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)

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.

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.

Background: Although sunscreen is used as a primary strategy for the prevention of sunburn, photoaging, and skincancer, few people regularly use sunscreen. Objective: To investigate awareness regarding the effects of sunlight, the extent of sun exposure, and sunscreen usebehaviors in Korean subjects. Methods: A questionnaire was administered to 467 adult patients who visited the Dermatology Department at SeoulNational University Boramae Hospital. The questionnaire covered demographic characteristics, causes of wrinkles,sunspots, and skin cancer, awareness of the harmful effects of sun exposure, perceived and actual extent of sunexposure, and the use of sun-protective methods including sunscreen. Results: Sun exposure was selected as the major cause of age spots (60.6%), skin cancer (60.9%), and wrinkles(25.9%). Respondents were likely to underestimate the extent of sun exposure. On average, quite a few respondentsstated that they were exposed to sunlight for more than one hour per day (22.7% on weekdays, 52.4% onweekends). However, only 9.4% of respondents thought that their sun exposure was problematic and 62.7% ofrespondents considered moderate sunlight exposure healthy. Respondents`` sun-protective behaviors were inadequate:only 29.8% used sunscreen regularly, and 16.5% have never used sunscreen. SPF was the most important factor inchoosing sunscreen, and 83.3% used a sunscreen with a labeled SPF over 30. By contrast, only 34.6% ofrespondents used PA+++ sunscreen. Conclusion: Despite fairly good knowledge regarding the harmful effects of sunlight, subjects underestimated therisks of their sun exposure and sun-protective behaviors were suboptimal. Education on the risk of UV exposure andeffects of sunscreen is still needed. (Korean J Dermatol 2015;53(1):16∼22)

Teaching Korean as a Foreign Langugae, 40,245~275. The present study is designed to examine the sociolinguisitoc profile of heritage language learners in English speaking countries according to their Korean language proficiency.According to the results of the interviews, it appears that the entire group of language learners have positive attitude toward learning Korean language and culture. The results also show that they are maximizing both their integral and instrumental motivation. However some significant differences were found between identity, linguistic surroundings and linguistic needs based on their Korean language proficiency. It was found that beginning-level learners used their heritage language less at home and barely had access to Korean speaking environments. In addition, they often had their external identity formed by other people and their knowledge of Korean culture was superficial.Intermediate learners had a high level of Korean use at home and they constantly had access to Korean through media. They have a solid knowledge of Korean culture and are on the way to building an internalized Korean identity. The study revealed that advanced level learners are constanly connected to Korean language and culture not only domestically but also through media and the local community. They are stable forming their internal identity and have an underlying knowledge of Korean culture.(Yonsei University)

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.
