The aim of this study was to identify the bacteria isolated from endodontic lesions by cell culture and to determine the antimicrobial susceptibility of them against 8 antibiotics. The necrotic pulpal tissues were collected from 27 infected root canals, which were diagnosed as endodontic infection. Samples were collected aseptically from the infected pulpal tissue of the infected root canals using a barbed broach and a paper point. The cut barbed broaches and paper points were transferred to an eppendorf tube containing $500{\mu}l\;of\;1{\times}PBS$. The sample solution was briefly mixed and plated onto a BHI-agar plate containing 5% sheep blood. The agar plates were incubated in a $37^{\circ}C$ anaerobic chamber for 2 to 5 days. The bacteria grown on the agar plates were identified by comparison of 16S rRNA gene (rDNA) sequencing method at the species level. To test the sensitivity of the bacteria isolated from the infected root canals against 8 antibiotics, minimum inhibitory concentrations (MIC) were determined using broth dilution assay. The data showed that 101 bacterial strains were isolated and were identified. Streptococcus spp. (29.7%) and Actinomyces spp. (21.8%) were predominantly isolated. The 9 strains were excluded in antimicrobial susceptibility test because they were lost during the experiment or were not grown in broth culture. The percentage of bacteria susceptible for each antibiotic in this study was clindamycin, 87.0% (80 of 92); tetracycline, 75.0% (69 of 92); cefuroxime axetil, 75.0% (69 of 92); amoxicillin + clavulanic acid (5:1), 71.7% (66 of 92); penicillin G, 66.3% (61 of 92); erythromycin, 66.3% (61 of 92); amoxicillin, 44.6% (41 of 92); and ciprofloxacin, 31.5% (29 of 92). The susceptibility pattern of 8 antibiotics was dependent on the host of the bacteria strains rather than the kinds of bacterial species. These results indicate that antibiotic susceptibility test should be performed when antibiotics are needed for the treatment of infected root canals.

This study is trying to analyze why the service industry is important. The service industry can change the structure of manufacture-oriented industry and accomplish the green growth in Korea. It explained how the change of domestic and foreign environment has the effect on the service and manufacture industry. And the Climate Change is likely to have the negative effects on the korean companies. Some of the service industries can help those companies minimizing risk caused by Climate Change. Those service industries are defined as green service industry including consulting service, financial service, IT service and meteorological service. But the policy about consulting service, financial service, IT service and meteorological service is still not enough despite they are important in minimizing the corporate risk related to climate change. The government has to make the policy to foster those green service industries as soon as possible.

This paper is trying to analyze the relationship between non-conditional grants and local expenditures. There are two hypotheses to explain them. One is that the non-conditional grants has the positive effect on the local governmental expen-ditures. Another is that the share of non-conditional grants to the revenue has the positive relationship with the expenditures as a percentage of resident income in local governments. So the local expenditure function and the function of the share of the local expenditure to resident income have to be estimated . The first result shows that the response of local expenditures by the increase of non-conditional grants is greater than by local income. This is called the flypaper effect of non-conditional grants on the local expenditures. The second result explains that the share of non-conditional grants to the revenue can expand the share of the local expenditures to resident income. From the results, it is deduced that the non-conditional grants can be one of the reasons why the local expenditures increase very fast in Korea.

Purpose To prospectively assess the safety and effectiveness of computed tomography(CT)-guided marking using a wire before video-assisted thoracoscopic surgery for small pulmonary nodules, with characteristics and excision methods of pulmonary nodule suspicious to primary lung cancer. Materials and methods For June 2008 to July 2009, 35 patients(13 men, 22 women; range 34-75, mean age, 56 years) with Surgical removal for small pulmonary nodules were included in prospective study. With 4 channel CT scanner, the guided material was used 10 mm long, 21 gauge spring-hook type wire. Results The average CTDIVOL, effective close for each procedure were 7.80⊕3.16 mGy, 3.71⊕1.4 mSv respectively. Needle tip were completely targeted in nodule at 12(34.3%) out of 33 persons, at 13 persons(37%) into the direction of pleura and at 10 persons(28.6%) into the parenchyma rather than nodule. The mean diameter of the nodules, measured by CT scans, was 10.2⊕4.9 mm and ranged 0.3 mm to 2.8 mm. The distance of the nodules to visceral of pleura was 16.3⊕7.7 mm and ranged 4mm to 35 mm. From lesion characteristics of ground-glass opacity, pathological findings of adenocarcinoma was 29(82.8%). Metastatic cancer and immflamation were 3 persons (8.6%) respectively. In the procedure there was no complication in 19 persons(57.1%). tiny pneumothorax and hemorrhage were 13 persons(37.1%) and 2 persons(5.8%) respectively. And additional intervention was not required. Conclusion CT-guided marking wire procedure was very efficient with low radiation close, and minimizing to patients unrest in terms of low complications and simple procedure. Also it was useful study which could help minimizing resection of lung parenchyma including the nodule.

This paper explains if the relationship between the air cargo and exchange rate is proportional or not. Two explanatory variables(real exchange rate and U.S. Industrial Production Index) are used to estimate the Korea air cargo function. At first, the cointegration test derives a long-term equilibrium relationship among these three variables. So the model to be estimated has to be the Error Correction Model to represent this cointegration relationship. The result shows that the U.S. Industrial Production Index has the proportional relationship with the air cargo in the short-and long-term. But it is proven that the air cargo decreases if the exchange rate increases in the short-and long-term.

Young people live in a rapidly changing universe dominated by information technologies. Parents and educators need to become familiar with new technologies and media so that they can adequately supervise young people`s use of them. As is true of any form of communication, electronic media can be abused. Cyberbullying is an important concern for teachers and parents. Estimates of the prevalence of cyberbullying vary. One credible estimate is that 9% of youth ages 9-17 who use the internet are cyberbullied each year in U.S.. Another is that about 13% of preteens and teenagers occasionally behave aggressively in online cyber space. The distance and potential anonymity of cyber space communication may increase its potential to be used for bullying. The likelihood of students being cyberbullied increases as they spend more time online and as they cyberbully others. A victim is more likely to experience stress from online bullying if he or she is younger than the perpetrator, is asked to send a digitized photo of their own, or is also at risk of physical confrontation with the bully. Some online confrontations have led to verbal and physical confrontations at school. A school`s anti-bullying policy and computer use policy should both prohibit cyberbullying. Adults should closely monitor the internet use of younger``s, and teach them how to behave safely and responsibly while they are in cyber space. Teachers should make it clear to them that misconduct online is no more acceptable than misbehavior in the face-to-face world. Schools should encourage parents to be part of this efforts. The whole system of educational processes should be implemented through 3 steps approach. First step, everyone have to admit the extent of problem. Second step, awareness sharing is important. Third step is implementation of educational and preventive programs.
