Objectives: This study investigated the association between exacerbated economic hardship during the coronavirus disease 2019 (COVID-19) pandemic and changes in the health behaviors of Korean adolescents. Methods: We analyzed data from the 2021 Korea Youth Risk Behavior Survey and included 44 908 students (22 823 boys and 22 085 girls) as study subjects. The dependent variables included changes in health behaviors (breakfast habits, physical activity, and alcohol use) that occurred during the COVID-19 pandemic. The aggravation of economic hardship by COVID-19 and the subjective economic status of the family were used as exposure variables. Multiple logistic regression analysis was utilized to calculate the prevalence odds ratios (PORs). Results: Severe exacerbation of a family's economic hardship due to COVID-19 was negatively associated with the health behaviors of adolescents, including increased breakfast skipping (POR, 1.85; 95% confidence interval [CI], 1.55 to 2.21 for boys and POR, 1.56; 95% CI, 1.27 to 1.92 for girls) and decreased physical activity (POR, 1.37; 95% CI, 1.19 to 1.57 for boys and POR, 1.38; 95% CI, 1.19 to 1.60 for girls). These negative changes in health behaviors were further amplified when combined with a low subjective family economic status. Conclusions: The experience of worsening household hardship can lead to negative changes in health behavior among adolescents. It is crucial to implement measures that address the economic challenges that arise from stressful events such as COVID-19 and to strive to improve the lifestyles of adolescents under such circumstances.

Recurrent aphthous ulcer(RAU) is the most frequent form of oral ulceration with a prevalence in the general population ranging between 5% and 60%. The peak age of onset is between 10 and 19 years of age, and it can persist into adulthood and throughout the patient's lifespan, with no gender predilection. The disease is characterized clinically into three types: minor aphthous ulcer, major aphthous ulcer and herpeticform ulcers. The cause of RAU is unknown and thought to be multifactorial with many triggers or precipitating factors that include familial tendency or genetic predisposition, allergy, medications, hormones, stress or anxiety, and immunologic abnormalities. The need for consideration of psychological factors in the pathogenesis of oral disease has been increasingly acknowledged over the last decades and many studies have highlighted the psycho-social impact of oral conditions. In this study, we tried to evaluate the influence of emotional stress in RAU. There were thirty patients with a clinical diagnosis of RAU and other subjects who did not show any signs of systemic disorders include RAU. They are evaluated by using modified Holmes and Rahe's Social Readjustment Rating Scale (SRRS). As a result, a significantly higher level of stress was found in the RAU patients than the control group. Therefore it can be concluded that psychological stressors play an important role in the RAU.

Objective: Stress is known to be a common cause of short-term insomnia and insomniacs often complain that stress induces sleep problems. However, previous studies on the correlation between stress and sleep do not show consistent results. We aimed to investigate the effects of minor stressful events on sleep among college students. Method: Physically and mentally healthy college student volunteers filled out a self-assessment questionnaire to evaluate their stress and sleep. To find out the status of average stress and sleep, the volunteers filled out K-DSI and daily sleep assessments on three consecutive days. In addition, we surveyed the amount of caffeine beverage intake and assessed the degree of depression and anxiety. Results: The total number of students participating in this study was 202, 101 men and 101 women. Minor stress turned out to significantly affect non-restorative sleep and secondary symptoms of insomnia (awakening difficulty, displeasure, feeling of dissatisfaction with sleep, physical uneasiness or pain at awakening, daytime sleepiness, depressive moods, tiredness and concentration difficulty). However, global PSQI score, self-reported sleeping hours, sleep latency, awakening frequency, frequency and duration of napping, were not explained by stress scores. Conclusion: In this study, minor stresses seemed to affect sleep, especially secondary symptoms caused by non-restorative sleep. We can thus infer that minor stresses impair the restorative effects of sleep by inducing arousal, and the direct relationship the two can be confirmed by polysomnogram.

