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.

This study aims to examine how the marketing characteristics of Wanghong (Chinese internet influencers) influence Chinese consumer attitudes and purchase intentions toward fashion products. Specifically, it investigates how the factors of expertise, trustworthiness, and attractiveness play a critical role in shaping consumer behavior in the digital marketing landscape. The study employed a survey-based quantitative approach, collecting data from 272 Chinese consumers engaging regularly with Wanghong marketing content. A structured questionnaire using a 5-point Likert scale was developed, incorporating validated measurement items from previous studies. The collected data were then analyzed using exploratory factor analysis, correlation analysis, and multiple regression analysis. The findings indicate that while expertise negatively influences consumer attitudes, trustworthiness and attractiveness have a positive impact. Furthermore, trustworthiness and attractiveness were found to significantly enhance purchase intention, while expertise was found to have no significant effect. Additionally, the findings showed that consumer attitudes toward Wanghong-mediated marketing play a mediating role in the relationship between Wanghong characteristics and purchase intention, with the results suggesting that consumers perceive highly knowledgeable Wanghong as distant or overly commercial, reducing their willingness to engage. In contrast, Wanghong who exhibit trustworthiness and personal appeal are more effective in driving consumer interest and purchases. These findings provide valuable insights for fashion brands aiming to optimize influencer marketing strategies in China, emphasizing the importance of relationship-driven and authenticity-focused marketing.

Women in their 50s undergo significant changes to their bodies, including weight gain and rapid increases in body mass index (BMI) due to menopause. This study aimed to develop a basic bodice pattern suitable for women with a “square” body type, which is the most common type among Korean women in their 50s. We used a body shape avatar representative of square-body-type women in their 50s, provided by 6th Size Korea (KATS, 2010) as the model. This avatar was loaded into a virtual fitting program to evaluate the fit of the research pattern. The results of the study were as follows. Using the 3D virtual fitting program, the ideal bodice pattern was found to be close-fitting, based on an analysis of the body surface of women in their 50s with a square body type. This population’s characteristic body features included a rounded back, forward-protruding waist, forward-tilted neck, and shoulder tips angled toward the center-front. Because of the protruding abdomen, the bodice’s waist dart value was lower than average. The base bodice design for this body type was adapted from the research pattern of Jun and Jang (2024). Adjustments for this study included adding 0.5 cm to the center-back length and designing the profile line from the back neckline to the armpit wall. Further, the front bodice waist dart was omitted to accommodate the protruding abdomen. After two rounds of revisions, evaluations of the virtual fitting significantly improved, with scores increasing from 2.38 out of 5 to 4.82 out of 5.

Being in a stable continental region (SCR) with a limited history of instrumentation, South Korea has not collected sufficient instrumental data for data-driven ground motion models. To address this limitation, we investigated the suitability of the hybrid ground motion simulation method that Graves and Pitarka (2010, 2015) proposed for simulating earthquake ground motions in South Korea. The hybrid ground motion simulation method used in this study relies on region-specific parameters to accurately model phenomena associated with the seismic source and the wave propagation. We initially employed relevant models and parameters available in the literature as a practical approach. We incorporated a three-dimensional velocity model developed by Kim et al. (2017) and a one-dimensional velocity model presented by Kim et al. (2011) to account for the crustal velocity structure of the Korean peninsula. To represent the earthquake source, we utilized Graves and Pitarka’s rupture generator algorithm along with a magnitude-area scaling relationship developed for SCR by Leonard (2014). Additionally, we assumed the stress and attenuation parameters based on studies of regional seismicity. Using the implemented platform, we simulated the 2016 Mw5.57 Gyeongju earthquake and the 2017 Mw5.4 Pohang earthquake. Subsequently, we compared results with recorded accelerations and an empirical ground motion prediction equation at strong motion stations. Our simulations had an overall satisfactory agreement with the recorded ground motions and demonstrated the potential of broadband hybrid ground motion simulation for engineering applications in South Korea. However, limitations remain, such as the underestimation of long-period ground motions during the 2017 Pohang earthquake and the lack of a model to predict the ground motion amplification associated with the near-surface site response accurately. These limitations underscore the importance of careful validation and refinement of region-specific models and parameters for practically implementing the simulation method.

