PURPOSE: The purpose of this study was to examine the effects of preceptor nurses' self-leadership on role recognition and job satisfaction. METHOD: The participants were 171 preceptor nurses worked in one of three general hospitals in Seoul. The data were collected from April 12 to May 12, 2011 and analyzed using descriptive statistics, t-test, ANOVA, pearson correlation, Scheffe, and regression with SPSS Win 19.0 program. RESULT: The results of the study were as followed. The average score for preceptor nurses' self-leadership was 3.55, for role recognition, 3.81 and for job satisfaction, 3.28. The factors of the preceptors' self-leadership affecting role recognition were self-expectation (beta=260, p=.002) and goal setting (beta=199, p=.030), and those factors accounted for 18.9% of explanatory power. The factors of self-leadership influencing job satisfaction were self-expectation (beta=18.3, p=.021), and rehearsal (beta=-168, p=.030), and those factors accounted for 31.3% of explanatory power. Among the factors of self-leadership, self-expectation influenced both role recognition and job satisfaction. CONCLUSIONS: The results of the study indicate that to improve preceptor's role recognition and job satisfaction, there should be special training programs to enhance preceptor's self leadership.

Neurofibromatosis is a complex hereditary disease involving many organs and systems. The incidence in pregnancy is less frequent and has been reported as 1/5000 to 1/18500 deliveries. Therefore, little is known about the interactions between neurofibromatosis and pregnancy. A survey of relevant literature suggests that patients with NF have an increased risk of perinatal complications (pregnancy induced hypertension, IUGR, preterm labor, abortion, stillbirth, high cesarean section rate) and maternal disease aggravation (rupture of an aneurysm, sarcomatous degeneration of neurofibroma, activation of pheochromocytoma). Refined ultrasound, flow studies and fetal monitoring allow us to provide improved pregnancy care for neurofibromatosis. However, It should be remembered that even now, neurofibromatosis places pregnant women and their fetuses in a high risk group with the potential to develop life threatening complications. We report a case of vertebral artery aneurysm and preeclampsia complicating a pregnancy with neurofibromatosis."

PURPOSE: With the technical advancement in arterial embolization and subsegmental resection of liver neoplasm, emphasis has been on more detailed knowledge of normal arterial anatomy and its variation. We analysed the patterns of intrahepatic branches of right hepatic artery. MATERIALS AND METHODS: We retrospectively analyzed intrahepatic branching patterns of right hepatic artery in 165 cases. All cases had a single right hepatic artery which could be traced up to tertiary branches, and also performed rapid drip infusion CT scan, hepatic arteriography with antero-posterior and oblique views, superior mesenteric arteriorgraphy and indirect portography. RESULTS: lntrahepatic branching patterns of the right hepatic artery had eight types of variation. The most common intrahepatic branching pattern was type I: 107(64.5%) which represented 5, 8th branch emerging from the anterior segmental artery and 6, 7th branch from the posterior segmental artery. Type VII :26(15.8%) was the next common type which represented 6th branch emerging first from the posterior segmental artery and 7th branch emerging secondly from the posterior segmental artery. Type VII, VI, III were branched from the posterior segmental artery. Type IV, II, V were branched from the anterior segmental artery. CONCLUSION: These result could be helpful to the planning of treatment, such as hepatic subsegmentectomy or transarterial embolization of the hepatic neoplasm.

BACKGROUND: Korea is an endemic area of viral hepatitis B with a rate of 5~10% carrier state. Therefore, hepatitis B vaccination is performed nationwide. But 5~15% of healthy individuals fail to respond adequately to the vaccine and an approved guideline for the nonresponders has not been developed yet. This study is designed to identify risk factors for those who lack anti-HBs after hepatitis B vaccination and to document the results of a double-dose revaccination in such nonresponders to the primary vaccination. METHODS: From Feb. 1996 to Aug, 1997, we assessed 51 healthy subjects(HBs Ag negative, anti-HBs negative, anti-HBc negative and a normal LFT). All subjects were vaccinated with Hepavax- B, 1.0ml, 24 by a rapid schedule(0, 1, and 2 months) and 27 by a standard schedule(0, 1, and 6 months). Anti-HBs titers were evaluated 3 months after the third vaccine and assessed the nonre-sponders (anti-HBs titer<2mIu/ml) and the hyporesponders(2~10mK/ml). All 13 nonresponders were revaccinated with 2ml of Hepavax-B 3 months after the primary vaccination. Anti-HBs titers were evaluated 1 month later. RESULTS: The differences in age(p<0.01) and smoking amount(p<0.05) between the responders and the hypo and the nonresponders were statistically significant. There were more males and higher body mass index in the hypo and the nonresponders but not statistically significant. The seroconversion rate after the double-dose vaccination was 92.3%(12/13) with an average titer of 5K08mlU/ ml(1-132.4mIU/ml). CONCLUSIONS: Increase in age and smoking amount were the risk factors of the nonresponders after the primary vaccination. Most of the hypo and the nonresponders to the primary vaccination responded adequately to the double-dose revaccination.

