Grain size, the content of ignition loss (IL), and the concentrations of chemical oxygen demand (COD), acid volatile sulfide (AVS), and trace metals (Fe, Mn, Cu, Pb, Zn, Cd, Cr, As, and Hg) in surface sediments from the Taehwa River estuary, Ulsan, were measured to evaluate pollution levels and potential ecological risks of organic matter and trace metals in estuarine sediment. The mean grain size (Mz) of sediments in the study region ranged from $-0.8-7.7{\varphi}$ (mean $2.8{\pm}2.4{\varphi}$). Surface sediments in the upstream region of the Taehwa River were mainly composed of coarse sediments compared to the downstream region. The concentrations of IL, COD, AVS and trace metals in the sediment were much higher at downstream sites of Myeongchon Bridge in the vicinity of industrial complexes than at upstream sites of those in the vicinity of the residential areas due to the anthropogenic input of organic matter and trace metals by industrial activities. On the basis of several geochemical assessment techniques [sediment quality guidelines (SQGs), enrichment factor (EF), geoaccumulation index ($I_{geo}$), pollution load index (PLI) and ecological risk index (ERI)], the surfaces sediments in the study region are not highly polluted for trace metals, except for As. However, the higher concentrations in downstream study regions of the Taehwa River could impact benthic organisms including shellfish (i.e. Manila clam) in sediments.

To understand the geochemical characteristics of Gomso Bay, which features extensive Manila clam, we measured various geochemical parameters, organic matter, and trace metals (Cu, Cd, Pb, Zn, Cr, Hg, As and Fe) of intertidal and subtidal surface sediments in 2011. The surface sediments consisted of sedimentary facies including gravel (0.21%), sand (61.1%), silt (32.1%), and clay (6.5%). The chemical oxygen demand (COD) and acid volatile sulfide (AVS) values in most areas were below sediment quality criteria (COD, $20mg/g{\cdot}dry$; AVS, $0.2mg/g{\cdot}dry$). Trace metals in the surface sediments were below pollution thresholds, except for As (morderately polluted). Sediment quality was evaluated using the trace metal pollution load index (PLI) and ecological risk index (ERI), which showed that sediments were generally not polluted and at low risk; however, values along the outer bay were higher. We expect these results will be valuable for sustainable aquaculture prodution and environmental management in Gomso Bay.

Beryllium (Be), cobalt (Co), thallium (Tl) and vanadium (V) are candidates of 21 priority soil pollutants in Korea. The distribution of their concentration in soils from three contamination sources including industrial, roadside and mining areas was investigated. Concentrations of the metals were evaluated quantitatively using pollution indices and the fractionation of metals was conducted using modified SM&T (Standards Measurements and Testing programme) sequential extraction. Concentrations of the metals for all samples from industrial and roadside soils were within the range of natural background levels, while some of Be in soils from abandoned mines exceeded that the range. Enrichment Factor (EF) and Nemerow Integrated Pollution Index (NIPI) for Be, Co, Tl and V showed that there are effects or possibilities of anthropogenic activities. Pollution Load Index (PLI) analyses indicated all investigated sites needed further monitoring. The results of sequential extractions indicated mobile fractions (F1+F2) of Be, Tl and V were below 30% except some of Co in soil, which implies their low mobility to neighboring environment media. Variable tools like sequential extraction, comparison with background/actual concentration and pollution indices, as well as aqua regia extraction should be considered when evaluating Be, Co, Tl, V in soil.

