본 연구의 목적은 도시안전문제를 순환적이고 통합적으로 분석할 수 있는 지속가능 도시메타볼리즘 패러다임을 개발하고, 개발된 지속가능한 도시메타볼리즘 패러다임을 이용한 도시안전성 평가 프레 임워크를 개발하는 것이다. 이를 위해 본 연구는 도시안전성, 도시안전성 평가, 지속가능한 발전, 도시메타볼리즘 관련 연구를 고찰하였다. 선행연구를 고찰한 결과 본 연구는 지속가능한 도시메타 볼리즘 패러다임을 도출하였고, 도시안전성 평가 프레임워크 개발을 위한 5가지의 원칙을 제시하였 고, 제시된 원칙에 근거하여 지속가능한 도시메타볼리즘을 활용한 도시안전성 평가 프레임워크를 개발하였다. 개발된 도시안전성 평가 프레임워크는 크게 지속가능한 도시메타볼리즘과 도시안전성 의 두 기둥으로 구성되어 있다. 첫 번째 기둥인 지속가능한 도시메타볼리즘은 사회경제시스템과 환경시스템의 두 가지 범주로 구성된 반면, 두 번째 기둥인 환경시스템은 자연재해, 건강, 범죄, 환경 오염, 안전사고 등의 다섯 가지 범주로 구성되었다. 각각의 범주는 구체적인 구성요소들로 구성되었 다. 이들 구성요소들은 향후 도시의 닫힌 계 내에서 도시안전성을 평가하는 과정에서 각각의 요소 간에 인과관계를 파악하는데 사용될 것이다. 본 연구는 도시 안전성 평가 분야에서 지속가능한 도시 메타볼리즘을 활용한 첫 사례가 될 것이다. This study intends to develop a sustainable urban metabolism paradigm which can be used to analyze urban safety problems in the circular and integrated manner and use the paradigm to design an urban safety assessment framework. To reach this goal, this study reviewed previous research related to urban safety, urban safety assessment, sustainable development, and urban metabolism. Based on the literature review, this study derived the paradigm of sustainable urban metabolism, suggested five principles to design the urban safety assessment framework, and used the paradigm to assess urban safety. The framework was composed of two pillars such as sustainable urban metabolism and urban safety. This study would be the first to assess the urban safety using the paradigm of sustainable urban metabolism.

Yong Un Ban,Hye Mi Woo,Kyung Min Han,Jong In Baek 대한환경공학회 2013 Environmental Engineering Research Vol.18 No.3

This study intended to develop an integrated governance model and find measures to manage nonpoint source (NPS) pollutions in watershed management. To reach this goal, this study has analyzed NPS pollution management policies in Korea and has employed statistical methods such as expert Delphi survey, analysis of variance, and factor analysis. As a result, this study has found that the favored basic organization form was a private-public cooperative council. The necessary governance-based NPS pollution management measures determined through this study are as follows: to build collaboration mechanisms including those related to motivation provision, trust building, capacity building, and making optimal regulations; to employ financial resources based on principles such as ``polluter-pays``, ``recipient-pays``, and ``general-tax-source``; and to develop several programs, including system improvement, pilot and management projects, and publicity.

A Study on Fatigue Properties of Sc Added Al 2519 Alloy

Baek, Un Bong,Park, Jong Seo,Chung, In Hyun,Nahm, Seung Hoon,Ma, Young Hwa,Lee, Yong Yun Trans Tech Publications, Ltd. 2005 Key Engineering Materials Vol.297 No.-

<P>The high cycle fatigue properties of two kinds of wrought Al 2519 alloys without and with scandium of 0.10% were investigated. The fatigue strength was determined at R = 0.1 under constant amplitude loading conditions in air. The alloy with scandium of 0.10% showed a little lower tensile yield strength and higher fatigue strength values. The fine grained Al-0.10Sc alloy exhibited a higher resistance against fatigue crack nucleation despite the lower yield stress in comparison to the coarse grained Al 2519 alloy. The results can be explained mainly with the microstructural differences between both alloys. This results are due to the presence of coherent Al3 (Sc, Zr) precipitates and a very fine subgrain structure.</P>

Yong-Joo Hur,Young-Gi Gil,Chul-Jung Baek,In-Ryoung Kim,Un-Bock Jo,Hyun-Ho Kwak,Bong-Soo Park,Gyoo-Cheon Kim 대한해부학회 2008 Anatomy & Cell Biology Vol.41 No.4

