Recently, structure safety management techniques using cutting-edge technology(Displacement senor, sensor of acceleration) has emerged as an important issue owing to the aging of infrastructure such as bridge and building. In general, the structural monitoring system for structure safety management is based on IT technology and it is expensive to install. In this paper developed an image-based structure dynamic characteristic analysis system prototype to assess the damage of structure in a more cost-effective way than traditional structure health monitoring system. The inspector can take a video of buildings or other structures with digital camera or any other devices that is passible to take video, and then using NCC calculation for image processing technique to get natural frequency. This system is analysis of damage of the structure using a compare between the frequency response ratio and functions when problems are occurs send alarm to administrator. This system is easier to install and remove than previous monitoring sensor in economical way.

Completed in September 1796, Suwon Hwaseong Fortress is a defense facility with 49 facilities spanning 5,744m. During the Japanese occupation and the Korean War, many buildings and walls were damaged, and in 1975, it was restored to its current state through the restoration and restoration project in Suwon. Six of the entire facilities have not been restored by urbanization, of which the restoration of water spaces, including ditches buried in the ground, could be used as a place of rest and viewing for visitors. Tourists visiting Suwon Hwaseong, are satisfied with exploring the historic sites, but feel insufficient for enjoying the natural scenery around the castle. The best way to create a natural landscape in Suwon Hwaseong, where urbanization has been developed, is to create a water space to make you feel the traditional garden. Therefore, the location, shape, and functions of the unrestored water space of Hwaseong Fortress were analyzed through the analysis of 『Hwaseong Seongyeog Uigwe』 and 『Hwaseong Full Map』. The purpose of this study is to derive the traditional landscaping method by analyzing the characteristics of water space.

Just as social welfare facilities and system are the barometers of a nation's quality & standard of living, the facilities of student's union building symbolizes level of welfare facilities and systems of a university. A university is a group of individuals searching for and studying the truth, so it is the highest of all education centers. At the same time, a university builds one's character. this infers that leisure activity in a university is a condition that facilitates the ability to create a healthy body and healthy soul. Additionally, active experiences for a human social life take people away from daily stresses and release the tensions of university studies. Therefore, a university campus should be built not only for students researching and studying, but also to aid in the growth of a students body, soul and mind. When creating a university master plan, increasing the number of students, promotion of a good educational environment and preparation of students for future development should be of primary consideration. There are several factors to aid this. The factors are; the academic plan, leisure activity, the belief system of university student and physical and environmental factors. The research presented here tells us the most important factor for developing the master plan of a student's union building

The function of officetel has been changed from office use to residential use since 1980s. The construction of officetel was relatively increased in 1991, has been decreased in the middle of the 1991, and has been increased after 1996. This paper is an empirical examination of officetel rent determinants in Seoul. Hedonic regression analysis provides the basic framework for this study. The major rent determinants are the preferable location of buildings, the ratio of private use area to the building area. residential use. The officetel rents are likely to increase at an increasingly rate with respect to these variables. The significant and positive determinants that impact rents is the building story height for the officetel for business use, and the ratio of private use area to the building area for the officetel for residential use.

At present, the research of the method of 'Blank-Leaving' can be easily found in works of arts and architecture, while it can be hardly discovered in the academic research of film and television. However, as a means of expression, 'Blank-Leaving' gives a unique artistic charm to film and television works, and its development has a positive aesthetic effect to film arts. In order to go into details of the thought of 'Blank-Leaving' in movies, this paper firstly discusses the definition of 'Blank-Leaving', the history and social origin of 'Blank-Leaving' as well as its relationship with Taoism and its application in traditional Chinese painting. Secondly, this article analyzes its function and artistic expression in the film and television and the ideas sublimation it brings to people by means of combining the thought of 'Blank-Leaving' in Taoism. Finally, this work put forward the method of innovation and perfection of 'Blank-Leaving' in film and television works. This paper shows that, as a means of expression, 'Blank-Leaving' has not only realized the value of beauty, but also strengthened the public awareness of film arts.

This study applied a hydraulic rock splitting system equipped with a hybrid packer to the bench-cut method. The hybrid packer system is an improvement of the packer developed in previous studies; it is designed efficiently to reduce vibration and noise during rock excavation by combining the two functions of inducing hydraulic fractures using injection pressure and then expanding and extending them using a rubber packer. Field experiments assessed the efficiency of rock excavation with respect to the injection conditions; the adjusted experimental conditions included the distance from the free surface and the test holes drilled at the top of the slope and the injection settings. Using a separation of 5 m left some unexcavated parts, but using a separation of 1 m left no unexcavated parts. The hydraulic fractures generated by the injection pressure developed generally parallel to the free surface and expanded and extended as the rubber packer expanded, thus facilitating bench-cut excavation. For hydraulic rock splitting to be broadly applicable to bench-cut rock excavation, it is important to accumulate results from many field experiments conducted under varying experimental conditions for various types of rockmass.

