This study aims to investigate bibliometric services practices of foreign libraries by service types and suggest practical considerations for Korean libraries wishing to implement bibliometric services. Through the examination of previous research and library websites, nine types of bibliometric services were identified under two broad categories - education & consulting services and research evaluation & research trend services. According to the service types, a wide range of bibliometric services activities were analyzed and described. Recommendations from the study for service development include: building an institutional repository for scholarly output; developing subject guides and education programs at the initial phase of service and providing more advanced services such as consulting and analysis services at the later phase; identifying the potential service needs of researcher groups.

최근 기후변화와 여름철 고온 등으로 인한 녹조현상, 화학물질 및 유류 유출 등 화학사고로 인한 하천의 수질오염과 관련된 사회적 관심이 높아지고 있다. 특히, 화학사고로 인한 유해화학물질 유출은 인체에 접촉 시 악영향을 끼치며, 대기·수질·토양을 오염시키고 주변 농작물의 변색이나 괴사를 유발하는 등의 피해를 야기하기 때문에 적절한 조치와 대응이 필요하다. 환경부에서는 유해화학물질 유출사고로 인한 국민건강 및 환경상의 위해를 예방하기 위해 화학물질관리법과 화학물질 등록 및 평가에 관한 법률을 제정하여 유해화학물질을 관리하고 화학사고에 대응하고 있다. 그러나, 화학사고 발생 시 공장 인근의 먼지, 악취 등을 감시하기 위해 현장인력에 의존하거나 화학물질의 유출이 우려되는 곳에 제한적으로 검출센서를 설치해 사고를 감시하고 있어 검출센서 미설치 지역에 대한 능동적 탐지가 어렵고, 화학물질의 공간적 분포 탐지가 불가능하여 초동 대응에 한계가 있다. 한편 최근 초분광 영상을 활용하여 물질 고유의 분광특성을 분석함으로써 토지피복, 식생, 수질 등의 식별에 활용되고 있다. 따라서 초분광 센서를 활용한 화학물질 감지 가능성도 보여주고 있지만, 초분광 센서를 활용한 하천의 화학물질 감지를 위한 연구는 미비한 실정이다. 이에 본 연구에서는 유해화학물질 18종을 대상으로 초분광 영상을 이용한 상호 구분이 가능한 지 확인하고자 해당 유해화학물질의 초분광 영상을 촬영하여 분광라이브러리를 구축하였다. 또한 물질별 특성을 보이는 분광밴드의 범위를 지정해 특성 분광라이브러리를 구축하였으며, 해당 과정에 대한 표준 및 절차를 제시하였다. 본 연구에서 제시한 절차에 따라 18종의 유해화학물질 분광라이브러리와 특성 분광라이브러리를 구축한 결과, 유해화학물질의 식별 가능성을 확인하였다. 향후 연구를 통해 유해화학물질 분광라이브러리 데이터베이스를 확대하고, 실시간 모니터링에 적용할 경우 신속한 화학사고 발생여부 감지 및 대응에 활용할 수 있을 것으로 사료된다.

조류는 계절별 기상 및 수질 조건에 따라 규조, 녹조, 남조의 발생 및 천이가 이루어지는데 최근 기후 변화로 인해 출연종 별 발생 및 천이의 시기 또한 빨라지고 있다. 이 중 남조류의 경우 초여름에 발생하여 급격한 증식으로 대발생되어 녹조현상을 야기하고 이는 해당 수역의 생태계 파괴, 그 이외에도 사회적, 경제적, 환경적인 측면에서 많은 문제를 유발한다. 하천·호소의 조류의 발생과 거동에 대한 이해와 효과적인 대응책 마련을 위하여 현상에 대한 모니터링이 선행되어야 하지만 기존 조사방식은 점, 선 단위의 간헐적 측정을 통해 진행되고 있어 많은 인력과 시간이 필요로 하고 있는 실태이다. 현재 이에 따른 문제 해결을 위한 하천·호소의 원격탐사 기법을 이용한 조류의 발생 및 거동에 대한 모니터링 연구가 많이 진행되고 있다. 본 연구에서는 초분광 영상을 이용한 원격 탐사 모니터링을 위한 선행연구를 위해 400-1000 nm에서 NIR(visNIR)파장을 분석할 수 있는 초분광 카메라 CORNING사의 micro HSITM 410 shark와 영상 흔들림 보정을 위한 DJI사의 로닌-MX를, 이용하여 현재 녹조류, 남조류 5종의 배양액과 방사보정을 위해 99% 반사율의 반사판과 함께 촬영하여 영상을 수집하였다. 수집된 영상을 통하여 방사보정 및 해당 Base 제거를 통한 조류의 분광 정보 추출 과정을 통해 조류별 분광 정보를 추출, 분석하여 해당 조류의 분광특성을 파악하고 기초 라이브러리를 구축하여 제시함으로 추후 하천·호소에서의 초분광 영상 기반 원격탐사 모니터링에 적용하고자 한다.

