This study examines the status and the physical features of Paraloid B-72 layers with examination of microstructure and analysis of organic matters. Paraloid B-72 layers were coated on samples from the colour layer of outer wall painting in Mireuk hall in Geumsan temple. On the basis of the previous examination result, it has made the samples which are similar to outer wall in Mireuk hall in Geumsan temple. The samples can be divided into two, one; 5% Paraloid B-72 coating and another is without coating. Then samples have been experimented under the compulsive environments of infrared radiation and immersion, thereafter compared the results of the damages and physical features between two samples. As a result of the comparison, the sample with Paraloid B-72 had more serious cracks, exfoliations and peeling layers than that of without Paraloid B-72. Otherwise, in the examination of ultraviolet radiation, the sample with Paraloid B-72 coating showed weaker physical properties, less density in structure of colour layer and less hardness in surface of colour layer than the sample without coating. The percentage of moisture content after the ultraviolet radiation was higher in the sample without Paraloid B-72 than the sample with Paraloid B-72 coating. Observing the conditions before the ultraviolet radiation, the sample with Paraloid B-72 coating demonstrated lower rate in moisture evaporation rate than the sample without Paraloid B-72. As a consequence, in examination of this samples, the change of physical features are increased in the sample with Paraloid B-72 coating than that without Paraloid B-72 when compulsive environment of heat, moisture and ultraviolet rays for a short term are imposed.

'Griffis Collection' is a collection of photographs of Japan and Korea in modern era, collected by William Elliot Griffis. Originally Mr. Griffis was studying about Japan when he developed an interest on Korea, and started to collect helpful materials he could find to study. Later days of Griffis' life, he donated his research to Rutgers University Library, and those materials were named and preserved as Griffis Collection. This paper is about photographs that illustrate modern Incheon and Hansung, and study them in order to discover how Korea's modern cities and architecture were formed and built. In total, there is four categorized chapters of photographs, and those are cities, public buildings, educational facilities and private buildings. In Griffis Collection, there are 23 photos those are relate to this paper's subject, but only 19 of them that has historic value has been covered in this paper. In results, all 19 photos were proved that they have significant information in terms of historic research of modern Korea and Korea's modern architectural stages.

볼라뇨의 <참을 수 없는 가우초>: 보르헤스의 <남부> 다시쓰기

이경민 ( Kyeong Min Lee ) 한국스페인어문학회 2013 스페인어문학 Vol.0 No.68

Una de las caracteristicas mas relevantes de la estrategia narrativa de Roberto Bolano es la reescritura transformacional basada en la intertextualidad con diversas obras anteriores. No cabe la menor duda de que “El gaucho insufrible” de Roberto Bolano como un cuento parodico de “El Sur” de Borges no esta fuera de esa forma de escritura. Tambien es de mencionar que el cuento tiene ciertos vinculos textuales con las obras como, sobre todo, “El evangelio segun Marcos” de Borges, “Carta a una senorita en Paris” de Cortazar y “Triptico zoo-botanico con rasgos de improbable erudicion” y “Aballay” de Di Benedetto, por los cuales pareceria un texto rizomatico o un juego intertextual de una multiplicidad de voces referenciales. Lo que no se debe perder, entre tanto, es que mientras que “El Sur” vislumbra la vision que tiene Borges del discurso de la civilizacion y barbarie, Bolano tiene de objeto “El Sur” para reescribirlo y desmitificarlo. Este trabajo, partiendo desde esta perspectiva, realiza por dos lados, uno por la forma y el otro del discurso que tienen ambos textos, un acercamiento al punto que llega la reescritura de Bolano a Borges.

탄소나노튜브/그래핀 나노플레이트릿 강화 에폭시 복합재의 열적 및 기계적 특성에 미치는 불소화의 영향

이경민(Kyeong Min Lee),이시은(Si-Eun Lee),이영석(Young-Seak Lee) 한국고분자학회 2016 폴리머 Vol.40 No.4

