Purpose: The present study investigated nutrient supplement intake to examine the relationship between the health behaviors of nutrient supplement users and nonusers and nutrient supplement users and other drug users. The results provide baseline data to understand whether nutrient supplements actually perform as expected in view of the fact that healthy people that take nutritional supplements may become healthier, but may also develop nutritional supplement abuse problems. Among 7,006 household heads of 24,614 household members from the Korea Health Panel data in 2008, a total of 6,009 household heads were the respondents of the Korea Health Panel Survey (appendix) in 2009. Method: The subjects of the present study were targeted household heads. The respondents who reported that they had taken (planned to take) life/health promotion-related drugs (01. vitamins/nutritional supplements) for more than three months that were purchased at pharmacies during the past one year at the time of the survey were defined as nutritional supplement users. Those who took other drugs (05. hair-loss treatments, 06. obesity treatments, 10. others) were regarded as other drug users. A chi-squared test was performed to analyze the sociodemographic characteristics of the subjects and differences between groups. Multiple regression analyses were conducted to analyze health behaviors according to nutrient supplement intake. Result: Comparison of (A) nutritional supplement users and nonusers revealed that those who were women, 50 years or older, and spent more than average living expenses were more likely to take nutritional supplements, which was not significant in health behavior variables. Analysis of nutritional supplement users and other drug users (B) revealed that those who were high school graduates or above, had a spouse, were non-smokers, took drugs, ate regular meals, and were not stressed by economic or family conflicts were more likely to take nutritional supplements. Conclusion: The results of the present study indicated that people take nutritional supplements because of their psychological desire to be healthy, not because they are not healthy, have problems, or believe supplements will make them healthier.

Despite the fact that understanding customers satisfaction with transportation services is a subject of great importance, authors, so far, found no systematic researches referred to that issue. From this point, studying the satisfaction with subways services can be extremely useful. Empirical study of key factors in the satisfaction with subway services is the departure point, which holds as objectives, and we believe, will contribute to overall increasing in the number of subways services used and in the amount of public benefits derived from that usage. In order to achieve these goals: First, several items referred to some key factors in the satisfaction of subway usage were systemized. Second, a research of specific weights attached to those key factors by subway passengers was conducted. Knowledge of the satisfaction variables system can provide deep insights into ones perceptual experience when using a subway. The results were as follows: Various interrelated factors compose a passengers satisfaction with subway services. People do not just use subway passively; a number of key factors, like physical and personal services, exact timing, easiness to access etc. determine the passengers satisfaction with subway. In order to find out specific weights of these key factors multiple regression analysis was employed. Results showed that satisfaction with subway is determined by (in order of importance) easiness to access, quality of physical services, friendliness of working stuff and timing exactness. According to the findings, passengers do not use subway as a simple mean of transportation, rather they perceive it as a complex combination of environmental elements and overall satisfaction depends on these various factors. Therefore, to learn passengers satisfaction with subways services, passengers subway experience must be thoroughly studied and analyzed, and this is where papers value resides.
