This article focuses on geo-institutional differentiation and a multi-scalar analysis of emerging capitalist development in Laos. It discusses the impact of the Greater Mekong Subregion on new institutional economic and economic geographical arrangements. It demonstrates the usefulness of the varieties of Asian capitalism approach. The rubber industry was chosen to unravel emerging but various sub-national institutional arrangements linked to higher scale levels. Rubber is a growing agribusiness industry throughout the country, led by the insatiable demand from China. Overall, this study shows that the capitalist development of the rubber industry features much geo-institutional differentiation, due to the different strategies of Chinese, Thai and Vietnamese investors. Since Laos is still in transition from a state-led economy to something else, it is impossible at this to identify the exact number capitalisms. Yet, the evidence on rubber clearly lays bare the presence of multiple institutional arrangements. Without more inclusiveness, however, the implications for regional development are worrying. Exclusive arrangements will most likely lead to more uneven regional development and higher regional inequality. To refine theories on sub-national varieties of capitalism in developing countries it is instructive to consider more explicitly the notion of regional personal capitalisms and the complex interplay between national and regional states and relationships between capital accumulation and livelihood analyses.

For the design of infrastructures controlling the flood events at ungauged basins, this study tries to find the regional flood frequencies using peak flow data generated by the spatial extension of flood records. The Chungju Dam watershed is selected to validate the possibility of regional flood frequency analysis using the spatially extended flood data. Firstly, based on the index flood method, the flood event data from the spatial extension method is evaluated for 22 mid/smaller sub-basins at the Chungju Dam watershed. The homogeneity of the Chungju dam watershed was assessed in terms of the different size of watershed conditions such as accumulated and individual sub-basins. Based on the result of homogeneity analysis, this watershed is heterogeneous with respect to individual sub-basins because of the heterogeneity of rainfall distribution. To decide the regional probability distribution, goodness-of fit measure and weighted moving averages method from flood frequency analysis were adopted. Finally, GEV distribution was selected as a representative distribution and regional quantile were estimated. This research is one step further method to estimate regional flood frequency for ungauged basins.

There is an increasing need to foster new industries at the local level. This study aims to analyze the spatial patterns of new industries in Korea from 2007-2017 and to figure out its determinants of agglomeration in 2017. Through this study, it is found that new industries are unevenly distributed around Seoul Metropolitan Area(SMA). The regional disparity between SMA and non-SMA is prominent. Furthermore, new industries represent a strong spatial positive autocorrelation, showing a strong concentration on a few regions in Korea. This study explores the determinants on agglomeration of new industries with spatial statistical model. From the results of spatial error model, it is indicated that the number of graduate students, the ratio of technology based start-ups, and the number of elementary, middle, and high schools have a significant effect on new industries. In addition, the specialization and the diversity of industrial structure on knowledge-based manufacturing industries and knowledge-based service industries have been statistically significant. This study provides implications that non-SMA needs policies with respect to attracting talented people, developing human resources, and improving regional environment in order to improve regional competitiveness in promoting new industries.

This paper deals with the regional asymmetries of MERCOSUR and regional development cooperation for its solution. Through the formation of a common market, the countries of Southern Cone expected to grow evenly. However MERCOSUR had structural asymmetry from the beginning and exposed policy asymmetry over time. It is basically due to the overwhelming influences of Brazil on MERCOSUR. With regard to asymmetries, Paraguay calls for special and differential treatment. Uruguay wants equitable application of market liberalization. Argentine emphasizes production integration based on the development of value chains. In the issue of asymmetries, while Paraguay, Uruguay and Argentine act as petitioners, Brazil is capable of selecting the initiatives. Under these circumstances MERCOSUR has established FOCEM as regional redistribution mechanism. FOCEM has achieved some results as seen in Paraguay, but there are still problems such as financial limitations and lack of enforcement. In oder to activate the redistributive mechanism for regional integration and to coordinate the policies to resolve regional disparities, transnational governance is essential but all member countries are reluctant to it. To date, regional asymmetries or development gaps have persisted and disparities in individual countries remains a problem.

A batch experiment of pyrite oxidation was performed and the surfaces of the reacted pyrite were regularly observed with the scanning electron microscope (SEM) together with the chemical compositions of the solution to help understand the oxidation mechanisms of pyrite by Acidithiobacillus ferrooxidans (Af). The dissolved Fe concentrations clearly indicated that Af experiences the lag and then exponential growth phase. An Af cell was observed to be attached to the surface of pyrite during the lag, implying that a direct leaching by the microbe really happens for the period. It is not certain, however, whether the main mechanism of pyrite oxidation during that time was the direct leaching or not, because there were just a few cells confirmed to be attached and most of the dissolved Fe was Fe(III). The dissolved Fe concentration stayed almost constant from the mid-lag phase to just before the onset of the exponential phase, suggesting that AI needs an adaptation time to switch its oxidation mechanism from one to the other whichever it is during that stage of growth. The moment of Af's cell division was observed by SEM on the surface of pyrite during the lag phase. The corrosion outline around the dividing cell was quite similar to the shape of the cell itself, which implies that the rate of the microbial oxidation is very uneven and the rate when the cell metabolizes should be much faster than that calculated from the concentration variation of the dissolved Fe. The number of etch holes by Af is much higher on the inoculated surfaces, indicating the average rate of pyrite oxidation is also much faster than that of abiotic oxidation. The microbial etch holes on pyrite surface are small and deep, which may influence the transition of the growth phases of Af from lag to exponential.

The assessment (or the evaluation) of spatial disparity is the main concern for the study of spatial disparities or spatial inequalities. In order to evaluate the spatial disparity, the regional differences have to be counted quantitatively. Several measurements have been introduced for evaluating the development potentials of each region. Most of them are the composite indices of the socio-economic variables rather than the real potentials of the region. This study attempts to investigate the spatial disparity in Korea. For the purpose, the levels of opportunity potentials of the cities have been calculated by the Potential Model redefined by Lee(1995). The opportunity potentials have been calculated for the educational, cultural, medical service, environmental sectors, income, and consumption sectors, and the spatial patterns of various opportunity potentials have been analyzed. The spatial patterns of opportunity potentials show the severe concentration on the Metropolitan Seoul area through all sectors. The next level concentration appears at the other end of the Keuyng-Bu axis. And the cities relatively high opportunity potential values are distributed along the Keuyng-Bu axis. Remain parts of the country show quietly low opportunity potential values. In particular, the southern-west and the northern-east parts show relatively very low values. This pattern appears for all sectors except for the opportunity potential of the environmental sector. It means that the spatial disparity in Korea have been promoted and enhanced by the national development policies concentrated the investment on the large cities along the Keuyng-Bu axis during the last 40 years.
