Objective : The goal of this study was to compare several parameters, including wall shear stress (WSS) and flow pattern, between unruptured and ruptured anterior communicating artery (ACoA) aneurysms using patient-specific aneurysm geometry. Methods : In total, 18 unruptured and 24 ruptured aneurysms were analyzed using computational fluid dynamics (CFD) models. Minimal, average, and maximal wall shear stress were calculated based on CFD simulations. Aneurysm height, ostium diameter, aspect ratio, and area of aneurysm were measured. Aneurysms were classified according to flow complexity (simple or complex) and inflow jet (concentrated or diffused). Statistical analyses were performed to ascertain differences between the aneurysm groups. Results : Average wall shear stress of the ruptured group was greater than that of the unruptured group (9.42% for aneurysm and 10.38% for ostium). The average area of ruptured aneurysms was 31.22% larger than unruptured aneurysms. Simple flow was observed in 14 of 18 (78%) unruptured aneurysms, while all ruptured aneurysms had complex flow (p<0.001). Ruptured aneurysms were more likely to have a concentrated inflow jet (63%), while unruptured aneurysms predominantly had a diffused inflow jet (83%, p=0.004). Conclusion : Ruptured aneurysms tended to have a larger geometric size and greater WSS compared to unruptured aneurysms, but the difference was not statistically significant. Flow complexity and inflow jet were significantly different between unruptured and ruptured ACoA aneurysms.

Purpose: The purpose of this study is to examine the effects of clinical art therapy programs utilized at schools on adolescents' suicidal thoughts and stress relief and to validate their effectiveness as a type of adolescent suicide prevention program. Methods: 12 sessions of clinical art therapy for youth suicide prevention were provided, once a week for 90 minutes, for 20 students at five middle schools in Seoul who were at high risk of committing suicide. By using the paired sample t-test, the study presented qualitative data on the analysis of pre- and post- questionnaires and on the subjects' EEG test and saliva test. Results: First, through the clinical art therapy program, the subjects' happiness index improved significantly while their scores of depression and suicidal ideation (suicidal thoughts) decreased. Second, in the EEG and saliva test conducted after the art therapy sessions, emotional stability increased and stress was reduced significantly. Third, according to the results of pre- and post- K-HTP tests and individual activities, the subjects started to recognize the seriousness of suicide and show emotional stability and positive changes in overall attitudes, valuing the rights and life of their own 'precious selves' (self respect). Conclusion: The results of this study indicate that the clinical art therapy program is significantly effective at preventing suicidal ideation by reducing suicidal impulses and depression, by increasing the happiness index, which can serve as a protective factor against suicide, and by increasing emotional stability while reducing stress. Based on the results, there is a need to develop policy measures regarding art therapy programs which can be utilized at schools.

We investigated the work-life balance of clinical professors in charge of patient care, research, and education at medical schools and the demand for work-life balance support according to position (professor, associate professor, or assistant professor). In total, 163 clinical professors completed the consent form and participated in the study. They filled out an online survey consisting of questions about essential characteristics, a work-life balance test, stress, burnout, work-life satisfaction, and work-life balance support needs. We analyzed the results by analysis of variance and cross-tabulation using IBM SPSS ver. 23.0. Differences were found in work-life balance, stress, burnout, and satisfaction with life and work by position. The requirements for support for work-life balance also varied by professional status. Professors had a higher balance between life and work than associate professors or assistant professors. The specific requirements for work-life balance support were also slightly different for each position. Overall, there was a high demand for work process simplification and efficiency for work support, flexible working hours and sabbatical years for family and leisure, and career management consulting and training support for growth. Assistant professors and associate professors had a lower level of work-life balance than professors, as well as higher levels of stress and burnout. Professors' job satisfaction was also higher than that of the other groups. Based on the results of this study, we hope that a healthy work environment can be established through work-life balance support suitable for clinical professors' positions.

Department of radiology implements the hospital-based clinical training to accept medical treatment techniques and to adapt experiences for students. However, it might cause negative effects to training education, leading to doubt about major and pressure about training as lots of students experience clinical treatment and complex stress in unfamiliar environment. Regarding this, pressure element that students can experience and diverse variables of training were compared and analyzed. With students in department of radiology for 6 colleges and universities, from September 15th to October 25th in 2011. The degree of stress for students in training was shown high in the fields of cost(3.06) and trainers(3.02). Value and ideal(2.94), role and experiment(2.93), training environment(2.74) and relationships among trainees(2.64) were followed in the order. Except expense regarding stress from clinical training, but in all factors, women showed higher pressure level than men(P<.05) and in stress range according to BEPSI-K, a meaningful difference was shown in fields of training environment, relationships among trainees and role and experiment(P<.01, P<.001, P<.05). Therefore, It has been confirmed that there is correlation between stress of students and satisfaction for clinical training with each other closely.

