PAHs (Polycyclic Aromatic Hydrocarbons: PAHs) is the hydrophobic inorganic material composed of carbon and hydrogen that is easily adsorbed biological organisms in the ocean. Bivalves is the indicator of environment monitoring because of reflect growth, physiological response of bivalve followed their habitat environment. The aim of research is understand the change of oysters (Crassostrea gigas) physiological response under exposed PAHs concentration for control, 1, 10 and $100{\mu}g/L$. We investigated induced immune change response for oyster hemocyte and effect of tissue RNA/DNA ratio for mantle, gill and adductor muscle individually. As a result of experiment change of immune response the oyster hemocyte when exposed PAHs showed that viability and adhesion is no significant difference (ANOVA test, p < 0.05). However phagocytosis decreased under the over $10{\mu}g/L$ of PAHs concentration and ROS increased with the increase of PAHs concentration. The change of RNA/DNA ratio is R/D ratio decreased with the increase of PAH concentration in adductor muscle. However gill and mantle showed no change of R/D ratio with PAHs concentration. The oysters when exposed inorganic pollutant that decreased of physiological condition and damaged protein synthesis of adductor muscle.

Excessive emission of greenhouse gases from fossil fuels usage has become a major cause of climate change. As an alternative to reduce the greenhouse gas emission, renewable energy has been highlighted around the world and UK government also established the Climate Change Act 2008 and policies for response the climate change. Those of them has been supporting many practical actions for reducing greenhouse gas emission and community energy projects is representative program to supporting security of energy supply and helping the country to reduce its carbon footprint. Rural Community Energy Fund (RCEF) which is one of community energy projects supports rural communities to develop renewable energy projects which provide economic and social benefits to the community. The review of UK's renewable energy policies and action plan can be useful to promote in Korea policies for becoming low-carbon society.

네덜란드 브리젠빈 하폐수처리장 최종방류수의 $NH_4$-N 및 TN(Total Nitrogen)농도를 방류수 수질기준인 각각 4 mg/L와 10 mg/L에 맞추기 위한 최적의 운전조건을 도출하기 위해 다양한 제어시스템이 시뮬레이션 되었다. 본 연구에 사용된 모델은 IWA(International Water Association) 활성슬러지 모델 No.1 (ASM No.1)이었고, GPS-X가 시뮬레이터로 사용되었다. 모델링을 위한 매개변수 민감도 분석결과 ASM No.1의 총 19개 매개변수 중 8개 변수 ($Y_H$, ksh, koh, $b_H$, ${\mu}_a$, $k_{NA}$, kh, ka)가 방류수 수질에 영향을 미치는 것으로 조사되었고 이들 매개변수에 대해 보정을 수행하여 사용하였다. SRT, 호기/무산소기간, 외부탄소원 주입시간 변화에 따른 방류수질 변화를 시뮬레이션하였는데, 호기/무산소 11h/1h인 조건에서 SRT가 20일에서 25일로 증가되면 $NH_4$-N가 5.0 mg/L에서 2.9 mg/L로 감소되었고 호기/무산소 2h/1h의 조건에서는 SRT증가에 따라 $NH_4$-N은 큰 감소를 보이지만, 바이패스되는 유입수량의 감소로 탈질율이 낮아 방류수 TN이 11.1~11.5 mg/L로 예측되는 결과가 도출되었다. 탈질율을 높이기 위한 아세트산 주입은 동일한 양의 아세트산을 무산소 전기간 (1h)동안 균일 주입하는 것 보다는 무산소 초기 15분내에 주입하는 것이 효율적인 것으로 나타났다.

In order to effectively manage the reservoir, reservoir water quality management should be based on physicochemical and configurational characteristics. In this research, correlation between factors affecting the reservoir water quality was examined. Chl-a and COD shows the highest positive correlation. Chl-a and T-P also has a high positive correlation, however Chl-a and T-N show lower correlation relatively. Even though T-N is an important factor for phytoplankton growth which increase Chl-a concentration, corelation of Ch1-a and T-N shows that enough nitrogen in the reservoir isn't no longer limiting factor. The age of reservoir can cause of increasing COD and SS. Embankment height and elevation of reservoirs shows strong negative correlation to water quality. That means reservoir which is higher embankment height and locate in higher elevations is less contaminated. Regression expression was derived with Chl-a and water quality parameters, and height of reservoir. Finally Chl-a was simulated using regression expression and it was a good approach to predict the Chl-a concentration.

