Ti(dibenzoylmethane)2(O-i-Pr)2 합성과 L-락티드 개환중합

유지연,정하영,고영수 한국고분자학회 2018 폴리머 Vol.42 No.2

Poly(L-lactide)(PLA) 중합용 신규 촉매를 개발하기 위하여 Ti(O-i-Pr)4와 dibenzoylmethane(dbm)을 이용, Ti(dbm)2(O-i-Pr)2 촉매를 합성하였고 PLA 중합특성을 확인하였다. Ti(dbm)2(O-i-Pr)2 촉매 PLA 중합 특성은 L-락티드/촉매 몰비 및 중합시간을 변화시키며 관찰하였다. L-락티드/촉매 몰비가 증가함에 따라 전환율과 분자량이 증가하였다. Ti(dbm)2(O-i-Pr)2 촉매는 촉매 내 페닐기가 존재하여 중합 반응 중 락티드 삽입을 방해하기 때문에 촉매 활성이 낮은 것으로 판단된다. Benzyl alcohol을 개시제로 사용하여 중합한 결과 Ti(dbm)2(O-i-Pr)2 촉매 전환율이 대폭 감소하였다. 얻어진 중합물은 DSC, GPC를 이용하여 녹는점과 분자량을 측정하였고 1H NMR로 PLA의 분자구조를 확인하였다.

사이버보안 정규교육화를 위한 주요국 교육체계 비교분석 연구

유지연 국제문화기술진흥원 2021 The Journal of the Convergence on Culture Technolo Vol.7 No.1

최근 지능정보사회로의 진입으로 인해, 사이버보안 패러다임이 변화하기 시작하였다. 특히 지능정보사회의 상호연결성 등 의 증가는 사이버위협으로 인한 피해 범위를 실제 세계까지 확대하였으며, 개개인에 대한 위험이 곧 공공 안전·국가 안보 등의 위기로 연결되고 있다. 특히 디지털 네이티브(Digital Native)세대인 청소년의 경우는 사이버 활동이 많고 보안 및 안전의식이 충 분치 않아 사이버위협에 그대로 노출 될 가능성이 더욱 크다. 이에 사이버위협으로부터 개인 스스로를 지키고 사이버활동을 관 리할 수 있는 사이버보안 역량 강화가 필요하다. 따라서 본 논문에서는 사이버보안 역량을 강화할 수 있는 사이버보안 정규교육 화에 대해 검토하고 대응방안을 제시하고자 한다. 초연결사회 특성에 따른 보안 패러다임 변화와 사이버보안 교육의 필요성에 대해 검토하고 국내외 사이버보안 교육 추진 현황에 대한 분석을 통해 사이버보안 교육 방향 및 기본 체계를 제시하고자 한다. 이에 본 연구는 지능정보사회에서 요구되는 사이버보안역량을 정의하고 사이버보안역량 함양에 관한 주요국 교육체계를 비교․ 분석하여 사이버보안역량 강화를 위한 정규교육과정을 제안하고자 하였다. 이에 디지털시민으로서의 사이버역량 체계 모델인 C3-Matrix를 반영하여 사이버보안역량 체계를 사이버인식(cyber ethics awareness), 사이버행동(cyber ethics behavior), 사이버 보안(cyber security), 사이버안전(cyber safety)로 구성하였다. 그리고 사이버보안역량 체계 기본구성틀에 기반하여 미국, 호주, 일본, 한국에서 수행되는 관련 교육을 비교분석하고 한국 교육과정에 도입되어야 하는 사이버보안역량 교과체계를 제시하였다. With the recent phenomenon of the Intelligence Information Society, the cyber security paradigm has begun to change. In particular, the increase of the interconnectedness of the hyperlinked society has extended the scope of damage that can be caused by cyber threats to the real world. In addition to that, it can also be a risk to any given individual who could accompany a crisis that has to do with public safety or national security. Adolescents who are digital natives are more likely to be exposed to cyber threats, which is mainly due to the fact that they are significantly more involved in cyber activities and they also possess insufficient security comprehension and safety awareness. Therefore, it is necessary to strengthen cyber security capabilities of every young individual, so that they can effectively protect themselves against cyber threats and better manage their cyber activities. It examines the changes of the security paradigm and the necessity for cyber security education, which is in direct accordance to the characteristics of a connected society that further suggests directions and a basic system of cyber security education, through a detailed analysis of the current state of Domestic and Overseas Cyber Security Education. The purpose of this study was to define cybersecurity competencies that are necessary within an intelligent information society, and to propose a regular curriculum for strengthening cybersecurity competencies, through the comparison and meticulous analysis of both domestic and overseas educational systems that are pertinent to cybersecurity competencies. Accordingly, a cybersecurity competency system was constructed, by reflecting C3-Matrix, which is a cyber competency system model of digital citizens. The cybersecurity competency system consists of cyber ethics awareness, cyber ethics behavior, cyber security and cyber safety. In addition to this, based on the basic framework of the cybersecurity competency system, the relevant education that is currently being implemented in the United States, Australia, Japan and Korea were all compared and analyzed. From the insight gained through the analysis, the domestic curriculum was finally presented. The main objective of this new unified understanding, was to create a comprehensive and effective cyber security competency curriculum.

