This study concerns the role of costume in Shakespearean tragedy from the viewpoint of the role theory. The term "role" has been used to represent the behavior expected of the occupant of a given position or status. A specific role can not be successfully performed without the aid of the Costumes. Costumes are adopted in relation with a specific role. The role of social status and position reflects sex, age, occupation, class, economic position of the characters. In his works, the crown and the mace represented not only the throne but also a previllege and supreme position. The sitution role of costume could be widely used for visualizing the psychological situation and external environments of the characters on the stage. The disguise role hided one's status, thereby makes possible acting others position. And the disguise role can bring about the change of status, age, sex, occupation, and atmosphere. The costume could be used as a voucher of love. The costume performed the role of the physical and psychic protection, and provided its wearer with consolation and peaceful mind. The costume reflected the custom of a society through its wearing condition and wearing configuration. The results obtained from this study can provide useful cues for understanding the role action in the social structure. This kind of understanding reveals the costume phenomena in real life, allows one to perform roles properly and efficiently, and opens our insight on the overall aspects of the costume culture.

Laser-arc hybrid welding has been considered as an effective pipe girth welding process since early 2000's. Tolerance for fit-up offsets such as gap and edge misalignment is one of most important requirements in pipe girth laser-arc hybrid welding, and several approaches using parameter optimization, a laser beam scanning and an arc oscillation have been tried. However the required offset tolerance has not been fully accomplished up to now and laser-arc hybrid welding has not been widely applied in pipeline construction than expected, despite of its high welding speed and deep penetration. In this study, internal welding was adopted to ensure the offset tolerance and sound back bead. The effect of welding parameters on bead shape was investigated at the flat position. Also tolerances for gap and edge misalignment were verified as 0.5 mm and 2.0 mm, respectively. The position welding trials were conducted at several welding positions from the flat to the overhead position in a downward direction. With the fixed welding speed, arc current for gas metal arc welding current and laser output power, adequate welding voltages for gas metal arc welding were suggested for each position.

Patients who had claustrophobia tend to feel fear when they were scanned by an MRI, CT, PET-CT, or using a gamma camera scan. In this paper, claustrophobic patients were tested to find effective ways by changing patient's positions. For this paper, PET-CT scan in patients who had claustrophobia were used in the prone position. Prone position helped to maintain stable position and to get a h0igh quality of inspection without failure. Thus, as claustrophobic patients were requested taking prone position, they could feel comfortable. In a confined space, prone position for the claustrophobic patients who had a fear of the PET-CT examination would be expected to reduce the failure rate of inspection.

The difference between definition time of GPS (Global Positioning System) position data and actual display time of car positions on a map could reduce the accuracy of car positions displayed in PND (Portable Navigation Device)-type CNS (Car Navigation System). Due to the time difference, the position of the car displayed on the map is not its current position, so an improved method to fix these problems is required. It is expected that a method that uses predicted future positionsto compensate for the delay caused by processing and display of the received GPS signals could mitigate these problems. Therefore, in this study an analysis was conducted to correct late processing problems of map positions by mapmatching using a Kalman filter with only GPS position data and a RRF (Road Reduction Filter) technique in a light-weight CNS. The effects on routing services are examined by analyzing differences that are decomposed into along and across the road elements relative to the direction of advancing car. The results indicate that it is possible to improve the positional accuracy in the along-the-road direction of a light-weight CNS device that uses only GPS position data, by applying a Kalman filter and RRF.

Purpose: This study attempted to test whether there are differences in the level and hemodynamic side effects (blood pressure, heart rate, $O_2$ saturation), and nausea & vomiting of spinal anesthesia using hyperbaric bupivacaine according to position (supine, lateral, and prone positions) in orthopedic surgery patients who received podiatric surgery under spinal anesthesia. Methods: This study was conducted with 53 patients who had received orthopedic surgery under spinal anesthesia at I General Hospital. Data were analyzed using SPSS 20.0 through repeated-measures ANOVA, post-hoc test, Chi-test, and Fisher's exact test. Results: The change of position after spinal anesthesia with hyperbaric bupivacaine caused a change in the level of spinal anesthesia (F=12.768, p<.001). However, no difference of blood pressure, heart rate, $O_2$ saturation and nausea and vomiting caused by the change in anesthesia level was observed, and in prone position, drug was administered for the correction of side effects. Conclusion: As expected, recognizing that there can be a change in the level of spinal anesthesia after the change of position in surgical patients, nurse anesthetists should monitor their conditions carefully and continuously.

Aerostatic planar XY stages are frequently used as the main frames of precision positioning systems. The machining and assembly process of the rails and bed of the stage is one of first processes performed when the system is built. When the system is complete, the 2D position, motion, and stage flatness errors are measured in tests. If the stage errors exceed the application requirements, the stage must be remachined and the assembly process must be repeated. This is difficult and time-consuming work. In this paper, a method for estimating the errors of a planar XY stage is proposed that can be applied when the rails and bed of the stage are evaluated. Profile measurements, estimates of the motion error, and 2D position estimation models were considered. A comparison of experimental results and our estimates indicated that the estimated errors were within $1{\mu}m$ of their true values. Thus, the proposed estimation method for 2D position and flatness errors of an aerostatic planar XY stage is expected to be a useful tool during the assembly process of guideways.

For telecommunication system construction to minimize the casualty of fisher, we investigated the usability of TRS communication system and performance of GPS automatic position transmitter (APT) which can be utilized for the survival, search and rescue of the victims. The trial experiments were conducted at sea with TRS and CDMA in the East, West and South Sea of Korea from October to December. As a result, the usability of the TRS as an emergency communication system device was verified since it provided stable position and voice information to the boundary of 50km far from the coast. Therefore the system is expected to contribute to minimization of victims.

Objective of calibration is to find out the accurate kinematic relationships between robot joint angles and the position of the end-effector by estimating accurate model parameters defining the kinematic function. Estimating the model parameters requires measurement of the end-effector position at a number of different robot configurations. This paper studies the implication of measurement configurations in robot calibration. For selecting appropriate measurement configurations in robot calibration, an index is defined to measure the observability of the model parameters with respect to a set of robot configurations. It is found that, as the observability index of the selected measurement configurations increase the attribution of the position errors to the parameter errors becomes dominant while the effects of the measurement and unmodeled errors are less significant; consequently better estimation of parameter errors is expected. To demonstrate the implication of the observability measure in robot calibration, computer simulations are performed and their results are discussed.

Selective COX-2 inhibitors were expected to retain anti-inflammatory activity by inhibition of prostaglandin production with reduction of gastric and renal side effect associated with non-steroidal anti-inflammatory drugs. This study reported the syntheses of novel 2-thiohydantoin and hydantoin derivatives which have the structure of 5-membered heterocyclic ring substituted with two aryl groups, phenyl group at 5-position and p-sulfamylphenyl or p-methoxyphenyl group at 1-position. These synthetic compounds showed significant COX-2 activities in vitro screening. Among them, 5-phenyl-2-thiohydantoin and hydantoin substituted with benzyl group at 3-position, compounds 5 and 8, could be considered as lead compounds with $IC_{50}$/=13.13∼18.78 $\mu\textrm{g}$/$m\ell$ for the development of COX-2 inhibitors.
