Purpose: This study examined two trunk strategies - medio-lateral ramp and anterior-posterior ram - and their effects on pelvis and trunk movements, providing basic material for safe ramp utilization. Methods: The present study included 20 asymptomatic males recruited from a local university. Participants were asked to stand with their feet shoulder-width apart. Their dorsal side faced the camera, and measurements were performed while standing in a neutral double stance, one leg stance, $15^{\circ}$ of medial and lateral ramp, and $15^{\circ}$ of anterior and posterior ramp. Participants were allowed to practice for 3 minutes, and each participant had a 30 seconds rest between the two ramp conditions. One-way repeated measures analysis of variance was used to determine the effects the ramp conditions on spinal alignment. In all analyses, p<0.05 was used to indicate statistical significance. Results: The trunk-inclination angle on the posterior ramp was significantly lower than that of the double stance position (p<0.05). The trunk imbalance angle was significantly higher on the medial ramp, than that on the double stance position (p<0.05). The pelvic position and pelvic torsion angles were significantly higher in the medial, lateral, and anterior ramp positions than that of the double stance position (p<0.05). The pelvic rotation angles on the medial, lateral, and anterior ramps were significantly lower than that of the double stance position (p<0.05). Conclusion: These findings suggest that when people are exposed to the same form of ramp for an extended period, posture modifications may be triggered.

This study was undertaken to investigate the effect of exercise induced pulmonary hemorrhage(EIPH) on the finishing position of racehorses, 400 bleeders(305: 1 time, 76: 2 times, 19: 3 times, total: 514 cases) which had bled(EIPH) from their nostrils after their races at the Seoul racecourse during the 5 years period('93-'97) were analyzed for this study. The ratio of bleeders to total racehorses in finishing position 1-3,4-6, 7-9 or above 10 was 0.55, 0.84, 0.90 or 1.13%, respectively. There is tendency to higher incidence of bleeding in the later positioned racehorses group. To analyze the correlation between EIPH and finishing position, finishing potion of each EIPHed horses' was checked at 7 successive races(3 races each before/after EIPH. The average final position at the -3rd race, -2nd racer -lst racer EIPHed race, 1st race,2nd race and 3rd race of each bleeder was 5.85. 5.94, 6.21, 7.32, 7.20, 6.51 and 6.53, respectively. Raring times were adjusted to 1,000 m equivalent. Average racing times of the -3rd race,-2nd racer -lst raced EIPHed race, 1st race, 2nd race and 3rd race of each bleeder was 67.1, 67.1, 67.2, 67.6, 67.5, 67.4 and 67.3 second, respectively. Bleeders which finished the race within 1 second following the winners were 25. 3% of total bleeders. The rest 74.7% reached at the finish line 1 second later than the winners. Particularly 46.3% of bleeders were above 2 second later. Therefore this study suggested that bleeding has effect on performance of the racehorse, consequently it make bleeders be placed later positions.

Purpose: The purpose of this study was to examine the effect of position change on discomfort and bleeding in patients undergone coronary angiography with a vascular device and required bed-rest. Method: This study utilized nonequivalent control group non-synchronized design. Data were collected from 118 inpatients after coronary angiography and stayed in general ward at Y hospital in Seoul, from June 5 to August 12, 2008. After coronary angiography, position change was performed to the experimental group who consisted of 59 patients. They stayed in supine position just after angiography and then head-up position with 15 degrees was applied 1 hour later. After that, they could change the position alternatively into lateral position with leg down and supine position. The control group was positioned keeping the affected leg immobile with supine position for 4 hours. Results: The experimental group reported significantly more comfortable than control group after position change. There were no significant differences in the grades of bleeding or hematoma at puncture site between the two groups. Conclusion: The position change in patients undergone angiography could be applied without any harm such as bleeding or hematoma, but effective in reducing back pain and subjective patients' discomforts.

This study was performed to investigate the effects of occlusal appliance on the mandibular position and the mandibular rotational torque movement during speech. For this study, 20 patients with temporomandibular disorders(TMDs) and 20 normal subjects without any signs and symptoms in the masticatory system were selected as the patient group and as the normal group, respectively. Biopak $system^{(R)}$(Bioresearch Inc., Milwaukee, USA) and a sentence of 'Sue is missing her house' were used for recording and for observing of speech pattern. There were five mandibular positions observed in this study, that is, mandibular rest position, 'ssi', 'her', 'ha', and 's' speech position. In each position, slant and A-P distance in sagittal plane, vertical distance and lateral distance in frontal plane were measured. Amount of the mandibular rotational torque movement were measured at 'her', 'ha' speech position and for all through speech movement. Centric relation splint(CRS) was placed in both groups, but anterior or posterior bite plane were placed in normal subjects only. Data collected were processed and analysed by SPSS windows program. The results of this study were as follows : 1. Mandibular positions in both groups were not different before adaptation, with CRS, and after removal, but total amount of the mandibular rotational torque movement was greater in patients. 2. Mandible was slightly placed anteriorly with CRS at 'her' and 'ha' speech position in patients, but was placed anteriorly at all the five positions in normal subjects. 3. Difference with type of occlusal appliance in normal subjects were noted only for vertical distance at 'ssi' and 'ha' speech position, and the distance with CRS were more than that with posterior bite plane. 4. Mandibular rotational torque movement at 'her' and 'ha' speech position was greater in patients, but the difference was disappeared after appliance removal. And the torque movement was greater at 'ha' speech position than that at 'her' speech position in frontal plane. It could be concluded that the adaptation of occlusal appliance showed a tendency to locate the mandible anteriorly during speech in both groups, but did not affect total mandibular rotational torque movement which was greater in patients.

