I.Influence of deficient or excessive supply of soil moisture. The variety used in this study were Turkish varieties (Smyrna, Samsun, Zichna and Xanthi). Soil moisture content were 30%, 45% and 60% to maximum water-holding capacity for whole growth period. This experiment was carried out to study on the influence of soil moisture to growth and physiology of Turkish varieties. The results are summarized as follow ; a. Dry weight of Samsun and Zichna were-increased at 45% soil moisture content, but Smyrna and Xanthi at 60%. In every soil moisture treatmennt, there were significant difference between D plot and M, W plot but there were no significant difference between M plot and W plot. b. Percentage of dry matter of Smyrna was higher then those of the other varieties in the D plot and W plot. c. Leaf area was increased ill the Samsun of which process was slightly late. In every soil moisture treatment, M plot and W plot were higher than D plot. d. Dry weight per unit leaf area of Smyrna and Zichna were higher than that of Xanthi and Samsun. e. Percentage of dried up leaves was the W plot, and lower at the D and M plot. Smyrna was lower at M plot, Zichna at D and M plot, Xanthi at D plot, but Samsun was no difference among plots. f. In the number of harvested leaves, Smyrna was increased in order W>M>D. In the number of harvested leaves, Smyrna showed difference according to the soil moisture in order W>M>D plot, but Samsun and Zichna showed no difference among each treatments, Xanthi was higher in M plot than D and W plot. From those results, Smyrna showed the highest dry weight on account of the weight of leaf area and percentage of dry weight increased, it was decreased in order Zichna>Samsun Xanthi in the each soil moisture contents. Number of harvested leaves, dried up leaves, leaf area and number of harvested leaves but decreased, percentage of dry matter W treatment increased the number of total leaves, number of dried up leaves, leaf area, percentage of dried up leaves and percentage of dry matter. Yields were the lowest at D treated, there were no difference between M and W treatment. II.Influence of deficient or excessive supply of soil moisture at different growing stages. This experiment was carried out to study on the influence to the growth and physiology according to the soil moisture content during each growth stage on Turkish varieties culture. The varieties used in this study were Samsun, Zichna and Xanthi. The results are summarized as follow; a. Dry leaf weight was decreased in order Zichna>Samsun>Xanthi, there were remakable difference among every variety. In each soil moisture content, weight of dry matter was increased by M and W treated at late stage after MW and MM treated at early and middle stage of growth DWM and MDM plot. Dry leaf weight was decreased at D plot more than M and W plot late stage after early stage was treated by MW and MM. Dry leaf weight was the highest at WWM treate, dthere were high significant difference between varieties and soil moisture contents. b. Percentage of dry matter was decreased in order Zichna=Xanthi>Samsun. In soil moisture treated, it was increased in D treated at the latter stage after MM, MW and WM treated at early and middle stage, but it was decreased by DDM, DWD, MDM, WWD, WMM, and WWM treated. There were high significant interaction between varieties and soil moisture contents. c. Leaf area showed in order Samsun=Zichna>Xanthi. In soil moisture treated, leaf area was increased by WM, MM and MW treated at the middle and latter stage after D treated at early stage, but it was decreased at WWD, WMD, WWM, MWD and MMD treated. d. Dry weight per unit leaf area were no difference among varieties, in soil moisture treated, it was increased by the MMW, MWD, MMD, WMD and DMW treated, weight of per unit leaf area showed significant difference interaction between varieties and soil moisture contents. d. Percentage of dried up leaves showed as follow, Samsun>Xanthi, Samsun=Zichna, Zihna=Xanthi. In soil moisture treated, it was increased by M and W treated at early stage than D treated. f. Number of harvested leaves was decreased in order Xanthi>Samsun>Zichna, there were no difference among soil moisture contents, but appeard high significant difference at the interaction between varieties and soil moisture contents. As the results of this experiment, especially, this experiment will be continue on the influence of soil moisture condition in order to development of home production system.

A prototype of 750 ㎾ direct-drive wind turbine generator system, KBP-750D is under development in Korea. For the gearless, direct-drive prototype a synchronous generator with permanent magnets has been developed. The upwind 3-blade type machine employs variable speed and pitch control. The operating ranges of wind and rotor speed are 3 to 25 m/s and 9 to 25 rpm, respectively. The tip speed ratio of rotor blade is 7.5, designed for power coefficient 0.47. The blade pitch and torque are controlled with the predefined torque-speed curve according to the conditions of wind and public electric grid. This paper describes the outlines of primary components of KBP-750D.
