To investigate the alleviative effects of Cnidium officinale water extract (COWE) on inflammation and skin barrier damage, both the irradiation of UVB and the application of squalene monohydroperoxide (Sq-OOH) to the backs of hairless mice were performed for 4 weeks. And at the same time experimental materials were applied topically. The skin erythema indices for the positive control (PC, 0.01% retinoic acid) and experimental (E, COWE) groups were lower than that of the control (C) group. Whereas both the lipid and water capacities for the PC and E groups were higher than those of the C group. Epidermis and dermis of the C group were remarkably thickened in comparison with the PC and E groups. Relatively much less number of inflammatory cells, including lymphocytes and neutrophils were found in dermis of the PC and E groups compared with the C group. Lipid lamellae of the C group were broken severely, showing an irregular arrangement and lipid content was much reduced. Whereas those of the PC and E groups were almost intact with a regular arrangement, that were similar to that of the N group. Taken the results all together, it was confirmed that COWE could be effective natural herbal material for the alleviation of inflammation and skin barrier damage in hairless mice skin that were induced by UVB irradiation and Sq-OOH application.

본 연구의 목적은 외국인 학부생을 대상으로 한 전략 중심의 토론 수업의 효과를 밝히고, 그 결과를 바탕으로 한국어 토론 교육의 새로운 방향을 제안하는 데에 있다. 본 연구에서는 K대학의 선택교양 과목에서 23명의 외국인 학부생을 대상으로 한 학기 동안 전략 중심의 토론 수업을 설계, 진행하였다. 전략중심의 토론 수업은 크게 학습자의 전략 사용을 관찰하는 단계, 토론 전략을 명시적으로 교육하는 단계, 토론 사용을 평가하는 단계 등으로 구성되었다. 한편 토론 전략을 명시적으로 교육하는 단계에서는 주장 전략, 질문 전략, 반박전략 등을 익히고 연습하기를 위한 활동이 제공되었다. 학기 초에 실시한 사전평가와 학기말에 실시한 사후 평가의 결과를 분석한 결과, 토론 수업은 교육적 효과가 있었던 것으로 나타났다. 한편 평가표의 6개의 범주별 교육 효과를 분석한 결과, ‘논리’, ‘화제’, ‘주제’, ‘격식’ 범주에서 교육 효과가 컸다. 4장에서는 그러한 분석 결과를 바탕으로, 향후 전략 중심의 한국어 토론 수업의 방향을 제안하였다. The purpose of this study is to clarify the effects of strategy-oriented debate classes for foreign undergraduates and to suggest a new direction for Korean debate education based on the results. In this study, we designed and conducted strategy-oriented debate classes during one semester for 23 foreign undergraduates studying selected liberal arts subjects at K university. The strategy-oriented debate classes comprised the stages of observing the learner's use of strategies, explicitly teaching debate strategies, and evaluating debate use. At the same time, in the stage of explicitly teaching the debate strategy, we provided activities for learning and practicing the argument strategy, the question strategy, and the refutation strategy. The results of a pre-evaluation at the beginning of the semester and those of a post-evaluation at the end of the semester showed that the debate classes had a positive educational effect. Moreover, the educational effects of six categories of evaluation table were found to be effective in the ‘logic’, ‘topic’, ‘subject’, ‘formal’ categories. Based on these analysis results, the final section of this study proposes a direction for strategy-oriented Korean debate classes in the future.

동남아 로컬 간 한류의 매개와 재생산: 태국-라오스 문화지형을 중심으로

김수은 ( Su Eun Kim ) 한국외국어대학교 동남아연구소 2015 東南亞硏究 Vol.25 No.2

It is remarkable that some foreign countries have reproduced the Korean pop culture these days. In this regard, central to this article is that the indigenized Korean wave is even being distributed by local to local in Southeast Asia. For example, Thailand mediates not only Korean wave but so-called ‘Thai version’ Korean wave for Laos. A closer look at Thai-Lao cultural formation gives characteristic aspects of Laos’ Korean wave: First, in consuming Korean pop culture, Laos has relied on Thai’s TV broadcast. Secondly, Laotians seem to prefer the ‘Thai version Korean wave’ than the original. In addition, there is Korean wave mainly in terms of Korean products consumption. Findings support the idea that the Korean wave is rather than a fixed substance, more of a cultural flow which could be dynamically transformed, hybridize, and indigenized.

