Objectives: The purposes of this study were to investigate the installation rates and status of indoor smoking rooms in public facilities and to determine the level of compliance level with smoke-free policies in accordance with the National Health Promotion Act. Methods: A visiting survey was conducted on 1,206 public facilities in the Seoul Metropolitan Area and the Daegu and Gyeongsangbuk-do Province area. Researchers selected public facilities such as bars, coffee houses, and internet cafes using convenient sampling. They visited without prior notice, checked the existence of indoor smoking rooms, and recorded their status. Results: Internet cafes (110/116) had the highest installation rate of indoor smoking rooms, followed by bowling clubs (17/19) and billiard rooms (87/100). Depending on the type of business, 50-88% of smoking rooms were not completely enclosed. Coin karaoke rooms showed the least inadequacy in this regard. In addition, out of 512 smoking rooms, in 33% (n = 169) smoking indoors was observed in non-smoking areas. Only 9% of public facilities were in full compliance with the indoor smoke-free regulation. Conclusions: It was found that most of the public facilities with indoor smoking rooms did not comply with the smoke-free policy, and smoking was still observed inside some facilities. Therefore, there is a need for a policy that prohibits indoor smoking rooms completely.

The purpose of this research is to provide a basic knowledge to open up for undeveloped park in process of the park policy establishment by setting up the priority of park development and valuation factor, valuation index as well as building a basic material to undeveloped neighborhood park in Daegu Metropolitan City. Thirteen urban neighborhood parks(1,841,663$m^2$) in the Daegu Metropolitan City were selected for this study. Analyzing and reviewing the previous research and literature review were conducted, and the evaluation index and analysis criteria were constructed to decide the development priority of parks. The results of this research are as follows; 1) Following to the result of the expert questionnaire test in order to estimate weight of valuation factors. It had a high score in available population, and estimated amount of the gross compensation, unpurchased land rate. On the other hand park rate of autonomous district, altitude, rate of population increase in autonomous district and a low score. 2) Generally, most f the plain type parks had a high score in the Sea level, land using pattern, an estimated amount of the gross compensation, but hill type parks had a high score the rate of green covered, park area for one person of administration building. 3) Daebong, Soosung, Dosan, 2.28 youth, Kyungnam parks were selected high priority. Soochang, Donsibong, Janggi, Dongin parks were selected middle priority. Bokhyun, Galsan, Manchon, Gusoosan parks, which were selected low priority. This research for undeveloped park is a basic research step to open up. Three many difficult things in shortage of the basic material for building valuation factor and measuring of the method measurement. The application of weight which make a decision importance among the valuation factor should have ore reasonable study and more scientific research from now because there still remains a lot of shortage of positive materials in there.

The main purpose of this study is to identify urban spatial structure by applying geographic information system and remote sensing data. This study identifies the urban spatial structure of non-megalopolis by analyzing the spatial distribution of population and employment in the case of Daegu metropolitan area. For this purpose, multi-temporal satellite image data (Landsat TM; 1995, 2000 and 2005) were utilized through the geographic information system. The distance-decay estimations in terms of population and employment density show that Daegu region as a whole shows monocentric urban characteristics. However, some evidences of polycentricism such as low explanation power of monocentric urban model, rises in multiple employment centers, decentralization of employment are emerging.

The purpose of this study is to assess naturalness of each and use type for Daegu and provide the basic data for urban green space planning. The results are as follows: 1) As a result of periodic analysis, It is known that in the 1400´s that the rate of a-/oligo-/meso-hemeroby was over 90% of that area, in which naturalness was very high. By the 2020´s, the population will increase to about 3,500,000 and the occupation rae of meat-and poly-hemeroby, where naturalness is very low, is expected to increase rapidly. 2) The recent land uses of Daegu are divided ito 17 types. In the survey of a occupation rate of each land use type, a forest are occupies 48.8% of the entire area. The military installation zone is lowest with 0.07%. 3) Investigation of a dominant hemeroby grade in each land use type showed that the urban complex area in characterized by meta-hemeroby : and the space for pavement and building construction where naturalness is lowest. On the other hand, oligo-hemeroby that is worth being preserved was surveyed to be dominant in woodlands and natural forests. 4) In the analysis of hemeroby mapping in the process of a green space planning, it is clear that hemeroby will be used a s a tool that assesses the suitability for recreation activity of each sample case. For example, it enables a poly-hemeroby region to be utilized as a near-natural recreation area including $\beta$-and $\alpha$-euhemeroby region in Daegu. Besides, hemeroby can provide basic data to make a value judgement of each sample case with a view to preservation of nature.

