We investigated 52 livestock farming complexes in Gyeong-Gi and Incheon provinces based on low, medium, and high livestock density and groundwater quality. The objective of this study was to evaluate a relationship between nitrate N concentration in groundwater and animal factors, such as livestock density and animal species. 2,200 groundwater samples for 3 years from 2012 to 2014 at Gyeong-Gi and Incheon provinces were collected and analyzed for pH, EC, DO, ORP, temperature, major anions and cations, such as NO₃-N, HCO₃<SUP>-</SUP>, PO₄<SUP>-</SUP>, SO₄<SUP>2-</SUP>, Cl<SUP>-</SUP>, NH₄-N, K<SUP>+</SUP>, Na<SUP>+</SUP>, Ca<SUP>2+</SUP>, Mg<SUP>2+</SUP>, T-N, and TOC. Average concentration of total N for generated load density was 23,973 g day<SUP>-1</SUP> km<SUP>-2</SUP> for cattle, 51,551 g day<SUP>-1</SUP> km<SUP>-2</SUP> for pig, and 52,100 g day<SUP>-1</SUP> km<SUP>-2</SUP> for poultry. For animal feeding species, average ratio for generated load over discharge load was 16.1% for cattle, 7.8% for pig, and 7.1% for poultry. Therefore, cattle feeding region is highly vulnerable for water pollution compared to pig and poultry feeding areas. The concentrations of chloride, nitrate, and total N in the groundwater samples were higher at high animal farming regions than other regions. The average concentration of nitrate, and chloride in groundwater samples was 5.0 mg L<SUP>-1</SUP>, 16.6 mg L<SUP>-1</SUP> for low livestock density, 6.9 mg L<SUP>-1</SUP>, 17.7 mg L<SUP>-1</SUP> for medium livestock density and 7.6 mg L<SUP>-1</SUP>, 22.7 mg L<SUP>-1</SUP> for high livestock density and total nitrogen (T-N) was 7.7 mg L<SUP>-1</SUP> for low livestock density, 9.4 mg L<SUP>-1</SUP> for medium livestock density, 10.7 mg L<SUP>-1</SUP> for high livestock density. In conclusion, based on this research, for managing groundwater quality near livestock farming regions, Ca-(Cl+NO₃) group from the Piper diagram is more efficient than using 19 factors for water quality standard.

Average concentration of total N for generated load density was $23,973g\;day^{-1}\;km^{-2}$ for cattle, $51,551g\;day^{-1}\;km^{-2}$ for pig, and $52,100g\;day^{-1}\;km^{-2}$ for poultry.

Objective: The Objective of this study was to assess the positive culture rate and antimicrobial susceptibilities of Mycoplasma hominis (MH) and Ureaplasma urealyticum (UU) in general population and pregnant women. Methods: We reviewed a retrospective medical records of patients who have undergone culture test and antimicrobial susceptibilities at our center from April 2018 through January 2017. The study included all patients with positive culture for MH, UU or both. Results: The condition was assessed in 200 patients. All of them, 34 (17%) were pregnant women and 166 (83%) were non-pregnant women. From 105 (52.5%) out of total 200 had a positive culture as follows: MH 46 (23%), UU 95 (47.5%) and both 36 (18%). Susceptibilities of MH to doxycycline, erythromycin, ciprofloxacin, and azithromycin were 97.8%, 6.5%, 17.4%, and 8.7%, respectively. Susceptibilities of UU to doxycycline, erythromycin, ciprofloxacin, and azithromycin were 95.8%, 55.8%, 7.4%, and 56.8%, respectively. Susceptibilities of both MH and UU to doxycycline, erythromycin, ciprofloxacin, and azithromycin were 97.2%, 5.6%, 11.1%, and 11.1%, respectively. Conclusion: UU was the leading causative pathogen for genitourinary infection in our study. MH accounted for about half of the UU infection rate. Doxycycline was still best susceptible to UU, MU, and both. Ciprofloxacin had less than 20% susceptibility to MU, UU, both. The major problem is that the pregnant women is infected with MU and both are not sensitive to erythromycin and azithromycin at all.

Small bowel perforation in the postpartum period is very rare and is often misdiagnosed as functional paralytic ileus after surgery or pain at the wound, rapid and accurate diagnosis can be very difficult and delayed for various reasons, which can threaten the life of the mother. In the past 10 years, we have had experienced two cases of duodenal ulcer perforation after cesarean section. In all two cases, there was no past history of the ulcer, the first case was too severe and laparotomy after laparoscopic attempt was performed, and the second case was treated laparoscopic surgery by 3-0 V-LocTM absorbable wound closure device. In case of unexpected abdominal pain, especially in the case of accompanying fever during well recovery 4-7 days after cesarean section, if the surgical site is normal, the gastrointestinal disorder should be considered.

Objectives The Purpose of this study is to evaluate the clinical effectiveness of cotreatment with Chuna Manual Therapy for Diffuse Idiopathic Skeletal Hyperostosis. Methods The patient treated by Chuna Manual Therapy for 14days. Treatmental effects were measured by using the Verbal Numeric Rating Scale(VNRS), Neck Disability index(NDI) and Cervical spine Range of Motion(C-spine ROM). Results VNRS decreased 8 to 3, NDI also reduced 44 to 20, and Cervical spine Range of Motion was improved Flexion 5°, Extension 5°, Lat.bending 5°/5°, Rotation 10°/10° to Flexion 30°, Extension 30°, Lat.bending 4 0°/40°, Rotation 60°/60° after Chuna Manual Therapy. Conclusions Cotreatment with Chuna Manual Therapy can be effective treatment for a patient with Diffuse Idiopathic Skeletal Hyperostosis. Further clinical studies are needed to verify the findings.

Objectives: The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). Methods: An oral examination as part of The National Health and Nutrition Examination was proposed to calculate the sample design and survey participation. The surveying system was presented by classifying the measurement environment, screening, and survey items by year, and the merits and limitations of using the data were suggested by examining the status of survey quality management and the process of disclosing raw data. Results: This nationally representative cross-sectional survey samples approximately 10,000 individuals each year and collects information on oral examinations and oral health interviews. Data for the oral health component of KNHANES was obtained to assess the oral health status of Koreans and determine the prevalence of dental caries and periodontitis. The oral health data quality control of KNHANES was composed of three parts: “Education Program” and “Field Training Program” for quality control of oral health examiners (dentists) by the professional academy, and “Data management” by the KCDC. After completion of the three-step data check, the indicators of dental caries, periodontal disease, and oral health behavior were published in the National Health Statistics. Conclusions: To achieve the goals of oral health indicators, we will continue to monitor so that we can use it as basic data for oral policies and carry out various linkage analyses related to oral diseases.
