총의치 환자에 있어 Permanent record base를 이용한 악간관계 기록
허윤석,신상완 大韓齒科補綴學會 1995 대한치과보철학회지 Vol.33 No.2
When the complete denture is made, the record base for jaw relation is divided into temporary record base and permanent record base. However, The temporary record base include some disadvantages such as, the lackness of intimate contact between model and base, the lackness of retention during the jaw relation registration, When we obtained jaw relation the permanent record bases made from heat curing resin were utilized. We could get several advantages as follows : 1. The permanent record base provided intimate contact between the model and record base. 2. In fabricating occlusal rim on record base, the dimensional change of record base was little because the permanent record base was lesser influenced to thermal change of occlusal rim than the temporary record base. 3. At the stage of jaw relation, the retention of final denture could be early checked. 4. It could be able to get more accurate registration of jaw relation because all procedure were done on the same base during the jaw relation, artificial teeth arrangement, try-in, and final denture construction. 5. Although there was an inconvenience due to double curing procedure, the shrinkage rate in resin polimerization was relatively reduced so that more dimensional stability could be taken

In order to investigate the availability of insect resources for agrobiotechnological or medical purposes, we examined antioxidant (DPPH and FRAP assay) and cell viability by oxidant stress and NO inhibition assay by treatment of the extracts of Statilia maculata Thunberg, Tenodera angustipennis Saussure and Tenodera aridifolia Stoll. We found that Tenodera angustipennis Saussure and Tenodera aridifolia Stoll extract (DW, etanol, methanol) had high levels of anti-oxidant activity, whereas Tenodera aridifolia Stoll extract showed increased cell viability by hydrogen peroxide and inhibition of NO production. These findings suggest that Statilia maculata Thunberg, Tenodera angustipennis Saussure and Tenodera aridifolia Stoll, extract have potentials to be developed for agrobiotechnology or medicinal use, indicating that mechanistic study including inhibition against molecular inflammation will show a possibility for the development of useful insect resources.

The homozygous deletion allele of the angiotensin converting enzyme gene (ACF/DD), homozygous threonine allele of the angiotensinogen gene (AGN/TT), and the 4 allele of the apolipoprotein E gene (apoE/4) are reported to be associated with ischemic heart disease. Ischemic cerebrovascular disease (ICVD) is another atherosclerotic disease, and the effects of these polymorphisms on ICVD have been confusing. In this study, I investigated whether ACF/DD, AGN/TT, and apoE/4 genotypes are associated with ICVD and whether genetic risk is enhanced by the effect of one upon another. I ascertained these genotypes in patients with ICVD (n=121) diagnosed by brain computed tomography. Control subjects for the ICVD were randomly selected from subjects matched for age, gender, and history of hypertension with patients. Frequency of ACF/DD genotype was somewhat higher in the patients with ICVD than in the controls (18% vs. 15%). Incidence of ICVD was higher in subjects with the apoE/4/4 genotype than in the other genotypes (50% vs. 27-29%). Incidence of ICVD was much higher in subjects with the AGN/TT genotype than in AGN/MM genotype (36% vs. 17%). Furthermore, the AGN/TT genotype greatly increased the relative risk for ICVD in the subjects with ACF/DD genotype (80.0% vs. 20.0%, P=0.089). Finally, incidence of ICVD was much higher in the subjects with both apoE/2/4 and AGN/TT genotype than in the other genotypes (83.3% vs. 16.7%, P=O.095). These results suggest that AGN/TT enhances the risk for ICVD associated with ACF/DD and apoE/2/4.

본 논문에서는 일사량과 온도의 조건에 따른 MSX 60 태양광 모듈의 출력을 예측하였다. MATLAB 모의실 험을 통하여 온도, 직렬저항 및 일사량 변화를 고려한 2차원, 3차원 I-V 곡선을 구하였으며, 단락전류(Isc) 3.8 A, 개 방전압(Voc) 21 V, 최대전력(Pamx) 60W 등의 전기적 파라미터 등을 얻을 수 있었다. 한편, 예측한 결과와 실제 태양 광 모듈을 비교하였을 때 모듈의 사양서와 예측 결과 값의 오차율 3 % 이내에 일치함을 보였다. In this paper, we have predicted and analyzed the MSX 60 photovoltaic module's output according to the temperature and solar radiation conditions by MATLAB program. 2 and 3-dimensional I-V curves of the PV module considered temperature, series resistance and solar radiation variation. are shown. Also, calculated PV's electrical parameters are Isc = 3.8 A, Voc = 21 V, Pmax = 60 W. Compared with the actual photovoltaic module's data, these simulated results agreed well with within the manufacturer's maximum error range 3%.
