수포성 유천포창과 후천성 수포성 표피박리증에서의 자가항체 침착상

Backgraund : Most of the inflammatory bullous lesions in bullous pamphigoid(BP) and epidermolysis bullosa acquisite(EBA) demonstrate similar clinical and histological features. However, the specificities of the autoantibodiea reactive to the dermo-epidermal junction antigeins are different. In these two bullouk dermat loses, there are no remarkable differences in symptomaiology, there are no unique predilection sites for the lesions and they do not usually leave scars after nvolution. Considering these similarities, dermatologists could encounter some clinical confuiion in maling a provisional diagnosis. Objective : Authors examined three patients of BP with classic inflammatory bullous eruptions and threa patients of EBA with inflammatory bullous lesions to see if here were any differences in the morphology of the immuno-fluorescence(IF) pattern. Methods : For direct IF of vertical or semi-vertical sections, perilasional skin was obtained in each patient for indirect IF of horizontal or semi-horizonta1 sections, Ig(bound substrates were prepared from all these autoantibody-positive individuals. All specimens veri; observed at 200/400-magnification fields through an ordinary fluorescence microscopy. Reaults : Patterns of fluorescence observed by direct IF were characterized as thin-linear in BP and thick/coarse-linear in EBA along the basement membrane zone. On the horizontal section preparations in indirect IF, the patterns of fluorescence were clean-linear in E3P hnd more fluffy-linear in EBA at the dermoepidermal junction, These patterns could be recognized aim/larly in the fields of both 200 and 400-magnification, however each minor differences were not easy to distinguish each other. Conclusion : The above findings of subtle differences in the pattern of IF may provide some suggestions to the examiners for the need of differential diagnosis in theae riseases.

터치스크린을 이용한 터치 위치기반 사용자 인증

김진복(Jin-Bok Kim),이문규(Mun-Kyu Lee) 한국정보보호학회 2011 정보보호학회논문지 Vol.21 No.1

최근 다양한 기능을 탑재한 모바일 장치가 보급되고 개인정보를 다루는 각종 응용들이 등장하면서 사용자에 대한 인증이 중요한 이슈가 되고 있다. 본 논문에서는 기존의 PIN 방식과 더불어 터치스크린 상에서 입력을 하였을 때 얻을 수 있는 터치 위치데이터를 인증에 이용하는 터치 위치기반 인증방법을 제안한다. 본 연구에서 제안하는 방식은 키패드를 이용하는 기존의 PIN 입릭 방식과 동일한 인터페이스를 이용하므로 호환성을 제공하며, 기존 PIN 입력 방식의 안전성을 높이는 방법 중 하나인 행위 분석 방식에 비해 사용자 등록 단계가 간소화되어 편의성을 제공한다. 사용자 인증 실험 결과에 의하면 서로 다른 사용자가 같은 PIN 및 전화번호를 입력한다고 가정할 때 4자리 6자리 PIN 및 11자리 전화번호에 대해 각각 8.1%, 6.2% 8.1%의 EER을 나타내었으며, 이를 사용자마다 다른 PIN 및 전화번호를 사용하는 상황에 적용하면 매우 높은 사용자 인식 성능을 보장할 수 있다. 또한 기존 PIN 입력 방식과 동일한 크기의 패스워드(PIN) 탐색 공간을 갖도록 파라미터를 설정한 후 수행한 공격 실험에 의하면 같은 안전성을 가지는 기존의 PIN 입력 방식에 비해 제안한 방식이 매우 높은 안전성을 가짐을 확인할 수 있었다. Recent advances in mobile devices and development of various mobile applications dealing \vith private information of users made user authentication in mobile devices a very important issue. This paper presents a new user authentication method based on touch screen interfaces. This method uses for authentication the PIN digits as well as the exact locations the user touches to input these digits. Our method is fully compatible with the regular PIN entry method which uses numeric keypads, and it provides better usability than the behavioral biometric schemes because its PIN registration process is much simpler. According to our experiments, our method guarantees EERs of 12.8%, 8.3%, and 9.3% for 4-digit PINs, 6-digit PINs, and 11-digit cell phone numbers, respectively, under the extremely conservative assumption that all users have the same PIN digits and cell phone numbers. Thus we can guarantee much higher performance in identification functionality by applying this result to a more practical situation where every user uses distinct PIN and cell phone number. Finally, our method is far more secure than the regular PIN entry method, which is verified by our experiments where attackers are required to recover a PIN after observing the PIN entry processes of the regular PIN and our method under the same level of security parameters.

