In this paper, we introduce certain concepts which we will provide us with a perspective and insight into the problem of calculating best approximations. The material of this paper will be mainly, but not only, used in developing algorithms for the one-sided and two-sided sided approximation problem.

鑒於性理學傳入韓國的時期, 有學者主張是北宋時期, 也有部分學者對此持否定意見, 指出是南宋時期經由高麗末期的安珦傳入韓國.筆者認爲與其說是某一時期由特定人物將性理學'導入'韓國, 不如說是時代潮流下諸多人士關心與努力的結果, 這一自然而然的'流入'說更爲妥當.本文以此爲前提, 指出止浦金坵正是奠定性理學'流入'礎石的代表性人物, 並對此加以論證. 本文首先考察了止浦金坵初赴大都時中國的儒學即性理學的具體展開情況, 其次對元朝儒臣王鶚這一人物進行了了解, 不管是采取何種方式, 總之王鶚與止浦之間有著交流, 論文對其在學問上直接或間接影響止浦的可能性進行了判斷. 通過以上的考察與辨析.

Background: Usually, lumbar epidural block is performed on the $L_{3-4}$ interspace. This study was designed to evaluate the analgesic efficacy and shortening of labor duration comparing the $L_{1-2}$ and $L_{3-4}$ interspace epidural blocks in nulliparous normal vaginal deliveries and then investigates side effects following the blocks. Methods: Eighty healthy nulliparous women were divided into two groups, $L_{1-2}$ (n = 40) and $L_{3-4}$ (n = 40). Epidural blocks, lumbar epidural block were performed at the $L_{1-2}$ and $L_{3-4}$ interspace with a catheter advancing 3 cm cephalad. The initial dose of 12 ml (0.167% bupivacaine, fentanyl $50{\mu}g$ and clonidine $75{\mu}g$) was injected epidurally at 4 cm dilatation of cervix and severe pain of labor. If a visual analogue scale (VAS) score was more than 4 points, an additional dose was administered epidurally using the same volume as the above mentioned, but with the exception that the bupivacaine was diluted to 0.1 percentage. The maternal blood pressure, pulse rate, respiration rate and fetal heart rate were measured at 10 min intervals for the first 30 min, at 15 min interval for the next 30 min and at 30 min interval for the last one hour following the blocks. The duration of the first (active) and second stages of labor was counted and the neonatal Apgar score was recorded at one and five min after delivery. The degree of motor block, pruritus, nausea and vomiting were also noted. Results: The patients in group $L_{1-2}$ had lower pain scores than group $L_{3-4}$ at 5, 20, 30, 60 mins. The duration of 1st and 2nd labor stage in the $L_{3-4}$ epidural block were $272{\pm}33.5$ min, $49.2{\pm}27.4$ min respectively but those in the $L_{1-2}$ epidural block were $253.5{\pm}32.5$ min, $37.3{\pm}22.3$ min, respectively. Conclusions: We concluded the analgesic efficacy and shortening of labor duration in $L_{1-2}$ epidural block was better than those in $L_{3-4}$ epidural block. Maternal hemodynamic change, motor block. pruritus, nausea, vomiting and Apgar score showed no significant differences between the two groups.

The development of severe pericardial adhesion after cardiovascular surgical procedures often increases the risk of injuring the heart, great vessels, or extracardiac grafts during resternotomy. Several pericardial substitutes have been tested in an attempt to facilitate reoperation with inconclusive results. This study was designed to evaluate the applicability of two different materials as pericardial substitutes to minimize the pericardial adhesion and epicardial reaction. A procedure for induction of pericardial adhesion was carried out in 30 rabbits. Rabbits were divided into three groups of ten rabbits each: Group 1[control, simple pericardial closure]: Group 2[bovine pericardium as pericardial substitute]: Group 3[e-polytetrafluoroethylene surgical membrane, e-PTFE as a pericardial substitute]. Bovine pericardium or e-PTFE surgical membrane was interposed between the sternum and the heart. Rabbits were sacrificed at 4 weeks after operation. The development of adhesions and epicardial reactions were graded as: none [I]; minimal[II]; moderate[Ill]; and severe[1V]. Histologic studies of the substitute, the pericardium, and the epicardium were performed. The results were as follows; l. In group 1[control group], the degree of pericardial adhesions were grade I in none, grade II in 1, grade III in 3, and grade 1V in 6 animals. Epicardial reactions were grade I in none, grade II in 3, grade K in 4, grade 1V in 3 animals respectively. 2. In group 2[bovine pericardium], the degree of pericardial adhesions were grade I in 1, grade II in 5, grade III in 3, and grade 1V in 1 animal. Epicardial reactions were grade I in 1, grade II in 2, grade III in 4, and grade 1V in 3 animals respectively. 3. In group 3[e-PTFE], the degree of pericardial adhesions were grade I in 7 animals, grade II in 2, grade III in 1, and grade g in none. Epicardial reactions were grade I in 4, grade II in 3, grade III in 2, and grade IV in 1 animal respectively. Pericardial adhesions more than grade II were 90.9% in group 1, 40 % in group 2, and 10% in group 3. Pericardial adhesions were significantly reduced in group 3 compared to group 1 or 2. Epicardial reactions more than grade II were 70 % in group 1, 70 % in group 2 and 30 % in group 3. We concluded that this 0.1mm thick polytetrafluoroethylene surgical membrane is a suitable pericardial substitute to minimize the development of pericardial adhesion or epicardial reaction following cardiovascular surgery.

Current physics-based simulation is an important tool in the fluid animation. However some problems require a new change to current research trends which depend only on the simulation. The ultimate goal of this project is to obtain information of flow example, analyze an example through machine learning and the novel fluid animation reconfigure without physical simulation.

In this paper we derive an integral formula on an (n + 1)-dimensional, compact, minimal contact CR-submanifold M of (n - 1) contact CR-dimension immersed in a unit (2m+1)-sphere $S^{2m+1}$. Using this integral formula, we give a sufficient condition concerning with the scalar curvature of M in order that such a submanifold M is to be a generalized Clifford torus.
