Background: Although sunscreen is used as a primary strategy to prevent sunburn, photoaging and skin cancer, only a few people regularly use sunscreen. Objectives: To investigate the awareness of effects of sunlight, the extent of sun exposure, and the behaviors about sunscreen uses in Korean. Methods: A questionnaire was administered 255 adult patients visited Dermatology Department at Seoul National University Boramae Hospital. It included questions about the awareness of benefit or harm of sunlight, perceived and actual extent of sun exposure, the use of sun-protective methods including sunscreen. Results: Sun exposure was chosen as the major cause of dyschromia (61.2%), skin cancer (62.8%) and wrinkle (28.6%). Respondents were likely to underestimate the extent of sun exposure. On average, quite a few respondents stated that they were exposed to sunlight more than one hour per day (23.1% on weekdays, 53.4% on weekends). But, only 8.7% thought that their sun exposures were problematic and 62.2% of respondents considered moderate sunlight exposure good for health. People`s sun protective behaviors were inadequate: only 30.8% used sunscreen regularly; 18.4% have never used sunscreen. SPF was the most important factor choosing sunscreen and 86.0% used sunscreen labeled SPF over 30. In contrast, only 40.3% used PA+++ sunscreen. Conclusion: Despite a fairly good knowledge about harmful effects of sunlight, people underestimated the risks of their sun exposure and behaviors were suboptimal.

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)

Case Reports : Basal Cell Carcinoma on the Pubic Area: Report of a Case and Review of 19 Korean Cases of BCC from Non-sun-exposed Areas

( Jin Park ),( Yong Sun Cho ),( Ki Hun Song ),( Jong Sun Lee ),( Seok Kweon Yun ),( Han Uk Kim ) 대한피부과학회 2011 Annals of Dermatology Vol.23 No.3

Basal cell carcinoma (BCC) is one of the most commonly diagnosed malignant skin tumors and develops characteristically on sun-exposed areas, such as the head and neck. Ultraviolet light exposure is an important etiologic factor in BCCs, and BCCs arising from non-sun- exposed areas are, therefore, very rare. In particular, the axilla, nipple, the genital and perianal areas are not likely to be exposed to ultraviolet light; thus, if BCC develops in these areas, other predisposing factors should be considered. Herein, we report a case of BCC arising on the pubic area in a 70-year-old man. We also performed a survey of the literature and discussed the 19 cases of BCC from non-sun-exposed areas reported to date in Korea.

Case Report : A Case of Epstein-Barr Virus-associated Hydroa Vacciniforme

Sun Young Huh,Mira Choi,Kwang Hyun Cho 대한피부과학회 2009 Annals of Dermatology Vol.21 No.2

Hydroa vacciniforme (HV) is a photosensitivity disorder characterized by recurrent necrotic vesiculopapules on sun-exposed areas, which heal spontaneously during adolescence. Recently, an association has been reported between latent Epstein-Barr virus (EBV) infection and atypical HV-like eruption and malignant potential. However, latent EBV infection has also been reported in the setting of typical HV. An 11-year-old girl presented with recurrent, scattered, discrete vesicular eruptions with scarring on the face and the extensor surfaces of both forearms. In-situ hybridization was carried out to detect latent EBV infection. Based on the clinical and histopathological findings, typical EBV-associated HV was suspected.

