This study analyzed the effect of social, economic, and physical improvement in urban regeneration projects using difference in difference method in Busan and Cheongju City, utilizing population, regional economic, and old building data. The results of analysis indicated that the urban regeneration project had no effect on the social, economic, and physical improvement of the project area comparing the neighboring areas. In other words, at the end of the urban regeneration project, the business performance was not evident. Therefore, it is difficult to expect social, economic, and physical improvement if the urban regeneration project does not consider the linkage with the detailed project composition. In particular, it is necessary to carefully select detailed projects that meet the purpose of the project when establishing urban regeneration plans in the future.

The purpose of this study was to examine the state of convenience facilities for the disabled in dental institutions in an effort to provide some information on the improvement of the accessibility of disabled people to dental institutions. A survey was conducted on the licensed dental institutions in the city of Cheongju, North Chungcheong Province, from March to April, 2011. The findings of the study were as follows. The dental offices were the majority of the dental institutions investigated, and for the establishment of the dental institutions. Some of the offices were established before 1990, and some were established in 2011. The time period of establishment varied within the offices. As for the location of the dental institutions within the buildings, they were mostly on the second or third floor. Regarding the convenience facilities for the disabled, the most installed convenience facilities were boardwalks and elevators, and the least installed ones were parking lots and restrooms for the disabled. The hospitals and public dental centers were equipped with all the convenience facilities investigated in this study. Overall, the dental institutions that were established in and after 2006 were equipped with more convenience facilities than the dental institutions that were established before 1990. And the dental clinics that were on the third or higher floor were more equipped with elevators and outdoor slope ways than those that were on the first or second floor. Therefore the revision of the law is required to urge even the primary dental institutions to compulsorily install the convenience facilities. The findings of the study are expected to make a contribution to the improvement of the accessibility of disabled people to dental institutions.

The ultimate goal of urban regeneration is the economic development and activation of region. In order to continue to management the urban regeneration projects and to achieve a goal, we should look at the recognition of people visiting the place. This recognition is represented as a place attachment. Place attachment is the realizing means for local activation by inducing a lot of attention and a visit to place. Accordingly, this study was selected the Jungang-dong in Cheongju as a case study and measured awareness of the physical environment and activity programs. Based on the survey, this study analyzed the impacts of awareness of urban regeneration project on place attachment by carrying out multiple regression analysis. According to the analytical results, Visitors formed an place attachment called 'I want to stay here longer' and 'I will miss here if this place has changed'. However, visitors are unable to form an place attachment called 'Here is a distinctive place'. Finally, this study suggests the direction of urban regeneration projects to reflect the physical environment and activities programs at the same time and form the rich psychology of visitors.

The paper presents the results of qualitative analysis of phthalate esteres in Miho stream in of Cheongju city. Phthalate esters (Di-2-ethylhexylphthalate, Di-n-butylphthalate) are widely used as plasticizers to increase the flexibility and workability of high-molecular-weight polymer. For water phase, DEHP concentration in upper stream and down stream were $12-18{\mu}g/{\ell}$ and $11-21{\mu}g/{\ell}$, respectively. For sediment phase, DEHP concentration in upper stream and down stream were $0.07-0.82{\mu}g/g$ (dry) and $0.06-0.92{\mu}g/g$ (dry), respectively. Also, DnBP concentration of sediment in same site were $0.04-0.25{\mu}g/g$ (dry) and $0.08-0.34{\mu}g/g$ (dry), respectively. DEHP and DnBP concentration of water phase in the small stream of industrial area were $13-28{\mu}g/{\ell}$ and $2-8{\mu}g/{\ell}$, respectively. DEHP and DnBP concentration of sediment phase in the small stream of industrial area were $0.12-0.7{\mu}g/g$ (dry) and $0.17-2.16{\mu}g/g$ (dry), respectively. Phthatlate esteres in water and sediments phase of Miho stream were lower than water bodies around the world.

By securing golden time, this study analyzed the effects of an emergency vehicle priority system in Cheongju, North Chungcheong province. Until the scene of a fire is reached, severe obstacles in the street, such as traffic congestion, cars coming forward, non-cooperative vehicles etc., are significant. To solve these problems of road obstacles, it is essential to adopt an emergency vehicle priority system. From April 2017 to June 2018 (1 year and 2 months, 426 days), the dispatch time and date, fire truck moving distance and required time, traffic signal control section and pass time, and shortening time, were measured. This study selected 140 cases consisting of five heavy traffic and frequent dispatch routes out of 293 cases. The effects of the emergency vehicle priority system were excellent. Overall, it took 3 min 3 s to pass 1 km on an uncontrolled traffic signal section. On the other hand, it took 1 min 23 s to pass 1 km on the same section that was controlled. The shortening time to pass 1 km was 1 min 40 s, showing a 45.4% reduction. This means that the 15 min driving time can be reduced to 6 min and 49 s. From this result, an emergency vehicle priority system should be implemented nationwide as soon as possible.

