Regression models were obtained on the base of the correlation between Phytophthora blight incidence in red pepper and the microclimate data obtained from automated weather station (AWS) during 1997 and 1998. A computer program (PEPBLIGHT) was constructed based on the model that the R2 value is highest among regression models. This computer program uses the microclimate data from more than one AWS through the common dialogue box easy and it is able provide disease forecasting information. In addition, it could be applied for other diseases and converts the microclimate data of AWS to the input data for Statical Analysis System (SAS). PEPBLIGHT was first developed for the forecasting computer system of red pepper blight in Korea. PEPBLIGHT is operated on the MS Windows, so that it is easy to use.

Purpose: To evaluate the effectiveness of emergent transcatheter arterial embolization(TAE) in the treatmentof bleeding from ruptured hepatocellular carcinoma(HCC) and long-term follow-up. Materials and Methods: Twentypatients with ruptured HCC underwent emergent TAE; diagnosis was based on clinical and radiologic findings.Mesoportography was used to determine the presence of portal vein thrombosis, and celiac angiography to determinethe presence of hypervascular mass and extravasation of contrast material. All patients underwent TAE; a mixtureof adriamycin, mitomycin, lipiodol, and gelfoam particles was used. In four of the 20 patients, adjuvantembolization was performed, using stainless steel coils. After three week of follow-up CT, follow-up TAE wasperformed between two and ten times. Results: Technical and clinical success was up to 100%. Mesoportographyshowed the presence of portal vein thrombosis in nine patients and its absence in 11. In 15 patients, three weeksof follow-up by CT showed lipiodol uptake by the mass and the disappearance of highly attenuated peritoneal fluid.Within one week of embolization, four of the 20 patients died of sepsis, shock, and hepatic failure, and withinone month of this procedure, one died of renal failure. Three-month, six-month, and one-year survival rates afterTAE were repectively 50%, 45%, and 30%; the mean duration of survival was 260 days. In nine patients with portalvein thrombosis, the one-year survival rate was 11%, while in 11 patients not suffering from this condition, therate was 70%; the difference between the two groups was statistically significant(p < 0.05). Conclusion: As thefirst choice of treatment for patients with hemoperitoneum from ruptured HCC, emergent TAE is an effective,life-saving therapeutic procedure; in these patients, portal vein thrombosis may be a factor influencing risk andprognosis.

Due to the complexity and large size of buildings, plastic resin is widely used as a building material. Accordingly, theoccurrence of fires caused by plastics is increasing. Due to the nature of plastic resin fires, the amount of damage toproperties and human life caused by combustion products such as smoke are large, and these damages are related to smokeproduction and smoke generation. Therefore, this study reviews smoke measurement methods and laws on domesticbuildings and fire services. Experiments were conducted based on three smoke-related test standards (ISO 5660-1, ISO12136, ASTM E 662). The experiment results indicate a total smoke production and generation by PP, PVC, and PMMAof 43.27, 32.83, and 12.33 m2, and 27.855, 9.599, and 6.975 g, respectively. 건축물의 복잡화, 대형화로 인해 합성수지를 건축 재료로써 많이 활용되고 있다. 이에 따라 합성수지가 원인이되는 화재의 발생이 증가하고 있다. 합성수지 화재의 특성으로는 연기 등 연소생성물로 인한 인명 및 재산피해가크다는 점이고, 이는 연기생성과 발생과 관계된다. 이에 본 연구는 국내 건축 및 소방관계법령과 연기측정방법에 대해 검토하고, 연기관련 3가지 시험기준(ISO 5660-1, ISO 12136, ASTM E 662)을 바탕으로 실험을 실시하였다. 실험에대한 결과로 연기생성 관련 데이터에서는 PP 43.27 m2, PVC 32.83 m2, PMMA 12.33 m2 순으로 나타났고, 연기발생관련 데이터에서는 PVC 27.855 g, PP 9.599 g, PMMA 6.975 g 순으로 나타났다.
