  • This study was conducted to confirm the necessity of analogical thinking and to empirically verify the effectiveness of analogical reasoning through the visual representation by analyzing the factors of problem solving depending on analogical conditions. Four conditions (a visual representation mapping condition, a conceptual mapping condition, a retrieval hint condition and no hint condition) were set up for the above purpose and 80 twelfth-grade students from C high-School in Cheong-Ju, Chung-Buk participated in the present study as subjects. They solved the same mathematical problem about sequence of complex numbers in their differed process requirements for analogical transfer. The problem solving rates for each condition were analyzed by Chi-square analysis using SPSS 12.0 program. The results of this study indicate that retrieval of base knowledge is restricted when participants do not use analogy intentionally in problem solving and the mapping of the base and target concepts through the visual representation would be closely related to successful analogical transfer. As the results of this study offer, analogical thinking is necessary while solving mathematical problems and it supports empirically the conclusion that recognition of the relational similarity between base and target concepts by the aid of visual representation is closely associated with successful problem solving.

  • Personal creativity could be promoted and improved through many experience, training and various prior knowledge. This researcher had proceeded several preceding studies to find effective using methods of analogy for creativity enhancement. This study, following work of preceding studies aims to verify the effects of verbal and visual analogy for creativity improvement. Effect verification had been progressed by comparing the residential design results of two groups which are classified an experimental group consisted of sophomore college students with a comparative group consisted of sophomore university students. Consequently, the experimental group that had undergone many training on verbal and visual analogy in several preceding studies is superior to the comparative group in terms of creative design rate, sketch rate with high quality. Through this result it is verified that the using methods of verbal and visual analogy is very effective on creativity enhancement in interior design process. But the limitation of this study is that there were a few populations. Nevertheless, interdisciplinary this study will be used as a practical one to suggest a model on a teaching method and a theory for creativity improvement in interior design education.

  • It is well-known that the scenic visibility achieved in our naked eyes is related with the quality of aerosol condition which is composed of primary and secondary air pollutants. In recent, the IMPROVE organization in U.S.A. has developed two algorithms to estimate the visible length depending on the elements of air pollutant. Using these algorithms, we are to represent the condition of aerosol quality with the well-known scenic images of the observing area so that any one that have no sufficient chemical knowledge may feel and understand the level of air pollution in visuality.

  • The objective of this study is to find a educational method that is able to increase creativity using both left and right directed thinking with complementary cooperation. The premise of experimental study is that analogical inference is a great help to make a creative design, and design tasks of commercial space, fashion shop and herb cafe are given to 25 students, voluntary participants in experimental tests. Tests make a clear distinction between a case using verbal analogy from many keywords and another case using verbal visual analogy from keywords and visual images. Consequently, when students use both verbal and visual analogy in solving design tasks their creative ability qualitatively as well as quantitatively is higher than in using verbal analogy. However, when students are classified with high and low sketching group verbal visual analogy is effective for students with high sketching ability to enhance both practicality and originality. Even students with low sketching ability can improve originality remarkably by using verbal visual analogy. In experiment there is time limit, a hour, but in actual studio class it is desirable that an educator guides the latter to make up for the weak points in practicality of their design taking time. Further study will be progressed with the design tasks of residential space to compare with the findings of this study.

  • The objective of this study is to find an educational method that is able to increase creativity using both left and right directed thinking with complementary cooperation. The premise of experimental study is that analogical inference is a great help to produce a creative design, and the design tasks of residential space are given to 20 students, voluntary participants in four experimental tests. The first test is conducted with fundamental conditions such as site or location, users and their design requirements. Other three tests make a clear distinction with three cases using verbal analogy from many keywords, using visual analogy from many images and using verbal visual analogy from keywords and visual images. Consequently, when students use both verbal and visual analogy in solving design tasks their creative ability qualitatively as well as quantitatively is higher than in using only verbal analogy or visual analogy. Further study will be progressed with the design tasks of residential space in order to have an effective verification by comparing students' design results classified into two groups. One is a control group that consists of sophomore students in a college and another is a comparison group that consists of sophomore students in an university.

  • Analogical thinking is a problem-solving strategy to use a familiar problem (or base analog) to solve a novel problem of the same type (the target problem). The purpose of this study is to provide new insight into geography teaching and learning by connecting cognitive science research on analogical thinking with issues of geography education and suggest that teaching with analogies can be a productive instructional strategy for geography. In this study, using the various examples of analogical thinking used in geography we defined analogical thinking, addressed the theoretical models on analogical transfer, and discussed conditions that make an effective analogical transfer. The major research findings include the following: a) the spatial analogy, indicating skills to find places that may be far apart but have similar locations, and therefore have other similar conditions and/or connections, can provide a useful way to design contents for place learning; b) representational transfer, specifying a common representation for two problems, can play a key role in solving geographic problems requiring data visualization and spatialization processes; and c) either asking learners to compare/analyze similar examples sharing common structure or providing them examples bridging the gap between concrete, real-life phenomena and the ideas and models can contribute to learning in geographic concepts and skills. The spatial analogy requiring both geographic content knowledge and visual/spatial thinking has the potential to become a content-specific problem-solving strategy. We ended with recommendations for future research on analogy that is important in geography education.

