이상을 요약하면 부인과의사는 cervix, vagina, vulva 등에 종양을 가진 환자를 치료하기 전에 multicentric neoplastic change in large epithelial field를 염두에 두어 다른 부위에 종양이 잇는지 여부를 철저히 검사할 것이며 또한 한 부위에 종양을 치료한 후에 주기적으로 다른 부위를 추적 검사하여야 한다. Primary vulva carcinoma is rare disease, and multiple primary malignancy in lower genital tract of the same individual is very rare. A case of vulva ca. arising from labium minor combined with cervix carcinoma in 46 years old multiparous woman was presented. The patients was treated with radical vulvectomy and hysterctomy and she had been followed for 3 years without any complications and evidence of recurrence. And a brief review of the theory of multicentric ongin in lower gentital tract on the literature is made.

In this study, multi-sectoral partial equilibrium and computable general equilibrium models of Taiwan are used to investigate the direct and indirect effects of energy price increases on overall economies and agro-food sector in Taiwan. The results suggest that agricultural prices, production cost would increase between 0.27% to 1.88%, and a reduction in GDP around 0.39% to 0.54%. The negative impact on livestock sector is slightly higher than that on the crop sector. Negative impacts are also observed in the employment and wages. The rising oil price has the potential to discourage production of energy-intensive activity because of the possibility of substitution and adaptations. The growth rate of real GDP will shrink by 0.64% to 1.06% and CPI will increase by 1.17% to 1.95%. Both the agriculture and non-agricultural sector also respond by raising output prices by 0.80% to 1.33%. The rising international oil price has urged the government to take policy actions like using alternative fuels such as biodiesel, bioethanol, and adopting measures to cut down on energy consumptions mainly in transportation sectors in response to public concern over economic shocks.

The AC-to-DC single-phase PWM rectifier for traction applications using high POWE semiconductor, IGCT is made and tested. Parallel operation of two PWM converter is adopted of increasing capacity of converters For reducing harmonics, the harmonic content is eliminated by th phase shift between two converters switching phase The output voltage control is achieved by intern. calculation without detecting the input current. The part of PLL used for controlling power factor i, simply implemented by software.

In general, the hollow jet valve, the fixed cone valve had been used for the urgency released or maintenance of the flow rate. Nowadays, the butterfly valve, the gate valve are applied in economic performance and operation maintenance more than the hollow jet valve, the fixed cone valve. However, in the case of butterfly valve, it should be required the strict application standard to the cavitation coefficient because the structural axis and disk were situated in pipe channel and the occurring the shock problem by Karman Vortex. And, the judgment data for choice were slight lowdown in water supply and drainage facilities standard or Japanese penstock technology standard, various standard of KOWACO etc. Therefore, there were investigated the valve inside phenomenon (cavitation, disk chattering, vibration) by velocity of flow and the stability examination of body by high velocity of flow through flow scale model test using the numerical analysis and PIV to establish the applicable extensibility of the butterfly valve for the urgency released valve.