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.

배추는 한국에서 연중 소비되는 김치의 주 원료이며, 노지에서 주로 재배되고 있다. 온실 재배 수경재배 시 스템은 기후 변화에 영향을 받지 않고 토양을 대신한 배지를 사용함으로써 토양 병원균으로부터 작물을 보호할 수 있어 재배 안정성을 확보할 수 있다. 수경재배용 배지 중 일부는 재사용이 가능하고, 이러한 배지의 조성은 작물 생 장과 품질에 영향을 줄 수 있다. 본 연구는 재사용 코이어 배지 또는 인공배지를 첨가한 배지 조성에 칼슘 공급원을 처리하여 배추(Brassica rapa ‘Bulam Plus’)를 수경재배 했을 때 배액과 생육에 미치는 영향을 알아보고자 10주동 안 수행하였다. 배지 조성은 재사용 코이어: 피트모스: 펄라이트 비율(v/v/v)을 각각10:0:0, 7:2:1, 5:3:2의 세 처리 와 각 처리에 칼슘 공급원인 CaSO4(G)와 CaO(Q)를 200g/m2 혼합한 총6가지 처리(G10:0:0, G7:2:1, G5:3:2, Q10:0:0, Q7:2:1, Q5:3:2)하였다. 배액량, 배액의 pH와 EC, 생육, 잎끝마름(Tipburn)발생을 조사하였다. 배추 생육이 증가함에 따라 모든 처리에서 배액률은 감소하였고, 처리 9주째는 20% 미만으로 감소하였다. 배액의 EC는 G 처리가 Q 처리 보다 높았으나 배액의 pH는 Q 처리가 높았다. 처리 10주째 배추의 초장, 엽수, 엽폭은 처리 간 유의성이 없었다. 엽 록소함량값(SPAD)은 G7:2:1과 G5:3:2처리에서 높게 나타났다. 잎의 당도와 건물중은 Q5:3:2처리에서 높았으며, 건물 중이 관찰되었다. 배추의 잎끝마름 발생은 처리 25일째 관찰되었으며, G7:2:1처리에서 가장 높았다. 이상의 결과를 종합할 때 CaO가 첨가되고 재사용 코이어 50% 함유된 Q5:3:2처리에서 수경 재배된 배추 생육이 양호하였다. 본 연 구는 간이 시설을 적용된 수경재배 시스템에서의 안정적 배추 재배를 위해 재사용 코이어 배지와 칼슘 공급원에 관 한 기본 정보를 제공하고자 하였다.

We prepared porous poly(ε-caprolactone)/poly(lactic-co-glycolic acid) (PCL/PLGA) 3D scaffolds with surfaces that were modified through the co-precipitation of calcium phosphate (CAP) with binary drug components, including risedronate (RSD) and hyaluronic acid (HyA). The 3D porous biodegradable PCL/PLGA scaffolds were fabricated by sintering microspheres prepared with a 30/70 PCL/PLGA blend. The co-precipitation of the CAP coating with binary drug components significantly enhanced the proliferation and differentiation of rat mesenchymal stem cells (rMSCs) on the scaffolds. Although the presence of both HyA and RSD positively improved proliferation and differentiation, HyA and RSD were more effective on osteoblastic proliferation and differentiation, respectively. These results strongly demonstrate that the drug effects on osteoblastic responses were closely interconnected. The two drugs affect rMSCs behavior in a concentration-dependent manner, requiring a balance between proliferation and differentiation for optimal bone regeneration. We expect this surface modification technique could potentially be utilized for the fabrication of functionalized biodegradable scaffolds and delivery of drug mixtures.

We introduce a new clustering algorithm, MulGuisin (MGS), that can identify distinct galaxy over-densities using topological information from the galaxy distribution. This algorithm was first introduced in an LHC experiment as a Jet Finder software, which looks for particles that clump together in close proximity. The algorithm preferentially considers particles with high energies and merges them only when they are closer than a certain distance to create a jet. MGS shares some similarities with the minimum spanning tree (MST) since it provides both clustering and network-based topology information. Also, similar to the density-based spatial clustering of applications with noise (DBSCAN), MGS uses the ranking or the local density of each particle to construct clustering. In this paper, we compare the performances of clustering algorithms using controlled data and some realistic simulation data as well as the SDSS observation data, and we demonstrate that our new algorithm finds networks most correctly and defines galaxy networks in a way that most closely resembles human vision.

