Background: Many clinicians tend to assume that psoriasis rarely involves the face, and therefore have little interest in facial psoriasis. However, the face is the most important area of cosmetic concern and social activity, and facial involvement of psoriasis is more common than we think. A few reports have even suggested that facial psoriasis could be a marker of severe psoriasis. Objective: To investigate the epidemiological and clinical characteristics of facial psoriasis. Methods: A total of 235 patients with facial psoriasis were enrolled in this retrospective study at the psoriasis clinic, Department of Dermatology, Seoul National University. Epidemiological and clinical data from patient records was collected and analyzed. Results: The most frequent age of onset for facial psoriasis was in the 3rd decade of life. The peak age of onset of facial psoriasis in male patients was in the 3rd and 4th decade of life, whilst for female patients it was in the 3rd decade. Most patients had presented with facial psoriasis before they were 40. The sites of the face most often affected were the upper (73.9%) and lower (46.2%) aspects of the forehead and periauricular area (45.7%). The eyelid, perioral area and nasolabial fold were relatively unaffected. Patients who had scalp-unrelated facial psoriasis presented with a more severe condition than patients who only had scalp-related facial psoriasis. With reference to the extent of psoriasis, 43.8% of patients were moderate cases, whereas 29.6% were mild and 26.6% were severe. With reference to the activity, 40.3% of patients were mild, while 38.5% were moderate and 21.2% were severe. Family history was observed in 39.9% of patients and nail involvement was observed in 27.7% of patients. Only 38.2% of patients had no pruritus, while 16.3% of patients experienced moderate or severe pruritus. Conclusion: The present retrospective analysis contributes to our understanding of the clinical characteristics of facial psoriasis. (Korean J Dermatol 2006;44(12):1397~1402)

윤현선 ( Hyun-sun Yoon ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.2

Electromagnetic radiation emitted by the sun encompasses a wide spectrum of wavelengths. It has vast and diverse effects on human skin. While the photon energy of visible light (VL) and infrared (IR) radiation is lower than that of ultraviolet (UV) radiation, the VL and IR radiation account for 38.9% and 54.3% respectively, of the incident solar energy, compared to UV radiation representing just 6.8% (0.5% UVB, 6.3% UVA) of solar radiation. However, most studies on human photobiology have focused on UV radiation part of the spectrum. The effects of VL and IR radiation have not been clearly elucidated. Table 1.

