In order to investigate contamination of heavy metal in seawater and cultured oyster, samples were collected November 2003 to July 2004 from 12 sites (13 sites for seawater) along the coast of Tongyeong, Korea. The mean concentrations of metal in oyster tissues were as follows: 0.09 (0.01-0.3) ${\mu}g/l$ for Cd, 0.47 (0.01-1.4) ${\mu}g/l$ for Cr, 0.59 (0.2-2.3) ${\mu}g/l$ for Ni, 1.02 (0.1-4.2) ${\mu}g/l$ for Pb and 0.48 (0.01-3.9) ${\mu}g/l$ for Hg in the seawater, whereas 2.45 (0-5.47) mg/kgDW for Cd, 3.63 (0.10-12.91) mg/kgDW for Cr, 3.2 (0.01-15.73) mg/kgDW for Ni, 3.51 (0.01-6.47) mg/kgDW for Pb and 0.39 (0.004-0.74) mg/kgDW for Hg, respectively. Most metal concentration values were below the permissible range for the related regulations. Mean bioconcentration factors (BCF) for each metal were as follows: 38,964 (1,771-207, 171) for Cd, 9,583 (1,231-80, 162) for Cr, 191 (3-20, 980) for Ni, 1,416 (245-5, 207) for Pb and 180 (5-716) for Hg, respectively. The BCF values from this study corresponded to the transitional phase from the pristine to the contaminated waters. Notably, Cd showed the highest BCF, which suggest that the Pacific oyster could be utilized as a useful biomarker for Cd contamination in sea water. The multidimensional scaling analysis suggested that the metal contaminants are mainly originated from combustion of fossil fuel and accumulated to oyster through food web.

The purpose of this study is to investigate the factors that interrupt the use of social security of elderly North Korean refugees. As a result of qualitative content analysis using interview data, it is found that the elderly North Korean defectors have a lower access to the social security system. The main reason for hindering the use of social security system is low awareness due to limited information channels, psychological distance to South Korean society and residents. Moreover, this psychological distance is a factor that reduces the geographical accessibility of elderly North Korean defectors by preferring to use services in specific institutions for North Korean, while South Korean elderly people can use the service elsewhere. In addition, there are many cases in which the elderly in North Korean defectors do not receive sufficient social security due to low income. On the other hand, social security systems with high accessibility of older North Korean refugees are characterized by the fact that they are provided by experts who have formed sufficient rapport with North Korean refugees. Therefore, it seems possible to improve the accessibility of elderly defectors' friendly system by professional workers with cultural competence. In addition, a multidimensional approach is needed to fully cope with the complex desires of elderly North Korean defectors and a mechanism should be set up to reflect their opinion in system operation.

The present work aims to analyze the concept of space in $Jes{\acute{u}}s$ $Fern{\acute{a}}ndez$ Santos' work Los bravos. Throughout its pages, one can observe the multidimensional possibilities of space in literature. Throughout time, the concept of literary space has developed and it has been modified constantly in order to meet the needs required for the evolution of narratology. In the past, Aristotle stated that space is the place where characters and physical objects happen to exist. This remained almost unchanged until the Renaissance. In the $19^{th}$ century, space stopped being considered just a mere scene where the action takes place as it was given more importance by romantic authors in their works. Realism intensified the spaces as the interior of the house. In fact, the descriptions of space became more important. In this article, I focus on the various meanings of space in the novel Los bravos. First, I analyze the dichotomy between real and ideal spaces, and continue with the cathartic dimension of the fictional space. Then, I present and analyze the opposition between urban and rustic spaces in this novel, and, finally, I show the confrontation between the spaces of men and women. Through this analysis, we can observe that characters have a space where they feel more comfortable and how, occasionally, they leave their "usual space of action" to reach their "ideal place". Women want to stay in their kitchen to chat with each other, while men prefer to leave the house to visit a cafe with their colleagues. The door and the window divide the border of the worlds of men and women. However, that line is not only dividing the structure of the house, but it is also of a psychological house.

The purpose of this study is to identify the overall effect of Family Hope Partner Project conducted by the Korean Association for Children with Leukemia and Cancer (KACLC) for pediatric cancer patients and their families and provide empirical basic data for the support of them. For this purpose, this study applied a qualitative research methodology as follows; 6 parents and 5 children who used the service for more than one year through the Family Hope Partner Project participated in the interviews. The interviews were conducted from June to July 2016, and the collected data were analyzed through the processes of qualitative analysis. The results of this study are as follows. Pediatric cancer patients and their families who were previously confronted with problems such as a 'barrier of severe pain' and 'swirling anxiety and exhaustion' experienced multi-dimensional effects, thanks to the intervention of 'a genuine master serving as a stepping stone toward their recovery and growth', who were linked to the pediatric cancer patients through Family Hope Partner Project. In other words, they experienced positive effects such as 'support for overall rehabilitation of pediatric patients', 'improvement of family relations', 'relief of needs for social relations', and 'liberation from pressure'. The results of this study were meaningful, in that it substantially corroborated the multidimensional effects of the Family Hope Partner Project, and presented the development direction of the Family Hope Partner Project, which was the first of its kind at home and abroad initiated by the Korean Association for Children with Leukemia and Cancer (KACLC) for pediatric cancer patients and their families.

