According to the nationwide survey of tuberculosis from 1965 to 1995, the incidence and drug resistance rate of tuberculosis have been decreased in Korea, but the prevalence of multidrug resistance of Mycobacterium tuberculosis is still a serious problem. The purpose of this study is to investigate the drug resistance rate and pattern of tuberculosis in Daejeon from 2001 to 2008. Of the total 581cases where the drug susceptibility test was performed, resistance to at least one anti-TB drug was found in 104 cases(17.9%) of these, 68(11.7%) were resistant to at least INH and 41(7.1%) were resistant to at least RFP. Single-drug resistance was found for isolates from 37(6.4%) ; 18(3.1%) of these were resistant to INH and 5(0.9%) to RFP. Multidrug resistance, where TB was resistant to at least isoniazid and refampin, was found in 35 cases(6.0%). and Factors associated with MDR-TB included age under 40-60.The drug-resistance rate of pulmonary TB, especially MDR-TB, is higher in the initial treated patients at a private referral hospital than in those in the pubulic sector. Initial drug resistance is common and the drug susceptibility test is informative for pulmonary TB patients who have not received previous TB treatment. The need for an improved control program, coupled with early diagnosis of MDR-TB, to reduce the spread and development of resistance. Multidrug resistance rate is still problem in korea. Efforts to decrease multidrug resistance rate either independently or in cooperation with the pubulic sector will be needed.

The study performed questionnaire to the patients receiving implant operation, who visited dental clinics and hospitals(2 hospitals and 5 clinics) from Jul. 1, 2009 to Sep. 12, 2009 in order to study the factors giving effects to patient's satisfaction in the selection of implant. 145 questionnaire papers collected from patients were analyzed with SPSS12.0 program. The result revealed that the satisfaction with implant operation was usually normal when implant was operated because of tooth extraction due to dental caries and periodontal disease and it was usually high when implant was operated because of wound(P<0.05). When considering each cause of tooth extraction, the satisfaction with pronunciation function was usually normal(P<0.001), the satisfaction with functional part including foreign body sense was very low when the cause of operation was periodontal disease(P<0.01). The satisfaction with hospital environment depending on the cause of hospital selection was usually high when hospital was selected because of doctor's fame. It was low when hospital was selected because it was close to home(P<0.001). The satisfaction with the number of hospital visits depending on the number of implanted teeth was usually low when many teeth were implanted(P<0.01). The analysis on the satisfaction with tooth shape and color showed that the satisfaction was high when '1~2' teeth and 'more than 6' teeth were implanted(P<0.05). In order to improve patient's satisfaction with implant, it is necessary to recognize individual's oral status and request correctly. It is determined that proposal of operation period, number of hospital visits, function and expected aesthetic satisfaction degree will contribute to the improvement of mutual reliance between doctor and patient and post-operation satisfaction degree.

Purpose: The Korean society has moved rapidly toward becoming a multicultural society. This study aimed to estimate the seroprevalence of hepatitis viruses and investigate hepatitis B virus (HBV) genotypic diversity in female marriage immigrants. Materials and Methods: Screening program was conducted at support centers for multicultural families in 21 administrative districts in Korea between July 2011 and January 2017. A total of 963 female marriage immigrants were included in this study. Blood samples were tested for hepatitis viral markers and HBV genotype. Results: Subjects' median age was 33 years (20-40 years), and they originated from nine countries including Vietnam (n=422, 43.8%), China (n=311, 32.3%), the Philippines (n=85, 8.8%), Cambodia (n=58, 6.0%), and Japan (n=39, 4.0%). About 30% (n=288) of subjects required hepatitis A vaccination. HBsAg positive rate was 5.4% (n=52). Positive HBsAg results were the highest in subjects from Southeast Asia (6.6%, n=38). Anti-HBs positive rate was 60.4% (n=582). About 34% (n=329) of subjects who were negative for anti-HBs and HBsAg required HBV vaccinations. Genotypes B and C were found in 54.6% (n=12) and 45.4% (n=10) of the 22 subjects with HBV, in whom genotypes were tested. Eight (0.8%) subjects were positive for anti-HCV. Positive anti-HCV results were the highest in subjects from Central Asia (7.9%, n=3). Conclusion: Testing for hepatitis viral marker (hepatitis A virus IgG and HBsAg/anti-HBs) is needed for female marriage immigrants. Especially, HBV genotype B is different from genotype C of Koreans. Therefore, interest and attention to vaccination programs for female marriage immigrants are necessary for both clinicians and public health institutes.

College students face serious difficulties while seeking jobs, leading to a high degree of stress, which is thought to affect their attitude towards smoking. The purpose of this study was to identify the relationship between hardiness, job-seeking stress, and the attitude towards smoking among students, and to further identify the factors influencing smoking attitude. Data were collected using a structured questionnaire administered to 145 students. Data analysis was performed using the SPSS program, t-test, ANOVA, Kruskal Wallis test, Pearson's Correlation Coefficients, and hierarchical multiple regression analysis. Smokers constituted 22.1% of the sample. The study showed that smoking attitudes varied according to the smoking status (H=28.26, p<.001). The smoking attitude was seen to be desirable in the high group (t=-3.27, p=.001) and low job-seeking stress group (t=4.40, p<.001). There was a positive correlation between hardiness and smoking attitude (r=.18, p=.028). There was a negative correlation between job-seeking stress and smoking attitude (r=-.28, p=.001). Also, the factors affecting the smoking attitude were non-smoker respondent (β=.50, p<.001), job-seeking stress (β=-.23, p=.015), former smoker respondent (β=.22, p=.016) and the explanatory power was 24.3%. Therefore, school and health public center counseling and employment support programs need to help students manage and cope with stressful situations to change their attitude towards smoking in a desirable direction.

As a link of chain study program of school health, a survey was made up by the screening test with audiometry for hearing disturbance on 18,675 high school students who are mainly aged in 15-19 years from November 5.1969 to October 30. 1970. The results obtained were summerized as follows. According to our criteria as table 3, the rates of the profound, the severe and the moderate who required the appropriate hearing aids were 0.02%, 0.03% and 0.14% respectively:-the cumulative percentage was 0.197. When the marginal, 0.23% should be included the cumulative rate was 0.41%. But there was no-significance by sex and school classes. If we will make the special classes for them one class would be estimated out of 10,000 persons when a class is formed with about 15 persons. Otherwise when we examined that according to each ear of persons, the rates of the profound, the severe and the moderate were 0.17%, 0.22% and 0.33% respectively and their cumulative percentage wag 0.72. There was no significance also by sex and age. By the way, the rate of hearing disturbance in urban high school students tended to lower than rural. And the perceptive disturbance was higher than rural in rate. The conductive disturbance tended to oppose in comparison with the above.
