Seafarers play an important role in shipping and logistics. However, seafarers are relatively vulnerable to mental illness because they have to board ships for a considerable period of time and work in isolation. In particular, in the pandemic situation caused by COVID-19, the crew change is delayed due to the closure of many ports around the world, increasing the mental burden on seafarers. The mental health management of the crew is important because these mental problems can lead to major accidents of lives and ships. This paper identified the necessity of mental health management of seafarers through a survey and identified problems with the currently operated mental health management program and curriculum. Especially, this study proposed VR-based programs to help crews receive mentally counseling treatment in a timely manner and to reduce the mental burden on them by preventing sensitive personal information exposure. Through this, it is expected to contribute to the stable development of the logistics industry by establishing a safe seafarers working environment.

Motor failure in manufacturing plays an important role in future A/S and reliability. Motor failure is detected by measuring sound, current, and vibration. For the data used in this paper, the sound of the car's side mirror motor gear box was used. Motor sound consists of three classes. Sound data is input to the network model through a conversion process through MelSpectrogram. In this paper, various methods were applied, such as data augmentation to improve the performance of classifying fault motors and various methods according to class imbalance were applied resampling, reweighting adjustment, change of loss function and representation learning and classification into two stages. In addition, the curriculum learning method and self-space learning method were compared through a total of five network models such as Bidirectional LSTM Attention, Convolutional Recurrent Neural Network, Multi-Head Attention, Bidirectional Temporal Convolution Network, and Convolution Neural Network, and the optimal configuration was found for motor sound classification.

The purpose of this study is to derive the roles of health care information managers in response to rapidly changing environments, analyze students' educational needs, and suggest ways to improve the curriculum of universities. A questionnaire was organized and a survey was conducted by deriving the roles of health care information managers based on the competency units presented in previous studies and NCS. As a result, first, it was found that there is a high need to improve medical information support, statistics generation and utilization, and regulation management in the current role. Second, for future roles, the priority of improvement for work process designers, clinical research coordinators, and business change managers was high. Reflecting these students' educational needs, universities need to establish an environmental basis for organic linkage of related subjects and step-by-step analysis and feedback efforts of instructors' training courses.

Countries around the world are strengthening informatics education to cope with the development of technology that leads to rapid social change. The last step in the capacity to foster through formal education is high school education. The purpose of this study is to examine the competence and level of informatics curriculum for high school students who aim to enter university in terms of testing tools. In order to carry out the research, we analyzed informatics education related test tools for high school students such as Japan, Germany, and USA. The results of the analysis are as follows: First, both the essay type and the short answer type question are included in the test tool as well as the multiple choice question type. Second, we use the real world model as an item and ask whether we can use computing power for practical problem solving ability. Third, the items directly related to the university education are reflected in the items. This study suggests that it has helped to elucidate the features and discussions of the test tool and establish the development direction of the test tool for informatics education.

The purpose of this study is to find ways to establish and operate Process-focused Assessment in the classroom as the 2015 revised curriculum has emerged. As a way of doing so, we proposed a Process-focused Assessment through self-assessment and looked at the impact of the applied classes on the mathematical academic performance and affective domain of fifth-grade elementary school students. After selecting two classes of fifth grade with proven homogeneity for research, the experimental group applied Process-focused Assessment through self-assessment and the teacher-led Process-focused Assessment to the comparative group. As a result, it was confirmed that the classes applying Process-focused Assessment through self-assessment significantly improved the math and academic performance of fifth-grade elementary school students. The affective domain of the experimental group did not change significantly, but the analysis of the students' comments and interview data showed that they had more interest and confidence in mathematics.

The purpose of this study was to analyse beginning science teachers' PCK. For the purpose of this study, two beginning science teachers were chosen in public middle school. Qualitative data were collected through classroom observation recording, semi-structured interviews, and other document data. Data were analysed using the constant comparative method. The results indicated that the two beginning science teachers' PCK had little differences; both have insufficient knowledge of science curriculum and assessment, and their PCK had quite differences in the instructional strategies and the orientations toward teaching science. Though they were aware of students' various levels, their common teaching method focused on delivery of science text knowledge for poor understanding about student. In conclusion, the two beginning teachers' PCK were still similar with preservice teachers. To develop beginning teachers' PCK, it needs to change the paradigm of pre-service teachers education program and to expand in-service teachers training and supporting program.

Education researchers have been continuously interested in the teacher's ability to design lessons and conducted various studies in order to improve the teacher's professionalism in determining the quality of school instruction. So, this study explored the change of instructional design through the lesson reflection of pre-service mathematics teachers who participated in practicum settings. As a result, in the lesson plan prepared by pre-service mathematics teachers, the motivation to induce learning in the introduction stage, to present the learning contents in the development stage, and to reconstruct the formative evaluation of the closing stage was the highest rate. And the categories of the reconstructed contents appeared intensively in terms of curriculum contents and teaching and learning methods. This result can be attributed to the lack of experience in designing and performing lessons by pre-service mathematics teachers, so it suggests that the opportunity to design and conduct classes that take into account the practical aspects of education should be provided in the preparation process for pre-service mathematics teachers.
