The purpose of this study was to identify the relationship of clothing involvement and clothing buying behavior of women. A questionnaire was developed to measure clothing involvement, clothing purchasing motives, clothing purchasing criteria, fashion information sources, store selection criteria, and demographic characteristics. The questionnaire was administered to 430 female adults in Taegu. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were s follows: 1. Subjects were divided into low clothing involved and high clothing involved groups. 2. Three dimensions of clothing purchasing motives were derived by factor analysis such as Aesthetic dependant, Impulsive, and Practical motive. Clothing purchasing criteria were factor analysed as Aesthetic, Qualitative, External, and Economical criterion. Fashion information sources were factor analysed as Printed & audio-visual oriented media, Marketer intensive search, Store search, Observation & Interpersonal search, and Experience. Store selection criteria were factor analyzed as Merchandise & Store atmosphere, Store convenience, and Brand & fashion. 3. There were significant differences between high involved and low involved consumers in clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about purchasing criteria expecially in aesthetic dependant. The high involved consumers put more importance to aesthetic, qualitative, and external criterion as clothing purchasing criteria. The high involved information sources. The high involved consumers were more concerned about merchandise & store atmosphere, and brand & fashion than low involved consumers in store selection criteria.

본 논문에서는 실시간 동적 환경에 효과적인 L-CAA 에이전트 구조를 제안한다. L-CAA 에이전트 구조는 변화하는 환경에 대한 적응성을 높이기 위해, 선행 연구를 통해 개발된 행위기반 에이전트 구조인 CAA에 강화학습 기능을 추가하여 확장한 것이다. 안정적인 성능을 위해 L-CAA 구조에서는 행위 선택과 실행을 학습에 전적으로 의존하지 않고 학습을 보조적으로 이용한다. L-CAA에서 행위 선택 메커니즘은 크게 두 단계로 나뉜다. 첫 번째 단계에서는 사용자가 미리 정의한 각 행위의 적용 가능 조건과 효용성을 검사함으로써 행위 라이브러리로부터 실행할 행위들을 추출한다. 하지만 첫 번째 단계에서 다수의 행위가 추출되면, 두 번째 단계에서는 강화학습의 도움을 받아 이들 중에서 실행 할 하나의 행위를 선택한다. 즉, 강화학습을 통해 갱신된 각 행위들의 Q 함수값을 서로 비교함으로써, 가장 큰 기대 보상값을 가진 행위를 선택하여 실행한다. 또한 L-CAA에서는 실행 중인 행위의 유지 가능 조건을 지속적으로 검사하여 환경의 동적 변화로 인해 일부 조건이 만족되지 않는 경우가 발생하면 현재 행위의 실행을 즉시 종료할 수 있다. 그 뿐 아니라, L-CAA는 행위 실행 중에도 효용성이 더 높은 다른 행위가 발생하면 현재의 행위를 일시 정지하였다가 복귀하는 기능도 제공한다. 본 논문에서는 L-CAA 구조의 효과를 분석하기 위해, 대표적인 동적 가상환경인 Unreal Tournament 게임에서 자율적으로 동작하는 L-CAA 기반의 에이전트를 구현하고, 이를 이용한 성능 실험을 전개해본다.

Since personality lead to relatively consistent responses to one's own environment, consumers' distinct personality influences their buying behavior. In order to understand the relationship between consumer's personal characteristics and purchase behavior, the study investigated the effect of consumers' personality trait on the clothing selection criteria and preferred clothing image. Survey was utilized to collect the data and subjects were 333 high school students. Measures consisted of three main constructs: Consumer's extroversion and openness based on the Big-Five personality trait, clothing selection criteria, and preferred clothing image. The data were analyzed using PRELIS 2, LISREL 8.8, and SAS 9.2. The subjects was classified into three groups; Group 1 was a group of intermediate-level in openness and extroversion while Group 2 was a group of high-level in both personality traits. Group 3 was a group of high-level in openness but of low-level in extroversion. Clothing selection criteria were confirmed to have five constructs: other-directed, aesthetic, fashion & conformity-oriented, brand-oriented, and practical. In the buying situation, Group 1 prioritized fashion & conformity-oriented and brand-oriented criteria but regarded other-directed and aesthetic as less important than other groups did. Group 2 considered that all of the clothing selection criteria were important except practical. "The were six factors in the clothing image: elegance, simple, ethnic, masculine, active, and modem. The result showed a significant difference between groups in preferred clothing images. Group 2 liked most of the clothing images but group 3 did not. Group 3 preferred simple clothing image more than masculine or ethnic ones. Overall, the study concluded that the openness and extroversion of Big-Five personality traits could serve as a predictor of clothing selection criteria and preferred clothing image.

