        This study investigated the age dependencies in ambient air pollution-associated asthma hospitalization from 2003 to 2005 in Seoul. For all ages and the age groups of 0-14, 15-64, and 65+years, the Generalized Additive Model (GAM) was used to estimate the relative risks of daily asthma hospitalization associated with changes in particulate matter and ozone. The time-trends, seasonal variances, day effects, temperature, humidity, and pressure at sea level were controlled in the models. Significant associations were observed between asthma hospitalization and the levels of $PM_{10}$ and $O_3$. The relative risks (RRs) of asthma hospitalization for every 10 unit increases in $PM_{10}({\mu}g/m^3)$ and $O_3$(ppb) were 1.008 (95% CI 1.005-1.012), and 1.012 (95% CI 1.003-1.020), respectively. Evaluated over $10\;{\mu}g/m^3$ increase in $PM_{10}$, we found the relative risks of asthma hospitalization to be 1.009 (95% CI 1.004-1.014) in 0-14 age group, and 1.015 (95% CI 1.008-1.022) in 65+ age group. Considering 10 ppb increase in $O_3$, those were 1.014 (95% CI 1.003-1.024) in 0-14 age group, and 1.025 (95% CI 1.009-1.041) in 65+ age group. It was concluded that current levels of ambient air pollution in Seoul make a significant contribution to the variation in daily asthma hospitalization. Further reduction in air pollution is necessary to protect the health of the community, especially that of the higher risky groups including children and elderly population.

        방송콘텐츠 분석을 통한 한국 버라이어티 프로그램의 브랜드 아이덴티티(BI)에 대한 담론 -MBC 버라이어티 프로그램 <무한도전>을 중심으로-

        배현주 동서대학교 일본연구센터 2010 次世代 人文社會硏究 Vol.6 No.-

        Korean broadcasting contents market`s main contents is drama. By the way, Recently, variety program is noted newly in broadcasting contents market. Because various age group can watch together variety program, it Has a wide consumption market, and advantage that production cost is inexpensive than drama. Variety program of these day taking a serious view reality, and have pastime and sensitivity. To variety program receives interest to viewers continuously like now, brand identity should be constructed. Because program that brand identity is constructed can have clout socially and extend life for a long time. To variety program constructs brand identity, variety program must develop unique format continually, and construct inseverable communication with viewers. And first of all, have included really inside program and must be able to have guided sympathy from people.

        This study was performed to delineate the removal phenol in solutions using of ozone, ozone/$H_2O_2$ and ozone/GAC. The disinfection by-product of phenol by ozonation, hydroquinone, was analyzed and it s control process was investigated. The followings are the conclusions that were derived from this study. 1. The removal efficiency of phenol by ozonation was 58.37%, 48.34%, 42.15%, and 35.41% which the initial concentration of phenol was 5 mg/l, 10 mg/l, 15 mg/l, and 20 mg/l, respectively. 2. The removal efficiency of phenol by ozonation was 42.95% at pH 4.0 and 69.39% at pH 10, respectively. The removal efficiencies were gradually increased, as pH values were increased. 3. With the ozone/$H_2O_2$ combined system, the removal efficiency of phenol was 72.87%. It showed a more complete degradation of phenol with ozone/$H_2O_2$ compared with ozone alone. 4. When ozonation was followed by filtration on GAC, phenol was completely removed. 5. Oxidation, if carried to completion, truly destroys the organic compounds, converting them to carbon dioxide. Unless reaction completely processed, disinfection by-products would be produced. To remove them, ozone/GAC treatment was used. The results showed that disinfection by-product of phenol by ozonation, hydroquinone, was completely removed. These results suggested that ozone/GAC should also be an appropriate way to remove phenol and its by-product.

