NFTs, which guarantee ownership of digital files using blockchain technology, are the new field for the content industry. The NFT provided new opportunities for content creators to trade digital contents without going through mediation freely. Additionally, collectors and investors can safely and easily own their works without the threat of illegal copies. However, since only a limited number of content creators are participating in the NFT market, there needs to be an influx of various content creators and a process of popularization for this market to grow and develop into the main stage. Furthermore, research on NFT has been limited, and understanding the drivers of creators choosing to participate in NFT is insufficient. Thus, this study aims to identify the factors affecting content creators participating in NFT by applying a mixed-methods approach and presenting practical implications. Using topic modeling and in-depth interviews, this study derives the positive and negative factors and suggests strategies to activate content creators' participation in the NFT market. Through this, we can guide that management implication to reduce the risks and costs of participating in NFTs is needed to encourage the participation of creators. It will also provide insight into ways to develop the NFT content market.

The purpose of this study was to create and validate Scale of Resilience to Burnout and Scale of Burnout Risk for social workers in medical settings. For the purpose, instrument development model, a kind of mixed methods research was used. In the first phase, six dimensions of resilience(: professional competency, accomplishment and worthwhileness, firm belief and value about their profession, good teamwork, support by their agency, and individual resources) and six dimensions of risk to burnout(: dissatisfaction with organizational condition, interpersonal stress among team members, organizational conflict, work related stress, deficiency of professionalism, and individual stress) were suggested thorough the preceding papers with qualitative approaches. The second phase involved analysis of a survey of 185 participants that appeared to validate the dimensions of the measures. The construct validity and reliability of each measure were tested. And it was founded that there were its own factors in each concept, although resilience to burnout related negatively to burnout risk. The results of this study suggest mixed methods research is useful to develop measures reflecting voices in the social work field.

In this study, we examined food intake, sodium intake, and satiety rate for different methods of consuming soup. Healthy young women (n=50) participated in this study. The subjects ate cooked rice and soup using a method that they preferred and then they were assigned into separate intake groups based on how they consumed their rice and soup. One group consisted of women that ate their soup and cooked rice separately (separate intake group, n=30). The second group consisted of the women who mixed the rice and the soup prior to consumption (mixed intake group, n=20). The mixed intake group consumed significantly more food (p<0.001) and sodium (p<0.05) than the separate intake group. Because of the high water content and ease of swallowing for the mixed intake method, the eating rate of the mixed intake group (42.5 g/min) was significantly higher than that of the separate intake group (28.8 g/min) (p<0.01). However, despite consuming 79.5 g more food at lunch, the rates of satiety were not significantly different before and after eating between the mixed intake and separate intake group. Therefore, eating rate, consumption norms and concept of "clean one's bowl" may influence food intake and sodium intake. Although more studies are needed, these data suggest eating cooked rice and soup separately may help to control obesity and hypertension.

This study was attempted to standardize preparation methods of Korean foods; Pibimbab (mixed rice) and Kongnamul Pibimbab (sprout mixed rice with soybean). We followed cooking method by using cookbooks, food service operation recipes , materials distributed by commercial food restaurants from their own experimental kitchens, and home recipes. Before those recipes were standardized, we thoroughly analyzed and modified. The total yield and portions were determined together with weights and procedures. And we evaluated food made by standardized recipes for acceptability by taste panels from Sookmyung Women's University. It concluded that yield volume for Pibimbab and Kongnamul Pibimbab after cooking for 10 persons was 6.5 kg, optimum service temperature was 7$0^{\circ}C$, preparation time was 6 hours, service volumes by one person was 650 g. This presentation for above on food materials and material weights, preparation methodsas well as cautions and references are attached in this research paper.

Purpose This study aims to identify user experience factors that can enhance both metaverse utilization and satisfaction based on the honeycomb model. For this we presented two research questions: first, what are the experience factors of metaverse users? Second, do metaverse user experience factors impact satisfaction? Design/methodology/approach To address these questions, a mixed-methodology approach is employed, including text mining techniques to analyze online reviews and quantitative econometric analysis to reveal the relationship between user experience factors and satisfaction. A total of 69,880 reviews and ratings data were collected. Findings The analysis revealed eight metaverse user experience factors: entertainment, operability, virtual reality, immersion, economic activity, visual performance, avatar, and sociality, all of which were found to have a positive impact on user satisfaction.

This study was conducted as part of a summer Korean language and culture program at a university in Korea, aimed at examining the changes in intercultural sensitivity among American students who participated in the program, as well as the Korean students who served as their language partners. The research utilized a mixed-method approach combining qualitative and quantitative analysis. To derive research findings, pre- and post-program Intercultural Sensitivity Scale surveys were administered to participating students and semi-structured interview data were collected from a randomly selected group of six students. The research findings indicated that among a total of twenty-seven students including both American and Korean students, significant changes in intercultural sensitivity were observed in the domain of Interaction Engagement. Furthermore, fourteen American students showed significant changes in their Interaction Confidence, while the Korean students who participated as language partners did not exhibit significant changes in the five subdomains of intercultural sensitivity.

The Communication Based Train Control(CBTC) System generally used to improving existing lines in the world is efficient and stable for improvement. Also it is efficient for improvement because it does not cause any problems in operation of existing lines. We examined the mixed operation scheme for more efficient and stable improvement when improvement is implemented depending on aged equipment and the increased number of passengers in the Korean city railroad. The biggest point in the mixed operation is to implement a stable test without interfering with the operation of the existing lines. For this purpose, we deduced a method of installing the equipment, a method of testing depending on the installed equipment, and the types of mixed operation, and presented a scheme of execution of the methods depending on the mixed operation.

Objective: This study examined five- to six-year-old children's categorization of mixed-race faces and how it was affected by perceptual individuation training (PIT) for other-races. Methods: Sixty-five children attending classes for 5-year-olds in childcare centers were shown happy and angry faces of Korean and African American mixed-race people, along with neutral faces of Korean and African American monoracial people. They were asked to categorize the faces into same-race or other-race. After the pretest, participants received a PIT for either African American (other-race) or monkeys. Then the racial categorization task was administered again as a posttest. Results: Children showed no general tendency to categorize mixed-race faces as out-group in the pretest. Yet, the PITs further reduced children's categorization of mixed-race faces as out-group. In particular, the effect was clearly evident in children who received the PIT for other-race. Conclusion/Implications: The results suggest that the tendency to categorize mixed-race faces as an out-group may not be evident in early childhood and that experiences of perceptually identifying other-race individuals may help children view mixed-race individuals as being in the ingroup, at least perceptually.
