To investigate patterns and severity of hunting-related emergency traumatic injuries in wild boar hunting dogs. One hundred wild boar hunting dogs with emergency traumatic injuries sustained during wild boar hunting as a result of wild boar attack and accidental shooting of ensnarement in a trap. The retrospective study involved 100 dogs brought to CAMC for treatment of emergency traumatic injury sustained during wild boar hunting in Jeon-buk province from August 2007 to April 2008. Medical information obtained from the medical records included signalment; cause of injury; number, location and severity of injuries; and mortality. The 100 patients displayed 136 injuries (single injury in 71 dogs and multiple injuries in 29 dogs). Causes of the emergency traumatic injuries were wild boar attack (n = 92), accidental shooting (n = 7), and entrapment (n = 1). The thoracic area was the most common site of injury. The most common injury severity score (ISS) was code 2. The mortality rate was 9%, and all deaths involved thoracic injury. Emergency traumatic injuries sustained during wild boar hunting are most commonly thoracic injuries caused by prey attack. The nature of the injuries can differ from those typically encountered by small animal veterinarians.

Purpose: The aim of this study is to investigate the change in incidence and clinical characteristics of acute poststreptococcal glomerulonephritis (APSGN) through a single center's experience. Methods: We retrospectively analyzed the medical records of 53 children who were diagnosed with glomerular nephritis at National Health Insurance Corporation Ilsan Hospital between March 2000 and December 2009. Twenty-six of 53 patients falled to meet the dragnostic criteria of APSGN and were excluded. Chief complaints, physical examinations, urinalysis, urine culture, laboratory results, chest x-ray, and clinical manifestations were all retrieved from the remaining 27 patients. Results: The incidence of APSGN by age was highest in children between six to seven years of age, with similar distributions in both genders, and seasonal incidence was higher from November to February when compared to other months, which was similar to the previously reported studies. However, the annual number of APSGN patients did not show a significant decrease from 2000 to 2009. The incidences of edema and hypertension were 59.3% and 48.1% respectively, suggesting lower incidences than those from previous studies. Six patients (22.2%) experienced hematuria for more than 6 months. Hypertensive encephalopathy, one of APSGN critical complications occurred in one patient but resolved with conservative treatment. Conclusion: Our study shows that APSGN still occur as a common renal disease but the disease severity seems to decrease with milder clinical manifestations and less complications compared to past studies.

To mitigate the impacts of climate change on agricultural ecosystems, development of agricultural management for enhanced soil carbon sequestration is required. In this study, the effects of fertilizer types (chemical fertilizer and manure compost), cropping systems, and crop residue management on SOC(Soil Organic Carbon) sequestration were investigated. Summer corn and winter barley were cultivated on experimental plots under natural rainfall conditions for two years with chemical fertilizer and manure compost. Soil samples were collected conducted and analyzed for SOC for soil. To estimate long-term variation patterns of SOC, DNDC was run with the experimental data and the weather input parameters from 1981 to 2010. DNDC simulation demonstrated SOC reduction by chemical fertilizer treatment unless plant residues are returned; whereas compost treatments increased SOC under the same conditions and SOC increment was proportional to compost application rate. In addition, SOC further increased under corn-barley cropping system over single corn cropping due to more compost application. Regardless of nutrient input type, residue return increased SOC; however, the magnitude of SOC increase by residue return was lower than by compost application.

Effects of incompatibility existing between intra-and interspecies in Pleurotus spp. on protoplast fusion, clamp formation of their fusants and fruitbody production were investigated. Protoplast fusion between intra-and interspecies of the fungus was achieved by Poly ethylene glycol treatment. The fusion frequency between intraspecies was a little higher than that of interspecies. Fusion frequency between interspecies was not correlated with their similarities based on isozyme patterns. In case of protoplast fusion between intra-and interspecies, the fusants from the compatible isolates produced normal fruit bodies, while those from the incompatible isolates did not produce clamp connections and fruit bodies except those of a few isolates presumed mutants.

Optimal orthodontic treatment could be possible when a orthodontist can predict and control tooth movement by applying a planned force system to the dentition. The moment to force(M/F) ratio at the bracket, has been shown to be a primary determinate of the pattern of tooth movement. As various n/F ratios are applied to the bracket on the tooth crown, strain distribution in periodontium can be changed, and the center of rotation in tooth movement can be determined. It is, therefore, so important in clinicalorthodontics to know the strain distribution in a force system of a M/F ratio. The purpose of this study was to analyze the strain distribution in orthodontic force system by strain gauge attached to tooth root, and to evaluate the usage of the method. For this study, an experimental upper anterior arch model was constructed, where upper central incisors, on the root surface of which, 8 strain gauges were attached, were implanted In the photoelastic resin, as in the case of 4mm midline diastema. Three types of closing of upper midline diastema closure were compared : 1. with elastomeric chain(100g force) in no arch wire, 2. elastomeric chain in .016“ round steel wire, 3. elastomeric chain in .016”x.022“ rectangular steel wire. The results were as follows. 1. Strain distributions on labial, lingual, mesial and distal root surface of tooth were able to be evaluated with the strain gauge method, and the patterns of tooth rotation were understood by presuming the location of moment arm. 2. Extrusion and tipping movement of tooth was seen in closing in no arch wire, and intrusion and bodily movement was seen with steel arch wire inserted.

