The Nakdong-Jeongmaek extends north and south from Taebaek-si of Gangwon-do to Busan metropolitan city and includes a wide range of forest zone from temperate to the warm-temperature forest. The purpose of this study was to analyze the vegetation structural characteristics of the Quercus mongolica-dominant community, which was distributed in the largest area in Baekdudaegan and Jeongmaek, by region and communities in the Nakdong-Jeongmaek. For the study, a representative 6 sites were selected: Baekbyeongsan, Chilbosan, Baegamsan, Unjusan, Goheonsan, and Gudeoksan. The survey of the 6 sites showed that the canopy had over 85% the importance percentage of Quercus mongolica. In the understory, Rhododendron schlippenbachii, Fraxinus sieboldiana, etc. were located and Fraxinus sieboldiana, Lespedeza maximowiczii, Tripterygium regelii and so on were found in the shrub. The importance percentage of 4 communities of Quercus mongolica, which were separated by TWINSPAN, in the canopy was more than 80%, and the dominant species in the understory and shrub were the same. Currently, Quercus mongolica has been identified as the understory following the canopy, and the Quercus mongolica-dominant community is expected to continue unless there are external factors. In the temperate forest regions in Korea, Quercus spp.and Carpinus laxiflora form the major forest physiognomy in the natural forest state. Based on these characteristics, the Quercus mongolica-dominant community on the ridge of the Nakdong-Jeongmaek is considered to have characteristics of temperate forests in Korea. The Quercus mongolica community is a representative cool-temperate deciduous forest and known as a climatic climax in the upper section of the mountains in the Korean Peninsula. Trees of the same species should be distributed at each layer to maintain the dominant species' status in the canopy's climax forest. Therefore, the Quercus mongolica community is considered the climax forest in the ridge of the Nakdong-Jeongmaek.

This thesis aims to research ways for the regional balanced development of cartoon creation & production environment being centered in metropolitan area in Korean cartoon industry which has rapidly changed since 2013. As a cartoon can not only be produced with relative lower production cost comparing to those of other cultural contents industries, but also can be produced only if the minimal requirements for cartoon production is prepared, so the cartoon is a field that the decentralization can be accomplished very easily. Currently, most cartoon-relevant companies and cartoon promotion institutions are located in Seoul an Bucheon, etc. However, cartoon artists live nationwide, and even cartoon artists producing their works abroad are reached to a significant number. In some regions like Daejeon, Busan, Suncheon and Gyeongbuk (Gyeongsangbuk-do), there have been appeared full-scale movement to construct regional cartoon creation & production centers since 2015. This thesis aimed to investigate each region's movement to construct cartoon creation & production center with oversea cases, and to check how such movement could be balanced and harmonized with each region's unique features. First of all, this thesis analyzed the status quo of government's policy nurturing the cartoon industry. Korean government's cartoon-promotion policy around the axis of the Cartoon Industry's Mid.Long-Term Development Plan has been developed around the Korea Creative Content Agency and the Korea Manwha(cartoon) Contents Agency in Bucheon, but as the webtoon industry has rapidly grown up, the necessity for building a cartoon promotion institution in each region has been raised since 2015. With the establishment of 4th Cartoon Industry Mid.Long-Term Development Plan to be executed from 2019, it seems that full-scaled support framework for cartoon regional balanced development should be occupied. For the case of foreign countries, cartoon promotion institutions and relevant events have been developed around regions from early times like San-Diego, USA(Comicon), Angouleme, France(National Image Center), Kyoto (Cartoon Museum), Sakaiminato(Misuki Sigeru Road), Japan gave a lot of implications. In the section of conclusion, this study aimed to suggest the importance of and necessity for establishing a cartoon creation & production center in each region appropriately for the region's identity and characteristics with specific plans. Based on that, this thesis aimed to suggest a vision for cartoon & webtoon industry that regional creation & production system can be settled almost only in the cultural contents industry.

In urban areas, the impermeable area continues to increase due to urbanization, which interferes with the surface penetrating and infiltrating of rainwater, causing most rainwater runoff to the surface, deepening the distortion of water circulation. Distortion of water circulation affects not only flood disasters caused by rainfall and runoff, but also various aspects such as dry stream phenomenon, deterioration of water quality, and destruction of ecosystem balance, and the Ministry of Environment strongly recommends the use of Low Impact development (LID) techniques. In order to apply the LID technique, it is necessary to set a rainwater management target to handle the increase in outflow after the development of the target site, and the current standard sets the rainwater management target using the 10-year daily rainfall. In this study, the difference from the current standards was analyzed through statistical analysis and classification of independent rainfall ideas using inter-event time definition (IETD) in setting the target amount of rainwater management to improve water circulation. Using 30-year rainfall data from 1991 to 2020, methods such as autocorrelation coefficient (AC) analysis, variation coefficient (VC) analysis, and annual average number of rainfall event (NRE) analysis were applied, and IETD was selected according to the target rainfall period. The more samples the population had, the more IETD tended to increase. In addition, by analyzing the duration and time distribution of independent rainfall according to the IETD, a plan was proposed to calculate the standard design rainfall according to the rainwater management target amount. Therefore, it is expected that it will be possible to set an improved rainwater management target amount if sufficient samples of independent rainfall ideas are used through the selection of IETD as in this study.
