청정연료와 저유황유의 공급확대에 따른 대구지역의 대기오염 개선효과를 분석하기 위하여 향후 1996, 2001년 대구지역의 유종별, 소비부문별 소비량을 추정하고 이에 따른 아황산가스, 분진, 질소산화물 및 일산화탄소에 대한 배출량을 각각 산정하였다. 특히 향후 대구지역 대기중 아황산가스농도에 대하여 개정된 환경기준치의 달성가능성 여부를 연간 총배출량측면에서 검토한 결과 2001년의 아황산가스 배출량이 추정된 허용배출량 이하로 떨어질 것으로 나타나 저황유의 공급과 청정연료 사용의무화정책을 현재 계획대로 추진할 경우 아황산가스 농도는 대체로 환경기준을 충분히 달성할 수 있을 것으로 판단되었다. A study was carried out to evaluate the improvement of air quality in Taegu area in the years of 1996 and 2001 with the extended supply of cleaner fuels such as town gas and low sulfur fuel oil. The emission quantities of the air pollutants from the combustion of various fuel were estimated with respect to the sections of end-use in this area. With the implementation of the planned fuel policy to this area, the level of sulfur dioxide in the ambient air will satisfy the revised ambient air quality standard based on the yearly total quantity of the sulfur dioxide emission. If the fuel policy is implemented as scheduled, the attainability of the ambient air quality standard of sulfur dioxide will be possible as the total quantity of sulfur dioxide emission will be well below of that of the predicted value obtained under current fuel policy.

Food allergen sensitization in young children with typical signs and symptoms of immediate-type food allergies: a comparison between monosensitized and polysensitized children

Kim, Na Yeon,Kim, Ga Ram,Kim, Joon Hwan,Baek, Ji Hyeon,Yoon, Jung Won,Jee, Hye Mi,Baek, Hye Sung,Jung, Yong Ho,Choi, Sun Hee,Kim, Ki Eun,Shin, Youn Ho,Yum, Hye Yung,Han, Man Yong,Kim, Kyu-Earn The Korean Pediatric Society 2015 Clinical and Experimental Pediatrics (CEP) Vol.58 No.9

Purpose: The clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies. Methods: The study included children <10 years of age with signs and symptoms indicative of immediate-type food allergies. Serum total IgE level was measured, and ImmunoCAP analysis for food allergens was performed. Results: The mean age of the study subjects was $1.6{\pm}1.6$ years (75 boys and 51 girls). Thirty-eight children (30.2%) were monosensitized and 88 children (69.8%) were polysensitized. Multivariate logistic regression analysis showed that the development of polysensitization to common food allergens was positively associated with a parental history of allergic rhinitis (adjusted odds ratio [aOR], 6.28; 95% confidence interval [CI], 1.78-22.13; P=0.004), season of birth (summer/fall) (aOR, 3.10; 95% CI, 1.10-8.79; P=0.033), and exclusive breastfeeding in the first 6 months of age (aOR, 3.51; 95% CI, 1.20-10.25; P=0.022). Conclusion: We found significant clinical differences between children with monosensitization and those with polysensitization to common food allergens and identified risk factors for the development of polysensitization in young children with immediate-type food allergies. Clinicians should consider these clinical risk factors when evaluating, counseling, treating, and monitoring young children with food allergies.

