We tried to induce the fusion of plasma membrane and intracellular low density microsomal membrane, and evaluated about the regulatory factors(insulin, cytosol, ATP, GTP, incubation time and temperature) which may affect the fusion and movement of the glucose transporter 4(GLUT 4). We obtained the results as follows; 1) Membrane-associated fusion might be fairely well established, and we could confiremd that fact by western analysis. 2) Insulin stimulated the fusion and movement of the GLUT 4. 3) Cytosol showed the tendency to increase the fusion and movement of the GLUT 4, but its effect was not apparent. 4) Other regulatory factor such as ATP, GTP, incubation time and temperature did not affect to the fusion and movement of the GLUT 4. 5) There might be somewhat non-specific reaction when separate the plasma mem-brane and intracellular low density microsomal membrane after fusion. In conclusion, insulin apparently stimulated the fusion and movement of the GLUT 4, but ATP, GTP, incubtion time and temperature did not. Further study to reseparate more specifically the PM and LDM after fusion must be required to clarify the exact effects of various regulatory factors.

조창우,유재웅,정팔진 한국물환경학회 2004 한국물환경학회지 Vol.20 No.6

The objective of this study was to remove organics and color in livestock wastewater using coagulation and Fenton oxidation process. After coagulation process as 1^(st) treatment, organics in 1^(st) treatment water were removed by using OH radical produced in Fenton oxidation process. Removal efficiencies of COD_(Mn) and color were 87.2% and 95.7% separately. At that time, the ratio of Fe^(2+)/ H₂O₂ was 0.8∼1.0, and range of reaction pH was effective at the pH of 3.5∼3.8. The Reaction time of 120min more than 60min or 90min was sufficient in Fenton process. Removal efficiency of organics was higher two- or multi-stage treatment than one-stage treatment.

<P><B>Abstract</B></P> <P>Understanding the influence of land use and land cover (LULC) change in stormwater runoff is important for watershed management. In this study, integration of 31 storm events, monthly monitoring of LULC change, Pearson’s correlation, multiple linear regression analysis (MLR) and Personalized Computer Storm Water Management Model (PCSWMM) were applied to quantify the influence of LULC change on stormwater quality from mixed LULC catchment with ongoing land development in Yongin, South Korea. Due to ongoing land development in the catchment, bare land and urban LULC were exponentially increased while agriculture, forest, grassland and water LULC decreased in spatial extent. The correlation analysis showed that stormwater quality was positively correlated to bare land (0.595; Cl – 0.891; TSS, <I>p</I> < 0.05) and urban (0.768; TN – 0.987; TSS, <I>p</I> < 0.05); negatively correlated to forest (−0.593; Cu – 0.532; BOD<SUB>5</SUB>, <I>p</I> < 0.05) and grassland (−0.587; TSS – 0.512; BOD<SUB>5</SUB>, <I>p</I> < 0.05) and; either positively or no correlation to agriculture (0.064; Cu – 0.871; TSS, <I>p</I> < 0.05) and water (−0.131; Cl – 0.221; TP, <I>p</I> < 0.05). Furthermore, the MLR analysis showed that combinations of different LULC were able to describe the overall stormwater quality of the catchment. Moreover, the LULC scenario analysis demonstrate that under dominant agriculture (S1), bare land (S2) and urban areas (S5), the average pollutant concentrations would increase by as much as 13.22% (Cl; S2; pre-) to 59.25% (TSS; S5; early-active); while under dominant forest (S3) and grassland (S4) the average pollutant concentration would decrease by as much as −53% (Pb; S3; late-active) to −3.22% (BOD<SUB>5</SUB>; S4; pre-). These findings explained that the variability of pollutant concentrations in different phase of land development was affected by expansion of bare land and urban spatial extent, increase of hydrological characteristics (total rainfall and average rainfall intensity) and massive soil activities (soil digging and soil transfer). Therefore, results of this study will provide scientific information to establish a cost-effective stormwater management, development of empirical model, and designing monitoring strategies and guidelines to minimize the negative impact of LULC change on stormwater runoff.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Long-term LULC and stormwater monitoring advanced the current watershed management. </LI> <LI> PCSWMM was used to evaluate the influence of land development on stormwater runoff. </LI> <LI> Land development influences the variability of pollutant concentration in runoff. </LI> <LI> Conversion of vegetation to bare land and urban is the major stormwater stressor. </LI> <LI> Expansion of vegetation cover was not enough to achieve the water quality criteria. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Candlelight Protests in South Korea

