Purpose: This study was conducted to develop and to determine the effects of an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention. Methods: Subjects consisted of 58 CAD patients (experimental group: 30, control group: 28). The experimental group participated in an integrated symptom management program for 6 months which was composed of tailored education, stress management, exercise, diet, deep breathing, music therapy, periodical telephone monitoring and a daily log. The control group received the usual care. Results: The experimental group significantly decreased symptom experiences and the level of LDL compared to the control group. The experimental group significantly increased self care activity and quality of life compared to the control group. Although no significant difference was found in cardiac recurrence, the experimental group had fewer recurrences. Conclusion: These results suggest that an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention can improve symptom aggravation, recurrent rate, self care activity and quality of life. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented in the overall transition period.

Acoustic emission(AE)/Microseimsic(MS) activities are low-energy seismic events associated with a sudden inelastic deformation such as the sudden movement of existing fractures, the generation of new fractures or the propagation of fractures. These events rapidly increase before major failure and happen within a given rock volume and radiate detectable seismic waves. The main difference between AE and MS signals is that the seismic motion frequencies of AE signals are higher than those of MS signals. As the failure of geotechnical structures usually happens as a high velocity and small displacement, it is not easy to determine the precursor and initiation stress level of failure in displacement detection method. To overcome this problem, AE/MS techniques for detection of structure failure and damage have recently adopt in civil engineering. In this study, AE/MS monitoring system, which consist of sensor, data acquisition and operation program, is constructed with domestic technology. To verify and optimize the developed system, we are now carrying out the field application at an underground research laboratory and the developed AE/MS monitoring will be used in detecting of seismic events with various scales.

The effects and roles of social support and stressors (stressful life events and chronic strains) on psychosocial distress were examined in a model with data from a sample of the white-collar workers (N=416) in Korea. The findings of this study present that mean levels of psychosocial distress were higher in the female, youth, unmarried and divorced, and low economic status (monthly income). The analysis also shows that, as expected, stressful life and chronic strains as stressors are positively related to occurrence of psychosocial distress, and social support is negatively related to psychosocial distress. Further, the contribution of social support to predicting psychosocial distress is greater in magnitude than that of stressful events, chronic strains, and seciodemographic variables. There is no evidence that social support buffers the impacts of stressors on psychosocial distress, rather social support takes a role of mai or direct effects on psychosocial distress. Therefore, the strength of the social support is an important and meaningful strategy to prevent from stress and mental, physical illness.

Objectives: Self-rated health is a measure of perceived health widely used in epidemiological studies. Our study investigated the determinants of poor self-rated health in middle-aged Korean adults with diabetes. Methods: A cross-sectional study was conducted based on the Health Examinees Study. A total of 9759 adults aged 40 to 69 years who reported having physician-diagnosed diabetes were analyzed with regard to a range of health determinants, including sociodemographic, lifestyle, psychosocial, and physical variables, in association with self-rated health status using multivariate logistic regression models. A p-value <0.05 was considered to indicate statistical significance. Results: We found that negative psychosocial conditions, including frequent stress events and severe distress according to the psychosocial well-being index, were most strongly associated with poor self-rated health (odds ratio $[OR]_{\text{Frequent stress events}}$, 5.40; 95% confidence interval [CI], 4.63 to 6.29; $OR_{\text{Severe distress}}$, 11.08; 95% CI, 8.77 to 14.00). Moreover, younger age and being underweight or obese were shown to be associated with poor self-rated health. Physical factors relating to participants' medical history of diabetes, such as a younger age at diagnosis, a longer duration of diabetes, insulin therapy, hemoglobin A1c levels of 6.5% or more, and comorbidities, were other correlates of poor reported health. Conclusions: Our findings suggest that, in addition to medical variables, unfavorable socioeconomic factors, and adverse lifestyle behaviors, younger age, being underweight or obese, and psychosocial stress could be distinc factors in predicting negative perceived health status in Korean adults with diabetes.

By using two methods we obtained plane solutions for 5 groups of earthquakes including 13 events, which occurred in the central region of South Korea after December 1997. The first method is the composite fault plane solution by P wave polarity, and the second the solution by amplitude ratio (SV/P, SH/P, SV/SH) and P and S wave polarities. The two method results show similar results. The strike of fault is in the direction of NNE-SSW and WNW-ESE with the movement of strike-slip or strike-slip including thrust component. The compressional axis of the stress field dominantly trends ENE-WSW or NE-SW. The results are almost consistent with the other main events occurred in and around the Korean Peninsula.

Mutations in spliceosome components have been implicated in carcinogenesis of various types of cancer. One of the most frequently found is U2AF1 S34F missense mutation. Functional analyses of this mutation have been largely limited to hematological malignancies although the mutation is also frequently seen in other cancer types including lung adenocarcinoma (LUAD). We examined the impact of knockdown (KD) of wild type (wt) U2AF1 and ectopic expression of two splice variant S34F mutant proteins in terms of alternative splicing (AS) pattern and cell cycle progression in A549 lung cancer cells. We demonstrate that induction of distinct AS events and disruption of mitosis at distinct sub-stages result from KD and ectopic expression of the mutant proteins. Importantly, when compared with the splicing pattern seen in LUAD patients with U2AF1 S34F mutation, ectopic expression of S34F mutants but not KD was shown to result in common AS events in several genes involved in cell cycle progression. Our study thus points to an active role of U2AF1 S34F mutant protein in inducing cell cycle dysregulation and mitotic stress. In addition, alternatively spliced genes which we describe here may represent novel potential markers of lung cancer development.