  • 인간은 소리를 통해 많은 정보를 얻을 수 있다. 누가 어떤 말을 하는지 뿐만 아니라, 상황에 따라서는 소리가 발화된 환경 또한 시각적인 정보 없이 유추할 수 있다. 이러한 판단을 내리기까지, 인간은 경험을 통해 스스로 학습하는 과정을 거친다. 이와 같은 학습 과정에 생물의 사고과정을 모방하여 복잡한 상관관계를 추론하는 인공지능형 알고리즘을 적용하면, 인간의 두뇌가 경험을 통해 학습하고 판단하던 역할을 기계적으로도 모방할 수 있게 된다. 본고에서는 음향이 발화된 환경의 정보를 나타낼 수 있는 파라미터들에 대해 알아보고, 그 파라미터들을 지능형 알고리즘을 이용해 도출해내는 과정과 기법들을 소개한다.

  • 자연을 분석함으로써, 얻어진 기하학적 패턴은 이미 자연의 질서를 포함하고 있는 논리적이고 합리적인 기본형이기 때문에 간결하며 시각적으로 명쾌감을 준다. 이러한 기하학적 패턴은 복식 디자인에 있어서 20 세기 이후 여러 디자이너의 작품을 통해 재구성되어 현대적 이미지를 나타내는 중요한 모티브가 되고 있으며, 다양한 기법과 재료로 형성화하여 도입되고 있다. 이에 본 연구는 복식의 문양, 실루엣, 디테일에 사용되고 있는 기하학적 패턴을 연구함으로써 기하학적 패턴의 새로운 조형가치를 고찰하였다. 먼저 기하학의 용어 정의를 하였고 기하학적 패턴의 유형과 표현 기법을 분석하고 정리하여 현대 패션에 나타난 기하학적 패턴의 조형미와 그것을 바탕으로 패션 이미지를 추론해 보았다. 현대 패션에 나타난 기하학 패턴을 분석해 보면 유형으로는 첫째, 기하하적 문양으로 복식디자인에 있어서 주로 평면적인 형태로 많이 나타나지만, 크기가 다르고 동일한 기하학적 패턴을 조합시킴으로서 평면적인 형태에 공간감을 부여하기도 하며, 같은 기하학적 패턴의 표면이라도 배치구조에 의해 직선 혹은 사선으로 지각되므로 전혀 다른 이미지를 주었다. 또한 현대 패션에 나타난 기하학적 패턴이 종류는 세로 스트라이프, 가로 스트라이프, 격자 문양, 원, 사선 스트라이프, 마름모, 사각형, 삼각형 등의 순서로 많이 나타났다. 둘째, 색채는 단색의 복식에 강한 대비가 이루어지는 색상으로 표현되어 역동감과 유연한 운동감을 나타났다. 셋째, 기하학적 실루엣으로 단순한 라인의 형태를 나타내거나 입체적이고 부조적인 형태로 구성되어 전체적인 실루엣으로 사용되어 강한 조형감각을 보여주는데 원형을 이용한 실루엣이 가장 많았으며 사각형을 이용한 실루엣, 삼각형을 이용한 실루엣 순서로 나타났다. 넷째, 기하학적인 디테일로 복식의 어느 한 부분에 장식적으로 사용되거나 입체적 형태로 부출 되어 부조적인 느낌을 주는데 소매에 가장 많이 나타났으며 앞여밈, 칼라, 밑단, 주머니 순서로 장식되었다. 다섯째, 현대 패션에 표현된 기하학적 패턴의 표현기법으로는 프린팅, 퀼팅, piece기법, 패치워크, 엮기, 꼴라쥬, 아플리케 순서로 많이 나타났다. 위의 분석을 토대로 기하학 패턴을 활용한 디자인에 내재된 조형의지는 다음과 같이 정리되었다. 첫째, 기하학적 패턴이 지닌 단순성과 경직성을 완화하기 위하여 여러 가지 패브릭을 조합시켜 입체적인 표면효과로 시각적인 착시효과를 극대화하였다. 둘째, 표현기법은 입체파적 표현주의의 특성의 하나로 복시에 사용되는 소재의 왜곡으로 설명할 수 있으며, 새롭고 실험적인 소재의 도입으로 인해 의외성과 부조화를 유발시키는 통시에 유희직인 일면도 지니는 일종의 그로테스크를 나타냈다. 이상에서 정립된 조형의지를 바탕으로 현대 패션에 나타란 기하학 패턴은 절제된 단순함과 명확성으로 단순미가 유추되었고 강한 색상대비로 인한 시각적 집중효과로 주목성을 가지며 재현이 가능하므로 반복성이 유추되었다. 그리고 표준영역이 없는 창의적 표현으로 풍부한 독창성을 보여주고 있다. 또한 내재된 패션 이미지를 분석해 보면 정확함과 차가움의 의미를 지닌 이지적 이미지와 우주의 질서를 반영하는 상징적 이미지, 복잡한 자연으로부터 간결한 형태로의 경향성이 이루어낸 인공적 이미지를 느낄 수 있었으며, 미래적 이미지와 전통적 이미지의 상반된 개념의 이미지를 같이 내포하고 있음을 추론할 수 있었다. 이와 같이 현대 패션에 표현된 기하학적 패턴은 복식을 조형예술 분야로 확실히 인식시키고 발전시키는 데 중요한 촉매제 역할을 담당하고 있으며 또한 많은 디자이너들에게 창조적 욕구를 불러일으키고 영감을 주는데 중요한 모티브를 제공하고 있다.
