  • 악관절 동통은 여러 가지 원인에 의해 발생하는 것으로서 동통을 호소하는 환자에서 Bone SPECT의 유용성을 알아보았다. 악관절 동통을 호소하여 Bone SPECT를 시행한 34명을 대상으로 하였으며 모든 환자에서 단순 촬영, planar 골스캔, Bone SPECT를 시행하였다. Bone SPECT에서 동위원소의 섭취 증가 정도에 따라 3가지로 분류하였다. Grade 0은 정상, Grade I은 후두골과 비슷한 섭취 증가, Grade II는 상악동과 비슷한 섭취 증가가 있는 것으로 정하여 각각 섭취 증가 정도에 따라 환자의 임상 증상과 치료 방법을 비교 분석했다. 34예중 27예 (80%)에서 악관절 Bone SPECT 시행시 섭취 증가가 있었고, 이중 21예 (78%)에서 하악과두에 섭취 증가가 있었고 나머지 6예 (22%)에서 하악궁과 상악궁에 섭취가 있었는데 이들은 치주질환으로 확인되었다. 총 34예중 Grade 0인 7예 (20%)에서는 관절 잡음이 3예 있었고 4예에서 약물 치료로 증상이 호전되었고 나머지 3예에서 치료 없이 증상이 호전되었다. Grade I 인 4예(12%)에서는 관절잡음이 3예 있었고 모두 약뭍 치료로 증상이 호전되었다. Grade II 23예(68%)중 관절 잡음은 7예 있었고 14예에서 약물치료 및 관절천자와 같은 감압술을 병행하여 증상이 호전되었다. 6예에서는 치주 치료로 증상이 호전되었다. 총 34예중 평면 골스캔에서는 11예(32%)에서 섭취 증가가 있었다. 단순 촬영에서는 16예(47%)에서 관절내강 협소 혹은 팽대, 골리란, 관절운동 제한 등이 관찰되었다. one SPECT는 악관절 동통 환자에서 유용하게 사용할 수 있는 진단적 방법이며, 치료방법을 결정하는 데 도움이 되었다. 동위원소 섭취 증가가 많을 수록 환자 치료에 보다 적극적인 치료를 필요로 하였으나 임상 증상과 동위원소 섭취증가는 밀접한 관계는 없었다.

  • Purpose : The purpose of this study was to compare the effects of Joing Mobilization and Group back Pain Exercise Program on the disability level and the pain of flexibility and the back muscle strength in the hearing impairment patients with Low back pain. Methods : The subjects of this study were 12 patients, 8 males and females. They visited clinic for physical treatment within 6 months after onset of low back pain. One group was applied with Joing Mobilization and other group was with Group back Pain Exercise Program. The patient were treated special program 3 times session weekly. And treatment 2 times session was 15min with physiotherapy weekly. The muscle strength was measured by Cybex 660, the level of disability by Oswestry low back pain disability scale, the intensity of pain by visual analogue scale (VAS). The data was analysed by paired T-test and independent T-test. Results : The results of this study were summarized as follow : 1. The Oswestry disability score of experimental and control group were significantly decreased and there was no difference in the Oswestry disability score change between joint mobilization group and back pain exercise group. 2. The pains in anterior, postrior, lift lateral and right lateral bending and in rotation of back pain exercise group were significantly increased compared with those of joint mobilization group. 3. The flexors and extensors peak torque of back pain exercise group were significantly increased at test velocities $30^{\circ}$/sec, $60^{\circ}$/sec compared with those of the joint mobilization group. There was no significant difference in extensors and flexors peak torque at $30^{\circ}$/sec, $60^{\circ}$/sec between two group. The results showed that the back pain exercise group were effective in decreasing disability score and pain of trunk activity, increasing trunk extension and flexion peak torque. Conclusion : It is suggested theat the back pain exercise program could be an essential factor for the effective intervension to the hearing impairment patients suffere from low back pain.

