This study aims to examine various discourses of the urban landscape discussed in the fields of new cultural geography, spatial political economy, and landscape architecture in order to propose a theoretical framework for the interpretation of a contemporary urban landscape. The notion of landscape is a modern idea that separates humans, especially the bourgeois subject, from nature, and then achieves the visual possession of nature. New cultural geographers have studied the political aspects of landscape. According to them, landscape as materialized discourse is "a way of seeing" which includes the vision of the upper class, the imperialistic view, and the masculine and voyeuristic gaze. In addition, spatial political economists have paid attention to the economic aspects of landscape. They have emphasized that the material production of landscape is indispensable in the production of surplus values in the capitalistic system. Thus, we insist focusing dialectically on both the materiality and ideology of landscape.

The aims of this study are to clarify the geomorphological development of a alluvial plain and discuss the vegetation environments and agriculture activities in the Wangpo-River alluvial plain at Neungsan-ri, Buyeo by analyzing geomorphological classification, sedimentary facies and age datings. The alluvial plain at Wangpo-River was formed by the influences of Geum-River with the sea-level rising during the Holocene. The basin of Wangpo-River consists of natural levees, back marsh-type alluvial plains, valley plains and hills. The natural levees by Geum-River largely distributes at the area where Wangpo-River flows to Geum-River and the alluvial plains at the middle and lower reach are the back marsh areas of Geum-River. Moreover, the area along Wangpo-River show higher contents of coarse materials and thinner peat sediments than the back marsh. The lower sandy deposits in the alluvium of Wangpo-River was formed with the influences of human in the Bronze Age during the sea level falling and the peaty deposits was formed due to the water level rising of Wangpo-River during the sea level rising in the early Iron Age.

Integration of GIS data and human expert knowledge into digital image processing has long been acknowledged as a necessity to improve remote sensing image analysis. We propose inductive machine learning algorithm for GIS data integration and rule-based classification method for land cover classification. Proposed method is tested with a land cover classification of a Landsat ETM+ multispectral image and GIS data layers including elevation, aspect, slope, distance to water bodies, distance to road network, and population density. Decision trees and production rules for land cover classification are generated by C5.0 inductive machine learning algorithm with 350 stratified random point samples. Production rules are used for land cover classification integrated with unsupervised ISODATA classification. Result shows that GIS data layers such as elevation, distance to water bodies and population density can be effectively integrated for rule-based image classification. Intuitive production rules generated by inductive machine learning are easy to understand. Proposed method demonstrates how various GIS data layers can be integrated with remotely sensed imagery in a framework of knowledge base construction to improve land cover classification.

Records on natural hazards such as droughts, floods, smallpox and attacks of grasshoppers are classified and analyzed during the Ancient Times(BC 57$\sim$AD 935) based on the Historical Records of the Three Kingdoms Age(Samguksaki main record), and influences on human activities and relationships of each natural hazard are studied. The strongest influences on the agricultural productivity were the drought and the influences of floods were weak. The most floods were not destructive hazards because the cultivated lands were distributed in the valley plains and the towns and villages were constructed in the area free from the floods during the Ancient Times. The attacks of grasshoppers have the high frequencies with the droughts. The smallpox of the Ancient Times has no relationships with the dearth, floods and droughts. This means that the waterborne infections happened periodically and after the unification, the infectious diseases happened continuously due to the urbanization leading the concentration of population on the capital. Two cycles of droughts are recognized, and they happened with the time intervals of approximately 500 years during approximately 1000 years in Shilla dynasty.

This study investigates and proves the historical facts about the confidential land survey on Korean peninsula made by Japanese intelligence officers at the end of Chosun Dynasty. Under the command of general staff office of Japanese army, the military officers produced several maps through road map measurements and visual measurements. Although previous literature indicated road map measurements on Korea were originally implemented from 1885, this study confirms that road map measurements were initiated in 1882 by a lieutenant Isobayashi. Reflecting secret map making procedures, the individual military intelligence officers had specialized roles for swift information collection and map production.

