This study explores how to integrate the generative artificial intelligence (AI) tool Midjourney into the fashion design process, emphasizing the visualization of sporty fashion concepts. The research applied Midjourney at every stage of the fashion design process: mood board, fashion sketch, flat drawing, production package, fashion show presentation, and store display and sales. Specifically, sporty fashion was selected as the theme, and customized prompts were developed from prior research and design principles to generate visual outputs for each stage. Furthermore, three apparel design experts evaluated the AI-generated images to assess Midjourney’s practical applicability and effectiveness in each phase of the fashion design workflow. Expert evaluations revealed that Midjourney was particularly effective in the early stages, offering diverse and visually engaging imagery that supported creative ideation and mood expression. The tool allowed quick exploration of different silhouettes during the sketching stage but was imprecise in detailed forms and proportions. Limitations became more evident in the flat drawing and work instruction stages, where outputs failed to accurately reflect material textures and technical construction. Prompt refinements and referencebased prompts were tested but often resulted in inconsistent or stylized outputs. Additionally, continuity between stages was missing. Midjourney shows potential as a creative tool, but experts highlight its limitations for practical industry application. Further research is needed to improve prompt optimization and training data for enhanced accuracy and usability in AI-assisted fashion design workflows.

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.

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.

본 연구는 ‘설향’ 딸기 유묘를 대상으로, 꽃눈 분화 유도 조건(단일일장, 야간 15°C)과 비유도 조건(연속광, 24－25°C)에서의 형태적 및 생리적 반응을 비교하여, 꽃눈 분화와 관련된 주요 생장 지표를 확인하고자 수행되었 다. 유묘는 15일간 각각의 환경 조건에 따라 처리된 후, 모든 처리구를 동일한 비유도 조건(연속광, 24－25°C) 하에 배양하며 총 49일간 관찰하였다. 관부 직경, 잎 수, 엽면적, 런너 수 등 형태적 지표와 함께 건물중 분포, 엽록소 농도 (SPAD), 가용성 당(자당, 포도당, 과당) 함량을 조사하였다. 그 결과, 꽃눈 분화 유도 처리군은 관부 직경과 뿌리 생 체량, 잎의 엽록소 농도가 유의하게 높았으며, 이는 생식 생장으로의 전환을 나타내는 초기 지표로 판단되었다. 반 면, 비유도 조건에서는 잎 수, 런너 수, 줄기 생체중, 엽면적이 증가하여 영양생장이 지속됨을 확인하였다. 특히, 유 도 처리 28일 이후 관부 내 자당 농도가 두드러지게 증가하였으며, 이는 꽃눈 분화 개시와의 관련성을 시사한다. 본 연구는 환경 조건에 따른 딸기 유묘의 생장 반응 차이를 규명하고, 꽃눈 분화 예측과 정식 시기 결정을 위한 유용한 생리적 지표를 제시함으로써, 환경 제어 기반의 효과적인 유묘 관리 전략 수립에 기초자료를 제공할 수 있을 것으로 기대된다.

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.

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.

Road infrastructure development and biodiversity conservation are essential for sustainable development. However, many developing countries struggle to balance them. This study examines the impact of road construction in 24 African countries and evaluates strategies for achieving sustainability. Using a case study approach, road construction variables from individual country reports (2024) were quantitatively analyzed alongside Red List Index (RLI) scores from the Yale University's 2024 Environmental Performance Index Report. Descriptive statistics and regression analyses were applied to assess the relationship between road development and biodiversity conservation to provide insights into effective mitigation strategies. Results indicate that in 2024, the average RLI score for the 24 African countries was 64.74, with a 10-year mean decline of -2.85. On average, 17,162.21 ha of biodiversity habitats were cleared for road construction, emphasizing the vulnerability of biodiversity. Burkina Faso (95.4), Mali (92.9), and Botswana (92.2) exhibited strong biodiversity health, whereas Kenya (24.9), South Africa (24.4), Uganda (15.7), and Tanzania (0) faced critical challenges. Wildlife crossing was the most significant predictor in lower-income economies (R² = 0.49, p < 0.0001), traffic volume in lower-middle income economies (R² = 0.35, p = 0.0007), and road width in upper-middle income economies (R² = 0.83, p = 0.0054). Habitat clearance exhibited a weak correlation. These findings highlight the crucial role of road construction variables—particularly wildlife crossings, road width, and traffic volume—in biodiversity conservation across income groups. Targeted road planning is required to mitigate biodiversity loss. These findings contribute to the emerging literature on the impact of infrastructure on conservation, policy guidance, and mitigation efforts in developing countries.

