        미국 포장디자인의 역사적 발달과정에 대한 고찰 : 1900~1990년대까지

        윤현정 커뮤니케이션디자인협회 시각디자인학회 1998 커뮤니케이션 디자인학연구 Vol.2 No.-

        Package has developed from the wisdom of life, beginning with mankind. The origin of package is expected when human beings became independent in groups and results from the necessity for storage, distribution, and delivery. In the past, natural material was used for packaging, but as science has been developing day by day, manufactured material of superior quality has appeared. Since the industrial revolution in the 18th century, the trend changed into mass manufacture and mass sale, and finally the package for mass distribution was realized. In order to examine the progress of package design according to the stream of ages, this study investigated the changes of American package design from 1900s to 1990s. The package design was improved by mutually organic interaction from the viewpoint of invention of package material, advance of manufactured food techniques, and progress of distribution konwhow. I hope it will be helpful for the package design world in the coming age by examining the progressive trend and design cases according to such a historical stream.

        Selling Political Brands and Building Candidate Relational Equity in American Campaign Tournaments

        윤현정 서울대학교 미국학연구소 2017 미국학 Vol.40 No.2

        The current study explored whether political candidates' brand building through sequential campaign messages establishes degrees of candidates' relational equity with voters in American politics. Adopting Keller's sequential Customer-Based Brand Equity model, the current study developed the Voter-Based Candidate Brand Equity model to observe how American voters and candidates exchange political brand equity through candidates' sequential branding. Over the course of the 2012 televised American presidential debates, three sequential panel experiments found that the candidates' cumulative brand building created their political identities in voters' minds, sent their political meanings to voters, and brought out voters' responses to their campaign promises. However, candidate branding through the sequentially televised debates alone did not achieve a level of intense relational association with voters to secure their loyalty support. This voter-oriented post-hoc approach explains the progressive campaign effects that have been left unanswered by traditional ad-hoc candidate-oriented perspectives and theories.

        소리의 그림 표현 능력에 대한 연구

        윤현정 한국일러스트레이션학회 2008 일러스트레이션 포럼 Vol.16 No.-

        미술교육은 미술을 기능적으로 지도하는 것 뿐 만 아니라 미술을 통해 어린이들의 시각이 발달하면서 지적인 능력을 통해 종합적인 사고력을 길러 주는 것이다. 본 연구에서는 어린이들이 청각능력을 통한 소리의 인지능력을 그림으로 어떻게 표현 할 수 있는지 알아보고자 한다. 21세기는 정보와 문화의 사회로 다양한 영상과 음악 및 소리들을 통하여 시각적 표현과 연결성으로 예술에 적용이 되고 있다. 특히 미술은 해석 할 수 없는 감각적인 대상의 창조를 통해 개인 간의 주관적 지식에 관한 의사소통이 가능 하도록 한다. 이러한 관점에서 보면, 어린이들은 미술을 통해 정서와 인식간의, 또는 감정과 사고간의 거리를 초월하게 되는 것이다. 본연구자는 소리를 인지 한 후 창조적 자기표현 방법을 통한 미술 표현을 통하여 어린이가 그가 속한 문화에서 통용되는 다양한 상징적 매개물을 “듣고” 해독하는 법을 배울 수 있게 되며, 그가 속한 문화에 존재하는 다양한 상징적 형식을 “표현하는 법”을 배우게 되는 과정을 연구하여 창의적 미술 교수학습의 기저로 삼고자 한다. 구체적인 연구방법은 다음과 같다. 첫째, 본 연구에서 개발하고자하는 프로그램은 교육의 목표 설정, 학습경험의 선정, 학습경험의 조직 학습경험의 평가 과정을 거치는 Tyler의 교육과정 개발모형을 따른 창조적 자기표현 프로그램을 개발한다. 둘째, 개발된 프로그램을 통하여 학생집단을 통한 실험 연구를 한다. 셋째, 실험 연구의 결과를 토대로 아동의 소리를 그림으로 표현 할 수 있는 능력을 검증하고, Gardner와 Eisner의 이론에 비추어 근거 이론을 탐색해 보도록한다. Art education teaches children art technically, and also develops children's general ability to think by enhancing visual ability. In this research we would like to find out how children epresent auditory material into visual material. In the 21st century, a century of information and culture, many artists are connecting visual and auditory senses as a new method of art. Especially art creates a object which cannot be translated, but allows individuals to communicate subjective knowledge. In this point of view children can surpass the emotional distance through art. Through this research we will find out how children "decode" auditory symbols and how children "illustrate" those symbols into visua material and use this as a basis of creative art education. Specific methods of research are,First, develop a creative self expression program based upon Tyler's education process development model. Second, use the developed program to experiment on student groups. Third, seek basis theory using Gardner and Eisner's theory with the results of the experiment Keyword : Art education, expression, auditory symbols

