This study was conducted to find an odor reducible solution in Hwayang agricultural industrial complex. Civilcomplaints have lasted because of odor caused by recycled plastic producers. In order to understand the emissioncharacteristic and concentration of key odor components, we investigated the complex odor and 17 odorcompounds at 3 sites of five chemical facilities from march to october 2013. The results of complex odor showed8~12 at a boundary of 5 facilities. The results of complex odor showed 6694, 3000, 1442 at an emission (stack)of 3 facilities, which exceeded the emission standard. The highest compound and its concentration of each sitewas different because each facility has different processes and use different raw materials. We suggested thesuitable prevention facility for each company to reduce odor. We analyzed the odor contribution with the emission(stack) point of S, I, B and the inside point of W, J. S plant was Acetaldehyde (45%), I plant was Trimethylamine(32%), B plant was Styrene (35%), W plant was Hydrogen sulfide (42%), J plant was Hydrogen sulfide(41%). An objective of study is odor management area and will apply odor strict emission standards. A suitable preventionfacility should be operated efficiently based on survey data to reduce odor.

This study was conducted to evaluate the emission characteristics of air pollutants from incineration facilities inJeollanam-do. We selected 8 incineration facilities depend on type and the 19 items such as dust etc. were measured atthe measurement hole for emission gas from air contamination control units. The range of emission concentrations fordust was 2.8 ~ 20.9 mg/Sm3 less than permissible air discharge standards. The results of 10 gaseous contaminants suchas SOx was less than permissible air discharge standards. The range of emission concentrations for NOx was13.4 ~ 120.0 ppm, less than permissible air discharge standards. As G facility was 112.4 ppm, 120.0 ppm, it exceededemission standard (100 ppm) twice. The range of emission concentrations for HCl was ND ~ 85.300 ppm, B Facilitiyexceeded emission standard (20 ppm) as 85.300 ppm. The range of emission concentrations for NH3 was ND ~ 76.333ppm, A, D, H Facility exceeded emission standard (30 ppm). The concentration of each facility was 42.416 ppm, 62.930ppm, 76.333 ppm. The results of heavy metals (5 items) showed within emission standards. G facility is operating incondition that input of urea is 100 L/day. If input of urea were changed to 50 ~ 75 L/day, the operating cost of air pollutionprevention facility can be reduced by 25% ~ 50%. In this study, the correlation between urea input and nitrogen oxideswas statistically significant, but the correlation between urea input and ammonia showed insignificantly. Our researchattempts to evaluate the emission characteristics of air pollutants from incineration facilities and to institute a reductionplan, an effective management of incinerators.

Pulmonary embolism (PE) is defined by acute PE with sustained systemic arterial hypotension. Risk of dying of PE is estimated about 30% if an inotropic support is required and no cardiopulmonary arrest occurs. Rivaroxaban is an oral factor Xa inhibitor and the effect before or after administration of fibrinolytics in massive PE is still unknown. We report 2 patients with massive PE on rivaroxaban. One was successful in rivaroxaban after thrombolytic therapy, and the other one was failure to reverse right heart failure until thrombolytic therapy was administered. We report two cases with massive PE in whom successfully reverse RV failure with fibrinolytic therapy. In view of administration of rivaroxaban in patients with massive PE, one showed similar efficacy of rivaroxaban with currently used anticoagulants after administration of fibrinolytic agent, and the other one showed limited efficacy of rivaroxaban without antecedent administration of fibrinolytic agent.

서론: 현재 아광범위 폐색전증에서 혈전용해치료의 생존이득에 대해서는 논란이 있다. 본 연구는 혈전용해 치료 유무에 따른 광범위 및 아광범위 폐색전증 환자들의 단기 사망률에 대해 알아보고자 하였다. 대상 및 방법: 2004년 1월 1일 부터 2011년 7월 30일 까지 91개월 동안 순천향대학교 서울 병원에서 정맥혈전증을 진단 받은 환자 중 광범위 및 아광범위 폐색전증 환자를 대상으로 하여 후향적 챠트분석을 하였다. 일차 결과는 치료 30일 이내의 사망으로 하였으며 이차 결과는 30일 이내의 주요 출혈, 90일 이내의 사망, 90일 이내의 정맥혈전증의 재발로 하였다. 결과: 연구기간 동안 광범위 폐색전증은 13명으로 연령 중간값은 79세(25-90세), 아광범위 폐색전증은 26명으로 연령 중간값은 70세(37-96세)였다. 혈전용해치료를 받았던 환자에서 30일 이내 사망은 5명(광범위 4/9명, 아광범위 1/12명)이었고 혈전용해치료를 받지 않았던 환자에서 30일 이내 사망은 4명(광범위 1/4명, 아광범위 3/14명)이었다. 혈전용해제 투여 후 30일 사망률과 90일 사망률은 동일하였다. 혈전용해제 투여를 시행한 군과 시행하지 않은 군에서 군간 생존율의 차이는 없었다. 생존에 대한 다변량 분석을 하였을 때 광범위 폐색전증의 유무가 유의한 독립적인 예후인자였다(HR: 4.016). 추정 사망 원인은 혈전용해제 치료군에서 5명 중 4명에서 우심실 부전으로 인한 순환기 허탈이었고 1명은 치명적 출혈로 인한 사망이었다. 혈전용해제 투여를 시행하지 않은 군에서 4명 모두 우심실 부전으로 인한 순환기 허탈이 사망 원인으로 추정되었고 치명적 출혈은 없었다. 주요출혈은 총 39명 중 2명에서 발생하였다. 90일 이내 정맥혈전증의 재발은 없었다. 결론: 광범위 및 아광범위 폐색전증 환자들의 단기 사망률은 혈전용해 치료 유무에 따른 차이가 없었다.
