The purpose of this study was to understand mechanisms of scientific discovery and how this can help students, as young scientists, to understand scientific ideas in the science classroom. To unravel this mechanism, this study employed the notion of chaos. This phenomena was rediscovered by Edward Lorenz. In this paper, the general concept of chaos was briefly discussed in relation with previous scientific theories such as Newtonian physics and quantum mechanics. Following this, discovery constraints in terms of available technology at the time was described. In addition, Lorenz's psychological processes during the discovery was also discussed. Based on analysis, major implications for the field of science education were the provision of relevant schemata, the use of cognitive tools, the presentation of problems with various representational forms, and the sharing of ideas with others.

In the context of total quality management, customer satisfaction is a key factor of success. Customer needs have been in the past described with rather vague words. In order to lead in the competitive market, product designers must be willing to interpret and reflect customer perceptions of a product on the design. The objective of this research is to develop a systematic process capable of linking customer preferences on a product to the design of product elements or specifications. The design process consists of multivariate statistical analyses, semantic differentials, and multidimensional scaling techniques under the framework of a methodology known as quality function deployment which is frequently used to construct a quality design process. The process being established is expected to serve as an effective means to communicate between the customer and the designer through proper representational schemes of design elements.

This study examined the development of children's theory of mind by types of false-belief tasks and various mental states. Seventy six 3-, 4-, 5- and 6-year olds were asked to infer others' minds or choose other's behaviors. Ten tasks, including two picture book tasks, were used to tap the children's understanding of various mental states. Results showed that children did well in their understanding of diverse perception and desire, but they did poorly in emotional inference based on false-belief, and second order false-belief. Children performed better in picture book tasks than in classical tasks for the understanding of false-belief and false-belief based emotion.

Pattern recognition is one of the most common problems encountered in engineering and scientific disciplines, which involves developing prediction or classification models from historic data or training samples. This paper introduces a new approach, called the Representational Capability (RC) algorithm, to handle pattern recognition problems using radial basis function (RBF) models. The RC algorithm has been developed based on the mathematical properties of the interpolation and design matrices of RBF models. The model development process based on this algorithm not only yields the best model in the sense of balancing its parsimony and generalization ability, but also provides insights into the design process by employing a design parameter (${\delta}$). We discuss the RC algorithm and its use at length via an illustrative example. In addition, RBF classification models are developed for heart disease diagnosis.

The topic of selection of a grammatical subject in a correlative conjunction phrase has long failed to attract the attention of linguists due to some difficulties not only in figuring out the internal structure of NP's conjoined by a correlative conjunction but also in its heavy dependency on the representational aspects each correlative conjunction demonstrates. In this paper, I have explored the seemingly complex patterns in the selection of a grammatical subject in a correlative conjunction phrase in the frame of the Optimality Theory (Prince & Smolensky 1993, 2008). I show that, with the help of three newly developed constraints such as MinDist, Focus, and PARSE which are ranked relatively to each other, an optimal grammatical subject out of two NP candidates conjoined by a correlative conjunction can be correctly selectable.

Effective management of knowledge is essential to keep up with demands of this challenging information age. The first step for this kind of management would be to define indicators to evaluate the quality of knowledge. In this paper, we use five latent variables (intrinsic quality, representational quality, ease of use of quality, maintainable quality, usage of quality) as basis for a preliminary path analysis for knowledge management. Preliminary study results showed that high intrinsic quality does not necessarily guarantee high frequency of use. A modified questionnaire is made and is used for SERVQUAL. The result of SERVQUAL shows that customers are not relatively happy about both intrinsic quality and its ease of use. Additional path analyses are done for both expected and observed quality indicators. The path model based on the expectation indicated that the presentation method of knowledge would induce its easy maintenance while that based on observation did not back up the same phenomenon.

This paper first discusses the existing non-homogeneous Poisson process(NHPP) software reliability growth model(SRGM) frameworks with respect to capability of representing software reliability growth phenomenon. As an enhancement of representational capability a new general coverage-based NHPP SRGM framework is developed. Issues associated with application of the new framework are then considered.

최근 바이오인포매틱스의 발전과 함께 생물 관련 정보들이 기하급수적으로 증가하고 있다. 연구 대상도 DNA, RNA, 단백질에서 더 나아가 이들의 상호작용 및 조절 메커니즘에 의해 기능들이 어떻게 수행되는지에 관한 Biopathway까지 포함하게 되었다. Biopathway는 광대한 양의 정보를 포괄하며 구성체 사이의 유기적 관계를 나타내고 있는 것이므로 다양한 형태의 지식을 통합하며 지식의 특성에 맞게 정보를 관리하고 표현함으로써 컴퓨터 프로세싱을 용이하게 하여 정보의 부가가치를 높이는 것이 중요하다. 이러한 Biopathway를 지식표현 관점에서 체계화하고 이를 확장함으로써 궁극적으로 바이오 정보의 거대한 지식베이스를 형성할 수 있다. 본 논문에서는 다양한 종류의 Biopathway 지식을 프래임 형식에 기반하여 보다 명료하고 효율적으로 표현할 수 있는 UniPath 표기법을 제안하였다. 또한 이 표기법을 적용하여 Biopathway 지식을 그래프 형태로 편집함으로써 그 정보를 등록하며, XML 포맷으로 쉽게 변환할 수 있는 시스템을 설계하고 실제 데이터에 적용함으로써 타당성을 검증하였다.
