Despite its economic importance, olive flounder Paralichthys olivaceus aquaculture industry is facing a crisis with a continuous production decline. There have been many solutions to overcome the complicate predicament proposed. Increasing genetic diversity and discovering new commercial value through selective breeding are among them. The aims of the present study are to increase the selection power of the golden flounders. We examined the genetic diversity of the breeder population of golden flounders and developed selective markers for the golden flounder population. The 6 microsatellite (MS) markers were selected from melanogenesis-related genes, which are believed to be involved in the pigmentation of fish. All markers were polymorphic (except PO4) and 5 of them had PIC value of 0.6 or above. All makers had distinctive alleles indicating either normal or golden individuals. For examples, from PO4 marker, the frequency of an allele (316) in the golden population was 100% and in normal population was 0% (P<0.001). Although some more studies with more samples at the later generations should be performed to confirm this result, the 316 allele from PO4 marker could be a distinctive tool for decision of the colors in olive flounders at an early stage of the life cycle.

Objectives : This study aimed to examine the association between public social expenditure(PSE) and suicides in the 27 countries of the Organization for Economic Cooperation and Development(OECD) from 1980 to 2003. Methods : The age-standardized suicide rates and their annual change(%) were obtained from the OECD Health Data 2007. As a measure of social protection, the PSE(% GDP) was used. The covariates included the annual divorce rate(/100,000 population), fertility rate(number of children/woman aged 15 to 49 years), GDP per capita(US$ PPP), male unemployment rate(%), life expectancy(years) and alcohol consumption(liter/capita) for each country, which were all obtained from the OECD Health Data 2007 and the OECD Social Indicators 2006. Using hierarchical linear models that included these covariates, the effects of PSE on suicides(Model 1) and the annual percent change (Model 2) were examined(Model 3). Also, sub-sample analyses were done for six countries that experienced political/economic transition. Results : We could not find significant effects of PSE on suicides(Model 1), but we observed significantly negative effects on the annual percent change for men and women(Model 2). Such findings were replicated in the sub-sample analysis, and moreover, the effect size was much larger(Model 3). Conclusions : Our finding suggests that social welfare protection can be a pivotal factor for suicide epidemiology, and especially in countries experiencing a social crisis or transition.

The call-takers in the 119 General Situation Room are playing important roles in recognizing the first crisis situation such as fire, rescue, and emergency, and in starting up the response system. In particular, with regard to the emergency calls, the prompt and accurate surveillance can determine the patient's life as well as the prognosis. Based on April 8-December 31, 2014 Prehospital Care Reports in a metropolitan city, we analyzed the conversation turns and the conversation time between the agent and the caller, and the time of the conversation structure and sequence according to the reception routes and the severity of symptoms. The conversation analysis between the agent and the caller will be useful for the development and improvement of the action manual in the future.

The government has promoted the local fishing port construction project since 1972 for conquest of the crisis of the fishing village by withering of a fishery, the improvement in fishermen's living environment and quality of life, and promotion of fisheries. In order to estimate the local fishing port construction project objective and synthetically, and to grope for the method proposal of system establishment of the project, the monitoring survey was carried out. The monitoring survey was classified into the program and the performance monitoring. The program monitoring was carried out in order to investigate the project fit for the inhabitants of a fishing village. The performance monitoring was carried out in order to investigate the development latent powers, fishery latent powers, tourism latent powers of a fishing village, rural settlement conditions, etc. using various statistical materials. Since investigating the measured value before executing a policy was not completed, the project effect was compared with the measured value of other areas. According to the local fishing port construction project, the development latent powers, fishery latent powers, and tourism latent powers of the fishing village where the project was undertaken improved greatly, and income of the fishing village increased greatly. As a result of comparing project fit in order to evaluate the project, the project fit of the local fishing port construction project area was higher than the non-project area. Desirable method proposal of monitoring survey was established and the method for raising the efficiency of monitoring survey was extracted.

Objectives: This study was conducted in order to determine how the association between socioeconomic position(SEP) and health status changes with age among Seoul residents aged 25 and over. Methods: We utilized the 2001 and 2005 Seoul Citizens Health Indicators Surveys. We used self-rated 'poor' health status as an outcome variable, and family income as an indicator of SEP. In order to characterize the differential effects of socioeconomic position on health by age, we conducted separate multivariate analyses by 10-year age groups, controlling for sociodemographic covariates. In order to assess the relative health inequality across socioeconomic groups, we estimated the Relative Index of Inequality (RII). Results: The risk of 'poor health' is significantly high in low family income groups, and this increased risk is seen at all ages. However, the magnitude of relative socioeconomic inequality in health, as measured by the odds ratio and RII, is not identical across age groups. The difference in health across income groups is small in early adulthood (ages 25-34), but increases with age until relatively late in life (ages 35-64). It then decreases among the elderly population (ages more than 65). When the RII reported in 2005 is compared to that reported in 2001, RII can be seen to have increased across all ages, with the exception of individuals aged 25-34. Conclusions: The magnitude of health inequality is the greatest during mid- to late adulthood (ages 45-64). In addition, health inequalities have worsened between 2001 and 2005 across all age groups after economic crisis.

