  • In the modern age. Building is getting higher and larger according to owner and social demands. Now when we are facing the need of the cost down and the reduction of economic loss. In this paper, the characteristics of the present conditions of site management were investigated with the field survey. And The Purpose of this study is to suggest the rational plans of construction planning in site management. The method of site management. however depends on experience of a construction manager. in order to solve this situation, it is necessary to create a method of site management that is adequate for the condition of construction. By cultivating excellent sub contractors, we can expect precise construction with a few experts. improvement in qualify of construction from standardization, computerization of each process. And the expectancies of this paper are that it can be used as efficient data for improvement of system to systematize site management work in Korea.

  • For the continuous development of the manufacturing company, selp-helpㆍdiligence of the individual members of the organization and cooperation system of the sub-department process of the manufacture must operate under rationality. Moreover, perpetual and reasonable improvement on productivity should be focused on. Improvement on productivity implies raising $\ulcorner$output / input$\lrcorner$ ratio, and this does not only implies simple increase of the level of output. Therefore under the theoretical principle, Which is designed to increase the ratio of $\ulcorner$output / input$\lrcorner$ -economically select the relevant $\ulcorner$methodology$\lrcorner$. When rational improvement on productivity $\ulcorner$techniques$\lrcorner$ are properly applied with this methodology, calculated result will come out. The ultimate aim of improving quality does not mean simply reducing the percentage of the defects, but means improving the quality of products, for customer satisfaction. Thus recognize this, we have to contribute to the national economy growth through the enhancement of added value of individual company by $\ulcorner$improvement on quality and productivity, and reduction of the cost$\lrcorner$, $\ulcorner$improvement program on quality and productivity$\lrcorner$ shouldn't be just the parading formality. We can expect the economy result, these are applied to the learning essence and the principle of the improvement.

  • This paper presents a proper rational transfer function synthesis in the continuous time system from noisy measurements. The proposed method identifies the coefficients vector of the transfer function from an overdetermined linear system that develops from rearranging the two dimensional system matrices and output vectors obtained from the observed frequency responses. By computer simulation, the performance improvement is verified.

  • This study aimed to grasp trends of the discourse for improving living conditions carried out since 1920's, when the sense for mending the irrationality of conventional living emerged in various magazines. Among the movement, women intellectuals played an important roles to discuss reforming daily life and unhealthy, inconvenient houseworks. This study found the ideological background and direction of this discourse, and estimated its important role for housing improvement, analyzing the contents of articles published in representative womens' magazines of the modern times. In the discourse, they thought that it was most important to make houseworks brief and efficient, and concentrated on building rational environment for houseworks. As reforming kitchen system, heating system (Ondol) should be separated from cooking system to improve hygienic and economical condition of houseworks. Reformed kitchen would be equipped with new installations for effectiveness, lightened by sunlight through windows, and finished floor with cement and drainage for sanitation. Also, they suggested new ways of living, planning modern houses with reformed kitchen system, thinking about moving path and distance of housewives. This discourse would be a foundation to the change of kitchen system up to now.
