Objectives: We wanted to estimate the annual socioeconomic costs of alcohol drinking in Korea. Methods: The costs were classified as direct costs, indirect costs and the other costs. The direct costs consisted of direct medical costs, indirect medical costs and subsidiary medical costs. Particularly, the medical costs and population attributable fraction for disease were considered to reflect the calculation of the direct medical costs. The indirect costs were computed by the extent to which the loss of productivity and loss of the workforce might have occurred due to changes in mortality and morbidity according to alcohol drinking. The other costs consisted of property loss, administration costs and costs of alcoholic beverage. Results: The annual costs, which seemed to be attributable to alcohol drinking, were estimated to be 149,352 hundred million won (2.86% of GDP). In case of the latter, the amount includes 9,091 hundred million won for direct costs (6.09%), 62,845 hundred million won for the reduction and loss of productivity (42.08%), 44,691 hundred million won for loss of the workforce (29.92%), and the other costs (21.91%). Conclusions: Our study confirms that compared with the cases of Japan (1.9% of GNP) and the other advanced countries (1.00-1.42% of GDP), alcohol drinking incurs substantial socioeconomic costs to the Korean society. Therefore, this study provides strong support for government interventions to control alcohol drinking in Korea.

Objectives: The purpose of this study was to examine the effect of women's late age of marriage on the interval between marriage and their first birth Methods: Data from Year 2000 Korea National Fertility Survey was collected through direct interview questionings, and the data was analyzed based on randomly selected sampling. In particular, the married women (N=5,648) were analyzed for the factors that determined the first-birth interval by performing Cox's proportional hazard model survival analysis. Results: Unlike previous findings, the woman whose age of marriage was 30 or more was more likely to delay the birth of her first baby than were the other women who married earlier. Further, a woman's age at marriage, a woman's residence before marriage, her husband's religion, her husband's level of education and the difference in age between the woman and her husband significantly influenced the first-birth interval. In contrast, for a married woman, her age, level of education, current residence and religion were not significant predictors of her first birth interval. Conclusions: Our study showed that women who married at the age of 30 years or more tend to postpone their first birth in Korea. When facing the increasing number of women who marry at a late age, the Korean government should implement population and social policies to encourage married women have their first child as early as possible.

어린이와 청소년을 대상으로 한 치과 진정법에서 환자 안전과 성공의 열쇠는 호흡기 상태와 밀접하게 연관되어 있다. 소아치과의 특별한 상황 - 똑바로 누운 자세에서 러버댐으로 구강 측 기도가 제한 된 상태-하에서 코로 호흡함을 고려해야 한다. 따라서 소아치과의사는 의과적 자문이나 평가와 별도로, 스스로 이러한 상황하에서 환자의 호흡기적 평가를 할 필요가 있다. 특히, 아데노이드 비대, 코막힘, 후비루와 기도과민 등의 상황을 평가하는 것이 중요하다. 부비동염, 알레르기 비염, 천식, 코골이와 폐쇄성 수면 무호흡 증후군 등이 있는 환자는 진정 실패를 초래할 가능성이 있으므로, 질환이나 증상에 대한 확실한 조절을 통하여 치과 진정법의 안전성을 더욱 증진 시킬 수 있을 것이다. The safety and success of dental sedation for children depend mainly on respiratory status of patients. A special condition, that is, nasal breathing in supine position with their oral airway blocked by rubber dam, should be considered. Therefore, irrespective of medical consultation, pediatric dentists themselves should do respiratory assessment especially adenotonsillar hypertrophy, nasal obstruction, posterior nasal drainage and airway hypersensitivity. Patients with sinusitis, allergic rhinitis, asthma, snoring and OSAS(obstructive sleep apnea syndrome) can induce the sedation failure and complete management of these can improve the safety of dental sedation.

Objectives: To determine the impact of cigarette prices on the decision to initiate and quit smoking by taking into account the interdependence of smoking and other behavioral risk factors. Methods: The study population consisted of 3,000 male Koreans aged ${\ge}20$. A survey by telephone interview was undertaken to collect information on cigarette price, smoking and other behavioral risk factors. A two-part model was used to examine separately the effect of price on the decision to be a smoker, and on the amount of cigarettes smoked. Results: The overall price elasticity of cigarettes was estimated at -0.66, with a price elasticity of -0.02 for smoking participation and -0.64 for the amount of cigarettes consumed by smokers. The inclusion of other behavioral risk factors reduced the estimated price elasticity for smoking participation substantially, but had no effect on the conditional price elasticity for the quantity of cigarettes smoked. Conclusions: From the public health and financial perspectives, an increase in cigarette price would significantly reduce smoking prevalence as well as cigarette consumption by smokers in Korea.

