The effects of muscle relaxants(vecuronium, pancuronium, d-tubocurarine, and succinylcholine) for endotracheal intubation on intraocular pressure, blood pressure, heart rate, and arrhythmia were studied in 60 patients undergoing general anesthesia, The patients were divided into 4 groups : vecuronium group (0. 1 mg/kg), pancuronium group (0.08 mg/kg), d-tubocurarine group(0.4 mg/kg), and succinylcholine group(1 mg/kg) according to be administrated. Before induction of anesthesia, initial measurement of intraocular pressure (control value) was taken with Schiotz tonometer after instilling of a 0. 5% pontocaine on conjunctival sac. Subsequent measurement were undertaken as soon as the lid reflex was lost after thiopental sodium injection and then at 75-100% depression of first twitch height of train-of-four after intravenous administration of muscle relaxants. It was measured at 1, 3, 5, 10 minutes after endotracheal intubation too. Blood pressure (systolic and diastolic), heart rate, and ECG abnormalities were observed in all cases. The results were as follows; 1. After thiopental sodium injection, intraocular pressure(IOP) decreased than the control value. 2. At 70-100% depression of first twitch height, IOP decreaeed significantly in vecuronium, pancuronium and d-tubocurarine group, but increased significantly in succinylcholine group than the control value. 3. After 1 minute of endotracheal intubation, IOP increased in all groups. There was no stastistical significance in vecuronium group compared with the control value. 4. After 3 minutes of endotracheal intubation, IOP decreased in all groups. 5. The changes of systolic and diastolic blood pressure and heart rate in vecuronium group were the smallest value among all groups. 6. There was no arrythmia in vecurouium group.

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

The capability to map all potrions of the earth's surface always depended on the capacity to survey. Classical analog photogrammetry has been enhanced by more accurate and more rapid digital vector output. Analog plotter can moreover now easily be converted into analytical instruments to facilitate orientation, operator asisted DTM measurement, aerial triangulation, and vector plotting. Digital photogrammetry with scanned aerial photography has greatly enhanced the capabilities of restitution at large and medium scales. Digital orthophotography offers possibilities, which are one order of magnnitude less costly than conventional mapping, even though the same resolution performance cannot yet be reached, when digital work stations with reasonable computing speeds are campared with analytical plotters. However with rapidly increasing computer performance, the situation is gradually changing in favour of digital systems. In this study, the accuracy of three dimensional location was improved by bundle block adjustment with additional parameters, which are able to systematic error through detection and elimination of the gross error for observation values in aerial triangulation. In order to test thevariability in performance of the different weighting schemes in accurately detecting gross error, robust estimation method. And also, the different control point patterns and ovelap, twelve types of additional parameters were used for comparison analysis. As a result, it is expected to the sequential procedure of analysis can be utilized in the accuracy analysis of aerial triangulation effectively.

Computer Mapping System(CMS) are being used in various government offices as well as coporates as a tool in decision making. Efforts are being made to implement computer mapping system databases to systematically and effectively carry out planning, management and monitoring in various fields. But the present dituation is that the database design itself is a big job since the methodology of planning and design of mapping systems are still being studied. This study is about the base conception of Land Information Management, which is an important and time consuming activity necessary in the implementation of such systems. The study was then applied to highway, environment, map management where the functions and data used in highway, environment, map management system were identified through system analysis and the computer mapping system database was designed based on this analysis. Also appplication systems were developed to support departments which used various maps and drawings. Conclusively, the techniques introduced in this study could serve as a useful tool not only in buiding more specific land evaluation system but also in collecting data necessary for Land Information Management System.

The use of digital terrain model has been enlarged in calculation of earthwork plays a major rule in plan or design of many civil engineering projects, and thus it has become very important to advance the accuracy of earthwork calculation. The earthwork volume,an important factor in the field of civil engineering,could be counted with the computerized by the use of simpson's 1/3 and 3/8 rules. The thesis is the earthwork volume could be counted by the measurement of HAEUN-DAE-GU topograph data.

위성측지측량을 위한 GPS 신속 관측기법의 활용에 관한 연구

이동락,박운용,신상철 東亞大學校 大學院 1995 大學院論文集 Vol.20 No.-

The NAVSTAR GPS(NAVigation System with Time and Ranging Global Positioning System)is a satellite-based radio navigation system providing precise three-dimensional position, navigation, and time information to suitably equipped users. The system will be continuously avilable on a world-wide basis, and is independent of meteorological conditions. The Global Positioning System was primarily designed for military navigation system by the US Department of Defense(DoD) in 1973. It has been successfully used in civilian geodetic surveying since 1983. Thereafter, it has been proved that GPS is the most valuable and excellent method, that ever exist in positionong system. Previous application of GPS was mainly based on the time-consuming static measurement which is combined with the results of existing triangulation or trilaterlation. Presently, however, new rapid methods are developed by using the experience of static method. These satisfy the most advantage of GPS in aspect of rapidity, accuracy and economy. In the relative kinematic methods, one antenna is always fixed at reference station and the other one travels sequentially to measuring points. Although rapid measurement method takes a few seconds or minutes, it cope with the accuracy of static method. In this paper, the characteristics of new methods are presented. Also many experiences are discussed about the coastal GPS experiment where the Kinematic Differential GPS is needed to detect the morphologic changes.
