研究評価における数値指標（Metrics）への偏重は，ミスコンダクトや疑わしい研究活動の要因である。学術論文数は急増しているが，その一方で，

Research integrity is the basis of scientific research practice. These days excessively competitive research environment has generated a negative impact on scientific research including the prevalence of superficial science and research misconduct. Research misconduct does cause serious damage not only to research activity but also to social activity, such as medical care and developing human resources. We could promote research integrity in two integral directions; the researchers' sincere attitude and the system in which reliable science is encouraged. In the former direction, researchers should revisit the significance of the Mertonian norms (CUDOS; Communism, Universalism, Disinterestedness, and Organized Skepticism), which represent how researchers should put the self-correction of science into practice. In the latter direction, the scientific community should consolidate the system, such as education of science history, recognition of the significance of slow science, encouragement of open science, placement of research integrity advisers, and fulfilling institutional supports.

This paper contains a series of essays which form a synopsis of my research career, which has been dedicated to orogenic and metamorphic processes in plate boundaries. It also presents my future research directions and latest investigations into simplifying the complexity of metamorphic rocks, their field observations, and associated convergent plate margin dynamics.

 Slab dehydration beneath forearcs and arc has been one of the most exciting problems in the field of convergent plate margin dynamics in recent decades. Orogenic and metamorphic processes are closely related. In the subduction zones, the fluid-mediated processes primarily control the crust-to-mantle transfer of volatiles, redox states of the wedge mantle peridotite and arc magmas, flux-melting to generate arc magmas, and seismicity. Although the methods of classical metamorphic petrology, based on phase equilibrium calculations, and the application of conventional geochronology continue to provide the opportunities to link high-pressure and ultra-high-pressure metamorphism to geophysical observations today, advances in geochemical techniques have great potential for key geological markers in global convergent margins. For example, recent analytical techniques and applications used in studies of metamorphic rocks, such as in-situ Li-B-Sr-Pb spot isotope analyses of jadeite, serpentinite, lawsonite, etc., evaluate hydration and dehydration along the subduction channels and subsequent slab-mantle interaction, and visualize more realistic ancient Pacific-type convergent margins. The scientific value of subduction-zone rocks and crustal rocks are not limited to their worth for geochemistry: Some metamorphic rocks and minerals are important for all realms of geological sciences, from nano-scale kinetics to the scale of mountain building events. Consequently, collaborative exchange among geoscientists, through the application of applying different approaches, tests, and challenges, to address problems related to plate boundaries in the future.
