This study aimed to develop and to apply the CPS model using Creative Problem Solving (CPS) model as a class method for enhancing creativity in the field of Geography and to analyze the results. The class was developed using the CPS model, specified in six stages as the basic model by Treffinger and others. Class was held in two sessions, after which effects of the class such as change in the students’ creativity, satisfaction level towards class, and attitude towards curriculum were verified. This study’s results demonstrated that the students’ creativity increased after conducting the CPS model. Students gained the opportunity to think about the solutions in a creative manner while participating in the CPS class and they found the class interesting. Moreover, students’ level of understanding towards the environment issue increased, and they though that they participated in the class with greater interest compared to the existing lecture type of class. After the CPS model, students perceived that Geography can help to solve problems that afflict individuals or society, and that they can improve their creativity through the Geography class.

The purpose of this study is to examine the spatial patterns of monthly extreme precipitation events across the Republic of Korea based on daily precipitation data for the period of 2002~2011 observed at automatic weather systems (AWS) and Automated Synoptic Observation Systems (ASOS) under the supervision of the Korea Meteorological Administration. According to time series analyses, the number of stations with extreme precipitation events exceeding 80㎜ of daily total precipitation increases with the onset of summer Changma, forms its major peaks in mid-July and noticeably decreases with the offset of climatological summer in mid-September. Spatially, relatively high frequency of extreme precipitation events is observed in Jeju Island and southern coastal regions of the Korea Peninsula between late spring and early summer associated with migratory low pressure systems, while such patterns appear everywhere with the onset of summer Changma including central regions. In particular, noticeable high frequency of extreme precipitation events is observed in Mt. Halla, southern coastal mountain regions, southern flank of Mt. Jiri along the Sobaek mountain ridges, northern mountain regions in Gyeoggi province and along the Taebaek mountain ridge. In contrast, relatively high ratio of cumulative extreme precitation to total precipitation appears in interior regions where annual total precipitation is relatively small. These results indicate that the interactions between topography and moisture advection by migratory lows, Changma front and typhoons are crucial to the spatio-temporal patterns of extreme precipitation events in the Republic of Korea.

The purpose of this study is to produce a Synthetic Deprivation Index (SDI); using AHP for logical and systematical synthesis of various criterions on urban deprivation with analyzing spatial patterns of synthetic urban deprivation and further exploring the dynamics of spatial pattern of urban deprivation. There was not a consensus of definition for Urban Deprivation. It means that criterion and perspectives could be different in time and region. According to the various existing research on urban deprivation, huge cities are experiencing problems of prevailing and multiple deprivation in diverse areas. So, Analytic Hierarchy Process (AHP) was applied to explore urban deprivation and the output has named the Synthetic Deprivation Index. The object region for this empirical study is Seoul. The regional scales are Gu and Dong. The periodical scales are 1998 and 2008. First, by using 2008’s Gu scale data the output of applying AHP can be compared and non-applying AHP to search the meaning of using AHP for urban deprivation. Second, search out the urban deprivation dynamic through the exploring urban deprivation spatial pattern change from 1998 to 2008. Third, the difference of the Gu scale deprivation pattern with Dong scale deprivation pattern is analyzed. Variables for assessment of urban deprivation were selected on the basis of preceding studies, especially location quotients are useful to reflect spatial convergence of specific nature. As a result, AHP is useful to reflect relative importance among many criterions, especially in the application of detecting urban deprivation spatial patterns. Chronicle analysis shows that more deprived areas positioned northern part of Seoul and the center of deprivation moved toward north. Finally by comparing between different regional scales, I found that deprived Dongs spread over the whole part of Seoul, most especially the northern part and the border area of the Seoul city.