「오감도 시 제1호」와 이상(李箱)이라는 페르소나의 이중성 식민지 근대 시공간의 다차원적 조감도로서 이상 시 읽기

김백영 ( Kim Baek-yung ) 민족문학사학회·민족문학사연구소 2018 민족문학사연구 Vol.67 No.-

李箱 시의 다의성은 어디에서 비롯되는가? 본 연구에서는 그 원인이 이상이라는 문학적 페르소나에 내재된 양면성에서 비롯된 것으로 보고, 그 형성 국면의 작품인 「오감도 시 제1호」에 초점을 맞춰 다음과 같은 두 가지 질문을 통해 이상의 삶과 작품 세계에 대한 새로운 해석 틀을 벼려내고자 했다. 첫 번째 질문은 건축기술자이자 일문 시 작가인 김해경과 조선문단에 혜성과 같이 나타난 신예 작가 이상의 관계를 어떻게 설정할 것인가의 문제이다. 연작시 「오감도」는 자연인 김해경으로부터 독립된 새로운 문학적 페르소나인 이상을 확립한 작품으로 자리매김할 수 있다. 두번째 질문은 김해경의 ‘조감도’와 이상의 ‘오감도’의 관계를 해명하는 문제로, ‘조감’ 개념에 대한 분석을 통해 그의 작품에 다음 두 가지 모티브가 모순적으로 공존하고 있음을 발견할 수 있었다. 하나는 유년기 이래 그의 삶을 품어온 생활세계가 식민화되는 과정에 대한 피식민자로서의 원초적 공포감과 불안의식이고, 다른 하나는 근대문명의 하이모더니즘적 기획의 허구성에 대한 초국적·전위적 지식인의 급진적 비판의식과 초월의지이다. 초기 작품에서부터 김해경은 근대권력의 투시적 시선이 지닌 특권성과 폭력성에 대해 예리한 비판의식을 드러냈으며, 근대 시공간 질서의 보편적 구조를 꿰뚫어보고 있었다. 연작시 「조감도」와 「오감도」에는 상대성 이론 등 그가 흡수한 근대 과학혁명의 지적 발견, 총독부 소속 건축기사로서의 직업적 경험과 피식민 조선인으로서의 이중의식, 그리고 다다이즘 등 당대 초국적 아방가르드 예술가들의 사상적 영향이 녹아들어 있다. 그는 근대 기계문명의 시공간이 어떤 인식론적 혁명 위에 축조되어 있는지 예리하고 명증하게 간취하고 있었으며, 더 나아가 그것이 초래한 인간성의 내면의 심층적 변화까지도 투시하여 보여주고자 했다. 때문에 근대사회에 대한 그의 조감하는 시선에는 단지 물리적 공간에 대한 투시를 넘어서 내면적 인간성과 사회구조적 문제의 복합적 상관성에 대한 성찰이 포함된다. 「오감도 시 제1호」는 이상이 조선 문단에 자신의 존재를 알린 첫 작품이다. 김해경은 이를 계기로 이상이라는 새로운 페르소나를 확립함으로써 자신의 불우한 귀속지위에 얽혀있는 존재론적 굴레로부터 벗어나 초국적 다다이즘과 시공간적 비월(飛越)의 꿈을 이루고자 했다. 이상의 문학적 실천에서 나타나는 모호성과 다의성은 근대적 시공간에 대한 인식론적 각성과 존재론적 해방 사이의 극복 불가능한 절대적 간극 위에 형성된 이상이라는 페르소나의 본래적 이중성의 소산으로 볼 수 있다. Where does the polysemy of Yi Sang‘s poetical works stem from? It is difficult to grasp full meanings of his poem by regarding him simply as an owner of a fallen and diseased body, a patient with severe schizophrenia, a weak colonial intellectual or a modernist street observer. Focusing on the 「Crow’s-Eye Views No. 1」 and examining following two questions, this article aims to bring out an alternative framework to interpret Yi Sang’s poems. Firstly, why Kim Hae-kyung created his new pseudonym named Yi Sang and what are the critical characteristics of this new literary persona? Secondly, why Kim Hae-kyung and Yi Sang titled their major work by using the terminology of ‘jogam/ogam’ which meaned ‘bird’s eye views/crow’s eye views’? By answering these two questions, I tried to disclose the main reasons of both the ambilaterality of the persona of Yi Sang and the polysemy of his poetical works. From the outset of his literary career, Yi Sang has had a brilliant vision to penetrate the universal structure of modern spatio-temporal order, realizing both the privilege and the violence of the modern power of seeing. Yi Sang’s literary expressions of his bird’s eye view of modern society has caught the multi-dimensional changes including not only the materialistic and socio-structural changes but also the changes of deep inner humanity. By writing and publishing 「Crow’s-Eye Views No. 1」, he tried to establish a new persona to escape his heavy ontological bindings entangled in Kim Hye-kyung’s disturbed backgrounds. Through his ingenious radical practices of literary dadaism, he tried to realize the idealistic dream of artistic liberation and/or to transcend the limitations of the spatio- temporal conditions of the colonial modern society. Yi Sang’s frustrated literary practice can be regarded as an inevitable result of the impossible transcendental efforts to overcome the absolute gap between one’s epistemological awakening and ontological liberation of the colonial modern reality.

