그림과 글의 표현방법에 있어 시각적으로 매우 다르다. 하지만 원천을 거슬러 올라가 보면 같은 뿌리임을 알 수 있다. 그림과 글은 중세의 필사 본이나 인쇄매체의 발견이후 대중들에게 상호보완적인 기능을 다한 후 이미지와 텍스트로 완전 분리하는 시기에 이른다. 이미지가 텍스트로 해석되고 텍스트가 이미지의 도움을 받아 대중과 소통이 활발해지는 상호 교류형태는 문학과 시각예술의 매체화 경향에 따른 학제 간 교류가 활발히 진행되고 있다. 또한 뉴미디어 속에 파고든 시각형상과 문자는 그 용도가 다양하며 하이퍼텍스트의 기능에는 없어서는 안 될 중요한 커뮤니티의 방법이다. 이에 따른 그림과 글의 역사적인 소통체계와 변화과정을 전개하였고 현대적인 신상형문자발생의 근원을 찾아 제안하였다.

리치미디어 서비스는 비디오, 오디오, 텍스트와 같은 다수의 멀티미디어 요소들을 동시에 소비할 수 있으며 시청자의 요구사항을 수용하여 개인화된 데이터에 대한 이용이 가능한 대화형 미디어 서비스를 뜻한다. MPEG(Moving Picture Expert Group)에서는 BIFS(Binary Format for Scenes)와 LASeR(Light Application Scene Representation)를 제정함으로써 리치미디어 서비스를 위한 방안을 제시하였다. 상기 두 표준은 다수의 미디어 콘텐츠간의 시간적, 공간적 배치에 대한 정보와 콘텐츠 간 상호작용을 기술한 장면 구성 정보를 이용함으로써 리치미디어 서비스를 가능하게 하였다. 그러나 기존의 리치미디어 서비스에서는 사용자 및 서비스에 의해서 장면 구성 정보가 변경될 때마다 매번 단말이 가진 기존의 장면 구성 정보를 삭제하고 새로운 장면 구성 정보를 생성 및 분석해야하는 비효율적인 방법으로 장면 전환이 이루어진다. 따라서 본 논문에서는 DOM(Document Object Model) update라는 웹문서 데이터 인터페이스 규격을 사용하여 보다 효율적이고 동적인 장면 구성 변경 방안을 제시하여 장면 전환의 시간적 단축 효과와 장면전환에 따른 화면의 정지 등의 불연속성을 제거하는 효과를 검증하였다.

This media conversion in which webtoons are remediated to movies and dramas has taken off since the mid-2000s. Webtoons may be favorable for media conversion into movies and dramas as the story as finished and has proven to be fun with a fixed readership: however, only a small number of webtoon were successful box office hits or received high viewer ratings. Then in 2017, the movie based on the webtoon, succeed in attracting more more then 10 million viewers. In this regard, this study derived the success factors by comparing and analyzing the narrative structure and visual elements of , which was the biggest hit movie, with the original webtoon. The case analysis showed that there are two necessary elements for success: a text configuration of strategy optimized for media conversion, which is based on understanding the different media characteristics of webtoon and movie; and a configuration strategy that exaggerates the personalities of the characters and compresses the story of a webtoon which features various events and many characters in a long series, in consideration of the characteristics of movie which needs to give a big impact in 2 hours.

