Recent increase in accessibility to the internet makes it easy to use the internet-connected devices. The internet could allow any user can reach and command any device that is connected to the network. But these teleoperation systems using the internet connected device have several problems such as the network time delay, data loss and development cost of an application for the communication with each other. One feasible solution is to use local and external network line for the network time delay, transmission control protocol for data loss and Java language to reduce the development period and cost. In this study, web-based remote control system using Java language is newly proposed and implemented to a pneumatic servo control system to solve the time delay, data loss and development cost. We have conducted several experiments using pneumatic rodless cylinder through the internet and verified that the proposed remote control system was very effective.

웹은 디지털 정보화 시대에 정보를 제공하는 가장 보편적인 매체이며 이를 통한 정보 습득이 보편화 되어가고 있다. 대학기록관의 웹 기록은 대학이 소장하고 있는 기록물을 이용자가 웹을 통하여 보다 편리하게 이용할 수 있도록 한다. 본 연구는 국내 대학기록관 웹 사이트의 현황을 보다 정확하게 파악하기 위하여 자동화 평가 도구 K-WHA 3.0을 사용한 접근성 평가와 WebQual 4.0을 이용한 사용성 및 정보품질평가를 수행함으로써 객관성과 주관성 각각의 측면을 모두 고려하여 평가결과를 도출하였다. 또한 웹 기록에 대한 관심을 높이고 활용방안을 모색하기 위해 잠재적 이용자들을 대상으로 선정하여 사용자 경험에 기반한 설문조사를 실시하여 각 대학 별 대학기록관의 웹 기록 구축 현황에 대해 평가였으며 이러한 사용성 평가에 대한 분석을 통해 향후 대학기록관 웹 기록 관리의 발전방향을 제안하고자 한다.

웹 접근성은 주어진 웹사이트를 이용할 때 전문적 능력에 관계없이 웹 사이트에서 제공되는 모든 정보에 편리하게 접근하고 이용 할 수 있도록 보장하는 것이다. 최근 전 세계적으로 웹 접근성에 대한 많은 관심과 관련 기술들이 개발되고 있으며, 국내에서도 인터넷 웹 접근성 콘텐츠 접근성 지침이 한국정보통신 표준으로 제정 되어 이를 기준으로 한국형 웹 접근성 평가프로그램이 개발 보급되었다. 또한 웹 접근성 향상을 위한 국가표준 기술 가이드라인이 정해져 공공부문 및 민간 부문에 웹 접근성에 대한 지침 준수를 단계적으로 적용하고 있다. 이에 초등학교는 2011년까지 웹 접근성 지침을 준수해야 하는 상황에 있다. 이에 본 논문에서는 국내 지역별 초등학교 홈페이지의 웹 접근성을 평가 비교하여 국내 초등학교 홈페이지의 웹 접근성에 대한 실태를 확인하였으며, 웹 접근성에 대한 관심을 증가시키고, 웹 접근성의 향상 방안을 제시하였다.

Nowadays, medical services can be performed through online. This entails a lot of human resources and different healthcare information. The rapid changes in the healthcare environment through web should be accounted so that the information would be maximally useful. However, medical information acquired online is not regulated; it is not favorable to users because it creates doubts to its reliability and benefits. This study focuses on the online medical information. It gives help to the users through its accessibility" comprehensiveness, continuity and efficiency. An empirical analysis of research model using PLS(partial least squares) shows that the quality of medical information influences the reliability and benefit of the related medical information. If users recognize medical information to be reliable and beneficial, their intention to use the medical information becomes strong.

최근 DDOS 공격이 활발해짐에 따라 많은 사이트에서 검색 페이지에 노출되지 않도록 웹봇을 차단한 경우가 생기게 되었다. 하지만 이는 사이트 사용자나 사이트 측 모두에게 악영향을 미치므로 웹 사이트의 웹봇 접근성을 평가하는 프로그램을 제작하게 되었다. 본 프로그램은 Robots.txt를 분석하거나 Robots 메타 태크 등을 분석하여 웹 사이트의 웹봇 접근성을 평가하는 프로그램이다. 이 프로그램으로 평가한 결과를 피드백의 근거로 삼아 더 나은 검색 결과를 기대할 수 있다.

