소프트웨어 개발 프로젝트에서는 다양한 개발 방법론을 적용해서 소프트웨어가 개발되고 있으며, 최종 목표 소프트웨어 및 시스템에 따라 최적의 개발방법론이 적용한다. 개발프로세스 단계에 따라 모듈을 개발하며 최종적으로 통합 단계에서 하나의 소프트웨어로 통합하고 있다. 하지만 프로젝트가 복잡하고 모듈별 의존도가 높을 경우 각 모듈 별로 개발된 코드는 많은 요구사항의 변경, 형상관리 미흡 및 표준 미 준수 등으로 모듈 통합이 완벽하게 진행되지 않고 있으며 그로인해 프로젝트 기간안에 완료하지 못하는 상황이 빈번하게 발생한다. 통합이 완료되지 못하면 소프트웨어 품질은 낮아 지고 프로젝트 비용 및 시간은 늘어나 결국 프로젝트가 실패 할 가능성이 높아진다. 각 모듈의 통합을 예측 가능하고 성공적으로 하기 위해 지속적인 통합 시스템을 구축하여 프로젝트에 적극적으로 적용하고, 공개소프트웨어 도구를 활용하여 자동화 시스템을 구축해야 한다. 국내에서는 지속적인 통합방법의 중요성을 인식하고 있지만 프로젝트 비용. 시간, 인식부족 및 도구의 부재 등으로 인해 소프트웨어 프로젝트에 활용되고 있지 않은 실정이다. 이에 본고에서는 공개소프트웨어 도구를 이용하여 지속적인 통합 환경을 구축하고 소프트웨어 품질개선에 활용할 수 있는 테스트 방안을 제안한다.

The standard numerical approximation of structural displacement field leads to the thickness-wise transverse shear stress distributions which are quite different from the exact ones. To overcome this inherent problem, an effective and reliable post-processing method is presented based on the strain recovery and the stress equilibrium, particularly for functionally graded cylindrical and conical elastic panels. The present method is developed in the framework of locking-free 2-D natural element method. Through the recovery of displacement component-wise derivatives, the element-wise discontinuous in-plane strain distributions are enhanced to be globally continuous and smoothened. And, using the continuous in-plane strains, the troublesome poor transverse shear stress distributions are enhanced through the thickness-wise integration of static equilibrium equations. The validity of present post-processing method is verified through the comparison with the reference solutions. In addition, the comparative experiments are also performed to investigate the difference between the present method and other available post-processing methods. The numerical results confirm that the present method provides the accurate transverse shear stress distributions which are consistent with the reference solutions and much better than other available methods.

The successful management of software (SW) projects is a continuous concern to managers, which is attributed to the contradictory demands that most projects are facing; meeting user requirements within time and budget limit while flexibly dealing risks during the progress of the projects. The present study asserts project performance and risk mitigation are not tradeoff but to be achieved simultaneously, which is called SW project ambidexterity. Drawing on the literature on organizational behavior, hypotheses are developed speculating the relation among project performance, risk mitigation, team collective improvisation, team behavioral integration, and team diversity. Using empirical data collected from 102 SW project teams of 507 team members in South Korea, empirical analysis indicates team collective improvisation is a significant antecedent to SW project ambidexterity, playing a pivotal role to balance the contradictory demands. Furthermore, team behavioral integration positively influences the degree of team collective improvisation, and the magnitude of the relation is partially contingent on the team members' age and major diversity. The present study advances theory by providing a context specific explanation about the SW project ambidexterity and its precedents.

When we make a place for people, interior space and exterior space are always connected, each influencing the other. To create a better space or increase the quality of an existing space, it is essential to look at the relationship of inside and outside and their boundaries. Without consideration of the landscape, the building itself gives only limited satisfaction to people. This is an important issue for anyone who deals with space. This study intends to explain the important need for a change in attitude towards our built environment and its intrinsic relationship with its natural context. In the study, I try to find design concepts for integration of inside and outside which have accumulated since early Modernism designers and consider cases with different solutions and approaches that make total design sense when looking at the inside and outside as a whole, then, through observation of the cases, I find 5 design methods(Opening, Continuing, Insulting, Wrapping, Interpreting) in connecting the two spaces and analyze the solutions. The various examples which are shown in each patterns will help us to find ideas for the best solutions of integration of inside and outside. It is true that the idea of integration of inside and outside will increase the quality of our environment and it comes with the current thoughts of ecological and sustainable design. Thereby, I suggest designers to change their manner to continuous and integrated point of view in dealing with built environment.

Purpose As the mobile easy payment service grows fast, competition in the payment service market is getting stronger. On the other hand, there are few studies on the users' utilization results. Therefore, this study explains the continuous use intention of mobile easy payment Services based on PAM and value model. Design/methodology/approach This study proposed an extended model by integrating PAM, which is a representative model of continuous use intention in IS field, and value model of mobile field. Also this study empirically tested 298 users who have experience of mobile easy Payment service. The structural equation model was used to verify the research model and hypotheses. Findings According to the empirical analysis result, this study verifies that perceived usefulness and satisfaction were determinants of continuous use intention in mobile easy Payment services. Expectation confirmation has been proved to be a positive predictor of satisfaction and perceived usefulness. Also, among the value factors, perceived ease was not a valid predictor of satisfaction, and the remaining factors were positive predictors of satisfaction.

Since the skew beam element has two curvatures which are a curvature and a torsion, spatial behavior of curved beam which cannot be included in one plane can be anlayzed by emploting the skew beam element. The $C^{0}$-continuous skew beam element shows the stiffness locking phenomenon when full integration is employed. The locking phenomenpn is characterized by two typical phenomena ; one is the much smaller displacement thant the exact one and theother is the undelation phenomenon is stress distribution. In this paper, we examine how unmatched coefficient in the constrained energy brings about the locking by Reduced Minimization theory. We perform the numerical ones. These comparisons show that uniformly full integration(UFI), which employs full integration for the constrained energy, entails the locking phenomenon. But the use of uniformly reduced integration(URI) of selectively reduced integration(SRI), which employs reduced integration for constrained energy, does not produce the significant errors of displacements of the undulation phenomenon in stress distribution since they do not entails the locking, Additionally, the error due to the approximated parameters for describing the geometry of skew beam is examined.d.
