“Greenstar”, a new Saxifraga cultivar was bred by crossing between “Geumgongjak” with green (YG145C) petals and “Rokseon” with red purple (RP62A) petals in 2003. The selection and flower characterization were conducted from 2003 to 2006 in greenhouses of the National Institute of Highland Agriculture. The flowering of “Greenstar” starts on September 17 for 36 days and the number of flowers per plant was about 290. The flower color is a green (G142C) and the number of petals was 5. Flower width is 2.1 cm and flower length is 1.9 cm. “Greenstar” can be used for pot flower. Fifty percent shading is a good cultural practice against direct sunlight and soft rot disease would occur usually by over-irrigation.

This paper presents eco-friendly planting method to overcome the problems of existing concrete retaining wall and gabion retaining wall, respectively, based on the examination on existing concrete and gabion retaining wall. Prior to doing this, proper design method was provided through pull out test. Planting method using gabion metal net and L shape green net retaining wall were compared and analyzed. According to this study, it is confirmed that reduction of construction period and economical profit in construction can be achieved by both manufacturing at the factory and self procurement at the job site as well as the use of metal net, which is applied as a substitution of existing strengthening material. For the effect of planting method, the use of L shape green net retaining wall shows superiority to environment-friendly gabion retaining wall in its ability to rootage and germination of the grass. The L shape green net retaining wall had excellent performance in helping rootage of grass and prevention of soil leakage, and even if raining period, remarkable damage of planting mat does not occur when planting mat is applied.

At the late 20th century, many problems surfaced from the environmental destruction, which raised the importance of natural environments; technology and ecology started collaborating, the boundary between architecture and landscape destroyed, and developed into a hybrid-oriented form. This study has focused on the use of green architecture materials as a way to furnish natural expression & mood and dealt with water, plants, trees, sand, rocks, light, wind, mist, cloud and their applications on basic compositional elements such as floor, ceiling, walls, openings and other elements. The discoveries revealed that application of green architecture materials is visible in raw material aspect, architectural forming media aspect, technical aspect, and natural image aspect; furthermore, the use of green architecture materials can make the expression of natural design trend possible. Study of green architecture materials should continue to advance through collaborations and co-studies among interior design, architecture, landscape, and horticulture related design fields for the years to come.

This study was conducted to investigate the effect of sta-green and activated carbon on leaf and stem growth of Agastache rugosa as it is affected by different amounts of sta-green and activated carbon. The results obtained are summarized as follows. Growth characteristics including plant height and leaf number were the highest when treated with 30% of sta-green. The weight of fresh leaf and stem of Agastaches rugosa was very low in control. Also, fresh weight of Angelica acutiloba was higher in 10% treatment of activated carbon. However, when the plants were grown in 10% activated carbon. all these promoters were the biggest. Sta-green and activated carbon can be utilized as a soil conditioner in agricultural crop areas.

본 실험은 강원도 영서지역에서 맥류 수확 후 가을채소 파종까지 휴경을 하게 될 경우의 여름 휴경지 관리방안으로 가을채소용 두과녹비작물의 도입에 필요한 기초 자료를 얻기 위하여 수행되었으며, 그 결과는 다음과 같았다. 1. 여름철 휴경을 할 경우 주요 잡초는 바랭이, 방동사니, 쇠비름 그리고 털비름 등 비두과 식물로, 자연적인 두과식물의 출현은 없었다. 2. 두과식물을 6월 중순 로타리 경운 후 파종할 경우 동부와 예팥은 출현율이 높았으나, 돌콩과 헤어리벳치는 출현율이 낮았으며, 동계일년생 두과녹비작물인 헤어리벳치는 하계잡초와의 경합에서 도태되는 경향이었다. 3. 만성형식물인 동부는 잡초의 생육을 가장 크게 억제하였으며, 만성 예팥이나 돌콩, 그리고 헤어리벳치보다 생육량이 많았다. 따라서 우리나라 기상조건에서 여름철 휴경을 할 경우 두과식물의 인위적인 파종이 필요하며, 동부는 여름철 휴경지의 녹비작물로서의 이용 가치가 높은 것으로 판단되었다.

