As product packaging becomes an increasingly important tool for conveying brand images to consumers, eco-friendly packaging (EFP) is being extensively adopted by fashion companies. Given this trend, the need for research examining consumer responses to fashion products featuring EFP has increased. This study investigates the effects of attitude and subjective norms on consumers’ purchase intention of fashion products using EFP, and further explores the moderating roles of gender and ethical self-identity (ESI). A survey including 360 male and female consumers in their 20s and 30s was conducted, and the data were analyzed using multiple regression analysis. The results indicate that both attitude and subjective norms positively influence purchase intention. Gender moderated the relationship between subjective norms and purchase intention, with males exhibiting higher purchase intention than females when influenced by social norms. ESI also moderated the relationship between attitude and purchase intention, as well as between subjective norms and purchase intention. Individuals exhibiting higher levels of ESI showed stronger alignment between their attitudes or perceived norms and their purchase intention of EFP products. These findings provide valuable insights and establish a foundational understanding of the key determinants of purchase intention for fashion products with EFP. Furthermore, they provide theoretical insights into sustainable consumer behavior and offer practical implications for fashion marketers seeking to promote eco-conscious consumption.

This study investigates the effects of experiential marketing by categorizing fashion pop-up store experiences according to the strategic experiential modules (SEMs): sensory, emotional, cognitive, behavioral, and relational. It analyzes how these experiential factors influence shopping flow, impulse buying, and word-of-mouth intentions. A survey was conducted with 400 participants, equally distributed by gender and age group (20 and 30-year-old). Valid responses from 320 participants were analyzed using factor analysis, reliability testing, correlation analysis, and regression analysis in SPSS. Findings revealed four key elements of experiential marketing: sensory/emotional, relational, cognitive, and behavioral. Sensory/emotional, relational, and cognitive factors positively affected shopping flow, which enhanced impulse buying and word-of-mouth intentions. However, behavioral factors did not have a significant effect. These results underscore the impact of experiential marketing on pop-up store customer behavior and highlight the understudied area of word-of-mouth marketing. The study specifically targeted consumers most likely to visit pop-up stores, ensuring practical significance by providing data to develop strategies for increasing experiential marketing efficiency. Additionally, the results identify the critical elements of experiential marketing in pop-up stores and examine how they interact with shopping flow and impulse buying. This research contributes valuable insights into optimizing consumer engagement in pop-up retail environments, emphasizing the importance of sensory and relational experiences in driving consumer behavior and addressing gaps in existing marketing literature.

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.

Background: With the increase of seated work, interest in forward head posture (FHP) has grown. Prolonged computer tasks with FHP have been considered a factor that increases the stiffness and tone of the upper trapezius (UT) muscle. Traditionally, many studies have measured the craniovertebral angle (CVA) in standing positions to assess FHP, making it difficult to determine whether the CVA measured in a habitual working posture correlates with the stiffness and tone of the UT muscle in office workers. Objects: This study aimed to investigate the relationship among CVA, UT muscle stiffness, and tone in both habitual working and standing postures among asymptomatic office workers. Methods: Forty asymptomatic office workers participated in the study. CVA was measured in both habitual working and standing postures. Stiffness and tone of the UT muscle were assessed after a 10-minute computer task. Pearson’s correlation coefficient was used to investigate the relationship between CVA and stiffness and tone of the UT muscle. Results: No significant correlations were found between CVA in standing posture and the stiffness and tone of the UT muscle. However, moderate negative correlations were observed between CVA measured in the habitual working posture and both the stiffness (dominant: r = –0.490, non-dominant r = –0.465) and tone (dominant: r = –0.501, non-dominant r = –0.446) of the UT muscle. Conclusion: This study highlights that decreased CVA in habitual working posture is associated with increased stiffness and tone of the UT muscle in asymptomatic office workers. Therefore, measuring CVA in the habitual working posture should be considered when evaluating stiffness and tone of the UT muscle.

Though Farnesiferol C (FC) derived from Ferula asafoetida is known to have antiangiogenic and apoptotic effect in gastric, breast, nonsmall lung cancers, the underlying antitumor mechanism of FC is not fully understood so far. Hence, in the current study, apoptotic mechanism of FC was explored in colon cancers in association with carbon catabolite repression 4-negative on TATA-less 2 (CNOT2)/c-Myc signaling. Herein FC significantly increased cytotoxicity and reduced the number of colonies in HCT116 cells more effectively than in SW480 cells, though FC enhanced sub-G1 cell population in HCT116 and SW480 cells compared to untreated control. Consistently, FC activated the cleavages of Poly ADP-ribose polymerase (PARP) and Bax and attenuated the expression of pro-PARP and Cyclin D1 in HCT116 cells better than SW480 cells. Also, FC significantly reduced the expression of CNOT2 and c-Myc. Also, FC reduced of c-Myc stability in HCT116 cells by cycloheximide assay. Notably, CNOT2 depletion reduced the expression of c-Myc, while c-Myc depletion also attenuated the expression of CNOT2 in HCT116 cells, implying the crosstalk between CNOT2 and c-Myc. Furthermore, overexpression of c-Myc or CNOT2 promoted the expression of pro-PARP in HCT116 cells. Overall, these findings suggest that FC induces apoptosis via inhibition of CNOT2 and c-Myc in colon cancers for a potent anticancer candidate for further agriculture cultivation in Korea.

