The current study examined the relationships between disaster victims' post-trauma risk and posttraumatic growth, and the mediational role of social support for this relationships. In addition, we tested the hypothesis that income status would moderate the relationship between post-trauma risk and subjective well-being. Two hundred disaster victims completed Post-trauma Risk Checklist (PRC), Posttraumatic growth scale, Social support scale and Concise Measure of Subjective Well-Being (COMOSWB) as well as questions about their demographic characteristics. Results showed that those with high post-trauma risk demonstrated significantly higher levels of posttraumatic growth as compared to those with low post-trauma risk and social support partially mediated this relationship. Also, high levels of post-trauma risk predicted low levels of recent subjective well-being. Participants with high income obtained higher subjective well-being than did those with low income among high post-trauma risk groups. Implications for post-trauma risk and posttraumatic growth are discussed.

Purpose: To evaluate the influence of how the trauma care system is applied on the management of trauma patients. Methods: We divided the patients into a pre-trauma system group and a post-trauma system group according to the time when we began to apply the trauma care system in our institution. We compared the general characteristics, injury severity score, initial response time to the trauma patients, number of preventable deaths, and clinical outcomes between the two groups. Results: The numbers of patients in the pre-trauma system group and the post-trauma system group were 188 and 257, respectively. No differences in the patient's median ages, trauma scores (ISS, RTS, TRISS) and proportions of severe trauma patients (ISS>15) were observed between the two groups. The number and the proportion of patients who were admitted to our hospital were increased in the post-trauma system group. The time interval from trauma CP activation to emergency surgery or angio-embolization, and the patient's time spent in emergency room were shortened in the post-trauma system group. However, the lengths of the ICU stay and the hospital stay, and the number of in-hospital mortalities were not improved in the post-trauma system group. In severe trauma patients (ISS>15), there were no differences between the two groups in the number and the proportion of admitted patients, and the time interval from trauma CP activation to performing a diagnostic and therapeutic procedure was not shortened in the post-trauma system group. Conclusion: Application of the trauma care system has shortened the time between the initial response and patient management. However, this improvement was not enough to result in better clinical outcomes. More trauma physicians, multidisciplinary cooperation, and a well-organized trauma management process will be needed if the maximum efficacy of the trauma system is to be achieved.

This study was performed to investigate the effects of dietary protein content on recovery of laparotomized rats in terms of urinary epinephrine and norepinephrine plasma epinephrine and norepinephrine, . Fortyeigh male Sprague Dawley rats average-weighing 160g were divided into two diet groups ; LPD(10% low protein diet) group HPD(25% high protein diet) group After 3 days of adaptation period rats were given experimental diet for 14 days. Experimental period consists of 7-days pre-trauma and 7-days post-trauma period. Rats were laparotomized by 4cm abdominal incision under sodium pentobarbital anesthesia. During 7-days before and after the surgery urine and plasma were collected for the analysis of epinephrine and norepine-phrine. The results are as follows: 1) After laparotomy urinary epinephrine level was not increased in two diet groups. Urinary epinephrine concentration of rats in LPD group was considerably increased in post-trauma day 3 and thereafter gradually reduced. By post-trauma day 4 however urinary epinephrine concentration of rats in HPD groups was recovered to pre-trauma level 2) Urinary norepinephrine concentration of rats in LPD group was significantly increased after trauma(p<0.01) and the difference between LPD and HPD in post-trauma average norepinephrine concentration was not significant. 3) Post-traum average plasma epinephrine concentration was higher but not significant than that of pre-truma average in both groups [LPD(19.88ng/ml vs 20.93ng/ml) HPD(17.20ng/ml vs 19.37ng/ml)] 4) Plasma norepinephrine concentration of rats in LPD group was significantly increased in post-trauma period(p<0.01) In HPD group however post-trauma average plasma norepi-nephrine concentration was significantly lower than pre-trauma average. Thus the results suggest that norepinehrine concentration was affected by trauma and rats in HPD group excreted less amount of norepinephrine than rats in LPD group.

Objectives : Chronic post-thoracotomy pain is a refractory condition that responds poorly to existing pain treatments. The aim of this report is to describe favorable symptom changes in a patient with chronic post-thoracotomy pain after major chest trauma who received a series of manual acupuncture treatments over 3 months. Methods : Twelve sessions of manual acupuncture were provided to the patient, once or twice a week. Results : The manual acupuncture sessions were well tolerated. Minor adverse events, including temporary minor bleeding at the needled sites, were intermittently observed. The patient's symptoms, including pain, sleep disturbance, and anxiety gradually resolved and had almost completely disappeared after 12 sessions of acupuncture treatment. Conclusion : This single case report cannot confirm whether the observed positive changes in the patient's symptoms and dysfunctions are associated with the acupuncture treatments. Randomized controlled trials are necessary to explore the role of acupuncture in chronic post-thoracotomy pain in patients with major chest trauma.

