In our modern society, the utilization of the advanced drone which is capable of performing variety of tasks has been gradually increasing. In this paper, we present an application, similar to the prototype "Skycall" that had been introduced in the MIT Senseable City. To assess this concept, we have implemented a prototype of drone-based pedestrian navigation depending on the Android smartphone. Our system is not only able to guide the user in a very complicated place, where buildings are compacted, but also to block unauthorized visitors from accessing the facilities. And we discuss some problems we found and suggest the direction to address them.

Recently, the university environment has been changed faster than before. It has based on university environment and IT infrastructure. Especially, most of local university has devised development plan such as improving the image and competitive power of campus. Digital, Electronic and Mobile Campus has increased the importance as people realize that the use of technology can improve the learning process. U-Campus of latest IT Technology need a service environment of which the practical use is possible through IT analysis of the members. For example u-campus setup of mobile offers the convenience to the members. We expected thing to use much, even though actual condition investigation about IT environment of the user is insufficient. The inconvenience of mobile could not be activated to the service for proactive use. The importance became the result about u-campus service setup of a company and university center. This service environment cannot offer specific information of center members for which the service implements. In this paper, we studied about members centralized u-campus model through u-recruit, campus information mobile service on university.

Recently, indoor locating using beacon has gained much attention as an indoor locating technology. This technology has been used for various indoor LBS(location-based services). However, there is a lack of research on LBS service specialized in university yet. In this paper, we designed and implemented a smart LBS system using beacon for campus and class guide in the university. This system provides for campus and class guide services based on the current specific location in the campus, This system can be improved as more precise becon technology is developed.

As the complexity of urban growth out of people with disabilities are subject to many restrictions. In particular, visually impaired people are not allowed to perceive objects as well as objects around the environment, it suffers from a number of outdoor activities to environmental challenges. But the outdoors environment of the current domestic reality is lacking a lot of facilities to assist the activities of people with disabilities, including the visually impaired. In this paper, we propose a navigation system to help the visually impaired in outdoor activities. The proposed system was applied to test the Jeungpyeong campus of Korea National University of Transportation for the exam.

Sanbangsan and Yongmuri Beach as geosites are very wide areas, and tourists have accessed them via various courses; hence the need to double the number of geosite signs and disperse them at each point. The signs should read "Sanbangsan lava dome," "Yongmuri tuff ring," and "Relationship between the Sanbangsan lava dome and Yongmuri tuff ring." The contents of the sign should be systemic, simple, and clear because tourists have to read it in a short time. The viewpoint of the research area can be largely divided into Sanbangsan View, Yongmuri Beach View, Sanbangsan, and Yongmuri Beach View. Three of each viewpoint (total of 9 viewpoints) can be placed. In the geosite of Sanbangsan and Yongmuri Beach are 5 sub-theme views including the boundary sheet of Sanbangsan and Yongmuri tuff ring, xenolith basalt, marine pothole, tafoni, and crossed sedimentary layer. These sub-theme views are important in understating not only the geosite but the overall geopark as well, so they should be developed and utilized aggressively.

현재 대규모 실내공간이 증가하고 있고, 이에 따른 화재 등의 사고가 발생함에 따라 화재대피시스템과 같은 실시간 실내 응용에 대한 관심이 증대되고 있다. 그러나 학문적 연구 또는 상업용 시스템에서 사용되는 화재모델이내 보행자 모델은 대부분 2D 기반의 CAD와 같은 파일구조를 기반으로 하고 있으며 가상데이터를 이용한 시뮬레이션에 초점을 두고 있다. 따라서 이들을 실내 센서 등을 이용한 실시간 시스템으로 구축하기 위해서는 몇 가지 문제점들이 해결되어야 한다. 우선, 실내공간의 의미 있는 관계정보를 포함하는 위상적인 3D 모델이 필요하다. 또한, 실내 센서들에 의해 감지된 보행자의 이동을 저장하고, 저장된 데이터를 이용하여 실시간 안내를 위해서는 실내데이터 구축에 공간 DBMS를 이용해야 한다. 본 연구에서는 실내보행자 모델에서 두 가지 개선점을 제시하고자 한다. 첫째는, 간단한 3D 실내 모델구축과 공간 DBMS와 연계된 보행자 시뮬레이터를 구현하는 과정을 제시한다. 둘째는, 보행자의 가시성(visibility)에 대한 영향이 반영된, 개선된 floor field 모델을 제안한다. 이와 같은 과정을 캠퍼스 건물에 적용하고 시뮬레이션을 수행하는 과정을 예시하였다.

This study aims to reveal path selection strategies and individual differences in a navigation task. Two experiments were presented that studied human route planning performance as well as the cognitive strategies and processes involved. For the outdoor task, university students were asked to select a route based on the instruction, i.e. to find the best route from the campus main gate to the Education Building for conference visitors by locating eight signposts. Results indicate (1) that locations of signposts were selected preferably at decision points where the traveler needs to make a choice and starting/ending points of the navigation task and (2) a variety of route planning strategies considering efficiency goal (e.g., the shortest path), environmental characteristics (e.g., fewest turns), and aesthetic purpose (e.g., most scenic) were used. It is notable that some participants took into account more than one path by locating one or two signposts on an alternative route while others preferred a linear route connecting signposts between the start point and the destination. Prior to the main experiment, the same participants were asked to complete the same task inside the classroom to investigate changes in strategies between two tasks. Participants often tend to place signposts at more regular intervals for the indoor navigation task than the same task conducted outside.

This paper presents a model of e-learning based on ubiquitous computing configuration. First of all, we survey the advanced e-learning systems for foreign and domestic universities. Next we propose the optimal e-learning model based on ubiquitous computing configuration. The proposed e-learning model as following. we propose the e-learning system's hardware and software configurations, that are server and networking systems. Also, we construct the proposed e-learning systems's services. There are attendance and absence service, class management service, common knowledge service, score processing service, facilities management service, personal management service, personal authorization issue management service, campus guide service, lecture-hall management service. Then we propose the laboratory equipment management service, experimental materials management service etc. The proposed model of e-learning based on ubiquitous computing configuration will be able to contribute to the next generation university educational paradigm.
