        제주도 지하수 질산염 농도의 시·공간적 변화 특성: 장기(1993-2015) 모니터링 자료의 평가

        김호림(Ho-Rim Kim),오준섭(Junseop Oh),도현권(Hyun-Kwon Do),이경진(Kyung-Jin Lee),현익현(Ik-Hyun Hyun),오상실(Sang-Sil Oh),감상규(Sang-Kyu Kam),윤성택(Seong-Taek Yun) 대한자원환경지질학회 2018 자원환경지질 Vol.51 No.1

        1993년부터 2015년까지 관측된 제주도 지하수 장기모니터링 관측정(N = 4,835)에서 수집된 지하수 수질자료(N = 21,568)를 기반으로 질산성질소의 시공간적 변동 특성을 평가하였다. 제주도 지하수의 질산성질소 농도의 중앙값은 2.5 mg/L로서 다른 국가나 대륙의 조사 결과에 비해 다소 높거나 유사한 것으로 나타났다. 또한 지하수 용도, 행정구역 및 고도 별로 유의한 차이를 보였다. 특히, 산간 지역에 비해 저지대 해안가에 위치한 농업 및 주거지역에서 농도가 높음을 확인하였다. Mann-Kendall 및 Sen’s slope 분석을 활용한 질산성질소 농도의 추세 분석 결과, 하류 저지 대에 비해 중산간지역에서의 질산성질소 농도 증가 경향이 뚜렷하였다. 제주도 내 토지 피복의 시계열 변화 특성과 결부 지어 보면, 중산간지역의 오염 증가 추세는 농업지역의 확장 등 인위적 활동 증가에 기인한 결과로 판단된다. 반면,기지정된 지하수자원특별관리구역에서는 전반적으로 질산성질소 농도의 감소 경향이 나타났는데, 이는 지하수 관리 측면에서 수질관리를 위한 적극적인 정책이 유효함을 시사한다. 본 연구에서는 제주도 지하수의 질산성질소 오염관리를 위한 적정 방안을 제안한다. The spatio-temporal variations of nitrate concentrations in groundwater of Jeju Island were evaluated by an analysis of time series groundwater quality data (N = 21,568) that were collected from regional groundwater monitoring (number of wells = 4,835) for up to 20 years between 1993 and 2015. The median concentration of NO 3 -N is 2.5 mg/L, which is slightly higher than those reported from regional surveys in other countries. Nitrate concentrations of groundwater in wells tend to significantly vary according to different water usage (of the well), administrative districts, and topographic elevations: nitrate level is higher in low-lying agricultural and residential areas than those in high mountainous areas. The Mann-Kendall trend test and Sen’s slope analysis show that nitrate concentration in mid-mountainous areas tends to increase, possibly due to the expansion of agricultural areas toward highland. On the other hand, nitrate concentrations in the Specially Designated Groundwater Quality Protection Zones show the temporally decreasing trend, which implies the efficiency of groundwater management actions in Jeju. Proper measures for sustainable groundwater quality management are suggested in this study.

      • 초·중등학교에서의 세계문학 교육 : 현황 및 제안

        권오현 한국헤세학회 2003 헤세연구 Vol.10 No.-

        In dem vorliegenden Aufsatz wird versucht, die gegenwartige Situation des Unterrichts der Weltliteratur an koreanischen Schulen genauer darzustellen und aus literaturdidaktischer Sicht Ansatze zu einer Verbesserung aufzuzeigen. Wahrend der ersten vier Schuljahre in der Grundschule erscheinen auslandische Literaturwerke zwar nicht im Lehrplan, aber in den Lehrbuchern fur die funften und sechsten Klassen stehen verschiedene Werke der Weltliteratur, besonders Marchen und Kinderliteratur. Die Sozialisation der Kinder durch die Literatur durfte hier im Mittelpunkt des didaktischen Interesses stehen. Bei den fur die Lehrbucher der Mittelschule ausgewa hlten Werken wird besonderer Wert auf die Vermittlung der Universalitat des menschlichen Lebens gelegt. Der Schwerpunkt liegt dabei auf der Erziehung der Jugendlichen zu einem verantwortungsbewußten Leben. Die handelnden Personen in den einzelnen literarischen Werken konnen hierbei eine Vorbildfunktion ausuben. Der Literaturunterricht der elften und zwolften Klassen bietet wahrend der Schulzeit den umfangreichsten Rahmen fur die Vermittlung der Weltliteratur. In jedem Lehrbuch stehen durchschnittlich 12,7 Werke der Weltliteratur(13% Pro Lehrbuch). Angesichts der Tatsache, daß die Kultur in den Landern der dritten Welt mit immer starker werdendem Selbstbewußtsein hervortritt und ein eigenes Gesicht entwickelt, erscheint es sinnvoll, daß wir die Vorstellung von der geistigen Hegemonie einzelner Literaturen uberwinden und den neuen Realitaten Rechnung tragen. Als Resultat der veranderten Betrachtungsweise wurde ab den neunziger Jahren das Kapitel ‘Koreanische Literatur innerhalb der Weltliteratur’ als eigenstandiger Abschnitt in die ‘Literatur’-Schulbucher aufgenommen. In diesem Abschnitt soll die Entwicklung der koreanischen Literatur innerhalb der Weltliteratur erklart werden; auch sollen den Schulern Verbindungen zwischen den einzelnen Literaturen verdeutlicht werden. Die ausla ndische Literatur existiert also in Bezug zur koreanischen Literatur. Aber ohne ein Interesse fur das andere Wesen kann keine echte Beziehung entstehen, weil ‘Beziehung’ die ontologische Verbindung zweier Wesen meint, Die Weltliteratur ist ‘das Andere’, das die dialektische Entwicklung der koreanischen Literatur befordert. Um der koreanischen Literatur einen festen Platz in der Weltliteratur zu sichern, bedarf es des Verstandnisses fur die ausla ndische Literatur an sich. Wenn Weltliteratur nicht als selbststandiger Gegenstand, sondern nur in Beziehung zur koreanischen Literatur untersucht wird, ist dies nicht forderlich fur die Globalisierung der koreanischen Literatur.

