Maintenance open spaces and community development in large scale housing development is one of the most important issues. We(UDC) established a resident participation activity for maintenance and use open space with community development in Hachioji New Town from 1997. The purpose of this study is to establish resident participation activities for maintenance and use open space with community development in Hajichioji New Town, and to clarify the characteristics and to on sider about efficiency of the activity. We established Minamino Shizen-Juku as a methodology for maintenance and use open spaces at the same time Hachioji New Town was opened in 1997. The activity has continued by now in 2001. We conducted questionnaire survey to make sure efficiency and characteristics of the activity past three years. Minamino Shizen-Juku (nature friendly lessons) is a resident participation activity in Hachioji New Town. It was established in 1997 as soon as the new town was opened, this year is fifth since it was started. It has three objects. 1)Maintenance and use woody environment, 2) Community development, 3) Continuation and renewal native culture. And it has general course, three special courses and one extra course were established in the activity. 1) General course is an activity participated all of member. It's included farming experience in the native field and seasonal events. 2) Rice growing and woods maintenance course is rice growing and wild wood maintenance in the park as a series of annual farming activities. 3) Benefaction from farm course is started from planting spring vegetable at Mizukoshi(Leader of Minamino Shezen-Juku)'s field. There is the number of participant limit because of the area of the field. 4) Watching nature course is watching seasonal wild flowers, trees, animals and plants to know about native nature. 5) Extra program is programmed to know about native history and tradition. It's planned including participant's ideas. Not member can participate in this course too.

Expressways are often upgraded by widening the lanes and/or by reshaping the roads to be more linear for faster travel time. However, during the process of improving the route of the expressways, the areas where the old expressways used to be are often unused and abandoned. When these neglected sites are left alone, they often become dump sites causing pollution and impacting the surrounding environment. Therefore, it is important to restore the abandoned expressway sites to its full natural beauty. In this study, the abandoned expressway at the Soksa interchange in Pyungchang county, located in Kangwon province was studied for establishing the model of ecological restoration project. Considering the characteristics of the site, the target flora species was chosen to be Quercus species and the target fauna species as amphibians. After the target species were carefully chosen, each species' habitat requirements were studied in order to figure out the appropriate methods toward habitat restoration specifically for these species. In addition, to determine the most efficient method toward restoration of abandoned expressways, the study utilized the planting hole techniques, the crack techniques, and the colonization techniques. In terms of the spatial organization, public education program is incorporated at the main entrance area and the programs for experimenting, and developing vegetation and habitat restoration techniques are placed in the vicinity. In the master plan-to provide natural ecosystem at the site-ASCON (asphalt concrete) was removed first, then plans for restoration including species' habitat restoration were established. Furthermore, the project included plans for improving water quality polluted through non-point source considering the surrounding nearby road and farm lands. Finally, the study established a planning process that will experimentally apply to the abandoned expressway restoration method. In the future, there will be a continuous monitoring of the methods applied to verify if the restoration methods are effective. Also, new restoration techniques should be available according to a variety of abandoned expressways' characteristics.

Purpose: Path planning and tracking algorithms applicable to various agricultural operations, such as tillage, planting, and spraying, are needed to generate steering angles for auto-guidance tractors to track a point ahead on the path. An optimal coverage path algorithm can enable a vehicle to effectively travel across a field by following a sequence of parallel paths with fixed spacing. This study proposes a path generation and tracking algorithm for an auto-guided Korean tractor with a tillage implement that generates a path with C-type turns and follows the generated path in a paddy field. A mathematical model was developed to generate a waypoint path for a tractor in a field. This waypoint path generation model was based on minimum tractor turning radius, waypoint intervals and LBOs (Limit of Boundary Offsets). At each location, the steering angle was calculated by comparing the waypoint angle and heading angle of the tractor. A path following program was developed with Labview-CVI to automatically read the waypoints and generate steering angles for the tractor to proceed to the next waypoint. A feasibility test of the developed program for real-time path tracking was performed with a mobile platform traveling on flat ground. The test results showed that the developed algorithm generated the desired path and steering angles with acceptable accuracy.

This study is designed to analyze the trends of professional services in Landscape Architecture during the past 5 years(1987-1991) in Korea. The data were collected from 1,117 projects from 56 engineering and landscape architecture firms. The findings are summarized as follows: 1) The projects have been increased annually by 19 percent in numbers and by 47 percent in money terms. 2) The main sources of projects are local governments and corporations. However the private sector comprise 31 percent in projects number and 46 percent in money terms. 3) The public park and tourism site development comprise a half of the projects. Recently recreational forest, golf, amusement and large housing site development have increased very rapidly. 4) In terms of workscope they are devided by 'complex' project which include extensive engineering works and 'simple' project which contain mostly planting design. The former include receational project with average 5 or 6 months contract period, and the later include housing and building site design with 2 or 3 months period. 5) Two types of consulting firms are typical. One is comprehensive engineering firms with urban planning section and few landscape section. The other is specialized professional firms with urban planning or landscape architecture. 50 percent of the project was done by comhensive engineering firms and 60 percent was done by urban planning section. The implication of these findings are broad: Firstly, We have to meet the demands in private secter mostly in recreation and leisure related projects. Secondly, landscape architects and project managers need more professional skills and coordination ability to deal with 'complex' projects. Thirdly, to enhance the quality of professional services it is required to have enough work time and higher service fee through legal and institutional enforcements.

