Broadening Access-to Creative Experience with MR 3D Painting Reviewed

Access to arts experiences varies by income and locality, creating an experience divide. We present a low-barrier mixed-reality (MR) 3D-painting system on Meta Quest 3 that renders strokes in the user's surrounding space in passthrough MR. We conducted two complementary studies: an in-the-wild festival study with local children (MR 3D free creation) and a controlled study with university students enabling within-participant comparisons across free 2D drawing, free 3D drawing (with depth), and prompted 3D drawing. After each condition, participants rated immersion, accomplishment, perceived creativity, self-efficacy, intention to continue, and usability (plus two free-creation items) on 5-point Likert scales, and collaboration was assessed in paired tasks. We report condition-wise medians and within-participant median differences. Results suggest that MR can deliver meaningful creative experiences with minimal setup in everyday spaces and inform how task framing supports depth-oriented 3D creation.

Sericin is an underutilized biomass of hydrophilic protein removal during the refining process of silk yarn. Processing abundant functional groups such as hydroxyl, carboxyl, amide, and amino groups, sericin exhibits affinity for metal ions, making it a promising biosorbent. This study investigated the adsorption behavior of metal ions using sericin and glutaraldehyde-crosslinked sericin(Glu-sericin). Glu-sericin selectively adsorbed precious metals over Cu(II) in 0.01 M HCl. In contrast, sericin showed a red color change after Au(III) adsorption from 0.01 M and 0.1 M HCl, indicating the reduction of Au(III) to Au(0). These results show that sericin non-crosslinked treatment, both adsorption and reduction functions, making it a unique biomass material for gold recovery.

Strength training is essential for maintaining health and building an attractive physique, yet many people struggle to stick with it. One reason for this is that they fail to feel the effects of strength training. To maximize the effects of strength training, mastering proper form is essential. Therefore, I embarked on this research to reduce the number of people who quit strength training by visualizing muscle load in real time during workouts.We are developing a system that uses machine learning to visualize muscle load from user form, enabling muscle load visualization without requiring electromyography. At present, it is possible to estimate muscle load, but the accuracy of this estimation is low. Therefore, we are currently experimenting to improve the accuracy of muscle load estimation.

Unsupervised Defect Detection for Automatic Shiitake Sorting Reviewed

Automated shiitake sorting faces severe data imbalance (1,731 good vs. 241 defective images) and annotation difficulties. We compared data augmentation and unsupervised detection. First, augmenting scarce defective data with GANs failed; models either lost subtle defect features (e.g., discoloration) during pre-processing or overfit to augmentation patterns, proving label-less augmentation difficult. We then shifted to unsupervised anomaly detection (VAE+OC-SVM) trained only on good data. This model achieved perfect Recall (100%) for the defective class, identifying all bad items without a single miss. This Recall 100% capability demonstrates its high practical utility as a primary screening tool for quality control, particularly where preventing defective product leakage is prioritized (albeit with low precision). This approach highlights a path for automated sorting in data-scarce agricultural settings and suggests high transferability to other products (e.g., tomato, potato) with similar data constraints.

Adsorption Equilibrium of Selenium Oxyanions Using FeY Mixed Oxides Reviewed

Selenium oxyanions (Se(IV) and Se(VI)) in wastewater are of concern as serious pollutants due to their easy bioaccumulation and toxicity to living organisms. In this study, mixed oxides with various Y/Fe molar composition ratios (x=0.5, 1, 2) were investigated in the adsorption properties of selenium oxyanions, and were studied their adsorption mechanism. The experimental data best fits the Langmuir adsorption model, which is characteristic of monolayer adsorption (r2 >0.991). The maximum adsorption capacity (qmax) of Se(IV) and Se(VI) increased in the order of FeY2 > FeY1 > FeY0.5 and of Fe2 > FeY1, respectively. It was suggested that FeY2 adsorbed Se(IV) by formation of inner-sphere complexes and outer-sphere complexes, and adsorbed Se(VI) by outer-sphere complexes.
