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.

Infantile hemangioendothelioma of the liver is a common vascular tumor in infancy. The tumor is usually multinodular or diffuse and classified into two types. We present a case of infantile hemangioendothelioma of the liver, which predominantly consists of type 2. A 4-month-old female was admitted for an evaulation of an abdominal distension. A CT scan of the liver showed a multinodular mass. The right lobectomy was done. Grossly, the mass consisted of round nodules ranging from 2cm to 5cm in diameter. Microscopically, the tumor revealed proliferation of small vascular channels lined by endothelial cells. Bizarre cells and mitotic cells were frequently noted. Vesicular nuclei and multilayering of the endothelial cells were also noted.

BACKGROUND: Skin thickness for parameter of skin aging has been analysed with various methods. Skin thickness variations between the young and the old has been studied with various methods such as biopsies, calipers, micrometers, computer tomography, ultrsonography. But none of these methods evaluates skin thickness exactly. OBJECTIVE: For the evaluation of age-dependent skin thickness changes, we compared the skin thickness of an old-aged group and a young group with 20MHz-ultrasonography. METHODS: In order to identify the skin thickness variation between different age groups, 60 subjects, 30 aged 23-33, and 30 over 60, were studied with 20MHz-high frequency ultrasonogrphy (Dermascan C, Cortex Technology, Hadsund, Denmark) on fourteen skin sites. This machine was designed to measure the thickness from the top of the epidermis to the bottom of the dermis. After storage of cross-sectional skin imaging, skin thickness was calculated with a computer assisted image-analysis program. Skin thickness of the old was analysed by age, sex, height and weight.

We are reporting a case of 25-year-old male patient with elastosis perforance serpiginosa who showed multipte serpiginous plaques on his neck. Some of the lesions showed hypopigmented, hard, scar-tissue like plaques in the central part. Histologic examination showed hyperplasia and transepidermal elimination of elastic tissue. By electron microscopy, also, we could prove that the elastic fibers were increased in the dermis.

Propyl gallste and other gallic acid esters are used as antioxidants in lipsticks, lip balms and salves, cosmetic creams and lotions, bakery products, edible fats and other pharmaceutical and industrial products. Propyl gallate is used widely but allergic contact dermatits from propyl gallate is rare. A 44-year-old female patient had pruritic multiple tiny erythematous papules and vesicles on the margin of her lip for a week. We found that the causative material of the allergic contact cheilitis was propyl gallate. We proved it with a patch test, provocation use test and quantitative and qualitative analysis of the lipstick. To our knowledge, this is the first case report of lipstick allergic contact cheilitis from propyl gallate in Korean literature.

PURPOSE: The physiologic mechanism of chemotherapy induced emesis is poorly understood, but recently it is thought to be mediated by serotonergic (5-hydroxytryptamine-3 or 5-HT3) receptars. 5-HT3 is released by enterochromaffin cells in the gastrointestinal tract, which peaks 2-6 hours after the start of chemotherapy. In this study, the granisetron, an antiemetic agent, was given over 2-hour from the start of cisplatin administration to synchronize the peak level of the drug with that of 5-HT3 release. MATERIALS AND METHODS: Chemotherapy-naive patients undergoing their first cycle of cisplatin ( > 60 mg/m)-based chemotherapy were included. One milligram of granisetron was given intravenously 15 minutes before the start of cisplatin as a loading dose, then 2 mg was given over 2-hour starting with the cisplatin. RESULTS: 24 of 25 patients were evaluable for efficacy and safety. Fifteen (62.5%) of the 24 evaluable patients had advanced gastric carcinoma and 21 (87.5%) received FP (5-FU/ Cisplatin) combination chemotherapy. The complete response rate for acute and delayed vomiting/retching was 58.3% (10/24) and 33.3% (8/24), respectively. The median latency time to first vomiting or retching was 20.3 hours. Side effects were tolerable, but central nervous symptoms (dizziness, headache, or anxiety) and diarrhea were frequently noted. CONCLUSION: Two-hour infusion of granisetron with the beginning of cisplatin showed no superior efficacy compared with historical controls that used bolus administration of granisetron, but somewhat more frequent central nervous system and gastrointestinal symptoms were observed.

OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

BACKGROUND: Total intravenous anesthesia(TIVA) with various kinds of sedatives and synthetic analgesics has many advantages such as no air pollution, no hepatic or renal toxicity and good postoperative pain relief compared with inhalation anesthesia. METHODS: TIVA with fentanyl and propofol was applied to the 25 patients in ASA class I and II. The changes of hemodynamics, arterial blood gas, blood sugar level, hepatorenal function and complications were evaluated perioperatively. RESULTS: Systolic blood pressure and mean arterial pressure decreased after induction, but intraoperatively systolic blood pressure became preoperative value while mean arterial pressure increased compared with preoperative value. Heart rate increased after induction and intraoperatively. At recovery room there were no clinically significant changes in the data of arterial blood gas. The blood sugar level slightly increased during postoperative period. There were no clinically significant changes in hepatic or renal function test of postoperative 3rd day compared with preoperative one. The chief complications of TIVA during anesthesia were pain on injection site and slight movement, while nausea or vomiting, dizziness and urinary retention were the major complications at postoperative period. CONCLUSIONS: TIVA with fentanyl and propofol is considered to have good controllability and it can be applied as one of the general anesthesia methods in the case of contraindications to N2O and volatile anesthetics, but further study will be required to quantify the appropriate dosage of propofol or fentanyl to minimize perioperative hemodynamic change and respiratory depression.

Journal of the Korean Radiological Society 2002;46(1):87-91
PURPOSE: To investigate the incidence of breast arterial calcification in Korean women, and to determine its association with systemic diseases and carotid arterial atherosclerosis. MATERIALS AND METHODS: One thousand seven hundred and thirteen female subjects who underwent mammography at a health care center between May 1999 and May 2000 were included in this study. Of the total, 172 were found to have breast arterial calcification, and were classified according to age. The coincidence of hypertension, diabetes mellitus and hyperlipidemia was examined in both the subject group and the control group selected on the same age basis. To investigate the presence and degree of carotid atherosclerosis, sonographic maging was performed and the findings were compared between the two groups. RESULTS: The incidence of breast arterial calcification showed statistically significant differences according to age, with a higher incidence in older patients (p<0.05). However, there was no statistical difference in the incidence of hypertension, hyperlipidemia, and diabetes mellitus between groups. Carotid atherosclerosis was subjects more prevalent among subjects than in the control group (p<0.05), though there was no statistically significant difference in the degree of luminal stenosis. CONCLUSION: The most common pathologic cause of breast arterial calcification is arteriosclerosis. Breast arterial calcification is demonstrated at mammography, along with other clinical risk factors for atherosclerosis or coincidental neurologic symptoms. We stress that further evaluation of the carotid artery is necessary.
