Purpose - This research is to empirically explore the differences in apparel consumption among male and female teenagers and college students in Korea and China. By conducting a survey to understand customers' needs and behaviors, fashion businesses will be able to improve their customer satisfaction and avoid redundancy, inventory, and the waste of resources, effort and money. Design/methodology - The research design considers the consumption patterns of male and female high school and college students in Korea and China. To analyze the data, the study employs decision trees, a type of machine learning algorithm. A decision tree model was developed to examine the relationship between the explanatory and response variables, which can be either quantitative or qualitative in nature. Findings - The main findings of this study indicate that there are differences in shopping behavior among different customer segments. The results show that men have a simpler shopping behavior compared to women. Additionally, cultural factors and the difference in fashion needs between students and non-students have a significant impact on the shopping choices of Chinese and Korean individuals. Originality/value - Existing studies often assume that the shopping behavior of high school and university students is similar and that there are no significant differences in clothing purchases between men and women across countries. The results provide valuable insights into the unique shopping behavior of different customer segments, and can inform fashion businesses in their efforts to meet the needs of their customers.

This research explores how imported automobile companies can develop their strategies to improve the outcome of their recalls. For this, the researchers analyzed patterns of recall demand, classified recall types based on the demand patterns and examined response strategies, considering plans on how to procure parts and induce customers to visit workshops, recall execution capacity and costs. As a result, recalls are classified into four types: U-type, reverse U-type, L- type and reverse L-type. Also, as determinants of the types, the following factors are further categorized into four types and 12 sub-types of recalls: the height of maximum demand, which indicates the volatility of recall demand; the number of peaks, which are the patterns of demand variations; and the tail length of the demand curve, which indicates the speed of recalls. The classification resulted in the following: L-type, or customer-driven recall, is the most common type of recalls, taking up 25 out of the total 36 cases, followed by five U-type, four reverse L-type, and two reverse U-type cases. Prior studies show that the types of recalls are determined by factors influencing recall execution rates: severity, the number of cars to be recalled, recall execution rate, government policies, time since model launch, and recall costs, etc. As a component demand forecast model for automobile recalls, this study estimated the ARIMA model. ARIMA models were shown in three models: ARIMA (1,0,0), ARIMA (0,0,1) and ARIMA (0,0,0). These all three ARIMA models appear to be significant for all recall patterns, indicating that the ARIMA model is very valid as a predictive model for car recall patterns. Based on the classification of recall types, we drew some strategic implications for recall response according to types of recalls. The conclusion section of this research suggests the implications for several aspects: how to improve the recall outcome (execution rate), customer satisfaction, brand image, recall costs, and response to the regulatory authority.

This study was to examine the degree of market orientated effort by hospital type and size,. and analyzed the moderating effect of environments between market orientation and it's performance. First, there was no significant differences by hospital type, such public hospital, university hospital, and private hospital. However, the orders of market orientation implementation was university hospital. private hospital, and public hospital This finding suggest that university hospital and public hospital, should be market-oriented, or customer-oriented more now, relatively. Second, there were no significant differences in marketing as management policy by hospital types, i.e. public, university or private sector hospitals. However, as to the intensity of the implementation of the market-oriented approach, private hospitals came first, followed by the university hospitals, then the public ones. This finding suggests that university and public hospitals should be more market or customer oriented to compete in the market. Third, only the competitive environment does active moderating roll on hospital performance. The competitive environmental factor forces the organization to be more market oriented. This means the more you are positively situated in the competitive environment, the more you are looking for a market oriented approach. You become more aware of the value of customers and you become more focused on the customer satisfaction and thus become more patient oriented in every facet of decision making. And market oriented hospitals recognize the importance of utilization of high tech medical treatment skills and equipment in patient care. Fourth, according the analysis, market oriented effort gives more influence on hospital performance than the environmental factors. This means that the market oriented effort should become a culture of the hospital which seeks to out distance themselves from its competitors.