We report the clinical evolution of two elderly male patients with extramammary Paget's disease who were treated with radiotherapy. Both cases primarily involved the scrotum and penie root, and were not associated with any underlying or visceral malignancy. The total doses administered were 6000 cGy and 3000 cGy, respectively. A good clinical response was achieved effects were observed. The patients are being followed for any signs of recurrence and have been completely asymptomatic to date

음향 주파수 분석을 이용한 스마트폰 사용자 인증

김진복(Jin-Bok Kim),송정은(Jeong Eun Song),이문규(Mun-Kyu Lee) 한국정보보호학회 2012 정보보호학회논문지 Vol.22 No.2

본 논문에서는 스마트폰에 내장되어있는 다양한 장치들 중 가장 기본적인 장치인 마이크와 스피커를 이용한 사용자 인증 방법을 제안한다. 제안 방법은 음향 채널을 통해 챌린지를 전달함으로 인해 인증 대상이 사용 대상 장치로부터 근거리에 위치함을 보장할 수 있다. 본 논문에서 제안하는 인증 방법은 두 가지로, 스마트폰을 일종의 하드웨어 토큰으로 활용하여 고정시스템 또는 웹사이트 등에 로그인하는 방법과 스마트폰을 사용하고자 하는 사용자가 스마트폰에 로그인하기 위해 가까운 고정 PC를 토큰으로 활용하는 방법이다. 특히 제안 방식은 일반적으로 사용하는 마이크와 스피커를 이용함으로써 추가적인 장치가 필요 없으며 간단한 조작만으로 인증을 수행 할 수 있어 노약자나 장애인 등이 쉽게 사용할 수 있다. In this paper, we propose user authentication methods using a microphone and a speaker in smart phones. The proposed methods guarantee that the user is located close to the target device by transmitting the challenge via an audio channel. We propose two authentication methods; user authentication for a PC or a website using a smart phone as a hardware token, and user authentication to log on to a smart phone using a PC as a token. Because our methods use typical peripheral devices such as a microphone and a speaker, they do not require any special-purpose hardware equipment. In addition, the elderly and the handicapped can easily use our methods because the methods are activated by simple operations.

Background: The incidence of skin diseases in the university hospital cannot be a true indication of their prevalence in the population, but it offers the only available source of information on the their ecology. Objective and Methods : To study the prevalence of common dermatoses and compare these to previous reports, we reviewed 67,924 new outpatients who visited the dermatology clinic at Hanyang University Hospital in Seoul from Jan. 1st, 1981 to Dec. 31st, 1990. Results : The results of the study are summarized as follows : 1. Among the 67,924 outpatients, the number of male patients was 32,812(48.4%) and female patients 35,112(51.6%). 2. Age distribution of patients were 17,883(26.3%) in the 3rd decade, 13,319(19.6%) in the 1st decade, 11,678(17.2%) in the 4th decade, 9,884(14.6%) in the 2nd decade in order. 3. The distribution of dermatoses as disease groups were eczema(23.9%), urticaria-drug erup-tion(13.2%), skin appendage disorder(12.9%), dermatophytosis(11.1%), viral infection(7.7%), disease due to animal parasi es(5.7%), and bacterial infection(3.8% ). 4. The 15 most common dermatoses were dermatophytosis(10.1%), contact dermatitis(8.8%), urticaria(7.8%), acne vulgaris(6.6%), other eczemas(6.5%), atopic dermatitis(5.0%), bacterial infections(3.8%), scabies(3.7%), seborrheic dermatitis(3.6%), drug eruptions(2.9%), verruca(2.1%), herpes zoster(1.9%), psoriasis(1.7%), syphilis(1.5%), and vitiligo(1.4%), 5. Those dermatoses which showed an annually increasing tendency were acne vulgaris, urticaria, contact dermatitis, seborrheic dermatitis, and those of decreasing tendency were scabies, bacterial infections, syphilis, and vitiligo. 6. Dermatophytosis, urt caria, bacterial infection, seborrheic dermatitis, verruca, and vitiligo occurred frequently during the summer. The incidence of other eczemas, scabies, atopic dermatitis, and her pes zoster increased during the winter, 7. In sexual distribution, dermatophytosis, scabies, seborrheic dermatitis were more frequent in the males, whereas contact dermatitis, urticaria, other eczemas, acne vulgaris, and herpes zoster were more frequent in the females. 8. In age distribution, atopic dermatitis and bacterial infections were the most frequent in the 1st decade. Acne vulgans, syphilis, psoriasis, verruca, and dermatophytosis were the most frequent in the 3rd decade, with scabies and vitiligo in the 2nd decade, and herpes zoster in the 7th decade. Conclusion : The distribution of skin diseases in our hospital showed similar with reported studies in other areas. Comparing these results with an Bang's report 10 year ago in Seoul, there was relative high incidence of viral infections compared to the low incidence of bacterial infections.