  • Bonica defined, that reflex sympathetic dystrophy (RSD) may develop pain, vasomotor abnoramalities, delayed functional recovery, and dystrophic changes on an affected area without major neurologic injury following trauma, surgery or one of several diseased states. This 45 year old male patient had been crushed on his left shoulder by a heavily laden rear car, during his job street cleaning about 10 years ago (1978). At first the pain was localizea only to the site of injury, but with time, it spreaded from the shoulder to the elbow and hand, with swelling. X-ray studies in the local clinic, showed no bone abnormalities of the affected site. During about 10 years following the injury, the had recieved several types of treatments such as nonsteroidal analgesics, steroid injections into the glenoidal cavity (10 times), physical therapy, some oriental herb medicines, and acupuncture over a period of 1~3 months annually. His shoulder pain and it's joint dysfunction persisted with recurrent paroxysmal aggrevation because of being mismanaged or neglected for a sufficiently long period these fore permiting progression of the sympathetic imbalance. On July 14 1988 when he visited our clinic. He complained of burning, aching and had a hyperpathic response or hyperesthesia in touch from the shoulder girdle to the elbow and the hand. Also the skin of the affected area was pale, cold, and there was much sweating of the axilla and palm, but no edema. The shoulder girdle was unable to move due to joint pain with marked weakness. We confirmed skin temperatures $5^{\circ}C$ lower than those of the unaffected axilla, elbow and palm of his hand, and his nails were slightly ridged with lateral arching and some were brittle. On X-ray findings of both the shoulder AP & lateral view, the left humerus and joint area showed diffuse post-traumatic osteoporosis and fibrous ankylozing with an osteoarthritis-like appearance. For evaluating the RSD and it's relief of pain, the left cervical sympathetic ganglion was blocked by injecting 0.5% bupivacaine 5 ml with normal saline 5 ml (=SGB). After 15 minutes following the SGB, the clinical efficacy of the block by the patients subjective score of pain intensity (=PSSPI), showed a 50% reduction of his shoulder and arm pain, which was burning in quality, and a hyperpathic response against palpation by the examiner. The skin temperatures of the axilla and palm rose to $4{\sim}5^{\circ}C$ more than those before the SGB. He felt that his left face and upper extremity became warmer than before the SGB, and that he had reduced sweating on his axilla and his palm. Horner's sign was also observed on his face and eyes. But his deep shoulder joint pain was not improved. For the control of the remaining shoulder joint pain, after 45 minutes following the SGB, a somatic sensory block was performed by injecting 0.5% bupivacaine 6 ml mixed with salmon calcitonin, $Tridol^{(R)}$, $Polydyn^{(R)}$ and triamcinolone into the fossa of the acromioclavicular joint region. The clinical effect of the somatic block showed an 80% releif of the deep joint pain by the PSSPI of the joint motion. Both blocks, as the above mentioned, were repeated a total of 28 times respectively, during 6 months, except the steroid was used just 3 times from the start. For maintaining the relieved pain level whilst using both blocks, we prescribed a low dose of clonazepam, prazocin, $Etravil^{(R)}$, codeine, etodolac micronized and antacids over 6 months. The result of the treatments were as follows; 1) The burning, aching and hyperpathic condition which accompanied with vaosmotor and pseudomotor dysfunction, disappeared gradually to almost nothing, within 3 weeks from the starting of the blocks every other day. 2) The joint disability of the affected area was improved little by little within 6 months. 3) The post-traumatic osteoporosis, fibrous ankylosis and marginal sclerosis with a narrowed joint, showed not much improvement on the X-ray findings (on April 25, 1989) 10 months later in the follow-up. 4) Now he has returned to his job as a street cleaner.

  • We consider the problem of modeling count data where the observation period is determined by the life time of the system under study. We assume random effects or a frailty model to allow for a possible association between the death times and the counts. We assume that, given a random effect or a frailty, the death times follow a Weibull distribution with a hazard rate. For the counts, given a frailty, a Poisson process is assumed with the intensity depending on time. A gamma distribution is assumed for the frailty model. Maximum likelihood estimators of the model parameters are obtained. A model for the time to death and the number of failures system received is constructed and consequences of the model are examined.

  • The aim of this study is to investigate the effect of vertical ground motion (VGM) on seismic behavior of reinforced concrete (RC) regular frame with construction joints, and determine more proper modeling method for cast-in-situ RC frame. The four-story RC frames in the regions of 7, 8 and 9 earthquake intensity were analyzed with nonlinear dynamic time-history method. Two different methods of ground motion input, horizontal ground motion (HGM) input only, VGM and HGM input simultaneously were performed. Seismic responses in terms of the maximum vertex displacement, the maximum inter-story drift distribution and the plastic hinge distribution were analyzed. The results show that VGM might increase or decrease the horizontal maximum vertex displacement depending on the value of axial load ratio of column. And it will increase the maximum inter-story drift and change its distribution. Finally, proper modeling method is proposed according to the distribution of plastic hinges, which is in well agreement with the actual earthquake damage.

  • Recently a number of social surveys on community response to environmental noises have been conducted to summarize response relationship obtained from different areas. Some problems have been pointed out in comparing the result of surveys using verbal scales with different number of categories. ICBEN (International Commission on Biological Environment of Noise) Team 6 planned a international joint study and constructed comparable standardized noise annoyance scales using the same method. In Korea the survey was conducted in four areas such as Seoul, Taejon, Taegu, Kwangju. About 100 subjects participated in each area approximately. Finally five verbal annoyance were constructed as follows; 1 (Jeonhyu), 2 (Jokm), 3 (Bikyojerk), 4 (Ajoo), 5 (Umcheongnage).

  • Since many design problems in the railroad, aerospace and machine structures involve considerations of the effect of cyclic loading, manufacturing and quality control processes must fully account for fatigue of critical components. Due to the sensitivity of the Paris law, it is very important to calculate the ΔK numerically to minimize the error of predicted fatigue life in cycles. It is shown that the p-version of FEM based on LEFM analysis is far better suited for computing the stress intensity factors than the conventional h-version. To demonstrate the proficiency of the proposed scheme, the welded T-joint with crack problem of box car body bolster assembly and a crack problem emanating Iron a circular hole in finite strip have been solved.

  • Recently, square hollow section (S.H.S) is frequently used for column and H-section for beam of steel building structures. The connection between S.H.S column and H-beam is found to weaken the rotational restraint of the joint. Several types of detail to overcome the problem have been suggested for the connection between concrete filled S.H.S column and concrete composited H-bean In this paper, modelling technique to monitor the behavior of the connections is proposed. Then, Drucker-Prager yield criteria is introduced to simulate yield behavior of in-fill concrete while Von-Mises was used in earlier works. Gap-elements are also introduced to simulate the interaction between S.H.S columns and the in-fill concrete as in privious papers. axial forces are applied to S.H.S columns and made to vary in intensity and eccentricity.

  • We consider the problem of modeling count data where the observation period is determined by the survival time of the individual under study. We assume random effects or frailty model to allow for a possible association between the death times and the counts. We assume that, given a random effect, the death times follow a Weibull distribution with a rate that depends on some covariates. For the counts, given the random effect, a Poisson process is assumed with the intensity depending on time and the covariates. A gamma model is assumed for the random effect. Maximum likelihood estimators of the model parameters are obtained. The model is applied to data set of patients with breast cancer who received a bone marrow transplant. A model for the time to death and the number of supportive transfusions a patient received is constructed and consequences of the model are examined.
