본 논문에서는 낮은 대역폭을 가진 모바일 DMB 환경에서 사용할 수 있도록 깊이 영상 기반 렌더링(DIBR) 기법을 이용한 3차원 스테레오 입체 방송의 부가정보 영상 구성 방법을 설명한다. DIBR에서는 좌측 시점의 영상과 깊이 정보를 전송하고 수신측에서 우측 시점을 복원하는데, 화질이 손상될 수 있다. 본 논문에서는 부가 정보를 구성해서 함께 전송하여 복원된 영상의 질을 높이고 전송하는 데이터의 양을 줄이는 방법을 제시한다. This paper presents the delta image composition methods using Depth-Image-Based Rendering (DIBR) for 3D stereoscopic broadcasting for the low bandwidth mobile DMB broadcasting system. With DIBR, a left and depth images are transmitted to a mobile device, which restores the right view, whose quality may be poor. This paper describes delta image composition methods for the restoration while minimizing the amount of the transmitted data.

Pediatric dysphagia comes from disturbances in swallowing process, which has 'preparatory phase', 'oral phase', 'pharyngeal phase', and 'esophageal phase', and mainly the causes are neuro-muscular discoor-dination. It is necessary to recognize clinical manifestation if they have accompanied organic disorder and diagnose accurately. Videofluoroscopic study evaluation is a valuable method to find out abnormal swallowing mechanism at each phases. Treatment should be diagnosis specific, and multidisciplinary team approach is desirable. We can use various behavioral techniques to facilitate normal swallowing mechanism including conditioning of oral and pharyngeal structures, bolus manipulation, postural compensation, and adaptive feeding utensils. Important point is that the diagnosis and treatment for pediatric dysphagia should not be delayed because children are under development.

RF 마그네트론 스퍼터링에 의해 합성된 Nb-doped TiO₂ 투명전극의 특성

김민영,조문성,임동건,박재환,Kim, Min-Young,Cho, Mun-Seong,Lim, Dong-Gun,Park, Jae-Hwan 한국전기전자재료학회 2012 전기전자재료학회논문지 Vol.25 No.3

$TiO_2$ ($Ti_{1-x}Nb_xO_2$, x= 0.04~0.06) transparent conducting oxide film was fabricated by RF magnetron sputtering process and their electrical, optical, stability properties were studied. When the Nb 4 at% sputtering target was used with RF power 120 W, pressure 8 mTorr, post-annealing temperature $600^{\circ}C$, the resistivity of TNO film was $4{\times}10^{-4}\;{\Omega}-cm$. The optical transmittance in the visible wavelength was ca. 86%. TNO films require heat treatment during or after the deposition process. When the film was deposited at room temperature and post-annealed at $600^{\circ}C$, the lowest resistivity was obtained. When the TNO film was exposed to high temperature and humidity, the resistivity of the film was rather decreased. The stability to temperature and humidity implies that the TNO film could be a appropriate candidate for In-free, ZnO-free transparent conducting oxide materials.

Objectives: The purpose of this study was to define the association between the medical utilization of osteoarthritis patient and its related factors. Methods: We used the 2005 Korean National Health and Nutrition Survey data and we enrolled 2833 participants who were forty or older and who were diagnosed as having osteoarthritis by a doctor within 1 year and who had suffered from osteoarthritis for more than 3 months. The Andersen behavioral model was used as the analytic framework, and the variables were categorized into predisposing, enabling, and need factors. To determine the influence of each variable on the medical utilization of osteoarthritis patient, we applied hierarchical logistic regression analysis with two stages: the first stage included the predisposing and enabling factors and the second stage included the need factors. Results: On the hierarchical logistic analysis, the variables of personal income, the type of medical security, the duration of arthritis related symptoms within 1 month, the subjective health status and the duration of osteoarthritis showed a statistically significant association with medical utilization in men. And the variables of age, limitation activity due to osteoarthritis, arthritis related symptoms within 1 month, and the subjective health status had a statistically significant association with medical utilization in women. Conclusions: The patients who tend to receive less care are those who suffer less from symptoms of osteoarthritis, those who are within the initial phase, or those with a low-level severity of osteoarthritis. It is necessary to encourage patients to receive the treatment in the initial phase.

