The purpose of the study was to review ecosystem service researches and show the trend to guide researchers who want to study ecosystem service. Ecosystem service has been a theoretical base for conservation of nature such as grand mountains, rivers and so on. Moreover, reviewed studies showed economical, social, environmental values of ecosystem service in nature as well as in urban to support ecosystem service theory. By leading metropolitan governments in America, Canada and european and asian countries, the urban tree canopy(UTC)s’ ecosystem services have been evaluated quantitatively and accumluated as urban forestry data. This global trend has an implication that the study of UTC and its ecosystem service can support the provision of urban forestry and green spaces and especially, Korean cities should realize UTCs’ values on ecosystem services and start to apply them institutionally to enhance their urban environment.

Neutropenic enterocolitis (NE), the most serious gastrointestinal complication, has been reported as a clinical syndrome that occurs in the setting of disease- or chemotherapy-induced neutropenia. Complications of NE include bowel necrosis with perforation, fistula, stenosis, massive bleeding, abscess formation, and pneumatosis intestinalis (PI). Most physicians recommend initial conservative management with bowel rest, intravenous fluids, total parenteral nutrition, broad-spectrum antibiotics, and normalization of neutrophil counts. Surgical intervention is recommended in the event of obstruction, perforation, persistent gastrointestinal bleeding despite correction of thrombocytopenia and coagulopathy, or clinical deterioration. We experienced a patient whose abdominal computed tomography scan showed pneumoretroperitoneum, intramural gas in the colon, and inferior vena caval gas. Her condition improved after treatment with granulocyte colony-stimulating factor and broad-spectrum antibiotics. We report on this case along with a review of the literature.

‘Taegang’ is a new six-rowed covered barley cultivar developed by the National Institute of Crop Science (NICS), R.D.A. This cultivar is developed from a cross between ‘Suwon287’ and ‘Olbori’ in 1992. An F8 selection was made at NCES in 2000 and it was te
