As the business has been highly informatized, many companies has bought the software for their works. There are two types of software license. One is a site license and the other is a user license. This paper is focused on the user license. User license has the number of the right to use software. So, software managers always need to know the number of licenses in use and should limit the number of software license in use. If someone in the company use a software without license, he will be treated as a piracy. In that case, the company should pay for the settlement cost for the exceeding license use. In this paper, we suggest the model how we can limit the installation of the software within the number of licenses by license management system.

The number of cellular phone users has exceeded over twenty million recently. Some researches show that people in the twenties to thirtieth usually regard the cellular as an instrument for not only call but also Internet. It means the cellular is being highlighted as a mediator for transmitting information. Therfore it'll play an essential role soon as a gateway for unifying wire and wireless services if we can browse Internet sites, for example our own homepage or commercial site, with the cellular. This paper explain WAP topology which enable the mobile terminal to access to the Web and show a method of designing and realizing WML document on the Web.

It is a tendency for enterprises in the domestic construction field to harness the system scaffolding with an aim to securing safety, despite slight increase in terms of the construction cost. Nevertheless, given that putting the system into service in reality is not accurately surveyed by far and that safety standards and methods for safe work therewith are not yet established, hazardous factors involving the system scaffolding remain latent leaving unrecognized. In this regard, the current study attempts to understand the status of implementation and use of the system scaffolding in the local construction sites as for the year 2009 and the year 2013 through questionnaire surveying and in-depth interviewing, while further proposing, based on the result thereof, ways for activating introduction of the system scaffolding in an effective and systematic manner.

Due to the improvement of PC performance and windows-based OS, PC-based control system is gradually taking over industrial control in the industry site, replacing the closed proprietary syste. PC-based system gives the avantages of ease-of-use, cost-effectiveness, simplicity of maintenace and the flexibility to design I/O system using standard technology. While there are many real time software soltions, most of hardware solutions are closed, vendor-depednent, proprietary systems for large scale plants. In this paper, we suggest the method to configure PC-based I/O system based on standard technology which gives the avantages to use off-the-shelf products for system integration.

This paper presents a comprehensive review of recent advances in ultra-high performance concrete (UHPC). Fundamental characteristics of UHPC are elaborated with focus on its material constituents, mixing, and formulation procedures. Use of state-of-the-art materials such as carbon nanotubes or nano-silica is discussed as well, whose inclusion may enhance the performance of UHPC. The review evaluates supplementary treatment methods (e.g., pressuring curing) and identifies applicable standard test methods for determining the properties and behavior of UHPC. Site implementation is provided to link laboratory research with full-scale application. Research needs are suggested to further develop UHPC technologies from technical and socio-economical perspectives.

As the state of the art for handling Multimedia on the internet is developed a new system called WebCAM which services video and image came out. However, WebMIC site for audio services are still rare. In this work, we developed a system which enables anyone to listen audio in real-time through the internet. WebMIC system is implemented by connecting a server with a microphone and the recorded audio files are stored in a Database system. Because the microphones can be distributed sporadically, the developed system can be utilized for managing and advertizing a location. It also can be used to reduce the cost for the existing management system which is almost met by personnel expenses. Anyone who can connect to the internet can get this WebWIC service, so this system can produce a good effect if used in advertising any tourist resort.

실제 시스템 개발현장에서는 사용자 요구사항과 관련 자료의 분석을 시작으로 크게 네 가지 단계 즉, 분석, 설계, 개발, 구현단계별로 각종 명세서들을 작성하고 있다. 명세서 일부는 자동화된 도구를 사용하여 연속적으로 작성되기도 하지만 모든 명세서가 자동화로 작성되는 것은 아니다. 이로 인해 작성되는 명세서간에는 많은 불일치 항목이 발생한다. 본 논문에서는 시스템을 개발할 때 각 단계별로 작성되는 명세서에 포함된 오류를 검출하는 방안을 제안하고, 이를 기초로 명세서 오류 검출 시스템을 설계 및 구현한다.

In the Web 2.0, besides more gaining information on the web, the number of web sites that take advantage of RSS increases explosively. Commonly each users search RSS channels through the web search engine before registering RSS channel's url to the RSS reader. Users judge whether the site is RSS channel or not and register an RSS channel's url through theirs interests. Because accomplished by users themselves, those processes conflict to user's convenience and quick consumption of information. Techniques of current search engines can't provide users with reliable RSS feed information as search results. In this paper, we analysis appropriateness of current search engines' techniques that offer users RSS feed search service and discuss their limitations. Also, we make up RSS feed database through classification of RSS tag being possible to search RSS feed information effectively and apply update rate of each RSS channel's feed to ranking algorithm providing more reliable search results.

최근 컴퓨터 네트워크의 발전에 따라 해킹사고도 급증하고 있으며 그 방법도 다양해지고 있다. 이러한 시기에 정보보호에 대한 관심이 높아지면서 많은 기업이 각종 보안시스템을 도입하고 있다. 그러나 해킹에 대응하기 위해서 대부분의 보안장비가 독자적인 이기종간의 기술을 적용해 제품간의 연동과 보안요소만으로 대처하기에는 많은 어려움이 있고, 이를 운용하는데 엄청난 조직, 장비, 인력 소요가 증대되고 있는 실정이다. 이러한 문제점을 해결하고자 이기종간 침입탐지 정보에 대한 보안요소를 통합하여 해킹으로부터 효율적으로 대응할 수 있는 웹 기반 관리 시스템을 설계 및 구현하였다.
