Dyeing has always had a pressing need for techniques that allow economical pretreatment for color removal in wastewater. The effectiveness of adsorption for color removal from dyeing wastwater has made it an ideal alternative to other expensive treatment options. This study deals with an investigation on four waste resources locally available in dyeing wastewater treatment for color removal. Peat, bentonite, slag and fly ash were utilized for this study and their performance evaluated against that of granular activated carbon. Color of dyeing wastewater was high removed in peat, bentonite and slag except for fly ash. In point of recycling, if waste resources substituted for a valuable adsorbent such as granular activated carbon, peat, bentonite and slag could look forward to an expected economical effect.

Background: The OR(operating room) should provide an optimum environment that is safe for the patient and the working personnel. The air ventilation system of OR has been studied to decrease the contamination of air. We investigated the flow and contamination of the air in OR at our hospital. Method: Cultures in OR were made and the number of bacteria and fungi were calculated. A two-dimensional model for the cross-section of an operation room is developed for the CFD (computational fluid dynamics) analysis. The characteristics of air flow in the empty operation room and in the occupied operation room are calculated by using a CFD program. Results: The current air ventilation system of our hospital does not deliver the clean air to the operating site efficiently in occupied OR. Conclusions: We suggested a new location of air ventilation system which improves air venting with little increase of the cost of equipment.

Coicis Semen is one of the oriental medicine that has been used for the treatment of the disease such as pulmonary abscess, periappendicular abscess and wart since ancient times. However, the mechanism of the action of the drug is not well studied. This study was done to investigate the effects of Coicis Semen on the host defense mechanism. Effects of Coicis Semen on the immune responses were analyzed by measuring the contact gypersensitivity, hemagglutinin, hemolysin and rosette formation, cytotoxicity, and reactive oxygen intermidiates production. As the results, water extract of Coicis Semen administration enhanced the antibodies (hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen. Also Coicis Semen increased the allogeneic immune response in the mouse, showed cytotoxic activity against human leukemia cell line(K562) and decreased the contact hypersensitivity against dinitroflurobenzene. Also administration of Coicis Semen slightly increased NK cell activity and enhanced the production of such reactive oxygen intermidiates as superoxide and hydrogen peroxide from the macrophages in vivo and in vitro. The above results demonstrate that Coicis Semen has enhancing effects on cellular and humoral immune responses against disease.

