A new species of Huperzia (Lycopodiaceae) from Jeju Island, Korea: Huperzia jejuensis

임진아,선병윤 한국식물분류학회 2015 식물 분류학회지 Vol.45 No.1

A new species belonging to Lycopodiaceae Mirb. Huperzia Bernh. s.l. is described and illustrated: Huperzia jejuensis B.-Y. Sun & J. Lim. H. jejuensis has been considered conspecific with H. integrifolia (Matsuda) B. Øllg. ex. Z. Satou, but it is clearly distinguished by the characteristics of linear-lanceolate leaves with parallel margins from the base to the mid-part, minute dentate margins from the mid-part to the end of the leaf, and cuspidate gemma apex. Because the habitat of the new species was confined to Jeju Island, ‘jejuensis’was chosen as the specific epithet of the scientific name of the new taxon.

화이트헤드의 주체적 지향과 양자역학의 세계관

임진아 한국화이트헤드학회 2013 화이트헤드 연구 Vol.0 No.27

As for the quantum mechanics which beganin a quantum hypothesis of beginning Plank in the 20th century, a human being brought big changes two kinds in the place that interpreted nature. It collapsed a deterministic view of the world that put base for the rough going dynamic way of thinking first. It is the fact that there are the second, critical point for the recognition of nature irrelevant to the human intellectual faculty. It thought that we could completely know the motion of object(a particle)status using exercise of Newton equation. In other words, it thought position and the momentum of the current object to be can know the past and future status of the object precisely based on. When it is scientific determinism, it calls for such a thought. However, the various experiment results of the20th century let you recognize that you could not look at nature in a deterministic accident(a thought). It substituted for the deterministic view of the world, and a probabilistic view of the world would be located, and, as for this new view of the world, it was established Uncertainty principle of Heisenberg in base. When the true meaning that his uncertainty principle had disseminates that it has limitation in a human being recognizing nature for the root, it is about time when it. This report thinks to consider a probabilistic view of the world in the independent point concept of the available Potentiality of Whitehead. The`probability concept can talk with`recursion if it summarizes methodology of the natural science to establish laws and theories for nature with a word, and` recursion has close relation to probability concept. However, the concept of`probability and Born which it talked about determines mathematics and statistical probability concept and Ψ of the wave equation of Schrodinger and is nonidentical. As for the probability concept, a thing called` 'directivity' is appropriate to quantum mechanics. Then it is to point to what, and the directivity can speak a question called something. There is the point of Whitehead for the purpose of deciding the true character of the subject and means a purpose to think so that a subject comes true. It is judged that it cannot explain a quantum-mechanical unique view of the world in the concept called`'probability' enough, and it is thought that it may explain it in the point' concept of the`subjective aim of Whitehead in this more properly. 20세기 초, 플랭크의 양자가설로 시작된 양자역학은 인간이 자연을 해석하는데 있어 두 가지 큰 변화를 가져오게 하였다. 첫 번째, 고전 역학적 사고방식에 기반을 두고 있는 결정론적 세계관을 붕괴시킨 것이다. 두 번째, 인간의 지적능력과는 상관없는 자연의 인식에 대한 한계점이 존재한다는 사실이다. 우리는 뉴턴의 운동방정식을 이용해서 물체(입자)의 운동 상태를 완벽하게 알 수 있다고 생각했다. 즉 현재 물체의 위치와 운동량을 토대로 그 물체의 과거 및 미래의 상태를 정확히 알 수 있다고 생각했다. 이런 사고방식을 과학적 결정론이라 부른다. 그러나 20세기의 여러 실험결과들은 결정론적 사고로 자연을 바라볼 수 없음을 인식하게 만들었다. 결정론적 세계관을 대신해서 확률론적 세계관이 자리잡게 되었고, 이 새로운 세계관은 하이젠베르크의 불확정성원리를 기반으로 확립되었다. 그의 불확정성원리가 가진 진정한 의미는 인간이 자연을 인식함에 있어 근원적으로 한계를 가지고 있다는 것을 주지시켜주는 데 있다. 본고는 화이트헤드의 가능태이론의 주체적 지향개념으로 확률론적 세계관을 고찰하고자 한다. ‘확률’개념은 자연에 대한 법칙과 이론을 정립하기 위한 자연과학의 방법론을 한마디로 요약한다면, ‘귀납’이라고 말할 수 있고, ‘귀납’은 확률개념과 밀접한 관계가 있다. 그렇지만 수학이나 통계학의 확률개념과 슈뢰딩거의 파동방정식의 Ψ를 ‘확률’이라고 말한 보른의 개념은 결코 동일하지 않다. 양자역학에서의 확률개념은 ‘지향성’이라고 하는 것이 적절하다. 그렇다면 무엇을 지향하는 것이며, 지향성은 무엇인가 하는 물음이 생긴다. 화이트헤드의 주체적 지향은 주체의 본성을 결정하는 목적이며, 주체가 실현하고자 하는 목적을 의미한다. 양자역학의 독특한 세계관을 ‘확률’이라는 개념으로는 충분히 설명할 수 없다고 판단되며, 이에 화이트헤드의 ‘주체적 지향’개념으로 더 적절하게 설명할 수 있으리라 생각된다.

