이정선,김종심 국립특수교육원 2003 특수교육연구 Vol.10 No.1

본 연구는 초등학교 특수학급에서 특수교사는 특수아동들을 어떻게 통제하고 특수아동들은 이에 어떻게 대응하는지를 분석하는데 목적이 있다. 이러한 연구 목적을 달성하기 위해 약 12개월 간 전라남도 H군에 위치한 Happy초등학교의 특수학급을 대상으로 문화기술적 방법으로 자료를 수집하고 분석하였다. 학습지도와 생활지도로 나누어 바람직한 행동을 강화하고 바람직스럽지 못한 행동을 줄이는 특수교사의 통제 전략과 특수아동의 대응 전략을 분석하고, 통제의 발생원인과 의미에 대해 분석하였다. 일반학급에서의 학생통제와 구별되는 특수아동 통제의 특징을 밝힘으로서 특수학급에서 효과적인 통제방식으로 강압적 통제와 인간 중심적 통제의 조화로운 활용을 제안하였다. The purpose of the study is to describe the phenomena of exceptional children's control, and to explore the meaning and the distinctive features of the control in a special classroom of the elementary school. For this purpose, the study proposed the three research questions, i. e., control and coping strategies, the meaning of control, and features of exceptional children's control. The study was conducted by ethnographic research method for 12 month in the special classroom(resource room) of the Happy Elementary School located in Chonnam Province. Ethnographic data were collected and analyzed by participant observation and in-dept interview. Major findings can be summarized as follows: First, teachers' control strategies for the exceptional children can be divided into teaching subjects and guidance area. And special educators implemented both (1) control strategy of the reinforcement for desirable behaviors and (2) for the decrease of undesirable behaviors among exceptional children. Second, students in the study tried to copy with the teachers' control by implementation of (1) positive opposition, (2) negative opposition, and (3) no reaction strategies. Third, special educators and exceptional children's recognition on the cause of humanity oriented control were the same as (1) encouragement vs. doing well (2) prevention vs. caring for (3) concern vs. love. But both of their recognition on the cause of coercive control are different: (1) short endurance vs. boring (2) lake of effort vs. difficulty of subject (3) individual character vs. teaching method. Fourth, special educators and exceptional children interpreted cohesive control as the same:‘encouragement’vs.‘love’. But their interpretations of the coercive control were different, i. e., education' vs.‘letting off steam’. Fifth, the control strategies of special classroom were different from that of integrated classroom: (1) individual control vs. group control (2) humanity oriented control vs. rule oriented control (3) preventive control vs. prescriptive control. In conclusion, this study suggests that the most effective control in special classroom is the harmonious implementation of the humanity oriented control and the coercive control.

The effects of seed soaking treatment with the solutions of plant growth regulators IAA, GA3 and BAP on seed germination and shoot and bulb growth of Allium victorialis var. platyphyllum (Korean wild garlic) were determined. A significant variation in the seed germination rate was recorded at all treatments for various soaking periods. Maximum seed germination was obtained when seeds were soaked in IAA or GA3 solution at 200 mg L-1. The MAP treated seeds started to germinate after 3 months. Among treatments, IAA was found to be most effective in improving seed germination, but further seedling growth was not correlated to the soaking time. Seed soaking in IAA or GA3 solution enhanced further growth of seedlings compared with water control treatment. Shoot and bulb growth was highest in GA3 treatments.

An efficient method for the rapid propagation of Smilax china from axillary buds was established. Plants with thick leafage were selected from Korea native S. china population. Axillary buds of S. china collected from selected plant and were cultured in various culture media (2MS, MS, 1/2MS, WPM, B5 and SH medium). Shoot was induced from axillary bud on MS basal medium after 4 weeks of culture. 1/2MS medium showed a higher growth rate than those of the others, while the lowest shoot growth was obtained in 2MS medium. Among the sucrose concentrations, 5% sucrose was the optimum level for shoots growth from axillay buds. Among cytokinins, 0.5 mg L -1 6-benzylaminopurine (BAP) treatment showed the best performance on shoot multiplication, yielding average shoot multiplication forming about 2.4. Rooting was induced directly near the base of the shoot on 1/2MS medium containing with three-auxins α-napthalene acetic acid (NAA), indole acetic acid (IAA) and β-indolebutyric acid (IBA) (0.5 and 1.0 mg L -1 ). The 1.0 mg L -1 IBA treatments induced earliest rooting with maximum of root number and root growth. These rooted plantlets were successfully transferred to pots for 4 weeks hardening process, and were transferred to soil with above 90% survival rate.

