This study introduces a novel instructional activity conducted in an information design class, where students creatively constructed lamp shades embedded with simple electrical circuits. The lesson began with foundational concepts in electrical systems, including the principles of direct current (DC) and alternating current (AC). Students then progressed to assembling blinking circuits and investigating energy conversion mechanisms using model motors. The curriculum advanced to practical applications such as DC-to-AC conversion, deepening their understanding of electrical engineering principles. As a culminating challenge, students attempted to illuminate a 100V incandescent bulb using batteries, prompting inquiry into voltage, current, and energy efficiency. Throughout the course, emphasis was placed on hands-on experimentation, interdisciplinary thinking, and design-based problem solving. To assess students' psychological engagement and adaptation to this learning environment, a school adaptation scale was administered. The results provided insights into students' emotional and cognitive responses to the project-based approach, underscoring the potential of integrated STEM education to enhance motivation and school satisfaction. These findings suggest that incorporating creative electrical design into information education can promote both technical proficiency and positive psychological outcomes.

Medial opening wedge high tibial osteotomy (MOWHTO) is an effective surgical procedure for joint preservation in active patients with medial knee osteoarthritis (KOA). However, older patients and those with prolonged preoperative sports cessation often struggle to resume high-impact activities, such as running, after MOWHTO. Remote rehabilitation tools may help overcome these challenges. We report the case of an older woman with prolonged cessation of sports activity who resumed sports activity after MOWHTO with the help of the mymobility® smartphone application. A 71-year-old woman with Kellgren-Lawrence grade 3 medial KOA and -5° varus alignment underwent MOWHTO. She discontinued daily 7 km runs for two years owing to knee pain. The preoperative Knee Injury and Osteoarthritis Outcome Score (KOOS) scores were 53 for Symptoms, 50 for Pain, 61 for Activities of Daily Living, 25 for Sport and Recreation Function, and 6.25 for Quality of Life, and the Oxford Knee Score (OKS) was 31. Bone union was achieved on postoperative day (POD) 90. However, she maintained a low step count (approximately 2000 steps/day) and was unable to run owing to anxiety. We used mymobility® to provide chat-based guidance, step-count goals, and video assessments of jogging and running form. Activity progressively increased, and she achieved jogging ability on POD 150 and pain-free running ability on POD 180. Her Visual Analog Scale score improved to 0 mm, KOOS and OKS scores improved substantially, and step count increased to approximately 8000 steps/day. This case indicates that mymobility® can facilitate safe and timely return to sports after MOWHTO by improving motivation, providing remote supervision, and enabling individualized activity progression. mymobility® may be particularly effective for older patients or those who cannot access specialized postoperative rehabilitation services.

This study analyzes the effectiveness of collaborative governance implemented by UPT DP3AP2KB in partnership with health services and village governments to accelerate stunting reduction in Sape District, Bima Regency. Using a descriptive qualitative case study, data were obtained through interviews, observation, and document analysis with village officials, UPT staff, health workers, and posyandu cadres. The findings indicate that cross-sector collaboration operates through institutional arrangements such as the Stunting Reduction Acceleration Team and village forums, supported by facilitative leadership in aligning stakeholder interests. Collaborative processes rely on communication, trust, shared commitment, and common goals. The collaboration has improved targeted interventions, particularly maternal and child nutrition programs, although challenges persist, including limited nutritional literacy, inadequate technical personnel, and weak intersectoral data integration. The study recommends strengthening village capacity, improving data coordination mechanisms, and expanding collaborative networks to ensure sustainable and effective governance.

BackgroundShift workers experience regular changes in their waking hours due to fluctuating work schedules. The timing of their medication intake differs depending on whether they are working a day or night shift. Sodium–glucose co-transporter 2 (SGLT2) inhibitors are prescribed once a day and are often taken before or after breakfast. However, studies on the optimal dosing times for the effective treatment of shift workers are lacking. In this study, we investigated whether the effects were different by the pattern of SGLT2 inhibitor intake for shift workers with diabetes.MethodsSeven shift workers with diabetes who were taking an SGLT2 inhibitor were analyzed. All participants took the medication upon waking for 14 days, followed by administration at a fixed time for another 14 days. Glucose levels were measured over 14 days when the drug was administered either upon waking or at a fixed time of day. The time in range (TIR), which indicates the percentage of time during which the glucose level is within the range of 70–180 mg/dL, was used as the main evaluation index.ResultsThe mean HbA1c of the participants was 7.1%. The TIR was 88.5% in the administration upon waking group and 84.9% in the administration at a fixed time group. No significant difference in TIR values was observed between the two administration groups.ConclusionA TIR of 70% or higher is recommended to prevent the onset of diabetic complications. Consistent intake of SGLT2 inhibitors, regardless of whether it is during the day or night shift, may help stabilize blood glucose levels in shift workers throughout the day and night, thereby preventing the development of complications.