Background Viral hemorrhagic septicemia (VHS) is a serious viral disease that infects the olive flounder in South Korea. The Korean aquaculture industry experienced an economic loss caused by the high infectivity and mortality. Objective This study aimed to evaluate the infection density of VHSV in various organs of the olive flounder including spleen, liver, kidney, stomach, esophagus, intestine, gill, muscle, heart, and brain. Olive flounders were collected from a local fish farm and injected subcutaneously with 106 PFU/fish. Methods Each 15 fish were sampled at 0, 3, and 7 days post challenge (dpc), respectively, to perform quantitative analysis of VHSV using SYBR-green based real-time PCR in various tissues including spleen, liver, head-kidney, body-kidney, muscle, esophagus, stomach, intestine, gill, and brain. Results Organs infected with VHSV were obtained after 3 and 7 days. Each organs were examined for viral infection using real-time PCR. The data obtained from this experiment revealed copy numbers higher than 10 copies per 100 ng cDNA in the spleen (15.26 ± 3.11 copies/100 ng of cDNA), muscle (11.24 ± 2.25 copies), and gill (14.23 ± 6.26 copies), but lower in liver, head-kidney, body-kidney, esophagus, brain and stomach. Conclusion The present study, together with previous data, demonstrated that the gill, spleen, and muscle are the major target organs of VHSV in olive flounder. Therefore, central monitoring of spleen, gill and muscle should be considered and might be necessary if anti-VHSV treatment is to be successful in infected olive flounder.

Loquat (Eriobotrya japonica) extracts suppress the adhesion, migration and invasion of human breast cancer cell line

Kim, Min-Sook,You, Mi-Kyoung,Rhuy, Dong-Young,Kim, Yung-Jae,Baek, Hum-Young,Kim, Hyeon-A The Korean Nutrition Society 2009 Nutrition Research and Practice Vol.2 No.3

We examined the inhibitory effects of loquat methanol extract on the adhesion, migration, invasion and matrix metalloproteinase (MMP) activities of MDA-MB-231 human breast cancer cell line. Cells were cultured with DMSO or with 10, 25, or 50 ${\mu}g/ml$ of loquat methanol extract. Both leaf and seed extracts significantly inhibited growth of MDA-MB-231 cells in a dose-dependent manner, although leaf extract was more effective. Adhesion and migration were significantly inhibited by loquat extracts in a dose-dependent manner. Loquat extract also inhibited the invasion of breast cancer cells in a dose-dependent manner and leaf extract was more effective than seed extract. MMP-2 and MMP-9 activities were also inhibited by loquat extract. Our results indicate that methanol extracts of loquat inhibit the adhesion, migration and invasion of human breast cancer cells partially through the inhibition of MMP activity and leaf extract has more anti-metastatic effects in cell based assay than seed extract. Clinical application of loquat extract as a potent chemopreventive agent may be helpful in limiting breast cancer invasion and metastasis.

Fluorine Functionalized Graphene Nano Platelets for Highly Stable Inverted Perovskite Solar Cells

Kim, Gi-Hwan,Jang, Hyungsu,Yoon, Yung Jin,Jeong, Jaeki,Park, Song Yi,Walker, Bright,Jeon, In-Yup,Jo, Yimhyun,Yoon, Hyun,Kim, Minjin,Baek, Jong-Beom,Kim, Dong Suk,Kim, Jin Young American Chemical Society 2017 NANO LETTERS Vol.17 No.10

<P>Edged-selectively fluorine (F) functionalized graphene nanoplatelets (EFGnPs-F) with a p-i-n structure of perovskite solar cells achieved 82% stability relative to initial performance over 30 days of air exposure without encapsulation. The enhanced stability stems from F substitution on EFGnPs; fluorocarbons such as polytetrafluoroethylene are well-known for their superhydrophobic properties and being impervious to chemical degradation. These hydrophobic moieties tightly protect perovskite layers from air degradation. To directly compare the effect of similar hydrophilic graphene layers, edge-selectively hydrogen functionalized graphene nanoplatelet (EFGnPs-H) treated devices were tested under the same conditions. Like the pristine MAPbI(3) perovskite devices, EFGnPs-H treated devices were completely degraded after 10 days. The hydrophobic properties of EFGnPs-F were characterized by contact angle measurement. The test results showed great water repellency compared to pristine perovskite films or EFGnPs-H coated films. This resulted in highly air-stable p-i-n perovskite solar cells.</P>

