공항은 다양한 시설들이 혼재되어 있는 복합 공간으로 원하는 장소로 이동하기 위해서는 지도나 표지판뿐만 아니라 유·무인 안내 서비스를 이용하는 것이 필수적이다. 그러나 이러한 시설 안내 서비스는 이용객의 대다수를 차지하는 비장애인을 기준으로 설계되어 있는 것이 대부분이며, 특히 청각장애인은 음성 언어인 한국어를 통한 의사소통이 어려워 이러한 안내 서비스의 사각 지대에 놓여있다고 볼 수 있다. 본 논문에서는 청각장애인을 대상으로 공항 내 시설 위치 안내 서비스를 제공하는 키오스크를 구현하기 위해 마커리스(makerless) 한국 수어 인식 기술을 적용하는 방법을 제안한다. 기존의 알고리즘들이 수어를 인식하기 위해 사용자의 신체에 마커(marker)를 부착하거나 사용에 제약이 있는 깊이, 자기장 센서 등을 활용한 데 반해, 특징점 기반의 인식 기술은 별도의 마커 없이 RGB 영상만을 활용하여 수어를 인식하기 때문에 사용자의 편의성을 극대화할 수 있는 방법이다. 영상 기반의 마커리스 수어 인식 기술을 위치 안내 키오스크에 적용함으로써 청각장애인이 다른 사람의 도움 없이 공항 시설을 쉽고 안전하게 이용할 수 있도록 지원할 수 있으며, 나아가 배리어프리 (barrier-free) 공항을 구현하는 데에 큰 도움이 될 수 있을 것으로 기대된다.

To improve medical service and customers' satisfaction by reducing actual waiting time for medical inspection by personalized examination guidance contents (PEGC) linked with medical information system (MIS). The suggested PEGC was completed with preparing transmission for data and PEGC by using transmission control protocol internet protocol (TCP/IP) which can be built up creditable data transmission service. When patient signal event appeared in MIS while the communication was in standby, the ID and data of the customer were shown as text and image on monitors in waiting room. Guiding inspections, steps of examination, and undressing information extracted from the PEGC was also shown to the appropriate patient. After installation of the suggested PEGC, we rechecked satisfaction rates of 60 customers who visited the hospital with a same method as initial survey. The results of this study suggest that 3.6 point of waiting time satisfaction index were improved, after installation of the suggested PEGC, as 4.6 point.

As a part of public design, private signboard should be designed to help convenience of people with the consideration of urban landscape simultaneously; however, the lack of legislated design regulations and ignorance of managing entities have resulted in uncontrolled installation of private signboards, ruining city view and causing confusion in delivering information. To appease this problem, each provincial city including Seoul is carrying out an improvement project based on its own sign management guideline. Therefore, it is timely needed to study the design satisfaction on the changed (or changing) private boards from the viewpoints of information delivery and visual environment. In this study, we investigated the design satisfaction of private signboards in Daejeon city (where very recently the improvement project has been undergoing based on its design guideline) in terms of visual factors, information delivery, and city landscape. We note that our study has its own significance to provide an empirical research on the design satisfaction of private signboards, which shows that people are mostly satisfied with the new design from aspects of visual factors, information delivery, and city landscape.

Road guide sign is one of important traffic facility, which guides a driver a direction to go. A road is being newly built and/or an existing road can be temporarily closed very often at metropolitan area. Such information has to be linked to a road guide sign and to be updated in time. Otherwise, it might cause not only confusion to a driver but also traffic accident and/or traffic congestion. However, road guide signs are not properly managed at this time since the amounts of information are huge and they are being managed through paper maps manually. A decision-making framework has been developed to manage a variety of information of road guide signs based on the concept of GIS(Geographic Information Systems). Especially, it is designed on the fact that the existing national digital base maps under the NGIS(National Geographic Information Systems) program can be utilized. This framework has several functions such as the manipulation of statistics, landmark linkages along the selected traffic corridor and automatic design of signboard's content. This system is applied to the Kangnam district in Seoul Metropolitan area (SMA) for a case study.

