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.

The demand for secondary batteries is increasing rapidly with the popularization of electric vehicles and the expansion of wireless electronic devices. However, the most widely used lithium-ion batteries are subject to frequent fire incidents, limiting market growth. To avoid flammability, solid electrolyte-based systems are gaining attention for next-generation lithium-ion batteries. However, challenges such as limitations in ionic conductivity and high manufacturing costs require further research and development. In this study, we aim to identify a new nitrogen-based solid electrolyte material that has not yet been widely explored. We propose a methodology for selecting the final material through high-throughput screening (HTS), detailing the methods used for material selection and performance evaluation. In addition, we present ab initio molecular dynamics (AIMD) calculations and results for nitrogen-substituted materials with carbon and oxygen replacements, including Arrhenius plots, activation energy, and the predicted conductivity at 300K for the material with the highest Li-ion conductivity. While the performance does not yet surpass the ionic conductivity and activity of conventional solid-state electrolytes, our results provide a systematic framework for exploring and screening new solid electrolyte materials. This methodology can also be applied to the exploration of different battery materials and is expected to contribute significantly to the innovation of next-generation energy storage technologies.

The purpose of this study is to examine the psychological impact of stroke, particularly post-stroke depression, anxiety, and cognitive impairment, while emphasizing the need for early intervention and personalized care to improve long-term outcomes for survivors. It explores the prevalence of these conditions, which are often underrecognized, and the varying effectiveness of intervention strategies such as pharmacological treatments, psychotherapy, and multidisciplinary rehabilitation. The findings reveal that neurological damage significantly affects mental health, complicating recovery, but highlight that early, individualized care plans tailored to patient needs can improve outcomes. The review underscores the importance of integrating mental health support into stroke rehabilitation to enhance recovery and calls for future research to address gaps in mental health care within these frameworks, advocating for a holistic, multidisciplinary approach to better support stroke survivors and their families.

This study aims to prepare reference data that can be used to improve the size suitability of elderly men’s casual wear. The sizes of men aged 65–84 from the 8th Size Korea were analyzed and compared with those aged 45–54. First, as a result of classifying their body types according to Syzing systems for male adult’s garments (KS K 0050), more than 50% of the drop body types were “a protruding belly type (BB),” and more than 95% of the lower body types were “a thick waist type (B).” Additionally, elderly men with type BB or B were 3–5cm shorter in height, waist height, chest circumference, and hip circumference than middle-aged men. As there are currently only a few brands for elderly men, this means that the following problems may arise: If an elderly man wears a middle-aged man’s top based on his chest size, the chest and hip circumferences are adequate, but the length is insufficient, the waist circumference is insufficient, and the shoulder width is considered to be excessive. Similarly, pants designed to fit a waist size designation for middle-aged individuals will be larger than intended in terms of length, hip circumference, and thigh circumference.

Moringa oleifera, a versatile plant, has been traditionally used to treat various ailments and is gaining scientific attention due to its potential as a medicine. Native to the Indian subcontinent, it is widely grown in tropical and subtropical regions, thriving in Asia, Africa, and South America, especially in arid climates. This study explores the antioxidant potential of Moringa oleifera leaf extract (MOLE), employing a comprehensive screening approach with various solvents to identify the most effective extraction method. Initial experiments assessed antioxidant efficacy and yield using distilled water (D.W.), 95% ethanol, and 95% methanol. Among these, 95% ethanol extract demonstrated superior antioxidant activity, confirmed through assays such as 2,2-diphenyl-1-14 picrylhydrazyl (DPPH) radical scavenging assay, total polyphenol content analysis, and reducing power assay. In addition, with the 95% ethanol MOLE, a higher extraction efficiency was yielded compared to other solvents, making it the most effective for large-scale preparation. HPLC analysis revealed the presence of key bioactive compounds, including ellagic acid, rutin, Q-3-O, quercetin, and kaempferol. Results revealed that MOLE, prepared using 95% ethanol, exhibited remarkable antioxidant properties, attributed to its rich polyphenolic content. This research underscores the therapeutic potential of MOLE as a natural antioxidant source and highlights the importance of solvent optimization in phytochemical extractions.

In this study, an simultaneous LC-MS/MS multi-residue analytical method was developed and validated for the residues of six neonicotinoid insecticides (acetamiprid, clothianidin, dinotefuran, imidacloprid, thiacloprid, and thiamethoxam) in honey. Sample preparation included a combination of QuEChERS extraction kit and liquid-liquid extraction method to effectively extract pesticide components from the honey matrix and optimized analytical conditions to achieve high sensitivity and selectivity. The limits of detection (LOD) and the limits of quantitation (LOQ) were set in the range of 6-15 ng/mL and 19-44 ng/mL, respectively and the correlation coefficient (R²) was greater than 0.99, confirming good linearity. In addition, the intra-day recoveries for each pesticide were 75-104%, and the coefficient of variation (CV) was less than 20%, which met the guideline recommended by the Ministry of Food and Drug Safety. The LC-MS/MS method developed in this study is expected to be used as a multi-residue analysis method for 6 neonicotinoid pesticides in honey.