Background: Ankle flexibility is important for maintaining proper biomechanical function. Static stretching is used to improve flexibility with minimal risk; however, its effects are often temporary. Transfer of energy capacitive and resistive (TECAR) therapy has the potential to enhance muscle flexibility and circulation through deep heat applications. However, comparative studies evaluating the effectiveness of TECAR therapy and static stretching are lacking. Objects: This study aimed to compare the effects of static stretching therapy (ST) and combined TECAR and static stretching therapy (T-ST) in subjects with gastrocnemius muscle (GCM) tightness. Methods: Twenty-seven participants with bilateral GCM tightness were enrolled. To administer the ST and T-ST, which were each applied to both legs, the participants stood for 15 minutes on a wedge with a 0°–15° incline, with both feet on the wedge during ST and with TECAR therapy in resistive energy transfer mode applied to only one side of the GCM during T-ST. Muscle stiffness (MyotonPRO), dorsiflexion range of motion (DF-ROM), peak torque, and pennation angle (PA) of the GCM were measured before and after the intervention. Normality was confirmed using the Shapiro–Wilk test. Differences between the ST and T-ST leg conditions and between pre- and post-intervention changes in the legs were analyzed using paired t-tests. Results: There were no significant differences in any of the measured variables between the legs before the intervention. ST and T-ST legs showed significant improvements in all measured variables after the intervention (p < 0.05). T-ST legs demonstrated a significantly greater increase in DF and a greater decrease in PA than ST legs (p < 0.05). Conclusion: T-ST outperformed ST in reducing PA and increasing DF-ROM by promoting deep tissue relaxation and stimulating metabolic activity. This may lead to reduced pain and greater flexibility compared to ST. Maintaining an optimal PA ensures efficient force transmission during exercise, as evidenced by the observed increase in peak torque.

Background: Portable, small computers and smartphones are now considered essential tools in modern society and smartphone ownership and usage rates are rising every year. However, excessive smartphone use can have musculoskeletal and postural implications, leading to “smartphone addiction” and related dysfunctions. Objects: This study aimed to investigate the effects of smartphone addiction on scapular position and muscle activity during shoulder abduction in asymptomatic individuals. Methods: A total of 45 participants were classified into high-risk, middle-risk, and low-risk groups based on their smartphone addiction levels. Scapular position was measured using the scapular index, round shoulder posture (RSP), lateral scapular slide test, and scapulohumeral rhythm spine angle. Muscle activity was assessed using electromyography of the upper trapezius (UT), lower trapezius (LT), serratus anterior (SA), and anterior deltoid (AD) muscles during shoulder abduction. Results: Smartphone addiction was significantly associated with altered scapular position and muscle activity. The high-risk group exhibited greater forward head posture and more pronounced RSP. Additionally, the high-risk group had lower SA activation and higher UT, LT, and AD muscle activity, indicating compensatory mechanisms due to altered scapular positioning. Conclusion: These findings suggest that excessive smartphone use contributes to postural deviations and altered muscle activation patterns, which may lead to musculoskeletal dysfunction over time. Clinicians should consider smartphone use when assessing patients with scapular dysfunction, and future studies should explore interventions to mitigate these effects.

Background: Logistics service workers (LSWs) face significant occupational challenges, with ankle sprains being the second most prevalent work-related musculoskeletal disorder. Foot posture, assessed through the navicular drop test, can significantly influence dynamic balance performance, which is crucial for injury prevention in physically demanding occupational settings. Objects: This study aimed to investigate differences in dynamic balance performance among LSWs with pronated, supinated, and normal foot types using the Y-Balance test (YBT), comparing reach distances across anterior, posteromedial, and posterolateral directions. Methods: A total of 205 LSWs were classified into three groups based on navicular drop measurements: supinated (n = 44), normal (n = 94), and pronated (n = 67) foot types. The YBT was performed on the dominant leg, measuring reach distances in three directions. Participants’ demographic characteristics were recorded, and statistical analyses were conducted using one-way analysis of variance (ANOVA) with Bonferroni correction. Results: Significant differences in YBT performance were observed across all three directions (anterior: p = 0.009, posterolateral: p = 0.015, posteromedial: p = 0.014). The supinated and normal foot groups showed significantly greater reach distances compared to the pronated group (p < 0.026 for anterior direction). In the posterolateral direction, the supinated group demonstrated significantly better performance compared to the pronated group (p = 0.014). Similarly, the posteromedial direction revealed significantly higher reach distances for the supinated group compared to the pronated group (p = 0.012). Conclusion: The study reveals that foot type significantly impacts dynamic balance performance among LSWs. Workers with pronated feet demonstrate reduced balance capabilities, while those with supinated feet show the most superior dynamic balance performance.

