  • Objectives: This study evaluated the odor around an industrial complex area (#1-#5) and the operational effects of the Odor Monitoring System in Seo-gu in Daegu City. Methods: Samples were collected from November 2012 to December 2018 and were analyzed for complex odor. The odor occurrence rate and the odor reduction rate were calculated. Results: In 2018, the mean concentration of complex odor decreased 20.9% and the odor occurrence rate decreased from 65.0 to 27.5% around the industrial complex area (#1-#5) in Seo-gu compared to 2013. After the operation of the Odor Monitoring System, the standard excess rate (3.0%→40.8%) and the excess concentration of complex odor (1,442→4,304) increased at odor-emitting workplaces. In addition, the mean concentration of complex odor (15.9%) and the odor occurrence rate (60.6%→32.9%) around the industrial complex area (#1-#5) and the number of odor complaints (23.4%) in Seo-gu decreased. Conclusion: In order to reduce the odor around the industrial complex area, it is important to improve the odor emitting facilities. The Odor Monitoring System uses scientific and systematic monitoring methods that can help control and manage the odor emission facilities.

  • Objectives: This study evaluated the effect of construction on ambient PM-10 in the surrounding area. Methods: Four study sites were selected from total AAQMN 11 points in Daegu city. All the four study sites were located near under or completed construction. Mean monthly PM-10 in 2007 to 2013 were analyzed. Results: Impact of residential construction on PM-10 was more obvious than industrial area. PM-10 was positively associated with number of construction near the study site. When there were 2 or 3 construction sites, PM-10 level was higher. Wind direction and the surrounding terrain affected PM-10. Conclusions: Construction has a strong influence on PM-10 in the surrounding Area. Reduce PM-10 there is the need for special construction site management. Proper management is required to minimize fugitive dust in construction sites.

  • As passing through the Japanese colonial period, Daegu has been changed into a modern city. In addition, the nature of the city had changed a lot by withdrawal of Eup-sung and the opening of the road and the increase of population in Japan. Of course, the expansion of the city was caused by the increase of the Japanese population. To understand the current city, it is most important to understand the past city's characteristics and especially the formation and change of city must be considered with understanding the situation of city. And now the city reflects the role of the city in the past. In fact, the effect of the street constitution in Daegu Eup-sung during Japanese colonial period on the present time was very big and continues. Especially, in order to understand the situation of the city and consider the direction in the future, the analysis of the development process has important implications.This study aimed to consider the change of Daegu Eup-sung Street and Formation of Dwelling Site focusing on the Buksung Street. The purpose of this study is to investigate the nature of the city and changing process of the city by the past Buksung street and the current Buksung street as time goes by.

  • Air Monitoring Network(11 urban stations) is operated to measure ambient air quality in Daegu city. The urban air monitoring stations include 6 in residence area, 3 in industrial area, 1 in commercial area, and 1 in green area. In this study, hourly data (2006. 1. 1~2008. 12. 31) of $PM_{10}$ were measured at 11 urban air monitoring stations. $PM_{10}$ mean concentrations were high in fall and winter because of low wind speed and many haze days. The number of exceeding the daily standard of $PM_{10}$ in industrial area was approximately twice as many as that in residence area. $PM_{10}$ concentrations and visibility were influenced significantly by wind speed. Wind speed and visibility were below 1.8 m/s and 10 km, respectively when $PM_{10}$ concentrations were over $120{\mu}g/m^3$. $PM_{10}$ concentrations were high when haze was observed. The mean concentrations of $PM_{10}$ were $104{\pm}41.3{\mu}g/m^3$, $63{\pm}35.1{\mu}g/m^3$, and $49{\pm}26.9{\mu}g/m^3$, respectively when haze, mist and clear were observed.

  • The population of Daegu, the third biggest city in Korea, is two point six million. Daegu is known as a basin or a city where it is not only too hot in summer but also too cold in winter. Recently with redevelopment apartment house boom, a 40-story or more apartment complexes are under construction near Shin-cheon and Dondaegu-ro, the south-north axis of Daegu. It is necessary to raise several points about blocking a road of the wind by high-rise apartment buildings and apartment complexes. As a kind of the green policy, Daegu enlarge the distance between apartment building by reconstructing low-rise apartment into high-rise and impose a duty of a green space on the ground by making a parking zone into an underground. Through this process, apartment complexes changed from a '一'shape to a '口'shape. It increases heat island phenomenon of a city by blocking a road of the wind that comes from Shin-cheon and Dondaegu-ro. To circulate the polluted air of Daegu basin, we need local wind. There are four effective measures. 1) Throw three greens into one in the center of the road at the north side in the same way of the south side of Dongdaegu-ro, 2) reflect the information of roads of the wind including heights, spaces and directions of buildings, 3) steer clear of a high-rise buildings and development apartment house constructions, and 4)select a city for benchmarking to be the environmental capital.

  • The purpose of this study is to investigate city residents' attitudes and cognition of Daegu City toward Green Tourism. A Questionnaire survey was conducted in september, 2006. The sum of 515 copies was analyzed. City residents recognized the problems of leisure activities as 'burden of expense', 'lack of program diversity' and the advantages of this as 'withdrawal of stress and increase of vitality', 'promotion of health for themselves and their family'. Among theme experiential activities, they preferred 'health/leports experience' 'traditional food experience', 'traditional culture experience', 'nature-ecological experience', respectively. By the result of cross-table analysis, there are many differences between groups by gender & age. Therefore, further development of specific experiencing activity programs and marketing techniques, are required.

  • This study was carried out to characterize the ambient VOCs concentrations of industrial complex in Daegu city. VOCs concentrations of industrial complex area appeared to be higher than those in the non-industrial complex area as following order toluene > ethylbenzene > m,p-xylenes > o-xylene but benzene and chloroform were similar to each other sites. There was seasonal variation of VOCs concentrations in the industrial complex area, higher in summer and lower in winter. In particular the industrial complex area shows that higher on weekday than weekend and higher in the daytime than in the morning or nighttime because industrial complex area influenced by the chemicals. Correlation coefficients among VOCs were confirmed that VOCs of industrial complex area were more related to each other than those of non-industrial complex area and VOCs concentrations have shown generally negative correlation with wind speed.

  • The aim of this study is to analyze the transition of the building of Daegu City Library during the Japanese Colonial Period. To do this, the articles of newspaper and periodicals, books, official documents, official gazettes, statistics, publications of official history of Daegu City Library and research papers were widely collected and cross-checked with each others. As the result of this study, the precedent researches and official history publications related to Daegu City Library had some important errors including the date of the municipal ordinance for Daegu City Library, the first building of Daegu City Library and the date of the breaking-ground, completion and opening for the new building. It is assumed that these errors were generated from the shortage of bibliographic information and full-text databases at those time. At the end of this study, additional research about the history of Daegu City libraries during the Japanese Colonial Period were suggested.
