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.

한인 13가구가 최초로 러시아로 이주한 1863년 이후 그 수는 기하급수적으로 증가하였다. 초기에는 국경지대를 중심으로 한인촌을 형성하였으나 점차 연해주는 물론 동시베리아 지역으로까지 확산되었다. 블라디보스토크에서도 도시의 건설 및 성장과 함께 한인 집단 거주지가 형성되었고, 두 차례 에 걸친 강제 이주와 한 번의 자발적 이주로 위치가 이동하였다. (중략)

Marriage Immigrants have greater impact on local communities than migrant workers and foreign students, all the more because their children are relatively more important. Therefore, this study aims to inquire into the fundamental cause on the choice of residential location of marriage immigrants. Residential segregation is often considered to be one of the social problems that intensify locality of residential district. Although migrant workers and foreign students cannot freely decide their residential location at the outset, they could change their residence later on. However marriage immigrants are not free from the residential location choice continuously. The intentional(involuntary) residential segregation brings differential residence of marriage immigrants. The residential segregation of marriage immigrants is concerned with the close relationship of their ethnic background and the community characteristic with focus on Vietnamese and Filipino. The results of this study could be used basic guideline for community development policy for marriage immigrants.

This study aims to analyze the determinants of residential location choice for the inter-urban migrants in the Seoul metropolitan area. In doing so, we have built a discrete choice model, using household sample data from the 2010 Korea Population and Housing Census. We classified households, which made a intra-urban movement during the last five years, into four groups: 1) movers from Seoul (central city) to Gyunggi-Incheon (suburban), 2) movers from Gyunggi-Incheon to Seoul, 3) Intra-Seoul movers, and 4) intra-Gyunggi-Incheon movers. The analysis findings can be summarized as follows. First, significant differences in the determinants of residential location choice were found among different types of movers. Second, movers from Gyunggi- Incheon to Seoul were likely to choose small housings with fewer rooms, indicating that their housing choices were forced rather than voluntary due to high housing prices in Seoul. Third, all types of movers have a high preference for the neighborhood with a good accessibility by public transit including subway. Lastly, neighborhood amenity was also an important attracting factors for the intra-urban migrants in Seoul.

Multitasking has become part of our life. Self-interruption and switching to another task become easier and more frequent. According to previous studies, however, most of the task-switching incurs a cognitive cost. This study investigated the benefit from task switching. In Study 1, participants performed two tasks were similar, and negative correlation between the number of task switching and performance were confirmed, this result is similar to previous studies. Study 2 has shown that, made a comparison of two conditions, between possible and impossible conditions in terms of task switching. Depending on switching preference, the result of task performance has differentiated and the emotion that participants had before the task has changed. Depending on participants' switching preference, there were different amount of switching cost. Moreover, for participants who preferred task switching highly than others, task switching occurred more benefit than cost.

Delayed tooth eruption is the most commonly encountered deviation from normal eruption time. Racial, ethnic, sexual, and individual factors can influence eruption and are usually considered in determining the standards of normal eruption. Delayed tooth eruption was affect to the dentition and facial growth, so that when it occurred careful evaluation should be performed to establish the cause and the treatment plan accordingly. Present 3 cases of delayed tooth eruption by periapical lesion, underdevelopment of incisior and compound odontoma were successfully treated. In these cases, we could observe spontaneous eruption of the delayed erupting tooth after removal of interrupting factor and space regaining with maintaining.

The pulp infection of primary tooth is often caused by dental caries or trauma. But, if it is not managed properly, it can be produce the periapical lesion. The periapical lesion can cause some complications such as enamel hypoplasia, displacement, root dilaceration and impaction. Treatment options of displaced permanent successor are clinical and radiological follow-up after extraction of primary teeth, surgical opening, orthodontic traction, transplantation and extraction. In these cases, the premolars with abnormal eruption path caused by periapical lesion of the primary tooth have shown successful spontaneous eruption just as a result of extraction of infected primary tooth and space maintenance.

Dilaceration is most common in maxillary central incisor. Impaction by dilacerated tooth cause orthodontic problem such as tilting of adjacent tooth, midline deviation. Dilaceration is caused by trauma, cyst, other origin and tooth shape, degree of root curvature, location in the alveolar bone, ability of spontaneous eruption should be considered whether treat or not. Labially and lingually dilacerated tooth is difficult to spontaneous eruption. Thus, Prosthetic treatment alternative with extraction, auto transplantation, orthodontic traction with surgical exposure is included within the treatment alternative. These cases are about impacted central incisor with dilacerated root. We use closed eruption technique and guide impacted tooth into normal position by orthodontic traction.
