  • It is a wrong decision to use only topographic and geological maps for the study of pediment morphology in Korea. For the study of pediment morphology it is necessary to survey the earth structure by field techniques. In Korea, pediments are mostly found in granite areas with hardrock cover. But, pediments also developed in gneiss areas and what is worse in limestone areas. So, all areas in Korea developed pediment morphology. Only in South Korea pediments show a direction from south to north or from west to east. They developed only in right angles to each other, either parallel or in right angles to the strike, depending on the bedrock structure. Pediments are found in two levels. The upper level pediments are correlated with the lower level erosion surface. Besides this pediments are found in Hoenggye-ri of the Taegwolryong area in a third level 800m above sea level. The pediments developed in basins, at the lower margins of steep slopes dividing three levels of erosion surfaces and around the residual mountains on the erosion surfaces. The first belong to the early stage of pedimentation, the second to the middle stage and the third to the last stage. Also, in Korea monadnock and residual mountain have developed the pediments are correlated the slope of the hinter mountains. Akagki states that the only pedimentation times have been times of arid climate and that they are dissected by gulley erosion with climatic change, but writer's study proves that pedimentation takes place with eustatic movement, reckless defore-station and convectional rain. These facts indicate that the landforms, geological character and process of erosional cycle of the pediments in Korea resemble much those in the Chugoku Mountains of south wertern Japan, but they are larger in scale than those in the Chugoku Mountains. In conclusion, while Akagki emphasizes the geological character and climatic change in pedimentation, the writer studies prove that eustatic movements, especially the sea level rise after the Wurm age are important factors for pedimentation. Besides this the author's studies allow a classification of gentle slopes.

  • Dissected erosional surfaces are widely distributed in the western part of Korea (e.g. Icheon, Chungju, Jecheon, Seosan). The deposits with thickness of less than 2m occur on the smooth bedrock surface are composed of poorly sorted subangular gravels with less than 20cm diameter. However, only weathered mantle of granites without the gravel layer are observed at some outcrops. The results of grain size analysis of deposits of Icheon district revealed that the characteristic of the gain size distribution is very similar with the results of sheetflood deposits presented by Blair (1999) in the Death Valley. Loess layer with buried soil layers of MIS7 covers the sheetflood deposits. The loess layer implies that the sheetflood deposits occurred before MIS7 based on the typical Loess sequences presented by Naruse et al.(2003). On the other hand, the climate of Korean Peninsula in MIS2 was very dry and cold (Yoon and Hwnag, 2003) by pollen analysis. This is because Yellow Sea was completely emerged during the MIS2(e.g. Sau\ito, 1998). So, it is thought that the climate in Korean Peninsula of not only MIS2 but also other glacial ages such as MIS8 was similar with present Mongolian climates. Tanaka et al.(2005) pointed out that Hortonian overlandflow occurs in grass vegetated granite basin in Mongolia. Therefore, dissected piedmont gentle slopes in the western Korea were possibly formed by sheetflood erosion during probably MIS8 as pediment widely distributed in Mongolia.

  • The purpose of this study is to examine the design characteristic of the facade of the main adminstration building in university. The main administration building which is a basic of educational facilities has various administration setups, such as the register's office, the student affairs section, the planing department, the general affair's office and so on. This building performs academic, administration, facilities management, and admissions service. Also, the building has an ideological, historical, and symbolic image, having an organic relationships with the other educational facilities. This study choose one hundred seven universities, except universities that does not provide information easily and the second campus which does not have the main administration building, as the subjects of the study. The analysis is derived from the design elements applied to facade design of the main administration building and this is divided into design principles(balance symmetry, contrast, rhythm), the formal composition(geometrical, linear), and the style of architecture(classical architecture and modern architecture). The results of the research are summarized as follows: The design characteristic of the facade of the main adminstration building in university has chronologically changed. First of all, in the 1940's, symmetry emphasized on the center of building, superimposition, division, pediment, and arch were marked. Then, superimposition was prominent in the 1950's and symmetry emphasized on the center of building was shown in the 1960s again. Flat roof was in the 1970's, 1990s and 2000's. Finally, pediment was dominant in the 1980's. The design elements of the main administration building can be samples of chronological styles of architecture. Facade design, with proper design of the past and recent times, includes the meaning that achieve the great purpose of the university by emphasizing visual images.

