Galaxy evolution studies require the measurement of the physical properties of galaxies at different redshifts. In this work, we build supervised machine learning models to predict the redshift and physical properties (gas-phase metallicity, stellar mass, and star formation rate) of star-forming galaxies from the broad-band and medium-band photometry covering optical to near-infrared wavelengths, and present an evaluation of the model performance. Using 55 magnitudes and colors as input features, the optimized model can predict the galaxy redshift with an accuracy of σ(Δz/1+z) = 0.008 for a redshift range of z < 0.4. The gas-phase metallicity [12 + log(O/H)], stellar mass [log(Mstar)], and star formation rate [log(SFR)] can be predicted with the accuracies of σNMAD = 0.081, 0.068, and 0.19 dex, respectively. When magnitude errors are included, the scatter in the predicted values increases, and the range of predicted values decreases, leading to biased predictions. Near-infrared magnitudes and colors (H, K, and H −K), along with optical colors in the blue wavelengths (m425–m450), are found to play important roles in the parameter prediction. Additionally, the number of input features is critical for ensuring good performance of the machine learning model. These results align with the underlying scaling relations between physical parameters for star-forming galaxies, demonstrating the potential of using medium-band surveys to study galaxy scaling relations with large sample of galaxies.

본 연구는 지난 10여년간 고려대학교 및 한국과학기술연구원(KIST)에서 AMS를 이용하여 측정된 우주선유발 동위원소 10 Be의 준비 및 측정 과정을 다룬 보고서이다. 총 2 4세트의 표준물질과 107개의 Blank시료가 분석되었으며, 2017년 이후 표준물질의 측정 재현성이 크게 향상되어 국제적인 주요 실험실의 결과와 비교할 만한 수준의 성과를 보였다. 그러나 Blank 값은 사용된 9 Be 캐리어의 종류 및 석영 추출 과정과 AMS 측정 세팅 등 실험 조건에 따라 영향 을 받는 것으로 나타났으며, 이는 잠재적인 오염원을 체계적으로 추적하고 관리할 필요성을 시사한다. 본 연구는 10 Be Background 값을 줄이는 것이 우주선유발 동위원소 연구의 범위를 넓히는 데 중요한 역할을 함을 강조한다. 낮은 Background 값은 상대적으로 최근에 형성된 지형이나 오랜 시간 매몰되어 방사성 핵종이 상당량 감소한, 저준위 10 Be 지형의 연대측정을 가능하게 한다. 향후 연구에서는 실험 과정을 개선하고 가중평균 계산법 등의 새로운 통계적 방법을 도입하여 측정 오차를 최소화하는 데 중점을 둘 예정이다. 본 연구는 다양한 시간적 및 공간적 규모에서 지구표면과학 연구를 발전시키기 위한 우주선유발 동위원소 분석의 기반을 제공한다.

We previously reported that pyridoxine and its derivatives exert antidiabetic effects by alleviating postprandial hyperglycemia via inhibition of carbohydrate-hydrolyzing enzymes in normal sprague–dawley (SD) rats. In this study, we aimed to further evaluate whether long-term pyridoxal supplementation decreases the blood glucose levels using SD rats. SD rats were randomly assigned to groups fed a high-carbohydrate diet (66.1% cornstarch) with or without pyridoxal (4%) for 36 days. Changes in body weight, blood glucose levels, and food intake were measured daily for 36 days. Dietary supplementation with pyridoxal significantly decreased the blood glucose levels (P<0.001) and body weight (P<0.001) in mice. Glycated hemoglobin (HbA1c) levels, which are good indicators of plasma glucose concentrations over prolonged periods, were also significantly decreased over five weeks (P<0.001). Similarly, dietary treatment with Acarbose ® (0.04%), a positive control, also significantly decreased the blood glucose and HbA1c levels and body weight. Overall, our findings suggest that pyridoxal inhibits weight gain and alleviates postprandial hyperglycemia by decreasing glucose absorption and HbA1c levels.

진저 비어는 생강과 설탕을 이용한 발효 음료로, 가볍 게 탄산화된 특유의 매운맛이 특징이며, 주로 가정에서 직 접 만들어진다.

