Empowering flood preparedness: Enhancing flood knowledge, risk perception, and preparedness among primary school learners in flood-affected southern Thailand
No full textThe increasing frequency and severity of floods owing to climate change particularly affect children, making enhanced preparedness strategies essential for mitigating their impact. This study aimed to evaluate the effect of local topography maps on flood knowledge, flood risk perception (FRP), and flood preparedness (FP) among elementary school students aged 11–12 in Nakhon Si Thammarat Province, Thailand. A quasi-experimental design was employed, with 150 students divided into an experimental group (n = 75) and a control group (n = 75). The intervention comprised a flood education programme incorporating discussions, workshops, slide presentations, and interactive teaching methods to enhance students' knowledge, FRP, and FP. Data were collected via questionnaires at three-time points: pre-test (T0), post-test (T1), and follow-up (T2) between August and October 2023. Statistical analyses included t-tests, Wilcoxon rank-sum tests, ANOVA, and the Friedman test. The results indicated that the flood education programme significantly improved students' preparedness, though no significant differences in flood risk perception were observed between groups. The intervention highlighted the need to enhance students' understanding of local topography and flood hazard mapping. This study suggests integrating localized flood information into preparedness programs to improve knowledge, risk perception, and preparedness in classroom disaster education.Funding
The Royal Thai Government generously supported this study through a graduate scholarship awarded to the first author.journal articl
Hydrogen gas inhalation ameliorates glomerular enlargement after hypoxic-ischemic insult in asphyxiated piglet model
Get PDF香川大学Kagawa University博士（医学）Acute kidney injury (AKI) has been reported to occur in 30-70% of asphyxiated neonates. Hydrogen (H2) gas became a major research focus in neonatal medicine after the identification of its robust antioxidative properties. However, the ability of H2 gas to ameliorate AKI is unknown. We examined histopathological injuries in the piglet renal cortex on day 5 after a hypoxic-ischemic (HI) insult and if H2 gas can alleviate kidney injuries. Twenty piglets were divided into three groups: no insult (Control, n = 6), HI insult alone (HI, n = 8), and HI insult with H2 gas ventilation (HI-H2, 2.1-2.7% for 24 h, n = 6). The total glomerular cell count was significantly higher in the HI group than in the other groups, with no difference between the HI-H2 and control groups. Proximal tubular lumen narrowing was significantly increased in the HI group versus control, but not in the HI-H2 group. In this piglet model, glomerular enlargement with an increase in glomerular cell number due to tubular lumen narrowing was observed on day 5 after HI insult. H2 gas effectively suppressed this glomerular cell increase and tubular lumen narrowing.departmental bulletin pape
De-escalation of Monitoring in Active Surveillance for Prostate Cancer: Results from the GAP3 Consortium
No full textBackground and objective
There is no consensus on de-escalation of monitoring during active surveillance (AS) for prostate cancer (PCa). Our objective was to determine clinical criteria that can be used in decisions to reduce the intensity of AS monitoring.Methods
The global prospective AS cohort from the Global Action Plan prostate cancer AS consortium was retrospectively analyzed. The 24 656 patients with complete outcome data were considered. The primary goal was to develop a model identifying a subgroup with a high ratio of other-cause mortality (OCM) to PCa-specific mortality (PCSM). Nonparametric competing-risks models were used to estimate cause-specific mortality. We hypothesized that the subgroup with the highest OCM/PCSM ratio would be good candidates for de-escalation of AS monitoring.Key findings and limitations
Cumulative mortality at 15 yr, accounting for censoring, was 1.3% for PCSM, 11.5% for OCM, and 18.7% for death from unknown causes. We identified body mass index (BMI) >25 kg/m2 and <11% positive cores at initial biopsy as an optimal set of criteria for discriminating OCM from PCSM. The 15-yr OCM/PCSM ratio was 34.2 times higher for patients meeting these criteria than for those not meeting the criteria. According to these criteria, 37% of the cohort would be eligible for de-escalation of monitoring. Limitations include the retrospective nature of the study and the lack of external validation.Conclusions
Our study identified BMI >25 kg/m2 and <11% positive cores at initial biopsy as clinical criteria for de-escalation of AS monitoring in PCa.Patient summary
We investigated factors that could help in deciding on when to reduce the intensity of monitoring for patients on active surveillance for prostate cancer. We found that patients with higher BMI (body mass index) and lower prostate cancer volume may be good candidates for less intensive monitoring. This model could help doctors and patients in making decisions on active surveillance for prostate cancer.journal articl
Research collaboration between Faculty of Engineering and Design of Kagawa University and National Chiayi University - Recent activities and future prospects: Development of High Effective, High Functional Magnetic Film Materials for SDGs Society
Get PDFUnder the international collaboration between Department of Engineering and Design of Kagawa University and Department of Electro-Engineering of National Chiayi University, we have performed the research and development of magnetic thin film materials with high performance, high efficiency and high functionality, which will be used as various sensors and electromagnetic motors. ultrathin films consisting of magnetic metals of Co, Ni, Fe and nonmagnetic materials of dielectric sapphire （Al2O3） or III-V semiconductor GaAs and GaN, have been fabricated using high-precision deposition technique of sputtering or molecular beam epitaxy ［1］. And their physical properties have been evaluated by detection of the magneto-optic Kerr effect （MOKE） using laser reflection analysis and Faraday effect using transmission measurement. From the MOKE results, we found that, in the case of the deposition under lower substrate temperature condition, the magnetic properties showed the strong angular dependence between the directions of incident laser beam and the film surface, which might be caused from the dominant crystal orientation of upper magnetic layer influenced by lower substrate crystal direction. This crystal direction effect on magnetic properties suggests the high controllability of magnetization in sensor device or power motor．departmental bulletin pape

Preliminary Investigation into Finger Action Discrimination Classifiably Using Neural Network
No full text本研究は、１チャンネルの筋電センサ（EMG）を用いて指の動作識別が可能かを検討した予備的調査である。重度重複障害者にとって、従来のマウスやキーボードの操作は困難であり、代替となる入力インタフェースの確立が求められている。そこで本研究では、中指および人差し指の動作をシミュレートしたEMG波形データを生成し、指ごとの分類モデルを構築した。初期段階ではLSTMよりもSVMが高い精度を示したが、正規化、ノイズ除去、特徴量拡張、データ拡張、およびBidirectional LSTM構造の導入により、最終的には深層学習モデルでも100%の識別精度を達成した。この結果は、最小限のセンサ構成であっても高精度な指識別が可能であることを示しており、装着負担の低減や支援技術への応用において極めて有望である。今後は、実データによる検証、リアルタイム処理への対応、識別対象の拡張を進め、現場での利用に耐えうる実用的なインタフェースの確立を目指すdepartmental bulletin pape
