목 적：본 연구는 청소년의 자살성향과 관련된 정서적 특성을 지역사회연구를 통하여 조사함과 아울러 우울불안 집단을 설정하여 그들의 충동성과 자살사고를 알아보고자 하였다. 방 법：경기도 고양시의 1909명의 중·고등학생들을 대상으로 Center for Epidemiologic Study for Depression(CES-D), Revised Children's Manifest Anxiety Scale(RCMAS), Youth Self Report(YSR)의 Anxious/Depressed subscale을 사용하여 우울불안집단을 선정하였고, 대조집단과 비교하여 PS-1 of Offer's Self Image Questionnaire(PS-1 of OSIQ), Suicide Ideation Questionnaire(SIQ) 척도점수를 측정하였다. 또한 자살사고와 관련된 정서적 요인들과의 상관성 및 자살사고 예측력을 분석하였다. 결 과：우울불안집단을 연구대상의 6.58%를 차지하였으며 남녀비는 약 1:1.5이었다. 또한 우울불안집단에서 대조집단에 비하여 충동성조절 점수는 유의하게 높았고 자살사고 척도 점수도 유의하게 높았다. 자살사고와 관련하여 우울척도, 불안척도, 우울-불안척도 및 자살사고 척도는 모두 유의한 상관성을 보인 요인들이었으며, 다중회귀분석 결과 우울과 불안이 자살사고를 예측하는 유의한 요인이었다. 결 론：지역사회 청소년들을 대상으로 자살사고의 정서적 요인들 조사한 결과 우울 및 불안성향을 지닌 집단이 자살의 고위험군임을 시사하였으며, 이를 위한 예방적 개입이 중요함을 알 수 있었다.

In this study, source criticism (an establishment of authentic text) of the Hyun-Mu Sutra(玄武經) among different editions is studied and an attempt of a new interpretation appropriate to that is attempted. The Hyun-Mu Sutra, a scripture written in 1909, began to communicate with the world through the religions of Jeungsanism. In particular, it was remarkable that The Hyun-Mu Sutra was absorbed as canon textbooks Jeonkyung(典經), the Scriptures of Daesoonjinrihoe, The Fellowship of Daesoon Truth(大巡眞理) from a loner and secret pull-out of heritage traditions. However, this scripture though written in 1909 and more than 100 years has passed, remained in a state unestablished authentic text. The Hyun-Mu Sutra is the scripture consisted of 25 pages by the religions of Jeungsanism[Gang Il-sun 姜一淳(1871~1909)]. 33 page type of Hyun-Mu Sutra has been distributed in the world until now the authentic text of The Hyun-Mu Sutra. However, as a result of the examination, diagnostic scripture(病勢文) was found to have been added by descendants. After a review of authentic text of The Hyun-Mu Sutra, it concluded that there is no diagnostic scripture in primary The Hyun-Mu Sutra. Though The Hyun-Mu Sutra is a booklet of a small amount, the notation and expression is so unique, it has been in secrecy to read its contents. Interpretation way of The Hyun-Mu Sutra up to now can be summarized in two as follows. 1) approaches by I-ching 2) approaches by ten celestrial stemps and twelve earthly branches(10干12支). Approaches by I-ching among this sometimes was supplemented with Buddhist classification methods. Nevertheless, these studies can be evaluated limited because it fails to secure authentic text of The Hyun-Mu Sutra. In this study, the contents of The Hyun-Mu Sutra was examined itemized by focusing on the following four points. 1) The icon of The Hyun-Mu Sutra(玄武經符) is similar as normal talisman(符籍) but it has other features. 2) 'Reverse Fonts'(反書體)[the opposite view of the standard fonts(正書體), reflected in the mirror fonts] and size or location used in text is not in uniform. 3) letters in scripture were pointed and points were stamped in the left and upper and lower characters. 4) "Spiritual poem" (詠歌, the Korean traditional music with a view of elegance as an origin of eco), and the music with the Five-Sounds[宮Gung, 商Sang, 角Gak, 徵Chi, 羽Wu) were related. As a result, content analysis of The Hyun-Mu Sutra is carried out in the next four points. 1) The icon of The Hyun-Mu Sutra (玄武經符) has been primarily developed by Jeungsan. 2) 'Reverse Fonts'(反書體)[the opposite view of the standard fonts(正書體), reflected in the mirror fonts] and reverse location such as '宙宇' [the reverse of '宇宙'] represents based on a new world based on a forward and reverse I-ching(正易). 3) Dot and neighbor points is a symbolic map that guides the position of lateral new world(後天) and era(人尊) 4) Spiritual poem is the entrance to achieve the Realization of Do(道通). The above can be considered as the results of this study.

