  • The annual total phosphorus load caused by public wastewater, nightsoil and livestock manure treatment facilities in Korea has been examined macroscopically. Annual domestic average phosphorus (P) inflows through the income of phosphate rock for the last five years (2012 - 2016) were analyzed as 76,598 tons/year. As of the year 2015, the total loadings of phosphorus attributed to public wastewater treatment facilities, nightsoil treatment facilities and livestock wastewater were estimated as 30,269 tons/year, 1,909 tons/year and 18,138 tons/year, respectively. Considering the amount of phosphorus imports, the annual phosphorus load from wastewater, livestock wastewater and excretions is equivalent to 39.5%, 23.7%, 2.5% and totally 65.7%(39.5% + 23.7% + 2.5%). Therefore, the introduction of phosphorus recovery and recycling processes for the public wastewater and livestock manure treatment facilities has been found to be effective because it could reduce the import amount of phosphate rock by up to 60% or more.

  • 96 patients underwent cardiac valve replacement for valvular heart diseases consecutively between February 1986 to February 1990 in the Department of Thoracic and Cardiovascular Surgery of Yeungnam University Hospital. The follow up period was between 6 months and 4.5 years postoperatively[mean 23.4$\pm$13.1 months]. 75 cases got mitral valve replacement, 6 cases, aortic valve replacement, 15 cases, double valve replacement. 30[31.2%] patients were male and 66[68.8%] were female and the age ranged from 14 to 66 years old. Early hospital death within 30 days postoperation were 5 patients[5.2%], consisting of by low cardiac output in 2, infective endocarditis in 1, multiple organ failure with sepsis in 1 patient. There was no late postoperative death. Most common early postoperative complication was wound disruption [8.7%] and then low cardiac output, pneumothorax, pleural effusion in order. Most common late postoperative complications were minor bleeding episodes[8.7%] related to anticoagulant therapy which were consisted of frequent epistaxis in 3, gum bleeding in 2, hemorrhagic gastritis in 1, hypermenorrhea in 1, hematoma in right arm in 1 patient. Valve-related complications included valve thrombosis [1.6%/ patient-year], valve failure due to pannus formation[1.1% /patient-year], prosthetic valve endocarditis[1, 1%o/patient-year] and minor anticoagulant hemorrhage[4.4% /patient-year]. 5 cases of reoperations were performed in 4 patients due to valve failure and all of them were in the mitral positions[2.7% /patient-year]. Cardiothoracic ratios in the chest X-ray decreased at the 6th month and 1st year postoperation in all patients. But in New York Heart Association[NYHA] functional class IV, no change in cardiothoracic ratio was found between 6 months and 1 year postoperation. In the echocardiogram, the size of the cardiac chambers decreased, but ejection fraction increased postoperatively in each functional class. In the electrocardiogram, decreases were found in the incidence of atrial fibrillation, left atrial enlargement, left ventricular hypertrophy with right bundle branch block increasing postoperatively in each functional class. The actuarial survival rate was 98.4% for all patients, 98.7% for mitral valve replacement, 83.8% for aortic valve replacement, and 80% for double valve replacement at the end of a 4.5 year follow up period. Meanwhile the actuarial freedom rate was 91.5% for prosthetic valve endocarditis, 91.6% for thromboembolism, 89.0% for prosthetic valve failure and 83.7% for minor anticoagulant hemorrhage. Preoperative NYHA class III and IV were 75% of all patients, but 95% of all patients were up graded to NYHA class I and II postoperatively.

  • Clinical results with the xenograft cardiac valves were reviewed for 212 patients who underwent heart valve replacement from January 1981 to December 1987. One hundred and twenty-four Carpentier-Edwards k 88 Ionescu Shiley valves were used. Overall operative mortality was 11 out of 212[5.1%]: 5 out of 153[3.39o] for mitral valve replacement [MVR], 2 out of 34[5.9%] for aortic valve replacement [AVR], 0 out of 4[0%] for Tricuspid valve replacement [TVR], and 4 out of 21[19.1%] for double valve replacement [DVR;MVR+ AVR]. Two hundred and one operative survivors were followed up for a total of 824.3 patient-years [a mean 3.9*1.8 yrs], and the follow up was 78.1%. The linealized complication rates were 0.1% emboli / patient-year, 1.0% endocarditis/ patient-year and 2.2% overall valve failure / patient-year. A linealized rate of primary tissue failure was 0.7*/o/ patient-year. The actuarial survival rates including the operative mortality were 92*2.8% at 4 years and 85*4.3% at 7 years after surgery using the Xenograft cardiac valves. Probabilities of freedom from thromboembolism and overall valve failure were 73*11.0% and 69*2.4% at 7 years after surgery using the Xenograft cardiac valves respectively. The intrinsic durability of the Xenograft cardiac valves appears to be relatively well satisfactory over the long term [4 to 7 years] and the risk of failure appears well balanced by the advantages of a low incidence of thromboembolism and no mandatory anticoagulant therapy.
