Reliability of embedded softwares, as one of factors which affect system reliability, is the probability of failure-free software operation for a specified period of time in a specified environment. and Embedded software is different from general package software because hardware and operating system are tightly coupled to each other. Reliability evaluation models for embedded softwares currently used do not separate estimation and prediction models clearly, and even a standard model has not been proposed yet. In this respect, we choose a reliability estimation model suitable for embedded softwares among software evaluation models being used, and modified the model so as to accomodate recent software environments. In addtion, based on the model, the web-based reliability prediction tool RPX is developed. Finally, an embedded software is analyzed using the tool.

This study examines the demand for agricultural information at farm level, using Probit and Logit models. 646 farmers are surveyed with a questionnaire to attain the data and 441 of them have responded. The demand functions for computers, agricultural softwares, and agricultural databases at from level have been derived and used to project the demand for agricultural information in year $2001{\sim}2004$. Results find that only 5.89% of farmers have PCs at farm and rarely use the agricultural databases and softwares in 1994. The low demand figures are mostly due to the difficulty of using the PCs, databases, and softwares. The demand figures will increase in early 2000`s with 15.46% of farmers having PCs. User Friendly developed softwares and databases, and education for using agricultural information are necessary to increase the demand figures.

임베디드 소프트웨어의 디버깅은 일반 소프트웨어의 디버깅과는 많이 다르다. 예를 들어 임베디드 소프트웨어 디버깅에는 일반 소프트웨어의 디버깅에는 필요하지 않는 전력 소비량에 대한 정보, 실행된 명령어 분포에 대한 정보, 사용된 레지스터 분포에 대한 정보, 프로그램 수행 시 소요된 클럭 수에 대한 정보 등이 추가적으로 더 필요하다. 본 논문은 임베디드 소프트웨어가 수행되는 마이크로프로세서의 명령어 집합 시뮬레이터를 이용하여 임베디드 소프트웨어를 효과적으로 디버깅하는 새로운 방법을 제안한다. 본 연구에서는 국산 임베디드 마이크로프로세서인 SE1608의 명령어 집합 시뮬레이터를 기반으로 디버거를 개발하고 이를 사용하여 임베디드 소프트웨어 벤치마크 프로그램으로 많이 이용되는 MiBench 프로그램을 사용하여 임베디드 소프트웨어를 효과적으로 디버깅하는 보기를 제시한다. 본 연구에서 제시한 디버깅 방법은 기존의 디버깅 방법에 비하여 비교적 구현하기도 쉬우면서 많은 장점이 있는 것으로 판단된다.

This paper introduces an hypermedia program supportable for teaching secondary and upper secondary level geometry. This program links users to files written in other softwares and internet web sites to provide information and exploratory environments with softwares. The linkage with the interactive dynamic software(GSP) files to teach hyperbolic geometry is illustrated with sample screens.

90년대 이후부터 스토리보드의 디지털화가 꾸준히 연구되어 오면서 많은 종류의 스토리보드 소프트웨어들이 탄생하게 되었다. 그러나 이러한 소프트웨어들이 기존의 방식에 비해 효율적으로 어떠한 차이점이 있는지에 대한 구체적인 데이터가 부족하여 85명의 실험대상자에게 사용빈도수에 따른 스토리보드 소프트웨어 5개를 선정하여 사용성을 분석해 본 결과 크게 2가지의 결과를 도출해 낼 수 있었다. 첫째로는 선정된 5개의 소프트웨어 모두 상호작용 표현기능이 누락되어 있어 이것의 개발방향을 제시 할 수 있었으며. 둘째로는 스토리보드 소프트웨어로 얻을 수 있는 가장 중요한 효과는 콘텐츠의 디지털화가 아닌 콘텐츠의 실시간 플레이를 통해 얻을 수 있는 정보 전달력에 있다는 것을 실험을 통해 알 수 있었다. 본 연구를 통하여 얻은 결과는 소프트웨어의 개발자에게 새로운 모델을 제시 할 수 있으며 사용자에게는 스토리보드 소프트웨어를 통해 얻을 수 있는 효과를 이해하는 데에 도움이 될 수 있기를 기대한다.

The purpose of this research is to provide for some useful data for computer-related courses of the landscape science, assuming that computers are being and should be used more and more in landscape architecture and therefore, that landscape science students need to respond positively to such a trend. For this purpose, landscape architecture studios and their landscape architects were surveyed for their computer and its program uses as well as their satisfaction with the utility of computer for their landscape works. The results of this research are as follows; 1) 10.7% of the landscape architects surveyed answered that they had learned about their necessary softwares at school, while 61.6% of the studios surveyed were less satisfied with their employees' poor computing ability. Such findings suggest a lack of computer-related courses in landscape science and therefore, that more computer-related courses should be introduced for landscape science students together with the necessary software education. 2) Too few landscape softwares are being used by the landscape architecture studios; such softwares as AutoCAD, Photoshop, 3D Max, Excel, PowerPoint and 한글 account for more than 90% of the landscape architecture softwares being used currently. Quite naturally, landscape students need to be trained on these softwares above all. 3) It was found hat he area of work using the computer most was ˝design works˝(84.5%), followed by ˝documentation˝(83.8%), ˝image editing˝(75.1%), ˝cost calculation˝(68.2%), ˝presentation˝(68.1%), ˝analysis˝(37.8%) and ˝rendering˝(35%). It was regretable to discover that such areas requiring more computing work as ˝analysis˝ and ˝rendering˝ were still worked manually. So it sis deemed necessary for landscape science courses to enhance their computer education of such areas first of all.

Service Oriented Architecture (SOA) is rapidly emerging as the efficient approach in contemporary complex, heterogeneous computing environments. SOA increases the adaptability by loose coupling and its main feature is that three elements such as service provider, service requester and service registry are connected with each other systematically. To design the service-oriented system efficiently, a metric to measure the coupling between services accurately is needed. In this paper, we propose four coupling metrics for SOA based softwares. First, we suggest a coupling metric for service-oriented systems by modifying an established coupling metric of object-oriented systems. Then we suggest another coupling metric which includes indirect coupling between services. We also suggest two relative coupling metrics to measure coupling between subsystems. We investigate the theoretical soundness of the proposed metrics by the axioms of Briand et al. Finally, we apply the presented metrics to an industrial-scale case study.

The size of software collection at any organization is increasing rapidly with the use of computer becomes popular for various applications. This trend points out the importance of proper 'catalog'or 'directory' for software collections, however, only 'title list' is found in practice. The problem of no proper directory with software collection would be more serious than the problem with book collection since browsing is not possible with softwares. Many of the expensive softwares will be a waste of money to purchase and to hold if no catalog about them is provided. In this paper the difficulties in applying AACR2 to software cataloging and the most important characteristic of computer software are discussed as well as presenting the necessity of localized information due to the requirement of a machine to be used, the difficulty using subject-based-call-number scheme, an expected way of searching software to design a location indicator, software qualifications to be cataloged, and so on. In addition, an analysis of randomly selected softwares after a cataloging practice is followed.
