Degrees of Air Pollutio in Daejeon Area was determined by measuring the quantity of sulfur oxides and dust-fall from January to December, 1972. 1) The mean value of sulfur oxides and dust-fall in the whole area of the city were 0.51mg SO₃/day/100㎠ Pbo₂ and 27.87 ton/㎢/month. respectiuely, showing the lower degree of pollution than the other large cities such as Seoul, Busan, and Daegu. 2) The mean values of sulfur oxides and dust-fall were highest in the north-east area of the city (0.58mgSO₃/day/100㎠ Pbo₂and 32.35ton/㎢/month), while lowest in the south-west area (0.41mg SO₃/day/100㎠Pbo₂.and 23.10 ton/㎢/month). 3) They were highest in the 1 to 2 kilometer zone from the center of the city(0.56mgSO₃/day/100㎠ Pbo₂ and 33.95 ton/㎢/month) and lowest in the 2 to 3 kilometer zone(0.45mg SO₃/day/100㎠PbO₂ and 22.87 ton/㎢/month). 4) Sulfar oxides contents were lowest in August (0.14mg SO₃/day/100㎠ PbO₂), but showd no great variations throughout the other months. 5) Quantity of dust-fall ahowed the highest value in April, decreasing to the lowest value till August.

로이스터(Royster) 담론에 내재된 한국 야구의 옥시덴탈리즘(Occidentalism)

박보현 한국스포츠사회학회 2013 한국스포츠사회학회지 Vol.26 No.1

This study aims to find out the way Korean baseball describes and defines Major League Baseball (MLB) through Jerry Royster who came from MLB to take on the head coaching job at Lotte Giants team for 3 years from 2008 to 2010. For this purpose, this research conducts discourse analysis on Jerry Royster represented in Korean media. News articles about Jerry Royster from November 2007 to December 2011 searched via Media Daum are analyzed as data. From the first search, 16,600 news articles are collected, 424 of which are finally used for discourse analysis. As a result, this study discovers that both positive and negative Occidentalism exist in Korean baseball. Positive Occidentalism represented in Royster discourse is ‘MLB is more developed baseball’, ‘MLB style baseball is more enjoyable’ and ‘western leadership is more rational and reformative’. In contrast, negative Occidentalism in Royster discourse is ‘MLB style baseball is not strong at short-term series’, ‘You can never win league title with MLB style baseball’. This seems closely related to the knowledge-power saying that Korean baseball no more needs to learn from MLB, which is a main discourse as well used by Korean coaches who tries to justify the exclusion of foreign coaches from Korean baseball. 본 연구는 2008년부터 2010년까지 3년 동안 롯데자이언츠를 이끌었던 메이저리그 출신 제리 로이스터(Jerry Royster)감독을 통해 한국야구가 메이저리그를 묘사하고 규정하는 방식, 즉 옥시덴탈리즘(Occidentalism)을 규명하고자 하였다. 이를 위해 한국 미디어가 그려낸 ‘로이스터 야구’의 담론을 분석하였다. 2007년 11월부터 2011년 12월 30일까지 미디어 다음으로 검색된 로이스터 감독과 관련된 뉴스기사가 자료로 활용되었다. 1차 검색된 뉴스기사 16,600건 중 424건을 최종 분석에 활용하였다. 분석 결과, 메이저리그에 대한 한국야구의 옥시덴탈리즘은 긍정적 옥시덴탈리즘과 부정적 옥시덴탈리즘이 공존하는 것으로 드러났다. 먼저 로이스터 담론에 나타난 긍정적 옥시덴탈리즘은 ‘메이저리그=선진야구’, ‘메이저리그=재미있는 야구’, ‘서구의 리더십=합리적, 개혁적’이라는 이미지였다. 반대로, 부정적 옥시덴탈리즘은 로이스터 야구에 대한 ‘오해’와 ‘오역’, 그리고 ‘왜곡’에 기반해 ‘메이저리그=단기전에 약한 야구’, ‘메이저리그=우승할 수 없는 야구’ 로 묘사하고 있었다. 이는 또한 국내 지도자들의 외국 지도자에 대한 배타성을 정당화하는 담론 즉, 메이저리그는 더 이상 한국 야구가 동경할 대상이 아니라는 지식-권력과 밀접한 관련을 맺고 있는 것으로 나타났다.

