Recent commencement of digital broadcasting has enabled various TV programs through hundreds of channels. As a result, it becomes a time-consuming job for the TV audience to look up newspaper or TV magazines for the schedule of a specific TV program. To relieve this problem, digital broadcasting usually provides an EPG(Electronic Program Guide) for the audience. Currently. most EPG services are focusing on the visual delivery of information through a web site, digital TV or mobile devices. However, this approach could cause a serious restriction to some users including drivers or visually handicapped persons, who can't input keywords for the search. In order to solve this problem, in this paper, we propose a VoiceXML-based EPG retrieval system that enables even such special users to browse EPG. conveniently using a mobile phone. We implemented a prototype system and proved its effectiveness through experiments.

The purpose of this study is to research on usability of Seoul Bike focusing on seoul citizens over-50s. Before the test, I researched Seoul Universal Design Guideline's background, purpose, principle and range through literature review. Then I did two tests based on re-establishment of the existing principle to fit the public service. First, I have noticed that using the service through an application was difficult for seoul citizens over-50s even if they have NEEDS for using Seoul Bike according to the survey. Next, I drew the result from User Task Evaluation Analysis. Due to the low app usability(the main point of the service) and accessibility and usability status was rate low, but the overall service process was comfortable and convenience. I expect this study will be a good resouce for public service design.

한국향토문화전자대전은 각 지방의 역사와 문화 유산을 비롯하여, 정치 경제사회의 변화 발전상에 관한 모든 정보를 집대성한 지역 문화 콘텐츠 디지털 백과사전을 말한다. 본 연구는 국내 각 지방의 지역 문화 콘텐츠를 디지털 정보시스템으로 구축함에 있어 적합한 인터페이스의 개발을 위해 진행된 시범 서비스의 사용성 평가에 관한 연구이다. 2003 년 6 월부터 2004 년 12 월까지 경기도 성남시 지역을 대상으로 개발된 디지털성남문화대전에 대하여 전반적인 서비스 및 시스템, 인터페이스 등에 대하여 사용성 평가를 실시하였다. 12 개의 콘텐츠 접근방법에 대하여 5 명의 피실험자를 대상으로 한 자유테스트와 15 개의 태스크로 실험된 수행도 평가를 진행하였다. 4 명의 인터뷰 참여자를 대상으로 FGI 를 실시하고, 테스트의 모든 참여자를 대상으로 한 설문조사를 통해 전반적인 만족도와 선호도를 분석하였다. 평가 대상 서비스에 대한 시스템, 사용자, 인터페이스, 콘텐츠 영역으로 나누어 문제점을 도출하였으며, 이는 시스템 설계와 세부적인 인터페이스 개선에 제안되었다. 특히 평가 결과 도출된 네이밍의 문제와 사용자 가이드, 메뉴 및 네비게이션 체계 등 인터페이스 설계에 대한 개선은 향후 10 년 동안 구축 될 한국향토문화전자대전을 기획하는데 실증적 기초 연구자료가 될 것으로 기대된다. 이는 구체적으로 2005 년 청주지역 및 지속적으로 개발되어가는 사업의 서비스, 인터페이스 기획 및 개발에 기초 가이드라인으로 사용되고 있다.

This paper concerns the cultural tourism and the importance of cultural interpreters. Globalization has become a key word of 21st century, so the volume of tourists has been increasing. Furthermore, as the Korean wave has expanded to the world, more people are interested in Korea and Korean culture, and we observed the obvious increase of tourists. International tourists visit Korea with a variety of purposes, and their travel types are also diversified. This paper analyzes tourists' behavior based on the data provided by KNTO and briefly examines the cultural interpreters in 5 major organizations. Then considering the specific roles of the guides based on the Cohen (1985) and Lee (2011), I propose that the government should give more focus on the professional foreign language speaking interpreters for culture. As for an alternative to the present volunteering system for foreign languages, I strongly suggest multi-culture families or international students staying in Korea, for the wiser use of their abilities, their easy adaptation to the new world, and the peaceful coexistence.