이 논문은 W. B. 예이츠가 민주주의적 시인이었던 월트 휘트먼에게서 영향을 받아 출발했음에도 불구하고, 후기에는 권위주의에 이끌리는 복잡한 사상적 변 화를 겪었음을 고찰한다. 예이츠는 초기에 휘트먼이 제시한 ‘민중과 함께하는 시인의 이상’을 받아들였지만, 시간이 흐르며 대중 민주주의에 환멸을 느끼고 혼란과 문화적 수준 저하를 초래한다고 판단했다. 그는 엘리트주의적인 미학과 신비주의적 역사관을 통해 점차 권위와 질서를 옹호하는 방향으로 나아갔다. 이 연구는 아일랜드 독립 등 당시 역사적 상황과 함께 두 시인의 주요 작품을 면밀히 분석하고, 민주주의와 권위주 의 사이에서 갈등하는 현대 시인의 역할과 그 미학적 긴장을 조명하고자 한다.

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.

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.

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.

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.

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.

The utilization of pig slurry (PS) as an organic fertilizer plays a pivotal role in nutrient recycling within agricultural systems. However, this practice concomitantly leads nitrogen (N) losses through ammonia (NH₃) volatilization and nitrous oxide (N₂O) emissions. The objective of this study was to investigate the effect of wood biochar on mitigating NH3 and N2O emissions and enhancing N retention from PS-applied soil, and plant biomass production during the vegetative growth of rapeseed (Brassica napus L.). The experiment consisted of three treatments: 1) water (non-PS), 2) PS, and 3) PS combined with wood biochar (PS+WB). The PS+WB treatment resulted in the maintenance of elevated soil water content during the experimental period. The PS+WB treatment significantly enhanced soil nitrogen retention compared to PS alone, maintaining higher total N and NH₄⁺-N levels while reducing NO₃⁻ -N accumulation. Wood biochar application also leds to substantial reductions in NH₃ and N₂O emissions, mitigating environmental N losses. The PS+WB treatment resulted in an improvement of shoot biomass, crude protein content, and total digestible nutrients, indicating enhanced forage quality. The increased soil moisture content in PS+WB further contributed to plant growth benefits. These findings demonstrate that wood biochar is an effective amendment for improving nitrogen retention, reducing gaseous N emissions, and enhancing crop productivity in PS-amended soils.

This case study with 12 Korean high school emergent bilinguals (K-emergent bilinguals) illustrates how the pedagogical concept of translingual dialogic webbing can be conceptualized based on theories of dialogism and translanguaging. Through a concrete case of classroom activities using a picturebook, the Rough Patch, this article shows how the pedagogical concept of translingual dialogic webbing can be conceptualized and materialized in Korean high school English language teaching classrooms (Korean ELT). K-emergent bilinguals’ translingual classroom discussions as well as translingual and multimodal written responses revealed that translingual dialogic webbing could help Kemergent bilinguals draw on their available meaning making resources, including Korean, English, semiotic modes, cultural knowledge, and experiences, to navigate and construct more nuanced meanings with creativity and critical insights across time and space. By bridging translanguaging and dialogism, this study addresses the critical need for linguistic inclusivity and adaptability in Korean ELT, while embracing students’ diverse ideas, creativity, and the multilingual and multimodal realities of today.

This paper addresses a scheduling problem aimed at minimizing makespan in a permutation flow shop with two machines and an inspection process that must be conducted at least once every certain number of outcomes from the first machine. A mathematical programming approach and a genetic algorithm, incorporating Johnson's rule and a specific mutation process, were developed to solve this problem. Johnson's rule was used to generate an initial population, while the mutation process ensured compliance with the inspection constraints. The results showed that within a computation time limit of 300 seconds, the mathematical programming approach often failed to provide optimal or feasible solutions, especially for larger job sets. For instance, when the process times of both machines were similar and the inspection time was longer, the mathematical programming approach failed to solve all 10 experiments with just 15 jobs and only had a 50% success rate for 100 jobs. In contrast, the proposed genetic algorithm solved all instances and delivered equal or superior results compared to the mathematical programming approach.
