The SP quality assessments from national IT industry promotion agency of Korea(NIPA) assesses ability of software development process. And the SP quality assessments is getting popular over the nation. But, in the SP quality assessments, there is no concern about security attribute. In this paper new secure process base on ISO 27001 is proposed for the organization that is already passed SP quality assessments. This process can detect security threatening factors and gives chance to protect those factors. Furthermore, since detected security weaknesses can be used as a measurement, the system can be managed in aspect to security attribute.

A software to calculate diffraction OTF from lens design data was developed and its accuracy was verified. To verify the accuracy, MTF of a standard lens system for OTF measurement were calculated. The results were compared with calculated values by another commercial software and measured values. We found that they have good agreements with one another.

Recently, Korean software industry has enjoyed fast growth, thus phenomenon drew attention to the need for more precise and standardized cost estimation system for software development. However, many obstacles exist in achieving a more precise and universally applicable cost measurement. These obstacles include : (1) the intangible nature of intellectual efforts, (2) lack of cost standards, (3) lack of quantitative yardstick to determine the potential complication, (4) lack of both cost monitoring during development and coordinating between acquisition process and cost estimation. The purpose of this study is to facilitate software development cost estimation considering acquisition process that will meet korean user's needs, and to create better models that will be cost for software development particularly for Korean environment.

SQM (Software Quality Metrics) is a methodology whose primary objective is the measurement of compliances to requirements using a set of software life cycle properties called quality factors, which is based on the hierachical relationshiips between factors, criteria and elements. For this study, two factors (Correctness, Maintainability) and five criteria were selected. In addition, several tens of quality elements were developed to su, pp.rt them. Qualities of three computer programs which are being used for engineering purpose were measured. As a result, it is concluded that SQM is a valuable method for continuously monitoring the pulse of software quality development and that it can be used as a tool for software quality assurance.

There is currently a focus on usability of interactive computer software. Previous research in software ergonomics has indicated the importance of evaluating the usability of software user interfaces. Software developers, interface designers or human foctors engineers often confront the task of comparative evaluation among systems, versions or interface designs. This study presents a structured model for comparative evaluation of user interface designs using usability criteria and measures. The proposed model consists of twomain phases : the prescreening phase ad the evaluation phase. The first phase involves expert judgment-based approach with qualitative criteria. The prescreening phase uses absolute measurement analytic hierarchy process to filter possible altermative interfaces to a reasonable subset. The second phase involves user-based approach such as usability testing, with quantitative criteria. The objective of the evaluation phase is to evaluate a subset of altermatives using objective measures. A set of criteria and measures for evaluating the usability of computer software designs is presented. The proposed model provides practitioners with a structured approach to select the best interface based on usability criteria and measures.

In this paper, we attempt to prevent certain cases by tracing a history and making genogram about open source software and its modification using similarity of source code. There are many areas which use open source software actively and widely, and open source software contributes their development. However, there are many unconscious cases like ignoring license or intellectual properties infringe which can lead litigation. To prevent such situation, we analyze source code similarity using program dependence graph which resembles subgraph isomorphism problem, a typical NP-complete problem. To solve subgraph isomorphism problem, we utilized harmony search of metaheuristic algorithm and compared its result with a genetic algorithm. For the future works, we represent open source software as program dependence graph and analyze their similarity.

SPL 방법론을 적용하여 개발한 제품군 시험은 모든 제품에서 사용되는 공통 부분과 일부 또는 단일 제품에서만 사용되는 가변 부분을 종합적으로 고려해야 하기 때문에 단일 소프트웨어 시험과는 상당히 다르다. 시험 커버리지는 작성된 시험에 대한 적절성을 측정하는 데에 사용되는 동시에 적절한 시험을 작성하기 위한 가이드로 사용되기 때문에 중요하다. SPL 시험에서 시험 커버리지 측정은 제품군을 구성하는 멤버제품 별로 측정될 수도 있지만, 이는 재사용을 기반으로 중복된 개발관련 활동의 최소화를 지향하는 SPL 의 원칙에 맞지 않다. 따라서 개별 제품이 아닌 SPL 수준에서 시험 커버리지 기준을 측정하고 시험의 적절성을 평가하기 위해서는 다른 방법이 필요하다. 이 논문에서는 구성가능한 소프트웨어 시스템(highly configurable software system)에 SPL 시험 방법을 적용하여 SPL 기반 제품군을 위한 시험 커버리지의 측정 방법을 제안하고 실험의 수행 결과를 기술하여 제안한 방법의 적절성을 검증한다.

Objective : Computed tomography (CT)-based method of three dimensional (3D) analysis ($MIMICS^{(R)}$, Materialise, Leuven, Belgium) is reported as very useful software for evaluation of OPLL, but its reliability and reproducibility are obscure. This study was conducted to evaluate the accuracy of $MIMICS^{(R)}$ system, and inter- and intra-observer reliability in the measurement of OPLL. Methods : Three neurosurgeons independently analyzed the randomly selected 10 OPLL cases with medical image processing software ($MIMICS^{(R)}$) which create 3D model with Digital Imaging and Communication in Medicine (DICOM) data from CT images after brief explanation was given to examiners before the image construction steps. To assess the reliability of inter- and intra-examiner intraclass correlation coefficient (ICC), 3 examiners measured 4 parameters (volume, length, width, and length) in 10 cases 2 times with 1-week interval. Results : The inter-examiner ICCs among 3 examiners were 0.996 (95% confidence interval [CI], 0.987-0.999) for volume measurement, 0.973 (95% CI, 0.907-0.978) for thickness, 0.969 (95% CI, 0.895-0.993) for width, and 0.995 (95% CI, 0.983-0.999) for length. The intra-examiner ICCs were 0.994 (range, 0.991-0.996) for volume, 0.996 (range, 0.944-0.998) for length, 0.930 (range, 0.873-0.947) for width, and 0.987 (range, 0.985-0.995) for length. Conclusion : The medical image processing software ($MIMICS^{(R)}$) provided detailed quantification OPLL volume with minimal error of inter- and intra-observer reliability in the measurement of OPLL.