In recent years, there has been a tendency to reuse 'landscapes of memory,' including industrial heritages, modern cultural heritages, and post-industrial parks, as public spaces in many cities. Among the various types of landscapes, 'modern historic landscapes', which were formed in the 19th and 20th centuries, are landscapes where the debate between conservation and removal is most frequent, according to the change of evaluation and recognition of modern history. This study examines conflicts between conservation and removal around modern historic landscapes and explores the value judgment criteria and the process of formation of those landscapes, as highlighted in the case of the demolition controversy of the old Japanese general government building in Seoul, which was dismantled in 1995. First, this study reviews newspaper articles, television news and debate programs from 1980-1999 and some articles related to the controversy of the Japanese general government building. Then it draws the following six factors as the main issues of the demolition controversy of the building: symbolic location, discoveries and responses of new historical facts, reaction and intervention of a related country, financial conditions, function and usage of the landscape, changes of urban, historical and architectural policies. Based on these issues, this study examines the conflicts between symbolic values that play an important role in the formation of modern historic landscapes and determines conservation or removal, and the utility of functional values that solve the problems and respond to criticisms that arise in the process of forming the modern historic landscape. Especially, it is noted that the most important factor that makes the decision is the symbolic values, although the determination of the conservation or removal of modern historic landscapes has changed according to changes in historical perceptions of modern history. Today, the modern historic landscape is an important site for urban design, and still has historical issues to be agreed upon and addressed. Thi study has contemporary significance from the point that it divides the many values of modern historic landscapes into symbolic values and functional values, evaluates these, and reviews the background social context.

To improve the social and economic position of the disabled people and secure their human rights, an integrated society should be buill. To build such a society, an adequate access should be provided to the movement or in using buildings or facilities. The inconveniences from social life on the part of the disabled people might not result from their impairment or disability, but from physical and social barriers in the environment surrounding them. Therefore, it is necessary to reconstruct entire systems of the society as a disabled people-friendly structure in order to remove those barriers, make them stand their own feet in our communities and freely participate in the social activities. This will eventually lead to build a society in which all people including the disabled people can use those facilities in a more convenient way. It is almost impossible for the disabled people to safely and conveniently access to and use facilities and equipments and freely move to their desired places, without any help from others in Korea. Even though, there are currently many disabled people-related convenience facilities, they have been independently built without a connection with other facilities and buildings, thus not greatly useful. Even when convenience facilities have been built, mostly they are superficially set up; therefore, in many cases, the disabled peOple cannot use those facilities. In this. research, I tried a new concept of mobile wheelchair lift design, which the disabled people can operate without restrictions, when using the public facilities. The key to this research was to develop the existing import-oriented simple functional products to a new system with functional safety and high quality orientation. Also, this research aimed at bringing an. import substitution effect, as well as preempting the mobile wheelchair lift market by advancing into overseas markets through application of new image designs in the field of disabled people aid equipments.

Paju Mok was the local administrative office of the Joseon Dynasty as the administrative and transportation center of western part of Gyeonggi-do and used as a Haenggung when the king visited the royal tomb of the Joseon Dynasty. Paju Mok Government Office was adjacent to Uiju-ro, which connects Hanyang and Uiju in the Joseon Dynasty. Paju Mok Government Office is an important place in the northern part of Gyeonggi, where the king stayed when he visited the Jereung, Hulleung which are located in the northern part of Hwanghae Province and Paju Yeongreung and Jangneung, Paju Mok Government Office was maintained until the 1900s. After the Japanese colonial Period, Government Office buildings are used for other purposes, and their function as a Government office is impaired. In addition, most of the buildings disappeared due to the Korean War, and now the state of Paju Mok Government Office was lost. In order to restore the lost Paju Mok Government Office, it is necessary to study the composition of Government Office, such as the place where Paju Mok Government Office is located and major buildings. Therefore, if you find out the location Estimation, spatial composition and size of Paju Mok Government Office by analyzing and analyzing ancient documents and ancient books related to Paju Mok Government Office, and the topographic map and cadastral map and land survey department during the Japanese colonial period, you can be used as basic data when restoring Paju Mok Government Office.
