본 연구는 인지양식이 온라인 학습의 성취도에 영향을 미치는 요인중의 하나라는 선행연구 결과들을 토대로, 인지양식이 온라인 정보탐색능력에도 영향을 미치는지 그리고 어떤 다른 개인적인 특성들이 온라인 정보탐색행위와 연관성이 있는지 고찰 하였다. 연구 대상은 대학원 석사과정과 박사과정에 재학중인 학생 36명이었으며, 인지양식검사와 Ellis와 Haugan (1997)의 정보탐색행위 모델에 근거하여 연구자에 의해 제작된 설문조사를 실시하였다. 학생들에게 연구 주제를 주고 온라인상에서 정보를 탐색하도록 시켰으며, 이들의 정보탐색행위 과정과 특성을 관찰하고 기록하였다. 인지양식검사 결과와 설문조사 결과를 양적 분석하고, 정보탐색행위 과정과 특성에 관한 질적 분석한 결과에 의하면, 개인의 인지양식과 온라인시스템을 이용한 정보탐색능력과는 아무런 상관관계가 없었다. 반면에, 정보탐색행위는 컴퓨터 이용 능력, 온라인 도서관 시스템 사용경험/능력과 상관관계를 보였다. 또한 검색한 정보에 대한 만족도는 정보탐색에 보내는 시간과 반비례 상관관계를 가지며, 대부분의 학습자들이 총 8단계의 정보탐색과정 중 " Browsing" 단계에 대부분의 시간을 보내는 것으로 관찰 되었다. 끝으로 대부분의 학생들이 도서관 시스템 사용능력에 높은 효능감을 보였지만, 학교 온라인도서관 시스템이 사용하기 편리하지 않도록 설계되어있다고 대답했으며, 자신들의 연구를 위해서 인터넷 검색엔진보다는 도서관 데이터베이스를 더 자주 사용하고 있는 것으로 나타났다.

The purpose of this study is to find important personal characteristics that affect search process and outcome, and to formulate causal models about searching behavior, by examining the channels and the magnitude of the factors identified. The study was designed to conduct a quasi-experiment with 67 student subjects. A total of 29 elements concerned with aptitude, personality, formal education, effectiveness of online training, search process, and search outcome are measured and reduced to 9 variables. 12 hypotheses were tested statistically and path analysis was done to investigate causal relationship among variables. Finally 5 models were formulated.

This study is set out to investigate the factors that influence customers' behavior of choice and switching between online and offline channels, separating the purchase decision into two stages, i.e., information search and purchase. Factors influencing channel choice are found to differ from stage to stage. The main results of this study are as follows. At the information search stage, customers' channel knowledge had impacts on the choice of the channel. Customers are more likely to visit offline bookstores when they have hedonic shopping orientation and higher involvement level with books. On the contrary, customers are more apt to search online when they have a lot of online shopping experiences. At the purchase stage, the results varied according to the search channel. When customers search for information online, the following variables lead to online purchases: online shopping experiences with books, price-focused shopping orientation, and time availability for shopping. Perceived risk made customers purchase offline even though they searched online. In case of offline searching, customers with more convenience-focused, hedonic-focused shopping orientation and less tim availability purchased offline.

Search strategies is a means to make an efficient search. Among several studies of search strategy, Bates' $\ulcorner$Search Tactics$\lrcorner$ has been often cited and introduced, but their studies have been superficial. In this paper, the contents of Bates' $\ulcorner$Search Tactics$\lrcorner$ are examined in detail, and we try to represent the actual online search process based upon Bates' $\ulcorner$Search Tactics$\lrcorner$. The following three kinds of survey are made in order to clarify which and how tactics are used: (1) Interview with 7 searchers who belong to different types of organizations, and use different kinds of databases (2) Analysis of some online search records. (3) Analysis of written applications for a newspaper database during one year. In conclusion, Bates' tactics falls into categories and new several tactics which often used are added. The following five factors affect online search activities, search strategy, and search tactics. (1) the difficulty of search requests (2) the kinds of databases (3) the charging policy for each online search (4) the presence of the user during the search (5) the searcher' online experience In the limited condition, typical tactics are suggested, but in order to generalize the pattern of using tactics, further investigation is necessary.

