Evidence on effective teaching methods to promote gender awareness in nursing education remains limited. To compare the effectiveness of lecture-based learning (LBL), guided university debate (GUD), and problem-based learning (PBL) on gender-related competencies among undergraduate nursing students. A quasi-experimental pre-post study involved first-year nursing students across 3 academic years, each receiving LBL (2021-2022), GUD (2022-2023), or PBL (2023-2024). Outcomes included gender knowledge, sensitivity, role ideology, and pain legitimation, measured at baseline, postintervention, and 6-month follow-up using validated scales. GUD and PBL significantly improved gender knowledge compared to LBL, with effects sustained at 6months. PBL showed a short-term increase in gender sensitivity, while GUD's improvements were more pronounced over time. No significant differences were found for gender role ideology or pain legitimation. Active methodologies, particularly GUD and PBL, are more effective than LBL for enhancing gender competence in nursing education.

Open-source software (OSS) has become a mainstream technology in recent years. However, its secure application requires a thorough understanding of the various security risks involved, e.g., vulnerability and developmental risks. Whenever a new vulnerability is identified in an OSS in use, the security administrator must update it. On the other hand, if an OSS is not under active development, an alternative OSS should be considered because newly identified vulnerabilities may not be fixed. Further, besides the OSSs directly in use, their dependencies must also be csonsidered. Thus, security administrators require a specialized method to analyze vulnerability and developmental risks of OSSs, considering their dependencies. For this purpose, a method is proposed in this study that identifies security risks in an OSS by extracting, linking, and visualizing its vulnerability, developmental, and dependency information using vulnerability databases and packaging management tools. Its performance and processing time are evaluated by applying it to the visualization of an OSS with additional vulnerability information and different scores representing development information.

After the popularization of serum immunoglobulin G4 (IgG4) measurement and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in our institute, surgical resection for non-neoplastic diseases of the pancreas became less common. Although the incidence of such false-positive cases was clarified in the 10-year period after the introduction of these measures (2009-2018), these data were not compared with the 30years before 2009 (1979-2008). This study was performed to determine the percentage of autoimmune pancreatitis (AIP) that was included during the latter period and how the numbers of false-positive cases differed between the two periods. From 1979 to 2008, 51 patients had clinical suspicion of pancreatic carcinoma (false-positive disease). Among these 51 patients, 32 non-alcoholic patients who had tumor-forming chronic pancreatitis (TFCP) were clinically, histologically, and immunohistochemically compared with 11 patients who had TFCP during the latter 10-year period. Retrospective IgG4 immunostaining of false-positive TFCP revealed 14 (35.0%) cases of AIP in the former 30years versus 5 (45.5%) in the latter 10years. There were 40 (5.9%) cases of TFCP among 675 patients in the former 30years and 11 (0.9%) among 1289 patients in the latter 10years. When the TFCP ratio of pancreatic resections and the AIP ratio of false-positive TFCPs were compared between the two periods, the TFCP ratio was 5.9% versus 0.9% and the AIP ratio was 35.0% versus 45.5%, respectively. It can thus be speculated that IgG4 measurement and EUS-FNA are absolutely imperative for the diagnosis of TFCP.

使用済燃料プールへの海水の注入は，燃料集合体を支える燃料ラックとバウンダリーとしての機能を持つプールライナーの腐食のリスクを高める．アルミニウム合金製ラックとステンレス鋼製ライナーの導通により，ラックの異種金属接触腐食が懸念され，一方，ライナー側は防食される可能性がある．境界要素法解析によって，これらのマクロセル挙動を考察した．冷却水の導電率が高くかつ微生物の影響を考慮する場合，ラックに最大数mm/yの腐食増が予測されたが，導電率の低下によって腐食は大幅に低減した．ラックの健全性を維持するために，水質浄化による導電率低減および微生物対策が重要であることが定量的に明らかにされた．

We have introduced a global-local live imaging microscope (GLIM) system to record local molecular dynamics at a high magnification (local events) and whole cell events at a low magnification (global events) in parallel without exchanging objectives [1]. Figure shows the outline of the GLIM system used in this study. High-magnification DIC or spindisc confocal microscope (Yokogawa CSU-X1-M) images were acquired using optical system 2, and wide-field DIC or fluorescence images of the cell were acquired using a Nikon confocal microscope C1 (optical system 1). The global image was acquired after obtaining the local images, followed by waiting for a defined duration. This cycle was repeated until the end of cell division. Using this system, we could detect the changes in molecular/structural dynamics in the cell cortex during the division of GFP-labeled tobacco BY-2 cells and that of Tradescantina stamen hair cells at a time-resolution of one minute. This work was supported by JST SENTAN.

In Earth orbit, solar power generation is possible free from any absorption or disturbances by the Earth's atmosphere. Therefore, space solar power station is planned for the future. We discuss the assembly work of a large antenna reflector by a robot arm. For the assembly work, positioning of the arm using visual servo to colored markers is proposed. The characteristics of the new image processing method of colored marker were confirmed by testing using a ground test-bed with a positioning table. The test results are also described in this paper.

Background: Cortical microinfarcts (CMIs) are frequently detected in autopsy brains of elderly subjects, and distributed predominantly in the area of predilection for cerebral amyloid angiopathy (CAA). Recently these lesions have been detected on high-filed MRI using double inversion recovery (DIR) and 3D-fluid attenuated inversion recovery (FLAIR). Radiological diagnosis according to Boston criteria for CAA may be reinforced by detecting CMIs. Methods: We performed a prospective analysis of 36 patients diagnosed as clinically probable CAA by Boston criteria, including multiple strictly lobar microbleeds as a diagnostic indicator. These patients were recruited at the Department of Neurology, Mie University Hospital from August 2009 to April 2012. 3-tesla MR images including susceptibility-weighted imaging (SWI), DIR and 3D- FLAIR were reviewed. Results: CMIs were found in 9 of 36 (25%) patients. Most CMIs were located in close proximity to lobar microbleeds. Cortical superficial siderosis was observed in 6 of 36 (16.6%) patients, among which 5 (83.3%) showed CMIs. There were 5 patients with symptomatic subcortical hemorrhage, and 3 of these (60%) showed both CMIs and superficial siderosis. Conclusions: These results indicate that CMIs strengthen radiological diagnosis of CAA if these lesions coexist with multiple strictly lobar microbleeds and cortical superficial siderosis.

The complex refractive index of liquid and solid Sb2Te3 around its melting point has been measured by spectroscopic ellipsometry. The real and imaginary parts of the complex refractive index of liquid Sb2Te3 are totally different from those of solid Sb2Te3. The imaginary part of the complex refractive index for the liquid is significantly lower than that of the solid over the observed wavelength range. Our results are consistent with the idea that a molten area created in the center of a focused laser spot can function as a small aperture in the super-resolution readout effect in optical disks.
