Limited fashion products serve as a strategy for demonstrating the brand’s vitality and presence by satisfying the emotional needs of consumers seeking to escape from the boredom of similar products. The MZ generation values unique experiences and desires to purchase rare and unique products. Accordingly, the fashion industry prioritizes launching limited fashion products that emphasize artistry and can convey different values compared to existing products. The open-run phenomenon, characterized by people waiting in line before the store opens and then running to the store to purchase these limited products as soon as the store opens, is rapidly emerging as a consumer trend in our society. This study explored the impact of fashion consumers’ psychological factors-that is, FOMO, brand attachment, and need for uniqueness-on their open-run intention for limited fashion products. An online survey was administered to test the research hypotheses on Korean consumers, and 300 responses were statistically analyzed using the SPSS 28.0 program. The results revealed that FOMO, brand attachment, and the need for uniqueness significantly increased open-run intention for limited fashion products. Furthermore, consumers’ fashion involvement appeared to have a significant positive moderating effect on FOMO, brand attachment, and open-run intention. However, it did not substantially impact the effect of the need for uniqueness on open-run intention.

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.

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.

To explore the origins of Korean food culture, the results of archaeological excavations of pottery relics from the early Neolithic period on the Korean Peninsula were examined, and the changes in the form and usage of the potteries in the stratified layers of shell mounds were investigated. The findings revealed that pottery was made for use as cooking vessels, fermentation crocks, and storage jars. Advances in materials. shapes, and techniques reflected efforts to produce larger vessels that were more durable, water-resistant, and heat-resistant. The consequent food items developed were traced, the biochemical changes in cooking pot and fermentation crock were estimated, and the nutritional and hygienic contributions of the early pottery to the Neolithic people were evaluated. The primitive pottery culture era is considered an important starting point that determined the food culture of Koreans. It is argued that the production of traditional Korean cuisine, jjigae, and fermented foods such as kimchi, jeotgal and makgeolli began by using pottery. As a result, the food availability of the early Neolithic period greatly expanded, and the nutrition and hygiene of Neolithic people were drastically improved, leading to the beginning of sedentary life and agriculture, and the formation of ancient Northeast Asian states.

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 study aimed to estimate the accumulated temperature requirements for phenological changes in Lilium. Eight cultivars of three lily types were cultivated in open field conditions for phenological observations based on floral organ development. Growing degree days (GDD) requirements for phenological changes were calculated and verified using Lilium LA hybrid ‘Serrada’ under greenhouse conditions. Lilium Oriental hybrids exhibited higher GDD requirements compared to Lilium FA and LA hybrids for their phenological development. Estimations of phenological change dates in greenhouse cultivation were accurate within 1–3 days. These results provide a reliable description for predicting lily development stages across diverse cultivation environments by quantifying the accumulated temperature requirements for key phenological events.

Mammary tumors are common in domestic cats but less frequently reported in African lions. This report presents the first documented case of mammary adenocarcinoma in an African lion in South Korea. The mass was successfully excised through stable anesthesia and surgery. This report adds to the limited literature on mammary tumors in large felids and discusses the need for tailored management strategies.

This research, grounded in the extended technology acceptance model, aimed to explore the relationships among factors influencing Korean EFL learners’ acceptance of ChatGPT for English learning in a voluntary usage context. To this end, a questionnaire was distributed to college students who had used ChatGPT for language learning, utilizing a convenience sampling method. A total of 400 responses were analyzed to test hypotheses using structural equation modeling (SEM). Findings revealed that learners’ perceived usefulness significantly predicted their intention to continue using ChatGPT, while perceived ease of use did not. Moreover, learners’ result demonstrability was found to be a predictor of perceived usefulness, whereas subjective norm was not. Both playfulness and output quality significantly influenced learners’ perceived ease of use. This study identified key factors that could enhance EFL learners’ acceptance of ChatGPT by improving perceptions of usefulness and ease of use, offering valuable insights for integrating ChatGPT into English education.

For risk assessment of spent nuclear fuel (SNF) transportation, it is necessary to calculate the damage ratio of SNF rods loaded in the cask. Due to the complexity in the geometry and material properties of SNF, it is impractical to analyze the detailed behavior of every fuel rod and assembly in a single cask model. This study presents a framework for performing cask-level analysis by sequentially simplifying the fuel rods and spent fuel assemblies for fuel damage ratio (FDR) calculation. Using the simplified fuel rod model developed in previous studies, we constructed a CE 16×16 fuel assembly model and presented a methodology to simplify the CE 16×16 assembly model into cuboids. Cask drop analyses were performed to validate the similarity of the detailed CE 16×16 model and the simplified model. Using the proposed simplified models, a procedure for quantifying the bending load and pinch load applied to the fuel rods during the drop impact is presented. The FDR can then be calculated by comparing the quantified loads with their respective failure criteria. Through a case study, the feasibility of the developed framework for systematic and accurate FDR calculation was effectively demonstrated.

