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.

본 논문에서는 동력학적 특성이 좋은 PLCM을 이용한 256비트 길이의 암호 키와 32비트 데이터 블록의 카오스 블록 암호화 기법을 제안한다. 본 논문에서 제안한 기법은 256비트의 키에서 각 암호화 단계마다 사용될 32비트의 세션 키 두 개를 생성해서 PLCM의 초기 값과 반복회수를 결정하는데 사용한다. 본 제안 기법은 피드백 구조와 대치 기능의 S함수를 통해 암호 강도를 향상시켰다. 또한 실험 결과와 안전성 분석을 통해 본 제안 기법이 통계적(Statistical) 공격에 매우 강함을 보여준다. In this paper, we propose a chaotic block encryption scheme using a PLCM (Piecewise Linear Chaotic Map) having a good dynamical property. The proposed scheme has a block size of 32 bits and a key size of 256 bits. In the proposed scheme we use two 32-bit session keys generated from 256-bit key to decide the initial value and the number of iteration of PLCM. To enhance the strength of security we use a feedback structure and a S (Substitution) function. With results of test and analyses of security we show the proposed scheme is very secure against statistical attacks.

소라의 呼吸에 미치는 溫度 및 明·暗의 影響을 究明하고 週期性과의 關係를 調査한 結果는 다음과 같다. 1. 소라의 酸素消費는 晝夜에 따라 週期性을 나타내었는데 日沒 2時間 後에 酸素消費量이 가장 높았다. 2. 溫度에 따른 酸素消費量은 10∼25℃의 範圍에서 增加하였고 30℃ 에서 減少하였다. 3. 明·暗에 따른 酸素消費量의 크기는 常溫(20∼25℃)에서 自然條件 馴化群, 暗馴化群, 明馴化群의 順이었다. 4. 明 및 暗馴化群의 酸素消費量은 10℃의 경우보다 30℃에서 현저한 減少를 나타냈다. 5. 溫度 및 明暗의 영향은 두 群 사이에 서로 비슷한 傾向을 보였다. The effects of temperature, light and dark for the respiratory rate and the periodic oxygen consumption of the topshell, Turbo cornutus SOLANDER was measured. The oxygen consumption patterns showed circadian rhythms which increased form sunset to midnight and decreased form midnight to midday. The highest value of respiratory rate was appeared in about 2 hours after the sunset. In the temperature range of 10∼20℃, the oxygen consumption increased with the increase of temperature, but markedly decreased at 30℃. The oxygen consumption in the animals acclimated to natural condition under 20∼25℃ water temperature was superior to the light and dark condition, respectively. The oxygen consumption in the animals acclimated to light and dark condition were significantly decreased at 30℃ than 10℃ water temperature. The effects of temperature and light condition for respiratory rate was appeared similarly between A and B groups.

The calorific content change in the gonad and meat of topshell, Turbo cornutus SOLANDER was observed from April to October 1978, with references to determination on the changes of calorific value in the meat and the gonad of topshell. The changes of the condition factor and the gonad maturity were closely related to water temperature, the former was highest in August and the latter was in July, but their value were markedly declined during the spent periods of topshell. The calorific value in the meat and gonad of topshell were highest in July, befor spawning and lowest in August , spent period of topshell. The calorie used for gonad development of female and male were 19.8∼29.2% and 12.8∼17.4% of the growth energy, and calorie used for spawning were 41.0% and 60.4% of the growth energy, respectively.

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%.

An induction of spawning by irradiated seawater with ultraviolet rays carried out in the laboratory to conduct fundamental studies on artificial spawning of some cultivated shells, i. e. Haliotis discus, Haliotis diversicolor superlexta, Turbo cornutus, Tapes variegata. Cyclina sinensis. The materials collected from Seongsan-po and Chuza-do during the spiwning season of these species. Stimulus methods for artificial spawning in this experiment were three methods ; UV-rays irradiated seawater used only, the UV-rays irradiation after temperature trestment and UV-rays irradiation after exposure to air. The rate of response and the time required for spawning on the amount of irradiation were observed. In an attempt to artificial spawning by irradiated seawater with UV-rays on the 5 species of shells, the rate of response for spswning in H. discus and H. diversicolor supertexta were effective to induce spawning but weren't in C. sinensis and T. variegata. The most effective discharging time was 4 hours after UV-rays irradiation. As for the amount of stimulus, it was obvious that the spawning rate increased with the amount of the irradiation and reduced the time required for initial spawning. UV-rays irradiation after temperature treatment and UV-rays irradiation after exposure to air were more effective than stimulus by UV-rays irradiated seawater used only. An ability of irradiated seawater caused spawning mediated by photochemical reactions in seawater depending on the enzyme catalyzing oxidative synthesis of prostaglandin. In this experiment, the results suggest that the effect of irradiated seawater with UV-rays to induce artificial spawning is to be recognition.
