The severe extrusion of the maxillary [post.teeth after the early loss of the mandibular post.teeth makes the fabrication of the mandibular prothesis difficult, and without proper planning.the treatment results are often unsatisfactoy. Several treatment modalitys have been introducted to correct the interarch space deficency.:Reduction the occlusal surfaces,Crown lengthening,Endodontics & restorative approach,Extraction, Orthodontic intrusion and segmental osteotomy. Because of many advantages,conservative method is widely used if it has no particular limits of treatment adjustment, but the cases of surgical correction indication are found in clinical experience. In our clinic,we corrected severe extruded maxillary post.teeth by performance of a unilateral posterior osteotomy with superior repositioning of the segment and orthodontic intrusion using Skeletal anchorage system,so here we reported the cases with a study of documents.

Universal motors are commonly used for portable tools and other application. The universal motors can be implied AC or DC voltage source. Phase-angle control AC drive systems gain a high popularity due to their simple implementation despite the disadvantage of their poor input power factor especially for large values of phase delay angle. Futhermore it contains a large amount of subharmonic current. But pulse width modulation controlled DC drive systems reduce these problems. This paper compared the harmonic characteristics of phase angle control AC system that is controlled by TCA785 with zero voltage crossing similar to traditional system and DC chopper system that is used in PWM controller.

Purpose and Method: To access the value and results of femoro-femoral bypass for the treatment of unilateral iliac artery occlusion, the clinical data of 53 patients who underwent femoro-femoral bypass graft at Yeungnam University Hospital between January 1994 to December 2000 were analyzed retrospectively. The influence of variables (such as, age, sex, preoperative symptom, risk factors and associated medical illness, status distal artery, preoperative ABI) on the long term patency was evaluated by univariate statistical analysis. Result: The patients were 47 males and 6 females ranging from 37 to 84 years of age. The mean age was 65, with the highest incidence among people in their 60s, followed by those in their 70s and then in their 50s. Associated disease were hypertension in 28 case (52.8%), diabetes mellitus in 10 cases (18.8%), cardiac disease in 19 cases (32.0%) and cerebrovascular disease in 4 cases (7.5%). History of smoking was noted in 77.4% of the cases. Focal stenosis of donor site iliac artery has been found in 2 cases and combined distal outflow occlusion has been found in 21 cases, 2 donor site iliac artery ballon angioplasty was performed preoperatively and 14 adjuvant procedures (9 femoro-popliteal bypas, 2 femoro-tibial bypass, 3 profundoplasty) was performed simultaneously during the operation. Cumulative 1,3,5,-year primary and secondary patency rates of all femoro-femoral bypass were 87.0%, 76.6%, 68.1% and 91.7%, 85.7%, 73.5%. There was no operative mortality and major perioperative complications. Univariate analysis showed that the patients without distal arterial occlusion had significantly better 1-, 3-, and 5-year primary patency rates (93.0%, 89.0% and 74.2% versus 76.6%, 45.9% and 45.9% and 45.9%, P=0.02) compared with the patients with distal arterial occlusion. No significant effect was exerted by all other variables on long term results. Conclusion: These results suggest that femoro-femoral bypass is a sate and durable operation that results in good patency in a good runoff.

Because there were lots of side effects and tolerances to the existing anticancer therapeutics, the experiment extraction the anticancer effct from medicinal herbs is in progress lively. Therefore the purpose of this study were to research the tendency and the course of anticancer studies. To research the tendency of anticancer studies, medicinal herbs of fifty three experimental papers were analyzed and to examine the coures of studies, anticancer papers in the medical world were used. The obtained results were as follows Methods of herbal medicinal treatments were elirmination the pathogenic factor(祛邪 ) and supporting healthy energy(扶正) method used. In this study. immediately tumor bearing and immune response were the most important point. The subject of immediately tumor bearing was not in the specific cancer but in the influence on the life span of general cancerous cells. In the experimental study of immume response, the effect on NK cell activity of medicinal herbs most studied. The combined usage of medicinal herbs and anticaner agent mostly intended to know whether it inhibits the tumor cell growth. The serum test and blood cell nunber test show if medicinal herbs inhibit side effect of anticancer agcnt. More than 80 percents of used medicinal herbs, there were anticancer activities. However anticancer experimental studies using medicinal herbs have two weak points. The one, it was difficult to choose a prescription according to differentiation of symptoms and signs(辨證論) of the Oriental Medicine, because we put to the test not a man but a mouse. The other, as we obseved the indirect effect of the whole physiological regulation caused by synergic effects of the compex prescription, we don't undersstand the detailed mechanism of the herb. Therefore, if the anticancer effect of the herb is proved the experiment, we should research the concrete medical action of medicinal herbs and immunological analysis of herbal medicines to the body.