The concentrations and loads of total nitrogen (TN), total phosphorus (TP), and chemical oxygen demand (COD) in wet deposition were investigated at Chungbuk National University in Cheongju, Chungbuk. Event based precipitation samples were collected during 1998 to 2003. The precipitation-weighted mean concentrations of pollutants were 0.60 mg/L for TN, 0.014 mg/L for TP, and 4.8 mg/L for COD, which were smaller than its arithmetic mean concentrations by 26% for TN, 18% for TP, and 14% for COD. The concentrations of TN, TP, and COD significantly decreased with precipitation. Mean concentrations of pollutants in spring (March-May) were higher than in other seasons likely due to dust caused by wind erosion and sand-dust storms, pollen etc. Significant relationships were determined between TN and TP, and TN and COD. Annual loads of wet deposition averaged 7.9 kg/ha$\cdot$yr for TN, 0.19 kg/ha$\cdot$yr for TP, and 63.9 kg/ha$\cdot$yr for COD, which are almost identical to the values of TN and TP but slightly higher than COD value reported in Japan.

Holocene vegetation and climate changes were assumed on the basis of pollen records from Wonpyeong Trench II-3 of the Osong archaeological site, Cheongju, Chungbuk Province, Korea. An organic matter beared in coarse sediments appeared to be low throughout the succession. Although an occurrence of pollen grains is not high, some dominant and principal taxa may indicate vegetation changes response to climate changes in central inland area of the Korean Peninsula. The age determination can be estimated with indirect way by comparing with previous age-controlled pollen studies. It is assumed that the former last glacial conifer forests had been changed into open mixed conifers and deciduous broadleaved forest during the early Holocene period. Warmer and more humid climate conditions, during the mid-Holocene, might have allowed the hardwoods including deciduous- and evergreen-broadleaved trees, and warm-preferring pine tree to flourish. Subsequently, the former forests were replaced by mixed of conifer and deciduous broadleaved forest owing to deterioration of climate conditions during the late Holocene. Human activity is also detected by agricultural indicators, such as buckwheat and large pollen grains comparable to corn, in upper most pollen profile. During this time, the forests in studied area were primarily affected by human disturbance rather than natural environment.

The study on urban regeneration began in 2006 and has actively proceeded for 10 years. Also, there are a lot of studies related to urban regeneration have analyzed urban regeneration effects but have just focused on qualitative analysis. Therefore, this study has intended to analyze the urban regeneration effects of Junang-Dong, a central business district in Cheong City, where urban regeneration projects have been undertaking, in the manner of quantitative analysis. To reach this objective, we selected such indicators as floating population, public land price, a and vacancy rate, and set analysis time span from 2011 to 2016, when urban regeneration projects have been actively operated. As a result, this study has found the following results. 1) As for floating population, population index grew gradually and showed an drastic increase of about 65 percent in 2014 when the project was active. 2) Public land price of Jungang-Dong has been showed the greatest increase from 2011 to 2012 when the city started to regenerate, and slight decrease from 2015 to 2016 with the gradual decrease until 2015. 3) In terms of vacancy rate, there has been declined about 15 percent from 27 percent to 12 percent, with a steady downward curve. This study has dedicated itself to analyzing the urban regeneration effects quantitatively especially in commercial business district.

The purpose of this study is to develop a traffic characteristic analysis, a correlation analysis with the variables of traffic characteristics, and accident estimation models while recognizing the seriousness of the traffic accidents. The analyses deal with the 181 4-legged signalized intersections that accounted for 1,183 out of 3,115 accidents in Cheongju in 2004. After measuring ADT, intersection area, average lane width, elevation, and other items as independent variables and the number of traffic accidents, the traffic accident rate (accidents per million entering vehicles) and equivalent property damage only (EPDO) figures as dependent variables which are estimated as influencing signalized intersection accidents, the estimation models are developed using correlation analysis and multiple regression analysis. In the analysis of the number of traffic accidents, the model indicates an $R^2$ of 0.612, and five independent variables are taken as significant factors. In the analysis of traffic accident rates, the model indicates an $R^2$ of 0.304 and five significant factors, including intersection area and ADT. Also, for the analysis or the EPDO numbers, which coincides with understanding the seriousness of the traffic accidents and the traffic characteristic analysis, the model indicates an $R^2$ of 0.559, and four independent variables (ADT, main street average lane width, elevation, and speed limit) as significant factors.

This study aimed at examining whether the national rental housing supplied by Korea National Housing Corporation (KNHC) is truly contributing to the upward mobility of housing in low-income households without their own house by comparatively analyzing whether those who moved out of the national rental housing made upward, horizontal or downward housing type mobility. The subjects of this study included 333 people who had moved out of three national rental housing complexes in Cheongju, Chungcheongbuk-do in 2007, which had opened to the first residents two years ago. A telephone survey involving the subjects was carried out. Collected data were analyzed through frequency analysis, cross tabulation analysis and multiple regression analysis, with using the type of residential mobility(downward mobility, horizontal mobility or upward mobility) according to "housing size" and "housing costs" as a dependent variable, and personal and family environment and economic environment as independent variables. According to the results of the analysis, 76.4% of the households made an upward mobility, 1.6% remained little changed, and 22% moved downward in terms of "housing costs," compared to before moving into the national rental housing and while living there. Furthermore, in terms of "housing size" 61.8% of the households moved upward, 16.5% remained little changed and 19.7% moved downward. The variables affecting the upward mobility of housing type included the number of income earners in a household, income earner's occupation and education level. Income earner's amount of income, age and family to support, on the other hand, turned out to have little effect on the upward mobility. Based on the results of the study, the following suggests were made for the supply of effective national rental housing. First, various features of each type of residential mobility should be reflected. Second, national rental housing residents' self-sufficiency should be enhanced to help them move upward in housing type.
