The Sin-Wol filtration plant was an urban infrastructure and off-limits to the public. It is recreated as a representative experiential theme park in the southwest area. It has not only provided places to relax, but has made a new model of urban park by reusing advantages. The current lack of easy access into the park area almost isolates it like a green island. The neighborhood surrounding the park does not have many physical connections to the park to be able to use it. By connecting the surrounding communities with numerous access points into the park and linking the hiking trails and bike paths, the city's need for open space and recreation would be far better satisfied than before. This would allow for the use of the valuable assets of the existing forest and open space.

Baekdudan has 670km long within South Korea, so the study for detail vegetation characteristics is needed. In this study, we surveyed the plant community structure from Daetjae to Baekbongryung for the next restoration and management plan. We designated 40 quadrats ($10m{\times}10m(100m^2)$ for this study. As a result of TWINSPAN, plant community separated 8 different communities such as Abies koreana comm., Pinus densiflora comm., Quercus mongolica comm. and Larix kaempferi comm. etc. Abies koreana comm. and Pinus densiflora comm. which is mainly located in the mountain ridge and near rocks are needed avoidance from the competition with Quercus mongolica comm. The possibility of atrophy of these communities is to be high, the protection is needed. Species diversity index was between 0.8046~1.1283. Most communities have multi-layer structure and have the ecological value of protection.

붉가시나무는 기후변화에 따라 분포 확산이 예측되고 목재로서의 이용가치가 증가하고 있다. 본 연구는 국내에서 붉가시나무의 자원량 및 생육환경을 파악하기 위하여 국내 분포 및 자생지의 식생구조를 분석하였다. 분포 범위 조사 결과, 제주도를 비롯한 남해안의 도서지역에 주로 분포하는데, 제주도 남부지역 약 200~800m에 분포하며 가거도, 완도, 진도 등에 주로 분포하였다. 지역별 자생지의 입지분석 결과, 교목층의 수고는 제주도에서 17.3m로 가장 높고 가거도의 경우 11.3m로 가장 낮았다. 또한 가거도 자생지의 경우 노출암 비율 70.7%, 평균 경사도 약 $30^{\circ}$로 경사가 매우 급하고 토양층이 가장 빈약하였다. 반면, 제주도에서는 계곡 사면이나 완만한 경사의 산록지대에 주로 분포하였다. 자생지의 식생구조를 파악하기 위하여 수종별 평균중요도지수를 산출한 결과, 교목층에서는 붉가시나무가 가장 높았다. 아교목층의 평균중요도지수는 제주도, 완도, 진도 자생지의 경우 동백나무가 각각 150.93, 83.54, 91.38로 가장 높았는데 이는 동백나무의 밀도가 상대적으로 높았기 때문이다. 반면 가거도 자생지에서는 붉가시나무의 평균중요도지수가 66.55로 가장 높게 산출되었다. 자생지 내 수종의 흉고직경에 따른 수고의 분포는 제주도, 진도, 완도 자생지의 경우 붉가시나무와 기타 수종이 전체 층위에서 고르게 분포하였지만 가거도 자생지에서는 상층일수록 경쟁 종없이 단일종이 분포하는 단순림으로 나타났다. 이 같은 단순림에서는 일시적인 교란에 의해 상층 개체가 없어지면 안정적으로 후대 개체를 생산할 수 없기 때문에 숲 가꾸기와 같은 적극적인 조절이 필요한 것으로 판단된다. 종다양도지수 분석결과, 층위가 높을수록 균재도가 낮게 나타났다. 이와 같은 연구결과는 붉가시나무림의 조성이나 안정적 유지 등 인위적 조절을 위한 기초 자료로 활용 할 수 있을 것으로 판단된다.

