Purpose: The purpose of this study was to set up a hypothetical model to explain causal relationships among influential variables in the mother-child relationship for Korean infants and toddlers and their mothers. The research was based on Barnard's (1978) mother-child relations model, and goodness-of-fit was examined. Methods: The participants were 207 mothers with infants or toddlers. Data were analyzed using SPSS and AMOS programs. Results: Regarding the influence of the variables on the mother-child relationship between infants and toddlers and their mothers, social support had a 75% explanation of mother-child relationships, and attachment had a 58% explanation of social support. Attachment had both direct and indirect effects on the mother-child relationships, and social support had direct and total effects on the mother-child relationships. Among child-related variables, child temperament had a moderating effect on the mother-child relationships. Conclusion: The findings indicate that the model has utility in developing effective nursing intervention methods to boost mother-child relationships between infants and toddlers and their mothers.

The purpose of this study was (1) to examine the impact of chronic diseases on adolescent's peer relationships, and (2) to investigate the mediating effect of self-perceived health status and resilience on the relationship between their physical health states and peer relationships. The authors used the first-wave panel data from 'the Korean Children-Youth Panel Survey'. The sample included 2,351 first-grade of middle school students(boys 50.1%, girls 49.9%). Among the subjects examined 48.11% had chronic diseases. Using maximum likelihood estimation with Amos18(Arbuckle, 2009), SEM software, structural equation modeling was tested. The major findings were as follows : 1. Adolescents' chronic diseases had a negative impact on peer relationships. 2. Self-perceived health status and resilience had a mediating effect. This suggests that self-perceived health status and resilience could be protective factors when it comes to perceive peer relationships more positively for adolescents with chronic diseases. 3. Resilience was directly affected by self-perceived health status. This indicates that positive self-perception about their health status encourages adolescents with chronic diseases to be more resilient and to more positively affect their perception of their relationships with peers.

This study examined the various pathways from peer relationships to subjective well-being through self-esteem in late childhood. A total of 354 fifth and sixth grade students in elementary school (189 boys and 165 girls) participated in the study. Peer relationships were assessed using the peer rating scale, and self-esteem and subjective well-being were measured using the self-rating scales. The data were analyzed by means of Structural Equation Modeling (SEM). Children's peer relationships affected their subjective well-being directly, as well as indirectly through their self-esteem. Positive relations with peers enabled children to improve their subjective well-being. In addition, those children who possessed good relationships with peers were more likely to perceive themselves as worthy, which led to higher overall levels of happiness and satisfaction in their lives. The study emphasizes the crucial influence of self-esteem on school-aged children's subjective well-being.

Building Information Modelings(BIM) are more complex than typically required for early phase of the design process of a building. Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. This research utilized an ontology to provide an underlying structure of objects and relationships of a building. The OWL is introduced as a main vehicle to encode the information and knowledge about the building structures and spaces. A case study was conducted to develop a structured representation of an ontology where the relationships among the necessary components in the stage of preliminary design were to be automatically utilized to plan on the sizes of each room in a building and structured thoroughly with a simple structured representation.

Since the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China published the GB/T19580-2004: Criteria for Excellence Performance of China, many enterprises in China have adopted the Criteria to enhance their organization business management and to assess or self-assess organization performance. On the bases of both the Criteria for Excellence Performance of China and the survey data from China Association for Quality (CAQ), this paper systematically explores the relationships among 'leadership', 'strategy planning', 'customer and market', 'information, analysis and improvement', 'resources management', 'process management', and 'performance results' by using structural equations modeling and validates some of the anecdotal beliefs in quality management. This quantitative analysis provides a guideline for organizations in China to identify causal linkage among core value of total quality management and to identify strengths, deficiency, and opportunities to enhance competitive advantages and ensure the future business success.

This study examined the cause-and-effect relationships among developmental network characteristics, developmental functions, and career identity. The study analyzed the data of employees with more than two years of experience and a college degree or over qualifications, from domestic companies. For analysis, the structural equation model was applied. Most of all, it was substantiated that the structural relationships among the developmental network characteristics, developmental functions, and career identity. The specific results were as follows. First, tie strength had a positive effect on all of developmental functions but psychosocial support mediated the relationship between the tie strength and career identity. Second, an indirect relationship between indicators of network diversity and identity was not found or the indirect relationship was very weak.

Application of data mining techniques to the world wide web, referred to as web mining, has been the focus of several recent researches. With the explosive growth of information sources available on the world wide web, it has become increasingly necessary to track and analyze their usage patterns. In this study, we introduce a process of pre-processing and cluster analysis on web log data and suggest a distance measure considering the structural relationships between web contents. Also, we illustrate some real examples of cluster analysis for web log data and look into practical application of web usage mining for eCRM.

This work presents an optimality criteria method applicable io the design of plane frames with I-shape sections. All kinds of constraints are treated properly to ensure the mathematical rigour of the method as ever. Among the various properties of a section, the cross-sectional area is chosen as the design variable associated with the member. Then other properties, moment of inertia and depth, are determined from the cross-sectional area using relationships established in advance from the sectional data for AISC standard W shapes. The optimality criteria established in this work is perfect in mathematical terms provided that the relationships between properties of a section are correct. A redesign algorithm is derived relying heavily on the Newton-Raphson method to solve the system of nonlinear constraint equations. A worked example is also Presented.

This study measured the causal relationships among tourist-perceived sacrifice, service quality, service value, and behavioral intention of employee's service. A total of 224 questionnaires were completed. The equation model was used to measure the causal effect. The results demonstrated that the structural analysis result for the data was an excellent model fit. The influences of perceived value and service quality on service value were statistically significant. As expected, service quality and service value had significant effects on behavioral intention. Moreover, overall service quality played a mediating role in the relationship between perceived sacrifice and service value. Service value played a mediating role in the relationship between service quality and behavioral intention.

For constructing the purchasing decision-making model to maximize customer value on the electronic commerce, Means-Ends Network model was used for identifying means and fundamental objectives and their relationships were analyzed by the structural equation. A questionnaire survey of 481 customers in their internet shopping experiences was conducted to extract valid means and fundamental objectives' factors. As a result, 6 means objectives shopping travel, shipping errors, vendor trust, online payment, product choice, and recommender systems and 3 fundamental objectives-shopping convenience, internet ecology, and customer support were founded. Using these 9 factors, structural equation was analyzed 4 times to ensure statistical validities and to establish new interrelationships among them. The results showed that fundamental objectives are affected by the strong relationships within means objectives. This interrelationship with mens and fundamental objectives is interpreted as the purchasing decision-making model to maximize customer value on the electronic commerce in this paper.
