「ミクロ→マクロ」に関する方法論的検討

In the field of higher education, there are many studies that seek to contribute to policy and practice. In this pursuit, research in higher education studies tends to have both micro and macro aspects. However, the relationship between micro behavior and macro phenomena is not self-evident, and conventional research shows methodological shortcomings. This research focuses on how the micro foundations of macro issues can be identified from a methodological perspective, and examines the limitations, possibilities, and suitability of the simulation approach, especially agent-based model (ABM) for higher education research. First, this paper will re-frame the discussion on the formulation of micro-macro mechanisms in the real world and organize it from the methodological viewpoint of how to quantitatively describe the mechanisms and contradictions contained in the “micro to macro” process. In section two, we will organize the development of the debate on the micro-macro issue and the points of contention from the viewpoint of social science methodology. Section three focuses on the process by which the concept of concrete macro is constructed and analyzes the difficulties in quantitative descriptions of “micro to macro”. Based on these discussions, section four focuses on the research methods utilized in “micro to macro” analysis and presents the applicability and problems of Agent Based Model (ABM)

A 3D-Printed Fin Ray Effect Inspired Soft Robotic Gripper with Force Feedback

Soft robotic grippers are able to carry out many tasks that traditional rigid-bodied grippers cannot perform but often have many limitations in terms of control and feedback. In this study, a Fin Ray effect inspired soft robotic gripper is proposed with its whole body directly 3D printed using soft material without the need of assembly. As a result, the soft gripper has a light weight, simple structure, is enabled with high compliance and conformability, and is able to grasp objects with arbitrary geometry. A force sensor is embedded in the inner side of the gripper, which allows the contact force required to grip the object to be measured in order to guarantee successful grasping and to provide the most suitable gripping force. In addition, it enables control and data monitoring of the gripper’s operating state at all times. Characterization and grasping demonstration of the gripper are given in the Experiment section. Results show that the gripper can be used in a wide range of scenarios and applications, such as the service robot and food industry

Rapid detection of single bacteria in unprocessed blood using Integrated Comprehensive Droplet Digital Detection

Blood stream infection or sepsis is a major health problem worldwide, with extremely high mortality, which is partly due to the inability to rapidly detect and identify bacteria in the early stages of infection. Here we present a new technology termed 'Integrated Comprehensive Droplet Digital Detection' (IC 3D) that can selectively detect bacteria directly from milliliters of diluted blood at single-cell sensitivity in a one-step, culture- and amplification-free process within 1.5-4h. The IC 3D integrates real-time, DNAzyme-based sensors, droplet microencapsulation and a high-throughput 3D particle counter system. Using Escherichia coli as a target, we demonstrate that the IC 3D can provide absolute quantification of both stock and clinical isolates of E. coli in spiked blood within a broad range of extremely low concentration from 1 to 10,000 bacteria per ml with exceptional robustness and limit of detection in the single digit regime
