Objectives: The purpose of this study is to understand the effect of infection anxiety about COVID-19 perceived by home appliance installers and repair technicians on work stress. Methods: To collect data, the purpose of the study was explained through the labor union of domestic home appliance service companies, and a survey was conducted through mobile to 286 home appliance installers and repair technicians who agreed to the survey. Results: As a result of the analysis, it was found that age, fatigue, work satisfaction, visit time, and Corona 19 infection anxiety had a significant effect on work stress. In other words, the higher the age, the higher the fatigue, the lower the job satisfaction, the higher the work stress was when the visit time was more than 30 minutes, and the higher the Corona 19 infection anxiety, the higher the work stress. Conclusions: Based on the results of this study, the following suggestions are made. First, in order to prevent work stress, we propose the development of a workplace health care program that can solve fatigue. Second, it is necessary to prepare a working environment and provide institutional support to reduce work stress by increasing Job satisfaction. Third, a workplace quarantine measures is needed to prevent infection for essential-workers who do face-to-face work in preparation for possible infectious diseases in the future.

Objectives: To compare Korean medicine (KM) and traditional Chinese medicine (TCM) psychotherapy for anxiety. Methods: Databases including MEDLINE (via PubMed), EMBASE (via Elsevier), Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and Oriental Medicine Advanced Searching Integrated System were comprehensively searched. Prospective clinical studies on KM or TCM psychotherapy for patients with anxiety disorder or individuals with elevated anxiety levels published up to August 3, 2022 were reviewed. Psychotherapy was divided into counselling, art therapy, and meditation according to its characteristics. Results: A total of 12 clinical studies were reviewed, including nine randomized controlled trials. The most common disorder investigated was post-traumatic stress disorder. Ten studies used TCM psychotherapy and two used KM psychotherapy. As for differences between TCM psychotherapy and KM psychotherapy, TCM psychotherapy utilized pattern identification in the procedure more actively than KM psychotherapy. In addition, some TCM studies have attempted to directly converge Western psychotherapy (i.e., hypnosis) and Eastern psychotherapy (i.e., Taoin qigong therapy). In the case of KM psychotherapy, there was an attempt to incorporate psychotherapy with Sasang constitutional medicine. Reported effects of TCM psychotherapy and KM psychotherapy on anxiety were positive. Conclusions: Research status of KM psychotherapy and TCM psychotherapy for anxiety was investigated, revealing some of their characteristics, commonalities, and differences. Findings of this review have the potential to provide a clue to the development of conventional KM psychotherapy and new medical technology for KM psychotherapy.

Objectives: This study was conducted to observe the progression of symptoms according to the treatment period of patients with social anxiety disorder who received complex Korean medicine treatment. Methods: The medical records of 25 patients who were diagnosed with social anxiety disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and received complex Korean medicine treatment (herbal medicine, acupuncture, and Korean psychotherapy) for 12 weeks were analyzed. The State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), the Korean-Social Avoidance and Distress scale (K-SAD), and the Korean-Fear of Negative Evaluation (K-FNE) were measured at the initial hospital visit and during the 4, 8, and 12 weeks of treatment to evaluate the effectiveness of treatment. Missing values were replaced with the average evaluation index value at that time. Results: 1) Statistically significant changes in STAI-X1, STAI-X2, BDI-II, BAI, K-SAD, and K-FNE scores were seen according to the time of treatment. 2) When scores were compared between each treatment time point, STAI-X2 and BDI-II showed statistically significant changes between the initial visit and four weeks of treatment, the initial visit and eight weeks of treatment, and the initial visit and 12 weeks of treatment. STAI-X1 and K-FNE showed statistically significant changes between the initial visit and eight weeks of treatment and the initial visit and 12 weeks of treatment. There was a statistically significant change in BAI scores between the initial visit and the 12th week of treatment. Conclusions: Complex Korean medicine treatment alleviated anxiety, depression, fear, and avoidance of social situation symptoms in patients with social anxiety disorder. The longer the treatment period, the more symptoms tended to be alleviated. However, the evidence should be supplemented with prospective, controlled research.

Objectives: To investigate the correlation of anxiety or depression mood with physical stress of 59 participants (29 who complained of chronic headache and 30 who did not complain of headache) using a questionnaire on chronic headache symptoms, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Heart Rate Variability (HRV). Methods: In this study, medical records of 59 participants (29 who complained of chronic headache and 30 who did not complain of headache) who completed the BAI, BDI, HRV, and Questionnaire for chronic headache symptoms were evaluated. All data were analyzed using SPSS (Statistical Package for the Social Sciences, Version 26.0). Descriptive Analysis, Mann-Whitney U test, Chi square test (Fisher's exact test), and Pearson correlation coefficient were used for data analysis. Results: 1. The chronic headache group had significantly lower SDNN, RMSSD, TP, LF, and HF values on HRV than the general control group. 2. As BAI and BDI scores of the chronic headache group increased, the overall HRV value tended to decrease, indicating a deep association. 3. There was a negative association between BDI and HRV values in the chronic headache group, although such association was not statistically significant. Conclusions: BDI can be negatively correlated with HRV (SDNN, RMSSD, TP, LF, HF) in chronic headache patients.

