본 연구는 도서관 혹은 정보센터의 중요업무인 문헌탐색을 처리하는데 있어, 어떤 방법이 보다 신속하고 비용이 적게 들며, 효율적인가를 알아보기 위해 수작업탐색과 온라인탐색의 비용·효과를 비교·분석하였다. S대학교 의과대학 도서관에서 MEDLINE 데이터 베이스와 그에 해당하는 색인지 Index Medicus를 이용하여 6개의 질문을 탐색하였다.

This study aims at defining the concept of OPAC, tracing of research trends and development of it, and clarifying various methods of subject access and patterns of bibliographic searching in OPAC as well as strategies for improving to implement online catalogs. Although OPAC is so far the most user-friendly bibliographic searching method, there are still a lot of issues including online subject access in particular. Therefore a more effective and useful method for computer end-users have to be developed, for instance, improvement of an indexing system, a n.0, pplication of the classification system as a searching tool, a new design and construction of standardized thesaurus, betterment of user interface, introducing of expert system into bibliographic searching, establishment of subject authority file. Those would raise the success-rate of users seeking bibliographic information in the library catalogs. Korean libraries are in very early stage of OPAC implementation so that every efforts and concerns to improve strategies and techniques for subject access to OPAC have been strongly asked.

This study is a research on eating-out customer's behavior of inquiring information through the supporting research on the searching information behavior of the customers who visit family restaurants. The result was deduced that the types of eating-out customer's behavior of searching information were different to age, sex, education, incomes, etc., based on demographic analysis. In addition, this study investigated the satisfaction with information and the information types of eating-out customers with verification.

The spatial population existing in a plane ares, such as an animal or aerial population, have certain relationships among regions which are located within a fixed distance from one selected region. We consider with the adaptive searching estimation in spatial sampling for a spatial population. The adaptive searching estimation depends on values of sample points during the survey and on the nature of the surfaces under investigation. In this paper we study the estimation by the adaptive searching in a spatial sampling for the purpose of estimating the area possessing a particular characteristic in a spatial population. From the viewpoint of adaptive searching, we empirically compare systematic sampling with stratified sampling in spatial sampling through the simulation data.

본 연구에서는 국내 주요 검색 포털들인 네이버, 네이트, 다음, 야후, 파란, 구글에서 제공하는 멀티미디어 검색 서비스를 메타데이터, 검색 기능, 검색 방법, 부가 기능, 결과 출력 방식 등의 관점에서 비교, 분석하였다. 조사 결과, 모든 포털들이 이미지, 동영상 검색을 제공하는데 비해 음악 검색은 네이버, 네이트, 다음만이 제공하고 있었다. 또한 음악 검색보다는 이미지, 동영상 검색에서 검색 기능이나 부가 서비스의 개발이 보다 활발하게 진행되고 있었다. 네이버, 네이트, 다음은 국외 검색 포털들이 제공하지 않는 다양한 멀티미디어 검색 기능을 개발, 제공하고 있었고, 구글은 다양한 수준의 고급 검색 기능을 제공하고 있었다. 반면, 국내 포털들은 검색 결과에서 매우 제한적인 메타데이터만 제공하고 있었다. 본 연구의 결과는 포털들의 멀티미디어 검색 서비스의 개선에 활용될 수 있을 것으로 기대된다.

The analysis of spatial search direction and its concentration through eye movement can produce some useful data in that it enables to know the features of space elements and their effects on one another. The results by analysing the search features and concentration of spatial sections through the eye-tracking in shops in a department store makes it possible to define the followings. First, the features of 'eye's in & out' could be estimated through the division of sections by the characteristics of those shops and the extraction of central point based on the decision of continuative observation. The decision of continuative observations enabled to analyse the frequency of observation data which can be considered to be 'things watched longtime' and the stared points that is equivalent to 'things seen very often', by which the searching characteristics of spatial sections could be estimated. Second, as with the eye's [in], the right shops had 0.6 times more (3.5%) than those left and as with the eye's [out] the left ones had 0.6 times more (3.5%). It indicates that [in, out] of the right and the left shops had the same difference, which lets us know that with starting point of the middle space, [in] and [out] were paid more attention to the right shops and the left shops respectively. Third, as with the searching directions by section, the searching times [2.9 times] from [B] to [A] were than that [2.6 times] from [A] to [B]. It was also found that the left shops had more searching direction toward [C, D] than the right ones and that those searching activities at the left shops were more active. Fourth, when the searching directions by section are reviewed, the frequency of searching from [B] to [A] was 2.9 and that of the other way 2.6. Also the left shops were found to have more searching direction toward [C, D] than the right ones and those searching activities at the left shops were estimated to be more active.

Social media have been rapidly and widely adopted in various areas, and tourism industry can be one of potential growing areas. Tourist and travelers would like to share their photos and stories as well as find others' experiences. People are doing their activities through social media. Regarding relaxing entertainments, information sharing, escapism, social interaction, tourism activities are being paid attention by majority of users in social media. However, Although people have various motivation for using social media, academically researchers have not actively studied on the phenomenon arising from tourism industry. Therefore, this study aims to the reasons for tourism information searching motivational factors of social media that influence perceived value and its consequences such like before-searching, during-searching, and after-searching and divided social media into two types according to the level of social presence, and then empirically verified them. Antecedent variables divided into benefits including perceived usefulness and information quality and sacrifices including complexity and perceived effort. Our analysis results show that both of dimensions had the greatest effect on perceived value of social media use, which affect the consequences.

This paper proposes a novel video stitching method that improves real-time performance and visual quality of a multi-camera video surveillance system. A two-stage seam searching algorithm based on enhanced dynamic programming is proposed. It can obtain satisfactory result and achieve better real-time performance than traditional seam-searching methods. The experiments show that the computing time is reduced by 66.4% using the proposed algorithm compared with enhanced dynamic programming, while the seam-searching accuracy is maintained. A real-time local update scheme reduces the deformation effect caused by moving objects passing through the seam, and a seam-based local color transfer model is constructed and applied to achieve smooth transition in the overlapped area, and overcome the traditional pixel blending methods. The effectiveness of the proposed method is proved in the experiements.

정보검색의 성공여부는 적절한 검색어의 선정에 달려있다고 해도 과언이 아니다. 특히 CD-ROM이나 온라인목록시스템에서 주제검색시 분류표, 주제명과 같은 통제어와 자연어 등 비통제어의 비교 우위 문제는 아직도 논란이 되고 있다. 본고는 두 시스템의 검색효율성을 비교하기 위하여 특히 다언어 환경하에서의 검색어 사용에 중점을 두고 다양한 형태의 검색어휘를 조사 분석하였다.

정보의 시각화는 정보의 직관적 이해를 위해 중요한 역할을 하며, 다양한 응용영역에서 해당 환경의 특징에 맞추어 활용되고 있다. 본 논문에서는 전자상거래에서 상품을 효과적으로 검색하여 보여주기 위해서는 기존의 방식이 아닌 상품 정보의 특색에 맞는 검색 방식과 시각화 기법이 필요하다고 판단하여, 기존의 MapNet이나 클러스터맵 등의 기술을 반영한 상품 검색 비주얼라이제이션 기법을 소개한다. 상품 카테고리 검색과 속성 검색의 분리를 통해 검색조건에 명확한 시맨틱 부여를 가능하게 하고, 사용자에게 검색 결과를 평가하고 재검색을 수행할 수 있게 한다. 결과 평가는 원하는 결과를 얻지 못했을 경우 사용자가 질의어를 재작성하여 최적의 결과를 찾을 수 있게 한다.
