본 연구에서는 경기도 설마천 지역에 위치한 독립사면에서 시간에 따라 연속 측정한 토양수분을 이용하여 시계열 분석 을 수행하였다. 토양수분의 측정 방법은 장기간 토양수분의 확보에 신뢰성을 인정받은 TDR을 이용하였다. 관측망의 설계를 통하여 선정한 측정지점에 탐침을 매설하고 공간적인 분포를 가진 시계열 형태의 데이터를 수집하였다. 유출은 해당 사이트 인근에 위치한 사방댐과 전격비교의 수위계에서 실측한 값을 사용 하였다. 전이함수 모형을 사면에서의 토양수분 전이과정에 대응되도록 물리적으로 전개하고 실측한 토양수분 시계열 데이터로 분석한 결과와 비교하였다. 전이 함수 모형은 토양수분 시계열 데이터를 입력변수로 하고 유출 데이터를 반응 변수로 하여 전개하여 토양수분 변화량과 유출간의 전이함수 모형을 도출하였다. 시계열 모형의 전개는 크게 자료전처리, 모형구조의 규명, 모수추정, 모형진단 등의 과정을 통해서 적절한 모형을 도출하였다. 산지 사면에서의 토양수분을 전이함수에 의하여 전개한 모형은 지형적 분포 양상에 따라 특색을 나타내었다. 또한 2003년 가을과 2004년 봄의 전이함수 모형 추정을 통하여 계절별 특성이 나타났고, 모형양상에 원인을 검토해 보았다. 본 연구는 전이함수를 이용한 토양수분의 시계열 분석이 사면에서의 토양수분 변동특성을 지형적, 계절적 특성과 연계하여 이해하고 특성화 하는 과정의 적절한 도구가 될 수 있음을 보여주고 있다.

This paper begins with a critique that researches of geography education in Korea have not reflected the ideological debates in education and geography. The purpose of this paper is to figure implications for socially-critical geography education being studied in England as openly-ideological approach. First, ideological viewpoints of geography education was categorized through analysis of ideology in education and geography. Especially, a limit of conservative and liberal approach is indicated, socially-critical viewpoint is intrinsically justified as alternative logic. Socially-critical theorizing can change teacher's role as an agent of curriculum change and their conduct knowledge as well as geography curriculum. Second, (social) concern-oriented geography education to be more concerned to 'the social' can be realized through the third space approach and committed geography education as critical pedagogy. And, critical literacy is needed to teachers and students for practice of socially-critical geography education.

Neoliberalism can be seen as a path-dependent, hybrid and contradictory project that operates actually (not just ideologically) through intervention of the state that has been not weakened in its strength but different in its strategies, especially through neoliberal policies of remaking urban space. This paper seeks to characterize the development of neoliberalism and urban policies in S. Korea, by examining the trajectory of neoliberalism generated in its contextually specific way since the late 1980s, by illuminating the intersection between new neoliberal programs and the existing developmentalism of the state and changes in spatial policy with its effects, which can be divided into two phases: the first from the late 1980s to the economic crisis in 1997, and the second from the crisis to the present. This paper finally identifies several paths in which the state and the market would be interrelated, and argues that the vision of national development and spatial policy should be welfare(i.e. human)-oriented, not industry(i.e. capital)-oriented.

The purpose of this study is to explore folding as a tool diversifying structures and shapes or forms, and to consider the role and possibilities as structural design sources. First, the morphological characteristics and the elements for transforming pattern of folding are investigated and the way of forming space is also shown. Secondly, the application methods and systems of folding are descrived.

워터프론트의 의미 특히 친수공간과 워터프론트의 차이와 함께 유래와 변천을 살펴보고자 하였다. 아울러 수역적 관점에서 워터프론트 개발사례와 개발의 주요 목적을 구분하였다. 또한 유럽 각국과 미국 등에서의 시기별, 유형별 개발의 주안점과 키워드를 정리하는 한편 개발이 지역경제에 미치는 영향을 정성적으로 다루어보고자 하였다. 마지막으로 관광활성화를 목적으로 하는 경우의 전제조건과 도입사례를 제시하였고, 우리나라 항만친수공간 관련 정책의 전개와 문제점을 제시하였다.

