Energetic outflow from active galactic nuclei (AGNs) may play a critical role in galaxy evolution. We present a velocity diagnostics for detecting gas outflow in the narrow-line region of Type-2 AGNs using line-of-sight velocity offset of the [O III]${\lambda}5007$ and $H{\alpha}$ emission lines with respect to the systemic velocity of stars in host galaxies. We apply the diagnostics to nearby galaxies at 0.02 < z < 0.05: 3775 AGN-host and 907 star-forming galaxies as a comparison sample, which are selected from the Sloan Digital Sky Survey DR7. After obtaining a best-fit stellar population model for the continuum and a systemic velocity based on stellar lines, we subtract stellar component to measure velocity offsets of each emission line. We find a sample of 169 AGN-host galaxies with outflow signatures, displaying a larger velocity shift of [O III] than that of $H{\alpha}$, as expected in a decelerating outflow model. We find that the offset velocity of [O III] increases with Eddington ratio, suggesting that gas outflow depends on the energetics of AGN.

연구목적: 이 연구는 성공적인 통합교육을 위한 교육적 접근 방법인 보편적 학습설계(Universal Design for Learning: UDL)에 대해 중학교 미술 교사가 그 중요도와 실행도를 어떻게 인식하고 있는지를 분석하고, 이에 근거하여 미술 교과에서 UDL을 구현하기 위한 지원 및 후속 연구의 방향성을 제시하는 것을 목적으로 하였다. 연구방법: 부산광역시 특수학급 설치 중학교에 재직 중인 미술 교사 115명에게 설문지를 배부하였고, 최종적으로 장애학생 지도 경험이 있는 미술 교사 75명이 응답한 설문지 75부를 분석하였다. 연구결과: 연구결과는 다음과 같다. 첫째, 중학교 미술 교사의 배경변인에 따른 UDL 중요도 인식은 통계적으로 유의한 차이가 없었다. 둘째, 중학교 미술 교사의 배경변인에 따른 UDL 실행도 인식 또한 통계적으로 유의한 차이를 보이지는 않았다. 셋째, UDL 실행도는 UDL 중요도보다 상대적으로 낮은 것으로 나타났다. 또한 UDL의 중요도와 실행도 인식은 정적인 상관관계를 보였다. 이는 미술 수업에서의 UDL 적용 필요성을 높게 인식하는 교사일수록 UDL을 실천하는 수준이 높을 개연성을 드러내는 것이다. 결론: 이상의 연구 결과를 토대로 현직교사 대상 특수교육 및 UDL 관련 양질의 연수 기회 확대, 예비교사 양성과정에서의 UDL 관련 교육, UDL이 적용된 미술과 교육과정과 교과 자료 개발 및 보급, 미술 교사와 특수교사의 협력체제 구축 등 향후 통합교육 환경 미술 수업에서 UDL을 구현하기 위한 지원 및 후속 연구의 방향성을 제시하였다. Purpose: This study analyzes how middle school art teachers recognize the importance and performance of universal design for learning (UDL), which is an educational approach towards successful inclusive education. The study aimed to present support for implementing UDL in art instruction and direct the course of prospective follow-up studies. Method: A questionnaire was distributed to 115 art teachers working in middle schools with special classes in Busan. Finally, 75 questionnaires were answered by 75 art teachers with experience in teaching students with disabilities. Results: The research results are as follows. First, there was no statistically significant difference in recognition of the importance of UDL according to middle school art teachers’ background-related variables. Second, there was no statistically significant difference in the recognition of UDL’s performance according to middle school art teachers’ background-related variables. Third, the performance of UDL was relatively lower than the importance of UDL. In addition, the recognition of importance and performance of UDL positively correlated. This shows that the more the teacher recognizes the need to apply UDL in the art class, the higher would be the level of practicing UDL. Conclusion: Based on the results of the present research, it is concluded that to realize UDL in future integrated education environmental art classes, expand learning design training for teachers in general, provide educational opportunities for UDL in teacher training courses and applied arts curricula, and foster cooperation between art teachers and special education teachers. It was suggested that the direction of support and follow-up studies.

