    The center of community (COC) program proposed by the University of Fukui was selected by the Japanese government, specifically, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) in 2013. The COC program aims at gathering various human resources, information, and technology, thereby providing the regional society with a basis for developing human resources, manufacturing (industry promotion/technology management), regional medical care, creating a sustainable society and the environment, developing human resources in the nuclear-power related fields and establishing disaster prevention systems. We have examined and practiced a new style of education for mathematical science and partnership between the university of Fukui and high schools in Fukui prefecture from an international perspective. We have developed teaching materials and mathematical problems rooted in the community. Moreover, we have collaborated with the mathematical innovation enterprise in biomedical engineering and industries, Project Research Center in School of Engineering, University of Fukui to identify and nurture next-generation researchers who shall be responsible for mathematical innovation in biomedical engineering and industries.

    In 2014-15, our COC project held workshops to realize mathematical needs specialized in these fields. Workshops entitled "Discovery of Mathematical Needs on Health Promotion," "Investigation of Geometric Methods to Understand/Control Cellular Systems," and "Development of Mathematical Models for Utilizing Medical Big Data Obtained from Wearable Equipments" were jointly conducted by the Society for Science on Form and supported by CoopMath, a project commissioned by the MEXT.

    A special issue, titled, "Special Issue: Form on Multiscale Biosystems and Functions," which is a collection of papers presented at workshops as well as newly contributed papers related to the symposium theme, has been published. In particular, it comprises two original papers and four forums. Its contents cover aspects of form, such as stereoscopic vision and displays, bio-signals, design/evaluation for daily health care, neural networks, and a new style partnership for mathematical education. It is our hope that this issue contributes to future advancements in the Society for Science on Form.

    It is understood that the number of students who come to dislike science and mathematics increases as students age. Classes that stimulate intellectual inquisitiveness and inquiring minds are important in order to increase the number of students who are interested in science, arithmetic, and mathematics. However, as globalization gathers speed for the international economy of the 21st century, it is of great necessity to continuously develop global human resources who possess communication skills, intercultural experiences, and mathematical ways of thinking. There is a compelling need for high schools and universities to develop and train global talent for employment opportunities in the government and companies. Therefore, the purpose of this paper is to clarify the capabilities and conditions of global human resources and to propose such talents can be developed in both high schools and universities in Japan.

    In contrast to two-dimensional (2D) films that project flat images, stereoscopic films elicit the feeling of being at a live performance. However, asthenopia and visually-induced motion sickness (VIMS) can result from the exposure to these films. Even though various hypotheses exist, the pathogenesis of VIMS is still unclear. There is not enough knowledge on the effects of stereoscopic images on the living body, and the accumulation of basic research is thus important. The aim of this paper is to accumulate information relevant to VIMS and to examine whether the exposure to 3D video clips affects the human equilibrium functions. We also verified that 3D viewing effects on our equilibrium function depends on exposure time.

    It is gaining great importance to develop and integrate physiological sensors into daily healthcare. Especially, electrocardiogram (ECG) is useful for the disease diagnosis and daily health monitoring, also for the driver's cognitive state monitoring. Capacitive ECG monitoring system, which enables to collect ECG with indirect skin contact, is implemented in this study. Signal attenuation and noise contamination is considered by installing flexible electrode, neutralization circuit, AC coupling circuit, Driven right leg (DRL), and DSP board in the configuration. The system is evaluated with 5 subjects with a car in situations of engine off and on. R-wave Detection Sensitivity (Se) and Positive Predictivity (P+) of 99.8% and 100% were obtained during the engine on.

    Regulation of branched axonal arbor shape is crucial for proper neuronal wiring as well as for nervous system plasticity. Isolated neurons are capable of extending axons and establishing complicated branched axonal morphology even without cell-extrinsic cues. This occurs by differentially regulating the growth of each terminal in an arbor. However, the mechanisms governing this cell-autonomous process are not fully understood. Here, I present recent findings regarding the intracellular mechanisms mediating terminal-dependent control of growth and retraction in the single axonal arbor.

    Cell migration is a fundamental process that orchestrates embryonic development and drives cancer invasion and metastasis. Rho small GTPases (Rac, Cdc42, and Rho) regulates cell migration through remodeling of the actin cytoskeleton. Rho GTPase activating proteins (GAPs) are negative regulators of RhoGTPases. FilGAP is a GAP for Rac and binds to Filamin A. Emerging evidences suggest that FilGAP may regulate organization of the actin cytoskeleton in a spatiotemporal manner. In this paper, we describe the recent findings on the role of FilGAP in the regulation of cell morphology and migration and its regulatory mechanism.

    The influence of 3-D images on body sway was investigated using videos of complex sphere movement in space and Smart glass. In addition, perspective clues were added to the videos and the influence on body sway was compared. Significant changes in analytical parameters were noted when the videos without spheres at the 4 corners giving no perspective clue were presented, showing that the standing position control system became unstable while viewing the video without perspective clues, compared to that while viewing them with such clues. On comparison between the 2D and 3D videos, significant changes were noted in the elderly group in the test with open eyes while viewing the video without perspective clues, but no significant change was noted in the young or middle-aged subjects.