High-resolution bathymetry and physico-chemical properties of manganese nodules were explored to identify the relationship between morphological features and nodule occurrences in the KR1, one of the Korean contract nodule fields located in the NE Pacific. The high-resolution seabed mapping showed that the southwestern sector of the KR1 (KR1-1) was relatively deeper than the northeastern sector (KR1-2) which is occupied by small-scale seamounts. In terms of nodule occurrence, manganese nodules in the KR1-1 were comparatively larger (2-4 cm) with rough surface (t-type) and discoidal shapes (D-type), while those in the KR1-2 were generally small (<2 cm) with smooth surface (s-type) and irregular shapes (I-type). In addition, the nodules in the KR1-1 had higher contents of Cu, Mn and Ni. Such connections of water depths to nodule appearances and metal contents are commonly observed in the Pacific nodule fields. On the other hand, the nodules in the KR1-2 tend to be controled by morphological features. The seamounts in the KR1-2 might continuously provide rock fragments as new nuclei of manganese nodules. As a result, the nodules could not grow over than 2 cm and showed the shapes of a newbie (i.e., smooth surface and irregular shapes). As a result, our observations indicate that occurrence features of manganese nodules could be subjected to water depths and seabed morphology simultaneously.

Recently, many attempts have been made to reduce the time required for payment in various shopping environments. In addition, for the Fourth Industrial Revolution era, artificial intelligence is advancing, and Internet of Things (IoT) devices are becoming more compact and cheaper. So, by integrating these two technologies, access to building an unmanned environment to save people time has become easier. In this paper, we propose a smart shopping cart system based on low-cost IoT equipment and deep-learning object-detection technology. The proposed smart cart system consists of a camera for real-time product detection, an ultrasonic sensor that acts as a trigger, a weight sensor to determine whether a product is put into or taken out of the shopping cart, an application for smartphones that provides a user interface for a virtual shopping cart, and a deep learning server where learned product data are stored. Communication between each module is through Transmission Control Protocol/Internet Protocol, a Hypertext Transmission Protocol network, a You Only Look Once darknet library, and an object detection system used by the server to recognize products. The user can check a list of items put into the smart cart via the smartphone app, and can automatically pay for them. The smart cart system proposed in this paper can be applied to unmanned stores with high cost-effectiveness.

This paper consists of two parts: In the first part, we describe our work to build hierarchical knowledge base of digital library patron's research interests and learning topics in various scholarly areas through analyzing well classified Electronic Theses and Dissertations (ETDs) of NDLTD Union catalog. Journal articles from ACM Transactions and conference web sites of computing areas also are added in the analysis to specialize computing fields. This hierarchical knowledge base would be a useful tool for many social computing and information service applications, such as personalization, recommender system, text mining, technology opportunity mining, information visualization, and so on. In the second part, we compare four grouping algorithms to select best one for our data mining researches by testing each one with the hierarchical knowledge base we described in the first part. From these two studies, we intent to show traditional verification methods for social community miming researches, based on interviewing and answering questionnaires, which are expensive, slow, and privacy threatening, can be replaced with systematic, consistent, fast, and privacy protecting methods by using our suggested hierarchical knowledge base.