공영방송의 스포츠 프로그램 분석

윤현선(Hyun-Sun Yoon) 한국여성커뮤니케이션학회 2011 미디어, 젠더 & 문화 Vol.19 No.-

다매체 다채널 시대를 맞이하여 미디어와 스포츠의 상업화와 스포츠 중계권 논란이 가열되고 있으나, 텔레비전 스포츠 프로그램에 대한 연구는 부족한 실정이다. 어느 누구도 영원한 승자가 될 수 없는 스포츠 중계권 시장의 현실에서, 수신료 수입이라는 재원조달방식의 태생적 한계를 안고 있는 공영방송이 거대 자본으로 무장한 국내외 상업방송과의 무한경쟁에 대응할 수 있는 장기적 방안 중 하나는, 방송사의 역사, 제작기술, 시청자층의 인지도와 신뢰를 바탕으로 한 양질의 스포츠 프로그램의 육성이다. 이 연구는 영국 BBC의 축구 전문 프로그램 〈Match of the Day〉(이하 〈MOTD〉)와 국내 유일한 축구 전문 프로그램인 KBS의 〈비바 K-리그〉의 저널리즘적, 엔터테인먼트적, 드라마적 요소와 직접성, 즉각성, 사실성의 구현을 비교분석했다. 텍스트 비교분석결과, 〈MOTD〉는 저널리즘적 가치와 사실성이 돋보이는 분석적, 경기중심적 구성을 보인 반면, 〈비바 K-리그〉는 엔터테인먼트적 가치와 드라마적 가치가 두드러지는 묘사적, 관계중심적 구성을 보였다. 두 프로그램 모두 직접성, 즉각성의 구현에 있어서는 유사점을 보였다. 이는 프리미어 리그와 K-리그의 규모나 국민적 기반의 현저한 차이, 두 프로그램의 역사와 주시청자층의 구성과 성향의 차이를 반영한 것이며, 〈MOTD〉분석은 K-리그의 저변확대와 발전에 따른 〈비바 K-리그〉의 진화 방향을 제시하고 있다. This study compares the BBC’s 〈Match of the Day (MOTD)〉 and KBS’ 〈Viva K-League〉, the football programmes by the public service broadcasters of the UK and Korea. Despite the rapid increase of TV broadcast rights, growing commercialization of media/sports, and controversy over the universal access, television sports programmes have rarely been studied in the media and cultural studies field. To date there is no comparative analytical work between 〈MOTD〉 and other sports programmes. It therefore aims to fill this lacuna: by employing a comparative textual analysis method, it focuses on practice and expression in these texts. It situates television sport at the intersection of practices of journalism, entertainment and drama and attempts to identify the immediacy, spontaneity and realism. The findings show that 〈MOTD〉 is more influenced by journalism, with a heavy focus on realism whereas the Korean counterpart turns out to be more drama-and entertainment-oriented. In both programmes, the technologically advanced visual devices such as slow motion and replay and graphics are witnessed as the evidence of highlighting immediacy and spontaneity. The differences between the two programmes reflect the differences in history, size, popularity of the Premier League and K-League and indeed the programmes themselves. The study recommends that 〈Viva K-League〉 considers more journalism-oriented approach, with more attention paid to the scheduling strategy.

