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.

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.

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.

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.

PURPOSE: To evaluate the frequently of low ahetenuation area in enhanced CT scans of non-Hodgkin lymphoma(NHL) and to find out if there is any pertinent relationship between this and the histopathologic classification. MATERIALS & METHODS: The authors reviewed CT scans in the newly diagnosed 53 patients with NHL. We defined the-low attenuation area as the one with CT attenuation value lower than that of the muscle, surrounding lesion, or other lymph nodes after contrast enhancement. NHL with the low attenuation areas were correlated with the histopathologic findings according to the classification based on the Working Formulation and the frequency of the lesion was evaluated. RESULT: Of the 53 patients, the low attenuation area was found in 13 patients (25%) at CT. The histopathologic classification could be made in 12 patients, among whom one patient was classified as low grade, six as intermediate grade, and five as high-grade. Concerning the specific cell typing, the diffuse large cell type was most common in intermediate-grade NHL seen in five patients and the large cell, immunoblastic type was most common in high-grade NHL seen ih three patients. CONCLUSION: The authors concluded that the low attenution area within lymphoma is not an infrequent finding at CT, and there was no stastistically significant correlation between this finding and the prognostic grading of the Working Formulation.

Parosteal lipoma is a rare and generally asymptomatic benign tumor of mature adipose tissue that is located in direct apposition to the external surface of the bone. These tumors are occasionally associated with reactive changes in the underlying bone. The reactive bone formation is generally restricted to the base of the tumor, that is, near the periosteum. We recently experienced a case of parosteal lipoma in the proximal femur, which displayed exuberant bone and cartilage formation, and this led us to a misdiagnosis of chondroblastic osteosarcoma on the initial biopsy. We report here on this case with a special emphasis on making the differential diagnosis from osteosarcoma.