PURPOSE: This study examined the comparative effects of an ankle sensorimotor training program combined with hip strengthening exercise (ASTPCHSE) and ankle sensorimotor training program (ASTP) alone on muscle strength, static balance, and dynamic balance in individuals with functional ankle instability. METHODS: Sixteen research participants with functional ankle instability were enrolled in this study. The participants were divided randomly into the ankle sensory motor training program group and the ankle sensory motor training program combined with the hip strengthening exercise group. Each group performed a series of exercise programs two times per week for four weeks. The Cumberland ankle instability tool (CAIT) was used to measure the participants' functional ankle instability. A Balance trainer 4 was applied to assess the static and dynamic balance, and a Primus RS multimodal dynamometer was used to evaluate the muscle strength. RESULTS: No significant differences in static balance, dynamic balance, and muscle strength were found between the ASTP and ASTPCHSE groups (p > .05). On the other hand, the dynamic balance and muscle strength improved in the ASTP and ASTPCHSE groups after the intervention (p < .05). The static balance was not enhanced in both groups after the intervention (p > .05). CONCLUSION: Ankle exercise and an ankle sensorimotor training program combined with hip strengthening exercise are effective in improving muscle strength and dynamic balance in individuals with ankle instability. On the other hand, there are no meaningful differences between ankle exercise and ankle and hip combined exercise.

PURPOSE: This study examined the relationship between lumbar instability and shortening of the iliopsoas muscles in patients with chronic low back pain. METHODS: Forty-nine patients with chronic low back pain participated in this study. The modified Thomas test was used to examine the shortening state of the iliopsoas muscle. The length of the iliopsoas muscle was measured using the hip flexion angle, and those with a flexion angle of 10° or more were classified as positive. Five subtests were used for the lumbar instability test: testing for prone lumbar instability, passive lumbar extension, anterior-posterior mobility, passive straight leg raise, and age. Those who tested positive for at least three of these tests were classified as positive for the lumbar segment instability test. RESULTS: There was a significant association between the results of the lumbar instability test and the shortening of the iliopsoas test (p < .05). After analyzing the association between the iliopsoas length test and the five lumbar instability subtests, the results of the prone lumbar instability test (p < .001) and the anterior-posterior mobility test (p < .05) showed a significant association with the iliopsoas length test. CONCLUSION: The association between lumbar instability and shortening of the iliopsoas muscles was examined in 49 patients with chronic low back pain. Patients with shortened iliopsoas muscles tested positive in the lumbar instability tests more often. Hence, the length test of the iliopsoas muscle can be used to determine lumbar instability in patients with chronic low back pain.

Purpose : This study aimed to examine the relationship between sleep quality and its influencing factors in patients with coronary artery disease (CAD). Methods : This descriptive correlational study included 130 patients with CAD admitted to the cardiology department of a general hospital in B City between September 2019 and February 2020. Data were collected using structured questionnaires and research instruments to measure sleep quality, anxiety, depression, chronotype, and daytime sleepiness. Results : The mean scores for sleep quality, daytime sleepiness, anxiety, and depression were 7.59±3.45, 6.45±3.46, 6.58±3.88, and 7.74±4.05, respectively. In terms of chronotypes, 10.8%, 48.5%, and 40.7% of the participants had evening-, intermediate-, and morning-type patterns, respectively. Sleep quality was significantly correlated with anxiety (r=0.38, p<.001), depression (r=.37, p<.001), and daytime sleepiness (r=.26, p =.002). Factors associated with sleep quality in patients with CAD included anxiety (β=.29), heart failure (β=.22), daytime sleepiness(β=.21), and sleeping alone (β=.19). Collectively, these factors had an explanatory power of 23.1% for sleep quality variance. Conclusion: Patients with CAD often experience poor sleep quality owing to various factors such as anxiety, daytime sleepiness, heart failure, and sleeping alone. It is recommended that healthcare providers objectively evaluate sleep and identify factors that influence sleep quality. This will enable the development of effective methods for sleep management as part of nursing care.

The study on waiting time has been conducted from the psychological perspective since Maister (1985). In using medical institutions, especially general hospitals, it is not avoidable to wait for a long time. As a result, the waiting time gives clients psychological stress, which causes medical consumers to be more dissatisfied and decreases their rate of revisit. Accordingly, it is very urgent to study on the waiting time for hospitals' marketing and better image-making. This study is intended to find out how hospitals image and clients revisit is influenced by waiting environment and consumers' attitude, variables of waiting time perceived in medical services. Based on this study, those medical institutions are required to improve their medical service and waiting environment. Accordingly, they should convert waiting time into more efficient and comfortable recess and provide better environment for physical service and effective human services. As those medical institutions have relatively worse image than other businesses, they should actively study on ways of better image-making in the future.

Cell division is an essential process for the survival and development of living organisms. It is critical that duplicated chromosomes are properly segregated into daughter cells during mitosis. The centrosome is the core organelle that forms the microtubule-organizing center (MTOC), which generates the microtubules that make up the mitotic spindle during cell division. The centrosome is also involved in cell signaling and motility. In normal cells, there is one centrosome in G1 that replicates into two in the S phase and matures through G2. During the M phase, duplicated centrosomes move to both ends of the cell, and spindle microtubules that are generated from MTOC move the chromosome to both ends. The cells then split into two to complete the cell division. However, a phenomenon called centrosome amplification (CA), in which the number of centrosomes is higher than normal, is common in cancer cells and can lead to chromosome instability (CIN). This paper discusses the process of centrosome replication and the role of PLK4 in this process. The possible consequences of centrosome amplification and how the PLK4 inhibitor may be able to treat certain types of cancer cells, such as breast cancer and neuroblastoma, will also be discussed.
