  • To improve the efficiency and economics of national defence, the needs for defence M&S systems are greatly increased, but the lack of interoperability and reusability lowers the level of reliability in the existing simulations models. Recently, many research activities have been performed and some conceptual models, such as CMMS, DCMF, and KAMA, were introduced. However, these models don't support the whole process of defence M&S system development nor provide integrated domain knowledge and up-to-date data. In this paper, we analyzed the analysts' guidances and doctrines, which are the basic ingredients for the simulation system development, and proposed a systematic structure for all the defence M&S stakeholders to share the standardized domain knowledge, modeling algorithm and data. This will be a logical bridge between Mission Space and Simulation Space, and provide substantial data sets to build simulation systems.

  • Visual smoke recognition is a challenging task due to large variations in shape, texture and color of smoke. To improve performance, we propose a novel smoke recognition method by combining dual-encoded features that are extracted from both spatial and Curvelet domains. A Curvelet transform is used to filter an image to generate fifty sub-images of Curvelet coefficients. Then we extract Local Binary Pattern (LBP) maps from these coefficient maps and aggregate histograms of these LBP maps to produce a histogram map. Afterwards, we encode the histogram map again to generate Dual-encoded Local Binary Patterns (Dual-LBP). Histograms of Dual-LBPs from Curvelet domain and Completed Local Binary Patterns (CLBP) from spatial domain are concatenated to form the feature for smoke recognition. Finally, we adopt Gaussian Kernel Optimization (GKO) algorithm to search the optimal kernel parameters of Support Vector Machine (SVM) for further improvement of classification accuracy. Experimental results demonstrate that our method can extract effective and reasonable features of smoke images, and achieve good classification accuracy.

  • The purpose of this study was to analyse the principles and methods of Taegyo-Singi with regard to emotion and to review basic informations on Taegyo programs for promoting prenatal development. Taegyo-Singi was analyzed as follows. First, the contents of Taegyo-Singi were classified into principles and methods of Taegyo. Second, the domains of emotion were categorized into emotional perception, emotional expression, emotional understanding, and emotional regulation based on the classification of Mayer and Salovey, and Moon. Third, the contents of Taegyo-Singi were classified into the four domains of emotion. Finally, the reliability and validity of the classification were obtained through inter-rater agreement and analysis of content validity. The results indicated that first, the principles of Taegyo presuppose parental influence on temperament formation, and that the emotional states of the mother in the prenatal and prepregnancy period is the most influential variable in a child's temperament formation. Second, the methods of Taegyo presuppose that the human mind interacts with their behavior. Therefore, through emotional support of family members, 'jon-sim (the serene mind)' and 'chung-sim (the mind from rectitude)' are the key methods of Taegyo. This means that the Korean tradition of Taegyo focused on the emotional domain of development, especially emotional regulation. This coincides with the emotion-focused temperament theory that individual differences in temperament reflect individual differences in emotion.

  • The purpose of this research was to identify the importance of social competence in early childhood, age 3 to 5, by examining the relationship between the children's variables such as gender, age, and temperament, with that of their mothers' emotionality, and the social competence. 72 children in the early childhood age bracket were surveyed. Three major findings were established. Firstly, there were no gender differences in relation to social competence. Children's adaptability and social activity were related to their pro-social behavior and the ability to internalize/externalize problems. Secondly, children exhibited pro-social behavior only when their mother's emotional reactivity was positive. hirdly, children's social competence was influenced by individual variables and their mothers' emotionality. Prosocial behavior, a lower ranking domain, was influenced by children's adaptability and mothers' emotional reactivity. The children's ability to internalize problem was influenced by adaptability. In contrast, The ability to externalize problem was influenced by the range of activities they were involved in. Overall, children's social competence was influenced by their age.

  • This study integrated mother's control behavior of child's misbehavior within social domain analysis and the framework of attributional models of social cognition. The purpose of this study was to identify, compare and contrast maternal attributions and control responses according to child's age and domains of social behavior, and to investigate that mother's social cognition factors(authoritarian attitude and self competence perception) influence material inference and responses for their child's acts. Then this study was to find out whether mother's attribution would mediate their socialization techniques. For empirical research, 654 mothers with 5.6 year old and 8.9 year old children as subjects answered the structured questionnaire. The data were analyzed by frequencies, t-test, oneway ANOVA, and multiple regression. The major findings were as follows: First, according to child's two domains of misbehavior, there were differences in mothers'attribution and control behavior. Also mothers regarded older child's behavior as more dispositional cause and as more deserving of punishment than younger child's. Second, mother's authoritarian altitude of parenting, self-competence perception, and educational level were significantly related to mother's judgment. Third, the more authoritarian attitude mothers had, the more dispositional factor of children they attributed. And the lower self-competence mothers perceived. the more internal factor of child they attributed. Finally, maternal attributions and control responses are interrelated. When they attributed their children's misdeeds to internal dispositions, they respond with more stronger control behavior. The results suggested maternal social cognition mediate socialization behavior.

