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 aimed to analyze the characteristics of the New-Chinese style appearing in Chinese fashion designer Shiatzy Chen’s collections and, accordingly, recommend various directions for the New-Chinese style design. Regarding the research method, the background and concept of Chinese style and New-Chinese style were reviewed, while relevant characteristics were derived from prior research. Concerning the data collection, 21 season collections from A/W 2014 to A/W 2024, were selected, and 26 reviews and 1,168 collection data were collated. The results are as follows: First, “multicultural convergence” emerges as design methods reflecting social changes and utilizes diverse cultural elements. In fashion design, it emerges in a harmonious combination of culture and artistic styles, expressing the integration of varied cultures —for instance, East–West cultural convergence. Second, “historical tradition” consistently expresses Shiatzy Chen’s fashion; continuously explores Chinese people’s garments and aesthetics; and integrates oriental dignity, culture, and discipline into fashion design. Third, “temporary diversity” refers to a Chinese fashion design culture that represents the seamless blending of traditional culture and modern social values— leading the new consumer market by combining new and old generations, graffiti aesthetics on modern streets, and traditional and contemporary expressions. Fourth, “positive metaphor” expresses the intrinsic mental element and emphasizes covert rather than overt beauty. These expressions metaphorically communicate ancient Chinese legends via artistic techniques, such as contemporary illustration and embroidery, thereby conveying an active mental culture.
본 연구는 담액수경재배(Deep Flow Technique, DFT)로 재배된 잎들깨(Perilla frutescens)의 생장 및 생리 적 반응에 미치는 인산결핍의 영향을 분석하였다. 인산 결핍 처리는 야마자키 표준 배양액을 수정하여 0% (대조 구), 30%, 50%, 70%, 100%의 5 수준으로 달리 조성하였다. 처리 20일부터 80일까지 인산 결핍 수준이 증가함에 따라 초장, 엽수, 마디 수, 경직경이 유의미하게 감소하였다. 80일째에는 100% 인산 결핍 처리에서 초장이 10.1cm, 엽수는 식물체당 2.7장으로 급감하였으며, 이는 대조구의 73.5cm 및 12.8장에 비해 현저한 생장 저해를 나타냈다. 또한, 인산 결핍 조건에서 생체중과 건물중 모두 현저히 감소하였으며, 대조구의 생체중은 93.4g 이었으나 100% 인산결핍 처리구에서는 2.1g으로, 건물중은 11.8g에서 0.4g으로 크게 감소하였다. 인산 결핍 정도가 증가할수록 하 부엽에서 황화(Chlorosis) 및 괴사(Necrosis)와 같은 생리장해 증상이 뚜렷하게 나타났다. 이러한 결과는 인산이 잎 들깨의 영양생장과 건물생산량 증가에 필수적인 역할을 수행함을 나타내었다.
This study aimed to evaluate the anti-inflammatory, whitening, and anti-wrinkle effects of nicotinamide mononucleotide (NMN) and NMN-containing serum. To investigate the anti-inflammatory effects of NMN, a lipopolysaccharide (LPS)-induced RAW264.7 macrophage model was used. The results demonstrated that NMN exhibited no cytotoxicity at concentration up to 1%. Additionally, 1% NMN significantly inhibited nitric oxide (NO) production induced by LPS and suppressed the protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), both of which are key inflammatory enzymes. Furthermore, to assess the whitening and anti-wrinkle effects of NMN, tyrosinase inhibition, elastase inhibition, and collagenase inhibition assays were conducted. The results showed that 1% NMN inhibited tyrosinase activity by 10.85%, elastase activity by 18.69%, and collagenase activity by 91.94%. These research results suggest that although NMN has a relatively limited whitening effect, it has significant potential as an anti-inflammatory and wrinkle-improving agent, suggesting its potential as a cosmetic material.

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.

The purpose of this study is to provide the basic data necessary for establishing a system for analyzing the dimensions and body types of men aged 30–59. The subjects were 1,247 adult males selected based on data from the 8th Korean anthropometric survey; the direct and calculated values constituted 36 items; and descriptive statistics analysis, factor analysis, and cluster analysis were conducted. the descriptive statistics analysis revealed that the weight difference between individuals was high, while the height difference was low. Overall, the differences between individuals were high in waist-related items and low in lower limb circumference-related items. It was found that knee height and hip side length increased in subjects aged in their late 30s and decreased in those aged in their early 50s, while lower leg circumference decreased with age from the late 30s onward. The factor analysis identified four dimensions: “horizontal size of lower body,” “vertical size of lower body,” “hip length,” and “ankle size.” on the basis of the cluster analysis, they were classified into the following types: “tall body shape with long waist and hips, bent legs and hips, thick legs and ankles,” “slim body shape with short legs and short hips,” and “slim body shape with short legs and thin ankles.” A follow-up study is required to analyze changes in body shape over time based on annual measurements. We believe that this study will furnish basic data for establishing a measurement system for men’s clothing.

