This study investigates activism as a powerful force for social and environmental change in South Asian fashion industries, specifically those in Pakistan, Bangladesh, and India. It defines the characteristics of fashion activism within regional contexts and explores the manifestation of fashion activism in a range of styles and practices. By combining a qualitative literature review with social media analysis, this study evaluates the role of activism in fashion and reveals that fashion serves as a vital medium for advocating social change while fostering a sense of community and identity among marginalized groups. The key findings indicate that social media is crucial for amplifying activist messages, encouraging stakeholder collaboration, and raising awareness regarding urgent social issues. In contrast to prior studies, which have primarily focused on a single topic, this research encompasses a comprehensive spectrum of activism within the fashion domain, examining critical themes such as cultural identity, gender equality, economic empowerment, and environmental justice. The findings suggest that fashion activism catalyzes significant transformations beyond conventional metrics, promoting a holistic framework for understanding social justice and sustainability. Furthermore, this study highlights the transformative potential of the fashion industry in driving social progress and emphasizes the need for further research to better understand these movements.

Maca has been reported to alleviate male menopause symptoms in humans and experimental animals; however, its mechanism of action in improving male menopause has not been clearly identified. This study aimed to investigate the mechanism of action of gelatinized maca in improving male menopause by analyzing serum testosterone, testicular androgen receptor (AR) expression, and testicular oxidation-antioxidation balance. Gelatinized maca was administered orally to aged male C57BL/6 mice at three doses (500, 1,000, and 1,500 mg/kg/day) for 28 consecutive days. Serum biochemical analysis showed an increase in serum hydroxysteroid 17-beta-dehydrogenase 13 (HSD17β13) concentration at 1,500 mg/kg/day and a decrease in serum sex hormone-binding globulin (SHBG) concentration at ≥ 1,000 mg/kg/day. Gelatinized maca administration also resulted in the increased expression levels of testicular AR and cyclic adenosine monophosphate (cAMP) response element binding protein (CREB) at 1,500 mg/kg/day. Oxidative stress analysis showed an increase in testicular superoxide dismutase and glutathione reductase activities and a decrease in testicular malondialdehyde at 1,500 mg/kg/day. In conclusion, gelatinized maca administration to aged male mice increased HSD17β13, AR and CREB expression, and antioxidant capacity and decreased serum SHBG. The results of the present study suggest that gelatinized maca may be a useful substance that can help alleviate male menopause symptoms.

Background: During daily activities, stability is maintained to enhance the function of muscles surrounding the lumbopelvic and hip structures. The core muscles such as the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) responsible for this stability. One effective static exercise for strengthening these muscles is the plank. Objects: This study aimed to compare abdominal electromyographic activation when an unstable support surface was applied to the upper and lower extremities during a standard and a knee plank. Methods: A total of 30 adults (15 males and 15 females) participated in this study. Surface electromyography electrodes were placed on the RA, EO, and IO muscles. Data were collected under six conditions for males, including two plank postures (standard and knee planks) and three unstable surface conditions (a dynamic balance cushion applied to the upper extremities, lower extremities, or no cushion). Female participants performed only the knee plank. A mixed-effects model with a random intercept was used to analyze muscle activation across plank posture and surface position, with statistical significance set at α = 0.05. Results: In males, the standard plank elicited greater muscle activation than the knee plank across all muscles (p < 0.0001). Additionally, applying an unstable support surface to the upper extremities significantly increased muscle activation in both plank postures in EO and IO (p < 0.001). Other muscle, RA, was only affected by the unstable support surface in the standard plank position only. In females, the knee plank with upper limb instability resulted in the highest muscle activation for all muscles. Conclusion: These findings highlight the importance of surface instability in core muscle engagement. However, future studies should further investigate abdominal muscle activation with a more detailed analysis and the inclusion of a control group to enhance comparative validity.

Sweetpotato (Ipomoea batatas L.) is a globally important food crop susceptible to root-knot nematode (Meloidogyne incognita) infection, which causes significant crop losses. Previous transcriptome and proteome analyses have identified several genes that show differential expression patterns in susceptible and resistant cultivars in response to root-knot nematode (RKN) infection. Among the genes responsive to this process, sporamin (SPO) genes were identified as the most abundant in the transcriptome analysis, and additional changes in the expression of SPO genes that showed specific responses to RKN infection were identified during nematode infection. In this study, we used SPO genes used in previous studies to identify expression patterns under various abiotic stress conditions. The expression of four SPO genes in sweetpotato leaves was investigated under conditions of drought, high salt, and stress-related chemicals treatment. The expression of G13675/TU22356, G34367/TU56356, and G34382/TU56395 increased similarly under dehydration and chemicals treatment conditions. On the other hand, G34367/TU56358 was constantly expressed during the stress treated conditions. This study is expected to be used as basic data on how the gene for the major protein SPO of sweetpotato responds to various abiotic stress conditions as well as nematode infection.

