가상현실 시스템에서 체험자가 현실과 같은 몰입을 느끼기 위해서는 하드웨어를 통한 가상환경 구축과 체험자와의 상호작용이 중요하다. 본 논문에서는 위치 추적 시스템(Motion Tracking System), Wand(3D Mouse) 및 HoloPoint 등 다양한 VR 인터페이스를 통해 체험자의 움직임, 위치, 동작을 인식하고 대형 멀티 디스플레이 시스템을 통해 입체영상을 제공하는 가상환경을 구축하고 체험자가 원하는 정보를 상호작용(Interaction)으로 제공할 수 있는 가상 캠퍼스 안내 시스템을 구현하고자 한다. 가상 캠퍼스 구축은 캠퍼스의 지형, 건물 및 구조물들의 정확한 형상을 얻기 위해 3D 스캐너를 이용하였고 획득된 데이터는 일련의 과정들을 거쳐 3D 모델로 생성된다. 이렇게 생성된 모델을 재배치 및 최적화하기 위해 모델링 소프트웨어를 사용하였다. 구축된 가상 캠퍼스와 위치 추적 시스템 및 Wand의 연동을 위해 VR 프로그래밍 하여 체험자의 움직임 및 동작을 콘텐츠에 그대로 적용시켰다. 여기에 키오스크 유형의 HoloPoint를 이용하여 체험자의 손동작으로 상호작용하는 안내시스템도 구축하였다. 상호작용 가능한 가상캠퍼스 안내 시스템은 가상현실 시스템 구축에 대한 또 다른 방법과 활용 예를 제시함으로써 가상전시관 및 가상체험관 등에 활용될 수 있을 것으로 기대된다.

In this paper, we analyzed the factors influencing the size of Korea Polytechnic as a public vocational education and training institution through analysis of demand, region, industry, and demand with established existing campus and new campus in Korea Polytechnic. By analyzing data on admission, training, and employment for 3 years out of 37 campuses, we have sampled 5 campuses by type of Korea Polytechnic, fused with the results derived from the literature analysis and in-depth analysis results, so that the regional campus will play a leading role and the direction of development. The selection of five campuses by type is a precedent study to analyze 37 campuses in the future. As a result of the study, the demand analysis through objective indicators such as the number of high school graduates, the number of employed persons, the presence of nearby industrial complexes, and policy variables is very important and reflects the reality well. Therefore, it is necessary to analyze the demand through the objective indicators in decision making related to the new campus at the pre-analysis stage. In addition to the general data proposed in this paper, that is, common variables in all regions, it is important to consider the factors that can reflect local demand characteristics when considering specific locations.

본 논문에서는 관련 지식이 없더라도 취약한 비밀번호를 사용하는 AP(Access Point)를 빠르고 편하게 점검할 수 있는 소형 해킹 장치를 제안한다. 터치 디스플레이를 이용한 입출력 장치의 통합으로 휴대성을 극대화시켰다. 필요한 정보를 특정하여 출력하고, 숫자 입력만으로 프로그램을 제어하며, AP의 보안 프로토콜 유형을 자동으로 인식하여 그에 맞는 공격을 시도하는 등의 사용자의 편의성을 고려한 프로그램 설계로 입력장치의 제한으로 인해 생길 수 있는 불편함을 해소하였다.

Recently, Internet (IoT) and big data have been utilized in various fields such as medical, military and sports. Korea Nazarene University is a rehabilitation-welfare university with about 300 students with disabilities. This paper proposes a smart campus that provides the optimal path for the calculation of the route and risk avoidance using the BLE beacon and the 3-axis acceleration sensor when the students with disabilities move in the campus both indoors and outdoors. So we can manage the big data and sensor-based IoT technology for students with disabilities.

The purpose of this study is to evaluate human thermal comfort by spatial structure and to explore solutions to improve the thermal environment of a small urban space. The study site was Korea University campus. Thermal conditions were measured to evaluate the quality of the thermal environment in each type of space within the study site. Micrometeorology measurements, analysis of space characteristics for using fish-eye lens photography, and thermal comfort modeling through the use of collected meteorological data, such as temperature and humidity, were performed. Results showed that the level of thermal comfort for humans differs depending on the types of space within the study site. Thermal comfort is better in open spaces than enclosed in the aspect of radiative mean temperature, Predicted Mean Vote(PMV), and Physiologically Equivalent Temperature(PET). This fact is probably due to shadows or buildings or trees that may block solar radiation. Thus, it is necessary to consider the spatial arrangements of buildings and trees to enhance openness and ventilation in the space. Paving materials and exterior building materials should also be selected to lower the radiant temperature. Given these results, a quantitative evaluation on human thermal comfort could propose a way to plan user comfortable small urban spaces. Study methods used and results provided in the study can promote a better way for urban space planning direction to improve environmental quality.

The Ubiquitous Sensor Network, a new computing paradigm, is a core technology of ubiquitous computing for context-awareness monitoring system using sensor networks. Recently, ubiquitous campus has been developed to build ubiquitous computing environments in many universities. In this paper, I propose the development of context-awareness monitoring system, to acquire the context information through various sensors and provide the campus information and safety services for students with disabilities using mobile devices. Ubiquitous sensor system based on u-campus technology for students with disabilities can especially be used to provide customized information.

The impervious ratio was frequently employed as a fundamental attribute will be used as a proxy of the total environmental burden in the urban area since it may contribute as much or more on a cumulative basis to the overall environmental condition. This research proposes a comparative evaluation framework in a more objective and Quantitative way for an impervious ratio in the university campus, using the Google Earth. Two university campuses (Kyungpook National University: KNU, Hong Kong University: HKUJ were selected as survey objectives in order to evaluate the potential of Google Earth in monitoring impervious conditions in the campus. The 61cm resolution of Quickbird data combined with digital map realistically identified the major type of impervious surface such as road, building and parking lots in the study area by large scale spatial precision. The impervious zones with persistently high road density and parking space were specifically identified over the KNU campus while the HKC campus was intensively covered by tree, resulting in almost twice (31%). as compared to KNU (18.4%), The methods of characterizing impervious surface used in this study are easily replicable using data that are primarily publicly available, and therefore the collection of impervious coverage data via Google Earth is, therefore, proposed as a practical alternative.

The gate of university can be the first impression of the University itself and most important advertising structure which is more than just a structure that people pass by. It can also be the medium that connects the outside with the inside of the campus. Therefore, many universities are willing to have a unique and symbolic gate of their own. Recently, university representatives have become interested in arranging external areas of the campus. At this respect, studying and researching university gates and surroundings facilities must be realized. We visited 104 different universities gates to research and survey people about what they think of the internal and external individuality of each gate. According to these researches we established a full data base of 24 types of classifications, 5 characteristic forms of each shapes, 8 forms of the symbolic characteristics of university gates and 10 surroundings facilities of the university gates.
