고진공내의 데칸용매하에서의 요오드화 iso-프로필의 용해도를 8, 15, 25℃에서 니트로벤젠과 톨루엔이 존재할 때와 존재하지 않을 때의 두 경우에 대하여 각각 측정하였다. 데칸용매내에 니트로벤젠과 톨루엔이 존재할 때 요오드화 iso-프로필의 용해도가 존재하지 않을 때 보다 더 크고, 톨루엔과 요오드화 iso-프로필과의 상호작용이 니트로벤젠과의 상호작용보다 더 강하게 작용한다는 것을 알 수 있었다. 그리고 니트로벤젠과 톨루엔이 데칸용매내에 존재할 때 요오드화 iso-프로필과 니트로벤젠 및 톨루엔이 각각 불안정한 Complex를 형성한다고 생각되어 이 Complex를 여러 경우의 비율로 가정하여 계산해 본 결과 1 : 1 Comples를 형성한다고 보는 경우의 평형상수 K값이 비교적 일정한 값을 나타내었다. 그러므로 1 : 1 Complex 즉 ??과 ??이 용매속에 형성됨을 알았다. 또한 이 Complex의 생성에 대한 엔탈피, 자유에너지 및 엔트로피의 변화도 산출하였다. The solubilities of iso-propyliodide in decane on high vacuum were measured at 8℃, 15℃ and 25℃ in the presence and absence of nitrobenzene and toluene. When nitrobenzene and toluene exist in system respectively, the solubilities of iso-propyliodide in the presence of nitrobenzene and toluene are greater than in the absence, and the interaction of iso-propyl iodide with toluene is stronger than with nitrobenzene. In the presence of nitrobenzene and toluene, it could be thought that iso-propyl iodide forms unstable complex with nitrobenzene and toluene. The complex was assumed in various ways and it was evaluated that the equilibrium constant K value was relatively constant under the assumption of 1 : 1 complex. Thus, 1 : 1 complexes, ??과 and ?? are formed in the solution. Also, the changes of enthalpy, free energy and entropy for the formation of the complex were calculated.

Objectives : We evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) in laparoscopic colectomy. Methods and Materials : Eighty patients who received laparoscopic colectomy were randomly divided into two groups: R group (ramosetron 0.1mg PO) and O group (ondansetron 4mg twice IV). Injection or oral medication was administered before the induction of anesthesia in each group. Injection was administered at the end of surgery in O group. General anesthesia was induced using propofol and rocuronium, and maintained with sevoflurane, remifentanil and air (FiO2 0.5), We investigated the incidences of PONV in each group by the Rhodes index of nausea, vomiting and retching (RINVR) at postoperative 6 and 24 hours. Results : The incidence of PONV was not different between group at each time points after surgery (at postoperative 6 hours: 20% in group R, 17.5% in group 0, at postoperative 24 hours; 12.5% in group R, 7.5% in group 0). There was no difference in the severity of PONV, satisfaction, rescue drug usage. Conclusion : Prophylactic therapy with ramosetron is as effective as conventional prophylactic therapy with ondansetron for preventing PONV in general anesthesia for laparoscopic colectomy.

We have investigated Pt and RuO₂as a bottom electrode for a device application of PZT thin film. The bottom electrodes were prepared by using an RF magnetron sputtering method. We studied some of the property influencing factors such as substrate temperature, gas flow ratem and RF power. An oxygen partial pressure from 0 to 50% was investigated. The results show that only Ru metal was grown without supplying any ‬O₂gas. Both Ru and RuO₂phases were formed for ‬O₂partial pressure between 10-40%. A pure RuO₂phasewas obtained with ‬O₂partial pressure of 50%. A substrate temperature from room temperature to 400°C was investigated with XRD for the film crystallinity examination. The substrate temperature influenced the surface morphology and the resistivity of Pt and RuO₂ as well as the film crystal structure. From the various considerations, we recommend the substrate temperature of 300°C for the bottom electrode growth. Because PZT film growth on top of bottom electrode requires a temperature process higher than 500°C, bottom electrode properties were investigated as a functiona of post anneal temperature. As post anneal temperature was increasedm the resistibity of Pt and RuO₂was decreased. However, almost no change was observed in resistibity for an anneal temperature higher than 700°C . From the studies on resistivity and surface morphology, we recommend a post anneal temperature less than 600°C.

Studies on the seasonal distribution of zooplankton were carried out in 1994 in waters off Yongkwang Atomic Power Plant. Zooplankton samples were collected four times seasonally at six selected stations. Forty - three taxa of zooplankton were distributed and 25 species representing 21 copepods, 2 chaetognaths, 1 protozoan and appendicularian were identified to species level. Zooplankton abundance varied between 840-42, 014 indiv. m-3 and were recorded the highest abundance in September and the lowest in February. Seasonal succession in the dominant species was observed from winter and spring with Acartia omorii to summer and autumn with A. pacifica and Paracalanus indicus. With the prevalence of ueritic copepods all the year round, i.e., A. omorii, A. pacifica and P. indicus, the studied waters were revealed to have the typical zooplankton fauna in coastal waters of the Yellow Sea.

A plane strain finite element model is developed to simulate turning with continuous chip formation using adaptive remeshing during the thermal-mechanical coupled analysis. Comparisons between the experimental and simulation results for cutting forces are performed to validate FE analysis results. Influences of machining parameters such as depth of cut, cutting speed and feed rate on cuting force and shear angle are analyzed by Taguchi method. The more depth of cut and feed rate result in the increase of cutting forces, but the rates of increase are decrease due to the larger shear angle. As the cutting speed increases, von Mises stress of workpiece near the tool tip decreases because the strength of specimen decreases at high temperature above 500℃. This thermal effect on cutting force is negligible because the affected area is very localized and the average values of von Mises stress in the shear plane are the same among the diverse cutting parameters.
