Investment in public sector information services has been on the rise in recent years. The supply of high-speed Internet and smartphones has become more common, and the stability of the information system provided to the public in the public sector has become an important management factor. In other words, tasks such as handling civil complaints and issuing certificates by public institutions, financial transactions by banks, customs clearance work, and e-commerce by individuals or institutions are mostly done online. Therefore, how to deal with obstacles arising from the information system, which is in charge of important civil service affairs, is becoming a very important issue. In other words, in the case of a disability that does not function normally even for a short period of time, various problems can occur when the work is delayed, as well as causing serious financial damage to the civil petitioner. This could be accompanied by a decline in public confidence and various other damages such as filing civil complaints. The reasons for the occurrence of information system failures are very diverse and realistically difficult to predict when. Among the various measures to cope with disability, this paper proposed a plan to establish a disability situation notification system that can minimize confusion caused by disability in the event of a homepage malfunction. The proposed disability situation notification system was established in the public IDC environment to show the possibility of utilization.

전자 상거래 시대가 도래했다. IDC 리서치의 조사 결과에 의하면, 웹에서 이루어진 거래의 총액은 1996년에 26억 달러였던 것이 2001년이 되면 2000억 달러로 증가할 것이다. 그동안 기업의 웹 사이트를 그저 구경만 하는 정도에 지나지 않았던 사용자들도 웹에서 많은 돈을 쓰기 시작했다. 이러한 붐이 조성된 요인은 매력적인 웹 검색 도구들이 개발된 점과 '쇼핑로봇'이라고 하는 영리한 쇼핑 에이전트 덕분이다.

시장조사기관인 IDC는 2002년께 웹폰이나 디지털TV, 셋탑박스, 디지털 비디오 같은 임베디드 시스템이 PC시장을 앞설 것으로 내다보고있다. 이에 따라 이 시장을 둘러싼 업체들의 경쟁이 치열하게 펼쳐지고 있는데 이러한 임베디드 시스템에 필연적으로 사용되다시피하는 것이 바로 실시간 운영체제(RTOS:Real-Time Operating System)이다. 실시간 운영체계가 가지는 특징, 응용분야, 그리고 인터넷 상에서 실시간 운영체계의 정보를 얻을수 있는 방법에 대해 간략하게 소개하고자 한다.

IDC 보고서에 따르면 전세계적으로 2004년까지 전자책 콘텐츠 판매량은 연평균 127% 성장이 추정되며, 2004년도에는 출판시장의 10%인 39억달러에 이를 것으로 추정하고 있다. 국내 전자출판 시장규모도 1,000억원대에 이를 것이라고 한다(2003년도 국내 디지털콘텐츠산업 시장조사 보고서, 한국소프트웨어진흥원).

In this paper, a bandpass filter with excellent cut off characteristic due to transmission zero using bypass coupling capacitor and with superior harmonic characteristic by interdigital capacitor is suggested. The measurement results for SIR bandpass filter with bypass coupling capacitor and interdigital capacitor show that the insertion loss is less than 1.9 dB and the return loss is better than 15.4 dB with 4.2 % bandwidth at the center frequency of 5.78 GHz.

Moments of stationary intervals and those of the counting process can be used for moment fittings of the point processes. As for the Markovian arrival processes, the moments of stationary intervals are given as a polynomial function of parameters whereas the moments of the counting process involve exponential terms. Therefore, moment fittings are more complicated with the counting process than with stationary intervals. However, in queueing network analysis, cross-correlation between point processes can be modeled more conveniently with counting processes than with stationary intervals. A Laplace-Stieltjies transform of the stationary intervals of MAP (3)s is recently proposed in minimal number of parameters. We extend the results and present the Laplace transform of the counting process of MAP (3)s. We also show how moments of the counting process such as index of dispersions for counts, IDC, and limiting IDC can be used for moment fittings. Examples of exact MAP (3) moment fittings are also presented on the basis of moments of stationary intervals and those of the counting process.

The existing tutoring estimation systems using the authoring tools or HTML forms on the Web environment don't have been improved inconvenient factors of uni-directional interactive systems. In this paper, we design and implement the interactive tutoring estimation system which is conveniently considered to user on the internet environment. The proposed system is divided into teacher and student modules, which have the functions of the new problem insertion and deletion in database, regular examination marking for the former and lecture/test selection, scoring look, etc for the letter. The environment of server system in this thesis is implemented using the IDC file and SQL database for internet access based on Windows NT, client systems are composed to Windows 95 environment based on Explorer or Netscape to access for interactive tutoring systems.
