Among the entertainment and media market, it can be observed that animations, comics, and video games (hereinafter abbreviated as ACG) have the highest output value and most market influence. Moreover, ACG also incorporates various industries and creates many derivative products. As the ACG industry emphasizes acousto-optics, imagery, and storylines, personal impressions derived from consumer experiences will influence consumer decisions. In addition, the ACG industry is mainly marketed towards younger age groups, with younger people being the main consumers; as such, these consumers’ decisions are more easily affected by peer behavior. This study aims to analyze the effects of internal cognitions and external influences on buying behavior of ACG consumers by applying the uncomplicated decision tree data mining algorithm. We analyze and develop the target attributes on measures of customer loyalty for ACG industry to set up the decision trees from the collected questionnaire data. The decision tree data mining method is applied to analyze the hidden association rules between the target attributes (i.e., consumer loyalty) and the critical influencing factors of consumer’s internal impressions and external influences for ACG consumers. The results and suggestions of this paper can be used as a reference for enterprises in the ACG industry to help with business policies concerning products’ extensional design, marketing, and CRM, and to further strengthen customer satisfaction and loyalty, thus increasing company profits.

Abstract: A novel imidazolium-based ionic liquid (IL), covalently bound to catechol (CA) groups by carbodiimide-mediated coupling reactions, was synthesized and used as the electrochemical sensing probe for dihydronicotinamide adenine dinucleotide (NADH). The thin layer of the CA-functionalized IL (IL-CA) at the screen-printed carbon electrode (SPCE) exhibited a stable redox couple originating from the catechol/quinone at the terminus. The redox-active film-modified electrode exhibited high and persistent electrocatalytic activity at 0.32V for the oxidation of NADH in pH 7.0 buffer solutions, while the oxidation reaction occurred at 0.75V at the bare electrode. Moreover, the modified electrode also showed free of interference from ascorbic acid (AA) and uric acid (UA). Flow-injection amperometry was performed for 1–1000μM of NADH under optimized conditions, and a linear calibration plot with a slope of 0.0078μA/μM was obtained. The detection limit (S/N=3) was 0.4μM. [Copyright &y& Elsevier]
