The objective of this paper is to study the establishing system of truck collaboration and to reduce traffic cost for participating transportation enterprises. The system of truck collaboration can enhance the transport efficiency and to reduce traffic cost without new investment for trucks and equipments. The type of truck collaboration should be enumerated (1) the system of head and branch base (2) the system of central terminal (3) the system of separating collection and delivery for cargo (4) the system of cooperating cargo order and truck allocation. The efficiency of truck collaboration is possible to be realized for transportation enterprises, receiver and sender of cargo.

The objective of this paper is to calculate the minimum scale of management for transportation business in order to achieve a form of enterprise. In this study the tracking minimum scale of business is the minimum number of operating trucks. Transportation companies should ensure the number of trucks for a type of business model rather than a means of livelihood model. The method to calculate the minimum number of trucks for the transportation business model can use an approach of either the qualitative and the quantitative technique. This study chooses the quantitative technique to calculate the minimum number of trucks through the analysis of break-even point.

This present study investigated the effects of goal setting methods on sit up performance in elementary school children. Subjects Were 80 pupils from the five grade in elementary school. they were randomly assigned to four conditions : specific goal setting(individual), specific goal-setting(group), nonspecific goal setting(individual), nonspecific goal-setting(group), they practiceed sit-up in class three time a week for weeks according to the experimental treatments. Two way ANOVA indicated that goal setting methods were appeared sigbigicant differences (p <0.05). In the camparison between these two groups, specific goal-stting group was higher than nonspecific goal-setting group in sit-up performance. A review of both laboratory and field studies of the effects of goals setting when performing a task that 90% of th studies specific and challenging goals lead to higer performance than non-specific goals. Goal setting is likely to improve Endurance performance when the goals are specific and sufficiently challenging.
