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.

Sea buckthorn (Hippophae rhamnoides L.) is a thorny, nitrogen-fixing shrub native to Europe and Asia. Known as the “vitamin tree,” sea buckthorn is an important fruit resource for the Mongolian people. However, comparative studies on the antioxidant activity of wild sea buckthorn in Mongolia are still lacking. Therefore, the objective of this research was to determine the optimal extraction method to maximize its functional properties and to evaluate the antioxidant and antimicrobial activities of wild Mongolian sea buckthorn berry extracts. The wild Mongolian berries were extracted using hot water, 70% methanol, and 70% ethanol through three different extraction methods: homogenizer-assisted extraction, ultrasonication-assisted extraction, and Soxhlet extraction. The antioxidant and antimicrobial activities of the sea buckthorn extracts were assessed by measuring total phenolic content (TPC), total flavonoid content (TFC), DPPH free radical scavenging activity, ferric reducing antioxidant power (FRAP), reducing power, nitric oxide (NO) radical scavenging capacity, nitrite scavenging activity, and the diameters of inhibition zones against foodborne pathogens. The DPPH free radical scavenging capacity and FRAP of the sea buckthorn berries extracted using Soxhlet with 70% ethanol were 57.36% and 1.035 mg FSE/g, respectively. The Soxhlet 70% ethanol extract also exhibited the highest reducing power (1.961), NO radical scavenging ability (64.7%), and nitrite scavenging ability (62.4%) among the tested samples. The hot water, 70% methanol, and 70% ethanol extracts exhibited concentration-dependent antimicrobial activity. The homogenizer-assisted 70% ethanol extract formed a clear inhibition zone of 13 mm against Salmonella enteritidis.

본 논문은 인도 영어극에서 가장 중요한 목소리 중 하나인 아시프 쿠림 보이의 선택된 희곡들에 나타난 식민주의의 주제와 재현 방식을 고찰한다. 쿠림보이의 희곡들은 식민주의의 개념과 그 다양한 양상을 드러내며, 자본주의가 독립 이후 인도 사회 전반에 미친 영향을 바탕으로 식민주의의 비인간화 행위를 지적한다. 그의 희곡들은 학문적 연구의 대상으로 다루어졌으며, 일부는 지역어로 번역되기도 하였다. 쿠 림보이의 작품은 역사와 정치 등 폭넓은 주제를 포괄하고 있으며, 인종, 계급, 젠더와 같은 문제들이 많은 작품에서 부각되지만 이에 대한 심층적인 논의는 아직 부족하다. 그는 시대의 중대한 문제들에 대한 지속적인 관심을 통해 삶에 대한 독자적인 시각을 형성하며, 동시대적 주제에 대한 뚜렷한 입장을 가진 독특한 극작가로 평가된다. 또한 그는 현대 사회의 비참한 현실을 가감 없이 드러내는 데 주력한다.

인도 연극의 선구자인 비제이 텐둘카르는 인도 연극을 전통적 뿌리에서 현대적이고 혼종적인 형태로 탈바꿈시키는 데 중추적인 역할을 하였다. 본 논문은 텐 둘카르의 작품이 어떻게 토착 문화 요소와 서구 모더니즘의 영향을 결합하며 인도 연 극의 진화를 반영하는지를 탐구한다. 산스크리트 희곡과 마하바라타, 라마야나와 같은 서사에 뿌리를 둔 전통 인도 연극은 도덕적 이분법과 사회 규범에 중점을 두었다. 그 러나 탈식민 시대의 인도 영어 연극, 특히 텐둘카르의 작품은 도시 중산층이 직면한 현대 사회 정치적 문제들을 다루는 방향으로 전환되었다. 텐둘카르의 􋺷정숙! 재판이 진행 중이다􋺸는 가부장제, 성 역할, 사회적 위선과 같은 주제를 조명하며 그 전환을 대표하는 사례 연구로 제시된다. 이 희곡은 모의 재판이라는 개념을 통해 사회적 불의 와 여성 억압을 비판하며, 현대 인도 사회의 보다 넓은 투쟁을 상징한다. 텐둘카르의 인도주의적 접근은 기존의 규범에 도전하며 진정성, 성실성, 새로운 도덕 질서를 옹호 한다. 그의 심리적, 실존적, 여성주의적 문제에 대한 집중은 현대 삶의 분열성을 부각 시킨다. 본 논문은 텐둘카르만의 독특한 시각을 분석함으로써, 인도 연극이 사회 비판 과 문화적 혼종성의 장으로 진화한 과정을 보여준다.

