Vietnam's growth as the second largest coffee producer in the world has been fueled by domestic migration into central highlands. However, the detail migration processes have not been explicitly discussed. In particular, the existing literatures tend to describe the migration flow in a framework of planned migration versus spontaneous migration, paying less attention to the linkage between them. With a case study of Dak Lak province which is the leading robusta producer in Vietnam, this research investigates the linkage between planned and spontaneous migration in a multiscalar approach. The statistic data allow the researcher to know temporal association between the two type of migration in a provine scale. The survey and interview about two coffee-producing communes - Ea H'Ding in Cu M'gar district and Doan Ket in Krung Buk district - inform us that the linkage between planned and spontaneous migration is contingent to the local contexts including ethnic composition, timing of settlements, governement's development program, and timing of a large flow of in-migration.

China is pushing a policy called China's Western Development in order to balance the continent's development level. They are connecting the rich natural resources of the mid-western areas and the capital of the eastern coastal areas of China. Since Korea depends on China the most for trade, it is necessary for Korea to always consider the trade scale and pattern changes of China. Response to changes in the transport and logistics system between the two countries is also demanded. This study aims to analyze the import and export trends between Korean and Chinese provinces of each item from the trade scale point of view. China's global trade routes reorganization and China's western development are considered and the corresponding direction is presented accordingly. The study also suggests strategies to expand the import and export scale with China based on the analysis.

China has experienced rapid economic growth and burgeoning trade since it began economic reforms and an opening policy. With this the amount of marine cargoes between Korea and China had been increased Recently this increasing rate of cargoes, the development of the Yellow Sea Sub-Region and the change of the Northeast Asian logistics network have acted as important factors of Korea's strategy to be the Northeast Asian logistics hub. This paper analyzes China's inland transport network to offer basic understanding on transport and logistics network in China. Therefore, the outcomes of this paper could be used as basic materials to further transport and logistics cooperation between China and Korea and to developing a more realistic plan to complete Korea's Northeast Asia logistics hub strategy.

This article deals with some issues with respect to the Mahan pottery excavated from the tombs. Pedestal jars with cover, small round-bottom jars, cylindrical pottery etc. had appeared in the interaction with the northern region in the dimension of the southern Korean peninsula. Especially, these relics had an important role at the route connecting the midwest region, Chungcheong(忠淸) inland and Yeongnam(嶺南) region. By this stage, the iron culture was similar to each other in the southern Korean peninsula. In addition to the inland route, the coastal passage along the west coast seems to have been used. Such signs are found in cylindrical pottery and Pedestal jars with cover. It was probably a natural phenomenon that the most powerful forces of Mahan appeared at this crossroad of cultural exchange. The unique style of Mahan pottery such as double-rim pottery had been established since the third century. After the third century, Mahan pottery varied by region depending on the tomb style. The difference roughly matches with the variations of the tomb style. But at the region of Bungumyo(mounded tomb), specific pottery such double-rim pottery had been prevalent than in other regions. And a specific style had been used in a narrow range. The pottery spread to the neighboring regions in the course of interaction and were also used in ritual practices.

The southern coastal area of Korean peninsula maintains unique natural views, social environment and tourism infrastructure. Even though the coastal area has world-class tourism resources and a great potential for development, it was an outsider from the tourism development in Korea. The coast development has recently reemerged because of increased tourism demand in the Northeast Asia, however, increased interest for the outstanding marine tourism resources and the marine culture, improvement of accessibility to the coast Considering these characteristics, the southern coastal area will be grown to a marine resort-belt, which will serve as a marine tourism hub in the Northeast. In the long run, it can be developed for leisure residential space with environment-friendly well-being fashion, new growing area that continuously drives the local development and area for a mutual development between Yeongnam and Honam Region. To accomplish this vision, several strategic matters should be resolved. Mall strategic issues are as follows: the loosening related rules and regulations that limit the development, legislation of a special law for tourism promotion, supporting for investment in public service and strategic investment, establishment of a marine tourism route connecting China-Korea-Japan, formulating new planning for Hallyo-Haesang Marine Park, designation of special marine tourism development zone, and invitation of the World Expo 2012.

