Very few molecular studies on the phylogeny of the karyorelictean ciliates have been car- ried out because data of this highly ambiguous group are extremely scarce. In the present study, we sequenced the small subunit ribosomal RNA genes of three morphospecies rep- resenting two karyorelictean genera, Kentrophoros, Trachelolophos, and one haptorid, Trache- lotractus, isolated from the South and East China Seas. The phylogenetic trees constructed using Bayesian inference, maximum likelihood, maximum parsimony and neighbor-joining methods yielded essentially similar topologies. The class Karyorelictea is depicted as a monophyletic clade, closely related to the class Heterotrichea. The generic concept of the family Trachelocercidae is confirmed by the clustering of Trachelolophos and Tracheloraphis with high bootstrap support; nevertheless, the order Loxodida is paraphyletic. The transfer of the morphotype Trachelocerca entzi Kahl, 1927 to the class Litostomatea and into the new haptorid genus Trachelotractus, as suggested by previous researchers based on morpho- logical studies, is consistently supported by our molecular analyses. In addition, the poorly known species Parduczia orbis occupies a well-supported position basal to the Geleia clade, justifying the separation of these genera from one another. -

WM2013 Conference, February 24 – 28, 2013, Phoenix, Arizona, USA Radon Concentration in Groundwater in the Central Region of Gyeongju, Korea - 13130 Jung Min Lee 1, A Rim Lee 1, Chan Hee Park 1, and Joo Hyun Moon 1* 1 Dongguk University, Seokjangdong, Gyeongju, Gyeongbuk, 780-714, Republic of Korea ABSTRACT Radon is a naturally occurring radioactive gas that is a well known cause of lung cancer through inhalation. Nevertheless, stomach cancer can also occur if radon-containing water is ingested. This study measured the radon concentration in groundwater for drinking or other domestic uses in the central region of Gyeongju, Korea. The groundwater samples were taken from 11 points chosen from the 11 administrative districts in the central region of Gyeongju by selecting a point per district considering the demographic distribution including the number of tourists who visit the ancient ruins and archaeological sites. The mean radon concentrations in the groundwater samples ranged from 14.38 to 9050.73 Bq·m-3, which were below the recommendations by the U.S. EPA and WHO. Key words: Radon, naturally occurring radioactive gas, groundwater, Gyeongju INTRODUCTION Radon gas is a naturally occurring radioactive gas that is formed in the decay series of uranium and thorium. Since both these series are ubiquitous, radon gas is produced continually in all soils depending on the concentration of uranium or thorium. [1, 2] A portion of the radon released by radioactive decay moves through the air or water-filled pores in the soil to the soil surface and enters the air, whereas some remains below the surface and dissolves in the groundwater. -
A Redescription of Remanella Multinucleata (Kahl, 1933) Nov
Europ. .J. Protistol. 32,234-250 (1.996) European Journal of Mav 31, 1996 PROTISTOLOGY A Redescription of Remanella multinucleata (Kahl, 1933) nov. gen., nov. comb. (Ciliophora, Karyorelictea), Emphasizing the lnfraciliature and Extrusomes Wilhelm Foissner Universität Salzburg, lnstitut für Zoologie, Salzburg, Austria SUMMARY The morphology, infraciliature, and extrusomes of Remanella mwbinwcleata (Kahl, 1933) nov. comb. were studied in live cells, in protargol impregnated specimens, and with the scanning electron microscope. The entire somatic and oral infraciliature consists of diki- netids which have both basal bodies ciliated or only the anterior or posterior ones, de- pending on the region of the cell. The right side is densely ciliated. Its most remarkable specialization is a kinety which extends on the dorsolateral margin from mid-body to the tail, where the kinetids become condensed and associated with conspic- uous fibres originating from the ciliated anterior basal bodies. The left side seemingly has two ciliary rows extending along the cell margins. Flowever, detailed analysis showed that these rows arevery likely a single kinety curving around the cell. The oral infraciliature of Remanella isverysimilartothat of Loxodes spp.,i.e.consistsof fourhighlyspecialized and specifically arranged kineties, whose structure is described in detail. Previous inves- tigations could not determine whether or how the nematocyst-like extrusomes of Rema- nella are extruded. The present study shows that they are discharged, thereby assuming a unique, drumstick-like shape because the roundish extrusome capsule remains attached to the despiralized filament. The data emphasize the close relationship between Remanella and Loxodes, earlier proposed by Kahl, and suggest that they emerged from a common ancestor which looked similar to a present day L oxodes. -

The Infraciliature of Cryptopharynx Setigerus KAHL, 1928 and Apocryptopharynx Hippocampoides Nov
Arch.

(Ciliophora, Karyorelictea), with an Account on Evolution in Loxodid Ciliates WILHELM FOISSNER Universitat Salzburg, Institut fOr Zoologie, Salzburg, Austria Summary: The morphology and infraciliature of Cryptopharynx setigerus KAHL, 1928, Cryp topharynx spp., and Apocryptopharynx hippocampoides nov. gen., nov. spec. were studied in live and protargol impregnated specimens. The entire somatic and oral infraciliature consists of dikinetids which have both or only the anterior basal bodies ciliated, depending on the region of the cell. The right side is densely ciliated. Its most remarkable specialization is a kinety which extends on the dorsolateral margin from mid-body along the broadly rounded posterior end to the postoral ventral surface. The left side bears a single ciliary row which extends along the cell margins, i.e. is almost circular. The oral infraciliatures of Cryptopharynx and Apocryptopharynx are, like the somatic infraciliatures, very similar to those of Loxodes and Remanella, i.e. consist of two specialized buccal kineties which extend along the right, anterior, and left margin of the buccal overture. These kineties form a paroral ciliature and very likely evolved from somatic cil iary rows, providing support for SMALL'S hypothesis that the oral ciliature of the ciliates is of somatic origin. An intrabuccal kinety extends within the buccal cavity; possibly, it is part of the left lateral ciliature and would then be an adoral. The intrabuccal kinety is slightly curved in Cryptopharynx and clip-shaped elongated in Apocryptopharynx hippocampoides and C. -

We applied the frequency ratio (FR), decision tree (DT), and random forest (RF) methods to seismic data for Gyeongju, South Korea. A magnitude 5.8 earthquake occurred in Gyeongju on 12 September 2016. Buildings damaged during the earthquake were used as dependent variables, and 18 sub-indicators related to seismic vulnerability were used as independent variables. Seismic data were used to construct a model for each method, and the models’ results and prediction accuracies were validated using receiver operating characteristic (ROC) curves. The success rates of the FR, DT, and RF models were 0.661, 0.899, and 1.000, and their prediction rates were 0.655, 0.851, and 0.949, respectively. -

Radionuclides deposited in soil are transported by precipitation to nearby environments and contaminate the surface water system. Basic data on surface watershed and soil erosion models have been collected and analyzed to evaluate the behavior of radionuclides deposited on surface soil after a nuclear acci- dent. Data acquisition and analysis in aquatic environment were performed to investigate the physical characteristics and variation of biota in rivers and lakes of the Nakdong river area near the Wolsong nuclear power plant. For these purposes, a digital map, and hydrological, water quality and biota data were gathered and a systematic database (DB) was constructed in connection with them. Constructed aquatic DB will be supplied and used in surface watershed and soil erosion models for investigation of long-term movement of radionuclides in adsorptive form in surface soil. Finally, basic data and established models will be utilized for general radiological impact assessment in aquatic environment.
