        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.

        국내 수박(Citrullus lanatus) 품종의 발아율에 대한 Solid Matrix Priming(SMP)의 영향을 평가하였다. Micro cel-E가 SMP 처리에 가장 이상적인 matrix로 밝혀졌으며, 종자:matix:물의 비율은 10:5:10(w/w/w)로, 25°C 에서 3일 동안 처리했을 때 유근의 돌출없이 발아속도가 촉진되었다. SMP 처리 과정 동안 초기 4시간 동안의 수분 흡수율은 급격하게 증가했으며, 이후 72시간 동안은 더 느린 속도로 흡수되었고, 처리 마지막 시간까지 수분 흡수 율은 41%이었다. 발아 온도와 상관없이, SMP 처리된 종자는 발아 시간이 단축되면서 발아율이 향상되었다. 특히, 최적 발아 온도보다 낮은 온도에서 발아율이 높았다. 품종별 차이는 있었으나, 특히 ‘해찬꿀’과 ‘리코스위트’ 품종 에서 발아율이 유의미하게 증가하였다. 또한 일부 품종에서 SMP 처리 종자의 유묘출현율과 초장, 생체중이 무처 리에 비하여 증가한 값을 보였으며, SMP 처리로 종자의 발아속도 및 유묘활력을 증진시켜 우량 묘 확보가 가능한 것으로 판단되었다.

        Background/Aim: This study investigated the relationship between albumin-bilirubin (ALBI) grade and advanced liver fibrosis in patients with a history of gallstone disease and cholecystectomy, focusing on those diagnosed with metabolic dysfunctionassociated steatohepatitis (MASH) using the acMASH algorithm. Methods: Data from 566 subjects in the National Health and Nutrition Examination Survey 2017-2020 dataset were analyzed. MASH and advanced fibrosis (AF) were determined using acMASH and acFibroMASH algorithms, respectively. Liver stiffness measurement (LSM), ALBI grade, and other fibrosis indices were evaluated. Results: Of 566 subjects, 13 (2.3%) were diagnosed with MASH, and 65 (11.48%) had AF. MASH subjects showed significantly higher LSM values compared to non-MASH subjects (p=0.032). ALBI grade demonstrated weak positive correlations with LSM, FIB- 4, and acFibroMASH in non-MASH subjects. The AUROC for ALBI grade in identifying AF was 0.631 (95% CI 0.590-0.671). Multivariate analysis confirmed ALBI grade as an independent predictor of AF (odds ratio 0.193, 95% CI 0.1025-0.2837, p<0.001). Conclusions: ALBI grade shows potential as a non-invasive marker for advanced liver fibrosis in patients with a history of gallstone disease and cholecystectomy, particularly in those with MASH. Further studies with larger MASH cohorts are needed to validate these findings.

        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.

        Maturity at harvest is the key factor influencing storage life and the final quality of fruit. This study examined how the firmness of ‘Sweet Gold’ kiwifruit at harvest affects its post-ripening characteristics to create a maturity chart. Throughout the storage period, firmness decreased in all categories of fruit: hard, medium, and soft. ‘Soft’ fruits lost 40% of their firmness within 2 days after harvest, whereas ‘hard’ fruits remained firmer than soft fruits throughout the storage period and had the least soluble solids content, indicating a slower ripening progression. The acidity of ‘soft’ kiwifruit was very low from the day of harvest, suggesting that it was utilized as a respiratory substrate during ripening. The a-values (indicating redness) for ‘soft’ fruits gradually increased until day 6, stabilizing thereafter. ‘Soft’ fruits exhibited the highest ethylene production rate throughout storage. They showed a climacteric rise in ethylene on day 13, compared to ‘medium’ and ‘hard’ fruits, which exhibited increases on days 19 and 21, respectively. This data can help determine the optimal ethylene treatment duration for ripening ‘Sweet Gold’ kiwifruit. The firmness of ‘Sweet Gold’ kiwifruit at harvest is a crucial factor in determining its marketability and can effectively serve as a maturity index to estimate its shelf life.

        The recent release of contaminated water from the Fukushima Daiichi Nuclear Power Plant highlights the need for accurate tritium measurement, particularly near the minimum detectable activity (MDA) of 5 Bq·L−1 set by South Korea’s Nuclear Safety and Security Commission. This study aims to improve low-level tritium measurement accuracy by optimizing the region of interest (ROI) for quench curve determination. These adjustments are crucial for separating tritium signals from background noise. Quench standards were prepared and measured using a liquid scintillation counter (LSC). Three ROIs were analyzed to assess the impact of channel selection on measurement precision: A 20-148 channel range optimized via figure of merit (FOM) analysis, a 20-250 channel range covering tritium’s full beta spectrum, and a broad 1-1024 channel range. Quench curves were obtained by fitting the counting efficiency of each ROI to the quench standards. Tritium samples with six different activity levels were prepared, and their radioactivity was calculated using the quench curves. Selecting appropriate ROIs for quench curve determination is critical for measuring low-concentration tritium accurately. This approach reduces uncertainty and emphasizes reliable methods to improve the precision and consistency of tritium measurements.

        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.

