With the increased interest in the quality of life of modern people, the implementation of the five-day working week, the increase in traffic convenience, and the economic and social development, domestic and international travel is becoming commonplace. Furthermore, in the past, there were many cases of purchasing packaged goods of specialized travel agencies. However, as the development of the Internet improved the accessibility of information about the travel area, the tourist is changing the trend to plan the trip such as the choice of the destination. Web services have been introduced to recommend travel destinations and travel routes according to these needs of the customers. Therefore, after reviewing some of the most popular web services today, such as Stubby planner (http://www.stubbyplanner.com) and Earthtory (http://www.earthtory.com), they were supposed to be based on traditional Traveling Salesman Problems (TSPs), and the travel routes recommended by them included some practical limitations. That is, they were not considered important issues in the actual journey, such as the use of various transportation, travel expenses, the number of days, and lodging. Moreover, although to recommend travel destinations, there have been various studies such as using IoT (Internet of Things) technology and the analysis of cyberspatial Big Data on the web and SNS (Social Networking Service), there is little research to support travel routes considering the practical constraints. Therefore, this study proposes a new mathematical model for applying to travel route recommendation service, and it is verified by numerical experiments on travel to Jeju Island and trip to Europe including Germany, France and Czech Republic. It also expects to be able to provide more useful information to tourists in their travel plans through linkage with the services for recommending tourist attractions built in the Internet environment.

In recent years, many users preferred video records, and as the broadcasting video data becomes necessary, the demand for video records' use has increased. However, most broadcasters' archive agencies currently provide archive services only for internal employees, and for the general public. In this study, the web-based online information services provided to the general public in the archive sites of domestic and foreign public broadcasting companies were examined and analyzed. The evaluation criteria for the web-based records information services were identified in three service areas: online accessibility, search and online browsing, and outreach or expansion services. The overseas public broadcasters' web-based services and the public broadcasting companies' current status were examined for each area. Based on the examination, direction improvements, such as providing online search and records, developing various outreach services, and expanding user levels were proposed for the information services on broadcasting video data in public broadcasting companies for the general public.

Library of Congress introduced BIBFRAME as a new bibliographic framework to enhance web accessibility of bibliographic records and their integration to Web of data. This study introduces BIBFRAME model and its current status, reviews BIBFRAME classes and properties, and presents a mapping between MARC21 and BIBFRAME. The study aims to help the understanding the deployment of BIBFRAME in bibliographic description. BIBFRAME categorizes bibliographic entities into Work-Instance, and employs RDF/XML and URIs to identify resources and specify semantics of the resources on the Web. It also suggests an Annotation entity to provide additional information produced by users and external organizations. BIBFRAME is significant in that it presents a new paradigm of bibliographic description and expands users' information discovery in the context of Linked Data. Continuous researches are required to support its content model agnostic application to diverse resource type, which may entail a modification of BIBFRAME model and vocabulary. It also calls for guidelines for using the complicated vocabulary in a coherent way.

In this paper, we propose ubiquitous tree management system based on GIS and smart-phone using the object-oriented design modeling to maximize the efficiency of tree management. For this, proposed system is implemented in the form of client/server (C/S). The spot tree management system as the client is based on the mobile(PDA, Smart-Phone), whereas the tree management system based on PC as the server makes use of GIS. Also, Web service method instead of CDMA used in exist studies is used for tree data communication among C/S. And problems of existing studies, that is excessive maintenance costs, accessibility shortage of variety users, connectivity shortage of geographic information system will be settled through the convergence of the proposed system development methods, GIS system, smart devices. Therefore, we verify proposed system by using the systemic unit test and qualitative assessment respectively and prove to be more excellent than the existing system based on the mobile, in terms of systemic effectiveness and extendability.

Persons with low vision impairment refers to visual and visual impairments that can not be remedied by medical or optical methods due to inherited or acquired eye disease. People with low vision impairments account for more than 240 million people in the world and have only a few remaining eyesight. We will discuss the improvement of information accessibility of low visually impaired people and future research methods through research on Web UI/UX in mobile web environment for low visibility handicapped in the environment where information can be accessed through existing screen reader (TTS) and screen enlargement function.

