This study tried to find out whether character patterns of elderly people are related to stress resistance using brain waves, personal physiological index of cranial nerves. The data were gathered by 1,108 seniors(age 65 and over) who were requested to check brain waves from September, 2007 to December, 2010 in Korean Institute for Research of Psychiatry. 552 of the subject showed the propensity to positive behavior, 556 of them showed the propensity to negative behavior. 735 of the subject showed the propensity to cheerful emotion, 373 of them showed the propensity to depressed emotion. As a result the propensity of emotion was significantly related to the stress resistance, but not the propensity of behavior. In other words, the propensity to cheerful emotion showed higher average stress resistance index than the propensity to depressed emotion. So the person who has the propensity to cheerful emotion can cope with stress better. This study shows the propensity to emotion is related to stress resistance. The influence of the propensity to emotion and how it works should to be studied.

The purposes of this study were to investigate the emotional consumption propensity and the preferences for sensibility factors of fabrics(color tone, pattern and texture image), and to analyse the differences according to demographic variables and relationships between emotional consumption propensity and preferences for sensibility factors of fabrics, focusing on male and female consumers in 20's, 30's and 40's. The emotional consumption propensity were classified into symbolic consumption propensity, individual consumption propensity, aesthetic consumption propensity and hedonic consumption propensity. The subjects attached great importance in the order of aesthetic consumption propensity, individual consumption propensity and symbolic consumption propensity. Those factors of emotional consumption propensity showed partially significant difference according to demographic variables. Female consumers preferred various color tones than men did, and preference for light color tone showed significant differences according to gender and occupation of consumers. The preferences for floral pattern showed significant difference according to gender, age, education, occupation and marital status of consumers. The factors of the texture images for the fabrics showed partially significant difference according to demographic variables except education of consumers. There were almost significant relationships between emotional consumption propensity and the preferences for sensibility factors for fabrics.

This study compared full-time housewives' propensity for TV home shopping addiction by different socioeconomic, psychological, and purchase-related characteristics. And it identified the factors that influenced full-time housewives' TV home shopping addiction. The data were obtained from a questionnaire completed by full-time housewives (n=225) lived in Seoul and were analyzed by t-tests, ANOVA, and a multiple regression analysis. The findings of this study were as follows: First, full-time housewives' propensity for TV home shopping addiction was higher in the relatively old aged group. Those who graduated from graduate schools had lower scores in the scale of TV shopping addiction. Also, middle income group showed higher propensity for addictive buying. Second, the propensity for TV home shopping addiction was higher among those who had low self-esteem, who had higher level of empty self Also, those who had experienced material compensations as a child showed higher propensity for addictive purchase. Third, the propensity for addictive buying in TV home shopping was higher among those who had higher propensity for materialism, who took a serious view of markers or friends. Those who abuse their credit cards were more likely to have TV home shopping addiction.

This study aims to examine the gender characteristics depending on golfers' criteria of choosing golf-wear and to identify the differences in consumption propensity. The research methodology was through the use of questionnaires, completed by golfers in Gyeongnam. As a result of examining the gender differences in the criteria of choosing golf-wear, it has been found that female golfers give more considerations to suitability to body, care convenience, and functionality than male golfers do when choosing golf-wear. As a result of analyzing the factors regarding the consumption propensity of golf-wear, they are categorized into ostentaion, fashion, aesthetic appreciation and practicality. According to the consumption propensity, male golfers were classified into three groups: ostentatious perfection, practical, common group. Female golfer were classified into three groups: practical, common, ostentatious perfection group. Groups of men golfers showed significant differences in the factors of ostentation, fashion and aesthetic appreciation of the consumption propensity. Groups of women golfers, however, showed significant differences in the factors of ostentation and practicality of the consumption propensity. It is considered that marketers need to develop golf-wear according to the gender characteristics by referring to the fact that choice criteria differ according to gender and consumption propensity.

The propensity score matching method is a statistical method used to reduce selection bias in observational studies and to show effects similar to random allocation. There are many observational studies in dentistry research, and differences in baseline covariates between the control and case groups affect the outcome. In order to reduce the bias due to confounding variables, the propensity scores are used by equating groups based on the baseline covariates. This method is effective, especially when there are many covariates or the sample size is small. In this paper, the propensity score matching method was explained in a simple way with a dental example by using R software. This simulated data were obtained from one of retrospective study. The control group and the case group were matched according to the propensity score and compared before and after treatment. The propensity score matching method could be an alternative to compensate for the disadvantage of the observation study by reducing the bias based on the covariates with the propensity score.