Background: Stroke often results in impaired postural control and asymmetric weight distribution, which negatively affect balance and functional mobility. Previous research has demonstrated that balance training interventions incorporating proprioceptive stimulation and visual feedback can enhance postural stability in stroke survivors. However, there remains debate regarding the relative effectiveness of these two approaches. While proprioception-based training emphasizes sensory input from mechanoreceptors to improve postural control, visual feedback-based training leverages external cues to facilitate balance adjustments. Objectives: To investigation the effects of proprioception-based trunk exercise and visual-auditory feedback-based trunk exercise on sitting balance in patients with chronic stroke. Design: Randomized controlled trial. Methods: A total of 24 participants diagnosed with chronic stroke were randomly assigned to two groups: the proprioception-based trunk exercise group (PTG, n=10) and the visual-auditory feedback-based trunk exercise group (VTG, n=11). Both groups participated in a 6-week intervention program, five sessions per week, lasting 25 minutes per session. Outcome measures included the Limitation of Stability (LOS), the Korean version of the Trunk Impairment Scale (K-TIS), and the Postural Assessment Scale for Stroke (PASS). Pre- and post-intervention assessments were analyzed using paired t-tests and independent t-tests to evaluate within-group and between-group differences. Results: Both PTG and VTG groups demonstrated significant improvements in LOS, K-TIS, and PASS scores following the intervention (P<.05). However, there were no statistically significant differences between the two groups in the amount of change observed. Conclusion: The findings suggest that both proprioception-based and visualauditory feedback-based trunk exercises are effective in improving sitting balance in chronic stroke patients. The lack of a significant difference between the groups indicates that both approaches provide comparable benefits. Future research should explore long-term effects and investigate potential differences in various functional domains beyond sitting balance.

Background: Neck discomfort and movement limitations are common musculoskeletal problems among modern people. While cervical and thoracic joint mobilization are widely used interventions for cervical dysfunction, research comparing their immediate effectiveness in adults with asymmetrical cervical rotation is limited. Objectives: To compare the immediate effects of cervical versus thoracic joint mobilization in adults with adults with asymmetrical cervical rotation and discomfort. Design: Randomized controlled trial. Methods: Thirty adults with left-right differences in cervical rotation of more than 5 degrees were randomly assigned to a cervical mobilization group (CMG, n=15) or thoracic mobilization group (TMG, n=15). Both groups received Grade III mobilization for 15 minutes. Range of motion (ROM), pain (VAS), and neck disability index (NDI) were measured before and after intervention. Results: Both groups showed significant increases in ROM after intervention (P<.001). Within-group analysis revealed that the TMG showed significant pain reduction (P<.01) and significant reduction in left-right rotation asymmetry (P<.001), while the CMG showed improvement in ROM but no significant changes in asymmetry or pain (P>.05). Neither group showed significant changes in NDI. Between-group comparisons showed no significant differences in any outcome measures. Conclusion: Both cervical and thoracic joint mobilization increased cervical range of motion in adults with asymmetrical cervical rotation discomfort. The TMG demonstrated significant within-group improvements in left-right rotation asymmetry and pain reduction, suggesting potential clinical benefits of thoracic mobilization for certain aspects of cervical dysfunction.

Background: Functional sarcopenia, a subcategory of sarcopenia, has recently been introduced. It is defined by muscle weakness and reduced physical performance, regardless of muscle mass reduction, and may potentially affect overall rehabilitation outcomes in patients. Objectives: This study aimed to classify stroke patients into two groups based on the presence or absence of functional sarcopenia and to compare changes in balance and gait ability after receiving the same rehabilitation intervention. Design: A quasi-experimental design. Methods: A total of 44 stroke patients participated in this study and were classified into functional sarcopenia (n=22) and non-functional sarcopenia groups. Physical function tests were used to assess balance (Timed Up and Go, Berg Balance Scale) and gait (10-Meter Walk Test, Functional Ambulation Category). All participants underwent a four-week convalescent rehabilitation program, receiving five sessions per week, with each session lasting four hours per day. Results: After four weeks of convalescent rehabilitation, both groups showed significant improvements in all outcome measures (P<.05). However, when comparing the pre-post changes, no significant differences were found between the two groups in the changes of balance and gait outcomes (P>.05). Conclusion: These findings suggest that stroke patients with functional sarcopenia can achieve a similar level of functional recovery as those without functional sarcopenia when provided with appropriate rehabilitation interventions.

