Industry related project for a year to develope commercial model of 10 ㎾ dish-Stirling solar thermal power system by modifying possessed one was taken as the objectives. During this project, commercial solar tracking system, control and monitoring system, high durability reflector, and long term operation were performed. The commercial solar tracking system was tested for 4 months to investigate the degree of precision and adapted from October to the control system for an actual operation. Sun tracking accuracy of 3 mrad using modified control system adapted to the Dish-Stirling system was satisfied during the experimental period. The monitoring system displays temperature of receiver's rear plate, cooling water, oil, and etc., engine pressure, electric generation amounts, and generator RPM and weather data of Direct Normal Irradiation, Horizontal Global Insolation, wind speed & direction, and temperature. During 4 months from September to December, operating results had been stored as a excel file automatically. Experimental results of December 16th was selected and shown as a representative data. When DNI increased higher than 800 W/㎡, the solar-to-electric efficiency reached to about 20%. When DNI became 850 W/㎡, the 7 ㎾ power was generated. The solar to electricity efficiency can be reached to 19% under the DNI of 700 W/㎡ and increased to 20% when the constant DNI is over 900 W/㎡ As a results, the power generation trend as a function of DNI can be expressed a liner curve.

The results were summarized as follows : 1. Vespae Nidus is small toxic. The main ingredients of poisoning are essential oil, etc. The ingredients of poisoning from Vespae Nidus mainly can cause slight stimulating symptoms. 2. The representative methods of poisoning treatment in the western medicine are promotion of vomiting, washing out the stomach, supplies of grape sugar and symptomatic treatment, etc. 3. The representative methods of poisoning treatment in the Korean medicine take advantage of herbs, such as Glycyrrhizae Radix(甘草), Camelliae Folium(茶葉), Salviae Miltiorrhizae Radix(丹參), etc. And Korean medical doctors should meet symptoms as patients call for attention. 4. In order to prevent against poisoning of Vespae Nidus, the patients should keep usage, dosage and notes.

본 연구는 전하생성층의 위에 이중전하수송층을 가진 새로운 형태의 oxotitanium phthalocyanine(TiOPc) 유기감광체를 제작하여 감광특성과 캐리어의 이동현상을 연구하였다. 전하생성층은 TiOPc을 폴리비닐부티랄에 분산시켜 두께 0.1 μm로 도막을 형성하고, 전하수송층은 트리페닐아민 유도체와 히드라존을 폴리에스테르와 폴리카보네이트에 분산시켜 두께 5 μm씩 이중으로 도막을 형성하였다. 제작된 TiOPc 유기감광체들은 이온화퍼텐셜측정, 전자스펙트럼측정과 PIDC, XTOF 및 TOF법으로 초기전위 , 광감쇠속도, 반감노광량, 감도, 양자효율과 캐리어의 주행 시간 및 drift 이동도 등을 검토하였다. 연구결과 단일CTL을 가진 감광체보다 이중 CTL을 가진 감광체가 광흡수율, 반감노광량, 전자사진감도와 양자효율 및 drift 이동도가 우수한 경향을 나타내었다. 그리고 CGM과 CTM들 사이의 이온화퍼텐셜차가 적을수록 감광특성과 양자효율 및 drift 이동도가 좋은 것을 알 수 있었다. CTM의 이온화퍼텐셜 Ip(Tm)와 고분자 매트릭스의 이온화퍼텐셜 Ip(Pm)의 차 Δ Ip가 작을수록 감광체의 캐리어 이동도가 증가하였다. The photosensitive properties and carrier transport in the organic photoconductor with double carrier transport layers(DCTL) of polymer matrix doped with two carrier transport materials above carrier generation layer (CGL) containing oxotitanium phthalocyanine(TiOPc) were investigated. The CGL of TiOPc dispersed in poly (vinylbutyral) was formed as tickness of 0.1 μm and the double carrier transport layer was prepared by coating polycarbonate and polyester doped with hydrazone and triphenylamine derivatives as tickness of 0.5 μm, respectively. We have measured photo-induced discharge curve(PIDC), xerographic time-of-flight(XTOF), time-of-fight(TOF), and UV-visible reflective spectrum of these organic photoconductors. In this work, the organic photoconductor with double carrier transport layers was shown better properties in photosensitivity and drift mobility than with the single transport layer. It was found that the characteristics of carrier transport were mainly caused by the ionization potential difference of constitutive materials in molecularly doped polymer.