        탈식민의 과제와 한국의 국사 교과서

        권오현 역사교육학회 2005 역사교육논집 Vol.34 No.-

        The purpose of this study is to analyze how to describe the periods under the Japanese imperialistic rule in Korean History textbook by the viewpoint of the post-colonialism. In this study, all the korean history textbooks were analyzed. In result, the problems to be pointed out are the followings; (1) the emancipation fromthe suppressed memories about painful experiences of the Japanese imperialistic rule, (2) the liquidation of vestiges of Japanese imperialism, (3) the restoration of all the independence movements in defiance of Japanese coercion, (4) the internalizing colonialism and the attacks against the weak(=women, foreigners, the poor, the underprivileged, etc.) by the colonized Koreans, (5) the reconstruction and restoration of the trivial round of daily life, (6) the accomplishment of the harmony between nationalism and post-colonialism. These are problems to be corrected rapidly.

        For the isolation of mycobacteria in sputum specimens, it is essential to use the most gentle procedure of digestion system for the survival of organisms. The present studies were undertaken to evaluate and compare the effect of various sputum digestants on the death of Mycobacterium fortuitum and Mycobacterium tuberculosis. The results were summarized as follows: 1. Death rates of M. tuberculosis in a solution of 2% NaOH, 3% NaOH and 4% NaOH digestants after 30 minutes of contact time were 97.1%, 97.6% and 97.9%, respectively. In the digestants of 2% NaOH, 3% NaOH and 4% NaOH solution after 1 hour of contact time, survival rates were less than 2%. 2. Death rates of M. tuberculosis in Zephiran-N-acetyl-L-cysteine digestant after 30 and 60 minutes of contact time were 28.5% and 39.5%, while those of M. fortuitum after the contact time were 74.1% and 81.2%, respectively. 3. Death rates of M. tuberculosis in Zephiran-trisodium phosphate digestant after 30 and 60 minutes of contact time were 36.1% and 40.3%, and those of M. fortuitum after the contact time were 71.6% and 74.2%, respectively. 4. Death rates of M. tuberculosis and M. fortuitum in N-acetyl-L-cysteine-NaOH (2%) digestant were similar to the digestant of 2% NaOH solution.

      • 矯正用 接着劑의 引張强度

        權五源,成在鉉 慶北大學校 齒科大學 1984 慶北齒大論文集 Vol.1 No.1

        The requirement of ideal orthodontic direct-bonding adhesive should include longevity of bond, ability to withstand a variety of forces, resistance to the degrading effects of the oral environment, and ability to be easily removed without affecting the integrity of the enamel. The purpose of this study was to evaluate the adhesive properties of recently developed 3 orthodontic direct bonding adhesives by testing the tensile strength. 75 premolars extracted for orthodontic treatment were used. The tensile strength was tested by Tensilon/UTM-1-10000C after 24 hours from bonding. Following results were obtained; The mean tensile strength of each product was higher than the maximum force(29㎏/㎝) exerted on a bracket during orthodontic treatment. The tensile strength of Mono­Lok was statistically higher than Concise and Dyna­Bond, although there was no difference the tensile strength of Concise and Dyna­Bond statistically. Of the failure, the combination type of failure(68%), where part of the adhesive remained on the tooth and part of the bracket was the most common type. The second type of failure (22.7%) occurred at the tooth­adhesive interface and the last type of failure (9.3%) occurred at the adhesive­bracket interface.

        權五鉉 영남이공대학 1997 論文集 Vol.26 No.-

        The thermographic survey using thermal imager is considered to be a method detecting the surface temparature differences between the delaminated area and the sound area of finishing materials on building walls. So, there exist some analytical studies using heat balace simulation on this method However the numerical results obtained by a heat balance simulation can not always represent the easiness of judgement. In this study, the availability of the simulated thermal images using finite element method with smoothing technique are discussed by comparing with the thermal images of test specimens and for application example. to detect the steel-bar of reinforced concrete structure is tested.