        T2 Values of Femoral Cartilage of the Knee Joint: Comparison between Pre-Contrast and Post-Contrast Images

        윤현정,윤영철,최봉근 대한영상의학회 2014 Korean Journal of Radiology Vol.15 No.1

        Objective: To retrospectively evaluate the relationship between T2 values of pre- and post-contrast magnetic resonance (MR) images of femoral cartilage in patients with varying degrees of osteoarthritis. Materials and Methods: A total of 19 patients underwent delayed gadolinium-enhanced MRI of cartilage. Six regions of interest for T2 value measurement were obtained from pre- and post-contrast T2-weighted, sagittal, multi-slice, multi-echo, source images in each subject. Regions with modified Noyes classification grade 2B and 3 were excluded. Comparison of T2 values between pre- and post-contrast images and T2 values among regions with the grade 0, 1 and 2A groups were statistically analyzed. Results: Of a total of 114 regions, 79 regions showing grade 0 (n = 46), 1 (n = 18), or 2A (n = 15) were analyzed. The overall and individual T2 values of post-contrast images were significantly lower than those of pre-contrast images (overall, 35.3 ± 9.2 [mean ± SD] vs. 29.9 ± 8.2, p < 0.01; range of individual, 28.9-37.6 vs. 27.1-36.4, p < 0.01). Pearson correlation coefficients showed a strong positive correlation between pre- and post-contrast images (rho-Pearson = 0.712-0.905). T2 values of pre- and post-contrast images of the grade 0 group were significantly lower than those of the grade 1/2A group (pre T2, p = 0.003; post T2, p = 0.006). Conclusion: T2 values of the femoral cartilage of the knee joint are significantly lower on post-contrast images than on precontrast images. Furthermore, these T2 values have a strong positive correlation between pre- and post-contrast images.

