The purpose of this thesis is to identify the gardening method of Mus${\bar{o}}$ Soseki by looking into his works. Through this research, life and religious values of Soseki were studied, which gave a better understanding of the garden architect as an individual and seeker of religious truth. Among his works, the most widely known-four ponds, Eiho-ji, Erin-ji, Saiho-ji and Tenryu-ji were studied. The research found that based on the Zen of Buddhism, Soseki symbolized various philosophical ideas into space structures. In addition, through two gardening components, stone buildings and tributaries, he specifically materialized related themes. An absolute religious aesthetics of the creator could be found in the stone buildings that expresses the world of Buddhism and the Chinese letter 'Sim'(heart)-shaped tributaries. By experimenting new method away from a Chinese-style Japanese garden which was widely popular during his time, Soseki devised a garden as residential quarters of a high priest that can be set aside entirely for Zen-study, which became to represent Japanese garden style. If Soseki's gardening method had not been adopted, Japanese gardens could not have been developed as a personal garden that contains symbolic concepts. Unfortunately, in this study, to think of another Zen monk and Mus${\bar{o}}$ Soseki did not study is to compare. also the study on how another Zen monk and Mus${\bar{o}}$ Soseki's compare has to be continued.

The experiment was conducted to determine the performance of DME combustion gas when used as a fuel for DME burner for raising temperature and $CO_2$ concentration in greenhouse and also to examine its effects on chlorophyll content, and fresh and dry weight of lettuce and Chinese cabbage. DME-1 and DME-2 treatments consisted of average DME flow quantity in duct were $17.4m^3min^{-1}$ and $10.2m^3min^{-1}$ respectively to greenhouse-1 and greenhouse-2 and no DME gas was supplied to greenhouse-3 which was left as control (DME-3). DME supply times were $0.5hr\;day^{-1}$, $1hr\;day^{-1}$, $1:30hrs\;day^{-1}$ and $2hrs\;day^{-1}$ on week 1, 2, 3, and 4 respectively. Chlorophyll content and fresh and dry weight of lettuce and Chinese cabbage were measured for each treatment and analyzed through analysis of variance with a significance level of P<0.05. The result of the study showed that $CO_2$ concentration increased up to 265% and 174% and the level of temperature elevated $4.8^{\circ}C$ and $3.1^{\circ}C$ in greenhouse-1 and 2, respectively as compared to greenhouse-3 due to application of DME combustion gas. Although, the same crop management practices were provided in greenhouse-1, 2 and 3 at a same rate, the highest change (p<0.05) of chlorophyll content, fresh weight and dry weight were found from the DME-1 treatment, followed by DME-2. As a result, DME combustion gas that raised the level of temperature and $CO_2$ concentration in the greenhouse-1 and greenhouse-2, might have an effect on growth of lettuce and Chinese cabbage. At end of experiment, the highest fresh and dry weight of lettuce and Chinese cabbage were measured in greenhouse-1 and followed by greenhouse-2. Similarly chlorophyll content of greenhouse-1 and greenhouse-2 were more compared to greenhouse-3. In general, DME was not producing any harmful gas during its combustion period, therefore it can be used as an alternative to conventional fuel such as diesel and liquefied petroleum gas (LPG) for both heating and $CO_2$ supply in winter season. Moreover, endorsed quantify of DME combustion gas for a specified crop can be applied to greenhouse to improve the plant growth and enhance yield.
