Recently, dating violence has emerged as a serious social problem, but there is not enough research on controlling behavior among the subtypes of dating violence. Thise study explored the relationship between psychological entitlement and controlling behavior, and the mediation effect of social dominance orientation and social comparison orientation. Furthermore, the study examined if the mediation effect of social dominance orientation between psychological entitlement and controlling behavior differed by gender. As a result, the higher the level of psychological entitlement, the stronger the level of social dominance orientation, social comparison orientation, and the controlling behavior. In addition, the stronger the level of social dominance orientation and social comparison orientation, the more frequently was the occurance of the controlling behavior committed. The level of social dominance orientation mediated the relationship between psychological entitlement and controlling behavior. The level of ability comparison orientation mediated the relationship between psychological entitlement and controlling behavior. The mediation effect of social dominance orientation between psychological entitlement and controlling behavior was moderated by gender. In other words, the mediation effect of social dominance orientation between psychological entitlement and controlling behavior was significant for the male, but not for the female. The limitations of the study and suggestions for further research were discussed.

It is known that one out of every ten people walking down the street is left-handed. In daily living, left-handed people come across hardwares and facilities that were designed for right-handed people. Most tools, utensils, office equipment, home appliances, clothes, medical instruments, sporting goods, weapons, and public facilities are made for the right-handed person. Many left-handed people thus have trouble with living in our environments. In this study, 1,933 Korean male and female subjects aging from 10 to 82 were selected to investigate the various statistics about hand dominance and their employment characteristics of preferred hand in handling diverse products and facilities. The statistics showed that 5.6% were left-handed and 7.6% were ambidexter. There were strong tendency that left-handed people use more left hand when take action that force is required than when take exquisite action. Ambidexter and right-handed people use more right hand when they take exquisite action is required than when take action that force is required. It was found from these results that people use their hands differently depending on the hand dominance when they handle things, hence this should be considered in designing hand control devices.

The purpose of this study was to investigate the effect of adolescents' need on their attitudes to aesthetic surgery and clothing. Subjects were 627 middle and high school students. In this statistical analysis, SPSS 10.0 for Windows Program was used to calculate percentage, mean, and standard deviation. Also, these data were verified by Factor analysis, t-test, One-way Anova, Duncan' multiple range, Pearson's correlation coefficient, and Multiple Regression Analysis. The results of this research were as follows: Adolescents with higher need for achievement showed negative attitudes toward the secret and risk of aesthetic surgery. On the other hand, those with higher need for dominance and exhibition were in favor of the surgery and willing to have it despite its high cost and risk. Individuality of clothing was directly affected by need for achievement and dominance. Adolescents with higher need for achievement and dominance considered individuality as one of the most important factors. And sexual attractiveness of clothing had a positive correlation with both need for dominance and exhibition. Such a fact leaded that adolescents with higher need for dominance and exhibition considered sexual attractiveness as one of the most important factors, along with individuality. As a conclusion, adolescents' need play an important role in explaining the recently observed trends among adolescents in aesthetic surgery attitude and clothing attitude.

Purpose According to a recent survey, more than 90% of customers make purchase or use decisions for their products and services, primarily based on word-of-mouth(WOM) information (reviews, recommendations, ratings, etc.). However, few studies have explored what factors influence user's WOM intention in the context of OTT service. To address this gap, this study investigates the antecedent factors of WOM intention by adopting stimulus-organism-response (SOR) theory and pleasure arousal dominance (PAD) theory as a theoretical basis. Design/methodology/approach The research model consists of stimulus factors (diversity of original content, aesthetics, interactivity, personalization quality), emotional factors (pleasure, excitement, dominance), and behavioral factor (WOM intention). The research hypothesis was tested using the survey data collected from OTT service users of 305. Findings The result reveals that diversity of original content significantly affects on pleasure and arousal whereas it is not associated with dominance. Findings indicate that aesthetics positively influences pleasure, and interactivity is not associated with arousal. It is also proven that personalization quality has a positive effect on dominance. In addition, pleasure, arousal, and domination are proven to be positively and significantly related to WOM intention.

There was no a difference of genetic analysis among methods(means, joint scaling test, 3 Parameter model) . The magnitude of additive effects generally paralleled the magnitude of difference between parental means and appeared to be more independent from non-allelic interaction than did dominance effects, whereas the magnitude of dominance effects were inflated by non-allelic interaction. Additive effects were significant for all characteristics observed and it was a major effects in inheritance of number of leaves. Dominance effects were higher than additive effects for plant height, days to flower, flesh leaf weight per plant, curing rate, total alkaloid and total nitrogen.

Unlike the mean-variance approach, the stochastic dominance approach is to form a portfolio that stochastically dominates a predetermined benchmark portfolio such as KOSPI. This study is to search a set of portfolio weights for the first degree stochastic dominance with maximum expected return by managing the constraint set and the objective function separately. An algorithm was developed and tested with promising results against Korean stock market data sets.

Unlike the mean-variance approach, the stochastic dominance approach Is to form a portfolio that first-degree stochastically dominates a predetermined benchmark portfolio, e.g. KOSPI. Analytically defining the first derivative of the objective function, an optimal algorithm of nonlinear programming was developed to search a set of optimal weights systematically and tested with promising results against veal data sets from Korean stock market.

In multiattribute decision making a decision maker (DM) can choose the best alternative if his/her multiattribute utility function and the joint probability distribution of outcomes are exactly known. This paper develops multiattribute stochastic-statistical dominance rules which can be applied to the situation when neither of them is known exactly, that is, when the DM cannot calculate the expected utility for each alternative. First, the notion of relative risk aversion is used dominance rules are developed to screen out dominated alternatives so that hi/she choose the best one among the remaining nondominated alternatives.

The stochastic dominance approach is to form a portfolio that stochastically dominates a predetermined benchmark portfolio such as KOSPI. This study is to search a set of portfolio weights for the first-order stochastic dominance with maximum utility defined in terms of mean and variance by managing the constraint set and the objective function in an iterative manner. A nonlinear programming algorithm was developed and tested with promising results against Korean stock market data sets.

Radicoid structure of herbaceous communities in Mt. Kumbyung, Chunchon, Kangwon-Do was clarified emphasizing on the dominance of clonal plants in relation to vegetation development. In the total vegetation, 46% species identified were rhizomatous, 26% were species with tap roots, and 13% were stoloniferous species. Thus, all clonal species, including plants with bulb, corm and tuber, covered 62.8% of the total species. in the understory of Quercus, Pinus and Larix forests, 68.2% were clonal, which means 5% more compare to total vegetaion. Dominance of clonal plants became more conspicuous as their importance value was calculated. That is, they covered average 86% for the following three communities: 85% in Quercus, 95% in Pinus, and 76% in Larix, Especially, the rhizomatous plants were remarkable. Overall, clonal species dominated over the other radicoid types in terms of not only the number of species, but also the importance value. Dominance of these species was more peculiar in understory of forests, indicating the occupancy of clonal plants was related to the vegetation development.