In recent years, high-entropy alloys (HEAs) have attracted considerable attention in materials engineering due to their unique phase stability and mechanical properties compared to conventional alloys. Since the inception of HEAs, CoCrFeMnNi alloys have been widely investigated due to their outstanding strength and fracture toughness at cryogenic temperatures. However, their lower yield strength at room temperature limits their structural applications. The mechanical properties of HEAs are greatly influenced by their processing methods and microstructural features. Unlike traditional melting techniques, powder metallurgy (PM) provides a unique opportunity to produce HEAs with nanocrystalline structures and uniform compositions. The current review explores recent advances in optimizing the microstructural characteristics in CoCrFeMnNi HEAs by using PM techniques to improve mechanical performance. The most promising strategies include grain refinement, dispersion strengthening, and the development of heterogeneous microstructures (e.g., harmonic, bimodal, and multi-metal lamellar structures). Thermomechanical treatments along with additive manufacturing techniques are also summarized. Additionally, the review addresses current challenges and suggests future research directions for designing advanced HEAs through PM techniques.
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.
As social media becomes increasingly integrated into daily life, it has reshaped how people communicate and consume advertising. Instagram, a visually-oriented platform, uses advanced targeting and shopping features to deliver personalized advertising, particularly in the fashion retail sector. Grounded in the cognitive-affective-behavioral model and human information processing theory, this study investigates how Instagram’s personalized fashion advertising influences consumer perception and behavior, focusing on recommendation system quality (accuracy, novelty, diversity) and content quality (vividness, diagnosticity). A survey of 403 Korean adults aged 20–69 was conducted to assess causal relationships among these variables. The findings reveal that accuracy and diversity in recommendation systems, along with diagnosticity of content quality, positively influence user satisfaction, which, in turn, influences their click-through and purchase intentions. However, novelty and vividness exhibited no significant effects. Academically, the study contributes to a deeper understanding of the mechanisms underlying personalized advertising on visuallyoriented platforms like Instagram. Practically, it underscores the importance of creating high-quality, personalized content that aligns with user preferences and provides clear product information. Brands can enhance user engagement by designing visually appealing advertisements and optimizing linked web pages to foster emotional bonds with consumers. These strategies can cultivate long-term customer relationships and enhance brand loyalty while maximizing advertising effectiveness on Instagram.
This study investigated the ultra-low-temperature (4.2 K) tensile properties and deformation mechanisms of stainless steel 304L manufactured via laser powder bed fusion (LPBF). The tensile properties of LPBF 304L were compared to those of conventional 304L to assess its suitability for cryogenic applications. The results revealed that LPBF 304L exhibited a significantly higher yield strength but lower ultimate tensile strength and elongation than conventional 304L at 4.2 K. The temperature dependence of the yield strength also favored LPBF 304L. Microstructural analysis demonstrated that LPBF 304L features a high density of dislocation cells and nano-inclusions, contributing to its greater strength. Furthermore, strain-induced martensitic transformation was observed as a key deformation mechanism at cryogenic temperatures, where austenite transformed into both hexagonal-closed packed (HCP) and body-centered cubic (BCC) martensite. Notably, BCC martensite nucleation occurred within a single HCP band. These findings provide critical insights into the mechanical behavior of LPBF 304L at cryogenic temperatures and its potential for applications in extreme environments.

Metal additive manufacturing (AM) facilitates the production of complex geometries with enhanced functionality. Among various AM techniques, laser powder bed fusion (LPBF) is distinguished by its precision and exceptional mechanical properties achieved via laser fusion deposition. Recent advancements in AM have focused on combining LPBF with post-processing methods such as cold rolling, high-pressure torsion, and forming processes. Therefore, understanding the forming behavior of LPBF-processed materials is essential for industrial adoption. This study investigates the stretch-flangeability of LPBF-fabricated 316L stainless steel, emphasizing its anisotropic microstructure and mechanical properties. Hole expansion tests were employed to assess stretch-flangeability in comparison to wrought 316L stainless steel. The results demonstrate that LPBF-processed samples exhibit significant anisotropic behavior, demonstrating the influence of microstructural evolution on formability. These findings contribute valuable insights into optimizing LPBF materials for industrial forming applications.
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.
This study investigated the impact of various soil environmental factors on the growth and yield of Actinidia arguta (A. arguta) in Suwon, South Korea. By employing Pearson correlation analysis, we explored the relationships between soil properties such as pH, electrical conductivity (EC), organic matter content, available phosphorus, available silicon, soil moisture, and soil temperature with A. arguta growth and yield. The results revealed that soil temperature and EC had the strongest positive correlations with A. arguta growth, while organic matter content exhibited a strong negative correlation with fruit yield. The high levels of available phosphorus emerged as a potential adverse factor affecting yield. These findings suggest that managing soil temperature, EC, and phosphorus levels is crucial for optimizing A. arguta productivity. Future research should focus on fine-tuning phosphorus levels and further investigating the interactions between soil factors to enhance A. arguta yield and sustainability.
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.