Refractory materials, such as molybdenum and niobium, are potential candidates for cladding material due to their high melting temperatures and desirable mechanical properties at higher temperatures than those of zirconium alloys. However, refractory materials have low resistance to oxidation at elevated temperatures. Therefore, this study examined silicide or aluminide surface coatings as protection against rapid oxidation of refractory materials at elevated temperatures for a potential accident-tolerant fuel cladding. Silicide or aluminide layers were formed on refractory metal substrates by using the pack cementation method. The steam oxidation behavior of both coated and uncoated samples was compared by thermogravimetric analysis at 1200°C. The weight changes of the coated samples were greatly reduced than those of uncoated samples. Microstructural analyses demonstrated that the silicide and aluminide layers were oxidized to form a protective surface oxide that prevented rapid oxidation of the refractory substrate at elevated temperatures.

Wheat (Triticum aestivum L.), a significant cereal crop from the Gramineae family, serves as a vital source of protein, essential minerals, B-group vitamins, and dietary fiber. However, its productivity is often hindered by issues such as poor seed germination, which can adversely affect yield and crop quality. This study investigated the effects of different silicon concentrations and priming durations on wheat germination and seedling growth. Analysis of variance revealed that silicon treatment significantly influenced key parameters of germination and growth, including germination percentage (GP), germination index (GI), vigor index (VI), radicle length (RL), plumule length (PL), and seedling dry weight (SDW). Priming with silicon at a concentration of 1 mM resulted in notable improvements, increasing GP, GI, VI, RL, and PL by 10.6%, 65.5%, 29.4%, 18.6%, and 28.6%, respectively, after 6 hours of priming. Certain germination traits demonstrated strong positive correlations, particularly GP and GI (r = 0.96) and VI and RL (r = 0.94), after 4 hours of priming. These improvements in seed germination and seedling development may result from enhanced water uptake, stimulated cell division, and increased hydrolytic enzyme activity, which facilitate the mobilization of seed reserves and accelerate the growth of embryonic tissues.

Cherry tomato (Solanum lycopersicum L,. var. cerasiforme Mill.) is small fruits with a bright red color resembling a cherry and having an excellent taste, sweet and juicy ambience. So far, no cherry tomato variety was registered in Ethiopia. Consequently, six genotypes were imported from National Institute of Horticulture and Herbal Sciences (NIHHS), Rural Development Administration (RDA) Republic of Korea, and field experiment was conducted in RCBD with three replications at six Ethiopian testing sites, with irrigation, during off-seasons of 2021 and 2022 to identify high yielding, well adapted and good quality varieties. The overall analysis of variance across locations and years showed non-significant difference among the genotypes for marketable and total yields. But separate analysis for each site has revealed significant differences among genotypes at Melkassa, Koka, Adami- Tulu and Fogera, unlike that of Kulumsa and Woramit. There were significant differences (P < 0.05) among these genotypes for fruit numbers per plant, average fruit weight, fruits per cluster, plant height, skin thickness, juice volume and total soluble solid. Wonhong No.3 gave higher marketable (24.49 t/ha) and total (26.19 t/ha) yields, and generally Wonhong Nos.3 and 5 had higher yields and good qualities across these tested locations and years. Hence, Wonhong No.3 (designated as Jorgie-1) was registered for its higher yield, non-cracking, good TSS and color, while Wonhong No.5 (renamed as Jorgie-2) was preferred for its smaller fruit size, reasonable yield and quality (TSS, color, non-cracking). Hence, both varieties were officially registered in 2023 season for commercial production in different agro-ecologies of Ethiopia, and they are believed to add more economic and nutritional values for the tomato producers and the consumers. They can also support the intensification of tomato cultivation in peri-urban and urban agriculture, where demands and thus government focus are increasingly growing.

This study investigated the growth dynamics of Lilium miquelianum bulb scales cultured in four different media formulations: Full Murashige-Skoog (FMS), Half Murashige-Skoog (HMS), Anderson Vitamin (AV), and Knudson Vitamin (KV). Bulb scales were collected from native populations on Jeju Island, Korea, and cultured in vitro for 12 weeks. Growth parameters, including bulb area and scale count, were measured at 3-week intervals. Statistical analyses revealed significant differences in growth rates across media types and time points. FMS consistently demonstrated the highest growth rates and final bulb area and scale count, while KV exhibited the lowest performance. Heatmap analysis showed that FMS achieved the highest weekly growth rates in most time points, with HMS showing comparable performance during early growth stages. Individual sample growth rates varied within media, highlighting the influence of both external and internal factors on growth. Correlation analysis revealed a positive association between bulb size and scale quantity, with FMS exhibiting the strongest relationship. These findings emphasize the importance of appropriate media selection for optimal L. miquelianum propagation, with FMS being the most suitable for extended cultivation. This research provides valuable insights for improving propagation efficiency and conservation efforts of L. miquelianum.

