Ainsliaea acerifolia, a perennial herbaceous plant endemic to forested regions of the Korean Peninsula, has drawn attention for its bioactive properties and potential as a functional food and medicinal resource. Despite its ecological and economic value, little is known about its spatial distribution or habitat preferences under changing climatic conditions. This study aims to quantify the current and future habitat suitability of A. acerifolia in southeastern Korea—including Gyeongsangnam-do, Busan, and Ulsan—using the MaxEnt (Maximum Entropy) species distribution model. A total of 217 presence records were compiled from both GBIF data and field surveys, and seven key environmental variables were selected through multicollinearity screening. Model performance was robust (mean AUC = 0.845), and key predictors included topographic roughness (TRI), precipitation of the driest month (Bio14), and mean diurnal range (Bio2). Under current climate conditions, 31.5% of the study area was identified as suitable habitat (≥0.222), with only 4.7% categorized as core habitat (≥0.6). Future projections under SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios indicated substantial habitat contraction, particularly in coastal and lowland areas, with refugial zones likely to persist in mid-elevation inland mountains (500–900 m). These findings suggest that A. acerifolia is highly sensitive to climatic variability and emphasizes the urgent need for conservation strategies focused on climate-resilient refugia and ecological corridors. The study provides a spatial framework for species conservation planning under future climate uncertainty.

In this study, proteins were extracted from sesame and perilla meals (agricultural by-products) by using hot-water defatting and acid precipitation, and their functional properties were compared with those of a commercial soy protein isolate (SPI). According to the SDS-PAGE results, the sesame meal protein extract (SMPE) exhibited a higher content of hydrophobic amino acids than the perilla meal protein extract (PMPE), alongside a relatively lower intensity of the 7S globulin band. SMPE showed 1.41-fold higher solubility than SPI at pH 10 and 1.72- and 1.66-fold higher emulsifying activity indices (EAIs) at pH 8 and 10, respectively. PMPE exhibited similar trends in solubility and EAI as SPI at the corresponding pH values. However, the emulsifying stability indices of SMPE and PMPE were lower than that of SPI. In particular, the fat absorption capacity of SMPE was significantly higher than those of SPI and PMPE, likely because of its higher content of hydrophobic or nonpolar amino acid residues. These results suggest that SMPE and PMPE are promising alternative protein sources for food applications and may promote value-added utilization of plant-derived by-products in the food industry.

Ainsliaea acerifolia leaves are registered with the Ministry of Food and Drug Safety as edible herbal materials in Korea, and research is underway to explore their potential in developing functional foods, cosmetics, and pharmaceuticals. In this study, we developed an analytical method using HPLC-DAD to quantify three key compounds—chlorogenic acid, isochlorogenic acid A, and 1,5-dicaffeoylquinic acid—in A. acerifolia leaves extract. This method has been optimized and validated for specificity, accuracy, precision, limit of quantification (LOQ), and linearity. The correlation coefficients (r²) for the calibration curves exceeded 0.9962. The limits of detection (LOD) and quantification (LOQ) were 0.3012 and 0.9128 μg/mL for chlorogenic acid, 0.1182 and 0.3582 μg/mL for isochlorogenic acid A, and 0.2342 and 0.7098 μg/mL for 1,5-dicaffeoylquinic acid, respectively. The net recovery rates for accuracy testing were 105.13% for chlorogenic acid, 105.37% for isochlorogenic acid A, and 100.37% for 1,5-dicaffeoylquinic acid. All parameters assessed with this newly developed method fell within the acceptable ranges specified by ICH guidelines. These findings demonstrate that the method is robust and reliable for accurately identifying and quantifying chlorogenic acid, isochlorogenic acid A, and 1,5-dicaffeoylquinic acid in both routine analysis and large-scale extraction process of A. acerifolia leaves.

Although ethylformate and phosphine fumigants are widely used for pest quarantine, studies related to their mechanism of action and metabolic physiological changes in Drosophila models are still unclear. In this study, we investigated how key metabolites altered by fumigants and cold treatment are associated with and affect insect physiology by comparative metabolome analysis. Fumigant treatment significantly altered cytochrome P450 and glutathione metabolites involved in the detoxification mechanism and showed lower expression of PGF2α involved in the immune response compared to the control. Additionally, most of the metabolites functioned in metabolic pathways related to the biosynthesis of amino acids, nucleotides and cofactors.

The growth of OTT internet and mobile video streaming services is a major development in consumption of global media sport. The online streaming of sporting events has become the important way of copyrights holders to engage sport fans, especially young fans. The most popular live streaming platforms in South Korea, such as NAVER and Africa TV are intervening in coverage rights markets and changing how live sport is experienced and shared across television, computer, tablet and smartphone screens. At the FIFA World Cup Qatar 2022, NAVER's live streaming service reached 121,173,945 cumulative viewers in 64 matches, including the opening ceremony and the final between France and Argentina. Based on suspense theory, this study aimed to examine the factors that influence sport fans’ watching intention to stream online sport. The current study collected the number of cumulative viewers of live streaming from NAVER and Africa TV, for the matches broadcasted across the KBS, MBC, and SBS, a total of 64 matches in the FIFA World Cup Qatar 2022. The results suggest that a measure of the unfolding nature of suspense is a stronger predictor of watching intention than those used previously. The additional measures of suspense that take into account the unfolding events of the contest will be stronger predictors of watching intention than either disposition toward the winning team or closeness of final score.

In this study, we have fabricated the phenolic resin (PR)/polyacrylonitrile (PAN) blend-derived core-sheath nanostructured carbon nanofibers (CNFs) via one-pot solution electrospinning. The obtained core-sheath nanostructured carbon nanofibers were further treated by mixed salt activation process to develop the activated porous CNFs (CNF-A). Compared to pure PAN-based CNFs, the activated PR/PAN blend with PR 20% (CNF28-A)-derived core-sheath nanostructured CNFs showed enhanced specific capacitance of ~ 223 F g− 1 under a three-electrode configuration. Besides, the assembled symmetric CNF28-A//CNF28-A device possessed a specific capacitance of 76.7 F g− 1 at a current density of 1 A g− 1 and exhibited good stability of 111% after 5,000 galvanostatic charge/discharge (GCD) cycles, which verifies the outstanding long-term cycle stability of the device. Moreover, the fabricated supercapacitor device delivered an energy density of 8.63 Wh kg− 1 at a power density of 450 W kg− 1.
