In the future society where ICT-based digital convergence creates new value, collaborative skills among experts in various fields and SW based problem solving ability is more emphasized. Non-SW specialists are required to have SW based communication skills to effectively collaborate with SW experts to solve their problems. Therefore, SW programming curriculum for non-major college students should be different from the existing programming education for SW-majors aiming at a high level of coding ability. It is also known that diagram-based visual representation is helpful for productive communication and collaboration. In this study, we defined the SW education objectives for the non-majors as cultivating the visual programming ability for SW based problem solving. In order to accomplish this, we explored SW programming curriculum and content development model for non-majors focusing on visual representation of SW solutions. The results of this paper will help to provide appropriate SW learning model for non-majors and to cultivate practical SW capabilities.

As the weapon system SW development and management manual of the DAPA, which is the regulation for the overall weapon system SW development, is revised, the level and scope of SW reliability test are upgraded to improve the reliability and quality of SW. It is a big burden for SW developers. In particular, the dynamic test requires a schedule and manpower required to implement the weapon system SW, and should be performed every time the source code changes, not just one time. In this paper, we propose a regression test automation program(VectorCast Environment Manager) that performs a dynamic test using VectorCast, a dynamic test tool, and then performs a regression test automatically by minimizing human intervention in the regression test of dynamic test due to the change of the source code.

In this study, we reviewed the definition of completeness and payment in SW appraisal along to being complicated requirements of the appraisal, and we also presented their meaning and computation method. The completeness in SW appraisals means the degree of functional completion of the final product, and the payment refers cost spent to develop the product. Therefore, the completeness is evaluated based on the functions or interfaces of the final product, while the payment is calculated on the outputs or expenses of development steps. Recently, SW appraisal is complicated and the requirements for completeness and payment are changing. In this paper, we review the meanings and objectives of completeness and payment and present the evaluation methods for those.

상수관망 수리해석 기법은 절점의 사용량 및 누수량을 기지의 값으로 고려하여 총 수요량이 모두 공급될 수 있다고 가정하여 해석하는 수요기반해석(Demand Driven Analysis, DDA)과 사용량과 누수량은 절점 압력수두에 의해 달라질 수 있어, 공급가능량 및 누수량과 절점의 압력수두 모두를 미지수로 고려하여 해석하는 수압기반해석(Pressure Driven Analysis, PDA)으로 구분될 수 있다. 본 연구에서는 수압기반사용량 모의(Pressure Dependent Demand, PDD)와 수압기반누수량 모의(Pressure Dependent Leakage, PDL)기능이 모두 구현되고, 다양한 시나리오 분석이 가능한 소프트웨어(SW)인 K-NRisk를 개발하였다. K-NRisk는 2016년 7월에 공개된 상수관망 해석범용모형인 EPANET3 소스코드 기반으로 개량 개발되었으며, 기존 EPANET2와 비교하였을 경우 사용자 편의성 증대를 위한 입출력 기능 및 SW 활용도 제고를 위한 대표업무분석 기능이 신규 개발, 강화되었다. 개발된 SW를 관망정비 및 공급안정성 확보 목적을 위한 수리해석 시 적용하여 그 결과를 분석하였다. 적용결과 기존 수요기반해석이 가지고 있는 한계점을 보완하고, 실제업무 시 활용가능함을 확인하였다.

임베디드SW에 대한 개발이 활발히 수행되고 다양한 플랫폼에서 다른 임베디드SW와 통합되고 제어하는 다양한 요구사항이 발생하고 있으나 HW와의 밀접한 관계 및 재사용성의 요구를 반영하고 있지 못하므로 제품계열 개념을 적용한 접근이 필요하다. 따라서 임베디드 시스템 수명주기 및 시스템, HW, SW간의 관계를 통해 임베디드SW 개발절차를 도출하며, 제품계열 개발방법론 중에서 마르미-EM, FORM, FAST 및 KobrA를 선정하고 도출된 임베디드SW 개발절차와 비교하여 각 개발방법론의 절차상의 차이점, 강점 및 보완 사항을 분석하고 방법론별 특징을 종합한다.

