  • Objective: The aim of this study was to examine the mediated effect of teacher-infant relationships between teacher efficacy and infant's adjustment to child care centers. Methods: A total of 137 child care teachers that lived in Gwangju and Jeollanamdo participated in this study. They were asked to answer two survey questionnaires for two infants. The data were analyzed using analysis of frequency, Pearson's correlation coefficient, and hierarchical multiple regression analysis. Results: The main results are as follows. First, teacher-infant relationships partially mediated the relationship between teacher efficacy and two sub-factors (prosocial behavior and day work adjustment) of adjustment in child care centers. Unlikely as it was, several sub-factors such as positive emotion, peer adaptation, and self-strength were fully mediated by teacher-infant relationships. Conclusion: The present study suggests that it is necessary to improve teacher-infant relationships with teacher efficacy in order to improve infants' adaptation to daycare. In addition, it should be understood that the structural relationship of the influence factors is different depending on the sub-factors of the child care adjustment.

  • A computing procedure is presented to predict the ultimate behavior of prestressed beams under torsion. This computing procedure is based on an extension of the Variable Angle Truss-Model (VATM) to cover both longitudinal and transversal prestressed beams. Several constitutive relationships are tested to model the behavior of the concrete in compression in the struts and the behavior of the reinforcement in tension (both ordinary and prestress). The theoretical predictions of the maximum torque and corresponding twist are compared with some results from reported tests and with the predictions obtained from some codes of practice. One of the tested combinations of the relationships for the materials was found to give simultaneously the best predictions for the resistance torque and the corresponding twist of prestressed beams under torsion. When compared with the predictions from some codes of practice, the theoretical model which incorporates the referred combination of the relationships provides best values for the torsional strength and leads to more optimized designs.

  • Purpose: The purpose of this study was to identify the factors that enhance brand identity among the four relationship factors in the well-being industry: brand relationships, product relationships, employee relationships, and other customer relationships, and to examine the impact between consumers' brand identity and committed behaviors performed by consumers of brand equality, promotion, cooperation, and advocacy. Research design, data and methodology: The models designed in this study were proposed based on prior studies and the survey was conducted on well-being consumers for empirical testing of the models. Valid samples of a total of 350 data collected were analyzed using the SAS 9.4 statistical package programs, and the results for the structural equation model analysis are as follows. Results: First, the three relationships in the brand community have all been shown to improve brand identity, but the product relationship has had a negative significant effect. Second, consumers' brand identity has had a strong effect of promoting both committed behavior, cooperation and advocacy. Conclusions: Based on these analysis results, the theoretical implications of the well-being industry were presented, and effective practical implications were presented to the well-being operators and the community operators of well-being brands.

  • The purpose of this study was to examine the relationships among experience, perceived value, and satisfaction of rural tourists based on the experience economy(Pine, & Gilmore, 1998; 1999). In addition, this study included the moderating effect of length of stay on the proposed relationships. This study was attempt to develop measurement scales based on the theory of experience economy(Pine, & Gilmore, 1998). Data were collected from 481 visitors by field survey from the 10 rural tourism communities. SPSS 20.0 and Amos 18.0 statistical package were used for frequency, reliability, confirmatory factor, and structural equation modelling analysis. The results of a confirmatory factor analysis yielded four dimensions of experience(esthetics, education, escape, and entertainment). The results of structural equation modeling indicated that entertainment, esthetics, and education had positive effects on perceived value, which in turn had a positive effect on satisfaction. In addition, length of stay moderated the relationships among experience, perceived value, and satisfaction. The entertainment and esthetics among experience factor had an effects on perceived value in the group of day visit group, and the entertainment, education, and esthetics among experience factor had an effects on perceived value in the group of stay night group. And the perceived value had a positive effect on satisfaction in the all group. Therefore, in order to increase rural tourists' satisfaction effectively, practitioners needs to develop rural tourism products by considering area of experience economy including tourists' length of stay.

  • The purpose of this study was to analyze the structural model of causal effects of students' variables on science process skills. Student characteristics investigated in the study included attitude related to the science, logical thinking ability, scientific experiences, cognitive style. Covariance structural modeling procedures were used to test causal inferences about hypothesized relationships. The sample consisted of 319 6th grade students and 321 8th grade students in Seoul City, Korea. Five instruments were used in the study, TSPS(test of science process skills), GALT(group assessment of logical thinking), CEFT(children embedded figures test), questionnaire of attitude related to the science, questionnaire of scientific experience. For statistical analysis, the study adopted the structural equation modeling with LlSREL, a computer statistical program developed by J reskog and S rbom. Major findings of the study are as follows:1) Logical thinking ability has a most strong direct effect on science process skills. 2) The structural coefficient of scientific experience influence on attitude related to the science has the greatest direct one than the others in the covariance structural model. According to the results of this study, it is very importance that various scientific experiences, particularly hands-on activity, should be offer to students to improve science process skills. Also, understanding the relationships of student variable to science process skills will be helpful to decision making on the part of curriculum developers, science teachers and researchers.

  • Light-Weight Concrete containing Expanded Poly-Styrene Beads (EPS-LWC) is an approved structural and non-structural material characterized by a considerably lower density and higher structural efficiency, compared to concrete containing ordinary aggregates. The experimental campaign carried out in this project provides new information on the mechanical properties of structural EPS-LWC, with reference to the strength and tension (by splitting and in bending), the modulus of elasticity, the stress-strain curve in unconfined compression, the absorbed energy under compression and reinforcement-concrete bond. The properties measured at seven ages since casting, from 3 days to 91 days, in order to investigate their in-time evolution. Mathematical relationships are formulated as well, between the previous properties and time, since casting. The dependence of the compressive strength on the other mechanical properties of EPS-LWC is also described through an empirical relationship, which is shown to fit satisfactorily the experimental results.

  • The purpose of this study is to show how to gain the morphology of the Hybrid Spatial Structures and to get the geometrical data such as node coordinates, member relationships and graphic images. To form spatial structures, we have developed morphological aspects of general spatial structures, programming process and techniques. Structural design has many processes. Especially, it is very important to consider the determination of structural configuration. Regular Hybrid Spatial Structures have complex configuration, so we need to make use of automated computer process to determine structural shape in Hybrid Spatial Structures. We have applied morphological aspects to double layer plate, single layer dome, double layer dome and tensegrity structure.
