This study used text mining to extract 2,842 keywords from 7,397 product names and organized them into categories in order to analyze the characteristics of keywords appearing in the product names of jeans after 2020. The item category included denim and Chungbaji [청바지], and Ilja [일자], while the silhouette category included wide and bootcut. In addition, high-waist and banding comprised the making sector, and the materials category consisted of napping, spandex, and soft blue. Denim surpassed the others in frequency, co-occurrence frequency, and centrality, and co-appeared with various other keywords. Also, the co-appearance of item and silhouette was prominent, and there were many keyword combinations that showed characteristics related to (a) high waist; (b) hemline detail; (c) rubber band; and (d) partial tearing. Furthermore, idiom expressions such as 'slim fit' and 'back tearing', which were not highlighted in the co-occurrence frequency, were additionally confirmed through correlation. Therefore, the product name analysis effectively identified the detailed characteristics of the silhouette and the making of jeans preferred by consumers.

This work presents an exposition of both the internal structure of derived category of an abelian category D^*(𝓐) and its contribution in solving problems, particularly in algebraic geometry. Calculation of some morphisms will be presented between objects in D^*(𝓐) as elements in appropriate cohomology groups along with their compositions with the help of Yoneda construction under the assumption that the homological dimension of D^*(𝓐) is greater than or equal to 2. These computational settings will then be considered under sheaf cohomological context with a particular case from projective geometry.

This study aims to analyze the effect of product information quality and source credibility on product arousal in fresh food website. Despite fresh food websites are selling products with various feature, prior studies have focused on consumer behavior for fresh food website characteristics or specific products without considering the feature of the products. Consumers' attitudes, beliefs, and behaviors vary depending on the feature of the product. In other words, depending on the category of product, the decision making process that consumers purchase products can be differ. So, we classify products considering the feature of these products to examine the effect of information quality and source credibility on product arousal into experience goods and search goods. We surveyed 288 consumers having experience of purchase in fresh food website and verified the hypothesis through One-way ANOVA by classifying the information quality and the source credibility as high level and low level. As a result, there was a difference in product arousal according to the product information quality level and the source credibility level for each product category exposed to the fresh food website. In experience goods, source credibility have a more important effect on product arousal than product information quality, and in search goods, product information quality have a more important effect on product arousal than source credibility.

In this paper we consider the notion of fuzzy relation as a generalization of that of fuzzy set. For a complete Heyting algebra L. the category set(L) of all L-fuzzy sets is shown to be a bireflective subcategory of the category Rel(L) of all L-fuzzy relations and L-fuzzy relation preserving maps. We investigate categorical structures of subcategories of Rel(L) in view of quasitopos. Among those categories, we include the category L-fuzzy similarity relations with respect to both max-min and max-product compositions, respectively, as a cartesian closed topological category. Moreover, we describe exponential objects explicitly in terms of function space.

본 연구는 심리언어학 분야의 개념 결합 이론에서 연구된 서로 다른 2가지 해석 전략(관계 해석 전략 vs. 속성 해석 전략)이 소비자가 가지고 있는 목표의 유형(주 범주 관련 목표 vs. 수식 범주 관련 목표)에 따라 융합제품에 대한 소비자 반응-즉, 융합제품 구성 범주(주 범주, 수식 범주)에 대한 신념 및 융합제품에 대한 태도-에 미치는 차별적 영향을 조사하였다. 두 차례의 실험 결과, (1) 수식 범주 관련 목표 예열 조건의 피험자들은 관계 해석 전략보다 속성 해석 전략을 채용할 때 주 범주와 수식 범주에 대해 전반적으로 모두 높은 신념을 갖는 반면, 주 범주 관련 목표 예열 조건의 피험자들은 주 범주와 수식 범주에 대한 신념에 있어서 속성 해석 전략과 관계 해석 전략 간에 차이가 없는 것으로 나타났으며, (2)수식 범주 관련 목표 예열 조건의 피험자들은 속성 해석 전략 집단과 관계 해석 전략 집단 간에 부분적으로나마 유의한 차이를 보이며 관계 해석 전략보다 속성 해석 전략을 채용할 때 융합제품에 대한 태도가 더 긍정적으로 높아지는 패턴을 갖는 반면, 주 범주 관련 목표 예열 조건의 피험자들은 융합제품에 대한 태도에 있어서 속성 해석 전략과 관계 해석 전략 간에 유의한 차이가 없는 것으로 확인되었다. 마지막으로 본 연구결과가 제시하는 이론적·관리적 시사점을 제시하고, 연구의 한계와 미래의 연구 방향에 대해서도 논의하였다.

