The primary focus of this study is to provide a general methodology which can be utilized to understand and analyze environmental issues such as long term ecosystem dynamics and land use/cover change by development of 2D dynamic landscape models and model-based simulation. Change processes in land cover and ecosystem function can be understood in terms of the spatial and temporal distribution of land cover resources. In development of a system to understand major processes of change and obtain predictive information, first of all, spatial heterogeneity is to be taken into account because landscape spatial pattern affects on land cover change and interaction between different land cover types. Therefore, the relationship between pattern and processes is to be included in the research. Landscape modeling requires different approach depending on the definition, assumption, and rules employed for mechanism behind the processes such as spatial event process, land degradation, deforestration, desertification, and change in an urban environment. The rule-based models are described in the paper for land cover change by natural fires. Finally, a case study is presented as an example using spatial modeling and simulation to study and synthesize patterns and processes at different scales ranging from fine-scale to global scale.

As recent inflows of foreign immigrants to relatively advanced countries in Northeast Asia have rapidly increased, Japan in particular uses 'multicultural coexistance' as a key concept for developing both discourse and policies on them. This paper is first of all to suggest a new typology of multicultural societies in the world ill order to differentiate the case of Northeast Asian countries from those of Western countries. And this paper is to suggest that foreign immigrants in Japan have different positions in labor markets and living experiences according to historical and social backgrounds as well as their nationality. The transformation process towards multicultural society is not only historical and social but also geographical and spatial, as foreign immigrants have made different spatial distribution and regional segregation in types. In order to control this socio-spatial process towards multicultural society, Japan has developed the concept of 'multicultural coexistence' similar with that of multiculturalism in Western countries. This concept seems to be quite significant as it has been initiated by local communities for symbiotic relationship between foreign immigrants and native Japanese dwellers. But it can be regarded as a strategic ideology to control foreign immigrants as it targets mainly on Nikkeijin, and is usually concerned with the cultural aspect. Seen from a theoretical point of view, this concept can be seen as closed with liberal multiculturalism as opportunity equity, but far from corporative multiculturalism as outcome equity, and it is on the process transferring from the first stage of tolerance to the second stage of legislation of nondiscrimination, while being distant from the third stage of legislation paradigmization of recognition, and hence appears to be easily reverted to assimilationism.

Conventional methods for the assessment of liquefaction potential were primary for severe earthquake regions $(M{\geq}7.5)$ such as North America and Japan. In Korea, an earthquake related research has started in 1997, but most contents in the guidelines were still quoted from literature reviews of North America and Japan, which are located in strong earthquake region. Those are not proper in a moderate earthquake regions including Korea. Also the equivalent uniform stress concept (Seed & Idriss, 1971) using regular sinusoidal loading which is used, in a conventional method for the assessment of liquefaction potential, can't reflect correctly the dynamic characteristics of real irregular earthquake motions. In this study, cyclic triaxial tests using irregular earthquake motions are performed with different earthquake magnitudes, relative densities, and fines contents. Assessment of liquefaction potential in moderate earthquake regions is discussed based on various laboratory test results. From the results, screening limits in seismic design were re-investigated and proposed using normalized maximum stress ratios under real irregular earthquake motions. Also from the tests using constant wedge loading and incremental wedge loading, the characteristics of liquefaction resistance of saturated sand under irregular ground motions are investigated.

Facing reconfiguration of world economic order in the process of globalization and changes in domestic economic and social conditions, Japan has experienced a rapid inflow of foreign immigrants and hence a restructuring of labor market and ethic and cultural mixture. This paper explores contexts of inflow and social and spatial characteristics of immigrant workers in Japan. Uneven regional development on the global level and shifting to flexible accumulation regime, depletion of previously underutilized labor resource, better-educated youth and shrinking and aging of Japanese populace on the national level can be pointed out as important elements of immigration contexts. This paper also explains the hierarchizaton of labor market and differentiation of spatial distribution of immigrant workers in Japan in terms of visa condition and nationality. In particular, focusing on the case of Hiroshima prefecture, this paper analyzes residential differentiation of immigrants according to their nationality. Finally, it finds out some problems which immigrant workers have confronted in Hiroshima region.

