This experimental study was to examine the impact of collaborative learning in a virtual environment on students' learning outcomes and satisfaction. The collaborative virtual learning environment was created for a Korean history class for high school students. A total of 119 participants were recruited and were randomly assigned to either "collaborative group" or an "individual group." Students' academic achievements and satisfaction were collected as measurement tools to examine the effect of collaborative learning in the virtual learning environment and collected data were tested by independent sample t. The results showed that participation in collaborative groups had a significant positive effect on academic achievement and satisfaction than individual groups.

Since the 1990s, Korea has been developing various policies and materials for the improvement of basic learning abilities. In this study, the cases of policies for underachievers in Korea and the US were compared and analyzed the programs for mathematics underachievers in elementary school with Chuncheon office of education and Seattle public schools. All of them started from the point of relief of underachievers, but they differed in the process of operating them specifically. This study suggests the followings. First, active utilization of vacation programs to solve problems such as low-income meal service, prevention of stigma effects, securing teacher's instruction time, teacher-instructor cooperation. Second, the necessity of detailed activity-centered textbooks that underachievers can explore with interest in mathematics learning and easy to use by teachers. Third, specific cooperation for inducing interest of their own children's learning and forming close ties between parents and teachers. Fourth, program analysis by a professional evaluation group to improve the quality of underachiever program.

This study utilized SPSS and AMOS program to research a process of learning satisfaction of learners, who used Ubiquitous Living English Experience Learning Center. The following results were found ; First, there was a positive correlation between learning setting and learning interest, between learning setting and learning satisfaction, between confidence and learning interest, between confidence and learning satisfaction, and between learning interest and learning satisfaction. Second, the process of the research model was meaningful in various ways: learning setting ${\rightarrow}$ confidence, learning setting ${\rightarrow}$ learning interest, learning setting ${\rightarrow}$ learning satisfaction, confidence ${\rightarrow}$ learning satisfaction, learning interest ${\rightarrow}$ learning satisfaction. Finally, learning setting had a direct influence upon learning interest and learning satisfaction.

Although industrial complexes have played as an engine of the Korean economy for the last 40 years, the majority of industrial complexes shows limitations to the continuous growth such as a lack of innovation capabilities and social capital, conceived as a key to transforming into clusters of innovation. To overcome those problems, the Korean government embarked on the cluster policy from the mid 2000's, focusing on promoting the endogenous development capabilities of individual industrial complexes. Drawing upon the in-depth case study of the Gumi IT cluster, one of the representative large-scale industrial complexes in Korea, the authors conclude that the cluster policy has contributed to making the Gumi IT cluster enhance the capabilities of endogenous development through the facilitation of self-organizing learning communities within the cluster.

State-sponsored cyber attacks are highly impactful because they are carried out to achieve pre-planned goals. As a defender, it is difficult to respond to them because of the large scale of the attack and the possibility that unknown vulnerabilities may be exploited. In addition, overreacting can reduce the availability of users and cause business disruption. Therefore, there is a need for a response policy that can effectively defend against attacks while ensuring user availability. To solve this problem, this paper proposes a method to collect the number of processes and sessions of defense assets in real time and use them for learning. Using this method to learn reinforcement learning-based policies on a cyber attack simulator, the attack duration based on 100 time-steps was reduced by 27.9 time-steps and 3.1 time-steps for two attacker models, respectively, and the number of "restore" actions that impede user availability during the defense process was also reduced, resulting in an overall better policy.

This paper proposes a potential-based reinforcement learning, called "RLs-CBDT", which combines multiple RL agents and case-base decision theory designed for decision making in uncertain environment as an expert knowledge in RL. We empirically show that RLs-CBDT converges to an optimal policy faster than pre-existing RL algorithms through a Tetris experiment.

This paper is to illuminate the dynamic relationship between the technological learning mechanism and international political intervention. Besides conventional techno-economic factors, international political factors are emphasized as external factors in the technological learning mechanism. Being influenced by international political intervention, the evolutionary path of technological capabilities is not incrementally cumulated and organizational process is not autonomously performed, either. In order to mitigate the impact of the international political intervention, DCs make efforts to develop technological capabilities step-by-step in line with current and future civilian industrial demand.

