정연옥,박노복,Youn Ok Jung,No Bok Park 국립한국농수산대학교 교육개발센터 2024 현장농수산연구지 Vol.25 No.4

지리산에서 자생하는 5종(참나물, 꿩의비름, 함박꽃나무, 산오이풀, 배초향)의 식물을 선정하여 5월부터 9월까지 자생지에서 꽃이 활짝 개화한 상태에서 채집하였다. 채집한 식물은 전초는 추출하여 17종의 폴리페놀 성분을 분석하고 다음으로 꽃, 잎, 줄기, 뿌리를 분리하여 각 부위의 추출물로 DPPH, ABTS, 폴리페놀, 플라보노이드에 관한 실험을 진행하였던바 결과는 다음과 같다. 1. 지리산에 자생하는 5종의 식물에 함유된 폴리페놀 성분은 총 13가지였으며 그중 가장 많은 검출된 물질의 총 함량은 산오이풀로 126.2ppm이었으며 주 물질은 ellagic acid(=ELA) 122.4ppm이었다. 2. DPPH radical 소거활성을 살펴본 결과 산오이풀의 꽃, 줄기, 뿌리에서 가장 좋았으며 다른 식물에서는 꽃 추출물에서 좋은 소거활성도를 나타냈다. 3. ABTS radical 소거활성도가 가장 높은 것은 산오이풀 꽃 추출물에서 가장 높은 13.5㎍/㎖에서였고, 뿌리 16.8㎍/㎖, 잎 22.6㎍/㎖ 순이었다. 그 외 다른 식물에서는 그렇게 큰 ABTS radical 소거활성능을 확인할 수 없었지만 전체적으로 꽃 추출물이 다른 부위인 잎과 뿌리 추출물보다 좋았다. 4. 총 폴리페놀 함량은 가장 많은 것은 함박꽃나무는 잎에서는 161.4mg GAE/g으로 가장 많았고, 다음으로 함박꽃나무의 뿌리와 배초향 뿌리에서 가장 많은 130.0mg GAE/g이었다. 또한 가장 낮은 것은 산오이풀로 나타났다. 5. 총 플라보노이드 함량은 배초향의 뿌리로 186.2mg CAE/g, 꽃에서 166.9mg CAE/g, 잎에서 가장 낮은 116.1mg CAE/g이었다. 이상의 결과에서 나타나듯 산오이풀은 항산화 효능도 우수하며 폴리페놀 성분의 함량도 많아 앞으로 화장품 산업에 충분히 이용 가능할 것이라 생각된다. Five species of plants (Pimpinella brachycarpa (Kom.) Nakai, Hylotelephium erythrostictum (Miq.) H. Ohba, Magnolia sieboldii K. Koch, Sanguisorba hakusanensis Makino, Agastache rugosa (Fisch. & Mey.) Kuntze) native to the clean area of Mt. Jiri were selected. The collection period was from May to September 2021, and the five species plants were collected in their native habitats with flowers in full bloom. The collected plants were extracted with 70% EtOH and 17 kinds of polyphenol components were analyzed. Next, flowers, leaves and roots were separated from plants, extracted with 70% EtOH for each part and experiments were conducted on DPPH, ABTS, total polyphenols, and total flavonoids. The results are as follows. 1. There were a total of 13 polyphenol components contained in the 5 species of plants native to Mt. Jiri. Among them, the total content of the most detected substance was Sanguisorba hakusanensis Makino, which was 126.2 ppm, and the main substance was ellagic acid (=ELA), which was 122.4 ppm. 2. As a result of examining the DPPH radical scavenging activity, the flowers, stems, and roots of Sanguisorba hakusanensis Makino showed the best scavenging activity, while the flower extracts of other plants showed good scavenging activity. 3. The highest ABTS radical scavenging activity was Sanguisorba hakusanensis Makino flower extract at 13.5 ㎍/㎖, followed by roots at 16.8 ㎍/㎖ and leaves at 22.6 ㎍/㎖;. Although such a large ABTS radical scavenging activity could not be confirmed in other plants, the flower extract was overall better than the leaf and root extracts of other parts. 4. The highest total polyphenol content was found in the leaves of Magnolia sieboldii K. Koch, at 161.4mg GAE/g, followed by the highest content in the roots of Magnolia sieboldii K. Koch and the roots of Agastache rugosa (Fisch. & Mey.) Kuntze, at 130.0mg GAE/g. Also, the lowest was found to be Sanguisorba hakusanensis Makino. 5. The total flavonoid content was 186.2mg CAE/g in the roots of Agastache rugosa (Fisch. & Mey.) Kuntze, 166.9mg CAE/g in the flowers, and the lowest was 116.1mg CAE/g in the leaves. As shown in the results above, Sanguisorba hakusanensis Makino has excellent antioxidant efficacy and has a high polyphenol content, so it is expected to be fully utilized in the cosmetics industry in the future.

