이 연구는 예비 중등 교사들을 대상으로 Lakatos의 방법론에 따라서 "계절 변화의 설명"에 대한 대안 모형을 조사하였다. 조사대상은 사범대학 과학교육학부 74명이다. 조사 결과 계절 변화에 대한 예비 중등 교사들의 설명은 과학적 모형과 불일치하는 대안 모형들을 가지고 있었다. 이러한 명백한 불일치의 대안 개념은 어떤 일관성 있는 방향으로, 자신들이 가지고 있는 대안 모형의 핵심 신념을 사용한다고 가정함으로서 설명되어 진다고 우리는 주장한다. 따라서 이 연구에서는 예비 교사들의 대안 모형을 극복하기 위해서 먼저 그들이 가지고 있다고 가정할 수 있는 핵심 신념들과 가능한 근원들을 알아보는 것이다. 그러한 근원들 중에서 교과서가 예비 교사의 대안 모형의 근원을 제공할 가능성을 배제할 수는 없다.

휴대전화 개발의 기획 단계에서 가장 중요한 고려사항 중 하나는 제품의 전략과 목적에 맞는 적절한 형태인자의 선정이며 현재까지는 주로 직관적이고 정성적인 방법을 사용하고 있다. 본 연구에서는 형태인자 선정의 체계적이고, 합리적 방안을 제시하고자, 감성 형용사를 이용하는 평가 방법론을 제안하였다. 우선 공리설계를 사용하여 개념적 형태인자를 검증하고, 검증된 형태인자의 설계파라미터에 감성형용사를 그룹핑 한다. 그 후 디자이너에게 선정된 형태인자와 그룹화된 감성형용사를 제시하면, 디자이너는 예비 디자인을 수행하고, 그 디자인은 설문조사를 통해 평가 및 분석된다. 이와 같은 일련의 프로세스의 적용결과, 공리설계와 감성공학(감성형용사)의 결합으로 제품의 목적에 적합한 형태인자 디자인을 선정할 수 있었으며 향후 휴대전화 개발에 있어 형태인자 이외의 중요 인자의 선정에도 확대 적용할 수 있는 가능성을 확인할 수 있었다.

This study focuses on constructing discourstics utilizing the methodology of linguistic analysis. Discourstics is a theory which analyses meaning and signification through context and discourse. This th∞ry originated from reflections on dichotomy, universalism, reductionism, and how we think of those characteristics as being part of diversity. The integrated study of discourstics is one area of linguistics that main1y deals with the construction of language. 1n discourstics, construction of the process of becoming discourse is examined. 1n view of this, ’text’ is a discourse unit within linguistics, ’statement’ is a pait of the text, ’arrangement (agencement)’ is the method of constructing statements. Contextualization and formation for processing and analyses of discourses are necessary. Contextualizing is the construction of context of the text through which the text becomes concrete. There are three paradigms: the value paradigm, the theme p따adigm， and the subjectivity p따adigm. Mea띠ng is constructed through contextualization and formation. This shows how the context is comprehended and how the meaning of communication through statements and discourse is significant. The effect of discourse strategy results in various signification. Therefore, discourstics is suggested to be an effective tool in analyzing the diversity and complexity of language in a social context.

The article is to find out the task and orientation in Christian missions toward North Korea. First of all, it subscribes the various approaches of Christian missions toward North Korea such as the emic approach, the epic approach, and the holistic approach. Then, it describes the historical changes of the paradigm in the society of North Korea. North Koreans have evaluated Christianity negatively as the spy of the american imperialism. From the end of 1980s, however, they have changed their minds that Christianity must have been a religion of charity for the national unity. Finally, the article concludes that the task and orientation in Christian missions toward North Korea should be cooperative between South and North Korean Christians and future-oriented finding felt-needs of North Korean Christians.

This paper aims to construct an effective decision making model on selection of product design in product development using fuzzy AHP technique. It is expected that this paper contributes to enhancement of company's market competitiveness by shortening the lead time to develop a new product and minimize initial investment. The proposed model using fuzzy AHP enables quick decision making by integrating and analyzing all customer requirements related to a product. In addition, it can deal with vagueness and uncertainty of decision making process using fuzzy set theory. Decision making processes for evaluating the best selection of product design are also constructed to describe the exact concept of development. A tennis racket is shown as an example. The proposed model is expected to be applied in various fields of managerial decision making processes as well as of product development process.

Recently. the severe competition in the internet shopping mall has forced firms to increase the customer satisfaction and to enhance service quality. Despite the internet shopping mall's fast and superficial growth and extraordinary potential, study on fa

Most of people who are engaged in research and development find it difficult to solve the engineering problems creatively due to the lack of ideas. There are two famous methods for inventive problem solving: '"Brainstorming" and "TRIZ" Brainstorming is the most popular tool until now to find a creative solution and TRIZ is not so popular yet but leads us to a very useful and clear solution. These two methods whose goals are the same usually take quite different routes to the final solution; Those routes have their own unique advantages and disadvantages. In this paper, a creative problem solving method optimized by correlating Brainstorming and TRIZ is proposed. And this method demonstrates how rough initial ideas can be quickly refined and how a problem can be solved correctly.can be solved correctly.

In general, data mining has iterative processes with the following five steps: Data Selection, Cleansing, Transformation, Mining, Interpretation. Among these steps, steps of data selection and cleansing are performed to classify data. There are two types of data, continuous data and discrete data. Discrete data has a classified structure and it is easy to obtain rules from data. However, there are no general rules for classified method of data in continuous data. So, the result of data analysis will be differed from the classified method of data in continuous data. This research presents a methodology that can obtain the rules from data and classify data according to situations in DBMS (Data Base Management Systems).

Supplier selection and evaluation are arguably one of the most critical functions for the success of an organization. Thus companies have increasingly considered better supplier selection approaches in order to attain the goals of low cost, consistent high quality, flexibility and quick response. In this paper, we present a measure of the overall reliability performance which is a weighted mean of the process capability indices of the reliability prediction characteristics of a supplier. This measure can be used both as a measure of supplier selection for the customer and as a measure for the self-diagnosis of the reliability prediction performance for the supplier.

Intrusion Detection System (IDS) is intended to detect anomalous usages or attacks on system and network. Even though many IDS models have been developed, they still may have problems, such as involvement of components contaminated by anomalous process, in detecting anomalous behavior patterns. To distinguish anomalous patterns from normal patterns, we propose a Bayesian approach which includes the presentation of the relations among normal pattern components.

This paper investigates the status and change of qualitative research in TEFL and applied linguistics in an effort to project the direction of TEFL research in Korea. This paper first reviews a first and a second coming of age of the research in TESOL and applied linguistics, focusing on qualitative research methodology. For the study, the issues on a definition of qualitative research are raised, and three exemplars such as case study, conversation analysis, and ethnography are discussed in terms of assumptions, methods, data analysis and interpretation, and evaluative criteria. The importance and directions of qualitative research studies in TEFL in Korea are also suggested.

In this paper, a new method of product function analysis is presented to categorize various design information generated in product development processes. In order to improve product functions, designers must understand unit functions and modified parts of products. The product function analysis (PFA) is based on the designer's understanding of product functions. The proposed PFA provides the methodology to classify the various functions systematically and understand the relation between functions easily. Using this approach, efficient design support system can be developed and used for designers to support decision-making with design knowledge.
