By manufacturing planter by using scrapped tires such tires can be used more broadly. It contributes to reducing source of environmental pollution and development of landscape facilities. It proposes direction for effective usage of scrapped tires. It is for carrying out study on the effect of new kind of assembly type planter for growing condition of plants. This planter is for using scrapped tires. A number of scrapped tires are combined. Then at No. 2 perforated pipe cap is installed at left and right side of platform. In this way cumulative strata is formed. At the above mentioned cumulative strata tub is inserted. In such tub plants can be planted. In front of above mentioned No. 2 perforated pipe cap ventilation holes are formed. Through above mentioned ventilation holes external air is supplied to root of planted plant. This is about plant which uses scrapped tires and for stimulating growth of plants as described above. Rollers are attached to the platform. Thus it is mobile. Moisture can be reserved inside by putting chaff charcoal bag and charcoal bag as inner liner. Perforated pipe cap passes through tire sidewall therefore ventilation is possible. Water trough is attached at lower part of platform and water supply is controlled. This product is aesthetic and also functionally effective because green net is covered external part of tires. From the outcome of using environmentally safe scrapped tire for growing plants it was confirmed that using perforated pipes above the ground was more conducive to plant growth than such pipes were not used. Thus effect of perforated pipes in stimulating plant growth was confirmed. Trees with which the above mentioned pipes were installed seemed to be more advantageous for taking roots and growing. It appears that such result was stemming from perforated pipes and disposal of supplied water. Thus long term experiment on level of growth of plants in diverse ways should be carried out in future.

Hyo Chang Hong. 2001. Referring Expressions of Late Old English: Discourse Functional Analysis of Apollonius of Tyre. Studies in Modern Grammar 25, 55-73. Old English referring expressions have mostly been dealt with in their sentence-internal grammatical functions. In this paper, I claim that, in addition to their case-marking functions, these referring expressions also played an important discourse-functional role in the development of Late Old English narratives. In particular, it is shown that Old English determiners sum and an, in conjunction with zero article, were major factors that determined the relative importance of the entities introduced by them.