Purpose: The present study aimed to evaluate the influence of how the trauma care system applied on the management of trauma patient within the region. Methods: We divided the patients in a pre-trauma system group and a post-trauma system group according to the time when we began to apply the trauma care system in the Halla Hospital after designation of a trauma center. We compared annual general characteristics, injury severity score, the average numbers of the major trauma patients, clinical outcomes of the emergency department, and mortality rates between the two groups. Results: No significant differences were found in the annual patients' average age ($54.1{\pm}20.0$ vs. $52.8{\pm}18.2$, p=0.201), transportation pathways (p=0.462), injury mechanism (p=0.486), injury severity score (22.93 vs. 23.96, p=0.877), emergency room (ER) stay in minutes (199.17 vs. 194.29, p=0.935), time to operation or procedure in minutes (154.07 vs. 142.1, p=0.767), time interval to intensive care unit (ICU) in minutes (219.54 vs. 237.13, p=0.662). The W score and Z score indicated better outcomes in post-trauma system group than in pre-trauma system group (W scores, 2.186 vs. 2.027; Z scores, 2.189 vs. 1.928). However, when analyzing survival rates for each department, in the neurosurgery department, in comparison with W score and Z score, both W score were positive and Z core was higher than +1.96. (pre-trauma group: 3.426, 2.335 vs. post-trauma group: 4.17, 1.967). In other than the neurosurgery department, W score was positive after selection, but Z score was less than +1.96, which is not a meaningful outcome of treatment (pre-trauma group: -0.358, -0.271 vs. post-trauma group: 1.071, 0.958). Conclusions: There were significant increases in patient numbers and improvement in survival rate after the introduction of the trauma system. However, there were no remarkable change in ER stay, time to ICU admission, time interval to emergent procedure or operation, and survival rates except neurosurgery. To achieve meaningful survival rates and the result of the rise of the trauma index, we will need to secure sufficient manpower, including specialists in various surgical area as well as rapid establishment of the trauma center.

Objectives: This study was conducted to analyze the impact of safety/health managers' experience of trauma case on their post traumatic stress disorder and the mediation effects of job stress and the moderated mediation effects of social support. Method: Using a structured questionnaire, data were collected from 241 workplace safety/health managers with experience in trauma case. The collected data were analyzed using SPSS(IBM. Ver.26.0) and verified through SPSS PROCESS Macro (Ver. 3.4). Results: The trauma case experience and the job stress, which is a mediation variable, had a statistically significant positive effect on post-traumatic stress disorder, and the job stress had a positive mediation effect in the relationship between the trauma case experience and post-traumatic stress disorder. Social support had a statistically significant negative moderation effect in the relationship between the trauma case experience and job stress; social support had a moderated mediation effect on the indirect effect of a job stress on the post-traumatic effect through a trauma case experience. Conclusion: The above findings suggest that work-related job stress management is important in order to reduce safety/health managers' post-traumatic stress disorder caused by the experience of trauma case, and that social support is essential to reduce the job stress, which can later be used as a basis for further studies.

The purpose of this study was to identity the distribution of post-traumatic stress types and coping methods and to find the relationship between the post-traumatic stress types and the coping methods, for firefighters who experienced in Dea-Gu Subway Fire Disaster. The Subjects of this study were 126 firefighters who experienced Deagu Subway Disaster. Q questionnaire developed by Q-study and coping methods instrument based on that of Folkman & Lazaruswas revised and complemented by Kim Jung Hee was used. Data were analyzed by t-test, ANOVA using SPSS. The results of this study were as follows : 1. The distribution of post-traumatic stress types were 52.4% of Emotional arousal trauma, 34.1% of Trauma experience persistence and 13.5% of Physiological symptom experience. 2. The difference of post-traumatic stress types according to the general characteristics were significantly related to the physical injury(p = .010). 3. The minimum score of coping with post-traumatic stress types was 0.07, the maximum was 2.96 and the mean score was 1.27. 4. The coping methods according to the general characteristics were significantly different at active coping method according to educational level(p = .001), passive coping method according to educational level(p = .003) and passive coping method according to diagnosis(p = 0.20). 5. The mean score of active coping method according types were Emotional arousal trauma(1.505), trauma experience persistance(1.322) and Physiological symptom experience(1.276). The mean score of passive coping method related with types were Emotional arousal trauma(1.328), trauma experience persistance(1.254) and Physiological symptom experience(1.219).

This study identified the relationship between deliberate rumination of adults who experienced traumas and post-traumatic growth, and examined the mediating model of meaning of life moderated by trauma intensity on deliberate rumination and post-traumatic growth. Participants were 318 male and female adults who experienced traumas. The moderated mediating effect was analysed with PROCESS Macro 3.5 Model 7. Results revealed that deliberate rumination of adults who experienced traumas was positively correlated with trauma intensity, meaning of life, and post-traumatic growth, while meaning of life was positively correlated with post-traumatic growth. In a moderated mediating model for post-traumatic growth, there was significant interaction effect of deliberate rumination and trauma intensity; conditionally indirect effect of deliberate rumination was only significant for whose trauma intensity were high. These findings suggest that adults who did deliberate rumination are more likely to experience post-traumatic growth with finding meaning of life. And, the moderating effect suggests that this influence is only with higher levels of trauma intensity. In conclusion, deliberate rumination of severe traumatic event may lead to post-traumatic growth, and it can be helpful to experience the meaning of life in the process.

Background: Hemorrhoid is one of the most common surgical diseases occurring in the anorectal region. In this study, we evaluated the effect of ischiorectal fossa block on alleviating post hemorrhoidectomy pain. Methods: In this study, 90 patients suffering from hemorrhoids were evaluated. They were randomly divided into 3 groups. The first group had no block, the second group an ischiorectal block with placebo (normal saline), and the third group a preemptive ischiorectal block with bupivacaine. Postoperative variables such as pain intensity, pethidine consumption, nausea, and vomiting were compared between the groups. Results: The postoperative pain score in group 1 was $8.5{\pm}1.3$ and $8.1{\pm}0.9$ (P=NS) in group 2. The post operative analgesic demand was $3.1{\pm}1.5$ and $3.3{\pm}1.8$ hours in groups 1 and 2, respectively (P=NS). The post operative pain score and analgesic demand were $4.2{\pm}2.1$ and $9.3{\pm}2.7$ hours, respectively, in group 3 (P < 0.0001). Conclusions: Preemptive ischiorectal block reduces the posthemorrhoidectomy pain and opioid demand.
