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.

Purpose: This study aimed to determine the level of postpartum posttraumatic stress disorder (PTSD) and postpartum depression (PPD) in Korean mothers with healthy babies and to explore the factors related to postpartum PTSD. Methods: This study used a longitudinal survey design to explore the levels and association of PPD and PTSD. Two hundred women were recruited during pregnancy and the data were collected via online survey from 166 mothers (84% retained) who gave birth to healthy babies, at two postpartum periods: Fear of childbirth was assessed at the 1st week; and spousal support, PPD, and postpartum PTSD were surveyed at the 4th week postpartum. Descriptive statistics, t-test, one-way analysis of variance, Chi square test, and multiple regression were done. Results: The mean age of mothers was 33.12 (±3.97) years old. Postpartum PTSD was low (8.95±6.49) with 1.8% (n=3) at risk (≥19). PPD was also low (6.68±5.28) and 30.1% (n=50) were identified at risk (≥10). The comorbid rate of PPD with PTSD was 6%. Mothers who did not have a planned pregnancy had higher scores of PPD (t=-2.78, p=.008), whereas spousal support and PPD had negative relationship (r=-.21, p=.006). The overall explanatory power for postpartum PTSD was 55.2%, of which PPD was the only significant variable (β=. 76, t=13.76, p<.001). Conclusion: While only 1.8% was at risk of postpartum PTSD at 4 weeks postpartum, PPD prevalence was 30.1% and PPD was the only influential factor of postpartum PTSD. Assessment and counseling of PPD are required as well as screening for postpartum PTSD. More research is also needed on postpartum PTSD in Korean women.

The purpose of this paper is to assert the necessity of social health as a solution to resolve social issues of the aged in the nearing aged society, and to assess the effects that the social health of the aged has on their quality of life. In doing so, the study gathered as its study subjects those aged persons who participate in social activities among persons aged 65 or older who reside in Euiwang-si, Gyeonggi-do. A total of 157 subject studies were used for the final analysis. An analysis of frequency, t-Test and one-way ANOVA, Duncan post-test, correlation analysis and hierarchical regression analysis was conducted by using the IBM SPSS 21.0. The main study findings are as follows. with respect to the correlation between socio-demographic factors and social health, economic level, subjective level of health and social health showed a positive correlation. Domiciliary treatment level and subjective level of health showed a negative correlation with economic level and social health, respectively. with respect to the effects of social health on quality of life, in the case of model 1 which only input factors of socio-demographical characteristics, the variance explanation power was found to be 38.2% and the regression model was found to be significant (F=13.141, p<.001). In the case of model 2 which input factors of socio-demographical characteristics and social health, the variance explanation power was found to be 13.8% and the regression model was found to be significant (F=20.057, p<.001). Based on such study results, this study recommends a number of proposals.

Studies were conducted from May, 1993 to April, 1995 to determine the changing patterns of infection Ity the liver fluke, Clonorchis sinensis, among residents and fish hosts in Kyongbuk Province. The infection rate among residents was 7.7% by stool examination. The rate in males (11.3%) was significantly higher than females (4.1%) Positive rate of intradermal test was 27.6% in the same population. The special type of a simple catalytic model was applied for the analysis of intradermal positive reactors by age arid sex, ann the equation was Y= 0.4776 t (1 -e-0.0375t) for mates ann, y : 0.2085 (1-e-0.0138t) for females. Analysis of stool examination data by two-stage catalytic model revealed y : 0.025 (e-0.0047t _ e-0.0235t). The annual Clonorchis infection rate was 4.7 per 1,000 susceptibles and the annual loss rate was 23.5 per 1,000 infected. The frequency distribution by the eggs per gram (EPG) was calculated as well as the cumulative percentages of positives. The regression equations were y : 0.929+ 1.506 log x for males and, y : 0.473 + 1.767 log x for females. Of the 25 fish species, 7 species were infected with Clonorchis mrtacercariae. Infection rates varied by the species, and ranged from 2.8% in Punfun,Bia herzi to 30.0% in Pseudorasbora panic. Average number of the matacercariae per gram of flesh was 58.1 in p. pnnpa, followed by 10.2 in Gncthopogon atromoculntus, 7.0 in Saurosobio dobryj, and 3.0 in Pcrccheilogncthus rhonlben. The present study indicates that clonorchiasis in Kyongbuk Province is less prevalent than that of several decades ago.

This study was to validate the WSSECT (Workplace Spirituality Scale for Early Childhood Teacher) using discriminant analysis on early childhood teachers' happiness and job satisfaction. The data from 504 teachers working at kindergartens and daycare centers were analyzed statistically through t-test and discriminant analysis. The results indicated that 1) the higher group in workplace spirituality significantly gets more scores of happiness and job satisfaction than the lower group, 2) 4 factors of the WSSECT have discriminant power on early childhood teachers' happiness, and 3) 2 factors ('meaning for life' and 'calling for ECE teacher job') of the WSSECT are effective to discriminate early childhood teachers' job satisfaction. Further statistical works are supplementary needed to validate the WSSECT and to increase its'feasibility.

Computation of the elasto-plastic solution of ball indentation was carried out by the quadratic programming method. The problem was formulated as an elasto-plastic contact problem under the assumption of small displacement and small deformation and then transformed into a minimization problem. Finite element approximation resulted in a quadratic programming problem. Numerical and experimental study were done with aluminium Al 2024-T351 and commercially pure copper. The computed load-displacement curves were in good agrement with those obtained from experiments. Tabor's relationship for representative strains was also examined. Stress distributions were found to resemble closely those results available in the literature.

Nowadays various simulation tools are widely used for the design and the analysis of power electronic converters. From the engineering point of view it is rather difficult to parameterize power semiconductor device models without the knowledge of basic physical parameters. In recent years some data sheet driven behavioral models or so called 'wizard' tools have been introduced to solve this problem. In this contribution some experiences with some user-friendly power semiconductor models will be discussed. Using special simulation test circuits it is possible to get information on the static and dynamic behavior of the parameterized models before they are applied in more complex schemes. These results can be compared with data sheets or with measurements. The application of these models for power loss analysis of inverter type arc welding power sources will be described.
