The purpose of this paper was to compare and analyze the elementary curriculum and textbook integration of social studies in Korea, USA, and England in terms of content integration and to make suggestions for the improvement of Korean social studies curriculum and textbooks. For this study, social studies curriculum and textbooks of three different countries were analyzed according to the three criteria: sequence, types and focus of integration. In this comparative study, five suggestions were made for the improvement of the Korean elementary social studies curriculum and textbooks. First, Korean social studies curriculum should have a subject focus at each grade level. Second, it is recommended that Korean social studies curriculum should present clear interrelations among geography, history, and civics at each grade level. Third, Korean social studies curriculum needs to have diverse criteria on which to select and organize themes. Fourth, Korean social studies textbooks need to have increased number of interdisciplinary large units. Fifth, it is necessary that the authors of Korean social studies textbooks integrate contents in consideration of students' life context in order to raise the relevance of the contents of history and geography.

Background: The cancer research literature suggests that women, especially premenopausal women, have lower cancer mortality rates than men. However, it is unclear if that is true for populations at all age levels in all countries and what factors affect such sex differences. This paper attempts to fill that gap. Materials and Methods: Sex- and country-specific cancer mortality data were statistically analyzed with particular attention to geographic, social, and economic factors that may affect the sex differences. Results: The sex differences were age and country specific, rather than universal. Premenopausal women actually tend to have a disadvantage compared to men or postmenopausal women. Male cancer mortality appears to be the affecting factor in explaining variations in sex differences. Latitude of residence and literacy rate are the affecting factors in cancer mortality and sex differences. African and Latin American countries tend to have a female disadvantage, while East Asian and Eastern European countries are more likely to have a female advantage. Conclusions: The findings challenge the cancer mortality literature and indicate that the sex differences and their possible causes are more complicated than the current literature suggests. They also highlight the urgency of adapting age- and country- specific health systems and policies to better meet the needs of younger women.

This study tries to reveal transport mechanism and origin of components from fluvial terrace deposits in Danyang and Geum River basins, through grain size partitioning using the Weibull function. Grain size parameters suggest that the samples analyzed in this study can be grouped into the coarse, fine and medium samples. The coarse samples are partitioned into three or four components. More than 65% of the coarse samples consist of components by suspension and saltation by fluvial process, while components by attachment to coarse grains or aggregates and/or by individual grains deposited under non-flow condition are also found in the coarse samples. The fine samples consist of four components and components found in loess deposits in Korea occupy >70%, suggestive of the same transport mechanisms (westerlies and winter monsoon) and common source areas with loess deposits in Korea. However, components by aeolian process from local sources as well as by fluvial process are also found in the fine samples. The medium samples are partitioned into components with similar sizes to the coarse and fine samples, respectively.

This study tries to reveal source areas of fluvial terrace deposits in Danyang and Geum River basins located in the northern and southern parts of the Sobaek Mountains, respectively, through geochemistry. The samples analyzed in this study show different grain size properties and can be grouped into the coarse, medium and fine samples. Grain size properties suggest that the coarse samples are typically fluvial deposits and geochemistry from the coarse samples is also similar to that from the bedrocks within the basins. The fine samples show geochemical properties different from the bedrocks and similar to loess deposits in Korea. However, different geochemical concentrations among the fine samples can be also recognized, indicating mixtures of loess materials with weathering products of the bedrocks. One sample among the medium samples is considered as fluvial deposit due to geochemical similarity to the bedrocks, while geochemistry from another sample among the medium samples indicates that loess materials were mixed with more abundant weathering products of the bedrocks than those in the fine samples.

본 연구에서는 전공 교사와 비전공 교사에 의한 지리 수업의 차이점과 비전공 교사에 의한 지리 수업 운영의 문제점을 분석하고자 2003년 4월과 5월에 서울의 3개 중학교에서 이루어진 4개의 지리 수업을 관찰하였다. 수업 분석 내용은 (1) 수업의 조직, (2) 교사와 학생간에 이루어지는 대화의 이동 양식, (3) 수업 방법이다. 수업 관찰 이후에 해당 학교의 사회과 교사들과 면담을 통하여 비전공 교사가 지리를 가르칠 때 어려움과 해결 방법 등에 관련된 자료를 추가로 수집하였다. (중략)

This study analyzed the characteristics of spaces to and from which middle school students transfer, especially centering around the school districts of Southern area in Gyeonggi Province such as Suwon, Osan, Yongin, and Hwaseong. This study was conducted to provide the suggestions regarding educational policies such as the positioning to appropriate school districts, improving of educational environment, and implementing of educational equity, by analyzing, based on the empirical data, the educational spaces of four cities showing rapid population growth due to recent suburbanization. The characteristics of distribution of variables such as schools for each district affecting the student transfer, housing development, and socioeconomics in the research object region are mainly analyzed through the correlation analysis, multiple regression analysis, and cluster analysis. As a result, there is shown a distinct spatial difference between school districts of the cty downtown and urban fringe, and between school districts of the conventional cities(cities that have been from the past: note of translator) and new land development regions. First, the school districts in the city downtown showed lots of transfers between neighboring school districts, while the school districts in the urban fringes showed transfer-out tendencies strongly. Second, it was the new land development regions where the transfer-in rate is the highest in the Southern area of Gyeonggi Province. Third, the said new land development regions required the supply of educational installations and educational support that can meet educational demands, since these regions have relatively lower qualitied educational environments compared to the conventional cities where the fluidity of students is lower. Fourth, in the summary of all of the said three results, the student transfer in the southern area of Gyeonggi Province was shown in the spaces centering around the multi-core area by reflecting the restructuring of suburban area.

In Japan for protecting the slides of steep sloped areas covering the face of slopes by sprayed mortar became popular since 1970s. But, these mortar walls are getting older now. In this background, this study aims to find ways to develop a diagnostic technique of these faces of slope without physically contacting or destroying them. In doing so, we have used heat infrared imaging processing method and developed a simulation model to predict the weak portion of the wall. The results revealed that, by following the model vacuum of mortar wall can be detected having thickness up to 15cm.
