The purpose of this study is to use standard and downward slope of the keyboards with taping to influence electromyography of upper trapezius. The effect of taping raise a medical criticism, but we do an experiment on two kind of keyboards with taping in order to decrease stress of shoulder. Subjects are in Seonam university whose are twelve healthy adults in their twenties. This experiment used two kind of keyboards. Standard keyboard's degree is $0^{\circ}$ and another keyboard's degree is $-7.5^{\circ}$. Application of Kinesio taping attached belly of upper trapezius tightly. Measurement of electromyography attached posterior of acromion process go by spinous process of 7th cervical vertebra and upper trapezius. Method of analysis used Repeated measure two-way ANOVA. Result of this experiment, both shoulder's muscle activity increased(p<.05) when used standard keyboard and downward keyboard with taping used. We compared muscle activity that used downward keyboard than standard keyboard. Statistically, it dosen't increase in neck and shoulder(p>.05). Therefore, using a keyboard with upper trapezius's taping in order to decrease muscle activity isn't influenced.

The vertical structure of atmosphere was observed In investigate the variation of surface ozone concentration by vertical downward mixing of residual ozone in the atmospheric boundary layer at the Busan coastal area. Airsonde and pilot balloon measurements were made at Gamcheondong and the Kimhae airport for April 26~27, 1996. The vertical potential of potential temperature showed a residual layer between 510m and 1800m from 2100LST April 26 to 0900LST April 27. The downward mixing of ozone in the residual layer of the atmospheric boundary layer was confirmed from vertical profile of mixing ratio near 600m in the morning. The thickness of the sea breeze layer was 900m at 1500LST April 26. Thereafter, it become to be lowered with time A low level jet was measured near 900m at 0300LST on April 27 from a pibal measurement. Early morning sharp increase of surface ozone concentration at the Busan coastal area was caused by vertical downward mixing of ozone concentration rather than by photochemical reaction In the atmospheric boundary layer.

Purpose : To determine the head position that the superior border of the mandibular canal as well as mental foramen can be more clearly visualized in panoramic radiography Materials and Methods : Ten dry mandibles were radiographed bilaterally using PM 2002 CC panoramic machine. A 20 mm thick aluminium filter was added to the slit collimator to obtain radiographs with acceptable density. The specimens were tilted by 2, 4, 6, 8, and 10 degrees downward with and without radiopaque markers. Radiopaque markers were inserted into the mandibular canals and the mental canals of each side of the specimens to serve as reference image when assessing the radiographs. The visibility of the mandibular canal and the mental foramen was estimated by 4 observers on all radiographs. The obtained results were analyzed statistically. Results: Mandibular canals were significantly more clearly visible in the radiographs with 4 and 6 degree downward position on both sides (P<0.05). Mental foramens were significantly more clearly visible in the radiographs with 4, 6, and 8 degree downward on right side and 6 degree downward on left side (P<0.05). There was not significant difference between right and left sides. Conclusion: Panoramic radiographs with 4 to 6 degree downward tilting could be valuable in locating the mandibular canal as well as the mental foramen.

The purpose of this report is to review vertical dysplasia such as openbite or deep bite in skeletal Class III malocclusion and their treatment modality and to present two cases treated with MEAW. The results obtained were as follows A. Open bite case 1. The treatment time was 3 year 8 months. 2. Upper and lower incisors showed extrusion and especially lower anterior alveolar process showed remodelling. 3. The mesially inclined upper and lower molars were uprighted and especially lower first molars showed extrusion that means remodelling of alveolar bone. 4. Normal overbite and overjet were established. 5. Mandible showed slight clockwise rotation. 6. Maxilla showed slight downward bending of ANS part. 7. Upper lip showed downward drop and lower lip showed retraction and touch between upper and lower lip was established. 8. Tongue posture of post-treatment was more raised than pretreatment. B. Deep bite case 1. The treatment time was 1 year 8 months. 2. Upper incisors showed intrusion and labioversion and lower incisors showed slight intrusion and linguoversion. 3. The lower molars showed distal uprighting and intrusion and upper molars showed mesial movement and extrusion. 4. Normal overbite and overjet were established. 5. Maxilla did not show downward movement. 6. Mandible showed slight clockwise rotation. 7. Lower lip showed retraction and downward drop and upper lip showed downward drop.

Background: This study was to investigate the relationship between scapular downward rotation ratio (SDRR), lower trapezius (LT) muscle, and rounded shoulder angle (RSA) on each side in subjects with scapular downward rotation syndrome (SDRS). Design: Cross-sectional Study Methods: Fifteen subjects have participated in this study. The RSA and SDRR were assessed using a tape measure in standing posture. The RSA was computed by the angle made by two lines: one was the distance between the root of the scapula and the acromion, and the other was the distance between the acromion and the horizontal line in the root of the scapula. The SDRR was computed by two horizontal lines: one was the distance between the mid-line and root of the scapula, and the other was the distance between the mid-line and inferior angle of the scapula. LT muscle strength was performed in a prone position by the hand-held dynamometer. Results: There was a positive correlation between SDRR and LT strength in the less affected sides (r=.59; p=.02), however, there was no correlation between RSA and LT strength in the more affected sides (p>.05).

Quenching phenomena of hemispherical downward facing convex surfaces with narrow gaps have been investigated experimentally. Experiments employed test sections having 1 and 2 mm in gap thickness and 1 atm in system pressure. From interpretations of the temperature and the heat flux history, it was found that the flooding inside the gap was restricted by CCFL phenomena and quenching process was propagated from lower to upper region of the internal copper shell. The ratio of the maximum heat fluxes at 1 mm to 2mm in gap thickness was the almost same that obtained by steady state experiments. The quenching scenario of the hemispherical downward facing surface with narrow gap has been suggested.
