To study characteristics of the heavy metal pollution, sediment samples were collected at 67 sites on the roadside of Jeonju city during summer and winter, 2002. The total concentration of metals including Cd, Co, Cr, Cu, Ni, Pb, Zn, and Mn in the sediment samples were determined. The results indicate that the roadside sediments in Jeonju city have lower (1/2 to 1/7 times) concentrations of Zn, Cu, Pb and Cd than the metal concentrations previously reported for roadside soil, dust and sewage sludges in Seoul. However, the metal concentrations are higher than environmental quality criteria in soil suggested from several countries, and Zn, Cu, Pb and Cd contents are usually 2-7 times higher than the world average contents of the metals in natural soil. Although pollution index and concentrations of Cr, Ni, Pb and Zn in the roadside sediments at industrial area were usually higher than those of downtown and residential area, the metal having small vehicle- and steel-related industries had high concentrations of metals. The results of chemical partitioning analysis showed that Pb, Zn and Mn are mainly associated with carbonate/adsorbed and Fe-Mn oxide phases but that Cu is largely associated with the organic and sulfide fractions. It thus indicates that both large and small (vehicle- and steel-related) industries are main sources of heavy metal contamination. Due to high solubility of the carbonate phases by natural leaching episodes, the carbonate/adsorbed Cd, Co, Ni, Pb, Zn and Mn in the roadside sediments may serve as a potential source of contamination.

This study aims to analyze the characteristics of ventilation corridor and propose its utilization strategies in Jeonju city in order to discuss how to utilize urban ventilation corridors as a planning factor for reducing heat wave impact and fine particle pollution. For these purposes, cold air characteristics such as cold air flow and height of cold air in Jeonju area located in the Honam Jeongmaek were analyzed and major ventilation corridors were specified. Based on them, we proposed mountain management strategies for securing and utilizing ventilation corridors. We used KALM (Kaltluftabflussmodell), a cold air simulation model developed in Germany and identified both the cold air flow and the height of cold air layer generated during 6 hours at night. As a result, the cold air flow generated in the forests located in the northeast and east sides of the Jeonju city became clear and the height of cold air layer increased in the valley terrain and farmland areas with time. In particular, Jeonju City has an ideal structure of urban ventilation corridor. Based on the results, the area where the cold air generation is active was designated as the 'cold air conservation area', and the area requiring the management for the good cold air flow was as the 'cold air management area'. This study is expected to be used as basic data of policy making and research for reducing heat wave impact and fine particle pollution such as climate change adaptation policy and urban forest plans for ventilation corridor composition.

The purpose of this study is to investigate the actual usefulness and consciousness of bathrooms and to clarify the preference of bathroom plans by apartments dwellers in Jeonju City. Data was collected through self-administered questionnaires and 343 apartments dwellers were used for this study. The major results are as follows. The bathroom types were mostly unit bathrooms and were not suited with using bathrooms of apartments dwellers. The unit type of bathroom was not comfortable for them and most of them were not satisfied with their bathrooms. They usually used family bathroom instead of private bathroom. They wanted a separate space for different facilities such as a bathtub and toilet, a dressing room, and a fixed clothes chest. Generally apartments dwellers did not prefer unit bathrooms, prefering instead the bathroom plan with separate rooms for the bathroom and toilet, with space for dressing. This study suggests that further studies be conducted on apartments dwellers in other big, small and medium-sized cities. Also, it is necessary to offer bathroom plans which take the size of houses and bathrooms, and the number of bathrooms into account and to survey housing consumers' satisfaction of those bathroom plans.

This study was to analyze physical condition on the dormitory high school in Jeonju City, and find out users' satisfaction on that. This was going to contribute to the directions of it's physical environmental improvement. This was performed by a questionnaire survey method. Data were collected from 200 students, who had been dwelling 4 high school dormitories in Jeonju City. Through analyzing those data about library, diningroom, laundry room, break room, computer room, restroom, shower room, hall lounge, and snack bar in a dormitory, the results are as follows. First, students thought some physical conditions to be inconvenient in an distracted study atmosphere and hard furniture of library, a bad location of diningroom, a short laundry machine, lack of tables in a break room, a short performance and supply computer, a small space and short toilet in restroom, and a short of hall lounge and snack bar. Second, the students' satisfaction of common public areas in dormitory was 3.39 score. Students were concerned with library and restroom shower room through analyzing satisfied and unsatisfied areas. Third, they needed to improve heating, cooling, and noise in common areas of dormitory, and needed to support a breakroom and snack bar. Conclusively, library, restroom shower room, break room, and snack bar were important common areas, and indoor environmental elements - heating, cooling and noise- were important in high school dormitory.

