Furthermore, the study categorizes Hanbok research into six key areas: design and patterns, consumer behavior and tourism, literature reviews, case studies, education, and digital technologies. Notably, the multidisciplinary nature of Hanbok research includes growing interest in its fusion with digital technologies, such as virtual reality and the metaverse, suggesting future directions for digitalization and global presence. This research highlights Hanbok’s expanding significance in both traditional culture and modern contexts, positioning it as an important cultural icon in domestic and international markets. The study emphasizes the need for further exploration into under-explored areas, such as Hanbok’s role in global tourism and adaptation to digital environments. Practical applications include opportunities for the Hanbok industry to leverage digital platforms, cultural tourism, and personalized marketing strategies. This study provides a valuable foundation for future research on Hanbok’s global reception and continued development as a cultural and commercial asset.

This study investigates the cognitive characteristics and transition flow of team mental models in virtual reality environments (VRE) compared to Zoom-based collaboration during fashion design problem-solving processes. Using the VRE platform Spatial.io as a case study, the study examines how virtual reality technologies influence the formation of shared mental models among collaborators. The objective is to identify key cognitive features that VREs offer to support problem-solving in multidisciplinary fashion design collaborations. The study employed a comparative experimental design, involving professionals from fashion design, marketing, and production. Participants completed the design concept generation tasks in both VRE and Zoom environments, all interactions were recorded and coded, with the analysis focusing on cognitive transitions, verbal dynamics, and collaborative behavior patterns across both environments. The results reveal that VRE fosters higher frequencies of environmental interaction (EI-EI), cognitive integration (CIM-CI), and planning to execution transitions in team interactions (PP-PIM), forming multidirectional feedback loops. These features enhanced dynamic adaptation to environmental stimuli. In contrast, Zoom-based collaboration relied heavily on linear verbal communication, with fewer cognitive transitions and limited structural feedback loops, thereby reducing efficiency in idea evaluation and execution in team interaction. The study highlights the potential of VREs to transform collaborative practices in fashion design by enabling immersive and multidimensional interactions, contributing to advancing digital collaboration strategies in creative industries, with implications for education and interdisciplinary innovation.

Dust pollution has recently become a shared environmental issue for both China and South Korea. This paper reviews the progress of China-South Korea cooperation on dust pollution control since the establishment of diplomatic relations in 1992, covering developments and achievements in policy dialogue, technical exchanges, and joint research. Additionally, this paper highlights the issues and challenges in China-South Korea environmental cooperation, such as the impact of political and economic factors, insufficient cooperation mechanisms, and low levels of public engagement. Finally, with a view to the future, this paper proposes three policy recommendations to advance environmental cooperation between the two countries: 1) strengthening bilateral cooperation to enhance the sustainability of environmental policies; 2) improving multilateral cooperation mechanisms to promote technological innovation; and 3) encouraging public participation to build a diversified governance framework. Finally, it is recommended to further refine the public participation pathways in future cooperation, incorporating successful case studies, and to clarify the division of responsibilities among the stakeholders in the multilateral cooperation mechanism to enhance the feasibility of the collaboration.

The electronic structures of graphene nanoflakes (GNFs) were estimated for various shapes, sizes, symmetries, and edge configurations. The Hückel molecular orbital (HMO) method was employed as a convenient way of handling the variety of possible GNF structures, since its simplicity allows the rapid solution of large system problems, such as tailoring optoelectronic characteristics of molecule containing large number of carbon atoms. The HMO method yielded the electronic structures with respect to the energy state eigenvalues, with results comparable to those obtained by other approaches, such as the tightbinding method reported elsewhere. The analyses included the consideration of various types of edge configurations of 68 GNF systems grouped by their geometric shape, reflecting symmetry. It was inferred that GNFs in the small length scale regimes, below 1 nm, which are effectively small polycyclic aromatic hydrocarbon molecules, exhibit the optoelectronic characteristic of quantum dots. This is due to the widely spaced discrete energy states, together with large energy gaps between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). With increasing size this arrangement evolves into graphene-like ones, as revealed by the narrowing HOMO-LUMO gaps and decreasing energy differences between eigenstates. However, the changes in electronic structure are affected by the symmetries, which are related to the geometric shapes and edge configurations.

