Development of body hair is an important physiological and cellular process that leads to better adaption in tropical environments for dairy cattle. Various studies suggested a major gene and, more recently, associated genes for hairy locus in dairy cattle. Main aim of this study was to i) employ a variant of the discordant sib pair model, in which half sibs from the same sires are randomly sampled using their affection statues, ii) use various single marker regression approaches, and iii) use whole genome regression approaches to dissect genetic architecture of the hairy gene in the cattle. Whole and single genome regression approaches detected strong genomic signals from Chromosome 23. Although there is a major gene effect on hairy phenotype sourced from chromosome 23: whole genome regression approach also suggested polygenic component related with other parts of the genome. Such a result could not be obtained by any of the single marker approaches.

The aim of affective engineering is to develop a new product by translating customer affections into design factors. Affective data have so far been analyzed using a multivariate statistical analysis, but the affective data do not always have linear features assumed under normal distribution. Rough sets model is an effective method for knowledge discovery under uncertainty, imprecision and fuzziness. Rough sets model is to deal with any type of data regardless of their linearity characteristics. Therefore, this study utilizes rough sets model to extract affective knowledge from affective data. Four types of scent alternatives and four types of sounds were designed and the experiment was performed to look into affective differences in subject's preference on air conditioner. Finally, the purpose of this study also is to extract knowledge from affective data using rough sets model and to figure out the relationships between rough sets based affective engineering method and statistical one. The result of a case study shows that the proposed approach can effectively extract affective knowledge from affective data and is able to discover the relationships between customer affections and design factors. This study also shows similar results between rough sets model and statistical method, but it can be made more valuable by comparing fuzzy theory, neural network and multivariate statistical methods.

The study examined whether children's behavioral problem and self-resilience mediated the association between mothers' democratic parenting and their children's school life adjustment perceived by children. We analyzed data from the fourth Korean Children and Youth Panel Study (KCYPS) that included democratic parenting, behavioral problem, self-resilience, and school life adjustment by 1,971 mothers and fourth grade elementary school children. We identified structural relationships among the variables using SPSS 18.0 and AMOS 18.0 applying structural equation modeling. The measurement model and structure model had a favorable goodness of fit and the results of structure models on each path were as follows. First, school life adjustment had positive correlations with mother's democratic parenting and self-resilience, but there was a negative correlation between school life adjustment and behavioral problems. Second, the relationship between mother's democratic parenting and self-resilience was mediated by behavioral problems and behavioral problems; in addition, self-resilience mediated the relationship between mother's democratic parenting and school life adjustment. The results of this study suggested that children's school life adjustment and children's confidence to control behavioral problems could improve by promoting self-resilience. If fourth grade children could perceive mother's parenting as affection, monitoring children's behavioral problems could be reduced, and children's self-resilience and school life adjustment could be increased.

Purpose: The purpose of this study was to review the concept of Mother-Child Interaction (MCI) as well as its theoretical model and measurement methods. Methods: A review of related theories and research was done to identify the concept and present status of MCI measuring techniques. Results: The concept of MCI contains the two aspect of attachment and child rearing. MCI is unique in that it includes a dyadic process. The concept of MCI was developed based on attachment theory, Barnard's theory, and the goodness of fit model, MCI involves sensitivity, responsiveness, reciprocity, contingency, mutual satisfaction, and child developmental stimulation including positive and negative affection. Most instruments involved observation, especially in structured situations, and most were developed for mother-infant interaction. Conclusion: MCI is a reciprocal, goal-oriented partnership process and is an ongoing process during childhood. Instruments for measuring MCI for preschoolers as well as appropriate self-reporting instruments need to be developed for wide use in practice and in research.