Clove (Syzygium aromaticum) is a highly valued medicinal plant native to Aisa. Widely used as a spice, renowned for its medicinal properties, particularly in Ayurveda and traditional Chinese medicine. In this study, clove bud extract (CBE) was prepared at different ethanol concentrations of 50%, 80%, and 90%, respectively. The antioxidant activity of the CBE was evaluated through DPPH, polyphenol, and reducing power assays, revealing its strong antioxidant potential, with 90% ethanol being the most effective extract. HPLC analysis identified eugenol (8.7 mg/g) as the major active compound, known to possess anti-inflammatory and antioxidant properties. Given the role of oxidative stress and inflammation in atopic dermatitis (AD), the therapeutic potential of CBE was explored using a 1-chloro-2, 4-dinitrobenzene (DNCB)-induced AD mouse model. Five-week-old BALB/c mice were induced with AD by topical application of DNCB. CBE was administered topically to the affected skin (back and ear) areas for 4 weeks. The treatment of CBE significantly reduced the severity of clinical dermatitis, decreased epidermal thickness, and lowered mast cell and eosinophil infiltration in skin tissue, as observed through hematoxylin eosin staining and toluidine blue staining. The results demonstrated CBE as a promising therapeutic agent for managing AD through its regulation of skin inflammation and oxidative stress, making it a potential candidate for future treatments of inflammatory skin disorders.

Background: Cisplatin, a chemotherapeutic agent often causes nephrotoxic side effects. Lipopolysaccharide (LPS) is known to induce pro-inflammatory responses, often leading to septic renal injury. We hypothesized that the combination of cisplatin and LPS would amplify renal injury, thereby improving a renal injury model. Therefore, we administered both agents to mice and evaluated renal injury indicators. Methods: Eight-week-old male C57BL/6 mice were injected with cisplatin (8, 10, or 12 mg/kg) and LPS (5 mg/kg) on days 1 and 4 following of each week. Mice were euthanized at specific time points to assess renal injury. Body weight, renal weight, area, and BUN levels were measured to evaluate renal damage. Additionally, hematoxylin and eosin (H&E) and Masson’s trichrome (MT) staining were performed to assess histological changes. Results: The combination of cisplatin and LPS significantly reduced body and renal weight compared to cisplatin alone. A high dose of cisplatin (12 mg/kg) resulted in a 50% mortality, while, lower doses (8 and 10 mg/kg) showed 100% survival. Significant renal injury was observed in the 10 mg/kg cisplatin group administered for two weeks. In the 8 mg/kg cisplatin group, no changes were observed after two weeks, but renal damage appeared after four weeks. Histological evaluations in the 10 mg/kg cisplatin group administered for two weeks showed renal injury features, including tubular damage and fibrosis. Conclusions: Administering cisplatin (10 mg/kg) with LPS for two weeks or cisplatin (8 mg/kg) with LPS for four weeks resulted in a distinct renal injury, effectively establishing a renal injury mouse model.

Following the previous study, which investigated the pharmacological properties of the Technekitty injection (Tc-99m), the toxicity of a single intravenous administration of the Technekitty injection (Tc-99m) and the side effects that may occur at the diagnostic dose were confirmed. The Technekitty injection (Tc-99m) was administered intravenously once at a dose of 0, 0.67, 2.0, and 6.0 mCi/kg to 5 male and female rats per group. Mortality, general symptom observation, and weight measurement were performed for 2 weeks, followed by observation of autopsy findings. There were no deaths, and no statistically significant weight change was observed. No abnormal systemic signs related to the Technekitty injection (Tc-99m) were observed. These results confirmed that Technekitty injection (Tc-99m) can be safely administered intravenously at doses up to 6.0 mCi/kg. Additionally, technetium-99m at an average dose of 2 mCi (74 MBq) has been verified as a diagnostic dose without adverse effects, allowing the Technekitty injection (Tc-99m) to be used safely without side effects at this dosage. This study demonstrates that the Technekitty injection (Tc-99m) has a wide safety margin, supporting its potential for clinical application. Moreover, these findings align with the nonclinical safety standards for radiopharmaceuticals, reinforcing its utility in veterinary medicine. The Technekitty injection (Tc-99m) is expected to be applicable for clinical diagnosis as a veterinary drug in Korea.