우리나라 가뭄의 지역적 특성은 수문학적으로 동질한 지역의 구분 결과에 따라 달라진다. 지역의 구분에는 가뭄에 영향을 미치는 다양한 변수들이 사용될 수 있다. 가뭄을 특징짓는 요소로서 지속기간, 심도, 이외의 통계적 특성들이 있으며, 이 변수들을 정보화하여 변수의 유형을 구분지어 모든 변수들을 요약된 정보로 활용하여 가뭄의 특성을 구분할 수 있다. 본 연구에서는 우리나라 기상청 강우자료 75개 관측지점 중 30년 미만의 강우기록이 있는 17개의 지점을 제외한 58개 강우 관측 지점을 대상으로 가뭄지수(SPI)를 산정하여 가뭄사상의 특성을 정량화 과정으로 남한지역 가뭄특성을 분류하였다. SPSS를 활용한 다변량 분석기법인 주성분 분석(principal component analysis)을 통해 가뭄특성인자의 상관관계가 높은 변수들을 조합하여 그 변수들 중 가뭄정보를 가능한 많이 함축하고 있는 새로운 특성 변수를 만들어 내었으며, 선정된 변수들을 바탕으로 요인분석(factor analysis)의 직각회전 방식(Varimax)을 이용하여 변수들의 표준화를 통해 가뭄특성요인을 찾아내었다. 이를 통해 지역간 동질성을 파악하여 K-means기법을 적용하여 군집해석(clustering analysis)을 실시하였다.

The aim of this paper is to grasp the impact of entrepreneurial activities of politician and business owner on regional industry amid the rising importance of entrepreneurship as the driver of structural change. In particular, it would help narrow the knowledge gap in empirical research by analysing the entrepreneurial spirit and motivation of the different trait of politicians and entrepreneurs that the relevant research is still insufficient. Through the case of politician' and business owner's entrepreneurship on the carbon industry growth of Jeollabuk-do and innovative start-up entering the lagging textile industry of Daegu, this study unearths the necessity of entrepreneurship, which has not been considered relatively much in the process of establishing regional industrial policies, thereby drawing the policy implication.

SPI지수는 강수량이 감소하기 시작하면 필요한 물수요에 비해서 상대적으로 물부족을 유발하게 되고, 가뭄발생의 발단이 된다는 것에 착안하여 개발된 지수이다. 하지만 다른 가뭄지수와 마찬가지로 강수량 또는 유출량 시계열을 상대적인 표준정규분포로 산정하였기 때문에 인근 지역에 비해 상대적으로 강수량이 많은 지역도 실제로 발생하지 않은 가뭄이 발생한다고 분석이 된다. 이러한 현상을 완화시키기 위해 수정된 가뭄분석 기법이 요구된다. 이에 Jeung et. al(2019)은 이런 현상을 완화시키기 위해 SPI지수 계산과정에서 해당지점의 시계열을 대상으로 계산되는 Gamma 분포를 전국으로 확장 시켜 산정 후 표준정규분포에 적용하여 가뭄지수를 산정하였다. 또한 과거 제한급수가 발생했던 지역을 대상으로 극한가뭄과 가뭄지속기간을 이용하여 M-SPI지수의 효용성을 확인한 결과, 제한급수 실시년도와 SPI, M-SPI 결과와의 비교결과 과거 가뭄을 정확하게 모사하는 것을 확인하였다. 하지만 M-SPI는 전국을 하나의 지역으로 가정하여 산정하였고, 증발산량과, 고도 등 지형의 특성을 고려하지 않았기 때문에 일부의 가뭄사상을 재현하지 못하였다. 이에 본 연구에서는 기상학적 인자와, 지형학적 인자를 고려하여 지역화를 하고, 각 지역별로 대표 확률분포를 산정하여 가뭄지수를 산정하고자 한다. 또한 한국 기상청에서 제공하고 있는 국가 표준기후변화 시나리오를 수집하여 M-SPI에 적용하여 미래 극한 가뭄빈도의 변화를 전망하고자 한다.

Globalization of economy has a significant impact on the organization of economic Space. This paper examines the concepts of globalization and localization, major trends of the changes in the organization of economic space in the Pacific rim, and the major processes of the changes. Intra-regional trade and foreign direct investments have increased considerably in the Pacific region with the progress of globalization during the last decade. Due to the Progress of globalization of economy in the Pacific rim, some growth triangles have extended their agglomeration area beyond the national boundaries and several new industrial districts have developed. The reorganization of the economic space in the Pacific rim has been resulted from industrial restructuring of NIEs, spatial division of labor along the commodity chains, and the formation of industrial networks within the region. The ‘cooperative network strategy’has been suggested to minimize the negative effects of glocalization and for the sustainable development in the Pacific rim.

Many of the old industrial cities in advanced economies have experienced deindustrialization since the 1960s. While some of them have been transforming their economic structures with new economies, such as arts and cultural industries, others have been seriously suffering from economic and social problems. Brooklyn Borough of New York City is one of the best examples which have gone trough rapid de-industrialization; but have been reasonably successful in recovering its economy with arts and cultural industries. This paper introduces the process of developing creative industry clusters, articulates major actors, and find out the governance of the clusters, using three Brooklyn's arts clusters, such as DUMBO, BAM and Williamsburg. Based on the case studies, the paper draws theoretical and policy implications applicable to the Korean circumstance.