고등학교 운동선수에서 최대하 treadmill 운동시험시 심폐기능의 변화를 구명하고 운동부하, 운동시간 및 심박수로부터 산소섭취량을 추산할 수 있는 회귀방정식을 유도하고자 15∼18세의 남자 고등학생 운동선수 14명과 비운동선수 16명을 대상으로 하여 Bruce법에 따라 treadmill 상에서 최대 운동능력의 80%에 해당하는 최대하운동을 실시하고 운동전, 운동중 및 운동후에 심박수, 혈압, 분시환기량, 탄산가스생산량 및 산소섭취량을 측정하였으며 운동 전후에 폐환기역학 검사를 시행하였다. 심박수는 선수군에서 안정시의 71.9±1.3회로부터 운동중 178.0±2.0회까지 증가하여 최대심박수의 81.2±2.3%에 달하였고 비선수군에서는 안정시의 81.8±2.4회로부터 182.6±1.1회까지 증가하여 최대심박수의 79.6±2.0%에 달하였다. 선수군의 심박수는 비선수군에 비해 전 실험기간에 걸쳐 유의(P<0.01)하게 낮은 값을 유지하였다. 분시환기량은 선수군에서 안정시의 5.1±0.6 L/min로부터 운동중 63.0 L/min까지 증가하였고 비선수군에서는 안정시의 5.2±0.5 L/min로부터 51.2 L/min 까지 증가하였으며 양군 사이에는 유의한 차이가 없었다. 산소섭취량은 선수군에서 안정시 1.0±0.4 ㎖/㎏/min로부터 운동중 32.6 ㎖/㎏/min까지 증가하여 최대산소섭취량의 72.9%에 달했으며 비선수군에서는 안정시 1.4±0.3 ㎖/㎏/min로부터 28.9 ㎖/㎏/min까지 증가하여 최대산소섭취량의 70.3%에 달하였다. 선수군의 산소섭취량은 비선수군에 비해 계속 낮은 경향을 보였다. Treadmill 속도 및 경사도와 산소섭취량 간의 중회귀분석 결과 중상관계수 0.9998로서 높은 상관관계를 나타내었다. Bruce법에 따른 운동시간과 산소섭취량 간의 회귀분석 결과 1차함수 회귀식에 대한 상관계수는 0.999였으나 3차함수 회귀식에 대한 상관계수는 0.99999로서 극히 높은 상관관계를 나타내었다. 심박수와 산소섭취량 간에는 상관계수 0.998 및 0.992로서 대체로 높은 직선적 상관관계를 나타내었다. 폐기능검사 결과 안정시 FVC, FEF_(0.2-1.2L), FEF_25% 및 MVV는 선수군에서 비선수군에 비해 유의(P<0.05)하게 높았다. 운동후 폐기능검사 성적은 비선수군에서는 안정시보다 저하된 경향을 보인데 비해 선수군에서는 향상된 경향을 보였다. The cardiorespiratory function was evaluated during and after a submaximal treadmill exercise and some regression equations were derived for estimation of oxygen uptake from exercise load, exercise time and the heart rate. A total of 30 high school boys, of whom 14 were athletic and 16 non-athletic, performed a submaximal treadmill exercise according to the Bruce protocol to the point when 80% of their maximum exercising capacity were reached. The heart rate, blood pressure, minute ventilation, CO_2 production and O_2 uptake were measured before, during and after exercise, and the pulmonary function test was performed before and after exercise. Heart rate was increased from 71.9±1.3 beats/min at rest to 178.0±2.0 during exercise which was 81.2±2.3% of the maximum heart rate in athletes, and from 81.8±2.4 beats/min at rest to 182.6±1.1 which was 79.6±2.0% of its maximum in non-athletes. Athletes showed significantly (P<0.01) lower heart rate than non-athletes throughout the experimental period. Minute ventilation was increased from 5.1±0.6 L/min at rest to 63.0 in athletes and from 5.2±0.5 L/min to 51.2 in non-athletes. Athletes and non-athletes showed no significant difference. Oxygen uptake was increased from 1.0±0.4 ㎖/㎏/min at rest to 32.6 which was 72.9% of maximum oxygen uptake in athletes, and from 1.4±0.3 ㎖/㎏/min to 28.9 which was 70.3% of the maximum in non-athletes. Athletes showed consistently lower oxygen uptake than non-athletes. Multiple regression analysis between treadmill speed and grade and the oxygen uptake showed a high correlation coefficient of 0.9998. A first order regression analysis between exercise time and oxygen uptake showed a correlation coefficient of 0.999, while a third order regression analysis showed an extremely high correlation coefficient of 0.99999. The heart rate and oxygen uptake showed a linear regression with a reasonably high correlation coefficient of 0.998 and 0.992. The pulmonary function test revealed significantly(P<0.05) higher FVC, FEF_(0.2-1.2L), FEF_25% and MVV at rest in athletes than in non-athletes. After exercise, athletes showed enhanced pulmonary function compared with the resting state while non-athletes showed more or less decreased.

