비성형수술에 삽입하는 사용물로는 자가연골이 가장 이상적이지만 필요한 만큼의 충분한 양을 얻기가 힘들고, 수술시간이 길어지며, 흡수가 일어날 수 있다는 단점이 있다. 이러한 단점을 극복할 수 있는 이종이식물 중에서 고어텍스는 최근에 개발되어 사용이 점차 증가하고 있는 추세이지만 아직까지 고어텍스의 임상적 효용성에 대한 보고는 드물다. 저자들은 고어텍스를 5명의 융비술 환자에서 사용하였는데 3명은 연골과 같이, 2명은 고어텍스 단독으로 사용하였다. 이 중 1명에서 감염이 발생하여 고어텍스를 제거하고 늑연골을 이용하여 융비술을 다시 시행하였고 나머지 4명은 모두 만족스러운 결과를 얻었다. 평균 20개월의 추적관찰에서 이식물의 이동이나 탈출, 피부의 손상 등의 큰 부작용이 없어 고어텍스가 비성형, 특히 융비술에 유용하다고 판단되어 관련문헌 고찰과 함께 보고하는 바이다. Though autogenous cartilage remains the ideal graft material in nasal surgery, situations exist where an alternative or an additional grafting material is needed. Gore-Tex is one of most recently developed alloplastic material and has been widely used for rhinoplasty. But there are few reports about the clinical efficacy of this material in rhinoplasty. The authors used Gore-Tex as a nasal implant in 5 cases of augmentation rhinoplasty. In three patients, the Gore-Tex was used with septal or conchal cartilages because the cartilages were not enough for the needed augmentation. In one patient, the implant was removed due to postoperative infection and subsequent augmentation was done with autogenous rib catilage after infection control. During average 20 months of follow-up, complications such as absorption, mobilization, or extrusion of the implant and thinning of the nasal skin were not found. All patients were satisfied with the surgical results. From these results, Gore-Tex can be considered as an effective material in augmentation rhinoplasty when autogenous material is not available or is not sufficient for the proper augmentation.