Genistein is a naturally occurring isoflavone that has been identified predominantly in soybean. It has been found that genistein can inhibit the growth of various cancer cell lines. Melanoma continues to increase in incidence in many parts of the world and remains among the top six cancers as a cause of death and morbidity. Understanding and overcoming resistance mechanism(s) of melanoma to apoptosis would therefore facilitate identification of new therapeutic targets and development of new treatments. This study was undertaken to investigate whether genistein induced apoptosis on human melanoma cells (G361). Genistein had a significant dose- and time-dependent inhibitory effect on the viability of G361 cells. The death of cells was further demonstrated to be due to apoptosis characterized by chromatin condensation and apoptotic bodies by hoechst staining, and DNA electrophoresis. p53 levels were not altered by genistein treatment. Genistein treatment induced caspase-3 cleavage and activation. Poly (ADP-ribose)-polymerase (PARP) and DNA fragmentation factor 45 (DFF45), which are caspase-3 substrates, were cleaved during genistein-induced apoptosis. It was found that the caspase-6 substrate lamin A was cleaved, whose cleavage has been reported to be necessary for complete condensation of DNA during apoptosis. The expression level and phosphorylation of focal adhesion kinase (FAK) were reduced by genistein treatment. These results suggest that genistein may constitute a potential antitumor compound against melanoma occurring at oral mucosa and skin.

Estimating Reduction Potential by Scenario for Target Setting for Greenhouse Gas Emissions Reduction - Focused on Cheongju City -

Yong Un Ban,Jong In Baek,Ji Hyeong Jeong,Yu Mi Kim,Na Eun Hong 위기관리 이론과 실천 2017 Crisisonomy Vol.13 No.11

본 연구의 목적은 실행 가능한 온실가스 감축목표를 설정하기 위해 가능한 온실가스의 감축잠재량을 산정하기 위한 것이다. 2020년 BAU 대비 온실가스 감축목표가 30%로 설정되어있기 때문에 우리나라는 온실가스 의무감축국이 아니다. 그러나 온실가스 총 배출량 세계 9위(2009년 기준)로 높고, 세계 15위 경제규모를 갖추고 있어 2020년 온실가스 의무감축국에 편입될 가능성이 커지고 있다. 이를 대비한 각 지자체의 역할이 중요해지고 있으며, 지자체는 현실적으로 온실가스 감축목표 설정을 하는 데 노력해야 한다. 이를 위해 본 연구는 총 3단계로 진행되었다. 첫째, 온실가스 감축목표와 감축잠재량, 온실가스 감축목표 설정 방법에 대한 이론적 고찰을 하였다. 둘째, 시나리오 기법을 이용하여 시나리오 별로 감축목표를 설정하였다. 셋째, 각 시나리오의 감축목표별로 감축기법의 적용비율을 설정하여 감축잠재량을 산정하였다. 이러한 결과로 본 연구는 각 시나리오에 따른 감축기법의 적용비율을 적용하여 감축잠재량을 산정하였다. This study intends to estimate reduction potential using scenarios to set a practical target for greenhouse gas (GHG) emission reduction. Since South Korea does not have a mandatory obligation to reduce GHG emissions, its target for GHG reduction is set at 30% of that of BAU in 2020. However, South Korea is increasingly likely to be obliged to reduce its emissions according to 2020 GHG emission target, and thus the local governments should make efforts to set its own realistic reduction target as their roles become more important. This study has proceeded in three stages as follows. First, it reviewed the literature about GHG reduction target, GHG reduction potential, and the relevant methodology for setting GHG emission reduction target. Second, reduction targets were set up by scenario. Third, reduction potential was estimated by setting the application rate of reduction technique for each of the scenarios on a practical target for GHG emission reduction.

This study has intended to build ecological networks in consideration of life-zones inside Cheongju city through biotope grade, GIS network analysis etc. This study consisted of following three steps. First, we selected core districts and core spot districts using land use patten and biotope grade. The core district included the first grade of biotope and forest land. The core district consisted of two sectors: east axis core, Uam mountain; west axis core, Bumo mountain. The core spot district included the first grade of biotope. The core spot districts consisted of two sectors: north axis base core, Myongshim park; south axis base core, Guryong park. Second, the base district included the second grade of biotope and park and school. We used buffering analysis within 500m of the base district and selected the new base district. Third, we connected core districts and base core districts using least cost analysis of GIS. Thus we built comprehensive ecological networks in consideration of life-zones through GIS.
