We proposed the speed control of the inverter-fed SLIM(Single-sided Linear Induction Motor) for conveyance system by the decoupled thrust control with DSP board. The voltage equations of SLIM are expressed on the suitable α-β axis by the proposed equivalent circuits, which can analyze the characteristics of the thrust and the normal force and so on. These control methods, which are the slip angular frequency control and the decoupling control for the thrust and normal force by analyzing these parameters can be successfully driven without interfering of each axis. These results exemplified the linear drive of SLIM with the reference value.

Photovoltaic power may vary depending on the various solar cell has an optimal generating point to be able to get the maximum power tracking, in order to get the more power recovery on the switching control system. However the V-I characteristics of the solar array at the frequency have hysteresis, in such high frequency region the conventional controller based on no hysteresis can not be responsible for control of the photovoltaic power system. Therefore, in this paper we proposed a maximum power tracking technique to improve the operation in the region of high frequency[5KHz-30KHz] with added C-R differential circuit for zero cross switching. The distinguishing characteristics of this method is to be controlled by the estimated values of resistive current and sensed photovoltaic terminal voltage do not depend on the operating frequency. the experimental result of the power system is controlled by the proposed sampling.

Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.

Cis-Platinum 투여 환자에서 구토의 조절을 위한 Methylprednisolone과 Metoclopramide의 사용효과

배동한,신영우,조태승 순천향대학교 1989 논문집 Vol.12 No.1

Cis-platinum is a chemotherapeutic agent using in the field of gynecologic malignancy, that can cause severe gastrointestinal disturbances in nearly all patients. Persistent anorexia, nausea, and vomiting may continue for days after chemotherapy and are poorly controlled by conventional antiemetics. Nine patients receiving systemic chemotherapy(PAC protocol) were analysed in a prospective study after administration of three Regimens.(Ⅰ.Ⅱ.Ⅲ) at Obstetrics & Gynecologic department of Soonchunhyang University Chun-an Hospital from Mar. 1986 to Feb. 1987. Patients receiving the combination of methyl-prednisolone and metoclopramide had better relief from vomiting than patients receiving methylprednisolone alone or metoclopramide alone(P<0.05). The results of this study suggest that the combination Regimen of methylprednisolone and metoc- lop- ramide is more effective in controlling Cis-platinum induced emesis.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

고추 역병 저항성 재료의 특성평가와 종자 증식

김동우,김병수,배수연,한정혜 慶北大學校農業科學技術硏究所 2002 慶北大農學誌 Vol.20 No.-

역병 저항성 재료로 도입하여 유지하고 있는 PI123469, PI201234, PI201232, AC2258 (=Line 29), CM334, KC268, KC358, KC820, KC821, KC822, KC823 (Line 29 = AC2258), KC462, KC463, KC464 혹은 이들 유전자원에서 선발한 계통들의 역병에 대한 저항성 검정, 원예적 특성 조사 및 종자 증식을 실시하였다. PI123469, PI201234, PI201232, AC2258, KC823 에서 선발된 계통들이 가장 저항성이 강한 것으로 나타났다. 동일한 유전자원에서 선발한 계통간에도 저항성 수준에서 현저한 차이가 관찰되는 경우가 있었으며, 이러한 경우는 주로 유지 증식과정에 자연교잡이 일어난 결과로 추정되었다. 따라서 순도 높은 저항성 재료를 얻기 위해서는 봉지를 씌워 자식종자를 채종하는 것이 가장 안전하며, 다음으로는 계통 망실 혹은 망상을 이용하는 것이 바람직한 것으로 판단되었다. Resistance to Phytophthora capsici and horticultural characteristics of selections from the resistance sources such as PI123469, PI201234, PI201232, AC2258 (=Line 29), CM334, KC268, KC358, KC820, KC821, KC822, KC823 (Line 29), KC462, KC463, KC464 were evaluated and recorded in the process of seed increase. Selections of PI123469, PI201234, PI201232, AC2258, KC823 (Line 29 = AC2258) of them showed the highest level of resistance. A considerable difference in the level of resistance was observed between lines selected from the same sources. The variation between selections derived from the same source was thought to ve attributable to natural cross-pollination that may have occurred during the seed increase. Therefore, securing self-pollinated seed by wrapping the flower buds before anthesis would be necessary to obtain genetivally pure resistant lines. The next alternative would be to increase the seed in small net houses for single line or field cage.

Objectives : PCR has generally been more sensitive than the conventional microbiological test for the detection of C.trachomatis which has been a leading cause of sexually transmitted disease. The purpose of this study was to evaluate the prevalence of C.trachomatis infection in the patients with pelvic imflammatory disease(PID) and the usefulness of nested PCR as a follow-up test in patiens with C. trachomatis infection after administration of antibiotics. Methods: Cervical swab specimens were obtained from 187 patients with PID and vaginitis attending the Soonchunhyang Chunan Hospital. From the C. trachomatis positive patients, cervical swab specimens were obtained once a week after treatment until PCR tested negative. We performed the nested PCR with Chlamydia-CR kit(Bioneer, Korea.) Results: From 6(5.8%) of 187 cervical swab specimen, C. Trachomatis was detected by nested PCR. These patients were treated with doxycycline and metronidazole for 7 to 14 days. All of 6 C. trachomatis positive patients revealed PCR-negative immediately after the completion of antibiotics treatment. Conclusions: With the above results, the nested PCR is a relatively simple, fast, and practical tool for the detection of C. trachmatis and may be a useful follow-up test for monitoring the treatment effect.

In general, the viscosity of fluid increases as temperature decreases, and decreases as temperature increases. This phenomenon can be explained by decreasing mobility of molecules as temperature decreases. But, we found the opposite phenomenon that viscosity decreases as temperature decreases in particular mixed surfactant system. To analyze this phenomenon, various experiments have been proceeded such as composition (anionic, nonionic, zwitterionic surfactant), variation of zwitterion surfactants, structure of hydrophobic chains, structure of Hydrotrope, variation of pH. Conclusively, controlling the complex of zwitterion and anionic surfactant, we could control the viscosity of mixed surfactant system on variation of temperature. We analyzed this phenomenon theoretically, and then can complete "The technology of viscosity control by temperatre in micellar phase".
