Purpose: The purpose of this study was to identify factors influencing maternal identity of Korean primiparas. Methods: The data were collected by a self-report questionnaire in 2006. The participants were 210 healthy primiparous women who delivered at one of three medical centers and revisited the outpatient department for follow up between 4 to 6 weeks after childbirth. Data were analyzed using the SPSS WIN 17.0 program with descriptive statistics, t-test, one way ANOVA, Pearson correlation coefficient, and stepwise multiple regression. Results: Maternal identity was significantly correlated with Taekyo accomplishment, the culturally based prenatal preparation (p<.001). Transitional gratification to motherhood (p<.001), postpartum depression (p<.001), childcare stress (p<.001), infant temperament (p<.001), and social support (p<.001) were also significantly correlated with maternal identity. The stepwise multiple regression analysis showed that maternal identity was significantly predicted by transitional gratification to motherhood, infant temperament, childcare stress, and Taekyo accomplishment. These variables explained 31.0% of the variance of maternal identity. Conclusion: The results of this study suggest that postpartum nursing interventions to promote maternal identity should focus on reinforcing education and support for reducing childcare stress and infant difficulty, and increasing transitional gratification to motherhood. Also, prenatal encouragement and education for improving Taekyo accomplishment may be helpful to promote maternal identity after birth.

Multi-agent systems often need to achieve the goal of learning more effectively for a task through coordination. Although the introduction of deep learning has addressed the state space problems, multi-agent learning remains infeasible because of the joint action spaces. Large-scale joint action spaces can be sparse according to implicit or explicit coordination structure, which can ensure reasonable coordination action through the coordination structure. In general, the multi-agent system is dynamic, which makes the relations among agents and the coordination structure are dynamic. Therefore, the explicit coordination structure can better represent the coordinative relationship among agents and achieve better coordination between agents. Inspired by the maximization of social group utility, we dynamically construct a factor graph as an explicit coordination structure to express the coordinative relationship according to the utility among agents and estimate the joint action values based on the local utility transfer among factor graphs. We present the application of such techniques in the scenario of multiple intelligent vehicle systems, where state space and action space are a problem and have too many interactions among agents. The results on the multiple intelligent vehicle systems demonstrate the efficiency and effectiveness of our proposed methods.

This study examined the relation between the quality of constructive play and convergent and divergent problem solving. The subjects were 48 five-year-old children. Unit blocks were used to test the quality level of constructive play; a 40 piece puzzle and pattern blocks were used to test convergent problem solving; the pattern blocks also were used to test divergent problem solving. Children's block play was videotaped and pictures were taken of constructions made by children. Data were analyzed by correlation and stepwise multiple regression. Results showed statistically significant correlations between the quality of constructive play and convergent and divergent problem solving. Among the sub variables of constructive play, social play patterns affected convergent problem solving; diversity affected divergent problem solving.

This study investigated effects of parent-related variables on children's coping with stress. Subjects were 409 4th, 5th, and 6th grade children(213 boys and 196 girls) selected from three elementary schools in Seoul and Incheon. Data were analyzed by frequency, mean, and hierachical multiple regression. Major findings were that among the inter-parental conflicts perceived by the children, self-blame and triangulation affects children's coping behavior resulting in children's aggressive and passive/avoidant behaviors. The more children experience parent-related stress, the more children show aggressive and passive/avoidant coping behaviors. With more open-communication in parent-child relations, children's coping shows more active and social support seeking coping behaviors during stress situations.

The major purpose of this study was to investigate the effect of parent-child communication and the inclination of interpersonal relations on the child's loneliness. The participants were 588 children in 5th and 6th grade of the elementary school which is located in Jeonbuk. Data were collected by self-administered questionnaire method. Data were analyzed by statistical techniques such as mean, frequency, percentile, t-test, pearson's correlation, multiple regression analysis using SPSS/Win 12.0 program. The major results of this study are as follows: First, female children's communication with their mother are more open that those of male children and have ostentation-narcism stronger than that of male children. There is no significant difference statistically in children's loneliness by sex. Second, it is indicated that the parent-child communication has negative correlation with children's loneliness and it also has close relations with sub-variables in inclination of interpersonal relations. Third, when investigating how parent-child communication and inclination of interpersonal relations have influences on child's loneliness, they have influences on child's loneliness by the following order: social-friendly, mother-child communication, father-child communication.

