Twenty patients with symtomatic congenital cysts in the liver. kidney. thyroid. and lower n eck underwe nt. ultrasound guided percutaneous aspiration through a dra inage catheter with te mporary instillation of 95% ethanol into the cyst . Our procedure was based on the method as described by Bean and Rodan(16l in 1985. Additionaly. two othe steps were odded to prevent the dilutional effect of residual cyst fluid . One was the preliminary washing of th e cyst with alcohol. The other was to treat with 30% replace m e nt of alcohol every 10 minutes during the treatm ent secession. Minor complications of transie nt temperature e levation and haziness occurred . butj no major complications were encountered.After the alcohol treatmen t follow up examinations were performed with computed tomography or ultrasonography a t 6 wee ks. 6 months. 9 months a nd 15 months. Although there was diminished size. recurrence was noted in 6 of twenty patients(30%l at 6 weeks and one of twenty patients(5%l at 6 months. There was no recurrence at 9 months a nd 15 months.The results indicated that perc utaneous aspiration a nd alcohol sclerotherapy are safe and effective the rapy for symptomatic congenital cysts.
This study investigates three buildings arranged alongside at the same level, namely, the Josadang, the Buljojeon, and the Palsangjeon. Their backside is blocked by an embankment with an environmental condition unsuitable for wooden buildings. The pillar behind the Josadang had termite damage for which termite damage and environmental investigations had been conducted for the past four years. The termite damage was monitored four times using the termite detection dogs, and the environmental factors were surveyed 27 times, except during the winter season. As a result, the locations of the columns with a high frequency of responses from the termite detection dogs were found and damage was confirmed. According to the surface moisture content investigations, the surface moisture content was highest in the Josadang and lowest in the Buljojeon. After a statistical analysis, the mean, the median, and the mode values were compared. The difference between the mean and the median was found to be less, however, the mode varied significantly. The mode values of the Josadang and the Palsangjeon were 14.5% and 10.8%, respectively, higher than the 6.1% mode value of the Buljojeon. It was concluded that the temperature and the water content affected the termite damage, which increases if the temperature and the water content remain constant owing to the environmental factors.
This study was conducted to investigate lichen as a typical biomass damage on the surfaces of flagpolesupporting stones in the Beopjusa temple. The lichens present on the flagpole-supporting stones were limited to five species. Two dominant lichen species were identified: Aspicilia sp. and Pertusaria flavicans. One foliose species and one fruticose species, which are rarely observed on crustose lichens, were identified as Xanthoparmelia conspersa and Ramalina sekika, respectively. The lichen inhabiting the black algae layer was confirmed as Leprocaulon textum. ATR-FTIR was performed to analyze the secondary metabolites synthesized by the lichens. By comparing the FTIR spectra of Xanthoparmelia conspersa and Ramalina sekika, the synthesized organic acids were confirmed to differ from each other. Furthermore, the spectral changes and characteristics due to functional groups in the molecules were confirmed.
Biological damages of wooden cultural properties are closely related to the preservation of the environment; these damages can be accelerated because of rapid climate change. Therefore, to preserve cultural properties, it is important to understand environmental characteristics. This study aims to investigate the status of termite damage and the characteristics of major environmental factors such as micro-meteorology, meso-meteorology, and local-meteorology of the Josadang shrine in the Seonamsa temple at Suncheon. Damage was confirmed by visual observation and the response of the termite detection dog at the northwest corner. Also another damage was observed by the termite detection dog at the northeast corner. These pillars had lower surface temperature and higher moisture content compared with the pillars in the front. The mean temperature of the entire time was similar for the meteorologies; however, the relative humidity differed. High relative humidity, greater than 70%, was observed frequently. In particular, it was determined that the termite activity days were the most inside the Josadang shrine. The statistical analysis confirmed that there was a difference between the meteorology events through the F ratio. In addition, the difference of environmental factors with relative humidity and temperature was identified more great difference in relative humidity through the t-statistics of temperature and relative humidity. And then relative humidity was confirmed most great in the difference of meso-meteorology and local-meteorology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
