Information extraction can facilitate the intensive analysis of documents by providing semantic triples which consist of named entities and their relations recognized in the texts. However, most of the research so far has been carried out separately for named entity recognition and relation extraction as individual studies, and as a result, the effective performance evaluation of the entire information extraction systems was not performed properly. This paper introduces two models of end-to-end information extraction that can extract various entity names in clinical records and their relationships in the form of semantic triples, namely pipeline and joint models and compares their performances in depth. The pipeline model consists of an entity recognition sub-system based on bidirectional GRU-CRFs and a relation extraction module using multiple encoding scheme, whereas the joint model was implemented with a single bidirectional GRU-CRFs equipped with multi-head labeling method. In the experiments using i2b2/VA 2010, the performance of the pipeline model was 5.5% (F-measure) higher. In addition, through a comparative experiment with existing state-of-the-art systems using large-scale neural language models and manually constructed features, the objective performance level of the end-to-end models implemented in this paper could be identified properly.

This paper is a study on a transport robot capable of autonomously driving to a destination using a QR code in an indoor environment. The transport robot was designed and manufactured by attaching a lidar sensor so that the robot can maintain a certain distance during movement by detecting the distance between the camera for recognizing the QR code and the left and right walls. For the location information of the delivery robot, the QR code image was enlarged with Lanczos resampling interpolation, then binarized with Otsu Algorithm, and detection and analysis were performed using the Zbar library. The QR code recognition experiment was performed while changing the size of the QR code and the traveling speed of the transport robot while the camera position of the transport robot and the height of the QR code were fixed at 192cm. When the QR code size was 9cm × 9cm The recognition rate was 99.7% and almost 100% when the traveling speed of the transport robot was less than about 0.5m/s. Based on the QR code recognition rate, an experiment was conducted on the case where the destination is only going straight and the destination is going straight and turning in the absence of obstacles for autonomous driving to the destination. When the destination was only going straight, it was possible to reach the destination quickly because there was little need for position correction. However, when the destination included a turn, the time to arrive at the destination was relatively delayed due to the need for position correction. As a result of the experiment, it was found that the delivery robot arrived at the destination relatively accurately, although a slight positional error occurred while driving, and the applicability of the QR code-based destination self-driving delivery robot was confirmed.

The cooperation between archives and libraries is necessary for the management of limited operational space and the improvement of work efficiency. "Larchive" is one of the model of cooperation between libraries and archives, so it can be an alternative plan for institutions that face difficulties in collaborating through "Larchiveum" - growing model of cooperation between libraries, archives, and museums. This study presents the recognition of Larchive to university archivists and librarians, and suggests a practical operation plan for cooperation between the archive and library. As a result, "Larchive" was relatively less aware of archivists and librarians, but in the practical point of view, respondents were fully aware of the need for cooperation between archives and libraries. In particular, Larchive was presented as a rational alternative model for both of the groups. And the need for material cooperation can be confirmed through the recognition survey, and the improvement plan for business cooperation can be confirmed through the FGI. Some prerequisites are proposed such as securing a collaborative workplace, assignment of budget and manpower. Through the results, this study presented practical operational plans for organizational cooperation in the form of Larchive, focusing on the perspectives of "teaching and learning support", "research support services", "curation services", "collection and management of school history data", "cooperation for evaluation", and drew discussion points.

The purpose of this study is to investigate the effectiveness of education for information literacy by measuring information literacy of selected experimental group and controlled group from university students. Information literacy of each group was measured through structured questionnaires before and after taking the instruction course. The result showed there was a significant difference between two groups after the instruction. and the effectiveness of information literacy showed especially high in the area of information ethics and information analysis. It was also revealed that the education for information literacy is not affected by basic environmental factors at all. Also. students taken the course showed strong self-confidence and positive recognition in information literacy and library use, thus proved that education of information literacy is highly effective both in cognitive and attitudinal side for university students as a liberal arts course.

What is the starting point of discussions for the open access of Korean journals? This study analyzed whether the serials crisis in Western societies are in academic libraries in Korea. The rising of prices of Korean electronic journals in academic libraries and recognition of librarians for it were surveyed. This study found that the subscription fees for web DBs of Korean journals have been increased from 1.3 times to 34 times during the last 10 years. But librarians in the universities did not think that the subscription fees are very high. And the 35% of respondents thought that the subscription fees for the web DBs in academic libraries will be increased to bring to a crisis to libraries. This study suggested that the leading groups of discussions for open access in Korea wilt be interested in the aspects of public goods and social justice, another values of open access.

The purpose of this study is to investigate the factors that affect the educational service of school libraries and to seek effective ways to revitalize the services following an analysis of the influence size and the cause and effect of each factor. For this, after deciding the variables through a comprehensive investigation based on documentary research, the variables were operationalized. These variables are school members' recognition and support, teacher librarians' expertise, cooperation between teachers and teacher librarians, the school curriculum, a shortage of teacher librarians' time, the educational environment and educational services. Fourteen hypotheses on the cause and effect among the seven variables were analyzed by applying SEM (Structural Equation Modeling). The result is that the key factors of educational services are teacher librarians' expertise, cooperation between subject teachers and teacher librarians, and the school curriculum. As a result, active methods for the educational services of school libraries were sought.

The purpose of the present study is to verify the two hypotheses: (1) Online services are fundamentally automated versions of the reference services. Accordingly there will be a major impact on reference services when Online service is introduced into the traditional library environment. The chief impact will be that the use of data bases retrieval service supplements and improves the traditional reference service when Online service is coordinated with the traditional reference service. and is fully incorporated into the existing user service areas. (2) The availability of data bases retrieval service will make it possible for the first time for the reference services to offer substantial search services of any kind resources limited to the printed sources. In light of such circumstances, libraries would provide better service to their users and greatly increase the productivity of reference librarians. There will be also the recognition that a result of an improved professional image for reference librarians and the library heightens user interest. This change may be translated into increased usage of library services generally. To achieve the purpose, 4 Research Libraries adopted Online retrieval from DIALOG's data bases-searching and reference services available in-house were chosen.

The requirements of being archivists and records managers were revised in 2011 and expanded in the scope of their education levels such as having master's or higher degrees in archives and records management, or completion of one year program of archives and records management after having B. A. degree in archival science, history or library and information science with passing of exams recruiting the experts in the field. However, archivists are not much recognized as professionals since there is no definite regulation for being experts in the field. Accordingly, this study aims to put forth the development of their qualification by comparing qualification factors of developed countries for archivists and records managers. Three factors of professional qualification for archivists and records managers are suggested as follows: certification of a standardized curriculum of archival studies, a proposed certification system for the archivists and recognition of working experience and specified duties to the archivists' qualifications as a way to acknowledge career-based expertise.

The purpose of this study is to suggest faculty status for academic librarians in Korea. This will assure the efficient use of academic librarians as human resources for university libraries. To do this, this study reviewed precedent literaturer. Also, the study looked at qualified academic librarians that could be endowed faculty status. Questionnaires were performed and opinions between professor groups and librarian groups were compared. On every question, the two groups responded positively although there were some differences in agreement level on the above questions. Endowing faculty status to academic librarians, who work in university libraries, acts as a motivation, will help to increase the ability of librarians, and increase service quality. This will eventually contribute developing better education and research.
