The results of tracking the symbolism of plants in the introduction factors of Sokhwa(folk painting) are as the following. 1. The term Sokhwa(俗畵) is not only a type of painting with a strong local customs, but also carries a symbolic meaning and was discovered in "Donggukisanggukjip" of Lee, Gyu-Bo(1268~1241) in the Goryo era as well as the various usage in the "Sok Dongmunseon" in the early Chosun era, "Sasukjaejip" of Gang, Hee-mang(1424~1483), "Ilseongrok(1786)" in the late Chosun era, "Jajeo(自著)" of Yoo, Han-joon(1732~1811), and "Ojuyeonmunjangjeonsango(五洲衍文長箋散稿)" of Lee, Gyu-gyung(1788~?). Especially, according to the Jebyungjoksokhwa allegation〈題屛簇俗畵辯證說〉in the Seohwa of the Insa Edition of Ojuyeonmunjangjeonsango, there is a record that the "people called them Sokhwa." 2. Contemporarily, the Korean Sokhwa underwent the prehistoric age that primitively reflected the natural perspective on agricultural culture, the period of Three States that expressed the philosophy of the eternal spirits and reflected the view on the universe in colored pictures, the Goryo Era that religiously expressed the abstract shapes and supernatural patterns in spacein symbolism, and the Chosun Era that established the traditional Korean identity of natural perspective, aesthetic values and symbolism in a complex integration in the popular culture over time. 3. The materials that were analyzed in 1,009 pieces of Korean Sokhwa showed 35 species of plants, 37 species of animals, 6 types of natural objects and other 5 types with a total of 83 types. 4. The shape aesthetics according to the aesthetic analysis of the plants in Sokhwa reflect the primitive world view of Yin/yang and the Five Elements in the peony paintings and dynamic refinement and biological harmonies in the maehwado; the composition aesthetics show complex multi-perspective composition with a strong noteworthiness in the bookshelf paintings, a strong contrast of colors with reverse perspective drawing in the battlefield paintings, and the symmetric beauty of simple orderly patterns in nature and artificial objects with straight and oblique lines are shown in the leisurely reading paintings. In terms of color aesthetics, the five colors of directions - east, west, south, north and the center - or the five basic colors - red, blue, yellow, white and black - are often utilized in ritual or religious manners or symbolically substitute the relative relationships with natural laws. 5. The introduction methods in the Korean Sokhwa exceed the simple imitation of the natural shapes and have been sublimated to the symbolism that is related to nature based on the colloquial artistic characteristics with the suspicion of the essence in the universe. Therefore, the symbolism of the plants and animals in the Korean Sokhwas is a symbolic recognition system, not a scientific recognition system with a free and unique expression with a complex interaction among religious, philosophical, ecological and ideological aspects, as a identity of the group culture of Koreans where the past and the future coexist in the present. This is why the Koran Sokhwa or the folk paintings can be called a cultural identity and can also be interpreted as a natural and folk meaningful scenic factor that has naturally integrated into our cultural lifestyle. However, the Sokhwa(folk paintings) that had been closely related to our lifestyle drastically lost its meaning and emotions through the transitions over time. As the living lifestyle predominantly became the apartment culture and in the historical situations where the confusion of the identity has deepened, the aesthetic and the symbolic values of the Sokhwa folk paintings have the appropriateness to be transmitted as the symbolic assets that protect our spiritual affluence and establish our identity.

Recently interactive water fountains are gaining popularity in making public facilities in South Korea. The total number of interactive fountains is rapidly growing at the rate of >50% annually. In this study, we performed quantitative microbial risk assessment to estimate infection risks in children by Legionella spp. while playing in interactive fountains. The exposure dose for a given concentration of Legionella in water was calculated using water-aerosol partition rate of Legionella, exposure duration, inhalation rate, and deposit rate of aerosols in the lungs following inhalation. The dose was converted to infection risk by using the dose-response function developed for L. pneumophila. High weight and/or old children, i.e., 12-year children, running around in fountains were the highest risk group by showing >0.05 infection probability for fountain waters containing ${\geq}10^4$ CFU/L Legionella. The result supported the current guideline by Korea Centers for Disease Control and Prevention, which permits use of water with < $10^3$ CFU/L Legionella cells for all purposes. However, the results still warrant further evaluation of the guideline to accommodate risks for children because the dose-response relationship in the model was developed for healthy adults. Further risk assessment studies need to be conducted by employing dose-response model for children who generally carries weaker immune system than adults.

