The purpose of this paper is to make sure of identity as a paradigm of new fsahion to introduce the concept of Sumulacres by J. Baudrillard, For converting to new aesthetic value. To do this, we started observing the general concept of Simulacres, and examined Cyberpunk within thinking of Simulacres and Cyberpunk fashion at virtual space, and then divided aesthetic consciousness appeared at Cyberpunk fashion centering on the concept of Simulacres into inwards sense and outwards sense. Cyberpunk is understood to be one of tendency in the cyber cultures controlled by computer and electronic technology. It is not yet defined clearly and therefore ambiguous and still being elaborated. However, the form started changing our sense sinking into overall cultures in the World, including even movie, literature, music and fashion, and giving complex, deep cultural and artistic possibilities. Also, as a subculture, Cyberpunk is building its own cultural territory in cyber space and is experiencing more real Simulacres than that of it in the ordinary life.

음악에서 동기는 독립성을 지니는 최소 단위이며, 저작권 검사의 단위로 이용된다 따라서, 한 음악에서 약간의 변화를 가지고 반복되는 주제선율을 추출하거나, 다른 음악간의 유사도를 측정하는데 유사도 계산은 필요하다. 본 논문에서는 비교되는 동기의 선율정보를 음 길이와 음높이가 함께 고려되는 시계열 데이타로 변환하고, cosine measure를 이용하여 동기간의 유사도를 계산한다. 시계열 데이타에서 유사도 계산으로 사용되는 유클리드 거리함수 대신 cosine measure를 이용한 경우, 공간상의 거리 합대신 변화 방향이 반영됨으로써 비교되는 동기간의 유사도를 정확하게 계산한다. 본 논문에서 제안된 동기간의 유사도 계산은 내용 기반 음악 검색에서 색인으로 사용되는 주제선율을 추출하거나, 다른 음악의 동기간의 유사성을 비교하는데 이용될 수 있다.

In this paper, in the middle of progressing popular music chord, a method of inserting melody is addressed, which utilized by analyzing chord progress pattern. Firstly, a method for transforming melody into bit pattern which is to be used for neural network input is described. In order to insert the melody, composition pattern is learned from back propagation neural network, and based on these data new melody is to be generated. Experimental results verified the possibility of neural network based computer composition.

Although most of the people have studied English for a long time, their English conversation capability is low. When we provide them portable conversational-type English learners by the application of computer and information process technology, such portable learners can be used to enhance their English conversation capability by their conventional conversation exercises. The core technology to develop such learner is the development of a voice recognition and synthesis module under an embedded environment. This paper deals with voice recognition and synthesis, prototype of the learner module using a DSP(Digital Signal Processing) chip for voice processing, voice playback function, flash memory file system, PC download function using USB ports, English conversation text function by the use of SMC(Smart Media Card) flash memory, LCD display function, MP3 music listening function, etc. Application areas of the prototype equipped with such various functions are vast, i.e. portable language learners, amusement devices, kids toy, control by voice, security by the use of voice, etc.

Recently, as the quality of life has been improving, search items in the area of entertainment represent an increasing share of the total usage of Internet portal sites. Information retrieval in the entertainment area is mainly depending on keywords that users are inputting, and the results of information retrieval are the contents that contain those keywords. In this paper, we propose a search method that takes natural language inputs and retrieves the database pertaining to entertainment. The main components of our study are the simple Korean morphological analyzer using case particle information, predicate-oriented token generation, standardized pattern generation coherent to tokens, and automatic generation of the corresponding SQL queries. We also propose an efficient retrieval system that searches the most relevant results from the database in terms of natural language querying, especially in the restricted domain of music, and shows the effectiveness of our system.

본 연구에서는 다차원 추천시스템을 기반으로 동영상 음악추천 시 평가 함수R을 극대화하기 위한 각 다차원 구성요소들은 무엇이고, 이들의 상대적 가중치에 대하여 연구하였다. 일반적으로 추천시스템의 구성변수가 많아질수록 평가 함수R을 극대화하는 것이 유리하나, 계산의 복잡성으로 예측성능과 추천유효성을 저해할 수 있어 구성변수의 증가와 추천 성능을 동시에 해결하는 것이 필요하다. 연구대상 음악동영상은 일반 영상과 달리 오디오 정보와 시선 정보를 싱크하여 감정의 흐름을 추론한다. 실험 대상자는 사용자가 선호할 것으로 예상되는 음악동영상을 추론하기 위하여 대학생으로 한정한다.

Smart machines are one of the topics of our society recently. A smart machine should have a wiser or smarter function than the past. In the modern society, the environment of each family is being improved toward the direction of smart home. In this environment, smart speakers are now increasingly serving as interfaces for controlling various devices in the home, from devices that listen to conventional music. In this paper, we review the technology development trends of domestic and foreign smart speaker market, and describe the core technologies required. In Korea, while SKT and KT are dominant in the speaker market, major IT companies such as Amazon, Google and Apple are focusing on launching related products and technology development.

In the digital world, the transactions of assets with intrinsic value can be applied to games, literature, art, and music by issuing NFTs (Non-Fungible Tokens) based on Blockchain; various NFT exchanges are emerging accordingly just like real world asset exchanges. However, there could be an issue of copyright infringement in those NFT transactions. Therefore, this paper has classified the types of copyright infringement that may occur in NFT exchanges and proposes the copyright infringement countermeasures according to them. For this purpose, 10 types of NFT exchange are examined. Eventually, it can be expected that the proposed countermeasures will contribute to the revitalization of the NFT market by providing solutions for those issues.

Recently many informations are transmitted ,md stored as video data, and they are on the rapid increase because of popularization of high performance computer and internet. In this paper, to retrieve video data, shots are found through analysis of video stream and the method of detection of key frame is studied. Finally users can retrieve the video efficiently. This Paper suggests a new feature that is robust to object movement in a shot and is not sensitive to change of color in boundary detection of shots, and proposes the characterizing value that reflects the characteristic of kind of video (movie, drama, news, music video etc,). The key frames are pulled out from many frames by using the local minima and maxima of differential of the value. After original frame(not de image) are reconstructed for key frame, indexing process is performed through computing parameters. Key frames that arc similar to user's query image arc retrieved through computing parameters. It is proved that the proposed methods are better than conventional method from experiments. The retrieval accuracy rate is so high in experiments.
