The imbalance of rotator muscles of shoulder frequently causes shoulder injury in many baseball players. This study was intended to evaluate the strength characteristics of external and internal rotator muscles in high school baseball players. Isokinetic tests of external/internal rotators were performed using Cybex Ⅱ^+ Isokinetic dynamometer in nine pitchers, thirteen nonpitchers and twenty normal control subjects. And the flexibility of external rotator muscles of shoulder was evaluated by the hand-to-shoulder-blade Test. The results were as follows : 1) In pitchers, mean peak torque ratios of external/internal rotators were significantly high in nondominant side at 180 and 300 deg/sec, mean peak torque and mean peak torque body weight ratios of external rotators were significantly high in nondominant side at 180 deg/sec, 180 and 300 deg/sec respectively, mean peak torque of internal rotators were significantly high in dominant side at 300 deg/sec. 2) In nonpitchers, peak torque ratios of external/internal rotators were significantly high in nondo minant side at 180 deg/sec, but peak torque and peak torque body weight ratios of internal rotators were both significantly high in dominant side at 180 and 300 deg/sec. 3) In comparison between pitchers and nonpitchers, peak torque ratios of external/internal rotators in dominant side were significantly high in nonpitchers at 180 and 300 deg/sec, but there were no significant differences in nondominant side. 4) In flexibility tests of external rotators, pitchers showed statistically significant tightness in external rotators than nonpitchers and control group in dominant side, but there were no statistically significant differences in nondominant side. In conclusion, pitchers showed weakness and tightness in shoulder external rotators, which may lead to major shoulder injury. Therefore evaluation of muscle power and flexibility was thought to be one of the very useful screening tests for the prevention of shoulder injury.

The normal gait is largely devided by the stance phase and the swing phase, and each motion of joints and activities of muscles varies with the cycle of gait. The important parts in the gait determinants are motions of pelvic, knee and ankle joint, and the pathologic gaits are usually caused by unbalance of muscles, joint contracture, leg length discrepancy, spasticity and pain, etc. There is no objective data on the normal and pathologic gait analysis with 3-dimensional motion analyzer by now in Korea. The authors measured the ROM of each joint on the parameters of gait with 3-dimensional motion analyzer in order to obtain the standard data of normal gait and furthermore to compare the normal gait with the pathologic gait. The 10 normal men were the subjects of this investigation with 3-dimensional motion analyzer in Ergonomic Lab. of Korea Research Institude of Standards & Science. The results were as follows; 1) The mean stiride length of the subjects were 97.86cm. 2) The ratio of the stance phase to the swing phase were 57.8% to 42.2%. 3) The mean ROM of hip, knee and ankle joint were 153.8˚, 170.4˚ and 100.1˚, respectively, at initial contact on gait cycle. 4) The mean ROM of hip, knee and ankle joint were 159.7˚, 167.2˚ and 90.9˚, respectively, at foot flat on gait cycle. 5) The mean ROM of hip, knee and ankle joint were 165.7˚, 167.3˚ and 80.3˚, respectively, at heel off on gait cycle. 6) The mean ROM of hip, knee and ankle joint were 170.1˚, 148.2˚ and 89.9˚, respectively, at toe off on gait cycle. 7) The mean ROM of hip, knee and ankle joint were 156.9˚, 134.4˚ and 82.4˚, respectively, at mid swing on gait cycle. 8) The mean changes of ROM in normal gait were hip joint 20.7˚, Knee joint 50.7˚ and ankle joint 32.5˚, and knee joint showed the most various ROM changes.

The purposes of this study were to obtain information about the registered physically disabled and to find out problems in current disability grading for the registration of the disabled. Fortynine registered disabled people who lived in Wolpyeong Dong, Taejon as of June 1, 1994 were evaluated to grade their disability according to the disability grading table currently in use by one physiatrist, one senior resident in rehabilitation medicine and one general physician at the same time allowing no mutual communication among the raters. These re-evaluated disability grades were compared to the initial disability grades recorded in their disability registry. The results were as follows ; 1) The most common disability group was cerebrovascular accident group(10 cases, 20%), and most frequently participated physician in initial evaluation was orthopedic surgeon(16 cases, 33%). 2) The period from initial evaluation to re-evaluation was from 2 months to 6 years(mean 2.9 years). 3) There were statistically significant differences (P<0.05) between initial disability grades and re-evaluated disability grades. 4) There was no statistically significant differences(P>0.05) among re-evaluated disability grades by three examiners. 5) For the group from cerebrovascular accident and traumatic brain injury, there was no statistically significant differences(P>0.05) between physiatrist and resident, but there was statistically significant differences(P<0.05) between physiatrist and general physician, resident and general physician, respectively. From the above results, the disability grade table seemed to be so general that can be used by the physicians regardless of training in rehabilitation medicine. The disability grade table should be modified and supplemented specifically in statements of symptoms of the acquired brain dysfunction such as cerebrovascular accident and traumatic brain injury, and should include the criteria for the duration since the onset of disability to the evaluation for registration and necessity of re-evaluation over time.

췌장에서 발생하는 장액성 낭종 중에서 고형 변이성 장액 성 낭종은 매우 드물게 발생하는 질환이지만 악성 혹은 전 암성 병변과의 감별이 어려워서 수술이 필요한 다른 질환으 로 오인되는 경우가 매우 많다. 이에 저자들은 췌장의 신경 내분비종양으로 오인하고 수술을 시행하여 고형 변이성 장 액성 낭종으로 진단된 매우 드문 증례를 경험하였기에 문헌 고찰과 함께 보고한다. Rapid advancements, access to and use of imaging techniques have increased the frequency of identification of pancreatic cystic neoplasms in clinical practice. However, a diagnostic dilemma among pancreatic cystic neoplasms remains. Solid variant serous cystadenoma is extremely rare and difficult to accurately diagnose preoperatively, as they are commonly mistaken for malignant solid tumors of other types. Here, we present a case of a solid variant serous cystadenoma preoperatively misdiagnosed as a neuroendocrine tumor of the pancreas with a review of the relevant literature.
