기후변화와 세계시장 개방에 따른 외래 및 돌발해충의 종류는 다양해지고 밀도는 지속적으로 증가하고 있지만 발생 실태에 관한 자료는 미흡하다. 본 연구는 경상지역 돌발 및 남방계 해충의 발생과 피해조사를 위해 미국선녀벌레, 갈색날개매미충, 꽃매미 등 돌발해충 6종을 경남 9시군과 경북 9시군에서 월동기 1회, 약충기 2회, 성충기 1회를 순회 조사하였고, 애멸구, 배추좀나방, 볼록총채벌레 등 남방계 해충 5종을 산간지, 중산간지, 평야지 각 3지역에서 10일 간격으로 조사하였다. 돌발해충인 꽃매미와 갈색날개매미충 월동난 발생현황으로 농경지 발생면적은 2017년 비해서 2018년도에 발생면적이 늘었으나 발생 농가수는 줄어들어 발생지역은 점차 확대해가고 있으나 발생밀도는 줄어드는 것으로 조사되었다. 해충별 조사결과로 미국 선녀벌레 약충이 함안에서 가장 밀도가 많이 조사되었고, 함양, 상주, 예천 둥에서 발생하였고, 갈색날개매미충 약충은 하동에서 가장 발생이 많았고 진주, 사천, 고성, 산청, 함양, 거창, 상주, 예천 등에서 넓게 발생하였으나 꽃매미 약충은 함안과 함양에서만 조사되었다. 고도별 발생 차이는 발생밀도가 적어서 알 수가 없었다. 갈색여치는 조사지역 모두에서 발생을 확인하지 못했고 먹노린재는 하동에서만 일부 조사되었고 나머지 지역에서는 확인하지 못했다. 목화진딧물은 조사지역간에 밀도 차이가 많았고 고도에 따른 차이보다는 농가에서 농작물 재배관리나 조사 시기에 따른 차이로 보인다. 애멸구의 월동기 조사와 육안조사 결과 발생밀도가 낮았고, 볼록총채벌레는 트랩조사 결과 조사지역 감나무에서 모두 발생하였으나 발생밀도는 높지 않았고 7월중 밀도가 함양에서 평균 9.8마리로 가장 높았다.

We measured cobalt content in sorghum (Sorghum bicolor (L.) Moench.) by atomic absorption spectrophotometry: their absorbance and back ground values. These analyses were with AA-680 of Shimadzu. The mode was BGC; wave length, 240.8 ㎚, 240.7 ㎚, 240.6 ㎚, respectively. The recommended wave length is 240.7 ㎚ for Co analysis. It was done through several ratios among 4 factors; mean of absorbance(AM), standard deviation of absorbance (AS), mean of background(BM), standard deviation of background.(BS). The result was t㏊t 240.6 ㎚ was the favourable. And t㏊t of 240.8 ㎚ was better t㏊n t㏊t of 240.7 ㎚ for the Co analysis.

국내 경수로원전 1차 냉각재와 중저준위 방사성폐기물 내 핵종방사능비에 대한 유관성을 검토하고자 특수하게 제작된 RCS sampling kit를 이용하여 원전 정상운전기간 동안 핵종을 포집하였다. 시료채취는 경수로형 전 원자력 발전소를 대상으로 2004년과 2005년에 걸쳐 시료를 채취하였고, 방사화학적 방법인 시료 전처리 및 핵종분리를 통하여 핵종 방사능을 분석하였다. RCS sampling kit 내 필터와 수지에서 분석된 핵종 방사능비는 각각 2.32-2와 7.3E-1을 보였으며, 동일주기 내 발생된 중 저준위 방사성폐기물인 농축폐액, 폐수지, 잡고체시료 내 핵종 방사능비는 각각 6.3E-1, 6.7E-1 및 5.7E-2로 시료유형 에 따라 1차 냉각재와 유사성을 갖는 것으로 확인하였다.