Thyroid scanning using technetium-99m (99mTc) is the gold standard for diagnosing feline hyperthyroidism. In cats with an overactive thyroid, a thyroid scan is the most appropriate imaging technique to detect and localize any hyperfunctional adenomatous thyroid tissue. In this study, the pharmacological properties of the Technekitty injection (Tc-99m), developed as a diagnostic agent for feline hyperthyroidism using 99mTc as an active ingredient, were tested in FRTL-5 thyroid follicular cell line and ICR mice. The percentage of cell uptake of the Tc-99m in FRTL-5 thyroid cells was 0.182 ± 0.018%, which was about 6 times higher compared to Clone 9 hepatocytes. This uptake decreased by 38.2% due to competitive inhibition by iodine (sodium iodide). In tissue distribution tests by using ICR mice, the highest distribution was observed in the liver, kidneys, spleen, lungs, and femur at 0.083 hours after administration, and this distribution decreased as the compound was excreted through the kidneys, the primary excretory organ. Maximum distribution was confirmed at 1 hour in the small intestine, 6 hours in the large intestine, and 2 hours in the thyroid gland. Additionally, the total amount excreted through urine and feces over 48 hours (2 days) was 78.80% of the injected dose, with 37.70% (47.84% of the total excretion) excreted through urine and 41.10% (52.16% of the total excretion) through feces. In conclusion, the Tc-99m has the same mechanism of action, potency, absorption, distribution, metabolism, and excretion characteristics as 99mTc used for feline hyperthyroidism in the United States, Europe, and other countries, because the Technekitty injection (Tc-99m) contains 99mTc as its sole active ingredient. Based on these results, the Technekitty injection (Tc-99m) is expected to be safely used in the clinical diagnosis of feline hyperthyroidism.

Afghanistan is a producer of high-quality pistachios among the top ten producers in the World. Nowadays, these edible nuts are losing their quality and quantity due to hemipteran insect infestation and their diversity during all growth phases in the country borderline. The expansion of the pistachio pest in Iran has caused concerns for Afghanistan, especially in the provinces of Herat, Badghis, and Takhar which are close to the Iran borders. Hence, this survey was initiated to primarily detect the phytophagous insect pest presence in the pistachio open forest areas and to know what management tools were effectively used in alleviation of the pest infestation. Our findings indicated that galling aphids, aphids, thrips, and root beetles received the maximum positive responses in the Herat province, but psyllids, aphids, root beetles, leave miners, fruit borers and thrips received the highest responses in Badghis province. In addition, Takhar province depicted plant bugs, twig borer moths, galling aphids, leaf miners, and leafhoppers got the most positive responses accordingly. In the meantime, the data showed that management outcomes were not satisfactory despite the use of sanitation, cultural practices, and chemical application. The survey presented significant differences in the prevalence of pest and in the application of pest control methods among the survey regions. Finally, it is essential to develop the strategy of integrated pest management in order to stop the phytophagous insects from turning into actual pests. This will reduce the pistachio loss annually and improve the nut culture quality in Afghanistan.

Despite the widespread recognition of the prominent contribution of key language subskills, such as grammar and vocabulary knowledge, to reading comprehension, a research consensus on their relative significance has not been reached. Moreover, the extent of the contribution vocabulary depth makes to reading comprehension has received little research attention. The present study assessed the relative potential contribution of vocabulary depth and grammar knowledge to advanced Korean EFL college students’ reading comprehension abilities, while controlling for their language proficiency and vocabulary breadth, through hierarchical regression analyses. 56 advanced EFL Korean college students were tested on reading comprehension abilities and a range of reading-related subskills including vocabulary breadth, vocabulary depth, grammar, and listening comprehension in English. The findings revealed the unique contribution of vocabulary depth to reading comprehension abilities beyond the effects of both vocabulary breadth and grammar knowledge when English proficiency was controlled for. The findings further underscore the need for balanced approaches in developing L2 learners’ language skills to enhance their reading comprehension abilities.

This study investigates how adding cognitive stimulation to exercise impacts overall outcomes. Cognitive stimulation involves engaging mental processes like attention, memory, and problem-solving while being physically active. The intervention integrates activities that challenge mental functions into exercise routines. Existing research suggests that such interventions can improve various aspects of exercise performance, such as adherence, enjoyment, and perceived effort. Additionally, they may also lead to enhanced cognitive function and mental well-being, hinting at potential combined benefits of mental and physical activity. Understanding the effects of cognitive stimulation on exercise can help in developing more effective strategies for promoting both physical and cognitive health. In summary, physical exercise emerges as a powerful tool for enhancing cognitive stimulation and mental well-being. By making regular physical activity a habit, individuals can reap cognitive benefits alongside physical ones, underlining the importance of including exercise in daily routines for optimal cognitive function and overall health.
