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.

The objectives of this study were to investigate the effects of thoracic flexibility exercise on chest function and mobility and to provide the information of physical therapy for patients with idiopathic scoliosis. Forty female subjects who were diagnosed with scoliosis participated in this study and were divided into the experimental and control groups. The experimental group consisted of 20 patients who were treated with thoracic flexibility exercise program during the admission (10 days) and one month after discharge. The control group consisted of 20 patients who were not treated with thoracic flexibility exercise program. Vital capacity was measured using a respirometer. The chest expansion were calculated using differences of chest circumference between maximum inspiration and maximum expiration measured under armpits, at the junction between the sternum and xyphoid process, and at the waist. All subjects were measured two times: before the admission and at one month after discharge. Data were compared by groups using independent t-test. Vital capacity and chest expansion values (the armpit, chest and waist values) were significantly higher for the experimental group compared to those of the control group (p<.05). The findings of this study show that thoracic flexibility exercise program can lead to an increase in vital capacity and chest expansion and has a positive effects in relieving symptoms and restoring thoracic mobility.

IEEE 802.22에서는 사용하지 않는 TV 대역을 찾아 고정 사용자에게 고속 패킷 전송을 제공하는 WRAN 시스템을 논의하고 있다. 본 논문에서는 WRAN 시스템을 위해 단일 프리앰블을 이용한 시간 및 주파수 동기 알고리즘을 제안하고 WRAN에서 고려하는 무선 채널 모형에서 성능을 살펴본다. 제안한 알고리즘은 기존의 시간 동기 메트릭을 간단히 수정하여 시간 동기를 좀 더 안정적으로 찾을 수 있도록 함으로써, 시간동기후에 수행되는 주파수 옵셋 추정기의 성능을 향상시킨다.

Stepped beam with immovable ends for large amplitude of vibration including effects of both longitudinal displacement and inertia is investigated for free and forced vibration using finite element method. Modified harmonic force matrix is introduced for analysis of vibration with finite amplitude of the stepped beam under uniform harmonic loading and beam with nonuniform harmonic loading. Numerical examples of stepped beam with various support conditions are analysed for deflections and natural frequencies. Results show that the proposed method is valid and efficient.

It were studied the effects of ammonium sulfate as additive, calcination temperature and amount of sulfuric acid for extraction of alumina from Sancheong white kaolin by wet acid process. DTA and XRD indicated that mixtures were decomposed completely at 550℃. Optimum condition for extraction of alumina were as follows. 1. 0.2-0.3 mole of ammonium sulfate to 1 mole of Al₂O₃in kaolin was suitable. 2. calcination temperature was 550℃. 3. 1%, 100cc of H₂SO₄was adaptable to l gr of kaolin. 4. Both α-and γ-Al₂O₃were obtainable. 5. Low-iron kaolin was adaptable to reduce contamination of Alumina from iron.

저자들은 비호지킨씨 림프종 환자에서 항암 치료 후 질환의 진행성 병변과 감별을 요했던 우폐 중엽의 단발성 종괴를 흉강경하 생검으로 폐 효모균증을 확진하고 amphotericin B와 fluconazole로 치료한 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Non-Hodgkin's lymphoma is monoclonal expansion of malignant B or T cells. The immunocompromised status in this disease is accompanied by many infections. The cryptococcosis, caused by Cryptococcus neoformans, frequently occurs in leukemia, Hodgkin's disease, sarcoidosis, diabetes mellitus, tuberculosis, and long-term steroid-using patients. Recent increasing incidence of fungal infection could be due to the spread of AIDS and transplantation. We experienced one patient with lung mass in Non-Hodgkin's lymphoma after three cycles of chemotherapy, which could not be discriminated from the newly developed lymphoma mass. Cryptococcus neoformans was isolated from the lung tissue obtained by thoracoscopic biopsy. Herein we report this case with brief review of pertinent literature.

김성원,심재옥,김언곤 한밭대학교 산업과학기술연구소 2001 논문집 Vol.5 No.-

In this paper, we have simulated the performance of BPSK/OFDM system with 1/2 convolution coding under AWGN(Additive White Gaussian Noise) Rummler fading channel. The system adapted (2,1,7) convolution encoder as channel coding method, OFDM with subcarrier 64 as modulation technique, and BPSK as mapping method. In the Rummler fading channel, delay time is set 1, original signal is decremented during direct-path signal passing through multipath as factor of this, we changed to value of attenuation of the multipath component.(0.3, 0.6 and 0.9) Then we looked at coding effect of channel coding and decoding method. As a result of simulation, when multipath component is 0.3, 0.6 and 0.9 in the BER=10^-3, we obtained the results that the coding effect of this system is about each 3㏈, 4㏈, and 9㏈ through the coding methods. And then by using soft decision as decoding we method obtained the better performance of each about 2㏈, 3㏈, and 5.5㏈ than hard decision. Also, when BER is 10^-5, we obtained the results that the coding effect of this system are each about 5㏈, 5.5㏈, 10㏈ through the coding methods. And then by using soft decision as decoding method obtained the better performance of each 2.5㏈, 3.5㏈ and 6.5㏈ than hard decision.
