This paper is for investigation and analysis of how a visual studio is widely used by domestic broadcasting companies and broadcasting companies' production environment. The history of a visual studio goes back to start of computer graphic. A visual studio is a way to produce a program using graphic sets created by a computer rather than actual setting, and it allows to express beyond limitations of actual studio settings and various imagery visual effects can be created by a computer. A visual studio can create 3-dimensional graphic and these graphics can be inter-locked with actual camera images to make visual spaces for various programs. These flows are aiming to achieve very natural image which is hard to distinguish it is artificially created rather than just to produce programs with simple image synthesis, and this paper analyzes the producing changes of domestic broadcasting visual studios as well as its usage and suggests the idealist direction for developing the production.

Shaking tables are devices for testing structures or structural components models with a wide range of synthetic ground motions or real recorded earthquakes. They are essential tools in earthquake engineering research since they simulate the effects of the true inertial forces on the test specimens. The destructive earthquakes that occurred at the north part of Algeria during the period of 1954-2003 resulted in an initiative from the Algerian authorities for the construction of a shaking simulator at the National Earthquake Engineering Research Center, CGS. The acceleration tracking performance and specifically the inability of the earthquake simulator to accurately replicate the input signal can be considered as the main challenge during shaking table test. The objective of this study is to validate the uni-axial sinusoidal performances curves and to assess the accuracy and fidelity in signal reproduction using the advanced adaptive control techniques incorporated into the MTS Digital controller and software of the CGS shaking table. A set of shake table tests using harmonic and earthquake acceleration records as reference/commanded signals were performed for four test configurations: bare table, 60 t rigid mass and two 20 t elastic specimens with natural frequencies of 5 Hz and 10 Hz.

This study is basically to investigate the possibility of revitalizing the fishing village economy by targeting on trip type, propensity, and awareness of visitors who visited Gogunsan in JeonBuk by applying Blue Amenity. As the result of survey, it showed that visitors in Gosunsan islands generally were satisfied with trip, and they had considerably higher intention of revisit. However, it showed that the improvement and publicity of various travel services including resources and facilities were demanded. In particular, it should pay attention to requirements depending on age and selection of main visitors with reference to revisit, and as the result, the factors having the most important influence on are traffic, and natural scenery, so it is considered that these factors must be maintained to increase the rate of revisit with full of concentration. Besides, it is confirmed that Visitors are unfamiliar with Blue Amenity applying fishing village's own historical cultural resources with reference to preferring islands trip, and they were much concerned about the establishment of tentatively named "regional(urban - fishing village) center" to revitalize the fishing village economy. Moreover it could grasp the tourist industry operated jointly by fishing villages, the pride of town to characterize, advantage in promoting the tourist industry as compared with other regions, and difficulties or recommendations in promoting the tourist industry. And comprehensive investigation of Blue Amenity resources in this region and the measures of improving life environment must be performed in future.

The increasingly high prices for oil, the exhaustion of fossil fuels as well as concern about global warming are driving rapid growth of alternative sources of energy in the world. The active solution for global environment and exhaustion of energy sources is to develop and popularize the technologies to use natural energy such as sunlight, wind, and water. PV(Photovoltaic) modules are efficient devices that has been considered a logical material for use in buildings. Recent advanced BIPV(Building Integrated PV) technology have rapidly made PVs suitable for direct integration into construction in the world. Recently, building has been higher and higher. Tall buildings have many advantages for BIPV such as wide facade area and no shading effect by the surrounding buildings. However. BIPV has not been applied for tall building facade yet. Therefore, the purpose of the research is to develop suitable BIPV for tall buildings and to put these technologies to practical use. Therefore, the purpose of the study is to investigate unification of BIPV to curtain wall to apply BIPV on tall building through research into advanced application of overseas BIPV cases.