裵玉錫,黃樹寬,金亨鎭,朱永恩 慶北大學校 醫科大學 1982 慶北醫大誌 Vol.23 No.2

20∼22歲의 男子大學生 61名을 硏究對象으로 하여 選手群(21名)과 非選手群(40名)으로 區分하였다 運動負荷는 rebouner에 垂直뛰기를 一分間에 80回程度로 3分동안 實施했으며, 運動後 恢復期 1, 3, 5, 10 및 20分에서 心搏數, 血壓, 呼吸數의 恢復樣相을 觀察하였다. 이로써 체력단속이 恢復期의 心肺機能에 미치는 影響을 分析하고 나아가서 恢復期의 心肺反應이 體力을 評價하는 指標가 될 것인가를 알고자 試圖한 本 硏究結果를 要約하면 다음과 같다. 安靜狀態의 心搏數는 選手群이 非選手群에 比해서 有意하게 낮았으며 血壓 및 呼吸數는 別 差異가 없었다. 運動負荷後 心搏數의 恢復은 選手群은 恢復 1分에 86.4±3.22回로서 非選手群의 118.0±2.81回에 比해 有意하게 낮았고, 兩群 모두 恢復初期에는 急速한 恢復을 보였으며 選手群이 非選手群에 比해 繼續有意하게 낮은 값으로 빠른 速度로 恢復되었다. 運動負荷後 收縮期血壓의 恢復樣相은 選手群이 非選手群보다 繼續 낮은 값으로 恢復되었으며, 特히 恢復 1分에 選手群은 161.2±1.78mmHg로 非選手群의 174.1±3.41mmHg에 比해 有意하게 낮았다. 兩群 모두 恢復初期에 急速히 恢復하여 恢復10分에는 安靜狀態로 恢復되었다. 그리고, 擴張期血壓은 非選手群은 期動後 安靜狀態보다 有意하게 높았으며, 選手群은 오히려 安靜狀態보다 낮았다. 平均動脈壓은 恢復初期에 選手群이 非選手群보다 높은 값으로 恢復되었으나 恢復10分부터는 거의 같은 값으로 恢復되었다. 脈壓은 選手群이 非選手群에 比해 繼續 有意하게 낮은 값으로 恢復되었다. 運動負荷後 呼吸數는 恢復 1分에 選手群에서는 27.1±1.23回로 非選手群의 35.5±1.17回에 比해 有意하게 낮았고, 兩群 모두 恢復 1,3分에 急速히 恢復되었으며, 選手群이 非選手群에 比해 繼續 有意하게 낮은 값으로 恢復되었다. 本硏究結果를 綜合하면 rebounder 運動負荷後 選手群의 心搏數, 血壓 및 呼吸數가 非選手群에 比해 有意하게 낮았으며, 그 恢復速度도 빨랐다. 특히 心搏數는 選手群과 非選手群 사이에 恢復初期부터 恢復 20分까지 繼續 有意한 差異를 나타낸 점은 體力을 客觀的으로 評價하는 重要한 資料가 될 것으로 思料되는 바이다. Sixty-one male subjects aged between 20-22 years were divided into the athletic and non-athletic groups. Exercise was performed as vertical jump on a rebounder at 80 times per min for 3min. The heart rate, blood pressure, and respiratory rate were measured at 1, 3, 5, 10, and 20min after exercise in an effort to analyze the effect of the physical training on the cardiopulmonary function during the recovery period, and to find out if the cardiopulmonary responses during recovery period can be an index of physical fitness. The results are summarized as follows. In resting state, the heart rate was significantly lower in athletes than in non-athletes, while blood pressure and respiratory rate showed no significant difference between the two groups. The heart rate at 1min after the exercise was 86.4±3.22 in athletes which was significantly lower than 118.5±7.85 in non-athletes. The heart rate at the initial stage after exercise showed a rapid recovery in both groups. In athletes, it showed a rapid recovery to reach a significantly lower level than that of non-athletes. The systolic pressure was lower in athletes than in non-athletes throughout the recovery period. In particular, systolic pressure at 1min after the exercise was 161.2±1.78 mmHg in athletes which was significantly lower than 174.1±3.41mmHg in non-athletes. Systolic pressure at initial stage after the exercise showed a rapid recovery, and the resting value was retored in 10 min in both groups. Diastolic pressure during the recovery period was significantly higher in non-athletes and lower in athletes than the resting level.
