This study was carried out to suggest the baseline data necessary for vegetation restoration by naturalness assessment of riverine wetland within stream corridor. We selected stream reach both of near nature and urbanized by Nonsan stream and Hongchun river as experimental site. Composition of vegetation community and land use pattern between two sites indicated considerable difference, which imply for many different watershed property and process disturbed each other at river ecosystem. Naturalness of the sampled reaches showed that near nature is in better condition for riverine wetland than urbanized of all two sites. However, the prevalence index of Hongchun river within its natural state was lower than that of Nonsan stream, because the index included some vegetation communities occurred at upland fringe and bank slope. In conclusion assessment system using prevalence index would be considered an effective method for evaluating of natural states of riverine wetland.

This study aims to develop the diagnostic evaluation method of the riverine ecobelt for construction, conservation, and maintenance of the riverine ecobelt. The value indices in the proposed evaluation method are composed of total 5 fields and 19 elements. The 5 fields are flood control, environmental function, growth of plants, ecobelt function, and restoration potential. Flood control field is composed of total 3 elements such as length, width, and density of green area. Environmental function field is composed of 4 elements such as park use, landscape boundary and edge, microclimate control, non-point pollution control. Growth of plants field is composed of 6 elements such as species composition, forest height, stratum structure, vine plants, plant vitality, and succession of plants. Ecobelt function field is composed of 4 elements such as longitudinal connectivity, lateral connectivity, in-stream forest or habitat, roads on bank top. Restoration potential field is composed of 2 elements such as landform and land use of the immediate vicinity. The score system ranging 1~4 was adopted. The weighting parameters of elements were unified with each other. The final grade system ranging 1~5(1: very good~5: very bad) was adopted, and the final grade was evaluated by the mean values of each field. According to the test application of the diagnostic evaluation method of the riverine ecobelt, the final grades showed effectively the real condition of each site.

This paper presents a variational equality formulation by Providing new dynamic route choice condition for a link-based dynamic traffic assignment model. The concepts of used paths, used links, used departure times are employed to derive a new link-based dynamic route choice condition. The route choice condition is formulated as a time-dependent variational equality problem and necessity and sufficiency conditions are provided to prove equivalence of the variational equality model. A solution algorithm is proposed based on physical network approach and diagonalization technique. An asymmetric network computational study shows that ideal dynamic-user optimal route condition is satisfied when the length of each time interval is shortened. The I-394 corridor study shows that more than 93% of computational speed improved compared to conventional variational inequality approach, and furthermore as the larger network size, the more computational performance can be expected. This paper concludes that the variational equality could be a promising approach for real-time application of a dynamic traffic assignment model based on fast computational performance.

The Highway Capacity Manual(HCM) suggests estimating the average green time for the performance evaluation of the traffic actuated operation and Provides the average green time estimation model. However, the model provides with much room for improvements. This document proposes a new analytical model that overcomes the shortage of the HCM model. The average green times estimated by the HCM model and the proposed model were compared. A computer program using the proposed model was coded for the study, while the ACT348 program was used for the implementation of the HCM model Through the comparison study based on the 1,196 hypothetical simulation data surrogating field data, it was found that the average green times estimated by the proposed model yields much nicer one-to-one linear relationship to the simulation results than the ones from the HCM model in both exclusive-only and shared-permitted cases. The R2 values of the proposed and the HCM models with those cases are 0.90 and 0.56, and 0.86 and 0.57, respectively.

The purposes of this study are to apply species distribution modeling in urban management planning for habitat conservation in non-urban area and to provide a detailed classification method for management zone. To achieve these objectives, Species Distribution Model was used to generate species richness and then to compare with the results from land suitability assessment. 59 species distribution models were developed by Maxent. This study used 15 model variables (5 topographical variables, 4 vegetation variables, and 6 distance variables) for Maxent models. Then species richness was created by sum of predicted species distributions. Land suitability assessment was conducted with criteria from type I of "Guidelines for land suitability assessment". After acquiring evaluation values from species richness and land suitability assessment, the results from these two models were compared according to the five grades of classification. The areas with the identical grade in Species richness and land suitability assessment are categorized and then compared each other. The comparison results are Grade1 10.92%, Grade2 37.10%, Grade3 34.56%, Grade4 20.89% and Grade5 1.73%. Grade1 and Grade5 showed the lowest agreement rate. Namely, development or conservation grade showed high disagreement between two assessment system. Therefore, the areas located between urban, agriculture, forest, and reserve have a tendency to change easily by development plans. Even though management areas are not the core area of reserve, it is important to provide a venue for species habitat and eco-corridor to protect and improve biodiversity in terms of landscape ecology. Consequently, adoption of species richness in three levels of management area classification such as conservation, production, planning should be considered in urban management plan.