한국어 학습자의 학습 환경 변화에 대한 인식 연구

김수은(Su Eun Kim) 한국중원언어학회 2016 언어학연구 Vol.0 No.38

This study was initiated by two research questions: 1) what are Korean-learning as an L2 students aware of about their L2 learning environments, and 2) how do they experience the L2 learning classrooms as their learning environments change. Therefore, this study was intended to investigate the case of German learners who started learning L2 abroad and continued learning L2 during the period of their student exchange program in Korea. Along with data analysis based on in-depth interviews, this study investigated inter-personal, physical, and psychological factors at play when participants experience the change from ‘an KFL environment where Korean was a foreign language’ to ‘an KSL environment where Korean was native language’. In addition, those factors can reveal student reactions when they draw contrasts between their former and current learning environments, and evaluate the two environments. Participants attempted to adjust to the new environment in a way that maintained their own learning style, while also recognizing the difference between the environments. Furthermore, their new learning environment had effects on their motivation to learn, in terms of expansion, change, reduction, or elimination.

This study aims to understand the operation of Korean language education majors in the Gwangju and Jeonnam provinces before developing the curriculum as part of regional research. In the Gwangju and Jeonnam region, a total of 7 universities offers undergraduate courses in Korean language education. However, this region has a characteristic of first-year Korean students being less than three, and the rest being international students. Besides, there are courses for acquiring Korean language teacher certification and improving Korean communication skills. This study interviewed the four current deans of the department of Korean Language Education among the seven universities to understand curriculum management and listen to their views. First, both Korean and international students significantly influenced academic achievement by setting goals and motivation. Moreover, they mentioned that curriculum management requires a new principle that considers learners in the entire process of selecting and arranging subjects, setting educational goals, developing educational contents and materials, and teaching methods for obtaining a Korean language teaching certificate. Courses related to Korean communication should also be designed based on the students’ goals and the department’s values. Also, they suggested that the use of non-subject activities, development of various subject types, and attempts of teaching methods were necessary. (Gwangju University)

The objective of this study was to evaluate the anti-wrinkle efficacy of Oenothera laciniata methanol extract (OLME) in vitro using human dermal fibroblasts. Specifically, we tested the type-I procollagen synthetic ability of OLME at concentrations of 6.25, 12.5, 25, and 50 μg/mL and noted significantly significant (p<0.05) increases versus the control of 38.7, 74.3, 111.4, and 113.0%, respectively. Using RT-PCR, the expression of MMP-1 mRNA in human dermal fibroblasts treated with 6.25, 12.5, 25, and 50 μg/mL OLME was shown to have decreased when compared to the control by 67.7, 71.7, 75.6, and 84.3%, respectively (p<0.05). When measuring MMP-2 activity in human dermal fibroblasts treated with 6.25, 12.5, 25, and 50 μg/mL OLME using zymography, it was shown to have decreased versus the control by 27.6, 37.1, 76.3, and 93.9%, respectively (p<0.05). OLME was less cytotoxic to human dermal fibroblasts than ascorbic acid. From these results, we found that OLME is highly efficacious in its ability to promote collagen synthesis and inhibit its degradation in human dermal fibroblasts, similar or even superior to those of ascorbic acid, a well-known anti-skin aging agent. Therefore, OLME could be used as a functional cosmetic material for the prevention or alleviation of skin wrinkles induced by ultraviolet rays.

운반이나 시공 상의 문제로 PHC pile과 강관 Pile을 강재 연결구로 연결하여 사용하는 경우가 많이 있다. 본 연구에서는 PHC pile과 강관 pile의 연결부를 유한요소해석을 통하여 안정성을 평가하였다. 전산해석 프로그램인 ABAQUS를 이용하여 연결부의 휨. 압축, 인장강도를 검증하였으며, 이연구를 통해 PHC 파일 및 강관 파일의 연결부에 대한 안정성을 확보하였다. Bored pre-cast pile using PHC pile is an appropriate method in urban area because noise and vibration are low. These days, they attach PHC pile and steel pile to make a foundation because of transport and construction problems its. PHC and steel pile joints are welded or bolted. But the bolt connection method is not well used because stability has not been verified. In this paper, bolt joint of the PHC and steel pile was analyzed numerically using a commercial finite element software ABAQUS. The bending, compressive and tensile strength and the structural stability were evaluated.

