The study has investigated the loneliness facts influencing the foreign workers in Taiwan, and has discovered the relationship between loneliness and the mediating effects of social support by demographic variables. The target of the study were foreign workers who had came from Thailand, Vietname, and the Philippines. The questionnaires were collected by a hospital and there were 725 valid returns within 35.55% married samples and 64.45% single samples. Using hierarchical regression and path analysis to test the mediating effects of social support, the findings are: 1. work support and health care support were mediating effective for loneliness; 2. native country contact support have direct effects, but the most significant effect was by group support. Regarding the implementation of foreign worker management, it can enforce the already lacking work and health care support of the foreign workers might reduce the negative effect of loneliness, and thus improves the heart, mind and healthy of these workers.

Deep mixing (DM) is the modification of in situ soil to increase strength, control deformation, and reduce permeability. Multi–axis augers and mixing paddles are used to construct overlapping columns strengthened by mixing cement with in situ soils. This method has been used for excavation support to increase bearing capacity, reduce movements, prevent sliding failure, control seepage by acting as a cut–off barrier, and as a measure against base heave. DM is effectively used in excavations both in conjunction with and in substitution of traditional techniques, where it results in more economical and convenient solutions for the stability of the system and the prevention of seepage. Although DM is currently used for excavation control in numerous projects, no standard procedure has been developed and the different applications have not been evaluated. As this technique emerges as a more economical and effective alternative to traditional excavation shoring, there is a need for guidelines describing proven procedures for evaluation of design, analysis and construction. The main objective of this research is to develop a methodology to design retaining systems using deep mixing technology. The method will be evaluated using numerical analysis of one selected case history.

This research investigates the stress anslysis of a tower skirt support respectively by the earthquake and the wind pressure loading. The researcher used the computer-aided design software Solidworks to set up the tower model and he used finite element software ANSYS to analyze the structure. This study aims to analyze the safety of a tower support for different models. By the finite element analysis, this study found the largest displacement of tower, the von Mises stresses, and the safety factor for the skirt support. Among them, the butted-flared skirt support has the smallest displacement. According to the analysis result, the empty crate type design of skirt support revealed the safety factor of stress greater than two, which ensure that the equipment safety and material-savings. It is expected the study findings can provide a reference for designing or repairing a tower skirt support.