미술관의 기능적 및 인지적 이미지가 방문자 평가에 미치는 영향

배현진(Bae Hyun Jin) 조선대학교 조형미술연구소 2012 조형미술논문집 Vol.12 No.2

This study is intended to examine the effect of characteristics of museum visitors and visit type on perceived relative status, aesthetic responses, and perceived visit benefits, which in turn affect visitor satisfaction and personal and social participatory behaviors. Research was held for four weeks. A total of 308 questionnaires were collected out of 315 distributed. However, additional 15 were excluded due to inadequate responses. The findings of the study are as follows: While art museum visitor characteristics yielded significant effects on the perceived relative status and perceived visit benefit, it did not have significant effects on aesthetic responses. Additionally, while visit types showed considerable impact on perceived relative status, it did not yield significant effect on aesthetic responses or the perceived visit benefit. Perceived relative status of a museum had positive effects on aesthetic responses, but not on the perceived visit benefit. Furthermore, while perceived relative status did not have significant effect on visitor satisfaction, it did have evident effects on the aesthetic response and the perceived visit benefit. Lastly, greater visitor satisfaction was confirmed to contribute to greater participatory behavior in various prospective programs and events offered by art museums. Hence, it would be imperative for art museums to gear their attention to encourage internal participatory behaviors such as visitor education, donation and charity events, which would consequently transcend to viewing art museums more as a public space shared by the general public.

무의미한 행위 실천의 의미 : 프란시스 알리스(Francis Alys)와 송동(宋冬)의 작품을 중심으로

배현진 ( Bae Hyun Jin ) 한국동양예술학회 2019 동양예술 Vol.44 No.-

一位生活在墨西哥城的比利時藝術家弗朗西斯·埃利斯(Francis Alys, 1959- )和生活在北京的宋冬(Song Dong, 1966- ), 通過无限重復‘步行’和‘寫作’的日常活動來完成創造无意義行爲的工作。在這篇文章中, 試圖閱讀他們的非生産性和低效率的詩意和社會政治的意義。 第二章, 弗朗西斯·阿爾斯將步行描述爲一種詩意的行爲, 例如, 推着一個巨大的氷塊穿過墨西哥城的大街, 最初氷塊的重量讓他覺得很吃力, 不過隨着時間的推移巨大的氷塊變成人一塊若隱若現的水漬. 他的藝術通過充滿詩意, 進行發問政治、社會的主題, 幷引起了人的努力和勞動的, 與可以擴大政治思想可能性的行爲有關。在第三章, 探討了在20世紀90年代中國當代藝術中以文字寫作來作爲實現行爲藝術家, 而進行說明在宋冬以水作爲紀錄的日記和時間的作品中寫作行爲的無爲態度。 第四章, 將硏究水和油漆的重要性, 這是兩位藝術家在作品中用來練習无意義行爲的典型材料, 以及容易丢失的人類勞動的意義。此外, 通過他們的行走和寫作, 認識到重復的思索和修身過程, 我再次意識到世界上復雜的政治和社會問題, 爲了更接近其含義, 筆者想談論改變人們凝視的行動過程。

아이웨이웨이(艾未未)의 작품 속 오브제를 통한 기억 재현

배현진 ( Bae Hyun Jin ) 한국동양예술학회 2021 동양예술 Vol.50 No.-

Ai weiwei(1957-) is an installation work through objets, containing a common memory of the relationship between individuals and groups, the relationship between humans and society, the subversion and dissolution of traditions, and the inner trauma of the community. From the 1980s, he began to produce works using everyday objects such as clothes, hangers, shoes, and furniture, and since the 1990s, he has carried out handicraft and labor-intensive large-scale installations through repetition, arrangement, overlapping, and accumulation. Ai weiwei uses the formative principle that leads to repetition and overlap of everyday objects, dissolution and distortion, and through this, reveals private and public memories, and reveals the formative characteristics in two opposing perspectives in which a single entity is infinitely created and dismantled. As such, metaphors through objets bring back memories from forgetting about existence and absence, and these works make people confront uncomfortable memories of the past and look back on personal values hidden in the group. The purpose of this thesis is to examine the social characteristics of memories and representations of history and disasters through works using Ai Weiwei's objects, and to identify and analyze the characteristics of primary historical and secondary collective memories. Furthermore, these works are meaningful in that they go beyond the auxiliary function of memory on the premise of oblivion, and serve as a complementary function to ‘Remembering’ the reality that China is trying to conceal and suppress politically, socially and culturally.