아스팔트 포장은 균열 및 소성변형 등의 파손으로 설계 수명을 다하지 못하고 조기 파손되는 경우가 많다. 본 연구에서는 복합 섬유 보강재를 사용 여부에 따른 단순보를 설계하여 유한요소해석을 진행하였다. 전산해석 프로그램인 ABAQUS를 이용하여 설계된 보의 상대적인 강도, 응력, 처짐을 확인하였다. 이 연구를 통해 복합 섬유 보강재가 구조적으로 효과적임을 확인하였다. Asphalt pavement is often broken early due to failure such as cracking and plastic deformation. In this study, finite element analysis was carried out by designing simple beams according to the use of composite fiber reinforcement. The relative strength, stress, and deflection of the designed beams were verified using the commercial finite element analysis program ABAQUS. Through this study, we confirmed that composite fiber reinforcement is structurally effective.

살바도르 달리의 회화 작품과 영화 <안달루시아의 개>에 나타난 공통 이미지의 언캐니성

김수은(Kim Su Eun) 동국대학교 영상문화콘텐츠연구원 2017 영상문화콘텐츠연구 Vol.13 No.-

영화 <안달루시아의 개>는 초현실주의 화가 살바도르 달리와 영화 감독 루이스 브뉴엘이 공동으로 제작한 작품이다. 이 작품은 오토마티즘을 이용하여 장면-씬(scene)들의 인과성이 배제된 초현실주의 경향을 보여주는 대표적인 영화이다. 영화 <안달루시아의 개>(1929)는 영화제작 이전의 살바도르 달리의 회화작품에서 발견되는 기표-이미지들이 재현된다는 점에서 영화와 회화의 상호 관련성에 대한 검토를 필요로 한다. <안달루시아의 개>는 형식과 내용적 측면에서 기존 영화와 차별화된 양상을 보여준다. 첫번째 형식적 측면에서는 파편화된 신체 이미지들이 인과성에 의한 선형적 서사 구조를 탈피하고 있다. 두 번째 내용적 측면에서는 모핑 기법을 통한 형질 변환(Metamorphosim) 이미지를 제시해 무의식적 욕망을 표출하고 있다. 형식과 내용에서 기존의 영화와 차별화된 양상을 보여주며 이는 달리의 회화의 영향에 기인한다고 여겨진다. 달리의 회화와 <안달루시아의 개>에서는 ‘낯설게 하기’인 언캐니성이 공통적인 미학적 요소로 배치되어있다. 이는 영화적 미장아빔과 언캐니성의 상호 관련성이라는 점에서 미학적 해명이 요구된다. <안달루시아의 개>는 영화 제작 이전의 달리 회화 작품들의 이미지가 가시적인 미장아빔으로 배치되어 <안달루시아의 개>의 언캐니성을 형성한다. 회화와 영화의 상호 텍스트성은 <안달루시아의 개>에서 달리의 회화 이미지가 영화적 미장아빔으로 배치되고 언캐니성을 재현함으로써 입증된다. <An Andalusian dog> is a collaboration with surrealist painter Salvador Dali. This work is a representative movie that shows the surrealist tendency in which the causality of scenes-scenes is excluded by using automatism. <An Andalusian dog> shows different aspect from existing film in terms of form and contents. In the first formal aspect, the images of fragmented body images escape the linear narrative structure by causality. In the second contextual aspect, we express the unconscious desire by presenting the transformation image(Metamorphosim) through the morphing technique. It shows different aspect from the existing film in form and contents, and it is considered to be caused by the influence of Dali"s painting. In Dali"s paintings and films, An Andalusian dog, uncanny, which is "unfamiliar", is arranged as a common aesthetic element. This requires aesthetic clarification in terms of the interrelation of cinematic mise en abyme with uncanny. <An Andalusian dog> forms the uncanny character of <An Andalusian dog> by arranging visual images of Dali"s paintings prior to film production as visibles. The intertextuality between painting and movie is proved by the image of Dali in <An Andalusian dog>, which is arranged as a cinematic mise en abyme and reproduces uncanny.
