  • This paper examines the level of community solidarity in an administrative district in Seoul, Korea. This paper focuses on the following questions: what is the level of community solidarity in the district? and what are the major predictors of community solidarity?. Using the data from the 2000 community survey about residents' needs conducted by the welfare administration office of the district, this paper attempts to answer the above research questions. In analyzing the effect of community solidarity, this paper focuses on the following four predictor categories: individual characteristics; community related characteristics such as degree of marginalization; community participation, and community problems. Results are as follows: (1) the average of community solidarity is 3.1, using 5 points scale; and (2) the variables such as marginalization and community problem have a negative effect on the level of community solidarity; and (3) community participation has a positive effect on the level of community solidarity. Through the empirical analysis. this paper provides valuable knowledge about the level of community solidarity and effects of community participation, marginalization, and community problem on community solidarity. Finally, this paper discusses implications for effective community practice on the basis of the exploratory findings about community solidarity in Korea.

  • The purpose of this study is to compare the aspects of acculturation and the acculturative strategies of Chinese, Vietnamese, Mongolian, Japanese international students in Korea and to explore the correlation between acculturative strategies and acculturation as well as between acculturative factors and acculturation. The analysis revealed (i) that all of the international students from four countries adapted well to Korean culture in order of contentment to the collegiate life, personal factors, Korean living culture, social factors, Korean classes. Further, (ii) frequently used acculturative strategies of Chinese, Mongolian students were in the order of separation, marginalization, and assimilation while the most often used acculturative ones of Vietnamese and Japanese students were in the order of marginalization, separation and assimilation. In addition, (ⅲ) the acculturation of international students from four countries showed a significant correlation with personal factors, Korean living culture, contentment to the collegiate life, and (iv) the acculturation of Chinese students showed a positive correlation with separation strategy. In contrast, there was a negative correlation between the marginalization strategy and the acculturation of Mongolian and Japanese students.

  • One of the most interesting points in the era of globalization and transnationalism is the movement of people, namely migration. This research aims to explain the discourse of marginalization on Korean-Chinese by Korean merchants as the migrants expand their shops in the Chinese Food Culture Street. The Chinese Food Culture Street has been formed by Korean-Chinese restaurants and shops for the process of differentiation from the Garibong-Daelim area. Korean merchants in the street are not opposed to the influx of Korean-Chinese into Korea, however they do not want to the influx of them into the Jayang area. As the influx of Korean-Chinese into this street has increased, so the Korean merchants in the street have marginalized them as dangerous element for local security, as immoral beings cling to their business, and as the main reason for the regional underdevelopment. However, this marginalization of Korean-Chinese makes difficult to understand the real change of local area, because there has been some positive effects by the influx of them such as the improvement of surrounding environment and the elevation of local imagination. This research clearly suggest that the marginalization of migrants by major society is from the fixed idea and prejudice, and this research suggest the need to further study on the occupation and change of local by migrants.

  • This study took the conceptual framework of acculturation styles into the empirical investigation of international students in Korea. This research identifies the differences in acculturation styles, the characteristics of each segment, the effect of acculturation styles on clothing involvement (clothing involvement and risk probability), and the effect of cultural orientation values (individualism and collectivism) as covariates. The participants were international students attending a university located in Seoul. Data from 153 international students were used for statistical analysis. Respondents were grouped into four acculturation styles (integration, assimilation, separation, and marginalization). The assimilation group had the highest mean score of clothing interest. Cultural orientation values showed a significant covariate effect. With individualism as covariates, the main effect of acculturation styles on clothing interest was significant. In clothing product evaluation criteria, the integration group regarded design, fit and trend as most important. The marginalization group showed a mean score that was significantly lower in brand preference and satisfaction; however, the assimilation group had a mean score that was significantly higher.