Agricultural landscapes in Korea comprise a large cultivation area of rice paddies, other crops, and forests which surround the cropland and the farmers' residential village. The forests in this agricultural landscape play important roles as ecological corridors and refuges for plants and animals in this agroecosystem. The present study investigated the spatial and temporal diversity patterns among these components of the agroecosystem to provide baseline data that describes how fauna change in the studies system. Insect sampling was conducted at four sites in two regions, Chungcheong (Ockcheon and Geumsan) and Jeonnam (Younggwang and Haenam), from March to August of 2014, using an UV light trap for moths and five pitfall traps for beetles. Beetles comprised 225 species and 2,457 individuals in 35 families, while moths consisted of 141 species and 403 individuals in 17 families. Beetles showed higher diversity in Chungcheong than Jeonnam, while moths showed no difference in diversity between regions. Forests showed the highest number of species and individuals, followed by orchards and rice paddies. The food preference of beetles showed that forests contained a higher proportion of herbivores, while orchards and rice paddies had a higher proportion of carnivores. Temporal changes in moths in the two regions were synchronous, while those of beetles were nonsynchronous. Moths increased from spring to summer across all habitats, especially in rice paddies during summer. Beetles also increased from spring to summer in orchards and rice paddies, although the beetles in the forests increased in the middle of summer. A detailed and long-term study is needed to reveal the causes of different diversity patterns of taxa among the different habitats within the agroecosystems.

This study is to derive a design alternative to the FECC (Forest Experience Center for Children) that meets the preschooler's preferences. For this purpose, preschooler participation is included in each phase of the FECC, the site perception phase, the deriving design elements phase, and the deriving design alternative phase. In this study, the process of the deriving design alternative phase was carried out with kindergarteners and preschoolers (6, 7 years olds; all 41 students) at Songsan-mulbit FECC in Gwangsan-gu, Gwangju. In order to derive the design alternatives, three detailed design processes (preschooler participation 2 times, researcher analysis 1 time), tool construction, and a preschooler participation workshop were conducted. The results of this study are as follows. First, as a result of the preschooler's design process, 41 designs were drawn, and an average of 7.66 spaces were drawn by each preschooler. The 6-year-old males designed the least (average 6.80 spaces) and the 7-year-old females designed the most (9.0 spaces). The physical and adventure play spaces were most common (38.9% to 48.7%) regardless of gender or age. To analyze the feasibility of the preschooler's design using a base map, the appearance of the physical environmental characteristics (7 items) in the site were analyzed in each of the 41 designs. As a result, the environmental characteristics were apparent a total 72 times overall. Similar environmental characteristics appearing more than once were apparent in 87.8% (26 designs) of designs. Second, three design alternatives were derived: APS- types (intensive planning of active play facility spaces) was presented in 15 designs, NS-types (planning focused on nature spaces) was presented in 14 designs, and SPS-types (planning focused on static play facility spaces) were presented 12 designs. Third, NS-type, which were finally selected through a preference assessment (5-point scale) and a comparative assessment of the three alternatives, has mainly natural spaces (forest space, forest path, shelter, natural exploration space, and ecological pond) and active play facility spaces, water play space and soil (sand) play spaces was appropriately designed. Therefore, the NS-type was analyzed as the design alternative that can fully accomplish all types of cognitive development through developed through play (functional play, constructive play, dramatic(symbolic) play).

Baekdudaegan field survey has been proposed and presented as a various plan such as field survey analysis, management and restoration plan, etc. Whereas, the concerns of the Jeongmaek has increased continuously, nevertheless there is no research of present condition for Jeongmaek. This paper is to contribute to suggest for management and restoration as a basic study of vegetation structure in Yongso valley. We set up 30 plots($100m^2$) to verify the vegetation structure. As a result of classification analysis used by DCA, the type of 5 communities i.e. Pinus densiflora community, Betula schmidtii community, Populus maximowiczii community, Quercus mongolica community, Q. variabilis community were the most representative of Yongso valley vegetation communities. P. densiflora community was mainly distributed in the ridge of mountain, ridge of steep slope and stony area. In that reason, they avoid to compete with B. schmidtii community and Q. spp. community. In addition, the appearance of Rhododendron micranthum was mainly characteristics in the P. densiflora community. Species diversity indices(H') of groups were ranged from 0.7914~0.9942, the tree ages were 30~115 years. According to these results, the forests of Yongso valley not only form muti-layer vegetation structures but also have a great ecological value for protection and preservation.

Changes of the species diversity and development of vegetation structure during abandoned field succession after shifting cultivation were investigated in Pyoungchang, Gangwon-Do, Korea. The height of top layer tended to increase rapidly during the earlier successional stages and stabilize in the later successional stage. The heights of top layer in the 10, 20, 50 and 80 year old-field were 4, 9, 18 and 18 m, respectively. In this region, thirty five year after abandonment need for the development to the normal forest formed by 4 stratum structure, tree, sub-tree, shrub and herb layer. Among the vegetation values, Ivc showed a tendency to increase logarithmically, and Hcl a tendency to increase linearly during abandoned field succession. Species diversity showed the peak in mid-successional stages ($10{\sim}20$ year old-field) and declined slightly thereafter. Species diversity was correlated closely with the species richness than the evenness. The most woody species established in the earlier stage ($2{\sim}6$ year old-field) and turned over their dominance step by step during succession. These results support the IFC model proposed by Egler (1954).