The purpose of this study focuses on the spatial evolution and characteristics of cultural tourism festivals in Chonnam province of Korea. More than 58 community festivals functioned with hallmark events are held annually in the Chonnam province. Most of community festivals were mainly established since 1995, and more than 48 percents of festivals are held in October and May. Spatial diffusion process of festival are divided into three phases: a primary stage before 1995, a diffusion stage from 1995 to 1999, and a condensing stage since 2000 Cultural tourism festivals began at some areas such as Mokpo, Yesu, and Gurye in 1960's, and spread all over the counties of Chonnam province. During diffusion stage, 51.7 percent of all festivals were newly held. The themes and purposes of festival, and the typology of community festivals were transformed with diffusion stage. In festival purpose, community reconciliation and unity festivals were held in primary stage, tourism oriented festivals were held in diffusion and condensing stage. In the festival themes, community culture and folk arts festival were held in primary stage, however, community history and environment & ecological festivals are held in condensing stage. In addition, the typology of community festivals was transformed according to diffusion stage. Thus it was transformed from indigenous festivals of primary stage to commercialized indigenous festivals of condensing stage.

Today's Digital Environment made Typography to enter into a new phase. The Type which is a principal component of Typography is no exception to this aspect. However since the existing two-dimensional space has figurative potential, Visual Communication designers are still striving to explore both X axis and Y axis. In this context, Z axis which signifies 'Depth' is often recognized as an unfamiliar mathematical concept unrelated to Design Sensibility. If Z axis is used, the figurative aspect can be acquired, which was hard to be realized in the flat space, because the additional space of depth allows the expansion of omni-directional expression of target. Most notable is the fact that Z axis provided by Digital Environment has actually long existed and is inseparable from Type. This study, therefore, focuses on the three-dimensional expression of Type in the Visual Communication Design area by taking into account the above characteristics.

We analyzed the technology portfolio matrix for the car navigation technology using QFD method and accordingly suggested the navigation technology development direction. QFD is a useful tool to analyze the customer demands and the technologies. Depending on the survey results from the latent customers and the technology capabilities from the study of the national institutions, we suggested technology portfolio matrix. The visual HMI technology, safe driving support technology, and the navigator information management technology are the most prospective area for R&D investment according to the portfolio matrix.

A space-time finite element method was presented for time dependent problem. The method which treat both the space and time unformly were proposed and numerically tested. The weighted residual process was used to formulate a finite element method in a space-time domain based upon continuous Galerkin method. This method leads to a conditional stabie high-order accurate solver.

영상레이더 (SAR: Synthetic Aperture Radar) 혹은 통신 안테나/탑재체를 장착한 위성은 원하는 주파수 대역의 운용을 위해 대형 안테나 구조물 장착이 필수적이다. 이러한 대형 구조물은 일체형으로 제작되어 위성체에 접속되었을 때, 요구 무게 및 점유하는 부피가 매우 큰 특징을 지닌다. 따라서, 대형 안테나 구조물의 중량으로 인해 발사비 증가가 불가피하며, 페어링 내부의 허용된 공간에 안테나 크기는 큰 제약적 요인이 된다. 그리고, 전개식이어도, 전개후 질량 관성이 큰 구조물이 된다. 위성체의 발사 비용과 직결되는 안테나의 경량화를 위한 많은 기술이 연구되고 있다. 특히, 접이식 팽창형 안테나는 반사체의 유연한 메쉬 구조 및 경량 지지구조물로 안테나의 무게를 줄이고 수납 효율을 향상시킨다. 또한, 전개 후 안테나의 목적한 기능을 충분히 보장함과 동시에 질량 관성이 작은 구조물에 의한 위성의 기동성을 극대화할 수 있다. 국내에서도 전천후 지상관측감시 및 통신 안테나의 필요성 증대에 따라 초경량 전개형 안테나 개발의 필요성이 크게 대두되고 있으나, 현재까지는 관련 기술개발 사례가 전무한 실정으로 국내 독자적 기술 확보가 시급한 실정이다.
