Background : Arterial blood gas analysis is the most comon exam in intensive care unit. In this study, the frequency of blood gas analysis and the amount of blood loss after Blood Gas Analysis in Intensive Care Unit were observed. Methods : From November 1999 to February 2000, 115 patients admitted to intensive care unit at Soonchunhyang university Kumi hospital were studied prospectively for the frequency of blood gas analysis and the amount of blood loss after blood gas analysis in Intensive Care Unit. Results : The mean value of frequency of blood gas analysis was 6.41±6.49 and the mean value of amount of blood loss after blood gas analysis was 0.78ml. This was lower than that of other foreign reports. The patients with ventilator therapy above 24 hours showed higher frequency of blood gas analysis than that of not applied ventilator patients. Pulse oxymetry was applied to all patients and the frequency of blood gas analysis was decreased due to the use of strict pulse oxymetry. Conclusion : Doctors and nurses in intensive care unit keep in mind that adequate blood sampling is needed for the decrease of blood loss. Education and protocol for the decrease of blood loss after arterial blood gas analysis may be necessary.

Craniofacial hyperhidrosis patients complain discormfort due to excessve sweating of head and face. Medical treatment has been used but it's effect is transient and side effects are very common. After introducing of video thoracoscope in 1986, many thoracic surgical procedures have been developed using video thoracoscope. But domestic papers about craniofacial hyperhidrosis have not been existed yet. This study analyzed the effect and patient's satisfaction of T2 symoathicotomy. The degree of sweating change of pre and post T2 sympathicotomy and compensatory hyperhidrosis using linear analogue scale in 15 craniofacial hyperhidrosis patients were analyzed. Craniofacial sweating disappeared after T2 sympathicotomy and patients' satisfactions were high. Compensatory hyperhidrosis appeared on trunk, back, abdomen, thigh and buttock but it's degree was not severe. Therefore T2 sympathicotomy is effective and safe method in treatment of craniofacial hyperhidrosis. But further evaluations are needed on more patients, long time follow-up and compensatory hyperhidrosis.

Studies on the growth of topshell which had tagging liberated and ecological survey were taken from the three culturing topshell farms of the Seogwipo coast from June to December, 1977. Three culturing topshell farms are Supseom, Bomokri and Beophwanri coast. The culturing topshell farms are shallow with the mean depth 5~8m, and vertical changes of water temperature and specific gravity in each arears were not appeared. The water temperature of Supseom area was lower than the other areas. The compositions of submarine geological type in Supseom, Bomokri and Beoph-wanri area were B (Hole type) and C (crevice type) type, A (Rock type) type, and C and D (Sand type) type respectively. The Current speeds of each culturing farm area were in the range of 1~20cm/sec, and the current of Beophwanri culturing farm area was slower than the other areas. The absorption "coefficient of Seogwipo coastal water was in the range of 0.218-0.329 and the mean was 0.283. Fifty species of marine algae were identified. Major algal group of each culturing farms were Sargassun sp., Ecklonia, cava, Chladophora sp., calcareous algae. Particularly. Beophwanri culturing farm was abundant in Saragassun sp. Of the three culturing topshell farms increment in growth of topshell were showed rapid growth from June to October and noted that increment in growth of Bomokri was the highest. During the tagging liberated period , the number of spines on newly formed parts of shell was in the range of 0~5 spines. The creeping distance was 5~25m in each culturing topshell farm in all.

In general, the productivity of fisheries products express by weight. Therefore determination of weight of aquatic animals is necessary in many experimental studies, But a shell products including bivalves are contain a lot of water in shell valves, it is impossible to estimate correctly their weight. Water adhering to aquatic organisms results in an overestimate of fresh weight, many different methods have been used to remove the adherent water before weighing. In this paper, model by biostatistics method try to determination of weight of shell-fish, hard clam. The relationship the total weight(TW) on the shell length(SL) showed exponential curve, MW = 0.5186+0.0511 SL2.8840 The relationship dry weight (DW) on the shell lenght (SL) is DW = -0.1150+0.0083 SL2.8840 and the relationship water weight(WW) on the shell lenght(SL) is WW = 0.3243+0.0860 SL2.8840 Another approach for measureing fresh meat weight of aquatic animals is done gravimetrically with a spectrophotometric estimate of adherent water providing a correction for adherent water. The determinations of weight by this fresh meat weight method gave not significant difference on the regression analysis between fresh meat weight and meat weight (directly determined). On the other hand, rate of water weight of hard clam was 28.5%, and the rate of water content was 86.2%.
