BREAKING DOWN BARRIERS: PROPOSALS FOR OVERCOMING CHALLENGES IN STUDENT PROJECT MANAGEMENT

Student project management is becoming increasingly important in various settings such as technical clubs, planning clubs, and research laboratories. However, effective methodologies for managing student-led projects have not yet been established. This study aims to address key issues related to cost and motivation in student-led projects and propose effective improvement plans. The significance of this study lies in its potential to identify challenges faced in current student project management practices and offer solutions to mitigate risks. By sharing our findings, we aim to encourage further research on this topic and promote the adoption of effective methodologies for managing student-led projects.  Article visualizations

RECONSIDERATION AND PROPOSAL OF DEVELOPMENT MODELS IN PROJECTS - “QUASI” DEVELOPMENT MODELS: QUASI-WATERFALL AND QUASI-AGILE

Diverse development models, including waterfall development, iterative development, and agile development, have been put forth and implemented across real-world contexts. When engaging in discussions on project management, the examination and exploration of development models assume paramount importance and are integral. This paper embarks upon an investigation and scrutiny of these development models, culminating in the proposition of "Quasi" Development Models: Quasi-Waterfall and Quasi-Agile.  Article visualizations

This paper presents an analysis of the difficulties encountered in the realm of ICT education in Japan, taking into account ten different perspectives.  Article visualizations

Matroid, Ideal, Ultrafilter, Tangle, and so on: Reconsideration of Obstruction to linear decomposition

The investigation of width parameters in both graph and algebraic contexts has attracted considerable interest. Among these parameters, the linear branch width has emerged as a crucial measure. In this concise paper, we explore the concept of linear decomposition, specifically focusing on the single filter in a connectivity system. Additionally, we examine the relevance of matroids, antimatroids, and greedoids in the context of connectivity systems. Our primary objective in this study is to shed light on the impediments to linear decomposition from multiple perspectives.Comment: 11 page

Internal Transport Barrier in Tokamak and Helical Plasmas

The differences and similarities between the internal transport barriers (ITBs) of tokamak and helical plasmas are reviewed. By comparing the characteristics of the ITBs in tokamak and helical plasmas, the mechanisms of the physics for the formation and dynamics of the ITB are clarified. The ITB is defined as the appearance of discontinuity of temperature, flow velocity, or density gradient in the radius. From the radial profiles of temperature, flow velocity, and density the ITB is characterized by the three parameters of normalized temperature gradient, $R/{L}_{T}$, the location, ${\rho }_{\mathrm{ITB}}$, and the width, W/a, and can be expressed by \u27weak\u27 ITB (small $R/{L}_{T}$) or \u27strong\u27 (large $R/{L}_{T}$), \u27small\u27 ITB (small ${\rho }_{\mathrm{ITB}}$) or \u27large\u27 ITB (large ${\rho }_{\mathrm{ITB}}$), and \u27narrow\u27 (small W/a) or \u27wide\u27 (large W/a). Three key physics elements for the ITB formation, radial electric field shear, magnetic shear, and rational surface (and/or magnetic island) are described. The characteristics of electron and ion heat transport and electron and impurity transport are reviewed. There are significant differences in ion heat transport and electron heat transport. The dynamics of ITB formation and termination is also discussed. The emergence of the location of the ITB is sometimes far inside the ITB foot in the steady-state phase and the ITB region shows radial propagation during the formation of the ITB. The non-diffusive terms in momentum transport and impurity transport become more dominant in the plasma with the ITB. The reversal of the sign of non-diffusive terms in momentum transport and impurity transport associated with the formation of the ITB reported in helical plasma is described. Non-local transport plays an important role in determining the radial profile of temperature and density. The spontaneous change in temperature curvature (second radial derivative of temperature) in the ITB region is described. In addition, the key parameters of the control of the ITB and future prospects are discussed

Plant Mitochondrial-Targeted Gene Delivery by Peptide/DNA Micelles Quantitatively Surface-Modified with Mitochondrial Targeting and Membrane-Penetrating Peptides

Plant mitochondria play essential roles in metabolism and respiration. Recently, there has been growing interest in mitochondrial transformation for developing crops with commercially valuable traits, such as resistance to environmental stress and shorter fallow periods. Mitochondrial targeting and cell membrane penetration functions are crucial for improving the gene delivery efficiency of mitochondrial transformation. Here, we developed a peptide-based carrier, referred to as Cytcox/KAibA-Mic, that contains multifunctional peptides for efficient transfection into plant mitochondria. We quantified the mitochondrial targeting and cell membrane-penetrating peptide modification rates to control their functions. The modification rates were easily determined from high-performance liquid chromatography chromatograms. Additionally, the gene carrier size remained constant even when the mitochondrial targeting peptide modification rate was altered. Using this gene carrier, we can quantitatively investigate the relationships between various peptide modifications and transfection efficiency and optimize the gene carrier conditions for mitochondrial transfection

The Origin of Ripples in Cool Cores of Galaxy Clusters: Heating by MHD Waves?

We consider MHD waves as a heating source of cool cores of galaxy clusters. In particular, we focus on transverse waves (Alfven waves), because they can propagate a longer distance than longitudinal waves (sound waves). Using MHD simulations, we found that the transverse waves can stably heat a cool core if the wave period is large enough (>~ 10^8 yr). Moreover, the longitudinal waves that are created as a by-product of the nonlinear evolution of the transverse waves could be observed as the 'ripples' found in cool cores.Comment: Accepted for publication in ApJ

Intraoperative Changes in Idiopathic Macular Holes by Spectral-Domain Optical Coherence Tomography

Purpose: To examine anatomical changes in idiopathic macular holes during surgery using handheld spectral-domain optical coherence tomography (SD-OCT). Methods: Five eyes of 5 patients who underwent surgery for the repair of idiopathic macular holes were examined. The surgery included standard 25-gauge, 3-port pars plana vitrectomy, removal of the internal limiting membrane (ILM), fluid-air exchange, and 20% sulfur hexafluoride tamponade. Intraoperative SD-OCT images of the macular holes were obtained after ILM removal and under fluid-air exchange using a handheld SD-OCT. From SD-OCT images, the macular hole base diameter (MHBD) was measured and compared. Results: All macular holes were successfully closed after the primary surgery. The mean MHBD under fluid-air exchange was significantly smaller than the mean MHBD after ILM removal and the preoperative mean MHBD. In 1 eye with a stage 3 macular hole, SD-OCT images revealed that the inner edges of the macular hole touched each other under fluid-air exchange. Conclusion: Fluid-air exchange significantly reduced MHBD during surgery to repair macular holes. Fluid-air exchange may be an important step for macular hole closure as it reduces the base diameter of the macular hole
