Eating is an important part for this group. The purpose of this study is to adapt the push and pull theory in order to investigate what would motivate the elderly to consume food away from home. Based on the results of a literature review and an expert panel, a valid questionnaire was developed. The participants in this study were aged above 55 who live in Taichung district. A total of 265 samples were collected. Statistical Package for the Social Sciences （SPSS） and Analysis of Moment Structures （AMOS） were used to analyze the data. The findings revealed that the data fit the model moderately well. Push and pull variables had a significant influence on intention and behavior. Recommendations like marketing strategies that can attract senior citizens and restaurateurs should focus on the key factors when seniors consume food away from home.展开更多

Based on the experimental research on bond-slip performance, a mechanical model of short SRC column in pulling or pushing test is established. By means of the elasto-plasticity theory the explicit formulation of bond-slip constitutive relation τ-s in different anchor-hold place of push and pull member is investigated under the conditions of balance and boundary. The study shows that the constitutive relation is relevant to the embedment length and the thickness of concrete cover. The results are continuous descriptions of bond-slip constitutive relation and can be used to analyze the non-linear performance of SRC members. Results indicate that the principle of the method is correct and it performs well for short SRC column.展开更多