International exchange gets active in nations with the increase of Internet use and heading toward digital age. Thus the communication conveying image of nations effectively plays an important role in an international society. Sports events are regarded as important international exchange events and good opportunities for public relations of one's own country and taken as tools of planting good images in other nations. This study surveyed the concept and history of uniform through the documents and previous studies in order to find the aesthetic characteristics of sportswear uniform applying the image of national ensign and investigates the origin and start time in Korea of selected 6 sports items. As a result of finding the expression way of ensign image and drawing the aesthetic characteristics by analyzing the use and variation of ensign colors, the use of colors other than ensign and reflection of ensign form in collected 60 sports uniforms, this study could draw the symbolical beauty, beauty of variation and beauty of brevity. First, symbolical beauty is the aesthetic characteristics expressing uniforms by using the pattern ensign symbolizes and ensign colors themselves or enlarging a part of ensign. Second, beauty of variation is the aesthetic characteristics creating geometrical new patterns in uniform through the distortion and exaggeration of ensign shape, or transforming the colors themselves of ensign. Third, beauty of brevity is the aesthetic characteristics using other colors only as decorative factor while applying the main colors of ensign to the most part of uniform, or unifying the uniforms with only one color of ensign. As a result of survey, the proportion of the symbolical beauty was highest in summer season and beauty of brevity and beauty of variation followed and the proportion of beauty of variation was highest and the symbolical beauty and beauty of brevity followed after that in winter season. This study found the way of expressing image of one's own country in sports uniform through this article, expecting the exact recognition on sports uniform and the diversity of sports uniform design in which the images of the nation are expressed more variously.

본 연구는 조선시대 궁궐 내에서 일어났던 친잠문화의 배경과 공간적 특징에 대한 탐구하는 것이 목적이다. 조선은 유교적 중농주의 국가로서 국초부터 농업 못지않게 양잠업 장려에 열의를 보여 양잠 생산성을 극대화하기 위한 다양한 노력을 진행해 왔다. 그러한 노력의 일면으로 조선 왕실은 궁궐 내에서 친잠활동을 하게 되었다. 조선은 초기 태조 연간부터 궁원 곳곳에 뽕나무를 심었으며, 세조는 동궁(東宮) 근처에 잠실(蠶室)을 설치하여 세자를 비롯한 궁중 사람들에게 양잠의 중요성을 수시로 알게 했다. 성종 연간에는 조선 최초로 창경궁 후원에 채상단을 만들어 친잠례를 거행하였고, 이후 채상단은 위치를 달리하며 광해군 때까지 유지되었다. 그 후 영조 연간에는 경복궁에 채상단과 정해친잠비(丁亥親蠶碑)를 건립하였는데, 이는 경복궁 유지에 대한 영조의 애착과 양잠의 권면에 대한 적극적 의지의 산물이었다. 경복궁 유지에서 터가 고르고 뽕나무를 심기 적합한 동편이 선택되어 채상단을 축조했으리라 가늠해 볼 수 있는데, 이 장소는 세종 연간 잠실이 있던 장소이기도 하다.

콩 씨스트 선충은 콩 수량에 가장 심각한 피해를 입히는 선충이며, 콩 씨스트 선충으로 입는 피해가 연간 전 세계적으로 9백만 메가그램이나 되는 것으로 추정되고 있다. 콩 씨스트 선충은 식물 영양분을 먹어 뿌리의 성장을 지연시키고 근류균의 고정을 억제함으로서 수량의 감소를 가져 오게 된다. 콩 씨스트 선충을 방제하는 근본적인 방법은 저항성 품종을 재배하거나 윤작을 하는 것이다. 유전적으로 콩 씨스트 선충의 다양한 레이스들과 상업적 품종들의 제한된 저항성 품종들이 오랜 시간에 걸쳐 레이스 전환을 가져왔고, 이러한 이유로 콩 씨스트 선충의 방제가 매우 어려운 실정이다. 이 논문은 콩의 중요성, 콩 씨스트 선충, 콩 씨스트 선충 저항성에 대한 연구현황, 그리고 전망에 관해 고찰하였다.

The negative impact of climate change on the agricultural sector is rapidly increasing, and it is urgent to prepare policies at the government level to mitigate it. In the case of Rwanda's agricultural sector, which lacks the government's budget and farmers' capital, efficient and effective policy implementation is of paramount importance. To this end, rather than establishing related policies in the public sector from the top down, it is necessary to establish a bottom-up customized policy that is reflected in policy establishment by identifying the characteristics and behaviors of farmers who actually participate in adaptation activities. In this study, the effects of farmers' characteristics and farmers' perception status/adaptation status to climate change on the selection of adaptation methods for climate change were analyzed. 357 rice farmers randomly selected from Eastern Rwanda were surveyed to explore the information related to farmers' perception to climate change and adaptation methods as well as basic information of the farm. Research shows that the probability of selecting a variety of adaptation methods rather than not responding to climate change increases the younger the age, the higher the education level, and the easier access to climate information and credit. As a policy proposals, it is judged that public support such as strengthening agricultural technology support services, including more detailed guidance for elderly and low-educated farmers, and improving access to farm loan services by agricultural financial institutions is needed. In addition, it is necessary to adjust the planting time and cultivation method, provide timely information related to climate change, and provide crop variety improvement services to farmers.