급속한 산업화로 인한 오염물질의 증가와 생물서식처의 감소는 수자원과 생태계를 위협하고 있다. 국내의 경우 수자원의 질을 개선하기 위해 '90년대 초부터 하수처리시설 등의 저감시설을 대폭 확충하였으나 현재까지 팔당호 등 주요상수원이 목표수질에 못 미치고 있으며 그 원인은 유입오염물질의 $22{\sim}37%$를 차지하는 비점오염원으로 지목되고 있다. 또한 생태.경관적 가치가 높은 수변지역은 각종 개발로 생물서식처가 급속도로 감소하여 종 다양성 보전 측면에서 대책마련이 시급한 실정이다. 이와 유사한 상황에 직면한 선진외국에서는 '하천회랑(river corridor)' 또는 '토양 및 생태시스템을 포함하는 수역과 육역의 점이(漸移)지대'를 의미하는 이른바 '수변완충지대(Riparian Buffer Zones)'의 오염정화 및 생태조성 효과 등의 연구를 통해 효율적 조성방안을 제시하고 있으며 다양한 형태로 현장에 적용하고 있다. RBZs의 일반적인 기능으로는, 유사나 오염물질의 여과 및 차단(필터링 효과), 영양염류의 저감, 하천변 식생을 통한 수자원의 정화 및 강턱의 안정화, 홍수로 인한 하천침식의 방지, 수변 생물 서식처 제공, 수변 그늘 제공에 의한 수온상승 방지, 심미 교육 위락 공간 제공 등이다. 본 연구에서는 외국의 RBZs(Riparian Buffer Zones)가이드라인을 참고하여 국내실정에 맞는 파일럿 규모의 시험완충지를 설계 및 조성하였다. 시험완충지는 남한강 연안에 초본류, 갈대류, 관목류, 자연식생, 혼합식생 등 5가지 'dry biotope'형태로 설치하여 1년간 계절별로 운영하였다. 또한 실험의 정량화와 다양한 조건변화를 위해 차수막, 위어, 유량.농도 조절장치, 라이시미터 등 보조시설을 설치하였고, 정기적인 모니터링을 실시하였다. 조사결과 외국사례를 살펴보면 RBZs의 적정 폭은 수질정화기능의 경우 $15{\sim}30m$, 생태서식처 기능은 최소 90m이상으로 제시되며, 시험완충지의 수질정화효과는 SS, T-N, T-P, TOC의 평균저감율이 각각 50%이상으로 나타났다. 식생모니터링 결과, 환삼덩굴 등 우점종의 잠식속도는 약 15일이며 갈대와 갯버들의 경우 우기시 인공목책호안과 동일한 침식방지 효과를 보이는 것으로 관찰되어 식생의 주기적인 모니터링과 지역 특성에 적합한 우점종 선정이 매우 중요한 것으로 판단된다.

This study analyzes the characteristics of the urban landscape changes as a result of the introduction of private parks among the long-term uncollected urban planning facilities and enables the analysis of the characteristics of the urban landscape changes as a result of the introduction of private parks, and applied to the private park projects. The DSM with its building was established for the quantitative landscape analysis to examine the view ratio using the stacked visible analysis. The analysis showed that Jikdong Park had a high frequency of view from downtown to green due to its location, and that the development project of a private park on park and town boundaries significantly lowered the view ratio. This implies a large degree of damage to the landscape by development projects provided protection of the view as a natural landscape is of value. Chudong Park also saw its view ratio of views from downtown to the hills green area of Chudong Park was much lower than that of Jikdong Park. And it was confirmed that the ratio of view changes due to development projects was small compared to that of Jikdong Park. In other words, although Jikdong Park and Chu-dong Park were developed in a similar scale in terms of the ratio of views, they were subject to significant damage due to their location characteristics. It is also meaningful to note that the degree of change in the landscape resulting from development projects that could not be found in the assessment or review of the existing Landscape Impact. As private parks are introduced in the urban green belt, apartment development is being pushed for at the edge of the green belt. This study is meaningful in that it is derived based on the calculation that the survey results are derived based on the changes in the views on green areas that urban residents may experience as the private park project is carried out, and it should be introduced based on the calculation of the private parks.

Damyang riverine wetland was designated as a wetland protected area in 2004; that is located in the Yeongsan river mainstream. Total 30 phytosociological releves at field studies were classified with 22 vegetation types including of 101 species (unidentified 1 species). Legends of actual vegetation map were separated by 6 types; riparian forest, substitute vegetation, synanthropic vegetation, wet meadow vegetation, open water, an area of wetland vegetation is about 35 % ($386,841.86m^2$). Results of this study area as follows. The plant society of Damyang riverine wetland was conjectured that it was formed by rapidly water environment change with installed weir on the upstream of protected area and operating of Damyang dam on top of the basin. Until recently, the terrace land on the river was used to cultivate, but that would be formed fallow vegetation scenery on riverfront caused by no cultivation after designated protected area. Paspalum distichum var. indutum community designated as invasive alien plant by Korea Ministry of Environment was widely developed and Myriophyllum spicatumunrecorded in the country as newly alien species was discovered in the study zone. The plants as lapped over developing environment for Leersia japonica must be occupied habitat of native plant species having similar niche. The various plant society in Damyang riverine wetland should be developed because of environmental changes, disturbances and damages of stream.

