  • The purpose of this study is to investigate the effect and potential problem of before and after technique in cosmetic surgery advertisements. This study would draw the positive and negative aspects in executing before and after technique by segmenting the surgical part(eyes, nose, and breast). And this study compared before and after technique with after technique and doctor(expert) endorser. Independent variables of this study are advertisement technique(before and after/after/doctor) and the kind of surgery(double eyelid surgery/ rhinoplasty/mastoplasty). Dependent variables of this study are general attitude toward advertising, hospital believability, ethical judgement toward advertising, intention to cosmetic surgery. This study is run as $3{\times}3$factorial design with 30 subjects per cell, resulting in a total sample size of 270. The result of this study shows that advertising technique in cosmetic surgery advertisement important variable to mediate the effect. This study found that before and after technique was more effective than any other techniques. Also, this study found that the kind of surgery variable should be considered in the execution of cosmetic surgery advertisement. Therefore, the result suggests that the kind of surgery and advertisement technique should be spontaneously considered by cosmetic surgery clinic and advertising regulation organizations for the effective communication way and consumer protection.

  • Objective : Skin barrier protects skin against harmful environment. Its function includes antimicrobial barrier as well as physical barrier. But there are few studies about the factors which improve skin barrier recovery after injury. The aim of this study is to investigate the factors which improve skin barrier recovery. Method : Nine hairless mice was anesthetized by inhalation and we tape stripped them. We used thermometer to know temperature one day ago, before anesthesia, before tape stripping, and after tape stripping. Vapometer was used to know transepidermal water loss before tape stripping, after tape stripping. And we used doppler flowmeter to measure blood flow before tape stripping, after tape stripping. Result : After analyzed data, we concluded that temperature was lower after anesthesia than before anesthesia and after tape stripping than before tape stripping. We could know that transepidermal water loss was lower after tape stripping than before tape stripping and more blood flowed after tape stripping. Conclusion : In our study, it was observed that temperature, transepidermal water loss, blood flow changed after tape stripping. But we thought lowered temperature was pathologic situation, more blood flow was to recover after injury. In traditional korean medicine, cold(寒) and imbalance of blood flow(血行) don't only make many skin diseases, but cold(寒) also obstructs blood flow. So we need to study how to warm cold(寒) and improve blood flow.

  • Purpose - This study analyzed the effect of the Trump Government's protectionist trade policies on foreign ownership. Specifically, this study empirically analyzes the hypothesis that foreign ownership will decrease after the Trump Government rather than before the Trump Government. Design/methodology - The hypothesis of this study is based on the expectation that US protection trade policy will negatively affect the profitability of Korean companies. The dependent variable in this study is the foreign ownership ratio, and the independent variable is a dummy variable representing before and after the Trump Government. Multiple regression analysis was performed, including the control variables suggested in previous studies related to foreign ownership. Findings - As a result, foreign ownership increased after the Trump Government rather than before the Trump Government. This study further analyzes whether the main variables affecting foreign investor's decision-making are differences before and after Trump Government. The export ratio, profitability and dividends did not differ before and after Trump Government. However, the level of information asymmetry decreased after the Trump Government than before the Trump Government. This suggests that US protection trade policies do not adversely affect the profitability of Korean companies. However, Korean firms are improving their information environment because US protectionist trade policies can lower profitability and negatively impact capital raising. In this regard, the foreign ownership ratio seems to differ before and after the Trump Government. Originality/value - This study contributes in that it presents data that US protectionist policies can affect Korean corporate governance. This study has implications from the short-term analysis of US protection trade policy.