When a traumatic subject experiences extreme stress, various psychiatric problems, including PTSD, can occur if they do not respond appropriately. In addition, non-war soldiers who experience life-threatening events while serving in the military may experience severe and chronic PTSD symptoms. However, there are still insufficient domestic studies on what traumatic events soldiers are exposed to and how much PTSD symptoms they experience. Therefore, this study provides a method that can be used as basic data for PTSD and psychological support of military service personnel by identifying trends in domestic research. Furthermore, it studies PTSD not only of soldiers but also of 'civilians' who have experienced combat, and provides symptomatic treatment and relief programs to civilians according to the difference in PTSD between general trauma and war trauma. It is expected that these studies will increase military confidence and enable the military to play a leading role in war trauma PTSD research and prevention, treatment and mitigation.

Purpose: This study aimed to assess exposure to traumatic events, knowledge and attitudes concerning post-traumatic stress disorder (PTSD) and the level of resilience among nurses and paramedics working in emergency departments. Methods: Data were collected from May 22 to June 12, 2022, using a self-administered survey questionnaire. The participants comprised 135 nurses and 80 paramedics working in emergency departments. The collected data were analyzed with descriptive statistics, a t-test, and an analysis of variance with Scheffé's test. Results: Compared with emergency room nurses, paramedics were more positive about the government's spending on job opportunities for people with PTSD. There were no significant differences in attitude regarding government strategies and people with PTSD between nurses and paramedics. Paramedics had higher scores on the effective treatment for PTSD, while emergency room nurses showed higher scores on effective psychotherapy. General knowledge of PTSD differed according to sex (t=-2.33, p=.021) and education level (F=3.21, p=.042). Resilience scores differed significantly according to sex (t=2.02, p=.045), education level (F=4.10, p=.018), self-reported economic state (F=10.34, p<.001), and self-reported health (F=11.57, p<.001). Conclusion: The findings support that emergency department nurses and paramedics are in need of self-care programs to support their mental health and indicate that intervention programs should be developed to enhance resilience in emergency department professionals.

This study was performed to investigate the degree of different stresses in university students of outer region of Seoul and to search the influence of food habit and nutrient intakes in stress. The data was collected by questionnaire method for self-diagnosed different stresses, dietary habit, and physical status and 24 hours recall for nutrient intakes. The subjects were 282 students attended at the lecture Food and Health. Diet balance was no difference with gender but food intakes were more diverse in female. Nutrient intake of male students was lower in vitamin A and riboflavin, but that of female was low in vitamin A and iron. The university students outer region of Seoul had more stress situation in frustration, deprivation and self-efface than in the stress of the noise and Type-A behavioral stress. Total self-diagnosed dietary habit score was better in the group of no susceptive overload stress than that of the high susceptive group. Same trend of dietary behavior score was in the group of no noise and anxiety-response stress than that in the susceptive groups. The quantity of nutrient intakes was correlated with different kind of stress. Niacin intake was positively related with the stress from life-events, and food induced stress. Thiamin intake was positively related with food induced stress. But the intake of iron, calcium, niacin and riboflavin were negatively related with the stress of noise. Therefore, we could concluded that different kind of stresses were influenced in dietary behavior and vitamin-mineral nutrient intakes. More research would be needed at the aspects of health promotion in the stressful situation of modern society.

Purpose : The purpose of this study was to investigate the depression, self-efficacy, and stress level of middle-aged women and to identify the factors affecting on stress, and to provide base line data for the development of nursing intervention for stress reduction of middle-aged women. Methods : Participants were 200 middle-aged women aged 40 to 60 who live in Seoul and Gyeonggi Province. Data collection period was from March 1, 2019 to April 15. In this study, the questionnaire of life events-stress, depression scale, self-efficacy was used. Data were analyzed by average, standard deviation, minimum, maximum, correlation and regression using the SPSS Program 21.0. Results : The results of this study, the correlation between depression, self-efficacy and stress in middle-aged women, depression and self-efficacy (r=-.264, p<.001), self-efficacy and stress (r=-.279, p<.001) had a significant negative correlation, depression and stress (r=.268, p<.001) had a significant positive correlation. Depression and self-efficacy were the factors affecting the stress of middle-aged women. Depression was β =.207 (p<.001) and self-efficacy β =-.222 (p=.003). Depression had the greatest influence on stress, followed by self-efficacy. Conclusion : Middle-aged women are an important time to prepare for a successful old age. Considering that the current middle-aged women are the subjects of the future aging society, their physical, psychological, and social problems are very important in preventing the elderly problems of the aging society. Therefore, effective nursing interventions should be developed that to reduce the depression and stress in middle-aged women and to improve self-efficacy and improve the quality of life of middle-aged women.
