Background:The purpose of improving the quality of oriental medicinal herbs is to contribute to the improvement of the income of farm. The present study investigated the effect of reasonable drying methods, different storage conditions and packageing materials on quality and stability of Scutellaria baicalensis Georgi and for developing GAP (good agricultural practice) guide book.Methods and Results:Three methods of drying Scutellaria baicalensis roots produced over two years were used to estimate loss rate owing to drying, storage, and packaging. The methods of drying were categorized into natural drying (36 - 60 h by sunshine), drying with heat dryer (2 - 10 h), or drying with gas bulk dryer (2 - 10 h). After cleaning, and initial drying for a few days under controlled temperature conditions, the second phase of drying was carried out at 35, 45 and 55°C. Changes in hunter color values and quality under the two studied storage treatments (at 20°C indoors and at 4°C in a refigerator) were evaluated. Storage period for 60, 120, and 180 days in three packaging materials, PE (polyethylene package), PP (polypropylene gunnysack), and WP (watertight packing paper) were studied.Conclusions:Initial cleaning, reasonable gas drying and hot air drying, and drying in an oven at 35 and 45°C after cutting the roots resulted in the lowest loss rates in S. Baicalensis root. Hunter color valuse indicated that stroage of dry roots at room temperature was better than PP packaging, and that cold stroage was better than PE packaging for long-term stability.

우리나라는 생활수준 향상과 에너지 소비의 증가로 인해 범세계적으로 에너지 수요가 급격히 증가 되었으며 과거 국내에 설치된 폐기물처리시설의 경우 폐기물의 성상 불균형 현상과 낮은 발열량으로 인해 에너지 생산 및 활용 부분을 고려할 수 없었으나 현재 폐기물에 대한 인식변화와 체계적인 분리수거체계로 인하여 고발열량의 연료 확보가 가능하다. 폐기물처리 기술 중 하나인 소각처리 기술은 쓰레기 발전 등의 여열 이용을 충실히 하는 것에 의해 화석연료 사용량 감소를 실현 가능하며 2013년 ‘자원순환사회촉진법에 관한 법률’ 의 개정으로 폐기물은 바이오매스 연료발전으로 자리매김 되고 있다. 신재생에너지의 중요성이 대두되면서 폐자원에너지화를 위한 가연성 폐기물 고형연료화, 소각폐열 회수로 인하여 지역난방이나 전력생산 등에 많은 투자가 이루어지고 있다. 본 연구에서는 국내 소각시설의 효율적 폐열회수를 위한 조건을 도출하고자 국내･외 소각시설의 폐열회수 및 전력생산에 대한 사례 조사를 토대로 국내에서 현재 설치되어 있는 공공자원회수시설 및 민간 고형연료 시설 중 모범적으로 운영 중인 사례를 찾아 온도 및 압력 범위를 조사하여 이를 기초로 소각폐열 발전량에 따른 실제 스팀생산 가능성을 확인할 수 있었으며 온도 및 압력 변화에 따른 모델링을 통하여 효율 향상을 위한 최적 설계의 근거치를 산출 제시할 수 있었다. 본 연구결과는 향후 국내 소각처리 시설 운영 비용절감 및 에너지 회수율 향상을 위한 최적 설계에 필요한 방법론 도출과 데이터 산출의 기초자료로 활용될 수 있을 것이다.

농촌진흥청 국립식량과학원에서는 용도별 품종의 다양화를 위해 답리작 적응 과자용 밀 품종 ‘고소’를 개발하였다. 고소밀은 1998년도에 연질인 고분밀을 모본으로 하고, 숙기가 빠른 올밀을 부본으로 인공교배하여 SW98148 조합을 육성하였다. 경기도 연천에서 집단재배 후 계통을 전개하여 초형과 수형이 양호하며 내한성이 강한 계통인 SW98148-YB-9-2-4-1-3-1을 2006년부터 2개년간 생산력 검정을 거쳐 ‘익산 320호’로 계통명을 부여하였다. 그 후 2008년부터 3개년 동안 지역적응시험을 실시한 결과 숙기가 빠르며 수량성이 높고, 과자적성이 우수하여 2010년 농작물 직무육성 신품종심의회에서 ‘고소’로 명명하였다. 고소밀의 파성은 Ⅱ형으로 춘파형이고, 엽색은 녹색이며 이삭은 방추형이고, 종자는 중간 크기로 적색이다. 출수기와 성숙기는 밭상태 조건에서 각각 4월 28일과 6월 7일, 논상태에서는 각각 4월 25일과 6월 4일로 비슷하다. 고소밀의 리터중(799 g/L)과 천립중(42.5 g) 은 금강밀(804 g/L과 46.7 g)보다 낮고, 내한성(4.4%)과 수발아(4.0%) 저항성이 강하고, 내도복성이 높다. 고소밀의 제분율(63.77%), 단백질(9.8%), 침전가(30.0 ml)과 글루텐(7.2%) 함량은 금강밀(73.6%, 12.6%, 50.0 ml과 10.8%)보다 낮고, 과자적성이 우수하였다. ‘고소밀’의 HMW-GS 조성은 Glu-A1에서 2*, Glu-B1에서 7+8을 나타내 금강밀과 조성이 같았으나, Glu-D1에서 2.2+12가 발현되었다.