교육은 준비, 발표, 적용, 복습 및 평가 순으로 이루어지고, 학습은 경험의 결과로 개인의 지각, 사고, 느낌, 행위의 방식에 의해 변화될 수 있다. 고로 초기 조종사를 양성하는 과정에서 교육과 학습은 안전문화 증진을 위한 매우 중요하다. 항공안전법에서 국내 조종사를 양성하기 위해 전문교육기관(ATO)을 국토교통부로부터 승인을 받아야 하고, 또한 항공안전관리시스템(SMS)도 승인받고 안전관리 활동이 의무화됐다. 조종사가 되기 위한 첫 관문인 학생조종사에게 국가 항공안전관리 정책 및 목표에 부합하도록 달성 가능한 수준의 항공 업무의 안전목표를 수립하고 그 구성원들이 학생조종사에게 안전문화를 형성할 수 있도록 효과적인 교육과 학습 방안을 마련해야 한다. 본 연구는 조종사양성 전문교육기관에서 교육을 받고 있는 학생조종사의 교육과 학습에 따른 단계별 안전의식을 알아보고, 학생조종사가 안전문화를 형성하는데 초기교육과 지속적인 교육을 통해 학습문화을 만들고 도움이 되는지 연구한다.

최근 비전통적 성인 학습자가 새로운 입학자원으로 주목받고 있으며, 그중에서도 만학도의 대학 진학률은 급격히 상승하는 추세다. 이에 따라 이들이 대학생활을 무사히 마칠 수 있도록, 즉 학업중단이 발생하지 않도록 대학에서는 다양한 측면에서 방안을 골몰해야 하는 상황이다. 본 연구는 이러한 문제의식에 기반하여, 비전통적 학습자의 학업중단을 저지할 방안을 창업지원 측면에서 살펴보고자 하였다. 이는 학업능력, 성별, 교우관계 등을 중점적으로 살펴보는 기존 연구에서 더 나아가 창업지원이라는 새로운 요인과의 관계성을 만학도의 입장에서 심층적으로 살펴봄으로써 연구의 차별성을 강조한다. 본 연구는 대학 입학 이후 학교의 창업지원을 받은 경험이 있는 만 30세 이상의 만학도 총 10명을 대상으로 심층인터뷰를 진행하여, 학교의 창업지원이 학업중단을 저지하는 데 영향을 주었는지를 살펴보고자 한다. 또한 그 과정에서 이들이 느낀 감정과 태도, 가치 등을 근거이론을 통해 분석하여 학업중단을 저지할 방안을 모색하고자 한다. 만학도는 전통적 학습자와 달리 졸업 이후 인생2모작을 준비하는 경우가 상당수기에, 이들의 니즈를 명확하게 파악하는 일은 시대적 흐름을 반영한 기초연구로서 학교의 정책적 대안을 마련하기 위한 기반이 될 수 있다.

Since Cyber Home Learning is an e-learning system promoted with policy goals of reducing private tutoring costs, solving gaps among regions, and improving scholastic attainments, preceding researches to verify its effects have been developed of evaluation standards focused on achievement of its policy goals rather than educational goals. The evaluation standards suggested in preceding researches have limitations in clearly reviewing Cyber Home Learning's effects by teaching-learning activities factors and Cyber Home Learning's improvement related to teaching-learning activities. Therefore, an evaluation model capable of analyzing effects of Cyber Home Learning from pedagogical aspect is required. The goal of this paper is to design pedagogical evaluation model according to teaching-learning activities factors and analyze effects of Cyber Home Learning. For the goal, researches from Korea and abroad related to Cyber Home Learning have been examined, pedagogical evaluation model was designed according to teaching-learning activities factors, and the model was then experimented through survey and in-depth interview on students who used Cyber Home Learning. It is expected that results of this paper can be used as a basic data to improve quality of Cyber Home Learning service for teaching-learning activities, and will contribute to establishment of more developmental Cyber Home Learning policy in the future.
