In Korea, a variety of policies for the regional cultural industry development have been carried out: the promotion policy of cultural industry cluster, the establishment of cultural industry support center, and the construction of cultural industry complex and the supporting works for the cultural research center. The cultural industry has a dual character of the manufacturing industry and the service industry. The cultural industry of Gyeongbuk province is mostly centered upon small manufacturing firms with low value-added. Thus, it is desperately in need of the building-up of the enterprise supporting system. However, it is difficult to expect that private business service finns can be activated. In this sense, local and regional governments seek to establish so called 'the cultural contents support center'. However, it is not clear whether the center is an organization for the production of cultural contents or an agency for the support of cultural contents industry. Also it does not prepare any major functional introduction facilities and performing programs. Most of all, it is necessary to establish a proper orientation that 'the cultural contents support center' must be not an organization for the direct production of cultural contents, but an organization supporting cultural industry by way of providing cultural industry enterprises with what is necessary for the production of cultural contents. Also, a system for the establishment of business fitting support policy that can cover the whole sectors of cultural industry must be prepared. Furthermore, a synthetic support system for the cultural business associated industries centered on specified sectors such as films, edutainment, and storytelling must be constructed. Finally an environment for the creation and inducement of cultural industry enterprises, and for the active participation of enterprises and related groups in the promotion planning and in the policies of cultural industry must be built along with on- and off-line networks.

Since the industrialization in the 1960s, Korea has been expanding its transportation infrastructure, such as building bridges. Owing to bridge construction, studies on stability review have been carried out, and stability-securing technology has been developed. On the other hand, these were applied mainly to the upper part of the bridge, so applications to the lower part are limited. In particular, scour at the bridge pier causes erosion in the riverbed and bridge collapse. Hence, prevention studies and countermeasures are needed. In this study, an empirical formula was developed to evaluate the scour depth of a bridge, which was calculated through multiple linear regression analysis using the hydraulic model study data conducted in previous studies. The formula, which had a value of 0.91, was applied to the model test data that was not used for development to verify the developed formula. When the pier scour depths were compared in 23 cases, the error rate was less than 20% in 16 cases (70%). The empirical formula developed in this study is applicable to pier scour-depth calculations. Further research will be needed to develop a more accurate empirical formula for pier scour-depth calculations, and it is expected to reduce bridge damage caused by scour.

Currently the number of unsold housing is rapid increasing over again in the Seoul Metropolitan area. So this research analyzed effective and possible solutions focus on the potential customers and professionals. There was a research method setting up alternative solutions from the existing researches and the other suggestions though FGI (Focus Group Interview) by professionals. And then it investigated the efficient ways to resolve those problems through Conjoint Analysis. According to the result of this paper, firstly the customers considered 'financial supports', 'self-rescue efforts for construction companies' and 'taxation support' than the other. On the other hand, professionals evaluated 'publicly purchased housing' and 'new housing policies' were more essential solutions besides, both of them recognized the importance of ;financial support'. Secondly there were some ideas that it was necessary to more less control LTV (Loan to Value ratio) and DIT ( Debt to Income) and the LH (Korea Land and Housing Corporation) buy unsold housing. Finally the government and housing association had to manage and intervene the supply of housing within metropolitan area and restrict to building new properties and the construction companies actively provide less strict standard terms and conditions in contract for purchasing housing for instance, the decline of housing sale price or interest-free and so on.

Seokgasan(石假山) is originated in Goryeo, is a Korean traditional technique handed down to Joseon and Seokgasan is the Korean creative culture of gardening by artificial stones, which replicates small artificial mountain of natural landscape in the garden. The object of this study is Seokgasan made by Seong-im(成任), who was a civil minister in Joseon and lived from 1421 to 1484, in his residence located in Inwang Mountain, Hanyang and the purpose of this study is to investigate the historical meaning and symbol of Seokgasan made by Seong-im on the base of the relative old literatures and embody its shape and structure. According to the result of this study on Seokgasan of Seong-im, it can find out some facts as follows; Seokgasan of Seong-im in the early Joseon succeeded to the structural form of Seokgasan of the artificial rock mountain type connected pond, which was made-up firstly in the garden of the Palace of Manwoldae in the Middle Goryeo, and it was called firstly as 'Seokgasan' in the garden of Seong-im's house. Seong-im's Seokgasan in the early Joseon had more concentrated philosophical meanings, including the idea of taoist immortal, than those in the Goryeo dynasty and was be emblematic of an imaginative space. Also there were lots of gardens modeled on the famous mountains and famous lakes in China much the same as the Goryeo dynasty. In addition, there was an exceptional purpose for building Seokgasan which could not be found in the Goryeo dynasty. That was practicality for emotional stability and cure. Seong-im's Seokgasan is record-relics with high value of landscape architecture history, which can identify its historical meanings, shapes and structural frames succeeded from the Goryeo dynasty.

