This research examines individual attitudes toward immigration and the determinants of these attitudes in Korea, Taiwan, and Japan. Using 2003 National Identity module from ISSP data, descriptive statistics showed that Taiwan seems to be the most opposed to immigration, Japan in the middle, and Korea the least opposed. Despite being the least opposed to immigration, Koreans agreed most strongly with having a homogeneous sense of ethnic identity. In addition, Korean respondents saw immigrants are being good for the national economy, but not for cultural diversity. Binary logistic regression analysis showed that age is negatively associated with the individual's attitude toward immigrants in Korea, Taiwan, and Japan. Effects of educational attainment is only significant in Taiwan. Manual worker and others, and those who work in farming, mining, and fishing tend to have negative attitudes toward increases in number of immigrants. Also, individual's values toward immigrants/immigration are related to the individual's attitude toward increases in number of immigrants in Korea, Japan, and Taiwan.

Korea has experienced serious changes during the last several decades of industrialization. Limited land resources and excessive rural-to-urban migration inevitably resulted high-rise apartment housing development. However, apartment housing couldn't follow up social change and residents' needs. Turning into the 21st century, there are great demands for the diversification of housing style and amenity of housing, which include enhancing community lift through proper collective environment. To solve these problems, cohousing has been introduced in Scandinavian countries. A primary goal of cohousing is the desire of residents to live in a socially supportive setting. People can do housework together and also can promote active mutual relationship among residents in the community. Physical feature of cohousing, in combination with social organization factors, may serve to enhance or support the sense of community sought by residents. In this point of view, the purpose of this study is to find out the physical feature of cohousing in Denmark and Sweden. First, it is to figure out the background and development of cohousing in Denmark and Sweden. Then, by making clear physical features between similarity and difference of two countries of cohousing through case study; such as housing type, the circulation patterns, common facilities and etc. This paper could suggest a possibility of application of cohousing in Korea to present how they encourage emphasize design aspects that increase the possibilities for social contacts and the sense of community. Also, it goes on to suggest that the educational program and the support from the government.

Aim: To report epidemiologic and anatomoclinical transitions of inflammatory breast cancer (IBC) in Tunisia. Materials and Methods: Data including clinico-pathological data for 208 cases of T4d or PEV 3 non-metastatic breast cancer diagnosed between 2005 and 2010 were collected from patient records. Chi2 and Z tests were used to compare variables with two Tunisian historical series and a series about Arab-American patients. Results: Thirty three percent of our patients had their first child before 23 years of age and 56% had their menarche before 12 years, 75% never receiving oral contraception. Obesity was observed in 42% of women and IBC occurred during pregnancy in 13% of cases. Tumor grade was II-III in 90% of cases, HR was negative in 52%, HER2 was over expressed in 31% and invasion of more than 3 axillary nodes occurred in 18% of patients. We observed a pCR rate of 19% after neoadjuvant treatment (anthracyline-taxane used in 79%, trastuzumab in 27% ). Compared to historical Tunisian series (since 1996), IBC epidemiology remained stable in terms of median age, menopausal status and obesity. However we observed a significant decrease in median clinical tumor size and number of positive axillary lymph nodes. Comparison to IBC in Arab-Americans showed a significant difference in terms of median age, menopausal status, positivity of hormonal receptors and educational level. Conclusions: Our assessment of epidemiologic transition showed a reduction of clinco-pathological stage of IBC, keeping the same characteristics as compared to Tunisian historical series over a period of 14 years. Features seem to be different in Arab-American patients, probably related to migration, "occidentalization" of life style and improvement in socio-economic level.

In a first-of-its-kind study, terrestrial radionuclide concentrations were measured in 35 topsoil samples from the outskirts of Dhaka using HPGe gamma-ray spectrometry to assess the radiological consequences of such a vast number of brick kilns on the plant workers, general as well as dwelling environment. The range of activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K is found at 19 ± 3.04 to 38 ± 4.94, 39 ± 5.85 to 57 ± 7.41, and (430 ± 51.60 to 570 ± 68.40) Bq/kg, respectively. ²³²Th and ⁴⁰K concentrations were higher than the global averages. Bottom ash deposition in lowlands, fly ash buildup in soils, and the fallout of micro-particles are all probable causes of the elevated radioactivity levels. ¹³⁷Cs was found in the sample, which indicates the migration of ¹³⁷Cs from nuclear accidents or nuclear fallout, or the contamination of feed coal. Although the effective dose received by the general public was below the recommended dose limit but, most estimates of hazard parameters surpass their respective population weighted global averages, indicating that brick kiln workers and nearby residents are not safe due to prolonged exposures to terrestrial radiation. In addition, the soil around sampling sites is found to be unsuitable for agricultural purposes.

In order to examine differential mortality, the life tables for the insured persons in national pension scheme were estimated by sex and types of coverage(the insured in workplaces vs. the insured in rural areas). The averages of 1994-1996 data are used for insured in workplaces, but 1996 data are used for insured in rural areas. Life expectancies at the age of 18 are 59.5 years and 67.2 years each for insured males and females and thus 7.7 years longer for females than males in workplaces. Sex difference in mortality reduces as age increases, and more rapidly at younger ages than old ages. For insured in rural areas, life expectancies at the age of 18 are 51.4 years and 61.1 years each for insured males and females and thus sex difference is 9.7 years. The greater sex difference in mortality in rural areas can be explained by sex selective migration. The difference of life expectancy between insured in workplaces and insured in rural areas is 8.1 years for males, and 6.1 years for females. Because rural-urban difference in educational attainment is greater for males than females, the greater difference in life expectancy is observed for males than females.