Most of previous landform classification methods using DEM compares the values between the center of the cell and the surrounding cells, which in turn, greatly depends on analysis scale. To overcome the problem of scale-dependency, a new classification scheme is developed, which is called "Geomorphons". Unlike the traditional approaches using DEM, Geomorphons is the way which compares the level with other cells against the criteria cell. As a pilot study, we classify the landforms of Pyeongchang-Gun in Korea. Then, we compare the result with the other methods such as Topographic Position Index. Through the systematic analysis, we obtain the following findings. First, Geomorphons can reduce the time for the classification of landforms because of using unsupervised classification. Second, Geomorphons is little dependent on change in the scale, which can provide a pilot tool for reconnaissance study for covering large area.

Texas has recently emerged as a phenomenal industrial destination, which attracts headquarters, production facilities, and/or regional centers of global corporations including Tesla and Samsung. Known as "Texit", this trend of corporate investment to Texas has concentrated in highly developed industrial clusters (such as Dallas-Fort Worth, Houston, Austin, and San Antonio) since the early 2000s. Against this background, this paper examines sectoral and geographical characteristics of those clusters, and investigates associated state initiatives that have been introduced and implemented. As a result, key policy measures in the state are found to be aligned to free-market liberalism, diversified incentives, and regional specialization. Unlike Silicon Valley where Bohemian liberalism engendered vibrant entrepreneurship and innovative start-up formation, it is the strong state government that leads industrial cluster upgrading in Texas, while successfully harnessing lower income taxes and deregulation, affordable land and infrastructure, and quality higher education and human capital as regional assets for attracting inward investment.

This study analyzed problems of interpretive signs along Eorimok-Yeongsil Trail on Mt. Hallasan National Park, focusing on factors of distracting visitor's attention from reading and understanding the signs. Eorimok-Yeongsil Trail has a total of 86 signs, and according to their purpose and content, they are classified into thirteen general signs, sixteen location signs, nine safety signs and forty-eight interpretive signs. Interpretive signs provide visitors with information and explanations about the nature and human resources of Mt. Hallasan as well as enhancing the opportunity for self-guided interpretation. The contents of interpretive signs of Eorimok-Yeongsil Trail are composed of landscapes, flora and fauna, topography, geology, history and culture, of which 70.8% of the total are related to plants and animals. Interpretive signs on the Eorimok-Yeongsil Trail do not attract visitors' attention because of the low readability, inappropriate locations and frequent errors in translation from Korean into other languages. The causes of low readability of interpretive signs include thirty-six physically damaged and faded signs, twenty-two improper font sizes and misuse of color schemes and five unclear description signs. The reasons for the incorrect locations include twenty-two long distances from the trails, twenty-one inadequate heights and fifteen inconsistencies in descriptions and locations. Problems with English use include eight grammar and spelling errors, twenty-one incorrect translations, and twenty-six English names missing.

Remarkable development of sand bars is an important characteristic of fluviatile landform of Korea. Their development owes, in one part, to the supply of abundant sandy materials to river valley floor, originated from the weathering of essentially granitic rocks, distributed almost all over the country. It owes, in other part, to river valley disposition presenting many angular sinuosity guided by fracture grid, impeding regular migration of sandy materials along valley floor. Besides, high amplitude of river discharge fluctuation of the country plays is proved to be favorable hydrological factor for the development of the sand bars. The sand bars play important roles in favor of river hydro-ecological environment. They mitigate the amplitude of discharge fluctuation regime. In flood spell, sand grains in the main channel migrate so as to broden wet section. At the spell of low water level, they newly accumulate as to impede rapid stream discharge. Especially high quantity of reserved water in porous space of sand bar is preciously available both for human livelihood and for ecological environment.

Sasang constitutional medicine was born on basis of constitutional cognition in Korean History. Only if we look at Sasang constitutional medicine on the environment of korean unique culture, geography and historical tradition, the true feature come into view, and on the contrary we could grasp to which degree it has general properties. Sasang constitutional medicine pursue inner principles of human being, that has been the most important traditions of Korean medicine. Also that properties are results of continuous confirming academic universality and constant efforts to look for the medicine that is most fit to clinical practice. For the purpose of developing world medicine, we must grow that specific characteristics of Sasang constitutional medicine.
