PURPOSE: The purpose of this study is to verify the factors that determines burnout of nurses in emergency department. METHODS: The survey was given to 170 ED nurses which are located in Busan from July 1st to August 31st of 2012. The results were analyzed by descriptive statistics, t-test, ANOVA, pearson correlation coefficients and stepwise multiple regression using SAS 9.2 program. RESULTS: There were statistically significant differences in burnout depending on gender, position, workplace satisfaction, job satisfaction. Significant positive correlation between compassion fatigue and burnout was found. Also significant negative correlation was found between self-esteem, compassion satisfaction and burnout. Factors influencing burnout were self-esteem, compassion satisfaction and compassion fatigue with R2 value 58.0%. CONCLUSION: Considering these results, it seems that great efforts will be needed for reducing burnout by mitigating the emergency nurses' compassion fatigue and introducing programs to increase the self-esteem and compassion satisfaction.

PURPOSE: This study attempts to examine the effects of a horticultural program on activities of daily living (ADL) and depression among older patients with mild dementia. METHODS: This study adopted a quasi-experimental design-based nonequivalent control group pretest and posttest design, enrolling 30 older patients with mild dementia. The Korean Form of Geriatric Depression Scale was utilized, while the data was collected from the experimental group for 60 minutes, twice weekly for 6 weeks in 12 sessions. ADL and depression were assessed for both the experimental and the control group. Overall functions were assessed only for the experimental group. RESULTS: The experimental group showed improvement in physical function, cognitive function, as well as psychological, emotional function and social function following each session (p<.001). The horticulture program was effective in both ADL (Z²=5.65, p<.001) and depression (t=-5.24, p<.001). CONCLUSION: In this study, the horticultural therapy based on the Cox's interaction model had positive effects for older patients with mild dementia. Therefore, horticultural therapy may be commendably applied to older patients with mild dementia as a nursing intervention.

Because melanocytes are found throughout the leptomeninges, primary melanotic pigmented tumors such as pigmented meningioma, malignant melanoma, melanoblastosis, and melanocytoma can arise from this region. Melanocytomas have been described in the literature as isodense or hyperdense compared with brain parenchyme, as seen on noncontrast-enhanced CT, and as showing relatively homogeneous enhancement. MR imaging demonstrates a high signal on T1-weighted images, and an iso to hypointense signal on T2- weighted images. We report the imaging findings of a melanocytoma that showed hyperdense attenuation on precontrast CT with homogeneous enhancement and hyperintense signal intensity on T1-weighted images and dark signal intensity enhancement on T2-weighted images, and also review the literature.

BACKGROUND: The development and progression of a tumor can be determined by a complex multistep process involving the activation of oncogenes and the inactivation of tumor suppressor genes. The purpose of this study is to investigate the expression of p53, Rb, bcl-2 protein and Ki-67 labeling index in the intrahepatic cholangiocarcinoma. METHODS: We analyzed 36 cases of intrahepatic cholangiocarcinoma obtained by surgical resection. Expression of p53, Rb, bcl-2 proteins and Ki-67 labeling index were evaluated by immunohistochemical study. RESULTS: Expression of p53 protein was detected in 61.1% (22/36) of cholangiocarcinoma. Rb protein loss and overexpression were observed 27.8% (7/36) and 72.2% (29/36) of cholangiocarcinoma. But bcl-2 protein was not expressed. No significant correlation was found between p53, Rb and bcl-2 protein expression and age, sex, gross type, histologic grade, vascular invasion and lymph node metastases. The Ki-67 labeling index was significantly higher in p53 positive group and Rb overexpression group than in p53 negative group (p<0.01) and Rb loss group (p<0.05). There was a positive correlation between p53 protein and Rb protein expressions, but a negative correlation between Rb protein and bcl-2 protein expressions. CONCLUSIONS: The overexpression of p53 protein and Rb protein may be closely associated with cholangiocarcinogenesis, while bcl-2 has a less crucial role in cholangiocarcinogenesis.

The use of resorbable implants has always been attractive to surgeons because there is no need to remove implant ai'ter fracture fixation. Other advantages include decreased load sharing, multi-taskirv ancl no metal toxicity. But the strength and stiffness of resorhable implants are less than those of metallic implants. Therefore, these implants are suitahle for fixation of particular fractwre sites such as cancellous bone and epiphyscs in which shear loads comprise the major strains. The purpose of this experimental study was to determine whether there are changes in mechanical properties and tissue reactions in the polylactic acid (PLA) rod hy surface moditication using plasma coating or hexafluoropropylene (CF3CF=CF2). PLA rods were inserted into the subcutaneous tissue of back and distal femur in rabbits. Rods in subcutaneous tissue were retrieved for material characterization and those in distal femur were ohtained for histologic observation at postoperative 2, 5, 12 and 16 weeks. The results were as follows; 1. The hydrophobicity of PLA surface was successfully ohtained by plasma coating of hexatluoropropylene gas. 2. Thcre is no significant change in tissue reaction. between controi and plasma coating PLA group. 3. The diametral strength and 3-points bending strength of plasma coating groups were higher than those of control group until postoperative 12 wks, but, diminished at postoperative 16 weeks. In conclusion, the plasma coating of PLA rod using fluorocarbon is a reasonable technique to incrcase the surface hydrophohicily and a promising method to delay the reduction of the strength of PLA rod. Further study on thicker plasma coating and Jong term effect including degradation, nsetaholism and excretion of cotated fluorocarhon will be needed.

Diabetes is a rapidly increasing heath care problem all over the world due to increased prevalence during past decade. Diabetic nephropathy develops in 25-30% of patients with type 1 diabetes and is the leading cause of end stage renal disease. Diabetic nephropathy is characterized by persistent proteinuria, decline in renal function, hypertension and increased cardiovascular morbidity and mortality. Early detection of diabetic nephropathy risk is an important goal because early diagnosis and treatment prevent advanced renal damage and other diabetic complications. Increased urinary albumin excretion rate is widely accepted as the first clinical sign of diabetic nephropathy. However, reduced glomerular filtration or hypertension could be the first manifestation in some diabetic patients. We need improved markers and predictors of diabetic nephropathy risk. We report a case of diabetic nephropathy and decreased glomerular filtration rate (GFR) without microalbuminuria occcured in type 1 diabetic patient.