The purpose of this study is to clarify the structure of healing coded through transcriptional activity in the poem of Cho Ji-Hoon in the aspect of literary therapy. In particular, the search for how the codes of emotion are activated through neurophysiologic synapse. The variation of emotional codes developed in Cho Ji-Hoon's poem is in line with the encoding of literary therapy. Emotions emanating from poetic statements stimulate the transition of new emotions and activate emotions of healing. Cho Ji-Hoon's poem fuses emotions through the floods of various poetic transitions. It is then forming an overall healing forest. The healing content is discussed by the structure of transition, and all the structures are linked to the contents of healing. It is a greater part of sad lyricism by the action of descent and ascension, and green aesthetics of the leaves. In the future, if Cho Ji-Hoon's research on poetry is activated, we will be able to meet genuine stories about his natural and literary healing life.

This study sought to analyze changes in the vegetation structure and species diversity indices in the Abies koreana forest in the Yeongsil area of Hallasan Mountain and establish basic data for Long-Term Ecological Research (LTER). The results show that the number of woody plants per 1ha has increased by 804 (45.1%) from 1,781 to 2,585 individual plants, whereas the number of live A. koreana did not change much with 796 individual plants. The number of dead tree plants, however, jumped by 807 (82.2%) from 982 to 1,789 plants. With other tree species, the number of live individual plants increased by 807 (82.2%) from 982 to 1,789 plants, whereas the number of dead plants increased by 31 from 10 to 41 individual plants. Results of the average importance index analysis show that the number of A. koreana decreased, while the number of Weigela subsessilis, Rhododendron yedoense for. poukhanense, and Magnolia sieboldii increased. The species diversity index increased by 6.7% as per the maximum level in the upper layer and by 7.2% in the lower layer, respectively. Results of the stem morphology analysis show that the number of AS type was highest with 700 individual plants among A. koreana, while their distribution by type shifted from AS>AL>DS>DB to AS>DS>AL>DB. As for other species, the AS type was most abundant with 1,580 individual plants, while their distribution by type shifted from AL>AS>AF>AB to AS>AL>AB>AD. The number of newly sprouted tree plants has increased from 420 in 2014 to 453 in 2016. Of the individual plants that were alive in 2014, 23 were found dead and 33 individual plants younger than 3 years old have been newly added to the group. The number of deaths after 2014 was highest among the 2 years olds, whereas the number of 2 years olds that sprouted in 2014 was highest among the newly sprouted tree plant group. In the A. koreana forest in Yeongsil, the density of other species was rising rapidly with the exception of the dead and live A. koreana. The occurrence of new tree plants is decreasing rapidly, thereby confirming the rapid change in the area's vegetation structure. Therefore, there is a need for continuous long-term ecological research to monitor vegetation change. It can also be used as a basic data for efficient restoration research.

Two distinct spider communities were studied in the crowns and ground surfaces of pine plantations at Mt. Ungilsan, Kyonggi-do using pitfall traps and knock-down by spraying of an insecticide (D.D.V.P.) to sample spiders. There were 34 species of 11 families in the ground community and 41 species of 15 families in the crown community, with only 9 species being collected in both. Wandering spiders comprised 78.5% of the crown community and 90.8% of the ground community. Guild abundance and the most abundant families were distinctly different in the two habitats: agile hunters (Salticidae:32.4%) and nocturnal hunters (Clubionidae:19%) in the crown, runners (Lycocidae:32.8%) and nocturnal hunters (Gnaphosidae:31.2%) in the ground. Dominant species were Clubiona jucunda (Karsch) and Mymarachne japonica (Karsch) in the crown, while in the ground they were Pardosa laura Karsch and Gnaphosa silvicola. Species diversity(H ) had peaks in May, July and November in the ground community, while in the crown community peaks were in June and September. The seasonal trends of species diversity (H ) were due mainly to differences in the number of species and the numbers of individuals collected at each sample date rather than to differences in equitability among species. Spier guilds and dominant species have different seasonal patterns based on the temporal differences in prey availability in the two communities and the reduction of temporal overlap.