Paul Y. Chang 이화여자대학교 이화사회과학원 2018 사회과학연구논총 Vol.34 No.1

The recent candlelight protests in the fall and winter of 2016 and 2017 marked a critical moment in the maturation of South Korean democracy. Through complex connections between contributing actors involving the protesting public, the National Assembly, and the Constitutional Court of the Republic of Korea, President Park Geun-hye became the first South Korea president to be impeached through democratic procedures. While acknowledging the significant differences that distinguish this most recent protest wave with contentious politics of the past, this article highlights the foundational legacies of South Korea’s authoritarian history. In addition, I reflect on how the contemporary candlelight protest industry draws on organizational and cultural resources first established in past democracy movements. In short, the political contest that brought down Park Geun-hye in 2016-2017 was in some tangible and intangible ways a reenactment of the authoritarian and democratization legacies that dominated much of South Korea’s modern history.

오늘날 지속된 경제 저성장을 대처하기 위하여 세계 각국은 신 성장 동력으로 4차 산업혁명에 주목하고 있다. 전세계 각국과 각 산업에 걸쳐 인공지능기술이 심화되는 변화는 필연적 과정이며, 이것은 산업지도의 재편과 향후 인간의 삶을 바꾸어 놓을 수 있는 중요한 이슈이다. 일반적으로 산업화 과정은 생산성의 증대, 분업화, 시장의 고도화를 바탕으로 제조업 위주의 1차 산업에서 2차, 3차 산업의 비중이 높아지는 현상과 변화를 보이고 있다. 인공지능은 미래시대의 유일한 대항(대응) 산업이라는 측면에서 산업 활성화의 당위성은 충분하다. 글로벌 산업을 추구하는 기업들은 혁신성과를 개선하는 목적으로 경제적인 성장과 생산성 향상목표를 달성하기 위해 각 기업체마다 협업하면서 전략적 접근방법과 연구개발 등에 집중할 필요가 있다. 본 연구는 4차 산업혁명의 관점에서 일본, 미국, 독일, 중국 등의 로봇산업과 경제의 융합 활성화 방안을 모색하는데 목적이 있다. 본 연구의 결과, 기존의 자금지원이 아니라 기술지원이나 혁신적인 비즈니스모델의 창출을 지원하는 창업지원정책을 간구해야 한다. 혁신적인 창업정책은 지역경제를 활성화시키며 미래의 고부가가치산업을 육성시킬 수 있으며, 나아가서 일자리 창출에도 기여할 수 있을 것이다. In order to cope with the economic slowdown that continues today, countries around the world are paying attention to the fourth industrial revolution as a new growth engine. The deepening of AI technology across countries and industries around the world is an inevitable process, which is an important issue that can reshape industrial maps and change human life in the future. In general, the industrialization process is from the primary industry focused on the manufacturing industry to the secondary and tertiary industries based on the increase of productivity, the division of labor and the advancement of the market. In the sense that AI is the only counter industry in the future, the justification for industrial activation is sufficient. Companies seeking a global industry need to focus on strategic approaches and research and development while collaborating with each company to achieve economic growth and productivity goals with the aim of improving innovation performance. This study aims to find ways to revitalize the convergence of the robot industry and economy in Japan, the United States, Germany and China from the perspective of the Fourth Industrial Revolution. As a result of this study, we should ask for a start-up support policy that supports the creation of technical support or innovative business model, rather than existing funding. As a result of this study, we should ask for a start-up support policy that supports the creation of technical support or innovative business model, rather than existing funding. Innovative entrepreneurship policies can stimulate local economies, foster future high value-added industries, and contribute to job creation.
