There has been an enormous increase not only in the international economic exchanges but also in the cultural exchanges. However, studies to settle the cultural differences have been studied a lot with in economic and business partial but research of eliminating cultural differences for travelers has not been studied. Therefore, in this study, we tried to develop the service design to eliminate the cultural differences. To set the spatial range, we choose airport which can be the hub and the door of the travelers at the same time. Moreover, we tried to understand the meaning of communication and sharing to resolve differences in culture through literature studies. Further, we analyzed the airport application and examples of Wi-Fi linked services, so can be applied to the proposal. Travelers share the cultural differences by themselves; through the Wi-Fi service in the airport, and the existing airport application. We expect to be able to resolve the cultural differences between nations and develop not only their prosperity but also the national image by this service.

This study aims to develop communication devices and interfaces to address the communication needs of the hearing impaired. Through three FGI (Focused Group Interview)s with deaf persons and sign-language interpreters, we studied the communication methods, devices, and needs of the deaf. On the basis of our analysis, we propose a communication framework to improve their means of communication with normal or other deaf persons. We have designed a communication system that is based on the proposed framework: this system suggests functions for remote sign-language interpretation services for conversations in close-range and over the phone. Details are presented regarding the design of interfaces for video calls, text messages, and digital memos, addressing the conversation patterns of the deaf. The system includes hardware form factors for video phones that facilitate sign language conversations and also mitigate other auditory problems in daily life, such as problems with door bells. The design concept has been verified through a test with six deaf users.

This paper describes a visual programming tool which provides novice programmer as well expert with the abilites to capture real physical world of problem domain and to manipulate it user-friendly using icons and symbols. Therefore, novice can understand object-oriented features of C＋＋ incrementally and construct classes easily. For this, we introduce some visual metaphors which are displayed as tables. The tables can not only represent objects and classes, but also be considered themselves as icons. We have named these tables as table-icons. Three levels of table-icons(i.e., Super Table-Icons, Intermediate Table-Icons and Detailed Table-Icons) are proposed to follow up appropriate evolution of object-oriented concepts. Table-icons are not simple pictographs but are activated and expanded to table forms. And then, developer can inset necessary entities into table body and delete useless entities from it. These table-icons are applied to a diagramming technique, C＋＋gram［18］, which is suggested for designing and implementing C＋＋ programs.

오늘날 멀티미디어 정보의 양이 매우 빠른 속도로 증가함에 따라 멀티미디어 데이타베이스에 대한 효율적인 관리는 더욱 중요한 의미를 가지게 되었다. 게다가 영상과 같은 비 문자형태의 데이타에 대한 사용자들의 내용기반 검색욕구 증가로 인해 비디오 인덱싱에 대한 관심은 더욱 고조되고 있다. 따라서 본 논문에서는 우선적으로 분할된 샷 경계면에서 추출된 대표 프레임과 정지 영상 데이타베이스로부터 유사 영상과 유사 대표 프레임을 검색할 수 있는 환경을 제공한다. 우선적으로 영상에 의한 질의는 기존에 주로 사용되어온 색상 히스토그램방식을 탈피하여 본 논문에서 제안하는 CS와 GS방식을 이용하여 색상 및 방향성 정보도 고려하도록 설계하였다. 또한 얼굴에 의한 질의는 대표 프레임으로부터 얼굴 영역을 추출해 내고 얼굴의 경계선 값 및 쌍 직교 웨이블릿 변환에 의해 얻어진 2개의 특징값을 이용하여 유사 인물이 포함된 대표 프레임을 검색해 내도록 설계하였다. Abstract There is a rapid increase in the use of digital video information in recent years, it becomes more important to manage multimedia databases efficiently. There is a big concern about video indexing because users require content-based image retrieval. In this paper, we first propose query-by-image system environment which allows to retrieve similar images from the chosen representative frames or images from the image databases. This algorithm considers not only the discretized color histogram but also the proposed directional information called CS & GS method. Finally, we designe another query environment using query-by-face. In this system , user selects a people in the representative frame browser and then system extracts a face region from that frame. After that system retrieves similar representative frames using 2 features, edge information and biorthogonal wavelet transform.

In Unicode, two types of Hangul encoding schemes are currently in use, namely, the "precomposed modern Hangul syllables" model and the "conjoining Hangul characters" model. The current Unicode Hangul conjoining rules allow a precomposed Hangul syllable to be a member of a syllable which includes conjoining Hangul characters; this has resulted in a number of different Hangul encoding implementations. This unfortunate problem stems from an incomplete understanding of the Hangul writing system when the normalization and encoding schemes were originally designed. In particular, the extended use of old Hangul was not taken into consideration. As a result, there are different ways to represent Hangul syllables, and this cause problem in the processing of Hangul text, for instance in searching, comparison and sorting functions. In this paper, we discuss the problems with the normalization of current Hangul encodings, and suggest a single efficient rule to correctly process the Hangul encoding in Unicode.

Starting the popularity of Korean dramas exported to China in 1996, the Korean wave started around the world market. Afterwards, as the Korean culture itself as well as dramas rapidly emerged as contents of the Korean market, the foreign direct sale consumers who want to buy Korean goods directly online are increasing at an alarming rate. This study each selected 4 domestic shopping malls and 4 foreign famous shopping malls which were conducting a global marketing currently and compared/researched them in the design aspect in order to apprehend if domestic online shopping malls were properly meeting the consumer environment of the foreign market. As a result, it was revealed that domestic online shopping malls conducting the global marketing could not fully understand the internet environment by countries and were going through a limit of the information delivery by SMS, and could not use the visual signs actively which were useful to the meaning delivery. Accordingly, this thesis suggested a plan to actively utilize the variable element considering various screens to the design, plan to efficiently design the text for solving the language problem by countries, and plan to design using the developing IT technology as a solution to those problems.

Recently, the importance of cultural design has been increasing due to the globalization. However the cultural design is mainly focusing on the shape or color stereotype of different cultures, ignoring another important aspects of cultural design: the way of peoples' interacting with product. The study aims to develop usability test program for cultural user-interface design that operates in the world wide web. The study begins with discussing the nature of culture through defining culture and reviewing the depth and variables of culture. Based on the findings the structure of the usability testing program on the WWW design methods is identified. The usability testing program on the WWW comprises of five different modules: module for identifying users' demographic characteristics, module for cultural variables, module for population stereotype, module for usability testing, and module for data storage and analysis. Finally findings are summarized and further research prospects are outlined.

According to the development and expansion of software and hardware about recent information technologies(IT), disabled persons in using IT seem to feel more information gap. Devices for IT are important tools for users including disabled persons to communicate with each other and get information. Although the Korea faces ageing society rapidly, products for disabled persons are seldom shown in time for use. As getting older especially, one of the body function disorders is visual disturbance. There are tools, braille lettering, for disabled persons with visual disturbance to communicate or get information from book. Compared to general books, however, braille lettering book is lack of including all of information of our society. Therefore, in this paper, we implement and show an embedded system for disabled person with visual disturbance to get information by scanning text, extγacting characters and converting the text to speech automatically.
