  • The purpose of this paper is to derive an optimal route for foreign tourists in Korea. To that end, the data gained from domestic tourist portal sites was analyzed with a big data analytics tool R. The destinations most visited by inbound foreign tourists, the shortest route and the most economical route were derived from the analysis results. The findings suggest original Korean culture is the factor for successful tourist destinations and relevant products, and will serve as some reference data conducive to planning the tourist products in practice.

  • This study proposes a way to timely forecast open government data (OGD) demand(i.e., OGD requests, search queries, etc.) by using keyword network analysis. According to the analysis results, most of the OGD belonging to the high-demand topics are provided by the domestic OGD portal(data.go.kr), while the OGD related to users' actual needs predicted through topic association analysis are rarely provided. This is because, when providing(or selecting) OGD, relevance to OGD topics takes precedence over relevance to users' OGD requests. The proposed keyword network analysis framework is expected to contribute to the establishment of OGD policies for public institutions in the future as it can quickly and easily forecast users' demand based on actual OGD requests.

  • Objective: The aim of this study was to provide a systematic review of the Korean literature on the influence of herbal medicine on liver function. Additionally, we tried to estimate the change in the data on liver function tests (LFTs) and the incidence of liver injury (LI) after taking herbal medicine. Methods: Systematic literature searches were performed on 6 major Korean databases (Research Information Sharing Service (RISS), Korea Institute of Science and Technology information (KISTI), National Assembly Electronic Library, Korean Medical database (KMBASE), Korean Traditional Portal, and Dongui University Electronic Library) from January 2010 to June 2020. No restrictions were placed on the types of publications, which included grey literature. Results: The data indicate that herbal medicine might be a minor cause of LI in Korea. However the results are not supported strongly enough to verify the safety issues because of the limitations of the original studies. Conclusions: Additional well-planned studies are still needed that can overcome the heterogeneity and the considerable methodological flaws in the analyzed studies.

  • This study would understand the overall perception of our society about public libraries, analyzing the texts related to public libraries, utilizing the semantic connection network & sentiment analysis. For this purpose, this study collected data from the last five years with keywords, 'Library' and 'Lifelong Learning Center' from January 1, 2016 through November 30, 2020 through the blogs and cafés of major domestic portal sites. With the collected data, text mining, centrality of keywords, network structure, structural equipotentiality, and sensitivity analyses were conducted. As a result of the analysis, First, 'reading' and 'book' were identified as representative keywords that form the social perception of public libraries. Second, it turned out that there were keywords related to the use of the library and the untact service due to the recent spread of COVID-19. Third, in seeking a plan for the development of public libraries through the keywords drawn to have positive meanings, it is necessary to create continuous services that can form a new image of the library, breaking away from the existing fixed role and image of the library and increase the convenience of use. Fourth, facilities and facilities for library services were recognized from a neutral point of view. Fifth, the spread of infectious diseases, social distancing, and temporary closure and closure of libraries are negatively related to public libraries, and awareness of librarians has been identified as negative keywords.

  • The exponential increase of digital contents brought about the e-Challenge crisis to the librarians. How can all the e-resources be managed effectively? How can we detect all the broken links? How can we assist the users to the right resources? This paper concentrates on building CLICK(Cooperative Link Center in KOREA) as a knowledge compass by collecting diverse science & technology information and creating tight coupled links between information resources for reference linking and providing users with the optimal route for the resource per user. If the publishers, Abstract & Index DB, Searching Portal, Electronic Libraries, Full-text DB and Aggregator can be linked by using a standardized way through a CLICK, the service channels can be diversified. Users can select the channels without rein under according to a use purpose and conditions.

  • Among the various methods for identifying users's information needs, Log analysis methods can realistically reflect the users' actual search behavior and analyze the overall usage of most users. Based on the large quantity of query log big data obtained through the portal service of the National Archives of Korea, this study conducted an analysis by the information type and search result type in order to identify the users' information needs. The Query log used in analysis were based on 1,571,547 query data collected over a total of 141 months from 2007 to December 2018, when the National Archives of Korea provided search services via the web. Furthermore, based on the analysis results, improvement methods were proposed to improve user search satisfaction. The results of this study could actually be used to improve and upgrade the National Archives of Korea search service.

  • Spill of personal information using a stolen ID and password that recently occurred in large enterprises and portal web site such as Nate, Auction, National Agricultural Cooperative Federation, suggesting the importance of protecting personal information. By managing access to user accounts in real time, users will be able to block access before personal information is leaked. Therefore, In this paper, we propose a method to prevent spill of personal information that may occur when connected to others by using an authorized ID and password from portals. Specifically, we offer a mobile status control app that controls the logged status of user account in real time to view login status information to user by visualization and information about specific time and IP address. Also, we propose a method for detecting and blocking duplicated login that connect via IP address change.

  • With the rapid distribution and active usage of the Internet, information search and retrieval through Internet has become a primary form of information access. This ubiquity of information access through Internet means the increased significance of search performance offered by Internet portals, since the optimization of search performance by portal has strong implication for the effective access of information through Internet in general. In this context, this paper investigates the classification scheme used in the directory service of internet portals, which provides selected and organized access to Internet information. First, the author analyzes the deployment of directory classification of standard subdivision topics used in traditional library classification system, with emphasis on the table composed of the form and approach, which are applicable to diverse subject areas. Then, based on this analysis, he proposed a method of applying certain subdivisions of the standard subdivision to directory service of Internet portals.

  • Recently, according to the establishment of personal information protection Act, the public and private organizations are taking a step to protect personal information rights and interests by employing the technical methods such as the access control mechanism, cryptography, etc. The result of the personal information leakage causes a serious damage for the organization image and also has to face with the responsibility by law. However, applying access control and cryptographic approach on the personal information item for every connection to large database system causes significant performance degradation in a large database system. In this paper, we designed and implemented the light weight system using JVM (Java Virtual Machine) for the Oracle DBMS environment which the concurrent transaction occurs many, thereby the proposed system provides the minimum impact on the system performance and meets the need of personal information protection. The proposed system was validated on the personal information protection system which sits on a 'A' public organization's portal site and personnel information management system.
