There found limitations of mobile advertising researches in methodology, theory building, and research implication. Existing researches were basic and some exploratory studies on mobile advertising and its effects. Especially, there was not a systematic typology research on mobile advertising. This paper tried to develop a systematic and empirical typology of mobile advertising and show proper advertising cases. We classified mobile advertising using mobile channels and methods (Text, Icon, Media, and Contents), Also we used advertising effects like information offering, leading transaction and response, and channel connection in classification of mobile advertising. Finally we suggested mobile advertising cases based on this typology and analysed the performance of moile advertising.

This paper proposes a system composed of wireless sensor network and cloud to monitor storage environment of pharmaceutical products. Integration of sensor networks to cloud is an emerging architecture offering the benefits of internet for monitoring to be done easily and remotely from anywhere and anytime and at the same time freeing the sensor network from processing, analysis, computational and storage of sensor data.

본 논문에서는 Ad Hoc Network에서 사용되는 proactive 라우팅 프로토콜과 reactive 라우팅 프로토콜의 혼합인 hybrid 라우팅 프로토콜에 대해 제안하였다. 본 논문에서는 기존의 hybrid라우팅 프로토콜이 ZRP와는 달리 Ad hoc 네트워크를 구성하는 노드들 중에 네트워크 서비스를 제공해주는 특별한 노드를 설정하여 라우팅 하는 방법을 제안한다. 이러한 역할을 해주는 특별한 노드를 본 논문에서는 C-Node라 부른다. C-Node를 이용한 라우팅으로 기존의 라우팅 프로토콜보다 경로 설정 시간과 flooding시간을 줄임으로서 효율적인 라우팅을 수행할 수 있게 된다.

The knowledge of the specialized fields has been changed rapidly in the both side of quantity and quality. A hyper media as a knowledge based system is so fixed in the linked media in mutual that we couldn't tell it information provision with the view of users. In this paper, we propose the way of offering intellectual and flexible information which is the same with demand in the side of user, selecting, searching and composing the hypertext at the point of user's view through the design of knowledge media system. Three concepts are used in order to challenge the knowledge media system : special document, agent system and ontology. The special document is a ensure that its activities are coordinated with those of the others within the community, providing a uniform control mechanism. Finally, ontology is a language for exchanging knowledgement, which is a message exchanged among agents to ensure the proper interaction among them. The combination of these three concepts is used to design the prototype of knowledge media system.

The purpose of this study was to develop railroad geotechnical management system using Web GIS and the DB used in system included railroad informations and digital maps. Digital maps are primarily based on a topographical map(NGIS, 1:5000) and by adding digital maps(KRRI, 1:5000) and their spatial database system to NGI code layer, the management system was developed. The system was connected to geotechnical database already developed. The system was able to separate three parts which were layer choice, geotechnical information view and geotechnical analysis and it was possible to save geotechnical and spatial informations using ZEUS DB simultaneously. ZEUS/X was used for usefulness of GIS operation and by offering GUI, user interface for facility was achieved. Geotechnical and spatial informations in this system will provide basic data for plans, design and construction of railway lines in practical use.

In this paper we describe the design and implementation of Electrical Ground Support Equipment(EGSE) for the CBS transponder testing. The main task of EGSE is to check out satellite systems, at system or subsystem level, during integration and validation phases of their life-cycle. Through a combination of hardware and software elements, EGSE supports manual, semi-automatic and fully automated testing. Automation is achieved by offering users simple, yet powerful means to write their own test application programs (test sequences) in high-level, test-oriented language and to run them in a strict real-time environment. The core of this environment is a user-configurable real-time database, containing all the information needed to calibrate acquired data, check them against predefined thresholds, automatically react to out-of-range conditions, display data using animated graphics or synoptic windows, and so on.

In recent, android application developments have been done widely that intensify smart phone utilization. In this paper, we propose a curriculum that undergraduate students can improve their mobile programming abilities as well as integrate experiences of application development based on android. And also a series of practices to advance their sense of accomplishment are added by offering an opportunity to carry out a real project to use a variety of sensors embedded in smart phone during the course of study. The project is composed of a series of modules for implementing a trekking App that helpful to people who enjoy spending time in outdoors through their favorite activities such as trekking, cycling, and climbing with their own smart phones. Through practical curriculum operation and project implementation, we show that the proposed curriculum is appropriate to a mobile programming education that combine learning and practice.

We show how to rapidly build a framework supporting weak code mobility by using Active XML [I]. Weak code mobility is important in mobile applications area by offering functionality at a low bandwidth cost and with little overhead imposed to the user peer architecture. Starting from already known principles involving code nobility, we give a new definition for the functionality transfer p개cess and we materialize it in a working prototype.

A storm surge is gradually increased in the Korean peninsula. Furthermore, this phenomenon is confined not only the Korean peninsula but also the whole world. A storm surge induced by storm, typhoon, or cyclone is a phenomenon that the water surface elevation is raising by the barometric pressure difference and this water level rising threatens the coastal facilities, settlement, or lives. Most of coastal region in our country are unsafe from this disaster. Even though we are not able to prevent the generation of this phenomenon, we can reduce the damages by investigating the kind of storm surge disaster. Once we finish this investigation, we can reduce the damages by offering the information for risk prior to an invasion of storm surge. This study, we analyzed the previously occurred storm surge damages, and this data can be utilized as a guide for those who live near the coastal region providing the information about the predicting scale of the storm surge

본 논문에서는 앞으로 광대역통합망에서 사용자의 요구사항에 따른 QoS를 제공하기 위한 연구의 일환으로 여러 가지 서비스 모델과 메커니즘을 살펴보고, 라우팅 최적화를 위한 유전 알고리즘과 hybrid 유전알고리즘에 대하여 논한다. OSPF에 바탕을 둔 라우팅 최적화만으로 QoS가 충분하지 않은 경우 약간의 MPLS 경로가 QoS를 개선하기 위해 설정될 수 있다. 이러한 상보형 MPLS 라우팅을 위한 두 개의 MIP 모델을 제안하고, 적절한 네트워크 QoS 대책으로 네트워크 내의 최대 링크 이용을 고찰한다.