This study investigates the importance of brand and retailer associations when consumers evaluate a product category extension in the context of brand and retailer collaborations. Although brand extensions are considered to reduce costs for introducing a new product category, limited study has focused on the role of brand and retailer associations in the context of brand and retailer collaborations. Using a total of 440 participants, a hypothesized model was tested using a structural equation modeling (SEM). The results show that brand and retailer associations influence the perceived fit between a brand and a retailer. In addition, the image fit and quality fit are significantly related to brand and retailer attitudes as well as brand extension evaluation. Since consumers may use their associations with brands or retailers when they perceive product differentiation, market position, and brand extensions, the role of brand or retailer associations is important to marketers, retailers, and consumers. Given the importance of brand and retailer collaborations as a brand positioning strategy in the global branding and retail setting, the findings of this study contribute to brand and retail management by providing empirical evidence on how consumers perceive new products from extended brands in the marketplace when a brand collaborates with a retailer.

Category F Rel of fuzzy sets and relations does not form a topos. J. Harding, C. Walker and E. Walker [3] showed that FRel has a tensor product and V. Durov [1] introduced basic definitions related to the notion of vectoid endowed with a tensor product. In this paper, we show that FRel forms a quasi topos. Also we show that there are quasi power objects in FRel. And by the use of the concepts of FRel and quasi topos, we get the logic operators of FRel. Moreover, we show that FRel forms a vectoid.

In this paper, we introduce the notion of tensor product in groups and prove its existence and uniqueness. Next, we provide the Isbell's zigzag theorem for dominions in commutative groups. We then show that in the category of commutative groups dominions are trivial. This enables us to deduce a well known result epis are surjective in the category of commutative groups.

시퀀스란 두 항목 간의 순서가 존재하는 데이터를 말하며, 고객 한 명이 구매한 상품들이 나열된 구매이력 데이터는 대표적인 시퀀스 데이터 중 하나이다. 일반적으로 모든 상품은 대분류/ 중분류/ 소분류와 같은 상품 분류 체계를 가지며, 서로 다른 상품이더라도 비슷하다면 그 특성에 따라 동일한 범주로 분류된다. 따라서 본 논문에서는 두 구매이력 시퀀스 비교 시 상품의 구매 순서를 고려할 뿐만 아니라, 비교하고자 하는 두 상품이 다르더라도 서로 동일한 상품 군에 속한다면 더 높은 유사도를 부여하여 계산한다. 특히 구매이력 시퀀스 유사도 계산 성능에 직접적인 영향을 미치는 시퀀스 유사도 측정 방법을 선택하기 위해 본 연구에서는 대표적인 시퀀스 간 유사도 측정 방법인 레벤슈타인 거리, 동적 타임 워핑 거리, 니들만-브니쉬 유사도의 성능을 비교하였으며, 항목간의 계층구조도 반영하여 계산하도록 확장하였다. 기존의 유사도 측정 방법의 경우 시퀀스 내 상품 비교 시 상품의 일치 유무에 따라 단순히 0 또는 1의 값을 부여하여 계산한다. 하지만 제안 방법의 경우 서로 다른 상품이더라도 두 상품 간의 연관정도를 다르게 부여하기 위하여 상품 분류 트리를 사용하여 0에서 1 사이의 값을 가지도록 세분화하였다. 실험을 통해 세 알고리즘에 제안 방법을 적용한 경우 기존 방법에 비하여 구매이력 시퀀스 간의 유사도를 더 정확히 측정함을 확인하였다. 또한 정확성 측정 비교 실험을 통해 동적 타임 워핑 유사도가 다른 두 유사도 측정 방법에 비하여 시퀀스 내 상품의 연관 정도를 고려할 뿐만 아니라 두 시퀀스의 길이가 다른 경우에도 좋은 성능을 보였기 때문에 구매이력 데이터에서 시퀀스 간의 유사도 비교 시 가장 적합한 측정 방법임을 확인하였다.
