The effect of soil-structure interaction on a single-storey, two-bay space frame resting on a pile group embedded in the cohesive soil (clay) with flexible cap is examined in this paper. For this purpose, a more rational approach is resorted to using the finite element analysis with realistic assumptions. Initially, a 3-D FEA is carried out independently for the frame on the premise of fixed column bases in which members of the superstructure are discretized using the 20-node isoparametric continuum elements. Later, a model is worked out separately for the pile foundation, by using the beam elements, plate elements and spring elements to model the pile, pile cap and soil, respectively. The stiffness obtained for the foundation is used in the interaction analysis of the frame to quantify the effect of soil-structure interaction on the response of the superstructure. In the parametric study using the substructure approach (uncoupled analysis), the effects of pile spacing, pile configuration, and pile diameter of the pile group on the response of superstructure are evaluated. The responses of the superstructure considered include the displacement at top of the frame and moments in the columns. The effect of soil-structure interaction is found to be quite significant for the type of foundation considered in the study. Fair agreement is observed between the results obtained herein using the simplified models for the pile foundation and those existing in the literature based on a complete three dimensional analysis of the building frame - pile foundation - soil system.

Aiming at the mechanical and structural characteristics of the contact zone composite rock, the uniaxial compression tests and numerical studies were carried out. The interaction forms and formation mechanisms at the contact interfaces of different materials were analyzed to reveal the effect of interaction on the mechanical behavior of composite samples. The research demonstrated that there are three types of interactions between the two materials at the contact interface: constraint parallel to the interface, squeezing perpendicular to the interface, and shear stress on the interface. The interaction is mainly affected by the differences in Poisson's ratio and elastic modulus of the two materials, stronger interface adhesion, and larger interface inclination. The interaction weakens the strength and stiffness of the composite sample, and the magnitude of weakening is positively correlated with the degree of difference in the mechanical properties of the materials. The tensile-shear stress derived from the interaction results in the axial tensile fracture perpendicular to the interface and the interfacial shear facture. Tensile cracks in stronger material will propagation into the weaker material through the bonded interface. The larger inclination angle of the interface enhances the effect of composite tensile/shear failure on the overall sample.

This study investigated the effects of mother's psychological control and of teacher-child interaction on young children's self-regulation. Data were collected by surveying 358 young children, their mothers and their 28 teachers. Data were analyzed with statistics using the SPSS Win 18.0 version. The study results are as follows. Mother's psychological control and teacher-child interaction had a significant effect on infant self-regulation. Between them, the child-teacher interaction had a greater effect than the mother's psychological control, affecting emotional regulation more than behavioral regulation. The study results confirmed the mother's psychological control and the interaction of the child-teacher as the variables affecting the children's self-regulation. These results highlight the necessity of continuing education on mother's discipline and teacher's interaction and development of educational program for early childhood pre-service teachers.

The importance of considering soil-structure interaction effect in the analysis and design of RC frame buildings is increasingly recognized but still not penetrated to the grass root level owing to various complexities involved. It is well established fact that the soil-structure interaction effect considerably influence the design of multi-storey buildings subjected to lateral seismic loads. The shear walls are often provided in such buildings to increase the lateral stability to resist seismic lateral loads. In the present work, the linear soil-structure analysis of a G+5 storey RC shear wall building frame resting on isolated column footings and supported by deformable soil is presented. The finite element modelling and analysis is carried out using ANSYS software under normal loads as well as under seismic loads. Various load combinations are considered as per IS-1893 (Part-1):2002. The interaction analysis is carried out with and without shear wall to investigate the effect of inclusion of shear wall on the total and differential settlements in the footings due to deformations in the soil mass. The frame and soil mass both are considered to behave in linear elastic manner. It is observed that the soil-structure interaction effect causes significant total and differential settlements in the footings. Maximum total settlement in footings occurs under vertical loads and inner footings settle more than outer footings creating a saucer shaped settlement profile of the footings. Each combination of seismic loads causes maximum differential settlement in one or more footings. Presence of shear wall decreases pulling/pushing effect of seismic forces on footings resulting in more stability to the structures.

