Students must be familiar with clinical skills before starting clinical practice to ensure patients' safety and enable efficient learning. However, performance is mainly tested in the third or fourth years of medical school, and studies using the validity framework have not been reported in Korea. We analyzed the validity of a performance test conducted among second-year students classified into content, response process, internal structure, relationships with other variables, and consequences according to Messick's framework. As results of the analysis, content validity was secured by developing cases according to a pre-determined blueprint. The quality of the response process was controlled by training and calibrating raters. The internal structure showed that (1) reliability by generalizability theory was acceptable (coefficients of 0.724 and 0.786, respectively, for day 1 and day 2), and (2) the relevant domains had proper correlations, while the clinical performance examination (CPX) and objective structured clinical examination (OSCE) showed weaker relationships. OSCE/CPX scores were correlated with other variables, especially grade point average and oral structured exam scores. The consequences of this assessment were (1) making students learn clinical skills and study themselves, while causing too much stress for students due to lack of motivation; (2) reminding educators of the need to apply practical teaching methods and to give feedback on the test results; and (3) providing an opportunity for faculty to consider developing support programs. It is necessary to develop the blueprint more precisely according to students' level and to verify the validity of the response process with statistical methods.

Purpose: The purpose of the study is to understand the experiences of career exploration among nursing students during their clinical practice and to develop a theoretical framework for the career exploration process. Methods: From February 2 to 28, 2015, data were collected through focus group interviews from 24 participating fourth-year nursing students. The data were analyzed using grounded theory. Results: The central phenomenon of 'confusion between the ideal and the reality of nursing' occurred in contexts for various reasons of choosing one's major, nurses in the ideal, a vague fear of the field, arduous nursing assignments in the field, and severe adversity in the nursing field. Nursing students tried to deal with their confusion by using interaction strategies such as pursuing the intrinsic value of nursing, finding role models, trying to project oneself, and preparing for adapting to reality. The career exploration process in clinical practice was a voyage to discover the authentic nurse of the pre-registration nurse. Conclusion: This result shows that nursing students were to gain confidence in their career choices by finding the value of nursing and interacting with patients. Therefore, opportunities for learning experiences about interaction with patients and various positive experiences in clinical practice should be provided for nursing students.

Major countries in the world have established strategies for educating about artificial intelligence(AI) and with large investments are actively implementing these strategies. With this trend, domestic ministries have made efforts to establish national strategies to better educate students about AI. This paper presents the syllabus of AI classrooms which has been developed and presented to pre-service and in-service elementary school teachers for their use. In addition, the AI education tools they particularly preferred and their future plans for utilizing them in the elementary school classroom were investigated. Through this study, it was found that pre-service and in-service elementary school teachers strongly prefer lectures about AI education tools that can be immediately applied in the classroom, rather than learning about the theoretical basis of AI. At issue, however, is that the ability to utilize AI is usually based on a sufficient understanding of the theory. Thus, this paper suggests further study to identify better pedagogical practices to improve students' understanding the theoretical basis of AI.

Objectives: The purpose of this study was to develop and evaluate booklets and video clips to prevent children from picky eating. Methods: Based on a survey conducted on food preferences of preschool children aged 2 to 5 years, 14 kinds of less preferred vegetables were selected. Accordingly, educational videos, activity books, and teaching-learning guides were produced for preschool children using the 'food bridge' theory, and the educational materials were named "Friendly vegetables". Educational materials were distributed to childcare institutions, and their effectiveness was investigated for preschool children who were instructed on these materials once every 30 days from March to November, 2019. The children were examined for changes in their knowledge of names, colors, taste/texture, methods of cultivation, and preferences for vegetables before and after the instructional course. Results: The awareness of vegetables increased significantly in younger children and the picky eating group. When the assessment was carried out in terms of vegetable knowledge, it was observed that the younger the age or the pickier the in eating food, the more effective the education is compared to the counter part. The preference for vegetables also increased after the instruction compared to the pre-instruction period, but significant changes were seen only in the 2~3 year age group for boys and girls. Also, only the picky group of girls showed changes in preference. The children's average interest in the education materials was 3.85 points out of 5 points. Conclusions: Through this study, we have developed educational materials for standalone use in childcare facilities and confirmed that they have a significant effect on improving awareness and preferences related to vegetables. In summary, the younger the age or the pickier the child in eating food, the more effective the education. It is believed that additional education on mealtime guidance is needed which can alter the eating behavior of preschool children and improve their diet. It is proposed to widen the scope of use of the materials by collecting diverse opinions from child care teachers.

Low-light image enhancement is a key technique to overcome the quality degradation of photos taken under scotopic vision illumination conditions. The degradation includes low brightness, low contrast, and outstanding noise, which would seriously affect the vision of the human eye recognition ability and subsequent image processing. In this paper, we propose an approach based on deep learning and Retinex theory to enhance the low-light image, which includes image decomposition, illumination prediction, image reconstruction, and image optimization. The first three parts can reconstruct the enhanced image that suffers from low-resolution. To reduce the noise of the enhanced image and improve the image quality, a super-resolution algorithm based on the Laplacian pyramid network is introduced to optimize the image. The Laplacian pyramid network can improve the resolution of the enhanced image through multiple feature extraction and deconvolution operations. Furthermore, a combination loss function is explored in the network training stage to improve the efficiency of the algorithm. Extensive experiments and comprehensive evaluations demonstrate the strength of the proposed method, the result is closer to the real-world scene in lightness, color, and details. Besides, experiments also demonstrate that the proposed method with the single low-light image can achieve the same effect as multi-exposure image fusion algorithm and no ghost is introduced.

In this paper, we developed a design thinking-based artificial intelligence education program for middle school students and applied it to verify the impact on creative problem-solving skills. The inspection tool used the Creative Problem Solving Profile Inventory (CPSPI), an inspection tool for measuring creative thinking type ability based on the CPS theory of Hwasun Lee, Jungmin Pyo, Insoo Choe(2014). CPSPI included the steps of evaluating cognitive preferences and cognitive abilities by supplementing the limitations of existing tests, and sharing and persuading one's ideas with others. Before and after applying the design thinking-based artificial intelligence education program, as a result of analyzing the creative problem-solving ability, it increased significantly in all areas. As a result of analyzing the creative problem-solving ability of middle school students, significant results were found in the areas of Problem Detection and Analysis, Idea Generation, Action plan, Execution, Persuasion and Communication. The effect of design thinking was confirmed as a teaching and learning method to improve creative problem-solving ability in artificial intelligence education.
