We fabricated BiAlO thin film by a solution process with a brush coating to be used as liquid crystal (LC) alignment layer. Solution-processed BiAlO was coated on the glass substrate by brush process. Prepared thin films were annealed at different temperatures of 80℃, 180℃, and 280℃. To verify whether the BiAlO film was formed properly, X-ray photoelectron spectroscopy analysis was performed on Bi and Al. Using a crystal rotation method by polarized optical microscopy, LC alignment state was evaluated. At the annealing temperature of 280℃, the uniform homogenous LC alignment was achieved. To reveal the mechanism of LC alignment by brush coating, field emission scanning electron microscope was used. Through this analysis, spin-coated and brush coated film surface were compared. It was revealed that physical anisotropy was induced by brush coating at a high annealing temperature. Particles were aligned in one direction along which brush coating was made, resulting in a physical anisotropy that affects a uniform LC alignment. Therefore, it was confirmed that brush coating combined with BiAlO thin film annealed at high temperature has a significant potential for LC alignment.

Objective: The purpose of this study was to investigate the effect of neck stabilization exercise combined with vibroacoustic sound on patients with chronic neck pain and tension-type headache. Design: Two group pre test - post test design. Methods: 36 patients participated. Headache impact test-6(HIT-6), numerical rating scale(NRS) and muscle characteristics were measured at pre-post test. Participants divided into vibroacoustic sound group(VSG, n=18), control group(CG, n=18). VSG performed neck stabilization exercise and vibroacoustic sound stimulation. CG performed neck stabilization exercise. Both groups participated 3 times a week for a total of 4 weeks. Results: NRS showed a significant difference before and after intervention in both groups (p<0.05). HIT-6 showed a significant difference before and after intervention in the VSG group (p<0.05). Muscle tone showed a significant difference before and after intervention in the experimental group (p<0.05). There was no significant difference in muscle stiffness and muscle elasticity before and after the intervention in both groups (p>0.05). Conclusions: Based on the results of the study, it is thought that sonic vibroacoustic sound can be established as an effective treatment tool through a study applied to various diseases and symptoms.

Purpose: This study is to establish a structural model for standard precautions compliance of nursing students. This conceptual model was based on the IMB (Information-Motivation-Behavioral skills) model of Fisher and Fisher. Methods: Data were collected from October 12 to December 1, 2020, and the subjects were nursing students from G metropolitan city and J province, and the data of a total of 334 subjects were analyzed. For data analysis, this study used the SPSS 24.0 and AMOS 24.0 programs. Results: The hypothetical model showed a good fit to the data: 𝑥²=106.46 (p<.001), 𝑥²/df=2.54, RMSEA=.07, SRMR=.04, CFI=.96, TLI=.94. It was confirmed that the variables that have a statistically significant influence on the standard precautions compliance in nursing students were in the order of self-efficacy, social support, personal attitude, and standard precautions knowledge. The model explained 48.3% of the variance in standard precautions compliance of nursing students. Conclusion: It is necessary to develop and apply various specialized extracurricular programs that can induce an individual attitude toward observing standard precautions compliance in a positive direction in relationships with teachers and peers and gain their support.

The purpose of this study aims to investigate how consumer awareness and purchasing behavior are affected by the type of animosity against the nation. This study classified animosity into three categories: sociocultural, economic, and war-based. Additionally, the consumer's cognition toward animosity was split into two categories-empathic concernt and personal distress-and the direction of consumption behavior was split into two categories-individual brand avoidance behavior and collective bandwagon behavior. The concept of Fear of Missing Out (FoMO) was introduced for the direction of consumption behavior, further validating the moderating impact. Structural equation modeling method was used to measure the general consumption behvior of Korean consumers' animosity. The results were analyzed using a total of 279 samples. As a result, animosity motivated by war and by economics had a substantial impact on empathic concern, while animosity motivated by socioculture had a significant impact on personal distress. Personal distress had a good impact on an individual's brand antipathy behavior, which in turn led to brand dislike and avoidance. Empathic concern also had a positive impact on the phenomena of group sympathy, which leads to identification of conduct and social conformity. Also, it was proven that the group that had a high level of FoMO reacted strongly to the phenomenon of group collective behavior.

In this note, using the separation theorem for convex sets, we will give a two functions version generalization of Fan's minimax theorem by relaxing the convexlike assumption to the weak convexlike condition.

The Swyer-James syndrome is rare abnormality that may be encountered on routine chest X * ray examination and frequently presents a diagnostic problem. Recently, we experienced a case of Swyer-James syndrome which was accompanied with ipsilateral uncontrolled pneumothorax. We performed exploratory thoracotomy because of failure of re-expansion of the lung. Right pneumonectomy was performed and postoperative course was uneventful.
