MPEG-21의 DRM 기술 표준화 현황 분석

정상원,Jeong, Senator 한국과학기술정보연구원 과학기술정보센터 2004 Journal of Information Science Theory and Practice Vol.35 No.2

MPEG-21 is an open standard framework for creation, delivery and consumption of digital content in interoperable and rights-managed and protected way. Focusing on DRM technologies, this paper covers with concept and ongoing activities of MPEG-21's parts - Digital Item Declaration which is the base unit of trade and delivery, Digital Item Identification, Intellectual Property Management & Protection, Rights Data Dictionary, Rights Expression Language, Persistent Association Technology, Event Reporting, and so on. MPEG-21은 상호운용성이 확보되고 저작권이 보호되는 방법으로 디지털 콘텐츠가 생성, 배포, 소비될 수 있도록 하기 위한 개방형 표준 프레임워크이다. 이 글은 DRM 기술을 중심으로 MPEG-21의 각 분야별-거래와 배포의 기본단위인 디지털 아이템 선언(DID), 디지털 아이템 식별(DII), 저작권 관리 및 보호(IPMP), 권리데이터사전(RDD), 권리표현언어(REL), 영구연결기술(PAT), 이벤트 리포팅(ER)-기술 표준화의 개념과 내용을 살펴본다.

공정의 선후행관계를 이용한 공종 이미지 분류 성능 향상

정상원,정기창,Jeong, Sangwon,Jeong, Kichang 한국건설관리학회 2021 한국건설관리학회 논문집 Vol.22 No.1

이미지를 이용해 공종을 분류하는 작업은 건설 관리와 공정 관리와 같은 더욱 복잡한 어플리케이션에서 중요한 역할을 수행할 수 있다. 하지만, 공사 현장에서 수집한 이미지들은 항상 깨끗하지 않을 수 있고, 이와 같이 문제가 있는 이미지들은 이미지 분류기의 성능에 부정적인 타격을 입힐 수 있다. 이러한 가능성은 공종을 판별하는 시스템을 보조할 수 있는 데이터나 방법의 필요성을 부각한다. 본 연구에서 우리는 공종의 선·후행 관계를 이용해 이미지 분류기를 보조하여 공종을 판별하는 시스템의 성능을 높이는 방법을 제시한다. 그리고 제시하는 방법이 공종 판별의 성능을 향상시킬 수 있다는 것을 보인다. 특히, 이미지 판별기의 성능이 좋지 않을때 더욱 드라마틱한 성능의 향상을 경험할 수 있다는 것을 알 수 있었다. Classifying work trades using images can serve an important role in a multitude of advanced applications in construction management and automated progress monitoring. However, images obtained from work sites may not always be clean. Defective images can damage an image classifier's accuracy which gives rise to a needs for a method to enhance a work trade image classifier's performance. We propose a method that uses work dependency information to aid image classifiers. We show that using work dependency can enhance the classifier's performance, especially when a base classifier is not so great in doing its job.

선상 IgA 수포성 피부병

정상원 ( Sang Won Jeong ),이상원 ( Sang Won Lee ),차승훈 ( Seung Hoon Cha ),박석돈 ( Seok Don Park ) 대한피부과학회 1998 대한피부과학회지 Vol.36 No.5

We describe an 18-year-old male with generalized pruritic, tense annular or polycyalic blistera on normal-appearing skin or erythematous bases. Histopathological fmdings of an iatact early blistering showed subepidermal blistering and papillary neutrophilic gnicroabscesses. A direct immunofluctescent study of a section from the skin adjacent to a lesioti revealed linear deposits of IgA at the dermoepidermal junction. There were no deposits of IgG, lgM, or C3. In 1.0M NaC1 eplit skin, IgA was found to be bound linearly on the epidermal roof. The patient respmded weIl to eteroid and dapsone therapy. (Korean J Dermatol 1998:36(5): 962-964)

