Background No head to head comparison is available between surgical lip lifting and upper lip filler injections to decide which technique yields the best results in patients. Despite the growing popularity of upper lip augmentation, its effect on societal perceptions of attractiveness, successfulness and overall health in woman is unknown. Methods Blinded casual observers viewed three versions of independent images of 15 unique patient lower faces for a total of 45 images. Observers rated the attractiveness, perceived success, and perceived overall health for each patient image. Facial perception questions were answered on a visual analog scale from 0 to 100, where higher scores corresponded to more positive responses. Results Two hundred and seventeen random observers with an average age of 47 years (standard deviation, 15.9) rated the images. The majority of observers were females (n=183, 84%) of white race (n=174, 80%) and had at least some college education (n=202, 93%). The marginal mean score for perceived attractiveness from the natural condition was 1.5 points (95% confidence interval [CI], 0.9-2.18) higher than perceived attractiveness from the simulated upper lip filler injection condition, and 2.6 points higher (95% CI, 1.95-3.24) than the simulated upper lip lift condition. There was a moderate to strong correlation between the scores of the same observer. Conclusions Simulated upper lip augmentation is amenable to social perception analysis. Scores of the same observer for attractiveness, successfulness, and overall health are strongly correlated. Overall, the natural condition had the highest scores in all categories, followed by simulated upper lip filler, and lastly simulated upper lip lift.

The present study was conducted with the aim to investigate the ameliorative effects of a new soybean product (cheonggukjang) fermented with Bacillus amyloliquefaciens SCGB1 (SFBA) in atopic dermatitis (AD) mouse model. Visual evaluation of AD induction in the mice indicated the remarkable control of SFBA in reducing the pathological severity of AD-like skin lesions reported as the SCORAD score of AD clinical symptoms. The results revealed that SFBA reduced dorsal skin and epidermal thickness to a similar extent with prednisolone. Further analysis revealed the dominance of SFBA in restraining mast cell infiltration in the dermis; immunoglobulin-E expression in serum; and TH2 IL-4 cytokine and itch-related IL-31 cytokine in the mice skin and serum. SFBA also suppressed scratching behaviours in mice induced by compound 48/80. Further histological findings also revealed the alleviation of collagen fiber deposition in dermal skin of the AD mice model. These actions of SFBA were examined to be mediated by its suppression of the phosphorylation activation of key signalling molecules such as $NF-{\kappa}B$ and MAPK responsible for the induction of cytokine production. Thus, SFBA can be considered as a promising functional food for managing clinical, histological and immunological spectra associated with AD.

This study adopts 'intersectionality' as a key concept of Sheila Levrant de Bretteville's design works. As a method of research, this research suggests the definition of intersectionality, from the idea of black feminism. Analysis of the features are such as 1) Typography of speech, 2) Collection of narrative, and 3) site specific installation. The inclusion of the various situations of the individuals reflected in the design throughout de Bretteville's works has made it possible to guarantee the intersectionality. De Bretteville overthrows the context of the power in which the design is placed, embracing forgotten or less illuminated positions. As a result, this research could derive three implications such as 1) visualization of invisibility, 2) subjectification of object, and 3) demarginalization of marginality. The perspective of the intersectionality are in line with the values of contemporary Korean society and might be an insight for researchers who want to establish a design philosophy.

Objectives To observe the pain reduction effect of Korean medical treatment combined with supine JS cervical therapy on neck pain and headache caused by whiplash injury. Methods The medical records of 30 patients suffering from neck pain and headache caused by traffic accidents from August 1, 2020 to October 30, 2020 were studied. 15 patients receiving supine JS cervical therapy combined with Korean medical treatment were assigned to group A and another 15 patients receiving Korean medical treatment but without Chuna therapy were assigned to group B. The following patient data were analyzed retrospectively - age, sex, and number of admission days, neck pain and headache visual analogue scale (VAS), and neck disability index (NDI). Statistical analysis was conducted using IBM SPSS 25.0. for Windows. A p-value≤0.05 was considered to be statistically significant. Results Both neck pain and headache VAS score in group A and B showed a statistically significant decrease. The changes in neck pain and headache VAS score in group A was statistically significant higher compared to those of group B. NDI in group A showed a statistically significant decrease, but NDI in group B did not decreased statistically significant. Conclusions Korean medicine treatment effectively reduces neck pain and headache. Especially, the pain reduction effect is better in patients receiving Korean medicine treatment combined with supine JS cervical therapy than in those receiving Korean medicine treatment without supine JS cervical therapy.

Objectives To determine the evidence of effectiveness and safety of extracorporeal shock wave therapy (ESWT) with meridian and acupoint theory for knee osteoarthritis. Methods By March 3, 2021, five foreign electronic databases and six Korean medical electronic databases were reviewed with the key words 'extracorporeal shock wave' and '(acupoint OR acupuncture point)'. This key words was set up to increase the sensitivity of the search. After the search, knee osteoarthritis study was selected based on the title and abstract and then included after full-texts were read. Results Five randomized controlled trials were eligible in our inclusion criteria. The meta-analysis of three studies showed positive results for the using ESWT with meridian and acupoint theory for knee osteoarthritis compared with the control group on efficancy rate, visual analog scale and lysholm knee score. but there remains a conundrum regarding the safety of ESWT in the treatment of knee osteoarthritis. Conclusions Most of studies showed ESWT with meridian and acupoint theory were statistically effective to knee osteoarthritis. However there are limitations that the number of selected studies was small, risk of bias was unclear. So use of ESWT with meridian and acupoint theory for knee arthritis has limited evidence compared to usual care.

