The purpose of this essay is to check what are the problems of the current Korean independent films and to find the solutions for effective circulation of the Korean independent films in terms of its intimacy to public. For this, I would like to define 'independent film' and 'its ambiguous distinction', and then I presented the current issues of the Korean independent films and suggested the alternatives of the effective circulation of its production and distribution. Independent films can be defined through our understanding and identification, and it is significant of mutual communication with the audience, so that I will classify the cases of box office of the independent films. The effectiveness of production can be suggested by lower budget and many financial supports, and the effectiveness of distribution is to have many occasions to release, to benefit with them and to release in many festivals. The effort of independent filmmakers, mutual communication between filmmakers and the audience, and the official supporting system will make it possible for effective production and distribution. With this possibility, the future of Korean independent film will be bright.

In 1977, Robinson & Martinez described a distinct varient of ameloblastomas in which the response to curettage was found to be favorable, with a recurrence rate of 25%. They referred to this varient as unicystic ameloblastoma. Unicystic ameloblastoma occur most commonly in the second and third decades of life, which is considerablly younger than the average age of discovery for the classical ameloblastoma. For the accurate histopathological diagnosis of the unicystic ameloblastoma, the specimen obtained the excisional biopsy, complete enucleation or incisional biopsy from the multiple site of the lesion. The purpose of this report is to review of the literature and to present three cases in which an unicystic ameloblastoma appear to be arising in the wall of a dentigerous cyst.

The range data acquired by 2D/3D LIDAR, a core sensor for autonomous navigation of an unmanned ground vehicle, is effectively used for ground modeling and obstacle detection. Within the ambiguous boundary of a road environment, however, LIDAR does not provide enough information to analyze the traversable region. This paper presents a new method to analyze a candidate area using the characteristics of LIDAR reflectivity for better detection of a traversable region. We detected a candidate traversable area through the front zone of the vehicle using the learning process of LIDAR reflectivity, after calibration of the reflectivity of each channel. We validated the proposed method of a candidate traversable region detection by performing experiments in the real operating environment of the unmanned ground vehicle.

The purpose of this study is to estimate convergence level of digital device and service and analyze group difference of consumption behavior and problem according to digital convergence level. The research method was survey with digital business expert and 343 samples. ANOVA research method was applied. The results of research are as follows. First, the study suggests that with a self-directed consuming attitude associated with both online and offline, there are the possibility to spread social problem which has unclear boundary, the possibility of intrusion into privacy through the network flow, and the matter of the credibility of information in convergence media. Second, since digital devices are important to connect consumers to the network, consumers have anxious dependence on the devices, which causes the fatigue of information to increase rapidly.

국내에서 영한 자동번역 시스템을 1985 년부터 개발한 지 벌써 15년이 흐르고 있다. 15 년의 영한 자동번역 기술개발에도 불구하고 아직도 영한 자동번역 시스템의 번역품질은 40%를 넘지 못하고 있다. 이렇게 번역품질이 낮은 이유는 다음과 같이 요약할 수 있을 것이다. o 입력문에 대해 파싱할 때 오른쪽 경계를 잘못 인식함으로써 구조적 모호성의 발생문제: 예를 들어 등위 접속절에서 오른쪽 등위절이 등위 접속절에 포함되는 지의 모호성. o 번역 단위로써 전체 문장을 대상으로 한 번역패턴이 아닌 구나 절과 같은 부분적인 번역패턴으로 인한 문장 전체의 잘못된 번역 결과 발생. o 점차 증가하는 대용량 번역지식의 구축과 관련해 새로 구축되는 번역 지식과 기구축된 대용량 번역지식들 간의 상호 충돌로 인한 번역 품질의 저하. 이러한 심각한 원인들을 극복하기 위해 본 논문에서는 문틀에 기반한 새로운 영한 자동번역 방법론을 소개하고자 한다. 이 문틀에 기반한 영한 자동번역 방법론은 현재 CNN뉴스 방송 자막을 대상으로 한 영한 자동번역 시스템에서 실제 활용되고 있다. 이 방법론은 기본적으로 data-driven 방법론에 속하다. 문틀 기반 자동번역 방법론은 규칙기반 자동번역 방법론보다는 낮은 단계에서 예제 기반 자동번역 방법론보다는 높은 단계에서 번역을 하는 번역방법론이다. 이 방법론은 영한 자동번역에 뿐만 아니라 다른 언어쌍에서의 번역에도 적용할 수 있을 것이다.

