When greenhouse gas mitigation policies are implemented, energy intensive manufacturing industries are influenced much due to an increase in cost. However, industries that have price setting power are damaged less by the policies. Therefore, this paper analyzes vulnerability of energy intensive manufacturing industries to the policies by measuring price setting power of the industries. We analyzed price setting power model through ECM, employing the import prices and wages as independent variables. The industries that their prices react to import prices are price takers, which their prices are determined by rival's ones. On the other hand, the industry that their prices react to wages that mean domestic cost are price setters, and they will be less vulnerable to the policies. In addition, fluctuation of energy prices would be reflected in import prices because it influences other countries than my one. Thus, we employed energy prices as control variable to measure the net effects of import prices. As empirical results, petroleum products, chemical products, non-metallic mineral products, textiles, and motor vehicles sector have price setting power, so the industries have competitiveness on greenhouse gas mitigation policies.

This study analyzes the decision-making processes for university students to choose the location of their future houses in metropolitan area. Based on their intuitive judgment, the university students prefer the general criteria, transportation, facility, education and society, and economy in order. The Kendall coefficient of concordance W which determines the association among the rankings of the students' judgement on the importance of the general criteria is so low. It means that the students highly disagree their rankings of the importance of the general criteria. The rankings of the importance of the criteria like as transportation and education society are concentrated on a mean value, but those of the criteria like natural environment and economy are relatively dispersed. The students prefer the area between the center of Taegu-si center and its outskirts, the outskirts of Taegu-si, and the center of Taegu'si in order as an alternative location of their future house. From the specific criteria like the price of land and house, the student's preferences on the alternative locations of future house are varied as compared with those of the general criteria. According to a sensitivity analysis, the student's preference on the center of Taegu-si is increased, but that on the the outskirts of Taegu-si is decreased as the importance of facility and transportation factor is increased. On the contrary, the student's preference on the outskirts of Taegu-si is increased, but that on the center of Taegu-si is decreased as the importance of natural environments is increased.

The socio-economic and environmental systems of world are in turmoil. International conflicts are placed in their geographical context through the integration of maps. Changes in the world political map have often been the outcome of wars and conflicts associated with major geopolitical transitions. We identify five basic types--proto-nationalism, unification nationalism, separation nationalism, liberation nationalism and renewal nationalism. Political leaders in a wide range of contexts have been able to appeal to the nationalist doctrine to justify their actions. In recent years indigenous peoples have found a new voice in their struggle for survival. Although colonial empire's ending followed long and bloody struggles in some places. We really cannot understand the modem world as a whole if we do not understand the dynamic of that part of it which has endured and struggled against colonialism. The patterns of the international conflicting area are divided internal conflict type, mixed conflict type, international conflict type. The formation factors of the international conflicting area are divided ethnic group, religion, colonialism, resource, territory. There has recently been a resurgence of Islam's importance in world affairs. The oil crises of the 1970s gave new international leverage to several Muslim states.

This paper is to analyze citizens' consciousness on urban changes, especially focusing on changes in urban environment, spatial structure, and urban planning, of large cities in S. Korea, that is, Seoul, Daejeon, Daegu, and Kwangju in the 1990s. Some significant points can be described as follows. First. The most important factor influencing on the change of urban spatial structure was the expansion of residential area inner and outside of cities promoted by the traditional construction industry, and not development of high-tech industries and their complex or location of multi-national firms which can be emphasized as major factors of new urbanization process of global cities. Secondly, citizens seem to have experienced improvement and deterioration of urban environment simultaneously, emphasizing regulatory environmental policy on the one hand, and recognize the necessity of sustainable urban development within given environmental capacity and restoration of destructed and polluted environment of cities. Thirdly, the building boom of new apartment complex was a major driving force of changing urban spatial structure, but it could neither alleviate a residential gap between the poor and the rich areas nor a relief of traffic congestion. Finally, the urban policy in general was felt somewhat improved by citizens, but not in sectoral details.

Estuary of River Nakdong(in south-eastern coast of Korean Peninsula) is the most representative site of delta in Korea. This study is to elucidate morpho-structural background associated with the embayment area and sedimentation processes, having allowed development of the delta. In this area, Great morphological trait of the embayment area had been formulated by differential erosion exploiting regional fracture system(NNE-SSW, NNW-SSE, E-W,...) of tectonic origin. For this reason, outline of the embayment basin shows quadrangular plan, and ridges and dissected valleys of neighbouring mountains draw frequently morphological lineament pattern. At the last glacial age when delta deposit had not yet filled the actual embayment basin of the Nakdong, mechanical weathering(frost shattering) and mass-movement processes had provided detritus materials composed of blocks, boulders on bottom the basin. With the postglacial transgression in the Holocene, the basin had been submerged, then began to be filled with fluvio-marine deposits from Kimhae-Yangsan area toward actual estuarine zone, so that Nakdong delta have been formed. Analysis and synthesis of from hundreds of boring data of the delta area reveal that progression of delta formation have been accompanied with the development of barrier islands. If the barrier islands had grown as forming a plural row, then their intervals have posteriorly filled with another fluvio-marine deposits. Besides, it shows that delta deposits are essentially alluvial. However, at the periphery of the delta, intervention of fine marine deposits is frequently found.