        헤르페스각막내피염의 임상양상 및 예후인자 분석

        윤현정,지영석,윤경철 대한안과학회 2017 대한안과학회지 Vol.58 No.5

        Purpose: We aimed to analyze the clinical features of herpetic endotheliitis and to investigate the risk factors for recurrence of herpetic endotheliitis and corneal decompensation. Methods: The medical records of 58 patients (58 eyes) who were diagnosed with herpetic endotheliitis were retrospectively reviewed. Patients with a follow-up period of less than 6 months and a previous history of ocular inflammation were excluded from this study. We recorded visual acuity, intraocular pressure, central corneal thickness, and endothelial cell density on both initial and final visit, and recorded clinical findings of the anterior and posterior segments of the eye only on initial visit. Factors affecting the recurrence of herpetic endotheliitis and corneal decompensation were also analyzed. Results: Among the 58 patients, 45 patients had disciform type endotheliitis, 11 patients had diffuse type, and 2 patients had linear type. There were no significant differences between final clinical manifestations according to subtype. 14 patients exhibited recurrence of herpetic endotheliitis. High intraocular pressure and high-grade anterior chamber cells were associated with the recurrence of herpetic endotheliitis. On multivariate analysis, the only risk factor for the recurrence of herpetic endotheliitis was high intraocular pressure. We found that 8 patients exhibited corneal decompensation, and high intraocular pressure, high anterior chamber cell grade, and a history of cataract surgery were associated with corneal decompensation. On multivariate analysis, the risk factors for corneal decompensation were high anterior chamber cell grade and cataract surgery history. Conclusions: For herpetic endotheliitis, the subtype did not affect the final records of clinical manifestation, and the only risk factor for the recurrence of herpetic endotheliitis was high intraocular pressure. Additionally, the risk factors of corneal decompensation were found to be high-grade anterior chamber cells and a history of cataract surgery. Initial examinations of clinical manifestation are important for the successful treatment of herpetic endotheliitis. 목적: 헤르페스각막내피염의 임상양상을 알아보고, 재발 및 각막부전 발생의 위험인자에 대하여 분석하고자 한다. 대상과 방법: 2008년 1월부터 2015년 12월까지 본원에서 헤르페스각막내피염으로 진단받고 6개월 이상 경과관찰이 가능하였던 58명 58안을 대상으로 의무기록을 후향적으로 분석하였다. 초진 시 전신질환, 시력, 안압, 세극등현미경 임상소견과 각막내피세포수, 중심각막두께를 측정하였고, 치료 후 시력, 안압, 중심각막두께를 헤르페스각막내피염의 재발 및 각막부전이 발생한 군과 발생하지 않은 군으로 나누어 분석하였다. 결과: 58안 중 45안(77.6%)에서 원판형, 11안(19.0%)에서 미만형, 2안(3.4%)에서 선형의 임상양상을 보였다. 헤르페스각막내피염의 종류별로 치료 후 결과를 비교분석하였을 때 통계적으로 유의한 차이는 없었다. 14안(24.1%)에서 헤르페스각막내피염이 재발하였으며, 헤르페스각막내피염이 재발하였던 군은 재발하지 않았던 군에 비하여, 초진 시 안압이 높았고, 전방 내 염증이 많았다. 다변량분석에서 헤르페스각막내피염 재발의 위험인자는 안압이었다. 각막부전은 8안(13.8%)에서 발생하였으며, 각막부전이 발생한 군은 각막부전이 발생하지 않았던 군에 비하여, 초진 시 안압이 높았고, 전방 내 염증이 많았으며, 백내장수술을 시행 받은 과거력이 있었던 경우가 많았다. 다변량분석에서 각막부전의 위험인자는 전방 내 염증 및 백내장수술 기왕력이었다. 결론: 헤르페스각막내피염의 아형별로 치료 후 임상 결과는 통계적으로 유의한 차이가 없었고, 재발의 위험인자는 초진 시의 높은 안압, 각막부전의 위험인자는 많은 전방 내 염증 및 백내장수술의 기왕력임을 알 수 있어, 초진 시의 임상양상을 정확하게 평가하는 것이 헤르페스각막내피염의 치료에 도움이 될 것으로 생각된다.

        온라인 액체크로마토그래프-고분해능 질량분석기를 이용한 하천수 중극성유기화합물질의 동시분석

        윤현정,오진아,정건희,유충석,박상현,강태구,강태구 한국환경분석학회 2019 환경분석과 독성보건 Vol.22 No.4

        We categorized 78 hazardous polar organic compounds containing pharmaceuticals and personal care products (PPCPs), pesticides, and industrial chemicals potentially discharged into a river. We developed an automated online liquid chromatography-high resolution mass spectrometric (LC-HRMS) method for the rapid simultaneous determination of 78 polar organic compounds. The method was validated in terms of calibration curve linearity, limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision. The LOD and LOQ were in the range of 0.03-47.6 ng/L and 0.1-151 ng/L respectively. Good accuracy and precision were also obtained. The concentrations of 78 compounds were determined in river water samples, and 60 compounds were detected. Caffeine was the most frequently observed PPCPs in river water.
