The purpose of this study was to investigate the distribution of vascular plants in Mt. Daedeukbong. The study is significant because surveying the flora of old-growth forest in Mt. Daedeukbong is a way of understanding what kind of plant species exist in DMZ as the geographical characteristics of Mt. Daedeukbong adjacent to Korean DMZ have the role of a buffer zone connecting the DMZ and its southern region. We collected the vascular plants 7 times from May 2015 to May 2017 and found a total of 393 taxa consisting of 84 families, 245 genera, 341 species, 4 subspecies, 43 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 8 taxa, and the endemic species were 6 taxa. 44 taxa were listed as specific plant species based on phytogeographical in the investigated area. 23 taxa were recorded as naturalized plants, and the naturalized rate and urban index were 5.3% and 8.7%, respectively.

The historical exchanges between the Republic of Korea and Japan have broadly occurred, in terms of both political and cultural aspects, from ancient to modern times. Regarding ancient gardening culture, in particular, Asuka developed gardens with the gardening techniques passed down by the Baekje people. The development of the basic form of a garden pond along with its characteristics, established through such exchanges, is suggested by investigating its components through analysis of data from the gardens of Baekje and Asuka. In terms of the garden pond structure, homogeneity was confirmed between Baekje and Asuka, with a linear rectangular form as the basic design. In addition, the vertical construction technique was used by both ancient kingdoms. In terms of the types of stone used in building the shore of the garden pond, Baekje used diverse types such as natural stone, crushed stone, and cut stone. In contrast, rounded river stone was used by Asuka. Regarding the floor of the garden pond, Baekje used soil, which enabled the planting of lotus flowers. In contrast, Asuka used stones to pave pond floors, which made the growth of plants impossible. In terms of layout, Baekje used ornamental stones for pond landscaping, while Asuka used manmade island and water intake facilities in their pond construction. The effects of Baekje's garden culture on Asuka's garden building can be seen from its influence on the form of the garden pond and shore construction style. In terms of the construction of the garden pond's shore with the same stones and the stone flooring, the garden ponds of the Asuka Kingdom reveal technically unified and refined aspects.

The purpose of this study was to identify detailed factors that affect visitor satisfactions of the plants on display, environments of pedestrian road and facility of each theme garden by conducting a survey of visitors to Jade Garden. The 400 data including 100 copies per theme garden were used for statistical analysis. The statistical techniques used in the survey analysis include multi-regression analysis, t-test, and analysis of variance(ANOVA). As a result of the analysis, most of theme gardens tended to have the greatest impact on the satisfaction of the plants on display and the lowest level of facility satisfaction. According to detailed factors analysis of the satisfaction of plants on display satisfaction of plant diversity and the method of plant display were most affected in most of the theme gardens. Among them, promoting the satisfaction of plant diversity is necessary to plant various species, but in case of Ginkgo Maze Garden, a type of tree community as one tree(Ginkgo biloba), the satisfaction of plants diversity did not show a rising-up value. Therefore, it was confirmed that the appropriate degree of plants diversity depends on the theme or environment of the garden. In the case of the pedestrian-road-satisfaction, the width of the pedestrian road was the most affected, It was analyzed that whether the point of intersection can be easily available during peak season has a significant impact on the satisfaction of visitors. In the case of facility satisfaction, it was analyzed that the presence of rest and convenience facilities had the most direct influence on visitors, so the facility diversity had the greatest influence. Therefore, it is necessary to more systematically categorize and consider the influential detailed factors such as plants diversity and methods of plant display, width of pedestrian road and facilities diversity for the management and development of the arboretum.

The purpose of this study is to find out the effect of recovery from psychological stress when watching plants indoors. As an instrument of measurement of psychological stress, Galvanic Skin Resistance(GSR) has been used because it has been convenient to read a psychological sign without a medical sense and an instrument. In order to make the conditions of stress and recovery, video programs have been made, and especially, the video program of recovery has consisted of three types-- types 1 of watching plants in a botanical garden, type 2 of watching very bush street, and type 3 of closing eyes naturally. The two groups of normal and the mentally handicapped persons have been participated in this experiment to compare the effect of recovery. As the result of this test, the rate of stress relief has been maximumly effected by watching the video program of plants. Between the two groups the recovery of stress has had better effects on the mentally handicapped than the normal one. And also it shows that the circumstances of emotional refinement is led by having plants in indoor. The result of this test has been turned out to be highly useful. It is desirable that a indoor worker, staying for a long time, contact with plants visually to keep healthy mental conditions. This study suggests that the surrounding conditions or the settings of circumstances play an important role for the emotional refinement of the groups of mentally han야capped persons as well as the normal person.