최근 인터넷 환경은 컴퓨터를 이용한 윈도우즈의 환경에서 핸드폰, PDA 등의 모바일 기기를 이용한 다양한 형태로 확산되고 있다. 이로 인해 시각, 청각 장애자나 컴퓨터 초보자도 쉽게 인터넷에 접근할 수 있는 웹 접근성 향상이 많은 분야에서 이루어지고 있다. 이 논문에서는 KADO-WAH 평가도구를 이용하여 교육 관련 기관의 홈페이지를 평가하고 이들 홈페이지의 웹 접근성 지침 준수 여부를 비교 분석한다. 이 논문에서는 교육 관련기관인 대도시 교육청 홈페이지와 부산시 교육청 산하 교육구청의 홈페이지, 그리고 부산시내의 여러 고등학교 홈페이지에 대하여 웹 접근성 지침 준수 여부를 평가하고 비교 분석한다. 그 결과 학부모나 교육 관련 이해 당사자 누구라도 쉽게 교육용 웹사이트에 접근하고 이용할 수 있게 하는데 이 연구의 목적이 있다.

정보통신의 발달은 사람들의 생활양식을 변화시키고 있지만 정보와 환경의 급속한 발전에도 불구하고 장애인, 노인 등은 정보화 혜택을 제대로 받지 못하여 소외되고 있다. 전 세계에서는 이러한 문제를 직시하고 정보격차를 좁히기 위한 한 방안으로 웹 접근성의 문제를 제기했고 꾸준히 해결점을 찾고 있지만 우리나라의 경우 이에 대한 연구 노력은 부족한 실정에 있다. 본 연구에서는 두 가지의 웹 접근성 평가도구를 선정하여 사이버대학 웹 사이트를 중심으로 웹 접근성을 평가해 보고 그 평가도구를 비교 분석함으로써 개선방안을 제시하였다.

지식정보화 시대에서 정보는 사회적 부를 창출하는 수단이며 그 자체로서 가치를 지니기도 한다. 하지만 사회적 약자인 장애인들은 정보접근과 활용에서 소외되고 있다. 이를 해결하기 위해 웹접근성을 향상시키는 것이 중요한 문제이다. 이에 본 논문에서는 웹접근성의 의미와 u-러닝의 의미, 그리고 u-러닝이 주는 학습적 효과를 알아보고 u-러닝 콘텐츠에 웹접근성을 향상시켰을 때 얻을 수 있는 이점에 대해 알아보고자 하며, 장애인의 웹접근성을 향상시키는 u-러닝 콘텐츠를 개발하는 데 목적이 있다. 본 연구에서는 다음과 같은 제안을 한다. 첫째, 시작장애인을 위한 보조기능이 존재해야 한다. 둘째, u-러닝 콘텐츠의 색채구성에 유의해야 한다. 셋째, 청각장애인을 위한 서비스를 제공해야 한다. 넷째, 장애인에게 적절한 모바일 기기를 선택해야 한다.

본 연구는 새로운 딜리버리 채널로 자리잡고 있는 웹사이트의 평가도구를 개발하고 각 웹사이트를 비교 분석하여 상대적 강점과 약점을 파악할 수 있는 방법을 제시하고자 한다. 인터넷 웹사이트 평가 도구는 주관적인 평가요소의 사용을 배제하고 접근성, 속도, 항해성, 컨텐츠 품질 등 객관적 평가도구를 이용하는 상대적 평가방법을 사용하였고, 제안된 평가도구를 이용하여 서울지역 42개 대학교 웹사이트의 상대적인 위치에 따른 평가 및 분석을 실시하였다. 본 연구는 기존의 범용적 웹사이트 평가모델을 이용한 교육기관 웹사이트 평가에서 벗어나 교육기관 컨텐츠 특성에 맞는 평가도구를 제시하였다는 점에서 의의를 가진다.

An expert system for the diagnosis and indication of hypertension is implemented through HTML-based backward inference. HTML-based backward inference is performed using the hypertext function of HTML, and many HTML files, which are hyperlinked to each other based on the backward rules, should be prepared beforehand. The development and maintenance of the HTML files are conducted automatically using the decision graph. Still, the drawing and input of the decision graph is a time consuming and tedious job if it is done manually. So, automatic generator of the decision graph for the diagnosis and indication of hypertension was implemented. The HTML-based backward inference ensures accessibility, multimedia facilities, fast response, stability, easiness, and platform independency of the expert system. So, this research reveals that HTML-based inference approach can be used for many Web-based intelligent site with fast and stable performance.