The purpose of this study was to examine how various dimensions of social exclusion experienced by married immigrant women are affected longitudinally. Autoregressive cross-lagged analysis between sub-dimensions of social exclusion of married immigrant women was conducted to investigate the direction of interrelationships. The data were collected each year through a three-wave longitudinal survey from 2011 to 2013. The results showed that statically significant autoregressive effects appeared among economic exclusion, community exclusion, educational exclusion, and ethnic exclusion. The cross-lagged effects of the sub-dimensions of social exclusion showed that married immigrant women with higher levels of the economic exclusion tend to experience higher levels of the educational exclusion, and ethnic exclusion at the later measurement point, even when controlling for their previous level of social exclusion. It was found that economic exclusion as a more fundamental precedent factor positively predicted other dimensions of social exclusion. The results suggested that financial support and job-related services should be strengthened for active social inclusion of married immigrant women, and early intervention to prevent chronicization of social exclusion should be needed.

This research aims to examine whether depression has mediating effects in the effects of socioeconomic deprivation, especially of lower variables of socioeconomic deprivation on life satisfaction of the elderly. For this purpose, the 12th year(2017) data of the Korea Welfare Panel Study were used. The mediated effect analysis method of Baron and Kenny(1986) were used, and mediating effect of depression was validated through Sobel Test. The results of this research are as follows. Firstly, the lower variables of socioeconomic deprivation of the elderly -deprivation of housing, deprivation of dietary life, social deprivation, deprivation of employment, and deprivation of healthcare- had partial mediating effects of depression in life satisfaction. It was verified that as the elderly experienced deprivation of housing, deprivation of dietary life, social deprivation, deprivation of employment and deprivation of healthcare, depression increased and life satisfaction was lowered. Therefore, it was suggested that to enhance the living satisfactions of the elderly, policies and services reflecting the personal characteristics of socioeconomic deprivation and depression must be made, and that criteria to identify the multidimensional poverty and deprivation experienced in everyday life must be prepared in addition to poverty focusing on income.

Dietary niches can support the coexistence of sympatric species in marine ecosystems, which can lead to the presence of greater abundances of those species. Stomach contents of silver croaker (Pennahia argentata) and Japanese sillago (Sillago japonica) inhabiting the Nakdong River estuary, Korea were analyzed to determine diet compositions and the presence of any size-related and inter-specific feeding relationships. These species were bottom-feeding predators that consumed mainly benthic crustaceans and mollusks, but polychaetes were also important in the S. japonica diets. Non-metric multidimensional scaling (nMDS) ordination and multivariate analyses based on weight contributions of the different prey taxa to stomach contents revealed significant inter-specific dietary differences. Size-related change was also significant for P. argentata diets, but not for S. japonica. Canonical analysis of principal coordinate (CAP) ordination plot further demonstrated that differences in the type and range of prey ingested by the two species contributed such an inter-specific difference in the diet compositions. The results from this study provide clear evidence of niche segregation between co-occurring P. argentata and S. japonica in the Nakdong River estuary, which would reduce the likelihood of inter-specific competition for food resources.

The purpose of this study is to analyze whether parents with developmental disabilities are well represented by the persons with developmental disabilities. Analysis data is based on the data from the Survey on Disability Survey in 2014. We analyzed the consistency and biases of the parent's proxy respondents' opinions by the degree of agreement between the contents of the person with developmental disabilities and the value of items that the parents answered on behalf of the development disabled. First, the parents' proxy respondents responded well to the actual situation such as life satisfaction for the developmental disabled, while the parental proxy respondents showed the positive bias to overestimate the cost items and the negative bias to recognize the discrimination. Second, in relation to independent living, the majority of the parents of the developmental disabled respondents had a high agreement with the developmental disabled person. However, about 5 ~ 10% of the parents' proxy respondents seem to have a tendency to distort the independent living policy by preferring non-standard housing types, unlike those with developmental disabilities. Based on this, it was proposed that the respondents should be able to receive the answers of the possible parties in the future research on desire and independent living related intention toward the developmental disabled, and the research on the matching of the proxy response is needed in a multidimensional manner.

Along with the well-established evidence on the negative effect of social isolation on physical and mental health, increasing attention has been paid to multi-dimensional nature of social isolation. One line of study on social isolation has discussed different pathways between objective and subjective social isolation and health. Another stream of the research focused on the possibly non-linear association between social isolation and health by age cohort groups. Drawing from the two lines of research, this study aimed at empirically examine to what extent objective and subjective social isolation are associated with physical and mental health independently and how the associations vary by three age cohorts(i.e. the middle-aged, the young old, the old-old). Data came from the first wave of Korean Social Life, Health and Aging Project (KSHAP) (N= 814). Findings showed 1) objective subjective isolation were significantly related with worse physical and mental health, interestingly, subjective social isolation was associated with mental health only, 2) pattern of association between social isolation and physical health varied by age cohorts. Specifically, compared to the middle-aged, the young old with higher objective social isolation exhibited lower level of physical health, while the old-old with higher subjective social isolation were likely to experience lower physical health. Based on the findings, we discussed implications and suggestions for future research and relevant policy/program development for ameliorating objective and subjective social isolation.