  • The masticatory function of tooth is maintained by the periodontal health, and periodontal health is also maintained by the masticatory function. Bite forces are withstanded by the PDL, and this thought to be through the viscoelastic theory. Mobility test and Bite force test are used to evaluate the viscoelastic theory of the PDL. In this study, the bite force test was used. In the same conditions of quantity of the supporting tissue, the maximum bite force according to the quality of the supporting tissue was evaluated. The study was conducted on 40 patients with moderate adult periodontitis, who were indications to the modified widman flap treatment. The maximum bite force in the premolar and molar regions were tested before treatment, 3weeks and 4 weeks after treatment. and the results were as follows. 1. In the premolar region, 3 weeks and 4 weeks after treatment showed higher maximum bite force than before treatment. And in the molar region the maximum bite force decreased 3 weeks after treatment, but increased after 4 weeks, compared to before treatment. 2. In the 1st premolar, there were only significant difference between before and 3 weeks after treatment, and between and 4 weeks after treatment. 3. In the 2nd premolar, there were only significant difference between before and 3 weeks after treatment, and between and 4 weeks after treatment. 4. In the 1st molar, there were no significant difference between before, 3 weeks after treatment, 4 weeks after treatment. 5. In the 2nd molar, there were no significant difference between before, 3 weeks after treatment, 4 weeks after treatment. From the results above, it shows that there were improvements in the maximum bite force through specific periodontal treatments, and thus it can be considered in clinical situations, that selection of the prosthodontic material, decisions of extraction, evaluation of the prognosis after periodontal treatment is a helpful method.

  • The purpose of this study is the structural relations will be examined among the VMD image of clothe stores, emotional reactions of brand awareness, brand image, brand attitude, and purchase intention. An empirical study in experimental design was conducted to female college students in their twenties, who made a huge influential group in the fashion industry, by considering the VMD characteristics of clothing shops. It measured the effects of VMD based on the changes to the consumer attitude before and after the VMD renewals, the correlations between brand recognition and VMD, and the influences of VMD on brand recognition and image, which were considered as important factors in creating brand assets. The research findings were as follows: 1. There were differences in emotional reactions according to the VMD image changes before and after renewal. Considering that the consumers recognized the VMD changes before and after renewal and showed different emotional reactions, the VMD image seems to be a major variable affecting their emotions. 2. As for the changes to the VMD image and brand image before and after renewal, the consumers recognized the VMD changes before and after renewal and consequently recognized the brad images differently, which implies that brand image can vary according to the effects of VMD renewal and changes to the VMD image.

  • Purpose: The aim of this study was to determine the change of static and dynamic foot pressure on trunk stabilization exercise in children with spastic diplegic cerebral palsy. Methods: This study examined five male children participants ages 10~14 years old with spastic diplegic cerebral palsy. All subjects participated in a 6-week sling exercise program for trunk stabilization; the exercise was performed three times per week and each session lasted 50 minutes. The subjects were measured for static and dynamic foot pressure and bilateral symmetry of both feet before and after the trunk stabilization exercise. Results: The static foot pressure increased significantly before and after the trunk stabilization exercise (left foot: before $0.41{\pm}0.02%BW/cm^2$ after $0.79{\pm}0.02%BW/cm^2$, right foot: before $0.14{\pm}0.03%BW/cm^2$, after $0.43{\pm}0.44%BW/cm^2$) (p<0.05) and bilateral symmetry of both feet increased (before $0.27{\pm}0.18%BW/cm^2$, after $0.37{\pm}0.05%BW/cm^2$) with more weight shift on left foot than right foot, but was not statistically significant (p>0.05). The dynamic foot pressure increased (left foot: before $2.58{\pm}0.44%BW/cm^2$, after $3.40{\pm}0.31%BW/cm^2$, right foot: before $2.75{\pm}0.19%BW/cm^2$, after $3.26{\pm}0.18%BW/cm^2$) with more weight shift on right foot than left foot, but was not statistically significant (p>0.05), and bilateral symmetry of both feet decreased (before $0.31{\pm}0.36%BW/cm^2$, after $0.13{\pm}0.20%BW/cm^2$) (p<0.05). Conclusion: The findings of this study indicated that the trunk stabilization exercise has a positive impact on static and dynamic foot pressure in children with spastic diplegic cerebral palsy.
