A practical methodology for the determination of derived intervention levels (DILs) on relocation following an accidental release of radionuclides was designed based on dose rate on the ground. The influence of DILs was investigated with respect to the change of parameter values, which are dependent on socio-environmental characteristics in distinction from temporary and permanent relocations. The DILs on relocation showed a distinct difference depending on effective removal half-life of radionuclides following a deposition, delay time in measurement and residential characteristics. In particular, the delay time. In measurement was an important factor in determination of DILs in the case of an assumption that dose rate on the ground declines in a power function, not in an exponential function. The DILs showed lower numerical values as longer effective half-life, longer delay time In measurement and longer exposure time.

This study aims to reveal that the changes in the population and housing consumption of foreigners, which are constantly undergoing structural changes, affect both the housing market of home and host country. The cause and the change of foreigners' housing market in Seoul were analyzed to be that the foreigners' continuous inflows occurred due to the 'fixed effect of rent' on the rental market, which is different from the domestic housing market. Korean-Chinese, who tend to be circular migration, make the current concentration of the housing market. Meanwhile, Korean-Chinese, who have experienced migration from Korea, emerged as major housing consumers, causing a real estate boom in Yanji City. Housing investment by Korean-Chinese is concentrated in the 'West' from Yanbian University, closely related to the city's urban planning that affects housing supply. This transnational housing consumption of immigrants connects the housing market of home and host country, in turn, causes the filtering process in the two countries simultaneously, which results the 'transnational housing filtering process'.

This paper examines two different reunification regimes and investigates the decision making problems on tax and income transfers in a political economy model. The first reunification regime is the South-Driven regime under which the majority of South Korea choose the tax rate, the amount of transfers and the size of migration. The second is the North-Participation regime under which there is no limit on migration and the majority of Unified Korea choose the tax rate and the amount of transfers. In both regimes, Northern residents' migration decisions are endogenous and those who decide not to migrate to the Southern region have an alternative to declare fiscal independence of income redistribution taking place within the North independently. This paper shows that there is no income redistribution in a politico-economic equilibrium under the South-Driven regime. Given that, those remaining in the Northern region decide to declare fiscal independence. On the other hand, the North-Participation regime delivers an equilibrium supporting income redistribution and no fiscal independence.

The objective of this study is to examine the studies of foreign workers in Korea at a level of meta-analysis focusing on their subjects and methodology. Over the last 15 years, studies of foreign workers have diversified subjects and refined methodology reflecting major characteristics of migration patterns including a rapid increase in number, large populations of illegal sojourners, a majority low-skilled young male workers from less developed countries, and an active role of migrant-support NGOs. Nevertheless, the studies have shown problems such as a higher ratio of macroscopic discussions, overemphasis on social problematic issues and a tendency towards descriptive analysis. Methodologically, they have also revealed an inactive use of empirical and quantitative data, lack of representativeness of sample and disregard of an importance of language in the study of foreigners. Based on the analysis, this study proposes strategies to enhance researches of foreign workers in Korea.

2012년 통계청 자료에 의하면 한국에 체류하는 외국인은 약 160만명이고, 그 중 방글라데시 노동자는 약 4.7%(한국고용정보원, EPS, 2012)라고 한다. 본 논문의 연구를 위하여 김해(100명), 마산(60명), 인천(40명)에 거주하고 있는 방글라데시 이주 노동자 약 200명에 대하여 설문조사를 실시하였다. 이 연구의 목적은 그들의 직업만족도와 삶의 만족도 사이에는 어떤 관련성이 있는지, 그들의 한국에서의 삶의 만족도를 높이기 위한 방안은 무엇인지에 대하여 알아보고자 하는 것이다. 연구 결과 직업 만족도의 ${\alpha}$ 값은 0.71, 삶의 만족도에 대한 ${\alpha}$ 값은 0.72 이었다. 직업만족도에 대한 설문은 Paul E. Spector(1985)가 고안한 것을 사용하였으며, 삶의 만족도에 대한 설문은 Thomas M. Krapu외 4인이 연구한 것을 사용하였다. 연구 결과 방글라데시 이주 노동자의 직업만족도와 삶의 만족도 사이에는 강한 관련성이 있으며, 그들이 느끼는 삶의 만족도는 매우 낮았다. 이를 높이기 위해서는 정부와 시민단체들의 적극적인 지원이 필요하다고 분석되었다.