우리나라 뿐만 아니라 세계 각지에서 태풍이나 집중호우로 인한 침수피해가 증가하고 있다. 그 원인으로는 수공구조물의 설계빈도를 초과하는 강우, 도시지역 확장으로 인한 불투수지역의 확대, 배수시설의 용량부족 등이 있다. 본 연구에서는 수치지형도, 토양도, 토지이용도 등 누구나 쉽게 구할 수 있는 자료를 이용하여 홍수로 인한 피해가 발생하기 쉬운 지역을 선별하고자 하였다. 우선 강우가 지표면에 도달하게 되면 지표면의 경사, 토양의 특성, 토지이용 등에 영향을 받아 침투되지 못하고 표면에 고이게 되는데 이를 유출생성지도로 표현하였다. 그리고 이렇게 생성된 표면유출수가 지표면의 경사, 지표면의 요철(凹凸), 도로나 철도 등의 인공선형축 등에 영향을 받아 흐르기 쉬우며 이를 유출이동지도로 표현하였다. 또한, 이동된 유출수가 고이기 쉬운 저지대, 지표면의 요철 등으로 인해 누적되는 유출누적지도로 표현하였다. 유출생성지도는 이동, 누적지도의 입력자료가 되어 상류의 유출생성의 정도가 하류지역에 영향을 주도록 하였으며, 최종적으로 유출이 동지도와 누적지도가 실제 침수흔적도와 얼마나 일치하는지 확인하기 위해 서울시 침수흔적도와 비교하였다. 기존의 재해 지도를 얻기 위해서는 강우량을 조사하여 수치모형에 입력함으로써 1차원 또는 2차원의 침수예상도를 작성하는 반면에 본 연구에서는 지형 정보만을 가지고 취약지구를 선정하기 때문에 유역전체 또는 시, 도 단위로 광범위한 연구 영역에 적용이 가능하다. 또한, Spatial MCDM 등을 통해 여러 Raster 자료를 하나의 지표로 나타내기보다 유출수가 생성(또는 이동, 누적)되기 쉬운 지역을 1, 그렇지 않은 지역은 0으로 표현하는 이분법적 분석을 통해 가중치설정과 모호한 경계의 처리 때문에 사용자 및 자료에 따라 취약한 지역이 달라지는 것을 방지하고자 하였다. 이를 통해 표면 유출수로 인해 침수피해가 발생하기 쉬운 지역을 홍수취약지구로 선정하여 침수재해 중점관리 우선순위가 될 수 있도록 하였다.

This study is a secondary data analysis to investigate the nursing tasks performance, appropriate performer, and job satisfaction in the general wards with sift work. We found that nurses performed direct (45%) and indirect nursing (55%). The workload per shift was 37.2% in the day, 35.6% in the evening, and 27.2% at night. The tasks performed after handover were 'direct nursing (34.5%)' and 'documentation and notification (25.8%)'. Nurses responded that there were some tasks that could be delegated to nursing assistants or had ambiguous boundaries with other medical personnel. There was a significant correlation between compliance to the job description of the night shift and job satisfaction (rs=.43, p=.01). These results imply that it is necessary to establish strategies that will enhance work efficiency based on job analysis by shift work, reduce handover time using EMR system, stmart devices, and clarify appropriate performers.

In order to detect an object in yolv5, a process of annotating location information on an existing image is required when learning an image. The most representative method is to draw a bounding box on an image to store location information as meta information. However, if the boundary of the object is ambiguous, it will be difficult to make a bounding box. A representative example would be to classify parts that are not fire and parts that are fire. Therefore, in this paper, images of 100 samples judged to have caught fire were learned by varying the number of boxes. The results showed better fire detection performance in the model where the bounding box was trained by annotating it with three boxes by segmenting it slightly more than annotating it with one box by holding the edge as large as possible during annotating it with one box.

Modern optical mechanisms slanted toward Ocular-centrism have neglected diverse functions of vision, judged objects in abstract and binary perspectives, and organized spaces accordingly, there by neglecting the function of eyes groping objects. Recently, various experiences have been induced through communication with other senses by the complex perception beyond the binary perception system of vision. Haptic perception is dynamic vision that induces accompanying bodily experiences through interaction among the various senses; it recognizes the characteristics of material properties and various sensitive stimulations of human beings. This study elaborates on the major features of haptic perception by examining the theoretical background of this concept, which stimulates the active experience of the subject and determines how characteristics of haptic perception are displayed in picturesque gardens. In order to identify the major features of haptic perception, this study examines how Adolf Hildebrand's theory of vision is developed, expanded, and reinterpreted by Alois Riegl, Wilhelm Worringer, Walter Benjamin, Maurice Merleau Ponty, and Gilles Deleuze in the histories of philosophy and aesthetics. Based thereon, the core differences in haptic perception models and visual perception models are analyzed, and the features of haptic perception are identified. Then, classical gardens are set for visual perception and picturesque gardens are set for haptic perception so that the features from haptic perception identified previously are projected onto the picturesque gardens. The research results drawn from this study regarding features of haptic perception presented in picturesque gardens are as follows. The core differences of haptic perception in contrast to visual perception can be summarized as ambiguity and obscureness of boundaries, generation of dynamic perspectives, induction of motility by indefinite circulation, and strangeness and sublime beauty by the impossibility of perception. In picturesque gardens, the ambiguity and obscureness of boundaries are presented in the irregularity and asymmetric elements of planes and the rejection of a single view, and the generation of dynamic perspectives results from the adoption of narrative structure and overlapping of spaces through the creation of complete views, medium range views, and distant views, which the existing gardens lack. Thus, the scene composition technique is reproduced. The induction of motility by indefinite circulation is created by branching circulation, and strangeness and sublime beauty are presented through the use of various elements and the adoption of 'roughness', 'irregularity', and 'ruins' in the gardens.

In this study, Helikite, Low Altitude Remote Sensing (LARS) platform, was used to acquire coastal images. In the obtained image, the land and water masses were divided using four types of region clustering algorithms, and then waterline was extracted using edge detection. Quantitative comparisons were not possible due to the lack of in-situ waterline data. But, based on the image of the infrared band where water masses and land are relatively clear, the waterlines extracted by each algorithm were compared. As a result, it was found that each algorithm differed significantly in the part where the distinction between water masses and land was ambiguous. This is considered to be a difference in the process of selecting the threshold value of the digital number that each algorithm uses to distinguish the regions. The extraction of waterlines through various algorithms is expected to be used in conjunction with a Low Altitude Remote Sensing system that can be continuously monitored in the future to explain the rapid changes in coastal shape through several years of long-term data from fixed areas.