Effects of inorganic salts on biomass production, cell wall components, and bioethanol production in Nicotiana tabacum

Seon Jeong Sim,Seong Hyeon Yong,Hak Gon Kim,Myung Suk Choi,Pil Son Choi 한국식물생명공학회 2021 JOURNAL OF PLANT BIOTECHNOLOGY Vol.48 No.4

The development of bioenergy through biomass has gained importance due to the increasing rates of fossil fuel depletion. Biomass is important to increase the productivity of bioethanol, and production of biomass with high biomass productivity, low lignin content, and high cellulose content is also important in this regard. Inorganic salts are important in the cultivation of biomass crops for the production of biomass with desirable characteristics. In this study, the roles of various inorganic salts in biomass and bioethanol production were investigated using an in vitro tobacco culture system. The inorganic salts evaluated in this study showed dramatic effects on tobacco plant growth. For example, H2PO4 substantially improved plant growth and the root/shoot (R/S) ratio. The chemical compositions of tobacco plants grown in media after removal of various inorganic salts also showed sig- nificant differences; for example, lignin content was high after Mg2+ removal treatment and low after K+ treatment and H2PO4 removal treatment. On the other hand, NO3- and H2PO4 treatments yielded the highest cellulose while enzymatic hydrolysis yielded the highest glucose concentration ratio 24 h after NH4+ removal treatment. The ethanol productivity after H2PO4 removal treatment was 3.95% (w/v) 24 h after fermentation and 3.75% (w/v) after 36 h. These results can be used as the basis for producing high-quality biomass for future bioethanol production.

용매추출법에서 희토류 금속을 효과적으로 분리하기 위해 추출제만 사용하는 것이 아니라 crown ether와 같은 첨가제를 이용하는 연구를 하였다. Host-guest 화합물인 macrocyclic ligand는 금속과 착화물을 형성하는데, 이 때 crown ether의 cavity 크기와 비슷한 크기의 금속 이온들과 안정한 착화물을 형성한다. 이전 연구에서 europium과 yttrium을 분리하기 위해 여러 사슬 길이의 지방산 추출제를 이용한 추출실험을 행하였었다. 이를 토대로 분리효율이 좋지 않았던 hexanoic acid에 크기가 다른 crown ether (18-crown-6 ether, 15-crown-5 ether, 12-crown-4 ether)를 첨가하여 분리효과가 증가하는 것을 연구하였다. hexanoic acid의 농도별로 분리효율을 본 후 가장 분리 효율이 좋은 농도에서 crown ether를 종류와 농도를 다르게 하여 첨가하였다. 그 결과 0.05 M hexanoic acid에서 분리능이1.72으로 가장 높게 나타났고, crown ether를 첨가하였을 시 분리능이 0.002 M 15-crown-5 ether에서가장 높게 나왔으며 기존의 분리능보다 2배 이상 더 높았다. 또한 crown ether를 첨가하였을 때 두 금속이 MLR3·3RH의 형태로 추출되는 것도 확인 할 수 있었다. The synergistic solvent extraction of rare earth elements such as europium and yttrium has been investigated by the extractant with crown ether as an additive. Macrocyclic ligand as host-guest compounds form more stable complexes with metal ions which have the similar size of the cavity of crown ether. In our previous study[14] founded that the extraction used fatty acid of the various alkyl chain length. Based on the results of the previous experiment, the synergistic separation effect of two metals investigated that the hexanoic acid had was the worst extraction effect which added a crown ether such as 18-crown-6 ether, 15-crown-5 ether, and 12-crown-4 ether. In this study, the concentrations of hexanoic acid have showed the separation effect, and then the concentrations and kind of crown ether are performed for synergistic extraction at the hexanoic acid concentration of the highest separation effect. As a results, the separation rate is the highest value of 1.72 at 0.05 M hexanoic acid, and 0.002M 15-crown-5 ether is the best value in other concentrations and kind of crown ether, it is about twice of using only hexanoic acid. Moreover, the extraction species of two metals has been founded MLR3·3RH form when added the crown ether.