최근, 온라인 소셜 네트워크 서비스의 사용자가 크게 늘어나면서 온라인 사용자들의 특성을 연구하기위한 방안으로 소셜 네트워크 분석이 주목받고 있다. 그러나 대부분의 소셜 네트워크 분석 방법은 두 노드 사이의 최단경로를 계산해야하므로 계산 시간이 오래 걸리는 단점이 있다. 본 논문에서는 휴리스틱 탐색방법의 하나인 최상우선 탐색 방법을 온라인 소셜 네트워크에 적합하도록 수정한 최단경로 탐색 방법을 제안한다. 제안한 방법은 그래프에서 아크의 개수를 평가 값으로 사용하는 휴리스틱 함수를 사용하며 탐색의 효율성을 위하여 경사트리를 제거한 후 경로를 탐색한다. 그리고 검증을 위하여 약 16만 사용자로 구성된 실제 온라인 소셜 네트워크를 수집하여 너비우선 탐색 방법과 비교 실험을 하였다. 실험 결과, 본 논문에서 제안한 방법이 너비우선 탐색 방법에 비해 정확도는 80% 정도로 다소 떨어지지만 계산 속도가 약 7.4배 향상됨을 확인하였다. 본 논문에서 제안한 방법은 소셜 네트워크 분석의 시간을 향상시켜 여러 분야에서 사회 현상 및 동향을 다양하게 분석하는데 유용하다.

This study explored factors affecting consumer's external information search effort on online shopping malls through three approaches(cost-benefit approach, psychological motivation approach, and web-site theory approach) respectively, and designed the integrative model through searching the relationships among them. In this study search motivation are designed to be explained by search benefit and search cost that are explained by factors related to the web site and search efforts are designed to be explained by search benefit, search cost and search motivation. The results from our empirical research showed that search motivation, search benefits and prior knowledge on online shopping malls have a direct effect on consumer external information search effort. On the other hand, it was verified that the search motivation was affected by search benefits and purchase involvement, and the search benefits are directly influenced by purchase involvement, constructive simplicity, search convenience and trust. In addition, purchase involvement, time press, constructive simplicity and search convenience had direct effects on the search cost.

The purpose of this study is to identify what fields are used to decide how to proceed to the next screen and what factors affect the selection of the fields used on the online catalog system. The initial search option chosen by the users differed statistically according to the type of online catalog system used and the type of query. However, the type of user did not affect the choices of the initial search option. On the citation list screen, the title field was the most frequently used to move to the citation screen. On the citation screen, also, the title field was the most frequently used for confirming a retrieved citation.

Despite the popularity of e-commerce, the understanding of preferred product types for information searches and purchase on the internet are not sufficient. This paper studies the effect of risk perception on information search behavior through online only, offline only, and on-offline together. Specially, this study classifies product types into search goods, experience goods, and credence goods. The study attempts to determine how the relationship between the perceived risk and the information search is influenced by the product knowledge level. The results show that the higher the risk perceptions about experience goods and credence goods, the more the consumer searches information through online and offline together when the consumer's knowledge level is low. When the consumer's knowledge level is high, however, the higher the risk perception regarding search goods, the more the consumer searches information through online only.

This research is speak that is tendencious in comprehension of external consumer information search behavior using on-line external information source to consumers who use on-line that is used as corporations' main strategic means. That is, classify consumer groups which was atomized according to type inflict consumer's information search knowledge level and shopping value study which use on-line, and decision factors of information search that these groups can influence a difference or each group which use information sources grasped what it is. Result that investigate information search knowledge level difference about study finding on-line information source utilization used mainly portal site, comparison site, auction site. And, utilization shopping pursuit value group used information source by portal site, auction site, niche shopping mall site and hedonic shopping pursuit value group used information source by portal site, auction site, shopping mall site. It confirmed that all variables(i.e. consumer-based variable and web site-based variable) are influencing variously in on-line external information search types. Finally, we proposed different way to erect strategic model about consumers that use on-line with study finding that see.

The purpose of this study is to identify how users react with the search options and bibliographic information during search reformulation on the online catalog. Two online catalogs(N0TIS system and Dynix system) were selected and undergraduate students were recruited as the participants for this study. The study shows that the search options and bibliographic information affected the type of the query reformulation and the re-choice of the search options during search.
