The purpose of this study was to develop a framework for predicting searching performance through an understanding of how cognitive ability relates to searching process and outcome. Specifically, this study examined the relationship between spatial visualization, logical reasoning, integrative reasoning, and information searching process and outcome. Information searching process was assessed by seven search process indicators: (1) search command selection: (2) combination of search commands; (3) application of Boolean logic: (4) application of truncation; (5) use of limit search function; (6) number of search statements; and (7) number of search errors made. Searching outcome was assessed by the number of correct answers to search questions. Subjects first took three standardized cognitive tests that measured cognitive abilities, and performed online catalog searching in response to seven information search questions. The searches were logged using Lotus ScreenCam, and reviewed for the analysis. Factor analysis was used to find underlying structures of the seven search process variables. Multiple regression analysis was applied to examine the predictive power of three cognitive variables on three extracted factors, and search outcome. Results of the data analysis showed that individual differences in logical reasoning could predict information searching process and outcome.

This study aims to investigate the effects of fashion information search and innovativeness of consumers on service quality of image search. Furthermore, it focuses on exploring the effect of image search service quality on use intention. Data of mobile-friendly consumers in their 20s and 30s was collected in September 2021 via an online survey. Finally, 300 samples were used for the data analysis. First, motivation for information search in fashion was divided into four factors: information, relation, leisure, and entertainment motivation. Furthermore, service quality of image search was divided into four factors: accuracy, convenience, customization, and aesthetics. Second, regression analysis was conducted to evaluate the effect of fashion information search motivation on service quality. As a result, it was found that information, relation, and entertainment motivation except leisure motivation had significant effects on all factors of service quality. Third, fashion innovativeness had no significant effect on aesthetics while consumer innovativeness significantly influenced all factors of service quality. Fourth, accuracy, convenience, and aesthetics had a significant effect on use intention.

The purpose of this study is to examine to what extent the context in which people interact with online information affects people's credibility perceptions. In this study, credibility assessment is defined as perceptions of credibility relying on individuals' expertise and knowledge. Context has been characterized with respect to three aspects: Context as user goals and intentions, context as topicality of information, and context as information activities. The data were collected from two empirical studies. Study 1 was a diary study in which 333 residents in Michigan, U.S.A. submitted 2,471 diary entries to report their trust perceptions associated with ten different user goals and nine different intentions. Study 2 was a lab-based study in which 64 subjects participated in performing four search tasks in two different information activity conditions - information search or content creation. There are three major findings of this study: (1) Score-based trust perceptions provided limited views of people's credibility perceptions because respondents tended to score trust ratings consistently high across various user goals and intentions; (2) The topicality of information mattered more when study subjects assessed the credibility of user generated content (UGC) than with traditional media content (TMC); (3) Subjects of this study exerted more effort into making credibility judgments when they engaged in searching activities than in content creation. These findings indicate that credibility assessment can or should be seen as a process-oriented notion incorporating various information use contexts beyond simple rating-based evaluation. The theoretical contributions for information scientists and practical implications for web designers are also discussed.

Personalized product recommendation service is receiving attention as a new marketing strategy while supporting consumer information search and purchasing decisions. This study attempted to verify the effect of self-reference on service use behavior through the dual path of cognitive attitude and emotional attachment. Using convenience sampling, an online survey was conducted with 324 women who were in their 20s and 30s. After collecting and compiling the survey data, the reliability and validity of variables constituting the conceptual research model were verified through confirmatory factor analysis using AMOS 22.0. Next, the significance of sequentially mediated pathways was verified using Process 3.5 Model 80. The results showed that self-referencing not only significantly affects service use intention by simply mediating cognitive attitudes but also sequentially mediates cognitive attitudes and additional information search. Furthermore, self-referencing was significant as an indirect path to service use intention by mediating additional information search. However, in the path mediated by emotional attachment, self-referencing was considered as a simple mediated path leading to service usage intention. These results indicate a dual path in the psychological mechanism, through cognitive and emotional evaluation, that prompts consumer behavioral responses to the personalized product information provided in the shopping process.

ICT 기술의 발전과 스마트폰 보급의 활성화로 온라인 마켓을 통해 다양한 제품을 구매하는 구매 서비스가 활성화되고 있다. 특히 보관 및 배송 기술의 발전으로 인하여 보관기관이 짧은 식자재의 경우도 온라인을 통해 구매가 가능함으로써 오프라인 판매만을 수행하는 상가의 경우 매출이 감소되고 있는 추세이다. 따라서 본 논문에서는 기존 오프라인 판매만 수행이 가능한 소규모 상가에서 전문적인 판매 지식 및 판매망이 없어도 구매 서비스를 통해 광고 효과 및 주문, 배달이 가능한 통합 솔루션을 제안한다. 제안하는 시스템은 사용자가 원하는 제품에 대한 이미지 검색을 통해 효율적으로 제품에 대한 정보를 카테고리별로 볼 수 있으며, 이로 인해 등록된 제품 판매처가 추가적인 광고가 없어도 효율적으로 판매가 가능하다는 장점이 있다.

