  • This study examines mutual perceptions between general public and nuclear plant employees on understanding nuclear policy communication applying the co-orientation model. The total of 414 responses were analyzed including 211 of the general public and 203 of plant employees. Results indicate that agreement between general public and plant employees is relatively high, in that general public tends to have negative evaluation to nuclear policy communication, but plant employees tends to have positive one. In terms of congruence, general public perceive that plant employees might have more positive evaluation than themselves, and nuclear plant employees perceive that general public might have more negative evaluation than themselves. Finally, in terms of accuracy, general public accurately estimate how nuclear plant employees perceive on policy communication, whereas nuclear plant employees unaccurately estimate how general public perceive on policy communication.

  • 구지뽕 나무(Cudrania tricuspidata Bureau)는 일반적으로 이용되는 대표적인 다년생의 약용식물이다. 최근 국제적 추세에 따라 자국의 유전자원의 발굴, 보존 등이 강화됨에 따라 인접국가와 국내 자생 꾸지뽕 계통을 판별 할 수 있는 기준설정에 관한 연구의 필요성이 대두되고 있지만, 분자생물학적 판별 기술의 개발은 아직 미흡한 실정이다. 본 연구에서는 국내 토종과 중국 계통의 구지뽕 나무의 기원을 판별하기 위해 엽록체에 존재하는 trnL-trnF 유전자단편에서 SNP를 이용한 판별 프라이머를 확보하였으며 이를 보완하여 보다 신속하게 판별하기 위하여 ARMS-PCR기술을 이용한 판별마커와 그 조건을 확립하였다. 그러므로, 본 연구에서 개발된 SNP 마커는 다양한 지역에서 서식하는 구지뽕 계통들의 신속한 확인을 위해 매우 유용하게 이용될 것으로 생각된다.

  • Background and objective: This study was conducted to find out the status of plant utilization in the current textbooks by analyzing the plants by grade and subject in the national textbooks for all elementary school grades in the 2015 revised curriculum in Korea. Methods: The data collected was analyzed using Microsoft Office Excel to obtain the frequency and ratio of collected plant data and SPSS for Windows 26.0 to determine learning content areas by grade and the R program was used to visualize the learning content areas. Results: A total of 232 species of plants were presented 1,047 times in the national textbooks. Based on an analysis of the plants presented by grade, the species that continued to increase in the lower grades tended to decrease in the fifth and sixth grades, the upper grades of elementary school. As for the number and frequency of plant species by subject, Korean Language had the highest number and frequency of plant species. The types of presentation of plants in textbooks were mainly text, followed by illustrations and photos of plants, which were largely used in first grade textbooks. In addition, as for the area of learning contents in which plants are used, in the lower grades, plants were used in the linguistic domain, and in the upper grades, in the botanical and environmental domains of the natural sciences. Herbaceous plants were presented more than woody plants, and according to an analysis of the plants based on the classification of crops, horticultural crops were presented the most, followed by food crops. Out of horticultural crops, flowering plants were found the most diversity with 63 species, but the plants that appeared most frequently were fruit trees that are commonly encountered in real life. Conclusion: As a result of this study, various plant species were included in elementary school textbooks, but most of them were horticultural crops encountered in real life depending on their use. Nevertheless, plant species with high frequency have continued a similar trend of frequency from the previous curriculums. Therefore, in the next curriculum, plant learning materials should be reflected according to social changes and students' preference for plants.