This study was performed to investigate the adequate standard pot and number of plants per tree of raising seeding pot on the foxtail millet transplanting culture in the southern province. Due to the various application of wellbeinghealth food recently, for upbringing of the foxtail millet, millet and sorghum in minor cereals, R & D and policy support is being promoted actively. The foxtail millet growing season is so short from 90 to 130 days, and it is large variations for a growth temperature. The main results are as follows. When it comes to foxtail millet transplantation, seedling quality of 406 holes, 200 holes and 162 holes of raising seeding pot type were not all significant, and field rooting percentage is accounted for all 94 to 95%. Yield of a foxtail millet was exposed in 406holes 305 kg/10a>162holes 303 kg> 200holes 302 kg order, and it was no significance between test processing. When it's the raising seeding transplanting culture, in case of pot culture, 406holes pot culture were reduced the bed soil cost 63%, pot 50%, working hours 18% for 200holes pot. Transplanting seedling quality per a foxtail millet transplanting culture method, dry weight was high inclination as transplanting number of plant is less, and field rooting percentage displayed more than all 95%. Yield appeared to 2 plants seedling transplanting 315kg/10a> 3 plants seedling transplanting 304kg>1 plant seedling transplanting 256kg order. The projected cost per the pot-sort on the raising seeding transplanting culture of foxtail millet, the seedling transplanting culture of 406holes was reduced 40% percentages compared to 200holes as 76,230won/10a. As a result, 406holes pot and 2plants seedling transplanting culture, labor-saving culture was possible.

In this study, pressure drop was measured in the pulse jet bag filter without venturi on which 16 numbers of filter bags (Ø140 × 850 ℓ) are installed according to operation condition(filtration velocity, inlet dust concentration, pulse pressure, and pulse interval) using coke dust from steel mill. The obtained 180 pressure drop test data were used to predict pressure drop with multiple regression model so that pressure drop data can be used for effective operation condition and as basic data for economical design. The prediction results showed that when filtration velocity was increased by 1%, pressure drop was increased by 2.2% which indicated that filtration velocity among operation condition was attributed on the pressure drop the most. Pressure was dropped by 1.53% when pulse pressure was increased by 1% which also confirmed that pulse pressure was the major factor affecting on the pressure drop next to filtration velocity. Meanwhile, pressure drops were found increased by 0.3% and 0.37%, respectively when inlet dust concentration and pulse interval were increased by 1% implying that the effects of inlet dust concentration and pulse interval were less as compared with those changes of filtration velocity and pulse pressure. Therefore, the larger effect on the pressure drop the pulse jet bag filter was found in the order of filtration velocity(Vf), pulse pressure(Pp), inlet dust concentration(Ci), pulse interval(Pi). Also, the prediction result of filtration velocity, inlet dust concentration, pulse pressure, and pulse interval which showed the largest effect on the pressure drop indicated that stable operation can be executed with filtration velocity less than 1.5 m/min and inlet dust concentration less than 4 g/m3. However, it was regarded that pulse pressure and pulse interval need to be adjusted when inlet dust concentration is higher than 4 g/m3. When filtration velocity and pulse pressure were examined, operation was possible regardless of changes in pulse pressure if filtration velocity was at 1.5 m/min. If filtration velocity was increased to 2 m/min. operation would be possible only when pulse pressure was set at higher than 5.8 kgf/cm2. Also, the prediction result of pressure drop with filtration velocity and pulse interval showed that operation with pulse interval less than 50 sec. should be carried out under filtration velocity at 1.5 m/min. While, pulse interval should be set at lower than 11 sec. if filtration velocity was set at 2 m/min. Under the conditions of filtration velocity lower than 1 m/min and high pulse pressure higher than 7 kgf/cm2, though pressure drop would be less, in this case, economic feasibility would be low due to increased in installation and operation cost since scale of dust collection equipment becomes larger and life of filtration bag becomes shortened due to high pulse pressure.

The purpose of this study was to establish the optimal growth temperature and to select genetic resources for production of cowpea sprouts. Seowon was treated between 15°C and 30°C at intervals of 3°C to investigate growth temperature. Twelve resources, including Seowon, IT154149, IT154153, Tvu7426, and Tvu7778, were used for cultivating sprouts at a temperature of 27°C. The yield ratio of cowpea sprouts was highest at 27°C (657%), and was reduced when growth temperature was decreased. The hard seed rate was lower when the growth temperature was increased. Vitamin C content was highest at 24°C (2.85 mg/g), ranged between 2.15 and 2.29 mg/g at other growth temperatures, and increased with the length of the growth period. The inorganic component content of cowpea sprouts did not vary based on growth temperature, while the amino acid content increased with increasing growth temperature between 15°C and 24°C, and then subsequently decreased as growth temperature rose from 24°C to 30°C. IT154153 had the highest yield ratio of cowpea sprouts per genetic resource (647%), followed by Seowon (615%), and Tvu7426 (608%). Genetic resources with a higher yield ratio had smaller seeds, a thinner seed coat, and superior germinability. The inorganic components found at highest concentrations in the cowpea sprouts were potassium, magnesium, calcium, sodium, iron, molybdenum, and zinc (in that order). In comparison to raw seeds, the protein, calcium, zinc, molybdenum, and iron content in the cowpea sprouts was higher, while the content of aluminum and boron was lower.