Application of ceramic materials for fabrication of dental restoration materials has been a focus of interest in the field of esthetic dentistry. The ceramic materials of choice are glass ceramics, spinel, alumina, and zirconia. The development of yttrium tetragonal zirconia polycrystal (YTZP)-based systems is a recent addition to all-ceramic systems that have high strength and are used for crowns and fixed partial dentures. Computer-aided design/computer-aided manufacturing (CAD/CAM)-produced, YTZP-based systems are popular with respect to their esthetic appeal for use in stress-bearing regions. The highly esthetic nature of zirconia and its superior physical properties and biocompatibility have enabled the development of restorative systems that meet the demands of today's patients. Many in vitro trials have been performed on the use of zirconia; however, relatively fewer long-term clinical studies have been published on this subject. The use of zirconia frameworks for long-span fixed partial dentures is currently being evaluated; in the future, more in vivo research and long-term clinical studies are required to provide scientific evidence for drawing solid guidelines. Further clinical and in vitro studies are required to obtain data regarding the long-term clinical use of zirconia-based restorations.

Objectives: The purpose of this study was to suggest the clinical characteristics and risk factors of facial palsy from the perspective of Korean Medicine. Methods: Medical records of 856 patients, who visited the Korean Medicine hospital with facial palsy from 2004 to 2019, were retrospectively analyzed. The clinical characteristics of facial palsy were suggested by figuring out the distribution of age, sex, occupation, onset season, obesity, modes, signs, symptoms, past and family history. Results: By gender, there were more males (54.6%), and the most common age groups were in their 50s (27.4%) and 40s (23.6%). As for the occupation, unemployed (27.7%) and service and sales workers (14.6%) were the most common, and the onset season was the most common in winter (28.9%). The most common clinical characteristics were overwork (33.0%), mental stress (24.8%), and exposure to cold (19.3%) in modes, 'none' (64.3%), postauricular pain (33.2%) in signs, postauricular pain (26.9%), parageusia (14.8%) in symptoms. Hypertension and diabetes were the most common in both past and family history. In particular, the obesity rate of the subjects (59.8%) was much higher than that of Koreans (32.8%). Conclusions: Based on the historical Korean Medicine literature and the results of this study, it is suggested that overwork, stress, exposure to cold, and obesity are identified as risk factors for facial palsy. Furthermore, dysfunction of the stomach meridian is thought to contribute to the cause of facial palsy.

Composite resin restorations in posterior teeth are increasing due to the aesthetic needs of patients and the development of materials. This trend will accelerate in line with domestic insurance policies. However, resin composites generate stresses due to their contraction during the polymerization process. To reduce the polymerization shrinkage stress of resin composites, incremental layering technique has been recommended for decades. This technique reduces stress at the cavity wall interface and allows a more efficient light curing of the material. Bulk-fill resin composites have been designed to simplify the restorative technique because they can be placed into cavities in a single increment of 4-5mm. The simplification of the operative procedures is desirable in clinical daily practice. In this context, bulk-fill resin composites are an attractive alternative for posterior restorations. However, a clearer understanding of the clinical performance of this relatively new class of materials in comparison to conventional resin composites is required. Based on previous studies, the aim of the current review was to present the clinical criteria for the use of bulk-fill composites in direct restorations of posterior teeth.

Purpose: In numerous studies, MBSR programs have been shown to reduce stress and improve health-related QOL. Although MBSR programs have been shown to be beneficial, its effects have not been well-determined among Korean populations in clinical nursing practice. The purpose of this review was to describe the effects of MBSR on stress and health-related QOL so that the potential benefits of this intervention may be evaluated for wider application in Korea. Methods: Articles published in peer-reviewed journals in the English or Korean language up to 2009 were reviewed; 14 articles met the inclusion criteria for this review and there were no Korean papers. Results: MBSR groups were found to have significantly reduced stress outcomes relative to non-MBSR groups in 6 of 11 studies. In regards to health-related QOL, participants of the MBSR programs had increased scores after MBSR intervention relative to control groups in 5 of 7 studies. Conclusion: MBSR programs was effective in decreasing stress and increased the health-related QOL in the majority of studies reviewed. MBSR merits study in Korean patients to determine whether similar salutary patient outcomes may be obtained.