임진아,최윤아,정미화,강소영,정용재,Lim, Jin-A,Choi, Yun-A,Jung, Mi-Hwa,Kang, So-Yeong,Chung, Yong-Jae 한국문화재보존과학회 2008 보존과학회지 Vol.23 No.-

유기질 문화재 보존 천연 살생물제 개발을 위한 후보물질 조사를 위해 국내 자생하는 11종 수목을 대상으로 각 수목 메탄올 추출물의 9종 목재오염균과 궐련벌레 성충에 대한 항진균 및 살충활성을 조사하였다. 항진균 활성은 목재부후균과 표면오염균에 대해 각각 paper disc soaking 방법과 feeder strip 방법으로 측정되었다. 그 결과, 수목 중 황벽(Phellodendron amurense) 메탄올 추출물은 5 mg/disc에서 Coniophora puteana, Lentinus lepideus, Tyromyces palustris 그리고 Aspergillus niger에 대해 우수한 항균활성을 나타냈다. 또한, 수목 메탄올 추출물의 살충활성은 topical application 방법에 의해 측정되었으며 특히 주목(Taxus cuspidata)과 전나무(Abies holophylla) 메탄올 추출물을 궐련벌레 성충에 25 ${\mu}g$/adult의 농도로 24시간 처리했을 때 56.7%의 치사율을 보였다. 위의 결과로부터 주목과 전나무 그리고 황벽 메탄올 추출물은 각각 충과 목재오염균에 의해 야기되는 생물학적 열화에 대한 유기질 문화재 보존을 위해 유용하게 사용가능할 것으로 사료된다. To investigate bioactive materials for development of natural conservative agent on organic cultural heritage, methanol extracts from 11 wood species which populate in Korea were screened for antifungal and insecticidal activity against 9 wood contaminant fungi and adult of Lasioderma serricorne. Antifungal activity of extracts was tested by using paper disc soaking method and feeder strip test against wood-rot fungi and wood surface contaminant fungi. Among these extracts, the most significant antimicrobial activity was observed from the extract of Phellodendron amurense at 5 mg/disc against Coniophora puteana, Lentinus lepideus, Tyromyces palustris and Aspergillus niger. The insecticidal activity of extracts was examined by topical application against L. serricorne adults. The extracts from Taxus cuspidata and Abies holophylla gave 56.7 % mortality at 25 ${\mu}g$/adult for 24 hr. From these result, the methanol extract from T. cuspidata, A. holophylla and P. amurense described could be useful for conservation of organic cultural heritage against biological deterioration by insect and wood contaminant fungi.

영어 /s/ 인지에 한국인 청자가 사용하는 음향 단서

This study aims to investigate the acoustic cues for the perception of English /s/ in word-initial and word-final positions by Korean listeners. We conducted a perception experiment to find the crucial acoustic cues which determine the mapping between English /s/ and the corresponding Korean loan sounds. The stimuli for the identification experiment were manipulated according to the frication duration of /s/, the prosodic position of /s/, and the stresshood of the syllable containing /s/. Korean listeners listened to each stimulus and identified it as Korean [s] or [s’]. Two main results were found. First, Korean listeners perceive English word-initial /s/ as Korean [s’] regardless of the duration of /s/ when it belongs to a stressed syllable. However, English word-initial /s/ belonging to an unstressed syllable is perceived as either [s] or [s’] depending on /s/ frication duration. Second, the perception of English word-final /s/ is not affected by stress but by the duration of /s/. Perception of English word-final /s/ exhibits a length effect in that English word-final /s/ is perceived differently based on its distance from the word-initial position. The results are discussed in light of prosodic domain strengthening and the relation between speech perception and loanword adaptation.

