  • This study is focused on manganese (Mn(II)) removal by potassium permanganate ($KMnO_4$) in surface water. The effects of bicarbonate on Mn(II) indicated that bicarbonate could remove Mn(II), but it was not effectively. When 0.5 mg/L of Mn(II) was dissolved in tap water, the addition of $KMnO_4$ as much as $KMnO_4$ to Mn(II) ratio is 0.67 satisfied the drinking water regulation for Mn (i.e. 0.05 mg/L), and the main mechanism was oxidation. On the other hand, when the same Mn(II) concentration was dissolved in surface water, the addition of $KMnO_4$, which was the molar ratio of $KMnO_4/Mn(II)$ ranged 0.67 to 0.84 was needed for the regulation satisfaction, and the dominant mechanisms were both oxidation and adsorption. Unlike Mn(II) in tap water, the increasing the reaction time increased Mn(II) removal when $KMnO_4$ was overdosed. Finally, the optimum conditions for the removals of 0.5 - 2.0 mg/L Mn(II) in surface water were both $KMnO_4$ to Mn(II) ratio is 0.67 - 0.84 and the reaction time of 15 min. This indicated that the addition of $KMnO_4$ was the one of convenient and effective methods to remove Mn(II).

  • This study aims at choosing indicators to measure the effect of utilizing biotop map, and analyzing its effect by an indicator from the perspective of performer. The Primary performance indicators are made through specialist survey using SMART. As a result, three indicators are chosen: "Discussion of the period of an environmental effects evaluation(reduced effect)", "Plan and execution of environment and ecology plan in an urban development site", "Minimizing ecological damage in an urban development." The result in each indicator is as follows. The indicator of discussion of the period of an environmental effects evaluation(reduced effect), the average reduction rate in statistically meaningful level reduced 6.08% and 11.64% respectively in 2004-2005. In this period, environment information system was established and the reduction effect is shown in this period by reinforcing environment effect estimation using biotop map. As to the indicator of utilizing biotop map in an urban development site, the Seongnam P site case shows that biotop map was used when they set up an development plan. In case of minimizing ecological damage in an urban development, the Gwangjingu G-dong case shows that it was used to appoint preservation sit, and mediate development restrict area. Accordingly, the biotop map utilizing effect is confirmed through core performance indicators and verification of the indicators using SMART. The further research is encouraged to find evaluate indicators and verify the effect quantitatively to increase the use of biotop map.

  • Comparative studies on the quality of life, a new research specialization,have emerged only in recent years and are experiencing vigorous development in many parts of the world This study is a two year phasing-in project carried out by a jointed research team between Seoul National University and Tokyo University. As the first study of the project series, the aim of the study is to learn how different the quality of life(QOL) between Seoul and Tokyo and how the students of both cities assign the relative weights to parameters of the quality of life in their cities. The study also attempts to illustrate the current state of the art in this new field. Seoul and Tokyo are located very closely bur their physical, socia-economic and cultural aspects are not the same but rather different. Here is our interest and the reason why we started out study. The study is divided into the following two principal parts: (1 ) The survey of the variables influencing the puality of life in Seoul and Tokyo (2) The survey of the attitude of students towards the relative importance of parameter of the quality of life in Seoul and Tokyo. The researches of the variables were carried out utilizing the existing official statistics derived from 1988 Seout Statistical Year Book and 1987 Tokyo Statistical Year Book. Therefore, the choice of indicators was largely limited to data that had been compiled in two yearbooks. The attitude surveys of students were carried out by interview. The questionnaire consists of a face sheet and a question which is designed to produce information on the relative importance of the parameters by the paired comparison method.

  • In this study, relationship between the air pollution of Siheung city and the relative contribution of automobiles to the city's pollution was evaluated for the first time. Then, new air pollution exposure index was developed through simulation. Using the newly developed index, two different urban development scenarios were compared to present a sustainable urban development plan to reduce air pollution from the land utilization point of view. According to the result of this simulation, air quality of the city was found to be affected significantly by human activities. More populated area showed worse level of air quality. Any development in the city resulted in more automobile activity and deterioration of air quality. This simulation result thus explains that a rapid increase of automobiles accompanied by the land development near local roadsides in the city is the major cause of air pollution in Siheung city. In this study, if urban activities are vigorous in an area with high air pollution, people are more likely to be exposed to air pollutant under the bad environmental conditions. On the other hand, if urban activities are less vigorous in an area with high pollution or if urban activities are vigorous in an area with less pollution, the environmental condition was positive. The APEI (Air Pollution Exposure Index) was developed based on these considerations. Scenarios 1 and 2 were compared and analyzed using APEI. In result, scenario 1 is the case in which land is developed and used in an environmentally favorable manner. From this study, it was proved that the impact of air pollution on human health can be minimized with proper land use. The result form the current study can be used as the basic information to solve problems from improper land utilization and air pollution (by road traffic). It also can be utilized to evaluate air pollution level according to land use and road characteristics and to help to choose the best location of land use to comply with the road function and status.