공동 음악창작 특성에 관한 연구: 송라이팅 캠프를 중심으로

유지연 한국엔터테인먼트산업학회 2018 한국엔터테인먼트산업학회논문지 Vol.12 No.4

With increasing competitions in the Korean music market, the life-cycle of music has been ever shortened. Recently, there is a noticeable phenomenon found that multiple creators participate on creating music, taking part of each role in the process. Therefore, this study intends to explore a new type of co-writing system called ‘songwriting camp’. This article seeks to analyze the characteristics drawn from the co-writing process, and then suggests the practical implications to the Korean music market. In doing so, I interviewed composers and music publishers who have experiences to participate on songwriting camp held in Korea. As a result, this research found that the songwriting camp is a space where the collaboration is maximized and creativity is highly emerged through co-writing process. The participants take a strategy to distribute their ability effectively fit to everyday session on purpose of getting ‘cut’. I argued that this co-writing system through a songwriting camp may lead to the dilemma that differentiation and identity of music are blurred due to the overflow of a similar level and quality of music. To make better use of songwriting camp, I suggest that it would be better to explore diverse uses of it within the Korean local music market to bring more creative and various collaborations between creators.

Shamed Women and Praised Women: Establishing Male Authorial Voices in the Female Complaints of 1590s England

유지연 한국고전중세르네상스영문학회 2023 중세근세영문학 Vol.33 No.3

Through intertextual literary analysis of sonnets and narrative complaints, this article examines how male poets establish their poetic authority by ventriloquizing female voices as portrayed in the convention of female complaints in 1590s England. Even though female figures in complaints are given a space to contest their situations, their voices are appropriated by sonnet speakers who come in to moralize their stories as exemplified in Daniel’s The Complaint of Rosamond and Lodge’s The Complaint of Elstred. In both poems, Rosamond and Elstred make themselves symbols of feminine shame, arising from the pursuit of vainglory. While Drayton’s virtuous Matilda exerts a much stronger authorial power in verse, fame is not bestowed upon her; instead, it is replaced by the poet’s pursuit of literary and national fame. With this analysis of female complaints, this article illustrates the gender ideology of fame and authorship in early modern English poetry.

상악 전치부 잔존 유치와 매복 견치 발치 후 즉시 임플란트 식립: 증례 보고

유지연,김여갑,이백수,권용대,최병준,김영란,백진,Yoo, Ji-Yeon,Kim, Yeo-Gab,Lee, Baek-Soo,Kwon, Yong-Dae,Choi, Byung-Joon,Kim, Young-Ran,Baek, Jin 대한악안면성형재건외과학회 2009 Maxillofacial Plastic Reconstructive Surgery Vol.31 No.4

저자들은 본 증례의 경우 치근이 흡수된 전치와 매복 견치의 발치 후 심한 치조골의 흡수와 연조직의 변화가 예상되는 것을 고려하여 발치 후 즉시 임플란트 수술을 결정하였다. 초기 안정성을 확보하기 위해 가능한 적은 골삭제, 보다 큰 직경과 치근형태의 임플란트를 선택하여 발치 후 즉시 임플란트를 식립하였고, 장골에서 채취한 망상골로 골결손부를 채우고 부가적으로 상순 지지를 위해 흡수성 차폐막과 순측 골면에 onlay형태의 골이식술을 시행하여 자연스럽고 심미적인 결과를 얻을 수 있었다. Alveolar bone resorption after extraction impairs the necessary bone volume and complicates the case for implant surgery and aesthetic implant prosthesis. Immediate implant surgery after extraction decreases the number of surgical procedures and the duration of treatment, while allowing minimum alveolar bone resorption and preserving the residual bone volume. Although immediate implant holds many advantages such as preservation of hard and soft tissue around the extraction socket, greater implant survival rate and higher patient satisfaction, various complications and high failure rate are discouraging factors for the clinicians. In this case report, severe alveolar bone resorption with soft tissue changes were predicted after the extraction of prolonged retained deciduous incisors and impacted maxillary canines and thus decided on immediate implant procedure. Immediate implant surgery after extraction was carried out with minimal bone reduction and tapered wide-neck implant to establish initial stability. Simultaneous bone graft was done by filling the defect area with iliac cancellous bone with additional onlay-type bone graft and absorbable membrane on the labial bone for upper lip support. A stable and esthetic result was obtained with shortened treatment period.