Analysis of pairings of colors and materials of furnishings in interior design with a data-driven framework

박보현,Hyun Kyung Hoon 한국CDE학회 2022 Journal of computational design and engineering Vol.9 No.6

Color–material furnishing pairing is known as a “black-box” for interior designers. The overall atmosphere of a space can be changed by modifying furnishing combinations, e.g., to express modern or classic styles. Designers carefully choose pairings of colors and materials that fit their intended interior design styles based on experience and knowledge. However, no specific principles or rules have yet been established. Therefore, this study aims to derive a furnishing pairing principle based on a novel framework comprising object detection, color extraction, material recognition, and network analysis. We used the proposed framework to analyze large-scale interior design image data (N =  24194) collected from an online interior design platform. We also used the authenticity algorithm to analyze the relative influence of styles. By using the data-driven method from large-scale data in each of the eight interior styles, we derived authentic color, material, and furnishing combinations. Our study results revealed that images with high authenticity values in each style matched existing style descriptions. Additionally, the proposed framework allows interior style image retrieval based on a specific color, material, and furnishing combination. Our findings have implications for research on the development of style-aware furniture retrieval systems and automatic interior design generation methods.

The unconfined compressive strength of lightweight treated soils strongly depends on mixing ratio. To characterize the relation between various LTS components and the unconfined compressive strength of LTS, extensive studies have been conducted, proposing normalized factor using regression models based on their experimental results. However, these results obtained from laboratory experiments do not expect consistent prediction accuracy due to complicated relation between materials and mix proportions. In this study, deep neural network model(Deep-LTS), which was based on experimental test results performed on various mixing conditions, was applied to predict the unconfined compressive strength. It was found that the unconfined compressive strength LTS at a given mixing ratio could be resonable estimated using proposed Deep-LTS. 경량혼합토의 일축압축강도는 배합비에 크게 의존한다. 경량혼합토와 다양한 경량혼합토의 구성성분들의 관계를 특징짓기 위한 기존연구에서는 시험을 통한 회귀모델을 사용하여 정규화계수를 제안하였다. 그러나 실내시험에서 얻은 결과는 재료와 배합비사이의 관계가 복잡하기 때문에 일정한 예측의 정확도를 기대할 수 없다. 이 연구에서는 다양한 배합조건에서 수행된 실내시험결과를 바탕으로 심층신경망 모델을 적용함으로써 경량혼합토의 일축압축강도를 예측하였다. 제안된 심층신경망 모델을 사용함으로써 설계 배합조건으로 구성된 경량혼합토의 일축압축강도 값을 합리적으로 산정할 수 있다.

Objectives: The purpose of the study was to examine the cost of illness and quality of life (QOL) of patients and caregivers with mild cognitive impairment (MCI) or Alzheimer’s disease (AD) based on their severity and to identify factors affecting the QOL of the patients and their caregivers. Methods: The subjects of this study were 140 patients with MCI or AD and 121 caregivers for those patients. The cost of illness was investigated as direct costs (medical and nonmedical costs) and indirect costs (productivity loss). The medical costs was calculated using medical expense data received from hospitals, and nonmedical costs and productivity loss were calculated using data collected in a mail survey. Patients’ QOL was measured with the Korean versions of EuroQol-5D (KEQ-5D) and KQOL-AD, while caregivers’ QOL was measured with KEQ-5D and the Korean version of Carer Quality of Life. Results: Average annual direct costs were measured as follows: MCI or very mild AD−2470000 won; mild AD−13663000 won; moderate AD−14292000 won; and severe AD−16591000 won. Indirect costs were measured in terms of average lifetime productivity loss as follows: MCI or very mild AD−6117000 won; mild AD−6336000 won; moderate AD−20871000 won; and severe AD−19773000 won. Patients’ QOL showed a statistically significant decline as condition severity increased, whereas caregivers’ QOL showed a significant decline between MCI or very mild AD and mild AD groups. Different factors affected the QOL of patients and their caregivers: informal medical costs and long-term care costs affected patients’ QOL, and informal care costs affected caregivers’ QOL. Conclusion: The greatest increase in average annual costs was observed between MCI or very mild AD and mild AD, and caregivers’ QOL deterioration was observed between MCI or very mild AD and mid AD. To curb rising costs and avoid deterioration of patients’ and caregivers’ QOL, medical and social interventions are required to prevent the progression from MCI or very mild AD to mild AD.

