  • Genetic variation of the beet armyworm, Spodoptera exigua (Hubner), was analyzed by polymorphic allozymes. Field populations were subdivided by different hosts, geographical locations, and seasons. Estimated average heterozygosity ($0.443\pm$0.013) indicated high genetic variation in all field populations of S. exigua. There were significant inbreeding effects deviated from Hardy-Weinberg equilibrium in each of subpopulations. These significant nonrandom matings were caused by within-subpopulations probably due to sampling errors, but not by mating isolation among subpopulations. Wrights ($F_{ST}$ ) and Neis (D) genetic distances indicated little genetic differentiation among subpopulations, though some southern local subpopulations (Haenam and Sachon) were relatively different of northern subpopulations (Andong and Kunwi). Estimated number of migrants per generation was 5.9 among host subpopulations, 10.6 among geographical subpopulations, and 31.8 among seasonal subpopulations. These genetic analyses suggest that Korean S. exigua subpopulations have little genetic differentiation mostly due to their significant migratory capacity.

  • The discipline of Geography is broadly concerned with the interconnections between people and the environment. Particularly, this unique human-environment relationship often can be typically reflected from, and well illustrated by, the dynamics of microstates' island environment. While Tuvaluans living on vulnerable, low-lying atolls in the Pacific are not primarily responsible for contributing to climate change, yet they are experiencing its dreadful effects. Population pressure, caused by the differences in population size, distribution, and composition, has been constantly affected by resource unavailability and environmental instability on the islands. It also represents one of our challenges in understanding the complex influence of population dynamics on the living environment. What can be learned from Tuvalu in the context of population geography and environmental geography as well as its relationship with other Pacific island microstates? What are Tuvaluans' migration responses to their atolls' environmental crisis as well as the carrying capacity scenarios related to overpopulation? What are the current living experiences and settlement situations of Tuvaluan internal and external migrants both at home and abroad? This research examines the contemporary migration literature in the context of Tuvalu's population geography, while analyzing Tuvaluan migration patterns, discourses and perspectives in relation to environmental change.

  • This study was conducted to study the effect of acculturation on the permanent resident and naturalized citizens' mental health status. The Survey Data of Foreign Residents in Korea 2012 was utilized. Independent variable was the acculturation level, measured by the duration of life spent in Korea and the level of Korean proficiency. The dependent variable was the mental health outcome. Initially, acculturation showed protective effect on mental health of immigrants. But after adjustment of control variables, the effect of acculturation disappeared. This result does not converge into the general trajectory of mental health status among immigrants regarding the level of acculturation. The experience of discrimination had outstanding negative effect, which suggests policy inception point.

A Study on the Regional Labor Migration in Experienced Employees' Sector: based on the yearly statistics of employment insurance 2008-2011 (경력직 노동력의 지역 간 이동에 관한 연구: 2008-2011년 고용보험통계를 중심으로)

  • This study is the analysis on the labor migration between 16 provinces in experienced employees' sector by using the employment insurance statistics of 2008 to 2011. In wage workers of Korea, all of regular and some of temporary employees subscribe to the employment insurance and among these, about 40-50% career workers have moved their jobs every year. Targeting these, first I perform cluster analysis to explore the spatial boundaries of intra and inter-regional labor migration, and second measure the regional linkages extracting the inter-regional migrants. As results, the clusters of labor migration are similar to 5+2 Mega-regional Economic Zones. However, in the regional linkages between clusters, Seoul-metropolitan area has a great influence to other regions in inflow and outflow.

  • Starch gel electrophoresis was used to estimate genetic diversity and population structure of Pyrola fauriena H. Andr. in Korea. The percentage of polymorphic loci within enzymes was $57.1\%$. The values of genetic diversity at the species level and at the population were higher than average values for herbaceous with similar life history traits (Hes : 0.149; Hep = 0.134, respectively), whereas the extent of the population divergence was relatively low $(G_{ST}=0.082)$. $F_{IS}$, a measure of the deviation from random mating within the 12 populations, was 0.298. An indirect estimate of the number of migrants per, generation (Nm = 2.81) indicates that gene flow is moderate among Korean populations of the species. Analysis of fixation indices revealed a substantial heterozygosity deficiency in some populations and at some loci. This indicates that some populations sampled may have been substructured largely due to rhizotamous spread and decrease of population sizes.

  • New urbanization different from the manufacturing based urban growth has been widely discussed in post-modern city, consumption city and others to reflect the urban changes in qualitative manner. Urbanization stage models consider large cities to be in mature stage, reurbanization and the stages are assumed to be experienced successively in lower sized cities. However, since the industrial restructuring implies new urbanization experiences, this study examines new urbanization in diverse aspects such as the population change and the geographic and social characteristics of commuters and migrants for the 6 large cities in Korea. Seoul follows the urbanization stages in order while other 5 large cities are divergent in their transition from the industrial city. Regional large cities reveal broad reverse commuting and selective in-migration of economically active households for better work and housing opportunities available in central cities. Similar to the consumption city thesis with enhanced cultural and recreational amenities in western cities, the widening urban residential function including housing and other services is a new urbanization characteristic of large cities in Korea.

  • This Research is to study types and distribution for place name of migration derived from Korea Peninsula by analyzing villages name of the Yanbian Korean Autonomous Prefecture. Village names of Yanbian Korean were identified as 945 out of 2,015. Place name migrated from Korea Peninsula was turned out 51 villages. Up to the present time in the Transition of China, 34 place names were disappeared, maintained place names were 16, and rehabilitated place name after loss was 1. The place name by naming method were classified as small area directed migration, large area directed migration, and merged migration. In case of small area directed migration, origin and destination is same such as Jeongeup and Muju, Cheonbuk, large area directed migration is named case by region migrants like a Gangwonchon named by people moved from GanwonDo, and merged case combine initials with each village names in case of GilseongChon by colligated Gilju and Seokseongmyeon. The results will be expected to support research information for identity and ethnical migration process.

  • As more migrants stay for a longer term or settle in Korea through marriage, labor contract, defeat of North Korea, etc, the discourse on the migration policies gets more complicated and expands further beyond the issue of their adaptation to the Korean culture and their rights to encompass their families and children. The social integration policies for children of migrant families in Korea have been mainly led by the Ministry of Gender Equality and Family and Ministry of Education, Science and Technology. This paper will look at the challenges that children with migrant background face and their problems while reviewing the policies on children with migrant background in a critical perspective. In conclusion, it gives some suggestions to help establish more open society with multi-cultural values espoused.