This study was carried to examine the changes in kernel-greenness under different storage conditions in green-kerneled rices, Saedongchalbyeo (Korea) and Hexi41 (China). Rough and brown-rice grains were stored just after harvest under different storage conditions; low (15℃) and room temperature storage, and light and dark storage at 21℃, 24℃, and 27℃. Kernel- greenness was measured by using colorimeter. When the grains were stored in brown rice at room temperature under light condition after harvest, kernel greenness was maintained up to 4 months and gradually faded away until 8 months. However, kernel greenness was maintained up to 10 months storage after harvest at room temperature under dark condition, and up to more than 11 months at low temperature under dark. Rough-rice grains kept the greenness up to more than 11 months regardless of the light and temperature. The higher the storage temperature, the less kernel-greenness when stored in brown rice. Light was the critical factor for degradation of kernel-greenness. For long-term storage of green-kerneled rices, rough-rice storage, or brown-rice storage under low-temperature and dark condition seemed to be desirable for the maintenance of kernel-greenness.

This study aims to develop an evaluation method of green-tourism potential in village level with amenity resources of rural villages, considering human resources of the village. The amenity resources evaluation system was classified into three sub-classes with social, industrial, and natural resources. The system consisted of a relationship diagram between three classes resources and tourists' behavior. The new methodology considers human resources as a key factor for green-tourism potential evaluation of villages, including the amenity resources of three sub-classes. In quantitative method for the criteria, this study adopted a new method of continuous linear score method, which is applying fuzzy theory, not to give score with the existing discrete scoring method with several steps. The weighting values of the evaluation criteria were calculated from the step wise pair-comparision results by AHP(Analytic Hierachy Process) method, which industrial, natural, and social resources have relative weighting values of 523/1000, 319/1000, and 158/1000, respectively. In evaluation of another weighting value by the same methodology, the results showed that the amenity and the human resources have weighting values of 627/100 and 373/1000, respectively. The new evaluation method was applied to make the potential evaluation for rural villages of the study area, which located on Narial-myun, Keumsan-gun, Chungnam province. The development priority among the villages could be suggested reasonably by the new findings of this study, according to the evaluation results showing that the village with high possibility for development in green-tourism has high score in the potential evaluation.

Recent urban sprawl has destroyed various kinds of green space in the city. It has affected quality of people’s life in the city, as well as urban ecosystem. Recent study shows the possibilities of roofs as green spaces in urban central site where the land costs are generally high. This research focuses on Jung-Gu district in Daegu Metropolitan city as a study area and calculates possible area of green roof using 2002 Autocad program based on aerial photographs and land registration maps. And the purpose of this research is to analyze environmental and economic effects of green roof. The environmental effects are as follows. It is expected that 91,106 ㎡ green spaces, 12.13 % of study site, will be added if green roof is performed in the study site. It is assumed that the expanded areas could reduce the highest temperature to 0.5-1.0 ℃ during the summer in terms of environmental effect. And the following shows the economic effects. If green roof and greening urban central site are created as a same size of 91,106 ㎡, it will be expected that the costs of green roof will be much more inexpensive than about 98 billions won. It will be also found that the expense of cooling energy can be saved out about 8 millions won per day in summer, if grass planting is accomplished on the possible areas of green roof in the study site. Therefore, it is desirable to take legal supports such as enacting regulations to activate green roof for more environmental and economic effects. For instance, green roof for public institutions, school and model area selection are desirable method to publicize the effect of greening program for citizen's participation.

쌀보리에서 출수 후 일수에 차이를 두고 풋보리로 수확하여 조제한 미성숙 녹색 보리쌀에 대한 식품소재로서의 가능성을 검토하기 위하여 메성 품종인 새쌀보리와 찰성 품종인 흰찰쌀보리의 일반성분, 유리당, 유리 아미노산, 무기물 및 색도 등을 분석하였다. 출수 후 일수를 달리하여 수확하였을 때 새쌀보리와 흰찰쌀보리의 수분, 조단백, 조지방, 회분, 유리당은 완숙에 가까워질수록 감소하는 경향이었고 조섬유와 전분은 증가하였다. 유리당의 조성을 보면 maltose와 maltotriose의 함량이 다른 유리당보다 높았고, 유리 아미노산은 완숙에 가까워질수록 감소하였으며 유리아미노산 중 alanine의 함량이 가장 높았다. 출수 후 일수가 지날수록β-glucan 함량은 증가하였고 색도는 완숙에 가까워질수록 lightness은 감소하였으며, 적색도와 황색도는 증가하였다. 성분과 색도로 판단할 때 출수 후 26~27 일에 풋보리 상태의 이삭만 절단하여 끊는 물에 60초 정도 blanching 한 후 건조시켜 보리껍질을 제거한 미성숙 상태의 녹색 보리쌀로 조제하는 것이 적당할 것으로 판단된다.

