The aims of this study were to detect spontaneously occurring apoptosis in cultured porcine ovarian cells, to examine the role of growth hormone (GH), tyrosine kinase (TK), protein kinase G (PKG) and cyclin-dependent kinase (CDK) in the control of this process, and to determine whether the effect of GH on apoptosis is mediated by TK-, PKG- and cdc2-dependent intracellular mechanisms. We studied the action of pGH (10 ng/ml), blockers of TK (genistein, lavendustin, both 100 ng/ml), PKG (Rp-Br-PET-cGMPS, 50 nM; KT5823, 100 ng/ml) and CDK (olomoucine, $1{\mu}g/ml$), as well as combinations of GH with these blockers, on the onset of apoptosis in cultured granulosa cells isolated from antral (3-6 mm) porcine follicles. The functional characteristics of an early apoptotic event, DNA fragmentation, were determined using terminal deoxynucleotidyltransferase (TdT)-mediated dUTP nick end labelling (TUNEL), whilst morphological signs of advanced apoptosis such as pyknosis, chromatin marginalization, shrinkage and fragmentation of nucleus, were detected using routine light microscopy. After culture, some ovarian granulosa cells exhibited DNA fragmentation, which in some cases was associated with morphological apoptosis-related changes (pyknosis, shrinkage and fragmentation of the nucleus). GH significantly reduced the proportion of TUNEL-positive cells. Neither TK nor CDK blockers when given alone, significantly affected the percentage of TUNEL-positive cells although both PKG blockers significantly increased this index. Furthermore, TK and PKG blockers given together with GH, prevented or reversed the inhibitory effect of GH on apoptosis, whilst the CDK blocker olomoucine promoted it. These observations demonstrate apoptosis in porcine ovaries and suggest the involvement of GH, TK, PKG and CDK in the control of this process. They also suggest that the effect of GH on ovarian apoptosis is mediated or regulated by multiple signalling pathways including TK-, PKG- and CDK-dependent intracellular mechanisms.

The paper aims to identify how North Korean various economic agents respond to the economic crisis in North Korea, and how these multiple practices are entangled with its spatiality by through the questionnaire survey and in-depth interview targeted at North Korean refugees. The paper argues that it needs to examine the marketization in North Korea in terms of the domesticating recently debated in economic geography. In this perspective, the marketization in North Korea could be explained not as a grand project 'out there' with hegemonic power, but as various economic agents within their space are constantly (re)constructed through everyday life practices. Economic agents' responses to economic crisis, economic rupture, and economic marginalization could be identified in terms of articulation between economic and non-economic factors. More specifically, the paper emphasizes everyday life responses are over-determined by their economic and non-economic factors and its effectiveness is differentiated by their power relations.

This study is a basic research for the development of 'Marginal Village Policy' in response to the hollowing-out of rural areas. For this purpose, the viewpoint of "Regeneration" & "Reconstruction" of the "Marginal Village Theory" and the recent "Rural Planning Theory of Evacuation" in Japan were reviewed. The background and trends of Marginal Village policy in Japan were also investigated. And based on this, the implications and future tasks for Korea were summarized as follows; (1)It is necessary to be interested in the disappearance of villages and marginal villages and to form positive discussions and social consensus. (2)Continuous field investigation and management of changes in population and village functions at regional and village level are required. (3)In addition to increasing the importance of depopulation problems, it is necessary to establish 'marginal villages' as a public policy target. (4)It is necessary to review and consider the viewpoint of reconstruction along with regeneration. (5)It is necessary to pay attention that the software project is expanded, and the regeneration & reconstruction policies of the rural villages are aimed at revitalizing the rural community. (6)It is necessary to consider the possibility of applying 'spacial construction' along with the expansion of the academic debate on the 'rural planning theory of evacuation'. On the basis of this, in this study, rural villages were classified into 'continuous villages', 'semi-marginal villages' and 'marginal villages' according to the degree of marginalization, and the basic framework of 'Marginal Village Policy' was proposed, which is to encourage the differentiated policies of 'continuous villages' by 'rural village policy', 'semi-marginal villages' and 'marginal villages' by 'marginal village policy'.

This study examined the acculturation strategies of immigrant women and the relationship in adolescents' career development. The data were from 2016 Multicultural Adolescents Panel Study, 1,248 cases. The highest rate was the assimilation followed by integration, separation and marginalization among immigrant women' acculturation strategies. The parenting efficacy, behaviors for career development and parents' support were related with acculturation strategies. The adolescents' career attitudes and perceived career barriers were also related with the acculturation strategies of immigrant mothers. As compared other strategies, assimilation strategy had positive relationships with parenting efficacy, behaviors for career development, parents' support, adolescents' career attitudes and perceived career barriers. This study provided some implications for immigrant families with adolescents.

