This study was carried out to provide preliminary information to grasp how many particulate matter (PM) which is a problem in urban area are absorbed and removed by street trees. The morphology, size and element composition of PM deposited on leaves of five street trees (Quercus glauca, Q. myrsinaefolia, Ginkgo biloba, Prunus serrulata var. spontanea, and Pinus densiflora) in Jinju city, South Korea were analyzed. The size of PM was classified into three as PM2.5 (0.2~2.5 μm), PM10 (2.5~10 μm), and PM100 (10~100 μm). The element composition of PM deposited on the leaves at the study sites mainly comprised of O, C, N, Si, and Al. The PM at industrial area and university campus was irregular and spherical shape, respectively. Total PM accumulated on the leaf surfaces of P. densiflora was 71.65 μg/cm² at industrial area and 40.66 μg/cm² at university campus, which was significantly higher than the other species. The ratio of PM2.5, PM10, and PM100 deposited on the leaves was 9.2%, 37.0%, 53.8% at industrial area and 15.8%, 27.1%, 57.1% at university campus, respectively. P. densiflora deposited the most PM2.5, PM10 and PM100 in leaf wax at the study sites, which was significantly higher than the other species.

People today spend 80% of their time indoors and have been showing keen interests in air quality since 2015 due to harmful chemical issues such as humidifier disinfectants. Although plant-based air purification method is widely known to the public, its objective performance and air-conditioning efficiency have been limited. In particular, in the case of publicly used places frequented by many and unspecified persons, high air-conditioning wind volume is required and it is difficult to secure the required total wind volume with the current air purification method using plants. Therefore, in order to secure air-conditioning wind volume when linked with plants, this study aims to verify stability in using vegetation units that can be linked with building air-conditioning equipment. To this end, vegetation units and AHU were linked for 40 hours under no irrigation conditions and ecological environmental changes were monitored objectively. Pressure loss by total wind volume of vegetation units was verified, and soil moisture, Chlorophyll, and FVC were monitored. First, soil moisture was converged to 0% at a spot where wind volume is concentrated in vegetation units. In both of two types of tree species, chlorophyll showed a change of 1.2 - 2.9 SPAD and FVC showed a change of 4-29% after the experiment.

Light is very important for plant growth and a major limiting factor in indoor plant cultivation, such as in balconies. This study was conducted to investigate the light intensity and lettuce (Latuca sativa L.) growth in an apartment balcony affected by the direction of balcony. Photosynthetic photon flux (PPF), air temperature, and relative humidity in the east-, south-, or west-facing balcony were measured for a year. The lettuce was grown in the east-, south-, or west-facing balcony. The time and amount of light entering into the balcony differed according to the direction of the balcony window. Whereas light entered into the east-facing balcony from sunrise to noon, it entered into the west-facing balcony afternoon before sunset. The temperature and humidity in the balcony also varied according to the direction of the balcony window. Daily Light Integral (DLI) in the south-facing balcony was 20~50% of outdoor and DLI in east- or west-facing balconies was 10~20%. Also, the environmental characteristics of the balconies were affected seasonally. In the spring (from March to May), the DLI was around 10 mol･m-2･day-1 and the average temperature was around 25°C. But the DLI was below 10 mol･m-2･day-1 and the average temperature and relative humidity were around 30°C and over 60%, respectively, in the summer (from June to August). In the balcony, the average temperature was maintained around 10°C even in winter, which is a condition of freezing outdoor. Growth of the lettuce in the south-facing balcony was better than that of the other directions. This is attributed to better environmental conditions of south-facing balcony. Therefore, considering the environmental characteristics of the balcony, selection and management of crops with relatively low light demand like leafy vegetables are required. It is also recommended to cultivate crops from autumn to spring.

