We suggest the C2 modeling method to develop a simulation model for training command groups which consist of commanders and staffs. By using C2 models in constructive simulation models, combat entities or units directly receive and execute orders from a command group without mediating human role players. We also compare combat results from suggested modeling method with the results of existing models by building and implementing a simulation model with C2 models. Our analysis by comparison demonstrates advantages of suggested method to model C2 for computer assisted exercises.

The purpose of this study is to develop a flipped-learning based education model for vocational education and training. Based on previous studies, we have developed a training model that includes definitions of flipped-learning, major learning activities, and operational strategies in each occupation. In addition, delphi surveys were carried out to confirm the validity of the educational model for HRD and vocational education and training specialists. Finally, the flipped-learning model for vocational education and training consists of three stages: Pre-learning, Main-learning, and Post-learning. Pre-learning stage include Online lectures, Simple tasks, Main-learning stage include Active learning and Coaching-Debriefing lecture, Post-learning stage includes Individual reflection-Additional task performance activities. The educational model developed through this study was developed with the focus on improving the linkage and the performance of the goal of vocational education and training.

As the "Partial Amendment to the Vocational Competency Development Act" was passed, and the mandatory refresher training was legislated in March 2020, HRD education institutions has prepared a plan for the improved refresher training to strengthen the competency of vocational training teachers and to improve the quality of refresher training. However, as demand for refresher training is concentrated in partial occupations, it is necessary prepare a separate plan to recognize personal learning as a refresher training for a minority of teachers who are not provided with a training. Therefore, this study aims to identify areas of a minor training occupations that don't exist many participants for a refresher training and to derive ways to recognize their multiple education experiences and participations instead of attending a refresher training. To this end, literature review, analysis of current situation, consultation with stakeholders, and written interviews with experts were conducted. As a result, a minority of training occupations was defined as type 1 and type 2 and ways of the recognition of refresher training for minority of training occupations which embrace various educational types were derived. Lastly, discussions and suggestions on the expansion of the scope of the recognition of refresher training for minority of training occupations were provided.

This paper investigated the effects of cooperative learning and individual learning in computer science education. Most works and projects are accomplished in groups in most IT companies in Korea. Thus, cooperative learning is one of the most important aspects that must be learned in schools. This research studies how students think of individual and cooperative learning. It also researches and analyzes how different learning methods would affect the learning effects with surveys and experiments, which were conducted during two consecutive semesters with students in a department of a computer related major at a university in Seoul. This research compares and analyzes the results after dividing the students in two groups based on the different learning methods.

In securities companies where corporate management performance is heavily dependent on the ability of salespeople, excellent sales-force with the ability to create high performance is very important. However, in the meantime, there was lack of studies on Private Banker's characteristics and sales behavior or sales performance. This study analyzed the effect of PB's characteristics on sales behavior in the Korean Securities Industry. The survey was conducted in March, 2013. 523 responses were used in the data analysis. As a result, PB's 4 characteristics- attitude to work, performance orientation, learning orientation, customer orientation- showed a positive impact on the sales behavior, and the organizational support showed positive moderating effect on this model. In this study, we reported that securities companies must reinforce training and self-development programs in order to improve the characteristics of the PB and to upgrade management performance. In particular, the securities has to rebuild organizational support system to improve the individual characteristics of the PB.

As the number of exchange in various fields between countries increases, the number of international conference increases. Many students study simultaneous interpretation due to the increased demand of simultaneous interpretation. Since simultaneous interpretation requires a lot of learning time, students majoring in translation perform the self learning. The paper based sight translation training system is a representative self learning method, but backtracking decreases the efficiency of self learning and it requires the help of the partner. To improve the learning efficiency, computer based sight translation training system has been proposed. However, since students uses the computer based sight translation training system only in a fixed area due to low mobility of computer, the utilization of the system decreases. In this paper, smart device based sight translation training system has been proposed to increase the utilization of the proposed system. Since smart device has lower computing capabilities than the computer, we have proposed algorithms to deal with the low performance. We implement and evaluate the functionalities of the proposed training system.

This study explores the effectiveness of various data preprocessing algorithms for improving subseasonal to seasonal (S2S) climate predictions from six climate forecast models and their Multi-Model Ensemble (MME) using a deep learning-based postprocessing model. A pipeline of data transformation algorithms was constructed to convert raw S2S prediction data into the training data processed with several statistical distribution. A dimensionality reduction algorithm for selecting features through rankings of correlation coefficients between the observed and the input data. The training model in the study was designed with TimeDistributed wrapper applied to all convolutional layers of U-Net: The TimeDistributed wrapper allows a U-Net convolutional layer to be directly applied to 5-dimensional time series data while maintaining the time axis of data, but every input should be at least 3D in U-Net. We found that Robust and Standard transformation algorithms are most suitable for improving S2S predictions. The dimensionality reduction based on feature selections did not significantly improve predictions of daily precipitation for six climate models and even worsened predictions of daily maximum and minimum temperatures. While deep learning-based postprocessing was also improved MME S2S precipitation predictions, it did not have a significant effect on temperature predictions, particularly for the lead time of weeks 1 and 2. Further research is needed to develop an optimal deep learning model for improving S2S temperature predictions by testing various models and parameters.

TPM program, which is a methodology for improving the management results through the management innovation activity of a company, has been widely introduced in the field of a service industry as well as a manufacturing industry. The main purpose of this study is to present the theoretical model by the relationship between active factors of TPM program and management results for a productivity increase, and to investigate the direct and indirect effects on the management of a company through a parametric study. A questionnaire survey of 300 companies that presently utilize the TPM program has been conducted. In order to verify the validity and the reliability of the contents of the questionnaire survey, a confirmatory factor analysis has been done. A frequency analysis has also been performed to examine the characteristics of the respondent. The factor analysis and the frequency analysis were done by using SAS Ver. 8.2, and the verification of a research model was done by using LISREL Ver. 8.52. The active factors of TPM in the research model consist of 'an independent preservation', 'an individual improvement', 'a planned reservation' and 'an education & training'. Among those active factors, the individual improvement and the education & training significantly influence on the facility efficiency and the organization and personnel management. The organization and personnel management has a greater influence on the management results. Therefore, the education and training for employes is most important for the improvement of the management results through TPM program, and the individual improvement activity is also important.

The purpose of this study is to analyze military combat training data to improve military operation and training methods and verify required military doctrine. We set the number of combat disabled enemies, which the individual combatants make using their weapons, as the response variable regarding offensive operations from scientific military training data of reinforced infantry battalion. Our response variable has more zero observations than would be allowed for by the traditional GLM such as Poisson regression. We used the zero-inflated regression and the hurdle regression for data analysis considering the over-dispersion and excessive zero observation problems. Our result can be utilized as an appropriate reference in order to verify a military doctrine for small units and analysis of various operational and tactical factors.
