Intermedia is a term that refers to the convergence of different media. It has not only enabled the delivery of brand message but also developed interactive communication in a contemporary fashion show context. This study investigates the presentation methods of contemporary fashion shows affected by intermedia. We examined the research and theory related to intermedia and fashion shows by accessing articles since the 2000s concerning 252 shows by 30 designers that tended to demonstrate the use of intermedia. Our analysis highlighted four particular characteristics: “medium scalability” (the unity of art and fashion and the unity of life and fashion); “synesthetic flow” (the audience’s emotional immersion, represented by the actual performance and performances of the models); “participatory accessibility” (performance participation through action and instrumental support); and “immaterial symbolization” (an intuitive symbol that emphasizes both the direct outward appearance and the metaphorical symbolism so that the object is expressed in a figurative sense). From these results, we identified considerable synergy between the characteristics of intermedia and contemporary fashion shows. Therefore, it might be useful to conduct an experimental study on this area of research.

역사적 신제도주의 관점에서의 교원 연수 정책 분석: 2010~2019년을 중심으로

This study examines the changing process and characteristics of state-led teacher training in order to analyze the causes and implications of the state-led teacher training policy, which seeks to develop the professionalism of teachers but unable to suggest fundamental solutions and improvement measures, despite the constant demand for improvement. From the perspective of historical neo-institutionalism, this study attempts to analyze the policy objectives and the teacher professionalism underpinning the institutionalization of state-led teacher training and interactions in the structure, institution, and actor-level. The results show that the teacher training policy in Korea went through a gradual change from the policy introduction period (1945-1990), policy settlement period (1991-1999), and quantitative expansion period (2000-2009) to quality management period (2010-2019). In addition, it is argued that the change took the form of layering as a pattern of path evolution. In this study, the quality management period is divided into two periods: first, the quality management period for policy internalization (2010-2013), with the introduction of the teacher evaluation for professional development and evaluation of teacher training institutions. Second, the quality management period for teachers’ capacity-building (2014-2019), with increased diversity in training contents and methods and community approach to teacher learning. Based on the results of the analysis, it is suggested that there is a possibility for establishing a consumer-centered system with enhanced policy outcomes if teachers’ training needs are reflected in the gradual change of the teacher training policy. To this end, however, it is necessary to establish a systematic support system linking Ministry of Education and schools, and to enhance teachers’ participation in their own professional development and instructional capacity-building. 이 연구는 교원의 전문성을 개발하고자 하는 국가 주도 교원 연수 정책이 끊임없는 개선 요구에도 불구하고 본질적인 해결책과 개선 방안을 제시하지 못하는 원인과 그에 대한 시사점을 찾기 위해 국가 주도 교원 연수의 변천 과정과 특성을 분석하는 것을 목적으로 한다. 즉, 역사적 신제도주의 관점에서 국가 주도적인 교원연수가 어떠한 정책적 목표와 교원의 전문성에 대한 이해를 바탕으로 제도화되었으며, 그 과정에서 작용한 구조, 제도, 행위자 수준의 상호작용을 통합적으로 분석하고자 하였다. 분석 결과, 우리나라의 교원 연수 정책은 정책 도입기(해방이후~1990), 정책 정착기(1991~1999), 양적 확산기(2000~2009), 질 관리기(2010~2019)로 나누어 연수 정책이 점진적으로 변화하였으며, 이러한 형태가 경로 진화의 모습으로 가겹(layering)의 양상을 띠고 있음을 알 수 있었다. 또한, 교원 연수 정책이 정착한 이후를 질 관리기로 삼아 교원능력평가 및 교원연수원평가 제도의 도입을 통한 정책 내실화를 위한 질 관리기(2010~2013)와 연수 내용 및 방법의 다양성과 교사학습에 대한 공동체적 접근이 확대된 교원 역량 강화를 위한 질 관리기(2014~2019)로 구분하였다. 분석 결과를 바탕으로 볼 때, 향후 교원 연수 정책이 교사들의 요구와 필요를 반영하여 발전한다면, 정책적 노력의 효과와 함께 수요자 중심의 제도가 마련될 수 있는 가능성을 보여준다. 다만 이를 위해서는 교육부에서 단위학교까지 연계되는 체계적 지원 체제를 구축하고, 교사의 전문성 개발과 함께 교사의 자기주도적 수업 역량 제고를 위한 교사들의 참여를 제고해야 할 것이다.

Chondroprotective Effects of Ulva prolifera on Osteoarthritis through MAPKs Signaling Inhibition
이슬아,한슬희,장지윤,박보람,김춘성 한국식품영양과학회 2023 Preventive Nutrition and Food Science Vol.28 No.1
Osteoarthritis (OA) is a typical degenerative disease that mainly appears in the elderly aged 65 and over. OA is characterized by inflammation and decomposition of the cartilage matrix due to irreversible wear and tear. Ulva prolifera, a green macroalgae species, contains polysaccharides, amino acids, polyunsaturated fatty acids, and polyphenols, which are major active components responsible for anti-inflammatory and antioxidant effects. This study evaluated the chondroprotective effect of 30% prethanol extract of U. prolifera (30% PeUP). Rat primary chondrocytes were pre-treated with 30% PeUP for 1 h before interleukin-1β (10 ng/mL) stimulation. The production of nitrite, prostaglandin E2 (PGE2), collagen type II (Col II), and aggrecan (ACAN) were detected by Griess reagent and enzyme-linked immunosorbent assay. The protein expression levels of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, matrix metalloproteinase (MMP)-1, MMP-3, MMP-13, a disintegrin and metalloproteinase with thrombospondin (ADAMTS)-4, ADAMTS-5, and mitogen-activated protein kinases (MAPKs) (extracellular signal-regulated kinase 1/2, c-Jun N-terminal kinase, and p38) were assessed by western blot. Thirty percent of PeUP significantly inhibited the expression of nitrite, iNOS, PGE2, COX- 2, MMP-1, MMP-3, MMP-13, ADMATS-4, and ADMATS-5 in interleukin (IL)-1β-stimulated chondrocytes. Moreover, 30% PeUP decreased the IL-1β-induced degradation of Col II and ACAN. Additionally, 30% of PeUP suppressed IL-1β-induced phosphorylation of MAPKs. Therefore, 30% PeUP is a potential therapeutic agent to mitigate OA progression.