Research on construction waste unit was in progress in the 1995 when 'Proper Disposal and Recycling Measures for Construction Waste' was made by the Seoul Development Institute. Such an effort has been made in order to cope with the lack of natural resources in Korea and to utilize the reusable resources. Furthermore, these efforts have also increased due to the improved standing of Korea in the international community. A large number of residential buildings were built in the response to the government's policy by increasing the supply of houses between the 1970's and 1980's. In 2000, more reconstruction and redevelopment was done because of the aged buildings and change of use for those buildings. And the project has been actively promoted until now, which caused a sharp increase in the generation volume of construction waste. In Korea, 8 kinds of construction waste unit, including the standard construction manpower and materials estimation, are introduced. Currently, they provide standards to different building categories and waste properties while for construction sites different standards are applied. This study aims to measure the actual amount of construction waste after sample buildings are dismantled and analyzes the estimation of the waste quantity by using various standard units. Through comparison, this study will figure out the differences among the standard units in order to find out how to apply the standard units properly. Moreover, this research will provide practical measures to apply such units to construction sites.

The Yangdong traditional historic village is a representative village having symbolic historic values and unique combinations of natural, cultural, and social characteristics of a Korean historic settlement environment, which has been protected by Cultural Asset Protection Law since 1984. Now, in spite of its potential diverse powers, national strategies concerning Yangdong village do not have satisfactory direction and results. In consideration of this notion, this paper is designed to find and to understand the current state of Yangdong village. This paper aims to analyze The changes in Yangdong village between 1994 and 2002, and through these comparisons, to diagnose and predict future aspects of Yangdong village. Primary data was collected by questionnaire investigation between 1994 and 2002. The living conditions, production, and consciousness of residents of Yangdong village are utilized as standards of analysis. The final analysis results can be summarized as follows: because of the Cultural Asset Protection Law, noticeable changes have occurred in Yangdong village over the last 8 years. These change are different from the ones occurring in general farm villages. Also, most issues related to the changes are interpreted as occurring as a result of the top-down approach, which disregards the opinions and wishes of residents. For this, introduction of renovation concept that emphasizes modernization of life and production space is urgently required. To this end, it is necessary that concern for the traditional historic village should diversity and expand, and not concentrate solely on the cultural properties and architecture-oriented historic elements.

This study aims for improving the system in Disaster Management of Local Government. In addition, the overall disaster management system was compared to the effectiveness of the disaster prevention system and reliability, and problems and improvement points were derived. The disaster management system in Korea has a structure that promptly investigates and restores damage by a simple procedure. Korea disaster management system manages information on top-down structural disasters through the flow of prevention, preparation, response, and recovery. The process from disaster response to recovery under the leadership of the central disaster safety headquarters is simplified. Disaster management tasks are dispersed among departments, making it difficult to respond promptly. Under the control of the central government, disaster management, such as disaster prevention, investigation, and recovery, are carried out. The disaster management improvement direction of the local government should establish the disaster response system focusing on the local government. Therefore, it is necessary to have budget to operate the organization - centered disaster management budget and the disaster management organization. The disaster response manual should be prepared considering the disaster environment and disaster prevention plan. In order to utilize disaster information, it is necessary to reorganize information system such as integrate and streamline of the private resource database and NDMS.

Timber boardwalk decks are widely installed in parks and scenic areas to provide pedestrians an elevated footpath as well as harmony with the surrounding natural scene. In order to extend the lifespan of boardwalks in the outdoor environment, industrially treated pine timber, such as Pinus sylvestris, is often adopted. However, accidents of pedestrians injured by damaged boardwalk decks have been constantly reported. Therefore, the mechanical behavior of two different types of treated timber was examined in this study under repeated wetting and drying. An increasing number of radial cracks appeared with increasing length and width as more cycles were performed. A loss of more than 40% of the screw withdrawal capacity was observed in both end grain and face grain for the two types of timber after twelve accelerated wet-dry cycles, which coincides with the observation of damaged timber boardwalks in the field investigation. At the same time, it was found that both the compressive and the flexural strength was not sensitive to the wet-dry cycles especially at large cycle numbers.
