[ ]한국산 명나방과(Pyralidae)에 관하여는 이미 필자(1976)에 의하여 언급된바와 같이 1889년 영국인 곤충학자 J.H. Leech가 처음으로 9종의 신종을 발표한데 이어 현재까지 300여종이 기록되어 왔다. 그러나 이들의 기록이 여러종류의 발표문에 산재해 있는 상태로 체계적인 정리가 이루어진바 없으며 학명뿐아니라 우리말 이름조차 갖가지로 쓰여지고 있어 곤충명 사용에 혼란이 야기되고 있는 실정이다. 이에 필자는 현재까지 발표되었던 종들을 조사하여 최근의 분류체계에 따라 학명 및 그들의 동의어(Synonym)를 정리함과 아울러 우리말 이름도 먼저 명명된 이름이나 또는 현재 많이 사용되고 있는 이름을 택하여 통일화하고 ( )안에 그 이명을 표시하였다. Evergestiinae(새들명나방아과, 신칭)은 현재까지는 주로 Pyraustinae(들명나방아과)에 포함되는 족(Tribe)으로 취급되어 왔으나 최근의 분류체계에 따라 독립된 아과로 취급하였다. 이들에 대해서는 Leech에 이어 일본인 Shibuya(1927년에 의하여 13종, 박세욱등 (1958, 1969)에 의하여 27종이 새로 기록되는등 1968년에 출판된 한국 동물명집 곤충편에는 94종이 수록되었다. 최근 필자(1976)에 의하여 우리나라 미기록종으로 발표된 24종과 기타 국내외의 문헌을 통한 기록의 근거를 기초로 작성된 이 목록에는 Evergestiinae에 1속 3종, Pyraustinae에 53속 123종이 포함되었으며 학명이 불분명하거나 채집의 근거가 불확실한 4종은 후미에 별도로 기재하였다. 분포란의 괄호안에 명시된 채집지는 필자에 의하여 채집 확인된 종들로서 그들의 표본은 농업기술연구소 곤충연구담당관실 표본실에 소장되어 있다. 다른 아과에 관하여는 정리가 완료되는대로 추후 발표할 예정이다.nemella hengsungica, Aphelenchoides besseyi 등으로 2아목 7과 11종이었다.는 내연가공한 옷생산에 사용되지 않는 것이 타당하겠다. 주아의 즙액에 의해서도 C. amaranticolor에 기계적 전염이 되었다. 7.

Potato virus Y, Potato virus S, Potato virus M 등과의 혈청학적 유연관계를 조사한 바, 마늘 모자이크 바이러스는 이들과 구별되는 다른 바이러스라고 생각된다. 13. 마늘의 모자이크 감염주에서 단일계통으로 분리하여 본 실험에 사용한 바이러스는 마늘의 바이러스 무감염주를 얻을 수가 없기 때문에 직접 마늘잎에 접종해서 모자이크톤의 병원이라는 것을 확인할 수 없었지만, 검정식물상의 반응, 혈청학적반응, 전자현미경적 관찰등의 간접적인 조사 결과로 미루어 미인록의 마늘모자이크 바이러스라고 생각된다

Quadrotor with limited flight time due to battery level can have the extended mission life by applying energy harvesting technology. Bio-inspiration from the birds' locomotion of flight and perch-and-stare can make energy consumption efficient, and energy harvesting technology can generate energy. In order to charge the battery with solar power, the drones are required to be in a position without shade. In the mountainous terrain, a novel mechanism is required in order to be located stably at the top of the tree or the inclined rock. In this study, we propose an analysis of the origami structure and the concept design of the perching mechanism with two stable equilibrium states. The origami structure composed of compliant material can be applied to the perching mechanism that can be locked passively. Moreover, the experimental results of the trajectory and perching test are discussed.

Background : Dungkunma (Dioscorea bulbifera, commonly known as the air potato, air yam, bitter yam, cheeky yam, potato yam) is a species of true yam in the yam family, and has been used as folk remedy to treat conjunctivitis, diarrhea and dysentery, etc. This study was carried out to investigate shelf-life and quality of fresh-cut Dungkunma (Dioscorea bulbifera) in order to elevate utilization of Dungkunma as fresh food. Methods and Results : Before vacuum-packaging (in polyethylene/polypropylene film (100 ㎛, 15 × 20 ㎝, 75 ± 2 ㎝Hg) and storage at 2℃, Dungkunma were peeled out and cut to dice type (2.0 ± 0.5 ㎤), and then washed and blanched (30 sec at 90 ± 2℃ hot water and 2% NaCl solution) and pre-dried at room temperature, 40℃ and 50℃ for removing surface water. Each peeled dice Dungkunma were packed 50 g in polyethylene/polypropylene film (100 ㎛, 15 × 20 ㎝) with vacuum treatment (75 ± 2 ㎝Hg) and stored at 2℃ for 90 days. Hardness and adhesiveness of Dungkunma blanched by 2% NaCl and pre-dried at 50℃ (SB50) was the highest and increased and decreased, respectively, but changes was the least during storage. Lightness and yellowness of stored Dungkunma in all treatments decreased slightly and redness increased during storage but changes of color was the least at SB50. On vacuum packing, SB50 showed 1.88 log CFU/g of total aerobic bacteria during 90 days, and E. coliwas detected in all treatments during whole storage periods. Dioscin and allantoin content of SB50 was virtually unchanged during the storage. Conclusion : Consequently, the results of this study suggest that vacuum packaged Dungkunma after blanching at 2% NaCl could be effective to prolong the quality of fresh-cut Dungkunma and could be easily used.