The number of Goryeo-in immigrants has been increasing recently. National attention and active interactions are required for them to settle down with the identity of Koreans. The purpose of this study was to develop volunteer activity for Goryeo-in immigrants based on service design. The study was performed in G metropolitan city from October to November 2019. The participants were 33 Goryeo-in immigrants and 3 stakeholders. Data was collected through a survey and interviews of Goryeo-in immigrants and stakeholder interviews. In the field surveys and interviews, it was found out that the main problems faced by Goryeo-in immigrants were communication difficulties, maladjustment, job insecurity and smoking. The core issue was defined as 'How Goryeo-in immigrant women can improve their communicate ability in Korean'. In order to solve this problem we developed a program called 'Goryeo-in Han-gul ssugssug' for volunteer activities, and the program delivered through a storyboard and a role play. Using the service design process, a meaningful volunteer activity was designed considering lots of situation of Goryeo-in immigrants and nursing students in various ways. This study shows that the service design methodology is a useful way to reflect the needs of consumers and volunteers in developing volunteer work.

There are many researches considering mobile devices as resources in mobile grids. However, the mobile device has some limitations: wireless connection and battery capacity. So, the grid operations using mobile devices have lower reliability and efficiency than those in fixed grid environments. In this paper, we propose a job migration scheme using mobile devices to overcome these limitations. The proposed job migration scheme predicts failure condition during execution and takes checkpoints. Then, if the failure occurs on mobile device during execution, the executing job can be migrated to other mobile device by checkpoint information. To perform the proposed migration scheme, we establish a mobile device manager on a proxy server and a status manager on a mobile device. Connection, wireless signal strength and battery capacity of mobile devices are identified through two managers. The simulation results show improvement of efficiency and reliability during execution.

The diversity of urban landscapes is established by dynamic characteristics such as language, color, and their movement, which are the building environment, street patterns, and people. With the increase of foreign migrants in Korea, new guidelines are needed in terms of local community administration and land policy. Administrative, sociological, and geographical studies have been conducted on the steadily increasing number of foreign migrants since the 2000s, but it is difficult to establish for making safe and healthy communities through which different cultures and lifestyles of each country and ethnic group undergo some integration with the existing host society. There are limitations in identifying the lack of statistical data and the representation of a minority proportion of foreign residents. In order to analyze the core elements of the integrated strategy of the local community, the residential behavior and spatial characteristics of foreign migrants must first be identified.

The purpose of this study is to analyze how the satisfaction of Korea life and attitude on sending information is influenced by the information cognition rate of Korea before influx to Korea. The method used for this study was to survey migrant workers in Busan and Kyeongnam area. The results show a tendency towards a higher information cognition when the information was acquired through manpower supply agencies and media information. In addition, among the variables of information cognition, when 'socio-economical' factor was high, the satisfaction rate of Korea life tended to be higher. Also, when the 'workplace environment satisfaction' factor was high, attitude on sending information tended to be positive. Based on those results, this study presented measures for establishing information policies, such as provision of high quality information, diversification of information route which are necessary for migrant workers.

This study explored the essential meanings of experiences that married immigrant women living in rural communities have in their community participation process and analyzed the situations and types of their community participation in order to support immigration women's community participation and develop strategies for social welfare by type of community participation. For these purpose, we analyzed story outlines, meanings, types and situations of community participation among married immigrant women who had been over 5 years since their immigration. According to the results of this study, the meaning of married immigrant women's community participation was "Recognize myself as the pioneer of my life and participate in social activities continuously." In the results of analyzing the types of participation, the subjects were classified into 'self directed growth type,' 'self content type,' and 'social support expectation type.' The results of this study are expected to be helpful to understand the life of married immigrant women in rural areas not as 'individuals' otherized in a foreign country but as 'participants' of community that are encountered naturally in daily life, and to develop community level services suitable for such women.
