In the current research paper, a quasi-3D beam theory is developed for free vibration analysis of functionally graded microbeams. The volume fractions of metal and ceramic are assumed to be distributed through a beam thickness by three functions, power function, symmetric power function and sigmoid law distribution. The modified coupled stress theory is used to incorporate size dependency of micobeam. The equation of motion is derived by using Hamilton's principle, however, Navier type solution method is used to obtain frequencies. Numerical results show the effects of the function distribution, power index and material scale parameter on fundamental frequencies of microbeams. This model provides designers with guidance to select the proper distributions and functions.

In this study, a method for free vibration analysis of wall-frame systems built on weak soil is proposed. In the development of the method, the wall-frame system that constitutes the superstructure was modeled as flexural-shear beam. In the study, it is accepted that the soil layers are isotropic, homogeneous and elastic, and the waves are only vertical propagating shear waves. Based on this assumption, the soil layer below is modeled as an equivalent shear beam. Then the differential equation system that represented the behavior of the whole system was written for both regions in a separate way. Natural periods were obtained by solving the differential equations by employing boundary conditions. At the end of the study, two examples were solved and the suitability of the proposed method to the Finite Element Method was evaluated.

Logistics outsourcing businesses consist of the three main stages of bidding, contracting, and operations. This study focuses on the impacts of factors in the logistics outsourcing stages on outsourcing performance. Key factors in each stage may have direct influences on logistics partnerships and performance. Also, factors of each stage may impact the factors of subsequent stages. The relationships were examined using a structural equation model and verified by PLS (partial least square)-SEM methodology. Study results were as follows. First, the uncertainty of the shipper in the bidding phase affects the flexible contract in the contracting phase, and thus, affects the satisfaction of the logistics outsourcing services. Second, the uncertainty of the shipper in the bidding phase affects operations through contracts, and positively affects logistics outsourcing satisfaction through trust and cooperation.

This research investigates how interest develops across a set of tasks within a course defined by a specific knowledge domain. The current study examined the relationships among self-concept, self-efficacy, Korea-related factors, and evaluation, in the context of learning about the Hanbok costume at Chinese universities. A survey (n=300) was conducted using an online survey website (www.sojump.com) from the 1st to the 25th of June. The structural equation model (SEM) analysis, including total and specific forms of self-evaluation with Hanbok courses, showed that self-concept was positively associated with self-efficacy. Conversely, K-culture interest and K-country image did not significantly affect self-efficacy in clothing, but positively affected Hanbok's self-efficacy. Meanwhile, the more self-efficacy perceived, the higher the level of evaluation. Overall, our findings imply that supporting the students' Korean culture interest, country image perception, and self-concept for regulation can enhance self-evaluation and self-realization success. Theoretical and practical implications for Hanbok courses are discussed.

This paper analyzes the variation law of the pipe lateral vibration characteristics, it was treated as a beam model, and was dispersed into several subunits based on the FEM. The corresponding stiffness and mass matrix of the pipe was deduced by using Hermite interpolation function, and the overall dynamic balance equation was established. The lateral vibration under different pipe lengths, thicknesses and towing speeds are solved by integral method. The results show that the pipe vibration trend decreases first and then increases, and the vibration value at the ore bin is larger than that at the pump set, and the value at the top is the largest, and the least value location can change with the length increase. Increasing length and thickness can reduce lateral vibration value, while increasing speed can increase the value. Neither the thickness nor the towing speed will change the location where the least value occurs. The vibration intensity will increase with the decrease of pipe length and thickness and the increase of towing speed.

South Korea is in the limelight in the past decades as Korean universities races for internationalization. As the number of students studying abroad tremendously increasing, there has been a growing need for higher education institutions to understand international working students' life satisfaction and sense of belonging. The aim of this research is to outline which determinants affects life satisfaction as mediated by sense of belonging. With the samples size of 102 respondents, the proposed research model was examined using structural equation modeling (SEM) and SPSS. Results show that all determinants (Recognition, Quality of Education, Experienced Difficulties in Public Service and Understanding Korean Language) were positively significant toward Sense of Belonging. Likewise sense of belonging holds the positive indirect significant effects of the four determinants to life satisfaction.

Purpose: This study investigates the direct effect of service innovation and corporate image on distribution of behavioral intention and the mediating effect of customer satisfaction on these relationships. Research design, and methodology: The study was conducted through using a questionnaire as a research tool. The data were collected from 444 banking customers who used mobile banking services in Thailand. The data were analyzed through using the structural equation model (SEM). Results: The results demonstrated that service innovation and corporate image had a statistically significant effect on distribution of behavioral intention. Customer satisfaction did not mediate the relationship between service innovation and distribution of behavioral intention. On the other hand, it was found to mediate the link between corporate image and distribution of behavioral intention partially. Conclusions: These results emphasize the significance of strategic marketing practices in shaping customers' perceptions of organizational image, which can subsequently influence their satisfaction with the services. Furthermore, this study highlights the role of service innovation in creating perceived values for customers, leading to a positive attitude toward the services and a higher intention to use them.

The study aims to investigate the factors pursuing the women entrepreneurs to accept Islamic microfinance (IMF) in urban and rural areas of Malaysia. For this purpose, the study applies the Theory of Planned Behavior (TPB) and Innovation and Diffusion Theory to explain Islamic microfinance adoption. Using the structural equation model (SEM) with primary data collected from 384-woman entrepreneurs in Malaysia, the current study uses a 5-point Likert scale. On the basis of theory and collected data, the seven hypotheses are developed. All hypotheses are validated by both directly and indirectly, as well as through a mediating factor. Among the factors, knowledge about IMF and subjective norms significantly influence the acceptance of IMF. On the other hand, the perceived complexity does not show any substantial relationship to the acceptance of IMF. This outcome will be helpful in supporting policymakers, academics, and future studies and must take into account the supported factors. Therefore, the study contributes to develop an innovative framework, to create self-employment for women entrepreneurs.

The purpose of this study was to examine the potential predictors of leisure behavior intention using the theory of planned behavior(TPB). A convenience sample of 369 participants was obtained from university students in Korea and America. For the purposes of this study, potential predictors of leisure behavior intention were selected from the following categories: attitude, subject norm, perceived behavior control, group conformity and face saving. In order to better understand the dynamics of the TPB process that influenced leisure behavior intention, this study used structural equation modeling(SEM) to test the TPB model. According to the results, attitude, subject norm, and perceived behavior control influenced to leisure behavior intention of both Korean and American university students and face saving influenced to leisure behavior intention of Korean university students. However, group conformity did not influence to leisure behavior intention of either Korean and American university students. For future study, more specific and decomposed factors are recommended to understand leisure behavior intention in theoretical way.
