Advance of the Internet environment is applied not only to information search but also to the area of consumption behavior. Current research analyzes online use behavior and online information search of consumers in terms of users' perception. With the result of the research, it is noticed that promotion focus brings broader variation of information use behavior, and utilitarian value has a beneficial impact on the online exploratory information search. In addition, it is revealed that the more exploratory the information search is, the wider the range of online shopping information search is. Finally, people who have utilitarian shopping value showed more exploratory behavior in online search, especially for the search of informational products, than those who have hedonic shopping value. Present research is believed to improve practical influence of consumers' personality on online use behavior when customers purchase search products online. As a result, it would contribute to consumer research and marketing held online.

The paper explores how information science knowledge can be used systematically in digital, interdisciplinary research settings and gives a conceptual analysis of the relationship between information science knowledge as donor and other research as receiver in an interdisciplinary project environment. The validity of the approach is demonstrated by the author's work on the project "The Primacy of Tense: A. N. Prior Now and Then." The study proposes a hybrid approach, combining analysis and synthesis. The analytical component identifies information systems, assigns an information system type to them, and accesses the information science knowledge associated with that type. The synthetic part focuses on the connections between information systems according to the receiver discipline's practices. The paper makes explicit the actions of experienced information professionals, thereby making their expertise accessible to others. The analytical and synthetic strategies are explained by linking them to two modes of researchers in the receiver discipline, how they act as researchers and what they know about it. The paper offers information professionals concrete assistance with identification of the appropriate strategy for accessing professional knowledge and taking appropriate actions and development decisions.

The experimental method, when carried out properly, is the most powerful way of seeking answers to research questions. The purpose of this study is to provide practical and theoretical insights as well as to discuss technical skills needed to design and implement the experimental research in library and information science. The levels of empirical research methods, the logic and types of the experimental designs, the application status of the experimental methods through content analysis of the published papers, and strategies to plan the research and to collect and analyze data are examined. This study also brings suggestions how experimental research can be made more meaningful and puts emphasis on the need of the research method education in library and information science field.

In this research we propose a method far rain rate estimation by using Doppler spectrum's data of wind profiler. The Doppler spectrum is used to calculate the wind velocity and wind direction. But in this research uses the parameters from Doppler spectrum, it calculates the rain rate. The rain rate estimation in this method will be compared to the obtained rain rate from the surface rain gauge. Two equipments are installed in the same area. The correlation coefficient between rain rate measuring method is 0.65.

While the body of research on metadata has grown substantially, there has been a lack of systematic analysis of the field of metadata. In this study, we attempt to fill this gap by examining metadata literature spanning the past 20 years. With the combination of a text mining technique, topic modeling, and network analysis, we analyzed 2,713 scholarly papers on metadata published between 1995 and 2014 and identified main topics and trends in metadata research. As the result of topic modeling, 20 topics were discovered and, among those, the most prominent topics were reviewed in detail. In addition, the changes over time in the topic composition, in terms of both the relative topic proportions and the structure of topic networks, were traced to find past and emerging trends in research. The results show that a number of core themes in metadata research have been established over the past decades and the field has advanced, embracing and responding to the dynamic changes in information environments as well as new developments in the professional field.

Since its first release in 2007, the National Institute of Food and Drug Safety Evaluation (NIFDS) has provided pharmacogenomic and comparative information specific to Koreans to allow regulatory reviewers and researchers to adapt their working practices to pharmacogenomics. The highlights of this year's additions include "Drug Information", "Gene Information" and "Pharmacogenomic information in the drug labels" sections. These new additions provide information on 737 genes, 719 drugs and pharmacogenomic data of the labels or relabels of 253 approved drugs as of November 2008. The latest version of the Korean Pharmacogenomic Database (KPD, release 2.0) has expanded significantly since its previous release. More SNP and haplotype information has been added to the database with the latest version of the KPD containing approximately four times as many SNPs and haplotypes than the previous version (719 vs. 152, and 30 vs. 7 respectively). Through the "SNP" and "Haplotype" sections, the KPD provides unique Korean SNP and haplotype information as well as comparative information of other populations (Japanese, Chinese, European, African) to offer a range of pharmacogenomic data that can help reviewers and the public understand pharmacogenomic information. The quality and quantity of information in the KPD has also been improved considerably. This data can be found at: http://www.nitr.go.kr/nitr/contents/m134700/view.do/.

본 연구의 목적은 미국국립의학도서관(NLM)의 Unified Medical Language System(UMLS)에 한의학의 용어를 등재하는 것이다. 1차 등재 대상으로 한국한의학연구원(KIOM)에서 진행중인 한의학 용어 정제 연구 결과물 중 임(任) 독맥(督脈)과 12정경(正經)에 속하는 360개의 경혈명(經穴名)의 Concept Unique Identify(CUI)를 선정하였다. UMLS Knowledge Source Server (UMLSKS)의 메타시소러스 검색을 통해 UMLS 내 경혈(經穴)용어에 대한 terminology정보를 수집, 분석하였다. 이를 바탕으로 용어간 개념 비교를 통해 UMLS의 경혈(經穴)용어와 KIOM의 경혈(經穴)용어를 매핑하였다. 마지막으로 Rich Release Format(RRF)로 데이터를 저장하고, Unicode Transformation Format-8 (UTF-8)로 인코딩하여 NLM으로 송부하였다. NLM에서 용어 등재에 대한 적합성 여부를 판별한 후 2010AB버젼에 "TKMT2010"이라는 소스명으로 한글로 된 한의학 용어가 최초로 UMLS에 등재되었다. 향후 UMLS와 같은 국제표준의학용어와 연계를 통해 한의학 용어가 다양한 의학용어체계와 상호호완성을 확보하고 표준화, 세계화할 수 있도록 지속적인 연구가 필요하다.

The LBS (Location-Based Services) are valuable information services combined the location of moving object with various contents such as map, POI (point of Interest), route and so on. The must general service of LBS is route determination service and its applicable parts are FMS (Fleet Management System), travel advisory system and mobile navigation system. The core function of route determination service is determination of optimal route from source to destination in various environments. The MODB (Moving Object Database) system, core part of LBS composition systems, is able to manage current or past location information of moving object and massive trajectory information stored in MODB is value-added data in CRM, ERP and data mining part. Also this past trajectory information can be helpful to determine optimal route. In this paper, we suggest methods to determine optimal route by querying past trajectory information in MODB system and verify the effectiveness of suggested method.
