1998년 9월 말경, 경남 지역의 양식 은어(Plecoglossus altivelis)에서 미포자충증이 발생하였다. 채집 당시, 하루 약 200마리씩의 폐사가 10일째 진행되고 있었으며 약 10%의 누적폐사율을 나타내었다. 병어는 입올림을 하거나 기면 상태에 있었으며, 대부분 체색흑화 및 복부팽만 소견을 보이고 있었다. 아가미, 아가미 뚜껑, 각종 내장, 복강벽 및 생식소에 직경 1~3㎜의 흰색 결절이 다수 형성되어 있었다. 감염 어종, 기생충의 형태 및 xenoma 분포 장기의 다양성에 근거하여 Glugea plecoglossi에 의한 감염증으로 추정되었다. 병리조직학적 검사를 실시한 결과, 광범위한 장기에 걸쳐 xenoma를 형성하고 있었으나 xenoma 인접조직에 변성 변화는 없었다. 아가미 새변, 비장, 두신 및 체신의 조혈영역에 심한 울혈 소견이 인정되었고, 간장, 심근 및 신세뇨관 국소에는 응고 내지 액화괴사 소견이 확인되었다. 따라서, xenoma의 인접조직에 대한 물리화학적인 영향보다는 xenoma형성 장기 및 조직에 야기된 국소 순환장애가 은어의 폐사와 직접적인 관련을 갖는 것으로 사료되었다. On September in 1998, a microsporidian infection was recognized in ayu, Plecoglossus altivelis, farmed on Kyongnam province of South Korea. Cumulative mortality was around 10% in 10 days. Infected fish which were piping for air near the surface of the water or in the asphyxic, lethargic condition revealed darkening of body and abdominal distention. Numerous whitish nodules up to 3㎜ in size were observed throughout most of body organs and tissues including gill, operculum, peritoneal wall and organs. Xenomas were also histologically confirmed in multiple internal organs with the evidences suggesting circulatory disturbance. Based on the morphology of spore and xenoma, and the distribution of xenomas in organs and tissues, this disease was diagnosed to be a microsporidiosis caused by Glugea plecoglossi. The mortality might be deeply related to the local circulatory disturbance by xemonas rather than the mechano-chemical effect of xenomas on adjacent tissues.

The objective of this study is keeping up radiation safty control from uranium material contamination. Accordingly, the check and radiation monitoring of the lagoon has been perfomed periodically. The liquid waste in lagoon will be vaporized mostly into the atomosphere by spontaneity of natural pheonmeunm after about four years.The uranium concentration in the liquid waste of lagoon reduced considerably to about 40 ppm from 2 g/l quantities of this early year due to uranium precipitation.

The characteristics of cement pastes and mortars containing zeolite A were investigated. The hydration of C₃S was a little restrained in cement pastes containing Zeolite A. The cement pastes containing zeolite A also exhibited that the formation of Ca(OH)₂ decreased and the amount of macropores increased with zeolite content. The strength of the mortar admixed zeolite A was lower than that of plain and decreased with zeolite content. These results would be related to the residual NaOH in the powder of zeolite A, which had influence on the cement hydration.

Background and Objectives Sialendoscopy is a minimally invasive technique that can be used to explore the salivary duct system and to treat obstructive salivary disease. The aim of this study was to investigate the safety and efficacy of sialendoscopy as a diagnostic and therapeutic tool for recurrent parotid swelling. Subjects and Method We retrospectively evaluated the endoscopic findings of 41 patients who underwent diagnostic sialendoscopy between August 2003 and January 2008. Interventional sialendoscopy was performed to treat any abnormalities in the ductal system. Stones were fragmented or removed by using a basket or a grasper. Strictures were dilated and mucous plugs were removed endoscopically. Results Diagnostic sialendoscopy was successfully performed in all cases. Thirty four patients underwent interventional sialendoscopy. Among them, 8 patients (23.5%) had intraductal stones and 7 patients (87.5%) were successfully treated by endoscopic removal. Stenosis of parotid duct was observed in 26 patients (76.5%). Sixteen cases (61.5%) with stenosis were dilated with balloon catheter or endoscopy sheath successfully. Patients were closely observed during the median follow-up of 42 months (1-72 months). Symptomatic relief was achieved in 20 of 26 patients (77%) in parotid stenosis. There were no recurrences of parotid stone. Six patients (23.0%) among 26 patients with parotid ductal stenosis occasionally suffered from recurred parotid swelling. Conclusion The sialendoscopy could be recommended as a useful tool for the diagnosis and treatment of recurrent parotid swelling with a minimally invasive technique.

This work has been carried out to study the mixing characteristics of solid in vibrating feeder by dispersion model.The experimental variables were particle size, particle densities, vibration amplitude and vibration frequency etc.The system consisted of two particles such that fine particles were located on the top of the coarse particles before vibratory mixing had started.It was found from this study that dispersion model can effectively explain the mixing characteristics of solid in vibrating feeder.
