Ginseng(Panax ginseng C.A. Meyer) is a perennial herbaceous plant which grows very slowly. It takes about 3 to 4 years from seeding to collecting the ripe seeds and the ginseng propagation is very difficult. and so, it is very difficult to breed ginseng plant. Ginseng tissue culture was started from at 1960, and ginseng commercial product by in vitro callus culture was saled, however upto now, regenerants were not planted to soil normally. Recently, plant genetic engineering to produce transgenic plants by introducing useful genes has been advanced greatly. In a present paper, transformation of ginseng plants was achieved by co-cultivation with Agrobacterium harboring the binary vector coding Proteinase-II gene, which confer resistant or tolerant to insect pests, The binary vector for transformation was constructed with disarmed Ti-plasmid and with double 35S promoter. The NPT II gene and introduced genes of the transgenic ginseng plants were successfully identified by the PCR. Especially the transgenic ginseng plants were regenerated using new techniques such as repetitive single somatic embryogenesis.

The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

The photoluminescent(Zn, Cd)S: Ag phosphors are prepared by firing at 750℃, 850℃, 950℃ and 1050℃ in N_2 gas of atmospheric pressure for an hour. They are doped with(1) an activator Ag_2S(2) both an activator Ag_2S and each different flux; NaCl, NH_4C1, NH_4Br. The crystal structure of(Zn, Cd)S: Ag phosphors powder is the mixed phase of cubic and hexagonal. The photoluminescent cells are made with these phosphors and their emission spectra are measured at room temperature after these materials are excited with 3650A˚ (3.4eV) light. All these fluxes are found out to help the doping of the impurity energy level. The following results are also observed about (Zn, Cd)S: Ag phosphors. (1) Sufficient concentration of flux is enough with10^-2mole/mole(Zn, Cd)S. (2) (Zn, Cd)S: Ag phosphors with flux NH_4Br is stronger intensity than that of the orthers. (3) Variation of PL intensity of (Zn, Cd)S: Ag phosphors against gr molecule of flux seems to increase with logarithmic function like.

ICAO체제에서의 다자간 항공자유화의 추진배경

양한모,이영혁,신홍균 한국항공대학교 1996 論文集 Vol.34 No.-

1944년 시카고 조약을 중심으로 운영되어온 ICAO체제는 각국의 영공주권원칙에 기초하고 있다. ICAO 체제하에서 각국은 자국내의 항공운송에 대한 통제권을 행사하여 왔고, 국가간의 항공운송은 해당 영공국가의 허가를 받아 이루어져 왔다. 특히 각국은 국제항공운송을 위해 당사국들간의 양자협정을 통해서 상호 항공운송권을 교차 허가하는 방식을 택하여 왔다. 그러나 최근에는 각국의 항공운송권을 더 이상 양자협정방식에 의해서 허용하는 것이 아니라, 다자간 협정에 의해서 허용함으로써, 각국의 항공운송시장을 자유화하는 것이 항공사의 이익과 여객의 편의 및 경제적 이익을 위해 필요하다는 주장이 강력히 제기되고 있다. 이는 미국 및 유럽을 비롯한 주요 선진국들의 항공정책에서도 어느 정도 수용되고 있는 추세이다. 이에 ICAO는 미래의 국제항공질서의 재편 차원에서 다자간 항공 자유화에 관한 수차례의 국제회의를 개최한 바 있으며, 현재 가장 바람직한 질서의 구축을 위한 의견을 수렴하고 있다. 본 연구는 다자간 항공자유화의 최근 동향을 분석하여 우리 나라의 국제항공정책의 수립을 위한 정책자료를 제공하고자 한다. 구체적으로 현재의 다자간 국제항공질서의 형성과정과 그 주요 내용을 정리하여, 향후 전개될 항공질서의 재편의 향배를 예측하고자 하였으며, 아울러 ICAO가 개최한 주요 국제회의에서 표명된 국제항공질서의 진로에 관한 전문가들의 의견과 각국의 국제 항공정책을 분석하고 있다. 또한 그러한 분석을 바탕으로 하여 우리나라의 대응방안에 관한 정책 제안을 담고 있다. The ICAO system established by the Chicago Convention of 1944 based upon the solemn recognition of the sovereign right of each State over air space, within which each State is entitled to have the right of controlling air transport within his own territory. This made the bilateral air transport agreement between each State be a common legal form of allowing air transport right to the carriers of the other side. However, multilateral approach for liberalizing the world air transport market is strongly put forward around aviation community. It is claimed that multilateral agreement is a better form of assuring the interest of air carriers as well as passengers than bilateral agreement. Some major powers, such as U.S.A. and member of European Union, have shown their positive attitude toward that approach. In such context, The ICAO has convened recently a few international conference. Taking into consideration such recent development in this field, we illuminate the formation and status of current international air transport order, and analyze the major States' air transport policy in order to allow more reliable prevision of future development.