강남 개발과 올림픽 효과

김백영(Kim, Baek Yung) 도시사학회 2017 도시연구 Vol.- No.17

이 글에서는 스포츠 메가이벤트가 도시공간에 미친 영향, 올림픽이 지닌 ‘도시개발의 촉매제’로서의 특성에 주목하여 1988 서울올림픽이 강남 개발과 서울의 도시발전에 미친 영향에 대해 살펴보았다. 올림픽을 개최할 수 있는 국제 규모의 경기장과 선진 대도시 수준의 세계도시를 건설하려는 계획은 잠실지구 개발사업이 본격화된 1970년대초부터 등장했다. 유신정권의 강력한 정책적 의지에 힘입어 서울시는 1970년대초부터 영동・잠실지구 신시가지를 포함하는 다핵화된 성상도시 플랜을 수립하고 잠실지구를 국제적 스포츠경기 유치를 위해 특화된 올림픽타운으로 조성하려는 계획을 수립했다. 1974년 잠실지구가 종래의 토지구획정리사업을 통해 조성된 단순한 주거타운과는 차별화된, ‘도시다움의 추구’라는 미래 이상도시 건설을 염두에 둔 종합적 플랜의 대상으로 재설정된 것은 이러한 배경에서다. 88서울올림픽 유치가 결정되자, 1980년대 서울시는 신군부 정권 주도하에 ‘세계는 서울로, 서울은 세계로’라는 표어에 부응하는 ‘국제도시’이자 ‘선진도시’로서 단기간에 압축적이고도 전 방위적으로 그 면모를 일신해 나아갔다. 한강고수부지 개발과 강남 · 북을 잇는 교량 건설, 동서 방향의 도시고속화도로와 지하철 건설 등 한강개발과 교통망 정비사업이 그 한 축을 담당했다면, 서울다핵도시화 계획에 따른 잠실 올림픽타운의 미관지구 조성과 도시 전반의 공원화 사업 등 도시미화운동은 그 다른 한 축에 해당한다. 결과적으로 1960~70년대 박정희 정권의 국가주의적 계획에서 비롯되어 ‘86 · 88의 시대’를 거치면서 관 주도적으로 추진된 올림픽도시 만들기 프로젝트는 강남 신시가지가 경이적인 규모와 속도와 획일성으로 조성되게끔 한 강력한 촉매제로 작용했다고 볼 수 있다. 그 과정에서 초대형 아파트단지 집중지역으로 재탄생한 강남은 한국 중산층 주거의 새로운 모델이자 ‘강남화’ 현상의 근거지가 되었다. Considering Olympics as a catalyst for urban development, this article examined the effects of the 1988 Seoul Olympic Games on the development of Gangnam area in Seoul. The plan to construct an international stadium and an advanced metropolitan city that can host the Olympics has been in place since the early 1970s, when the Jamsil district development project has started in earnest. Thanks to the strong political will of the Yushin regime, the city of Seoul established a plan to construct a star-shaped multi-core city plan, including new city areas of Yeongdong and Jamsil districts, as new cores in the early 1970s. Since then, Jamsil district has begun to be designated as a specialized Olympic town to attract international sports games. It was with this background that the Jamsil district in 1974 was redesigned with a comprehensive plan to build a future-oriented city in pursuit of urbanity, different from a simple residential town built through the conventional land readjustment project. With the decision to host the 1988 Seoul Olympics, the Seoul Metropolitan Government in the 1980s under the leadership of the new military regime, made a full-scale change as an "international city" and "advanced city," corresponding to the motto of "the world to Seoul, Seoul to the world." The Olympic city development plan was realized vigorously through ‘the age of 86 · 88’ mainly in the following two ways: first, the Han River development and the main transportation network establishment projects, such as the development of the Han River estuary site, the construction of the bridge connecting Gangnam and Gangbuk, the urban high-speed road and subway construction in the east-west direction, and second, the urban beautification movement, such as making aesthetic district of Jamsil Olympic Town according to Seoul multi-core city plan and city-wide park-building project. The Olympic city development plan was originated from the national mobilization strategy of the Park Chung-hee regime in the 1960s and 1970s. It was propelled and realized as Jamsil Olympic town by the 5th Republic regime, finally leading to the development of the Gangnam new urban area with a phenomenal scale, speed, and uniformity. In the near future, Gangnam would become a new model of Korean upper-middle class housing.