The swelling capacity of bentonite buffers is vital in high-level radioactive waste (HLW) repositories, as it minimizes groundwater infiltration, prevents nuclides from reaching the biosphere, and stabilizes the HLW canisters. As swelling capacity is a function of temperature, understanding bentonite’s behavior at approximately 100°C (its presumed upper limit) is essential. However, research on this subject has been scarce. Hence, this study explored the effects of thermal treatment of Ca-bentonite at 105°C under injected water pressures. The results suggest a 19% reduction in “swell index” and a 35%–36% decrease in the total pressure in thermally treated bentonite. The heated samples demonstrated higher hydraulic conductivity than the non-heated ones, indicating potential performance deterioration in controlling the fluid movement. Furthermore, the injected water pressure (base pressure) was not fully transmitted to the sample owing to the difference between the base and back pressures, leading to variations in the total pressure despite maintaining a constant differential pressure. Thus, the results demonstrated a degradation in bentonite’s swelling capacity and its compromised role in safe HLW disposal, when subjected to treatment at 105°C. The insights from this research can assist in HLW repository design, while highlighting the need for further research into bentonite’s performance.

Securing the safeguardability of a reprocessing process for spent nuclear fuels (SNFs) is imperative. Particularly, the quantity of special nuclear materials inside SNFs must be estimated with the highest achievable precision. Unlike aqueous reprocessing, pyro-processing involves handling input materials in a solid state. Hence, partially extracted samples analyzed by destructive assay (DA) should maintain an acceptable level of representativeness. In this study, a representative sampling method widely applied in the pharmaceutical industry was adopted for homogenization in the head-end process of pyro-processing. By employing representative sampling, specifically based on the mechanism of the rotary riffler, the overall process of homogenization prior to DA analysis was simplified, and less probable hold-up that could contribute to materials unaccounted for (MUF) would be expected. The resulting Pu sampling uncertainty was confirmed to be less than 1% (for ≥ 1,000 μm particle size and ≤ 5 kg sample mass), ensuring sufficient control of Pu accounting uncertainty at a reasonably low level (≤ 1%). Thus, representative sampling can be a competitive alternative to previously suggested methodologies.

자발적 지역 검토(VLR)는 도시 차원에서 지속가능발전목표(SDGs) 이행 현황을 자발적으로 점검하는 보고서이자 SDGs의 현지화 과정이다. VLR을 통해 도시의 지속가능발전 리더십을 확인하고, 지방정부와 도시 구성원이 2030 의제 목표에 대한 진행 상황을 평가하고, 가속화 방안을 모색하는 데 유용한 도구가 된다. 또한, VLR은 SDGs 인식을 제고하고, 파트너십을 활성화하며 지역 차원의 행동을 촉진하여 도시가 사회・경제・환경 발전을 위한 일관된 미래 비전을 제시하도록 돕는다. 나아가 도시 민주주의 전략을 글로 벌 의제와 연결하는 중요한 역할을 한다. 본 연구는 대한민국에서 아직 널리 알려지지 않은 VLR의 성공적 정착과 확산을 목표로 한다. 이를 위해 VLR의 개념, 역사, 주요 논의, 효과 및 성공 요인을 분석하고, 도시 민주주의와 이를 위한 다단계 거버넌스 및 SDGs 확산의 관련성을 규명하고자 한다. 또한 도시 VLR 적용 과정에서 예상되는 과제를 제시하며, 한국적 VLR 운동에 대한 관심을 높이고 실질적 적용을 촉진하고자 한다.

Endosymbionts of the genus Buchnera, which belong to γ-Proteobacteria, reside in specialized cells known as bacteriocytes. In this announcement, we present the complete genome sequence of Buchnera aphidicola (Aphis gossypii) isolated from Aphis gossypii with Plantago asiatica. The genome spans 628,098 base pairs and has a GC content of 25.4%. A total of 589 CDs, 32 tRNAs, and 3 rRNAs were predicted. Interestingly, the evolutionary rate of the endosymbiont's genome, inferred from intraspecific variations, may be slower than that of the host's mitochondrial genome.