An alternative design to conventional class Ⅱ cavity preparation for proximal carious lesions is the tunnel preparation. It preserves the marginal ridge intact, thus making it possible to maintain the natural contact relationship with the adjacent tooth and minimize tooth reduction. This in vitro study was purposed to evaluate the effect of the materials' elastic constants and shear-bond strength on the marginal ridge fracture resistance of teeth restored by the tunnel technique, and to find the materials of choice for tunnel restorations. ??, ??, ??, and Tytin were used as restorative material. The elastic constants of each restorative material were evaluated by ultrasonic pulse measurement. Young's modulus and bulk modulus of the restorative materials were evaluated in three speimens for each material type. The shear-bond strength of the restorative materials to the dentin surface was measured after thermocycling 400 times between 6 and 60℃, using ten specimens for each material type. For measuring marginal ridge strength, 60 sound extracted molar teeth were distributed into six groups by size. Sound molar teeth were used as a Control group and unfilled prepared teeth were grouped as Unrestored. Another four groups were named Resinomer group, Ketac-Silver group, Miracle Mix group, and Tytin group by type of restorative material. Tunnel cavity preparation was done with # ½, 2, and 4 round burs in sequence. Initial access to proximal surface was made through an occlusal access preparation started at least 2㎜ from the marginal ridge, and the proximal opening was formed about 2.5㎜ below the marginal ridge. After restoration and thermocycling, marginal ridge strength was measured using a universal testing machine. The results were as follows : 1. The Young's modulus of ?? was 63.95 GPa, followed by ?? 27.60 GPa, ?? 18.48 GPa, and ?? 10.74 GPa showing significant differences between the groups(P<0.05). The bulk modulus of the materials showed the same order as Young's modulus. The value of ?? showed 59.57 GPa indicating that it will deform less than other materials under the same stress. It was followed by ?? 23.57 GPa, Miracle ?? 12.50 GPa, and ?? 11.60 GPa. 2. The Resinomer group had a shear-bond strength of 7.41 MPa which was significantly higher than those of the Ketac-Silver group (1.80 MPa) and the Miracle Mix group (2.84 MPa)(P<0.01). All the specimens of Tytin group detatched from the dentin surface during thermocycling. 3. The mean marginal ridge strength of the Unrestored group(46.14 kgf) was significantly lower than that of the Control group (84.24 kgf)(P<0.01). The marginal ridge strength of teeth restored by the tunnel technique was, in order, Ketac-Silver group 74.06 kgf, Miracle Mix group 73.36 kgf, Resinomer group 63.47 kgf, and Tytin group 58.76 kgf. The Ketac-Silver, Miracle Mix, and Resinomer groups showed no significant difference with the Control group(P>0.05), but the Tytin group showed significantly lower strength compared to the Control group(P<0.05). The results showed that the marginal ridge strength of the teeth restored by the tunnel technique was not significantly lower than that of sound teeth. They also demonstrated that the bonding strength of the restorative material to the tooth surface should be high and the modulus of elasticity should not be lower than that of the tooth in order to restore the marginal ridge strength to its natural condition.

