  • 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.

  • There is a growing interest in project management knowledge, project management information systems, and process improvement to systematically project execution in public sectors, achieve high performance and value, and increase the effectiveness of the overall industry. In particular, the software industry is a knowledge-intensive industry centered on professional manpower. This study examines the effect of the project managers' competences of regional SW promotion agencies on and project performance and the moderating effect of the level of project management maturity. We collected data using a questionnaire to the project managers of regional SW promotion agencies. In this study, a structural equation model was used to analyze the relationship between project managers' competences and performance. In addition, a multi-group structural equation model was used to analyze the moderating effect according to the high and low project maturity. As a result of the analysis, it was found that only contextual competence among the competences of the project manager had a positive effect on project performance. It was found that technical and behavioral competence did not have a positive effect on management and completion performance. It was found that the moderating effect according to the maturity of business management of local institutions was not significant.

  • In this study, we aimed to apply multispectral imaging (713 - 920 nm, 10 bands) for maturity classification and recognition of oriental melons grown in hydroponic greenhouses. A total of 20 oriental melons were selected, and time series multispectral imaging of oriental melons was 7 - 9 times for each sample from April 21, 2023, to May 12, 2023. We used several approaches, such as Savitzky-Golay (SG), standard normal variate (SNV), and Combination of SG and SNV (SG + SNV), for pre-processing the multispectral data. As a result, 713 - 759 nm bands were preprocessed with SG for the maturity classification of oriental melons. Additionally, a Light Gradient Boosting Machine (LightGBM) was used to train the recognition model for oriental melon. R2 of recognition model were 0.92, 0.91 for the training and validation sets, respectively, and the F-scores were 96.6 and 79.4% for the training and testing sets, respectively. Therefore, multispectral imaging in the range of 713 - 920 nm can be used to classify oriental melons maturity and recognize their fruits.

  • 정부 3.0의 확산으로 공공 데이터의 활용요구가 증대되고 있으나, 정부가 보유하고 있는 공공데이터의 품질 및 관리체계는 아직 성숙화되어 있지 않아 데이터 개방 및 활용의 저해 요소로 부각되고 있다. 데이터 관리 및 연계 활용의 효과와 효율성을 향상시키기 위해서는 데이터 품질관리에 관한 표준 마련과 이를 평가할 수 있는 평가기준의 마련이 필요하며, 지속적인 품질관리가 이루어질 수 있도록 수준을 측정할 수 있는 체계의 마련이 필요하다. 본 연구는 공공데이터 품질관리 수준을 평가하고, 품질관리 수준을 지속적으로 판단할 수 있는 데이터 품질관리 성숙도 모델을 제시한다. 성숙도 모델은 프로세스 참조 모델과 측정 프레임워크로 구성하였다. 프로세스 참조 모델은 PDCA 기반의 15개 프로세스를 정립하였으며 이를 토대로 프로세스의 능력 수준과 데이터 품질관리 조직의 성숙도 수준을 평가하는 프레임워크를 마련하였다. 본 연구에서 제시한 성숙도 모델은 향후 공공기관이 보유하고 있는 데이터의 품질관리 현 수준을 진단하고 문제점을 개선하는 등 보유 공공데이터의 지속적인 품질향상을 위한 단계별 목표와 방향성을 수립하는 데 활용할 수 있으며, 궁극적으로는 공공데이터의 품질 신뢰도 향상을 통한 안정적인 공공데이터의 민간 개방을 촉진하고 이용을 활성화하는 데 적극 기여할 것으로 판단된다.

  • Assuming that the Capability Maturity Model Integration for Development v1.2 (CMMI) could be applied to an organization more effectively if the content similarities among practices were improved in terms of structure and composition, this paper presents the analysis of the correlations between the CMMI Specific Practices (SP) and Generic Practices (GP) for the Maturity Level 2 and 3 Process Areas using the Chi-square independence test. According to the analysis, a 22.2% correlation was observed. To minimize the problem of repeatedly applying similarities, 6 GPs that are highly correlated with the SPs were grouped together. Then, three different improvement plans: 1) development of a standard template-based project plan, 2) establishment of a configuration management system based on open source software to control work products and leverage experience, and 3) establishment of project assurance through an independent quality assurance-based organization and intensive review by higher-level management - were defined.
