우리나라에서 화재와 같은 재난 발생 시 현실적으로 아직까지도 빠른 상황판단과 대처가 부족하다고 생각하게 되었고, 인명피해 최소화와 신속한 대피를 위한 시스템 기반이 필요하다고 판단하여 IoT 기술을 접목시킨 스마트 빌딩 시스템을 개발하게 되었다.

One of different methods to increase the productivity of software development team is to reuse the software components which were used once. Such a reusable software components are often organized software libraries. In order to reuse effectively the software modules selected from a library, the users need information enough to search for the modules easily. This paper designs and implements the tool which provides the information about the relationship between classes to reuse software components, and makes a new class by combining the data and functions from existing classes.

Auditing plays a very important role in the process of developing and managing good quality software. The software developing proces should be audited precisely especially in the test phase. Up to the present, because auditing has depended on the auditor's experience of developing and auditing software, it has been impossible to audit objectively. It is limited to audit systematically and objectively because auditing process isn't systematized. In this paper, the auditing model to solve several problems in present auditing is suggested, a test phase audit system is developed, and the system is applied to the actual auditing process. Consequently, software administrators can establish effective software management, software developers can be supported by a highly reliable and quality software development tool, and auditors can be offered an objective audit standard.

Software inspection is widely believed to be an effective method for software verification and validation (V&V). However, software inspection is labor-intensive and, since it uses little technology, software inspection is viewed upon as unsuitable for a more technology-oriented development environment. Nevertheless, software inspection is gaining in popularity. KAIST Nuclear I&C and Information Engineering Laboratory (NICIEL) has developed software management and inspection support tools, collectively named "SIS-RT. "SIS-RT is designed to partially automate the software inspection processes. SIS-RT supports the analyses of traceability between a given set of specification documents. To make SIS-RT compatible for documents written in Korean, certain techniques in natural language processing have been studied [9]. Among the techniques considered, case grammar is most suitable for analyses of the Korean language [3]. In this paper, we propose a methodology that uses a case grammar approach to analyze the traceability between documents written in Korean. A discussion regarding some examples of such an analysis will follow.

An understanding of quality attributes is relevant for the software organization to deliver high software reliability. An empirical assessment of metrics to predict the quality attributes is essential in order to gain insight about the quality of software in the early phases of software development and to ensure corrective actions. In this paper, we predict a model to estimate fault proneness using Object Oriented CK metrics and QMOOD metrics. We apply one statistical method and six machine learning methods to predict the models. The proposed models are validated using dataset collected from Open Source software. The results are analyzed using Area Under the Curve (AUC) obtained from Receiver Operating Characteristics (ROC) analysis. The results show that the model predicted using the random forest and bagging methods outperformed all the other models. Hence, based on these results it is reasonable to claim that quality models have a significant relevance with Object Oriented metrics and that machine learning methods have a comparable performance with statistical methods.

When implementing software, there can be side effects that pose a threat to human life. Therefore, it is necessary to measure the impact of software on safety and create alternatives to mitigate and prevent threats. To conduct a software safety assessment to measure the impact of threat factors, the following components are necessary. This paper aims to classify the threat factors of software into internal and external factors and quantitatively demonstrate the impact of these threat factors.

We have processed the GPS data using several high quality GPS data processing softwares for last decade. Bernes and GIPSY II are some of them. Though these programs have different characteristics in terms of structures and processing philosophies, high quality results from these are still comparable. KASI Space Geodesy Research Division has developed several GNSS data processing softwares like the quasi real-time ionospheric parameter estimator, orbit propagator and estimator, and precision positioning estimator. However, we are currently in needs of our own comprehensive GNSS data processing software with the European Galileo system on the horizon. KASI team has worked on a preliminary pilot project for the software and is making block pieces for the software. The roadmap, the description, and brief results of KASIOPEA (KASI Orbit Propagator and EstimAtor) are presented in this paper.

Typical software developed and used by North Korea is Red Star and internal application software. However, most of the existing research on the North Korean software is the software installation method and general execution screen analysis. One of the ways to identify software vulnerabilities is file fuzzing, which is a typical method for identifying security vulnerabilities. In this paper, we use file fuzzing to analyze the security vulnerability of the software used in North Korea's Seogwang Document Processing System. At this time, we propose the analysis of open document text (ODT) file produced by Seogwang Document Processing System, extraction of node based on Document Object Mode (DOM) to determine test target, and generation of mutation file through insertion and substitution, this increases the number of crash detections at the same testing time.