  • The purspoe of this study is to identify the socialization level of household work of the employed and unemployed housewives and it's related variables in order to provide some fundamental information for the rational and effective performation of the household task. For the purpose of this study, 700 questionnaire were distributed to the employed and unemployed wives who lived in Seoul. The data were analyed by the Frequency distribution, Percentile, t-test, F-test, Duncan's Multiple Range Test, and Multiple Regression Analysis. The main results were as follows : (1) Socialization level of household work of the employed wives was a little below medium point. When the household work was devided into three subdomains, in the domain of food and shelter, the socialization level was far below medium point. In the domain of clothes, the socialization level was a little higher than medium point. Socialization level of household work of the unemployed wives far below average. When the household work was devided into three sudbomains, in the domain of food, clothes and shelter, the socialization level was far below average, too. Socialization level of household work was significantly different according to the employment. (2) Among the background veriables, family income, household work helper, and frequency of leisure activities have a significant influence on the socialization level of the employed wives. Duration of marriage, housewife's education level and house income have a important effect on the socialization level of the unemployed wives background. (3) Among the background variabels of household work, performing competence of household work is powerful effect on the socialization level of the employed wives. And as for the unemployed wives, performing competence of household task and recognition of the velue of household work are significant variables. (4) The psychological variable such as sex-role attitude gave no noticeable influence on the socialization level of employed and unemployed wives. (5) In conclusion, classifing the variances influencing on the socialization level of household work in a measure of respcetive effect, it appears to be performing competence of household task, frequency of leisure activities, house income, sex-role attitued and educational level in the order of their influences for the employed wives. And as for the unemployed wives, it seems to be house income, educational level, performing competence of household work and frequency of leisure activities. To the two sides, the rate of explanation is shown at 35%.

  • It is critical to select an appropriate technology valuation method when the characteristics of a technology and valuation environment are variable. To ensure high quality decision making when selecting a technology valuation method, it is necessary to understand the principles of a good technology valuation method, and define and apply a decision making theory for selecting an optimal method. The authors propose that Axiomatic Design Principles can be applied as a decision making theory. In order to apply Axiomatic Design for this problem, this paper describes four domains(customer, functional, physical, and process domain) and four axioms(independence, information, cost, time axiom) for the decision making process for the optimal technology valuation method. The result of this study will contribute flexibility to the dynamic technology valuation process.

  • The linear programming model is a special form of useful knowledge that is embedded in a database. Since formulating models from scratch requires knowledge-intensive efforts, knowledge-based formulation support systems have been proposed in the Decision Support Systems area. However, they rely on the assumption that sufficient domain knowledge should already be captured as a specific knowledge representation form. Hence, the purpose of this paper is to propose a methodology that finds useful knowledge on building linear programming models from a database. The methodology consists of two parts. The first part is to find s first-cut model based on a data dictionary. To do so, we applied the General Problem Solver(GPS) algorithm. The second part is to discover a second-cut model by applying neural network technique. An illustrative example is described to show the feasibility of the proposed methodology.

  • This study utilized data (a sample of 18,553 people born in 1958 in England, Scotland, and Wales) from the National Child Development Study of 1968 and 1991 to explore the influence of familial difficulties on the internalizing behavioral patterns during the early adolescent period and late life outcomes periods. In this paper, internalizing behavioral problems include 'depression', 'anxiety', 'hostility to adults', 'hostility to children', and 'withdrawal'. Late outcomes were analyzed in two different variables and one marital management domain: 'unemployment', 'seen doctors about emotional problems', 'divorce or separation; never lived as a couple; arguments end in violent behavior' The results indicate that young adolescents who had experienced familial difficulties also have internalizing behavioral problems giving them emotional and behavioral instability. The findings also show that familial difficulties during childhood positively contribute to late life outcomes such as unemployment, emotional problems, and marital management. This study suggests that in order to effectively respond to the needs of children and adolescents who have experienced various familial difficulties, counselors and educators must guide parents.
