This study was carried out to investigate the effects of light intensities on the growth and net photosynthesis of Piper kauzura under different shading levels : 0%, 50%, 70% and 90% of sunlight. Mortality rate was lowest under a 70% shading level but 0% and 90% shading levels were about 46% and 53% each respectively. Plant height was shorter and leaf size was smaller and yellowish under a 0% shading level but increased when light intensity was decreased. However, under a 90% shading level, growth of Piper kauzura was inferior to other treatments. Top fresh weight was about 11.24g under a 50% shading level and about two times higher than that observed in about 6.6g under a 90% shading level. Root fresh weight was about 7.7g under a 0% shading level and was about two times higher than that showed in about 3.84g and 3.64g under 90% and 70% respectively. Total chlorophyll content and chlorophyll a/b rate were increased when light intensity was decreased. Net Photosynthesis achieved the highest under a 70% shading level and maximum photosynthetic photon flux density was 150 molㆍm/sup -2/ㆍs/sup -1/. Therefore, growth of Piper kauzura was good under 50∼70% shading, Meaning that it is an indoor plant that could be highly utilized.

This study was aimed to establish biotop unit of the mixed rural city for the method and process of the biotop mapping system. Survey site was Maejuri of Seunghwan(158ha), Gisanri of Mokchon(132ha) and Namkwanri, Pungsemeon(214ha). So the main process was divided by 4 schemes such as Biosphere, Geosphere, Antrosphere and Evaluation. Also the GIS(geographic information system) was used to make the database of the biotop and biotop complex, analyze the cross-combinations and analyze the characters of the biotop. Biotop mapping system had 5 steps which were proceeded with research goals, constructing the spatial database and attribute database, classifying the 3 types of biotop such as tree/shrub biotop, grass biotop and wetland biotop, cross-analyzing 3 biotop types with land use, habitat characters, relief characters and danger/disturbance elements and evaluating the 3 types of biotop. The results of applicating the biotop mapping system on the research site as followings : The distributions of the land uses in Maejuri, Seunghwan eup in Chonan city were recorded by forest(29.8%), orchard(14.1%) and landscaping around building site(9.0%). Gisanri, Mokchonmeon were composed of forest(64.5%), farm(12.8%) and Namkwanri, Pungsemeon were concentrated rice field(39.6%), dwell district(22.4%). The Tree/Shrub biotop type was reclassed by the forest type, natural and artificial decidous type with natural coniferous. The Grass biotop type was reclassed by the wild grassland type, garden type and peddy field with wild grassland. The distributions of the wet land were pointed high at the wet land type with reed marsh and edge vegetation around wet land in reservoir and river. The evaluation of the mapped bitopes was completed to the following aspect, "amenity" and "environmental education". A high value of 7.13%(1 class) was shown Maejuri, Seunghwan eup. The regions which were studied synthetically are divided to three parts ; the area where have nature and art mixed(Seunghwan), the area which is more artificial because people inhabit there for a long time(Pungsemeon) and the area that ecological environment is threatened by development pressure(Mokchonmeon). Therefore, ecological restoration plan which depends on specific property of the regions should be established. Also the interdisplinary researches were needed to develop the BMS(Biotop Mapping System) in Korea because of the differences with Germany, England's ecological habitat conditions.

Underground space is one of the urban infrastructures which must be actively used because of high land price in urban areas. But bring human negative effects, underground space is not developed actively. And it plays a role just as transportation.<br/> Introduction of Green zone and Object of art can get rid underground space of negative factors. Especially, releases Green zone in underground space negative factors and provides nature to people.<br/> And high-technology like optical fiber make introduction of Green zone in underground space possible. Green zone not only releases negative factors but elevates visual perception and satisfaction.<br/> Active use and development of underground space are to be accomplished through removing negative factors and improving environment in the end.<br/> The Study for introduction Green zone to rise visual satisfaction and perception must be continued on the basis of positive counteraction.<br/>
실내식물 개발을 위한 차광처리가 자생 후추등(Piper kauzura)의 생육에 미치는 영향

This study was conducted to investigate the growth responses of Piper kauzura as influenced by 4 different shading (Control, 50%, 70%, 90%). Under 50 or 70% shading, plant height, number of leaf increased compared with the other shading except leaf length, leaf width, petiole length, internode length. The plant grown under Control was shown smaller and more yellowish green, leaf color and under 90% shading growth was a little inferior to those under the 50 or 70% shading. Chlorophyll contents were increased in proportion to the lowing light intensity. Thus, 50 or 70% shading Piper kauzura seemed to be maintained highly valued growth.

The purpose of this study was on suggesting what is the image and image formation factor of interior landscaping plants. For this purpose, the sixty interior landscaping plants were selected. Selected plants were classified into 9 groups by similar cbaracteristics of plants, for example, leaf color and leaf pattern. Data analyses were performed by semantic differential scale method, mean score and multiple regression algorithm.<br/> The results are as follows,<br/> <br/> 1. Comparing with image assessment, group 9 got the highest score in all aspects.<br/> 2. Comparing with the image assessment of interior landscaping plants, the "impressive" image was obtained the highest score and "bright", "cool", "beautiful" and "fresh" were followed.<br/> 3. Multiple regression analysis was performed to clarify influence degree of the adjectives related to the beauty. The next adjectives were significant check points on assessing the beauty of interior landscaping plants.<br/> The multiple regression formula was as follow;<br/> Y = 0.6534+0.3594(impressive)+0.1103(fresh)+0.1433(ornate) +0.1728(green)-0.0903(crude)+0.0506(soft) +0.1029(light)+0. 0315(warm)<br/> +0.0314(opened)+0.0223(bright)<br/> <br/> Also, Guzmania magnifica was investigated to have the most beautiful image with the results of preference analysis.<br/> Vriesea splendens, Cordyline terminalis Kunth 'Lilliput' and Peperomia sandersii were identified as considerably preferred plants.<br/> <br/>