  • 본 연구는 우유, 두유, 기타 식물성 대체우유에 대한 객관적 이해를 바탕으로 식물성 대체우유를 바르게 이용하도록 돕기 위한 교육자료로써 카드뉴스를 개발하였다. FGI 대상자는 우유, 두유, 기타 식물성 대체우유 중 한 가지라도 최근 3개월 이내에 직접 구입하여 한 달에 한 번 이상 섭취한 사람이며 이들 중 두 가지 이상 섭취한 경우에는 섭취 빈도가 높은 것에 배정하였다. 이 기준에 맞는 19~65세 미만 남녀 17명(남자 9명과 여자 8명)을 편의추출법으로 선정하여 대상자를 구성하였다. 면담은 연령대별로 나누어 연구자가 대면이나 ZOOM으로 가이드라인에 따라 진행하였다. FGI를 통해 식물성 대체우유에 대해 대상자가 궁금해하거나 바른 소비를 위해 알아야 하는 정보를 선정하였다. 선정된 정보를 중심으로 쉽고 간결하게 콘텐츠를 구성한 후 식물성 대체우유의 주 소비자인 MZ 세대의 감각에 맞춰 디자인하여 온라인에서도 활용할 수 있는 10 페이지 분량의 카드뉴스를 완성하였다. 카드뉴스 콘텐츠 제작 시 최신 학술 동향을 담도록 하였으며 카드뉴스 시안에 대하여 전문가 자문 및 잠재 소비자 검토를 받아 수정과정을 거쳤다. 이상에서 본 연구를 통해 식물성 대체우유에 관한 카드뉴스 형식의 교육자료를 개발하였으며, 앞으로도 빠르게 변화하고 있는 식품 소비 트렌드를 반영한 교육자료 개발과 공급이 활성화되고 가정 교과 및 학교 밖 식생활교육에서도 관련 연구와 적용에 발맞춰나가야 할 것으로 생각된다.

  • Three Angelica sinensis polysaccharide fractions (APFs), named APF1, APF2 and APF3, were isolated and purified from Radix A. sinensis and their antioxidant activities were evaluated in isolated mouse peritoneal macrophages by pretreatment with APFs before exposure to 0.2 mM tertbutylhydroperoxide (t-BHP). The results showed that pretreatment of the macrophages with APFs as low as $10{\mu}g$/ml could significantly enhance t-BHP-decreased cell survival, intracellular glutathione (GSH) content and superoxide dismutase (SOD) activity, and also inhibited t-BHP-increased lactate dehydrogenase (LDH) leakage and malondialdehyde (MDA) formation (p < 0.05), and APF3 was the most active fraction, followed by APF2 and APF1 in decreasing order. Furthermore, we found for the first time that the bound-protein in APF3 was associated closely with the protective effects and the polysaccharide inhibited the excess NO release from t-BHP-activated macrophages to protect host cells.

  • This study investigated the changes of consciousness and ambivalent attitudes about the important environmental issues among the teachers who enrolled the environmental education training. Experimental and control groups were composed with 47 and 30 person, respectively. Environmental issues were constructions of sea-wall, nuclear power plant and dam. Cronbach alpha of the self-developed questionnaire was $0.6909{\sim}0.8992$. Score were made with 5 Likert scales for consciousness, and with semantic differential half scale for ambivalent attitudes. Almost teachers(94.0% and 97.1%) have above 10 years teaching career. Strangers in environmental program were 53.2%. After environmental training, teachers' consciousness was significantly changed to negative about the construction of sea-wall for the farm field and industry complex area(p=0.019), and about the construction of dam for disaster like flood(p=0.026), and for adverse effects of citizen by fog(p=0.042). They were also significantly changed to negative about the construction of nuclear power plant for economical energy(p=0.004)', no-emission of greenhouse gases(p=0.033)', 'alternative energy(p=0.000)', 'destruction of ecology(p=0.052)' and 'social fear(p=0.009)'. The consciousness of teachers who have the experience of environmental training, were significantly changed to negative about the construction of nuclear power plant. Scores of teachers' ambivalent attitudes were made lower in experimental than control group about the construction of sea-wall and nuclear power plant. After education training, they were made lower so much as -10.0% in control, but higher much as +4.4% in experimental, and severely higher much as 86.5% in teachers who had experienced the environmental training about construction of sea-wall. Their scores were made lower so much as -3.3% in control, but much as -6.4% in control.