Purpose: The purpose of this study was to test the predictive validity of the Fall Assessment Scale-Korean version (FAS-K) and to find the most appropriate cutoff score to screen high-risk fall groups in adult patients in general hospitals in Korea. Methods: We performed a prospective evaluation study in medical and surgical ward patients at two major general hospitals in Seoul. Data were collected from Nov. 1, 2018 to Feb. 28, 2019, nurses performed 651 observation series. The researcher measured the fall risk assessment score by applying FAS-K, MFS (Morse Fall Scale), and JHFRAT (Johns Hopkins Hospital Fall Risk Assessment tool) to the patients twice a week between 10 am and 12 noon. Data were analyzed using Pearson's corelation coefficients, and the sensitivity, specificity, predictive value, and the area under the curve (AUC) of the three tools. Results: The FAS-K was positively correlated with the MFS (r=.70, p<.001) and the JHFRAT (r=.82, p<.001). According to the receiver operating characteristics (ROC) curve analysis of the FAS-K, sensitivity, specificity, and positive and negative prediction values were 85.3%, 49.4%, 8.5%, and 98.4%, respectively, when the FAS-K score was 4. Therefore, the cut-off score of the FAS-K to identify groups with high fall risk was 4. Conclusion: The FAS-K is a valid tool for measuring fall risk in adult inpatients. In addition, the FAS-K score, 4, can be used to identify high-risk fall groups and know specific points in time to provide active interventions to prevent falls.

수도권 보금자리주택 대상계층의 지불가능성 분석: 공공분양, 10년임대, 분납임대주택을 중심으로

최은희,김옥연,이종권,Choi, Eun-Hee,Kim, Ok-Yeon,Lee, Jong-Kwon 한국토지주택공사 토지주택연구원 2013 LHI journal of land, housing, and urban affairs Vol.4 No.4

본 논문의 목적은 대상계층을 설정하고 유형별 공공주택을 공급하는 보금자리주택을 평가해 보기 위한 것이다. 특히 수도권 보금자리지구가 지정되고 보금자리주택 공급이 발표되면서, 정책대상계층의 접근성에 대한 논의가 불거졌는데, 본 연구에서는 등장한 여러 논의 중에서 두 가지에 주목하였다. 하나는 주변시세애 비해 과도하게 낮게 책정된 분양가 혹은 임대료로 인해 청약에 당첨된 입주자에게 역시 과도한 개발이익 수혜가 돌아가는 것이 아니냐는 것이고, 다른 하나는 그렇게 낮게 책정된 분양가 혹은 임대료라고 하더라도 일부 지역의 경우 주변 시세가 워낙 높아, 저소득층이나 무주택 서민인 정책대상계층이 접근하는 것이 쉬울 것인가 하는 것이다. 두 가지 논의는 완전히 다른 것 같으면서도 다르지 않다. 상대적인 가격에서는 우위를 점하지만, 절대적인 가격에서는 여전히 낮지 않다고 보는 것이기 때문이다. 본 연구는 이 두 가지 논의에 착안하여 분석을 시도하였다. 특히 보금자리주택은 저소득층을 위한 장기공공임대주택(국민임대주택, 영구임대주택 등) 뿐 아니라 공공분양주택과 유사한 역할을 하는 10년임대주택과 분납임대주택도 존재하는 점을 감안하여 이 세 가지 유형에 대해 정책대상계층의 지불가능성이 어느 정도인지 파악하고자 하였다. 유형별, 지역별, 면적별 지불가능성의 차이를 비교해 봄으로써 기존의 논의에 대한 의문을 어느 정도 해결해 보려고 했으며, 향후 공공주택 공급 프로그램과 관련한 정책적 시사점도 도출해 보고자 하였다. The purpose of this paper is to appraise Bogeumzari Housing Program(BHP) which is providing public housing of different types for the target brackets on a matching system basis. Especially, on government's announcing BHP plan with the designation of several Bogeumzari districts in Seoul Metropolitan area, they raised a question about target groups' receiving the benefits of BHP plan and this paper focuses on the question. We tried to analyze two topics. First one is about the exorbitant windfall profits to the future potential residents derived from low price or rental cost of Bogeumzari Housing in comparison with neighborhood's market price. Second one is the low possibility of low-moderate income household's access to absolutely high price Bogeumzari Housing that is because the market price is so high in some area. BHP includes not only long-term public rental hosing(Permeant rental housing, National rental housing) for low income households but also other types of public rental housing(10-year rental housing, shared-ownership rental housing) for moderate income households. So, in this study we tried to find out the affordability of each bracket in three public housing types, which are public sales housing(condominium), 10-year rental housing and shared-ownership rental housing. Through analyzing the housing affordability by types, regions, size, we tried to seek the answer to the controversy and propose policy implications related to the future public housing programs.

The 21 livestock farms considering future installation of biogas systems were studied. These farms were examined how to raise the livestock, to treat manure, to operate facility with respect to manure characteristics. The 15 farms out of 21 farms have applied to the marine dumping and consignment treatment for treating manure and even farms which have equipped liquid fertilizing system have less capacity facility than legal standards. Characteristics of manure were affected by the scale of swine barn, clean water usage, frequency of cleaning, cleaning method, feces-urine separating method, etc. Retention time in storage (over 20 days) has resulted in lower concentration of organic matter which could reduce biogas production. This indicates that systematic barn management system is required. Inhibition tests showed that disinfectant and citric acid did not affected digestion rates at 10 times higher concentration than recommendation. However hypochlorous acid is likely to affect the anaerobic microbial activity.
