RESTful 웹 어플리케이션 행위 모델 기반 결함 위치 추정

장종인,이낙원,류덕산,백종문 한국정보과학회 2020 정보과학회논문지 Vol.47 No.11

Because of the nature of Web applications being more complex, larger in scale and more likely to be composed of black box components compared to traditional software systems wherein fault localization techniques are actively used, existing techniques can be only minimally applied to localize faults in Web applications. Also, existing studies to localize a fault in a complex system such as a Web application system also have limitations in capturing the indirect interactions in Web applications and suffers from the Web application’s dynamic nature. In this study, we propose a behavior modeling-based fault localization for the RESTful Web applications. The approach models a RESTful Web application as a sequence of behaviors that captures the direct and indirect interactions in the application. The modeling process is lightweight and it is not necessary to build the model in advance of the actual execution of application. The spectrum-based fault localization is then performed in the granularity of behavior pairs in the behavior model. To demonstrate the approach, a case study on the RESTful Web application built upon the YouTube Data API v3 was conducted and demonstrated that the approach can successfully resolve aforementioned difficulties and localize a fault in the RESTful Web application. 웹 어플리케이션의 규모나 복잡성이 전통적인 소프트웨어보다 커 기존 결함 위치 추정 기법을 적용하기 어렵고, 웹 어플리케이션과 같은 복잡한 시스템 대상의 연구들도 시스템 내 구성 요소들 간 간접적 상호작용과 시스템의 동적 재구성을 고려하지 못한다. 이 문제를 풀기 위해 본 연구는 RESTful 웹 어플리케이션의 실행 기록을 구성 요소들이 수행하는 행위들의 순열로 모델링하고, 그 행위 모델 상에서 결함을 위치 추정하는 기법을 제안한다. 이 기법은 직간접적 상호작용을 모두 반영하는 행위 모델을 사용하고 실행 전에 모델을 미리 구축할 필요가 없어 동적 환경에 적합하다. 기법의 평가를 위해 사례 연구를 수행하여 전체 디버깅 대상 수의 1.8%에 해당하는 순위 내에 모든 결함을 위치 추정했다. 본 연구에서 제안하는 행위 모델 기반 RESTful 웹 어플리케이션 결함 위치 추정 기법이 대규모의 복잡한 웹 어플리케이션의 디버깅 노력을 효과적으로 감소시킬 것으로 기대된다.

김미,박진호 한국IT정책경영학회 2016 한국IT정책경영학회 논문지 Vol.8 No.3

In this paper, We focuses on suggestion to Quality model of IoT Applications which are popularly used in the characteristics defined in the quality model of IoT Applications. In order to achieve this purpose, we propose IA-QM for IoT Applications. The IoT application is a complex fusion of a variety of technologies such as wireless network, embedded, sensor and connectivity. Because these technologies involves utilization and mobility in addition to quality characteristics in existing software, application of ISO 9126 is not perfect when evaluating IoT applications. It was considered to have some different views of attribute of the quality of service models in order to support convenient approach to modeling and IoT applications. We suggested new quality model for IoT applications and Metric by quality attribute in ISO 9126. We validated that the proposed model can be practiced it was applied to evaluate the Metrics.

The adoption of public smartphone applications in Korea: Empirical analysis on maturity level and influential factors

Eom, S.J.,Kim, J.H. JAI Press ; Elsevier Science Ltd 2014 Government information quarterly Vol.31 No.suppl1

With the rapid proliferation of smartphones, public smartphone applications (hereafter public applications) have emerged as a new technology and innovation toward smarter government. To assess the current status of the adoption of public applications in Korea, the authors measure the maturity level of these public applications by applying a newly developed 'public application maturity model.' In addition, the factors influencing the differences in the maturity levels of public applications are analyzed. It was found that Korean governmental agencies have adopted diverse public applications actively in an effort to deliver public services. The overall maturity level of public applications, however, is accessed as relatively low at present. Moreover, the results of the analysis of the factors influencing the maturity of public applications can be interpreted as showing that the government agencies have only followed the trend of the rapid proliferation of public applications without considering how high-level citizen-centric services could be delivered through public applications.

For accurate sampling, subjects were chosen using two screening questions. A total of 500 questionnaires were collected and finally, 467 questionnaires were chosen as effective samples, except 33 ones with unreliable responses. Then, collected data were processed, according to the study purpose. For analysis of collected data, frequency analysis, reliability analysis and were conducted using SPSS 21.0, and confirmatory factor analysis and structural equation model analysis were conducted using the AMOS 21 program. Result: According to the result of AMOS structural equation analysis, first, hypothesis 1 was adapted, since perceived playfulness significantly influenced perceived ease of use. Second, hypothesis 2 was adapted, since perceived playfulness significantly influenced the attitude towards apps. Third, hypothesis 3 was adapted, since perceived ease of use significantly influenced perceived playfulness. Fourth, hypothesis 4 was adapted, since perceived ease of use significantly influenced perceived usefulness. Fifth, hypothesis 5 was rejected, since perceived ease of use did not significantly influence the attitude towards apps. Sixth, hypothesis 6 was rejected, since perceived usefulness did not significantly influence the attitude towards apps. Seventh, hypothesis 7 was adapted, since the attitude towards apps significantly influenced behavioral intention. Conclusion: In conclusion, perceived ease of use and perceived playfulness is influenced attitudes in sports applications can be seen that attitude also affects the behavior. Recent research applications accepted around the perceived playfulness in numerous studies because there appears little difficult to understand the determinants of technology users only functional aspects of innovation. This may be considered the user`s side and seen that the subjective. In particular sport applications can have a communications, entertainment, factors that encourage playfulness of such information. If we believe this perceived playfulness to add a variable that it is suitable for high-impact research was verified from the results. This suggests that more users recognize the playfulness high to use the sport applications more positively.