The purpose of this study was to provide the basic, data for developing a program for effective prevention for Postpartum Depression (PPD) by investigating the level of PPD in postpartum 2 weeks women. The subjects were 384 women who visited obstetrical clinics for postnatal care. The data were collected from June 29. 1999 to April. 2000, using a 46-item questionnaire related to PPD, and analyzed by SAS program for t-test, ANOVA, Scheffe test, stepwise multiple regressions. The results were as follows : 1. The level of PPD according to general characteristics Women had mild PPD (Min score; 46.0, Max score; 124.0). The PPD levels were significantly differences according to religion and marital satisfaction (p<0.05). 2. The level of PPD according to obstetrical characteristics 1) Characteristics related to pregnancy The PPD levels were significantly differences according to mood change, confidence of body weight recovery, depression related to appearance change, husband's help to housework, and husband's emotional support (p<0.05). 2) Stressful events during pregnancy The PPD levels were significantly differences according to financial problem, conflict between partners, conflict between family, and husband's job change (p<0.05). 3) Characteristics related to delivery and post natal period The PPD levels were significantly differences according to baby's health state, parenting confidence, and difficulties related to postpartum care (p<0.05). 3. The variables to predict postpartum depression in postpartum women are depression related to appearance change (10.4%), parenting confidence (8.8%), husband's help to housework (2.7%), confidence of body weight recovery (2.4%), husband's job change (1.9%), baby's health state (1.9%), difficulties related to postpartum care (1.6%), mood change (1.2%), conflict between partners (0.6%), marital satisfaction (0.5%), financial problem (0.4%). The sum total of all the above variables can account for 32.4% of postpartum depression. 4. The level of PPD according to PPD factors. Women had the highest degree of PPD in biophysiological phenomena-disturbance of physical functioning factor. The factors of relationship to baby-negative feeling and cognitive phenomena-self concept disturbance were showed the lowest degree of PPD. As a result of the above findings, a systemic and individualized program is strongly recommended for PPD prevention, diagnosis, and care for PPD in postpartum women. In near future, this study should be expanded to investigate the coping skills according to the PPD levels in postpartum women.

Objectives : This study was intended to compare coping style, family support, and parenting behavior between adolescent groups with different levels of perceived stress. Methods : A total of 795 high school students participated in this study. First, they were tested on the Perceived Stress Scale and then were separated into two groups depending on the level of perceived stress. Both groups completed the Scale for the Coping Style, the Family Environment Scale (relationship subscale) and Parenting Behavior Inventory. Results : The high stress group had significantly higher scores on all their coping scores than the low stress group. Also, the high stress group had significantly higher family conflict scores, lower family cohesiveness scores and lower expression scores than the low stress group. The high stress group experienced negative parenting behavior from both parents more often than the low stress group. In the adolescents with low family cohesiveness and expression, the use of active behavioral coping was decreased, if the higher stressful events occurred. The use of avoidant coping by these adolescents increased when there were higher levels of stress in their environment. Conclusion : Low family support directly reduced the usage of active behavioral coping and increased the use of avoidant coping strategy through the mediation of high stress condition.

Background : Behavioral stress has been suggested as one of the significant factors that is able to disrupt physiological systems and cause depression as well as changes in various body systems. The stressful events can alter cognition, learning, memory and emotional responses, resulting in mental disorders such as depression and anxiety. Results : We used a restraint stress model to evaluate the alteration of behavior and stress-related blood parameter. The animals were randomly divided into two groups of five animals each group. Furthermore, we assessed the change of body weight to evaluate the locomotor activity as well as status of emotional and anxiety in mice. After 7 days of restraint stress, the body weight had significantly decreased in the restraint stress group compared with the control group. We also observed stress-associated behavioral alterations, as there was a significant decrease in open field and forced swim test, whereas the immobilization time was significantly increased in the stress group compared to the control group. We observed the morphological changes of neuronal death and microglia by immunohistochemistry and western blot. In our study restraint stress did not cause change in neuronal cell density in the frontal cortex and CA1 hippocampus region, but there was a trend for an increased COX-2 and iNOS protein expression and microglia (CD11b) in brain, which is restraint stress. Conclusion : Our study, there were significant alterations observed in the behavioral studies. We found that mice undergoing restraint stress changed behavior, confirming the increased expression of inflammatory factors in the brain.

Objectives: The p53 tumor suppressor gene encodes a nuclear transcription factor that is critical regulator of cell growth and proliferation through its action in cell-cycle checkpoint control. The wide variety of stressful stmuli which include DNA damage, hypoxia, heat shock, metabolic changes activate the p53 protein, which in turn drives a series of events that culminate either in cell cycle arrest or apoptosis. Mutations of the p53 gene is the most common genetic alteration in human cancer. This gene is altered in approximately 40-60% of head and neck cancers. Whereas the wild-type form of the p53 protein plays a central role in cell-cycle control in response to DNA damage, most of the mutant forms are unable to do so. The high levels of p53 protein expression in tissues are related to the increased cellular proliferative activity and may be associated with the poor clinical outcome. To determine whether the expression of the p53 protein has prognostic significance and is associated with patterns of treatment failure in head and neck squamous cell carcinoma (HNSCC), We analyzed p53 overexpression in 40 cases of HNSCC. Materials and Methods: Immunohistochemical analysis with a monoclonal antibody (DO7) specific for p53 protein was used to detect expression of the protein in formalin-fixed, paraffin-embedded tumor samples from 40 HNSCC. We evaluated p53 protein expression and analyzed the relationship between the p53 overexpression and age, sex, primary tumor site, stage, survival rate, recurrence. All reported P values resulted from two-sided statistical tests. Results: Overexpression of p53 was detected in 20 cases(50%) among 40 cases of HNSCC. The p53 overexpression was not associated with age, sex, primary tumor site, stage, recurrence and survival rate. Conclusions: In our results, p53 was not significant prognostic factor in HNSCC. Based on many previous studies, It is evident that p53 has a certain role in tumorigenesis of HNSCC. So, the further study is needed to evaluate the prognostic significance of p53 in HNSCC.