  • 이 연구의 목적은 한국의 영남지방에 있는 4개 전통취락의 입지를 지형적인 관점에서 해석하는 것이다. 이를 위해 GIS 기법을 이용하여 취락의 사면 경사도, 사면향, 하천과의 관계를 계량적으로 분석하였다. 특히 전통취락의 입지에 담겨있는 풍수적 사고와 택리지의 복거론적 지형인식이 현대의 지형분석적 입장에서는 어떤 의미를 가지며 그것이 시사하는 점이 무엇인지를 검토해 보았다. 그 결과 유곡은 계곡분지의 산록부 천전은 구룡지 말단부에 입지한다. 하회는 곡류하천 범람원의 볼록한 자연제방에 입지하고, 양동은 구릉지에 입지하고 있다. 가옥들은 대체로 남향과 남동향, 남서향이 많지만, 하회는 모든 사면으로 분포하는 것이 특징이다. 또한 4지역은 하상비고 $10{\sim}20m$ 범위에 입지하는데, 이 하상비고는 수해에 대비한 안전고도임을 알 수 있다. 이처럼 과거 풍수적 관점에서 명당이라 지칭해 온 영남지방 4대 전통취락의 입지는 현대의 주거입지론적 측면에서도 우수한 지형조건을 갖추고 있는 것으로 판단된다.

  • Koreans have regarded the red as a major color from old times. The red is a traditional color to have symbols of high position, national foundation and especially royalty. So, we can see the reds in the palace for kings very much.The purpose of this study is to draw out the features of color red in the Kyungbok palace. The color was analyzed by two categories-architectural buildings${\cdot}$structures and ornamental painted patterns. The major findings from this research are summarized as follows:1. Seokganju(similar to terra rossa) and toyugsaek(light seokganju) are found main colors in architectural space, while seokganju has a linear effect and toyuk has a facial effect. 2. Yugsaek(similar to light vermillion) and Jangdan(similar to orange) are found main colors in ornamental painted patterns. These colors are more vivid and brighter than those for architectural space.3. As for two-color combination, reds and blues(including greens) are found major combination both of architectural space and ornamental patterns. And reds and white are the following combination, which gives an bright image by white. 4. As for three-color combination, red-white-black combination of pediment and red-blue-white combination of openings are found very popular in architectural space, while red-blue-yellow combination is most popular in ornamental patterns.The reds are found dominant color of both architectural space and ornamental patterns in the Kyungbok palace. The color design as shown in the Kyungbok palace can be considered as the feature of traditional color design.

  • The purpose of this study is to examine the characteristics of space design appearing in facade and interior composition factors of buildings in the colonial period in Indonesia. Research method is a field study, and subjects of the study is 14 buildings built in the colonial period located in Jakarta. The research result is as follows. First, Facade is divided into C type (colonial style), CT type (colonial style + traditional style), CA type (colonial style + art deco style), and CTA type (colonial style + traditional style + art deco style). Among them, CT type which shows both a colonial style and traditional style accounts for the most. As for Java traditional style mainly shows Joglo roof style and bratticing decoration on top of gates, and the colonial style presents both an Amsterdam canal housing style such as narrow Facade and unusual Gable, and a classical style such as pediment, entablature, and columns. Second, interior space is divided into C type (colonial style), CT type (colonial style + Indonesian traditional style), A type (art deco style), and CA type (colonial style + art deco style). Among them, CT type was also accounted for the most. Selected traditional style is a shape of bratticing decoration on top of gates and a shape of tenon of Joglo housing structure. Colonial style showed classical style such as exposed crossbeams, columns, and pilasters, and as for unique decoration, there are Ancona decoration and Delft tile decoration. On one hand, art deco style used typical art deco factors such as contrast of various materials and complementary color or golden color use as well as zigzag or vertical lines and geometric ornament by combining with colonial style or traditional style. It is expected that such research result will be a practical reference data when Korean construction companies or interior design companies advance Indonesia.

  • 황해 남동해역에서 채취한 97개 표층퇴적물을 대상으로 그 지화학적 특성을 규명 하기 위하여 철, 망간, 니켈, 구리 및 납의 5가지 금속원소 함량과 아울러 퇴적물의 입도와 탄산염 함량 등이 분석되었다. 분석된 금속원소 중 니켈과 구리는 퇴적물 입도 와 밀접한 상관관계를 나타내어 그 공간적 분포는 입도분포와 유사하게 나타났다. 이 와는 대조적으로 망간과 납의 경우는 입도와의 관련성이 미약하였으며, 전반적으로 한 국 연안에 인접한 시료에서 높은 함량이 나타났다. 한편, R-mode 요인분석 결과도 니 겔과 구리의 함량을 조절하는 요인이 망간이나 납의 함량을 조절하는 요인들과 구별됨 을 보여주었으며, 금속원소의 행동과 분포에 있어 이렇게 상반된 결과가 나타나는 현 상은 퇴적후 속성작용 및 환경오염물질 유입의 영향에 기인한 것으로 해석되었다. 이 에 근거하여 이들 금속원소들의 비가 서로 다른 기원의 세립물질들을 구분하는 특징으 로 이용될 수 있는 가능성이 제시되었다.