In the Republic of Korea, Ministry of Construction & Transportation and Korea Water Resources Corporation manage the national groundwater monitoring network at the 169 stations and will organize the supplementary groundwater monitoring network at the 10,000 stations by 2011 year. The method that organizes the monitoring network was developed using the Analytic Hierarchy Process with pairwise comparison. Several estimation factors for the estimating every district were selected to reflect each district conditions. Their weighting value was decided by pairwise comparison and questions to the experts about groundwater The optimal number of groundwater monitoring well was calculated through the developed method. To verify this method, groundwater was monitored in Jeonju city by way showing the example. The study area In Jeonju city needs 7 stations for the supplementary groundwater monitoring network. The results monitored in 7 stations inferred the groundwater level around the study area by Kriging. The mean of residual between inferred groundwater level value from Kriging and actual groundwater level is rather low. Furthermore, the mean and standard deviation of residual between inferred groundwater level change and actual groundwater change is much lower. The Fact that 7 monitoring stations are sufficient for observing the groundwater condition in the study area makes it possible for suggested monitoring number to be proper.

The purpose of this study is to investigate the actual usefulness of bathrooms and to clarify the preference of bathroom plans by college students in Jeonju City. Data was collected through self-administered questionnaires and 315 college students were used for this study. The major results are as follows. The bathroom types were mostly unit bathrooms and were not suited with using bathrooms of college students. The college students usually used unit bathrooms individually for stool and showering. The unit type of bathroom was not comfortable for them and, therefore, most of them were not satisfied with their bathrooms. They wanted a separate space for different facilities such as a bathtub and toilet, a dressing room, and a fixed clothes chest. Generally the college students did not prefer unit bathrooms, but the bathroom plan with separate rooms for the bathroom and toilet, with space for dressing. This study suggests that further studies be conducted on college students in other big, small and medium-sized cities. Also, it is necessary to offer bathroom plans which take the size of houses and bathrooms, and the number of bathrooms into account and to survey housing consumers' satisfaction of those bathroom plans.

It will be necessary to make proper management plans to preserve the air quality in good level for the public. In order to make these plans, source information and detail emission inventories of the city and near industrial areas should be given. However, lack of the source measurements data makes us more difficult to complete the source inventory. VOC source Inventory could be utilized for the feasibility study to estimate the contribution of VOC sources presenting to the receptor such as residential area. It may give policy maker an idea how to control the air quality, and improve their social environment in the area. This study shows data that measured VOCs concentrations from the local industrial areas in Jeonju during from May 2005 to January 2006. The samples were collected from the near sources in 7 major factories in the industrial park as well as 5 general sources in near city Jeonju area to elucidate the abundances of speciated VOCs and their spacial and temporal distributions depending on source bases. Industrial sources are as follows; chemical, food, paper, wood, metal, non-metal (glass), and painting (coating) industries. The 5 general sources are sampled from tunnel, gasoline gas station, dry cleaning shop, printing (copy) shop, and road pavement working place in urban area. To understand the near source effect at receptor, samples from the 2 receptor sites (one is at center of the industrial complex and the other site is at distance residential area downwind from the center) were collected and analyzed for the comparison to source concentration. The mass contributions of the speciated VOC to total mass of VOCs measured from the different sources and ambient (2 receptors) were presented and discussed.

This paper aims to examine economic values of green spaces for non-Capital areas that have been rarely studied. Choice experiments were applied to two dissimilar but adjoining areas: The City of Jeonju and Wanju County. Split-sample surveys allowed to compare between apartment dwellers and single- or multi-family house dwellers, and across differing types of green spaces. According to the results, significant and substantial preferences might prevail not only for large cities, but also for agricultural areas. The mean willingness-to-pay (WTP) values of apartment dwellers for the view of a river/lake or mountain were generally smaller than those of Seoul, while the overall access values showed the opposite relationships. House dwellers in Jeonju showed substantially larger economic values for green spaces than those of the counterparts in Seoul, except for the access value of a river/lake. The findings grant follow-up studies investigating the reasons for the anomalous preferences particularly in Jeonju and identifying new management policies for non-Capital areas.