Sunbigi tree(Vitex rotundifolia L.f.), which grows wild in the southern part of Korea and along the coast of the West Sea, has a lot of useful value in terms of resource utilization. Since ancient times, it has been used as folk medicine or herbal medicine in the private sector. Although the leaves and stems have a strong scent, the fruit also has a strong scent, so there are some studies on extracting essential oil from the fruit of Sunbigi tree and analyzing the ingredients, but there are few studies on the fragrance component by extracting hydrosol. The reason is that the fruits are hard and it is difficult to identify the active ingredients contained in the general extraction method. Therefore, in this study, the results of analyzing the components contained in the fragrance of hydrosol obtained by extracting hard fruits at high temperature by different extraction methods are as follows. 1. The extraction condition with the highest flavonoid content was 30.57 mg/g with ethanol, followed by hot water extract at 18.26 mg/g and water extract at 9.69 mg/g with the lowest. 2. As a result of distillation extraction from the fruit of Sunbigi tree, the fragrance of hydrosol is 3-Methyl-2-butenoic acid, cyclobutyl ester, Eucalyptol, L-alpha-Terpineol, 1H-Cycloprop[e]azulen-7-ol, decahydro-1 ,1,7-trimethyl-4- methylene-, [1ar-(1a.alpha.,4a.alpha.,7.beta.,7a.beta.,7b.alpha.)] were found to be many.

It was investigated how the contents of four active ingredients, nodakenin, decursinol, decursin, and decursinol angerate, which are active ingredients of Angelica gigas Nakai, cause material changes depending on the type of bacteria. Fermentation experiments were conducted using 9 types of bacteria: 5 types of Bacillus EMD17, 9-3, HCD2, #8, 191 and 4 types of Lactobacillus KCTC 3320, WCP02, S65, P1201. 1. The contents of decursin and decursinol angerate, which are indicator substances, rapidly decreased after 2 days of fermentation by inoculating Bacillus bacteria in the extract of Angelica gigas Nakai. Even after 4 days of fermentation, the contents of decursin and decursinol angerate were the same as on the 2nd day. On the other hand, the content of nodakenin and decursinol increased after 4 days of fermentation. In addition, the content of decursin increased significantly after 6 days of fermentation. 2. Substance changes of nodakenin and decursinol after inoculation of Bacillus bacteria into the extract of Angelica gigas Nakai were almost non-existent regardless of the type of bacteria. The change in effective content of decursin and decursinol angerate was large in Bacillus EMD17 and 9-3. Changes in the contents of decursin and decursinol angerate were almost non-existent in Bacillus HCD2, #8, and 191 strains. 3. As a result of finding out the change in active ingredient after 8 days of fermentation using 4 types of Lactobacillus KCTC 3320, WCP02, S65, and P1201 extracts of Angelica gigas Nakai, there was almost no change in the contents of nodakenin and decursinol regardless of the type of bacteria. However, in the case of fermentation with Lactobacillus S65 and P1201, the contents of decursin and decursinol angerate were changed.

TV 스타다큐 마이웨이 장애관 “장애인 스테레오 타입”에 관한 연구 -불굴의 비너스 김나윤을 중심으로-

정연옥 한국장애학회 2022 한국장애학 Vol.7 No.2

본 연구는 TV조선에서 방영된 TV 스타다큐 마이웨이 ‘불굴의 비너스 김나윤’ 편에 나타난 스테레오 타입 이미지를 분석하기 위하여 비판 담론적 분석을 사용하여 연구하였다. 본 연구 결과 ‘장애 문제 개인화’는 주인공이 자신의 절단된 팔을 강조하며 장애를 부각하고 있다, 출연진 중 중도장애인인 강원래는 휠체어를 탄 자신의 모습을 바라보는 사람들에게 ‘불쌍하다고 쳐다보는 거야’와 같이 타인을 향해 적대적으로 대응했던 경험을 말한다. 이는 장애 문제에 있어 개인이 책임져야 하는 사회속의 장애 인식을 나타내고 있다. ‘장애 이상한 몸’은 장애의 특정 부위를 강조하며 ‘장애’를 부각하고 있다. 그리고 ‘장애극복’은 우리 사회에 비장애인 중심의 문화를 파악할 수 있었고, ‘희생의 대상화’는 장애인을 둘러싼 가족과 친구 등의 도움과 희생을 강조하고 있다. 이와 함께 ’사회적 분리’는 장애인 전용 센터를 설립해야겠다는 내용을 말하며, 이는 장애인과 비장애인 사이의 계층 간의 분리를 의미한다. 이와 더불어 주인공을 ‘슈퍼장애인(supercrip)’으로 묘사하고 있다. 본 연구는 “장애(인) 스테레오 타입”을 벗어나 장애를 논하거나 연출하는 것의 출발점에 있어 제작자의 사고방식과 감수성, 관점을 정립하고 장애에 대한 왜곡된 인식을 제거하며 사회적으로 장애인식을 재고하도록 하는 것에 의미를 둘 수 있다.

