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.

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.

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.

Background: Arteriovenous malformation (AVM) which is a high-blood-flow lesion with connections between arteries and veins without an intervening capillary bed, is difficult to manage. The ear is the second most common site of extracranial AVM. However, studies regarding the management of this condition remain lacking. The purpose of this study was to share managing experiences in our center and to investigate the treatment effect through a retrospective analysis of cases. Methods: Among 265 patients with AVM treated in our vascular anomalies center between January 2008 and January 2021, 10 patients with auricular AVM were included in the study to investigate the lesion distribution, clinical stage, and treatment methods by performing a retrospective evaluation. Results: Among 10 patients, five patients had AVMs distributed in the upper half of the ear, one patient in the lower half of the ear, and four patients in whole ear, respectively. Seven patients had Schobinger stage II, and three had stage III. One patient received surgical treatment only, four patients received sclerotherapy only, and five patients received both surgical treatment and sclerotherapy. The posttreatment status was checked as controlled in two patients, improved in seven patients, persistent in one patient. There were no worsening patients. Conclusion: Auricular AVM is a disease that is difficult to manage by one specific department, thus requiring a collaborative management effort from multidisciplinary team.

Background: Interferon-${\gamma}$ assays based on tuberculosis (TB)-specific antigens have been utilized for diagnosing and ruling out latent TB and active TB, but their utility is still limited for TB incidence countries. The aim of this study is to understand the clinical utility of enzyme-linked immunospot (ELISpot) assays among patients with clinically suspected TB and healthy adults in clinical practices and community-based settings. Methods: The ELISpot assays (T SPOT.TB, Oxford Immunotec, UK) were prospectively performed in 202 patients. After excluding those with indeterminate results, 196 were included for analysis: 41 were TB patients, 93 were non-TB patients, and 62 were healthy adults. Results: The sensitivity and negative predictive values of the T SPOT.TB assays for the diagnosis of TB were 87.8% and 89.1%, respectively, among patients with suspected TB. The agreement between the tuberculin skin test (10-mm cutoff) and the T SPOT.TB assay was 66.1% (kappa=0.335) in all participants and 80.0% (kappa=0.412) in TB patients. Among those without TB (n=155), a past history of TB and fibrotic TB scar on chest X-rays were significant factors that yielded positive T SPOT.TB results. There was a significant difference in the magnitude of T SPOT.TB spot counts between TB patients and non-TB patients or healthy adults. Conclusion: The T SPOT.TB assay appeared to be a useful test for the diagnostic exclusion of TB. A positive result, however, should be cautiously interpreted for potential positives among those without active TB in intermediate TB incidence areas.
