The objective of this study is to explore the strategies to promote the use of the subject guide for Korean modern literature. To meet this objective this study conducted a survey on users' awareness of the subject guide service and sought out experts' opinions to identify the strategies to promote and improve the subject guide for Korean modern literature. The study proposes the following strategies: 1) Conduct promotional activities utilizing a variety of social media; 2) provide education for the user to enhance understanding of the utility of the subject guide; 3) build a website dedicated to the subject guide service for Korean modern literature; 4) provide an efficient subject-specific bibliography service by improving the quality of the subject guide, by offering full texts, ongoing content updates, and coordination with other institutions and agencies; and 5) tailor the service to user characteristics such as gender, age, occupation, and education level. Suggestions for future directions include research on the collaborative system, additional specific promotional strategies to promote the use of the subject guide, and development of evaluation indicators of the subject guide for Korean modern literature.

As topics of researchers become diverse horizontally or vertically, academic libraries have difficulties to identify the dynamic change of researchers' needs for academic publications. This research aims to illustrate the topic areas of researchers in a department of university by analyzing bibliographies of their publications. First, researchers' publications were used to discover the topic areas where the researchers had published. Second, the cited publications in those papers were analysed to identify the expanded topic areas of these researchers. Finally, highly cited journals were analyzed by network analysis method. The major finding is that the importance of topic areas by the number of journals was not necessarily proportional to that by the number of papers. Researchers have a tendency to use many papers in a small number of journals in a certain topic area. Furthermore, the importance of topic areas discovered by researchers' publications was not the same as that discovered by researchers' citations.

The Smartphone, one of essential mobile devices widely used recently, can be very effectively applied to capture knowledge on the spot by jointly applying the pervasive functionality of cloud computing. The process of knowledge capturing can be also effectively automated if the topic of knowledge is automatically identified. Therefore, this paper suggests an interdisciplinary approach to automatically acquire knowledge on the spot by combining technologies of text mining-based topic identification and cloud computing-based Smartphone. The Smartphone is used not only as the recorder to record knowledge possessor's dialogue which plays the role of the knowledge source, but also as the sensor to collect knowledge possessor's context data which characterize specific situations surrounding him or her. The support vector machine, one of well-known outperforming text mining algorithms, is applied to extract the topic of knowledge. By relating the topic and context data, a business rule can be formulated, and by aggregating the rule, the topic, context data, and the dictated dialogue, a set of knowledge is automatically acquired.

Circulation data is a key data set of academic libraries in terms of collection development and service improvement This study aims to identify the characteristics of circulation measures and their feasibility. This study collected the circulation data of 10 colleges in a university and analyzed 4 measures based on the circulation data: circulation frequency, circulation entropy, circulation h-index, and circulation divergence. These measures are to present the circulation topics of each college. This study identified that circulation entropy tends to present general topics which are popular for many colleges, but circulation divergence tends to present specific topics which are preferred by a specific college.

The design of the main control valve, which is the main component of the flap control system, was based on actual manufacturing experience on the basis of trial and error method. In this paper, a model-based part design method is proosed. The flap control system consists of a main control valve, fail-safe valve, solenoid valve, LVDT and force motor. The main control valve consists mainly of a spool and slot. The important design parameters of the main control valve are the slot width, overlap and clearance. AMESim is linked to the model and it analyzes the flow path of the main control valve. Applying the proposed design procedure, it was confirmed that the required performance was satisfied within the allowable machining error range.

최근에는 사람과 기계가 자유롭게 대화를 주고받을 수 있는 자유 주제 대화 시스템(Open-domain Dialogue System)이 다양한 서비스에 활용되고 있다. 자유 주제 대화 시스템이 더욱 다양한 답변을 제공할 수 있도록 사전학습 기반의 생성 언어모델이 활용되고 있지만, 답변 제공의 안정성이 떨어져 검색을 활용한 방법 또한 함께 활용되고 있다. 검색 기반 방법은 사용자의 대화가 들어오면 사전에 구축된 데이터베이스에서 유사한 대화를 검색하고 준비되어있는 답변을 제공하는 기술이다. 하지만 멀티턴으로 이루어진 대화는 일반적인 문서의 문장과 다르게 각 문장에 대한 발화의 주체가 변경되기 때문에 연속된 발화 문장이 문맥적으로 밀접하게 연결되지 않는 경우가 있다. 본 논문에서는 이와 같은 대화의 특징을 고려하여 멀티턴 대화를 효율적으로 임베딩 할 수 있는 DBERT(DialogueBERT) 모델을 제안한다. 기존 공개된 사전학습 언어모델 기반의 문장 임베딩 모델과 비교 평가 실험을 통해 제안하는 방법의 우수성을 입증한다.

The aim of this study is to reveal the categorizational and classificatory features of the subject-based classification (SBC) as a subject organization system. For this purpose, 12 SBC schemes of public libraries were selected and a comparative analysis was made between the traditional classification system, such as DDC and SBC in terms of the categorizational aspects, and canons for the classification. As a result, there were significant and considerable differences between the two types of classifications. This study concluded that SBC cannot be clearly explained and understood without a consideration of its essential and distinctive characteristics as a classification scheme.

다중 문서 제목 추출은 하나의 주제를 가지는 다중 문서에 대한 제목을 추출하는 것을 말한다. 일반적으로 다중 문서 제목 추출에서는 다중 문서 집합을 단일 문서로 본 다음 키워드를 제목 후보군으로 추출하고, 추출된 후보를 나열하는 형식의 연구가 많이 진행되어져 왔다. 하지만 이러한 방법은 크게 두 가지의 한계점을 가지고 있다. 먼저, 다중 문서를 단순히 하나의 문서로 보는 방법은 전체적인 주제를 반영한 제목을 추출하기 어렵다는 문제점이 있다. 다음으로, 키워드를 조합하는 형식의 방법은 키워드의 단위를 찾는 방법에 따라 추출된 제목이 자연스럽지 못하다는 한계점이 있다. 따라서 본 논문에서는 이 한계점들을 보완하기 위하여 단어 관련성 추정과 Byte Pair Encoding을 이용한 요약 기반의 다중 뉴스 기사 제목 추출 방법을 제안한다. 평가를 위해서는 자동으로 군집된 총 12개의 주제에 대한 다중 뉴스 기사 집합을 사용하였으며 전문 교육을 받은 연구원들이 정성평가를 진행하여 5점 만점 기준 평균 3.68점을 얻었다.

The objective of this study is to design an automatic abstracting system through the analysis of natural language texts. For this purpose a knowledge-based system operating on the basis of domain knowledge was developed. The procedure of generating an abstract consists of three steps: (1) A knowledge-base containing domain knowledge necessary to understand a text is constructed using frame and semantic network structures,and preliminary abstracts are prepared for various cases. (2) Input text is analysed on the basis of domain knowledge in order to extract information filling slots of the abstract with. (3) A Preliminary abstract corresponding to the input text is called and filled with the information, completing the abstract.