Strains of epiphytic and toxic dinoflagellates were collected from the seawaters surrounding Ulleungdo and Dokdo islands in Korea, and their morphology, molecular phylogeny, and toxicity were analyzed. Each dinoflagellate strain was examined under a microscope for genus-level identification, while species-level confirmation was achieved for Amphidinium operculatum, Ostreopsis sp. (type 1), Protoceratium reticulatum, Coolia canariensis, and C. malayensis through molecular phylogenetic analysis. The genera Gambierdiscus, Heterocapsa, and Prorocentrum were identified based on morphological traits, with Gambierdiscus characterized by a round-flattened shape with distinct thecal plates, Heterocapsa exhibiting a fusiform to oval shape, and Prorocentrum showing an oblong-to-ovate shape. Toxicity assessments for five species involved exposing Artemia salina nauplii to concentration-dependent extracts of the dinoflagellates. At a concentration of 100 ppm, P. reticulatum, A. operculatum, C. canariensis, and Ostreopsis sp. resulted in significant mortality among the nauplii, with survival rates dropping to as low as 0% over a 24-hour period. These findings underscore the potential ecological and toxicological impacts of these species and highlight the necessity for further research to evaluate their behavior under varying environmental conditions. This study marks the first documentation of subtropical epiphytic dinoflagellates in the waters around Ulleungdo and Dokdo islands, encompassing twelve strains from eight epiphytic species. Additionally, we investigated the toxicity of five species, including a toxic planktonic dinoflagellate. The results suggest a potential northeastward shift in their distribution, likely originating from Jeju Island, and being transported by the Tsushima Warm Current through the East Sea. This shift has enabled the successful establishment of populations in these areas under favorable conditions influenced by changes in the oceanic climate.

The Pieris napi-complex in East Asia that comprises P. melete Ménétriés, 1857, P. dulcinea (Butler 1882), and P. nesis (Fruhstorfer 1909) has been taxonomically challenging to distinguish due to their similar appearances. In this study, P. nesis, typically found in central Japan, was discovered in the highlands on Jejudo Island, the southernmost part of the Korean Peninsula. We conducted a molecular phylogenetic analysis using mitochondrial COI gene to explore the relationship between P. dulcinea and P. nesis, and confirmed that P. nesis occurs in Korea. This paper provides the morphological characteristics of P. nesis compared to P. dulcinea, along with DNA data.

As the pace of technological advances accelerates, the role of electrical energy storage has become increasingly important. Among various storage solutions, supercapacitors are garnering significant attention. Their unique attributes, including high power density, rapid charge/discharge capabilities, and extended lifecycle, position them as a promising alternative to conventional batteries. This study investigates the synthesis of a nickel oxide (NiO) and nickel oxide/graphene oxide (NiO/GO) composite using a single-step hydrothermal method, to evaluate their potential as supercapacitor electrode materials. The synthesized NiO, graphene oxide (GO), and NiO/GO composite were comprehensively characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy to analyze their crystal structures and chemical bonding. The XRD analysis confirmed the formation of an NiO phase with a rhombohedral crystal structure, and no change after GO incorporation. SEM analysis revealed the formation of spherical NiO particles and porous morphology of the NiO/GO composite, which also exhibited a spherical shape. The GO displayed a randomly arranged wrinkled sheet-like structure. Electrochemical analysis of the NiO/GO composite exhibited a remarkable specific capacitance of 893 F g-1 at a current density of 1 A g-1, surpassing that of NiO and GO alone, demonstrating NiO/GO has promising performance for supercapacitor applications. The charge transfer resistance, derived from the Nyquist plot, suggests that the reduction in charge transfer resistance contributed significantly to the improved capacitance. Additional stability studies of over 5,000 cycles at 5 A g-1 revealed an 85 % initial capacitance retention, confirming the advantages of GO inclusion to improve material retention for superior long-term performance. The asymmetric supercapacitor (ASC) assembled using an electrode with the configuration NiO/GO//activated carbon (AC) showed a specific capacitance of 77.8 F g-1 obtained at a current density of 0.5 A g-1.

We previously reported that pyridoxine and its derivatives exert antidiabetic effects by alleviating postprandial hyperglycemia via inhibition of carbohydrate-hydrolyzing enzymes in normal sprague–dawley (SD) rats. In this study, we aimed to further evaluate whether long-term pyridoxal supplementation decreases the blood glucose levels using SD rats. SD rats were randomly assigned to groups fed a high-carbohydrate diet (66.1% cornstarch) with or without pyridoxal (4%) for 36 days. Changes in body weight, blood glucose levels, and food intake were measured daily for 36 days. Dietary supplementation with pyridoxal significantly decreased the blood glucose levels (P<0.001) and body weight (P<0.001) in mice. Glycated hemoglobin (HbA1c) levels, which are good indicators of plasma glucose concentrations over prolonged periods, were also significantly decreased over five weeks (P<0.001). Similarly, dietary treatment with Acarbose ® (0.04%), a positive control, also significantly decreased the blood glucose and HbA1c levels and body weight. Overall, our findings suggest that pyridoxal inhibits weight gain and alleviates postprandial hyperglycemia by decreasing glucose absorption and HbA1c levels.