Calcium phosphate 결정 성장 최적화를 위한 Ti 표면의 BaTiO_3 박막 형성에 관한 연구

조진우,양홍서,박영준,황규석,송종은,이용렬 전남대학교 치과대학 2001 구강과학 Vol.13 No.2

This study was purposed to establish an optimized manufacturing process for a negatively charged ferroelectric thin flim on titanium substrate in order to develop a new implant system having the mechanical strength and bone forming ability. Ferroelectric materials show an alignment of positive and negative charges by poling treatment. Based on this property, this study was performed with the assumption that the Ca^2+ ions would be easily attracted on negatively charged surface and the attracted cation might behave as nuclei for bone-like crystal grownth in biological solutions. In order to have an osteoinducibility by the ferroelectric thin film coating, continuous and flawless crystalline thin film should be formed with ferroelectricity, and finally should be adequately poling treated. In this study, BaTiO_3 (BTO) was selected as a ferroelectric material. Before thin film coating process, most favorable poling condition was investiged with the evaluation of the difference in calcium phosphate (Ca-P) formation in simulated body fluid (SBF). Moreover, the parameters to form an optimum thin film were studied. Dense bulk BTO disks were fabricate using cold isostatic pressing(CIP) and sintered in air at 1300℃ for 2 hours. Sintered BTO disk was polished, and he crystallinity, microstructure, and ferroelectric characteristics were evaluated using an X-ray diffraction analysis (XRD), a field emission scanning electron microscope (FE-SEM), and an Impedance analyzer. To find the optimum poling condition for the calcium phosphate crystal formation, sintered bulk BTO specimens were treated with either of following poling conditions; 1) room temperature poling treatment [ polarizing field (Ep) = 25kV/cm, at 25℃ for 2 hours], 2) under Tc medium-temperaturepoling treatment (Ep=20kV/cm, from 85˚C to 25˚C for 2 hour), and 3) above Tc high-temperature poling were immesed in simulated body fluid (SBF) for 30 days, and the formation of calcium phosphate (Ca-P) layer n the surface was evaluated. The crystallinity, microstructure, and ferroelectric characteristic of BTO thin film were evaluated withthe variation of final heat treatment. It was performed after establishing the starting substance-solvent mixing ratio, coating times, and pre-heating temperature optimal to form continuous and flawless BTO thin film adequate for having ferroelectricity. Perparation of BTO thin film was made by dipping-pyrolysis technique using metal naphthenates as starting substances. BTO thin films was spin-coated on Ti substrate by dipping-pyrolysis technique using sol obtained by mixing Ba-naphthenate and Ti-naphthenate as starting substances. Pre-firing temperature of BTO thin film was performed at 450℃ because organic-solvent ws completely volatilized without any crystal growth, and the final heat treatment was performed at 600, 700 or 800℃, respectively. The results are as follows; 1. BTO disk sintered at 1300℃ for 2 hours showed average grain size of about 1㎛ and the relative dielectric constant at 1㎑ was abut 3000∼3500. 2. After immersing the sintered bulk BTO poled at respective conditions in SBF for 30 days, Ca-P layers were present on the negatively charged surfaces. In contrary, positively charged Bto surface did not show any noticeable charge of the surface microstructure after SBF immersion. 3. In he case of poling condition 1 and 2 treated with below Tc, Ca/P ratio showed a relatively low value of 1,.2∼1.5. While, in the case of poling condition 3 treated with above Tc, Ca/P ratio was 1.5∼1.67, which is similar to that of biological apatite. This phenomenon demonstrates that poling the BTO above the temperature of Tc is preferable for the Ca-P formation. 4. For thin film BTO coastin, the starting substance was prepared by an equimolar mixing of the Ba and Ti-naphthenate. Dilution of the starting substance with toluene was most appropriate at sol : toluene ratio of 5.2:4.8 Too thin sol produced porosity in film, and too thick sol resulted cracks in the film. By repeating the coating and pre-firing procedure 15 times, homogeneous film of 0.5㎛ thickness could be fabricated, and perfomed well during the poling treatment without breakdown. 5. The heat-treatmen of the BTO thin film at 700℃ produced a homogeneous crystalline structure without heterogeneous TiO2 formation. The BTO thin film heat-treated at 600℃ showed non-crystallinity and no ferroelectricity. Treatment at 800℃ produced heterogeneous TiO2 phase in the film, which is unfavorabe for having ferroelectricity by the distortion of the perovskite structure. The relative dielectic constant at 1 ㎑ was 152 and 112 by heat-treatment at 700 and 800℃, respectively. In summary, these results demonstrated that poling the ferroelectric B_aT_iO_3 surface negatively is effective for the formation of Ca-P layer in simulated body fluids. Poling condition at a temperature cooling from above Tc down to room temperature is most effective. By optimizing the method of BTO thin film coating on metal substrate for the formation of Ca-P layer, the data of this study might be applied for the manufacture of new bioactive implant system.

First, using the adaptive binary method, that effect was certified already, increased the effect of the results. And then, applying table mapping methods that looks for elements from look-up table, decreased the processing time, too. Finally, it was presented that ridge-direction characteristics extracted from these processes can used effectively in the area of fingerprint recognition system.

문제: 조직병리검사의 처방이 복잡하고 전문화됨에 따라 오류처방이 빈번하게 발생되고 이를 해결하기위한 프로세스가 복잡하여 부서간의 갈등과 업무의 가중, 또한 병원 수입 감소가 초래되었다. 목적: 발생된 오류처방의 유형과 발생율, 오류처방을 해결하기 위한 프로세스를 파악하여 이에 대한 문제점을 개선하여 업무의 효율성과 관련부서간의 부가업무 감소와 갈등해소, 더불어 병원수익을 향상시키는 것에 목표를 두고 활동하였다. 의료기관: 서울시에 소재한 종합병원 질 향상 활동: 조직병리검사 처방의 오류처방 발생 원인과 유형, 발생율을 조사하여 원인을 파악하고 개선을 위한 프로세스를 구축하여 질 향상을 도모하였다. 개선효과: 수술실에서 의뢰한 외과 입원환자의 일반조직병리검사 오류율은 개선 전 7.8%에서 개선 후 3.5%, 동결절편조직검사 오류율은 개선 전 28.6%에서 개선 후 0%로 이전보다 모두 개선되었다. 또한 수술실 간호사의 업무 만족도는 일반조직병리검사의 처방시 95%, 동결절편조직검사 처방시 90%로 높은 만족도를 보였다. 단 병리과의 경우 업무가 증가됨에 따라 초과근무시간이 증가하였다.
