Recent studies have shown that inverse design using deep learning has the potential to rapidly generate the optimal design that satisfies the target performance without the need for iterative optimization processes. Unlike traditional methods, deep learning allows the network to rapidly generate a large number of solution candidates for the same objective after a single training, and enables the generation of diverse designs tailored to the objectives of inverse design. These inverse design techniques are expected to significantly enhance the efficiency and innovation of design processes in various fields such as aerospace, biology, medical, and engineering. We analyzes inverse design models that are mainly utilized in the nano and chemical fields, and proposes inverse design models based on supervised and unsupervised learning that can be applied to the engineering system. It is expected to present the possibility of effectively applying inverse design methodologies to the design optimization problem in the field of engineering according to each specific objective.

Recently, image analysis research has been actively conducted due to the accumulation of big image data and the development of deep learning. Image analytics research has different characteristics from other data such as data size, real-time, image quality diversity, structural complexity, and security issues. In addition, a large amount of data is required to effectively analyze images with deep-learning models. However, in many fields, the data that can be collected is limited, so there is a need for meta learning based image analysis technology that can effectively train models with a small amount of data. This paper presents a comprehensive survey of meta-learning-based object-tracking techniques. This approach comprehensively explores object tracking methods and research that can achieve high performance in data-limited situations, including key challenges and future directions. It provides useful information for researchers in the field and can provide insights into future research directions.

The aims of this study were to introduce cultural teaching procedures and propose cultural comparison activities as a practical method of cultural learning. It also analyzed learners' attitudes toward cultural learning through the aforementioned activities and examined considerations for holding cultural classes in the future. The research involved conducting a class underlain by four stages: warm-up, a cultural item comparison activity, wrap-up, and opinion submission. Data were collected through self-opinion journals and open-ended questionnaires, after which they were qualitatively analyzed. The results showed that the learners were highly satisfied with cultural learning through cultural comparison activities (73.7%) because of the efficiency of such a learning method, opportunities for proactive learning through interaction, increased interest and motivation, and the fact that it helps them understand their own cultures. We need to develop activities that enable learners to participate in a variety of ways through the mutual exchange of opinions when planning cultural classes. Pedagogical implications for integrated language and cultural classes are provided.

The purpose of this study was to investigate the elementary students' views about lab-based science learning. For the purpose of this study, semi-structured interviews were conducted with thirty sixth grade students in 12 classes from two elementary schools located in Daegu City. The interview contents consisted of three major categories. The first category was related to attitude toward science lab, the second was related to lab-based science learning which had four sub-categories; recognizing lesson object, planning experiment, performing experiment, drawing conclusion in lab-based science learning in which the students had ordinary have views and expectations, and the last category was related to students' difficulties and something need to be improved in lab-based science learning. In-depth interviews were performed individually and the interviews were recorded. From the interviews, we found that students, in first category, do like lab-activities more than lectures or instruction-based activities in textbook. Students, in second category, wanted generally more discussion for their own activities rather than teacher's instruction and they wanted teacher' mediation conflicts within small groups and comments for students' experiment results. In the last, most of students had fears for some dangerous reagents and accidents. Based on the results, the study suggested that teacher need to give their students to autonomous discussion opportunities to design and interpret data through teacher' guided questions in inquiry steps, to produce some intimate atmosphere for active interaction in small groups, and to teach the safety education on some dangerous reagents.
