A questionnaire on awareness was conducted to examine the attitude toward EBP, the educational experience of EBP, and the performance ability of EBP. A questionnaire consisted of items on the general characteristics, the attitude toward EBP, the educational experience of EBP, and the performance ability of EBP of the subjects. Data analysis was made by IBM SPSS Statistics Ver. 20. The EBP awareness was examined by the independent t-test. Results. For the attitude toward EBP, there was a statistically significant difference in the item of 'Therapists should judge whether they apply study results to individual patient. For the educational experience of EBP, there was no statistically significant difference in all items. For the performance ability of EBP, there was a statistically significant difference in the item about the ability to understand patient's desire for treatment and treatment preference and the item about the ability to determine appropriate treatment process in cooperation with patients.

  • Objectives : We investigated the correlation of the skin color to blood circulation on the face of Korean female by noninvasive-skin measuring devices. Methods : Korean female(37.47${\pm}$3.66 years, n=36) aged 30-45 years were participated in this study. We measured the skin color of the face with Spectrophotometer CM2600d (Minolta, Japan) and the skin blood flow with Laser Doppler Imaging-Periscan PIM II (Perimed AB, Sweden). The skin color and blood circulation of three groups (30-35 years, 36-40 years, 41-45 years) divided on age were analyzed by paired-t test and regression analysis. Results : The L* values of the skin were decreased and the a* values were increased significantly with age. This means that the more age increase, the more the skin is dark and red. But the skin blood flow was not significantly different with age and skin color. Conclusions : In the oriental medicine, It was reported that the face of the female over 35 years is changed gradually haggard and the blood circulation is decreased. In our study, the blood circulation was not changed and the skin color was dark and red with increasing the age. We think this symptom resulted from the better nutrition than the past, the change of the blood-quality and this changes were too sensitive to be measured by Laser Doppler Imaging system.

  • The purpose of this study is to examine residents' perceptions of the outdoor spaces of environmentally-friendly apartment complexes focused on quality of life. On-site intercept surveys were performed to collect data and samples were selected from the residents who are currently living in two different environmentally-friendly certified apartment complexes. This study has examined importance and satisfaction of outdoor spaces of the study sites as they relate to quality of life, as well as they correlation between the New Environmental Paradigm(NEP), and satisfaction and loyalty, respectively. Data were analyzed using several statistical methods including descriptive statistics, Importance-Satisfaction Analysis(ISA), t-test, and correlation. The results suggest that outdoor spaces of the apartment complexes are perceived as an important place to improve residents' quality of life. Residents showed a high satisfaction rate to the natural environmental features(e.g. natural areas present, amenity of space) while they showed a lower satisfaction rate to the social environmental features(e.g. access to public transportation). Although most residents tend to have the New Environmental Paradigm based on the study results, NEP did not influence the level of satisfaction in environmentally-friendly apartment complexes. In contrast, there was a significant relationship between NEP and loyalty. In addition, a strong correlation emerged between satisfaction of outdoor spaces and loyalty to the housing estates. Given these results, various recommendations were given to promote better use of outdoor spaces of dwellings to improve residents' quality of life.

  • The purpose of this study was to analysis the effect of form of outsole on lower leg Electromyography (EMG) during gait. The subject were 11 women(mean age $47.33{\pm}4.4$ years, height $158.00{\pm}3.3$cm, weight $59.50{\pm}6.1$, body mass index $23.80{\pm}1.8kg/m^2$), who had no serious foot musculoskeletal disease within3years prior to study. The vastus medialis, gastrocnemius, semitendinosus, tibialis anterior were compared during gait with 2 types of shoe(complex function double rocker sole, negative-heel rocker sole) by using pair t-test(p<.05). The vastus medialis, gastrocnemius, semitendinosus were not found to be significantly different among the 2 types of shoe but tibialis anterior were found(p<.05). The complex function double rocker sole shoe caused a significant change in energy expenditure compared to the negative-heel rocker sole shoe.

  • The globalization of Korean food has long been an important agenda for both the Korean government and food-related firms, and there have been many trials and errors because of cultural differences in food consumption habits. This study explores Chinese consumers' purchase behaviors toward chicken menus, and for a better understanding of these behaviors, the study considers differences in consumer behavior in between Chinese and Korean consumers around Daejeon, South Korea. The sample included a total of 232 respondents who provided information on their purchase behaviors toward chicken menus. A total of 13 purchasing attributes were compared through a t-test, and according to the results, there were significant differences in 6 attributes: "like the taste" (p<0.001), "as a side dish for drinks" (p<0.001), "to feel good" (p<0.01), "like all chicken dishes" (p<0.05), "for health" (p<0.05), and "low prices" (p<0.05). The results for chicken consumption indicate significant differences in frequency (p<0.05), goals (p<0.01), and expected fair prices (p<0.05). These results suggest that, to make Korean chicken dishes a global Korean menu, future research should focus on consumers' motives for purchasing chicken menus, satisfaction, and characteristics. The generalizability of the results may be limited because the survey was conducted by considering only those students in the Daejeon area. Future research should include a wider range of consumers in both Korea and China for better strategic plans for food-related firms.

The objective of this study was also to provide foundation for appropriate dental hygiene intervention model for scaling. In this study, anxiety reactions were measured among 178 patients, who made appointment with dental hygienists for scaling between May and July, 2009. The analysis was done in SPSS 12.0 statistical program which confirmed Cranach's alpha value. Technical statistics, t-test and One-way ANOVA, correlation and regression were also used. The result of the study is following: While dental hygienist conducts scaling, the dental anxiety was each measured in following categories: Thus male, age between 40 and 50, single, high school graduated and unemployed were measured highest dental anxiety among various groups. Dental Fear Scale demonstrated the validity of relationship between dental anxiety and self efficacy. The correlation was equated as r=-.409(p<0.01). In the other words, the higher self efficacy, the lower dental anxiety. The relationship between dental anxiety and physical and physiological condition was relevant. Physical condition was r=-.229(p<0.01) And then, the psychological condition was r=-.299(p<0.01). Thus, better physical and physiological condition results in less dental anxiety. The relationship between expected Self-efficacy and dental anxiety is also valid. The dental anxiety after performance accomplishment is r=-.239(p<0.01), after vicarious experience is r=-.195(p<0.01), after verbal persuasion is r=-.152(p<0.05), after recognition of physiological state is r=-.410(p<0.01). In conclusion, sex, age, marital status, education level, employment, physical condition, physiological condition are all relevant to dental anxiety(F=8.834). Both independent and dependent variables p<.05 have 37.5% persuasiveness.