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.

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 a common health problem among female caregivers. In Korea, 70.4% of caregivers experience LBP after caregiving. The prevalence of LBP was higher in female caregivers of patients who required physical assistance with transfer than in those caring for patients who did not require physical assistance. Lifting movements, such as patient transfer and positioning, are associated with lumbopelvic stability (LPS) and knee muscle strength. However, no studies have investigated the differences in LPS and knee muscle strength between female caregivers with and without CLBP. Objects: This study was conducted to investigate the differences of the LPS, knee extension strength (KES) and knee flexion strength (KFS) between female caregivers with and without CLBP. Methods: Thirty-one female caregivers participated in this study. Participants were divided into two groups: (1) caregivers without CLBP (n = 13) and (2) caregivers with CLBP (n = 18). LPS, KES, and KFS levels were measured. An independent t-test was used to compare the LPS, KES, and KFS between caregivers with and without CLBP. The statistical significance was set at α of 0.05. Results: The LPS and KES scores were significantly lower in caregivers with CLBP than those without. In contrast, the KFS did not differ significantly between the groups. Conclusion: This study observed associations of both LPS and KES with CLBP among female caregivers.

This longitudinal study used data from the Busan Educational Longitudinal Study (BELS) to identify growth profiles of English class self-efficacy (ECS) over three years and their associations with English class comprehension, engagement, and achievement. A middle school student sample from 2016 to 2018 BELS comprised 3,038 students (1,394 females and 1,644 males) from 56 middle schools in South Korea. Using a personcentered approach with Mplus 8.4, a higher-order growth mixture modeling (GMM) yielded three distinct growth trajectories of ECS: 82.8% of initially high and slowly decreasing (HSD) group, 9.7% of intermediate high and decreasing (IHD) group, and 7.5% of low but increasing (LI) group growth profiles. Results indicated that English class comprehension, engagement, and achievement showed statistically significant mean differences across each growth profile of ECS. The identified ECS growth profiles can be used to tailor intervention measures. Empirical findings are discussed in terms of pedagogical implications in applied language learning and teaching practices and further research.

Uranium-contaminated soil can be effectively decontaminated through acid leaching; however, this process process generates significant amounts of radioactive wastewater. Therefore, developing efficient methods to remove uranium from wastewater is essential to minimize radioactive waste generation. This study investigates the applicability of various precipitation methods for uranium removal from acidic wastewater produced during soil-washing processes. Three methods were evaluated: metal hydroxide (M–OHx) co-precipitation, uranium peroxide (UO4) precipitation, and uranium phosphate (KUO2PO4) precipitation. The M–OHx precipitation method removes uranium by precipitating excess metal ions in wastewater by adjusting the pH. This method is easy to use and has a high removal efficiency. The UO4 and KUO2PO4 precipitation methods involve adding reagents to precipitate uranium in the mineral phase. They enable selective uranium separation and further volume reduction. In the results, M–OHx and KUO2PO4 precipitation methods remove uranium to less than 1 mg∙L−1 within 2 h, demonstrating superior capabilities compared to UO4 precipitation. The optimal method is different depended on the management strategy for the recovered uranium. The M–OHx precipitation method was suitable for permanent disposal, whereas KUO2PO4 could be recycled. Based on these findings, guidelines for the effective treatment of wastewater containing uranium from the soil-washing process can be established.

Writing conferences are one-on-one feedback sessions that enable teachers and students to engage in constructive interactions to improve students’ writing. While interacting individually, a teacher can use various feedback strategies to improve the quality of a student’s writing. This study examined how a secondary English teacher elicited students’ self-correction of writing issues during EFL writing conferences conducted in Korean (L1) as part of an after-school English program at a Korean high school. One English teacher and five first-year students participated in writing classes for two weeks during the winter vacation. Their conversations were video-recorded and analyzed using Conversation Analysis. Findings revealed that the teacher elicited the student’s selfcorrection through four key strategies: (1) metalinguistic clues, (2) building on initial corrections, (3) leveraging morphological knowledge, and (4) guiding students through a stepwise construction of sentence elements. This study can enhance our understanding of corrective feedback in secondary EFL writing conferences and offer insights for improving teacher-student feedback interactions.

