At public elementary schools in areas where multicultural students are concentrated, they have difficulty understanding classes due to their lack of Korean proficiency. Multicultural teaching and learning materials produced by teachers have not been managed or reused and stored individually. To overcome this situation and increase students' learning effect, the study applied digital curation to multicultural teaching and learning materials and suggested to link the materials with a platform that can be stored, used, and shared. The study was based on B Elementary School in A City, a multicultural international innovation school under the Gyeonggi Provincial Office of Education. The process of applying digital curation to multicultural teaching and learning materials was analyzed by collecting, organizing/selecting teaching and learning materials, categorizing subject, classifying subtopic, and linking with platforms. Practical issues and policy suggestions in school settings were also proposed.

With the increasing demand for wearable sensors that are capable of point-of-care testing, paper-based sensors have been extensively studied. Paper is not only extremely cost-effective but also lightweight and flexible, and it is easy to apply conductive materials such as carbon and hydrophobic substances like wax to its surface. Moreover, the capillary action caused by cellulose fibers in paper allows the flow of liquid without help from external forces, making paper a particularly promising platform for wearable electrochemical sensors. Accordingly, paper-based sensors for detecting various analytes through electrochemical methods have been actively developed. Recently, paper-based electrochemical sensors that utilize electrochemiluminescence (ECL) or electrochromic materials for the optical read-out have been reported. This review introduces the basic fabrication methods and various application strategies of paper-based electrochemical sensors.

Purpose: This study aimed to determine the influence of psychological factors such as highly sensitive person, intolerance of uncertainty, depression, and self-esteem on nurses' perceptions of gaslighting damage. Methods: The participants were 178 nurses working in hospitals nationwide. Data were collected through a non-face-to-face approach using an online survey platform (Google Forms) with self-reported questionnaires. Perceptions of gaslighting damage were measured using the victim gaslighting questionnaire (VGQ). The collected data were analyzed with statistical methods such as independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis using IBM SPSS 25.0. Results: Of the participants, 94.4% were female. The participants' average age was 32.7 years old, 60.2% were unmarried, and 86.0% were staff nurses. The mean score of the VGQ was 40.49. There were statistically significant differences in the VGQ according to marital status, participants' time in their current department, total clinical career, and type of medical institution. The perception of gaslighting damage was statistically significantly positively correlated with intolerance of uncertainty, highly sensitive person, depression, and self-esteem. The most influential factor on nurses' perception of gaslighting damage was intolerance of uncertainty (β=.32, p<.001), followed by depression (β=.30, p<.001) and highly sensitive person (β=.23, p=.001). The total explanation of these variables for the perception of gaslighting damage by nurses was about 75.0%. Conclusion: This study suggests that it is necessary to develop an intervention program to reduce negative psychological factors affecting gaslighting in nurses and to cultivate nurses' strength to overcome gaslighting damage.

In this paper, we present a 5W1H programming model for IT non-experienced people who are not familiar with computer programming and those who need programming education. Based on this model, we can design a development tool that can be easily programmed by beginners. This development tool is a programming method applying the 5W1H concept and constructs a sentence to satisfy the control condition of 'Who, When, Where, What, and How', which is the sentence element of 5W1H. Therefore, the user can easily develop the target system as if constructing the sentence without learning the programming language of the target system. In this paper, to verify the effectiveness of the 5W1H programming model proposed in this paper, we applied the concept of 5W1H programming to Arduino and developed the development tool and performed the first verification and applied the second verification to the speech recognition smart home development platform.

This paper presents an efficient interactive framework for perspective scene completion and editing tasks, which are available largely in the real world but rarely studied in the field of image completion. Considering that it is quite hard to extract perspective information from a single image, this work starts from a friendly and portable interactive platform to obtain the basic perspective data. Then, in order to make this interface less sensitive, easier and more flexible, a perspective-rectification based correction mechanism is proposed to iteratively update the locations of the initial points selected by users. At last, a complanate mesh is generated by the geometry calculations from these corrected initial positions. This mesh must approximate the perspective direction and the structure topology as much as possible so that the filling process can be conducted under the constraint of the perspective effects of the original image. Our experiments show the results with good qualities and performances, and also demonstrate the validity of our approaches by various perspective scenes and images.
