PURPOSE: The purpose of this study is to investigate the impact of job stress, self-efficacy and empowerment of 119 Emergency medical technicians in Jeollanam-do. METHODS: This study used the data collected from 346 respondents working for first aid in a fire station. To answer research questions, this study employed frequency analysis, reliability test, F (t)-test, ANOVA, Scheffe' post-hoc test, and multiple-regression analysis. RESULTS: In terms of demographic characteristics, marital status and age had significant impact on job stress, but sex and education did not. In terms of job characteristics, first placement, rank, and tenure made significant difference on job stress, whereas certificate, department, and area did not. These results address that general characteristics, self-efficacy and job stress are critical variables on empowerment. CONCLUSION: From the research findings, it is concluded that fire fighters' job stress can be reduced if professional development programs are given to them, which is likely to provide better public services such as first aids and welfare, as well as to increase job satisfaction.

The ability of several species of streptococcus and staphylococcus to adhere to human buccal epithelial cells was studied in vitro by using bacteria and epithelial cells isolated from human buccal cavity. Viridans streptococci were found adhering in highest numbers(65 +/- 8 bacteria per epithelial cell) to epithelial cells. Streptococcus pyogenes adhered in great numbers (44 +/- 4), whereas Streptococcus pneumoniae (26 +/- 2), Staphylococcus aureus (21 +/- 2), Staphylococcus epidermidis (14 +/- 2) adhered poorly. These data showed that bacteria differed in their ability to adhere to human buccal epithelial cells. This difference in adhesive ability between bacterial species may correlate with the ability of the bacteria to colonize oral surface of human.

A 61-year-old man presented with chest pain and ST elevation, and he underwent coronary angiography under the impression of acute myocardial infarction. Coronary intervention under intra-aortic balloon pumping was necessary due to his hemodynamic instability from the acute total occlusion of a large obtuse marginal branch. In spite of successful intervention, the cardiogenic shock persisted, and so extracoporeal membranous oxygenation was performed to treat this. Afterwards, the cardiogenic shock still persisted, and the auscultatory and echocardiographic findings revealed severe acute mitral valve regurgitation. Emergency mitral valve replacement was then performed. The ECMO and IABP were removed on the 2nd postoperative day. The patient was discharged on the 48th postoperative day.

The Brunner's gland adenoma is characterized by a nodular proliferation of histologically normal Brunner's gland, accompanied by ducts and scattered stromal elements. First descrived by Salvioli in 1876, the tumor is relatively rare, with 119 cases reported by 1977, The most common benign tumor of the small bowel is the adenoma, 25% of which occur in the duodenum. They make up 30% to 50% of all hyperplastic polyps of the duodenum. Most frequently these tumors are discovered in patients in the fourth to sixed decades of life, though the age in reported caes ranges from l 1 days to 80 years. The benign tumors of the duodenum 30% to 50% contain elements of Brunner's gland and 10.6% of them are adenomas of Brunner's gland. We report a case of Brunner's gland adenoma treated by endoscopic polypectomy in 63 year-old woman, and reviewed the literatues of adenoma of the Brunne'r gland.

Hypermobility of the bladder neck in response to increased intraabdominal pressure is the anatomical cause of female stress urinary incontinence ( SUI) and the degree of bladder neck movement has been used to classify SUI patients and to guide management decisions. We performed transvaginal ultrasonography in 14 SUI patients and 20 normal female as control to assess its role on the demonstration of the anatomical features associated with SUI. We adopted three anatomical factors in the sagittal plane which affect the bladder neck mobility , vertical (JY) and horizontal(JX) distance difference between pubic symphysis and bladder neck, and rotation angle difference(JZ) composed of by pubic symphysis and bladder neck during rest and stress states. There were significant differences in Y and Z between the two groups. Three months after corrective surgery for SUI these two factors showed significant improvement in all patients. It could be concluded that transvaginal ultrasonography is a safe and reliable method to diagnosis and evaluate the postoperative outcome for SUI.

PURPOSE: We evaluated predictive risk factors affecting the long-term efficacy of the tension-free vaginal tape(TVT) procedure for the treatment of female stress urinary incontinence(SUI). MATERIALS AND METHODS: We included 138(mean age 52.4+/-9.3) women who underwent the TVT procedure and followed up for at least 5 years. We analyzed parameters including patient characteristics, history, physical examination, 1-hour pad test, and urodynamic studies using univariate and multivariate analyses with respect to the cure rates. The patients were regarded as cured in the absence of any episodes of involuntary urine leakage during stressful activities and stress cough test. RESULTS: The overall 5-year cure rate was 76.8%, with an 86.9% patient satisfaction rate. On univariate and multivariate analyses, there were no significant parameters affecting the cure rate. The urgency negatively impacted patients' satisfaction(p=0.017, OR=4.114). According to the subgroup analyses, cure rates were lower in patients with high body mass index(BMI=25 kg/m(2), 68.3% vs 83.3%, p=0.044), lower Valsalva leak point pressure(VLPP<60 cmH2O, 51.6% vs 82.8%, p=0.003), and high-grade incontinence(40.0% vs. 69.7%, 86.6%, p=0.012). CONCLUSION: the TVT procedure is an effective and safe surgery for SUI without any independent predictive factors affecting long-term cure execept urgency affecting satisfaction. However, higher BMI, low VLPP and high- grade incontinence may impair the efficacy of the TVT procedure.

PURPOSE: This study aimed to evaluate the ultrasonographic findings for various types of vascular closure devices (VCDs) immediately after the angiographic procedure and at 6-month follow-up. METHODS: We included 18 VCDs including Angio-Seal (n=4), FemoSeal (n=8), ExoSeal (n=3), Perclose (n=2), and StarClose (n=1) in this study. Four patients were implanted with 2 VCDs at the each side of bilateral femoral arteries, while the remaining 8 patients were inserted 1 VCD at the right femoral artery. Ultrasonography was performed within 10 days and at approximately 6 months after the angiographic procedure. Ultrasonographic morphology of the attached VCD and its relationship with the arterial wall were analyzed. RESULTS: Initial ultrasonography revealed the attached VCD as the relevant unique structure with successful deployment and hemostasis. Follow-up ultrasonography demonstrated partial absorption of hemostatic materials in cases of Angio-Seal (n=3), FemoSeal (n=5), and ExoSeal (n=3), changes in the soft tissue surrounding the femoral artery in case of Angio-Seal (n=1), arterial intimal hyperplasia in cases of FemoSeal (n=3), and no gross changes as compared with the initial ultrasonographic findings in cases of Perclose (n=2) and StarClose (n=1). CONCLUSION: Initial ultrasonographic evaluation reflected the unique structure of each VCD, with most of them being easily distinguishable. Follow-up ultrasonography revealed various changes in the affected vessels.