Background : Rehmannia glutinosa is a perennial herb belonging to the family Scrophulariaceae. Its roots have been utilized as a traditional medicine but the aerial parts (flower, flower stalk, leaf) were not used. In this paper, we aimed to determine the content of three compounds [aucubin, catalpol, and γ-aminobutyric acid (GABA)] in different organs of R. glutinosa. Methods and Results : The flower, flower stalk, leaf, and root of R. glutinosa were harvested in the end of August. The aucubin and catalpol were analyzed by LC/MS, whereas GABA was analyzed by GC/MS. The aucubin content was the highest in the leaf, while catalpol and GABA were the highest in the flower. The aucubin content of in the leaf was 1.43, 0.81, and 1.07 ㎎/g, respectively. The catalpol content of flower in Dakang, Tokang, and Suwon 9 was 41.06, 28.78 and 37.48 ㎎/g, respectively. The GABA content of flower in Dakang, Tokang, and Suwon 9 were 0.79, 0.76 and 0.65 ㎎/g, respectively. Conclusions : The contents of aucubin, catalpol, and GABA were higher in leaf and flower than that of root. This study provides the important information of R. glutinosa leaf and flower as a potential supplement.

Background : The Production of high quality ginseng seedling become increasingly important in the cultivation of ginseng because the quality of ginseng seedling is closely related to yield of ginseng. However, it has become difficult to produce high quality ginseng seedling due to environmental instability such as an increase in the occurrence of abnormal climate and pests, and the difficulty in obtain new place to cultivate ginseng seedling. This study was carried out to analyze the growth characteristics of ginseng seedling according to application of fermented compost during ginseng seedling cultivation Methods and Results : In order to evaluate the effect of fermented compost on the growth of ginseng seedling, fermented compost containing antagonistic microorganism was prepared and applied 300kg per 10a to planned place for ginseng cultivation. After seeding of the ginseng seeds, the growth of ginseng was analysed. The pH, EC, organic matter, P2O5 and NO3-N of the compost treated group were 6.1, 2.75 ds/m, 18.97 g/㎏, 1,202 ㎎/㎏ and 287.4 ㎎/㎏, respectively, while those of non-treated group were 6.6, 0.25 ds/m, 14.67 g/㎏, 1,055 ㎎/㎏ and 8.77 ㎎/㎏, respectively. As a result of analyzing the growth characteristics of ginseng seedling, the growth of aboveground part was not significantly different between the treated and non-treated group. The root length and root diameter were 13.0 ± 1.50 ㎝ and 5.5 ± 0.27 ㎜, respectively, which were not significantly different from non-treated group. However, root weight was 1.20 ± 0.14 g, which is 1.4 times higher than that of control. Conclusion : It was confirmed that the quality of ginseng seedling was improved by compost application. These results suggested that fermented compost could be used as a material for nutrients management in ginseng seedling cultivation.

Gelatinization characteristics of 111 glutinous rice varieties were evaluated by Rapid Visco Analyzer. Gelatinization viscosity of glutinous rice tested varied with ecotypes or varietal groups: indica, japonica, and Tongil type. Indica rice showed the highest average value of initial pasting temperature. The average values for peak, hot, and cool viscosities were highest in Tongil-type rice, and lowest in japonica rice. Japonica showed the lowest breakdown and consistency, but the highest setback value. Indica was lower in alkali digestion value (ADV), and shorter in gel length after gelatinization thanjaponica and Tongil-type. Glutinous rices tested could be divided into six groups by cluster analysis based on their gelatinization characteristics. Group I-A was mostly early maturing japonica varieties while I-B was mostly indica and Tongil-type rices. Groups II-A and II-B were consisted of very early maturingjaponica, and III-A and III-B included medium or medium late maturingjaponica varieties. Group III-A showed the lowest average values of peak, hot, cool, and consistency viscosities, and also in breakdown and setback ratios. Group I-B revealed the highest values in peak, hot, cool, breakdown, and consistency viscosities. ADV was low in groups I-A, I-B, and II-B, and gel consistency was not different among the six varietal groups. Principal component analysis using seven traits related with gelatinization produced four effective components, and the first and second components were highly correlated with all the gelatinization characters evaluated
