Medical treatment for the aged has become an increasingly important concern as the aged population continues to grow. However, little research has been done on the issue. This study examines the roles of the expertise, convenience, and interaction of medical treatment systems applied by geriatric hospital. Medical treatment systems include oriental medicine, western medicine and integrated(oriental and western) medicine practices. The empirical results of the study are as follows. First, the relative impacts of the expertise, convenience and interaction on customer satisfaction are different depending upon the medical treatment systems. Second, convenience and interaction are shown to be more important factors in western medicine, while interaction is the case in oriental medicine. As for the integrated medicine practices, expertise is considered more important. Thus, it is necessary for the western medicine to make more efforts on interaction and convenience, while it is critical to enhance medical personnels' service quality in the oriental medicine. In the integrated medical treatment, actual and effective cooperation should be achieved to secure expertise. Third, the data demonstrate that customer satisfaction has a positive influence on relationship quality which, in turn, impacts on repurchase intention. Finally, relationship quality has a negative influence on intention to switch in the western medicine, whereas the impact of relationship quality is not significant in the oriental and integrated medicine practices.

This study conducted a survey to analyze the influence of the consumer-brand interaction and the consumer-brand relationship on motivation and satisfaction based on the perceived age of men and women in their teens and 50s who subscribe to cosmetic brands through SNS accounts. For statistical processing of the collected data, frequency analysis, factor analysis, reliability analysis, regression analysis, and multiple regression analysis were performed with SPSS 21.0. The perceived age of the subjects was classified into 'perceived lower group', 'perceived middle group', and 'perceived higher group' according to the difference between the age perceived by others and the age perceived by themselves. In the three groups, the consumer-brand interaction and the consumer-brand relationship showed a meaningful positive relationship with motivation, and the consumer-brand relationship was found to be a major variable explaining 'attractive' among motivation. In the three groups, the consumer-brand interaction and the consumer-brand relationship showed a significant positive relationship with satisfaction, and the consumer-brand relationship appeared as a major variable explaining satisfaction. Therefore, the conclusion of this study is that by perceived age group, the consumer-brand interaction and the consumer-brand relationship have a positive effect on motivation and satisfaction. In particular, it was found that the consumer-brand relationship is a major variable in cosmetics motivation and satisfaction. As this study empirically analyzes the influence of age perceived on SNS on cosmetics brand marketing, it is considered to be a practical implication for establishing cosmetics sales strategy and basic data that can be used for marketing.

Considering the complex structure and high volatility in the shipping market, it is important to investigate the connectedness amongst influencing factors. This study explores the dynamic relationship between supply-demand factors and shipping freight indices. We choose Capesize and Panamax in the bulk carrier market and use quarterly data of GDP, world fleet, BCI, and BPI from 1999 to 2021. Applying the wavelet analysis and wavelet Granger causality test, the simultaneous examination of co-movement and causality between two factors and the shipping market in both the time and frequency domains is achieved. We find that co-movement and causality vary across time and frequencies, thereby existing dynamic relationships between variables. Second, compared to multiple coherencies using demand and supply factors together, partial coherencies indicate noticeable causalities. It implies that analyzing demand and supply factors separately is essential. Finally, shipping freight indices show a high correlation with the demand factor in a good market and with the supply factor in a bad market. Generally, GDP positively leads shipping freights in the recovery phase while the world fleet negatively leads shipping freights in the downturn. The research is meaningful in that the rarely-applied wavelet analysis is adopted in the shipping market and that it gives a reasonable ground to explain the role of supply and/or demand factors in different phases of the market cycle.
