Nanostructured ZnO materials have been studied extensively because of their functional properties. This paper presents a composite material of zinc oxide quantum dots (ZnO QDs) and porous carbon using a one-step carbonization process. The direct carbonization of a metal–organic complex generates mesostructured porous carbon with a homogeneous distribution of ZnO QDs. The structural and morphological properties are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The resulting ZnO QDs@porous carbon composite delivers a high specific capacity of 990 mAh g−1 at 100 mA g−1, 357 mAh g−1 at 2 A g−1, and high reversibility when evaluated as an anode for lithium ion batteries.

It’s a time we prepare for a reparation agenda for Jeju 4.3 victims and their families. We should approach the USA government side collectively rather than individually for their lawsuits, because most of them are elderly, over 75 years old and need intensive medical care and assistance immediately. It’s up for us to recognize some tasks of actualizing Reparation, Reconciliation and Reconnection Agenda for “Environmentally Sustainable Peace Island” beyond Trauma of the Jeju 4.3 Grand Tragedy into the next Decade.

Islanders have tried to find out real alternatives on how to keep sustainable Haenyeo communities through both developing traditional school system at community level (Hansupul Haenyeos School) and advanced school system at university level ( an educational certificate program for Interpreter of Haenyeos Culture and an advanced certificate program for Hanyeos Culture). In oder to share their wisdom of ordinary democratic life style around Bultuk, We created Global Peace Bultuk Assembly for younger generation to succeed in their tradition in July of 2010. It' s a time for us to find out Integrating Policy of the Sustainability of Jeju Haenyeo (Jamnyeo, Jamsu) Community facing their extinction into Jeju Village Conservation Model of Marine Resources Needed.

The purpose of this study is to derive various clues for the establishment of marketing strategies for companies that produce and sell high-involvement products for Millennials who are not the subject of current consumption but who will lead future consumption. For this purpose, this study aimed to derive 17 factors of high-involvement product selection attributes through FGI, and its relationship on repurchase intention after make a variable through PCA. A total of 158 valid questionnaires were used, and IPA, independent sample t-test, regression analysis, and hierarchical controlled regression analysis were performed. The results showed that overall, external and internal selection factors had a positive influence on repurchase intentions, and in particular, appealing to internal and external selection factors in order to promote repurchase intention. Meanwhile, the Millennials were found to have no gender difference. Therefore, the company producing and selling high-involvement products suggests that it is necessary to make a priority effort to secure brand awareness, trust in product producers, store trust, and product self-reputation as components of internal selection factors. It was also concluded that more strategic efforts were needed to focus on and appeal to the characteristics of the Millennial itself rather than to consider gender differences.
