공학의 기본 원리 학습을 위해서는 원리 그림이나 도표와 같은 콘텐츠의 사용이 필요하다. 하지만 시간과 공간의 제약으로 학습이 불충분하고, 편리성과 멀티미디어 콘텐츠를 갖추지 못하면 학습의 효과도 떨어지는 문제점이 있다. 최근 Smart Phone 사용자가 증가하고, Smart Phone을 이용한 교육프로그램을 제공하여 이동 중에도 공학의 기본 원리와 같은 학습이 필요한 시점이다. 본 논문에서는 열역학의 법칙 등 열역학에 관한 학습 콘텐츠를 Smart Phone에서 구현하고자 한다. 실제 Web 서버를 통하여 무선 인터넷 통신망에서 제공되는 열역학의 교육 공학적 도표, 애니메이션, 그림, 등을 Smart Phone에서의 설계하고 구현한다. 본 연구는 교육공학과 학습 프로그램 제공을 통해 모바일 원격교육 발전에 기여할 것이다.

Recently, increased accessibility to the Internet makes it possible to access to Internet-connected devices easily. For this reason, anyone can reach and command any device that is connected to the network. But these teleoperation systems have several problems like the network time delay, data loss and development cost of an application for communication with each other. The network time delay phenomenon is the most important in teleoperation system, which disturbs a real time control. The loss data also causes some users not to send correct commands to device or not to receive correct information from devices. To develop an application to communicate between user and device, it needs a comp..

The emergence of ubiquitous autonomic computing and network environment will change the service architecture information system which will be a new application area in SCM/logistics systems. In this study we surveyed the technical trend map of ubiquitous and its application in SCM/logistics support system design. We described the evolutional model of ubiquitous computing community for SCM/logistics system. It is consisted of three view points; self-growing, autonomic, and context-aware, which will allow the decision makers to be benefited from web and mobile technology and are useful for proactive SCM/logistics support system. Finally, we suggested a cooperative research planning for the development ubiquitous system between the government research center, university, and industry research activities.

최근 기존의 설치형 어플리케이션으로 제공되던 워드 프로세서나 스프레드 시트 등이 RIA(Rich Internet Application)와 Ajax(Asynchronous JavaScript and XML)같은 기술의 발달로 구글 독스(Google Docs)와 같이 웹브라우저(Web Browser)에서 동작하는 형태의 클라우드 기반 웹 어플리케이션으로 제작되어 널리 사용되고 있다. 또한 기존의 웹 기술로는 구현하기 어려웠던 동영상 포맷 변환이나 사진이나 동영상에 필터를 적용하는 것과 같은 영상처리가 가능한 클라우드 기반 웹 어플리케이션이 등장하고 있는 실정이다. 이에 본 논문은 컴퓨팅 자원을 많이 사용하고, 장시간의 변환이 필요한 360도 영상의 변환과정에 꼭 필요한 기술인 포토스티칭(Photo-stitching)을 클라우드에서 가능하게 하는 프론트엔드 및 백엔드를 구현하고, 웹소켓(Websocket)기술을 활용하여 실시간으로 변환결과를 전달 받을 수 있도록 하였다.

Traditional Knowledge[TK] is a concept which summings up all the knowledge of traditionally inherited, includes traditional medicine, therapy, food and environments. Such traditional knowledge has been perished and neglected through industrial development. We, Korean Institute of Oriental Medicine, promotes digitalization of this traditional knowledge to support and maximize its application, principally in Traditional korean medicine. We can get opportunity of reorganize the traditional knowledge to more practical and available form by this project. And also we introduce briefly its meaning and worth, and seek for application to the study of medical history.

While .NET and J2EE bisects recent distributed environment, .NET displays "Remoting" as a technology to call remote object. Remoting is frequently used as a protocol in OLTP's WEB program development in form of RPC that exchange data in XML form under HTTP environment. Purpose of this research is to draw problems when applying security to .NET remoting technology that is recently used in web programming, and to find effective application plan by implementing. The main discussion is following. First, network layer security should be replaced to application layer security for better performance and flexibility. Second, the serialization procedure that is repeated in both remoting and encryption module should take place once. Lastly, implementation of "Surrogate" and "Compress" will be discussed that enables to eliminate unnecessary data(table relations, keys, etc) that is used in dataset object of .NET in order to reduce the size of data. It is possible to achieve improvement in speed by two times through immediate implementation in these cases. In order for easier use, component based framework should be supplied hereafter.

Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.

As the complexity of software development is increasing due to networking, multimedia, and diverse system architecture, the need for effective software development methodology is increasing. Especially, due to software standard and internalization of software market, it is necessary to accept international quality such as ISO 9000-3. In addition, object oriented development methodology is required due to rapid propagation of OO technology and standardization. Recently, UML was accepted by the OMG as standard object-oriented modeling language for distributed environment. When we UML was accepted by the OMG as standard object-oriented modeling language for distributed environment. When we develop Java and CORBA-based software, often UML is applied to Java and CORBA-based projects. However, current structural or OMT-based object-oriented methodologies. In this paper, we proposed UML-based development and concrete guidelines for each phase in order to apply UML to software development practically and effectively. Also, we define the transition guidelines and semantics between various development tasks. In addition, the analysis and design techniques of user interface and system development techniques needed in Web application development are presented.

Due to the rapid development of smart phones, smart phone users grew, expanding communication between the service users has been enabled by the application's service. Difficult to find a service that allows you to know the quality of school meals and the expectations of these applications. In addition, the existing application works only with a particular device, it is difficult to compatible devices. Thus, based on the HTML5 hybrid application were developed and this feed can be monitored by the students of the school, the communication can be formed.

This dissertation is a web-based cyber exhibition website and a clear difference between the general framework of the development breaks out, the cyber exhibition framework can be a model for the purpose of the proposal. The basic elements that comprise the exhibition model is archives layer, exhibit layer, and experience layer for the three-layer planed. In fact, the model has been applied throughout the analysis of cases with the application of the model presented, while others are considering goal direction also suggests the development of a cyber exhibition. If you take advantage of the cyber model of development brilliant display of the content rather than technology-driven 'material and value+media and CT' to the convergence of content through their own cyber exhibition area can expect to be recognized.
