This study explores the important causal relationship between the public (domestic) and trade (international) disputes of South Korea and China. To understand the relations between the domestic and international disputes, Putnam's study of the two-level game theory has been conducted in order to analyze the effect of complicated social and political frameworks on international trade disputes. Due to the social and political differences between South Korea and China, this study provides three findings based on negotiation, policy, and strategic approaches.

Deep reasoning procedures are model-based, inferring single or multiple causes and/or timing relations from the knowledge of behavior of component models and their causal structure. The overall goal of this paper is to develop an automated deep reasoning methodology that exploits deep knowledge of structure and behavior of a system. We have proceeded by building a software environment that uses such knowledge to reason from advanced symbolic simulation techniques introduced by Chi and Zeigler. Such reasoning system has been implemented and tested on several examples in the domain of performance evaluation, and event-based control.

Unsteady self-excited forces are commonly represented by parametric models such as rational functions. However, this requires complex multiparametric nonlinear fitting, which can be a challenging task that requires know-how. This paper explores the alternative nonparametric modeling of unsteady self-excited forces based on relations between flutter derivatives. By exploiting the properties of the transfer function of linear causal systems, we show that damping and stiffness aerodynamic derivatives are related by the Hilbert transform. This property is utilized to develop exact simplified expressions, where it is only necessary to consider the frequency dependency of either the aeroelastic damping or stiffness terms but not both simultaneously. This approach is useful if the experimental data on aerodynamic derivatives that are related to the damping are deemed more accurate than the data that are related to the stiffness or vice versa. The proposed numerical models are evaluated with numerical examples and with data from wind tunnel experiments. The presented method can evaluate any continuous fitted table of interpolation functions of various types, which are independently fitted to aeroelastic damping and stiffness terms. The results demonstrate that the proposed methodology performs well. The relations between the flutter derivatives can be used to enhance the understanding of experimental modeling of aerodynamic self-excited forces for bridge decks.

The purpose of this study was to analyze a causal relations of children's learned helplessness, stress, perception of self-competence and mother's childrearing attitudes. The subjects were 370 of 4th and 6th grade in elementary school and the second grade in junior high school in Busan and their's mothers. The instruments used for this study were learned helplessness scale, stress scale, self-perception profile for children, and childrearing attitude scale. The data was analyzed with pearson's correlation, multiple regression and path analysis. The major findings of this study were as follows : 1. Children's global self-worth, social self, age and mother's controlling childrearing attitudes predicted children's stress. 21% of the variance of children's stress was explained by these variables. 2. Children's stress, global self-worth, academic and social self predicted children's learned helplessness. 54% of the variance of children's learned helplessness was explained by these variables. 3. 1) Global self-worth was the first contribution and had a indirect effect through stress as well as a direct effect on children's learned helplessness. 2) Children's stress and academic self had direct effect on children's learned helplessness. 3) Children's social self had a indirect effect through stress as well as a direct effect on children's learned helplessness. 4) Mother's affectionate childrearing attitudes had indirect effect through academic, and social self and global self-worth on children's learned helplessness. Mother's controlling childrearing attitudes had indirect effect through stress on children's learned helplessness. Children's age had a indirect effect through global self-worth and stress and children's sex had a indirect effect through social self on children's learned helplessness.

To examine the causal association between story usage and the ability of comprehending social relations, this study analyzed whether the short-term use of story heightened the degree of other-focused attention. To this end, this study randomly assigned 74 participants into three groups(novel, film, and exposition conditions), and participants were exposed to the stimuli for about 30 minutes, and then this study compared the degree of other-focused attention of the three groups. The results suggested that the degree of other-focused attention in the story groups (novel and film) were significantly higher than those in the exposition group. Though causal association between story usage and the ability of comprehending social relations were not clear, via demonstrating the formation of other-focused attention due to short-term use of story, this study provided empirical evidence for the simulation account of story.