This study attempts to analyze the propensity for conspicuous consumption of the adolescent consumers and related variables such as socio-economic variables, consumer experience, materialism and consumption-oriented attitudes to provide a basis for the development of consumer education program. The survey of this research was conducted by means of self admistered questionnaire with 788 adolescent consumers attending middle and high school located in Ulsan. The results of this research were as follows: 1) The average level of the propensity for conspicuous consumption was a little high median point. This implies that consumer education is necessary for the adolescent consumer in order to reduce the level of conspicuous consumption. 2) The adolescent consumers' propensity for conspicuous consumption varies significantly according to the socio-economic variables such as sex, grade, the allowance interval, the amount of allowance, the mother's education and the subjective level of household consumption. 3) The propensity for conspicuous consumption is positively correlated with materialism and the consumption-oriented attitudes. The consumer experience is positively correlated with materialism and not significantly correlated with the propensity for conspicuous consumption and the consumption-oriented attitudes. Materialism is positively correlated with the consumption-oriented attitudes. 4) According to the results of the regression analysis examining the influences of variables affecting the propensity for conspicuous consumption, the relative importance of the variables are in the order of; materialism, the consumption-oriented attitudes, sex and the amount of allowance. These independent variables explains 49.3% of the total variance about the propensity for conspicuous consumption.

The objective of this study was to find variables related to propensity of compensatory consumption of university students in Korean and Japan. Questionnaires research method was conducted and 477 samples were selected. Korean undergraduates have higher propensity of compensatory consumption for negative feelings than Japan undergraduates. Japan undergraduates have higher propensity of compensatory consumption for positive feelings than Korean undergraduates. Korean undergraduates have a tendency to compensate positive and negative feelings by drinking. Japan undergraduates have a tendency to compensate positive feelings by eating out, and to compensate negative feelings by buying books. In compensatory consumption for positive feelings, Korean undergraduates is influenced by group identity, but Japan undergraduates is influenced by reference group. Propensity of compensatory consumption of Korean undergraduates is mostly influenced by consumption tendency, materialism, group identity, and self-concept. Propensity of compensatory consumption of Japan undergraduates is influenced by consumption tendency, materialism, reference group, and their family income. The strongest predictor of propensity of compensatory consumption of Korean and Japan undergraduates is consumption tendency, followed by materialism.

Causal inference methodologies have been developed for the past decade to estimate the unconfounded effect of an exposure under several key assumptions. These assumptions include, but are not limited to, the stable unit treatment value assumption, the strong ignorability of treatment assignment assumption, and the assumption that propensity scores be bounded away from zero and one (the positivity assumption). Of these assumptions, the first two have received much attention in the literature. Yet the positivity assumption has been recently discussed in only a few papers. Propensity scores of zero or one are indicative of deterministic exposure so that causal effects cannot be defined for these subjects. Therefore, these subjects need to be removed because no comparable comparison groups can be found for such subjects. In this paper, using currently available causal inference methods, we evaluate the effect of arbitrary cutoffs in the distribution of propensity scores and the impact of those decisions on bias and efficiency. We propose a tree-based method that performs well in terms of bias reduction when the definition of positivity is based on a single confounder. This tree-based method can be easily implemented using the statistical software program, R. R code for the studies is available online.

This study conducted to identify the influence of consume propensity on the visiting satisfaction among 253 people who visited the themed restaurants across the country within two months from the date of January 7, 2016. The result of this study are as following: Sociality, impulsivity, and planning are used for estimating the propensity to consume, and sociality (${\beta}=.551$, p<.001), impulsivity (${\beta}=.094$, p<.05), and planning (${\beta}=.328$, p<.001) had the significant positive (+) influence on satisfaction. Second, the choice of the themed restaurant had the significant positive (+) influence on the all variables of consume propensity in the first stage model that the propensity to consume of consumers was considered as an independent variable. In the second stage input model, the choice of restaurant (${\beta}=0.228$, p<.01) had the significant positive influence. That is, the choice of restaurants generally elevated the satisfaction of visiting the themed restaurants. In the third stage that the interaction between the propensity to consume of consumers was considered as an independent variable. The results show there was the significant positive (+) regulation effect with sociality (${\beta}=.108$, p<.05) and planning (${\beta}=.167$, p<.05), but there was no influence with impulsivity.
