서양잔디중 난지형 잔디에 속하는 세인트 어거스틴그래스에서 암모늄태 질소와 질산태 질소질 비료의 시비가 브라운팻치 병 발생에 미치는 영향을 알아보고자 본 실험이 수행되었다. 포장에서 재배되고 있는 세인트 어거스틴그래스를 작경 10cm의 플러그를 굴취하여 플라스틱 포트에 이식한 후 뿌리의 활착을 위하여 온실내에서 한달간 재배하였고, 50kg N/ha의 성분비율에 맞추어서 균의 접종 1일전에 시비를 하였다. 잔디포장에서 분리한 Rhizoctonia solani균을 agar위에서 배양시킨 후 균이 배양되어 있는 agar block 을 떼어서 태운 perennial ryegrass에 접종시켰다. 감염된 perennial ryegrass를 다시금 세인트 어거스틴그래스위에다 치상시켜서 잔디로의 접종을 꾀하였다. 그 결과 암모늄태 질소비료나 질산태 질소비료 그리고 무시비상태의 잔디에서의 병발생간에는 유의차가 인정되지 않았으나 질산화 억제제를 처리하여 암모늄상태의 질소 성분이 질산태로 전환되는 것을 억제시킨 구에서는 타처리구에 비하여 6~9배의 발생율을 보였다. 따라서 잔디의 시비와 병발생을 연관시켜 볼 때 암모늄태 질소비료 와 질산태 질소비료 공히 큰 차이는 없으나, 다만 질산태로 변한 후의 질소양분의 토양용탈로 인한 소모를 억제시키기 위하여 사용되는 질산화 억제제는 상당량의 암모늄태 질소성분을 상당 기간동안 유지시키기 때문에 브라운팻치 병발생에 영향을 주므로 그 사용시기에 있어서 신중을 기하여야 하겠다.

Leaf spots in Saintpaulia leaves are caused by temperature drop shock (TDS). This TDS-mediated leaf injury has not been reported in other plants besides Saintpaulia. To investigate how many and what kinds of plants are susceptible to temperature drop shock, Gesneriaceae and Acanthaceae plants were treated with TDS (from $30^{\circ}C$ to $15^{\circ}C$ or $5^{\circ}C$). Yellow or brown spots were found in 26 species or cultivars of 10 genuses of Gesneriaceae plants and in 8 species or cultivars of 7 genuses of Acanthaceae plants. Morphologically and anatomically no similarity was observed among the plants susceptible to TDS. Some plants have very thin and hard leaves, whereas other plants have thick and soft leaves. In spite of this non-similarity, the injury was restricted only to palisade cells as those of Saintpaulia leaves. Also the rapid and irreversible reduction of chlorophyll fluorescence was observed soon after TDS treatment in those plants. These results indicate that leaf injury induced by TDS is a more widespread leaf injury than has previously been thought.

This study will observe the following subjects based on the railroad: First, the development of St. Pancreas Station, which is the gateway to London from other Europe continent, and King's Cross Station, which connects all the intercity within London. Second, the planning characteristic of urban regeneration case which was driven from Camden district, the center of King's Cross Central, which is located in between the two stations, St. Pancreas and King's Cross. Third, based on the the two stations and urban regeneration, this study attempts to investigate the direction of urban regenerating plan and its detailed strategy. As a result, King's Cross Station, St. Pancreas Station and the King's Cross Central area, which is an adjacent area from the two stations, were a slum for a long time. However, the two close stations played a role as the United Kindom and London's railroad network by sharing the common denominator of having the international high-speed railway among the Europe continent and being the connection of National railroads within London. Eventually, based on such potential of railroad traffic, King's Cross Central area was newly regenerated. The consequence of this study has shown that not only the physical modernization of buildings, implementation of compact railroad network supporting both ground and underground of each area or traffic connection was organized in London, but also secured the pedestrian way for easier transfer and planned and allocated facilities by considering citizen's publicness and multilateral use.

미해병대장비를 위한 AV-8B Harrier 항공기의 최초개발계획이 세인트 루이스에 위치한 McDonnell Douglas 사에서 1981년 10월16일 공식적으로 밝혀졌다. 영국정부가 대형항공익을 보유한 해리어기 대신 AV-8B 해리어기를 선정토록 전년에 결정함으로써 미해병대에 대한 미국계획을 확정토록 하였으며, 1981년 8월24일 미.영간 공식양해각서를 McDonnell Douglas, Pratt & Whitney, British Aerospace 및 Rolls-Royce사간의 체결함으로써 해리어(Harrier)기 이세가 출현하게 되었다.