      • 초미세먼지로 인한 어린이 환경성 질환 영향 연구

        배현주,임유라,간순영,이종태 한국환경정책평가연구원 2014 수시연구보고서 Vol.2014 No.9

        본 연구에서는 서울시를 대상으로 초미세먼지(PM<sub>2.5</sub>)와 어린이 천식 입원에 대하여 시공간적 분포를 탐색하고, 초미세먼지(PM<sub>2.5</sub>)로 인한 어린이 천식 입원 영향을 정량적으로 평가하여 초미세먼지(PM<sub>2.5</sub>)의 농도 개선에 따른 건강피해 감소의 건강편익을 산출하였다. 2007년부터 2013년까지 서울시를 대상으로 초미세먼지(PM<sub>2.5</sub>)와 어린이 천식 입원에 대하여 시간적 공간적 분포를 살펴보았다. 크리깅 분석결과 초미세먼지(PM<sub>2.5</sub>) 농도는 2010년부터 2103년까지 지속적으로 감소하는 추세를 보였으며, 계절별로는 봄과 겨울이 여름과 가을과 비교하여 농도가 높게 나타났다. 15세 미만 연령집단의 천식 입원이 집중적으로 발생하는 지역을 탐색한 결과, 2011년과 2012년을 제외하고는 서울 서북부에 속한 지역이 대부분 고위험지역(hot-spot)에 속하는 것으로 나타났다. 초미세먼지(PM<sub>2.5</sub>)와 15세 미만 연령 천식 입원의 공간적 상관성을 분석하기 위해 Rapid inquiry facility(RIF)를 활용하여 위험분석을 실시한 결과 초미세먼지(PM<sub>2.5</sub>)농도가 낮은 구간보다 높은 구간에서 천식 입원환자 발생이 높게 나타났다. 또한 2007년부터 2013년까지 서울시를 대상으로 초미세먼지(PM<sub>2.5</sub>)와 천식 입원영향을 정량적으로 평가하였다. 건강영향 평가 결과 초미세먼지(PM<sub>2.5</sub>)의 농도 증가는 어린이 천식 입원 발생위험을 통계적으로 유의하게 높이고 있었다. 연령별로는 어린이 중에서 상대적으로 더욱 민감집단인 0~4세 연령집단이 15세 미만 연령집단보다 초미세먼지(PM<sub>2.5</sub>)로 인한 천식 입원 발생위험이 높았으며, 성별에 따라서는 여아보다 남아가 초미세먼지(PM<sub>2.5</sub>)의 영향을 더 많이 받는 것으로 나타났다. 서울시의 2013년 초미세먼지(PM<sub>2.5</sub>)의 농도 수준이 WHO에서 권고하는 대기질 기준을 달성한다고 가정하였을 때, 본 연구에서 도출한 대기오염 농도 증가에 따른 천식 입원의 농도-반응(concentration-response)함수를 적용하여 초미세먼지(PM<sub>2.5</sub>)의 농도 개선으로 기대되는 천식 입원 감소의 건강편익을 산출하였다. 본 연구결과 국민의 건강보호를 위하여 2015년 시행 예정인 초미세먼지(PM<sub>2.5</sub>)에 대한 대기환경기준의 단계적 강화가 필요하며, 환경정책의 건강편익 산정결과를 토대로 정책의 우선순위와 우선대상지역을 결정하는데 유용한 판단 근거로 활용할 수 있다. This study examined spatial and temporal distribution on PM2.5 and children's asthma admission in Seoul, qualitatively evaluated the effects of PM2.5 on children's asthma admission, and estimated the health benefit of health damage reduction, according to PM2.5 concentration improvement. This study examined the spatial and temporal distribution of PM2.5 and children's asthma hospital admission in Seoul from 2007 to 2013. As a result of krigging analysis, the concentration of PM2.5 showed a constantly declining trend from 2010 to 2013, and the concentration was higher in spring and winter, compared to summer and autumn. According to search for the areas, where asthma admission of the age group of 15 and younger children occurred intensively, most northwestern area of Seoul was the hot-spot. For spatial correlation analysis between PM<sub>2.5</sub> and the asthma admission of children aged 15 and younger, this study conducted a risk analysis using rapid inquiry facility(RIF). As a result, the relative risk of asthma admission was higher in the area with higher PM<sub>2.5</sub> concentration than in the area with lower PM2.5 concentration. This study also quantitatively evaluated PM<sub>2.5</sub> and its effects on asthma admission in Seoul from 2007 to 2013. As a result of health effect evaluation, PM<sub>2.5</sub> increase significantly raised children's asthma admission. By age, the age group aged 0 to 4 had relatively higher risk of asthma hospital admission due to PM<sub>2.5</sub> than that of the age group aged 15 and younger. By gender, boys were affected more by PM<sub>2.5</sub> than girls. If Seoul's PM<sub>2.5</sub> concentration in 2013 is assumed to meet the air quality criterion recommended by WHO, this study estimated the health benefit of the decrease in asthma admission through PM<sub>2.5</sub> concentration improvement by applying a concentration-response function of asthma admission drawn by this study, according to air pollution concentration increase. According the findings of this study, the step-by-step consolidation of air environment criteria of PM<sub>2.5</sub>, which is scheduled to be executed in 2015, is required for people's health protection. Also, the health benefit estimation results of environmental policy can be used as useful judgement basis in deciding policy priority and preferential areas.

Purpose: We studied the direction and distribution pattern of slope of a fixation disparity curve(FDC) after measuring fixation disparity and associated phoria at near distance and searched three results variable giving an effect on FDC. This study is expected to apply diagnose and prescription of binocular abnormality. Methods: We measured the dissociated phoria and the fixation disparity for 85 subjects at near distance. All subjects had a monocular best-corrected visual acuity of 18/20 or better, had no strabismus as determined by cover test, had no vertical phoria by the Maddox rod method, and had no ocular history. The dissociated phoria measured Modified Thorington Method and fixation disparity measured with Wesson fixation disparity card at near distance. Results: The percentage distribution of types fixation disparity curves was that prevalence of Type I (69.4%) was the highest, followed by Type III (15.3%), Type IV (9.4%), Type II (5.9%) at near distance. The fixation disparity at near distance was most effect on associated phoria and slope of fixation disparity.(p=0.000). Conclusion: The fixation disparity at near distance is valuable parameter in the diagnosis and prescription of binocular vision disorder.
