Near-Drowning 환아의 예후 판정에 대한 초기 Glucose의 의의

To validate the prognostic significance of initial blood glucose level in near-drowning, we have researched the relationship between initial blood glucose level and complications of 21 patients under 15 years with near-drowning, who admitted to the Department of Pediatrics, Chungnam National University Hospital from Jan. 1985 to Dec. 1992. The results were as follows ; 1) In distribution of sex, male was 15 cases and female was 6 cases and male to female ratio was 2.5:1. 2) The most common age group of incidence was under 3 years(8 cases:38.0%) 3) The most common season of incidence was summer(16 cases:76.6%) 4) The mean blood glucose level of subjects was 198mg/dl. 5) The group of prolonged period of submersion was significantly higher initial blood glucose level than short period of submersion. 6) The initial blood glucose level of patients with complications(224.30mg/dl) was significantly higer than patients without complications(157.25mg/dl). The results suggest that initial blood glucose level is one of the important prognostic predictor of near-drowning patients.

Ocean Thermal Energy conversion(OTEC) technology is one of OTEC technology refer to a mechanical system that utilizes the natural temperature gradient that exists in the tropical ocean between warm surface water and the deep cold water, to generate electricity and produce other economically valuable by-products. The selection of working fluid and working conditions of the OTEC’s cycle has a great effect on the system operation, and it’s energy efficiency and impact on the environment.Working fluids of the OTEC is Ammonia, R22, R407c, R410a. Ammonia have a large heat capacity. But, ammonia is difficult to treat. R22 has been proposed as the working fluid instead of ammonia due to toxicity problems, it would be prohibited according to the Montreal Protocol. Therefore, more research is needed on developing more suitable working fluid substitutes. It is a R407c, R410a. In this paper, the optimization of and Ocean Thermal Energy Conversion(OTEC) system is carried out by the Powell method (according to the Workin g Cycle and Working Fluids).