Sodium sulfate, as a commonly used early strengthening agent, has been widely used in different areas. Because of its sulfonic acid group, sodium sulfate is also used as a cement capillary crystal waterproof material. However, temperature has a significant effect on concrete mixed with sodium sulfate. The effect of sodium sulfate on the early hydration rate at different temperatures was studied by conducting a time and hydration thermal analysis. The effects of sodium sulfate on the mechanical properties of concrete at different temperatures were studied through compressive strength experiments. Impermeability at different temperatures was studied by testing resistance to chloride ion penetration and resistance to water penetration. The effect of resistance to sulfate attack was also experimentally. The hydration products were analyzed by electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The experimental results showed that at low temperature, sodium sulfate can accelerate the early hydration reaction rate, and the effect becomes weaker with increasing temperature. At low temperature, the addition of sodium sulfate can effectively improve the degree of hydration, and enhance the permeability resistance and ion erosion resistance of the matrix.

During an investigation of indigenous prokaryotic species in the Republic of Korea, 17 bacterial strains belonging to the phylum Bacteroidota and 4 strains belonging to the phylum Bacillota were isolated from freshwater environments. These isolated bacterial strains formed a robust phylogenetic clade with type strains of the closest related bacterial species, with 16S rRNA gene sequences sharing similarities of higher than 98.7%. To date, there have been no official report of these 21 isolates in the Republic of Korea. At the genus level, these unreported species were affiliated with Mucilaginibacter and Pedobacter of class Sphingobacteriia, Flavobacterium and Gillisia of class Flavobacteriia, Hymenobacter of class Cytophagia, and Paenibacillus and Planococcus of class Bacilli. These species were further examined by performing Gram staining, analyzing their colonies and cell morphologies, and determining their basic biochemical characteristics and phylogenetic positions. Detailed descriptions of the 21 previously unreported species are provided.

Uranium-contaminated soil can be cleaned using an acid washing process. However, high-concentration acid washing generates substantial amounts of radioactive waste, making it essential to develop a treatment process using low-concentration acid. This study evaluated the effectiveness of low-concentration sulfuric acid washing for uranium removal from contaminated soil. Experiments were conducted with a 0.05 M sulfuric acid solution. With a mixing ratio of soil to acid solution at 1:5, three consecutive washes were sufficient to remove uranium from contaminated soil to clearance level. During the acid washing process, real-time pH monitoring was performed to analyze the correlation between uranium leaching and pH changes. This led to the establishment of a monitoring-based process control strategy. In conclusion, we identified an effective method for removing uranium from soil under low acid concentration conditions. Consequently, significant reductions in radioactive waste generation are anticipated.

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.

Freshwater environments serve as crucial habitats for diverse microorganisms, playing essential roles alongside plants and animals within the ecosystem. Bacteria in these environments are particularly important for maintaining ecosystem functions. Among them, members of the phylum Pseudomonadota are known to be involved in processes such as nitrogen fixation, ammonia oxidation, and biofilm formation. Pseudomonadota comprises six classes: Acidithiobacillia, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Hydrogenophilia, and Zetaproteobacteria. This study reports 43 previously unrecorded species belonging to the phylum Pseudomonadota. They were isolated from various freshwater habitats in Republic of Korea. These strains were isolated and cultured using nine different standard media, with classification based on Gram staining, cell morphology, and biochemical characteristics. Species identity was determined using 16S rRNA gene sequencing, with a similarity threshold of 98.7% for designation as unreported species. Phylogenetic analysis revealed that these 43 strains were distributed across three classes, 13 orders, 28 families, and 39 genera. This research emphasizes microbial diversity in freshwater ecosystems and provides valuable insights into ecological roles and potential novel functions of unreported bacterial species in Korea.

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.