Wetland is the ecotone between aquatic ecosystem and land ecosystem, and is much valuable in terms of ecology and economic. The stream wetland among inland fresh wetlands occupies the largest area but has been recognized as only a channel not a habitat. The purposes of this paper are to consider the characteristics of natural wetlands formed in the tributary flowing into the downstream reach of Nakdong River and to find its optimal management policy. Natural wetlands in the middle-size streams (2nd${\sim}$3rd order) are large marshlands, and were formed at the places from the mainstream away, because natural wetlands were formed in the reach of longitudinal profiles during the last glacial and the post-glacial period meet in disharmony. In order to conserve these natural wetlands effectively, we should compile the inventories of wetlands and make precise distribution maps. And we should do 'reverse-reclamation' which means the alteration of some farmlands reclaimed from natural wetland into natural wetland ecosystem, and develop the place or the space for wildlife education and ecotourism.

In the recent years, the development of coastal zone has been advancing, and the chance of leisure activity has increased near the sea. However, the destruction of ozone layer has resulted in an increase in the amount of ultraviolet radiation reaching the earth surface. The human body is harmfully influenced as skin cancer and eye damage by ultraviolet radiation. Especially, the effect of ultraviolet radiation on beach is higher than that inland area due to the reflection from the sand. This study is expected to use basic data on the method of measuring ultraviolet reflections on east coast beaches using remote sensing.

The purpose of this paper is to find the determinants of Korean FDI(1996~2012) in China using the spatial autoregressive model and four regions of China is analyzed respectively. Most previous studies ignored spatial interdependence to analyze the determinants of Korean outward FDI in China. Empirical results of total Chinese area shows per RGDP and spatial effects are positive and significant variables. Results of region A reveal that per RGDP is positive and spatial effects are negative and significant. Results of region B shows that both per GDP and spatial effects are positive. All variables of region C are insignificant but those of region D are significant and positive. This means that Korean companies to invest in region D should consider spatial characteristics of surrounding areas of D.

This study selected optimal sites in Myeongsasimni located in west coast of Korea for stratigraphic research containing extreme climate event during quaternary period by spatio-temporal analyses of changes in sedimentary environment and land use employing 1918 topographic map, 2000 digital terrain map, 1976 and 2012 air photographies. The study area shows no significant changes in topographic characteristics that hilly areas with relatively large variations in elevation are distributed over north and south part of the study area, and sand dues are developed along the coast line. Moreover, flat low lying areas are located at the back side of the sand dues. The movement of surface run off and sediment loads shows two major trends of inland direction flow from back sides of sand dunes and outland direction flow from high terrains inland, and the two flows merge into the stream located in the center of the study area. Two sink with individual area of $0.2km^2$ are observed in Yongjeong-ri and Jaryong-ri which are located in south central part and south part of the study area, respectively. In addition, sea level change simulation reveals that $3.4km^2$ and $3.64km^2$ are inundated with 3 m of sea level rise in 1918 and 2000, respectively, and it would contribute to chase sea level change records preserved in stratigraphy. The inundated areas overlaps well with sink areas where it indicates the low lying areas located in south cental and south part of the study area are identical for sediment accumulation. The areas with minimal human impact on sediment records over last 100 years are $3.51km^2$ distributed over central and south part of the study area with the land use changes of mud and rice field in 1918 to rice field in 2012. The candidate sites of $0.15km^2$ in central part and $0.09km^2$ in south part are identified for preferable locations of geologic record of extreme climate events during quaternary period based on the overlay analysis of optimal sedimentary environment and land use changes.

In this study we analyzed the spatial and temporal distribution and preferred habitat type of the Kentish plover (Charadrius alexandrinus) based on the 3rd National Ecosystem Survey. Kentish plovers were observed in 97 maps out of a total 842 maps (11.8%) between 2006 and 2012, mainly along the western and southern coasts of Korea. They were also observed in the eastern coast of Korea, inland rivers (Han, Geum, Nakdong, Seomjin, and Yongsan River), the western and eastern coast of Jeju island, and Daecheong Island in the Yellow Sea. The observations were mainly made during the spring breeding season and migration seasons in spring and autumn. The occurrence of kentish plovers was positively influenced by the area of water and wetland according to the middle classification level of land cover type analysis and the area of coastal wetlands in the detailed classification level of land cover types. Most (90%) of the kentish plovers recorded maps had coastal wetlands. Kentish plovers were known to be susceptible to change of habitat. As the occurrence of kentish plovers could be associated with the habitat-change of coastal wetlands and it is possible to estimate the number of individuals, it is recommended that kentish plovers be used as a bioindicator species for the ecological assessment of ecosystem in intertidal zones.