Background:Dermatologic patients need advice on how much ointment or cream to apply, in particular topical corticosteroids. The instructions given to patients concerning topical therapy are frequently vague. Objective:The aims of this study are to make simple guidelines on the topical application of ointments or creams for patients, parents, doctors and nurses, and to check the accuracy of these guidelines in practice. Methods:The average height and weight according to the different age groups and sex were measured from Korean standard growth and developement chart. From this chart, their total body surface areas(BSA) were calculated using a standard nomogram. The length of the tips of their index fingers was measured; measuring from the distal skin-crease to the end of the finger. One finger-tip unit(FTU) was defined as the amount of ointment expressed from a tube nozzle with a 5 ㎜ in diameter, covering from the distal skin-crease to the tip of the palmar aspect of the index finger. The average area of abdominal skin covered by one finger-tip unit, and that of one palm were measured by computer scanner(Hurapack scanner, 4C) and image analyzed program(Image Pro. Plus V. 3.0, Micromedical). Each patient then placed his or her right hand lightly, palm side down with the fingers and thumb closed, onto Hurapack scanner 4C. A tracing of the outer edge of the hand was made from the ulnar to radial styloid by photoshop program. The outlined area and enclosed area were measured by an image analyzer. Results 1. The average length of each finger-tip was 2.48±0.2㎝ in males and 2.24±0.13㎝ in females. 2. The average weight of one FTU was 0.46±0.03g in males and 0.40±0.02g in females. 3. The average area of palm was 145±12.4㎠ in males and 115.9±10.1㎠ in females. 4. The average area of abdominal skin covered by one FTU was 278±34.4㎠; The average area was 303±24.3㎠ in males and 253±21.9㎠ in females. (Korean J Dermatol 2000;38(12):1624~1629) 5. The number of FTU of adult male required to treat various anatomical sites was : face and neck, 2.6; trunk and buttock, 10.5; arm and hand, 5; leg and foot, 10. The number of FTU of adult female was : face and neck, 2.8; trunk and buttock, 11; arm and hand, 5.5; leg and foot 11. 6. The number of FTU of children required to treat each anatomical site was variable because of differential growth according to different age. Conclusion:The concept of FTU provides convenient means of rapidly assessing the approximate amount of ointment or cream required for the treatment of patients.

In this study, the teenage room styles were typed through systematic process. Thus, teenage room styles were classified into six types: modern, romantic, casual, industrial, funky, and natural style. The characteristics of each style shown in the teenage room are as follows. The modern style was expressed with a moderation of decorative elements. And the shape of furniture was straight and simple. Also, the achromatic color was used as dominant color, and the accent color of high chroma was used in the fabric or props. The romantic style was decorated with excessive decoration, soft and bright colors were used to create a feminine atmosphere. In the furniture, the expression of curvilinear form was prominently expressed. In casual style, the primary color was used mainly, and the atmosphere with the active feeling was produced. In some cases, patterns of geometric expression were used in fabrics and walls, and some patterns of modern style appeared in furniture. The industrial style consists of mass-produced products, including prefabricated panel ceilings, pipes, metalwork, and bricks, throughout the interior components. In addition, old wood or iron were used, and a vintage atmosphere was also created. In the funky style, graffiti and contrasting paintings were painted on walls and small items, creating an exhilarating atmosphere. A non-formal expression was identified in the overall aspect of the interior components. Natural style used wood material in furniture and floor. In color, white, oak and beige colors were mainly used.

A 40-year-old female patient, known angiocenteric T-cell lymphoma on nasal cavity, was transfered from the department of hemato-oncology for the evaluation of egg sized pinkish-yellow indurated mass with central necrotic tissue on the left medial elbow. Histopathologic findings revealed angiocentric, angioinvasive, and angiodestructive infiltrate containing atypical lymphocytes. The infiltrative cells were positivly stained with antibody to CD45RO, LCA, but not with antibody CD20. The atypical infiltrated perivascular lymphoid cells were positive to Epstein-Barr virus in situ polymerase chain reaction. She was treated with combined chemotherapy and radiation therapy, but she died due to sepsis. We herein report a rare case of angiocentric T-cell lymphoma on the nasal cavity and skin associated with Epstein-Barr virus. (Korean J Dermatol 2000;38(2):240~244)
