Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

The patellar tendon is known as the strongest material for the substitution of anterior cruciate ligament. There are many technical difficulties in reconstruction of the ligament with this tendon since patellar aponeurosis is weak, and the length of the tendon is restricted, and the adquate insertion in proper place is difficult. Authors harvested the middle 1/3 of patellar tendon c bone block of tibial tubercle and patella with the superficial layer of the quadriceps tendon left attached. The large triangular tibial tubercle piece was impacted into the femoral tunnel from distally to proximally, of which the orifice is the very place of the middle of the original anterior cruciate ligament. Two bundles of 0-dexon sutures made at the tibial tubercle portion, were pulled through to different outlet of femoral condyle during this procedure and were tied over the cortical bone of lateral supracondylar region. The tendon twisted 180°(clockwise for the right knee and counter-clockwise for the left knee) to adapt to screwhome movement. The patellar piece was fixed at the isometric point in full flexion and extension, which is usually the middle point of original tibial insertion c one or two barbed staples made at the original position of tibial insertion of the ligament. We tried this methods in 26 knees (12 vascularized grafts and 14 free grafts) and was followed for more than one year and the results was compared with those of 12 knees of original McIntosh operation (follow up period: 16-72 months, average 34.3 months). The instability were evaluated c Lachman test and OSI sagittal knee tester. The knee of negative Lachman test & pivot shift test was defined as "normal" The results were as follows;l. In modified McIntosh operation group negative Lachman test was noted only in 6 knees (50.0 % ) and there were 2 knees (16.7% ) of GI, II & III, respectively. 2. In vascularized bone block patellar tendon graft group II out of 12 knees (91.7%) showed negative Lachman test and only one knee (8.3%) revealed G II. 3. In free bone block patellar tendon graft 13 out of 14 knees (92.9%) showed negative Lachman test and the other one knee (7.1%) revealed GI. 4, The overall success rate (normal) of bone block patellar tendon graft was 92.3%. The success rate of patellar tendon bone block operation was significantly higher than that of modified McIntosh operation (χ²=6.48, df=1, P=0.0109) and there was no statististical difference between vascularized and free graft group (χ²=0.39, df=l, P=0.5322).

During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complication. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-up in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examination in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examination in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis(n=5) and perforated appendicitis(n=1). Our results show that high-resolution, real-time US is an accureate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complication.

The household survey was performed in a urban slum and a rural Chonnam areas to measure the level of illness and medical care utilization and to find the determinants of physician utilization. The data revealed that age-adjusted prevalence rates of acute and chronic diseases were much the same in both areas ranged between 10.0 to 11.3%. But medical care utilization was more frequent in urban slum than in rural area. The facility of the first medical contact was also different. Some personal and disease related variables including disease severity and activity restricted day were significantly, but somewhat differently by area, associated with physician utilization pattern. When applying Anderson model, the medical need factors explained 42.2 and 40.4% of physician utilization in urban slum and in rural areas respectively, while the enabling factors explained 18.0 and 12.2% and the predisposing factors explained 17.1 and 8.9% correspondingly.

PURPOSE: To compare the value of Gd-DTPA enhanced, fat-suppression T1-weighted (Gd-FST1SE) MR images in thediagnosis of female pelvic disorders with that of fast spin-echo T1-weighted(T1FSE) and fast spin-echoT2-weighted(T2FSE) MR images. MATERIALS AND METHODS: Pelvic MR images of 42 women (24 ovarian disorders, 19uterine disorders) were reviewed by two radiologists. Discrimination of normal anatomic structures, identificationof pathologic lesions and recognition of internal structure of the lesions such as solid and cystic portion,papillary nodule, septa and wall were evaluated using a scoring system. The Friedman two-way ANOVA test was usedfor data analysis. RESULT: T2FSE was useful for evaluation of the uterine cervix(T1/T2/Gd, 2.5/3.9/2.8,respectively), junctional zone(1.6/3.1/2.5), endometrium (2.0/3.3/3.0), ovary(1.1/2.1/1.7) and uterine myoma(1.7/2.4/2.1)(P<0.001), but secondary degeneration was best visualized on Gd-FS T1SE. The Gd-FS T1SE ;lymphadenopathy(3.4/1.5/3.7) was better visualised on this modality than on eithor TIFSE or T2FSE. Gd-FS T1SEimages also clearly depicted papillary projection(2.4/3.1/3.8) and the solid component (2.9/3.1/3.5) of ovariancystic neoplasm(P<0.01). The confidence level in the identification of ovarian mass, internal septation andsurrounding wall of cystic neoplasm was not improved on Gd-FS T1SE. CONCLUSION: The Gd-FS T1SE images were usefulfor the evaluation of metastatic lymphadenopathy in uterine cervical malignancy and for identification of thesolid component and papillary projection of ovarian cystic neoplasm.