곤충호텔은 곤충이 서식할 수 있도록 인위적으로 만든 구조 물로서 정원이나 텃밭 등 다양한 곳에서 활용되고 있다. 하지만 식생유형, 재료, 설치 방식 등에 따른 곤충 유입 효과에 대한 검증은 부족하며, 국가 또는 지역에 따른 곤충의 종류와 생육환 경이 다름에도 불구하고 곤충호텔에 대한 국내 연구는 전무한 실정이다. 따라서 본 연구에서는 국립수목원을 대상으로 구체적 인 식생유형 및 재료에 따른 유입 곤충 특성을 확인하고, 국내 실정에 맞는 효과적인 곤충호텔 설치 및 관리방안에 대한 기준 을 제시하고자 하였다. 조사구는 세 가지 식생유형(초지, 침엽수 림, 활엽수림)으로 구분하였으며, 각 식생의 조사구에 두 가지 재료(참나무, 잣나무)를 활용한 곤충호텔을 설치하였다. 조사는 2년동안(2022~2023) 진행되었으며, 매년 4~9월까지 주 1회 씩(총 48회) 곤충호텔의 유입 곤충을 직접 채집하였다. 곤충호 텔에서 채집된 곤충은 총 9목 46과 129종 3,057개체로, 2022 년에는 7목 34과 85종 1,750개체, 2023년에는 8목 35과 77종 1,307개체가 출현하였다. 연도별로 비교하면 1차년도에 유입 된 곤충의 개체수가 2차년도 보다 약 1.3배 많았고, 재료의 부식 에 따른 곤충의 구성도 달라졌다. 식생유형에 따라 구분하면 기간에 상관없이 활엽수림에서 유입 곤충이 가장 많았고, 침엽 수림에서 가장 적었다. 또한 재료에 따른 구분에서는 참나무가 잣나무보다 유입 곤충이 많았다. 참나무의 경우 유입 곤충의 연도별 차이가 적은 반면, 잣나무는 1년차에 비해 2년차에 약 2.3배 줄었다. 상관분석과 계층적 군집분석을 통한 곤충의 유입 특성은 식생유형보다는 재료의 영향이 큰 것으로 확인되었고, 식생유형만 비교했을 경우 초지에 비해 활엽수림과 침엽수림의 유사성이 높았다. 결론적으로 생물 다양성 증진을 목적으로 곤 충호텔을 설치하고자 한다면 초지나 활엽수림에 참나무 재료를 사용하는 것이 유리하며, 잣나무 재료를 이용한다면 1년 주기로 재료 교체가 필요할 것으로 판단된다. 하지만 특정 재료를 선호 하는 곤충의 기주특이성이 확인되었기 때문에 다양한 종류의 재료를 같이 사용하는 것도 하나의 방법이라고 사료된다. 향후 이를 기반으로 전시원에서 실질적으로 활용할 수 있는 곤충호텔 모델 개발로 확대해 나갈 예정이다.

전세계적으로 50여종이 알려져 있는 Adrapsa속은 지금까지 한국에서는 2종이 알려져 있다. 이 연구에서는 Adrapsa notigera (Butler)를 국내 에서 처음으로 보고한다. 이 종의 형태학적 특징과 유사종과의 차이, 분포지역, 성충 및 생식기 사진을 제공하며 유전학적 정보를 통하여 속 내 다른 종과의 분류학적 관계에 대해서도 고찰한다.