This study attempts to explore the relationships of Korean Immigrants with New Zealand agricultural environment, their choice of agricultural occupations and adjustments. New Zealand, based on agricultural products in its economy, was one of the richest countries during the 1950s and 1960s because of its dependency in market to United Kingdom Since 1971 when U.K joined the European Community, its economy was no more strong enough to support the living conditions in the 1950's and 1960's. Therefore, New Zealand Government initiated some programme to assist its farmers. Such supports resulted in severe financial problems of the country. Thus, reforms removing almost all support programmes has been proceeded after 1984. Though horticulture is still lower in New Zealand's exports of agricultural products, its growth has been remarkable. This was results due to the contribution of smallholdings, along with migration from city to urban fringe occurred during the 1970's and 1980's. In the 1900's it has been known that horticulture in the smallholding takes a hard works for old ages, who required further partitions their lands. Meanwhile, the rapid growth of Korean immigrants to New Zealand in the 1900's has been occurred, and this study shows one or two years periods in the search of job in case of Korean farmers. The most attractiveness in agriculture for them was that it provides simultaneously both jobs and housing. Korean farmers' land use succeeds previous owner's land use, and concentrates on green house agriculture cultivating mainly tomato and cucumber. The size of land is quite small and not comparable to New Zealand's average size, but a satisfactory levels are rather high and successful in evaluating themselves concerning current occupations, even though they have rarely experienced about agriculture before. Korean farmers attributes a high satisfaction to agricultural techniques learned from previous owners and a related support authority. The results of this study showed that Korean farmers has been absorbed into New Zealand economy rather than Korean economy. Finally, it has been pointed that the growth of Korean farmers and agriculture in New Zealand is the results of complex factors such as occupations, children's educational opportunity, and the access to the city.

The purpose of this study is to find out about the cause and adaptation process of urban households going to rural areas for agricultural management(Kwihyang nongga) through the microscopic analysis of a case study. Research results are summarized in the followings. The cause of Kwihyang nongga before the 1980s was generally due to the social causes like the support of dependent family or rural-to-urban migrants' maladjustment in urban society. After the 1980s, however, it was related to the economic reasons such as the increase of households' income by commercial agriculture more than the social ones. Most of Kwihyang nongga was traditionally the households which came back to their native places, rural areas. Recently the urban households which did not originally come from rural areas are going to rural space because of the cultivation of high profit oriented agricultural products. Recent Kwihyang nongga increased the size of commercial agriculture through leased farmland, not by a purchase of agricultural land. Even though the number of Kwihyang nongga is now a few, it is expected that the influence of Kwihyang nongga on rural society will be various and high because it consists of young generation. The increase of Kwihyang nongga may be one of the ways to mitigate the decreasing rate of utilization of agricultural lands due to the labor shortage of rural areas after industrialization. To solve rural problems related to underpopulation, it is necessary to establish the active plicies of helping Kwihyang nongga. The actions for Kwihyang nongga ought to emphasize the improvement of educational conditions and living facilities as well as financial aids and the improvement of farming conditions.

Precise, rapid and simple methods for species identification in animals are among the most important techniques in the livestock industry and research fields including meat classification. In this study, polymerase chain reaction (PCR) based molecular identification using inter species polymorphisms were examined by PCR-restriction fragment length polymorphism (RFLP) analysis for mitochondrial DNA (mtDNA) cytochrome b (CYTB) gene sequences among four mammalian livestock animals (cattle, horse, goat and pig). The results from PCR-RFLP analysis using the AluI restriction enzyme were also provided for the species-specific band patterns among CYTB gene sequences in these four species. The AluI-digestion for CYTB genes provided interesting migration patterns differentially displayed according to each species. Cattle and horse had one AluI-recognition site at different nucleotide positions and their AluI-digested fragments showed different band patterns on the gels. Pig had two AluI-recognition sites within the amplified CYTB sequences and produced three bands on the gels. Goat had no AluI-recognition site and was located at the same position as the uncut PCR product. The results showed the species-specific band patterns on a single gel among the four livestock animal species by AluI-RFLP. In addition, the results from blind tests for the meat samples collected from providers without any records showed the identical information on the species recorded by observing their phenotypes before slaughter. The application of this PCR-RFLP method can be useful and provide rapid, simple, and clear information regarding species identification for various tissue samples originating from tested livestock species.

This qualitative study explores how Mongolian migrant workers, with a marked tendency for family migration, plan and put into practice their child's education and attach meaning to it in relation to the social network they form during their stay in Korea. Specifically, it analyzes in particular ways the social network Mongolian migrant workers form affect their settlement in Korea, the process by which the social network affects their planning of their child's education, and how the education planning and its realization lead to the formation of new social networks. The results show that parents were divided between those who made a deliberate decision in sending their child to the Seoul Mongol School as a part of their plan and those who chose the school due to forced circumstances. While some parents preferred the Seoul Mongol School over regular Korean schools for their child's education and future, others sent their child to the Seoul Mongol School, regardless of their preference, because they did not have access to information about regular Korean schools, were afraid of divulging their illegal status, or were afraid their child would not be able to adjust to the school life in Korean schools. Based on such analysis, this paper stresses the urgency of further research in this area, and suggests direction for future policy measures.
