본 연구는 일반인에게 접근과 해석에 장벽이 있는 수면다원검사 데이터를 바탕으로, 사례분석과 작품 제작을 통해 새로운 형태의 시청각화 방법을 제시한다. 대부분의 예술작품은 깨어있는 동안 행하는 의식적인 행동을 바탕으로 완성된다. 본 작품에서는 수면 중 발현되는 무의식을 관찰하여 이를 예술로 표현하고자 한다. 수면다원검사를 통해 측정된 수면장애 그래프를 중점적으로 분석하여 정상 군과 기면증, 불면증, 수면무호흡증으로 분류했고 습득한 생체데이터를 정제 후 수치화 시켰다. 정제된 데이터는 MAYA를 통해 3D 애니메이션 이미지로 렌더링 했고, 심장박동 데이터 스크립트는 midi형태로 변형시켜 garage band에서 청각화 시켰다. 이후 After Effects로 이미지와 사운드를 결합했다. 총 4개의 는 각각 3분 20초의 싱글 채널 영상으로 제작했다. 는 수면 의학 데이터를 예술로 표현함으로써 난해한 정보를 직관적으로 이해시키는 데에 목적이 있다. 또한 의식적인 활동이 일어나지 않는 수면 상태에서 무의식 데이터로부터 예술 표현의 가능성을 드러내고자 한다.

In this paper, we develop a mobile MAP open API using HTML5 local storage and the W3C geolocation API. The mobile MAP open API consists of the basic JavaScript MAP API, offline navigation API, and multimedia POI (mPOI) API. The basic JavaScript MAP API creates a map and controls, rotates, and overlays data on the map. The offline navigation API is developed using HTML5 local storage and web storage. The mobile web application downloads and stores mPOIs of works of art to local storage or web storage from a web server. The mPOI API is developed using HTML5 video and audio APIs. We develop a mobile art park guidance application using the developed mobile MAP open API.

Adobe Flash는 웹 사이트에서 GIF 애니메이션의 한계를 극복하기 위해 나온 벡터 기반 멀티미어 제작 툴로 기능에 비해 가볍고 사용자와 상호 작용할 수 있는 콘텐츠 저작 도구로 각광을 받아왔다. 그 결과 웹상에서 멀티미디어 플랫폼으로 중요한 역할을 차지해 왔으나 최근 HTML 5.0의 부상으로 Flash 무용론이 일반인들에게 널리 퍼지게 되었다. 본 논문에서는 Adobe Flash와 HTML 5.0을 비교 분석하여 각각의 장, 단점을 분석해보고, 과연 Flash가 앞으로 쓸모없어질 지에 대한 논의를 해보고자 한다.

With the diversified development of modern art, the application of mixed media in painting has become increasingly prominent, which not only provides artistic creators with new creative ideas, but also magnifies the creators' emotions and re endows the media with meaning and value. This paper systematically introduces the definition, features and connotation of mixed media painting, and expounds three aspects of the aesthetic function of multimedia in oil painting creation, the embodiment of painting individuality, and the combination and application of materials and technique to demonstrate that mixed media presents different understanding and expression in Chinese oil painting, no longer constrained by traditional oil painting materials, which promotes more development possibilities of the art expression form of Chinese oil painting, enhances its international influence, and bring new vitality to the creation and development of Chinese oil painting.

In this work, we present the novel scheduling algorithm of the multimedia data retrieval for the mobile disk drive. Our algorithm is focused on minimizing the power consumption involved in data retrieval from the local disk drive. The prime commodity in mobile devices is the electricity. Strict restriction on power consumption requirement of the mobile device put unique demand in designing of its hardware and software components. State of the art disk based storage subsystem becomes small enough to be embedded in handhold devices. It delivers abundant storage capacity and portability. However, it is never be trivial to integrate small hard disk or optical disk drive in handhold devices due to its excessive power consumption. Our algorithm ARM in this article generates the optimal schedule of retrieving data blocks from the mobile disk drive while guaranteeing continuous playback of multimedia data.