In this study, we compared the differences in stresses and psychological adjustments between the children of divorce and the children in intact families. We also investigated the differnces in the moderating effect of parental attitudes on the relationship between stresses and psychological adjustment. Furthermore, in case of divorced group, we tested moderating effect of fear of abandoment on the relationship between stresses and psychological adjustments. We found that the children of divorce had a higher stress level, perceived parental attitudes more negatively and suffered more psychological maladjustments such as somatic complaints, anxious/depressed symptoms than the children in intact families. The hierarchical multiple regression analysis showed that the parental warmth and supervision factors moderated the negative relationship between stressful life event and anxious/depressed symptoms significantly in the group of children of divorce, but insignificantly in the group of children in intact families. In the group of children of divorce, the fear of abandonment factor was found to moderate the negative relationship between life stresses, anxious/depressed symptoms and delinquent behaviors significantly. It is suggested that the fear of abandonment is a factor more important than parental attitudes in the treatment of psychological maladjustments of the children of divorce. 이혼집단의 경우, 여학생이 남학생에 비해서 높은 수준의 신체증상을 경험하는 것으로 보인다. 또한 지각된 유기공포는 스트레스와 우울/불안 간의 관계를 완화하는 것으로 나타났다. 이러한 상호작용효과를 보다 구체적으로 이해하기 위해서 앞서 기술한 것처럼 도시화하였다. 즉 유기공포 고(평균에서 1표준편차를 더한 점수), 저(평균에서 1표준편차를 뺀 점수)수준에 따라 변화하는 스트레스와 우울/불안간의 관계를 도시화하여, 그림 2에 제시하였다.그림 2에서 볼 수 있듯이, 스트레스 수준이 낮을 때(평균에서 1표준편차를 뺀 점수 기준) 유기공포의 수준에 따른 우울/불안 수준의 차이에 비해서, 스트레스 수준이 높을 때(평균에서 1표준편차를 더한 점수 기준) 유기공포의 수준에 따른 우울/불안증상 수준의 차이가 더 크다. 즉 이혼집단에서 스트레스와 우울/불안수준간의 부정적 관계는 유기공포 수준이 낮을 때 경감됨을 시사한다.비행공격성예언변인단계BβR2 △R2단계BβR2 △R2성별1-.17-.04-.01.0011.56.14.01.02스트레스2 .26.39.16.17*2.80.43.21.20*유기공포3.34.18.18.03**31.27.23.26.05**스트레스 x 유기4.11.18.21.03**4.13.07.26.01* p<.001 ** p<.05 *** p<.005

The purpose of this study was to investigate young children's patterns of lying and moral judgments according to age and the kinds of stories involved. The participants included 268 four-and five-year-old children attending one of seven educational institutes for young children in Gyeonggi Province. The investigator conducted 1: 1 interviews with the participants in order to better understand their conception of lies and their perceptions of right and wrong. The measurements consisted of 14 stories about lying. The data collected were analyzed by mean, percentage, and t-test. The research findings are as follows: First, there were age differences in children's ability to judge a lie. Five-year-olds did a better job in their judgments about lying than four-year-olds, whether a story was a lie or not. In particular, the four-year-olds made worse judgments when the story was not a lie than when it was in fact a lie. Second, there were age differences also in children's moral judgments. Third, clear differences were found in the young children's judgments in regards to lying, in terms of the kinds of stories involved. Fourth, there were differences in young children's judgements of right and wrong according to the lying judgments and the kinds of stories involved. They considered lies told with bad intentions and those told in self-defense to be bad, but also judged the lies which produced negative consequences to be bad for some stories, which indicates that the kinds of stories involved play a role in children's moral judgments. In conclusion, it was found that children's intention-based judgments of lies and their conception of right and wrong depends on their age and the kinds of stories being told.
