As the augmented reality market has rapidly grown in recent years, various platform interfaces have emerged. In addition, it provides recommended travel information for each user based on a smartphone. Based on the recommended travel information, it provides the information of a tour path. Even though it is implemented in mobile devices and does not have continuous communication with servers, it needs new technologies that can provide additional entertainment services such as cultural and historical sites in corresponding regions while still providing guides depending on user movements

소비자의 욕구와 개성화, 그리고 시장경쟁력에서 생산체제가 변화되면서 기업들의 물류환경여건도 변화를 가져와 물류가 기업들에게 당면한 주요 과제가 되었다. 사회 간접자본의 부족으로 인한 도로, 항만 등의 정체현상이 심화되고 3D업종에 속하는 물류부문은 더욱 인력난을 겪게 되면서 물류비상승이라는 부담을 안게 되었다. 그리고, 컴퓨터, 정보통신기술 등과 같은 첨단의 기술혁신이 이루어 집에 따라 컴퓨터 및 각종 기기들의 연결이 가능해지면서 물류정보시스템 구축이 활발하게 이루어져 가고 있다. 그러나, 이러한 현실에도 불구하고 기업들은 이에 대한 효율적인 대처 방안을 마련하지 못하고 물류에 대한 인식조차 못하고 있거나 잘못 이해하고 있는 실정이다. 본 논문은 이러한 문제점을 인식하여 물류정보시스템의 활용수준과 물류활동 연계 그리고 물류전략에 대한 이론을 정립하고 이를 근거하여 나라 기업률이 물류를 어떻게 인식하고 있는가를 물류정보시스템의 활용수준, 물류활동연계, 물류전략 등의 변수를 도입, 측정하여 봄으로써 우리나라 기업의 물류에 대한 문제점들을 규명하고 앞으로 물류의 능률적인 실시를 위한 올바른 방향을 제시하는데 그 목적을 두고 있다. 실종분석 결과 물류성과에 대한 물류정보시스템 활용수준과 물류연계수준은 물류성과에 영향을 미치는 것으로 나타났다. 그리고, 물류 기능별 정보시스템 활용수준과 물류차별화 전략이 물류성과에 상호작용 효과를 보이는 지를 알아본 결과 상호작용효과가 있는 것으로 나타났다.

스마트폰의 사용이 생활에 필수적인 요소가 되었다. 스마트폰 특징의 가장 핵심적인 부분이 다양한 콘텐츠를 사용자의 취향에 맞게 선택 할 수 있다는 점이기에 스마트폰의 콘텐츠 시장 또한 빠르게 커지고 있다. 오픈 마켓인 안드로이드의 특성 상 누구나 어플리케이션을 만들어 원하는 곳에 배포할 수 있고 어플리케이션을 다운받을 수 있는 소스도 한정되어 있지 않기 때문에 스마트폰 보안을 위협하는 악의적인 어플리케이션에 노출되기 쉽다. 개인적인 정보가 저장되어 있는 핸드폰의 특징 상 악성코드에 노출 될 경우 전화번호부 유출로 인한 인한 스팸이나 피싱에서 크게는 금융정보 유출까지, 입을 수 있는 피해가 크다. 이를 방지하기 위해 클라우드 컴퓨팅을 이용해 단계적으로 악의적인 어플리케이션을 걸러 내고 클라우드 서버에 어플리케이션 실행 환경을 제공함으로써 사용자의 기기를 안전하게 보호 할 수 있는 시스템을 제안한다.

We researched economic efficiency and possibility of game portal service based PDA/Smart phone by popularize of next generation portable internet WiBro. PDA/Smart phone are difficult to equal level content service with PC, because of it has low CPU and memory than PC. This paper are implemented paper of integrated server of Cable or Wireless for WiBro contents. In this research, we implemented and show test result of CP killer contents in PDA. It can apply to WiBro portable internet and has required many functions in integrated server for cable or wireless. CP Killer contents for WiBro portable internet is developed by PC server base on Window XP. It can accept next generation wireless LAN, portable internet and ubiquitous issues. We expect activation of commercial use that WiBro contents and server trading.