Purpose: The main purposes of this study were to assess maternal-fetal attachment (MFA) of the expectant mothers of a fetus with a prenatal diagnosis of congenital heart disease (CHD) and to identify factors associated with MFA. Methods: The methodology was a cross sectional survey study using a self-administered questionnaire. Thirty pregnant women carrying a fetus with a prenatal diagnosis of CHD and 30 pregnant women with a normal fetus were enrolled in this study. The MFA Scale and PPS (The Prenatal Psychosocial Profile) were used to collect data. Data were analyzed using SPSS 20.0 Window version. Descriptive statistics, $X^2$-test and t-test were used to compare the two groups. The factors associated with MFA were identified by multiple regression analysis. Results: There was no significant difference between the two groups in MFA and social support from spouse was the only variable showing a significant difference. The model from the multiple regression analysis explained 33.8% of MFA for both groups. Conclusion: MFA of expectant mothers with a prenatal diagnosis of CHD and of mothers with a normal fetus were not significantly different. It is important that health care providers encourage expectant fathers to support the expectant mothers to increase MFA.

In this paper, I consider the development of methods in contemporary human geography in terms of a dialectical relation of action and structure, and try to draw a new horizon of method toward which geographical research and spatial theory would develop. The positivist geography which was dominent during 1960s has been faced both with serious internal reflections and strong external criticisms in the 1970s. The internal reflections that pointed out its ignorance of spatial behavior of decision-makers and its simplication of complex spatial relations have developed behavioural geography and systems-theoretical approach. Yet this kinds of alternatives have still standed on the positivist, geography, even though they have seemed to be more real and complicate than the previous one, The external criticisms that have argued against the positivist method as phenomenalism and instrumentalism suggest some alternatives: humanistic geography which emphasizes intention and action of human subject and meaning-understanding, and structuralist geography which stresses on social structure as a totality which would produce spatial phenomena, and a theoretical formulation. Human geography today can be characterized by a strain and conflict between these methods, and hence rezuires a synthetic integration between them. Philosophy and social theory in general are in the same in which theories of action and structural analysis have been complementary or conflict with each other. Human geography has fallen into a further problematic with the introduction of a method based on so-called political ecnomy. This method has been suggested not merely as analternative to the positivist geography, but also as a theoretical foundation for critical analysis of space. The political economy of space with has analyzed the capitalist space and tried to theorize its transformation may be seen either as following humanistic(or Hegelian) Marxism, such as represented in Lefebvre's work, or as following structuralist Marxism, such as developed in Castelles's or Harvey's work. The spatial theory following humanistic Marxism has argued for a dialectic relation between 'the spatial' and 'the social', and given more attention to practicing human agents than to explaining social structures. on the contray, that based on structuralist Marxism has argued for social structures producing spatial phenomena, and focused on theorising the totality of structures, Even though these two perspectives tend more recently to be convergent in a way that structuralist-Marxist. geographers relate the domain of economic and political structures with that of action in their studies of urban culture and experience under capitalism, the political ecnomy of space needs an integrated method with which one can overcome difficulties of orthhodox Marxism. Some novel works in philosophy and social theory have been developed since the end of 1970s which have oriented towards an integrated method relating a series of concepts of action and structure, and reconstructing historical materialism. They include Giddens's theory of structuration, foucault's geneological analysis of power-knowledge, and Habermas's theory of communicative action. Ther are, of course, some fundamental differences between these works. Giddens develops a theory which relates explicitly the domain of action and that of structure in terms of what he calls the 'duality of structure', and wants to bring time-space relations into the core of social theory. Foucault writes a history in which strategically intentional but nonsubjective power relations have emerged and operated by virtue of multiple forms of constrainst wihthin specific spaces, while refusing to elaborate any theory which would underlie a political rationalization. Habermas analyzes how the Western rationalization of ecnomic and political systems has colonized the lifeworld in which we communicate each other, and wants to formulate a new normative foundation for critical theory of society which highlights communicatie reason (without any consideration of spatial concepts). On the basis of the above consideration, this paper draws a new norizon of method in human geography and spatial theory, some essential ideas of which can be summarized as follows: (1) the concept of space especially in terms of its relation to sociery. Space is not an ontological entity whch is independent of society and has its own laws of constitution and transformation, but it can be produced and reproduced only by virtue of its relation to society. Yet space is not merlely a material product of society, but also a place and medium in and through which socety can be maintained or transformed.(2) the constitution of space in terms of the relation between action and structure. Spatial actors who are always knowledgeable under conditions of socio-spatial structure produce and reproduce their context of action, that is, structure; and spatial structures as results of human action enable as well as constrain it. Spatial actions can be distinguished between instrumental-strategicaction oriented to success and communicative action oriented to understanding, which (re)produce respectively two different spheres of spatial structure in different ways: the material structure of economic and political systems-space in an unknowledged and unitended way, and the symbolic structure of social and cultural life-space in an acknowledged and intended way. (3) the capitalist space in terms of its rationalization. The ideal development of space would balance the rationalizations of system space and life-space in a way that system space providers material conditions for the maintainance of the life-space, and the life-space for its further development. But the development of capitalist space in reality is paradoxical and hence crisis-ridden. The economic and poltical system-space, propelled with the steering media like money, and power, has outstriped the significance of communicative action, and colonized the life-space. That is, we no longer live in a space mediated communicative action, but one created for and by money and power. But no matter how seriously our everyday life-space has been monetalrized and bureaucratised, here lies nevertheless the practical potential which would rehabilitate the meaning of space, the meaning of our life on the Earth.