The prosthodontic treatment of Class II division 2 malocclusions is challenging. Ideally, these malocclusions should be identified at an early age and corrected with orthodontic treatment; otherwise, the individual develops a habitual position characterized by deep overbite and significant retruded position of mandibular condyle at the TMjoint fossa. This article describes a clinical protocol for the occlusal rehabilitation of patients with Class II div.2 malocclusions. Within this protocol, an occlusal splint was used to locate the most suitable maxillary-mandibular relationship for function and range of motion. The splint increased the vertical dimension and reduced pain on TMjoints. After transfer this relationship to an articulator for fabrication of provisional restorations, the CR position and centric prematurity contact between maxilla and mandible was used to determine the tentative vertical dimension of occlusion(VDO). The amount of elevation of VDO was decided on the articulated model. The provisional restorations were accurately transfered to a patient's mouth in clinical procedures using tattoo points. The final restoration was delivered after some trial periods with provisional restorations. The theory behind this protocol and its associated clinical procedures is presented along with a discussion.

The aim of this study is to compare measurements of abdominal muscle thickness using ultrasonography imaging (USI) to those using a special transducer head device, during five different trunk stabilization exercises, ultimately to determine which exercise led to the greatest muscle thickness. Thirty eight healthy subjects participated in this cross-sectional study. The five types of trunk stabilization - i.e., a sit-up on the supine, an upper and lower extremity raise with quadruped on the prone, a leg raise in sitting on the ball, trunk rolling on the ball, and balance using sling on the prone position - were each performed with an abdominal draw. The thickness of the abdominal muscle - including the transverse abdominal (TrA), internal oblique (IO), and external oblique (EO) - was measured by USI with a special transducer head device, at rest and then at contraction in each position. Data were analyzed using one-way repeated ANOVA with the level of significance set at ${\alpha}$=.05. The results were as follows: 1) the TrA thickness was statistically significant (p<.05), whereas the IO and EO thicknesses were not (p>.05); 2) among the five types of trunk stabilization, TrA thickness significantly increased with the balance using a sling in the prone position, (p<.05), whereas no significant difference was noted for the four types of trunk stabilization (p>.05); 3) reliability data showed that there was a high degree of consistency among the measurements taken using the special transducer head device (ICC=.92). In conclusion, the balance using a sling in the prone position was more effective than any of the four other types of trunk stabilization in increasing TrA thickness in healthy subjects.

The purpose of this study was to evaluate and compare the effectiveness of ilioinguinal-hypogastric nerve blocks(IHNB) and caudal block in producing post-orchiopexy and post-heniorrhaphy analgesia in children. Forty consenting healthy children, ages 3~10yr, were randomly assigned to receive caudal bupitvacaine (0.125%, 0.5ml/kg), or IHNB bupivacaine (0.25%, 0.3 ml/kg). Blocks were performed following the induction of general anesthesia, be fore the operation. Pre-anesthetic medication in form of atropine 0.01 mg/kg, droperidol 0.05 mg/kg were given intramuscularly one hour before induction to 40 children. Children were induced with thiopental sodium 5 mg/kg and succinylcholine 1 mg/kg intravenously. Anesthesia was maintained with oxygen-nitrous oxide ($FiO_2$ 0.3) and ethrane. When the patients stabilized after induction. IHNB was done in the supine position and caudal block was done in the lateral position. The local anaesthetic was injected after negative aspiration. Postoperative pain was assessed with face pain rating scale (RPRS) at rest on discharge of recovery room, and 5 hours after discharge of recovery room, and the "red and white" visual analogue scale (VAS) at rest and mobilization from supine to sitting position on discharge of recovery room, and 5 hours after discharge of recovery room. Post-operative recovery was quiet and comfortable, without side effect. Relief of ain was complete in both IHNB group and caudal group. Surgeons, parents and recovery room personnel were satisfied. There were no surgical or anesthetic complications. In our study, the postpoerative pain scores were similar in both IHNB group and caudal group. IN conclusion, we found that both IHNB and caudal blocks before the start of surgery for orchiopexy & herniorrhaphy are safe and effective in controlling the postoperative pain of children.

The purpose of this study was to provide basic data necessary for improvement by closely examining factors of having influence upon dental technicians' turnover. Questionnaire survey was conducted of 204 dental technicians who work at dental hospitals, clinics and dental laboratory rooms in Daegu area. The following conclusions were obtained. The satisfaction with job was high in job position in more than co-representative, in the whole and other task, and in less than 9 hours as for working hours. In the satisfaction with working environment, dissatisfaction was high in women, in the working career with 7~9 years, in chief level as for the job position in charge, in being responsible for porcelain in case of the duty field, and in more than 10 people as for the number of employees. The higher satisfaction with job satisfaction and working environment led to the lower turnover intention. Turnover intention was low in case of having ventilation fan & dust collector desk and in case of being well ventilated inside the workshop. As the above results, it is considered to be necessary for arranging institutional device of protecting dental technicians' health and reducing turnover through improving working environment such as forming comfortable environment of using the dust-collecting facilities and the ventilation facilities, wearing suitable individual protective gear and arranging the rest space.