Background: Prolonged use of computers and mobile devices has contributed to postural abnormalities such as Rounded Shoulder Posture (RSP), which is characterized by muscle imbalances that can lead to pain and functional limitations. Correcting these imbalances through targeted stretching and strengthening exercises was expected to help improve postural alignment and muscle function. Objectives: This study aimed to investigate the effects of a six-week integrated exercise program targeting the pectoralis minor (PM), upper trapezius (UT), and lower trapezius (LT) on postural alignment and muscle activation in female adults with RSP. Design: Single-group pre-post test study. Methods: Eighteen female university students (aged 20–22 years) with RSP participated in a six-week intervention consisting of PM stretching, UT stretching, and LT strengthening exercises. RSP severity was assessed using acromion-to-ground distance, PM length was measured with a caliper, and surface electromyography (sEMG) was used to evaluate UT and LT muscle activity. Normality was verified using the Shapiro-Wilk test, and paired t-tests were conducted for statistical analysis (α=0.05). Results: After the intervention, significant improvements were observed in all measured variables. Acromion-to-ground distance decreased (P<0.001), PM length increased (P<0.001), UT activation decreased (P<0.01), and LT activation increased (P<0.01). Conclusion: The six-week integrated exercise program effectively improved postural alignment and muscle activation in women with RSP by addressing muscle shortening, overactivity, and weakness. These findings suggest that combined stretching and strengthening exercises can serve as a practical and effective approach for RSP correction. Future studies with longer durations and diverse populations are recommended to further validate these results and enhance clinical applicability.

The corrosivity of molten salt presents a major challenge for the commercialization of molten salt reactors, which utilize molten salt as both fuel and coolant. To protect structural materials of molten salt reactors, minimizing moisture—the primary source of corrosion—is crucial, necessitating precise moisture concentration measurements. This study examines the role of an inert gas atmosphere in analyzing moisture in molten chloride salts. Four chloride salts with different hygroscopic properties (NaCl, KCl, MgCl2 and ZnCl2) were tested. Each was analyzed in three states: as-received and dried by heating for 6 and 12 hours. Karl Fischer titration was employed to measure the moisture concentrations in salts under both air and an argon-filled glove box. Results showed consistently lower and more stable moisture concentrations in the inert atmosphere, highlighting the necessity of an argon environment for accurate moisture analysis in molten salts.

The present study investigates the use of generative artificial intelligence (AI) tools by pre-service teachers (PSTs) in lesson planning for a middle-school English as a foreign language (EFL) class, aiming to address gaps and inform teacher training. The case study examined PSTs in a South Korean university course who were tasked with creating lesson plans using generative AI to aid in lesson plan development for a middle school lesson that incorporated generative AI. Data were analyzed thematically, and results revealed that generative AI was used in topic selection, material creation, lesson organization, and language checking. While generative AI facilitated efficiency and creativity, challenges emerged, including the quality of outputs and limited incorporation of effective pedagogical strategies. These findings indicate a need for targeted training in prompt engineering, ethical considerations, pedagogy, and collaborative practices to enhance PSTs’ generative AI competencies. This study contributes to teacher education programs by providing insights into the practical integration of generative AI in pedagogical practices.

A new spider species of the genus Pholcus Walckenaer, 1805, Pholcus osaek sp. nov., in the family Pholcidae C.L. Koch, 1850, is described from Korea. This new species belongs to phungiformes-group in the genus. It can be distinguished from its congeners by the shape and structure of genital organs of both males and females. It is found on and between rock walls in mountainous mixed forests. Additionally, the taxonomic status of Pholcus uksuensis Kim & Ye, 2014 is revalidated, re-diagnosed, and redescribed based on specimens collected from the type locality. Considering differences mentioned in the diagnosis through revalidation, P. uksuensis is regarded as a distinct species. Therefore, it should be removed from the synonymy of P. woongil Huber, 2011.

