본 연구는 부존 조사료자원의 이용을 활성화하여 수입사료를 줄이고 가축 사료비를 절감하고자 2010년도에 경기 파주 (민통선 지역)와 경기 안산 (시화지구)에서 갈대와 억새 등 야초자생지를 탐색하고, 수확?이용실태 조사와 함께 사료가치를 분석하였다. 파주 민통선 내억새 (Miscanthus sinensis)와 갈대 (Phragmites communis) 혼합 자생지는 90~100 ㏊ 규모로, 1차 곤포작업으로 사일리지 520톤 (㏊당 6톤), 2차로 380톤 (㏊당 4톤)을 조제하여, 연 사일리지 900톤 (㏊당 10톤)을 생산하였다. 곤포의 유통가격은 롤당 52~55천 원으로 ㎏당 130~137.5원이었다. 곤포는 자가소비 50~70%, 판매유통 30~50%로, 수익성은 인건비 정도로 추정되었다. 초장 70 ㎝의 재생 억새는 조단백질 9.6%, 상대사료가치 82.4 (건초 4등급), 건물 소화율 67.7%, 초장 70 ㎝의 재생 갈대는 각각 13.8%, 84.3 (4등급), 67.9%로 사료가치는 높았으며, 수확이 늦어짐에 따라 사료가치는 크게 낮아졌다. 안산 시화지구 (3공구)의 갈대 등 야초류자생지는 100 ㏊ 정도로 2009년도에는 50 ㏊에서 사일리지 550톤 (㏊당 11톤)을 생산하여 롤당 50천 원에 유통하였으며, 2010년도는 잦은 강우와 장마로 부분 이용에 그쳤다. 고초기의 갈대는 건물률 89.8%, 조단백질 2.2%, NDF 80.6%, ADF 55.4%, 상대사료가치 52.9 (5등급), 건물 소화율 36.4%로 볏짚에 비해서도 사료가치는 크게 낮았다. 초장 80 ㎝의 재생 갈대는 조단백질 12.9%, 상대사료가치 99.8 (3등급), 건물 소화율 66.6%로 사료가치는 양호하였으며, 개화기의 초장 150 ㎝ 갈대는 조단백질 4.5%, 상대사료가치 59.9 (5등급), 건물 소화율 42.2%로 볏짚의 사료가치와 비슷하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거?이용하되, 사료가치를 유지하고 가축 기호성을 고려한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전 (늦어도 7월까지)에 수확?이용하는 것이 권장된다. 본 연구에서 조사된 대부분의 야초류는 상대사료가치가 75 이하인 건초 5등급으로 사료가치는 매우 낮았으며, 키가 작은 영양생장기에 수확한 경우에만 4등급으로 나타났다. 부존 조사료자원의 이용은 양질의 사료작물 생산과 병행하여 추진하는 것이 바람직하였다. This study was carried out in 2010 to investigate the utilization and nutritive value of native grasses, such as Phragmites communis and Miscanthus sinensis which might reduce the cost of feeding domestic cattle. The regions within the Civilian Control Line in Paju and Sihwa region in Ansan were surveyed. In Paju, the yearly silage production was 900 MT harvested from 90 ha (10 MT/㏊). About 30~50% of these were sold out at the marketing price of 52,000~55,000 Won per roll (130~137.5 Won/㎏). Regrown Miscanthus sinensis of 70 ㎝ in length contained 9.6% of crude protein (CP), 82.4 of relative feed value (RFV), and 67.7% of in vitro dry matter digestibility (IVDMD). Regrown Phragmites communis of 70 ㎝ in length contained 13.8% of CP, 84.3 of RFV, and 67.9% of IVDMD. As harvesting was delayed, the quality was decreased dramatically. In Ansan region, Phragmites communis plantation covers 100 ha. The silage production was 550 MT from the area of 50 ha (11 MT/㏊) in 2009. And the marketing price was 50,000 Won per roll. But in 2010 only a small amount of grasses could have been baled due to frequent and much rainfall from spring to summer season. However, the good forage quality was observed from regrown Phragmites communis of 80 ㎝ in length, 12.9% CP, 99.8 RFV and 66.6% IVDMD, while that of late matured grasses was very low, 2.2% CP, 52.9 RFV and 36.4% IVDMD, greatly lower than forage quality of rice straw. The quality of grasses at bloom stage of 150 ㎝ in length was similar to that of rice straw, showing 4.5% CP, 59.9 RFV and 42.2% IVDMD. In conclusion, the overall quality of most native grasses in this survey were very poor. Therefore, we recommend that Phragmites communis and Miscanthus sinensis should be harvested during June or July to obtain better forage quality which is richer in forage values than rice straw. Production of high quality forage crops was also desirable for self sufficiency of forage.