부모양육태도와 자존감이 학교폭력 가해행동에 미치는 영향 특성화 고등학교를 중심으로 -

본 연구의 주된 목적은 학교폭력 가해 경험이 있는 특성화 고등학교 학생들의 부모 양육태도가 학교폭력 가해 행동에 미치는 영향과, 자존감이 학교폭력 가해행동에 미치는 영향, 부모의 양육태도가 자존감에 미치는 영향 및 학생들의 학교폭력에 대한 인식을 분석하는데 있다. 연구대상은 총 122명으로 학교폭력 가해 경험이 있는 특성화 고등학교 남학생과 여 학생(남자 101명 여자 21명)이었다. 측정도구로는 부모양육태도와 배경정보에 대한 것은 Barber(1997)의 척도를 토대로 문항을 재구성하여 다시 제작한 김해영(2000)의 척도와, 자존감 측정도구로는 Rosenberg(1965)의 자존감 척도를 이춘진, 원호택 (1995)이 번안한 한국판 척도를 사용하였고, 학교폭력 가해 경험은 김준호, 김선애(2003)가 개발하고 김언지 (2004)가 수정 보완한 학교폭력 경험 측정도구 중 가해경험 문항을 사용하였으며, 학교폭력에 관한 인식은 김범수(2009)의 설문을 질적 문항으로 수정 보완하여 사용하였다. 분석 결과는 다음과 같다. 첫째, 부모의 양육태도가 학교폭력에 미치는 영향을 분석해 본 결과, 부모의 양육태도 중에 자율이 높아질수록 학교폭력은 낮아진다고 나타났다. 둘째, 부모의 양육태도가 자존감에 미치는 영향을 분석해 본 결과, 부모의 양육태도 중에 신뢰가 높아질수록 자존감이 높아진다고 나타났다. 셋째, 자존감이 학교폭력에 미치는 영향을 분석해 본 결과, 자존감은 학교폭력에 영향을 미치지 못하는 것으로 응답하였다. 넷째, 특성화 고등학교 학교폭력 가해 경험이 있는 학생들의 학교폭력에 대한 인식을 분석해 본 결과 학교폭력이 매우 심각하다고 가장 많이 응답하였으며, 보통, 미응답, 심각하다의 순으로 나타났다. 학교폭력의 주도적인 해결자로는 당사자가 가장 많은 응답을, 학교, 미응답, 경찰, 친구의 순으로 나타났다. The main purpose of this study is to analyze the impact of parenting behavior on school violence behavior of students of specialized high schools with experience in school violence, the impact of self-esteem on school violence behavior, the impact of parenting attitude on self-esteem, and the perception of school violence on students. A total of 122 students were subject to the study, with boys and girls from specialized high schools (101 men and 21 women) with experience in committing school violence. For measuring instruments, parents' adoptive attitudes and background information are based on Barber (1997), Kim Hae-young (2000) reconstructed and recreated based on Barber (1995), and Rosenberg (1965V s self-esteem measures were used by Lee Chun―jin and Won Ho―taek (1995),while Kim Sun-joon (1995) developed a Korean version of a school violence experience. The results of the analysis are as follows. First,after analyzing the impact of parental attitudes on school violence, it was found that the higher the self-esteem, the lower the school violence. Second, after analyzing the impact of parental attitudes on self-esteem, the higher the level of confidence among parents' attitudes, the higher the level of self-esteem. Third,after analyzing the impact of self-esteem on school violence, the results showed that self-esteem does not affect school violence. Fourth, after analyzing the perception of school violence by students with experience of committing school violence in specialized high schools,the school violence was most said to be very serious, in the order of normal,unresponsive and serious. As the leading solver of school violence, the parties responded the most,followed by schools,non-response, police and friends.

태양돛은 태양 광자들의 운동량 변화를 이용하여 추력을 얻는 우주선이다. 매우 작지만 연속적인 가속도를 얻을 수 있어 태양돛은 다양한 임무를 수행할 수 있다. 효과적인 임무 개발을 위해서는 태양돛의 형상, 돛의 재료 그리고 전개 장치에 따른 구조/재료적 특성뿐만 아니라 위성의 임무 궤적에 따른 자세제어 방법들을 고려해야 한다. 본 논문에서는 태양돛의 기술발전, 태양돛 제작에 필요한 소요기술 그리고 태양돛을 이용한 향후 개발 가능한 위성 임무에 대하여 살펴보고자 한다. Solar sail spacecrafts can gain propulsion using the momentum change through reflecting the photon packets of energy from the Sun. The sail slowly but continuously accelerates to accomplish a wide-range of potential missions. To develop the potential mission of the solar sail, the configuration, the film characteristics and the deployment devices should be carefully considered. In this paper, recent development and activities of the solar sail are introduced and design technology of the sail subsystem is investigated.