Background : There is increased recognition that rigorous approach to functional assessment will complement the assessment of clinical status. This study is to develop the appropriate visual function index in Korean patients with cataracts by the assessment of the reliability, validity of visual function indexes including VF-14. Methods : An prospective study was performed with 92 patients who had undergone either one eye or both eye cataract surgery by 3 ophthalmologists practicing at a university-hospital. Patients were interviewed, and clinical data were obtained. Doctors were questioned with self-entered questionnaire forms. Medical record was examined to understand surgery-process. The survey was conducted at 1-2 days before cataract surgery. Results : We used following measures : 7 visual function indexes, global measures of patients' trouble and satisfaction with vision, and best-corrected visual acuity (VA) in each eye. 7 visual function indexes showed a high internal consistency reliability (Cronbach's alpha coefficients ≥0.86). The better visual acuity(operated eye. better eye), the higher patient satisfaction with vision, the lower symptom score, the lower patient trouble with vision was correlated with preoperative visual function index scores. Among 7 indexes, VF-12 with the exclusion of 2 items drivings from VF-14 is a high Cronbach's alpha coefficient and correlation coefficient and the highest R². Conclusion : We conclude that VF-12 is reliable and valid in Korea. So we suggest that in Korea, all items of VF-14, the visual function index, which is in use internationally, ought to be surveyed and VF-12 which has been excluded by 2 items of drivings from VF-14 ought to beused for analysis.

Multiple bilobar liver matastases (MBLM) are the main cause of low resectability in the colon cancer liver metastases. The authors experienced one case of initially non-resectable colon cancer liver metastases. He was curatively and safely treated with a two-stage hepatectomy using the new method of future remnant liver volume growing. A 54-year-old man was referred to our department with the sigmoid colon cancer combined with MBLM, which were checked in two small metastatic lesions in the left lobe and five large sized lesions in the right lobe in the computed tomogram (CT). A laparoscopic assisted anterior resection was primarily performed. We performed the 1^(st) stage hepatectomy 3 weeks after the colon resection. Intra-operative Ultrasonogram (US) found 9 small superficial metastatic lesions in the left lobe. All that lesions were completely removed by non-anatomical wedge resection. An occlusion ballon catheter was placed in the right portal vein through a small branch of the inferior mesenteric vein at that time. The future remnant liver volume was sufficiently increased 3 weeks after the 1^(st) hepatectomy. A right hepatectomy was safely performed 22 days after the 1^(st) hepatectomy. The patient received a regional chemotherapy (interleukin2 based immuno-chemotherapy through hepatic artery) for 4 months, then received 9 cycles of systemic chemotherapy (biweekly Oxaliplation, leucovorin, plus 5-fluorouracil) without any recurrence evidence.

The input voltage of Single-sided linear induction motors (SLIMs) is involved with the time harmonics because most LIM is driven by inverter. Therefore the equivalent circuit for an inverter-fed SLIM has t o be modifided to represent every harmonic present in supply voltage. This paper describes that the dynamic characteristic can be used effectively for analyzing the characteristics of a single-sided linear induction motor using vector driver for PI controller.

The conventional types of X-ray generators were bulky in physical size and heavy in weight, and the control accuracies of the output voltages were not always satisfactory. The high frequency switching inverter and converter technology on power conversion and control systems have been greatly closed up introducing power semiconductor devices. In this paper, the newly developed converter to take the balance of the output voltage versus the ground are also presented in detail to decreasing the volume and the weight of high voltage transformer and to stabilize ripple. This converter consists of the two independent L-C series resonant circuits using the two capacitances and the two primary windings of high voltage transformer.