As concerns about users' privacy infringement on Online Behavioral Advertising(OBA) increase, regulators are taking measures such as drawing up guidelines for OBAs, and websites provide OBA guidance in compliance with such guidelines. As a result of reviewing the status of providing OBA guidance on websites, access to OBA guidance pages was rather complicated. In order to analyze the issue from the UI/UX perspective, following the "Guidelines for Privacy in Online Behavioral Advertising" applied to all types of OBA transmitted on websites, this study aims to structuralize a navigation of page movement from two starting points, 1) Main Page, 2) The page where OBA is delivered, to OBA guidance pages. Also, with understanding the problems found in the access and navigation of OBA guidance pages by analyzing features found during the page navigation, such as hyperlinks containing keywords, and movement pages.

This research is to analyze the status of menu guides provided to inpatients in Korean hospitals, analyze the problem of delivering information, and propose improvement plans through information visualization as a part of improving service for inpatients. The nutrition department in hospitals were directly visited, data were collected, and the types and contents of menu guides were analyzed. Then, problems were found by focusing on whether there is an effective delivery of information, in terms of information visualization aspects. The menu provided to inpatients in Korean hospitals are divided into general, optional, and therapeutic menu depending on patients' conditions, and the menu guide is largely divided into a general guide and optional guide. The information covers menu, origin of ingredients, guide, withdrawal time, etc. However, there is no categorization according to the contents or importance of information, thus creating inefficient problems for patients to acquire information. The problem of menu guides is that they do not deliver information properly due to disorganized information. In order to improve this, information should be categorized and visualized according to its contents and importance for enhancing readability, which will then be able to provide menu guides that can deliver information more efficiently to patients.

디지털 시대가 도래하면서 지식 또는 정보의 신속하고 편리하며 효과적인 전달 수단을 강구하기 위한 기술이 빠른 속도로 발전하고 있다. 컴퓨터 기술과 네트워크 기술 등의 발전으로 사람의 업무 영역을 컴퓨터가 대신하는 분야는 크게 증가하고 있는데, 대표적인 것 중의 하나가 무인안내 시스템 (Information KIOSK System) 이다. 무인안내시스템은 사람을 대신해서 또는 사람이 할 수 없었던 정보의 전달을 멀티미디어를 이용하여 간단한 조작만으로 손쉽게 각종 정보를 제공하는 컴퓨터 시스템으로, 시간과 장소의 구애를 받지 않고 24시간 신속하고 정확한 정보 제공이 가능하며, 새로운 정보를 쉽고 빠르게 제공할 수 있고 운영 비용이 저렴하기 때문에 개발 초기에 시스템을 구축하는 비용이 많이 소요되고 아직 많은 사람들이 컴퓨터에 친숙하지 못함에도 활용하는 사례가 크게 확대되고 있다. 특히 인터넷의 발전으로 더욱 빠른 속도로 유인안내소를 대치하고 있다. 무인안내시스템 개발에 필요한 기술 분야와 관련된 많은 연구논문과 기술문서 등이 존재한다. 그러나 무인안내시스템을 성공적으로 개발하는 데에는 기술적인 면 이외에 성공적인 개발을 위해 고려해야 할 중요한 요소들이 많이 있지만, 공학적인 측면의 일반적인 내용을 언급한 문서들만이 존재하며 이와 관련된 현실적이고 체계적인 문서는 없는 실정이다. 본 논문에서는 성공적인 무인안내시스템의 개발을 위하여 기술적인 측면 이외의 대규모의 무인안내시스템의 개발에 필요한 제반 사항을 살펴보았다.

When a fire occurs in a large-scale or complicated facility there is a possibility of large-scale loss of life if there is no information on the location of fire and the location of emergency exits for people to take shelter. Consequently, the fire or disaster prevention system and the shelter course guidance system that optimally guides the shelter course are necessary to reduce the loss of life. This paper proposes a shelter course guidance system using a sensor network to reduce the loss of life in a building where a fire occurs. The experimental result of this research shows that the shelter course guidance system provides the optimum shelter course to people in infrastructure when a fire occurs.

Urban railway are the most widely used means of transportation in the metropolitan area. It is difficult to draw out problems through the quantitative analysis technique because most of the research results show that most of the guide signs are installed with many or few guide signs. In this study, we propose a method to evaluate the information load and proper installation location at the main decision point in the transfer passageway for Suseo Station by applying Positive Guidance. As a result of analyzing the information load using this technique, it is suggested that the necessary information should be provided centered on the copper node because it provides confusion of the users by providing the same information in the transfer line. It is necessary to obtain guidance on how to remove the sign (advertising, high ceilings, etc). The study will be regarded as a key for the basis and placement of the guidelines for determining the appropriateness of the in the future urban railway station sign guide.