In this paper, we discuss a novel reservation-based, asynchronous MAC protocol called 'Multi-rate Multi-hop MAC Protocol' (MMMP) for multi-hop ad hoc networks that provides QoS guarantees for multimedia traffic. MMMP achieves this by providing service differentiation for multirate real-time traffic (both constant and variable bit rate traffic) and guaranteeing a bounded end-to-end delay for the same while still catering to the throughput requirements of non real time traffic. In addition, it administers bandwidth preservation via a feature called 'Smart Drop' and implements efficient bandwidth usage through a mechanism called 'Release Bandwidth'. Simulation results on the QualNet simulator indicate that MMMP outperforms IEEE 802.11 on all performance metrics and can efficiently handle a large range of traffic intensity. It also outperforms other similar state-of-the-art MAC protocols.

This study aimed to identify visuality changes in the $21^{st}century$ digital visual media art through the expension of digital frames based on visuality represented by Cartesian perspectivalism in the modern age. The visuality of perspective, camera obscura and panorama, which are called modern visual systems, was analyzed to illustrate each characteristic from a viewpoint of a seeing subject. These characteristics of the visual systems were restructured to meet the visuality of the digital era through the illustrations of Lacan's gaze. In addition, the characteristics of frames found in the $21^{st}century$ digital visual media art were identified, and they were categorized into and illustrated from physical, convergent and interactional viewpoints. The outcomes were classified into the $21^{st}century$ digital frame types, and new $21^{st}$century digital visual illustrations were suggested based on the results.

A site-specific performance is a genre and a phenomenon that has recently emerged as a recent paradigm of performing arts: a communality. It involves the performativity of the audience and has various phenomena of contemporary performing art. This study aims to figure out methods of performativity. "Lost Missing and Forgotten," which is a collaboration from Finland and Korea created in 2012 and "Trailer," which is held in Copenhagen Denmark in 2010 by Kitt Johnson. Three principles of performativity which have borrowed as critical tools for this study are role reversal, community building, and contact, which based on "The Aesthetics of Performativity," written by Erika Fischer-Lichte in 2017. The study results show that performativity in the vertical structure and horizontal structure of site-specific performance can act as an environmental factor through the audience's body. Additionally, it turned out that role reversal principle was transformation audience to a creator; community building principle led to an interest in neighbors. Lastly, the contact principle was one of the methods to watch the performance.

After 2011, with the spread of smart devices, large interfaces using the architectural space elements here and there in the cities. Recently the desire for the data has increased, and, following the increase of the range of use by the users, the communication utilizing various forms of interfaces is expected to become more active. In the past, certain range of architecture or parts of the facilities were as the interfaces, but, recently, the development of media technology and the display of various contents forced the utilization of many elements of architectural space in the interface aspects that were not used in the past. Accordingly, the research compare the relationship of the purpose, media environments, interface technology, data form and so on and consider the characteristic of what elements of architectural space are used in order to analyze the characteristic of interfaces used in digital art works. Especially,the research will consider the possibility of commercializing the trends in the interfaces of digital art works in the mediation region of city information services, and propose how to apply such possibility.

Face detection is the first step in a wide range of face applications. However, detecting faces in the wild is still a challenging task due to the wide range of variations in pose, scale, and occlusions. Recently, many deep learning methods have been proposed for face detection. However, further improvements are required in the wild. Another important issue to be considered in the face detection is the computational complexity. Current state-of-the-art deep learning methods require a large number of patches to deal with varying scales and the arbitrary image sizes, which result in an increased computational complexity. To reduce the complexity while achieving better detection accuracy, we propose a fully convolutional network-based face detection that can take arbitrarily-sized input and produce feature maps (heat maps) corresponding to the input image size. To deal with the various face scales, a multi-scale network architecture that utilizes the facial components when learning the feature maps is proposed. On top of it, we design multi-task learning technique to improve detection performance. Extensive experiments have been conducted on the FDDB dataset. The experimental results show that the proposed method outperforms state-of-the-art methods with the accuracy of 82.33% at 517 false alarms, while improving computational efficiency significantly.