This study was conducted to measure the effect of PE film mulching and irrigation methods on the growth, yield and antioxidant activity of potatoes tubers, in order to examine the possibility of cultivating potatoes in winter season in vinyl greenhouse on the reclaimed tidal land with weak ground inside the sea wall currently completed. The test was conducted on the sandy loam soil (Munpo series), and its salt concentration was 0.42% at the time of planting. The emergence speed per kind of PE film mulching was in the order of black > coloration > transparent > green color, with the black color showing the fastest speed. The temperature change during a day per kind of PE film mulching was in the order of transparent > coloration > green > black color. As for the salt concentration in the soil for each different way of water management, the salt concentration in the treatment of drip irrigation with 1 week interval was lower than that drip irrigation with 2 weeks interval. As for the growth of above-aerial part, plant length was higher, number of tiller and leaves were more and dry weight of above-aerial part was larger in the treatment of drip irrigaton with 1 week interval than drip irrigation with 2 weeks interval. As for the yield of potatoes depending on were higher with pear color vinyl treatment. each way of water management, the yield in the treatment of drip irrigation with 1 week interval was more than drip irrigation with 2 weeks interval. The yield for each different kind of PE film mulching in the weekly drip-irrigation management section was in the order of transparent ≥ black ≥ coloration ≥ green color. In both of total phenol content and DPPH free radical activity experiments, the content and activity

An exotic parasitic wasp Anisopteromalus apiovorus of Pteromalidae was newly recorded in Korea. Specimens of this species have been collected in Gimhae of Korea since 2012. External morphology of this species was described in detail and diagnostic differences of this species from the related species and the host insect were also given. The funicle segments of female antennae are 1.2 to 1.5 times longer than those of Anisopteromalus calandrae, an sister species. Body color is gold-glossy black and with dense creamy-white hairs on the surface. This exotic species has been originated from the African continent including Democratic Republic of Congo and Cote d'Ivoire, and then intruded into other countries, for instance, Korea. This is the first distribution record of this species except the country of origin after original description as a new species. Although little is known about the life history or ecology of this species, we found that a new host of this small parasitic wasp is Lasioderma serricorne of coleoptera through present study. And this species possibly be a new agent of biological control for economic pests. It was presumed that the invasion of Anisopteromalus apiovorus into Korea was prior to November of 2012.

Corythucha marmorata Uhler was newly recorded in Korea as a invasive species at Pohang-si, Gyeongsangbuk-do, Korea in 2011 and at Changwon-si, Gyeongsangnam-do, Korea in 2012. Adults of this species show reticular forewings with a lot of transparent membranes and also show pterigoid process of paranotum with strong processes. This invasive species was originated from North America, and then intruded into Europe and Japan. This species is presumed became an epidemic horticultural pest at present and it is injuring almost of Asteraceae leaves. It was presumed that the invasion of Corythucha marmorata into Korea was prior to September of 2011.

Leptoglossus occidentalis Heidemann, 1910 was newly recorded in Korea as a invasive species at Gyeongsangnam-do, Korea in 2010 and 2011. Leptoglossus Guérin-Méneville, 1831 is also newly recorded Coreid genus in Korea. The diagnostic shape is expanded leaf-like hind tibiae. The origin of this species is North America and it has been rapidly propagated around the world as a pest. This bug recognized as a pest on almost of Pinaceae plants and they suck on developing cones, so the monitoring on the present invasion of this species in Korea is urgent. It was presumed that the invasion of Leptoglossus occidentalis into Korea was before 2010 with present study.

One of the ultimate purposes of ecumenical dialogue is to share, beyond mere understanding and reconciliation, special gifts of traditions and spiritual experiences. This paper aims to explore Luther’s doctrine of justification in the ecumenical dialogue, especially investigating “Joint Declaration on the doctrine of Justification”, which is ecumenical document between Lutherans and Roman Catholics. This document says that Lutherans and Roman Catholics has reached a fundamental consensus on the gospel, though they still admitted that even after several years of dialogue they still had differences. The significance of this paper is twofold. First, it will advance Luther research by bringing to light an important ecumenical interpretation and emphasis of Luther’s theology of Justification. It will also contribute to contemporary ecumenical efforts by focusing attention on the dialectic methodology of faith and love in Luther’s theology. In regard to understanding of Luther’s doctrine of Justification in the ecumenical context, this paper suggests two points, which hopes to produce effective results. First, Luther’s teaching should be interpreted in spiritual dimension, that is to say, in terms of mystical union with Christ. Second, it should be understand essential basis of faith for social ethics of Christians. Ultimately, the paper asserts that Luther’s theology of Justification provides underlying principles for Christian ethics today, and that for Luther, faith and love are integrated in his theology.