Hydrogen production via photoelectrochemical water splitting relies on the effectiveness of the photoelectrodes. Preparing low-dimensional structures of oxide semiconductors is a promising approach to fabricating effective photoelectrodes, by enhancing the surface-to-volume ratios of the photocatalytic materials. In this study, we performed a comparative investigation of the photoelectrochemical characteristics of p-type oxide semiconductor cupric oxide (CuO) photocathodes based on CuO thin film and nanorods. The CuO thin film was prepared via a facile method involving sputtering a Cu metallic film and subsequent thermal oxidation, while the CuO nanorods were grown via a seed-mediated hydrothermal synthesis method using a CuO nanoparticle seed layer. The structural, optical, and photoelectrochemical properties of the prepared CuO thin film and nanorods were comparatively examined. Our results confirmed that the CuO nanorod photocathode has a higher photocurrent density and better photoconversion efficiency than the CuO thin film photocathode for photoelectrochemical water splitting, implying a promising route to the fabrication of CuO-based photoelectrodes.

Current investigations provide a comprehensive understanding of the occurrence and biodiversity of plant-parasitic nematodes (PPNs) in the major citrusproducing regions of Jeju Island, South Korea. Our survey identified five genera and five species of PPNs from 82 infested Citrus unshiu field samples collected across 116 sites in the Jeju provinces. Community analysis revealed the highest prevalence of PPNs (39.02%) at Namwon-eup, significantly driven by Tylenchulus semipenetrans, followed by Paratylenchus sp., Helicotylenchus sp., Meloidogyne sp., and Pratylenchus sp. Data indicate that all 82 sites were infested with T. semipenetrans (70.68%), marking a considerable increase in prevalence compared to previous surveys and posing a significant threat to citrus cultivation. The study results also demonstrate the influence of soil type on PPNs communities, revealing correlations between soil texture and nematode diversity. Citrus orchards cultivated in black clay loam soil exhibited significant PPN infestations. Overall, the PPN survey underscores the economic importance of monitoring citrus nematode infection rates and maintaining economic threshold levels in citrus production. It also emphasizes the need for developing effective management strategies to control PPNs, which are essential for maintaining crop yield and ensuring agricultural sustainability.

Maturity at harvest is the key factor influencing storage life and the final quality of fruit. This study examined how the firmness of ‘Sweet Gold’ kiwifruit at harvest affects its post-ripening characteristics to create a maturity chart. Throughout the storage period, firmness decreased in all categories of fruit: hard, medium, and soft. ‘Soft’ fruits lost 40% of their firmness within 2 days after harvest, whereas ‘hard’ fruits remained firmer than soft fruits throughout the storage period and had the least soluble solids content, indicating a slower ripening progression. The acidity of ‘soft’ kiwifruit was very low from the day of harvest, suggesting that it was utilized as a respiratory substrate during ripening. The a-values (indicating redness) for ‘soft’ fruits gradually increased until day 6, stabilizing thereafter. ‘Soft’ fruits exhibited the highest ethylene production rate throughout storage. They showed a climacteric rise in ethylene on day 13, compared to ‘medium’ and ‘hard’ fruits, which exhibited increases on days 19 and 21, respectively. This data can help determine the optimal ethylene treatment duration for ripening ‘Sweet Gold’ kiwifruit. The firmness of ‘Sweet Gold’ kiwifruit at harvest is a crucial factor in determining its marketability and can effectively serve as a maturity index to estimate its shelf life.

Refractory materials, such as molybdenum and niobium, are potential candidates for cladding material due to their high melting temperatures and desirable mechanical properties at higher temperatures than those of zirconium alloys. However, refractory materials have low resistance to oxidation at elevated temperatures. Therefore, this study examined silicide or aluminide surface coatings as protection against rapid oxidation of refractory materials at elevated temperatures for a potential accident-tolerant fuel cladding. Silicide or aluminide layers were formed on refractory metal substrates by using the pack cementation method. The steam oxidation behavior of both coated and uncoated samples was compared by thermogravimetric analysis at 1200°C. The weight changes of the coated samples were greatly reduced than those of uncoated samples. Microstructural analyses demonstrated that the silicide and aluminide layers were oxidized to form a protective surface oxide that prevented rapid oxidation of the refractory substrate at elevated temperatures.

