This study investigated causal relations between mother's parenting, self-efficacy, perceived social support, stress, and parenting behaviors, Child's temperament, and the mediational role of mother's parenting self-efficacy. Participants were 404 Korean children and their mothers living in Seoul, Korea. Results showed that mother's parenting self-efficacy was positively related to mother's Warmth-Acceptance, social support, and child's temperament. On the other hand, mother's parenting self-efficacy was negatively related to. mother's Rejection-Restriction, mother's Permissiveness-Nonintervention, and mother's stress. Structural equation modeling indicated that mother's parenting self-efficacy was a significant mediator of the relation between mother's perceived social support and stress, child's temperament, and mother's parenting behaviors including Warmth-Acceptance, Rejection-Restriction and Permissiveness-Nonintervention Child's temperament had an indirect effect on mother's Rejection-Restriction and Permissiveness Nonintervention.

Artificial neural network (ANN) has been extensively used in areas of nonlinear system modeling, analysis and design applications. Basically, ANN has its distinct capabilities of implementing system identification and/or function approximation using a number of input/output patterns that can be obtained via numerical and/or experimental manners. The paper describes a role of ANN, especially a back-propagation neural network (BPN) in the context of engineering analysis, design and optimization. Fundamental mechanism of BPN is briefly summarized in terms of training procedure and function approximation. The BPN based causality analysis (CA) is further discussed to realize the problem decomposition in the context of multidisciplinary design optimization. Such CA is also applied to quantitatively evaluate the uncoupled or decoupled design matrix in the context of axiomatic design with the independence axiom.

This study is designed to examine differences in the well known relationship between risk perception and purchase intention when shopping fashion products Online. In addition, the role of attitude in the process was investigated. 155 Korean college students and 165 U.S. college students participated in the study. Structural equation modeling with risk factors(product delivery, transaction, service) as antecedents, purchase intention as the consequence, and attitude as the mediating variable were analyzed. Results indicated that, for Korean respondents, product delivery risk and transaction risk had significant indirect effect on purchase intention through attitude. Service risk had significant direct effect. For U.S. respondents, product delivery risk had both direct and indirect effect on purchase intention whereas transaction risk had only indirect effect. Service risk did not have significant influence on purchase intention.

Port Authority in Korea does not have financial independence nor fair recruitment practices, thus the prospects of the establishment of the Port Authority is not adequate. Therefore independent and effective port administration cannot be achieved. To overcome this situation, this paper examines the port administration system in Korea and identifies its problems. This paper then provides an 'modeling of Analytical Hierarchy structure' for evaluation. An alternative solution is provided by carrying out a public survey, analysing the significance of the evaluation factor using the techniques of the Analytical Hierarchy Process. The significance of profitability was identified. The role of central government is significant when assessing the public service function of port administration; and the role of the private company is significant when assessing the independence. In addition, the private company is significant when assessing profitability. The private company is the alternative for port administration in Korea, based on the evaluation of various alternatives.

This study investigated the relations between mother's parenting self-efficacy, perceived social support, parenting behavior, and acculturative stress, and young children's problem behavior, focusing on the mediational role of mother's parenting self-efficacy and parenting behavior. Mothers were female international marriage immigrant from China, Philippines, and Vietnam. The participants were 374mothers of young children and teachers of the children in Busan and Gyungnam, Korea. Questionnaires were based on Choe and Chung (2001), Shin(1996), Lee (1996), Hong (1995), and Han(1996). Structural equation modeling indicated that mother's parenting self-efficacy and parenting behavior were significant mediators of the relation between mother's perceived social support and child's problem behavior. The results will be useful for parent training programs for female international marriage immigrant.

This study investigated how perceived social support, self-esteem and parenting attitudes of mothers relates to children's social competence and explored the mediating role of parenting attitudes in multicultural families. Participants were 67 immigrant women and their children aged 4-6. Instruments were the Social Support Scale (Park, 1985), Maternal Behavior Instrument (Lee, 1986), Self-Esteem Scale (Rosenberg, 1965) and Social Competence Scale (Doh & Falbo, 1994). Data were analyzed by Pearson's Correlation and Structural Equation Modeling (SEM). Results indicated that social support perceived by mothers related positively to their self-esteem and positive parenting, and to children's social competence. Mothers' self-esteem related positively to their positive parenting and to children's social competence. Maternal parenting behavior mediated the effects of social support and self-esteem on children's social competence.

This study investigated the relations between young children's self-esteem and mother's parenting self-efficacy, husband support, parenting behavior, and mothers' depression, focusing on the mediational role of mother's parenting self-efficacy and behavior. Participants were 762 young child-mother dyads in Busan and Gyungnam, Korea. Mothers were Korean and female international marriage immigrants from China, Philippines, and Vietnam. Questionnaires were based on Choe and Chung (2001), Hong (1995), Shin (1996), Lee and Song (1991), and Lee (1994). Structural equation modeling indicated that parenting self-efficacy and parenting behavior were significant mediators of the relation between husband support and depression and child's self-esteem in Korea mothers, but in female international marriage immigrants. The results will be helpful for understanding parenting for child self-esteem in both groups.

Information assurance(IA) refers to methodologies to protect engineering information by ensuring its availability, confidentiality, integrity, non-repudiation, authentication, access control, etc. In collaborative design, IA techniques are needed to protect intellectual property, establish security privileges and create "need to know" protections on critical features. Aside from 3D watermarking, research on how to provide IA to distributed collaborative engineering teams is largely non-existent. This paper provides a framework for information assurance within collaborative design, based on a technique we call role-based viewing. Such role-based viewing is achieved through integration of multi-resolution geometry and security models. 3D models are geometrically partitioned, and the partitioning is used to create multi-resolution mesh hierarchies. Extracting an appropriately simplified model suitable for access rights for individual designers within a collaborative design environment is driven by an elaborate access control mechanism.

Car muffler has the role to form the exhaust gas from high temperature- pressure to lower level and reduce the generated noise. Because of this role, its durability decrease as deformation by heat is occurred. This study is to analyze the flow of exhaust gas inside muffler and its coupled thermal deformation with 3-D modeling and ANSYS. There is the fastest flow at the exit of muffler with the maximum velocity of 54 m/s. And the maximum deformation or equivalent stress is shown at this model respectively as 0.00435 mm or 3414.4 MPa by the influence of heat and pressure at part of intersection with inlet and body of muffler.

Glucagon-like peptide 2 receptor, a GPCR, binds with the glucagon-like peptide, GLP-2 and regulates various metabolic functions in the gastrointestinal tract. It plays an important role in the nutrient homeostasis related to nutrient assimilation by regulating mucosal epithelium. GLP-2 receptor affects the cellular response to external injury, by controlling the intestinal crypt cell proliferation. As they are therapeutically attractive towards diseases related with the gastrointestinal tract, it becomes essential to analyse their structural features to study the pathophysiology of the diseases. As the three dimensional structure of the protein is not available, in this study, we have performed the homology modelling of the receptor based on single- and multiple template modeling. The models were subjected to model validation and a reliable model based on the validation statistics was identified. The predicted model could be useful in studying the structural features of GLP-2 receptor and their role in various diseases related to them.