This study identifies a factor structure regarding the criterion of terror awareness by using confirmatory factor analysis. The study provides information whether the criterion fits in the analysis of terror awareness in Korea or not. Data of 176 public officials working at the National Assembly collected in 「Study on the Improvement of Security in the National Assembly Building」(Choi O-Ho and others, 2016) was used in the analysis. Study results showed the fit statistics of 3 questions regarding concern in terror, 5 questions regarding cognition of terror occurrence, 3 questions regarding countermeasure of terror, and 3 questions regarding equipments against terror satisfied the standard. Also, standard regression coefficient exceeded the standard and was shown to be fit. Concern in terror, as a latent variable, was below the standard value of average variance extracted. However, focused validity was secured by obtaining other values fit. This study proceeded distinct validation test to supplement data. The test results showed that the criterion level was fit. Thus, further survey should include questions that are appropriate to measure the awareness of terror based not only on theories and previous studies but also on questions of terror awareness tested in this study. Such development in surveys will support the means of data measurement.

Accurate QPE (Quantitative Precipitation Estimation) and the quality of the rainfall data for hydrological analysis are very important factors. Especially, the quality has a great influence on flood runoff result. It needs to know characteristics of the uncertainties in radar QPE for the reliable flood analysis. The purpose of this study is to present a probabilistic approach which defines the range of possible values or probabilistic distributions rather than a single value to consider the uncertainties in radar QPE and evaluate its applicability by applying it to radar rainfall. This study generated radar rainfall ensemble for the storms by the typhoon 'Sanba' on Namgang dam basin, Korea. It was shown that the rainfall ensemble is able to simulate well the pattern of the rain-gauge rainfall as well as to correct well the overall bias of the radar rainfall. The suggested ensemble technique represented well the uncertainties of radar QPE. As a result, the rainfall ensemble model by a probabilistic approach can provide various rainfall scenarios which is a useful information for a decision making such as flood forecasting and warning.

Over the decades, a lot of studies have dealt with the traffic characteristics and phenomena at a merging area. However, relatively few analytical techniques have been developed to evaluate the traffic flow at the area and, especially, the ramp merging capacity has rarely been. This study focused on the merging behaviors that were characterized by the relationship between the shoulder lane flow and the on-ramp flow, and modeled these behaviors to determine ramp merge capacity by using gap acceptance theory. In the process of building the model, both an ideal mergence and a forced mergence were considered when ramp-merging vehicles entered the gap provided by the flow of the shoulder lane. In addition, the model for the critical gap was proposed because the critical gap was the most influential factor to determine merging capacity in the developed models. The developed models showed that the merging capacity value was on the increase as the critical gap decreased and the shoulder lane volume increased. This study has a meaning of modeling the merging behaviors including the forced merging type to determine ramp merging capacity more precisely. The findings of this study would help analyze traffic phenomena and understand traffic behaviors at a merging area, and might be applicable to decide the primary parameters of on-ramp control by considering the effects of ramp merging flow.

This study dealt with developing an accident model for rural signalized intersections with random parameter negative binomial method. The limitation of previous count models(especially, Poisson/Negative Binomial model) is not to explain the integrated variations in terms of time and the distinctive characters a specific point/segment has. This drawback of the traditional count models results in the underestimation of the standard error(t-value inflation) of the derived coefficient and finally affects the low-reliability of the whole model. To solve this problem, this study improves the limitation of traditional count models by suggesting the use of random parameter which takes account of heterogeneity of each point/segment. Through the analyses, it was found that the increase of traffic flow and pedestrian facilities on minor streets had positive effects on the increase of traffic accidents. Left turning lanes and median on major streets reduced the number of accidents. The analysis results show that the random parameter modeling is an effective method for investigating the influence on traffic accident from road geometries. However, this study could not analyze the effects of sequential changes of driving conditions including geometries and safety facilities.