간의 단순 낭종은 임상에서 흔히 보는 질환으로 대부분은 증상이 없고 영상검사에서 우연히 발견되고 있다. 이 중 약 5% 정도가 크기와 위치 또는 합병증의 발생으로 증상을 호소한다고 보고되고 있다. 증상을 유발하는 간낭종은 경피적 또는 내시경초음파 유도하에 경화술을 시행하거나 수술적 치료를 하여 없애거나 크기를 줄여 증상을 호전시킬 수 있다. 낭종내의 액체만 배액하는 치료는 높은 재발률이 문제가 되어서 경화술을 병행하는데 경화제로는 에탄올, tetracycline, polidocanol 등이 사용되고 있다. 이러한 비수술적 경화술은 증상을 완화시키고 낭종의 크기를 효과적으로 줄이며 안전성이 입증되고 있다. 본 종설에서는 간낭종에 대한 2가지 새로운 접근법을 주장하고자 하는데 첫째는 간낭종이 커져서 증상이 나타나기 전에 조기에 치료하자는 것이다. 크기가 증가하고 있는 간낭종을 조기에 치료하지 않고 추적관찰만 하게 되면 증상을 유발하고 또한 합병증도 병발할 가능성이 있으며 또한 치료가 침습적인 수술적 절제가 될 가능성이 높기 때문이다. 둘째는 간낭종의 주치료 방법은 수술적 치료가 아닌 경피적 또는 내시경초음파를 이용한 비수술적 치료가 되어야 한다는 점이다. 최근에 비수술적 치료의 효과와 안전성이 대한 연구가 지속적으로 발표되고 있기 때문이다. 이러한 접근 방식의 변화로 간낭종을 더 안전하고 효과적으로 관리하고 치료할 수 있다고 생각된다.

H2O AutoML also performed well at 94.25 percent, illustrating the effectiveness of automated selection for intricate imaging tasks. Other models scored lower. Conclusion: These findings highlight the potential of AI-driven solutions for faster and more precise pet skin disease diagnoses. Future investigations should incorporate broader disease varieties, multimodal data, and clinical validations to solidify the practicality of these approaches in veterinary medicine.

Background: Squats are often used to strengthen the quadriceps femoris, but they are affected by lower extremity posture. Objectives: The study of this was to investigate the effect on the muscle activity of the vastus medialis and the vastus lateralis according to the ankle angle, during squat exercise. Design: Quasi-Experimental research. Methods: Thirty healthy adult males participated in the study and the subjects measured the vastus medialis muscle and the vastus lateralis muscle and measured the maximum electromyogram. The subjects performed one squat at ankle angles of toe out 0˚, toe out 20˚, and toe out 40˚, then rested for 2 minutes and repeated 3 sets. Data analysis was performed using the repeated measures analysis of variance and paired t-test for window program. The significance level for statistical treatment was set at .05. Results: There was a statistically significant difference in the vastus medialis and the vastus lateralis in the ankle angles of toe out 0˚, toe out 20˚, and toe out 40˚during squat (P<.05). The muscle activity of the vastus medialis and vastus lateralis showed the highest at the ankle angle toe out 20˚, and the vastus medialis showed a statistically significant increase at toe out 0˚ than at toe out 40˚ (P<.05). In vastus lateralis, toe out 40˚ increased statistically more than toe out 0˚(P<.05). Conclusion: In the early stage of rehabilitation for patients with knee pain, strengthening the vastus medialis muscle at toe out 0˚and performing squat exercise at toe out 20˚ in the later period will be helpful. However, if you exercise at toe out 40˚ beyond toe out 20˚, the vastus lateralis muscle becomes dominant, so it will not be helpful during squat exercise.

Conclusion: This comprehensive analysis of the AI-Hub fitness dataset provides a robust foundation for developing AI models for fitness posture evaluation and feedback, benefiting exercise coach web/app service developers.

