In recent business activities, well-being-based management approaches have become increasingly important. Consideration of consumer well-being is one of them. In particular, social demand and interest in health are incredibly high, and the health-related services market has significantly expanded. However, since the WHO's definition of health was established, the concept of health has become multi-dimensional. There is much overlap with other concepts, such as well-being and quality of life. As a result, even for health-related services that are supposed to contribute to consumers' health, the critical term "health" is still used ambiguously by both service providers and consumers. It could increase the uncertainty of the benefits of the services and cause difficulties in the continued use of services for consumers.

Several practical applications of melt-textured bulk superconductors require the complex-shaped products such as curved, ring-shaped, and drilled blocks rather than simple shaped pellets. However, melt-textured bulk superconductors are often damaged when they are cut, grinded, or drilled. With the aim of reducing such damages, we have investigated the preparation of the complex-shaped bulk superconductors by previously machining binder-added precursors and pre-sintered precursors. We could produce various complex-shaped bulk superconductors without cracking from these machined precursors
