In the SW education of non-majors who encounter liberal arts education experience difficulties in the SW development environment and understanding they encounter for the first time, relevance to their major, and convergence thinking ability. In order to compensate for the difficulties of non-major learners in liberal arts education, a relatively easily accessible software was used to utilize a demonstration-oriented model that can be applied to beginners in SW education. In order to understand the logical flow of applications and problem solving used in real life, we proposed a convergence SW teaching method that combines repeated implementation through demonstration by the instructor and imitation of the learner, and learning indicators to increase the learning satisfaction and achievement of the learner. In the experiment applying the teaching and learning method proposed in this paper, meaningful results were shown when evaluating the learning effect, academic achievement, learning satisfaction, and teaching and learning method aspects of SW education.

The analysis targeted the curriculum of general, subject education, and apecial activities that are required for SW education of 11 universities of education where SWEET project is applied. The results showed that the average credits related to SW education in elementary school teacher training institutions were 2.2 for general, 2.3 for subject education, and 0.6 for special activities. As a result of analyzing the changes in the curriculum by year, it can be interpreted as an effect of the SWEET project because the proportion of credits and hours in subject education increased and because the proportions of general and special activities decreased. However, on average, the credit related to SW education was 5.1, whereas the credits related to mathematics and science were 6.5 and 7.8, respectively, which indicated a need for revising and improving the curriculum for SW education.

Today is the era that the importance of education and training is emphasized. However, the problem of the issues on the question how the coding or related educations according to the 4th industrial revolution era are applied or utilized actually or that the correlation with the actual enterprises is facing with social and realistic problem. Therefore, this study intended to identify what impact the characteristics of the education and training has on the educational outcomes on the characteristics of individual by segmentalizing the characteristics of education and training, through which, this study examined what impact it has on the educational outcomes. As a result, it was shown that the SW education course has positive (+) impact on the major competence and learning performance out of the characteristics of individual and SW educational environment does not have nay impact. In addition, it was shown that the characteristics of individual have positive impact on all the satisfaction of educational outcomes and the negative impact on all the dissatisfaction of educational outcomes. These results emphasizes the importance of the SW educational course and SW education teaching and deemed to be results to make us to think about the SW educational environment again.

전기 자동차 에너지 시스템을 개발하기 위해서는 열 유체-전자기장 연성해석이 필요하다. 이를 위해 열 유체와 전자기장 각각의 해석에 특화된 패키지들을 사용하고, 이 패키지의 실험 결과를 저장 장치를 통해 주고받는다. 하지만 이는 저장장치 I/O 횟수를 늘려서 전체 계산 과정을 느리게 만들 수 있다. 데이터 교환을 MPI 패키지를 이용하여 DRAM 을 통해 이루어지도록 만들 수 있지만, 이는 계산 결과의 지속성을 악화시킨다. 즉, 열 유체 및 전자기장 연산과정에서 속도와 결과의 지속성은 상충적인 관계 갖는다. 본 연구는 이러한 관계를 실험적으로 분석하고 데이터의 지속성을 완화했을 때 이에 의해 얻을 수 있는 성능 이익을 분석한다.

Since the problem-based learning (PBL) shows the effectiveness of self-directed learning ability and internalization of learning motivation in the process of solving real problems, studies on PBL and application cases are actively pursued in the university education. This study analyzed the effects of PBL on the academic achievement and computational thinking in a non-SW major students' programming course. The programing course was divided into the PBL class and non-PBL class, and at the end of the classes, the scores of the exams and the results of questionnaires about the educational effectiveness and computational thinking were analyzed. As a result, the students in the PBL class, compared to those in the non-PBL class, showed significantly higher scores in the areas of the algorithm implementing skill, self-directed learning, problem solving ability, and continuous learning motivation.

This study analyzes the results of a survey based on classes conducted in the field to understand the educational needs of learners, and reflects the elements necessary for SW education. In this study, various experimental elements according to learning motivation and learning achievement were constructed and designed through previous studies. As a survey applied to this study, experimental elements in three categories: Faculty Competences(FC), Learner Competences(LC), and Educational Conditions(EC) were analyzed by primary area and secondary major, respectively. As a result of analyzing CT-based SW education by area, the development of educational materials, understanding of lectures, and teaching methods showed high satisfaction, while communication with students, difficulty of lectures, and the number of students were relatively low. The results of the analysis by major were found to be more difficult and less interesting in the humanities than in the engineering field. In this study, Based on these statistical results proposes the need for non-major SW education to improve into an interesting curriculum for effective liberal arts education in the future in terms of enhancing learners' problem-solving skills.

This article introduces a recent innovation in Korea's human resources development policy in the SW sector. Facing serious problems in cultivating SW engineers such as a mismatch in supply and demand of SW workers, shortage of globally competitive SW professionals, and insufficient education and training of university graduates, the Korean government has decided to adopt a new paradigm in national SW engineering education, based on supply chain management (SCM) in manufacturing. SCM has been a major component of the corporate competitive strategy, enhancing organizational productiveness and responsiveness in a highly competitive environment. It weighs improving competitiveness of the supply chain as a whole via long-term commitment to supply chain relationships and a cooperative, integrated approach to business processes. These characteristics of SCM are believed to provide insight into a more effective IT education and university-industry collaboration. On the basis of the SCM literature, a framework for industry-oriented SW human resources development is designed, and then applied in the case of nurturing computer-software engineers in Korea. This approach is expected to fumish valuable implications not only to Korean policy makers, but also to other countries making similar efforts to enhance the effectiveness and flexibility in human resources development. The construction of SCM-based SW HRD model is first trial to apply SCM into SW HRD field. The model is divided into three kinds of primary activities and two kinds of supportive activities in the field of value chain such as SW HRD Council, SW demand and supply plan establishment and the integration of SW engineering capabilities that contribute the reduction of the skill and job matching through SW HR demand and supply collaboration.

현재 지구촌은 신종 감염병인 '코로나바이러스 감염증-19(COVID-19)로 인해 혼란을 겪고 있다. 우리나라의 경우 1만 명 이상 감염자가 발생하였으며, 사망자 역시 200여 명이 넘었다. 하지만 위와 같은 감염병을 치료하기 위한 백신은 계속 개발중에 있으며, 현재는 감염 예방 수칙으로 감염의 위험성에서 벗어나고 있는 실정이다. 또, 지구촌에 큰 혼란을 주었던 사스, 신종플루, 메르스와 같이 주로 호흡기를 통해 타인에게 전파되는 신종 감염병 출현 빈도 역시 계속 증가하고 있다. 이외에는 황사, 미세먼지에 관한 문제들로 인해 일상속에서 이뤄지는 생활 방역의 중요성이 대두되고 있는 상황이다. 본 논문에서는 생활 방역의 대표적 수칙인 마스크 착용에서 상황별 올바른 마스크 선택의 중요성을 알려주어 시민의식을 높일 수 있는 VR 연동 'Wearing a Mask' 구현에 대해 제안하고자 한다.
