[Oral Session 4] Water Reuse and Effluent Treatment in the De-inking Process
T.Saigusa,T.Sugi 한국펄프·종이공학회 1999 한국펄프종이학회 기타 간행물 Vol.- No.-
Effluent resulting from the de-inking process is difficult to treat because it has a high pH value and contains many anionic constituents such as ink particles, fine suspended solids and surfactants used in the de-inking process. However, as much water is used in this process, it is becoming increasingly more important to recover the effluent and reuse it from viewpoints of both water conservation and quality improvement of de-inked pulp.<br/> This article describes the coagulation method, using a polycation instead of alum as a new recovering technology with waste water, can get rid of fine particles and suspended solids which cannot be removed by flotation methods, giving clear recycling water. As a result it has such advantages as high brightness, good strength, and so on.

Background/Aims: Recent developments in analytical techniques including next-generation sequencing have clarified the correlation between intestinal microbiota and inflammatory bowel disease. Fecal microbiota transplantation (FMT) for patients with ulcerative colitis (UC) is proposed as a potential approach to resolving their dysbiosis; however, its safety and efficacy have not been confirmed. This single-arm, open-label, non-randomized study aimed to evaluate the safety and efficacy of FMT for Japanese patients with UC as the first registered clinical trial in Japan. Methods: We enrolled 10 patients with active UC despite medical therapy. The donors were the patients` relatives and were carefully screened for infectious diseases. Fecal material was administered via colonoscopy, and the primary endpoint was the presence or absence of serious adverse events related to FMT. The secondary endpoint was a change in partial Mayo score at 12 weeks post-FMT. Scores ≤2 were considered a clinical response. Fecal samples were collected to follow changes in gut microbiota, while extracted complementary DNA were analyzed by a next-generation sequencer. We obtained written informed consent from all patients and donors. This study was approved by our Institutional Review Board and is registered in the University hospital Medical Information Network (UMIN) Clinical Trials Registry (UMIN 000012814). Results: Five patients with moderate disease and five with severe disease were enrolled. No severe adverse effects were observed. One patient achieved clinical response; however, none of the patients` microbiota diversity recovered to the donor levels. Conclusions: The use of single FMT for UC was safe; however, we failed to show its clinical efficacy and potential to change the intestinal microbiota. (Intest Res 2017;15:68-74)

Background/Aims: 5-Aminosalicylic acid (ASA) causes intolerance reactions in some patients. This study was performed to examine the prognosis of patients with ulcerative colitis (UC) and 5-ASA intolerance, and to evaluate the potential interaction between 5-ASA intolerance and the intestinal microbiota. Methods: We performed a retrospective cohort study of patients with UC who visited participating hospitals. The primary endpoint was to compare the incidence of hospitalization within 12 months between the 5-ASA intolerance group and the 5-ASA tolerance group. The secondary endpoint was to compare the risk of adverse clinical outcomes after the start of biologics between the 2 groups. We also assessed the correlation between 5-ASA intolerance and microbial change in an independently recruited cohort of patients with UC. Results: Of 793 patients, 59 (7.4%) were assigned to the 5-ASA intolerance group and 734 (92.5%) were assigned to the 5-ASA tolerance group. The admission rate and incidence of corticosteroid use were significantly higher in the intolerance than tolerance group (P<0.001). In 108 patients undergoing treatment with anti-tumor necrosis factor biologics, 5-ASA intolerance increased the incidence of additional induction therapy after starting biologics (P<0.001). The 5-ASA intolerance group had a greater abundance of bacteria in the genera Faecalibacterium, Streptococcus, and Clostridium than the 5-ASA tolerance group (P<0.05). Conclusions: In patients with UC, 5-ASA intolerance is associated with a risk of adverse clinical outcomes and dysbiosis. Bacterial therapeutic optimization of 5-ASA administration may be important for improving the prognosis of patients with UC. (Intest Res 2020;18:69-78)
동아시아 지역의 플럭스 타워 관측지에 대한 MODIS 위성영상 기반의 증발산 평가

지표 증발산은 육상 생태계의 수문순환의 주요 성분으로서, 지표-대기간의 에너지 교환, 미기후, 지역의 수자원 함량, 식생의 일차생산성 등에 중요한 영향을 미친다. 증발산을 추정하기 위한 방법들 중에서 MODIS를 이용한 방법은 위성 자료만을 사용하여 넓은 지역에 대한 지속적인 증발산 모니터링이 가능하다는 장점을 갖고 있다. 본 연구에서는 MODIS 기반의 증발산 추정 알고리즘을 동아시아 지역에 적용하고, 그 신뢰도를 평가하였으며, 주요 오차요인을 분석하였다. 증발산 평가 결과 여섯 연구지역(GDK, HFK, TKY, TMK, CBS, SKT)에서는 $r^2$가 0.38~0.73, ME 와 RMSE가 각각 $-44{\sim}+31W\;m^{-2}$, $48{\sim}111W\;m^{-2}$로 신뢰할 만한 결과를 나타냈다. 하지만 다른 세 연구지역(HBG, QYZ, MKL)에서는 관측 값과 비교해서 차이를 나타내었고, 과소평가하는 경향을 보였다. HBG, MKL 지역은 MODIS 기상 자료 및 복사요소의 오차가 주요 원인으로 나타났다. 그러나 QYZ지역은 기상 자료와 복사요소가 모두 좋은 일치도를 보였기 때문에, 모형의 모수와 관련된 오차가 주요 원인의 하나로 판단된다. 임관 전도도의 오차가 증발산 오차에 미치는 영향을 분석한 결과, HBG지역을 제외한 다른 연구지 역에서 r값이 0.59~0.82로 관측값과의 상관성이 높은 것을 확인하였다. 또한 MODIS로부터 산출된 순간 증발산을 일 단위로 확장시킨 결과, 순간 증발산의 일치도가 떨어졌던 3개 연구지역을 제외하고 6개 지역에서 $r^2$가 0.44~0.89, ME와 RMSE는 각각 $-0.7{\sim}+0.6mm\;day^{-1}$, $0.5{\sim}1.1mm\;day^{-1}$의 범위로 신뢰도 있는 결과를 나타냈다. Evapotranspiration (ET) is one of the major hydrologic processes in terrestrial ecosystems. A reliable estimation of spatially representavtive ET is necessary for deriving regional water budget, primary productivity of vegetation, and feedbacks of land surface to regional climate. Moderate resolution imaging spectroradiometer (MODIS) provides an opportunity to monitor ET for wide area at daily time scale. In this study, we applied a MODIS-based ET algorithm and tested its reliability for nine flux tower sites in East Asia. This is a stand-alone MODIS algorithm based on the Penman-Monteith equation and uses input data derived from MODIS. Instantaneous ET was estimated and scaled up to daily ET. For six flux sites, the MODIS-derived instantaneous ET showed a good agreement with the measured data ($r^2=0.38$ to 0.73, ME = -44 to $+31W\;m^{-2}$, RMSE =48 to $111W\;m^{-2}$). However, for the other three sites, a poor agreement was observed. The predictability of MODIS ET was improved when the up-scaled daily ET was used ($r^2\;=\;0.48$ to 0.89, ME = -0.7 to $-0.6\;mm\;day^{-1}$, $RMSE=\;0.5{\sim}1.1\;mm\;day^{-1}$). Errors in the canopy conductance were identified as a primary factor of uncertainty in MODIS-derived ET and hence, a more reliable estimation of canopy conductance is necessary to increase the accuracy of MODIS ET.
