장성지역 잔디 재배지에서 총생 증상의 들잔디가 발생하였다. 총생 증상의 들잔디는 작고 다발형태로 유의한 형태적인 변화를 보였고, 병징은 여러 개의 잎이 짧은 포복경 마디에 무더기로 발생되어 빗자루처럼 총생 형태를 보였으며, 총생 형태의 잔디는 잎이 황화되면서 연녹색이나 노란색을 띄었다. 총생 증상을 보이는 들잔디는 건전한 들잔디에 비해 포복경 1개 마디당 약 5.8배 이상의 잎이 발생하였다. 또한 과도한 지상부 생육으로 인해 포복경과 지하부 생장이 저조하였다. 총생 병징의 들잔디를 채집하여 병원균을 배양한 후 관찰한 결과 포자낭의 모양은 레몬모양이었으며, 포자낭 축의 끝이 뾰족하게 튀어나와 있었고, 크기는 $60{\sim}96{\times}42{\sim}51{\mu}m$로 관찰되었다. 이는 Sclerophthora macrospora 병원균이 형성하는 포자낭의 균학적 특징과 유사하였고, 봄과 가을에 병징을 확인할 수 있었다. 따라서 본 연구를 통하여 국내 잔디 재배지 총생 증상에 대한 기초적인 자료를 제시하고자 한다.

It is a recent observation that about 80 per cent of the body's immune system is localized in the gastrointestinal tract. This explains to a large extent why eating right is important for the modulation the immune response and prevention of disease. In addition it is increasingly recognized that the body has an important digestive system also in the lower gastrointestinal tract where numerous important substances are released by microbial enzymes and absorbed. Among these substances are short chain fatty acids, amino acids, various carbohydrates, poly-amines, growth factors, coagulation factors, and many thousands of antioxidants, not only traditional vitamins but numerous flavonoids, carotenoids and similar plant- and vegetable produced antioxidants. Also consumption of health-promoting bacteria (probiotics) and vegetable fibres (prebiotics) from numerous sources are known to have strong health-promoting influence. It has been calculated that the intestine harbours about 300,000 genes, which is much more than the calculated about 60,000 for the rest of the human body, indicating a till today totally unexpected metabolic activity in this part of the GI tract. There are seemingly several times more active enzymes in the intestine than in the rest of the body, ready to release hundred thousand or more of substances important for our health and well-being. In addition do the microbial cells produce signal molecules similar to cytokines but called bacteriokines and nitric oxide, with provide modulatory effects both on the mucosal cells, the mucosa- associated lymphoid system (MALT) and the rest of the immune system. Identification of various fermentation products, and often referred to as synbiotics, studies of their role in maintaining health and well-being should be a priority issue during the years to come.

Approximately 10 percent of advanced stomach cancer patients have internal bleeding in their stomach. It is crucial to treat internal bleeding since it severely deteriorates patient's condition, and disturbs process of chemotherapy. There are hemostatic agents and dressing, radiotherapy, endoscopic ligation and coagulation, surgical methods to treat bleeding. However, these methods cannot be executed in some cases in which patient is in terminal stage or not in desirable condition to take these treatments. We are going to introduce a case of advanced gastric cancer patient having stomach bleeding who made a choice to take oriental medical treatments. The patient was on third stage of stomach cancer, had 3200cc of blood transfusion for five times. After diagnosed as not being able to have resection, he started to oriental medical treatments to stop bleeding. From March 28, 2009 to April 16, 2009, we administer 120cc Bojungikgi-tang gamibang to the patient in 90minutes after each meal. During 19days of having Bojungikgi-tang gamibang, we observed that the patient needed significantly lower amount blood transfusion, to 640cc. The patient improves in performance, and was able to eat more. Despite of short period of observation, this case indicates that Bojungikgi-tang gamibang treatment to the patient could work as hemostat, further improved quality of patient's life.

본 논문에서는 이동하는 광대역 음원의 위치추정에 적합한 높은 분해능을 가지는 광대역LPA (local polynomial approximation) 빔형성기법을 제안한다. 제안한 기법은 여러 개의 데이터 단편으로부터 구하는 공분산행렬 대신, 하나의 데이터 단편의 여러 개 주파수 성분으로부터 얻은 조향 공분산행렬을 이용하는 STMV(steered minimum variance) 기법을 LPA 빔형성기법에 적용하였다. STMV 기법의 센서가중벡터를 이용하여 LPA 가격함수를 구성하였으며 이를 최대화 시키는 방위각과 각속도를 2차원 탐색을 통하여 추정함으로써 높은 방위각 분해능을 가지도록 하였다. 모의신호와 실제 해상 실험 데이터를 이용하여 제안한 기법의 성능을 기존의 기법과 비교, 분석 하였다

Coalescence process of binary immiscible fluid mixtures having bimodal size distributions, prepared by mixing two pre-sheared samples at different shear rates, ${\gamma}_{pre1}\;and\;{\gamma}_{pre2}$, under shear flow at a final shear rate, ${\gamma}_f$, are examined by transient shear stress measurements and microscopic observations in comparison with the results for simply pre-sheared samples having narrow size distributions (unimodal distribution samples). Component fluids are a silicone oil (PDMS) and a hydrocarbon-formaldehyde resin (Genelite) and their viscosities are 14.1 and 21.0 $pa{\cdot}sec$ at room temperature $(ca.\;20^{\circ}C)$, respectively. The weight ratio of PDMS: Genelite was 7:3. Three cases, $({\gamma}_{pre1}=7.2sec^{-1},\;{\gamma}_{pre2}=12.0sec^{-1}\;and\;{\gamma}_f=2.4sec^{-1}),\;({\gamma}_{pre1}=0.8sec^{-1},\;{\gamma}_{pre2}=4.0sec^{-1}\;and\;{\gamma}_f=2.4sec^{-1}),\;and\;({\gamma}_{pre1}=7.2sec^{-1},\;{\gamma}_{pre2}=12.0^sec^{-1}\;and\;{\gamma}_f=7.2sec^{-1})$ the first case, transient shear stress did not show any significant difference but domains larger than the initial state are observed at short times. In the latter cases, there exist undershoot of shear stress, reflecting existence of deformed large domains, which is confirmed by the direct observation. It is concluded that coalescence between large and small domains more frequently occur than coalescence between the domains with similar size in the bimodal distribution samples.

