Effect of reclaimed sewage on the paddy rice culture was examined by field experiment for two consecutive years. The domestic sewage was treated by the constructed wetland, and the effluent of the treatment wetland was used for irrigation water. Growth components and yields were compared against the CONTROL plot where conventional fertilization was applied. In general, addition of the reclaimed sewage irrigation which contained high nutrient concentration didn’t affect paddy rice culture adversely, and even better growth and more yields were observed. Overall, reclaimed sewage irrigation was thought to be one of practical alternatives for irrigation water.

목적: 급성 ST 분절 상승 심근경색증 환자에서 최초 의료접촉 방식 및 이에 따른 특성과 시간과의 관계를 조사했다. 방법: 전북 권역심혈관센터 데이터베이스에 등록된 527명의 일차적 관상동맥 중재시술을 받았던 급성 ST 분절 상승심근경색증 환자를 대상으로 의료 접촉 방식에 따른 일반적특징, 사회적 요인 및 시간 지연에 대한 예측 인자에 대해 조사했다. 결과: 전체 환자 중에서 28.8%만이 119를 이용했으며, 이들은 심부전, 심인성 쇼크 등의 임상 양상이 더 좋지 않았다. 최초 119를 이용하였어도 36.2%의 환자가 중재시술이 불가능한 병원으로 이송되었고 이들은 유의하게 증상 발생 후 관상동맥 중재술 시행까지 시간이 지연되었다(211.3 ± 358.0분vs. 320.2 ± 374.6분, p = 0.034). 증상 발생 후 관상동맥 중재술 시행까지 시간 단축의 독립적인 요인으로는 119를 이용(OR = 0.4, p < 0.001)하는 것과 이전 관상동맥 중재술 기왕력(OR = 0.4, p = 0.033)이었으며, 시간 지연의 독립적인 요인으로는 65세 이상의 고령(OR = 1.9, p = 0.003)과 중재술이 불가능한 병원을 먼저 내원한 경우(OR = 2.0, p < 0.001)였다. 결론: 전북 권역 심근경색증 환자들은 낮은 119 이용률을 보이며, 상당수가 중재시술이 불가능한 병원으로 이송되고 있다. 심근경색증에 대한 증상 인지율을 높이고 증상이 시작되면 즉시 119 구급차를 이용하여 중재시술이 가능한 병원으로 방문하도록 하는 홍보 및 교육이 필요할 것으로 생각된다. Background/Aims: The use of emergency medical services (EMSs) at the onset of pain, and the relationship between transport type and the treatment delay for acute ST-segment elevation myocardial infarction (STEMI) were evaluated using the Jeonbuk Regional Cardiovascular Center database. Methods: In total, 527 STEMI patients who underwent primary percutaneous coronary intervention (PCI) were enrolled in this study. Basic characteristics, socioeconomic variables, and delay factors were compared between patients that contacted an EMS as first medical contact (FMC) and patients that used other forms of FMC. Results: Only 28.8% of patients used EMS as their FMC. The patients that used EMS showed significantly shorter onset-to-balloon time than those who did not (250.7 ± 366.6 min vs. 405.9 ± 649.8 min, p = 0.001). However, 36.2% of patients that used EMS as FMC were transported to non-PCI-capable centers, which led to significantly prolonged onset-to-balloon time. Multivariate analysis revealed that transfer via another hospital (odds ratio [OR] 2.0, p < 0.001), EMS as FMC (OR 0.4, p < 0.001), age > 65 years (OR 1.9, p = 0.003), and previous history of PCI (OR 0.4, p = 0.033) were independent predictors of pre-hospital delay. Conclusions: EMS used as FMC at the onset of chest pain was an important factor for decreasing treatment delay in patients with STEMI. However, a small number of patients used EMS as FMC, and some patients that used EMS were transported to non-PCI-capable centers. Public campaigns and education are needed to raise the public awareness of STEMI and the use of EMSs. (Korean J Med 2016;90:507-513)

담수호에 유입되는 하천수에서의 SS와 COD 및 T-P와의 상관관계

When it rains, soil erosion occurs and soil particles move into the reservoirs or stream. Nutrients and contaminants, which are adsorbed on soil particles, flow into waterbody and are leached into water. Then they effect on water quality and eutrophication of reservoirs. In this study, correlation of SS to COD was surveyed, and that of SS to T-P was also done. R² values in wet period were almost over 0.8, but were very low in dry period. This shows that concentrations of COD and T-P will be assumed by using SS concentrations in wet period in stream.

Most esophageal lipomas are discovered incidentally and are small and asymptomatic. However, large (>4 cm) lipomas may cause various symptoms, including dysphagia, regurgitation, or epigastric discomfort. We present a 45-year-old woman with intermittent sudden choking and globus pharyngeus. Upper gastrointestinal endoscopy and endoscopic ultrasound revealed an approximately 10.0×1.5 cm pedunculated subepithelial tumor in the upper esophagus, identified as the cause of her symptoms. A thoracic computed tomography scan revealed a fat attenuated longitudinal mass along the upper esophagus, suggestive of a lipoma. Endoscopic resection of the lesion was performed with a detachable snare to relieve her symptoms, and the pathologic findings were consistent with a lipoma. (Korean J Gastroenterol 2016;68:210-213)

This study was performed to examine the rice growth and nutrient change in paddy soil with reclaimed sewage irrigation. Total nitrogen and total phosphorus in the experimental system were analyzed before and after rice culture. The experiment lasted three consecutive years, and this paper presents results of the last year. Additional supply of nutrients to the rice culture by reclaimed sewage irrigation was significant and it increased the yield. Nutrient uptake by rice plant increased with more nutrient supplied, however. there was limit in plant uptake. Nutrient accumulation occurred in the soil and it was more apparent for the phosphorus where most of the remaining quantity was accumulated while substantial amount of nitrogen was lost during the growing season. This study suggested that additional nutrient supply by reclaimed sewage irrigation might be a supplemental benefit to the rice culture, and it can help the fertilization management. However, long term effects of continual reclaimed sewage irrigation should be assessed carefully including nutrient mass balance in the paddy rice culture system.

Effect of reclaimed sewage on the paddy rice culture was examined by field experiment for two consecutive years. The domestic sewage was treated by the constructed wetland, and the effluent of the treatment wetland was used for irrigation water. The reclaimed sewage was diluted before irrigation in the first year, and it was used without dilution in the second year experiment. Growth components and yields were compared against the control plot where conventional method was applied. And also, soil characteristics of the plots before and after reclaimed sewage irrigation were analyzed. Generally, addition of the reclaimed sewage irrigation didn't affect paddy rice culture adversely and even enhancement was observed. Fertilization was thought to be important factor for rice culture rather than irrigation water quality. Conventional fertilization and reclaimed sewage irrigation which contained high nutrient concentration resulted in better growth and more yield. Unlike widespread concern lodging did not happen even in the case of irrigation with average 90mg/L of T-N and conventional fertilization. Soil characteristics changed after irrigation and significant EC increasing was observed for the reclaimed sewage irrigation plots. From soil analyses, salt accumulation could be a more potential problem than nutrients like nitrogen and phosphorus in the use of reclaimed sewage irrigation. Overall, reclaimed sewage irrigation was thought to be one of practical alternatives for the ultimate disposal of sewage in rural area.
