This research presents that exogenous characteristics of consumers affect eco-friendly vehicle preference. The car consumers are classifies into two groups by their characteristics - sex, age, and fuel expense. To find differences in the preference for eco-friendly vehicle, marginal utilities and compensate variations of vehicle attributes are estimated. The results suggest that there are significant differences in marginal utilities and compensate variations. However, the compensate variation is more reliable standard to test the preference differences because utility is a subjective measure. Men and old people have stronger preference for the fuel efficiency than women and young people. High fuel expense people have more preference for short time charging vehicles than low fuel expense people. In addition, gasoline vehicles are more attractive to young people than old people.

Korea has been widely recognized as the most successful country for reversal of the rise in sex ratio at birth (from the mid-1980s to the mid-1990s) in a short period of time. However, unusually high sex ratios at birth are still observed in most regions as parity increases. Given that imbalanced sex ratios at high birth orders are mostly due to son-selective abortion, it still remains questionable whether son-selective reproductive behavior has vanished in Korea. The main purpose of this study is to analyze the pattern of changing trends and socioeconomic differentials in sex ratio at birth. Micro-data from birth registration for 2009 are utilized. Attention is focused on analyzing sex ratios at birth in Youngnam region according to age of mother, parity, educational attainment of parents, and occupation of parents. A series of simulations are also conducted in this paper to show how prenatal sex screening and son-selective abortion have affected the level of sex ratio at birth for years 1994, 2005 and 2009.

This study was designed to investigate the role of weight control in the formation of underlying pathology in eating disorder or eating related problems. The subjects were 304 college athletes(Male : 187. Female: 121) and they were divided into two groups according to need for weight control(Weght control group: 110, Weght non control group: 194). The authors used self report questionnaire which was composed of epidemiologic data, food habit scale, eating attitude test, scale for locus of control for weight, scale for food preference and eating behavior. And we also used Eysenck Personality Questionnaire of Korean standardized edition for assessment of personality characteristics, Beck depression inventory, and the scale of hypochondriasis. The results were as follows: 1) Body mass index and the amount of cigarrette smoking and alcohol drinking showed significant differences by sex but not by need for weight control. 2) Eating habit of female athletes was the worst in all athletes. The score of eating attitude test of female athletes was higher than that of male athletes but there was no significant difference by need for weight control. Food preference and eating related behavior was also different by sex. 3) There were no significant differences in all subscales of Eysenck Personality Questionnaire, Beck depression inventory, and the scale of hypochondriasis between two groups which were divided by need for weight control. Neuroticism score was higher in female atheletes and psychoticism score was the highest in weight control male atheletes. 4) There was no significant difference in number of population with abnormal EAT score(to-tal score$\geq$26) between two groups which were divided by need for weight control. 5) The score of eating attitude test had positive correlation with the score of psychoticism and the tendency of depression in weight control male athletes but not in non-weight control male athletes. In non-weight control male athletes, the score of eating attitude test had positive correlation with the score of lie scale. so its correlation is different from those of weight control male athletes. But in female athletes, the score of eating attitude test had significant positive correlation with the score of psychoticism in both groups. In conclusion, these results suggest that the differences of eating traits in athletes are depend upon the sex difference, not upon the need for weight control. and that the role of weight control in eating disorder or abnormal eating attitude differs according to sex.