The efficient fabrication of uranium-based liquid fuels and the structural integrity of reactor materials are critical challenges for the deployment of chloride-based molten salt reactors (MSRs). As part of KAERI’s ongoing MSR development, this study investigates an optimized uranium chlorination process and a corrosion assessment of candidate structural materials under conditions more closely resembling actual reactor cores. To enhance process efficiency and scalability, metallic uranium was converted into uranium trihydride (UH3) via hydriding, achieving 34.1% efficiency. UH3 was chlorinated with ammonium chloride (NH4Cl), yielding uranium trichloride (UCl3) with a conversion rate over 98% and purity above 99%, as confirmed by ICP-OES. The UCl3 was used to fabricate various uranium-based liquid fuels for MSR applications. Simultaneously, the corrosion behavior of SS304, SS316, and Hastelloy-N was evaluated using a natural convection loop filled with a NaCl– MgCl2 eutectic salt mixture. The system operated for 500 hours at 500–580°C to replicate MSR conditions. Corrosion analysis revealed that SS304 suffered severe degradation, SS316 showed moderate resistance, and Hastelloy-N demonstrated superior stability, although some cold leg samples experienced mass gain due to corrosion product deposition. These findings provide key insights into optimizing liquid fuel synthesis and selecting corrosion-resistant materials for safe, long-term MSR operation.

This study was conducted to investigate the effects of feeding DDGS and full-fat soybean in the finishing diet on the performance, carcass characteristics and unsaturated fatty acid composition of Hanwoo steers. Thirty Hanwoo steers (average age, 26.4 months; weight, 756.69 kg) were assigned into Control (no additive), DS (DDGS supplemented) and FS (full-fat soybean supplemented). The feeding rate of DDGS and full-fat soybean was set at 10% and 5% in the finishing diet, respectively, and the in vivo trial was conducted for 122 days. The final body weight was 779.81, 774.20 and 791.95 kg for Control, DS and FS, respectively, and the average daily gain was not different among treatments. The feed conversion ratio was lower in FS compared to Control. Carcass cold carcass weight, backfat thickness, M. longissimus dorsi area and marbling scores were not different among treatments, and moisture, crude protein, and crude fat content in carcass were not different. The melting point of sirloin ranged from 25 to 26℃ among treatments. The saturated fatty acid, C18:0, was lower in the FS than in Control. C18:1, the main unsaturated fatty acid (UFA) in carcasses, did not show any difference among treatments, but C18:2 was higher in DS than in Control. Total UFAs were higher in the FS than in Control. Based on the above results, DDGS feeding was effective in improving feed conversion ratio and C18:2 content, and full-fat soybean feeding was effective in improving feed conversion ratio and increasing UFA content.

This study assessed the effects of fescue toxicosis on ruminal metabolism and physiology in steers. Twelve ruminally cannulated Angus steers [body weight (BW) = 547 ± 9 kg] were blocked by BW and randomly assigned to six blocks. The steers were fed alfalfa cubes (1.5× NEm) and dosed (1 kg/d) with either endophyte-infected tall fescue seed (E+) or endophyte-free tall fescue seed (E-) via rumen cannula for 21 days. Ruminal dry matter (DM) content was tended to have a higher (p=0.052) in steers in E+ than in E- group. Total volatile fatty acid (VFA), acetate concentrations, as well as the acetate:propionate ratio, were higher (p=0.084, 0.095, and <0.001, respectively) in the E+ group, while propionate was lower (p<0.001). Ruminal pH and temperature were similar between treatment groups (p=0.62 and 0.95, respectively), but ruminal pressure was higher (p<0.001) in E-. Additionally, serum prolactin levels was lower (p<0.001) in the E+ group. These findings suggest that consumption of endophyte-infected tall fescue seed may impair ruminal VFA absorption, potentially due to changes in ruminal motility.

