In this paper, we present a carrier phase estimation algorithm for LDPC coded systems. LDPC coded system can not achieve the ideal performance if phase offset is introduced by channel. However, the estimation of phase offset is very hard since the operating point of LDPC is very low SNR. To solve this problem, the algorithm using the tentative soft decision value and based on Maximum Likelihood (ML), was proposed in [2]. But this algorithm has problem which works only under constant phase offset. If phase offset is time variant, it has a severe degradation in performance. To solve this problem. we propose two types of estimators. symbol by symbol estimator: Unidirectional estimator (UDE) and hi-directional estimator (BDE), and sub-block estimator (SBE).

In this study, the pattern of texture was developed by applying the pattern shown in the Amita Yeoraebul and the Avalokitesvara with symbolism suitable for children's clothing. In addition, the design and the manufacturing of a children's wearable Hanbok were attempted, and the results are as follows: Amitha Yeoraebul is a Buddha who oversees paradise in Buddhism, and Avalokitesvara controls both paradise and the real world and provides mercy. Applying the various patterns in the Buddhist paintings, four daily hanboks for children were produced using patterns featuring symbolic the meanings of large round original patterns chrysanthemums, turtles, and lotus patterns. The lotus symbol represents love, nobility, and wealth, while the turtle symbol represents longevity, the chrysanthemum pattern symbolizes auspiciousness, and the large round original pattern means a constant continuation. To maintain the traditional hanbok form but allow convenient wear it in daily life, it is made in the jeogori + shorts, vest + long pants, and one-piece + jacket style. Currently, the daily dress of Hanbok and the modernization of traditional Korean clothes are being promoted. At this point, the study developed Hanbok fashion products that contain symbolic stories suitable for children are trying to maintain the image of traditional culture as much as possible.

In 21st century, subordinated relationship of fashion from the body has been disappearing, and fashion is understood as variable and creative field. This research aims at analysis about the relationship between the body and fashion depending on the theories about the authority and the desire. So, this utilizes between theoretical study and empirical analysis. For concentrated study, research period limits from 2000 to the present time 2010. Contemporary body and fashion have being changed into various forms and values, become complex and de-territory. Especially, body is symbol of ambivalence eroticism that gives point to sexual property, and the object of fetishism and machine having a desire. This study's purpose draw a parallel with between the limits of contemporary body that couldn't be rid of the capital and desire, and the liberty of fashion that escape from the body's influence has being changed independent and fluid space. This research's results are as follow as; contemporary de-territory fashion is expressed as 1) symbol of the object and physical material property, 2) self-transcendental instrument fashion, 3) independent spatial molding, 4) de-centering fashion.

Generally school algebra is to start with introducing variables and algebraic expressions, which have major cognitive obstacles to students in the transfer from arithmetic to algebra. But the recent studies in the teaching school algebra argue the algebraic thinking from an early algebraic point of view. We compare the Korean elementary mathematics textbooks with Americans from this perspective. First, we discuss the history of school algebra in the school curriculum. And Second, we investigate the recent studies in relation to early algebra. We clarify the goals of this study(the importance of early algebra in the elementary school) through these discussions. Next we examine closely the number sense in the arithmetic and the symbol sense in the algebra. And we conclude that the operation sense can connect these senses within early algebra using the algebraic thinking. Finally, we compare the elementary mathematics books between Korean and American according to the components of the operation sense. In this comparative study, we identify a possibility of teaching algebraic thinking in the elementary mathematics and early algebra can be introduced to the elementary mathematics textbooks from aspects of the operation sense.

Beijing, the capital city of China, has gradually increased its amount of culture space and has also introduced a diverse range of cultural facilities to improve the satisfaction of its citizens lives. In particular are its art museums, which are a symbol of the urban culture and enrich the cultural life of its citizens and are also expected to play a role as a psychological pivot point. However, in comparison with the characteristics of various ethics, local, and the influence on the museums of China, studies which analyze the exterior of the art museums are not sufficient. This is because previous research has focused too heavily on the interior of the art museums. This paper aims to derive distinction through the analysis of the exterior of several art museums and present design factors and application methodology. This research looks at art museums in China and analyzes the current state of the art museums that have been developed based on the culture of Beijing. Through analyzing the case study of five art museums that have been selected in Beijing we can improve our understanding of Chinese culture space and derive distinct design factors. Distinct factors in the exterior of art museums include connection, culture, geographic features, public, and creation. This study is expected to contribute to that exterior of the art museum will be as a contact zone to form a spatial connection and a cultural symbol that can reflect Beijing's unique culture characteristics.

