The ISO 9000 Quality Management System(QMS) standard is an effective tool that can consistently meet the various requirements of stakeholders and promote customer satisfaction management. However, in the recent business environment, not only quality issues but also risks in various other areas are increasing. In particular, risks related to product safety problems which are arised from product convergence, diversification of methods of production and globalization of supply chain pose a great threat to the sustainability of companies. Accordingly, ISO published standards of Product Safety Management System(PSMS) for suppliers such as ISO 10377 and ISO 10393. This study aims to suggest an integration framework of QMS and PSMS based on ISO international standards. To this end, the relationship of QMS and PSMS are analyzed and the requirements of the both systems are integrated based on the Plan-Do-Check-Act(PDCA) cycle and risk-based thinking. In addition, guidelines that can systemize the integrated requirements are presented in the aspect of processes and documentation. This study is expected to be used as a guideline that helps companies that have already acquired QMS certification to build an international level product safety management system early.

Here, Zn ferrite is synthesized along with reduced graphene oxide (rGO) by a facile one-step hydrothermal method. The difference between the synthesized nanocomposites with those in other reported work is that the reaction conditions in this work are 160 oC for 12 h. The synthesized products are characterized by field-emission scanning electron microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and attenuated total reflection. Further, the adsorption property of rGO–Zn ferrite (rGZF) nanocomposite is studied after confirming its successful synthesis. The adsorption capacity of rGZFs toward rhodamine B (RB) is ˃ 9.3 mg/g, whereas that of bare ZF nanoparticles is 1.8 mg/g in aqueous media. The efficiencies of rGZF and bare ZF to remove RB are 99 % and 20 %, respectively. Employing rGZF, 60 % of RB is decomposed within 5 min. The kinetic study reveals that the adsorption process of removing RB by bare Zn ferrite follows pseudo-firstorder kinetics. However, after zinc ferrite is incorporated with rGO, the kinetics changes to pseudo-second-order. Furthermore, the Langmuir isotherm is accomplished by the adsorption process employing rGZF, indicating that a monolayer adsorption process occurs. The thermodynamic parameters of the process are also calculated.