Weight-in-Motion-Based Ambient Truck Characteristic Identification in Highway Bridges

Seo, Jun Won,Hu, Jong Wan Trans Tech Publications 2014 Advanced materials research Vol.1025 No.-

<P>Ambient truck classification and weight data have been used in numerous transportation applications, focusing on highway safety. Specifically, ambient truck characteristics identified from Weight-In-Motion (WIM) data obtained from vehicle weigh stations have been considered to be likely candidates to better understand structural response of highway bridges to live-load events. This paper provides a framework to explicitly identify WIM-based ambient truck characteristics specific to highway bridges of interest. As an application of the framework, a highway steel I-girder bridge in the United States was selected and a network of strain sensors was installed on the bridge deck. Multiple strain time history data sets resulting from ambient trucks were measured and evaluated via a structural health monitoring (SHM) system with strain sensors. Each set of strain data representing a single truck, which cross the bridge, was used to identify its features, such as axle numbers and spacings. WIM trucks specific to each set were also characterized by examining the monitored strain time history patterns. These patterns make it possible to the identification of ambient WIM truck configurations. WIM data were obtained from weigh stations located adjacent the bridge. It is anticipated that this work will result in the creation of ambient truck pools on a specific bridge. Their pools will be used as live load inputs in the bridge model to investigate the structural behavior and to evaluate the bridge health conditions..</P>

Aims: Many patients were died after deceased donor liver transplantation (DDLT) because of poor nutritional status by end-stage liver disease. Purpose of present study is to compare the mortality in the period without nutritional support (NST) and that in the period with NST. Methods: Forty-six patient underwent DDLT in Samsung Medical Center at the 2016. All recipients routinely underwent enteral feeding after liver transplantation. NST consist of transplant surgeon, hepatologist, rehabilitation doctor, dietitian, pharmacist, and nurse. NST has cared for twenty-one patients after September 2016. Results: There were no statistically significant differences in baseline and perioperative characteristics between the two groups. The median MELD scores are 36 (range, 21-40) in the period without NST group and 36 (range, 23-40) in the period with NST group, respectively (P=0.596). The incidence of in-hospital mortality in the period without NST group was 24.0% (6/25), but that in the period of NST group was 4.8% (1/20), respectively. In-hospital mortality in the period with NST group was lower than that in the period without NST group, but there was no statistically significant between the groups (P=0.070). Conclusions: Present study suggests that NST approach in the DDLT patients with high MELD score should be required for preventing in-hospital mortality.

Seo, Chang-Seob,Lee, Won-Hee,Chung, Hee-Wook,Chang, Eun Ju,Lee, Seung Ho,Jahng, Yurngdong,Hwang, Bang Yeon,Son, Jong-Keun,Han, Sang-Bae,Kim, Youngsoo John Wiley Sons, Ltd. 2009 Phytotherapy research Vol.23 No.11