국립수목원 전시원의 지속가능하고 친환경적인 관리를 위하 여 유기물 멀칭재 처리에 대한 잡초 억제 효과를 조사하였다. 대표적 잡초인 쑥군락과 바랭이군락을 대상으로 고정방형구 (1×1㎡)를 3반복 설치하였다. 처리구의 유기물 멀칭재는 5가지 재료로 활엽수 우드칩, 침엽수 바크, 갈참나무 낙엽, 메타세쿼이 아 낙엽, 칠엽수 과피를 사용하였다. 멀칭재 중에서 갈참나무 낙엽, 활엽수 우드칩, 칠엽수 과피가 비교적 잡초 억제 효과가 높은 것으로 나타났다. 갈참나무 낙엽은 지중 온도를 낮게 유지 하는 효과가 상대적으로 좋았기 때문에 토양의 보습 효과가 뛰 어날 것으로 판단된다. 유기물 멀칭재 처리는 일년생식물의 발 생은 억제하고, 지중식물 및 반지중식물의 생육에 도움을 주는 효과가 있었다. 멀칭재의 무게보다 재료에 의한 빛 차단 면적이 잡초를 억제하는 주된 요인이었다. 본 연구 결과는 국립수목원 전시원에서 발생하는 부산물을 활용한 친환경적 관리 방안 수립 에 활용될 것이며, 향후 잡초의 발생 시기에 따른 멀칭 시기 및 유기물 멀칭재의 유지 관리에 대한 추가적인 연구가 필요하다.

Humic acids (HA), with their irregular polymeric structures and largely existing in grassland, present challenges in quality control due to significant variations in biological activities depending on extraction sources. To address this, we explored industrial byproducts as potential alternatives mimicking HA-like bioactivities. This study evaluates sulfite lignin, a byproduct of the pulp industry, as an eco-friendly biostimulant for enhancing plant growth and stress tolerance. Sulfite lignin demonstrated HA-like bioactivities, promoting seed germination and salt stress tolerance in Arabidopsis thaliana. Germination assays revealed that sulfite lignin significantly improved radicle and cotyledon emergence, particularly at low concentrations (8.6 mg L⁻¹), outperforming HA and kraft lignin. Additionally, under salt stress conditions, sulfite lignin-treated plants exhibited healthier phenotypes and maintained higher chlorophyll content compared to control treatments, similar to HA and kraft lignin. The findings highlight sulfite lignin as a promising, sustainable, and cost-effective biofertilizer, effectively replicating HA's biological functions while leveraging industrial byproducts.

This study was conducted to investigate changes in the productivity of Italian ryegrass seeds according to the timing of harvest after heading in the southern region. The Italian ryegrass variety ‘Greencall’ was sown in Jinju, Gyeongsangnam-do, in the fall of 2022. Four harvest timings were tested (30, 40, 50, and 60 days after heading), with a randomized complete block design and three replicates. Sowing in the test plots took place on October 10, 2022, and harvesting was carried out from 30 days after heading on May 18 to 60 days. The plant height was the longest (99.1 cm) in the plot harvested 30 days after heading and decreased as the harvest was delayed. No significant differences were observed among treatments in terms of lodging resistance, disease resistance, and cold resistance. However, lodging severity increased over time after heading (7∼9). Disease incidence was also higher in plots harvested 50 and 60 days after heading. The length of the spike was shortest (38.76 cm) in the plot harvested 50 days after heading, and the number of seeds per spike was the lowest (42 seeds/spike) in the plot harvested 60 days after heading. The dry matter content of seeds increased with the delay in harvest, while dry matter yield decreased, with the lowest yield observed in the plot harvested 40 days after heading (3,031 kg/ha, p<0.05). The dry matter content of seed straw was highest at 75.73% in the plot harvested 50 days after heading and dropped to 34.99% 60 days after heading due to rainfall. The dry matter productivity of the seed straw was the lowest in the plot harvested 40 days after heading. The feed value of the seed straw also decreased with delayed harvest, with an average RFV (Relative Feed Value) of 91. In conclusion, the optimal harvest timing for fall-sown Italian ryegrass intended for seed production in the southern region appears to be 30 days after heading.

