The mass production of buildings demands standardization of material and industrialization of building elements for a quick and accurate construction. In this paper, it is researched the standardization of title, and so following results are obtained. We use the modular sized tiles, we can save many construction time and costs of building. Accordingly, we will save the time in the design affairs and will make the harmony in the wall and opening. These results are caused less time wasted in cutting and placing materials at the construction site.

In this study, to utilize domestic fly-ash of bituminous briquette order, on the basis of the elementary experiment value, early strength and long term strength of high performance lightweight mortar was experimented by comparison method. The results are as follows : 1. As a result of mix proportion change as 1:1, 1:2 and 1:3, it showed better result than the case that fly-ash is not inputted, in long term strength. 2. If fly-ash is used as a admixture of mortar and concrete, early strength gain is difficult, but in case of mix proportion control which amount of fine aggregate is decreased and same amount of unit cement content is inputted, improvement of early strength and long term age strength is shown in compressive strength appraisement by age. 3. As a result of long term strength gain improvement and fly-ash is substituted for 3types by grade classification method, the best strength ratio is appeared in type 1.

On the basis of literature and empirical studies on relationships of participation in sport as leisure to satisfaction with sport, job satisfaction and life satisfaction, a model of theoretical constructs was established. The empirical data were collected from 219 men and women workers in K industrial estate of city by the way of cluster random sampling. This data were analyzed by the covariance structure method using PC-LISREL Ⅵ. This structural model had a exogenous variable (participation in sport), three endogenous variables (satisfaction with sport, job satisfaction and life satisfaction) and six proposed models concerning them. Although x²was significantly large (p<.05), x²/df (2.05), goodness of fit index(.955), adjusted goodness of fit index (.915), and root mean square residual (.356) showed that this model was fit to the collected empirical data. Accordingly, this model was determined fit and significant without modifying it. The measurement model, and factor loadings and measurement errors of measured variables were presented and found statistically fit. Among six proposed-models, five ones were found statistically significant. Therefore, the conclusions of this study were as follows. First, the structural model established in this study and the measurement model on measured variables of exogenous and endogenous variables were fit to the empirical data obtained for this study. Second, the more participation in sport was, the more job satisfaction and life satisfaction were. Third, the more satisfaction to sport was, the more job satisfaction and life satisfaction were. Fourth, the more job satisfaction was, the more life satisfaction was.
