Association rule mining techniques enable us to acquire knowledge concerning sales patterns among individual items from voluminous transactional data. Certainly, one of the major purposes of association rule mining is utilizing the acquired knowledge to provide marketing strategies such as catalogue design, cross-selling and shop allocation. However, this requires too much time and high cost to only extract the actionable and profitable knowledge from tremendous numbers of discovered patterns. In currently available literature, a number of interest measures have been devised to accelerate and systematize the process of pattern evaluation. Unfortunately, most of such measures, including support and confidence, are prone to yielding impractical results because they are calculated only from the sales frequencies of items. For instance, traditional measures cannot differentiate between the purchases in a small basket and those in a large shopping cart. Therefore, some adjustment should be made to the size of market baskets because there is a strong possibility that mutually irrelevant items could appear together in a large shopping cart. Contrary to the previous approaches, we attempted to consider market basket's size in calculating interest measures. Because the devised measure assigns different weights to individual purchases according to their basket sizes, we expect that the measure can minimize distortion of results caused by accidental patterns. Additionally, we performed intensive computer simulations under various environments, and we performed real case analyses to analyze the correctness and consistency of the devised measure.

We use a scale mainly for quantification when we study the psychological characteristics that we cannot observe. The utilization of a scale is frequent in scientific educational studies. The convenience offered by Likert scale, which is among the most frequently used, enable us to grasp characteristic attitude or recognition in students, and evaluate them against an affective domain. But a lot of errors occur, and has been noted as well in the case of utilizing Likert scale in the process. A central tendency in the utilization of Likert scale appears in this study, and the trend analyzes according to study objects and study contents, but we intend to find a way to utilize Likert scale. The results of study made on our countryside students show that the answers tend to get concentrated and a central tendency appears. Our countryside students were aware of the eyes surroundings them, have respect for elders through social experiences, and have had troubles with differentiated expression or personality in the group and cultural environments. According to the object of study, the central tendency appears more among older students than younger students, more among general students than gifted students. In the contents of study, the central tendency has been given more appearance in scope and their exposure has relatively been in large domain. Therefore when utilizing Likert scale in scientific education study, an error of central tendency appears as if they are results of the study. So, when applying the Likert scale to scientific study, we need to consider sociocultural environment, characteristics of an object and contexts of study. This enables avoiding dependence on numerical value of the utilization results, and interpret them correctly.

The purpose of this study is to validate scale of deteminants for watching Korean traditional music performances to activate the market by procuring and increasing Korean traditional music performance consumers that exhibit generally low preference in the performance market. Accordingly, FGI was conducted on seven employees and professionals in the arts and cultural sector and then open survey results were categorized into eight factors and a total of sixty-five items using the KJ method to find the viewing decision factors per consumer type of Korean traditional music performances. Afterwards, a six-factor and thirty-five items were extracted after conducting an exploratory factor analysis and confirmatory factor analysis was conducted to verify the structural appropriateness, and then the feasibility of the composition of Korean traditional music performance viewing decision factor scale was verified. Results of the analysis showed that first, for general Korean adults making decisions to view Korean traditional music performances, there was positive impact in the order of interest-creating factors, fame and talent factors, emotional and information factors, creativity factors, reasonable price factors, and social relation factors. Second, the general tendency of decision factors to view Korean traditional music performances showed relatively high levels in reasonable price factors and interest-creating factors among the Korean traditional music performance viewing decision factors, while emotional and information factors were found to be relatively low.

The debate surrounding advertising effectiveness is not to be overstated as a major source of advertising research. However, there is still a lack of discussion on the model for measuring the effects of government and public service advertising. This study focuses on this point and develops an index model that can evaluate government advertising. For this purpose, we conducted a survey of 800 respondents in 7 major cities. Based on the creativity evaluation factors (originality, clarity, and appropriateness) of government advertising and the evaluation factors (interest, avoidance, and relevance) of policy contents, a causal model that affects the cognition, attitude, and behavioral responses of the audience was set up. As a result of analysis, originality, clarity, interest, and relevance except for appropriateness and avoidance were meaningful variables for creating government advertising effect such as policy understanding, audience attitude, word of mouth intention of policy. In addition, policy understanding and audience attitude were the main mediating variable influencing the word of mouth intention of policy. Based on research results, this paper discussed the direction for creating effective government and public service advertising in the future.

The current study investigated multiple dimensions of brand personality for kids' fashion brands according to the brand personality scale of Aaker (1997) through an online survey of 500 women in their 20s to 40s raising children. The extracted brand personality factors, such as sincerity, competence, and excitement, showed positive and direct effects on brand loyalty. However, while sincerity and excitement turned out to have indirect effects mediated by brand identification on brand loyalty, competence did not have significant indirect effect. However, as a result of examining the moderated mediating effect according to the child's gender on the brand personality's mediating effect, in case of daughters, the effect of competence was strengthened, whereas the effects of sincerity and excitement were turned out to be increased in case of sons.

The purpose of this study is to identify how learners perceive mobile technology-based learning materials. For this purpose, two methods were utilized. Using multi-dimensional scale(MDS), it was identified that how learners perceive each type of learning materials using mobile technology. Through semantic differential scale(SDS), learners' perception of the difference between mobile learning materials and existing traditional learning materials was analyzed. As a result, learning materials using mobile technology were classified into as follows : the dimension of interaction with the content; the sense of presence. Learners perceived that mobile learning materials had characteristics of 'active', 'learner-centric', 'multi-sensory', and 'stimulating interest'. The significance of this study was to empirically and comprehensively investigate learners' perception for the characteristics of various mobile learning materials.