독서동기 유발요인과 도서선택 요인은 서로 밀접하게 연관되어 있다. 그럼에도 불구하고 이러한 요인들을 포괄적으로 식별한 연구는 거의 없는 편이다. 따라서 본 연구에서는 고등학생들의 독서동기 및 도서선택에 영향을 미칠 수 있는 요인을 통합적으로 식별하고자 하였다. 이를 위하여 인문계 고등학교에 재학 중인 고등학생 15명을 대상으로 심층 면담을 실시하였고, 이를 바탕으로 독서동기 및 도서선택에 미치는 요인들을 분석하였다. 연구결과, 고등학생들의 독서 행태에 영향을 주는 요인의 유형은 정보원의 특성, 개인적 요인, 가정환경 요인, 학교 및 학습환경 요인, 사회환경 요인으로 나타났다. 특히 이러한 요인들은 복합적으로 작용하여 독서동기나 도서선택에 영향을 줄 수 있음을 알 수 있었다. 더 나아가 독서동기는 도서선택의 선행조건임을 알 수 있었고, 독서동기의 유발이 도서선택을 보장하는 것은 아닌 것으로 나타났다. 본 연구에서 식별된 각 요인들은 고등학생들의 독서행태를 보다 깊이 이해하여 독서지도에 활용하고 새로운 프로그램을 개발하는데 도움이 될 것이다.

For action selection as well as learning, simple associations between stimulus and response have been employed in most of literatures. But, for a successful task accomplishment, it is required that an animat can learn and express behavioral sequences. In this paper, we propose a novel action-selection-mechanism to deal with sequential behaviors. For this, we define behavioral motivation as a primitive node for action selection, and then hierarchically construct a network with behavioral motivations. The vertical path of the network represents behavioral sequences. Here, such a tree for our proposed ASM can be newly generated and/or updated, whenever a new sequential behaviors is learned. To show the validity of our proposed ASM, three 2-D grid world simulations will be illustrated.

Nonparametric kernel regression has recently gained widespread acceptance as an attractive method for the nonparametric estimation of the mean function from noisy regression data. Also, the practical implementation of kernel method is enhanced by the availability of reliable rule for automatic selection of the bandwidth. In this article, we propose a method for automatic selection of the bandwidth that minimizes the asymptotic mean square error. Then, the estimated bandwidth by the proposed method is compared with the theoretical optimal bandwidth and a bandwidth by plug-in method. Simulation study is performed and shows satisfactory behavior of the proposed method.

This study proposes hybrid case-based reasoning and genetic algorithms model for customer classification. In this study, vertical and horizontal dimensions of the research data are reduced through integrated feature and instance selection process using genetic algorithms. We applied the proposed model to customer classification model which utilizes customers' demographic characteristics as inputs to predict their buying behavior for the specific product. Experimental results show that the proposed model may improve the classification accuracy and outperform various optimization models of typical CBR system.

The economic behavior of individuals' selection of particular kye and positions in a kye is based upon choice criteria. The selection of a kye or a position in a kye is not the same as an investor's portfolio selection. A kye member combines in varying degrees the characteristics of both a borrower and a lender of funds. In the following sections we shall first propose choice criteria for borrowers and lenders of funds, then we will try to test various hypotheses derived from the choice criteria by empirical data.