In this study, we aimed to understand the effects of pest control on forest ecosystems by examining the populations of beetles, a bioindicator species, in pine wilt disease-affected areas. Density and diversity of beetles at the pest control (sites 1 and 2) and control (site 3) sites were compared. Site 1 contained 247 individuals of 11 species from 5 families, site 2 contained 461 individuals of 19 species from 9 families, and control site 3 contained 511 individuals of 19 species from 9 families. The following main species were collected from each site: 34 pine jewel beetles(Chalcophora japonica) in June, 23 red flat bark beetles(Synuchus cycloderus) in August, and 42 red flat bark beetles in September from site 1, 46 pine jewel beetles in June, 36 elegant beetles(Carabus jankowskii) in August, and 21 elegant beetles in September from site 2, and 31 red ground beetles(Coptolabrus smaragdinus) in June, 56 two-spotted dust beetles(Planetes puncticeps) in August, and 30 two-spotted dust beetles in September from site 3. Furthermore, diversity, evenness, and dominance indices were analyzed for all beetles collected from the pest control and control sites. Site 1 exhibited a diversity index of 0.706, evenness index of 0.711, and dominance index of 0.161. Site 2 exhibited a diversity index of 1.115, evenness index of 0.872, and dominance index of 0.097. Site 3 exhibited a diversity index of 1.101, evenness index of 0.861, and dominance index of 0.102. Similarity index was 47.4% between sites 1 and 2, 33.3% between sites 1 and 3, and 40.0% between sites 2 and 3.

This study investigates the effectiveness of self-correction in improving lexical stress placement among Korean English learners, a critical yet challenging feature for speakers of Korean, which lacks lexical stress contrasts. Grounded in Schmidt’s (1990) Noticing Hypothesis, the research compares the benefits of self-correction— where learners reflect on and correct their own pronunciation errors —with the shadowing technique. Forty-seven college students participated, with an experimental group practicing self-correction and a control group engaged in shadowing. Pre- and post-test analyses revealed that the self-correction group demonstrated significantly greater improvement, particularly with trisyllabic and tetrasyllabic words, while the shadowing group showed minimal change. These findings highlight self-correction’s role in promoting learner engagement, error awareness, and deeper cognitive processing, offering practical implications for pronunciation instruction that emphasizes learner autonomy and focused attention.

온실 내부 환경은 지역에 따라 외부 환경의 영향을 지속적으로 받는다. 본 연구는 몽골, UAE(아부다비), 호 주(퀸슬란드) 등 지역별로 구축된 한국형 스마트 온실의 환경 특성을 비교하고자 수행하였다. 몽골과 아부다비의 온실 모두 내외부 엔탈피 차이가 감소함에 따라 환기율이 증가하였다. 아부다비의 반밀폐형 온실에서는 10시부터 14시까지 평균 내부 기온이 외부 기온보다 약 7－10°C 낮았고 내부 VPD(12mbar)는 외부 VPD(56mbar)보다 4.6 배 낮았는데 이 결과는 포그 시스템 운영과 관련이 있는 것으로 보인다. 퀸즐랜드 온실의 경우, 내부 온도가 외부 온 도보다 11시 기준 약 3.81°C 높았고, 내부 엔탈피와 VPD가 외부 온도보다 높았으며, 내부와 외부의 엔탈피 차이가 증가함에 따라 환기율이 증가하였다. 이 결과로 엔탈피를 낮추는 것은 환기와, VPD를 낮추는 것은 포그 시스템 작 동과 관련이 있는 것을 알 수 있다. 또한, 작물 생육에 적합한 환경 조건을 효과적으로 관리하기 위해 엔탈피와 VPD 기반의 포그, 환기 또는 난방 시스템이 필요하다는 것을 알 수 있다.

This study analyzes the participants’ purchasing and wearing conditions of Jiu-Jitsu uniforms, identifying issues with current designs and proposing improvements. Data were collected from 160 participants through an online survey from April 15 to May 20, 2024. Frequency, cross-tabulation analyses, and one-way ANOVA were performed using SPSS 29.0. The survey included questions related to participants’ general information, uniform purchasing behavior, satisfaction with Jiu-Jitsu uniforms, preferred brands, and sizing, and fit satisfaction. The results revealed that most male participants were in their 30s, while female participants were in their 20s. A higher proportion of males were overweight, while females were likelier to have a normal BMI. Participants generally owned 3–6 uniforms, most purchases in the 160,000–200,000 KRW price range. International brands were preferred, and participants selected uniforms based on fit, quality, and design. The most common sizes were A1 and A1L, with overweight and obese participants tending to opt for additional size options. Key improvement areas included pants length and waist width. The findings highlight the need for unisex pattern designs for individuals in the B range (160–170cm) and patterns specifically designed for overweight males in the C range (170–180cm). This study provides valuable insights into Jiu-Jitsu uniform preferences and body typespecific requirements, offering foundational data for enhancing uniform design and functionality.