본 연구는 목재로서 활용가치가 적은 수피(bark)를 활용하여 수질오염물질을 제거할 수 있는 여과 시스템에 대한 기초연구로서 소나무의 일종인 loblolly pine(Pinus taeda L.) 수피의 인(PO_(4)-P) 흡착특성을 연구하였다. 실험에 사용된 수피는 입상형태로서 polyallylamine hydrochloride로 전처리하여 회분식 등온 흡착실험을 수행하였다. 회분식 등온흡착실험은 수용액 pH 3~pH 8범위에서, 인의 농도별(10, 20, 30, 40 mg/L)로 수행하였다. PH 5에서 가장 높은 인 제거 효율을 나타냈으며, 수용액의 pH는 실험 후 pH 3으로 감소하였다. 이러한 감소는 수피에 의한 phosphate의 흡착이 Lewis acid-base 반응으로서 이 과정에서 H^(+)의 방출로 인하여 나타난 현상인 것으로 여겨지며, 주된 반응 메카니즘은 더 연구할 필요성이 있다. 인 흡착은 초기에 빠른 속도로 진행되었으며 대략 200분 이후에 평형에 도달하였고, 시간이 지날수록 흡착양이 증가하는 경향을 보였다. 인의 흡착특성결과는 Langmuir 등온흡착식과 Freundlich 등온흡착식으로 설명될 수 있으며, 등온흡착식 적용결과, 흡착제에 대한 최대 흡착능은 7.14mg/g이며 다른 흡착제와 비교하여 더 높았다. 실험결과와 모델에 의한 흡착능을 비교 하고자 pseudo second-order model을 적용하여 흡착 동역학 상수를 구하였다. 또한 EDXA분석으로 회분식 흡착실험 후 수피와 인이 결합되어있는 것을 확인할 수 있었다.

This study was analyzed the validity and the reliability of evaluation norm. which was used in choosing and grading events of the General Motor Ability Test. The General Motor Ability Test has been done for applicants for entrance to the department of physical education, college of education, Pusan National University. The subjects of this study were 433 applicants(men :387, women :46) for three years. They were tested in seven events : 1) 100m Dash, 2) 1500m Run(man), 800m Run (woman), 3) Throwing Hand-Ball, 4) Broad Jump, 5) Chinning(man), Flexed-Arm Hang(woman), 6) Zig-Zag Run, 7) Trunk Flexion. The results could be summerized as follows ; 1. In 100m Dash, 1500m Run, and Throwing Hand-Ball, man's average records were shown normal distribution which was inclined toward low ll grade. Therefore, the interval size of those three events must be regulated to lower. 2. Average records of Broad Jump in man were distributed into high (1) grade. So, the interval size must be adjusted to higher. 3. In Chinning, Zig-Zag Run, ad Trunk Flexion, man's average records were shawn normal distribution, and the interval size was similar to present records. 4. For woman, it was impossible to analyze correctly in all seven events because of the small number of subjects. So, it was for the sake of the reference. 5. The record of applicants for three years were operated to the variable quantity analysis. And the restults were these ; 100m Dash was F=3.0865(p<0.05), Chinning F=3.9309(p<0.05), Broad Jump F=14.7338(p<0.001), Throwing Hand-Ball F=4.9716(p<0.01), and Zig-Zag Run F=6.8297(p<0.001). Then, it was shown statistical meaningful difference in three groups. 6. In investigating the validity in choosing seven events, it was concluded that the events have been chosen reasonably. Because all events except for 100m Dash, and Zig-Zag Run in man were independent. From the analysis of the General Motor Ability Test, we could realized the necessity of regulating the standard and the interval size in several events. Then, we proposed the new evaluation norm which was suitable to present situation.

M. Heidegger에 있어서 存在물음

양영웅 제주대학교 1989 논문집 Vol.29 No.-

M. Heidegger versucht, das Horizont fur die Interpretation des Sinnes von Sein uberhaupt freizulegen. Und er sucht den Leitfaden im Menschen als Dasein, fur das man gewisses Seinsverstandnis hat. Das Sein selbst, das das Seinsverstandnis und die Fahigkeit hat, nach dem Sein selbst zu fragen, nennt er Exitenz. Diese Seinsstrukturen des Existenzz werden Existenzialien genannt. Bevor er den Sinn von Sein selbst fragt, analysiert er das Dasein existenzial. Da diese vorliegende Arbeit vor der von Heidegger entwickelten Seinsanalyse die Strukturen der Frage und Wissenschaftlichen Methoden zu erklaren versucht, betrachtet die Arbeit die Phanomenologie als wissenschaftliche Methoden, die Notwendigkeit der Seinsfrage und die Strukturen der Frage zu erlautern.
