The purpose of this study is to find the way to build the concept image about natural logarithm and the method is using definite integral in calculus under GeoGebra environment. When the students approach to natural logarithm, need to use dynamic program about the definite integral in calculus. Visible reasoning process through using dynamic program(GeoGebra) is the most important part that make the concept image to students. Also, for understand mathematical concept to students, using GeoGebra environment in dynamic program is not only useful but helpful method of teaching and studying. In this article, about graph of natural logarithm using the definite integral, to explore process of understand and to find special feature under GeoGebra environment. And it was obtained from a survey of undergraduate students of mathmatics. Also, relate to this process, examine an aspect of students, how understand about connection between natural logarithm and the definite integral, definition of natural logarithm and mathematical link of e. As a result, we found that undergraduate students of mathmatics can understand clearly more about the graph of natural logarithm using the definite integral when using GeoGebra environment. Futhermore, in process of handling the dynamic program that provide opportunity that to observe and analysis about process for problem solving and real concept of mathematics.

The purpose of this study is to demonstrate that the main creative attitude in Lee Eun-sang's Sijo relies upon the juxtaposition technique, with paying attention to juxtaposition of being found in the works of being put in the Nosan Sijojip(時調集, collection of Sijo poems), and that this creative attitude provides readers with the easiness for understanding. A type in the juxtaposition technique, which was shown in "Nosan Sijojip", was divided in the dimension of the anaphora in a meaning and the confrontation in a meaning. The anaphora of a meaning was classified into synonymous juxtaposition, comprehensive juxtaposition, specific juxtaposition and syntactic juxtaposition. The confrontation of a meaning was examined in the contradictory juxtaposition. Most of Lee Eun-sang's works are applying this juxtaposition technique. Also, the dynamic of image, which is indicated in juxtaposition, is what was influenced by the British and American imagism. This study will be able to solve problems that modern Sijo has to some extent, and will be helpful even for acquiring the identity in Sijo.

This study conducted a comparative analysis between Koreans and foreigners on how they feel of the 'Oreum' so that the data could be used to conserve and utilize 'Oreum' as a brand of Jeju, which is one of the natural and original sceneries of the island along with Halla Mountain. Four aerial photo slides were selected to be assessed among 18 overlooked views of 'Oreums' through quasi-preliminary and preliminary surveys. The assessment group was divided into native and foreigner groups. Image and preference were measured based on 7 step categorization on 26 adjectives, and factor analysis was implemented. The selected factors from factor analysis reflected that calmness was recognized as common image identification variable to natives and foreigners. However, foreigners choose 'dynamics', 'peculiarity' and 'grandeur' in order to explain the image while Koreans selected words in the order of 'attractiveness', 'grandeur', 'dynamics' and 'peculiarity'. This means Koreans identify the image of 'Oreum' as absolute beauty while foreigners see the dynamics and relative peculiarity as its attractive point. As a result of factor score, preference and multiple regression analysis, Koreans selected 'calmness', 'attractiveness' and 'dynamics' as important variables to explain preference. On the other hand, foreigners choose 'dynamics' and 'calmness' as well as 'evenness', 'peculiarity' and 'simplicity'. This represents that foreigners are highly influenced by the structural peculiarity and simplicity on the image preference.

본 연구는 낭만주의 화가 프란시스코 고야의 작품 <아들을 먹어치우는 사투르누스>의 영감을 토대로 춤연극 를 제작하였다. 따라서 제작과정에 나타난 움직임의 상징적 의미와 언어적 소통의 다섯 가지 분석을 시도하였다. 연구결과 첫째, 표현주의를 대표하는 고야의 작품 <아들을 먹어치우는 사투르누스>에 나타난 공포와 괴기 속에 드러난 소통과 상징성은 움직임의 표현적 이미지에 하나의 'signal'적(的) 소통으로 직결되었다. 둘째, 프란시스코 고야가 나타낸 인간의 잔인성, 참혹함이 춤연극 제작을 통해 다른 의미로의 해석이 가능했다. 이것은 움직임 상징성과 역동적 에너지가 갖는 의미와 해석의 다양성으로 인식된다. 셋째, 정적이미지의 그림요소와 색채가 갖는 상징성은 춤연극의 언어적 유희와 움직임의 다섯 가지 상징적 이미지 체계로 정리되었다.

For a long time, we have been good at the static image, 'the country of calm morning' as reminding Korea. But, it became a chance that we were recognized newly and actively through the success of the Olympic games in 1988 and World cup games in 2002 all over the world. And foreigners' interest and expectation for Korea becomes much higher by these reasons. Moreover, the importance of our cultural industry, recognition for new cultural improvement have been changing step by step by the oriental trend in Asia in these days. So, this study intends to realize the Korean symbol with showing Korean Identity and its image's applying to the street furniture design through the making of special street which expresses well the Korean Image. There is a purpose of this study not to use as just street furniture but to make characterized Korean culture through showing examples which are based on Korean culture. The way of the improvement for the street furniture design using Korean image are these we analyze the character of Korean international image with the previous data for the change of Korean Image. We understand the symbol of changed Korean international Image, and extract the design elements. We analogize the shape, material and color image of the street furniture which is joined with both the Korean national image and formative traditional elements. At last, we formalize its symbolic image by applying to the street furniture according to the design improvement process with the analogized image. The formal study using Korean image makes more cleary the Korean Identity, and it doesn't influence only the actual change but also Korean cultural value equipment.

This research studied the role of images between visual thinking and analytic thinking to contribute to the ongoing discussion of visual thinking and analytic thinking and images in mathematics education. In this study, we investigated the thinking processes of mathematically gifted students who solved tasks generalizing patterns and we analyzed how images affected problem solving. We found that the students constructed concrete images of each cases and dynamic images and pattern images from transforming the concrete images. In addition, we investigated how images were constructed and transformed and what were the roles of images between visual thinking and analytic thinking. The results showed that images were constructed, transformed, and sophisticated through interaction of visual thinking and analytic thinking. And we could identify that images played central roles in moving from visual thinking to analytic thinking and from analytic thinking to visual thinking.

The purpose of this study is to investigate the antecedents of city brand personality and those effects on city brand personality and attitude toward city. This study attempts to confirm dimensions of city characteristics and city brand personality, and analyze the structural relationships among the city characteristics, city brand personality and attitude toward city. The result showed that various characteristics of city (culture and historic characteristics, life stability, facility convenience, economic factors, the image of city appearance, nature friendly characteristics) influence city brand personalities. In addition, city brand personalities (vivid personality and stable personality) are positively related to attitude toward city and mediated between the characteristics of city and attitude toward city.

'Smart Grid 선도 기업', '국내 최고의 전력 자동화 기업' 등이 최근 LS산전을 인식하는 대표적인 상징어로 각인되고 있다. 이 가운데 스마트 그리드 분야의 선도 이미지는 LS산전이 지난 10여 년간 투자해온 전력IT 분야의 결실로 평가되고 있다. 1974년 설립된 LS산전(대표 구자균)은 과거의 생존게임을 탈피, 대단위 투자를 통한 그린 비지니스 전략 및 비전을 구체화 하고 있다. 국가적 차원의 아젠더로 추진되면서 일상생활의 패러다임을 변화시킬 원천기술인 스마트 그리드와 HVDC, 전력선 통신, 연료전지 등의 상용화 기술개발에도 박차를 가하고 있다. 품질경영과 혁신활동을 중시하면서도 창조적이고 역동적인 소통의 기업문화를 자랑하는 LS산전의 미래성장을 위한 글로벌 열정은 여전히 진행 중이다.