This paper is a sequel to [26]. We investigate how the Axiom of Choice has been accepted after Zermelo introduced the Axiom in 1904. The response to the Axiom has divided into two groups of mathematicians, namely idealists and empiricists. We also investigate how the Zorn's lemma (1935) has been emerged. It was originally formulated by Hausdorff in 1909 and then by many other mathematicians independently.

In the paper, the authors find a common solution to three series of differential equations related to the generating function of the Bernoulli numbers of the second kind and present a recurrence relation, an explicit formula in terms of the Stirling numbers of the first kind, and a determinantal expression for the Bernoulli numbers of the second kind.

Three harpacticoid copepods, Dactylopodamphiascopsis latifolius (Sars, 1909), Diosaccus ezoensis Ito, 1974 and Ambunguipes rufocincta (Brady, 1880) are recorded as new to the Korean fauna with illustrations, on the basis of the specimens collected mainly from the marine macro algae during the period from June 1990 to September 1997.

알미늄이 경제적인 금속으로서 자리를 차지하게 된것은 70년 이내이며 이것이 약 60여년전에 가공전선으로 사용되면서 부터 전기부문에서 매우 중요시되었다. 그리고 매설케이블로서는 약 50년전에 고안되었으며 1909-1913년 사이에 불영간 320km이상이 포설되어 아직도 이들의 대부분이 사용되고 있다. 알미늄의 정상적 이용은 1934년 독일에서 시작하였으며 영국에 있어서는 제2차 세계대전후 전기공업부문에서 위치를 차지하게 되었다. 알미늄 생산 증가율은 발전량 증가율보다 클 뿐더러 다른 일반 비철금속의 생산 증가율은 이에 따르지 못하고 있다. 즉 1930-1953년 사이에 전 세계 전력개발은 160%증가함에 따라 동의 증가는 불과 25%인데 반해서 알미늄은 300%를 나타내고 있다.

This thesis, based on the semiotic theory, compared the meaning of sign which is a grounding the military uniform of the category of clothings as a cultural sign for formative relation. As for the scope of study, I made the Amy's uniforms during the last period of Korea Empire from 1895 to 1909 as an object of amy thesis and analyzed their decument and photographes. As a result of analyse of military uniform during by semiotical application, I made clear that it has role of signal by underlying signal's aspect of sign, and it si a sign which could symbolize the class, national and periodical distinction.

노벨상에 기술상이나 공학상은 아직 없다. 그러나 기술자도 노벨과학상을 수상한 예가 초창기엔 더러 있었다.1909년 무선통신발명으로 물리학상을 받은 마르코니 등 그리고 X선을 발견한 독일의 뢴트겐, 전기기사였던 퀴리부인의 사위 프레드릭퀴리 등 다수가 공과계였다 .또1차 과학혁명을 일으킨 갈릴레오나 뉴턴은 망원경을 제작하거나 발명하는 등 기술능력을 보여주었다. 우리도 과학기술 교육의 혁식으로 노벨상수상의 꿈을 이루어야 하겠다.

We propose in this paper a companding scheme or peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. By exploiting statistical distribution of OFDM transmit signals, the proposed scheme effectively reduces the PAPR by compressing the peak signals, while maintaining the average power unchanged. Simulation results are provided to show good performance of the proposed scheme.
