산사태는 지형, 지질, 임상, 토양 등과 같은 다양한 요인들이 복합적으로 작용하여 발생한다. 따라서 산사태 발생위치와 산사태 유발 요인 사이의 상관관계를 파악할 수 있는 다양한 분석 기법이 사용되고 있으며 본 연구에서는 산사태 위험지역을 정량적으로 예측할 수 있는 효과적인 기법을 제안하고자 퍼지관계 기법과 인공신경망 기법을 이용하여 포항지역의 산사태 취약성을 분석하였다. 취약성 분석을 위해 먼저 산사태 위치를 파악하여 현황도를 작성하였으며, 산사태 발생과 관련 있는 11개의 요인들에 대한 공간 데이터베이스를 구축하였다. 퍼지관계 기법에서는 cosine amplitude method를 이용해 각 요인 별 퍼지 소속 함수 값을 획득하고 퍼지관계 함수 연산을 이용하여 취약성도를 작성하였다. 인공신경망 기법에서는 오류 역전파 알고리즘을 이용하여 산사태와 관련 요인들 간의 상대적 가중치를 결정하고 취약성도를 작성하였다. 두 기법으로 도출된 산사태 취약성도의 ROC(Receiver Operating Characteristic)와 AUC(Area Under the Curve)를 통한 검증 결과는 82.18%와 87.4%로 나타났다. 퍼지 관계 및 인공신경망 기법 모두 높은 예측 정확도를 보여 취약성 분석 기법으로서의 적용 가능성이 있는 것으로 분석되었다. 한편 본 연구지역의 경우 인공신경망 기법이 퍼지관계 기법에 비해 좀 더 나은 예측 정확도를 보이는 것으로 분석되었다. Landslides are caused by complex interaction among a large number of interrelated factors such as topography, geology, forest and soils. In this study, a comparative study was carried out using fuzzy relationship method and artificial neural network to evaluate landslide susceptibility. For landslide susceptibility mapping, maps of the landslide occurrence locations, slope angle, aspect, curvature, lithology, soil drainage, soil depth, soil texture, forest type, forest age, forest diameter and forest density were constructed from the spatial data sets. In fuzzy relation analysis, the membership values for each category of thematic layers have been determined using the cosine amplitude method. Then the integration of different thematic layers to produce landslide susceptibility map was performed by Cartesian product operation. In artificial neural network analysis, the relative weight values for causative factors were determined by back propagation algorithm. Landslide susceptibility maps prepared by two approaches were validated by ROC(Receiver Operating Characteristic) curve and AUC(Area Under the Curve). Based on the validation results, both approaches show excellent performance to predict the landslide susceptibility but the performance of the artificial neural network was superior in this study area.

Drug-Induced Sleep Endoscopy: A Guide for Treatment Selection

김진엽,Seung Cheol Han,Hyun Jung Lim,김현직,Jeong-Whun Kim,이재서 대한수면학회 2020 sleep medicine research Vol.11 No.1

Identifying the sites, severity, and pattern of upper airway obstruction in obstructive sleep apnea is crucial for determining the treatment options, particularly the surgical plan. Although early methods of assessment, such as Muller’s maneuver, computed tomography, and magnetic resonance imaging in awake patients have been utilized to assess obstructive sites, the physiologic and anatomical differences between awake and sleeping patients showed a limited ability of those methods as diagnostic tools. Recently, drug-induced sleep endoscopy (DISE) was introduced as a useful diagnostic and evaluation tool to identify dynamic upper airway collapse during sedation that simulates natural sleep. In this article, we review all aspects of DISE, including the technique, evaluation methods, and clinical application.