South Korea has been reluctant to open its geospatial information overseas to ensure security as a divided country. However, this cannot continue as the domestic and international environments related to geospatial information and the industrial ecosystem of information and communication technologies have been changing dramatically. Within this context, this study aims to analyze the causal relations among relevant variables and how they change and interact with time using a systems thinking process. First, causal maps were created for the domains of national security, map-based convergence service, and corporate competition. Then, the causal maps for each domain were integrated, based on which the points for policy intervention and dominant feedback loops were identified. The analysis results showed that securing the self-sufficiency of domestic geospatial businesses is a key element to determine the whole causal map, and the variable that changes the dominant feedback loop from a vicious circle to a virtuous one is the decision to open geospatial information overseas. In this study, I found the policy leverage that is a policy intervention point that can produce a great effect with little input by building a causal map of the interactions between major variables. This study is significant in that it identified and analyzed the dominant feedback loop as to which causal structure would dominate the system in the long term. The results of this study can be used to discuss not only the impacts of map data overseas opening on the national security and geospatial information industry, but also the interactions in the future when Google or other global companies request to release the geospatial information.

Purpose: This study was done to identify the risk factors influencing drinking permissiveness in university students. Method: The participants in this descriptive survey on causal relations were 219 students enrolled in university who were selected by convenience sampling. The data collected from April to July, 2005 were used in multiple regression analysis to build a prediction model. Results: Differences in drinking permissiveness according to general characteristics were as follows: gender, drinking frequency, drinking in more than one place each time and frequency of excessive drinking. The relationship between drinking permissiveness and amount of alcohol consumption (drinking frequency/month, amount/each time) showed positive correlations. The relationship between drinking permissiveness and motives to drink (social, enhancement, confirmity, coping motives) also showed positive correlations. The causal factors of drinking permissiveness were social motives, capacity/each time and drinking frequency/month. Conclusion: The findings suggest that board intervention programs should be provided to prevent problems of excessive drinking. It is also recommended that a program be developed that can help control the variables identified in this study along with follow up study to verify the model.

With a goal of establishing a marketing strategy which allows businesses to hold a dominant position in beauty service industry, this study has attempted to investigate causal relations among behavioral intentions by customer satisfaction once service recovery strategy is recovered depending on customers' emotional responses against service failure. In order to provide relevant data to make correct decisions during management and marketing planning so that better customer satisfaction can be achieved in the beauty service industry, the results of the previous studies on service failure and recovery strategy in the beauty service industry have been examined. Then after selecting i) the efforts to recover service failure, ii) satisfaction after recovery and iii) behavioral intention after satisfaction as causal variables, the relation among these variables were verified using a structural equation model. As a result, an appropriate recovery strategy which is developed after service failure makes customers have positive behavioral intentions when customer satisfaction is achieved just as described in previous studies. Furthermore, it is a critical fact which helps businesses keep their customers in a mature market, where it is hard to attract new customers and create long-term profit. This study empirically supports information on how service failure and related variables occur in the beauty service industry. It is significant in that it has helped beauty service providers build service recovery-related strategies.

The purpose of this research is to study the causal model among mother related variables, child abuse, and children's emotional maladjustment behaviors. The sample subjects were 542 pairs of fifth and sixth grade elementary school students and first as well as eighth grade middle school students, and their mothers. The major findings of the research are as follows: First, the result of multiple regression analysis on the effects of the maternal parenting stress and marital satisfaction to the children's abuse indicates that stress related to learning expectation and stress related to relationship with child are the significant contributing factor to physical abuse and verbal abuse. Second, the result of multiple regression analysis on the effects of the maternal parenting stress and child abuse to the children's emotional maladjustment behaviors indicate that verbal abuse is the significant contributing factor. Third, looking at causal relations of the maternal variables (maternal parenting stress, marital satisfaction) and child abuse (physical abuse, verbal abuse, neglect) to the children's emotional maladjustment behaviors, maternal variables impact indirectly through the child abuse factor.

Purpose: This study was done to identify the risk factors influencing turnover intention of nurses. Method: The participants in this descriptive survey on causal relations were 756 nurses who were working at a tertiary university hospital in Seoul. The data were put in to multiple regression analysis to build a prediction model. Results: Turnover intention according to general features were shown as following.: Age, Clinical careers, Educational level, Marital status, Economic status(Yearly income). The relationship between turnover intention and job stress had positive correlation. But the relationship between turnover and other factors that job satisfaction, internal marketing, and organizational commitment had negative correlation. The causal factors of turnover intention were organizational commitment, the factors of organizational support and patient/caregiver relationships among subcategories of job stress and the factor of professional position among subcategories of job satisfaction. Conclusions: The findings of study suggest that board intervention program should be provided to prevent problems of turnover. It is also recommended that a program be developed that can help control the variables identified in this study along with follow up study to verify the model.
