Bangah(Agastache rugosa O. Kuntze), one of the herbs grown in Korea, was investigated for its antioxidant activity. Several antioxidative fractions was obtained from Bangah powder by extraction with variours single and mixed solvents. The free, esterified and insoluble-bound phenolic acids were fractioned with using methanol - acetone solvents and added into the soybean oil and lard at the level of 200ppm. The antioxidative activity was measured by peroxide value, carbonyl value and induction time during storage at 60℃. The results were as follows : 1.The extract yield obtained from Bangah powder was increased as the polarity of the solvents increased. 2.The antioxidative effect of the Bangah extracts obtained with single solvent extraction was found in lard in the order of dioxane>methanol>ethyl ether, while those extracts showed little effects on soybean oil. Extraction with using mixed solvents showed no significant improvement in the antioxidative effects. 3.A significant antioxidative effect of phenolic acid fraction was observed on lard, while the effecet was little on soybean oil. The insoluble phenolic arid fraction among the three phenolic acid fractions showed the highest antioxidative effect. When the phenolic acid fractions were added in the range of 200∼1000ppm, the antioxidant effect was observed at 1000ppm for soybean oil and 400ppm for lard.

TPP협정의 환경보호 및 생물다양성 보전 관련 조항의 해석 및 적용

최원목,이규옥 梨花女子大學校 法學硏究所 2016 法學論集 Vol.21 No.2

2015. 10. 5. 타결된 환태평양경제동반자협정(TPP)은 협정문 상 별도의 환경챕터를 두고, 국제사회가 새롭게 당면하고 있는 환경 문제들을 적극적으로 반영하고 있다. 특히 동 협정 제20.13조는 ‘무역과 생물다양성(trade and biodiversity)’이라는 주제 하에 생물다양성의 보전 및 지속가능한 이용 증진 의무, 토착지역공동체(ILCs)의 지식과 관행 존중, 사전통보승인(PIC) 및 이익공유와 상호합의조건(MAT)등 이에 관한 내용을 규정하고 있다. 사실 이 같은 생물다양성 관련 규정들은 생물다양성협약(CBD)이나 나고야의정서 등 환경협정에서 주된 논의의 대상이었음을 떠올릴 필요가 있다. TPP의 환경챕터 상의 조항들은 선언적 규정과 의무적 규정이 혼재되어 있는 특징을 보인다. 더욱이 TPP 협정의 생물다양성 관련 조항들은 CBD협약과 나고야의 정서상의 구체적인 모습을 모두 실현하고 있는 것은 아니며 경우에 따라서 다소 불분명하고 소극적 태도를 취하고 있다. 우리나라는 나고야의정서 가입국이지만 아직 국회의 비준이 이루어지지 못하였다. 따라서 빠른 시일 내에 국회의 비준이라든지 관련법 제정이 이루어질 것으로 예상된다. 한편 TPP 가입을 준비하고 있는 우리로서는 동 TPP 협정이 추구하는 높은 개방성, 높은 환경보호의무 등에 대하여 국내의 이행체계를 전반적으로 점검해야 할 것이다. 특히 생물다양성 보전과 유전자원 이용과 관련한 문제들은 나고야의정서의 차원을 넘어, TPP라는 무역협정의 맥락에서 대비가 이루어져야 할 것이다. 따라서 본 연구에서는 환태평양경제동반자협정(TPP)의 환경챕터 상에 나타난 전반적인 환경조항 및 생물다양성 관련 규정들을 분석하여, 생물다양성 보전과 유전자원 접근 및 이익공유의 수단으로서의 TPP의 범위와 한계를 고찰해보고, 동시에 동 규정들의 집행력과 실효성을 평가해 봄으로써, 향후 우리나라의 TPP 가입시 이행방안에 대하여 제시하고자 한다. The Trans-Pacific Strategic Economic Partnership(TPP) was concluded on October 10, 2015. it reflects the new environmental challenges facing the international community. The TPP Agreement has the independent environmental chapter. In particular, Article 20.13 deal with ‘trade and biodiversity’. Specifically it include a obligation to promote environmental conservation and sustainable use of biodiversity, respect for the knowledge and practices of indigenous and local communities(ILCs), prior informed consent(PIC), sharing of benefit, mutually agreed terms(MAT), etc. This kind of regulations have mainly discussed in environmental agreements such as the CBD and the Nagoya Protocol. The provisions of the TPP Environmental Chapter are a mix of declarative and mandatory provisions. Moreover, the provisions on biodiversity in the TPP Agreement do not fully realize the specific features of the CBD and the Nagoya Protocol. In some cases, It is featured that interpretation of its provisions are not clear. Korea is a member of the Nagoya Protocol. It is anticipated that the National Assembly approval process will be implemented as soon as possible and that related laws will be enacted. On the other hand, our government is preparing to join TPP, so we should thoroughly review the domestic implementation system against the high openness and high environmental protection obligation pursued by the TPP Agreement. Particularly, the issues regarding the conservation of biodiversity and the use of such genetic resources should be thoroughly prepared in case of multilateralism in the context of TPP, not Nagoya Protocol. Therefore, this study will analyze the overall environmental provisions and the related regulations including biodiversity conservation and sharing of benefits in the TPP environmental chapter. Also we will review the scope and limits of TPP as a means of biodiversity conservation. At the same time, by evaluating the enforcement and effectiveness of these regulations, it can be suggested how to implement TPP in Korea in the future.