Die vorliegende Arbeit setzte sich zum Ziel, deutsche verbale Phraseolexeme(vPL) auf der Grundlage einer Mehrebenenbeschreibung syntaktisch sowie semantisch zu untersuchen. Dabei $st\"{u}tzten$ wir uns vor allem auf die Valenz- und Kasustheorie sowie das 6-Stufen-Modell von G. Helbig(1983) und das Mehrebenenmodell $f\"{u}r$ vPL von B. Wotjak(1992), das seinerseits vom methodischen Ansatz her in engem Zusammenhang zu dem Beschreibungsansatz steht. Aber Wir modifizierten teilweise das Modell yon B. Wotjak(1992) und stellten einige vPL exemplarisch dar. Dieser Untersuchung lag eine verbozentrische Auffassung des Satzes zugrunde: Das Verb bildet das organisierende Zentrum des Satzes und ist fur die Grundstruktur des Satzes verantwortlich. Das Verb als $Valenztr\"{a}ger\;er\"{o}ffnet$ um sich herum bestimmte Leerstellen, deren Zahl und Art letztlich von der Verbbedeutung her determiniert sind. Auch vPL kann als $Valenztr\"{a}ger$ - wie das Verb - das strukturelle Zentrum des Satzes darstellen, d.h. vPL bildet als Ganzes das $Pr\"{a}dikat$, das wendungsextern eine bestimmte Zahl von Leerstellen $er\"{o}ffnet$ und determiniert im Satz mit seinen $inh\"{a}renten$ semantischen Merkmalen seine semantische und syntaktische Umgebung. Bei der Analyse von vPL gingen wir von der Auffassung von B. Wotjak aus, $da\ss$ Modelle zur Beschreibung von Verben prinzipiell auch auf die Beschreibung von verbalen PL anwendbar sind. In dieser Untersuchung verwendeten wir - in Anlehnung an B. Wotjak(1996:4f.) - den Terminus 'Phraseologismus' als Oberbegriff, der a) Kollokationen, $b)\;Funktionsverbgef\"{u}ge\;(FVG)$, c) Wortidiome (wortwertige idiomatische Redewendungen oder Phraseolexeme), d) Satzidiome(satzwertige idiomatische Redewendungen bzw. kommunikative Formeln/ Routineformeln), e) $Sprichw\"{o}rter\;umfa{\ss}t$. Wir $beschr\"{a}nkten$ uns den Gegenstand unserer Untersuchung auf verbale Phraseolexeme(vPL), d.h. wie oben genannte Wortidiome. VPL lassen sich $prim\"{a}r$ in bezug auf das wendungsexterne ($\"{a}u{\ss}ere$) Aktantenpotential(PLe) und $sekund\"{a}r$ in bezug auf die interne Kom­ponentenstruktur des PL(PLi) klassifizieren. Unsere Studie soil nicht nur Hintergrundwissen $f\"{u}r$ Lexikonein­tragungen vertiefen helfen, sondern auch $f\"{u}r$ den Fremdsprachen­unterricht von Nutzen sein.

Software internationalization, the process of making software easier to localize for specific languages, has deep implications when applied to speech technology, where the goal of the task lies in the very essence of the particular language. A greatdeal of work and fine-tuning has gone into language processing software based on ASCII or a single language, say English, thus making a port to different languages difficult. The inherent identity of a language manifests itself in its lexicon, where its character set, phoneme set, pronunciation rules are revealed. We propose a decomposition of the lexicon building process, into four discrete and sequential steps. For preprocessing to build a lexical model, we translate from specific language code to unicode. (step 1) Transliterating code points from Unicode. (step 2) Phonetically standardizing rules. (step 3) Implementing grapheme to phoneme rules. (step 4) Implementing phonological processes.

This study was performed to evaluate the possibility of inducing analgesia by electroacupuncture stimulation at single acupoint or combined acupoints and to examine the analgesic effects following the combination of premedication and electroacupunrture analgesia(EA). Analgesia was induced by EA with the current of 1-4 volts and the frequency of 10-45 Hz to the acupoints Uown to be related to analgesia on the head/necIL axial part thoracic and pelvic limb. In Yi Feng acupoint of head/neck part pain responses were not disappeared after electroacupunrture stimulation to the head/necIL thoracic limbo thoraxl abdomen, loin, rear and pelvic limb. Pain responses were remained after EA of Tian Men-Tian Ping and Shen Yu arupoints of axial park whereas hypoalgesia was observed after EA of Tian Ping-Bai Hui acupoint in all parts of body. There was no analgesic effects after EA stimulation of the brachial plexus and Wai Kuan acupoint, whereas after EA stimulation of San Yang Lo, pain responses were disappeared in headfnecll, thoracic limb and pelvic limbo and in the other parts of body hypoalgesia was shown. In EA stimulation of Tsu San Li acupoint pain responses were disappeared in pelvic limb and in San Yin Chiao acupoint pain responses were disappeared in head/necIL thoracic and pelvic limb, and hypoalgesia was shown in abdomen. On the combination of San Yang Lo Pli Men) and San Yin Chiao (Pu Yan6 acupoints, pain response in heauneck was decreased in 5 minutes, whereas analgesia in thoracic and pelvic limb was induced after 20-30 minutes and in abdomen was noted after 50 minutes. The more frequrncy was increased, the more rapid analgesic e11%t was induced. The analgesic effects wert not good in laparotomy under EA at the combination of San Yang Lo (Xi Men) and San Yin Chiao (Pu Yang) arufoints. Enteroanastomosis could not be continued under acrpromazine, xylazine and diazepam with EA. However, under EA followed by tiletaminetzolazepam, the operation could be completed without additional anesthesia and the analgesic effects were good. There were no changes in clinical signs, hematological and serological values after combination of the premeditation of tiletamine+zolaEepam and EA. It is considered that EA alone is not suitable for the main surgery, but the combination method of EA and sedatives can be utilized in practice.