The appropriate soil depth for each species should be determined by taking into account the visual quality of the plant, including the growth conditions of the trees and total photosynthesis. The purpose of this study was to investigate the growth characteristics -height, root collar diameter, dry weight- and quality index according to soil depth. Therefore this study proposed suitable plants according to container size (soil depth) when creating a container garden. The result are as follows; Pinus densiflora, Pinus parviflora and Nandina domestica have poor growth and low ornamental value at 15 cm depth. Therefore, theu will be available at a minimum depth of 20c m. Thuja occidentalis grew in 15 cm of soil depth and had a normal visual value, but it was desirable to plant 20 cm of soil depth. Ilex serrata grew at least 20 cm above depth but it was not suitable for container garden because of its low value of ornamental value. Syringa vulgaris had little difference in growth depending on soil depth. Considering the visual quality, it will be possible to plant for container gardening at a soil depth of 20 cm or more. Container gardens are an alternative to forming green spaces in places where planting is difficult in the city. Therefore, appropriate containers and plants should be selected.

Recently, the air quality issue came to the fore to the occupants of indoor areas with the detection of a large amount of indoor air pollutants such as formaldehyde that causes headache and atopic dermatitis. In order to address this issue, the use of indoor air purifying plants is considered positively as an ecological improvement option. However, the objective performance verification on indoor air-conditioning air volume has not been sufficient. This study aims to verify possible linkage with a building’s air conditioning equipment in order to optimize indoor air-conditioning effects by vegetation bio-filters. To this end, 4 different types of air filter material and AHU (Air Handling Unit) system were linked under air conditions of total wind volume of 400, 600, 800, 1,000 CMH and pressure loss by material was monitored objectively. Finally, material-specific power consumption for system operation was calculated to review energy efficiency. As for pressure loss by material, in terms of total wind volume of 800±1.8 CMH, Pre filter was lowest at –11.69 mmAq and LMF-based vegetation mat was highest at –219.94 mmAq. Based on this, as for material-specific power consumption, the Pre filter, which has the lowest pressure loss, was expected to have power consumption 94.7% lower than the LMF-based vegetation mat.

A noble method was developed for determining indoor greenery ratio through a digital camera and image analysis. Photographs with 10 different exposure compensations level were taken at indoor room using the function of “Partial color (green)” in a digital camera under varied indoor light conditions. RGB photographs were converted into Lab mode using [Image/Mode] function of Photoshop software program. The number of green pixels were calculated within 1 to 127 level (equivalent to -127 to -1 of Hunter a* value) through “Channel a” in [Histogram] function of the software. Greenery ratio was calculated by maximum green pixel number of an exposure compensation in relation to total pixel number, as maximum green pixels number would be obtained under a certain exposure compensation level when it minimizes achromatic color by partially excessive lower or higher light condition within certain area of photograph. When greenery ratio obtained from this method was compared with general greenery calculation of green area through manual selection, coefficient of determination was 0.9852, indicating appropriate greenery ratio estimating method. When applied to vertical planter of veranda and office, greenery ratio varied at 0.53～14.96%. In our experimental condition, error of the function, “Partial color” by the digital camera was within 0.013, while the error of the function, “Channel a” by the software was within 0.005.

This study was conducted to investigate the effects of rooting promoters on rooting and seedling quality in Buddleja davidii ‘Empire Blue’, Hydrangea paniculata ‘Magical Candle’, Hydrangea arborescence ‘Annabelle’, Stephanandra incisa semi-hardwood cuttings. IAA and IBA (500, 1000, or 1500 mg･L-1 soaking for 30 minutes and 3,000 mg･L-1 dipping for 10 seconds) or RootoneTM were used as rooting promoter. In B. davidii ‘Empire Blue’, IBA 1,500 mg･L-1 soaking reduced rooting percentage than control, but the effect of rooting promoters was generally insignificant. Number of leaves and shoot length were reduced in RootoneTM and IBA 1,500, 3,000 mg･L-1 treatments. IAA 1,000~3,000 mg･L-1 and IBA 500 mg･L-1 treatments showed better mat formation than control. The rooting ratio of H. paniculata ‘Magical Candle’ increased to 66.7% in IBA 1,500 mg･L-1 soaking treatment compared with 26.4% in the control. The mat formation was higher in RootoneTM, IAA and IBA treatments compared to control, and root length showed longer tendency in IAA and IBA except RootoneTM. The rooting ratio of H. arborescence ‘Annabelle’ was highest at 70.8% in the control and auxin treatments showed negative effect on the rooting percentage except IAA 1,000 mg･L-1 soaking treatment. The mat formation was very poor in IBA 1,000 and 1,500 mg･L-1 soaking at 1.1 and 1.3, respectively. S. incisa showed high rooting percentage at RootoneTM (80%) and IAA 1,500 mg･L-1 (80%) treatments compared to control (51.7%). Root length and dry weight were high in IAA 1,500 mg･L-1 soaking treatment. As a result, B. davidii ‘Empire Blue’ and H. arborescence ‘Annabelle’ did not need rooting promoter for stem cuttings, and IBA 1,500 mg･L-1, IAA 1,500 mg･L-1 soaking treaments could be used to improve rooting and seedling quality of H. paniculata ‘Magical Candle’ and S. incisa semi-hardwood cuttings, respectively.