The purpose of this study is to design neckties that are motivated by Christmas symbol images that have been known to public most widely in the basis of Day marketing so as to develop the competitive commodities closed to consumers' emotion in the fashion industry. As a method of this study were to use Adobe Illustrator CS2, which is one of the vector graphic programs, to present the motif design such as Santa Claus, trees, presents and letters among Christmas symbols, and are to apply to neckties by giving a change with striped pattern, all over pattern and one point pattern. The results are as follows; Firstly, Santa Claus image was expressed by color contrast with red and white, which was perceived by red, green and white that are mostly used in Christmas. Secondly, tree images are expressed abstractly with color contrast where red and green are contrasted, and color way change was given for symbol color of Christmas. Third, in the image of gift, the image of share and image of colorfulness were considered for expression by making motifs of three dimensional hexahedron shape. Fourthly, in the image of type, motif was expressed by giving a change in horizontal and vertical writing types.

Nowadays, the condition of overcrowded cities has raised a question which is insufficient land in cities, and has gotten worse because of the influx of the population continuously. It has rapidly constructed a skyscraper increasingly that the solution to secure a living space against these overcrowded cities until 2000, but these are already positioning itself as one of the new type of residence. The necessity of skyscraper as facilities of residence inside cities has be available both a solution for overcrowded cities and a meaning for a symbol of its represented a landmark. However, constructing skyscrapers indiscreetly can not guarantee dweller's life environment, and it contains risks unless design and facilities criteria are provided. Now, a skyscraper as a new substitute constituting a living space in the future for overcrowded cities deals with a systematic correlation between a city and construction. Therefore the aim of this study were to indicate a method for improvement of dweller's life environment at skyscraper through establishing a point of reference to inculcate them for a sustainable skyscraper from now on.

펀(Pun)은 언어사용에 있어서 수사학적 효과를 얻기 위해 사용되던 개념인데 비주얼 커뮤니케이션을 위한 디자인에서도 그 개념이 적용될 수 있다. 언어표현에서의 단어가 상징적 이미지로 대치되어 비주얼 펀(Visual Pun)의 형식으로 커뮤니케이션 디자인을 위한 방법이 될 수 있는 것이다. 비주얼 펀의 표현은 고대의 그림문자에서부터 현대의 회화 디자인 등의 시각 언어를 다루는 모든 분야에서 적용되었다. 시각 커뮤니케이션을 위한 비주얼 펀의 표현 방법은 크게 세 가지로 구분할 수 있다 먼저 상징적 이미지를 통해 두 가지 이상의 의미발생을 하고 그 전체적 의미전달은 직접적으로 표현되는 직설적 펀과, 하나의 상징적 이미지나, 또는 두 개의 상징적 이미지의 결합을 통해 다양한 의미의 발생이 이루어지면서 전체적인 의미를 암시적으로 표현하고 강화하는 것의 연상적 펀이 있다. 그리고 유사한 두 가지의 상징적 이미지를 서로 비교하거나, 유사한 이미지들의 병치를 통해 전체적 의미를 강화하는 비교적 펀으로 정의될 수 있다. 전통적 시각 커뮤니케이션을 위한 문법으로 활용되었던 비주얼 펀의 개념은 다양하고 새롭게 나타나는 매체에서의 시각표현에서도 여전히 유효한 방법이 될 수 있다. 따라서 웹사이트에 나타나는 상징적 이미지의 사용에도 비주얼 펀의 개념이 적용되는 것은 자연스럽다. 웹사이트에서 이미지의 구성형식은 전체 사이트의 차별성을 드러내는 가장 중요한 요소 중의 하나이다. 그러나 현재의 웹사이트는 사용성과 같은 기능 위주의 디자인에 중점을 두다보니 그 형식이 점차 획일화되고 있으며, 이는 일정한 틀이 형성되어 디자이너들이 무의식적으로 따라가는 경향을 보이고 있다. 이런 상황에서 웹 디자인을 위해 비주얼 펀의 개념 적용에 대한 새로운 인식은 웹사이트에서의 상징성을 강화하여 정보전달의 의미를 강화할 수 있는 디자인방법이 될 수 있다. 그로 인해 다른 사이트와 구별되는 차별적 아이덴티티를 확보할 수 있고 보다 효율적인 커뮤니케이션이 이루어지게 하는 디자인 문제 해결을 위한 대안이 될 수 있는 것이다.
