Purpose Although automobile production has increased since the development of the Korean automobile industry, the number of customers who can purchase automobiles decreases relatively. Therefore, automobile companies need to develop strategies to attract customers and promote their repurchase behaviors. To this end, this paper analyzed customer data from a Korean automobile company using data mining techniques to derive repurchase strategies. Design/methodology/approach We conducted under-sampling to balance the collected data and generated 10 datasets. We then implemented prediction models by applying a decision tree, naive Bayesian, and artificial neural network algorithms to each of the datasets. As a result, we derived 10 patterns consisting of 11 variables affecting customers' decisions about repurchases from the decision tree algorithm, which yielded the best accuracy. Using the derived patterns, we proposed helpful strategies for improving repurchase rates. Findings From the top 10 repurchase patterns, we found that 1) repurchases in January are associated with a specific residential region, 2) repurchases in spring or autumn are associated with whether it is a weekend or not, 3) repurchases in summer are associated with whether the automobile is equipped with a sunroof or not, and 4) a customized promotion for a specific occupation increases the number of repurchases.

In Product Liability law, the 'defection' of the manufactured products is its key concept, defined in detail. The concept had been already developed through the precedents and theories for the past years even before the PL law was enacted and the concept was listed. Especially, the medicine products need the different approach, because they might directly harm to the human life and body due to their being injected or taken, unlikely other manufactured articles. Since the medical products have the double contradictory functions such as effects and side effects, the defection decisions become so difficult. However, because there are high concerns that wrong medical products will directly harm the human life and body, the decision standards should be more strengthened. The decision standards should include the risk-effect standard as the considered components and make the customer-expecting standard as the final standard. The decision time for defection should be made considering the science technology level when the medical products were provided, not when the accident occurred. It is the most important for the manufacturers to prevent the damages by making and selling the non-defective medicine products for themselves, rather than by taking the legal remedy means afterwards. Therefore, the non-defective guidelines for the medicine manufacturers will help increase the effects and minimize the side-effects.

The study investigates how marketing mix factors are mediated by health consciousness and service quality in creating fresh fruit buying decisions of customers in Vietnam. This study employs samples of customers in Vietnam via the survey questionnaire. The authors have used a total of 256 responses that acquired the valid criteria. The compound of data analysis comprises reliability test, validity test, exploratory factor analysis, group analysis and multiple regression analysis to structure the hypothesized model. Respectively, the structural equation model (SEM) is applied to conduct the multiple multivariate equations. By the assumption of causal-effect relationship between independent variables such as marketing mixed factors, and mediator as health consciousness and service quality, which potentially impact on purchase decision; the SEM method is deployed. The results reveal that consumers have paid no attention to the marketing mix factors, but they care much about service quality and health consciousness. Thus, health consciousness and service quality are effective mediators. These findings are new and contribute to the consumer behavior and retail marketing literature. The findings of this study can provide assistance to managers in the given field to understand more easily the consumer behavior about fresh fruits, then improve their own performance.

This study focuses on identifying and prioritizing the broader performance measures for the service supply chains by taking the case of Majan Electricity Company, Sohar, in the Sultanate of Oman. For an examination of the uniformity of ultimate objectives and the priorities therein, two strata of respondents with a total of fourteen respondents were approached for their valuable insights. Suitable structured instruments were personally administered to elicit the insightful and worthy responses. The two multi-criteria decision-making techniques, namely, the Fuzzy Analytical Hierarchy Process and the Best-Worst Method were used to reach a meaningful prioritization of the identified and refined broader performance measurement dimensions. The results show that there exists a minor gap between the two respondents' groups in terms of their prioritizations. The major finding points to the difference in terms of the topmost priorities as revealed by the two set of respondents. For one group of respondents, the customer satisfaction matters the most, whereas for the other group, it is the overall profitability that matters the most. This gap against the utopian state assists in concluding that there is a requirement to reorient the employees so as to have a shared and common understanding of the organizational priorities.

Recently increasing in marketing or policy decision is the trend of reflecting big data, which, however, has yet to be used directly for the location analysis of public facilities in terms of urban planning. This study examined how the local currency big data, issued often recently by municipalities throughout the country, can be used for the decision-making to select the location of public facilities more rationally. It is such an interesting attempt to acquire the big data of local currency payments by local residents and directly apply it to analyzing the location analysis of public facilities they use. The big data of local currencies which are issued by most municipalities now in Korea will continue to extend its role as the public data. Relatively easily available for municipalities with low cost, it is expected to be used for various policy decisions in future. Although the analysis of big data can make more accurate results than conventional survey methods, however, local residents' participation should not be scaled down in policy decisions. Rather, they should be given the findings of this kind of scientific survey so as to extend the citizen-participatory decision-making model.

The main objective of this study is to design port marketing strategy for strengthening the competitive power of container terminals. The results of this study were found as follows: Firstly, port authority should establish user-oriented operation policy of terminal as the means of activating the opinion window, using terminal monitoring system(TMS). Secondly, terminal planning and development of government should be made to minimize the lead time, to induce the civil capital and to utilize the economies of scale. Thirdly, port authority needs to endeavor to analyze the information of competing foreign terminals as well to promote the concentrated marketing for the terminal on the users, to train the expert and to develop the new port charge system.