BBC의 미래 전략 : ‘창조적 미래’ 전략과 중간점검을 중심으로

윤현선(Hyunsun Yoon) 문화방송 2011 방송과 커뮤니케이션 Vol.12 No.1

이 연구는 2006년 발표된 BBC의 ‘창조적 미래’ 전략의 검토와 중간점검을 통해 다매체 · 다채널의 디지털 시대 공영방송의 목표와 철학, 딜레마를 논의한다. 이로써 프로그램의 공익성과 경영의 효율성을 동시에 추구해야 하는 공영방송의 딜레마를 안고 있는 BBC가 제시한 미래 생존 전략의 현주소와 성과, 당면 과제와 시사점을 검토했다. 2010년 발표된 BBC 트러스트의 중간보고서를 중심으로, 현지 언론보도와 인터뷰 내용 등을 참고하고, BBC 웹사이트와 보도자료, 정부 정책문, BBC 웹사이트, 규제기관 오프콤 보고서 등의 문헌을 분석하며, BBC 디지털 채널 편성의 양적 내용 분석 방법론을 이용했다. 연구 결과, 전략의 근간이 되는 ‘더 작은 BBC로’, ‘양질의 콘텐츠로 역량 집중’, ‘디지털 시대의 대비’는 비교적 성공적으로 이행되고 있으며, BBC의 교육, 정보 전달, 오락이라는 방송 철학의 본질은 변하지 않은 채 진화하는 것으로 나타났다. 대시청자 관계에서 시청자를 참여자로 인식하는 사고의 전환, ‘360도 접근 방식’을 통해 ‘기존 방송 개념을 초월’한 맞춤형 온 디맨드 서비스 제공, 경영의 효율성과 투명성 극대화를 위한 노력 등은 사고와 문화, 구조를 개혁하려는 BBC의 의지를 보여준다. 그러나 ‘양질의 콘텐츠로’ 선택적 역량집중이라는 부분에서 여전히 채널 간 콘텐츠의 차별화, 특히 최근 논란이 되고 있는 디지털 채널 BBC3와 BBC4의 운영상 효율성에 문제가 있는 것으로 나타났다. 이는 BBC 트러스트의 중간보고서에서 취약하게 다루어진 부분으로, 내용 분석 결과 BBC3는 지나친 상업성, BBC4는 BBC2와의 차별화 부족이라는 공영방송의 딜레마 문제를 안고 있음이 드러났다. BBC의 사례는 최근 국내의 수신료 인상 논란에 대해, 수신료 인상은 투명한 경영과 개혁을 위한 부단한 노력으로 수신료 수입을 정당화해야 하는 의무를 필연적으로 동반한다는 교훈을 준다. 이 연구는 BBC가 새로운 미디어 환경이라는 위기를 기회로 삼아 개혁과 진화를 계속할 것이라고 결론을 내린다. This study examines the performance and implications of BBC’s ‘Delivering Creative Future’ strategy, unveiled in 2006. There have been a number of researches and debates about the dilemma and the steady demise of the public service broadcasting in the multi channel digital era. The world’s oldest public service broadcaster BBC, once described as Britain’s gift to the world in the 20th century, has been developing the survival strategy, balancing its public service obligations and efficient management. This study considers the way in which the old ‘Reithian’ manifesto ― to educate, to inform and to educate ― has been redefined in this process. The key to ‘Delivering Creative Future’ is ‘Smaller BBC, focused on quality, ready for digital’ and this study analyses these aspects, through literature review, contextual analysis and quantitative analysis, based on BBC documents, press releases, BBC web sites and blogs, government policy documents, BBC Trust publications and Ofcom reports from 2003 and 2010. In particular, BBC Trust’s 2010 Strategy Review and Initial Conclusions have been analysed in depth and it was found that there was insufficient discussion and evaluation of BBC digital channels. It is therefore hoped that the original findings and discussion in this study regarding BBC3 and BBC4 will fill this lacuna and shed light on the debate about future of those two channels and BBC’s overall contents strategy. It concludes that the above strategy has been carried out successfully in terms of providing ‘value for money’ for licence fee payers through setting on example on pay and increasing transparency. A particular success turns out to be BBC’s iPlayer; however, on the other hand, providing ‘high quality, public service contents’ and differentiation between various channels are the immediate challenges.

위기청소년 통합지원체계(CYS-Net) 운영평가 연구

김동일(Dong Il Kim),윤현선(Hyun Sun Yoon),서창원(Chang Won Seo),최수미(Su M Choi) 한국상담학회 2008 상담학연구 Vol.9 No.4

CYS-Net(Community Youth Safety Net) is a community-based system which is composed of various institutes and facilities in respective area cooperating and delivering various services to youths at risk as soon as possible. In other words, CYS-Net is an useful system to guide and care youths at risk so as that those youths can integrate into the society. Counselors deliver crisis interventions, medical and legal services, various guidance for youth activities, as well as counseling services in CYS-Net. Ever since CYS-Net service has been introduced in 2006, the width of the service is on a continual growth. It is important to grasp the present condition of the youth support centers` counselors in the cities, province(Do) and those in the cities, countries(Gun), and districts(Gu), who give CYS-Net service to youths directly, to understand the youth counseling in Korea. The questions of this study are as follows. how does the CYS-Net evaluation vary in accordance with the counselors who provide CYS-Net service, i.e. the youth support centers` counselors in the cities, province(Do) and those in the cities, countries(Gun), and districts(Gu)? The data, composed of 20 questions, were collected from counselors working at youth counseling centers nationwide. The number of observations is 554. This thesis reports frequencies, t-test, repeated measures of ANOVA. The evaluated differences of counselors between the youth support centers in the cities, province(Do) and in the cities, countries(Gun), and districts(Gu) were statistically significant. In other words, the youth support centers` counselors in the cities, countries(Gun), and districts(Gu) think more negatively than those in the cities, province(Do). The results are compatible with KYCI (2006)`s study that the youth support centers in the cities, countries(Gun), and districts(Gu) should be expanded to provide CYS-Net service properly.