We have witnessed several kinds of new discourses and practices in health and medicine since the 1970s, such as popular concerns with alternative or complementary medicine, inordinate attention to the promotion of 'healthy' living, rapid resurrection of traditional medicine and ecological management of health. Four structural and situational factors are discussed to underlie these new trends：(i) as 'crisis' in health care of the 1970s was translated into health care reform of the 1980s backed up by neo-liberal political philosophy, the state responsibility for nation's health is being transferred to the individual ；(ii) it resulted from the limits of biomedical paradigm in dealing with chronic diseases；(iii) medico-scientific knowledge of disease is transformed into the subjective discourses and technologies of health in postmodern society ； and (iv) it is deeply associated with the considerable increase in environmental risk perception of health and disease. There are some inherent countervailing forces in these new discourses and practices. First, while they derive from lifestyle-oriented behavioral change, medicalization of life and death is still consolidated in the new trends. Second, inasmuch as new tides are reliant upon science, they. are likely to be remote from techne that means not the practical application of theoretical knowing but a special form of practical knowing. Third, as new discourses and activities accomplished＇in the name of health＇increasingly occupy important strategies in forming the self-identity, they serve as moral apparatus which involves prescriptions about how we should live our lives and conduct our bodies, both individually and collectively. Therefore, two points are suggested to consider seriously whether these streams will succeed in improving the‘healthy’living of all the people. Instead of limiting tile perspective to medicine, healing and health care, a new matrix that interweave welfare, ecology and labor along with them is timely needed for enhancing the health for all. In addition, as the World Health Report fm strongly shows, inequality in health heavily depends upon socio-economic development of a society, and it is not the richest countries that have the best health status, but those that have the smallest income differences between rich and poor.

In this study, the characteristics and patterns of family problems were explored. What constituted family problems, and how those evolved over the period of drastic changes in the Korean society were examined, by analyzing articles published from the 1940s to the 1980s in the four major national newspapers in Korea. A total of 6542 articles related to family problems in the four newspapers, Chosun, Dong-A, Kyunghyang, and Seoul, were used for the content analysis of this study. The main categories of family problems were classified as poverty, marital issues, issues related to children and adolescents, elderly issues, problems in the family as an institution, and the so-called family-lag problem. Each of these categories consisted of several subcategories: The poverty-related problems included the problems caused by difficulty in making a living and instability of living, for example. The marital issues category consisted of conflicts between the couple, unfaithful spouses, domestic violence, divorce, and so on. Issues related to children and adolescents included juvenile delinquency, difficulty in bringing up children, child abuse, single motherhood, and underage household heads, for example. The elderly issues included the anxiety over the aging society, support for the elderly, conflicts between mother-in-law and daughter-in-law, alienation of the elderly, etc. Problems in the family as an institution consisted of the legal issues in such areas as marriage, succession of the family head, and adoption. Lastly, the family-lag problem included confusion over family values, and conflict caused by the inconsistency between consciousness and actual behavior related to the family or family crisis. From the 1940s to the 1980s, family-lag was the most common problem (26.2% of the total articles), followed by issues related to children and adolescents (23.1%), poverty (16.2%), marital issues (15.9%), elderly issues (12.4%), and problems in the family as an institution (6.0%). During the 1940s and the 1950s, poverty was a prominent problem, and in the 1960s, issues related to children and adolescents were most commonly addressed in the articles. In the 1970s and the 1980s, the family-lag problem was the most frequently addressed.

With the intention of revealing that biological determinism is not the truth verified as scientific facts but ideology which conceals or reproduces the white male-centered social order of western capitalism, this article considered the peculiarities of human being from a perspective of cultural anthropology and examined the social contexts of biological determinism. From these studies, it found that the human is not born, but rather become, that biological determinism, from phrenology and social evolutionism to social biology and IQ determinism, emerged for the breakthrough of crisis in which a number of disclosed social contradictions drove the established ruling order into a collapse, and that it cannot but function as dominant ideology rationalizing racial, ethnic, class and gender discriminations. Hence, bioscience must overcome biological determinism in order to be the hope of both all people and all sort of life. But it is without the transformation of unequal structures that the problem of biological determinism cannot be surmountable at all.

In this paper, we propose a portfolio selection model utilizing a Markov chain for investing in the foreign exchange market based on market forecasts and exchange rate movement predictions. The proposed model is utilized to compute optimum investment portfolio weights for investing in margin-based markets such as the FX margin market. We further present an objective investment algorithm for applying the proposed model in real-life investments. Empirical performance of the proposed model and investment algorithm is evaluated by conducting an experiment in the FX market consisting of the 7 most traded currency pairs, for a period of 9 years, from the beginning of 2005 to the end of 2013. We compare performance with 1) the Dollar Index, 2) a 1/N Portfolio that invests the equal amount in the N target assets, and 3) the Barclay BTOP FX Index. Performance is compared in terms of cumulated returns and Sharpe ratios. The results suggest that the proposed model outperforms all benchmarks during the period of our experiment, for both performance measures. Even when compared in terms of pre- and post-financial crisis, the proposed model outperformed all other benchmarks, showing that the model based on objective data and mathematical optimization achieves superior performance empirically.

The collective narratives on global crisis such as the displaced, uneven distribution of resources, invasion of human rights is more than a recurring theme or polemics in the fields of contemporary arts. In the latest projects from Olafur Eliasson, Rirkrit Tiravanija and Ai WeiWei, art works are presented as performative 'platforms' for tackling these undiscriminating reality of human conditions. Here, 'the users' as driving forces of possible change, are postulated as prospective actors/players who lead and collaborate to defy the status-quo. Crossing over the on/off lines, the everyday-activities of exchanging, sharing and networking are strategically deployed and its meaning reconfigured within the context of post/production discourse. This historical, yet unsettling juncture between art and life, dystopian reality and utopian idealism has its formal-conceptual links to Russian Constructivism, Brechtian Learning-Play and Joseph Beuys' Social Sculpture. Based on Nicolas Bourriaud's notion of Postproduction, this paper aims to provide a diachronic analysis on collaborative dispositions of participatory arts practices.