The private collection activities of the late Ming dynasty which was developed in the center of Jiangnan spreaded from Suzhou to around Songjiang and Jiaxing. These area showed the highest level of economic growth and the paintings and calligraphic which was the cultural activities based on economic power become a trend. In the case of this thesis, carefully conducted research in Tung Chi-Chang(董其昌) whose the representative of artist and collector in Songjiang from Jiangnan and activities through his social connection. Tung Chi-Chang was involved in government service for long time and interacted with a large number of successful collector especially Han Shi-neng(韓世能), Xiang Yuan-bian(項元판), Wu Ting(吳廷). Tung Chi-chang participated in the collection of calligraphy and paintings, purchase, exchange, copy-training through these people. These innumerable activities made the remarkable contribution to the paintings and calligraphic creation but also to his view of paintings.

동시대 미술관의 퍼포먼스 아트 컬렉션의 지속 가능성 - 테이트 모던(Tate Modern)을 중심으로

배현진(Bae, Hyun-Jin) 한국박물관학회 2021 博物館學報 Vol.- No.40

1960년대 후반 퍼포먼스 아트가 현대 미술 발전에 있어 중요한 역할을 담당하면서 예술가의 행위 자체가 미술로 확장되었을 뿐 아니라 신체를 매개로 한 예술 실천 속에서 관람객의 참여를 적극적으로 유도하였다. 최근 동시대 미술관은 행위와 과정을 강조한 퍼포먼스 아트 컬렉션의 특이성에 적응하며 새로운 방법론을 제시하고 있다. 이에 본 논문의 목적은 2000년대 이후 세계 미술계에서 퍼포먼스 아트의 위상이 높아짐에 따라 영국 테이트 모던(Tate Modern)의 사례를 중심으로 동시대 미술관의 퍼포먼스 아트 컬렉션 확장과 지속 가능성에 대한 의미를 살펴보고자 한다. 특히 테이트 모던이 소장한 ‘위임된 퍼포먼스(delegated performance)’는 일반적인 미술관의 작품 수집과 전시 방식을 벗어난 것으로 개념과 행위로써 작품의 비물질적 요소를 소유하는 과정을 보여주었다. 다시 말해, 예술가의 지시에 따라 작업을 수행할 행위자를 고용하고 이들이 예술가의 퍼포먼스를 대신 수행하도록 위임받는 새로운 형식적 전환을 통해 퍼포먼스 아트의 유연한 지형 변화를 예고하였다. 결론적으로 동시대 미술관의 퍼포먼스 아트 컬렉션은 위임된 형식에 의한 ‘재공연(re-performance)’ 권리를 소장하는 것으로 퍼포먼스 아트의 지속가능성을 확립하였고 동시대 미술관의 새로운 위상 정립과 나아갈 방향을 제시하였다는 의미 있는 결과를 도출하였다. As performance art played an important role in the development of modern art in the late 1960s, the artist’s behavior not only expanded into art, but also actively guided the audience to participate in the art practice using the body as a medium. Recently, the contemporary art museum has proposed a new methodology by adapting to the specificity of performance art collections that emphasize action and process. Therefore, the purpose of this thesis is to examine the meaning of the performance art collection expansion and sustainability of contemporary art museums, focusing on the case of Tate Modern in the UK, as the status of performance art in the global art has been rising since the 2000s. In particular, the “delegated performance” owned by Tate Modern showed the process of possessing the immaterial elements of a work as a concept and action, which went beyond the general art collection and display method of art museums. In other words, it heralded a change in the flexible field of performance art through a new form of transformation in which actors are hired to perform the work according to the instructions of artist and they are delegated to perform the artis’s performance on their behalf. In conclusion, the performance art collection of a contemporary art museum has the right to “re-performance” in a delegated form, which means that it has established the sustainability of performance art, established the new status for contemporary art museums and suggested the future direction.