This study analyzed the factors affecting urban residents' expectations and participation in community gardens to present basic data of guidelines for community garden management. Urban citizens valued the necessity of community gardens overall, especially residents with outdoor gardens. The experience of private gardens was important in perceiving the need for community gardens, which are public spaces. The creation of community gardens had high expectations for social aspects such as improving quality of life, health promotion, and community revitalization. In particular, residents living in individual housing have high expectations for revitalization of the community, and community gardens can be a mediator for forming and maintaining local communities. Through this, the citizens' perception on the role and function of the garden as a community space could be examined. Expectations for quality of life, health promotion, and community revitalization are factors affecting the necessity of community garden. Participation was high in the creation and management of the community garden, and the necessity of community gardens, expectation for community revitalization, and expectation for environmental purification are factors that affect participation in the management of community gardens. The amount of donations that the residents are willing to pay for community garden management was KRW 75,222 /year on average. Overall, residents with higher need for community gardens and higher social expectation showed higher participation. Urban citizens have high expectations for community gardens, and they perceive the importance of social aspects more than personal aspects such as community revitalization and quality of life. As a strategy for increasing community involvement, it is necessary to set up the processes, determine participants' composition and roles, and establish a system to promote participation. Considering welfare aspects such as community revitalization and improvement of residents' quality of life, motivation and administrative support for participation in the creation and management of community gardens will serve as important factors.

This study was carried out to investigate the growth responses of medicinal plants such as Glehnia littoralis, Cryptotaenia japonica, Angelica gigas, Reynoutria japonica, Saururus chinensis, Houttuynia cordata, Ligularia fischeri, and Aralia cordata under 70%-shading and full sunlight conditions on a rooftop condition using artificial soil as a growth media. Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordata showed better growth on plant height, leaf length, leaf width, petiole length and leaf number under full sunlight conditions on a rooftop condition. Cryptotaenia japonica and Houttuynia cordata had high value of Hunter's a (red-green) under full sunlight, while had lower value of L(lightness) and b(blue-yellow) than those of 70% shading condition. As an index of plant stress response, Glehnia littoralis, Reynoutria japonica, Houttuynia cordata, Ligularia fischeri showed Fv/Fm values 0.79~0.84 under full sunlight in August, indicating low stress on plant growth. Therefore they seemed to be suitable medicinal plats for rooftop conditions. Ligularia fischeri and Reynoutria japonica showed better growth under 70% shading treatment in August, while showed high growth response under full sunlight conditions in September. The 70% shading treatment was effective for the growth of Angelica gigas, Reynoutria japonica, and Aralia cordata. Angelica gigas and Reynoutria japonica, however, showed better plant growth under full sunlight during summer. The results showed that Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordat seemed to be suitable medicinal plants for rooftop garden where there is a full sunlight condition.

This study conducted a flora survey in the areas of Mt. Sambong (282m) and Mt. Jaung (263m), located in Paju-si, Gyeonggi-do. A total of 434 taxa, including 6 forms, 34 varieties, 11 subspecies, 383 species, 271 genera, and 94 families, were surveyed in the two mountain areas. The ferns were identified as 24 taxa from 10 families, the gymnosperms as 8 taxa from 2 families, the dicotyledonous plants as 322 taxa from 73 families, and the monocotyledonous plants as 80 taxa from 9 families. Five taxa, including Salix koriyanagi, Cimicifuga heracleifolia, Forsythia koreana, Paulownia coreana, and Hemerocallis hakuunensi, were identified as the Korean endemic plants. Eight taxa, including Cimicifuga heracleifolia, Tylophora floribunda, and Iris minutiaurea as Vulnerable species, andAristolochia contorta, Viola diamantiaca, Lithospermum erythrorhizon, Lilium distichum, andArisaema heterophyllumas Least Concern species, were designated as rare and endangered plants designated by the Korea Forest Service. The invasive alien plants were 40 taxa, including Rumex crispus, Phytolacca americana, Cerastium glomeratum, Silene armeria, Chenopodium album, Chenopodium ficifolium, Magnolia obovata, Potentilla supina, Amorpha fruticosa, Medicago sativa, Robinia pseudoacacia, Trifolium repens, Euphorbia supina, Hibiscus trionum, and Oenothera biennisaccounting for 9.2 percent of the 434 taxa of the surveyed plants. As this area is a mountainous area close to settlement facilities, it is believed that ecological preservation measures and measures of specialized plants should be implemented.
