Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

In this paper, the truncated circular patch antenna is designed with the short pin. The designed antenna has the center frequency of 4.6815GHz and fractional bandwidth of 4.04%. It has been shown that the measured results are increased by 0.87% in the fractional bandwidth, but decreased by 57.5MHz in the center frequency compared to simulations. It seems to be an error in fabrication. Also, the gain in the measurement is 5.39dB. The change of the radiation pattern by the variation of the short pin and the truncation of the patch haven't seriously affect on the performance of antenna. Therefore, the truncated circular patch antenna has the characteristics of extended bandwidth and is easier to match impedance than conventional one.

The relationship of bone mineral density and type of physical exercise was studied in 36 Postmenoposal Women(age 48-57). The exercise group consisted of Weight training([ =9), Aerobic dance(N=8), Swimming(N=9) and the control group consisted of 10 women. Bone mineral density was measured Lumber(L2-L4), Femur neck, Ward's triangle bone density. The results statstically analyzed on these data were summarized as follows: first, Lumber (L2-L4) bone density, Femoral neck bone density, Ward's triangle bone density in Weight training group was significantly higher than in Swimming group and Control group. Secondly, Lumber(L2-L4) bone density, Femoral neck bone density, Ward's triangle bone density in Aerobic dance group was significantly higher than in Swimming group and control group. Thirdly, No significant difference were round for Lumber(L2-L4) bone density, Femoral neck bone density in Weight training group and Aerobic dance group.

In this paper, a novel resonator is designed using the resonant characteristic of the defected ground structure(DGS) from phase noise reduction in oscillator. To confirm the validity of the designed DGS resonator, two kinds of oscillators using DGS resonator and λ/4 microstrip line have been designed and measured in the same configuration except for the configuration of the resonator for the examination of the reduction of phase noise by the DGS. At the fundamental frequency of 8.6GHz, 4.83 dBm output power and -91.7 dBc @100kHz phase noise have been measured for oscillator with DGS resonator, and 5 dBm output power and -72.78 dBc @100kHz phase noise have been measured for one with λ/4 microstrip line. Measurement shows reduced phase noise by 18.92 dB in oscillator with DGS resonator compared to one with λ/4 microstrip line.

In order to know the residual pattern of pesticides and predict to the degradation period until below MRL, we experimented diazinon, iprodinon and chlorfenapyr for shallot. They were the most detected pesticide in shallot by NAQS (National Agricultural product Quality management Service) survey. In this experiment, we sprayed those pesticides 15days before harvest and analyzed 0, 1, 2, 3, 5, 7, 10, 14 day sample to establish logical equation and to calculate DT_(50). During the cultivating period, the residue amount of diazinon was changed from 1.02 mg/kg (0 day) to 0.01 mg/kg (14 day), DT_(50) was 2.19 days, and iprodione was changed from 1.45 mg/kg (0 day) to 0.14 mg/kg (14 day), DT_(50) was 4.15 days, and chlorfenapyr was changed from 1.5 mg/kg (0 day) to 0.01 mg/kg (14 day), DT_(50) was 1.97 days. The DT_(50) of double amount in those pesticides, diazinon was 2.24 days, iprodione was 4.82 days, and chlorfenapyr was 2.24 days, respectively.

We investigated the effect of acid rain on the surface aging, and resistance to tracking and erosion of silicone rubber materials : First, we measured the contact angle, SEM, EDX, and weight reduction to investigate the surface aging caused by immersion in the artificial acid rain solution. From the results of a series of experiments, we concluded that the acid rain attacked the base polymer of the surface, and lead to the depolymerization. Second, we adopted Inclined-Plane Method to measure the resistance to tracking and erosion of silicone rubber, and rather not observably affected the immersed specimen in the tracking resistance than in the erosion resistance.