        Increasing resource use is the primary motivator for the development of technology industries, which is leading to severe consequences, such as the release and disposal of radioactive waste containing radionuclides in the environment. Cesium (137Cs) is one of the most hazardous radionuclides in the environment. In particular, the steel manufacturing process produces hazardous waste in the form of electric arc furnace dust contaminated with 137Cs. In this study, the tolerances of five legume species to different activity concentrations of 137Cs in both seed germination and initial seedling growth were compared. To determine 137Cs tolerance, several parameters related to the growth and development of legumes were measured. Among the five legumes studied, Crotalaria juncea L. was the most 137Cs tolerant at 50,000 Bq·L−1. Sesbania javanica Miq. and Vigna mungo L. Hepper were moderately tolerant to 30,000 Bq·L−1 137Cs. After 10 days, the stress tolerance indices in all legume species decreased by more than 50% at activity concentrations greater than or equal to 20,000 Bq·L−1 137Cs. This approach allows the selection of desirable traits, making more-effective application possible in the phytoremediation of 137Cs through stress tolerance. In conclusion, legumes are promising candidates for the phytoremediation of environmental pollutants.

        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 relationship between changes in language learning beliefs and English proficiency among 41 Korean university students who participated in a short-term English program. Participants’ beliefs were assessed using the Beliefs About Language Learning Inventory (BALLI), and their proficiency was measured using the Test of English for International Communication (TOEIC). Frequency analysis, descriptive statistics, paired-sample t-tests, and correlation analysis were employed to analyze the data. The study found significant improvements in both listening and reading scores, and changes in beliefs varied with proficiency gains. Students with higher proficiency gains demonstrated improved confidence and self-efficacy, and decreased instrumental motivation, whereas those with lower gains exhibited minimal changes in beliefs. Correlation analysis revealed that belief shifts, such as reduced selfconsciousness and increased integrative motivation, were positively related to proficiency gains. These findings suggest the dynamic nature of learners’ beliefs and their potential impact on language learning outcomes, highlighting the importance of addressing belief systems in English language education.

        For centuries, humans have leveraged the health-promoting properties of plants for our well-being. While research has been conducted on numerous medicinal plants, the specific benefits of many species remain underexplored. Eupatorium Japonicum (EJ), a member of the Asteraceae family, has historically been consumed in Japan, South Korea, China, and Vietnam for its traditional use in soothing digestive issues. This study aimed to explore the radical scavenging and antiinflammatory efficacy of EJ extract using RAW 264.7 cells. The radical-scavenging effects were assessed using the DPPH and ABTS assays, where an anti-oxidative molecule in the test sample will react with a stable free radical in DPPH and ABTS causing discoloration. The anti-inflammatory efficacy was assessed using the nitric oxide (NO) assay in LPS-induced RAW 264.7 cells, where the amount of NO produced in response to infection was measured using Griess reagent. Reversetranscriptase polymerase chain reaction (RT-PCR) and real-time PCR were executed to confirm the anti-inflammatory activity by measuring the RNA levels of pro-inflammatory cytokines. The DPPH and ABTS assays revealed that EJ extract decreased oxidation in a concentration-dependent manner (7.8-1,000 μg/mL) compared to ascorbic acid and Trolox respectively. EJ extract significantly reduced NO production concentration independently. Furthermore, EJ extract showed no cytotoxic effects as determined through the MTT assay. RT-PCR and real-time PCR analyses revealed inhibition of mRNA expression of pro-inflammatory cytokines (iNOS, COX-2, TNF-α, and IL-6). Western blotting demonstrated EJ’s anti-inflammatory activity by reducing protein levels of iNOS, COX-2, TNF-α, and IL-6. These findings suggest that EJ extract exhibits anti-inflammatory activities and can be further evaluated in the future.

        This study examined the feeding behavior and growth performance of 31 Hanwoo steers (10 months old; 278 ± 36.13 kg) within a precision livestock farming system using Roughage Intake Control (RIC) units for real-time data collection. Feeding behavior traits were derived from RIC database data using R software, with subsequent analysis conducted using SAS software. The results indicated that the steers visited the feed stations every 31.12 ± 11.99 minutes, averaging 11 ± 3.37 visits/day. Each feeding session lasted an average of 5.90 ± 1.55 minutes, resulting in a feed intake rate of 77.98 ± 22.53 g/min. Mean daily feed intake was 4.76 ± 1.36 kg, and body weight increased consistently, reaching an average of 412 ± 43.44 kg, with an average daily gain (ADG) of 1.26 ± 0.38 kg. Pearson correlation analysis revealed a strong relationship between daily feed intake and visit duration (r² = 0.621; p < 0.01) and an inverse correlation between daily feed intake and feed intake duration (r² = −0.445; p < 0.05), indicating behavioral adaptation. These findings highlight the importance of monitoring feeding behavior traits concerning growth performance, enhancing our understanding of individual animal behavior and its implications for productivity while emphasizing the role of advanced technologies in optimizing feed utilization in confined livestock systems.

Effective logistics are crucial for achieving several SDGs so that improvements in Logistics Performance Index (LPI) often align with progress in SDG scores. For ASEAN countries, they may fall short of achieving 90% of their targeted SDGs and struggle to challenges of LPI fluctuations. By calculating the correlation between LPI and SDG scores in R software, this study seeks to explore the relationship between logistics performance and progress toward the SDGs in ASEAN countries from 64 secondary observations. As a result, the increasing logistics performance can greatly impact on the population well-being, accessibility, new energy approach, infrastructure formation, and sustainable production and consumption (G1, G3, G7, G9, G12) in ASEAN countries. The study contributes a background for national policymakers in the region to develop the sustainable logistics.
