Soil particle size distribution is a crucial factor in determining soil properties and classifying soil types. Traditional methods, such as hydrometer tests, have limitations in terms of time required, labor, and operator dependency. In this paper, we propose a novel approach to quantify soil particle size analysis using machine vision analysis with an RGB camera. The method aims to overcome the limitations of traditional techniques by providing an efficient and automated analysis of fine-grained soils. It utilizes a digital camera to capture the settling properties of soil particles, eliminating the need for a hydrometer. Experimental results demonstrate the effectiveness of the machine vision-based approach in accurately determining soil particle size distribution. The comparison between the proposed method and traditional hydrometer tests reveals strong agreement, with an average deviation of only 2.3% in particle size measurements. This validates the reliability and accuracy of the machine vision-based approach. The proposed machine vision-based analysis offers a promising alternative to traditional techniques for assessing soil particle size distribution. The experimental results highlight its potential to revolutionize soil particle size analysis, providing precise, efficient, and cost-effective analysis for fine-grained soils.

Cordyceps militaris is a commonly used medicinal mushroom containing various therapeutic effects such as anti-inflammatory, anti-allergic, and anti-cancer activities. This study examined whether Cordyceps militaris on germinated soybeans (GSC) has a suppressive effect on a v-ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS)-driven colorectal cancer which is notorious for its un-druggable features and the ineffectiveness of conventional therapies against it. GSC extract was prepared and its proximate composition and amino acids were analyzed. The suppressive effects were investigated with the KRAS-driven colorectal cancer cell-line, SW480. SW480 proliferation, clonogenic potential, apoptosis, and the RAS/extracellular signal-regulated kinase (ERK) pathway under the GSC treatment were analyzed by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay, flow cytometry, and Western blot, respectively. An in vivo experiment with the SW480 xenograft mouse model was performed. As a result, GSC suppressed cell proliferation by inducing the apoptosis of KRAS-driven colorectal cancer cells and inhibited clonogenic capabilities. The decrease of KRAS and ERK phosphorylation was detected by Western blot. Tumor growth was significantly suppressed when GSC was introduced to the tumor-xenograft mouse model. In conclusion, GSC suppressed KRAS-driven colorectal cancer growth both in vitro and in vivo, and can be used as an alternative or simultaneous approach in colorectal cancer therapy.