Business firms and consumers exist within a society, and their activities influence a society, because they are not separated from a society. Thus, consumers as well as business firms have been asked to conduct socially responsible actions (i.e., environmentally friendly production and socially friendly activities). Previous researchers have investigated on the relationship between corporate social responsibilities and business performances. For example, researchers have analyzed the effects of corporate social responsibility on consumer's corporate evaluations. The corporate social responsibility is commonly classified into the three dimensions (economic, social, and environmental responsibility). In this paper, we demonstrated that the consumer social responsibility can also be classified into the three dimensions. Previous researchers have shown that the three dimensions of corporate social responsibility influence consumer's corporate evaluation. However, they have not considered the interaction effect of the corporate social responsibility and the consumer social responsibility on consumers' corporate evaluation. Different from the past studies, this study investigated on the interaction effect of consumer social responsibility (economic, social, environmental responsibility) and corporate social responsibility (economic, social, environmental responsibility) on consumer's corporate evaluation. For the study, we collected survey data of 200 consumers and analyzed the interaction effect with ANOVAs. The result showed that the three dimensions of social responsibility to both corporate and consumers influence positively the corporate evaluation. They also showed that the interaction effect of consumer responsibility and corporate responsibility on the corporate evaluation was statistically significant. This implies that it is necessary for corporate to conduct corporate social responsibility differently depending on consumer's activity for consumer social responsibility.

Purpose - In recent years, many companies include franchises have acquire customers by making an online stores and they are carrying out permission marketing activities with e-mail and SMS. Permission marketing requires voluntary customer approval for receiving commercial messages such as cross-selling and upselling. Therefore, it is necessary for the business to induce the customer's acceptance. The purpose of this study is to examine which type of different messages can affect higher in consumer persuasion. Thus, we investigated the impact of descriptive norm message on intention of reception in an online store context, and its interaction with chronic regulatory focus. Research design, data, and methodology - This study hypothesized that the descriptive norm message would affect positive influences to consumers' intension of reception. Specially, this study inquired into whether the interaction effect between descriptive norm and regulatory focus. To verify the hypothesis, we conducted 2 × 2 between-subject factorial design with message type (general message and descriptive norm message) and regulatory focus(promotion focus and prevention focus) as independent variables. Participants of the experiment were assigned to one of 2 kind experimental situations randomly according to characteristics of message type. A total of 131 participants (descriptive norm message: 65, general message: 66) responded for this study. The data were analyzed using frequency analysis, exploratory factor analysis, and two-way ANOVA. Result - The results of the study are as follows. First, we found main effects of the descriptive norm message. The intention of reception were significantly higher in the descriptive norm message rather than general message as in previous researches. Second, interaction effect between the descriptive norm message and regulatory focus was significant. The prevention focus (vs. promotion focus) were hight in a positive behavior intention when the descriptive norm message was given. Conclusions - This study verifies the main effect and interaction effect of descriptive norm message and regulatory focus on the consumers' intention of reception in permission marketing, and persuasive message in the online store context. The results of this study will provide various advantages to companies that want to establish long lasting relationship with customers by carrying out permission marketing in the future.

This study aims to explore the relationship between the spontaneous interactions of office workers and their workspace layout. The spontaneous interactions are captured by the measures regarding the 'visual interaction' between workers in their desk layouts. The measures of visual interaction then are examined by means of the office layout or desk arrangement and the properties of work patterns according to the departments, such as general affairs, sales, research and development, and planning. The study finds four types of office layout ; Type 1 with low visual interaction between workers and high intensity of visual interaction, Type 2 with high visual interaction between workers and high intensity of visual interaction, Type 3 with low visual interaction between workers and low intensity of visual interaction, and Type 4 with high visual interaction between workers and high intensity of visual interaction. The study shows that the patterns of unintentional interaction between workers varies according to the property of work and office arrangement and it also argues that the patterns of office layout are different according to properties of work.