SPME와 GC/MS를 이용한 녹나무 향기성분 특성분석

원미미,차은주,윤옥경,김남선,김건,이동선 서울여자대학교 자연과학연구소 2007 자연과학연구논문집 Vol.19 No.-

Recently, land managers have come to realize that, outside Asia, camphor trees grow like street-tree or weeds, infesting forests and displacing native trees. This is because camphor trees are prolific seed producers that do not have serious predators or diseases outside their native range. The camphor tree (Cinnamomum camphora), belongs to lauraceae, is the aromatic evergreen tree from which camphor was derived. Headspace solid-phase microextraction (HS-SPME) and GC-MS were applied for the analysis of volatile fragrances emanated from camphor tree. Divinylbenzene / Carboxen / PDMS fiber was used for HS-SPME adsorption materials. (+)-Camphor (31.00%) and cineol (21.89%) were found as the major volatile aroma components from Chinese camphor tree, whereas (+)-camphor (62.06%) and β-caryophyllene (10.01%) from Japanese camphor tree. Camphor tree is a promising garden tree for well-being.

주지적 교육관과 낭만적 교육관에 있어서 교양교육의 의미

옥치곤,이원조 진주산업대학교 1992 論文集 Vol.31 No.-

This study is and attempt to clarify the nature or meaning of liberal education, form the perspective of two dominant lines of education ideas developed in modern societies, i.e., the Intellectualism and the Romanticism. Intellectualism seems to be sound and valid when it seeks the meaning of freedom in the social enterprise. But unfortunately, the intellectualists have paid little attention to methodic principles for the child to be educated and autonomous. Romantists in general conceive education to be of embodiment of the natural goodness and inner potentiality. According to them, education aims ultimately at one's self-realization. Critics of this view often mention that they devaluate the socie-cultural character of the human mind. Romantists are criticized in that they understand the individual as one antagonistically against the society, and that the individual's freedom may be attained when he lives away form social controls.

Arthur Miller 의 The Crucible에 나타난 良心

梁原玉 順天大學校 1985 論文集 人文社會科學篇 Vol.4 No.-

Arthur Miller's The Crucible is a play about the Salem Witchcratf Trial in 1962. Although it is on the historical precedent, the play is a drama of universal significance showing the sense of guilt and conscience. Miller links the characteristic of Salem society with the situation during the McCarthy investigations, when people suffered similarly from a guilt resulting from their awareness that they were not as Rightist as people were supposed to be and when he saw men handing conscience to other men and thanking other man for the opportunity of doing so. In the Crucible we see Proctor, the character of centeral interest in the play, leads the opposition to the witch-hunt until he himself is accused, and it is his final stand on his innocence which ensures that the victims will be looked on as martyrs and that the hunt will be halted. As the witch-hunt begins and his wife, Elizabeth, is accused, Proctor's human goodness is revealed. His sin is not witchcraft, but adultery. Even if he has the respect of the community, it makes him feel a fraud and undermines his self-confidence. Proctor cannot get rid of his guilt and he does want to stay alive with Elizabeth when he awaitshanging,' with those few others who have stood firm in their genuine innocence of life and refused to confess to witchcraft. He decides to tell his lie and accept the loss of his good name in the eyes of all men. But he cannot belie his fellow victims, even though he can belie himself. He stands firm against great pressure and the threat of the gallows. When he decides to die, he finds some shred of goodness in him. His load of guilt has fallen off at last, like christian's at the foot of the Cross, and he can stand upright and choose his death like the good man he truly is, justified at last in his own judgement. Miller has the professional crusader's zeal for humanity. And he, in Proctor, wants to show us the last remnant of pride that save us. His chief struggle as an artist and as a public figure is to reinvest the individual with a moral responsibility, showing us that Proctor wants to be left alone with his wife and his farm by making a false confession, but in the end he goes to his death for the moral responsibility and conscience. In conclusion, moral conscience is essential to the world that would be perfect when individuals are unjustly frustrated, tortunred, sacrified in the rotten society. It is conscience as a private matter that makes the world a friendly place, for our society nees such a conscious hero like Proctor. Miller seems to believe that if conscience is not handed over not only to the state or the mores of the time but to one's friend or wife the world will be just and bright. That is Miller's optimism for the future world.

초음파 모터의 위상차 조절과 위상차-주파수 다중 조절에 따른 속도 특성

김동옥,김원배,오금곤,최한수,김영동 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.2

To control the position, velocity and torque of the ultrasonic motor, a great variety of method are proposed such as the amplitude, phase difference, frequency and so on. In the case of phase difference method, it has some advantages; it can control the direction and velocity of rotation only adjusting the phase difference and it has wide control-band. During the USM driving on adjusting phase difference, its characteristic was transformed by the change of resonance-frequency of stator, which means that the resonance frequency is different according to the phase difference. Consequently, we need to set up the most suitable driving frequency according to each phase difference.
