This study proposes a weighted ensemble deep learning framework for accurately predicting the State of Health (SOH) of lithium-ion batteries. Three distinct model architectures—CNN-LSTM, Transformer-LSTM, and CEEMDAN-BiGRU—are combined using a normalized inverse RMSE-based weighting scheme to enhance predictive performance. Unlike conventional approaches using fixed hyperparameter settings, this study employs Bayesian Optimization via Optuna to automatically tune key hyperparameters such as time steps (range: 10-35) and hidden units (range: 32-128). To ensure robustness and reproducibility, ten independent runs were conducted with different random seeds. Experimental evaluations were performed using the NASA Ames B0047 cell discharge dataset. The ensemble model achieved an average RMSE of 0.01381 with a standard deviation of ±0.00190, outperforming the best single model (CEEMDAN-BiGRU, average RMSE: 0.01487) in both accuracy and stability. Additionally, the ensemble's average inference time of 3.83 seconds demonstrates its practical feasibility for real-time Battery Management System (BMS) integration. The proposed framework effectively leverages complementary model characteristics and automated optimization strategies to provide accurate and stable SOH predictions for lithium-ion batteries.

This study was conducted from 2022 to 2024 at the Grassland and Forage Crops Division, National Institute of Animal Science (RDA), in Cheonan, Korea, to develop a medium-maturing variety of Italian ryegrass (Lolium multiflorum Lam.). The newly developed tetraploid cultivar, named ‘Spider’, is characterized by its green leaves, semi-erect growth habit in late autumn, and erect growth habit in mid-spring. With a heading date of May 16, ‘Spider’ is classified as a medium-maturing variety. Compared to the control cultivar ‘Kowinmaster’, ‘Spider’ has a 1.0 mm wider leaf blade, a 1.6 cm longer leaf blade, and is 5 cm taller in plant height. Its dry matter yield (10,169 kg/ha) is significantly higher than that of ‘Kowinmaster’ (p<0.05). The crude protein content of ‘Spider’ is 10.4%, which is 0.2% higher than that of the control. Additionally, ‘Spider’ has a neutral detergent fiber (NDF) content of 49.5% and an acid detergent fiber (ADF) content of 26.6%, showing a 2.2% lower NDF and a 0.2% higher ADF compared to ‘Kowinearly’.

This study investigated the flowering response of three Korean native Aster species, namely A. hayatae, A. spathulifolius, and A. koraiensis, to varying photoperiods. Three-month-old plants propagated from cuttings were grown under four different photoperiods: 9, 12, 14, and 16 h. Aster hayatae flowered under all conditions, with flowering rates of 92%, 85%, 65%, and 27% under 9-, 12-, 14-, and 16-h photoperiods, respectively. Flowering in A. hayatae was promoted by shorter photoperiods, classifying it as a facultative short-day plant. Aster spathulifolius flowered only under 9- and 12-h photoperiods, with no significant difference between these treatments, suggesting that the species is an obligate short-day plant. However, given the low A. spathulifolius flowering rates of 27% and 13% under 9- and 12-h photoperiods, respectively, further research is required. Aster koraiensis did not flower under any photoperiod, possibly due to vernalization requirements or juvenility. These findings offer valuable insights into the photoperiodic flowering responses of these three Korean native Aster species, enhancing our understanding of their ecological traits and potential horticultural applications.

본 연구는 절화 장미‘All For Love’에 대해 과산화초산 (peracetic acid, PAA)의 보존용액 적용 가능성과 적정 처리 농도를 구명하고자 수행되었다. 보존용액 처리는 Distilled water(DW), PAA 50, 100, 200μL·L-1, FloraLife 1%로 하였 다. 절화수명은 대조구 DW(5.27일)에 비해 PAA(5.87~6.20 일)와 FloraLife(5.87일) 처리구에서 절화수명 연장효과가 있었 다. 모든 처리구에서 80% 이상 꽃목 굽음(Bent neck)과 20% 이상 꽃잎 청변화(Blueing) 현상이 나타났다. 화색 변화율과 잎의 엽록소 함량은 처리간 차이가 없었다. 화폭변화율의 경 우, DW(135%)보다 PAA 50μL·L-1(155%), 100μL·L-1(154%), 200μL·L-1(161%) 처리구에서 높은 개화율을 보였다. 상대생체 중은 DW와 FloraLife 처리구에서는 2일, PAA 처리구에서는 3일까지 증가 후 감소하였다. 수분균형은 DW에서 가장 빠르게 (-)의 값을 나타냈고, PAA 50μL·L-1 처리구에서 가장 길게 수분 균형이 유지되었다. PAA와 FloraLife 처리구에서 보존용액과 줄기 절단면 모두 세균이 검출되지 않았다. 결론적으로 PAA 50μL·L-1 처리는 DW에 비해 장미의 절화수명 연장 및 품질 유지에 효과적이었다.

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.

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.

A 13-year-old female lion underwent a simple mastectomy for a rapidly growing abdominal mass, confirmed as mammary adenocarcinoma after histopathological examination. 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.