In order to certificate the distribution and pollution of heavy metal of surface sediments in Nakdong River were collected and analyzed for grain size, water content, ignition loss and heavy metal content. Surface sediments mainly composed of sand(avg. 94.6%) and water content and ignition loss were 20.46%, 1.53% on average. Grain size were relatively fine and organic matter content were relatively high in the Hoichun and Sunakdonggang. Most of heavy metal content(Zn > Cr > Pb > Ni > Cu > Hg) in the Deokcheongang and Sunakdonggang were higher than the other streams. The Igeo were non polluted(less than 0) in all streams and the EF were relatively high in the small stream and PLI were non polluted(less than 1). In addition, organic matter, heavy metal content and pollution were highly correlation with grain size. Surface sediments in study area, heavy metal pollution of the Sunakdonggang were relatively high compared to the other stream but these results were not serious pollution that exceed the sediment pollution evaluation standard of river and lake in Korea and pollution levels adversely affected the majority of benthos were not.

In this study, heavy metal levels at the sediment monitoring network site upstream of the Gangjeong-Goryeong weir in the Nakdong River were surveyed from 2012 to 2016. We assessed the sediment pollution level using various pollution indexes based on ICP-MS analysis. The stream sediment pollution assessment standard, established through Regulation No. 687 of the National Institute of Environmental Research (2015), pollution load index (PLI), potential ecological risk index (RI), and mean PEL Quotient (mPELQ) were used to evaluate the sediment pollution level. We verified the representativeness of the monitoring point through the distribution of sedimentation and scour behavior by river bed surveying using anacousticDopplercurrentprofiler.

Background: Pancreatitis is a common disease in which 37% of dogs had evidence of acute or chronic pancreatitis at necropsy. Although biopsy is still the gold standard to diagnose acute pancreatitis, clinical data including ultrasonographic findings and measurement of canine serum pancreatic lipase immunoreactivity (cPLI) are used in routine. However, it may be insufficient in the diagnostic approach to acute pancreatitis. Objectives: To evaluate the clinical diagnostic feasibility of two-dimensional shear wave elastography (2D SWE) on canine acute pancreatitis for enhanced diagnostic confidence. Methods: 2D SWE was used to assess pancreatic stiffness and determine the correlation between pancreatic shear wave velocity (SWV) and Spec cPL concentration in 31 dogs with healthy pancreas and 10 dogs with acute pancreatitis. Results: The pancreatic SWV was significantly higher in the acute pancreatitis group (2.67 ± 0.20 m/s) than in the healthy pancreas group (2.30 ± 0.26 m/s; p < 0.05). The moderate positive correlation was found between the pancreatic SWV and Spec cPL concentration (95% confidence interval, 0.214-0.693; r = 0.489; p < 0.05). Conclusions: These results indicated that 2D SWE was feasible for assessing pancreatic stiffness in acute pancreatitis, and that pancreatic SWV using 2D SWE correlated with Spec cPL concentration. SWE could provide a quantitative measure of pancreatic stiffness, which can increase the accuracy of diagnosing acute pancreatitis in dogs. The 2D SWE can be used as a complementary imaging modality for diagnosing acute pancreatitis in dogs.

The concentrations of trace metals and organic matters in marine sediments collected from southeast Korean coastal areas were investigated. The primary purpose of this study was to evaluate the contamination status, spatial distribution and potential ecological risks associated with the physiochemical composition in the studied areas. We found that the concentrations of trace metals in marine sediments were as follows: Fe > Mn > Zn > Cr > Pb > Cu > As > Cd > Hg. According to the sediment quality guidelines (SQGs) of Korea, concentrations of Zn, Cr, Cu and Cd at all sampling sites were below threshold effect levels (TEL). However, concentrations of As, Hg, and Pb (i.e., at the 94-98% of sampling sites), were below the TEL. In addition, concentration factors (CF) in the surveyed area were found to be associated with low ecological risks, whereas As, Hg, and Cu showed moderate to high risk levels in some inner parts of the studied bays. Finally, the pollution load index (PLI) and ecological risk index (ERI) of the elucidated metals were linked to moderate ecological risk, pointing to the possibility of being deleterious to some benthic organisms.