This study aimed to examine the effect of ad attributes on engagement, the mediating effect of engagement on the relationship between ad attributes and advertising effectiveness (attitudes toward ads, continuous intention to search, and e-WOM intention), and the differences in advertising effectiveness at different levels (low vs. high) of curiosity toward fashion video ads in the online context. For this purpose, a total of 408 responses were collected from consumers who were aged 20-40 years and had viewed fashion video ads via PC/mobile channels in the preceding six months. The results showed that three advertising attributes, namely informativeness, entertainment, and personalization, were significant predictors of engagement. Additionally, engagement had a significant mediating effect on the relationship between entertainment and ad effectiveness. Moreover, both informativeness and entertainment had a significant direct effect on the behavioral intention to search and engage in e-WOM. At the high-curiosity level, engagement had a significant influence on ad attitudes and e-WOM intention. In contrast, at the low-curiosity level, entertainment had a significant influence on e-WOM intention and continuous intention to search. These findings are meaningful in that they extend the advertising attitude model to fashion video ads in the online context.

온라인 소비자는 쇼핑 웹사이트에서 특정 제품군이나 브랜드에 속한 제품들을 둘러보고 구매를 진행할 수 있고, 혹은 단순히 넓은 범위의 탐색 반경을 보이며 여러 페이지들을 돌아보다 구매를 진행하지 않고 이탈할 수 있다. 이러한 온라인 소비자의 행동과 구매에 관련된 연구는 꾸준히 진행되어왔으며, 실무에서도 소비자들의 행동 데이터를 바탕으로 한 서비스 및 어플리케이션이 개발되고 있다. 최근에는 빅데이터 기술의 발달로 소비자 개인 단위의 맞춤화 전략 및 추천 시스템이 활용되고 있으며 사용자의 쇼핑 경험을 최적화하기 위한 시도가 진행되고 있다. 하지만 이와 같은 시도에도 온라인 소비자가 실제로 웹사이트를 방문해 제품 구매 단계까지 전환될 확률은 매우 낮은 실정이다. 이는 온라인 소비자들이 단지 제품 구매를 위해 웹사이트를 방문하는 것이 아니라 그들의 쇼핑 동기 및 목적에 따라 웹사이트를 다르게 활용하고 탐색하기 때문이다. 따라서 단지 구매가 진행되는 방문 외에도 다양한 방문 형태를 분석하는 것은 온라인 소비자들의 행동을 이해하는데 중요하다고 할 수 있다. 이러한 관점에서 본 연구에서는 온라인 소비자의 탐색 행동의 다양성과 복잡성을 설명하기 위해 실제 E-commerce 기업의 클릭스트림 데이터를 기반으로 세션 단위의 클러스터링 분석을 진행해 탐색 행동을 유형화하였다. 이를 통해 각 유형별로 상세 단위의 탐색 행동과 구매 여부가 차이가 있음을 확인하였다. 또한 소비자 개인이 여러 방문에 걸친 일련의 탐색 유형에 대한 패턴을 분석하기 위해 순차 패턴 마이닝 기법을 활용하였으며, 같은 기간 내에 제품 구매까지 완료한 소비자와 구매를 진행하지 않은 채 방문만 진행한 소비자들의 탐색패턴에 대한 차이를 확인할 수 있었다. 본 연구의 시사점은 대규모의 클릭스트림 데이터를 활용해 온라인 소비자의 탐색 유형을 분석하고 이에 대한 패턴을 분석해 구매 과정 상의 행동을 데이터 기반으로 설명하였다는 점에 있다. 또한 온라인 소매 기업은 다양한 형태의 탐색 유형에 맞는 마케팅 전략 및 추천을 통해 구매 전환 개선을 시도할 수 있으며, 소비자의 탐색 패턴의 변화를 통해 전략의 효과를 평가할 수 있을 것이다.

상수관망이 노후화됨에 따라 파괴나 누수와 같은 운영상의 문제가 빈번하게 발생한다. 따라서 상수관망의 상태를 보다 정확히 파악하여 운영할 경우 안정적인 상수관망의 운영이 가능할 것이며 관파괴와 같은 돌발적인 사태의 피해를 최소화 할 수 있을 것이다. 그러나 상수관망의 실시간 모니터링 센서중 대표적인 online 압력계를 모든 지점에 설치할 경우 과다한 초기투자 비용이 소요되며 시스템의 유지관리 측면에서도 적절하지 않다. 따라서 본 연구에서는 상수관망의 실시간 모니터링을 위한 적정한 규모의 online 압력계 설치위치의 결정 방법을 제안하였다. 제안된 방법은 영향행렬지수(Effect Index Matrix)를 기반으로 하며 영향행렬지수내 column search를 수행하여 online 압력계의 위치를 선정한다. 제안된 방법을 미국의 Cherry Hill 상수관망에 적용하여 적용성을 검증하였다.
