For the purposed of improving the utilization of natural chemical pigment, carthamin, of Carthamus tinctorius, the effective extraction methods on this compound were pursued in the present study. The best solvent for the extraction was found to be the 1 %(v/v) NaOH solution, at 25 hours. In addition, more carthamin was extracted flowers from main stem than fromb-ranches . The carthamin content of Korean local safflower was shown to be higher than that of Japanese variety used for medicinal uses.

Purpose: The purposes of this study were to identify the actual conditions and needs of the health care utilization and health information in deafs. Methods: Forty-one deaf volunteers were interviewed by suwha nursing students. The semi-structured interviews were conducted in sign language at homes and community centers. The instrument developed by researchers consisted of 22 items including demographic information, health care utilization, and open-ended questions. Data were analyzed using content analysis, frequency and percentage. Results: The most discomfort problems were communication difficulty and expression of symptom. The deaf people wanted to learn about diseases and symptoms. The deaf wanted to get information about cancer. Conclusions: Further studies focusing on educational intervention are needed to increase the knowledge level on disease of deaf. The sign language translators are needed to help communication for deaf in health care facilities.

Purpose: With the advent of the era of the 4th industrial revolution, called a new technological revolution, the necessity of fostering future talents equipped with AI utilization capabilities is emerging. However, there is a lack of research on AI education design and competency-based education curriculum as education for business major. The purpose of this study is to design AI education to cultivate competency-oriented AI literacy for business major in universities. Research design, data and methodology: For the design of AI basic education in business major, three expert Delphi surveys were conducted, and a demand analysis and specialization strategy were established, and the reliability of the derived design contents was verified by reflecting the results. Results: As a result, the main competencies for cultivating AI literacy were data literacy, AI understanding and utilization, and the main detailed areas derived from this were data structure understanding and processing, visualization, web scraping, web crawling, public data utilization, and concept of machine learning and application. Conclusions: The educational design content derived through this study is expected to help establish the direction of competency-centered AI education in the future and increase the necessity and value of AI education by utilizing it based on the major field.

Finite element analysis (FEA) is an effective means for the analysis of bioelectromagnetism. It has been successfully applied to various problems over conventional methods such as boundary element analysis and finite difference analysis. However, its utilization has been limited due to the overwhelming computational load despite of its analytical power. We have previously developed a novel mesh generation scheme that produces FE meshes that are content-adaptive to given MR images. MRI content-adaptive FE meshes (cMeshes) represent the electrically conducting domain more effectively with far less number of nodes and elements, thus lessen the computational load. In general, the cMesh generation is affected by the quality of feature maps derived from MRI. In this study, we have tested various feature maps created based on the improved differential geometry measures for more effective cMesh head models. As performance indices, correlation coefficient (CC), root mean squared error (RMSE), relative error (RE), and the quality of cMesh triangle elements are used. The results show that there is a significant variation according to the characteristics of specific feature maps on cMesh generation, and offer additional choices of feature maps to yield more effective and efficient generation of cMeshes. We believe that cMeshes with specific and improved feature map generation schemes should be useful in the FEA of bioelectromagnetic problems.

This study was performed in order to measure consumed quantity of garlic and its content in each meal. Statistical data analysis was performed utilizing SAS package program. The results of this study can be summarized as followed ; 82% of foodservice surveyed has served garlic seasoned with soy sauce or vinegar etc. Kimchis was included in each meal in 98% of them and only 13.7% of them served Kimchis made by themselves. The Unit price of meal makes significant differences in the number of side dishes and the serving frequency of beverages and rice cakes. The content of garlic in meal were 2.6g in Soups, 2.9g in Stews, 1.9g in Namuls, 2.4g in Panbroiled foods, 3.0g in Hardboiled foods, 4.0g in Smothered dishes, 3.7g in Kimchis, respectively. Consumed garlic quantity makes significant differences by unit price of meal and consumption style of Kimchis(p<0.05).

The present study was conducted to investigate effects of rabbit meat extract on energy metabolism and muscle differentiation in C2C12 myotubes. Water extract of rabbit meat (10, 50, 100, and 200 ㎍/ml) was used to treat differentiated C2C12 cells. Reverse transcriptase polymerase chain reaction (RT-PCR) and western blot analysis were used to determine mRNA or protein levels of energy metabolism-related genes. Total adenosine triphosphate (ATP) content was also measured. Treatment with rabbit meat extract significantly increased expression levels of muscle differentiation markers (myogenin and myosin heavy chain) and mitochondrial biogenesis regulators (PGC1α, NRF1, and TFAM) in C2C12 myotubes compared to non-treated control. Additionally, rabbit meat extract activated phosphorylation of AMPK and acetyl-coA carboxylase (ACC). Rabbit meat extract significantly increased ATP contents in myotubes. These results suggest that rabbit meat extract has the potential to improve energy metabolism in skeletal muscles.

The domestic marine healing industry is undergoing significant revitalization efforts, with a focus on understanding the efficacy and effectiveness of marine healing resources. This study establishes utilization and management standards through a detailed analysis of the active components within well-recognized marine healing mud materials. Samples of mud materials were collected from domestic tidal flats. These samples exhibited an average composition of 7.87% sand, 74.95% silt, and 17.17% clay, with a combined mud content (silt+clay)(silt+clay) consistently exceeding 90%. Notably, SiO₂ emerged as the most prevalent effective ingredient at 68.4%, followed by Al₂O₃ (13.3%)>Fe₂O₃ (4.0%)>K₂O (2.9%)>Na₂O (2.3%)>MgO (1.6%)>CaO (1.0%)>TiO₂ (0.7%), in terms of average content. Subsequently, through an analysis of effective ingredients, Si, Al, Fe, K, Na, Mg, and Ca were identified as elements demonstrating significant functionality. Among these, key indicator ingredients were selected for quality control, all of which were found to possess efficacious properties. Notably, K, Mg, and Ca exhibited particularly high concentrations. Based on these findings and referencing existing literature, it is recommended that domestic tidal flat mud resources earmarked for utilization as marine healing resources should possess a raw material mud content of no less than 70.0%. Moreover, the cumulative index components K₂O+MgO+CaO should meet or exceed a threshold of 5.0% for optimal effectiveness.

In order to get basic information for utilization of yong leabes of medicinal herbs as vegetable, 7 species leaves of medicinal herbs were analyzed. The moisture content in 6 species leaves were 79.74 to 85.97%. The raw protein content were about 2% except Angelica gigas (1.12%) and Peucedanum japonica (1.27%). The raw fat were 0.96 to 1.36%, the raw fiber were 1.8 to 3.9% and the raw ash were 1.58 to 2.79%. There content of medicinal herbs were similar to general vegetables. The K contents were the highest among the medical components in all samples.