In this study, we predicted species distributions in Mt. Inwang and Mt. An as preceding research to build ecological corridor by considering connectivity of habitats which have been fragmented in the city. We analyzed species distributions by using Maxent (Maximum Entropy Approach) model with species presence. We used 23 points of mammals and 15 points of Titmouse (Parus major, P. palustris, P. varius) as target species from appearance points of species examined. We build 4 geography factors, 4 vegetation factors, and 2 distance factors as model variables In case of mammals, factors that affected species distribution model was Digital Elevation Model(DEM, 34%) followed by Distance from edge forest to interior (24.8%) and Species of tree (10%). On the other hand, in case of Parus species, factors that affected species distribution model were DEM (39.6%) followed by distance from road (35.4%) and Density-class (8.2%). Therefore, birds and mammals prefer interior of mountain, and this area needs to be protected.

The 4-part series of , the 6-part series of , the 7 part-series of , and the 6-part series of differ in terms of their themes, although each one of them focuses on Asia. By winning prominent prizes around the world, these documentaries produced by the 'Insight Asia' Project Team of the Korea Broadcasting System (KBS) were affirmed of their competence in producing quality material. The purpose of Insight Asia Project was to improve the quality of KBS documentaries, and to make them competitive in the world market, Europe in particular. The specific goal 'Insight Asia' Team set for itself was to produce, in 5 years' time, documentaries of equal caliber to the (pre-Murdoch) National Geographic and the BBC. Unfortunately, the "Korean Wave," which was once active in the drama genre, was in stagnation at the time the team was being launched. As a result, KBS shifted refocused on documentaries as its driving force and provided detailed minute plans of action. However, the 'Insight Asia' Project was suspended abruptly in its fourth year, after a change in management in the network, and a discussion or evaluation on 'Insight Asia' Project never occurred. This study's objective is to retrace how the project 'Insight Asia' had been developed, and to clarify its meaning with respect to the KBS's globalization project. For this study, producers who participated in the project were interviewed.

This study was carried out to find the prototype of the rear garden in Changdeok Palace during King Jungjo's reign through Gang Sehwang's "Record of Strolling with King in the Forbidden Garden", and the site of this study included the whole areas of Ongnyucheon(玉流川), Mansongjeong(萬松亭), Mangchunjeong(望春亭), Jondeokjeong(尊德亭), Pyemwoosa and Taichungmun(太淸門). The characteristics of the area of Ongnyucheon described in Record of Strolling with King in the Forbidden Garden was the shape of Wiyiam expressed three-dimensional mountain such as the fence surrounding Soyojeong(逍遙亭) and the painting techniques of Fu Pi' ts'un and pond in front of Taegeukjeong(太極亭). The pond in front of Taegeukjeong(which was described by Gang Sewhang) is also identified in Donggwoldo(東闕圖) and this study judged that the pond was removed during the maintenance process of Ongnyucheon, where was scheduled as the place of entertainment when Chinggyong-Yesik(稱慶禮式: Royal court rites) was held to celebrate the 40th anniversary of King Gojong's reign. The characteristics of the whole area of Mangchunjeong where was the attraction point for flower viewing in the forbidden garden was surrounded by the sculptured fence, and Mangchunjeong which was hexagonal structure was located in the inside of the structure on both sides of the main building. The cornerstone was carved with white jade. Also a corridor assumed as Chunhyanggak(天香閣) was adjacent to Mangchunjeong. Gang Sehwang confirmed the space organization appeared in Donggwoldo by describing the attached building of Pyemwoosa, Taichungmun, and surrounding fence in detail.