Afoxolaner is an insecticide and acaricide that belongs to the isoxazoline chemical compound group. it has been used as an active pharmaceutical ingrdient in veterinary medicine to treat fleas and ticks in dogs. When patents expire between 2026 and 2066, it is expected that many products will be applied for approval as generic products, and reserch to establish accurate quality control methods must be conducted and managed. HPLC method was developed for the quantitative and qualitative of afoxolaner in veterinary medicinal products. The separation of active constituents for afoxolaner was achieved on a RP18 (4.6 x 150 mm, 5 μm) column using Water : Acetonitrile : MeOH (25:30:45 v/v/v) as mobile phase, with UV detection at 245 nm. The method was validated for specificity, linearity, accuracy and precision. All calibration curves showed good linearity (R2 of 0.999) within the concentration ranges (12.5 to 400 μg/mL). For accuracy, the recovery rate was calculated by spiking three concentrations of standard into the sample blank. The recovery rate was calculated to be 99.70~100.58%. Precision was measured 9 times repeatedly through intra-day, inter-day tests using standard. It showed excellent precision by satisfying the relative standard deviation of less than 2% both intra-day and inter-day. Limit of detection (LOD) and limit of quantitation (LOQ) were 2.0 μg/mL and 6.1 μg/mL, respectively. This method was successfully applied to analyzing afoxolaner drugs distributed in Korea. The HPLC method described in this study is accurate and reproducible and could be applied for the analysis of veterinary drugs of afoxolaner.

Background: Stroke patients commonly experience functional declines in balance and gait due to decreased muscle strength and coordination issues caused by brain damage. Through repetitive training, robot-assisted gait training (RAGT) can aid in promoting neuroplasticity in stroke patients and help them acquire effective gait patterns. Additionally, convalescent rehabilitation hospitals help to ensure rapid recovery through intensive rehabilitation training. Objects: This study investigated the effects of RAGT frequency on gait and balance recovery in stroke patients in convalescent rehabilitation hospitals, providing data to optimize rehabilitation efficiency, enhance functional recovery, and support the development of personalized strategies to ensure safer and more rapid returns to daily life. Methods: This study compared the frequency of RAGT by analyzing a group receiving two units of RAGT per day for 5 days per week with a group receiving two units of RAGT per week as part of a comprehensive rehabilitation program, totaling 16 units daily, in a convalescent rehabilitation hospital. Results: In the 10-minute walking test, statistical significance was observed both within and between groups, whereas the Functional Ambulation Category, Fugl-Meyer Assessment–lower extremities, Berg Balance Scale, and timed up-and-go tests showed significance only within groups. Conclusion: End-effector RAGT and traditional gait training significantly improve gait ability, balance, and lower limb function in stroke patients.

Silage inoculants, which include beneficial microorganisms like lactic acid bacteria (LAB), play a vital role in modern silage production by enhancing fermentation quality. This study evaluated the effectiveness of various commercial inoculants on the fermentation dynamics of Italian ryegrass silage over 45 days. The treatments included a control group and five inoculant formulations: T1 (Lactiplantibacillus plantarum), T2 (Lactiplantibacillus plantarum and Pediococcus pentosaceus), T3 (Lactiplantibacillus plantarum and Pediococcus pentosaceus and Lactiplantibacillus buchneri), T4 (Lactiplantibacillus plantarum and Lactiplantibacillus acidophilus and Lactiplantibacillus bulgaricus), and T5 (Lactiplantibacillus plantarum and Pediococcus pentosaceus and Enterococcus faecium). After 45 days, all treatment groups exhibited significantly higher crude protein (CP) content compared to the control group (80.64 g/kg dry matter (DM), p<0.05). Treatments T2 and T5, which incorporated combinations of Lactiplantibacillus plantarum, Pediococcus pentosaceus and Enterococcus faecium, showed higher CP contents at 105.53 and 107.05 g/kg DM, respectively. The inoculated silages also demonstrated a rapid pH reduction within the early days, with Lactiplantibacillus plantarum in T1 reducing the pH to 4.0 within four days. Additionally, inoculated treatments had significantly higher lactic acid levels than the control (67.96 g/kg DM, p<0.05), and T3 (Lactiplantibacillus buchneri) produced higher acetic acid levels (16.07 g/kg DM, p<0.05) than other inoculants. The control group also had a notably higher ammonia nitrogen content. In conclusion, while single-strain inoculants like Lactiplantibacillus plantarum are effective for rapid acidification, the use of combined bacterial strains can further enhance silage quality by improving lactic acid fermentation and nutrient preservation, particularly in treatments like Lactiplantibacillus plantarum and Pediococcus pentosaceus and Lactiplantibacillus buchneri and Enterococcus faecium.
