  • As Internet, and hardware technology are in rapid process, using rate and penetration rate of Internet of Things are increasing. Internet of Things is the physical objects with network which embedded with electronics, software, sensors, and network. Smart Home-kit to operate refrigerators, washing machines, light bulbs, and such internet of things by a smartphone has been realized. However, it is difficult to use a good quality of software based on IoT. It is because that the study related to quality evaluation of software based on IoT is deficient compared with increase amount of IoT devices. Software based on IoT includes mobility, transportability, real time accessibility and hardware characteristics. Therefore, it is necessary to have differentiated quality standards and quality model. Software quality evaluation model for IoT is proposed to satisfy these needs. Evaluation model is mapped by characteristics of IoT software based on ISO/IEC 25000's quality characteristics. Scenario based studies were applied to quality model for verification.

  • This study was carried out to investigate the quality characteristics of yoghurt with varying contents of Sanmeoru (Vitis amurensis Ruprecht) wine (SW). Yoghurts were fermented with 2 kinds of lactic acid bacteria (Streptococcus thermophilus and Lactobacillus bulgaricus; Yo-$MIX^{TM5}505$, Danisco, Denmark). The changes in quality characteristics were investigated during fermentation and storage, and anthocyanin composition was analyzed after fermentation. The pH decreased in all treatments, while titratable acidity and viscosity gradually increased during fermentation. The viscosity of the yoghurt with 5.0% cultured SW added was higher than in other groups. The viable counts of lactic acid bacteria gradually increased during fermentation. The sample of the 5.0% cultured SW-yoghurt was higher than that of the other groups. The pH slowly decreased during the storage period; this was lower in the control yoghurt than in the yoghurts containing SW, and the changes of titratable acidity in the samples containing 5.0% and 30.0% cultured SW were lower than that in the yoghurt containing 1.0% cultured SW and in the control. The change in viscosity and number of viable cells during storage was higher in the yoghurts containing SW than in the control group. The levels of anthocyanin increased with the SW content in the yoghurt. Sensory scores for taste of the yoghurt with 1.0% added SW was significantly higher than for the other groups. Yoghurt with added SW kept at $4^{\circ}C$ for 12 days retained its quality characteristics fairly well.

  • Software 개발 과정 전체에 걸쳐서 적절한 도구의 활용은 개발의 품질과 생산성을 크게 향상시킬 수 있는 수단이다. 근래에는 상용 도구들 뿐 아니라 공개 (open source) software 기반의 개발 도구들도 많이 나와 있다. 그러나 이러한 도구들의 실제 활용률은 높은 편이 아니다. 본 논문에서는 많은 공개 software 기반의 개발 도구들 중에서 사용 빈도가 높고 우수한 도구들을 선정하여 그 도구들의 유형을 일반과 embedded software 용으로 분류하고, 일반 software 용 개발 도구들을 3 단계로 나누어 점진적으로 도입하는 기준을 제시한다.

  • It is no simple matter to measure and manage the quality of Software which is invisible. However the importance cannot be ignored as the software development project is getting bigger and complex. This study analyses and compares the methods of software quality improvement. Further it formulates rules for Code Inspection and verifies the efficiency and the effectiveness by applying to practical project. The study get the following results. First, the study organizes theoretical content about the methods of Software review. Second, the study formulates rules for Code inspection and demonstrates the result through the case study. Third, the study performs the quantitative dater management through code inspection.

  • Standish Group 조사에 의하면 1994년부터 2004년까지 10년간 소프트웨어 프로젝트의 원가 초과율이 180%에서 56%로 낮아졌고 납기 초과율은 164%에서 84%로 낮아져 프로젝트의 품질 수준이 높아진 것으로 조사되었다. 이러한 결과의 교훈은 SW 프로젝트를 보다 작은 시간 프레임으로 나눠 짧은 시간 프레임 내에서 설계, 프로토타이핑, 개발, 테스트를 반복적으로 수행하고 소프트웨어가 자라는 방식의 프로세스 적용이라고 설명했는데 이러한 특징을 갖는 것이 바로 애자일(Agile:기민한) 방법론이다.[1] 그렇다면 애자일 방법 적용이 과연 프로세스 품질 성숙도를 어느 정도 충족시킬 수 있는지에 대한 접근도 이제는 필요하다. 본 연구에서는 웹 서비스 제품 개발 프로세스에 Agile 방법론 중 하나인 Scrum 방법론을 적용한 조직의 사례를 통하여 프로세스 품질 성숙도 요소 충족 여부를 분석함으로써 애자일 방법론을 적용한 조직의 프로세스 품질 성숙도 측정에 도움을 줄 수 있을 것이다.

