생산 기술의 발전과 함께, 날로 다양해지고 복잡해져 가는 소비자의 니즈를 제품 개발 과정에서 반영해야 할 필요성이 점차 높아져 가고 있다. 그러나, 마케팅적 관점에 그 기초를 두고 구조화되고 있는 현재의 소비자 니즈 체계는 제품 개발 단계에서 응용하기에는 너무 추상적이고 범주적인 성격을 가진다. 따라서, 본 연구에서는 인지과학/인지심리학 이론을 중심으로 하여, 제품 컨셉 수립 단계에서 실제적으로 응용할 수 있도록 소비자 니즈를 구조화하는 방법론을 수립하고, 니즈 구조화에 대한 가이드라인을 제시하는 것을 목적으로 한다. 본 연구를 통해 규명된 발견 점은 다음과 같다. 첫째, 기존의 분류 기준과 같이 소비자 니즈의 범주뿐 아니라 실제적인 니즈의 속성까지를 구조화하기 위해서는, 소비자에 대한 제품의 실제적 의미에 해당하는 감성 개념을 구조 내에 포함시켜야 한다. 또한, 이와 같은 개념 하에 수립된 니즈 구조를 감성 니즈 구조라고 정의할 수 있다. 둘째, 개념의 범주화는 상징적 개념을 중심으로 한 본질적 개념과 외연적 개념의 결합을 통하여 이루어질 수 있다. 이러한 가설을 바탕으로 하면, 감성 니즈 구조는 가치 컨셉(본질적 개념), 소비자 니즈(외연적 개념)가 감성(상징적 개념)과 결합함으로써 이루어질 수 있다.

In this study, concept centered approach and process centered approach in developing integrated science curriculum were compared and compromised between two approaches. It seems that two approaches are in antagonistic relations. The superficial conflictions getween two approaches are not because they are antagonistic in their nature, but because their interesting points are different. The concept centered approahc is interest in fundamental scientific concepts and the process centered approach is interested in scientific enquiry. If science is the composition of enquiry processes and concepts produced by enquiry processes, scientific enquiry process and scientific concept must not be inconsistant. Although concepts are not unchangeable, new concepts and advanced concepts are based on the old concepts. Enquiry activity which is not based on concepts also cannot be significant enquiry. Although fundamental concepts in science is very important, in order to apply concepts to varios phenomena, and to understand concepts more deeply the student should understand concept through the process by which the concepts are derived. As we have discussed above, only the concept centered approach or the process centered approach itself is not complete. Comparing these two uncomplete approaches to integrated science curriculum, we can find out that two approaches are in complementary relations. Because integrated science is based on the idea that natural phenomena should not be understood in fragments, but should be understood as mutually related system' the integrated science curriculum includes both the fundamental scientific concepts and scientific enquiry processes.

An improved K-means document clustering method has been presented, where a concept vector is manipulated for each cluster on the basis of cosine similarity of text documents. The concept vectors are unit vectors that have been normalized on the n-dimensional sphere. Because the standard K-means method is sensitive to initial starting condition, our improvement focused on starting condition for estimating the modes of a distribution. The improved K-means clustering algorithm has been applied to a set of text documents, called Classic3, to test and prove efficiency and correctness of clustering result, and showed 7% improvements in its worst case.

The concept of Holon was suggested by A. Koestler in his paper(1967) "The Ghost in the Machine." It became one of the central concept of the Intelligent Manufacturing System. In this paper, a new system concept: Holonic Weapon System was introduced. HWS has the advantages of the holonic system and the system integration technique so that the future unmanned combat system should consider this concept.

New product concept evaluation is one of the most important activities among many possible evaluation activities involved in the whole new product process. This paper aims at exploring the applicability of the Analytic Hierarchy Process(AHP) to this new product concept evaluation. To this aim, an AHP based concept evaluation model was formulated and explained using an illustrative example. A number of issues were also raised and discussed concerning the applicability of AHP to out problem. Finally, some further research areas were identified.

This survey investigated elementary school teachers' Astronomical Spatial Concept and their Attitudes about Astronomy for Effectively Teaching Strategy. This study surveyed 53 teachers in Ulsan. The data were statistically analyzed by SPSS WIN 18.0. The results of this study are as follows : First, Elementary school teachers' level of understanding of the concept of astronomical space, usually lower. In particular, the lower the level of understanding of the concept of spatial location. Second, Elementary teachers' attitudes about astronomy, astronomers generally appreciate the value of the information and guidance, but difficult for astronomers had recognized. Third, the concept of space and astronomy astronomical elementary teacher attitudes about sex and there was no significant difference according to the teaching career. Therefore, in order to develop effective teaching strategies for elementary teachers attitudes about astronomy and astronomical space concepts from their spatial position to increase the understanding of astronomy, often on the job training to strengthen the astronomers should eliminate the difficulties.

The purpose of the present study was to investigate an appropriate instructional model in order to remedy students' misconception. As hypotheses of this study, three instructional models, cognitive conflicting, hypothesis testing, and learning cycle models, on biological 'osmosis' concept were tested in 176 high school students. Results of the present study are as follows: 1. All groups used one of three instructional models showed a statistically significant improvement in conceptual change on the 'osmosis' concept between before and after the instruction. In addition, the three hypothesized instructional models were more effective in conceptual change than a traditional expository instruction. 2. There was a statistically significant difference among three experimental groups. Cognitive conflicting model and hypothesis testing model was more effective than learning cycle models. 3. An interviewing after instruction showed that students who had scientific concept on the 'osmosis' through the instruction could effectively apply the concept to other context more than students who had no scientific concept through instruction. The present study indicated that instructional model play an important role on students' conceptual change in science classroom. According to the result of this study, the instruction emphasizing students' active participation in class and scientific reasoning process is more appropriate to remedy misconception that the instruction using students' passive participation in class and expository teaching procedure. This study also indicated that students' concept acquired through instruction is one of important factors to apply it to other context.

Objectives : This study was designed to signpost the study of brain, intelligence and memory, while interpreting the concept of 'Chongmyeong(聰明)' neotrically and linking it to the clinic of Korean medicine. Methods : In this paper, the meaning of the word 'Chongmyeong(聰明)' is divided into two parts, intelligence and memory. We also explored the relationship between brain science and 'Chongmyeong(聰明)' based on complex system theory, cognitive science and embodied cognition. Results : Through the process of refining the concept of 'Chongmyeong(聰明)' neoterically, we proposed the new method to understand the concept of 'Chongmyeong(聰明)'. Conclusions : The concept of 'Chongmyeong(聰明)' should be interpreted not as a reductionistic viewpoint of brain science but as a viewpoint of brain science based on visual and auditory system and complex system. Human cognition is physically embodied in the environment, from the viewpoint of embodied cognition that it is constituted and formed in an interactive context with society and culture connected with the environment.