This study conducted to investigate potential differences in the activity of genes involved in volatile fatty acid (VFA) absorption, pH regulation, and energy metabolism in epithelial cells of forestomach administered either endophyte-infected (E+; 4.45 mg ergovaline/kg) or endophyte-free (E−) tall fescue seed. Twelve steers [body weight (BW) = 547 ± 9 kg] were fed alfalfa cubes at 1.5 × NEm and dosed 1 kg of ground tall fescue seed daily via rumen cannula for 21 days. On day 22, steers were slaughtered, and tissue samples were collected from the rumen, reticulum, omasum, and abomasum. Gene expression analysis revealed that monocarboxylate transporters (MCT), isoform 1 and MCT4 expression levels were significantly lower (p<0.05) in the rumen epithelium of steers dosed with E+ seed, while MCT2 expression remained unchanged. Similarly, sodium hydrogen exchanger (NHE), isoform 2 expression was significantly reduced (p<0.05) in the E+ seed, whereas NHE1 and NHE3 were unaffected by the seed treatment. Additionally, expression levels of down regulated in adenoma (DRA) and anion exchanger (AE), isoform 2 were lower (p<0.05) in the rumen epithelium of E+ steers, while putative anion transporter 1, sodium bicarbonate cotransporter, isoform 1, 3-hydroxy 3-methylglutaryl coenzyme A synthase, isoform 2, and sodium potassium ATPase pump, isoform 1 expression levels were not influenced by the seed treatment. Notably, gene expression in the reticulum, omasum, and abomasum epithelia was unaffected (p>0.05) by seed exposure. These findings suggest that endophyte-infected tall fescue seed may impair ruminal VFA absorption in its dissociated state (pH > 5.8) by downregulating MCT1 and MCT4, along with suppressing NHE2, DRA, and AE2. Therefore, this mechanism may partially explain the reduced weight gain associated with fescue toxicosis in cattle.

This study aimed to evaluate the effects of different feeding levels of domesticated barnyard millet and imported Bermuda hay on the growth performance and structural development of female and male growing goats. A 4×4 Latin square design was used, involving 8 goats with an average age of 3 months: 4 females and males with an initial body weight (BW) of 10.6 kg and 16.0 kg, respectively. Goats were randomly assigned to 4 dietary treatments: T1 (1.5% BW barnyard millet), T2 (1.5% BW Bermuda hay), T3 (2.0% BW barnyard millet), and T4 (2.0% BW Bermuda hay) over a 22-week period. Results indicated that the highest final body weight (FBW) was significantly observed at the highest feeding level (T4), with females reaching 14.9 kg and males 20.9 kg, while the highest average daily gain (ADG) values were recorded for females in T3 at 75.7 g/d and males in T4 at 81.0 g/d (p<0.05). Dry matter intake (DMI) was highest in the T4 group for both females (437.4 g/d) and males (635.9 g/d), with significant differences observed across treatments (p<0.05), whereas the feed conversion ratio (FCR) showed an improving trend, particularly with a value of 6.0 for females in T4. For structural development, the highest feeding levels led to significant increases in body length, body depth, chest width, and chest girth of both sex. Female and male in T4 achieved body lengths of 53.5 cm and 61.8 cm, and body depths of 45.2 cm and 54.8 cm, respectively. Chest width and girth reached 15.9 cm and 66.5 cm in males, and 13.5 cm and 56.5 cm in females. In conclusion, higher feeding levels, especially with Bermuda hay, may positively influence the growth performance and structural development of goats.

The role of the gut microbiota in colorectal cancer (CRC) development has garnered attention, highlighting probiotics as potential adjuncts in CRC prevention and treatment. In recent years, probiotics and their derivatives have demonstrated mechanisms that may contribute to anticancer properties. This study investigates the cytotoxic effects of Bifidobacterium bifidum KCTC 3357, Lacticaseibacillus rhamnosus KCTC 5033, Limosilactobacillus reuteri VA 103, Bacillus galactosidilyticus VA 107, and Lactococcus taiwanensis VE101 on CT-26 mouse colon carcinoma cells using live cells, heat-killed cells (paraprobiotics), and cell-free supernatants (CFS, postbiotics) through an MTT assay. The results indicate that live bacterial strains, such as KCTC 3357, VA 103, and VA 107, promoted CT-26 cell viability, while heat-killed cells and CFS exhibited dose-dependent cytotoxicity. Inactivated forms of KCTC 3357 and VE 101, as well as CFS at 10 mg/mL concentration of KCTC 5033, VA 103, and VE 101, showed the strongest antiproliferative effects. These findings suggest that non-viable probiotic derivatives, such as paraprobiotics and postbiotics, offer promising therapeutic potential for CRC, providing a safer and more stable alternative to live probiotics. However, further research is required to explore their mechanisms of action, in vivo efficacy, and potential clinical applications.