The purpose of this study is to present the base for activation policy for cost estimation guidelines of e-Learning content development. To achieve this purpose, this study investigates the effectiveness of cost estimation guidelines of e-Learning content development through a survey about executives and employees in the e-Learning industry and analyses them statistically. According to an analysis, companies(which abandoned order because the amount of money (cost) of e-Learning contents ordering is low and suffered a loss after acquiring e-Learning contents project order) have a relatively negative awareness about the effectiveness of cost estimation guidelines of e-Learning contents. On the other hand, contents focused companies have a relatively positive awareness about the effectiveness of cost estimation guidelines of e-Learning contents. In conclusion, this study suggests that government should recommend and enact announce the use of cost estimation criteria(guidelines) of e-Learning content development and provide the institutional tools soon as possible.

As the environment of wireless mobile is developed, the number of users who want to searching the information on the mobile internet is increasing as same as the contents are increasing. However the contents is just offered limited contents which should be charged such as download sounds and images. Users cannot be satisfied with their needs for searching information. The other hands, the reason why cannot achieved the effective comparison with costs is that the costs of development contents is very expensive. So variable contents cannot produced as much as users want. On this papers will introduce the way of producing the mobile contents by low cost. The program 'Mobuilder' will be introduced, which is the program to transfer directly form web contents to mobile contents. And it will propose the guideline to design mobile contents and mobile web will be developed mobile news site by proposed guideline and build the mobile site.

21st Century is getting into Super aging society worldwide basis. Among those population, silver(aged) generation users' physical condition, such as sight, hearing and body, is getting older, especially sight ability which processes 80% of input data, it requires us studying new smartphone GUI designs convergence for the elderly. In light of this social phenomenon, this study suggests smartphone GUI designs convergence guideline for the silver generation through the research of text, icon which are basic elements of smartphone GUI with proper visual attributes. I had inferred UX designs, expert group and evaluation categories from existing papers, related books and designed some displays for the survey. I also offered this guideline with the deep survey of 101 people over 65 years old.

건축시장에서도 지식정보화로 등장한 BIMtleofmf 맞이하게 되었다. BIM(Building Information Modeling)은 전통적인 건축의 2D해석방법을 보다 실물 그대로의 형태로 가상의 디지털 공간에 구현하는 방법이다. 이는 건축시장 전반에 일대 지각변동이 야기될 전망이다. 건축사사무소의 경우 설계 프로세스의 변화, 디자인팀 구성의 변화, 저작권과 관련된 계약의 변화, 건축사의 역할의 변화 등 많은 변화가 대기하고 있는 실정이다. 최근에는 우리 건축시장에도 BIM으로 발주되기 시작하고 있다. 이에 대한 준비가 없이는 많은 혼란과 대가를 치러야 되는 상황으로 몰리고 있는 안타까운 실정이다. 건축은 건축이라는 큰 주제를 가지는 여러 전문집단이 함께 협업(collaboration)하여 이루어 가는 행위들로 볼 수 있다. 여러 관계자간의 상호 밀접한 협업과 분명한 역할 분담이 요구된다. 따라서 이에 대한 대비를 해나가야 한다. 이에 대한 방법으로 국외의 BIM 가이드라인을 조사 분석하고 장단점을 파악하여 국내 건축시장의 전통적이며 지역적 특성을 반영하는 국내 BIM 가이드라인을 만드는 과정에서 조사된 주요 해외 사례를 살펴보고자 한다. 이를 통하여 건축사 여러분들과 함께 고민하고 준비하는 기회를 지면을 통하여 갖고자 한다. 많은 관심과 성원을 기대하며${\cdots}$.

The conditions after exposure to digital mammography and digital breast tomosynthesis were analyzed. The examinations for the ACR phantom were done using manual exposure, not auto exposure, to examine image discrimination and patient dose. As a result, the following results were derived: In the CC exposure, the kVp was 2kVp higher while mAs decreased to 58.6% for the 3D tomography. Such result showed an approximate decrease of 60mAs. At that time, the patients' Average Glandular Dose (AGD) was 1.65mGy in 2D and 1.87mGy in 3D; thus, AGD of 3D was shown to have about 1.13times higher. The result of the manual exposure revealed a reduced mAs of up to 80%; there was no effect in the assessment standard in terms of image discrimination, resulting in more than 10 points. When mAs was reduced to 80% in the manual exposure for ACR phantom, AGD was decreased to 0.66mGy. The diagnostic values of images were maintained and patients dose was reduced in the manual exposure in the AEC condition for 3D. Since the use of 3D has recently increased, using the manual exposure has been recommended in this study to improve the diagnostic value, while, simultaneously reducing patients dose.