This study investigates the temporal structure and movement of floating people near university areas in Daegu metropolitan city, South Korea, before and after Covid-19. In order to determine Daegu's position, the current study compares Daegu and Seoul. The floating population is used as an index to reveal people's various activities in the area known as the local business district, which surrounds the university campus. The information was provided by mobile phone manufacturers. A municipal authority managed a public website where mobile data was made available. Several statistical and visualization techniques were used after the data pre-processing steps. As a result, the floating population fluctuation patterns in both cities in the first half of 2019 and 2020 were comparable. When the Covid-19 diffusion rate in Daegu stabilized in the second half of 2020, the floating population in Daegu increased slightly over the previous year, while the population in Seoul decreased due to the second wave of Covid-19.

This study aims to examine the actual status of the urban heat island in Daegu by analyzing the data of 17 automatic weather stations installed in the Daegu area. And the results can be summarized as follows: First, regarding the temperature distribution in Daegu by summer time zones, for the 31 days(August 1st till 31st), 18 days showed daily maximum temperature over $30^{\circ}C$, and 11 days indicated daily minimum temperature over $25^{\circ}C$. The day that showed the highest daily maximum temperature was August 5th, which indicated $36^{\circ}C$. Second, about the spatial distribution of time ratio exceeding $30^{\circ}C$ and $25^{\circ}C$, the area with the highest time ratio exceeding $30^{\circ}C$ is mostly the downtown(central area), eastern area, and northern area. Meanwhile, regarding the time ratio exceeding $25^{\circ}C$, the downtown area centering around the central area were high as over 70%, and the outskirts were low as under 65%. Third, considering the temporal distribution of daily maximum temperature and daily minimum temperature, daily maximum temperature was shown around 14:00 to 15:00 while the daily minimum temperature was indicated around 17:00 to 18:00. Daily maximum and minimum temperature were appeared at northeast and downtown, respectively. Fourth, regarding the spatial distribution of tropical days and tropical night days, tropical days showed 77% and tropical night days indicated 42% before and after the 24th and also the 13th each. Tropical days were occurred up to 24 days at northeastern area. And the southwestern area of Daegu showed under 22 days. The downtown showed the 14 days of the tropical night. However, the outskirts indicated relatively few days as under 10 days. Fifth, about the spatial distribution of the average daily temperature range (the difference between the highest temperature and lowest temperature), the central area, the central part of the city, showed the smallest as $7.2^{\circ}C$, and as it was closer to the northern area, it became larger, so in the eastern and northern area, it was over $8.8^{\circ}C$ or so.

One of the most important elements in creating the pleasant residential environment is the wind. For the pleasant residential environment, it is important that the air pollutants are not stagnant but appropriately and swiftly diffused and removed by winds. Especially, the river becomes a main route of wind in the urban core. So, it is necessary to secure the space to circulate the sufficient cool air to this area. But, recently many high-rise apartment complexes have been built along the rivers that have the fine view and pleasant environment. As a result, the cool and fresh air coming from mountains hardly diffuses into the urban core but just flows along the river. Considering the facts above, this study selected types of building layout and kind of land cover as complex or architectural design factors that have an influence on wind environment. Based on the factors, it analyzed change in wind environment according to apartment complex development aiming at the Sinchun area which is Daegu Metropolitan City's main wind corridor. Therefore, when apartment complex development is planned in the future, it can offer basic data for establishing plans for more pleasant complexes. As a result of the analysis, it was shown that the layout type of housing and the building height plan in consideration of wind corridor around the river were pretty effective in increasing the wind speed and circulating the air in the apartment complex. Therefore, if wind corridor is considered when apartment complex development is planed in the future, this study can offer useful information contributing to improve comfort in residential environment in the level of complex building as well as city planning.

The primary purpose of this study is to identify the characteristics of land use change at the urban fringe. For this purpose, the Daegu Metropolitan City is selected as a study area. Land use changes between 1990 and 2000 in fringe areas are identified by processing Landsat TM5 imageries. The main findings are follows: First, land development has been driven by residential development, especially large-scale residential development encouraged by the two-million housing construction plan. Second, the type and size of the land use conversion are not identical across the study area. For example, the main land use type of the newly developed area of Buk-gu is residential use while that of Suseong-gu is public use. Third, most of residential development type is a high-density development which is quite different from American type of low-density development.

This study examines the emerging global city-regions theory and suggests its implications for regional development policy in Korea. Global city-regions defined as an economic and political organization of metropolitan regions or a new scale of urban organization with polycentric structure, is appreciated as a new regionalist model of development in the globalization era. In Korea, the application of global city-regions model is required particularly for strengthening the international competitiveness of metropolitan areas except the capital region including Seoul, and resolving inequalities between the capital region and non-capital regions. However, Institutional revolution including consolidation of Shi(metropolitan area) and Do(province), and devolution should be preceded above all things to develop metropolitan cities such as Busan, Daegu, Gwangju, and Daejeon toward global city-regions.