Two spider species of the genus Pholcus Walckenaer, 1805, Pholcus muju sp. nov. and Pholcus yeongheung sp. nov. in the family Pholcidae C. L. Koch, 1850 are newly described from Korea. These two new species belonging to phungiformes-group in the genus can be distinguished from their congeners by the shape and structure of genital organs of both males and females. They are found on rock walls in mountainous mixed forests. This work provides diagnoses, detailed descriptions, and taxonomic photographs for these new species.

Additive manufacturing makes it possible to improve the mechanical properties of alloys through segregation engineering of specific alloying elements into the dislocation cell structure. In this study, we investigated the mechanical and microstructural characteristics of CoNi-based medium-entropy alloys (MEAs), including the refractory alloying element Mo with a large atomic radius, manufactured via laser-powder bed fusion (L-PBF). In an analysis of the printability depending on the processing parameters, we achieved a high compressive yield strength up to 653 MPa in L-PBF for (CoNi)85Mo15 MEAs. However, severe residual stress remained at high-angle grain boundaries, and a brittle μ phase was precipitated at Mo-segregated dislocation cells. These resulted in hot-cracking behaviors in (CoNi)85Mo15 MEAs during L-PBF. These findings highlight the need for further research to adjust the Mo content and processing techniques to mitigate cracking behaviors in L-PBF-manufactured (CoNi)85Mo15 MEAs.

A study of intertidal habitats on Jejudo Island, Korea led to the identification of two new species, Desmoscolex (Desmoscolex) jejuensis sp. nov. and Desmoscolex (Desmoscolex) longispiculatus sp. nov., belonging to the subgenus Desmoscolex. Desmoscolex (D.) jejuensis sp. nov. is distinguished by the presence of 18 main rings, with males missing the 8th, 10th, and 14th subventral setae with the 2nd and 15th setae shifted laterally. In females, the 6th, 8th, 10th, and 14th subventral setae are absent. Conversely, D. (D.) longispiculatus sp. nov. exhibits 17 main rings with a typical somatic setae arrangement along with notably elongated spicules and the 14th and 15th subventral setae shifted laterally or slightly subdorsally. Both species are characterized by relatively long and slender cephalic setae. Detailed illustrations and high-magnification micrographs were produced using differential interference contrast (DIC) microscopy and scanning electron microscopy (SEM) to facilitate morphological comparisons between these new species and related taxa. Furthermore, a comparative trait table and a pictorial key are provided to clearly differentiate these new species from morphologically similar taxa. These findings contribute to the understanding of nematode biodiversity and contribute to the broader knowledge of Desmoscolex diversity in Korean coastal ecosystems.

According to previous studies, the El Niño Southern Oscillation (ENSO) does not appear to regulate TC activity over Korea. By dividing the TC season into two sub-seasons, i.e. summer and autumn, we found the opposite response of TC activity over Korea to ENSO phases between the sub-seasons. In summer, about 1.2 more TCs affect Korea during El Niño than during La Niña, while about 1.2 fewer TCs do so in autumn. The opposite responses to ENSO could reduce the statistical significance of the relationship between ENSO and TC activity over Korea when the entire TC season (July to October) is considered. In summer, the southerly anomaly over the southern sea of the Korean peninsula due to the eastward retreating subtropical high allows a greater number of TCs to approach Korea during El Niño compared to La Niña. On the other hand, in autumn, the northwesterly anomaly due to the westward extension of the subtropical high leads to a smaller number of TC approaches.

This study developed conductive inks composed of carbon black (CB) and silver nanowires (Ag NWs) for cost-effective screen-printing on fabrics. The Ag NW density within the CB matrix was precisely controlled, achieving tunable electrical conductivity with minimal Ag NW usage. The resulting inks were successfully patterned into shapes such as square grids and circles on textile surfaces, demonstrating excellent conductivity and fidelity. Adding 19.9 wt% Ag NWs reduced sheet resistance by ~92% compared to CB-only inks, highlighting the effectiveness and potential of this hybrid approach for cost-effective, high-performance textile-based electronics. The one-dimensional morphology of Ag NWs facilitated the formation of conductive percolation networks, creating efficient electron pathways within the CB matrix even at low loadings. This work advances the field of CB-based conductive inks and provides a scalable and practical method for producing functional, patterned electronic textiles.
