이동 객체에 대한 위치 정보의 획득, 저장, 데이터 모델링 방법과 질의 처리 방법에 관한 다양한 연구가 진행됨에 따라 이동 객체의 위치 정보를 획득, 저장, 관리, 질의 처리가 가능한 이동 객체 데이터 베이스 시스템이 등장하고 있다. 그러나 이동중인 사용자가 자신의 요청을 시스템이 제공하는 복잡한 시공간 질의어로 표현하기는 어렵다. 따라서 이 논문에서는 이동 단말기에서 사용자가 편리하게 질의를 요청하고 현재 또는 과거의 위치를 추적하며 이동 객체들에 대한 모니터링을 하기 위한 사용자 인터페이스를 설계하고 이러한 인터페이스를 구현하기 위한 시스템을 설계한다.

인맥이란 정계, 재계, 학계 따위에서 형성된 사람들의 유대 관계를 뜻한다. 인맥은 거미줄과 같이 서로 뒤엉켜 있고 여러 요인들이 작용하기 때문에 효율적인 인맥 관리를 하기 위해선 많은 시간과 노력이 필요하다. 스마트폰 명함관리 어플리케이션은 모바일 카메라를 이용하여 명함정보를 디지털화 하여 이용하고 있지만 모바일에 정리된 명함의 정보들을 시각화하는 기술은 미흡하다. 따라서 본 논문에서는 명함의 요인들 중 이름, 직급, 회사명, 회사주소, 전화번호, 이메일 주소의 데이터를 이용하여 데이터 시각화 요소를 설계하고 사회연결망 이론을 적용하여 소시오그램 형태로 나타내어 효율적인 인맥 관리가 이루어 질 수 있는 명함관리 시스템 시각화 모형을 설계하였다.

최근 감정노동으로 인해 고충을 겪고 있는 사람들이 늘어가고 있다. 이로 인해 감정노동이 사회적 이슈가 되고 있으며 감정 노동을 해결하기 위해 조직들은 다양한 해결 방법들을 모색하고 시행하고 있다. 감정노동이란 육체가 힘들기 보다는 정신적 스트레스와 상처가 문제이기 때문에 이를 해결하기 위해서 기업들은 심리상담, 심리치료 등의 서비스 제도를 시행하고 있지만 한계가 있다. 업무 특성상 감정 노동에 장시간 노출 되어 고통 받고 있는 조직원들의 상황을 조직 내 커뮤니케이션 빈도와 관계를 분석하고 커뮤니케이션의 핵심역할을 하고 있는 인재들을 소시오그램 형태로 시각적으로 보여주어 조직 발전에 도움을 주는 시스템 시각화 절차와 소시오그램 요소를 설계하였다.

In this paper, we propose a method to design and implement a smart pipeline information management system that can provide visualization information linked to GIS and roadmap based on the construction of precise pipeline buried information. The smart pipeline information management system consists of a positioning device for high-precision pipeline location measurement and surround view image data recording, a database for data storage and management, and a mobile app for remote monitoring and management. It connects surrounding image data and location data with GIS and roadmap. Convenience and accessibility of management can be improved.

Augmented Reality (AR) enables the enhanced realism and interaction by providing the overlaid digital information on the user's view of the physical world. In this paper, we propose an AR-based ship design visualization system for presenting ship 3D model in smart phones or table PCs. The proposed system compute corner points and feature points by contour finding method and harris corner detector, and build a ship-design drawing database. By using SURF algorithm, key feature points are extracted from ship-design drawing image which is obtained by mobile camera. Then ship-design drawing image is recognized by matching the feature points stored in DB and extracted key feature points. 3D ship structures are visualized by overlaying the ship-design drawing image on the smart phone or table PC's screen. Compared to conventional 2D ship-design, proposed system helps to easily understand the structures of the ship and reduce the business design period. Thus, Enhanced competitiveness of business is expected.

The u-GIS national land information providing technology is the technology which maximizes the application of u- GIS data through the national land information platform technique of the next generation web and provides a user with the on-demand national land information in the ubiquitous environment. Recently, as the environment emphasizing the web as a platform 'Web 2.0' emerges, the where 2.0 which is paradigm is diffused in the spatial information area. And the Geo-spatial Web technology develops in a center. Moreover, it is changed to the open platform of the user participation trend. And the consumer of the geo-spatial information is changed to the end-user center from the public institution. The geo-spatial technique is technologically faced with the new challenge. In this paper, we analyze the technical tendency about a paradigm, And we present the u-GIS national land information platform technique, the u-GIS national land information visualization technology, the u-GIS national land information GeoDRM integrative technique, and the u-GIS national land information mobile application technology as the essential elemental technology for overcoming this.

In this paper, we propose a client server based distributed/parallel system to effectively visualize huge geographic data. The system consists of a web-based client GUI program and a distributed/parallel server program which runs on multiple PC clusters. To make the client program run on mobile devices as well as PCs, the graphical user interface has been designed by using JOGL, the java-based OpenGL graphics library, and sending the information about current available memory space and maximum display resolution the server can minimize the amount of tasks. PC clusters used to play the role of the server access requested geographic data from distributed disks, and properly re-sample them, then send the results back to the client. To minimize the latency happened in repeatedly access the distributed stored geography data, cache data structures have been maintained in both every nodes of the server and the client.

In smart work environment, a company provides employees a flexible work environment for tele-working using mobile phone or portable devices. On the other hand, such environment are exposed to the risks which the attacker can intrude into computer systems or leak personal information of smart-workers' and gain a company's sensitive information. To reduce these risks, the security administrator needs to analyze the usage patterns of employees and detect abnormal behaviors by monitoring VPN(Virtual Private Network) access log. This paper proposes a decision support system that can notify the status by using visualization and similarity measure through clustering analysis. On average, 88.7% of abnormal event can be detected by this proposed method. With this proposed system, the security administrator can detect abnormal behaviors of the employees and prevent account theft.