The gas-liquid counter-current flow limitation (CCFL) is closely related to efficient and safety operation of many equipment in industrial cycle. Air-water countercurrent flow experiments were performed in a tube with diameter of 25 mm to understand the triggering mechanism of CCFL. A parallel electrode probe was utilized to measure film thickness whereby the time domain and frequency domain characteristics of liquid film was obtained. The amplitude of the interface wave is small at low liquid flow rate while it becomes large at high liquid flow rate after being disturbed by the airflow. The spectral characteristic curve shows a peak-shaped distribution. The crest exists between 0 and 10 Hz and the amplitude decreases with the frequency increase. The analysis of visual observation and characteristic of film thickness indicate that two flooding mechanisms were identified at low and high liquid flow rate, respectively. At low liquid flow rate, the interfacial waves upward propagation is responsible for the formation of CCFL onset. While flooding at high liquid flow rate takes place as a direct consequence of the liquid bridging in tube due to the turbulent flow pattern. Moreover, it is believed that there is a transition region between the low and high liquid flow rate.

In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.

Background: To determine the benefit of pelvic floor muscle exercise (PFME) with visual biofeedback on promoting patient recovery from incontinence, we investigated variables associated with the early restoration of continence for patients who underwent robot-assisted radical prostatectomy (RARP). Methods: Of the 83 patients enrolled, 41 consecutive patients completed PFME (the exercise group), and the other 42 consecutive patients just before the PFME program commenced (the control group). The primary outcome was whether PFME engagement was associated with zero pad continence restoration within 3 months of surgery. Results: Continence restoration percentages (defined as zero pads used per day) at 1, 3, and 6 months after surgery were 49.4%, 77.1%, and 94.0%, respectively. The exercise group achieved significantly higher recovery rates at 1 month (p=0.037), 3 months (p<0.001), and 6 months (p=023). Cox regression analysis demonstrated that a lower Gleason score (<8; hazard ratio [HR], 2.167), lower prostate specific antigen (<20 ng/dL; HR, 2.909), and engagement in PFME (HR, 3.731) were independent predictors of early recovery from postprostatectomy incontinence. Stratification by age showed that those younger than 65 years did not benefit significantly from exercise (log-rank test, p=0.08), but that their elderly counterparts, aged 65-70 years (p=0.007) and >70 years old (p=0.002) benefited significantly. Conclusion: This study suggests that postoperative engagement in PFME with biofeedback speeds up the recovery of continence in elderly patients (≥65 years old) that undergo RARP.

Purpose : To compare the immediate effects of air stacking maneuver using resuscitator bags and balloons. Methods : Twenty healthy young adults participated in this study. Forced vital capacity (FVC) and peak cough flow (PCF) tests were performed at pre-intervention, and then, the maximum insufflation capacity (MIC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow (PEF), and peak cough flow (PCF) were measured using the air stacking maneuver via resuscitator bags and balloons. Interventions were randomly performed, and a 40-min break was provided between interventions. The evaluation process in this study was conducted in accordance with the guidelines of the American Thoracic Society (ATS) 2019. To compare the three outcomes measured at pre-and post-interventions, repeated measures analysis of variance was performed. Results : A significant difference was found in the MIC, FEV1, PEF, and PCF after the air stacking maneuver using resuscitator bags and balloons, whereas no significant difference was observed between resuscitator bags and balloons. Conclusion : No significant difference was found in the immediate effect of the air stacking maneuver using resuscitator bags and balloons in this study. Air stacking maneuver using balloons can increase the success rate of the techniques by providing visual feedback on the amount of air insufflation when performed with balloon blowing exercise. Balloons are cheaper and easier to buy compared to manual resuscitator bags; therefore, education on the air stacking maneuver using balloons will have a positive effect on pulmonary rehabilitation.

This study investigates the waiting and resting behaviors of children within a restorative healthcare facility design. In particular, the aim is to compare children with and without disabilities and reveal similarities and differences in terms of their behavioral characteristics and uses of design facilities, related to positive distraction, for restoration in the hospital. Three major common spaces for outpatients in S children's hospital in Seoul were examined including the main lobby and two waiting and resting spaces in the pediatric and rehabilitation medicine departments, respectively. A total of 155 children under the age of 12-67 with physical disabilities and 88 without-were observed while they waited and rested at the three spaces before or after doctors' examination. Basic demographic information and waiting and resting behavioral characteristics were compared between the two groups. The results indicated that the disabled children were more restricted in terms of space, facilities used, and social behaviors. However, regardless of disabilities, the children showed more positive distractions related to cognitive and social behaviors in areas where restorative design elements such as an aquarium, garden, or visual images were available. Based on the results, design implications were discussed to strengthen positive distraction behaviors in children with and without disabilities and to foster the restorative quality of the spaces for waiting and resting in the children's hospital.
