마이크로프로세서를 이용한 UTILITY CAR용 CONTROLLER 개발에 관한 연구
안호균,남징락,김태엽 國立 昌原大學校 産業技術硏究所 1999 産技硏論文集 Vol.13 No.-
This paper describes the development of Controller for the Utility Car using Microprocessor. The Utility Car is composed of Controller, separately excited DC motor, battery and potbox. It is easier for a digitalized controller using microprocessor to append new function than an analogized controller. For sensorless current control, the driver is used the feedback voltage of battery.

Basal cell carcinoma(BCC) and squamous cell carcinoma (SCC) are very prevalent neoplasms of the human skin. Ultraviolet radiation in sunlight is a well-established mutagen of the p53 gene and is one of basal cell carcinoma and squamous cell carcinoma. The newly-formed vascular network is important for neoplasms to grow beyond a size of about 1 ㎣. Recent reports have suggested the hypothesis that a mutant p53 protein is closely related with capillary density. Immumohistochemistry for p53 protein and CD34 was performed in 20 cases of BCCs and 14 SCCs to evaluated the relationship between p53 protein and capillary density. The results were as follows:1. The microvessels stained by CD34 were mainly located in the interface of tumor cells and stroma. 2. There was no difference in the microvessel density according to the histologic types and age of the patients, but a higher microvessel density was noted in male patients. 3. The aggressive BCCs and the less-differentiated SCCs showed higher p53 immunostaining. 4. The mean microvessel density of cases showing strong positive immunostaining of the p53 gene(54.73±17.75) was higher than that of others(39.75±18.30). These results suggested that p53 protein expression and microvessel density are not related to the histologic types and age of the patients, but that differentiation and biologic behavior such as the infiltrating property of tumors and the microvessel density are closely related to p53 protein expression.
최대 오차 벡터를 이용한 최적 공간 벡터 변조 기법에 관한 연구

This study proposes a optimized space vector modulation(SVM), which makes a good output current with low total harmonic distortion(THD) and introduces the concept of maximum error vector for new method. The performance of the new modulation technique using maximum error vector is shown by simulation and experiments.

목적: 저자들은 전투 경찰에서 흔히 실시되는 훈련 후 횡문근융해증과의 연관성을 알아보고자 하였다. 방법: 전투경찰 173명을 대상으로 6일간 평균 매일 8시간에 걸쳐 PT체조훈련이 시행하였고,설문조사를 통해 개인당 훈련량을 조사하였다. 결과: 검사 결과 173명 중 98명에서 횡문근융해증을 진단 할 수 있었다. 혈중 마이오글로빈은 훈련량이 증가함에 따라 상승하는 소견을 보였다. 시간 경과에 따른 진행 과정을 볼 때, CPK, AST, 혈중 마이오글로빈은 Background: It is important to recognize rhabdomyolysis in clinical settings, because 10∼30% of rhabdomyolysis patients develop acute renal failure as a complication and patients with such complication have risk of high mortality. Recently, there have bee

고에너지 반사 전자회절기 (RHEED) 및 투과전자현미경(HRTEM)을 이용하여 Si(111)-7×7 면에서의 Ti박막의 성장 mode와 Si(111) 면에서의 C54 TiSi_2의 정합성장을 조사하였다. 초고진공에서 Si(111)-7×7 표면에 상온에서 Ti를 증착하면 Ti/Si 계면에서 비정질의 Ti-Si 중간막이 먼저 형성되고 그 위에 Ti 박막은 다결정으로 성장하였다. 160ML의 Ti 증착한 시료를 초고진공 내에서 750℃로 10분 열처리하면 C54 TiSi_2가 정합성장하였으며 이는HRTEM격자상 및 TED pattern으로 확인할 수 있었다. TiSi_2/(111) 시료를 다시 900℃로 가열하면 TiSi_2 위의 단결정 Si층이 [111] 방향으로 성장하였다. The growth of Ti on Si(111)-7×7 and the formation of epitaxial C54 TiSi_2 were investigated by using relfection high energy electron diffraction(RHEED) and high resolution transmission electron microscopy(HRTEM). Polycrystalline Ti layer is grown on the amorphous Ti-Si interlayer which is formed at the Ti/Si interface by Ti deposition on Si(111)-7×7 at room temperature (RT). HRTEM lattice image and transmission electron diffraction (TED) showed that epitaxial C54 TiSi_2 grown on Si substrate with 160 ML of Ti on Si(111)-7×7 surface at RT, followed by annealing at 750℃ for 10min in UHV. Thin single crystal Si overlayer with [111] direction is grown on TiSi_2 surface when TiSi_2/Si(111) is annealed at ∼900℃ in UHV. which was confirmed by Si(111)-7×7 superstructure.

<P>The purpose of this study was to develop an environmental database for construction finish materials organized by building element as part of an effort to develop an environmental effect assessment program for buildings. To this end, a classification system has been developed for building elements that satisfies the demands from construction project stakeholders to acquire environmental information. Furthermore, among the construction materials, an environmental database of the finish materials has been developed for each building element based on reference substances and the impact indexes of six environmental effect categories of the national LCI DB.</P>
