This study examines migrant workers' occupational health and safety issues through a case study of the UK construction industry, focusing on structural vulnerabilities. Migrant workers are at the bottom of the hierarchically fragmented labour market, performing outsourced hazardous work. Structural vulnerability focuses on the social structures that create hierarchies and increase risk in the workplace, rather than on individual responsibility or 'cultural' differences of migrant workers. The study considers the structural factors that perpetuate the migrantisation of risk in the UK construction industry, focusing on the structural necessity of low-wage migrant labour, precarious employment and the legal status of migrant workers, and discusses how these three factors interact to increase migrant workers' vulnerability to health and safety. The migrantisation of risk is not only a matter of occupational health and safety or universal workers' compensation, but also of the intertwining of labour migration policies with employment structures that rely on low-wage, low-skilled labour. This calls for proactive measures to address structural risks that go beyond passive declaratory policies that do not exclude migrant workers from education, training or legal systems.

본문은 동북 3성의 지리, 역사, 연구 상황을 개술하고 착중하여 조선족이 동북 3성에 이주한 시기를 4개기로 나누어 그 분포 특징을 밝혔다. 4개의 시기는 (1) 함풍-동치년 시기 (2) 광서년 시기 (3) 선통-민국년 (4) 위만 시기이다. 매시기마다 조선족이 동북 3성에 이주한 역사 지리적 배경을 천명했고 당시 조선족의 이주 노선과 분포특징을 귀납하였다. (1) 조선족이 동북에 이주하여 온 노선은 모두 20개 노선이 있었다. 그중 이주 수량이 많은 노선으로는 종성-개산툰-용정 노선, 남양-도문 노선, 만포-집안 노선이다. (2) 압록강 유역의 중간진에서 중국 림강에 들어온 이주민이 가장 일찍 했다면 두만강 유역은 10-20년 더 높다. (3) 동북 3성 조선족 인구밀도는 두만강과 압록강에 가까울수록 크고, 멀수록 작다. (4) 압록강, 두만강 유역에는 평안도와 함경도의 이주민이 많고, 두 유역에서 북쪽으로 갈수록 조선 남부의 이주민이 많다. (5) 동복 3성 조선족은 산지보다 평원에 많이 분포되었는데 동북의 수전개발에 커다란 공헌이 있다. (6) 중국 조선족에 97.1%가 동북에 집중되나, 그중에서도 길림성에 1,811,946명으로서 전국 조선족 총수의 65.8%를 차지하고, 흑룡강성에 452,398명으로서 25.2%를 차지하며, 요넝성은 230,378명으로서 9.0%를 차지하고 있다.(1990년 통계) (7) 도시에 있는 조선족은 모두가 잡거하고 농촌에서는 잡거구도 있지만 대부분은 순 조선족 부락을 이루었다.

In this paper, we propose a migration technique for autonomous mobile agents suitable to dynamic environments. The proposed migration technique dynamically creates the itinerary of agents that considers states of networks and systems. In the migration of the agent, it first sends prefetching message to the next system. The system receives necessary data for migration in advance. Through this, we reduce the amount of the sending data and save the time for creating the instance of the agent. And it improves the execution efficiency by using the checkpoint-based recovery method that does not execute the agent again and recovers the process states even though the errors take place. To show superiority of the proposed technique, we compare the proposed method with the existing methods through various simulations.

The purpose of this study is to capture how marriage migrant women, who are burdened with the luggage of the social, cultural, and historical 'past,' reconstruct their own 'experiences in reality' as subjective agents after their immigration into a new space. By applying a phenomenological method, this study analyzes the world of life in which marriage migrant women come to have experiences in the dimensions of bodilihood, spatiality, temporality, and relatedness. As a result of the analysis, marriage migrant women never think of their bodiliness as the subject of discrimination though they have some differences in skin colors and cultural aspects, and make efforts to overcome prejudices in reality withtheir pride of body. As for the spatiality, marriage migrant women attempts at a spatial turn in which they reconstruct a novel sociocultural space. With respect to the temporality, marriage migrant women recognize themselves not as passive subjects who only resent reality but as being prepared for future actively. As for the relatedness, marriage migrant women show life in which they pioneer their own areas on the basis of extended personal relations.

