This paper studied the process of changes of the heading which is access point of the catalog in the cataloging Rules. The first described change of the concept of heading, and described change of headings in the Korean Cataloging Rules and Anglo-American Cataloging Rules And then described heading; in the online environment and future of cataloging rules. The concept of the main entry has lost any meaningful purpose in today's online catalog environment despite a multiplicity of definition. To bring cataloging rules up-to-date, Headings of KCR, AhCR2 Chapter 21, the MARC format and KORMARC format need to be revised The revision of this cataloging rules should be based on Hypertext and Hypermedia. A Continued empirical research would be most welcome, and should be incorporated into future cataloging rules.

Recently, research and development for the responsive web is increasing. However, studies of responsive web accessibility evaluation is insufficient. In this study, we evaluated and analyzed the accessibility of Responsive Web site. As a result, accessibility errors were found including providing alternative text of image contents, keyboard access and usage, logical move of the focus and providing the title. These errors can also be responsive web errors. Therefore, it is necessary to supplement and modify them.

This study discusses how players make the mutually cooperative mechanism in Social Games. In SNG, many players exchange helps each other. That mechanism is not only one-off but also repetitive process. In the perspective of reciprocity in Evolutionary psychology and Mythology, this study analyzes mutual cooperation in several game texts most well known in the SNG field. According to the field study results, four cooperative mechanisms were extracted. These 4 principles apply to every digital game design for emerging of cooperative storytelling among players.

최근 인터넷을 통한 언어 교육 연구에 관심이 고조되면서 다양한 언어 학습 홈페이지가 등장하였다. 이 논문은 국어 작문 학습을 목표로 본 연구실에서 개발한 '바른 우리글 쓰기' 학습시스템에 대해 다룬다. 본 학습 시스템은 초보자에서 전문가에 이르는 학습자를 대상으로 우리말로 글을 쓸 때 필요한 우리말 지식을 체계적으로 학습하도록 하거나 학습자가 직접 쓴 문장에서 스스로 오류를 찾아 분석하고 그에 따른 설명 및 글쓰기 규칙을 더 상세하게 알 수 있도록 설계하였다. 학습시스템의 내부 구조를 효율적으로 구성하기 위해 우리말 글과 관련 있는 자료를 수집하여 각각 지식베이스화하고, 학습 내용을 서로 체계적으로 연결하기 위해 우리나라 사람이 자주 틀리는 오류를 중심으로 해당 글쓰기 규칙과 참고 자료와 용례를 하이퍼텍스트화하였다. 이 시스템은 특히 학습 모형에 따라 학습 자료를 재구성할 수 있도록 지식베이스와 모형을 독립하였다. 이와 같이 학습 자료를 풍부하게 준비하고 학습 내용을 구성하는 일 만큼이나 중요한 과제는 학습자의 수준에 맞춰 학습 줄거리를 구성하는 작업이다. 이 시스템에서도 학습자의 특성을 살릴 수 있도록 연역적 학습 모형과 귀납적 학습 모형을 시도하였지만 더 세분화된 학습 줄거리 구성에 대한 연구가 있어야 한다. 따라서 학습자의 학습 동기를 유발할 수 있는 학습 내용과 적절한 기술이 조화를 이룬 홈페이지를 만드는 일이 향후 우리가 지향할 연구 과제이다.

The 2015 revised curriculum aims to cultivate creative convergence talent. In this regard, SW education needs to study various convergence education methods to enhance computational thinking. The purpose of this study is to analyze the effects of SW convergence education centered on reading education and robot utilization education to improve computing thinking ability. For this purpose, SW education teaching and learning was designed by combining SW education using card coding-based robots with reading education based on interactive works and reading on the whole work. As a result, the convergence education between reading and SW improved all three areas of the concept, practice, and perspective of computational thinking ability and increased the learner's satisfaction.

This study examines how OTT service changes the television viewing experience, what are the underlying dimensions that difference of viewing behavior and experiences between OTT service and old television media. The result showed the characteristic of viewing experiences through OTT service that social viewing, channel zapping by sharing information, multi viewing, de-contextualized viewing space. Specifically, television as a family media turned into a personalized media, social viewing generalized so called 'lean forward' with each other using texts and images at the same time. In particular, information on the content and appraisal shared with each other on SNS in real time.

With the rapid development of information technology in 21st century, networks are being used with various devices. Most human actions are processed through cyber space, and it is no longer separate from daily life; it has changed into one of the most important aspects of human life. Unfortunately, in cyber space, certification method has not only technical problems, but also ethological problems. Many users seemed to use the same password throughout several sites. And for a long period they refused to change it or made a small change from the earlier password. This research aims to discuss general factors of choosing and using passwords within information security through statistical analysis.

최근 연구에서 기계학습 중 지도학습 방법으로 개체명 인식을 하고 있다. 그러나 지도 학습 방법은 데이터를 만드는 비용과 시간이 많이 필요로 한다. 본 연구에서는 주석 된 말뭉치를 사용하여 지도 학습 방법을 사용 한다. 의생명 개체명 인식은 Protein, RNA, DNA, Cell type, Cell line 등을 포함한 텍스트 처리에 중요한 기초 작업입니다. 그리고 의생명 지식 검색에서 가장 기본과 핵심 작업 중 하나이다. 본 연구에서는 순환형 신경망과 워드 임베딩을 자질로 사용한 조건적 임의 필드에 대한 성능을 비교한다. 조건적 임의 필드에 N_Gram만을 자질로 사용한 것을 기준점으로 설정 하였고, 기준점의 결과는 70.09% F1 Score이다. RNN의 jordan type은 60.75% F1 Score, elman type은 58.80% F1 Score의 성능을 보여준다. 조건적 임의 필드에 CCA, GLOVE, WORD2VEC을 사용 한 결과는 각각 72.73% F1 Score, 72.74% F1 Score, 72.82% F1 Score의 성능을 얻을 수 있다.

This study compared Author Profiling Analysis(APA) to Author Co-Citation Analysis (ACA). The former is a new analytic technique on the intellectual structure of a science whereas the latter is a traditional analytic technique. The purpose of this study was to propose appropriate methods to analyze intellectual structure of a science in the Korean research environment. In order to achieve the goal, this study adopted APA using Text Mining for analysis on the intellectual structure of a science rather than relying on citation index in order to determine a potential utility of the new analytic technique that can identify the intellectual structure.
