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.

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.

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.

자매예술이 된 음악과 회화 - ‘파라고네’ 논쟁의 재구성을 위한 단초들

정우진 ( Chung Woo Jin ) 한국미학회 2018 美學 Vol.84 No.4

‘비교’를 뜻하는 이탈리아어 ‘파라고네’(paragone)는 서양 미술사에서 한 문장으로 정의하기 어려울 정도로 다양한 의미를 지닌다. 때때로 특정한 경쟁관계, 주로 회화와 조각의 경쟁관계를 지칭하는 데 이 용어가 쓰이기는 하지만, 파라고네 전통의 핵심 텍스트인 레오나르도 다빈치의 『회화론』은 시문학과 음악을 포함할 정도로 그 범위가 훨씬 넓다. 르네상스 시대에 예술에 대한 고대의 논의를 수용하는 과정에서 크게 부각된 파라고네는 여러 예술의 비교(때로는 우열 논쟁)를 통해 진전된 이론적인 탐구의 일종이라고 보면 가장 좋을 것이다. 음악은 고대든 르네상스 시대든 파라고네 전통에서 중요한 역할을 해왔지만, 음악의 역할은 대체로 간과되어 온 것이 사실이다. 이 논문은 고대로 거슬러 올라갈 수 있는 여러 예술의 비교 전통에서 음악이 맡은 역할을 르네상스 시대의 사회적 맥락과 ‘모방’ 개념을 중심으로 한 미적인 차원 두 갈래로 조명하고, 이후 추상으로 넘어가는 문턱에서 하나의 이상으로서 여러 예술의 가치를 판가름하는 시금석이 될 음악을 회화의 새로운 파라고네로 제시하기 위한 예비 작업을 수행한다. 이로써 ‘자매예술’로서 음악과 회화가 논의될 수 있는 이론적인 기반을 마련하고 이들을 둘러싼 파라고 네 논쟁의 미학적 의의를 모색하는 것이 이 논문의 목적이다. The Italian noun paragone, meaning literally comparison, has had various significations when it has been used in Western art history. While it sometimes had referred to the specific rival relationship of painting and sculpture, Leonardo’s Trattao della pittura, the core text in the paragone tradition, extends its scope much wider to engage both poetry and music. It might be well to think of the paragone as a kind of theoretical scrutiny proceeding through comparisons of various arts, which loomed large in the course of reception of the ancient discussion on the arts from the period of Renaissance. Music have played a critical part in this paragone tradition, in both ancient and Renaissance periods, but it is true that its role has been to a great extent ignored in modern scholarship. The present essay sheds light on the role of music in the tradition of the comparison of arts in terms of both the social context in the Renaissance period and the aesthetic level focused on the notion of representation(mimesis). And it tries to carry out the preliminary tasks to present music as a new paragone for painting in the nineteenth century which become the touchstone for the value and authenticity of the visual arts behind the birth of abstraction. This essay is an attempt to provide the theoretical basis for the discussion of music and painting as sister arts; and to search for some aesthetic significance of the paragone dispute revolving around them.
