  • The systematic position of Cymopterus melanotiligia (H. Boissieu) C. Y. Yoon in Apiaceae was revaluated based on the ITS sequence data. Its diagnostic characteristics include its asymmerty mericarps, 3-4 mericarp ribs, winged dorsal ribs, and ternate leaves. It is morphologically similar to Tilingia tsusimensis and Pimpinella having ternate leaves. It is distinguished from Ostericum having symmerty mericarps, 5 mericarp ribs, and rounded dorsal ribs. Also it looks like Angelica with broadly winged lateral ribs and strongly dorsally compressed mericarps, but is distinguished by having its conspicuous calyx teeth and unilayer pericarps. Cymopterus melanotiligia formed a different clade group with Cymopterus species distributed in North America based on ITS sequences, and it supports the close relationships with Halosciastrum melanotilingia. Thus, we conclude that this species is here referred to Halosciastrum melanotilingia (H. Boissieu) Pimenov & Tikhomirov.

  • 아리스토텔레스의 논리학은 그 도구적, 방법론적 성격 때문에 보통 "organon"이라고 불린다. 많은 아리스토텔레스 연구자들은, 그의 논리학 이론들이 그가 손댄 여러 분야의 연구에서 정밀 도구 구실을 하는지를 밝히는 데 몰두해 왔다. 지난 30년 넘는 세월 동안 아리스토텔레스 연구를 이 끌어왔던 논의 가운데 하나인, "genos"와 "eidos"의 쓰임에 논의도 바로 그런 연구 전통에 잇닿아 있다. 이 논의는 요즘 일단락된 것으로 받아들여지고 있다. 아리스토텔레스의 논리학에 나오는, 게노스와 에이도스에 의한 분류는 그의 생물학 연구에서는 별 가치가 없다는 것이 일반적인 의견이다. 생물학 연구에서는 문제의 두 개념이 논리학에서처럼 "유"와 "종"의 뜻으로 쓰이는 것이 아니라 상대적인 개념으로 쓰이며, 그렇기 때문에 생물 분류와 무관하다는 말이다. 하지만 문제의 두 개념들이 등장하는 구절들을 문헌학적인 방법을 써서 분석해 보면, 이런 일반적인 의견은 별 근거가 없는 것으로 드러난다: 생물학에서 eidos는 개별자들을 포함하는 종을 가리키는 개념으로, 절대적으로 쓰인다. genos의 경우는 그 쓰임이 좀 더 복잡하지만, 아리스토텔레스가 생물학에서 내세우는 생물의 형태론적 구 분과 관련해서 쓰일 때는 언제나 "유"를 뜻한다. 그런 점에서 genos와 eidos는 본질적으로 생물 분류에 쓰인 개념들이다. 이런 사실은 곧 아리스토텔레스의 논리학이 그의 생물학 연구에서 유용한 도구로서 쓰임을 보여주는 하나의 증거이다.

  • As the boundaries between disciplines have been weakened and interdisciplinary or multidisciplinary subjects have increased, there is a limitation to express subjects with DDC. This study evaluates DDC instructions using interdisciplinary numbers and classifying more than one discipline through Delphi research. As a result, it is found that there is a need for defining separately 'interdisciplinary subjects' and 'multidisciplinary subjects', based on the level of integration among disciplines, and improving the instruction to maintain the consistency in assigning and filing classification numbers. It is also discussed that to enhance the symbols' power of expression, an analytic/synthetic method could be adopted.

  • Dwarf bamboo(Sasa borealis) is a dominant understory species in the various forest types in Korea. The objective of this study was to investigate vegetation structure of Sasa borealis and effects of Sasa on the growth of overstory tree species along the forest development after clearcutting. Three representative stand types with and without S. borealis in Baekwoonsan, Chonnam province were selected in 1998 for this study: uncutting stands(natural deciduous forests with overstory vegetation), 1987-cutting stands (11 years after clearcutting), and 1993-cutting stands(5 years after clearcuting). Vegetation type was largely classified into Sasa borealis dominant type and Sasa borealis recessive or absent type. The former composed of four associations including Quercus serrata-Carpinus laxiflora / Sasa borealis community, Cornus controversa-Morus bombysis / Sasa borealis community, Styrax japonica-Styrax obassia / Sasa borealis association, Zelkova serrata / Sasa borealis community. The latter divided into six associations including Quercus serrata / Lindera erythrocarpa community, Cornus controversa / Lindera erythrocarpa community, Quercus serrata / Acer pseudosieboldianum / Deutzia glabrata community, Fraxinus rhynchophylla-Quercus serrata / Lindera erythrocarpa / Euonymus alataus community, Rubus crataegifolius-Hydrangea macrophylla community, Rubus crataegifolius-Lespedeza bicolor community. Distribution of Sasa, borealis by developmental stages of forests showed that in natural stands was dominant understory, but was various pattern in two cutting stands. Mean annual ring growth of Quercus serrata and Carpinus laxiflora during the last 35 years had not been affected by presence of Sasa, based on comparisons in annual ring growth between Sasa-present and Sasa-absent stands. In conclusion, dense crown of Sasa borealis suppressed the invasion of other shrubs or annuals and facilitated later stages of plant succession by promoting growth of shade-tolerant tree species after clear cutting.