웹 접근성이란 장애인, 저사양의 컴퓨터 사용자, 저속 회선 사용자, 노인 등 웹을 사용하는 사용자가 신체적 환경적 요인에 관계없이 웹에 접근하여 이용할 수 있도록 보장하는 것이다. 웹 표준은 표준화기구에서 승인한 개방형 인터넷 표준으로서, 웹 표준의 준수는 기기와 독립적이어서 웹 접근성을 향상시키기 위한 최소한의 선결조건이 된다. 본 논문에서는 얼마나 많은 사이트들이 차세대 웹 표준으로 제안되고 있는 HTML5로 구축되어져 있는가에 대하여 방송통신위원회에서 지정한 국내 주요 100대 사이트와 랭키닷컴(www.rankey.com)의 접속자 수가 많은 국내 100대 사이트들에 대하여 알아보고, 이 웹사이트들에 대하여 웹 접근성 평가를 실시하여 봄으로써 HTML5로 구축되어진 국내 웹사이트들에 대한 웹 접근성 실태에 대하여 알아보았다.

The purpose of this paper is to develop and apply instructional model to improve awareness of information accessibility for gifted students in computer science. The model applied to class is designed based on Problem-Based Learning(PBL). The class was for 42 students(22 elementary school students, 20 middle school students), and the questions, cognition of the necessity for accessibility, behavior intent for accessibility were given before and after class. Additionally, interest, satisfaction and flow were given after the class. The results of this study are as follows. Firstly, it shows a difference on the changes of cognition on the necessity and behavior intent. As a gender difference, specifically, it shows a difference on the cognition of female students's necessity and behavior intent of male students. As a class level difference, specifically, it statistically shows a meaningful difference on cognitive of the necessity of elementary school students and behavior intent of middle school students. Secondly, after class, it shows a high level of interest, satisfaction. But it shows a general level of flow, so various strategies should be developed for covering the flow level.

The web environment is evolving rapidly. Testing in the web based software is an essential process to improve stability and productivity. Testing of complex web contents and ill(user interface) is most important thing. Implemented test cases are efficient when they are automated and reusable. But, most of the testing automation tools are focused on technical accessibility and functions still. A collaboration of the persons concerned and reusability of implemented test case are ignored. In this paper we propose an efficient way to design automated test case in web environment, and to share and pattern automated test cases we introduce testing framework called NTAF(NHN Test Automation Framework.). The NTAF is based on open source framework. It provides integrated testing environment that web testing cane be automated and managed continuously.

In the collaborative product design environment, the communication between designers is important to capture design intents and to share a common view among the different but semantically similar terms. The Semantic Web supports integrated and uniform access to information sources and services as well as intelligent applications by the explicit representation of the semantics buried in ontology. Ontologies provide a source of shared and precisely defined terms that can be used to describe web resources and improve their accessibility to automated processes. Therefore, employing ontologies on assembly modeling makes assembly knowledge accurate and machine interpretable. In this paper, we propose a framework of semantic assembly modeling using ontologies to share design information. An assembly modeling ontology plays as a formal, explicit specification of a shared conceptualization of assembly design modeling. In this paper, implicit assembly constraints are explicitly represented using OWL (Web Ontology Language) and SWRL (Semantic Web Rule Language). The assembly ontology also captures design rationale including joint intent and spatial relationships.

Purpose: The purposed of this study was to develop and evaluate a Web-based for medical terminology educational program. Method: For the development of this program, the NBISD model was applied as a basic model and WBI ID Process Action model was applied. It was executed for 15 weeks along with off-line lectures. After the operation of this program to 210 nursing students, learners' responses were analyzed twice(at 5th week and 15th week). Result: The satisfaction with this program was slightly above the center point. But the structure of system and composition of design were high score. The results of the final evaluation were more positive than those of the interim one. This program have the advantage of easy accessibility and easy understandability with picture and testing. Conclusions: This study proved the importance of the suitability of learning contents and learning form in developing WBI programs and showed possibility for applying WBI to medical terminology. In order to enhance the effects of Web-based medical terminology educational program for, it is necessary to perform analytic comparison with the effect of WBI based on self-directed learning.