Ultra-thin GaAs photovoltaics with light management offer flexible form factors, higher specific power, a route to low material cost, and inherent resilience to damaging radiation environments in space, compared to conventional on-wafer architectures with thick absorbers. Here we demonstrated an adhesive-free method of bonding ultra-thin GaAs solar cells to borosilicate glass by anodic bonding. This off-wafer processing method replaces the III-V growth substrate with a glass superstrate offering higher specific power in addition to space radiation protection. In the glass-as-superstrate embodiment, the maximum power density (Pmax) remaining factor achieves 0.86 after 1 MeV electron exposure with a fluence of 3 . 6 × 1 0 16 cm −2 , equivalent to > 15 years in a geostationary orbit (GEO), exceeding that of current commercial triple-junction space solar cells. The short-circuit current density (Jsc) of the ultra-thin GaAs solar cells with only 80 nm thick absorbers could be boosted to 17.69 mA/cm 2 using higher bandgap III-V alloys as contact and bonding layers, with further improvement of integrating advanced light management approaches for higher power conversion efficiency. • Ultra-thin GaAs solar cells are anodically bonded directly to borosilicate glass. • Offering mass reduction and radiation resilience for space applications. • The max power density remaining factor exceeds that of commercial space solar cells. • For extended space missions in hostile radiation environments.

Introduction The effects of the continued use of online health promotion activities enabled by evolving information and communication technology remain unknown. This study aimed to determine the effects of online group health promotion activities among community-dwelling older adults. Methods Twenty-four community-dwelling older adults participated in online health promotion activities for 5 wk, which included group exercises and health lectures. Physical function and activity were measured before and after the online activities. Results Two participants dropped out due to falls or by personal choice. A significant improvement in grip strength and physical activity (respectively, p < 0.01) and a partial improvement in psychological negative mood (p < 0.05) were observed after the online activity. Conclusions Online group health promotion activities enhanced participants’ psychological well-being while encouraging behavioral changes and improving physical activity levels. Our results highlight new opportunities for health promotion initiatives, particularly during times when face-to-face activities are difficult.

Introduction: Although exercise can prevent cognitive decline due to aging, few elderly individuals are able to exercise for long. Therefore, an exercise method for older adults that is feasible for a long duration without overexertion is necessary. In this study, we focused on exercise by shaking. This study examined the possibility to prevent the decline in memory through regular and long-term shaking exercise using a senescence-accelerated mouse (SAM) model. Behavioral analysis was conducted, and histological changes in the mouse brain were examined to evaluate whether this stimulation method could become a novel exercise method. Materials and Methods: The shaking exercise was applied to SAMP10 mice for 30 min 3 times per week for 25 continuous weeks. Behavioral analysis included a step-through passive avoidance test, whereas the histological analysis involved immunohistochemical staining using the anti-glutamate receptor (α-amino-3-hydroxy-5-methyl-4-isoxazole-propionate receptors [AMPAR]) antibody in the hippocampus. The number and area of nerve cells in the hippocampal regions were measured and compared between groups. Results: Behavioral analysis revealed that the shaking group retained memory longer than the control group, and memory capacity decline was suppressed. Additionally, histological examination showed that the shaking group had a higher number of AMPAR receptor-positive neurons per area in the hippocampal CA1 and CA3 regions than the control group, suggesting that degeneration and shedding of neurons due to aging was suppressed. Discussion/Conclusion: We believe that shaking could become an exercise therapy that can reduce the decline in memory with aging and expect its human application in the future.

This study aimed to explore patients’ preparedness for emergency hemodialysis in the event of a natural disaster and to determine the factors affecting such preparedness.A cross-sectional study was conducted in undergoing hemodialysis at dialysis facilities in Sapporo, Hokkaido. The participants were a cohort of 256 outpatients aged 20 years or older, 186 (72.7%) were male, and the average age was 61.9 ± 10.9 years. The participants were divided into those who had prepared for emergency dialysis treatment and those who had not. Cross tabulations were performed on the 2 groups using the following participant attributes: preparedness for dialysis during a disaster, knowledge of how to protect themselves during a disaster, and intention to dialyze and evacuate during a disaster, followed by binomial logistic regression analysis.Of the 256 study patients, 184 (71.9%) were not prepared for dialysis treatment. In logistic regression models, patients who were not prepared for dialysis treatment were found to have higher odds of being employed (odds ratio (OR): 2.469; 95% confidence interval (CI): 1.205-5.058), not being aware of disaster information acquisition methods in the event of a disaster (OR: 4.580, 95%; CI: 2.048-10.241), did not receive explanations on proper disaster response from dialysis facility staff (OR: 2.557, 95%; CI: 1.319-4.954), and believing that their family away from home would not be concerned about them (OR: 2.021; 95% CI: 1.062-3.847).Disaster preparedness in patients undergoing dialysis remain inadequate. Dialysis facilities need to strengthen their explanations of disaster response, particularly with regard to working, middle-aged people.