Effects of substrates, non-aggregated medium and Rootone on the rooting of spearmint (Mentha spicata), peppermint (Mentha x piperit) and catmint (catnip:Nepeta cataria) were investigate and results were as follow. Five types of substrate (saproilite (S), peatmoss (P), S:P 75:25, S:P 50:50, S:P 25:75v/v) were used as rooting media. In the rooting rate and number of roots, peppermint and catmint had higher values in saprolite with significant, but spearmint was shown the better result in S:P 25:75 mixed substrate than saprolite without significances. Root length of spearmint was promoted in mixed substrate of S:P 50:50 and 75;25, and catmint was better in saprolite substrate. Rooting rate and number of roots were shown more decreased in single peatmoss substrate and mixed substrate than saproilte. The effects of aggregated medium (S) and non aggregated medium (tap water) on the rooting of different stem part of mints were tested. Rooting and number of rooting of spearmint and peppermint in water medium were more increased than in saprolite medium. But catmint was not rooted in any medium. Rooting of upper parts with growing points was more increased than under part of stem, which was relative hardy. In Rootone treatments test on rooting of stem cuttings, all treatments very strongly promoted the rooting and number of roots not only in upper stems but also in under part of stem in saprolite and water medium. Rootone treatments (drying 10 minutes after dipping on wetted stem) was very effective in water medium. Especially catmint treated with Rootone promoted a root formation in water medium This research was clarified the possibilities of rooting on spearmint, peppermint, and catmint cuttings in water medium, when especially treated with Rootone.

This study was carried out to examine the effective wet harvesting solution for development of wet distribution system in standard chrysanthemum (Dendranthema grandiflorum) ‘Baekma’. The cut flowers were treated immediately in floral preservative solutions or dry condition after harvesting, and then the effects on quality of cut flower were compared. Also, we investigated the effects of NaOCl and sucrose on vase life and quality of cut flower. When the cut flowers were treated immediately in tap water, Chrysal OVB, Floralife, Hiflora solutions after harvesting, flower diameter and fresh weight of cut flower increased compared to dry condition treatment. In single treatment of 100 mg･L-1 NaOCl as wet harvesting solution, flower diameter and fresh weight of cut flower increased more than other treatments, and vase life was prolonged to 1.5 days than control. But, flower diameter and fresh weight of cut flower decreased in 0 or 200 mg･L-1 NaOCl. When the cut flowers were treated in combination solution of 100 mg･L-1 NaOCl and 0.1% sucrose, the flower diameter was the largest by 9.8 cm, and fresh weight of cut flower was maintained the highest in holding solution. On the other hand, flower diameter and fresh weight of cut flower were lowest in combination solution of 100 mg･L-1 NaOCl and 2.5% sucrose. There was no difference in vase life between treatments mixed with NaOCl and sucrose. Therefore, it was suggested that treatment mixed with 100 mg･L-1 NaOCl and 0.1% sucrose as wet harvesting solution was the most effective for vase life and quality of cut flower in standard chrysanthemum ‘Baekma’.

