Community structure of heterotrophic protists and their grazing impact on phytoplankton were studied in Northwest Pacific Ocean during October, 2007. The study area was divided into four regions based on physical properties (temperature and salinity) and chlorophyll-a distribution. They were Region I of North Equatorial Currents, Region II of Kuroshio waters, Region III of shelf mixed water, and Region IV of Tsushima warm current from East China Sea. The distribution of chlorophyll-a concentrations and community structure of heterotrophic protists were significantly affected by physical properties of the water column. The lowest concentration of chlorophyll-a was identified in Region I and II, where pico-sized chlorophyll-a was most dominant (>80% of total chlorophyll-a). Biomass of heterotrophic protists was also low in Region I and II. However, Region III was characterized by low salinity and temperature and high chlorophyll-a concentration, with relatively lower pico-sized chlorophyll-a dominance. The Highest biomass of heterotrophic protists appeared in Region III, along with the relatively less important nanoprotists. In Region I, II and IV, heterotrophic dinoflagellates were dominant among the protists, while ciliates were dominant in Region III. Community structure varied with physical (salinity and temperature) and biological (chlorophyll-a) properties. Biomass of heterotrophic protists correlated well with chlorophyll-a concentration in the study area (r2 = 0.66, p<0.0001). The potential effect of grazing activity on phytoplankton is relatively high in Region I and II. Our result suggest that biomass and size structure of heterotrophic protists might be significantly influenced by phytoplankton size and concentration.

양은진,김민선,김승영,현창구 한국생물공학회 2019 KSBB Journal Vol.34 No.2

The Euphorbia jolkini (J11) is traditional medicinalplant, has been used for treatment diabetes, flu, toothache,etc. Recently studies shown that J11 extract has been evaluatedto anti-oxidant, anti-bacterial, and anti-melanogenesis. However, Anti-inflammatory effect of J11 extract has notbeen reported yet. In this study, we studied the effects of J11extract on anti-inflammatory effect in lipopolysaccharide(LPS)-stimulated RAW 264.7 cells. We also studied the effectof J11 extract on expression of protein in RAW 264.7 cells. The cells were treated with J11 extract, ranging between 25and 100 μg/mL. The results indicated that J11 extract dramaticallydecreased nitric oxide (NO) and prostaglandin 2 (PGE2)production in the cells without any cytotoxicity. In addition,J11 extract strongly inhibited expression of pro-inflammatorycytokines such as interleukin (IL)-6 and interleukin (IL)-1β. Moreover, western blot result showed that the J11 extractinhibited inducible nitric oxide synthase (iNOS) and cyclooxygenase(COX-2) expression in a does-dependent manner. Therefore, this study suggest that J11 extract may be appliedfor potential source as a natural anti-inflammatory agent.

Background: Clinical deteriorations during hospitalization are often preventable with a rapid response system (RRS). We aimed to investigate the effectiveness of a daytime RRS for surgical hospitalized patients. Methods: A retrospective cohort study was conducted in 20 general surgical wards at a 1,779- bed University hospital from August 2013 to July 2017 (August 2013 to July 2015, pre-RRSperiod; August 2015 to July 2017, post-RRS-period). The primary outcome was incidence of cardiopulmonary arrest (CPA) when the RRS was operating. The secondary outcomes were the incidence of total and preventable cardiopulmonary arrest, in-hospital mortality, the percentage of “do not resuscitate” orders, and the survival of discharged CPA patients. Results: The relative risk (RR) of CPA per 1,000 admissions during RRS operational hours (weekdays from 7 AM to 7 PM) in the post-RRS-period compared to the pre-RRS-period was 0.53 (95% confidence interval [CI], 0.25 to 1.13; P=0.099) and the RR of total CPA regardless of RRS operating hours was 0.76 (95% CI, 0.46 to 1.28; P=0.301). The preventable CPA after RRS implementation was significantly lower than that before RRS implementation (RR, 0.31; 95% CI, 0.11 to 0.88; P=0.028). There were no statistical differences in in-hospital mortality and the survival rate of patients with in-hospital cardiac arrest. Do-not-resuscitate decisions significantly increased during after RRS implementation periods compared to pre-RRS periods (RR, 1.91; 95% CI, 1.40 to 2.59; P<0.001). Conclusions: The day-time implementation of the RRS did not significantly reduce the rate of CPA whereas the system effectively reduced the rate of preventable CPA during periods when the system was operating.