This paper examines the complexity of recent SW development such as the 4th industry to apply the requirement engineering and redimimn application to the project to solve the difficulty of scope management during project management of medium and small businesses. These engineering techniques were applied to mid-sized and small-sized SW development projects. It was verified through supervision of 15 SW development projects. As a result, we observed about 30% reduction in related issues. In addition, Redmimn was introduced to SW development projects involving medium and small sized companies, and it proved that it has the effect of shortening delivery time through requirement management and tracking management. In order to secure the safety of the SW system development project, it is necessary to apply the required engineering techniques and tools, and it is necessary to continuously cultivate professional manpower to carry out this.

SW 기업들이 SW 프로세스 개선(Software Process Improvement; SPI)을 개선하기 위해 많은 관심과 노력을 투입해 왔음에도 불구하고, 이런 SW 프로세스 개선 활동이 품질, 비용, 납기준수에 어떠한 영향을 주는지에 대한 구체적인 자료들이 부족한 편이다. 본 연구에서는 SW 프로세스 개선활동들에 대한 이해의 폭을 넓히기 위해 국내 SW 개발 조직의 프로젝트 관리자를 대상으로 SW 프로세스의 공학수준과 DICE 수준관련 자료를 수집하였다. 이를 기반으로 SW 프로세스 개선 모델이 제시하고 있는 가정사항인 SW 프로세스 능력수준이 높으면 프로젝트 성과가 좋은지와 조직변화의 성공요인을 제시하는 DICE 수준에 따라 납기 성과의 변화를 살펴보았다. 분석결과 SW공학수준과 DICE 수준이 높을수록 납기가 줄어드는 것으로 나타났다.

The Goal of SW education is to cultivate creative and convergent human resources with computational thinking ability. The content and methods of SW education are diverse, and it is difficult for the students to properly evaluate what they have learned. In order to appropriately evaluate the learning contents, SW education evaluations should be able to easily evaluate the core content of the SW education. The purpose of this study is to provide a systematic framework that can be used to develop evaluation factors to evaluate the effectiveness of SW education in elementary and secondary schools. We conducted a literature review, a field suitability review through FGI, an expert consultation, and a Delphi survey. As a result, the metrics of the cognitive domain were developed with 17 keywords in three categories: Computational Materials & Outputs (CMO), Computational Concepts (CC), and Computational Practices (CP). Also, metrics of the affective domain were developed with 13 sub-areas in four categories: value, attitude, computational thinking efficacy, and interest. The SW education evaluation factors developed in this study can be used as a framework to develop the evaluation contents in accordance with the contents of education.

In this study, a SW interactive education training program for elementary school teachers was developed in order to cultivate the SW competency of teachers who apply SW education to schools, and the effect was analyzed by applying it to the school training site. For the development of the training program, the training development direction was set based on the current SW teacher training program, and an interactive training program was opened so that training could be conducted in a non-face-to-face situation in the COVID-19 situation. The developed training program was applied to 104 elementary school teachers in Gyeonggi-do. In order to analyze the effectiveness of the interactive training program, a survey on professor efficacy and satisfaction was conducted, and positive results were confirmed in terms of professor efficacy and program satisfaction. As it is expected that various SW/AI education training for teachers will be conducted as interactive training in the future, it is judged that it is necessary to conduct an analysis study on the effect of SW/AI training training.

In this paper, we propose an effective software education program to promote employment of the disabled and verify the effectiveness of SW education through pilot operation. In this SW education program, we develop a SW curriculum consisting of the basic course, Unity programming course, and the advanced course, AR/VR digital content development course. The SW education achievement standard develops the basic and advanced course achievement standards in consideration of the level of the virtual reality content production job of the National Competency Standards(NCS) and the SW education achievement standards of youth with visual, hearing, and physical disabilities. SW education materials are developed on a project basis so that one AR/VR digital content can be implemented step by step according to the intellectual level of the disabled based on Unity. SW education pilot training is conducted as online education based on Blended Learning due to COVID-19. In order to derive the SW education effect and each learner's individual SW education academic achievement for the SW education pilot training, a survey is conducted on learners, and the results are analyzed. In the basic course, 77.3% of learners achieved academic achievement above excellent(80-90), and in the advanced course, 48.8% of learners achieved academic achievement above excellent(80-90). These results verify that the SW education program for the disabled developed in this paper is effective in activating employment for the disabled.