This study investigated the effect of leaf form or phenotype and light intensity on the toluene, xylene, and ethylbenzene removal of three foliage plants. Green and variegated forms of Ardisia pusilla, Scindapsus aureus, and Hedera helix plants were grown under 10 and 20 μmol･m-2･s-1 light intensities for 8 months and were tested for their volatile organic compound (VOC) removal efficiency for 15 h. In general, variegated forms of the plant species have higher VOC removal after 15 h of VOC exposure than green plants, particularly when grown in 10 μmol･m-2･s-1. This is more evident in A. pusilla and S. aureus than in H. helix. The highest rate of toluene, m-, p-, and o-xylene removal per hour by plants grown under 10 μmol･m-2･s-1 was achieved by variegated A. pusilla, while for ethylbenzene, variegated A. pusilla and variegated H. helix had the highest removal rate per hour. In plants grown in 20 μmol･m-2･s-1 light intensity, variegated and green H. helix have the highest removal rate per hour of toluene and m-, p-, and o-xylene. For ethylbenzene, variegated A. pusilla and green and variegated H. helix had the highest removal rates per hour. The plant with the lowest removal rate per hour for all five VOCs was green S. aureus grown under both light intensities. The percentage VOC removal rate of variegated over green plants was 22% higher at a lower light intensity

This study was conducted to investigate the change of workers physiology and sensitivity according to the plant decoration activity using electroencephalographic (EEG), electrocardiogram, and semantic differential (SD) methods on 31 male and female workers in their twenties. Plant decoration activity and writing documents on a computer (WDOC) were carried out for 10 minutes each. The relative slow alpha power spectrum (RSA) has been highly exhibited at most measurement points at plant decoration activity compared to WDOC, and ratio of alpha to high beta spectrum (RAHB) was higher in the parietal lobe responsible for visual function in charge of visual function and showed stable and relaxed effect with little stress or tension. In addition, the relatively fast alpha power spectrum (RFA), which is responsible for visual function, after WDOC was higher than after plant decoration activity in the left parietal lobe (P <.05). Although not statistically significant, the relative high beta power spectrum (RHB) and the ratio of mid beta to theta (RMT), which are stress concentration indexes with tension, were highly regarded as a whole when performing WDOC. There was little difference in heart rate between after both activities. However, high frequency (HF) component indicating parasympathetic nervous system activity was more highly active after WDOC than Planting decoration activity, and the low frequency (LF) component indicating sympathetic nervous system activity tended to be lower after WDOC than after planting activity meaning that plant activity have a sense of stability than WDOC and these results were similar to brain wave analysis. In addition, the sense of comfort, naturalness, calm were significantly higher when the plant decoration activity was performed than when the WDOC was performed in the SD emotional vocabulary survey. These results could be interpreted that plant decoration activity induced more physiologically and psychologically stability and relaxation than WDOC, and enhanced attention ability in appropriate awakening state.

The traditional temple in the urban landscape is a place of historical and cultural heritage with ethnic values within the city. However, when viewed in a landscape perspective, several problems are implied. This is because the temple is restricted within the territories of the temple when there is a great need for space for gatherers and tourists. Thus, a dissimilar landscape planning and management system from the current traditional temple is required. In this study, the landscape of the traditional temple in the city viewed from Bongeunsa temple grounds was set as the study area and the representative viewpoints within the temple grounds were used as a base of describing the landscape's image and the factors of the landscape preference was also derived. These factors were then used as a base to create the landscape preference map for the region of Bongeunsa temple to present a visual representative of the place. The factors showed a significant impact on the landscape of Bongeunsa temple were selected to aesthetics, amiability and complexity. The higher the preference of these factors was, the higher the preference was for the landscape as well. The factors representing the landscape image and the landscape map according to the landscape preference of the temple were created to allow regions that showed both low and high levels in the landscape image and preference within the grounds to be visually classified and regions that needed improvements were also displayed. Furthermore, it also allowed elements to be extracted from it. The results of this study was an attempt in creating the landscape map formed based on the landscape of the temple grounds.
