A waste water pollution. method is usually divided into the two general method; physical treatment method and chemical treatment method. The coagulation is the chemical treatment method sedimenting particles by the coagulant. It is very important process in separating solid-liquid phase. Therefore, considering organic compound in waste water, the experiment was studying the effect of albumin on flocculation in kaolin suspension by choosing albumin for organic compound and aluminum sulfate for the coagulant. The investigation was carried out to study the comparison of coagulation effect in kaolin suspension +Al_2(SO_4)_3 solution, kaolin suspension + albumin solution, and kaolin suspension+Al_2(SO_4)_3 solution+ albumin solution. The results are as follows ; 1) When Al_2(SO_4)_3 solution only was added to kaolin suspension, it was the most effective among three suspensions. 2) When Al_2(SO_4)_3 solution and albumin solution were added to kaolin suspension, the coagulation effect was very poor than only Al_2(SO_4)_3 solution was added. 3) When albumin solution added to kaolin suspension, it was the most ineffective among three suspensions. Also, with increasing particles, size in kaolin suspension, gravity sedimentation slightly appeared within the range of sensitive action, but within the range of protective action above optimal albumin concentration, it greatly appeared. The optimal albumin concentration increases with increasing particle size and the range of effective albumin concentration for coagulation of kaolin suspension also became wider for 12 hrs. 4) In three suspensions, an equation was obtained between relative turbidity and settling time the following: log τ_rel = -m log t + log c' 5) Considering the aspects of effect of pH on coagulation of kaolin suspended in water, as acidity increased, coagulation effect. gradually increased and also as alkalinity increased, coagulation effect greatly decreased and then, irrespective of pH, coagulation effect increased by gravity sedimentation.

강태훈,안재철,강병희 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.2

To maintain serviceability of concrete structure more than proper it is necessary not only predict service life through periodical monitor but also need monitoring system to recognize optimal time and method for repair. Recently, CPGFHP, replacing some GFRP with CF, is developed and used for monitoring concrete fraction. But dramatic resistance change of CPGFHP is showed below 0.5% strain and it is not small strain in terms of monitoring micro crack in concrete. In other word, monitoring with CF is not suitable in low stress but hight stress. In this study, we accessed applicable possibility and reliability of CPGFHP composite as monitoring sense that is proved very sensitive to stress through domestic and oversea previous study. CPGFHP composite plays a role in specimen like steel and increases flexural strength. CPGFHP composite shows resistance increasement in micro crack. In particular, CPGFHP is more sensitive than strangage in low stress. Resistance change ratio curve is very similar to strain curve so sensitivity and reliability is very excellent to monitor concrete fracture.

This study is a literature review on a research on efficiency of healthcare field with application of DEA(Data Envelopment Analysis). For this, it collected 31 pieces of prior researches at home and abroad on the healthcare field, and analyzed subject(decision-making unit), variables(input variableㆍoutput variable), and analytical model(methodology), which are three kinds of the preceding determinants, according to general process of DEA. As a result of analyzing, the prior researches were performed the medical institution-based efficiency evaluation in the aspect of subject. A segmented effort is needed targeting clinic and unit, which demand independent role, different medical-care pattern, and separately professional qualification. However, there was no research on clinic and subject at all due to the limitation of data collection. Thus, it could be known to have limitation to application of DEA analytical results to practical business. Also, the variables, which were used in the prior researches, are being used by being mixed the absolute value and the ratio value. Physical variable and financial variable are mixed. Thus, it was discovered a fact that may cause distortion of the analyzed results. In DEA analytical model, there is a problem of analyzing input variable and output variable at once without division of efficiency index and performance index. Thus, the methodological improvement could be known to be needed. Also, to reflect characteristics possessed by healthcare institution, a partial research was attempted that supplemented variable of quality in medical care. However, a specifically empirical research was failing to be progressed. Accordingly, this study suggests importance of efficiency evaluation in medical institution, and will come to present a reason that the detailed efficiency analysis is needed from clinic to unit, and the detailed developmental direction in the aspect of variable and analytical model for analyzing efficiency.

Objective: Although the therapeutic outcome of aggressive non-Hodgkin's lymphoma (NHL) has been considerably improved by the introduction of combination chemotherapy, many patients still fail to achieve complete response(CR) and/or long-term survival. Because the outcome appears to depend on certain prognostic factors, long term prognosis can be predicted by identification of risk group. And also, the patients in high risk group may benefit from new therapeutic modality. In 1993, the international prognostic index model for aggressive NHL as developed far the purpose of predicting outcome and designing of therapeutic trial. Thus, analysis of prognostic factors was performed to identify independent factors for the end points of CR, overall survival, and disease-free survival. Methods : From 1989 to 1994, total 340 patients were treated with combination chemotherapy and/or radiotherapy for NHL in Korea Cancer Center Hospital. Among 340, informations on eleven prognostic factors(sex, age, performance status, Ann Arbor stage, serum LDH level, tumor size, number of extranodal disease sites, bone marrow involvement, presence of B symptom, sex, time to CR, and histologic grade) were avaliable for 273 patients. Among these, 221 patients with aggressive NHL(NCI clinical schema) were eligible for the prognostic factor analysis for the response and survival. Also, 186 patients were eligible to determine whether International Prognostic Index Model could be applicable for Korean NHL. Results: One hundred fifty patients(68%, 95% CI 62-74%) achieved a complete remission, 43 patients (20%) a partial remission. With a median follow-up of 3,5 years, overall 3 year survival rate was 6396, and 3 year DFS for the 150 CRs was 72%. In a univariate analysis for the CR and survival, Ann Arbor stage, number of extranadal disease, performance status, presence of B symptoms, presence of BM involvement, serum LDH level and histologic grade were found to be statistically significant prognostic factors. Among them, by multivariate analysis, number of extranodal disease(RR 0.2, 95% CI 0.1-0.7), B Symptoms (RR 0.4, 95% CI 0.2-0.9), and histologic grade(RR 0.2, 95% CI 0.08-0.7) showed to be independent adverse prognostic factors for CR. For disease-free survival, Ann Arbor stage(RR 2.6, 95% CI 1.1-6.4) was independent risk factor. For overall survival, number of extranodal involvement(RR 2, 95% CI 1.3-4) and histologic grade(RR 2, 95% CI 1.2-3.7) were independently significant prognostic factors. With these 2 independent prognostic factors for survival, we could establish a prognastic index model which could separate the high risk patients. However, the usefulness of this model should be confirmed in a larger patient population. The dose intensity of cyclophosphamide, during initial 3 months of treatment, was significantly associated with CR rate and overall survival(p=0.01 & 0.03, respectively). When International Prognostic Index Model was applied to our patients, patients in the lower risk groups had significantly better outcome than patients in the higher risk groups(3 year survival and RR: 77% & 1 for low risk group, 61% & 1.9 for low-intermediate risk group, 50% & 2.2 for high-intermediate risk group, and 25% & 6 for high risk group). Conclusion: In this study, we confirmed that features other than the Ann Arbor stage were independently associated with CR and survival, and the International Prognostic Index Model would be an useful tool for the selection of high-risk patients who could be benefited from more aggressive chemotherapy.

