The performance of a wet gas meter using water as a sealing liquid was tested by means of a standard gas flow measuring system operating at the room temperature in Korean Research Institute of Standards and Science (KRISS). The original data from the wet gas meter were calibrated by using the humidity measured at the meter exit. As a result, the error of the wet gas meter was decreased remarkably. This means that humidity affects the performance of the wet gas meter significantly. These data and results are expected to be used as bases for further researching and developing various wet gas meters afterwards.

The flow characteristics of small sonic nozzles which were manufactured by ISO 9300 and effects of the shape of nozzle on the measurement of flow rate were found by using numerical analysis. The model with 4.48mm of throat diameter was used and shape of sonic nozzle entrance and flat throat nozzle was adapted as a variable to estimate the effect of the shape of nozzle on the flow rate measurement. The flow of the small sonic nozzle was similar to thar of the ideal gas isentropic and the critical pressure ratio was restored to the stagnation pressure due to the effect of the expansion part. The results showed that the discharge coefficient was smaller than ISO 9300 by 2% in case the shape of nozzle entrance was conical, on the other hand, by 3% in case the shape if nozzle throat was the flat part. However, In both of the two cases the characteristics of discharge coefficient was similar to the nozzle of ISO 9300.

뇌졸중, 파킨슨 병, 척수신경손상 등으로 연하관련 근육들의 협동운동장애가 발생한 환자에서 흡인성 폐렴이 반복되거나 경장영양이 곤란하게 된다. 이러한 경우에 경피내시경하 위루술(percutaneous endoscopic gastrostomy)은 이들 환자의 생명을 유지하는데 매우 중요한 역할을 해 왔다. 위궤양 혹은 위암 등으로 위절제술을 받은 환자에서 위루술 대신에 부득이 경피내시경하 공장루술(direct percutanous endosopic jujunostomy)이 시행되었던 경우는 국내외에 몇 례의 보고가 있다. 본 증례는 과거 후두암 때문에 후두부식도절제술 후 결장 끼어듬(colon interposition) 수술을 받은 65세 남자 환자로 최근 좌측중대뇌동맥 경색으로 연하장애가 발생되었다. 저자들은 이 환자에게 지속적인 영양공급을 위하여 경피내시경하 결장루술을 합병증 없이 시행하였기에 보고하는 바이다. Dysphagia is a loss of coordination in the swallowing musles. It has occurred in patients with cerebrovascualr accident, head injury, Parkinson's disease or cervical cord injury. Dysphagia results in nutritional deficiency or repeated aspiration pneumonia. Percutaneous endoscopic gastrostomy have helped these patients to maintain healthy and save lives. Several cases of direct percutaneous endoscopic jejunostomy have been reported in patients who received gastric resection for a stomach cancer or peptic ulcer hemorrhage. A 65-year-old male patient, who was suffering from dysphagia, whose symptom was caused by left middle cerebral infarction. He was referred to the division of gastroenterology for the provision of permanent enteral feeding. His esophagus had been resected and replaced with a part of colon because of laryngeal cancer 5 years ago. We could not approach the stomach because the angle of anastomosis was acute and the colonic graft was long. We performed direct percutaneous endoscopic colostomy without any complications. Herein, we report on this successful case.

In recent years, robots have been used widely in industrial field and have been expanded as a result of continuous research and development for high-speed and miniaturization. In general, position control of robot manipulators is performed in joint or cartesian coordinates. The objective of this study is to solve the inverse kinematics with a geometric approach, control a position of a manipulator by using the inverse kinematics and the computed torque control, compare the computed torque control with the proportional ad derivative(PD) control for the straight line and circular trajectories and compute an effective moment of inertia for the gain selection. The amount of error was reduced more when using the computed torque control than when using the PD control.

자외선에 의하여 유발되는 염색체 이상과 자매 염색 분체 교환에 미치는 calmodulin의 영향

이천복,김장호 慶星大學校 1993 論文集 Vol.14 No.4

The present study was performed to elucidate not only the effects of clamodulin (calcuim receptor) on the damages and their recovery processes at the chromosomal level, but also the possible relationship between chromsome aberration and sister chromatid exchange(SCE). To obtain a clear understanding of them ,the experiment were undertaken to the effects of trifluoperazine (Tfp; calmodulin inhibitor) on chromosome aberrations and sister chromatid exchchanges induced by ultraviolet light(UV). The results obtained were as follows: 1)Both the chromosome aberrations and sister chromatid exchanges were not induced by the treatment of various concentration and hours of Tfp. 2) Tfp inhibited chromosome aberrations induced by UV-light regardless of the concentration and hours of treatment. 3) In the groups treated with 5μM Tfp for 1 hour after exposure to UV-light, sister chromatid exchanges induced by UV-light were little effected. However, in the groups treated with 10μM or 20μM Tfp, sister chromatid exchanges induced by UV-light increased with Tfp unlike chromosome aberrations. 4) Treatment of Tfp for 36 hours after exposure to UV-light increased the sister chromatid exchanges UV-light. The aspects of increase were proportional to the concentration of Tfp. These data indicate that Tfp itself dose not induce chromosome aberrations and sister chromatid exchanges, but is concerned in chromosome aberrations and sister chromatid exchanges induced by UV-light; that is, it has the ability to decrease chromosomal aberrations but to increase sister chromatid exchanges. In conclusion, calmodulin has an effect on the damages and their recovery at the chromosome level, the induction pathways of chromosome aberrations and sister chromatid exchanges seems to be controlled by the different mechanisms.
