Background: Ranavirus is an emerging infectious disease which has been linked to mass mortality events in various amphibian species. In this study, we document the first mass mortality event of an adult population of Dybowski's brown frogs (Rana dybowskii), in 2017, within a mountain valley in South Korea. Results: We confirmed the presence of ranavirus from all collected frogs (n = 22) via PCR and obtained the 500 bp major capsid protein (MCP) sequence from 13 individuals. The identified MCP sequence highly resembled Frog virus 3 (FV3) and was the same haplotype of a previously identified viral sequence collected from Huanren brown frog (R. huanrenensis) tadpoles in South Korea. Human habitat alteration, by recent erosion control works, may be partially responsible for this mass mortality event. Conclusion: We document the first mass mortality event in a wild Korean population of R. dybowskii. We also suggest, to determine if ranavirus infection is a threat to amphibians, government officials and researchers should develop continuous, country-wide, ranavirus monitoring programs of Korean amphibian populations.

In the intensely competitive global fashion market, the use of cultural elements to enhance design has become increasingly widespread. However, there is a lack of research on challenges and opportunities associated with integrating cultural elements of Minhwa into fashion design. Moreover, diverse approaches to incorporate Korean cultural elements into contemporary fashion designs are still needed. This study aims to reveal the real-world challenges relating to the incorporation of Korean cultural elements, including Minhwa, into fashion design and to clarify the possibility of applying Lin's cultural levels to cultural aspects in accordance with experts' views. To establish a theoretical foundation, the literature review on cultural design and Minhwa studies was conducted. It analyzes Minhwa to gain an understanding of the characteristics associated with different cultural levels. In-depth interviews with fashion industry professionals and Minhwa artists were conducted to ascertain their attitudes toward Minhwa use. The study's major findings were threefold. First, the cultural design facilitates the introduction, promotion, understanding, and maintenance of the culture. Since Minhwa offers rich inspiration linked to Korean culture, Minhwa-related designs can provide new perspectives while still having commercial potential. Second, however, the limitations of existing cultural designs included their being outdated, superficial without interpretation, unsophisticated, or limited. Furthermore, the use of Minhwa is limited since it is difficult to avoid creating superficial and unsophisticated designs in the real world. Third, approaching Minhwa at different cultural levels can promote diverse thinking and reduce the challenges of Minhwa use in design, but the major challenge remains visual expression.

Purpose: The purpose of this study was to investigate the relations among professionalism, organizational commitment and job satisfaction, and to the investigate the influencing factors of organizational commitment and job satisfaction among clinical nurses. Methods: The participants were 386 nurses sampled from Seoul and Gyeonggi provinces. A structured questionnaire was used to collect data, and the data were analyzed by applying t-test, ANOVA, Pearson correlation coefficient, and stepwise multiple regression with SAS 8.12. Results: A positive correlation existed among professionalism, organizational commitment and job satisfaction. Major factors that influenced organizational commitment were job satisfaction, religion, educational status, and a sense of calling (one of the subcategories of professionalism), which explained 54.1%. Major factors that affected job satisfaction were organizational commitment, educational status, and the subcategories of professionalism including a sense of calling, a service to the public, self-regulation and professional autonomy, which explained 60.8%. Conclusion: Based on the findings of this study, the professionalism is one of the critical factors linked to organizational commitment and job satisfaction among clinical nurses. In order to promote organizational commitment and job satisfaction among nurses, an appropriate practical support system, which is applicable to diverse conditions, should be developed and applied in nursing.

In recent times, STEM graduates are confronting a decline in employment rates influenced by economic, social, cultural, and policy-related factors. Career decisions are closely linked to education, college experiences, and university settings. To comprehend the reasons behind the decline in STEM employment, it is essential to explore the relationships among these factors. This study aims to comprehensively examine differences in career motivation and career exploration behavior among 2,393 STEM undergraduates in Korea. Additionally, factors affecting career motivation and career exploration behavior were investigated. The findings indicate significant differences in perceived career motivation and career exploration behavior based on individual backgrounds and university characteristics. And analyzing the data, 37.8% of career motivation is explained by contextual supports, career barriers, individual backgrounds (grade, GPA), university characteristics (major fields, location), field to enter after graduation, and timing of job preparation. For career exploration behavior, 30.1% is explained by contextual supports, career barriers, individual backgrounds (gender, grade, GPA), university characteristics (major field, location), field to enter after graduation, and timing of job preparation. Practical implications underscore the need for tailored educational and policy support, considering individual backgrounds and university characteristics, to effectively address challenges faced by STEM graduates in the evolving employment landscape.

A bioassay is a test system using a living organism (in whole or in part) to determine the presence or relative potency of chemical substances. The development and uses of bioassay are intimately linked to the discovery and characterization of the major classes of plant hormones. An application of this relationship is helpful for understanding the concept of plant hormones as well as the use of bioassay. And plant bioassay have been development and employed not only for the discovery and characterization of the biological activity of plant growth regulators but also have served several important secondary roles. The ideal bioassay should possess the characteristic of high specificity. great sensitivity. short response time, low cost and ease of obtaining plant material. acceptable ease of manipulation, and minimal space and equipment requirements.

Criticisms about amyloid cascade hypothesis of Alzheimer's disease(AD) are based on the findings, first, that the degree of dementia does not correlate with the number of plaques, and second, that the neurofibrillary tangle formation seems to predate plaque formation. In addition, neurofibrillary tangle counts correlate well with the degree of cognitive impairment. These findings suggest the independent importance of tau abnormality in AD research which is involved in the neurofibrillary tangle formation. Recently, tau pathology without amyloid deposits and mutations in tau protein gene were reported to be the major pathogenic mechanism in Pick's disease, progressive supranuclear palsy, corticobasal degeneration and FTDP-17(frontotemporal dementia and parkinsonism linked with chromosome 17). These data suggest that understanding the causes and consequences of tau dysfunction might give new clinical and therapeutic solutions to many known tauopathies.

Edestin, a major hempseed storage protein from Cheungsam, was isolated to apparent homogeneity by acid precipitation and gel filtration chromatography. The native molecular weight of purified edestin was approximately 300 kDa by Sephacryl S-300 gel filtration. Upon adding 2-mercaptoethanol, the isolated edestin of 56.7 kDa on the non-reduced sodium dodecyl sulfate polyacrylamide gel was converted into subunits, suggesting that the protein might be composed of subunits linked by disulfide bond. Cheungsam edestin was rich in essential amino acids and it has 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity. The results suggest that Cheungsam edestin might be utilized as a superior antioxidative nutrient.