토착 미생물을 이용한 MTBE와 BTEX의 혐기성 생분해 연구

정우진,장순웅,Chung, Woo-Jin,Chang, Soon-Woong 한국지하수토양환경학회 2016 지하수토양환경 Vol.21 No.3

The simultaneous biodegradation between MTBE (Gasoline additives) and BTEX (Benzene, Toluene, Ethyl-benzene, o-Xylene, m-Xylene, p-Xylene) was achieved within a competitive inter-relationship, with not only electron accepters such as nitrate, sulfate, and iron(III) without oxygen, but also with electron donors such as MTBE and BTEX. Preexisting indigenous microorganisms from a domestic sample of gasoline contaminated soil was used for a lab-scale batch test. The result of the test showed that the biodegradation rate of MTBE decreased when there was co-existing MTBE and BTEX, compared to having just MTBE present. The growth of indigenous microorganisms was not affected in the case of the MTBE treatment, whereas the growth of the microorganisms was decreased in combined MTBE and BTEX sample. This may indicate that an inhibitor related to biodegradation when BTEX and MTBE are mixed will be found. This inhibitor may be found to retard the anaerobic conditions needed for efficient breakdown of these complex carbon chain molecules in-situ. Moreover, it is also possible that an unknown competitive reaction is being imposed on the interactions between MTBE and BTEX dependent on conditions, ratios of mixture, etc.

Objectives : The purpose of this study was to estimate the willingness to quit cigarette price among Korean male adults, and to examine the factors affecting the willingness to quit cigarette price. Methods : The data was collected by a random digit dial telephone survey. 702 samples were analyzed by using t-tests, ANOVA and OLS regression analysis. To estimate the willingness to quit cigarette price, smokers were asked dichotomous questions with open-ended follow-up and the starting point of the price was randomized by one of 5 bid prices elicited from a pilot study. Results : The mean of the willingness to quit cigarette price was 4,287 Won per package, which was about 2,000 Won higher than the mean of the actual price the smokers now paid. About 41% of respondents were willing to quit smoking if the price of cigarette would be increased by 3,000 Won, and if the price would be increased by 20,000 Won, all respondents were willing to quit smoking. The factors associated with the willingness to quit cigarette price were the place of residence, the amount of smoking and the degree of exposure to smoking through the mass media. Conclusions : The results showed that to get people to quit smoking, increasing the cigarette price would obviously be effective and much higher prices have a greater effect. Furthermore, to enlarge the effect of increased cigarette prices, providing more cessation programs to small towns, reducing the amount of smoking and decreasing or prohibiting advertisements of cigarettes and smoking in the mass media will be efficient.

Purpose: Human metapneumovirus (hMPV) is known to result in clinical manifestation similar to respiratory syncytial virus (RSV) in children. But some recent studies showed different features. This study compared the clinical manifestation of respiratory disease between hMPV and RSV. Methods: A total of 801 children who admitted to Seoul St. Mary’s Hospital for respiratory infection from January to June, 2012 were enrolled. Respiratory viral polymerase chain reaction (PCR) using nasopharyngeal swab was performed in all children. We grouped hMPV positive children and RSV positive children and compared clinical features between them by retrospective chart review. Results: Among 801 children, 365 showed one virus PCR positive with 44 showing hMPV and 41 showing RSV. Respiratory diseases were upper respiratory infection, acute bronchitis, acute bronchiolitis and pneumonia. The peak season was March and April for hMPV and February and March for RSV. Fever incidence, fever duration and neutrophil percent of complete blood cell count were higher in hMPV group than RSV group (P<0.05). The mean age of hMPV group was higher than RSV group (P<0.05). But in acute bronchiolitis children, there was no mean age difference between two group. Acute bronchiolitis incidence declined with increased age for both group (P<0.05). The hMPV group showed relatively lower bronchiolitis and higher pneumonia incidence than RSV group, suggesting relation with age. Conclusion: Respiratory infection by hMPV developed at late winter and spring, slightly later than RSV and at older age. The lower incidence of acute bronchiolitis for hMPV infection than RSV is maybe due to older age than RSV. (Allergy Asthma Respir Dis 2013;1:157-163)

Environmental policy implementation has been strengthened to protect the source waters in Korea and to improve their water quality. Increasing of non-point source caused water quality problem continuously. Research on runoff from forests, which occupy over 65% of the land in korea, is insufficient, and studies on the characteristics and influences of storm runoff are necessary. In this study, we chose to compare the effects of land use in the form of two types of forest distribution and then gathered data on storm characteristics and runoff properties during rainfall events in these areas. Furthermore, the significance and influences of the discharges were analyzed through correlation analysis, and multilateral runoff characteristics were examined by deducing a formula through COD(Mn) and TOC regression analysis. At two forest points, for which the basin areas differed from each other, flow changed according to storm quantity and intensity. The peak discharge at point A, where the basin area was big, was high, whereas water-quality fundamental items (BOD, COD(Mn), and SS) and TOC density were high at point B where the slope and storm intensity were high. Effects of dissolved organic matter were determined through correlation analysis, and the regression formulas for COD(Mn) and TOC were deduced by regression analysis. It is expected that the data from this study could be useful as basic information in establishing forest management measures.