지금까지 우리나라의 기능성게임 개발은 정상인을 위한 게임과 교육용 게임 개발에 편중되어 왔다. 하지만 도움이 필요한 정신 장애인을 위한 치료용 기능성게임 개발은 전무한 상태다. 게임이 주는 긍정적 효과를 활용하여 자연과 인간 모두의 삶에 이로움을 주며, 특히 소외계층인 사회 소수인 및 약자를 위하고, 상업적 측면이 우선시 되지 않는 '정화(淨化)' 개념의 콘텐츠를 '그린콘텐츠'라 정의한다. 정신 장애인을 위한 치료용 게임은 이러한 그린콘텐츠 개념 안에서 개발되어야 한다. 또한 게임의 기술적 측면뿐만 아니라 새로운 콘텐츠 개발 차원에서 기능성게임 개발이 이루어진다면, 그 시장과 사회적 역할은 점점 커져갈 것이고, 그 필요성 또한 더욱 크게 요구될 것이다. 이 연구에서는 정신장애인의 사회적 상호작용과 자기 존중감 증진을 위한 보편적 치료방법 중 하나인 미술치료를 분석하였고, 정신분석학자들의 이론을 근거로 치료용 기능성 게임으로 정신 장애인의 치료가 가능함을 입증하고 개발 프로그램과 설계 로드맵을 제안하였다. 이러한 연구는 추후 이와 유사한 기능성 게임 개발에 유용하게 활용될 수 있다. 그린 콘텐츠 개념이 적용된 다양한 기능성게임 콘텐츠가 개발되어야 할 것이다.

The overall purpose of this study was to investigate pedestrians and commercial business men and employers' recognition on management of street trees and green spaces along street sides. The followings were main results of this study. Both pedestrians and commercial business men and employers mostly perceived positive influence of street trees on urban environment and their business. In addition, pedestrians gave higher scores of positive influence of trees function than those of commercial business men and employers. Pedestrians showed strong intention to participate management activities of street trees or green spaces. This study indicated that negative perception on street trees came from improper management rather than existence of street trees. Therefore, more intensive management actions are needed.

The present study was conducted to investigate the translocation of polyphenols, especially catechin derivatives, from mushroom medium mixed with green tea residues into fruiting body of Pleurotus eryngii. Pleurotus eryngii was grown on the media incorporated by mixing or surface-treated with dry materials including leaf petioles and young stems or leaves of green tea. The dry materials treated in medium did not affect plant height and fresh weight of Pleurotus eryngii body. From the samples of Pleurotus eryngii, the eight main catechin derivatives (-)-gallocatechin(GC), (+)-catechin (C), (-)-epicatechin (EC), (-)-epigallocatechin (EGC), (-)-epigallocatechin gallate (EGCG), (-)-gallocatechin gallate (GCG), (-)-epicatechin gallate (ECG), and (-)-catechin gallate (EGCG), and caffeine were analyzed quantitatively by HPLC. The results showed that EGC in Pleurotus eryngii was 45% more detected, when incorporated with the dry materials, than untreated control. Especially, content of EGCG was increased in surface-treated Pleurotus eryngii up to 3.2 ppm, while it was not detected or reduced in control and other treatments. Caffeine content was greatly increased regardless of treatment method, compared with control (0.1ppm), showing 44 fold-amount in Pleurotus eryngii at early growth stage when incorporated with the dry materials into medium. The results indicates that functional catechin derivatives of green tea would be partly translocated into Pleurotus eryngii throught incorporation and surface treatment with residues of green tea plants.
