최근 이동 무선망을 통한 발전된 비디오 응용 서비스에서 비디오 스트림의 크기를 효과적으로 줄이는 트랜스코더가 필요로 하게 되었다. 이러한 트랜스코더는 화소공간뿐만 아니라 DCT 공간상에서도 가능하다. 본 논문에서는 화소공간과 DCT 공간을 활용하여 시각적 화질을 유지하면서 영상 크기를 효과적으로 줄이는 새로운 고속 복합 트랜스코더를 제안하였다. 또한 부호화 모드 결정과 움직임 벡터 재산출 방법을 제안하였다. 대표적인 실험용 비디오 시퀀스에 적용하였을 때 기존의 공간영역 트랜스코딩 방법과 유사한 시각적 화질을 유지하면서도 계산량을 감소시킬 수 있었다. Recently, many advanced video application services over the mobile wireless networks have required a transcoder which can efficiently reduce the size of compressed video bitstreams. The transcoder can be worked in either the spatial domain or the DCT domain. In this paper, we propose a new fast hybrid-type transcoder which can efficiently reduce the frame size with keeping the visual quality. The proposed scheme consists of two major processes: a transform domain process and a spatial domain process. We also propose a scheme for coding mode selection and motion vector refinement. Experimental results show that our approach can reduce the computational complexity more than any other conventional spatial-domain transcoder with keeping the visual quality.

본 연구는 우리나라 교양기초교육의 어려운 상황을 타개하기 위한 근본적 처방을 교육기호학(Edusemiotic)의 관점에서 모색하고자 한다. 최근 대두되는 교육기호학은 기호학 특유의 총체적 접근을 통해 기존의 교육사상과 철학이 견지해 온 관점과 영역을 넘어서는 인식론적 대안을 제시하였다. 한 편, 4차 산업혁명의 도래는 교육, 특히 고등교육의 혁신을 요구한다. 본 연구는 교육기호학의 태동 과정에서 대두되는 새로운 교육철학과, 4차 산업혁명이 요구하는 새로운 교육이념 및 교육과정이 상호 부합된다는 점을 주목하고, 시대적 상황에서 필연적으로 대두되는 고등교육의 혁신을 제안 하고자 한다. 이를 위해 본 연구는 먼저 교육기호학이 이루어 낸 기존 성과들을 비판적으로 수용하고자 한다. 두 번째로 국내 교양기초교육의 문제를 교육 이념, 교육과정, 교육편제 별로 살펴 핵심 문제를 도출한 후 이를 교육기호학의 관점에서 진단하고 해결책을 모색하고자 한다. 본 연구는 마지막으로 교육기호학의 교육이념을 구현할 수 있는 고등교육제도로 신인문학(Neo-Humanities) 중심의 교육과정을 채택하는 한국형자유학예대학(Neo-Liberal Arts College)의 건학을 제안하고 이를 설계하고자 한다. The purpose of this study is to explore the fundamental prescription to overcome the difficult situation of higher education in Korea from the point of view of Edusemiotics. Recently, edusemiotics has suggested epistemological alternatives beyond traditional philosophical perspectives through the holistic approach that is peculiar to semiotics. On the other hand, the advent of the 4th Industrial Revolution calls for innovation in education, especially in higher education. This study focuses on the fact that a new educational philosophy is emerging in the process of edusemiotics, that the new education ideology and the curriculum required by the 4th Industrial Revolution are mutually compatible, and suggests the innovation of higher education inevitably requested. The purpose of this study is to critically accept the existing achievements of edusemiotics. Secondly, the problems of basic education in Korea are examined by an innovative education ideology, and the present curriculum, and education system are critically reinterpreted. Finally, this study proposes and suggests the establishment of a Korean-style liberal arts college(Neo-Liberal Arts College) that adopts a curriculum centered on Neo-Humanities as a higher education system that implements educational philosophy of edusemiotics and heutagogy, self-determined learning.

