The purpose of this study were to evaluate and compare the balance ability at different conditions in normal 20 to 29 years old on unstable platform, KAT 2000(Breg, Inc., Vista, CA. 1994). Static and dynamic BI(balance index) were measured 3psi and 5psi surface conditions. Static tests were done on right and left leg separately, then both legs together with the feet apart 20cm with the eyes opened and closed. Dynamic tests were done on both legs together with apart 20cm with the eyes opened. A dynamic test was performed in which the subject moved platform in a circular manner to chase a moving object on a computer screen. Seventy healthy students(average 21.6 years, male, female) were tested. In this study applied the paired t-test and correlation to determine the statistical significance of result. The results were as follow: 1) The mean static balance index of the Rt leg was $119.9{\pm}75.72$ on 3psi surface condition with the eyes opened, and that of the Lt leg was $224.3{\pm}121.16$. 2) The mean static balance index of the Rt leg was $93.1{\pm}24.16$ on 5psi surface condition with the eyes opened, and that of the Lt leg was $180.5{\pm}61.76$. 3) The mean static and dynamic balance index of both legs were $76.4{\pm}31.86$, $2187.6{\pm}696.99$ on 3psi with the eyes opened, and $68.3{\pm}14.82$, $1938.7{\pm}525.41$ on 5psi respectively. 4) The mean static balance index of the Rt leg was $517.8{\pm}220.87$ on 3psi surface condition with the eyes closed, and that of the Lt leg was $588.6{\pm}204.81$. 5) The mean static balance index of the Rt leg was $271.9{\pm}192.151$ on 5psi surface condition with the eyes closed, and that of the Lt leg was $363.4{\pm}98.97$. 6) The mean static balance index of both legs was $332.6{\pm}137.31$ on 3psi surface condition with the eyes closed, and that of the 5psi was $288.5{\pm}133.07$. 7) The balance index on 3psi surface condition was significantly higher than that of 5psi (p<0.05, p<0.01). 8) The balance index with the eyes closed was significantly higher than that of the eyes opened (p<0.05). 9) The balance index on the left leg was significantly higher than that of the right leg (p<0.05, p<0.01). 10) There was no correlation between static balance index and dynamic balance index. 11) Therewas no correlation between weight or height and balance index.

As compared before, agricultural machines are used more commonly instead of animal or manpower in rural areas and the injuries due to those are common. This study was conducted by questionnaire method in order to find out the current status of injuries due to agricultural machines for farmers who was selected from three Gun's in Kyeongsangnam Province. The study subjects were 385 persons in all(210 male persons, 175 female reasons) and the study period was from July through September 1993. The results were as follows; 1. The injury rate due to agricultural machines was high in male(p<0.05), and it was higher in younger age group and higher educated group. 2. The injury occurred high in summer and autumn seasons(77.6%), in the afternoon(60.6%), and during harvest(35.2%). 3. The major injuries were contusion, fracture, amputation in order and the injured sites were arms, legs, and chest in order. 31.7% of the injured farmers had been admitted, and they were treated at hospitals, home, drugstores and health centers in order. 4. The casualty damage was highest by cultivators, and agricultural instruments, threshing machine were followed. Among traumatic injuries concerned with cultivators contusions were most common, and fractures, amputations were followed. In case of agricultural instruments bruises were most common, and incisions, contusion were followed. In case of threshing machines fractures were most common and contusion, bruise were followed.

In order to clarify the interspecific variation of Astiphrom jezoense, a morphometric analysis was performed for seven populations using PCA (principle component analysis) and discriminant analysis. As a result of PCA, 25 quantitative characters are grouped into four factors. The characteristics on legs are especially important components both in male and in female. Morphometric analysis indicate that considerable morphological gap is correlated with geographical habitat. Important discriminant characters are MOD (maximum ocellar distance), Fn (first tergite length) in female and MSL (malar space length) in male.

Objectives : The purpose of this study was to assess the efficacy of Chuna and taping treatment in patients with genu varum. Methods : Twenty-seven patients(male:10, female:17) with genu varum were recruited in this study. Chuna treatment at pelvic, and taping treatment at both legs were applied to whole participants. Outcomes were assessed using Q-angle(Quadriceps angle, QA), tibiofemoral angle(TFA), width and length of lesser trochanter(LT), pelvic incidence(PI), pelvic(PT), sacral slope(SS), lumber lordosis angle(LLA), meridian-electromyography(MEMG), Korean western ontario and McMaster universities osteoarthritis index(KWOMAC), and distance of femoral intercondylar distance(ICD). Results : 1. QA, LT width and LT length in radiograph were significantly increased. 2. PI, SS, PT and TFA in radiograph were significantly decreased. 3. The left vastus medialis portion contraction of female was significantly decreased after treatment. 4. The left rectus femoris portion fatigue was significantly decreased after treatment in male subjects. 5. The vastus medialis portion fatigue was significantly decreased after treatment in female subjects. 6. The distance of femoral ICD was significantly decreased. Conclusions : This study showed that Chuna and taping treatment could be used as an effective method for the treatment of genu varum.

A new genus with a new species of poecilostomatoid copepod, Polyankylis orientalis, is described based on a pair of specimens collected from a tide pool on muddy shore in Korea. It represents a new family of the lichomolgoid complex with the following distinguishing characters: (1) 6-segmented antennule (resulted from the fusion of the third and fourth segments) with additional aesthetascs in male, (2) hook on mediodistal corner of antennal coxobasis (first segment), (3) proximal and distal scales on the outer margin of mandible present, (4) main axis of mandibular gnathobase short and lacking notches at the base of mandibular lash, and (5) inner margin of mandibular lash with denticulate processes. Additionally, maxillar syncoxa carries a large, pointed process on ventral surface, legs 1-4 do not show sexua1 dimorphism, and leg 4 is uniramous with 1-segmented exopod. A detailed discussion is given of its affinities with the ten existing families of the lichomolgoid complex.

Nontraumatic intracranial subarachnoid hemorrhage (SAH) attributable to the thoracolumbar dural arteriovenous fistulas (DAVFs) has been extremely rare. A 41-year-old male patient was admitted with severe acute headache, neck stiffness, and pronounced low-back pain radiating to both legs. The T2-weighted MR imaging showed irregular signal void and enlarged, varix like pouch formation with spinal cord compression at the T11-12 level. The angiogram revealed a DAVF. We report a DAVF case with SAH that revealed an extensive infarction from C5 to the conus medullaris after undergoing operative treatment.

Intramedullary spinal hemagioblastomas usually develope in cervical or thoracic region of spinal cord, but rarely in conus medullaris. We report a case of hemangioblastoma developed in conus medullaris. The 19-year-old male patient presented with slowly progressing low back pain and paresthesia of both legs. MRI and spinal angiography revealed a well-vascularized mass lesion in the conus medullaris with syrinx formation. Total excision of hemangioblastoma was achieved via posterior approach. Postoperatively, patient's walking difficulty was worsened transiently, but it was improved at discharge.

Several differences are revealed in the segmentation and setation of the antennule, maxillule, maxilliped and fifth legs between three genera of the family Metridinidae, Metridia, Pleuromamma, and Gaussia. The phylogenetic relationships are cladistically analyzed on the basis of 10 morphological characters. The cladogram shows that Gaussia and Pleuromamma form a sister group, with Metridia which is the first branch to diverge within the family. The presence Of quadritheks on the male antennules of Metridia and Pleuromamma seems to be an important synapomorphy. The loss of quadritheks in Gaussia represents likely evidence of a character reversal into the ancestral condition.