The mobile advertisement has varied on lifestyle of people, who live aninformation-oriented society with portable equipment such as web phone and PDA(Personal Digital Assistant). Also, the advertising has expended mobile techniques and its application field unpredictably. The intrinsic characteristic of misdistribution, reach, and convenience in mobile advertisement add up the capacity of a location, information and individualize. This market condition leads the basic audio focused formal mobile advertisement to the new mobile Internet environment with an additional able of data communication. Moreover, the type of SMS (Short Message Service), Graphic, Wep Push, and ridchmedia, which based on music, basic graphic, voice, and letters transfer by mobile terminal and the mobile character is present inevitably correlation with pixel art and animation in 2D(Two Dimensions) techniques. Thus, this research appoints the importance and its role of mobile advertisement that is core of the business marketing in new media era. To activate mobile market, the mobile companies classify the characteristic of consumers with developed commercial use of mobile character and research their behavior to meet optimal mobile character in business.

Recently, the expert call center solution has become the center of interest, since finance and tele-marketing system, which is focused on a communication industry, have been increasing, Specially, the call center market is growing up with a supporting Caller-ID for a cellular phone in Korea, In the present, although large size companies are developing expensive solutions and instruments to service only for the big companies, there little solutions for SOHO markets, Therefore, in this paper we have shown a design and an implementation of a CTI system which is capable of in/outbound call processing by using CTI, and providing stable services by linking the customer's DB. And these functionalities have become possible by integrating functions of PBX and the computer control of the PBX. First, we have constructed call flows and analyzed packets for the standard communication through the PBX in call. Then, we have designed and implemented a middleware which linked a call between a client and a customer. Finally, we have constructed a database module for applying the CRM technology to the management of customer's contents.

Visual Reality technology is becoming more and more interesting as it attracts people's interest. VR technology is used in various markets such as games, animation, and education. However, there were many people experiencing motion sickness such as dizziness and headache due to the delay time between hardware such as a device for sending a video after experiencing a VR image and an HMD for reproducing an image. The system proposed in this paper focuses on the environment rather than the movement of the attraction and detects the dividing line existing on the path by the proximity sensor and accurately calculates the position on the path according to the user 's motion. Since the position of the user is synchronized with the VR image, the position error of the user is improved to 0.2%.

Recently, the progress of smart phone market has retarded by oversupply therefore wearable computer has been the focus of new growth engine. Wearable computing system is a complex fusion of a variety of technologies such as wireless network, embedded, sensor and new material. Because these technologies involves utilization and mobility in addition to quality characteristic in existing software, application of ISO/IEC 9126 is not perfect when assessing quality of wearable computer. In this study, author suggested new quality assessment model for wearable computer by sorting quality attribute in ISO/IEC 9126 and adding new quality attribute. For this, author investigated features and functional requirements related to wearable computer. and then author suggested quality standard and metrics by identifying quality characteristic. Author confirmed practicality of quality assessment model by using suggested model in scenario and comparing quality assessment of three goods such as company S, L, G. This quality assessment model is expected to use guidelines for assessing quality of wearable computer.

This study is about design for the Rotational Instrument of the Industry factory which is used management safety and maintenance. We developed the multichannel vibration monitering system of the self-diagnosis for middle level CMS(Condition Monitoring System) market, and that system are new features to the expandability and flexibility. Normally one channel is used for treating one signal, but developed instrument can treat four channel with one signal processing card. One rack have redundant power supply and displace and it can check vibration measurement value in field without computer. Bearing fault detection is fundamental of vibration surveillance, but sometimes can not check with vibration velocity and acceleration. So it need the filtering and the amplitude modulation on the acceleration enveloping technology when irregular vibration is happened. We developed the vibration analysis instrument which is applied such technology. And the development prototype shows activated within the vibration error limit.

As the mobile device supply is increasing currently, the era of N mobile devices per person has opened. Types of mobile devices and OS are increasing continuously. Samsung and Intel are developing TIZEN, the OS mobilized by UBUNTU of Linux is going to be released as well as the market share of Google's Android and Apple's IOS remains above 90%. However, it is a reality that there are not specific technologies or systems which can share files between different OS. Despite of technologies such as Bluetooth and WiFi Direct, constraints are shown in device compatibility and file formats. In this paper, we have studied how to share files between OS as well as mobile devices, and to share files in a wireless LAN environment of heterogeneous variety. Future research includes the mobile phone integration server system that provides services such as introduction, management, maintenance, and repair in one-touch Mobile Server that spread and building are easy.