Objectives: The purpose of this study was to observe the early postpartum low back pain and pelvic girdle pain in the Korean medical hospital for 2-weeks. Methods: Fifty-one postpartum women who admitted for postpartum care in Korean hospital from December 3rd, 2011 to January 31st, 2012 had written out pain measurement questionnaires(SF-MPQ, VAS, ODI) three times for 2-weeks. SPSS 18.0 for Windows was used to analyse the data and the independent samples t-test, paired T-test were used to verify the results. Results: 1. Evaluation of low back pain within the first week after birth was as follows: SF-MPQ sensory area was $5.06{\pm}4.41$ points; SF-MPQ emotional areas was $0.86{\pm}1.34$ points; VAS mean was $3.79{\pm}2.02$ points; and ODI mean was $10.27{\pm}6.69$. 2. Early postpartum low back pain and pelvic girdle pain were significantly decreased in SF-MPQ, VAS, and ODI after 2-weeks(p < 0.01). 3. Age, birth type, parity, weight, and BMI increased during pregnancy does not affect the postpartum low back pain and pelvic girdle pain. Conclusions: The top 10% of postpartum low back pain scale was 10.8 points or more in the sensory area of SF-MPQ, and 3 points or more in the affective area of SF-MPQ. In the case of VAS, it was more than 7 points, and ODI was more than 21.8 points. Postpartum back pain with oriental medical treatment was significantly improved.

This study investigates the impacts of land cover change due to urbanization on the Urban Heat Island Intensity (UHII) and the Heat Index (HI) over the Seoul metropolitan area using the Unified Model (UM) with the Met Office Reading Urban Surface Exchange Scheme (MORUSES) during the heat wave from 16, July to 5, August 2018. Two simulations are performed with the late 1980s land-use (EXP1980) and the late 2000s land-use (EXP2000). EXP2000 is verified using Automatic Weather Station (AWS) data from 85 points in the study area, and observation sites are classified into two categories according to the urban fraction change over 20 years; Category A is 0.2 or less increase, and Category B is 0.2 or more increase. The 1.5-m temperature and relative humidity in Category B increase by up to 1.1℃ and decreased by 7% at 1900 LST and 2000 LST, respectively. This means that the effect of the urban fraction changes is higher at night. UHII increases by up to 0.3℃ in Category A and 1.3℃ in Category B at 1900 LST. Analysis of the surface energy balance shows that the heat store for a short time during the daytime and release at nighttime with upward sensible heat flux. As a result of the HI, there is no significant difference between the two experiments during the daytime, but it increases 1.6℃ in category B during the nighttime (2200 LST). The results indicate that the urbanization increase both UHII, and HI, but the times of maximum difference between EXP1980 and EXP2000 are different.

본 연구는 서울에서 강한 강수와 관련된 대기연직구조를 객관적으로 분류하고 대표 종관장과 강수 특성을 제시하고자 하였다. 이를 위해 2009년부터 2018년까지 여름철 (6~8월) 서울에서 강한 강수(>15 mm hr^-1) 시 오산에서 비양된 레윈존데 자료에 객관적 방법을 적용하여 대기연직구조를 분류하였다. 그 결과 대기 전체가 습윤한 형태인 Thin Tube (TT) 형이 34.7% (17회), 건조한 하층 위로 습윤한 층이 존재하는 Inverted V (IV) 형이 20.4% (10회), 습윤한 하층 위로 건조한 공기가 침투하는 Loaded Gun (LG)이 20.4% (10회)로 분석되었다. TT형의 경우 SRH 값이 357.6 J kg^-1으로 역학적 불안정이 큰 반면, LG와 IV형의 경우 1000 hPa부터 600 hPa까지 열적 불안정이 큰 특징을 보였다. NCEP/FNL 자료를 사용한 합성장 분석에서 TT형의 경우 기압골 전면(500 hPa)인 서해상에 저기압이 위치하여(850 hPa) 저기압이 강화될 수 있는 종관 패턴이 형성되었다. IV와 LG형의 경우 북만주와 중국의 북동에 강한 저기압이 위치하는 종관 패턴을 보이며, 기압경도에 의한 남서기류의 유입이 상대적으로 약하였다. 강수 전반부에 강수가 집중되는 형태가 모든 유형에서 나타났으며, 특히 IV형의 경우 강수 전반 높은 강도로 강수가 집중되어 내린다. TT형의 경우 가장 많은 강수량(123.9 mm)을 보였지만 다른 유형과 비교하였을 때, 강수가 전·후반 고르게 오랜 시간 지속되는 특징을 보였다. 본 연구 결과는 서울에서 강수와 관련된 고층관측자료의 이해도를 높이는 동시에 강수 예보기술 발전에 기여할 수 있을 것이다.