The purpose of this study is to construct a structural equation model and to analyze causal relationships among variables related to attitudes to science using structural equation modeling(SEM) with LISREL VII. The sample consisted of 483 10th grade boys from a general high school in Pusan, Korea. The questionnaires (ABC-attitude scale: affection, behavioral intention, cognition scale of attitude towards science) were developed by the researcher through a pilot study. And other instruments have modified previous ones. Five instruments were used in this study: GALT(group assessment of logical thinking), MTSlS(modified test of science inquiry skill), ABC-attitude scale, MSAS(modified scientific attitude scale), CSAT(common science achievement test). Structural equation modeling with LISREL VII($J\ddot{o}reskog$ & $S\ddot{o}rbom,$ 1993) was employed to estimate the causal inferences about hypothesized relationships among observed data sets. Three competing models consisted of five latent variable(scientific thinking ability, science inquiry skill, attitude towards science, scientific attitude, science achievement) - lP(inquiry preceding) model, AP(attitude preceding) model and AM(attitude mediating) model - were developed. Among these competing models, IP model satisfied the observed data sets. The causal relationships among "attitudes to science" and other latent variables were reliably identified. According to the results of the present study, science inquiry skill was the most significant variable that can predict science achievement. But scientific thinking ability has not directly influenced science achievement. This study suggests that inquiry based teaching-learning processes should be offered to students for improvement of science achievement. At the same time, it seems to be important to develop positive attitude towards science. Understanding of relationships among variables related to attitudes to science will be helpful to the development of science curriculum and to the design of science teaching and learning process. LISREL has been recognized as a useful approach in testing a SEM. However, in this study, LISREL approach was estimated as much more useful method for research design.

Purpose: The purpose of the study is to analyze the characteristics of emotional intelligence and the variables related to emotional intelligence in a comprehensive manner. In addition, the study intends to present research trends and future research directions of emotional intelligence in a Korean context by analyzing the effects of emotional intelligence and its mechanisms. Research Design, Data, and Methodology: 77 KCI listed studies were selected for the analysis, and the research perspective of emotional intelligence, measurement instruments, empirical research and research methods were analyzed. In addition, research directions were suggested based on the analysis results. Results: The results of the analysis were as follows: First, previous researchers used the ability model of emotional intelligence the most. Second, Previous studies tended to focus on behavioral factors as dependent variables affected by emotional intelligence, in addition to attitudes, affection. Third, there were few studies on the antecedents of emotional intelligence, however, most studies dealt with the consequences of emotional intelligence. Fourth, few studies dealt with moderators between emotional intelligence and dependent variables. Fifth, on the research type, most studies were quantitative studies, however, a few of them were qualitative studies (Literature review, in-depth interview). Sixth, with regard to the analysis level, almost all studies were conducted on the individual level of emotional intelligence, and most studies featured a cross-sectional research design (longitudinal research design was rare). Conclusion: First, from the perspective of emotional intelligence, additional research should be focused on not only the ability model of emotional intelligence but also on the trait model or the mixed model in the future. Second, since emotional intelligence is a multidimensional construct, it is necessary to study the profile of emotional intelligence by employing people-centered as well as variable-centered methods. Third, with regard to empirical studies, additional research is needed with respect to not only the emotional intelligence of the subordinate, but also the emotional intelligence of the supervisor (leader) and the emotional intelligence of the group. Fourth, it is necessary to actively utilize not only cross-sectional design but also longitudinal design, and qualitative research and meta-analysis methods should also be adopted.

Since existing constitutive models developed for confined normal strength concrete overestimate ductility when they are applied to confined high strength concrete, these models cannot be directly applied to confined high strength concrete. In an effort to solve this problem, an accurate stress-strain relationship of the hihg strength concrete needs to be formulated by examining the confinement effects due to increase of the concrete strength. In this study, a constitutive model is developed to express the stress-strain relationship of confined high strength concrete by carrying out regression analysis of the main parameters affection strength and ductile behavior of reinforced high strength concrete columns. Twenty-five test specimens were chosen from the reported experimental studies in the literature. The experimental results of stress-strain relationships of show a good agreement with results of the stress-strain relationships of suggested high strength concrete, covering a strength range between 60 and 124 MPa.

The purpose of this study was to analyse the factors that influence marital conflicts and family life statisfaction, and to predict the future stage of establishment family and extending family, bsed on the theretical model by system approach. For this pourpose, 336 couples of urban households in Seoul were selected. The data were analysed through statistical methods such as, Frequency, percentile, T-test, F-test, ANOVA, Pearson's correlation analysis. The results were as follow : The Martial Conflict and family life satisfaction of surveyed couples were above middle level. It had significantly differences according to family life cycle, husband and wife's educationed levels, husband and wife's occupations, and family income. And Family life satisfaction had significantly differences according to marital conflict. The marital conflict is higher, life satisfaction is lower. In this study, it were appeared that the amount of marital conflict and life satisfaction had differences according to life cycle stages, husband and wife's educational level, husband and wife occupations, and family income, and so that the conflict of phsycho-social system was more affected on family life satisfaction that of managerial system. Such results were indicated that the birth of children was the critical family event affecting on family life satisfaction on and the marital conflict. But the conflict by family's given resources and situational differences also as an environment affection on the family system.
