This study attempted to determine differences between the perceived empowerment level and job satisfaction depending on hairdressers' demographic characteristics and analyze the effects of their empowerment on job satisfaction. For this, a total of 310 hairdressers in Gwangju-Jeonnam and Seoul-Gyeonggi-do were chosen through convenience sampling, and then a questionnaire survey was conducted. The valid 277 copies were used for final analysis. For data analysis, descriptive statistics, factor analysis, reliability analysis, t-test, ANOVA, Duncan's test, and multiple regression analysis were conducted using SPSS 15.0. The study results found the following: First, in terms of the subordinate factors of empowerment, the following four factors were found: meaningfulness, self-determination, competence, and impact. Second, depending on demographic characteristics (e.g., age, career, type of beauty salon, job title, punch-in time, monthly pay), a statistically significant difference was found between empowerment and job satisfaction (p<.01). Third, hairdressers' perceived empowerment level had a positive impact on job satisfaction (p<.01). In terms of the empowerment on job satisfaction by sub-factor, 'self-determination' was largest, followed by 'meaningfulness' and 'competence.' Therefore, beauty salon owners need to manage their business more efficiently by converging cosmetology and business management by expanding empowerment among hairdressers properly after recognizing the importance of hairdresser empowerment.

This study was performed to the possibility of developing anti-aging convenient food that is to Koreans' taste. Editor: this abstract appears to describe a study of public opinion and not related to the development of anti-aging convenient foods. In total, The 150 adults, living in Seoul (Korea), participated in this study in the capacity of subjects. Editor: You really have to mention the age-range of the subjects, as senility is an old age disease. In particular, you talk about the intention of subjects (discussed below) to buy anti-aging food products. This would be directly related to their age, as I assume that older people would be more concerned about senility that relatively younger subjects. They were randomly assigned to 25 groups. In result initial descriptive analysis revealed that, 82 percent of subjects awoke to were aware of senility, and the while 26.7 percent were seriously thought of it concerned. Furthermore, The 58.7 percent said that believed food has the possibility has a role in of controlling senility, and the while 64.0 percent said stated that senility may be controlled by eating constitutional foods. Further comparative analysis of In the case of the group of which members subjects have been who were trying to control senility revealed that their, the reliance on food general and constitutional food was significantly higher than those who have not tried to do so did nothing. The From the 61.3 percent have been of subject who were trying to control senility, from among them, the 74.0 percent and the 22.7 percent were relied on physical taking exercises and anti-aging foods, respectively. Likewise, it was ascertained When asked whether subjects intend to purchase anti-aging convenient food if it was is developed. The 67.3 percent and the 72.7 percent indicated their intentionded to purchase the normal product and constitutional products, respectively. Resultantly, anti-aging convenient food was in demand to some extent. Given that anti-aging products are in high demand, In such a case, senile severity (p<0.05), anti-aging possibility in constitutional foods (p<0.001) and anti-aging action (p<0.001) are regarded as variables in the purchase of the normal products. In the case of relation to constitutional products, anti-aging possibility in constitutional food (p<0.001) and anti-aging action (p<0.001) were regarded as variables.

This study is aimed to evaluate the effects of a synthetic MR technique in reducing metal artifacts. In the experiment, the in-plane and through-plane images were acquired by applying a synthetic MR technique and a high-speed spin echo technique to a phantom manufactured with screw for spinal surgery. The area of the metal artifact was compared. The metal artifacts were measured by dividing the signal-loss and the signal pile-up areas, and the area of the final artifact was calculated through the sum of the two. As a result, the metal artifacts were relatively reduced when the synthetic MR techniques were applied to both in-plane and through-plane. Comparing by sequence, the in-plane T1 images decreased by 23.45%, T2 images by 20.85%, PD images by 19.67%, and FLAIR images by 22.12%. Also, in the case of the through-plane, the T1 image decreased by 62.95%, the T2 image decreased by 73.93%, the PD image decreased by 74.68%, and the FLAIR image decreased by 66.43%. The cause of this result is that when the synthetic MR technique is applied, the distortion is due to the signal pile-up and does not occur and the size of the entire metal artifact is reduced. Therefore, synthetic MR technique can very effectively reduce metal artifacts, which can help to increase the diagnostic value of images.