Robinow syndrome is skeletal dysplasia with both autosomal dominant and recessive inheritance patterns. It is characterized by short-limbed dwarfism, abnormalities in the head and face, as well as vertebral segmentation. A 2-year-7-month old boy with Robinow syndrome had visited Seoul National University Dental Hospital, for the evaluation of tooth palatal eruption on maxilla. He had micrognathia, delayed tooth eruption, cleft lip with bifid uvula. He also had an erupted mesiodens on the palatal side of maxillary primary incisors, which was tuberculated and 8mm in major diameter. The patient was scheduled for mesiodens extraction under general anesthesia. He was a young child with delayed development, so general anesthesia was inevitable. General anesthesia was induced and maintained with inhalation agent, Sevoflurane. There were no postoperative complications related to anesthesia and dental treatment. Robinow syndrome patients have craniofacial dysmorphism and eruption disorders. Therefore, he requires regular check-ups as well as dental managements.

The dissipation patterns of amisulbrom in cucumber under a greenhouse condition was investigated to establish biological half-life and pre-harvest residue limit (PHRL). Amisulbrom residue in/on cucumber on the day of application under standard application condition was $0.15mg\;kg^{-1}$ and decreased to $0.06mg\;kg^{-1}$ after 5 days after treatment, so that biological half-life calculated 3.6 day, while initial concentration of amisulbrom twice application 3 days interval under standard application condition was $0.35mg\;kg^{-1}$ and decreased to $0.09mg\;kg^{-1}$ after same period and the biological half-life calculated 2.4 day. PHRL was suggested by prediction curve calculated from the decay constant of amisulbrom at standard rate. For example, $1.83mg\;kg^{-1}$ at 5 days before harvest and $1.03mg\;kg^{-1}$ at 2 days before harvest were suggested.

For determining the insecticidal effect of Carbofuran on the Brown planthopper, Nilaparvata lugens, sucking toxicity by drenching application, sucking and contact toxicity by leaf dipping application, and contact toxicity by topical application were examined. Drenching caused two types of mortality patterns. One was logarithmic curve at a relatively high concentration (8~30 ppm) with over 40% mortality in 24 h, and the other was an S-shaped curve at low concentrations (1~4 ppm) with over 60% mortality on the fifth day after Carbofuran treatment. Leaf dipping application caused a rapid increase in mortality in a day, and this effect decreased steadily with time. Topical application showed steep increase in mortality in a day, and hardly increased thereafter. The best mortality evaluation time for the drenching application was the second day (42 h), and that for the leaf dipping and topical applications was the first or second day after Carbofuran application. When the insecticide has systemic effects, drench application provides the best efficacy and its insecticidal effects persist for a longer time than any other application method.

Total bacterial community DNA, which was extracted from microcosm soil and field soil after 2,4-D amendments, was analyzed on Southern blots, using the tfdA gene probe derived from plasmid pJP4 and the Spa probe from Sphingomonas paucimobilis. Southern blot analyses with total bacterial DNA extracted from soils Inoculated with Pseudomonas cepacia/pJP4 revealed that DNA probe method could detect the 2,4-D degrading bacteria down to $10^5\;cells/g$ dry soil. In the microcosm experiment, there was a good correlation between 2,4-D degradation and banding patterns in hybridization analyses performed after each 2,4-D treatment using the two probes. When bacterial DNA extracted from microcosm soil was hybridized with the Spa probe, a change in the position of hybrid bands was observed over time in a Southern blot, suggesting that population change or possibly genetic rearrangement in 2,4-D degrading microbial populations occurred in this soil. With the Spa probe, one hybrid DNA band was persistently observed throughout the five 2,4-D additions. When bacterial DNA isolated from the field soil was probed with the tfdA and Spa, strong hybridization signal was observed in the 100 ppm-treated subplot, weak signal In the 10 ppm-treated subplot, and no significant signal in the 1 ppm-treated and control subplots. The data show that DNA probe analyses were capable of detecting and discriminating the indigenous 2,4-D degrading microbial populations in soil amended with 2,4-D under laboratory and field conditions.

Patients tend to return to normal pronunciation patterns after fitting new dentures. However, for some patients, it takes a long time to adapt the new complete denture. In this case, the patient came to the hospital at the address of wanting to remake dentures due to wear and tear. After diagnosis through clinical and radiological examination, the maxillary complete denture and mandibular removable partial denture were remade. The patient complained whistling /s/ sound at the first check-up after placement of the new denture. The anterior palatal area of polished surface of the new maxillary complete denture was concave comparing to old denture, and this was the cause of the whistling /s/ sound. A tissue conditioning material was applied to the maxillary complete denture and patient made /s/ sound. The tissue conditioning material was replaced with self-curing type denture base resin, and the patient was immediately satisfied with clear /s/ sound. As an objective assessment, palatogram and speech analytics software was applied. In this case, a patient who received denture treatment complaining of difficulty in pronunciation underwent immediate denture repair, which resulted in patient satisfaction and improved pronunciation through objective evaluation.
