PURPOSE: The purpose of this study is to analyze the structural model on the Nursing Task Performance of Hospital Nurses. METHODS: Data collection was done by the 200 hospital nurses from May 1st to May 20th, 2013 in Seoul city. The sample variance-covariance matrix was analyzed using AMOS 19.0 and the maximum likelihood minimization function. The goodness of fit was evaluated using the SRMR, RMSEA and its 90% confidence interval, CFI, and TLI. RESULTS: First, hospital nurses' organizational justice and empowerment was not found to have a significant direct effect on nursing task performance. Second, organizational justice and empowerment had a direct effect on job satisfaction and organizational commitment. Third, organizational commitment was found to have a significant direct effect on nursing task performance. Forth, hospital nurses' empowerment was found to have a significant direct effect on nursing task performance. CONCLUSION: Nurses' nursing task performance was influenced by organizational justice, empowerment, and organizational commitment. In order to increase the degree of nursing task performance in hospital nurse, it is necessary to develop the nursing program and its application considering hospital nurses' organizational justice and empowerment and organizational commitment.

The ornithine aminotransferase (OAT) activity of mouse was found to be highest in the small intestine. The mitochondrial OAT from mouse small intestine was purified to homogeneity by the procedures including heart treatment, ammonium sulfate fractionation, octyl-Sepharose chromatography, and Sephadex G-150 gel filtration. Comparing to the amino acid sequence of mouse hepatic OAT, six N-terminal amino acid residues have been deleted in intestinal OAT. However, the subsequent sequence was identical with that of hepatic OAT. The molecular weights of both intestinal and hepatic OAT were estimated as 46 kDa by SDS-gel electrophoresis and as 92 kDa by gel filtration, indicating that both native OATs are dimeric. Biochemical properties of intestinal OAT, such as molecular weight, pH optimum and K(m) values for L-ornithine and alpha-ketoglutarate, were similar to those of hepatic OAT. However, intestinal OAT was more labile than hepatic OAT to tryptic digestion.

Glucose prevents the development of diabetes induced by alloxan. In the present study, the protective mechanism of glucose against alloxan-induced beta-cell damage was investigated using HIT-T 15 cell, a Syrian hamster transformed beta-cell line. Alloxan caused beta-cell damages with DNA fragmentation, inhibition of glucose-stimulated insulin release, and decrease of cellular ATP level, but all of these beta-cell damages by alloxan were prevented by the presence of 20 mM glucose. Oligomycin, a specific inhibitor of ATP synthase, completely abolished the protective effects of glucose against alloxan-induced cell damage. Furthermore, treatment of nuclei isolated from HIT-T15 cells with ATP significantly prevented the DNA fragmentation induced by Ca2+. The results indicate that ATP produced during glucose metabolism plays a pivotal role in the protection of glucose against alloxan-induced beta-cell damage.

We identified the early and late prognostic factors of acute myocardial infarction, and evaluated the clinical differences and the prognosis between Q-wave myocardial infarction and non-Q wave myocardial infarction. Total 146 patients who were managed from Jan 1987 to Aug. 1989 at hallym University hospital were evaluated. According to the presence or absence of Q wave on electrocardiogram, the patients were divided into two groups : a Q wave myocardial infarction group(QMI) and a non-Q wave myocardial infarction group (NQMI). Among 146 patients 109 patients(74.7%) had QMI and 37 patients(25.3%) had NQNI. The mean age, male to female ratio and serum cholesterol level were similar in both groups. But peak level of CPK was significantly higher in the QMI group than that in the NQMI group(P<0.01). Left ventricular end-systolic dimension and ratio of left ventricular dimension to wall thickness in the QMI group were significantly higher than that in the NQMI group(P<0.01). There were no significant differences between two groups in the incidences of mortality, postinfarction angina and re-infarction. During the in-hospital period female gender, old age(more than 60 years), Killip class at admission, early reinfarction and a history of hypertension were significant prognostic factors. main causes of death during the in-hospital period were ventricular tachyarrthymia, heart failure and cardiogenic shock. The incidences of mortality, heart failure and post-infarction angina during a mean follow-up period of 14 months (6~30months) were same in the two groups. The late prognostic factors were old age(more than 60 years), Killip class at admission, heart failure occured during follow-up period(P<0.001) and a history of diabetes mellitus(P<0.05). The patients with late postinfarction angina had more dilated left ventricular end-systolic demension(P<0.05) and lower fractional shortening(P<0.01) than those of patients without late postinfraction angina. There were no significant difference in long term survival rate between QMI group and NQMI group. Further prospective study should be performed to clarify the short and long term prognosis in patients with acute myocardial infarction treated by reperfusion.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

A 34-year-old male was admitted to our hospital complaining of chest pain. Chest computerized tomography showed pleural effusion and mass in left lower area. After open thoracotomy and mass removal originating from the parietal pleura were done. The mass was pathologically diagnosed as poorly differentiated synovial sarcoma. Synovial sarcoma of the pleura is rare. Herein we report a case of synovial sarcoma of the parietal pleura.

A 43-year-old male was admitted to our hospital complaining of dyspnea and wheezing sound at respiration. He had received esophageal exclusion and esophagogastrostomy due to spontanous esophageal rupture 1-year ago. Chest computed tomography revealed esophageal mucocele like that of mediastinal tumor. Trachea is compressed by esophageal mucocele. The operation was performed by resection of thoracic esophagus through right open thoracotomy. Herein we report a case of a tracheal compression by esophageal mucocele after surgical exclusion of the esophagus.

Sleep disturbance and restless legs syndrome (RLS) among uremic patients is known to be high, but data on the prevalence, clinical significance, and causative factors are limited. A semiquantitative sleep and RLS questionnaire was distributed to 62 chronic hemodialysis(HD) patients. 74.5N had sleep complaints and frequent awakening was the most frequent specific sleep complaints followed by daytime sleepiness. Presence of diabetes mellitus(DM), RLS, depres- sion, high CRP level, low intact parathyroid hormone level, low subjective global assessment score, and short HD duration were associated with more sleep complaints. 58.3N had RLS and presence of DM, low serum albumin level were also associated with more severe RLS. But Kt/V, protein catabolic rate, hematocrit, plasma bicarbonate level, use of erythropoietin and sleep medication were not associated with sleep complaints and RLS. Sleep problems and RLS are comrnon in HD patients and seem to be associated with malnutrition. Presence of DM, de- pression, and RLS are likely to contribute the high prevalence of sleep disturbance.

The prevalence of right-sided infective endocarditis is increasing with a growing number of intravenous drug abusers. A case of right-sided endocarditis is reported in a 18-year-old female heroin addict. Tricuspid valve vegetation, septic pulmonary emboli and staphyloccus aureus in blood cultures are noted. During antimicrobial therapy, she developed remittent fever and skin rash due to vancomycin. After a change of the antibiotic to teicoplanin, she was freed from fever and discharged in an improved condition.