Left atrial myxoma is well-known mimicker of systemic vasculitis. In general, however, these patients showed some symptoms and signs of cardiovascular disease. We experienced a patient with left atrial myxoma who first presented as vasculitis without any symptoms and signs suggesting cardiovascular disorders. A 45 year-old lady showed tender skin nodules, livedo reticuiaris-like skin lesions, severe constitutional symptoms, multiple cerebral infarctions, and elevated ESR and globulin. Skin biopsy findings were thought to be consistent with polyarteritis nodosa. Echocardiography was performed as a routine test for evaluating suspected vasculitis patients and it revealed left atrial myxoma. However, we were not able to detect any auscultation abnormality, even after echocardiography, After echocardiography, we found the tumor emboli in skin biopy specimen with deeper section. This case demonstrated the importance of suspecting the possibility of left atrial myxoma when performing diagnostic work-up for vasculitis.

An accurate early diagnosis of congenital midgut malrotation is essential to prevention of catastrophic effects of volvulus. To evaluate the usefulness of radiologic examinations in diagnosing intestinal malrotation, we retrospectively analyzed radiologic findings and operation records of 17 intestinal malrotation patients, who were radiologically diagnosed. The age range of the patients studied were from 1day to 12years. The presenting symptoms were vomiting, vomiting with abdominal pain, abdominal distention, diarrhea and failure to thrive. The viewpoints of this analysis were the location of duodeno-jejunal flexure on barium meal and cecal location on barium enema. Sixteen of 17 patients, who were radiologically diagnosed, were surgically proven, but one patient with annular pancreas was false positive. In the case of 3 surgically proved patients, malrotation was suspected on barium meal prior to the barium enema, but final diagnosis was determined on barium enema examination. We concluded that a barium enema should be performed on all children with suspected malrotation where the initial upper gastro-intestinal study was normal or suspicious on account of the small incidence of false positive and false negative barium meals.

PURPOSE: This study was conducted to identify relationships among knowledge and attitudes of unmarried mothers toward emergency contraceptive pills. METHODS: Data were collected through structured questionnaires from 135 unmarried mothers enrolled in 7 single mothers' facilities nationwide. Data were analyzed using the SPSS/WIN 17.0 program for descriptive statistics, t-test, ANOVA, Scheffe-test, and Pearson correlation coefficients. RESULTS: For knowledge about emergency contraceptive pills, there were significant differences among who live with her before pregnancy, experience of past pregnancies, state of present pregnancy and preparation in using contraceptives. For attitude toward emergency contraceptive pills, there were significant differences according to age, education level and religion. There were significant positive relationships between knowledge and attitudes toward emergency contraceptive pills. CONCLUSION: The results of this study suggest that unmarried women should be better informed about emergency contraceptive pills, and reassured about their safety. Efforts are needed to disseminate up-to-date information to experts in sex education including nurses.

Transcranial magnetic stimulation (TMS) is a noninvasive and safe technique for motor cortex stimulation. TMS is used to treat neurological and psychiatric disorders, including mood and movement disorders. TMS can also treat several types of chronic neuropathic pain. The pain relief mechanism of cortical stimulation is caused by modifications in neuronal excitability. Depression is a common co-morbidity with chronic pain. Pain and depression should be treated concurrently to achieve a positive outcome. Insomnia also frequently occurs with chronic lower back pain. Several studies have proposed hypotheses for TMS pain management. Herein, we report two cases with positive results for the treatment of depression and insomnia with chronic low back pain by TMS.
