This paper looks into how to preserve Gyeongju's natural environment and to restore its historic landscaping works, one of the greate factor that compose ancient city as a way of wisely preserving Gyeongju, one of the oldest cities of Korea. Gyeongju, a city based in its natural environment, is formated inside of a basin of mountains and streams. Mountains and streams are the major two factors when on thinks of preserving the ancient city of Gyeongju. Four mountains surrounding the city play a direct role in marking coordinates of major city landmarks, while streams influence the structure and formation of the city in a great deal. More precisely, mountains should be able to be seen from the center of the city and streams should be restored in a way that they can serve as scenic identities of their time. Efforts should also be put into restoring such elements as ancient gardens, royal forests and water ways. The research team believes that such efforts themselves will be a great methods in reclaiming historic values and significance of places of Gyeongju. Restoring an ancient city is not limited merely restoring a city in an artificial concept, it reaches to preserving natural environment as a backdrop of the city and traces of landscaping works. When it comes to restoring an ancient city, one must understand that preserving natural environment and historic landscaping works are as valuable as restoring city structure or constructional elements. We believe that defining subjects of ancient city restoration must be more precise, clear and detail down the road.

Since the 1990s, with the beginning of local autonomy, most Korean cities have tried to establish and reinforce their own identity. The Law on the Planning and the Use of National Land, which took effect in January 2003, requires major and minor cities to manage and develop a city image and a marketing strategy to reflect their current condition. However, many cities continue to experience confusion in implementing urban landscape planning because no efficient and systematic method has been provided for the analysis of a city's image. The absence of systematic analysis methods makes it difficult not only to assess the current condition of a city accurately but also to choose an appropriate policy for the given city. Consequently, many cities suffer excessive trials and errors in implementing the correct policies for their city. The purpose of this study was to analyze the image: of Kongju, which has many historical properties. For this purpose, adjective questionnaires and multi-dimensional scaling (MDS) were made use of in order to assess the city image. The results of this study can be summarized as follows: 1. There are five properties that serve as landmarts lie symbolize Kongju: Muryeong royal tomb, Castle Kong, Mt. Gyeoiryong, Forest Museum, and Kongju National Museum. 2. Based on the citizen survey regarding the city type, Kongju is seen as a historical and an educational city. 3. Based on the image positioning (image spatial plot), Kongju is described as an old and familiar city. There we, however, no landmarks which are in accord with the image of Kongju. It is difficult to establish and reinforce the image of a city with a single element like a landmark However, with steady follow-up research, this study may serve as a systematic and logical model to improve the urban landscape and image.

The purpose of this study is to develop the evaluation system of which the city safety can be realized in the U-City. The evaluation system on "how much safe the present city is" and "how much safe it will be in the future" has been selected and the criticality has also been analyzed. The result of criticality analysis is that the indicator for "how safe the current city is" showed that the disaster prevention and environmental field are important. In the future, the indicator of possibility for the U-safe city should be prepared by the imtegrative operation management system, and on the basis of this, it also showed that the necessary indicator to build the system for keeping the safe city is important. The evaluation system for the U-safe city, hereafter, can be utilized for the city plan, construction, operation, and management utilized by IT in local government.

This paper is a study on city brand development which is increasingly interested as a means to enhance the attractiveness of the city. the previous research, the design of city brand identity was an application from the internal stakeholder's point of view related to the metropolitan government. However, in the present study, we tried to take a external approach that perceptions and designs city brands from the related to the consumer. For the purpose of research, based on previous studies, we extracted three images of leading, stable and amusing city brand images and prepared three scenarios for the imaginary city as experimental stimuli. The results showed that the overall city brand attitude, residence intention, and tourism intention to the imaginary city were significantly different according to the leading, stability and amusement brand image. According to the results of this study, it is necessary to continuously effort the development of city brand image which is perceived by consumers in order to differentiate city.

Objectives: This study evaluated the odor emission characteristics from fundamental environmental facilities at an industrial complex area in Daegu City. Methods: The odor samples were collected from May 2015 to January 2016 and were analyzed for specified offensive odor substances. The odor quotient and the odor contribution was calculated. Results: Ammonia was detected in all samples monitoring specified odor compounds, followed by hydrogen sulfide and acetaldehyde. According to contribution analysis, hydrogen sulfide shows the highest contribution in all facilities. At wastewater treatment plants A and B and sewage treatment plant F, it was followed by acetaldehyde. At wastewater treatment plant C, it was followed by imethyl sulfide. Conclusion: The major component of odor can be determined by evaluating the degree of contribution to the odor intensity rather than the concentration of the individual odor components. To increase the effectiveness of odor reduction, policies focused on materials with a high odor contribution are needed rather than focusing on high-concentration odor compounds.

Objectives: This study evaluated the regional and seasonal concentrations of ambient hazardous heavy metals in an industrial complex area in Daegu City. Methods: A total of 64 SPM (Suspended Particulate Matter) samples were collected in non-industrial and industrial areas during 2014 and were analyzed for hazardous heavy metals elements (As, Cd, Mn, Ni, Pb) with ICP after acid extraction. Results: SPM and hazardous heavy metals concentrations showed regional (industrial complex area>non-industrial complex area) and seasonal (spring, winter>fall, summer) variations. All of the hazardous heavy metals were influenced by anthropogenic sources. The pollution index of hazardous heavy metals was very low, showing roughly one-quarter of the level of the air quality guidelines of WHO. The correlation analysis among SPM and hazardous heavy metals indicated that components of non-industrial complex areas were more related to each other than those of industrial complex areas, and the correlation in the winter was higher than in other seasons. Conclusion: It is necessary to control air pollution sources and establish related policy because hazardous heavy metals from industrial areas can influence residential areas.

Korean government is promoting "K-Smart City" to overseas market which is an integrated solution of construction industry with ICT(Information and Communciations Technologies) industry. Due to nature of Smart City, construction quality and the development quality of the facilities need to be established to improve the overall quality. However, guidelines and regulations to initiate quality control for Smart City are behind the actual demand. This deficiency is bringing quality control for construction and ICT to be controlled separately causing lack of synergy and resulting in overall quality degradation. This research is designed to improve the construction quality of Smart City during its establishment stage by integrating ICT system with on-site construction (Integrated control center and on-site equipment). The adoption of this research to a real Smart City case had resulted in 22% reduction of construction inspection failure (Audit), and also allowed Construction Company to pre-align quality control of all purchased items of ICT Infra that resulted in 18% reduction of nonconformity, thus contributing to an overall quality improvement. This research is expected to be used widely among all construction industry of Smart City.

The goal of this study is to deduce the image of city people on rural district, and to clarify the city people's demands on rural tour and their consciousness on green tourism. This study also aims to propose the effective ways of improving the environment of rural district to revitalize green tourism and to promote the exchange between urban and rural districts. The study results indicate that most city people have a warm-hearted lyric image on rural district. In addition, it is indicated that the city people like the rural district with beautiful scenery, which is easy to contact with nature. On the other hand, as the goal of green tourism, in addition to the contact with nature, the exchange between urban and rural districts and the understanding on the rural life through personal experience are also considered very important. Finally, the city people are classified into four types, and it is necessary to develop the green tour program with emphasis on the city people of overall-type.
