Multiple roadmap DB providers are already available in these days, and try to reduce unknown roads in their own roadmaps. However, cooperation models or Win-Win approaches between roadmap providers are not considered yet. Thus, In this paper, We proposed a cloud-oriented real-time roadmap generation and update method between heterogeneous navigation systems for unknown roads. With the proposed method, the roadmap DB providers update the own roadmap DB for navigation systems in real time. Also, they can provide the complete roadmap without unknown roads to users instantly. Therefore, the proposed method can reduce the costs of an actual traveling test and the maintenance for the roadmap DB provides. Thus, the cloud-oriented roadmap generation method can more efficiently update the unknown road information.

본 프로젝트는 날씨와 GPS 위치정보를 이용해 사용자들에게 자전거 라이딩을 하기 전에 현재 및 예상날씨정보, 로드맵을 제공하는 자전거 애플리케이션이다. GPS 위치정보를 활용한 네비게이션 기능으로 사용자가 자전거 라이딩을 할 때 현재위치, 목적지 경로, 주행 시간, 주행 경로와 같은 유용한 정보들을 제공해주는 프로젝트이다. 일반 자전거 어플리케이션은 자전거 속력, 현재 날씨 등과 같이 간단한 정보들을 제공해 주는 것에 반해 본 프로젝트는 자전거 라이딩 사용자들에게 날씨뿐만 아니라 로드맵을 제공하여 본인의 위치, 경로, 등을 제공하며 길 찾기, 자전거 라이딩 정보를 제공함으로써 사용자들이 자전거를 좀 더 효율적으로 탈 수 있게끔 자전거 어플리케이션을 개발하였다.

Recent clinical studies have shown that computer navigation for total knee arthroplasty (TKA) provides improved component alignment accuracy. However, femoral stress fracture after computernavigated TKA have been reported due to the pin hole and we hypothesized that osteoporosis would be one of the key factors in pin hole fracture after computer-navigated TKA. We investigated the von-Mises stress around the femoral pin-hole for different elastic modulli and ultimate stresses and four different pin penetration modes to understand the aging effect on femoral stress fracture risk after computer-navigated TKA by finite element analysis. In this study, aging effect was shown to increase the femoral stress fracture risk for all pin penetration modes. Especially, aging effect was shown dramatically in the transcortical pin penetration mode.

Recently enterprises, which posses high-speed internet and high-performance computers, have tried to use MIS(management information systems) to deal with whole task efficiently. This study considers design of menu navigation using SNA(social network analysis) to be able to move between menus of MIS efficiently. We extracted the important menu lists through the high SNA measures such as degree centrality, betweenness centrality and closeness centrality, developed web-pages and investigated its application. The findings will be used for design of web menu navigation and guide of strategic planning for MIS.

This study examined how the fire evacuation induction service system using a smartphone navigation application in the event of a fire affects the fire evacuation time, and the following conclusions were drawn. 1. The evacuation time was reduced by 22 seconds when the navigation application was used in computer scenario simulation. Even in the demonstration simulation, the evacuation time was reduced by 40 seconds when the navigation application was used. This indicates that the navigation application is effective in shortening the evacuation time in case of fire. 2. As a result of the demonstration scenario simulation, the time until the end of evacuation was 39 seconds faster in the case of evacuation guidance than in the case where it was not conducted. 3. No bottlenecks occurred in the evacuation route during the demonstration scenario simulation. As a result, there was a difference in the time required to complete the evacuation between the computer scenario simulation and the demonstration scenario simulation.

Two-dimensional image processing method and tools Rigi then developed a report prepared by a variety of video and three-dimensional images are increasing demands for navigation. The hard part to experience in the real world experience in the virtual environment, and has the purpose to take advantage of. This is a system that provides a simple 3D background, but everyday actions that can control the system with the needs of an instinctive interface technology means. The purpose of this study a variety of human behavior using the Kinect device in action close to the three-dimensional technology to develop a new navigation control is Kinect Holography and 3D images using the input data so that you have the linkage is to design the system.

We designed and implemented an automatic update system of 네비게이션 contents. Currently car users are updating map contents of their 네비게이션 system by using SD memory card. In the implemented system, map contents are downloaded via WI-FI internet access while served in a gas station. To prevent free rider at gas stations, we adopted authentication mechanism based on MAC address.

This study is intended to verify the efficiency of the information system by using the navigation application in case of fire. In the demonstration scenario simulation, it was assumed that a fire occurred 6th floor in Korea Institute of Industrial Design Promotion located in C city, K province. Eighty juniors students from K University's department of paramedics of science participated. As a result of the experiment, the demonstration simulation using the navigation application showed that the evacuation time was faster than the case of evacuation guidance in a fire situation. The need for a fire prevention system and fire prevention awareness before and after the implementation of the demonstration scenario simulation increased the need for a fire prevention system and fire prevention awareness score after the experiment.

우리가 많든 적든 관련이 있는 거의 대부분의 일들이 컴퓨터 없인 제대로 완성될 수 없는 것처럼 컴퓨터는 우리 일상에서 뗄레야 뗄 수 없는 필수품이 되었다. 불과 몇 년 전까지만 해도 SF 영화에서나 보던, 지하철에서 혹은 버스 안에서도 게임을 하거나 영화를 보는 모습이 이제 그리 낯설지 않으니 말이다. 데스크탑에 저장해 놓은 어마어마한 용량의 자료들을 큰 외장하드에 넣고 옮겨 다니는, 혹은 급히 필요한 정보를 찾지 못해 전전긍긍하는 그런 수고는 더 이상 필요 없다. 일반 운전자들에게는 물론이거니와 주 5일제가 시행되고 자가운전자들이 늘어나면서 주말을 이용해 여행을 다니는 사람들이 늘어나며 더욱 유용하게 활용하고 있는 네비게이션의 경우, 단순 길 안내의 기능 뿐만 아니라 영화나 T V를 보고, 음악을 듣고, 개인P D A로도 활용하는 등 다양한 기능이 요구되고 있다.