Purpose: The purpose of the study >was to examine the prevalence of work-related musculoskeletal disorders(WMSDs) and to identify the relationship between work-related psychosocial and acculturative factors and WMSDs among Korean-Chinese workers living in Korea. Methods: A cross-sectional survey was conducted with 195 Korean-Chinese workers who have worked full-time for the past 6 months. A structured questionnaire, including measures for musculoskeletal symptoms, physical demand, work-related psychosocial(job demand, job control, interpersonal conflict), acculturative (acculturation strategy and acculturative stress), and personal factors, was used. Descriptive statistics and logistic regression analysis were conducted using the SPSS WIN 17.0. Results: The prevalence of WMSDs was 64.1%. In comparison to Korean workers, job demand of this group was lower while both interpersonal conflict and lack of job control were higher among them. Integration was the most commonly used acculturation strategy and mean scores of acculturative stress were below the median. Acculturative stress was positively correlated with integration and assimilation while negatively correlated with separation and marginalization. Interpersonal conflict and integration appeared to be related to WMSDs among male and female Korean-Chinese workers, respectively. Conclusion: The WMSD interventions need to be planned in consideration of different influences of work-related psychosocial and acculturative factors on WMSDs by gender.

This study presents a practical procedure for the Bayesian inversion of geophysical data. We have applied geostatistical techniques for the acquisition of prior model information, then the Markov Chain Monte Carlo (MCMC) method was adopted to infer the characteristics of the marginal distributions of model parameters. For the Bayesian inversion of dipole-dipole array resistivity data, we have used the indicator kriging and simulation techniques to generate cumulative density functions from Schlumberger array resistivity data and well logging data, and obtained prior information by cokriging and simulations from covariogram models. The indicator approach makes it possible to incorporate non-parametric information into the probabilistic density function. We have also adopted the MCMC approach, based on Gibbs sampling, to examine the characteristics of a posteriori probability density function and the marginal distribution of each parameter.

The purpose of this research is to reveal the problems of the Western based development discourse, and to derive the future direction of postdevelopment as sustainable development. This study attempted to reveal the historical process of formation and change on development discourse. Development generally regarded as the overcome of underdevelopment, inducing the marginalization of the South as a place to follow the development model of the North. State based development discourse (Keynesian development discourse) focused on the growth by industrialization, and the supreme aim of the South was to overcome the underdevelopment. Neoliberalism development discourse emphasized on the market principle based on free competition which was recognized as the best way to provide development. However, neoliberalism discourse has been criticized for the concentration of power and inequality of class, causing on the consideration of postdevelopment because of its emphasis on growth rather than distribution and life value. This research revealed the ways of postdevelopment with fair trade and ethical consumption. However, fair trade and ethical consumption discourses clearly show somewhat limitation subsuming into neoliberal development discourse. In this respect, future ways for postdevelopment have to consider the overcoming of powers based on market and capital, and to orient into the value of redistribution in development process.

This study is positive research to figure out enculturation types and to analysis influence of enculturation types on life's satisfaction of the marriage immigrant women. By precedent study, enculturation types was classified by integration factor, separation factor, assimilation factor and marginalization factor. To achieve objectives of study, we carried out sampling, survey and statistical analysis. According to result of study, integration factor and assimilation factor were appeared positive influence and separation factor was appeared negative influence statistically on quality of life of them. Therefore for quality of life of the marriage immigrant women, it need to develop interact system with native persons, support opportunity to associate with koreans, and promote fair treatment and interaction of koreans for them. And government have to execute multiculturalism policy more than assimilation policy. this study have that was samples's regional limitation, few variables limitation, and cross-sectional research's limitation. Therefor it needs more wide and depth research than this for future.

In Brazil, racism exists without the clear definition of race. In other words, because there is racism without a clear concept of race, racial issues are complicated in Brazil. Racism is not just a social problem. It is, above all, a political problem that arises from economic separation, exclusion, and marginalization. From the enlargement process of European colonialism, racism has been the most profound and efficient way of governance of social, material, psychological and political domination of Brazil. From this perspective, this study seeks to research racism in Brazil as a race politics. In conclusion, racial discrimination and racial inequality exist in Brazil. Thus, to study the racial discrimination and racial inequalities in Brazil, Chapter 2 examines the origins of racial politics in Brazil. Chapter 3 explores the relations of Brazilian society and races. Chapter 4 examines Black's resistance to racism as a black movement in Brazil. The first half of Chapter 5 looks at 'racial inequality in Brazil' and the latter sees 'racism in Brazil'. Chapter 6, as a conclusion, discusses the challenges and limitations of racial politics in Brazil.

The purpose of this article is to examine the conflicts and political implications of the various linguistic practices concerning how to call old age, and to illuminate the reasons for these conflicts in the cultural sphere. Recently, the issue of proper ways of calling old age has become problematized. As a result, new ways of addressing older people are being devised, which signifies the marginalization of old age. These new ways of calling older people, however, are not settling the problems. It is because the ageist, gender-discriminatory, status-conscious culture of Korea marginalizes the meaning of the various ways of calling old age. As the otherization of old age deepens in the cultural realm, old age becomes a site where various features of marginality accumulate. The academy and the professionals need to be aware of the political implications of the various ways of calling old age, and to strive to surmount discriminatory linguistic practices.
