Background: Although deleterious effects of sunlight have been increased recently, the surveillance of the attitudes toward sun-exposure and the behavioral aspect of using sunscreens in Koreans has hot been carried out. Objective: Our purpose was to evaluate the attitude toward the harmfulness of sun-exposure and behaviors of using sunscreens in Korea. Method: Five hundred and fifty-two subjects were surveyed to assess the attitude toward sun-exposure, as well as the subjects knowledge about, and the use of sunscreens. Underlying data including demographic data, skin colors, skin types, occupation, and sun-exposure, were obtained. Results: Fifty-four percent of subjects believed that sun-exposure is bad for their skins, but, on the contrary, 12.5% believed it to be beneficial. Fifty-two percent of subjects used sunscreens. Almost all subjects(93.8%) knew why to use sunscreens but 62.7% of subjects did not know the meaning of sun protective factors(SPF). Women, indoor workers, subjects less than 40 years old, with less sun-exposed, fair colored skin, or with skin type I, II, III tended to know the deleterious effects of sunlight and the meaning of SPF and used more sunscreen. Conclusion: High risk population-men, outdoor workers, subjects oider than 40 years old, with more sun-exposed, dark colored skin, or skin type VI, V could be targeted with campaigns that promote attitudinal and behavioral changes.

Purpose: Pediatricians have a significant responsibility to educate mothers about the importance of breastfeeding. However, there have been minimal efforts in the courses of resident training in Korea. The purpose of this study is to evaluate the change in knowledge and attitude before and after a 4-week breastfeeding educational intervention among multicenter residents. Methods: Prospective interventional educational research was designed for residents at eight training hospitals in Korea. Institutional reviews were obtained in each hospital. The education curriculum consisted of 14 courses regarding breastfeeding theory and practice. These materials were used to teach pediatric residents for 4 weeks. Knowledge-based tests were administered before the course, and re-tests were administered after the course using different test items of similar levels. Test scores and survey responses were compared before and after the intervention. Results: A total of 73 residents (1st year 20, 2nd year 23, 3rd year 16, and 4th year residents 14) from eight training hospitals completed the intervention. Their average age was 30.3±2.9 years, 17 (23.3%) were male, 22 (30.1%) were married, and eight had more than one child of their own. The mean pre-test score was 61.8±13.4 and the mean post-test score was 78.3±7.5 (P<0.001). The inter-grade difference in the score was significant in the pre-test (P=0.005), but not significant in the post-test (P=0.155). There were more responses of obtaining confidence after the intervention (P<0.001). Conclusion: In our study, pediatric residents showed improvement in their knowledge and confidence level after 4 weeks of the breastfeeding curriculum. This will provide a basis for future policymaking in the training of pediatric residents regarding breastfeedReceived: 6 January 2022 Revised: 15 February 2022 Accepted: 15 February 2022 Correspondence to: Ellen Ai-Rhan Kim, MD Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Korea Tel: +82-2-3010-3390 Fax: +82-2-3010-6978 E-mail: arkim@amc.seoul.kr A Multi-Center Educational Research Regarding Breastfeeding for Pediatrics Residents in Korea Yong-Sung Choi, MD,PhD1, Sung-Hoon Chung, MD, PhD2, Eun Sun Kim, MD, PhD3, Eun Hee Lee, MD4, Euiseok Jung, MD5, So Yeon Lee, MD, PhD5, Wooryoung Lee, MD6, Hye Sun Yoon, MD, PhD7, Yong Joo Kim, MD, PhD8, Ji Kyoung Park, MD, PhD9, Son Moon Shin, MD, PhD9, and Ellen Ai-Rhan Kim, MD, PhD5 1Department of Pediatrics, Kyung Hee University Hospital, Seoul, Korea 2Department of Pediatrics, Kyung Hee University Hospital at Gangdong, Seoul, Korea 3Department of Pediatrics, Kangwon National University Hospital, Chuncheon, Korea 4Department of Pediatrics, Korea University Anam Hospital, Seoul, Korea 5Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea 6Department of Pediatrics, Soonchunhyang University Seoul Hospital, Seoul, Korea 7Department of Pediatrics, Nowon Eulji Medical Center, Eulji University, Seoul, Korea 8Department of Pediatrics, Hanyang University Seoul Hospital, Seoul, Korea 9Department of Pediatrics, Inje University Busan Paik Hospital, Busan, Korea Neonatal Med 2022 February;29(1):28-35 https://doi.org/10.5385/nm.2022.29.1.28 pISSN 2287-9412 . eISSN 2287-9803 Copyright(c) 2022 By Korean Society of Neonatology This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http:// creativecommons.org/licenses/by-nc/4.0), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

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.