Kim Jeong-Whun,Kim Hyo sang,Kim Minju,Kim Su Hwan,Cho Sung-Woo,김진엽 대한의학회 2021 Journal of Korean medical science Vol.36 No.6

Background: The patients with coronavirus disease 2019 (COVID-19), a worldwide pandemic infection, frequently complain of olfactory disorders. However, psychophysical olfactory tests performed by an examiner are very difficult in these highly infectious patients. This study aimed to develop and validate a questionnaire for olfactory function that can be readily used to evaluate olfactory loss. Methods: Fourteen smell-related questions were created based on smells familiar to Koreans. Among them, questions with a κ value of 0.6 or higher were finally selected through a test-retest reliability analysis. The correlations between the scores of the olfactory questionnaire and those of olfactory function tests (Butanol Threshold Test [BTT] and Cross Cultural Smell Identification Test [CCSIT]) were analyzed. To evaluate the predictive ability of the questionnaire and elicit cutoff values, receiver operating characteristic (ROC) curves were generated. Results: Out of the 14 questions in the questionnaire, 11 (κ > 0.6) were selected for the olfactory questionnaire. We analyzed 2,273 subjects, and there was a significant correlation between the total score of the olfactory questionnaire and the BTT (r = 0.643, P < 0.001) or CCSIT (r = 0.615, P < 0.001) scores. ROC curves for the olfactory questionnaire, BTT, and CCSIT all demonstrated high predictive power to discriminate anosmia and severe hyposmia from normosmia. Regarding mild to moderate hyposmia, however, ROC curve for the olfactory questionnaire alone showed high predictive power of discrimination from normosmia. Based on the results of ROC curves among the subclasses, we suggest the classification of the total score of the questionnaire as 0–4, 5–17, 18–27, 28–41, and 42–44, for anosmia, severe hyposmia, moderate hyposmia, mild hyposmia, and normosmia, respectively. Conclusion: The total scores of the questionnaires correlated with the BTT and CCSIT scores. The symptom questionnaire for olfactory dysfunction may be useful as an alternative tool for olfactory function testing, when unavailable.

아름다움

김진엽(Kim, Jinyup) 조선대학교 조형미술연구소 2013 조형미술논문집 Vol.13 No.2

In this essay, there will be discussion on what beauty is, especially in the matter of how human beings sense it. Presupposing that there is an innate structure which makes human beings sense beauty, in this essay, I will explore the theory of Hume continuing with the theory of Kant and the evolutionary theory to find out what the structure is. I will also indicate the theory of Dewey as the resolution of the contradiction between the theory of Kant and the evolutionary theory. As a consequence of it, it will be argued that the subjective ability to perceive beauty would be possible to obtain in the state of disinterestedness through the interest. Keywords : 아름다움, 취미, 무관심성, 진화 beauty, taste, disinterestedness, evolution

