상추는 수요가 연중 지속됨에 따라 재배면적과 생산량이 증가하고 있는데, 주로 생식으로 이용되며 수확간격 이 짧아 해충 다발생시 약제방제가 어려운 작물이다. 최근 검은무늬밤나방이 약제방제가 소홀한 포장에서 잎을 광포식하여 빠른 시간내에 직접적인 피해를 주고 있다. 본 연구에서는 검은무늬밤나방의 온도별 발육특성을 구명하여 방제를 위한 기초자료로 이용하고자 한다. 검은무늬밤나방은 시설재배 상추에 발생한 유충을 채집하 여 실내 사육 후 항온조건(15, 20, 25, 30℃)에서 발육단계별 발육기간을 조사하였다. 온도가 높아짐에 따라 각 태별 발육기간은 짧아지는 경향이었으며, 유충은 보통 4회 탈피하였다. 25℃에서 알기간은 2.5일, 유충기간 10.0 일, 전용기간 1.0일, 번데기기간 7.0일로 알에서 성충까지의 발육기간은 20.5일 이었다.

최근들어 평균 온도가 평년보다 높게 경과함에 따라 노지 작물에 발생이 많은 파밤나방, 담배거세미나방, 담배 나방의 발생소장을 2023년 전북 익산의 노지 고추포장에서 성페로몬트랩을 이용하여 조사하였다. 파밤나방은 4월 중순부터 채집되기 시작하였으나 채집량은 적었고 6월 중순, 7월 중순, 9월 상순, 9월 하순에 발생최성기를 보였다. 담배거세미나방은 5월 중순부터 채집되기 시작하여 6월 상순, 7월 상순, 8월 상순, 9월 상순, 11월 상순에 발생최성기를 보였으며 8월 하순이후 발생량이 많은 경향이었다. 담배나방은 5월 상순부터 발생하기 시작하여 6월 중순, 8월 상순, 9월 상순에 발생최성기를 보였으며 10월부터는 채집량이 적은 경향이었다.

This study is intended to examine the motor skill learning and treadmill exercise on motor performance and synaptic plasticity in the cerebellar injured rats by harmaline. Experiment groups were divided into four groups and assigned 15 rats to each group. GroupⅠ was a normal control group(induced by saline); GroupⅡ was a experimental control group(cerebellar injured by harmaline); GroupⅢ was a group of motor skill learning after cerebellar injured by harmaline; GroupⅣ was a group of treadmill exercise after cerebellar injured by harmaline. In motor performance test, the outcome of groupⅡ was significantly lower than the groupⅢ, Ⅳ(especially groupⅢ)(p<.001). In histological finding, the experimental groups were destroy of dendrities and nucleus of cerebellar neurons. GroupⅢ, Ⅳ were decreased in degeneration of cerebellar neurons(especially groupⅢ). In immunohistochemistric response of synaptophysin in cerebellar cortex, experimental groups were decreased than groupⅠ. GroupⅢ's expression of synaptophysin was more increased than groupⅡ, Ⅳ. In electron microscopy finding, the experimental groups were degenerated of Purkinje cell. These result suggest that improved motor performance by motor skill learning after harmaline induced is associated with dynamically altered expression of synaptophysin in cerebellar cortex and that is related with synaptic plasticity.

Background : The effect of ridge-up bed cultivation and stem training method on the plant growth and yield of Cynanachum willfordii was investigated. Methods and Results : Domestic variety of Cynanachum willfordii was tested at Chungbuk ARES under the following conditions. Nonsupporting (custom) and I-form supporting was used for stem training method, and ridge height was set as 30 (custom) and 60 cm (high ridge). Planting spacing was adjusted to 30 (interrow spacing) × 20 cm (intrarow spacing), and other major management was followed the method of standard cultivation for medicinal crop. Investigated result from leaf characteristics, leaf length was longer in high ridge cultivation (HRC) as 11.1 cm than custom cultivation (CC) as 10.6 cm. Leaf width is proved to be 12.8 (HRC) > 11.2 cm (CC). Leaf number is proved to be 294 (HRC) > 254/plant (CC), with higher number of 44/plant at HRC and weight/10 leaves were more heavy at HRC (4.9 g) than that of CC (2.6 g). It was more fruit setting at HRC over 15/plant. According to the stem training method and ridge height from nonsupporting cultivation, main root was 4.0 (CC), higher than that of HRC over 0.5/plant. However, root length was more longer in HRC (28.6) than that of CC (25.0 cm). Main root diameter was also showed more thicker pattern in HRC. From staking cultivation, root number of HRC was 7/plant, it was recorded more 3/plant than that of CC, and it was also same pattern in main root length and root diameter. By the standard of commercial root, yield of living roots in nonsupporting cultivation were 59.0g/plant (HRC), it was more heavy over 10.4g/plant than that of CC. In staking cultivation, HRC were recorded as 74.2g/plant, more heavy 6.9g/plant than that of CC. Yield from I-form support stem training and ridge-up bed cultivation of HRC was higher approxmiately 52.7% than that of CC. Conclusion : Overall growth by high ridge cultivation of I-form support was good and yield of HRC was also increased over 52.7% than that of CC.

May-Thurner syndrome is caused by blockade of local venous flow due to local vascular intimal proliferation, caused by repeated pulsatile compression of the iliac or iliofemoral vein between the iliac artery and the lumbar spine. In this case, we confirmed May-Thurner syndrome using lower extremity computed tomographic angiography and venography. However, on venography, it was impossible to distinguish the left iliac vein from the collateral vein; a thrombus was also seen, although some of the thrombus was not seen clearly. These problems were overcome with use of intravascular ultrasound. We report on intravascular ultrasound guided treatment of May-Thurner syndrome.

May-Thurner syndrome is associated with deep vein thrombosis resulting from chronic compression of the iliac vein against the lumbar vertebrae caused by the overlying common iliac artery. Stent insertion into the compressed lesion is used in treatment of May-Thurner syndrome. Various complications can occur during angioplasty while using a stent. Among these complications, shrinkage of the vein below the stent, a rare complication, was observed in our hospital during treatment of a patient with May-Thurner syndrome. Different complications can occur when venous angioplasty is performed, unlike that when arterial angioplasty is performed.

“Saebora” is a new leaf vegetable perilla (Perilla frutescens (L.) Britton) variety developed from a cross between “Ipdeulkkae1” and YCPL199 at the Yeongnam Agricultural Research Institute, NICS, RDA, in 2004. Purple backside leaf color is a very importan

“Sangbeak” (Perilla frutescens (L.) Britton), is a cultivar for leaf vegetable, from a cross between YPL5 (Ipdeulkkae1/ YCPL187) and “Namcheon” at the National Yeongnam Agricultural Experiment Station (NYAES), RDA, in 2003. The size of fully grown leaf is a important trait in delayed harvesting. The maximum leaf size of “Sangbeak” is 18.5cm, smaller than 21.4cm of a check cultivar, “Ipdeulkkae”1, leading to the constant leaf quality in delayed harvest. The fresh leaf yield of “Sangbeak” is 6% higher than that of “Ipdeulkkae 1” (5029 vs. 4742 kg/10a). For the leaf production, “Sangbeak” could be grown in whole area of South Korea. However, because of its late maturity, seed production culture is available in South Gyeongsang and South Jeolla provinces.