에폭시 수지와의 계면 결합력을 향상시키기 위하여, 탄소나노튜브(CNT)와 그래핀 나노플레이트릿(GNP)을 불소화시켰다. 표면 처리된 CNT와 GNP의 표면화학적 특성은 광전자 분광기를 이용하여 분석되었다. 또한 그 에폭시 복합재의 기계적 성질 및 열안정성을 평가하였다. CNT와 GNP 보강 에폭시 복합재는 CNT 보강 에폭시 복합재와 비교하여 비교적 높은 강도를 보였다. 이러한 결과는 종횡비가 서로 다른 두 강화재 때문에 네트워크 구조가 형성되어 나타나는 크기효과에 기인하였다. 불소화 표면처리된 CNT/GNP 보강 에폭시 복합재의 인장강도, 충격강도 및 열안정성은 미첨가 에폭시와 비교하여 각각 101, 69, 및 130%로 크게 향상되었다. 이 결과는 크기 효과 및 표면 처리에 따른 강화재와 에폭시 수지의 계면 결합력 향상에 의한 시너지 효과에 기인한 것으로 보인다. To improve interfacial interaction with the epoxy resin, carbon nanotube (CNT) and graphene nanoplatelet (GNP) are fluorinated. A surface-chemical property of the surface-treated CNT and GNP has been analyzed by X-ray photoelectron microscopy (XPS). Then the mechanical properties and thermal stabilities of composites which are reinforced by them are also evaluated. The mechanical properties of CNT/GNP reinforced epoxy composites are comparatively higher than those of epoxy composites reinforced with CNT only. These results are attributed to a size effect resulted from the network structures due to different aspect ratios of reinforcement. The tensile, impact strength, and thermal stability of the composites including fluorinated CNT and GNP are remarkably increased by 101, 69, and 130% compared to those of neat epoxy, respectively. These results are attributed to the synergy effect of the size effect and improvement of interfacial interaction between surface-treated reinforcements and epoxy resin.

「엠마 순스」, 『죽음과 소녀』, 「살인 창녀들」에 나타난 여성 복수극의 양상

This work focuses on analyzing three works, “Emma Zunz” by Jorge Luis Borges, La muerte y la doncella by Ariel Dorfman and “Putas asesinas” by Roberto Bolaño. Undoubtedly. These three works, forming a narrative similarity, are motivated by the history of Judith. Borges, taking advantage of the narrative structure of Judith and inverting the logic of cause and effect, distorts the codes of the detective novel. In La muerte y la doncella, Ariel Dorfman, also using Judith's story, problematizes Chilean history through the memory of a woman who seeks the truth. Finally, Roberto Bolaño, through a woman who kidnaps a man and tries to murder him after having a sexual relationship, radically criticizes the androcentric world. Although the three works have different ways of narrating, they start from the story of Judith in common. This clearly shows that rewriting or parody is one of the fundamental features of writing.

멕시코인의 정체성과 죽음 -룰포의 「날 죽이지 말라고 말해줘」와 푸엔떼스의 「착몰」을 중심으로-

이경민 ( Lee Kyeong-min ) 한국스페인어문학회(구 한국서어서문학회) 2020 스페인어문학 Vol.0 No.94

This work investigates the two works, Juan Rulfo’s “Diles que no me maten” and Carlos Fuentes’s “Chac Mool”, through the term of death. Reger Bartra understands that the indifference to death was invented by Mexican intellectuals. It means that the indifference to death is the result of the intellectuals' project to create a national hero at the time of nation-state formation. Then it is necessary to observe that the Mexican writers how they contributed to that project. So, this work tries to observe how death works in the Mexican narrative, especially in the works of Juan Rulfo and Carlos Fuentes. This work observes that both works are related to Mexican cultural identity. “Diles que no me maten”, through death as a metaphor for Mexican history would be a desperate message that longs for no more death. “Chac Mool” would be the expression that Mexican identity comes from pre-Hispanic history and the present and the past are complementary to Mexican history.

에폭시 복합재의 물성을 향상시키기 위하여, 일라이트 및 탄소나노튜브가 불소 가스로 표면처리 되었다. 불소화 처리된 일라이트 및 탄소나노튜브는 엑스선 광전자 분광기를 이용하여 분석하였고, 그 복합재의 기계적 및 열적 특성을 평가하였다. 이 에폭시 복합재는 미첨가 에폭시 복합재와 비교하여 인장강도는 약 59%, 충격강도는 18%, 열안정성은 124%로 크게 향상됨을 확인하였다. 에폭시 복합재의 기계적 및 열적 특성의 향상은 일라이트 및 탄소나노튜브의 불소화가 에폭시 내에서 분산성을 향상시키고 에폭시 수지와의 계면 결합력을 증가시켰기 때문이다. To improve properties of epoxy composites, surfaces of the illite and carbon nanotube (CNT) were treated by fluorine gas. The fluorinated illite and CNT were then characterized by X-ray photoelectron microscopy (XPS) and the mechanical and thermal properties of their composites were evaluated. The tensile and impact strengths and thermal stability of the composites increased upto about 59%, 18% and 124%, respectively compared to those of the neat epoxy. Improvements of mechanical and thermal properties in the composites were attributed that the fluorination of illite and carbon nanotube helps to enhance the dispersion in epoxy resin and interfacial interaction between them.