미술에서의 저작권 문제 - 미술 저작권 적용을 중심으로 -

김진엽 ( Kim Jinyub ) 한국영상미디어협회 2016 예술과 미디어 Vol.15 No.4

저작권법은 저작물을 창작한 저작자의 권리 및 이에 인접하는 권리를 보호하며, 저작물의 공정한 이용을 도모함으로써 문화 및 관련 사업에 이바지한다는 목적을 가지고 있다. 지적소유권으로서 저작권(copyright)은 창작물을 복제(copy) 할 수 있는 독점적인 권리이다. 역사적으로 18세기 초반 서구에서 출판에 대한 보호로 시행된 저작권법은 문화예술 환경의 변화와 기술의 발전에 따라 그 적용대상이 늘어나면서 복합적인 양상을 만들고 있다. 저작권의 보호 체계는 `저작물, 저작자, 저작권, 보호의 제한과 예외, 저작인접권자, 권리 구제` 등으로 구성되어 있다. 이러한 저작권법의 기본 원리는 지식의 성과를 이용하려는 일반 공공의 필요와 저작자에 대한 보호를 통해 창작활동을 자극하려는 것이다. 저작권의 보호는 `독자성, 표현물성, 창작성`의 요건을 충족하여야 한다. 그러나 이러한 요건들을 상황에 따라 분쟁을 야기할 요소가 있다. 특히 미술저작물의 경우 순수미술과 응용미술의 구분이 모호한 경우가 많고, 응용미술의 경우 산업생산물과의 분류의 어려움, 산업디자인을 포함하는 `의장법`과의 충돌가능성 등에서 다양한 해석이 필요한 상황이다. 특히 포스트모더니즘의 주요 흐름의 하나인 패러디의 경우는 `차용미술`을 폭넓게 인정한 경우이지만 저작권의 본래적인 의미를 훼손하는 경우도 발생하는 것이다. 미술에서 저작권 문제는 저작인격권과 저작재산권으로 구분되는데, 문제는 현대미술의 장르 융합과 해체의 상황에 따라 타 분야저작물과의 중복 가능성이 열려 있다는 것이다. 특히 디자인이나 사진, 영상 등 매체의 확산과 문화산업의 주요 콘텐츠를 제공하는 미술의 경우는 향후 저작권 문제에 있어 많은 문제 제기가 따를 것이다. 다른 예술분야와는 달리 미술은 `공공성`의 측면에서 저작물의 전시, 이용 등에 있어서 관대한 편이고 대부분의 작가들은 저작권 침해에 대한 이해가 상대적으로 부족한 편이다. 저작권은 경제적인 이익뿐만 아니라 예술이 가진 사회의 공익적 측면에 주목하는 것이다. 공공성 담론의 예들처럼 예술창작과 그에 대한 보호인 저작권의 범위와 한계 등에 대해서는 앞으로도 꾸준한 논의가 이어져야 한다. Copyright law aims to contribute to improving cultural industry and related businesses by protecting the rights of the authors who produced creative works and the equivalent rights and promoting the fair use of such creations. As intellectural property, copyright refers to a monopolistic right to allow to copy creations. Historically, copyright law, which was enacted to protect publication early in the 18th century in the West has been increasingly applied with the changes in cultural arts environment and the development of technology, which produced complexity. The protection system of copyright consists of `creations, author, copyright, limitation of and exception to protection, owner of neighboring copyright, and protection of right.` The basic principles of this copyright are the necessity of the general public sector to use the outcome of knowledge and the stimulation of creative activities to protect author. The protection of copyright must meet the requirements of `identity, expressionality, and creativity.` However, these requirements have elements to cause disputes depending on situation. Particularly in art creations, the classification into pure arts and applied arts is often ambiguous, and in case of applied arts, various interpretations need to be made because of difficulty in classifying industrial products and possibility to conflict with `design law` including industrial design. Especially in case of parody, one of the major branches of postmodernism, `appropriation art` has widely been acknowledged, but the original meaning of copyright has often been damaged. Copyright issue in art is classified into author`s moral right and copyright, but the problem is that duplication with creations in other fields is open depending on fusion and deconstruction of genes in modern arts. Many problems will be raised in the future copyright issue, for example spread of media such as design, photo, and media and arts providing major contents on cultural industry. Unlike other fields of art, art is tolerant in exhibiting and using creations in terms of `publicness` and most of the authors lack in understanding the infringement of the copyright relatively. Copyright focuses on social publicness of art as well as its economic benefits. As shown in the examples of discourse on publicness, artistic creations, the scopes and limitations of copyright, and protection for publicness are to be discussed steadily in the future.

현대 건축에 나타난 랜드스케이프 건축의 공공공간(公共空間)에 관한 연구

김진엽(Kim, Jin-Youp),김정곤(Kim, Jung-Gon) 한국실내디자인학회 2012 한국실내디자인학회논문집 Vol.21 No.5

This study starts from the question about the possibility of landscape, especially the possibility to give a new vision in the aspect of publicity. Such a concept of landscape architecture made its appearance in the last decade of the 20th century, as the flexible network to include the changes and the specificity of the surroundings, which simultaneously focuses on the temporality-the uncertainty. Moreover landscape architecture can be defined as the architecture in which the interest on human activities lie in the center of the concept. By analyzing concrete examples, the landscape architecture can be defined in 3 aspects : unity of building and nature, void and public space, space of expansion. As a result of the analysis of landscape architects" statements, it can be said that the issues of publicity are always put at the starting point of landscape architecture with its attention to the way to associate an individual with the others.