This paper aims at describing roughly the trend and issues of Chinese contemporary art from 80’ to today. The chronological marks of Chinese modern art are defined with the political upheaval of the modern Chinese history, i.e., The ‘Cultural Revolution’, ‘Tiananmen’, and followed ‘Reform and Opening’ of China. Consequently, global comprehension of Chinese contemporary art has been attracted by the so-called “si da tianwang” and their art works known as Chinese avant-garde. This paper has examined the misunderstanding of the precedent about Chinese contemporary art, and revealed that up-to-dated contemporary Chines artists have overcome the political scratches of the past. Ignoring the Western view point of evaluation, some of them try to reinterpret the everlasting tradition of Chinese art, like Ink Painting, and their achievements proved to be the unique art form. Meanwhile, with the rapid economic growth of the region, the contemporary Chinese art and artists are deeply undermined by the commercialization of fine arts, and the paper does not forget to criticize it.

J.-M. Floch, un des disciples de Greimas, a public trois livres intervales gaux. Petites mythologies de 1`oeil et de 1`esprit(1985) vise construire la smiotique plastique. Celle-ci a pour but de comprendre les conditions de production mais aussi lintentionalit dun certain type de relation entre un signifiant visuel et un signifi. Tel propos implique le refus de substituer aux objets de sens manifests par le jeu des eslments figuratives une lexicalsation immediate de leur seule dimension figurative. Ce propos se transforme dans SEmiotique, marketing et communication (1990) . L`auteur pense que la smiotique peut representer, dans le domaine de marketing, une relle valeur aioute dans trois types de production ou de transformation : il faut obtenir plus dintelligibilit. plus de pertinence, plus de diffrenciation. Dans Identity visuelles(1995). 1`auteur a conscience de revenir son cap. Sengager dans 1`analyse des identitess visuelles, cest continuer travailler sur les rapports entre le sensible et lintelligence : au centre des analyses se situe le concept de `bricolaBe`. Nous critiquons que cette mrstamorphose est dGe des caractcres flous de la thorie du plastique mane mais nous estimons que le trajet intellectuel de Floch s`arrte la naissance de la smiotique syncrtique, qui abordera les divers discours sur la culture de 1`image.

This article describes a simple method for generating the walking trajectory for the biped humanoid robot. The method used a simple inverted model instead of complex multi-mass model and a reasonable explanation for the model simplification is included. The problem of gait trajectory generation is to find the solution from the desired ZMP trajectory to CoG trajectory. This article presents the analytic solution for the bipedal gait generation on the bases of ZMP trajectory. The presented ZMP trajectory has Fourier series form, which has finite or infinite summation of sine and cosine functions, and ZMP trajectory can be designed by calculating the coefficients. From the designed ZMP trajectory, this article focuses on how to find the CoG trajectory with analytical way from the simplified inverted pendulum model. Time segmentation based approach is adopted for generating the trajectories. The coefficients of the function should be designed to be continuous between the segments, and the solution is found by calculating the coefficients with this connectivity conditions. This article also has the proof and the condition of solution existence.

La premiere tdche de la smiotique visuelle sera de dgager les units hirarchises de `nonc visuel, et plusieurs mod8les ont t dvelops au cours de ces vingt dernires annes. Ici nous faison une rwision du `modle global du dcodage visuel$quot; et des processus perceptif et cognitif proposes par Groupe p. Nous le trouvons bien distingu des autres approches: celui-1 est construit dans le cadre de la $quot;microsjotique$quot;, qui se condamne rester au niveau de grandes gnralitks pistmologiques. Le modle(tableau I) comprend les stapes successives par. lesquelles on parse des entitles perceptibles visuellement et de ce qu`on nomme $quot;repertoire$quot;, au sens global intg confr 1`objet. Les diffrents produits se rpartissent en trois niveaux. Le premier nivesu est celui des donnes de base: le niveau 2 est celui des processus perceptifs: le niveau 3 est celui des processus cognitifs. Le repertoire, comme systme de differences, est organist. I1 est dfini comme un systme de types. Toutes les figures perues sont soumises une preuve de conformity: elles sont confrontea des types. Pour envisages les phnom8nes visuels comme producteurs de signer, Groupe u reformule le shma d`un mod8le hi~rarchique de 1`information perceptuelle de Palmer(tableau II). En conclusion, les auteurs distinguent cinqtypes de determinations. Une unity visuelle est reconnaissable par ses caractres globaux, par ses relations positionnelles avec 1`unit qui 1`englobe, par ses relations avec les unitks en lesquelles elle se decompose, et par les units qui lont procde dans le temps et/ou dans la mime portion d`espace.