Background: Chronic low back pain (CLBP) is associated with trunk and lower extremity muscle weakness. Kneeling squat (KS) is a hip-focused exercise commonly used in the activities of daily living. However, research on trunk and lower extremity muscle activity across movement phases (ascending, holding, and descending) during KS remains limited and warrants further investigation. Objects: To determine the muscle activity of transversus abdominis/internal oblique (TrA/IO), erector spinae, gluteus maximus (Gmax), gluteus medius (Gmed), rectus femoris (RF) in the contraction phases of KS in individuals with CLBP. Methods: Surface electromyography data were recorded during KS across the ascending, holding, and descending phases on the side with CLBP. A 60-bit metronome was used to control the exercise speed. Results: The muscle activity of the TrA/IO was significantly higher during the holding phase than during the ascending and descending phases. The Gmax and Gmed were significantly higher during the holding phase than during the descending phase, whereas, RF was significantly higher during the ascending phase than during the holding and descending phases. Conclusion: The holding phase of KS may be recommended as a trunk and lower extremity exercise to increase in TrA/IO, Gmax, and Gmed muscle activity. Additionally, the ascending phase activates RF muscle in individuals with CLBP.

Background: Hamstring shortness (HS) contributes to the limit of hip and knee range of motion and can limit the execution of multi-segmental movement exercises such as squatting, thereby altering the muscle activation. The double leg squat (DS) is fundamental exercise for knee injury rehabilitation programs. However, it may aggravate knee joint injury and cause low back pain. The Bulgarian split squat (BSS) is a one-leg squat exercise with greater knee joint stability than DS. Measuring muscle activation during the squat will provide insight into the contribution of hamstring activation and quadriceps and hamstring (Q:H) ratio to the knee in participants with HS. Objects: This study compares hamstring activation and Q:H ratios during squat exercises in individuals with and without HS. Methods: This study classified 30 healthy participants, based on active knee extension, into two groups: with HS and without HS. Surface electromyography was performed to determine muscle activation of the medial hamstring (MH) and biceps femoris of the hamstrings and coactivation of the Q:H. All participants performed DS and BSS. Results: MH activity was significantly higher in the with HS group than in the without HS group during all exercises, and the Q:H ratio was significantly closer to 1.0 during BBS compared to DS. Additionally, the with HS group had a significantly lower Q:H ratio than without HS group. Conclusion: In comparison between exercises, BBS can bring the Q:H ratio closer to 1.0 compared to DS, which may enhance knee stability. However, in between-group comparisons, the increased tension due to the shortening of the hamstrings leads to heightened hamstring activation, resulting in a Q:H ratio that is closer to 1.0 compared to the without HS group. Therefore, relying solely on the Q:H ratio to assess knee stability may be risky.

Background: Aquatic exercise utilizing hot springs helps individuals with nonspecific knee pain by reducing joint stress and providing a safe environment for movement. It can improve muscle strength and balance, enhancing overall functional mobility. Objects: This study aims to examine the muscle strength of knee flexion, knee extension, dorsiflexion, and plantar flexion, as well as to investigate static and dynamic balance in middleaged females after performing hot spring aquatic exercise for 4 weeks. Methods: Twenty-two middle-aged females participated in the study. The participants performed hot spring aquatic exercise for 4 weeks. The hot spring aquatic exercise consisted of aquatic walking, aquatic stretching, aquatic side step, aquatic forward reach, aquatic squat, leg lift, and aquatic arm and leg rotation. Muscle strength was measured using microFET2, while static balance was assessed through the one-leg stance test, and dynamic balance was evaluated using the Y-balance test. This study utilized the paired t-test for statistical analysis, with a significance level set at 0.05. Results: The muscle strength of bilateral knee flexion showed a significant increase in the pre- and post-comparison (p < 0.05), and the muscle strength of bilateral knee extension also improved significantly (p < 0.05). In addition, a significant increase was observed in the muscle strength of bilateral dorsiflexion (p < 0.05). The one-leg stance test performed while supporting on the right leg showed a significant increase in the pre- and post-comparison (p < 0.05). Furthermore, the dynamic balance measurements performed while supporting on both the right and left legs demonstrated significant improvements in both legs when compared before and after the intervention (p < 0.05). Conclusion: In individuals with nonspecific knee pain, a 4-week hot spring aquatic exercise program can contribute to the improvement of lower extremity strength, as well as static and dynamic balance ability.

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.