<P>Hyperpigmentation disorders such as freckles and senile lentigines in the skin are associated with abnormal accumulation of melanin pigments. In this study, two lignan constituents were isolated from Saururus chinensis Baill (Saururaceae) as inhibitors of cellular melanin production by bioassay-guided fractionations. The active constituents were manassantin A and B that dose-dependently inhibited melanin production in α-melanocyte stimulating hormone (α-MSH)-activated melanoma B16 cells with IC<SUB>50</SUB> values of 13 nm and 8 nm, respectively. Arbutin as a positive control exhibited an IC<SUB>50</SUB> value of 96 µm on α-MSH-induced melanin production. Further, manassantin A inhibited forskolin- or 3-isobutyl-1-methylxanthine (IBMX)-induced melanin production with IC<SUB>50</SUB> values of 14 nm or 12 nm, respectively. Manassantin A decreased cellular amounts of IBMX-inducible tyrosinase protein but could not affect the catalytic activity of cell-free tyrosinase, a key enzyme in the biosynthetic pathway of melanin pigments. Finally, this study could provide a pharmacological potential of S. chinensis in hyperpigmentation disorders. Copyright © 2009 John Wiley & Sons, Ltd.</P>

SEO, EUNKYOUNG,YOON, YOHAN,KIM, KYEONGYEOL,SHIM, WON-BO,KUZMINA, NINA,OH, KEUM-SOON,LEE, JONG-OK,KIM, DONG-SUL,SUH, JUNGHYUCK,LEE, SOO-HYUNG,CHUNG, KEE-HEY,CHUNG, DUCK-HWA International Association for Food Protection 2009 Journal of food protection Vol.72 No.2

<P>To survey fumonisins B1 (FB1) and B2 (FB2) in agricultural products consumed in South Korea and provide an exposure assessment, ground samples were extracted (80% MeOH), filtered (0.2 μm), and cleaned up. After evaporation, dry residues were reconstituted in 50% MeOH, and a 50-μl aliquot of this sample was mixed with 200 μl of o-phthaldialdehyde for derivatization. The derivatives were analyzed with a high-performance liquid chromatography system equipped with a fluorescence detector. For validation of the detection procedure, linearity, accuracy, precision, detection limit, and quantification limit were determined. The validated detection method was then used to survey fumonisins in white rice, brown rice, barley, barley tea, beer, wheat flour, millet, dried corn, corn flour, corn tea, canned corn, popcorn, and breakfast cereal. Retention times for FB1 and FB2 standards were 7 and 18 min, respectively. Linearity (R2 = 0.99995 to 0.99998), accuracy (81.47 to 108.83%), precision (2.35 to 5.77), detection limit (25 ng/g or ng/ml), and quantification limit (37 ng/g or ng/ml) indicated that this procedure is capable of quantifying fumonisins in agricultural products. Only FB1-positive samples (5.12%, three dried corn samples and five corn flour samples) were found at 90.89 to 439.67 ng/g. According the survey results, an estimated daily intake of FB1 and FB2 in Korea was 0.087 ng/kg of body weight per day. These results indicate that continuous monitoring of these mycotoxins is necessary to establish appropriate risk assessment, and the maximum tolerable daily intake of fumonisins in Korea is lower than the 2 μg/kg set by the Joint Food and Agriculture Organization-World Health Organization Expert Committee.</P>

Won-Joon Choi,Byoung-Moo Min,Byung-Hyun Shon,Jong-Beom Seo,오광중 한국공업화학회 2009 Journal of Industrial and Engineering Chemistry Vol.15 No.5

To examine the characteristics of absorption and regeneration, the simultaneous removal efficiency of carbon dioxide/sulfur dioxide (CO2/SO2), the CO2 absorption amount, and the CO2 loading value of an ammonia (NH3) solution added to 2-amino-2-methyl-1-propanol (AMP) were investigated using the continuous absorption and regeneration process. The performances of this system, such as the removal efficiency of CO2 and SO2, absorption amount, and CO2 loading, were evaluated under various operating conditions. Based on the experimental study, the optimum conditions were a liquid circulation rate of 90 mL/min and gas flow rate of 7.5 L/min. The addition of NH3 into aqueous AMP solution increased the absorption rate and loading ratio of CO2 and raised the removal efficiencies of CO2 and SO2 to over 90% and over 98%, respectively.