  • 풍수는 그동안 한국의 전통적인 지리학, 지리사상 또는 환경관 등으로 이해되어 왔다. 특히 그것은 거시적, 미시적 차원의 제 입지요소를 고려하는 전통적 입지론 또는 공간배치의 원리로서 제 학문분과에서의 그 현대적 수용가능성과 관련하여 주목받고 있는 것도 사실이다. 그런데, 지표상의 제 지리적 현상 중 특히 역사적 경관이나 장소 등에 관심 갖는 현대지리학의 입장에서 그것의 풍수와의 관련성을 배제할 수 없다고 할 때, 자칫 신비의 범주로 분류되곤 하는 풍수를 어떻게 관련지을 수 있는가의 문제는 그렇게 간단한 것이 아니다.

  • The present study aims to verify the usefulness of microcurrent stimulation as an effective intervention for managing body shape. Thirty female college students with a percentage body fat of 30% or more participated as subjects and belonged to the one of three groups; control group, combined exercise group, microcurrent stimulation group. Based on the results of analyzing the measurement data from pre- and post-intervention for four weeks for each group, the following conclusions were obtained. There was no statistically significant difference in all measured variables in the control group. However, waist circumference and TC were significantly reduced in the combined exercise group, and also weight, percentage body fat, waist circumference, and apolipoprotein were significantly reduced in microcurrent stimulation group. Considering the above conclusions, it can be suggested that microcurrent stimulation could be an effective intervention to improve body composition and blood lipid profile to have a healthy body.

  • 본 연구는 뇌의 편측 영역 에서의 EEG(Electroencephalography) coherence 로 손동작 의도를 예측하고자 하는 연구이다. 손 동작 예측을 위한 실험에 신체에 이상이 없는 6 명의 피실험자가 참여 하였다. 실험은 데이터 트레이닝 6 분과 동작 의도 판단 6 분으로 진행되었으며 무작위 순서로 손 동작을 지시한 후 편측적 영역 5 개 지점의 EEG 와 동작 시점을 알기 위한 오른손 EMG(Electromyography)를 측정하였다. 측정된 EEG 데이터를 분석하기 위해 주파수 별 Alpha 와 Beta 를 분류하였고 EMG 신호를 기준으로 동작과 휴식으로 분류된 Alpha 와 Beta 데이터를 5 개의 측정 영역별 Coherence 분석을 하였다. 그 결과 동작과 휴식을 구분할 수 있는 통계적으로 유효한 EEG Coherence 영역을 통하여 동작 판단을 할 수 있음을 확인하였다.

  • This study intends to analyze the library classification of agriculture in DDC, from the Int edition to the 21th edition. Since Dewey Decimal Classification(DDC) was the first published in 1876, number of total items increased significantly a newly-organized and subdivision of them in the 8th, 10th and 12th edition. According as the discipline developed and was specialized, the agricultural division in DDC was fractionized, and new subjects were continuously added to it. After that time the first edition, the major changes arranged an class and order in the 15th and 17th edition. That is to say, ‘Farm economics’ in 631.1 was relocated to 338.1 in the 17th and ‘Veterinary sciences’ in 619 was relocated to 636.089 in the 15th. Especially, up to now ‘Farm Economics’ deals with an important branch in the science of agriculture. Here the matter of argue heatedly arranges it from economics to agriculture.

  • It was revaluated about taxonomical position of the Tilingia tsusimensis (Yabe) Kitagawa (Apiaceae) collected from Mt. Gaya, Mt. Geumo, and Mt. Songni in Korea. Its diagnostic features include slightly dorsally compressed mericarps, acute-prominent ribs, ternate leaves, and dimorphic white petals. It is morphologically similar to Cymopterus and Pimpinella in having ternate leaves. It is distinguished from Cymopterus having asymmerty mericarps, 3-4 mericarp ribs, and winged dorsal ribs. Pimpinella differs in having slightly laterally compressed mericarps without ribs and conspicuous calyx teeth. Also, it looks like Angelica with obsolete calyx teeth and multilayer pericarps, but is distinguished by having its broadly winged lateral ribs and strongly dorsally compressed mericarps. Tilingia tsusimensis formed a monophyletic clade or sister group relationship with a genus Angelica based on ITS sequences. Based on the above observations, we conclude that this plant is here referred to T. tsusimensis (Yabe) Kitagawa.