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.

This study is aimed to examine the variability of consecutive dry days in South Korea. The country is divided into six basins including Han river, Nakdong river, Geum river. Seomjin Yeongsan river, Eastern Coast area and Island area, and three extreme precipitation indices-related to dry days are analyzed at sixty weather stations. Trends of max number of consecutive dry days were unstable during 1973~2010. Variability range of max number of consecutive dry days trends in Nakdong and Seomjin Yeongsan river was larger than that in Han and Geum river. Recently, the range in Nakdong and Seomjin Yeongsan river was bigger and bigger. Maximum dry spell was observed in autumn and winter in most of riverbasins. Especially, Maximum dry spell in winter was more frequent than in other seasons in Nakdong river. Variability range of persistence dry spells was smaller than that of max number of consecutive dry days. However, the increasing trends of the Geum river and the Seomjin Yeongsan river are statistically significant in recent. In Nakdong river, difference between persistence dry spell average and persistence dry spell median was larger than any other riverbasin. It means that there is strong possibility of occurrence of long term consecutive dry days in Nakdong river.

The rainfall partitioning in a monogenetic volcano has been analysed using the hydrological data of a small catchment on Eoseungsaeng-oreum of Mount Halla and the meterological data of Eorimok Automated Weather System. The experimental catchment extends from 965 m to 1,169 m in altitude, and has an catchment area of $51,000\;m^2$ Eoseungsaeng-oreum is the scoria cone predominantly covered with Carpinus laxiflora and Quercus serrata. The analyzed periods are April 30 to September 12 and October 7 to November 19, 2007. The experimental catchment exhibits the total precipitation of 2,296.5 mm. Surface runoff amounts to 465 mm that is equivalent to 20.2% of the precipitation. By contrast, evapotranspiration accounts for 25.9% of the precipitation, and the remnant of 1,236.5 mm deep1y percolates underground through a basement. The rainy summer season, in particular, shows the highest deep percolation ratio of 62.2%. The deep percolation ratio of the experimental catchment is at 1east more two times than the ratio of a gneiss basin in Korea Peninsular. It has suggested that the experimental catchment is characterized by the higher portion of deep percolation in rainfall partitioning which reflects the highly permeable lithology in Jeju Island.

Following the recommendations made by the cultural authorities the wooden cultural properties (WCP) had been treated with fire-retardants for fire protection. However, visual inspections of some of the WCPs treated with fire-retardants showed microbial decay. The work was extended to examine the micromorphological characteristics of the WCPs in a Buddhist temple which had been treated with fire-retardant. Microscopic examination showed the presence of typical soft rot cavities along the length of microfibrils in the secondary wall. Bacterial attack was also observed by scanning and transmission electron microscopy. It is interesting that the decay patterns observed in the Buddhist temple were very similar to those observed in the waterlogged woods. Presumably chemicals in the fire-retardants used rendered the wood susceptible to attack by soft-rot and bacterial decay by causing an increase in the moisture content of wood. Further studies are needed to investigate the effect of fire-retardants used currently on the hygroscopicity and the strength of wood materials in the WCPs. Microbial attacks caused degradation of the secondary cell walls and in some cases also of the middle lamella. In addition, the cell walls in the outer parts of wood were also degraded due to weathering, and cell separation occurred from total disintegration of the middle lamella.

This study tries to investigate the differences in combination of gold and other metals used in the surface guilt of the gold-guilt relics found in the Seonwonsa Temple of the Korea Dynasty. Our findings are as follows. The gilded roller knobs found in the Seonwonsa Temple of the Korea Dynasty can be classified into three groups by the color of the surface guilt: gold, white-gold, red-gold. By the color it is found that gold type contains $Au\;81.0\%,\;Ag\;3.5\%,\;Cu\;5.6\%$, white-gold type contains $Au\;82.1\%,\;Ag\;10.6\%,\;Cu\;2.4\%$, and the red-gold type contains $Au\;59.9\%,\;Ag\;3.7\%,\;Cu\;33.2\%$. The gold metal used for guilt is found to be amalgam of Hg and the depth of the guilt was uneven with the average of $2.5\~25{\mu}m$. These gilded roller knobs were produced in two methods. One of them was made out of pure bronze, and the other out of bronze veneer and led. Since we found led on the outer surface, we conclude that the led juncture was later guilt with gold.
