We report one case of aseptic necrosis of both talus which has developed without any evidence of previous trauma. Aseptic necrosis of the talus is known to occur after any trauma which result in iterruption the blood supply to talus. Atraumatic aseptic necrosis of talus is extremely rarre condition. Some cases of atraumatic aseptic necrosis of talus were repoted by some authers, in whom Garcia described the first case in 1928. Most of the reported atraumatic aseptic necrosis were due to long term steroid therapy for unrelated medical problems and others were related to Alcoholism, Sepsis and Tuber culosis. ln this case we think for it may be caused or contributed by steroid therapy.

The study was designed to observe the correlation between the eating habits and growth development in 1,574 children(3 - 6 years old) in Kyunggi-do and Seoul, Korea. The eating habits and nutrient intake were determined by mini dietary assessment and food frequency questionnaire (FFQ). 35.6% children had been practicing an unbalanced diets. Children with unbalanced diet consumed less amount of protein source foods (meat, fish, egg, soy products), vegetables and fruits and had irregular meal time, but more of them preferred sweet foods (ice creme, cookies) and carbonated drinks as snack compared with children in balanced diet. 24 - 35% children consumed energy, iron (Fe), calcium (Ca), Niacin, Zinc (Zn) less than 75% RDA. Energy intake of children with unbalanced diet was not significantly different from those with balanced diet, but they consumed less amount of niacin, Fe, Ca and Zn than those with balanced diet. By using the relative percentage of standard weight-length-index (WLI), 65.7% children was normal weight, 12.9% was underweight, 13.4% was overweight and 7.9% was obese. However, 11.9% of underweight and normal weight children was so called thin obese since their body fat content was greater than 20%. There were 16.8% underweight in children with unbalanced diet and 12.6% underweight in those with balanced diet. Compared to normal weight, the underweight children significantly consumed less amount of milk and its product, high protein foods, fried foods and fruits, but obese children consumed more high protein source foods (meat, fish, egg, etc) and sweet foods. In conclusion, the eating habits of unbalanced meal was prevalent problem in preschool children which resulting in their health risks. Therefore, it would be needed that new approach for nutrition education to improve eating habits in preschoolers.

Granular cell tumor is an uncommon neoplasm with uncertain histogenesis that rarely occurs in the orbit. Although it is regarded as a benign lesion, one case of malignancy has been recorded. The authors present a case of recurred, infiltrating orbital granular cell tumor in a 39-year-old woman. On light microscopic examination, the tumor cells showed the characteristic findings of granular cell tumor, but there were hyperchromatic and pleomorphic nuclei with unusual mitotic figures, suggesting a malignant nature.

Solitary fibrous tumors (SFTs) most often involve the pleura and also may encompass the peritoneum and nonserosal sites. They occur as solitary encapsulated tumors and pursue a relatively benign clinical course. The usual criteria for malignancy are high cellularity, mitotic activity (more than 4 per 10 high-power fields), cellular pleomorphism, hemorrhage and necrosis as well as infiltrative growth. We report a case of malignant SFT of pleura who presented with an anterior mediastinal mass. Grossly, it was a 10x8x6.5 cm sized, encapsulated and well-demarcated, solid neoplasm with areas of extensive necrosis. Microscopically, parallel or haphazard arrangement of spindle cells with variable degrees of collagenous background were noted. Storiform fascicle formation, hemangiopericytoma-like pattern, and epithelioid cell clusters were often intermingled. Nodular areas with high cellularity and mitotic activity (> or =10/10 HPFs) were scattered throughout the neoplasm, however no definite cellular pleomorphism was encountered. Tumor cells were immunoreactive for vimentin and CD-34, which distinguished them from the mesothelial cells. Electron microscopically, they revealed fibroblastic and myofibroblastic differentiation.

A histopathological study of erythema nodosum-like lesions in Behcet's disease was performed on 55 patients with incomplete and suspect types of Behcet's disease. Relatively common characteristics in histopathology of erythema nodosum-like lesions could be found in the patients with incomplete type of Behcet's disease. The histopathologic findings of erythema nodosum-like lesions in 21 patients with incomplete type of Behcet's disease were as follows : l. A moderate lymphocytic infiltration was found around the blood vessels and the sweat glands in the dermis. In the subcutaneous tissue, besides lymphohistiocytic infiltration, neutrophils were present in significant number in 9 cases (42.9%) 2. Vasculitis of small vessels was found within the periphery of fat lobules in 7 cases (81.0%), Five cases (23.8%) also showed thrombophlebitis. Seven cases (33.3%) showed histiocytic granuloma formation within the fat lobules. Microabscess formation in the subcutaneous tissue was seen in 5 cases (23.8 %), but it was not certain whether this was the charateristic feature.

