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.

Effects of Strain Rate and Temperature on Fracture Strength of Ceramic/Metal Joint Brazed with Ti-Ag-Cu Alloy

Seo, Do-Won,Lim, Jae-Kyoo The Korean Society of Mechanical Engineers 2002 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.16 No.9

Ceramics are significantly used in many industrial applications due to their excellent mechanical and thermal properties such as high temperature strength, low density, high hardness, low thermal expansion, and good corrosion resistive properties, while their disadvantages are brittleness, poor formability and high manufacturing cost. To combine advantages of ceramics with those of metals, they are often used together as one composite component, which necessiates reliable joining methods between metal and ceramic. Direct brazing using an active filler metal has been found to be a reliable and simple technique, producing strong and reliable joints. In this study, the fracture characteristics of Si$_3$N$_4$ ceramic joined to ANSI 304L stainless steel with a Ti-Ag-Cu filler and a Cu (0.25-0.3 mm) interlayer are investigated as a function of strain rate and temperature. In order to evaluate a local strain a couple of strain gages are pasted at the ceramic and metal sides near joint interface. As a result the 4-point bending strength and the deflection of interlayer increased at room temperature with increasing strain rate. However bending strength decreased with temperature while deflection of interlayer was almost same. The fracture shapes were classified into three groups ; cracks grow into the metal-brazing filler line, the ceramic-brazing filler line or the ceramic inside.

One of the largest and fastest growing segments of the tourism industry, sport tourism refers to travel to play sports, watch sports, or to visit a sport attraction including both competitive and non-competitive activities. In this respect, cycling can be considered as not only a form of physical exercise but also a form of tourism in which cycling is a usual tourism-related activity, heading to a particular destination. The purpose of this study is to examine how demographical differences of cycle tourists are related to the quality of their life. An online survey was conducted and data was analyzed using frequency, reliability, and one - way ANOVA using SPSS 22.0. First, we found that there was no significant difference on the quality of physical life based on demographical characteristics. Second, the analysis of the relationship between demographical characteristics and the quality of mental life showed that income level affects their quality of mental life. Third, the analysis of the relationship between socio demographic characteristics and the quality of social life showed that marital status affects the quality of social life. Fourth, no statistically significant difference was found between the demographical characteristics and the quality of environmental life. Further implications were discussed.

Follow-up Study of Peripheral Blood Carcinoembryonic Antigen mRNA Using Reverse Transcription–Polymerase Chain Reaction as an Early Marker of Clinical Recurrence in Patients With Curatively Resected Gastric Cancer

Seo, Jae Hong,Choi, Chul Won,Kim, Byung Soo,Shin, Sang Won,Kim, Yeul Hong,Kim, Jae Sun,Lee, Sang Woo,Choi, Jae Hyun,Park, Yung Tae,Mok, Young Jae,Kim, Chong Suk,Kim, Jun Suk Lippincott Williams Wilkins, Inc. 2005 American journal of clinical oncology: cancer clin Vol.28 No.1

In this study, we evaluated the clinical significance of detecting carcinoembryonic antigen (CEA) mRNA in the peripheral blood samples of patients with gastric cancer. We analyzed the peripheral blood of 46 patients with gastric cancer who had undergone curative resection. The presence of CEA mRNA was serially monitored using a CEA-specific reverse transcription–polymerase chain reaction (RT-PCR) every 2 months. The clinical recurrence rates according to category were as follows: 100% (3 of 3) in the positive conversion, 0% (0 of 18) in the negative conversion, 50% (3 of 6) in the always-positive, and 10.5% (2 of 19) in the always-negative category. The recurrence rate was 66.7% (6 of 9) in the positive group and 5.4% (2 of 37) in the negative group (P ≤0.00022). Multiple logistic regression analysis demonstrated that only group variable had a significant effect on clinical recurrence (P = 0.015). We conclude that RT-PCR analysis of CEA mRNA in the peripheral blood seems to be a promising tool for the early detection of micrometastatic circulating tumor cells in gastric carcinoma patients and that it can be useful used to identify patients at risk for recurring.