Lichen planus is a chronic inflammatory mucocutaneous disease that affects multiple sites of the body. Often it involves the oral mucosa, but also involve other sites such as skin, genitals, scalp and nails. There is no clear cause of oral lichen planus (OLP), current data suggest that OLP is a T-cell mediated autoimmune disorder which may have an altered self-peptide triggering apoptosis of oral epithelial cells. Usually OLP appears in middle-aged women which tends to be chronic with periods of exacerbation and remission. There are many theories those causes the OLP such as psychological and environmental factors, genetic tendency, drugs and more. 60-70% of lichen planus is accompanied by oral lesions, and more than half of its cases are not able to defined by their skin. In this study, among all the possibility(possible) theories, we tried to evaluate the influence of emotional stress in exacerbating OLP. There were thirty patients with a clinical or histological diagnosis of OLP and other thirty subjects who did not show any signs of systemic disorders include OLP. They were evaluated by using modified Holmes and Rahe's Social Readjustment Rating Scale (SRRS). As a result, a significantly higher level of stress was found in the OLP patients than the control group. Therefore it could be concluded that psychological stressors play an important role in the exacerbating OLP.

We meet many difficult challenges from many factors such as crime, natural disasters, social unrest, financial problems, employment, and so on. It therefore essential to cope with these negative stressful events to attain a state of personal well-being. Lately in the field of psychology and psychiatry, a concept called 'resilience' has received increasing attention. Resilience embodies the personal qualities that enable one to thrive in the face of adversity. Also it refers to the process of overcoming the negative effect of risk exposure, coping successfully with adversity, and avoiding the negative trajectories associated with risks. Resilience people were expected to do their innovative work behavior well. And SUS(supervisor support), COS(coworker support), OEMC(organizational error management culture) influence the relationship of resilience between Innovative Behavior. This study focused on three question. First, how is resilience relate to individual performance in the organization? And second, are there any moderate factors between resilience and individual performance. As the result of the hierarchical regression analysis, resilience indicates positive effects on IB and IB was predicted by interaction of resilience by SUS and OEMC. Findings in this study indicated that the level of SUS and OEMC should be considered in interpreting the resilience and Innovative Behavior.

Objectives: To investigate validity and effectiveness of Saam five element acupuncture treatment in psychological problems. Methods: We selected a Korean medicine doctor known to apply Saam five element acupuncture treatment to the psychiatry field. An investigator visited the doctor's clinic to observe the cases and interview patients. Duration of each interview was 30 minutes to one hour. A semi-structured questionnaire was used for in-depth interviews. All interviews were recorded and converted into texts. Converted texts were then summarized and analyzed qualitatively. Results and Discussion: Treatment process of Saam five element acupuncture designed for psychiatric use is divided into four stages: qi transformation (氣化), acupuncture treatment, deep breathing, and acupressure. In the first stage, patients are asked to express their feelings and emotions in a physical sense; to imagine their feelings have colors, weight, and physical form, and to describe those characteristics. Next, the doctor evaluates each patient's qi according to the six qi (六氣), and then determines protocol of Saam five element acupuncture treatment. This treatment is focused on suffering of the patient and specific symptoms or emotions. The treatment duration is brief and changes in symptoms are frequently checked during treatment sessions. Without discussing details of stressful events, the doctor enables patients to express physical aspects of their feelings. He also provides them with psychoeducational resources. As a result, patients experienced immediate changes in body sensation, emotions and thinking, decreased response to triggers, and increased self-control after treatment. Conclusions: The Saam five element acupuncture treatment has the potential to be used as a treatment for psychiatric disorders. Treatment can be effective in managing psychiatric disorders when applied by primary Korean medicine clinics.
