This study was conducted to analyze variation in patient days and medical care benefits among finger-amputated patients due to industrial injury. The 242 personal data on medical care for finger-amputated patients due to industrial injury(131 in 1994, 111 in 1995) of Regional Labor Office were analyzed. The major results of this study were as follows: Patient days per case were 69. And the ratio of the maximum and the minimum among patient days for case was 26.6. Patient days per case in university hospital were 134.8 and the longest than other medical facilites. The ratio of the maximum and the minimum among the patient days per case was higher in hospital(24.7) than in other medical facilities. Benefits per case were 1,258,000 Won. And the ratio of the maximum and the minimum among benefits of case was 232.0. Case benefits was higher in university hospital (2,685,000 Won) than in other medicl facilities. The ratio of the maximum and the minimum among the benefits per case was higher in hospital(232.0) than in other medical facilities. Variation in patient days and medical care benefits per finger-amputated patient in industrial injury was large. This study results indicated need for a new industrial injury compensation insurance policy initiative for efficient utilization of medical resources and quality assurance. And the author thought that the results of this study would influence the policy for the industrial injury compensation insurance policy.

To find elements which enable improving Quality of image of chest radiography, we attempted to make comparison between chest radiography used currently with that of the past, and following conclusion was reached: 1) It could be confirmed that a dependance on chest radiography was declining, because proportion of chest radiography against overall radiography decreased. 2) There was a change of kVp to a high voltage in a chest radiography, and use of high kVp became a generalization 3) Exposure time was reduced and exposure dose was curtailed accordingly. 4) Apparatus was mainly comprised of 3-phase rectifier circuit and inverter type. 5) It could be confirmed that frequency of applying additional filters for high kVp radiography was insufficient. 6) There was almost no difference in the condition of exposure between hospitals using film/screen and hospitals using CR. But when CR is used for radiography, it was increase in exposure dose due to increase in tube current and it will be necessary to have continuous study on exposure dose by an increase use of CR in the future.

Summary of Background Data: Myofascial pain syndrome (MPS) is a common painful muscle disorder caused by trigger points occurring in myofascial. MPS is a major cause of chronical pain and is the subject of further clinical examination. Purpose: To uncover effective intramuscular stimulation therapy (IMS), the patients' actively participation stretching exercise and stabilizing around shoulder girdle where trigger point provoking myofascial pain syndrome in usually occurred. Methods: 45 myofascial pain syndrome patients were randomly chosen and divided into 3 groups. The first group (G1) received only IMS therapy, The second group (G2) had both IMS and active stretching exercises administered and the final group (G3) was given IMS therapy and stabilizing exercises. Therapy intervention was given for 3 weeks, 3 times a week and then only stretching exercise for the second group and stabilizing exercise for the third group was given for another 3 weeks. The visual analogue scale was dine before the experiment, 3 weeks after the experiment and 6weeks after the experiment to measure subjective degrees of pain and pressure pain threshold to measure sensitivity improvement of trigger point and functional ability questionnaire to measure daily life performance. Results: There were no significant changes after 3 weeks but after 6 weeks, between G1 and G2 and between G1 and G3 showed significant change of pain, pressure pain threshold and daily life performance. There were significant improvement of the measurement of degrees of pain, pressure pain threshold and improvement of daily life performance at different times for G1 showed change 3 weeks after the experiment, but there were no changes 6 weeks after the experiment. There were significant improvement of the measurement at different times for G2 and G3 showed change 3 weeks after the experiment and 6 weeks after the experiment. Conclusions: IMS therapy proved to be effective in inactivation of trigger points of the myofascial pain syndrome patients and stretching and stabilizing exercises beside it keep remedial value longer by improvement of pain and dysfunction that occurred by the trigger point.

The couple force of the scapular stabilizers for upward rotation that include the upper and lower trapezius, serratus anterior muscles is essential to maintain the stability of shoulder joint. But if there is and imbalance of these muscles, it would occur many problems of shoulder joint. A push-up plus exercise with an unstable support is used in order to increase the muscle activity and stimulate the proprioception of shoulder joint. The purpose of this study was to compare the muscle activity of upper and lower trapezius, serratus anterior muscles and to determine which exercise is more effective when subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects and 15 painful subjects with injury of shoulder joint participated in this study. Surface electromyography data were collected during plus phase of push-up plus exercise. The types of push-up plus exercise were composed of three conditions. Stable type is subjects performed the push-up plus exercise on the fixed support and unstable type 1 is on the sling without shaking and unstable type 2 is on the sling with shaking by tester's manual. The upper and lower trapezius activities of injured group were higher than uninjured group at three measure conditions, but serratus anterior activities were not. The UT/SA ratio of injured group was higher than uninjured group at three measure conditions. The serratus anterior activities were most high at unstable 2 measure in both groups. The UT/SA ratio was most low at unstable 2 measure condition in injured group only. The present result revealed that push-up plus exercise in the unstable support with shaking which took most high serratus anterior activities and most low of UT/SA ratio is optimal cure method that can improve the imbalance of the scapular stabilizer.

Statement of problem. Resin cements are widely used in adhesive dentistry specially on all ceramic restorations. It is needed to find out adequate bonding strength between different porcelain surface treatments, commercially available porcelains, and different resin cement systems. Purpose. The purpose of this study was to evaluate shear bond strength of resin cements bonded to porcelains in three different modalities; 5 different porcelain surface treatments, 3 different resin cement systems and 3 different commercially available pressable porcelains. Material and Method. This study consisted of 3 parts. Part I examined the effect of five different surface treatments on the pressable porcelain. Fifty discs (5 mm in diameter and 3 mm in height) of Authentic porcelain were randomly divided into 5 groups (n = 10). The specimens were sanded with 320 grit SiC paper followed by 600 grit SiC paper. The specimens were treated as follow: Group 1-Sandblasting (aluminum oxide) only, Group 2 - sandblasting/ silane, Group 3 - sandblasting/ acid etching/ silane, Group 4 - acid etching only, Group 5 - acid etching/ silane. Part II examined the shear bond strength of 3 different resin cement systems (Duolink, Variolink II, Rely X ARC) on acid etching/ silane treated Authentic pressable porcelain. Part 3 examined the shear bond strength of Duolink resin cement on 3 different pressable porcelains (Authentic, Empress I, Finesse). All cemented specimens were stored in distilled water for 2 hours and tested with Ultradent shear bond strength test jig under Universal Instron machine until fracture. An analysis of variance(ANOVA) test was used to evaluate differences in shear bond strength. Result. The shear bond strength test resulted in the following: (1) Acid etched porcelains recorded greater shear bond strength values to the sandblasted porcelains. (2) Silane treated porcelains recorded greater shear bond strength values to non-silane treated porcelains. (3) There was no significant difference between sandblasting/ acid etching/ silane treated and acid etching/ silane treated porcelains. However those values were much higher than other three groups. (4) The shear bond strength with Variolink II was lower than the value of Duolink or Rely X ARC. (5) The shear bond strength of Finesse was lower than the value of Authentic or Empress I.
