In recent years, international cooperation has become important not only at the humanitarian level but also at the socio-economic level. As a result, major foreign countries are increasing capital-intensive international cooperation. In this environment, Korea needs to look for differentiated international cooperation plans centered on sustainable talent cultivation and move away from capital-based international cooperation. In this study, we analyzed the case of HRD (Human Resource Development) center in Cambodia as an international cooperation model between industry-academia-college for training software (SW) workforce. The HRD Center in Cambodia is an educational institution that fosters SW talent and can be viewed as an international cooperation model that can influence the ICT industry in Cambodia as an educational platform. In fact, 190 people who have been hired so far have entered various fields. 97% of graduates have been satisfied with HRD center and 90% of them are willing to recommend the center. In particular, as highlighted in the case study, the HRD Center has had a positive effect on not only cultivating self-initiated learning-based SW talent, but also formulating positive image of Korea and Korean companies thereby facilitating entry into the global market. The HRD Center in Cambodia has developed a virtuous cycle of fostering human resources, providing education, advancing industry and building a cooperative network. Korea has transformed into a platform for international cooperation and human resource development and education by providing active support and aid. This case study will be utilized as a new model of international cooperation with SW expert training platform for Korea.

In the previous study on the effectiveness of SW education, the educational goals were mainly focused on developing computational thinking ability and researching changes in computational thinking ability. But the word "computational thinking" is difficult to the public. Also the definition of computational thinking is varies from scholar to scholar. Therefore, this study aims to inform the public of the excellence and effectiveness of SW education through the change of "writing ability" which is more familiar to us. To achieve this goal, 10 lectures of SW training materials were produced and conducted in elementary science gifted class. As a result, significant changes have been made in the fluency and quality of writing skills, proving that SW training improves students' writing skills. Through this, we confirmed the visible results through SW education, which can be called justification of SW education. Furthermore, it is expected that various educational attempts will be developed using SW in other subjects.

Threats targeting cyberspace are becoming more intelligent and increasing day by day. To cope with such cyber threats, it is essential to improve the coping ability of system security officers. In this paper, we propose a stateful traffic generator that provide network background traffic for cyber warfare training. The proposed architecture is designed for generating traffic similar to real system traffic, so the trainee can perform more realistic training.

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.

LVC-G COTS SW are widely used for the military training due to several advantages. Accordingly, LVC-G COTS SW domestic developments are in demand. In this study, there are the four hypotheses in the gap between users and developers and establish the hypotheses are all correct. The first hypothesis "LVC-G associated with the COTS SW between users and developers about the requirements for the performance gap is expected.", the second hypothesis, "LVC-G associated with between users and developers for COTS SW technology gap is expected for the elements. ", the third hypothesis" LVC-G associated with the COTS SW development costs between users and developers about the expectations gap is about. ", the fourth hypothesis" LVC for COTS SW-G and related skill levels between users and developers are excited about the gap ". Every hypothesis were confirmed to be valid by interview and survey.

Semantic role labeling (SRL) is a task in natural-language processing with the aim of detecting predicates in the text, choosing their correct senses, identifying their associated arguments, and predicting the semantic roles of the arguments. Developing a high-performance SRL system for a domain requires manually annotated training data of large size in the same domain. However, such SRL training data of sufficient size is available only for a few domains. Constructing SRL training data for a new domain is very expensive. Therefore, domain adaptation in SRL can be regarded as an important problem. In this paper, we show that domain adaptation for SRL systems can achieve state-of-the-art performance when based on structural learning and exploiting a prior model approach. We provide experimental results with three different target domains showing that our method is effective even if training data of small size is available for the target domains. According to experimentations, our proposed method outperforms those of other research works by about 2% to 5% in F-score.

The purpose of this study was to develop and apply the elementary teacher training course for educational programming language based on TPACK in order to make elementary school teachers fully equipped with teaching efficacy for SW education. As a result, the informatics teaching efficacy of the teachers in the experimental group who participated in EPL training course developed based on TPACK was statistically more significant than the teachers in the control group(t=4.13, p<.001). The dependent sample t-test of the experimental group showed a statistically significant increase with t=4.57 (p< .001). It proved that TPACK-based teachers' training course is effective to improve teachers' informatics teaching efficacy. It is suggested that the development of SW education teacher training course should be systematically structured considering TPACK framework.

이 연구는 초등 교사를 대상으로 한 효율적인 연수 프로그램 구성의 출발점 자료를 확보하고자, 초등 교사 200명을 대상으로 SW 교육 영역(SW 문화, SW 창의, SW활용)의 소양 정도를 파악하고 영역 간의 관계를 분석하였다. 연구의 결과, SW 문화소양의 충족, 특히 SW 윤리 소양의 충족이 SW 창의교육 영역(컴퓨팅 사고력과 SW 제작 소양)에 큰 기여를 하는 것으로 확인되었다. 따라서 SW 교사 연수 효율성 제고를 위해 SW 윤리 영역이 컴퓨팅 사고력 영역 및 SW 제작 영역에 관한 교육 내용과 연계성 있는 배치와 시간 운영이 필요하겠다.

본 연구는 SW교육 기초연수를 수강하는 SW교육 초급교사의 SW교육 교수효능감을 측정하고, 그 현황을 파악하여 이를 바탕으로 수강자의 SW교육 교수효능감을 신장시킬 수 있는 연수를 기획 및 수행하는 기초자료를 마련하고자 수행되었다. 연구 결과 SW교육 기초연수에 참가한 교사의 SW교육 교수효능감 중에서 교사 자신의 교수능력에 대한 개인적 판단인 개인효능 영역에서 연령, SW교육 경험에 따라 큰 차이가 존재함을 확인할 수 있었다. 따라서 SW교육 기초연수에서 5년 미만의 저경력 또는 20년 이상의 고경력 교사와 SW교육 경험이 전혀 없는 교사의 개인효능을 향상할 수 있는 방법을 고민하고 이를 연수에 반영할 필요가 있다는 시사점을 도출하였다.

The purpose of this study is to examine teachers' stages of concern and levels of use about SW education based on Concerns-Based Adoption Model and to provide implications for teacher education. For this purpose, 152 survey responses were collected from elementary school teachers in South Korea. The result indicated that elementary school teachers' concerns about SW education showed the nonuser pattern in that teachers score highest in stage 0(awareness) to stage 2(personal) and in stage 6(refocusing). Additionally, teachers who are currently implementing SW education showed a tendency to be in the level of mechanical use or routine, and more than half of the teachers who are not implementing SW education showed no motivation to change current practices. There were statistically significant differences in the stages of concern depending on gender, teaching experience, SW training experience, SW teaching experience, and there were differences in the levels of use depending on the teachers' grade level in charge, SW training experience, and SW teaching experience. Based on the results of the research, various SW related programs as well as successful SW education experience for teachers need to be provided for teacher education in order to promote SW education.
