The very few non-contact method are still in the early stage. One of the non-contact methods is by the use of the laser that has high-level of the accuracy for the measurement, and this laser also has excellent characteristics on which many studies for its applications are focused throughout the many fields. The dissertation is on the measurement of the strain caused by the characteristics of the spot welded zone which is used with 3-D ESPI system that is functionally modified through the laser ESPI(Electronic Speckle Pattern Interferometry) system. This system employed the SGCC 1.2t which are mainly used for the steel plate such as automobile, structure, electronics instrument, building material and electronic appliances.

It has been observed that assured service in the differentiated service network cannot guarantee the contracted profile rate fairly. Achieved throughput depends on the profile rates. TCP's congestion avoidance algrorithm causes this. In this paper we proposed 3-drop precedence scheme which is using token bucket and TSW(Time Sliding Window) marker to solve this problem. we showed proposed scheme improves the performance of assured service and this scheme is effective also when the non-responsive UDP traffic sources exist.

生後 1개월령부터 8개월령 까지의 在來山羊 수컷 38두의 發育 및 屠體調査를 하였다. 生體重은 1개월령에 4.2kg이었고, 8개월령에는 14.5kg이었다. 屠體率은 37.2∼43.4%였으며, 頭重率은 4개월령 이후에 有意的으로 감소했으며, 生體重에 대한 第一胃容積의 比는 6개월령 까지 증가한 후 점차 감소되었다. 7∼8개월령, 山羊 10頭의 精肉率은 29.8%이었으며 兩側 背長筋 斷面績은 7.92㎠이었다. 屠體重, 頭重 및 第一胃容積과 生體重 間에는 高度의 有意的인 正相關이 있었다. The body growth and some carcass data of 38 male Korean native goats from 1 to 8 months of age have been studied. The body weight increased from 4.2kg at 1 month of 14.5kg at 8 months of age. The dressing % ranged from 37.2 to 43.4%. The head % decreased significantly(P<0.05) after 4 months of age. The rumen capacity per kg body weight increased significantly (P<0.05) to 6 moths of age and decreased thereafter. The lean % and loin-eye muscle area of both sides in goats from 7 to 8 months of age averaged 29.8% and 7.92㎠, respectively. There was a significant (P<0.01) correlation between body weight and carcass weight, head weight or rumen capacity.
위 유문동근 K^+ - 경축에 미치는 Vanadate의 효과
김충수,고인송,엄대용,이상돈 중앙대학교 의과대학 의과학연구소 1988 中央醫大誌 Vol.13 No.3
Effects of vanadate on the spontaneous contraction and the high K^+-induced contracture of guinea pig’s pyloric antral smooth muscles were observed in the various Na^+ and/or Ca^+ of bathing solutions. Following results were obtained; 1. Basal tension and developed tension of the spontaneous activity were increased by vanadate and the membrane potential tended to be depolarized. 2. Phasic contracture increased, tonic contracture decreased as the outside K^+ concentration increased and the both components were increased by vanadate. 3. In the case of absence of K^+ and/or Na^+, the contracture were hardly developed and the spontaneous, rhythmic contraction were sustained. 4. Effects of vanadate on the K^+-contracture and the Ca^2+-sensitivity of the Phasit and tonic components were prominent in the presence of Na^+. The above results suggested that vanadate would increase the voltage-dependent calcium current in smooth muscle cells of the pyloric antrum.
기본 항암 화학요법에 불응 하는 전이성 이행상피 세포암 환자에서 시행한 증량 M-VAC 항암 화학 요법 2례

1. 목적 전이성 방광 이행 상피 세포암의 경우에 시행될 수 있는 몇가지 전신적 항암 요법 중 M-VAC 병용 투여가 가장 인정받고 있는 항암 요법이긴 하나 일시적 반응 후 재발시 즉 M-VAC 병용투여에 불응하는 경우 증상 완화 요법(palliative therapy) 이외에 다른 치료 방법이 없었다. 저자들은 M-VAC 병용 요법에 불응하는 전이성 방광 이행상피 세포암 환자 2례에서 기존 M-VAC 항암 화학 요법보다 항암제 투여량을 증량한 M-VAC 항암 요법을 시행하였다. 2. 방법 기존 M-VAC 항암 화학요법용량(Methotrexate 30㎎/㎡, Vinblastine 3㎎/㎡, Adriamysin 30㎎/㎡, Cisplatin 70㎎/㎡)보다 항암제 용량을 증량하고(Methotrexate 30㎎/㎡, Vinblastine 4㎎/㎡, Adriamycin 60㎎/㎡, Cisplatin 100㎎/㎡) 이로 인한 골수 저하증을 예방하기 위하여 GM-CSF를 동시에 투여하였다. 3. 결과 증례 1 환자는 중량 항암 화학 요법 1개월 후 추적검사에서 전이된 임파절이 모두 소실된 완전 관해를 보였으며 증례 2 환자는 증량 항암 요법 후 14일째 폐혈증으로 사망하였다. 4. 결론 증량 M-VAC 항암 화학 요법은 아직 시행 기간 및 증례가 많지 않아 완전 관해 기간 및 적절한 항암요법 시행 횟수의 미확립, 항암제 치료 도중의 치사율의 감소등이 문제점으로 지적되고 있으나 기존 M-VAC 항암 요법에 불응하는 전이성 방광이행 상피 세포암 환자에서 우선 고려될 수 있는 치료법으로 사료된다. Background : M-VAC(methotrexate, vinblastine. doxorclbicin, cisplatin) chemotherapy is the most common and effective treatment modality for advanced transitional bladder tumor. However, there is no effective therapy in case of the patients nith bladder tumor refractory to M-VAC chemotherapy. Methods : Two male patients mith metastatic transitional bladder tumors refractory to conventional chemotherapy with methbtrexate, vinblastine, doxorubicim, and cispiatin (M-VAC) were treated with escalate3 dose of M-VAC plus recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF). Formula of escalated M-VAC chemotherapy were 30mg/m^(2) of inethotrexate, 4mg/m^(2) of vinblastine. 60rmg/m^(2) of doxorubicm, and 10Omg/m^(2) of cisplatin, and 250mg/m^(2) rhGM-CSF per day administered subcutaneously (SC) for 10 consecutive days. Result : One of the treated patients mas responded with complete remission and the other one m-as dead by sepsis on post-escalated M-VAC chenctherapy 14 days. Coclusion : We believe escalated M-VAC chemotherapy may be one of the effective alternative treatment for patients with metastatic urothelial tumor refractory to conventional M-VAC chemotherapy.

The crystal structure of potassium chloride and potassium bromide have been determined by X-ray diffraction method. Both unit cells are face-centered cubic, F(4/m)3 ̄(2/m) z=4 but a=5.2857Å, V=248,348Å^3, D_c=1.989 gr/㎤ for KCl and a=6.5891Å, V=286.074Å^3, D_c=2.756 gr/㎤ for KBr. the structures were solved by graphical method using thirteen KCl and eleven KBr powder diffractometer data. The agreement between the experimental and theoretical integrated intensities of the reflecting planes is fairly good. The crystal are aggregates of positive and negative ionic atoms. Each atom has six nearest neighbors of the other kind. The distances between unlike atoms are 3.1429Å in KCl and 3.2945Å in KBr.