This study investigates the relationship between South Korean youths' Confucian values and sense of citizen ethics while presenting outlook on the sense of citizen ethics based on the theory of human nature. The purpose of this study, by doing so, is to present educational measures. For this purpose, empirical research method was applied in this study. In the empirical study, youths were surveyed and the answers were statistically analyzed and discussed with a view to achieve the study purpose. In the empirical research part of the study, Korean youths' awareness on Confucian values was examined along with its relationship with the sense of citizen ethics. The effect of Confucian values on sense of citizen ethics and their relationship were analyzed to evaluate the receptivity of youths on Confucian ideas and usefulness of sense of citizen ethics. This study investigated a total of final 311 sets of data from male and female students at middle and high schools located in Seoul, Gyeonggi, South Korea. First, to identify the youths' Confucian values and level of sense of citizen ethics, descriptive statistical analysis was conducted. As a result, the survey subjects were found to have, concerning the Confucian values, world view M=3.54, human relations view M=3.66, morality cultivation M=3.76, and social order M=3.45, higher than 3.0 to represent positive levels. The morality cultivation, in particular, was recorded the highest among all whereas the social order was relatively lower, which represents the degree of relying on Confucian values to establish social order. Second, the sub-variables of Confucian values were verified according to the personal characteristics of the surveyed youths and differences in their entire perception was investigated. As a result, according to gender, morality cultivation was found higher in female students (M=3.85) than in male students (M=3.64). According to the subjective economic level of their household, world view was found higher in upper class (M=3.98) than middle-low class (M=3.25) and low class (M=3.22) while human relations view was found higher in middle-upper class (M=3.79) than low class (M=3.46). As for the family type, morality cultivation was found higher in extended family (M=3.83) than nuclear family (M=3.62); and social order was higher in extended family (M=3.54) than nuclear family (M=3.36). Third, to verify the study theme of identifying the effects of youths' Confucian values on sense of citizen morality, hierarchical regression analysis was employed in this study, which used the multi-level model of multiple regression analysis. As a result, the Confucian values was found to have significant positive (+) correlations with the entire sense of citizen ethics in order of human relations view(${\beta}=.499$), world view(${\beta}=.412$), social order(${\beta}=.341$), and morality cultivation(${\beta}=.241$). Confucian value showed significant positive (+) correlations with autonomy in order of morality cultivation(${\beta}=.458$), human relations view(${\beta}=.454$), social order(${\beta}=.362$), and world view(${\beta}=.158$). Confucian values was found to have significant positive (+) correlations with community spirit in order of human relations view(${\beta}=.295$), social order(${\beta}=.281$), and morality cultivation(${\beta}=.232$). As shown in the findings above, youths' Confucian values was found to have significant positive (+) effects on the sense of citizen ethics. It is noted that the higher the Confucian values, the more positive the sense of citizen ethics would be. Consequentially, the Confucian values was identified to play an important role in the sense of citizen ethics in the modern society. Based on this analysis, this study presented specific measures - the necessity and possibility of education on sense of citizen ethics under the theory of human nature. To this end, this study proposed to find an optimal interface between the contemporary sense of citizen ethics and Confucian ethics through the respect for human life and nature, man of virtue as the ideal human model, and united society as a desirable society model.

Avian influenza (AI) is notorious for its rapid infection rate, and has a serious impact on consumers and producers alike, especially in poultry farms. The AI outbreak, which occurred nationwide at the end of 2016, devastated the livestock farming industries. As a result, the prices of eggs and egg products had skyrocketed, and the event was reported by the media with heavy emphasis. The purpose of this study was to investigate the correlation between the egg price fluctuation and the keyword changes in online news articles reflecting social issues. To this end, we analyzed 682 cases of AI-related online news articles for fourteen weeks from November 2016 in South Korea. The results of this study are expected to contribute to understanding the relationship between the actual price of eggs and the keywords from news articles related to social issues.