Background: For patients with neck pain, a taping method has been used to promote thoracic spine extension. To induce thoracic spine extension without back pain, a neutral lumbo-pelvic position must be established. The spiral trunk taping method can induce a neutral lumbo-pelvic position and thoracic spine extension. Objectives: To determine the effectiveness of spiral trunk taping in inducing thoracic spine extension and neutral lumbo-pelvic position in patients with neck pain. Design: A randomized controlled trial. Methods: Thirty patients with neck pain were randomly assigned to groups. The experimental group received spiral trunk taping and the control group received sham taping. The resting position visual analogue scale (VAS) and VAS during painful movement were measured and compared pre and post treatment. Results: Significant within-subjects changes were resting position VAS (F=59.823, P=0.001) and VAS during painful movement (F=76.128, P=0.001). Significant between-subject changes were resting position VAS (F=10.402, P=0.003) and VAS during painful movement (F=7.657, P=0.01). Conclusion: Spiral trunk taping, which can induce thoracic spine extension and a neutral lumbo-pelvic position, was effective for neck pain. This study demonstrates the potential of a systemic taping approach in the management of neck pain, and provides important clues for future clinical applications.

Background: When shorter muscles are restored to normal, non-specific low back pain, which is the mechanism that causes pain along with muscle relaxation, disappears. Among the stretching methods, self-stretching is a good exercise method not only for treatment but also for preventive purposes. Objectives: To find out what is the most effective method of self-stretching, which is often used in treatment and preventive arbitration, which can reduce muscle activity and increase spinal flexibility in patients with non-specific back pain. Design: Randomized controlled trials. Methods: Three self-stretching exercise methods for erector spinae are randomly assigned to 13 people each, and three self-stretching exercise methods are performed for each study subject. Surface electromyography using, was performed to measure the erector spinae muscle activity. flexibility was measured through Trunk flexion test in a standing position. Muscle activity and flexibility were measured before and after stretching. Results: The difference in muscle activity and flexibility in the three groups, including cat stretching, seated stretching, and Reclining stretching, all showed statistically significant differences. There was no statistically significant difference in comparison between the three groups of stretch muscle activity. However, a statistically significant difference was shown in the comparison of the variability between the three groups of flexibility. In a post-mortem analysis comparing the amount of change in flexibility, the flexibility of the seated stretching in the chair increased significantly compared to the cat stretching group. Conclusion: It can be confirmed that the stretching method of the erector spinae, cat stretching, seated stretching, and Reclining stretching, all have positive effects on muscle activity and flexibility.

Background: Recent cases of spinal cord infarction combined with cerebral infarction have demonstrated improved walking ability through pharmacological treatment and rehabilitation.

MFT scores increased to 18 (left) and 25 (right). BBS improved from 1 to 23 points, and the 10MWT time decreased to 19.84 seconds. K-MBI scores rose from 12 to 39 points. Conclusion: A multidisciplinary approach, including robotic therapy, significantly improved functional recovery, facilitating reintegration into daily life.

Background: The diaphragm release technique, commonly used in COPD patients, improves diaphragmatic mobility and inspiratory capacity. Diaphragmatic breathing, with slow deep breaths, supports autonomic regulation and benefits the brain, cardiovascular, and respiratory systems. However, research on their combined effects on respiratory function remains limited. Objectives: To investigate the effects of manual diaphragm release on respiratory functions, specifically focusing on forced vital capacity (FVC), forced expiratory volume in one second (FEV1), diaphragmatic mobility, and chest expansion. Design: A randomized controlled trial. Methods: The study involved 26 university students, who were randomly assigned to either the experimental group (Manual diaphragm release + Diaphragmatic breathing, MDR) or the control group (Diaphragmatic breathing, DB). Measurements taken before and after the immediate intervention included diaphragmatic mobility, chest expansion, FVC, and FEV1. Results: In the experimental group, significant differences were observed in diaphragmatic mobility, FVC, and FEV1 between the pre- and post-intervention measurements, while the control group had no significant changes. The experimental group showed significant improvements in diaphragmatic mobility and FVC compared to the control group. Conclusion: MDR significantly enhance diaphragmatic mobility and FVC in university students compared to DB. These findings suggest that MDR is an effective non-invasive intervention for improving specific respiratory functions.