한국 문학 아카이브의 현황과 전망: 근대문학정보센터와 국립한국문학관 설립을 중심으로

김민영,Kim, Min-yeong 한국기록관리학회 2019 한국기록관리학회지 Vol.19 No.4

본 논문은 한국 문학 아카이브의 미래를 탐색하기 위하여, 국립중앙도서관의 근대문학 아카이브를 소개하고 국립한국문학관의 아카이브 추진 방향에 대하여 논의하는 글이다. 국립중앙도서관의 근대문학 아카이브는 근대문학자료 원문 디지털화 및 전문적인 해제 정보 제공, 근대작가 및 근대문학사 관련 콘텐츠 구축 등을 중심으로 운영되고 있다. 2022년 개관을 목표로 하는 국립한국문학관의 문학자료 아카이브는 국립중앙도서관의 사례를 참고하되 보다 전문적인 큐레이션을 도입할 필요가 있다. 즉 아카이브된 자료를 바탕으로 문학의 창조적인 재생산이 가능하도록 기록의 맥락(context)을 기록하는 아키비스트의 태도를 가지고, 자료의 활용성을 확대할 수 있는 적극적인 아카이브 정책을 펼쳐야 할 것이다. To research the directionality of Korean literary archives, this paper introduces the modern literature archive of the National Library of Korea and discusses the future direction of the archive of the National Museum of Korean Literature. The modern literature archive of the National Library of Korea is operated with focus on digitizing the original text of modern literature, providing professional release information, and constructing contents related to modern writers and literary history. As such, the National Museum of Korean Literature, which aims to open in 2023, needs to refer to the case of the National Library of Korea but introduce more professional curating. In other words, the archivist should have the initiative to document the context of the records so that literature can be reproduced creatively based on the archived data. Moreover, he/she should actively implement archive policies to expand the availability of materials.

White organic light-emitting diodes with a structure of indium-tin-oxide [ITO]/N,N-diphenyl-N,N-bis-[4-(phenylm-tolvlamino)-phenyl]-biphenyl-4,4-diamine [DNTPD]/[2,3-f:2, 2-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile [HATCN]/1,1-bis(di-4-poly-aminophenyl) cyclo -hexane [TAPC]/emission layers doped with three color dopants/4,7-diphenyl-1,10-phenanthroline [Bphen]/$Cs_2CO_3$/Al were fabricated and evaluated. In the emission layer [EML], N,N-dicarbazolyl-3,5-benzene [mCP] was used as a single host and bis(2-phenyl quinolinato)-acetylacetonate iridium(III) [Ir(pq)2acac]/fac-tris(2-phenylpyridinato) iridium(III) $[Ir(ppy)_3]$/iridium(III) bis[(4,6-di-fluoropheny)-pyridinato-N,C2] picolinate [FIrpic] were used as red/green/blue dopants, respectively. The fabricated devices were divided into five types (D1, D2, D3, D4, D5) according to the structure of the emission layer. The electroluminescence spectra showed three peak emissions at the wavelengths of blue (472~473 nm), green (495~500 nm), and red (589~595 nm). Among the fabricated devices, the device of D1 doped in a mixed fashion with a single emission layer showed the highest values of luminance and quantum efficiency at the given voltage. However, the emission color of D1 was not pure white but orange, with Commission Internationale de L'Eclairage [CIE] coordinates of (x = 0.41~0.45, y = 0.41) depending on the applied voltages. On the other hand, device D5, with a double emission layer of $mCP:[Ir(pq)_2acac(3%)+Ir(ppy)_3(0.5%)]$/mCP:[FIrpic(10%)], showed a nearly pure white color with CIE coordinates of (x = 0.34~0.35, y = 0.35~0.37) under applied voltage in the range of 6~10 V. The luminance and quantum efficiency of D5 were $17,160cd/m^2$ and 3.8% at 10 V, respectively.
