본 연구는 국내 전문 코치들을 대상으로 인공지능(AI) 기술 도입이 코칭 산업 의 업무 방식과 전문성, 서비스 전달 구조에 미치는 영향을 분석하고, AI 코칭의 활용 실태와 요구도를 실증적으로 규명하는 데 목적이 있다. 이를 위해 (사)한국 코치협회 인증자격(KAC, KPC, KSC)을 보유한 현직 코치 495명을 대상으로 온 라인 설문조사를 실시하였으며, 수집된 자료는 SPSS 28.0을 활용하여 빈도분석 과 교차분석을 수행하였다. 연구 결과, 응답자의 75.3%가 AI 도구를 코칭 실무에 활용하고 있었으며, 주 요 활용 영역은 코칭 콘텐츠 생성과 전략 수립이었다. 기대 효과로는 접근성과 유연성 향상, 데이터 기반 자기 성장 지원이 높게 나타났고, 도전 과제로는 인간 적 요소의 약화, AI 신뢰성 문제, 개인정보보호 및 보안 이슈가 제기되었다. 또 한 자격 수준과 경력이 높을수록 AI 활용도가 높고, 데이터 윤리와 거버넌스 리 스크를 보다 중요하게 인식하는 경향이 확인되었다. 이는 AI가 코치를 대체하기 보다 하이브리드 코칭 모델에서 전략적 자원으로 활용되어야 함을 시사한다.
Bootleg fashion emerged from the fashion industry after 2010, and has been used across a range of different genres. However, it has yet to be theoretically established; therefore, this study will explain bootleg fashion as a new genre, which will help in the planning and designing of products within domestic fashion brands. The purpose of this study was to examine the characteristics and internal meaning of bootleg fashion as a recently emerged fashion phenomenon that borrows from other brands without permission. The research methodology included a theoretical literature review of fashion sites and related materials and empirical research using case analysis. Results of the analysis of both characteristics and internal meaning of bootleg fashion suggest the following characteristics:ᅠ“unauthorized use of symbolic elements,” “disorganization of boundaries between fashion,” “multiplicity through globalization,” and “newness through deconstruction and recombination.” Internal meanings derived from the analysis were “parody through symbol,” which is seen as “a parody and homage resulting from the unauthorized use of a brand,” while “decomposition through disorganization” is seen as a break-up of the boundaries between different fashions from a mainstreamoriented perspective. A juxtaposition of elements was demonstrated by “playfulness through transformation,” which showed that such fashion cannot coexist with positional transposition. Finally, “spread as a cultural phenomenon” was derived through the diffusion through digital media with DIY culture. As such, bootleg fashion has been reborn as an innovative fashion genre, breaking the taboo of the illegitimate from the past and demonstrating new endeavors.
Human embryonic stem (ES) cells are derived from the inner cell mass of the preimplantation embryo. Human ES cells have the capacity to differentiate into various types of cells in the body. Human ES cells are indefinite source of cells for cell therapy in various degenerative disorders including neuronal disorders. Directed differentiation of human ES cells is a prerequisite for their clinical application. The objective of this study is to develop the culture condition for the derivation of neural precursor cells from human ES cells. Neural precursor cells were derived from human ES cells in a stepwise culture condition. Neural precursor cells in the form of neural rosette structures developed into neurospheres when cultured in suspension. Suspension culture of neurospheres has been maintained over 4 months. Expressions of nestin, soxl, sox2, pax3 and pax6 transcripts were upregulated during differentiation into neural precursor cells by RT-PCR analysis. In contrast, expression of oct4 was dramatically downregulated in neural precursor cells. Immunocytochemical analyses of neural precursor cells demonstrated expression of nestin and SOX1. When induced to differentiate on an adhesive substrate, neuro-spheres were able to differentiate into three lineages of neural systems, including neurons, astrocytes and oligo-dendrocytes. Transcripts of sox1 and pax6 were downregulated during differentiation of neural precursor cells into neurons. In contrast, expression of map2ab was elevated in the differentiated cells, relative to those in neural precursor cells. Neurons derived from neural precursor cells expressed NCAM, Tuj1, MAP2ab, NeuN and NF200 in immunocytochemical analyses. Presence of astrocytes was confirmed by expression of GFAP immuno-cytochemically. Oligodendrocytes were also observed by positive immuno-reactivities against oligodendrocyte marker O1. Results of this study demonstrate that a stepwise culture condition is developed for the derivation of neural precursor cells from human ES cells.