  • Recently, increasing attention has been paid to building the software quality and software productivity due to ongoing software crisis. To overcome such problem, one of the many alternatives is to use the capability maturity model (CMM) suggested by the Software Engineering Institute(SEI), focusing on the improvement of software progress. This research is proposed the theoretical framework for CMM based on the previous studies, and review the status of software process on the software development organization. We then examine the impact of the software process capability on the organizational performance including financial measures and non-financial measures. Hypotheses on software process capability were tested 144 organizational units. The 62.5% of foreign companies are distribute to the second and third level, the Korean firms in this study are indicated the first level. Result indicate that maturity of software process may be served the key predictor of organizational performance, in particular the positive relationship between the software process and non-financial performance index such as customer service, IT Infrastructure, marketing, supplier and purchaser, production and operation.

  • 최근 개인정보 유출 등으로 인해 정보시스템의 보안약점 및 소스코드 품질에 대한 관심이 높으며, 특히 개인자산과도 관련된 금융 정보 시스템의 경우에는 더욱 높다. 해당 시스템의 보안성 강화를 위해서는 개발단계에서부터 보안취약점과 코드의 품질을 높일 수 있는 정적분석 기반의 진단도구 활용이 중요하다. 많은 분야에서 진단도구의 활용이 이루어지고 있지만 금융 정보시스템의 경우 다른 SW 와 특성이 다르기 때문에 추가적인 진단규칙이 반영된 진단도구의 활용이 필요하다. 본 논문은 여러 진단도구 중 전자정부개발에 사용하고, 비교적 진단규칙 추가가 용이한 PMD 에 추가 진단규칙을 반영한 후 생명보험 정보시스템에 적용하고 이에 대한 PMD 검출 계수를 분석한다.

  • For high-quality software development, it is necessary to detect and fix the defects inserted. If defect management activities are not properly performed, it will lead to the project delay and project failure due to rework. Therefore, organizations need to establish defect management process and institutionalize it. Process standard models handle defect management in the area of project monitoring and control. However, small organizations experience difficulties in implementing and applying defect management process in a real situation. In this paper, we propose a defect management process for small organization which is designed in accordance with the characteristics of a small projects such as few participants and short development period. The proposed defect management process will be based on a tool chain with open source software such as Redmine, Subversion, Maven, Jenkins that support a defect management process and SW Visualization in systematic way. We also proposed a way of constructing defect database and various methods of analyzing and controlling defect data based on it. In an effort to prove the effectiveness of the proposed process, we applied the process and tool chain to a small organization.

  • The purpose of this research is the establishment of optimal processing and the quality improvement of confectionary analysis of the damaged starch content of flour. I studied the rheological and bread making properties of the dough containing different damaged starch content. I examined rheological and physico- chemical characteristic farinograph, extensograph and amylograph with DNS, CWRS and SW containing 6.5%, 8.2%, 9.0%, 9.0% and 10.5% of damaged starch. And I measured the hardness and specific volume and performed the functional survey by rheometer for quality control. In the amylogram, at the damaged starch content 9.5% at such the maximum viscosity was 900 B.U. the volume of bread fermention tolerance were increased. In addition, the extensegram after 135 min showed that maximum resistance of the dough were 570 B.U at the damaged starch contents of 9.5% and the bread had homogeneous air cells and internal structures at the damaged starch contents of 9.5% at which the area(A), resistance(R) and R/E value of the dough were highest.

  • If the automated image calibration system is performed in the position of non-experts, an expert will be required in every case inefficiently. But this requires an expert only when absolutely necessary. As well as the rapid system operation and efficient workforce can be managed. Image correction to perform projector inspection and management skills and to filter SW plug-in correction is that special theater system maintenance is not only managed efficiently, but also combined image analysis techniques can improve the technical perfection. This paper is to minimize the economic loss by developing a 10-bit High-depth and high-resolution $360^{\circ}$ projection image analysis technique and is to development of the special theater calibration system to effectively support quality.