  • This research primarily aims at analyzing major crises originating from marginalizing population, especially in counties. In addition, based on the system dynamics approaches, it pays attention to divulging causal loop structure which has been rather strengthened by diverse interactions among key variables. Judging from simulation works, even though Korea is exposed to unprecedented aging trends over decades, its counter response seems inadequate and insufficient, mostly dismissing a series of impact embedded in the aging dynamics. This research statistically confirms that demographic marginalization trends have already begun in the villages within Eup and Myon counties. Furthermore, this research pinpoints out the fact that it would be almost impossible for majority of villages within Eup and Myon counties to escape from going out of existence in the course of time, as they tend to be entrapped vicious cycle of marginalization or extinction.

  • The Multigroup Ethnic Identity Measure(Phinney, 1992) was administered to 179 Korean-Chinese mothers and their 8th and 9th grade children in the Yanbian region of China. Children also completed the Depression, Self-Esteem, and Social Competence scales. Findings were that while there was no difference between mothers and their adolescent children in Integration and Marginalization, more Separation in mothers and more Assimilation in adolescents were found. Korean-Chinese adolescents who belonged to the Integration type showed higher self-esteem and social competence than those of the marginalized type. Children's self-esteem and social competence were highest when both mother and child were in the Integration type. These results support the notion that Integration reflects the most adaptive, while Marginalization is the most at-risk attitude to acculturation.

  • Distribution of farm produce in Korea is known to be inefficient due to the numerous stages that exist in the distribution channel. This has resulted in dissatisfaction for both farmer and consuers; farmers sell their produce at low prices to middlemen while consumers pay high prices for them because of price increases that occur in the distribution chain. We apply Spengler's theory of double marginalization to show that price increases are inevitable as the length of the farm distribution chain increases. We then show that the negative effects of double marginalization can be contained by setting up a physical distribution center. The physical distribution center effectively reduces the stages in the distribution from 5 or 6 stages to 3 or 4 stages. We also lay out the design and major characteristics of the distribution center, as well as the expected cost savings.

  • This article explores religious responses to significant cultural and social change in a northern Vietnamese delta village from 1996 to 2008-the second decade after de-collectivization. Drawing upon extensive fieldwork in both the village and surrounding religious networks, the article teases out the meanings of the new religious movements for northern rural people in the new era of market economy; the symbols, language, and metaphoric resources people used in response to their uncertainty and mistrust of the new social landscape; and the unintended consequences of rapid societal development such as marginalization, tensions, and social disintegration. The article argues that as in milleniarism elsewhere, new religious movements in northern rural Vietnam embody unorthodox syncretism between world religious and local traditions, thus linking past, present, and future. However, when drawing upon a common reservoir of memories and experiences to cope with risks and challenges of the new market world, local people not only drew on the power and imperial metaphor of deities in their traditional religion and belief, but became more creative to recuperate meanings, standards, and symbols from revolutionary discourse to reorient themselves, and overcome alienation and marginalization.

  • The objective of this study is to investigate the influence of husbands' sex role stereotype, intercultural sensitivity, and the acceptance of wife's culture on immigrant women's acculturation, marital satisfaction and life satisfaction in multi-cultural family in Korea. The data of 100 immigrant women and their husbands were analyzed. Husbands' mean age was 41.6 and wifes' mean age was 29.6. The results of this study are as follows. The first, husbands' sex role stereotype, intercultural sensitivity and the acceptance of wives' culture together explain only marginalization among wives' acculturation(integration, assimilation, segregation, and marginalization) significantly, but individual variable's effect was not significant. The second, husbands' acceptance of wives' culture explain marital and life satisfaction significantly. Third, only marginalization among four types of acculturation explain significantly marital and life satisfaction significantly. integration explain only life satisfaction significantly. Husbands' sex role stereotype is related with the acceptance of their wives' culture and their intercultural sensitivity negatively. In wives' acculturation, there is low positive correlation between assimilation and integration and moderate negative correlation between assimilation and marginalization. This study revealed that the marital and life satisfaction of immigrant women in intercultural family in Korea are explained by acculturation which was influenced by their husband's acceptance of wives' culture and they are not only immigrant wife's problem but multicultural problem.
