This paper tried an approach of oral literature as the research subject of Soeburi song in Ulsan. First, UlsanSoeburi song is meaningful as materials collected in Ulsan such as Hansil, Dodoekgol, Dudong and Byeongueong. In addition, it is related to regional identity as song native to Ulsan, which has prototype and archetype. And it shows that Ulsan is the city as well as hometown of Soeburi(meaning ' iron manufacture'). The characteristics of lyrics are different between Hansil Soeburi song and Dodeokgol Soeburi song. Jeiman Choi is considered as a good oral literature poet, because he is a performer who is faithful in official structural principal and in original lyrics(archetype) of Soeburi song. Therefore, SoeburiBulmei song of Jeiman Choi signifies aesthetic meaning, having lyrics which make to feel labor's purity and sacred and melody which overcomes labor's difficulty through united action. On the other hand, SoeburiBulmei song of Dalo Kim in Doseokgol shows that he is a extemporaneous performer even though he performs based on official structural principal. In this paper, transmission and changes of UlsanSoeburi song are divided into basic type, frequent shift type and overall type. 'Basic type' originates from Jeiman Choi's Soeburi song in Hansil. 'Frequent shift type' was created by combining SoeburiBulmei song of Dalo Kim in Doseokgol and SoeburiGeumjul song in Ulsan. 'Overall type' is current Soeburi song, which was created by adding Bulmei song for lulling a baby in Byeongueong near Dalcheon region and Seoknyanggan(smithy) Bulmei song. UlsanSoeburi song is being passed down continuously, strengthening the identity as a representative folk song in Ulsan through endless process of transmission and changes.

본 고는 ISO/IEC JTC 1/SC 29/WG 7 MPEG(Moving Picture Experts Group) 3DG(3D Graphics coding) 그룹에서 진행되고 있는 포인트 클라우드 데이터 압축 표준 기술 중 하나인 G-PCC(Geometry-based Point Cloud Compression) 표준에 대하여 설명하고자 한다. G-PCC는 포인트 클라우드의 기하 정보와 속성 정보를 3차원 공간에서 서로 다른 기술을 이용하여 압축하는 표준으로, 무손실 압축 방법의 경우 10:1의 압축율을 제공하고 손실 압축의 경우 35:1 정도의 압축율을 보인다. 본 고에서는 G-PCC의 기하 정보와 속성 정보의 압축 방법을 상세히 설명하고 같은 기능을 수행하는 압축 기술 간의 성능을 비교하고자 한다.

본 논문에서는 압축 영역에서 열 영상을 이용한 딥러닝 기반의 객체 검출 방법을 제안한다. 비디오 압축 표준인 High Efficiency Video Coding(HEVC)를 이용하여 부보화된 비트스트림으로부터 Intra Prediction Mode(IPM), Prediction Unit Size(PUS), Transform Unit Size(TUS)를 추출하고 3 채널 영상으로 변환하고 객체 검출 네트워크인 YOLO 에 입력으로 넣어주어 최종적으로 객체의 위치 및 객체의 종류를 예측한다. 실험결과로써 복원된 열 영상과 검출된 결과를 주관적으로 보여줌으로써 압축영역에서 열영상을 이용한 객체 검출이 가능함을 보인다.

본 논문에서는 동적 포인트 클라우드 압축 표준인 V-PCC 을 기반으로 고밀도 동적 메쉬 데이터를 압축하는 방법을 제안한다. 제안하는 방법은 정점마다 색상 값을 갖는 고밀도 동적 메쉬 데이터 압축 구조로 정점마다 갖는 위치 정보와 색상정보는 V-PCC 를 통해 압축을 수행하고 정점들의 연결정보는 TFAN 기술을 통해 압축을 수행한다. 이때 V-PCC 를 통해 복원된 정점의 순서와 TFAN 을 통해 복원된 연결정보의 정점 인덱스 정보는 복원 후 변경되어 둘 사이를 매핑 해주기 위한 방법이 필요하다. 본 논문에서는 부호화기에서 3D morton 코드 기반으로 원본 정점과 V-PCC 를 통해 복원된 정점을 효과적으로 매핑하는 방법을 제안한다. 제안하는 메쉬 압축 방법은 기존 MPEG-4 의정적 메쉬 데이터 압축 표준인 SC3DMC 와의 비교를 통해 V-PCC 기반 동적 메쉬 데이터 압축의 효율성을 보인다.

This study attempts to understand the context of shared learning in the trading zone formed by teachers from different backgrounds and the process in which this shared learning varies in the educational context, focusing on the case of 'Woodwork Science Education Study Group.' To do this, data was collected through in-depth interviews with eight teachers who participated in the 'Woodworking Science Education Research Group' and analyzed their responses based on grounded theory. As a result, the causal conditions of the teachers' research group were 'various contexts of entering the trading zone' and the central phenomenon was 'encounter with learning in the trading zone.' Contextual conditions affecting this phenomenon were 'woodwork as a boundary object and individual transfiguration experience,' and action/interaction strategy was 'various efforts and influences in the field.' The intervention condition was 'practical effort and experience in educational field.' Final result in this model is 'the new practice of learning shared in the trading zone.' In selective coating, it was found that the practice of the teacher's research group appears as four types of' 'Extracurricular creative experience type,' 'career education type,' 'curricula education type,' and 'school management type.' The results of this study suggest that the shared learning and antonymous practice among teachers in the teachers' research group as trading zone do not only meet their learning needs but also lead to various teaching practices in the individual teachers' context of education and improve the diversity and quality of education.

Asura: The City of Madness, which was released in 2017, attracted great attention even prior to its release with the combination of Director Kim Sung-su, and actors, Jung Woo-sung, Hwang Jung-min, Ju Ji-hoon and Kwak Do-won. Faithful to its genre as a crime film of film noir, Asura: The City of Madness created multi-layered issues by the overthrow of the archetypal hero character and variation of the heroic narrative structure drew diverse interpretations among both critics and viewers alike. This study aims at analyzing the heroic narrative structure of Asura: The City of Madness based on Christopher Vogler's "The Hero's Journey" and examining how the universality and typicality of narrative structures as mentioned by Vogler are applied to this film. Although the universal and typical characteristics of all narrative structures cannot be analyzed through Christopher Vogler's The Hero's Journey, five atypical characteristics could be derived from this film that deviate from the universality mentioned by Christopher Vogler by looking at the characteristics of the heroic narrative structure implemented as Han Do-kyung, the leading character and a "hero," proceeds through the 12 stages. This study examines which variations such atypical characteristics brought to the heroic narrative structures in crime films what has changed in audiences' expectations, and how it could work as an alternate narrative.