: As a part of Korea Deep Ocean Study program, we investigated the distribution of planktonic protists in the upper 200 m of the northeast Pacific from 5oN to 17oN, along 131o30'W. Area of divergence was formed at 9oN which is boundaries of the north equatorial counter current (NECC) and the north equatorial current (NEC) during this cruise. Chlorophyll-a concentration was higher in NECC than in NEC area. Pico chl-a(<2 mm) to total chl-a accounted for average 89% in the study area. The contribution of pico chl-a to total chl-a was relatively high in NEC area than in NECC area. Biomass of planktonic protists, ranging from 635.3 to 1077.3 mgC m-2(average 810 mgC m-2), was most enhanced in NECC area and showed distinct latitudinal variation. Biomass of HNF ranged from 88.7 to 208.3 mgC m-2 and comprised 15% of planktonic protists. Biomass of ciliates ranged from 123.6 to 393.0 mgC m-2 and comprised 25% of planktonic protists. Biomass of HDF ranged from 407.2 to 607.8 mgC m-2 and comprised 60% of planktonic protists. HDF was the most dominant component in both NECC and NEC areas. Nano-protist biomass accounted for more than 50% of total protists in the both areas. The contribution of nanoprotist to total protists biomass was relatively higher in NEC area than in NECC. The biomass of planktonic protists was significantly correlated with phytoplankton biomass in this study area. The size structure of phytoplankton biomass coincided with that of planktonic protists. This suggested that the structure of the planktonic protists community and the microbial food web were dependent on the size structure of the phytoplankton biomass. However, biomass and size structure of planktonic protist communities might be significantly influenced by physical characteristics of the water column and food concentration in this study area.

The 17 Sustainable Development Goals(SDGs) consist of 169 targets launched in 2015 to provide inclusive, safe and sustainable development in cities and human settlements and make sure that no one is left behind. SDGs are new universal agendas that are integrated and indivisible and balance economic, social and environmental dimensions. Due to unprecedented urbanization, cities are the hotspot of the COVID-19 Pandemic and have been the centre of global issues including climate change, poverty, and inequality. To tackle these global challenges, an urgency to implement SDGs is recognized. Cities evolved to content public interest by satisfying public needs and wants, but each city has its own social, political, economical and environmental context which generally leads to a different level of development and hence the ability to achieve sustainable development goals. Therefore, in this research, SDGs and urban development in the context of public interest are analyzed and SDGs that needs to be prioritized for each Urban Development stage are suggested. This research is divided into four parts, In step one, the concept and definition of public interest are studied through literature review to provide the conceptual idea of public interest and identify the public interest of the current era. In the second step, SDGs' background and purpose are explained to identify key areas of each sustainable development goal. In the third step, urban development history is studied and explained based on the public interest to provide four stages of urban development. The last stage of this research comprises a detailed interrelationship between SDGs and urban development stages. This paper provides guidelines for all countries at different stages of urban development when implementing SDGs by illustrating SDGs that must be prioritized at each stage of urban development. This research supports that cities developed to support the public interest and SDGs being the public interest of the current era, the universal guideline is developed to implement SDGs effectively and efficiently.

The purpose of this study is to identify interrelationship between advanced technology and Urban activity in order to understand theimportance of considering the context of public space and urban activities during the implementation of advanced technologies. This studyanalyzes advanced technology based on globally recognized oversea and local company case, and then direct relationship between urbanactivity and advanced technology is determined. Based on the analyzation, top six advanced technologies were Artificial Intelligence,Blockchain, Internet of Things, Autonomous Vehicle, Extended Reality and 5G. And urban activities interlinked with identified advancedtechnologies were Maintenance, Transaction, Place Information, Mobility, Event and Interaction. Hence, correlation between advancedtechnology and urban activity proves the multi-relationship between urban activities, public space and technologies which is in turn theevolution theory of the city. Finally, this paper shows the importance of considering urban activities when implementing advanced technologyinto the public space to eliminate unwanted situation primitively. 도시의 공공공간은 물리적 환경으로써 인간의 필수적, 선택적 그리고 사회적 활동을 지원하고 도시문제를 해결하기 위해 지속적으로 발전해 왔으며 가로는 도시의 공공공간 중 도시를 구성하는 필수적 요소로 발전해 왔다. 역사적으로 가로 활동을 반영한 도시계획이 중요하게 여겨져 왔지만, 제4차 산업 혁명으로 인한 혁신적인 기술 개발로 인해 가로 공간에서 보행자의 활동과 수요를 반영하지 않고 첨단 기술 도입에만 초점을 둔 공급자 중심의 개발이 이어지고 있는 현실이다. 이로써, 본 연구는 첨단기술의 적용에 있어 우선적으로 고려해야 할 공공공간에서의 도시민 활동을 도출하기 위해 미래의 핵심 첨단 기술과 공공공간에서의 도시민 활동 간의 상관관계를 분석하였다. 본 연구에서는 사례조사를 통하여 미래의 핵심 첨단 기술로 인공지능, 블록체인, 사물인터넷, 5G, 자율주행차 그리고 확장 현실을 도출하였으며 도시민의 활동 중 유지관리, 거래, 장소정보, 교류, 이동 그리고 이벤트 등과 직접적으로 연관이 있는 것으로 도출되었다. 이는 미래의 핵심 첨단 기술과 도시민의 활동 간의 상관관계를 증명하며, 향후 공공공간에서의 도시민 활동을 고려한 미래의 첨단 기술 도입의 필요성을 보여준다.