The mobile agent, which handles a given task while migrating between the sensor nodes, moves including the execution commands and task processing results. This increases the size of the mobile agent, causing the network to load, leading to the migration time delay and the loss of migration reliability. This paper presents the method of lightening the mobile agent using distributed object technology and the algorithm for exploring and providing the optimal migration path that is actively performed in the event of network traffic, and it proposes a method to ensure the reliability of the mobile agent migration by applying them. In addition, through the comparative analysis experiments based on agent size and network traffic for the migration time of mobile agent equipped with active rules in sensor network-based mobile agent middleware environment, applying the proposed methods proves to ensure the autonomy and migration reliability of the mobile agent.

As foreign immigrants are rapidly increasing, how they without previous knowledge and experience adjust themselves to local circumstances where they come to live becomes a major social issue. In order to analyze their adjustment process, this paper suggests a model which consists of relationships with local environment and people on the one hand, and of geographical knowledge and imagination on the other. The analysis of questionnaire survey based on the conceptual model suggests some findings. As there are considerable differences in the extent of their local adjustment and felt difficulties among immigration types, nationalities, and dwelling regions, foreign immigrants‘ policies should be devised proper for their type and characters.

This paper describes the efficient peer-to-peer migration method of Grid service agent on the mobile agent based P-Grid. The migration mechanism for transmitting service agent upon the service request is based on the peer's logic network topology. The network topologies that this system uses are organized as star topology, ring topology and tree topology, and agents are migrated by the master/slave method and serial/parallel method. The migration method of services is chosen based on the execution range and characteristic of the requested service. Also, the entire execution time of service is affected by the performance of peer that is a part of network topology, and the migration order, Therefore, the system monitors the performance of peers, and determines the migration priority based on analyzing and learning history. The system can reduce service execution time efficiently with decisions of migration method for service agent and priority of peers.

This study examines scale issues in the contemporary feminist migration literature. Scale appears as important, yet poorly understood concept in this field of study. The increasing attention to the feminization of migration requires not only gendered, but also scalar-sensitive approaches. Feminists criticize the conventional approach to the migration as a gender-blind approach that privileges national scale around which migration processes are organized. Claiming multiscalar and interscalar analyses, they propose investigations ranging from macro to micro processes which include globalized gendered division of labor, transnational family networks, and reproduction which takes place in and through the bodies and homes of migrant women. The migrant women, the major actors in recent transnational migration, cross various borders: the national boundaries and the public and private divides, in particular. This crossover can unsettle patriarchal gender relations which have been established based on the physical and symbolic division of nation-states and public/private spheres. Blurring these divisions accompanies social construction of various scales. The transnational family networks of migrant women, for example, show the construction of a transnational scale by migrant women as well as globalization from below. This paper points out misunderstandings of scale in the feminist migration literature and attempts to fill the gaps by introducing the meanings and implications of scales developed mostly by feminist geographers. In so doing, it promotes the interdisciplinary communication.

연구의 목적은 최서해, 박계주, 안수길의 이민소설을 중심으로 1930년대 북간도에 대한 조선이민의 공간이미지를 조사하며, 이것이 이주와 정착과정에 미친 영향을 밝히는 것이다. 최서해, 박계주, 안수길은 리얼리즘 작가로서 많은 장편과 단편 소설을 통해서 당시 북간도라는 이민공간에 있었던 조서이민의 삶을 사실적으로 형상화하였다. 따라서 이들 소설은 그 자체로서 1930년대 북간도의 지리적 현상이며 동시에, 지리적 자료로서 가치를 지닌다. 조선 이민의 공간이미지를 보면, 이주 전 이미지와 이주 후 이미지 사이에 차이가 있다. 이주 전 이미지는 북간도 공간에 대한 지식과 그들이 접한 정보를 중심으로 형성된 객관적 이미지이다. 이것은 이주 후 삶의 공간으로서의 개인적 체험과 고향의식을 통해서 개별적이고 주관적인 이미지로 변화되었다. 객관적 이미지는 이주 의사 결정에 영향을 주었고, 주관적 이미지는 북간도에서의 적응과 정착과정에 영향을 주었다.