Purpose: To investigate the incidence and clinical course of acute endophthalmitis after idiopathic epiretinal membrane (iERM) surgery employing microincision vitrectomy (MIVS). Methods: We retrospectively reviewed the medical records of eyes with acute endophthalmitis developing after iERM surgery via 23- or 25-gauge MIVS from 2011 to 2021. The incidence, culture-positive rate (and responsible bacteria), final visual acuity (VA), and factors affecting poor visual outcomes were assessed. Results: Acute endophthalmitis developed in 20 of the 12,921 eyes (0.15%) after MIVS. Of these, 14 of 3,180 eyes treated via iERM (0.44%, one per 227 procedures) developed endophthalmitis; the incidence ratio (iERM versus non-iERM) was 7.1 (p < 0.001, 95% confidence interval [CI] = 2.6-22.7). At least one sclerotomy remained unsutured in all eyes after iERM surgery. Thirteen eyes (92.9%) were given intravitreal antibiotic injections after emergency vitrectomy, and one eye was treated with intravitreal antibiotic injection alone. Staphylococcus epidermidis was cultured from four eyes (28.6%); three strains were methicillin- resistant. All final VAs were not better than the initial VAs; the average VA decreased from 20/42 to 20/259 (p < 0.001). Six eyes (42.9%) attained legal blindness status (final VA < 20/200); Macular invasion was a unique risk factor for such blindness (p = 0.020, odds ratio = 35.0, 95% CI = 1.7-703.0). Conclusions: Acute endophthalmitis developing after iERM surgery with MIVS was more common than such endophthalmitis after other retinal surgery. Approximately 40% of the former patients became legally blind, and the risk was higher in eyes with macular involvement of endophthalmitis. 목적: 미세절개유리체절제술로 특발 망막앞막 수술 후 발생한 급성 안내염의 발생률과 임상 경과를 알아보고자 하였다. 대상과 방법: 2011년부터 2021년까지 미세절개유리체절제술로 특발 망막앞막 수술 후 급성 안내염이 발병한 증례들의 의무기록을 분석하였다. 안내염의 발생률, 배양 양성 비율 및 균주, 최종 시력에 대해 조사 후 불량한 시력 예후에 영향을 주는 인자들을 조사하였다. 결과: 총 12,921안에서 미세절개유리체절제술 후 20안(0.15%)에서 급성 안내염이 발생하였다. 그중 3,180안의 특발 망막앞막 증례들에서 14안의 안내염이 발생하여 발생률과 발생률비는 각각 0.44% 및 7.1이었다(p<0.001, 95% confidence interval [CI]=2.6-22.7). 14안모두 특발 망막앞막 수술 시 하나 이상의 공막창을 봉합하지 않았다. 안내염 진단 후 13안은 응급 유리체절제술 후 유리체내 항생제주사를 시행하였고 1안은 유리체내 항생제 주사만으로 치료되었다. 배양 결과 4안(28.6%)에서 모두 표피포도구균이 배양되었고 3안은 메티실린 내성이었다. 최종 시력은 모든 증례들에서 첫 수술 전 시력보다 호전되지 않았고, 그 평균은 20/42에서 20/259로 감소하였다(p<0.001). 법적 실명에 해당하는 20/200 이하의 최종 시력은 6안(42.9%)으로 안내염의 황반 침범은 실명 위험이 높은 단일 소견이었다(p=0.020, odds ratio=35.0, 95% CI=1.7-703.0). 결론: 미세절개유리체절제술을 통한 특발 망막앞막 수술 후 급성 안내염은 다른 망막질환의 수술 후 급성 안내염보다 높은 빈도로발생한다. 해당 안내염이 발병하면 약 40%에서 법적 실명을 할 수 있고 안내염의 황반 침범 시 그 위험이 증가한다.
