전자정부 표준프레임워크는 공공사업 프로젝트에서 응용 SW 표준화, 품질 및 재사용성 향상 등의 목적 하에 개발된 것으로 일반 기업에서도 도입하여 시스템 개발에 활용하고 있다. 이는 전자정부 표준프레임워크가 정부기관은 물론 일반기업에서도 효율성 향상 측면에서 중요하다. 본 연구는 전자정부 표준프레임워크를 일반기업 프로젝트에 도입할 때의 기대효과 및 문제점들을 정리하고 도입방법과 단계를 살펴보고 전자정부 표준프레임워크가 일반기업에서도 많이 활용될 수 있는 방안에 대해 연구 하였다.

국내 많은 기업들이 CMMI(Capability Maturity Model Integration) 모델을 도입해서 소프트웨어 개발 프로세스를 구축 및 내재화 후 CMU(Carnegie Mellon University)의 SEI(Software Engineering Institute)로부터 인증을 받고 있지만, CMMI Maturity Level 3 이상 인증 받은 조직에서 조차도 프로젝트 지연 및 품질 문제가 자주 발생한다. 프로젝트 지연 문제는 개발 단계 이후에 대부분 발생되고 있으며, 이는 현저히 낮은 소프트웨어 개발 생산성의 영향 때문이다. 본 논문에서는 프로젝트 개발 생산성에 영향을 미치는 중요 요인을 분석하고, 이에 따른 작업의 가치를 결정하는 방법을 제시한다.

현재 해양수산부에서 발주하여 선박해양플랜트연구소에서 주관하여 진행하고 있는 해양 디지털 항로표지 정보 협력 시스템 과제가 진행 중에 있다. 해양 디지털 항로표지 정보 협력 시스템 과제는 실증 센터 구축을 목표 중 하나로 잡고 있으며, 실증 센터 구축을 위해서는 실증센터 구축 이전에 연구개발 결과물을 유사한 환경에서 성능을 검증할 필요가 있다. 또한 해양 디지털 항로표지 정보 협력 시스템 과제는 외부의 정보를 활용할 필요가 있어 정보통신의 측면에서의 보안이 유지되는 공간이 필요하다. 이를 위하여 본 연구에서는 보안이 필요한 서비스 설치 공간와 일반사용자가 서비스를 사용하기 위해 일반적으로 접근이 가능한 공간을 연결하고, 연결 방법에 대하여 분석하였다. 또한 서비스 개발 기관에서 개발 중인 서비스 코드를 보안 공간으로 전송하여, 시스템 설치 및 SW 품질 테스트 등이 용이한 방안에 대하여 연구하였다.

In this paper, we propose a design method for the construction of LTE-based small unmanned aerial vehicle control system to quickly and reliably collect multiple small unmanned aerial vehicle position information simultaneously flying all over the country. In particular, the main requirements are the network (N/W), hardware (H/ W), software(SW), Database(DB), development architecture, and business needs. To satisfy these requirements, N/W, H/W, SW, DB design, and architectural design plan were suggested regarding the design requirements of a small UAV system. To effectively control the small unmanned multi-party system in the system design, the architecture is divided into the front-end service area and the back-end service area according to the function and role of the unit system. In the front-end service area that grasps and controls the position and state of small unmanned aerial vehicles (UAVs), we have studied the design part that can be expanded to N through TCP/IP network by applying Client PC method.

The data-driven IT project model has been improved by adding processes such as analysis/design of data structure and channels of data collection/distribution, application of data standard and securing the flexibility in IT convergence devices data configuration on existing informatization project procedure driven by HW and SW function. This model focused on the evaluation of improvement effect which warrants data flexibility of IT convergence device. IT convergence device was divided into sensor and reactor and a situation when new information system is additionally linked to these devices was assumed. The system improvement complexity and index on network environment were estimated and they were compared to existing method.

The essence of adapting education to the information age consists of two parts. One is the building of infrastructure for information education and the other is putting information and communication technology to educational use. Moreover, from a usage point of view, it is the most important thing that secures much educational software of good quality supporting adapting schools to the information age. It does mean the investigation about the plan of evaluation of educational software is important. Thus, in this study, we provide scientific information for efficient selection and use of educational software as end-users, and provide objective evaluation criteria of quality as a developer. In addition, through this research, we can lay the foundation for adapting education to the information age. For this purpose, we analyzed previous research relevant to the evaluation of educational software, divided the criteria of evaluation into three parts, educational, applicational, and technical, and develop the criteria of evaluation in detail.

The purpose of this study is to generate DSM using the stereo matching algorithm of worldview-1 stereo images and verify the accuracy of the generated DSM. To generate DSM, RPC block modeling was performed to correct RPC errors, and image matching was performed using SGM, which is a stereo matching algorithm after the epipolar image was generated. The COST for SGM was calculated by using CENSUS, and 4-paths and 8-paths were applied for COST aggregation in SGM. To verify the quality and accuracy of the generated DSM, it was compared with the LiDAR-derived DSM and the DSM generated by commercial SW. The results showed that the vertical accuracy of the generated DSM using 4-paths of COST aggregation was 1.647 m to 3.689 m (RMSE). In case of using 8-paths of COST aggregation was 1.550 m to 3.106 m (RMSE).

Despite the importance of information technology, research on information-oriented performance management and performance management methods are very insufficient. In this paper, the SSU-ITPM model, a company-wide informatization performance evaluation and management model that reflects the characteristics of the shipbuilding and marine industry with high cooperative and process complexity, was presented. This model consisted of informatization planning and project management, informatization field utilization evaluation, informatization utilization quality evaluation, informatization user satisfaction evaluation, and informatization effect achievement evaluation. In addition, through the application of Company D, the feasibility of practical application of the model was confirmed. This study is expected to provide a practical reference model for informatization performance management of ETO plant-based companies such as the shipbuilding and offshore sector.

The Testing Frontier Capability Assessment Model (TCAM) is based on ISO/IEC 9126, TMMi and TPI. Since ISO/IEC 9126, TMMi and TPI were made over 10 years ago, TCAM faces the problem that it can not assess and analyze the capability of small businesses that employ new software development methods or processes, for example Agile, TDD(Test Driven Development), App software, and Web Software. In this paper, a method to improve the problem is proposed. The paper is composed of the following sections: 1) ISO/IEC 9126, ISO/IEC 25010 and ISO/IEC/IEEE 29119 part 2 review 2) TCAM review 3) software product quality perspective comparison, and analysis between ISO/IEC 9126, ISO/IEC 25010 and TCAM 4) comparison, and analysis between ISO/IEC/IEEE 29119 part2 and TCAM and 5) proposal for the improvement of TCAM.

Character recognition is a technology required in various platforms, such as smart parking and text to speech, and many studies are being conducted to improve its performance through new attempts. However, with low-quality image used for character recognition, a difference in resolution of the training image and test image for character recognition occurs, resulting in poor accuracy. To solve this problem, this paper designed an end-to-end learning neural network that combines image super-resolution and character recognition so that the character recognition model performance is robust against various quality data, and implemented an alternative whole learning algorithm to learn the whole neural network. An alternative end-to-end learning and recognition performance test was conducted using the license plate image among various text images, and the effectiveness of the proposed algorithm was verified with the performance test.