Basal cell carcinoma (BCC) is the most common human malignant neoplasm, accounting for 75% of all non-melanoma skin cancer. The incidence of BCC is strongly correlated with sun exposure as well as older age. Therefore, the vast majority of BCCs is observed in elderly patients on the sun-exposed skin of the head and neck with a frequency of more than 80%. BCC is very rare on sun-protected skin such as the perianal and genital regions and other etiologic factors must be considered in these cases. Although the pathogenesis of vulvar BCC is unclear, early diagnosis is very important. Because BCC in these areas sometimes seems innocuous, it is recommended that a biopsy of all suspect lesions be performed. We report a woman with BCC of the vulva treated with wide local resection and reviews the literatures on this subject.

Korea Aerospace Research Institute (KAKI) is developing a Korea Multi-Purpose Satellite I (KOMPSAT-1) which accommodates Electro-Optical Camera (EOC), Ocean Scanning Multi-spectral Imager (OSMI), and Space Physics Sensor (SPS). The satellite has the weight of about 500kg and will be operated on the 10:50 AM sun-synchronized orbit with the altitude of 685 km. The satellite will be launched in 1999 and its lifetime is expected to be over 3 years. The main mission of EOC is the cartography to provide the images from a remote earth view for the production of 1/25000-scale maps of KOREA. EOC collects 510 - 730 nm panchromatic imagery with the ground sample distance(GSD) of 6.6 m and the swath width of 17 km by push broom scanning. EOC also can scan ±45 degree across the ground track using body pointing method. The primary mission of OSMI is worldwide ocean color monitoring for the study of biological oceanography. It will generate 6 band ocean color images with 800 km swath width and 1km GSD by whiskbroom scanning. OSMI is designed to provide on-orbit spectral band selectability in the spectral range from 400 nm to 900 nm through ground command. This flexibility in band selection can be used for various applications and will provide research opportunities to support the next generation sensor design. SPS consists of High Energy Particle Detector (HEPD) and Ionosphere Measurement Sensor (IMS). HEPD has missions to characterize the low altitude high-energy particle environment and to study the effects of radiation environment on microelectronics. IMS measures densities and temperature of electrons in the ionosphere and monitors the ionospheric irregularities at the KOMPSAT orbit.

相動詞의 意味分析

Aspect verbs play the most important role in English aspect and there are begin and start in the ingressive, keep and continue in the continuous, stop and quit in the terminative, and finish, end and complete in the resultative. The verbs under the same category, for example begin and start, are usually understood to have the same meaning for non-native speakers, and two complement forms of these verbs, to V and V-ing, are regared as the paraphrases, There are, however, distinct semantic differences among four sentences below. 1) John started to smote. 2) John started smoking. 3) John began to smoke. 4) John began smoking. The aim of this study is to examine these Semantic differences. TO meet this aim, I studied the deep structure of aspect verbs, investigated the presupposition and consequence of each aspect verb, found out the condition of the cooccurrence with verb type, and examined the form of complements. The result of this study is as fellows ; 1) Aspect verbs usually have polysemy and their deep structures are devided into two ; the transitive analysis with animate agentive subject and intransitive analysis with non-agentive subject. 2) Ingressive aspect has negative presupposition while the others have positive presupposition, and terminative and resultative aspect have negative consequence while the others have positive consequence. 3) Each aspect verb has restriction in the cooccurrence with the complement verb type : ingressive with activities, accomplishment and gradual achivements, terminative with activities and accomplishments, resultative with accomplishments, and continuous with every verb type except states. 4) V- ing has durative meaning of a single event in the single time boundary and to V shows the intermittent occurrence of the same type of events in the different time boundary.