6.Survey of Oncology Nurses' Awareness of Patient Safety Culture and Nursing Care Activities for Patient Safety.
Asian Oncology Nursing 2014;14(2):119-126
PURPOSE: The purposes of this study were: 1) To describe the level of awareness of patient safety culture and nursing care activities for patient safety and, 2) To identify factors affecting nursing care activities for patient safety among oncology nurses working at inpatient care units. METHODS: The study sample included 221 nurses working in oncology wards. After obtaining IRB approval, data collection was done with structured self-administered questionnaires, from September 13 to October 13, 2013. Data analysis was done using SPSS WIN 18.0. RESULTS: The mean score of awareness of patient safety culture was 3.46 and the mean score of nursing care activities for patient safety was 4.31 both on a scale of 5.0. Significant factors affecting nursing care activities for patient safety were the open attitude of the supervisor toward patient safety (beta=.19, p=.005) and the degree of patient safety within a ward perceived by the oncology ward nurses (beta=.23, p=.003). These factors explained 31% of the subjects' nursing care activities for patient safety (F=6.08, p<.001). CONCLUSION: To increase nursing care activities for patient safety in the oncology ward, a strategy such as an education program for increasing the awareness of patient safety is needed.

Journal of the Korean Ophthalmological Society 2000;41(5):1033-1039
The effects of topical dexamethasone on the endothelial healing and the change of aqueous composition were examined in the repair process of experimental corneal alkali wounds. Corneal alkali wounds were induced, then the eyes were treated topically with either 0.1%dexamethasone or abalanced salt solution[BSS]4 times per day for 8 weeks. Endothelial wound morphometry was performed after alizarin red and trypan blue staining. The concentrations of ascorbic acid, glucose, and the ions, Na, K , Ca2 and Mg2 , were measured in the aqueous humor. Endothelial healing in control corneas showed a biphasic pattern of healing:an initial short-term healing for the first week and then a late long-term healing following a secondary endothelial breakdown. Topical administration of 0.1%dexamethasone deterred endothelial healing during the early period and prevented secondary endothelial breakdown. Total repair process of endothelium was accelerated by the dexamethasone treatment. Among the various components of the aqueous humor examined, ascorbic acid seemed most sensitive to change caused by the alkali injury and dexametha-sone treatment. The present data indicate that dexamethasone may have a therapeutic potential in the management of endothelial healing after corneal alkali injury.

PURPOSE: The purpose of this study was to determine the differences in the level of disease related knowledge, compliance of health behavior, and educational needs in relation to time (at discharge and 6 months after discharge) among patients underwent percutaneous coronary intervention (PCI). METHODS: Data were collected from January 1, 2006 to September 30, 2006 and a total of 60 patients participated in the study. The survey was conducted in patients underwent PCI at the time of discharge right after discharge education was provided and at a follow up visit which was 6 months after discharge. RESULTS: The level of disease related knowledge (p<.001), the compliance of health behavior (p<.001), educational need (p=.496), the sub-item of sexual life (p<.001), follow up (p<.001), diet (p=.021), stress (p<.001) in compliance of health behavior, and the sub-item of specific character of disease in educational needs (p=.015) were significantly different between discharge and 6 months after discharge. CONCLUSION: The results of this study suggested that further education should be provided to the patients underwent PCI regarding medication, smoking cessation, daily life and exercise at a time of 6 months after discharge in order to increase patient compliance of health behavior.

A total of 68 primary melanorna cases diagnosed at Seoul National University Hospital for the past 10 years from 1978 to 1987 were included for this clinico pathological study. Among the 31 primary cutaneous melanomss, 19 cases (61.3%) occurred on hands or feet, especially on the plantar surfaces. The average age of patients with acral melanomas was 49.3 years at the tirne of diagnosis and the male to female ratio of 19 cases was 3.8 to 1. The clinical and histopathologic findings showed that most ecral melanomas, if not all, were the acral lentiginous type. A high incidence of metastasis (73.7%) was recognized in acral melanomas.

Journal of the Korean Ophthalmological Society 2000;41(8):1631-1637
The effects of topical sodium-hyaluronan on the stromal and endothelial healing were examined in the repair process of experimental corneal alkali wounds. Corneal alkali wounds were produced in one eye of each rabbit by applying a 5.5 mm round filter paper soaked in 1N NaOH onto the central cornea for 60 seconds. Then the eyes were treated topically with either 1% Na-HA(the treatment group)or a phosphate buffered saline(PBS)(the con-trol group)4 times per day for 3 weeks. Endothelial wound morphometry was performed after alizarin red and trypan blue staining. The stromal healing was assessed by counting polymorphonuclear leukocytes(PMNs)and keratocytes in the central and marginal wounds areas. The stroma treated with Na-HA had less PMNs than that of the control group during the early healing period. The defect area of the endothelium was significantly smaller in the Na-HA treated group than in the control corneas. The present findings indicate that topically applied 1%Na-HA affects stromal and endothelial healing during the early repair process after corneal alkali wounds.
