자 돌연변이주일 것으로 추정되었다.

We present a comprehensive derivation of the transport of holes involving an interacting two-valence-band system in terms of a generalized relaxation time approach. We sole a pair of semiclassical Boltzmann equations in a general way first, and then employ the conventional relaxation time concept to simplify the results. For polar optical phonon scattering, we develop a simple method th compensate for the inherent deficiencies in the relaxation time concept and apply it to calculate effective relaxation times separately for each band. Also, formulas for scattering rates and momentum relaxation times for the two-band model are presented for all the major scattering mechanisms for p-type GaAs for simple, practical mobility calculations. Finally, in the newly proposed theoretical frame-work, first-principles calculations for the Hall mobility and Hall factor of p-type GaAs at room temperature are carried out with no adjustable parameters in order to obtain a direct comparison between the theory and recent available experimental results, which would stimulate further analysis toward better understanding of the complex transport properties of the valence band. The calculated Hall mobilities show a general agreement with our experimental data for carbon doped p-GaAs samples in a range of degenerate hole densities. The calculated Hall factors show $r_H$=1.25~1.75 over all hole densities($2{\times}10^{17}{\sim}1{\times}10^{20}cm^{-3}$ considered in the calculations.

It is necessary to develop the simulator for the test of stability and torque before the walking experiment of biped robot, because a robot may be damaged in an actual experiment. This thesis deals with the development of three-dimensional simulator for improving efficiency and safety during development and experimentation. The simulator is composed of three parts-solving dynamics, rendering pictures and communicating with the robot. In the first part, the D-H parameter and parameter of links can be loaded from the file and edited in the program. The results are obtained by using the Newton-Euler method and are stored in the file. Through the above process, the proper length of link and driving force can be found by using simulator before designing the robot. The second part is organized so that the user can easily see a specific value or a portion he wants by setting viewing parameters interactively. A robot is also shown as a shaded rendering picture in this part. In the last part, the simulator sends each desired angle of joints to the robot controller and each real angle of joints is taken from the controller and passed to the second part. The safety of the experiment is improved by driving the robot after checking whether the robot can be actuatable or not and whether the ZMP is located within the sole of the foot or not for a specific gait. The state of the robot can be easily grasped by showing the shaded rendering picture which displays the position of the ZMP, the driving force and the shape of robot.

Crystallization of SAPO-5 and SAPO-34 molecular sieves with microwave and conventional electric heating of the same gel has been investigated in an alkaline condition using N,N,N’N’tetraethylethylenediamine as a template molecule. SAPO-5 structure can be selectively prepared with microwave heating because of the fast crystallization of the technique. On the other hand, SAPO-34 is the sole product with usual conventional electric heating because SAPO-5 can be gradually transformed into SAPO-34 structure with an increase in crystallization time. This phase selectivity is probably because of the relative stability of the two phases at the reaction conditions (kinetic effect). Crystallization with microwave heating can be suggested as a phase selective synthesis method for relatively unstable materials because of fast crystallization.

Charter flight in international air law has, from very beginning, not precisely defined by the International Civil Aviation Organization (lCAO) since 1947 when it came into being. By practice, the operation of charter traffic is, in its very beginning, the subject to the regulations of national rules and bilateral charter agreements (charter annex clause) within the framework of normal bilateral agreement of international air services. Taiwan had signed a series of bilateral air service agreement under the name of the Government of the Republic of China when Taiwan was recognized by the United Nations and major members of international community as the sole legal government representing China before 1971, but that situation was changed since then. Taiwan has only maintained diplomatic relations with 25 States, but maintained semi-official relations with major powers of the world. The former agreements were signed within the framework of the Vienna Convention on the Law of Treaties of 1969 while the latter agreements were signed within the framework of administrative and civil law of two countries which were not in the form of bilateral treaty signed by two sovereign States in its proper sense of international law. The legal regime of charter flights between Taiwan and Mainland China is regulated by special arrangements negotiated by delegated airlines and airlines association or private law institutions.

The strain of Serratia marcescens QM B1466 produces selectively large amount of chitinolytic enzymes (about 1mg/L medium). Enzymatic hydrolysis of chitin to N-acetyl-${\beta}$-D-glucosamine (NAG) was performed with a system consisting of two hydrolases (chitinase and chitobiase) produced by optimization of a microbial host consuming chitin particles. For the development of Large-scale biological process for the production of NAG from chitinaceous waste, the selection and optimization of a microbial host, particle size of crab/shrimp chitin sources and initial induction time using chitin as a sole carbon source on chitinase/chitobiase production and NAG production were examined. Crab-shell chitin(1.5%) treated by dilute acid and , ball-milled with a normal diameter less than 250m gave the highest chitinase activity over a 7 days culture. Crude chitinase/ chitobiase solution obtained in a 10 L fed-batch fermentation showed a maximum activities of 23.6 U/mL and 5.1 U/mL, respectively with a feeding time of 3 hrs, near pH 8.5 at 30$^{\circ}C$.

Of the 500 Actinomycetes isolates obtained from soil, one isolate grown on maltose as the sole carbon source produced compound BHK-P19, which inhibited the growth of multiple drug resistant P. aeruginosa 0245. Ultraviolet radiation mutagenesis curtailed production of BHK-P19. Mutation of the BHK-P19 producer using N-methyl-N'-nitro-N-nitroso-guanidine obviated the antibacterial activity to P. aeruginosa 0245, but not towards P. aeruginosa 0225. The mixing of BHK-P19 and BHK-S5 culture extracts inhibited P. aeruginosa 0254, 0225 and 1113. The combined application of BHK-P19 culture extract and Schizandra chinensis Baillon extract inhibited P. aeruginosa 0254, 0225, 0826, 1113, 1378, 1731 and 2492. Use of various concentrations of BHK-P19 culture extract and ampicillin markedly increased antibacterial activity against multi-drug resistant P. aeruginose 1113.

한천분해 세균은 제주 연안의 해수로부터 분리되어졌다. 균주는 Gram 음성 간균이며, 절대 호기성 세균이다. 균주는 agarase를 생성하여 한천을 분해하는 것으로 관찰되었다. 균주의 생화학적 특성과 16S rRNA 유전자 염기서열 분석한 결과 Agarivorans속으로 동정 되었다. 그래서 Agarivorans sp. JA1이라 명명하였다. agarase의 최적 생산을 위한 agar농도는 0.5%이며, pH, 온도와 NaCl 농도는 각각 pH 7, $25^{\circ}C$ $^{\sim}$ $30^{\circ}C$와 2%였다. 유기태과 무기태는 각각 yeast extract와 $NaNO_3$를 첨가 할 경우 agarase 생성이 가장 좋은 것으로 사료되었다. Agarase의 최적 생산 활성 측정은 DNS법(3,5-dinitrosalicyclic acid procedure)을 이용하여 환원당 값을 산출하였고, 50000(U/L)이상 나왔다.