Objectives : This paper provides a general introduction of a person Seopa Lee-yidoo and the contents of his medical text, Uigamsanjeonyogyul. The paper then investigates how this text summarized and recomposed Donguibogam. Methods : The paper first reviews the activities and academic leanings of Lee-yidoo, the author of Uigamsanjeonyogyul, as described in his book Seopa-munjip. Furthermore, the paper compares Donguibogam and Uigamsanjeonyogyul's process of summarizing Donguibogam. Based on this the paper divides these comparisons and introduces examples. Results : When the overall composition, formation, and the original contents of Uigamsanjeonyogyul were compared with the texts of Donguibogam, it was discovered that the former wholly accepted the composition of the latter but made bold summarizations. Meanwhile, Uigamsanjeonyogyul added a detailed list of contents at the beginning of the book, and its original contents provided integration, relocation, and detailed explanations of Donguibogam two sections. It gave changes to bogam's prescription configuration and explanations on the mechanism of diseases, and it also added a section for new prescriptions. Like this, Uigamsanjeonyogyul showed a great deal of knowledge regarding the clinical field. Conclusions : Uigamsanjeonyogyul which was published as a summary of Donguibogam, faithfully follows the texts of Donguibogam. At the same time, it provides summary, improvement, and rearrangement based on the author's academic leanings.

In this paper, we propose a novel optical implementation of a 3DES algorithm based on dual XOR logic operations for a cryptographic system. In the schematic architecture, the optical 3DES system consists of dual XOR logic operations, where XOR logic operation is implemented by using a free-space interconnected optical logic gate method. The main point in the proposed 3DES method is to make a higher secure cryptosystem, which is acquired by encrypting an individual private key separately, and this encrypted private key is used to decrypt the plain text from the cipher text. Schematically, the proposed optical configuration of this cryptosystem can be used for the decryption process as well. The major advantage of this optical method is that vast 2-D data can be processed in parallel very quickly regardless of data size. The proposed scheme can be applied to watermark authentication and can also be applied to the OTP encryption if every different private key is created and used for encryption only once. When a security key has data of $512{\times}256$ pixels in size, our proposed method performs 2,048 DES blocks or 1,024 3DES blocks cipher in this paper. Besides, because the key length is equal to $512{\times}256$ bits, $2^{512{\times}256}$ attempts are required to find the correct key. Numerical simulations show the results to be carried out encryption and decryption successfully with the proposed 3DES algorithm.

In this paper, a power flow simulator, which visualizes power flow and system configuration, is proposed and implemented. Generally, it is necessary to prepare a text file with power-system descriptions, which is one of the barriers for power-flow simulations. The proposed simulator has a function of automatic generations of IEEE common data format files from user-drawn power-system diagrams. Therefore, it is possible for users to carry out simulations only by drawing power system on display. In addition, the proposed simulator also has a function that power-system diagram is illustrated automatically from an IEEE common data format file. By using this function, it is possible to visualize amounts and directions of power flows on the bus-system diagram, which helps users to comprehend network dynamics intuitively. Because the proposed simulator allows including renewable-resource generators in power systems, it is useful to evaluate the power distribution system. It is shown in this paper that the proposed simulator can make IEEE common data format files correctly and illustrate intuitive power flow.

The counter-fire operation system performs its mission exchanging information with other related systems such as command & control systems and military information systems. In the process of exchanging information, the counter-fire operation system uses a type of data message which contains exchange data information in the format of KMTF. The requirement of data exchange of count-fire operation will continue to evolve. But the EDX(External Data eXchange) configuration item of the current counter-fire operation system can not effectively cope with the variation of data exchange requirements due to its fixed software structure. In the paper, a solution for improving flexibility of external data exchange in counter-fire operation system is proposed.

The moyamoya disease is a type of cerebrovascular disease which produces thin abnormal blood vessels like haze in the brain base because the end of internal carotid artery which supplies about 80% of blood is blocked. Regarding this moyamoya disease, the shearing stress and thrombus generation are mentioned as its main causes. This study three-dimensionally implemented the ICA, ACA, and MCA parts of the cerebrovascular configuration related to the moyamoya disease, and analyzed the hydrodynamic phenomenon with the commercial program ADINA. In particular, the correlations between shearing stress and speed distribution according to the branch angle of ACA and MCA. A numerical analysis found that the greater the branch angle of ACA and MCA, the lower the shearing stress and the greater the stationary area of the flow.. Put Abstract text here.
