This study proposed a method for determining weights for the eight quality characteristics, such as functionality, reliability, usability, maintainability, portability, efficiency, security, and interoperability, which are suggested by international standards, focusing on software test reports. Currently, the test results for software quality evaluation apply the same weight to 8 quality characteristics to obtain the arithmetic average. Weights for 8 quality characteristics were applied using the results from text analysis, and weights were applied using the results of text analysis of test reports for two products. It was confirmed that the average of test reports according to the weighted quality characteristics was more efficient.

We consider about software quality nowadays. The company considers about software quality more and more compare to software development. We analyze the software testing data in this paper. We find the software effect according to the number of testing, the number of testing date, the number of fault according to characteristics. Also, we analyze the result by regression. Also, we propose the testing effect by sex.

In this paper, we propose a method for estimation software quality in terms of software test data, and it is necessary to predict the period of time required for software test evaluation. We need a model to understand of estimation of software quality. In this paper, we propose a model to estimate the number of days for software test using the data obtained through the tester's sex, and present a model for analysing the number of errors according to six quality characteristics by software type.

In this paper, we propose a software quality measurement metrics of ISO / IEC 25023, which is newly proposed for software quality evaluation, to compare the difference with ISO / IEC 9126-2 which was used for software quality evaluation. In this paper, we propose a method for evaluating the quality of reliability based on the software reliability growth model among the eight quality characteristics presented in ISO / IEC 25023. Based on ISO / IEC 25023, software-quality evaluations demonstrate that there is some risk in evaluating reliability when based on data.

Viewpoint about the quality of software is various. But, from the end-user point of view, user interface of software may be all to express the quality of software. But the detailed evaluation criteria were not established about usability evaluation method based on user interface so far, though user interface of software is the main object of usability quality characteristics. In this paper, we established a system about the method extracting and evaluating some quality characteristics elements measurable form user interface of software by analyzing the relationship between the elements constructing quality characteristics and user interface related to quality evaluation of software. We expect that this result of study will be a fundamental study adapting and evaluating to various types of user interface.

Many people are interesting software quality. Because of, we depend on software in our life. In terms of, I think, good software is a good quality software. So, when we develop the software, we need trying to improve software quality. In this paper, we analyze software test data. We emphasize that software quality is very important in our life. We use software experimental data, in order to analyze of software quality. On the basis of ISO/IEC 9126-2, we classify the test data and we analyze the difference of error frequency according to functionality, reliability, usability, efficiency, maintainability, portability. We analyze the number of test and used time according software type. We want to search effect variable, going through testing result and measurement convergence, we know the effect variable of functionality and efficiency.

Software quality is very important in software. We think, software testing is very important in point of functionality, usability. But, we have to consider about all of the software quality. We change our thinking about software quality from time to time. In this paper, we try to the best to find important factors by the number of testing dates and the number of testing in point of functionality, usability, reliability, efficiency, portability, maintainability. We study the mean of the number of faults according to products. We find the difference the number of errors by sex of tester.

최근 하천의 유량측정에 있어서 ADCP(Acoustic Doppler Current Profiler)의 빈도와 활용범위가 점차적으로 증가하고 있다. 국토교통부의 유량측정을 전담하고 있는 유량조사사업단에서는 최근 저평수기 유량측정은 물론, 중고수위 유량측정에서도 기존 유량측정방법의 단점을 보완하기 위해 ADCP 이동보트법을 적극적으로 활용하고 있다. 현재 ADCP 이동보트법으로 측정된 유량은 제조업체에서 제공되는 소프트웨어로 산정되며 크게 두 가지 문제를 초래하고 있다. 첫째, 제조업체에서 제공한 소프트웨어는 자동으로 품질평가를 할 수 있는 기능이 제한적이고, 사용자가 측정자료를 검토하기 위해 제공되는 표와 그래프 등의 정보가 제조업체마다 일관적이지 않다. 따라서, 측정자료의 품질평가는 측정한 ADCP에 종속되고 제조업체에서 제공된 소프트웨어 기능에 한정되어 효율적인 평가는 저해되고, 일관적이지 못한 결과를 초래하여 측정자의 책임이 증가되고 있다. 둘째, 제조업체에서 제공되는 소프트웨어가 자료의 처리 및 유량 계산에 대한 상이한 알고리즘을 사용하여 제조업체가 다른 ADCP로 동시에 측정된 유량이 서로 다른 결과로 나타나 혼란을 주고 있다. 이러한 이유로 USGS(U.S.Geological Survey)에서는 ADCP를 이용한 이동보트법 측정유량 처리에 대한 소프트웨어인 QRev를 개발하였으며, 일관적이고 효율적인 자료 처리와 계산이 이루어지도록 하고 있다. 본 연구에서는 유량조사사업단에서 수행한 ADCP 이동보트법 측정유량 자료에 대하여 QRev를 이용한 자료의 처리 결과에 대하여 분석하였다. 특히, ADCP로 측정이 불가능한 수면 및 하상 영역에 대한 외삽방법들의 적용 결과 및 제조업체의 기본 설정 값들에 대한 결과를 비교함으로서 QRev에 대한 향후 국내 활용 방향을 제시하고자 한다.

This study is the result of a fuzzy-AHP-based evaluation of the support policy for the export of Chinese software, for which nine Class 1 evaluation indexes were established. Following a survey of 10 Chinese software experts, fuzzy AHP was used to assess and evaluate the absolute and relative importance of each index. The evaluation revealed that the support policy had relatively positive effects. More specifically, the analysis showed that several indices - technology development, HR development, marketing reinforcement, fund support, platform establishment, and product support - carried relatively significant importance. Quality management and tax deductions, on the other hand, showed no importance, while the importance of international certification was relatively small. In light of these discoveries, there is a need to train experts, increase software quality, and reconsider software brands.