Byeung-Cheol An,Young-Bog Ham,Mojiz Abbas Trimzi,Gi-Tae Lee,Jung-Ho Park,So-Nam Yun 유공압건설기계학회 2015 유공압건설기계학회 학술대회논문집 Vol.2015 No.10

Since the fluid pressure is applied to open-close process, the ball-type check valve is suitable in the high pressure condition. Especially, it is essential for ball-type check valve to design the response speed related with ball size, ball mass, flow rate from pump. Flow rate defines the closing time. And the closing time must to shorter than the stroke time for plunger. In this paper, we suppose the equation to calculate the response speed, and then we applied this equation to the check valve really being used. Based on this equation, the check valve will have been designed.

저체온 개심술시 혈당 및 전해질치의 변화에 관한 연구

유병렬,김흥대,이태숙 영남대학교 의과대학 1987 Yeungnam University Journal of Medicine Vol.4 No.1

1986년 6월부터 8월사이에 영남대학교 의과대학 부속병원에서 시행된 개심술 환자 25명(체중 5.1Kg~54.0Kg)에서 충전액내의 혈당치가 100mg % 이하인 2예에서만 포도당을 혼합하고 그 외에는 포도당을 혼합하지 않고 만든 인공심폐기의 충전액을 사용한 저체온하 체외순환시 혈당과 전해질치의 변화를 관찰하였던 바 다음과 같은 결과를 얻었다. 1) 체외순환전 충전액의 혈당치는 151.6±31.3mg% 였다. 2) 마취유도후의 채취혈에서 환자의 혈당치는 93.3±16.9 mg% 이었으며 부분체외순환이 시작되어 환자의 혈액과 충전액이 혼합된후의 혈당치는 135.9±26.9 mg%이었다. 3) 체외순환중 혈당치는 체온이 하강함에 따라 점차 증가되어 전체외순환 90분후에는 224.0 ±25.0mg%로 부분체외순환시 혈당치인 135.9±26.9mg%보다 현저하게 증가되었으며(P<0.005) 체외순환종료시에는 체온상승으로 인하여 점차 감소되어 체외순환종료 1시간후에는 151.8 ±31.6mg%로 체외순환 90분후 보다는 낮았으나 (P<0.005), 부분체외순환시 보다는 높았으며(P<0.05) 체외순환기간이 길수록 혈당치는 증가되었으나 나이와 질환에 따른 차이는 없었다. 4) 혈청k+ 치는 전체외순환 60분 후에는 2.9 ±4.0mEq/L로 부분체외순환시의 3.3 ±0.6mEq/L보다 낮게 유지되었으며 (P<0.005) 체외순환종료 후에는 점차 증가되었고 혈청 Ca++ 치는 체외순환중에는 높게 유지되었으나 체외순환 후에는 점차 감소되었다. 이상의 결과로 미루어보아 충전액에 다량의 포도당용액을 관례적으로 사용하는 것보다는 저장전혈의 혼합에 따른 충전액내의 포도당치를 계산한 후 필요에 따라 포도당액을 추가하는 것이 저체온체외순환중의 고혈당증을 예방할 수 있는 타당한 방법으로 생각되며 앞으로 충전액에 대한 더 많은 연구가 필요할 것으로 사료된다. This study deals with the changes in the concentrations of blood glucose and electrolytes during open heart surgery. Blood glucose and electrolytes in connection with age, disease and anesthetic period were measured in 25 patients about to undergo heart surgery which were performed between June 1986 and August 1986 in Yeungnam University Hospital. Because glucose solution is commonly used as priming solution, and the priming solution is hyperglycemic and hyperosmolar, glucose level of priming solution in this study was adjusted to 100-200mg% level to minimize hyperglycemic and hyperosmolar effect. The following results were obtained. 1. Glucose level of priming solution before extracorporeal circulation was 151.6 ±31.3mg%. 2. With body cooling, blood glucose level was elevated. As duration of extracorporeal circulation is prolonged, blood glucose level was elevated more, but no difference between age and diseases were observed. On warming, blood glucose level was progressively lowered. 3. Despite the low serum potassium level during by-pass, the potassium level was progressively elevated following by-pass, cut the serum potassium level was low compared to control values. Elevated calcium level was maintained during by-pass.
