The sterilization of health care products is widely used to choose conventional Ethylene Oxide gas sterilization in South Korea. But the method has brought serious issues because of the toxic residual gas and global warming of $CO_2$ evacuation after the sterilization process. This study is carried out to confirm the application possibility of gamma sterilization instead of Ethylene Oxide in sanitary aid products. Four kinds of products (gauze, menstrual pad, bandage, menstrual tampon) were treated with gamma irradiation of 15 kGy, then analyzed the achievement of the sterility assurance level (SAL) $10^{-6}$ through BI test. The cytotoxicity of accelerated samples of 6 months elapse evaluated by means of colony forming rate at various concentration of the extracts. pH and UV measurements at extract concentrations were tested according to the MFDS (Ministry of food & drug safety) guideline to verify a stability & safety of product sterilized. The results revealed that the extracts did not show any significant changes in cytoxicity assay as well as pH and UV values by gamma sterilization. All extract concentration was observed high cell viability, pH and UV values were calculated within the acceptable range prescribed by the guideline. It indicates that gamma sterilization could effectively substitute for conventional sterilization such as Ethylene Oxide sterilization in the sanitary aid products.

The production of hydrogen via water electrolysis (i.e., green hydrogen) using renewable energy is key to the development of a sustainable society. However, most current electrocatalysts are based on expensive precious metals and require the use of highly purified water in the electrolyte. We demonstrated the preparation of a non-precious metal catalyst based on CuCo₂O₄ (CCO) via simple electrodeposition. Further, an optimization process for electrodeposition potential, solution concentration and electrodeposition method was develop for a catalyst-substrate integrated electrode, which indicated the highly electrocatalytic performance of the material in electrochemical tests and when applied to an anion exchange membrane water electrolyzer.

In the midst of increasing interest in the environmental responsibility of companies, this study investigates how eco-friendly activities affect the creation of management performance. To this end, the effect of companies' green marketing on consumers' word-of-mouth intention, the mediating effect of brand reliability, and the moderating effect of consumers' pro-environmental behavior were verified. The results of the collected data analysis are as follows. First, companies' green marketing has a positive (+) effect on consumers' word-of-mouth intention. Second, brand reliability takes a positive (+) mediating role in the relationship between companies' green marketing and consumers' word-of-mouth intention. Third, consumers' pro-environment behavior has a moderating role between Brand Reliability and their word-of-mouth intention. Therefore, companies' eco-friendly strategies and their implementation will help enhance both brand reliability and consumers' word-of-mouth intention. By revealing the effect of companies' eco-friendly strategies and their implementation on brand reliability and consumers' word-of-mouth intention it is meaningful to analyze the relationship between green marketing and the possibility of consumers' spontaneous word-of-mouth intention. The results suggest to companies that it is necessary to establish an eco-friendly marketing strategy for sustainable growth.