과정철학의 관점에서 고찰한 아인슈타인의 상대성이론

임진아 한국화이트헤드학회 2012 화이트헤드 연구 Vol.0 No.23

It examined how you could interpret a principle of relativity of Einstein in a concept of the process philosophy of white head. We can get three kinds of conclusions. It is the point that recognized the magnitude of the 'relation' with both for an essential figure naturally first. When it is an element of the true ultimate, Whitehead insists on 'event' and 'actual entity' that it cannot think about itself when it right leaves the meaning significance. Einstein was limited in a physical field, his special theory of relativity tied up the time-space, energy-mass. It went step further and proved that mass (energy) had influence that it could not separate on the time-space in the general theory of relativity. In other words, it can tell you that it is to have formed a structure of the universe that seems to be today through space, energy, an end between the mass of relationships at time. The second, thing about the different point that a relativity concept of Whitehead has with Einstein. It was certain that Einstein recognized the magnitude of relations, but it completely wiped out a thought for 'absoluteness' and was not able to leave. It gave absoluteness to velocity of 'light' in the special theory of relativity and 'mass' in the general theory of relativity. It expanded an extended claim to the area of so-called philosophy (ontology) to speak by insisting on the theory of relativity to have a meaning because white head got away from the limitation called the scientific field called the physics in the magnitude of relations, and all things had relations each other. The third, two people have a difference of the point of view for the substance of nature. Though Einstein recognized the magnitude of relations and completely changed a way of thinking of the universe for the structure of the universe, the substance of nature was not able to get away from what way of thinking that had a material as ever. Whitehead showed a concept innovative (the whole area) to an entity concept in a lifetime. It is 'event' and 'actual entity' immediately. He did a claim that substance was inherent in a different subject. This is the claim that cannot be possibly understood in the concept called continuing substance having a material. 1905년과 1915년에 발표된 아인슈타인의 특수 상대성이론과 일반 상대성이론이 가져온 변혁은 인류가 생각해왔던 시간과 공간에 대해 가지고 있던 사고방식을 완전히 혁신하게 했고, 태초와 우주에 대한 인류의 관점을 완전히 재정립하도록 만들었다. 뉴턴역학에서는 불변하는 기준으로 시간과 공간을 상정해 놓고, 시간과 공간을 무대로 삼아 변화하는 물체에 대한 논의를 하였다면, 아인슈타인은 시간과 공간은 절대적인 기준이 아닌 관찰자에 의해 변화하는 상대적인 개념이라고 말한다. 또한 화이트헤드 역시이 글에서는 첫째, 아인슈타인의 상대성이론에서 말하는 상대성이란 과연 무엇인가를 상세히 살펴본 결과, 아인슈타인의 상대성은 엄밀하게 말하면 ‘상대성’이라 말할 수 없다는 것을 알 수 있다. 그는 ‘절대’개념을 결코 포기하지 않았음을 알 수 있다. 그의 이론에서는 ‘빛’과 ‘질량’이 새로운 절대를 위한 초석으로 등장한다. 둘 째, 아인슈타인의 상대성이론과 화이트헤드의 상대성원리의 관계에 대한 것이다. 화이트헤드의 상대성원리는 존재론적인 영역으로 확장된 것이다. 그러므로 화이트헤드는 아인슈타인의 이론을 충분히 포괄하고 있으며, 나아가 우주의 모든 사물이 존재의 근거 역시 관계성 속에 놓여있음을 역설한다.

Thoreau's Quest in Walden

임진아 현대영미어문학회 2008 현대영미어문학 Vol.26 No.3

Walden is the traces of Thoreau's pilgrimage of a self quest. As a transcendentalist, he had belief in inner light and an inner self of man. Thoreau believed that the answer to seek the center of the self is in simplicity. Resisting confining his belief only in the theory, by isolating himself to the woods and simplifying the life to its least necessities, he willingly took a journey of a pilgrim to himself - to his unknown self, to the inner light of self - and put his faith into practice himself. Despite the humble and simple days in Walden, nearest to the core of nature and freest from the heavy garments of life, his life was not static at all. Rather it was very active and continually progressive, getting closer to spiritual full awakening. In Walden, he felt his inner self gazing at the deep pond, experienced the cycles of life and its stages through the four seasons, and got reawakened by the thaw. Finally in spring, he came out from darkness to light reborn, to the light of the self. And in Walden, by showing how to live and how to get to purification and rebirth, Thoreau urged us to be a Columbus of our own selves.

This study examines the impact of university graduate Startup rates on economic growth in the regions where universities are located, using panel data from 35 universities in 17 regions in Korea and 21 universities in 13 cities in China over a six-year period from 2016 to 2021. In Korea, a total of 35 universities were selected as part of the Ministry of Education's "University-initiated Startup" policy, including Startup-oriented universities, leading universities in Startup education innovation, Startup education bases, and excellent universities in Startup education, while in China, 21 universities were selected as part of the pilot bases established as part of the "Mass Entrepreneurship, Mass Innovation" policy. To analyze the economic impact of the universities on the regions where they are located, we aimed to conduct an empirical analysis of the economic impact using economic indicators of the economic growth rate of the regions where they are located. The results of the empirical analysis show that the Startup rate of university graduates in Korea and China both have a positive impact on the regional economic growth rate, but the Startup rate of local university graduates in Korea has a greater impact on the regional economy than in China. Based on the findings that the number of entrepreneurs produced by universities has a positive impact on the economic growth of their regions, this study draws implications for the role of universities and regions in revitalizing local economies and the establishment of systems to resolve the imbalance between metropolitan and non-metropolitan areas.