The aim of this study is to suggest guidelines of bicycle lanes in terms of landscape architecture with special reference to Kyongju. The research is mainly based on landscape satisfaction factors analysis regarding 16 variables and 10 slide photos of bicycles lanes. The 43 students of Landscape Department in Kyungpook National University were selected for the research. The major research findings are as follows; 1. Satisfaction degree of 16 variables are assessed in terms of semantic differential scale. The assess group is generally satisfied with variables concerning bicycle lane environment such as $\ulcorner$inclination of the lane (5.2)$\lrcorner$and $\ulcorner$road pavement conditions (5.1)$\lrcorner$. But the group expresses rather low satisfaction degree on the variables related lanes' surrounding landscape such as $\ulcorner$visual variety (3.9)$\lrcorner$, spacious resting place (3.7)$\lrcorner$ and $\ulcorner$variety of facilities (3.1)$\lrcorner$. 2. The level of satisfaction degree regarding 16 variables and 10 photos shows that the male gives relatively higher satisfaction degree than the female group. But there is no statistical significance between the group regarding satisfaction degree of each variable and photo except 4 variables and 2 photos. 3. The assess group gives the highest satisfaction degree on the$\ulcorner$no. 10 slide (6.5)$\lrcorner$ and the lowest on the $\ulcorner$no. 7 slide (2.7)$\lrcorner$. The two photo shows variables of more than 4 points difference of satisfaction degree, such as $\ulcorner$good looking planting threes (4.8)$\lrcorner$, $\ulcorner$enough shadows (4.8)$\lrcorner$ and $\ulcorner$comfortable atmosphere(4.1)$\lrcorner$. 4. $\ulcorner$Aesthetic and amenity factor$\lrcorner$, $\ulcorner$use condition factors$\lrcorner$, $\ulcorner$ike lane environment factors$\lrcorner$, and $\ulcorner$inclination and open view factors$\lrcorner$are the main four factors influencing landscape satisfaction of bicycle lane. Regression model using factor scores for landscape satisfaction degree of bike lane is S(Satisfaction degree)=4.526+1.099(aesthetic and amenity factor)+0.720(use condition factors)+0.486(bike lane environment factors)+0.048(inclination and open view factors($R^2$=0.811).

This study analyzed greenspace structure focused on greenspace areas and vegetation structure for Yanggu, investigated resident attitudes to the greenspace, and explored strategies to improve greenspace functions in a rural region. Woody plant cover was approximately 29% for parks and only 3% for commercial gardens. The amount of planting for Yanggu was poor, as compared with the results of similar studies for urban areas. Trees, of which dbh was below 20cm, accounted for 91% of all trees and the tree-age structure was largely characterized by a young, growing tree population. Based on the analysis of mean importance values (MIV) of woody plant species, only a few were different in dominant species from urban areas. Four species among 10 species with highest MIV in Yanggu were very common species also ranked among 10 in cities. The most dominant species planted in residential and commercial gardens were practical plants such as fruit or edibles. Greenspace covered about 69% of parks, 39% of residential gardens, 37% of institutional gardens, 24% of streets, and 15% of commercial gardens, respectively. Tree planting potential revealed that present woody plant cover can be increased additionally by 6 times in the streets and by 2 times in the residential and commercial gardens. Based on the results of greenspace structure, planting patterns, and questionary investigation, some strategies were suggested to enlarge greenspace including its environmental functions. They included identifying each street section through setting up themes and planting appropriate species, creating multilayered vegetation structures, and promoting planting in bare grounds of gardens and around a buildings for saving energy.

This study examined ecological network change affected by the 2020 invalidation of decisions on urban parks with a focus on Busan. The analyses were conducted to five scenarios using FRAGSTATS. The green space in scenario 1 assuming all development for unexecuted urban park would decrease by 7,339.75 ha compared to scenario 5, which assumes the entire conservation of unexecuted urban parks, and the fragmentation of the ecological space in scenario 1 increased. In scenario 1, 8.06% of the total area of core habitats and 28.23% of connectivity would decrease. However, scenario 3, which assumes the conservation of environmentally sensitive areas of unexecuted urban parks, can achieve 94% of green space and 95.6% of the connectivity of the scenario 5. Scenario 3 has effects similar to scenario 5 in terms of defragmentation. Thus, conservation of environmentally sensitive areas in parks is critical and effective in maintaining ecological networks.
